Referring to fig. 5 to 7, one end of the limiting support contact 232, which is far away from the first linear driver 233, is provided with a conical anti-slip surface 2321, a plurality of limiting slide rails 2322 are arranged in the limiting support contact 232, a sliding adjusting block 2323 is further arranged in the limiting slide rails 2322, an adjusting screw 2324 is arranged at the axis position of the limiting slide rails 2322, the adjusting screw 2324 is in threaded connection with the sliding adjusting block 2323, a sliding support rod 2325 is arranged in the limiting slide rails 2322, an expanding connecting rod 2326 is arranged between the sliding support rod 2325 and the sliding adjusting block 2323, a plurality of second limiting holes 2329 are formed in the side portion of the limiting support contact 232, a second anti-rotation limiting disc 2327 is arranged on the side portion of the adjusting screw 2324, and a second positioning threaded hole 2328 is formed in the second anti-rotation limiting disc 2327.
The sliding support rod 2325 is used for limiting holes of the winding drum 1, when the position of the sliding support rod 2325 needs to be adjusted to adapt to winding drums 1 with different sizes, the adjusting screw 2324 is rotated, and due to threaded connection with the sliding adjusting block 2323, the sliding adjusting block 2323 is driven to move along the limiting sliding rail 2322. When the sliding adjusting block 2323 moves, the sliding supporting rod 2325 is pushed or pulled to perform synchronous adjustment under the action of the expanding connecting rod 2326. The sliding support bar 2325 in the limiting support contact 232 is adaptively adjusted according to the size of the hole of the winding drum 1, so that the stability and adaptability of fixation are improved. After the adjusting screw 2324 is adjusted to a proper position, in order to prevent the fixing effect from being affected by accidental rotation, a worker can pass through the second positioning threaded hole 2328 on the second anti-rotation limiting disc 2327 through a bolt to be connected with the corresponding second limiting hole 2329. Thus, the adjusting screw 2324 is fixed at the current position, and stability and reliability of the sliding support bar 2325 are ensured.
The conical anti-slip surface 2321 of the limiting contact 232 can increase the contact friction force with the hole of the winding drum 1, so that the winding drum 1 can be effectively driven to synchronously rotate when the limiting contact 232 rotates.
Referring to fig. 1, 8 and 9, the adaptive feeding device 3 includes a bidirectional adjusting screw sliding table 31 disposed beside the multi-specification winding device 2, a linear conveyor 32 is mounted on a movable end of the bidirectional adjusting screw sliding table 31, an interval conveyor belt 33 is mounted on the linear conveyor 32, a first infrared sensor is mounted on the linear conveyor 32, and the adaptive feeding device 3 further includes a movable placement device 34 disposed below the multi-specification winding device 2.
The bidirectional adjusting screw sliding table 31 can accurately adjust the width of the linear conveyor 32. The adjustment function allows the linear conveyor 32 to accommodate reels 1 of different lengths. The linear conveyor 32 is provided with a spacing conveyor belt 33. The design of the spacer conveyor 33 ensures that the reels 1 can maintain a certain distance during the transport, avoiding collisions or stacking. It is important for the subsequent mobile depositing device 34 to grasp the reels 1 accurately, since it allows for an independent operating space for each reel 1. A first infrared sensor mounted on the linear conveyor 32 is used to monitor the position of the spool 1 in real time. When the reel 1 is placed on the conveyor belt and moved to the sensor detection area, the sensor immediately senses the presence of the reel 1 and transmits this signal to the control system. A movable placement device 34 is arranged below the multi-specification winding device 2 and is responsible for accurately placing the winding drum 1 on the linear conveyor 32 into a specified area of the multi-specification winding device 2. When the first infrared sensor detects that the winding drum 1 reaches the preset position, the movable placement device 34 is quickly started to grasp the winding drum 1 from the conveying belt and place the winding drum 1 into the clamping mechanism of the multi-specification winding device 2 stably. At this time, the limiting pressing device 23 can immediately limit and press against the winding drum 1, so as to ensure that the winding drum is stable in the winding process. The high-efficiency and accurate feeding of the reels 1 with different sizes is realized.
Referring to fig. 8 and 9, the movable placement device 34 includes a fixed mounting frame 341, a rotating bracket 342 is mounted on the fixed mounting frame 341, a first rotary driver 343 is mounted on a side portion of the fixed mounting frame 341, an output end of the first rotary driver 343 is in transmission connection with the rotating bracket 342, a limiting clamping frame 345 is further mounted on the rotating bracket 342, a receiving groove 3451 is arranged on the limiting clamping frame 345, a second linear driver 344 is further mounted on the rotating bracket 342, and an output end of the second linear driver 344 is in transmission connection with the limiting clamping frame 345.
The fixed mount 341 is provided at a side thereof with a first rotary driver 343, an output end of which is in driving connection with the rotary bracket 342. When the placement position or direction of the winding drum 1 needs to be adjusted, the control system sends an instruction to the first rotary driver 343, and the first driver drives the rotary bracket 342 to rotate to a specified angle, so as to ensure that the limit clamping frame 345 can be accurately aligned with the winding drum 1 or the multi-specification winding device 2 on the linear conveyor 32, the limit clamping frame 345 is mounted on the rotary bracket 342, and the limit clamping frame 345 is provided with a receiving groove 3451. The shape and size of the receiving channel 3451 is carefully designed to ensure that the spool 1 is stably carried. When the rotating frame 342 is rotated to a correct position, the limit clamping frame 345 is lowered to a proper height, and the receiving groove 3451 is aligned with the winding drum 1 on the linear conveyor 32, so as to prepare for the grabbing operation. A second linear actuator 344 is also mounted on the rotating bracket 342. When the first infrared sensor detects that the spool 1 reaches the preset position, the control system activates the second linear actuator 344. The driver pushes the limiting clamping frame 345 to move forward, so that the receiving groove 3451 is tightly attached to the winding drum 1. After the grabbing of the spool 1 is completed, the first rotary driver 343 is started again, so as to drive the rotary bracket 342 and the limiting clamping bracket 345 to rotate to the multi-specification winding device 2. The winding drum 1 is fixed by the multi-specification winding device 2. After the placement of the roll 1 is completed, the placement device 34 is moved to perform a reset operation. The first rotary driver 343 drives the rotary bracket 342 to rotate back to the initial position, and the second linear driver 344 pushes the limit clamping frame 345 to retract to the initial height, so as to prepare for the next grabbing and placing operation. In the whole process, the control system can monitor the motion state of each part in real time and adjust and optimize the motion state according to the needs so as to ensure the smooth proceeding of the whole feeding process.
Referring to fig. 9 and 10, an inclined guide surface is provided above the guide blanking rail 4, a telescopic guide rod 41 is mounted on the guide blanking rail 4, a third linear driver 42 is mounted at the material receiving end of the inclined guide surface, and the output end of the third linear driver 42 is in transmission connection with the telescopic guide rod 41.
An inclined guide surface is arranged above the guide discharging rail 4 and is inclined at a certain angle, so that the winding drum 1 can slide downwards by means of self gravity. On the guide blanking rail 4 are mounted telescopic guide rods 41, which can be adjusted in length and position as desired. The material receiving end of the inclined guide surface is provided with a third linear driver 42, and the third linear driver 42 is in transmission connection with the telescopic guide rod 41. When the multi-specification winding device 2 needs to feed the wound roll 1, the third linear driver 42 will start and push the telescopic guiding rod 41 to extend to the lower side of the roll 1. This ensures that the spool 1 can be smoothly moved along the telescopic guide rod 41 to the guide blanking rail 4 after the release of the fixing. Subsequently, the multi-gauge winding device 2 releases the fixation of the winding drum 1, and the wound winding drum 1 naturally slides down to the area to be treated along the inclined guide surface and the telescopic guide rod 41.
Referring to fig. 9 and 10, the film roll tail laminating device 43 includes a limit blocking block 432 mounted on the guide blanking rail 4, the limit blocking block 432 is slidably connected with the guide blanking rail 4, a plurality of driving wheels 433 are mounted on the guide blanking rail 4, an adsorption spraying rail 435 is mounted below the driving wheels 433, a visual detector 436 is mounted on the adsorption spraying rail 435, an adsorption pipeline is mounted on one side of the adsorption spraying rail 435, a spraying pipeline is disposed on one side of the spraying rail 435 far from the adsorption pipeline, a second infrared sensor is mounted in the spraying rail 435, a fixing support 437 is mounted on the side of the guide blanking rail 4, and a rotary pressing plate 438 is mounted on the fixing support 437.
The fourth linear actuator 431 controls the limit stopper 432 to move in a telescopic manner. Initially, the limit stop block 432 is in a contracted state, allowing the spool 1 to move freely on the guide blanking track 4. The driving wheel 433 is mounted on the driving wheel 433 of the guide discharging rail 4, and its rotation is controlled by the second rotary drive 434. Initially, the drive wheel 433 is in a stationary state. A visual detector 436 is mounted on the suction spray rail 435 for monitoring the position of the film tail in real time. The adsorption spray rail 435 includes adsorption piping and spray piping for adsorbing and spraying adhesive, respectively. A second infrared sensor is mounted inside the spray rail 435 for accurately detecting the position of the film tail. The rotary pressing plate 438 is mounted on the fixed support 437, and is controlled to rotate by a third rotary driver 439 for adjusting the position and pressing the film tail.
When the winding drum 1 moves on the guiding blanking rail 4, the control system starts the fourth linear driver 431 to enable the limiting blocking block 432 to extend, so that the winding drum 1 is blocked from moving continuously, and the winding drum 1 is ensured to stay above the driving wheel 433. Subsequently, the second rotary driver 434 is activated to rotate the driving wheel 433 in the normal direction, thereby rotating the spool 1. Rotation of the spool 1 adjusts the position of the tail of the wound film to gradually approach the suction spray rail 435. The vision detector 436 monitors the position of the film tail in real time and when it is detected that the film tail is moving to a designated position, the control system instructs the drive wheel 433 to rotate in a reverse direction, and the spool 1 rotates in a reverse direction therewith, extending the film tail down into the suction and spray rail 435. After the second infrared sensor detects that the tail part of the film enters the adsorption spraying rail 435, the adsorption pipeline is started immediately, and the tail part of the film is adsorbed and positioned through the adsorption pipeline, so that the film is ensured to be kept stable in the spraying process. After the adsorption pipeline is started, the spraying pipeline sprays adhesive to the tail part of the film. After the spraying is finished, the adsorption pipeline and the spraying pipeline stop working, the driving wheel 433 is started again, and the winding drum 1 is driven to rotate forward, so that the tail part of the film is wound. At the same time, the third rotary actuator 439 controls the rotary pressing plate 438 to rotate the adjustment position so as to collide with the outer wall of the wound film. The pressing plate 438 is rotated to apply proper pressure to the film tail, so that the glued film tail is tightly attached to the outer wall of the film roll, and the rolling effect with neat edges is achieved. After the film tail is attached, the parts are reset, the limiting and blocking block 432 is retracted, the driving wheel 433 stops rotating, and the pressing plate 438 is rotated to adjust the initial position. The next reel 1 treatment and film tail fitting operation are prepared, and the continuity and the high efficiency of the whole winding process are ensured.
