Description

A kind of creasing machine head for coaming box coaming

technical field

The invention relates to manufacturing equipment for plastic turnover boxes, and in particular to a machine head of a special crease processing machine for coaming boards of coaming boxes. The machine head is the main processing head part of the crease processing machine.

Background technique

In the process of wholesale and retail of goods, a kind of coaming box is often used. The so-called coaming box, the specific structure is shown in Figure 9, and is made up of a tray 1, a loam cake 2 and a coaming panel 3, and the coaming panel 3 forms four side walls between the tray 1 and the loam cake 2; The board 3 is made of a plastic hollow board surrounded by butt joints. The coaming board 3 is specifically composed of two parallel and opposite fixed board parts and two parallel and opposite folded board parts. The first crease 4; the middle part of the two folded plate parts is also provided with a second crease 5 arranged along the longitudinal direction. During transportation and storage of an empty box, the hoarding 3 can be folded and stored between the tray 1 and the upper cover 2, which is very convenient to use.

In the field of plastic turnover boxes, the creases of hollow boards are usually made by scoring lines, that is, a line is carved at the creases. This kind of manufacturing equipment and technology is widely used in thin-walled light hollow boards. There are many, but the engraved lines will greatly reduce the strength of the box body, and a major feature of the above-mentioned coaming box is the high load-bearing requirement, and the coaming panels are all made of thick three-layer composite hollow boards (see Figure 10). It can be said that the line method is not suitable for making creases. In addition, people will also think of pressing the creases by hot pressing, but the current hot-pressing crease equipment is developed for real plastic boards, and is used to process thick three-layer composite hollow boards such as coaming boxes , it is easy to damage the surface of the board, and the production quality is poor.

Therefore, in the market, there is an urgent need to develop special hot-press crease equipment for the characteristics of the coaming board.

As shown in Fig. 11, a total of six creases on the two folded plate parts on the panel 3 to be processed are marked as A, B, C, D, E, F in sequence.

The coaming box coaming creasing machine using the machine head of this embodiment includes a machine base 6 with a working table 7 on which a feeder for feeding the coaming board is arranged. Mechanism 8, the feeding mechanism 8 horizontally feeds the coaming plate along the length direction of the working table 7, and three machine heads are arranged in sequence along the feeding direction of the feeding mechanism 8 on the working table 7: the front machine head 9, Middle nose 10, rear nose 11. The front nose 9, the middle nose 10, the rear nose 11 correspond to the three creases A, B, and C to be processed on the folded plate portion of the panel 3. Front nose 9, middle nose 10, rear nose 11 all adopt the structure of above-mentioned present embodiment nose.

In this embodiment, the machine head presses dents on both the upper surface and the lower surface of the panel 3, that is, double-sided creases. This crease is more flexible and convenient to bend, and it is easier to locate after folding, and will not bounce off by itself. .

When the creasing machine of this embodiment is used to work, the workers first insert the panel 3 to be processed horizontally between the upper and lower bearing bodies 20 and the upper pressing block 19 of the rear-end clamping device 8b, and the end of the panel 3 Pass through the three heads 9, 10, 11 between the upper and lower carriers 20 of the front clamping device 8a and the upper pressing block 19, and lean against the positioning action surface 24 of the backing 23 to complete the feeding; then, start In the creasing machine of this embodiment, the clamping drive mechanism 22 of the front clamping device 8a and the rear clamping device 8b both act to press down the upper pressing block 19 to clamp the two ends of the panel 3; then, The linear drive mechanism starts, and the feeding mechanism 8 feeds the panels of the coaming 3, so that the positions of the three creases A, B, and C to be processed on the panels of the coaming 3 are sent to the three machine heads 9, 10, and 11. First align the positions of the three creases A, B, and C of the panel 3 with the heating stations on the machine heads 9, 10, and 11, and start the pressure knife device set from top to bottom toward the crease machine work surface 7 The hydraulic cylinder 15 of 13 controls the pressure so that the front pre-pressing plate 28 and the rear pre-pressing plate 29 are pressed down on the panel 3 of the coaming, but the pressing tool mold 16 does not touch the panel of the coaming 3. At this time, the heating body driving mechanism 32 Lower the heating body mounting base 31 close to the panel 3, and at the same time, the heating body 17 is energized to work. After heating and baking the upper and lower sides of the crease position of the panel 3 for a certain period of time, the heating body driving mechanism 32 will turn the heating body The mounting base 31 moves up and resets, and the feeding mechanism 8 moves the positions of the three creases A, B, and C of the panel 3 to be processed to the molding stations on the machine heads 9, 10, and 11, and starts all the hydraulic cylinders 15 , the hydraulic cylinder 15 drives the press knife mold 16 to press down, and the press knife mold 16 presses the creases on the upper surface and the lower surface of the panel 3, so as to complete the A, B, and C creases at the same time, and the hydraulic cylinder 15 completely Return to reset; then, the feeding mechanism 8 sends the other folded part of the panel 3 to the three heads 9, 10, 11, and performs the other three creases D, E, and F in the same manner as above. At last, the manual cutting by the workers has completed the making of six creases on the whole coaming box coaming 3.

The front pre-press plate 28 and the rear pre-press plate 29 of the above-mentioned embodiment are arranged on the press knife mounting plate 27 together with the press knife mold 16. This is an example. In practice, the pre-press plate and the rear pre-press plate can also be set separately, as follows: The knife pressing device also includes a front preloading mechanism and a rear preloading mechanism, the front preloading mechanism includes a front preloading plate and a front preloading plate driving mechanism, and the rear preloading mechanism includes a rear preloading plate and a rear preloading plate driving mechanism; the front preloading plate The front and rear pre-compression plates are long strips along the width direction of the worktable, and they are arranged one after the other on the front and rear sides of the press tool mold; the front pre-compression plate and the rear pre-compression plate are both facing the worktable from top to bottom , and relative to the frame body, slidingly connected in the up and down direction, the front pre-compression plate driving mechanism acts on the front pre-compression plate, and the rear pre-compression plate driving mechanism acts on the rear pre-compression plate.
