Description

Swing bar circular loom

technical field

The utility model relates to plastic woven bag processing equipment, in particular to a swing rod type circular loom which can save more than 10,000 kWh of electricity and more than 300 yuan in annual consumption.

Background technique

The general structure of the circular loom in the past is to use a drum-shaped cam to drive the slider to move up and down. The prime mover motor needs 4 kilowatts to start the operation through the V-belt transmission. Later, the planar cam was used, and the host motor also needed 2.2 kilowatts to start running. Because the transmission device of the main machine motor uses a pulley structure, it must have tension to run, and a part of the power of the motor will be consumed to overcome the tension of the pulley. In addition, the upper end of the original pendulum rod was fixed with a copper sleeve, and the connecting parts on the heald belt moved up and down in the copper sleeve 160 times per minute. It was damaged in about half a year at most, and the entire pendulum rod had to be replaced during maintenance. A circular loom has more than 30 pendulum rods, and it takes a lot of work to disassemble and assemble, often taking a day. Moreover, the old pendulum rods are discarded, and the replacement price is high.

Utility model content

The purpose of this utility model is to provide an energy-saving pendulum-type circular loom aiming at the above defects.

The technical scheme of the utility model is a swing rod type circular loom, which includes a warp wire rack, a warp wire conveying device, a main machine and a cloth rolling device. Ring, upper door ring, size ring, gate, ring ring, heald belt, separation bracket, shuttle propulsion mechanism, swing rod, copper sleeve and swing rod seat, it is characterized in that the said main engine transmission device is a gear transmission structure; The surface of the copper sleeve on the said swing rod is a corrugated knurled shape and a transition fit with the end of the swing rod.

Said gear transmission structure is that a driving gear is installed on the output shaft of the motor and is engaged with a passive gear transmission mounted on the main engine main shaft; said motor is a 1.5 kilowatt variable frequency motor.

The utility model has the advantage of adopting the gear transmission structure of the main engine, without the tension force of the belt pulley transmission, and reducing the burden on the motor, so that the motor can run the main engine with only 1.5 kilowatts, and each circular loom can produce 20 hours a day, saving 2 hours per hour. The annual electricity saving is more than 10,000 kWh. There are about 100,000 plastic weaving circular looms in the country, which can save 1.2 billion kWh of electricity when popularized. Because the surface is corrugated and knurled copper sleeves, the copper sleeves are damaged. , as long as you use the special pliers for copper sleeves, you can replace the copper sleeves in only 2 minutes, which saves labor and time, and makes the pendulum rods interchangeable for dozens of times, reducing the waste of pendulum rods and saving costs. One copper sleeve is One-tenth the price of a pendulum. The utility model is made to be an energy-saving and consumption-reducing product.

Detailed ways

The embodiments are further described below in conjunction with the accompanying drawings.

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, 1-warp wire rack, 2-warp wire conveying device, 3-main machine, 4 cloth rolling device, 301-motor, 302-driving gear, 303-passive gear, 304 -Frame, 305-chassis, 306-spindle seat, 307-spindle, 308-plane cam, 309-lower door ring, 310-upper door ring, 311-size ring, 312-gate, 313-ring ring, 314 -Heald belt, 315-separation bracket, 316-shuttle propulsion mechanism, 317-fork, 318-copper sleeve, 319-fork seat. As shown in the figure, the utility model is improved on the basis of the original swing rod type circular loom structure. Specifically, the pulley transmission device of the main engine is improved to a gear transmission structure, and the driving gear 302 is installed on the output shaft of the main engine motor 301 to drive and mesh with the driven gear 303 on the main shaft 307. After such improvement, the pulley and the necessary tension force are omitted. , to reduce the burden on the motor, as long as the original 4 kW motor is replaced by a 1.5 kW variable frequency motor, the energy saving is remarkable; in addition, the copper sleeve 318 on the swing rod 317 is made into a corrugated knurled shape embedded in the end of the swing rod 317 For the transition fit, change the fastening connection in the past, so that when the copper sleeve 318 is damaged, it can be easily replaced with special pliers. There are more than 30 pendulum bars on a circular loom, and it only takes about one hour to replace the copper sleeve, which greatly saves man-hours and shortens downtime, and the price of replacing a copper sleeve is only one tenth of the price of the entire pendulum bar. One, significant reduction in consumption. Moreover, the swing rod can be used continuously, and the number of times to replace the copper sleeve can reach dozens of times.
