Description

Technical Field

[0001] This utility model relates to the field of composite device technology, specifically a composite device for plastic GAG sheets with pressure regulation function. Background Technology

[0002] Plastic GAG sheet is a three-layer co-extruded composite sheet, produced by co-extruding an intermediate layer of APET and two layers of PETG raw materials in a suitable ratio. This sheet is particularly suitable for packaging boxes that require high-frequency heat sealing and adhesive bonding, and has advantages such as good transparency, high impact resistance, excellent rigidity, and environmental recyclability. In the production process of plastic GAG sheet, the three-layer composite material needs to be pressed together. However, the pressure of traditional pressing devices is mostly fixed, which makes it inconvenient to adjust the pressing pressure. To improve this situation, a composite device for plastic GAG sheet with pressure adjustment function is proposed.

The chassis has an installation chamber isolated from the outside. A first motor is fixedly welded to the top wall of the installation chamber. A transmission shaft is rotatably connected to the top wall of the chassis. The output shaft of the first motor is coaxially connected to the transmission shaft. A turntable is fixedly welded to the top of the transmission shaft. Support seats are symmetrically welded to both sides of the top wall of the chassis. An inner support shaft is rotatably connected to each of the two support seats. A pulley is fixedly sleeved on each of the two inner support shafts. Both pulleys are in contact with the bottom wall of the turntable. A bracket is provided above the chassis.

[0004] Although it enables the pressing plate to more accurately press the two parts of the composite plastic sheet together, thus improving the pressing success rate;

[0005] However, the existing composite device does not solve the problem that it is not convenient to use for linkage, centering, clamping and fixing of multi-layer plastic GAG sheet raw materials and plugging and disassembling pressure plates of different sizes. It is not conducive to flexible pressure adjustment and lamination processing of multi-layer plastic GAG sheets and to adapting lamination processing of plastic GAG sheets of different sizes, thus affecting the flexibility of use.

This is not conducive to flexible pressure adjustment and lamination of multi-layer plastic GAG sheets and to adapting and laminating plastic GAG sheets of different sizes, thus affecting the flexibility of use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a composite device for plastic GAG sheets with pressure regulation function, comprising a support base and a stepper motor.

The stepper motor 6 is installed at the center of the support base 1 and serves as a power drive. A drive shaft 7 is installed at the output end of the stepper motor 6. Three sets of drive arms 8 are equally spaced on the surface of the drive shaft 7. A linkage arm 10 is provided at the end of each drive arm 8 away from the drive shaft 7. A hinge shaft 9 is provided at the end of each linkage arm 10 close to the drive arm 8. The linkage arm 10 is movably connected to the drive arm 8 through the hinge shaft 9. A clamping block 11 is provided at the end of each linkage arm 10 away from the drive arm 8. The clamping block 11 is movably connected to the linkage arm 10. Three sets of arc grooves 12 are equally spaced on the surface of the support base 1. The clamping block 11 is slidably connected to the arc groove 12. Support columns 2 are symmetrically installed at the top of the support base 1. A support plate 3 is provided above the support base 1 and is fixedly connected to the support column 2.

[0025] A hydraulic cylinder 4 is installed at the top of the bearing plate 3. The hydraulic cylinder 4 plays a power driving role, and a push arm 13 is installed at the output end of the hydraulic cylinder 4.

[0026] Circular multi-layered plastic GAG sheets are stacked sequentially on the support base 1. Stepper motor 6 is turned on, and the stepper motor 6 drives three sets of drive arms 8 to rotate synchronously via drive shaft 7. Drive arms 8 drive linkage arms 10 to rotate via hinge shaft 9. With the sliding engagement of clamping blocks 11 and arc-shaped grooves 12, the linkage arms 10 drive clamping blocks 11 to slide inside the arc-shaped grooves 12. The three sets of clamping blocks 11 slide synchronously towards the center position. With the cooperation of the three sets of clamping blocks 11, the multi-layered material is centrally clamped and fixed on the support base 1. Then, hydraulic cylinder 4 is turned on, and hydraulic cylinder 4 drives push arm. 13 moves downward, and the push arm 13 drives the plug seat 14, plug post 15 and pressure plate 5 to move downward and make the pressure plate 5 contact the raw material. Under the continuous action of the hydraulic cylinder 4, the pressure plate 5 continuously presses the raw material to complete the composite production process of plastic GAG sheet. When it is necessary to adjust the pressing pressure, the stroke of the push arm 13 can be adjusted by controlling the hydraulic cylinder 4. The larger the stroke of the push arm 13, the greater the pressure. This realizes convenient linkage, centering, clamping and fixing of multi-layer plastic GAG sheet raw material, which facilitates flexible pressure adjustment and composite processing of multi-layer plastic GAG sheet.

[0027] A plug-in seat 14 is installed at the bottom end of the push arm 13, and limit rings 17 are symmetrically installed on the side wall of the plug-in seat 14.

[0030] When processing plastic GAG sheets of different sizes, it is necessary to replace the pressure plate 5 with a different size. Pull out the limiting post 16, and the limiting post 16 slides inside the limiting ring 17. The limiting post 16 drives the ring 20 to move and the ring 20 squeezes the spring 18, so that the limiting post 16 moves away from the plug post 15 and disengages from the limiting groove 19. The plug post 15 can then be pulled out from the plug seat 14, and the pressure plate 5 can be removed. Then, replace the pressure plate 5 with a pressure plate of a different size and repeat the above operation to install it into the plug seat 14. Then, with the cooperation of the clamping block 11, the composite processing of plastic GAG sheets of different sizes can be completed. This realizes the convenient plugging and disassembling of pressure plates of different sizes, which facilitates the adaptation and composite processing of plastic GAG sheets of different sizes and improves the flexibility of use.

[0031] Working Principle: Circular multi-layered plastic GAG sheets are stacked sequentially on the support base 1. A stepper motor 6 drives three sets of drive arms 8 to rotate synchronously via a drive shaft 7. The drive arms 8, via a hinge shaft 9, drive the linkage arm 10 to rotate. With the sliding engagement of the clamping block 11 and the arc-shaped groove 12, the linkage arm 10 drives the clamping block 11 to slide inside the arc-shaped groove 12. The three sets of clamping blocks 11 slide synchronously towards the center position, thus centrally clamping and fixing the multi-layered material onto the support base 1. A hydraulic cylinder 4 drives the push arm 13 to move downwards. The push arm 13 drives the insertion seat 14, insertion post 15, and pressure plate 5 to move downwards, bringing the pressure plate 5 into contact with the material. Under the continuous action of the hydraulic cylinder 4, the pressure plate 5 continuously presses against the material, completing the composite processing of the plastic GAG sheets. When the pressing pressure needs to be adjusted, it is... The stroke of the push arm 13 can be adjusted by controlling the hydraulic cylinder 4. The greater the stroke of the push arm 13, the greater the pressure. When processing plastic GAG sheets of different sizes, it is necessary to replace the pressure plate 5 of different sizes. Pull the limiting post 16 outward. The limiting post 16 slides inside the limiting ring 17. The limiting post 16 drives the ring 20 to move and the ring 20 squeezes the spring 18, so that the limiting post 16 moves away from the plug post 15 and disengages from the limiting groove 19. The plug post 15 can then be pulled out from the plug seat 14. The pressure plate 5 can be removed. Then, replace it with a pressure plate 5 of other sizes and repeat the above operation to install it into the plug seat 14. Then, with the cooperation of the clamping block 11, the composite processing of plastic GAG sheets of different sizes can be completed. The above is the complete usage of the composite device for plastic GAG sheets with pressure adjustment function.
