Description

Technical Field

[0001] The utility model belongs to the technical field of plastic processing, and particularly relates to an automatic plastic pressing device. Background Art

[0002] Plastic is a polymer compound made from monomers through polyaddition or polycondensation reactions. It has a medium deformation resistance, between that of fiber and rubber. It is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. The main component of plastic is resin. Resin refers to a polymer compound that has not yet been mixed with various additives. The term resin was originally named after the lipids secreted by animals and plants. During the packaging process of plastic products, due to the large expansion of the plastic parts themselves, they need to be compressed using a compression device. During the compression process, the plastic products are packaged and bundled. The compression device in the existing technology uses a compression plate for compression. The size of the compression plate is fixed. Therefore, when the size of the plastic products is inconsistent, the compression plate needs to be replaced, which affects the compression molding efficiency and reduces the packaging speed.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] This specific embodiment is an automatic compression molding device, and its structural diagram is as follows Figure 1 As shown, it includes a support platform 1, a clamping mechanism 5, and a side frame 4. The bottom of the support platform 1 has a base plate 2, and the upper surface of the support platform 1 is provided with multiple suction ports 3. The side frames 4 are fixed on the upper surface of the base plate 2 and are symmetrically distributed in two groups on both sides of the support platform 1. The two groups of side frames 4 are movably installed with a clamping mechanism 5.

[0024] Reference Figure 2 The clamping mechanism 5 includes a support beam 6, a lifting plate 10, and a pressure rod 13. There are two groups of lifting plates 10 symmetrically distributed on both sides of the support beam 6. A movable groove is provided on each of the two groups of lifting plates 10. A movable block 8 is slidably embedded in the movable groove. Slide blocks 7 are protruding from the two ends of the support beam 6. The movable blocks 8 are symmetrically distributed in pairs in the movable groove. The bottom end surface of the movable block 8 is rotatably connected to the rotating shaft 12, and the pressure rod 13 is rotatably installed below the rotating shaft 12. A rotating groove is provided at the connection between the end of the pressure rod 13 and the rotating shaft 12, and the end of the rotating shaft 12 penetrates into the rotating groove. There are two groups of pressure rods 13 below the lifting plate 10 and they are distributed in a V shape. The ends of the pressure rods 13 away from the rotating shaft 12 are rotatably connected to each other. A drive motor 11 is fixedly installed at the end of the lifting plate 10. A screw 9 is connected to the output shaft of the drive motor 11. The screw 9 is rotatably embedded in the movable groove, and the screw 9 is threadedly connected to the movable block 8.

[0025] Reference Figure 1 、 Figure 3 The inner wall of the side frame 4 is vertically provided with an inverted guide groove 14 for the slider 7 to slide into. A telescopic cylinder 15 is vertically fixedly installed inside the guide groove 14. The telescopic end of the telescopic cylinder 15 is fixedly connected to the slider 7.

[0026] Reference Figure 4 The suction ports 3 are evenly spaced on the upper surface of the support platform 1, and the air cavity 16 is connected to the suction ports 3. The support platform 1 has an air cavity 16 inside, and a fan 17 is installed inside the air cavity 16.

[0027] Working principle: when in use, first place the packaging tape for wrapping plastic products on the support table 1, then place the stacked plastic products that need to be packaged on the support table 1, and start the fan 17. The fan 17 performs suction, and the generated suction force is emitted from the suction port 3 to adsorb the bottom of the stacked plastic products. Then, the opening angle of the pressure rod 13 is adjusted according to the size of the plastic products, and the driving motor 11 is started. The motor screw 9 of the driving motor 11 rotates, and the threads on the outer wall of the screw 9 are set in opposite directions. Then, in the process of rotation of the screw 9, the two sets of relatively distributed moving blocks 8 are relatively close to each other, and the rotating shaft 12 at the bottom moves synchronously with the moving block 8, and then the V-shaped pressure rod 13 is relatively close to or away from each other. After adjusting the spacing, the telescopic cylinder 15 contracts, driving the slider 7 to slide vertically along the guide groove 14. The pressure rod 13 is forced to drop in height and approach the plastic product to press the plastic product. Then, the packaging tape for wrapping the plastic can be wrapped around the plastic product to bundle it, and the wrapping operation is completed.

[0028] Then the telescopic cylinder rises, driving the pressure rod 13 to rise, and the pressure rod 13 gradually leaves the upper surface of the plastic product, thus completing the packaging of a group of products. Then the fan 17 is turned off, and the suction at the suction port 3 is removed, and the bundled plastic products can be removed and new products can be placed. The plastic products can be foam boards, plastic belts, etc.

[0029] All technical features in this embodiment can be freely combined according to actual needs.
