[0028] This embodiment provides a plastic bubble shell folding device, the top frame 100 and the bottom frame 200 are both fixedly arranged;

[0029] The lifting cylinder 1 is fixed on the top frame 100, and the lifting frame 300 is fixed on the lower end of the piston rod of the lifting cylinder 1. The lifting cylinder 1 can drive the lifting frame 300 to move up and down; the lifting frame 300 also includes a heating knife fixing plate 4, a heating knife spacing adjustment screw 2, and a heating knife 6; the heating knife spacing adjustment screw 2 is rotatably connected to the lifting frame 300 body, and the heating knife spacing adjustment screw 2 is threadedly connected to the left and right heating knife fixing plates 4. The heating knife spacing adjustment screw 2 is rotated to adjust the two heating knife fixing plates 4 to move away from or close to each other to adapt to the size of the plastic workpiece; a total of three heating knives 6 are arranged, and two of the heating knives 6 are fixedly arranged under the opposite heating knife fixing plates 4; the lifting and lowering of the lifting frame 300 drives the heating knife 6 to move up and down;

[0030] The positive and negative thread screw module 14 is fixed to the bottom frame 200, and the left and right folding module bottom plates 26 are respectively threadedly connected with the positive and negative thread parts of the positive and negative thread screw module 14; thus, the left and right folding module bottom plates 26 are moved away from or closer to each other by rotating the screw of the positive and negative thread screw module 14;

[0031] The linear guide slider 10 and the guide shaft 11 form a linear sliding module, and two linear sliding modules are provided, wherein the guide shaft 11 is fixed to the bottom frame 200, and the linear guide slider 10 is fixed to the bottom plate 26 of the folding module, so that when the positive and negative screw rod module 14 drives the left and right bottom plates 26 of the folding module to move, the linear sliding module has the function of supporting and guiding the two bottom plates 26 of the folding module;

[0032] The product backing 7 is located above the bottom plate 26 of the folding module, and each product backing 7 is fixedly connected to a bottom plate 26 of the folding module through a backing fixing member; the product backing 7 is used to limit the left and right positions of the plastic workpiece (product);

[0033] The product support plate 18 is located between the left and right folding module bottom plates 26. The product support plate 18 is fixed on the product support plate main beam 24. The product support plate main beam 24 is fixed to the bottom frame 200 through the positive and negative threaded screw module 14 and the guide shaft 11. A folding plate 9 is provided on both sides of the product support plate 18.

[0034] There are two folding cylinders 13 in total, and folding cylinder fixing plates 30 are respectively fixed on the left and right folding module bottom plates 26. The two folding cylinders 13 are respectively fixed on the folding cylinder fixing plates 30. The telescopic rods of the folding cylinders 13 are fixedly connected to the folding plates 9. The folding cylinders 13 are used to drive the folding plates 9 away from and close to the product pallet 18.

[0035] The present embodiment provides a plastic bubble shell folding device, and its working principle is as follows: when the product 19 is placed on the product support plate 18, the left and right sides of the product 19 are limited by the left and right product backrests 7; the lifting cylinder 1 drives the lifting frame 300 to descend, heats the side of the product 19, and makes the side of the product 19 bend downward along the side of the product support plate 18; the lifting frame 300 moves upward; the folding cylinder 13 drives the folding plate 9 to approach and bend the side of the product 19.

[0036] To summarize, the positive and negative thread screw module 14 is fixed to the bottom frame 200, and the left and right folding module bottom plates 26 are respectively threadedly connected to the positive and negative thread parts of the positive and negative thread screw module 14, and each product backing 7 is fixedly connected to a folding module bottom plate 26, so that rotating the hand wheel 31 drives the screw of the positive and negative thread screw module 14 to rotate so that the left and right folding module bottom plates 26 move away from or closer to each other, that is, the two product backings 7 move away from or closer to each other at the same time, thereby achieving the effect of adjusting the synchronous movement of the two product backings 7 (equivalent to the existing design limit plate) at one time.

[0037] Furthermore, a product entry guide plate 8 is provided at one end of the product support plate 18 for entering the product 19, and the end of the product entry guide plate 8 away from the product support plate 18 is tilted upward, which is conducive to the smooth entry of the deformed product.

[0038] Furthermore, the mounting hole of the backrest fixing piece is a waist-shaped hole, which can be conveniently used to fine-tune the front-to-back and up-and-down clearances.

[0039] Furthermore, a third heating knife 6 is arranged at the bottom front end of the lifting frame 300; a front folding backrest 20 is fixedly arranged at the front end of the bottom frame 200, and the front folding backrest 20 is used to limit the front position of the product 19; the front folding cylinder 22 is fixed to the bottom frame 200; the front folding cylinder 22 drives the front folding plate 17 to approach or move away from the product support plate 18, so the front side of the product 19 can be folded.

[0040] Furthermore, a fiber optic sensor 25 is arranged at one end where the product enters the bottom frame 200, and the fiber optic sensor 25 is fixed on one side of the product backrest 7. The fiber optic sensor 25 is used to detect whether there is a product entering; the material blocking cylinder 23 is used to drive the material blocking limit plate 21 to rise and fall, and the material blocking limit plate 21 is arranged between the front folding plate 17 and the left and right folding plates 9. When the material blocking limit plate 21 is in the high position of the lifting, the material blocking limit plate 21 is used to limit the front end position of the product 19; the fiber optic sensor 25 transmits the signal to the controller, and the controller controls the action of the material blocking cylinder 23.

[0041] During the conveying process, the guide plate 8 and the backrest 7 are used as guides to ensure that the product does not deviate. After the product is delivered to the position where the optical fiber 25 is located, the optical fiber 25 detects the arrival of the product, and the material blocking cylinder 23 starts to rise, and the material blocking plate limit plate 21 is used to block the product limit, so that the product has an accurate longitudinal position; the distance from the optical fiber 25 to the limit plate 21 is pushed synchronously by a pusher device in the previous process; after the product is in place, the heating knife 6 is pressed down to the left and right and front of the product with the assistance of the lifting cylinder 1 and the lifting frame 3, and after the product is heated and softened, the left and right folding plates 9 and the front folding plate 17 are pushed inward to bend the product, and then air is blown to cool and shape the product.

[0042] The prior art does not have this front-end positioning function, and its positioning of the product is inaccurate; the present application adds a material blocking cylinder 23 and a material blocking limit plate 21 to limit the position of the front side of the product (the prior art cannot synchronously open and close the left and right folding modules, and the present application adds positive and negative screws to achieve this function, making product positioning more accurate and workers' operation more convenient and quick).

[0043] Furthermore, the front folding slider 28 is slidably matched with the front folding guide rail 29, and the front folding guide rail 29 is fixed to the bottom frame 200; the front folding slider 28 is fixed to the front folding plate.

[0044] Furthermore, the linear motion guide rod 5 is vertically fixed and slides through the lifting frame 300 .

[0045] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
