Description

Technical Field

[0001] The utility model relates to a heat sealing device, in particular to a heat sealing device for processing transfer bags, belonging to the technical field of transfer bag processing. Background Art

[0002] A transfer bag is a packaging bag specially designed for transferring goods during the logistics process. The transfer bag may need to be heat-sealed during the production process. Heat sealing is a common packaging technology that fuses the edges of plastic film or composite materials together by heating to form a closed package.

[0003] After searching, a Chinese patent with publication number CN202420295186.7 discloses a packaging bag heat sealing mechanism, which includes a frame, and two stabilizing components are installed on the top of the frame, and the stabilizing components are used to stabilize the heat sealing part of the packaging bag.

[0004] The above existing technology is equipped with a telescopic cylinder. When the telescopic end of the telescopic cylinder moves downward, the telescopic end of the telescopic cylinder can drive the support plate in the stabilizing assembly to move downward. When the rolling sleeve contacts the packaging bag on the top of the frame, the rolling sleeve generates friction with the packaging bag under the action of external force, causing the rolling sleeve to roll on the surface of the packaging bag, so that the two rolling sleeves can tighten and straighten the packaging bag area at the bottom of the heat sealing plate, thereby increasing the stability of the heat sealing area of ​​the packaging bag, thereby facilitating the heat sealing work of the heat sealing plate on the packaging bag.

[0005] However, in actual use, when the heat sealing plate heat seals the transfer bag, due to temperature reasons, the heat sealing plate may stick during the heat sealing process. When the lower side is heat sealed, the residual material will cause adhesion during the next heat seal. The residue may cause the new seal to be uneven or incomplete, affecting the sealing and protective performance of the package, resulting in a decrease in sealing quality. To this end, we provide a heat sealing device for transfer bag processing to solve the above problems. Utility Model Content

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] like Figure 1-6 As shown, the utility model provides a technical solution, a heat sealing device for processing transfer bags, including a base plate 1, a heat sealing frame 2 is fixedly connected to the upper side of the base plate 1, an electric telescopic rod 3 is fixedly connected to the upper side of the inner wall of the heat sealing frame 2, an output end of the electric telescopic rod 3 is fixedly connected to a U-shaped frame 4, the inner wall of the U-shaped frame 4 is rotatably matched with a heating ring 5, the inner wall of the heating ring 5 is fixedly connected to a heating wire 6, and one side of the inner wall of the heating ring 5 is fixedly connected to a heat sealing plate 7.

[0027] An electric slide rail 8 is fixedly connected to the upper side of the inner wall of the U-shaped frame 4, and a scraper 9 that cooperates with the heat sealing plate 7 is slidably fitted on the electric slide rail 8. Gears 10 are provided at both ends of the heating ring 5. Linkage components 11 that cooperate with the gears 10 are provided on both sides of the U-shaped frame 4, and a cooling component 12 is provided on the upper side of the bottom plate 1.

[0028] The linkage assembly 11 includes movable openings 111 on both sides of the inner wall of the U-shaped frame 4, a moving block 112 that slides on the inner wall of the movable opening 111, an L-shaped toothed plate 113 fixedly connected to one side of the moving block 112 and meshing with the gear 10, and a return spring 114 fixedly connected to the moving block 112 and the inner wall of the movable opening 111. When the U-shaped frame 4 moves downward, it first meshes with the L-shaped toothed plate 113 to drive the heating ring 5 to flip. After flipping to a certain angle, the gear 10 will resist the lower side of the inner wall of the L-shaped toothed plate 113, and then press the L-shaped toothed plate 113 and the U-shaped frame 4 downward at the same time, and the moving block 112 moves in the movable opening 111. When it is completed, the moving block 112 is reset by pressing the return spring 114.

[0029] The cooling assembly 12 includes a heat dissipation frame 121 fixedly connected to the base plate 1 and located on one side of the heat sealing frame 2, an installation port 122 opened on the upper side of the heat dissipation frame 121, and multiple fans 123 arranged on the inner walls of multiple installation ports 122. By starting the fans 123 in the installation ports 122 to blow from top to bottom, air can be blown to the transfer bag moving on the upper side of the base plate 1, thereby accelerating the heat dissipation effect.

[0030] An extension frame 13 is fixedly connected to one side of the base plate 1, and a cylinder 14 is fixedly connected to the upper side of the inner wall of the extension frame 13. The output end of the cylinder 14 is fixedly connected to a lower pressure plate 15. One side of the lower pressure plate 15 is rotatably engaged with two lower pressure rollers 16. The cylinder 14 presses the lower pressure plate 15 and the lower pressure roller 16 downward, so that the lower pressure roller 16 can fit the transfer bag on the base plate 1.

[0031] A winding plate 17 is fixedly connected to the upper side of the bottom plate 1 and on one side of the cooling component 12. A winding motor 18 is fixedly connected to one side of the winding plate 17. A sleeve roller 19 is fixedly connected to the output end of the winding motor 18. The transfer bags can be collected by putting the winding roller on the sleeve roller 19 and slowly rotating the winding motor 18.

[0032] The inner wall of the movable opening 111 is fixedly connected to the limit rod 20 , and the moving block 112 is slidably fitted on the outer side of the limit rod 20 . When the moving block 112 moves up and down, the limit rod 20 can limit the moving block 112 and the return spring 114 at the same time.

[0033] A protective net 21 is fixedly connected to the upper side of the heat dissipation frame 121. The protective net 21 is located on the upper side of the multiple fans 123. The protective net is convenient for protecting the upper side of the fans 123 when they rotate to avoid accidental injury to personnel.

[0034] When the utility model is in use: first, the transfer bag to be heat-sealed is laid flat on the upper side of the bottom plate 1, and the other end is wrapped around the outer side of the sleeve roller 19 through the external winding roller. By starting the winding motor 18, the sleeve roller 19 is driven to slowly wind up, so as to pull the transfer bag to move. During the movement, the cylinder 14 on the extension frame 13 presses the lower pressure plate 15 and the lower pressure roller 16 downward to flatten the transfer bag laid on the bottom plate 1;

[0035] The heating wire 6 is started in advance to preheat, and the electric telescopic rod 3 is started to press the U-shaped frame 4 downward. During the downward squeezing process, the gear 10 will mesh with the L-shaped toothed plate 113, causing the heating ring 5 to flip over. When the heat sealing plate 7 is facing downward, it will no longer rotate. Then the return spring 114 is squeezed downward to make the moving block 112 move downward in the movable opening 111 without restricting the downward movement of the U-shaped frame 4. The heat sealing plate 7 with its head down contacts the transfer bag to achieve heat sealing. When the heat sealing is completed, the U-shaped frame 4 contracts and resets. Under the action of the L-shaped toothed plate 113 on the gear 10, the heat sealing plate 7 is again turned upward and is level with the scraper 9. Then the electric slide rail 8 is started to drive the scraper 9 to move, which can clean the upper side of the heat sealing plate 7, so that the residue on the heat sealing plate 7 is cleaned, thereby maintaining consistent sealing quality in each processing and improving subsequent sealing quality.

[0036] After sealing, the fan 123 on the heat dissipation frame 121 is started to guide the air so that it blows downward, thereby quickly cooling the heat-sealed transfer bag part, reducing the possibility that the seal may not be completely solidified, which may cause the seal to open or deform during the winding process, reducing the situation that affects the sealing of the packaging, and improving the stability of the seal.
