Description

Technical Field

[0001] This utility model belongs to the field of heat sealing of inner lining bags, and in particular relates to a heat sealing mechanism for inner lining bags. Background Technology

[0002] During the heat sealing process of the inner lining bag, the top opening of the annular bag body needs to be heat sealed with the horizontal bag body. Before heat sealing, the horizontal bag body is placed on top of the annular bag body, and then the horizontal bag body covering the top opening of the annular bag body is cut to achieve partial assembly of the inner lining bag body. After the annular bag body is fixed, the horizontal bag body is placed on the annular bag body for heat pressing. During the heat pressing process, the horizontal bag body is not restrained and is prone to flipping under the airflow in the space, which affects the subsequent heat pressing. Summary of the Invention

[0003] In view of this, the present invention aims to propose a heat-sealing mechanism for inner lining bags to solve the technical problem that, after the annular bag body is fixed, the horizontal bag body is not restrained during the heat-sealing process, and is prone to flipping under the action of airflow in the space, which affects the subsequent heat-sealing.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A heat-sealing mechanism for inner lining bags includes a support platform and a heat-pressing assembly. The top of the support platform has an opening, and a sleeve ring is fixedly connected to the edge of the opening. Auxiliary pressure assemblies are fixedly installed on both sides of the top of the support platform.

[0006] The auxiliary pressure assembly includes a lower support body and an upper support body. The lower support body is fixedly connected to the top of the support platform, and the upper support body is rotatably connected to the end of the lower support body. An electromagnet is fixedly installed at the end of the lower support body, and a magnet block cooperating with the electromagnet is fixedly installed at the end of the upper support body. Multiple support rollers are rotatably connected to the upper surface of the lower support body and the lower surface of the upper support body.

[0007] Furthermore, the hot pressing assembly includes a support frame, a plurality of first electric cylinders are fixedly connected to the top of the support frame, and a movable platform is fixedly connected to the telescopic ends of the plurality of first electric cylinders after passing through the support frame. An annular hot pressing body is fixedly connected to the bottom of the movable platform.

[0008] Furthermore, the top of the moving platform is provided with a clearance opening, and an auxiliary support platform is fixedly installed on the top of the moving platform. The top of the auxiliary support platform is fixedly connected to the telescopic end of the second electric cylinder, which passes through the auxiliary support platform and is then fixedly connected to a mounting base. The bottom of the mounting base is fixedly installed with a first motor, and the output end of the first motor is fixedly connected to a rotating plate. Both ends of the rotating plate are fixedly installed with cutter heads.

[0009] Furthermore, an elastic telescopic rod is fixedly connected to the bottom of the rotating plate at the middle position, and a pressure head is fixedly connected to the bottom end of the elastic telescopic rod.

[0010] Furthermore, the bottom of the support platform is fixedly connected to two symmetrically arranged support legs, the bottom of each of the two support legs is slidably provided with a support rail, the ends of each of the two support rails are fixedly connected to a second motor, the output end of the second motor is fixedly connected to a threaded rod, the threaded rod passes through the support leg, and the threaded rod is threadedly connected to the support leg.

[0011] Furthermore, both ends of the bottom of the two support tracks are fixedly connected to a first support seat.

[0012] Furthermore, a second support base is fixedly connected to the bottom end of the support frame, and the second support base is erected above one of the first support bases.

[0013] Compared with the prior art, the heat-sealing mechanism for inner lining bags described in this utility model has the following advantages:

[0014] The present invention describes a flip-up upper support body, which drives multiple support rollers to press against the top surface of a horizontal bag. Then, an electromagnet attracts a magnetic block, magnetically positioning the upper and lower support bodies and pressing the horizontal bag in place. Before the hot pressing assembly, the horizontal bag is supported and stabilized. During the hot pressing process of the hot pressing assembly pressing the top of the horizontal bag and the vertical annular bag, the horizontal bag will thermally shrink, shrinking towards the hot pressing position. While the horizontal bag is pressed by the support rollers on the upper support body, it can move between the support rollers, providing freedom for the shrinkage of the horizontal bag.

[0015] In the process described in this utility model, during the contact of the blade with the horizontal bag, the pressure head will first press down on the horizontal bag. Then, during the process of the blade descending to cut the horizontal bag, the pressure head will pre-tension the horizontal bag to prepare for the cutting. Attached Figure Description

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] As 1 to Figure 7 As shown, in one embodiment, a heat-sealing mechanism for an inner lining bag includes a support platform 1 and a heat-pressing assembly. The top of the support platform 1 is provided with an opening 101, and a sleeve ring 2 is fixedly connected to the edge of the opening 101. Auxiliary pressure assemblies are fixedly installed on both sides of the top of the support platform 1.

[0031] The auxiliary pressure assembly includes a lower support body 3 and an upper support body 4. The lower support body 3 is fixedly connected to the top of the support platform 1, and the upper support body 4 is rotatably connected to the end of the lower support body 3. An electromagnet 5 is fixedly installed at the end of the lower support body 3, and a magnet block 6 that cooperates with the electromagnet 5 is fixedly installed at the end of the upper support body 4. Multiple support rollers 7 are rotatably connected to the upper surface of the lower support body 3 and the lower surface of the upper support body 4.

[0032] Specifically, the inner lining bag 8 includes a horizontal bag 801 and a vertical annular bag 802. During installation, the top of the vertical annular bag 802 is rolled up onto the top of the connecting ring 2, and then the horizontal bag 801 is laid horizontally on top of the vertical annular bag 802.

[0033] It should be understood that before hot pressing, the top of the vertical annular bag 802 is first rolled onto the top of the connecting ring 2, and then the horizontal bag 801 is laid horizontally on top of the vertical annular bag 802, with both ends of the horizontal bag 801 resting on the support rollers 7 above the two lower support bodies 3. Then, the upper support body 4 is flipped over, and the upper support body 4 drives multiple support rollers 7 to press onto the top surface of the horizontal bag 801. Then, the electromagnet 5 attracts the magnet block 6, magnetically positioning the upper support body 4 and the lower support body 3, thus placing the horizontal bag 801 in place. The flat bag 801 is pressed down. Before the hot pressing assembly, the horizontal bag 801 is supported and maintained to keep it stable. During the hot pressing process of the hot pressing assembly pressing the top of the horizontal bag 801 and the vertical annular bag 802, the horizontal bag 801 will shrink due to heat. The horizontal bag 801 will shrink towards the hot pressing position. While the horizontal bag 801 is pressed down by the support rollers 7 on the upper support body 4, it can move between the support rollers 7, which can provide the horizontal bag 801 with freedom of movement.

[0034] Such as 1 and Figure 6 As shown, in one embodiment, the hot pressing assembly includes a support frame 27, a plurality of first electric cylinders 9 are fixedly connected to the top of the support frame 27, and a moving platform 10 is fixedly connected to the telescopic ends of the plurality of first electric cylinders 9 after passing through the support frame 27. An annular hot pressing body 11 is fixedly connected to the bottom of the moving platform 10.

[0035] It should be understood that during the hot pressing process, multiple first electric cylinders 9 are activated, and the multiple first electric cylinders 9 simultaneously push the moving table 10. The moving table 10 drives the annular hot pressing body 11 to press the top of the sleeve ring 2, pressing and heating the horizontal bag body 801 and the vertical annular bag body 802 to achieve hot pressing, so that the horizontal bag body 801 and the vertical annular bag body 802 are hot-pressed into one piece.

[0036] For example, 1. Figure 5 and Figure 6As shown, in one embodiment, the top of the moving platform 10 is provided with a clearance opening 12, and an auxiliary support platform 13 is fixedly installed on the top of the moving platform 10. A second electric cylinder 14 is fixedly connected to the top of the auxiliary support platform 13. The telescopic end of the second electric cylinder 14 passes through the auxiliary support platform 13 and is fixedly connected to a mounting base 15. A first motor 16 is fixedly installed at the bottom of the mounting base 15. A rotating plate 17 is fixedly connected to the output end of the first motor 16. Both ends of the rotating plate 17 are fixedly installed with cutter heads 18. It should be understood that after the horizontal bag body 801 and the vertical annular bag body 802 are hot-pressed into a whole, the second electric cylinder 14 is activated. The second electric cylinder 14 pushes the mounting base 15, and the mounting base 15 drives the first motor 16, the rotating plate 17 and the cutter head 18 to move until the cutter head 18 cuts into the horizontal bag body 801. Then the first motor 16 is activated, and the first motor 16 drives the rotating plate 17 to rotate. The rotating plate 17 drives the cutter head 18 to rotate and cut on the horizontal bag body 801, cutting off the part of the top opening of the vertical annular bag body 802 that is blocked by the horizontal bag body 801.

[0037] As shown in Figure 5, in one embodiment, an elastic telescopic rod 19 is fixedly connected to the bottom of the rotating plate 17 at the middle position, and a pressure head 20 is fixedly connected to the bottom end of the elastic telescopic rod 19. It should be understood that during the process of the cutter head 18 contacting the horizontal bag body 801, the pressure head 20 will first press against the horizontal bag body 801, and then during the process of the cutter head 18 descending to cut the horizontal bag body 801, the pressure head 20 will pre-press and tighten the horizontal bag body 801 to prepare for the cutter head 18 to cut.

[0038] Such as 1 and Figure 7 As shown, in one embodiment, the bottom of the support platform 1 is fixedly connected to two symmetrically arranged support legs 21. Support rails 22 are slidably arranged at the bottom of each support leg 21. A second motor 23 is fixedly connected to the end of each support rail 22. A threaded rod 24 is fixedly connected to the output end of the second motor 23. The threaded rod 24 passes through the support leg 21 and is threadedly connected to the support leg 21. It should be understood that during the installation of the horizontal bag body 801 and the vertical annular bag body 802, the second motor 23 first drives the threaded rod 24 to rotate. The threaded rod 24 then drives the support leg 21 to move, which in turn drives the support platform 1 to move away from the heat-pressing assembly, providing space for the installation of the horizontal bag body 801 and the vertical annular bag body 802. After the horizontal bag body 801 and the vertical annular bag body 802 are installed, the threaded rod drives the support leg 21 and the support platform 1 to move below the heat-pressing assembly for heat pressing.

[0039] like Figure 1 and Figure 7As shown, both ends of the bottom of the two support rails 22 are fixedly connected to the first support base 25. It should be understood that by setting the first support base 25, the two support rails 22 are supported.

[0040] A second support base 26 is fixedly connected to the bottom of the support frame 27, and the second support base 26 is erected above one of the first support bases 25. It should be understood that by setting the second support base 26, the bottom of the support frame 27 is supported.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
