Description

Technical Field

[0001] The utility model relates to the technical field of heat-sealing and hemming, in particular to a heat-sealing and hemming device. Background Art

[0002] In the production of masks, heat-sealing and hemming is a very important technological step. Through heat-sealing and hemming, the edges of the mask can be firmly sealed to ensure that the mask can effectively play a protective role.

[0003] A Chinese patent with the authorization publication number of "CN216255668U" discloses a heat-sealing and hemming device for mask processing. It improves the stability of the heat-sealing plate during movement by using a stabilizing mechanism to prevent the heat-sealing plate from tilting. The adjusting element drives the telescopic rod to descend, and then drives the pressing and fixing block to descend to limit and fix the processed mask, effectively preventing the mask from tilting and maintaining stability.

[0004] However, for the above-mentioned related technology, during the process of heat-sealing and hemming masks, whenever a mask is completed with heat-sealing and hemming, the operator must wait for the heat-sealing plate to reset, then remove the heat-sealed and hemmed mask from the heat-sealing seat, and then place the next mask to be heat-sealed and hemmed. During this process, the equipment is often in an idle state and needs to wait for manual operation to complete before it can continue to work, which undoubtedly greatly reduces the heat-sealing and hemming efficiency of masks. Summary of the Utility Model

[0005] In view of the problems existing in the background art, a heat-sealing and hemming device is proposed. It is provided with a heat-sealing component and a synchronous transposition mechanism, which can make the heat-sealing plates on both sides move in opposite directions, so that the heat-sealing and hemming of masks and the operations of taking, placing, etc. of the heat-sealed and hemmed masks can be carried out synchronously, greatly improving the heat-sealing and hemming efficiency of masks.

[0013] Preferably, the synchronous transposition mechanism includes a rotating shaft, a gear, a rack, a connecting rod, and a self-locking driving member. The rotating shaft is rotatably connected to the back surface of the processing frame. A self-locking driving member is provided at one end thereof, and the other end passes through the processing frame and is connected to a gear located on one side of the partition plate. Racks are meshed on both sides of the gear, and both groups of racks are connected to the T-shaped plate through connections.

A base 2 is provided at the bottom of the processing frame 1, and a partition 3 for separating the operation space is provided inside. Heat-sealing assemblies for performing heat-sealing and edge-locking operations on masks are provided on both the left and right sides inside the processing frame 1. A synchronous transposition mechanism for driving the two heat-sealing assemblies to alternately process masks is provided on one side of the partition 3 inside the processing frame 1.

[0024] As Figure 1 shown, the processing frame 1 is arranged in a rectangular cover structure, and an operation opening for employees to load and unload materials is provided on its front surface.

[0025] As Figure 1 shown, the heat-sealing assembly includes a heat-sealing seat 4 and a heat-sealing plate 5. The heat-sealing seat 4 is located at the bottom inside the processing frame 1, and a placement groove 6 for placing masks is provided thereon. The heat-sealing plate 5 is movably located above it, and a guiding member for defining its moving direction is provided on the heat-sealing plate 5. By placing the mask in the placement groove 6 and using the heat-sealing plate 5 and the heat-sealing seat 4 to close the mold, the heat-sealing and edge-locking operation on the mask is performed.

[0026] As Figure 1 shown, the guiding member includes a T-shaped plate 8. A limiting groove 7 is provided on the partition 3, and the T-shaped plate 8 is slidably connected through the limiting groove 7 in a penetrating manner. The heat-sealing plate 5 is connected to the bottom of the T-shaped plate 8.

[0027] Embodiment 2

[0028] As Figures 1 - 3 shown, a heat-sealing and edge-locking device proposed by the present utility model, on the basis of the above embodiment, this embodiment also details the specific components of the synchronous transposition mechanism and its specific connection manner with the heat-sealing assembly.

[0029] As Figure 3As shown in the figure, the synchronous displacement mechanism includes a rotating shaft 9, a gear 10, a rack 11, a connecting rod 12 and a self-locking driving member. The rotating shaft 9 is rotatably connected to the back surface of the processing frame 1. One end of the rotating shaft 9 is provided with a self-locking driving member, and the other end passes through the processing frame 1 and is connected to a gear 10 located on one side of the partition plate 3. Both sides of the gear 10 are engaged with racks 11. Both groups of racks 11 are connected to the T-shaped plate 8 through connections. By driving the gear 10 to rotate, under the action of the racks 11, the two T-shaped plates 8 can be driven to move synchronously and in opposite directions.

[0030] As Figure 2 shown in the figure, the self-locking driving member includes a fixed frame 13, a motor 14, a worm 15 and a worm gear 16. A fixed frame 13 located outside the rotating shaft 9 is provided on the back surface of the processing frame 1. One end of the fixed frame 13 is connected to a motor 14. The output end of the motor 14 passes through the fixed frame 13 and is connected to a worm 15. A worm gear 16 is engaged on one side of the worm 15. The worm gear 16 is installed on the rotating shaft 9. By driving the worm 15 to rotate by the motor 14, the worm 15 meshes with the worm gear 16 during the rotation process, thereby driving the rotating shaft 9 to rotate.

[0031] In summary, when the present utility model is in use, an employee places a mask in the placement groove 6 on the heat-sealing seat 4, and then starts the motor 14. The motor 14 drives the worm 15 to rotate. During the rotation process of the worm 15, it meshes with the worm gear 16, and the meshing force drives the rotating shaft 9 to rotate. When the rotating shaft 9 rotates, it drives the gear 10 to rotate. When the gear 10 rotates, it cooperates with the racks 11 on both sides thereof to drive the two T-shaped plates 8 to move vertically and in opposite directions under the limitation of the limiting groove 7. During the movement process, one heat-sealing plate 5 is driven to rise, and one heat-sealing plate 5 is driven to descend. The descending heat-sealing plate 5 is closed with the corresponding heat-sealing seat 4, thereby performing a heat-sealing and edge-locking operation on the mask. The rising heat-sealing plate 5 facilitates the blanking and loading operations at this station. As a whole, the heat-sealing and edge-locking of the mask can be synchronized, and operations such as taking and placing the mask with good heat-sealing and edge-locking can be performed, greatly improving the heat-sealing and edge-locking efficiency of the mask.

[0032] The above has described in detail the embodiments of the present utility model in conjunction with the drawings. However, the present utility model is not limited thereto. Within the scope of knowledge possessed by those skilled in the art to which the present utility model pertains, various changes can be made without departing from the gist of the present utility model.
