Abstract
Description
Technical Field
[0001] This utility model relates to the field of mask processing technology, and in particular to an automatic folding device for mask ear loops. Background Technology
[0002] When processing masks, after connecting the ear loops to the face shield, the ear loops need to be folded up and placed on the mask. The unfolded ear loops are folded and pressed by rotating the folding plate. Since masks come in different sizes, such as large, medium and small, the existing folding device cannot be adjusted, which means that the ear loops can only be folded for masks of a fixed size, thus affecting the adaptability of the device. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing folding devices in the prior art, which cannot be adjusted and can only fold the ear loops of masks of fixed specifications, thus affecting the adaptability of the device. Therefore, this invention proposes an automatic ear loop folding device for masks.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] Design an automatic folding device for mask ear loops, including a base, a horizontal plate fixedly connected to the base, two movable plates abutting at both ends of the horizontal plate, a folding plate connected to each of the two movable plates via a rotating mechanism, a bidirectional threaded rod rotatably connected to the base via a bearing, a connecting ear fixedly connected to both ends of the bidirectional threaded rod, the two connecting ears being fixedly connected to the movable plates respectively, and a conveyor belt provided on both sides of the two horizontal plates.
[0006] Preferably, the rotating mechanism includes a rotating shaft, which is rotatably connected to the movable plate via a bearing. A folding plate is fixedly connected to the rotating shaft, and a gear is fixedly connected to the rotating shaft. A rack meshes with the gear, and the rack moves via the moving mechanism.
[0007] Preferably, the moving mechanism includes a connecting rib, which is fixedly connected to the rack, and a connecting sleeve is fitted on the connecting rib. A second telescopic rod is fixedly connected to the connecting sleeve, and the second telescopic rod is fixedly connected to the base.
[0008] Preferably, two fixing plates are fixedly connected to the base, and a first telescopic rod is fixedly connected to each of the two fixing plates. A guide plate is fixedly connected to the inner side of each of the two first telescopic rods.
[0009] Preferably, a protective plate is fixedly connected to both of the movable plates.
[0010] Preferably, both ends of the bidirectional threaded rod are fixedly connected to rotating blocks.
[0011] Preferably, both the first telescopic rod and the second telescopic rod are electrically operated telescopic rods.
[0012] The present invention proposes an automatic ear loop folding device for face masks, which has the following advantages: by rotating the threaded rod, two moving plates are driven to move towards each other or away from each other. When pressing and folding, the edges of the two moving plates are aligned with the face mask. When the folding plate rotates, the ear loops are folded and pressed onto the face mask, thereby pressing and folding the ear loops of face masks of different sizes, which improves the adaptability of the device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Example 1: Refer to Figure 1-5An automatic ear loop folding device for face masks includes a base 1, a horizontal plate 12 fixedly connected to the base 1, and movable plates 11 abutting at both ends of the horizontal plate 12. Folding plates 6 are connected to both movable plates 11 via a rotating mechanism. A bidirectional threaded rod 10 is rotatably connected to the base 1 via bearings. Rotating blocks are fixedly connected to both ends of the bidirectional threaded rod 10, and connecting ears are fixedly connected to both ends of the bidirectional threaded rod 10. The two connecting ears are respectively fixedly connected to the movable plates 11. Conveyor belts are provided on both sides of the two horizontal plates 12. By rotating the threaded rod 10, the two movable plates 11 are driven to move towards each other or away from each other. During pressing and folding, the edges of the two movable plates 11 are aligned with the face mask. When the folding plates 6 rotate, the ear loops are folded and pressed onto the face mask, thereby pressing and folding the ear loops of face masks of different sizes, improving the adaptability of the device.
[0021] The rotating mechanism includes a rotating shaft 15, which is rotatably connected to a movable plate 11 via a bearing. A folding plate 6 is fixedly connected to the rotating shaft 15, and a gear 14 is fixedly connected to the rotating shaft 15. A rack 13 meshes with the gear 14. The rack 13 moves through the moving mechanism, which drives the gear 14 to rotate, thereby driving the folding plate 6 to rotate and folding and pressing the ear loops.
[0022] The moving mechanism includes a connecting rib 8, which is fixedly connected to the rack 13. A connecting sleeve 9 is fitted onto the connecting rib 8, and a second telescopic rod 7 is fixedly connected to the connecting sleeve 9. Both the first telescopic rod 4 and the second telescopic rod 7 are electric telescopic rods. The second telescopic rod 7 is fixedly connected to the base 1. The second telescopic rod 7 extends and retracts, driving the connecting sleeve 9 to move, thereby driving the connecting rib 8 to move. When the two moving plates 11 move, the position of the connecting rib 8 in the connecting sleeve 9 will be adjusted.
[0023] Example 2: Refer to Figure 2-5 As another preferred embodiment of this utility model, based on embodiment 1, protective plates 5 are fixedly connected to both movable plates 11 to prevent the masks from slipping and prevent the masks from contacting the gears 14 and racks 13, which could cause damage to the masks.
[0024] Example 3: Reference Figure 2-4 As another preferred embodiment of this utility model, based on embodiment 1, two fixed plates 2 are fixedly connected to the base 1, and a first telescopic rod 4 is fixedly connected to each of the two fixed plates 2. A guide plate 3 is fixedly connected to the inner side of each of the two first telescopic rods 4. By using the first telescopic rods 4 to extend and retract, the distance between the two guide plates 3 is adjusted. The guide plates 3 play a role in tidying up the mask that passes through, so that the edge of the mask is aligned with the edge of the moving plate 11 and the mask, ensuring the accuracy of the ear loop folding.
[0025] In use, the mask is placed on the conveyor belt. Guided by two guide plates 3, the mask's edge aligns with the edge of the moving plate 11 and enters the moving plate 11. The second telescopic rod 7 extends and retracts, causing the connecting sleeve 9 to move, which in turn moves the connecting rib 8, causing the rack 13 to move, which in turn rotates the gear 14, causing the folding plate 6 to rotate. The folding plate 6 folds and presses the ear loops. When the next mask moves onto the moving plate 11, the pressed mask is extruded and passes through another conveyor belt to enter the next processing step.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
