[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 2 and Figure 3 As shown, this embodiment provides a technical solution: a pre-depilatory roller device for PVC glove production, comprising a conveyor belt support frame 1, characterized in that a hand mold 11 is provided on the top of the conveyor belt support frame 1, a first depilatory roller 12 and a second depilatory roller 13 are provided on the top of the hand mold 11, and a driving component 2 is provided on the side of the first depilatory roller 12;

[0026] The driving assembly 2 includes a first support frame 21, the side of the first support frame 21 is rotatably connected to the half gear 22 and the gear 23, the side of the first support frame 21 is rotatably connected to the first limit plate 24, the side of the first limit plate 24 is provided with a slide groove 27, the inner cavity of the first support frame 21 is slidably connected to the first slider 25, the side of the half gear 22 and the side of the first slider 25 are fixedly connected to the first fixing rod 26, one end of the first fixing rod 26 is slidably connected to the inner cavity of the slide groove 27, a connecting rod 28 is provided on the side of the gear 23, the middle part of the connecting rod 28 is rotatably connected to the second fixing rod 29, and the end of the second fixing rod 29 away from the connecting rod 28 is connected to the first support frame 2 1 is fixedly connected to the side of the hand mold 1, and the end of the connecting rod 28 away from the gear 23 is fixedly connected to the first elastic piece 210. By setting the first depilatory roller 12, the fingertips of the glove can be demoulded, and by setting the second depilatory roller 13, intermittent depilatory work can be performed on the wrist of the glove to avoid long-term contact with the glove surface and thus causing wear. A driving module is provided on the side of the half gear 22. When in use, the preliminarily dried glove is first placed on the outer surface of the hand mold 11, and then the hand mold 11 is driven to move by the conveyor belt provided on the top of the conveyor belt support frame 1. At this time, the driving module is started, thereby prompting the half gear 22 to rotate clockwise. When the half gear 22 rotates to a certain position, it contacts the side of the gear 23, thereby driving the gear 23 to rotate counterclockwise, and then driving the second depilatory roller 13 to depilate the wrist of the glove. At the same time, when the half gear 22 rotates clockwise, the first fixed rod 26 and the slide groove 27 cooperate to drive one end of the first limiting plate 24 to move downward, and then the first slider 25 can be used to drive the first depilatory roller 12 to move downward. After the first depilatory roller 12 moves downward to a certain position, the bottom of the first depilatory roller 12 contacts the fingertip of the glove, thereby cleaning the gap between the fingertips and avoiding During the production process, burrs appear on the fingertips of the gloves, which affects the subsequent processing work, greatly improving work efficiency. At the same time, when the gear 23 rotates counterclockwise, the teeth of the gear 23 contact the side of one end of the connecting rod 28, thereby prompting the end of the connecting rod 28 that is in contact with the gear 23 to move outward, thereby prompting the other end of the connecting rod 28 to drive the first elastic piece 210 to stretch. When the first elastic piece 210 is stretched to a certain extent, it rebounds, thereby enabling the connecting rod 28 to limit the position of the gear 23, avoiding the position of the gear 23 from shifting during operation, resulting in the problem that the half gear 22 cannot operate normally.

[0027] A step further, such as Figure 3 and Figure 4As shown: a cleaning component 3 is provided on the side of the first support frame 21, and the cleaning component 3 includes a second limiting plate 31, and a third fixing rod 37 is fixedly connected to the side of the second limiting plate 31. A second supporting frame 32 is provided on the top of the second limiting plate 31, and a flexible scraper 33 is fixedly connected to the side of the second supporting frame 32. A third slider 36 is fixedly connected to the side of the second limiting plate 31, and one end of the second supporting frame 32 is fixedly connected to the second slider 35. The second slider 35 and the third slider 36 are opposite to each other and are provided with slopes that match each other. One end of the third fixing rod 37 is slidably connected to the inner cavity of the third fixing rod 37. When the first limiting plate 24 moves downward to a certain position, the half gear 22 continues to rotate clockwise, and through the first fixing rod 26 and the sliding The groove 27 cooperates to prompt the first limit plate 24 to move upward, thereby prompting the first depilatory roller 12 and the second limit plate 31 to move upward. When the first depilatory roller 12 moves to a certain position, the third slider 36 contacts the second slider 35, thereby prompting the second slider 35 to move in the direction of the first depilatory roller 12, thereby driving the second support frame 32 and the flexible scraper 33 to move to the bottom of the first depilatory roller 12. The outer surface of the first depilatory roller 12 contacts the top of the flexible scraper 33, thereby removing the hair debris and impurities attached to the outer surface of the first depilatory roller 12, avoiding the accumulation of impurities on the outer surface of the first depilatory roller 12, affecting the depilation work of the first depilatory roller 12, and greatly improving work efficiency.

[0028] During use, after the flexible scraper 33 completes the cleaning work, when the first depilatory roller 12 moves downward, the second support frame 32 and the flexible scraper 33 are not reset in time, which may cause the movement trajectory of the first depilatory roller 12 to deviate, such as Figure 4 As shown: In the present embodiment, one end of the second slider 35 is fixedly connected to the second spring piece 34. By setting the second spring piece 34, when the second slider 35 is displaced, the second spring piece 34 is compressed to absorb stress. When the first depilatory roller 12 and the second limit plate 31 move downward, the second spring piece 34 releases stress, thereby prompting the second support frame 32 to quickly reset, thereby avoiding the problem of collision with the first depilatory roller 12 due to untimely reset of the second support frame 32, which in turn causes damage.

[0029] Working principle:

[0030] like Figure 1-4 As shown:

[0031] When in use: When in use, first put the preliminarily dried glove on the outer surface of the hand mold 11, and then drive the hand mold 11 to move through the conveyor belt set on the top of the conveyor belt support frame 1. At this time, start the driving module, so that the half gear 22 can be prompted to rotate clockwise. When the half gear 22 rotates to a certain position, it contacts the side of the gear 23, thereby driving the gear 23 to rotate counterclockwise, and then driving the second depilatory roller 13 to depilate the wrist of the glove. At the same time, when the half gear 22 rotates to a certain position, it contacts the side of the gear 23, thereby driving the gear 23 to rotate counterclockwise, thereby driving the second depilatory roller 13 to depilate the wrist of the glove. When rotating clockwise, the first fixed rod 26 cooperates with the slide groove 27 to drive one end of the first limit plate 24 to move downward, and then the first slider 25 can be used to drive the first depilatory roller 12 to move downward. After the first depilatory roller 12 moves downward to a certain position, the bottom of the first depilatory roller 12 contacts the fingertips of the glove, thereby cleaning the gaps between the fingertips. At the same time, when the gear 23 rotates counterclockwise, the teeth of the gear 23 contact the side of one end of the connecting rod 28, thereby prompting the connecting rod 28 to The end of the gear 23 that is in contact with it moves outward, thereby being able to achieve the effect of causing the other end of the connecting rod 28 to drive the first elastic piece 210 to stretch. When the first elastic piece 210 is stretched to a certain extent, it rebounds, thereby being able to achieve the effect of the connecting rod 28 limiting the position of the gear 23. When the first limiting plate 24 moves downward to a certain position, the half gear 22 continues to rotate clockwise, and through the cooperation of the first fixing rod 26 and the sliding groove 27, the first limiting plate 24 can be prompted to move upward, thereby being able to achieve the effect of causing the first depilatory roller 1 2 and the second limit plate 31 move upward. When the first depilatory roller 12 moves to a certain position, the third slider 36 contacts the second slider 35, thereby prompting the second slider 35 to move toward the direction of the first depilatory roller 12, and then driving the second support frame 32 and the flexible scraper 33 to move to the bottom of the first depilatory roller 12. The outer surface of the first depilatory roller 12 contacts the top of the flexible scraper 33, thereby removing the hair scraps and impurities attached to the outer surface of the first depilatory roller 12, and finally completing the depilation work of the gloves.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
