Description

Technical Field

[0001] This utility model relates to the field of glove machines, and specifically to a double-line scissor mechanism for glove machines. Background Technology

[0002] The scissor mechanism is an important component of knitting and textile machinery such as glove machines and sock knitting machines. It is used to cut the knitting yarn, allowing the finished gloves, socks, and other products to separate. The most traditional glove machine scissors work on the principle of a set of scissors and a set of pressure plates. When the scissors close to cut the yarn, the other set of pressure plates simultaneously closes and presses the yarn, compressing it before the scissors cut it. The movable piece of the pressure plate is fixed on the same drive shaft that drives the scissors and works simultaneously with them. The pressure plate consists of a fixed piece of about 0.8mm thickness and a movable piece of about 0.48mm thickness. Of course, traditional glove scissors can only cut and press one set of yarn at a time.

[0003] When controlling the knitting of double-yarn gloves, the aforementioned control of both yarns is required simultaneously. Currently, in the market, double-yarn scissors still use a traditional drive shaft to open and close the blades. However, because two sets of yarns need to be pressed together, two pressure plates require additional drive units. These pressure plates need to be individually driven (requiring a certain rigidity to prevent damage or deformation during force application) while maintaining appropriate elasticity (because pressing the yarn utilizes the deformation of a highly elastic metal, typically manganese steel). These functional requirements place two opposite extremes on the pressure plates. The conventional flat structure cannot achieve this function because the existing double-thread scissors design method is as follows: In the traditional sense, the movable pressure plate is still made with a certain thickness and strength to ensure that it does not deform during the process of being driven by force, but it loses the function of using deformation to press the yarn. Therefore, it can only play the function of pulling the yarn. The pressing function requires another elastic metal plate to achieve this. Thus, pressing one set of yarn requires at least one additional fixed pressure plate, and pressing two sets of yarn requires at least two additional fixed pressure plates. Therefore, other double-thread scissors on the market have at least 5 or more pressure plates, and even as many as 8-9, as shown in CN223074367U.

[0004] Because the working space of the glove machine scissors is already very small, there are many small parts in this area, which makes the existing double-line scissor mechanism complex. The large number of parts increases the failure rate and makes maintenance extremely inconvenient.

[0005] Therefore, the inventors conducted further research and developed a double-line scissor mechanism for a glove machine, which led to this invention. Utility Model Content

[0006] The purpose of this invention is to provide a double-line scissor mechanism for a glove machine, which simplifies the structure of the double-line scissor mechanism while maintaining its original function.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A double-wire scissor mechanism for a glove machine, comprising:

[0009] A fixed pressure plate is provided above an upper movable pressure plate and below a lower movable pressure plate. The upper and lower movable pressure plates are oscillating through a driving device, while the fixed pressure plate remains relatively stationary.

[0010] Each end of the upper movable pressure plate and the lower movable pressure plate is provided with an elastic sheet. The thickness of the elastic sheet is less than the thickness of the upper movable pressure plate and the lower movable pressure plate body. The elastic sheet is attached to the fixed pressure plate.

[0011] Due to the aforementioned structure of the upper and lower movable pressure plates, it possesses both rigidity that can be driven independently and appropriate elastic deformation capability to compress the yarn, thus achieving the saving of parts while maintaining the original function.

[0012] Furthermore, the thickness of the upper and lower movable pressure plates is 0.7-1.1 mm; the thickness of the elastic sheet of the upper and lower movable pressure plates is 0.2-0.6 mm.

[0013] Furthermore, the thickness of the upper and lower movable tablet bodies is 0.9 mm.

[0014] Furthermore, the elastic sheet thickness of the upper and lower movable pressure plates is 0.4 mm.

[0015] In the aforementioned values, the range value refers to the thickness that can generally be selected for the upper and lower movable pressure plates, while the fixed value is a preferred embodiment.

[0016] Furthermore, the tail sections of the upper and lower movable pressure plates are each connected to a connecting rod, and the two connecting rods are driven by the same cam.

[0017] Furthermore, the upper movable pressure plate, the fixed pressure plate, and the lower movable pressure plate are all located above the scissor blade.

[0018] Scissor blades are generally divided into fixed scissor blades and movable scissor blades, and the structure of the scissor blades is consistent with existing technology.

[0019] Furthermore, the elastic sheet includes a bending portion and a creasing portion. The bending portion is inclined relative to the main body, and the creasing portion is not on the same plane as the main body.

[0020] The pressing part interacts directly with the yarn during operation, while the bending part mainly serves the function of elastic deformation.

[0021] Furthermore, a groove is provided at the end of the fixed pressure plate, and the groove opening has a V-shaped structure.

[0022] By adopting the above solution, this utility model has the following advantages compared with the prior art:

[0023] The pressure plate has a certain strength and deformation capability, which allows the body under driving force to maintain its thickness. Making the pressure plate into a thin sheet with elastic deformation capability realizes that the movable pressure plate has both rigidity and can be driven independently, while maintaining a suitable elastic deformation capability. Together with the fixed pressure plate, it can press the yarn tightly. Attached Figure Description

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figure 1 As shown, a double-thread scissor mechanism for a glove machine is movable along a horizontal slide bar 7. It includes scissors 2 for cutting threads, a hook 3 for hooking threads, and a pressing plate 1 for pressing threads. The scissors include a fixed scissor blade 21 and a movable scissor blade 22. The pressing plate includes an upper movable pressing plate 11, a fixed pressing plate 12, and a lower movable pressing plate 13. Figure 2As shown, the fixed scissor blade 21 is located at the bottom and is fixed relative to it, while the movable scissor blade 22 is located above the fixed scissor blade 21 and is driven by a shaped rotating shaft to cut the yarn. The fixed pressure plate 12 is located between the upper movable pressure plate 11 and the lower movable pressure plate 13. The fixed pressure plate 12 has two circular through holes, through which the shaped rotating shaft 8 and the fixed shaft 9 pass. However, because the hole diameters do not match the shaped rotating shaft, the fixed pressure plate 12 will not swing with the rotation of the shaped rotating shaft 8. The upper movable pressure plate 11 and the lower movable pressure plate 13 have strip-shaped holes corresponding to the positions of the shaped rotating shaft 8 and circular through holes corresponding to the positions of the fixed shaft. Their tails are connected to their respective connecting rods 4. When the connecting rod 4 swings, the upper movable pressure plate 11 and the lower movable pressure plate 13 swing around the fixed shaft 9. The connecting rod 4 is driven by the same cam 5, which is driven by a motor 6 located below the scissor mechanism.

[0037] The principle of the above structure is the same as that of the original scissor device. The key improvement of this utility model is that, Figure 3 As shown: The upper movable pressure plate 11 and the lower movable pressure plate 13 include a body (111, 131) and an elastic plate. The elastic plate includes a bending part (112, 132) and a pressing part (113, 133). When the body is working, it is parallel to the fixed pressure plate 12. The elastic plate located at the end of the body is bent at an angle so that the pressing part is close to the fixed pressure plate 12. That is, the pressing part 113 of the upper movable pressure plate 11 presses down and the pressing part 133 of the lower movable pressure plate 13 presses up. When the body is driven by the connecting rod 4, it clamps or releases the yarn in the groove of the fixed pressure plate 12 through the pressing part of each part. The end of the fixed pressure plate 12 is provided with a groove, and the opening of the groove is a V-shaped structure.

[0038] In this embodiment, the thickness of the upper movable pressure plate 11 and the lower movable pressure plate 13 is 0.9 mm, and the thickness of the elastic sheet of the upper movable pressure plate 11 and the lower movable pressure plate 13 is 0.4 mm. With the above structure, the driven body of the upper movable pressure plate 11 and the lower movable pressure plate 13 is rigid, and the pressing part has elastic deformation capability, thereby simplifying the double-line scissor mechanism.

[0039] The above are merely specific embodiments of this utility model. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this utility model are for reference only and are not absolute limitations. Any non-substantial modifications made to this utility model shall be considered as infringing upon the protection scope of this utility model.
