Description

Technical Field

[0001] This utility model relates to the field of zipper machine technology, and specifically to a material conveying device for zipper machines. Background Technology

[0002] A zipper machine is a fully automated zipper production line. It is a machine that automatically and continuously assembles the various components of a zipper (cloth bag, zipper teeth, zipper pull, top stop, bottom stop, or end cap, etc.) into a complete zipper. It has achieved high efficiency, standardization, and large-scale zipper production, completely changing the inefficient mode of early hand-sewing of zippers.

[0003] In the zipper manufacturing process, the shaped copper wire needs to be fed into a designated position at the top of the zipper machine, where a cutting blade cuts the copper material to a standard thickness. The cut wire is then fed into a forming mold to form a shaped copper sheet, which is then clamped onto the zipper tape. In existing technology, the material feeding and zipper manufacturing processes of zipper machines are designed separately. That is, the copper wire is fed into the zipper machine through a dedicated material feeding device. This results in the entire machine occupying a large area, having an unsightly appearance, and not being suitable for the process requirements of modern factories. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a material conveying device for zipper machines, which aims to solve the problem that the forming copper wire in the existing zipper machines needs to be fed in through a special material feeding device, resulting in a large footprint of the entire equipment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A material conveying device for a zipper machine includes a connecting plate and a pair of conveying sensing components. The pair of conveying sensing components are symmetrically mounted on the connecting plate. Each conveying sensing component includes a mounting plate, a drive unit, a sensor, and a sliding plate. One end of the mounting plate is fixedly mounted on the connecting plate, and the sensor is fixedly mounted on the other end of the mounting plate. The sliding plate is slidably mounted on the mounting plate, and the sliding plate and the mounting plate form a sliding connection along the length direction of the mounting plate. The drive unit is connected to the sliding plate. A notch is provided on the outer end of the sliding plate, and a roller is rotatably mounted in the notch.

[0007] Furthermore, a slide rail is mounted on the mounting plate, and a groove is provided on the bottom surface of the sensor, with the slide rail slidably mounted in the groove.

[0008] Furthermore, an "L"-shaped limiting plate is fixedly installed on one end of the mounting plate near the roller. One end of the limiting plate is fixedly installed on the upper surface of the mounting plate, and the other end of the limiting plate extends vertically downward. The vertically downward extending end of the limiting plate cooperates with the end of the slide rail near the roller to limit the movement distance of the slide rail.

[0009] Furthermore, the driving unit is a cylinder, and the piston rod of the cylinder is fixedly connected to one end of the slide rail.

[0010] Furthermore, a spring is fitted onto the outer circumferential surface of the piston rod, one end of which is in contact with the end face of the cylinder, and the other end of which is in contact with the inner end face of the piston rod.

[0011] Furthermore, the roller includes a pair of conical limiting portions located at opposite ends and a cylindrical portion located in the middle. The outer diameter of the cylindrical portion is smaller than the outer diameter of the conical limiting portions, and the outer diameter of the conical limiting portions gradually decreases from the outside towards the cylindrical portion.

[0012] Compared with the prior art, the beneficial technical effects of this solution are as follows: The material conveying device for the zipper machine in this solution fixes a pair of conveying sensing components to the bottom of the zipper machine through the connecting part. One end of each of the two rolls of formed copper wire passes through the notch on the conveying sensing component and enters the zipper machine above. During the upward conveying process of the formed copper wire passing through the notch, the formed copper wire contacts the end face of the roller, and the two form rolling friction. As the formed copper wire is conveyed upward, as the upper end of the formed copper wire gradually tightens, the formed copper wire gradually pushes the slide plate to slide towards the drive unit. The sensor senses the sliding distance of the slide plate. When the set sliding value is reached, the drive unit drives the slide plate to move in the opposite direction to reset, realizing the fixed length input of the formed copper wire. Since the above-mentioned material conveying device is set at the bottom of the zipper machine, its structure is simple and its size is small. It makes full use of the bottom space of the zipper machine, thus reducing the floor space and reducing transportation costs. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] See appendix Figures 1 to 2 As shown, this embodiment provides a material conveying device 100 for a zipper machine, including a connecting plate 10 and a pair of conveying sensing components 20. The pair of conveying sensing components 20 are symmetrically installed at opposite ends of the connecting plate 10. The pair of conveying sensing components 20 are used to convey two rolls of formed copper wire into the zipper machine.

[0023] Specifically, the conveying sensing component 20 includes a mounting plate 21, a drive unit 22, a sensor 23, and a sliding plate 25. One end of the mounting plate 21 is fixedly mounted on a connecting plate 10, which is fixedly mounted on the bottom of the zipper machine. The sensor 23 is fixedly mounted on the other end of the mounting plate 21. The sliding plate 25 is slidably mounted on the mounting plate 21, forming a sliding connection between the sliding plate 25 and the mounting plate 21 along the length of the mounting plate 21. The drive unit 22 is connected to the sliding plate 25 and is used to drive the sliding plate 25 to reciprocate along the mounting plate 21. (Refer to...) Figure 3 As shown, a notch 26 is provided on the outer end of the skateboard 25, and a roller 27 is rotatably installed inside the notch 26.

[0024] In use, one end of each of the two rolls of formed copper wire passes through the notch 26 on the conveying sensing component 20 and enters the zipper machine above. As the formed copper wire is conveyed upward through the notch 26, it comes into contact with the end face of the roller 27, and the two form rolling friction. As the formed copper wire is conveyed upward, the upper end of the formed copper wire gradually tightens, and the formed copper wire gradually pushes the slide plate 25 to slide towards the drive unit 22. The sensor 23 senses the sliding distance of the slide plate 25. When the set sliding value is reached, the drive unit 22 drives the slide plate 25 to move in the opposite direction to reset, realizing the fixed length input of the formed copper wire. Since the above-mentioned material conveying device is set at the bottom of the zipper machine, its structure is simple and its size is small. It makes full use of the bottom space of the zipper machine, thus reducing the floor space and reducing transportation costs.

[0025] Reference Figure 1 and Figure 2 As shown, in this embodiment, the sliding connection structure between the mounting plate 21 and the sensor 23 is as follows: a slide rail 24 is mounted on the mounting plate 21, and a groove is provided on the bottom surface of the sensor 23, with the slide rail 24 slidably mounted in the groove.

[0026] Reference Figure 2 As shown, an "L"-shaped limiting plate 28 is fixedly installed on one end of the mounting plate 21 near the roller 27. One end of the limiting plate 28 is fixedly installed on the upper surface of the mounting plate 21, and the other end of the limiting plate 28 extends vertically downward. It can be understood that a gap is reserved between the other end of the limiting plate 28 extending vertically downward and the upper surface of the slide plate 25. In this way, the slide plate 25 will not interfere with the limiting plate 28 and thus prevent the slide plate 25 from reciprocating during the movement of the slide plate 21. The vertically downward extending end of the limiting plate 28 cooperates with the end of the slide rail 24 near the roller 27 to limit the movement distance of the slide rail 24. That is, when the drive unit 22 drives the slide plate 25 to move in the opposite direction and reset, after the slide plate 25 moves to the original position, the slide rail 24 fixed on the slide plate 25 will abut against the vertically downward extending end of the limiting plate 28, which plays a limiting role in the movement and reset of the slide plate 25.

[0027] Reference Figure 2 and Figure 4 As shown, in this embodiment, the drive unit 22 is a cylinder, and the piston rod 29 of the cylinder is fixedly connected to one end of the slide rail 24. Meanwhile, in order to prevent the slide rail 24 from impacting the cylinder during movement, a spring 211 is fitted on the outer circumferential surface of the piston rod 29. One end of the spring 211 is in contact with the end face of the cylinder, and the other end of the spring 211 is installed in contact with the inner end face of the piston rod 29.

[0028] Reference Figure 1 and Figure 3As shown, in this embodiment, the roller 27 includes a pair of conical limiting portions 272 located at opposite ends and a cylindrical portion 271 located in the middle. The outer diameter of the cylindrical portion 271 is smaller than the outer diameter of the conical limiting portions 272. The outer diameter of the conical limiting portions 272 gradually decreases from the outside towards the cylindrical portion 271. With this structural design, when the formed copper wire contacts the end face of the roller 27, the formed copper wire will contact the surface of the cylindrical portion 271 in the middle of the roller 27. Furthermore, the roller 27 has conical limiting portions 272 with an outer diameter larger than that of the cylindrical portion 271 at opposite ends. When the formed copper wire moves, it will not move to the side edges of the roller 27, thus preventing the formed copper wire from entering the side edges of the notch 26 and getting stuck. This ensures that the formed copper wire can move smoothly along the roller 27.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
