Description

Technical Field

[0001] This utility model belongs to the field of textile machinery technology, specifically relating to a rolling feeding device for a webbing cutting machine. Background Technology

[0002] A webbing cutter is a device used to cut webbing. For rubber and elastic webbing, the webbing will be stretched during the feeding process of the cutter, which will cause errors in the cutting process.

[0003] Patent CN111015757A discloses a webbing cutting machine, which describes that a support 8 is provided on the side wall of the housing 1. The upper end of the support 8 extends obliquely upward and is provided with a clamping plate 9. A first rotating shaft 10 passes through the axis of the clamping plate 9 and is fixedly connected to the clamping plate 9. One end of the first rotating shaft 10 is mounted on the upper end of the support 8 through a roller bearing. The webbing can be wound around the first rotating shaft 10 of the clamping plate 9 for storage, which facilitates the transmission device to pull the webbing for rapid feeding.

[0004] However, the bracket 8 in the aforementioned patent is a cantilever structure. The first rotating shaft 10 is mounted on the bracket 8 via roller bearings. Since there is a certain gap between the inner and outer rings of the bearing, the first rotating shaft 10 will wobble during rotation on the bracket 8, which will affect the accuracy of the webbing cutting. In addition, the clamping plate 9 is fixed on the first rotating shaft 10, and the position of the clamping plate 9 on the first rotating shaft 10 is not adjustable. If the width of the webbing to be cut is wide, the webbing cannot be fed. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a rolling feeding device for a webbing cutting machine.

[0006] The specific plan is as follows:

[0007] A webbing cutting machine with a rolling feeding device includes a cutting platform, a cantilever frame, a feeding rod, and at least two clamping discs. Each clamping disc is slidably sleeved on the feeding rod. The feeding rod includes an inner support rod and an outer sleeve. At least two bearings are evenly arranged on the inner support rod. The outer sleeve is sleeved on the inner support rod through the bearings. One end of the inner support rod is fixedly connected to the cantilever frame. The cantilever frame is fixed to one side of the cutting platform.

[0008] Each clamping plate is equipped with a limit ring on both sides, and each limit ring is detachably connected to the feeding rod.

[0009] The side wall of the limiting ring sleeve is provided with a threaded hole and a set screw. The set screw is threadedly connected to the threaded hole, and the limiting ring sleeve is detachably connected to the feeding rod through the set screw.

[0010] Each clamping disc has a through hole at its center, and the inner diameter of the through hole is larger than the outer diameter of the outer sleeve.

[0011] This utility model discloses a rolling feeding device for a webbing cutting machine. The feeding rod includes an inner support rod and an outer sleeve. The inner support rod is fixed on a cantilever frame, and the outer sleeve is rotatably connected to the inner support rod through multiple bearings, which ensures the stability of webbing feeding and improves the cutting accuracy. In addition, the spacing between the clamping discs can be adjusted by adjusting the position of the limiting ring on the feeding rod, so that webbing of different widths can be fed at the same time.

[0014] Figure 3 This is a schematic diagram of the clamping plate and the feeding rod. Detailed Implementation

[0015] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the implementation of this utility model, not all of it. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0016] like Figure 1 and Figure 2 As shown, the webbing cutting machine's rolling feeding device includes a cutting platform 1, a cantilever frame 2, a feeding rod 4, and at least two clamping discs 3. Each clamping disc 3 is slidably sleeved on the feeding rod 4. The feeding rod 4 includes an inner support rod 7 and an outer sleeve 5. At least two bearings 6 are evenly arranged on the inner support rod 7. The outer sleeve 5 is sleeved on the inner support rod 7 through the bearings 6. One end of the inner support rod 7 is fixedly connected to the cantilever frame 2, and the cantilever frame 2 is fixed to one side of the cutting platform 1. The outer sleeve 5 is a steel sleeve. The fixed connection between the inner support rod 7 and the cantilever frame 2 of the feeding rod 4 is preferably welded, ensuring the stability of the feeding rod 4 and the cantilever frame 2. At the same time, multiple bearings are arranged on the inner support rod 7 to ensure the smooth rotation between the outer sleeve 5 and the inner support rod. The outer sleeve 5 rolls through the bearings, and the webbing can slide easily with the help of the machine, reducing the friction of the elastic webbing, eliminating errors generated during webbing recutting, and achieving consistency with the set dimensions.

[0017] In this embodiment, the inner diameter of the bearing is eight millimeters, the outer diameter of the bearing is twelve millimeters, and the inner diameter of the outer sleeve 5 is the same as the outer diameter of the bearing.

[0018] Each clamping plate 3 is provided with a limiting ring 8 on both sides, and each limiting ring 8 is detachably connected to the feeding rod 4.

[0019] The limiting ring 8 has a threaded hole 9 and a set screw 10 on its side wall. The set screw 10 is threadedly connected to the threaded hole 9, and the limiting ring is detachably connected to the feeding rod 4 through the set screw 10. In this embodiment, one end of the set screw 10 rests on the outer sleeve 5 through the threaded hole 9. When the outer sleeve 5 rotates, the limiting ring 8 rotates together with the outer sleeve 5.

[0020] Each clamping disc 3 has a through hole at its center, the inner diameter of which is larger than the outer diameter of the outer sleeve 5. The through hole at the center of the clamping disc 3 is larger than the outer diameter of the outer sleeve 5, allowing the clamping disc 3 to pass through the outer sleeve 5. Furthermore, when the outer sleeve 5 rotates, it does not cause the clamping disc 3 to rotate, reducing the rotational friction of the clamping disc 3. The clamping disc 3 is used to prevent the webbing from deviating during feeding, thus limiting the webbing's movement.

[0021] The working process of the rolling feeding device of the webbing cutting machine is as follows:

[0022] According to the number of webbings, a corresponding number of clamping discs 3 are threaded onto the feeding rod 4. In this embodiment, there are three clamping discs 3, which can feed two webbings at the same time. Then, according to the width of the webbing, the spacing between the different clamping discs 3 is adjusted. After the spacing is adjusted, the cutting platform 1 pulls the webbing off the feeding rod 4. The feeding rod is driven by the webbing and the outer sleeve 5 rolls to feed the webbing. The webbing can slide easily with the help of the machine, reducing the friction of the elastic webbing and eliminating the error generated during the cutting of the webbing, so as to achieve the same size as the set size.

[0023] The spacing between different clamping discs 3 can be adjusted by manually unscrewing the set screws 10 on the limiting rings 3 on both sides of the clamping disc 3, and sliding the limiting rings 8 and the clamping disc 3 on the feeding rod 4. After sliding to the appropriate position, tighten the set screws 10 on the limiting rings 3.

[0024] This utility model discloses a rolling feeding device for a webbing cutting machine. The feeding rod includes an inner support rod and an outer sleeve. The inner support rod is fixed on a cantilever frame, and the outer sleeve is rotatably connected to the inner support rod through multiple bearings, which ensures the stability of webbing feeding and improves the cutting accuracy. In addition, the spacing between the clamping discs can be adjusted by adjusting the position of the limiting ring on the feeding rod, so that webbing of different widths can be fed at the same time.

[0025] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
