Description

Technical Field

[0001] The utility model relates to the technical field of sewing machine equipment, in particular to a pull cylinder. Background Art

[0002] The cuff wrapping of long-sleeved items and the collar of shirts are both three-in-one processes in clothing production, that is, a process consisting of a three-layer structure (two layers of hemming pieces and a middle main body piece). This process requires folding the rectangular pieces in half and sewing them on the cuffs or collars with a flat machine. However, the difficulty of this method lies in controlling the uniformity of the size of the piece stop and the amount of extension of the main body stop, which may result in poor appearance quality and requires employees with better skills to produce. This process is technically difficult, has low production efficiency, and requires a lot of product rework. It has high technical requirements for operating employees and is very easy to affect the production capacity of the entire production line. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned defects or problems existing in the background technology and to provide a pull tube. By using the pull tube, the operator can quickly and accurately complete the operations such as stop control and center folding of the wrapping strip, thereby improving production efficiency.

[0004] To achieve the above objectives, each embodiment of the present invention adopts the following technical solutions but is not limited to the following solutions:

[0005] The first technical solution relates to a pull cylinder, comprising: a base, which is provided with a horizontal plane; a distribution part, which is located on one side of the base and protrudes from the horizontal plane, and is provided with a side wall perpendicular to the horizontal plane and intersecting the horizontal plane, and the side wall is provided with an entry and exit groove parallel to the horizontal plane and extending along the horizontal plane; and a distribution plate, which is installed in the distribution part and can be telescopically protruded from the entry and exit groove.

[0006] The second technical solution is based on the first technical solution, wherein the distribution part is provided with an inclined surface and a distribution surface, the distribution surface is located above the entry and exit slot, and the inclined surface is located at one side of the distribution part and is connected to the distribution surface as a whole.

[0007] The third technical solution is based on the second technical solution, wherein the portion of the paddle shifter protruding from the entry and exit slot is in a triangular shape, and the farthest end away from the entry and exit slot is one of the corners of the triangle.

[0008] The fourth technical solution is based on the third technical solution, and further includes a spring device. An accommodating space is provided inside the protrusion of the dialing portion to accommodate the spring device, and the spring device is fixedly connected to the dialing sheet.

[0009] The fifth technical solution is based on the fourth technical solution, and further includes an adjustment groove suitable for detachably connecting to a working device, wherein the adjustment groove is located on a side of the distribution portion away from the inclined surface and extends in a direction perpendicular to the side wall.

[0010] From the above description of the various embodiments of the present invention, it can be seen that, compared with the prior art, the various embodiments of the present invention have the following beneficial effects:

[0011] In the first technical solution and related embodiments, the horizontal plane of the base is the position for placing the hemming pieces, and the distribution section is the position for placing the main body pieces. The hemming pieces are divided into upper and lower layers, and the main body pieces are the middle layer. The side walls act as retaining edges, which can effectively block the hemming pieces and prevent them from shifting toward the distribution section during the production process, thereby ensuring product quality and overcoming the drawbacks of traditional practices, which require real-time manual control and have poor results. The design of the entry and exit slots enables the distribution piece to be smoothly extended and retracted in and out, thereby achieving accurate distribution of materials. The distribution piece separates the upper and lower layers of the hemming pieces from the middle layer of the main body pieces, or when the size of the stop is smaller than the distance to the farthest end of the distribution piece, the farthest end of the distribution piece presses against the hemming piece, and the distribution piece retracts in real time to control the position and size of the stop, and ensure that the hemming piece after folding is always centered in half.

[0012] In the second technical solution and related embodiments, due to the design of the inclined surface, the material can enter the distribution surface more smoothly.

[0013] In the third technical solution and related embodiments, the triangle of the divider piece can reduce the contact area between the divider piece and the material, thereby reducing friction and completing the divider operation faster; the farthest end of the triangle away from the entry and exit slot can control the size of the stop. When the size of the stop is smaller than the distance from the farthest end of the divider piece, the farthest end of the divider piece presses against the hemming piece, and the divider piece retracts in real time to control the position and size of the stop.

[0014] In the fourth technical solution and related embodiments, when the stop size of the spring device is smaller than the distance to the farthest end of the dividing plate, the dividing plate presses against the hemming piece, and the spring device ensures that the dividing plate can retract quickly and has better elastic recovery performance, thereby controlling the position and size of the piece, and automatically returns to the initial position after the dividing operation is completed, making the entire operation more stable and reliable.

[0015] In the fifth technical solution and related embodiments, the adjusting groove can adjust the position of the pull tube according to the requirements of the production process, so as to adapt to different stop sizes, thereby improving the application range and flexibility of the pull tube. This design enables the pull tube to better adapt to different production environments and processes, thereby improving production efficiency and product quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figures 1 to 3 ,like Figure 1 and Figure 2 As shown, the pull cylinder 1 includes a base 2, a dividing portion 3, a dividing plate 4, a spring device 5 and an adjusting groove 6.

[0028] The base 2 is provided with a horizontal surface 20 . In this embodiment, the base 2 is used to place the hemming piece 8 .

[0029] Distribution department 3, such as Figure 1 As shown, it includes a side wall 30, an inclined surface 31 and a distribution surface 32. The distribution part 3 is located on one side of the base 2 and protrudes from the horizontal plane 20. It is provided with a side wall 30 perpendicular to the horizontal plane 20 and intersecting with the horizontal plane 20. The side wall 30 is provided with an inlet and outlet slot 300 parallel to the horizontal plane 20 and extending along the horizontal plane 20. The distribution part 3 is provided with an inclined surface 31 and a distribution surface 32. The distribution surface 32 is located above the inlet and outlet slot 300. The inclined surface 31 is located on one side of the distribution part 3 and is connected to the distribution surface 32 as a whole. Specifically, the inclined surface 31 forms an angle with the extension direction of the horizontal plane 20 and is located at the material entry end position. In this embodiment, due to the design of the inclined surface 31, the material can enter the distribution surface 32 more smoothly.

[0030] The dividing plate 4 is installed in the dividing part 3 and can be retracted and protrude from the inlet and outlet slot 300. Since the dividing part 3 protrudes from the base 2, a space is provided inside the dividing plate 4 to accommodate the dividing plate 4. Specifically, the part of the dividing plate 4 protruding from the inlet and outlet slot 300 is in a triangular shape, and the farthest end away from the inlet and outlet slot 300 is one of the corners of the triangle. In this embodiment, the farthest end of the dividing plate 4 away from the inlet and outlet slot 300 is 0.8 cm away from the inlet and outlet slot 300, and 0.8 cm is a common specification of the three-in-one hemming process.

[0031] Spring device 5, such as Figure 2As shown, a space is provided inside the protrusion of the dialing portion 3 to accommodate a spring device 5, and the spring device 5 is fixedly connected to the dialing piece 4. In this embodiment, when the stop size of the spring device 5 is smaller than the distance of the farthest end of the dialing piece 4, the dialing piece 4 presses against the hemming piece 8, and the spring device 5 ensures that the dialing piece 4 can be quickly retracted, and ensures that the dialing piece 4 can have better elastic recovery performance, thereby controlling the position and size of the piece, and automatically returns to the initial position after the dialing operation is completed, making the entire operation more stable and reliable.

[0032] Adjustment slot 6, such as Figure 1 As shown, it is suitable for detachable connection with working equipment, and the adjustment groove 6 is located on the side of the distribution part 3 away from the inclined surface 31 and extends in a direction perpendicular to the side wall 30. The adjustment groove 6 can adjust the position of the pull tube 1 according to the requirements of the production process, so as to adapt to different stop sizes, thereby improving the application range and flexibility of the pull tube 1. This design enables the pull tube 1 to better adapt to different production environments and processes, and improves production efficiency and product quality.

[0033] In this embodiment, Figure 3 As shown, the horizontal surface 20 of the base 2 is where the edge pieces 8 are placed, and the distribution part 3 is where the main body pieces 7 are placed. The edge pieces 8 are divided into two layers, the upper and lower layers, and the main body pieces 7 are the middle layer. Figure 1 As shown, the side wall 30 acts as a retaining edge, which can effectively block the hemming piece 8 and prevent it from deviating toward the distribution part 3 during the production process, thereby ensuring product quality and overcoming the drawbacks of the traditional approach, which requires real-time manual control and has poor results. The design of the entry and exit slot 300 enables the distribution piece 4 to be smoothly extended and retracted in and out, thereby achieving accurate distribution of materials. The distribution piece 4 separates the upper and lower layers of the hemming piece 8 and the middle layer of the main body piece 7, or when the size of the stop is smaller than the distance of the farthest end of the distribution piece 4, the farthest end of the distribution piece 4 presses against the hemming piece 8, and the distribution piece 4 retracts in real time to control the position and size of the stop, and ensure that the hemming piece 8 after folding is always centered.

[0034] In this embodiment, the triangle of the dividing plate 4 can reduce the contact area between the dividing plate 4 and the material, thereby reducing friction and completing the dividing operation faster; the farthest end of the triangle away from the inlet and outlet slot 300 can control the size of the stop.

[0035] The function of the paddle 4 is described below with two embodiments.

[0036] Embodiment 1

[0037] When the stop mouth of the production process is less than or equal to 0.8 cm, the edging piece 8 pushes the dividing piece 4 back, and the spring device 5 pulls back the dividing piece 4. The dividing piece 4 can retract in real time according to the size of the stop mouth. The top end of the dividing piece 4 presses against the strip piece to control the size of the stop mouth and ensure that the edging piece 8 is always folded in the center after being folded.

[0038] Embodiment 2

[0039] When the stop is larger than 0.8 cm in the production process, the edge piece 8 is separated into upper and lower layers, and the main body piece 7 is located in the middle layer. At this time, all the dividing plates 4 are pushed out to increase the area of ​​the dividing plates 4 separating the bottom layer of the edge piece 8 and the middle layer of the main body piece 7.

[0040] The following is an example of the process of wrapping the cuffs with elastic webbing to illustrate the specific work flow.

[0041] like Figure 3 As shown, the spliced ​​elastic webbing is folded in half with the front side facing upward and placed on the horizontal surface 20 of the base 2. Then, the lower layer of elastic webbing is placed below the stopper dividing plate 4. Next, the cuff main body piece 7 is placed with the front side facing upward on the left dividing portion 3 and the stopper dividing plate 4. Finally, the upper layer of elastic webbing is placed on the already placed cuff main body piece 7 to complete the entire placement process.

[0042] Due to the height difference between the left and right sides of the pull tube 1, a side wall 30 is formed, which effectively blocks the lower layer of the cuff elastic webbing, preventing the lower layer of the cuff elastic webbing from shifting to the left during the production process, thereby ensuring product quality. The stopper dividing plate 4 not only separates the elastic webbing from the cuff, but also supports the folded elastic webbing at its top, ensuring that the cuff elastic webbing always remains in a folded state in the center.

[0043] The present application provides a pull tube 1. By using the pull tube 1, an operator can quickly and accurately complete operations such as stop control and center folding of a wrapping strip, thereby improving production efficiency.

[0044] The description of the above specification and embodiments is used to explain the protection scope of the utility model, but does not constitute a limitation on the protection scope of the utility model. Through the enlightenment of the utility model or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent replacements or other improvements to the embodiments of the utility model or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the utility model.
