Description

Technical Field

[0001] Embodiments of this disclosure relate to the field of cutter technology, and more specifically, to a cutter for cotton yarn. Background Technology

[0002] Cotton yarn is a type of yarn made from cotton through spinning processes. It is an important raw material in the textile industry and is widely used in weaving various fabrics, knitwear, home textiles, embroidery, and industrial fabrics. Before processing cotton yarn, it needs to be cut and trimmed to suit different items.

[0003] When there are few finished products to be prepared or a small number of cotton yarns to be cut, there is no need to use large cutting equipment to cut them. Usually, cutting shears or automatic cutters are used to manually cut the cotton yarns, so that the required size can be cut flexibly.

[0004] However, regardless of whether scissors or a cutting tool are used for cutting, the cotton yarn needs to be stretched and tightened before cutting to ensure a smooth cut. Therefore, two people are required to do the cutting work. One worker pulls the cotton yarn to the cutting length to tighten it, while the other worker holds the cutting tool to cut. This method requires more manpower and two people to cooperate, which is quite inconvenient. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this disclosure provide a cotton yarn cutter to solve the technical problem in the prior art that two workers are required to cooperate in cutting cotton yarn, which is inconvenient.

[0006] According to one aspect, at least one embodiment of this disclosure provides a cotton yarn cutter, including a pressure box, a mounting plate, a moving assembly, a pressure frame, and a cutting assembly. The pressure box has an internal cavity. The mounting plate is fixedly mounted on the top of the pressure box. The moving assembly is disposed within the cavity of the pressure box. The pressure frame is disposed on the moving assembly. The moving assembly is used to drive the pressure frame to move, thereby pressing and fixing cotton yarns of different lengths. The cutting assembly is disposed on the pressure box via a reciprocating assembly and is used to cut the cotton yarn.

[0007] Furthermore, the moving component includes a reciprocating screw, a throttle, and a translation frame. The reciprocating screw is rotatably installed in the cavity of the lower pressure box, and a matching screw nut is installed on the reciprocating screw. The throttle is coaxially connected to the reciprocating screw. One end of the translation frame is fixedly connected to the top end of the screw nut, and the other end of the translation frame is fixedly connected to the top end of the lower pressure frame.

[0008] Furthermore, the reciprocating assembly includes an electric cylinder, a sliding box, a sliding rod, a sliding block, a pulling assembly, and a stabilizing assembly. The electric cylinder is mounted on the top of the mounting plate, the sliding box is fixedly mounted on the output end of the electric cylinder, the sliding rod is fixedly mounted inside the sliding box, the sliding block is slidably mounted on the sliding rod, the pulling assembly is disposed on the sliding block, and the stabilizing assembly is disposed on the electric cylinder.

[0009] Furthermore, the pulling assembly includes a pulling rod, a limiting block, and a bolt. One end of the pulling rod is fixedly installed on the side of the sliding block, the limiting block is fixedly installed on the top of the sliding box, and the bolt is threadedly connected to the limiting block and the side of the pulling rod.

[0010] Furthermore, the cutting assembly includes a motor and a cutting blade. The motor is mounted on the bottom end of the sliding block via a mounting cover, and the cutting blade is mounted on the output end of the motor.

[0011] Furthermore, the stabilizing component includes a fixing ring and a stabilizing frame. The fixing ring is fixedly installed on the output end of the electric cylinder, and stabilizing frames are fixedly installed on both sides of the fixing ring. The bottom end of the stabilizing frame is fixedly connected to the top end of the sliding box.

[0012] In order to press cotton yarn of different widths, the pressing frame is further configured as U-shaped, and the pressing box is set in the groove of the pressing frame.

[0013] In order to enable the pressure frame to slide smoothly on the side of the pressure box, furthermore, the pressure box has sliding grooves on both sides, and the two inner sidewalls of the pressure frame are fixedly installed with sliders, which are slidably installed in the sliding grooves of the pressure box.

[0014] The beneficial effects of the embodiments disclosed herein are as follows:

[0015] 1. In this disclosure, when cutting cotton yarn, the position of the lower pressure frame can be adjusted by the moving component according to the width of different cotton yarns. Then, one end of the cotton yarn is fixed and pressed by the lower pressure frame and the lower pressure box. Then, the other end of the cotton yarn is pulled by the other hand of the cutting operator to make the cotton yarn taut.

[0016] 2. In this disclosure, after tensioning is completed, the reciprocating component can drive the cutting component to cut and separate the cotton yarn, and the height of the cutting component can be adjusted so that the cutting blade contacts the cotton yarn and cuts it;

[0017] In summary, this cutter, through the cooperation between the pressure box, mounting plate, moving component, pressure frame and cutting component, allows only one worker to tighten and cut cotton yarn, saving manpower and making it more convenient compared to the need for multiple workers to work together to cut.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-6As shown, a cotton yarn cutter according to an embodiment of the present disclosure includes a pressure box 1, a mounting plate 2, a moving assembly, a pressure frame 3, and a cutting assembly. The pressure box 1 has an internal cavity. The mounting plate 2 is fixedly installed on the top of the pressure box 1. The moving assembly is disposed in the cavity of the pressure box 1. The pressure frame 3 is disposed on the moving assembly. The moving assembly is used to drive the pressure frame 3 to move, thereby pressing and fixing cotton yarns of different lengths. The cutting assembly is disposed on the pressure box 1 via a reciprocating assembly and is used to cut the cotton yarn.

[0033] like Figure 2 and Figure 6 As shown, when cutting cotton yarn, the cotton yarn is first placed on a table, and the required length is measured. Then, the cut portion is suspended in the air, and the pressure box 1 is placed above the cotton yarn to press it down. The pressure frame 3 can be moved and adjusted according to the width of different cotton yarns via a moving component. The moving component includes a reciprocating screw 4, a throttle 6, and a translation frame 7. The reciprocating screw 4 is rotatably installed in the cavity of the pressure box 1, and a matching screw nut 5 is installed on the reciprocating screw 4. The throttle 6 is coaxially connected to the reciprocating screw 4. One end of the translation frame 7 is fixedly connected to the top of the screw nut 5, and the other end of the translation frame 7 is fixedly connected to the top of the pressure frame 3. Specifically, by rotating the throttle 6, the rotating plate drives the reciprocating screw. 4. The screw nut 5 rotates within the cavity of the lower pressure box 1, while the reciprocating screw 4 drives the translation frame 7 to move. Since both sides of the lower pressure box 1 have sliding grooves, and the two inner sidewalls of the lower pressure frame 3 are fixedly installed with sliders 19, which slide in the sliding grooves of the lower pressure box 1, the lower pressure frame 3 moves on both sides of the lower pressure box 1, thereby lengthening the pressed length. Since the lower pressure frame 3 is U-shaped and the lower pressure box 1 is located in the groove of the lower pressure frame 3, when pressing shorter cotton yarn, it can pass through the cavity of the lower pressure frame 3 and into the lower pressure box 1, making it shorter. It should be noted that both the lower pressure frame 3 and the lower pressure box 1 are made of iron, so after pressing, the cotton yarn can be fixed without manual pressing.

[0034] like Figure 3 , Figure 4 and Figure 5As shown, after the cotton yarn is pressed, the other end of the cotton yarn is manually stretched by the worker and then cut by the cooperation of the reciprocating component and the cutting component. The reciprocating component includes an electric cylinder 8, a sliding box 9, a sliding rod 10, a sliding block 11, a pulling component, and a stabilizing component. The electric cylinder 8 is installed on the top of the mounting plate 2, the sliding box 9 is fixedly installed on the output end of the electric cylinder 8, the sliding rod 10 is fixedly installed inside the sliding box 9, the sliding block 11 is slidably installed on the sliding rod 10, the pulling component is set on the sliding block 11, and the stabilizing component is set on the electric cylinder 8. The pulling component includes a pulling rod 12, a limit block 13, and... Bolt 14 is fixedly installed on the side of the sliding block 11 at one end of the pull rod 12. Limiting block 13 is fixedly installed on the top of the sliding box 9. Bolt 14 is threadedly connected to the side of the limiting block 13 and the pull rod 12. The stabilizing assembly includes a fixing ring 17 and a stabilizing frame 18. The fixing ring 17 is fixedly installed on the output end of the electric cylinder 8. Stabilizing frames 18 are fixedly installed on both sides of the fixing ring 17, and the bottom end of the stabilizing frame 18 is fixedly connected to the top of the sliding box 9. The cutting assembly includes a motor 15 and a cutting blade 16. The motor 15 is installed on the bottom end of the sliding block 11 through a mounting cover, and the cutting blade 16 is installed on the output end of the motor 15.

[0035] Specifically, the motor 15 is started, and its output drives the cutting blade 16 to rotate. Simultaneously, the electric cylinder 8 is activated, and its output drives the sliding box 9 to move downwards, thus synchronously driving the cutting blade 16 downwards to contact the cotton yarn and cut it. Then, the operator uses their other hand to move the pull rod 12 horizontally, which in turn drives the sliding block 11 to move horizontally. The sliding block 11 then drives the mounting cover and the cutting blade 16 to move horizontally, thus cutting the cotton yarn to its width. While the electric cylinder 8 drives the sliding box 9 downwards, the connection between the stabilizing ring and the stabilizing frame 18 ensures that the sliding box 9 moves smoothly downwards. When cutting is not required, the sliding block 11 is moved to the far side of the sliding rod 10. It should be noted that the side of the limiting block 13 has a groove. The side of the pull rod 12 is then inserted into the groove of the limiting block 13, and the bolt 14 is threaded in to secure it.

[0036] Working principle: When cutting cotton yarn, first place the cotton yarn on the table and measure the required length. Then, suspend the part to be cut in the air and place the pressure box 1 above the cotton yarn to press it. Then, depending on the width of the cotton yarn, turn the handle 6. The rotating plate drives the reciprocating screw 4 to rotate in the cavity of the pressure box 1. The screw nut 5 drives the translation frame 7 to move on the reciprocating screw 4. The pressure frame 3 moves on both sides of the pressure box 1, thereby increasing the length of the pressed cotton yarn. After pressing, the operator pulls the other end of the cotton yarn to tighten it. Then, start the motor 15. The output end of the motor 15 drives the cutting blade 16 to rotate. At the same time, start the electric cylinder 8. The output end of the electric cylinder 8 drives the sliding box 9 to move down, thereby synchronously driving the cutting blade 16 to move down and contact the cotton yarn to cut it. Finally, move the translating pull rod 12. The pull rod 12 drives the sliding block 11 to move synchronously. The sliding block 11 drives the mounting cover and the cutting blade 16 to move, thereby cutting the cotton yarn to the required width.
