Description

Technical Field

[0001] This application relates to the field of thread end treatment technology, and more particularly to a thread end treatment device for knitted fabrics. Background Technology

[0002] Knitted fabrics are fabrics woven from yarn or thread using knitting machines or hand knitting tools such as needles and hooks. After processing, the yarn ends need to be treated.

[0003] Existing knitted fabric thread removal equipment cannot synchronously push and control the tension of the knitted fabric on both sides during actual use, resulting in insufficient contact tightness when removing thread ends from the knitted fabric surface and affecting the thoroughness of cleaning. Therefore, this application proposes a knitted fabric thread removal device to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a knitted fabric thread processing device, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a knitted fabric thread end processing device, comprising a frame and a knitted fabric, a horizontal plate fixedly installed on the top of the frame, a frame installed on the top of the horizontal plate, a motor installed on the top of the frame, a lead screw fixedly connected to the power output shaft of the motor, a slider threadedly connected to the outer edge of the lead screw, a vertical rod fixedly connected to the bottom of the slider, a tensioning shaft fixedly connected to the bottom end of the vertical rod, a side plate fixedly installed on the outer side of the slider, one end of a return spring fixedly connected to the bottom of the side plate, a cutter disc fixedly connected to the other end of the return spring, a take-up groove opened on one side of the cutter disc, and a sliding rod fixedly installed on the top of the cutter disc.

[0006] In a preferred embodiment, an electric telescopic rod is fixedly installed at the inner bottom of the frame, and a pressure plate is fixedly connected to the output shaft of the electric telescopic rod.

[0007] By adopting the above technical solution, the driveable electric telescopic rod can move the pressure plate upward, which can then be used to lift the bottom of the knitted fabric, thereby ensuring that the middle of the knitted fabric will not easily collapse downward.

[0008] In a preferred embodiment, the slide bar is slidably connected to the inner wall of the side plate.

[0009] By adopting the above technical solution, when the bottom of the cutter head is subjected to an upward pushing force, the slide rod can slide on the inner wall of the side plate, and the return spring is in a stressed state, which can then be used to adjust the position of the cutter head.

[0010] In a preferred embodiment, a limiting ring is fixedly installed at the inner bottom of the frame, and the bottom end of the lead screw is rotatably connected to the inner wall of the limiting ring.

[0011] By adopting the above technical solution, the stability of the lead screw during rotation can be guaranteed, ensuring that it will not easily shift or sway during rotation, and thus can rotate continuously in a vertical state.

[0012] In a preferred embodiment, two rollers are rotatably mounted on the inner wall of the frame, and two motors for driving the rollers to rotate are mounted on the outer side of the frame.

[0013] By adopting the above technical solution, two motors can be driven to rotate two rollers on the inner wall of the frame, which can then be used for winding and unwinding knitted fabrics respectively.

[0014] In a preferred embodiment, a column is fixedly installed on the inner wall of the frame, the slider is slidably connected to the outer edge of the column, and the upright is slidably connected to the inner wall of the frame.

[0015] By adopting the above technical solution, the slider can be used to guide the slider moving up and down, ensuring that the slider can move up and down stably on the inner wall of the frame when the lead screw rotates, thereby ensuring the stability of the slider movement.

[0016] In a preferred embodiment, the outer edges of the two rollers are respectively wound around the two ends of the knitted fabric, the top of the pressure plate is in contact with the bottom of the knitted fabric, and the tensioning shaft and the cutter disc are both located above the knitted fabric.

[0017] By adopting the above technical solution, the tension of the knitted fabric can be controlled by two rollers, and one of the rollers can be used to wind up the knitted fabric and then move along the cutter disc to scrape off the thread ends on the surface of the knitted fabric. The pressure plate can be used to lift the bottom of the knitted fabric to achieve positioning.

[0018] The beneficial effects of this application are: This knitted fabric thread removal device uses an electric telescopic rod to lift the bottom of the knitted fabric by raising the pressure plate. Then, the motor drives the screw to rotate, which in turn moves the upright and tension shaft downwards through the slider until the tension shaft is in the gap between the roll and the pressure plate, thus squeezing the knitted fabric again to achieve tension control. This ensures the thoroughness of the cutter head in cleaning the thread ends on the surface of the knitted fabric.

[0019] This knitted fabric thread handling equipment can temporarily collect the cleaned thread ends by setting a take-up groove, ensuring that the collected thread ends will not move randomly and making it easy to pick up as a whole. At the same time, a return spring can be used to ensure the adaptability of the cutter disc when dealing with knitted fabrics of different thicknesses. Attached Figure Description

Detailed Implementation

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0023] Reference Figure 1-4 A yarn end processing device for knitted fabrics includes a frame 1 and a knitted fabric 4. A horizontal plate 5 is fixedly installed on the top of the frame 1. A frame 19 is installed on the top of the horizontal plate 5. A motor 6 is installed on the top of the frame 19. A lead screw 7 is fixedly connected to the power output shaft of the motor 6. A slider 8 is threadedly connected to the outer edge of the lead screw 7. A vertical rod 9 is fixedly connected to the bottom of the slider 8. A tensioning shaft 10 is fixedly fixed to the bottom end of the vertical rod 9. A side plate 12 is fixedly installed on the outer side of the slider 8. One end of a return spring 13 is fixedly connected to the bottom of the side plate 12. A cutter disc 14 is fixedly connected to the other end of the return spring 13. A take-up groove 15 is opened on one side of the cutter disc 14. A slide rod 16 is fixedly installed on the top of the cutter disc 14.

[0024] See Figure 2 An electric telescopic rod 17 is fixedly installed at the bottom of the frame 1. The output shaft of the electric telescopic rod 17 is fixedly connected to a pressure plate 18, so that the electric telescopic rod 17 can be driven to move the pressure plate 18 upward, which can be used to lift the bottom of the knitted fabric 4, thereby ensuring that the middle part of the knitted fabric 4 will not easily collapse downward.

[0025] See Figure 4 The slide rod 16 is slidably connected to the inner wall of the side plate 12, so that when the bottom of the cutter head 14 is subjected to an upward pushing force, the slide rod 16 can slide on the inner wall of the side plate 12, and the return spring 13 is in a stressed state, which is then used to adjust the position of the cutter head 14.

[0026] See Figure 4 A limiting ring 20 is fixedly installed on the inner bottom of the frame 19. The bottom end of the lead screw 7 is rotatably connected to the inner wall of the limiting ring 20, which ensures the stability of the lead screw 7 during rotation and prevents it from easily shifting or swaying in position, thus allowing it to rotate continuously in a vertical state.

[0027] See Figure 1 and Figure 2 Two rollers 2 are rotatably mounted on the inner wall of the frame 1, and two motors 3 are mounted on the outer side of the frame 1 to drive the rollers 2 to rotate. This allows the two motors 3 to drive the two rollers 2 to rotate on the inner wall of the frame 1, which can then be used to wind up and unwind the knitted fabric 4 respectively.

[0028] See Figure 4 A column 11 is fixedly installed on the inner wall of the frame 19. The slider 8 is slidably connected to the outer edge of the column 11, and the rod 9 is slidably connected to the inner wall of the frame 19. This allows the slider 8 to be used to guide the slider 8 as it moves up and down, ensuring that the slider 8 can move up and down stably on the inner wall of the frame 19 when the screw 7 rotates, thereby ensuring the stability of the slider 8 when it moves.

[0029] See Figure 1 and Figure 2 The outer edges of the two rollers 2 are respectively wrapped around the two ends of the knitted fabric 4. The top of the pressure plate 18 is in contact with the bottom of the knitted fabric 4. The tensioning shaft 10 and the cutter disc 14 are both set above the knitted fabric 4, so that the tension of the knitted fabric 4 can be controlled by the two rollers 2. The knitted fabric 4 can be wound up by one of the rollers 2 and then moved in contact with the cutter disc 14 to scrape off the thread ends on the surface of the knitted fabric 4. The pressure plate 18 can lift the bottom of the knitted fabric 4 to achieve positioning.

[0030] Working principle: First, the outer edges of the two rollers 2 of the winding device can be wound around both sides of the knitted fabric 4. Simultaneously, the electric telescopic rod 17 can be driven to move the pressure plate 18 upward to lift the bottom of the knitted fabric 4. Then, the motor 6 can be driven to rotate the lead screw 7, which in turn drives the upright rod 9 and the tension shaft 10 downward through the slider 8 until the tension shaft 10 is in the gap between the roller 2 and the pressure plate 18, squeezing the knitted fabric 4 again to achieve tension control. At this time, the cutter disc 14 moves synchronously to the top of the knitted fabric 4. Then, the motor 3 can be driven to rotate one of the rollers 2 to wind up the knitted fabric 4. When the knitted fabric 4 is wound up, it adheres to the bottom of the cutter disc 14, which can scrape off the thread ends adhering to the surface of the knitted fabric 4. The knitted fabric 4 is in a taut state, which can improve the thoroughness of the cleaning.
