Description
Technical Field
[0001] The utility model relates to the technical field of textile machinery, in particular to a shearing device of a circular towel knitting machine. Background Art
[0002] A circular terry knitting machine is a mechanical device used to produce towels. Through the interaction of multiple needles and yarn, it weaves towels with a certain thickness and softness. However, after knitting, the terry cloth often has some excess fluff on its surface. This not only affects the product's appearance but can also reduce its comfort. Therefore, a shearing device is required to trim the towel surface to remove the excess fuzz and achieve a smooth and even surface.
[0003] Existing shearing devices mostly use fixed blades for trimming, which makes it difficult to accurately control the length and uniformity of the shearing, and easily leads to floating hair of varying lengths on the surface of the towel; at the same time, existing shearing devices are mostly designed for specific types of towels and are difficult to adapt to towel products of different thicknesses and materials.
[0004] Based on this, it is necessary to design a shearing device of a circular towel knitting machine that can evenly and accurately trim the floating hair of the towel. Utility Model Content
[0005] A shearing device for a circular towel knitting machine comprises a frame, a tool for trimming the floating hair of the towel being rotatably connected between two protrusions in the length direction of the frame, a motor three for driving the tool to rotate being installed on the frame, an output shaft of the motor three being connected to one end of the tool, two guide rods two and two bidirectional screw rods one being arranged in parallel on the frame, the guide rod two and the bidirectional screw rod one being arranged on both sides of the tool, a sliding frame two being movably connected between the guide rod two and the bidirectional screw rod one on the same side, a limiting rod being rotatably connected between the two sliding frames two, the limiting rod being located directly below the tool, the towel passing between the limiting rod and the tool, and the distance between the limiting rod and the tool being adjusted to achieve adjustment of the trimming length of the floating hair of the towel by the tool.
[0006] Further explanation: support plates are symmetrically installed on the two outer walls in the length direction of the frame, and motor 2 is installed on each support plate. The output shaft of motor 2 is connected to the upper end of bidirectional screw rod 1 through a coupling. Motor 2 is used to drive bidirectional screw rod 1 to rotate to adjust the distance between the limit rod and the tool.
[0007] To further explain, a bearing seat is installed on an inner wall in the length direction of the frame, and a motor 1 is installed on the other inner wall. A feed shaft is connected to the output shaft of the motor 1, and the feed shaft is rotatably connected to the bearing seat. A guide rod 1 parallel to the bidirectional screw rod 1 is provided on the frame, and a sliding frame 1 is movably connected between the guide rod 1 and the bidirectional screw rod 1. A rotating shaft is rotatably connected between the two sliding frames 1, and the rotating shaft is provided directly above the feed shaft, and the towel passes between the rotating shaft and the feed shaft.
[0008] To further illustrate, when the bidirectional screw rod 1 rotates, the movement directions of the sliding frame 1 and the sliding frame 2 are opposite.
[0009] Further explanation: both the rotating shaft and the feeding shaft are sleeved with rubber sleeves.
[0010] Further explanation: a guide rod three and a bidirectional screw rod two are arranged parallel between the two protrusions in the length direction of the frame, and two limit plates for adapting to the width of the towel are movably connected between the guide rod three and the bidirectional screw rod two. The distance between the two limit plates can be adjusted by driving the bidirectional screw rod two to rotate to adapt to towels of different widths.

[0013] The beneficial effects of the utility model are as follows: 1. The rotation of the bidirectional screw rod drives the sliding frame 2 to move up and down along the guide rod 2, thereby adjusting the distance between the limit rod and the tool. The motor 3 drives the tool to rotate at high speed to realize the function of the tool to accurately trim the floating hair on the towel, thereby ensuring the uniformity and accuracy of the shearing, improving the shearing quality and the aesthetics of the towel; at the same time, by adjusting the distance between the limit rod and the tool, the tool can realize the function of shearing towels of different thicknesses.
[0014] 2. When motor 2 drives bidirectional screw 1 to rotate, sliding frame 1 is raised and lowered along guide rod 1, thereby adjusting the distance between the feeding shaft and the rotating shaft to achieve effective transportation of towels of different thicknesses.

DETAILED DESCRIPTION
[0021] The following describes embodiments of the present invention with reference to the accompanying drawings.
[0022] Embodiment: A shearing device for a circular towel knitting machine, such as Figure 1 and Figure 2 As shown, it includes a frame 1, a motor 3 15, a sliding frame 2 12, a guide rod 2 13, a bidirectional screw rod 1 9, a limit rod 14 and a tool 16. The tool 16 for trimming the floating hair of the towel is rotatably connected between the two protrusions in the length direction of the frame 1. The motor 3 15 for driving the tool 16 to rotate is installed on the frame 1. The output shaft of the motor 3 15 is connected to one end of the tool 16 through a coupling. The motor 3 15 is used to drive the tool 16 to rotate at a high speed to trim the floating hair of the towel. Two guide rods 2 13 and two bidirectional screw rods 1 9 are arranged in parallel on the frame 1. The guide rod 2 13 and the bidirectional screw rod 1 9 are arranged on the tool 16. On the left and right sides, a sliding frame 2 is movably connected between the guide rod 2 13 and the bidirectional screw rod 1 9 on the same side. Here, the sliding frame 12 is slidably connected to the guide rod 2 13, and the sliding frame 12 is threadedly connected to the upper part of the bidirectional screw rod 9. The front and rear sliding frames 2 are rotatably connected with a limit rod 14. The limit rod 14 is located directly below the tool 16. The towel passes between the limit rod 14 and the tool 16. By adjusting the distance between the limit rod 14 and the tool 16, the tool 16 can accurately adjust the trimming length of the towel's floating hair. At the same time, it can adapt to towels of different thicknesses and achieve accurate and uniform trimming of the floating hair of towels of different thicknesses.
[0023] like Figure 2 As shown, support plates 10 are symmetrically installed on the two outer walls of the frame 1 in the length direction, and motor 2 11 is installed on each of the support plates 10. The output shaft of motor 2 11 is connected to the upper end of the bidirectional screw rod 1 9 through a coupling. Motor 2 11 is used to drive the bidirectional screw rod 1 9 to rotate to adjust the distance between the limit rod 14 and the tool 16. The bidirectional screw rod 1 9 is driven to rotate by motor 2 11, thereby driving the sliding frame 12 to move up and down on the upper part of the bidirectional screw rod 1 9, so as to adjust the distance between the limit rod 14 and the tool 16, and realize precise adjustment of the distance between the limit rod 14 and the tool 16 according to the thickness of the towel, thereby providing convenience for the tool 16 to accurately trim the floating hair of the towel.
[0024] like Figure 2 and Figure 3 As shown, a bearing seat 2 is installed on an inner wall in the length direction of the frame 1, and a motor 6 is installed on the other inner wall. A feed shaft 3 is connected to the output shaft of the motor 6, and the end of the feed shaft 3 away from the motor 6 is rotatably connected to the bearing seat 2. A guide rod 8 is provided on the frame 1, which is parallel to the bidirectional screw rod 9. A sliding frame 7 is movably connected between the guide rod 8 and the bidirectional screw rod 9. Here, the sliding frame 7 is threadedly connected to the lower part of the bidirectional screw rod 9. When the bidirectional screw rod 9 rotates, the movement directions of the sliding frame 7 and the sliding frame 2 12 are opposite, thereby realizing that the sliding frame 7 and the sliding frame 2 12 are close to or away from each other, thereby realizing the thickness of the towel. The spacing between the limit rod 14 and the tool 16 and the spacing between the feed shaft 3 and the rotating shaft 4 are synchronously adjusted. The slide 7 is slidably connected to the guide rod 8. The rotating shaft 4 is rotatably connected between the two slides 7. The rotating shaft 4 is arranged directly above the feed shaft 3. The towel passes between the rotating shaft 4 and the feed shaft 3. When the motor 6 drives the feed shaft 3 to rotate, the feed shaft 3 drives the towel to move forward and drives the rotating shaft 4 to rotate. The rotation direction of the rotating shaft 4 is opposite to that of the feed shaft 3. Rubber sleeves 5 are both sleeved on the rotating shaft 4 and the feed shaft 3. The arrangement of the rubber sleeve 5 facilitates increasing the contact area between the feed shaft 3 and the rotating shaft 4 and the towel, thereby facilitating driving the towel to move forward.
[0025] When in use, motor 2 11 drives the bidirectional screw 1 9 to rotate, thereby driving the sliding frame 1 7 and the sliding frame 2 12 to perform lifting movements, thereby adjusting the distance between the feed shaft 3 and the rotating shaft 4, the limit rod 14 and the tool 16, so as to adapt to the thickness of the towel; then, the tool 16 is driven by motor 3 15 to rotate at high speed, thereby cutting off the excess fluff on the surface of the towel, thereby completing the shearing operation on the surface of the towel; when motor 1 6 is working, it drives the feed shaft 3 to rotate clockwise, and drives the towel forward through the rubber sleeve 5 provided on the feed shaft 3, and thereby drives the rotating shaft 4 to rotate counterclockwise, thereby realizing the forward conveyance of the towel that has completed the shearing operation, realizing the effective conveyance of towels of different thicknesses, and ensuring the continuity and stability of the shearing process.
[0026] like Figure 4As shown, a guide rod three 17 and a bidirectional screw rod two 18 are arranged in parallel between the two protrusions in the length direction of the frame 1, and two limit plates 20 for adapting to the width of the towel are movably connected between the guide rod three 17 and the bidirectional screw rod two 18. Here, the bidirectional screw rod 18 is threadedly connected to the limit plate 20, and the guide rod three 17 is slidingly connected to the limit plate 20. A motor four 19 is provided on the frame 1 for driving the bidirectional screw rod two 18 to rotate. The output shaft of the motor four 19 is connected to one end of the bidirectional screw rod two 18, and the bidirectional screw rod two 18 is driven to rotate by the motor four 19, thereby driving the two limit plates 20 to approach or move away from each other along the guide rod two 18, thereby achieving adaptation to towels of different widths, ensuring that the towels will not deviate during the shearing process, and improving the accuracy and efficiency of shearing.
[0027] The motor 4 19 drives the bidirectional screw rod 2 18 to rotate, thereby driving the limit plate 20 threadedly connected to the bidirectional screw rod 2 18 to move horizontally along the guide rod 3 17, so as to adjust the distance between the two limit plates 20, thereby limiting the towels of different widths and ensuring that the towels will not deviate during the shearing process.
[0028] like Figure 1 As shown, a vacuum cleaner 21 is installed on the top of the two support plates 10. The dust nozzle 22 of the vacuum cleaner 21 is arranged above the frame 1, and the opening of the dust nozzle 22 faces the cutter 16. When the vacuum cleaner 21 is working, the floating hair trimmed by the cutter 16 is sucked into the vacuum cleaner 21 through the dust nozzle 22, thereby ensuring the cleanliness of the table top of the frame 1.
[0029] The cutter 16 collects the loose hair trimmed from the towel through the suction nozzle 22 of the vacuum cleaner 21, thereby keeping the table of the rack 1 clean and preventing the loose hair from flying around, thereby ensuring a clean working environment.
[0030] It should be understood that the above description is only for illustrative purposes and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be within the scope of the claims herein.
