Description

Technical Field

[0001] This utility model relates to the field of wool processing technology, specifically to a wool cutting device that can prevent wool from getting tangled in the wool roller. Background Technology

[0002] Wool tops are continuous strip-shaped semi-finished products made through processes such as combing and combining in wool spinning. They are composed of parallel and straight fibers, have uniform thickness and good spinnability, and are an important raw material for subsequent spinning and weaving. Wool top cutting is the precise cutting of continuous wool tops into segments of specific lengths according to production needs. It is a key step connecting wool top preparation and subsequent processing.

[0003] Currently, during the sliver cutting process, due to the inherent electrostatic adsorption of fibers and the static electricity generated by friction between the fibers and the sliver roller surface during cutting, as well as the possibility of residual grease or moisture during processing, loose slivers easily adhere to the conveying sliver roller. This not only affects cutting efficiency but may also cause the sliver roller to jam due to accumulation, requiring regular cleaning to ensure smooth production. Therefore, we propose a sliver cutting device that can prevent slivers from getting tangled in the sliver roller. Utility Model Content

[0004] The purpose of this invention is to provide a sliver cutting device that prevents sliver from tangling into the sliver roller. It guides the sliver before and after conveying, and limits its position during conveying, effectively preventing loose sliver from adhering to the sliver roller, thus improving cutting efficiency. This invention solves the current problem in sliver cutting where fibers have a certain electrostatic adsorption property, and static electricity is generated by friction between the fibers and the sliver roller surface during cutting. Additionally, small amounts of grease or moisture may remain on the sliver during processing, causing loose sliver to easily adhere to the conveying sliver roller. This not only affects cutting efficiency but can also cause the sliver roller to jam due to accumulation, requiring regular cleaning to ensure smooth production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sliver cutting device that prevents sliver from tangling into a sliver roller, comprising a fixed frame, an active roller rotatably mounted inside the fixed frame, the active roller having a plurality of annular grooves evenly spaced on its outer surface, a driven roller positioned above the active roller inside the fixed frame, a pressure ring fixedly fitted onto the outer surface of the driven roller at each annular groove, a guide plate A and a guide plate B fixedly mounted inside the fixed frame at positions in front of and behind the active roller, respectively, a plurality of guide grooves A and B evenly spaced on the upper surfaces of guide plate A and guide groove B, and a cutting cylinder fixedly mounted on the upper surface of the fixed frame above guide plate B, with a cutting blade fixedly connected to the output end of the cutting cylinder.

[0006] Preferably, an electric push rod is fixedly installed on the upper surface of the fixed frame at a position above the driven roller, and a lifting frame is fixedly connected to the output end of the electric push rod. The lifting frame is located inside the fixed frame, and the driven roller is rotatably installed inside the lifting frame.

[0007] Preferably, guide sliders are fixedly installed on both sides of the outer surface of the lifting frame, and guide grooves are symmetrically provided on both sides of the outer surface of the fixed frame, with the two guide sliders located inside the two guide grooves respectively.

[0008] Preferably, a rotating motor is fixedly installed on one side of the outer surface of the fixed frame, and the end of the output shaft of the rotating motor is fixedly connected to the end of the drive roller.

[0009] Preferably, guide slide rods are symmetrically fixedly connected to both sides of the upper surface of the cutting blade, and sliding sleeves are symmetrically fixedly installed on the upper surface of the fixing frame at both sides of the cutting cylinder, with the two guide slide rods passing through the two sliding sleeves respectively.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by setting up a fixed frame, a driving roller, an annular groove, a driven roller, a pressure ring, a guide plate A, a guide groove A, a guide plate B, and a guide groove B, achieves the effect of guiding the sliver before and after conveying, and limiting the sliver during the conveying process, effectively preventing loose sliver from adhering to the roller, thereby improving the cutting efficiency. The sliver first passes through the inside of the guide groove A, and then through the inside of the annular groove. The sliver inside the annular groove is subjected to the pressure of the pressure ring, so when the driving roller rotates, it can drive the sliver to move, thereby achieving the purpose of conveying the sliver. During the conveying process, the sliver is restricted inside the annular groove, which can effectively prevent the sliver from adhering to the driving roller. After conveying, the sliver passes through the inside of the guide groove B, and the cutting cylinder drives the cutting blade to descend, completing the cutting of the sliver.

[0012] 2. This utility model achieves the effect of facilitating the transmission of wool strips of different thicknesses by setting an electric push rod and a lifting frame. The electric push rod drives the driven roller to rise and fall through the lifting frame. By adjusting the depth of the pressure ring inserted into the annular groove, it is possible to control the passage and transmission of wool strips of different thicknesses through the annular groove.

[0013] 3. By setting guide grooves and guide sliders, this utility model plays a guiding and limiting role in the lifting of the lifting frame, thereby improving the stability of the lifting frame. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] like Figures 1-4 As shown, this utility model proposes a sliver cutting device to prevent sliver from getting tangled in the sliver roller. The device includes a fixed frame 1, which is through-type and has a U-shape. A drive roller 9 is rotatably mounted inside the fixed frame 1. The two ends of the drive roller 9 are rotatably connected to the fixed frame 1 via bearings. A rotary motor 8 is fixedly mounted on one side of the outer surface of the fixed frame 1. The output shaft of the rotary motor 8 is fixedly connected to the end of the drive roller 9. The outer surface of the drive roller 9 has several annular grooves 10 evenly spaced. A driven roller 11 is positioned above the drive roller 9 inside the fixed frame 1. A pressure ring 12 is fixedly fitted onto the outer surface of the driven roller 11 at each annular groove 10. Guide plates A3 and B17 are fixedly mounted in front of and behind the drive roller 9, respectively. The upper surfaces of guide plates A3 and B17 are evenly spaced... Several guide grooves A2 and B18 are provided, each corresponding to an annular groove 10. A cutting cylinder 5 is fixedly installed on the upper surface of the fixing frame 1 above the guide plate B17, and a cutting blade 16 is fixedly connected to the output end of the cutting cylinder 5. A connecting groove is provided on the upper surface of the guide plate B17 below the cutting blade 16, so that after the cutting blade 16 descends, its blade edge can enter the guide groove B18 and cut the sliver. Guide slide rods 6 are symmetrically fixedly connected to both sides of the upper surface of the cutting blade 16. Sliding sleeves 7 are symmetrically fixedly installed on both sides of the upper surface of the fixing frame 1, and the two guide slide rods 6 pass through the two sliding sleeves 7 respectively. The sliding sleeves 7 and the guide slide rods 6 guide the lifting and lowering of the cutting blade 16, improving the stability of the cutting blade 16.

[0022] In use, the wool strip first passes through the guide groove A2 and then through the annular groove 10. The wool strip inside the annular groove 10 is subjected to the pressure of the pressure ring 12. When the drive roller 9 rotates, it can drive the wool strip to move, so as to achieve the purpose of conveying the wool strip. During the conveying process, the wool strip is restricted inside the annular groove 10, which can effectively prevent the wool strip from adhering to the drive roller 9. After being conveyed, the wool strip passes through the guide groove B18. The cutting cylinder 5 drives the cutting blade 16 to descend and completes the cutting of the wool strip.

[0023] Example 2

[0024] like Figures 1-4 As shown, the present invention proposes a sliver cutting device that can prevent sliver from getting tangled in the sliver roller. Compared with the first embodiment, this embodiment further includes an electric push rod 4 fixedly installed on the upper surface of the fixed frame 1 above the driven roller 11. The output end of the electric push rod 4 is fixedly connected to a lifting frame 13. The lifting frame 13 is shaped like an "n" in front of view. The lifting frame 13 is located inside the fixed frame 1, and the driven roller 11 is rotatably installed inside the lifting frame 13. The two ends of the driven roller 11 and the lifting frame 13 are rotatably connected by bearings. Guide sliders 15 are fixedly installed on both sides of the outer surface of the lifting frame 13. Guide grooves 14 are symmetrically provided on both sides of the outer surface of the fixed frame 1, and the two guide sliders 15 are respectively located inside the two guide grooves 14. The guide grooves 14 and the guide sliders 15 play a guiding and limiting role in the lifting and lowering of the lifting frame 13, thereby improving the stability of the lifting frame 13.

[0025] In this embodiment, the electric push rod 4 drives the driven roller 11 to rise and fall through the lifting frame 13, and the depth of the pressure ring 12 inserted into the annular groove 10 can be adjusted to control the flow of different thicknesses of wool strips through and be conveyed inside the annular groove 10.
