Detailed Implementation

[0018] To enhance understanding of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described and introduced below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this utility model, not all embodiments, and are not intended to limit the embodiments in any way. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] Please see Figure 1-6 This utility model provides a technical solution: a flax combing machine drawing head with adjustable limits, comprising a first drawing roller 1 and a second drawing roller 2. The first drawing roller 1 and the second drawing roller 2 cooperate to apply different pressures to the flax thread. The first drawing roller 1 consists of a first roller 101, a first connecting wheel 102, and a first rubber ring 103. The second drawing roller 2 consists of a second roller 201, a second connecting wheel 202, a guide wheel 203, and a second rubber ring 204. The first drawing roller 1 has a central... There is a traction plate 5, and a fixed protrusion 9 for controlling the tension of the first rubber ring 103 is fixedly connected between the two traction plates 5. A fixing member 11 is provided in the middle of the second drawing roller 2. A groove is provided at the upper end of the fixing member 11. A lifting plate 4 for squeezing the second rubber ring 204 is slidably connected in the groove. The lifting plate 4 controls the second rubber ring 204 to apply different forces to the hemp thread. An adjusting screw 12 is rotatably connected in the middle of the fixing member 11. A moving block 13 for changing the height of the lifting plate 4 is threadedly connected in the middle of the adjusting screw 12.

[0020] The lower end of the first drafting roller 1 and the upper end of the second drafting roller 2 are both horizontal structures. The upper end of the lifting plate 4 abuts against the inner wall of the second rubber ring 204. The middle of the upper end of the lifting plate 4 is horizontal, and both sides of the upper end of the lifting plate 4 are arc-shaped structures. The lifting plate 4 can lift the second rubber ring 204 to prevent the second rubber ring 204 from shaking when it is working. When the lifting plate 4 moves upward, it can tension the second rubber ring 204, thereby changing the pressure between the first rubber ring 103 and the second rubber ring 204.

[0021] The movable block 13 and the fixing member 11 are slidably connected. The lifting plate 4 has a T-shaped structure. The lower end of the lifting plate 4 and the upper end of the movable block 13 are hinged to a linkage rod 14. The linkage rod 14 is inclined. By rotating the adjusting screw, the adjusting screw 12 can drive the movable block 13 to move horizontally. The movable block 13 drives the lifting plate 4 to move up and down through the linkage rod 14, thereby changing the tension of the second rubber ring 204 and applying different pressures to the fibers.

[0022] Both sides of the first connecting wheel 102 are provided with cover plates 6. The side ends of the cover plates 6 are rotatably connected to the traction plate 5. The middle of the traction plate 5 is threaded with a fixing bolt 8. The two ends of the fixing bolt 8 pass through the traction plate 5. The side ends of the cover plates 6 are provided with scales. The upper end of the traction plate 5 is fixedly connected with a handle 3. The lower side wall of the traction plate 5 is fixedly connected with a pointer 7. The handle 3 drives the traction plate 5 to rotate, changing the angle between the traction plate 5 and the fixed protrusion 9. The pointer 7 can change the size of the angle pointing to the traction plate 5.

[0023] The side end of the fixed protrusion 9 has an arc-shaped structure, and a tension wheel 10 is embedded in the middle of the fixed protrusion 9. The side end of the tension wheel 10 abuts against the inner wall of the first rubber ring 103. When the traction plate 5 and the fixed protrusion 9 rotate, the tension wheel 10 can squeeze the inner wall of the first rubber ring 103, thereby tensioning the first rubber ring 103 and preventing the first rubber ring 103 from shaking.
