In the spinning process of the textile industry, the drawing frame is the core equipment that combines multiple fiber slivers and drafts them into a uniform sliver. Its performance directly determines the yarn quality and production efficiency.

[0003] Among them, the drawing mechanism of a drawing frame with announcement number CN222362208U includes a frame, on which multiple lower rollers are rotatably connected, and above each lower roller, an upper roller is rotatably connected to cooperate with it. Each lower roller and each upper roller is driven to rotate by the drive assembly of the drawing frame. A V-shaped hub is provided on one side of the lower rollers on the frame. The opening of the V-shaped hub is obliquely upward facing the lower rollers. The tail end of the V-shaped hub is connected to a guide tube. A winding tube is rotatably connected to the frame below the guide tube. The inner wall of the winding tube is provided with multiple helical blades. The winding tube is driven to rotate axially by the drive assembly of the drawing frame.

[0004] However, the outlet of existing drawing frames is usually fixed, so when there are too many yarns to be drawn, the yarns may become clogged, requiring workers to clean them, which greatly reduces the working efficiency of the drawing frame. Utility Model Content

[0005] In view of the problems existing in the drawing mechanism of the existing drawing frame machine, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide an adjustable drawing frame mechanism, which solves the problem that the outlet of existing drawing frames is usually fixed, so when too much yarn needs to be drawn, the yarn may become clogged, requiring workers to clean it, which greatly reduces the working efficiency of the drawing frame.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An adjustable drawing frame mechanism includes a base with a cavity inside. Two strip-shaped holes are formed on the upper surface of the cavity. Support rods are slidably disposed inside each of the two strip-shaped holes. Sleeves are rotatably fitted onto the walls of each support rod. Guide rollers are fixedly connected to the outer surfaces of each sleeve. An adjustment mechanism is provided inside the cavity. The two support rods move through the adjustment mechanism.

[0009] Preferably, the adjustment mechanism includes two first trapezoidal blocks, a second trapezoidal block, two T-shaped blocks, and a cylinder. The two first trapezoidal blocks are slidably disposed inside corresponding cavities and fixedly connected to the lower end of the support rod. The inclined surfaces of the two first trapezoidal blocks are provided with T-shaped grooves. The two T-shaped blocks are slidably disposed inside the T-shaped grooves. The second trapezoidal block is fixedly connected between the two T-shaped blocks. The cylinder is fixedly connected to the lower surface of the base. The output end of the cylinder passes through the lower surface of the base and is fixedly connected to the lower surface of the second trapezoidal block.

[0010] Preferably, the drive mechanism includes two motors, two first gears and two second gears. The two motors are respectively fixedly connected to one side of the corresponding first trapezoidal block. The two first gears are respectively fixedly sleeved on the output end of the corresponding motor. The two second gears are respectively fixedly sleeved on the outer surface of the corresponding sleeve and mesh with the first gear.

[0011] Preferably, the limiting mechanism includes two limiting plates and an extension plate.

[0012] Preferably, both ends of the cavity are provided with sliding grooves, and limit blocks are slidably arranged inside the two sliding grooves. Each limit block is fixedly connected to one side of the corresponding first trapezoidal block.

[0013] Preferably, the outer surfaces of both guide rollers are provided with grooves.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model uses a cylinder to drive the second trapezoidal block and the T-shaped block, which in turn moves the first trapezoidal block and the support rod, precisely adjusting the distance between the two guide rollers. This allows for flexible adaptation to different quantities of yarn drawing requirements, avoiding yarn blockage caused by a fixed outlet, reducing the frequency of manual cleaning, and significantly improving the working efficiency of the drawing frame.

[0016] 2. In this utility model, the two guide rollers are driven by independent motors, a first gear, and a second gear, enabling them to rotate at the same speed or differential speed to meet different drafting process requirements. The limiting block and the sliding groove cooperate to ensure smooth movement of the guide rollers and avoid tilting. Combined with the annular groove on the outer surface of the guide rollers, the yarn is effectively concentrated to prevent deviation or tangling, ensuring the uniformity and stability of the drawing.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses an adjustable drawing frame mechanism.

[0025] This utility model provides, for example Figure 1-3An adjustable drawing frame mechanism is shown, comprising a base 1, with a cavity inside the base 1. Two strip-shaped holes are formed on the upper surface of the cavity. Support rods 2 are slidably arranged inside the two strip-shaped holes. Sleeves 3 are rotatably sleeved on the walls of the two support rods 2. Guide rollers 4 are fixedly connected to the outer surfaces of the two sleeves 3. An adjustment mechanism is provided inside the cavity. The two support rods 2 move through the adjustment mechanism. A drive mechanism is provided on one side of each of the two adjustment mechanisms. The two sleeves 3 rotate through their respective drive mechanisms. A limit mechanism is fixedly connected to the upper ends of the two support rods 2.

[0026] By moving the support rod 2 left and right, the distance between the two guide rollers 4 can be changed, thus enabling the equipment to be used for drawing different amounts of yarn.

[0027] In order to move the two guide rollers 4, such as Figure 1-3 As shown, the adjustment mechanism includes two first trapezoidal blocks 5, a second trapezoidal block 6, two T-shaped blocks 7, and a cylinder 8. The two first trapezoidal blocks 5 are slidably disposed inside the corresponding cavities and fixedly connected to the lower end of the support rod 2. The inclined surfaces of the two first trapezoidal blocks 5 are provided with T-shaped grooves. The two T-shaped blocks 7 are slidably disposed inside the T-shaped grooves. The second trapezoidal block 6 is fixedly connected between the two T-shaped blocks 7. The cylinder 8 is fixedly connected to the lower surface of the base 1. The output end of the cylinder 8 passes through the lower surface of the base 1 and is fixedly connected to the lower surface of the second trapezoidal block 6. Sliding grooves are provided at both ends of the cavities. Limiting blocks 14 are slidably disposed inside the two sliding grooves. Each limiting block 14 is fixedly connected to one side of the corresponding first trapezoidal block 5.

[0028] After cylinder 8 starts, the output end pushes the second trapezoidal block 6 upward, and the two T-shaped blocks 7 slide along the T-groove of the first trapezoidal block 5, causing the two first trapezoidal blocks 5 to move outward. The support rod 2 rises with the first trapezoidal blocks, widening the gap between the guide rollers 4. When the cylinder retracts, the first trapezoidal blocks fall back under gravity, narrowing the gap. The guide of the limiting block 14 and the slide groove ensures smooth movement and avoids tilting.

[0029] In order to make the two guide rollers 4 rotate, such as Figure 2 As shown, the drive mechanism includes two motors 9, two first gears 10 and two second gears 11. The two motors 9 are respectively fixedly connected to one side of the corresponding first trapezoidal block 5. The two first gears 10 are respectively fixedly sleeved on the output end of the corresponding motor 9. The two second gears 11 are respectively fixedly sleeved on the outer surface of the corresponding sleeve 3 and mesh with the first gears 10.

[0030] Motor 9 drives the first gear 10 to rotate, which in turn meshes with the second gear 11 to drive the sleeve 3 and the guide roller 4 to rotate. The two guide rollers are controlled by independent motors, which can achieve rotation at the same speed or differential speed to meet different drawing process requirements.

[0031] To prevent the yarn threads from flying off, such as Figure 1-2 As shown, the limiting mechanism includes two limiting plates 12 and an extension plate 13. The two limiting plates 12 are respectively fixedly connected to the upper end of the corresponding support rod 2. A flower cluster is opened on one side of one of the limiting plates 12. The extension plate 13 is slidably disposed inside the slide groove and fixedly connected to one end of the other extension plate 13. The outer surfaces of the two guide rollers 4 are all surrounded by grooves.

[0032] The annular groove can be used to concentrate the moving yarn, while the two limiting plates 12 and the extension plate can prevent the yarn from slipping out of the guide roller.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
