Description

Technical Field

[0001] This utility model belongs to the field of chemical fiber production technology, and specifically relates to a spinneret clamp that is easy to replace. Background Technology

[0002] The spinneret, also known as the spinning cap, is used to transform viscous polymer melts or solutions into fine streams with specific cross-sectional shapes through micropores. These streams are then solidified by a solidification medium such as air or a solidification bath to form filaments. Spinneret clamps are tools used to hold the spinneret. However, traditional spinneret clamps usually rely on manual disassembly, often requiring the use of tools such as wrenches. If the tools slip, they may damage the clamp surface or the edge of the spinneret. The operation is cumbersome and time-consuming, requiring operators to repeatedly adjust the tightness of each clamp. Uneven force can easily lead to spinneret displacement or wear of the clamping surface. Furthermore, under long-term equipment vibration or temperature fluctuations, the clamping surface is prone to gradually losing pre-tightness due to material fatigue or stress relaxation, resulting in micro-displacement between the spinneret and the clamp. This loosening phenomenon can directly cause the spinneret orifice to shift, resulting in uneven spinning fineness, filament breakage, or forming defects. To solve the problems mentioned above, we propose a spinneret clamp that is easy to replace. Utility Model Content

[0003] The purpose of this utility model is to provide a spinneret clamp that is easy to replace, which has the advantages of stable and uniform clamping and preventing loosening.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a spinneret clamp that is easy to replace, comprising a movable plate, a sliding sleeve bolted to the top and bottom of the movable plate, a sliding rod slidably sleeved inside the sliding sleeve, a fixed plate bolted to the two sliding rods on opposite sides away from the middle, a clamping block bolted to the left side of the fixed plate opposite to the movable plate, a limiting groove bolted to the right side of the movable plate, a limiting block slidably connected inside the limiting groove, a threaded sleeve bolted to the right side of the limiting block, a screw threadedly connected inside the threaded sleeve, a back plate bolted to the right side of the sliding rod, and a locking mechanism provided on the left side of the sliding rod surface.

[0005] The above technical solution involves the following: the screw rotation drives the screw sleeve to move backward, the screw sleeve movement drives the limiting block to move, and the limiting block moves along the path inside the limiting groove. The limiting block and the limiting groove are set as inclined surfaces. The backward movement of the limiting block uniformly compresses the limiting groove. The compression of the limiting groove drives the moving plate to move to the left. The sliding sleeve limits the movement of the moving plate. The movement of the moving plate drives the clamping block to clamp the spinneret. Rotating the screw can make the clamping block move centripetally, uniformly clamping the spinneret, ensuring stable force and excellent centering. When replacement is required, simply rotate the screw in the opposite direction to make the clamping block move backward synchronously away from the edge of the spinneret. The operation process is intuitive and simple. This structure not only significantly shortens the disassembly and installation time and significantly improves the changeover efficiency, but also minimizes the labor intensity of operators while ensuring stable clamping, reducing the risk of misoperation caused by tool use or complex steps.

[0006] The present invention is further configured such that the locking mechanism includes a fixing block, the fixing block is fixedly sleeved on the left side of the slide rod surface, a bracket is bolted to the front of the fixing block, a spring is bolted to the right side of the bracket, a fixing sleeve is bolted to the right side of the spring, a fixing post is bolted to the front of the slide sleeve, and the surface of the fixing post is sleeved with the inside of the fixing sleeve.

[0007] The above technical solution employs a locking mechanism. By gripping and pulling the fixing sleeve, the fixing sleeve stretches the spring, allowing the fixing sleeve to fit into the fixing post. The spring then contracts and tightens, preventing the clamping block from loosening. After the clamping block has finished clamping the spinneret, it can be locked, completely eliminating the risk of loosening caused by equipment vibration or external impact. This maintains high-precision alignment between the spinneret and the fixture contact surface, ensuring no displacement or deflection during processing. The design, which eliminates the need for frequent manual re-tightening, significantly reduces operational intervention, improving the stability of continuous production and reducing problems such as spinneret damage or spinning quality fluctuations caused by loosening.

[0008] The present invention is further configured such that a slider is bolted to the right side of the screw sleeve, and a groove is provided on the left side of the right fixed plate, and the interior of the groove is slidably connected to the surface of the slider.

[0009] The above technical solution uses a slider and a groove to limit the movement of the threaded sleeve.

[0010] The present invention is further configured such that the interior of the limiting groove and the left side of the limiting block are inclined surfaces.

[0011] The above technical solution is adopted: by setting it as an inclined surface, when the limiting block moves to uniformly squeeze the limiting groove, the limiting groove is squeezed and drives the moving plate to move. Because it is set as an inclined surface, the movement can be more uniform.

[0012] The present invention is further configured such that a bearing is rotatably connected to the back of the screw.

[0013] The above technical solution utilizes bearings to stabilize the screw.

[0014] The present invention is further configured such that a turntable is fixedly sleeved on the front side of the screw.

[0015] The above technical solution utilizes a turntable to facilitate the rotation of the screw.

[0016] The present invention is further configured such that a base is bolted to the bottom of the back plate.

[0017] The above technical solution utilizes a base to stabilize the mechanism.

[0018] The present invention is further provided that an anti-slip pad is bonded to the middle of the opposite sides of the two clamping blocks.

[0019] The above technical solution, by setting anti-slip pads, can prevent the clamped spinneret from slipping.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. This utility model allows the clamping blocks to move centripetally by rotating the screw, applying force evenly to clamp the spinneret, ensuring stable force and excellent centering. When replacement is needed, simply rotate the screw in the opposite direction to allow the clamping blocks to move backward synchronously away from the edge of the spinneret. The operation process is intuitive and simple. This structure not only significantly shortens the disassembly and installation time and greatly improves the efficiency of changeover, but also minimizes the labor intensity of operators while ensuring stable clamping, and reduces the risk of misoperation caused by tool use or complex steps.

[0022] 2. This utility model locks the clamping block after it has clamped the spinneret, completely eliminating the risk of loosening caused by equipment vibration or external impact. It maintains high-precision alignment between the spinneret and the clamping surface, ensuring no displacement or deflection during processing. Its design, which eliminates the need for frequent manual re-tightening, significantly reduces operational intervention, improving the stability of continuous production and reducing problems such as spinneret damage or spinning quality fluctuations caused by loosening.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example 1:

[0029] refer to Figure 1 , Figure 2 , Figure 3 A replaceable spinneret clamp includes a movable plate 1, with sliding sleeves 2 bolted to the top and bottom of the movable plate 1. A sliding rod 3 is slidably connected inside the sliding sleeve 2. Fixed plates 4 are bolted to the two sliding rods 3 facing each other and on opposite sides away from the center. A clamping block 5 is bolted to the left side of the fixed plate 4 opposite to the movable plate 1. A limiting groove 6 is bolted to the right side of the movable plate 1. A limiting block 7 is slidably connected inside the limiting groove 6. A threaded sleeve 8 is bolted to the right side of the limiting block 7. A screw 9 is threadedly connected inside the threaded sleeve 8. A back plate 10 is bolted to the right side of the sliding rod 3. A locking mechanism is provided on the left side of the surface of the sliding rod 3. Rotation of the screw 9 drives the threaded sleeve 8 to... The screw sleeve 8 moves backward, driving the limiting block 7 to move. The limiting block 7 moves along the path inside the limiting groove 6. The limiting block 7 and the limiting groove 6 are set as inclined surfaces. The limiting block 7 moves backward to uniformly squeeze the limiting groove 6. The limiting groove 6 is squeezed, causing the moving plate 1 to move to the left. The sliding sleeve 2 limits the movement of the moving plate 1. The movement of the moving plate 1 drives the clamping block 5 to clamp the spinneret. Rotating the screw 9 can make the clamping block 5 move centripetally, uniformly applying force to clamp the spinneret, ensuring stable force and excellent centering. When replacement is needed, simply rotate the screw 9 in the opposite direction to make the clamping block 5 move backward synchronously away from the edge of the spinneret. The operation process is intuitive and simple.

[0030] refer to Figure 3 A slider 16 is bolted to the right side of the screw sleeve 8, and a groove 17 is provided on the left side of the right fixed plate 4. The inside of the groove 17 is slidably connected to the surface of the slider 16. By setting the slider 16 and the groove 17, the movement of the screw sleeve 8 can be limited.

[0031] refer to Figure 2 , Figure 3 The inside of the limiting groove 6 and the left side of the limiting block 7 are set as inclined surfaces. By setting them as inclined surfaces, when the limiting block 7 moves to uniformly squeeze the limiting groove 6, the limiting groove 6 is squeezed and drives the moving plate 1 to move. Because it is set as an inclined surface, it can move more evenly.

[0032] refer to Figure 3 A bearing 18 is rotatably connected to the back of the screw 9, and the screw 9 can be stabilized by the bearing 18.

[0033] refer to Figure 1 A turntable 19 is fixedly sleeved on the front of the screw 9, which allows the screw 9 to be rotated easily.

[0034] refer to Figure 1 , Figure 2 , Figure 3 The bottom of the back plate 10 is bolted with a base 20, which can stabilize the mechanism.

[0035] refer to Figure 1 , Figure 2 , Figure 3 An anti-slip pad 21 is glued to the middle of the two clamping blocks 5 on opposite sides. By setting the anti-slip pad 21, the clamped spinneret can be prevented from slipping.

[0036] Brief description of usage: When clamping the spinneret is required, rotating the turntable 19 drives the screw 9 to rotate. The rotation of the screw 9 causes the screw sleeve 8 to move backward. The slider 16 and the slide groove 17 limit the movement of the screw sleeve 8. The movement of the screw sleeve 8 causes the limiting block 7 to move. The limiting block 7 moves along the path inside the limiting groove 6. The limiting block 7 and the limiting groove 6 are set as inclined surfaces. The backward movement of the limiting block 7 uniformly compresses the limiting groove 6. The compression of the limiting groove 6 causes the moving plate 1 to move to the left. The slider 2 limits the movement of the moving plate 1. The moving clamping block 5 clamps the spinneret, and rotating the screw 9 causes the clamping block 5 to move centripetally, applying force evenly to clamp the spinneret, ensuring stable force and excellent centering. When replacement is needed, simply rotate the screw 9 in the opposite direction to allow the clamping block 5 to move backward and detach from the edge of the spinneret. The operation is intuitive and simple. This structure not only significantly shortens the disassembly and installation time and greatly improves the efficiency of changeover, but also minimizes the labor intensity of operators while ensuring stable clamping, reducing the risk of misoperation caused by tool use or complex procedures.

[0037] Example 2:

[0038] refer to Figure 1 , Figure 2A replaceable spinneret clamp has a locking mechanism including a fixing block 11, which is fixedly sleeved on the left side of the slide bar 3. A bracket 12 is bolted to the front of the fixing block 11, and a spring 13 is bolted to the right side of the bracket 12. A fixing sleeve 14 is bolted to the right side of the spring 13. A fixing post 15 is bolted to the front of the slide bar 2, and the surface of the fixing post 15 is sleeved with the inside of the fixing sleeve 14. When the fixing sleeve 14 is gripped and pulled, the fixing sleeve 14 causes the spring 13 to stretch, and the fixing sleeve 14 is put into the fixing post 15. The spring 13 contracts and tightens, which can prevent the clamping block 5 from loosening. After the clamping block 5 has finished clamping the spinneret, the clamping block 5 can be locked, completely eliminating the risk of clamping loosening caused by equipment vibration or external impact.

[0039] Brief description of the usage process: After the spinneret is clamped, hold the fixing sleeve 14 and pull it. The fixing sleeve 14 drives the spring 13 to stretch, and the fixing sleeve 14 is put into the fixing post 15. The spring 13 contracts and tightens, which can prevent the clamping block 5 from loosening. After the clamping block 5 has completed clamping the spinneret, the clamping block 5 can be locked, completely eliminating the risk of clamping loosening caused by equipment vibration or external impact. It maintains high-precision alignment between the spinneret and the contact surface of the fixture, ensuring no displacement or deflection during processing. Its design that does not require frequent manual re-tightening significantly reduces operational intervention, which not only improves the stability of continuous production, but also reduces problems such as spinneret damage or spinning quality fluctuations caused by loosening.
