Description

Technical Field

[0001] This utility model relates to the field of novel coiling blade technology, specifically to a novel coiling blade feed structure. Background Technology

[0002] The crimping machine is a key piece of equipment in the post-processing production line of chemical fiber staple fibers. Based on the mechanical crimping principle, it crimps and deforms the chemical fiber staple fiber bundles. Most crimping machines currently in use are box-type, divided into horizontal and vertical types. The main components include the crimping box component, the crimping roller component, and the pressure component. Among them, the width of the crimping box and the crimping roller determines the production capacity of the crimping machine. The development of crimping machines has gone through a process from mechanical to hydraulic, and then to CNC. In the early days, crimping machines faced high technical barriers and relied on imports. However, with the introduction of technology and independent innovation, domestic equipment has made breakthroughs in technology and has effectively replaced imported products in terms of market share.

[0003] Currently, most crimping machines on the market use plunger cylinders as the main back pressure method. However, the piston rod seal of the plunger cylinder is prone to damage. Due to the limitations of the cylinder structure, air leakage and pressure loss are likely to occur during actual use, which directly affects the quality of the filament. The movement trajectory of the crimping roller and the back pressure is an arc curve, while the piston rod moves in a straight reciprocating motion. This design mismatch causes the piston rod of the plunger cylinder to react slowly when the pulp block in the filament passes through. The gap between the upper and lower crimping knives and the crimping roller is adjusted by 0.2-0.5mm. After the knife tips are aligned, the fixed knife block is locked, the inclined block is pressed, and the bolts are tightened. Each adjustment requires an experienced maintenance technician to work for more than ten minutes, which affects production efficiency. When filament is caught in the gap between the crimping roller and the crimping knife, the fastening bolts of the crimping knife need to be loosened to remove the caught filament. Then, the gap between the crimping knife and the crimping roller needs to be readjusted and fixed. Utility Model Content

[0004] This utility model proposes a novel feed structure for a coiling cutter, which solves the problems mentioned in the above documents.

[0005] The technical solution of this utility model is as follows: a novel curling knife feeding structure includes a protective plate, a curling roller is provided on the top of the protective plate, and a curling knife is provided on the top of the protective plate;

[0006] An adjustment device is provided on the top of the protective plate. The adjustment device includes a fixing plate, which is fixedly connected to the top of the protective plate. A linear track bearing seat is fixedly connected to the top of the fixing plate. A guide rail is slidably connected to the side of the linear track bearing seat. A screw is provided on the side of the linear track bearing seat. A nut is threaded onto the circumferential surface of the screw. A positioning groove pressure block is provided on the side of the linear track bearing seat.

[0007] The screws are arranged in pairs, symmetrically arranged along the vertical central axis of the protective plate. By loosening the screws of the positioning slot pressure block, the curling knife can be quickly pulled backward to clean up the waste wires before tightening the screws.

[0008] The side of the guide rail is fixedly connected to the side of the curling cutter. The number of nuts is set to several, in pairs, and symmetrical to each other along the vertical central axis of the protective plate. After the curling cutter is fixed to the linear track bearing seat, the curling cutter can move freely back and forth, but will not move left and right. This ensures the stability of the cutter during operation, avoids the wobble or positional deviation of the cutter, and thus improves the machining accuracy.

[0009] The top of the protective plate is provided with a detachable device, which includes a mounting plate. The mounting plate is disposed on the side of the curling knife. A support rod is fixedly connected to the side of the mounting plate. A fixing block is fixedly connected to one end of the support rod. A positioning plate is fixedly connected to the side of the fixing plate. A protective shell is fixedly connected to the side of the positioning plate. A fixing rod passes through the side of the protective shell. A disc is fixedly connected to one end of the fixing rod. A locking block is fixedly connected to the other end of the disc.

[0010] A spring is fixedly connected to the circumferential surface of the support rod. The end of the spring away from the support rod is fixedly connected to the side of the guide rail. The spring design allows the mounting plate to automatically reset, reducing manual intervention.

[0011] The spring is initially in a relaxed state. The locking block is located on the movement trajectory of the fixed block. Through the cooperation of the locking block and the action of the return spring, the fixed block can stably fix the mounting plate and the curling blade, ensuring that the curling blade does not shift or loosen during operation.

[0012] A return spring is fixedly connected to the circumferential surface of the fixing rod. The end of the return spring away from the fixing rod is fixedly connected to the side of the protective shell. The design of the return spring can make the locking block automatically reset, reducing manual intervention.

[0013] The initial state of the return spring is relaxed. The number of support rods is set to several, in pairs, and symmetrical to each other along the vertical central axis of the mounting plate. The design of the support rods can fix the curling cutter in place by the mounting plate, making it easy to replace the cutter and saving time and labor costs.

[0014] The curling blade is located on the movement trajectory of the mounting plate, and the number of protective shells is set to several, in pairs, and symmetrical to each other along the vertical central axis of the mounting plate. This structural design makes the installation and disassembly of the curling blade simpler and more efficient, reduces downtime, and improves the working efficiency of the production line.

[0015] The side of the clamping block is set as an inclined surface, and the side of the fixing block is set as an inclined surface. The displacement of the fixing block and the clamping block is controlled by pulling the support rod or the disc, so as to realize the quick disassembly or replacement of the curling knife.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] 1. In this utility model, by fixing the curling knife and the linear guide rail with the positioning groove pressure block, linear track bearing seat and nut in the adjustment device, the problem of quick handling of wire clamping between the knife and the roller during production is not only solved, but also the tedious and meticulous start-up preparation work of adjusting the gap between the curling knife and the curling roller is eliminated. The process is fast and simple, which greatly improves the efficiency of cleaning waste wire and reduces downtime caused by waste wire blockage.

[0018] 2. In this utility model, the force that causes the support rod to move the mounting plate by pulling the support rod cooperates with the reset spring, positioning block, and fixing block in the detachable device. This allows the sliding rod to drive the locking block to reset through the elastic force of the reset spring when the fixing block moves to the side of the locking block, thus locking the mounting plate and fixing the curling blade. This achieves the effect of a detachable curling blade, making it easy to replace the blade and saving time and labor costs. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1

[0028] like Figures 1-5 As shown, this embodiment proposes a novel curling blade feeding structure, including a protective plate 101, a curling roller 102 disposed on the top of the protective plate 101, and a curling blade 103 disposed on the top of the protective plate 101.

[0029] An adjustment device 2 is provided on the top of the protective plate 101. The adjustment device 2 includes a fixing plate 201, which is fixedly connected to the top of the protective plate 101. A linear track bearing seat 202 is fixedly connected to the top of the fixing plate 201. A guide rail 203 is slidably connected to the side of the linear track bearing seat 202. A screw 205 is provided on the side of the linear track bearing seat 202. A nut 206 is threaded onto the circumferential surface of the screw 205. A positioning groove pressure block 204 is provided on the side of the linear track bearing seat 202.

[0030] The number of screws 205 is set to several, in pairs, and symmetrical to each other along the vertical central axis of the protective plate 101. By loosening the screws 205 of the positioning slot pressure block 204, the curling knife 103 can be quickly pulled backward to clean up the waste wires before tightening the screws 205.

[0031] The side of the guide rail 203 is fixedly connected to the side of the curling cutter 103. The number of nuts 206 is set to several, in pairs, and symmetrical to each other along the vertical central axis of the protective plate 101. After the curling cutter 103 is fixed to the linear track bearing seat 202, the curling cutter 103 can move freely back and forth, but will not move left and right. This ensures the stability of the cutter during operation, avoids the wobble or positional deviation of the cutter, and thus improves the machining accuracy.

[0032] In this embodiment, the machining ensures the perpendicularity of the mounting groove of the linear track bearing seat 202 to the curling roller 102 meets the accuracy requirements. After the linear track bearing seat 202 is fixed and locked, the curling knife 103 is then fixed to the linear track bearing seat 202. After the two are combined, the curling knife 103 does not move left or right and can move freely back and forth. After the knife tip contacts the curling roller 102, the fine-tooth stud of the positioning groove pressure block 204 is adjusted to push the curling knife 103 away from the curling roller 102 by 0.2-0.5mm. Then, the screw 205 of the positioning groove pressure block 204 is tightened to press and fix the curling knife 103. When wire jamming occurs, only the screw 205 is loosened, the curling knife 103 is pulled back to clean the waste wire, and then the screw 205 is tightened again to quickly complete the cleaning work, greatly improving production efficiency.

[0033] Example 2

[0034] like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, a second embodiment is also proposed. A detachable device 3 is provided on the top of the protective plate 101. The detachable device 3 includes a mounting plate 301, which is disposed on the side of the curling blade 103. A support rod 302 is fixedly connected to the side of the mounting plate 301. A fixing block 304 is fixedly connected to one end of the support rod 302. A positioning plate 305 is fixedly connected to the side of the fixing plate 201. A protective shell 306 is fixedly connected to the side of the positioning plate 305. A fixing rod 307 passes through the side of the protective shell 306. A disc 309 is fixedly connected to one end of the fixing rod 307. A locking block 310 is fixedly connected to the other end of the disc 309.

[0035] A spring 303 is fixedly connected to the circumferential surface of the support rod 302. The end of the spring 303 away from the support rod 302 is fixedly connected to the side of the guide rail 203. The design of the spring 303 can enable the mounting plate 301 to automatically reset, reducing manual intervention.

[0036] The initial state of the spring 303 is relaxed. The locking block 310 is located on the movement trajectory of the fixing block 304. Through the cooperation of the fixing block 304 with the locking block 310 and the action of the return spring 308, the mounting plate 301 and the curling blade 103 can be stably fixed to ensure that the curling blade 103 does not shift or loosen during operation.

[0037] A return spring 308 is fixedly connected to the circumferential surface of the fixing rod 307. The end of the return spring 308 away from the fixing rod 307 is fixedly connected to the side of the protective shell 306. The design of the return spring 308 can make the locking block 310 automatically reset, reducing manual intervention.

[0038] The initial state of the return spring 308 is relaxed. The number of support rods 302 is set to several, in pairs, and symmetrical to each other along the vertical central axis of the mounting plate 301. The design of the support rods 302 can fix the mounting plate 301 to the coiling cutter 103, making it easy to replace the cutter and saving time and labor costs.

[0039] The coiling blade 103 is located on the movement trajectory of the mounting plate 301. The number of protective shells 306 is set to several, in pairs, and symmetrical to each other along the vertical central axis of the mounting plate 301. This structural design makes the process of installing and disassembling the coiling blade 103 simpler and more efficient, reduces downtime, and improves the working efficiency of the production line.

[0040] The side of the locking block 310 is set as an inclined surface, and the side of the fixing block 304 is set as an inclined surface. The displacement of the fixing block 304 and the locking block 310 can be controlled by pulling the support rod 302 or the disc 309, so as to realize the quick disassembly or replacement of the curling knife 103.

[0041] In this embodiment, pulling the support rod 302 causes the mounting plate 301 to move, and the movement of the support rod 302 causes the fixing block 304 to move. When the fixing block 304 moves to the side of the locking block 310, the fixing block 304 will press against the inclined surface of the locking block 310, causing the locking block 310 to move. The return spring 308 on the side of the locking block 310 is compressed. When the fixing block 304 moves to the side of the locking block 310, the fixing rod 307 drives the locking block 310 to move. The spring force of the reset spring 308 resets the plate 310, which then locks the fixing block 304, thereby fixing the mounting plate 301. The mounting plate 301 fixes the curling blade 103. When the curling blade 103 needs to be disassembled or replaced, the disc 309 is pulled to move the fixing rod 307 and the locking block 310. At this time, the fixing block 304 loses its limit and is reset by the spring force of the spring 303. The mounting plate 301 is then moved away from the curling blade 103, and the curling blade 103 can be disassembled.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
