Description

Technical Field

[0001] This utility model relates to the field of textile material processing technology, specifically to a new material cutting device for textiles. Background Technology The existing equipment requires the use of shearing blades during shearing. As the blades gradually wear down during use, the shearing effect and quality are affected. Therefore, the blades need to be inspected or replaced regularly. Since the blades of the existing equipment are generally fixed with multiple screws, when replacing them, the screws must be removed first before the blade can be taken out. Then, the new blade is taken out and the multiple screws are tightened in sequence. The whole replacement process is cumbersome and wastes a lot of time. CN222455640U discloses a new material cutting device for textiles, including a base plate with a through groove in the middle. A connecting plate is fixedly installed at the telescopic end of a hydraulic rod, and a blade is fixedly installed at the bottom of the mounting plate. The limiting component includes a groove inside the connecting plate and located on one side of the mounting groove. Two springs are fixedly installed on the side of the groove away from the mounting groove, and a locking block is fixedly installed at the other end of the two springs, with the locking block slidably connected to the spring. An inner hole is opened on each opposite side of the mounting plate, and the locking block engages with the inner hole. By setting a replaceable shearing blade, when the blade wears down after long-term use, affecting the shearing effect and quality, the blade can be quickly replaced. The entire replacement process is more convenient and faster, reducing the time required for workers to replace the blade and improving the shearing efficiency of the equipment. However, this patent still has the following problems in actual use: The above-mentioned device is similar to most quick-release structures, and it is installed by plugging in. However, due to the low manufacturing precision of the slots in such devices, and considering the cost, it is difficult to improve the precision. As a result, there will inevitably be gaps in the traditional plugging. When the blade is inserted into the slot, there is no fastening structure. This gap will cause the blade to collide with the blade holder due to inertia when it is raised and lowered. This will not only cause more noise, but the impact will also damage the blade itself, reduce its stability, and affect its service life.

[0002] A novel cutting device for textile materials is proposed to address the problems mentioned above. Utility Model Content

[0003] The purpose of this utility model is to provide a new material cutting device for textiles, in order to solve the problem that the aforementioned device is similar to most quick-release structures, which are installed by plugging in. However, due to the low precision of the slots in such devices, and considering the cost, it is difficult to improve the precision. As a result, there will inevitably be gaps in the traditional plugging. When the blade is inserted into the slot, there is no fastening structure. This gap will cause the blade to collide with the blade holder due to inertia when it is raised and lowered. This will not only cause a lot of noise, but the impact will also damage the blade itself, reduce its stability, and affect its service life.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a new material cutting device for textiles, comprising a processing box, wherein a top cover is threadedly installed on the top of the processing box; The processing box is equipped with a cutting assembly, which includes a telescopic air rod fixedly installed inside the processing box. A top plate is fixedly connected to the top of the telescopic air rod. A tool holder clip is snapped into one side of the top plate. A rubber gasket is fixedly connected to the outer side of the tool holder clip. An extrusion plate is attached to the outer side of the rubber gasket. A shaft seat is fixedly installed on the outer side of the extrusion plate. A pair of bent rods are fixedly connected to the shaft of the shaft seat. A connecting rod is fixedly connected to the end of the bent rod away from the extrusion plate. The connecting rod is fixedly connected to an inclined block on its inner side, the top of the top plate is rotatably connected to a positioning shaft, and the positioning shaft is fixedly connected to a cam and a rocker arm on its outer side.

[0005] Preferably, guide strips are fixedly connected to both the top and bottom surfaces of the top plate, and inserts are symmetrically fixedly connected to the side of the top plate near the blade holder strip. Guide strips are symmetrically provided on the blade holder strip, rubber gasket, and extrusion plate, and the blade body is fixedly welded to the bottom of the blade holder strip.

[0006] Preferably, the insert post is inserted into the guide post, and the guide strip is inserted into the inner side of the rubber gasket.

[0007] Preferably, the inclined block has a groove in the middle, and the cam engages with the groove.

[0008] Preferably, the bottom of the top plate is provided with a pressing mechanism, the pressing mechanism includes a pair of lifting slide rods, the bottom end of the lifting slide rods is fixedly connected to a counterweight plate, the top of the lifting slide rods is threadedly connected to a threaded cap, and the bottom of the lifting slide rods is sleeved with a spring.

[0009] Preferably, the top end of the spring is fixedly connected to the top plate, and the bottom end of the spring is fixedly connected to the counterweight plate.

[0010] Preferably, the lifting slide rod slides through the top plate, and the top of the lifting slide rod is provided with external threads.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This new material cutting device for textiles uses a telescopic air rod to drive the top plate in conjunction with a pressing mechanism to ensure stable positioning during material cutting. Furthermore, the blade body is easily assembled and disassembled through the insertion of the blade holder strip into the top plate and the cooperation of multiple components, greatly improving the cutting accuracy, stability, and blade life. The specific details are as follows: 1. The tool holder retainer and top plate feature an interlocking design, along with a fastening system comprised of a compression plate, bending rod, connecting rod, bevel block, and cam, providing a reliable fixation for the blade body. During blade installation, the interlocking and fitting operation allows for quick and accurate blade positioning. During cutting, the engagement of the cam and bevel block, along with the compression deformation of the rubber gasket, effectively limits the retainer in both horizontal and vertical directions, significantly reducing gaps and minimizing blade wobble during operation, thus improving stability and tool life. Furthermore, this design facilitates blade removal and replacement; simply cranking the handle utilizes the rotation of the cam and the action of the compression plate, saving time and labor costs associated with traditional threaded blade replacement and improving production efficiency.

[0012] 2. During the cutting process, the counterweight plate can pre-press down the new textile material, effectively preventing the material from moving or misaligning during cutting, thus ensuring the precision and accuracy of the cut. As the top plate descends, the lifting slide rod slides relative to the top plate, and the spring deforms, further increasing the pressure of the counterweight plate on the material. This allows it to adapt to new textile materials of different thicknesses and textures, ensuring that the material remains stable throughout the cutting process. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-5 The present invention provides a technical solution: a new material cutting device for textiles, including a processing box 1, and a top cover 101 threadedly installed on the top of the processing box 1; The processing box 1 is equipped with a cutting assembly 2. The cutting assembly 2 includes a telescopic air rod 201 fixedly installed inside the processing box 1. A top plate 202 is fixedly connected to the top of the telescopic air rod 201. A tool holder clip 203 is fixedly connected to one side of the top plate 202. A rubber gasket 204 is fixedly connected to the outside of the tool holder clip 203. An extrusion plate 205 is attached to the outside of the rubber gasket 204. A shaft seat 206 is fixedly installed to the outside of the extrusion plate 205. A pair of bending rods 207 are fixedly connected to the shaft of the shaft seat 206. A connecting rod 208 is fixedly connected to the end of the bending rod 207 away from the extrusion plate 205. When the extrusion plate 205 is attached to the rubber gasket 204, the bending rods 207 are turned upside down and placed on the top plate 202 by moving the bending rods 207. The connecting rod 208 is fixedly connected to the inclined block 209 on its inner side, and the top plate 202 is rotatably connected to the positioning shaft 210. The positioning shaft 210 is fixedly connected to the outer side of the cam 211 and the rocker arm 212. When the rocker arm 212 is turned, the cam 211 rotates, and the protruding edge of the cam 211 slides along the outer side of the inclined block 209. During this process, the connecting rod 208 will pull the extrusion plate 205 to slide further and extrude the rubber pad 204 through the bending rod 207 and the bearing seat 206. Finally, the tool holder clip 203 can be clamped by the extrusion plate 205 and the top plate 202, and a fastening force is applied to it in the horizontal direction. At this time, the rubber pad 204 is in a state of extrusion deformation.

[0017] Guide strips 2021 are fixedly connected to both the top and bottom surfaces of the top plate 202. Inserted posts 2022 are symmetrically fixedly connected to the side of the top plate 202 near the cutter holder strip 203. Guide posts 2041 are symmetrically provided on both the cutter holder strip 203 and the rubber gasket 204. The blade body is fixedly welded to the bottom of the cutter holder strip 203. The cutter holder strip 203 is inserted into the inserted post 2022 through the guide post 2041, and the cutter holder strip 203 is inserted into the top plate 202. The guide strips 2021 are inserted into the cutter holder strip 203, so that the cutter holder strip 203 can fit into the top plate 202. Then, the guide post 2041 on the extrusion plate 205 is inserted into the inserted post 2022, so that the extrusion plate 205 fits against the rubber gasket 204.

[0018] The insertion post 2022 is inserted into the guide post 2041, and the guide strip 2021 is inserted into the inner side of the rubber gasket 204.

[0019] A groove 2091 is provided in the middle of the inclined block 209, and the cam 211 engages with the groove 2091. The cam 211 is engaged with the groove 2091 until the protrusion of the cam 211 is engaged with the groove 2091. Under the deformation elastic force of the rubber pad 204, a reaction force is applied to increase the stability of the cam 211 after engaging with the groove 2091. Finally, when the device is disassembling the blade body, it is only necessary to shake the crank 212 to make the positioning shaft 210 drive the cam 211 to rotate. When the blade holder strip 203 is limited in the vertical direction by the top plate 202 and the insert post 2022, the extrusion plate 205 applies pressure to it in the horizontal direction to further reinforce it. When the blade holder strip 203 is extruded, even if there is a gap between the blade holder strip 203 and the insert post 2022 or the guide strip 2021, the gap will be reduced due to the extrusion, thus reducing the shaking of the blade holder strip 203 during operation.

[0020] A pressing mechanism 3 is provided at the bottom of the top plate 202. The pressing mechanism 3 includes a pair of lifting slide rods 301. A counterweight plate 303 is fixedly connected to the bottom end of the lifting slide rod 301. A threaded cap 302 is threadedly connected to the top of the lifting slide rod 301. A spring 304 is sleeved at the bottom of the lifting slide rod 301. When the telescopic air rod 201 drives the top plate 202 to descend, the counterweight plate 303 will press the material in advance. As the top plate 202 continues to descend, the lifting slide rod 301 slides relative to the top plate 202, and the spring 304 deforms, increasing the pressure of the counterweight plate 303 on the material. Moreover, as the top plate 202 moves upward, the threaded cap 302 fits against the top surface of the top plate 202, and the threaded cap 302 can drive the lifting slide rod 301 to move vertically away from the material.

[0021] The top end of the spring 304 is fixedly connected to the top plate 202, and the bottom end of the spring 304 is fixedly connected to the counterweight plate 303.

[0022] The lifting slide rod 301 slides through the top plate 202, and the top of the lifting slide rod 301 is provided with external threads.

[0023] Working principle: Before using this new textile material cutting device, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5 As shown, when the telescopic air spring 201 is activated, it lowers the top plate 202. During the descent of the top plate 202, the counterweight plate 303 in the pressing mechanism 3 presses down on the material in advance. As the top plate 202 continues to descend, the lifting slide 301 slides relative to the top plate 202, and the spring 304 deforms, further increasing the pressure of the counterweight plate 303 on the material, ensuring the material's position is stable during cutting. When the top plate 202 reaches the appropriate position, the blade body is installed at the bottom of the blade holder 203 to cut the material. After cutting, the telescopic air spring 201 raises the top plate 202, the threaded cap 302 adheres to the top surface of the top plate 202, and the lifting slide 301 moves vertically, moving the counterweight plate 303 away from the material.

[0024] In terms of the installation and removal of the blade body, the blade holder clip 203 is inserted and fitted into the top plate 202, and then the clamping and loosening of the blade holder clip 203 is achieved by the cooperation of components such as the pressing plate 205, bending rod 207, connecting rod 208, inclined block 209 and cam 211, which facilitates the replacement of the blade body.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
