Description

Technical Field

[0001] The utility model relates to the technical field of shearing devices, in particular to a shearing device for reducing the generation of fiber fluff. Background Technique

[0002] Fabric is a material woven from various fibers or yarns, with diverse types, structures, and textures. It can be used to make clothing, furniture, home decorations, etc. According to its material, weaving method, structure, and color characteristics, choosing a suitable fabric can meet different needs and provide a rich variety of choices.

[0003] When processing fabric, a shearing device is required. However, when the existing shearing device shears the fabric, since the fabric cannot be well fixed, the fabric is prone to move under force during the shearing process, resulting in unsmooth cutting, and then the generation of frayed edges and the dropping of fiber fluff, which affects the quality of the fabric. Moreover, the dropped fiber fluff will adhere to the surface or nearby of the fabric, increasing the difficulty of cleaning and maintenance. Content of the Utility Model

[0004] The purpose of the utility model is to provide a shearing device for reducing fiber fluff, which can improve the shearing quality and reduce the generation of frayed edges and fiber fluff.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows.

[0006] A shearing device for reducing fiber fluff includes a bottom plate. A notch is provided on the surface of the bottom plate along its width direction. A U-shaped frame is installed on the upper surface of the bottom plate. An electric push rod is installed at the top of the U-shaped frame. The end of the telescopic end of the electric push rod penetrates to the inner side of the U-shaped frame and is installed with a lifting plate. A collection box is installed at the bottom of the lifting plate through a moving mechanism. A blade is provided at the bottom of the collection box. A suction pipe is connected to the outer surface of the collection box, and the end of the suction pipe is arranged on the side of the blade. A suction mechanism is arranged inside the collection box. Two pressing plates are arranged on the lower side of the lifting plate. The gap between the two pressing plates corresponds to the notch. Guide rods are connected to both sides of the upper surface of the pressing plate. The ends of the guide rods penetrate to the upper side of the lifting plate. A top plate is installed at the top of the guide rods. A first spring is sleeved on the outer surface of the guide rods, and both ends of the first spring are abutted against the pressing plate and the lifting plate respectively.

[0007] It can be seen that through the setting of the pressing plate, when the electric push rod drives the blade to descend, the cloth can be tightly fixed on both sides of the incision, thereby reducing the situation that the cloth moves during shearing and causing burrs, improving the shearing quality. Through the setting of the suction mechanism, during the shearing process, the generated fiber hairs can be sucked away through the suction pipe, thereby reducing the situation that the fiber hairs adhere to the surface or near the cloth, reducing the difficulty of cleaning and maintenance. Through the setting of the moving mechanism, the blade can be driven to move along the length direction of the incision to realize the shearing of the cloth. A collection box is installed at the bottom of the lifting plate through the moving mechanism, and the blade is arranged at the bottom of the collection box. The collection box itself serves as the support structure of the blade, simplifying the structure, saving space and manufacturing cost.

[0008] Furthermore, the moving mechanism includes a housing installed on the lower surface of the lifting plate. A motor is installed on one side of the inner wall of the housing. The end of the output shaft of the motor is connected to a threaded rod, and the end of the threaded rod is rotatably connected to the inner wall of the other side of the housing. A nut seat is installed on the outer surface of the threaded rod, a connecting block is installed on the outer surface of the nut seat, and the end of the connecting block is connected to the collection box.

[0009] When the electric push rod drives the blade to descend and cut the edge of the cloth, the motor can be started to drive the threaded rod to rotate, and then the nut seat can be driven to move along the length direction of the threaded rod, and the blade can be driven by the collection box to complete the shearing of the cloth.

[0010] Furthermore, the suction mechanism includes an installation pipe installed on the side of the collection box facing away from the suction pipe. A fan is installed inside the installation pipe. A filter screen is installed at the end of the installation pipe located inside the collection box. A drawer is arranged inside the collection box, and the drawer is arranged below the filter screen.

[0011] During the shearing process, by starting the fan, a negative pressure can be generated inside the collection box, and suction can be generated at the end of the suction pipe. The fiber hairs generated during the shearing process of the blade can be sucked away by the suction pipe and enter the collection box. Due to the setting of the filter screen, the fiber hairs can be filtered, and the limiting hairs can fall on the drawer for easy cleaning. Moreover, the collection box moves with the movement of the blade, which can ensure that the fiber hairs at the shearing position are always sucked at a close distance, and the use effect is good.

[0012] Furthermore, a first installation block is installed at the bottom of the collection box, a second installation block is installed at the top of the blade. A connection groove is formed on the lower surface of the first installation block. A connection block is installed at the top of the second installation block. The connection block is adapted to the connection groove. An inner groove is formed inside the connection block. A positioning block is arranged inside the inner groove. A positioning groove is formed on the outer surface of the first installation block, and the positioning block is adapted to the positioning groove. Two second springs are arranged inside the inner groove, and the two ends of the second springs are respectively abutted against the positioning block and the inner wall of the inner groove.

[0013] As a consumable part subject to wear, when the blade needs to be replaced, the positioning block can be pressed inward to make it enter the connecting groove, and then the second mounting block can be separated from the first mounting block to complete the removal of the blade. When installing the blade, the positioning block can be first pressed to the inner side of the connecting block. At this time, the positioning block will compress the second spring, and then the connecting block is inserted into the connecting groove. When the positioning block aligns with the positioning groove, the compressed second spring can push the positioning block to move outward and extend from the positioning groove, thus completing the rapid replacement of the blade, which is more convenient to use, reduces the downtime caused by blade replacement, and improves production efficiency.

[0014] Further, two first limiting rods are installed inside the inner groove, and the positioning block is slidably installed on the two first limiting rods, and the second spring is sleeved on the outer surface of the first limiting rod.

[0015] Through the setting of the first limiting rod, the second spring can be limited and guided to prevent it from bending and deforming, and improve its service performance and quality.

[0016] Further, both sides of the upper surface of the lifting plate are connected with second limiting rods, and the ends of the second limiting rods penetrate to the upper side of the U-shaped frame.

[0017] Through the setting of the second limiting rod, the lifting plate can be limited and guided to improve the stability of the lifting plate during lifting. Description of the Drawings

Specific embodiments

[0024] The present utility model will be described in detail below with reference to the accompanying drawings.

[0025] As Figures 1-5 shown, a shearing device for reducing fiber hairs includes a bottom plate 100. An incision 101 is formed on the surface of the bottom plate 100 along its width direction. A U-shaped frame 102 is installed on the upper surface of the bottom plate 100. An electric push rod 103 is installed at the top of the U-shaped frame 102. The end of the telescopic end of the electric push rod 103 penetrates to the inside of the U-shaped frame 102 and is installed with a lifting plate 104. The bottom of the lifting plate 104 is installed with a collection box 105 through a moving mechanism 200. A blade 106 is arranged at the bottom of the collection box 105. A suction tube 107 is connected to the outer surface of the collection box 105, and the end of the suction tube 107 is arranged on the side of the blade 106. A suction mechanism 300 is arranged inside the collection box 105. Two pressing plates 108 are arranged on the lower side of the lifting plate 104. The gap between the two pressing plates 108 corresponds to the incision 101. Both sides of the upper surface of the pressing plate 108 are connected with guide rods 109. The ends of the guide rods 109 penetrate to the upper side of the lifting plate 104. The tops of the guide rods 109 are installed with a top plate 110. A first spring 111 is sleeved on the outer surface of the guide rod 109. The two ends of the first spring 111 are respectively abutted against the pressing plate 108 and the lifting plate 104.

[0026] During use, first lay the fabric flat on the bottom plate 100, then start the electric push rod 103. The electric push rod 103 drives the lifting plate 104 and the pressing plate 108 to descend. When the pressing plate 108 first contacts the fabric, as the lifting plate 104 continues to descend, the first spring 111 can be compressed. Through the elastic force of the first spring 111, the pressing plate 108 can be pushed to press tightly on the fabric. As the lifting plate 104 drives the blade 106 to descend, the edge of the fabric can be cut. Subsequently, the moving mechanism 200 drives the blade 106 to move horizontally, thereby completing the shearing of the fabric, reducing the occurrence of frayed edges, improving product quality. And during the shearing process, through the setting of the suction mechanism 300, suction can be generated at the end of the suction pipe 107, and thus the generated fiber hairs can be sucked away, reducing the situation where fiber hairs adhere to the surface or near the fabric, and reducing the difficulty of cleaning and maintenance.

[0027] Specifically, the moving mechanism 200 includes a housing 201 installed on the lower surface of the lifting plate 104. One side of the inner wall of the housing 201 is installed with a motor 202. The end of the output shaft of the motor 202 is connected with a threaded rod 203, and the end of the threaded rod 203 is rotatably connected to the inner wall of the other side of the housing 201. A nut seat 204 is installed on the outer surface of the threaded rod 203. A connecting block 205 is installed on the outer surface of the nut seat 204. The end of the connecting block 205 is connected with the collection box 105. When the electric push rod 103 drives the blade 106 to descend and cut the edge of the fabric, the motor 202 can be started to drive the threaded rod 203 to rotate, thereby driving the nut seat 204 to move along the length direction of the threaded rod 203, and driving the blade 106 to complete the shearing of the fabric through the collection box 105.

[0028] Specifically, the suction mechanism 300 includes a mounting pipe 301 installed on the side of the collection box 105 facing away from the suction pipe 107. A fan 302 is installed inside the mounting pipe 301. A filter screen 303 is installed at the end of the mounting pipe 301 located inside the collection box 105. A drawer 304 is arranged inside the collection box 105, and the drawer 304 is arranged below the filter screen 303. During the shearing process, by starting the fan 302, negative pressure can be generated inside the collection box 105, and suction can be generated at the end of the suction pipe 107. The fiber hairs generated during the shearing process by the blade 106 can be sucked away by the suction pipe 107 and enter the collection box 105. And due to the setting of the filter screen 303, the fiber hairs can be filtered, and the limiting hairs can fall on the drawer 304, facilitating cleaning. And the collection box 105 moves along with the movement of the blade 106, which can ensure that the fiber hairs at the shearing position are always sucked at a close distance, and the use effect is good.

[0029] Specifically, a first mounting block 400 is installed at the bottom of the collection box 105, and a second mounting block 401 is installed at the top of the blade 106. A connecting groove 402 is formed on the lower surface of the first mounting block 400. A connecting block 403 is installed at the top of the second mounting block 401. The connecting block 403 is adapted to the connecting groove 402. An inner groove 404 is formed inside the connecting block 403. A positioning block 405 is arranged inside the inner groove 404. A positioning groove 406 is formed on the outer surface of the first mounting block 400, and the positioning block 405 is adapted to the positioning groove 406. Two second springs 407 are arranged inside the inner groove 404, and the two ends of the second spring 407 are respectively abutted against the positioning block 405 and the inner wall of the inner groove 404. The blade 106 is a consumable material. When it needs to be replaced, the positioning block 405 can be pressed inward to make it enter the connecting groove 402, and then the second mounting block 401 can be separated from the first mounting block 400 to complete the removal of the blade 106. When installing the blade 106, the positioning block 405 can be first pressed to the inside of the connecting block 403. At this time, the positioning block 405 will compress the second spring 407. Then the connecting block 403 is inserted into the connecting groove 402. When the positioning block 405 is aligned with the positioning groove 406, the compressed second spring 407 can push the positioning block 405 to move outward and extend from the positioning groove 406, so as to complete the rapid replacement of the blade 106, which is more convenient to use, reduces the downtime caused by replacing the blade 106, and improves the production efficiency.

[0030] Specifically, two first limiting rods 500 are installed inside the inner groove 404, and the positioning block 405 is slidably installed on the two first limiting rods 500, and the second spring 407 is sleeved on the outer surface of the first limiting rod 500. Through the arrangement of the first limiting rod 500, the second spring 407 can be limited and guided to prevent it from bending and deforming, and improve its service performance and quality.

[0031] Specifically, both sides of the upper surface of the lifting plate 104 are connected with second limiting rods 600. The ends of the second limiting rods 600 penetrate to the upper side of the U-shaped frame 102. Through the arrangement of the second limiting rods 600, the lifting plate 104 can be limited and guided to improve the stability of the lifting plate 104 during lifting.

It cannot be determined that the specific embodiments of the present invention are only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several equivalent substitutions or obvious modifications are made, and the performance or use is the same, and all should be regarded as belonging to the patent protection scope determined by the claims submitted by the present invention.
