Description

Technical Field

[0001] The utility model relates to the technical field of fabric cutting, in particular to a fabric cutting device. Background Technique

[0002] An inflatable air model, as a decoration or advertising prop that expands and forms by inflation, cutting the fabric during its production process is a crucial step.

[0003] A Chinese patent with the publication number CN117248365A discloses a fabric cutting device, which includes: a conveying table installed on a processing table, and a first reel and a second reel are respectively rotatably installed at both ends of the processing table through connecting frames; a hot wire cutter is installed on the control frame; mounting frames slidably connected to both sides of the processing table, and a first clamping assembly and a second clamping assembly are respectively installed on both sides of the upper end of each mounting frame. Both the first clamping assembly and the second clamping assembly include a bottom plate fixed to the mounting frame and a clamping plate rotatable with the mounting frame on one side of the bottom plate; when the mounting frame moves towards the first reel and the second reel, at this time, the ends of the printing paper and the adsorption film are placed between the bottom plate and the clamping plate. When the clamping plate swings towards the bottom plate to clamp the printing paper and the adsorption film, and drives its movement through the movement of the mounting frame and lays it above the fabric, the printing paper and the adsorption film can be quickly laid on the fabric, improving the efficiency.

[0004] When the existing fabric cutting device is in use, only by simple pressing and fixing, it is often difficult to ensure that the fabric always remains taut during the cutting process, and it is easy for the fabric to become loose or wrinkled. If the fabric becomes loose or wrinkled during the cutting process, it will cause the cutting line to deviate from the preset trajectory, resulting in cutting errors and affecting the cutting accuracy. Moreover, when the loose or wrinkled fabric is cut, the edges are prone to be rough and uneven, reducing the overall quality and aesthetics of the product; therefore, a fabric cutting device is proposed for the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve the problems raised in the above background technique, the utility model proposes a fabric cutting device.

[0006] The technical solution adopted by the present utility model to solve its technical problems is as follows: A fabric cutting device of the present utility model includes a support base. Both sides of the top of the support base are provided with sliding grooves. Moving plates are arranged in both sliding grooves. Support blocks are fixedly connected to the side walls of the two moving plates. Second pneumatic cylinders are installed on the two support blocks. The acting ends of the second pneumatic cylinders are equipped with second pneumatic rods. The bottom ends of the two second pneumatic rods are fixedly connected with fixed rods. A first swing rod and a second swing rod are sleeved on each fixed rod, and the first swing rod is arranged outside the second swing rod. A first tensioning wheel is rotatably installed by the cooperation of the two first swing rods, and a second tensioning wheel is rotatably installed by the cooperation of the two second swing rods. Two fixing frames are fixedly connected by the cooperation of the two fixed rods. Springs are fixedly connected between each first swing rod and second swing rod and the side wall of the corresponding fixing frame. After the two ends of the fabric are pressed and fixed, through the operation of the second pneumatic cylinder, the second pneumatic rod drives the fixed rod to move downward, and then the first tensioning wheel and the second tensioning wheel move downward accordingly. When the first tensioning wheel and the second tensioning wheel move downward to contact the fabric, with the continuous downward movement, the first tensioning wheel and the second tensioning wheel will pull the fabric to both sides, keeping the fabric in a taut state. The two ends of the fabric are pressed and fixed by the pressing wheels, and then the fabric is pulled to both sides by the first tensioning wheel and the second tensioning wheel to a taut state. This pressing and fixing and tensioning mechanism ensures the stability and flatness of the fabric during the cutting process, thereby greatly improving the cutting accuracy. When the fabric is in a taut state, its surface is more flat, effectively avoiding cutting errors caused by fabric wrinkles or slack. This flatness ensures the clarity and accuracy of the cutting line, improving the overall quality of the product. At the same time, when the taut fabric is cut, its edge is neater, reducing the phenomenon of roughness and unevenness, which not only improves the aesthetic appearance of the product.

[0007] Preferably, a first motor is installed on a moving plate. The output end of the first motor is connected to a first lead screw, and the other end of the first lead screw is rotatably installed on another moving plate. An L-shaped movable block is sleeved on the first lead screw. Two guide rods are fixedly connected between the two moving plates, and the guide rods penetrate through the L-shaped movable block. A first pneumatic cylinder is installed on the L-shaped movable block. The acting end of the first pneumatic cylinder is equipped with a first pneumatic rod, and a cutting knife is installed at the bottom end of the first pneumatic rod. Second lead screws are rotatably installed in both chutes, and the second lead screws penetrate through the moving plates. Two second motors are installed on the side wall of the support seat. The output end of the second motor is connected to one end of the second lead screw. After the fabric is pressed and fixed, when cutting the fabric, start the first pneumatic cylinder to make the first pneumatic rod drive the cutting knife to move vertically downward until the cutting knife moves down to contact the surface of the fabric. Then start the first motor to make the first lead screw rotate. With the cooperation of the guide rod, make the L-shaped movable block drive the cutting knife to move stably longitudinally. Start the second motor to make the second lead screw rotate. With the cooperation of the chute, make the moving plate drive the cutting knife to move stably horizontally, so as to be able to perform all-round cutting operations on the fabric.

[0008] Preferably, support frames are fixedly connected to both ends of the support seat. Screw holes are formed in both support frames. Threaded rods are rotatably assembled in both screw holes. Rotating caps are fixedly connected to the top ends of both threaded rods. Mounting frames are rotatably installed at the bottom ends of both threaded rods. Pressing wheels are rotatably installed in both mounting frames. Two rod holes are formed in each support frame. Limiting rods are inserted into each rod hole, and the bottom end of the limiting rod is fixedly connected to the top side wall of the mounting frame. Before cutting the fabric, first pull the fabric on the reel, pull its free end to the lower side of the pressing wheel far from the reel, and then rotate the rotating cap. With the cooperation of the limiting rod, make the threaded rod drive the pressing wheel to move vertically downward, so as to be able to press and fix both ends of the fabric and avoid the phenomenon of the fabric slipping in position during the cutting process.

[0009] Preferably, two bent plates are fixedly connected to one side wall of the support seat. Slots are formed at the top ends of both bent plates. When using this device, by setting the slots, it is convenient to disassemble and replace the reel.

[0010] The beneficial effects of the present utility model are as follows:

[0011] After the two ends of the fabric are pressed and fixed, the second pneumatic cylinder operates, and the fixed rod drives the first tensioning wheel and the second tensioning wheel to move downward. When the first tensioning wheel and the second tensioning wheel move downward until they come into contact with the fabric, as the downward movement continues, the first tensioning wheel and the second tensioning wheel will pull the fabric to both sides, keeping the fabric in a taut state. The two ends of the fabric are pressed and fixed by the pressing wheels, and then the first tensioning wheel and the second tensioning wheel are used to pull the fabric to both sides until it is in a taut state. This pressing and fixing and tensioning mechanism ensures the stability and flatness of the fabric during the cutting process, thereby greatly improving the cutting accuracy. When the fabric is in a taut state, its surface is flatter, effectively avoiding cutting errors caused by fabric wrinkles or slack. This flatness ensures the clarity and accuracy of the cutting lines, improving the overall quality of the product. At the same time, when the taut fabric is cut, its edges are neater, reducing the roughness and unevenness. This not only improves the aesthetics of the product. Description of the Drawings

When the first tensioning wheel 17 and the second tensioning wheel 18 move downward to contact the fabric, as the downward movement continues, the first tensioning wheel 17 and the second tensioning wheel 18 will pull the fabric to both sides, keeping the fabric in a taut state. The two ends of the fabric are pressed and fixed by the pressing wheels 27, and then the fabric is pulled to both sides by the first tensioning wheel 17 and the second tensioning wheel 18 until it is in a taut state. This pressing and fixing and tensioning mechanism ensures the stability and flatness of the fabric during the cutting process, thus greatly improving the cutting accuracy. When the fabric is in a taut state, its surface is smoother, effectively avoiding cutting errors caused by fabric wrinkles or slack. This flatness ensures the clarity and accuracy of the cutting lines and improves the overall quality of the product. At the same time, when the taut fabric is cut, its edges are neater, reducing the phenomenon of roughness and unevenness, which not only improves the aesthetic appearance of the product.

Two second motors 22 are installed on the side wall of the support base 1, and the output end of the second motor 22 is connected to one end of the second lead screw 21. After the fabric is pressed and fixed, when cutting the fabric, start the first pneumatic cylinder 8 to make the first pneumatic rod 9 drive the cutting knife 10 to move vertically downward until the cutting knife 10 moves down to contact the surface of the fabric, then start the first motor 4 to make the first lead screw 5 rotate.

[0022] Please refer to Figures 4-5 As shown, both ends of the support base 1 are fixedly connected with support frames 23. Screw holes are opened in both of the two support frames 23. Threaded rods 24 are rotatably assembled in both of the two screw holes. Rotating caps 25 are fixedly connected to the tops of the two threaded rods 24.

With the cooperation of the limit rod 28, make the threaded rod 24 drive the pressing wheel 27 to move vertically downward, so as to be able to press and fix both ends of the fabric and avoid the phenomenon that the position of the fabric slips during the cutting process.

[0023] Two bending plates 29 are fixedly connected to one side wall of the support base 1. Slots 30 are opened at the tops of the two bending plates 29. When using this device, by providing the slots 30, it is convenient to disassemble and replace the reel.

[0024] Working principle: When the existing fabric cutting device is in use, it is often difficult to ensure that the fabric always remains taut during the cutting process only by simple pressing and fixing. This can easily cause the fabric to become loose or wrinkled. If the fabric becomes loose or wrinkled during the cutting process, it will cause the cutting line to deviate from the preset trajectory, resulting in cutting errors and affecting the cutting accuracy. Moreover, when cutting loose or wrinkled fabric, the edges are prone to being rough and uneven, reducing the overall quality and aesthetics of the product. Therefore, a fabric cutting device is proposed to address the above problems. Before cutting the fabric, first pull the fabric on the reel, and pull its free end to the lower side of the pressing wheel 27 away from the reel. Then rotate the rotating cap 25. With the cooperation of the limiting rod 28, the threaded rod 24 drives the pressing wheel 27 to move vertically downward, so as to be able to press and fix both ends of the fabric, avoiding the phenomenon of the fabric slipping in position during the cutting process. After both ends of the fabric are pressed and fixed, the second pneumatic cylinder 12 operates, causing the second pneumatic rod 13 to drive the fixed rod 14 to move downward, and then the first tensioning wheel 17 and the second tensioning wheel 18 move downward accordingly. When the first tensioning wheel 17 and the second tensioning wheel 18 move downward to contact the fabric, as the downward movement continues, the first tensioning wheel 17 and the second tensioning wheel 18 will pull the fabric to both sides, keeping the fabric in a taut state. By pressing and fixing both ends of the fabric with the pressing wheel 27 and then using the first tensioning wheel 17 and the second tensioning wheel 18 to pull the fabric to both sides to a taut state, this pressing and fixing and tensioning mechanism ensures the stability and flatness of the fabric during the cutting process, thus greatly improving the cutting accuracy. When the fabric is in a taut state, its surface is smoother, effectively avoiding cutting errors caused by fabric wrinkles or looseness. This flatness ensures the clarity and accuracy of the cutting lines and improves the overall quality of the product. At the same time, when cutting the taut fabric, its edges are neater, reducing the rough and uneven phenomenon, which not only improves the aesthetics of the product;

[0025] After the fabric is pressed and fixed and in a taut state, when cutting the fabric, start the first pneumatic cylinder 8, so that the first pneumatic rod 9 drives the cutting knife 10 to move vertically downward until the cutting knife 10 moves downward to contact the surface of the fabric. Then start the first motor 4, so that the first lead screw 5 rotates. With the cooperation of the guide rod 7, the L-shaped movable block 6 drives the cutting knife 10 to move stably longitudinally. Start the second motor 22, so that the second lead screw 21 rotates. With the cooperation of the chute 2, the moving plate 3 drives the cutting knife 10 to move stably horizontally, so as to be able to perform a full-range cutting operation on the fabric.
