[0001] This utility model belongs to the technical field of fabric feeding devices, and in particular, a fabric feeding device for laser cutting beds. Background Technology

[0002] With the advancement of technology and the continuous development of society, production and processing equipment has been continuously improved and optimized, making production and processing simpler and more convenient. The continuous optimization and improvement of the fabric feeding device for laser cutting tables has reduced production costs, reduced labor expenditures, and promoted the faster development of factories and enterprises. Therefore, it can be seen that the current fabric feeding device for laser cutting tables basically meets people's needs, but some problems still exist.

[0003] Most existing fabric feeding devices for laser cutting beds use traction rollers to directly transport the fabric to the laser cutting area of ​​the laser cutting bed. However, the fabric is particularly soft, so wrinkles may occur after the fabric is transported to the laser cutting area, which directly affects the laser cutting effect. Therefore, a new fabric feeding device for laser cutting beds is needed to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a fabric feeding device for a laser cutting bed to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fabric feeding device for a laser cutting bed, comprising a mounting frame for mounting the laser cutting bed and a laser cutting device for the laser cutting bed, wherein a U-shaped frame is mounted on the top surface of the mounting frame, and the laser cutting device is installed through the side wall of the U-shaped frame.

[0006] Fabric-laying wheels are rotatably mounted between the vertical inner walls of the upper half of the mounting frame;

[0007] The mounting frame has two symmetrical strip grooves on opposite side walls. The two strip grooves are arranged horizontally, and a slider is slidably installed on the inner wall of the strip groove. A tension roller is fixedly and rotatably installed between the two sliders, and a push spring is fixedly installed on the inner wall of the strip groove, with the end of the push spring fixedly connected to the slider.

[0008] Guide rollers are rotatably mounted between the vertical inner walls of the lower half of the mounting frame;

[0009] The lower interior of the mounting frame is symmetrically provided with mounting grooves, and a conveyor belt is rotatably mounted inside the mounting grooves. The inner wall of the mounting frame is symmetrically rotatably mounted with drive rollers, and the outer walls of the two drive rollers are rotatably sleeved with conveyor belts.

[0010] Preferably, two limiting grooves are symmetrically formed on the inner walls of the two strip grooves, and two limiting blocks are symmetrically fixedly installed on the side walls of the slider.

[0011] Preferably, the two limiting blocks fixedly installed on the side wall of the slider are slidably connected to the inside of the two limiting grooves opened on the inner wall of the strip groove.

[0012] Preferably, guide rods are fixedly installed laterally on the inner walls of the two strip grooves, and limit holes are opened laterally through the side wall of the slider.

[0013] Preferably, the guide rods provided on the inner wall of the strip groove slide through the limiting holes provided on the side wall of the slider.

[0014] Preferably, a plurality of pressure rollers are rotatably mounted on the inner wall of the mounting frame, and the plurality of pressure rollers all roll and extend into the interior of the second conveyor belt and roll and adhere to the inner wall of the second conveyor belt.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] The fabric feeding device for this laser cutting bed, thanks to the arrangement of the fabric feeding roller, tension roller, and guide roller, allows the fabric to be wound around the side wall of the tension roller via the fabric feeding roller, and then wound around to the bottom of the guide roller. The fabric feeding roller, tension roller, and guide roller are arranged in a triangle, which can tension the fabric and make it flatter. The guide roller is close to the lower inner end of the mounting frame, which can guide the fabric to the lower inner end of the mounting frame, thus facilitating the delivery of the fabric to the lower inner end of the mounting frame and cutting it by the laser fabric cutting device.

[0017] The fabric feeding device for this laser cutting bed benefits from the design of the strip groove, slider, and push spring, and the tension roller is rotatably installed between the two sliders. In this way, the push spring pushes the slider and the tension roller to push the fabric, thereby further improving the tension of the fabric.

[0018] The fabric feeding device for this laser cutting bed, thanks to the arrangement of conveyor belt one, conveyor belt two, and drive rollers, pulls the fabric between conveyor belt one and conveyor belt two. The conveyor belt one and conveyor belt two are slidably attached, which can clamp the two sides of the fabric and transport it to the bottom of the laser cutting device. This can flatten the fabric before transporting it to the bottom of the laser cutting device, thus preventing the fabric from wrinkling and affecting the cutting effect of the laser cutting device.

[0019] Compared with existing technologies, the fabric feeding device for this laser cutting bed can effectively flatten the fabric used in the laser cutting bed, thereby preventing wrinkles from affecting the laser cutting effect. Attached Figure Description

[0027] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0028] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0029] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0030] like Figures 1 to 4The main structure of the fabric feeding device for a laser cutting bed shown is a mounting frame 1 for installing the laser cutting bed and a laser cutting device 2 for the laser cutting bed. A U-shaped frame 3 is mounted on the top surface of the mounting frame 1, and the laser cutting device 2 is installed through the side wall of the U-shaped frame 3. A fabric feeding wheel 4 is rotatably mounted between the vertical inner walls of the upper half of the mounting frame 1, and a guide roller 8 is rotatably mounted between the vertical inner walls of the lower half of the mounting frame 1. The fabric feeding wheel 4, the tension roller 7, and the guide roller 8 are arranged in a triangular configuration, which can tension the fabric and make it flatter.

[0031] The mounting frame 1 has two symmetrical strip grooves 5 on opposite side walls. The two strip grooves 5 are arranged horizontally, and a slider 6 is slidably installed on the inner wall of the strip groove 5. A tension roller 7 is fixedly and rotatably installed between the two sliders 6. A push spring 16 is fixedly installed on the inner wall of the strip groove 5, and the end of the push spring 16 is fixedly connected to the slider 6. The two push springs 16 push the slider 6 fixedly installed at its end to slide along the inside of the strip groove 5, thereby driving the tension roller 7 rotatably installed between the two sliders 6 to move along the strip groove 5. This can effectively push the fabric outside the tension roller 7, thereby tensioning the fabric and preventing the fabric from becoming loose and wrinkled.

[0032] The lower interior of the mounting frame 1 is symmetrically provided with mounting grooves 9, and a first conveyor belt 10 is rotatably mounted inside the mounting grooves 9. A drive roller 12 is symmetrically rotatably mounted on the inner wall of the mounting frame 1, and a second conveyor belt 11 is rotatably sleeved on the outer wall of the two drive rollers 12. Thanks to the structure of the first conveyor belt 10, the second conveyor belt 11 and the drive roller 12, the fabric is pulled between the first conveyor belt 10 and the second conveyor belt 11. The first conveyor belt 10 and the second conveyor belt 11 are slidably attached, so that the two sides of the fabric can be clamped and transported to the bottom of the laser fabric cutting device 2. This can flatten the fabric before transporting it to the bottom of the laser fabric cutting device 2, thus preventing the fabric from wrinkling and affecting the cutting effect of the laser fabric cutting device 2.

[0033] Two limiting grooves are symmetrically opened on the inner walls of the two strip grooves 5, and two limiting blocks 13 are symmetrically fixedly installed on the side walls of the slider 6. The two limiting blocks 13 fixedly installed on the side walls of the slider 6 are slidably connected to the inside of the two limiting grooves opened on the inner walls of the strip grooves 5. The two limiting blocks 13 can effectively limit the sliding direction of the slider 6, and further improve the stability of the slider 6 when sliding.

[0034] Guide rods 14 are fixedly installed laterally on the inner walls of the two strip grooves 5. Limiting holes are opened laterally through the side wall of the slider 6. The guide rods 14 opened on the inner wall of the strip groove 5 slide through the limiting holes opened on the side wall of the slider 6 respectively. The guide rods 14 are slidably sleeved inside the push spring 16. This can effectively improve the stability of the two sliders 6 and the tension roller 7 when sliding, and can prevent the push spring 16 from deforming when it extends and retracts.

[0035] Multiple pressure rollers 15 are rotatably mounted on the inner wall of the mounting frame 1, and all multiple pressure rollers 15 roll and extend into the interior of the second conveyor belt 11 and roll and adhere to the inner wall of the second conveyor belt 11. The multiple pressure rollers 15 can effectively improve the tighter adhesion between the first conveyor belt 10 and the second conveyor belt 11, thereby further improving the clamping effect on the fabric.

[0036] Working principle

[0037] In use, the fabric feeding device for this laser cutting bed first winds the fabric around the outside of the tension roller 7 via the fabric feeding wheel 4, then winds the fabric around the bottom of the guide roller 8, and then pulls the fabric between the two sets of conveyor belts 10 and 11. The fabric is fed by the drive roller 12. At the same time, the push spring 16 installed on the inner wall of the strip groove 5 opened in the inner wall of the mounting frame 1 pushes the slider 6 to move, which synchronously drives the tension roller 7 between the sliders 6 to move. This can effectively tension the fabric outside the tension roller 7, thereby preventing the fabric from becoming loose and wrinkled.
