Description

Technical Field

[0001] The utility model relates to the technical field of textile processing, and specifically relates to a device for preventing deviation and trimming the edges of textiles during processing. Background Technique

[0002] Textiles are products woven from textile fibers and are divided into two major categories: shuttle-woven fabrics and knitted fabrics. China is one of the earliest countries in the world to produce textiles. When textiles are processed, a trimming machine is required for trimming. The trimming machine is mainly used in garment processing enterprises to cut textiles.

[0003] After retrieval, a trimming device for textile processing with the application number 202320387185.0 was found. This device can cut both sides of the textile simultaneously when simply trimming one side of the textile, eliminating the need for manual adjustment of the textile and then secondary trimming, thus shortening the cutting time. However, when the two side cutters of this device trim the textile, since only one side of the textile is fixed, during trimming, the cutter will press the fabric into the groove, resulting in the phenomenon of incomplete cutting. At the same time, the cutter is in a fixed position and cannot specify the required trimming distance, so the usage scenario is limited. Content of the Utility Model

[0004] Based on this, the purpose of the present utility model is to provide a device for preventing deviation and trimming the edges of textiles during processing to solve the technical problems in the above background technique.

[0005] To achieve the above purpose, the present utility model provides the following technical solution: A device for preventing deviation and trimming the edges of textiles during processing, including a base. A workbench is connected to the top of the base. Support frames are connected to both sides of the top of the workbench. A hydraulic cylinder is provided at the top of the support frame. The output end of the hydraulic cylinder is connected to a sliding frame. An adjustment component is arranged inside the sliding frame. The adjustment component includes a rotating rod. A gear and a worm gear are connected to the outside of the rotating rod. A worm is arranged on the back of the sliding frame. A rotating wheel is connected to the top of the worm. Guide frames are arranged on both sides inside the sliding frame. A slider is connected to the outside of the guide frame. A rack is connected to one side of the slider. A tool rest is connected to the bottom of the slider. A cutter is connected to the inner wall of the tool rest. Tensioning components are arranged on both sides of the tool rest. The tensioning components include a connecting block. A connecting rod and a tension spring are connected to the bottom of the connecting block. The lower end of the connecting rod is connected to a tensioning wheel. A turntable is connected to the middle of the top of the workbench through a rotating shaft. A grip rod is connected to the outer surface of the turntable. A limiting component is arranged below the inner part of the base. The limiting component includes a fixing plate. A traction rod is connected to the top of the fixing plate through a spring. A friction disc is arranged at the top of the traction rod. A pedal is connected to the bottom of the traction rod.

[0006] Furthermore, there are two groups of hydraulic cylinders, and the two groups of hydraulic cylinders are symmetrically distributed.

[0007] By adopting the above technical solution, when cutting textiles, the hydraulic cylinder is started, and the output end of the hydraulic cylinder drives the carriage to move downward, so that the cutting knife cuts both sides of the square textile on the turntable. Through symmetric arrangement, the carriage is evenly stressed, so that the two cutting knives are evenly stressed during cutting.

[0008] Furthermore, a chute is provided inside the support frame, and the chute is slidably connected to the carriage.

[0009] By adopting the above technical solution, driven by the output end of the hydraulic cylinder, the carriage drives the cutting knife to move downward to cut the square textile. The sliding distance of the carriage is limited by the chute, and at the same time, the carriage is prevented from shaking, thereby improving the stability of the cutting knife.

[0010] Furthermore, there are two sets of the gears, racks and sliders, and the two sets of gears, racks and sliders are symmetrically distributed.

[0011] By adopting the above technical solution, when it is necessary to adjust the distance between the two cutting knives, driven by the rotating rod, the gear meshes with the rack, and the rack drives the slider to move towards each other, thereby driving the fixed frame to move, and moving the cutting knife to the required cutting length, so as to achieve the purpose of controlling the specified cutting length.

[0012] Furthermore, the worm gear meshes with the worm.

[0013] By adopting the above technical solution, when it is necessary to adjust the positions of the two cutting knives, the staff rotates the runner. Through the meshing of the worm gear and the worm, the rotating shaft drives the gear to rotate, and the slider drives the tool rest to move to adjust the position of the cutting knife. After the adjustment is completed, the worm gear and the worm are self-locked to prevent the cutting knife from shifting due to the vibration generated during the cutting process.

[0014] Furthermore, there are six sets of the tensioning components, and the six sets of tensioning components are distributed in a counter-bracing manner.

[0015] By adopting the above technical solution, during cutting, the tensioning wheel first contacts the textile, stretches and extends the textile, and at the same time presses the textile to prevent the textile from curling, which facilitates better cutting by the cutting knife. After cutting, under the pulling force of the tension spring, the connecting rod drives the tensioning wheel to lift, so that the tensioning wheel returns to its original position, which is convenient for the next cutting.

[0016] Furthermore, the connecting rod is inclined.

[0017] By adopting the above technical solution, through the inclined setting, it is convenient for the tensioning wheel to stretch the square textile, and it is avoided that the tensioning wheel is concave and collides with the cutting knife, which affects the practicality of the device. At the same time, after cutting, it is convenient for the connecting rod to quickly bounce the tensioning wheel under the pulling force of the tension spring.

[0018] Further, a plurality of grip rods are provided, and the plurality of grip rods are distributed in a circular array.

[0019] By adopting the above technical solution, when cutting is required before and after, the foot pedal drives the traction rod to move, so that the friction disc disengages from the turntable and enters the receiving groove, releasing the limit on the turntable. Hold the grip and push the turntable, and under the drive of the rotating shaft, the textile on the turntable is rotated 180 degrees to cut the other two sides of the square textile.

[0020] Further, the top of the friction disc is in contact with the bottom of the turntable.

[0021] By adopting the above technical solution, after the rotation is completed, release the foot pedal. Under the elastic force of the spring, the spring drives the traction rod back to its original position, and then the top of the friction disc comes into contact with the turntable. By the contact, the friction force between the friction disc and the turntable is increased, avoiding the turntable rotating by itself during the cutting process, resulting in the deviation of the cutting position.

[0022] Further, a soft pad is provided on the top of the turntable, and the soft pad is made of rubber.

[0023] By adopting the above technical solution, rubber has the advantages of good wear resistance, high elasticity, tensile strength and elongation rate, etc. The soft pad buffers the cutting knife, avoiding the chipping of the cutting knife under the pressure, and improving the service life of the cutting knife.

[0024] In summary, the main beneficial effects of the present utility model are as follows:

[0025] 1. By providing an adjustment component in the present utility model, when it is necessary to adjust the specified length for cutting, by rotating the rotating wheel, the rotating rod drives the gear to rotate. Through the meshing of the gear and the rack, under the drive of the slider, the cutting knife is moved to the required cutting length, so as to achieve the purpose of controlling the specified cutting length. At the same time, through the meshing of the worm gear and the worm, self-locking is realized, avoiding the deviation of the cutting knife caused by the vibration during the cutting process;

[0026] 2. By providing a tensioning component in the present utility model, when cutting, the tensioning wheel first contacts the textile, spreads and extends the textile, which is convenient for the cutting knife to cut better, and at the same time presses the textile to avoid the textile curling under the elastic action after cutting;

[0027] 3. By providing a rotating shaft, a grip rod and a turntable in the present utility model, when it is necessary to cut the other two sides, by pushing the grip rod, the turntable rotates, and the textile on the turntable is rotated 180 degrees to cut the other two sides of the square textile. There is no need to manually re-flip and spread the textile, saving manpower and accelerating the cutting efficiency. By the contact between the friction disc and the turntable, the friction force is enhanced, avoiding the turntable rotating by itself during the cutting process, resulting in the deviation of the cutting position.

After the cutting is completed, the hydraulic cylinder 4 drives the carriage 5 to move upward, lifting the cutter 8. At the same time, under the pulling force of the tension spring 903, the connecting rod 902 and the tension wheel 904 are pulled up;

[0046] When it is necessary to cut the other two sides, the foot pedal 1205 is stepped on to drive the traction rod 1203 to move downward, causing the friction disc to disengage from the turntable 11 and enter the receiving groove, releasing the limit on the turntable 11. Then, the turntable 11 is pushed by holding the handle. Driven by the rotating shaft 10, the textile on the turntable 11 is rotated 180 degrees.
