Technical Field

[0001] This utility model relates to the field of flag production trimming technology, specifically a flag production trimming device. Background Technology

[0002] A flag is a piece of cloth with a specific color and pattern that is hung on a pole. During the flag production process, there may be excess or irregular fabric at the edges, so an edge trimming device is needed to remove the excess or irregular fabric at the edges.

[0003] A Chinese patent with publication number CN219342678U discloses a cutting device for knitted fabrics, including a cutting plate. A first fixing block is installed on one side of the cutting plate. A limiting post is fixedly connected to the top of the first fixing block. A limiting sleeve is fitted around the outer ring of the limiting post. A moving block is fixedly connected to one side of the limiting sleeve. A slide rail is provided on the side of the moving block. A slider is installed on the slide rail. A groove corresponding to the slide rail is opened in the slider. A cutting blade is installed on the side of the slider away from the moving block. A handle is installed on the cutting blade. This invention can fix the cutting position of the fabric, so that the fabric is not easily curled or deformed when the cutting blade is cutting, the cutting edge is neat, and the device is simple to operate and highly practical.

[0004] Existing fabric trimming devices are inconvenient to replace worn-out cutting blades. Worn blades can lead to uneven edges and inaccurate dimensions during trimming, thus affecting the overall quality and aesthetics of the flags. Therefore, a new flag production trimming device is proposed to address these issues. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a flag production trimming device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A flag production trimming device of this utility model includes a cutting table; two fixed plates are fixedly connected to the cutting table, each fixed plate has a groove, and a slider is provided in each groove. A lead screw is rotatably installed between the two sliders. A movable block is sleeved on the lead screw. Two limiting rods are fixedly connected between the two sliders, and the two limiting rods are respectively located on the upper and lower sides of the lead screw. The limiting rods pass through the movable block. A mounting frame is fixedly connected to the side wall of the movable block. A first motor is assembled inside the mounting frame. The output end of the first motor is connected to a rotating shaft. A rotating disk is sleeved on the rotating shaft. Four cutting blades are fixed on the outer circumference of the rotating disk. A square plate is installed on the top side of the mounting bracket. The square plate has the same insertion hole as the cutting blade. A rod is inserted into the insertion hole. A second motor is installed on one of the sliders. The output end of the second motor is connected to one end of the lead screw. When changing the blade, the first motor is started, causing the rotating disk to drive the cutting blade to rotate until the new cutting blade to be replaced reaches the lowest point. The first motor then stops working. The rod is then inserted into the insertion hole to further fix the cutting blade. This allows for quick blade replacement, reducing the time spent on work interruption due to blade replacement, thereby improving the overall edge trimming efficiency. The convenient replacement mechanism ensures neat edges, free of burrs and frayed edges, improving the overall quality and appearance of the flag.

[0007] Preferably, pneumatic cylinders are installed at the top of both fixed plates. The working end of each pneumatic cylinder is equipped with a pneumatic rod, and the bottom end of the pneumatic rod is fixed to the slider. When trimming, the pneumatic cylinder is activated, causing the pneumatic rod to drive the slider to move vertically downward, which in turn causes the cutting blade to move downward as well. When the cutting blade moves down to contact the flag fabric, the second motor is activated, causing the lead screw to rotate. With the cooperation of the limit rod, the movable block drives the cutting blade to move stably, thereby completing the flag trimming operation and making the edge of the flag neater and smoother after trimming.

[0008] Preferably, the top side of the cutting table is provided with a cutting groove, and the cutting groove is located directly below the cutting blade. When using the device, by providing the cutting groove, it can be ensured that the cutting blade always moves along a straight line, further ensuring the neatness of the cut.

[0009] Preferably, each fixed plate has a fixed block installed on both sides of its sidewalls, a guide rod fixedly connected to each fixed block and the cutting table, a lifting block sleeved on each guide rod, a spring fixedly connected to each lifting block and its corresponding fixed block, and the spring sleeved on the guide rod. A pressing plate is fixedly connected between two lifting blocks. A through slot is opened on the pressing plate located directly above the cutting groove. Before cutting the edges, the flag to be cut is first fixed, the pressing plate is raised upwards, so that the flag is laid flat on the cutting table, and the hand is removed. Under the rebound force of the spring, the pressing plate can press and fix the flag, avoiding the phenomenon of the flag fabric moving or shifting during the cutting process, thus improving the cutting accuracy.

[0010] The advantages of this utility model are:

[0011] 1. When replacing the cutting blade, the first motor is started, causing the rotating disk to drive the cutting blade to rotate until the new cutting blade to be replaced reaches the lowest point. The first motor then stops operating. The insert rod is then inserted into the insertion hole to further fix the cutting blade, thereby quickly completing the blade replacement and reducing the time interrupted by blade replacement. This improves the overall edge trimming efficiency. The convenient replacement mechanism ensures neat edges, free of burrs and frayed edges, and enhances the overall quality and appearance of the flag.

[0012] 2. Before trimming, this utility model first raises the pressing plate upwards, so that the flag is laid flat on the cutting table. When the hand is removed, the pressing plate can press and fix the flag under the rebound force of the spring, so as to avoid the flag fabric from moving or shifting during the cutting process and improve the cutting accuracy.

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 scope of protection of the present utility model.

[0021] Please see Figure 1-4 As shown, a flag production trimming device includes a cutting table 1; two fixed plates 2 are fixedly connected to the cutting table 1, each fixed plate 2 has a groove 3, and each groove 3 has a slider 4; a lead screw 5 is rotatably mounted between the two sliders 4, and a movable block 7 is sleeved on the lead screw 5; two limiting rods 6 are fixedly connected between the two sliders 4, and the two limiting rods 6 are located on the upper and lower sides of the lead screw 5 respectively, and the limiting rods 6 pass through the movable block 7; a mounting frame 8 is fixedly connected to the side wall of the movable block 7; a first motor 9 is assembled in the mounting frame 8; the output end of the first motor 9 is connected to a rotating shaft; a rotating disk 10 is sleeved on the rotating shaft; four cutting blades 11 are fixed on the outer circumference of the rotating disk 10; a square plate 13 is mounted on the top side of the mounting frame 8, and the square plate 13 is connected to the cutting blades 11. The blade 11 is fitted with the same insertion hole 12, and a rod 14 is inserted into the insertion hole 12. A second motor 15 is installed on one of the sliders 4, and the output end of the second motor 15 is connected to one end of the lead screw 5. When replacing the blade, the first motor 9 is started, which causes the rotating disk 10 to drive the cutting blade 11 to rotate until the new cutting blade 11 that needs to be replaced is rotated to the lowest end. Then the first motor 9 stops working, and the rod 14 is inserted into the insertion hole 12 to further fix the cutting blade 11. This allows for quick replacement of the blade, reduces the time that is interrupted due to blade replacement, and improves the overall edge trimming efficiency. The convenient replacement mechanism ensures neat edges without burrs or frayed edges, improving the overall quality and appearance of the flag.

[0022] Pneumatic cylinders 16 are installed at the top of both fixed plates 2. The working end of the pneumatic cylinder 16 is equipped with a pneumatic rod, and the bottom end of the pneumatic rod is fixed to the slider 4. After the cutter is replaced, when trimming, the pneumatic cylinder 16 is started, so that the pneumatic rod drives the slider 4 to move vertically downward, and the cutting blade 11 also moves downward. When the cutting blade 11 moves down to contact the flag fabric, the second motor 15 is started, so that the lead screw 5 rotates. With the cooperation of the limit rod 6, the movable block 7 drives the cutting blade 11 to move stably, so as to complete the cutting operation of the flag and make the edge of the flag after trimming more neat and smooth.

[0023] The cutting table 1 has a cutting groove 17 on its top side, and the cutting groove 17 is located directly below the cutting blade 11. When using this device, by setting the cutting groove 17, it can be ensured that the cutting blade 11 always moves along a straight line, which further ensures the neatness of the cut.

[0024] Please see Figure 5 As shown, each fixed plate 2 has a fixed block 18 installed on both sides of its side wall. Each fixed block 18 is fixedly connected to the cutting table 1 with a guide rod 19. Each guide rod 19 is fitted with a lifting block 20. Each lifting block 20 is fixedly connected to the corresponding fixed block 18 with a spring 23, and the spring 23 is fitted on the guide rod 19. A pressing plate 21 is fixedly connected between two lifting blocks 20. The pressing plate 21 located directly above the cutting groove 17 has a through groove 22. Before cutting the edges, the flag to be cut is first fixed. The pressing plate 21 is raised upward so that the flag is laid flat on the cutting table 1. The hand is removed. Under the rebound force of the spring 23, the pressing plate 21 can press and fix the flag, preventing the flag fabric from moving or shifting during the cutting process, thus improving the cutting accuracy.

[0025] Working Principle: Existing fabric trimming devices make it difficult to replace worn-out cutting blades 11. Worn blades can lead to uneven edges and inaccurate dimensions, affecting the overall quality and aesthetics of the flag. Therefore, a new flag production trimming device is proposed to address these issues. When replacing the blade, the first motor 9 is activated, causing the rotating disk 10 to rotate the cutting blade 11 until the new blade reaches its lowest point. The first motor 9 then stops, and the insertion rod 14 is inserted into the insertion hole 12 to further secure the cutting blade 11. This allows for quick blade replacement, reducing downtime and improving overall trimming efficiency. The convenient replacement mechanism ensures neat, burr-free, and frayed edges, enhancing the overall quality and appearance of the flag.

[0026] After the blade is replaced, when trimming the edges, first fix the flag to be cut, raise the pressing plate 21 upwards so that the flag is laid flat on the cutting table 1, remove your hand, and under the rebound force of the spring 23, the pressing plate 21 can press and fix the flag, preventing the flag fabric from moving or shifting during the cutting process, thus improving the cutting accuracy. After the flag fabric is pressed and fixed, start the pneumatic cylinder 16, so that the pneumatic rod drives the slider 4 to move vertically downwards, and then the cutting blade 11 also moves downwards. When the cutting blade 11 moves down to contact the flag fabric, start the second motor 15, so that the lead screw 5 rotates. With the cooperation of the limit rod 6, the movable block 7 drives the cutting blade 11 to move stably, thus completing the cutting operation of the flag and making the edge of the flag after trimming more neat and smooth.
