Description

Technical Field

[0001] This utility model relates to the field of cloth bag processing and cutting technology, specifically a circular cutting machine for cloth bag processing. Background Technology

[0002] Dust collector bags are the core component of industrial dust collection equipment, used to capture and filter dust particles in dust-laden gas. During the bag manufacturing process, the fabric used to make the bags needs to be cut, and then the cut fabric is processed into cylinders or rectangles of a specific diameter and length.

[0003] The existing fabric bag cutting device includes a placement table, a fixed frame mounted on the placement table, a pneumatic cylinder mounted on the top side of the fixed frame, a pneumatic rod mounted on the actuating end of the pneumatic cylinder, a mounting plate fixed to the bottom end of the pneumatic rod, and a cutting blade mounted on the bottom side of the mounting plate. When cutting the fabric, the fabric to be cut is first placed on the placement table, and then the pneumatic cylinder is activated, causing the pneumatic rod to drive the cutting blade downward until the cutting blade cuts the fabric used to make the bag.

[0004] Existing fabric bag cutting devices lack a smoothing mechanism, failing to effectively pre-treat the fabric during cutting. This results in wrinkles in the fabric, making it difficult for the cutting blade to cut accurately due to the unevenness of the fabric. The cuts are often uneven and rough, severely affecting cutting accuracy and quality. Furthermore, during continuous fabric cutting, the blade gradually dulls, requiring greater force to cut the fabric. This not only accelerates blade wear but may also cause the fabric to be pulled or torn, resulting in rough edges and reduced cutting quality. Therefore, a circular cutting machine for fabric bag processing 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 circular cutting machine for bag processing.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A circular cutting machine for fabric bag processing, comprising a support base, a fixed frame mounted on the support base, two pneumatic cylinders mounted on the top side of the fixed frame, each pneumatic cylinder having a pneumatic rod mounted on its working end, and a mounting plate fixedly connected to the bottom end of each pneumatic rod. A cutting blade is mounted on the bottom side of the mounting plate. Fixed seats are mounted on both side walls of the mounting plate, and a swing frame is hinged within each of the two fixed seats. A connecting block is hinged to the other end of each swing frame, and a mounting seat is fixedly connected to the connecting block. A smoothing roller is rotatably mounted within the mounting seat. Two fixed blocks are fixedly connected to the top sides of each of the two fixed seats, and the two fixed blocks are fitted together. The device has a frame, with three first springs fixed between the frame and the swing frame. A control panel is installed on one side wall of the fixed frame, which is used to control the start and stop of the pneumatic cylinder. During cutting, by setting a smoothing mechanism, the pneumatic cylinder is activated, causing the mounting plate to move the cutting blade and the smoothing mechanism downward. The smoothing rollers on both sides are in contact with the fabric beforehand. As the cutting blade continues to move downward, with the cooperation of the first springs, the swing frame drives the smoothing rollers on both sides to expand outward, thereby effectively flattening the fabric, eliminating wrinkles, and keeping the fabric in a relatively taut and flat state. This allows the cutting blade to cut into the fabric more accurately and smoothly, ensuring a neater and smoother cut, greatly improving the cutting accuracy and quality.

[0007] Preferably, a sharpening mechanism is provided at the bottom of the support base. The sharpening mechanism includes two fixed bending frames. The two fixed bending frames are fixedly connected to the bottom side of the support base, and the two fixed bending frames are respectively located on both sides of the cutting groove. A sharpening stone is hinged in each fixed bending frame. A connecting plate is fixedly connected between the two sides of each fixed bending frame. Three second springs are fixedly connected between the connecting plate and the sharpening stone. During the continuous fabric cutting process, the blade will gradually become dull. By setting up the sharpening mechanism, when the cutting knife moves down to cut the fabric each time, the blade will simultaneously pass through the gap between the two sharpening stones. The elastic force of the second springs keeps the sharpening stone in contact with both sides of the blade, and the sharpening operation is completed during the cutting action. This structure allows the blade to be sharpened once every time the cutting knife makes a cutting action, always keeping the blade sharp. The sharp blade can cut the fabric fibers more easily and cleanly, making the edges of the cut fabric neat and smooth, without burrs or tears, greatly improving the cutting quality.

[0008] Preferably, the support base has a cutting groove, which is located directly below the cutting blade. The top two sides of the support base are equipped with scale markings. When using the device, the cutting groove ensures that the fabric is completely cut; the scale markings facilitate the cutting of the fabric to a fixed length.

[0009] Preferably, two bent plates are fixedly connected to one end of each support base, and a U-shaped bracket is fixedly connected to the top of each of the two bent plates. The fabric roll is movably installed on the two U-shaped brackets. When using the device, the fabric roll serves as the raw material carrier for the processing of dustproof bags. The fabric is released by rotation, providing a continuous and stable raw material input for cutting. By setting the U-shaped brackets, it is convenient to quickly install, replace and disassemble the fabric roll.

[0010] Preferably, two fixed plates are fixedly connected to the support base, and guide rollers are rotatably installed between the two fixed plates. When using the device, the guide rollers facilitate the guidance and conveying of the fabric.

[0011] The advantages of this utility model are: 1. During cutting, this utility model uses a smoothing mechanism to activate a pneumatic cylinder, causing the mounting plate to move the cutting blade and smoothing mechanism downwards. The smoothing rollers on both sides are in contact with the fabric beforehand. As the cutting blade continues to move downwards, the swing frame, in conjunction with the first spring, causes the smoothing rollers on both sides to expand outwards, thereby effectively flattening the fabric, eliminating wrinkles, and keeping the fabric in a relatively taut and flat state. This allows the cutting blade to cut into the fabric more accurately and smoothly, ensuring a neater and smoother cut, greatly improving the cutting accuracy and quality. 2. In the continuous fabric cutting process, the blade will gradually become dull. By setting up a sharpening mechanism, the blade will simultaneously pass through the gap between two sharpening stones each time the cutting knife moves down to cut the fabric. The elastic force of the second spring keeps the sharpening stones in contact with both sides of the blade, completing the sharpening operation during the cutting action. This structure ensures that the blade is sharpened once with each cutting action, always keeping the blade sharp. The sharp blade can cut the fabric fibers more easily and cleanly, making the cut fabric edges neat and smooth, without burrs or tears, greatly improving the cutting quality.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0015] Please see Figure 1 and Figure 3-5 As shown, a circular cutting machine for fabric bags includes a support base 1, a fixed frame 2 mounted on the support base 1, two pneumatic cylinders 3 mounted on the top side of the fixed frame 2, each pneumatic cylinder 3 having a pneumatic rod mounted on its actuating end, and a mounting plate 4 fixedly connected to the bottom end of each pneumatic rod. A cutting blade 5 is mounted on the bottom side of the mounting plate 4. Fixed seats 6 are mounted on both side walls of the mounting plate 4, and swing frames 7 are hinged to both fixed seats 6. A connecting block 8 is hinged to the other end of each swing frame 7, and a mounting seat 9 is fixedly connected to the connecting block 8. A smoothing roller 10 is rotatably mounted inside the mounting seat 9. Two fixed blocks 11 are fixedly connected to the top sides of both fixed seats 6, and the two fixed blocks 11 cooperate... A frame 12 is installed, and three first springs 13 are fixed between the frame 12 and the swing frame 7. A control panel 24 is installed on one side wall of the fixed frame 2, and the control panel 24 is used to control the start and stop of the pneumatic cylinder 3. When cutting the cloth bag, the cloth roll 21 to be cut is first clamped between two U-shaped clamps 20 to facilitate a continuous and stable raw material input for subsequent cutting. Then, the free end of the cloth is passed through the bottom of the guide roller 23 and the cloth is moved on the top side of the support 1. The scale mark 25 is aligned with the cloth until the free end of the cloth moves to a distance that meets the cutting length requirement between it and the cutting blade 5. Then the cutting operation can be carried out. During the cutting process, fabric wrinkles can cause uneven edges and inaccurate dimensions. By setting up a smoothing mechanism and activating the pneumatic cylinder 3, the pneumatic rod moves the mounting plate 4 downward, which in turn moves the cutting blade 5 and the smoothing mechanism downward. The smoothing rollers 10 on both sides are in contact with the fabric beforehand. As the cutting blade 5 continues to move downward, the swing frame 7, in conjunction with the first spring 13, causes the smoothing rollers 10 on both sides to expand outward, which can effectively flatten the fabric, eliminate wrinkles, and keep the fabric in a relatively taut and flat state. This allows the cutting blade 5 to cut into the fabric more accurately and smoothly, ensuring a neater and smoother cut, which greatly improves the cutting accuracy and quality. Please see Figure 2-6 As shown, a sharpening mechanism is provided at the bottom of the support base 1. The sharpening mechanism includes two fixed bending frames 15. Two fixed bending frames 15 are fixedly connected to the bottom side of the support base 1, and the two fixed bending frames 15 are respectively located on both sides of the cutting groove 14. A sharpening stone 16 is hinged in each fixed bending frame 15. A connecting plate 17 is fixedly connected between the two sides of each fixed bending frame 15. Three second springs 18 are fixedly connected between the connecting plate 17 and the sharpening stone 16. During operation, the blade will gradually become dull during the continuous fabric cutting process. By setting... The cutting blade 5 is equipped with a sharpening mechanism. Each time the cutting blade 5 moves down to cut the fabric, the blade edge passes through the gap between the two sharpening stones 16 simultaneously. The elastic force of the second spring 18 keeps the sharpening stones 16 in contact with both sides of the blade edge, completing the sharpening operation during the cutting action. This structure ensures that the cutting blade 5 is sharpened once for each cutting action, keeping the blade edge sharp. The sharp blade edge can cut the fabric fibers more easily and cleanly, resulting in neat and smooth edges of the cut fabric without burrs or tears, greatly improving the cutting quality. The support base 1 has a cutting groove 14, which is located directly below the cutting blade 5. The top two sides of the support base 1 are equipped with scale marks 25. When the device is in operation, the cutting groove 14 ensures that the fabric is completely cut. The scale marks 25 facilitate the cutting of the fabric to a fixed length. Please see Figure 1-2 As shown, two bent plates 19 are fixedly connected to one end of the support base 1, and U-shaped brackets 20 are fixedly connected to the top of the two bent plates 19. Fabric rolls 21 are movably installed on the two U-shaped brackets 20. Two fixing plates 22 are fixedly connected to the support base 1, and guide rollers 23 are rotatably installed between the two fixing plates 22. When the device is used, the fabric rolls 21 serve as the raw material carrier for the processing of dustproof bags. The fabric is released by rotation, providing a continuous and stable raw material input for cutting. The U-shaped brackets 20 facilitate the quick installation, replacement and disassembly of the fabric rolls 21. Working Principle: Existing fabric bag cutting devices lack a smoothing mechanism, failing to effectively pre-treat the fabric during cutting. This results in wrinkles in the fabric, making it difficult for the cutting blade 5 to cut precisely when it enters the material due to the unevenness. The cuts are often uneven and rough, severely affecting cutting accuracy and quality. Furthermore, during continuous fabric cutting, the blade gradually dulls, requiring greater force to cut the fabric. This not only accelerates blade wear but may also cause the fabric to be pulled or torn, resulting in poor quality. Rough edges appear on the material, reducing the cutting quality; therefore, a circular cutting machine for fabric bag processing is proposed to address the above problem; when cutting the fabric bag, the roll 21 of fabric to be cut is first clamped between two U-shaped clamps 20 to facilitate a continuous and stable input of raw materials for subsequent cutting. Then, the free end of the fabric is passed through the bottom of the guide roller 23 and the fabric is moved on the top side of the support 1. The scale mark 25 is aligned with the fabric until the free end of the fabric moves to a distance that meets the cutting length requirement between it and the cutting blade 5, and then the cutting operation can be carried out. During the cutting process, fabric wrinkles can cause uneven edges and inaccurate dimensions. By setting up a smoothing mechanism and activating the pneumatic cylinder 3, the pneumatic rod moves the mounting plate 4 downward, which in turn moves the cutting blade 5 and the smoothing mechanism downward. The smoothing rollers 10 on both sides are in contact with the fabric beforehand. As the cutting blade 5 continues to move downward, the swing frame 7, in conjunction with the first spring 13, causes the smoothing rollers 10 on both sides to expand outward, which can effectively flatten the fabric, eliminate wrinkles, and keep the fabric in a relatively taut and flat state. This allows the cutting blade 5 to cut into the fabric more accurately and smoothly, ensuring a neater and smoother cut, which greatly improves the cutting accuracy and quality. During the continuous fabric cutting process, the blade will gradually become dull. By setting up a sharpening mechanism, the blade of the cutting blade 5 will simultaneously pass through the gap between the two sharpening stones 16 each time it moves down to cut the fabric. The elastic force of the second spring 18 keeps the sharpening stones 16 in contact with both sides of the blade, completing the sharpening operation during the cutting action. This structure ensures that the blade of the cutting blade is sharpened once every time it makes a cutting action, keeping the blade sharp at all times. The sharp blade can cut the fabric fibers more easily and cleanly, making the edges of the cut fabric neat and smooth, without burrs or tears, greatly improving the cutting quality.
