Description

Technical Field

[0001] The present application relates to the technical field of cloth processing equipment, and in particular to a cloth cutting device. Background Art

[0002] In the clothing, home furnishing and other industries, it is often necessary to cut a long piece of cloth into the required size for subsequent processing. There is currently a cloth cutting machine that can automatically pull out the cloth and cut it into equal pieces according to the needs, which effectively improves the production efficiency compared to traditional manual cutting.

[0003] However, wrinkles are easily generated in the process of the cloth being pulled, resulting in large errors in the cutter when cutting the cloth. Moreover, since there is no external force to stretch the cloth around, the cutter itself will pull the cloth and deform it when cutting, thereby further increasing the cutting error. Summary of the invention

[0004] In order to improve the defect that wrinkles and deformations are easily generated when cutting cloth, the present application provides a cloth cutting device.

[0005] The present application provides a cloth cutting device, which adopts the following technical solution: A cloth cutting device comprises a frame, a feeding mechanism, a discharging mechanism and a cutting mechanism; the feeding mechanism comprises a feeding belt mounted on the frame and a first pressing assembly arranged above the feeding belt, the discharging mechanism comprises a discharging belt mounted on the frame and a second pressing assembly arranged above the discharging belt, the feeding belt and the discharging belt are arranged at intervals to form a cutting groove for the movement of the cutting mechanism, and a conveying structure for conveying cloth from the feeding belt toward the discharging belt is also arranged in the cutting groove.

[0006] By adopting the above technical scheme, the cloth to be cut is introduced onto the feed belt, and the feed belt conveys the cloth toward the discharge belt, and the conveying structure can guide the cloth passing through the feed belt onto the discharge belt; when the discharge belt conveys the cloth to the position of the required length, the feed belt stops rotating, the first pressing assembly presses the cloth onto the feed belt, and the discharge belt continues to rotate to stretch the cloth more flat; then the discharge belt stops rotating, and the second pressing assembly presses the cloth onto the discharge belt, so that the cloth between the first pressing assembly and the second pressing assembly can be kept in a flat state, and then the cutting mechanism slides in the cutting groove to cut the cloth, which reduces the possibility of wrinkles on the cloth, and also reduces the possibility of pulling and deformation of the cloth when being cut, thereby reducing cutting errors and improving the quality of the finished product.

[0007] Optionally, the cutting mechanism includes a guide rail arranged in the cutting groove and a cutting knife slidably connected to the guide rail; the guide rail has an arc-shaped conveying surface and the guide rail is rotatably connected to the frame to form the conveying structure, and the frame is provided with a rotating part that drives the guide rail to rotate.

[0008] By adopting the above technical solution, the guide rail is arranged between the feeding belt and the discharging belt. When the cloth is pressed by the first pressing assembly and the second pressing assembly, the cutter can move to cut the cloth; moreover, the guide rail is further arranged to be rotatably connected to the frame. When the cutter moves to disengage from the cutting groove, the rotating member drives the frame to rotate, so that the next section of cloth can be conveyed toward the discharging belt through the arc-shaped conveying surface. The structure is simple and the cloth conveying is stable.

[0009] Optionally, the discharge belt is lower than the highest point of the guide rail.

[0010] By adopting the above technical solution, since there will be a certain gap between the rotating guide rail and the discharge belt, setting the guide rail higher than the discharge belt can reduce the possibility of the cloth falling into the gap, ensure that the cloth can fall on the discharge belt due to inertia, and improve the stability of cutting the cloth.

[0011] Optionally, the first pressing assembly includes a pressing part, a tensioning part and a first driving part, the first driving part is used to drive the pressing part and the tensioning part to move vertically, the pressing part can be moved to abut against the feeding belt, and the tensioning part can be moved between the feeding belt and the guide rail.

[0012] By adopting the above technical solution, when the end of the cloth is transferred to the discharge belt by the guide rail, the first driving member drives the clamping component and the tensioning component to move downward, the clamping component presses the cloth against the feed belt, and the tensioning component can continue to move downward in the gap between the feed belt and the guide rail so that the cloth is tightened, further reducing the possibility that the cutter will pull and deform the cloth when cutting the cloth, thereby reducing cutting errors.

[0013] Optionally, the number of the clamping parts is two and they are symmetrically arranged on both sides of the feed belt along the conveying direction; the clamping part includes a first pressure rod connected to the first driving member, the first pressure rod is movably connected to a flattening block at one end away from the first driving member, and the first pressure rod is connected to a first elastic member that drives the flattening block to move toward the center of the feed belt, and after the flattening block abuts against the feed belt, the first pressure rod can continue to move downward and move the flattening block away from the center of the feed belt.

[0014] By adopting the above technical solution, when the cloth is pulled and transmitted to a specified length, the first driving member will drive the first pressure rod to move downward to the flattening block to press the cloth against the feed belt. Then, the first pressure rod will be pushed downward further, and the flattening block will be squeezed by the first pressure rod to move away from the center of the feed belt, that is, the two flattening blocks on the two pressing components will move away from each other, thereby further flattening and tightening the cloth, reducing the possibility of wrinkles on the cloth, and further reducing cutting errors.

[0015] Optionally, the first pressure rod is provided with a first movable groove for the flattening block to move, and the surface of the flattening block is provided with a driving groove, the driving groove has a vertical limiting section and a guide section connected to the limiting section and inclined toward the center direction of the feeding belt, and the first pressure rod is provided with a limiting column on the inner wall of the first movable groove and inserted into the driving groove.

[0016] By adopting the above technical solution, the flattening block can move in the vertical and horizontal directions in the first movable groove, the first elastic member can drive the first pressure rod to remain in the initial state, and the stability of the flattening block in the initial state can be further guaranteed through the cooperation of the driving groove and the limiting column, so that the flattening block can be stabilized at the position closest to the center of the feed belt when it does not contact the feed belt. When the first pressure rod moves downward until the limiting column enters the guide section, it can drive the flattening block to move in the direction away from the center of the feed belt, thereby flattening and tightening the fabric.

[0017] Optionally, the tensioning component includes a second pressure rod connected to the first driving member, and one end of the second pressure rod away from the first driving member is connected to a tensioning rod and a second elastic member driving the tensioning rod to move downward.

[0018] By adopting the above technical solution, the first driving member can simultaneously drive the first pressure rod and the second pressure rod to move downward. When the flattening block at the bottom end of the first pressure rod is pressed against the cloth, the tensioning rod at the bottom end of the second pressure rod is driven by the second elastic member to press the cloth downward into the gap between the feed belt and the guide rail, stretching the cloth tighter, thereby further reducing the possibility of the cutter pulling and deforming the cloth during cutting, and further improving the accuracy of cloth cutting.

[0019] Optionally, the structure of the second pressing assembly is consistent with that of the first pressing assembly, and the second pressing assembly and the first pressing assembly are symmetrically arranged with the axial center plane of the guide rail as the symmetry plane.

[0020] By adopting the above technical solution, when the cloth is pulled and transmitted to a specified length, the parts of the cloth located on the feed belt and the discharge belt are respectively pressed by the first pressing assembly and the second pressing assembly. At the same time, the two tensioning rods press the cloth on both sides of the guide rail downward to tension it, making the cloth on both sides of the cutter less likely to wrinkle and deform, thereby further improving the accuracy of cloth cutting.

[0021] Optionally, a suction mechanism is provided inside the discharge belt, a plurality of through holes are arranged in an array on the discharge belt, the suction mechanism comprises a negative pressure tube, a negative pressure pump connected to the negative pressure tube, and a driving unit for driving the negative pressure tube to reciprocate along the conveying direction of the discharge belt, a plurality of negative pressure holes are arranged in an array on the negative pressure tube, and a side of the negative pressure tube with the negative pressure holes can be attached to the bottom surface of the upper side of the discharge belt.

[0022] By adopting the above technical solution, a movable negative pressure tube is provided on the discharge belt, and a negative pressure pump provides negative pressure to the negative pressure tube. In the initial state, the negative pressure tube is driven by the driving unit to one end close to the feeding belt, and when the cloth is fed to the discharge belt by the guide rail, the negative pressure tube attached to the discharge belt can adsorb the cloth on the discharge belt, thereby improving the stability of transmission; and the driving unit can drive the negative pressure tube to move forward with the discharge belt, so that the cloth can be better conveyed forward, further reducing the possibility of cloth wrinkles, thereby reducing cutting errors.

[0023] Optionally, the guide rail has a rotating shaft rotatably connected to the frame, and the driving unit includes a driving gear, a gear ring and a guide frame, the driving gear is coaxially fixed on the rotating shaft and meshes with the gear ring, the gear ring is rectangular, and the guide frame includes a rectangular frame body and a guide rod connected to the frame body, and the frame is provided with a fixing sleeve for limiting the guide rod from sliding in a horizontal direction; the gear ring is slidably connected to the frame body along the inner wall of the frame, an annular connecting groove is opened on the inner wall of the frame, the gear ring is provided with a connecting column inserted in the connecting groove, and the gear ring is provided with a connecting rod connected to the negative pressure tube.

[0024] By adopting the above technical solution, when the rotating part drives the guide rail to rotate, the driving gear is also driven to rotate. Because the guide frame is restricted by the fixed sleeve and can only move horizontally, the gear ring is also restricted by the connecting groove and the frame when being driven by the driving gear to move, thereby realizing the movement of the rectangular path, that is, the gear ring can drive the negative pressure tube to fit the discharge belt and move forward with the discharge belt to improve the stability of the cloth transmission, and then the negative pressure tube moves downward to a position away from the upper discharge belt, and then moves in the direction away from the transmission of the discharge belt, and returns to fit the side of the upper discharge belt close to the feed belt, so as to absorb the next section of cloth to be cut.

[0025] In summary, the present application includes at least one of the following beneficial effects: 1. The fabric is transmitted from the feed belt to the discharge belt.

[0028] The following is combined with Figure 1-8 This application is described in further detail.

[0029] Reference Figure 1 and Figure 2 The embodiment of the present application discloses a cloth cutting device, including a frame 1, a feeding mechanism 2, a discharging mechanism 3 and a cutting mechanism 4; the feeding mechanism 2 includes a feeding belt 21 installed on the frame 1 and a first pressing assembly 22 arranged above the feeding belt 21; the discharging mechanism 3 includes a discharging belt 31 installed on the frame 1 and a second pressing assembly 32 arranged above the discharging belt 31; the feeding belt 21 and the discharging belt 31 are arranged at intervals to form a cutting groove 5 for the movement of the cutting mechanism 4; and a conveying structure 6 for conveying the cloth from the feeding belt 21 to the discharging belt 31 is also arranged in the cutting groove 5. The cloth is conveyed from the feeding belt 21 to the discharging belt 31, the first pressing assembly 22 and the second pressing assembly 32 flatten and tension the cloth, and the cutter 42 cuts the cloth from the middle, which reduces the possibility of wrinkles on the cloth and the possibility of pulling and deformation when the cloth is cut, thereby reducing the cutting error and improving the quality of the finished product.

[0030] Reference Figure 2 and Figure 3 A loading area 8 is also provided on the frame 1. The cloth to be cut is placed in the loading area 8. The end of the cloth is introduced into the feeding belt 21. The feeding belt 21 conveys the cloth toward the discharge belt 31. The feeding belt 21 and the discharge belt 31 can be made of materials with large friction such as rubber. The feeding belt 21 and the discharge belt 31 both have a driving member for driving the transmission, and the driving member can be a motor assembly.

[0031] Reference Figure 3 and Figure 4 The cutting mechanism 4 includes a guide rail 41 arranged in the cutting groove 5 and a cutter 42 slidably connected to the guide rail 41. The guide rail 41 is preferably a rodless cylinder, which includes a track and a slider. The cutter 42 is fixed to the slider, and the stroke of the cutter 42 is greater than the width of the feed belt 21 and the discharge belt 31. The guide rail 41 is arranged between the feed belt 21 and the discharge belt 31. When the cloth is pressed by the first pressing assembly 22 and the second pressing assembly 32, the cutter 42 can move to cut the cloth. Figure 2The guide rail 41 has an arc-shaped conveying surface 61 and the guide rail 41 is rotatably connected to the frame 1 to form a conveying structure 6. The guide rail 41 can be set to a semi-cylindrical shape, and the semi-circular surface forms a conveying surface 61 that can convey the cloth. In the present embodiment, the guide rail 41 is preferably cylindrical, that is, an anti-slip sleeve can be provided on the rodless cylinder, and the anti-slip sleeve is made of materials such as silicone or rubber to increase the friction between the cloth and the cloth, so as to more stably guide the cloth passing through the feeding belt 21 to the discharge belt 31, and then better flatten the cloth. The surface of the anti-slip sleeve can be provided with a plurality of heat dissipation holes to ensure the heat dissipation effect of the rodless cylinder; a rotating shaft 62 rotatably connected to the frame 1 is axially arranged at both ends of the guide rail 41, and a rotating member 63 is fixed on the frame 1. The rotating member 63 is preferably a motor, and the output shaft of the motor is fixed to the rotating shaft 62 through a coupling. When the cutting knife 42 moves to be out of the cutting groove 5, the rotating member 63 drives the frame 1 to rotate, so that the next section of cloth can be conveyed toward the discharge belt 31 through the circular guide rail 41. The structure is simple and the cloth conveying is stable.

[0032] Preferably, the spacing between the two sides of the guide rail 41 and the feed belt 21 and the discharge belt 31 is 2cm-5cm, and the highest point of the guide rail 41 is flush with the conveying surface of the feed belt 21. Because the rotation directions of the feed belt 21, the guide rail 41 and the discharge belt 31 are consistent, after the end of the cloth is conveyed out of the feed belt 21, the guide rail 41 can receive the cloth and convey it toward the discharge belt 31.

[0033] In order to further improve the stability of the cloth cutting process, on the one hand, the conveying surface of the discharge belt 31 is set to be lower than the highest point of the guide rail 41, so as to reduce the possibility of the cloth falling into the gap between the guide rail 41 and the discharge belt 31, and ensure that the cloth can fall on the discharge belt 31 due to inertia.

[0034] On the other hand, referring to Figure 3 A suction mechanism 7 is also provided inside the discharge belt 31. A plurality of through holes 311 are arranged in an array on the discharge belt 31. The suction mechanism 7 includes a negative pressure tube 71, a negative pressure pump 72 connected to the negative pressure tube 71, and a driving unit 73 for driving the negative pressure tube 71 to reciprocate along the conveying direction of the discharge belt 31. A plurality of negative pressure holes 711 are arranged in an array on the negative pressure tube 71. The negative pressure pump 72 provides negative pressure to the negative pressure tube 71. The side of the negative pressure tube 71 with the negative pressure holes 711 can be attached to the bottom surface of the upper side of the discharge belt 31. In the initial state, the negative pressure tube 71 is driven by the driving unit 73 to one end close to the feeding belt 21. When the cloth is fed to the discharge belt 31 by the guide rail 41, the negative pressure tube 71 attached to the discharge belt 31 can adsorb the cloth on the discharge belt 31, thereby improving the stability of the transmission; and the driving unit 73 can drive the negative pressure tube 71 to move forward together with the discharge belt 31, so that the cloth can be better conveyed forward, further reducing the possibility of wrinkles on the cloth, thereby reducing cutting errors.

[0035] In other embodiments, the driving unit 73 may be configured as a linear driving component such as a cylinder or a hydraulic cylinder to drive the negative pressure tube 71 to perform linear reciprocating motion.

[0036] In this embodiment, in order to reduce the possibility that the cut fabric will be sucked again when the negative pressure tube 71 returns to the direction close to the feeding belt 21, the driving unit 73 preferably drives the negative pressure tube 71 to move along a rectangular path. Figure 4 and Figure 5 Specifically, the driving unit 73 includes a driving gear 731, a gear ring 732 and a guide frame 733. The driving gear 731 is coaxially fixed on the rotating shaft 62 and meshes in the gear ring 732. The gear ring 732 is rectangular. The guide frame 733 includes a rectangular frame body 7331 and a guide rod 7332 connected to the frame body 7331. The number of the guide rods 7332 is two and they are relatively arranged on both sides of the frame body 7331 in the vertical direction. Two fixing sleeves 734 for limiting the sliding of the guide rods 7332 in the horizontal direction are fixed on the frame 1; the gear ring 732 is slidably connected to the frame along the inner wall of the frame body 7331. Inside the body 7331, an annular connecting groove 735 is opened on the inner wall of the frame 1, and a connecting column 7321 inserted in the connecting groove 735 is provided on the gear ring 732, and a connecting rod 7322 connected to the negative pressure tube 71 is provided on the gear ring 732. The connecting rod 7322 extends from the side of the gear ring 732 close to the discharge belt 31, and the end of the connecting rod 7322 away from the gear ring 732 is fixed to the negative pressure tube 71 by fasteners such as bolts. There are two drive units 73 and they are symmetrically arranged on the rotating shaft 62 at both ends of the guide rail 41, so as to improve the stability of the connection structure with the negative pressure tube 71. When the rotating member 63 drives the guide rail 41 to rotate, the driving gear 731 is also driven to rotate. Because the guide frame 733 is restricted by the fixed sleeve 734 and can only move horizontally, the gear ring 732 is also restricted by the connecting groove 735 and the frame 7331 when being driven by the driving gear 731 to move, thereby realizing the movement of the rectangular path, that is, the gear ring 732 can drive the negative pressure tube 71 to fit the discharge belt 31 and move forward with the discharge belt 31 to improve the stability of the cloth transmission, and then the negative pressure tube 71 moves downward to a position away from the upper discharge belt 31, and then moves in the direction away from the transmission of the discharge belt 31. At this time, the negative pressure tube 71 is separated from the discharge belt 31 to reduce the adsorption force on the cloth, so that the cut cloth is smoothly conveyed by the discharge belt 31, and then, the negative pressure tube 71 returns to fit the side of the upper discharge belt 31 close to the feed belt 21, and can adsorb the next section of cloth to be cut.

[0037] In other embodiments, the first pressing assembly 22 may be configured as a pressing plate and a cylinder for driving the pressing plate to move up and down.

[0038] In this embodiment, in order to effectively reduce the occurrence of the cloth being pulled and deformed during cutting, Figure 6The first pressing assembly 22 includes a pressing component 221, a tensioning component 222 and a first driving member 223. The first driving member 223 is used to drive the pressing component 221 and the tensioning component 222 to move vertically. The pressing component 221 can move to abut against the feed belt 21, and the tensioning component 222 can move between the feed belt 21 and the guide rail 41. After the end of the cloth is transferred to the discharge belt 31 by the guide rail 41, the first driving member 223 drives the pressing component 221 and the tensioning component 222 to move downward. The pressing component 221 presses the cloth against the feed belt 21, and the tensioning component 222 can continue to move downward in the gap between the feed belt 21 and the guide rail 41 so that the cloth is tightened, further reducing the possibility that the cutter 42 pulls and deforms the cloth when cutting the cloth.

[0039] Specifically, refer to Figure 6 and Figure 7 There are two clamping parts 221, which are symmetrically arranged on both sides of the feeding belt 21 along the conveying direction; correspondingly, there are also two first driving members 223, which are fixedly installed on the frame 1. The first driving member 223 is preferably a cylinder, and the output shaft of the first driving member 223 is fixed with a horizontal connecting rod 224. The clamping part 221 includes a first pressing rod 2211 fixedly connected to the connecting rod 224, and the first pressing rod 2211 is provided with a first pressing rod 2211 at one end away from the first driving member 223. A movable groove 2214, in which a flattening block 2212 is movably connected, the bottom surface of the flattening block 2212 is covered with an anti-slip pad, and the first pressure rod 2211 is connected to a first elastic member 2213 for driving the flattening block 2212 to move toward the center direction of the feeding belt 21. The first elastic member 2213 can be a rubber pad or a spring. The first elastic member 2213 is preferably a spring, one end of the spring is connected to the inner wall of the first movable groove 2214, and the other end is connected to the flattening block 2212. When the cloth is pulled and transmitted to a specified length, the first driving member 223 will drive the first pressure rod 2211 to move downward to the flattening block 2212 to press the cloth against the feeding belt 21. Then, the first pressure rod 2211 will be pushed downward further, and the flattening block 2212 will be squeezed by the first pressure rod 2211 to move away from the center of the feeding belt 21, that is, the two flattening blocks 2212 on the two pressing components 221 will move away from each other, thereby further flattening and tightening the cloth and reducing the possibility of wrinkles on the cloth.

[0040] In other embodiments, the side of the flattening block 2212 facing away from the first elastic member 2213 can be set as a slope, and the opposite inner wall in the first movable groove 2214 can also be set as a slope parallel to the flattening block 2212, so that the flattening block 2212 can be pushed to move by abutting and squeezing the slope.

[0041] In this embodiment, in order to improve the stability of the flattening block 2212 in the initial state, the flattening block 2212 can be stabilized at the position closest to the center of the feeding belt 21 when it is not in contact with the feeding belt 21; Figure 8 The flattening block 2212 is provided with driving grooves 2215 along two vertically opposite surfaces. The driving groove 2215 has a vertical limiting section 2217 and a guide section 2218 connected with the limiting section 2217 and inclined toward the center of the feeding belt 21. The first pressing rod 2211 is provided with a limiting column 2216 on the inner wall of the first movable groove 2214 and inserted into the driving groove 2215. The flattening block 2212 can move vertically and horizontally in the first movable groove 2214. In the initial state, the limiting column 2216 is located at the top of the limiting section 2217, and there is a gap between the flattening block 2212 and the inner top wall of the first movable groove 2214. When the first pressing rod 2211 moves downward until the limiting column 2216 enters the guide section 2218, the flattening block 2212 can be driven to move in a direction away from the center of the feeding belt 21, thereby flattening and tightening the fabric.

[0042] Reference Figure 6 , Figure 7 and Figure 8 The tensioning component 222 includes a second pressure rod 2221 fixedly connected to the connecting rod 224, and a second movable groove 2224 is formed at one end of the second pressure rod 2221 away from the connecting rod 224. A connecting member 2223 movable along the vertical direction and a second elastic member driving the connecting member 2223 to move downward are arranged in the second movable groove 2224. The second elastic member is preferably a spring, and a tensioning rod 2222 is fixed between the two second connecting members 2223. The width of the tensioning rod 2222 is smaller than the gap between the guide rail 41 and the feeding belt 21. By adopting the above technical solution, the first driving member 223 can simultaneously drive the first pressure rod 2211 and the second pressure rod 2221 to move downward. When the flattening block 2212 at the bottom end of the first pressure rod 2211 is pressed against the cloth, the tensioning rod 2222 at the bottom end of the second pressure rod 2221 is driven by the second elastic member to press the cloth downward into the gap between the feeding belt 21 and the guide rail 41, stretching the cloth tighter, thereby further reducing the possibility of the cutter 42 pulling and deforming the cloth during cutting, and further improving the accuracy of cloth cutting.

[0043] Accordingly, refer to Figure 1The structure of the second pressing assembly 32 is consistent with that of the first pressing assembly 22, and the second pressing assembly 32 and the first pressing assembly 22 are symmetrically arranged with the axial center plane of the guide rail 41 as the symmetry plane. It should be noted that, because the discharge belt 31 will be lower than the discharge belt 31, the stroke of the first driving member 223 on the second pressing assembly 32 is set to be greater than the stroke of the first driving member 223 on the first pressing assembly 22, so as to ensure that the second pressing assembly 32 can press the cloth on the discharge belt 31. When the cloth is pulled and transmitted to a specified length, the cutter 42 also rotates to a vertically upward position along with the guide rail 41, and the parts of the cloth located on the feed belt 21 and the discharge belt 31 are respectively pressed by the pressing assemblies of the first pressing assembly 22 and the second pressing assembly 32. At the same time, the two tensioning rods 2222 press the cloth on both sides of the guide rail 41 downward to tension it, so that the cloth on both sides of the cutter 42 is less likely to wrinkle and deform, thereby further improving the accuracy of cloth cutting.

[0044] The implementation principle of a cloth cutting device in the embodiment of the present application is as follows: The cloth to be cut is introduced onto the feed belt 21, and the feed belt 21 conveys the cloth toward the discharge belt 31. At this time, the cutter 42 is at the end of the guide rail 41 and is separated from the feed belt 21 and the discharge belt 31. The rotating member 63 drives the guide rail 41 to rotate so that the cloth passing through the feed belt 21 can be introduced onto the discharge belt 31. At this time, the negative pressure tube 71 can tightly adsorb the cloth onto the discharge belt 31. When the guide rail 41 rotates, the negative pressure tube 71 is driven to move by the driving unit 73, and the cloth is adsorbed by the negative pressure tube 71 and driven by the discharge belt 31 to be conveyed forward. , then the feeding belt 21 and the discharging belt 31 stop conveying, the cutter 42 rotates to a vertically upward state, the first driving member 223 drives the first pressing rod 2211 and the second pressing rod 2221 to move downward, the flattening block 2212 presses on the cloth and flattens the cloth outward, the tensioning rod 2222 tensions the cloth on both sides of the guide rail 41 downward, and then the cutter 42 slides to cut the cloth, which reduces the possibility of wrinkles on the cloth and the possibility of pulling and deformation when the cloth is cut, thereby reducing the cutting error.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
