Description

Technical Field

[0001] The invention belongs to the technical field of fabric cutting, and in particular relates to a fabric positioning and cutting device. Background Art

[0002] Fabric is the primary material used in the production of clothing and other fabric products. Textile yarn is processed on textile machines and subsequently printed and dyed to create a specific style of fabric. This fabric is then rolled up on cloth rollers for easy transportation. During the production and processing of clothing and other fabric products, the rolled fabric needs to be unrolled and laid on a cutting machine for cutting according to the design to facilitate the subsequent sewing of the garment or fabric product. Existing fabric cutting processes can easily cause wrinkles and sagging on the fabric surface, affecting the actual cutting effect. Summary of the Invention

[0003] The purpose of the present invention is to provide a technical solution for a fabric positioning and cutting device to address the shortcomings of the existing technology. The structural design is ingenious and reasonable. The fabric is transported smoothly by the discharge roller group. At the same time, the fabric is stretched and tensioned by the feed roller group during fabric transportation, effectively avoiding wrinkles and warping in the fabric transmission. After the fabric is stretched, it is flattened by the leveling roller group to make the fabric further flat. After the discharge roller group finishes discharging, the end of the fabric is clamped by the end clamping group to make the fabric stretched and straightened, and then the fabric is cut by the cutting component, effectively avoiding wrinkles and loosening of the fabric during cutting, and ensuring the cutting effect of the fabric.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A fabric positioning and cutting device comprises a cutting table and a cutting assembly, and further comprises a blowing chamber, which is arranged at the discharge end of the cutting table and is fixedly connected to the cutting table through a connecting plate, and a blowing plate group is provided on the blowing chamber, and the cut fabric is blown by the blowing plate group; a discharge roller group is provided at the feed end of the cutting table, and the fabric is wound on the discharge roller group; a leveling roller group is provided between the discharge roller group and the cutting table, and a feeding roller group is provided between the leveling roller group and the discharge roller group; an end clamping group is provided at the discharge end of the cutting table, and the end clamping group is fixed to the cutting table. The end clamping group clamps the fabric; the structural design is ingenious and reasonable, and the fabric is transported smoothly by the unwinding roller group. At the same time, the fabric is stretched and tensioned by the feeding roller group during fabric transportation, effectively avoiding wrinkles and warping in fabric transmission. After the fabric is stretched, it is flattened by the leveling roller group to make the fabric further flat. After the unwinding roller group finishes unwinding, the end of the fabric is clamped by the end clamping group to make the fabric stretched and straightened, and then the fabric is cut by the cutting component, effectively avoiding wrinkles and loosening of the fabric during cutting, and ensuring the cutting effect of the fabric.

[0006] Furthermore, the cutting assembly includes a cutting head group and a mounting frame. The cutting head group is arranged on the mounting frame, and the mounting frame is horizontally arranged on the cutting table. Sliders are provided at both ends of the mounting frame. The slides are slidably connected to the side of the cutting table, and the bottom ends of the slides are fixed to the cutting table by a tightening screw. Dovetail slides are provided on both sides of the cutting table, and dovetail slots are provided on the slides. The slides are slidably connected to the dovetail slides through the dovetail slots. A scale is provided on the cutting table, and an indicator block is provided on the slide. Limiting end plates are provided at both ends of the dovetail slide, which play a limiting role on both ends. The dovetail slot cooperates with the dovetail slide to make the sliding adjustment of the slide along the cutting table more stable and reliable, thereby improving the structural stability and reliability. The movement of the slider realizes the overall movement of the cutting assembly, so that the cutting head group can be moved to the set position to realize fixed-length cutting of the fabric. After the slider moves into place, it is fixed by a limit screw, which effectively ensures the structural firmness of the cutting assembly after moving into place. At the same time, during the movement of the slider, the moving position of the cutting assembly is accurately controlled by the scale on the cutting table, and the corresponding scale position after movement is read by the indicator block, so as to accurately control the moving displacement and effectively improve the cutting accuracy. Indicator blocks are set on both sliders, and scales are set on both sides of the cutting table. The scales on both sides correspond to two indicator blocks. The scales can be read from both sides at the same time through the two indicator blocks, which is more convenient for actual reading operations.

[0007] Furthermore, the unloading roller group includes a unloading rack, a unloading roller and a driving member. The unloading roller is arranged between the two unloading racks. The unloading rack includes a unloading seat and a unloading plate. The unloading seat is fixedly connected to the cutting table. The unloading plate is movably inserted into the unloading seat, and the unloading plate is fixed to the unloading seat by a tightening screw. The unloading roller is arranged between the two unloading plates. The unloading roller is used for winding and placing the fabric. The unloading roller is connected to the driving member, and the unloading roller is driven to rotate by the driving member to realize the winding or unwinding of the fabric. The structural design is ingenious and reasonable. The unloading plate is movably inserted in the unloading seat and is fixed in place with two tightening screws to ensure the structural firmness and reliability of the unloading rack after adjustment. The design can appropriately adjust the overall height of the unloading rack, so that the installation height of the unloading roller can be adjusted to make the unloading roller meet the installation requirements and be more conducive to the unwinding and conveying of the fabric. The driving part can adopt a driving motor to drive the unloading roller to rotate through the driving motor to realize the automatic unloading operation of the fabric, which is more conducive to controlling the conveying length of the fabric and facilitating fabric cutting.

[0008] Furthermore, the feed roller group includes a feed rack, feed roller one and feed roller two. The feed rack is fixedly connected to the cutting table. Feed roller one and feed roller two are both arranged between the two feed racks. Feed roller one and feed roller two are staggered up and down. The feed rack realizes the installation of feed roller one and feed roller two, and feed roller one and feed roller two are staggered up and down, so that an inclined angle is formed between the two feed rollers, which is more conducive to the auxiliary transportation of fabrics, and the fabrics can also be stretched and tensioned during transportation, so that the transportation of the fabrics is smoother and more stable, effectively avoiding warping and wrinkles during fabric transportation.

[0009] The two drive motors correspond to the two leveling rollers, and the two leveling rollers are driven by the two drive motors to rotate synchronously to achieve the leveling operation of the fabric. At the same time, when the fabric is unloaded and needs to be cut, the driving part 2 can drive the two leveling rollers to rotate away from the cutting component, and cooperate with the end clamping group to clamp the end of the fabric, so that the fabric is stretched and straightened on the cutting table, which is more conducive to the cutting operation of the cutting component on the fabric, improves the cutting accuracy, and effectively avoids the wrinkles of the fabric during cutting that affect the cutting effect.

[0010] Furthermore, the end clamping group includes a clamping piece and a connecting rod. The two clamping pieces are respectively arranged at the two ends of the connecting rod. The clamping pieces are fixed to the connecting rod through a limit nut. The two clamping pieces are fixed on the cutting table. The clamping piece includes a bottom support plate and a top pressure plate. A limit column is provided on the bottom support plate. The top pressure plate is sleeved on the limit column, and a locking nut is provided on the end of the limit column. Two card slots are provided at the discharge end of the cutting table. The bottom support plate is matched and connected to the corresponding card slots. A positioning protrusion is provided on the end face of the discharge end of the cutting table. A positioning card slot is provided on the bottom support plate. The positioning card slot matches the positioning protrusion. The bottom support plate is limited and connected to the positioning protrusion through the positioning card slot. The structural design is ingenious and reasonable. Two clamping parts clamp the two corners of the fabric pull-out end respectively, and then the clamping parts are limited and connected to the positioning protrusions, thereby limiting and fixing the fabric pull-out end. The flattening roller group then reverses the fabric transmission, making the fabric on the cutting table taut and straight before cutting, effectively ensuring the cutting effect and quality. The top pressure plate and the bottom support plate clamp the fabric ends, and then lock with the locking nut to effectively ensure the clamping firmness. The structure is simple and easy to use and operate. The bottom support plate is clamped in the slot and cooperates with the positioning slot to be clamped in the positioning protrusion, so that the clamping part is limited and fixed on the cutting table. At the same time, the two clamping parts are connected by a connecting rod and cooperate with the limiting nut and the connecting rod to limit and fix. When the fabric is cut, the connecting rod is directly pulled to completely remove the clamping part from the positioning protrusion and the slot, and then the whole piece is picked up, so that the cut fabric is taken out of the cutting table together with the connecting end clamping group, and then the next blowing operation is carried out. At the same time, the other end clamping group is limited and fixed to the cutting table, so as not to affect the subsequent cutting operation.

[0011] Furthermore, a through slot hole is provided on the top pressure plate, and a pressure piece is provided in the through slot hole, and the pressure piece includes a limit plate, a compression spring and a pressure block, and the compression spring piece is fixedly connected between the limit plate and the pressure block, and the limit plate is limited and supported on the top pressure plate, and the limit plate is fixed to the top pressure plate with screws, and the pressure block is slidably engaged in the through slot hole, and the bottom end of the pressure block extends out of the through slot hole to form a pressure head, and the compression spring piece includes a limit sleeve and a compression spring, and limit sleeves are provided at both ends of the compression spring, and the end of the compression spring is fixedly connected to the limit sleeve, the limit sleeve at the top end of the compression spring is fixedly connected to the limit plate, and the limit sleeve at the bottom end of the compression spring is fixedly connected to the pressure block. There are multiple through slots, and a pressure piece is provided in each through slot. The pressure piece is fixed to the top pressure plate by a limit plate screw to ensure the installation firmness and reliability. The pressure block and the compression spring piece are arranged in the through slot, and under the rebound force of the compression spring piece, the bottom end of the pressure block always extends and protrudes outside the top pressure plate to form a pressure head, so that when the top pressure plate cooperates with the bottom support plate to clamp and fix the end angle of the fabric, the pressure head is also always pressed and limited on the fabric, further improving the clamping firmness and reliability between the clamping piece and the fabric, and the pressure limits of multiple pressure heads effectively ensure the compression and limitation of the fabric. At the same time, the compression spring component is designed, which includes a limit sleeve and a compression spring. Both ends of the compression spring extend into the sleeve hole of the limit sleeve, and the end of the compression spring is fixedly connected to the limit sleeve. The design of the limit sleeves at both ends can facilitate the installation and fixation between the compression spring and the limit plate and the pressure block. At the same time, the limit sleeve can guide the compression spring when it is compressed and deformed, and cooperate with the pressure block to be restricted and guided by the through-slot hole, so that the structure of the pressure component is more stable and reliable.

[0012] Furthermore, two support blocks are provided above the blowing chamber, and both support blocks are provided with support protrusions, which match the positioning slots. The bottom support plate is connected to the support protrusions through the positioning slots. A support column is provided at the top of the support protrusion, and a limit rod is provided on the support column. The limit rod is fixed to the support column by a fastening nut. The structural design is ingenious and reasonable. The two support blocks correspond to the design of the two clamping parts in the end clamping group. The end clamping group can not only clamp and fix the fabric discharge end, but also facilitate the hanging and placement of the cut fabric in the blowing chamber. The end clamping group is supported and placed on the two support blocks in the blowing chamber, and the two clamping parts are respectively placed on the two support blocks. At the same time, the bottom support plate is matched and clamped on the supporting protrusion to achieve precise clamping and positioning of the clamping parts on the support blocks. Then, loosen the fastening nut and rotate the limit lever so that the two ends of the limit lever rotate to coincide with the bottom support plate, tighten the fastening nut, and limit the clamping part to the support block through the limit lever, thereby effectively ensuring the installation firmness and reliability of the end clamping group in the blowing chamber. At the same time, the cut fabric clamped and fixed with the end clamping group is just hung in the blowing chamber, which is convenient for the blowing and shaking operation of the fabric by the blowing plate group.

[0013] Furthermore, two lifting plates are symmetrically arranged on the blowing chamber, and an auxiliary support plate is supported and placed between the two lifting plates. A hanging block is provided in the middle of the connecting rod, and a handshake cavity is provided on the hanging block. The auxiliary support plate matches the handshake cavity, and the design is ingenious. The design of the hanging block and the handshake cavity can facilitate the operator to take the end clamping group, that is, it is convenient to install the end clamping group on the cutting table, and it is also convenient to remove the end clamping group from the cutting table and place it in the blowing chamber. The design is more humane. At the same time, the handshake cavity can cooperate with the auxiliary support plate to provide auxiliary support for the end clamping group hung in the blowing chamber, so that the hanging placement of the cut fabric in the blowing chamber is more stable and reliable.

[0014] Furthermore, there are two groups of blowing plate groups, which are symmetrically arranged on the blowing chamber. The blowing plate groups include blowing plates and guide plates. The blowing plates are arranged on the inner side of the blowing chamber. The blowing plates are evenly distributed along the length direction of the blowing chamber. Blowing slots are evenly arranged on the blowing plates. The blowing plates are connected to the guide plates through connecting pipes. The guide plates are arranged on the outer side of the blowing chamber. The guide plates are provided with air inlet ports. Support legs are provided on all four corners of the guide plates. The support legs are fixed with screws to the outer wall of the blowing chamber. The screws are fixed to ensure that the guide plates The installation is firm and reliable. The two sets of blowing plates blow from both sides of the fabric at the same time, making the fabric shake fully, blowing away the waste and cloth scraps on the surface of the cut fabric, improving the quality of the cut fabric, and making it more convenient for subsequent processing of the fabric. The air supply device and the air inlet pipes on the two guide plates enter the guide plate, and then enter each blowing plate through the connecting pipe, and finally blow out from the blowing slot of the blowing plate and spray onto the surface of the fabric to blow the fabric, making the fabric shake. The structural design is ingenious and reasonable.

[0015] The present invention has the following beneficial effects due to the adoption of the above technical solution:

[0016] The structural design of the present invention is simple and reasonable. The fabric is transported smoothly by the unloading roller group. At the same time, the fabric is stretched and tensioned by the feeding roller group during fabric transportation, effectively avoiding wrinkles and warping in fabric transportation. After the fabric is stretched, it is flattened by the leveling roller group to make the fabric further flat. After the unloading roller group finishes unloading, the end of the fabric is clamped by the end clamping group to make the fabric stretched and straightened, and then the fabric is cut by the cutting component, effectively avoiding wrinkles and looseness in the fabric during cutting, and ensuring the cutting effect of the fabric. The leveling roller group plays a dual role. During the unloading process of the unloading roller group, the two leveling rollers in the leveling roller group rotate towards each other in the direction of the cutting assembly, thereby cooperating with the unloading roller group to make the fabric unloading more stable and level the fabric. After the unloading is completed, when the end clamping group clamps the end of the fabric, the two leveling rollers of the leveling roller group rotate towards each other in the direction away from the cutting assembly, and cooperate with the end clamping group to tighten and straighten the fabric spread on the cutting table, which is more conducive to the cutting operation.

[0034] The unloading roller group 6 includes a unloading rack 17, a unloading roller 18 and a driving member 19. The unloading roller 18 is arranged between the two unloading racks 17. The unloading rack 17 includes a unloading seat 20 and a unloading plate 21. The unloading seat 20 is fixedly connected to the cutting table 1. The unloading plate 21 is movably inserted into the unloading seat 20, and the unloading plate 21 is fixed to the unloading seat 20 by a tightening screw 22. The unloading roller 18 is arranged between the two unloading plates 21. The unloading roller 18 is used for winding and placing the fabric 7.

The structural design is ingenious and reasonable. The discharge plate 21 is movably inserted in the discharge seat 20, and is fixed in position with the tightening screw 22 to ensure the structural firmness and reliability of the discharge rack 17 after it is adjusted into place. The design can appropriately adjust the overall height of the discharge rack 17, so that the installation height of the discharge roller 18 can be adjusted, so that the discharge roller 18 meets the installation requirements and is more conducive to the unwinding and conveying of the fabric 7.

The structural design is ingenious and reasonable. The two clamping members 30 respectively clamp the two end corners of the fabric 7 pulling out, and then the clamping members 30 are limited and clamped in the clamping slots 37. At the same time, the clamping members 30 are limited and clamped on the positioning protrusions 38, thereby limiting and fixing the pulling out end of the fabric 7. Then, in conjunction with the reverse transmission of the fabric 7 by the leveling roller group 8, the fabric 7 on the cutting table 1 is stretched and straightened before the cutting operation is carried out, effectively ensuring the cutting effect and cutting quality. The top pressure plate 34 cooperates with the bottom support plate 33 to clamp the ends of the fabric 7, and then cooperates with the locking nut 36 to lock it, effectively ensuring the clamping firmness. The structure is simple and easy to use and operate. The bottom support plate 33 is clamped in the slot 37 and cooperates with the positioning slot 39 to be clamped in the positioning protrusion 38, so that the clamping member 30 is limited and fixed on the cutting table 1. At the same time, the two clamping members 30 are connected by a connecting rod 31 and cooperate with the limiting nut 32 to be fixed with the connecting rod 31. When the fabric 7 is cut, the connecting rod 31 is directly pulled to completely remove the clamping member 30 from the positioning protrusion 38 and the slot 37, and then the whole is picked up, so that the cut fabric 7 is taken out of the cutting table 1 together with the connecting end clamping group 10, and then the next blowing operation is carried out. At the same time, the other end clamping group 10 is limited and fixed to the cutting table 1, so as not to affect the subsequent cutting operation.
