Description
Technical Field
[0001] This utility model relates to the technical field of fabric production, and in particular to a fabric cutting and finishing device. Background Technology
[0002] Knitted fabric is a type of fabric made by interlacing yarns, typically produced using a knitting process on a weaving machine. Compared to other types of fabrics, knitted fabrics have greater elasticity and softness. Before winding the fabric, the edges need to be trimmed to ensure a more cohesive roll. Generally, the edges of the fabric are trimmed by a cutting mechanism during the feeding process. However, uneven stress during cutting can easily cause wrinkles in the fabric, resulting in uneven cuts and affecting the fabric's appearance.
[0003] Chinese Patent Publication No. CN218492136U, published on February 17, 2023, discloses a textile fabric cutting device, including a cutting table. Four sets of support legs are fixedly connected to the bottom of the cutting table. A cutter and a U-shaped frame for moving the cutter are arranged above the cutting table. An adjustment mechanism for driving the U-shaped frame to move left and right is arranged below the cutting table. The device is characterized in that: a base is provided below the cutting table, and the bottom of the support legs is fixedly connected to the top of the base; a sliding frame is provided above the cutter, sliding relative to the outer surface of the U-shaped frame; an electric push rod is fixedly installed at the bottom of the sliding frame; the output end of the electric push rod is keyed to the top end of the cutter; a reduction motor is fixedly installed on the rear side of the U-shaped frame, and a positioning screw is keyed to the output end of the reduction motor. The positioning screw has a positioning block threadedly connected to its outer surface. A positioning groove is provided on the top of the U-shaped frame. The left and right sides of the positioning block are slidably connected to the inner wall of the positioning groove. The top and bottom of the positioning block are fixedly connected to the inner wall of the sliding frame. A horizontal plate is slidably connected to the bottom of the cutting table. The front and rear sides of the bottom of the U-shaped frame are fixedly connected to the top of the horizontal plate. A set of spring columns fixedly connected to the top of the horizontal plate is provided on both the front and rear sides of the cutting table. A lifting plate is fixedly connected to the top of the spring columns. A set of lifting grooves is provided on both the front and rear sides of the U-shaped frame. The two sets of lifting plates are slidably connected to the inner walls of the two sets of lifting grooves respectively. Two sets of pressure plates are fixedly connected to the opposite sides of the two sets of lifting plates. A rubber pad for pressing against the textile fabric is fixedly connected to the bottom of the pressure plate. The drawback of this invention is that the device only moves along the upper surface of the textile fabric and flattens the wrinkles through the movement of the rubber pad at the bottom of the pressure plate, making it difficult to ensure uniform force during cutting. Utility Model Content
[0004] The present invention aims to overcome the shortcomings of existing technologies in fabric cutting, which are prone to uneven cuts due to uneven stress. It provides a fabric cutting and finishing device that can tension the fabric before cutting.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fabric cutting and finishing device, comprising: Tensioning components; Support frames are installed at both ends of the tensioning assembly; An extrusion assembly, which is mounted on a support frame; A cutting assembly, which is mounted on a tensioning assembly and positioned between two support frames.
[0006] The fabric slides through the support frame, which holds the fabric at both ends. The extrusion assembly then presses the fabric onto the support frame to secure it. After securing both ends, the tensioning assembly moves the two support frames in opposite directions, tensioning the fabric between them to ensure even stress distribution. Finally, the cutting assembly between the two support frames cuts the fabric, ensuring a clean cut. This process achieves the goal of tensioning the fabric before cutting.
[0007] Preferably, the tensioning assembly includes a base, a dual-axis motor, and tensioning blocks. A sliding block is mounted on the base, and a motor mount is mounted on the sliding block. The dual-axis motor is mounted on the motor mount, and each end of the dual-axis motor has a lead screw. One end of the lead screw is connected to the motor shaft of the dual-axis motor. Each end of the sliding block has a support seat. One end of the lead screw is rotatably connected to the support seat. The support seat is mounted on the sliding block. Two tensioning blocks are provided, each located on one side of the dual-axis motor. Each tensioning block has a sliding groove. The tensioning block is slidably connected to the base through the cooperation of the sliding block and the sliding groove. A meshing sleeve is mounted on the tensioning block, and the lead screw passes through the meshing sleeve and is threadedly connected to it. The tensioning assembly is the main structure of the overall device. It controls the movement of the tensioning blocks by mounting a dual-axis motor on a sliding block 1 on the base. Two tensioning blocks on the base slide along the sliding block 1, positioned on either side of the dual-axis motor. The dual-axis motor controls the synchronous rotation of the lead screws at both ends. The lead screws, through a threaded connection with the meshing sleeve, drive the tensioning blocks to move. The dual-axis motor controls the synchronous rotation of the lead screws on both sides, thus achieving synchronous movement of the tensioning blocks and ensuring uniform force during tensioning. The ends of the lead screws are supported by a support base 1. The dual-axis motor is a common control motor available on the market, capable of synchronous rotation via the motor shafts at both ends. It is readily available through conventional procurement. This design ensures the synchronous movement of the tensioning blocks.
[0008] Preferably, the support frame includes a contact plate and support rods. Several support rods are evenly distributed on the tension block. One end of each support rod is connected to the tension block, and the other end is connected to the contact plate. The support frame is installed on the tension block to support the fabric. The contact plate contacts the fabric and is connected to the top surface of the tension block via the support rods. This design allows the fabric to be lifted.
[0009] Preferably, the extrusion assembly includes a mounting plate, a pneumatic cylinder, and an extrusion plate. The mounting plate is positioned above the contact plate, and limiting rods are provided on both sides of the mounting plate. One end of each limiting rod is connected to the mounting plate, and the other end is connected to the contact plate. The pneumatic cylinder is mounted on the mounting plate, and its pneumatic end is connected to the extrusion plate. By mounting the extrusion assembly on the contact plate above it, and connecting the mounting plate to the contact plate via the limiting rods, the limiting rods on both sides of the contact plate can limit the fabric movement, ensuring that the fabric remains on the contact plate during movement. The top of each limiting rod is connected to the mounting plate. A pneumatic cylinder is mounted on the mounting plate, and the pneumatic cylinder pushes the extrusion plate mounted at the lower end to descend, thus extruding and fixing the fabric. This design effectively secures the fabric.
[0010] Preferably, the bottom surface of the extrusion plate is equipped with several evenly distributed extrusion rods, each with a circular arc cross-section, and the extrusion rods correspond to the contact plate. Directly fixing the fabric via the extrusion plate can easily lead to fabric slippage. Therefore, installing extrusion rods on the bottom surface of the extrusion plate, with their circular arc cross-sections, allows for better fabric compression. The extrusion rods are made of elastic material, and this elastic compression protects the fabric. This design effectively protects the fabric.
[0011] Preferably, the cutting assembly includes a mounting frame and a sliding block. The mounting frame has a U-shaped cross-section, and both ends are connected to the base. The top surface of the mounting frame has a second sliding groove. A second sliding block is mounted on the sliding block, and the sliding block is slidably connected to the mounting frame through the cooperation of the second sliding block and the second sliding groove. A cutter is mounted on the sliding block. After the fabric is tensioned by the tensioning assembly, the fabric is cut by the cutting assembly. The top surface of the U-shaped mounting frame corresponds to the tensioned fabric. The U-shaped mounting frame is snapped onto the dual-axis motor, positioned precisely in the middle of the fabric. The sliding block can slide along the second sliding groove on the mounting frame. During the sliding process, the cutter on the sliding block can drive the cutting block to cut the fabric. This design allows for the cutting of fabric.
[0012] Preferably, the cutting assembly further includes a second motor, which is mounted on a mounting frame. A second lead screw is mounted on the motor shaft of the second motor, one end of which passes through a sliding block and is threadedly connected to the sliding block. A second support is mounted on the mounting frame, and one end of the second lead screw is rotatably connected to the second support. Manually moving the sliding block can easily lead to instability in the cutting process. Therefore, by mounting the second motor on the mounting frame, the second motor drives the second lead screw to rotate. One end of the second lead screw is supported by the second support. The second lead screw passes through the sliding block and is threadedly connected to it. The rotation of the second lead screw can drive the sliding block to move, thus ensuring a smooth cutting process.
[0013] The beneficial effects of this utility model are: it can tension the fabric before cutting, ensure the synchronous movement of the tensioning blocks, lift the fabric, fix the fabric, protect the fabric, cut the fabric, and achieve a smooth cutting process. Attached Figure Description

A meshing sleeve 19 is mounted on the tensioning block 13. The lead screw 16 passes through the meshing sleeve 19 and is threadedly connected to the meshing sleeve 19.
[0019] The support frame 2 includes a contact plate 21 and a support rod 22. There are several support rods 22, which are evenly distributed on the tension block 13. One end of the support rod 22 is connected to the tension block 13, and the other end of the support rod 22 is connected to the contact plate 21.
[0020] like Figure 3As shown, the extrusion assembly 3 includes a mounting plate 31, a pneumatic cylinder 32, and an extrusion plate 33. The mounting plate 31 is positioned above the contact plate 21. Limiting rods 34 are provided on both sides of the mounting plate 31. One end of the limiting rod 34 is connected to the mounting plate 31, and the other end of the limiting rod 34 is connected to the contact plate 21. The pneumatic cylinder 32 is mounted on the mounting plate 31, and the pneumatic end of the pneumatic cylinder 32 is connected to the extrusion plate 33.
[0021] Several evenly distributed extrusion rods 35 are installed on the bottom surface of the extrusion plate 33. The cross-sectional shape of the extrusion rods 35 is arc-shaped, and the extrusion rods 35 correspond to the contact plate 21.
[0022] like Figure 4 As shown, the cutting assembly 4 includes a mounting frame 41 and a sliding block 42. The mounting frame 41 has a U-shaped cross-section and both ends are connected to the base 11. The top surface of the mounting frame 41 is provided with a sliding groove 43.
