Description

Technical Field

[0001] This utility model relates to the technical field of fabric cutting auxiliary equipment, specifically to a fabric cutting auxiliary positioning frame. Background Technology

[0002] In the production process of textiles, apparel and related industries, fabric cutting is an important processing step. Currently, fabric cutting generally adopts traditional operation methods. During cutting, two operators need to simultaneously pull the fabric on the roller to the other side of the cutting table, carefully straighten and smooth the fabric to ensure that it is flat and wrinkle-free. After that, the operators need to return to the cutting position to manually cut the fabric.

[0003] When faced with batch fabric cutting tasks, the aforementioned processes of pulling, straightening, and moving back and forth must be repeated before each cut. This forces operators to frequently move between the rollers, the other side of the cutting table, and the cutting position. This operating mode not only consumes a lot of manpower and time, reducing the production efficiency of fabric cutting, but also causes significant physical exertion for the operators, leading to fatigue and consequently affecting the accuracy and quality of fabric cutting.

[0004] Therefore, there is an urgent need to design an auxiliary positioning frame for fabric cutting to solve the above-mentioned problems existing in the current fabric cutting process. Utility Model Content

[0005] The purpose of this invention is to provide a fabric cutting auxiliary positioning frame to solve the problems mentioned in the background art.

Two slide tables are fixedly installed on the lower surface of the U-shaped slide frame, and the two slide tables are respectively slidably installed on the corresponding slide rails. A hydraulic telescopic rod is fixedly installed between the center of the lower surface of the I-beam frame and the support frame of the cutting table.

[0008] Preferably, four directional rods are fixedly installed on the lower surface of the I-beam frame. The four directional rods are arranged in a rectangular shape on the lower surface of the I-beam frame, and all the directional rods pass through the legs of the cutting table and are slidably connected to the legs.

[0009] Preferably, the clamping device includes two fixed blocks and a motor B fixedly installed on the upper surface of the U-shaped carriage. A shaft is rotatably installed between the two fixed blocks. A pressure plate is sleeved on the outer surface of the shaft. Bolts are fixedly installed between the pressure plate and the shaft.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution:

[0022] A fabric cutting auxiliary positioning frame includes a cutting table 1 with legs on its lower surface, a lifting guide rail 2 inside the cutting table 1, a U-shaped slide 3 slidably mounted on the lifting guide rail 2, the U-shaped slide 3 being located on the outside of the cutting table 1, a reciprocating drive mechanism between the U-shaped slide 3 and the lifting guide rail 2, the reciprocating drive mechanism being used to drive the U-shaped slide 3 to move left and right in the horizontal direction, a clamping device 4 being fixedly mounted on the U-shaped slide 3, the clamping device 4 being used to clamp the fabric, and a fabric roller lifting device 5 being fixedly mounted on the right side of the cutting table 1 by bolts, the fabric roller lifting device 5 being used to hold the fabric roller.

[0023] In actual use, the reciprocating drive mechanism can drive the U-shaped carriage 3 and the clamping device 4 to move to the left through its own structure, thereby pulling the fabric to the left, replacing the operator's manual pulling, avoiding repeated running around, saving labor, and increasing production efficiency. After the fabric is stacked layer by layer on the cutting table 1, the position of the lifting guide rail 2 can be adjusted to adapt to the fabric's placement, effectively meeting the work requirements of fabric laying and cutting.

[0024] Specifically, combined Figure 2As shown, the lifting guide frame 2 includes a frame 21. Two slide rails 22 are fixedly installed on the upper surface of the frame 21. Two connecting plates 23 are installed between the two slide rails 22. The two connecting plates 23 are fixedly installed at the left and right ends of the slide rails 22 respectively. Two slide tables are fixedly installed on the lower surface of the U-shaped slide 3. The two slide tables are slidably installed on the corresponding slide rails 22 respectively. A hydraulic telescopic rod 24 is fixedly installed between the center of the lower surface of the frame 21 and the support frame of the cutting table 1. The extension and retraction of the hydraulic telescopic rod 24 can synchronously drive the frame 21, slide rails 22 and connecting plates 23 to move up and down, thereby driving the U-shaped slide 3 and clamping device 4 to adjust their positions.

[0025] Four directional rods 25 are fixedly installed on the lower surface of the I-beam frame 21. The four directional rods 25 are arranged in a rectangular shape on the lower surface of the I-beam frame 21, and the directional rods 25 pass through the legs of the cutting table 1 and are slidably connected to the legs.

[0026] Combination Figure 1 , Figure 2 and Figure 3 As shown, the reciprocating drive mechanism includes a fixed plate 31, a screw 231, and a motor A232. The fixed plate 31 is fixedly installed between two slides, and the fixed plate 31 is threadedly connected to the screw 231. The screw 231 is rotatably installed between two connecting plates 23. The motor A232 is fixedly installed on the right surface of the right connecting plate 23, and the motor A232 is fixedly connected to the right end of the screw 231 through a coupling. The motor A232 is a forward and reverse servo pulse motor, which is used by connecting to an external power supply and an external controller. The external controller sends pulse signals to the motor A232 to control its operation.

[0027] When motor A232 starts, it can drive the slide table and U-shaped slide 3 to move left and right through the fixed plate 31, thereby driving the clamping device 4 to change its working position.

[0028] Combination Figure 1 , Figure 2 and Figure 3 As shown, the clamping device 4 includes two fixed blocks 41 and a motor B44 fixedly mounted on the upper surface of the U-shaped slide 3. A shaft 42 is rotatably mounted between the two fixed blocks 41. A pressure plate 43 is sleeved on the outer surface of the shaft 42. Bolts are fixedly installed between the pressure plate 43 and the shaft 42. The output end of the motor B44 is fixedly connected to the shaft 42 through a coupling. The motor B44 is also a forward and reverse servo pulse motor, which is used by connecting to an external power supply and an external controller. The external controller sends pulse signals to the motor B44 to control its use.

[0029] Motor B44 can rotate forward or reverse to drive the pressure plate 43 to flip to the right or left, thereby using the cooperation of the pressure plate 43 and the U-shaped slide 3 to clamp and fix the end of the fabric to be pulled.

[0030] Combination Figure 1 and Figure 4 As shown, the fabric roller lifting device 5 includes a support frame 51 fixedly installed on the right side of the cutting table 1. A U-shaped support part 52 is fixedly installed on the upper surface of the support frame 51. The support part 52 is used to provide high-level support for the fabric. Two support blocks 53 are sleeved on the right end of the support frame 51. The support blocks 53 are vertically set on the right end of the support frame 51, and two long rod bolts 54 are fixedly installed between the two support blocks 53. Lifting grooves 531 are opened on the opposite surfaces of the two support blocks 53. Multiple steel balls 532 are rotatably embedded in the lifting grooves 531.

[0031] After placing both ends of the cloth roller into the lifting grooves 531 of the two support blocks 53 respectively, the outer surfaces of both ends of the cloth roller can be made to fit with the outer surfaces of the steel balls 532. When the cloth passes around the support part 52 and is pulled to the left by the clamping device 4, the friction of the cloth roller end in the lifting groove 531 can be reduced by the steel balls 532, so that the cloth pulling work is smoother and silkier.

[0032] Working Principle: During operation, the fabric roller containing the fabric is first placed between two support blocks 53. Next, the fabric needs to be routed around the support part 52 of the support frame 51 and pulled towards the cutting table 1. Then, two operators stand on the front and back sides of the right end of the cutting table 1. Using the external controller of motor A232, motor A232 is started, and the screw 231 drives the two slides and the U-shaped carriage 3 to move to the right between the two slide rails 22 via the connecting plate 23, moving the clamping device 4 in front of the two operators. Then, using the external controller of motor B44, motor B44 is started, and the shaft 42 drives the pressure plate 43 to flip to the left, creating a gap between it and the upper surface of the U-shaped carriage 3. Next, the two operators pinch the front and back corners of the fabric and lay it flat on the upper surface of the U-shaped carriage 3. Then, using motor B44 and the shaft 42, the pressure plate 43 is flipped to the right, clamping and fixing the fabric. The reciprocating drive mechanism moves the clamping device 4 to the left until it reaches the desired position, at which point the reciprocating drive mechanism stops. Two operators then begin cutting the fabric.

[0033] After cutting, the operator holds the right end of the fabric. Motor B44 then drives the pressure plate 43 to flip to the left, releasing the fabric from its grip. Next, the reciprocating drive mechanism moves the clamping device 4 a short distance to the left, disengaging the U-shaped carriage 3 from the fabric, allowing it to naturally fold onto the cutting table 1. Then, the hydraulic telescopic rod 24 moves the slide rail 22, the reciprocating drive mechanism, the U-shaped carriage 3, and the clamping device 4 upwards. Finally, the reciprocating drive mechanism moves the U-shaped carriage 3 and the clamping device 4 to the right, in front of the operator, for the next section of fabric to be pulled and positioned. This entire process allows two operators to work from the same position, avoiding the need for back-and-forth movement, saving effort and improving cutting efficiency.
