Description

Technical Field

[0001] This utility model belongs to the field of fabric cutting technology, specifically relating to a cutting bed correction mechanism. Background Technology

[0002] In the textile, apparel, and home furnishing manufacturing industries, the cutting table is the core equipment for batch cutting of stacked fabrics. Its cutting accuracy directly determines the efficiency of subsequent sewing processes and product quality. During the cutting process, fabrics are prone to wrinkles, edge misalignment, or lateral displacement due to their own material properties (such as flexibility and stretchability), differences in stacked thickness, and the force exerted by the cutting tools. This results in dimensional deviations and uneven edges, which not only increases the workload of subsequent correction processes but may also lead to fabric waste and a decrease in product qualification rate.

[0003] Existing cutting machine pressing and positioning technology has many limitations:

[0004] 1. The positioning method is simple. Most cutting beds only use a pressing structure fixed to the edge to press the fabric at one end, which cannot accurately position the fabric near the cutting area. During cutting, the fabric in this area is prone to displacement due to external force, which affects the cutting effect.

[0005] 2. Limited adaptability: The pressing angle and clamping range of the pressing mechanism cannot be flexibly adjusted according to the thickness of the fabric stack, and there is a lack of effective restriction on the lateral displacement of the fabric, which further aggravates the problem of insufficient cutting accuracy.

[0006] To address this issue, a cutting bed correction mechanism is provided. Utility Model Content

[0007] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a cutting bed correction mechanism to solve the problem that, in the prior art, the fabric in the cutting area is easily displaced by external force during cutting, resulting in insufficient cutting accuracy and affecting the cutting effect.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A cutting bed correction mechanism includes a cutting bed, on which a pressing mechanism A is movably mounted. A drive mechanism for moving the pressing mechanism A left and right to adjust its position is installed inside the cutting bed. An inverted U-shaped frame is fixedly installed on the right side of the upper surface of the cutting bed. A pressing mechanism B is installed inside the inverted U-shaped frame. The pressing mechanism B works in conjunction with the pressing mechanism A to press down and position the right end of the fabric stacked on the cutting bed and the cutting area.

[0010] In the above technical solution, the driving mechanism includes a lead screw rotatably installed inside the cutting bed and a lead screw motor fixedly installed on the right side of the cutting bed. The output end of the lead screw motor is fixedly connected to the right end of the lead screw, and a lead screw slide is sleeved on the outer surface of the lead screw.

[0011] In the above technical solution, two guide rods are fixedly installed inside the cutting bed;

[0012] The pressing mechanism A includes two L-shaped brackets, which are fixedly installed on the front and rear sides of the lead screw slide table, respectively. The L-shaped brackets are slidably sleeved on the outer surface of the corresponding directional guide rods, and the top of the L-shaped brackets is at least 20 centimeters higher than the cutting bed. A rotating shaft is rotatably installed between the upper ends of the two L-shaped brackets. A fine-tuning motor is fixedly installed on the rear surface of the rear L-shaped bracket. The output end of the fine-tuning motor is fixedly connected to the rear end of the rotating shaft. Three bushings are equidistantly sleeved on the outer surface of the rotating shaft. Bolts are fixedly installed between the bushings and the rotating shaft. An adjustable length connecting rod is fixedly installed on the outer surface of the bushing. A pressure rod is fixedly installed between the right ends of the three connecting rods.

[0013] In the above technical solution, the connecting rod includes an inner rod and a sleeve rod. The left end of the inner rod is fixedly connected to the corresponding bushing. The sleeve rod is sleeved on the outer surface of the inner rod, and the upper surface of the sleeve rod is threaded with a tightening bolt.

[0014] In the above technical solution, the front and rear ends of the pressure rod are rotatably mounted with side baffles via hinge shafts. The distance between the two side baffles is the same as the width of the fabric, and multiple damping pads are provided between the side baffles and the hinge shafts.

[0015] In the above technical solution, the pressing mechanism B includes an electric telescopic rod fixedly installed inside the inverted U-shaped frame, a pressure plate fixedly installed on the lower surface of the electric telescopic rod, and a rubber pad fixedly installed on the lower surface of the pressure plate.

[0016] The cutting bed correction mechanism of this utility model has the following advantages compared with the prior art:

[0017] This invention employs a dual positioning structure, where pressing mechanism B fixes the right end of the fabric and pressing mechanism A moves to the vicinity of the cutting area for close-range pressing. This comprehensively constrains fabric displacement, effectively solving the problems of wrinkles and offsets during cutting, and significantly improving cutting accuracy and stability. In addition, the linkage telescopic design adapts to different fabric stacking thicknesses, the micro-adjustment motor precisely controls the pressing angle of the pressure rod, and the side baffle, in conjunction with damping pads, restricts lateral fabric offset, enhancing the equipment's adaptability to diverse scenarios. Overall, through structural optimization, it achieves the dual benefits of dual positioning and strong adaptability. Attached Figure Description

[0022] 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 protection scope of the present utility model.

[0023] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-3 This utility model provides a technical solution:

[0024] A cutting bed correction mechanism includes a cutting bed 1, a pressing mechanism A2 movably mounted on the cutting bed 1, a drive mechanism 3 installed inside the cutting bed 1 for moving the pressing mechanism A2 left and right to adjust its position, an inverted U-shaped frame 12 fixedly mounted on the right side of the upper surface of the cutting bed 1, a pressing mechanism B4 installed inside the inverted U-shaped frame 12, and the pressing mechanism B4 cooperates with the pressing mechanism A2 to press down and position the right end of the fabric stacked on the cutting bed 1 and the cutting part.

[0025] The right end of the fabric is fixed by the pressing mechanism B4, and the pressing mechanism A2 can be moved to the vicinity of the cutting area to press it tightly. The two work together to form a double pressing structure of "right end fixing + cutting area positioning", which can effectively prevent the fabric from wrinkling or shifting due to external force during the cutting process, and significantly improve the cutting accuracy and stability.

[0026] Combination Figure 1As shown, the drive mechanism 3 includes a lead screw 31 rotatably installed inside the cutting bed 1 and a lead screw motor 33 fixedly installed on the right side of the cutting bed 1. The output end of the lead screw motor 33 is fixedly connected to the right end of the lead screw 31, and a lead screw slide 32 is sleeved on the outer surface of the lead screw 31.

[0027] The lead screw drive features high precision and low backlash. The lead screw motor 33 drives the lead screw 31 to rotate, which in turn moves the lead screw slide 32. This enables the pressing mechanism A2 to move smoothly and accurately, ensuring that the pressing mechanism A2 can be precisely adjusted to the optimal pressing position near the cutting area. This avoids errors from manual adjustment and improves the efficiency and accuracy of position adjustment.

[0028] Combination Figure 1 and Figure 2 As shown, two directional guide rods 11 are fixedly installed inside the cutting bed 1. The pressing mechanism A2 includes two L-shaped brackets 21. The two L-shaped brackets 21 are fixedly installed on the front and rear sides of the screw slide table 32, and the L-shaped brackets 21 are slidably sleeved on the outer surface of the corresponding directional guide rods 11. The top of the L-shaped brackets 21 is at least 20 centimeters higher than the cutting bed 1. A rotating shaft 22 is rotatably installed between the upper ends of the two L-shaped brackets 21. A fine-tuning motor 23 is fixedly installed on the rear surface of the rear L-shaped bracket 21. The fine-tuning motor 23 is a forward and reverse motor. The output end of the fine-tuning motor 23 is fixedly connected to the rear end of the rotating shaft 22. Three bushings 221 are equidistantly sleeved on the outer surface of the rotating shaft 22. Bolts are fixedly installed between the bushings 221 and the rotating shaft 22. An adjustable length connecting rod 24 is fixedly installed on the outer surface of the bushings 221. A pressure rod 25 is fixedly installed between the right ends of the three connecting rods 24.

[0029] The directional guide rod 11 provides stable guidance for the L-shaped bracket 21, preventing the pressing mechanism A2 from shaking when it moves and ensuring smooth operation; the height design of the L-shaped bracket 21 avoids interference with the surface of the cutting bed 1 and leaves sufficient space for fabric stacking and cutting operations; the fine-tuning motor 23 drives the rotating shaft 22 to rotate, which can precisely adjust the pressing angle of the pressure rod 25.

[0030] Combination Figure 2 and Figure 3 As shown, the connecting rod 24 includes an inner rod 241 and a sleeve rod 242. The left end of the inner rod 241 is fixedly connected to the corresponding bushing 221. The sleeve rod 242 is sleeved on the outer surface of the inner rod 241, and the upper surface of the sleeve rod 242 is threaded with a tightening bolt.

[0031] The telescopic structure of the inner rod 241 and the sleeve rod 242 can quickly adjust the overall length of the connecting rod 24. With the help of the tightening bolt, the length can be fixed. It can flexibly adapt to the stacking thickness of different fabrics or the distance of the cutting area. The adjustment operation is convenient and the fixation is stable, avoiding the loosening of the connecting rod 24 during the pressing process, which will affect the positioning effect.

[0032] Combination Figure 3As shown, the front and rear ends of the pressure rod 25 are rotatably mounted with side baffles 26 via hinge shafts. The distance between the two side baffles 26 is the same as the width of the fabric, and multiple damping pads 261 are provided between the side baffles 26 and the hinge shaft.

[0033] The spacing of the side baffles 26 matches the width of the fabric, which can limit the lateral displacement of the fabric from the front and rear sides to prevent uneven fabric edges during cutting; the damping pads 261 enable the side baffles 26 to maintain the adjusted angle stably, ensuring that the side baffles 26 do not shake during the pressing process, further improving the stability of the fabric positioning.

[0034] Combination Figure 1 As shown, the pressing mechanism B4 includes an electric telescopic rod 41 fixedly installed inside the inverted U-shaped frame 12, a pressure plate 42 fixedly installed on the lower surface of the electric telescopic rod 41, and a rubber pad 43 fixedly installed on the lower surface of the pressure plate 42.

[0035] The electric telescopic rod 41 drives the pressure plate 42 to quickly press down and lift; the rubber pad 43 can increase the friction between the pressure plate 42 and the fabric, improve the fixing effect, and at the same time avoid the pressure plate 42 directly contacting the fabric to avoid indentation or damage, protect the surface quality of the fabric, and ensure that the right end of the fabric is firmly fixed.

[0036] Working principle: Before use, adjust the extension length of the inner rod 241 and sleeve rod 242 of the connecting rod 24 to match the thickness of the fabric stack and tighten the clamping bolt. When using, first stack the fabric to be cut neatly on the cutting bed 1 and align the edges. Then, start the electric telescopic rod 41 of the pressing mechanism B4 to let the pressure plate 42 with the rubber pad 43 move down to press the right end of the fabric to complete the fixation. Then, according to the position of the cutting area, start the lead screw motor 33 of the drive mechanism 3. Through the lead screw 31 and lead screw slide 32, drive the pressing mechanism A2 to move along the guide rod 11 so that the pressure rod 25 reaches the vicinity of the cutting area. Finally, start the fine adjustment motor 23, which drives the pressure rod 25 to press down through the rotating shaft 22 and connecting rod 24. After pressing the fabric near the cutting area, the stable cutting operation can begin. The close-range pressing combined with double positioning effectively avoids fabric wrinkles and shifts during cutting and improves cutting accuracy.
