Description

Technical Field

[0001] This utility model relates to an automatic cutting machine, specifically an automatic cutting machine for tent fabric, belonging to the field of tent fabric production technology. Background Technology

[0002] Tarpaulin (or waterproof fabric) is a high-strength, flexible, and waterproof material. It is often used as canvas, polyester with polyurethane coating, or made into polyethylene plastic. Currently, tents on the market come in various sizes, so tent fabric undergoes a cutting process during production.

[0003] Chinese Patent Application Publication No. CN218203584U discloses a cutting device for tent fabric production. The device first manually pulls the tent fabric to straighten it, passes it between the frames, and cuts the tent fabric along the cutting blade. The two parts of the cut tent fabric are glued to the double fabric rollers respectively. As the double fabric rollers rotate, the cut finished tent fabric and the excess tent fabric can be rolled up separately to prevent accumulation and wrinkles.

[0004] Although the above-mentioned patent solution can distinguish and roll up the finished tent fabric and the excess tent fabric, the cutting device in the above-mentioned patent is not convenient for fixing the cut part. Since the fabric is in a taut state during cutting, the cut part of the fabric is prone to pulling, which can easily lead to uneven edges and deviations. Therefore, an automatic tent fabric cutting machine is proposed here. Utility Model Content

[0005] This utility model proposes an automatic tent fabric cutting machine to solve the problem that the cutting device in the prior art is not convenient for fixing the cut part.

An anti-slip pad is fixed on the bottom surface of each pressure rod. A positioning mechanism for driving the two pressure rods to move is provided on the outside of the working plate. The positioning mechanism includes limiting grooves formed at both ends of the pressure rods. A transmission shaft is sleeved inside the limiting groove. A pressing block is fixed at one end of the transmission shaft. A transmission groove is formed inside the pressing block.

Connecting rods are fixedly sleeved at both ends of the transmission plate. The periphery of the connecting rod is rotatably sleeved at the bottom end of the pressing block.

[0008] Furthermore, the positioning mechanism also includes a positioning block fixed to one side of the working plate, one end of which is fixedly sleeved with a limiting rod, and the limiting rod slides inside the transmission groove.

[0009] A roll of fabric is fixed to one side of the working board, and a support frame is fixed to the upper surface of the working board. A groove is provided on the top surface of the support frame, and a cutting mechanism for cutting the fabric is provided on the top surface of the support frame. The cutting mechanism includes a movable sleeve that slides inside the groove, and a transmission rod is slidably connected inside the movable sleeve. A cutting blade is fixed to the bottom end of the transmission rod.

[0010] Furthermore, the cutting mechanism includes a pad fixed to the top of the transmission rod, and a compression spring is fixed between the pad and the movable sleeve, with the compression spring sleeved on the outside of the transmission rod.

[0013] This utility model provides an automatic tent fabric cutting machine, which has the following beneficial effects:

[0014] 1. This automatic tent fabric cutting machine, through the cooperation of the first motor, the driving wheel and the driven wheel, enables the short threaded rod to rotate. Through the cooperation between the short threaded rod and the transmission sleeve, it drives the transmission plate to move up and down below the working plate. Through the cooperation between the transmission plate and the connecting rod, it enables the transmission groove inside the pressing block to slide on the surface of the limiting rod.

[0029] Please refer to this carefully. Figure 2 and Figure 3 The positioning mechanism 5 includes a first motor 501 fixed to the bottom surface of the working plate 1. The output end of the first motor 501 is fixedly sleeved with a drive wheel 502. The drive wheel 502 is meshed with a driven wheel 503.

[0030] The positioning mechanism 5 also includes a positioning block 508 fixed to one side of the working plate 1. One end of the positioning block 508 is fixedly sleeved with a limiting rod 509, and the limiting rod 509 slides inside the transmission groove 513.

[0031] In the above scheme, the short threaded rod 504 can be rotated by the cooperation between the first motor 501, the driving wheel 502 and the driven wheel 503. The short threaded rod 504 can be driven to move the transmission plate 506 up and down below the working plate 1 by the cooperation between the transmission plate 506 and the connecting rod 507. The transmission groove 513 inside the pressing block 510 can slide on the surface of the limiting rod 509 by the cooperation between the transmission plate 506 and the connecting rod 507.

[0032] Please refer to this carefully. Figure 1 and Figure 4 A fabric roll 6 is fixed on one side of the working plate 1, and a support frame 7 is fixed on the upper surface of the working plate 1. A groove 12 is provided on the top surface of the support frame 7, and a cutting mechanism 8 for cutting the fabric is provided on the top surface of the support frame 7. The cutting mechanism 8 includes a movable sleeve 81 that slides inside the groove 12. A transmission rod 82 is slidably connected inside the movable sleeve 81, and a cutting blade is fixed at the bottom end of the transmission rod 82.

[0033] Please refer to this carefully. Figure 4 The cutting mechanism 8 includes a pad 84 fixed to the top of the transmission rod 82. A compression spring 85 is fixed between the pad 84 and the movable sleeve 81, and the compression spring 85 is sleeved on the outside of the transmission rod 82.

[0034] In the above scheme, the compression spring 85 provides elastic support for the pad 84.

[0035] The cutting mechanism 8 also includes two movable plates 83 fixedly sleeved around the movable sleeve 81, and the two movable plates 83 slide on the upper and lower sides of the support frame 7 respectively. A second motor 86 is fixed on the upper surface of the upper movable plate 83, and a transmission block 87 is fixed on the output end of the second motor 86.

[0036] Two support blocks 10 are fixed on the top surface of the support frame 7. A long threaded rod 9 is rotatably sleeved between the two support blocks 10. A connecting block 13 fixed to one side of the moving plate 83 is threaded around the long threaded rod 9.

[0037] In the above scheme, the second motor 86 and the transmission block 87 cooperate to drive the pad 84 to move and drive the transmission rod 82 to slide inside the moving sleeve 81, so that the cutting blade at the bottom of the transmission rod 82 contacts the fabric. The long threaded rod 9 is driven to rotate by external power. The long threaded rod 9 and the transmission block 87 cooperate to drive the moving sleeve 81 to move horizontally.

[0038] In use, the fabric roll 6 is passed through the inside of the support frame 7 and laid flat on the surface of the working plate 1. The size to be cut is measured by the scale rod 4. Then, the first motor 501 is started. Through the cooperation between the first motor 501, the driving wheel 502 and the driven wheel 503, the short threaded rod 504 can be rotated.

Through the cooperation between the pressing block 510, the transmission shaft 511 and the limiting groove 512, the pressure rod 2 can be moved up and down. When the pressure rod 2 moves down, the fabric on both sides of the cutting groove 11 can be fixed to prevent the cutting position from shifting due to the fabric being too tight, thus improving the fabric cutting effect.

[0039] The second motor 86 is started. Through the cooperation between the second motor 86 and the transmission block 87, the pad 84 can be moved, and the transmission rod 82 can be moved to slide inside the moving sleeve 81, so that the cutting blade at the bottom of the transmission rod 82 contacts the fabric. Through external power, the long threaded rod 9 is rotated. Through the cooperation between the long threaded rod 9 and the transmission block 87, the moving sleeve 81 can be moved horizontally and cut. After the cutting is completed, the transmission block 87 continues to rotate, and the compression spring 85 provides elastic support for the pad 84, and drives the transmission rod 82 to reset in preparation for the next cutting.
