DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] like Figures 1 to 6As shown, the utility model provides a cutting device for the production of polypropylene film ton bags, including a cutting table 1, a rectangular groove 2 is provided inside the cutting table 1, and limiting grooves 3 are provided on the front and rear sides of the top of the cutting table 1, and the front and rear sides of the top of the cutting table 1 are movably connected with a moving block 4 located at the top of the limiting groove 3, and a movable block 5 is fixedly installed at the bottom of the moving block 4. The bottom of the movable block 5 passes through the limiting groove 3 and extends to the interior of the rectangular groove 2. There are two movable blocks 5, and the bottoms of the two movable blocks 5 are fixedly connected to a rectangular plate 6. The bottom of the rectangular plate 6 is movably connected to the bottom of the inner surface of the rectangular groove 2, and the opposite back surfaces of the two movable blocks 5 are fixedly connected to a spring 7, and the other end of the spring 7 is fixedly connected to the inner surface of the rectangular groove 2. A first motor 8 is fixedly installed on the top of the inner surface of the rectangular groove 2, and the other end of the output shaft of the first motor 8 is fixedly sleeved with a rotating shaft 9, and a convex block 10 is fixedly sleeved on the bottom of the outer surface of the rotating shaft 9.
[0024] When the operator starts the first motor 8, the rotating shaft 9 and the convex block 10 will rotate, so that the outer surface of the convex block 10 squeezes and pushes the outer surfaces of the two rectangular plates 6, so that the two rectangular plates 6 drive the two movable blocks 5 and the motion block 4 to move in opposite directions. At this time, the spring 7 will be compressed, allowing the operator to guide and limit the polypropylene film ton bags of different sizes.
[0025] Among them, a connecting frame 11 is fixedly connected to the right side of the top of the cutting table 1, and a pneumatic cylinder 12 is fixedly installed in the middle of the top of the connecting frame 11. The bottom of the pneumatic cylinder 12 passes through the connecting frame 11 and extends to the outside of the inner surface of the connecting frame 11. A cutting blade 13 is fixedly installed at the bottom of the pneumatic cylinder 12, and support rods 14 are fixedly connected to the four corners of the bottom of the cutting table 1.
[0026] The operator operates the pneumatic cylinder 12, which causes the cutting blade 13 to move downward.
[0027] Among them, a second motor 15 is fixedly installed on the left side of the front of the cutting table 1, and the other end of the output shaft of the second motor 15 is fixedly sleeved with a rotating shaft 16. The outer surface of the rotating shaft 16 is fixedly sleeved with a number one gear 17, and the interior of the number one gear 17 is fixedly sleeved with a first conveying wheel 18 located inside the cutting table 1. The outer surfaces of both ends of the first conveying wheel 18 are movably connected to the interior of the cutting table 1.
[0028] When the operator starts the second motor 15 , the rotating shaft 16 , the first gear 17 and the first conveying wheel 18 rotate.
[0029] Among them, connecting blocks 19 are fixedly installed in the front and rear directions of the left side of the top of the cutting table 1. There are two connecting blocks 19. A second conveying wheel 20 is movably connected between the insides of the two connecting blocks 19. The right end of the second conveying wheel 20 passes through the connecting block 19 and extends to the outside of the connecting block 19 and is fixedly connected with a second gear 21. The outer surface of the second gear 21 is meshed with the outer surface of the first gear 17.
[0030] When the first gear 17 is meshed with the second gear 21 , the second transport wheel 20 is rotated.
[0031] A third motor 22 is fixedly mounted on the right side of the back of the cutting table 1 , and a round shaft 23 is fixedly sleeved on the other end of the output shaft of the third motor 22 .
[0032] When the operator starts the third motor 22 , the circular shaft 23 will rotate.
[0033] The other end of the circular shaft 23 is fixedly connected to a hollow block 24 , a long shaft 25 is movably sleeved inside the hollow block 24 , and the other end of the long shaft 25 is fixedly connected to a pressing plate 26 .
[0034] When the circular shaft 23 drives the hollow block 24 to rotate, the inner surface of the hollow block 24 will squeeze and push the outer surface of the long shaft 25, so that the long shaft 25 drives the pressing plate 26 to move downward.
[0035] Among them, a limit rod 28 located directly in front of the pressure plate 26 is fixedly installed on the top of the front of the cutting table 1. The outer surface of the limit rod 28 is movably connected to the limit block 27, and the back of the limit block 27 is fixedly connected to the front of the pressure plate 26.
[0036] Due to the design of the limiting rod 28 , the movement of the pressing plate 26 is well limited.
[0037] The working principle and use process of this utility model:
[0038] First, the operator operates the first motor 8 and the second motor 15. The operation of the first motor 8 causes the rotating shaft 9 and the convex block 10 to rotate, so that the outer surface of the convex block 10 will squeeze and push the outer surface of the two rectangular plates 6, so that the two rectangular plates 6 drive the two movable blocks 5 and the two motion blocks 4 to move in opposite directions. At this time, the spring 7 is in a compressed state. The operator adjusts the distance between the two motion blocks 4 to place polypropylene film ton bags of equal sizes for guide limiting. Due to the operation of the second motor 15, the rotating shaft 16 drives the number one gear 17 and the first conveying wheel 18 to rotate, so that the outer surface of the number one gear 17 engages with the outer surface of the number two gear 21, and then the number two gear 21 drives the second conveying wheel 20 to rotate. At this time, the first conveying wheel 18 and the second conveying wheel 20 will rotate in opposite directions, thereby being able to convey the polypropylene film ton bags to the right.
[0039] Finally, when the ton bag of polypropylene film is conveyed to the bottom of the pressing plate 26, the operator operates the third motor 22 and the pneumatic cylinder 12. The operation of the third motor 22 causes the circular shaft 23 and the hollow block 24 to rotate, so that the inner surface of the hollow block 24 squeezes and pushes the outer surface of the long shaft 25, so that the long shaft 25 drives the pressing plate 26 to move downward, thereby flattening and fixing the ton bag of polypropylene film on the top of the cutting table 1, preventing inaccurate cutting due to the toughness of the polypropylene film itself during subsequent cutting. The operation of the pneumatic cylinder 12 will cause the cutting blade 13 to move downward, thereby cutting the ton bag of polypropylene film on the top of the cutting table 1.
