Description

Technical Field

[0001] This utility model relates to the field of woven bag processing technology, and in particular to a woven bag tube cutting and breaking device. Background Technology

[0002] Woven bags, also known as snake-skin bags, are a type of plastic bag used for packaging. Their raw materials are generally various chemical plastic materials such as polyethylene and polypropylene. The weaving density refers to the number of warp and weft yarns in a 100mm×100mm woven fabric.

[0003] In the production process of woven bags, the cylindrical structure needs to be closed at one end and then cut to make the woven bag usable. Therefore, this application discloses a woven bag tube cutting and breaking device. Utility Model Content

[0004] The purpose of this invention is to address existing problems by providing a device for cutting and breaking woven bag tubes.

[0005] This utility model is achieved through the following technical solution:

[0006] A woven bag tube cutting and breaking device includes a frame, on which a plate frame is mounted. Rollers are symmetrically and rotatably connected at both ends of the plate frame. An anvil is connected to the middle of the plate frame. A cutting disc of a cutting mechanism is arranged directly above the anvil. The movable seat of the cutting mechanism is fitted onto the guide rod and support rod of a driving mechanism. The driving mechanism is mounted on a bracket. Clamping mechanisms are symmetrically arranged on both sides of the anvil. The clamping seats of the clamping mechanisms are connected to the inner side of the plate frame at both ends.

[0007] As a further improvement to the above solution, the cutting mechanism includes a cutter disc, which is rotatably connected to a cutter holder. A drive motor is connected to the outside of the cutter holder, and the working rod of a hydraulic cylinder is connected to the top of the cutter holder. The hydraulic cylinder is mounted on a movable seat.

[0008] The machine uses a motor to drive the cutter head to rotate, and a hydraulic cylinder to move the cutter head closer to or away from the anvil, so as to cut the woven bag tube.

[0009] As a further improvement to the above solution, the drive mechanism includes a movable seat, on which a guide rod and a support rod are symmetrically sleeved. The ends of the guide rod and the support rod are symmetrically connected to an end plate, and the end plate is connected to a bracket. A wheel groove is provided on one side of the movable seat, and a gear is provided in the wheel groove. The gear meshes with a rack, and the rack is installed on the top surface of the support rod. The gear is sleeved on the output shaft of the second motor, and the second motor is installed on the movable seat.

[0010] The second motor rotates to drive the gear to rotate, and the gear rolls on the rack. At the same time, it drives the movable seat to slide on the smooth plate. The movable seat slides on the smooth rod and the support rod, which in turn drives the cutter head to move. The servo function of the second motor drives the movable seat to move back and forth. In addition, a safety switch on the end plate prevents the movable seat from hitting the end plate and switches between forward and reverse rotation.

[0011] As a further improvement to the above solution, the clamping mechanism includes a clamping seat, on which slide rods are symmetrically and movably mounted. The upper end of the slide rod is connected to a pressure plate, and a spring is mounted on the slide rod between the pressure plate and the clamping seat. The lower end of the slide rod is connected to the working rod of a cylinder, and the cylinder is installed on the lower surface of the clamping seat. A clamping strip is installed on the lower surface of the pressure plate.

[0012] The cylinder operates synchronously, causing the slide bar to move downwards. The slide bar then moves the pressure plate, and the clamping strip moves with the pressure plate. Together with the clamping seat, the strip clamps and fixes the two sides of the cut section of the woven bag tube, preventing the two sides of the cut section from moving and facilitating the smooth cutting process.

[0013] As a further improvement to the above solution, a slit is provided through the cutting board, and the slit matches the annular blade of the cutting disc.

[0014] The woven bag tube is cut by using a rotating cutter head housed in the cutting slot.

[0015] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. The rotation of the cutter head, combined with the hydraulic cylinder driving the cutter head, motor, and cutter holder, causes the cutter head to move closer to or away from the woven bag tube passing through the anvil. The cutter head moves down to the cutting seam to cut the woven bag tube. At the same time, the drive mechanism moves on the guide rod and support rod, causing the cutter head to move back to its original position during rotation. In addition, the clamping mechanism fixes the two sides of the woven bag tube during cutting. It has the effects of excellent cutting effect, fast cutting speed, and thorough cutting.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figures 1 to 3As shown, a woven bag tube cutting and breaking device includes a frame 1, on which a plate frame 2 is mounted. Rollers 3 are symmetrically and rotatably connected at both ends of the plate frame 2. An anvil 5 is connected to the middle of the plate frame 2. A cutting disc 71 of a cutting mechanism 7 is arranged directly above the anvil 5. The movable seat 74 of the cutting mechanism 7 is fitted onto the guide rod 81 and support rod 83 of the driving mechanism 8. The driving mechanism 8 is mounted on a bracket 9. Clamping mechanisms 4 are symmetrically arranged on both sides of the anvil 5. The clamping seats 41 of the clamping mechanisms 4 are connected to the inner side of the plate frame 2 at both ends.

[0021] As a further improvement to the above solution, the cutting mechanism 7 includes a cutter head 71, which is rotatably connected to a cutter holder 72. A drive motor 73 is connected to the outside of the cutter holder 72, and the working rod of a hydraulic cylinder 75 is connected to the top of the cutter holder 72. The hydraulic cylinder 75 is mounted on a movable seat 74.

[0022] The cutting disc 71 is driven to rotate by the motor 73 and moved by the hydraulic cylinder 75, so that the cutting disc 71 approaches or moves away from the anvil 5, thereby cutting the woven bag tube.

[0023] As a further improvement to the above solution, the drive mechanism 8 includes a movable seat 74, on which a guide rod 81 and a support rod 83 are symmetrically sleeved. The ends of the guide rod 81 and the support rod 83 are symmetrically connected to an end plate 82, which is connected to a bracket 9. A wheel groove 87 is provided on one side of the movable seat 74, and a gear 85 is provided in the wheel groove 87. The gear 85 meshes with a rack 84, which is mounted on the top surface of the support rod 83. The gear 85 is sleeved on the output shaft of a second motor 86, which is mounted on the movable seat 74.

[0024] The rotation of motor 86 drives gear 85 to rotate, and gear 85 rolls on rack 84. At the same time, it drives movable seat 74 to slide on the smooth plate. Movable seat 74 slides on smooth rod 81 and support rod 83, thereby driving the cutter head 71 to move. The servo function of motor 86 drives movable seat 74 to move back and forth. In addition, safety switch 88 on end plate 82 prevents movable seat 74 from hitting end plate 82 and switches between forward and reverse rotation.

[0025] As a further improvement to the above solution, the clamping mechanism 4 includes a clamping seat 41, on which slide rods 46 are symmetrically and movably mounted. The upper end of the slide rods 46 is connected to the pressure plate 44. A spring 43 is mounted on the slide rods 46 between the pressure plate 44 and the clamping seat 41. The lower end of the slide rods 46 is connected to the working rod of the cylinder 42. The cylinder 42 is installed on the lower surface of the clamping seat 41. A clamping strip 45 is installed on the lower surface of the pressure plate 44.

[0026] The cylinder 42 works synchronously to drive the slide bar 46 to move downward. The slide bar 46 drives the pressure plate 44 to move. At the same time, the clamping bar 45 moves with the pressure plate 44 and works with the clamping seat 41 to clamp and fix the two sides of the cut part of the woven bag tube, so that the two sides of the cut part of the woven bag tube cannot move, which is conducive to the smooth progress of the cutting work.

[0027] As a further improvement to the above solution, a slit 6 is provided through the anvil 5, and the slit 6 matches the annular blade of the blade disc 71.

[0028] The rotating cutter head 71, housed within the slit 6, is used to cut the woven bag tube.

[0029] The working principle of a woven bag tube cutting and breaking device: The rotation of the cutter head 71, in conjunction with the hydraulic cylinder 75, drives the cutter head 71, motor 73, and cutter holder 72 to move, so that the cutter head 71 approaches or moves away from the woven bag tube passing through the anvil 5. The cutter head 71 moves down to the cutting slit 6 to cut the woven bag tube. At the same time, the drive mechanism 8 moves on the guide rod 81 and the support rod 83, so that the cutter head 71 moves back to the original position during rotation. In addition, the clamping mechanism 4 fixes the two sides of the woven bag tube during cutting.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
