Description

Technical Field

[0001] This utility model relates to the field of ton bag processing technology, specifically a ton bag winding machine. Background Technology

[0002] BOOM (Flexible Intermediate Bulk Container) bags, also known as flexible intermediary bags or FIBCs, are medium-sized bulk containers that, when used with cranes or forklifts, enable unitized transport. They have a large capacity, with a load capacity between 0.5-3 tons and a volume between 500-2300 liters. They are lightweight, have a simple structure, are foldable, and occupy little space when empty. They are moisture-proof, dust-proof, and radiation-resistant. They are easy to load and unload, effectively improving loading and unloading efficiency. They are used for grains, chemical raw materials, and flammable and explosive materials. BOOM bag rewinding machines are specialized equipment for recycling and sorting BOOM bags. They are mainly used to wind, compress, and bundle used BOOM bags for easy transport, storage, or reuse.

[0003] The existing authorized publication number CN219193878U discloses a ton bag winding mechanism, belonging to the field of ton bag processing. It includes: a base plate for placing the entire winding mechanism; an mounting plate fixedly connected to the base plate; a fixed plate fixedly mounted on the mounting plate; a fixed roller rotatably connected to the mounting plate; and a movable roller slidably connected to the mounting plate. This utility model solves the problem of wrinkles appearing after winding due to back-and-forth swaying during the ton bag winding process in the prior art. It limits the front-and-back position of the ton bag during winding, avoiding wrinkles caused by back-and-forth swaying, and effectively ensuring the neatness of the wound result.

[0004] Existing ton bag rewinding machines of this type have the following problems: when rewinding ton bags, loosening and slippage may occur during the winding process, and they cannot adapt to rewinding rollers of different diameters or lengths. Different equipment needs to be changed for rewinding ton bags of different diameters and lengths, which will reduce the working efficiency of ton bag rewinding. To address this, we propose a ton bag rewinding machine. Utility Model Content

When the ton bag is rolled up, it avoids loosening and slippage during the winding process. It can flexibly adapt to winding rollers of different diameters or lengths. There is no need to change equipment. The winding rollers can be quickly replaced, improving the working efficiency of ton bag winding.

The inner end of the top block is fixedly connected to the support rod, and the inner end of the support rod is fixedly connected to the U-shaped block. Rollers are rotatably connected inside the U-shaped block. The inner wall of the rotating shaft is provided with evenly distributed slide grooves. An internally threaded cylinder is slidably connected between three slide grooves located on the same horizontal line. Evenly distributed trapezoidal blocks are fixedly connected to the outside of the internally threaded cylinder. The outer surface of the trapezoidal blocks is slidably connected to the outer surface of the vertically adjacent rollers to provide extrusion connection.

[0011] Furthermore, the winding roller fixing mechanism also includes springs, and springs are respectively sleeved on the outside of the support rod between the upper end of the U-shaped block and the lower end of the adjacent sliding groove to facilitate rebound.

[0012] Furthermore, the winding roller fixing mechanism also includes a drive assembly, which includes a lead screw, a worm gear, a worm, and a dial.

The roller pushes the top block outward through the U-shaped block and support rod, so that the top block presses and clamps the inner wall of the winding roller. When winding ton bags, this prevents the winding roller from becoming loose and slipping during the winding process.

[0017] 2. By rotating the sleeve, the sleeve will fix the baffle two and the pair of winding rollers of the baffle through the internal thread ring and the slip ring. Then, the locking bolts are rotated to insert into the corresponding holes. When winding ton bags, it can flexibly adapt to winding rollers of different diameters or lengths without changing the equipment. The winding rollers can be quickly replaced, improving the working efficiency of ton bag winding. Attached Figure Description

The worm gear 512 is fixedly sleeved on the outer wall of the rear end of the lead screw 511. The worm 513 is rotatably connected to the rear end of the inner wall of the rotating shaft 2. The worm gear 512 meshes with the worm 513. The dial 514 is fixedly connected to the left end of the worm 513. When winding the ton bag, the winding roller is first sleeved on the outside of the rotating shaft 2, and then the dial 514 is rotated to... The disc 514 will drive the worm 513 to rotate. The rotation of the worm 513 will drive the lead screw 511 to rotate through the meshing worm wheel 512. The rotation of the lead screw 511 will drive the internal threaded cylinder 58 to move backward between the three sliding grooves 59 located on the same horizontal line. This will then drive the trapezoidal block 57 to move backward, so that the inclined surface of the trapezoidal block 57 contacts the roller 56.

Then, the slip ring 62 is inserted into the front end of the rotating shaft 2, which causes the second baffle 4 to slide on the outer wall of the front end of the rotating shaft 2. Then, the rotating sleeve 64 drives the internal threaded ring 63 to move backward on the external thread of the screw 511. Then, the slip ring 62 causes the second baffle 4 to move backward, pushing the take-up roller backward, which fixes the take-up roller between the first baffle 3 and the second baffle 4. Then, the locking bolt 66 is rotated to insert the lower end of the locking bolt 66 into the corresponding insertion hole 65.

[0028] The working principle of the ton bag winding machine provided by this utility model is as follows: When winding the ton bag, the winding roller is first sleeved outside the rotating shaft 2. Then, the rotating dial 514 is rotated, which drives the worm 513 to rotate. The rotation of the worm 513 drives the lead screw 511 to rotate through the meshing worm wheel 512. The rotation of the lead screw 511 drives the internal threaded cylinder 58 to move backward between the three sliding grooves 59 located on the same horizontal line. This, in turn, drives the trapezoidal blocks 57 to move backward, so that the inclined surface of the trapezoidal blocks 57 contacts the roller 56. When the highest point of the trapezoidal block 57 contacts the roller 56, the top block 52 is pushed outward by the U-shaped block 55 and the support rod 53, so that the top block 52 engages the winding mechanism. The inner wall of the roller is pressurized and clamped. Then, the slip ring 62 is inserted into the front end of the rotating shaft 2, causing the second baffle 4 to slide on the outer wall of the front end of the rotating shaft 2. Then, the rotating sleeve 64 drives the internal threaded ring 63 to move backward on the external thread of the screw 511. Then, the slip ring 62 causes the second baffle 4 to move backward, pushing the winding roller backward, thus fixing the winding roller between the first baffle 3 and the second baffle 4. Then, the locking bolt 66 is rotated, causing the lower end of the locking bolt 66 to be inserted into the corresponding insertion hole 65. Then, the control switch 8 is adjusted, the motor 7 is operated, and the output shaft of the motor 7 drives the rotating shaft 2 to rotate. The rotation of the rotating shaft 2 drives the winding roller to wind up the ton bag.

[0029] It is worth noting that the motor 7 disclosed in the above embodiments can be Y180L-615, and the control switch 8 is provided with a switch button corresponding to the motor 7 and used to control its switching operation.
