Description

Technical Field

[0001] The utility model relates to the technical field of woven bags, in particular to a woven bag opening device. Background Art

[0002] Plastic woven bags are mainly composed of polypropylene bags and polyethylene bags. They are divided into bottom-sewn bags and edge-sewn bottom bags according to the sewing method. They are currently widely used as a packaging material for fertilizers, chemical products and other items. The main production process is to use plastic raw materials to extrude films, cut, and unidirectionally stretch them into flat wires, and then weave them through warp and weft to get the products, which are generally called woven bags. In the bulk material filling industry, especially in the bulk material filling industries such as grain, oil, food, feed, cement, and chemicals, manufacturers take into account factors such as production costs, and the woven bags are soft and thin, so they often use low-priced woven bags to fill materials.

[0003] The Chinese utility model patent with patent application number 202320840480.7 provides a woven bag opening device. According to the size and model of the woven bag, the position of a set of fixed plates is adjusted by a first adjusting component, and according to the position of the woven bag, the position of the driven clamping structure is adjusted by a second adjusting component, so that the two sets of fixed clamps clamp and fix the two sides of the woven bag. After fixing, the turntable is rotated so that a set of first threaded sleeves move relative to the bidirectional threaded rod. The woven bag can be opened by cooperating with the connecting plate, the movable plate and the fixed plate, which is convenient for filling the material into the woven bag and makes the filling more efficient.

[0004] However, during the use of the above-mentioned equipment, it was found that when the equipment replaces different woven bags, it is necessary to adjust the positions of multiple spring clips to adapt to the clamping requirements of different woven bags. Multiple sets of threaded rods need to be rotated, and while rotating the threaded rods, it is necessary to pay attention to ensuring that the adjustments on the fixed plates on both sides are consistent. This makes the entire adjustment process more cumbersome, and the efficiency of stretching out different woven bags after replacement is low. Utility Model Content

[0022] Embodiment 1

[0023] See also Figure 1-Figure 6 The woven bag opening device shown in the figure includes a placing table 1, a rotating groove 13 is provided inside the placing table 1, a spreading component 6 is provided in the rotating groove 13, and the spreading component 6 includes a slider 65, and a clamping component 3 is fixedly installed on the top of the slider 65;

[0024] The expansion assembly 6 includes a rotating shaft 61, a worm 62 is mounted on the rotating shaft 61, the worm 62 is meshed with a worm wheel 63, a vortex slide 64 is provided on the worm wheel 63, and a slider 65 is slidably connected to the vortex slide 64;

[0025] The top of the placement table 1 is provided with a ring array of movable grooves 12, and the clamping assembly 3 is installed in the movable groove 12. The clamping assembly 3 includes a lifting rod 32, and one side of the top of the lifting rod 32 is connected to a fixing clamp 5;

[0026] The clamping assembly 3 includes a sleeve 31, a connecting groove 33 is provided at the bottom of the sleeve 31, the sleeve 31 is connected to the movable groove 12 through the connecting groove 33, a connecting pipe 36 is connected to one side of the sleeve 31, a limit rod 341 is slidably connected in the connecting pipe 36, and one end of the limit rod 341 is fixedly connected to the handle 34;

[0027] A spring 35 is arranged on the outer side of the connecting tube 36, and the spring 35 is connected to the handle 34, and the handle 34 is connected to the sleeve 31 through the spring 35. A connecting rod 321 is fixedly connected to the bottom of the lifting rod 32, and the lifting rod 32 is slidably connected in the sleeve 31 through the connecting rod 321. A limiting hole 322 is provided on the connecting rod 321, and the limiting hole 322 corresponds to the limiting rod 341;

[0028] The rotating shaft 61 in the supporting assembly 6 is connected to the connecting shaft 2, and a sliding groove 21 is provided on the connecting shaft 2. A fixed ring 4 is slidably connected in the sliding groove 21. A moving block 41 is provided in the fixed ring 4. The moving block 41 is provided in the sliding groove 21. An annular magnet 1 42 is provided in the fixed ring 4. The connecting shaft 2 is provided on one side of the placing table 1. An annular magnet 2 11 surrounds the circumference of the connecting shaft 2. The annular magnet 2 11 is installed on the placing table 1.

[0029] In this solution, before use, the clamping assembly 3 is in the middle of the placement table 1, the magnet 2 42 on the fixing ring 4 is magnetically connected to the magnet 1 11 on the placement table 1, and the staff clamps the woven bag with the fixing clamp 5. After the woven bag is clamped, the staff uses the opening assembly 6 to control the opening of the woven bag to unfold;

[0030] The staff pulls the fixing ring 4, so that the fixing ring 4 moves along the sliding groove 21 and separates the magnet 2 42 from the magnet 1 11, so that the staff can rotate the fixing ring 4 and drive the connecting shaft 2 to rotate. During the rotation of the connecting shaft 2, the connecting shaft 2 drives the rotating shaft 61 to rotate, thereby controlling the rotation of the worm 62 on the rotating shaft 61. The meshing of the worm 62 and the worm wheel 63 makes the worm wheel 63 rotate under the drive of the worm 62, so that the vortex slideway 64 on the worm wheel 63 rotates, and then the slider 65 on the vortex slideway 64 is affected by the sleeve 31 to move along the vortex slideway 64, and at the same time, the sleeve 31 moves along the moving groove 12. The sleeve 31 clamping the woven bag in different directions can simultaneously drive the bag mouth of the woven bag to unfold when moving. When facing different woven bags for installation, the complexity of equipment adjustment can be reduced, so that the equipment has higher efficiency in clamping and opening different woven bags.

[0031] After the woven bag is stretched out, the staff pushes the fixing ring 4 so that the second magnet 42 on the fixing ring 4 is magnetically connected with the first magnet 11, thereby using the magnetic connection to quickly fix the fixing ring 4. When fixing the fixing ring 4, it can avoid accidental contact that causes the connecting shaft 2 to rotate, thereby causing the worm 62 to rotate and the clamping assembly 3 to move, so that the woven bag is not fully unfolded.

[0032] When dealing with woven bags of different heights, the height of the clamping assembly 3 can be adjusted. When the clamping height of the clamping assembly 3 needs to be higher, the staff pulls the handle 34 so that the handle 34 pulls the spring 35 to extend, and at the same time, the limit rod 341 moves along the connecting tube 36 and moves out of the limit hole 322 to contact the restriction on the connecting rod 321, so that the connecting rod 321 can move along the sleeve 31 and extend. When the connecting rod 321 extends and the lifting rod 32 drives the fixing clamp 5 to move to a suitable height, the staff releases the handle 34, so that the handle 34 returns to its original state under the pull of the spring 35, and the limit rod 341 moves along the connecting tube 36 and enters the limit hole 322 to limit and fix the connecting rod 321, thereby realizing rapid fixation of the lifting rod 32. The height adjustment of the clamping assembly 3 makes the device more applicable to different woven bags.
