Description

Technical Field

[0001] The utility model belongs to the technical field of woven bag production, and particularly relates to a cutting device for woven bags. Background Technique

[0002] A woven bag, also known as a snake skin bag, is a type of plastic bag used for packaging. Its raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. The weaving density refers to the number of warp and weft yarns within a 100mm×100mm woven fabric. The production process includes processes such as wire drawing, weaving, printing, cutting, and bottom sewing. Woven bag cutting is a common operation in both industrial and manual fields. Existing woven bag cutting equipment basically uses blades or electric heating cutting wires to complete the cutting of woven bags. Compared with blade cutting, electric heating cutting wires do not need to be frequently replaced, reducing the problem of burrs on woven bags. However, when using electric heating cutting wires to cut a large number of woven bags, some volatile organic compounds (VOCs) and toxic polluting gases will be generated, causing certain harm to the environment and human health.

[0003] After retrieval, in a Chinese patent document (authorized announcement number CN216610283U), the utility model discloses a cutting device for woven bags, including a conveyor belt body and a placement rack. At the top of one end of the conveyor belt body close to the placement rack, there is a pressure roller that cooperates with the conveyor belt body. At the other end, there is an L-shaped rod. At the end of the L-shaped rod away from the conveyor belt body, there is a cylinder. The output end of the cylinder is provided with an electric heating cutting wire. On the conveyor belt body, there is a guide plate that cooperates with the electric heating cutting wire. On the placement rack, there is a woven bag roll around which a woven bag is wound. On the conveyor belt body, there is a controller that is electrically connected to the conveyor belt body, the cylinder, and the electric heating cutting wire respectively. The advantages of the utility model are: low production cost and high work efficiency, and can quickly cut woven bags. However, when using electric heating cutting wires to cut a large number of woven bags, some volatile organic compounds (VOCs) and toxic polluting gases will be generated, causing certain harm to the environment and human health.

The conveyor belt 1 is composed of components such as a conveyor belt, a driving device, rollers, idlers, a tensioning device, and a frame. The conveyor belt 1 of this woven bag cutting device is prior art, similar to (Zhengde plate chain conveyor) a conveyor belt conveyor. The conveyor belt of the conveyor belt 1 of this woven bag cutting device is made of metal or high-temperature resistant material to avoid damage or influence on the conveyor belt 1 when the electrothermal cutting wire 206 cuts. The moving part of the conveyor belt 1 described in this device is the part where the conveyor belt moves driven by two driving devices in the conveyor belt 1. The fixed part of the conveyor belt 1 described in this device is the frame part in the conveyor belt 1. Above the moving part of the conveyor belt 1, there is a filter box 3. On the side of the filter box 3, there is a second motor 309 installed. The output shaft of the second motor 309 is connected to a rotating shaft 306. On the outer circumference of the rotating shaft 306, there is a filter element 305. On the outer circumference of the filter element 305, there is a retaining ring 304 to prevent the filter element 305 from being misaligned when rotating. The retaining ring 304 has a strip-shaped outlet to facilitate the removal of the filter element 305. On the side of the filter box 3, two air outlet pipes 302 are symmetrically installed. The ends of the two air outlet pipes 302 are connected to an air suction fan 301. On the top of the filter box 3, there is an inlet 303. On the bottom of the filter box 3, there is an outlet 307. During operation, the inlet 303 and the outlet 307 are in a closed state. When the filter element 305 needs to be replaced, the inlet 303 is opened, and the filter element 305 can be taken out. On the side of the filter box 3, there is an air inlet 308. The air inlet 308 is strip-shaped and is located near the cutting position to facilitate the inhalation of the polluted gas generated during cutting. During operation, the air suction fan 301 and the second motor 309 are turned on. The polluted gas generated during cutting will enter from the air inlet 308, pass through the filter element 305, and finally be discharged through the air outlet pipe 302. The second motor 309 drives the rotating shaft 306 to rotate slowly, so that the gas fully contacts the filter element 305. Above the moving part of the conveyor belt 1, there is a cutting mechanism 2 for cutting the woven bag;

[0029] The cutting mechanism 2 includes two first support blocks 201. A connecting column 202 is connected to the tops of the two first support blocks 201. A first motor 205 is installed at the top of the connecting column 202. The output shaft of the first motor 205 is connected to a connecting rod 203.

[0032] Working principle

[0033] When using this cutting device for woven bags, first start the conveyor belt 1, and pass the woven bag to be cut through between the conveyor belt 1 and the third roller 7. The woven bag passes through multiple groups of fourth rollers 11 in sequence. The first motor 205 drives the first roller 204 to rotate, and the electric heating cutting wire 206 on the first roller 204 rotates accordingly to cut the passing woven bag. During cutting, the electric heating cutting wire 206 squeezes the first support column 210 towards the center of the first roller 204, and the first support column 210 squeezes the first spring 208. When the electric heating cutting wire 206 reaches the lowest point, the contact 211 contacts the receiver 212, and the receiver 212 records the number of times of contact with the contact 211, so that the number of cut woven bags can be obtained. After cutting, the anti-slip pad 207 pushes the uncut woven bag forward. Start the suction fan 301 and the second motor 309. The polluted gas generated during cutting enters from the air inlet 308, passes through the filter element 305, and finally is discharged through the air outlet pipe 302. The second motor 309 drives the rotating shaft 306 to rotate slowly, so that the gas is in full contact with the filter element 305. When the filter element 305 needs to be replaced, open the inlet 303, and the filter element 305 can be taken out. Start the third motor 401, and the third motor 401 drives the second roller 403 to rotate. The scraper 410 on the second roller 403 cleans the small amount of attachments generated by cutting remaining on the conveyor belt 1 through the baffle 404. The special-shaped block 407 on the second base 406 presses against the second spring 408, so that the scraper 410 is in full contact with the conveyor belt 1 for more thorough cleaning.
