[0002] With the acceleration of the industrialization and urbanization processes, the demand for packaging materials by people has gradually increased. As a lightweight and durable packaging material, plastic woven bags have gradually replaced traditional paper bags, cloth bags and other materials, meeting the market's demand for packaging materials. With the increase in market demand, the traditional manual cutting method can no longer meet the needs of large-scale production. Introducing a cutting device can achieve automatic cutting, greatly improving production efficiency and meeting the market's demand for mass production of products. The emergence of the cutting device for plastic woven bags in production is mainly to meet various needs such as improving production efficiency, reducing costs, improving product quality, responding to market demand and adapting to the trend of automation. These needs have prompted enterprises to continuously introduce innovative technologies and equipment to enhance competitiveness and adapt to market changes.
[0003] However, the existing cutting devices for plastic woven bags in production have the following problems: The traditional cutting devices for plastic woven bags in production cannot be adjusted according to the width of the bags. Each time the width of the bags is changed, the cutting device needs to be stopped for adjustment, which will significantly affect production efficiency, increase the production cycle and reduce production capacity. At the same time, different types of plastic woven bags have different thicknesses, and the cutting knife cannot adjust the cutting cross-section and cannot meet the cutting needs of woven bags with different thicknesses, resulting in poor cutting quality or damage to the woven bags.

[0025] Please refer to Figures 1-4 , an embodiment provided by the present utility model: a cutting device for plastic woven bags, including a main body frame 1 and a cutting mechanism 3 for plastic woven bags. A footrest 2 is installed at the bottom end of the main body frame 1, and a cutting mechanism 3 for plastic woven bags is arranged at the top end of the main body frame 1. A moving groove 301 is opened at the left side of the top end of the main body frame 1, and a sliding groove 302 is opened at the left side inside the moving groove 301.
[0026] Specifically, a slider 303 is connected to the right end card slot of the sliding groove 302, and a first telescopic rod 304 is connected to the right end card slot of the slider 303. The length of the first telescopic rod 304 is adjusted according to the width of the plastic woven bag, and the plastic woven bag is placed on the top end of the first telescopic rod 304 that has been adjusted.
[0027] Specifically, a fixing frame 305 is welded above the right end of the slider 303. A second telescopic rod 306 is connected to the bottom end card slot of the fixing frame 305. There are multiple groups of the second telescopic rods 306. The second telescopic rods 306 at the bottom end of the fixing frame 305 move telescopically downward to generate pressure, stably fixing the plastic woven bag on the surface of the first telescopic rod 304. At the same time, the number of the multiple groups of second telescopic rods 306 can be determined according to the length of the first telescopic rod 304.
[0028] Specifically, an anti-slip pressing disc 307 is threadedly connected to the bottom end of the second telescopic rod 306. The anti-slip pressing disc 307 is made of rubber. The second telescopic rod 306 moves telescopically to drive the anti-slip pressing disc 307 to move downward, squeezing the plastic woven bag. At the same time, the rubber anti-slip pressing disc 307 increases the contact area with the plastic woven bag, so that the plastic woven bag will not slide or fall off due to cutting.
[0029] Specifically, a first motor 308 is screwed to the rear side of the left end inside the moving groove 301. A first rotating rod 309 is connected to the left end card slot of the first motor 308. A rotating shaft 310 is threadedly connected to the front side of the left end inside the moving groove 301. A transmission belt 311 is sleeved on the outer sides of the first rotating rod 309 and the rotating shaft 310. The first motor 308 drives the first rotating rod 309 to rotate, and the first rotating rod 309 drives the transmission belt 311 to move forward, so that the transmission belt 311 automatically circulates. The rotating shaft 310 increases the stability of the transmission belt 311.
[0030] Specifically, a clamping member 312 is movably connected to the surface of the conveyor belt 311. The clamping member 312 is connected to the slider 303 by a card slot. As the conveyor belt 311 moves forward, it is fixed to the slider 303 through the clamping member 312. The conveyor belt 311 drives the slider 303 to move forward. After fixing the plastic woven bag, it drives the plastic woven bag to move forward for cutting. After the cutting is completed, the conveyor belt 311 drives the slider 303 to move backward to return to its original position.
[0031] Specifically, a support arm 313 is welded to the right end of the main body frame 1. A third telescopic rod 314 is connected to the inner right end of the support arm 313 by a card slot. The right end of the third telescopic rod 314 is movably connected to a connecting block 315. The bottom end of the connecting block 315 is connected to a fourth telescopic rod 316 by a card slot. The bottom end of the fourth telescopic rod 316 is connected to a second motor 317 by a card slot. The telescopic movement of the third telescopic rod 314 drives the connecting block 315 to adjust the horizontal position of cutting the plastic woven bag. The fourth telescopic rod 316 drives the second motor 317 to move downward telescopically to cut the plastic woven bag, and the cutting can be carried out according to the different thicknesses of the plastic woven bags.
[0032] Specifically, a second rotating rod 318 is connected to the front end of the second motor 317 by a card slot. A cutting blade 319 is connected to the outer side of the second rotating rod 318 by a card slot. A cutting groove 320 is arranged below the cutting blade 319. The second motor 317 drives the second rotating rod 318, and the second rotating rod 318 drives the cutting blade 319 to rotate for cutting. At the same time, the cutting blade 319 and the second rotating rod 318 are connected by a card slot and are easy to disassemble and replace. The cutting groove 320 fixes the position of the cutting blade 319 to prevent cutting errors in position.
[0033] Working principle: First, when in use, adjust the length of the first telescopic rod 304 according to the width of the plastic woven bag. Place the plastic woven bag on the top of the adjusted first telescopic rod 304. The second telescopic rod 306 at the bottom of the fixing frame 305 moves telescopically, driving the anti-slip pressing disc 307 to move downward to squeeze the plastic woven bag. At the same time, the anti-slip pressing disc 307 made of rubber increases the contact area with the plastic woven bag, so that the plastic woven bag will not slide or fall off due to cutting. At the same time, the number of groups of the second telescopic rods 306 can be determined according to the length of the first telescopic rod 304. The first motor 308 drives the first rotating rod 309 to rotate, and the first rotating rod 309 drives the conveyor belt 311 to move forward, so that the conveyor belt 311 automatically circulates. The conveyor belt 311 drives the slider 303 to move forward, driving the plastic woven bag to move forward for cutting. The third telescopic rod 314 moves telescopically to drive the connecting block 315 to adjust the horizontal position of cutting the plastic woven bag. The fourth telescopic rod 316 drives the second motor 317 to move downward, and the second motor 317 drives the second rotating rod 318 and the cutting blade 319 to rotate for cutting. The cutting groove 320 fixes the position of the cutting blade 319. After cutting, the conveyor belt 311 drives the slider 303 to move backward to return to the original position.
