Description

Technical Field

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

[0002] With the increasing global awareness of environmental protection, the market demand for biodegradable bags as a substitute for traditional plastic bags has exploded. The cutting process, as the core link in the production of biodegradable bags, directly determines the dimensional accuracy and appearance quality of the product.

[0003] However, existing cutting devices for biodegradable bag processing are not convenient for fixing the biodegradable bags during cutting. The biodegradable bags are easily pushed off course by the cutting force during cutting, resulting in skewed cuts or dimensional deviations. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting device for processing biodegradable bags. By setting a fixed cutting mechanism, it solves the problem that existing cutting devices for processing biodegradable bags are not convenient to fix the biodegradable bags being processed during cutting, and that the biodegradable bags are easily pushed off course by the cutting force during cutting, resulting in skewed cuts or dimensional deviations.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a cutting device for processing biodegradable bags, including two support legs, on which a fixed cutting mechanism and several buffer mechanisms are provided; The fixed cutting mechanism includes a clamping assembly and a shearing assembly. The clamping assembly includes a fixing block 1 fixedly connected to the inner wall of the front support leg. A rotating shaft passes through the fixing block 1. Two gears are rotatably connected to the outer wall of the rotating shaft. Perforated support blocks are fixedly connected to the inner walls of both support legs. Racks 1 are slidably connected to the inner walls of both perforated support blocks. The two racks 1 mesh with the two gears respectively. The buffer mechanism includes a fixing block 2 disposed above the two support legs.

[0006] Furthermore, two racks are provided between the two support legs, and the two racks mesh with the two gears respectively. A motor is fixedly connected to the front of the fixing block, and the output shaft of the motor is fixedly connected to the rotating shaft through a coupling. The shearing assembly includes L-shaped support blocks that are fixedly connected to the top of the two support legs, and slide rods are fixedly connected to the inner walls of the two L-shaped support blocks.

[0007] Furthermore, a rectangular plate is slidably connected to the outer wall of each of the two slide rods, and the bottom of the rectangular plate is fixedly connected to two racks. A rectangular plate is slidably connected to the outer wall of each of the two slide rods, and both racks penetrate the rectangular plate. Both racks are slidably connected to the rectangular plate, and the bottom of the rectangular plate is fixedly connected to the two racks.

[0008] Furthermore, two clamping plates are provided between the first rectangular plate and the second rectangular plate. A cutting blade is provided at the bottom of the first rectangular plate, and a rectangular groove is provided on the upper clamping plate.

[0009] Furthermore, two transmission components are provided between the two support legs, and two guide blocks are fixedly connected to the top of each of the two support legs.

[0010] Furthermore, the tops of both fixed blocks 2 are fixedly connected to the rectangular plate 1, and a sliding rod 2 is fixedly connected between the two fixed blocks 2. Two sliders are slidably connected to the outer wall of the sliding rod 2.

[0011] Furthermore, the outer wall of the buffer mechanism of the slide bar two is fitted with two springs. The two springs are respectively fixedly connected to two fixed blocks two on their opposite sides. The two fixed blocks two are respectively fixedly connected to two sliders on their opposite sides. The bottom of each slider is hinged with a hinge rod. The bottom of each hinge rod is hinged with a hinge block. The bottom of the hinge block is fixedly connected to the clamping plate.

[0012] This utility model has the following beneficial effects: 1. By setting up a fixed cutting mechanism, the biodegradable bag to be processed is placed between two clamping plates and onto two conveying components. The two conveying components are then simultaneously activated, causing the biodegradable bag to move to the right. Under the action of the guide block, the bag descends and passes through the fixed cutting mechanism along a predetermined trajectory. After traveling a suitable distance, the two conveying components are stopped, and the motor is activated. The motor drives two gears to rotate via a shaft. These gears drive two racks (two pinions) to descend while simultaneously driving two racks (two pinions) to rise. This causes two racks (two pinions) to descend and two racks (two pinions) to rise, thus causing rectangular plate (one plate) to descend and vice versa. Rectangular plates (one plate) and (two pinions) pass through the fixed cutting mechanism on their respective surfaces. The buffer mechanism drives the two clamping plates to move closer together, thereby clamping the biodegradable bag between the two clamping plates. The two clamping plates continue to move closer until the cutting blade cuts the biodegradable bag through the rectangular groove. Then, the motor can be controlled to reverse, driving rectangular plate one and rectangular plate two to reset through the reverse process. At this time, the two clamping plates will also release the biodegradable bag. The two conveying components can be started to begin the next cut. At the same time, the cut biodegradable bag will also be conveyed out through the conveying component on the right side, so that the biodegradable bag remains stable during cutting, ensuring that the cutting blade cuts along the predetermined path, thereby obtaining a flat and smooth cut and avoiding skewed cuts or dimensional deviations. 2. By setting up a buffer mechanism, when the two clamping plates are in contact with the biodegradable bag and rectangular plates one and two are still close to each other, the buffer mechanism is analyzed. The other force conditions are similar. After the two clamping plates contact the biodegradable bag, they can no longer get close to each other. As a result, the hinge block is squeezed by the clamping plate it is on. The hinge block transmits the force to the two sliders through the hinge block, causing the two sliders to move away from each other. At this time, the two hinge blocks will also rotate around their hinge axis on the hinge block. At the same time, the spring will also contract and generate elastic force feedback to the two sliders. The two sliders feed back the force to the clamping plates through the hinge rod and the hinge block, so that the two clamping plates generate clamping force on the biodegradable bag between them, thereby completing the fixation of the biodegradable bag. During clamping, it can avoid damage such as clamping marks and breakage to the biodegradable bag due to excessive clamping force, ensuring the integrity and appearance quality of the biodegradable bag, and preventing the increase in product defect rate due to clamping damage.

The inner walls of both L-shaped support blocks 221 are fixedly connected to slide rods 222. The outer walls of the two slide rods 222 are slidably connected to rectangular plates 223. The bottom of rectangular plates 223 is fixedly connected to two racks 216. The outer walls of both slide rods 222 are slidably connected to rectangular plates 224. Both racks 216 penetrate rectangular plates 224 and are slidably connected to them. The bottom of rectangular plates 224 is fixedly connected to two racks 215. Rectangular plates 223 and rectangular plates 224... Two clamping plates 225 are arranged between the two rectangular plates 224. A cutting blade 226 is provided at the bottom of the rectangular plate 223. A rectangular groove 227 is opened on the clamping plate 225 located above. Two conveying components 111 are arranged between the two support legs 1. Two guide blocks 112 are fixedly connected to the top of the two support legs 1. By setting the fixed cutting mechanism 2, the biodegradable bag is kept stable during cutting, ensuring that the cutting blade 226 cuts along the predetermined path, thereby obtaining a flat and smooth cut and avoiding skewed cuts or dimensional deviations.

[0019] The buffer mechanism 3 includes two fixed blocks 311 positioned above the two support legs 1. The tops of the two fixed blocks 311 are fixedly connected to the rectangular plate 223. A sliding rod 312 is fixedly connected between the two fixed blocks 311. Two sliders 313 are slidably connected to the outer wall of the sliding rod 312. Two springs 314 are sleeved on the outer wall of the buffer mechanism 3 of the sliding rod 312.

[0020] A specific application of this embodiment is as follows: In use, the biodegradable bag to be processed is first placed between the two clamps 225 and onto the two conveying components 111. Then, the two conveying components 111 are opened simultaneously, causing the biodegradable bag to move to the right. Under the action of the guide block 112, the bag descends and passes through the fixed cutting mechanism 2 along a predetermined trajectory. After passing a suitable distance, the two conveying components 111 are stopped, and the motor 217 is turned on. The motor 217 drives the two gears 213 to rotate through the rotating shaft 212. The two gears 213 drive the two... As rack 216 descends, it drives racks 215 to rise. This causes racks 216 to lower rectangular plate 223, and racks 215 to raise rectangular plate 224. Rectangular plates 223 and 224, via buffer mechanisms 3, bring clamping plates 225 closer together, thus gripping the biodegradable bag between them. The clamping plates 225 continue to move closer until the cutting blade 226 cuts the biodegradable bag through the rectangular groove 227. Then, motor 217 can be reversed to rotate in the opposite direction. The reverse process causes rectangular plates 223 and 224 to reset. At this time, the two clamping plates 225 will also release the degradation bag. The two conveying components 111 can be activated to start the next cut. At the same time, the cut degradation bag will also be conveyed out through the conveying component 111 on the right. When the two clamping plates 225 are in contact with the degradation bag and rectangular plates 223 and 224 are still close to each other, the buffer mechanism 3 is analyzed. The other force conditions are similar. After the two clamping plates 225 contact the degradation bag, they can no longer get close to each other, thus hinged. Block 316 is squeezed by the clamping plate 225 on which it is located. The hinge block 316 transmits the force to the two sliders 313 through the hinge block 316, causing the two sliders 313 to move away from each other. At this time, the two hinge blocks 316 will also rotate around their hinge axis on the hinge block 316. At the same time, the spring 314 will also contract to generate elastic force feedback to the two sliders 313. The two sliders 313 feed back the force to the clamping plate 225 through the hinge rod 315 and the hinge block 316, so that the two clamping plates 225 generate clamping force on the degradation bag between them, thereby completing the fixation of the degradation bag.
