Description

Technical Field

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

[0002] With the increasing global awareness of environmental protection and a deeper understanding of the pollution problems caused by traditional plastic bags, the market demand for biodegradable bags, as an environmentally friendly alternative, is growing rapidly. Biodegradable bags can gradually decompose in the natural environment through the action of microorganisms, effectively reducing the long-term pollution of soil, water and other ecological environments by plastic waste, which is in line with the strategic requirements of sustainable development.

[0003] However, existing biodegradable bag punching equipment is not convenient to change the cutter according to the required hole size. As a result, when facing different punching needs and needing to change to different types or specifications of cutters, a lot of time is often spent on changing the cutter, which greatly reduces the working efficiency of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a biodegradable bag punching device. By setting up a blade changing mechanism, it solves the problem that it is inconvenient to change the blade according to the size of the hole. As a result, when facing different punching needs, it is often necessary to change to different types or specifications of blades, which often requires a lot of time to change the blade, greatly reducing the working efficiency of the equipment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a biodegradable bag punching device, which includes two supports, and the two supports are equipped with a blade changing mechanism and two positioning mechanisms.

[0007] A transmission assembly is provided between the two supports. The tool changing mechanism includes a support frame fixedly connected to the two supports. An electric telescopic rod is fixedly connected to the support frame. A fixing ring is fixedly connected to the output shaft of the electric telescopic rod. The positioning mechanism includes a threaded rod threadedly connected to the support frame (211). A handle is fixedly connected to the side of the threaded rod away from the electric telescopic rod.

[0008] Furthermore, the fixing ring has several limiting grooves, and the outer wall of the fixing ring is fitted with a limiting ring.

[0009] Furthermore, a spring is sleeved on the outer wall of the fixing ring, the top of the spring is fixedly connected to the electric telescopic rod, the bottom of the spring is fixedly connected to the limiting ring, and a fixing plate is slidably connected to the outer wall of the fixing ring.

[0010] Furthermore, a number of limiting blocks are fixedly connected to the fixing plate, and the limiting blocks are respectively adapted to a number of limiting grooves. A cutter is fixedly connected to the bottom of the fixing plate.

[0011] Furthermore, two slide rods are slidably connected to the left side of the support frame, and the right sides of both slide rods extend into the support frame. An L-shaped plate is rotatably connected to the right side of the threaded rod, and both slide rods are fixedly connected to the L-shaped plate.

[0012] Furthermore, the L-shaped plate is provided with several sliding grooves, and each of the several sliding grooves is slidably connected with a sliding rod.

[0013] Furthermore, springs are fitted onto the outer walls of several slide rods, the tops of several springs are fixedly connected to several slide rods, the bottoms of several springs are fixedly connected to L-shaped plates, and pressure rollers are rotatably connected to the bottoms of slide rods, with the pressure rollers in contact with the conveying assembly.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a blade changing mechanism, the cutter can be replaced according to the required hole. When the original cutter is removed, the limiting ring is slid upward. When the limiting ring is slid upward, the spring is compressed. After the limiting ring is slid, it stops restricting the fixed plate, so the limiting block can be pulled out from the limiting groove on the fixed ring. The cutter can then be removed. At this time, the new cutter is put on the fixed ring. Then, the cutter is pushed upward. When the cutter is pushed, the limiting block will first contact the fixed ring. Then, the limiting block will be pushed apart by the side that is away from it. At this time, the fixed plate will be opened. Then, the cutter is pushed, and the limiting block will enter the limiting groove. At this time, the limiting ring is released. After the limiting ring is released, the spring will push it downward. The pushed limiting ring will restrict the fixed plate again. This achieves the replacement of the cutter. It is convenient to quickly change different types or specifications of cutters according to different drilling needs. Thus, the equipment can adapt to a variety of drilling tasks and improve the versatility and flexibility of the equipment.

[0016] 2. By setting a positioning mechanism, after changing the blade, adjust the distance between the L-shaped plates according to the size of the biodegradable bag. During adjustment, turn the handle; as the handle turns, the threaded rod will slide inward or outward, causing the L-shaped plates to slide accordingly. The sliding rod on the L-shaped plate will also slide on the support frame. The distance between the L-shaped plates can be adjusted by rotating the threaded rod. After adjustment, place the biodegradable bag on the conveyor assembly and then start the conveyor assembly. As the conveyor assembly runs, the biodegradable bag will reach under the pressure roller, where it will press against the biodegradable bag, thus accelerating the degradation process. After the bag is pressed, the pressure roller is pushed upwards due to its thickness. At this time, the second slide rod slides on the slide groove. As the second slide rod slides, the second spring is pulled. Thus, the elasticity of the second spring fixes the biodegradable bag in place. When the biodegradable bag reaches below the cutter, the electric telescopic rod is activated, causing it to move downwards and the cutter to cut the biodegradable bag. This allows the equipment to adapt to punching operations of biodegradable bags of various sizes, improving the equipment's versatility and applicability. It avoids the trouble of changing different equipment due to different biodegradable bag sizes and reduces production costs.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The top of the spring 216 is fixedly connected to the electric telescopic rod 212, and the bottom of the spring 216 is fixedly connected to the limiting ring 215. A fixed plate 217 is slidably connected to the outer wall of the fixed ring 213. Several limiting blocks 218 are fixedly connected to the fixed plate 217, and the limiting blocks 218 are respectively adapted to several limiting grooves 214. A cutter 219 is fixedly connected to the bottom of the fixed plate 217. Two slide rods 313 are slidably connected to the left side of the support frame 211. The right side of the two slide rods 313 extends into the support frame 211. An L-shaped plate 314 is rotatably connected to the right side of the threaded rod 311. The two slide rods 313 are fixedly connected to the L-shaped plate 314. By setting the cutter changing mechanism 2, it is easy to quickly change different types or specifications of cutters according to different drilling needs. Thus, the equipment can adapt to a variety of drilling tasks and improve the versatility and flexibility of the equipment.

[0029] The positioning mechanism 3 includes a threaded rod 311 threadedly connected to the support frame 211. A handle 312 is fixedly connected to the side of the threaded rod 311 away from the electric telescopic rod 212. Several sliding grooves 315 are provided on the L-shaped plate 314. Sliding rods 316 are slidably connected in each of the sliding grooves 315. Springs 317 are fitted on the outer walls of each sliding rod 316. The tops of the springs 317 are fixedly connected to the sliding rods 316, and the bottoms of the springs 317 are fixedly connected to the L-shaped plate 314.

[0030] A specific application of this embodiment is as follows: In use, first, replace the cutter 219 according to the required hole. When removing the original cutter 219, slide the limiting ring 215 upward. When the limiting ring 215 is slid upward, the spring 216 will be compressed. After the limiting ring 215 is slid, it will stop restricting the fixing plate 217. Thus, the limiting block 218 can be pulled out from the limiting groove 214 on the fixing ring 213, thereby removing the cutter 219. At this time, put the new cutter 219 on the fixing ring 213, and then push the cutter upward. When the cutter 219 is pushed, the limiting block 218 first contacts the fixing ring 213. Then, the limiting block 218 is pushed open by the side furthest away from it, thus opening the fixing plate 217. Next, the cutter 219 is pushed, and the limiting block 218 enters the limiting groove 214. At this point, the limiting ring 215 is released, and after it is released, the spring 216 pushes it downwards. The pushed-out limiting ring 215 then restricts the fixing plate 217 again, thus achieving the replacement of the cutter 219. After the cutter is replaced, the root... Adjust the distance between the L-shaped plates 314 according to the size of the biodegradable bag. To adjust, rotate the handle 312. As the handle 312 rotates, the threaded rod 311 slides inward or outward, causing the L-shaped plates 314 to slide accordingly. The sliding rod 313 on the L-shaped plates 314 also slides on the support frame 211. Rotating the threaded rod 311 adjusts the distance between the L-shaped plates 314. After adjustment, place the biodegradable bag on the conveyor assembly 101 and then start the conveyor assembly 101. While the conveyor assembly 101 is running, the biodegradable bags... The bag will then reach the pressure roller 318, where it will press the biodegradable bag. Due to the thickness of the bag, the pressure roller 318 will be pushed upwards. At this time, the slide bar 316 will slide on the slide groove 315. As the slide bar 316 slides, the spring 317 will be pulled, thus fixing the biodegradable bag in place through the elasticity of the spring 317. When the biodegradable bag reaches the cutter 219, the electric telescopic rod 212 will be activated, causing it to move downwards and the cutter 219 to cut the biodegradable bag.
