Abstract
Description
Technical Field
[0001] This utility model belongs to the field of raw material crushing technology, specifically relating to a modified polypropylene material raw material crushing and mixing machine. Background Technology
[0002] Modified polypropylene is a polymer material that improves the properties of virgin polypropylene through chemical or physical methods. This modified polypropylene has high strength and hardness, exhibits excellent wear resistance and impact resistance, and also has excellent thermal stability and high-temperature resistance. Modified polypropylene is widely used in the production of various products such as plastic bags, packaging films, automotive parts, and household appliance casings. When recycling and reusing modified polypropylene materials, waste plastics are usually crushed for secondary processing and manufacturing.
[0003] However, in actual use, existing crushing and mixing machines present some problems when processing waste plastic raw materials, especially modified polypropylene, because the surface of the raw materials has a large amount of debris and dust adhering to it during crushing. The debris and dust adhering to the surface of the raw materials will generate a lot of dust during the crushing process, which not only pollutes the environment, but may also cause the equipment to overheat due to prolonged use, and even melt the polypropylene. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a modified polypropylene material raw material crushing and mixing machine with the advantage of dust reduction.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a modified polypropylene material raw material crushing and mixing machine, comprising a crushing box, a bulletproof mechanism on the top of the crushing box, a fixed frame fixedly connected to the outside of the crushing box, a motor fixedly connected to the outside of the fixed frame, two correspondingly distributed rotating rods rotatably connected inside the crushing box, multiple correspondingly distributed cutters fixedly connected to the outside of each of the two rotating rods, two correspondingly distributed gears rotatably connected to the outside of the crushing box, the two gears meshing with each other, the two gears being fixedly connected to their respective rotating rods, the output end of the motor being fixedly connected to one of the gears, two baffles fixedly connected to the bottom of the crushing box, a dust suppression mechanism provided between the two baffles, and a water tank fixedly connected to the bottom of the two baffles.
[0006] Preferably, the dust suppression mechanism includes a feeding screen plate, which is fixedly connected between two baffles. A filter screen is fixedly connected inside the water tank, and a water pump is fixedly connected to the bottom of the water tank, with the input end of the water pump connected to the water tank.
[0007] Preferably, the output end of the water pump is connected to a water outlet pipe, and the outside of the water outlet pipe is connected to a plurality of correspondingly distributed spray pipes.
[0008] Preferably, each of the plurality of water spray pipes is externally connected to two symmetrically distributed atomizing nozzles, and the atomizing nozzles are inserted into the interior of the pulverizing chamber.
[0009] Preferably, the bulletproof mechanism includes a feeding box, which is fixedly connected to the top of the crushing box. A rotating column is rotatably connected inside the feeding box, and a bulletproof plate is fixedly connected to the outside of the rotating column.
[0010] Preferably, support columns are fixedly connected to the four corners of the bottom of the water tank, and two correspondingly distributed feeding inclined plates are fixedly connected inside the crushing box.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. When the raw materials are being crushed, the water pump is first started. Water is drawn from the water tank through the pump's input end and discharged into the outlet pipe through the pump's output end. The water then enters the spray pipe through the outlet pipe and is sprayed into the crushing chamber through the atomizing nozzle connected to the spray pipe. The atomization of the water wets the cutter on one of the rotating rods, preventing the cutter from overheating during prolonged operation and causing the polypropylene to melt. At the same time, the dust generated by the cutter during crushing is suppressed by the water spray from the atomizing nozzle. The crushed raw materials slide down to the designated position through the feed screen, while the water passes through the feed screen and enters the water tank. As the water comes into contact with the filter screen, the dust in the water is blocked by the filter screen. The water then enters the bottom of the water tank, thus achieving the effect of partial water recycling, saving water resources, and achieving the effect of dust suppression. Through the above mechanism, dust can be effectively suppressed during the crushing of raw materials, making the working environment better, and effectively preventing the equipment from overheating and melting the polypropylene.
[0013] 2. When raw materials need to be crushed, they are first put into the feed box. Then, the raw materials come into contact with the bulletproof plate and begin to be subjected to force. At this time, the rotating column starts to rotate, thereby driving the bulletproof plate to rotate. Then, the raw materials slide down and enter the interior of the crushing box, where they come into contact with the cutter for crushing. At this time, the bulletproof plate is no longer in contact with the raw materials. Due to the influence of gravity, it returns to its vertical position, which can effectively prevent the raw materials from being ejected from the crushing box during crushing. Through the above mechanism, it is possible to effectively prevent the raw materials from being ejected from the crushing box during crushing. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1:
[0021] Please see Figure 1-4 This utility model provides a technical solution: a modified polypropylene material raw material crushing and mixing machine, including a crushing box 1, a bulletproof mechanism 3 on the top of the crushing box 1, a fixed frame 4 fixedly connected to the outside of the crushing box 1, a motor 5 fixedly connected to the outside of the fixed frame 4, two correspondingly distributed rotating rods 9 rotatably connected inside the crushing box 1, multiple correspondingly distributed cutters 10 fixedly connected to the outside of each of the two rotating rods 9, two correspondingly distributed gears 6 rotatably connected to the outside of the crushing box 1, the two gears 6 meshing with each other, the two gears 6 being fixedly connected to their respective rotating rods 9, the output end of the motor 5 being fixedly connected to one of the gears 6, two baffles 7 fixedly connected to the bottom of the crushing box 1, a dust suppression mechanism 2 provided between the two baffles 7, and a water tank 8 fixedly connected to the bottom of the two baffles 7.
[0022] In this implementation scheme, when it is necessary to crush the raw materials, the motor 5 is started first. The output end of the motor 5 rotates, thereby driving one of the gears 6 to rotate. Since the two gears 6 mesh, the other gear 6 also rotates. Since the gear 6 and the rotating rod 9 are fixedly connected, the rotation of the gear 6 will drive the rotating rod 9 to rotate. The rotation of the rotating rod 9 will drive multiple cutters 10 to rotate. The rotation of the multiple cutters 10 will cut and crush the raw materials. The dust suppression mechanism 2 can suppress dust during the crushing of the raw materials, making the working environment better. At the same time, it can effectively prevent the equipment from overheating and melting polypropylene. The bulletproof mechanism 3 can effectively prevent the raw materials from being ejected from the crushing box 1 during crushing.
[0023] Example 2:
[0024] Please see Figure 1-4 Based on Embodiment 1, this utility model provides a technical solution: the dust suppression mechanism 2 includes a feeding screen 201, which is fixedly connected between two baffles 7. A filter screen 202 is fixedly connected inside the water tank 8. A water pump 203 is fixedly connected to the bottom of the water tank 8, and the input end of the water pump 203 is connected to the water tank 8. The output end of the water pump 203 is connected to a water outlet pipe 204. Multiple correspondingly distributed water spray pipes 205 are connected to the outside of the water outlet pipe 204. Two symmetrically distributed atomizing nozzles 206 are connected to the outside of each of the multiple water spray pipes 205. The atomizing nozzles 206 are inserted into the inside of the crushing box 1. Preferably, support columns 11 are fixedly connected to the four corners of the bottom of the water tank 8, and two correspondingly distributed feeding inclined plates 304 are fixedly connected inside the crushing box 1.
[0025] In this embodiment, when the raw material is being crushed, the water pump 203 is first started. Water is drawn from the water tank 8 through the input end of the water pump 203 and discharged into the outlet pipe 204 through the output end of the water pump 203. Then, the water enters the spray pipe 205 through the outlet pipe 204. Subsequently, the water is sprayed into the crushing chamber 1 through the atomizing nozzle 206 connected to the spray pipe 205. Through water atomization, the cutter 10 on one of the rotating rods 9 can be moistened to prevent the cutter 10 from generating high temperatures during long-term operation, which could cause the polypropylene to melt. At the same time, when the cutter 10 crushes the raw material, the generated... Dust can be suppressed by spraying water through the atomizing nozzle 206. The crushed raw materials slide down to the designated position through the feeding screen 201, while the water passes through the feeding screen 201 and enters the water tank 8. As the water comes into contact with the filter screen 202, the dust in the water is blocked by the filter screen 202. Then the water enters the bottom of the water tank 8, thus achieving the effect of recycling some of the water, thereby saving water resources and achieving the effect of dust suppression. Through the above mechanism, dust can be effectively suppressed during the crushing of raw materials, making the working environment better, and at the same time, it can effectively prevent the equipment from overheating and melting polypropylene.
[0026] Example 3:
[0027] Please see Figure 1-4 Based on Embodiment 1 and Embodiment 2, this utility model provides a technical solution: the bulletproof mechanism 3 includes a feeding box 301, the feeding box 301 is fixedly connected to the top of the crushing box 1, a rotating column 302 is rotatably connected inside the feeding box 301, and a bulletproof plate 303 is fixedly connected to the outside of the rotating column 302.
[0028] In this embodiment, when the raw material needs to be crushed, it is first put into the feed box 301. Then the raw material comes into contact with the bulletproof plate 303 and begins to be subjected to force. At this time, the rotating column 302 starts to rotate, thereby driving the bulletproof plate 303 to rotate. Then the raw material slides down and enters the interior of the crushing box 1, and comes into contact with the cutter 10 for crushing. At this time, the bulletproof plate 303 is no longer in contact with the raw material. Due to the influence of gravity, it returns to its vertical position again, which can effectively prevent the raw material from popping out of the crushing box 1 during crushing. Through the above mechanism, the raw material can be effectively prevented from popping out of the crushing box 1 during crushing.
[0029] The working principle and usage process of this utility model are as follows: When the raw materials are being crushed, the water pump 203 is first started. Water is drawn from the water tank 8 through the input end of the water pump 203 and discharged into the water outlet pipe 204 through the output end of the water pump 203. Then, the water enters the spray pipe 205 through the water outlet pipe 204. Subsequently, the water is sprayed into the crushing chamber 1 through the atomizing nozzle 206 connected to the spray pipe 205. Through water atomization, the cutter 10 on one of the rotating rods 9 can be moistened to prevent the cutter 10 from generating high temperature during long-term operation. This causes the polypropylene to melt. At the same time, when the cutter 10 is crushing the raw material, the dust generated can be sprayed with water through the atomizing nozzle 206 to suppress the dust. The crushed raw material slides down to the designated position through the feeding screen 201, while the water passes through the feeding screen 201 and enters the interior of the water tank 8. Whenever the water comes into contact with the filter screen 202, the dust in the water is blocked by the filter screen 202. Then the water enters the bottom of the water tank 8, thereby achieving the effect of recycling some of the water, thus saving water resources and achieving the effect of dust suppression.
[0030] When the raw material needs to be crushed, it is first put into the feed box 301. Then the raw material comes into contact with the bulletproof plate 303 and begins to be subjected to force. At this time, the rotating column 302 starts to rotate, thereby driving the bulletproof plate 303 to rotate. Then the raw material slides down and enters the interior of the crushing box 1, where it comes into contact with the cutter 10 for crushing. At this time, the bulletproof plate 303 is no longer in contact with the raw material. Due to the influence of gravity, it returns to its vertical position, which can effectively prevent the raw material from being ejected from the crushing box 1 during crushing.
