Description
Technical Field
[0001] This utility model relates to the field of crushing equipment technology, and in particular to a crushing equipment for engineering plastics that can thoroughly crush them. Background Technology
[0002] Crushing equipment is an industrial machine that uses mechanical force to break large materials into smaller pieces. It is widely used in mining, chemical, building materials, metallurgy, food, and pharmaceutical industries. There are various types, with common types including jaw crushers, hammer crushers, cone crushers, impact crushers, and roller crushers. Different equipment has different working principles, applicable materials, and crushing particle size ranges. The appropriate type can be selected based on the material properties, production scale, and finished product particle size requirements. Its core function is to reduce material particle size to meet the needs of subsequent processing, application, and environmental treatment, while simultaneously improving material utilization and processing efficiency.
[0003] Currently, hammer crushers are used to crush engineering plastics. During the crushing process, due to the different impacts and degrees of crushing on the materials, the particle size distribution of the product is uneven. Some materials may be overcrushed, while others fail to meet the ideal particle size requirements. Existing technology uses a secondary crushing device near the discharge port of the crusher to further crush the material after the initial crushing, thereby reducing the particle size and improving the uniformity of the product particle size. However, secondary crushing can lead to over-crushing of the plastics and increase operating costs. Utility Model Content

[0032] 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.
[0033] Reference Figure 3 , Figure 4 and Figure 5 This utility model provides an embodiment of an engineering plastic pulverizing device that thoroughly pulverizes plastics, comprising a machine tool 1. A fixed frame 3 15 is fixedly connected to the middle of the right side of the inner wall of the machine tool 1. Limiting blocks 16 are fixedly connected to the upper and lower ends of the middle of the fixed frame 3 15. A rack 17 is rotatably connected to the front end of the limiting block 16. A top plate 23 is fixedly connected to the top of the rack 17. A motor 22 is fixedly connected to the front side of the middle of the fixed frame 3 15. A drive shaft 20 is fixedly connected to the output end of the motor 22. A driven gear 24 is fixedly connected to the middle of the drive shaft 20. The rear end of the drive shaft 20 is rotatably connected to the middle of the fixed frame 3 15. Limiting shafts 19 are rotatably connected to the left and right sides of the middle of the fixed frame 3 15. The middle of the limiting shafts 19 is fixedly connected to the middle of the fixed frame 3 15. A drive gear 21 is fixedly connected to the machine tool 1. The left and right sides of the driven gear 24 are meshed with the drive gear 21. A half gear 18 is fixedly connected to the rear end of the limiting shaft 19. The left and right sides of the rack 17 are meshed with the half gear 18. A sieve plate 25 is fixedly installed in the middle right side of the inner wall of the machine tool 1. A cleaning mechanism 2 is fixedly connected to the lower middle right side of the inner wall of the machine tool 1. The cleaning mechanism 2 is used to clean debris. A support frame 9 is fixedly connected to the top left side of the outer wall of the machine tool 1. A load-bearing plate 10 is fixedly connected to the top left and right sides of the support frame 9 to support the electric pump. Multiple screws 11 are threaded at equal intervals in the upper middle right side of the outer wall of the machine tool 1. A danger warning sign 12 is threaded on the outer side of the screws 11 to serve as a warning when the machine is running.
[0034] Specifically, by turning on motor 22, the top plate 23 at the top of the rack 17 drives the screen plate 25 to move up and down continuously. When motor 22 starts, the driving gear 21 at the rear drives the two driven gears 24 to rotate, thereby causing the two half gears 18 to rotate. The support frame 9 is fixedly connected to the top left of the outer wall of the machine tool 1, and the load-bearing plates 10 are fixedly installed on the top left and right sides of the frame to support the electric pump. Multiple screws 11 are fixedly connected to the upper right side of the outer wall of the machine tool 1 by equidistant threads. Each screw 11 is fitted with a danger warning sign 12 by threaded connection on the outside. This warning structure can effectively play a safety warning function during machine operation. The half gears 18 are connected to the rack 17, so the rack 17 will move up and down, thereby causing the screen plate 25 to move up and down. This allows the fragments that do not meet the requirements to return to the crushing chamber for crushing, solving the problem that secondary crushing will lead to excessive crushing of plastic and increase operating costs.
[0035] Reference Figure 1 , Figure 6 and Figure 7 The cleaning mechanism 2 includes a fixed frame 201, which is installed on the lower right side of the inner wall of the machine tool 1. A connecting shaft 202 is rotatably connected to both the left and right ends of the fixed frame 201. A fixed frame 203 is fixedly connected to the front right end of the fixed frame 201. A motor 205 is fixedly connected to the top front of the fixed frame 203. A transmission shaft 206 is rotatably connected to the top of the fixed frame 203. The output end of the motor 205 is fixedly connected to the front end of the transmission shaft 206. A bevel gear 207 is fixedly connected to the rear end of the transmission shaft 206. A bevel gear 204 meshes with the bottom of the bevel gear 207. The bottom of the bevel gear 204 is connected to the connecting shaft 202. The top of the machine tool 1 is fixedly connected to the bottom of the connecting shaft 1 202, and a sprocket 209 is fixedly connected to the bottom of the connecting shaft 1 202. A chain 208 is meshed with the outer side of the sprocket 209. A connecting shaft 212 is fixedly connected to the bottom of the chain 208. A brush 210 is fixedly connected to the bottom of the connecting shaft 212. A slide 211 is slidably connected to the bottom of the fixed frame 1 201. The bottom of the slide 211 is slidably connected to the connecting shaft 212. A block 3 is fixedly connected to the bottom left of the machine tool 1. A hook 4 is fixedly connected to the bottom of the block 3 for easy hanging of items by the user. Multiple load-bearing blocks 5 are fixedly connected at equal intervals to the bottom of the machine tool 1. Foot pads 6 are fixedly connected to the bottom of the load-bearing blocks 5 to reduce the impact of the machine tool 1 on the ground.
[0036] Specifically, by turning on motor 205, brush 210 rotates along chain 208 to clean machine tool 1. A block 3 is securely mounted on the bottom left side of machine tool 1. This connection method ensures that block 3 remains stable during machine tool 1 operation, preventing shaking or detachment. Hooks 4 are also mounted on the bottom of block 3 in the same manner. Users can hang frequently used items on hooks 4 according to their needs. This not only saves workspace and makes the operating environment cleaner and more organized, but also allows for quick retrieval of items when needed, effectively improving work efficiency. When motor 205 turns on and bevel gear 207 rotates, it drives the sprocket 209 below bevel gear 204 to rotate, thereby causing connecting shaft 212 on chain 208 to move synchronously with chain 208. This allows the brush 210 to rotate along the track of the chain 208, thereby achieving the cleaning purpose. This solves the problem that long-term accumulation of waste will harden or stick into clumps, requiring the use of high-pressure water guns, chisels, and other tools for cleaning, extending the cleaning time from thirty minutes to more than two hours and increasing labor costs. At the bottom of the machine tool 1, multiple load-bearing blocks 5 are arranged in an orderly manner at equal intervals and are firmly attached by a stable fixed connection. Under each load-bearing block 5, foot pads 6 are tightly fixed. These foot pads 6 are made of a special material with cushioning properties. Working together with the load-bearing blocks 5, they can effectively disperse the strong pressure generated by the machine tool 1 during operation, greatly reducing the impact force of the machine tool 1 on the ground. This not only protects the ground facilities from damage but also reduces the noise caused by the vibration of the machine tool 1, creating a better environment for stable equipment operation and operators.
[0037] Reference Figure 1 and Figure 2 A storage box 7 is slidably connected to the lower right side of the machine tool 1. A spherical pull block 8 is fixedly connected to the front side of the storage box 7, which can be used to store items. A limit ring 13 is fixedly connected to the middle right side of the outer wall of the machine tool 1. A magnetic block 14 is fixedly connected to the middle of the limit ring 13, which can attract small magnetic parts.
[0038] Specifically, a storage box 7 is embedded in the lower right side of the machine tool 1, which can be smoothly pushed in or pulled out along the track. A spherical pull block 8 is firmly fixed to its front side. Its rounded shape makes it easy to grip and apply force, effectively preventing scratches to the hands during frequent use. It provides a dedicated storage space, making the items needed for work readily accessible, greatly improving the convenience and efficiency of work. A limiting ring 13 is firmly fixed in the middle right side of the outer wall of the machine tool 1. A high-performance magnetic block 14 is embedded in the middle of the ring. The magnetic block 14 is made of high-quality magnetic material and has a strong adsorption force. It can firmly adsorb various small magnetic parts. When small parts such as nuts need to be temporarily placed, they can be quickly attracted and fixed by simply bringing them close to the magnetic block 14. This not only prevents the parts from slipping and being lost, but also makes them easy to retrieve at any time, making the workflow smoother and more efficient, and effectively improving the convenience and safety of the machine tool 1 during operation.
[0039] Working principle: By turning on the second motor 22, the top plate 23 at the top of the rack 17 drives the screen plate 25 to move up and down continuously. When the second motor 22 starts, the driving gear 21 at the rear will drive the two driven gears 24 to rotate, thereby causing the two half gears 18 to rotate. Since the half gears 18 are connected to the rack 17, the rack 17 will move up and down, thereby causing the screen plate 25 to move up and down. This allows the fragments that do not meet the requirements to return to the crushing chamber for crushing, thus solving the problem that secondary crushing will lead to over-crushing of plastic and increase operating costs.
[0040] By turning on motor 205, the brush 210 rotates along the track of chain 208 to clean the machine tool 1. When motor 205 turns on, the bevel gear 207 rotates, which drives the sprocket 209 below the bevel gear 204 to rotate. This causes the connecting shaft 212 on chain 208 to move synchronously with chain 208, thus causing the brush 210 to rotate along the track of chain 208 to achieve the cleaning purpose. This solves the problem that long-term accumulation of waste will harden or stick into clumps, requiring cleaning with tools such as high-pressure water guns and chisels, extending the cleaning time from thirty minutes to more than two hours, and increasing labor costs.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
