Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to a plastic grinding mill equipped with a quantitative feeding and anti-clogging mechanism. Background Technology

[0002] With the rapid development of the plastics industry, the amount of plastic waste is also increasing day by day. In order to achieve sustainable use of resources and protection of the environment, the plastic recycling and reprocessing industry has gradually emerged. Plastic is a high molecular compound made by polymerization of monomers as raw materials through addition or condensation reactions. It has the ability to resist deformation and is between fiber and rubber. It is usually composed of synthetic resin, filler, plasticizer, etc. In the existing plastics processing industry, a large amount of plastic waste is generated. This waste usually needs to be crushed and processed before it can be reused. Plastic grinding mill is one of the key pieces of equipment in plastic recycling and processing. In the process of plastic recycling and processing, plastic or waste plastic needs to be ground. When using a grinding mill, plastic is usually put into the hopper. However, due to the accumulation of plastic, it will get stuck in the hopper from time to time, making it impossible to feed. Workers need to clear the blockage, which is troublesome and affects the processing efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a plastic pulverizer equipped with a quantitative feeding anti-clogging mechanism to solve the problem mentioned in the background art where plastic easily gets stuck inside the hopper.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a plastic pulverizer equipped with a quantitative feeding anti-clogging mechanism, comprising a grinding chamber, a drive motor fixedly mounted on the side surface of the grinding chamber, and the output end of the drive motor penetrating through the outer surface of the grinding chamber, a grinding roller rotatably mounted inside the grinding chamber, the grinding roller being inclined and connected to the drive motor, an opening on the outer surface of the grinding chamber, and a material box fixedly mounted on the outer surface of the grinding chamber, an eccentric block rotatably mounted on the outer surface of the material box, and a transmission rotation mechanism provided between the eccentric block and the grinding chamber, thereby preventing the plastic inside the material box from accumulating and clogging.

[0005] Preferably, the transmission rotation mechanism includes: a first pulley, which is fixedly mounted on the outer surface of the grinding roller shaft, and the grinding roller and the first pulley are concentrically designed; a second pulley is fixedly mounted on the outer surface of the eccentric block shaft, and a belt is provided between the second pulley and the first pulley; the diameter of the second pulley is smaller than the diameter of the first pulley.

[0006] Using the above technical solution, the rotation of the grinding roller drives the first pulley to rotate, which in turn drives the second pulley to rotate. The second pulley then drives the eccentric block to rotate synchronously. The rotation of the eccentric block generates vibration, which is transmitted to the material box. The difference in diameter between the first and second pulleys allows the eccentric block to rotate faster and generate greater vibration. This vibration in the material box allows the plastic inside to move slowly, preventing blockage and maintaining the efficiency of grinding the plastic.

[0007] Preferably, a shock-absorbing pad is fixedly installed between the grinding chamber and the material box, and the inside of the material box is designed to be inclined. The discharge port of the material box is connected to the grinding chamber, and a dust cover is fixedly installed between the grinding chamber and the material box.

[0008] By adopting the above technical solution, the design of the shock-absorbing pad can prevent the material box from transmitting vibration to the grinding chamber when it is vibrating. At the same time, the designed dust cover can also prevent vibration from being transmitted to the grinding chamber.

[0009] Preferably, a transmission gear is fixedly installed at the end of the grinding roller away from the drive motor, and the transmission gear and the grinding roller are concentrically designed and mesh with each other. Protective covers are fixedly installed on the outer surfaces of both ends of the grinding box.

[0010] By adopting the above technical solution, the design of separating the transmission gear from the drive motor makes it more convenient to replace and maintain the drive motor and transmission gear. At the same time, the protective cover can shield the transmission gear, the first pulley, the second pulley, the eccentric block, and the belt, reducing damage caused by foreign objects and injury to the user.

[0011] Preferably, a baffle is slidably installed on the outer surface of the material box, and the baffle is designed to be inclined. A fixing screw is threaded on the outer surface of the material box, and the outer surface of the fixing screw is in contact with the outer surface of the baffle.

[0012] By adopting the above technical solution, the amount of plastic released can be controlled and blocked by the baffle plate. The baffle plate can be fixed by the fixing screw, so that the amount of plastic discharged from the material box can be controlled and discharged quantitatively, without discharging too much and affecting the grinding of plastic.

[0013] Preferably, a discharge port is fixedly opened on the side surface of the grinding box, and the discharge port is designed to be inclined. A top cover is fastened to the outer surface of the material box, and a rotating mechanism is provided on the outer surface of the top cover to prevent dust.

[0014] By adopting the above technical solution, the inclined design of the discharge port can facilitate the discharge of the material after grinding, and the snap-fit ​​top cover and flap can block the dust generated during grinding and feeding.

[0015] Preferably, the rotating mechanism includes: a flap, which is rotatably installed inside the top cover, and the outer surface of the top cover is in contact with the outer surface of the flap. One end of the flap penetrates the side surface of the top cover. A counterweight handle is fixedly installed on the outer surface of the rotating shaft of the flap. The outer surface of the grinding box is in close contact with the outer surface of the dust cover, and the outer surface of the dust cover is in close contact with the outer surface of the material box.

[0016] Using the above technical solution, when the plastic is put into the material box, it will come into contact with the tilted flap. When the weight of the plastic exceeds the weight limit of the counterweight handle, the flap will automatically open due to the weight of the plastic and drive the counterweight handle to rotate. This allows the flap to open automatically after the plastic is put into the material box and close automatically after feeding is completed. This prevents the dust generated during the grinding of the plastic from drifting outward and reduces the chance of dust being inhaled by workers.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the plastic pulverizer equipped with a quantitative feeding anti-clogging mechanism:

[0018] 1. When the drive motor rotates, the grinding roller will drive the first pulley to rotate together, so that the belt can drive the second pulley to rotate, and the eccentric block can rotate together. Through the diameter difference between the first pulley and the second pulley, the eccentric block can rotate more rapidly, thereby generating a greater eccentric vibration force, which can cause the material box to vibrate and move the plastic in the material box. This prevents the plastic in the material box from being stuck due to accumulation and cannot be discharged, so that workers do not need to manually clear the blockage, and can improve the stability of the plastic grinding output.

[0019] 2. As the drive motor drives the grinding roller to rotate, the grinding roller will rotate simultaneously through the meshing of the transmission gears. The rotation of the grinding roller will cause the first pulley to drive the second pulley and the eccentric block to rotate, so that the grinding roller can rotate and grind the powder while driving the plastic to vibrate and discharge.

[0020] 3. When adding plastic into the material bin, the plastic will first fall between the top cover and the flap. When the plastic accumulates to a certain weight exceeding the weight limit of the counterweight handle, the flap will automatically flip and open, causing the counterweight handle to rotate and rise. After the plastic on the flap has completely fallen into the material bin, the counterweight handle will automatically fall due to its weight and cause the flap to reset. This allows the flap to open automatically when adding plastic and close automatically after adding the material. At the same time, the dust cover can prevent dust from escaping, reducing the dust dispersion caused by grinding after adding plastic. Attached Figure Description

[0028] 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.

[0029] Please see Figure 1-6This utility model provides a technical solution: a plastic pulverizer with a quantitative feeding anti-clogging mechanism, including a grinding box 1, a drive motor 5 fixedly installed on the side surface of the grinding box 1, and the output end of the drive motor 5 penetrating through the outer surface of the grinding box 1, a grinding roller 3 rotatably installed inside the grinding box 1, the grinding roller 3 being inclined, and the grinding roller 3 being connected to the drive motor 5, an opening being provided on the outer surface of the grinding box 1, and a material box 2 fixedly installed on the outer surface of the grinding box 1, an eccentric block 8 rotatably installed on the outer surface of the material box 2, and a transmission rotation mechanism being provided between the eccentric block 8 and the grinding box 1, so that the plastic inside the material box 2 will not accumulate and clog.

[0030] The rotation of the drive motor 5 drives the grinding roller 3 to rotate, so that the grinding roller 3 can rotate to grind the plastic that falls into the grinding box 1, and the plastic can be stored in the material box 2.

[0031] The transmission rotation mechanism includes: a first pulley 6, which is fixedly installed on the outer surface of the shaft of the grinding roller 3, and the grinding roller 3 and the first pulley 6 are concentrically designed; a second pulley 7 is fixedly installed on the outer surface of the shaft of the eccentric block 8, and a belt 9 is provided between the second pulley 7 and the first pulley 6; the diameter of the second pulley 7 is smaller than the diameter of the first pulley 6.

[0032] As the grinding roller 3 rotates, the first pulley 6 is also rotated. The rotation of the first pulley 6 causes the belt 9 to drive the second pulley 7 to rotate. Through the diameter difference between the second pulley 7 and the first pulley 6, the eccentric block 8 can rotate faster. The vibration generated by the eccentric rotation of the eccentric block 8 can be transmitted to the material box 2, allowing the plastic put into the material box 2 to move slowly with the vibration. This prevents the plastic from accumulating and getting stuck inside the material box 2 and being unable to be discharged. The plastic can be stably discharged from the material box 2, so that the worker does not need to manually clear or knock it. The plastic can be discharged stably and easily for grinding.

[0033] A shock-absorbing pad 10 is fixedly installed between the grinding chamber 1 and the material box 2. The inside of the material box 2 is designed to be inclined. The discharge port of the material box 2 is connected to the grinding chamber 1. A dust cover 13 is fixedly installed between the grinding chamber 1 and the material box 2.

[0034] By setting the shock-absorbing pad 10, the vibration force of the material box 2 will not be transmitted to the grinding box 1 when the material box 2 vibrates and discharges, thus reducing the noise generated when the grinding box 1 and the material box 2 come into contact. The inclined design of the material box 2 makes it easier for the plastic to be discharged outwards. Furthermore, the dust cover 13 allows the connection between the material box 2 and the grinding box 1 to be flexible, preventing dust from flying outwards when the plastic is discharged and ground, and ensuring that the material box 2 vibrates without generating noise.

[0035] A transmission gear 4 is fixedly installed at the end of the grinding roller 3 away from the drive motor 5. The transmission gear 4 and the grinding roller 3 are concentrically designed and mesh with each other. Protective covers are fixedly installed on the outer surfaces of both ends of the grinding box 1.

[0036] The meshing rotation of the transmission gear 4 enables the grinding roller 3 to rotate in opposite directions to grind the plastic. The transmission gear 4, the first pulley 6, the second pulley 7, the eccentric block 8, and the belt 9 are protected by a protective cover, which reduces damage caused by foreign objects and improves the safety of workers during operation.

[0037] A baffle plate 11 is slidably installed on the outer surface of the material box 2, and the baffle plate 11 is designed to be inclined. A fixing screw 12 is threaded on the outer surface of the material box 2, and the outer surface of the fixing screw 12 is in contact with the outer surface of the baffle plate 11.

[0038] The inclined baffle 11 allows the plastic to be discharged more easily. At the same time, by controlling the opening and closing distance of the baffle 11 and fixing the baffle 11 with the fixing screw 12, the discharge amount of plastic inside the material box 2 can be adjusted, so that the amount of plastic discharged into the grinding box 1 can be adjusted and discharged into the grinding box 1 in a metered manner.

[0039] The side surface of the grinding box 1 is fixedly provided with a discharge port 17, and the discharge port 17 is designed to be inclined. The outer surface of the material box 2 is fastened with a top cover 14, and the outer surface of the top cover 14 is provided with a rotating mechanism, which can prevent dust.

[0040] After grinding is completed, the plastic powder will fall into the bottom of the grinding chamber 1 and be discharged outward through the discharge port 17. The inclined design of the discharge port 17 makes it easier for the plastic to be discharged outward.

[0041] The rotating mechanism includes: a flap 15, which is rotatably installed inside the top cover 14, and the outer surface of the top cover 14 is in contact with the outer surface of the flap 15. One end of the flap 15 passes through the side surface of the top cover 14. A counterweight handle 16 is fixedly installed on the outer surface of the rotating shaft of the flap 15. The outer surface of the grinding box 1 is in close contact with the outer surface of the dust cover 13, and the outer surface of the dust cover 13 is in close contact with the outer surface of the material box 2.

[0042] When plastic is fed into the material bin 2, it will first fall between the top cover 14 and the flap 15. When the amount of plastic accumulating on the flap 15 exceeds the weight of the counterweight 16, the flap 15 will automatically rotate due to the weight of the plastic and drive the counterweight 16 to rotate, so that the plastic can be automatically discharged into the material bin 2 as the flap 15 rotates. After the plastic is discharged, the counterweight 16 will automatically rotate to drive the flap 15 to reset, so that the flap 15 will automatically close after feeding and automatically open during feeding, so that the dust will not be blown out when the plastic is ground, improving the cleanliness of the site and reducing the hazards caused by workers inhaling dust.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
