Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, and more specifically, to a screening device for plastic processing. Background Art

[0002] Plastic processing is a general term for various processes that convert synthetic resins or plastics into plastic products. It has developed with the development of synthetic resins. It promotes the development of plastic machinery. In order to process plastics into the required accessories or products, compression molding, extrusion molding, injection molding or blow molding are usually used.

[0003] In order to facilitate better processing performance during subsequent mixing and molding, it is usually necessary to screen the plastic raw materials to make them uniform in particle size. Therefore, a screening device is required. The current screening device separates materials of different particle sizes through the vibration of the sieve plate to achieve screening operations. However, during screening, in order to ensure that the material does not splash out from the feed port, a lid is usually used to seal it during operation. This will result in the lid needing to be opened for adding raw materials when it is necessary. At this time, the newly added material splashes out of the device due to the vibration of the sieve plate, resulting in material waste. The plastic raw materials are usually fine particles. At this time, if the scattered particles are collected, the workload will increase and work efficiency will be reduced. In addition, the vibration efficiency of the existing vibration device is not high, resulting in low screening efficiency. Therefore, it is necessary to improve and optimize it.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figures 1 to 7 As shown, the utility model provides a screening device for plastic processing, comprising a working box 1, with material distribution ports 2 fixedly installed on both sides of the working box 1, and a housing 3 fixedly installed on the top of the working box 1;

[0031] A material discharge mechanism, fixedly mounted inside the housing 3;

[0032] The screening mechanism is fixedly installed inside the working box 1;

[0033] The vibration mechanism is fixedly installed inside the working box 1 and is located below the screening mechanism;

[0034] Among them, the unloading mechanism includes an inlet 4 fixedly installed on the top of the outer shell 3, and a conveying shaft 6 is rotatably installed inside the outer shell 3. The conveying shaft 6 is located below the inlet 4. The conveying shaft 6 is fixedly connected to a motor 5, and the motor 5 is fixedly installed on the outer wall of the outer shell 3. A motor 2 7 is also fixedly installed on the outer wall of the outer shell 3. The output shaft of the motor 2 7 passes through the interior of the outer shell 3 and is fixedly connected to the unloading shaft 8.

[0035] When the plastic material needs to be screened, the staff starts the motor 1 5 and the motor 2 7, and then pours the material into the housing 3 through the feed port 4. At this time, the operation of the motor 1 5 drives the conveying shaft 6 to rotate and pushes the material, and the operation of the motor 2 7 drives the unloading shaft 8 to rotate. The rotation of the unloading shaft 8 causes the material to fall into the working box 1 in batches. At this time, the material falls on the top of the screen plate 10 and the screening operation begins. At this time, the staff starts the drive motor 15. The operation of the drive motor 15 provides power for the transmission rod 16. At this time, the transmission block 17 rotates, and the rotation of the transmission block 17 drives the piston rod 18 to rotate. At this time, the piston rod 18 and the vibrating head 19 are active. The vibration head 19 is movably installed in the limiting groove 14, so that the piston rod 18 continuously drives the vibration head 19 to hit the screen plate 10 upward. At this time, the impact frequencies of the two groups of vibration heads 19 are different, which makes the vibration of the screen plate 10 more frequent. When the screen plate 10 is hit and moves upward, the pressure plate 11 also moves upward. At this time, the spring 13 is compressed, so that the pressure plate 11 clamps the screen plate 10 to prevent the screen plate 10 from detaching. At this time, materials of the same particle size can be collected through the distribution port 2 and the collecting tank 21, and the staff can lift the pull rod 12 to stop the pressure plate 11 from fixing the screen plate 10. At this time, the staff can replace or clean the screen plate 10.

[0036] Through the operation of motor 1 5 and motor 2 7, the plastic materials continuously and in batches fall onto the top of the screen plate 10, and then driven by the driving motor 15, the vibration head 19 continuously vibrates the screen plate 10, so that the screen plate 10 starts to screen, and the screen plate 10 is fixed by the cooperation of the pressure plate 11 and the spring 1 13. Compared with the traditional device, the device can transport materials while performing screening operations through the operation of the unloading mechanism, and the materials will not be vibrated and scattered, and the vibration mechanism is operated to make the vibration head 19 continuously knock on the screen plate 10, thereby improving the screening efficiency.

[0037] Among them, it also includes a collecting mechanism movably installed inside the working box 1;

[0038] A fixing mechanism, movably mounted on the outer wall of the collecting mechanism;

[0039] Among them, the collecting mechanism includes a collecting trough 21 movably installed inside the working box 1, the collecting trough 21 is located at the bottom of the screen mechanism, the collecting trough 21 is fixedly connected to a fixed plate 22, the fixed plate 22 is located outside the working box 1, and the fixed plate 22 is movably connected to one end of the fixing mechanism.

[0040] During the screening operation, plastic particles of different sizes can be collected from the distribution port 2, and the material with the smallest size will eventually fall into the collecting tank 21. At this time, the staff can push the pull rod three 25 outward after the screening operation is completed. At this time, the pull rod three 25 moves outward, so that the latch 24 is disengaged from the inside of the working box 1. At this time, the staff can pull out the pull rod two 23 to complete the collection of the materials. After the collection is completed, the staff puts it back into the collecting tank 21 and releases the pull rod three 25. At this time, due to the elasticity of the spring two 26, the latch 24 enters the inside of the working box 1 to complete the fixation, thereby preventing the collection tank 21 from falling off due to the vibration of the working box 1.

[0041] By pulling the rod three 25 and the spring two 26, the staff can fix the collecting trough 21 to prevent it from detaching, and can easily disassemble it. Compared with the traditional device, the device collects materials through the cooperation of the collecting mechanism and the fixing mechanism, and has quick disassembly and stable installation, thereby improving the collection efficiency of the staff.

[0042] Among them, the screening mechanism includes a limit groove 9 fixedly installed inside the working box 1, and there are two groups of limit grooves 9, each of which has a sieve plate 10 movably installed inside. A pressure plate 11 is also movably installed inside the limit groove 9, and the pressure plate 11 is located on the top of the sieve plate 10. The pressure plate 11 is fixedly connected to a pull rod 12, and one end of the pull rod 12 passes through the top of the limit groove 9. The pressure plate 11 and the limit groove 9 are elastically connected by a spring 13, and a limit groove 2 14 is fixedly installed at the bottom of the limit groove 9.

[0043] When the sieve plate 10 is hit and moves upward, the pressure plate 11 also moves upward. At this time, the spring 13 is compressed, so that the pressure plate 11 clamps the sieve plate 10 to prevent the sieve plate 10 from detaching. At this time, materials of the same particle size can be collected through the feed port 2 and the collecting trough 21. The staff can lift the pull rod 12 to stop the pressure plate 11 from fixing the sieve plate 10. At this time, the staff can replace or clean the sieve plate 10.

[0044] Among them, the vibration mechanism includes a driving motor 15 fixedly installed on the outer wall of the working box 1, the driving motor 15 and the transmission rod 16 are fixedly connected to provide power for the transmission rod 16, the transmission rod 16 is rotatably installed inside the fixed block 20, and the fixed block 20 is fixedly installed inside the working box 1, the transmission rod 16 and the transmission block 17 are fixedly connected, the transmission block 17 and the piston rod 18 are rotatably connected, the piston rod 18 and the vibration head 19 are movably connected, and the vibration head 19 is movably installed inside the limiting groove 14.

[0045] The staff starts the drive motor 15, and the operation of the drive motor 15 provides power for the transmission rod 16. At this time, the transmission block 17 rotates, and the rotation of the transmission block 17 drives the piston rod 18 to rotate. At this time, the piston rod 18 and the vibration head 19 are movably connected, and the vibration head 19 is movably installed inside the limit groove 14, so that the piston rod 18 continuously drives the vibration head 19 to impact the screen plate 10 upward. At this time, the impact frequencies of the two groups of vibration heads 19 are different, which makes the vibration of the screen plate 10 more frequent.

[0046] Among them, the fixing mechanism includes a pin 24 movably installed inside the fixing plate 22, one end of the pin 24 passes through the fixing plate 22 and is located inside the working box 1, the pin 24 and the pull rod three 25 are fixedly connected, and the pull rod three 25 and the outer wall of the fixing plate 22 are elastically connected by a spring two 26.

[0047] After the screening operation is completed, the staff can push the pull rod 3 25 outward, and the pull rod 3 25 moves outward, so that the latch 24 is separated from the interior of the working box 1. At this time, the staff can pull out the pull rod 23 outward to complete the collection of the materials.

[0048] There are two groups of vibration mechanisms, both of which are arranged below the sieve plate 10, and the vibration head 19 is movably installed inside the limiting groove 14, and the vibration head 19 passes through the bottom of the limiting groove 19 and contacts the sieve plate 10.

[0049] There are two groups of screening mechanisms, both of which are fixedly installed inside the working box 1 and slightly inclined, and the two groups of screen plates 10 are movably installed on one side of the material distribution port 2.

[0050] The working principle and use process of this utility model:

[0051] When the plastic material needs to be screened, the staff starts the motor 1 5 and the motor 2 7, and then pours the material into the housing 3 through the feed port 4. At this time, the operation of the motor 1 5 drives the conveying shaft 6 to rotate and pushes the material, and the operation of the motor 2 7 drives the unloading shaft 8 to rotate. The rotation of the unloading shaft 8 causes the material to fall into the working box 1 in batches. At this time, the material falls on the top of the screen plate 10 and the screening operation begins. At this time, the staff starts the drive motor 15. The operation of the drive motor 15 provides power for the transmission rod 16. At this time, the transmission block 17 rotates, and the rotation of the transmission block 17 drives the piston rod 18 to rotate. At this time, the piston rod 18 and the vibrating head 19 are active. The vibration head 19 is movably installed in the limiting groove 14, so that the piston rod 18 continuously drives the vibration head 19 to hit the screen plate 10 upward. At this time, the impact frequencies of the two groups of vibration heads 19 are different, which makes the vibration of the screen plate 10 more frequent. When the screen plate 10 is hit and moves upward, the pressure plate 11 also moves upward. At this time, the spring 13 is compressed, so that the pressure plate 11 clamps the screen plate 10 to prevent the screen plate 10 from detaching. At this time, materials of the same particle size can be collected through the distribution port 2 and the collecting tank 21, and the staff can lift the pull rod 12 to stop the pressure plate 11 from fixing the screen plate 10. At this time, the staff can replace or clean the screen plate 10.

[0052] During the screening operation, plastic particles of different sizes can be collected from the distribution port 2, and the material with the smallest size will eventually fall into the collecting tank 21. At this time, the staff can push the pull rod three 25 outward after the screening operation is completed. At this time, the pull rod three 25 moves outward, so that the latch 24 is disengaged from the inside of the working box 1. At this time, the staff can pull out the pull rod two 23 to complete the collection of the materials. After the collection is completed, the staff puts it back into the collecting tank 21 and releases the pull rod three 25. At this time, due to the elasticity of the spring two 26, the latch 24 enters the inside of the working box 1 to complete the fixation, thereby preventing the collection tank 21 from falling off due to the vibration of the working box 1.
