Description

A raw material mixing device for processing plastic parts Technical Field

[0001] This utility model relates to the field of plastic processing equipment technology, and in particular to a raw material mixing device for processing plastic parts. Background Technology

[0002] Currently, raw material mixing is a crucial step in the processing of plastic parts. Plastic raw materials are prone to sticking to the mixing tank walls during mixing because they are mostly polymers with a certain degree of viscosity. Common thermoplastics such as polyethylene and polypropylene become even more viscous when heated and molten, making them even easier to adhere to the tank walls.

[0003] After the raw materials are mixed and adhere to the walls, they often need to be collected manually by the staff, which takes a long time. This is mainly because the staff will first collect the raw materials inside the mixing tank. After a certain amount of time has been spent collecting the raw materials, the materials adhering to the walls will become relatively dry. As a result, the materials adhering to the walls will be firmly attached and difficult to clean quickly using conventional methods. The staff can usually only collect the materials adhering to the walls of the mixing equipment little by little, and the limited operating space leads to low efficiency. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a raw material mixing device for processing plastic parts.

[0005] This utility model is achieved using the following technical solution: a raw material mixing device for plastic parts processing, comprising a mixing tank, a closed cover on the top of the mixing tank, a stepper motor on the top of the mixing tank, a mixing rod fixedly mounted on the output end of the stepper motor, the bottom end of the mixing rod penetrating the closed cover and extending into the interior of the mixing tank, a mixing component for mixing mounted on the mixing rod, a scraping component for collecting raw materials adhering to the walls of the mixing tank inside the mixing tank, a drive component for controlling the start and stop of the scraping component at the top of the mixing rod, the scraping component comprising a first semi-circular scraper disposed inside the mixing tank, a second semi-circular scraper disposed on one side of the first semi-circular scraper, the outer circumferential surfaces of the first and second semi-circular scrapers being in contact with the inner wall of the mixing tank.

[0006] Through the above technical solution, when it is necessary to clean the material adhering to the wall during the mixing process, the drive component can be activated to control the scraping component to scrape the inner wall of the mixing tank, effectively collecting the material adhering to the wall, reducing material waste, and improving the mixing effect and product quality.

[0007] As a further improvement to the above scheme, the bottom sides of both the first semi-circular scraper and the second semi-circular scraper are inclined.

[0008] The above technical solution allows the inclined bottom design to facilitate the scraping of raw materials by guiding them to the bottom of the mixing tank, making it easier for them to slide down to the bottom of the mixing tank. This makes it easier to collect and re-mix the raw materials and prevents them from re-adhering to the tank wall or accumulating on the scraper.

[0009] As a further improvement to the above solution, the top of the stirring rod is provided with a sliding port, and the driving assembly includes a first driving plate slidably disposed inside the sliding port. A second driving plate is fixedly installed on the bottom side of the first driving plate. The bottom end of the second driving plate extends downward through the closed cover into the interior of the stirring tank. Lifting blocks are rotatably installed on both sides of the bottom end of the second driving plate.

[0010] With the above technical solution, when the first drive plate and the second drive plate move, they can drive the lifting block to move, thereby realizing the control of the scraping component. The structure is simple and the operation is convenient.

[0011] As a further improvement to the above solution, lifting strips are fixedly installed on one side of both the first semi-circular scraper and the second semi-circular scraper, and one end of each of the two lifting blocks extends to the bottom of the adjacent lifting strip.

[0012] Through the above technical solution, the lifting block and the lifting strip cooperate. When the lifting block rises, the lifting strip can move a short distance. Then, the two lifting blocks will have space to rotate because they lose the contact with the inner wall of the sliding port. After the two lifting blocks rotate, they will lose the support force on the lifting strip, thereby allowing the first half-ring scraper and the second half-ring scraper to descend and collect the material hanging on the wall.

[0013] As a further improvement to the above solution, a movable ring is slidably sleeved at the top of the stirring rod. Both ends of the first drive plate extend out sliding openings and are fixedly installed with the inner ring surface of the movable ring. A threaded post is provided on one side of the movable ring. One end of the threaded post is threaded through the movable ring and abuts against the stirring rod. A rotating block is fixedly installed at the other end of the threaded post.

[0014] By rotating the threaded column, the moving ring can slide along the stirring rod, thereby driving the first drive plate, the second drive plate, and the lifting block to move, thus controlling the scraping component; the threaded column abuts against the stirring rod, which can fix the position of the moving ring and ensure the stability of the scraping component during operation.

[0015] As a further improvement to the above solution, sealing plates are fixedly installed on both sides of the second drive plate. Both sealing plates are located inside the sliding port, and one side of each sealing plate is fixedly connected to the sealing cover.

[0016] Through the above technical solution, the sealing plate can effectively prevent raw materials from entering the sliding port through the gap between the mixing rod and the sealing cover during the mixing process, avoid the accumulation of raw materials affecting the normal operation of the drive components, extend the service life of the equipment, and ensure the normal operation of the equipment.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention, by incorporating a scraping component and a drive component, can clean the raw materials adhering to the inner wall of the mixing tank during stirring and collection, reducing material waste and improving product quality. Simultaneously, the automated scraping control structure is easy to operate, and the sealed design effectively protects the drive component, extending equipment lifespan and improving production efficiency.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Referring to Figures 1-7, this embodiment of a raw material mixing device for plastic parts processing includes a mixing tank 1. The top of the mixing tank 1 is provided with a closed cover. A stepper motor 2 is provided on the top of the mixing tank 1. A mixing rod 3 is fixedly installed at the output end of the stepper motor 2. The bottom end of the mixing rod 3 passes through the closed cover and extends into the interior of the mixing tank 1. A mixing component 4 for mixing is installed on the mixing rod 3. A scraping component for collecting the raw material adhering to the wall inside the mixing tank 1 is provided inside the mixing tank 1. A drive component for controlling the start and stop of the scraping component is provided at the top of the mixing rod 3.

[0030] The scraping assembly includes a first semi-circular scraper 501 disposed inside the mixing tank 1, and a second semi-circular scraper 502 disposed on one side of the first semi-circular scraper 501. The outer ring surfaces of both the first semi-circular scraper 501 and the second semi-circular scraper 502 are in contact with the inner wall of the mixing tank 1. The bottom sides of both the first semi-circular scraper 501 and the second semi-circular scraper 502 are inclined. The inclined bottom design facilitates the scraping of raw materials by concentrating and guiding them, making them easier to slide to the bottom of the mixing tank 1, which is convenient for subsequent collection and re-mixing, and prevents the scraped raw materials from re-adhering to the tank wall or accumulating on the scraper.

[0031] The top of the stirring rod 3 has a sliding opening. The driving assembly includes a first driving plate 601 slidably disposed inside the sliding opening. A second driving plate 602 is fixedly installed on the bottom side of the first driving plate 601. The bottom end of the second driving plate 602 extends downward through the closed cover into the interior of the stirring tank 1. Lifting blocks 603 are rotatably installed on both sides of the bottom end of the second driving plate 602. When the first driving plate 601 and the second driving plate 602 move, they can drive the lifting blocks 603 to move, thereby realizing the control of the scraping assembly. The structure is simple and easy to operate. Lifting bars 7 are fixedly installed on one side of both the semi-ring scraper 501 and the second semi-ring scraper 502. One end of each of the two lifting blocks 603 extends to the bottom of the adjacent lifting bar 7. The lifting blocks 603 cooperate with the lifting bars 7. When the lifting blocks 603 rise, the lifting bars 7 can move a short distance. Then, the two lifting blocks 603 will have space to rotate because they lose the contact with the inner wall of the sliding opening. After the two lifting blocks 603 rotate, they will lose the support force on the lifting bars 7, thereby allowing the first semi-ring scraper 501 and the second semi-ring scraper 502 to descend and collect the material hanging on the wall.

[0032] A movable ring 8 is slidably fitted at the top of the stirring rod 3. Both ends of the first drive plate 601 extend into sliding openings and are fixedly installed on the inner ring surface of the movable ring 8. A threaded post 9 is provided on one side of the movable ring 8. One end of the threaded post 9 is threaded through the movable ring 8 and abuts against the stirring rod 3. A rotating block is fixedly installed at the other end of the threaded post 9. Rotating the threaded post 9 allows the movable ring 8 to slide along the stirring rod 3, thereby driving the first drive plate 601, the second drive plate 602, and the lifting block 603 to move, thus realizing the control of the scraping component. The threaded post 9 abuts against the stirring rod 3, which can fix the position of the movable ring 8 and ensure the stability of the scraping component during operation.

[0033] Sealing plates 10 are fixedly installed on both sides of the second drive plate 602. Both sealing plates 10 are located inside the sliding port. One side of each sealing plate 10 is fixedly connected to the sealing cover. The sealing plates 10 can effectively prevent raw materials from entering the sliding port from the gap between the stirring rod 3 and the sealing cover during the stirring process, avoid the accumulation of raw materials affecting the normal operation of the drive components, extend the service life of the equipment, and ensure the normal operation of the equipment.

[0034] The implementation principle of a raw material stirring device for plastic parts processing in this application embodiment is as follows: First, the plastic raw material is placed into the stirring tank 1, the sealing cover is closed, the stepper motor 2 is started, the stepper motor 2 drives the stirring main rod 3 to rotate, and the stirring component 4 on the stirring main rod 3 stirs the raw material.

[0035] When it is necessary to collect the raw materials inside the mixing tank 1 and the raw materials hanging on the inner wall, rotate the rotating block on the threaded column 9 to make the threaded column 9 rotate and loosen the fixation on the moving ring 8, and slide the moving ring 8 upward. The moving ring 8 drives the first drive plate 601 and the second drive plate 602 to move upward, and the lifting blocks 603 on both sides of the bottom end of the second drive plate 602 move upward accordingly.

[0036] The lifting block 603 works in conjunction with the lifting bar 7. When the lifting block 603 rises, the lifting bar 7 can move a short distance. Then, the two lifting blocks 603 will have room to rotate because they lose the contact with the inner wall of the sliding port. Since the moving ring 8 moves up a limited distance, the two lifting blocks 603 will not rotate into the inside of the sliding port, but will tilt and rest on both sides of the sliding port. After the two lifting blocks 603 rotate, they will lose the support force on the lifting bar 7. The lifting bar 7 will fall due to the loss of support, causing the first half-ring scraper 501 and the second half-ring scraper 502 to descend. During the descent, the first half-ring scraper 501 and the second half-ring scraper 502 will scrape off the inner wall of the mixing tank 1, thereby collecting the material stuck to the wall.

[0037] After collection, the staff only needs to clean and collect the bottom of the inner cavity of the mixing tank 1, and then open the closed cover to remove the first half-ring scraper 501 and the second half-ring scraper 502. This saves the staff time of collecting the entire inner wall of the mixing tank 1 and improves work efficiency.

[0038] When a new round of stirring is needed, simply slide the moving ring 8 down so that the two lifting blocks 603 can press against the bottom of the inner cavity of the sliding port again and become horizontal. Then, rotate the threaded column 9 to fix the moving ring 8. In this way, the position of the two lifting blocks 603 will be fixed, which can support the lifting bar 7, thereby supporting the first half-ring scraper 501 and the second half-ring scraper 502.

[0039] Throughout the mixing and scraping process, the sealing plates 10 on both sides of the second drive plate 602 always seal the gap between the mixing rod 3 and the closed cover, preventing raw materials from entering the sliding port and affecting the operation of the drive assembly.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
