Description

Technical Field

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

[0002] Plastic raw material processing equipment is the core equipment for plastic pretreatment. It can accurately mix the base resin of plastic with plasticizers, stabilizers and other additives according to the formula to produce uniform premix / compound.

[0003] Some small production plants often use manual weighing of additives and then add them directly to the mixing equipment. When adding directly by opening the lid, not only is it easy for raw materials to scatter and cause waste, but large-area opening of the lid can also cause the raw materials to become damp and cause dust to fly, thus affecting the uneven performance of the mixture. In addition, when adding by opening the lid, personnel are likely to accidentally touch the high-speed stirring blades inside the mixing cylinder, which cannot ensure operational safety. Therefore, this utility model provides a mixing equipment for plastic raw material processing to meet the needs. Utility Model Content

[0004] The technical problem this utility model aims to solve is to provide a formulation device for processing plastic raw materials. By setting up formulation components, it is possible to quickly add additives without opening the container lid or accidentally touching the stirring blades. This not only reduces material waste and dust, but also provides safety for operators. The formulation components are interconnected in structure and function, complementing each other. This design can solve the problem that some small production plants easily waste raw materials and affect the safety of operators when adding additives by directly opening the lid.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A formulation device for processing plastic raw materials includes a formulation cylinder, a cylinder cover rotatably connected to one side near the top of the formulation cylinder, mounting grooves symmetrically opened on both sides of the formulation cylinder, and a feeding chamber fixedly connected to the inner wall of the mounting groove; and a formulation component for facilitating the addition of additives, the formulation component being connected to the formulation cylinder.

[0008] Optionally, an avoidance groove is provided on the inner wall of the mounting groove corresponding to the position of the limiting rod. The inner wall dimension of the avoidance groove is larger than the outer wall dimension of the limiting rod, and the sliding groove communicates with the avoidance groove.

[0009] Optionally, a groove is provided at the bottom of the feeding chamber, and a uniformly distributed weakening groove is provided on one side of the inner wall of the groove.

[0010] Optionally, the inner wall of the feeding chamber is an arc-shaped curved surface structure, and the circular structure formed by the rotation of the scraper is adapted to the arc-shaped structure of the inner wall of the feeding chamber.

[0011] Optionally, the scraper has inclined portions at both ends, the inclined portions having an outward tilting angle, and the inclined portions being centrally symmetrically distributed.

[0012] Optionally, the distance between the two ends of the scraper and the free end of the cover plate and the center of the scraper is the same.

[0013] Optionally, the two ends of the connecting rod are fixedly connected to the scraper and the cover plate, respectively, and the connecting rod has evenly distributed protrusions fixedly connected to it.

[0014] Optionally, the free end of the lever has an L-shaped structure, and the outer contour dimension of the lever is smaller than the inner wall dimension of the groove.

[0015] Optionally, a stirring blade is rotatably connected to the bottom of the inner wall of the preparation cylinder, and the inner diameter of the cylinder cover is adapted to the outer diameter of the preparation cylinder.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above scheme, the addition of additives can be achieved quickly by setting up the preparation components. Moreover, during the addition process, there is no need to open the cylinder cover or accidentally touch the stirring blades. This not only reduces raw material waste and dust, but also provides safety for operators. The preparation components are interlocked in structure and function, complementing each other.

[0018] By setting up a scraper and a cover plate, the opening of the installation groove can be switched between open and closed states by using the different positions of the scraper and the cover plate. The connecting rod makes it easy to adjust the position of the scraper and the cover plate, which is convenient for the user to pull by hand. The free end of the scraper is provided with an inclined part, which makes it easy to scrape off the additives remaining on the inner wall of the feeding chamber.

[0019] By setting up a lever and a limit lever, the limit lever can be used to limit the two sides of the scraper and the connecting rod in both states, restricting the continued rotation of the scraper and the cover plate, thereby ensuring the structural stability in a certain state.

[0020] By setting grooves and weakening grooves, the feeding chamber protrudes from the outer contour surface of the preparation cylinder. The grooves are set at the bottom of the feeding chamber. When it is necessary to move or transport the preparation cylinder, you can put your hand inside the groove. The weakening grooves increase the friction between your hand and the groove, making it easier to grip the cylinder and preventing your hand from slipping. This ensures the safety of moving or transporting the entire equipment. Attached Figure Description

[0039] like Figures 1 to 9 As shown, this embodiment of the present invention provides a preparation device for processing plastic raw materials, including a preparation cylinder 1. A cylinder cover 2 is rotatably connected to one side of the preparation cylinder 1 near the top. A stirring blade 14 is rotatably connected to the bottom of the inner wall of the preparation cylinder 1. The inner diameter of the cylinder cover 2 is adapted to the outer diameter of the preparation cylinder 1. Installation grooves 3 are symmetrically opened on both sides of the preparation cylinder 1, and a feeding chamber 4 is fixedly connected to the inner wall of the installation groove 3. A preparation component is also provided, which is used to facilitate the addition of additives. The preparation component is connected to the preparation cylinder 1. The preparation device provided in this application is mainly suitable for some small production plants, where additives are often weighed manually. The mixing equipment is directly added to the mixing chamber. The mixing chamber 1 is mainly responsible for providing a mixing space for plastic raw materials and additives. The cover 2 is used to seal the mixing chamber 1 to prevent dust from escaping and external moisture and impurities from entering during mixing. The stirring blade 14 is used to stir the raw materials and additives at high speed. The feeding chamber 4 is used to facilitate the addition of additives. By setting up the mixing components, not only can the addition of additives be realized quickly, but also during the addition process, there is no need to open the cover 2 or accidentally touch the stirring blade 14. This not only reduces raw material waste and dust, but also provides safety for operators. The mixing components are interlocked in structure and function, complementing each other.

[0040] As one implementation method in this embodiment, such as Figures 1 to 9As shown, the preparation assembly includes a feeding chamber 4 fixedly connected to the inner wall of the mounting groove 3. A groove 12 is formed at the bottom of the feeding chamber 4, and uniformly distributed weakening grooves 13 are formed on one side of the inner wall of the groove 12. A scraper 5 is rotatably connected to the inner wall of the mounting groove 3. The inner wall of the feeding chamber 4 has an arc-shaped curved surface structure. The circular structure formed by the rotation of the scraper 5 matches the arc-shaped structure of the inner wall of the feeding chamber 4. A cover plate 6 is fixedly connected to the center of one side of the scraper 5. Inclined portions 15 are provided at both ends of the scraper 5, each with an outward tilting angle. The inclined portions 15 are centrally symmetrically distributed. The distance between the two ends of the scraper 5 and the free end of the cover plate 6 and the center of the scraper 5 is... The cover plate 6 is fixedly connected to two sides with symmetrically distributed connecting rods 7. The two ends of the connecting rods 7 are fixedly connected to the scraper 5 and the cover plate 6 respectively. The connecting rods 7 are fixedly connected with evenly distributed protrusions. The outer wall of the preparation cylinder 1 is provided with a sliding groove 8. The sliding groove 8 is slidably connected with a lever 9. The free end of the lever 9 has an L-shaped structure. The outer contour structure dimension of the lever 9 is smaller than the inner wall dimension of the sliding groove 8. The side of the lever 9 is fixedly connected with symmetrically distributed limiting rods 10. The inner wall of the mounting groove 3 is provided with a clearance groove 11 corresponding to the position of the limiting rod 10. The inner wall dimension of the clearance groove 11 is larger than the outer wall dimension of the limiting rod 10. The sliding groove 8 and the clearance groove 11 are interconnected.

[0041] Specifically, mounting grooves 3 are symmetrically provided on both sides of the dispensing cylinder 1, and the mounting grooves 3 are in communication with the internal space of the dispensing cylinder 1 (e.g., Figures 4 to 5As shown), a feeding chamber 4 is fixedly connected to the inner wall of the mounting groove 3. The height of the feeding chamber 4 is smaller than the height of the inner wall of the mounting groove 3. The inner wall of the feeding chamber 4 is a quarter-circle arc structure. The center of the arc of the inner wall of the feeding chamber 4 is on the same axis as the center of the scraper 5. The circle formed by the rotation of the scraper 5 and the cover plate 6 matches the arc of the inner wall of the feeding chamber 4. The cover plate 6 is located at the center of the scraper 5. Both sides of the cover plate 6 are fixedly connected to the scraper 5 by connecting rods 7. The scraper 5, the cover plate 6 and the connecting rods 7 are manufactured as a single piece. The connecting rod 7 is located at the end near the limit rod 10. The connecting rod 7 has a wave-shaped protrusion to facilitate gripping and increase friction. By gripping the connecting rod 7 and pulling, the scraper 5 and the cover plate 6 can rotate clockwise or counterclockwise synchronously. When in use, first pour the plastic raw material into the preparation cylinder 1, then tighten the cylinder cover 2. A drive motor is connected to the bottom of the stirring blade 14, driving the stirring blade 14 to rotate at high speed. The specific structure and working principle of the drive motor and stirring blade 14 are disclosed as existing technology and will not be elaborated further. Start the drive motor to rotate the stirring blade 14, thereby stirring the raw material. When additives need to be added, first adjust the closed state of the scraper 5 and the cover plate 6 to the open state. When the cover plate 6 is horizontal, the scraper 5 is vertical, and the cover plate 6 is located on the scraper 5 near the feeding chamber 4, the lever 9 slides to the side near the scraper 5 and locks. At this time, the limiting rod 10 protrudes from the clearance groove 11, and the two limiting rods 10 are located on both sides of the scraper 5. This state is the closed state of the scraper 5 and the cover plate 6 (e.g., Figures 7 to 8 As shown), the opening of the mounting groove 3 is blocked by the scraper 5 and the cover plate 6. The limiting rod 10 limits the two sides of the scraper 5 to ensure that the scraper 5 and the cover plate 6 are stable and will not rotate. When the cover plate 6 rotates into the interior of the dispensing cylinder 1, the scraper 5 is in an inclined state. The lever 9 slides to the side close to the scraper 5 and locks. At this time, the limiting rod 10 protrudes from the clearance groove 11, and the two limiting rods 10 are located on both sides of the connecting rod 7. This state is the open state of the scraper 5 and the cover plate 6 (as shown). Figure 9As shown, the opening of the mounting groove 3 is kept open by tilting the scraper 5 to facilitate the addition of additives. The limiting rod 10 limits the two sides of the connecting rod 7 to ensure that the scraper 5 and the cover plate 6 are stable and will not rotate. When it is necessary to rotate the scraper 5 and the cover plate 6 to switch between the two states, first slide the lever 9 to the side away from the scraper 5 and lock it. The limiting rod 10 is stored inside the clearance groove 11, so as not to affect the free rotation of the scraper 5 and the cover plate 6. Then, pull the connecting rod 7 to drive the scraper 5 to rotate. After rotating to the correct position, slide the lever 9 to the side close to the scraper 5 and lock it to switch between the two states. Here, the locking of the lever 9 is achieved by changing the inner wall size of the slide groove 8. The width of the inner wall of the slide groove 8 gradually decreases at both ends, so that the inner wall size of the two ends of the slide groove 8 matches the outer contour size of the lever 9, increasing the friction and facilitating the limiting of the lever 9. The inner size of the middle of the slide groove 8 is larger than the outer contour size of the lever 9, which facilitates sliding.

[0042] By setting scraper 5 and cover plate 6 in cooperation, the opening of the mounting groove 3 can be switched between open and closed states by using different positions of scraper 5 and cover plate 6. The connecting rod 7 makes it easy to adjust the position of scraper 5 and cover plate 6, which is convenient for users to pull by hand. The free end of scraper 5 is provided with an inclined part 15, which makes it easy to scrape off the additives remaining on the inner wall of feeding chamber 4.

[0043] By setting up the lever 9 and the limiting rod 10 in cooperation, the limiting rod 10 can be used to limit the two sides of the scraper 5 and the connecting rod 7 in both states, restricting the continued rotation of the scraper 5 and the cover plate 6, thereby ensuring the structural stability in a certain state.

[0044] Furthermore, the scraper 5 has inclined portions 15 at both ends. When the additive is added in the open state, since the additive may be liquid or solid, the inclined portions 15 facilitate the scraping of any residual additive on the inner wall of the feeding chamber 4. When the scraper 5 is switched from the open state to the closed state, the free end of the top scraper 5, i.e., the inclined portion 15 (as shown in the image), is used to scrape away any remaining additive. Figure 6 As shown), the scraper 5 rotates downwards along the arc-shaped inner wall of the feeding chamber 4, thereby scraping off the residual additives on the inner wall of the feeding chamber 4 and concentrating them inside the mixing cylinder 1, facilitating complete mixing of the additives and ensuring uniform performance of the mixture. The scraper 5 and cover plate 6 do not contact the stirring blade 14 during rotation to ensure they do not interfere with each other. Furthermore, the bottom of the feeding chamber 4 is provided with a groove 12 and a weakening groove 13 that work together (as shown). Figures 7 to 8As shown), the feeding chamber 4 is symmetrically distributed on both sides of the preparation cylinder 1 and protrudes from the outer contour of the preparation cylinder 1. The feeding chamber 4 facilitates the overall movement of the preparation cylinder 1. Hands can be placed inside the groove 12. The weakening groove 13 increases the friction between the hand and the groove 12, making it easy to grip the force point during handling, preventing slippage, and ensuring the safety of handling or moving the entire configuration equipment.

[0045] By setting the groove 12 and the weakening groove 13, the feeding chamber 4 protrudes from the outer contour surface of the preparation cylinder 1. The groove 12 is set at the bottom of the feeding chamber 4. When it is necessary to move or transport the preparation cylinder 1, the hand can be placed inside the groove 12. The weakening groove 13 increases the friction between the hand and the groove 12, making it easier to grip the cylinder during transport. This prevents the hand from slipping and ensures the safety of transporting or moving the entire equipment.

[0046] The working principle of the technical solution provided by this utility model is as follows:

[0047] In use, first pour the plastic raw material into the preparation cylinder 1, then tighten the cylinder cover 2. A drive motor is connected to the bottom of the stirring blade 14. Starting the drive motor rotates the stirring blade 14, thus stirring the raw material. When adding additives, first adjust the scraper 5 and cover plate 6 from closed to open. Grasp the top connecting rod 7 and the bottom connecting rod 7 in sequence to push the cover plate 6 into the preparation cylinder 1. When the cover plate 6 rotates into the preparation cylinder 1, the scraper 5 is tilted, and the lever 9 slides to the side closest to the scraper 5 and locks. At this time, the limiting rod 10 protrudes from the clearance groove 11, and the two limiting rods 10 are respectively located on the connecting rod 7. On both sides, the scraper 5 is tilted to keep the opening of the mounting groove 3 open, facilitating the addition of additives. The limiting rod 10 is used to limit the two sides of the connecting rod 7, ensuring that the scraper 5 and the cover plate 6 are stable and will not rotate. After adding the additives, the lever 9 is slid to the side away from the scraper 5 and locked. The limiting rod 10 is stored inside the clearance groove 11, so as not to affect the free rotation of the scraper 5 and the cover plate 6. Then, the connecting rod 7 is grasped by hand to pull the cover plate 6 from the inside of the mixing cylinder 1 to the side closer to the feeding chamber 4 until the cover plate 6 is horizontal and the scraper 5 is vertical. The lever 9 is slid close to the scraper 5. The limit rod 10 protrudes from the clearance groove 11 and is locked on one side. At this time, the two limit rods 10 are located on both sides of the scraper 5. The scraper 5 and the cover plate 6 are adjusted to the closed state. During the process of adjusting from the open state to the closed state, the free end of the top scraper 5, i.e. the inclined part 15, moves downward along the arc-shaped inner wall of the feeding chamber 4, thereby scraping off the residual additives on the inner wall of the feeding chamber 4 and concentrating them inside the mixing cylinder 1, so as to facilitate the complete mixing of the additives and ensure the uniform performance of the mixture. In addition, the bottom of the feeding chamber 4 is provided with a groove 12 and a weakening groove 13 to cooperate. The feeding chambers 4 are symmetrically distributed on both sides of the mixing cylinder 1. The side protrudes from the outer contour of the preparation cylinder 1. The feeding chamber 4 facilitates the overall movement of the preparation cylinder 1. Hands can be placed inside the groove 12. The weakening groove 13 increases the friction between the hand and the groove 12, making it easy to grip during handling and preventing slippage. This ensures the safety of handling or moving the entire equipment. This device not only allows for the rapid addition of additives, but also eliminates the need to open the cylinder cover 2 or accidentally touch the stirring blade 14 during the addition process. This reduces raw material waste and dust, and provides safety for operators. The overall structure and function are interconnected and complementary.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
