Description

Technical Field

[0001] This application relates to the field of equipment technology for plastic pellet production and processing, and in particular to a turnover box for plastic pellet production and processing. Background Technology

[0002] In the production and processing of plastic granules, turnover boxes are important tools for material storage, transportation, and transfer. Traditional plastic granule turnover boxes have relatively limited functions, mostly only having simple storage capabilities, and cannot meet the needs of screening and vibration treatment of plastic granules during the production process.

[0003] On the one hand, during the production of plastic granules, the granule size may be uneven. Traditional turnover boxes do not have screening functions, requiring additional screening equipment. This not only increases equipment costs and floor space but also makes the production process more cumbersome and reduces production efficiency. For example, in some small plastic processing plants, due to limited space, adding additional screening equipment will make the production space more crowded and inconvenient for workers. At the same time, manual screening is not only inefficient but also difficult to guarantee in terms of screening accuracy, affecting product quality.

[0004] On the other hand, plastic granules are prone to accumulating and clumping during handling, affecting subsequent processing. Traditional turnover boxes cannot vibrate the plastic granules, making it difficult to solve this problem. Manually stirring the accumulated and clumped plastic granules is not only labor-intensive but also ineffective and may introduce impurities, affecting the quality of the plastic granules.

[0005] Therefore, a turnover box for the production and processing of plastic granules is invented to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to provide a turnover box for the production and processing of plastic granules, which solves the problem that the existing turnover boxes have only one function and cannot achieve the screening, vibration treatment and inconvenience of moving and fixing plastic granules.

[0007] This application provides a turnover box for the production and processing of plastic granules, which adopts the following technical solution:

[0008] The device includes a fixed base shell, on which a housing assembly is mounted. The housing assembly includes hopper assemblies arranged sequentially from top to bottom. The hopper assemblies are used to receive and screen plastic granules. A vibrating assembly capable of vibrating the hopper assemblies is mounted inside the fixed base shell. The vibrating assembly includes a vibrating seat that can slide up and down. A lifting assembly is mounted on the vibrating seat. The lifting assembly is used to drive the hopper assemblies to move up and down. A feeding hopper is located at the top of the lifting assembly and is positioned directly above the hopper assemblies.

[0009] Optionally, the hopper assembly includes a collecting hopper, the bottom of which is provided with a sliding hopper, and the sliding hopper is provided with screening holes.

[0010] Optionally, the size of the screening holes on the hopper assembly decreases from top to bottom.

[0011] Optionally, the vibration assembly further includes multiple springs disposed at the bottom of the vibration seat, the bottom of the springs being fixed to the fixed base shell, the springs being used to support the housing assembly and provide vibration damping, and also includes a vibration motor disposed at the bottom of the vibration seat, the vibration motor being used to drive the housing assembly to generate vibration.

[0012] Optionally, the lifting assembly includes scissor-type lifting structures disposed on both sides of the housing assembly. The scissor-type lifting structure includes multiple cross-hinged connecting rods, with sliders hinged to the ends of the connecting rods. The sliders are slidably connected to their corresponding hopper assemblies. The lifting of the hopper assemblies can be achieved by driving the scissor-type lifting structure. A driving structure for driving the scissor-type lifting structure is disposed on the vibrating seat. One end of the bottom of the scissor-type lifting structure is hinged to the vibrating seat, and the other end can move horizontally along the vibrating seat. One end of the top of the scissor-type lifting structure is hinged to the feed hopper, and the other end can move horizontally along the feed hopper.

[0013] Optionally, the drive structure includes a rotatable rotating screw, which is rotatably connected to the vibration base. One end of the rotating screw is provided with a hand crank, and a sliding rod is threadedly connected to the rotating screw. The sliding rod drives the scissor lift structure to extend and retract by rotating the hand crank.

[0014] Optionally, the bottom of the fixed base is equipped with casters with brakes to facilitate the movement and fixation of the turnover box.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] 1. Screening function: The hopper assembly includes a collecting hopper and a sliding hopper with screening holes, and the size of the screening holes decreases from top to bottom. This allows for the grading and screening of plastic particles, ensuring that the plastic particles entering the subsequent processing stage are of uniform size and improving product quality.

[0017] 2. Vibration function: The spring and vibration motor in the vibration assembly work together. The spring supports the box assembly and provides vibration buffer, while the vibration motor drives the box assembly to vibrate. This can effectively prevent plastic granules from accumulating and clumping during turnover, which facilitates subsequent processing.

[0018] 3. Lifting function: The lifting component adopts a scissor-type lifting structure, which can realize the lifting of the hopper component through the drive structure, making it convenient to connect with equipment of different heights, meeting the needs of different production scenarios, and improving the applicability of the turnover box.

[0027] Reference Figure 1 , Figure 2One embodiment is shown as follows: A fixed base shell 1 serves as the basic support structure, providing stable support for the entire turnover box. Space is reserved inside for installing the vibration assembly 4. The hopper assembly 3 in the box assembly 2 is positioned above the fixed base shell 1. The hopper assembly 3 receives plastic granules falling from the feed hopper 7 and performs a screening function through its own structure. The vibration assembly 4 is located inside the fixed base shell 1. The vibration seat 5 and the fixed base shell 1 are connected vertically via a guide structure (such as a guide rail and slider 15). This connection method ensures that the vibration seat 5 maintains a stable trajectory during vibration, preventing deviation. A lifting assembly 6 is installed on the vibration seat 5. The lifting assembly 6 operates with the support of the vibration seat 5, driving the hopper assembly 3 to lift. The feed hopper 7 is positioned on top of the lifting assembly 6, ensuring that the feed hopper 7 can rise and fall synchronously with the movement of the lifting assembly 6 and is located directly above the hopper assembly 3, ensuring that the plastic granules can fall smoothly into the hopper assembly 3.

[0028] The implementation principle of the above embodiment is as follows: the fixed base shell 1 provides a stable mounting foundation for each component of the turnover box, and the hopper assembly 3 receives and screens plastic granules. When the vibration assembly 4 is working, the vibration seat 5 slides up and down inside the fixed base shell 1, driving the hopper assembly 3 to vibrate through vibration, preventing accumulation and clumping. When it is necessary to adjust the height of the hopper assembly 3, the lifting assembly 6 moves on the vibration seat 5, driving the hopper assembly 3 and the feed hopper 7 to rise and fall synchronously to adapt to different production needs.

[0029] Reference Figure 3 One embodiment shown is as follows: the hopper assembly 3 mainly consists of a collecting hopper 8 and a sliding hopper 9. In this embodiment, the collecting hopper 8 is used to collect plastic particles falling from the feeding hopper 7, and its bottom is slidably connected to the sliding hopper 9. The sliding hopper 9 can slide up and down on the collecting hopper 8. The screening holes 10 on the sliding hopper 9 are the key structure for realizing the screening of plastic particles. Screening holes 10 of different sizes can classify and screen plastic particles.

[0030] The implementation principle of the above embodiment is as follows: after the plastic particles fall from the feed hopper 7 into the collection hopper 8, under the action of gravity, the smaller plastic particles fall through the screening holes 10 on the sliding hopper 9 and fall to the bottom, while the larger plastic particles remain in the sliding hopper 9, thus achieving preliminary screening.

[0031] Reference Figure 1 , Figure 3One embodiment is shown where the screening holes 10 on the sliding hopper 9 in the hopper assembly 3 exhibit a specific size distribution. In this embodiment, the screening holes 10 on the upper layer of the sliding hopper 9 are larger, while the size of the screening holes 10 on the lower layer decreases sequentially. This size distribution ensures that during the descent of the plastic particles, larger particles are blocked by the upper screening holes 10, while smaller particles pass through the screening holes 10 of different sizes in sequence, achieving finer grading and screening. The size differences between the screening holes 10 are rationally designed to meet the particle size requirements of different production processes for plastic particles.

[0032] The implementation principle of the above embodiment is as follows: plastic particles enter the sliding hopper 9 from the collection hopper 8 under the action of gravity. Larger particles are first blocked by the larger screening holes 10 in the upper layer. As the particles continue to accumulate and vibrate, smaller particles pass through the screening holes 10 in the lower layer with gradually decreasing size in sequence, thereby realizing the grading and screening of plastic particles, ensuring that the screened plastic particles have uniform particle size and meet the requirements of subsequent processing.

[0033] Reference Figure 4 , Figure 5 One embodiment shown is as follows: the vibration assembly 4 consists of a vibration seat 5, a spring 11, and a vibration motor 12. In this embodiment, the top of the spring 11 is fixed to the bottom of the vibration seat 5 by welding, bolting, or other methods, and the bottom of the spring 11 is fixed to the fixed base shell 1 at a specific installation position on the fixed base shell 1 by welding or bolting. This connection method allows the spring 11 to stably support the vibration seat 5 and the box assembly 2, while also acting as a buffer during vibration, reducing the impact of vibration on the overall structure of the turnover box. The vibration motor 12 is also installed at the bottom of the vibration seat 5 and can be tightly connected to the vibration seat 5 by bolting or other methods, ensuring that the vibration generated by the vibration motor 12 can be efficiently transmitted to the vibration seat 5, thereby driving the entire box assembly 2 to vibrate.

[0034] The implementation principle of the above embodiment is as follows: After the vibration motor 12 is started, the generated vibration directly acts on the vibration seat 5, and the vibration seat 5 moves up and down under the drive of the vibration motor 12. At this time, the spring 11 set at the bottom of the vibration seat 5 plays a supporting and buffering role, stretching when the vibration seat 5 rises and compressing when it falls, absorbing vibration energy and avoiding damage to the turnover box due to excessive vibration amplitude. At the same time, the vibration of the vibration seat 5 drives the hopper assembly 3 in the box assembly 2 to vibrate, so that the plastic particles can pass through the screening holes 10 more smoothly during the screening process, preventing accumulation and clumping, and ensuring the stability and reliability of the turnover box during the vibration process.

[0035] Reference Figure 3 , Figure 5One embodiment shown is as follows: the lifting assembly 6 consists of a scissor lift structure 13 and a drive structure 16. In this embodiment, the scissor lift structure 13 is arranged on both sides of the housing assembly 2. Each scissor lift structure 13 is composed of multiple cross-hinged connecting rods 14, which are hinged together by hinge shafts. This hinged arrangement allows the connecting rods 14 to rotate relative to each other, thereby realizing the extension and retraction of the scissor lift structure 13. A slider 15 is hinged to the end of the connecting rod 14. A slide rail matching the slider 15 is provided on the side of the hopper assembly 3. The slider 15 is slidably connected to the slide rail, so that the scissor lift structure 13 can drive the hopper assembly 3 to move stably up and down during the extension and retraction process. One end of the bottom of the scissor lift structure 13 is hinged to the vibrating seat 5 by a hinge shaft, and the other end is set in the guide groove on the vibrating seat 5, allowing it to move horizontally along the guide groove. One end of the top of the scissor lift structure 13 is hinged to the feed hopper 7 by a hinge shaft, and the other end is set in the guide groove on the feed hopper 7, allowing it to move horizontally along the guide groove. The drive structure 16 is mounted on the vibration seat 5 and is used to drive the extension and retraction of the scissor lift structure 13.

[0036] The implementation principle of the above embodiment is as follows: When the drive structure 16 is working, it drives the scissor lift structure 13 to extend and retract. When the scissor lift structure 13 extends, its bottom moves horizontally along the vibrating seat 5, and its top moves horizontally along the feed hopper 7. Through the relative rotation of the connecting rod 14 and the sliding of the slider 15 on the slide rail of the hopper assembly 3, the hopper assembly 3 is driven to rise. When the scissor lift structure 13 retracts, the hopper assembly 3 descends. In this way, the hopper assembly 3 is raised and lowered to adapt to different production height requirements.

[0037] Reference Figure 1 , Figure 4 , Figure 6 One embodiment shown is as follows: the drive structure 16 mainly consists of a rotating screw 17, a hand crank 18, and a sliding rod 19. In this embodiment, the rotating screw 17 is mounted on the vibrating seat 5 via rotating connecting components such as bearings, enabling it to rotate stably on the vibrating seat 5. One end of the rotating screw 17 is fixedly connected to the hand crank 18, allowing the operator to rotate the rotating screw 17 by turning the hand crank 18. The sliding rod 19 is connected to the rotating screw 17 via a thread. When the rotating screw 17 rotates, due to the principle of threaded transmission, the sliding rod 19 moves along the axial direction of the rotating screw 17. The sliding rod 19 is hinged to the connecting rod 14 in the scissor lift structure 13, and its movement can drive the scissor lift structure 13 to extend and retract.

[0038] The implementation principle of the above embodiment is as follows: the operator turns the hand crank 18, which drives the rotating screw 17 to rotate. The rotating screw 17 causes the sliding rod 19 to move through the threaded transmission. The movement of the sliding rod 19 drives the connecting rod 14 of the scissor-type lifting structure 13 that is hinged to it to move, thereby realizing the extension and retraction of the scissor-type lifting structure 13, and thus driving the hopper assembly 3 to rise and fall. The operation is simple and convenient, and the height of the hopper assembly 3 can be flexibly adjusted according to actual production needs.

[0039] Reference Figure 1 , Figure 2 , Figure 5 One embodiment shown is as follows: A movable wheel 20 with brakes is installed at the bottom of the fixed base 1. In this embodiment, the movable wheel 20 is connected to the fixed base 1 via an axle and a mounting base. The mounting base and the fixed base 1 can be fixed by welding, bolting, or other methods to ensure the movable wheel 20 is securely installed. Each movable wheel 20 is equipped with a braking device, which is mechanically connected to the movable wheel 20. When the turnover box needs to be moved, the braking device is released, allowing the movable wheel 20 to rotate freely, facilitating the movement of the turnover box on the production site. When the turnover box needs to be fixed, the braking device is activated, mechanically securing the movable wheel 20 and ensuring the turnover box is placed stably.

[0040] The implementation principle of the above embodiment is as follows: During the production process, when it is necessary to move the turnover box to different positions, the operator releases the brake device of the moving wheel 20, pushes the turnover box, and the moving wheel 20 rolls on the ground to realize the movement of the turnover box; when it reaches the designated position and the turnover box needs to be fixed for operation, the operator activates the brake device, the brake device prevents the moving wheel 20 from rotating, and the turnover box is firmly fixed on the ground. The operation is simple and convenient, and the flexibility and stability of the turnover box are improved.

[0041] The working principle of this device is as follows: During use, the turnover box is first fixed in a designated position by the braked casters 20 at the bottom. Then, plastic granules are poured into the feed hopper 7, falling into the hopper assembly 3. The sliding hopper 9 of the hopper assembly 3 has screening holes 10, which are larger at the top and smaller at the bottom, achieving grading and screening of the plastic granules under gravity. During screening, the vibration motor 12 at the bottom of the vibrating seat 5 starts, driving the vibrating seat 5 up and down. The bottom spring 11 provides support and cushioning, reducing the impact of vibration on the box body and making the vibration more stable. This, in turn, drives the entire box assembly 2 to vibrate, preventing the plastic granules from accumulating and clumping, and helping them pass smoothly through the screening holes 10. To adjust the height of the hopper assembly 3, the hand crank 18 on the rotating screw 17 is turned. The screw rotation drives the threaded sliding rod 19 to move, which in turn pulls the scissor-type lifting structure 13 to extend and retract, achieving synchronous lifting and lowering of the hopper assembly 3 and the feed hopper 7 to adapt to different production needs. After production is completed, the brakes on the casters 20 are released, allowing the turnover box to be moved flexibly to the desired position.

[0042] The working principle of this device has been explained through the above embodiments. These embodiments only illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
