Description

Technical Field

[0001] This utility model relates to the technical field of hollow board production equipment, and in particular to a high-efficiency and uniform feeding device for a hollow board production line. Background Technology

[0002] Hollow core sheet (commonly known as hollow core sheet) is a type of plastic sheet with excellent properties such as light weight, high strength, corrosion resistance, and antistatic properties. It is widely used in packaging, construction, advertising, and other industries. The main workflow of a hollow core sheet production line is to uniformly mix various types of raw materials according to different formula ratios and then feed them into the inlet. The raw materials are heated and plasticized by a high-temperature extruder, then extruded through a mold, and finally processed into finished products through traction, shearing, and other processes.

[0003] In existing technologies, traditional feeding devices often lack sufficient uniform control mechanisms. This deficiency makes it easy for materials to accumulate or clog during the feeding process, which not only affects the flowability of the materials but also directly affects the quality and efficiency of subsequent extrusion molding. When the materials are not evenly distributed during the feeding stage, it may lead to uneven density and unstable physical properties of the molded products, which in turn has an adverse impact on the reliability and market competitiveness of the products.

[0004] Therefore, it is necessary to provide a new high-efficiency and uniform feeding device for hollow board production lines to solve the above-mentioned technical problems. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0030] Please see Figures 1 to 5 This utility model provides a high-efficiency and uniform feeding device for a hollow board production line, which includes:

[0031] Mixing box 1, with a protective box 6 fixed at the top center of the mixing box 1, and a uniform mixing component 5 inside the mixing box 1;

[0032] The uniform mixing component 5 includes a drive motor 501, which is fixedly connected inside the protective box 6. The output end of the drive motor 501 extends into the mixing box 1 through a coupling and is fixed with a fixing rod 502. A connecting block 503 is symmetrically fixed on the surface of the fixing rod 502 near the drive motor 501. A first stirring rod 504 is fixed on the outer side of the connecting block 503 through a rotating shaft. A spiral blade 507 is fixed on the surface of the fixing rod 502 away from the drive motor 501.

[0033] By placing the drive motor 501 inside the protective box 6, it provides dust and interference protection, improving the motor's service life and operational reliability. The drive motor simultaneously drives the first stirring rod 504 and the spiral vane 507 to rotate via the fixed rod 502, enabling multiple mixing and lifting actions to be completed with a single power source. This results in a compact structure, lower energy consumption, and higher efficiency. The symmetrically arranged connecting blocks 503 and the first stirring rod 504 form the basic mixing frame, ensuring the balance and stability of the mixing force.

[0034] The top two sides of the mixing box 1 are symmetrically fixed with feed pipes 7, the bottom wall of the mixing box 1 is slidably connected with baffle plate 2, the baffle plate 2 is controlled to slide by electric pulley 4, and the bottom of the mixing box 1 is fixed with support frame 3.

[0035] A quantitative feeding component is installed above the feed pipe.

[0036] In the embodiments of this utility model, please refer to Figure 2 The surface of the first stirring rod 504 is symmetrically and staggered at equal distances with a material-turning plate 505. The two sets of material-turning plates 505 are vertically distributed, and an arc groove 506 is provided on one side of the material-turning plate 505.

[0037] The symmetrical fixed layout with equidistant staggered arrangement makes the mixing force more evenly distributed in the axial and radial directions, eliminating mixing dead zones and avoiding the problem of over-mixing in one area and under-mixing in another. The two sets of tilting plates 505 are vertically distributed, forming diverse material movement paths, so that the material is subjected to strong shearing and convection in both the horizontal and vertical directions, resulting in better mixing. The design of the arc-shaped groove 506 on one side of the tilting plate 505 reduces mixing resistance and energy consumption. It can pick up a small amount of material and scatter it during rotation, simulating the "lifting" action, promoting the diffusion and mixing of materials, which is particularly beneficial for the uniform dispersion of powder materials and preventing agglomeration.

[0038] In the embodiments of this utility model, please refer to Figure 2 An auxiliary stirring rod 508 is fixed at a corresponding position on the surface of the fixed rod 502 that is perpendicular to the connecting block 503. A scraper 509 is fixed at the end of the auxiliary stirring rod 508 that is away from the fixed rod 502.

[0039] During the mixing process, materials adhering to the tank wall are continuously scraped off and re-mixed, ensuring that all materials are effectively utilized. This avoids product quality defects caused by deterioration of materials adhering to the wall or distortion of the formula ratio, while keeping the heat exchange wall surface clean and ensuring stable heat exchange efficiency.

[0040] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 The bottom wall of the mixing box 1 is provided with a groove 101 for the baffle plate 2 to slide. The sides of the groove 101 are provided with slide rails 102 at the corresponding positions of the electric pulley 4. The electric pulley 4 forms a limiting structure for the baffle plate 2 through the slide rails 102.

[0041] The sliding of the baffle plate 2 is precisely controlled by the electric pulley 4 within the slide rail 102, thereby realizing the automatic and smooth opening and closing of the discharge port.

[0042] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The inner wall of the mixing box 1 is provided with a reaction chamber 103. The inner side wall of the reaction chamber 103 is in contact with the outer side wall of the scraper 509. The outer side wall of the scraper 509 is arc-shaped, and the cross-sectional shape of the scraper 509 is a right triangle. The inclined surface of the scraper 509 is opposite to the spiral blade 507.

[0043] The scraped material is guided downwards along the slope of the scraper and falls directly into the working range of the rotating spiral blade 507 below. It is then quickly lifted by the spiral blade and thrown back into the mixing flow, forming an efficient internal cycle of "scraping-lifting-remixing", which greatly enhances the mixing effect and efficiency.

[0044] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 The height of the spiral blade 507 is half the height of the inner side of the reaction chamber 103, and the maximum diameter of the spiral blade 507 is the same as the inner diameter of the reaction chamber 103.

[0045] This ensures that the spiral blades have sufficient height to effectively lift the material at the bottom, while not excessively interfering with the main mixing area dominated by the first stirring rod 504 above. This allows the lifting and mixing to coexist harmoniously with the main mixing without interfering with each other. At the same time, the gap between the spiral blades and the cavity wall is extremely small, which can maximize the lifting of the material and prevent the material from short-circuiting between the spiral blades and the cavity wall without being lifted, while also avoiding interference with the scraper 509.

[0046] In the embodiments of this utility model, please refer to Figure 3 A guide groove 104 is provided above the reaction chamber 103, and the inclined angle of the guide groove 104 is 45° to 60°.

[0047] It ensures that the material slides smoothly into the mixing chamber by gravity without accumulating at the inlet; it also avoids the situation where the material falls too fast due to an angle that is too small, causing dust to fly or impacting the bottom mixing components, while an angle that is too large may cause the material to stick to the inclined surface.

[0048] In the embodiments of this utility model, please refer to Figure 4 The quantitative feeding component 8 includes a housing 801, which is fixedly connected to the top of the feed pipe 7. The inner wall of the housing 801 is provided with a conveying groove 806 communicating with the feed pipe 7. A ball 802 is provided at the center of the inner wall of the housing 801. A connecting rod 803 is fixed to the bottom end of the ball 802. One end of the connecting rod 803 extends to the bottom wall of the housing 801 and a knob 804 is fixed thereon. A scale groove 805 is provided on the side wall of the knob 804. A first circular hole 807 is provided on both sides of the ball 802. A second circular hole 808 is provided on both sides of the ball 802 that are perpendicular to the first circular hole 807. A feed pipe 809 is installed at the top of the housing 801.

[0049] By rotating the sphere 802, the alignment of the first circular hole 807 or the second circular hole 808 on it with the conveying groove 806 can be changed to switch different flow orifice diameters, thereby realizing two quantitative modes: coarse or fine.

[0050] The knob 804 and scale groove 805 provide a clear operating interface and quantitative reference, enabling operators to accurately control and repeat the same amount of material.

[0051] In the embodiments of this utility model, please refer to Figure 4 The sphere 802 is tightly fitted to the inner wall of the shell 801, and the sphere 802 rotates around the rotation axis of the connecting rod 803;

[0052] The tight fit ensures the ball valve's sealing performance, effectively preventing material leakage during non-feeding positions or switching processes, avoiding waste and contamination. The rotation around the axis of the connecting rod 803 defines its motion mode, ensuring the stability and reliability of rotational switching.

[0053] In the embodiments of this utility model, please refer to Figure 4 The diameter of the first circular hole 807 is twice the diameter of the second circular hole 808, and materials can pass through the inner sides of both the first circular hole 807 and the second circular hole 808.

[0054] The difference in diameter directly determines the flow capacity. The larger diameter first hole is used for rapid feeding of large flow rates, while the smaller diameter second hole is used for precise feeding of small flow rates.

[0055] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0056] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
