Description

Technical Field

[0001] This utility model relates to powder mixing technology for XPE board production, specifically to a technology that facilitates powder feeding, mixing, and automatic unloading. Background Technology

[0002] XPE board is a closed-cell foam material made primarily of low-density polyethylene (LDPE) through cross-linking and foaming processes. It possesses excellent flexibility, thermal insulation, cushioning, water resistance, and chemical stability, and is widely used in automotive interiors, building insulation, electronic cushioning, packaging, and sporting goods.

[0003] The production process of XPE sheets mainly includes raw material preparation, uniform mixing of raw materials, melt mixing, and extrusion to form sheets (plates). In the early stages of production, it is necessary to ensure uniform mixing of raw materials, such as LDPE (low-density polyethylene), and other added powders such as crosslinking agents, foaming agents, and other auxiliary materials.

[0004] The initial mixing of these raw materials is crucial; a uniform mixture is essential. Otherwise, uneven cross-linking reactions can easily occur during the later melt mixing process, leading to insufficient product performance. Furthermore, existing mixing equipment is difficult to use during the mixing and outflow process, prone to clogging, and the bottom-opening pipe outlet method requires a significant amount of space, resulting in a complex equipment layout.

[0005] Therefore, it is necessary to improve the existing equipment for mixing and feeding powder used in XPE board production, so that the feeding of the mixed material is easier and the problems of easy blockage and difficulty in cleaning when feeding from a single pipe can be avoided. Utility Model Content

[0006] Therefore, the technical problem to be solved by this utility model is to overcome the shortcomings of the prior art, thereby providing a technology that facilitates the rotation and tilting of the mixing equipment so that the material can flow out quickly, thus achieving rapid feeding and convenient cleaning.

[0007] To achieve the above objectives, this utility model provides a powder mixing and feeding device for XPE board production, including a feeding component, a mixing component, and a flipping component; The feeding assembly is located upstream of the mixing assembly;

[0008] The mixing assembly includes a mixing container, a stirring rod, a first support body, and a second support body. The stirring rod is disposed below the mixing container, and its two ends are rotatably connected to the first support body and the second support body. A drive motor is disposed inside the first support body and is connected to the stirring rod. The flipping assembly is disposed at the position of the second support body. The flipping assembly is driven to connect to the outer shell, which is fixedly connected to the mixing container and is fitted over the outside of the stirring rod.

[0009] In a preferred embodiment, the feeding assembly includes a concave cabinet with an opening and closing door on the upper side of the middle portion of the concave cabinet. The upper side of the opening and closing door is connected to an opening cylinder, and the mixing container is disposed on the other side of the concave cabinet at the height of the opening and closing door.

[0010] A preferred embodiment further includes a pressing assembly having a mounting frame, a pressing cylinder, and a pressing plate. The mounting frame is located on the downstream side of the concave cabinet and on the upper part of the mixing container. The pressing cylinder is mounted on the mounting frame, and the telescopic rod of the pressing cylinder is connected to the pressing plate. The pressing plate is vertically and flexibly located at the upper opening of the mixing container.

[0011] A preferred embodiment is that the upper opening edge of the mixing container has an arc-shaped extension structure, which cooperates with the mounting frame.

[0012] In a preferred embodiment, the flipping assembly is a worm gear structure, wherein the worm is connected to the flipping motor and the worm wheel is connected to the outer casing.

[0013] In a preferred embodiment, the flipping assembly is a gear and rack structure, wherein the gear is connected to one end of the housing, the rack is connected to the flipping cylinder, and the rack engages with the gear.

[0014] The beneficial effects of this invention are as follows: Material is fed into the mixing assembly via a feeding component, and after mixing, it is tilted and discharged via a tilting component. Specifically, the mixing process is achieved by rotating a stirring rod between the first and second supports. Furthermore, when tilting is required for discharge, the tilting component drives the outer shell to tilt, which in turn tilts the mixing container to discharge the material. This allows the material in the mixing container 21 to be easily poured out through a wide opening, avoiding blockages caused by a single narrow outlet. Moreover, the tilting and tilting exposes the entire interior of the mixing container, facilitating cleaning. Attached Figure Description

Detailed Implementation

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] First embodiment: like Figure 1 , Figure 2 As shown, the present invention provides a powder mixing and feeding device for XPE board production, including a feeding component 10, a mixing component 20 and a flipping component 30; The feeding assembly 10 is located on the upstream side of the mixing assembly 20; The mixing assembly 20 includes a mixing container 21, a stirring rod 22, a first support 23, and a second support 24. The stirring rod 22 is disposed below the mixing container 21, and both ends of the stirring rod 22 are rotatably connected to the first support 23 and the second support 24. A drive motor 25 is disposed on the outside of the first support 23, and the drive motor 25 is connected to the stirring rod 22 (the drive motor 25 is connected to the stirring rod 22 using an existing reduction gear to achieve drive). The tilting assembly 30 is disposed at the position of the second support 24. The flipping assembly 30 is driven to connect to the outer shell 26, which is fixedly connected to the mixing container 21. The outer shell 26 is sleeved on the outside of the stirring rod 22. The stirring rod 22 can rotate relative to the outer shell 26.

[0021] In practical applications, the material is fed into the mixing component 20 via the feeding component 10 and mixed. After mixing, the material is then discharged via the tilting component 30. Specifically, the mixing process is achieved by rotating the stirring rod 22, which rotates between the first and second supports. Furthermore, when discharge is required, the tilting component drives the outer shell 26 to tilt, which in turn tilts the mixing container 21 to discharge the material. This allows the material inside the mixing container 21 to be easily poured out through a wide opening, avoiding blockages caused by a single narrow outlet. Moreover, the tilting mechanism exposes the entire interior of the mixing container 21, facilitating cleaning.

[0022] A preferred solution is, as Figure 3 As shown, the feeding assembly 10 includes a concave cabinet 11, with an opening and closing door 12 on the upper side of the middle part of the concave cabinet 11. The upper side of the opening and closing door 12 is connected to the opening cylinder 13, and the mixing container 21 is arranged on the other side of the height of the opening and closing door 12 in the concave cabinet 11.

[0023] The feeding assembly 10 controls the opening and closing door 12 to rise or fall, thereby opening the inlet of the opening and closing door 12 for feeding the material to be mixed; that is, after the material is fed in through the opening and closing door 12, it enters the mixing container 21 on the other side for mixing and stirring.

[0024] Second embodiment: A preferred solution is, as Figure 2 , Figure 4 As shown, the system also includes a pressing assembly 40, which has a mounting frame 41, a pressing cylinder 42, and a pressing plate 43. The mounting frame 41 is located on the downstream side of the concave cabinet 11 and is situated above the mixing container 21. The pressing cylinder 42 is mounted on the mounting frame 41, and its telescopic rod 421 is connected to the pressing plate 43. The pressing plate 43 is vertically and flexibly positioned at the upper opening of the mixing container 21. The mounting frame 41 has a hollow structure for the lifting and lowering of the pressing plate 43.

[0025] When mixing is carried out in the mixing container 21, in order to prevent the material from overflowing, the upper part of the mixing container 21 is pressed down by the pressing plate 43, so that the material is pressed down and kept at the lower position of the mixing container 21 during the mixing.

[0026] A preferred embodiment is that the upper opening edge of the mixing container 21 is an arc-shaped extension structure 211, which cooperates with the mounting frame 41. This ensures that when the mixing container 21 tilts or flips, it will not touch the lower edge of the mounting frame 41.

[0027] Third embodiment: A preferred solution is, as Figure 4 As shown, the flipping assembly 30 is a worm gear structure 31, the worm 311 is connected to the flipping motor 313, and the worm wheel 312 is connected to the outer shell 26.

[0028] Power is provided by the flip motor 313, which causes the worm gear 311 to rotate, thereby driving the worm wheel 312 to rotate, which in turn causes the outer casing 26 to rotate. When the outer casing 26 rotates, it simultaneously drives the mixing container 21 to rotate, thereby causing the mixing container 21 to flip and discharge the material.

[0029] When the mixing container 21 is tilted, it rotates around the axis of the stirring rod 22. One end of the stirring rod 22 is connected to the drive end of the first support 23, and the other end 221 of the stirring rod 22 is rotatably connected to the outer end of the second support 24. The stirring rod 22 is disposed inside the outer shell 26, and the two are independently disposed, that is, the rotation of the stirring rod 22 will not interfere with the outer shell 26, and the rotation of the outer shell 26 will not affect the stirring rod 22.

[0030] A preferred solution is, as Figure 5As shown, the flipping assembly 30 is a gear and rack structure 32. The gear 321 is connected to one end of the outer casing 26, and the rack 322 is connected to the flipping cylinder 323. The rack 322 and the gear 321 cooperate with each other. Another driving method is also provided: the rack 322 is driven to move by the extension rod of the flipping cylinder 323, which in turn drives the gear 321 to rotate. The gear 321 then causes the outer casing 26 to rotate, thereby achieving the flipping of the mixing container 21.

[0031] The powder mixing in this invention is, for example, the processing and preparation of various raw material powders for XPE (chemically cross-linked polyethylene foam). The added materials include, for example, polyethylene (PE) resin, foaming agent, cross-linking agent, lubricant, and other powders. These various powders are existing technologies and will not be described in detail here.

[0032] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
