Abstract
Description
Technical Field
[0001] This utility model relates to the field of foam technology, and in particular to a lifting-type stirring device for foaming. Background Technology
[0002] The foaming process of foam requires the thorough mixing of main and auxiliary materials such as plastic particle raw materials, foaming agents, crosslinking agents, and accelerators to ensure the consistency of foaming effect. The equipment used is a mixing device. After the various materials are thoroughly mixed, the mixture is transferred to a foaming molding device with a molding cavity for foaming and molding to obtain the desired shape of foam with good foaming effect.
[0003] In traditional foam mixing devices, mechanically driven agitators are often used inside containers such as barrels that hold the main and auxiliary materials of foam. The agitator can only stir the mixture along its rotation path. Whether the materials can be thoroughly mixed is an important factor affecting the quality of the finished foam product. The blade design of conventional agitators results in a small coverage area, which leads to poor mixing effect for foam materials with high viscosity, resulting in unstable product quality. Therefore, it is necessary to improve the structure of the agitator to achieve better mixing effect of foaming materials. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide a lifting-type foam stirring device to solve the above problems.
[0005] The present invention adopts the following technical solution:
[0006] This utility model first provides a lifting foam stirring device, which includes a mounting platform, a stirring tank and a lifting stirring mechanism.
[0007] The mounting platform includes a platform and supporting legs connected below the platform; the mixing tank is placed upright on the platform for holding the foaming mixture; the lifting mixing mechanism includes a guide rail screw, a load-bearing platform, a mixing drive motor, and a mixing paddle. The guide rail screw is vertically fixed on the platform, and the mixing paddle is connected to the output shaft of the mixing drive motor and driven to rotate by the mixing drive motor. The mixing drive motor is locked to the load-bearing platform, and the load-bearing platform is slidably connected to the guide rail screw for driving the mixing drive motor and the mixing paddle to move up and down above the mixing tank. The mixing tank has multiple cutting blades arranged on its inner wall. The projections of these blades onto the bottom of the mixing tank are on the same circumference. The mixing paddle includes a central disk and blades connected to the central disk. A set of blades extending outwards along the outer circumference of the central disk gradually increases the distance between the far end of each blade and the central disk. Adjacent blades are not on the same horizontal plane. The orthographic projections of each blade onto the bottom of the mixing tank are all within the circumferential trajectory formed by the arrangement of the multiple cutting blades.
[0008] Preferably, two sets of blades are connected to the central disk, and the two sets of blades are symmetrical about the central disk.
[0009] Preferably, the spacing between any two adjacent blades in the two sets of blades is equal.
[0010] Preferably, the blade includes parallel blades parallel to the plane of the central disk and inclined blades extending from the parallel blades, the parallel blades and the inclined blades being connected end to end.
[0011] Preferably, multiple cutting blades extend from the bottom of the mixing tank to the top of the tank in a spiral path around the central axis of the mixing tank.
[0012] Preferably, a positioning groove is provided in the center of the mounting platform, and the bottom of the mixing tank is embedded in the positioning groove.
[0013] Preferably, the lifting foam stirring device further includes a lifting drive motor for driving the load-bearing platform to lift, and a timer is connected to the lifting drive motor.
[0014] The technical effects achieved by this utility model include:
[0015] In the aforementioned lifting-type foam mixing device, the blades of the mixing paddle extend outwards gradually, and adjacent blades are not on the same horizontal plane. The blades can form different mixing paths on multiple horizontal planes. Furthermore, the load-bearing platform drives the mixing drive motor and the mixing paddle to move up and down above the mixing tank. The mixing paddle can move blades corresponding to different outward extension distances to different heights. Compared with conventional mixing paddles, it can cover more horizontal planes inside the tank, thereby expanding the mixing range and effectively improving the mixing effect. Even for foam main materials and auxiliary materials with high viscosity, it can be fully mixed, thereby obtaining finished foam with stable quality and high yield, avoiding rework mixing, and effectively improving the mixing efficiency. Through the arrangement of multiple cutting blades on the inner wall of the mixing tank, when the mixing paddle rotates under the drive of the mixing drive motor, the fixed cutting blades and the material mixture driven by the mixing paddle interact with each other. The cutting blades can fill the gaps of the mixing paddle that cannot get too close to the inner wall of the mixing tank. The two work together to further fully mix the mixture located next to the inner wall of the mixing tank, improving the mixing effect. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Examples of these preferred embodiments are illustrated in the drawings. The embodiments of this utility model shown in and described with reference to the drawings are merely exemplary, and this utility model is not limited to these embodiments.
[0024] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related are omitted.
[0025] like Figure 1 As shown in the figure, this utility model embodiment provides a lifting foam stirring device, which includes a mounting platform 1, a stirring tank 2, and a lifting stirring mechanism 3.
[0026] The mounting platform 1 includes a platform 11 and support legs 12 connected below the platform 11; the mixing tank 2 is placed upright on the platform 11 and is used to hold the foaming mixture; the lifting mixing mechanism 3 includes a guide rail screw 31, a load-bearing platform 32, a mixing drive motor 33, and a mixing paddle 34. The guide rail screw 31 is vertically fixed on the platform 11. The mixing paddle 34 is connected to the output shaft of the mixing drive motor 33 and is driven to rotate by the mixing drive motor 33. The mixing drive motor 33 is locked to the load-bearing platform 32. The load-bearing platform 32 is slidably connected to the guide rail screw 31 and is used to drive the mixing drive motor 33 and the mixing paddle 34 to move up and down above the mixing tank 2.
[0027] Combination Figure 2 and Figure 3 As shown, the inner wall of the mixing tank 2 is provided with a plurality of cutting blades 21. The projections of the plurality of cutting blades 21 on the bottom of the mixing tank 2 are located on the same circumference. The stirring paddle 34 includes a central disk 341 and blades 342 connected to the central disk 341. A set of blades 342 that gradually extend outward are arranged along the outer circumference of the central disk 341, so that the distance between the far end of each blade 342 and the central disk 341 gradually increases, and adjacent blades 342 are not on the same horizontal plane. The orthographic projection of each blade 342 on the bottom of the mixing tank 2 is inside the circumferential trajectory formed by the plurality of cutting blades 21.
[0028] Based on the above-mentioned lifting foam mixing device, the blades 342 of the mixing paddle 34 gradually extend outward, and adjacent blades 342 are not on the same horizontal plane. The blades 342 can form different mixing paths on multiple horizontal planes. Furthermore, by utilizing the characteristics of the lifting mechanism, as the load-bearing platform 32 drives the mixing drive motor 33 and the mixing paddle 34 to move up and down above the mixing tank 2, the mixing paddle 34 can move the blades 342 corresponding to different outward extension distances to different heights. Compared with conventional mixing paddles, it can cover more horizontal planes in the tank, thereby expanding the mixing range and effectively improving the mixing effect. Even for foam main materials and auxiliary materials with high viscosity, they can be fully mixed, thereby obtaining finished foam with stable quality and high yield, avoiding rework mixing, and effectively improving the mixing operation efficiency.
[0029] In addition, the multiple cutting blades 21 arranged on the inner wall of the mixing tank 2, when the stirring paddle 34 is driven by the stirring drive motor 33 to rotate, the fixed cutting blades 21 interact with the material mixture driven by the stirring paddle 34. The cutting blades 21 can thus make up for the gap of the stirring paddle 34 which cannot get too close to the inner wall of the mixing tank 2. The two work together to further and fully stir the mixture located next to the inner wall of the mixing tank 2.
[0030] In this embodiment, two sets of blades 342 are connected to the central disk 341, and the two sets of blades 342 are symmetrical about the central disk 341. In practical applications of the above-mentioned stirring paddle 34, the density of the blades 342 can be selected according to the requirements, so as to achieve sufficient stirring effect while realizing the required structural simplicity.
[0031] To maintain the structural balance of the agitator 34 after installation, the spacing between any two adjacent blades 342 in the two sets of blades 342 is equal, that is, the two sets of blades 342 are arranged in a centrally symmetrical manner.
[0032] To improve the stirring effect by varying the arrangement of the blades 342, the blades 342 include parallel blades 342a parallel to the plane of the central disk 341 and inclined blades 342b extending from the parallel blades 342a, with the parallel blades 342a and the inclined blades 342b connected end to end.
[0033] Furthermore, multiple cutting blades 21 extend from the bottom of the mixing tank 2 in a spiral path around the central axis of the mixing tank 2 to the top of the mixing tank 2, making the distribution of the cutting blades 21 more uniform and reasonable.
[0034] To prevent the mixing tank 2 from shaking during mixing operations and causing damage to the blades 342, a positioning groove is provided in the center of the platform 11 of the mounting platform 1, and the bottom of the mixing tank 2 is embedded in the positioning groove.
[0035] In this embodiment, the lifting foam stirring device further includes a lifting drive motor for driving the load-bearing platform 32 to lift. The lifting drive motor is connected to a timer, which controls the forward and reverse rotation of the lifting drive motor to start and stop at regular intervals, thereby realizing automated stirring with timed lifting.

[0037] The above description is only a specific embodiment of this application.
