Description

Technical Field

[0001] This utility model relates to the technical field of mixing devices, specifically a mixing device for slow rebound foaming raw material premix. Background Technology

[0002] Slow rebound foam is a type of polyurethane foam material with slow rebound properties, which is widely used in household products, industrial and medical fields, and some emerging fields.

[0003] Slow rebound foam raw materials need to be mixed and foamed before processing. Before mixing and foaming, a certain amount of various raw materials need to be premixed to facilitate subsequent quantitative foaming and improve production efficiency. However, due to the diversity of foam material specifications, conventional axial mixing and stirring devices require a longer time to ensure the uniformity of mixing, which affects production efficiency. Therefore, we propose a slow rebound foam raw material premixing and stirring device. Utility Model Content

[0012] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0013] 1. This utility model, through its ingredient-dispensing assembly, allows for the mixing of raw materials into a mixing tank. A motor drives the stirring shaft to rotate, and a mixing screen sweeps and mixes the various raw materials. The materials then fall through the screen and onto the screen plate. Once the materials have completely settled, a lifting device extends upwards, allowing the screen plate to pass over the diameter-changing section in the middle of the mixing tank. The stirring shaft is then rapidly driven to rotate, causing the materials to fall from the screen plate and its own holes. During this fall, the materials are also struck by a chaff plate. Finally, the chaff plate is lowered appropriately to further mix the materials. This method employs sweeping, lifting, secondary sweeping, and stirring sequentially to rapidly mix the raw materials, improving mixing efficiency and greatly facilitating subsequent material use.

[0014] 2. This utility model, through the ingredient mixing component, allows the threaded column to be inserted into the threaded hole after mixing, and the connection is completed with the rotation of the stirring shaft. Then, the adjusting block continues to rotate, so that the interlaced through holes one and two are connected, so that the raw material falls onto the loading tray. Due to the fit between the pressure plate and the loading tray, excess raw material will be scraped to the rear by the scraper, ensuring the accuracy of material discharge and making it highly practical.

[0021] 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 specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a slow rebound foaming raw material premixing device.

[0024] Combination Figure 1-2 As shown, the present invention provides a slow rebound foaming raw material premixing device, comprising: a machine body assembly 100 and a batching assembly 200 disposed on the machine body assembly 100; the machine body assembly 100 includes a workbench 110, a fixing frame 120 mounted on the workbench 110, a conveyor belt 130 disposed on the workbench 110, a material tray 140 placed on the conveyor belt 130, and a filler strip 150 filling between the material trays 140. By placing the material trays 140 on the conveyor belt 130, the material trays 140 can carry a certain amount of mixed raw materials after continuously passing under the mixing tank 210, thereby facilitating subsequent use. The filler strip 150 serves a filling function to ensure that the material does not leak.

[0025] The batching assembly 200 includes a mixing tank 210 mounted on the body assembly 100, a stirring mechanism mounted on the mixing tank 210, and a discharge mechanism mounted at the bottom of the mixing tank 210. The stirring mechanism includes a guide frame 220 mounted on the top of the mixing tank 210, a motor 230 mounted inside the guide frame 220, lifting devices 240 connected to both sides of the motor 230, a stirring shaft 250 fixed to the drive end of the motor 230, a mixing screen 260 mounted in the middle of the stirring shaft 250, a mixing screen plate 270 hinged to the lower part of the stirring shaft 250, a fixing plate 280 fixed to the stirring shaft 250 and located below the mixing screen plate 270, a torsion spring shaft 281 mounted on the side of the fixing plate 280, and a torsion spring shaft 281 fixed to the torsion spring shaft 281. The feeding plate 290 on the mixing tank 210 can drive the stirring shaft 250 to rotate using the motor 230 during the process of feeding raw materials into the mixing tank 210. The mixing screen 260 sweeps and mixes the various raw materials, which then fall through the mixing screen 260. After the raw materials have completely landed on the mixing screen 270, the lifting device 240 extends upward, allowing the mixing screen 270 to pass over the diameter-changing section in the middle of the mixing tank 210. Then, the stirring shaft 250 is quickly driven to rotate, and the raw materials fall from the mixing screen 270 and its own holes. During the falling process, they are also struck by the feeding plate 290. Finally, the feeding plate 290 is appropriately lowered to mix the raw materials. This scheme uses sweeping, lifting, secondary sweeping, and stirring in sequence to fully mix the raw materials, which not only improves the mixing efficiency but also greatly facilitates the use of subsequent materials.

[0026] Specifically, the feature is that the inner diameter of the lower part of the mixing tank 210 is smaller than the diameter of the upper part of the mixing tank 210, which allows the mixing mesh plate 270 to carry the raw material and move upward to the variable diameter position of the mixing tank 210, after which the raw material will naturally slide to both sides.

[0027] It should be noted that both the mixing mesh 260 and the mixing mesh 270 allow raw materials to pass through, but when the rotation force is small or the mesh is stationary, materials can be piled up on them, with only a small amount falling off. The raw material particles pile up together and generate lateral mutual compression, while static friction is generated in the vertical direction.

[0028] Furthermore, the discharge mechanism includes a pressure spring 310 fixed to the bottom of the mixing tank 210, a pressure plate 320 connected to the bottom of the pressure spring 310, a sealing sleeve 330 disposed on the outside of the pressure spring 310, an adjusting block 340 fitted in the middle of the pressure plate 320, an insertion hole 350 opened in the middle of the adjusting block 340 for the stirring shaft 250 to be inserted, a threaded post 360 fixed to the bottom of the insertion hole 350, a threaded hole 370 opened at the bottom end of the stirring shaft 250, and a threaded hole 370 opened in the adjusting block 340. The through holes 380 on both sides and the through holes 390 at the bottom of the mixing tank 210 and the pressure plate 320 respectively allow the threaded column 360 to be inserted into the threaded hole 370 after mixing is completed. The connection is completed by rotating the stirring shaft 250. Then, the adjusting block 340 is rotated to make the intersecting through holes 380 and 390 connect. This allows the raw material to fall onto the loading tray 140. Due to the fit between the pressure plate 320 and the loading tray 140, excess raw material will be scraped to the rear by the scraper 321, ensuring the accuracy of discharge and making it highly practical.

[0029] Specifically, the first through hole 380 and the second through hole 390 are staggered, so that the discharge can be controlled by rotating the adjusting block 340.

[0030] Furthermore, the pressure plate 320 has chamfers on both sides and a scraper 321 at the bottom. The chamfers can avoid obstructing the material tray 140 and the filler strip 150 below, and can be self-adaptively pressed onto the material tray 140 in conjunction with the pressure spring 310.

[0031] The working principle and usage process of this utility model are as follows: First, the raw materials are put into the mixing tank 210. During the feeding process, the motor 230 drives the stirring shaft 250 to rotate, and the mixing screen 260 sweeps and mixes the various raw materials. Then, the raw materials fall through the mixing screen 260. After the raw materials have completely landed on the mixing screen 270, the lifting device 240 extends upward, so that the mixing screen 270 passes over the diameter-changing part in the middle of the mixing tank 210. Then, the stirring shaft 250 is quickly driven to rotate, and the raw materials fall from the mixing screen 270 and its own holes. During the falling process, they are also struck by the discharge plate 290. Finally, appropriate... The discharge plate 290 is lowered to mix the raw materials. The raw materials are thoroughly mixed by sweeping, lifting, secondary sweeping, and stirring in sequence. When discharge is required, the stirring shaft 250 is driven to fall, and the motor 230 drives the threaded post 360 to insert into the threaded hole 370 to complete the connection. Then, the adjusting block 340 is driven to rotate, so that the interlaced through holes 1 380 and 2 390 are connected, so that the raw materials fall onto the loading tray 140. Due to the contact between the pressure plate 320 and the loading tray 140, the excess raw materials are scraped to the rear by the scraper 321.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
