[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1 to 3 The present invention provides a technical solution: a batching device for polyurethane material production, including a batching tank 1, a mixing component 200 for batching and mixing raw materials is installed inside the batching tank 1, and a feeding component 300 is installed on the top of the batching tank 1.
[0025] By using the mixing tank 1 and the mixing assembly 200 in combination with the stirring plate 203, scraper 210 and crossbar 211, the raw materials required for polyurethane material production can be effectively scraped off the raw materials adhering to the inner wall of the mixing tank when mixing and batching them. This effectively avoids the situation where the raw materials remain on the inner wall of the mixing tank, which may affect the accuracy of the batching. In addition, the mixing effect of the raw materials is relatively good, which improves the practicality of the batching device for polyurethane material production.
[0026] In this embodiment, the mixing component 200 is a structure for mixing raw materials.
[0027] like Figure 1 , Figure 2 and Figure 3As shown, the mixing component 200 includes a first motor 201 fixed to the top of the mixing tank 1. A stirring rod 202 is fixed to the output shaft of the first motor 201. Multiple stirring plates 203 are fixed to the outside of the stirring rod 202. Two connecting rods 204 are fixed to both the left and right sides of the stirring rod 202. A telescopic rod 205 is fixed inside the connecting rod 204. A spring 206 is fixed inside the connecting rod 204. There is a mounting groove 207 on the opposite side of the left and right connecting rods 204. A sliding block 208 is slidably connected inside the mounting groove 207. A moving block 209 is fixed between the left sides of the two sliding blocks 208 on the left and between the right sides of the two sliding blocks 208 on the right. A scraper 210 is fixed to the opposite side of the two moving blocks 209. Multiple crossbars 211 are fixed to the opposite side of the two moving blocks 209.
[0028] It should be noted that the bottom end of the stirring rod 202 passes through the mixing tank 1 and is rotatably connected to the mixing tank 1 through a bearing, ensuring that the stirring rod 202 can rotate stably and effectively in its original position.
[0029] In addition, the telescopic rod 205 is fixed inside the mounting groove 207 to ensure that the telescopic rod 205 can be fixed. The spring 206 is located on the outside of the telescopic rod 205. The opposite sides of the left and right springs 206 are fixed to the sliding block 208 to ensure that the elastic force of the spring 206 can act on the sliding block 208, so that the scraper 210 is in close contact with the inner wall of the mixing tank 1.
[0030] In addition, discharge pipes 4 are fixed on both the left and right sides of the mixing tank 1 for discharging the mixed raw materials. A vibration motor 5 is fixed at the bottom of the mixing tank 1. The vibration motor 5 causes slight vibration to the mixing tank 1, thereby making the mixing efficiency of the raw materials higher. Multiple support seats 6 are fixed at the bottom of the mixing tank 1 to make the mixing tank 1 more stable.
[0031] In this embodiment, the feeding component 300 is a structure used to feed in the raw materials.
[0032] like Figure 1 As shown, the feeding assembly 300 includes four connecting columns 301 fixed to the top wall of the mixing tank 1. Two feeding pipes 302 are fixed to the top of the mixing tank 1. A buffer cylinder 303 is fixed to the top of the feeding pipes 302. A protective cover 304 is hinged to the top of the buffer cylinder 303. A triangular prism 305 is fixed between the bottom ends of the two connecting columns 301 on the left and between the bottom ends of the two connecting columns 301 on the right.
[0033] It should be noted that the front and back sides of the triangular prism 305 do not contact the inner wall of the mixing tank 1, effectively preventing the triangular prism 305 from affecting the rotation of the scraper 210. The triangular prism 305 can initially disperse the raw materials entering through the feed pipe 302, which facilitates the subsequent mixing of the raw materials.
[0034] The working principle of the above embodiments is as follows:
[0035] In use, the raw materials required for the production of polyurethane material are added into the mixing tank 1 through the buffer cylinder 303 and the feed pipe 302. The triangular prism 305 can also be used to initially disperse the raw materials. Then, the first motor 201 is turned on, which drives the stirring rod 202 to rotate in place, thereby driving the stirring plate 203 and the connecting rod 204 to rotate. During use, the spring 206 is in a compressed state, so the sliding block 208, the moving block 209 and the scraper 210 are in close contact with the inner wall of the mixing tank 1 by the elastic force of the spring 206. Thus, the scraper 210 can effectively scrape off the raw materials adhering to the inner wall of the mixing tank 1. Under the action of the stirring plate 203, the crossbar 211 and the vibrating motor 5, the mixing effect of the raw materials can be effectively achieved.
[0036] Compared with existing technologies, this batching device for polyurethane material production, through the coordinated use of the batching tank 1, the mixing component 200, the stirring plate 203, the scraper 210, and the crossbar 211, can effectively scrape off the raw materials adhering to the inner wall of the batching tank when mixing the raw materials required for polyurethane material production. This effectively avoids the situation where raw materials remain on the inner wall of the batching tank, which would affect the accuracy of batching. Furthermore, the mixing effect of the raw materials is relatively good, improving the practicality of the batching device for polyurethane material production and solving the problem of low practicality of existing batching devices for polyurethane material production.
[0037] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The provision of external power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
