DETAILED DESCRIPTION

[0015] In order to more clearly illustrate the above-mentioned purposes, features and advantages of the utility model, the following will be further explained to the utility model by combining with drawings and embodiments.It needs to be explained that, in the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0016] In the following description, many specific details are set forth in order to provide a thorough understanding of the utility model, however, the utility model can also be implemented in other ways different from the description herein, therefore, the utility model is not limited to the specific embodiments disclosed in the following description.

[0017] Embodiment 1, as Figure 1 、 Figure 2As shown, the embodiment aims to provide an automatic injection molding plastic bucket raw material blending device to realize automatic weighing and automatic blending of injection molding plastic bucket raw materials, for this purpose, the automatic injection molding plastic bucket raw material blending device provided by the embodiment includes a rack 1, a base material tank 2 arranged on the rack 1 and an auxiliary material tank 3 arranged outside the base material tank 2. The number of auxiliary material tanks 3 is determined according to the formula. Generally speaking, there are two or three kinds of auxiliary materials for plastic buckets. Therefore, the number of auxiliary material tanks 3 is set to two or three. The main purpose of the rack 1 is to raise the height of the base material tank 2 and the auxiliary material tank 3.

[0018] In the embodiment, the base material tank 2 and the auxiliary material tank 3 each include a tank body 4 and a drive motor 43 arranged on the top of the tank body 4. The power end of the drive motor 43 is connected with an auger shaft 44, the auger shaft 44 is arranged through the tank body 4, the bottom of the tank body 4 is provided with a discharge port 42, the auger shaft 44 is arranged to extend out of the discharge port 42, and the part of the auger shaft 44 extending into the tank body 4 is sleeved with a spiral blade 45. Since the amount of material rotated out by the spiral blade 45 each time is consistent, in the case that the volumes of the base material tank 2 and the auxiliary material tank 3 are consistent, the ratio of materials can be adjusted by controlling the rotating speed of the drive motor 43, and in the case that the volumes of the base material tank 2 and the auxiliary material tank 3 are inconsistent, the ratio of materials can be adjusted by controlling the volume ratio of the base material tank 2 and the auxiliary material tank 3 (in the case that the ratio between the spiral blade 45 and the tank body 4 is consistent). In this way, the accurate proportioning of materials can be realized without using a weight sensor.

[0019] Of course, the tank body 4 needs to be fed, so a feeding port 41 is arranged on the top of the tank body 4. In this way, after the material enters the tank body 4, it is discharged by the spiral blade 45 under the action of the spiral blade 45, and the amount of discharged material can be effectively controlled. In the embodiment, the ratio of materials is adjusted by controlling the rotating speed of the drive motor 43.

[0020] Considering that the injection molding plastic does not need to mix for too long time, because it does not need to react, for this, the stirring is relatively simple, using this feature, in order to realize the one-time material mixing, in the embodiment, the material collecting hopper 5 is also arranged on the rack 1, the material collecting hopper 5 is arranged below the tank body 4, the caliber of the material collecting hopper 5 meets that all the tank bodies 4 are above, the mixing pipe 51 is arranged in the middle of the material collecting hopper 5, the auger shaft 44 of the base material tank 2 extends into the mixing pipe 51, the distribution cone 46 and the material collecting bowl 47 are sleeved on the auger shaft 44 of the base material tank 2, the distribution cone 46 is arranged in the shape of an umbrella, and the material collecting bowl 47 is arranged in the shape of a bowl, the distribution cone 46 is arranged in the material collecting bowl 47, and the distribution cone 46 is arranged close to the top of the material collecting bowl 47, and the material collecting bowl 47 is arranged on the bottom of the material collecting bowl 47. The material collecting bowl 47 is arranged on the bottom of the material collecting bowl 47. In the embodiment, the fixed arc plate 471 is welded or bolted on the side wall of the auger shaft 44, and the fixed arc plate 471 is fixed between the inner wall of the material collecting bowl 47. In this way, the materials falling from the base material tank 2 and the auxiliary material tank 3 enter the mixing pipe 51, and the materials are thrown by the distribution cone 46 due to the rotation of the auger shaft 44. After touching the inner wall of the material collecting bowl 47, since they are all plastic materials, they have a certain elasticity, so that they will produce mixing during the collision. At the same time, due to the arrangement of the fixed arc plate 471, the direction of some materials will be deviated during rotation, so as to achieve better mixing. It needs to be explained here that since the amount of base material is large and closest to the mixing pipe 51, the driving motor 43 of the auxiliary material tank 3 needs to be turned on first when starting, and the base material tank 2 is controlled to open after the auxiliary material is controlled to fall, so as to ensure that the initial base material can also be mixed with auxiliary material.

[0021] In order to better utilize the centrifugal force and ensure that the materials can be quickly mixed, in the embodiment, a guide plate 52 is arranged in the material collecting hopper 5, the guide plate 52 is inclined downward from the edge of the material collecting hopper 5 to the direction of the mixing pipe 51, and the guide plate 52 is arranged below the tank body 4 of the auxiliary material tank 3. In this way, the arrangement of the guide plate can accelerate and ensure the flow of the auxiliary material.

[0022] In order to better mix, in the embodiment, the guide plate 52 extends to the center of the mixing pipe 51. The purpose of the guide plate 52 extending to the center is two-fold. One is to ensure that the material falls under the change of centrifugal force, because the size of the centrifugal force is related to the radius, so that the centrifugal force is gradually increased during the movement of the material from the center of the distribution cone 46 to the outside, and the stress state is better than that of directly falling on the edge, which can achieve better mixing purpose. At the same time, due to the shielding of the guide plate 52, part of the base material will be mixed with the auxiliary material without entering the mixing pipe 51.

[0023] In order to better disperse and mix the material, a material guide groove 461 is arranged on the top surface of the material distribution cone 46, and the material guide groove 461 is arranged diverging outward along the center of the material distribution cone 46. Since the material guide groove 461 divides the material into several branches, after colliding with the material collecting bowl 47, the material is more dispersed under the effect of elasticity, and is more convenient to mix, so as to ensure that the mixing is completed in the process of rapid falling.

[0024] Through the above arrangement, automatic quantitative and mixing are effectively realized, and the labor intensity of the workers is reduced.

[0025] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made on the basis of the technical essence of the present application to the above embodiments shall still fall within the protection scope of the present application.
