Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0019] like Figure 1-3As shown: This embodiment provides a feeding device for coating preparation, including a hopper 100. The hopper 100 is mounted on a frame, which is located near the feeding area of ​​the device to be fed. The size of the hopper 100 can be designed according to the amount of material to be fed and the size of the device to be fed. Figure 1 As shown, the hopper 100 is designed as a frustum-shaped cylindrical structure with a larger opening at the top than at the bottom. A feeding mechanism 200 is connected to the lower part of the hopper 100. The feeding mechanism 200 includes a pushing component 210 and a driving component 220. The driving component 220 is a servo motor. The end of the output shaft of the driving component 220 is connected to the fixed shaft 212 through a bearing transmission. The driving component 220 drives the pushing component 210 to push the material in opposite directions. This utility model can achieve the opposite movement of the material by driving the pushing component 210 through the driving component 220, realizing the efficient feeding operation of material diversion. It solves the problem that the traditional feeding mechanism 200 has only one feeding port, resulting in low feeding efficiency and inability to meet the problem of simultaneous feeding operations at different positions. It greatly improves the feeding range and feeding efficiency, and makes the operation more convenient and efficient.

[0020] According to one embodiment of the present invention, such as Figure 1-3 As shown, the feeding assembly 210 includes a guide cylinder 211 disposed at the lower part of the hopper 100 and connected thereto. A plane perpendicular to the axis of the guide cylinder 211, located on the axis of the hopper 100, divides the guide cylinder 211 into two parts. A fixed shaft 212 is provided at the end of the output shaft of the drive unit 220. A first spiral conveying blade 213 is provided on the fixed shaft 212 on one side of the plane perpendicular to the axis of the guide cylinder 211, located on the axis of the hopper 100. A second spiral conveying blade 214 is provided on the fixed shaft 212 on the other side of the plane. The spiral directions of the first spiral conveying blade 213 and the second spiral conveying blade 214 are opposite. This utility model can drive the fixed shaft 212 and the first spiral conveying blade 213 and the second spiral conveying blade 214 on the outside of the fixed shaft 212 to rotate synchronously in opposite directions through the rotation of the output shaft of the drive component 220, thereby realizing the back-to-back conveying operation of the material falling through the hopper, which greatly improves the material feeding efficiency and makes the operation more convenient and efficient.

[0021] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the hopper 100 has a structure where the upper opening is larger than the lower opening. This is to facilitate the formation of a certain slope, so that the material can slide smoothly under its own weight, making the operation safer and more convenient.

[0022] A connecting pipe 300 is provided between the lower part of the silo 100 and the guide cylinder 211, which is connected to the silo 100. The present invention can realize the connection between the silo 100 and the guide cylinder 211 through the connecting pipe 300, and can also play the role of temporary transfer and storage of materials, thereby improving the storage capacity of the silo 100 to a certain extent.

[0023] According to another embodiment of the present invention, such as Figure 1 and Figure 3 As shown, both ends of the guide cylinder 211 are provided with discharge pipes 215 connected to it. The discharge pipes 215 can be set as needed, with at least 2, or 4, 6 or 8. The selection can be made according to the location where the material needs to be fed. The discharge pipes 215 can realize the smooth and efficient discharge of the material in the guide cylinder 211, making the operation more convenient and efficient.

[0024] How to use this utility model:

[0025] First, it needs to be clarified that the feeding device involved in this utility model is mainly used for efficient forced feeding of various powders, granular solid materials, or colloidal materials. This utility model takes the feeding of paint powders or granular materials as an example to describe its usage method in detail. When it is necessary to feed powder, the output shaft of the drive motor is started to rotate while the material to be fed is introduced into the feeding bin 100. By starting the output shaft of the servo motor to rotate, the material falling through the bin 100 is conveyed in opposite directions along with the fixed shaft 212 and the first and second spiral conveying blades outside the fixed shaft 212. This greatly improves the feeding range and efficiency. This utility model can drive the pushing component 210 through the drive component 220 to achieve the opposite movement of the material, realizing efficient feeding of the material. This solves the problem that the traditional feeding mechanism 200 has only one feeding port, resulting in low feeding efficiency and inability to meet the simultaneous feeding operation at different positions.

[0026] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
