[0022] Embodiment 1: This embodiment is intended to help solve the problem that most of the graded mixing equipment may cause blockage during discharging after mixing, due to the relatively fine powder, resulting in uneven discharging and subsequent powder pressing, which may also cause problems. Please refer to Figure 1-Figure 4A graded mixing and conveying powder pressing machine includes a work surface 110, a powder pressing device 120 and a conveying device 130. The powder pressing device 120 is installed on the upper side of the work surface 110, and the conveying device 130 is installed on the upper side of the work surface 110. The powder pressing device 120 is installed adjacent to the upper side of the conveying device 130. The movable end of the powder pressing device 120 is in intermittent contact with the rotating end of the conveying device 130.

The limiting device 170 is used to quantify each formed powder cake. The powder pressing device 120 is a device for pressing materials into granules. It is usually used in the fields of powder metallurgy, chemical industry, pharmaceuticals, food processing, etc. The specific operation process is to add the material into the mold cavity in the powder pressing machine, and then press the material into the desired shape and size by applying pressure. The powder pressing device 120 is usually composed of a main machine, a mold, a control system, etc. The powder pressing device 12 is a common device, and its specific model, working principle and usage are well known to technical personnel in this field, so no further details will be given here.
[0023] The mixing barrel 150 is configured as a circular cylinder, and an inclined block 151 is installed inside the mixing barrel 150. The cross-sectional shape of the inclined block 151 is configured as a circle, and a flow hole 152 is opened in the middle of the inclined block 151. The mixing barrel 150 is divided into a first mixing layer 153 and a second mixing layer 154 by the action of the inclined block 151. A feed port 155 is installed on the upper side of the mixing barrel 150, and two feed ports 155 are provided.
[0024] A support frame 180 is installed on the bottom side of the mixing barrel 150. There are two support frames 180. One end of the two support frames 180 is connected to the work surface 110, and the other end of the two support frames 180 is connected to the bottom side of the mixing barrel 150. A discharge port 181 is opened on the bottom side of the mixing barrel 150. The mixing barrel 150 is installed adjacent to the upper side of the conveying device 130.
[0025] A rotating motor 141 is installed on the upper side of the mixing barrel 150, and a groove 142 is provided on the output shaft of the rotating motor 141, and the groove 142 is arranged as a curved groove, and the groove 142 is vertically arranged on the surface of the output shaft of the rotating motor 141, and the stirring rod 140 is plugged into the output shaft of the rotating motor 141, and a protrusion 143 is installed on the side of the stirring rod 140, and the protrusion 143 and the groove 142 are movably matched. In specific implementation, since the protrusion 143 and the groove 142 are movably matched, when the output shaft of the rotating motor 141 rotates, the groove 142 pushes the protrusion 143, and since the groove 142 is arranged as a curved groove, the stirring rod 140 can move up and down, so as to better mix the powder.
[0026] The stirring rod 140 passes through the mixing barrel 150 and reaches the first mixing layer 153. A stirring blade is sleeved on the outer side of the stirring rod 140. The stirring blades include a first group of blades 190 and a second group of blades 191. The diameter of the first group of blades 190 is larger than that of the second group of blades 191. The inclination angle of the first group of blades 190 is about 5-20 degrees. A spiral rod 192 is integrated at the end of the stirring rod 140.
[0027] In the present embodiment, during use, a spiral end 163 is installed at the bottom end of the stirring rod 140. When the powder flows, the spiral end 163 rotates and cooperates with the discharge port 181, so that the powder can be turned over, and the flow of the powder can be accelerated to prevent the powder from blocking the discharge port 181. By cooperating with the turning component 160 and the inside of the mixing barrel 150, the L-shaped rod 161 slides and fits with the inner wall of the mixing barrel 150 to prevent the powder from being mixed insufficiently. The present solution has a simple structure and is easy to operate. It can accelerate the flow of the powder and prevent the powder from blocking the discharge port 181.
[0028] Example 2: This example is intended to promote the solution to the problem of uneven powder placement and waste. This example is an improvement made on the basis of Example 1. For details, please refer to Figure 1 - Figure 4 The bottom side of the mixing barrel 150 is arranged in a fan shape, and the flipping assembly 160 includes an L-shaped rod 161, an inclined rod 162, a spiral end 163 and a vertical rod 164. The vertical rod 164 is inserted into the bottom side of the stirring rod 140, and the L-shaped rod 161 is located on the side of the vertical rod 164. One end of the L-shaped rod 161 is slidably fitted with the inner wall of the mixing barrel 150, and the inclined rod 162 is connected to the bottom end of the L-shaped rod 161. The inclined rod 162 is fitted with the inner bottom surface of the mixing barrel 150, and the spiral end 163 is installed at the end of the inclined rod 162. The spiral end 163 is movably matched with the discharge port 181. The L-shaped rod 161, the inclined rod 162, the spiral end 163 and the vertical rod 164 are integrated.
[0029] The conveying device 130 is configured as a conveying belt, and a pressing mold 210 is arranged on the conveying belt surface of the conveying belt. There are a plurality of pressing molds 210, and the plurality of pressing molds 210 are arranged on the conveying belt surface at intervals. When the pressing mold 210 reaches the bottom side of the rod plate 172, the weight of the powder on the rod plate 172 is greater than the weight 173, and the powder falls onto the surface of the pressing mold 210. Since the amount of powder flow is fixed, the tilting time of the rod plate 172 can be adjusted according to the weight of the weight, so that the powder falls onto the surface of the pressing mold 210.
[0030] The limiting device 170 includes a support rod 171, a rod plate 172, a weight 173, and a connecting rod 174. There are two support rods 171, and the two support rods 171 are installed on the bottom side of the mixing barrel 150. The rod plate 172 is hinged between the two support rods 171, and the connecting rod 174 is installed at the end of the rod plate 172. The weight 173 is sleeved on the outside of the connecting rod 174, and the rod plate 172 is located on the bottom side of the discharge port 181.
[0031] In this embodiment: when in use, the mixed powder is dropped onto the surface of the rod plate 172 through the mixing barrel 150. Since the weight 173 is installed above the rod plate 172, when the weight of the powder is less than the weight of the weight 173, the rod plate 172 does not move. When the weight of the powder is greater than the weight of the weight 173, the rod plate 172 is tilted so that the powder falls into the inside of the pressing mold 210, thereby quantifying the powder. The weight of the weight 173 can be replaced. By replacing the weight 173 with different weights, the quantification of the powder is also different. This solution has a simple structure and is easy to operate, and can quantify the powder.

Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
