Description

Technical Field

[0001] This utility model relates to the field of metal powder coating technology, specifically to a resin and metal powder mixing device. Background Technology

[0002] In modern chemical engineering, materials science, and manufacturing, the mixing technology of resins and metal powders is widely used in the manufacture of high-performance composite materials, coatings, adhesives, and functional plastics. Currently, the mixing of resins and metal powders involves directly adding both to a mixing device for stirring. If the temperature in the mixing device is too high, the metal powder absorbs heat, reducing its fluidity and causing the material to settle at the bottom of the device. If the temperature is too low, the material will stick together, compromising the uniformity and stability of the resulting mixture.

[0003] A search of the China Patent Network revealed a patent document with publication number CN 217093152 U, which discloses a metal powder coating mixing and stirring device. This device uses a hollow spiral stirring rod and, depending on the situation, inputs a heat source or a cold source to regulate the temperature inside the tank. This effectively prevents excessively high or low internal temperatures from causing deposition or adhesion, thus improving performance and practicality.

[0004] However, when the spiral stirring rod rotates, it only stirs the resin and metal powder mixture at the same height. Due to sedimentation, the resin and metal powder will be in the lower layer, resulting in an uneven mixture between the upper and lower layers. Similarly, temperature adjustment of the mixture requires the transfer between the mixtures. The temperature of the mixture far from the spiral stirring rod takes a long time to adjust, which may even lead to poor quality of the prepared coating. Therefore, a resin and metal powder stirring device is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a resin and metal powder mixing device to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a resin and metal powder mixing device, comprising an outer cylinder, a temperature control component is assembled at the center of the inner part of the outer cylinder, and constraint cylinders fixed to the lower inner wall of the outer cylinder are provided on both sides of the temperature control component. Each set of constraint cylinders is rotatably equipped with an auger shaft for conveying materials into the temperature control component. A heat source is provided at the top of the outer cylinder, and a cold source is assembled on one side of the heat source. The bottom ends of the heat source and the cold source are connected to branch pipes for conveying hot and cold liquids into the temperature control component.

[0007] The temperature control component includes a frame fixed to the inner wall of the curved surface of the outer cylinder. The front and rear inner walls of the frame are each fixed with a symmetrical set of first baffles. Below each set of first baffles, there are second baffles fixed to the left and right inner walls of the frame. At the bottom of each set of first baffles, there are a number of baffles fixed to the top of the second baffles. Two sets of guide pipes connected to branch pipes pass through the multiple sets of baffles. The ends of the two sets of branch pipes are connected to a main outlet pipe extending to the outer side of the bottom of the outer cylinder.

[0008] As a preferred technical solution, the two sets of first spoilers of the same height are inclined towards the middle, and the first section of the two sets of first spoilers close to each other constitutes the first discharge port. The first spoilers on the left and right sides are symmetrically arranged along the central axis of the frame, and the guide pipe is inserted between the first spoiler and the second spoiler in a folded-back shape.

[0009] As a preferred technical solution, the second spoiler is convex in the middle, and the two ends of the second spoiler and the inner wall of the frame form a second discharge port.

[0010] As a preferred technical solution, the outer walls of both the heat source and the cold source are equipped with positioning frames fixed to the top of the outer cylinder, and the branch pipe is equipped with a solenoid valve for selecting the opening and closing of the heat source and the cold source.

[0011] As a preferred technical solution, a top plate is fixed inside the outer cylinder near the top position. The top of the top plate has a channel for the top of two sets of auger shafts to pass through, and the channel is connected to the outer wall of the auger shafts by bearings. The top of the two auger shafts is fixed with pulleys, and belts are sleeved on the outer walls of the two sets of pulleys. A drive motor for driving one set of auger shafts to rotate is installed on the top of the outer cylinder.

[0012] As a preferred technical solution, the top edge of the constraint cylinder is provided with a guide frame extending to the top of the frame, and the bottom edge of the constraint cylinder is provided with an inlet.

[0013] As a preferred technical solution, the top of the outer cylinder is provided with a feed pipe on the side of the drive motor, and the feed pipe extends to the bottom of the top plate.

[0014] As a preferred technical solution, the bottom of the frame is in a non-contact state with the lower inner wall of the outer cylinder, and the inner bottom of the outer cylinder is in a low-lying position at the contact point with the constraint cylinder.

[0015] In summary, the present invention has the following main advantages:

[0016] This invention uses an auger shaft to make the material at the bottom surge upwards, and the frame makes the material flow in a zigzag trajectory, which makes the metal powder and resin mix more thoroughly. At the same time, the baffles and baffles inside the frame extend the trajectory of the material, thereby increasing the time for heat exchange with the liquid inside the guide tube. This allows for rapid and stable changes in the temperature of the material, resulting in a higher quality final mixed material. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The embodiments of this utility model will be described below based on its overall structure.

[0027] A resin and metal powder mixing device, such as Figures 1 to 6As shown, it includes an outer cylinder 100, a temperature control component 160 is installed at the center of the outer cylinder 100, and constraint cylinders 130 fixed to the lower inner wall of the outer cylinder 100 are provided on both sides of the temperature control component 160. Each set of constraint cylinders 130 is rotatably equipped with an auger shaft 131 for conveying materials into the temperature control component 160. A heat source 140 is provided at the top of the outer cylinder 100, and a cold source 150 is installed on one side of the heat source 140. The bottom ends of the heat source 140 and the cold source 150 are connected to branch pipes 170 for conveying hot and cold liquids into the temperature control component 160.

[0028] The temperature control assembly 160 includes a frame 161 fixed to the inner wall of the curved surface of the outer cylinder 100. A plurality of symmetrical first baffles 162 are fixed to the front and rear inner walls of the frame 161. A second baffle 164 is fixed to the left and right inner walls of the frame 161 below each set of first baffles 162. A plurality of baffles 163 are fixed to the top of the second baffles 164 at the bottom of each set of first baffles 162. Two sets of guide pipes 171 connected to branch pipes 170 pass through the multiple sets of baffles 163. The ends of the two sets of branch pipes 170 are connected to a main outlet pipe 172 extending to the outer side of the bottom of the outer cylinder 100.

[0029] Two sets of first spoilers 162 of the same height are inclined towards the middle, and the first section of the two sets of first spoilers 162 that are close together constitutes the first discharge port. The first spoilers 162 on the left and right sides are symmetrically arranged along the central axis of the frame 161. The guide pipe 171 is folded back and inserted between the first spoiler 162 and the second spoiler 164.

[0030] The second spoiler 164 is convex in the middle, and the two ends of the second spoiler 164 form a second discharge port with the inner wall of the frame 161. Multiple sets of baffles 163 located on the top of the second spoiler 164 are staggered and contact the front and rear inner walls of the frame 161.

[0031] The auger shaft 131 rotates and cooperates with the constraint cylinder 130, causing the material in the lower layer of the outer cylinder 100 to flow upward. The material eventually overflows from the top of the constraint cylinder 130 and enters the frame 161. It flows obliquely towards the center along the first baffle 162, flows through the first discharge port to the second baffle 164, and flows along the second baffle 164 to both ends. The baffle plate 163 constrains the material, causing it to flow in a zigzag trajectory on the second baffle 164 until it flows from the second discharge port to the lower first baffle 162, repeating the above trajectory flow until it flows back to the lower layer of the outer cylinder 100, so that the material is stirred in this up-and-down cycle.

[0032] The heat source 140 or cold source delivers high-temperature or low-temperature liquids to the two sets of guide pipes 171 through the branch pipe 170, heating or cooling the material flowing through the first baffle 162 and the second baffle 164. The baffle plate 163 provides sufficient time for the material to change temperature, effectively preventing sedimentation or adhesion caused by excessively high or low temperatures. The up-and-down circulation stirring method results in a high quality of the final prepared material.

[0033] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The outer walls of both the heat source 140 and the cold source 150 are fitted with positioning brackets fixed to the top of the outer cylinder 100, and the branch pipe 170 is equipped with a solenoid valve that selects the opening and closing of the heat source 140 and the cold source 150.

[0034] The positioning frame supports the weight of the heat source 140 and the cold source 150, making them stably positioned on top of the outer cylinder 100. The solenoid valve can select the opening and closing of the heat source 140 and the cold source 150.

[0035] Please refer to this carefully. Figure 4 and Figure 5 The top plate 180 is fixed inside the outer cylinder 100 near the top. The top of the top plate 180 has a channel for the top of two sets of auger shafts 131 to pass through. The channel is connected to the outer wall of the auger shafts 131 by bearings. The top of the two auger shafts 131 is fixed with pulleys 132. The outer wall of the two sets of pulleys 132 is fitted with belts 133. The top of the outer cylinder 100 is equipped with a drive motor 120 that drives one of the auger shafts 131 to rotate.

[0036] The output end of the drive motor 120 rotates, and the belt causes the two sets of auger shafts 131 to rotate synchronously inside the constraint cylinder 130, causing the material located in the lower layer of the outer cylinder 100 to surge upward, achieving the effect of fully heating and mixing the material.

[0037] Please refer to this carefully. Figure 4 and Figure 5 The top edge of the constraint cylinder 130 is provided with a guide frame 134 extending above the frame 161, and the bottom edge of the constraint cylinder 130 is provided with an inlet 135.

[0038] The material inside the outer cylinder 100 is allowed to enter the confinement cylinder 130 through the inlet 135, and the material inside the confinement cylinder 130 can be accurately entered into the frame 161 through the guide frame 134, thereby achieving the function of heating or cooling.

[0039] Please refer to this carefully. Figure 1 The top of the outer cylinder 100 is provided with a feed pipe on one side of the drive motor 120, and the feed pipe extends to the bottom of the top plate 180.

[0040] The metal powder and resin can be conveyed into the outer cylinder 100 for heating and mixing using the feed pipe.

[0041] Please refer to this carefully. Figure 2 The bottom of the frame 161 is not in contact with the lower inner wall of the outer cylinder 100, and the inner bottom of the outer cylinder 100 is in a low-lying position at the contact point with the constraint cylinder 130.

[0042] This allows the mixed metal powder and resin to flow into the confinement cylinder 130, enter and flow upward to complete the mixing and uniform heating.

[0043] A bracket 110 is welded to the bottom of the outer cylinder 100.

[0044] It provides a stabilizing effect on the outer cylinder 100 and facilitates the discharge of high-temperature or low-temperature liquids from the main outlet pipe 172.

[0045] In use, the auger shaft 131 rotates and cooperates with the constraint cylinder 130, causing the material in the lower layer of the outer cylinder 100 to flow upward. The material eventually overflows from the top of the constraint cylinder 130 and enters the frame 161. It flows obliquely towards the center along the first baffle 162, flows through the first discharge port to the second baffle 164, and flows along the second baffle 164 to both ends. The baffle plate 163 constrains the material, causing it to flow in a zigzag trajectory on the second baffle 164 until it flows from the second discharge port to the lower first baffle 162, repeating the above trajectory flow until it flows back to the lower layer of the outer cylinder 100, so that the material is stirred in this up-and-down cycle.

[0046] A heat source 140 or a cold source delivers high-temperature or low-temperature liquids to two sets of guide pipes 171 via a branch pipe 170. This heats or cools the material flowing through the first baffle 162 and the second baffle 164. The baffle plate 163 provides sufficient time for the material to change its temperature, effectively preventing sedimentation or adhesion caused by excessively high or low temperatures. The up-and-down circulation stirring method results in a high-quality final product. Any parts of this device not described herein are the same as or can be implemented using existing technologies.
