Description

Technical Field

[0001] This utility model relates to the field of coating powder production, specifically a raw material proportioning device for coating powder production and synthesis. Background Technology

[0002] The raw material proportioning device for coating powder production is one of the core pieces of equipment in the production process. The performance of coating powder is highly dependent on the precise proportion of raw materials. Precise proportioning avoids waste caused by excessive or insufficient raw materials, and can significantly reduce production costs, especially for high-priced raw materials (such as special resins and additives).

[0003] In the prior art, patent application CN220968993U discloses an automatic raw material proportioning device for powder coating production, including a base and a mixing tank. The mixing tank is fixedly installed at the top of the base, and the bottom of the mixing tank is connected to a servo motor a. The servo motor a is connected to gear a, and gear a is connected to gear b. Gear b is connected to a rotating shaft located inside the mixing tank. The bottom of the mixing tank is provided with a bottom cover, and the top of the mixing tank is connected to a sliding mounting seat. A weight sensor is installed at the top of the sliding mounting seat, and the top of the sliding mounting seat is connected to a hopper. A screw rod is provided inside the hopper, and the screw rod is connected to the servo motor b. This automatic raw material proportioning device for powder coating production can accurately control the amount of raw materials input by measuring the weight of the hopper in real time through the weight sensor during raw material proportioning, thereby improving the proportioning efficiency.

[0004] However, in the existing automatic raw material proportioning device for powder coating production, the installation of the sliding mounting base between the sliding mounting base and the mixing tank is achieved by two sets of clamping blocks, one inside and one outside, clamping onto the inner and outer walls of the mixing tank. In actual production, there will be errors in the spacing between the two sets of clamping blocks. When the spacing is too small, it will be impossible to install it onto the mixing tank, and when the spacing is too large, the sliding mounting base will not be installed securely. Utility Model Content

[0005] The purpose of this invention is to provide a raw material proportioning device for the production and synthesis of coating powders, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material proportioning device for the synthesis of coating powder, comprising: a mixing tank, a plurality of sliding mounting seats are movably installed on the top of the mixing tank, a weight sensor and a screw conveying mechanism are installed on the top of the sliding mounting seats, a fixed clamping plate is fixed at the bottom of the sliding mounting seats, a movable clamping plate is slidably connected to the bottom of the sliding mounting seats, a support plate is fixed on the surface of the sliding mounting seats, a screw hole is opened on the surface of the support plate, a screw rod is installed in the screw hole through a threaded connection, and a push plate is fixed at one end of the screw rod.

[0007] Preferably, a first anti-slip pad is fixed to one end of both the fixed clamp and the movable clamp that are close to each other.

[0008] Preferably, a groove is formed on the surface of the sliding mounting base, and a slider is slidably connected in the groove.

[0009] Preferably, a spring is provided in the slide groove, with one end of the spring fixed to the surface of the slider and the other end of the spring fixed to the surface of the support plate, and the spring is always in a compressed state.

[0010] Preferably, the movable clamping plate has an inverted "U" shaped plate structure, and the top of the movable clamping plate is fixed to the bottom of the slider.

[0011] Preferably, the push plate has a cylindrical structure, a second anti-slip pad is fixed on the surface of the push plate, and a boss is provided at one end of the movable clamping plate near the push plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The raw material proportioning device for coating powder production proposed in this utility model involves turning a screw to move a pusher plate closer to a fixed clamping plate, ultimately causing the first anti-slip pad fixed on the surface of the fixed clamping plate to press against the inner wall of the mixing tank. The pusher plate then pushes a movable clamping plate, pressing the first anti-slip pad fixed on the surface of the movable clamping plate against the outer wall of the mixing tank. Through the friction between the two sets of first anti-slip pads and the mixing tank, the sliding mounting base is installed on the mixing tank. This device can adjust the distance between the fixed clamping plate and the movable clamping plate through the threaded connection of the screw hole and the screw, overcoming possible errors during the production process.

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a raw material proportioning device for the synthesis of coating powder, comprising: a mixing tank 1, several sets of sliding mounting seats 2 are movably installed on the top of the mixing tank 1, a weight sensor 3 and a screw conveying mechanism 4 are installed on the top of the sliding mounting seats 2, a fixed clamping plate 5 is fixed at the bottom of the sliding mounting seats 2, a movable clamping plate 8 is slidably connected to the bottom of the sliding mounting seats 2, a support plate 9 is fixed on the surface of the sliding mounting seats 2, a screw hole 10 is opened on the surface of the support plate 9, a screw 11 is installed in the screw hole 10 by threaded connection, a push plate 12 is fixed at one end of the screw 11, a first anti-slip pad 13 is fixed at the close ends of the fixed clamping plate 5 and the movable clamping plate 8, a sliding groove 6 is opened on the surface of the sliding mounting seats 2, a slider 7 is slidably connected in the sliding groove 6, the movable clamping plate 8 has an inverted "U" shaped plate structure, and the top of the movable clamping plate 8 is fixed to the bottom of the slider 7.

[0021] In actual use, according to the types and quantities of raw materials required for the synthesis of coating powder, a corresponding number of sliding mounting seats 2 are installed on the top of the mixing tank 1. The top of the sliding mounting seat 2 is equipped with a weight sensor 3 and a screw conveyor mechanism 4. First, the weight of the screw conveyor mechanism 4 in the idle state is measured by the weight sensor 3. Then, various raw materials are added to each group of screw conveyor mechanisms 4. After adding enough, the various raw materials are conveyed into the mixing tank 1 through the screw conveyor mechanism 4. Then, the mixing of each raw material is achieved by the rotation of the stirring shaft and stirring rod in the mixing tank 1. When installing the sliding mounting base 2 onto the mixing tank 1, first rotate the screw 11. Under the action of the threaded connection between the screw 11 and the screw hole 10, the push plate 12 moves away from the fixed clamping plate 5. Then, move the movable clamping plate 8 away from the fixed clamping plate 5, creating a sufficient gap between the movable clamping plate 8 and the fixed clamping plate 5. Place the sliding mounting base 2 onto the mixing tank 1, with the fixed clamping plate 5 inside the mixing tank 1 and the movable clamping plate 8 outside the mixing tank 1. Then, reverse the screw 11, causing the push plate 12 to move closer to the fixed clamping plate 5. The directional movement eventually causes the first anti-slip pad 13 fixed on the surface of the fixed clamping plate 5 to press against the inner wall of the mixing tank 1. The push plate 12 pushes the moving clamping plate 8 so that the first anti-slip pad 13 fixed on the surface of the moving clamping plate 8 is pressed against the outer wall of the mixing tank 1. Through the friction between the two sets of first anti-slip pads 13 and the mixing tank 1, the sliding mounting seat 2 is installed on the mixing tank 1. The distance between the fixed clamping plate 5 and the moving clamping plate 8 can be adjusted by the threaded connection of the screw hole 10 and the screw 11, overcoming the errors that may occur during the production process.

[0022] Example 2: Based on Example 1, in order to prevent the threads between the screw hole 10 and the screw 11 from loosening, the push plate 12 is cylindrical, and a second anti-slip pad 14 is fixed on the surface of the push plate 12. A boss is provided at one end of the movable clamping plate 8 near the push plate 12.

[0023] When the pusher plate 12 pushes the movable clamping plate 8, pressing the first anti-slip pad 13 fixed on the surface of the movable clamping plate 8 against the outer wall of the mixing tank 1, the second anti-slip pad 14 is also pressed between the movable clamping plate 8 and the pusher plate 12. When the second anti-slip pad 14 is pressed, it will be compressed. The second anti-slip pad 14 is made of rubber material with good elasticity and relatively roughness. When it is pressed, the friction between the second anti-slip pad 14 and the movable clamping plate 8 is large, which can increase the damping required for the second anti-slip pad 14 to rotate in the opposite direction, thereby increasing the damping required for the pusher plate 12 and the screw 11 to rotate in the loosening direction. At the same time, the second anti-slip pad 14 generates a pushing force on the pusher plate 12 under its own elasticity. After this pushing force is transmitted to the screw 11, the thread between the screw hole 10 and the screw 11 is pressed, thereby increasing the friction between the screw threads of the screw hole 10 and the screw 11. Under the dual action, the thread between the screw hole 10 and the screw 11 is prevented from loosening.

[0024] Example 3: Based on Example 2, in order to achieve the pre-fixation of the sliding mounting base 2, a spring 15 is provided in the slide groove 6. One end of the spring 15 is fixed to the surface of the slider 7, and the other end of the spring 15 is fixed to the surface of the support plate 9. The spring 15 is always in a compressed state.

[0025] After the push plate 12 moves to a position away from the fixed clamping plate 5 and the movable clamping plate 8 is also moved away from the fixed clamping plate 5, the slider 7 also moves away from the fixed clamping plate 5 in the slide groove 6. This causes the spring 15 to be compressed by the slider 7 and the support plate 9. After the sliding mounting seat 2 is placed on the mixing tank 1, the movable clamping plate 8 is released. The pushing force of the spring 15 on the slider 7 can push the slider 7 towards the fixed clamping plate 5, thereby driving the movable clamping plate 8 towards the fixed clamping plate 5. Under the pushing force of the spring 15, the movable clamping plate 8 clamps the mixing tank 1 between the two sets of first anti-slip pads 13 fixed on the surfaces of the fixed clamping plate 5 and the movable clamping plate 8, thus achieving the pre-fixation of the sliding mounting seat 2. Then the sliding mounting seat 2 can be released to turn the screw 11. When turning the screw 11, it is not necessary to hold the sliding mounting seat 2 all the time, which saves more effort.

[0026] In actual use, according to the types and quantities of raw materials required for the synthesis of coating powder, a corresponding number of sliding mounting seats 2 are installed on the top of the mixing tank 1. The top of the sliding mounting seat 2 is equipped with a weight sensor 3 and a screw conveyor mechanism 4. First, the weight of the screw conveyor mechanism 4 in the idle state is measured by the weight sensor 3. Then, various raw materials are added to each group of screw conveyor mechanisms 4. After adding enough, the various raw materials are conveyed into the mixing tank 1 through the screw conveyor mechanism 4. Then, the mixing of each raw material is achieved by the rotation of the stirring shaft and stirring rod in the mixing tank 1.When installing the sliding mounting base 2 onto the mixing tank 1, first rotate the screw 11. Under the action of the threaded connection between the screw 11 and the screw hole 10, the push plate 12 moves away from the fixed clamping plate 5. Then, the movable clamping plate 8 is moved away from the fixed clamping plate 5, so that there is a sufficient gap between the movable clamping plate 8 and the fixed clamping plate 5. Then, place the sliding mounting base 2 on the mixing tank 1, so that the fixed clamping plate 5 is inside the mixing tank 1 and the movable clamping plate 8 is outside the mixing tank 1. Then, rotate the screw 11 in the opposite direction, so that the push plate 12 moves closer to the fixed clamping plate 5. Finally, the first anti-slip pad 13 fixed on the surface of the fixed clamping plate 5 abuts against the inner wall of the mixing tank 1. The push plate 12 pushes the movable clamping plate 8 to move the movable clamping plate 8. The first anti-slip pad 13 fixed on the surface of plate 8 is pressed against the outer wall of the mixing tank 1. The sliding mounting base 2 is installed on the mixing tank 1 through the friction between the two sets of first anti-slip pads 13 and the mixing tank 1. This device can adjust the distance between the fixed clamping plate 5 and the movable clamping plate 8 through the threaded connection of the screw hole 10 and the screw 11, overcoming possible errors during production. When the push plate 12 pushes the movable clamping plate 8, pressing the first anti-slip pad 13 fixed on the surface of the movable clamping plate 8 against the outer wall of the mixing tank 1, the second anti-slip pad 14 is also pressed between the movable clamping plate 8 and the push plate 12. The second anti-slip pad 14 is compressed when pressed. The second anti-slip pad 14 is made of a relatively rough and elastic rubber. Made of rubber, the second anti-slip pad 14 has a large frictional force with the movable clamping plate 8 when compressed, which increases the damping required for the second anti-slip pad 14 to rotate in the opposite direction, and thus increases the damping required for the push plate 12 and screw 11 to rotate in the loosening direction. At the same time, the second anti-slip pad 14 generates a pushing force on the push plate 12 under its own elasticity. This pushing force is transmitted to the screw 11, causing the threads between the screw hole 10 and the screw 11 to be compressed, thereby increasing the frictional force between the threads of the screw hole 10 and the screw 11. Under the dual action, the threads between the screw hole 10 and the screw 11 are prevented from loosening. When the push plate 12 moves to a position away from the fixed clamping plate 5, and the movable clamping plate 8 is also moved away from the fixed clamping plate 5, the sliding... Block 7 also moves away from the fixed clamping plate 5 in the slide groove 6, so that the spring 15 is compressed by the slider 7 and the support plate 9. After the sliding mounting seat 2 is placed on the mixing tank 1, the moving clamping plate 8 is released. The pushing force of the spring 15 on the slider 7 can push the slider 7 towards the fixed clamping plate 5, thereby driving the moving clamping plate 8 towards the fixed clamping plate 5. Under the pushing force of the spring 15, the moving clamping plate 8 clamps the mixing tank 1 between the two sets of first anti-slip pads 13 fixed on the surfaces of the fixed clamping plate 5 and the moving clamping plate 8, thus achieving the pre-fixation of the sliding mounting seat 2. Then the sliding mounting seat 2 can be released to turn the screw 11. When turning the screw 11, it is not necessary to hold the sliding mounting seat 2 all the time, which saves more effort.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
