Description

Technical Field

[0001] This utility model relates to the field of release agent production technology, and in particular to a release agent raw material proportioning device. Background Technology

[0002] Release agent is a chemical substance used to prevent materials (such as plastics, rubber, composite materials, etc.) from sticking to the mold surface during the molding process. It forms a release film on the mold surface, allowing the product to be easily demolded after curing or cooling, while maintaining the integrity of the product surface and the mold. Release agent raw material proportioning equipment is a special equipment used to mix and proportion various raw materials required for release agent production in precise proportions.

[0003] Traditional release agent raw material proportioning equipment cannot automatically screen raw materials during the feeding stage, resulting in raw materials entering the equipment often containing impurities. These impurities not only affect the quality stability of the release agent but may also cause wear and tear on subsequent production equipment, shortening its service life. At the same time, the equipment cleaning work is cumbersome. Manual cleaning not only consumes a lot of manpower and time but also makes it difficult to ensure the thoroughness of cleaning. Residual raw materials are prone to accumulate and deteriorate inside the equipment, causing cross-contamination and seriously affecting the quality of the release agent product. Therefore, we have proposed a release agent raw material proportioning equipment to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing release agent raw material proportioning equipment, which cannot automatically screen raw materials during feeding, leading to impurities being mixed in and affecting product quality. In addition, the equipment is cumbersome to clean, and manual cleaning is labor-intensive, time-consuming, and incomplete, easily causing cross-contamination. Therefore, this invention proposes a release agent raw material proportioning equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A release agent raw material proportioning device includes a support frame, a mixing tank fixedly connected to the top of the support frame, a sealing cover fixedly connected to the top of the mixing tank, a liquid inlet fixedly connected to the top of the sealing cover, the liquid inlet communicating with the interior of the mixing tank, a stirring shaft rotatably mounted on the sealing cover, the stirring shaft extending into the interior of the mixing tank and fixedly connected to a stirring frame, both sides of the stirring frame contacting the inner wall of the mixing tank, a driving assembly for driving the stirring shaft to rotate being provided on the top of the sealing cover, a feed inlet communicating with the interior of the mixing tank being opened on the top of the sealing cover, a screening box fixedly connected to the top of the sealing cover at the feed inlet, a feeding mechanism being connected to the top of the screening box, and further includes;

[0007] A screening component, which is installed on a screening box, is used to screen materials entering the mixing tank;

[0008] A cleaning assembly, located on the mixing tank, is used to clean the interior of the mixing tank.

[0009] The fixed frame is fixedly installed on the top of the support frame. A feeding pipe is fixedly connected inside the fixed frame. A feeding bin is fixedly connected to the top of the fixed frame. The feeding bin is connected to the inlet of the feeding pipe. The outlet of the feeding pipe is connected to the top of the screening box. A spiral feeding rod is rotatably installed inside the feeding pipe. A second gear reducer is fixedly connected to one end of the feeding pipe. The output end of the second gear reducer is fixedly connected to the spiral feeding rod. A second motor is fixedly connected to one side of the second gear reducer. The output end of the second motor is fixedly connected to the input end of the second gear reducer.

[0010] In one possible design, the cleaning assembly includes two cleaning pipes, both of which are rotatably mounted through a sealing cover. Both cleaning pipes extend into the interior of the mixing tank and are fixedly connected to a cleaning frame. The bottom of each of the two cleaning frames is fixedly connected to multiple water spray heads. The top of the two cleaning pipes is rotatably connected to a common connecting pipe, which is connected to an external high-pressure water source.

[0011] The drive assembly includes a first gear reducer, which is fixedly mounted on the top of the sealing cover. The output end of the first gear reducer is fixedly connected to the stirring shaft. A first motor is fixedly connected to the top of the first gear reducer, and the output end of the first motor is fixedly connected to the input end of the first gear reducer. A drive gear is fixedly connected to the stirring shaft inside the stirring tank. Driven gears are fixedly fitted on both of the two cleaning pipes, and both driven gears are meshed with the drive gear.

[0012] In one possible design, the screening assembly includes two slide rods, which are respectively fixedly installed on the inner walls of the screening box on opposite sides. The two slide rods are slidably connected to the same screening frame, and a screen is fixedly installed inside the screening frame. An opening is provided on one side of the screening box.

[0013] In one possible design, a connecting rod is fixedly connected to one side of the screening rack. The connecting rod slides through one side of the screening box. A slot is opened on the top of the connecting rod on the outside of the screening box. A connecting block is fitted into the slot. Two limiting wheels are symmetrically connected to the top of the connecting block via a rotating shaft. Two fixing bolts are threaded onto the connecting rod. The two fixing bolts extend into the slot and are threadedly connected to the connecting block. One end of the spiral feeding rod extends to the outside of the feeding pipe and is fixedly fitted with a cam. The cam is inclined and located between the two limiting wheels.

[0014] In this application, firstly, when the equipment is started, the second motor is turned on. The second motor outputs power, which is reduced in speed and increased in torque through the second gear reducer, driving the screw feeder to rotate inside the feed pipe. The raw material in the feed bin is pushed by the screw feeder and transported to the screening box along the feed pipe. During the rotation of the screw feeder, the cam at one end rotates accordingly. The cam moves between two limit wheels. As the inclined cam rotates, it will continuously squeeze the limit wheels, thereby driving the connecting block, connecting rod and screening frame to slide back and forth on the slide bar. When the raw material falls into the screen of the screening frame, it is screened under the reciprocating motion of the screen. The raw material that meets the particle size requirements passes through the screen and enters the mixing tank, while impurities remain on the screen surface and can be cleaned through the opening on one side of the screening box.

[0015] At the same time, the first motor is started, and the first motor outputs power. After the first gear reducer reduces the speed and increases the torque, it drives the stirring shaft to rotate. The stirring shaft drives the stirring frame to rotate inside the mixing tank, stirring and mixing the raw materials entering the mixing tank and the original liquid entering through the liquid inlet. At the same time, the stirring frame, which is in contact with the inner wall of the mixing tank, can scrape off the raw materials adhering to the inner wall of the mixing tank, improving the mixing effect.

[0016] When the mixing tank needs to be cleaned after the raw materials are discharged, the first motor continues to start, driving the mixing shaft to rotate. The drive gear on it rotates accordingly. The drive gear meshes with the driven gears on the two cleaning pipes, driving the cleaning pipes and the cleaning frame fixed at its bottom to rotate. An external high-pressure water source supplies water to the spray head at the bottom of the cleaning frame through the connecting pipe and the cleaning pipe. The rotating spray head sprays out high-pressure water, which, together with the mixing frame in contact with the inner wall of the mixing tank, cleans the inner wall of the mixing tank and the mixing frame.

[0017] Beneficial effects: In this utility model, the release agent raw material proportioning device sets a screening component on the screening box and uses a cam to drive the screening frame to reciprocate to screen the raw materials entering the equipment. This can effectively remove impurities from the raw materials and ensure that only raw materials that meet the particle size requirements enter the mixing tank for proportioning. This greatly improves the quality stability of the release agent product and reduces product quality problems caused by impurities.

[0018] In this utility model, the release agent raw material proportioning equipment, through the feeding mechanism and driven by the second motor and the second gear reducer, can stably and efficiently transport the raw materials from the feeding bin to the screening box, providing a continuous and stable supply of raw materials for screening and subsequent proportioning processes, thereby improving the overall production efficiency;

[0019] In this invention, the release agent raw material proportioning equipment utilizes a cleaning pipe and a cleaning frame connected to the stirring shaft via a cleaning component. When the stirring shaft rotates, it drives the cleaning frame to rotate, spraying high-pressure water from the spray head to thoroughly clean the inside of the mixing tank. This reduces the workload of manual cleaning, improves cleaning efficiency, and reduces the risk of cross-contamination.

[0020] In this invention, by setting a screening component, impurities in raw materials can be efficiently removed, improving the quality stability of release agent products and reducing quality problems caused by impurities. The feeding mechanism can stably and efficiently transport raw materials from the feeding hopper to the screening box, providing a continuous and stable supply of raw materials for subsequent screening and proportioning processes. The cleaning component uses the rotation of the stirring shaft to drive the cleaning frame to rotate, spraying high-pressure water jets to thoroughly clean the mixing tank, greatly reducing the amount of manual cleaning work.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] The support frame 1 serves as the support structure for the entire equipment, with a mixing tank 2 fixedly connected to its top. The mixing tank 2 is used to hold and mix the release agent raw materials. A sealing cover 3 is fixedly connected to the top of the mixing tank 2, and a liquid inlet 8 is fixedly connected to the top of the sealing cover 3. The liquid inlet 8 is connected to the interior of the mixing tank 2 for adding liquid raw materials into the mixing tank 2. A stirring shaft 6 is rotatably mounted on the sealing cover 3. The stirring shaft 6 extends into the interior of the mixing tank and is fixedly connected to a stirring frame 7. Both sides of the stirring frame 7 are in contact with the inner wall of the mixing tank for thoroughly mixing the raw materials in the mixing tank 2. A drive assembly for driving the stirring shaft 6 is located on the top of the sealing cover 3. The drive assembly includes a first gear reducer 4 and a first motor 5. The first gear reducer 4 is fixedly mounted on the top of the sealing cover 3, and its output end is fixedly connected to the stirring shaft 6. The first motor 5 is fixedly connected to the top of the first gear reducer 4, and its output end is fixedly connected to the input end of the first gear reducer 4. The rotation of the first motor 5, after being reduced in speed by the first gear reducer 4, drives the stirring shaft 6 and the stirring frame 7 to rotate, thereby achieving the stirring and mixing of the raw materials in the stirring tank 2.

[0031] The top of the sealing cover 3 has an inlet that communicates with the interior of the mixing tank. A screening box 15 is fixedly connected to the top of the sealing cover 3 at the inlet, and a feeding mechanism is connected to the top of the screening box 15. The feeding mechanism includes a fixed frame 9, a feeding pipe 10, a feeding bin 11, a spiral feeding rod 12, a second gear reducer 13, and a second motor 14. The fixed frame 9 is fixedly mounted on the top of the support frame 1. The feeding pipe 10 is fixedly connected inside the fixed frame 9, and the feeding bin 11 is fixedly connected to the top of the fixed frame 9. The feeding bin 11 is connected to the inlet of the feeding pipe 10, and the outlet of the feeding pipe 10 is connected to the top of the screening box 15. The feeding pipe 10 has a rotating spiral feeding rod 12 inside. One end of the feeding pipe 10 is fixedly connected to a second gear reducer 13. The output end of the second gear reducer 13 is fixedly connected to the spiral feeding rod 12. A second motor 14 is fixedly connected to one side of the second gear reducer 13. The output end of the second motor 14 is fixedly connected to the input end of the second gear reducer 13.

[0032] In practical applications, solid raw materials are placed into the feeding bin 11, the second motor 14 is started, and after being reduced in speed by the second gear reducer 13, it drives the screw feeder 12 to rotate, conveying the solid raw materials in the feeding bin 11 to the screening box 15. The design of the feeding mechanism realizes the automatic conveying of solid raw materials, improves production efficiency, reduces manual operation, and reduces labor intensity.

[0033] A screening assembly is installed on the screening box 15 for screening materials entering the mixing tank. The screening assembly includes two slide rods 16, a screening frame 17, a connecting rod 18, a connecting block 19, fixing bolts 20, limiting wheels 21, and a cam 22. The two slide rods 16 are respectively fixedly installed on the inner walls of the two opposite sides of the screening box 15. The same screening frame 17 is slidably connected between the two slide rods 16. A screen is fixedly installed inside the screening frame 17. An opening is provided on one side of the screening box 15. A connecting rod 18 is fixedly connected to one side of the screening frame 17. The connecting rod 18 slides through one side of the screening box 15. A slot is opened on the top of the connecting rod 18 on the outside of the screening box 15. A connecting block 19 is fitted into the slot. Two limiting wheels 21 are symmetrically connected to the top of the connecting block 19 via a rotating shaft. Two fixing bolts 20 are threadedly connected to the connecting rod 18. The two fixing bolts 20 extend into the slot and are threadedly connected to the connecting block 19. One end of the spiral feed rod 12 extends to the outside of the feed tube 10 and is fixedly fitted with a cam 22, which is inclined and located between two limit wheels 21.

[0034] When the screw feed rod 12 rotates, it drives the cam 22 to rotate. The rotation of the cam 22 pushes the limit wheel 21 and the connecting block 19 to move, which in turn drives the connecting rod 18 and the screening frame 17 to slide back and forth on the slide rod 16, thereby screening solid raw materials. The design of the screening assembly can effectively remove impurities and large particles from solid raw materials, ensuring the quality of the release agent raw materials. At the same time, the snap-fit ​​connection between the connecting block 19 and the connecting rod 18 and the fixing bolt 20 facilitate the disassembly and cleaning of the screening frame 17.

[0035] This application can be used in the field of release agent production technology, or in other fields applicable to this application.

A driving gear 27 is fixedly connected to the stirring shaft 6 inside the mixing tank 2. Driven gears 26 are fixedly fitted onto each of the two cleaning pipes 23, and both driven gears 26 mesh with the driving gear 27.

[0037] After mixing, when cleaning the inside of mixing tank 2 is required, the connecting pipe 25 is connected to an external high-pressure water source, and the first motor 5 is started, driving the mixing shaft 6 and the drive gear 27 to rotate. The rotation of the drive gear 27 drives the driven gear 26 and the cleaning pipe 23 to rotate, which in turn drives the cleaning frame 24 to rotate. At the same time, high-pressure water enters the cleaning pipe 23 and the cleaning frame 24 through the connecting pipe 25 and is sprayed out from the spray nozzle to thoroughly clean the inside of mixing tank 2. The design of the cleaning components can effectively remove residual raw materials inside mixing tank 2, ensuring the cleanliness and hygiene of the equipment and extending its service life.
