Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical product packaging technology, specifically a chemical product packaging device with automatic cleaning function. Background Technology
[0002] Chemical products refer to various substances produced through chemical processes. Their raw materials typically come from natural sources such as minerals, petroleum, natural gas, and biomass, and are transformed through a series of complex processing steps. These products include both basic chemical raw materials and highly processed fine chemicals, characterized by their wide variety and broad applications, and are an important foundation for modern industrial and social development.
[0003] The existing utility model patent with publication number CN221068552U discloses a quantitative packaging device for chemical products, including a base plate with multiple support rods fixedly connected to it. A top cylinder is fixedly connected to the support rods. A feeding assembly is provided on the top cylinder, which includes a bottom pipe, a sliding sleeve, a tank body, and a discharge pipe. The bottom pipe is fixedly connected to the bottom of the top cylinder, the sliding sleeve is slidably connected to the bottom pipe, the tank body is fixedly connected to the sliding sleeve, and the discharge pipe is fixedly connected to the bottom of the tank body. A counterweight assembly is connected to the feeding assembly. In this utility model, the chemical product in the top cylinder can be poured into the tank body. After the chemical product in the tank body is filled to a sufficient level, it will sink to facilitate packaging. By adjusting the position of the sliding seat, the amount of chemical product poured into the tank body each time can be controlled.
[0004] The aforementioned packaging device's discharge pipe is controlled to open and close only by a "plug." For viscous materials, residues are easily left on the inner walls of the tank and discharge pipe due to adhesion, resulting in the actual discharge volume being less than the tank's capacity each time. Furthermore, long-term accumulation of residual materials can contaminate subsequent materials. Additionally, for easily accumulated powdery or high-viscosity materials, the top cylinder lacks stirring, vibration, or heating devices, which can easily lead to feeding interruptions and affect continuous production.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A chemical product packaging device with automatic cleaning function includes a support frame, and a packaging mechanism is arranged above the support frame. Storage components, located above the support frame, are used to store materials; The drive assembly includes a drive tube disposed inside the storage assembly.

[0012] Beneficial effects This invention provides a chemical product packaging device with an automatic cleaning function. Compared with the prior art, it has the following advantages: (1) This chemical product packaging device with automatic cleaning function solves the problem of material residue through a combined "rinsing + scraping" method. During the cleaning stage, the water pump delivers water to the drive pipe through the connecting pipe and rotary joint. The nozzle at the end of the branch structure of the drive pipe sprays water onto the inner wall of the cylinder, forming a rinsing water flow. At the same time, the drive motor drives the drive pipe to rotate, and the scraper on its outer side rotates synchronously with the drive pipe. The outer edge of the scraper is in close contact with the inner wall of the cylinder, and the residual material attached to the inner wall is scraped off while the water flow is rinsing. When the arc plate at the bottom of the cylinder rotates with the drive pipe, it can also help clean the residual material on the inner wall of the conical structure. The combination of water flow and scraper can completely remove the residue at the inlet of the cylinder and the conveying pipe, avoiding long-term accumulation of material and contamination of subsequent materials.
[0013] (2) This chemical product packaging device with automatic cleaning function prevents material blockage through structural coordination. When the drive tube rotates, its bottom arc plate contacts the inner wall of the conical structure at the bottom of the cylinder, and the rotation drives the material to gather towards the center of the cylinder, avoiding the accumulation of material at the bottom edge of the cylinder; the lower end of the auger extends from the conical structure at the bottom of the cylinder to the bottom cylindrical pipe structure, and when it rotates continuously, it forms a stable pushing force on the material, continuously feeding the accumulated material into the conveying pipe, preventing blockage at the connection between the cylinder and the conveying pipe and inside the conveying pipe. At the same time, the inclined structure at the top of the inner wall of the conveying pipe guides the material to slide smoothly, and with the pushing action of the auger, ensures continuous material flow and avoids interruption of feeding due to accumulation of powdery or high-viscosity materials.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-4 This utility model provides a technical solution: a chemical product packaging device with automatic cleaning function, including a support frame 1, and a packaging mechanism 2 arranged above the support frame 1. Storage component 21, located above support frame 1, is used for storing materials. Storage component 21 includes a pressure sensor 211 fixedly installed at the bottom of support frame 1, a support plate 212 fixedly installed above pressure sensor 211, a material cylinder 213 fixedly installed at the center of support frame 1, a conveying pipe 214 fixedly installed at the bottom of material cylinder 213, a sealing ring 215 fixedly installed at the bottom of conveying pipe 214, a sealing ring 216 fitted into the inner wall of sealing ring 215, and a diaphragm 217 fixedly installed at the bottom of sealing ring 215. Pressure sensor 211 is symmetrically installed at the four corners of the bottom of support plate 212 with the center of support plate 212 as the reference. The bottom of material cylinder 213 has a conical structure, and a cylindrical pipe structure is provided at the bottom end of material cylinder 213. The top of the inner wall of conveying pipe 214 has a sloping structure. Sealing ring 215 is connected to conveying pipe 214 by threads. There are two diaphragms 217 with a relative angle of sixty degrees.
[0017] Specifically, the pressure sensor 211 can monitor the weight of the storage tank above the support plate 212, the material cylinder 213 can store materials, and the materials can enter the interior of the conveying pipe 214 under the guidance of the conical structure at the bottom of the material cylinder 213. The sealing ring 216 on the inner wall of the conveying pipe 214 can seal the gap between the conveying pipe 214 and the material cylinder 213. The outer side of the diaphragm 217 is a ring structure, and the inside is composed of an eight-lobed fan structure. The diaphragm 217 is made of silicone. Under no external force, the upper and lower diaphragms 217 stick together to block the flow.
[0018] The drive assembly 22 includes a drive pipe 221 disposed inside the storage assembly 21. A nozzle 222 is fixedly installed at the end of the branch structure of the drive pipe 221. A scraper 223 is fixedly installed on the outside of the drive pipe 221. An arc plate 224 and an auger 225 are fixedly installed at the bottom of the drive pipe 221. A gear 226 is inserted and installed at the top of the drive pipe 221. A rotary joint 227 is fixedly installed at the top of the drive pipe 221. The drive assembly 22 also includes a drive motor 228 fixedly installed on the top of the storage assembly 21. A gear 229 is fixedly installed on the outside of the shaft of the drive motor 228. A connecting pipe 2210 is fixedly installed at the top of the rotary joint 227. A water pump 2211 is fixedly installed at the bottom of 2210. A vertically equidistant "+" shaped branch structure is provided on the outside of the drive pipe 221. The drive pipe 221 and the material cylinder 213 are rotatably connected. There are three scrapers 223. The outer edge of the scraper 223 contacts the material cylinder 213. The lower end of the auger 225 extends downward from the bottom conical structure of the material cylinder 213 to the bottom cylindrical pipe structure of the material cylinder 213. The outer edge of the arc plate 224 contacts the inner wall of the bottom conical structure of the material cylinder 213. The gear 226 and the gear 229 mesh with each other. The drive motor 228 is fixed to the top of the material cylinder 213. The water pump 2211 is fixed to the outside of the plate-shaped structure on one side of the support frame 1.
[0019] Specifically, a water pump 2211 fixed to one side of the support frame 1 supplies water to the connecting pipe 2210 for rinsing the inner wall of the storage tank. After passing through the connecting pipe 2210, the rinsing water enters the drive pipe 221 through the rotary joint 227, and is then sprayed onto the inner wall of the storage tank by the nozzle 222. After starting, the drive motor 228 drives the drive pipe 221 to rotate through the gear 229 and the gear disc 226. The scraper 223, the arc plate 224, and the auger 225 fixed to the outside of the drive pipe 221 rotate. The scraper 223 cleans the inner wall of the storage tank during the cleaning process. During the conveying process, to prevent the material from sticking to the inner wall of the storage tank, the arc plate 224 can drive the material to gather towards the center of the storage tank, and the auger 225 can drive the material downward to the inside of the conveying pipe 214. As the auger 225 continues to rotate, it applies pressure to the material inside the conveying pipe 214. The diaphragm 217 at the bottom of the conveying pipe 214 will deform due to the increased pressure above, and the material can pass through the diaphragm 217 and enter the container. When the drive motor 228 stops, the diaphragm 217 will return to its original state and re-close the bottom of the conveying pipe 214 because the pressure above disappears.
[0020] Specifically, the pressure sensor 211 is model CBFS-200kg, the drive motor 228 is model YEJ, and the water pump 2211 is model QHX-250. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0021] During operation, materials are stored in the material cylinder 213, and containers to be filled are placed on top of the support plate 212. Pressure sensors 211 are symmetrically installed at the four corners of the bottom of the support plate 212 to monitor the weight of the containers. The drive motor 228 is started, and the gear 229 on the outside of its shaft meshes with the gear plate 226 on the top of the drive tube 221, driving the drive tube 221 to rotate inside the material cylinder 213. The outer edge of the scraper 223 on the outside of the drive tube 221 contacts the inner wall of the material cylinder 213, scraping off the material adhering to the inner wall as the drive tube 221 rotates; the outer edge of the arc plate 224 at the bottom contacts the inner wall of the conical structure at the bottom of the material cylinder 213, causing the material to gather towards the center; the lower end of the auger 225 extends into the cylindrical pipe structure at the bottom of the material cylinder 213, and when it rotates, it drives the material downward into the conveying pipe 214. Under the push of the auger 225, the material applies pressure to the diaphragm 217 at the bottom of the conveying pipe 214. The two diaphragms 217, which are at a 60-degree angle to each other, deform under pressure and open. The material passes through the gap sealed by the sealing ring 216 in the sealing ring 215 and enters the container through the diaphragm 217. After the pressure sensor 211 detects that the weight has reached the set value, it controls the drive motor 228 to stop, and the diaphragm 217 returns to its original position to seal the conveying pipe 214. During cleaning, the water pump 2211 supplies water to the drive pipe 221 through the connecting pipe 2210 and the rotary joint 227. The nozzle 222 at the end of the "+" shaped branch structure of the drive pipe 221 sprays water, and at the same time, the scraper 223 rotates continuously, working with the water flow to clean the residual material on the inner wall of the material cylinder 213.
