AI Technical Summary
上述方案中由于采用固定式喷头的方式,导致清洗存在盲区、清洗液覆盖不均匀,无法根据辊面不同部位的污染情况灵活、精准地调整冲洗角度,从而造成清洗不彻底、效率低下的问题
1、当电动推杆的输出端连杆运动时,由于所有支杆均与该连杆枢接,而每根支杆又固定在一个套筒上,因此连杆的位移会同步地传递给每一个套筒,迫使它们围绕各自的连接头同步转动;由于喷头固定安装在套筒下端,套筒的转动直接转化为喷头喷射角度的改变;确保了所有喷头的偏转角度时刻保持一致,从而能根据清洗需要,将清洗液精准、均匀地喷射到三个辊筒的任意特定区域,如正上方用于冲刷,或侧前方用于切向刮洗。

Technical Field
[0001] This utility model relates to the technical field of three-roll mills, specifically to a cleaning device for three-roll mills. Background Technology
[0002] Three-roll mills are the most effective grinding and dispersing equipment for high-viscosity materials and are widely used in industries such as coatings, inks, pigments, and plastics. According to CN222343001U, a three-roll mill device with a cleaning structure is disclosed. This technology discloses "a three-roll mill device with a cleaning structure, which relates to the field of three-roll mill technology, including a three-roll mill body, a mounting frame, and a discharge plate. The mounting frame is installed on the top of the three-roll mill body, and a portion of the discharge plate is fixedly installed inside the three-roll mill body. The discharge plate is located on the front side of the three-roll mill body. A stirring-type mobile cleaning component is installed through the mounting frame and is located above the three-roll mill body. The stirring-type mobile cleaning component includes a liquid storage tank, the bottom of which is fixedly installed on the top of the mounting frame. A rotating motor is fixedly installed on one side of the liquid storage tank, and a cleaning-friendly discharge guide component is fixedly installed on the top of the discharge plate." This technology has the following technical effects: "It can not only mix and stir the cleaning liquid and deionized water, but also perform mobile cleaning and rinsing of the three-roll mill body. At the same time, the size of the guide port can be flexibly adjusted, and it is easy to clean and highly practical." The above solution uses a fixed nozzle, which results in blind spots in the cleaning process, uneven coverage of the cleaning fluid, and an inability to flexibly and accurately adjust the rinsing angle according to the contamination of different parts of the roller surface, thus causing incomplete cleaning and low efficiency. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention provides a cleaning equipment for a three-roll mill, which drives all nozzles to deflect synchronously and precisely adjusts the spray angle; the cleaning fluid is continuously delivered through a unique channel to ensure unobstructed spraying at any angle, achieving efficient and comprehensive cleaning.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for a three-roll mill, comprising a three-roll mill body, wherein a cleaning mechanism is provided on the three-roll mill body for cleaning the rollers, and the cleaning mechanism includes: The spraying assembly includes three shafts fixed at both the left and right ends of the top of the three-roll mill body. An infusion pipe is rotatably installed between the left and right shafts, and the three infusion pipes are respectively located directly above the three rollers. Several connectors are fixedly connected to the front end of the infusion pipes. A sleeve is rotatably installed on the outside of the connector. A nozzle is fixedly connected to the lower end of the sleeve. A support rod is fixed to the upper end of the sleeve. Several support rods are pivotally connected to each other through the same connecting rod. The liquid supply assembly is located on the body of the three-roll mill and provides cleaning fluid to the spray assembly.
[0005] Preferably, the spraying assembly further includes a mounting bracket fixed on the shaft frame, on which an electric push rod is pivotally connected, and the output end of the electric push rod is pivotally connected to the end of the connecting rod.
[0006] Preferably, the spray assembly further includes a plurality of water outlet holes arranged circumferentially on the connector head.
[0007] Preferably, the injection assembly further includes a connecting tube that is fixed between the ends of the three infusion tubes.
[0008] Preferably, the liquid supply assembly includes a water tank fixed inside the three-roll mill body, with a recovery tank fixed at the upper end of the water tank and located below the three rollers.
[0009] Preferably, the liquid supply assembly further includes a filter box fixed to the outer wall of the three-roll mill body and connected to the water tank, a filter plate is installed inside the filter plate, a water pump is installed on the outer wall of the three-roll mill body, an outlet pipe is connected between the inlet of the water pump and the filter box, and an inlet pipe is connected between the outlet of the water pump and the connecting pipe.
[0010] Beneficial effects This invention provides a cleaning device for a three-roll mill. Compared with the prior art, it has the following advantages: 1. When the output end of the electric push rod moves, since all the support rods are pivotally connected to the connecting rod, and each support rod is fixed on a sleeve, the displacement of the connecting rod will be synchronously transmitted to each sleeve, forcing them to rotate synchronously around their respective connectors. Since the nozzle is fixedly installed at the lower end of the sleeve, the rotation of the sleeve is directly converted into a change in the spray angle of the nozzle. This ensures that the deflection angle of all nozzles remains consistent at all times, so that the cleaning fluid can be accurately and evenly sprayed onto any specific area of the three rollers according to the cleaning needs, such as rinsing directly above or tangential scraping to the side front.
[0011] 2. When the cleaning fluid in the infusion tube flows into the connector, it enters the sleeve through the circumferentially arranged water outlet holes and is finally sprayed out from the nozzle; this ensures that the delivery channel of the cleaning fluid remains unobstructed no matter how the sleeve drives the nozzle to rotate around the connector to adjust the angle.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0015] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a cleaning device for a three-roll mill, including a three-roll mill body 1, a cleaning mechanism 2 provided on the three-roll mill body 1 for cleaning the rollers, the cleaning mechanism 2 including: The spray assembly 21 includes three shafts 211 fixed at both the left and right ends of the top of the three-roll mill body 1. An infusion pipe 212 is rotatably installed between the left and right shafts 211, and the three infusion pipes 212 are respectively located directly above the three rollers. Several connectors 213 are connected and fixed at the front end of the infusion pipes 212. A sleeve 215 is rotatably installed on the outside of the connectors 213. A nozzle 216 is connected and fixed at the lower end of the sleeve 215. A support rod 217 is fixed at the upper end of the sleeve 215. Several support rods 217 are pivotally connected to each other through the same connecting rod 218. The liquid supply assembly 22 is mounted on the three-roll mill body 1 and is used to supply cleaning fluid to the spray assembly 21.
[0016] In this embodiment, the three infusion pipes 212 are precisely positioned directly above the three rollers of the equipment, ensuring that the cleaning fluid can vertically cover the surface of each roller. When the output end connecting rod 218 of the electric push rod 2110 moves, since all the support rods 217 are pivotally connected to the connecting rod 218, and each support rod 217 is fixed on a sleeve 215, the displacement of the connecting rod 218 will be synchronously transmitted to each sleeve 215, forcing them to rotate synchronously around their respective connectors 213. Since the nozzle 216 is fixedly installed at the lower end of the sleeve 215, the rotation of the sleeve 215 is directly converted into a change in the spray angle of the nozzle 216. This ensures that the deflection angle of all nozzles 216 remains consistent at all times, so that the cleaning fluid can be accurately and evenly sprayed onto any specific area of the three rollers according to the cleaning needs, such as directly above for rinsing, or to the side front for tangential scraping.
[0017] Specifically, the injection assembly 21 also includes a mounting bracket 219 fixed on the shaft bracket 211, on which an electric push rod 2110 is pivotally connected, and the output end of the electric push rod 2110 is pivotally connected to the end of the connecting rod 218.
[0018] In this embodiment, the spray angle is automatically adjusted, which improves the convenience and intelligence of equipment operation. Operators can remotely complete all cleaning parameter settings and adjustments without having to get close to the equipment.
[0019] Specifically, the spray assembly 21 also includes several water outlet holes 214 arranged circumferentially on the connector 213.
[0020] In this embodiment, when the cleaning fluid in the infusion tube 212 flows into the connector 213, it enters the sleeve 215 through the circumferentially arranged water outlet 214 and is finally sprayed out from the nozzle 216; so that no matter how the sleeve 215 drives the nozzle 216 to rotate around the connector 213 to adjust the angle, the delivery channel of the cleaning fluid always remains unobstructed.
[0021] Specifically, the injection assembly 21 also includes a connecting pipe 2111 that connects the ends of the three infusion tubes 212.
[0022] In this embodiment, the connecting pipe 2111 is fixedly connected between the ends of the three infusion pipes 212, connecting the three independent infusion pipes 212 into a unified fluid distribution system.
[0023] Specifically, the liquid supply assembly 22 includes a water tank 221 fixed inside the three-roll mill body 1, and a recovery tank 222 is fixed at the upper end of the water tank 221 and located below the three rollers.
[0024] In this embodiment, during operation, the waste liquid and pollutants washed off the surface of the roller are directly collected into the recycling tank 222 located directly below under the action of gravity, and then flow back into the water tank 221.
[0025] Specifically, the liquid supply assembly 22 also includes a filter box 223 fixed to the outer wall of the three-roll mill body 1 and connected to the water tank 221. A filter plate 224 is installed inside the filter plate 224. A water pump 225 is installed on the outer wall of the three-roll mill body 1. An outlet pipe 226 is connected between the inlet of the water pump 225 and the filter box 223. An inlet pipe 227 is connected between the outlet of the water pump 225 and the connecting pipe 2111.
[0026] In this embodiment, the waste liquid collected in the water tank 221 is pumped into the filter box 223. After being intercepted by the filter plate 224, solid particulate pollutants are effectively removed. The purified cleaning liquid is temporarily stored on the clean side of the filter box 223. Then, the water pump 225 draws and pressurizes it through the liquid outlet pipe 226, and then delivers it to the connecting pipe 2111 through the liquid inlet pipe 227 to provide a clean liquid source for the spray assembly 21.
[0027] The working principle and usage process of this utility model are as follows: First, during operation, the waste liquid and pollutants washed off the surface of the roller are directly collected into the recovery tank 222 located directly below under the action of gravity, and then flow back into the water tank 221; the waste liquid collected in the water tank 221 is pumped into the filter box 223, and after the interception of the filter plate 224, the solid particulate pollutants are effectively removed. The purified cleaning liquid is temporarily stored on the clean side of the filter box 223, and then pumped and pressurized by the water pump 225 through the liquid outlet pipe 226, and then transported to the connecting pipe 2111 through the liquid inlet pipe 227 to provide a clean liquid source for the spray assembly 21; Meanwhile, when the output end connecting rod 218 of the electric push rod 2110 moves, since all the support rods 217 are pivotally connected to the connecting rod 218, and each support rod 217 is fixed on a sleeve 215, the displacement of the connecting rod 218 will be synchronously transmitted to each sleeve 215, forcing them to rotate synchronously around their respective connecting heads 213. Since the nozzle 216 is fixedly installed at the lower end of the sleeve 215, the rotation of the sleeve 215 is directly converted into a change in the spray angle of the nozzle 216. This ensures that the deflection angle of all nozzles 216 remains consistent at all times, so that the cleaning fluid can be accurately and evenly sprayed onto any specific area of the three rollers according to the cleaning needs, such as rinsing directly above or tangential scraping to the side front.
