Description

Technical Field

[0001] The utility model relates to the technical field of workpiece cleaning, in particular to a circulation cleaning device. Background Art

[0002] Photocuring technology is a photoprocessing process that uses ultraviolet light of a certain wavelength to polymerize liquid epoxy acrylic resin into a solid state at high speed. The photocuring reaction is essentially a polymerization and cross-linking reaction initiated by light.

[0003] The existing curing printing is carried out in a resin tank. When the cured molded part is taken out of the resin tank, a part of the resin will remain on its surface. Therefore, the resin on the surface of the molded part needs to be cleaned.

[0004] In the prior art, the cleaning machine mainly performs ultrasonic vibration cleaning on the cured molded parts. The ultrasonic generator installed on it emits ultrasonic waves into the cleaning agent, and the emitted ultrasonic waves drive the cleaning agent to vibrate, so that the cleaning agent cleans the resin on the surface of the cured molded parts. However, when the ultrasonic generator in the cleaning machine replaces the cleaning agent, a certain volume of cleaning agent is often used until there are many impurities, and then it is replaced manually as a whole, which is inefficient. Moreover, if the cleaning agent is not returned to the cleaning machine in time, it will affect the normal operation of the cleaning machine. Utility Model Content

[0038] Example

[0039] This embodiment provides a circulating cleaning device, such as Figures 1 to 3 As shown, it includes: a base frame 1, a cleaning structure 2, a pipeline structure and a power structure, wherein the cleaning structure 2 includes a cleaning tank 21, a filtering component 22 and a liquid storage component 23, the pipeline structure includes a first pipeline 31, a second pipeline 32, a third pipeline 33 and a fourth pipeline 34; the power structure includes a first power component 41.

[0040] Specifically, the cleaning tank 21, the filter assembly 22 and the liquid storage assembly 23 are all fixedly arranged on the base frame 1. The cleaning tank 21 has a cleaning cavity with an opening on one side, and a cleaning agent is placed in the cleaning cavity. A driving member 5 is installed on the outside of the cleaning tank 21. The driving member 5 is an ultrasonic transducer. When cleaning, the workpiece needs to be placed in the cleaning cavity containing the cleaning agent for cleaning. The ultrasonic transducer is started to drive the cleaning agent in the cleaning tank 21 to vibrate to clean the workpiece; the filter assembly 22 is arranged below the cleaning tank 21, and the two ends of the first pipe 31 are respectively connected to the cleaning tank 21 and the filter assembly 22 to connect the cleaning tank 21 and the filter assembly 22. A switch valve body is also arranged on the first pipe 31;

[0041] The liquid storage component 23 is arranged above the cleaning tank 21, the second pipe 32 is connected to the filter component 22, the third pipe 33 is connected to the liquid storage component 23, and both ends of the fourth pipe 34 are respectively connected to the liquid storage component 23 and the cleaning tank 21 so that the liquid storage component 23 and the cleaning tank 21 are connected; a switch valve body is arranged on the fourth pipe 34;

[0042] When the cleaning tank 21 cleans the workpiece, the switch valve body of the first pipe 31 is closed, the first pipe 31 is isolated, and a cleaning agent is placed in the cleaning chamber. The cleaning agent can be alcohol, and the workpiece is placed in the cleaning tank 21 to clean the workpiece. After the cleaning is completed, the switch valve body on the first pipe 31 is opened, and the cleaning agent with impurities in the cleaning tank 21 is introduced into the filter component 22 under the action of gravity; the filter component 22 filters the cleaning agent with impurities to remove the impurities. In this process, the switch valve body of the first pipe 31 can be closed again, and clean cleaning agent and workpieces can be placed in the cleaning tank 21 to carry out the next stage of cleaning operation.

[0043] When the filter assembly 22 has completed filtering the cleaning agent, the first opening and closing member 61 and the second opening and closing member 62 are opened, and the first power member 41 is started to introduce the cleaning agent that has been filtered in the filter assembly 22 into the liquid storage assembly 23 for storage; then, the first opening and closing member 61 and the second opening and closing member 62 are closed, and the switch valve body on the first pipe 31 is reopened to introduce the cleaning agent with impurities in the cleaning tank 21 in the second stage into the filter assembly 22 for filtration; when the next workpiece is to be cleaned, the switch valve body on the fourth pipe 34 is opened, and under the action of gravity, the cleaning agent in the liquid storage assembly 23 is quickly introduced into the cleaning tank 21 until an appropriate amount of cleaning agent is introduced, and the switch valve body on the fourth pipe 34 is closed. While the next stage of cleaning is being carried out, the first power member 41 introduces the cleaning agent in the filter assembly 22 into the liquid storage assembly 23.

[0044] Through the above-mentioned arrangement, by setting up the filtering component 22 and the liquid storage component 23, and connecting with the cleaning tank 21 by utilizing the pipeline structure and the power structure, the cleaning agent can be automatically discharged, filtered, stored and replaced in time, which saves labor and significantly improves the efficiency; and at the same time, the power structure is utilized to accelerate the flow speed of the cleaning agent, thereby improving the transportation efficiency of the cleaning agent and the cleaning efficiency of the entire device.

[0045] Specifically, Figure 1 and Figure 2As shown, the filter component 22 includes a first filter element 221 and a second filter element 222, and the first filter element 221 and the second filter element 222 are symmetrically arranged below the cleaning tank 21, and the first filter element 221 and the second filter element 222 are both connected to the cleaning tank 21 through the first pipe 31; the liquid storage component 23 includes a first liquid storage element 231 and a second liquid storage element 232, and the first liquid storage element 231 and the second liquid storage element 232 are both connected to the cleaning tank 21 through the fourth pipe 34, the first filter element 221 and the second filter element 222 are connected through the second pipe 32, and the first liquid storage element 231 and the second liquid storage element 232 are connected through the third pipe 33, and two first opening and closing members 61 are provided, and the two first opening and closing members 61 are relatively arranged on both sides of the connection point between the first power member 41 and the second pipe 32; two second opening and closing members 62 are provided, and the two second opening and closing members 62 are relatively arranged on both sides of the connection point between the first power member 41 and the third pipe 33.

[0046] When the circulating cleaning device cleans the workpiece, it needs to perform two cleanings. During the first cleaning (rough cleaning), the switch valve body on the first pipe 31 is closed, and the cleaning tank 21 performs the first rough cleaning on the workpiece. After the first cleaning is completed, the switch valve body on the first pipe 31 is opened to introduce the cleaning agent into the first filter element 221. After the filtration is completed, the first opening and closing member 61 close to the side of the first filter element 221 and the second opening and closing member 62 close to the side of the first liquid storage member 231 are opened, and the first power member 41 is started to introduce the filtered cleaning agent used for the first rough cleaning into the first liquid storage member 231 through the second pipe 32 and the third pipe 33. After the introduction is completed, the first opening and closing member 61 close to the side of the first filter element 221 and the second opening and closing member 62 close to the side of the first liquid storage member 231 are closed. Then the workpiece is cleaned for the second time. During the second cleaning (fine cleaning), the switch valve body on the first pipe 31 is closed, and the cleaning tank 21 performs a second fine cleaning on the workpiece. After the second cleaning is completed, the switch valve body on the first pipe 31 is opened to introduce the cleaning agent into the second filter element 222. After the filtering is completed, the first opening and closing member 61 close to the side of the second filter element 222 and the second opening and closing member 62 close to the side of the second liquid storage member 232 are opened, and the first power member 41 is started to introduce the filtered cleaning agent used for the second fine cleaning into the first liquid storage member 231 through the second pipe 32 and the third pipe 33. After the introduction is completed, the first opening and closing member 61 close to the side of the second filter element 222 and the second opening and closing member 62 close to the side of the second liquid storage member 232 are closed.

[0047] When the next workpiece is to be cleaned, during the first cleaning, the switch valve body on the fourth pipe 34 between the first liquid storage part 231 and the cleaning tank 21 is opened, and the switch valve body on the first pipe 31 is closed. Under the action of gravity, the cleaning agent stored in the first liquid storage part 231 is introduced into the cleaning tank to clean the workpiece, and the above-mentioned filtering process is repeated after the cleaning is completed; during the second cleaning, the switch valve body on the fourth pipe 34 between the second liquid storage part 232 and the cleaning tank 21 is opened, and the switch valve body on the first pipe 31 is closed. Under the action of gravity, the cleaning agent stored in the second liquid storage part 232 is introduced into the cleaning tank to clean the workpiece, and the above-mentioned filtering process is repeated after the cleaning is completed.

[0048] Through the above process, the cleaning agent is reused, saving cleaning costs. And by setting up two sets of liquid storage parts and filter parts, the cleaning agents used for rough washing and fine washing in the cleaning process are distinguished, avoiding repeated contamination caused by mixing the two sets of cleaning agents, resulting in subsequent rough washing or fine washing failures, and also avoiding long-term contact between workers and cleaning agents.

[0049] In this embodiment, if Figure 3 As shown, the power structure also includes a circulating power part 42, a fifth pipeline 35 and a sixth pipeline 36. The fifth pipeline 35 and the sixth pipeline 36 are respectively connected to the liquid outlet and the liquid inlet of the circulating power part 42, and the ends of the fifth pipeline 35 and the sixth pipeline 36 away from the circulating power part 42 are both connected to the cleaning chamber. In the process of the cleaning tank 21 cleaning the workpieces inside it, the circulating power part 42 works at the same time, extracts the cleaning agent from the liquid inlet end through the sixth pipeline 36, and sends the cleaning agent from the liquid outlet end of the circulating power part 42 through the fifth pipeline 35 back to the cleaning tank 21; drives the cleaning agent in the cleaning tank 21 to circulate through the fifth pipeline 35 and the sixth pipeline 36, accelerates the flow speed of the cleaning agent in the cleaning tank 21, and thus improves the cleaning efficiency of the cleaning agent on the workpiece surface.

[0050] In this embodiment, if Figure 1 and Figure 2 As shown, the first filter element 221 and the second filter element 222 each include a filter box 223 and a plurality of filter elements 224. A filter tank is provided in the filter box 223, and a plurality of filter elements 224 are arranged in the filter tank to filter and adhere impurities in the cleaning agent. The filter element 224 can be filter cotton, and before that, flocculants and other cleaning agents can be put into the filter tank to purify the cleaning agent.

[0051] In other practicable embodiments, the first pipe 31, the second pipe 32, the third pipe 33 and the fourth pipe 34 can be provided singly or in plurality. A plurality of first pipes 31 are provided side by side, a plurality of second pipes 32 are provided side by side, a plurality of third pipes 33 are provided side by side, and a plurality of fourth pipes 34 are provided side by side; the use of multiple circulation channels can further speed up the transmission rate of the cleaning agent. The first pipe 31, the second pipe 32, the third pipe 33 and the fourth pipe 34 are circular in cross section, and a smooth transition is used at the corner of the channel to increase the flow rate of the liquid in the pipe to a certain extent.

[0052] In other practicable manners, since cleaning agents are mostly flammable liquids, the first power member 41 and the circulating power member 42 are both configured as pneumatic pumps. The use of pneumatic pumps can avoid dangerous situations such as combustion of the cleaning agent to a certain extent.

[0053] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
