[0002] The plate heat exchanger mechanism of a coating machine is mainly a machine that performs heat exchange during the coating process. It can maintain the temperature of the workpiece during the coating process, thus maintaining the coating efficiency and quality. In use, it is assembled by precision metal plates. Different groups of plate heat exchangers are assembled according to the requirements to control the heat exchange effect. However, it is inconvenient to clean the inside of the plate heat exchanger during use, which can easily cause blockage and impurities in the internal cooling chamber.

This device includes a filter that is easy to assemble via the plate heat exchanger mechanism, effectively controlling the filter assembly to filter the water flow entering through the inlet pipe. Furthermore, after prolonged use, a drain valve assembled with a waste tank and drain pipe can effectively remove the waste filtered by the filter assembly, reducing the need for filter assembly replacement and minimizing economic waste. While the prior art can filter impurities, it is inconvenient to quickly clean impurities between the plate heat exchanger plates during operation, easily causing blockages and affecting heat exchange efficiency.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing plate-changing mechanism of the coating machine. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plate exchange mechanism for a coating machine with backwashing cleaning, comprising a plate exchange assembly and an inlet pipe and an outlet pipe mounted on the outer surface of the plate exchange assembly; including: a filter element, nested on the outer surface of the inlet pipe, with a filter plate slidably connected to the inner surface of the filter element, and a return spring elastically connected between the filter plate and the filter element; a pressing block rotatably connected to the inner surface of the filter element; a support frame mounted on the lower surface of the filter element; and a fixing plate connected to the support frame via a crank-connecting rod mechanism.

A waste liquid valve pipe is installed on the outer surface of the inlet pipe, and the waste liquid valve pipe is located between the inlet pipe and the plate heat exchanger assembly.

[0009] Preferably, the inlet pipe and valve body one form an integrated structure, and the inlet pipe and the outlet pipe form a water passage structure for cleaning through the transfer pipe, and the transfer pipe and valve body two form an integrated structure, while the outlet pipe and the outer surface end of valve body three are embedded and installed.

[0018] 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.

[0019] Please see Figures 1-6 The present invention provides the following technical solution: a plate heat exchange mechanism for a coating machine with backwash cleaning, comprising a plate heat exchange component 1 and an inlet pipe 2 and an outlet pipe 3 installed on the outer surface of the plate heat exchange component 1.

[0020] Example 1: As Figures 1-6 The present invention provides the following technical solution: a plate-changing mechanism for a coating machine with backwash cleaning, comprising: a filter element 4, nested on the outer surface of the water inlet pipe 2, and a filter plate 5 slidably connected to the inner surface of the filter element 4, and a return spring 6 elastically connected between the filter plate 5 and the filter element 4, while a pressing block 7 is rotatably connected to the inner surface of the filter element 4, and a support frame 8 is installed on the lower surface of the filter element 4, and the support frame 8 is connected to a fixing plate 13 through a crank-connecting rod mechanism.

[0021] During use, water is introduced through the inlet pipe 2 assembled in the heat exchanger assembly 1, and water is discharged through the outlet pipe 3 assembled in the heat exchanger assembly 1, thereby controlling the flow of cooling water. During operation, the filter plate 5 built into the filter element 4 assembled in the inlet pipe 2 is filtered. When impurities accumulate after prolonged filtration, the motor assembled on the side of the filter element 4 is activated to control the output shaft to rotate the squeezing block 7, thereby squeezing the filter plate 5. In conjunction with the reset spring 6 between the filter plate 5 and the filter element 4, the filter plate 5 is automatically reset after vibration and squeezing, improving the filtration effect while avoiding affecting normal operation.

[0022] Example 2: Figures 1-5 The technical solution shown, based on Embodiment 1, further discloses the stability of the backwash valve components, improving the cleaning effect and solving the problem of difficulty in synchronously controlling the cleaning. Its specific details are as follows: the inlet pipe 2 and the filter element 4 form an integrated structure, and the filter element 4 forms an elastic sliding structure with the filter plate 5 via a return spring 6. Furthermore, the filter element 4 and the extrusion block 7 form a rotating structure, and the filter plate 5 is extruded and connected to the outer surface of the extrusion block 7. Figure 3 , Figure 4 and Figure 5 As shown, the support frame 8 and the filter element 4 form a support structure. The filter element 4 is connected to a valve body 9 via an inlet pipe 2. A transfer pipe 16 is installed on the outer surface of the inlet pipe 2, located between the valve body 9 and the filter element 4. A valve body 10 is installed on the outer surface of the transfer pipe 16, and the other end of the transfer pipe 16 is installed on the outlet pipe 3. A valve body 11 is installed on the outer surface of the outlet pipe 3, located at the outlet end of the outlet pipe 3. A valve core 12 is telescopically connected to the inner surfaces of valve bodies 9, 10, and 11. A waste liquid valve pipe 17 is installed on the outer surface of the inlet pipe 2, located between the inlet pipe 2 and the plate heat exchanger assembly 1. Figure 4 and Figure 5As shown, the inlet pipe 2 and valve body 9 form an integrated structure, and the inlet pipe 2, through the transfer pipe 16, forms a water passage structure for cleaning with the outlet pipe 3. The transfer pipe 16 and valve body 10 form an integrated structure, while the outlet pipe 3 and valve body 11 are embedded at their outer surface ends. Figure 4 and Figure 5 As shown, valve body 19, valve body 20 and valve body 31 all form a sliding structure with valve core 12. Valve body 19 and valve body 311 are normally open structures, and valve body 210 is an open structure during cleaning. At the same time, waste liquid valve pipe 17 and water inlet pipe 2 form an integrated structure.

[0023] During backwashing, the valve core 12 inside the valve body 9 assembled through the inlet pipe 2 is moved down to close the water inlet of the inlet pipe 2, and the valve body 10 connected to the transfer pipe 16 assembled through the inlet pipe 2 is opened, so that the filtered water from the inlet pipe 2 is transported to the outlet pipe 3 through the transfer pipe 16. At the same time, the valve core 12 inside the valve body 11 assembled through the outlet pipe 3 is closed, so that the outlet pipe 3 is the inlet pipe for backwashing, and the waste liquid valve pipe 17 assembled through the inlet pipe 2 is the outlet. This controls the wastewater discharge effect and enables effective backwashing of the plate heat exchanger assembly 1.

[0024] Example 3: Figure 6 The technical solution shown, based on Embodiment 2, further discloses that the valve core 12 operates synchronously through a crank linkage mechanism, improving the stability of synchronous operation, preventing individual valves from jamming, and avoiding difficulties in backwashing. This solves the problem of valve jamming and difficulty in backwashing. The specific details are as follows: The crank linkage mechanism also includes a turntable 15 rotatably connected to the lower surface of the support frame 8, and the turntable 15 is connected to a moving rod 14 via an off-axis. A fixed plate 13 is rotatably connected to the inner surface of the moving rod 14, limiting and sliding the fixed plate 13 on the inner surface of the support frame 8. Simultaneously, the valve core 12 is installed on the upper surface of the fixed plate 13. Figure 6 As shown, the support frame 8 and the turntable 15 form a rotating structure, and the turntable 15 forms a circumferential linear movement structure with the fixed plate 13 through the moving rod 14. The fixed plate 13 and the support frame 8 form a sliding structure, and the fixed plate 13 is embedded in the lower surface of the valve core 12.

[0025] When backwashing is required, the motor of the support frame 8 is started to rotate, thereby controlling the turntable 15 to rotate. This drives the moving rod 14 to adjust the fixed plate 13 to move up and down on the inner surface of the support frame 8, thereby improving the stability of the fixed plate 13 in driving the multiple valve cores 12 and preventing tilting or jamming, thus improving the stability of the operation.

[0026] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[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.
