[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1: The present invention utilizes the liquid property of the PE plastic particles in the melted state, so that the PE plastic particles in the melted state can be completely attached to the upper surface of the heat transfer corrugated plate that needs to be polished. When the PE plastic particles in the melted state are completely attached to the upper surface of the heat transfer corrugated plate, the electric heating rod and the second motor are turned off, and the PE plastic particles in the melted state can be cooled and solidified. The solidified PE plastic particles can be completely attached to the upper surface of the heat transfer corrugated plate, and the fluororubber strips on the top of the fluororubber film are inserted into the PE plastic particles in the melted state.

[0019] 2: In the present invention, the solidified PE plastic particles and the fluororubber film are completely attached to the upper surface of the heat transfer corrugated plate. When the solidified PE plastic particles drive the fluororubber film to make a reciprocating motion, the frosting on the bottom of the fluororubber film can be used to fully polish the upper surface of the heat transfer corrugated plate, and the gaps on the heat transfer corrugated plate can also be polished.

[0020] 3: In the present invention, melted PE plastic particles are used to drive the fluororubber film to adhere to the upper surface of the heat transfer corrugated plate. The device can be used to adhere heat transfer corrugated plates of different sizes, so that the solidified PE plastic particles are solidified into corresponding sizes according to the heat transfer corrugated plates of different sizes. The device can polish the heat transfer corrugated plates of different sizes. It is only necessary to melt the PE plastic particles, adhere the heat transfer corrugated plates of different sizes, and then solidify the PE plastic particles to obtain the size of the heat transfer corrugated plates of corresponding sizes, and then polish the heat transfer corrugated plates of different sizes.

[0021] 4: In the present invention, the friction between the fluororubber membrane and the heat transfer corrugated plate is greater than the friction between the heat transfer corrugated plate and the loading platform. When the shell drives the fluororubber membrane to move laterally, the fluororubber membrane drives the heat transfer corrugated plate to move laterally on the loading platform until the heat transfer corrugated plate moves laterally into the limiting groove and stops, thereby automatically completing the loading process of the heat transfer corrugated plate.

[0022] 5: In the present invention, the shell, the solidified PE plastic particles in the shell and the fluororubber film generate a downward squeezing force on the polished heat transfer corrugated plate, and the friction between the fluororubber film and the heat transfer corrugated plate is greater than the friction between the heat transfer corrugated plate and the bearing plate.

[0042] As a technical optimization solution of the present invention, the limiting mechanism includes a workbench 32 installed on the base plate 1, the workbench 32 is located below the fluororubber membrane 26, a limiting groove 34 is provided on the top of the workbench 32, a second electric telescopic rod 35 is installed on the bottom wall of the limiting groove 34, the piston rod end of the second electric telescopic rod 35 is connected to a bearing plate 33, the bearing plate 33 is installed in the limiting groove 34 for sliding up and down, and the workbench 32 is located between the two pedestals 14.

[0043] As a technical optimization scheme of the present invention, a first support plate 17 is installed on the base plate 1, a unloading platform 18 is installed on the top of the first support plate 17, a second support plate 19 is installed on the base plate 1, a loading platform 20 is installed on the top of the second support plate 19, a workbench 32 is located between the unloading platform 18 and the loading platform 20, the tops of the workbench 32, the unloading platform 18 and the loading platform 20 are flush, two guide bars 21 are installed on the tops of the workbench 32, the unloading platform 18 and the loading platform 20, the heat transfer corrugated plate 16 is placed on the loading platform 20, the heat transfer corrugated plate 16 is located between the two guide bars 21, the top of the heat transfer corrugated plate 16 is located above the guide bars 21, and the guide bars 21 can provide limiting and guiding for the heat transfer corrugated plate 16 moving on the loading platform 20 and the unloading platform 18.

[0044] As a technical optimization solution of the present invention, a guide rail 2 is installed on the base plate 1, an electric slider 3 is slidably installed on the guide rail 2, a first electric telescopic rod 4 is installed on the top of the electric slider 3, and a reinforcement block 22 is installed at the end of the piston rod of the first electric telescopic rod 4, and the reinforcement block 22 is fixed to the bottom of the mounting plate 5.

[0045] When the present invention is in use, when the heat transfer corrugated plate 16 needs to be polished, first, the heat transfer corrugated plate 16 that needs to be polished is transported to the loading platform 20 through an external transport device.

[0046] After the heat transfer corrugated plate 16 that needs to be polished is transferred to the loading platform 20, the electric slider 3 is started, and the electric slider 3 slides horizontally on the guide rail 2, thereby driving the two first electric telescopic rods 4 and the two mounting plates 5 to slide horizontally, and then driving the shell 13 to move horizontally until the shell 13 moves horizontally to the top of the heat transfer corrugated plate 16 on the loading platform 20 and stops. At this time, the two first electric telescopic rods 4 are started at the same time, and the piston rods of the two first electric telescopic rods 4 retract to drive the two mounting plates 5 to move downward at the same time. The downward movement of the two mounting plates 5 can drive the shell 13 to move downward, and the downward movement of the shell 13 can drive the fluororubber membrane 26 at the bottom of the shell 13 to move downward until the fluororubber membrane 26 moves downward to produce a downward squeezing force on the heat transfer corrugated plate 16 on the loading platform 20 and then stops, and the friction between the fluororubber membrane 26 and the heat transfer corrugated plate 16 is greater than the friction between the heat transfer corrugated plate 16 and the loading platform 20.

[0047] When the fluororubber membrane 26 generates a downward squeezing force on the heat transfer corrugated plate 16 on the loading platform 20, the electric slider 3 is started again, and the electric slider 3 moves laterally on the guide rail 2, thereby causing the two mounting plates 5 and the shell 13 to move laterally. The lateral movement of the shell 13 drives the fluororubber membrane 26 to move laterally. By utilizing the friction force between the fluororubber membrane 26 and the heat transfer corrugated plate 16 being greater than the friction force between the heat transfer corrugated plate 16 and the loading platform 20, when the shell 13 drives the fluororubber membrane 26 to move laterally, the fluororubber membrane 26 drives the heat transfer corrugated plate 16 to move laterally on the loading platform 20 until the heat transfer corrugated plate 16 moves laterally into the limiting groove 34 and stops, thereby automatically completing the loading process of the heat transfer corrugated plate 16.

[0048] When the heat transfer corrugated plate 16 moves laterally into the limiting groove 34, the limiting groove 34 is used to limit the heat transfer corrugated plate 16, and the heat transfer corrugated plate 16 can be limited and fixed in the limiting groove 34. The bearing plate 33 is used to provide a bearing effect on the heat transfer corrugated plate 16, and then the heat transfer corrugated plate 16 is limited and fixed in the limiting groove 34.

[0049] After the heat transfer corrugated plate 16 to be polished is limited and fixed in the limiting groove 34, the two first electric telescopic rods 4 are started to move the two mounting plates 5 downward, and the mounting plates 5 move downward to drive the shell 13 to move downward, and the shell 13 moves downward to drive the fluororubber membrane 26 to move downward to generate an extrusion force on the heat transfer corrugated plate 16 in the limiting groove 34, and the PE plastic particles 36 in the shell 13 and the fluororubber membrane 26 generate an extrusion force on the heat transfer corrugated plate 16 in the limiting groove 34, so that the bent and deformed heat transfer corrugated plate 16 can be squeezed and straightened, and the bent and deformed heat transfer corrugated plate 16 can be pressed and flattened to avoid the bending and deformation of the heat transfer corrugated plate 16 itself affecting the polishing effect of the heat transfer corrugated plate 16 in the later stage, and the fluororubber membrane 26 provides a flexible extrusion force for the heat transfer corrugated plate 16 to avoid the heat transfer corrugated plate 16 being damaged by rigid extrusion, thereby improving the protection of the heat transfer corrugated plate 16.

[0050] After the heat transfer corrugated plate 16 is extruded and flattened, the electric heating rod 30 is started. The electric heating rod 30 heats the PE plastic particles 36 in the shell 13. The PE plastic particles 36 melt after being heated. The melting point of the fluororubber film 26 is higher than that of the PE plastic particles 36. When the PE plastic particles 36 melt, the fluororubber film 26 will not melt. The PE plastic particles 36 are heated by the electric heating rod 30 to melt the PE plastic particles 36. The second motor 23 is started. The output shaft of the second motor 23 can mobilize the first gear 24 to rotate. The rotation of the first gear 24 can make the two second gears 25 rotate in the opposite direction. The reverse rotation of the two second gears 25 can mobilize the two connecting shafts 29 to rotate in the opposite direction. The reverse rotation of the two connecting shafts 29 can make the electric heating rods 30 installed on the outer walls of the two connecting shafts 29 rotate in the opposite direction to stir the PE plastic particles 36 in the shell 13 in the melted state, thereby uniformly heating the PE plastic particles 36 in the shell 13, so that the PE plastic particles 36 in the shell 13 are completely melted.

[0051] After the PE plastic particles 36 in the shell 13 are heated and melted by the electric heating rod 30, the two first electric telescopic rods 4 are started again, and the piston rods of the first electric telescopic rods 4 are retracted to move the mounting plate 5 downward, thereby moving the shell 13 downward until the bottom of the fluororubber film 26 at the bottom of the shell 13 contacts the heat transfer corrugated plate 16, and the melted PE plastic particles 36 provide a pressure to the fluororubber film 26, so that the melted PE plastic particles 36 can be attached to the upper surface of the heat transfer corrugated plate 16 through the fluororubber film 26. The melted PE plastic particles 36 can be attached to the upper surface of the heat transfer corrugated plate 16 to allow the melted PE plastic particles 36 to enter the gaps of the heat transfer corrugated plate 16, and the liquid properties of the melted PE plastic particles 36 can be used to , the PE plastic particles 36 in the melted state can be completely attached to the upper surface of the heat transfer corrugated plate 16 that needs to be polished. When the PE plastic particles 36 in the melted state are completely attached to the upper surface of the heat transfer corrugated plate 16, the electric heating rod 30 and the second motor 23 are turned off, and the PE plastic particles 36 in the melted state can be cooled and solidified. The solidified PE plastic particles 36 can be completely attached to the upper surface of the heat transfer corrugated plate 16, and the fluororubber strip 31 on the top of the fluororubber film 26 is inserted into the PE plastic particles 36 in the melted state. When the PE plastic particles 36 in the melted state are solidified, the shape of the fluororubber film 26 also changes with the shape of the solidified PE plastic particles 36, so that the fluororubber film 26 can be completely attached to the upper surface of the heat transfer corrugated plate 16.

[0052] When the solidified PE plastic particles 36 and the fluororubber film 26 are completely attached to the upper surface of the heat transfer corrugated plate 16, the first motor 6 is started, and the output shaft of the first motor 6 can mobilize the reciprocating screw 7 to rotate, so that the internal thread block 8 can reciprocate on the reciprocating screw 7, thereby driving the shell 13, the fluororubber film 26 and the solidified PE plastic particles 36 in the shell 13 to reciprocate, and then the solidified PE plastic particles 36 drive the fluororubber film 26 to reciprocate to polish the upper surface of the heat transfer corrugated plate 16, which uses the solidified PE plastic particles 36 and the fluororubber film 26 to completely attach to the upper surface of the heat transfer corrugated plate 16. When the PE plastic particles 36 drive the fluororubber film 26 to make a reciprocating motion, the frosting 27 at the bottom of the fluororubber film 26 can be used to perform a comprehensive polishing process on the upper surface of the heat transfer corrugated plate 16, and the gaps on the heat transfer corrugated plate 16 can also be polished. The upper surface of the heat transfer corrugated plate 16 and the gaps on the upper surface of the heat transfer corrugated plate 16 can be polished at one time, thereby improving the comprehensiveness of the polishing of the heat transfer corrugated plate 16. There is no need to polish the gaps of the heat transfer corrugated plate 16 separately at a later stage. The upper surface of the heat transfer corrugated plate 16 can be fully polished at one time by using the device, and the upper surface of the heat transfer corrugated plate 16 can be fully and thoroughly polished.

[0053] The molten PE plastic particles 36 are used to drive the fluororubber film 26 to adhere to the upper surface of the heat transfer corrugated plate 16. The device can be used to adhere heat transfer corrugated plates 16 of different sizes, so that the solidified PE plastic particles 36 are solidified into corresponding sizes according to the heat transfer corrugated plates 16 of different sizes. The device can polish the heat transfer corrugated plates 16 of different sizes. It is only necessary to melt the PE plastic particles 36, adhere the heat transfer corrugated plates 16 of different sizes, and then solidify the PE plastic particles 36 to obtain the size of the heat transfer corrugated plates 16 of the corresponding size, and then polish the heat transfer corrugated plates 16 of different sizes.

[0054] When the solidified PE plastic particles 36 drive the fluororubber film 26 to perform reciprocating motion and the heat transfer corrugated plate 16 is polished by the frosting 27, the shell 13 drives the PE plastic particles 36 and the fluororubber film 26 to perform horizontal motion. After the fluororubber film 26 moves to contact the water-absorbing sponge block 15, as the shell 13 continues to move, when the shell 13 moves above the water-absorbing sponge block 15, the fluororubber film 26 can be squeezed with the water-absorbing sponge block 15, and the polishing liquid absorbed in the water-absorbing sponge block 15 can be squeezed out. The fluororubber film 26 can be used to dip the polishing liquid. When the polishing liquid is dipped on the fluororubber film 26, the abrasive in the polishing liquid and the frosting 27 at the bottom of the fluororubber film 26 can be used to polish the heat transfer corrugated plate 16. The fluororubber film 26 dipped in the polishing liquid in the water-absorbing sponge block 15 can assist the frosting 27 at the bottom of the fluororubber film 26 to polish the heat transfer corrugated plate 16, thereby improving the polishing efficiency of the heat transfer corrugated plate 16.

[0055] While the heat transfer corrugated plate 16 is being polished, the piston rods of the two first electric telescopic rods 4 are retracted to move the two mounting plates 5 downward, thereby mobilizing the shell 13, the cured PE plastic particles 36 in the shell 13, and the fluororubber film 26 to move downward to generate a downward force on the heat transfer corrugated plate 16, thereby ensuring the contact strength between the fluororubber film 26 and the heat transfer corrugated plate 16, and ensuring the polishing efficiency of the heat transfer corrugated plate 16.

[0056] After the heat transfer corrugated plate 16 in the limit groove 34 is polished, the second electric telescopic rod 35 is started, and the piston rod of the second electric telescopic rod 35 pushes the bearing plate 33 to move upward until the upper surface of the bearing plate 33 is flush with the upper surface of the unloading platform 18 and then stops, and the piston rod of the first electric telescopic rod 4 is used again to drive the mounting plate 5 to move downward, so that the shell 13, the solidified PE plastic particles 36 in the shell 13 and the fluororubber film 26 generate a downward squeezing force on the polished heat transfer corrugated plate 16, and the friction between the fluororubber film 26 and the heat transfer corrugated plate 16 is greater than the friction between the heat transfer corrugated plate 16 and the heat transfer corrugated plate 16. The friction between the bearing plates 33 is generated, and the electric slider 3 is started at this time. The electric slider 3 slides horizontally on the guide rail 2, so that the fluororubber membrane 26 drives the polished heat transfer corrugated plate 16 to move horizontally, and the polished heat transfer corrugated plate 16 can be moved horizontally to the unloading table 18, and the automatic unloading of the polished heat transfer corrugated plate 16 can be automatically completed. The device can be used to automatically load, limit and unload the heat transfer corrugated plate 16, thereby improving the automation degree of the device when polishing the heat transfer corrugated plate 16, and improving the polishing efficiency of the heat transfer corrugated plate 16.
