Description

Technical Field

[0001] This utility model relates to the field of polycarbonate board production technology, specifically to a cooling device for polycarbonate board production. Background Technology

[0002] Polycarbonate sheets are a type of polymer material made from polycarbonate polymers. Polycarbonate sheets have excellent transparency, with a visible light transmittance of up to 90%, making them suitable as building decoration materials. They possess outstanding impact resistance, high tensile strength, flexural strength, elongation at break, and rigidity. They also exhibit good heat and cold resistance, allowing for use in extreme temperatures. In the production process, dried polycarbonate sheets are fed into an extruder and then melt-extruded using a single-screw or twin-screw extruder. The molten polycarbonate passes through the extruder die to form the initial shape of the sheet. After extrusion, the sheet needs to be cooled by a polycarbonate sheet production cooling device.

[0003] The "Cooling Device for Optical Grade Polycarbonate Sheets" in the authorization announcement number "CN113492506B" achieves cooling of polycarbonate sheets through the setting of air-cooling and water-cooling structures, and uses a drying fan to make the coolant on the sheet evaporate quickly to avoid affecting the cooling work in the next stage. However, since the water-cooling structure continuously sprays coolant on the sheet, the drying fan may not be able to ensure that the coolant on the sheet is completely removed. Polycarbonate sheets with coolant adhering to their surface may affect the next process. Therefore, a cooling device for polycarbonate sheet production is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a cooling device for the production of polycarbonate sheets, so as to solve the problem that polycarbonate sheets with coolant adhering to their surface may affect the next process.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cooling device for polycarbonate sheet production includes a polycarbonate sheet production cooling machine and bolts. The polycarbonate sheet production cooling machine includes a base, a cooling trough with a built-in air-cooling structure, and a water-cooling device. The cooling trough is installed on the top of the base, and the water-cooling device is installed on the top of the cooling trough. Evenly spaced support legs are arranged on the outer side of the base. Two symmetrically arranged frames with built-in drive devices are installed on the top of the support legs. A mounting shaft is installed between the frames. A first roller is fixedly connected to the outer side of the mounting shaft. Evenly spaced electric telescopic rods are installed on the top of the frames. A connecting block is fixedly connected to the top of the electric telescopic rod. A connecting shaft is rotatably connected to the inner side of the connecting block. Two connecting shafts form a group. A second roller is fixedly connected between the group of connecting shafts. Evenly spaced first mounting blocks are fixedly connected to the outer sides of both the first and second rollers. A second mounting block is arranged on the outer side of the first mounting block. A sponge sleeve is fixedly connected to the outer side of the second mounting block. Evenly spaced fans are installed on the top of the frames.

[0007] Preferably, some of the sponge sleeves are symmetrically arranged on the outside of the first roller, and another portion of the sponge sleeves are symmetrically arranged on the outside of the second roller.

[0008] Preferably, the second roller is disposed on top of the first roller, and the first roller is evenly disposed between the two frames.

[0009] Preferably, there are several fans, and the fans are located on the outside of the electric telescopic rod.

[0010] Preferably, the first mounting block and the second mounting block are detachably connected by bolts, and the sponge sleeve is arc-shaped.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, a structure consisting of a mounting shaft, a first roller, a connecting shaft, a second roller, a sponge sleeve, and a fan is used. A rotatable first roller and a second roller are mounted on the outside of the polycarbonate sheet production cooling machine. Replaceable sponge sleeves are installed on the outer sides of both the first and second rollers. After cooling, the polycarbonate sheet moves between the first and second rollers. The sponge sleeves on the outer sides of the first and second rollers can absorb the coolant adhering to the outer surface of the polycarbonate sheet. The fan accelerates the evaporation of the coolant, thus solving the problem that polycarbonate sheets with coolant adhering to their surface may affect the next process. Attached Figure Description

[0025] Please see the appendix Figure 1-5 This utility model provides a technical solution:

[0026] A cooling device for polycarbonate sheet production includes a polycarbonate sheet production cooling machine 1 and bolts 12. The polycarbonate sheet production cooling machine 1 includes a base 101, a cooling tank 102 with a built-in air-cooling structure, and a water-cooling device 103. The cooling tank 102 is installed on the top of the base 101, and the water-cooling device 103 is installed on the top of the cooling tank 102. Support legs 2 are evenly arranged on the outer side of the base 101. Two symmetrically arranged frames 3 with built-in drive devices are installed on the top of the support leg 2. A mounting shaft 4 is installed between the frames 3. A first roller 5 is fixedly connected to the outer side of the mounting shaft 4. Electric telescopic rods 6 are evenly arranged on the top of the frame 3. A connecting block 7 is fixedly connected to the top of the electric telescopic rod 6. A connecting shaft 8 is rotatably connected to the inner side of the connecting block 7. Two connecting shafts 8 form a group. A second roller 9 is fixedly connected between the group of connecting shafts 8. A first mounting block 10 is evenly arranged on the outer side of both the first roller 5 and the second roller 9. A second mounting block 11 is arranged on the outer side of the first mounting block 10. A sponge sleeve 13 is fixedly connected to the outer side of the second mounting block 11. Fans 14 are evenly arranged on the top of the frame 3. This arrangement allows the sponge sleeve 13 to effectively absorb the coolant on the outer side of the plate. The blowing action of the fan 14 can accelerate the evaporation rate of the coolant and further reduce the residue of coolant on the surface of the plate.

[0027] Some of the sponge sleeves 13 are symmetrically arranged on the outer side of the first roller 5, and another portion of the sponge sleeves 13 are symmetrically arranged on the outer side of the second roller 9. This arrangement allows the sponge sleeves 13 to rotate with either the first roller 5 or the second roller 9. The second roller 9 is located on top of the first roller 5, which is evenly distributed between the two frames 3. This arrangement allows the second roller 9 and the first roller 5 to work together. There are several fans 14, which are located on the outer side of the electric telescopic rod 6. This arrangement allows the fans 14 to further reduce coolant residue on the surface of the sheet metal. The first mounting block 10 and the second mounting block 11 are detachably connected by bolts 12. The sponge sleeves 13 are arc-shaped, which allows for easy replacement of the sponge sleeves 13.

[0028] Workflow: All electrical components in this invention are equipped with an external power supply or a built-in battery. When the polycarbonate sheet is to be cooled by the polycarbonate sheet production cooling machine 1, the polycarbonate sheet is placed in the cooling tank 102 installed on the top of the base 101. The air-cooling structure built into the cooling tank 102 cools the polycarbonate sheet, and at the same time, the water-cooling device 103 also cools the polycarbonate sheet again. The workflow and principle can be found in the authorized announcement number "CN113492506B" "A Cooling Device for Optical Grade Polycarbonate Sheets". After the polycarbonate sheet production cooling machine 1 has finished cooling the polycarbonate sheet, there may be some coolant that has not been completely removed adhering to the polycarbonate sheet. After the polycarbonate sheet is detached from the cooling tank 102, it will move to the frame 3. The frame 3 is supported by the support legs 2. Before this, The height of the second roller 9 and its outer sponge sleeve 13 needs to be adjusted according to the thickness of the polycarbonate sheet. The electric telescopic rod 6 is activated via an external control device, and the fan 14 is powered, causing the electric telescopic rod 6 to extend and retract according to the actual situation. The electric telescopic rod 6 drives the connecting block 7, connecting shaft 8, second roller 9, and the sponge sleeve 13 on the outer side of the second roller 9 to move. Once the second roller 9 and the sponge sleeve 13 on the outer side of the second roller 9 have moved to the appropriate position, the electric telescopic rod 6 is deactivated, preventing further extension and retraction. The drive device inside the frame 3 drives the mounting shaft 4 to rotate, which in turn drives the first roller 5 and the sponge sleeve 13 on the outer side of the first roller 5 to rotate. The polycarbonate sheet will then contact the sponge sleeve 13 on the outer side of the first roller 5 and the second roller 9, causing the first roller 5 to move. The sponge sleeve 13 has good adsorption properties and can effectively adsorb the coolant on the outer side of the sheet. The blowing action of the fan 14 can accelerate the evaporation rate of the coolant, further reducing coolant residue on the sheet surface. When the sponge sleeve 13 needs to be replaced, remove the corresponding bolt 12 so that the bolt 12 no longer limits the first mounting block 10 and the second mounting block 11. Then the sponge sleeve 13 can be moved towards the first roller 5 or the second roller 9 to remove the sponge sleeve 13. The opposite operation can be used to install the sponge sleeve 13.

[0029] 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.
