Technical Field

[0001] The utility model relates to the technical field of PET sheet processing, in particular to a PET sheet cooling calendering roller group. Background Art

[0002] The components of PET sheets mainly include polyethylene terephthalate PET and polybutylene terephthalate PBT. PET plastic has excellent optical properties and weather resistance. Amorphous PET plastic has good optical transparency. PET plastic has excellent wear resistance, friction resistance, dimensional stability and electrical insulation. During the production and processing of PET sheets, calendering treatment will be performed to make their surface smoother.

[0003] When calendering the PET sheet, some dust will inevitably appear on the surface of the PET sheet. However, when cleaning the surface of the PET sheet, general cleaning brushes and other cleaning structures will inevitably cause scratches on the surface of the PET sheet. However, if the dust and other impurities on the PET sheet cannot be removed well, it may affect the subsequent processing of the PET sheet. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a PET sheet cooling and calendering roller group to solve the problem mentioned in the above background technology that when the PET sheet is calendered, some dust will inevitably appear on the surface of the PET sheet, but when the surface of the PET sheet is cleaned, general cleaning brushes and other cleaning structures will inevitably cause scratches on the surface of the PET sheet, but if the dust and other impurities on the PET sheet cannot be removed well, it may affect the subsequent processing of the PET sheet.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a PET sheet cooling calendering roller group, comprising a base plate, four supporting legs are fixedly installed on the bottom of the base plate, the four supporting legs are arranged in a rectangular array at the bottom of the base plate, a mounting frame is fixedly installed at the front end position of the upper surface of the base plate, a support rod is fixedly installed on the upper surface of the base plate at a position directly below the mounting frame, a first zoom rod is fixedly installed on the inner wall of the upper end of the mounting frame, mounting plates are fixedly installed at the end points of the support rod and the first zoom rod, and a sponge pad is arranged on the end surface of the mounting plate.

[0006] By adopting the above technical solution, the first zoom rod installed in the mounting frame is controlled to drive the mounting plate installed at the bottom zoom end to descend, and then the first zoom rod is stopped when the first zoom rod drives the mounting plate to descend to the required degree. Then, when the PET sheet passes between the first zoom rod and the mounting plate installed on the support rod, the sponge pad installed on the mounting plate will scrape off some dust attached to the surface of the PET sheet, thereby preventing more dust and impurities from being attached to the PET sheet and affecting subsequent production.

[0008] By adopting the above technical solution, the second zoom rod installed in the support frame will drive the first connecting frame installed at its bottom zoom end to descend, and then the first connecting frame will drive the pressing roller installed at its bottom to descend and cooperate with the pressing roller installed on the second connecting frame to calender the PET sheet.

[0009] Preferably, a water storage cavity for storing water is provided inside the pressing roller, and a waterproof cover is provided on the surface of the pressing roller.

[0010] By adopting the above technical solution, a certain amount of water can be stored by arranging a water storage chamber inside the pressing roller, and a waterproof cover is arranged outside the pressing roller, which can make the pressing roller cool the PET sheet when calendering the PET sheet.

[0012] By adopting the above technical solution, the hand-cranked wheel is rotated to drive the threaded rod to rotate, and then when the threaded rod rotates, it will drive the sliding block to move left and right on the fixed frame. Then, because the sliding block is mounted on the fixed frame, the fixed frame can limit the sliding block. Then, the third zoom rod installed at the bottom of the control sliding block is lowered, so that the limit plate installed at the zoom end of the third zoom rod can limit the PET sheet to prevent the PET sheet from deviating during movement.

[0014] By adopting the above technical scheme, the interior of the hollow plate is a hollow structure and a certain amount of water can be stored inside. Then, the water pump is turned on to drive the connecting pipe to pump water from the water tank, and then the water is sent into the hollow plate. Then, when the water flows in the hollow plate, it returns to the water tank through the circulation pipe. Therefore, when the PET sheet passes through the hollow plate, the water in the hollow plate will take away the heat on the PET sheet, thereby cooling the PET sheet, thereby eliminating the trouble of sending the PET sheet to external equipment for washing and cooling, and improving production efficiency.

[0027] Working principle: The four supporting legs 2 installed at the bottom of the bottom plate 1 are convenient for supporting the structure. When the PET sheet needs to be calendered, some impurities will inevitably adhere to the PET sheet. Then, the first zoom rod 5 installed in the mounting frame 3 is controlled to drive the mounting plate 6 installed at the bottom zoom end to descend. Then, when the first zoom rod 5 drives the mounting plate 6 to descend to the required degree, the first zoom rod 5 is stopped. Then, when the PET sheet passes between the first zoom rod 5 and the mounting plate 6 installed on the support rod 4, the sponge pad 7 installed on the mounting plate 6 will scrape off some dust attached to the surface of the PET sheet, thereby preventing more dust from adhering to the PET sheet. Dust and impurities will affect the subsequent production. Since the sponge pad 7 is relatively soft, it will not damage the surface of the PET sheet. After the PET sheet is calendered, the hand wheel 18 is turned to drive the threaded rod 17 to rotate. When the threaded rod 17 rotates, it will drive the sliding block 19 to move left and right on the fixed frame 15. Since the sliding block 19 is mounted on the fixed frame 15, the fixed frame 15 can limit the sliding block 19. Then, the third zoom rod 20 installed at the bottom of the control sliding block 19 is lowered, so that the limiting plate 21 installed at the zoom end of the third zoom rod 20 limits the PET sheet to prevent the PET sheet from running off when moving.

Then, a water storage chamber 13 is arranged in the pressing roller 12 to store a certain amount of water. At the same time, a waterproof cover 14 is arranged outside the pressing roller 12 to enable the pressing roller 12 to cool the PET sheet when calendering the PET sheet. Then, the pressing plate enters To the central control board in the vertical board 22, and then because the interior of the hollow board 23 is a hollow structure, it can store a certain amount of water, and then turn on the water pump 26 to drive the connecting pipe 25 to pump water from the water tank 24, and then send the water into the hollow board 23, and then when the water flows in the hollow board 23, it returns to the water tank 24 through the circulation pipe 27.
