[0001] This utility model relates to the field of printing technology, specifically to a noise reduction device for PET film printing. Background Technology

[0002] PET film printing refers to a technique of printing on polyethylene terephthalate (PET) film. PET film is a common type of plastic film with excellent transparency, heat resistance, chemical stability, and good mechanical properties, making it widely used in electronics, packaging, displays, advertising, and other fields.

[0003] When printing traditional PET film, the film surface is not smooth enough, which will create gaps with the printing rollers and cause noise during the printing process. Printing machines usually lack sound insulation and noise reduction functions, which will cause noise pollution and affect the working environment of personnel.

[0004] Therefore, a noise reduction device for PET film printing is proposed. Utility Model Content

Printing machines usually lack sound insulation and noise reduction functions, which will cause noise pollution and affect the working environment of personnel.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A noise reduction device for PET film printing includes a printing table, a soundproof chamber fixedly installed on the top surface of the printing table, opening and closing mechanisms fixedly installed on both sides of the outer surface of the soundproof chamber, an opening and closing plate fixedly installed on one side of the opening and closing mechanism, sound insulation components fixedly installed on the inner walls of the soundproof chamber and the opening and closing plate, an mounting plate fixedly installed on one side of the top surface of the soundproof chamber, leveling components fixedly installed on both sides of the bottom surface of the mounting plate, and a tensioning mechanism fixedly installed in the middle of the bottom surface of the mounting plate.

[0008] As a further embodiment of this utility model: the opening and closing mechanism includes a hydraulic cylinder and a lifting block. The hydraulic cylinder is fixedly installed on the outer surface of the soundproof room, and the lifting block is fixedly installed at the output end of the hydraulic cylinder. Limiting grooves are opened on both sides of the top surface of the soundproof room, and the opening and closing plate is slidably installed inside the limiting groove. The opening and closing mechanism is used to open and close the soundproof room.

[0009] As a further embodiment of this utility model: the sound insulation component includes a sound insulation board and a microporous sound-absorbing board. The sound insulation board is fixedly disposed on the inner wall of the sound insulation chamber and the opening and closing plate, and the microporous sound-absorbing board is fixedly disposed on one side of the sound insulation board. The sound insulation component is used for sound insulation during the printing of PET film.

[0010] As a further embodiment of this utility model: the leveling component includes a connecting frame and an electrically heated leveling roller. The connecting frame is fixedly disposed on the bottom surface of the mounting plate, and the electrically heated leveling roller is rotatably disposed on one side of the connecting frame. A temperature controller for controlling the temperature of the electrically heated leveling roller is fixedly installed on one side of the top surface of the soundproof chamber. The leveling component is used to level the PET film.

[0011] As a further embodiment of this utility model: the tensioning mechanism includes a hydraulic rod, a lifting frame, and a tensioning roller. The hydraulic rod is fixedly installed in the middle of the bottom surface of the mounting plate, the lifting frame is fixedly installed at the output end of the hydraulic rod, and the tensioning roller is rotatably installed inside the lifting frame.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up the leveling components and tensioning mechanism, the PET film is wrapped in an S-shape around the surface of the electrically heated leveling roller and tensioning roller. The electrically heated leveling roller heats and softens the PET film, making it easier to shape. Opening the hydraulic rod drives the lifting frame and tensioning roller to rise and fall, so that the PET film can better adhere to the electrically heated leveling roller, and the surface of the PET film is leveled. This avoids noise caused by uneven film surface and gaps between the film and the printing roller during the printing process, which would also affect the printing quality.

[0016] 2. By setting up the opening and closing mechanism and sound insulation components, the hydraulic cylinder is opened, which causes the lifting block to drive the opening and closing plate to rise and fall, leaving a gap between the sound insulation chamber and the sound insulation chamber to facilitate the passage of film materials of different thicknesses. This allows the printing operation to be carried out in a relatively enclosed space. The microporous sound-absorbing panels set on the surface of the sound insulation chamber and the opening and closing plate can absorb the noise generated by printing. The sound insulation panels further insulate the sound, which greatly reduces the noise generated by PET film printing and creates a good working environment for the staff.

An opening and closing plate 4 is fixedly installed on one side of the opening and closing mechanism 3. Sound insulation components 5 are fixedly installed on the inner walls of the soundproof chamber 2 and the opening and closing plate 4. By setting the opening and closing mechanism 3 and the sound insulation components 5, the hydraulic cylinder 301 is opened, so that the lifting block 302 drives the opening and closing plate 4 to rise and fall, leaving a gap with the soundproof chamber 2 to facilitate the passage of film materials of different thicknesses, so that the printing operation is carried out in a relatively closed space. The microporous sound-absorbing plate 502 set on the surface of the soundproof chamber 2 and the opening and closing plate 4 can absorb the noise generated by printing. The sound insulation plate 501 further insulates the sound, greatly reducing the noise generated by PET film printing and creating a good working environment for the staff.

Through the setting of the flattening components 7 and the tensioning mechanism 8, the PET film is wrapped in an S-shape around the surface of the electric heating flattening roller 702 and the tensioning roller 803. The electric heating flattening roller 702 heats and softens the PET film, making it easier to shape. The hydraulic rod 801 is opened, which drives the lifting frame 802 and the tensioning roller 803 to rise and fall, so that the PET film can better adhere to the electric heating flattening roller 702, flattening the surface of the PET film and avoiding noise caused by uneven film surface and gaps between the film and the printing roller 11 during the printing process, which would also affect the printing quality.

[0027] like Figure 3 As shown, the opening and closing mechanism 3 includes a hydraulic cylinder 301 and a lifting block 302. The hydraulic cylinder 301 is fixedly installed on the outer surface of the soundproof chamber 2, and the lifting block 302 is fixedly installed at the output end of the hydraulic cylinder 301. Limit grooves are opened on both sides of the top surface of the soundproof chamber 2, and the opening and closing plate 4 is slidably installed inside the limit groove.

[0028] The opening and closing mechanism 3 serves to seal off the soundproof room 2.

[0029] like Figure 3 As shown, the sound insulation component 5 includes a sound insulation panel 501 and a microporous sound-absorbing panel 502. The sound insulation panel 501 is fixedly installed on the inner wall of the sound insulation chamber 2 and the opening and closing plate 4, and the microporous sound-absorbing panel 502 is fixedly installed on one side of the sound insulation panel 501.

[0030] The sound insulation component 5 absorbs the noise generated by the printed PET film.

[0031] like Figure 2 As shown, the leveling component 7 includes a connecting frame 701 and an electrically heated leveling roller 702. The connecting frame 701 is fixedly installed on the bottom surface of the mounting plate 6, and the electrically heated leveling roller 702 is rotatably installed on one side of the connecting frame 701. A temperature controller for controlling the temperature of the electrically heated leveling roller 702 is fixedly installed on one side of the top surface of the soundproof chamber 2.

[0032] The leveling component 7 is used to level the PET film.

[0033] like Figure 2 As shown, the tensioning mechanism 8 includes a hydraulic rod 801, a lifting frame 802, and a tensioning roller 803. The hydraulic rod 801 is fixedly installed in the middle of the bottom surface of the mounting plate 6, the lifting frame 802 is fixedly installed at the output end of the hydraulic rod 801, and the tensioning roller 803 is rotatably installed inside the lifting frame 802.

[0034] The tensioning mechanism 8 is designed to tension the PET film.

[0035] like Figure 5 As shown, an ink cartridge 9 is fixedly installed on one side of the top surface of the printing table 1, a servo motor 10 is fixedly installed on the outer surface of the soundproof chamber 2 near the ink cartridge 9, a printing roller 11 is fixedly installed at the output end of the servo motor 10, an electric push rod 12 is fixedly installed on the other side of the top surface of the soundproof chamber 2, a mounting frame 13 is fixedly installed at the output end of the electric push rod 12, and a pressure roller 14 is rotatably installed inside the mounting frame 13.

[0038] The observation window 15 is used to observe the printing status of the PET film.

[0039] The working principle of this utility model is as follows: opening the hydraulic cylinder 301 causes the lifting block 302 to drive the opening and closing plate 4 to rise and fall, leaving a gap with the soundproof chamber 2 to facilitate the passage of film materials of different thicknesses, so that the printing operation can be carried out in a relatively enclosed space.

[0040] The microporous sound-absorbing plate 502 installed on the surface of the soundproof chamber 2 and the opening and closing plate 4 can absorb the noise generated by printing, and the soundproof plate 501 further insulates the sound, greatly reducing the noise generated by PET film printing and creating a good working environment for the staff.

[0041] The PET film is wound in an S-shape onto the surfaces of the electrically heated leveling roller 702 and the tensioning roller 803. The electrically heated leveling roller 702 heats and softens the PET film, making it easier to shape. The hydraulic rod 801 is opened, which drives the lifting frame 802 and the tensioning roller 803 to rise and fall, so that the PET film can better adhere to the electrically heated leveling roller 702 and the surface of the PET film is flattened. This avoids noise caused by uneven film surface and gaps between the film and the printing roller 11 during the printing process, which would also affect the printing quality.
