It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0025] Some embodiments of this utility model are described below with reference to the accompanying drawings.
[0026] Example 1:
[0027] Combination Figure 1-5 As shown, this embodiment provides a pressing and molding equipment for producing release film, including: a main body 100 and a cleaning mechanism 200.
[0028] The main structure 100 includes a frame 110, a first steel rod 120 rotatably mounted on the frame 110, a horizontal plate 130 fixed to the top of the frame 110, a pressing assembly 140 passing through the horizontal plate 130, multiple cylinders 150 fixed to the top of the horizontal plate 130, a movable rod 160 disposed in the inner cavity of the cylinder 150 and whose bottom end passes through the horizontal plate 130 and is fixedly connected to the pressing assembly 140, an air inlet 170 installed on one side of the cylinder 150, a main air inlet pipe 180 disposed on one side of the cylinder 150 and communicating with the multiple air inlets 170, and a pressure sensor 190 installed at the top of the cylinder 150 and extending into the inner cavity of the cylinder 150.
[0029] The frame 110 is U-shaped and is used to install other components. The first steel rod 120 is rotatably mounted on the inner side of the frame 110 and works with the pressing component 140 to press and shape the release film.
[0030] The horizontal plate 130 is fixedly connected to the frame 110 at both ends. The pressing assembly 140 is used to press and shape the release film. It includes two guide rods 141 that move through the horizontal plate 130, a U-shaped plate 142 fixed to the bottom of the guide rods 141, a second steel rod 143 rotatably mounted on the opposite inner side of the U-shaped plate 142, and a first motor 144 fixed to one side of the U-shaped plate 142 and whose shaft is fixedly connected to the second steel rod 143. There are round holes on both sides of the horizontal plate 130. The guide rods 141 move through the round holes and can limit the movement of the U-shaped plate 142 to ensure the stability of the U-shaped plate 142 when it moves up and down. The U-shaped plate 142 is used to install the second steel rod 143. The second steel rod 143 corresponds to the first steel rod 120 and is used to press the release film. The first motor 144 is used to drive the second steel rod 143 to rotate.
[0031] The cylinder 150 is fixed to the top of the horizontal plate 130. The movable rod 160 includes a piston 161 movably disposed in the inner cavity of the cylinder 150 and a support rod 162 with one end fixedly connected to the piston 161 and the other end passing through the horizontal plate 130 and fixedly connected to the U-shaped plate 142. With this arrangement, when the inner cavity of the cylinder 150 is filled with high-pressure gas, the movable rod 160 drives the pressing assembly 140 to press down under the action of air pressure, ensuring the pressing force of the pressing assembly 140. At the same time, the pressure of the pressing assembly 140 can be adjusted by adjusting the air pressure in the cylinder 150.
[0032] The air inlet pipe is used to send high-pressure gas into the inner cavity of the cylinder 150. It includes a branch pipe 171 connecting the inner cavity of the cylinder 150 and the main air inlet pipe 180, and an electric valve 172 installed on the branch pipe 171. One end of the main air inlet pipe 180 is connected to the air pump, and the other end is closed. High-pressure air can be sent into the inner cavity of the cylinder 150 through the main air inlet pipe 180 and the branch pipe 171. The electric valve 172 is used to control the opening and closing of the branch pipe 171. The air pressure sensor 190 is used to monitor the air pressure in the inner cavity of the cylinder 150 in real time and close the electric valve 172 after the air pressure reaches the set value.
[0033] The cleaning mechanism 200 is used to clean dust and impurities on the surface of the second steel rod 143. It includes a housing 210 fixed to one side of the pressing assembly 140, a cleaning component 220 installed on the inner wall of the housing 210, a plurality of blowers 230 installed on the top of the housing 210, a filter screen 240 provided on the top of the blower 230, and a retaining ring 250 installed on the top of the blower 230 by thread engagement.
[0034] The housing 210 has an L-shaped cross-section, with one end fixed to the U-shaped plate 142. The cleaning component 220 includes a brush roller 221 rotatably mounted on the inner wall of the housing 210 and a second motor 222 mounted on one side of the housing 210 with its shaft fixedly connected to the end of the brush roller 221. The brush roller 221 is pressed against the surface of the second steel rod 143. When the second motor 222 is started, it drives the brush roller 221 to rotate. The rotation of the brush roller 221 can brush away the dust and impurities attached to the surface of the second steel rod 143.
[0035] The blower 230 includes a tube 231 fixed to the top of the housing 210 and communicating with the inner cavity of the housing 210, and a high-speed fan 232 installed on the inner wall of the tube 231. When the high-speed fan 232 is started, it can discharge the air in the inner cavity of the housing 210 through the tube 231. At the same time as the air is discharged, it can also drive the dust and impurities brushed off by the brush roller 221 in the inner cavity of the housing 210 to be discharged, so as to prevent the dust and impurities from adhering to the steel rod again.
[0036] The filter screen 240 is a HEPA filter paper that filters dust and impurities in the exhaust air. The retaining ring 250 is used to fix the filter screen 240 and is installed at the top of the tube body 231 by a threaded connection, which facilitates the replacement of the filter screen 240.
[0037] The working principle and usage process of this utility model are as follows: During use, the release film to be pressed is passed between the first steel roller 120 and the second steel roller 143. The pressing force of the second steel roller 143 is adjusted according to process requirements. The electric valve 172 is opened, and high-pressure air is then introduced into the inner cavity of the cylinder 150 through the main air inlet pipe 180 and the branch pipe 171, filling the inner cavity of the cylinder 150 with high-pressure gas. Simultaneously, the air pressure sensor 190 monitors the air pressure value inside the cylinder 150 in real time. When the air pressure inside the cylinder 150 is the same as the set air pressure, the electric valve 172 is closed. At this time, the gas... Under pressure, the movable rod 160 drives the pressing component 140 to press down, ensuring the pressing force of the pressing component 140. The first motor 144 starts, driving the second steel roller 143 to rotate, rotating the release film. In addition, during the rotation of the second steel roller 143, the second motor 222 starts, driving the brush roller 221 to rotate, removing dust and impurities attached to the steel roller. The blower 230 starts, expelling the air from the inner cavity of the housing 210. At this time, dust and impurities are discharged outward with the airflow and filtered by the filter screen 240, realizing the collection of dust and impurities.
