[0031] Specifically, by starting the motor 23, the threaded rod 8 rotates, and the slider 19 moves left and right along the outer surface of the threaded rod 8, thereby driving the fixed plate 18 and the rolling roller 10 to move synchronously. At this time, by starting the air pump 4, 18 is driven to move downward, and the rolling roller 10 is brought into contact with the outer surface of the pre-coated film to apply the coating. After the coating work is completed, the blower 22 is turned on to suck the outside air into the interior of the heating box 3, and the hot air is formed after being heated by the electric heating wire inside the heating box 3, and finally ejected through the hot air pipe 14. As the fixed plate 18 reciprocates left and right, the pre-coated film is evenly dried, reducing the drying time of the coating, thereby improving the speed and efficiency of the production line, thereby increasing production.
[0032] Reference Figure 1 , Figure 4 The pressing assembly includes two mounting shells 5, which are respectively fixedly connected to the left and right sides of the mounting bracket 2. The interior of the mounting shell 5 is rotatably connected to a bidirectional screw 501, and the external threaded connection of the bidirectional screw 501 is connected to two threaded sleeves 502. The bottom end of the threaded sleeve 502 is rotatably connected to a sliding frame 6, and the bottom end of the sliding frame 6 is rotatably connected to a covering plate 7. The outer surface of the mounting shell 5 is fixedly connected to a motor 24, and the output end of the motor 24 is connected to the bidirectional screw 501.
[0033] Specifically, start motor 24, and drive the bidirectional screw 501 inside the mounting shell to rotate. At this time, the two threaded sleeves 502 will approach each other along the outer wall of the bidirectional screw, thereby driving the top end of the sliding frame 6 to swing. At this time, under the traction force of the sliding frame 6, the heat delivery pipe 7 is driven to move downward until the film is clamped, ensuring that the position of the film does not change during the coating process.
[0034] Reference Figure 1 , Figure 3The inner bottom wall of the fixed plate 18 is fixedly connected to the transport pump 12, the output end of the transport pump 12 is fixedly connected to the material guide pipe 21, the input end of the transport pump 12 is fixedly connected to the transport pipe 13, the inner left side of the fixed plate 18 is fixedly connected to the material barrel 11, one end of the material guide pipe 21 is fixedly connected to the spray pipe 16, the outer surface of the spray pipe 16 is fixedly connected to a plurality of nozzles, and the bottom end of the fixed plate 18 is installed with a rolling roller 10.
[0035] Specifically, by starting the transport pump 12, one end of the transport pipe 13 is connected to the interior of the barrel 11, so that the material liquid in the barrel 11 is drawn into the interior of the spray pipe 16. The spray pipe 16 has multiple small holes, which are sprayed on the outer surface of the rolling roller 10. In addition, by starting the motor 23, the threaded rod 8 rotates. At this time, the slider 19 will move left and right along the outer surface of the threaded rod 8, thereby driving the fixed plate 18 and the rolling roller 10 to move synchronously. At this time, by starting the air pump 4, the fixed plate 18 is driven to move downward, and the rolling roller 10 is brought into contact with the outer surface of the film to apply it.
[0036] Reference Figure 2 The outer surface of the mounting bracket 2 is fixedly connected with a motor 23 , the outer surface of the motor 23 is provided with a threaded rod 8 , and the output end of the motor 23 is fixedly connected to one end of the threaded rod 8 .
[0037] Specifically, by starting the motor 23, the rotation of the motor 23 drives the threaded rod 8 to rotate, and the slider 19 moves left and right along the outer surface of the threaded rod 8, thereby driving the fixed plate 18 and the rolling roller 10 to move synchronously.
[0038] Reference Figure 4 The cross section of the threaded sleeve 502 is square, and the outer surface of the threaded sleeve 502 fits with the inner wall of the mounting shell 5 .
[0039] Specifically, the cross-section of the threaded sleeve 502 is square, and the threaded sleeve 502 can better fit the inner wall of the mounting shell 5. When the bidirectional screw 501 rotates, the threaded sleeve 502 can move along the inner wall of the mounting shell 5, ensuring that the bidirectional screw 501 will not rotate during the movement, thereby ensuring the stability of the bidirectional screw 501 during the movement.
[0040] Reference Figure 3 One end of the transport pipe 13 is connected to the interior of the barrel 11.
[0041] Specifically, by starting the transport pump 12 , one end of the transport pipe 13 is communicated with the interior of the barrel 11 , so that the material liquid in the barrel 11 is drawn into the interior of the spray pipe 16 .
[0042] Reference Figure 2The interior of the rear side slide groove 15 is fixedly connected with a sliding rod 9, and the outer surface of the sliding rod 9 is slidably connected with a sliding block 3 25, and the sliding block 3 25 is fixedly connected to the top of the connecting plate 26.
[0043] Specifically, there is a sliding rod 9 inside the rear side sliding groove 15, and the sliding block 3 25 can slide on the outer surface of the sliding rod 9, so that the air pump 4 can slide left and right better, and there is a sliding block 3 25 on the top of the connecting plate 26.
[0044] Reference Figure 2 The cross section of the slider 19 is set to be square, and the outer surface of the slider 19 is in contact with the inner wall of the slide groove 15.
[0045] Specifically, the cross section of the slider 19 is square, and the slider 19 can better fit the inner wall of the slide groove 15. When the threaded rod 8 rotates, the slider 19 can move along the inner wall of the slide groove 15, ensuring that the slider 19 will not rotate during the movement, thereby ensuring the stability of the slider 19 during the movement.
[0046] Working principle: When starting the pre-coating film production device, the staff first puts the film on the top of the base 1 and starts the motor 24. The motor 24 drives the bidirectional screw 501 inside the mounting shell to rotate. At this time, the two threaded sleeves 502 will approach each other along the outer wall of the bidirectional screw, thereby driving the top of the sliding frame 6 to swing. At this time, under the traction of the sliding frame 6, the heat delivery pipe 7 is driven to move downward until the film is clamped to ensure that the position of the film will not change during the coating process. At this time, the transport pump 12 is started to move the glue in the barrel 11. The liquid is transported to the guide pipe 21 through the transport pipe 13, and finally enters the inside of the spray pipe 16 evenly through the guide pipe 21. Since the inner wall of the spray pipe 16 is evenly covered with small holes, the liquid is sprayed on the outer surface of the rolling roller 10. In addition, by starting the motor 23, the threaded rod 8 rotates, and the slider 19 moves left and right along the outer surface of the threaded rod 8, thereby driving the fixed plate 18 and the rolling roller 10 to move synchronously. At this time, by starting the air pump 4, 18 is driven to move downward, so that the rolling roller 10 contacts the outer surface of the pre-coated film and applies the coating to it.
[0047] Finally, after the coating work is completed, turn on the blower 22 to suck the outside air into the interior of the heating box 3, and form hot air after being heated by the electric heating wire inside the heating box 3, and finally sprayed out through the hot air pipe 14. As the fixed plate 18 reciprocates left and right, the pre-coated film is evenly dried, reducing the drying time of the coating film, thereby improving the speed and efficiency of the production line, thereby increasing production.
[0048] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
