When the threaded rod 83 rotates, it drives the slide plate 62 to move. The threaded rod 83 is connected to the slide plate 62 by a threaded rod 83. The front end of the threaded rod 83 is fixed with a handle 84. Rotating the handle 84 causes the threaded rod 83 to drive the slide plate 62 to move back and forth through the threaded connection with the mounting cylinder 81, thereby controlling the width of the discharge port below the storage box 71.

[0040] Furthermore, such as Figure 3 As shown, a first mounting frame 91 is fixedly connected to two support plates 31 at the rear of the first coating roller 34. The first heating element includes a first infrared lamp 92 located at the top of the first mounting frame 91. A second mounting frame 93 is fixedly connected to the two support plates 31 at the rear of the upper roller assembly 4. A second infrared lamp 94 is located at the bottom of the second mounting frame 93. A switch and a power supply are provided on the outside of the base 1. The first infrared lamp 92 and the second infrared lamp 94 are electrically connected to the power supply through the switch.

When it is necessary to add and replenish the paint in the storage tank 21, the paint is added to the collection box 23. The paint added to the collection box 23 flows into the storage tank 21 through the second feed port 24 and the first feed port 22, thereby replenishing the paint in the storage tank 21.

[0042] Example 3

[0043] The bottom strip double-sided coating difference treatment equipment provided in Examples 1 and 2 has been further optimized, such as... Figure 3 and Figure 4 As shown, the storage box 71 is specifically shaped with a wider top and a narrower bottom. The shape of the storage box 71 helps to guide the paint inside the storage box 71 towards the bottom discharge port, thereby avoiding paint residue in the corners of the storage box 71 and reducing the occurrence of right angles, thus making it easier to clean.

[0044] Furthermore, such as Figure 2 ,Figure 3 、 Figure 4 and Figure 5 As shown in the drawings, the sliding frame 61 is fixed to the downward inclined surface at the front end of the storage box 71, the inclined surface is formed by the shape of the storage box 71 being wide at the top and narrow at the bottom, for guiding the paint to flow downward, the connecting groove 72 and the sliding plate 62 are arranged obliquely, so that the sliding plate 62 is obliquely located inside the discharge port, the oblique of the sliding plate 62 can have a longer adjusting path inside the discharge port, so that the user can control the width and narrowness of the discharge port at the bottom end of the storage box 71 by rotating the handle 84 more subtly, so as to more accurately control the flow of the coating liquid.

[0045] The use process of the double-sided coating film differential processing equipment for bottom strip is as follows:

[0046] When the double-sided coating film processing of the bottom strip is needed, the bottom strip is placed between the first paint roller 34 and the second paint roller 42, then the motor 32 is started to drive the bottom strip to pass between the second paint roller 42 and the first paint roller 34, then the first conveying belt 11 and the second conveying belt 12 are started to drive the bottom strip to move, and the motor 32 is started to drive the second paint roller 42 to rotate, so that the first paint roller 34 at the bottom end is passively rotated by the contact of the bottom strip and the first paint roller 34;

[0047] The rotation of the first paint roller 34 makes the surface in contact with the paint below roll up, so as to coat the bottom strip, the paint in the storage box 71 falls through the discharge port to the second paint roller 42, the rotation of the second paint roller 42 makes the surface with paint contact with the bottom strip, so as to coat the bottom strip; the first infrared lamp 92 and the second infrared lamp 94 are started by the switch to dry the bottom strip after coating.

[0048] When the amount of the discharge port below the storage box 71 needs to be controlled to control the thickness of the coating film on the bottom strip by the second paint roller 42, the handle 84 is rotated to drive the sliding plate 62 to move through the threaded rod 83 and the mounting cylinder 81, so as to control the width of the discharge port, thereby controlling the speed and amount of the discharge port; when the sliding plate 62 moves backward, the discharge port becomes narrower, thereby reducing the flow of the discharge, and the amount of the coating film on the bottom strip by the second paint roller 42 becomes less, thereby controlling the thickness of the coating film.

[0049] In the utility model, unless there is definite stipulation and limitation, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrated; it can be mechanical connection, or electrical connection or communication with each other; it can be directly connected, or indirectly connected through an intermediate medium, it can be the communication or interaction relationship between two elements, unless otherwise specified.
