[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0034] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0035] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a multi-film coating unit.

[0036] Example 1:

[0037] Combination Figures 1-5As shown, the present invention provides a multi-film coating unit, including a printing and coating mechanism 100, two sets of expansion mechanisms 200 disposed on the printing and coating mechanism 100, two sets of sheet material fitting mechanisms 300 disposed on the printing and coating mechanism 100, and a coating mechanism 400 disposed outside the printing and coating mechanism 100. The printing and coating mechanism 100 is used to provide effective bearing capacity for materials of different sizes, the expansion mechanisms 200 are used to provide fitting clamping force for materials with different shaped ends, the sheet material fitting mechanisms 300 are used to increase the bearing pressure for materials of different sizes, and the coating mechanism 400 is used to increase the coating pressure for materials of different sizes.

[0038] The printing and laminating mechanism 100 includes a base 110, a limiting plate 120 installed at the bottom of the base 110, two clamps 130 installed on the side of the base 110, a first lead screw 140 movably installed in the two clamps 130, and a pressure plate 150 movably installed between the base 110 and the limiting plate 120, wherein the first lead screw 140 is adapted to be installed in a threaded hole at the outer end of the pressure plate 150.

[0039] The other end of the pressure plate 150 is provided with two end plates, and a first pull plate 160 is movably connected to each of the two end plates;

[0040] A T-shaped plate 170 is movably installed at the other end of the first pull plate 160;

[0041] Two symmetrically distributed second pull plates 180 are movably installed on the T-shaped plate 170;

[0042] The expansion mechanism 200 includes a base 210 installed at the outer end of the base 110, two other extrusion plates 220 movably installed inside the base 210, two insertion plates 230 installed in two insertion holes inside the base 210, and a spring 240 provided in a sliding groove inside the extrusion plate 220.

[0043] The plate fitting mechanism 300 includes a first pad 310 disposed at one end of the base 110, a second pad 320 disposed at the other end of the base 110, a side-bent main plate 330 connected to the first pad 310, a side-bent secondary plate 340 connected to the second pad 320, and two base supports 350 installed at the bottom of the first pad 310 and the second pad 320, with pulleys 360 movably installed in the base supports 350.

[0044] Two second lead screws 370 are movably installed in the end plates at two locations on the outer side of the base 350;

[0045] One of the second lead screws 370 is provided with a right-angle limiting plate 380, and the other second lead screw 370 is provided with an arc-angle limiting plate 390;

[0046] The coating mechanism 400 includes two scrapers 450 with varying widths.

[0047] After the printing material is placed on top of the base 110, the first lead screw 140 is adjusted to rotate clockwise according to the size of the material. At this time, the first lead screw 140 will push the pressure plate 150 to move outward laterally. Finally, the pressure plate 150 will pull the two first pull plates 160 to contract towards the middle of the base 110. Finally, the two T-shaped plates 170 will be compressed and expand outward. At this time, the two sets of second pull plates 180 will push the four extrusion plates 220 to expand outward at equal intervals. Finally, the two slide rails 410 will be compressed and move outward.

[0048] As the two slide rails 410 expand, the two sets of plate fitting mechanisms 300 will also extend. At this time, the two sets of plate fitting mechanisms 300 can limit and clamp large-sized materials, and selectively push the right-angle limiting plate 380 or the arc-angle limiting plate 390 upward by adjusting the clockwise rotation of the two second lead screws 370. At this time, materials with different shaped ends can be effectively constrained. With the further descent of the two scrapers 450 and the overall movement of the printing and coating mechanism 100, the gradient-sized materials can finally be effectively coated.

[0049] Example 2:

[0050] Combination Figure 4 As shown, based on Embodiment 1, a pin is provided at the bottom of the extrusion plate 220, and the pin is movably installed in the hole at the outer end of the second pull plate 180.

[0051] Preferably, the end face of the outer end of the extrusion plate 220 is polished to reduce its frictional resistance with the inner wall of the slide rail 410. One end of the spring 240 is pressed against the inner wall of the extrusion plate 220, while the other end of the spring 240 is pressed against the inner wall of the insert plate 230.

[0052] Example 3:

[0053] Combination Figures 2-5 As shown, in the above embodiment, the coating mechanism 400 also includes a slide rail 410 disposed outside the extrusion plate 220, a suspension 420 mounted on the slide rail 410, a traction frame 430 movably mounted on the top of the suspension 420, and a horizontally placed truss 440 movably mounted on the bottom end of the traction frame 430.

[0054] Preferably, the slide rail 410, suspension 420, traction frame 430 and truss 440 are all made of stainless steel to provide sufficient compressive support for the scraper 450.

[0055] Truss 440 consists of two pads and crossbars, and scraper 450 is mounted on the crossbars;

[0056] The suspension 420 has a groove inside, and a first axle 460 is installed in the groove. The second axle 470 is installed in the traction frame 430.

[0057] A collet 480 is movably mounted on both the first shaft 460 and the second shaft 470, and a tension spring 490 is connected between the two collets 480.

[0058] The slide rail 410 has an I-shaped slide rail inside, and the pulley 360 consists of a vertical shaft and two rollers, and the pulley 360 is adapted to be installed in the I-shaped slide rail.

[0059] Preferably, the cross-section of the scraper 450 is tapered, and the dimensions of the two scrapers 450 need to be selected according to the pressure applied by the double film. When the surface of the substrate is soft, a rubber outer layer can be added to the outside of the scraper 450 to reduce wear on the fragile material.

[0060] The working principle and usage process of this utility model: During the use of the laboratory coating machine, some unexpected problems occurred. Due to the imbalance of coating speed of different sized substrates on the machine, and the different pressure surfaces of different sized materials on the machine, once the coating speed is unbalanced, the coating pressure will change to a certain extent, which will lead to uneven multi-film coating.

[0061] When the unit is in use, the first lead screw 140 is pre-adjusted to rotate clockwise. At this time, the first lead screw 140, which is positioned and clamped by the two clamps 130, will push the pressure plate 150 to move outward laterally. Finally, the other end of the pressure plate 150 will pull the two first pull plates 160 to retract towards the middle of the base 110. At this time, the two T-shaped plates 170 and the two sets of T-shaped plates 170 will be compressed and expand outward. At this time, the extrusion plate 220 connected to the other end of the T-shaped plate 170 will extend outward along the slide rail inside the base 210. As the four extrusion plates 220 expand outward at the same time, the two slide rails 410 will be compressed and expand outward.

[0062] As the two adjacent suspensions 420 extend outward, the two traction frames 430 will eventually push the truss 440 downward, and the scraper 450 set on the truss 440 can adapt and pressurize the larger printing material.

[0063] When the two sets of plate fitting mechanisms 300 work together with the printing and coating mechanism 100 to move back and forth along the inner side of the two slide rails 410, the material constrained by the two sets of plate fitting mechanisms 300 can be effectively coated. By setting the size of the two scrapers 450 to a gradient structure, the unit can perform double film pressure coating on the surface of the printing material.

[0064] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
