Description

Technical Field

[0001] The utility model relates to the technical field of coating rollers, in particular to a pneumatic lifting coating roller. Background Art

[0002] Advertising cloth is a material used for outdoor and indoor advertising displays. Advertising cloth is widely used in various occasions, including outdoor advertising, exhibitions and events, commercial promotions, traffic advertising, and so on.

[0003] The manufacturing process of advertising cloth includes feeding the printed advertising cloth through a feeding roller, then passing it through a coating spray head. The coating hopper will evenly spray the pre-stored waterproof coating liquid on the surface of the advertising cloth through the spray head. Then the advertising cloth will pass through the coating roller device, and the coating roller will evenly apply the waterproof coating liquid on the surface of the advertising cloth. Then it will be dried through a drying oven, and finally it will be coiled and collected through a winding roller. In addition, a motor will be preset on the bracket of the winding roller to realize the electric conveying and winding process of the entire coating, drying, and winding of the advertising cloth.

[0004] Currently, the existing coating roller devices are generally divided into an upper coating roller and a lower coating roller, and there is a spacing between them to ensure that the advertising cloth can pass through. However, since the thickness of each advertising cloth is different, for the existing coating roller device for coating the waterproof coating on the surface of the advertising cloth, the spacing between the upper coating roller and the lower coating roller can mostly not be accurately and conveniently adjusted for advertising cloths of different thicknesses, which mostly reduces the pneumatic precision lifting application range of the coating roller device for coating the waterproof coating on the surface of the advertising cloth.

[0005] The above problems are widespread and urgently need to be improved. Content of the Utility Model

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0026] Refer to Figures 1-5 , a pneumatic lifting coating roller, including an upper coating roller 1. A lower roller frame 21 and a bottom plate 4 are provided below the upper coating roller 1. A first rack plate 6 and a second rack plate 7 are provided on the bottom plate 4. A coating motor 71 is provided between the upper coating roller 1 and the second rack plate 7. A lower coating roller 2 is rotatably arranged on the lower roller frame 21. An air compressor 41 and a lifting cylinder 43 are provided on the bottom plate 4. A pneumatic sliding rod 5 is slidably connected in the lifting cylinder 43. The pneumatic sliding rod 5 is fixedly arranged with the lower roller frame 21. A welding plate 3 is provided on the side wall of the lower roller frame 21. A guiding sliding opening 31 is opened on the welding plate 3. A smooth layer 311 is provided in the guiding sliding opening 31. A size scale plate 61 is arranged on the first rack plate 6. An identification pointer 22 and a lighting plate 23 are arranged on the lower roller frame 21. When the coating motor 71 is started, it drives the upper coating roller 1 to roll. Scale values are preset on the size scale plate 61, and the real - time size value can be indicated in real - time through the identification pointer 22.

[0027] The air compressor 41 is an air compressor. The air compressor 41, the lifting cylinder 43, and the pneumatic sliding rod 5 form a group, which is a prior art to achieve the pneumatic lifting effect.

[0028] An air pipe 42 is connected between the air compressor 41 and the lifting cylinder 43. A control switch 44 is provided on the lifting cylinder 43. Three buttons are preset on the control switch 44 to control the pneumatic slide bar 5 on the lifting cylinder 43 to slide up and down slowly and achieve real-time positioning effects through the air compressor 41 respectively.

[0029] The identification pointer 22 is a triangular structure as a whole and its tip faces the size scale plate 61. The smooth layer 311 is evenly coated along the inner wall surface of the guiding slide opening 31. The smooth layer 311 is a ceramic coating with a flat and smooth surface and strong high and low temperature stability.

[0030] The front view cross-section of the lower roller frame 21 is a U-shaped structure. The lighting plate 23 is arranged at one end facing the size scale plate 61. LED lamp beads are preset in the lighting plate 23, which is power-saving, durable and has a high light intensity.

[0031] There are two welding plates 3 that are symmetric left and right. The left and right welding plates 3 are slidably connected to the first frame plate 6 and the second frame plate 7 respectively through the guiding slide openings 31. The top view cross-section of the guiding slide openings 31 is a square-shaped opening structure, which plays a guiding role for the vertical sliding of the two welding plates 3.

[0032] Reinforcing rib plates 51 are provided between the pneumatic slide bar 5 and the lower roller frame 21. There are four reinforcing rib plates 51 arranged in a circle. The reinforcing rib plates 51 are made of high-quality hard alloy steel, with high strength and durability without deformation.

[0033] The reinforcing rib plates 51 are trapezoidal structures as a whole. The four reinforcing rib plates 51 greatly improve the structural stability between the pneumatic slide bar 5 and the lower roller frame 21.

[0034] The motor shaft of the coating motor 71 passes through the second frame plate 7 and is fixedly arranged with the preset rotating shaft of the upper coating roller 1. The lower coating roller 2 is rotatably arranged on the lower roller frame 21 through a preset rotating shaft. Since the lower coating roller 2 and the upper coating roller 1 are in an extrusion state through the advertising cloth, the advertising cloth can be driven to convey, and at the same time, the lower coating roller 2 is driven to rotate, so as to realize the uniform coating of the preset waterproof coating liquid on the upper and lower end faces of the advertising cloth by the lower coating roller 2 and the upper coating roller 1 at the same time.

[0035] Working mode: During the entire process of coating, drying, and winding (prior art, already described in the background art), the advertising cloth passes through the upper coating roller 1 and the lower coating roller 2. Then, press the button on the control switch 44, and the air compressor 41 is powered on to give the pneumatic slide rod 5 in the control lifting cylinder 43 slow up and down sliding, driving the lower roller frame 21 and the lower coating roller 2 to move slowly up and down. At the same time, the welding plate 3 slides slowly up and down along the first frame plate 6. At this time, the identification pointer 22 will indicate the size on the size scale plate 61 in real time. When the upper and lower ends of the advertising cloth with the current thickness are effectively pressed by the lower coating roller 2 and the upper coating roller 1, stop the lifting cylinder 43 through the control switch 44, and the indicated size of the current identification pointer 22 on the size scale plate 61 can be recorded to facilitate the direct adjustment of the distance between the lower coating roller 2 and the upper coating roller 1 for the advertising cloth of this batch thickness next time.

[0036] The above operations can achieve the pneumatic up and down adjustment of the lower coating roller 2 for different thicknesses of the advertising cloth to be coated. Combining the size scale plate 61 and the identification pointer 22 ensures the precise adjustment of the distance between the upper coating roller 1 and the lower coating roller 2, and overall improves the pneumatic precise lifting application range of the coating roller device for coating the waterproof coating on the surface of the advertising cloth.

[0037] Moreover, when adjusting the distance between the upper coating roller 1 and the lower coating roller 2, the lighting plate 23 can be powered on and opened. The lighting plate 23 will provide targeted and comprehensive lighting for the identification pointer 22 and the size scale plate 61, ensuring that the operator's eyes can clearly see the size indicated by the identification pointer 22 on the size scale plate 61 during the pneumatic lifting adjustment.

[0038] In addition, by setting a smooth layer 311 structure in the guiding slide opening 31, the smoothness of the lower coating roller 2 sliding up and down along the first frame plate 6 and the second frame plate 7 through the welding plate 3 on the lower roller frame 21 is ensured during the pneumatic lifting adjustment.

[0039] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
