Description

Wall paper pasting process for house decoration

Technical Field

The invention belongs to the technical field of decoration construction, and particularly relates to a wall paper pasting process for house decoration.

Background

With the improvement of living standard, people have higher and higher requirements on home decoration. The wallpaper is used as a wall surface decoration material frequently used in home decoration, compared with the same common latex paint, the wallpaper is not polluted in the production process from raw materials to finished products, and the adhesive of most of the wallpaper is very environment-friendly. And the wallpaper is convenient to use, long in service life, erasable and washable, convenient and easy. The wallpaper can be normally used for 10 years, if slight stains are wiped off by using wet rags, serious stains such as oil smoke, color, food residues, pen graffiti and the like can be wiped off by using rags or toothbrushes to dip household cleaning agents. There are several disadvantages in the prior art:

1. most wallpaper pasting work is finished manually, whether the wallpaper is kept horizontal needs to be judged by workers with naked eyes, and the situation of deflection is easy to occur;

2. when the wallpaper is pasted, an operator needs to paste the wallpaper downwards from a high place by means of tools such as an escalator, and workers have the risk of falling injury when working at the high place. When the wallpaper is pasted, workers need to lightly scrape the wallpaper from top to bottom by using a scraper so that the wallpaper is flat and clings to the wall surface, and the construction method completely relying on manpower is low in efficiency and easy to generate bubbles;

3. most of the existing automatic wallpaper pasting devices cannot realize wallpaper pasting at an inner wall corner of 90 degrees;

When the sticker device in S5 is operated, the worker first checks whether the wallpaper remaining on the roller 209 is enough, and then pushes the sticker device to a proper position, where the status of the device is as shown in fig. 1. The staff need with the wall paper front end down put with the coincidence of ground, rely on roller 209 to guarantee that the wall paper is perpendicular, paste the place ahead of push pedal subassembly and lower part wall paper after that, make push pedal subassembly and wall paper laminating with sticker equipment antedisplacement afterwards, starting drive after that. The first motor 213 is started to drive the first lead screw 211 fixed with the main shaft to rotate, and because the first lead screw 211 is rotatably connected to the support frame 2, the first lead screw 211 is in threaded connection with the transverse plate 207, and the transverse plate 207 is in sliding fit with the first chute 210 on the support frame 2, when the first motor 213 is started, the transverse plate 207 and the two connecting rods 208, the second motor 206 and the cross rod 204 fixed thereon move upwards together. And because the roller 209 is hinged on the two connecting rods 208, the left sliding rod 101a on the push plate assembly is in sliding fit with the left sliding frame 214a, the right sliding frame 214b is in sliding fit with the right sliding frame 214b, the left sliding frame 214a and the right sliding frame 214b are respectively hinged on the two first sliding blocks 205, the two first sliding blocks 205 are fixed on the transverse plate 207 through the cross rod 204, the first electric push rod 102 is fixed on the transverse plate 207, the push plate assembly and the roller 209 move upwards together, and the push plate assembly clings to the wallpaper in the process to enable the wallpaper to be tightly attached to the wall surface to prevent bubbles from being generated.

When the push plate assembly and the roller 209 move to a fixed position, the transverse plate 207 touches the first limit switch 216 to control the first motor 213 to stop, the second motor 206 is started, because the two connecting rods 208 are hinged with the transverse plate 207, one of the connecting rods 208 is fixed on the main shaft of the second motor 206, the roller 209 is hinged between the two connecting rods 208, the second motor 206 is started to enable the roller 209 to rotate backwards to an angle shown in figure 8 around the upper part of the supporting frame 2, then the first motor 213 is started to enable the transverse plate 207 to move to a maximum stroke position, then the second electric push rod 215 extends, because the second electric push rod 215 is fixed on the supporting frame 2, the supporting frame 2 moves upwards until the wallpaper is pressed by the upper surface of the push plate assembly to be attached to the wall and the ceiling, the press button 110 is pressed to move and touch the second limit switch 109 (see figures 7 and 8), and then the second limit switch 109 controls the left electromagnet assembly 104, The right electromagnet assembly 104b and the first electromagnet assembly 108 are electrified and extended, so that the left cutter 106, the right cutter 107 and the first cutter 105 are ejected out to cut off wallpaper attached to the corner. Then the operator pushes the sticker device away from the wall surface, presses the reset button to reset the device, and the wallpaper pasting process on the horizontal wall surface is finished once.

When wallpaper is pasted at a corner, the first electric push rod 102 extends for a fixed length, because the left slide bar 101a and the right slide frame 214b are hinged on the connecting block 112, one end of the first electric push rod 102 is fixed with the connecting block 112, the left slide bar 101a and the right slide frame 214b are respectively in sliding fit with the left slide frame 214a and the right slide frame 214b, and the left slide frame 214a and the right slide frame 214b are respectively hinged on the two first sliders 205, the first electric push rod 102 extends to drive the left slide bar 101a and the right slide frame 214b to move, so that the left slide bar 101a and the right slide frame 214b are in a mutually perpendicular state (as shown in fig. 2).
