Description

Technical Field

[0001] The present invention relates to the technical field of wall sticker production, in particular to an environmentally friendly composite wall sticker and a production process. Background Art

[0002] Wall stickers, also known as instant stickers or "sticky notes," are pre-designed, ready-made, self-adhesive stickers that require only manual application. They can be applied to walls, glass, tiles, countertops, and other surfaces, creating a stunning decorative effect. They're easy to apply, allowing you to easily change the atmosphere of a space with a simple, localized application without significantly damaging the wall.

[0003] After the wall stickers are produced, they are rolled up on the surface of a round roller. They need to be cut into pieces of the same specifications before they can be packaged. Most of the daily slicing is done by manually placing the wall stickers on a workbench and then pushing them flat with a pressing plate, which makes the glued side of the wall stickers more uniform. When pushing them flat, glue may overflow at the edges of the wall stickers. If not cleaned in time, it may remain on the surface of the wall stickers. Summary of the Invention

DETAILED DESCRIPTION

[0032] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] The present invention will be further described below with reference to the embodiments.

[0034] Example 1: An environmentally friendly composite wall sticker and its production process, comprising a wall sticker body, wherein the bottom surface of the wall sticker is provided with a waterproof layer, the bottom surface of the waterproof layer is provided with a flame retardant layer, the bottom surface of the flame retardant layer is provided with a fireproof layer, and the bottom surface of the fireproof layer is provided with a sound insulation layer.

[0035] Environmentally friendly composite wall stickers and production process, including the following steps:

[0036] S1. Environmentally friendly composite wall stickers are made by mixing PE particles and foaming agent and foaming them in a foaming machine to form foam. The foam is then pressed into a wall sticker. The pressed wall sticker is rolled on the surface of a round roller and glued to the bonding surface of the wall sticker by a gluing machine.

[0037] S2. After gluing, the wall sticker roll is passed through a trimming machine to cut off the irregular edges on both sides of the wall sticker;

[0038] S3. After trimming, the wall sticker roll is cut into multiple wall stickers of the same specifications by a slicer. When slicing, glue will overflow at the edge of the wall sticker, which needs to be scraped off.

[0039] Example 2: A slicing device includes a workbench 1. A wall is attached to the surface of the workbench 1 for conveying and cutting operations. An L-shaped bracket 2 is fixedly installed on one side of the top of the workbench 1. Hydraulic rods are symmetrically fixedly installed at the bottom ends of the L-shaped bracket 2. Pressing plates 3 are fixedly installed at the bottom ends of the two hydraulic rods. The hydraulic rods enable the pressing plates 3 to move up and down. The bottom ends of the pressing plates 3 are provided with a flattening mechanism.

[0040] Reference Figure 1 and Figure 2 The flattening mechanism is used to flatten the wall stickers under the pressing plate 3. Glue scraping mechanisms are provided on opposite sides of the pressing plate 3 to scrape off the overflow glue generated at the edge of the wall stickers when they are flattened.

[0041] Reference Figure 2 and Figure 6The flattening mechanism includes a first slide groove 4 opened at the center position of the pressure plate 3, and a second slide groove 5 is opened at the bottom end of the first slide groove 4. The opposite sides of the first slide groove 4 are slidably connected with tooth plates 6, and the center position inside the first slide groove 4 is rotatably connected with a linkage gear 7. The linkage gear 7 rotates clockwise or counterclockwise under the drive of the servo motor. During the rotation, a force is generated with the two tooth plates 6 so that the two tooth plates 6 slide in different directions along the second slide groove 5 with a triangular push plate 10 through a slider 8. The interior of the second slide groove 5 is symmetrically slidably connected with a slider 8, and a triangular push plate 10 is fixedly installed at the bottom end of the slider 8. A first receiving groove 11 is opened inside the triangular push plate 10, and a plurality of first through holes 12 are opened on the oblique side of the triangular push plate 10. The glue on the oblique side of the triangular push plate 10 is sucked into the interior of the first receiving groove 11 through the first through holes 12.

[0042] Reference Figure 2 and Figure 7 802, the gas gathered in the second through groove 801 quickly enters the air bag 901 through the ventilation groove 802 and the air inlet pipe 9, so that the air bag 901 can be expanded quickly. The second vent hole 806 and the bottom end of one side of the slider 8 are provided with an adjusting groove 804, and an air bag 901 is fixedly installed inside the adjusting groove 804. One side of the air bag 901 is fixedly installed with an air intake pipe 9 extending to the inside of the vent groove 802, and the inside of the adjusting groove 804 is elastically connected with a slide plate 902. The rapidly expanding air bag 901 causes the slide plate 902 to slide quickly inside the first receiving groove 11 with the third piston rod 14 and the second movable plate 15, thereby generating suction. A third through groove 13 is provided on one side of the bottom end of the adjusting groove 804, and the third piston rod 14 is slidably connected inside the third through groove 13. One end of the third piston rod 14 is fixedly connected to the slide plate 902, and the bottom end of the third piston rod 14 is fixedly installed with the second movable plate 15. The opposite inner walls inside the second slide groove 5 are fixedly installed with second slide rods 39, and the surface of the second slide rod 39 is fixedly installed with a second push rod 40 that is adapted to the embedded groove 803.

[0043] Reference Figure 1 and Figure 3The scraping mechanism includes an expansion plate 16 arranged at the corner of the pressure plate 3, and a threaded rod 19 is rotatably connected between two adjacent expansion plates 16. The threaded rod 19 rotates clockwise or counterclockwise under the drive of the servo motor. The surface of the threaded rod 19 is threadedly connected to a threaded slider, and a connecting block 21 is fixedly installed on one side of the threaded slider. The rotating threaded rod 19 interacts with the threaded slider, so that the threaded slider slides back and forth with the trapezoidal shovel block 20 through the connecting block 21. The bottom end of the connecting block 21 is fixedly installed with a trapezoidal shovel block 20, and a second receiving groove is opened inside the trapezoidal shovel block 20. The inclined surface of the trapezoidal shovel block 20 is opened with a second through hole 38 extending to the second receiving groove. The glue on the inclined surface of the trapezoidal shovel block 20 is sucked into the interior of the second receiving groove through the second through hole 38.

[0044] Reference Figure 3 The surface of the connecting block 21 is symmetrically provided with a first through groove 22 extending to the second receiving groove. The first through groove 22 is slidably connected to the first piston rod 23. When the first piston rod 23 slides quickly inside the first through groove 22, suction will be generated. A first piston cylinder 24 is fixedly installed on the opposite sides of the connecting block 21. The second piston rod 25 is elastically connected to the inside of the first piston cylinder 24. The second piston rod 25 is pushed up inside the first piston cylinder 24 under the action of air pressure. The first piston rod 23 is pushed up synchronously through the connecting plate. A connecting plate is fixedly connected between the first piston rod 23 and the second piston rod 25. The bottom end of the first piston cylinder 24 is fixedly connected to the second piston cylinder 26. An L-shaped fixing plate 17 is fixedly installed on one side of the expansion plate 16. The first sliding rod 18 is fixedly installed on the side of the L-shaped fixing plate 17 facing the second piston cylinder 26. When the first sliding rod 18 slides inside the second piston cylinder 26, gas is generated, thereby pushing the second piston rod 25 to quickly push up inside the first piston cylinder 24.

[0045] Reference Figure 3When the first slide rod 18 initially slides inside the second piston cylinder 26, the flow control plate 28 is in a closed state. The gas generated by the sliding of the first slide rod 18 inside the second piston cylinder 26 gathers inside the second piston cylinder 26. A connecting frame 27 is fixedly installed at the connection between the first piston cylinder 24 and the second piston cylinder 26. The flow control plate 28 is elastically connected inside the connecting frame 27. A first vent 29 is opened on the surface of the flow control plate 28. An adjustment frame 30 is fixedly installed on one side of the flow control plate 28. A triangular groove 32 is opened on one side of the adjustment frame 30. A first push rod 31 is fixedly installed on the surface of the first slide rod 18. After the first slide rod 18 moves a certain distance, the first push rod 31 on the surface and the triangular groove 32 on one side of the adjustment frame 30 contact each other, thereby generating thrust. The adjustment frame 30, with the flow control plate 28, slides inside the connecting frame 27 until the first vent 29 is aligned with the air inlet of the first piston cylinder 24. The gas inside the second piston cylinder 26 quickly enters the interior of the first piston cylinder 24, quickly pushing up the second piston rod 25.

[0046] Reference Figure 1 and Figure 4 A mounting frame is fixedly installed on one side of the L-shaped bracket 2, and several tooth blocks 34 are fixedly installed on one side of the mounting frame. A mobile frame 35 is slidably connected to the surface of the mobile frame 35. One side of the mobile frame 35 is rotatably connected to a driving gear 36. The driving gear 36 rotates clockwise or counterclockwise under the drive of the servo motor. The rotating driving gear 36 and the tooth block 34 generate a force to drive the cutting knife 37 to move back and forth intermittently to cut the wall stickers. The cutting knife 37 is fixedly installed on the other side of the mobile frame 35.
