Description

Technical Field

[0001] The present invention relates to a device for producing floor leather, in particular to a device for producing floor leather containing a stabilizing layer and capable of forming a three-dimensional structure. Background Art

[0002] Floor coverings are a common interior floor covering material in buses. Because floor coverings are inherently flat, bus manufacturers must cut, flanging, and weld them to accommodate raised steps and access hatches within the bus. This approach presents two drawbacks:

[0003] 1. The structure of the floor covering does not fit in with the local structure inside the bus. The edge of the floor covering does not have a flange structure or the flange does not completely cover the load-bearing floor. The penetrating water will also cause the floor covering to come unglued and the load-bearing floor to accumulate water and become smelly.

[0004] 2. The structural stability is poor. The floor leather is prone to cracking and deformation during use. When water enters under the floor leather, it will cause the floor leather to come unglued and the supporting floor to accumulate water and become smelly.

[0005] There are two solutions to the above two defects on the market:

[0006] 1. During the production process of floor coverings, a seamless water retaining edge is formed by adding a three-dimensional structure, which can effectively prevent water seepage. However, the remaining flat parts still have the problem of poor structural stability.

[0007] 2. Adding fiberglass felt inside the floor leather as a stabilizing layer improves the structural stability of the floor leather, making it resistant to trampling, wear-resistant, and not easy to wrinkle, making the floor leather not easy to crack and deform. However, the disadvantage of this type of floor leather is that it cannot form a three-dimensional structure through subsequent processing, and the edge cannot solve the problem of water seepage. Even if additional cutting, folding, welding and other processing are performed, since the connection between the floor leathers requires the use of floor leather welding rods, and the performance of the floor leather welding rods themselves is different from that of the floor leather, the welds will show problems such as wear, tear, deformation and cracking due to alternating hot and cold, and cracking due to trampling and vibration before the floor leather.

[0008] Existing floor covering production equipment can only produce floor coverings with a single structure and cannot take into account both of the above solutions. Summary of the Invention

[0009] The purpose of the present invention is to overcome the existing defects and provide a device for producing floor leather containing a stabilizing layer and capable of forming a three-dimensional structure, thereby solving the problem that current floor leather production equipment can only produce floor leather with a single structure.

[0010] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0011] A device for producing floor leather containing a stabilizing layer and capable of forming a three-dimensional structure comprises an unwinding device, a first coating device, a first oven, a second coating device, a second oven, a third coating device, a third oven, an embossing device, a cooling device and a winding device, which are arranged in sequence. An online cutting device is provided between the second coating device and the second oven to cut the stabilizing layer material. The cutting is based on removing the stabilizing layer material corresponding to the floor leather portion to be subsequently three-dimensionally formed, and retaining the stabilizing layer material corresponding to the remaining portion. The obtained stabilizing layer material is pressed and adhered to a semi-finished product coated with a secondary slurry and then placed in a second oven for baking and plasticization.

[0012] Furthermore, the online cutting device includes a base frame, a cutting platform is provided on the base frame, a stabilizing layer material unwinding device is provided at the feeding end of the cutting platform, flattening rollers are provided at both ends of the upper end surface of the cutting platform, and a discharging roller is provided at the discharging end of the cutting platform; the online cutting device is equipped with a programmable vibration cutting machine or a programmable laser cutting machine, and the cutting head of the programmable vibration cutting machine or the programmable laser cutting machine is located above the cutting platform.

[0013] Furthermore, a wire storage lifting roller and a tensioning lifting roller are sequentially arranged between the flattening roller and the discharge roller at the discharge end of the cutting platform.

[0014] Furthermore, an automatic waste discharge device is provided below the space at the discharge end of the cutting platform. The automatic waste discharge device includes a plurality of transmission rollers, and a waste conveyor belt is arranged around the transmission rollers. The conveying direction of the waste conveyor belt is horizontally perpendicular to the discharge direction of the online cutting device.

[0015] Furthermore, a powder spreading device is provided between the third coating device and the third oven.

[0016] Furthermore, the powder sprinkling device includes a bracket, the upper end of the bracket is located above the floor leather conveyor line, and a plurality of programmable control powder sprinkling devices arranged in parallel and spaced apart are provided on the upper end of the bracket. Each of the programmable control powder sprinkling devices includes a plurality of sand feeding gears, and the sand feeding gears are arranged in a line. A hopper is provided above each of the sand feeding gears, and an electric control valve is provided at the lower end of the hopper. A driving worm is engaged with the side of each of the sand feeding gears.

[0017] Furthermore, a flattening and shaping device is provided between the first oven and the second coating device, and between the second oven and the third coating device.

[0018] The present invention provides an apparatus for producing floor leather containing a stabilizing layer and capable of forming a three-dimensional structure. During the process of adding the stabilizing layer, the stabilizing layer material at the position where three-dimensional forming is required is removed. The floor leather thus produced has the conditions for subsequent three-dimensional forming steps, so that the final floor leather can simultaneously eliminate two defects of existing floor leathers.

[0026] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] like Figure 1-6 As shown, an apparatus for producing floor leather containing a stabilizing layer and capable of forming a three-dimensional structure comprises an unwinding device 1, a first coating device 2, a first oven 3, a second coating device 4, a second oven 5, a third coating device 6, a third oven 7, an embossing device 8, a cooling device 9 and a winding device 10, which are arranged in sequence. An online cutting device 11 is provided between the second coating device 4 and the second oven 5 to cut the stabilizing layer material. The cutting is based on removing the stabilizing layer material corresponding to the floor leather portion to be subsequently three-dimensionally formed, and retaining the stabilizing layer material corresponding to the remaining portion. The obtained stabilizing layer material is pressed and adhered to the semi-finished product coated with a secondary slurry and then enters the second oven for baking and plasticization.

[0028] Working principle:

[0029] A non-woven fabric is selected as the backing material, and a glass fiber mat is selected as the stabilizing layer material. The unwinding device lays the non-woven fabric backing flat and stretches it to be sent to the first coating device. The first coating device applies PVC slurry to the surface of the non-woven fabric backing, and the first oven bakes and plasticizes it to obtain a first-stage semi-finished product. The second coating device applies PVC slurry to the surface of the first-stage semi-finished product. The online cutting device cuts the glass fiber mat according to the set program and presses and adheres the cut glass fiber mat to the first-stage semi-finished product coated with PVC slurry. The second oven bakes and plasticizes it to obtain a second-stage semi-finished product. The third coating device applies PVC slurry to the surface of the second-stage semi-finished product, and the third oven bakes and plasticizes it to obtain a third-stage semi-finished product. The embossing device uses a steel roller with concave and convex patterns to emboss decorative patterns on the third-stage semi-finished product. The cooling device is equipped with several steel rollers. The third-stage semi-finished product with the embossed decorative pattern passes between the steel rollers, and the steel rollers take away the heat to obtain the finished floor leather with a stabilizing layer. Finally, the winding device rolls up and stores it. The finished floor leather product containing the stabilizing layer obtained above has a good structural stability in the portion containing the stabilizing layer, and the portion without the stabilizing layer is subjected to subsequent three-dimensional forming processing (such as vacuum forming, hot pressing, etc., to make various convex and concave shapes) to obtain a three-dimensional structure. The final product has the advantages of both wear resistance and water seepage prevention.

[0030] The online cutting device 11 includes a base frame 111, on which is mounted a cutting platform 112. A glass mat unwinding device 113 is located at the infeed end of the cutting platform 112. Flattening rollers 114 are located at each end of the upper surface of the cutting platform 112, and a discharge roller 115 is located at the discharge end of the cutting platform 112. The online cutting device 111 is equipped with a programmable vibration cutter or a programmable laser cutter, with a cutting head 116 located above the cutting platform 112. The flattening rollers ensure the flatness of the glass mat on the cutting platform, and the cutting head cuts the glass mat according to a pre-set program.

[0031] A storage roller 117 and a tensioning roller 118 are sequentially positioned between the flattening roller 114 and the discharge roller 115 at the discharge end of the cutting platform 112. By controlling the rise and fall of the storage roller, the travel of the fiberglass mat can be changed, thereby adjusting the feeding rhythm of the fiberglass mat and controlling the time point and attachment position of the fiberglass mat and the semi-finished product coated with the secondary slurry. By controlling the rise and fall of the tensioning roller, the fiberglass mat is kept in a properly stretched state.

[0032] An automatic waste discharge device 12 is located below the discharge end of the cutting platform 112. This device comprises four drive rollers 121, each surrounded by a waste conveyor belt 122. The conveyor belt 122 is oriented horizontally and perpendicularly to the discharge direction of the inline cutting device 11. The waste conveyor belt carries the cut fiberglass mat that falls from above to a waste bin located outside the equipment.

[0033] A powder spreading device 13 is provided between the third coating device 6 and the third oven 7. The powder spreading device is used to spread quartz sand on the surface slurry of the floor leather and press and stick it and bake it for plasticization, thereby making the surface of the floor leather more wear-resistant.

[0034] The powder spreading device 13 includes a bracket 131, the upper end of which is positioned above the floor covering conveyor line. Three programmable powder spreading devices are arranged in parallel and spaced apart. Each programmable powder spreading device includes thirty-one sand feeding gears 132 arranged in a line. A hopper 133 is located above each sand feeding gear 132, and an electrically controlled valve is installed at the lower end of the hopper 133. A drive worm 134 engages the side of each sand feeding gear 132. The electrically controlled valve and drive worm are activated and deactivated according to a pre-set program, so that the quartz sand in the tooth grooves is sprinkled onto the surface slurry of the floor covering according to the program, arranging the quartz sand in an orderly manner into a predetermined pattern, thereby increasing wear resistance and providing a decorative effect.

[0035] A flattening and shaping device 14 is provided between the first oven 3 and the second coating device 4 and between the second oven 5 and the third coating device 6 to ensure the flatness of the surface of the semi-finished product of the PVC slurry during the second and third coating, thereby ensuring the coating effect.

[0036] The present invention provides an apparatus for producing floor leather containing a stabilizing layer and capable of forming a three-dimensional structure. During the process of adding the stabilizing layer, the stabilizing layer material at the position where three-dimensional forming is required is removed. The floor leather thus produced has the conditions for subsequent three-dimensional forming steps, so that the final floor leather can simultaneously eliminate two defects of existing floor leathers.

[0037] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
