Description

Technical Field

[0001] This utility model belongs to the field of flooring manufacturing technology, and in particular relates to a flooring forming device. Background Technology

[0002] Vinyl flooring, a widely used plastic product in the building decoration field, is favored by the market for its wear resistance, water resistance, and easy cleaning. Traditional vinyl flooring production methods mostly employ extrusion molding, but existing molding equipment has many shortcomings. For example, existing molding rollers are mostly made of steel, which is hard and lacks elasticity. When processing thinner pieces of vinyl flooring, it is prone to indentations or uneven deformation, seriously affecting the product's appearance and quality. Furthermore, when the axial positions of the two molding rollers are slightly misaligned, due to the rigidity of the steel rollers, they are highly likely to collide, leading to equipment damage, production interruptions, and even affecting production efficiency and equipment lifespan. These problems not only increase production costs but also limit the development of vinyl flooring products towards thinner and higher quality. Therefore, developing a vinyl flooring molding device that can flexibly adjust molding parameters, improve production efficiency, and optimize product quality is of significant practical importance. Utility Model Content

[0004] In order to overcome the above shortcomings, the purpose of this utility model is to provide a floor covering forming device to solve the above technical problems.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the technical solution provided in this application is as follows:

[0007] A floor covering forming apparatus includes a forming roller frame, which is mounted on the ground and can move back and forth. The forming roller frame has two opposing first and second movable forming rollers. Between the first and second movable forming rollers, a first and a second fixed forming roller are arranged sequentially from front to back. A third fixed roller is located at the rear end of the second movable forming roller. An extrusion port of a first extruder is located between the first fixed forming roller and the first movable forming roller. An extrusion port of a second extruder is located between the second fixed forming roller and the second movable forming roller. The first and second extruders are vertically arranged in an L-shape. At least one of the first movable forming roller, the second movable forming roller, the first fixed forming roller, the second fixed forming roller, and the third fixed forming roller is an elastic forming roller.

[0008] Preferably, the first moving forming roller, the first fixed forming roller, the second fixed forming roller, the second moving forming roller, and the third fixed forming roller are alternately configured as elastic forming rollers.

[0009] Preferably, the material of the elastic molding roller is silicone.

[0010] Preferably, the upper end of the forming roller frame is provided with a first coating component and a second coating component. The coating material of the first coating component is placed at the rear end of the extrusion port of the first extruder by a guide component provided on the first fixed roller. The coating material of the second coating component is placed at the rear end of the extrusion port of the second extruder by a guide component provided on the second moving forming roller.

[0011] Preferably, the first and second movable forming rollers include forming rollers slidably disposed on the forming roller frame, the forming rollers being connected to a movable lead screw, the movable lead screw being rotatably disposed on a lead screw seat, the lead screw seat being mounted on the forming roller frame, and the movable lead screw rotating under the action of a lead screw motor.

[0012] Preferably, the bottom of the forming roller frame is provided with a rotating wheel, which is slidably mounted on the frame track under the action of a rotating motor.

[0013] Preferably, the rear end of the forming roller frame is connected to a cooling bracket, the cooling bracket is equipped with a cooling fan, and the end of the cooling bracket is connected to a traction component.

[0014] Beneficial effects:

[0015] 1. This invention effectively solves the problem that existing forming rollers cannot adapt to the processing of thin floor coverings by setting multiple movable forming rollers on the forming roller frame and using elastic forming rollers instead of traditional steel rollers. The elastic forming rollers not only avoid the risk of collisions caused by axial offset, but also flexibly adjust the forming pressure according to different product thicknesses and material requirements, significantly improving the production flexibility and adaptability of the device.

[0016] 2. The use of elastic forming rollers also reduces the gap between the two rollers, allowing the floor covering to be pressed more tightly during the forming process. This not only enhances the density of the floor covering but also helps to flatten and roll out the laminating material during the coating process, ensuring a tight bond between the laminating material and the floor covering, further improving the product's appearance and performance.

[0017] 3. The forming roller frame of this device adopts a sliding design and is equipped with rotating wheels and a lead screw motor, enabling rapid and precise roller position adjustment. Meanwhile, the cooling bracket and cooling fan further optimize the cooling and shaping process of the flooring, shortening the forming cycle and significantly improving production efficiency. Furthermore, the cushioning effect of the elastic forming rollers reduces the risk of equipment damage due to collisions, enhancing the stability and service life of the equipment.

[0020] Figure 3 This is a top view according to one embodiment of the present invention. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with specific embodiments and the appendix, provides further details. Figure 1-3 The present invention will be described in further detail below. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the present invention.

[0022] This utility model provides a floor covering forming device including a forming roller frame 9, which is mounted on the ground and can move back and forth. The forming roller frame 9 has two opposing first moving forming rollers 11 and second moving forming rollers 15. Between them, from front to back, are a first fixed forming roller 12 and a second fixed forming roller 13. A third fixed roller 16 is located at the rear end of the second moving forming roller 15. An extrusion port 2 of a first extruder 1 is located between the first fixed forming roller 12 and the first moving forming roller 11, and an extrusion port 4 of a second extruder is located between the second fixed forming roller 13 and the second moving forming roller 15. The first extruder 1 and the second extruder 21 are vertically arranged in an L-shape, allowing the two extruders to be spatially independent and non-interfering. This layout avoids the problems of equipment congestion and operational inconvenience that may occur when arranged side-by-side in traditional methods. Through this vertical layout, the extrusion ports of the two extruders correspond to different forming roller areas, enabling a more rational allocation of production tasks and improving the overall utilization rate of the equipment. Since the two extruders extrude material from different directions, this layout allows for multi-layer co-extrusion production processes. For example, the first extruder 1 can extrude the base material of the floor covering, while the second extruder 21 can extrude the surface decorative layer or functional layer material. Through the L-shaped layout, the two materials can be rapidly compounded between the forming rollers, thereby improving production efficiency and shortening the forming cycle.

[0023] Among them, the first moving forming roller 11, the second moving forming roller 15, the first fixed forming roller 122, the second fixed forming roller 13 and the third fixed forming roller 16 are alternately set as elastic forming rollers, which can save equipment costs. Alternatively, all of them can be elastic forming rollers, which will result in better forming effect.

[0024] The elastic molding roller is made of silicone.

[0025] During operation, the first extruder 1 and the second extruder 21 respectively extrude plastic melts of different colors or materials from the extrusion nozzles. These melts are then compressed by the forming rollers to form the floor covering. The silicone material of the elastic forming rollers has good flexibility and wear resistance, preventing product defects caused by uneven pressure and reducing the risk of collisions between rollers, thus extending the equipment's lifespan. Furthermore, the elastic forming rollers can reduce the gap between rollers, allowing the floor covering to be pressed more tightly, effectively spreading and rolling out the coating material to ensure a close bond between the coating and the floor covering.

[0026] The upper end of the forming roller frame 9 is provided with a first coating assembly 3 and a second coating assembly 5. The coating material of the first coating assembly 3 is positioned at the rear end of the extrusion port of the first extruder 1, between the first moving forming roller 11 and the first fixed forming roller 12, via a guide assembly 14 provided on the first fixed roller 12. The coating material of the second coating assembly is positioned at the rear end of the extrusion port of the second extruder 21 via a guide assembly 14 provided on the second moving forming roller 15. The coating assemblies can effectively protect the surface of the floor covering, preventing scratches and stains, while giving the floor covering better wear resistance and decorative properties. The guide assembly ensures the flatness and stability of the coating material, avoiding wrinkles or displacement during the coating process.

[0027] The first moving forming roller 11 and the second moving forming roller 15 include forming rollers slidably disposed on the forming roller frame 9. The forming rollers are rotatably connected to the moving lead screw 20, which is rotatably disposed on the lead screw seat 19. The lead screw seat 19 is mounted on the forming roller frame 9, and the moving lead screw 20 rotates under the action of the lead screw motor 10. During the production process, according to the thickness and width requirements of the flooring, the position of the forming rollers is adjusted by controlling the rotation of the lead screw motor to achieve the best forming effect.

[0028] The design of the movable forming roller allows for flexible adjustment of the roller spacing to adapt to the production needs of different specifications of flooring veneer, improving the equipment's versatility and production efficiency. Precise roller position adjustment is achieved by controlling the rotation of the moving lead screw via a motor, making operation simple and highly automated.

[0029] The bottom of the forming roller frame 9 is equipped with rotating wheels 18, which slide on the frame track 17 under the action of a rotating motor. During production, the position of the forming roller frame 9 can be adjusted as needed. By controlling the operation of the rotating motor, the forming roller frame 9 can move back and forth along the track, achieving a flexible layout of the overall equipment. The moving function of the forming roller frame 9 allows the equipment to be flexibly adjusted according to the layout of the production line, improving the adaptability and flexibility of the equipment. Motor-driven movement achieves smooth and precise movement, reducing errors and labor intensity caused by manual operation.

[0030] The rear end of the forming roller frame 9 is connected to the cooling bracket 7, on which rotating rollers are evenly arranged. The cooling bracket 7 is equipped with a cooling fan 6, and its end is connected to the traction component 8. After the flooring is formed, the cooling fan 6 on the cooling bracket 7 rapidly cools and shapes the formed flooring. The cooled flooring is then pulled by the traction component 8 to the subsequent cutting and packaging processes. The cooling fan 6 can quickly reduce the temperature of the flooring, shorten the cooling time, and improve production efficiency. The traction component 8 ensures that the flooring can smoothly and continuously enter the subsequent processes after cooling, avoiding product deformation or damage due to uneven cooling.

[0031] In operation, the first and second extruders are started, extruding different colored or functional plastic melts from their respective nozzles. Due to the L-shaped vertical arrangement of the extruders, the two melts can precisely enter the forming areas between the first fixed forming roller and the first moving forming roller, as well as between the second fixed forming roller and the second moving forming roller. In these areas, at least one forming roller is a silicone elastic forming roller, ensuring a smooth and defect-free floor covering surface during the forming process, while reducing the risk of collisions between rollers. Subsequently, the coating material is guided to the rear end of the extruder nozzle by the first and second coating components, entering the space between the forming rollers simultaneously with the formed floor covering, achieving synchronous coating. The coating material is flattened and rolled out by the elastic forming rollers, bonding tightly to the floor covering. The formed floor covering is then rapidly cooled and shaped by a cooling fan on a cooling rack, and subsequently pulled by a traction component to the subsequent cutting and packaging processes. The entire operation process utilizes a motor-driven moving screw and rotating wheels to achieve precise adjustment of the forming rollers and frame, ensuring flexibility and efficiency in the production process, ultimately producing high-quality floor covering products.

[0032] The floor covering forming apparatus of the present invention has significant comprehensive benefits. By employing an L-shaped extruder layout, not only is factory space effectively saved, but equipment layout is also optimized, improving production efficiency and product quality. The use of elastic forming rollers, especially those made of silicone, further enhances the flexibility and adaptability of the equipment, while reducing the risk of equipment collisions and extending its service life. The rational arrangement of the coating assembly ensures the smooth laying of the coating material, further improving the appearance quality and wear resistance of the product. Furthermore, the flexible movement function of the forming rollers and frame allows the equipment to be quickly adjusted according to the needs of the production line, improving the equipment's versatility and production flexibility. The cooperation between the cooling bracket and the traction components ensures that the formed floor covering can be quickly cooled and smoothly transferred to subsequent processes, further optimizing the production flow. Overall, the apparatus of the present invention performs excellently in improving production efficiency, optimizing product quality, reducing production costs, and enhancing equipment stability, providing a strong guarantee for the efficient and high-quality production of floor coverings.
