Description

Technical Field

[0001] The invention belongs to the technical field of rubber floor manufacturing, and in particular relates to a manufacturing device and a preparation method for a multi-color grain pattern rubber floor. Background Art

[0002] The rubber floor has bright and vivid colors, and is soft, elastic, non-slip and wear-resistant. It is widely used in hospitals, airports, exhibition halls, subway and high-speed rail carriages, etc. In order to increase the variety of patterns and colors of rubber floor, particles are mixed for embellishment. Conventional particles are generally pure colors, and the color is monotonous and not beautiful enough. In addition, due to the singleness and monotony of the color of the flower spots themselves, the flower spots can only be a simple mixture of one color or two colors for a long time, and it is impossible to achieve a complex color mixing effect, and it is impossible to create the three-dimensional and saturated color effect of the particle flower spots, so as to make the product more diversified and meet the aesthetic requirements.

[0003] The manufacturing process of rubber flooring generally includes three steps: extrusion, calendering and vulcanization. The calendering process uses a heated roller to heat the extruded rubber flooring and press it thin to form the initial shape of the rubber flooring. The vulcanization process uses vulcanization equipment to press and keep the rubber sheet warm for a certain period of time to strengthen the rubber flooring. The particles for aesthetic decoration are added to the extruded rubber sheet before calendering. Since the particles are hard, they cannot be effectively integrated with the rubber sheet during the calendering process. Although the subsequent vulcanization process will further heat and compact it, the bonding effect of the particles and the rubber sheet is still not ideal.

[0004] The vulcanization equipment used in the production of continuous rubber flooring is mostly drum vulcanizers, but drum vulcanizers have the following disadvantages: To improve the vulcanization efficiency, its volume must be increased, resulting in the vulcanization equipment in the workshop being the largest equipment with very high equipment costs, forming a linear relationship between cost, equipment and output value, making it impossible to achieve greater output and greater economic benefits in the same space.

[0005] The present invention designs a multi-color grain pattern rubber floor manufacturing equipment to produce multi-color particles to improve the aesthetics of the rubber floor. The present invention uses a spreading component to evenly spread the multi-color particles on an unhardened rubber floor and uses a vulcanization component with a vortex structure and a small volume to efficiently vulcanize the rubber floor. Summary of the invention

[0006] Based on this goal, it is necessary to provide a multi-color grain-shaped rubber floor manufacturing equipment to address the problems existing in the current rubber floor manufacturing equipment. The present invention uses a twisting and pulling component to pull and twist the multi-color rubber strips extruded from the extruder and still in a softened state in a regular, non-directional and multi-angle manner, so that the multi-color rubber strips are evenly twisted together in a spiral or superimposed and irregular state to form a colored rope-shaped rubber strip while moving downward. The present invention uses a shearing component to shear the colored rope-shaped rubber strips from the upper twisting and pulling component at a certain speed or an adjustable speed and at multiple angles into colored particles with different color requirements. The present invention uses a spreading component to evenly spread the colored particles from the upper shearing component on the rubber floor pulled from the pulling and compacting component to the vulcanizing component. The colored particles that reach the rubber sheet form a preliminary combination with the rubber sheet under the extrusion and heating of the pulling and compacting component, which provides an important process for the perfect combination of the particle points and the rubber floor. The vulcanization assembly in the present invention forms a vortex channel with a long distance that allows the rubber floor to pass through by means of the first vortex guide plate and the second vortex guide plate distributed on the same axis, thereby extending the vulcanization time of the rubber floor and effectively reducing the volume of the vulcanization equipment. The first conveyor belt and the second conveyor belt respectively arranged on the vortex surfaces of the first vortex guide plate and the second vortex guide plate can effectively pull the rubber floor to move in the vortex channel and further heat and compact the rubber sheet passing through, thereby achieving the miniaturization of the vulcanization equipment assembly and the enhanced vulcanization treatment of the rubber floor.

The two pulling wheels 407 twist, entangle and pull the multiple strands of rubber strips 103 downward.

[0053] When the twisted rubber strip 103 reaches between the two shearing knives 509, the pneumatic push rod 510 drives the two telescopic rods 504 to clamp and fix the rubber strip 103 through the rack 502 and the ninth gear 503. As the telescopic rods 504 further shrink, the two shearing knives 509 shear the twisted colored rubber strips 103 into rubber particles. The rubber particles fall into the square barrel 605 that reciprocates horizontally under the drive of the fifth motor 610 through the hopper 612 in the spreading component 600. The rubber particles entering the square barrel 605 are evenly spread on the rubber bottom plate in a single layer along the two sieve plates 606 under the vibration of the vibrator 607 outside the square barrel 605.

[0054] The pulling and compacting assembly 200 heats and thins the rubber floor 102 with the colored rubber particles evenly spread thereon, and conveys the rubber floor 102 with the rubber particles preliminarily compacted and bonded to the entrance of the vortex channel between the first conveyor belt 705 and the second conveyor belt 706 of the vulcanization assembly 700.

[0055] Driven by the sixth motor 716 , the first conveyor belt 705 and the second conveyor belt 706 in the vulcanization assembly 700 synchronously drive the rubber floor 102 entering the vortex channel to move toward the winding assembly 800 and further heat and compact the rubber floor 102 , thereby completing the vulcanization of the rubber floor 102 .

[0056] The vulcanized rubber floor 102 is wound and collected under the drive of the winding roller 803 in the winding assembly 800 .

[0057] The present invention pulls downward and circumferentially twists the multi-color rubber strip 103 extruded from the extruder unit 300 and still in a softened state by twisting the pulling assembly 400, so that the multi-color rubber strip 103 is evenly twisted together in a spiral state to form a colorful rope-shaped rubber strip 103 while moving downward. The present invention shears the colorful rope-shaped rubber strip 103 from the upper twisting pulling assembly 400 into colorful particles by the shearing assembly 500. The present invention evenly spreads the colorful particles from the upper shearing assembly 500 on the rubber floor 102 pulled by the pulling and compacting assembly 200 to the vulcanizing assembly 700 by the spreading assembly 600, and the colorful particles reaching the rubber sheet form a preliminary combination with the rubber sheet under the extrusion and heating of the pulling and compacting assembly 200. The vulcanization assembly 700 of the present invention forms a vortex channel with a long distance that allows the rubber floor 102 to pass through by means of the first vortex guide plate 702 and the second vortex guide plate 703 that are coaxially distributed, thereby extending the vulcanization time of the rubber floor 102 and effectively reducing the volume of the vulcanization equipment. The first conveyor belt 705 and the second conveyor belt 706 respectively arranged on the vortex surfaces of the first vortex guide plate 702 and the second vortex guide plate 703 can effectively pull the rubber floor 102 to move in the vortex channel and further heat and compact the rubber sheet passing through, thereby achieving the small volume of the vulcanization assembly 700 and the enhanced vulcanization treatment of the rubber floor 102.
