Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of carpet raw material cleaning, in particular to a raw material cleaning device for carpet production and a method thereof. BACKGROUND

[0002] The raw materials for carpet production are mainly divided into three categories: natural fibers, chemical fibers, and blended fibers. The natural fiber category mainly includes wool. A raw material cleaning device for carpet production is a special equipment for cleaning, removing impurities, and degreasing natural fiber raw materials for carpet production, aiming to remove dust, grease, grass clippings, pigments, and other impurities in the raw materials, and improve the quality of subsequent textile and dyeing processes. For example, existing technology 1, a kind of anti-caking wool cleaning device for livestock industry and its working method (CN110983451A), sets up a movable feeding mechanism, combines the intermittent blowing generated by the tearing and cleaning mechanism, and promotes the caked wool to pass through the feeding hopper into the cleaning tank through the movable baffle and the discharging serrations, thereby effectively solving the problem that the general wool cleaning device cannot produce a large impact force on the wool in water, and the caked wool needs a long time to dissolve in water, which affects the work efficiency to a certain extent. Another existing technology 2, a kind of wool cleaning device for sheep breeding and its use method (CN117248278A), uses a cleaning assembly to realize rubbing and squeezing cleaning, improves the cleaning efficiency, shortens the cleaning time, and controls the water content to reduce the difficulty of the drying step to the greatest extent. The utility model has the advantages of high practicability, and uses a booster fan to filter and stir the cleaning liquid to the greatest extent to improve the mixing of wool and cleaning liquid, and uses a sealing shell to realize the centralized adsorption of wool to ensure the efficiency of rubbing.

[0003] Although the existing technology can realize rubbing and squeezing cleaning, it has the problems of poor rubbing effect and poor grease removal effect when cleaning wool. The single rubbing effect is poor, and the cleaning frequency or soaking time needs to be increased, which doubles the consumption of water resources, detergents, and energy. After the unprocessed wool is made into a carpet, the residual grease and impurities make the carpet surface easy to absorb dust and liquid stains, and the fiber combination is weak, which is easy to ball and hook after abrasion.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of the present application.

[0021] The utility provides the following technical scheme, a raw material cleaning device for carpet production and its method: Embodiment one: in order to solve the problem of poor rubbing effect and poor degreasing effect of the existing cleaning device when washing wool, the utility discloses: a support frame 1, the bottom of the support frame 1 is provided with a water tank 2, two ends of the inside of the support frame 1 are rotatably connected with rotating rods 3, one end of the support frame 1 is provided with an output shaft and a driving motor connected with one of the rotating rods 3, a conveying belt 4 (as shown in Figures 1-3 ) is arranged between the two rotating rods 3, a rubbing plate 5 is arranged in the inside of the support frame 1, rotating seats are arranged at both ends of the inside of the rubbing plate 5, support blocks 6 are rotatably connected in the two rotating seats, rubbing frames 7 are arranged at one end of the two support blocks 6, a row of rollers 8 (as shown in Figures 4-7 ) are arranged at the bottom of each of the two rubbing frames 7, a row of drainage holes 9 are arranged at the inner bottom of each of the two rubbing frames 7, lifting assemblies for lifting the rubbing plate 5 are arranged on the two sides of the support frame 1, water injection assemblies for injecting water into the inside of the rubbing frame 7 are arranged in the inside of the water tank 2, the lifting assembly comprises four sliding grooves arranged around the support frame 1, sliding strips 10 are slidably connected in the four sliding grooves, support strips 11 (as shown in Figures 1-3 ) are arranged between the two sliding strips 10 on the two sides, electric telescopic rods are arranged at both ends of the outside of the support frame 1, the output ends of the electric telescopic rods are connected with the two support strips 11 respectively, rotating columns 12 are arranged at one end of the four sliding strips 10, connecting rods 13 are rotatably connected at the top of the rubbing plate 5 at the other end of the four rotating columns 12, and torsional springs (as shown in Figure 9 ) are arranged between the four rotating columns 12 and the four sliding strips 10 respectively, the water injection assembly comprises eight support plates arranged around the two sides of the support frame 1, hollow cylinders 14 are arranged between the eight support plates, sliding rods 15 connected with the bottom of the four sliding strips 10 are slidably connected in the four hollow cylinders 14 respectively, and pistons 16 (as shown in Figure 3As shown), each of the four hollow cylinders 14 inside the water tank 2 has a limiting plug 17 at one end. Each of the four hollow cylinders 14 has a flexible hose 18 at one end of its upper part. The other ends of the two flexible hoses 18 on both sides pass through the support frame 1 and the kneading plate 5 and are equipped with T-shaped tubes 19. The two T-shaped tubes 19 pass through the two kneading frames 7 respectively. A filter plate is installed in the upper part of the water tank 2. A scraper that fits against the conveyor belt 4 is installed at one end of the top of the water tank 2. A collection frame is also installed at one end of the upper part of the water tank 2. A row of first support rollers is installed inside the support frame 1, and all of the first support rollers are installed inside the conveyor belt 4. Second support rollers are symmetrically arranged at both ends inside the support frame 1, and the two second support rollers are respectively located at both ends of the bottom of the conveyor belt 4 (e.g., ...). Figure 3 (As shown).

[0022] After the drive motor starts, its output shaft drives the rotating roller 3 to rotate, thereby driving the conveyor belt 4 to run. Wool is then placed on the conveyor belt 4, and supported by a row of first and second support rollers, the conveyor belt 4 smoothly transports the wool to the cleaning area inside the support frame 1. At this time, the electric telescopic rod is activated, causing it to push the support bar 11 to move. The support bar 11 drives the sliding strips 10 on both sides to slide in the chute (e.g., ...). Figure 1 As shown), the movement of the slider 10 is transmitted to the rubbing plate 5 through the rotating column 12 and the connecting rod 13, thereby causing the rubbing plate 5 and the rubbing frame 7 to approach and squeeze the wool. When the rubbing frame 7 contacts the wool, as the slider 10 continues to descend, it will also cause the connecting rod 13 and the rubbing plate 5 to move forward, thereby causing the rotating column 12 to rotate the torsion spring (as shown). Figure 9 As shown), when the slider 10 moves up and down, the slider 15 slides inside the hollow cylinder 14. The piston 16 at the bottom of the slider 15 moves inside the hollow cylinder 14, thereby drawing the cleaning agent from inside the water tank 2 into the hollow cylinder 14. When the slider 10 moves down, the piston 16 pushes down, compressing the cleaning agent inside the hollow cylinder 14. The cleaning agent is forced into the hose 18, which delivers the cleaning agent to the T-tube 19. The T-tube 19 injects the cleaning agent into the rubbing frame 7. When the rubbing frame 7 approaches the wool, the cleaning agent is evenly sprayed onto the wool through the drain hole 9 (as shown). Figure 5 and Figure 7 As shown in the figure, physical cleaning is achieved by combining the roller 8.

[0023] Example 2: Unlike Example 1, a rotating assembly can be used to drive the roller 8 to oscillate on the wool surface. It is disclosed that: a rotating assembly is provided at the top of the support frame 1 to drive the kneading frame 7 to rotate. The rotating assembly includes two rotating shafts 20 respectively disposed inside the two support blocks 6. Figures 2-5 and Figure 8As shown), the two rotating shafts 20 are rotatably connected to the two rotating seats and the kneading board 5 respectively. The outer surfaces of the two rotating shafts 20 are movably connected to fixed sleeves 21 located at both ends of the top of the support frame 1. Each fixed sleeve 21 has a limiting groove 22 around its perimeter. Each of the upper parts of the two rotating shafts 20 has a limiting block 23 slidably connected to the limiting groove 22 (as shown). Figure 8 (As shown).

[0024] As the kneading board 5 descends, it also drives the rotating shaft 20 to move inside the fixed sleeve 21, while the limiting block 23 on the rotating shaft 20 moves inside the limiting groove 22 (e.g., Figure 8 As shown), then, guided by the limiting groove 22, when the rotating shaft 20 descends, it will rotate while descending, thereby causing the support block 6 and the kneading frame 7 to swing (as shown). Figure 5 As shown in the figure, this causes the roller 8 to swing on the wool surface, thus rubbing the wool.

[0025] Example 3: Unlike Example 2, a cleaning component can be used to clean the drain hole 9. The invention discloses that: a cleaning component for cleaning the drain hole 9 is provided inside the kneading frame 7. The cleaning component includes two rows of sliding posts 24 slidably connected inside the two kneading frames 7, and each row of sliding posts 24 has a cleaning post 25 at its bottom (e.g., ...). Figure 7 As shown), tension springs are provided between the tops of the two rows of cleaning columns 25 and the tops of the two kneading frames 7, respectively. Two rows of wedge-shaped blocks 26 are provided on both sides inside the kneading plate 5 (as shown). Figure 6 As shown), the two rows of wedge blocks 26 and the two rows of sliding columns 24 are equidistantly distributed, the two rows of cleaning columns 25 and the two rows of drainage holes 9 are on the same horizontal line, and the shapes and specifications of the cleaning columns 25 and the drainage holes 9 are compatible.

[0026] When the kneading frame 7 swings, it will cause the sliding column 24 to gradually come into contact with the wedge block 26, and then under the action of the inclined surface of the wedge block 26 (such as... Figure 6 As shown), this causes the sliding column 24 to descend, pulling the tension spring. The cleaning column 25 then reaches the drain hole 9 and slides inside to clean it, preventing blockages. When the kneading frame 7 moves the sliding column 24 away from the wedge block 26, the cleaning column 25 will be under the action of the tension spring (as shown). Figure 7 (As shown), reset it so that drain hole 9 can drain normally.

[0027] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0028] The content not described in the specification is the prior art known to the person skilled in the art, although the present application is described in detail with reference to the foregoing embodiments, the skilled person in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
