Description

Technical Field

[0001] The present invention relates to the technical field of carpet production, in particular to a transfer vehicle for carpet production. Background Art

[0002] Carpet is a textile covering used for floor coverings, providing comfort, warmth, and decoration. It's typically made from fiber materials such as wool, nylon, and polyester. It can be used in various places, including homes, offices, and hotels, offering soundproofing, anti-slip properties, and aesthetic appeal. The carpet production process is complex and typically involves the following key steps: design, which involves developing the pattern, color, and style based on market demand and customer requirements. Raw materials are then selected. Common carpet materials include wool, chemical fibers, and silk, each with varying properties and textures. Next, spinning is the process of transforming the selected raw materials into yarn suitable for weaving. Weaving is a key step in carpet production, with common weaving methods being hand weaving and machine weaving. Hand-woven carpets offer exquisite craftsmanship and intricate patterns, but the yield is relatively low. Machine weaving is more efficient and allows for large-scale production. During the weaving process, the yarns are interwoven into the carpet's basic shape and pattern according to the design requirements. Trimming and finishing follow: the woven carpet is trimmed to smooth the surface, remove excess threads and burrs, and undergoes final finishing, including quality inspection and defect repair. There are also many methods for dyeing carpets. One is immersion dyeing, which is to put the woven carpet or yarn into the dye vat and let the dye fully penetrate into the fiber. This method can make the color uniform and full, and is suitable for large-area monochrome dyeing. Another is printing dyeing, which uses printing equipment to print the dye on the surface of the carpet to form various exquisite patterns. Printing dyeing can achieve complex patterns and diverse color combinations. Another is tie-dyeing, which is to tie part of the carpet and then put it into the dye vat for dyeing. The tied part will not be dyed, thus forming a unique pattern effect. Tie-dyeing is often used to make carpets with national characteristics and artistic sense. In addition, there are methods such as hand-painted dyeing, in which professional painters use dyes to draw patterns directly on the carpet. This method can create carpet works with great personality and artistic value.

[0003] After the carpets are placed in the dye vat for centralized dyeing, they generally need to be manually fished out and transferred to a drying area by a transfer vehicle for drying and setting. However, during the transportation process after the carpets are dyed, the dye absorbed by the carpets will gradually penetrate downwards and accumulate inside the transfer vehicle's bucket. During the transportation process, as the accumulated dye comes into contact with the lower carpet, it may cause color deviation between the upper and lower carpets, affecting the color effect of the carpet.

[0004] For this reason, a transfer vehicle for carpet production is proposed. Summary of the Invention

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 creative efforts are within the scope of protection of the present invention.

[0030] See also Figures 1 to 6 The present invention provides a technical solution for a transfer vehicle for carpet production:

[0031] A transfer vehicle for carpet production, comprising:

[0032] The transfer vehicle structure 1 is mainly composed of the power system, chassis system, body structure, electrical system, transmission system and steering system;

[0033] The vehicle interior structure 2 is rotatably disposed inside the transfer vehicle structure 1 and is used to cooperate with the transfer vehicle structure 1 to perform the transfer operation of the carpet after dyeing;

[0034] The transfer vehicle structure 1 includes a vehicle body 11, an upwardly open vehicle bucket 12 is provided inside the vehicle body 11, and U-shaped pipe grooves 122 are provided on the left and right walls of the vehicle bucket 12, and a water collecting tank 121 connected to the vehicle bucket 12 is provided inside the vehicle body 11 directly below the vehicle bucket 12, and an output port for dye output is provided on one side of the water collecting tank 121 on the surface of the vehicle body 11, and a rotating shaft 13 is provided on the surface of the vehicle body 11 at the rear side of the upper port of the vehicle bucket 12 to cooperate with the bearing seat for rotation, and the other end of the rotating shaft 13 is provided. One end of the middle portion is connected to the shaft of the drive motor 131 by a coupling, wherein the drive motor 131 is fixed to the bearing seat surface of the rotating shaft 13 by bolts, and at least one hydraulic rod 132 is fixedly provided on the rod side of the rotating shaft 13 at equal intervals with an L-shaped support rod on the same side. The hydraulic rod 132 includes an outer tube, a piston rod slidably arranged inside the outer tube, and a spring sleeved on the piston rod. The unopened end of the outer tube is provided with an interface for inputting and outputting a safety liquid, and the output end of the piston rod is configured as a sphere or an arc.

[0035] The interior structure 2 includes an inner box 21. The inner box 21 is a rectangular parallelepiped structure with shafts integrally provided on both the left and right sides. An impeller is mounted on the end of the left shaft. The impeller rotates in a wheel chamber connected to the gushing liquid channel 123, and the impeller blades are driven by the hydraulic force of the safety liquid flowing through the gushing liquid channel 123. After the coated carpet is placed, a water pressure cover plate 22 is manually pushed and placed at the open end of the inner box 21. Ball-end handles are fixedly provided on the upper surface of the water pressure cover plate 22 on the front and rear sides. When the inner box 21 is rotated and inverted, the handles will contact the inner wall support of the truck bed 12. A bottom plate 23 is provided in a sliding and sealing manner in the middle and lower position inside the inner box 21, and an upper loading plate 231 is fixedly provided on the upper surface of the bottom plate 23 in conjunction with the connecting ribs, and drainage grooves 2311 for water distribution are provided in the middle position of the circumferential side of the upper loading plate 231. Among them, a through hole for water flow is provided on the surface of the connecting ribs. Several through holes are provided in sequence from left to right in the middle position of the surface of the bottom plate 23, and a valve tube 232 with a T-shaped hole inside is fixedly provided at the lower end of each through hole, and a valve stem 233 is provided in a sliding and sealing manner inside each valve tube 232. The valve stem 233 is T-shaped, and an inverted T-shaped channel is opened inside. A valve spring 2331 for sliding constraint of the valve stem 233 is sleeved on the rod body of the valve stem 233 inside the valve tube 232. The two ends of the valve spring 2331 are respectively fixed to the rod body of the valve stem 233 and the inner wall of the valve tube 232. The lower surface of the bottom plate 23 is fixed with several buffer spring rods 25 on the front and rear sides of the valve tube 232, and the buffer spring rods 25 are distributed in a straight array from left to right. The buffer spring rods 25 are a spring rod structure with telescopic ability, and the lower ends of the buffer spring rods 25 are fixed with a first Two hydraulic pistons 26, the piston end of the second hydraulic piston 26 is slidingly sealed and inserted into the interior of the second liquid flow tube 261, and the interior of the second liquid flow tube 261 stores a safety liquid (such as hydraulic oil, water-based liquid, etc.). The second hydraulic piston 26 and the second liquid flow tube 261 are externally sleeved with a second spring 262, and the two ends of the second spring 262 are respectively fixed to the inner wall of the inner box 21 and the upper end plate of the second hydraulic piston 26. All the second liquid flow tubes 261 are fixedly connected through the pipeline integrally arranged on the lower side, and are connected to the hydraulic rod 132 through the pipeline through the pipe groove 122.

[0036] During operation, the dyed carpet is manually placed flat on the surface of the loading plate 231 inside the inner box 21. As the carpet is placed in, the gravity of the carpet and the dye absorbed inside it will cause the bottom plate 23 to move downward, and the downward moving bottom plate 23 will compress the buffer spring rod 25. The compressed buffer spring rod 25 will also push the second hydraulic piston 26, causing the second hydraulic piston 26 to initially push the safety liquid inside the second liquid flow tube 261. These safety liquids enter the hydraulic rod 132, and the hydraulic rod 132 will extend and output due to the entry of the safety liquid. After the carpet is placed, the worker covers the water pressure cover plate 22 and uses components such as buckles to resist and fix it at the port. Then the drive motor 131 can be controlled to rotate the drive shaft 13. The rotating shaft 13 will drive the hydraulic rod 132 to rotate, and the output end of the hydraulic rod 132 will push on the water pressure cover plate The surface of 22 presses the water pressure cover 22. The pressed water pressure cover 22 squeezes the carpet on the surface of the upper loading plate 231, pressing out the dye absorbed in the carpet. The pressed dye will fall between the upper loading plate 231 and the bottom plate 23 through the drainage groove 2311 in the middle position of the side of the upper loading plate 231. As the amount of dye increases, the pressure of the water pressure cover 22 on the carpet by the hydraulic rod 132 increases. The pressure of the dye will act on the upper end of the valve stem 233, causing the valve stem 233 to compress the valve spring 2331 and move downward along the inner wall of the valve tube 232 until the lower end of the valve stem 233 passes through the valve tube 232. At this time, the upper part of the bottom plate 23 will be temporarily connected with the space below the bottom plate 23 through the channel inside the valve stem 233. Then the dye will quickly enter the lower part of the inner box 21 through the valve stem 233 and fall into the water collecting tank 121 for storage.

[0037] In summary, by providing the water collection tank 121 and the special in-vehicle structure 2, the dye squeezed out of the carpet after dyeing can be collected in the water collection tank 121 in time, avoiding the accumulation of dye inside the transfer vehicle bucket 12, and preventing color deviation caused by the contact of accumulated dye with the lower carpet during the transfer process, thereby ensuring the color effect of the carpet.

[0038] As an embodiment of the present invention, Figures 1 to 6 As shown, a circular wheel chamber is provided inside the vehicle body 11 on the left side of the vehicle bed 12, and a gushing liquid channel 123 is provided on the lower side of the wheel chamber. One end of the gushing liquid channel 123 penetrates the vehicle bed 12 from the rear side, and the other end of the gushing liquid channel 123 is connected to a liquid receiving chamber 124 provided inside the vehicle body 11. The radius of the liquid receiving chamber 124 is larger than the radius of the gushing liquid channel 123, and a hydraulic spring piston 125 is provided in the internal sliding seal of the liquid receiving chamber 124.

[0039] Several first liquid flow tubes 24 are fixedly arranged on the side of the buffer spring rod 25 away from the valve tube 232 at the lower part of the inner box 21. The internal sliding seal of the first liquid flow tube 24 is provided with a first hydraulic piston 241, and the outer sleeve of the first liquid flow tube 24 and the first hydraulic piston 241 is provided with a first spring 242. The structural arrangement and distribution of the first liquid flow tube 24, the first hydraulic piston 241 and the first spring 242 are the same as the structural arrangement and distribution of the second hydraulic piston 26, the second liquid flow tube 261 and the second spring 262, and the first liquid flow tube 24 is fixedly connected to one end of the gushing liquid channel 123 through a pipeline, and an electric control valve is installed at the connecting port. The height setting of the first liquid flow tube 24, the first hydraulic piston 241 and the first spring 242 is smaller than the height setting of the second hydraulic piston 26, the second liquid flow tube 261 and the second spring 262. A through drain outlet is opened at the lower part of the inner box 21 corresponding to the water collecting tank 121.

[0040] The hydraulic rod 132 continuously applies pressure, and the pressure plate 22 and the carpet press the bottom plate 23, thereby squeezing the second hydraulic piston 26 and the first hydraulic piston 241. The second hydraulic piston 26 squeezes the liquid in the second liquid flow pipe 261, causing the hydraulic rod 132 to extend further, intensifying the pressure. The first hydraulic piston 241 squeezes the liquid in the first liquid flow pipe 24 into the gushing liquid channel 123. At this time, the electric control valve opens, and the safety liquid flows into the gushing liquid channel 123, pushing the impeller at the left end of the inner box 21, so that the inner box 21 The vehicle is flipped over and the motor 131 is driven to reverse the shaft 13, driving the hydraulic rod 132 to reset and separate from the water pressure cover plate 22. The liquid entering the liquid gushing channel 123 compresses the hydraulic spring piston 125 and is stored in the liquid receiving chamber 124. The electric control valve is then closed. After the inner box 21 is inverted, the internal carpet and structure move downward, and the carpet falls on the water pressure cover plate 22. The water pressure cover plate 22 is supported at the bottom of the vehicle body 11 by the handle and blocks the port of the inner box 21. The remaining dye on the carpet is impregnated with the carpet below under the action of gravity.

[0041] In summary, by providing the sump 121 and the special interior structure 2, and utilizing the hydraulic system and hydraulic drive principles, when the hydraulic rod 132 applies pressure to cause the first hydraulic piston 241 to squeeze liquid into the influx channel 123, the impeller is pushed to flip the inner box 21. Simultaneously, the drive motor 131 is driven in reverse to reset the hydraulic rod 132. After the inner box 21 is inverted, the remaining carpet dye, under the action of gravity, impregnates the carpet below, achieving secondary dyeing and helping to ensure dyeing uniformity.

[0042] Working principle: During operation, the dyed carpet is carefully placed flat on the surface of the upper loading plate 231 inside the inner box 21. Due to the weight of the carpet itself and the weight of the dye absorbed inside, downward pressure is exerted on the bottom plate 23, causing the bottom plate 23 to move downward. During the downward movement of the bottom plate 23, the buffer spring rod 25 on its lower surface is compressed. After the buffer spring rod 25 is compressed, it transmits force to the second hydraulic piston 26 connected to it, pushing the second hydraulic piston 26 to slide in the second liquid flow pipe 261. At this time, the second hydraulic piston 26 initially pushes the safety liquid stored in the second liquid flow pipe 261. Under the action of pressure, this safety liquid enters the hydraulic rod 132 through the pipe groove 122 through the pipeline. Inside the outer tube of the hydraulic rod 132, the piston rod overcomes the spring resistance under the pressure of the safety liquid and partially extends for output.

[0043] After the carpet is placed, the worker pushes the water pressure cover plate 22 horizontally to the open port of the inner box 21, and firmly fixes it with components such as buckles to prevent the water pressure cover plate 22 from shifting during subsequent operations. Then, the drive motor 131 is started. The drive motor 131 drives the rotating shaft 13 to rotate through the coupling. The rotation of the rotating shaft 13 causes the hydraulic rod 132 fixed on the side of its rod to rotate accordingly. During the rotation process, the output end extended by the hydraulic rod 132 will gradually push on the surface of the water pressure cover plate 22. As the rotating shaft 13 continues to rotate, the pressure of the hydraulic rod 132 on the water pressure cover plate 22 continues to increase. After being compressed, the water pressure cover plate 22 will evenly transfer the pressure to the carpet on the surface of the upper loading plate 231, squeezing the carpet so that the dye absorbed inside the carpet is squeezed out, and the squeezed dye will flow along the drainage groove 23 in the middle position of the side edge of the upper loading plate 231. 11, flows to between the upper loading plate 231 and the bottom plate 23, as the dye continues to accumulate, the pressure it generates on the upper surface of the bottom plate 23 gradually increases. When the pressure reaches a certain level, it acts on the upper end of the valve stem 233. The valve stem 233 is T-shaped. Under the action of pressure, it overcomes the elastic force of the valve spring 2331 and slides downward along the inner wall of the valve tube 232. The valve spring 2331 is compressed until the lower end of the valve stem 233 passes through the valve tube 232. At this time, the upper part of the bottom plate 23 is temporarily connected to the space below the bottom plate 23 through the inverted T-shaped hole inside the valve stem 233. The dye accumulated between the upper loading plate 231 and the bottom plate 23, under the combined action of the pressure difference and gravity, quickly enters the lower part of the inner box 21 through the valve stem 233 and finally falls into the sump 121 for storage, thereby preventing the accumulation of dye from affecting the carpet in the inner box 21.

[0044] As the hydraulic rod 132 continues to apply pressure, the pressure it applies to the bottom plate 23 through the water pressure cover plate 22 and the carpet further increases, which causes the second hydraulic piston 26 to be subjected to stronger pressure, thereby further compressing the safety liquid inside the second liquid flow pipe 261 to be output, and more safety liquid enters the hydraulic rod 132, prompting the hydraulic rod 132 to further extend and output, and the pressure on the water pressure cover plate 22, the carpet and the bottom plate 23 is also further enhanced. At the same time, when the bottom plate 23 is subjected to greater pressure, it will transmit force to the first hydraulic piston 241. The first hydraulic piston 241 slides in the first liquid flow pipe 24, compressing the safety liquid inside the first liquid flow pipe 24, causing it to enter the gushing liquid channel 123. At this time, the electric control valve at the port connecting the first liquid flow pipe 24 and the gushing liquid channel 123 opens after receiving the control signal. The safety liquid flowing into the gushing liquid channel 123 has a certain flow rate and pressure, which will impact the inner box. The impeller installed at the end of the left end of the shaft 21 starts to rotate under the hydraulic drive. Since the impeller is connected to the left side shaft of the inner box 21, the rotation of the impeller drives the inner box 21 to flip around its own shaft. While controlling the flipping of the inner box 21, the driving motor 131 rotates in the opposite direction, and drives the rotating shaft 13 to rotate in the opposite direction through the coupling. The reverse rotation of the rotating shaft 13 causes the hydraulic rod 132 to rotate and reset, separate from the water pressure cover plate 22, and release the pressure on the water pressure cover plate 22, and the safety liquid entering the gushing liquid channel 123, after pushing the impeller, continues to flow in the pipeline, and finally flows into the liquid receiving chamber 124. The radius of the liquid receiving chamber 124 is larger than the radius of the liquid gushing liquid channel 123. After the safety liquid flows in, it compresses the hydraulic spring piston 125 provided with a sliding seal inside the liquid receiving chamber 124, and stores the safety liquid in the liquid receiving chamber 124. At this time, the electric control valve closes the gushing liquid channel 123 after receiving the signal to prevent the safety liquid from flowing back.

[0045] After the inner box 21 is flipped to an inverted state, the carpet and other structures inside will move downward under the action of gravity, and the carpet will fall on the surface of the water pressure cover 22. The water pressure cover 22 is supported at the bottom of the vehicle body 11 through the ball-end handles fixed on the front and rear sides of its surface, thereby blocking the port of the inner box 21 and preventing the items inside from falling. At this time, the remaining dye inside the carpet will gradually spread downward under the action of gravity. Since the inner box 21 is in an inverted state, the carpet below will be dyed by the remaining dye, thereby achieving further dyeing treatment of the carpet and ensuring the uniformity of the dyeing effect. When the transfer vehicle arrives at the dryer position, the electric control valve receives the control signal to open again, and the liquid stored in the liquid collection chamber 124 is stored. The full liquid, under the elastic force of the hydraulic spring piston 125, quickly flows back to the surging liquid channel 123. The reflux safety liquid has a certain impact force, which will push the impeller to rotate in the opposite direction, and then drive the inner box 21 to reverse and reset. The safety liquid flows into the interior of the first liquid flow pipe 24 again through the pipeline, completing the liquid circulation. Then, the worker manually releases the buckle constraint of the water pressure cover 22 at the port and removes the water pressure cover 22 from the inner box 21. Then, the carpet above the drainage groove 2311 of the upper loading plate 231 is taken out, and the carpet is sorted to remove possible wrinkles, impurities, etc., and then the sorted carpet is sent to the dryer for drying, completing the entire process of the carpet from dyeing to transportation to drying.

[0046] It should be noted that the control of the drive motor 131, the solenoid valve, etc. can be preset and adjusted according to the movement process of the transfer vehicle, the state of the carpet and the vehicle interior structure 2.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
