Description

Technical Field

[0001] The invention relates to the technical field of carpet production, in particular to a uniform dyeing device for carpet production. Background Art

[0002] The carpet production process is relatively complicated and usually includes the following main steps. The first is design. The pattern, color and style of the carpet are designed according to market demand and customer requirements. The second step is raw material selection. Common carpet raw materials include wool, chemical fiber, silk, etc. Different raw materials have different properties and textures. The next step is spinning. The selected raw materials are spun into yarn suitable for weaving. Weaving is a key link in carpet production. Common weaving methods are hand weaving and machine weaving. Hand-woven carpets have exquisite craftsmanship and delicate patterns, but the output is low; machine weaving is more efficient and can be produced on a large scale. During the weaving process, the yarns are interwoven into the basic shape and pattern of the carpet according to the design requirements. After that, the woven carpet is trimmed to make its surface smooth, remove excess thread ends and burrs, and perform final finishing, including quality inspection and defect repair.

[0003] 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.

[0004] However, in the current carpet production process, before the printing and dyeing equipment is put into use, the adjustment and debugging of the printing and dyeing components usually rely on manual operation. In order to achieve uniform printing and dyeing effects and ensure product quality, operators not only need to receive professional training from the equipment manufacturer and follow the manufacturer's guidance during the debugging process, but also need to have strong learning ability, which undoubtedly increases the complexity and difficulty of operation. In addition, in most carpet production processes, the dye addition link is also handled manually, which requires workers to always pay attention to the operating status of the printing and dyeing machine and replenish the dye in time according to the remaining dye to avoid affecting the production progress and product quality due to insufficient dye. Manual operation not only consumes manpower and energy, but also makes it difficult to ensure the accuracy and stability of the operation, and is prone to human errors.

[0005] Therefore, a uniform dyeing device for carpet production is proposed. Summary of the Invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention adopts the arrangement of the printing and dyeing structure. During the debugging stage before printing and dyeing, when the printing and dyeing structure moves downward, the pressing block contacts the printing and dyeing table and the carpet of the carpet printing and dyeing machine. As the printing and dyeing structure continues to move downward, the pressing block, under the reverse support, pushes the printing and dyeing screen and the clamping frame upward to stop them from moving, while the linear moving module, the moving slide, the screen moving frame and their connecting structure continue to move downward. During this process, the downward moving pressure liquid pipe squeezes the internal safety liquid into the cylinder, pushing the pneumatic piston to drive the scraper plate and the return scraper upward and away from the printing and dyeing screen plate. In addition, when the thickness of the carpet pile is different, the relative movement distance of the screen moving frame and the clamping frame will change accordingly. The paint amount scraped by the scraper is automatically adjusted according to the change, ensuring uniform dyeing for different carpet materials, avoiding the complex operation and errors of manual debugging, and improving the accuracy and stability of printing and dyeing. At the same time, when the printing and dyeing structure is pushed to the maximum transmission distance, the pressing block compresses the circulating spring and moves upward, pushing the safety liquid in the liquid storage chamber into the valve body, so that the valve cone is inserted into the fixing groove of the spring insert rod, realizing the automatic limitation of the distance between the screen moving frame and the clamping frame after adjustment. This automatic adjustment mechanism not only saves manpower, but also ensures the accuracy of the relative positions of various components during the printing and dyeing process, providing reliable guarantee for subsequent stable and efficient printing and dyeing operations.

[0020] 2. The present invention sets a printing and dyeing structure. During the printing and dyeing process, the printing and dyeing structure moves downward. The movement of the pressing block will push the safety liquid in the liquid storage chamber into the top pipe through the valve body and the circulating liquid channel in turn, pushing the double-headed piston to move upward, further compressing the color paste and dye in the feeding pipe, so that the output one-way valve is opened to replenish the dye to the liquid feeding tank. With this process, the continuous supply of color paste and dye to the mesh surface of the printing and dyeing screen can be ensured during each printing and dyeing process. This automatic feeding method avoids the tedious work of manually paying attention to the dye residue and manually adding dye, reduces the situation where insufficient dye causes the impact on production progress and product quality due to untimely manual operation, ensures the stability of dye supply during the printing and dyeing process, and thus improves the overall quality and production efficiency of carpet printing and dyeing.

The connecting auxiliary rod 235 located at the corner position is movably connected to the clamping frame 231, wherein the spring insertion rod 232 is composed of a rod body slidably inserted into the pre-opened insertion hole of the wire mesh moving frame 23 and a spring sleeved on the rod body, and the upper and lower ends of the spring are respectively fixed to the lower surface and upper surface of the wire mesh moving frame 23 and the clamping frame 231. At least one pressure liquid pipe 233 is provided, which is fixed to the bottom surface of the wire mesh moving frame 23. The pressure liquid pipe 233 stores a safety liquid, and a hydraulic piston 2331 with a lower end fixed to the clamping frame 231 is slidably and sealedly provided below the safety liquid;

[0042] One end of the circulating fluid channel 2375 is connected to the valve body 237 opened on the side of the spring plug rod 232 near the movable slide 22 inside the clamping frame 231. A valve seat 2371 is fixedly provided on the side of the valve body 237 at the communication port with the circulating fluid channel 2375 near the movable slide 22. A platform-shaped valve hole is opened inside the valve seat 2371, and a valve cone 2372 is sealed and inserted inside the valve hole. The valve cone 2372 is spindle-shaped and is fixed to the valve seat 2371 when it is in contact with the valve seat 2371. The upper and lower sides of the relative cone end 71 are slidably attached with elastic arc-shaped elastic clamping plates 2373, and the upper and lower wall surfaces of the valve body 237 are provided with grooves for covering the elastic clamping plates 2373. The elastic clamping plates 2373 are bound with pull wires 2374 on the opposite side in contact with the valve cone 2372, and the pull wires 2374 are inserted into the corresponding sealing wire holes opened inside the wire mesh moving frame 23, and the pull wires 2374 pass through the wire ends of the wire mesh moving frame 23. A finger ring is fixedly provided, and the two ends of the valve body 237 are open to the insertion hole of the spring plug rod 232 and the direction of the movable slide 22 respectively. Among them, the port open to the insertion hole of the spring plug rod 232 is provided with a sealed truncated cone shape according to the valve cone 2372, and the port open to the movable slide 22 is equipped with an interface. The surface of the spring plug rod 232 corresponds to the valve cone 2372 and is provided with a plurality of fixed grooves 2321 in a straight line array. The interface of the valve body 237 is connected to the printing and dyeing through a pipeline. The liquid storage chambers 241 opened inside the left and right side frames of the screen 24 are connected, and the interior of the liquid storage chamber 241 is equipped with a plurality of circulating springs 242 for sliding sealing to limit the setting of a clamping block 243, and initially, the lower surface of the clamping block 243 is lower than the lower surface of the printing and dyeing screen 24, and the left and right side frames of the printing and dyeing screen 24 are detachably fixed to the clamping frame 231, and initially, the scraper plate 222 and the return scraper plate 223 are adjacent to or in contact with the surface of the printing and dyeing screen 24.

[0043] During operation, the carpet to be printed and dyed is first sent to the bottom of the printing and dyeing structure 2 through the conveying system of the printing and dyeing table of the carpet printing and dyeing machine 1. Then, the printing and dyeing structure 2 is adjusted according to the size of the carpet. During adjustment, the transmission system of the carpet printing and dyeing machine 1 is started on the console to make the printing and dyeing structure 2 move down, and the pressing block 243 first contacts the printing and dyeing table and the carpet. When the printing and dyeing structure 2 continues to move down, the pressing block 243 is supported in the reverse direction and pushes the printing and dyeing screen 24 and the clamping frame 231 upward to stop them from moving. The linear moving module 21, the moving slide 22, the screen moving frame 23 and their connecting structure continue to move down. In this process, the downward-moving pressure liquid pipe 233 squeezes the internal safety liquid to make it enter the cylinder 221, pushing the pneumatic piston 2212 to drive the scraper plate 222 and the return scraper 223 to move up and away from the printing and dyeing screen 24. The thicker the carpet pile, the greater the distance the screen moving frame 23 and the clamping frame 231 move toward each other. The more safety liquid is forced into the cylinder 221 by the pressure pipe 233 and the hydraulic piston 2331, the more paint is spread by the scraper 222, ensuring the dyeing effect. The downward-moving feeding pipe 234 compresses the hydraulic spring 2342 and, as the double-headed piston 2343 moves downward, the internal dye is compressed. When the hydraulic pressure reaches the opening pressure of the output check valve 2341, the dye is input into the liquid replenishing tank 224, completing the initial dye replenishment. When the printing and dyeing structure 2 is pushed to the maximum transmission distance, the pressing block 243 compresses the circulating spring 242 and moves upward, pushing the safety liquid in the liquid storage chamber 241 into the valve body 237. The valve cone 2372 is pushed out, squeezes the elastic clamping plate 2373, and then inserts into the fixing groove 2321 of the spring insert rod 232, thereby limiting the distance between the screen moving frame 23 and the clamping frame 231. After completing the above-mentioned automatic adjustment, the printing and dyeing structure 2 is controlled by the console to enter the printing and dyeing state, and the carpet can be printed and dyed.

[0044] In summary, through the setting of the printing and dyeing structure 2, in the debugging stage before printing and dyeing, when the printing and dyeing structure 2 moves downward, the pressing block 243 contacts the printing and dyeing table and carpet of the carpet printing and dyeing machine 1. As the printing and dyeing structure 2 continues to move downward, the pressing block 243, under the reverse support action, pushes the printing and dyeing screen 24 and the clamping frame 231 upward to stop them from moving, while the linear moving module 21, the moving slide 22, the screen moving frame 23 and their connecting structure continue to move downward. During this process, the downward-moving pressure liquid pipe 233 squeezes the internal safety liquid into the cylinder 221, pushing the pneumatic piston 2212 to drive the scraper plate 222 and the return scraper 223 to move upward, away from the printing and dyeing screen 24. In addition, when the thickness of the carpet pile is different, the screen moving frame 23 and the clamping frame 231 move toward each other. The distance will change accordingly, and the amount of paint scraped by the scraper plate 222 will be automatically adjusted to ensure uniform dyeing on different carpet materials, avoiding the complex operations and errors of manual debugging, and improving the accuracy and stability of printing and dyeing. At the same time, when the printing and dyeing structure 2 is pushed to the maximum transmission distance, the pressing block 243 compresses the circulating spring 242 to move upward, pushing the safety liquid in the liquid storage chamber 241 into the valve body 237, so that the valve cone 2372 is inserted into the fixing groove 2321 of the spring insert rod 232, thereby realizing the automatic limitation of the distance between the screen moving frame 23 and the clamping frame 231 after adjustment. This automatic adjustment mechanism not only saves manpower, but also ensures the accuracy of the relative positions of various components during the printing and dyeing process, providing reliable guarantee for subsequent stable and efficient printing and dyeing operations.

[0045] As an embodiment of the present invention, Figure 8As shown, at least one feeding pipe 234 is provided, which is fixed between the pressure liquid pipe 233 on the bottom surface of the wire mesh moving frame 23, and a one-way valve 2341 is symmetrically installed on the upper side of the side of the pipe along the axis, and a hydraulic spring 2342 and a double-headed piston 2343 are provided inside the feeding pipe 234 for upward and downward movement, wherein the upper and lower ends of the hydraulic spring 2342 are fixed to the upper wall of the feeding pipe 234 and the upper end of the double-headed piston 2343 respectively, the double-headed piston 2343 is slidingly sealed inside the feeding pipe 234, and the lower end slidingly sealed inside the top pipe 2344, an interface for safe liquid output is provided on the upper side of the pressure liquid pipe 233 facing the movable slide 22, and the interface of the pressure liquid pipe 233 is connected to the interface at the lower side of the cylinder 221 on the adjacent side through a pipeline, and the opening direction of the one-way valve 2341 is opposite, The one-way valve 2341 close to the movable slide 22 is configured to open outward to output dye, and the output one-way valve 2341 is connected to the input interface of the liquid pump 236 through a pipeline. The liquid pump 236 is fixed to the upper surface of the screen movable frame 23 by bolts, and the output interface is connected to the input interface of the liquid replenishing tank 224 through a pipeline. The top pipe 2344 is fixed to the upper surface of the clamping frame 231, and the upper end of the top pipe 2344 is slidably inserted into the bottom of the feeding pipe 234, and the upper pipe end inserted into the feeding pipe 234 is pushed on the lower surface of the double-headed piston 2343. A hydraulic interface 2345 connected to the inside of the pipe is provided on the lower side of the top pipe 2344 facing the movable slide 22, and the hydraulic interface 2345 is sealed and connected to the circulating liquid channel 2375 opened in the clamping frame 231 near the side of the movable slide 22 through a pipeline.

[0046] During printing and dyeing, the printing and dyeing structure 2 is controlled by the console of the carpet printing and dyeing machine 1 to enter the automatic printing and dyeing operation. The linear moving module 21 first transfers the movable slide 22 and its connecting structure to the left, so that the scraper plate 222 is on the left side of the printing and dyeing range of the printing and dyeing screen 24 and can cover the printing and dyeing mesh and the printing and dyeing surface of the carpet. Then it is driven to move to the right, and the scraper plate 222 and the return scraper 223 are squeezed to allow the printing and dyeing paste to pass through the mesh and be dyed on the carpet; before printing and dyeing, the printing and dyeing structure 2 moves down, the pressing block 243 contacts the carpet, and the compressed circulating spring 242 moves up under the push of the transmission system, pushing the liquid storage chamber The safety liquid in 241 enters the top pipe 2344 through the valve body 237 and the circulating liquid channel 2375 in sequence, pushing the double-headed piston 2343 upward, compressing the hydraulic spring 2342 and the color paste and dye in the feeding pipe 234, so that the output one-way valve 2341 is opened, and the color paste and dye are input into the liquid replenishing tank 224 for replenishment, and the color paste is dispersed onto the mesh surface of the printing and dyeing screen 24; after printing and dyeing, the printing and dyeing structure 2 is reset, the double-headed piston 2343 is reset under the action of the hydraulic spring 2342, and the pressing block 243 is reset under the action of the circulating spring 242, and then the next printing and dyeing can be carried out until the carpet printing and dyeing is completed.

[0047] To sum up, through the setting of the printing and dyeing structure 2, during the printing and dyeing process, the printing and dyeing structure 2 moves downward, and the movement of the pressing block 243 will push the safety liquid in the liquid storage chamber 241 into the top pipe 2344 through the valve body 237 and the circulating liquid channel 2375 in sequence, pushing the double-headed piston 2343 to move upward, further compressing the color paste dye in the feeding pipe 234, so that the output one-way valve 2341 opens, and replenishes the dye to the liquid replenishing tank 224. With this process, during each printing and dyeing process, the continuous supply of color paste dye to the mesh surface of the printing and dyeing screen 24 can be ensured. This automatic feeding method avoids the tedious work of manually paying attention to the dye residue and manually adding dye, reduces the situation where insufficient dye causes the production progress and product quality to be affected due to untimely manual operation, ensures the stability of dye supply during the printing and dyeing process, and thus improves the overall quality and production efficiency of carpet printing and dyeing.

[0048] Working principle: When working, the carpet to be printed and dyed is first transported to the bottom of the printing and dyeing structure 2 through the conveying system on the printing and dyeing table of the carpet printing and dyeing machine 1, and then the printing and dyeing structure 2 is debugged according to the size of the carpet. During the debugging process, it is first necessary to start the transmission system through the console on the carpet printing and dyeing machine 1. The transmission system will transmit the printing and dyeing structure 2 downward. When the printing and dyeing structure 2 moves downward, the pressing block 243 will first contact the printing and dyeing table of the carpet printing and dyeing machine 1 and the carpet on the printing and dyeing table. Then, as the printing and dyeing structure 2 continues to move downward under the transmission of the carpet printing and dyeing machine 1, the pressing block 243 will play a reverse supporting role between the printing and dyeing table and the carpet. The printing and dyeing screen 24 is supported upward, and then the printing and dyeing screen 24 and the clamping frame 231 fixed to the printing and dyeing screen 24 stop moving under the supporting action of the pressing block 243. At this time, the linear moving module 21, the moving slide 22, the screen moving frame 23 and the structure connected thereto continue to move downward under the transmission system of the carpet printing and dyeing machine 1. As the screen moving frame 23 moves downward, it will synchronously drive the pressure liquid pipe 233 and the feeding pipe 234 fixed on the bottom surface to move downward, and compress the spring sleeved on the spring insertion rod 232, so that the insertion rod of the spring insertion rod 232 further passes upward through the screen moving frame 23.

[0049] The downward-moving pressure liquid pipe 233 will utilize the opposite movement with the hydraulic piston 2331 to squeeze the safety liquid stored in the pressure liquid pipe 233, forcing the safety liquid stored in the pressure liquid pipe 233 to enter the interior of the cylinder 221 connected thereto through the pipeline through the side interface, and flow into the lower side of the air pressure piston 2212, pushing the air pressure piston 2212 upward, so that the air pressure piston 2212 moves upward along the inner wall of the cylinder 221, and the upward-moving air pressure piston 2212 will synchronously drive the scraper plate 222 and the return material scraper 223 to move upward, so that the scraper plate 222 and the return material scraper 223 move away from the printing and dyeing surface of the printing and dyeing screen 24. At this time, the thicker the pile thickness of the carpet, the more dye is required. When the carpet printing and dyeing machine 1 pushes the linear moving module 21, the moving slide 22, the screen moving frame 23 and their connecting structure downward by an unchanged distance (carpet printing and dyeing machine 1 The maximum distance reached by the internal transmission system of the dyeing machine 1 pushing the printing and dyeing structure 2 downward or the maximum stroke of the transmission system of the carpet printing and dyeing machine 1 (at this time, the state in which the printing and dyeing screen 24 is attached to the carpet surface and dyeing is being performed) is reached. When the carpet printing and dyeing machine 1 pushes the linear moving module 21, the movable slide 22, the screen moving frame 23 and their connecting structure downward to the lowest point, the screen moving frame 23 and the clamping frame 231 move toward each other. The more safety liquid is pressed into the cylinder 221 between the pressure liquid pipe 233 and the hydraulic piston 2331 connected thereto, the longer the distance the pneumatic piston 2212 moves upward, the greater the distance between the scraper plate 222 and the return scraper plate 223 and the mesh surface of the printing and dyeing screen 24, and the more paint is scraped onto the mesh surface of the printing and dyeing screen 24 when the scraper plate 222 scrapes the paint. This ensures a uniform dyeing effect and dyeing quality when the carpet is printed and dyed by the printing and dyeing screen 24.

[0050] The downward moving feeding pipe 234 compresses the hydraulic spring 2342 and moves downward along the wall of the top pipe 2344, so as to synchronously adjust the distance between the screen moving frame 23 and the clamping frame 231 after the distance is changed. At the same time, as the feeding pipe 234 moves downward, since the double-headed piston 2343 does not move, the dye already drawn into the feeding pipe 234 is compressed during the process of the feeding pipe 234 and the double-headed piston 2343 moving toward each other (during the first debugging and use, it is necessary to manually replenish the feeding pipe 234 with dye through the input one-way valve 2341 or directly add a certain amount of dye into the liquid replenishing tank 224). As the dye in the feeding pipe 234 is squeezed, the hydraulic pressure in the feeding pipe 234 increases and reaches the opening pressure of the output one-way valve 2341. Then, the dye is input into the liquid replenishing tank 224 through the pipeline from the output one-way valve 2341, and the liquid replenishing tank 224 is replenished with dye for the first time.

[0051] When the transmission system of the carpet printing and dyeing machine 1 pushes the printing and dyeing structure 2 downward to reach the maximum transmission distance, the pressing block 243 will reach the deformation pressure of the circulating spring 242 under the reverse force of the carpet and the printing and dyeing table of the carpet printing and dyeing machine 1, so that the pressing block 243 compresses the circulating spring 242 and moves upward along the inner wall of the liquid storage chamber 241. The upward moving pressing block 243 will push the safety liquid inside the liquid storage chamber 241 into the interior of the valve body 237 through the pipeline, and the valve cone 2372 inside the valve body 237 will slide out from the inside of the valve seat 2371 along the inner wall of the valve body 237 under the pushing action of the influx of safety liquid. During the movement, the valve cone 2372 will squeeze the elastic clamping plate 2373 upward and downward until the valve cone 2372 is away from the printing and dyeing screen 24 The cone end of the valve cone 2372 moves through the elastic clamping plate 2373, and the cone end close to the printing and dyeing screen 24 contacts the elastic clamping plate 2373. Then, the valve cone 2372 is pushed by the elastic clamping plate 2373, so that the cone end of the valve cone 2372 away from the printing and dyeing screen 24 passes through the interior of the valve body 237 and is inserted into the inside of the side insertion groove 2321 of the spring insertion rod 232 after further passing through the screen moving frame 23 upwards. The spring insertion rod 232 is positioned after further passing through the screen moving frame 23 upwards, so that the adjustment of the distance between the screen moving frame 23 and the clamping frame 231 can be achieved. In summary, the printing and dyeing structure 2 can be automatically adjusted during printing and dyeing. After adjustment, the printing and dyeing structure 2 can be controlled to enter the printing and dyeing state through the console of the carpet printing and dyeing machine 1, so that the carpet can be printed and dyed.

[0052] During printing and dyeing, the printing and dyeing structure 2 can first be controlled by the console of the carpet printing and dyeing machine 1 to enter the automatic printing and dyeing operation, and then the linear moving module 21 of the printing and dyeing structure 2 will transmit the movable slide 22 and the structure connected thereto to move to the left position, and the position of the scraper plate 222 will be on the left side of the printing and dyeing range of the printing and dyeing screen 24 for the carpet. The moving range of the scraper plate 222 can fully cover the printing and dyeing mesh of the printing and dyeing screen 24 and the printing and dyeing surface of the carpet, and then the linear moving module 21 will drive the movable slide 22 and the structure connected thereto to move to the right, and during the moving process, the movable slide 22 and the structure connected thereto will move to the left side. During the printing process, the scraper plate 222 and the return scraper plate 223 are squeezed to make the printing and dyeing paste pass through the mesh holes on the printing and dyeing screen 24 and transfer to the carpet surface, forming the same pattern and color as the original. In this process, before the carpet is printed, the printing and dyeing structure 2 moves downward, and the pressing block 243 will first contact the carpet. Under the push of the transmission system of the carpet printing and dyeing machine 1, the deformation pressure of the circulating spring 242 is reached, so that the pressing block 243 compresses the circulating spring 242 and moves upward along the inner wall of the liquid storage chamber 241. The upward pressing block 243 pushes the liquid storage chamber 241. The safety liquid in the upper part enters the interior of the valve body 237 through the pipeline, and enters the interior of the circulating liquid channel 2375 along the valve body 237. The safety liquid entering the circulating liquid channel 2375 will enter the interior of the top pipe 2344 through the pipeline, and push the lower end of the double-headed piston 2343 to move upward along the wall of the top pipe 2344. The upward-moving double-headed piston 2343 will press the hydraulic spring 2342 and the color paste dye inside the feeding pipe 234, and reach the opening pressure of the output one-way valve 2341. Then the one-way valve 2341 will open to release the pressure, and the color paste dye inside the feeding pipe 234 will be discharged. The color paste dye is input into the replenishing tank 224 through the pipeline to replenish the color paste dye, and then the color paste will be dispersed from the lower port inside the replenishing tank 224 and fall onto the mesh surface of the printing and dyeing screen 24. After printing and dyeing, the printing and dyeing structure 2 will be reset under the control of the carpet printing and dyeing machine 1 (the movable slide 22 and its connecting structure will move to the left side of the printing and dyeing screen 24), and the double-headed piston 2343 will be reset under the action of the hydraulic spring 2342, and the pressing block 243 will be reset under the action of the circulating spring 242, and then the next carpet printing and dyeing can be carried out until the carpet printing and dyeing is completed.
