Description

Technical Field

[0001] The invention relates to the technical field of chemical fiber cloth printing and dyeing, in particular to a printing and dyeing device for processing textile chemical fiber cloth. Background Art

[0002] Textile chemical fiber cloth is a pure, blended or interwoven fabric made of chemical fiber, that is, a fabric woven from pure chemical fiber, excluding blended and interwoven fabrics with natural fibers. Chemical fiber cloth is widely used in the production of outer protective covers of sofas because of its light weight and high wear resistance. Plain sofas are generally considered to be more classic and durable, not easy to go out of style, giving people a sense of simplicity and tranquility, and helping to create a relaxing and comfortable living environment. Therefore, the textile chemical fiber cloth used to make the outer protective cover of the sofa is mostly a single color. In order to color the textile chemical fiber cloth, printing and dyeing equipment is required. The printing and dyeing methods of printing and dyeing equipment can be divided into two types: immersion dyeing and pad dyeing. Considering the dyeing cost of the outer protective cover of the sofa, the immersion dyeing method is often used to dye the textile chemical fiber cloth used for the outer protective cover of the sofa.

[0003] The dyeing process is divided into several steps, including pre-treatment, dyeing, dyeing, washing after dyeing and post-treatment. During the dyeing process, when the chemical fiber cloth leaves the dye solution, the water is squeezed out by squeezing. Since the dye adheres to the chemical fiber cloth, the concentration of the dye solution in the printing and dyeing equipment gradually decreases, so it is necessary to replenish the high-concentration dye solution in time. Due to the limited volume of the dye solution added at a time, the high-concentration dye solution added directly is easy to accumulate in a local position in the dyeing equipment, resulting in uneven distribution of the dye solution; and the dyes and auxiliaries in the bottom dye solution will settle during the long-term printing and dyeing process, causing the dye solution concentration to fail to reach the set value, resulting in color difference in the local position or the whole of the chemical fiber layout after subsequent dyeing, and the dyeing quality of the outer protective cover of the solid color sofa cannot be ensured.

[0004] Therefore, a printing and dyeing equipment for processing textile chemical fiber cloth is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a printing and dyeing equipment for processing textile chemical fiber cloth, which solves the problem of uneven distribution of dye liquid caused by directly adding high-concentration dye liquid into the dyeing frame, and avoids the problem that the concentration of the dye liquid cannot reach the set value due to precipitation of the bottom dye liquid, and has the effect of fully ensuring the uniformity of the dye liquid in the dyeing process, and effectively ensuring the dyeing uniformity of the outer protective cover of the solid-color sofa.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A printing and dyeing device for processing textile chemical fiber cloth, comprising a printing and dyeing frame, a traction roller, a partition, a rotating roller, a driving motor, and also comprising a circulation slot, a driving component, a horizontal rack, a diluted dye solution adding component, a straight slot, a gathering component, a spoiler and a reflux component, wherein the four circulation slots are arranged on both sides of the printing and dyeing frame in pairs, the two driving components are arranged on both sides of the printing and dyeing frame respectively, and the two driving components are transmission-connected, the two horizontal racks are respectively fitted and installed on the inner sides of the two driving components, the diluted dye solution adding component is plugged into the driving component, and the diluted dye solution adding component is connected to the horizontal rack, the straight slot is arranged on both sides of the printing and dyeing frame, the gathering component is equidistantly installed on the inner side of the printing and dyeing frame, and adjacent gathering components are transmission-connected, the spoiler is hinged to the inner bottom surface of the printing and dyeing frame, and the spoiler is rotationally connected to the gathering component, the reflux component is installed between the two circulation slots on the same side of the printing and dyeing frame, one of the gathering components is transmission-connected to the driving component and the reflux component at the same time, and the driving motor is connected to one of the gathering components;

[0008] When the driving motor drives the gathering component to rotate, the driving component and the reflux component are started synchronously. When the driving component drives the diluted dye liquid adding component to move linearly, the diluted dye liquid adding component injects dye into the printing and dyeing frame at a uniform speed. When the gathering component rotates, the dye is gathered toward the axis side of the printing and dyeing frame, and the gathering component drives the spoiler to swing up and down to push the dye toward the partition side. At the same time, the reflux component drives the dye at the partition to flow toward the inner end of the printing and dyeing frame.

[0009] In the above scheme, when it is necessary to put high-concentration dye liquid into the printing and dyeing frame to increase the dye liquid concentration in the printing and dyeing frame to the set printing and dyeing concentration, the high-concentration dye liquid is diluted according to the proportion and loaded into the diluted dye liquid adding component. When the driving motor drives multiple gathering components to start, the gathering component simultaneously drives two driving components as well as the gathering component and the reflux component to start. The driving component drives the diluted dye liquid adding component to move horizontally at a uniform speed along the outer wall of the printing and dyeing frame, and extrude the diluted dye liquid into the printing and dyeing frame at a constant speed during the uniform speed process, thereby achieving uniform delivery of the dye liquid. The gathering component drives the entire dye liquid in the printing and dyeing frame to move from the side close to the reflux component to the axis side of the printing and dyeing frame, and at the same time drives one end of the spoiler to move up and down continuously, so that the added dye liquid is further fully mixed with the original dye liquid, and combined with the effects of the reflux component and the spoiler, the dye liquid circulates in the printing and dyeing frame, and the bottom dye liquid also participates in the circulation flow to avoid dye precipitation, thereby fully ensuring the uniformity of the dye liquid in the printing and dyeing frame, and then effectively ensuring the dyeing uniformity and dyeing quality of the outer protective cover of the solid color sofa.

[0010] Preferably, the bottom surface of the straight groove is inclined, and a plurality of dye liquid guiding grooves that fit together are constructed on the bottom surface of the straight groove.

[0011] When the dye drops onto the bottom surface of the straight groove, the dye delivered to the corresponding position can be separated by the dye guide groove, so that the dye can flow to the corresponding position accurately, which is conducive to the uniform delivery of the diluted dye, and further helps to improve the uniformity of the dye concentration in the printing and dyeing frame.

[0012] Preferably, the driving assembly includes an open frame, a limit frame, a threaded rod, a sliding seat and a slot, the open frame is fitted on the side wall of the printing and dyeing frame, the limit frame is installed on the bottom of the open frame, the threaded rod is rotatably connected to the limit frame, and the threaded rod extends to the outside of the limit frame, the threaded rods in the two driving assemblies are transmission connected, the sliding seat is slidably arranged on the inner side of the open frame, and the sliding seat is threadedly connected to the threaded rod, and the slot is opened at the top of the sliding seat.

[0013] In the above scheme, since the diluted dye liquid adding components are located in opposite directions in the initial state of the two driving components, the threaded rods in the two driving components rotate in opposite directions. When the threaded rods are rotated at a uniform speed by the driving motor, the diluted dye liquid adding components can be driven to move horizontally at a uniform speed along the outer wall of the printing and dyeing frame, which is conducive to achieving uniformity of dye liquid delivery.

[0014] Preferably, the diluted dye liquid adding component includes a dye liquid cylinder, an inner screw, a connecting gear, an inner slide plate, an insert, a silicone sheet and a sealing plug, the dye liquid cylinder is fitted on the surface of the sliding seat, the inner screw is rotatably connected to the dye liquid cylinder, and the inner screw extends to the outside of the dye liquid cylinder at one end close to the horizontal rack, the connecting gear is sleeved on the end of the inner screw, and the connecting gear is meshed with the horizontal rack, the inner slide plate is threadedly connected to the inner screw, and the inner slide plate is slidingly and sealingly fitted on the inner circumference of the dye liquid cylinder, the insert block is fixed to the bottom of the dye liquid cylinder, the silicone sheet is fitted on the side of the dye liquid cylinder away from the connecting gear, and a circular hole is opened on the side wall of the silicone sheet, and the sealing plug is sealingly inserted at the top of the dye liquid cylinder.

[0015] In the above scheme, when the dye liquid cylinder moves horizontally under the action of the driving component, the connecting gear will drive the inner screw to rotate at a uniform speed under the meshing action of the connecting gear and the horizontal rack, thereby causing the inner slide plate to move horizontally along the inner wall of the dye liquid cylinder, thereby squeezing out the dye liquid with increased volume after dilution at a uniform speed, achieving uniform delivery of the diluted dye liquid, which is beneficial to ensure the uniformity of the position of the dye liquid delivered in the printing and dyeing frame.

[0016] Preferably, the gathering component includes a rotating column, a first spiral blade, a circular plate, a connecting block and a second spiral blade. The two rotating columns are rotatably connected to the printing and dyeing frame, and the ends of the rotating columns extend to the outside of the printing and dyeing frame. The first spiral blade and the second spiral blade are respectively mounted on the outer circumferences of the two rotating columns, the circular plates are respectively fixed to the ends of the two rotating columns, the connecting block is rotatably installed between the two circular plates, and the connection position of the connecting block and the circular plate is not on the line connecting the centers of the two circular plates. The bottom of the connecting block is rotatably connected to the edge of the spoiler, and the rotation direction of the first spiral blade is opposite to that of the second spiral blade.

[0017] In the above scheme, when the driving motor drives the rotating column to rotate, the first spiral blade and the second spiral blade with opposite rotation directions drive the dye liquid close to the inner wall of the printing and dyeing frame to flow toward the axis side of the printing and dyeing frame, and under the action of the connecting block eccentrically connected to the circular plate, when the circular plate rotates at a uniform speed with the rotating column, the spoiler located at the lower end of the rotating column is driven by the connecting plate to move up and down continuously, which can achieve uniform stirring and mixing of the entire dye liquid in the printing and dyeing frame while avoiding dye precipitation in the bottom dye liquid in the printing and dyeing frame, thereby further improving the uniformity of the overall concentration of the dye liquid in the printing and dyeing frame.

[0018] Preferably, the reflux assembly includes a reflux frame, a reflux vane, a first bevel gear and a second bevel gear. The reflux frame is installed between two flow slots on the same side of the printing and dyeing frame. The reflux vane is rotatably arranged in the reflux frame. The first bevel gear is sleeved on the outer periphery of the reflux vane shaft. The second bevel gear is meshed with the first bevel gear, and the second bevel gear is sleeved on one of the ends of the rotating column.

[0019] In the above scheme, when the driving motor is started, the reflux vanes rotate synchronously, and then combined with the functions of the gathering component and the spoiler, the dye liquid is driven to flow in one direction, and the circulation flow of the dye liquid can be realized, thereby greatly improving the mixing effect of the dye liquid in the printing and dyeing frame, making the dye liquid concentration in various places in the printing and dyeing frame tend to be consistent, effectively ensuring the dyeing quality of the outer protective cover of the solid color sofa.

[0020] Preferably, the two flow slots located on the same side of the printing and dyeing frame are not on the same horizontal plane, and the flow slot close to the end of the printing and dyeing frame is lower than the flow slot on the other side.

[0021] In the above scheme, since the heights of the flow slots on the same side of the printing and dyeing frame are inconsistent, in the process of driving the dye liquid to circulate, the reflux height difference can be utilized to enable the bottom layer of dye liquid to not only participate in the circulation flow, but also be fully mixed with the upper layer of dye liquid, further improving the uniformity of dye liquid mixing.

[0022] Preferably, the silica gel sheet is arranged on the upper side of the end of the dye liquid cylinder, and both sides of the dye liquid cylinder are arranged to be flat.

[0023] In the above scheme, the diameter of the dye liquid outlet can be set smaller under the action of the silicone sheet. When the dye liquid is squeezed, the silicone sheet is deformed and the dye liquid outlet is expanded, which can fully ensure the delivery rate of the dye liquid.

[0024] Preferably, the circulation slot is configured with an arc surface on one side close to the interior of the printing and dyeing frame.

[0025] In the above scheme, under the action of the arc surface, it is convenient to guide the dyeing liquid in the printing and dyeing frame into the reflux frame to participate in the circulation flow, thereby ensuring that the dyeing liquid can circulate smoothly.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. By setting the diluted dye liquid adding component, driving component and horizontal rack, the diluted dye liquid adding component is driven to move horizontally along the outer wall of the printing and dyeing frame at a uniform speed during the starting process of the driving component, and the diluted dye liquid is evenly squeezed into the printing and dyeing frame during the uniform movement, thereby ensuring the uniformity of dye liquid delivery, and then effectively ensuring the dyeing uniformity of the outer protective cover of the plain sofa, thereby improving the printing and dyeing quality of the outer protective cover of the plain sofa.

[0028] 2. Through the gathering component and spoiler, when the printing and dyeing operation is carried out and the diluted dye is added, the gathering component drives the dye at the edge of the printing and dyeing frame to flow toward the axis side of the printing and dyeing frame, and drives one end of the spoiler to move up and down continuously, which can not only make the added dye fully mixed with the original dye, but also effectively avoid the precipitation phenomenon in the lower layer of the dye and cause the overall dye concentration to be uneven, thereby fully ensuring the uniformity of the dye, thereby effectively improving the printing and dyeing quality of the outer protective cover of the solid color sofa.

[0029] 3. By setting the reflux component, gathering component and spoiler, when the gathering component drives one end of the spoiler to move up and down continuously and the dye liquid flows in one direction, the reflux component can guide the dye liquid to the opposite side of the dye liquid flow direction, so that the dye liquid can be continuously circulated, further ensuring the uniformity of the overall dye liquid in the printing and dyeing frame, ensuring the uniformity of the plain color sofa outer protective cover after printing and dyeing, and fully improving the printing and dyeing quality of the plain color sofa outer protective cover.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0040] See also Figures 1 to 8 The present invention provides a printing and dyeing equipment for processing textile chemical fiber cloth, and the technical scheme is as follows:

[0041] A printing and dyeing device for processing textile chemical fiber cloth comprises a printing and dyeing frame 1, a traction roller 2, a partition 3, a rotating roller 12, and a driving motor 14. Two traction rollers 2 are respectively installed at the top ends of the printing and dyeing frame 1. Due to guiding the outer protective cover of the sofa to enter and exit the printing and dyeing frame 1, the partition 3 is installed between the inner walls of the printing and dyeing frame 1. The partition 3 forms two spaces inside the printing and dyeing frame 1, wherein the larger space is used for coloring operation, and the space on the other side is used for washing operation to realize continuous impregnation operation. The rotating roller 12 is rotatably installed between the inner walls of the printing and dyeing frame 1 at different heights. The driving motor 14 is installed on one side outer wall of the printing and dyeing frame 1, as the dynamic part of the printing and dyeing device. The printing and dyeing frame 1 is provided with a plurality of flow slots 4, a driving assembly 5, a horizontal rack 6, a diluted dye liquid adding assembly 7, a straight slot 8, a gathering assembly 10, a spoiler 11 and a reflux assembly 13. The four flow slots 4 are arranged on both sides of the printing and dyeing frame 1 in pairs, and the two driving assemblies 5 are respectively arranged on both sides of the printing and dyeing frame 1, and the two driving assemblies 5 are connected by transmission, and the two horizontal racks 6 are respectively installed on the inner sides of the two driving assemblies 5. The diluted dye liquid adding assembly 7 is plugged into the driving assembly 5. After the driving assembly 5 is started, the diluted dye liquid adding assembly 7 is driven to move horizontally at a uniform speed, and the diluted dye liquid adding assembly 7 is connected to the horizontal rack 6. Since the diluted dye liquid adding assembly 7 is in the driving assembly 5, the diluted dye liquid adding assembly 7 is connected to the horizontal rack 6. The horizontal rack 6 does not move under the action of the driving component 5, and the diluted dye liquid adding component 7 can be controlled to extrude the diluted dye liquid at a uniform speed by means of the horizontal rack 6, thereby realizing the uniform speed of sequentially placing the dye liquid in various places in the printing and dyeing frame 1; the straight groove 8 is arranged on both sides of the printing and dyeing frame 1, and the straight groove 8 is located on the inner side of the driving component 5, and the dye liquid squeezed out by the diluted dye liquid adding component 7 passes through the straight groove 8 and falls into the printing and dyeing frame 1, the gathering components 10 are installed on the inner side of the printing and dyeing frame 1 at equal intervals, and the adjacent gathering components 10 are transmission connected, the spoiler 11 is hinged to the inner bottom surface of the printing and dyeing frame 1, and the spoiler 11 is rotatably connected to the gathering component 10, and the number of spoilers 11 is the same as the number of gathering components 10 The amount is consistent. When the gathering component 10 is started, the corresponding spoiler 11 is driven to move up and down continuously at one end connected to the gathering component 10; the reflux component 13 is installed between the two flow slots 4 on the same side of the printing and dyeing frame 1, and one of the gathering components 10 is simultaneously connected to the driving component 5 and the reflux component 13. The driving motor 14 is connected to one of the gathering components 10. The driving motor 14 first drives the gathering component 10 connected thereto to start, and the adjacent gathering components 10 are synchronously rotated in the same direction through the chain and sprocket. Then the gathering component 10 at the edge drives a driving component 5 and the reflux component 13 to rotate, and the two driving components 5 are synchronously driven through the chain and sprocket.

[0042] When the driving motor 14 drives the gathering component 10 to rotate, the driving component 5 and the reflux component 13 are started synchronously. When the driving component 5 drives the diluted dye liquid adding component 7 to move linearly, the diluted dye liquid adding component 7 injects dye into the printing and dyeing frame 1 at a uniform speed. When the gathering component 10 rotates, the dye liquid is gathered toward the axis side of the printing and dyeing frame 1, and the gathering component 10 drives the spoiler 11 to swing up and down to push the bottom dye liquid toward the side of the partition 3. At the same time, the reflux component 13 drives the dye liquid at the partition 3 to flow toward the inner end of the printing and dyeing frame 1. When the components in the above components need to pass through the printing and dyeing frame 1, they are sealed with the printing and dyeing frame 1. A sealed bearing is provided at the rotating part, and a sealing ring is provided at the non-rotating part to ensure that the dye does not leak from the printing and dyeing frame 1.

[0043] Reference Figure 2 As an embodiment of the present invention, specifically, the bottom surface of the straight groove 8 is inclined, and a plurality of dye guide grooves 9 are arranged on the bottom surface of the straight groove 8 to fit each other. After the dye drops on the bottom surface of the straight groove 8, it can flow accurately to the corresponding position in the dye frame.

[0044] Reference Figure 3 and Figure 4 As an embodiment of the present invention, specifically, the driving assembly 5 includes an open frame 51, a limit frame 52, a threaded rod 53, a sliding seat 54 and a slot 55. The open frame 51 is fitted on the side wall of the printing and dyeing frame 1, the limit frame 52 is installed at the bottom of the open frame 51, the threaded rod 53 is rotatably connected with the limit frame 52, and the threaded rod 53 extends to the outside of the limit frame 52. The threaded rods 53 in the two driving assemblies 5 are transmission-connected, the sliding seat 54 is slidably arranged on the inner side of the open frame 51, and the sliding seat 54 is threadedly connected with the threaded rod 53, and the slot 55 The threaded rods 53 in the two driving components 5 are opened on the top of the sliding seat 54, and the rotation directions are opposite. Therefore, in the initial state, the diluted dye liquid adding component 7 is located at the opposite end of the corresponding open frame 51, so that the diluted dye liquid can be added to the printing and dyeing frame 1 from two directions, and the delivery accuracy of the dye liquid can be improved by reducing the delivery amount of the diluted dye liquid at a local position in the printing and dyeing frame 1; when the threaded rod 53 rotates, the sliding seat 54 moves at a uniform speed in a straight line along the inner wall of the limit frame 52, thereby driving the diluted dye liquid adding component 7 to move horizontally and linearly at a uniform speed.

[0045] Reference Figure 5 and Figure 6As an embodiment of the present invention, specifically, the diluted dye adding component 7 includes a dye cylinder 71, an inner screw rod 72, a connecting gear 73, an inner slide plate 74, an insert 75, a silicone sheet 76 and a sealing plug 77. The dye cylinder 71 is attached to the surface of the sliding seat 54, the inner screw rod 72 is rotatably connected to the dye cylinder 71, and the inner screw rod 72 extends to the outside of the dye cylinder 71 near the horizontal rack 6. The connecting gear 73 is sleeved on the end of the inner screw rod 72, and the connecting gear 73 is meshed with the horizontal rack 6. The inner slide plate 74 is threadedly connected to the inner screw rod 72, and the inner slide plate 74 is slidingly sealed and attached to the inner periphery of the dye cylinder 71. The insert block 75 is fixed to the bottom of the dye cylinder 71, and the silicone sheet 76 is attached to the side of the dye cylinder 71 away from the connecting gear 73, and the side wall of the silicone sheet 76 is opened There is a circular hole, and the sealing plug 77 is sealed and inserted in the top of the dye cylinder 71. The silicone sheet 76 is arranged on the upper side of the end of the dye cylinder 71. Both sides of the dye cylinder 71 are arranged to be flat. Since both sides of the dye cylinder 71 are flat, the inner slide plate 74 cannot rotate with the inner screw rod 72. When the inner screw rod 72 rotates, the inner slide plate 74 can only move horizontally along the inner wall of the dye cylinder 71 to squeeze the dye. In the process of the dye cylinder 71 moving horizontally and linearly at a uniform speed with the sliding seat 54, the connecting gear 73 and the horizontal rack 6 rotate relative to each other, thereby driving the inner screw rod 72 to rotate. Under the action of the rotating inner screw rod 72, the inner slide plate 74 moves along the inner wall of the dye cylinder 71 toward the side of the silicone sheet 76, thereby uniformly dropping the dye from the dye outlet of the stretched silicone sheet 76 to the corresponding position in the printing and dyeing frame 1.

[0046] Reference Figure 1 and Figure 7As an embodiment of the present invention, specifically, the gathering component 10 includes a rotating column 101, a first spiral leaf 102, a circular plate 103, a connecting block 104 and a second spiral leaf 105. The two rotating columns 101 are rotatably connected to the printing and dyeing frame 1, and the ends of the rotating columns 101 extend to the outside of the printing and dyeing frame 1. The first spiral leaf 102 and the second spiral leaf 105 are respectively sleeved on the outer circumference of the two rotating columns 101, and the circular plates 103 are respectively fixed to the ends of the two rotating columns 101. A shaft body is fixed between the circular plates 103, and the circular plates 103 are synchronously rotated by the shaft body. The connecting block 104 is rotatably installed between the two circular plates 103, and the connecting block 104 is rotatably connected to the outer circumference of the shaft body. The connection position of the connecting block 104 and the circular plate 103 is not on the line connecting the centers of the two circular plates 103. The connecting block The bottom of 104 is rotatably connected to the edge of the spoiler 11, and the rotation direction of the first spiral leaf 102 is opposite to that of the second spiral leaf 105. The two rotating columns 101 in the same gathering component 10 rotate in the same direction. Since the rotation directions of the first spiral leaf 102 and the second spiral leaf 105 are opposite, the dye liquid in the printing and dyeing frame 1 can be driven to flow relatively. When the circular plate 103 rotates synchronously with the rotating column 101, since the connecting block 104 is eccentrically connected to the circular plate 103, it will drive the connecting block 104 to move up and down continuously, and the angle changes adaptively, so that the end of the spoiler 11 located below the rotating column 101 moves up and down continuously, fully squeezing the bottom dye liquid, and can push the dye liquid to flow to the side of the partition 3, effectively avoiding the precipitation of the dye in the bottom dye liquid, thereby ensuring the uniformity of the dye liquid in the printing and dyeing frame 1.

[0047] Reference Figure 8 As an embodiment of the present invention, specifically, the reflux assembly 13 includes a reflux frame 131, a reflux vane 132, a first bevel gear 133 and a second bevel gear 134. The reflux frame 131 is installed between the two flow slots 4 on the same side of the printing and dyeing frame 1. The reflux vane 132 is rotatably arranged in the reflux frame 131. The first bevel gear 133 is sleeved on the outer periphery of the rotating shaft of the reflux vane 132. The second bevel gear 134 is meshed with the first bevel gear 133, and the second bevel gear 134 is sleeved on one end of the rotating column 101. When the rotating column 101 rotates, the second bevel gear 134 rotates therewith, and then drives the reflux vane 132 to rotate through the meshing with the first bevel gear 133, so that the dye liquid in the reflux frame 131 flows from the side close to the partition 3 to the side away from the partition 3, thereby realizing the circulation of the dye liquid.

[0048] Reference Figure 1 and Figure 2As an embodiment of the present invention, specifically, the two flow grooves 4 located on the same side of the printing and dyeing frame 1 are not on the same horizontal plane, the flow groove 4 close to the end of the printing and dyeing frame 1 is lower than the flow groove 4 on the other side, and the flow groove 4 is close to the inner side of the printing and dyeing frame 1. A curved surface is constructed, and there is a height difference in the circulation process of the dye liquid. The bottom layer of dye liquid not only participates in the circulation flow, but also is fully mixed with the upper layer of dye liquid, and the uniformity of the dye liquid mixing is further improved. In addition, the curved surface can guide the dye liquid in the printing and dyeing frame 1 to enter the reflux frame 131 to participate in the circulation flow, and the dye liquid can circulate smoothly.

[0049] Working principle: preheat the dyeing liquid in the printing and dyeing frame 1 to a dyeing temperature suitable for the chemical fiber cloth, then overlap the outer protective cover of the sofa on the surface of the traction roller 2 at one end away from the partition 3, and then pass through the rotating roller 12 in sequence and enter the washing space on the side of the partition 3 away from the spoiler 11. Finally, the outer protective cover of the sofa is placed on the surface of the traction roller 2 at the other end of the partition 3, and the traction device pulls the outer protective cover of the sofa to move at a uniform speed. The outer protective cover of the sofa that is not fully dyed at the front end of the traction is cut off after drying;

[0050] As the dye in the dye solution adheres to the outer protective cover of the sofa, the dye solution concentration in the printing and dyeing frame 1 decreases. When it is necessary to add high-concentration dye solution into the printing and dyeing frame 1 to increase the dye solution concentration in the printing and dyeing frame 1 to the set printing and dyeing concentration, the high-concentration dye solution is diluted in proportion and loaded into the dye solution cylinder 71. The driving motor 14 drives the gathering component 10 close to the side of the partition 3 to rotate, and the adjacent gathering components 10 are connected to each other to achieve synchronous rotation. The gathering component 10 away from the side of the partition 3 drives the two driving components 5 as well as the gathering component 10 and the reflux component 13 to start. The driving component 5 drives the diluted dye solution adding component 7 to move horizontally at a uniform speed along the outer wall of the printing and dyeing frame 1, and in the process of uniform speed The diluted dye liquid is squeezed out into the printing and dyeing frame 1 at a constant speed, thereby achieving uniform delivery of the dye liquid; and the gathering component 10 drives the entire dye liquid in the printing and dyeing frame 1 to move from the side close to the reflux component 13 to the side of the central axis of the printing and dyeing frame 1, and at the same time drives one end of the spoiler 11 to continuously move up and down, so that the delivered dye liquid is further fully mixed with the original dye liquid, and combined with the functions of the reflux component 13 and the spoiler 11, the dye liquid is circulated in the printing and dyeing frame 1, and the bottom dye liquid also participates in the circulation flow to avoid the precipitation of the dye, thereby fully ensuring the uniformity of the dye liquid in the printing and dyeing frame 1, and then effectively ensuring the dyeing uniformity and dyeing quality of the outer protective cover of the plain sofa;

[0051] Specifically, the driving motor 14 is connected to one of the gathering components 10, and the driving motor 14 first drives one gathering component 10 to start, and the adjacent gathering components 10 rotate synchronously in the same direction through the chain and the sprocket, and then the gathering component 10 at the edge drives a driving component 5 and a reflux component 13 to start, and the two driving components 5 realize synchronous transmission through the chain and the sprocket;

[0052] When the threaded rod 53 rotates, the sliding seat 54 moves linearly and at a uniform speed in contact with the inner wall of the limit frame 52, driving the dye liquid cylinder 71 to move horizontally and linearly at a uniform speed, and the connecting gear 73 moves synchronously with the sliding seat 54, and rotates relatively with the horizontal rack 6, and then the connecting gear 73 drives the inner screw rod 72 to rotate, and the inner slide plate 74 moves along the inner wall of the dye liquid cylinder 71 toward the side of the silicone sheet 76 under the action of the rotating inner screw rod 72, and uniformly releases the dye liquid from the dye liquid outlet of the opened silicone sheet 76 to the corresponding position in the printing and dyeing frame 1;

[0053] At the same time, a plurality of rotating columns 101 rotate in the same direction. Since the first spiral blade 102 and the second spiral blade 105 rotate in opposite directions, the dye liquid in the printing and dyeing frame 1 can be driven to flow relatively and gather toward the central axis side of the printing and dyeing frame 1. Since the connecting block 104 is eccentrically connected to the circular plate 103, the circular plate 103 drives the connecting block 104 to move up and down continuously. The spoiler 11 is located at one end below the rotating column 101 and moves up and down continuously, fully squeezing the bottom dye liquid and pushing the dye liquid to flow toward the side of the partition 3 to prevent the dye in the bottom dye liquid from precipitating.

[0054] In addition, when the rotating column 101 rotates, the second bevel gear 134 rotates therewith, and the second bevel gear 134 drives the meshing first bevel gear 133 to rotate, and then the reflux vane 132 rotates, so that the dye liquid in the reflux frame 131 flows from the side close to the partition 3 to the side away from the partition 3, realizing the circulation of the dye liquid, thereby making the dye liquid concentration in the printing and dyeing frame 1 continuously at the set concentration value to perform the dyeing operation on the outer protective cover of the sofa.

[0055] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
