Description

Technical Field

[0001] This utility model relates to the field of printing and dyeing technology, specifically a blanket printing and dyeing device. Background Technology

[0002] Blankets, as common bedding items, are woven from coarse fibers such as wool and synthetic blends. They combine lightweight and warmth, and are typically thinner and fluffier than traditional cotton quilts. Thanks to their unique fiber structure, these textiles not only possess excellent insulation properties but also exhibit practical characteristics such as wear resistance, durability, a smooth surface, soft touch, and strong resilience. Furthermore, diverse weaving techniques give them the advantages of being lightweight, easy to store, and aesthetically pleasing. It is worth noting that the visual appeal of blankets directly influences consumers' purchasing decisions; therefore, the dyeing and printing process is crucial in actual production. Precise pattern design and color matching can both conceal imperfections that may occur during the weaving process and give the product a fashionable aesthetic, thereby increasing sales.

[0003] When dyeing and printing blankets, the entire blanket needs to be immersed in dye to ensure the pigment fully penetrates the fabric. However, during this process, the blanket is often immersed in the dye while stationary. This can lead to insufficient dye penetration due to surface tension or uneven fiber arrangement, resulting in color spots, color differences, or floating color. While the operator may move the blanket briefly within the dye, this movement is inconsistent, still causing color spots, color differences, or floating color. Furthermore, for a large number of blankets, the operator must move them one by one, leading to excessive labor consumption and reduced dyeing and printing efficiency. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a blanket printing and dyeing device to solve the current problem that when printing and dyeing blankets, the entire blanket needs to be immersed in dye to ensure that the pigment can fully penetrate into the blanket for dyeing. However, in this process, the entire blanket is often immersed in the dye in a static state. As a result, the dye may not penetrate fully due to surface tension or uneven fiber arrangement, resulting in color spots, color differences, or floating color. At this time, the operator will also move the blanket, causing the blanket to shake briefly inside the dye. This operation not only makes the shaking of the blanket itself inconsistent, but also still results in color spots, color differences, or floating color. Moreover, for a large number of blankets, the operator can only move them one by one, resulting in excessive labor consumption in the overall dyeing process and affecting the efficiency of blanket printing and dyeing.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a blanket printing and dyeing device is designed, including a processing frame, a drain pipe is connected to the bottom left side of the processing frame, and rotating frames are rotatably installed on both sides inside the processing frame, and a suspension mechanism is detachably installed between the inner sides of the two sets of rotating frames.

[0006] A fixed frame is fixedly installed on the top of the outer side of the processing frame, and a rotating mechanism is provided inside the fixed frame, and the rotating mechanism and the rotating frame are connected in a transmission manner.

[0007] A transmission frame is fixedly installed on the outer wall of the fixed frame. A reciprocating push-pull mechanism is provided inside the transmission frame, and the reciprocating push-pull mechanism and the rotation mechanism are connected in a transmission connection.

[0008] Preferably, the reciprocating push-pull mechanism includes a transmission cam and a connecting plate. A rotating rod is rotatably mounted on the inner middle of the transmission frame via a bearing. A rotating motor is fixedly mounted on the middle of the side of the transmission frame near the processing frame. The side of the transmission shaft of the rotating motor is fixedly connected to the side of the rotating rod via a coupling. The transmission cam is fixedly sleeved on the side of the rotating rod. A second fixed rod is fixedly mounted on the middle of the side of the transmission cam. The connecting plate is rotatably sleeved on the outer side of the second fixed rod via a bearing. A first fixed rod is rotatably inserted through the middle of the other side of the connecting plate via a bearing. Limiting grooves are provided at the bottom of the side of the fixed frame and the middle of the side of the transmission frame. A push plate is slidably mounted through the limiting groove. The outer sides of the first fixed rod are respectively fixedly inserted into the inner side of the push plate.

[0009] Preferably, the reciprocating push-pull mechanism includes a transmission rack and a follower gear. A transmission rod is rotatably mounted inside the fixed frame through bearings at equal intervals, and the side end of the transmission rod is fixedly connected to the outer wall of the rotating frame. A transmission rack is movably mounted at the bottom of the inside of the processing frame. A follower gear is fixedly sleeved on the outside of each rotating rod, and the top and bottom of the transmission rack mesh with each other.

[0010] Preferably, the suspension mechanism includes a support rod and a sleeve roller. A connecting block is movably inserted inside each of the rotating frames. A support rod is fixedly installed between the sides of every two sets of connecting blocks. An installation frame is fixedly sleeved at both ends of the outer side of each support rod. A support plate is vertically fixedly installed at the bottom of each installation frame. A sleeve roller is rotatably installed on the side of each support plate.

[0011] Preferably, a fixing bolt is slidably inserted between the interior of each of the rotating frames and the connecting block, and a fixing nut is threaded onto the top of the side of each fixing bolt.

[0012] Preferably, a sliding plate is fixedly installed at one end of the transmission rack near the transmission frame, and guide sliders are fixedly installed laterally at both ends of the sliding plate. A connecting frame is fixedly installed at the end of the push plate away from the connecting plate, and the sliding plate is slidably inserted into the connecting frame. Guide grooves are laterally opened on both sides of the connecting frame, and guide sliders are slidably inserted into the guide grooves. A hand lever is fixedly installed laterally at the end of the transmission rack away from the transmission frame. A movable groove is opened at the bottom of the side of the fixed frame away from the transmission frame. A transparent observation plate is fixedly embedded in the side of the fixed frame. An insertion groove is opened in the middle of the side of the connecting frame. A connecting screw hole is opened in the middle of the side of the sliding plate. A connecting bolt is slidably inserted through the middle of the transparent observation plate, and the side end of the connecting bolt is slidably inserted into the insertion groove. The top end of the side of the connecting bolt is screwed into the connecting screw hole by a thread.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model features a rotating rod inside a transmission frame and a transmission cam sleeved on the outside of the rotating rod. The two ends of a connecting plate are connected to the transmission cam and a push plate via a first and second fixed rod. When the rotating motor drives the rotating rod and transmission cam to rotate, the two ends of the connecting plate can rotate relative to each other outside the first and second fixed rods. This means the two ends of the push plate can rotate relative to each other on the sides of the transmission cam and the push plate. As the transmission cam rotates, the push plate converts the rotational force of the transmission cam into a reciprocating pushing and pulling force on the push plate, allowing the push plate to move left and right within the limiting groove. After a rightward reciprocating translation, the transmission rack can be synchronously driven to reciprocate left and right at the bottom of the fixed frame. Combined with the meshing transmission of the transmission rack and follower gear, the follower gear and rotating rod can be driven to rotate clockwise and counterclockwise alternately. This causes the rotating frame to swing left and right synchronously inside the processing frame. This allows multiple sets of rotating frames to cause the blankets suspended on their sides to swing automatically in the dye contained inside the processing frame. This makes it easier for dye molecules to penetrate the fiber gaps, promotes the flow of dye liquor between fibers, reduces local concentration differences, and simultaneously improves the printing and dyeing quality of multiple sets of products, while reducing the labor consumption required for manual operation.

[0015] 2. This utility model features a sliding plate and a connecting frame on the side of the transmission rack and the side of the push plate, respectively. The sliding plate is slidably installed inside the connecting frame. After the connecting bolt passes through the connecting frame and is screwed into the sliding plate, the synchronous transmission between the connecting frame and the sliding plate can be ensured. After the blanket printing is completed, the connecting bolt can be loosened and pulled out. The operator can then use the pull rod to move outward and continuously drive the transmission rack to move to the left. This allows the transmission rack to pass through the movable slot and move out of the fixed frame. At the same time, it continuously drives the follower gear and the rotating frame to rotate counterclockwise. This causes the connecting roller installed inside the rotating frame and the printed blanket outside it to rotate, lift, and move out of the processing frame synchronously. This facilitates the operator's observation of the blanket printing and the removal and replacement of the blanket. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0027] Example 1: A blanket printing and dyeing apparatus, see [link to example]. Figures 1 to 5 A drain pipe is connected to the bottom left side of the processing frame 1. Rotating frames 13 are rotatably installed on both sides inside the processing frame 1. A connecting block 14 is movably inserted into each rotating frame 13. A fixing bolt 5 is slidably inserted between each rotating frame 13 and the connecting block 14. A fixing nut 51 is screwed into the top of the side of each fixing bolt 5. A support rod 15 is fixedly installed between the sides of every two sets of connecting blocks 14. An installation frame 16 is fixedly sleeved at both ends of the outer side of each support rod 15. A support plate 17 is vertically fixedly installed at the bottom of each installation frame 16. A sleeve roller 18 is rotatably installed on the side of each support plate 17. The sleeve roller 18 has a corresponding slot on its side. When it is necessary to hang the blanket, the side end of the blanket can be locked into the slot, thereby realizing the hanging and fixing of the blanket.

[0028] When the blanket needs to be printed and dyed, according to the width of the blanket, select the appropriate connecting rollers 18 with matching spacing. Then, snap the two ends of the blanket into the slots inside the connecting rollers 18, so that the blanket can be fixed between the two sets of connecting rollers 18. Then, push the support rod 15 and its side connecting block 14 into the rotating frame 13. According to the size of the blanket, select the appropriate number of single printing and dyeing cycles to ensure that the blankets will not collide with each other during rotation and reciprocating swing, thus affecting the printing and dyeing quality. This allows multiple sets of blankets and connecting rollers 18 to be placed vertically inside the processing frame 1. Pass the fixing bolts 5 through the rotating frame 13 and the connecting block 14, and then screw the fixing nuts 51 onto the side of the fixing bolts 5. Connect the rotating frame 13, the connecting block 14, and the connecting rollers 18 for transmission. Then, put the dye to be printed and dyed into the processing frame 1.

[0029] For details, see Figures 1 to 5A fixed frame 11 is fixedly installed on the top of the outer side of the processing frame 1. A transmission frame 12 is fixedly installed on the outer wall of the fixed frame 11. A rotating rod 2 is rotatably installed on the middle of the inner side of the transmission frame 12 via a bearing. A rotating motor 19 is fixedly installed on the middle of the side of the transmission frame 12 near the processing frame 1. The side of the transmission shaft of the rotating motor 19 is fixedly connected to the side of the rotating rod 2 via a coupling. A transmission cam 21 is fixedly sleeved on the side of the rotating rod 2. A second fixed rod 26 is fixedly installed on the middle of the side of the transmission cam 21. A connecting plate 22 is rotatably sleeved on the outer side of the second fixed rod 26 via a bearing. A first fixed rod 25 is rotatably inserted through the middle of the other side of the connecting plate 22 via a bearing. Limiting grooves 23 are provided on the bottom side of the fixed frame 11 and the middle of the side of the transmission frame 12. A push plate 24 is slidably installed through the limiting groove 23. The two outer sides of the first fixed rod 25 are fixedly inserted into the inside of the side of the push plate 24. The top of the side of the connecting plate 22 is rotatably sleeved into the inside of the end of the push plate 24 near the rotating rod 2.

[0030] After the dye is added and the blanket is vertically immersed in the dye, the rotating motor 19 is turned on by an external control switch, which provides a corresponding driving force to the rotating rod 2. This causes the rotating rod 2 and the transmission cam 21 to rotate synchronously inside the transmission frame 12. The two ends of the connecting plate 22 are connected to the transmission cam 21 and the push plate 24 respectively by the first fixed rod 25 and the second fixed rod 26. After the transmission cam 21 is driven to rotate, the two ends of the connecting plate 22 can rotate relative to each other outside the first fixed rod 25 and the second fixed rod 26. That is, the two ends of the push plate 24 can rotate relative to each other on the sides of the transmission cam 21 and the push plate 24 respectively. As the transmission cam 21 rotates continuously, the rotational force of the transmission cam 21 is converted into a reciprocating pushing and pulling force on the push plate 24, so that the push plate 24 can move back and forth inside the limiting slide groove 23.

[0031] Further, see Figures 1 to 5 Inside the fixed frame 11, a transmission rod 28 is rotatably mounted through bearings at equal intervals. The top edge of the transmission rod 28 is fixedly connected to the outer wall of the rotating frame 13 on the side of the processing frame 1 closest to the fixed frame 11. A corresponding crossbar is provided on the outer wall of the rotating frame 13 on the side of the processing frame 1 away from the fixed frame 11. The crossbar is rotatably inserted into the inner wall of the processing frame 1 through bearings. A transmission rack 27 is movably mounted at the bottom of the processing frame 1. A follower gear 29 is fixedly sleeved on the outer side of each rotating rod 2. The top and bottom of the transmission rack 27 mesh with each other.

[0032] When the push plate 24 is driven to move horizontally back and forth, the connecting bolt 33 connects the connecting frame 3 and the sliding plate 31, allowing the sliding plate 31 and the connecting frame 3 to be connected by transmission. This synchronously drives the transmission rack 27 to move horizontally back and forth inside the fixed frame 11. Combined with the meshing transmission of the transmission rack 27 and the follower gear 29, the follower gear 29 and the rotating rod 2 can be driven to rotate clockwise and counterclockwise alternately. This causes the rotating frame 13 to swing back and forth synchronously inside the processing frame 1. This allows multiple sets of rotating frames 13 to drive the blankets suspended on their sides to swing automatically back and forth in the dyes contained inside the processing frame 1, making it easier for dye molecules to penetrate the fiber gaps and improving the printing and dyeing quality of the blanket surface.

[0033] It is worth noting that, see Figures 1 to 5 A sliding plate 31 is fixedly installed at one end of the transmission rack 27 near the transmission frame 12. Guide sliders 36 are horizontally fixedly installed at both ends of the sliding plate 31. A connecting frame 3 is fixedly installed at the end of the push plate 24 away from the connecting plate 22, and the sliding plate 31 is slidably inserted into the interior of the connecting frame 3. Guide grooves 35 are horizontally opened on both sides of the interior of the connecting frame 3, and the guide sliders 36 are slidably inserted into the interior of the guide grooves 35. A hand lever 41 is horizontally fixedly installed at the end of the transmission rack 27 away from the transmission frame 12. A movable groove 4 is opened at the bottom of the side of the fixed frame 11 away from the transmission frame 12. The pull rod 41 is slidably inserted into the movable slot 4. The inner diameter of the movable slot 4 is larger than the size of the transmission rack 27 to ensure that the side end of the transmission rack 27 can pass through the movable slot 4 and move out from the inside of the fixed frame 11. A transparent observation plate 37 is fixedly embedded in the side of the fixed frame 11. A insertion slot 32 is opened in the middle of the side of the connecting frame 3. A connecting screw hole 34 is opened in the middle of the side of the sliding plate 31. A connecting bolt 33 is slidably inserted through the middle of the transparent observation plate 37, and the side end of the connecting bolt 33 is slidably inserted into the insertion slot 32. The top end of the side of the connecting bolt 33 is screwed into the connecting screw hole 34 by threads.

[0034] After the blanket printing and dyeing process, the connecting bolt 33 is tightened to remove it from the connecting frame 3 and the sliding plate 31. Then, the operator holds the hand lever 41 and continuously pulls it to the left. This causes the hand lever 41 to drive the transmission rack 27 to move synchronously to the right and pass through the movable groove 4. This allows the transmission rack 27 to continuously provide corresponding meshing driving force to the follower gear 29. The follower gear 29 then drives the rotating frame 13 and the sleeve roller 18 to rotate counterclockwise. This causes the blanket, which was originally vertically immersed in the dye, to rotate counterclockwise and be lifted out of the processing frame 1. Inside, it is convenient for the operator to observe the quality of the blanket printing and dyeing, and to disassemble and replace the printed blanket. After that, the operator continuously pushes the hand lever 41 to the right, so that the transmission rack 27 can drive the sliding plate 31 to move to the right in sync. The operator can then observe the position of the sliding plate 31 through the transparent observation plate 37 until the guide slider 36 on the side of the sliding plate 31 is aligned with the guide groove 35. After the sliding plate 31 is completely moved into the connecting frame 3, the connecting bolt 33 is passed through the transparent observation plate 37 to connect the sliding plate 31 and the connecting frame 3 for transmission, which is convenient for subsequent transmission.
