Technical Field

[0001] This utility model relates to the field of printing equipment, and more specifically, it relates to a dye-free printing equipment. Background Technology

[0002] Printing is a process of applying patterns to textiles using dyes or pigments. During fabric processing, printing equipment is needed to print patterns on the fabric surface. Currently, printing dye is usually applied to the surface of a printing roller, and the printing roller is used to print on the fabric surface. However, existing printing equipment usually only has printing rollers with one type of pattern. When different patterns need to be printed, printing rollers with different patterns are required. In this case, the printing roller needs to be disassembled and replaced with a printing roller with a different pattern, which is inconvenient.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dye-free printing device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dye-free printing device, comprising a box body and a fabric inlet and an fabric outlet on both sides of the box body. A rotating frame is rotatably connected inside the box body between the fabric inlet and the fabric outlet. Multiple printing rollers with different patterns are rotatably mounted on the rotating frame. The multiple printing rollers are arranged in a circular array on the rotating frame. An imprinting gap is formed between the printing rollers and the rotating frame for the fabric to pass through. An applicator roller is rotatably connected inside the box body. The applicator roller is in contact with the outer peripheral wall of the printing roller located directly below the rotating frame, and the axial direction of the applicator roller is relatively parallel to the axial direction of the printing roller. A dye frame containing dye is installed inside the box body. The dye frame is located directly below the applicator roller. The bottom of the applicator roller is in contact with the dye in the dye frame. The imprinting gap is located above the applicator roller.

[0006] Preferably, the rotating frame includes a rotating rod and multiple mounting frames. The mounting frames have a U-shaped cross-section, and the openings of the mounting frames are positioned away from the rotating rod. The rotating rod is rotatably connected inside the housing. The mounting frames are fixedly connected to the outer peripheral wall of the rotating rod via connecting plates. The number and position of the mounting frames correspond one-to-one with those of the printing rollers. The printing rollers are mounted inside the mounting frames by a motor. The printing gap is formed between the printing rollers and the mounting frames.

[0007] Preferably, the top of the housing has an opening, the output end of the motor passes through the side wall of the mounting frame, and the output end of the motor is fixedly installed to one end of the printing roller by a connector. The inner wall of the mounting frame is provided with clamping components for clamping both ends of the printing roller.

[0008] Preferably, the connecting component includes a flange, which is fixedly connected to the output end of the motor and the outer peripheral wall of one end of the printing roller, respectively. The motor and the flange on the printing roller are respectively arranged correspondingly, and the corresponding flanges are fixedly installed by bolts.

[0009] Preferably, the clamping assembly includes a clamping block and a clamping plate rotatably connected to the clamping block. One side of the clamping block is fixedly connected to the inner wall of the mounting frame. The clamping block and the clamping plate are both provided with grooves for accommodating the end of the printing roller on their respective sides. The clamping plate and the clamping block are fixedly installed by screws.

[0010] Preferably, a dye tank and a water pump are fixedly connected to the outer side wall of the box, an infusion pipe for conveying dye to the dye frame is fixedly connected to the dye tank, and a suction pipe is fixedly connected to the water pump. One end of the infusion pipe and the suction pipe respectively penetrates the outer side wall of the box and is located inside the dye frame.

[0011] In summary, this utility model has the following beneficial effects: This solution involves a rotating frame mounted inside the housing, with multiple printing rollers of different patterns arranged in a circular array and rotatably mounted on the rotating frame. Simultaneously, the coating roller is brought into contact with a printing roller bearing one of the patterns located directly below the rotating frame. Fabric is fed into the housing through the inlet and passes through the printing gap between the printing roller and the rotating frame. At this point, rotating the coating roller ensures that the dye in the dye frame is evenly applied to its surface, and rotating the printing roller directly below the rotating frame further enhances the adhesion... The dye on the coating roller can be evenly adhered to the printing roller, and the printing roller located directly below the rotating frame will press the fabric in the printing gap. Because the printing gap is located above the coating roller, the dye will drip into the dye frame for collection. When it is necessary to change the pattern of the printing roller, the rotating frame is rotated and multiple printing rollers are rotated, so that one of the printing rollers with other patterns gradually rotates to the bottom of the rotating frame for use. Thus, by rotating the rotating frame, multiple printing rollers with different patterns can be rotated, which makes it easy to change the pattern of the printing roller to press the fabric into different patterns.

Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Example:

[0019] A dye-free washing printing device, such as Figures 1 to 4 As shown, the device includes a housing 1 and fabric inlets 2 and outlets 3 on both sides of the housing 1. A rotating frame 4 is rotatably connected inside the housing 1 between the inlets 2 and outlets 3. Multiple printing rollers 5 with different patterns are rotatably mounted on the rotating frame 4, arranged in a circular array. An impression gap 6 is formed between the printing rollers 5 and the rotating frame 4 for fabric to pass through. An applicator roller 7 is rotatably connected inside the housing 1 via a motor. The output end of the motor penetrates the side wall of the housing 1 and is welded to one end of the applicator roller 7. The applicator roller 7 is in contact with the outer peripheral wall of the printing roller 5 located directly below the rotating frame 4, and the axial direction of the applicator roller 7 is relatively parallel to the axial direction of the printing roller 5. A dye frame 8 containing dye is installed inside the housing 1. The top of the dye frame 8 is open, and the dye frame 8 is located directly below the applicator roller 7. The bottom of the applicator roller 7 contacts the dye in the dye frame 8. The impression gap 6 is located between the applicator roller 7 and the dye in the dye frame 8. Above, the rotating frame 4 includes a rotating rod 401 and multiple mounting frames 402. The axial direction of the rotating rod 401 is relatively parallel to the axial direction of the printing roller 5. The cross-section of the mounting frame 402 is arranged in a U-shape, and the opening of the mounting frame 402 is set away from the rotating rod 401. The rotating rod 401 is rotatably connected to the inside of the housing 1 by a second motor. The output end of the second motor passes through the side wall of the housing 1 and is welded to one end of the rotating rod 401. The mounting frame 402 is welded to the outer peripheral wall of the rotating rod 401 by a connecting plate 9. The two sides of the connecting plate 9 are respectively welded to the outer side wall of the mounting frame 402 and the outer peripheral wall of the rotating rod 401. The number and position of the mounting frames 402 correspond one-to-one with the printing rollers 5. The printing rollers 5 are rotatably installed inside the mounting frame 402 by a motor 10. The printing gap 6 is formed between the outer peripheral wall of the printing roller 5 and the inner wall of the mounting frame 402. The applicator roller 7 is used to fit against the outer peripheral wall of the printing roller 5 located directly below the rotating rod 401.

[0020] An opening is formed at the top of the housing 1. The output end of the motor 10 passes through the side wall of the mounting frame 402, and the output end of the motor 10 is fixedly installed to one end of the printing roller 5 via a connector. The motor 10 does not contact the inner side wall of the housing 1. A clamping assembly 12 for clamping both ends of the printing roller 5 is installed on the inner wall of the mounting frame 402. The connector includes a flange 11, which is welded to the output end of the motor 10 and the outer peripheral wall of one end of the printing roller 5, respectively. The flanges 11 on the motor 10 and the printing roller 5 are correspondingly arranged, and the corresponding flanges 11 are fixed by bolts. The flanges 11 on the motor 10 and the printing roller 5 are both located inside the mounting frame 402. The clamping assembly 12 includes a clamping block 121 and a clamping plate 122 rotatably connected to the clamping block 121 via a rotating shaft. One side of the clamping block 121 is welded to the inner wall of the mounting frame 402. The clamping block 121 and the clamping plate 122 are respectively provided with grooves 13 for accommodating the end of the printing roller 5 on their respective sides. The clamping plate 122 and the clamping block 121 are fixedly installed by screws. The clamping block 121 and the clamping plate 122 are respectively provided with threaded holes for connecting with the screws.

[0021] A dye box 14 and a water pump 16 are fixedly installed on the outer side wall of the box 1 by mounting bolts. The dye box 14 contains dye. A delivery pipe 15 for delivering dye to the dye frame 8 is attached to the dye box 14. A valve is installed on the delivery pipe 15. A suction pipe 17 is attached to the water pump 16. One end of the delivery pipe 15 and the suction pipe 17 pass through the outer side wall of the box 1 and is located inside the dye frame 8.

[0022] When the box 1 is in use, the applicator roller 7 is in contact with the outer peripheral wall of the patterned printing roller 5 located directly below the rotating rod 401. The user then feeds the fabric into the box 1 through the fabric inlet 2, allowing the fabric to pass through the printing gap 6 between the mounting frame 402 located directly below the rotating rod 401 and the printing roller 5. The user then starts the motor to drive the applicator roller 7 to rotate. At this time, the bottom of the applicator roller 7 contacts the dye in the dye frame 8. Because the applicator roller 7 is rotating, the dye can be evenly adhered to the outer peripheral wall of the applicator roller 7. Finally, the user starts the motor 10 located directly below the rotating rod 401, driving the printing roller 5... The printing roller 5 directly below rotates. At this time, bolts are respectively installed on the output end of the motor 10 and the flange 11 at one end of the printing roller 5. The end of the printing roller 5 is respectively attached to the inner wall of the groove 13 of the clamping block 121 and the clamping plate 122. The screws are respectively installed in the threaded holes on the clamping block 121 and the clamping plate 122. The end of the printing roller 5 is clamped by the clamping assembly 12, which improves the stability of the printing roller 5 in the mounting frame 402. Because the printing roller 5 located directly below the rotating rod 401 is in contact with the coating roller 7, the dye attached to the coating roller 7 can be evenly attached to the printing roller 5 located directly below the rotating rod 401 and then... The printing roller 5, located directly below the rotating rod 401, presses the fabric within the printing gap 6 between its corresponding mounting frame 402. Because the printing gap 6 between the mounting frame 402 and the printing roller 5, located directly below the rotating rod 401, is directly above the applicator roller 7, dye drips into the dye frame 8 for collection during fabric printing. The fabric is then passed through the printing gap 6 between the mounting frame 402 and the printing roller 5, and exited from the housing 1 through the fabric outlet 3, completing the printing process. When the pattern on the printing roller 5 needs to be changed, the rotating frame 4 is rotated, causing multiple printing rollers 5 to rotate. The starting motor drives the rotating rod 401 to rotate, causing the previously used printing roller 5 and its corresponding mounting frame 402 to gradually move away from directly below the rotating rod 401. This causes one of the unused printing rollers 5 with other patterns on its surface and its corresponding mounting frame 402 to gradually rotate to directly below the rotating rod 401 for use. This allows the fabric to pass through the printing gap 6 between the other printing rollers 5 and the mounting frame 402 located directly below the rotating rod 401. By rotating the rotating frame 4, multiple printing rollers 5 with different patterns can be rotated, allowing for quick and convenient replacement of the patterns on the printing rollers 5 to print different patterns on the fabric.

[0023] When the printing roller 5 located directly below the rotating rod 401 presses the fabric, one or more printing rollers 5 located above the rotating rod 401 are close to the opening at the top of the housing 1. The user then first removes the screw near the opening at the top of the housing 1 to disengage it from the threaded holes on the clamping block 121 and the clamping plate 122. Then, by rotating the clamping plate 122, the inner wall of the groove 13 on the clamping plate 122 is no longer in contact with the end of the printing roller 5. The user then removes the bolts to disengage it from the output end of the motor 10 and the end of the printing roller 5. The flange 11 on the top can remove the printing roller 5 near the top of the housing 1 from the mounting frame 402 and take it out from the opening at the top of the housing 1, so that the end of the printing roller 5 does not fit against the inner wall of the groove 13 of the clamping block 121. This allows the printing roller 5 located directly below the rotating rod 401 to be disassembled and replaced with a printing roller 5 with a different pattern when the printing roller 5 located directly below the rotating rod 401 is pressing, without affecting the printing efficiency of the printing roller 5 located directly below the rotating rod 401 on the fabric.

[0024] One end of the infusion tube 15 and the suction tube 17 are both located inside the dye frame 8. By opening the valve, the dye in the dye box 14 is transported to the dye frame 8 through the infusion tube 15. Then the valve is closed, and the coating roller 7 is rotated so that the surface can be coated with dye. When the dye in the dye frame 8 needs to be replaced, the water pump 16 is started and the suction tube 17 is used to extract the dye from the dye frame 8 for replacement with new dye.
