Description

Technical Field

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

[0002] Transfer printing paper is a new type of industrial paper, mainly used in textile printing processes. Various patterns, designs, and colors are first printed onto transfer paper using disperse dyes with sublimation properties. Then, the transfer paper with the printed patterns comes into close contact with the fabric. Under controlled temperature, pressure, and time, the dye is transferred from the printing paper to the fabric and then diffuses into the fabric, thus achieving the purpose of coloring.

[0003] In response, Chinese patent application number CN 220947126 U discloses a waterless printing device for fabric textiles, relating to the field of textile printing technology. This utility model includes a rectangular base plate and two support plates fixedly installed on the top of the rectangular base plate. The rectangular base plate is equipped with an adjustment mechanism, an auxiliary mechanism, a printing mechanism, and a winding mechanism. The adjustment mechanism includes an adjustment component and a limiting component. The adjustment component includes strip-shaped grooves respectively formed on one side of the two support plates close to each other. An adjusting threaded rod is rotatably installed in the corresponding strip-shaped groove. A T-shaped plate is threaded onto the adjusting threaded rod. An adjusting motor is fixedly installed on the top of the corresponding support plate. The top of the strip-shaped groove extends beyond the corresponding support plate and is fixedly connected to the output shaft of the adjusting motor. This utility model, by setting an adjustment mechanism, enables the fabric to be tightened, preventing any impact on the printing effect during printing.

[0004] However, when this structure is used in actual waterless printing operations through heat transfer printing equipment, due to its own structural limitations, it can often only perform one-by-one printing operations on the fabric pattern, resulting in low overall printing efficiency of the equipment. At the same time, the equipment cannot quickly transport and connect the fabric and the printing paper, and cannot achieve continuous and efficient heat transfer printing operations, thus failing to meet daily usage needs. Therefore, it is urgent to design a waterless printing device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a waterless printing device to solve the problems mentioned in the background art. When the existing structure is used for actual waterless printing operations through heat transfer printing equipment, due to its own structural limitations, it can often only perform one-by-one printing operations on the fabric pattern, resulting in low overall printing efficiency of the equipment. At the same time, the equipment cannot quickly transport and connect the fabric and the printing paper, and cannot achieve continuous and efficient heat transfer printing operations, thus failing to meet the needs of daily use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a waterless printing device, comprising a printing frame, an upper shrinking frame fixedly connected to the top of the printing frame, a lower shrinking frame fixedly connected to the bottom of the printing frame, electric push rods provided at the upper and lower ends of the upper and lower shrinking frames, and heat printing frames provided at intervals inside the printing frame;

[0007] The upper shrink frame has a feed roll frame and a take-up roll frame. The feed roll frame is fixedly connected to both sides of the upper shrink frame, and the take-up roll frame is fixedly connected to both sides of the lower shrink frame. A transmission frame is fixedly connected to the back of the take-up roll frame, and a take-up motor is provided at one end of the back of the transmission frame.

[0008] Preferably, the bottom end of the feed roll frame and the take-up roll frame is provided with a movable shaft, and the sides of the feed roll frame and the take-up roll frame are movably connected to a sealing arc cover through the movable shaft.

[0009] Preferably, the bottom end of the take-up roll is fixedly connected to a support base, and the support base has an internal support groove.

[0010] Preferably, the upper retractable frame is provided with a top pressure spring frame inside, and a top pressure plate is provided at the bottom end of the top pressure spring frame.

[0011] Preferably, the inner wall of the heat printing frame is provided with a shrink sleeve, and the heat printing unit is arranged in the center of the heat printing frame through the shrink sleeve.

[0012] Preferably, the printing frame has conveying grooves on both sides that are offset from the heat printing frame, and guide rollers are provided inside the conveying grooves.

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

[0014] 1. This waterless printing device, through its printing frame, upper shrink frame, lower shrink frame, electric push rod, heat printing frame, top pressure spring frame, top pressure plate, shrink sleeve, and heat printing unit, enables the equipment to perform multiple synchronized heat transfer waterless printing operations. In actual use, the operator first installs the fabric to be printed and the heat transfer printing paper layer by layer alternately inside the printing frame via the heat printing frame. Once the fabric and heat transfer printing paper are installed inside the printing frame, the upper and lower shrink frames can be started simultaneously. The electric push rods at both ends drive the top pressure spring frame and the top pressure plate to perform synchronous up-and-down pressing operations from the top and bottom ends of the printing frame. This allows the fabric and printing paper between all the heat printing frames to be squeezed and heat transferred through the internal shrink sleeve and heat printing unit. At the same time, the top pressure spring frame shrinks accordingly when the top pressure plate presses up and down, ensuring that the top pressure plate can apply more secure up-and-down force to the heat printing unit inside all the heat printing frames. This improves the heat transfer printing effect between each layer of printed fabric and heat transfer printing paper, demonstrating the practicality of the equipment design.

[0015] 2. This waterless printing device, through its feed roll rack, take-up roll rack, transmission frame, take-up motor, movable shaft, sealing arc cover, conveyor trough, and guide rollers, further improves the overall efficiency of the equipment. In daily use, operators can place the fabric and printing paper into the feed roll racks on both sides of the upper shrink frame, then thread them through the printing frame, and finally quickly rewind them using the take-up roll racks on both sides of the lower shrink frame. The feed roll rack and take-up roll rack can be quickly opened via the movable shaft and sealing arc cover, enabling rapid loading and unloading of fabric and printing paper, thus improving the printing efficiency. The conveyor troughs and guide rollers on both sides of the printing frame, designed to be offset from the heat-pressing frame, allow for cross-feeding and guiding of the fabric and printing paper, demonstrating the comprehensiveness of the equipment design.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 One embodiment provided by this utility model:

[0023] A waterless printing device includes a printing frame 1, an upper shrink frame 2 fixedly connected to the top of the printing frame 1, and a lower shrink frame 3 fixedly connected to the bottom of the printing frame 1. Electric push rods 4 are provided at the upper and lower ends of the upper and lower shrink frames 2 and 3. A heat-printing frame 5 is spaced apart inside the printing frame 1. A top pressure spring frame 14 is provided inside the upper shrink frame 2, and a top pressure plate 15 is provided at the bottom end of the top pressure spring frame 14. A shrink sleeve 16 is provided on the inner wall of the heat-printing frame 5. The center of the heat-printing frame 5 is oriented through a shrink sleeve. The sleeve 16 is equipped with a heat printing unit 17. The printing frame 1 has conveying grooves 18 on both sides that are offset from the heat printing frame 5. The conveying grooves 18 are equipped with guide rollers 19. The electric push rods 4 at the upper and lower ends of the upper shrink frame 2 and the lower shrink frame 3 are started simultaneously, so that they drive the top pressure spring frame 14 and the top pressure plate 15 to perform synchronous up and down pressing operations from the upper and lower ends of the printing frame 1. All the fabric and printing paper between the heat printing frames 5 are squeezed and heat transferred through the internal shrink sleeve 16 and heat printing unit 17.

[0024] The feed roll 6 and take-up roll 7 are fixedly connected to both sides of the upper shrink frame 2 and the take-up roll 7 is fixedly connected to both sides of the lower shrink frame 3. The back of the take-up roll 7 is fixedly connected to the transmission frame 8. A winding motor 9 is provided at one end of the back of the transmission frame 8. The bottom of the feed roll 6 and take-up roll 7 is provided with a movable shaft 10. The sides of the feed roll 6 and take-up roll 7 are movably connected to a sealing arc cover 11 through the movable shaft 10. The bottom of the take-up roll 7 is fixedly connected to a support base 12. The interior of the support base 12 is provided with a support groove 13. The fabric and printing paper are respectively placed into the feed roll 6 on both sides of the upper shrink frame 2, and then inserted into the printing frame 1. After that, they are quickly wound up by the take-up roll 7 on both sides of the lower shrink frame 3. The feed roll 6 and take-up roll 7 can be quickly opened by the movable shaft 10 and the sealing arc cover 11.

[0025] Working Principle: During operation, the user first inserts the fabric to be printed and the heat transfer printing paper into the printing frame 1, alternating layers within the heat printing frame 5. Once the fabric and heat transfer printing paper are installed inside the printing frame 1, the electric push rods 4 at both ends of the upper shrink frame 2 and lower shrink frame 3 can be activated simultaneously. This drives the top pressure spring frame 14 and the top pressure plate 15 to perform synchronized up-and-down pressure operations from both ends of the printing frame 1. All the fabric and printing paper between the heat printing frames 5 are compressed and heat transferred through the internal shrink sleeve 16 and the heat printing unit 17. Simultaneously, the top pressure spring frame 14 retracts accordingly during the up-and-down pressure of the top pressure plate 15, ensuring a more secure fit between the top pressure plate 15 and the heat printing unit 17 inside all the heat printing frames 5. The upward and downward force improves the heat transfer printing effect between the fabric and the heat transfer printing paper of each layer of printing. In daily use, the staff can put the fabric and printing paper into the feed roll 6 on both sides of the upper shrink frame 2, and then insert them into the printing frame 1. After that, they can be quickly rolled up by the take-up roll 7 on both sides of the lower shrink frame 3. The feed roll 6 and take-up roll 7 can be quickly opened by the movable shaft 10 and the sealing arc cover 11, thereby realizing the rapid loading and unloading of fabric and printing paper and improving the printing efficiency of the equipment. Through the conveying groove 18 and guide roller 19 on both sides of the printing frame 1 that are staggered with the heat printing frame 5, the fabric and printing paper can be guided and limited back and forth cross-feeding. The above is the complete working principle of this utility model.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
