Description

TECHNICAL FIELD

[0001] The application relates to the field of digital printing machines, in particular to a digital printing machine for cloth. BACKGROUND

[0002] At present, digital inkjet printing is widely used in the digital textile printing industry. Digital inkjet printing requires a digital printing machine. During the printing process, the digital printing machine prints and dyes by means of ink jetting, without direct contact with the object, so as to ensure the integrity of the printed object and prevent the object from being deformed due to heat and pressure. The digital printing machine uses the direct output printing method of a computer, which is convenient and fast.

[0003] Since the ink of the digital printing machine is printed and dyed by means of jetting, the cloth is directly wound after printing, and the ink that has not completely dried will stain other positions of the cloth, resulting in poor printing effect of the cloth. CONTENT OF THE INVENTION

[0004] In order to dry the printed cloth quickly and reduce the staining of ink to other positions of the cloth, the application provides a digital printing machine for cloth.

[0005] The application provides a digital printing machine for cloth, which adopts the following technical scheme:

[0006] The digital printing machine for cloth comprises a printing machine body, a guide roller, a heating device and a transmission device, the guide roller is rotationally connected to the printing machine body, a channel for hot water flow is formed in the guide roller, and the heating device is used for introducing hot water into the guide roller.

[0007] By adopting the above technical scheme, the transmission device is used for driving the guide roller to rotate, the rotating guide roller is used for winding the computer cloth out of the printing machine body, and in this process, the guide roller abuts against the cloth. The heating device is used for introducing hot water into the guide roller, so as to increase the temperature of the guide roller, so that the temperature of the guide roller rises, the ink on the cloth is dried in the process of guiding the cloth to move, the staining of ink to other positions of the cloth is reduced, the printing effect of the cloth is good, the heating device is combined with the guide roller, no additional heating device is needed, and the structure is simple.

[0008] Optionally, the printing machine body is provided with two mounting members for mounting the guide roller, the two mounting members are distributed along the length direction of the guide roller, and the mounting member comprises a mounting block, a limiting block and a limiting bolt, the mounting block is arranged on the printing machine body, a placing groove for placing the guide roller is formed in the side wall of the mounting block, the limiting block is rotationally connected to the mounting block, and the tail of the limiting bolt passes through the limiting block and is threadedly connected to the mounting block, and the limiting block limits the guide roller from being separated from the placing groove.

[0009] By adopting the above technical scheme, the guide roller is in hot water for a long time, and a large amount of impurities may exist in the guide roller, and even the flow of hot water may be blocked, so that the guide roller needs to be cleaned regularly. The staff can first unscrew the limiting bolt from the mounting block, then rotate the limiting block to remove the guide roller from the mounting block, and the placing groove is used for rotating the guide roller. The mounting member has a simple and reliable structure.

[0010] Optionally, the guide roller is provided with a bearing, a containing groove is formed in the groove side wall of the placing groove, and the containing groove is used for clamping the outer side wall of the bearing. The limiting block is provided with an abutting block for abutting against the outer side wall of the bearing.

[0011] By adopting the above technical scheme, the bearing on the guide roller is used for rotating relative to the mounting member, which reduces the abrasion of the guide roller during rotation and prolongs the service life of the guide roller. When the guide roller is mounted on the mounting block, the bearing is limited by the containing groove and the limiting block, which reduces the jumping of the guide roller and improves the quality of fabric printing.

[0012] Optionally, the transmission device comprises a first gear, a second gear and a driving motor, the first gear is arranged on the guide roller, the second gear is rotationally connected to the printing machine body, and the driving motor is used for driving the second gear to rotate.

One end of the connecting pipe is arranged on the guide roller, and the other end of the connecting pipe is arranged on the heating box. The water pump is used for supplying water from the heating box to one of the heating pipes.

[0015] By adopting the technical scheme, the heating pipe in the heating box is used to heat the water in the heating box, the water after being heated enters the guide roller along the connecting pipe through the water pump, after the temperature of the guide roller rises, the hot water transfers heat to the side wall of the guide roller, after the cloth contacts the guide roller, the ink on the cloth is dried, the water originally in the guide roller enters the heating box through the connecting pipe again to be heated, forming a cycle, the water of the heating box is reused, and the specific heat capacity of water is greater than that of air, so the water temperature drops slowly, compared with using air as a medium, the water maintains the temperature for a longer time, so that the heating pipe can be intermittently operated, which meets the green environmental protection concept.

[0016] Optionally, the connecting pipe is provided with a rotating piece connected with the guide roller, the rotating piece comprises a rotating pipe and a nut, the rotating pipe is rotationally connected to one end of the connecting pipe, the end of the rotating pipe away from the connecting pipe is provided with a plurality of insertion blocks, the plurality of insertion blocks are distributed circumferentially along the axis of the connecting pipe, the end of the guide roller facing the rotating pipe is provided with a plurality of insertion grooves for clamping the insertion blocks, and the nut is rotationally connected to the connecting pipe and threadedly connected with the guide roller.

[0017] By adopting the technical scheme, since the guide roller needs to rotate, the connecting pipe is directly connected to the guide roller, which is easy to cause the connecting pipe to be twisted and unable to be used, and the connecting piece is used to solve the problem, the rotating pipe is rotationally connected to the connecting pipe and threadedly connected to the guide roller through the nut, so as to reduce the disconnection of the rotating pipe and the guide roller, and since the insertion blocks of the rotating block cooperate with the insertion grooves on the guide roller, the relative rotation of the rotating block and the guide roller is reduced, and the rotation of the nut relative to the rotating pipe when the guide roller rotates is reduced.

[0018] Optionally, the rotating piece further comprises a sealing ring, the sealing ring is arranged on the rotating pipe, and the sealing ring abuts against the end face of the guide roller.

[0019] By adopting the technical scheme, the sealing ring reduces the outflow of water between the connecting pipe and the guide pipe, so as to improve the sealing performance of the rotating piece.

[0020] Optionally, the connecting pipe is a hose.

[0021] By adopting the technical scheme, since the guide roller needs to be disassembled, the connecting pipe is a hose, which can provide sufficient disassembly space and is convenient for workers to disassemble, thereby improving work efficiency.

[0022] In summary, the present application has at least one of the following beneficial technical effects:

[0023] 1. The heating device passes hot water into the guide roller, and the hot water makes the temperature of the guide roller rise. In the process of guiding the fabric to be wound, the fabric contacts the heated guide roller, so that the ink on the fabric dries, and the ink stains other positions of the fabric after winding is reduced.

[0024] 2. The mounting member is used to detach the guide roller from the printing machine body, so as to facilitate the periodic maintenance of the guide roller.

[0025] 3. The rotating member is used for the rotating sealing connection between the heating device and the guide roller. BRIEF DESCRIPTION OF DRAWINGS
