[0024] In order to make the purpose, technical scheme and advantage of the utility model more clear, the technical scheme in the utility model will be described clearly and completely below by combining with the drawings in the utility model, obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0025] In the first aspect, the utility model embodiment provides a textile fixture, please refer to Figs. 1-3 , including expansion and contraction mechanism 10, first cloth board 20 and second cloth board 30, first cloth board 20 and second cloth board 30 are set apart and set up on expansion and contraction mechanism 10, and first cloth board 20 and second cloth board 30 are moved along the radial direction of expansion and contraction mechanism 10 by expansion and contraction of expansion and contraction mechanism 10;In the contracted state, second cloth board 30 is located in the space enclosed by first cloth board 20, and in the stretched state, the edge of first cloth board 20 and second cloth board 30 is abutted.

[0026] The textile fixture of the embodiment is used, first cloth board 20 and second cloth board 30 are set on expansion and contraction mechanism 10, and first cloth board 20 and second cloth board 30 are expanded and contracted by the expansion and contraction of expansion and contraction mechanism 10.Expansion and contraction mechanism 10 contracts, and first cloth board 20 and second cloth board 30 contract, so that second cloth board 30 is in the space enclosed by first cloth board 20.At this time, the diameter of the whole textile fixture is also reduced, and the textile can be easily set on the textile fixture.Then expansion and contraction mechanism 10 is stretched, and first cloth board 20 and second cloth board 30 are stretched, thereby supporting the textile.The textile fixture in the utility model can realize the purpose of conveniently setting the textile on the textile fixture.

[0027] In an embodiment, in the stretched state, the outer surface of first cloth board 20 and second cloth board 30 constitutes a circumferential surface.

[0028] In the present embodiment, the outer sides of the first set of cloth plates 20 and the second set of cloth plates 30 are curved, and the outer sides of the first set of cloth plates 20 and the second set of cloth plates 30 are connected to form a circular shape. This design makes the first set of cloth plates 20 and the second set of cloth plates 30 in the unfolded state generally have a circular outer periphery, thereby facilitating more uniform support of the textile.

[0029] In an embodiment, the number of the first set of cloth plates 20 and the second set of cloth plates 30 is four.

[0030] In the present embodiment, the number of the first set of cloth plates 20 is four in the textile tool retracted state, and can also form a cylindrical outer periphery.

[0031] Of course, the number of the first set of cloth plates 20 can also be other numbers. For example, two, three, or five or more. It should be noted that the width of the first set of cloth plates 20 is generally much greater than the width of the second set of cloth plates 30.

[0032] In an embodiment, the surfaces of the first set of cloth plates 20 and the second set of cloth plates 30 are coated with Teflon.

[0033] Teflon is the common name of polytetrafluoroethylene (PTFE), which is a high molecular compound formed by polymerization of tetrafluoroethylene. Teflon tube has excellent non-stick properties, and almost all substances do not adhere to Teflon, and even a very thin film also shows non-stick properties. This makes it difficult for molten textile material to clog or stick when flowing in the tube, ensuring the continuity and stability of the printing process. Teflon tube can withstand a working temperature of up to 260°C, meeting the conveying needs of high-temperature materials in textile printing, ensuring stability under long-term high-temperature work, thereby ensuring the smooth progress of the printing process. The friction coefficient of the Teflon tube is small, and the resistance experienced by the plastic when flowing in the tube is small, which helps to improve the printing speed and efficiency, and also helps to reduce the wear of the textile in the tube, avoiding damage to the textile.

[0034] In an embodiment, the expansion and contraction mechanism 10 includes a cylinder mounting shaft 110 and an expansion and contraction cylinder 120, and the expansion and contraction cylinder 120 is mounted on the cylinder mounting shaft 110.

[0035] The telescopic pneumatic cylinder 120 is a kind of pneumatic actuator, which drives the piston to perform telescopic movement through the change of air pressure. The working principle of the telescopic pneumatic cylinder 120 is to drive the piston to perform telescopic movement through the change of air pressure. When compressed air enters one end of the cylinder, it pushes the piston to move forward to realize the extension action. When compressed air enters the other end of the cylinder, it pushes the piston to move backward to realize the retraction action. Such a cylinder can be single-acting or double-acting, depending on its design and application requirements.

[0036] The cylinder mounting shaft 110 is mainly used for mounting the telescopic pneumatic cylinder 120 and connecting with the main body of the textile printer.

[0037] In an embodiment, the diameter of the textile fixture in the contracted state is not more than 65 cm, and the diameter of the textile fixture in the expanded state is not more than 80 cm.

[0038] In this embodiment, the diameter of the textile fixture in the contracted state is not more than 65 cm, and the diameter of the textile fixture in the expanded state is not more than 80 cm. Generally, the diameter of the textile is 80 cm.

[0039] In an embodiment, the distance between the first cover plate 20 and the second cover plate 30 in the expanded state is not more than 0.1 cm.

[0040] In this embodiment, the distance between the first cover plate 20 and the second cover plate 30 in the expanded state is not more than 0.1 cm. This is mainly because the textile needs to be supported during printing, so that the printing on the textile can be realized. The distance between the first cover plate 20 and the second cover plate 30 not more than 0.1 cm can support the basic requirements of printing, and ensure that the textile does not deform significantly during printing.

[0041] In a second aspect, the utility model provides a kind of textile printer, including rotary joint 60 and the textile fixture of any one of first aspect, rotary joint 60 is rotationally connected with textile fixture.

[0042] Using the textile printer of this embodiment, since rotary joint 60 connects textile fixture, the rotation of textile fixture can be realized, so that the printer head can be kept stationary, and printing on the circumference of the textile can be realized. The textile printer in the utility model can be conveniently set on the textile fixture.

[0043] Rotary joint 60 generally has a rotating part and a connecting part, which are rotationally connected. Specifically, the connecting part is provided with a motor, and the transmission shaft of the motor is connected with the rotating part. The motor controls the rotation of the rotating part through numerical control.

[0044] In an embodiment, a main shaft 40 is further included for telescoping.

[0045] The main shaft 40 can be telescoped to move the textile relative to the printer head along the axial direction of the textile fixture. In combination with the rotation of the rotary joint 60, printing can be performed on various regions of the textile.

[0046] In an embodiment, a mounting plate 50 is further included to be disposed between the textile fixture and the main shaft 40.

[0047] In the embodiment, the mounting plate 50 is first fixed to one end of the main shaft 40, and then the rotary joint is fixed to the mounting plate 50. This is mainly because the mounting plate 50 is provided with a plurality of fastening screw holes, and the rotary joint 60 is fixed to the mounting plate 50 by fastening bolts passing through the fastening screw holes.
