[0002] Printing machines are relatively common in the market and can be applied to printing operations on a variety of materials, including paper, cloth, decorative materials, etc. When printing on cloth, the printing machine needs to use an auxiliary feeding mechanism to transport the cloth to the printing machine, so the use of the auxiliary feeding mechanism is indispensable.

[0003] For example, the publication number CN218707750U discloses a digital printing machine feeder, which belongs to the field of digital printing machine feeding and conveying technology. The utility model includes a substrate, and a printing machine is fixedly connected to the left side of the top of the substrate. The printing machine includes a shell, a feed drive device and a discharge drive device, and the shell is fixedly connected to the left side of the top of the substrate. The utility model sets a transmission mechanism, which can move the top transmission roller downward, so that the top transmission roller and the bottom transmission roller fix the cloth to prevent the cloth from moving back and forth, and then move the top electrostatic dust removal roller downward through the lifting mechanism, and remove dust from the top and bottom of the cloth through the bottom electrostatic dust removal roller and the top electrostatic dust removal roller, thereby achieving the effect of removing dust, solving the problem that the digital printing machine cannot remove dust. The digital printing machine feeder has the advantage of removing dust. The dust on the cloth can be removed during use, and will not affect the printing and dyeing effect during printing and dyeing;

[0004] However, the printing machine feeder in the above application still has some shortcomings during use. For example, it is not convenient to perform anti-wrinkle treatment on the cloth, so the cloth transported to the printing machine is also wrinkled, which affects the printing effect and reduces the use effect of the feeder. Therefore, we propose a printing machine auxiliary feeding mechanism with a double-roller anti-wrinkle structure to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Embodiment 1:

[0033] In this embodiment, when the cloth is conveyed, the cleaning block 8 can clean the upper and lower surfaces of the cloth to reduce the adsorption of dust. Figure 1-Figure 2 and Figure 4 As shown:

[0034] A side baffle 3 is installed above the bearing bottom plate 2, and a hydraulic rod 4 is fixed to the inner surface of the side baffle 3 by bolts, and the output end of the hydraulic rod 4 is connected to a top plate 5;

[0035] The support frame 1 and the side baffle plate 3 are both welded to the bearing bottom plate 2, and two side baffle plates 3 are provided, and the two side baffle plates 3 are symmetrically distributed about the transverse center line of the support frame 1, and a lower pressure roller 6 and a cleaning roller 7 are installed between the bearing bottom plates 2, the lower pressure roller 6 and the bearing bottom plate 2 are connected by bearings, and the lower pressure roller 6 is evenly spaced between the bearing bottom plates 2 on the front and rear sides, and the cleaning roller 7 is fixed to the bearing bottom plate 2 by screws, and a cleaning block 8 is provided on the outer wall of the cleaning roller 7, and the cleaning block 8 is in an arc shape, and the cleaning block 8 is made of sponge, and the cleaning block 8 and the cleaning roller 7 are bonded, and the length of the cleaning block 8 is the same as the length of the cleaning roller 7;

[0036] When using the auxiliary feeding mechanism of the printing machine with a double-roller anti-wrinkle structure, first, the support frame 1 of the feeding mechanism is placed horizontally in the corresponding position, a bearing base plate 2 is fixed above the support frame 1, and a lower pressing roller 6 and a cleaning roller 7 are arranged between the bearing base plates 2 on the front and rear sides, and the lower pressing roller 6 and the cleaning roller 7 are both connected to the bearing base plate 2 by bearings. At the same time, two cleaning rollers 7 are arranged, so the cloth can be bypassed between the two cleaning rollers 7, and then the cloth is brought into contact with the lower pressing roller 6, that is, the cloth first passes under the outermost cleaning roller 7, and then goes around the inner cleaning roller 7. In this way, when the cloth is pulled, the cloth will first pass through the two cleaning rollers 7, and then pass through the lower pressing roller 6 for conveying and feeding. A cleaning block 8 is installed on the outer wall of the cleaning roller 7, and the cleaning block 8 is made of sponge material. In this way, when the cloth is conveyed, the cleaning block 8 can clean the upper and lower surfaces of the cloth to reduce the adsorption of dust.

[0037] Embodiment 2:

[0038] In this embodiment, the upper pressing roller 10 and the lower pressing roller 6 can respectively press the upper and lower surfaces of the cloth tightly to achieve the purpose of wrinkle-proofing the cloth. Figure 3 and Figure 5-Figure 6 As shown:

[0039] The lower surface of the top plate 5 is connected to one end of the fixing rod 9, and the other end of the fixing rod 9 is connected to the upper pressure roller 10. A limit block 14 is installed on the side wall of the top plate 5, and the limit block 14 forms a sliding structure through a connecting groove 15 and the side baffle 3, and the connecting groove 15 is opened on the side baffle 3;

[0040] Then start the hydraulic rod 4, which will push the top plate 5 down. A fixed rod 9 is provided under the top plate 5, and the fixed rod 9 and the upper pressing roller 10 are connected by a bearing. In this way, when the top plate 5 descends, the fixed rod 9 and the upper pressing roller 10 will be driven to descend together, so that the upper pressing roller 10 will contact the upper surface of the cloth. In this way, as the cloth is pulled, the upper pressing roller 10 and the lower pressing roller 6 can be respectively pressed against the upper and lower surfaces of the cloth, so that the cloth can be wrinkle-proofed to ensure the flatness of the cloth. In addition, a limiting block 14 is provided on the side wall of the top plate 5. The limiting block 14 forms a sliding structure through the connecting groove 15 and the side baffle 3. In this way, under the action of the limiting block 14, the top plate 5 can move more smoothly, ensuring the normal wrinkle-proofing of the cloth.

[0041] Embodiment three:

[0042] In this embodiment, the heat on the surface of the upper pressing roller 10 and the lower pressing roller 6 can be used to better prevent the wrinkles on the fabric, which provides convenience for the later processing of the fabric. Figure 7 As shown:

[0043] The upper pressing roller 10 and the fixed rod 9 are connected by a bearing, and a fixed shaft rod 11 is arranged inside the upper pressing roller 10, and an electric heating wire 12 is arranged between the fixed shaft rod 11 and the upper pressing roller 10, and a battery pack 13 is installed inside the fixed shaft rod 11;

[0044] The battery pack 13 and the electric heating wires 12 are electrically connected, and the electric heating wires 12 are distributed at equal angles. The internal structure of the lower pressing roller 6 is the same as the internal structure of the upper pressing roller 10;

[0045] Since the upper pressing roller 10 and the lower pressing roller 6 have the same internal structure, a fixed shaft rod 11 is arranged inside the upper pressing roller 10, and electric heating wires 12 distributed at equal angles are arranged between the fixed shaft rod 11 and the inner wall of the upper pressing roller 10, and the electric heating wires 12 and the battery pack 13 arranged on the inner side of the fixed shaft rod 11 are electrically connected. In this way, when the cloth is subjected to wrinkle-proof treatment, the electric heating wire 12 can be powered by the battery pack 13. The electric heating wire 12 will generate heat when working, and the heat will be transferred to the outer surface of the upper pressing roller 10. Similarly, the outer surface of the lower pressing roller 6 will also generate heat. Therefore, the wrinkle-proof treatment of the cloth is more effective, which provides convenience for the later processing of the cloth. The above is the working process of the entire device. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
