[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. When the number of an element is referred to as "plurality", it may be any number of two or more. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific implementations and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] The present invention is described in detail below in conjunction with the embodiments shown in the accompanying drawings:

[0024] like Figure 1-2As shown, in this embodiment, a material pulling mechanism is provided, including a support frame 10, on which a material discharging support plate 1 and a paper pressing wheel 7 assembly are fixedly arranged. The pressure roller 12 mentioned below the material discharging support plate 1 and the paper pressing wheel 7 assembly can fit the finished product (printed cloth or paper) to the material discharging plate or the material pulling roller. The support frame 10 is rotatably connected to a material pulling roller, and the paper pressing wheel 7 assembly is mounted above the material pulling roller. The support frame 10 is also equipped with a pressure roller 12, which is arranged adjacent to the material pulling roller. A card slot is provided on the material discharging support plate 1, and a position-adjustable limit block 13 is clamped on the card slot. The paper pressing wheel 7 and the pressure roller 12 are both in contact with the side of the material pulling roller 11. This is to ensure that the finished product can be smoothly rolled up when the material pulling roller 11 is rolled up without any excess material running and wrinkles.

[0025] In this embodiment, the support frame 10 is also provided with a color-tracking electric eye assembly. Electric eye is a more popular term, and its professional term is sensor. Sensor is a physical device or biological organ that can detect and sense external signals and physical conditions (light, temperature, etc.). The color-tracking electric eye assembly includes a crossbar 3, a color recognition sensor 5 and a pair of longitudinal slides 2. The longitudinal slides 2 are fixedly connected to the support frame 10. The crossbar 3 is slidably arranged on the longitudinal slides 2. The crossbar 3 is slidably connected to the support frame 10 through the longitudinal slides 2. The position of the color recognition sensor 5 on the crossbar 3 is adjustable. To further elaborate, the crossbar 3 is provided with a card slot, and a snap-on 4 is installed on one side of the color recognition sensor. The snap-on 4 is snap-on on the crossbar 3. There is a sliding groove in the snap-on 4. The width of the sliding groove corresponds to the thickness of the crossbar 3. The snap-on 4 is threaded with a bolt handle for fixing the position of the snap-on 4 on the crossbar 3. When the position of the clip 4 needs to be fixed, the bolt handle is tightened so that one end of the bolt handle abuts against the cross bar 3 to fix the position of the clip 4.

[0026] In this embodiment, both ends of the pressing roller 12 are rotatably connected with a first bearing seat, the position of the first bearing seat on the pressing roller 12 remains unchanged, and the first bearing seat is slidably arranged in the support frame 10. The support frame 10 is also provided with an elastic buffer 6 for resetting the pressing roller 12. Because the drawing roller 11 will make the finished product roll together around the drawing roller 11 when winding, the diameter of the drawing roller 11 plus the thickness of the rolled finished product will make the pressing roller 12 gradually move away from the central axis of the drawing roller 11. In order to provide a certain compressive stress so that the pressing roller 12 can always approach the drawing roller 11, an elastic buffer is provided. In addition to buffering the bumps during the paper pressing process, it can also reset the pressing roller 12 to keep it and the finished product outside the drawing roller 11 for pressing.

[0027] In this embodiment, the discharge support plate 1 is a slotted hollow structure, and a hollow tube is connected to the bottom of the discharge support plate 1 for connecting a suction fan. After the suction fan is started, a certain negative pressure is generated on the surface of the discharge support plate 1, so the raw material (paper or cloth) will be adsorbed when passing through, and any excess material will also be adsorbed, so that the excess material can be buffered to avoid folding of the subsequent hand roll.

[0028] To further explain, the pressing wheel 7 assembly includes a driven roller 8 and a positioning seat 9, the driven roller 8 is sleeved with the pressing wheel 7, the pressing wheel 7 is fixedly connected to the driven roller 8, the positioning seat 9 is fixedly connected to the support frame 10, the two ends of the driven roller 8 are respectively fixedly provided with second bearing seats, the second bearing seats are slidably arranged in the positioning seat 9, and the positioning seat 9 is provided with an elastic buffer 6 for resetting the driven roller 8. Because the pressing wheel 7 needs to press the finished product all the time, the reasons and benefits of providing the elastic buffer 6 on the positioning seat 9 are consistent with the above.

[0029] In this embodiment, the limit block 13 includes a clamping seat and a limit rod, the limit rod sleeve is provided with a freely rotatable collar, the limit rod is fixedly connected to the clamping seat, and the clamping seat is clamped with the slot. The limit rod is fixed to a specific position of the discharge support plate 1 through the clamping seat, and the clamping seat has a bolt handle, which will make the clamping seat clamp the edge of the slot when tightened, and the collar is provided to facilitate the smooth passage of the raw material when it abuts against the raw material.

[0030] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. For ordinary technicians in this field, they can make several modifications and improvements without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
