Description

Technical Field

[0001] The invention relates to the technical field of knitted fabric printing, in particular to an anti-adhesion knitted fabric printing device. Background Art

[0002] With the rapid development of my country's clothing industry, clothing equipment has been continuously updated and developed, and its functional, intelligent, automatic and high-speed features have become more obvious. The widespread adoption of high-tech at home and abroad in clothing equipment has ensured the overall improvement of clothing manufacturing technology and quality. Knitted fabric printing equipment is a mechanical equipment for some personalized printing on knitted fabrics. The traditional knitted fabric printing method is thermal transfer. Before transfer printing on knitted fabrics, sublimation dye ink is first printed on specific printing paper with a printing machine to become transfer printing paper, and then the patterned side of the printing paper is pressed against the cloth to transfer the dye ink on the transfer printing paper to the cloth.

[0003] However, the existing printing winding device has the following disadvantages. First, due to the presence of some water in the dye ink and the slightly humid air, the drying stroke of the printed fabric is short, so that the fully dried fabric is rolled into the winding roller and is prone to adhesion after being wound up by the winding roller. Second, during the drying process, due to the large contact area between the fabric and the guide roller, the sudden evaporation of the ink on the fabric will cause adhesion to the guide roller, resulting in unfavorable pulling on the fabric. Summary of the invention

DETAILED DESCRIPTION

[0025] The embodiment of the present invention provides a knitted fabric printing device for preventing adhesion, such as Figure 1-6 As shown, the box body 1 includes a feed port 11 and a discharge port 12. A pair of feed rollers 13 and a discharge roller 14 are respectively provided on the feed port 11 and the discharge port 12. The feed rollers 13 and the discharge rollers 14 are used to introduce the cloth 6 into the box body 1 and out of the box body 1. The front and rear of the feed rollers 13 and the discharge rollers 14 are connected to the printing machine and the winding roller respectively.

[0026] A drying nozzle 4 is arranged on the top of the box body 1, and the drying nozzle 4 is connected to a hot air source through an air pump. The hot air source is not the focus of protection in this case, and electric air heating can be used, which will not be described in detail.

[0027] The box body 1 is provided with a plurality of guide rollers 2 alternately arranged up and down along the feeding direction of the cloth 6. A stroke adjustment mechanism 3 for adjusting the vertical spacing between two adjacent guide rollers 2 is arranged in the box body 1. The stroke adjustment mechanism 3 includes a motor 33, a plurality of double-sided racks 31, a plurality of gears 32, and a guide rail 34. The number of the double-sided racks 31 is consistent with the number of the guide rollers 2, and the number of the gears 32 is one less than the double-sided racks 31. The guide rollers 2 are rotatably connected to the plurality of double-sided racks 31 one by one. The guide rail 34 is vertically arranged in the box body 1. The double-sided racks 31 are slidably adapted to the guide rail 34 through a slider. A gear 32 is meshed between two adjacent double-sided racks 31. The gears 32 are all rotatably arranged on the box body 1. The motor 33 is arranged on the box body 1 and is connected to one of the gears 32.

[0028] like Figure 3 As shown, when the motor 33 drives one of the gears 32 to rotate, the gear 32 will drive the two double-sided racks 31 on both sides to move vertically in different directions. By changing the vertical spacing between the guide rollers 2 on the two adjacent double-sided racks 31, the total stroke length of the cloth 6 in the box 1 can be adjusted. The stroke of the cloth 6 can be adjusted according to the ink humidity or drying power on different types of cloth 6, which can ensure the drying effect while improving the drying efficiency.

[0029] Each guide roller 2 is provided with a contact area adjustment mechanism 5 which can change the contact area between the cloth 6 and the guide roller 2. During the drying process, the contact area between the cloth 6 and the guide roller 2 is adjusted by the contact area adjustment mechanism 5, so as to effectively avoid the adhesion of the cloth 6 to the outer wall of the guide roller 2 during the drying process and avoid defects in the printed part of the cloth.

[0030] Two groups of contact area adjustment mechanisms 5 are provided on each guide roller 2 , and the two groups of contact area adjustment mechanisms 5 are symmetrically arranged on both sides of the guide roller 2 .

[0031] like Figure 4-5 As shown, the contact area adjustment mechanism 5 includes an electric push rod 50, a guide shaft 53, a sliding shaft 54, a sliding sleeve 58, four groups of protrusions 51, a sliding groove 55, and a sliding seat 56. The four groups of protrusions 51 are respectively distributed at equal angles around the center of the guide roller 2. The guide shaft 53 and the sliding shaft 54 ​​are connected end to end and are coaxially arranged in the guide roller 2. The outer wall of the guide roller 2 is provided with a telescopic groove 52 for the protrusion 51 to extend. Four sliding grooves 55 are axially arranged on the guide shaft 53. The sliding seat 56 is axially slidably adapted on the sliding groove 55. The sliding seat 56 is hinged to the protrusion 51 through two connecting rods 57. The two connecting rods 57 are arranged in parallel. The sliding sleeve 58 is sleeved on the sliding shaft 54 ​​and connected to the sliding seat 56 through a connecting rod 59. The electric push rod 50 is axially arranged in the guide roller 2, and the output end is connected to the sliding sleeve 58.

[0032] The projection 51 is provided with an inclined surface 1 511 and an inclined surface 2 512 corresponding to the front and rear ends of the telescopic slot 52. The front end of the projection 51 is a vertical plane. When the connecting rod 57 is in a vertical state, the upper end points of the inclined surface 1 511 and the inclined surface 2 512 are both located outside the guide roller 2.

[0033] like Figure 6 As shown in FIG. 1 , when the electric push rod 50 pushes the sliding sleeve 58 to move toward the telescopic slot 52, the protrusion 51 is initially contained in the guide roller 2, and the connecting rod 57 is tilted. When the top of the protrusion 51 contacts the solid surface in the middle of the guide roller 2, the solid surface is flush with the outer end of the telescopic slot 52, and the protrusion 51 moves out of the guide slot 52, and the connecting rod 57 gradually tends to be vertical, and finally reaches the position shown in FIG. Figure 6The cloth 6 is supported by the protruding bumps 51, so that most of the cloth 6 is suspended, and the contact area between the cloth 6 and the guide roller 2 is greatly reduced, which effectively avoids the adhesion of the cloth 6 to the outer wall of the guide roller 2 during the drying process.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
