DETAILED DESCRIPTION

[0024] Example 1

[0025] like Figure 1-3 As shown, a fast air-drying woven bag printing machine includes a body 1, which is provided with a feed port 11 and a discharge port 12, the feed port 11 is connected to a first conveying plate 4, the discharge port 12 is connected to a second conveying plate 3, the first conveying plate 4 is fixed with a first bracket 41 and a flattening component 6, the first bracket 41 is equipped with a pressure roller 5, the pressure roller 5 is located between the flattening component 6 and the feed port 11, the second conveying plate 3 is fixed with a conveying component 2 for conveying woven bags 7, a first printing roller 8 and a second printing roller 9 are installed inside the body 1, a first air-drying device 13 is installed on one side of the first printing roller 8, and a second air-drying device 14 is installed on one side of the second printing roller 9.

[0026] The first air-drying device 13 and the second air-drying device 14 are both composed of a structure in which a fan is hingedly connected to a bracket. The angle of the fan can be adjusted to the optimal position according to needs, so as to air-dry the woven bag after printing.

[0027] The flattening assembly 6 includes a flattening bracket 61, a mounting rod 62, a spring 63, a mounting piece 64 and a ball 65. The upper end of the mounting rod 62 is fixed to the bottom of the flattening bracket 61, and the lower end of the mounting rod 62 is slidably connected to the mounting piece 64. The spring 63 is sleeved on the outside of the mounting rod 62 and is located between the flattening bracket 61 and the mounting piece 64. The ball 65 is installed at the bottom of the mounting piece 64.

[0028] The mounting member 64 is provided with a slide groove 641 , and the bottom of the mounting rod 62 is slidably connected to the slide groove 641 . The diameter of the bottom of the mounting rod 62 is larger than the diameter of the notch of the slide groove 641 .

[0029] The diameter of the bottom of the mounting rod 62 is larger than the diameter of the slot of the slide groove 641 , and plays a role of limiting to prevent the mounting member 64 from being separated from the mounting rod 62 during the sliding process.

[0030] The diameter of the bottom of the mounting member 64 is smaller than the diameter of the ball 65 .

[0031] The diameter of the bottom of the mounting member 64 is smaller than the diameter of the ball 65, which acts as a limit to prevent the ball 65 from falling out of the bottom of the mounting member 64. The bottom of the mounting member 64 is a structure with a certain cavity, in which the ball 65 can be placed, so that the ball 65 can roll freely without falling out.

[0032] The transmission assembly 2 includes a second bracket 21, a transmission wheel 22, a transmission shaft 23 and a driving motor 24. The second bracket 21 is fixed to the second transmission plate 3, the transmission wheel 22 is fixed to the transmission shaft 23, the transmission shaft 23 is connected to the second bracket 21, and one end of the transmission shaft 23 passes through the second bracket 21 and is connected to the driving motor 24.

[0033] The transmission shaft 23 is connected to the second bracket 21 through a bearing. When the driving motor 24 is working, it drives the transmission shaft 23 to rotate, thereby driving the transmission wheel 22 to rotate. The transmission wheel 22 abuts against the woven bag 7, driving the woven bag 7 to move, thereby providing the woven bag 7 with power for displacement.

[0034] The transmission wheel 22 is provided with a number of rubber pads 221. The rubber pads 221 are used to increase friction.

[0035] The first printing roller 8 and the second printing roller 9 are located in the same vertical direction.

[0036] The flattening component 6 is in an eight-shaped shape.

[0037] The working principle of this device is as follows: first, the woven bag 7 is passed through the flattening component 6, the pressure roller 5, the second printing roller 9, the first printing roller 8, and the transmission wheel 22 in sequence, and then the printing work is started, and the drive motor 24 is started to drive the transmission shaft 23 to rotate, thereby driving the transmission wheel 22 to rotate, and the transmission wheel 22 is abutted against the woven bag 7 to drive the woven bag 7 to move. The woven bag 7 is flattened by the flattening component 6, and then flattened by the pressure roller 5, and then printed on both sides by the second printing roller 9 and the first printing roller 8, and is air-dried by the first air-drying device 13 and the second air-drying device 14, and is transmitted from the second transmission plate 3 to complete the printing work.

[0038] Example 2

[0039] The difference between this embodiment and the first embodiment is that heating wires are installed in the first air-drying device 13 and the second air-drying device 14 to blow out hot air during operation to accelerate the drying and solidification of the printed pattern.

[0040] Example 3

[0041] The difference between this embodiment and embodiment 1 is that the number of the transmission wheels 22 is set to three or four according to the specific scene requirements to ensure that the surface of the woven bag 7 is evenly stressed and there is no displacement tilt caused by uneven stress.

[0042] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
