DETAILED DESCRIPTION

[0023] The following will be combined with 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 of 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.

[0024] See also Figure 1 and Figure 2 The utility model provides a technical solution: a pressing device for a color printing device for processing environmentally friendly woven bags, comprising two vertically symmetrically arranged brackets 1, a driving rod 2 arranged horizontally and rotatably connected to the two brackets 1, and a motor 3 fixed to the outside of the bracket 1 and whose output shaft is fixed to the driving rod 2. Two sets of symmetrically arranged first slide seats 5 and second slide seats 6 are sleeved on the driving rod 2. Guide rods 4 for slidingly guiding the first slide seat 5 and the second slide seat 6 are arranged on both sides of the driving rod 2, and the two ends of the guide rod 4 are respectively fixed to the two brackets 1, and the second slide seat 6 is elastically connected to the bracket 1 through a spring 9. The driving rod 2 is provided with a first thread segment 21 which is threadedly matched with the first slide 5 and can drive the first slide 5 to move horizontally toward the second slide 6. The driving rod 2 is provided with two first thread segments 21 in total, and the thread directions of the two first thread segments 21 are opposite. An expansion component 7 is arranged between the first slide 5 and the second slide 6, and a pressing wheel 8 which is pushed by the expansion component 7 to flatten the woven bag when the first slide 5 and the second slide 6 are close to each other is arranged. The driving rod 2 is provided with a second thread segment 22 and a stopper 10 which is threadedly matched with the second thread segment 22 and can block the second slide 6 so that the pressing wheel 8 presses the woven bag.

[0025] See also Figure 3 , a through hole 61 for the driving rod 2 to pass through is opened in the middle position of the first slide 5 and the second slide 6, a threaded sleeve 51 is fixed in the through hole 61 of the first slide 5, and the threaded sleeve 51 is threadedly connected with the first threaded section 21 of the driving rod 2, and the spring 9 is sleeved outside the guide rod 4, and the two ends of the spring 9 are respectively abutted against the opposite surfaces of the second slide 6 and the bracket 1. When the motor 3 drives the driving rod 2 to rotate, the first threaded section 21 on the driving rod 2 can be threadedly matched with the two first slides 5 and the guide rod 4 can limit the first slide 5, so that the two first slides 5 can move toward the second slide 6. Because the second slide 6 is resisted by the spring 9, the moving position distance of the second slide 6 is shorter than that of the first slide 5, so that the distance between the first slide 5 and the second slide 6 is gradually reduced.

[0026] See also Figure 3The expansion support assembly 7 includes a first connecting rod 71 and a second connecting rod 72. The adjacent ends of the first connecting rod 71 and the second connecting rod 72 are hinged by a second rotating shaft 75. The bottom surfaces of the first slide 5 and the second slide 6 are fixed with hinge seats 73. The distant ends of the first connecting rod 71 and the second connecting rod 72 are respectively hinged to the hinge seats 73 on the bottom surfaces of the first slide 5 and the second slide 6 by a first rotating shaft 74. The pressure wheel 8 is fixed at the middle position of the second rotating shaft 75. The mutual approach of the first slide 5 and the second slide 6 compresses the first connecting rod 71 and the second connecting rod 72, thereby pushing the height of the pressure wheel 8 to gradually decrease until it conflicts with the woven bag. At this time, since the height position of the pressure wheel 8 remains unchanged, when the first slide 5 moves toward the end of the driving rod 2, it can push the second slide 6 to compress the spring 9 and move synchronously toward the end of the driving rod 2. In this process, the pressure wheel 8 presses the woven bag and smoothes it on the workbench.

[0027] See also Figure 4 The stop member 10 includes a sleeve 101, which is sleeved outside the driving rod 2 and threadedly connected to the second threaded section 22 on the driving rod 2. The end of the sleeve 101 close to the second slide 6 is rotatably connected to a stop ring 102 until the second slide 6 conflicts with the stop ring 102. At this time, the second slide 6 does not move, and the first slide 5 pushes the first connecting rod 71 and the second connecting rod 72 to compress the pressing wheel 8, so that the pressing wheel 8 presses the woven bag. The stagnation position of the pressing wheel 8 can be adjusted by manually screwing the sleeve 101, so that it is suitable for fixing woven bags of different widths.

[0028] It should be noted that a rubber gasket 103 is fixed to a side of the stop ring 102 close to the second slide seat 6 to play a buffering role, and an anti-slip pattern 104 is provided on the outer surface of the sleeve 101 to facilitate the screwing of the sleeve 101.

[0029] The working principle and use process of the utility model are as follows: when in use, the woven bag is placed on the workbench below the two pressing wheels 8, the motor 3 is turned on to drive the driving rod 2 to rotate, and the first threaded section 21 on the driving rod 2 is threadedly matched with the two first slide seats 5 and the guide rod 4 is guided and limited to the first slide seat 5, so that the two first slide seats 5 move toward the second slide seat 6, and because the second slide seat 6 is resisted by the spring 9, the movement position distance of the second slide seat 6 is shorter than that of the first slide seat 5, and the distance between the first slide seat 5 and the second slide seat 6 is gradually reduced, and the first slide seat 5 and the second slide seat 6 are close to each other to compress the first slide seat 6. The connecting rod 71 and the second connecting rod 72 push the height of the pressing wheel 8 to gradually decrease until it conflicts with the woven bag. At this time, since the height position of the pressing wheel 8 remains unchanged, the first slide 5 can push the second slide 6 to compress the spring 9 and move synchronously toward the end of the driving rod 2 when moving toward the end of the driving rod 2. In this process, the pressing wheel 8 presses the woven bag and smoothes it on the work surface until the second slide 6 conflicts with the stop ring 102. At this time, the second slide 6 stops moving, and the first slide 5 pushes the first connecting rod 71 and the second connecting rod 72 to compress the pressing wheel 8, so that the pressing wheel 8 presses the woven bag tightly to fix the woven bag for subsequent color printing.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
