DETAILED DESCRIPTION

[0022] 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.

[0023] Embodiment 1

[0024] See also Figures 1 to 6 The utility model provides a technical solution: a printing roller adjustment device for printing equipment, comprising: a bracket 1, a main wheel 2 is arranged between two groups of brackets 1, and a secondary wheel 3 is arranged on the surface of the main wheel 2;

[0025] The system further comprises: a monitoring component 4, which is arranged on the sides of the main wheel 2 and the auxiliary wheel 3, and monitors the bending state of the object to be printed through the monitoring component 4;

[0026] The adjusting component 5 is arranged on both sides of the secondary wheel 3. When the monitoring component 4 detects that the bending degree of the object to be printed exceeds the normal standard, the adjusting component 5 is controlled to work. The adjusting component 5 adjusts the position of the secondary wheel 3 on the surface of the main wheel 2 according to the bending state, and reversely trims the bent object to be printed by adjusting the position of the secondary wheel 3. The monitoring component 4 monitors the bending degree of the object to be printed. When the object is convex or concave, the two groups of bending states are identified by the monitoring component 4. At the same time, the adjusting component 5 is controlled to work according to the state monitored by the monitoring component 4. The angle of the secondary wheel 3 is adjusted by the adjusting component 5, so that the secondary wheel 3 reversely corrects the bending part of the object, thereby improving the flattening effect of the object.

[0027] The monitoring component 4 includes a fixing frame 41 fixed on the side wall of the bracket 1, and connecting plates 42 are fixed on the two end surfaces between the two groups of fixing frames 41, a distance sensor 1 43 is fixed on the surface of the upper connecting plate 42, and a distance sensor 2 44 is fixed on the surface of the lower connecting plate 42. The distance to the object to be printed is monitored by the distance sensor 1 43 and the distance sensor 2 44. When the object is transmitted between the distance sensor 1 43 and the distance sensor 2 44, if the position of the object close to the distance sensor 1 43 or the distance sensor 2 44 exceeds the normal standard, the distance sensor 1 43 or the distance sensor 2 44 transmits the monitored signal to the controller, which is conducive to the controller controlling the adjustment component 5 to work.

[0028] The adjusting assembly 5 includes a rotating disk 51 fixed at both ends of the secondary wheel 3, a gear 52 is fixed on the side of the rotating disk 51 at one end away from the secondary wheel 3, and the end of the gear 52 away from the secondary wheel 3 is fixedly connected to the output shaft of the motor 56, and the motor 56 provides a power source for the angular rotation of the secondary wheel 3. When the object to be printed bulges upward, the distance sensor 43 detects that the object to be printed is close, and the distance sensor 43 transmits a signal to the controller. The controller controls the gear 52 to rotate counterclockwise, so that the secondary wheel 3 rotates in the direction of the central axis of the main wheel 2 close to the distance sensor 43, and the secondary wheel 3 rotates to the side close to the distance sensor 43, and the convex part of the object is reversely bent and pressed by the extrusion of the secondary wheel 3 and the main wheel 2. Similarly, when the object to be printed is concave downward, the distance sensor 44 detects the proximity of the object, and controls the gear 52 to rotate clockwise, driving the secondary wheel 3 to rotate to the side away from the distance sensor 43, so as to achieve reverse extrusion of the concave part, so as to make the object flatter.

[0029] An opening 53 is provided inside the bracket 1, and the outer wall of the gear 52 is meshed with the rack plate 55, and the end face of the rack plate 55 is fixed to the inner wall of the fixing ring 54, and the outer wall of the fixing ring 54 is fixed to the inner wall of the opening 53. When the motor 56 works and drives the gear 52 to rotate, the gear 52 rotates, and with the cooperation of the rack plate 55, the gear 52 drives the secondary wheel 3 to rotate along the central axis of the main wheel 2, realizing the conduction operation, so that the rotation of the secondary wheel 3 is more stable.

[0030] Both sides of the surface of the motor 56 are slidably connected to the bracket 1 through a slider 57. A slide groove 58 cooperating with the slider 57 is provided inside the bracket 1. The sliding of the motor 56 is guided by the slider 57 and the slide groove 58, so that the sliding of the motor 56 on the surface of the bracket 1 is more stable, which is beneficial to the temperature angle adjustment of the auxiliary wheel 3 and improves the stability of the device.

[0031] Embodiment 2

[0032] A movable plate 61 is fixed to the side of the other end turntable 51 away from the secondary wheel 3, and the two ends of the surface of the movable plate 61 are slidably connected with the bracket 1 through the second slider 62. The surface of the bracket 1 is provided with a second slide groove 63 that cooperates with the second slider 62. Through the second slider 62 and the second slide groove 63, the movable plate 61 follows the movement of the secondary wheel 3 more stably, and the movement of the end face of the secondary wheel 3 is limited and guided, so that the rotation of the secondary wheel 3 is more stable.
