[0023] In order to better implement this utility model, refer to Figure 1In one embodiment, the auxiliary moving device 3 includes two second screws 301 penetrating the lower part of the two moving columns 201, the threads of the two ends of the second screws 301 are opposite, one end of the second screws 301 penetrates the mounting plate 1, and a pulley 303 is sleeved on each of the two second screws 301, and the two pulleys 303 are connected by a belt 304, one of the second screws 301 is connected to the output end of the second motor 302, and the other end of the second screw 301 is mounted on the mounting plate 1. The second motor 302 drives the connected second screw 301 to rotate, and drives the pulley 303 set on the second screw 301 to rotate, and the pulley 303 rotates through the belt 304 to drive another pulley 303 to rotate, thereby driving another second screw 301 to rotate, so that the two moving columns 201 can be close to or away from each other, so that the correction mechanism can be used for correction of printed products of different widths. In order to facilitate the movement of the moving column 201, a plurality of sliding wheels 6 are provided at the bottom of the moving column 201.

[0024] In order to better implement this utility model, refer to Figure 1 In one embodiment, the adjusting component 2 includes two moving columns 201, a second mounting groove 204 is provided on the top of the moving column 201, a first screw 202 and a guide rod 208 are provided in the second mounting groove 204 along the direction of the second mounting groove 204, a second moving block 205 is sleeved on the first screw 202 and the guide rod 208 located in the same second mounting groove 204, the second moving block 205 has an internal thread that matches the external thread of the first screw 202, and a limiting bar 207 is connected to the opposite side of the two second moving blocks 205 through a connecting rod 206, the cross-section of the limiting bar 207 is L-shaped, and the grooves of the two limiting bars 207 are arranged oppositely, the lower end of the limiting bar 207 is close to the placement plate 7, and one end of the first screw 202 passes through the second mounting groove 204 and is externally connected to the output end of the first motor 203. The two first motors 203 synchronously drive the first screw 202 to rotate, thereby driving the second moving block 205 to move along the guide rod 208. The second moving block 205 moves with the limit bar 207 through the connecting rod 206, so that the distance from the groove of the limit bar 207 to the conveyor belt of the quality inspection machine can be adjusted according to the size of the printed matter. When the printed matter is transmitted to the correction mechanism, the printed matter will be separated from the conveyor belt and fall onto the placement plate 7. In order to ensure that the detection mechanism 5 can detect the printed matter, the corner of the printed matter will be framed by the horizontal and vertical parts of the limit bar 207, so that the two limit bars 207 frame the printed matter on the placement plate 7, and the printed matter transmitted to the placement plate 7 is neatly stacked layer by layer. The detection mechanism 5 can quickly detect the printing quality, can not only quickly detect but also neatly stack the detected printed matter, thereby improving the working efficiency of the quality inspection machine.

[0025] In order to better implement this utility model, refer to Figure 2In one embodiment, the tops of the two mounting plates 1 are both provided with a first mounting groove 101, a third screw 9 is provided along the first mounting groove 101, a first moving block 8 is sleeved on the two third screws 9, the first moving block 8 is provided with an internal thread matching the external thread of the third screw 9, a cross plate 4 is provided between the two first moving blocks 8, a detection mechanism 5 is installed at the bottom of the cross plate 4, and the third screw 9 is driven to rotate by an external motor (not shown in the figure). Since there are many sizes of printed products, in order to ensure that the detection mechanism 5 can be aligned with printed products of different sizes, so that the detection is more accurate and efficient, after adjusting the position of the limit strip 207, the position of the detection mechanism 5 needs to be adjusted. At this time, the third screw 9 can be driven to rotate by two motors at the same time, so that the two first moving blocks 8 drive the cross plate 4 to move, and drive the detection mechanism 5 to move.

[0026] In order to better implement this utility model, refer to Figure 1 In one embodiment, the straight line where the second mounting groove 204 is located is parallel to the direction in which the conveying device conveys the printed matter.

[0027] Based on the above-mentioned correction mechanism of a printed product inspection machine, its working principle is as follows:

[0028] Before correcting the deviation, it is necessary to first drive the connected second screw 301 to rotate through the second motor 302, and then drive the other second screw 301 to rotate through the pulley 303 and the belt 304 arranged thereon, so that the distance between the two moving columns 201 is closer or farther, and then drive the first screw 202 to rotate through the first motor 203, thereby driving the second moving block 205 arranged thereon to move along the guide rod 208, and the second moving block 205 drives the limit bar 207 to move through the connecting rod 206 to adjust the distance between the limit bar 207 and the conveyor belt. After adjusting the limit bar 207, the motor connected to the third screw 9 will drive the third The screw rod 9 rotates, thereby driving the first moving block 8 to move along the third screw rod 9, driving the cross plate 4 to move, so that the detection mechanism 5 installed at the bottom of the cross plate 4 can move to the top of the printed matter restricted by the limit bar 207. After the adjustment is completed, the printed matter can be inspected by the inspection machine. At this time, the conveyor belt conveys the printed matter to the correction mechanism, and the printed matter falls vertically onto the placement plate 7 along the limit bar 207. The detection mechanism 5 on the top detects the surface of the printed matter, and the second printed matter continues to fall onto the surface of the previous one in turn, and the detection mechanism 5 continues to detect, thereby completing the entire inspection process. After the inspection is completed, the stacked printed matter can be directly packaged.
