[0002] In the post-press production process, the printed paper needs to go through a series of subsequent processing, such as cutting, folding, binding, etc. These processing processes require the support of post-press equipment. However, the existing post-press equipment does not establish a communication connection with the front-end printing equipment, resulting in the need for manual measurement and writing of paper dimensions during the post-press processing. Specifically, the operator needs to use a ruler to measure the paper, and then manually input the measured size data into the post-press equipment so that the equipment can adjust the position of the relevant stop gauge according to the input size to complete the post-press processing.

[0003] However, the manual measurement process is cumbersome and has a certain probability of error. When measuring and writing, operators may make mistakes such as misreading or writing the wrong size. These errors will lead to inaccurate adjustment of the stopper position of the post-press equipment, thus affecting the quality and efficiency of post-press processing. Therefore, how to improve the automation level of post-press equipment in dimension measurement and writing and reduce the error rate in manual operation has become an urgent problem to be solved in the current post-press production process.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1 An embodiment of the utility model discloses an automatic paper type detection device, which is used to realize automatic detection of paper type to reduce manual operation. Specifically, the detection device includes:

[0023] A frame 1 having an upper paper baffle 11 and a side paper baffle 12, wherein the upper paper baffle 11 and the side paper baffle 12 are arranged vertically;

[0024] An upper moving member 2 and a side moving member 3 are movably connected to the frame plate 1. The upper moving member 2 and the side moving member 3 are vertically distributed. A coupling mechanism 4 is arranged between the upper moving member 2 and the side moving member 3. The coupling mechanism 4 moves synchronously with the upper moving member 2 and the side moving member 3.

[0025] The frame plate 1 is also provided with a first driving member 5 and a second driving member 6 for driving the upper moving member 2 and the side moving member 3 to move respectively.

[0026] In some embodiments, the upper moving member 2 in the present invention includes a first plate 21 , and a first baffle 22 is fixed to the upper side of the first plate 21 , wherein the first plate 21 slides with the frame plate 1 through a longitudinal guide assembly 23 .

[0027] On the basis of the above-mentioned embodiment, the side moving member 3 in this embodiment includes a second plate 31, the second plate 31 is located below the first plate 21, a second baffle 32 is fixed to the upper end side of the second plate 31, wherein the second plate 31 slides with the frame plate 1 through a lateral guide assembly 33.

[0028] It should be noted that the longitudinal guide assembly 23 and the transverse guide assembly 33 are both configured as guide rail and slider assemblies, and the specific guide rail and slider assemblies include guide rails and sliders. There are two guide rails in each guide assembly, and they are horizontally installed on the frame plate 1 to ensure the stable sliding of the first plate 21 or the second plate 31, wherein the slider is installed on the first plate 21 or the second plate 31, and the specific installation method is a conventional means for technicians in the relevant field, which will not be elaborated here.

[0029] In addition, the connecting mechanism 4 described in this embodiment includes a corner plate 41 arranged above the first plate 21, and a straight groove is opened on the end surfaces of the first plate 21 and the second plate 31. A slide is fixedly installed at the bottom of the corner plate 41, and the slide is slidably connected to the two straight grooves distributed above and below. Preferably, the slide described in this embodiment is preferably set as a rectangular seat to prevent the corner plate 41 from rotating. The design of the corner plate 41 is used to resist the corners of the paper to improve the accuracy of detection. Secondly, the design of the straight groove is used to provide a sliding space for the corner plate 41 to ensure that the corner plate 41 can slide stably.

[0030] In some embodiments, the first driving member 5 in the utility model includes an upper driving wheel 51 and an upper idler wheel 52 rotatably connected to the frame plate 1, and the upper driving wheel 51 and the upper idler wheel 52 are driven by a first driving belt 53. A first servo motor 54 for driving the upper driving wheel 51 to rotate is also fixed on the frame plate 1. Specifically, in this embodiment, the first servo motor 54 can be directly connected to the upper driving wheel 51, or it can be driven by a pulley and a belt transmission mechanism. This method is a conventional method in the field and will not be described in detail here.

[0031] The first plate 21 is connected to the first driving belt 53 via a first pressing plate 55 . Specifically, the upper driving wheel 51 and the upper idler wheel 52 are both configured as pulleys, and the first driving belt 53 is a synchronous belt.

[0032] In addition, the second driving member 6 includes a side driving wheel 61 and a side idler wheel 62 rotatably connected to the frame plate 1, the side driving wheel 61 and the side idler wheel 62 are driven by a second driving belt 63, and a second servo motor 64 for driving the side driving wheel 61 to rotate is also fixed on the frame plate 1, and of course the second servo motor 64 also adopts the above-mentioned driving method;

After connecting to the controller, the position calculation is realized to measure the size of the paper.

[0035] When working, the second servo motor 64 is controlled to rotate counterclockwise, and the second plate 31 moves backward until the second pressure plate 65 moves to the side driving wheel 61. Due to mechanical reasons, the front and rear second pressure plates 65 will be blocked at the side driving wheel 61 and cannot move forward. At this time, the second servo motor 64 will be blocked. The second servo motor 64 can feedback the current state and position to the controller. After receiving the blocking signal, the controller controls the second servo motor 64 to stop running and records the position data at this time.

[0036] The first plate 21 moves in the same principle, so that the first plate 21 moves to the rightmost side. At this time, the device is in the initial position and paper can be placed. When placing the paper, the paper is manually pushed against the upper paper stopper 11 and the side paper stopper 12. After placing, press the start button, and the controller will control the first servo motor 54 and the second servo motor 64 to rotate, thereby controlling the first plate 21 to move upward and the second plate 31 to move leftward; when the second baffle 32 and the corner plate 41 of the second plate 31 touch the tail of the paper, the second plate 31 cannot move forward, and the second servo motor 64 is blocked at this time. The second servo motor 64 feeds back the current state and position to the controller. After receiving the signal, the controller controls the second servo motor 64 to stop running, and calculates the current position with the initial position, and outputs the calculation result, which is the paper length;

[0037] When the first baffle 22 and the corner plate 41 on the first plate 21 touch the right side of the paper, the first plate 21 cannot move forward. At this time, the first servo motor 54 is blocked. The first servo motor 54 feeds back the current state and position to the controller. After receiving the signal, the controller controls the first servo motor 54 to stop running, and calculates the current position with the initial position, and outputs the calculation result, which is the paper width.
