[0027] The adjusting assembly includes a screw 31, an adjusting nut 32 and a locking nut 33. The lower end of the screw 31 is threadedly connected to the slider 20, and the upper end passes through the fixing seat 11 and is screwed with the adjusting nut 32 and the locking nut 33. A buffer spring is sleeved on the screw 31, and the buffer spring is located between the detection seat 19 and the inner top surface of the fixing seat 11. The design of the adjusting assembly at the upper end of the slider allows the detection device 1 to adjust the upper and lower positions of the touch element 12 before detection, so that the contact point 151 of the touch element 12 and the touch rod 15 on the movable plate 13 is in the trigger position, so as to meet the use requirements of paper of different thicknesses and improve the contact effect of the touch element 12.

[0028] A second fixing plate 121 is installed on the detection seat 19, and a spring 4 is provided between the second fixing plate 121 and the trigger rod 15. The design of the spring 4 between the second fixing plate 121 and the trigger rod 15 can make the paper have a buffering effect when it is transported and detected in the paper passage 16, so as to improve the detection effect of the trigger element 12; a limiting bolt 18 is provided on one side of the trigger rod 15, and the limiting bolt 18 is screwed on the detection seat 19. The design of the limiting bolt 18 can limit the position of the trigger rod 15, effectively preventing the spring 4 from rebounding and causing the trigger rod 15 to rotate and cause detection errors.

The design of the movable plate 13, the trigger rod 15 and the contact 151 on the movable plate 13, the guide plate 14 and the paper passage 16 in the above-mentioned detection device 1 can effectively control the paper thickness of the feeding paper, and at the same time The number of sheets of paper can also be effectively controlled. When the paper thickness exceeds the set paper thickness, the paper cannot pass through the paper passage 16, which pushes the movable plate 13 to rotate, so as to drive the trigger rod 15 and the contact 151 on the trigger rod 15 to rotate to trigger the trigger element 12. The trigger element 12 sends a signal to the control unit of the gluing device. The control unit controls the device to pause and notifies the personnel to handle the problem, so as to improve the automatic operation effect of the gluing device and effectively solve the problem that the book signatures or sheets are easily overlapped during paper feeding, resulting in defective books and huge losses in serious cases.

[0031] The height of the paper passage 16 is greater than or equal to the thickness of a single sheet of paper, and less than the thickness of two sheets of paper. The limited design of the height of the paper passage 16 can screen the overlapping paper that exceeds the thickness of a single sheet of paper, so as to avoid the problem of defective books caused by the overlapping paper entering the next process;

[0032] The mounting assembly 2 includes two fixing rods 21 and a first fixing plate 22 . The two fixing rods 21 are arranged vertically and spaced apart between the first fixing plate 22 and the fixing seat 11 . The first fixing plate 22 and the fixing seat 11 are fixed by bolts to fix the two fixing rods 21 .

[0033] A paper feed mechanism is fixed on the two fixing rods 21 , and a conveying channel is formed between the bottom of the paper feed mechanism and the frame. The conveying channel is located on one side of the paper feeding channel 16 , and the center lines of the conveying channel and the paper feeding channel are on the same axis.

A through slot is provided on the fixed seat 11 for the pin 17 to move up and down, which is used to adjust the upper and lower heights of the movable plate 13. After being adjusted to a specified position, it is locked by a limiter. The height of the paper passage 16 between the movable plate 13 and the guide plate 14 and the rotatable connection between the pin 17 and the slider 20 enable the movable plate 13 to be moved up and down by the slider 20 to adjust the upper and lower heights of the movable plate 13, so as to adjust the height of the paper passage 16 between the movable plate 13 and the guide plate 14, so that it can be suitable for the use requirements of different paper thicknesses, and the number of sheets of paper can be effectively controlled to improve the quality of books.

[0035] The workflow of this utility model:

[0036] When adjusting the detection device: install the fixed seat 11 on the frame through the installation component 2, place the detection seat 19 in the fixed seat 11, install the slider 20 in the slide rail on the detection seat 19, the lower end of the screw 31 passes through the top of the fixed seat 11 and is screwed with the slider 20, and the adjustment nut 32 and the lock nut 33 are screwed on the upper end of the screw 31, the guide plate 14 is installed on the fixed plate 23 of the frame by bolts, the trigger rod 15 is fixed to the movable plate 13 by bolts, the pin 17 passes through the movable plate 13, and the end of the pin 17 passes through the through hole 201 on the slider 20 Then, the movable plate 13 is locked by the stopper, and a certain gap is reserved at the same time so that the movable plate 13 can rotate. The adjusting nut 32 is screwed on the screw rod 31 to adjust the upper and lower positions of the slider 20, so as to adjust the height of the paper passage 16 between the movable plate 13 and the guide plate 14, so that the height is higher than the thickness of a single sheet of paper and lower than the thickness of a double sheet of paper, and at the same time, the trigger point on the touch element 12 and the contact point 151 on the touch rod 15 are ensured to be at the same height. Then, the spring 4 is installed between the second fixing plate 121 and the touch rod 15, and the stop bolt 18 is screwed to the right side of the touch rod 15, and the installation is completed.

[0037] When testing the paper;

[0038] When a single sheet of paper enters from the conveying passage between the paper feeding mechanism and the frame and is conveyed to the paper passing passage 16, the paper is directly conveyed from the paper passing passage 16 to the next process;

[0039] When two sheets of paper enter from the conveying channel between the paper feeding mechanism and the frame and are conveyed to the paper passing channel 16, the paper cannot pass through the paper passing channel 16 and contacts the second arc-shaped contact surface 132 of the movable plate 13. The thrust of the paper feeding mechanism pushes the paper to continue to be conveyed, which pushes the movable plate 13 to rotate, and the trigger rod 15 rotates accordingly. Under the elastic action of the spring 4, the trigger rod 15 drives the contact 151 to trigger the trigger element 12. The trigger element 12 sends a signal to the control unit of the sheet-wrapping and gluing device, and the control unit sends a warning instruction to remind personnel to handle it to avoid the generation of defective products.
