[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-3 As shown, this utility model is a counting structure for a printing press, comprising:

[0028] Counting machine 11;

[0029] The internal components of the counting machine 11 include an infrared sensor, a microcontroller counting module, an LED display module, and a PLC control module. When printed materials pass under the infrared sensor, the infrared rays emitted by the sensor are blocked by the printed materials. The infrared sensor generates an electrical signal, which is transmitted to the microcontroller counting module through a shielded wire. After receiving the signal, the microcontroller counting module increments the count by one and then transmits the count result to the PLC control module through the shielded wire. The PLC control module then sends the count result to the LED display module, which displays the result for the operator to view.

[0030] The adjustment component includes a side plate 22, a motor 23, a turntable 24, a lead screw 25, a nut ring 26, and a fixing plate 27. The turntable 24 is disposed on one side of the outer surface of the side plate 22. The lead screw 25 is rotatably connected between the two turntables 24. The nut ring 26 is threadedly connected to the outer surface of the lead screw 25. The fixing plate 27 is fixed to one end of the nut ring 26. The counter 11 is installed on the outer end of the fixing plate 27. The motor 23 is fixedly connected to the other side of the outer surface of the side plate 22.

[0031] The turntable 24 and lead screw 25 are driven to rotate by motor 23, which in turn drives the nut ring 26 and the fixed plate 27 connected to it and the counter 11 to move left and right. The position of the counter 11 can be adjusted according to the actual size of the printed paper, so that the counter 11 is always in the most suitable position for detecting the current paper. This effectively avoids omissions or miscounts caused by changes in paper size, greatly improves the accuracy of counting, and provides a reliable guarantee for production data statistics and quality control.

[0032] The fixed plate 27 has a positioning hole 28 inside, and a positioning rod 29 is fixedly connected to one end of the outer surface of the counter 11. The positioning rod 29 is inserted into the positioning hole 28.

[0033] The positioning rod 29 is inserted into the positioning hole 28. This operation serves as a preliminary positioning function to ensure the accuracy of the spatial position of the relevant components.

[0034] A retaining ring 291 is threadedly connected to the lower part of the outer surface of the positioning rod 29, and the retaining ring 291 is tightly attached to the bottom of the fixing plate 27;

[0035] The retaining ring 291 is fastened to the lower part of the outer surface of the positioning rod 29 by threads. The threaded connection securely fixes the inserted positioning rod 29, preventing it from shifting or shaking during equipment operation and ensuring the stability of the overall structure.

[0036] A support plate 21 is welded to one end of the outer surface of the side plate 22;

[0037] The support plate 21 serves as the load-bearing foundation for the entire device and is installed on the outside of the printing press, providing a stable support platform for the subsequent installation and operation of various components.

[0038] Working principle:

[0039] First, the support plate 21 is installed on the outside of the printing press. Then, the positioning rod 29 is inserted into the positioning hole 28. Subsequently, the fixing ring 291 is fastened to the lower part of the outer surface of the positioning rod 29 by threads. The positioning rod 29 is firmly fixed after insertion by the tightness of the threaded connection. Then, the motor 23 is started to drive the turntable 24 and the lead screw 25 to rotate. The nut ring 26 can move left and right according to the rotation of the lead screw 25, and the counter 11 connected to it moves at the same time.

[0040] This step, through the lead screw 25 nut transmission structure driven by motor 23, can achieve high-precision position control, effectively improving the accuracy of equipment adjustment in printing technology and ensuring the stability and efficiency of the printing process.

[0041] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0042] The locking component includes a locking ring 33, a support rod 35, and a support frame 37. The support rod 35 is fixed between multiple locking rings 33, and the support frame 37 is fixed on the outer side of the two locking rings 33. The locking rings 33 are sleeved on the outer surface of the fixing ring 291.

[0043] After the fixing ring 291 is fixed to the lower part of the outer surface of the positioning rod 29, the support frame 37 can be lifted upwards, so that the locking ring 33 is locked to the outside of the fixing ring 291, which can prevent the fixing ring 291 from becoming loose later.

[0044] The fixed plate 27 has guide grooves 31 on both sides, and a guide block 34 is fixedly connected to the upper part of one side of the support frame 37. The guide block 34 is movably connected inside the guide groove 31.

[0045] The guide block 34 slides inside the guide groove 31, which can drive the locking ring 33 to move up and down.

[0046] A slot 32 is provided at the top of the inner surface of the guide groove 31, and a locking block 36 is provided at the top of the guide block 34. The locking block 36 is engaged inside the slot 32.

[0047] By moving the guide block 34 inside the guide groove 31, the locking ring 33 is moved to the upper part. After the locking ring 33 is locked outside the fixed ring 291, the locking block 36 is simultaneously engaged inside the locking groove 32 to fix the position of the locking ring 33.

[0048] Working principle:

[0049] First, when a locking operation is required, the sliding of the guide block 34 inside the guide groove 31 causes the locking ring 33 to move stably to the upper position along the guide direction. After the locking ring 33 moves to the designated upper position, the locking ring 33 is locked to the outside of the fixed ring 291. The locking block 36 set on the locking ring 33 will be simultaneously engaged in the corresponding slot 32.

[0050] This step can reliably and stably fix the position of the locking ring 33, preventing it from loosening or shifting during equipment operation, thereby ensuring the working stability and safety of the entire device.
