Description

Technical Field

[0001] This utility model relates to the field of paper feeding technology in printing presses, and in particular to a speed detection structure for a paper feeding transmission system. Background Technology

[0002] In the corrugated cardboard printing process, several drive shafts are typically arranged horizontally on the frame to drive the cardboard. During the operation of the paper feeding section, the rotational speed of the entire section needs to be kept consistent. Currently, the paper feeding section includes two opposing drive shafts and a synchronous shaft, as well as a paper feeding roller for conveying paper. To ensure feeding accuracy, the overall machine speed and the paper feeding roller speed should be kept as close as possible. The conventional approach is to use separate servo motors to drive the entire machine and the paper feeding roller, setting the same parameters in the servo system to ensure accurate paper feeding. However, because two separate servo motor systems drive the entire machine and the paper feeding roller, a speed difference is inevitable. Therefore, a new technology is urgently needed to solve the aforementioned technical problems. Utility Model Content

[0003] The purpose of this invention is to provide a speed detection structure for a paper feeding transmission system to solve the above-mentioned technical problems.

[0007] Synchronous shaft, which is rotatably connected to the frame plate in parallel with the drive shaft;

[0008] A transmission structure is mounted on the frame plate and connected to the drive shaft and the synchronous shaft at both ends, respectively.

[0009] A speed detection device is connected to the main controller and records the speed signals of the drive shaft and the paper feeding unit, respectively, and transmits the speed signals of the drive shaft and the paper feeding unit to the main controller.

[0010] Furthermore, the rotational speed detection device includes:

[0011] A mounting base is fixedly installed on the frame plate;

[0012] The detection shaft is rotatably connected to the fixed base, which is parallel to the synchronous shaft, and is also connected to the synchronous shaft in a transmission manner.

[0014] The second encoder is fixedly mounted on the fixed base, and its input end is connected to the other end of the detection shaft. The second encoder is used to input the predetermined conveying speed of the paper feeding unit.

[0015] Furthermore, the fixed base includes a base plate fixedly installed on the frame plate. The base plate is connected to a first plate and a second plate at intervals by a number of support rods. The first plate and the second plate are spaced apart by the support rods. The two ends of the detection shaft are rotatably connected to the first plate and the second plate, respectively.

[0016] Furthermore, a synchronous pulley is fixedly mounted on the detection shaft, and the synchronous pulley is connected to the synchronous shaft via a synchronous belt.

[0017] Furthermore, two spacers are provided on the detection shaft, with the two spacers located on both sides of the synchronous pulley, and simultaneously limiting the synchronous pulley along the axial direction of the detection shaft.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] During the operation of the paper feeding section, the drive shaft and the paper feeding roller are driven separately. The same speed parameters are preset on the main controller for the drive device and the paper feeding servo motor. The speed detection device records the above speed parameters and simultaneously measures the movement speed of the whole machine.

By detecting the actual speed of the whole machine and comparing it with the set parameters, it is possible to quickly detect whether the speed of the paper feeding unit and the drive shaft are consistent.

It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] This utility model embodiment provides a speed detection structure for a paper feeding unit transmission system. During the operation of the paper feeding unit, the operating parameters of the paper feeding servo motor 22 of the paper feeding unit 20 are set to be the same as the operating parameters of the drive device of the main shaft of the whole machine. At the same time, the speed parameters of the main shaft and the paper feeding unit 20 are recorded by the speed detection device 40. The speed detection device 40 also detects the actual speed information of the main shaft and compares it with the preset and recorded speed parameters to detect whether the speed of the main shaft and the paper feeding unit 20 are consistent, so that the operator can adjust the paper feeding unit.

[0030] Specifically, such as Figure 1-4As shown in the figure, the present invention provides a speed detection structure for a paper feeding transmission system, including two opposing frame plates 10, a drive shaft (not shown) rotatably connected to the frame plates 10, a drive device (not shown) connected to the drive shaft, and a main controller (not shown) connected to the drive device. It also includes a paper feeding unit 20, a synchronous shaft 30, a transmission structure (not shown), and a speed detection device 40. The paper feeding unit 20 includes two opposing paper feeding rollers 21 and a paper feeding servo motor 22 that drives the paper feeding rollers 21. The synchronous shaft 30 is rotatably connected to the drive shaft on the frame plates 10, and the transmission structure is mounted on the frame plates 10, with its two ends connected to the drive shaft and the synchronous shaft 30, respectively. The speed detection device 40 is connected to the main controller and records the speed signals of the drive shaft and the paper feeding unit 20, respectively, and transmits these speed signals to the main controller.

[0031] During the operation of the paper feeding section, the drive shaft and the paper feeding roller 21 are driven respectively, and the same speed parameters are preset on the main controller for the drive device and the paper feeding servo motor 22. The speed detection device 40 records the above speed parameters and simultaneously measures the movement speed of the whole machine. The main controller compares the measured speed of the main machine with the set running speed to determine whether the movement speed of the drive shaft and the paper feeding unit 20 are consistent, so as to facilitate the operator to make adjustments.

[0032] The technical solution provided by this utility model can actually detect the speed of the whole machine. By detecting the actual speed of the whole machine and comparing it with the set parameters, it is possible to quickly detect whether the speed of the paper feeding unit 20 and the drive shaft are consistent. This facilitates automated machine adjustment in the main controller and reduces the labor intensity of machine adjustment.

[0033] In this embodiment, the speed detection device 40 includes a fixed base 410, a detection shaft 420, and two encoders. Specifically, the fixed base 410 is fixedly mounted on the frame plate 10; the detection shaft 420 and the synchronous shaft 30 are rotatably connected side by side on the fixed base 410 and are drivenly connected to the synchronous shaft 30; the first encoder 421 is fixedly mounted on the fixed base 410, and its input end is drivenly connected to one end of the detection shaft 420, and the first encoder 421 is used to input the predetermined speed of the drive shaft; the second encoder 422 is fixedly mounted on the fixed base 410, and the input end of the second encoder 422 is drivenly connected to the other end of the detection shaft 420, and the second encoder 422 is used to input the predetermined conveying speed of the paper feeding unit 20.

[0034] In this embodiment, to improve stability during the detection process, the mounting base 410 includes a base plate 411 fixedly mounted on the frame plate 10. The base plate 411 is connected at intervals to a first plate 412 and a second plate 413 via several support rods 414. The first plate 412 and the second plate 413 are spaced apart by the support rods 414. The two ends of the detection shaft 420 are rotatably connected to the first plate 412 and the second plate 413, respectively. By rotatably positioning the detection shaft 420 between the first plate 412 and the second plate 413, and by fixing the first plate 412 and the second plate 413 to the base plate 411 via the support rods 414, mounting positions for the first encoder 421 and the second encoder 422 are provided, while maintaining the stability of the detection shaft 420.

[0035] In this embodiment, to ensure the synchronous rotation speed of the detection shaft 420 and the synchronous shaft 30, a synchronous pulley 415 is fixedly installed on the detection shaft 420, and the synchronous pulley 415 is connected to the synchronous shaft 30 through a synchronous belt 416.

[0036] In this embodiment, in order to further maintain the accuracy of the detection, if the synchronous pulley 415 vibrates or shakes, affecting the detection effect, two spacers 423 are still provided on the detection shaft 420. The two spacers 423 are located on both sides of the synchronous pulley 415, and simultaneously limit the synchronous pulley 415 along the axial direction of the detection shaft 420.

[0037] For those skilled in the art, various other corresponding changes and modifications can be obtained based on the structure and principles disclosed in this utility model, and all such changes and modifications fall within the protection scope of this utility model.
