Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of roller presses, and more particularly to a roller press monitoring system. BACKGROUND

[0002] At present, many companies in the ceramic industry pay attention to energy saving and consumption reduction in raw material processing, and are equipped with raw material pre-processing crushing systems. The sand and stone materials before entering the ball mill are crushed to below 3mm, and then ground in the ball mill to achieve the purpose of energy saving. In the crushing equipment aspect, large-scale roller press crushing machines (referred to as roller presses) are mostly selected due to high yield and crushing efficiency.

[0003] The working principle of the roller press is as follows: the motor transmits power to the speed reducer through the universal transmission shaft, the speed reducer reduces the speed and increases the torque, and then the kinetic energy is output to the roller system (main and auxiliary rollers) through the output shaft of the speed reducer, and the roller system (main and auxiliary rollers) is connected to the driving speed reducer box in an arch-shaped expansion sleeve locking disc connection mode.

[0004] This connection mode is mainly used for transmitting torque of heavy load large equipment, especially the equipment whose weight borne by the speed reducer (box) is on the output torque. The advantage of this connection mode is that it is easy to disassemble, and it can protect the speed reducer gear from overloading when the roller system is running for a long time and the expansion sleeve of the output shaft of the speed reducer is connected to the input shaft of the roller system slips to protect the speed reducer gear from being damaged by overloading.

[0005] However, if the expansion connection is not checked and found loose in time, the input shaft and the sleeve may slip during operation, the expansion sleeve of the output shaft of the speed reducer and the roller shaft are connected for a long time, the roller shaft head and the expansion sleeve hole in the speed reducer output shaft sleeve will be dry ground, resulting in the shaft head being ground small and the expansion sleeve hole being ground large, so that the speed reducer output shaft sleeve and the roller shaft head cannot be tightly matched, causing a major damage accident of the equipment.

[0006] The repair work of the expansion sleeve of the output shaft of the speed reducer and the roller shaft head is time-consuming and labor-intensive, and the repair cost is high. The roller press needs to be disassembled and the roller system (a single roller weighs 10t) needs to be removed by a large crane, the large bearing needs to be disassembled, the roller system shaft head needs to be processed and repaired in a large-scale machine tool, and the expansion sleeve of the output shaft of the speed reducer needs to be disassembled and removed by a large crane, the internal gear of the entire speed reducer box needs to be disassembled, the expansion sleeve of the output planetary carrier of the speed reducer box needs to be disassembled, the internal hole needs to be repaired, and then the size of the processing matching surface needs to be processed on a lathe. After the processing is completed, the speed reducer is assembled and restored. The entire disassembly and repair process requires multiple large lifting equipment, and the entire repair process takes nearly a month. The repair cost is particularly high (up to nearly one hundred thousand yuan), causing huge economic losses of the damaged equipment, affecting normal production and enterprise production efficiency.

[0007] Therefore, the prior art needs to be improved. Invention content

[0069] Please refer to Figure 1 and Figure 2The embodiment provides a roll press monitoring system for monitoring a roll press, the roll press comprising a roll system mechanism 100 and a transmission mechanism 200 in transmission connection with the roll system mechanism 100, wherein the roll press monitoring system comprises a PLC logic controller 300, a first monitoring device 400 and a second monitoring device 500, the PLC logic controller 300 is in electrical connection with the roll press, the first monitoring device 400 is in electrical connection with the PLC logic controller 300, the first monitoring device 400 is installed on the roll system mechanism 100, the first monitoring device 400 is used for monitoring the operation of the roll system mechanism 100, the second monitoring device 500 is in electrical connection with the PLC logic controller 300, the second monitoring device 500 is installed on the transmission mechanism 200, and the second monitoring device 500 is used for monitoring the operation of the transmission mechanism 200.

[0070] In the embodiment, the roll press comprises the roll system mechanism 100 and the transmission mechanism 200, the transmission mechanism 200 is used for driving the roll system mechanism 100 to operate, the first monitoring device 400 can monitor the operation of the roll system mechanism 100 and acquire a first signal, the first monitoring device 400 can send the first signal to the PLC logic controller 300, the second monitoring device 500 can monitor the operation of the transmission mechanism 200 and acquire a second signal, the second monitoring device 500 can send the second signal to the PLC logic controller 300, and the PLC logic controller 300 can compare and analyze the first signal and the second signal, when the first signal and the second signal appear out-of-position asynchronous sensing signals, it can be identified as a fault, and the fault is that the transmission mechanism 200 and the roll system mechanism 100 slip, displace or loosen.

[0071] For example, the roller press includes a frame, a roller system mechanism 100, a transmission mechanism 200, and a driving mechanism 800. The roller system mechanism 100 is composed of two rollers rotating at equal speed and relatively slow speed, one of which is fixed and the other of which can move in the horizontal direction to control the gap between the two rollers, and the material is crushed by high pressure through opposite rotation. The transmission system is mainly composed of a speed reducer, a hydraulic coupling, a universal coupling, a shrink sleeve coupling, a lubricating device and the like. The driving mechanism 800 is composed of an electric motor. These components work together to provide the necessary power for the roller system mechanism 100 and ensure its stable operation. When the connection between the roller system mechanism 100 and the transmission mechanism 200 is loose, overloaded and slips, the first monitoring device 400 and the second monitoring device 500 will deviate from the synchronous induction, that is, the misalignment induction. When the PLC logic controller 300 recognizes that the first monitoring device 400 and the second monitoring device 500 have misalignment induction, the PLC logic controller 300 can recognize that the connection between the roller system mechanism 100 and the transmission mechanism 200 has failed, and can automatically stop in time to avoid continuous triggering of serious equipment accidents; avoid the expansion of the area of equipment accidents such as blocking of the conveying belt in front of the roller press, damage of the conveying belt caused by blocking of the belt, and the like; effectively monitor the point position state of the roller press, and accumulate fault records to facilitate tracing and analyzing the operation of the roller press equipment.

[0072] Therefore, the PLC logic controller 300 in the embodiment can recognize that the connection between the roller system mechanism 100 and the transmission mechanism 200 has failed, can automatically stop in time to avoid continuous triggering of serious equipment accidents; avoid the expansion of the area of equipment accidents such as blocking of the conveying belt in front of the roller press, damage of the conveying belt caused by blocking of the belt, and the like; effectively monitor the point position state of the roller press, and accumulate fault records to facilitate tracing and analyzing the operation of the roller press equipment.

[0073] Specifically, please refer to Figure 3 and Figure 4 , the roller system mechanism 100 includes a first compression roller 110 and a second compression roller 120. The first compression roller 110 includes a first roller body and a first rotating shaft 111 connected with the first roller body.

[0075] In the embodiment, the roller system mechanism 100 is composed of two extrusion rollers rotating in the same direction, for example, the first pressure roller 110 can be a fixed roller, and the second pressure roller 120 can be a movable roller. The first pressure roller 110 can include a first roller body and a first rotating shaft 111, and the first rotating shaft 111 is used for driving connection with the transmission mechanism 200. The second pressure roller 120 can include a second roller body and a second rotating shaft 121, and the second rotating shaft 121 is used for driving connection with the transmission mechanism 200.

[0076] The first monitoring device 400 includes a first photoelectric sensor 410 and a second photoelectric sensor 420, that is, the first monitoring device 400 is made of photoelectric sensors, which use the photoelectric conversion principle to convert the change of the optical signal into the change of the electrical signal to realize control. For example, the photoelectric sensor can include a light emitter and a light receiver, and in use, taking the first pressure roller 110 as an example, the detection head is installed with the light emitter and the light receiver, and the detection head is located on the side of the first rotating shaft 111. When the first rotating shaft 111 drives the inductor to rotate, the inductor on the first rotating shaft 111 can block the light path and reflect the light path back every rotation, and the light receiver receives the optical signal and outputs an inductive signal. Similarly, taking the second pressure roller 120 as an example, the detection head is located on the side of the second rotating shaft 121. When the second rotating shaft 121 drives the light receiver to rotate, the inductor on the first rotating shaft 111 can block the light path and reflect the light path back every rotation, and the light receiver receives the optical signal and outputs an inductive signal.

[0079] In the embodiment, the transmission mechanism 200 includes a first speed reducer, a first output shaft sleeve 210, a second speed reducer, and a second output shaft sleeve 220. The first speed reducer is drivingly connected with the roller system mechanism 100 through the first output shaft sleeve 210, specifically, the first speed reducer is drivingly connected with the first rotating shaft 111 through the first output shaft sleeve 210.

The first photoelectric sensor 410 and the third photoelectric sensor 510 form a group, and the second photoelectric sensor 420 and the fourth photoelectric sensor 520 form a group. That is, the first photoelectric sensor 410 and the third photoelectric sensor 510 synchronously sense, and the second photoelectric sensor 420 and the fourth photoelectric sensor 520 synchronously sense. If the first photoelectric sensor 410 and the third photoelectric sensor 510 appear dislocation sensing, the first rotating shaft 111 and the first output shaft sleeve 210 appear slip or displacement or connection loosening failure; if the second photoelectric sensor 420 and the fourth photoelectric sensor 520 appear dislocation sensing, the second rotating shaft 121 and the second output shaft sleeve 220 appear slip or displacement or connection loosening failure.

[0081] Specifically, please refer to Figure 2 The third photoelectric sensor 510 and the first photoelectric sensor 410 are located on the same horizontal line, and the second photoelectric sensor 420 and the fourth photoelectric sensor 520 are located on the same horizontal line.
