Technical Field

The invention relates to the field of filtering devices, in particular to motion detection and adjustment of a circulating filter belt of a negative pressure filtering system.

Background

The negative pressure filtering system is widely applied in the machining industry, the size of equipment is about ten meters generally due to the characteristics of centralized treatment and large circulation, and the length of a used circulating filter belt is at least twice of that of the equipment. Therefore, whether the circulating filter belt can normally operate in the system is an important guarantee for the filtering capacity of the system. The motion of the circulating filter belt in the negative pressure filter system box body mainly depends on the friction force between the scraper plate in the box body and the accumulated metal chips to slide on the metal plate between the main box body and the vacuum cavity, and no active power is provided. The other guarantee that it can move smoothly is the self rate of tension of circulating filter belt promptly. The traditional negative pressure filtration system circulating filter belt tensioning mainly depends on a manual tensioning device at the tail of the machine and is not provided with a circulating filter belt movement detection device, and in practical production application, the circulating filter belt can intermittently slip and stop. The negative pressure continues to alarm and other components of the system continue to operate, but the circulating filter belt does not actually move. Intermittent slippage of the endless filter belt is difficult to detect at the production site. In practical application, the negative pressure filtering system is generally responsible for supplying and filtering cutting fluid of several or even dozens of machine tools, and the normal operation of the circulating filter belt is an important guarantee for the normal operation of the machine tools. And the abnormal operation of the circulating filter belt can directly cause the whole liquid using equipment to be shut down.

The tensioning device can detect and adjust the tensioning condition of the circulating filter belt in real time, is simple to operate, does not influence the normal work of other equipment, and avoids the influence of loosening, stacking or slipping of the circulating filter belt on the filtering efficiency and the filtering precision of the equipment.

The circulating filter belt detecting and adjusting device is described below with reference to specific embodiments to further understand the inventive concept of the circulating filter belt detecting and adjusting device.

Referring to fig. 1 and 2, an adjusting device 80 of a circulating filter belt detector is fixed on a housing 10 and comprises a guide roll shaft 20, a connecting plate 30, a connecting shaft 40, a detecting assembly 50 and an adjusting assembly 60. The outer circular surface of the guide roll shaft is coated with a circulating filter belt 70, the connecting shaft 40 is fixed on the inner walls of the two sides of the shell 10, one end of the connecting plate 30 is provided with a through hole matched with the connecting shaft 40 and movably sleeved on the connecting shaft, and the other end of the connecting plate is fixedly connected with the guide roll shaft 20; the guide roll shaft and the connecting shaft are arranged in parallel and movably connected with the shell. Further, the guide roller shaft 20 and the connecting plate 30 can rotate around the connecting shaft 40, and the gravity of the guide roller shaft also has a pressing and tensioning effect on the circulating filter belt 70.

Specifically, the detection assembly 50 is arranged on the connecting plate and located between the connecting shaft 40 and the guide roller shaft 20, and is mainly used for detecting the tension of the circulating filter belt. The adjusting assembly 60 is mounted at one end on the inner wall of the housing 10 and at the other end on the connecting plate 30 near the side of the guide roller shaft 20, and is mainly used for tensioning and adjusting the circulating filter belt.

It should be noted that the connection between the connecting plate 30 and the connecting shaft 40 may adopt a bearing transmission, so that the resistance may be reduced while the connecting plate rotates around the connecting shaft.

Further, referring to fig. 1, the detecting assembly 50 includes a sensor 501 and a detecting piece 502, the detecting piece is fixedly sleeved on one end of the guiding roller shaft 20, and the sensor 501 is matched with the detecting piece and is installed on the connecting plate 30. In one embodiment, the sensor 501 may be a proximity switch, and its end face is disposed at a distance from the detection sheet 502.

Further, in order to accurately detect the operation condition of the guide roller shaft, the detection piece 502 mounted thereon is provided with a plurality of protrusions having the same radius of gyration.

Further, the adjusting assembly 60 includes a driving rotating member 601 and a hanging chain 602, the driving rotating member is fixedly installed on the inner wall of the housing 10, one end of the hanging chain is connected with the driving rotating member 601, and the other end of the hanging chain is fixedly connected with the connecting plate 30. In one embodiment, the driving rotation 601 may be a motor, and the hanging chain 602 may be a chain connected to an output shaft of the motor, and when the motor rotates, the chain is wound around the output shaft. It should be noted that the specific form of the rotary driving member 601 is not limited as long as the rotary driving force can be provided to wind the hoist chain.

In one embodiment, the endless filter belt detection and conditioning device further comprises a control assembly, which includes a time relay, for use with the sensor 501. Specifically, detect the piece according to circulating filter area normal work running speed sets up certain arch, then time relay sets for a check-out time according to detecting the bellied number of piece and rotational speed, and the time that detects the piece when the sensor surpasss the check-out time of settlement, means direction roller stall or intermittent type rotation, just also explains circulating filter area rate of tension problem just this moment, and the sensor just sends abnormal signal this moment, assigns the instruction simultaneously and reaches adjusting device.

Further, the guide roller shaft 20 and the endless filter belt 70 are relatively moved by friction. Specifically, the circulating filter belt is tensioned during normal operation, the guide roller shaft is wrapped inside and tightly presses the circulating filter belt, and when the circulating filter belt is tensioned, the guide roller shaft rotates reversely along with the circulating filter belt.

In one embodiment, referring to fig. 3, in the negative pressure filtration system 1, a manual tensioning device 90 is arranged at the tail, an automatic tensioning device 100 is arranged at the head, and an endless filter belt detecting and adjusting device 80 is arranged in the filter cavity. It should be noted that the reason why the circulating filter belt detecting and adjusting device is arranged in the filter cavity is that when the filter system works normally, the running condition of the circulating filter belt in the filter cavity is not easy to be checked, and the circulating filter belt is not easy to be processed when the circulating filter belt fails or breaks down. The invention can automatically solve the problems when the device is unattended. In operation, the endless filter belt 70 passes through the manual tensioning device, the automatic tensioning device, and the guide rollers of the endless filter belt sensing and adjusting device to form a closed loop. When the circulating filter belt 70 becomes clogged and needs to be renewed after the filter system has been in operation for a period of time, the circulating filter belt begins to operate. Under normal conditions, the circulating filter belt can drive the guide roller shaft 20 to rotate due to the action of friction force during operation, the detection sheet 502 operates normally, and the sensor 501 detects normally. When the sensor 501 detects no signal or the time interval of the detected signal is not consistent with the set detection time, i.e., the guide roller shaft 20 stops rotating or runs intermittently, it indicates that the circulating filter belt runs in a failure. At the same time, the sensor sends out a signal to drive the rotating part 601 to rotate, the hanging chain 602 is wound while rotating, and at the moment, the connecting plate 30 connected to the hanging chain moves towards the tensioning direction of the circulating filter belt and moves along with the guide roller shaft 30 fixed with the connecting plate 30, so that the circulating filter belt is in a tensioning state. At the moment, the detection signal of the sensor returns to normal, and the adjusting device stops acting. After the circulating filter belt is tensioned, the fault of the circulating filter belt in the system is eliminated, so that the automatic monitoring and intelligent adjustment of the running process of the circulating filter belt are realized, the system is ensured to be smoothly carried out in the updating process of the circulating filter belt, and the normal running of the filter system is effectively ensured.

It should be noted that in the filtering system, if the circulating filter belt is long, the circulating filter belt detecting and adjusting device can be provided with a plurality of groups for detecting and adjusting the tightness of the circulating filter belt, so as to ensure the normal operation of the system.

The invention can detect the running condition of the circulating filter belt in real time and can automatically and quickly process the circulating filter belt without stopping the circulating filter belt when the circulating filter belt is abnormal. And through automated inspection and regulation, can effectively tensioning the filter belt, pull when avoiding manual adjustment, cause circulating filter belt to damage, influence its life.
