Of course, the number of the tooth blocks 16 can also be multiple, for example, in the case that there are three tooth blocks 16, the difference of the central angles between every two tooth blocks 16 is 120 degrees, so as to ensure that the toothed plate 7 is driven by the rotating shaft 3 to slide at a constant speed.
Considering that the power transmission mechanism needs a larger amount of lubricating oil and a more comprehensive lubricating effect under the condition of high-speed movement, in order to further solve the technical problem that the conventional belt-type power transmission mechanism may not be capable of adjusting the lubricating effect according to the rotating speed of the transmission, as shown in fig. 1-2, the invention further designs a jacking device 14 below the conveyor belt 13, wherein the jacking device 14 is used for jacking the conveyor belt 13 in the vertical direction, at the moment, because the conveyor belt 13 is positioned between the jacking device 14 and the wheels 4, the jacking device 14 can lift the wheels 4 and the conveyor belt 13 by micro-displacement to make partial or comprehensive contact, so that the size of the friction surface between the wheels 4 and the conveyor belt 13 is adjusted by the jacking device 14, a sensor 15 is arranged in the jacking device 14, and the sensor 15 is used for detecting the speed of the conveyor belt, the lift device 14 is moved up and down by the induction of the inductor 15.
For example: when the conveyer belt is slowed down when moving, the jacking device slowly descends, and the friction surface between wheel 4 and the conveyer belt 13 reduces, makes wheel 4 can automatic underspeed when 13 slowed down movements of conveyer belt for the opening effect of pinion rack 7 to through-hole 10 weakens, has reduced the total oil volume of the lubricating oil of through-hole 10 totality whereabouts, thereby controls the flow of lubricating oil, has saved unnecessary lubricating oil consumption. In the case of zero friction between the wheel 4 and the conveyor belt 13 (i.e. when the lifting device is lowered without lifting the conveyor belt 13), the cogged plate 7 can be returned by a spring to a minimum of 3 through holes as shown in fig. 3 or even to close all through holes, so that the conveyor belt consumes a minimum amount of oil at low speed or at rest, and lubrication is only performed in critical areas.
In addition, at the middle and high rotating speed, the contact area between the wheel 4 and the conveyor belt 13 is controlled to be increased by the lifting device to lift, the gear tooth plate 7 is almost continuously positioned at the leftmost side, the spring 9 is in the maximum compression state, and in order to ensure that the conveyor belt can fall through different numbers of through holes 10 to ensure enough lubricating oil when the conveyor belt runs at the middle speed or the high speed, the length of the spring 9 and the number and the positions of the through holes 10 can be set according to the conditions. For example, when the total number of the through holes 10 is 9, the number of the through holes 10 to be conducted is 9 when the spring 9 is compressed at the maximum at a high rotation speed; when the rotating speed is medium and the spring 9 is properly compressed, the number of the through holes 10 which are communicated is 6; when the rotating speed is low and the spring 9 is freely reset, the number of the through holes 10 which are conducted is 3 or 0.
In another embodiment, the jacking device 14 is preferably an oil press or a buoyancy device, i.e. a controllable lifting device with a connecting rod and a jacking plate driven by oil pressure or oil buoyancy. The sensor 15 for measuring the speed can be a laser sensor, which is a conventional product and thus is not explained. In addition, the outer side of the jacking device 15 can be provided with a connecting rod 12, so that the jacking device 15 can be installed and fixed.
It is worth mentioning that the jacking device of the invention belongs to a better design, and the design of the jacking device can better ensure that the lubricating device does not influence the normal movement of the conveyor belt or cause the resistance of the lifting speed when the conveyor belt is static or runs at a low speed, and does not influence the working efficiency of the belt type power transmission mechanism, but does not belong to a necessary part in the lubricating device. In a special case (for example, when it is inconvenient to install the jacking device under the conveyor), the connecting rod 12 can be controlled to drive the whole device housing 1 to move up and down, or the rotating shaft 3, the wheel 4 and other components in the device housing 1 can be controlled to move up and down, so that the contact area and the vertical distance between the wheel and the conveyor belt can be adjusted. In addition, in extreme cases, the device housing 1 and the conveyor belt 13 which are not fixed can be designed to be always in contact with each other in the whole process, so that the opening degree of the through hole and the oil quantity of the falling lubricating oil can be adjusted only through the speed of the conveyor belt, but the normal movement of the conveyor belt is influenced or the resistance of the rising speed of the conveyor belt is caused, and the power efficiency of the whole device is reduced.
For a better understanding of the lubricating apparatus of the present invention and its advantages, the following detailed description will be made of the respective working modes and principles of the unpowered apparatus part in the apparatus housing 1 above the conveyor belt 13 and the jacking apparatus 14 below the conveyor belt 13:
(A) working mode of unpowered device part above conveyor belt
The first step is as follows: referring to fig. 1-5, when the belt-type power transmission mechanism starts to work, the belt 13 rotates, so that the wheel 4 connected to the belt 13 rotates, the rotation of the wheel 4 rotates the rotating shaft 3 for fixing the wheel 4, and the rotation of the rotating shaft 3 rotates the disc 5;
the second step is that: due to the rotation of the disc 5, the toothed block 16 fixed on the disc 5 will rotate, so that the gear 6 will rotate, and the rotation of the gear 6 will push the toothed plate 7 to move horizontally on the sliding rail 8, so that part or all of the through holes 10 are opened;
the third step: with the opening of the through hole 10, the lubricating oil flows into the spray head 11, so that the spray head 11 lubricates the lower wear designated part with the lubricating oil, and finally spraying is finished, and the gear 6 has no power for a period of time because only two gear blocks 16 exist, and at the moment, the gear is pushed back by the spring 9 to block the through hole 10, so that spraying and stopping of the lubricating oil on other designated positions are finished.
(B) Working mode of jacking device below conveying belt
In order to better illustrate the advantages of the jacking device working together with the above lubricating device, the working principle of the lubricating device during acceleration and deceleration will be described below with reference to fig. 1-5, and the number of the through holes in the oil collecting tank is set to be 9, and the oil collecting tank is set to be a nine-grid (only 6 through holes are listed in fig. 1-5):
first step (conveyor speed detection): when the belt type power transmission mechanism starts to change speed after the lubricating device of the belt type power transmission mechanism starts to work, the sensor 15 obtains speed information by sensing the speed change condition of the belt type power transmission mechanism; the speed of a conveyor belt in the power transmission mechanism is divided into a low speed, a medium speed and a high speed by automatically setting a threshold value;
second step (acceleration process-low speed): when the speed of the power transmission mechanism is low, the sensor 15 controls the jacking device 14 to descend to a position where the conveying belt 13 is not jacked through the controller, or controls the jacking device 14 to continuously keep low, so that the conveying belt 13 is not in contact with the wheels 4 at low speed, and at the moment, if a small amount of specified positions need to be lubricated, the length of the free end when the spring 9 is reset can be set to enable the toothed plate 7 not to shield the 3 through holes 10 at the rightmost end, so that the minimum lubricating effect is guaranteed; at this time, if no lubrication is needed, the free end length when the spring 9 is reset can be set to enable the pinion plate 7 to block and cover all the through holes 10;
third step (acceleration process-medium-high speed): when the speed of the power transmission mechanism is at a medium speed or a high speed, the sensor 15 controls the jacking device 14 through the controller to enable the jacking device 14 to jack upwards, so that the contact surface between the wheel 4 and the conveyor belt 13 is increased according to the speed ratio or the speed range (for example, the conveyor belt and the wheel start to contact at the medium speed, part of the positions start to lubricate at the time, the contact area between the conveyor belt and the wheel is increased at the high speed, fixed-point fixed-time fixed-quantity lubrication is started at a plurality of positions at the high speed, the rotating speed of the wheel 4 is slowly increased, the wheel 7 moves leftwards, the opening number of the toothed plates of the through holes 10 is increased, and the falling oil quantity is finally increased, for example, 3-9 through holes 10 can be opened at the speed ratio when the conveyor belt 13 runs at the medium speed and the high speed through reasonable setting; the deceleration process of the conveyor belt at medium to high speeds is the opposite of the above acceleration process, and is not cumbersome here.
Fourth step (deceleration process-low speed): when the speed of belt power transmission mechanism reduces to low-speed or stops from the intermediate speed, inductor 15 can drive jacking device 14 through the controller and descend, drives conveyer belt 13 and carries out the displacement decline to finally make conveyer belt 13 and wheel 4 break away from completely, can keep the lubrication of 3 through-holes 10 as required this moment or close whole through-holes 10, thereby guarantee minimum lubricated oil mass under the condition that does not influence belt power transmission mechanism operating efficiency.
