[0002] Poor lubrication of mechanical equipment can cause many adverse effects and hazards;

[0003] First, poor lubrication will aggravate equipment wear, because insufficient lubrication will increase the friction coefficient of the equipment, thereby generating excessive friction heat during operation, which will further accelerate the wear of equipment parts. This wear will not only lead to a decline in equipment performance and work efficiency, but in severe cases may also cause equipment failure, causing serious impact on production;

[0004] Secondly, equipment with long-term poor lubrication will face the problem of shortened lifespan. Problems such as friction, wear and heat will gradually accumulate, causing the performance of the equipment to gradually decline, and eventually it may be scrapped prematurely, which not only increases the company's equipment maintenance and replacement costs, but may also affect the company's production capacity and economic benefits;

[0005] When traditional lubrication devices supply oil to mechanical equipment, they will use distributors to supply oil to multiple oil supply points of the mechanical equipment. The use of distributors increases the cost of the equipment. Failure of one point of the distributor will affect the entire lubrication device, requiring the entire machine to be shut down for maintenance.

[0006] Therefore, in order to solve the problem of poor lubrication of mechanical equipment, the applicant proposes the following multi-line centralized lubrication device. Utility Model Content

DETAILED DESCRIPTION

[0033] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0034] The multi-line centralized lubrication device comprises: a container 100, an oil distributor 200, an oil outlet nozzle 300 and a cam assembly 400.

[0035] The container 100 has a storage chamber 101 for accommodating a medium. The medium here refers to lubricating oil. The type and model of the lubricating oil vary according to the different structures of the oil supply points supplied by the multi-line centralized lubrication device, and are not specifically limited here.

[0036] The specific shape and structure of the container 100 can be various. The container 100 mainly serves to contain the medium, such as Figure 1As shown, the container 100 is generally can-shaped as a whole, and a container cover 110 is arranged on the top of the container 100. The container cover 110 is provided with an oil filling pipe 120, and the medium can be added to the storage chamber 101 through the oil filling pipe 120.

[0037] The bottom of the container 100 is provided with an oil outlet 102 , and the bottom of the container 100 is provided with a structure similar to a convex sleeve / convex ring, and the convex sleeve / convex ring is used for assembly with the oil separator 200 .

[0038] The oil separator 200 is installed at the bottom of the container 100, and an oil storage chamber 201 is formed inside the oil separator 200, and the oil storage chamber 201 is connected to the storage cavity 101;

[0039] The oil separator 200 is arranged in an annular shape, and a plurality of mounting holes are distributed around the outer wall of the oil separator 200. Each mounting hole is equipped with an oil outlet nozzle 300. The axis of the oil outlet nozzle 300 points to the center of the oil separator 200. The oil outlet nozzle 300 can be connected to the oil supply point through a pipeline (hose);

[0040] For example, in automation equipment, most of the movable automation parts need lubricating oil to reduce friction during movement. After long-term use, the lubricating oil in the automation parts may evaporate, and the lubricating oil needs to be replenished in time.

[0041] Then, the multi-line centralized lubrication device of the utility model can be installed in these automated equipment, and each oil nozzle 300 is connected to a movable automated component (ie, oil supply point) through a pipeline (hose) to achieve flexible oil supply.

[0042] Furthermore, each oil outlet nozzle 300 is connected to a plunger, and the opening and closing of the oil outlet nozzle 300 and the oil storage chamber 201 are controlled by the plunger;

[0043] In the initial state, the plunger is kept in a normally closed state and is triggered only by an external force. After the plunger is triggered, the oil outlet nozzle 300 is connected with the oil storage chamber 201, and the lubricating oil is delivered to the oil supply point through the oil outlet nozzle 300.

[0044] The plunger is not shown in the drawings of the specification, but the plunger can adopt a common structure, such as the plunger includes: a main body, a plunger rod and an elastic member, the main body has a first interface and a second interface, the first interface is connected to the oil outlet nozzle, the elastic member and the plunger rod are installed in the main body, and the plunger rod blocks the second interface under the action of the elastic member;

[0045] The travel trajectory of the plunger rod can be parallel to the axis of the oil outlet nozzle it matches, that is, pointing to the center of the oil distributor 200; when the plunger rod is triggered to move, the second interface opens, the lubricating oil enters the inside of the main body through the second interface, then enters the oil outlet nozzle 300 through the first interface, and is finally sent to the oil supply point.

[0046] Furthermore, the cam assembly 400 has a motor bracket 410, a main shaft 420, a motor (not shown in the figure) and a cam (not shown in the figure). The motor drives the cam to rotate in the oil storage chamber 201, and the cam triggers the plunger to connect the oil outlet nozzle 300 with the oil storage chamber 201.

[0047] The motor bracket 410 is assembled in the storage chamber 101, and the motor is assembled in the motor bracket 410; Figure 3 As shown, the motor bracket 410 is barrel-shaped, but its diameter is smaller than the inner diameter of the container 100 , and the main shaft 420 is connected between the power shaft and the cam of the motor, and the main shaft 420 extends from the storage cavity 101 into the oil storage chamber 201 .

[0048] The cam is provided with a triggering portion protruding radially. During the rotation of the cam, different plungers are triggered by the triggering portion, so that different oil outlet nozzles 300 are connected to the oil storage chamber 201 .

[0049] like Figure 1 and Figure 3 As shown, the cam is installed in the oil storage chamber 201. Assuming that the cam rotates one circle in the oil storage chamber 201, the cam triggers each plunger in turn during the rotation, so that each oil outlet nozzle 300 opens in turn to supply oil to the oil supply point.

[0050] According to the needs of the user, the number of the oil outlet nozzles 300 and the size of the triggering portion on the cam can be set, and then the number of plungers triggered by the cam when it is in one position can be adjusted, that is, the number of oil outlet nozzles 300 opened can be controlled;

[0051] like, Figure 1 The density of the oil outlet nozzles 300 is moderate, and each time the triggering part of the cam rotates to a position, a plunger can be triggered, so that one oil outlet nozzle 300 of the multi-line centralized lubrication device is connected to supply oil each time;

[0052] For another example, assuming that a large number of oil nozzles 300 are provided and the distribution is relatively dense, and assuming that the area of ​​the triggering portion of the cam is large enough, when the cam rotates to a position, the triggering portion of the cam can trigger two plungers at the same time, and then the multi-line centralized lubrication device has two oil nozzles 300 connected to supply oil each time;

[0053] Furthermore, if Figure 2 As shown, the oil distributor 200 is provided with one circle of oil nozzles 300, while in other distribution forms, two circles of oil nozzles 300 may be provided. Then, each time the triggering portion of the cam rotates to a position, two plungers may be triggered, and the two corresponding oil nozzles 300 in the multi-line centralized lubrication device are connected at the same time for oil supply.

[0054] Furthermore, it also includes: an agitator 500, the agitator 500 is connected to the power shaft of the motor, and the motor drives the agitator 500 to rotate in the storage chamber 101; or the agitator 500 is connected to the main shaft 420, and the motor drives the agitator 500 to rotate in the storage chamber 101 through the main shaft 420.

[0055] like Figure 3 As shown, the stirring member 500 has a group of stirring arms symmetrically distributed around the main shaft 420 , and the stirring arms are roughly L-shaped and rotate in the storage cavity 101 to stir.

[0056] Furthermore, the oil distributor base 210 is provided with an oil replenishing nozzle 220; when the user uses the multi-line centralized lubrication device, the user can choose to replenish the lubricating oil through the oil filling pipe 120 or replenish the lubricating oil from the oil replenishing nozzle 220 according to the type of lubricating oil required.

[0057] The oil replenishing nozzle 220 is provided with a sealing plug, and the oil replenishing nozzle 220 is closed by the sealing plug when no replenishment is performed.

[0058] For example Figure 2 As shown, it also includes a mounting bracket 600, and the entire multi-line centralized lubrication device is installed on the automation equipment through the mounting bracket 600.

[0059] The multi-line centralized lubrication device of the utility model can control the oil output of each oil nozzle 300 by controlling the rotation speed of the cam and the residence time of the trigger part of the cam at a certain position, so as to achieve the purpose of precise control and distribution. A plurality of oil nozzles are arranged on the oil distributor, each of which is connected to a plunger, and the oil nozzles can be connected to the oil supply point where oil supply is required through a pipeline (hose) to realize "point-to-point" lubrication. Each oil supply point has an independent pipeline for the supply of lubricating oil. Even if a certain oil nozzle or pipeline (hose) is blocked, it will not affect the normal oil supply of other pipelines and will not cause the paralysis of the entire oil supply system.
