The oil supply member is used to transport the lubricating oil in the oil tank 3 to the oil brushing member. The driving member acts on the oil supply member and is used to drive it to operate intermittently.

[0029] When the lubrication process of the conveyor chain is completed, the movable seat 5 is driven to slide to the initial position, and the conveyor chain is removed from the sprocket 7.

[0030] To sum up, when the present application is in use, the driving member drives the oil supply member to operate intermittently, and the oil supply member intermittently transports the lubricating oil in the oil tank 3 to the oil brush member, and the lubricating oil is brushed onto multiple conveying chains through the oil brush member to achieve lubrication of the conveying chains. This can avoid excessive oil output, thereby avoiding excessive lubricating oil adhering to the conveying chain, reducing the waste of lubricating oil, and is therefore more practical.

[0031] like Figure 4-Figure 6 As shown, in some embodiments, the oil brushing member includes a first oil storage box 8 arranged on the cross bar 4, the first oil storage box 8 is fixed on the cross bar 4, the oil supply member is used to transport the lubricating oil in the oil tank 3 to the first oil storage box 8, and the cross bar 4 is rotatably provided with brush rollers 9 of the same number and one-to-one correspondence as the conveying chain, the brush rollers 9 are in a horizontal direction and roll-over with the conveying chain, and a plurality of brush rollers 9 are distributed in an array along the horizontal direction, and the first oil storage box 8 is provided with first cotton strips 10 of the same number and one-to-one correspondence as the brush rollers 9, the first cotton strips 10 are in a vertical direction and fixed on the first oil storage box 8, the top end of the first cotton strips 10 extends to the inner bottom surface of the first oil storage box 8, and the bottom end corresponds to the brush roller 9;

When the conveying chain moves, the brush roller 9 rotates and brushes the lubricating oil onto the conveying chain.

When in use, the piston rod 15 is driven by the driving member to slide back and forth in a straight line. The piston rod 15 first slides to the extreme position and unblocks the oil inlet pipe 12 and the delivery pipe 13. During this process, the fixed cylinder 11 tends to be in a negative pressure state, and the lubricating oil in the oil tank 3 enters the fixed cylinder 11 through the oil inlet pipe 12. Then the piston rod 15 slides to the initial position. During this process, the lubricating oil in the fixed cylinder 11 enters the delivery pipe 13, the hose and the first oil storage box 8 in turn, and this is repeated to achieve intermittent delivery of the lubricating oil in the oil tank 3 to the first oil storage box 8.

The lubricating oil in the conveying pipe 13 is passed through the hose into the oil brushing part, and the lubricating oil is brushed onto multiple conveying chains through the oil brushing part. Conversely, when the lubrication treatment of the conveying chain is completed, the forward and reverse screw rods 21 are driven to reverse, and the moving rod 20 and the cross bar 4 are synchronously slid in the opposite directions due to the action of the forward and reverse threads to be far away from each other, so as to facilitate the subsequent removal of the conveying chain.
