[0002] With the acceleration of industrialization, casters are widely used in all walks of life and have become an indispensable component of many equipment. Casters achieve rolling and sliding through the bearings inside them. During the production process of casters, butter needs to be injected into the bearings to provide lubrication for the casters during operation, thereby reducing heat generation and avoiding bearing damage. On the existing production line, a pumping pipe is required to pump the butter in the butter barrel to the bearing injector. However, since butter is not in the form of water and has a certain viscosity, the pumping pipe often inhales air during pumping and cannot completely absorb the butter in the butter barrel, resulting in some bearings failing to be continuously filled with butter and a large amount of butter remaining in the butter barrel.

DETAILED DESCRIPTION
[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0023] like Figure 1-4 As shown, a grease pumping device comprises a bottom plate 1, a top plate 2, a lifting structure, a hydraulic cylinder 7, a piston cover 8 and a delivery pipe 10. A guide column 3 is provided on the bottom plate 1, and a guide sleeve 4 is provided on the top plate 2. The guide column 3 is slidably connected with the guide sleeve 4 to provide a guide for the lifting and lowering of the top plate 2. The bottom plate 1 and the top plate 2 are connected through the lifting structure. The hydraulic cylinder 7 is fixed on the top plate 2. The piston cover 8 is movably connected to the lower end of the hydraulic cylinder 7. Driven by the lifting structure, the hydraulic cylinder 7 and the piston cover 8 can move up and down, so as to install the piston cover 8 into or remove it from the grease barrel 19. A delivery pump 9 is provided on the piston cover 8. The delivery pipe 10 is connected to the lower end of the piston cover 8 through the delivery pump 9. When the hydraulic cylinder 7 pushes the piston cover 8 to move up and down, the grease is compressed and flows into the delivery pipe 10. With the help of the delivery pump 9, the grease is pumped to the inside of the caster.
[0024] In the above embodiment, the lifting structure includes a climbing rack 6 and a climbing motor. The climbing rack 6 is fixed on the bottom plate 1, and the climbing motor is fixed on the top plate 2. The top plate 2 is provided with a notch. The climbing rack 6 passes through the notch and is connected to the motor for transmission. When the climbing motor rotates, the output end of the climbing motor meshes with the climbing rack 6 through a gear. The top plate 2 connected to the climbing motor moves up and down under the joint action of the climbing motor, the climbing rack, the guide column 3, and the guide sleeve 4, driving the piston cover 8 to be inserted into or removed from the butter barrel 19. The top plate 2 is provided with a guide hole 12, and the delivery pipe 10 is slidably connected to the guide hole 12, which can prevent the delivery pipe 10 from shaking or tilting during the pumping process, thereby causing damage to the connection between the delivery pipe 10 and the delivery pump 9, and can also vertically pump out the butter to reduce the pumping resistance. The piston cover 8 is provided with a rubber ring 11, which surrounds the side of the piston cover 8 for a week to seal and prevent the butter from overflowing from the butter barrel 19 and the piston cover 8.
[0025] In the above embodiment, the bottom plate 1 is provided with a mounting groove 14, which fits the shape of the butter barrel 19, and can not only provide positioning for the butter barrel 19, but also make the butter barrel 19 be placed firmly. The side of the mounting groove 14 is provided with an opening, and the butter barrel 19 can be pushed, loaded and unloaded from the side of the mounting groove 14, which is convenient for workers to operate. The bottom plate 1 is provided with a positioning groove 16, which is located on both sides of the mounting groove 14. The positioning groove 16 is embedded with a fixing plate 13 to further fix the butter barrel 19 to prevent the butter barrel 19 from deviating from the position and to prevent the piston cover 8 from being misaligned with the middle of the butter barrel 19. The fixing plate 13 can be fixed by means of screws or the like. Positioning keys 15 are provided at both ends of the fixing plate 13, and the fixing plate 13 is embedded in the positioning groove 16 through the positioning keys 15 to lock the fixing plate 13 to prevent it from slipping out laterally; the fixing plate 13 is provided with an arc-shaped notch 17 on the side facing the mounting groove 14, which adapts to the shape of the butter barrel 19 and makes the butter barrel 19 more firmly placed. The bottom plate 1 and the fixing plate 13 are provided with a wire 18, and the wire 18 forms a loop at the positioning key 15 and the positioning groove 16. The lifting motor is in the loop. When the loop is connected, the lifting motor can be started to ensure that the piston cover 8 is aligned with the middle of the butter barrel 19, so as to avoid the piston cover 8 hitting the upper end of the butter barrel 19 and failing to work normally. The piston cover 8 is provided with a valve 20, which plays a role in balancing the air pressure when the piston cover 8 is separated from the butter barrel 19.
[0026] Description of the working method of this utility model:
[0027] The butter barrel 19 loaded in the present device is uniformly customized, and its outer diameter is adapted to the mounting groove 14 and the arc-shaped notch 17, and its inner diameter is adapted to the outer diameter of the piston cover 8; the unopened butter barrel 19 is pushed into the mounting groove 14 from the side, and the positioning keys 15 at both ends of the fixing plate 13 are embedded in the positioning grooves 16, so that the arc-shaped notch 17 of the fixing plate 13 is against the side of the butter barrel 19. At the same time, the wires 18 inside the bottom plate 1 and the fixing plate 13 form a loop, and the climbing motor in the loop is energized and in standby mode; the upper cover of the unopened butter barrel 19 is lifted off, and the top plate 2 is controlled to descend by the climbing motor, thereby driving the hydraulic cylinder 7 and the piston cover 8 to descend, so that the piston cover 8 is just embedded in the butter barrel 19. Under the lubrication of butter, the friction between the piston cover 8 and the inner wall of the butter barrel 19 is small, and the piston cover 8 slides up and down smoothly in the butter barrel 19. Under the sealing effect of the rubber ring 11, butter is difficult to overflow from between the piston cover 8 and the inner wall of the butter barrel 19. When the piston cover 8 is completely embedded in the butter barrel 19, the climbing motor is controlled to stop rotating. At this time, the hydraulic cylinder 7 and the delivery pump 9 can be started to push the piston cover 8 at the lower end of the hydraulic cylinder 7 to continue to extend into the butter barrel 19, and the delivery pump 9 starts to extract butter; during the downward movement of the piston cover 8, the piston cover 8 cooperates with the delivery pump 9 to first exhaust the air in the butter barrel 19, and then fill the delivery pipe 10 with butter; when the butter is pushed out of the delivery pipe 10, the delivery pump 9 can be adjusted or stopped, and the oil injection operation can be performed according to production requirements. When the butter in the butter barrel 19 is exhausted, the valve 20 is opened to balance the air pressure inside and outside the butter barrel 19, so that the piston cover 8 can rise smoothly under the contraction of the hydraulic cylinder 7. When the piston cover 8 is out of the butter barrel 19, the fixing plate 13 can be removed, and the butter barrel 19 can be removed from the side of the mounting groove 14. Compared with the prior art, the present device greatly improves the utilization rate of the butter in the butter barrel 19, and avoids the situation where a large amount of air is filled in the delivery pipe 10 during the caster oiling process as much as possible, thereby ensuring the caster oiling quality.
