Description

Technical Field

[0001] This utility model relates to a valve body, specifically to a grease machine. Background Technology

[0002] When mechanical equipment or motor vehicles have many frequently operating and high-speed components, after a certain period of operation, these moving parts generally need to be lubricated with grease or other oils to prevent high temperatures and wear caused by friction between the moving parts. However, existing grease machines are generally operated manually or by foot, such as lever-type manual grease machines. These methods are inconvenient in several ways: First, filling the grease machine requires manual filling of the reservoir and then closing the lid, which is time-consuming, laborious, and can easily cause personal contamination. Second, when adding grease to moving parts, one hand must hold the grease machine while the other hand continuously presses the lever up and down. Especially when used in motor vehicles, sometimes a person has to lie under the vehicle to slowly add grease to the moving parts. These grease machines are cumbersome to operate, waste a lot of grease, cause high labor intensity for workers, and have low work efficiency.

[0003] A grease dispenser, also known as a grease injector or grease filling machine, is a pressure-increasing machine used to inject grease into a lubrication station. Existing grease dispensers include pneumatic or electric drives, and are equipped with a pump head consisting of a pressure gauge and various connectors, a grease gun connected to the connectors, a pump body extending into the grease container, a container cap that is penetrated by the pump body and fixed to the opening of the grease container, and a pressure plate fitted onto the pump body to press against the grease inside the container.

[0004] When using it, the grease needs to be scooped out of the packaging container and then poured into the grease container. After that, the pump head power source pressurizes the grease sealed by the pressure plate through the pump body, and then it can be discharged through the grease gun.

[0005] When operating a current grease machine, it is difficult to add new grease to the grease container, and the pump body cannot be easily and quickly removed as a whole. Grease containers are often wider at the top and narrower at the bottom, and the pressure plates on the market cannot scrape the grease off the container walls cleanly. If the pressure plate is too small, it will cause false overflow at the top of the container, and if the pressure plate is too large, it will get stuck halfway through the process, requiring the pressure plate to be replaced (this is the current situation with electric grease machines).

Detailed Implementation

[0035] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0036] Depend on Figure 1 Combination Figure 2-5 As shown, a grease dispenser includes an inlet 1, an outlet 2, and a container 3. The container 3 has a receiving cavity 31 for holding grease. It also includes:

[0037] A control pump 4 is located inside the accommodating cavity 31. The control pump 4 is equipped with a control piston 41, which is used to draw the grease in the accommodating cavity 31 into the control pump 4 and deliver it to the oil outlet 2. The oil inlet 1 is located on the control pump 4 and is used to communicate with the accommodating cavity 31.

[0038] Power unit 5, which includes a drive component 51 and a transmission shaft 52;

[0039] The eccentric device 6 is connected to the drive component 51 via a transmission shaft 52, which in turn drives the eccentric device 6 to move. The eccentric device 6 is connected to the control piston 41, which in turn drives the control piston 41 to reciprocate within the control pump 4. The advantages of this invention are that the drive component reliably drives the eccentric device, thereby driving the control piston to move, achieving reliable oil injection. The product has a simple structure, few potential failure points, and is easy to operate, greatly improving maintenance speed and minimizing grease waste. This allows the power unit and control pump to be removed as a whole, facilitating reliable grease addition and simplifying operation. Specifically, the drive component 51 is connected to the eccentric device 6 via the transmission shaft 52 and is used to drive the eccentric device 6 to move; that is, the transmission shaft drives the eccentric shaft 61 to rotate; since the control pump 4 is provided with a guide groove 42, the transmission plate 62 is located in the guide groove 42 and slides horizontally with the control pump 4; that is, the transmission plate is located in the control pump and is limited by the space in the control pump. A slot is provided on the transmission plate. At this time, the circumferential rotation of the eccentric shaft is converted into the horizontal movement of the transmission plate. The control piston 41 is located on the transmission plate and is driven by the transmission plate to reciprocate. Since the oil inlet 1 is located on the control pump 4 and is used to connect with the accommodating cavity 31, a one-way valve is usually provided at the oil inlet to prevent oil backflow; in this utility model, there are two control pistons. For ease of description, the left piston is described as the first piston and the right piston as the second piston. The pistons are located in the control pump to form a rodless chamber and a rod chamber. When the transmission plate moves to the right, the first piston opens the one-way valve through negative pressure and draws the grease or lubricating oil in the container 3 into the control pump chamber (similar to drawing the grease or lubricating oil into the rodless chamber through vacuum). At this time, the first piston is in the oil suction stage, and the second piston is in the oil injection stage. When the transmission plate moves to the left, the one-way valve closes, and the first piston pushes the grease in the rodless chamber out through the first channel. The first channel 43 is connected to the oil outlet through the second channel 551. At this time, the discharged grease is used for oil injection, and the second piston is in the oil suction state. In fact, the action of the second piston is the same as or similar to that of the first piston. In reality, only one piston is set up to achieve oil suction and oil injection by moving the piston to the left and right.

[0040] The eccentric device 6 includes an eccentric shaft 61 and a transmission plate 62. The eccentric shaft 61 is mounted on and linked to the transmission shaft 52. The transmission plate 62 is driven by the eccentric shaft 61 and is used to drive the control piston 41 to reciprocate. In this way, the rotation of the eccentric shaft can reliably drive the transmission plate to reciprocate, thereby making the control piston move reliably and achieving reliable oil injection.

[0041] There are two control pistons 41, and the two control pistons 41 are symmetrically arranged. This structure makes the product easy, fast, efficient, and smooth to fill with oil. A one-way valve is usually provided at the oil inlet to prevent oil backflow.

[0042] The transmission plate 62 is provided with a transmission groove 621, and the eccentric shaft 61 is inserted into the transmission groove 621 to drive the transmission plate 62 to reciprocate horizontally. Specifically, the control pump 4 is provided with a guide groove 42, and the transmission plate 62 is disposed in the guide groove 42 and slides horizontally with the control pump 4. This structure makes the product operation smooth and reliable.

[0043] This utility model also includes:

[0044] A pressure cap 53 is sleeved on the outside of the drive shaft 52, and the pressure cap 53 is located above the oil inlet 1;

[0045] The pre-compression elastic element 54 is sleeved outside the drive shaft 52 and abuts against the pressure cap 53 to press the pressure cap 53. The pressure cap and the pre-compression elastic element are designed to facilitate pressing the grease and ensure reliable discharge.

[0046] The barrel body 3 has a frustum-shaped structure, wider at the top and narrower at the bottom. The pressure cap 53 is provided with a pressing part 531 and a scraping part 532. The scraping part 532 is flexibly and swingably arranged relative to the pressing part 531. This facilitates reliable addition of butter.

[0047] This utility model also includes a sleeve 55. The control pump 4 is provided with a first channel 43. The sleeve 55 is sleeved outside the drive shaft 52 and forms a second channel 551 between it and the outer wall of the drive shaft 52. The oil inlet 1 is connected to the oil outlet 2 through the first channel 43 and the second channel 551. This structure makes reasonable use of the drive shaft and facilitates reliable material feeding.

[0048] This invention also includes a planetary transmission assembly 56, through which the drive component 51 is connected to the transmission shaft 52 and drives the transmission shaft 52 to rotate. This structure ensures reliable product transmission, a simple structure, high torque, and facilitates reliable material feeding.

[0049] This utility model also includes:

[0050] Top cover 71, the cover is placed on the barrel body 3;

[0051] Handle 72 is provided on the barrel body 3 for easy handling;

[0052] A cover 73 is located at the drive unit 51. The cover 73 has a first position where it is positioned outside the drive unit 51 during installation and a second position where it is swung open. This structure facilitates the movement of the grease machine, is simple in design, and the cover shields the power unit, resulting in a long product lifespan.
