Description

Technical Field

[0001] This utility model relates to the field of mechanical lubrication equipment, and in particular to a convenient grease dispenser. Background Technology

[0002] In the maintenance of mechanical equipment, grease dispensers are commonly used to add lubricating grease. Current grease dispensers typically only have one grease reservoir. When the grease in the reservoir is almost depleted, the machine must be stopped, the sealing cap opened, grease added, and then the reservoir resealed. This entire process is not only cumbersome but also interrupts lubrication operations, severely impacting work efficiency.

[0003] According to the utility model patent with announcement number CN222797804U, a dual-coil two-position four-way electromagnetic reversing valve is disclosed. It achieves oil circuit switching by driving the valve core to move through the electromagnetic coil. However, it has the disadvantages of complex structure and electric drive, and insufficient reliability under no-electricity or harsh working conditions.

[0004] According to the utility model patent with announcement number CN223063640U, an embedded bearing oil receiving device is disclosed. It accurately captures and guides the overflowing grease away from key components through an embedded arc-shaped receiving plate, uses a preset tilt angle for diversion, and achieves convenient installation with the help of the original screws of the equipment through a fixing plate. This demonstrates a collection and diversion scheme for grease overflow on a specific device. However, the device passively receives the overflowing grease, rather than being used for an active, continuous grease supply system.

[0005] The aforementioned existing technologies mostly focus on preventing lubricant leakage and collection, or employ complex control methods. Therefore, there is a lack of a grease machine in the existing technology that can ensure continuous and uninterrupted operation during grease filling, thereby significantly improving work efficiency. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, the present invention solves the technical problem by integrating the dual grease chamber and the mechanical three-way reversing valve into a simple, reliable, and low-cost purely mechanical method, which perfectly solves the drawback of having to stop the grease machine when adding grease, and realizes the convenience of the operation process. It is especially suitable for modern production lines and equipment maintenance occasions that require continuous operation.

[0007] The convenient grease dispenser provided by this utility model includes: a main frame, a pumping mechanism on the main frame, an oil gun connected to the outlet of the pumping mechanism via a hose, and a dual-compartment alternating grease supply mechanism on one side of the pumping mechanism for conveying grease.

[0008] The dual-compartment alternating grease supply mechanism includes a first grease compartment, a second grease compartment, and a three-way reversing valve. The bottom of both the first and second grease compartments has an outlet. The outlets of the first and second grease compartments are respectively connected to both ends of the three-way reversing valve. The other end of the three-way reversing valve is connected to the feed inlet of the pumping mechanism.

[0009] Preferably, the three-way reversing valve is a plug valve, and a drive handle is provided on one side of the plug valve, the drive handle being connected to the valve core inside the plug valve.

[0010] Preferably, the pumping mechanism is a plunger pump, and a motor is provided on one side of the plunger pump. The output end of the motor is connected to the valve stem of the plunger pump through a coupling.

[0011] Preferably, the bottom ends of the first and second grease tanks are both conical, and the diameter of the bottom outlet of the cone is smaller than the diameter of the top surface.

[0012] Preferably, both the first and second grease tanks are connected to the main frame via a support frame, and one of the support frames has an oil gun placement chamber connected to its outer wall, where the oil gun is placed.

[0013] Preferably, the oil gun placement chamber has a slot that matches the oil gun, the inner wall of the slot is provided with a magnetic sticker, and the outer surface of the oil gun is provided with a corresponding magnetic sticker.

[0014] Preferably, the bottom of the main frame is provided with casters.

[0015] Preferably, the outer walls of the first and second grease tanks are covered with an insulation layer.

[0016] Compared with related technologies, the convenient grease filling machine provided by this utility model has the following beneficial effects: Through the design of alternating operation of dual grease tanks, when the working grease tank is about to run out, the operator only needs to pull the handle once, and the machine can be switched to the spare grease tank in just a few seconds without stopping the machine. This fundamentally eliminates the downtime caused by filling, resulting in a qualitative leap in equipment utilization and overall efficiency of lubrication operations, and achieving true non-stop filling.

[0017] By allowing one grease tank to be filled while the other is working, the continuity and efficiency of lubrication operations are ensured. This avoids the drawback of traditional equipment, which requires a cumbersome process of "stopping the machine, opening the cover, filling the grease, sealing, and restarting" when the grease is exhausted, thus preventing the lubrication operation from being interrupted.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figures 1 to 5 The present invention provides a convenient grease dispenser, including a main frame 1, with multiple casters connected to the bottom of the main frame 1 and a trolley handle connected to the main frame 1, thereby pushing the entire device to move.

[0026] The main frame 1 is equipped with a pumping mechanism 2. The outlet of the pumping mechanism 2 is connected to an oil injection gun 3 through a hose. The pumping mechanism 2 can pump out the grease in the first grease tank 41 and the second grease tank 42 through the oil injection gun 3.

[0027] It should be noted that, since a slot 451 matching the oil gun 3 is provided in the oil gun placement chamber 45, the oil gun 3 can be placed in the oil gun placement chamber 45. In order to avoid the oil gun 3 falling out, magnetic stickers are installed on the inner wall of the slot 451 and on the outer surface of the oil gun 3. The positions of the two magnetic stickers are set accordingly. In this way, after the oil gun 3 is placed in the slot 451, the magnetic force of the two magnetic stickers can firmly attract the oil gun 3 into the slot 451, thereby avoiding the disadvantage of the oil gun 3 falling out.

[0028] Please see Figure 1 The first grease tank 41 and the second grease tank 42 are fixedly installed side by side on the main frame 1 via the support frame 44. The top of the first grease tank 41 and the second grease tank 42 are provided with tank covers, which are connected to the tank body by hinges to facilitate opening and adding grease. The contact surface between the tank cover and the opening of the tank body can be fitted with sealing strips to enhance the sealing effect and prevent impurities from entering.

[0029] It is worth noting that during the operation of the first grease tank 41, the operator can open the cover of the second grease tank 42 and add new grease. After adding grease, the cover is closed and locked, and the first grease tank 41 becomes a backup tank. It can be switched back to the second grease tank 42 when it is depleted. This cycle allows for truly uninterrupted operation.

[0030] Both the first grease tank 41 and the second grease tank 42 have outlets at their bottoms. The bottom ends of both the first grease tank 41 and the second grease tank 42 are conical, and the diameter of the outlet at the bottom of the cone is smaller than the diameter at the top. This helps the grease to gather at the outlet under the action of gravity, reducing grease residue.

[0031] It should be noted that a dual-compartment alternating grease supply mechanism 4 is provided on one side of the pumping mechanism 2. The dual-compartment alternating grease supply mechanism 4 delivers grease, and the design of alternating operation of the two grease compartments achieves the effect of non-stop lubrication. When one grease compartment is working, the other grease compartment can be filled, ensuring the continuity and high efficiency of lubrication operations. This avoids the inconvenience of replenishing new grease when the grease is about to run out, which requires stopping the machine and affects work efficiency.

[0032] Please see Figure 1 and Figure 2 The dual-compartment alternating grease supply mechanism 4 includes a first grease compartment 41, a second grease compartment 42, and a three-way reversing valve 43. The three-way reversing valve 43 is fixed on the main frame 1 by a bracket and is located at the junction of the outlets of the first grease compartment 41 and the second grease compartment 42. The three-way reversing valve 43 is a plug valve. A drive handle 431 is provided on one side of the plug valve. The valve core of the plug valve is machined with a specific flow channel. By rotating the valve core through the external drive handle 431, the connection relationship of the flow channel can be changed.

[0033] It should be noted that the outlets of the first grease tank 41 and the second grease tank 42 are both connected to the inlet of the three-way directional valve 43, and the outlet of the mechanical three-way directional valve 43 is connected to the inlet of the pumping mechanism 2; the valve core of the mechanical three-way directional valve 43 has a first working position (e.g., Figure 3 ) and second work position (e.g. Figure 4 When the valve core is in the first working position, the outlet of the first grease chamber 41 is connected to the inlet of the pumping mechanism 2, and the outlet of the second grease chamber 42 is blocked; when the valve core is in the second working position, the outlet of the second grease chamber 42 is connected to the inlet of the pumping mechanism 2, and the outlet of the first grease chamber 41 is blocked.

[0034] Please see Figure 1 and Figure 2 The pumping mechanism 2 uses a reciprocating plunger pump 21, which is driven by a motor 22 mounted on the main frame 1. The inlet of the plunger pump 21 is connected to the outlet of the three-way reversing valve 43 through a pipeline, and its outlet is connected to the output hose and the oil gun 3.

[0035] The plunger pump 21 is equipped with a grease inlet check valve at its inlet and a grease outlet check valve at its outlet.

[0036] Please see Figure 1 and Figure 3 It is worth noting that in the initial state, the drive handle 431 is positioned in a horizontal position biased to one side (e.g., Figure 3 At this point, the valve core flow channel connects the outlet of the first grease chamber 41 to the inlet of the pumping mechanism 2, while simultaneously blocking the outlet of the second grease chamber 42. After the pumping mechanism 2 is started, the plunger begins to reciprocate under the drive of the motor 22. During the grease suction stroke, the plunger moves backward, creating a negative pressure in the pump chamber. The grease inlet check valve opens under the pressure difference, allowing the grease in the first grease chamber 41 to enter the pump chamber. Simultaneously, the grease outlet check valve remains closed under the residual pressure of the system and the spring force.

[0037] During the grease compression stroke, the plunger moves forward, applying pressure to the grease in the pump chamber. When the pressure exceeds the system resistance, the grease outlet check valve opens, and the grease is delivered to the grease gun 3 via the outlet hose. At this time, the grease inlet check valve closes tightly under pressure to prevent grease backflow.

[0038] The operator can observe the grease level change in the first grease tank 41 through the transparent window 46; when it is observed through the transparent window 46 that the grease level in the first grease tank 41 is about to reach the bottom, the operator does not need to stop the machine, but only needs to rotate the drive handle 431 from the horizontal position to the vertical position of 90 degrees (e.g., Figure 4 This operation is completed instantly, and the lubrication process continues uninterrupted. At this time, the valve core flow channel changes, connecting the outlet of the second grease tank 42 with the inlet of the pumping mechanism 2, while simultaneously blocking the outlet of the first grease tank 41. The pumping mechanism 2 immediately begins to draw grease from the second grease tank 42, achieving seamless and continuous lubrication.

[0039] It is worth noting that this equipment uses only one pumping mechanism 2 and one reversing valve. The rotation of the valve core fundamentally ensures the uniqueness and sealing of the grease flow path, avoiding the cumbersome operations and potential leaks associated with traditional methods that require valve closure, disassembly, and connection. Furthermore, because all components are integrated onto a single main frame 1 and share a single moving system, the overall design is highly integrated, occupies a small area, and exhibits good synchronous movement. During operation, the operator only needs to operate the reversing valve handle once to switch the grease supply source. This process can be completed within seconds, truly achieving "non-stop operation."

[0040] It is worth mentioning that, compared to this equipment, using two oil receiving vehicles would require: walking to the other equipment → picking up another oil injection gun 3 → possibly closing a valve on the other equipment → starting work. This process is more time-consuming, cumbersome, and requires operators to move around. It also requires two pumping systems, two moving mechanisms, and two oil injection guns 3, increasing manufacturing costs.

[0041] It should be noted that the outer walls of the first grease tank 41 and the second grease tank 42 are wrapped with a 10mm thick layer of polyethylene insulation cotton as an insulation layer, and are wrapped and fixed with aluminum foil to prevent the grease from hardening when the equipment is working in a low-temperature environment and to ensure its fluidity.

[0042] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes that element.

However, as previously stated, it should be understood that this application is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the conception outlined herein through the foregoing teachings or techniques or knowledge in related fields.
