Description

Technical Field

[0001] This application relates to the field of lubrication equipment technology, and in particular to a grease machine. Background Technology

[0002] Traditional grease presses suffer from the inconvenience of storing the grease hose during use. To address this, existing technologies employ a separate storage mechanism for winding and storing the hose. However, this solution has significant drawbacks: firstly, the connection between the grease hose and the reservoir is complex, increasing the difficulty of assembly and maintenance; secondly, while the winding mechanism rotates, the reservoir remains stationary, resulting in poor overall equipment coordination and cumbersome operation due to this separate design. These technical shortcomings severely impact the efficiency and ease of use of the grease press. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this application provides a grease machine that has the advantages of simplifying the grease hose storage structure and improving the coordination of equipment operation.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] A grease press includes a frame, a grease reservoir rotatably mounted on the frame, and a grease hose with one end connected to the bottom of the grease reservoir. The outer wall of the grease reservoir is provided with a connector, and the grease hose is at least partially wound around the outside of the connector.

[0006] Through the above technical solution, this application achieves convenient storage of grease hoses. The rotatable design of the oil reservoir allows the hose to naturally wind or unwind, avoiding the connection complexity of an independent storage mechanism. The connector provides a stable winding support surface for the hose, preventing it from slipping or becoming disorderly when stacked on the oil reservoir surface. This integrated design simplifies the overall structure, reduces the risk of mechanical interference, and improves the stability and reliability of the equipment. Simultaneously, the direct connection between the hose and the oil reservoir eliminates cyclic torsional stress, extends the service life of the sealing structure and the hose, and reduces maintenance frequency and operating costs.

[0007] Furthermore, this application also proposes that the connector is a cylindrical structure, the connector is fitted onto the outside of the oil storage tank and fixed circumferentially to the oil storage tank, and the outer wall of the connector is provided with a spiral guide groove, and the grease hose is wound around the outside of the connector along the guide groove.

[0008] Through the above technical solution, this application achieves a stable connection between the connector and the oil storage tank. The design of the spiral guide groove provides a clear winding path for the grease hose, effectively guiding the hose to wind along a predetermined trajectory and preventing the hose from shifting or loosening during the winding process.

[0009] Furthermore, this application also proposes that the frame is provided with a transmission assembly and a guide, the guide being slidably connected to the frame in a vertical direction, and the transmission assembly drivingly connecting the oil storage tank and the guide so that the guide is synchronously raised and lowered when the oil storage tank rotates.

[0010] Through the above technical solution, this application achieves active guidance in the grease hose winding process. The synchronous lifting and lowering movement of the guide effectively controls the winding trajectory of the grease hose, avoiding problems such as loosening, uneven winding, or deviation of the hose during the winding process.

[0011] Furthermore, this application also proposes that when the oil storage tank rotates one revolution in the forward direction, the transmission assembly drives the guide to rise one pitch in the guide groove, and when the oil storage tank rotates one revolution in the reverse direction, the transmission assembly drives the guide to fall one pitch in the guide groove.

[0012] Through the above technical solution, this application achieves precise synchronization between the rotation of the oil storage tank and the movement of the guide component. For each rotation of the oil storage tank, the guide component moves by one pitch height, ensuring that the grease hose is evenly distributed along the spiral path of the guide groove during winding. This solution avoids the problem of misalignment or loosening of the grease hose during winding, improving the grease hose storage effect and the stability of the equipment.

[0013] Furthermore, this application also proposes that the transmission assembly includes a first pulley, a second pulley, a transmission belt, a lead screw, and a nut. The first pulley is coaxially fixed to the oil storage tank, the second pulley is coaxially fixed to the lead screw, the transmission belt drives and connects the first pulley and the second pulley, the lead screw is rotatably connected to the frame, the nut is sleeved on the outside of the lead screw and threadedly connected to the lead screw, and the guide is fixed to the nut.

[0014] Through the above technical solution, this application achieves precise conversion between the rotational motion of the oil storage tank and the linear motion of the guide component. The pulley drive mechanism simplifies the power transmission process, and the screw and nut mechanism precisely converts the rotational motion into linear motion, ensuring the synchronization of the guide component's lifting amplitude with the number of rotations of the oil storage tank.

[0015] Furthermore, this application also proposes that the pitch of the guide groove is L1, the pitch of the lead screw is L2, and the transmission ratio of the first pulley and the second pulley is n1:n2, where L2:L1 = n1:n2.

[0016] Through the above technical solution, this application achieves precise synchronization between the rotation of the oil reservoir and the lifting of the guide. Specifically, by setting the proportional relationship between the guide groove pitch, the lead screw pitch, and the pulley transmission ratio, it is ensured that the guide can precisely rise or fall by one screw pitch for each rotation of the oil reservoir, so that the guide is always aligned with the guide groove position where the grease hose is being wound.

[0017] Furthermore, this application also proposes that the frame is provided with a first rotating drive for driving the oil storage tank to rotate.

[0018] Through the above technical solution, the first driving component directly drives the oil storage tank to rotate around its own axis, making the winding process of the grease hose smoother and avoiding the problem of the grease hose coming loose.

[0019] Furthermore, this application also proposes that the first drive component and the oil reservoir are connected by a clutch assembly.

[0020] Through the above technical solution, this application realizes rapid switching control of the power transmission system of the grease machine.

[0021] Furthermore, this application also proposes that the guide is provided with a first clamping wheel, a second clamping wheel and a second driving member, the second driving member drives the first clamping wheel to rotate, and the first clamping wheel and the second clamping wheel clamp the grease hose.

[0022] Through the above technical solution, the second driving component directly drives the first clamping wheel to rotate, converting the rotational motion into linear conveying power for the hose, thereby realizing the active driving of the hose during the elongation process and eliminating the risk of jamming that occurs when the hose is passively pulled by the rotation of the oil storage tank in the traditional solution.

[0023] Furthermore, this application also proposes that the guide is provided with a third driving member, which drives the first clamping wheel or the second clamping wheel to move so that the first clamping wheel and the second clamping wheel move closer or further apart from each other, and clamp or release the grease hose.

[0024] Through the above technical solution, this application achieves rapid switching of the grease hose clamping state. Attached Figure Description

Detailed Implementation

[0028] The present application will now be further described with reference to the accompanying drawings and specific embodiments.

[0029] Example 1:

[0030] like Figure 1 and Figure 2 As shown, a grease maker includes a frame 1, a grease tank 2 rotatably mounted on the frame 1, and a grease hose 3 with one end connected to the bottom of the grease tank 2. A connector 4 is provided on the outer wall of the grease tank 2, and the grease hose 3 is at least partially wound around the outside of the connector 4. A spiral guide groove 4.1 is provided on the outer wall of the connector 4, and the grease hose 3 is wound along the guide groove 4.1 around the outside of the connector 4. The grease tank 2 is vertically positioned, with an opening at the top and a lid that can be closed.

[0031] The frame 1 refers to the frame structure used to support and fix other components. It can be implemented using a welded metal frame or an injection-molded bracket, providing a stable rotational support base for the oil storage tank 2. The oil storage tank 2 is the container used to store grease. It can be implemented using a cylindrical metal or plastic tank, and its rotation mechanism enables the automatic winding function of the grease hose 3. The grease hose 3 is the flexible pipe used to transport grease. It can be implemented using a rubber hose or a polyurethane hose, with one end connected to the bottom of the oil storage tank 2 to ensure the continuity of the grease transport path. The connector 4 is a component fixed to the outside of the oil storage tank 2 to guide the hose winding.

[0032] The core innovation of this application lies in designing the oil reservoir 2 as a rotatable structure and providing a connector 4 with a guiding function on its outer wall, allowing the grease hose 3 to be directly wound around the surface of the connector 4 as the oil reservoir 2 rotates. This design integrates the hose storage function with the oil reservoir 2 itself, completing the hose winding and unwinding operations synchronously during rotation. This eliminates the structural complexity of the connection between the independent storage mechanism and the oil reservoir 2, and achieves orderly hose arrangement through the rotation of the oil reservoir 2, solving the problem of hose storage difficulties caused by the oil reservoir 2 being stationary in traditional solutions. The rotational characteristics of the oil reservoir 2 eliminate the need for additional adjustments to the connection when storing the hose. When the oil reservoir 2 rotates, the grease hose 3 winds or unwinds accordingly. The connector 4 integrates the hose storage function with the oil reservoir 2 itself, simplifying the structure. The connector 4 remains circumferentially fixed to the oil reservoir 2, ensuring that the hose winding trajectory is synchronized with the rotation of the oil reservoir 2.

[0033] To use, pull the free end of the grease hose 3 to the desired length for filling. After filling, rotate the oil reservoir 2, and the hose will form an orderly spiral winding on the outer surface of the connector 4. Since the connector 4 is fixed to the oil reservoir 2, the hose will not slip during winding, ensuring storage stability.

[0034] As a preferred embodiment, the solution of this application is implemented as follows: The connector 4 adopts a cylindrical structure and can be made of metal or engineering plastic material. The connector 4 is fitted onto the outside of the oil reservoir 2 and is circumferentially fixed to the oil reservoir 2 by bolts or clips. The outer wall of the connector 4 is provided with a spiral guide groove 4.1, and the pitch of the guide groove 4.1 can be designed to match the diameter of the grease hose 3. The grease hose 3 is wound around the outside of the connector 4 along the guide groove 4.1, thereby forming an orderly wound structure.

[0035] In another embodiment, the connector 4 and the oil storage tank 2 are integrally formed and can be manufactured by injection molding or metal casting. The outer wall of the connector 4 is also provided with a spiral guide groove 4.1, and the grease hose 3 is wound around the outside of the connector 4 along the guide groove 4.1.

[0036] Preferably, this application further proposes that the frame 1 is provided with a transmission assembly 5 and a guide 6, the guide 6 is slidably connected to the frame 1 in a vertical direction, and the transmission assembly 5 is connected to the oil storage tank 2 and the guide 6 in a transmission manner, so that when the oil storage tank 2 rotates, it drives the guide 6 to rise and fall synchronously.

[0037] Specifically, during the rotation of the oil reservoir 2, the transmission component 5 converts the rotational motion into the linear motion of the guide 6. When the oil reservoir 2 rotates forward, it drives the guide 6 to rise at a uniform speed; when it rotates in the reverse direction, the guide 6 descends synchronously. During the lifting and lowering process, the guide 6 applies a vertical constraint force to the grease hose 3, forcing the grease hose 3 to wind layer by layer along the spiral path of the guide groove 4.1. Through the synchronous control of mechanical linkage, the offset of the hose winding trajectory is limited within the width of the guide groove 4.1, effectively avoiding loosening caused by gravity or inertia.

[0038] In some of the solutions described above in this application, if the rotational motion between the transmission assembly 5 and the oil storage tank 2 is not precisely matched with the pitch of the guide groove 4.1, misalignment or loosening of the grease hose 3 during winding may occur, affecting the storage effect and equipment stability. To address this, this application further proposes that for every one revolution of the oil storage tank 2 in the forward direction, the transmission assembly 5 drives the guide 6 to rise one pitch above the guide groove 4.1; and for every one revolution of the oil storage tank 2 in the reverse direction, the transmission assembly 5 drives the guide 6 to descend one pitch below the guide groove 4.1.

[0039] As a preferred embodiment, the solution of this application is specifically implemented as follows: The transmission assembly 5 includes a first pulley 5.1, a second pulley 5.2, a transmission belt 5.3, a lead screw 5.4, and a nut 5.5. The first pulley 5.1 is coaxially fixed to the oil storage tank 2, and the second pulley 5.2 is coaxially fixed to the lead screw 5.4. The transmission belt 5.3 drivesly connects the first pulley 5.1 and the second pulley 5.2. The lead screw 5.4 is rotatably connected to the frame 1, and the nut 5.5 is sleeved on the outside of the lead screw 5.4 and threadedly connected to the lead screw 5.4. The guide 6 is fixed to the nut 5.5 and slidably connected to the frame 1 in a vertical direction.

[0040] Specifically, the first pulley 5.1 can be coaxially fixed to the oil reservoir 2 via a key connection or an interference fit. The second pulley 5.2 can be coaxially fixed to the lead screw 5.4 via a key connection or an interference fit. The lead screw 5.4 can be rotatably connected to the frame 1 via a bearing housing. The nut 5.5 can be fixedly connected to the guide member 6 via bolts.

[0041] Therefore, when the oil storage tank 2 rotates, the first pulley 5.1 rotates accordingly. Through the transmission belt 5.3, the second pulley 5.2 and the lead screw 5.4 also rotate. The rotational motion of the lead screw 5.4 is converted into the linear motion of the nut 5.5 through its threaded engagement with the nut 5.5, thereby driving the guide 6 to move up and down.

[0042] Through the above technical solution, this application achieves precise conversion between the rotational motion of the oil storage tank 2 and the linear motion of the guide member 6. The pulley drive mechanism simplifies the power transmission process and improves transmission efficiency. The screw 5.4 and nut 5.5 mechanism precisely converts the rotational motion into linear motion, ensuring the synchronization of the lifting amplitude of the guide member 6 with the number of rotations of the oil storage tank 2. In addition, the self-locking characteristic of the screw 5.4 and nut 5.5 mechanism prevents accidental displacement of the guide member 6 in the non-drive state, improving motion stability. The overall transmission structure is simple and reliable, easy to implement and maintain, and effectively solves the problems of complex transmission mechanism design and low motion conversion efficiency.

[0043] In some of the solutions described above in this application, the transmission assembly 5 is proposed to achieve synchronous rotation of the oil reservoir 2 and lifting of the guide 6 through the cooperation of pulleys, transmission belt 5.3, lead screw 5.4 and nut 5.5. However, in this process, if there is no precise transmission relationship between the pitch of the guide groove 4.1 and the pitch of the lead screw 5.4, or if the structure of the transmission assembly 5 cannot flexibly adapt to different pitch requirements, the lifting of the guide 6 will not accurately correspond to the winding trajectory of the grease hose 3, thereby affecting the storage effect of the grease hose 3.

[0044] To address this, this application further proposes that the pitch of the guide groove 4.1 is L1, the pitch of the lead screw 5.4 is L2, and the transmission ratio of the first pulley 5.1 and the second pulley 5.2 is n1:n2, where L2:L1 = n1:n2. The pitch L1 of the guide groove 4.1 and the pitch L2 of the lead screw 5.4 are linked through the transmission ratio n1:n2, so that the rotation of the lead screw 5.4 directly corresponds to the change in the pitch height of the guide groove 4.1. For example, when the transmission ratio is 1:1, the pitch L2 of the lead screw 5.4 is equal to the pitch L1 of the guide groove 4.1; when the transmission ratio is 2:1, the pitch L2 of the lead screw 5.4 can be twice the pitch L1 of the guide groove 4.1.

[0045] Specifically, when the oil reservoir 2 rotates, it drives the first pulley 5.1 to rotate, which in turn drives the second pulley 5.2 to rotate via the transmission belt 5.3, thereby driving the lead screw 5.4 to rotate. Driven by the lead screw 5.4, the nut 5.5 moves axially, causing the guide 6 to rise and fall. By setting the transmission relationship L2:L1=n1:n2, for every revolution of the oil reservoir 2, the lead screw 5.4 rotates n2 / n1 revolutions, and the nut 5.5 moves a distance of L2(n2 / n1). Since the pitch of the guide groove 4.1 is L1, L2(n2 / n1)=L1, i.e., L2:L1=n1:n2. Therefore, the rising and falling height of the guide 6 is perfectly synchronized with the pitch of the guide groove 4.1, ensuring that the grease hose 3 always conforms to the spiral trajectory of the guide groove 4.1 during winding.

[0046] Understandably, since the structure of transmission component 5 can be flexibly replaced—for example, using a gear and rack to replace lead screw 5.4 and nut 5.5, or using a gear assembly to replace pulley drive—this solution has good adaptability and can meet the synchronization requirements under different mechanical structures, improving the versatility and reliability of the grease machine. When using a gear and rack to replace lead screw 5.4 and nut 5.5, the number of rotations of the gear must satisfy the equivalent relationship L1=L2*(n2 / n1) with the movement distance of the rack. For example, each rotation of the gear drives the rack to move a distance L2, and the transmission ratio n1:n2 still maintains the ratio L2:L1. When the pulley is replaced with a gear assembly, the gear tooth ratio must be consistent with the original transmission ratio. For example, the first gear has n1 teeth, and the second gear has n2 teeth. Through the above design, different transmission mechanisms can achieve precise matching between the rotation of the oil reservoir 2 and the lifting of the guide 6, avoiding hose twisting or loosening, improving storage reliability and structural adaptability.

[0047] In some of the solutions described above in this application, the oil storage tank 2 needs to be rotated to achieve the winding and storage of the grease hose 3. However, if the rotation of the oil storage tank 2 relies on manual operation or indirect drive from an external power source, it will result in inconvenient operation, low efficiency, and difficulty in achieving stable synchronization with the winding action of the grease hose 3.

[0048] As a preferred embodiment, the solution of this application is specifically implemented as follows: A first driving member 7 for driving the oil storage tank 2 to rotate is provided on the frame 1. The first driving member 7 can be a motor, and the output shaft of the motor is coaxially connected to the axis of the oil storage tank 2. Further, the motor can be installed at the bottom or side of the frame 1 and connected to the oil storage tank 2 through a transmission mechanism such as a gear set or a pulley set to adapt to different installation space requirements.

[0049] Through the above technical solution, this application achieves automated rotation of the oil storage tank 2 without relying on manual operation or complex external transmission mechanisms. Specifically, the first driving component 7 directly drives the oil storage tank 2 to rotate around its own axis, making the winding process of the grease hose 3 smoother and avoiding the problem of the grease hose 3 coming loose. In addition, this direct drive method simplifies the overall structure and improves the reliability and service life of the equipment.

[0050] This application further proposes that the first driving component 7 and the oil storage tank 2 are connected by a clutch assembly 12. The clutch assembly 12 can be configured as an electromagnetic clutch, a mechanical friction clutch, or a hydraulic clutch, with its input end coaxially connected to the output shaft of the first driving component 7 and its output end connected to the drive shaft of the oil storage tank 2 via a coupling.

[0051] This application further proposes that the guide 6 is provided with a first clamping wheel 8, a second clamping wheel 9 and a second driving member 10, the second driving member 10 drives the first clamping wheel 8 to rotate, and the first clamping wheel 8 and the second clamping wheel 9 clamp the grease hose 3.

[0052] The axes of the first clamping wheel 8 and the second clamping wheel 9 can be arranged in parallel, and the gap between them can be adjusted according to the outer diameter of the hose. The power output shaft of the second drive component 10 is connected to the first clamping wheel 8 through a coupling or gearbox, and the drive speed can be matched with the hose conveying speed.

[0053] Specifically, during the release of the grease hose 3, the first clamping wheel 8 is driven to rotate by the second drive member 10, applying radial pressure to the hose through the clamping area formed with the second clamping wheel 9. This clamping pressure generates sufficient friction between the hose surface and the clamping wheels, thereby converting the rotational motion into linear movement of the hose. Releasing the grease hose 3 through the first clamping wheel 8 avoids the grease hose 3 from becoming loose due to the rotation of the oil reservoir 2.

[0054] This application further proposes that the guide 6 is provided with a third drive member 11, which drives the first clamping wheel 8 or the second clamping wheel 9 to move, so that the first clamping wheel 8 and the second clamping wheel 9 move closer or further apart, and clamp or release the grease hose 3.

[0055] The third driving component 11 can be selected from an electric push rod, a hydraulic cylinder, or a pneumatic actuator. Its output end is connected to the bearing seat of the first clamping wheel 8 via a mounting base. The mounting base slides along a linear guide rail to maintain stable movement. The wheel surface distance between the first clamping wheel 8 and the second clamping wheel 9 can be adjusted from 5 to 50 mm to accommodate grease hoses 3 of different diameters. When the third driving component 11 pushes the first clamping wheel 8 towards the second clamping wheel 9, the gap between the two wheels decreases to match the outer diameter of the hose, at which point the hose is clamped between the wheel surfaces. When the driving component retracts, the gap increases to 1.2-1.5 times the outer diameter of the hose, allowing the hose to be freely pulled out.

[0056] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
