[0020] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0021] The following description sets forth many specific details to facilitate a thorough understanding of the present application. However, the present application may also be implemented in other ways than those described herein, and therefore, the scope of protection of the present application is not limited by the specific embodiments disclosed below. It should be noted that the embodiments of the present application and the features of each embodiment may be combined with each other unless there is a conflict.

[0022] A lubricating grease adding device includes a support frame 1 and an oil storage tank 2 arranged on the top of the support frame 1. A refueling port is provided on the top of the oil storage tank 2. An oil outlet pipe 3 is connected to the bottom of the oil storage tank 2. A quantitative oil outlet device is provided on the oil outlet pipe 3. The quantitative oil outlet device is arranged on opposite sides of the oil outlet pipe 3 through a mounting frame 4. The quantitative oil outlet device includes a driving component 5 and a control component 6. The driving component 5 is rollingly connected to the control component 6. The control component 6 extends to the inside of the oil outlet pipe 3 along the longitudinal direction. A through hole is opened in the oil outlet pipe 3 corresponding to the control component 6.

[0023] Furthermore, the control component 6 includes a connecting block 61, which is provided with a semicircular protrusion 62 at one end facing the drive component 5, and the semicircular protrusion 62 is in contact with the drive component 5. An oil film disk 63 is provided at the other end, and the oil film disk 63 is located in the oil outlet pipe 3 and in contact with the lubricating oil in the oil outlet pipe 3.

[0024] Furthermore, the driving assembly 5 includes a motor 51 and a cam 52 connected to the driving shaft of the motor 51 . The cam 52 is in rolling connection with the semicircular protrusion 62 . A pulley 53 is installed on the driving shaft axially away from the cam 52 .

[0025] Furthermore, the driving assembly 5 also includes a spring 54, which is located at the upper end of the driving shaft of the motor 51 and is symmetrically arranged on both sides of the cam 52. One end of the spring 54 is connected to the mounting bracket 4, and the other end is connected to the connecting block 61.

[0026] When using the adding device in the present application, first adjust the height of the oil outlet pipe 3 through the electric telescopic rod 7, then connect the oil outlet pipe 3 to the oil outlet of the oil storage tank 2 and the oil outlet pipe 3 through bolts, and then open the sealing cover to add oil into the oil storage tank 2. The oil flows downward along the oil outlet pipe 3 under the action of gravity.

[0027] When the oil flows to the position of the quantitative oil outlet device, when the device needs to be adjusted, the motor 51 is started, and the driving shaft of the motor 51 drives the cam 52 to rotate, and at the same time drives the pulley 53 on the other side to rotate. The cam 52 contacts the semicircular protrusion 62, causing the connecting block 61 to move horizontally, thereby driving the oil film disk 63 located in the oil outlet pipe 3 to move horizontally to control the oil outflow area. According to the different positions of the cam 52 rotation, the displacement of the oil film disk 63 is also different. The transmission of the farther axis is realized through the transmission of the belt and the pulley 53, so that the control device located on the other side of the oil outlet pipe 3 can also undergo the same movement.

[0028] After the adjustment is completed, the motor 51 is turned off, and the connecting block 61 is automatically reset under the elasticity of the spring 54 and retracted from the oil outlet pipe 3.

[0029] By adopting the above technical solution, the contact stability between the connecting block 61 and the driving component 5 is increased through the design of the semicircular protrusion 62, and the friction and wear are reduced. The horizontal displacement of the oil film disk 63 accurately controls the outflow of grease, avoiding the problem of insufficient lubrication due to excessive or insufficient lubrication. At the same time, the spring 54 is used to balance the pressure of the driving component 5, ensure the stable contact between the cam 52 and the semicircular protrusion 62, buffer the vibration and impact of the driving system, avoid excessive wear or failure, and the symmetrical setting of the spring 54 increases the balance of the driving system and improves the overall reliability.

[0030] Preferably, the present application uses a motor 51 and a cam 52 device to achieve transmission. In other embodiments, the motor 51 is connected to the control component 6 via a screw drive. The screw can be rotated to push the nut to move axially. The movement of the nut drives the adjustment of the control component 6 (oil film disk 63). Suitable guide devices, such as linear bearings, are provided on both sides of the screw to ensure that the nut moves stably along the axis of the screw. The motor 51 rotates precisely according to a preset step angle. The screw moves axially under the drive of the stepping motor 51. The movement of the nut drives the connection component to perform fine adjustment to achieve control of the oil output.

[0031] Furthermore, the mounting frame 4 is provided with grooves corresponding to the positions of the oil outlet pipe 3 and the driving assembly 5 .

[0032] By adopting the above technical solution, the groove is used to ensure the stable installation of the oil outlet pipe 3 and the drive assembly 5 to avoid loosening caused by vibration. The depth and width of the groove should be designed according to the dimensions of the oil outlet pipe 3 and the drive assembly 5 to ensure a firm connection. The groove provides stable support, prevents the position of the oil outlet pipe 3 and the drive assembly 5 from shifting, and improves the durability of the device.

[0033] Furthermore, a receiving groove is symmetrically provided at the bottom of the support frame 1 , and an electric telescopic rod 7 is installed in the receiving groove. The electric telescopic rod 7 is fixedly connected to the mounting frame 4 .

[0034] Furthermore, an oil level sensor is provided in the middle of the oil storage tank 2 .

[0035] Oil level sensors are used to monitor the amount of grease in the oil tank to prevent the equipment from malfunctioning due to low oil levels. The sensor type can be float, ultrasonic, or capacitive. The most suitable sensor is selected according to the specific application. The oil level sensor ensures the stability of the grease supply and can monitor the grease usage status in real time to avoid equipment failure caused by insufficient or excessive grease.

[0036] Furthermore, a flow regulating valve is provided in the oil outlet pipe 3, and the flow regulating valve is a rotary valve.

[0037] By adopting the above technical solution, the rotary flow control valve changes the flow cross-section by rotation and accurately controls the grease flow. The rotary valve has the characteristics of simple structure and high adjustment accuracy, and can operate stably under different working conditions.

[0038] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0039] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

[0040] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
