Description

Technical Field

[0001] This utility model belongs to the field of single-point lubrication of mechanical equipment. Specifically, this utility model relates to a single-point lubrication oil injector. Background Technology

[0002] The cement industry has high requirements for equipment lubrication, especially for rotating equipment such as bearings and motors in rotary kilns and coal mills. Currently, the lubrication situation in cement plants is very poor; over 60% of equipment failures are caused by poor lubrication, and over 80% of abnormal wear of parts is due to abnormal wear caused by inadequate lubrication. The main reason for this situation is that most lubrication points in the cement industry still rely on manual lubrication by operators. Operators apply lubricant manually or use grease pumps or grease guns. This results in numerous lubrication points on the production floor, a large workload for manual lubrication, and high labor costs.

[0003] To address the aforementioned issues, patent document 112228758A discloses a method for using a single-point lubrication device for motor bearings. After the oil supply device and the oil injection device are connected, the oil outlet of the single-point lubrication device is fixedly connected to the oil injection port of the mechanical equipment. When the operating time of the single-point lubrication device reaches the set time interval for oil supply or time-cycle oil supply, the execution module starts the lead screw stepper motor to rotate the lead screw and drive the hollow tube piston oil pump to reciprocate. The hollow tube piston oil pump injects oil into the oil injection hole of the mechanical equipment according to the metering. The single-point lubrication device provides oil supply lubrication at the set time interval or time cycle, but it cannot solve the aforementioned problems. Utility Model Content

[0038] like Figure 1 , Figure 2 as well as Figure 3 As shown, the single-point lubrication injector provided by this utility model includes an oil cup assembly 10 and an injection structure 20 disposed on the oil cup assembly 10. The oil cup assembly 10 includes an oil cup body 11 and a push seat 12. The push seat 12 is movably disposed inside the oil cup body 11.

[0039] Figure 4 This is a schematic diagram of the structure of the oil cup body in an embodiment of this utility model; Figure 5 This is a schematic diagram of the oil cup body in a top view of an embodiment of this utility model.

[0040] like Figure 4 and Figure 5 As shown, the oil cup body 11 is a cylindrical cup with one open end. The bottom of the oil cup body 11 is funnel-shaped, and a threaded connector 111 is provided at the bottom of the oil cup body 11. The threaded connector 111 is used to connect to the lubrication point of the production equipment, thereby facilitating the fixed installation of the single-point lubrication injector provided by this utility model on the lubrication point of the production equipment.

[0042] like Figure 6 and Figure 7 As shown, the bottom of the push seat 12 is a frustum-shaped cone with a central bulge, which fits and conforms to the bottom of the oil cup body 11. The push seat 12 has a circular mesh reinforcing rib 121 inside, which enhances the structural strength of the push seat 12 and ensures stable dispensing of lubricating grease. The push seat 12 has a threaded hole 122 for connection to the oil injection structure 20.

[0043] Figure 8 This is a schematic diagram of the base, drive motor, and rotating screw in the oil injection structure of this utility model embodiment.

[0044] like Figure 8 As shown, the oil filling structure 20 includes a base 21, a drive motor 22, and a rotating screw 23. The base 21 is connected to the oil cup body 11. The drive motor 22 is mounted on the base 21, and the motor shaft of the drive motor 22 is connected to the rotating screw 23. The drive motor 22 can drive the rotating screw 23 to rotate. The rotating screw 23 is adapted to the threaded hole 122 on the push seat 12. The push seat 12 is movably mounted on the rotating screw 23 through threaded engagement. The drive motor 22 drives the rotating screw 23 to rotate. Through the threaded engagement, the rotational motion of the rotating screw 23 is converted into the linear motion of the push seat 12, so that the push seat 12 can move linearly along the rotating screw 23, pressing out the lubricating grease in the oil cup body 11 through the threaded connector 111. This facilitates the lubrication of production equipment lubrication points and effectively reduces the labor cost of lubrication.

[0045] Figure 9 This is a schematic diagram of the base structure in an embodiment of this utility model; Figure 10 This is a schematic diagram of the base in the front view direction in an embodiment of this utility model; Figure 11 This is a structural schematic diagram of the base in a bottom view of an embodiment of this utility model.

[0046] like Figure 9 , Figure 10 as well as Figure 11 As shown, a first locking flange 211 is provided on the side of the base 21 near the oil cup body 11. The first locking flange 211 is annular and located on the outer circumferential surface of the base 21. The bottom of the base 21 is provided with a mounting hole 212 for mounting the drive motor 22. A screw passes through the mounting hole and connects to the drive motor 22, thereby fixing the drive motor 22. The bottom of the base 21 is also provided with a connecting hole 213 for the motor shaft of the drive motor 22 to pass through and connect with the rotating screw 23.

[0047] Figure 12 This is a schematic diagram of the locking ring in an embodiment of this utility model.

[0048] like Figure 12 As shown, the single-point lubrication injector provided by this utility model also includes a locking ring 30. The locking ring 30 is used to lock and connect the oil cup body 11 and the base 21. The inner wall of the locking ring 30 is provided with a threaded groove 31 that matches the threaded protrusion 112. The locking ring 31 is connected to the oil cup body 11 through the threaded groove 31 and the threaded protrusion 112 threadedly engaged. The locking ring 31 has a second locking flange 32 on one side edge near the base 21 that matches the first locking flange 211. The second locking flange 32 is annular. When the locking ring 30 is connected to the oil cup body 11, the threaded protrusion 112 is screwed into the threaded groove 31, and the second locking flange 32 abuts against the first locking flange 211, thereby pressing the base 21 onto the oil cup body 11. This can prevent relative rotation between the base 21 and the oil cup body 11, ensuring the stability and reliability of the lubricating grease filling process. The oil cup body 11 and the base 21 are connected by the locking ring 30, which makes it easy to disassemble and assemble, and to replenish the lubricating grease in the oil cup body 11 after it is depleted.

[0049] like Figure 5 As shown, a positioning groove 113 is provided on the edge of the oil cup body 11 near the base 21. The positioning grooves 113 are evenly distributed on the edge of the oil cup body 11, such as... Figure 10 As shown, a positioning protrusion 214 is provided on the side of the first locking flange 211 near the oil cup body 11. The positioning protrusions 214 are evenly distributed on the first locking flange 211 and correspond one-to-one with the positioning grooves 113. The base 21 is connected to the oil cup body 11. The part of the base 21 below the first locking flange 211 is engaged in the oil cup body 11, so that the positioning protrusions 214 on the first locking flange 211 are engaged in the positioning grooves 113 on the edge of the oil cup body 11. This further prevents relative rotation between the base 21 and the oil cup body 11, ensuring the stability and reliability of the lubricating grease filling process.

[0050] Figure 13 This is a schematic diagram of the counting component in an embodiment of this utility model.

[0051] like Figure 13As shown, the counting assembly 40 includes a counting gear 41 and a micro switch 42. The micro switch 42 is mounted on the base 21 and has a drive rod 43. The counting gear 41 is positioned between the motor shaft of the drive motor 22 and the rotating screw 23. The motor shaft of the drive motor 22 drives the rotating screw 23 to rotate via the counting gear 41, enabling the rotating screw 23 and the counting gear 41 to rotate synchronously. The counting gear 41 has eight ratchet teeth 44 evenly distributed on it. When the counting gear 41 rotates, the ratchet teeth... The tooth 44 abuts against the drive rod 43 and triggers the micro switch 42. Each time the counting gear 41 rotates once, the rotating screw 23 rotates 360°, causing the push seat 12 to move downward a fixed distance. During the rotation of the counting gear 41, each of the eight ratchet teeth 44 triggers the micro switch 42 once. The micro switch 42 sends an electrical signal every eight triggers, which facilitates the control of the amount and cycle of lubricating grease, avoids the situation of too much or too little lubricating grease, avoids lubricating grease waste, and reduces the labor cost of lubricating grease.

[0052] Figure 14 This is a schematic diagram of the counting gear structure in an embodiment of this utility model. Figure 1 ; Figure 15 This is a schematic diagram of the counting gear structure in an embodiment of this utility model. Figure 2 .

[0053] like Figure 14 and Figure 15 As shown, a first connecting groove 411 is provided on the side of the counting gear 41 near the drive motor 22. The first connecting groove 411 is adapted to the motor shaft of the drive motor 22, and the motor shaft of the drive motor 22 is locked in the first connecting groove 411. A second connecting groove 412 is provided on the side of the counting gear 41 near the rotating screw 23. A hexagonal protrusion 231 is provided on the end of the rotating screw 23 near the counting gear 41. The second connecting groove 412 is hexagonal and adapted to the hexagonal protrusion 231, so as to facilitate the connection between the counting gear 41 and the rotating screw 23. Thus, the rotating screw 23 and the motor shaft of the drive motor 22 are connected through the counting gear 41, so that the rotating screw 23 and the counting gear 41 can rotate synchronously, which improves the stability and reliability of the lubricating grease filling process, ensures the normal operation of the counting component 40, and effectively ensures the accuracy of controlling the amount of lubricating grease filled.

[0054] An anti-reverse shim is also provided between the counting gear 41 and the base 21. The anti-reverse shim is set between the counting gear 41 and the base 21 to prevent the counting gear 41 from reversing, which further improves the stability and reliability of the lubricating grease filling process, further ensures the normal operation of the counting component 40, and effectively ensures the accuracy of controlling the amount of lubricating grease added.

[0055] Figure 16 This is a schematic diagram of the power supply and PCB control circuit board in the oil injection structure of an embodiment of this utility model.

[0056] like Figure 16 As shown, the oil injection structure 20 also includes a power supply 24 and a PCB control circuit board 25. The power supply 24 is connected to the PCB control circuit board 25, which in turn is connected to the drive motor 22. This allows the power supply 24 to provide power to the drive motor 22 and the PCB control circuit board 25, ensuring their normal operation. The power supply 24 uses dry cell batteries for easy replacement. The PCB control circuit board 25 is connected to a micro switch 42, which receives electrical signals from the micro switch 42. This allows for easy monitoring of the lubricating grease injection amount, injection time, and lubrication fault information of the single-point lubrication injector, thereby effectively reducing labor costs and effectively monitoring the lubrication status of multiple production equipment lubrication points on the production site.

[0057] Figure 17 This is a schematic diagram of the structure of the protective cover in an embodiment of this utility model.

[0058] like Figure 17 As shown, the single-point lubrication injector provided by this utility model also includes a protective cover 50. The protective cover 50 is set on the locking ring 30 and covers the base 21. It can protect the oil injection structure 20 and the drive motor 22, PCB control circuit board 25 and other components inside the base 21, prevent dust and other impurities from entering and damaging the components, and improve the reliability and service life of the structure.

[0059] A pressure cover 26 is provided on the side of the base 21 near the protective cover 50. A compression spring 27 is provided between the pressure cover 26 and the protective cover 50. One end of the compression spring 27 is connected to the pressure cover 26 and the other end is connected to the protective cover 50. When the compression spring 27 is in a compressed state, the pressure cover 26 is pressed tightly onto the base 21, which further prevents dust and other impurities from entering the interior of the base 21 and damaging the components, thereby further improving the reliability and service life of the structure.

[0060] like Figure 12 As shown, the locking ring 30 is provided with a positioning flange 33, the positioning flange 33 is provided with a positioning notch 34, and the inner wall of the protective cover 50 is provided with a positioning protrusion 51 that matches the positioning notch 34. The positioning protrusion 51 is engaged in the positioning notch 34, thereby securing the protective cover 50 onto the locking ring 30 for easy disassembly.

[0061] like Figure 4As shown, the oil cup body 11 is provided with a first mounting groove 114, and a first sealing ring 60 is provided in the first mounting groove 114. The first sealing ring 60 is located between the oil cup body 11 and the protective cover 50, which can further enhance the sealing performance, prevent dust and other impurities from entering and damaging the components, and improve the reliability and service life of the structure.

[0062] like Figure 6 As shown, the push seat 12 is provided with a second mounting groove 124. The two second mounting grooves 124 are distributed on the edge of the push seat 12. A second sealing ring 70 is provided in each of the two second mounting grooves 124. The second sealing ring 70 is located between the inner wall of the push seat 12 and the oil cup body 11, which can enhance the sealing between the push seat 12 and the oil cup body 11, prevent lubricating grease from leaking from the push seat 12 and the oil cup body 11, ensure that the lubricating grease can be smoothly pressed out from the threaded connector 111, and improve the stability of lubricating grease filling.

[0063] like Figure 1 and 3 As shown, a connecting seat 80 is provided at one end of the oil cup body 11 away from the oil injection structure 20. The connecting seat 80 is funnel-shaped and is connected to the threaded connector 111 by a threaded fit. An extension connector 81 is provided on the connecting seat 80. The connecting seat 80 is installed on the lubrication point of the production equipment through the extension connector 81, so as to facilitate the connection of the single-point lubrication oil injector provided by this utility model to the lubrication point of the production equipment and facilitate disassembly and assembly.

[0064] When adding lubricating grease using the single-point lubrication injector provided by this utility model, the lubricating grease is added into the oil cup body 11. The push seat 12 is pressed into the oil cup body 11, and the rotating screw 23 is screwed into the threaded hole 122 of the push seat 12. The base 21 is installed, and the hexagonal protrusion 231 at one end of the rotating screw 23 is connected to the second connecting groove 412 of the counting gear 41, thereby connecting the rotating screw 23 and the motor shaft of the drive motor 22. The positioning protrusion 214 on the base 21 is engaged in the positioning groove 113 on the edge of the oil cup body 11, and the locking is completed. Ring 30 is fitted onto oil cup body 11 from one end of base 21, and threaded protrusion 112 is screwed into threaded groove 31, so that the first locking flange 211 of base 21 and the second locking flange 32 of locking ring 30 abut against each other, thereby pressing base 21 onto oil cup body 11. Protective cover 50 is installed on locking ring 30. After assembling the single-point lubrication injector, it is connected to connecting seat 80 through threaded connector 111 on oil cup body 11, thereby connecting the lubrication point of production equipment, facilitating automatic lubrication, and helping to reduce labor costs.

[0065] During the lubrication process, the PCB control circuit board 25 controls the drive motor 22 to start. The drive motor 22 drives the rotating screw 23 to rotate through the counting gear 41. The counting gear 41 and the rotating screw 23 rotate synchronously. The rotational motion of the rotating screw 23 is converted into the linear motion of the push seat 12, thereby squeezing the lubricating grease in the oil cup body 11 out of the threaded connector 111. When the counting gear 41 rotates, the ratchet 44 abuts against the drive rod 43 and triggers the micro switch 42. For each rotation of the counting gear 41, the rotating screw 23 rotates 360°, causing the pusher seat 12 to move downward a fixed distance. During one rotation of the counting gear 41, each of the eight ratchet teeth 44 triggers the micro switch 42 once. The micro switch 42 transmits an electrical signal every eight triggers. The PCB control circuit board 25 can receive the electrical signal transmitted by the micro switch 42. Since the rotating screw 23 rotates 360° for each rotation of the counting gear 41, the downward distance of the pusher seat 12 is fixed, and the diameter of the oil cup body 11 is also fixed, the amount of lubricating grease squeezed out for each rotation of the counting gear 41 is constant. This allows the PCB control circuit board 25 to control the number of rotations of the counting gear 41 and the rotating screw 23 and the timing of rotation based on the electrical signal transmitted by the micro switch 42, thereby facilitating the control of the lubricating grease filling amount and filling cycle.

[0066] Based on the actual production site conditions and the specifications of the production equipment, the actual daily lubricant consumption of the production equipment is determined. This allows the PCB control circuit board 25 to control the operation of the drive motor 22, enabling the drive motor 22 to start and rotate at a set time each day, driving the counting gear 41 and the rotating screw 23 to rotate a fixed number of times. This controls the amount and cycle of lubricant added, preventing excessive or insufficient lubricant addition, avoiding lubricant waste, and reducing the labor cost of lubricant addition.

[0067] The role and effect of the embodiments

[0068] The single-point lubrication injector provided by this utility model includes an oil cup assembly 10 and an oil injection structure 20 disposed on the oil cup assembly 10.

The oil injection structure 20 can control the amount of lubricating grease added and the injection cycle by controlling the moving distance of the push seat 12, thereby avoiding excessive or insufficient lubricating grease addition, avoiding lubricating grease waste, and effectively reducing the labor cost of lubricating grease addition.

[0069] When adding lubricating grease using the single-point lubrication injector provided by this utility model, the lubricating grease is added into the oil cup body 11.

The base 21 is installed, and the hexagonal protrusion 231 at one end of the rotating screw 23 is connected to the second connecting groove 412 of the counting gear 41, thereby connecting the rotating screw 23 and the motor shaft of the drive motor 22. The positioning protrusion 214 on the base 21 is engaged in the positioning groove 113 on the edge of the oil cup body 11, and the locking is completed. Ring 30 is fitted onto oil cup body 11 from one end of base 21, and threaded protrusion 112 is screwed into threaded groove 31, so that the first locking flange 211 of base 21 and the second locking flange 32 of locking ring 30 abut against each other, thereby pressing base 21 onto oil cup body 11. Protective cover 50 is installed on locking ring 30. After assembling the single-point lubrication injector, it is connected to connecting seat 80 through threaded connector 111 on oil cup body 11, thereby connecting the lubrication point of production equipment, facilitating automatic lubrication, and helping to reduce labor costs.

[0070] During the lubrication process, the PCB control circuit board 25 controls the drive motor 22 to start. The drive motor 22 drives the rotating screw 23 to rotate through the counting gear 41. The counting gear 41 and the rotating screw 23 rotate synchronously. The rotational motion of the rotating screw 23 is converted into the linear motion of the push seat 12, thereby squeezing the lubricating grease in the oil cup body 11 out of the threaded connector 111. When the counting gear 41 rotates, the ratchet 44 abuts against the drive rod 43 and triggers the micro switch 42. For each rotation of the counting gear 41, the rotating screw 23 rotates 360°, causing the pusher seat 12 to move downward a fixed distance. During one rotation of the counting gear 41, each of the eight ratchet teeth 44 triggers the micro switch 42 once. The micro switch 42 transmits an electrical signal every eight triggers. The PCB control circuit board 25 can receive the electrical signal transmitted by the micro switch 42. Since the rotating screw 23 rotates 360° for each rotation of the counting gear 41, the downward distance of the pusher seat 12 is fixed, and the diameter of the oil cup body 11 is also fixed, the amount of lubricating grease squeezed out for each rotation of the counting gear 41 is constant, thus facilitating the control of the lubricating grease filling amount and filling cycle.

[0071] Based on the actual production site conditions and the specifications of the production equipment, the actual daily lubricant consumption of the production equipment is determined. This allows the PCB control circuit board 25 to control the operation of the drive motor 22, enabling the drive motor 22 to start and rotate at a set time each day, driving the counting gear 41 and the rotating screw 23 to rotate a fixed number of times. This controls the amount and cycle of lubricant added, preventing excessive or insufficient lubricant addition, avoiding lubricant waste, and reducing the labor cost of lubricant addition.
