Description

Technical Field

[0001] This invention relates to the field of equipment lubrication technology, and in particular to a non-powered synchronous fixed-point lubrication device. Background Technology

[0002] In industries with high hygiene requirements, such as the medical, laboratory, and food processing industries, the use of disposable gloves is generally recommended. This not only avoids cross-infection but also significantly reduces replacement costs. The production process of disposable gloves typically employs a drive chain to power a suspended mold base. The mold base is connected to the drive chain via pins, rotating at different angles at different stages, thus automating the production line process for disposable gloves.

[0003] During actual production and processing, the pins may rust to a certain extent due to the production environment, which may lead to jamming or even seizing of the mold base. A jammed mold base can easily cause serious accidents such as vehicle collisions, resulting in losses of manpower and resources. Moreover, maintenance and replacement will directly affect the production efficiency of disposable gloves. Therefore, it is necessary to add lubricating oil to the pins regularly during the production and processing process. Lubricating oil can effectively prevent pin corrosion, improve the transmission effect between the transmission chain and the mold base, and greatly reduce pin wear, thus extending its service life.

[0004] Currently, there is no dedicated equipment for adding lubricating oil to operating pins. Lubricating oil addition is mostly done manually, and due to the high speed of the machine, multiple workers are usually required to perform intermittent oiling. Manual lubrication is not only labor-intensive, time-consuming, and costly, but it also cannot achieve precise and even application of lubricating oil, easily leading to missed or repeated lubrication of individual pins. Pins that are missed are prone to rust and wear, resulting in a shorter service life; pins that are repeatedly lubricated are prone to oil leakage in the mold base or idle areas, causing contamination of the mold base and idle areas, as well as lubricating oil waste.

[0005] Therefore, developing a simple, low-cost, and high-precision non-powered synchronous fixed-point refueling device is not only of urgent research value, but also has good economic benefits and industrial application potential. This is the driving force and foundation for the completion of this invention. Summary of the Invention

[0006] In order to overcome the deficiencies of the prior art as mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this invention.

[0007] Specifically, the technical problem to be solved by the present invention is to provide a non-powered synchronous fixed-point lubrication device to solve the technical problems of the current manual lubrication method, which is labor-intensive, time-consuming, costly, and unable to achieve precise and uniform lubrication.

[0008] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0009] A non-powered synchronous fixed-point lubrication device includes a frame, on which are provided two lubrication mechanisms for adding lubricating oil to the pins on both sides of the transmission chain. The lubrication mechanism is connected to the oil supply mechanism and is located above the transmission chain and is slidably arranged along the conveying direction of the transmission chain.

[0010] Both sets of refueling mechanisms are equipped with clutch components for transmission connection with the drive chain, and the two sets of refueling mechanisms are connected by a synchronous transmission mechanism. When in refueling mode, one set of refueling mechanisms is connected to the drive chain through its clutch component, and under the action of the synchronous transmission mechanism, the two sets of refueling mechanisms slide in opposite directions, and the sliding displacement rate of the refueling mechanism is consistent with the conveying rate of the drive chain.

[0011] As an improved technical solution, the refueling mechanism includes a mounting plate slidably mounted on the frame, a cylinder-driven lifting top plate slidably mounted on the top of the mounting plate in the vertical direction, and a plurality of refueling pipes mounted on the lifting top plate. The plurality of refueling pipes are arranged sequentially, and the distance between two adjacent refueling pipes is the same as the distance between two adjacent pins. When in the refueling state, the refueling pipes are respectively located directly above the pins.

[0012] As an improved technical solution, the oil supply mechanism includes an oil supply machine, which is connected to the refueling pipe via an oil supply pipe.

[0013] As an improved technical solution, a slide rail is fixedly installed on the frame, and a slider is slidably installed on the slide rail. The slider is fixedly connected to the mounting plate, and the mounting plate is slidably installed on the frame through the slide rail and the slider.

[0014] As an improved technical solution, a guide shaft is slidably mounted on the mounting plate using a linear bearing, the lifting top plate is fixedly mounted on the top of the guide shaft, the cylinder is fixedly mounted on the mounting plate, and the piston shaft end of the cylinder is connected to the lifting top plate.

[0015] As an improved technical solution, the clutch assembly includes a lifting base plate fixedly installed at the bottom end of the guide shaft. A limit hole is formed on the lifting base plate. A clutch stop block is hinged to the lifting base plate at the limit hole position using a safety pin. Both ends of the clutch stop block extend to the upper and lower sides of the lifting base plate, respectively. A first tension spring and a first hydraulic damper are respectively provided on both sides of the top of the clutch stop block. A first mounting block is fixedly installed on the lifting base plate. The first hydraulic damper is hingedly installed on the first mounting block. The piston rod end of the first hydraulic damper is hingedly connected to the top of the clutch stop block. One end of the first tension spring is connected to the lifting base plate, and the other end of the first tension spring is connected to the top of the clutch stop block.

[0016] As an improved technical solution, a second tension spring is provided between the lifting base plate and the mounting plate, one end of the second tension spring is connected to the mounting plate, and the other end of the second tension spring is connected to the lifting base plate.

[0017] As an improved technical solution, a third tension spring is provided between the clutch stop block and the mounting plate. One end of the third tension spring is connected to the mounting plate, and the other end of the third tension spring is connected to the top of the clutch stop block.

[0018] As an improved technical solution, the top end of the refueling pipe is hinged to the lifting top plate, and an elastic reset member is provided between the refueling pipe and the lifting top plate. Under the action of the elastic reset member, the refueling pipe is vertically arranged.

[0019] As a further improved technical solution, the refueling pipe is hinged to the lifting top plate on the side near the direction of movement of the transmission chain using a hinge shaft. The elastic reset component is a fourth tension spring located between the refueling pipe and the lifting top plate. One end of the fourth tension spring is connected to the lifting top plate, and the other end of the fourth tension spring is connected to the other side of the top of the refueling pipe, and the fourth tension spring is in a stretched state.

[0020] As an improved technical solution, the synchronous transmission mechanism includes a plurality of synchronous pulleys rotatably mounted on the frame, a synchronous belt being wound around the plurality of synchronous pulleys, and two mounting plates being fixedly connected to both sides of the synchronous belt respectively.

[0021] As an improved technical solution, the frame is provided with a sensor mounting plate, on which a detection sensor for detecting the pin connecting rod is mounted.

[0022] As an improved technical solution, a second hydraulic buffer is installed at each end of the frame using a second mounting block, and the second hydraulic buffer is respectively configured to correspond to the mounting plate.

[0023] After adopting the above technical solution, the beneficial effects of the present invention are:

[0024] (1) This non-powered synchronous fixed-point refueling device has a simple and compact structure. When it is working, when the detection sensor detects the pin connecting rod, the control system controls the clutch component of the left refueling mechanism to engage and the refueling pipe to move downward according to the set program. The left refueling mechanism maintains a linkage with the transmission chain and moves synchronously forward with the transmission chain. The right refueling mechanism moves in the opposite direction with the transmission chain under the drive of the synchronous transmission mechanism. At this time, the left refueling mechanism starts to refuel the pin on the left side of the transmission chain. Refueling stops before the refueling mechanism finishes moving. After the movement ends, the control system controls the clutch component of the left refueling mechanism to disengage and the refueling pipe to rise and reset. The clutch component of the right refueling mechanism engages and the refueling pipe moves downward. The right refueling mechanism maintains a linkage with the transmission chain and moves synchronously forward with the transmission chain. The left refueling mechanism moves in the opposite direction with the transmission chain under the drive of the synchronous transmission mechanism. At this time, the right refueling mechanism starts to refuel the pin on the right side of the transmission chain. This cycle repeats, thereby realizing fixed-point refueling of the pins on both sides of the transmission chain.

[0025] This non-powered synchronous fixed-point lubrication device can accurately add lubricating oil to the pins on both sides of the transmission chain without the need for an additional power unit. This not only ensures accurate, uniform, and efficient lubrication, but also reduces operating costs and prevents missed or repeated additions, thus avoiding contamination of the mold base and idle areas and saving lubricating oil. It is highly practical.

[0026] (2) The provided refueling mechanism is operated by a cylinder, which drives the lifting top plate and lifting bottom plate to move downward synchronously, thereby driving the refueling pipe and clutch stop block to move downward. The clutch stop block is inserted between the two pin shaft connecting rods. When the pin shaft connecting rods move to abut the clutch stop block, the refueling pipe is located directly above and against the pin shaft to be refueled. The pin shaft connecting rods continue to move and drive the entire refueling mechanism to move synchronously forward with the transmission chain, so that the refueling mechanism and the transmission chain maintain a linked state. During this synchronous follow-up displacement process, the refueling pipe refuels the pin shaft, thereby ensuring that the refueling of the pin shaft is accurate and uniform. After the refueling is completed, the cylinder operates, driving the lifting top plate and lifting bottom plate to move upward synchronously, thereby driving the refueling pipe and clutch stop block to rise and reset. This process is repeated to achieve orderly refueling of the pin shaft.

[0027] (3) The clutch assembly is provided with a limiting through hole on the lifting base plate to limit the swing of the clutch stop. When the clutch assembly is engaged by the cylinder, the clutch stop is inserted between the two pins. After the latter pin moves to contact the clutch stop, it pushes the clutch stop from the initial tilted state to the vertical state. During this process, the first hydraulic damper buffers the force and absorbs the impact energy to ensure stable contact between the pin and the clutch stop, and avoids the safety pin breaking due to excessive impact force when the pin contacts the clutch stop, thus achieving force protection. When the clutch assembly is raised to the disengaged state by the cylinder, the clutch stop disengages from the pin and the first tension spring, and the clutch stop and the first hydraulic damper are reset.

[0028] (4) A second tension spring is provided between the lifting base plate and the mounting plate. If a cylinder air failure occurs, the second tension spring pulls up the lifting base plate to ensure that the clutch stop block is disengaged from the pin connecting rod, thus preventing the vehicle from stalling and achieving fault protection.

[0029] (5) A third tension spring is provided between the clutch stop and the mounting plate. If the clutch stop cannot be lifted due to an accidental failure, the safety pin will break as the force on the clutch stop increases. The clutch stop will be lifted under the action of the third tension spring, releasing the contact with the pin connecting rod, preventing damage to the oiling mechanism and the mold base transmission part, and realizing overload safety protection.

[0030] (6) The refueling pipe is hinged to the lifting top plate and vertically set with the elastic reset component, so that the refueling pipe can rotate and swing along the direction of the transmission chain. If the pin to be refueled has a broken arm or other protruding structure, the refueling pipe can automatically avoid it by rotating and swinging after contact and being subjected to force, thereby avoiding damage to the refueling pipe. After avoiding the force, the refueling pipe can automatically reset to the vertical state so as to carry out normal refueling of the next batch of pins.

[0031] (7) The synchronous transmission mechanism is provided, the synchronous belt can rotate, and the mounting plates of the two sets of refueling mechanisms are fixedly connected to both sides of the synchronous belt, so that one set of refueling mechanism can drive the other set of refueling mechanism to slide in the opposite direction, thereby realizing the reciprocating cyclic displacement of the two sets of refueling mechanisms.

[0032] (8) The detection sensor installed on the frame via the sensor mounting plate can detect the pin connecting rod during the movement and feed the detection signal back to the control system. This ensures that when the control system controls the clutch assembly of the refueling mechanism to connect with the transmission chain, the clutch stop can always be inserted between the two pin connecting rods, and there will be no collision between the clutch stop and the pin connecting rod when it is inserted, which would cause a malfunction. This ensures the operational safety of the refueling device.

[0033] (9) The two ends of the frame are provided with second hydraulic buffers that correspond to the mounting plates respectively. When a fixed-point refueling operation is completed, the second hydraulic buffers can buffer the force when the two refueling mechanisms collide, thereby achieving smooth stopping of the two refueling mechanisms when they move to the end of their stroke.

Detailed Implementation

[0043] The present invention will be further described below with reference to specific embodiments. However, the uses and purposes of these exemplary embodiments are only for illustrating the present invention and do not constitute any limitation on the actual scope of protection of the present invention, nor are they intended to limit the scope of protection of the present invention to these embodiments.

[0044] Example 1

[0045] like Figures 1 to 7 As shown in the figure, this embodiment provides a non-powered synchronous fixed-point lubrication device, including a frame 1. The frame 1 is provided with two sets of lubrication mechanisms for adding lubricating oil to the pins 27 on both sides of the transmission chain 25. The lubrication mechanism is connected to the oil supply mechanism and is located above the transmission chain 25 and is slidably arranged along the conveying direction of the transmission chain 25.

[0046] Both refueling mechanisms are equipped with clutch components for transmission connection with the transmission chain 25, and the two refueling mechanisms are connected by a synchronous transmission mechanism. When in refueling mode, one of the refueling mechanisms is connected to the transmission chain 25 through its clutch component, and under the action of the synchronous transmission mechanism, the two refueling mechanisms slide in opposite directions. The sliding displacement rate of the refueling mechanism is consistent with the conveying rate of the transmission chain 25.

[0047] The refueling mechanism includes a mounting plate 2 that is slidably mounted on the frame 1. A lifting top plate 7 driven by a cylinder 5 is slidably mounted on the top of the mounting plate 2 in the vertical direction. Several refueling pipes 8 are installed on the lifting top plate 7. The several refueling pipes 8 are arranged in sequence, and the distance between two adjacent refueling pipes 8 is the same as the distance between two adjacent pins 27. When in the refueling state, the refueling pipes 8 are located directly above the pins 27.

[0048] The lubrication pipe 8 can be equipped with multiple lubrication nozzles as needed. The number of lubrication pipes 8 and the stroke of the lubrication mechanism can be reasonably set according to the number of lubrication pins and the lubrication time in one operation. By setting the corresponding number of lubrication pipes and the stroke of the lubrication mechanism, different lubrication methods can be achieved. For example, if each lubrication mechanism is equipped with 6 lubrication pipes and the stroke of the lubrication mechanism is the distance between 3 pins, the device can complete the lubrication of all pins in one operation during the operation of the transmission chain. If each lubrication mechanism is equipped with 3 lubrication pipes and the stroke of the lubrication mechanism is the distance between 3 pins, the device can lubricate 3 pins at a time during the operation of the transmission chain. That is, lubricate 3 pins and leave 3 pins empty. When the transmission chain returns to the device's position, the device will lubricate the unlubricated pins, thus achieving the lubrication method of completing the lubrication of all pins in two rotations of the transmission chain. This device can achieve different lubrication methods by flexibly setting the number of lubrication pipes and the stroke of the lubrication mechanism, thereby meeting the needs of different users.

[0049] The oil supply mechanism includes an oil supply machine 9, which is connected to a refueling pipe 8 via an oil supply pipe. When the oil supply machine 9 operates, it controls whether or not refueling is carried out through the refueling pipe 8. In this embodiment, the oil supply machine 9 can be a commercially available product. Since oil supply machines are generally understood by those skilled in the art, they will not be described in detail here. In addition, the oil supply pipe connecting the oil supply machine 9 and the refueling pipe 8 is not shown in the accompanying drawings.

[0050] To achieve smooth sliding displacement of the refueling mechanism, a slide rail 3 is fixedly installed on the frame 1, and a slider 4 is slidably installed on the slide rail 3. The slider 4 is fixedly connected to the mounting plate 2, and the mounting plate 2 is slidably installed on the frame 1 through the slide rail 3 and the slider 4.

[0051] To achieve smooth vertical lifting of the lifting top plate 7, a guide shaft 6 is slidably mounted on the mounting plate 2 using a linear bearing. The lifting top plate 7 is fixedly mounted on the top of the guide shaft 6. The cylinder 5 is fixedly mounted on the mounting plate 2, and the piston shaft end of the cylinder 5 is connected to the lifting top plate 7.

[0052] The provided refueling mechanism involves cylinder 5 operating to drive the lifting top plate 7 and lifting bottom plate 10 to move downwards synchronously, thereby causing the refueling pipe 8 and clutch stop 12 to move downwards. The clutch stop 12 is inserted between the two pin shaft connecting rods 26. When the pin shaft connecting rods 26 move to abut the clutch stop 12, the refueling pipe 8 is positioned directly above and against the pin shaft 27 to be refueled. The pin shaft connecting rods 26 continue to move, driving the entire refueling mechanism to move synchronously forward with the transmission chain 25, thus maintaining the refueling mechanism and the transmission chain 25 in a linked state. During this synchronous following displacement process, the refueling pipe 8 refuels the pin shaft 27, thereby ensuring accurate and uniform refueling of the pin shaft 27. After refueling is completed, cylinder 5 operates to drive the lifting top plate 7 and lifting bottom plate 10 to move upwards synchronously, thereby causing the refueling pipe 8 and clutch stop 12 to rise and reset. This process is repeated to achieve orderly refueling of the pin shaft 27.

[0053] The clutch assembly includes a lifting base plate 10 fixedly installed at the bottom end of the guide shaft 6. The lifting base plate 10 has a limit hole 1001. A clutch stop block 12 is hinged to the lifting base plate 10 at the limit hole 1001 using a safety pin 11. The two ends of the clutch stop block 12 extend to the upper and lower sides of the lifting base plate 10, respectively. A first tension spring 13 and a first hydraulic buffer 15 are respectively provided on the top two sides of the clutch stop block 12. A first mounting block 14 is fixedly installed on the lifting base plate 10. The first hydraulic buffer 15 is hinged to the first mounting block 14. The piston rod end of the first hydraulic buffer 15 is hinged to the top of the clutch stop block 12. One end of the first tension spring 13 is connected to the lifting base plate 10, and the other end of the first tension spring 13 is connected to the top of the clutch stop block 12.

[0054] The clutch assembly is equipped with a limiting through hole 1001 on the lifting base plate 10 to limit the swing of the clutch stop 12. When the cylinder 5 drives the clutch assembly to the engaged state, the clutch stop 12 is inserted between the two pin connecting rods 26. After the latter pin connecting rod 26 moves to contact the clutch stop 12, it pushes the clutch stop 12 from the initial tilted state to the vertical state. During this process, the first hydraulic buffer 15 buffers the force and absorbs the impact energy to ensure stable contact between the pin connecting rod 26 and the clutch stop 12, and to prevent the safety pin 11 from breaking due to excessive impact force when the pin connecting rod 26 contacts the clutch stop 12, thus achieving force protection. When the cylinder 5 drives the clutch assembly to rise to the disengaged state, the clutch stop 12 disengages from the pin connecting rod 26, and the clutch stop 12 and the first hydraulic buffer 15 are reset under the action of the first tension spring 13.

[0055] In this embodiment, a second tension spring 16 is provided between the lifting base plate 10 and the mounting plate 2. One end of the second tension spring 16 is connected to the mounting plate 2, and the other end of the second tension spring 16 is connected to the lifting base plate 10.

[0056] In this embodiment, two second tension springs 16 are provided, and the two second tension springs 16 are correspondingly arranged at both ends of the lifting base plate 10.

[0057] A second tension spring 16 is provided between the lifting base plate 10 and the mounting plate 2. If the cylinder 5 fails to supply air, the second tension spring 16 pulls up the lifting base plate 10 to ensure that the clutch stop block 12 is disengaged from the pin connecting rod 26, thus preventing the vehicle from stalling and achieving fault protection.

[0058] In this embodiment, a third tension spring 17 is provided between the clutch stop block 12 and the mounting plate 2. One end of the third tension spring 17 is connected to the mounting plate 2, and the other end of the third tension spring 17 is connected to the top of the clutch stop block 12. If the clutch stop block 12 fails to lift due to an unexpected malfunction, the third tension spring 17 will cause the safety pin 11 to break as the force on the clutch stop block 12 increases. This will lift the clutch stop block 12 under the action of the third tension spring 17, releasing it from contact with the pin connecting rod 26, preventing damage to the lubrication mechanism and the mold base transmission part, and achieving overload safety protection.

[0059] The top end of the refueling pipe 8 is hinged to the lifting top plate 7. An elastic reset component is also provided between the refueling pipe 8 and the lifting top plate 7. Under the action of the elastic reset component, the refueling pipe 8 is set vertically.

[0060] In this embodiment, the side of the refueling pipe 8 closest to the direction of movement of the transmission chain 25 is hinged to the lifting top plate 7 using a hinge shaft. The elastic reset component is a fourth tension spring 18 located between the refueling pipe 8 and the lifting top plate 7. One end of the fourth tension spring 18 is connected to the lifting top plate 7, and the other end of the fourth tension spring 18 is connected to the other side of the top of the refueling pipe 8. The fourth tension spring 18 is in a stretched state.

[0061] The refueling pipe 8 is hinged to the lifting top plate 7 and vertically set using an elastic reset component, so that the refueling pipe 8 can rotate and swing along the movement direction of the transmission chain 25. If the pin 27 to be refueled has a damaged bent arm or other protruding structure, the refueling pipe 8 can automatically avoid it by rotating and swinging after contact and being subjected to force, thereby avoiding damage to the refueling pipe 8. After avoiding the force, the refueling pipe 8 can automatically reset to a vertical state for normal refueling of the next batch of pins 27.

[0062] In this embodiment, the synchronous transmission mechanism includes a plurality of synchronous pulleys 19 rotatably mounted on the frame 1, a synchronous belt 20 is wound around the plurality of synchronous pulleys 19, and two mounting plates 2 are respectively fixedly connected to both sides of the synchronous belt 20.

[0063] In this embodiment, there are four synchronous pulleys 19, which are respectively arranged in pairs at both ends of the frame 1. Of course, a tensioning pulley for tensioning the synchronous belt 20 can also be rotatably installed on the frame 1.

[0064] The synchronous transmission mechanism is provided, and the synchronous belt 20 can rotate. The mounting plates 2 of the two sets of refueling mechanisms are fixedly connected to both sides of the synchronous belt 20, so that one set of refueling mechanisms can drive the other set of refueling mechanisms to slide in the opposite direction, thereby realizing the reciprocating cyclic displacement of the two sets of refueling mechanisms.

[0065] Of course, the synchronous transmission mechanism is not limited to the above-described implementation in this embodiment. For example, the synchronous transmission mechanism may be selected from several synchronous sprockets rotatably mounted on the frame 1 and a synchronous chain wrapped between each synchronous sprocket, or it may be selected from several I-beams rotatably mounted on the frame 1 and a wire rope wrapped between each I-beam.

[0066] In this embodiment, a sensor mounting plate 21 is provided on the frame 1, and a detection sensor 22 for detecting the pin connecting rod 26 is installed on the sensor mounting plate 21. The detection sensor 22 can detect the pin connecting rod 26 during the movement and feed the detection signal back to the control system. This ensures that when the control system controls the clutch assembly of the refueling mechanism to be connected to the transmission chain 25, the clutch stop 12 can always be inserted between the two pin connecting rods 26, and there will be no collision between the clutch stop 12 and the pin connecting rod 26 when it is inserted, which would cause a malfunction. This ensures the operational safety of the refueling device.

[0067] In this embodiment, two detection sensors 22 are provided. The two detection sensors 22 are used to detect the pin connecting rods 26 on both sides of the transmission chain 25, so that if one detection sensor 22 fails, the other detection sensor 22 can still detect the pin connecting rods 26.

[0068] In this embodiment, the two ends of the frame 1 are respectively equipped with second hydraulic buffers 24 by the second mounting blocks 23, and the second hydraulic buffers 24 are respectively set with the mounting plate 2. When the installed second hydraulic buffers 24 complete a fixed-point refueling operation, the second hydraulic buffers 24 can buffer the force when the two refueling mechanisms collide, thereby achieving smooth stopping of the two refueling mechanisms when they move to the end of their stroke.

[0069] In this embodiment, to facilitate the description of the working principle of the non-powered synchronous fixed-point refueling device, one set of refueling mechanisms used to refuel the pin 27 on one side of the transmission chain 25 is defined as the left refueling mechanism, and the other set of refueling mechanisms used to refuel the pin 27 on the other side of the transmission chain 25 is defined as the right refueling mechanism.

[0070] Based on the above structure, this non-powered synchronous fixed-point refueling device has a simple and compact structure. During operation, when the detection sensor 22 detects the pin connecting rod 26, the control system controls the clutch assembly of the left refueling mechanism to engage and the refueling pipe 8 to move downward according to the set program. The left refueling mechanism maintains a linked state with the transmission chain 25 and moves synchronously forward with the transmission chain 25. The right refueling mechanism moves in the opposite direction to the transmission chain 25 under the drive of the synchronous transmission mechanism. At this time, the left refueling mechanism begins to refuel the pin 27 on the left side of the transmission chain 25. After the refueling mechanism finishes moving... Before refueling, the system stops; after the movement ends, the control system controls the clutch assembly of the left refueling mechanism to disengage, the refueling pipe 8 to rise and reset, the clutch assembly of the right refueling mechanism to engage, the refueling pipe 8 to move downward, the right refueling mechanism to maintain linkage with the transmission chain 25 and move synchronously forward with the transmission chain 25, the left refueling mechanism to move in the opposite direction with the transmission chain 25 under the drive of the synchronous transmission mechanism, at this time the right refueling mechanism begins to refuel the pin 27 on the right side of the transmission chain 25; this cycle repeats, thereby realizing the fixed-point refueling of the pins 27 on both sides of the transmission chain 25.

[0071] This non-powered synchronous fixed-point lubrication device can accurately add lubricating oil to the pins on both sides of the transmission chain without the need for an additional power unit. This not only ensures accurate, uniform, and efficient lubrication, but also reduces operating costs and prevents missed or repeated additions, thus avoiding contamination of the mold base and idle areas and saving lubricating oil. It is highly practical.

[0072] Example 2

[0073] This embodiment has the same structure as Embodiment 1, except that the elastic reset component is a torsion spring, the top end of the refueling pipe 8 is hinged to the lifting top plate 7 using a hinge shaft, and under the action of the torsion spring, the refueling pipe 8 is vertically set and can rotate and swing along the movement direction of the transmission chain 25.

[0074] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the invention. Furthermore, it should be understood that after reading the technical description of this invention, those skilled in the art can make various alterations, modifications, and / or variations to the invention, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
