Description

Technical Field

[0001] This invention relates to a lubrication device for spinning components, and more particularly to an automatic lubrication device for rubber rollers. Background Technology

[0002] The spinning machine's drafting mechanism consists of a roller that holds the yarn and performs drafting. The jaws formed by the roller and the lower roller firmly hold the yarn. Through precise control, the fiber can be stably speed-changed within the drafting zone, thereby drawing a finer yarn.

[0003] A roller typically consists of an internal metal core, rolling bearings, and an outer elastic covering. This allows the roller to create an effective frictional field through elastic deformation when in contact with the lower roller, thus stably controlling fiber movement. The roller is mounted on the roller seat via bearings and rotates at high speed under transmission. Good lubrication significantly reduces the coefficient of friction within the bearings, minimizing wear and extending the service life of the roller and its bearings. Without lubrication, the bearings may become sluggish due to dry friction, even jamming or jerking, resulting in uneven yarn and regular thick and thin spots, severely impacting yarn quality. For these reasons, rollers need to be disassembled and greased after a period of use. However, in current technology, grease is added manually by placing the roller on a fixed seat, resulting in low efficiency and operator fatigue from repetitive labor.

[0004] Therefore, those skilled in the art are dedicated to developing an automatic grease-adding device for rubber rollers, which facilitates the rapid and automatic application of grease to both ends of the rubber rollers, thereby reducing the labor intensity of operators. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an automatic oiling device for rubber rollers, which facilitates the rapid and automatic application of grease to both ends of the rubber rollers, thereby reducing the labor intensity of operators.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: An automatic oiling device for rubber rollers, comprising: A feed conveyor track, which is mounted on the frame and used to convey the rubber rollers; A positioning seat is located at the output end of the feeding conveyor track, and a flipping component is installed on the positioning seat; A clamping and oiling assembly, two of which are located on both sides of the positioning seat and are used to apply oil to the roller on the positioning seat; The discharge conveyor track, with its input end located on the side wall of the positioning seat, is used to convey the filled roller backward. A control component, which is electrically connected to the flipping component and the clamping refueling component.

[0007] The beneficial effects of adopting the above scheme are: the roller enters the feeding conveyor track and is conveyed to the positioning seat in sequence. After the clamping and greasing component adds grease to both ends of the roller, the flipping component drives the positioning seat to flip so that the roller enters the discharge conveyor track. Through the coordinated work of various components, the entire process of feeding, positioning, simultaneous lubrication at both ends, and unloading of the rollers can be completed without manual intervention, greatly improving lubrication efficiency and significantly reducing the labor intensity of operators.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the positioning seat includes a first fixing member and a second fixing member, the ends of the first fixing member and the second fixing member are vertically connected, one end of the connection between the first fixing member and the second fixing member is connected to a rotating shaft, and the other end is connected to the flipping assembly.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the ends of the first fixing member and the second fixing member are vertically connected, and a rotating shaft and a flipping component are set at the connection, so that the positioning seat can not only reliably support and position the roller, providing a stable working platform for clamping the oiling component, but also achieve a smooth flipping action after oiling is completed, making it easy to unload the roller onto the discharge conveyor track.

[0011] Furthermore, the flipping assembly includes a flipping cylinder, the output end of which is connected to a flipping rack, the flipping rack being meshed with a flipping gear, the flipping gear being connected to the end of the positioning seat, and the extension and retraction of the flipping cylinder causing the positioning seat to flip, thereby conveying the single roller that has been lubricated to the discharge conveying track.

[0012] The beneficial effects of adopting the above-mentioned further solution are: the tilting cylinder converts linear motion into rotational motion through the rack and pinion mechanism, thereby driving the positioning seat to tilt stably, ensuring that the oiled roller can be accurately and reliably transferred to the discharge conveyor track, avoiding jamming or positional deviation, and ensuring the smoothness of the automated process.

[0013] Furthermore, a limiting plate is provided at the lower end of the first fixing member, a guide telescopic shaft is connected to the lower end of the limiting plate, a telescopic sleeve is connected to the telescopic shaft, a base is connected to the lower end of the telescopic sleeve, and a return spring is provided on the telescopic shaft and the telescopic sleeve. When the first fixing member is reset to the horizontal position, it abuts against the limiting plate, causing the single roller to roll onto the positioning seat.

[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: through the cooperation of the limiting plate, guide telescopic shaft, telescopic sleeve and return spring, when the first fixed part is reset to the horizontal position, it can accurately and stably stop at the predetermined position, preparing for receiving the next roller. It can effectively buffer and absorb the impact when the positioning seat flips and resets, improve the service life of the equipment, and at the same time ensure the consistency of the reset position each time, thereby ensuring that the roller can accurately roll to the designated position on the positioning seat, improving the positioning accuracy and the operational reliability of the entire system.

[0015] Furthermore, the clamping refueling assembly includes a pneumatic refueling device, with two pneumatic refueling devices arranged opposite each other, and the pneumatic refueling devices connected to the refueling device via hoses; The pneumatic fuel dispenser is mounted on a push cylinder, and the push cylinder is mounted on an adjustment assembly.

[0016] The beneficial effects of adopting the above-mentioned further solution are: the two pneumatic oilers arranged opposite each other can simultaneously and accurately lubricate the bearings at both ends of the roller, which is highly efficient and avoids omissions or unevenness that may occur with manual operation, thereby improving the lubrication efficiency.

[0017] Furthermore, the adjustment assembly includes sliding rods, two of which are arranged in parallel, and a fixed base is connected to the end of each sliding rod; The push cylinder is mounted on the sliding rod, and an adjusting screw is provided between the fixed base and the end of the push cylinder.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the sliding rod and the fixed seat form a stable sliding pair, ensuring that the push cylinder and the pneumatic refueling device can move smoothly along a straight line; The adjusting screw allows for precise adjustment of the relative distance between the two clamping and oiling components, enabling the automatic oiling device to adapt to rollers of different lengths, greatly improving the versatility and flexibility of the equipment. Furthermore, the control components include a PLC controller and a human-machine interface, with the PLC controller electrically connected to both the flipping component and the clamping and oiling component.

[0019] The beneficial effect of adopting the above-mentioned further solution is that by using a PLC controller as the control unit, the timing of the actions of the flipping component and the clamping and refueling component can be precisely coordinated, ensuring that the entire automated process operates efficiently and without errors.

[0020] Furthermore, the pneumatic refueling device is equipped with a metering valve, which is electrically connected to the control component.

[0021] The beneficial effect of adopting the above-mentioned further solution is that the metering valve can accurately control the amount of oil injected each time, thus achieving metered refueling. Attached Figure Description

Detailed Implementation

[0024] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0025] In the description of this invention, it should be understood that the terms "center," "length," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "inner," "outer," "circumferential," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the system or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0026] In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0027] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, an automatic oiling device for rubber rollers includes a feeding conveyor track 1, which is installed on a frame 2 and used to convey rubber rollers. It achieves power transmission through a conveyor roller or conveyor belt structure set along the length of the track, which can smoothly convey the rubber roller to be oiled along a preset path, ensuring that the rubber roller does not deviate or get stuck during the conveying process, and finally accurately conveys it to the subsequent positioning structure.

[0029] Positioning seat 3 is located at the output end of the feeding conveyor track 1 and is used to receive a single roller conveyed from the feeding conveyor track 1, providing stable positioning support for the roller lubrication operation. A flipping component 4 is installed on the positioning seat 3, which can drive the positioning seat 3 to rotate around a specific axis, so as to realize the transfer of the roller after the lubrication is completed.

[0030] The two clamping oiling components 5 are located on both sides of the positioning seat 3 and are used to apply grease to the roller on the positioning seat 3. The two clamping oiling components 5 can approach the roller from both ends simultaneously and apply grease to the bearing part of the roller to ensure the uniformity and completeness of the oiling and avoid the problems of missing or insufficient oiling that occur when manually oiling.

[0031] The discharge conveyor track 6 has its input end located on the side wall of the positioning seat 3 for conveying the filled roller backward. Its conveying direction is consistent with that of the feeding conveyor track 1. After the positioning seat 3 is flipped under the drive of the flipping component 4, the roller can roll smoothly onto the discharge conveyor track 6 by its own gravity. Then, the discharge conveyor track 6 conveys the filled roller backward to the next process.

[0032] The control component 7 is electrically connected to the flipping component 4 and the clamping and refueling component 5. It can receive position signals and status signals from each component and send action commands to the flipping component 4 and the clamping and refueling component 5 according to a preset program to achieve precise coordination of the actions of each component.

[0033] like Figure 1 , Figure 2 As shown in the embodiment, the positioning seat 3 includes a first fixing member 8 and a second fixing member 9. The ends of the first fixing member 8 and the second fixing member 9 are vertically connected to form an L-shaped support structure. One end of the connection between the first fixing member 8 and the second fixing member 9 is connected to a rotating shaft, which provides a rotation center for the rotation of the positioning seat 3, ensuring the stability and accuracy of the rotation action. The other end is connected to a rotation component 4. The driving force generated by the rotation component 4 is transmitted to the entire positioning seat 3 through the connection, causing the positioning seat 3 to rotate 90° around the rotating shaft.

[0034] like Figure 1 , Figure 2As shown, in another embodiment, the flipping assembly 4 includes a flipping cylinder 10, the output end of which is connected to a flipping rack 11. When compressed air is introduced into the flipping cylinder 10, its piston rod will move linearly along the axial direction, thereby driving the flipping rack 11 connected thereto to move linearly in sync. The flipping rack 11 is meshed with a flipping gear 12. The linear motion of the flipping rack 11 is converted into the rotational motion of the flipping gear 12 through gear and rack meshing transmission. The flipping gear 12 is connected to the end of the positioning seat 3. The rotation of the flipping gear 12 will directly drive the positioning seat 3 to rotate around the rotating shaft. The extension and retraction of the flipping cylinder 10 causes the positioning seat 3 to flip, thereby conveying the single roller that has been lubricated to the discharge conveying track 6, realizing the automatic transfer of the roller.

[0035] The lower end of the first fixing member 8 is also provided with a limiting plate 13. The limiting plate 13 is used to limit the roller on the feeding conveyor track 1 when the flipping assembly 4 drives the positioning seat 3 to flip. The lower end of the limiting plate 13 is connected to a guide telescopic shaft, and the telescopic shaft is connected to a telescopic sleeve. The lower end of the telescopic sleeve is connected to a base 14. The telescopic shaft can slide back and forth along the axial direction in the telescopic sleeve to provide guidance for the up and down movement of the limiting plate 13. The telescopic shaft and the telescopic sleeve are fitted with a return spring 15. When the first fixing member 8 is reset to the horizontal position, it abuts against the limiting plate 13 so that the single roller rolls onto the positioning seat 3.

[0036] Specifically, when the flipping assembly 4 drives the positioning seat 3 to rotate, causing the first fixing member 8 to return to the horizontal position, the first fixing member 8 abuts against the compression limiting plate 13, causing the roller on the feeding conveying track 1 to roll onto the positioning seat 3 under gravity, for subsequent clamping and grease application. After the roller on the positioning seat 3 has finished applying grease, the flipping assembly 4 drives the positioning seat 3 to rotate, causing the first fixing member 8 to gradually become vertical. During the rotation, the limiting plate 13 extends synchronously with the first fixing member 8 under the spring force of the return spring 15, thereby blocking the roller on the feeding conveying track 1 and preventing the feeding conveying track 1 from sliding when the positioning seat 3 flips. When the flipping assembly 4 drives the positioning seat 3 to rotate, causing the first fixing member 8 to return to the horizontal position again, the above actions are repeated without manual operation.

[0037] The telescopic shaft, telescopic sleeve, and return spring 15 not only limit the roller but also provide cushioning when the positioning seat 3 rotates to the horizontal position. They also limit the horizontal position of the first fixing member 8. Simultaneously, a limiting post and a shock-absorbing spring are installed on the side wall of the second fixing member 9. When the second fixing member 9 rotates to the horizontal position, the shock-absorbing spring dampens vibration, and the limiting post limits the movement, allowing the positioning seat 3 to roll directly onto the discharge conveyor track 6 under gravity. The telescopic shaft, telescopic sleeve, and limiting post ensure that the positioning seat 3 reaches the designated position during rotation.

[0038] like Figure 1 , Figure 2As shown, in one embodiment, the clamping and refueling assembly 5 includes a pneumatic refueling device 16, on which a metering valve is installed. The metering valve is electrically connected to the control assembly 7. The control assembly 7 can send a control signal to the metering valve according to the preset refueling quantity parameters. The metering valve can precisely control the output quantity of grease each time by adjusting the opening degree and opening time of the internal valve core, ensuring that the refueling quantity is consistent each time, and avoiding grease waste or insufficient refueling that would affect the performance of the roller. Two pneumatic oilers 16 are arranged opposite each other, enabling simultaneous oiling from both ends of the roller, significantly improving oiling efficiency. The pneumatic oilers 16 are connected to the oil supply unit 17 via hoses. The grease stored in the oil supply unit 17 continuously supplies oil to the pneumatic oilers 16 through the hoses, ensuring the continuity of the oiling operation. The pneumatic oilers 16 are mounted on a push cylinder 18, which drives the pneumatic oilers 16 to move towards or away from the roller, achieving precise docking and separation between the oilers and the roller. The push cylinder 18 is mounted on an adjustment assembly, which is used to adjust the positions of the push cylinder 18 and the pneumatic oilers 16.

[0039] The adjustment assembly includes two sliding rods 19 arranged in parallel to form a stable sliding support structure. A fixed seat 20 is connected to the end of each sliding rod 19, providing fixed support and ensuring the stability of the sliding rod 19's position. A push cylinder 18 is mounted on the sliding rod 19 and can slide along the axis of the sliding rod 19 to achieve lateral position adjustment. An adjusting screw 21 is provided between the fixed seat 20 and the end of the push cylinder 18. Rotating the adjusting screw 21 pushes or pulls the push cylinder 18 along the sliding rod 19. By precisely rotating the adjusting screw 21, the distance between the two pneumatic oilers 16 can be precisely controlled, thus adapting to rollers of different lengths and improving the device's versatility.

[0040] In this embodiment, the control component 7 includes a PLC controller and a human-machine interface. The PLC controller serves as the core of the entire device's control, pre-stored with a complete control program for roller lubrication. It can receive position detection signals from the positioning seat 3, status signals from the pneumatic lubricator 16, etc. After logical operations, it sends extension and retraction commands to the tilting cylinder 10 of the tilting component 4, and sends action commands to the pushing cylinder 18, pneumatic lubricator 16, and metering valve of the clamping lubrication component 5. This achieves precise timing control of the movements of the tilting component 4 and the clamping lubrication component 5, ensuring orderly connection of each link. The human-machine interface uses a touch screen or button panel. Operators can use this interface to set parameters such as lubrication volume, conveying speed, and tilting angle, and can also view the device's operating status and fault information in real time, facilitating parameter adjustment and equipment maintenance.
