Description

Technical Field

[0001] This invention relates to the field of coupling technology, specifically to a coupling for a production equipment for toiletries and its usage. Background Technology

[0002] A coupling is a device that connects two shafts or a shaft and a rotating component, allowing them to rotate together during motion and power transmission, and remaining connected under normal conditions. Sometimes it is also used as a safety device to prevent the connected components from bearing excessive loads, thus providing overload protection.

[0003] Existing couplings used in personal care product manufacturing equipment are typically rigid couplings and flexible couplings. Rigid couplings (such as sleeve type and flange type) have extremely high requirements for the coaxiality of the two shafts. If there is even a slight deviation during installation (axial, radial, or angular offset), it will lead to increased equipment vibration and noise, and may even cause premature wear of bearings or gears. While flexible couplings can absorb some deviations, after long-term cyclic loads, the elastic elements are prone to fatigue and aging, resulting in a decrease in compensation capacity. This can cause shaft displacement in mixing tanks, mixers, etc., in personal care equipment due to temperature changes or load fluctuations. If the coupling cannot adapt, it will lead to transmission failure. Therefore, we provide a coupling for personal care product manufacturing equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a coupling for production equipment of personal care products, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A coupling for a washing and care product manufacturing equipment includes a drive shaft and a driven shaft. A drive disc is fixedly installed at one end of the drive shaft near the driven shaft, and a driven disc is fixedly installed at one end of the driven shaft near the drive disc. Drive blocks are arranged in an array at one end of the drive disc near the driven disc, and driven blocks are arranged in an array at one side end of the driven disc near the drive blocks. A transmission mechanism is provided between the drive blocks and the driven blocks to enable meshing and transmission and to automatically calibrate the vibration and offset generated during the transmission process. An adjustment mechanism is provided at one end of the driven disc near the transmission mechanism to calibrate and adjust the force intensity of the transmission mechanism.

[0007] The transmission mechanism includes a transmission sleeve, which is disposed between the driving block and the driven block. A contact plate is fixedly installed on the protruding inner wall of the transmission sleeve, and an arc block is fixedly installed on the arc inner wall of the transmission sleeve. An arc groove is formed on the arc surface of the inner wall of the arc block. An arc strip is slidably disposed in the arc groove, and the arc strip and the arc groove are slidably connected in sequence to form a ring. All the arc blocks are disposed at the protruding end of the transmission sleeve.

[0008] The outer arc surface of the arc block is provided with a sliding groove. A slider is slidably installed on the inner wall of the sliding groove near the contact plate. A rotating rod is fixedly installed on the upper end of the slider. A connecting seat is fixedly installed on the contact plate near the lower end of the rotating rod, and the rotating rod is rotatably installed on the lower end of the connecting seat.

[0009] Preferably, a connecting cylinder is fixedly installed on the inner wall of the transmission sleeve, and the arc strip is fixedly sleeved on the outer wall of the connecting cylinder. Water pipes are arrayed on the outer wall of the connecting cylinder near the contact plate. An expansion block is fixedly connected to the end of each water pipe away from the connecting cylinder, and the expansion blocks are fixedly installed between the contact plates.

[0010] Preferably, a connecting pipe is fixedly installed at the input end of the connecting cylinder, and a control cylinder is fixedly connected at the end of the connecting pipe away from the connecting cylinder. The control cylinder is fixedly installed on the inner wall of the driven plate.

[0011] Preferably, the adjustment mechanism includes a control ring, which is fixedly sleeved on the outer wall of the driven disc near the driven block. Multiple threaded bolts are arrayed on the outer wall of the control ring, and all the threaded bolts are rotatably mounted on the outer wall of the control ring.

[0012] Preferably, a threaded cylinder is threadedly installed at the lower end of the control ring, and an arc plate is fixedly installed at the lower end of the threaded cylinder, with the arc plate abutting against the outer surface of the control cylinder.

[0013] The upper end of the threaded cylinder is provided with multiple mounting holes, in which limit rods are slidably installed, and the end of the limit rod away from the threaded cylinder is fixedly installed on the inner wall of the control ring.

[0014] This invention also discloses a method for using a coupling in a personal care product manufacturing equipment, the method comprising the following steps:

[0015] S1: First, install the power rod and the force rod that needs to be rotated in the washing and care product production equipment at one end of the drive shaft and the driven shaft, respectively;

[0016] S2: Secondly, when the drive shaft rotates, the drive disc causes the drive block to push the driven block to start rotating through the transmission mechanism, thus causing the driven shaft to start rotating;

[0017] S3: Again, by using the adjusting mechanism to adjust the internal pressure of the transmission mechanism to a suitable level, the coupling can be adapted to various environments and mechanical transmission positions with different transmission forces.

[0018] S4: Through the cooperation of the transmission mechanism and the adjustment mechanism, the hydraulic transmission component of the coupling hydraulically transmits the offset, vibration and tilt caused by the coupling to the other side without squeezing the transmission component during the transmission process. This avoids the problem of fatigue aging and reduced compensation capability of the transmission component during long-term transmission.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This invention replaces the flexible elastic component in the original device with a hydraulically controlled elastic component, so that during the transmission process, the hydraulic transmission component hydraulically transmits the offset, vibration and tilt caused by the coupling to the other side without squeezing the transmission component. This avoids the problem of fatigue aging and reduced compensation capability of the transmission component during long-term transmission.

[0021] 2. The present invention also enables the hydraulic transmission component to transmit hydraulic pressure to the other side of the transmission component without squeezing it during the vibration and offset process, so that the transmission component can still fit between the driving plate and the driven plate, thereby reducing the wear of the transmission component and increasing its transmission capacity.

[0022] 3. When inspecting and maintaining the transmission mechanism, the present invention uses a control mechanism to quickly adjust the transmission mechanism to a suitable transmission intensity, so that the staff does not need to replace the transmission components, making maintenance more convenient.

[0023] 4. The coupling of the present invention can be applied to various environments and mechanical transmission positions with different transmission forces, thereby increasing the scope and applicability of the coupling. Attached Figure Description

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] This invention provides a technical solution: such as Figure 1 - Figure 8As shown, a coupling for a personal care product manufacturing equipment includes a drive shaft 1 and a driven shaft 2. Both drive shaft 1 and driven shaft 2 are power rods requiring transmission and force rods requiring rotation in the personal care product manufacturing equipment. A drive disc 3 is fixedly installed at one end of drive shaft 1 near driven shaft 2, and a driven disc 4 is fixedly installed at one end of driven shaft 2 near drive disc 3. Drive blocks 5 are arranged in an array at one end of drive disc 3 near driven disc 4, and driven blocks 6 are arranged in an array at the side end of driven disc 4 near drive blocks 5. A transmission mechanism is provided between drive blocks 5 and driven blocks 6 to enable meshing and transmission, and to automatically calibrate vibrations and offsets generated during transmission. An adjustment mechanism is provided at the end of driven disc 4 near the transmission mechanism to calibrate and adjust the force intensity of the transmission mechanism. When the coupling experiences offset or abnormal data transmission, the adjustment mechanism controls the transmission mechanism to ensure the transmission... The structure can quickly restore to a suitable transmission strength, making maintenance more convenient for staff. Simultaneously, the transmission range and force of the coupling can be controlled to a suitable level through the adjustment mechanism. This allows the coupling of the present invention to be applicable to various environments and mechanical transmission positions with different transmission forces, increasing the coupling's applicability and practicality. Specifically, the transmission mechanism replaces the original flexible elastic component with a hydraulically controlled elastic component. During transmission, the hydraulic transmission component hydraulically transmits the offset, vibration, and tilt caused by the coupling to the other side without compressing the transmission component. This prevents fatigue aging and decreased compensation capacity of the transmission component during long-term transmission.

[0035] The transmission mechanism includes a transmission sleeve 7, which is gear-shaped, but the protruding part of the transmission sleeve 7 is designed to be arc-shaped to fit the gap between the driving block 5 and the driven block 6. The transmission sleeve 7 is positioned between the driving block 5 and the driven block 6, allowing the driving block 5 and the driven block 6 to mesh and transmit power through the transmission sleeve 7. A contact plate 14 is fixedly installed on the protruding inner wall of the transmission sleeve 7, and an arc block 15 is fixedly installed on the arc-shaped inner wall of the transmission sleeve 7. An arc groove 18 is formed on the arc surface of the inner wall of the arc block 15, and an arc strip 17 is slidably disposed in the arc groove 18. The arc strip 17 and the arc... The grooves 18 are all made of elastic steel, which is not described in detail here. The arc strip 17 and the arc groove 18 are slidably connected to form a ring. The arc blocks 15 are all set at the protruding end of the transmission sleeve 7. When the drive shaft 1 and the driven shaft 2 vibrate or deviate, the arc block 15 and the arc strip 17 are squeezed. The arc strip 17 retracts into the arc groove 18 opened by the arc block 15. When the deviation range is too large, the arc block 15 and the arc strip 17 bend so that the transmission sleeve 7 is still attached between the drive block 5 and the driven block 6, so that the transmission output efficiency can still be kept within a suitable range.

[0036] The outer arc surface of the arc block 15 is provided with a sliding groove 19. A slider 20 is slidably installed on the inner wall of the sliding groove 19 near the contact plate 14. A rotating rod 21 is fixedly installed on the upper end of the slider 20. A connecting seat 22 is fixedly installed on the lower end of the contact plate 14 near the rotating rod 21. The rotating rod 21 is rotatably installed on the lower end of the connecting seat 22. When the distance between the contact plate 14 at the relative moving position of the drive shaft 1 and the driven shaft 2 decreases, the drive block 5 and the driven block 6 squeeze and push the contact plate 14. The contact plate 14 moves while rotating, so that the contact plate 14 can remain in contact with the gap between the drive block 5 and the driven block 6 and parallel to the side of the gap between the drive block 5 and the driven block 6.

[0037] A connecting cylinder 12 is fixedly installed on the inner wall of the transmission sleeve 7, and an arc strip 17 is fixedly sleeved on the outer wall of the connecting cylinder 12. Water pipes 16 are arrayed on the outer wall of the connecting cylinder 12 near the contact plate 14. An expansion block 13 is fixedly connected to the end of the water pipe 16 away from the connecting cylinder 12, and the expansion blocks 13 are fixedly installed between the contact plates 14. When there is a misalignment or angle between the drive shaft 1 and the driven shaft 2, the gap between the relative misalignment and folding angle position of the drive block 5 and the driven block 6 decreases, causing the distance between the contact plates 14 to begin to decrease. The contact plates 14 squeeze the expansion blocks 13, thereby playing the role of shock absorption and transmission.

[0038] A connecting pipe 10 is fixedly installed at the input end of the connecting cylinder 12. A control cylinder 11 is fixedly connected to the end of the connecting pipe 10 away from the connecting cylinder 12. The control cylinder 11 is fixedly installed on the inner wall of the driven plate 4. The hydraulic pressure in the control cylinder 11 is transmitted to the connecting cylinder 12 through the connecting pipe 10, so that the hydraulic pressure in both the connecting cylinder 12 and the expansion block 13 can be controlled through the connecting cylinder 12, making it more convenient to control the hydraulic pressure of the connecting cylinder 12 through the control cylinder 11.

[0039] The adjustment mechanism includes a control ring 8, which is fixedly sleeved on the outer wall of the driven disc 4 near the driven block 6. Multiple threaded bolts 9 are arrayed on the outer wall of the control ring 8, and all threaded bolts 9 are rotatably mounted on the outer wall of the control ring 8. A threaded cylinder 24 is threadedly installed at the lower end of the control ring 8, and an arc plate 23 is fixedly installed at the lower end of the threaded cylinder 24. The arc plate 23 is arc-shaped, and the inner arc of the arc plate 23 matches the outer diameter of the control cylinder 11. The arc plate 23 abuts against the outer surface of the control cylinder 11. When it is necessary to adjust the force between the transmission sleeve 7 and the driving block 5 and the transmission sleeve 7, the corresponding threaded bolts 9 are rotated, causing the threaded cylinder 24 to move and squeeze the control cylinder 11, squeezing the control cylinder 11 into an elliptical shape. The liquid in the control cylinder 11 is transferred to the connecting cylinder 12 through the connecting pipe 10, and then evenly transferred to the expansion block 13 through the water pipe 16, so that the contact plate 14 abuts against the gap between the driving block 5 and the driven block 6, increasing the force.

[0040] The upper end of the threaded cylinder 24 is provided with multiple mounting holes, in which limit rods 25 are slidably installed. The end of the limit rod 25 away from the threaded cylinder 24 is fixedly installed on the inner wall of the control ring 8. Specifically, when the threaded bolt 9 is rotated, the limit rod 25 causes the threaded cylinder 24 at the lower end of the threaded bolt 9 to start moving up and down, so as to prevent the threaded cylinder 24 from rotating with the threaded bolt 9 when the threaded bolt 9 is rotated, thus playing a guiding role.

[0041] It should be noted that the material used for the transmission sleeve 7 is the elastic rubber material in the prior art. The outer surface of the transmission sleeve 7 is set to a smooth outer surface to reduce the friction between the driving block 5, the driven block 6 and the transmission sleeve 7, thereby extending the service life of the transmission sleeve 7.

[0042] It should be noted that the control cylinder 11 and connecting cylinder 12 mentioned in the text are both made of high-strength elastic materials in the prior art, which allows the control cylinder 11 and connecting cylinder 12 to deform only slightly. At the same time, the slight deformation has negligible impact on the strength fatigue of the control cylinder 11 and connecting cylinder 12. When the arc plate 23 compresses the control cylinder 11, the control cylinder 11 begins to deform, but the shape of the deformation is controlled by multiple threaded bolts 9. When the control cylinder 11 becomes elliptical, the internal space of the control cylinder 11 begins to decrease, allowing the hydraulic pressure in the control cylinder 11 to be transmitted to the connecting cylinder 12. The connecting pipe 10 that connects the control cylinder 11 and the connecting cylinder 12 is a non-deformable steel pipe.

[0043] It should be noted that when there is a misalignment or angular deviation in the connection between the driving block 5 and the driven block 6, the distance between the contact plates 14 at the relative moving positions of the driving shaft 1 and the driven shaft 2 decreases, while the distance between the contact plates 14 in the opposite direction increases. The decrease in the distance between the contact plates 14 will squeeze the expansion block 13, and the liquid inside the squeezed expansion block 13 will be transported to the expansion block 13 with the increased distance between the contact plates 14, so that the contact plates 14 are still attached between the driving block 5 and the driven block 6, making its conveying efficiency higher.

[0044] It should be noted that the proportions of the device parts in the picture differ from those of the machine parts, and the image structure is only for reference regarding the operating principle of the structure.

[0045] Working principle: When the coupling is installed and put into use, the drive shaft 1 causes the drive disc 3 to rotate, which in turn drives the drive block 5 to rotate. The drive block 5 presses against and pushes the transmission sleeve 7, causing the transmission sleeve 7 to push the driven block 6 to rotate, which in turn drives the driven disc 4 to rotate, and the driven shaft 2 to rotate. During the transmission process, when there is a relative offset or angle between the drive shaft 1 and the driven shaft 2, the gap between the drive block 5 and the driven block 6 decreases. The drive block 5 and the driven block 6 press against the transmission sleeve 7, and the contact plates 14 inside the transmission sleeve 7 move closer to each other, pressing against the expansion block 13. The liquid in the expansion block 13 is transferred to the connecting cylinder 12 through the water pipe 16. At the same time, the drive block 5 and the driven block 6... As the gap between the relatively opposite moving positions begins to increase, the liquid in the connecting cylinder 12 is transferred through the water pipe 16 to the relatively opposite moving expansion block 13, causing the expansion block 13 to expand and push the contact plate 14. The contact plate 14, which moves in the opposite direction, pushes the transmission sleeve 7 to press against the gap between the expanding active block 5 and the driven block 6, thus completing the complementarity. During the transmission process, the hydraulic transmission component of the coupling hydraulically transmits the offset, vibration, and tilt generated by the coupling to the other side that does not press the transmission component. This prevents the transmission component from easily fatigued and aged, and the compensation capability from decreasing, during long-term transmission.

[0046] This invention also discloses a method for using a coupling in a personal care product manufacturing equipment, the method comprising the following steps:

[0047] S1: First, install the power rod and the force rod that needs to be rotated in the washing and care product production equipment at one end of the drive shaft 1 and the driven shaft 2 respectively;

[0048] S2: Secondly, when the drive shaft 1 rotates, the drive disk 3 causes the drive block 5 to drive the driven block 6 to start rotating through the transmission mechanism, so that the driven shaft 2 starts to rotate.

[0049] S3: Again, by using the adjusting mechanism to adjust the internal pressure of the transmission mechanism to a suitable level, the coupling can be adapted to various environments and mechanical transmission positions with different transmission forces.

[0050] S4: Through the cooperation of the transmission mechanism and the adjustment mechanism, the hydraulic transmission component of the coupling hydraulically transmits the offset, vibration and tilt caused by the coupling to the other side without squeezing the transmission component during the transmission process. This avoids the problem of fatigue aging and reduced compensation capability of the transmission component during long-term transmission.
