Description

Technical Field

[0001] The present invention belongs to the technical field of winding mechanisms, and in particular relates to a double-axis friction winding support flexible mechanism and a use method thereof. Background Art

[0002] When friction-winding microfiber leather, product performance requirements necessitate the use of a low-tension, dual-axis friction winder. The support and clamping mechanism is placed between the two friction rollers and continuously raises as the roll diameter increases. After winding is complete, the support and clamping mechanism releases the roll. Unsupported, the support and clamping mechanism experiences free fall under gravity. To prevent damage, cushioning pads are typically placed beneath the support and clamping mechanism, or a long pneumatic cylinder is installed on top. The cylinder length is customized based on the maximum roll radius. However, cushioning pads are not guaranteed over time, requiring frequent replacement and providing limited protection for other equipment components. Using a pneumatic cylinder to control the lowering of the support and clamping mechanism requires a large cylinder, which takes up space. In this case, if the cylinder is positioned upward, the support and clamping mechanism is affected by the unremoved gas pressure within the cylinder chamber during its ascent, which can affect the quality of the microfiber leather winding. Summary of the Invention

[0003] In order to solve the above technical problems, the technical solution adopted by the present invention is: a dual-axis friction winding support flexible mechanism, including a frame, a rack, a one-way damper, a gear, a clamping cone, a limit column, a clamping cylinder, and a linear rail. The linear rail is installed on the frame, and a slider is installed on the linear rail. The clamping cylinder is fixedly installed on the slider, and the clamping cylinder drives the clamping cone to move. The gear is rotatably installed on the slider, and the one-way damper is connected to the gear, and the gear is engaged with the rack. The rack is fixedly installed on the frame and parallel to the linear rail.

[0004] As a preferred embodiment of the above technical solution, a safety cylinder is installed at the lower end of the frame, the safety cylinder is arranged vertically upward, the piston rod of the safety cylinder is connected to a positioning rod, and a positioning portion for contacting the positioning rod is provided on the lower end of the slider or the clamping cylinder.

[0005] As a preferred embodiment of the above technical solution, the safety cylinder and the clamping cylinder are interlocked through a solenoid valve.

[0006] As a preferred embodiment of the above technical solution, the safety cylinder is connected to a timer.

[0007] As a preferred embodiment of the above technical solution, the clamping cone is connected to the piston rod of the clamping cylinder through a connecting plate, a guide rod is fixedly connected to the connecting plate, and a guide hole for the guide rod to move through is provided on the slider, and a linear bearing is installed in the guide hole.

[0008] As a preferred embodiment of the above technical solution, a limit plate is installed on the guide rod.

[0009] As a preferred embodiment of the above technical solution, the clamping cone is rotatably mounted on the connecting plate.

[0010] As a preferred embodiment of the above technical solution, the linear rail is composed of two parallel slide rails, and the two sides of the slider are respectively mounted on the two slide rails.

[0011] The method of using the double-axis friction winding support flexible mechanism is that the two ends of the cloth roll are clamped by two clamping cones respectively. As the diameter of the cloth roll continues to increase, the center position of the cloth roll continues to rise, driving the support clamping mechanism composed of the clamping cone and the clamping cylinder to gradually rise, and then driving the slider to rise on the linear rail; when the clamping cylinder drives the clamping cone to retract, the entire support clamping mechanism automatically descends, the gear rotates, and the one-way damper generates resistance, which reduces the rotation speed of the gear, thereby realizing the slow fall of the support clamping mechanism; after the support clamping mechanism descends to a certain height, it is caught by the positioning rod, and then the safety cylinder drives the positioning rod to descend, so that the support clamping mechanism is accurately reset.

[0012] The beneficial effects of the present invention are:

[0013] 1. The damper and the rack and pinion are combined to form a deceleration device. This greatly reduces the size of the positioning cylinder, while ensuring the normal operation of the support and clamping mechanism, and greatly reduces the manufacturing and maintenance costs;

[0014] 2. The cylinder is changed from being placed above to being placed below. In this way, when the supporting clamping mechanism rises, it will not be affected by the unexhausted gas pressure in the upper chamber of the cylinder, and will not affect the quality of the microfiber leather winding;

[0015] 3. The automatic slow drop of the support clamping mechanism is realized, which improves the production efficiency on site and ensures the personal safety of operators and equipment safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0021] like Figure 1-2 As shown, the dual-axis friction winding support flexible mechanism includes a frame 1, a rack 2, a one-way damper, a gear 3, a clamping cone 4, a clamping cylinder 5, and a linear rail 6. The linear rail 6 is mounted on the frame 1, and a slider 7 is mounted on the linear rail 6. The clamping cylinder 5 is fixedly mounted on the slider 7 and drives the clamping cone 4 to move. The gear 3 is rotatably mounted on the slider 7. The one-way damper is connected to the gear 3, which meshes with the rack 2. The rack 2 is fixedly mounted on the frame 1 and parallel to the linear rail 6. The clamping cone 4 and clamping cylinder 5 form part of the support and clamping mechanism. As the diameter of the cloth roll clamped by the clamping cone 4 increases, the center position of the cloth roll continues to rise, driving the support and clamping mechanism to gradually rise, and in turn driving the slider 7 to rise on the linear rail 6. The one-way damper ensures that the rotation of the gear 3 is not affected as the slider 7 rises on the linear rail 6, allowing the entire support and clamping mechanism to rise freely. When the clamping cylinder 5 drives the clamping cone 4 back, and the entire support and clamping mechanism automatically descends, gear 3 rotates in the opposite direction. The one-way damper generates resistance, which reduces the rotation speed of gear 3, thereby achieving a slow descent of the support and clamping mechanism and preventing damage from free fall. The descent speed of the support and clamping mechanism can be adjusted by adjusting the damping strength of the damper.

[0022] Furthermore, a safety cylinder 8 is mounted at the lower end of the frame 1, positioned vertically and facing upward. Its piston rod is connected to a positioning rod 9. A positioning portion 10 is provided on the lower end of the slider 7 or the clamping cylinder 5, configured to contact the positioning rod 9. After the support and clamping mechanism descends, the telescopic rod of the safety cylinder 8 extends a specific distance, allowing the positioning rod 9 to rise to a designated position to catch the descending slider 7 or clamping cylinder 5. Finally, the telescopic rod of the safety cylinder 8 retracts and resets, allowing the support and clamping mechanism to descend to its designated position, achieving a safe and accurate reset of the support and clamping mechanism.

[0023] Furthermore, the safety cylinder 8 is interlocked with the clamping cylinder 5 via a solenoid valve. The safety cylinder 8 is linked to the clamping cylinder 5 via the solenoid valve. After the piston rod of the clamping cylinder 5 is retracted, that is, after the clamping cone 4 is withdrawn, the piston rod of the safety cylinder 8 is extended, driving the positioning rod 9 to rise.

[0024] Further, described safety cylinder 8 is connected with timer. After the telescopic rod of safety cylinder 8 stretches out, give signal to timer, and timer controls the telescopic rod of safety cylinder 8 to retract according to set time timing after receiving signal.

[0025] Furthermore, the clamping cone 4 is connected to the piston rod of the clamping cylinder 5 via a connecting plate 11. A guide rod 12 is fixedly connected to the connecting plate 11. The slider 7 is provided with a guide hole for the guide rod 12 to move through, and a linear bearing 13 is installed in the guide hole. The cooperation between the guide rod 12 and the linear bearing 13 ensures that the clamping cylinder 5 drives the clamping cone 4 more smoothly.

[0026] Furthermore, a limit plate is installed on the guide rod 12. The limit plate limits the stroke of the clamping cone 4. Alternatively, the guide rod 12 with its own limit function can be used in conjunction with a linear bearing 13 to limit the stroke of the guide rod 12.

[0027] Furthermore, the clamping cone 4 is rotatably mounted on the connecting plate 11 .

[0028] Furthermore, the linear rail 6 is composed of two parallel slide rails 14, and both sides of the slider 7 are respectively mounted on the two slide rails 14. The linear rail 6 composed of the two parallel slide rails 14 makes the operation of the slider 7 more stable.

[0029] It is worth mentioning that the technical features such as the safety cylinder 8 and the clamping cylinder 5 involved in the patent application of the present invention should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement method of these technical features can be selected by conventional means in the field and should not be regarded as the inventive point of the patent of the present invention. The patent of the present invention will not be further elaborated.

[0030] The above describes in detail the preferred specific embodiments of the present invention. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solutions that can be obtained by technicians in this technical field through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of existing technologies should be within the scope of protection determined by the claims.
