Description

Technical Field

[0001] The present application relates to the field of polytetrafluoroethylene tape winding, and in particular to a polytetrafluoroethylene tape surface oil treatment and winding device. Background Art

[0002] When the PTFE tape is processed, it needs to be stretched. Stretching is often achieved by directly applying an external tensile force to the PTFE tape.

[0003] In some cases, in order to improve the production efficiency of the PTFE tape, automated equipment is used for stretching. Automated equipment for stretching often uses a rotatable roller to drive the PTFE tape in one direction, and then uses another device to apply resistance to the PTFE tape, so that the PTFE tape is subjected to external resistance during the conveying process in that direction. The external resistance provides a reaction force in the opposite direction to the above direction, causing the PTFE tape to deform due to tension.

[0004] However, the device applying resistance applies a fixed force to the PTFE belt, which will cause the PTFE belt to have a large tensile load limit in some positions and a small tensile load limit in some positions due to its own problems. Then, when the PTFE belt is subjected to a constant tensile force, some positions are prone to tensile damage or insufficient stretching. Summary of the invention

[0007] Furthermore, the anti-rotation assembly includes: a first abutment member and a second abutment member; the first abutment member is connected to the inner wall surface of the stretching chamber, and the second abutment member is connected to the anti-rotation roller; the first abutment member abuts against the second abutment member, and when the driving force applied to the anti-rotation roller reaches a preset force, the first abutment member slides relative to the second abutment member.

[0008] Furthermore, the anti-rotation assembly further includes: a control member; the control member is used to apply a variable pressure to the first abutment member close to the second abutment member.

[0009] Further, the first abutment member includes: a first connecting plate and a plurality of first protrusions arranged on the first connecting plate; the second abutment member includes: a second connecting plate and a plurality of second protrusions arranged on the second connecting plate; a first gap capable of accommodating the second protrusions is formed between the plurality of first protrusions; a second gap capable of accommodating the first protrusions is formed between the plurality of second protrusions; the anti-rotation assembly also includes an elastic member, which is used to apply an elastic force to the first connecting plate close to the second connecting plate.

[0011] Furthermore, the elastic member applies a variable elastic force to the first connecting plate close to the second connecting plate by means of a compression spring.

[0012] Furthermore, the winding device includes: a winding roller, a power roller and a guide roller; the guide roller is used to guide the polytetrafluoroethylene tape; the winding roller is used to wind the polytetrafluoroethylene tape, and the power roller is used to drive the polytetrafluoroethylene tape; the driving member is also used to drive the winding roller and the power roller to rotate; a torque sensor is arranged between the driving member and the power roller, and when the value displayed by the torque sensor exceeds a preset torque, the elastic member applies a gradually decreasing elastic force to the first connecting plate close to the second connecting plate.

[0016] The beneficial effects of this application are:

[0017] By arranging a heating device, the polyfluoro tape will become easier to stretch after passing through the heating chamber. When the polyfluoro tape passes through the stretching device, the anti-rotation roller and the stretching chamber will form a hindered rotation connection due to the setting that the anti-rotation roller is connected to the inner wall of the stretching chamber through the anti-rotation assembly. The polyfluoro tape bypasses the anti-rotation roller and the driving roller in turn. When the polyfluoro tape receives a certain tensile force, the anti-rotation roller will not rotate, thereby stretching. However, if the anti-rotation roller still does not rotate when the tensile force reaches the preset force of the anti-rotation roller, the polyfluoro tape will be subjected to excessive tensile force, and the polyfluoro tape may be damaged by stretching. In the present application, the anti-rotation roller is rotated relative to the stretching chamber when the force it receives is large. Therefore, during the stretching process, the polyfluoro tape will not be damaged or insufficiently stretched due to the different tensile load limits of certain positions of the polyfluoro tape, thereby improving the quality of the polyfluoro tape after stretching.

[0039] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0040] Reference Figure 1-11 ,

[0041] Example 1

[0042] A polytetrafluoroethylene tape surface oil treatment and winding device comprises: a heating device 1, a stretching device 2 and a winding device 3.

[0043] The heating device 1 is used to form a heating chamber for the PTFE tape to pass through. The stretching device 2 is used to form a stretching chamber for the PTFE tape to pass through. The winding device 3 is used to make the PTFE tape pass through the heating chamber and the stretching chamber in sequence and then be wound up.

[0044] The stretching device 2 includes: a stop roller 4, a driving roller 5, a stop assembly 6 and a driving member 7. The driving member 7 is used to drive the driving roller 5 to rotate or to make the driving roller 5 stationary. The driving member 7 is a motor. The stop roller 4 is connected to the inner wall surface of the stretching chamber through the stop assembly 6; a plurality of the stop rollers 4 and the driving rollers 5 are provided, and the polytetrafluoroethylene belt passes around the plurality of stop rollers 4 and the plurality of driving rollers 5 in sequence. The stop assembly 6 is used to form a blocked rotation connection between the stop roller 4 and the stretching chamber; when the driving force applied to the stop roller 4 reaches a preset force, the stop roller 4 rotates relative to the stretching chamber.

[0045] The anti-rotation roller 4 is difficult to rotate, and the driving roller 5 rotates to drive the PTFE belt. The friction between the PTFE belt and the anti-rotation roller 4 is the external force that prevents the PTFE belt from moving. Then the PTFE belt will be stretched, thus achieving the stretching of the PTFE belt. However, in some cases, if the friction between the PTFE belt and the anti-rotation roller 4 is too high, the driving roller 5 needs to use a greater force to enable the PTFE belt to be transmitted. At this time, the pulling force on the PTFE belt is too large, which can easily cause the PTFE belt to be over-stretched and damaged.

[0046] In this embodiment, the obstructed rotation connection refers to the interference of external forces, which makes it difficult for the anti-rotation roller 4 to rotate. The external interference can be an external force obstruction that restricts movement or a friction obstruction of physical contact. In this embodiment, the friction obstruction of physical contact is preferably used. At this time, the anti-rotation component 6 is a plate body arranged on the inner wall surface of the stretching chamber. The plate body contacts the end of the anti-rotation roller 4 to generate a large friction force. One of the specific schemes is that the end of the anti-rotation roller 4 abuts against the inner wall surface of the stretching chamber, and the friction between the end of the anti-rotation roller 4 and the inner wall surface of the stretching chamber hinders the anti-rotation roller 4 from rotating. However, when the driving force applied to the anti-rotation roller 4 reaches a preset force, the rotation of the anti-rotation roller 4 relative to the stretching chamber is caused by the driving force applied to the anti-rotation roller 4 being greater than the friction applied to the anti-rotation roller 4.

[0047] The method of first heating the PTFE tape and then stretching it can make use of thermal expansion and contraction to better stretch it.

[0048] Example 2

[0049] The difference from Example 1 is:

[0050] The anti-rotation assembly 6 includes: a first abutment 61 and a second abutment 62. The first abutment 61 is connected to the inner wall of the stretching chamber, and the second abutment 62 is connected to the anti-rotation roller 4. The first abutment 61 abuts against the second abutment 62, and when the driving force applied to the anti-rotation roller 4 reaches a preset force, the first abutment 61 slides relative to the second abutment 62. In this embodiment, the first abutment 61 and the second abutment 62 are both plate bodies, and preferably the first abutment 61 and the second abutment 62 are both plate bodies with a rubber wear-resistant layer, and the first abutment 61 and the second abutment 62 abut through the rubber wear-resistant layer. After a period of use, if the first abutment 61 and the second abutment 62 are worn, the rubber wear-resistant layer can be replaced to ensure the normal operation of the equipment. In order to better replace the rubber wear-resistant layer, in this embodiment, the rubber wear-resistant layer is detachably connected to the first abutment 61 or the second abutment 62.

[0051] Example 3

[0052] The difference from Example 2 is:

[0053] The first abutment member 61 includes: a first connection plate 611 and a plurality of first protrusions 612 disposed on the first connection plate 611. The second abutment member 62 includes: a second connection plate 621 and a plurality of second protrusions 622 disposed on the second connection plate 621. A first clamping gap capable of accommodating the second protrusions 622 is formed between the plurality of first protrusions 612. A second clamping gap capable of accommodating the first protrusions 612 is formed between the plurality of second protrusions 622. Both the first protrusion 612 and the second protrusion 622 are spheres.

[0054] The second connecting plate 621 is fixed to the anti-rotation roller 4. A plurality of guide members 63 are arranged on the first connecting plate 611; the guide members 63 are used to connect the first connecting plate 611 to the inner wall surface of the stretching chamber. The guide members 63 are used to guide the first connecting plate 611 in the direction of approaching and moving away from the second connecting plate 621. Among them, the first guide member 63 in this embodiment is a telescopic rod, one end of which is fixed to the inner wall surface of the stretching chamber, and the other end is fixed to the first connecting plate 611. The anti-rotation assembly 6 also includes an elastic member 64, and the elastic member 64 is used to apply an elastic force to the first connecting plate 611 to approach the second connecting plate 621. In this embodiment, the elastic member 64 adopts a spring 69, one end of which is in contact with the first connecting plate 611, and the other end is connected to the inner wall surface of the connecting chamber, and the extension direction of the spring 69 matches the telescopic rod. The spring 69 makes the first connecting plate 611 and the second connecting plate 621 resist each other, and when the second connecting plate 621 rotates with the anti-rotation roller 4, under the action of the first protrusion 612 and the second protrusion 622, the first connecting plate 611 moves away from the second connecting plate 621, so that when the driving force applied to the anti-rotation roller 4 reaches a preset force, the anti-rotation roller 4 rotates relative to the stretching chamber.

[0055] In this solution, the arrangement of the first protrusion 612 and the second protrusion 622 can greatly reduce the degree of wear, thereby increasing the service life of the first abutment member 61 and the second abutment member 62 .

[0056] In other embodiments, the anti-rotation assembly 6 further includes: a control member 65; the control member 65 is used to apply a variable pressure to the first abutment member 61 close to the second abutment member 62. The control member 65 is a hydraulic cylinder provided on the inner wall of the stretching chamber, the push rod 651 of the hydraulic cylinder is located inside the stretching chamber, and the cylinder body of the hydraulic cylinder is located outside the stretching chamber. A push plate 652 is provided on the push rod 651 of the hydraulic cylinder, the push plate 652 abuts against one end of the spring 69, and the other end of the spring 69 abuts against the first connecting plate 611, so that the push plate 652 can be pushed to move to different positions by the push rod 651 of the hydraulic cylinder to control the elastic force of the spring 69, that is, the elastic member 64 applies a variable elastic force close to the second connecting plate 621 to the first connecting plate 611 by compressing the spring 69. The size of the preset force is controlled, so that when the driving force applied to the anti-rotation roller 4 reaches a preset force, the preset force of the rotation of the anti-rotation roller 4 relative to the stretching chamber can be adjusted.

[0057] Example 4

[0058] The difference from Example 3 is that the spring 69 is replaced by a fixed tube 67 and a piston plate 68. The fixed tube 67 is fixed to the first connecting plate 611, the piston plate 68 is fixed to the push rod 651 of the hydraulic cylinder, and the fixed tube 67 is filled with gas. The push rod 651 of the hydraulic cylinder drives the piston plate 68 to move to different positions in the fixed tube 67 to compress the gas in the fixed tube 67, so that the fixed tube 67 generates different pressures on the first connecting plate 611, thereby also being able to control the size of the preset force, so that when the driving force on the anti-rotation roller 4 reaches a preset force, the preset force in the rotation of the anti-rotation roller 4 relative to the stretching chamber can be adjusted.

[0059] Example 5

[0060] Based on the above embodiments,

[0061] The winding device 3 includes: a winding roller 8, a power roller 81 and a guide roller 82. The guide roller 82 is used to guide the polytetrafluoroethylene tape; the winding roller 8 is used to wind the polytetrafluoroethylene tape, and the power roller 81 is used to drive the polytetrafluoroethylene tape; the driving member 7 is also used to drive the winding roller 8 and the power roller 81 to rotate.

[0062] In some embodiments, the driving member 7 keeps the driving roller 5 stationary, and a torque sensor is arranged between the driving member 7 and the power roller 81. When the value displayed by the torque sensor exceeds a preset torque, the elastic member 64 applies a gradually decreasing elastic force close to the second connecting plate 621 to the first connecting plate 611. This avoids the situation in which the PTFE belt is subjected to excessive tensile force in some cases, resulting in tensile damage to the PTFE belt, and better protects the PTFE belt.

[0063] In other solutions, the driving member 7 rotates the driving roller 5, and a torque sensor is arranged between the driving member 7 and the driving roller 5. When the value displayed by the torque sensor exceeds a preset torque, the elastic member 64 applies a gradually decreasing elastic force close to the second connecting plate 621 to the first connecting plate 611. This avoids the situation in which the PTFE belt is subjected to excessive tensile force in some cases, resulting in tensile damage to the PTFE belt, and better protects the PTFE belt.

[0064] In the above solution, the elastic member 64 applies a gradually decreasing elastic force to the first connecting plate 611 approaching the second connecting plate 621 , which is achieved through the control member 65 .

[0065] Specifically, the winding device 3 also includes: a bracket 83, a cylinder 84, a movable seat 85 and a fixed frame 86; the bracket 83 is used to install the winding roller 8 and the power roller 81; the movable seat 85 is arranged on the fixed frame 86, and the bracket 83 is fixed to the movable seat 85; the cylinder 84 is used to drive the movable seat 85 to move relative to the fixed frame 86. The fixed frame 86 is placed on the ground. The movable seat 85 is adjusted in position to prevent the winding roller 8 from deviating and to keep the polytetrafluoroethylene tape wound to the specified position of the winding roller 8 at all times.

[0066] Specifically, a plurality of transmission rollers are rotatably connected in the heating chamber; the plurality of transmission rollers are rotatably connected to the inner wall surface of the heating chamber; the polytetrafluoroethylene belt passes around the plurality of transmission rollers in sequence. The plurality of transmission rollers can make the length of the polytetrafluoroethylene belt in the heating chamber greater than the circumference of the heating chamber.

[0067] Specifically, a condensation chamber 9 is formed below the stretching chamber; a gas transfer component is arranged between the stretching chamber and the condensation chamber 9, and the gas transfer component is used to add the air in the stretching chamber to the condensation chamber 9; and a discharge port is formed in the condensation chamber 9. The hot air in the stretching chamber is sucked into the condensation chamber 9 in time, and the hot air in the condensation chamber 9 is pre-cooled to liquefy into liquid, and then discharged outward at the discharge port, thereby preventing the hot air from staying in the stretching chamber for a long time to form liquid in the stretching chamber, and preventing the liquid from dripping on the polytetrafluoroethylene tape to affect the stretching of the polytetrafluoroethylene tape and the quality of the polytetrafluoroethylene tape itself. Among them, the gas transfer component is an air pump.
