Description

Technical Field

[0001] The invention relates to the technical field of resin calendering and winding, in particular to a calendering and winding device for processing PTFE dispersed resin. Background Art

[0002] PTFE, commonly known as the "king of plastics", is the most widely used fluorine-containing polymer with excellent chemical stability, corrosion resistance, sealing, high lubricity and non-stickiness, electrical insulation and good anti-aging resistance. It is widely used in electronics, chemical industry, machinery, construction, textile and other fields. The methods for producing PTFE resin usually include suspension method and dispersion method. The resins obtained are called suspension resin and dispersion resin respectively. Dispersion resin is tetrafluoroethylene (TFE) monomer, which is dispersed into an emulsion state under the action of an emulsifier for polymerization. PTFE dispersion resin can be processed into flat strips. During processing, it needs to be calendered and stretched by a calendering roller, and then the calendered strips are wound up by a winding shaft.

[0003] In the prior art, only two sets of calendering rollers are used to calender the middle part of the rubber strip, and the rubber strip just calendered still has a certain elasticity. When the pressure is reduced during the winding process, a slight rebound phenomenon will occur, resulting in a large difference between the thickness of the wound rubber strip and the required thickness, which affects the quality of the product.

The driving motor is started to drive the winding shaft to rotate and reel, and the electric telescopic rod is started to push the lifting plate to move, so that the calendering rollers on the upper and lower sides can be pushed to move synchronously toward the middle to calender the rubber strip. The sliding frame is driven to slide intermittently horizontally by rotating the second screw, so as to adjust the position of the triangular block so that the side of the triangular block conflicts with the slope surface.

[0015] 2. The present invention provides a calendering and winding device for processing PTFE dispersed resin. When the device rotates and winds around the reel, it will drive the driving rod to rotate, thereby driving the inflation plate to perform piston movement in the inflation box, and the external gas is drawn into the inflation box through a one-way air inlet valve, and then squeezed through the one-way exhaust valve to be output into the first pipe, enter the annular cavity, and output into the connecting pipe, so that the air pressure in the connecting pipe increases, pushing the sliding rod to move, so that the extrusion shafts around it can fit tightly against the outer wall of the rubber strip to roll in contact, and at the same time will not affect the winding operation of the rubber strip.

[0025] The adjustment control 30 includes a control block 31 that slides in contact with the inner wall of the third pipe 28. The third pipe 28 is internally threaded with a first screw 32.

Both ends of the calendering roller 10 are respectively rotatably connected to lifting rods 38, and the lifting rods 38 are slidably connected to the guide frame 37 in the vertical direction. The lifting rods 38 are fixedly connected to a second spring 39 fixedly connected to the guide frame 37.

[0027] The adjusting member 11 includes a sliding frame 40 which is slidably connected to the fixed frame 2 in the horizontal direction, and a plurality of sets of triangular blocks 41 are evenly and fixedly connected to the sliding frame 40.

A scale 44 is fixedly connected to the side of the fixed frame 2.

[0028] In this embodiment, one end of the PTFE dispersed resin rubber strip 46 wound on the output shaft 4 is passed through between multiple groups of calendering rollers 10 and then fixed on the winding shaft 6, the driving motor 18 is started to drive the winding shaft 6 to rotate and reel, and the electric telescopic rod 36 is started to push the lifting plate 35 to move, so that the calendering rollers 10 on the upper and lower sides can be pushed to move toward the middle synchronously to calender the rubber strip 46, and the sliding frame 40 is driven to slide intermittently horizontally by rotating the second screw 43, so as to adjust the position of the triangular block 41, so that the side of the triangular block 41 is in conflict with the slope 42, and when the calendering rollers 10 on the upper and lower sides are squeezed to the set distance, they will not continue to approach, thereby achieving the desired rubber strip 4 6. At the same time, the required thickness of the rubber strip 46 can be determined by observing the scale reading corresponding to one end of the second screw 43 and the scale 44. During the calendering process, the lifting plate 35 will apply a large force to the guide frame 37 and the second spring 39, so that the lifting rod 38 and the calendering roller 10 are closely attached to the upper and lower surfaces of the rubber strip 46. At the same time, the second spring 39 will have a certain buffer, which can avoid the situation where the thickness of the rubber strip 46 is directly compressed too much and the resistance to the calendering roller 10 is too large. Through a variety of calendering rollers 10 arranged side by side, the progressive calendering of the rubber strip 46 can be achieved, so that the rubber strip 46 is gradually compressed to the required thickness before the subsequent winding operation is carried out.

[0029] When the winding shaft 6 rotates and winds, it will drive the driving rod 21 to rotate, thereby driving the inflation plate 20 to perform piston movement in the inflation box 19, and the external gas is drawn into the inflation box 19 through the one-way air inlet valve 23, and then squeezed through the one-way exhaust valve 24 to be output to the first pipe 22, enter the annular cavity 13, and output to the connecting pipe 12, so that the air pressure in the connecting pipe 12 increases, pushing the sliding rod 15 to move, so that the extrusion shafts 7 around can fit closely to the outer wall of the rubber strip 46 for resistance and rolling, and at the same time will not affect the winding operation of the rubber strip 46.

[0030] The air pressure in the connecting pipe 12 can be output to the annular pipe 26 through the second pipe 27, and then enter the third pipe 28, pushing the control block 31 to slide in the third pipe 28. Due to the movement of the inflatable plate 20, the connecting pipe 12 will be inflated intermittently, so that the air pressure in the annular pipe 26 gradually increases. When the air pressure increases to a set value, the control block 31 is pushed to a set position by the air pressure, so that the gas in the annular pipe 26 can be discharged through the third pipe 28 and the exhaust hole 29. By rotating the first screw 32, the adjustment The position of the control block 31 is adjusted so that the distance between the control block 31 and the exhaust hole 29 changes. When the control block 31 is away from the exhaust hole 29, the first spring 33 needs to be compressed to a greater extent to connect the exhaust hole 29 with the annular tube 26. At this time, the air pressure in the annular tube 26 and the connecting tube 12 is higher, otherwise the air pressure in the connecting tube 12 is reduced. The higher the air pressure in the connecting tube 12, the greater the driving force on the sliding rod 15, so that the resistance force of the extrusion shaft 7 to the outer wall of the rubber strip 46 is greater, and vice versa.

[0031] It should be noted that: as the rubber strip 46 is continuously wound, its diameter becomes larger and larger, and the extrusion shaft 7 is continuously pushed to the surroundings, but at this time, the air pressure can be stably controlled through the third pipe 28 and the control block 31, so that in the process of continuous movement of the extrusion shaft 7, the air pressure in the connecting pipe 12 is always kept in a relatively stable state. Once the air pressure is greater than the set value, it will be discharged through the exhaust hole 29 to avoid the damage of the rubber strip 46 caused by the continuous increase of the internal air pressure. The position corresponding to one end of the first screw 32 can be observed through the transparent third pipe 28, thereby realizing the adjustment of the required air pressure intensity.

[0032] It is worth noting that the PTFE dispersed resin has a large rebound resilience in a short time after calendering. If the rubber strip 46 conveyed during this process is not extruded and limited, it will cause the rubber strip 46 to rebound slightly and thicken during the winding process. The rubber strip 46 after winding is subjected to more uniform force and is wound more tightly, making it difficult to continue to rebound. After a period of shaping, the rebound performance is reduced, making the thickness relatively fixed during use.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
