[0014] A high-toughness PVC reinforced film calendering and stretching processing technology is applied to the above-mentioned high-toughness PVC reinforced film calendering and stretching device, comprising the following steps: S1. First, by rotating the adjusting screw and the screw transmission of the adjusting nuts, the multiple cross bars can be driven to move laterally. When the cross bars move, the two connecting rods can be driven to move. When the connecting rods move, the slide plate can be driven to move laterally, thereby driving the pressure roller to move laterally and adjusting the gap between the pressure roller and the corresponding support roller assembly.

[0015] It is to be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.

[0016] Beneficial effects: In the present invention, the adjusting mechanism is set up, and the multiple cross bars can be driven to move laterally by rotating the adjusting screw under the threaded transmission action of the multiple adjusting nuts. When the cross bars move, the two connecting rods can be driven to move, so that the position of the pressing mechanism can be adjusted laterally, so that the gap between the pressing mechanism and the supporting roller assembly can be adjusted, which is convenient for calendering PVC films of different thicknesses; In the present invention, by means of the provided pressing mechanism, when the connecting rod moves along with the cross bar, the sliding plate can be driven to move laterally, thereby driving the pressing roller to move laterally, and adjusting the gap between the pressing roller and the corresponding supporting roller assembly, so as to facilitate the rolling of PVC films of different thicknesses; In the present invention, the hot melt conveying mechanism is set up, and the corresponding driving gears can be driven to rotate by starting two driving motors.

At the same time, multiple electric heating rods can be energized. After the electric heating rods are energized, the heat emitted by the electric heating rods can heat-melt the PVC film, so that when the PVC film is rolled by the pressing roller, it can be convenient for the PVC film to be shaped; In the present invention, by means of the winding mechanism, after the reel for winding the PVC film is placed between the two chucks, the moving tube can be driven to move by operating the moving component, so that the chuck moves and clamps the reel. After that, the transmission component can rotate after receiving the power of the driving motor, so as to drive the driving shaft to rotate. Then, under the driving action of the moving tube, the chuck can be driven to rotate, and the reel can be driven to rotate to wind the PVC film.

[0017] The present invention can adjust the positions of multiple pressing rollers simultaneously when calendering the PVC film, so that the multiple pressing rollers can be adjusted according to the production of PVC films of different thicknesses, and when the PVC is rolled up, the power of the driving motor can be effectively dispersed, so that energy consumption can be effectively reduced when producing the PVC film.

[0023] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present invention. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. appearing in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0024] Example 1: Reference Figure 1-Figure 8 The high-toughness PVC reinforced film calendering and stretching device of this embodiment is mainly composed of a calender frame 1, a discharging machine, an adjusting mechanism, a hot melt conveying mechanism and a winding mechanism.

[0025] The calender frame 1 serves as the basic supporting structure of the entire device, and a discharging machine is arranged on one side thereof. The discharging machine is responsible for melting the PVC raw materials and automatically outputting them to the calender frame 1 for processing.

[0026] like Figure 4 As shown, the design of the adjustment mechanism is mainly to adjust the calendering thickness of the PVC film. Specifically, the adjustment mechanism includes an adjustment screw 15 rotatably connected to the calender frame 1, and a plurality of pressing mechanisms are connected to the adjustment screw 15 by threads. A plurality of sliding holes are symmetrically provided on the calender frame 1, and each pressing mechanism passes through two corresponding sliding holes through two connecting rods 13, and is connected to the top inner walls of both sides of the calender frame 1. A cross bar 14 is fixedly installed at the bottom of the connecting rod 13, and an adjustment nut 22 is fixedly installed on one side of the cross bar 14. The adjustment screw 15 passes through a plurality of cross bars 14 and the adjustment nut 22, and is threadedly connected to the adjustment nut 22. Therefore, when the adjustment screw 15 is rotated, through the thread transmission effect, the plurality of cross bars 14 can be driven to move laterally, and then the connecting rod 13 and the pressing mechanism can be driven to move, so as to adjust the gap between the pressing mechanism and the support roller assembly, thereby adapting to the calendering requirements of PVC films of different thicknesses.

[0027] like Figure 4 As shown, the pressing mechanism is mainly composed of a pressing roller 12, and both ends of the pressing roller 12 are slidably connected to a slide rail 10 through a slide plate 11, and the slide rail 10 is fixedly installed on one inner wall of the calender frame 1. The top of the connecting rod 13 is fixedly connected to the bottom of the slide plate 11, so when the connecting rod 13 moves, it will drive the slide plate 11 and the pressing roller 12 to move together, so as to achieve precise adjustment of the calendering gap.

[0028] like Figure 1 As shown, in order to facilitate the rotation and positioning of the adjusting screw 15, a support plate 17 is also fixedly installed on the calender frame 1, and the adjusting screw 15 passes through the support plate 17 and is rotatably connected to the support plate 17. A positioning gear 18 is fixedly installed on one side of the support plate 17, and the adjusting screw 15 passes through the positioning gear 18. A hand wheel 16 is fixedly installed on one end of the adjusting screw 15, and a handle bar 19 is slidably connected to the eccentric position of the hand wheel 16, and an arc-shaped rack 20 is fixedly installed on one end of the handle bar 19, and the arc-shaped rack 20 is movably meshed with the positioning gear 18. A tension spring 21 is sleeved on the handle bar 19, and the two ends of the tension spring 21 are respectively fixedly connected to one side of the hand wheel 16 and the arc-shaped rack 20. When it is necessary to rotate the adjusting screw 15, first pull the handle bar 19 to drive the arc-shaped rack 20 to disengage from the positioning gear 18, and release the braking effect on the hand wheel 16. Then the hand wheel 16 can be turned to drive the adjusting screw 15 to rotate. After the adjustment is completed, the handle rod 19 is released, and the tension spring 21 drives the handle rod 19 and the arc-shaped rack 20 to reset and re-engage with the positioning gear 18 to achieve braking of the adjusting screw 15.

[0029] like Figure 3 and 5 As shown, the hot melt conveying mechanism is mainly responsible for the conveying and hot melting of the PVC film. It includes two driving motors 5 and a plurality of support roller assemblies. The support roller assembly runs through the calender frame 1 and is rotatably connected to the calender frame 1, and a plurality of support roller assemblies are staggered with a plurality of pressing mechanisms. The output shaft of the driving motor 5 extends to the outside of the calender frame 1 and is connected to one of the support roller assemblies. The support roller assembly is mainly composed of a hot roller 3, and a plurality of electric heating rods 4 are fixedly installed at equal intervals in the hot roller 3. When the driving motor 5 is started, the hot roller 3 is driven to rotate, thereby realizing the conveying of the PVC film. At the same time, the electric heating rod 4 will emit heat after being energized to hot-melt the PVC film, making it easier to shape under the pressure of the pressing roller 12.

[0030] In order to enhance the synchronous rotation effect of the heat roller 3, a synchronous wheel 8 is fixedly sleeved on the rotating shaft 2 of the heat roller 3, and a transmission sleeve of multiple synchronous wheels 8 on the same side is provided with a same synchronous belt 81. In this way, when one heat roller 3 is driven to rotate by the driving motor 5, the transmission effect of the synchronous wheel 8 and the synchronous belt 81 will drive the other heat rollers 3 to rotate synchronously.

[0031] like Figure 5 and Figure 8 As shown, the winding mechanism is responsible for winding the PVC film after calendering and stretching. It mainly includes a support frame 31 fixedly mounted on one side of the top of the calender frame 1, a collar 32 fixedly mounted on the support frame 31, and a drive shaft 29 is rotatably connected to the collar 32. A moving tube 33 is slidably sleeved on the drive shaft 29, a chuck 34 is fixedly mounted on one end of the moving tube 33, and a positioning shaft 41 is fixedly mounted on one side of the chuck 34, which is used to position and support the reel for winding the PVC film. A moving component is also connected to the support frame 31, and the moving component is connected to the moving tube 33. After the reel is placed between the two chucks 34, the moving tube 33 can be driven to move by operating the moving component, and then the chuck 34 can be driven to move to clamp the reel.

[0032] like Figure 8 As shown, the moving assembly is mainly composed of a connecting ring 35 that is rotatably sleeved on the moving tube 33, and a connecting plate 36 is fixedly installed on the top of the connecting ring 35. A threaded member is connected to the top of one side of the connecting plate 36, and the threaded member is installed on the top of the support frame 31. The threaded member includes a fixed plate 37 and a transmission nut 38 fixedly installed on the top of the support frame 31, and a transmission screw 39 is rotatably connected to the top of one side of the connecting plate 36. The transmission screw 39 passes through the fixed plate 37 and the transmission nut 38 respectively and is threadedly connected to the transmission nut 38. Therefore, when the transmission screw 39 is rotated, the connecting plate 36 and the connecting ring 35 are driven to move through the threaded transmission action, and then the moving tube 33 and the chuck 34 are driven to move.

[0033] Example 2: Reference Figure 3 This embodiment is based on the first embodiment. Regarding the high-toughness PVC reinforced film calendering and stretching device proposed in the first embodiment, in order to realize the driving of the winding mechanism by the driving motor 5, a transmission assembly is also designed. The transmission assembly includes a protection box 9 fixedly installed on one side of the calender frame 1, and the driving gear 6 and the transmission gear 7 are both located in the protection box 9. A connecting shaft 26 is rotatably connected to the inner wall of the top side of the protection box 9, and a connecting bevel gear 28 is fixedly installed on the top of the connecting shaft 26. A driven bevel gear 30 is fixedly sleeved on the driving shaft 29, and the connecting bevel gear 28 is meshed with the driven bevel gear 30. A transmission shaft 24 is also rotatably connected in the protection box 9, and a driving bevel gear 40 and a worm gear 25 are fixedly sleeved on the transmission shaft 24. A worm 23 is fixedly sleeved on the output shaft of the driving motor 5, and the worm 23 is meshed with the worm gear 25. Therefore, when the driving motor 5 is started, it will drive the worm 23 to rotate, and then drive the driving bevel gear 40 to rotate through the transmission action of the worm gear 25 and the transmission shaft 24. The active bevel gear 40 then drives the connecting bevel gear 28 and the driven bevel gear 30 to rotate through the transmission action of the driving bevel gear 27 and the connecting shaft 26, and finally drives the driving shaft 29 and the chuck 34 to rotate, thereby realizing the winding of the PVC film.

[0034] The present invention provides a high-toughness PVC reinforced film calendering and stretching processing technology, which is applied to the above-mentioned high-toughness PVC reinforced film calendering and stretching device, comprising the following steps: S1. First, by rotating the adjusting screw 15, under the threaded transmission action of the multiple adjusting nuts 22, the multiple cross bars 14 can be driven to move laterally. When the cross bars 14 move, the two connecting rods 13 can be driven to move. When the connecting rods 13 move, the slide plate 11 can be driven to move laterally, thereby driving the pressure roller 12 to move laterally and adjust the gap between the pressure roller 12 and the corresponding support roller assembly. In this way, the gap between the pressure roller 12 and the corresponding hot roller 3 can be adjusted according to the thickness of the produced PVC film; S2. After placing the reel for winding the PVC film between the two chucks 34, the transmission screw 39 is rotated to move laterally under the threaded transmission action of the transmission nut 38, thereby driving the moving tube 33 to move laterally through the connecting plate 36 and the connecting ring 35, so as to realize the positioning and clamping of the reel by the chucks 34; S3, use the discharging machine to output the PVC material in the molten state, and staggeredly wind it between multiple hot rollers 3 and pressure rollers 12, then start the driving motor 5 to drive the corresponding driving gear 6 to rotate, at this time, under the meshing transmission action with the corresponding transmission gear 7, it can drive the same hot roller 3 to rotate, when the rotating shaft 2 rotates with the transmission gear 7, it can drive multiple hot rollers 3 to rotate under the transmission action of multiple synchronous wheels 8 and synchronous belts 81, so that the PVC film can be transported, and under the pressure of the corresponding pressure roller 12, the PVC film can be rolled, at the same time, multiple electric heating rods 4 can be energized, and the heat emitted by the electric heating rods 4 after being energized can heat-melt the PVC film, so that when the PVC film is rolled by the pressure roller 12, it can be convenient to shape the PVC film, and the PVC film output between the pressure roller 12 and the hot roller 3 can be cooled and shaped under the action of the surrounding air; S4. After the calendered PVC film is calendered, the driving motor 5 can be suspended, and then the PVC film is fixed on the reel, and then the driving motor 5 is started. At this time, the transmission shaft 24 can be driven to rotate under the meshing transmission of the worm 23 and the worm wheel 25. When the transmission shaft 24 rotates, the connecting shaft 26 can be driven to rotate under the meshing transmission of the active bevel gear 40 and the driving bevel gear 27. When the connecting shaft 26 rotates, the driving shaft 29 can be driven to rotate under the meshing transmission of the connecting bevel gear 28 and the driven bevel gear 30. Then, the chuck 34 can be driven to rotate through the transmission of the moving tube 33, so as to provide driving force for the reel and wind the PVC film. Therefore, in the previous description, the driving force of the driving motor 5 can be dispersed and transmitted to the chuck 34, so as to improve the power utilization efficiency of the driving motor 5, and effectively reduce energy consumption when actually producing PVC film.

[0035] However, as is well known to those skilled in the art, the working principles and wiring methods of the electric heating rod 4 and the drive motor 5 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0036] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention; the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
