Description

Technical Field

[0001] The utility model relates to the technical field of winding and unwinding systems, and more specifically, to a winding and unwinding system, a product obtained therefrom, a winding and unwinding composite system, and a product obtained therefrom. Background Art

[0002] A winding and unwinding device refers to a device that can continuously wind / unwind materials during the production process to cooperate with upstream and downstream transmissions and processing. The winding and unwinding device is widely used in fields such as coating and composite material preparation. Usually, the winding and unwinding device does not exist independently. Taking the product as a composite material as an example, the winding and unwinding device cooperates with downstream devices such as compounding devices to form a complete production system. In some production systems, in order to adapt to limited factory space, save the corresponding equipment layout space, and also to reduce problems such as difficult control of transmission tension caused by too long a roller path of the film roll between different devices, it is necessary to arrange the winding and unwinding device and other downstream devices relatively compactly.

[0003] However, although arranging compactly can solve the aforementioned problems, new problems will also arise. When installing, replacing, cleaning, or maintaining the adjacent device, the winding and unwinding device will form a certain degree of obstruction. It includes blocking adjacent downstream equipment in the front side direction, etc., and the operation is relatively inconvenient. And it is also not convenient to provide space by moving the winding and unwinding device, etc. Because even if it is reset after moving, there will be a position deviation, which is likely to cause a large winding and unwinding offset on the winding and unwinding side, affecting the corresponding production process and product quality. For such production systems, how to improve the inconvenience of installation and maintenance caused by compact arrangement and avoid the influence of offset as much as possible is particularly important.

[0004] Therefore, the prior art urgently needs an adjustable winding and unwinding system that is convenient for compact arrangement, conducive to device installation, maintenance, etc., and can avoid the influence of offset during use, as well as a corresponding complete winding and unwinding composite system, etc. Summary of the Utility Model

[0005] The utility model aims to overcome at least one of the above-mentioned deficiencies of the prior art, and provides a winding and unwinding system and a corresponding winding and unwinding composite system, which are convenient for compact arrangement and convenient for installation, maintenance, etc. of adjacent devices; while ensuring convenient installation and maintenance, the influence of offset on the winding and unwinding side is avoided.

[0006] The technical solution adopted by the present utility model is a winding and unwinding system, which includes a carrying bracket, a winding and unwinding device, a first-direction driving device, and a second-direction driving device; the first-direction driving device is installed on the carrying bracket, and the winding and unwinding device is installed on the first-direction driving device through the second-direction driving device; the first-direction driving device drives the winding and unwinding device to move in the first direction to send out or receive the winding and unwinding device, and the second-direction driving device drives the winding and unwinding device to move in the second direction to perform winding and unwinding deviation correction. Further, the first direction is the winding and unwinding direction of the winding and unwinding device, and the second direction is perpendicular to the winding and unwinding direction of the winding and unwinding device. In this application, the first-direction driving device drives the winding and unwinding device to send out or receive. On the one hand, during specific use, it can send out to form a compact production system, especially providing a smaller roller distance between the smaller winding and unwinding device and adjacent devices, improving the stability of the rollers. On the other hand, it can be received when not in use, increasing the space between the winding and unwinding device and adjacent devices in the first direction, thereby facilitating the installation, replacement, maintenance, or cleaning of adjacent devices in the first direction; at the same time, the first-direction driving device can stably move the winding and unwinding device, avoiding lateral deviation in the first direction, and facilitating the stable winding and unwinding position in the subsequent first direction; while the second-direction driving device can provide a deviation correction function during the winding and unwinding process, especially after sending out or receiving the winding and unwinding device, further improving the stability and accuracy of its transmission. Based on the winding and unwinding system of this application, it can be arranged compactly while facilitating the installation, maintenance, etc. of adjacent devices. At the same time, it avoids the influence of offset at the winding and unwinding end, ensuring stable and accurate winding and unwinding.

[0007] Further, the first-direction driving device includes a first slide rail, a first slider, a rack, a base, and a first driving motor; the first slide rail and the rack are fixed on the upper surface of the carrying bracket, the winding and unwinding device is installed on the base, the base is located above the carrying bracket, and the bottom of the base is provided with a first slider that cooperates with the first slide rail; the first driving motor is connected with a transmission shaft, the end of the transmission shaft is connected with the base, and a transmission gear is arranged on the transmission shaft. The first driving motor drives the transmission gear to cooperate with the rack to drive the base to move in the first direction. Through the cooperation and guidance of the slider and the slide rail, since the cooperation between the slider and the slide rail is relatively compact, obvious deviation can be avoided through its guidance; since the carrying bracket is usually fixed to the ground, and the rack and the slide rail are fixed to the carrying bracket, its installation and use are more stable; and it is not easy to have a position offset. Through the drive of the transmission shaft cooperating with the transmission gear, it can conduct to both sides of the winding and unwinding device through the transmission shaft, thereby promoting smooth movement; when a film roll is arranged on the winding and unwinding device, the transmission shaft and the gear can overcome its heavier load and stably drive.

[0008] Furthermore, rear mounting portions extend backward from both sides of the base; the first drive motor, the transmission shaft, and the transmission gears are all arranged between the rear mounting portions. The rear side of the wall panel is fixed to the rear mounting portions, and the rear mounting portions provide a mounting position for the wall panel, facilitating the arrangement of the rollers of the winding and unwinding device; meanwhile, a mounting space for the first drive motor, the transmission shaft, and the transmission gears is formed between the two rear mounting portions on both sides, with stable structural installation and small occupied space for the arrangement.

[0009] Furthermore, the first drive motor is a worm and worm gear motor and is arranged on the middle side of the transmission shaft; transmission gears are arranged on both sides of the first drive motor on the transmission shaft. Arranging the first drive motor on the middle side and arranging transmission gears on both sides of the first drive motor is beneficial for balanced driving on both the left and right sides, improving driving stability and synchronism; and balanced driving on both the left and right sides is also beneficial for avoiding wear caused by incomplete synchronization on both sides, and improving the service life of the winding and unwinding device.

[0010] Furthermore, the second-direction driving device includes a second slider, a second slide rail, and a second drive motor; the winding and unwinding device includes a bottom plate, and the second slider is arranged on the lower surface of the bottom plate; the second slide rail and the second drive motor are fixed to the upper surface of the first-direction driving device, such as being fixed to the upper surface of the aforementioned base; a hollow mounting opening is further arranged on the bottom plate, the second drive motor is located in the mounting opening, and the output end of the second drive motor abuts against the wall surface of the mounting opening. Further, the second drive motor is horizontally placed on the upper surface of the base. In this application, arranging the second drive motor in the mounting opening does not require additional space to be extended horizontally for the arrangement; meanwhile, the rigidity of the bottom plate in the horizontal direction can be utilized to improve driving stability; further, the output end of the second drive motor is directly abutted against the side wall of the mounting opening of the bottom plate.

[0011] Furthermore, the unwinding device includes a unwinding support and a unwinding shaft. The unwinding support is also provided with a tension-adjusting roller, a tension-detecting roller, and at least one guide roller. The relative positions of the tension-adjusting roller, the tension-detecting roller, and the guide roller are arranged so that the film roll on the unwinding shaft passes through the tension-adjusting roller, the tension-detecting roller, and the guide roller, and the first surface side of the film roll only contacts the surface of at most one roller among the tension-adjusting roller, the tension-detecting roller, or the guide roller. That is, the unwinding shaft is loaded with a film roll, and the first surface side of the film roll only contacts the surface of at most one roller among the tension-adjusting roller, the tension-detecting roller, and the guide roller. The first surface side is the surface side of the film roll used for compounding with downstream materials. Furthermore, at least the first surface side comprises a non-completely solid material. The unwinding device of the present application is applicable to film rolls with adhesive layers or other viscous materials on their surfaces to be compounded, which helps to ensure the integrity of the surface material and improve the quality of the subsequent composite material product. Furthermore, the film roll is a composite film roll, including a film layer and an adhesive layer, and the adhesive layer is arranged on the surface of the film layer; the first surface side is the exposed adhesive side of the film layer. Furthermore, when the unwinding device of the present application is used in the unwinding process before compounding, the side of the film roll used for compounding with other materials only passes through one roller surface at most, which can avoid contact with the roller surface as much as possible, thereby reducing the loss of surface material before compounding and ensuring a certain degree of flatness, such as the surface material includes a preliminarily solidified adhesive layer; so that in the subsequent specific compounding, the downstream material can be bonded flat, reducing bubbles and gaps between the bonding interfaces, so as to significantly improve the quality of the finished composite material. Moreover, the present application further detects the unwinding tension in real time through a tension detection roller, and cooperates with the tension adjustment roller to adjust the unwinding tension, to ensure that the unwinding surface is flat and smooth, and thus to ensure that no wrinkles are generated when compounding with downstream materials. Only a small number of rollers and a specific arrangement of rollers are required to reduce the loss of the exposed adhesive surface during the unwinding process, while ensuring the effects of unwinding tension control.

[0012] Furthermore, in the rewinding and unwinding device, a surface treatment layer is provided on the corresponding roller body that abuts against the first surface side of the film roll. Furthermore, the surface treatment layer is an anti-sticking layer; furthermore, the surface treatment layer is an anti-sticking layer of glue. Furthermore, when the first surface side of the film roll abuts against the surface of the tension adjustment roller, the tension adjustment roller is provided with a surface treatment layer; or, when the first surface side of the film roll abuts against the surface of the tension detection roller, the tension detection roller is provided with a surface treatment layer; or, when the first surface side of the film roll abuts against the surface of the guide roller, the corresponding guide roller body is provided with a surface treatment layer. When the film roll reaches the roller body abutting the first surface, and the exposed first surface side material reaches the abutting roller body, at this time, by providing an anti-sticking surface treatment layer on the corresponding roller body, it is beneficial to minimize the loss of the first surface side material; when the exposed material on the first surface side of the film roll is a glue layer, the surface treatment layer can be an anti-sticking layer of glue. Furthermore, the surface treatment layer is a release layer formed by coating a release agent.

[0013] Furthermore, the tension adjusting roller and the tension detecting roller are arranged adjacent to each other. Further, when it is a unwinding device, the tension adjusting roller and the tension detecting roller are sequentially arranged in the unwinding direction. Further, the guiding roller is arranged before or after the tension adjusting roller and the tension detecting roller. The adjacent arrangement of the tension adjusting roller and the tension detecting roller is beneficial to improving the accuracy of tension detection and tension adjustment; when the tension adjusting roller is adjusted, the adjacent tension detecting roller can immediately and accurately detect the corresponding tension, which is beneficial to more accurate tension control and adjustment. And the sequential arrangement of the tension adjusting roller and the tension detecting roller in the unwinding direction is beneficial to placing the detecting roller with unchanged roller position closer to the downstream compounding device, improving the tension stability between the unwinding and winding device and the compounding process. In addition, the guiding roller can also be arranged between the tension adjusting roller and the tension detecting roller. In the unwinding direction, the tension adjusting roller is arranged on the side close to the unwinding shaft, and the tension detecting roller is arranged on the side far from the unwinding shaft.

[0014] Furthermore, one tension adjusting roller, one tension detecting roller and one guiding roller are arranged on the unwinding and winding support. The unwinding and winding material film roll sequentially passes through the guiding roller, the tension adjusting roller and the tension detecting roller, and the film roll passes through while abutting against the tension adjusting roller through the first surface side, and passes through while abutting against the tension detecting roller and the guiding roller through the second surface side opposite to the first surface side. Only a very small number of rollers are needed to reduce the surface material loss of the film roll, achieve tension control and guide to the downstream compounding while unwinding smoothly. Since there are fluctuations and errors in the control of the running rollers in actual production, that is, the front and rear running rollers need to be adjusted in real time according to the tension condition to immediately adjust the driving speed of the corresponding rollers, so as to keep the basic tension consistent; and the simultaneous setting of the tension adjusting roller and the tension detecting roller in the unwinding device can strictly control the tension during the unwinding process, so as to facilitate the downstream material to be smoothly attached to the film roll.

[0015] Furthermore, the first surface of the film roll is coated with a release film layer; the rewinding and unwinding system also includes a peeling component configured to peel the release film layer before the film roll passes through the tension-adjusting roller and the tension-detecting roller. Furthermore, in the case of an unwinding device, a guide roller, a tension-adjusting roller, and a tension-detecting roller are sequentially arranged in the unwinding direction, and the peeling component is positioned between the tension-adjusting roller and the guide roller in the rolling direction. When the film roll has an adhesive layer on its surface, a release film is typically required to separate the adhesive layer on the outer coil from the film layer on the inner coil to facilitate winding and storage. To facilitate direct lamination after unwinding, the release film must be peeled off in advance. During the peeling process, the release film generates a certain degree of interference. Positioning the peeling component before the tension-adjusting roller facilitates immediate adjustment based on tension changes caused by the peeling process, thereby ensuring smooth and even unwinding while peeling. The stripping component particularly needs to be arranged before the tension adjustment roller so that the tension can be adjusted back to the required tension in time using the tension adjustment roller.

[0016] Furthermore, the guide roller is located in front of the reel, with its upper surface higher than the lower surface of the reel. The reel releases the film roll from the lower side and passes over the upper surface of the guide roller. The tension adjustment roller is located below the guide roller. The tension detection roller includes a detection roller body, and the tension sensor is located on the side opposite the side of the detection roller body that abuts the film roll. Furthermore, the tension detection roller is higher than the tension adjustment roller, and the tension sensor is located below the detection roller body. This arrangement allows the film roll to be pulled and stretched, and the tension is detected as the tension detection roller guides the film roll to the downstream laminating device, reducing the number of rollers required for the reel and avoids material loss on the film roll surface due to excessive roller transmission.

[0017] Furthermore, the rewinding and unwinding support comprises a base plate and wall panels fixed to either side of the base plate; the wall panels are provided with arcuate through-holes and are equipped with a swing arm drive mechanism; the end of the tension adjustment roller is connected to the swing arm drive mechanism mounted on the wall panel via the arcuate through-holes; the swing arm drive mechanism is driven to change the position of the tension adjustment roller in the direction of the arcuate through-holes. When the swing arm drive mechanism drives the tension adjustment roller in the direction of the arcuate through-holes, tension adjustment is more natural, avoiding friction between the roller and the film roll surface caused by a straight forward or straight backward movement, thereby improving the unwinding effect.

[0018] Further, the swing arm driving mechanism includes a fixed cylinder base, a cylinder, a swing arm fixing plate, and a swing arm rod; the fixed cylinder base is installed on the outer side of the wall panel, and the installation end of the cylinder is rotatably connected to the fixed cylinder base; the swing arm fixing plate is installed on the outer side of the wall panel, one end of the swing arm rod is rotatably connected to the swing arm fixing plate, the outer side of the other end of the swing arm rod is connected to the output end of the cylinder, and the inner side is connected to the end of the tension adjusting roller. Further still, the swing arm rod includes a main rod and a connecting rod, a rotating shaft is provided on the swing arm fixing plate, the rotating shaft passes through the main rod and the connecting rod, and the main rod and the connecting rod rotate synchronously with the rotating shaft, and the output end of the cylinder is connected to the other end of the connecting rod.

[0019] Further, the winding and unwinding bracket includes a bottom plate and wall panels fixed on both sides of the bottom plate; arc-shaped through holes are provided on the wall panels, and a swing arm driving mechanism is installed on the wall panels; the end of the tension adjusting roller is connected to the swing arm driving mechanism installed on the wall panel through the arc-shaped through hole; the lowest point of the arc of the arc-shaped through hole is directly below the guiding roller; and the heights of both ends of the arc of the arc-shaped through hole are the same. Further, the inner core diameter range of the winding and unwinding shaft is 7.5 - 25 cm; the diameter range of the guiding roller is 6 - 20 cm; the diameter ranges of the tension adjusting roller and the tension detecting roller are 6 - 20 cm; further, the swing length corresponding to the movement of the tension adjusting roller, that is, the arc radius range of the arc-shaped through hole is 0.2 - 1 m; the central angle range corresponding to the arc of the arc-shaped through hole is 10° - 45°. Further, in this embodiment, the upper end of the wall panel extends forward to form a tension detecting roller installation portion, the tension detecting roller is arranged on the front side of the tension adjusting roller and the guiding roller, and is located between the guiding roller and the tension adjusting roller in the vertical direction; the tension sensor of the tension detecting roller is located below the roller body of the detecting roller.

[0020] Further, the outer diameters of the ends of the tension adjusting roller, the tension detecting roller, and / or the guiding roller gradually decrease in the outward direction to form conical roller heads.

[0021] Further, a plurality of hollow installation openings are provided on the lower side of the wall panel, and a plurality of fixed installation holes communicating with the surface of the bottom plate are provided on the lower wall surface of the hollow installation openings. Through the hollow installation openings, it is not only convenient to install and fix the wall panel, but also beneficial to the subsequent adjustment and maintenance of the winding and unwinding device.

[0022] Another object of the present utility model is to provide a winding and unwinding composite system, including the aforementioned winding and unwinding system and a composite device. Further, it includes the aforementioned winding and unwinding system and a composite device located downstream. Further, the composite device includes a plurality of composite rollers, and the second surface side opposite to the first surface side of the film roll passes against the plurality of composite rollers. Further still, the composite device further includes a driving roller downstream of the plurality of composite rollers for guiding out the already composite material.

Based on the product obtained by the aforementioned unwinding and rewinding system or the corresponding unwinding and rewinding composite system of the present application, the unwinding direction can be kept relatively stable before and after the unwinding and rewinding device sends out or stores, supplemented by deviation correction in the second direction, which can enable the film roll material to fully cooperate with the downstream material, and obtain high-quality products with corresponding flatness, sufficient processing and / or alignment, especially composite products. For the film roll with incompletely cured material on the surface to be compounded, based on the unwinding and rewinding system and the unwinding and rewinding composite system described in the present application, the surface material loss of the corresponding unwinding film roll is small, the corresponding composite material is closely and flatly attached, and the bubbles and gaps at the attachment interface are also reduced.

The second driving motor 1530 is located inside the installation opening, and the output end of the second motor abuts against the wall surface of the installation opening. The second driving motor 1530 is horizontally placed on the upper surface of the base 1440.

[0041] As Figure 6 , 9As shown, in this embodiment, the reeling and unwinding device 1100 includes a reeling and unwinding support 1110 and a reeling and unwinding shaft 1120. Furthermore, the reeling and unwinding support 1110 is provided with a tension adjustment roller 1130, a tension detection roller 1140, and at least one guide roller 1150. The relative positions of the tension adjustment roller 1130, the tension detection roller 1140, and the guide roller 1150 are arranged such that, as the film roll 2000 on the reeling and unwinding shaft 1120 passes through the tension adjustment roller 1130, the tension detection roller 1140, and the guide roller 1150, the first surface side 201 of the film roll 2000 only abuts against the surface of at most one roller of the tension adjustment roller 1130, the tension detection roller 1140, or the guide roller 1150.

Specifically, the film roll 2000 is a composite film roll, including a PET film layer / PP film layer / PI film layer and an adhesive layer, wherein the adhesive layer is arranged on the surface of the film layer; the first surface side 201 is the exposed adhesive side of the film layer. Furthermore, when the reeling and unreeling device 1100 of the present application is used in the unreeling process before compounding, the side of the film roll 2000 used for compounding with other materials only passes through one roller surface at most, which can avoid contact with the roller surface as much as possible, thereby reducing the loss of surface material before compounding and ensuring a certain degree of flatness; so that in the subsequent specific compounding, the downstream material can be flatly bonded, reducing bubbles and gaps between the bonding interfaces, etc., to significantly improve the quality of the finished composite material. Only a small number of rollers and a specific arrangement of rollers are required to reduce the loss of the exposed adhesive surface during the unreeling process, while ensuring the effects of unreeling tension control, etc.

[0047] Embodiment 2

[0048] This embodiment discloses a winding and unwinding system 1000, which is only different from Embodiment 1 in that it further includes a peeling component 1200. A release film layer is covered on the first surface side 201 of the film roll 2000; the unwinding device further includes a peeling component 1200, and the peeling component 1200 is arranged to peel the release film layer before the tension adjusting roller 1130, as Figure 9 shown. The peeling component 1200 is arranged to peel the release film layer before the film roll 2000 is unwound and passes through the tension adjusting roller 1130 and the tension detecting roller 1140.

[0049] The unwinding device is arranged in the unwinding direction, in sequence, with a guide roller 1150, a tension-adjusting roller 1130, and a tension-sensing roller 1140. In the roll-feeding direction, the stripping component 1200 is positioned between the tension-adjusting roller 1130 and the guide roller 1150, or before the guide roller 1150, or between the guide roller 1150 and the reel 1120. When the film roll 2000 has an adhesive layer on its surface, a release film is typically required to separate the outer adhesive layer from the inner film layer for convenient winding and storage. To facilitate direct lamination after unwinding, the release film must be removed beforehand. During this process, the release film generates a certain degree of interference. Positioning the stripping component 1200 before the tension-adjusting roller 1130 facilitates immediate adjustment to tension changes caused by the stripping process, ensuring smooth and even unwinding. The stripping component 1200 is particularly desirable before the tension-adjusting roller 1130 so that the tension can be promptly adjusted back to the desired tension.
