Description

Technical Field

[0001] The present invention relates to the technical field of conveying devices, and in particular to an anti-displacement winding device and a winding equipment for release paper. Background Art

[0002] After the release paper is produced, in some production processes, it is necessary to laminate the release paper on the adhesive layer to form a whole, and then wind the formed whole. When laminating the release paper on the adhesive layer, due to the deviation of the conveyance of the release paper in the previous station, there is a problem that the release paper and the adhesive layer are misaligned and cannot be aligned with each other during lamination. After lamination, the adhesive layer protrudes from the side of the release paper, affecting the subsequent production quality. Therefore, there is an urgent need for a winding device that can improve the conveyance accuracy of the release paper, thereby reducing the phenomenon of easy misalignment during the lamination of the release paper. Summary of the Invention

[0003] The purpose of the present invention is to provide an anti-displacement winding device and a winding equipment for release paper, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.

[0004] The solution of the present invention to solve its technical problems is as follows: The anti-displacement winding device for release paper includes, arranged in sequence along the conveyance direction of the release paper: a conveyance mechanism, which has a rotatable conveyance roller; an alignment mechanism, which includes a fixed frame, a driven shaft and a limiting component. A plurality of the driven shafts are arranged at intervals in the left-right direction on the fixed frame. A plurality of omnidirectional wheels are respectively arranged along the length direction of the driven shafts on the plurality of driven shafts. The limiting component is arranged on the fixed frame. Two limiting plates are arranged at intervals in the front-back direction inside the limiting component. Pressing rollers are respectively arranged on one side of the two limiting plates facing each other. The two pressing rollers are respectively located between the two driven shafts. The top sides of the two pressing rollers and the top sides of the plurality of omnidirectional wheels are all on the same horizontal plane. Upper pressing rollers are respectively arranged above the two pressing rollers on the two limiting plates; a conveying mechanism, which has a conveyable belt; a winding mechanism, which has a rotatable winding roller.

[0005] The technical solution has at least the following beneficial effects: During operation, the release paper reel can be directly installed on the conveying roller for unwinding, or the release paper can be led to the conveying roller by the previous station for unwinding. The release paper is led to the fixing frame, passes through multiple omnidirectional wheels on the driven shaft, and passes through between two limiting plates. The upper pressing roller and the lower pressing roller on the two limiting plates press and limit the side edges of the release paper, which is beneficial to straighten the side edges of the release paper, enhance the strength of the side edges of the release paper, and prevent the side edges of the release paper from being bent under the pressing force of the limiting plates. After passing through the two limiting plates, the release paper passes through the conveyor belt and is then relatively fixed on the winding roller. With the rotation of the winding roller, the winding of the release paper can be realized. When the release paper deviates before being led to the position adjustment mechanism, due to the clamping and conveying and limiting of the side edges of the release paper by the upper pressing roller, the lower pressing roller and the limiting plates, the accuracy of the release paper output from between the two limiting plates to the conveyor belt is effectively guaranteed. When the release paper reaches between the two limiting plates, it is always supported by the omnidirectional wheels, reducing the friction of the inclined conveying of the release paper. Thus, by adjusting the position and correcting the deviation during the conveying and winding of the release paper, the release paper can be accurately aligned with the peripheral structure during compounding, which is beneficial to preventing the phenomenon of final compounding misalignment caused by the misaligned conveying and winding of the release paper and the peripheral structure, and effectively improving the production quality.

[0006] As a further improvement of the above technical solution, the position adjustment mechanism further includes a slide rail, a slider and a swing frame. The slide rail is connected to the fixing frame. The slide rail is located on the side of the limiting component closer to the upstream of the release paper conveyance and between the two driven shafts. The slider is slidably connected to the slide rail in the front-back direction. The swing frame is rotatably connected to the slider about an axis in the up-down direction. Two side plates are arranged at intervals in the front-back direction inside the swing frame, and a limiting area is formed between the two side plates. The release paper first passes through the limiting area formed by the two side plates and then passes through the two limiting plates. The swing frame is connected to the slide rail through the slider and has the freedom of movement in the front-back direction. The swing frame itself is rotatably connected to the slider and has the freedom of rotation about an axis in the up-down direction. When the conveyed release paper deviates, the two side edges of the release paper abut against the two side plates, driving the two side plates to slide and rotate to adapt to the inclined deviation of the release paper. When the deviation of the release paper is too large, after the two sides of the release paper are subjected to the pressure of the side plates, the release paper arches from both sides to the middle. Thus, the inclined transition of the release paper is limited by the side plates, which is beneficial to further improving the effect of limiting the position of the release paper, and the swing frame itself can be adjusted in position without damaging the release paper itself.

[0007] As a further improvement of the above technical solution, lower pinch rollers are respectively arranged on one side of the two side plates facing each other. The top sides of the two lower pinch rollers and the top sides of the multiple omnidirectional wheels are respectively located on the same horizontal plane. Upper pinch rollers are respectively arranged at positions of the two side plates above the two lower pinch rollers. The upper pinch rollers and the lower pinch rollers for limiting the side edges of the release paper are provided on the side plates. The side edges of the release paper are pressed and limited by the upper pinch rollers and the lower pinch rollers, which is beneficial to preventing the side edges of the release paper from being folded when the pressure from the side plates is too large, and improving the stability of the release paper conveyance.

[0008] As a further improvement of the above technical solution, a first adjusting screw rod is arranged on the swing frame, and the two side plates are respectively arranged on the first adjusting screw rod. The first adjusting screw rod can drive the two side plates to approach or move away from each other. The first adjusting screw rod can adjust the distance between the two side plates, so as to adapt to the widths of different release papers and improve the use flexibility.

[0009] As a further improvement of the above technical solution, the limiting component includes a limiting frame connected to the fixed frame. A second adjusting screw rod is arranged on the limiting frame, and the two limiting plates are respectively arranged on the second adjusting screw rod. The second adjusting screw rod can drive the two limiting plates to approach or move away from each other. Similarly, the second adjusting screw rod can adjust the distance between the two limiting plates, so as to adapt to the widths of different release papers and further improve the use flexibility.

[0010] As a further improvement of the above technical solution, the present invention further includes a flattening roller, and the flattening roller is located between the position adjusting mechanism and the conveying mechanism. After the release paper passes through the two limiting plates and is output, the release paper passes through the flattening roller, and the flattening roller unfolds the release paper to both sides, further improving the effect of conveying, unfolding and winding the release paper.

[0011] As a further improvement of the above technical solution, guiding sections are respectively formed on one side of the two limiting plates close to the conveying roller, and the distance between the two guiding sections gradually increases along the direction close to the conveying roller. When the inclined release paper enters between the two limiting plates, it first passes between the two guiding sections. At this time, the two guiding sections form a narrowing structure for guiding the release paper towards the limiting plates, thereby improving the smoothness of the release paper entering between the two limiting plates and being beneficial to preventing the phenomenon that the release paper is scratched by the side edges of the limiting plates when entering between the two limiting plates.

[0012] As a further improvement of the above technical solution, the conveyor belt is formed with an inclined section and a horizontal section connected to each other, and the inclined section extends obliquely upward in a direction away from the fixed frame. When the release paper is fed onto the conveyor belt, it first passes through the inclined section to guide the release paper so that the release paper rises, and then passes through the horizontal section and is led out from the horizontal section. In this way, the release paper can be compounded with the externally provided adhesive layer on the horizontal section, which is convenient for processing and compounding the release paper before winding.

[0013] As a further improvement of the above technical solution, the winding mechanism includes a winding motor, and the winding motor is drivingly connected to the winding roller. The winding motor provides power to the winding roller, thereby driving the winding roller to rotate and winding the release paper.

[0014] A winding device includes the above-mentioned release paper anti-displacement winding device, and two sets of the conveying mechanism, the position adjusting mechanism and the conveying mechanism are symmetrically arranged in the up-down direction, and a pressing gap is formed between the two conveyor belts.

[0015] This technical solution has at least the following beneficial effects: During operation, the release paper can be fed through one set of the conveying mechanism, the position adjusting mechanism and the conveying mechanism, while the adhesive layer can be fed through the other set of the conveying mechanism, the position adjusting mechanism and the conveying mechanism. Then, the release paper and the adhesive layer are compounded into one on the two conveying mechanisms and then led to the winding roller together for winding. During this process, the positions of the release paper and the adhesive layer can be accurately fed and wound, which is beneficial to preventing the phenomenon of displacement between the release paper and the adhesive layer in subsequent production, thereby improving the production quality.

Detailed implementation mode

[0021] The following will clearly and completely describe the concept, specific structure and technical effects generated by the present invention in combination with the embodiments and the attached drawings, so as to fully understand the purpose, features and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present invention. In addition, all the connection relationships mentioned in the text do not refer only to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. Each technical feature in the present invention can be combined interactively on the premise of not conflicting with each other.

[0022] Refer to Figure 1 And Figure 2 , the anti-displacement winding device for release paper, including, arranged in sequence along the conveying direction of the release paper: a conveying mechanism, which has a rotatable conveying roller 100, and the driving roller can be a driven roller shaft, or a roller shaft driven by an independent motor to rotate; an adjusting mechanism, which includes a fixing frame 210, a driven shaft and a limiting component, the driven shaft is arranged at intervals in the left-right direction on the fixing frame 210, a plurality of omnidirectional wheels 220 are respectively arranged along the length direction of the driven shaft on the plurality of driven shafts, the limiting component is arranged on the fixing frame 210, two limiting plates 230 are arranged at intervals in the front-back direction in the limiting component, lower pressing rollers are respectively arranged on one side of the two limiting plates 230 facing each other, the two lower pressing rollers are respectively located between the two driven shafts, the top sides of the two lower pressing rollers and the top sides of the plurality of omnidirectional wheels 220 are all on the same horizontal plane, and upper pressing rollers 240 are respectively arranged above the two lower pressing rollers on the two limiting plates 230; a conveying mechanism, which has a rotatable conveyor belt; a winding mechanism, which has a rotatable winding roller 310.

[0023] In this release paper anti-displacement winding device, during operation, the release paper reel can be directly installed on the conveying roller 100, and unwinding can be carried out from the conveying roller 100. Or the release paper can be led to the conveying roller 100 by the previous station for unwinding. The release paper is led to the fixed frame 210, passes through a plurality of omnidirectional wheels 220 on the driven shaft, and passes through between two limiting plates 230. The upper pressing roller 240 and the lower pressing roller on the two limiting plates 230 tightly limit the side edges of the release paper, which is beneficial to straighten the side edges of the release paper, enhance the strength of the side edges of the release paper, and prevent the side edges of the release paper from being bent under the pressing force of the limiting plates 230. After passing through the two limiting plates 230, the release paper passes through the conveyor belt and is then relatively fixed on the winding roller 310. With the rotation of the winding roller 310, the winding of the release paper can be realized. When the release paper is offset before being led to the position adjustment mechanism, due to the clamping and limiting of the side edges of the release paper by the upper pressing roller 240, the lower pressing roller and the limiting plates 230, the accuracy of the release paper output from between the two limiting plates 230 to the conveyor belt is effectively guaranteed. And when the release paper reaches between the two limiting plates 230, it is always supported by the omnidirectional wheels 220, reducing the friction of the inclined conveying of the release paper. Thus, by adjusting the position and correcting the deviation during the conveying and winding of the release paper, the release paper can be accurately aligned with the external structure during compounding, which is beneficial to preventing the phenomenon of final compounding misalignment caused by the misaligned conveying and winding of the release paper and the external structure, and effectively improving the production quality.

[0024] Since the two limit plates 230 are relatively fixedly arranged on the fixing frame 210, when the release paper is tilted and offset, in order to better guide the release paper between the two limit plates 230, in this embodiment, the position adjusting mechanism further includes a slide rail 251, a slider and a swing frame 252. The slide rail 251 is connected to the fixing frame 210. The slide rail 251 is located on the side of the limit component closer to the upstream of the release paper conveyance. The slide rail 251 is located between the two driven shafts. The slider is slidably connected to the slide rail 251 in the front-rear direction. The swing frame 252 is rotatably connected to the slider about an axis in the up-down direction. Two side plates 253 are arranged at intervals in the front-rear direction in the swing frame 252. A limit area is formed between the two side plates 253. The release paper first passes through the limit area formed by the two side plates 253 and then passes through the two limit plates 230. The swing frame 252, through the connection between the slider and the slide rail 251, has the freedom of movement in the front-rear direction, and the swing frame 252 itself is rotatably connected to the slider and has the freedom of rotation about an axis in the up-down direction. When the conveyed release paper is offset, the two sides of the release paper abut against the two side plates 253, driving the two side plates 253 to slide and rotate to adapt to the tilt and offset of the release paper. When the offset of the release paper is too large, after the two sides of the release paper are subjected to the pressure of the side plates 253, the release paper arches from both sides to the middle. In this way, the side plates 253 are used to limit the tilt transition of the release paper, which is beneficial to further improve the effect of limiting the position of the release paper, and the swing frame 252 itself can be adjusted in position without damaging the release paper itself.

[0025] In order to better maintain the flatness of the side of the release paper, in this embodiment, lower pinch rollers are respectively arranged on one side of the two side plates 253 facing each other. The top sides of the two lower pinch rollers and the top sides of the multiple omnidirectional wheels 220 are respectively located on the same horizontal plane. Upper pinch rollers 254 are respectively arranged at positions of the two side plates 253 above the two lower pinch rollers. The upper pinch rollers 254 and the lower pinch rollers for limiting the side edges of the release paper are provided on the side plates 253. Using the upper pinch rollers 254 and the lower pinch rollers to tightly limit the side edges of the release paper is beneficial to preventing the phenomenon of the side edges of the release paper from folding when the pressure of the side plates 253 is too large, and improving the stability of the conveyance of the release paper.

[0026] In some embodiments, a first adjusting lead screw 255 is provided on the swing frame 252, and two side plates 253 are respectively arranged on the first adjusting lead screw 255. The first adjusting lead screw 255 can drive the two side plates 253 to approach or move away from each other. The first adjusting lead screw 255 can adjust the distance between the two side plates 253, so as to adapt to the widths of different release papers and improve the flexibility of use. In practical applications, both the screw pair and the nut pair of the first adjusting lead screw 255 can be installed inside the swing frame 252, so as to reduce the protrusion of the transmission structure and prevent interference with the movement of the release paper. Moreover, the release paper itself is tightly clamped and limited in the vertical direction by the upper pinch roller 254 and the lower pinch roller, and will not contact the swing frame 252 itself, effectively avoiding the problem that the release paper is worn and damaged due to interference by the swing frame 252 or the first adjusting lead screw 255.

[0027] Similarly, the limiting assembly includes a limiting frame connected to the fixed frame 210. A second adjusting lead screw 260 is provided on the limiting frame, and two limiting plates 230 are respectively arranged on the second adjusting lead screw 260. The second adjusting lead screw 260 can drive the two limiting plates 230 to approach or move away from each other. Similarly, the second adjusting lead screw 260 can adjust the distance between the two limiting plates 230, so as to adapt to the widths of different release papers and further improve the flexibility of use. Since the upper pressing roller 240 and the lower pressing roller tightly clamp and limit the release paper, the release paper will not contact the second adjusting lead screw 260 or the limiting frame itself.

[0028] When the deviation angle of the release paper is relatively large, after the release paper enters between the two limiting plates 230, the middle part of the release paper will be lifted, so as to adapt to the limiting adjustment of the position of the release paper by the two limiting plates 230. Therefore, in order to ensure the flatness of the overall release paper after output, the present invention further includes a flattening roller 400, and the flattening roller 400 is located between the position adjusting mechanism and the conveying mechanism. When the release paper passes through the two limiting plates 230 and is output, the release paper passes through the flattening roller 400, and the flattening roller 400 unfolds the release paper to both sides, further improving the effect of conveying, unfolding and winding the release paper.

[0029] In order to smoothly transition the release paper between the two limiting plates 230, in this embodiment, guiding sections 231 are respectively formed on one side of the two limiting plates 230 close to the conveying roller 100, and the distance between the two guiding sections 231 gradually increases along the direction close to the conveying roller 100. When the inclined release paper enters between the two limiting plates 230, it first passes between the two guiding sections 231. At this time, the two guiding sections 231 form a narrowing structure for guiding the release paper towards the limiting plates 230, thereby improving the smoothness of the release paper entering between the two limiting plates 230 and facilitating the prevention of the phenomenon that the release paper is scratched on the side of the limiting plates 230 when entering between the two limiting plates 230.

[0030] The conveying mechanism may be a belt conveyor, thereby forming a rotating conveyor belt. Specifically, the conveyor belt is formed with an inclined section 510 and a horizontal section 520 connected to each other, and the inclined section 510 extends upwardly in an inclined direction away from the fixing frame 210. When the release paper is led to the conveyor belt, it first passes through the inclined section 510 to guide the release paper so that the release paper rises, and then passes through the horizontal section 520 and is led outward from the horizontal section 520, so that the release paper can be compounded with the adhesive layer of the external device on the horizontal section 520, which is convenient for processing and compounding the release paper before winding.

[0031] The winding mechanism has a driving source that can drive the winding roller 310 to rotate. Specifically, the winding mechanism includes a winding motor 320, and the winding motor 320 is connected to the winding roller 310. The winding motor 320 provides power to the winding roller 310, thereby driving the winding roller 310 to rotate and winding the release paper.

[0032] like Figure 3 As shown, a winding device includes the above-mentioned release paper anti-misalignment winding device, and two of the transmission mechanism, the adjustment mechanism and the conveying mechanism are symmetrically arranged in the up and down directions, and a pressing gap is formed between the two conveying belts.

[0033] During operation, the release paper can be fed through a conveying mechanism, a positioning mechanism and a transport mechanism, while the adhesive layer can be fed through another conveying mechanism, a positioning mechanism and a transport mechanism, and then the release paper and the adhesive layer are compounded into one on the two transport mechanisms, and then fed together to the winding roller 310 for winding. During this process, the positions of the release paper and the adhesive layer can be accurately fed out and wound, which is beneficial to prevent the release paper and the adhesive layer from being misaligned in subsequent production, thereby improving production quality.

[0034] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
