Description

Technical Field

[0001] This utility model relates to the field of film winding technology, and in particular to a planar winding device. Background Technology

[0002] In the production of environmentally friendly laminated membrane materials, one process involves slitting the product. Currently, existing inspection and slitting equipment faces numerous challenges in slitting products such as awnings, bags, air-supported membranes, mesh-lined waders, and adjustable support pools.

[0003] The gap between the rotating rollers of the existing winding device is fixed and cannot be adjusted flexibly according to the characteristics of different products. As a result, when winding different products, the ideal winding effect cannot be achieved. Problems such as loose products and wrinkles are prone to occur during the winding process, which seriously affects production efficiency and product quality. Utility Model Content

[0004] Therefore, a planar winding device is needed to solve the technical problem that the gap between the rotating rollers of the existing winding device is fixed and cannot be adjusted flexibly according to the characteristics of different products. This results in the inability to achieve the ideal winding effect when winding different products, and problems such as loose products and wrinkles are prone to occur during the winding process, which seriously affects production efficiency and product quality.

[0005] To achieve the above objectives, this utility model provides a planar winding device, comprising:

[0006] frame;

[0007] A rotating mechanism is mounted on a frame. The rotating mechanism includes a power unit, two or more rotating rollers arranged parallel to the length direction of the frame, two or more mounting seats, and two or more first fasteners. The two or more rotating rollers are spaced apart along the width direction of the frame, and each rotating roller has a mounting seat on both sides. Each mounting seat has a first oblong hole parallel to the width direction of the frame at its four corners. The first fasteners are used to mount the mounting seats on the frame through the first oblong holes to adjust the position of each rotating roller along the width direction of the frame.

[0008] The unit has a slitting station between two adjacent rotating rollers, which is used to place the slitting roller; the power unit is connected to two or more rotating rollers and drives the two or more rotating rollers to rotate.

[0009] Unlike existing technologies, the above technical solution is equipped with a mounting base, and the mounting base has first oblong holes at the four corners. This allows the gap between the rotating rollers along the width of the frame to be adjusted according to different slitting materials by cooperating with the first oblong holes and the first fasteners. This effectively avoids problems such as indentations, wrinkles, and loosening caused by improper gaps, ensuring that the slitting materials are tightly and flat, and improving production efficiency and the quality of the slitting materials.

[0010] As one embodiment of this utility model, the middle part of the mounting base has a second oblong hole at the upper and lower ends of the rotating roller, which is parallel to the height direction of the frame. The rotating mechanism also includes two or more second fasteners. The second fasteners install the mounting base on the frame through the second oblong holes to adjust the position of each rotating roller along the height direction of the frame.

[0011] Thus, by setting the second oblong hole and cooperating with the second fastener, the position of each rotating roller along the height direction of the frame can be adjusted, so that the rotating roller can adapt to the thickness variation of the slitting material.

[0012] As one embodiment of this utility model, the rotating mechanism also includes an unfolding roller arranged parallel to the length direction of the frame. The two sides of the unfolding roller are installed at the feed inlet of the frame, and the rolled material enters the rotating roller through the unfolding roller.

[0013] In this way, before entering the rotating roller, the slitting material first passes around the arc-shaped surface of the unwinding roller. The curvature of the roller releases the internal stress of the material, eliminating natural curling and slight wrinkles generated during transportation or unwinding, thus ensuring the flatness of the slitting material from the source.

[0014] As one embodiment of this utility model, the planar winding device further includes a pressing mechanism. The pressing mechanism includes a pressing roller arranged parallel to the length direction of the frame, two cylinders arranged along the width direction of the frame, and two swing rods. The two sides of the pressing roller are mounted on the frame. Each side of the pressing roller corresponds to a cylinder and a swing rod. The cylinders are mounted on the inner side of the frame. The output end of the cylinder is connected to the pressing roller through the swing rod. The cylinder drives the pressing roller to rotate so that the pressing roller presses the slitting material.

[0015] In this way, the pressure roller can press down the slit material during the initial winding to prevent the fabric from slipping and provide traction. It can also press down the slit material during the rewinding process to prevent it from slipping off when the slit material is cut.

[0016] As one embodiment of this utility model, the planar winding device further includes an adjustment mechanism. The adjustment mechanism includes two slide rods arranged parallel to the length direction of the frame, two adjustment brackets, and two or more adjustment baffles. The two slide rods are installed on the frame, one slide rod is located at the feed inlet of the frame, and the other slide rod is located at the discharge outlet of the frame. The two ends of the adjustment brackets are sleeved outside the two slide rods and slide outside the slide rods along the length direction of the frame. Each adjustment bracket is equipped with at least one adjustment baffle. The two or more adjustment baffles cooperate to limit the size of the winding material along the length direction of the frame.

[0017] In this way, the two adjusting brackets can slide on the two slide bars along the length of the frame, so that the adjusting baffles installed on the two adjusting brackets can be flexibly adjusted in distance, accurately limiting the length of the slitting material, effectively preventing the lateral displacement of the slitting material, ensuring the dimensional accuracy of the slitting material, reducing the scrap rate, and improving production efficiency.

[0018] As one embodiment of this utility model, four adjustment baffles are provided, and two adjustment baffles are installed on each adjustment bracket.

[0019] Thus, the use of four adjusting baffles can better prevent lateral displacement of the split material.

[0020] In one embodiment of this utility model, the bottom of the adjusting baffle is pointed, and the two ends of the pointed end are arc-shaped to avoid the rotating roller.

[0021] Thus, the bottom of the adjusting baffle is pointed, and arcs are set at both ends of the pointed end to avoid interfering with the rotation of the rotating roller.

[0022] As one embodiment of this utility model, the frame includes a base plate and two side plates, with a side plate installed on each side of the base plate.

[0023] The power assembly is installed on one of the side plates. The power assembly includes a drive motor, a tension sprocket, and two or more rotating sprockets. The output end of the drive motor is connected to the tension sprocket, and the tension sprocket is connected to two or more rotating sprockets. A rotating sprocket is installed on one side of each rotating roller.

[0024] In this way, the tension sprocket and the cooperation of two or more rotating sprockets achieve stable transmission and efficient operation of winding power, ensuring the continuity and reliability of winding operations for products of different specifications, reducing equipment downtime due to malfunctions, and improving production efficiency.

[0025] As one embodiment of this utility model, the frame also includes a protective box, which is installed outside one of the side panels and has an inspection door.

[0026] Thus, the exposed power components can be protected by a protective enclosure. Furthermore, the inclusion of an access door facilitates subsequent maintenance.

[0027] In one embodiment of this utility model, three rotating rollers are provided, six mounting bases are provided, and twenty-four first fasteners are provided.

[0028] Therefore, it is preferable to have three rotating rollers, with two slitting stations, thereby improving slitting efficiency.

[0029] The above description of the utility model is merely an overview of the technical solution of this application. In order to enable those skilled in the art to better understand the technical solution of this application and to implement it based on the description and drawings, and to make the above-mentioned objectives and other objectives, features and advantages of this application easier to understand, the following description is provided in conjunction with the specific embodiments and drawings of this application.

[0049] The gap between the rotating rollers of the existing winding device is fixed and cannot be adjusted flexibly according to the characteristics of different products. As a result, when winding different products, the ideal winding effect cannot be achieved. Problems such as loose products and wrinkles are prone to occur during the winding process, which seriously affects production efficiency and product quality.

[0050] In view of this, this application provides a planar winding device 100, including a frame 1 and a rotating mechanism 2. The rotating mechanism 2 is mounted on the frame 1 and includes a power component 21, two or more rotating rollers 22 arranged parallel to the length direction X of the frame, two or more mounting seats 23, and two or more first fasteners 24. The two or more rotating rollers 22 are spaced apart along the width direction Y of the frame, and each rotating roller 22 has a mounting seat 23 on both sides. The four corners of the mounting seat 23 are provided with first oblong holes 231 parallel to the width direction Y of the frame. The first fasteners 24 install the mounting seats 23 on the frame 1 through the first oblong holes 231 to adjust the position of each rotating roller 22 along the width direction Y of the frame. There is a slitting station 25 between two adjacent rotating rollers 22, which is used to place the slitting roller. The power component 21 is connected to the two or more rotating rollers 22 and drives the two or more rotating rollers 22 to rotate.

[0051] According to some embodiments of this application, please refer to Figures 1 to 6 This embodiment relates to a planar winding device 100, including a frame 1 and a rotating mechanism 2. The rotating mechanism 2 is mounted on the frame 1 and includes a power component 21, two or more rotating rollers 22 arranged parallel to the length direction X of the frame, two or more mounting seats 23, and two or more first fasteners 24. The two or more rotating rollers 22 are spaced apart along the width direction Y of the frame, and each rotating roller 22 has a mounting seat 23 on both sides. The four corners of the mounting seat 23 are provided with first oblong holes 231 parallel to the width direction Y of the frame. The first fasteners 24 are used to mount the mounting seats 23 on the frame 1 through the first oblong holes 231 to adjust the position of each rotating roller 22 along the width direction Y of the frame. There is a slitting station 25 between two adjacent rotating rollers 22, which is used to place the slitting roller. The power component 21 is connected to the two or more rotating rollers 22 and drives the two or more rotating rollers 22 to rotate.

[0052] The flat winding device 100 is used for slitting environmentally friendly laminating film material, that is, the slitting material 200 can be environmentally friendly laminating film material.

[0053] In actual use, loosening the first fastener 24 allows the mounting base 23 to slide along the width direction Y of the frame, thereby adjusting the spacing of the rotating rollers 22. The first fastener 24 can be a bolt, screw, stud, etc.

[0054] Unlike existing technologies, the above technical solution is equipped with a mounting base 23, and first oblong holes 231 are provided at the four corners of the mounting base 23. Thus, according to different slitting materials 200, the gap between the rotating roller 22 and the rotating roller 22 along the width direction Y of the frame can be adjusted by the cooperation of the first oblong holes 231 and the first fastener 24. This effectively avoids problems such as indentations, wrinkles and looseness caused by improper gaps, ensures that the slitting material 200 is tightly and flatly slitting, and improves production efficiency and the quality of the slitting material 200.

[0055] like Figure 3 As shown, the middle part of the mounting base 23 has a second oblong hole 232 that is parallel to the height direction Z of the frame at both the upper and lower ends of the rotating roller 22. The rotating mechanism 2 also includes two or more second fasteners 26. The second fasteners 26 install the mounting base 23 on the frame 1 through the second oblong hole 232 to adjust the position of each rotating roller 22 along the height direction Z of the frame.

[0056] In actual use, loosening the second fastener 26 allows adjustment of the position of the rotating roller 22 along the height direction Z of the frame. The second fastener 26 can be a bolt, screw, stud, etc.

[0057] Thus, by setting the second waist-shaped hole 232 to cooperate with the second fastener 26, the position of each rotating roller 22 along the height direction Z of the frame can be adjusted, so that the rotating roller 22 can adapt to the thickness variation of the slitting material 200.

[0058] like Figure 6 As shown, the rotating mechanism 2 also includes an unfolding roller 27 arranged parallel to the length direction X of the frame. The two sides of the unfolding roller 27 are installed at the feed inlet of the frame 1, and the rolled material 200 enters the rotating roller 22 through the unfolding roller 27.

[0059] The unfolding roller 27 is located below the rotating roller 22, and the slitting material 200 enters the rotating roller 22 through the unfolding roller 27.

[0060] Thus, before entering the rotating roller 22, the slitting material 200 first passes around the arc-shaped surface of the unwinding roller 27, releasing the internal stress of the material through the curvature of the roller body, eliminating natural curling and slight wrinkles generated during transportation or unwinding, and ensuring the flatness of the slitting material 200 from the source.

[0061] like Figure 4 and Figure 6As shown, the planar winding device 100 also includes a pressing mechanism 3. The pressing mechanism 3 includes a pressing roller 31 arranged parallel to the length direction X of the frame, two cylinders 32 arranged along the width direction Y of the frame, and two swing rods 33. The two sides of the pressing roller 31 are mounted on the frame 1. Each side of the pressing roller 31 corresponds to a cylinder 32 and a swing rod 33. The cylinders 32 are mounted on the inner side of the frame 1. The output end of the cylinders 32 is connected to the pressing roller 31 through the swing rods 33. The cylinders 32 drive the pressing roller 31 to rotate so that the pressing roller 31 presses the slitting material 200.

[0062] Optionally, the pressure roller 31 is located between the unfolding roller 27 and the rotating roller 22. The cylinder 32 controls the pressure roller 31 to press down onto the rotating roller 22. In actual use, the slitting roller is first placed on the slitting station 25. Then, the pressure roller 31 can press down on the slitting material 200 at the beginning of the winding process, providing traction. The slitting material 200 enters from the unfolding roller 27 and enters the rotating roller 22, and then is slid onto the slitting roller via the rotating roller 22. Finally, the slitting material 200 is pressed down again after slitting to prevent it from slipping when cutting.

[0063] Thus, the pressure roller 31 can press the slit material 200 during the initial winding to prevent the fabric from slipping and provide traction. It can also press the slit material 200 during the rewinding process to prevent it from slipping off when cutting it.

[0064] like Figure 5 and Figure 6 As shown, the planar winding device 100 also includes an adjustment mechanism 4. The adjustment mechanism 4 includes two slide rods 41 arranged parallel to the length direction X of the frame, two adjustment brackets 42, and two or more adjustment baffles 43. The two slide rods 41 are installed on the frame 1, one slide rod 41 is located at the feed port of the frame 1, and the other slide rod 41 is located at the discharge port of the frame 1. The two ends of the adjustment brackets 42 are sleeved on the two slide rods 41 and slide outside the slide rods 41 along the length direction X of the frame. Each adjustment bracket 42 is equipped with at least one adjustment baffle 43. The two or more adjustment baffles 43 cooperate to limit the size of the winding material 200 along the length direction X of the frame.

[0065] The adjusting bracket 42 is L-shaped. The height of the slide rod 41 near the feed inlet of the frame 1 along the height direction Z is higher than that of the slide rod 41 near the discharge outlet of the frame 1. The front and rear ends of the slide rod 41 can slide on the slide rod 41, and the sliding of the slide rod 41 drives the adjusting baffle 43 to move accordingly. By sliding the two slide rods 41, the distance between the adjusting baffles 43 on the two slide rods 41 along the length direction X of the frame corresponds to the size of the slitting material 200. After the position is determined, the adjusting bracket 42 can be fixed to the corresponding position of the slide rod 41 with bolts to lock the position. The adjusting baffle 43 can be fixed to the inner side of the adjusting bracket 42 with bolts, so that the adjusting baffles 43 on the two adjusting brackets 42 are arranged opposite each other.

[0066] In this way, the two adjusting brackets 42 can slide along the length direction X of the frame on the two slide bars 41, so that the adjusting baffles 43 installed on the two adjusting brackets 42 can flexibly adjust the spacing, accurately limit the length of the slitting material 200, effectively prevent the lateral deviation of the slitting material 200, ensure the dimensional accuracy of the slitting material 200, reduce the scrap rate, and improve production efficiency.

[0067] like Figure 1 , Figure 2 and Figure 5 As shown, there are four adjusting baffles 43, and two adjusting baffles 43 are installed on each adjusting bracket 42.

[0068] Thus, the four adjusting baffles 43 work together to better prevent the lateral displacement of the split material 200.

[0069] like Figure 5 and Figure 6 As shown, the bottom of the adjusting baffle 43 is pointed, and the two ends of the pointed end are arc-shaped to avoid the rotating roller 22.

[0070] Thus, the bottom of the adjusting baffle 43 is pointed, and arcs are set at both ends of the pointed end to avoid interfering with the rotation of the rotating roller 22.

[0071] like Figure 6 As shown, the frame 1 includes a base plate 11 and two side plates 12. One side plate 12 is installed on each side of the base plate 11. The power assembly 21 is installed on one of the side plates 12. The power assembly 21 includes a drive motor 211, a tension sprocket 212 and two or more rotating sprockets 213. The output end of the drive motor 211 is connected to the tension sprocket 212. The tension sprocket 212 is connected to the two or more rotating sprockets 213. A rotating sprocket 213 is installed on one side of each rotating roller 22.

[0072] The frame 1 base plate 11 includes a base plate 11 and two side plates 12. The base plate 11 and the two side plates 12 are welded together to provide overall support.

[0073] The tension sprocket 212 is located below the rotating roller 22. The drive motor 211 drives the tension sprocket 212 and two or more rotating sprockets 213 via chain drive (each rotating roller 22 corresponds to a set of sprockets, and each set includes two rotating sprockets 213; one rotating sprocket 213 on one rotating roller 22 is connected to the tension sprocket 212 via chain drive, and the other rotating sprocket 213 is connected to the rotating sprockets 213 of other rotating rollers 22 via chain drive), achieving synchronous rotation. The tension sprocket 212 can move along the width Y direction of the frame to tension the chain.

[0074] In this way, the stable transmission and efficient operation of winding power are achieved through the cooperation of tension sprocket 212 and two or more rotating sprockets 213, ensuring the continuity and reliability of winding operations for products of different specifications, reducing equipment downtime due to malfunctions, and improving production efficiency.

[0075] like Figure 2 As shown, the frame 1 also includes a protective box 13, which is installed outside one of the side panels 12 and has an inspection door.

[0076] Thus, the exposed power components 21 can be protected by the protective enclosure 13. In addition, the installation of an access door facilitates subsequent maintenance.

[0077] like Figures 1 to 3 As shown, there are three rotating rollers 22, six mounting bases 23, and twenty-four first fasteners 24.

[0078] Therefore, it is preferable to have three rotating rollers 22, and the three rotating rollers 22 have two slitting stations 25, thereby improving the slitting efficiency.

[0079] In this embodiment, the power mechanism or power unit includes, but is not limited to, engines, motors, pneumatic tools, hydraulic pumps, etc. The power unit also includes direct power sources and indirect power sources. Direct power sources are those that can provide their own power, such as engines and motors, while indirect power sources include cylinders and hydraulic cylinders. The power mechanism or power unit can drive the linear reciprocating motion of the actuator through gear and rack engagement, slider and groove engagement, lead screw and nut engagement, etc.

[0080] In this embodiment, the transmission mechanism or transmission unit includes a speed reducer, gearbox, worm gear mechanism, linkage mechanism, compound mechanism, etc. The transmission mechanism or transmission unit is used to transmit power from the power mechanism or power unit to the actuator or actuator.

[0081] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of patent protection for this utility model.
