Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and in particular to a cutting mechanism, a winding device and a coating equipment. Background Technology

[0002] During the process of coating foil with different coating processes and then winding it into a roll, since there are two different requirements for the unwinding direction of the roll, namely the top and the bottom, a cutting mechanism is needed to cut the foil on the top or bottom of the roll to form a roll with the unwinding direction being either the top or the bottom.

[0003] However, the current cutting mechanism can only meet one type of material roll cutting method, that is, a cutting mechanism can only cut foil on one side of the material roll, either on the top or bottom side. When switching the cutting side of the material roll, it is necessary to disassemble and replace it with a new cutting mechanism that matches it, and then reassemble and debug it. The operation is cumbersome, time-consuming and labor-intensive, resulting in low foil winding efficiency.

[0004] To address the above problems, there is an urgent need for a cutting mechanism, a winding device, and a coating equipment. Utility Model Content

[0005] The purpose of this invention is to provide a cutting mechanism, a winding device, and a coating equipment that can selectively cut foil on the upper and lower sides of the roll according to the specific unwinding direction requirements of the roll, thereby improving the winding efficiency of the foil. The structure is simple and compact, occupies less space, and has a lower production cost.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0010] The first cutting assembly is connected between the two swing arms and is used to swing to the underside of the roll to cut the foil.

[0011] The second cutter assembly is connected between the two swing arms and spaced apart from and arranged side by side with the first cutter assembly. The second cutter assembly is used to swing to the upper side of the roll to cut the foil.

[0012] Alternatively, along the Z-axis, the axis of rotation is lower than the highest point of the coil formed by winding and higher than the lowest point of the coil.

[0013] As an optional embodiment, the structure of the second cutter assembly is the same as that of the first cutter assembly; a bracket is connected to the end of the swing arm away from the rotation axis; the first cutter assembly includes:

[0014] A cutter is arranged parallel to the rotating shaft, and the two opposite ends of the cutter are respectively rotatably connected to the two supports. The cutter is used to rotatably cut the foil.

[0015] Pressure rollers are arranged parallel to and spaced apart on one side of the cutter. The opposite ends of the pressure rollers are movably connected to the two supports, and the pressure rollers can press the foil material closer to or away from it.

[0016] As an optional feature, the cutting edge of the cutter has a long, serrated structure.

[0017] As an optional solution, the first cutting blade assembly further includes:

[0018] The first driving component has its fixed end located on the inner side of the swing arm;

[0019] The connecting rod, wherein the driving end of the first driving member is drivingly connected to one end of the connecting rod;

[0020] A connector is provided, wherein the other end of the connecting rod is hinged to the connector, and the connector is rotatably connected to the inner side of the bracket and connected to one end of the cutter. The first driving member is used to pull the connecting rod and the connector to move, thereby driving the cutter to rotate along its axial direction.

[0021] As an optional solution, the first cutting blade assembly further includes:

[0022] The second driving member has its fixed end located on the swing arm or the bracket, and its driving end is connected to the pressure roller. The second driving member is used to drive the pressure roller to press or move away from the foil.

[0023] As an optional solution, the first cutting blade assembly further includes:

[0024] A sensor is disposed on the side of the pressure roller near the foil material. The sensor is used to sense the outer diameter of the roll and is communicatively connected to the first drive and the second drive.

[0025] As an optional solution, at least one reinforcing shaft is connected between the two swing arms.

[0026] A winding device, comprising:

[0027] Framework;

[0028] A take-up roller is rotatably disposed on the frame body along its axial direction. The take-up roller is used to rotate and take up the foil to form the roll.

[0029] As described above, in the cutting mechanism, the rotating shaft is rotatably mounted on the frame body along its axial direction, and the rotating shaft is located on one side upstream of the take-up roller;

[0035] The winding device described above is located downstream of the drying device.

[0036] The beneficial effects of this utility model are as follows:

[0037] The cutting mechanism of this invention uses a rotating shaft positioned upstream of the coil to wind the foil around the shaft and form a coil. Swing arms are positioned at opposite ends of the rotating shaft along its axial direction, with a first cutting assembly and a second cutting assembly positioned between the two parallel swing arms. The swing arms can swing around the axis of the rotating shaft, causing the first and second cutting assemblies to swing synchronously. The first cutting assembly swings to the lower side of the coil to cut the foil, while the second cutting assembly swings to the upper side to cut the foil. By using these two mutually cooperating cutting assemblies, the foil can be selectively cut on the upper and lower sides of the coil according to the specific unwinding direction requirements, eliminating the need to disassemble and replace the cutting mechanism with a new one and reassemble it for adjustment, thus simplifying the foil cutting operation. Convenient, time-saving, and labor-saving, thus improving the winding efficiency of foil materials; at the same time, the integration of the first and second cutting assemblies between the two swing arms means that only one additional cutting assembly needs to be added between the two swing arms, without changing the original structure of the swing arms or increasing the number of swing arms. This makes the entire cutting mechanism simple and compact, occupying less space and reducing production costs; furthermore, by arranging the first and second cutting assemblies alternately and side by side, it is possible to ensure that the first and second cutting assemblies do not interfere with each other, without having to raise or offset one of the first and second cutting assemblies. This makes the layout of the first and second cutting assemblies more reasonable and compact, further reducing the area occupied by the entire cutting mechanism and lowering production costs.

[0038] The winding device of this utility model, by including the above-mentioned cutting mechanism, enables the unwinding direction of the wound material roll to meet two different requirements, namely the upper and lower sides, and can improve the winding efficiency of foil materials. It also makes the structure of the entire winding device simple and compact, occupies less space, and has a lower production cost.

[0039] The coating equipment of this invention, by including the aforementioned winding device, enables the entire coating equipment to have high working efficiency, and ensures that the coating equipment has a simple and compact structure, occupies less space, and has low production costs.

[0051] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0052] Currently, the cutting mechanism can only meet one type of material roll cutting method. That is, a cutting mechanism can only cut foil on one side of the material roll, either the upper or lower side. When switching the cutting side of the material roll, it is necessary to disassemble and replace it with a new matching cutting mechanism and reassemble and debug it. The operation is cumbersome, time-consuming and labor-intensive, resulting in low foil winding efficiency.

[0053] Example 1

[0054] Therefore, this embodiment proposes a cutting mechanism that can selectively cut the foil on the upper and lower sides of the roll according to the specific unwinding direction requirements, making the foil cutting operation simple, convenient, time-saving, and labor-saving, thereby improving the winding efficiency of the foil; at the same time, the cutting mechanism has a simple and compact structure, occupies less space, and has low production costs. The foil is wound into a roll.

[0055] Specifically, such as Figures 1 to 5 As shown, the cutting mechanism 10 includes a rotating shaft 11, two swing arms 12, a first cutting assembly 13, and a second cutting assembly 14. The rotating shaft 11 is rotatably positioned upstream of the material roll 70, and the foil 60 is wound around the rotating shaft 11, allowing the rotating shaft 11 to rotate along its axial direction via the feeding action of the foil 60, thus providing a guiding and feeding function for the foil 60. Swing arms 12 are respectively arranged at opposite ends of the rotating shaft 11 along its axial direction. The two swing arms 12 are parallel and can swing around the axial direction of the rotating shaft 11, allowing them to swing to the upper or lower side of the material roll 70. The first cutting assembly 13 is connected between the two swing arms 12 and is used to swing to the lower side of the material roll 70 to cut the foil 60. Figure 3 As shown; the second cutter assembly 14 is connected between the two swing arms 12 and spaced apart from and arranged side by side with the first cutter assembly 13. The second cutter assembly 14 is used to swing to the upper side of the material roll 70 to cut the foil 60, as shown. Figure 4 As shown. Specifically, the axial direction of the rotation axis 11 is as follows: Figure 1 As shown by arrow A in the diagram.

[0056] By rotating the shaft 11 and positioning it upstream of the roll 70, the foil 60 is wound around the shaft 11 to form the roll 70. A swing arm 12 is positioned at each of the opposite ends of the shaft 11 along its axial direction. A first cutter assembly 13 and a second cutter assembly 14 are positioned between the two parallel swing arms 12, allowing the swing arms 12 to swing around the axial direction of the shaft 11, thereby driving the first cutter assembly 13 and the second cutter assembly 14 to swing synchronously. The first cutter assembly 13 swings to the lower side of the roll 70 to cut the foil 60, and the second cutter assembly 14 swings to the upper side of the roll 70 to cut the foil 60.

[0057] Compared to the prior art, the cutting mechanism 10 in this embodiment employs two mutually cooperating second cutting components 14 and first cutting components 13. This allows for selective cutting of the foil 60 on the upper and lower sides of the roll 70 according to the specific unwinding direction requirements. It eliminates the need to disassemble and replace the matching new cutting mechanism 10 and reassemble and debug it, making the foil cutting operation simple, convenient, time-saving, and labor-saving, thereby improving the winding efficiency of the foil 60. Furthermore, by integrating the first cutting component 13 and the second cutting component 14 between the two swing arms 12, only one additional cutting component is needed between the two swing arms 12. This design eliminates the need to alter the original structure of the swing arm 12 or increase the number of swing arms 12, resulting in a simple and compact structure for the entire cutting mechanism 10, which occupies less space and reduces production costs. Furthermore, by arranging the first cutting assembly 13 and the second cutting assembly 14 alternately and side by side, it ensures that the first cutting assembly 13 and the second cutting assembly 14 do not interfere with each other, without requiring one of the first cutting assembly 13 or the second cutting assembly 14 to be raised or staggered. This makes the layout of the first cutting assembly 13 and the second cutting assembly 14 more reasonable and compact, further reducing the area occupied by the entire cutting mechanism 10 and lowering production costs.

[0058] Furthermore, such as Figures 3 to 5 As shown, along the Z-axis, the axis of the rotating shaft 11 is lower than the highest point of the wound roll 70 and higher than the lowest point of the roll 70, so that the axis of the rotating shaft 11 is between the highest and lowest points of the roll 70. This allows the swing arm 12 to swing upward to the highest point of the roll 70 and downward to the lowest point of the roll 70 around the axis of the rotating shaft 11, which in turn facilitates the first cutter assembly 13 and the second cutter assembly 14 to smoothly perform the cutting operation of the foil 60.

[0059] Specifically, before winding, the foil 60 is passed through the rotating shaft 11 so that the specific transport direction of the foil 60 can be changed by passing the foil 60 through the upper or lower side of the rotating shaft 11; for example, as Figure 4 As shown, when the cutting position of the foil 60 is located above the roll 70, the foil 60 can pass through the lower side of the rotating shaft 11 to drive the rotating shaft 11 to rotate. At this time, along the Z-axis, the highest point of the roll 70 is higher than the axis of the rotating shaft 11, thus making the foil 60 present a transmission direction from the lower side to the upper side; as Figure 3 As shown, when the cutting position of the foil 60 is located below the roll 70, the foil 60 can pass through the upper side of the rotating shaft 11 to drive the rotating shaft 11 to rotate. At this time, along the Z-axis, the axis of the rotating shaft 11 is higher than the lowest point of the roll 70, thus making the foil 60 present a conveying direction from the upper side to the lower side. The specific conveying direction of the foil 60 is as follows: Figure 3As shown by arrow C in the diagram.

[0060] It is worth noting that, since the foil 60 can drive the rotating shaft 11 to rotate during the transmission process, the rotation of the rotating shaft 11 can provide a certain tension force to the foil 60, thereby ensuring the tension of the foil 60. This facilitates the smooth cutting of the foil 60 by the first cutting assembly 13 and the second cutting assembly 14, and ensures a good cutting effect on the foil 60.

[0061] Specifically, such as Figure 1 As shown, the cutting mechanism 10 also includes a third driving member 18. The fixed end of the third driving member 18 is located at one end of the rotating shaft 11, and the driving end of the third driving member 18 is drivenly connected to the swing arm 12. The third driving member 18 is used to synchronously drive the two swing arms 12 to swing around the axis of the rotating shaft 11. Specifically, the third driving member 18 can be a cylinder or a motor.

[0062] Specifically, such as Figure 1 As shown, mounting supports 16 are provided at both ends of the rotating shaft 11. That is, the rotating shaft 11 is rotatably connected to the mounting supports 16 along its axial direction, one end of the swing arm 12 is rotatably connected to the mounting supports 16, one end of the swing arm 12 is coaxially arranged with the rotating shaft 11, and the driving end of the third driving member 18 is drivenly connected to one end of the swing arm 12. The other end of the swing arm 12 is connected to the first cutter assembly 13 and the second cutter assembly 14. Here, the specific structure of the mounting supports 16 is not limited.

[0063] The first cutting blade assembly 13 is described in detail below:

[0064] Furthermore, such as Figure 1 As shown, the structure of the first cutter assembly 13 is the same as that of the second cutter assembly 14. The following will only describe the structure of the first cutter assembly 13 in detail, and will not describe the specific structure of the second cutter assembly 14.

[0065] Specifically, such as Figure 1 As shown, the other end of the swing arm 12 away from the rotation axis 11 is connected to a bracket 15, that is, one bracket 15 is connected to one swing arm 12; the first cutting assembly 13 includes a cutter 131 and a pressure roller 132; wherein, the cutter 131 is arranged parallel to the rotation axis 11, that is, the axis of the cutter 131 is parallel to the axis of the rotation axis 11, and the opposite ends of the cutter 131 are rotatably connected to two brackets 15 respectively, and the cutter 131 is used to rotatably cut the foil 60; the pressure roller 132 is arranged parallel and spaced apart on one side of the cutter 131, and the opposite ends of the pressure roller 132 are movably connected to two brackets 15 respectively, and the pressure roller 132 can extend or retract relative to the foil 60, so that the pressure roller 132 presses against or moves away from the foil 60. Here, the specific structure of the bracket 15 is not limited.

[0066] By configuring a pressure roller 132 and a cutter 131 that work together, when the foil 60 needs to be cut, the pressure roller 132 first presses the foil 60 against it, making it easier for the cutter 131 to cut the foil 60. This facilitates the cutting of the foil 60 by the cutter 131, making the cutting process simpler and easier. Furthermore, the pressure roller 132 applies a certain amount of pressure to the foil 60, ensuring that the foil 60 remains flat during the cutting process, preventing positional shifts or surface wrinkles under the action of the cutter 131. This effectively protects the foil 60 during cutting and ensures a good cutting effect. Figures 3 to 5 The distance between the foil 60 and the cutter 131 shown is only for simple illustration and does not affect the cutter 131 from cutting the foil 60 during rotation.

[0067] Furthermore, before cutting the foil 60, the pressure roller 132 can guide and press the foil 60 between itself and the roll 70. That is, the pressure roller 132 can assist in the transmission of the foil 60, thereby ensuring the smoothness and stability of the foil 60 throughout the transmission process.

[0068] Specifically, during the winding process to form the material roll 70, two swing arms 12 are first swung according to the unwinding direction of the material roll 70, so that the two swing arms 12 drive the cutter 131 and the pressure roller 132 to swing to the lower side of the material roll 70. At this time, the swing of the swing arms 12 can achieve the first approach and pressing action of the pressure roller 132 on the foil 60. When it is necessary to cut the foil 60, the pressure roller 132 is moved to further press and tighten the foil 60, so that the second approach and pressing action of the pressure roller 132 on the foil 60 can be achieved through the movement of the pressure roller 132 itself. That is, through the two approaches and pressing adjustments of the pressure roller 132 on the foil 60, the pressure of the pressure roller 132 on the foil 60 can be more accurately guaranteed, thereby better guaranteeing the pressing effect and guiding and conveying effect of the pressure roller 132 on the foil 60.

[0069] Furthermore, the blade of the cutter 131 has a long, serrated structure, that is, the blade is long along the axial direction of the cutter 131. At the same time, the entire long blade is serrated to increase the cutting area and cutting force between the blade and the foil 60, thereby facilitating the rapid cutting of the foil 60.

[0070] Specifically, such as Figure 1 and Figure 2As shown, the first cutter assembly 13 further includes a first drive member 133, a connecting rod 134, and a connecting member 135. The fixed end of the first drive member 133 is located inside one of the swing arms 12. The drive end of the first drive member 133 is drivenly connected to one end of the connecting rod 134, and the other end of the connecting rod 134 is hinged to the connecting member 135. The connecting member 135 is rotatably connected to the inside of the bracket 15 and connected to one end of the cutter 131. The first drive member 133 is used to pull the connecting rod 134 and the connecting member 135 to move, thereby driving the cutter 131 to rotate along its axial direction, thus causing the cutter 131 to rotate and cut the foil 60. Specifically, the first drive member 133 can be a motor or a cylinder, and the connecting member 135 can be a plate-like structure.

[0071] like Figure 1 As shown, by placing the fixed end of the first driving member 133 inside one of the swing arms 12 and providing a hinged connecting rod 134 and a connecting member 135, the structure of the entire first cutting assembly 13 can be made more reasonable and compact, thus reducing the area occupied by the entire cutting mechanism 10 and lowering production costs. On the other hand, the hinged movement between the connecting rod 134 and the connecting member 135 can better ensure the smoothness and reliability of the rotation of the cutting blade 131.

[0072] Furthermore, such as Figure 1 As shown, the first driving member 133, connecting rod 134 and connecting member 135 are arranged in two sets. One set of the first driving member 133, connecting rod 134 and connecting member 135 is set at one end of the cutter 131, and the other set of the first driving member 133, connecting rod 134 and connecting member 135 is set at the other end of the cutter 131. This allows the two first driving members 133 to pull the two connecting rods 134 simultaneously, thereby driving the relative ends of the cutter 131 to rotate at the same time, making the rotational stability and reliability of the cutter 131 higher.

[0073] Specifically, such as Figure 1 As shown, the first cutter assembly 13 also includes a second drive member 136. The fixed end of the second drive member 136 is located on the swing arm 12 or the bracket 15, and the driving end of the second drive member 136 is drivenly connected to the pressure roller 132. The second drive member 136 is used to drive the pressure roller 132 to extend and retract relative to the material roll 70 to press or move away from the foil 60. Specifically, the second drive member 136 can be a motor or a cylinder.

[0074] In this embodiment, as Figure 1As shown, the fixed end of the second drive member 136 is located on the outside of the swing arm 12, which ensures that the second drive member 136 will not interfere with the first drive member 133 and the connecting rod 134, and that the second drive member 136 will not occupy the usable space inside the swing arm 12. This further makes the structural layout of the entire first cutter assembly 13 more reasonable and compact, better reduces the area occupied by the entire cutter mechanism 10, and lowers the production cost.

[0075] Specifically, such as Figure 1 As shown, two second driving members 136 can be provided. The fixed ends of the two second driving members 136 are respectively connected to the outer sides of the two swing arms 12. One second driving member 136 is used to drive the pressure roller 132 of the first cutter assembly 13 to perform telescopic movement, and the other second driving member 136 is used to drive the pressure roller 132 of the second cutter assembly 14 to perform telescopic movement. This ensures that the telescopic movements of the pressure roller 132 of the first cutter assembly 13 and the pressure roller 132 of the second cutter assembly 14 do not interfere with each other. In other embodiments, only one second driving member 136 can be provided. This second driving member 136 is connected to the pressure roller 132 of the first cutter assembly 13 and the pressure roller 132 of the second cutter assembly 14 through a driving connection. This allows for the selection of which pressure roller 132 of the first cutter assembly 13 or the pressure roller 132 of the second cutter assembly 14 to perform telescopic movement according to the telescopic requirements, thereby reducing the number of second driving members 136 and lowering production costs.

[0076] Furthermore, the first cutter assembly 13 also includes a sensor (not shown in the figure), which is disposed on the side of the pressure roller 132 near the foil 60. The sensor is used to sense the outer diameter of the roll 70, and the sensor is communicatively connected to the first drive member 133 and the second drive member 136 mentioned above.

[0077] Specifically, when the sensor detects that the outer diameter of the material roll 70 has reached the preset outer diameter, the sensor feeds back the detection result to the first drive member 133 and the second drive member 136. First, the second drive member 136 drives the pressure roller 132 to extend, so that the pressure roller 132 moves closer to and presses against the foil 60. Then, the first drive member 133 drives the connecting rod 134 and the connecting member 135 to move, thereby driving the first cutter 131 to rotate along its axial direction, so that the blade of the first cutter 131 can rotate and cut the foil 60 during the rotation. The sensor can be a through-beam fiber optic sensor.

[0078] By setting up a sensing element, on the one hand, the foil 60 can be cut only when the outer diameter of the material roll 70 reaches the preset outer diameter, so as to ensure the accuracy of the cutting position of the foil 60 and avoid the problem of foil 60 cutting position deviation; on the other hand, it can cut material rolls 70 with different outer diameters according to processing requirements, thereby improving the versatility and applicability of the entire cutting mechanism 10.

[0079] Furthermore, such as Figure 1 As shown, at least one reinforcing shaft 17 is connected between the two swing arms 12 to improve the overall structural stability of the two swing arms 12, thereby improving the installation stability and reliability of the first cutter assembly 13 and the second cutter assembly 14 on the swing arms 12. In this embodiment, a reinforcing shaft 17 is connected between the two swing arms 12, and the specific number of reinforcing shafts 17 is not limited.

[0080] The cutting mechanism 10 in this embodiment, by arranging the first cutting component 13 and the second cutting component 14 side by side on the two swing arms 12, can selectively cut the foil 60 on the upper and lower sides of the material roll 70 according to the specific unwinding direction requirements of the material roll 70. It has high flexibility, is simple and convenient to operate, saves time and effort, and can improve the winding efficiency of the foil 60. Furthermore, by arranging the first cutting component 13 and the second cutting component 14 side by side and integrating them between the two swing arms 12, it is not necessary to change the original setting structure of the swing arms 12 or increase the number of swing arms 12, nor is it necessary to raise or misalign one of the first cutting component 13 and the second cutting component 14. As a result, the entire cutting mechanism 10 has a simple and compact structure, occupies less space, and reduces production costs.

[0081] In this embodiment, the cutting mechanism 10 has the fixed end of the first driving member 133 located inside one of the swing arms 12, and is provided with a hinged connecting rod 134 and a connecting member 135; at the same time, the fixed end of the second driving member 136 is located outside the swing arm 12; so that the structural layout of the entire first cutting assembly 13 is reasonable and compact, thereby further reducing the area occupied by the entire cutting mechanism 10 and reducing production costs.

[0082] In this embodiment, the cutting mechanism 10 first uses the third driving member 18 to swing the swing arm 12 to achieve the first approach and pressing action of the pressure roller 132 on the foil 60. Then, the second driving member 136 drives the pressure roller 132 to achieve the second approach and pressing action on the foil 60. This allows for adjustment of the pressure roller 132 on the foil 60 through two approaches and pressing actions, thereby better ensuring the pressing effect and guiding and conveying effect of the pressure roller 132 on the foil 60.

Figures 3 to 5As shown, the winding device includes a frame 20, a winding roller, a cutting mechanism 10 as described in Embodiment 1 above, and several guide rollers 40. The winding roller is rotatably mounted on the frame 20 along its axial direction and is used to rotate and wind the foil 60 to form a roll 70. The rotating shaft 11 of the cutting mechanism 10 is rotatably mounted on the frame 20 along its axial direction; that is, the mounting bracket 16 is fixedly connected to the frame 20, and the rotating shaft 11 is located on the upstream side of the winding roller. Several guide rollers 40 are all located upstream of the cutting mechanism 10, and the foil 60 is sequentially guided and wound around each guide roller 40, so that the guide rollers 40 can provide a guiding and pulling effect for the foil 60. The specific structure of the frame 20 is not limited here.

[0085] Furthermore, such as Figures 3 to 5 As shown, the winding device also includes a support frame 50, which is fixedly connected to the frame body 20 to provide strength support for the entire frame body 20, ensuring high structural strength. Furthermore, guide rollers 51 are rotatably mounted on the support frame 50 to guide and pull the foil material 60. In this embodiment, the support frame 50 has an I-shaped structure, and a guide roller 51 is rotatably connected to each of the four corners of the I-shaped support frame 50.

[0086] Specifically, such as Figures 3 to 5 As shown, the take-up roller includes a first take-up roller 31 and a second take-up roller 32, which are located on opposite sides of the support frame 50. When the first take-up roller 31 winds up the material roll 70 with the required preset outer diameter, the foil 60 is cut by the aforementioned cutting mechanism 10. The cut foil 60 is then wound around the second take-up roller 32 so that the second take-up roller 32 begins to rotate and wind up. After that, when the second take-up roller 32 winds up the material roll 70 with the required preset outer diameter, the foil 60 is cut by the aforementioned cutting mechanism 10.

[0087] By setting two take-up rollers, the first take-up roller 31 and the second take-up roller 32, the foil 60 can be taken up immediately after the first take-up roller 31 finishes taking up the foil, which greatly saves the waiting time and can further improve the taking up efficiency of the foil 60.

[0088] Specifically, the specific winding sequence of the first take-up roller 31 and the second take-up roller 32 is not limited; that is, as follows: Figure 3 and Figure 4 As shown, depending on the requirements, the first take-up roller 31 can be used for winding first, and then the second take-up roller 32 can be used for winding; alternatively, as shown... Figure 5As shown, the second take-up roller 32 is used for winding first, and then the first take-up roller 31 is used for winding. The first take-up roller 31 is located between the second take-up roller 32 and the cutting mechanism 10. That is, the first take-up roller 31 is set closer to the cutting mechanism 10, and the second take-up roller 32 is set away from the cutting mechanism 10.

[0089] Specifically, such as Figure 5 As shown, when using the second take-up roller 32, which is away from the cutter mechanism 10, for winding: First, the swing arm 12 drives the first cutter assembly 13 and the second cutter assembly 14 to swing as a whole, so that the first cutter assembly 13 swings to the lower side of the first take-up roller 31 or the second cutter assembly 14 swings to the upper side of the first take-up roller 31; then, the second drive member 136 of the first cutter assembly 13 drives the pressure roller 132 to extend closer to the first take-up roller 31, so that the foil 60 is guided to pass through the pressure roller 132 of the first cutter assembly 13 and the first take-up roller 31, or the second drive member 136 of the second cutter assembly 14 drives the pressure roller 132 to extend closer to the first take-up roller 31. The first take-up roller 31 extends in the direction of the foil material 60, so that the foil material 60 is guided and passed between the pressure roller 132 of the second cutter assembly 14 and the first take-up roller 31. Finally, the foil material 60 is guided by the guide roller 51 on the support frame 50 and then wound around the second take-up roller 32 so that the second take-up roller 32 can take up the foil material 60. When the outer diameter of the roll 70 formed on the second take-up roller 32 reaches the preset outer diameter, the cutter 131 of the first cutter assembly 13 or the second cutter assembly 14 is rotated to cut the foil material 60 on the lower or upper side of the first take-up roller 31. Thus, the foil material 60 is automatically taken up by the second take-up roller 32 which is located away from the cutter mechanism 10.

[0090] like Figure 5 As shown, by guiding the foil 60 between the pressure roller 132 and the first take-up roller 31, the pressure roller 132 guides the foil 60, ensuring that the foil 60 can be smoothly wound onto the second take-up roller 32. That is, when two take-up rollers, the first take-up roller 31 and the second take-up roller 32, are used for winding, on the one hand, the guiding and transmission of the foil 60 can be well guaranteed, ensuring the smoothness and stability of the foil 60 during the guiding and transmission process; on the other hand, there is no need to set up an additional guiding structure to guide and transmit the foil 60 to the second take-up roller 32. The pressure roller 132 in the cutter mechanism 10 can be used for guiding and transmission, thus ensuring that the structure of the entire winding device is simpler and more compact, occupies less space, and has lower production costs.

[0091] And, as Figures 3 to 5As shown, when two take-up rollers, the first take-up roller 31 and the second take-up roller 32, are set up for take-up, only one cutter mechanism 10 is needed to guide and cut the foil 60 on the two take-up rollers. This reduces the number of cutter mechanisms 10, making the structure of the entire take-up device simpler and more compact, occupying less space, and reducing production costs.

[0092] Example 3

[0093] This embodiment proposes a coating device, which includes an unwinding device, a coating device, a drying device, and a winding device as described in Embodiment 2 above. The unwinding device is used to unwind foil 60. The coating device is located downstream of the unwinding device and is used to coat the foil 60. The drying device is located downstream of the coating device and is used to heat and dry the coated foil 60. The winding device is located downstream of the drying device, that is, the plurality of guide rollers 40 in Embodiment 2 above are located downstream of the drying device, and the winding device can automatically wind the dried foil 60 into a roll 70 with a preset outer diameter.

[0094] Specifically, the unwinding device can be an unwinding roller structure, the coating device can adopt a coating structure commonly used in the prior art, and the drying device can be an electrically heated drying oven structure.

[0095] The specific working process of the coating equipment in this embodiment is as follows: Figure 3 As shown, the foil 60 is wound on the first take-up roller 31 and cut from the underside of the roll 70.

[0096] First, the unwinding device automatically unwinds the foil 60 wound on it, so that the foil 60 is guided and transported to the coating device, where the coating device coats the foil 60. Then, the coated foil 60 is guided and transported to the drying device, where the drying device heats and dries the foil 60.

[0097] Then, the dried foil 60 is guided and conveyed to the winding device. That is, the heated and dried foil 60 is wound around each guide roller 40 in sequence, and then passes through the foil 60 from the upper side of the rotating shaft 11 to drive the rotating shaft 11 to rotate. At this time, along the Z-axis, the axis of the rotating shaft 11 is higher than the lowest point of the roll 70, so that the foil 60 presents a conveying direction from the upper side to the lower side. At this time, according to the unwinding direction requirement of the roll 70, the two swing arms 12 are swung so that the two swing arms 12 drive the first cutter assembly 13 to swing to the lower side of the roll 70, so that the pressure roller 132 of the first cutter assembly 13 approaches the foil 60 to perform the first approach and pressure on the foil 60.

[0098] Subsequently, when the sensor detects that the outer diameter of the material roll 70 wound on the first winding shaft reaches the preset outer diameter, the sensor feeds back the detection result to the first drive member 133 and the second drive member 136. First, the second drive member 136 drives the pressure roller 132 to extend, so that the pressure roller 132 comes closer to press against the foil 60 for the second time. Then, the first drive member 133 pulls the connecting rod 134 and the connecting member 135 to move, thereby driving the first cutter 131 to rotate along its axial direction, so that the blade of the first cutter 131 can rotate and cut the foil 60 during the rotation. Thus, the entire process of unwinding, coating, drying, cutting and winding of the foil 60 is automatically completed.

[0099] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
