[0049] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any manner.

[0050] Any feature disclosed in this specification, unless specifically described, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically described, each feature is only an example of a series of equivalent or similar features. Throughout the specification, the same reference numerals indicate the same elements.

[0051] To make the technical problems solved by the present invention, the technical solutions adopted, and the achieved technical effects clearer, the technical solutions of the present invention will be further described below with reference to the drawings and through specific embodiments.

[0052] Currently, the cutter mechanism can only meet one type of coil cutting method, that is, one cutter mechanism can only cut the foil unidirectionally on the upper side or the lower side of the coil; when switching the cutting side of the coil, it is necessary to disassemble and replace the matching new cutter mechanism and perform reassembly and debugging, which is cumbersome, time-consuming and laborious, resulting in a low winding efficiency of the foil.

[0053] Embodiment 1

[0054] To this end, a cutting tool mechanism is proposed in this embodiment. This cutting tool mechanism can selectively cut the foil on the upper side and the lower side of the coil according to the specific unwinding direction requirements of the coil, making the operation of cutting the foil simple, convenient, time-saving and labor-saving, thereby improving the winding efficiency of the foil. At the same time, the structure of this cutting tool mechanism is relatively simple and compact, occupying less space and having a lower production cost. Among them, the foil is wound to form a coil.

[0055] Specifically, as Figures 1 to 5 shown, the cutting tool mechanism 10 includes a rotating shaft 11, two swing arms 12, a first cutting tool assembly 13 and a second cutting tool assembly 14. Among them, the rotating shaft 11 is rotatably arranged upstream of the coil 70, and the foil 60 is wound around the rotating shaft 11 so as to drive the rotating shaft 11 to rotate along its axis through the running of the foil 60, thereby providing a guiding and leading function for the foil 60 through the rotating shaft 11. Swing arms 12 are respectively arranged at opposite ends of the rotating shaft 11 along its axis. The two swing arms 12 are parallel to each other and can swing around the axis of the rotating shaft 11 so that the swing arms 12 can swing to the upper side or the lower side of the coil 70. The first cutting tool assembly 13 is connected between the two swing arms 12 and is used to swing to the lower side of the coil 70 to cut the foil 60, as Figure 3 shown; the second cutting tool assembly 14 is connected between the two swing arms 12 and is arranged at an interval and in parallel with the first cutting tool assembly 13. The second cutting tool assembly 14 is used to swing to the upper side of the coil 70 to cut the foil 60, as Figure 4 shown. Among them, the axis direction of the rotating shaft 11 is specifically as Figure 1 shown by the arrow A in.

[0056] By rotatably arranging the rotating shaft 11 upstream of the coil 70, winding the foil 60 around the rotating shaft 11 to form the coil 70; and respectively arranging swing arms 12 at opposite ends of the rotating shaft 11 along its axis, and arranging a first cutting tool assembly 13 and a second cutting tool assembly 14 between the two parallel swing arms 12, enabling the swing arms 12 to swing around the axis of the rotating shaft 11 to drive the first cutting tool assembly 13 and the second cutting tool assembly 14 to swing synchronously, so that the first cutting tool assembly 13 swings to the lower side of the coil 70 to cut the foil 60, and the second cutting tool assembly 14 swings to the upper side of the coil 70 to cut the foil 60.

[0057] In comparison with the prior art, the cutting tool mechanism 10 in this embodiment adopts the above-mentioned second cutting tool assembly 14 and first cutting tool assembly 13 that cooperate with each other, and can selectively cut the foil 60 on the upper side and the lower side of the coil 70 according to the specific unwinding direction requirements of the coil 70. There is no need to disassemble and replace a new cutting tool mechanism 10 that matches it and perform reassembly and debugging, making the operation of cutting the foil 60 simple, convenient, time-saving and labor-saving, thereby improving the winding efficiency of the foil 60; at the same time, integrating the first cutting tool assembly 13 and the second cutting tool assembly 14 between the two swing arms 12, that is, only one set of cutting tool assemblies needs to be added between the two swing arms 12, without changing the original structure of the swing arms 12 or adding the number of swing arms 12 additionally, making the structure of the entire cutting tool mechanism 10 simple and compact, occupying less space and reducing the production cost; and, by arranging the first cutting tool assembly 13 and the second cutting tool assembly 14 at intervals and side by side, it is possible to ensure that there is no interference between the first cutting tool assembly 13 and the second cutting tool assembly 14, and there is no need to set one of the first cutting tool assembly 13 and the second cutting tool assembly 14 at a higher position with a dislocation, making the layout of the first cutting tool assembly 13 and the second cutting tool assembly 14 more reasonable and compact, further reducing the occupied area of the entire cutting tool mechanism 10 and reducing the production cost.

[0058] Furthermore, as Figures 3 to 5 shown, along the Z-axis, the axis of the rotating shaft 11 is lower than the highest point of the coil 70 formed by winding and higher than the lowest point of the coil 70, so that the axis of the rotating shaft 11 can be between the highest point and the lowest point of the coil 70, which is conducive to the swing arm 12 swinging upward around the axis of the rotating shaft 11 to the highest point of the coil 70 and swinging downward to the lowest point of the coil 70, and further conducive to the first cutting tool assembly 13 and the second cutting tool assembly 14 smoothly cutting the foil 60.

[0059] Specifically, before winding, the foil 60 is passed through the rotating shaft 11, so as to change the specific transmission direction of the foil 60 by passing the foil 60 from the upper side or the lower side of the rotating shaft 11; for example, as Figure 4 shown, when the cutting position of the foil 60 is on the upper side of the coil 70, the foil 60 can be passed 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 coil 70 is higher than the axis of the rotating shaft 11, so that the foil 60 shows a transmission direction from the lower side to the upper side; as Figure 3 shown, when the cutting position of the foil 60 is on the lower side of the coil 70, the foil 60 can be passed 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 coil 70, so that the foil 60 shows a transmission direction from the upper side to the lower side. Among them, the transmission direction of the foil 60 is specifically as Figure 3as shown by arrow C therein.

[0060] It should be noted that since the foil 60 can drive the rotating shaft 11 to rotate by itself during the transmission process, a certain tension can be provided for the foil 60 through the rotation of the rotating shaft 11, so as to ensure the tension state of the foil 60, which is beneficial to the subsequent smooth cutting of the foil 60 by the first cutting knife assembly 13 and the second cutting knife assembly 14, and can ensure a better cutting effect on the foil 60.

[0061] Specifically, as Figure 1 shown, the cutting knife mechanism 10 further includes a third driving member 18. The fixed end of the third driving member 18 is arranged at one end of the rotating shaft 11, and the driving end of the third driving member 18 is drivingly 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. Among them, the third driving member 18 can specifically be a cylinder or a motor.

[0062] Specifically, as Figure 1 shown, mounting brackets 16 are arranged at both opposite ends of the rotating shaft 11. That is, the rotating shaft 11 is rotatably connected to the mounting brackets 16 along its axis direction. One end of the swing arm 12 is rotatably connected to the mounting brackets 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 drivingly connected to one end of the swing arm 12. The other end of the swing arm 12 is connected to the first cutting knife assembly 13 and the second cutting knife assembly 14. Here, the specific structure of the mounting brackets 16 is not limited.

[0063] The following is a specific description of the first cutting knife assembly 13:

[0064] Furthermore, as Figure 1 shown, the structure of the first cutting knife assembly 13 is the same as that of the second cutting knife assembly 14. The following only details the structure of the first cutting knife assembly 13, and the specific structure of the second cutting knife assembly 14 will not be described.

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

[0066] By providing a pressure roller 132 and a cutter 131 that cooperate with each other, when it is necessary to cut the foil 60, the pressure roller 132 can be first pressed against the foil 60 to facilitate the cutter 131 to cut the pressed foil 60. On the one hand, it is convenient for the cutter 131 to cut the foil 60, making the cutting of the foil 60 relatively simple and easy. On the other hand, a certain pressing force can be applied to the foil 60 through the pressure roller 132, so that the foil 60 can remain flat during the cutting process, preventing the foil 60 from shifting in position or wrinkling on the surface under the action of the cutter 131. Thus, the foil 60 can be better protected during the cutting process, and the cutting effect on the foil 60 can be ensured to be better. Among them, Figures 3 to 5 The distance between the foil 60 and the cutter 131 shown in [figure] is only for simple illustration and does not affect the cutter 131 cutting the foil 60 during rotation.

[0067] Furthermore, before cutting the foil 60, since the pressure roller 132 can guide and press the foil 60 between it and the coil 70, that is, the pressure roller 132 can assist in transporting the foil 60, thereby ensuring the smoothness and stability of the foil 60 during the entire transportation process.

[0068] Specifically, during the process of winding to form the coil 70, first swing the two swing arms 12 according to the unwinding direction requirement of the coil 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 coil 70. At this time, the first approach and pressing action of the pressure roller 132 on the foil 60 can be realized through the swing of the swing arms 12; when it is necessary to cut the foil 60, then move the pressure roller 132 to further press and tighten the foil 60, so as to realize the second approach and pressing action on the foil 60 through the movement of the pressure roller 132 itself; that is, through the two approach and pressing adjustments of the pressure roller 132 on the foil 60, the magnitude of the pressing force of the pressure roller 132 pressing against the foil 60 can be more accurately ensured, and thus the pressing effect and the guiding and transporting effect of the pressure roller 132 on the foil 60 can be better ensured.

[0069] Furthermore, the cutting edge of the cutter 131 is in the shape of a long strip with serrations, that is, the cutting edge is in a long strip shape along the axis of the cutter 131, and at the same time, the entire long strip-shaped cutting edge is arranged in a serrated shape, so as to increase the cutting area and cutting force between the cutting edge and the foil 60, and thus it is beneficial to quickly cut the foil 60.

[0070] Specifically, as shown in Figure 1 and Figure 2As shown in the figure, the first cutter assembly 13 further includes a first driving member 133, a connecting rod 134, and a connecting member 135. Among them, the fixed end of the first driving member 133 is provided inside one of the swing arms 12. The driving end of the first driving member 133 is drivingly connected to one end of the connecting rod 134. The other end of the connecting rod 134 is hinged to the connecting member 135. And 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 driving member 133 is used to pull the connecting rod 134 and the connecting member 135 to move, so as to drive the cutter 131 to rotate along its axis, thereby enabling the cutter 131 to rotate and cut the foil 60. Among them, the first driving member 133 can specifically be a motor or a cylinder, and the connecting member 135 can specifically be a plate-like structure.

[0071] As Figure 1 shown, by arranging the fixed end of the first driving member 133 inside one of the swing arms 12 and providing the hinged connecting rod 134 and connecting member 135; on the one hand, it can make the structural layout of the entire first cutter assembly 13 more reasonable and compact, better reduce the occupied area of the entire cutter mechanism 10, and reduce production costs; on the other hand, it can better ensure the smoothness and reliability of the rotation of the cutter 131 through the hinged movement between the connecting rod 134 and the connecting member 135.

[0072] Furthermore, as Figure 1 shown, there are two sets of the first driving member 133, the connecting rod 134, and the connecting member 135 as a whole. One set of the first driving member 133, the connecting rod 134, and the connecting member 135 is arranged at one end of the cutter 131, and the other set of the first driving member 133, the connecting rod 134, and the connecting member 135 is arranged at the other end of the cutter 131, so as to be able to simultaneously pull the two connecting rods 134 synchronously through the two first driving members 133, and further be able to simultaneously drive the opposite ends of the cutter 131 to rotate, making the rotation stability and reliability of the cutter 131 higher.

[0073] Specifically, as Figure 1 shown, the first cutter assembly 13 further includes a second driving member 136. The fixed end of the second driving member 136 is provided on the swing arm 12 or the bracket 15. The driving end of the second driving member 136 is drivingly connected to the pressure roller 132. The second driving member 136 is used to drive the pressure roller 132 to expand and contract relative to the material roll 70 to press against or away from the foil 60. Among them, the second driving member 136 can specifically be a motor or a cylinder.

[0074] In this embodiment, as Figure 1As shown, the fixed end of the second driving member 136 is disposed outside the swing arm 12, which can prevent the second driving member 136 from interfering with the first driving member 133 and the connecting rod 134, and the second driving member 136 does not occupy the inner space of the swing arm 12, further making the structural layout of the entire first cutter assembly 13 more reasonable and compact, better reducing the occupied area of the entire cutter mechanism 10 and lowering the production cost.

[0075] Specifically, as Figure 1 shown, two second driving members 136 can be provided. The fixed ends of the two second driving members 136 are respectively connected to the outside of the two swing arms 12. One second driving member 136 is used to drive the roller 132 of the first cutter assembly 13 to perform telescopic movement, and the other second driving member 136 is used to drive the roller 132 of the second cutter assembly 14 to perform telescopic movement, so that the telescopic movements of the roller 132 of the first cutter assembly 13 and the roller 132 of the second cutter assembly 14 do not interfere with each other. In other embodiments, only one second driving member 136 can also be provided to drive-connect with the roller 132 of the first cutter assembly 13 and the roller 132 of the second cutter assembly 14 through the second driving member 136, so as to specifically select to drive the roller 132 of the first cutter assembly 13 or the roller 132 of the second cutter assembly 14 to perform telescopic movement according to the telescopic requirements, in order to reduce the number of second driving members 136 provided and lower the production cost.

[0076] Further, the first cutter assembly 13 further includes a sensing member (not shown in the figure). The sensing member is disposed on the side of the roller 132 close to the foil 60. The sensing member is used to sense the outer diameter of the coil 70, and the sensing member is communicatively connected to the above-mentioned first driving member 133 and second driving member 136.

[0077] Specifically, when the sensing member detects that the outer diameter of the coil 70 reaches the preset outer diameter, at this time, the sensing member feeds back the detection result to the first driving member 133 and the second driving member 136. First, the second driving member 136 is made to drive the roller 132 to extend, so that the roller 132 approaches and presses against the foil 60; then the first driving member 133 is made to drive the connecting rod 134 and the connecting member 135 to move, thereby driving the first cutter 131 to rotate along its axis, so that the cutting edge of the first cutter 131 rotates to cut the foil 60 during the rotation. Among them, the sensing member can specifically be a through-beam fiber optic sensor.

[0078] By providing the sensing member, on the one hand, the foil 60 can be cut only when the outer diameter of the coil 70 reaches the preset outer diameter, so as to ensure the accuracy of the cutting position of the foil 60 and prevent the problem of the cutting position of the foil 60 shifting; on the other hand, coils 70 with various different outer diameters can be cut according to the processing requirements, thereby improving the versatility and application range of the entire cutter mechanism 10.

[0079] Furthermore, as Figure 1 shown, at least one reinforcing shaft 17 is connected between the two swing arms 12, so as to improve the overall structural stability of the two swing arms 12 through the reinforcing shaft 17, and further improve 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, one reinforcing shaft 17 is connected between the two swing arms 12. Here, the specific number of the reinforcing shafts 17 is not limited.

[0080] In the cutter mechanism 10 of this embodiment, the first cutter assembly 13 and the second cutter assembly 14 are arranged in parallel on the two swing arms 12, so as to be able to selectively cut the foil 60 on the upper side and the lower side of the coil 70 according to the specific unwinding direction requirement of the coil 70. It has high flexibility in use, is simple and convenient to operate, saves time and effort, and can improve the winding efficiency of the foil 60; moreover, the first cutter assembly 13 and the second cutter assembly 14 are arranged in parallel and integrated between the two swing arms 12, without changing the original structure of the swing arms 12 or additionally increasing the number of swing arms 12, nor does it require one of the first cutter assembly 13 and the second cutter assembly 14 to be set at a higher position with a dislocation, so that the structure of the entire cutter mechanism 10 is simple and compact, occupies less space, and reduces the production cost.

[0081] In the cutter mechanism 10 of this embodiment, the fixed end of the first driving member 133 is arranged inside one of the swing arms 12, and the hinged connecting rod 134 and the connecting member 135 are arranged; at the same time, the fixed end of the second driving member 136 is arranged outside the swing arm 12; so as to make the structural layout of the entire first cutter assembly 13 reasonable and compact, so as to further reduce the occupied area of the entire cutter mechanism 10 and reduce the production cost.

[0082] In the cutter mechanism 10 of this embodiment, the third driving member 18 first swings the swing arm 12 to realize the first approaching and pressing action of the pressing roller 132 on the foil 60, and then the second driving member 136 drives the pressing roller 132 to realize the second approaching and pressing action on the foil 60, so as to be able to adjust the two approaching and pressing actions of the pressing roller 132 on the foil 60, and further be able to better ensure the pressing effect and the guiding and transmitting effect of the pressing roller 132 on the foil 60.

[0083] Embodiment II

[0084] In this embodiment, a winding device is proposed, as Figures 3 to 5As shown in the figure, the rewinding device includes a frame body 20, a rewinding roller, a cutting mechanism 10 as in the first embodiment above, and a plurality of guide rollers 40; wherein, the rewinding roller is rotatably arranged along its axial direction in the frame body 20, and the rewinding roller is used for rotatably rewinding the foil 60 to form a coil 70; the rotating shaft 11 in the cutting mechanism 10 is rotatably arranged along its axial direction in the frame body 20, that is, the above-mentioned mounting seat 16 is fixedly connected to the frame body 20, and the rotating shaft 11 is located on one side upstream of the rewinding roller; a plurality of guide rollers 40 are all arranged upstream of the cutting mechanism 10, and the foil 60 is sequentially guided and wound around each guide roller 40, so as to be able to provide a guiding and leading function for the foil 60 through each guide roller 40. Here, the specific structure of the frame body 20 is not limited.

[0085] Further, as Figures 3 to 5 shown in the figure, the rewinding device further includes a support frame 50, and the support frame 50 is fixedly connected to the frame body 20, so as to be able to provide strength support for the entire frame body 20 through the support frame 50 and ensure that the frame body 20 has a relatively high structural strength; and, a guide roller 51 is rotatably arranged on the support frame 50, so as to be able to provide a guiding and leading function for the foil 60 through the guide roller 51. In this embodiment, the support frame 50 is specifically in 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, as Figures 3 to 5 shown in the figure, the rewinding roller includes a first rewinding roller 31 and a second rewinding roller 32, and the first rewinding roller 31 and the second rewinding roller 32 are respectively located on opposite sides of the support frame 50; when the first rewinding roller 31 rewinds to form a coil 70 with a required preset outer diameter, the foil 60 is cut off by the above-mentioned cutting mechanism 10; then the cut foil 60 is wound around the second rewinding roller 32, so that the second rewinding roller 32 starts to rotate and rewind; after that, when the second rewinding roller 32 rewinds to form a coil 70 with a required preset outer diameter, the foil 60 is cut off by the above-mentioned cutting mechanism 10 again.

[0087] By providing two rewinding rollers, namely the first rewinding roller 31 and the second rewinding roller 32, it is possible to immediately rewind the foil 60 through the second rewinding roller 32 after the first rewinding roller 31 finishes rewinding, greatly saving the waiting interruption time, and thus further improving the rewinding efficiency of the foil 60.

[0088] Specifically, there is no limit to the specific rewinding sequence of the first rewinding roller 31 and the second rewinding roller 32, that is, as Figure 3 and Figure 4 shown in the figure, it is possible to first use the first rewinding roller 31 for rewinding according to requirements, and then use the second rewinding roller 32 for rewinding; it is also possible to, as Figure 5As shown in the figure, first use the second winding roller 32 for winding, and then use the first winding roller 31 for winding. Among them, the first winding roller 31 is located between the second winding roller 32 and the cutting mechanism 10, that is to say, the first winding roller 31 is arranged closer to the cutting mechanism 10, and the second winding roller 32 is arranged away from the cutting mechanism 10.

[0089] Specifically, as Figure 5 shown in the figure, when using the second winding roller 32 away from the cutting mechanism 10 for winding; first, make the swing arm 12 drive the first cutting assembly 13 and the second cutting assembly 14 as a whole to swing, so that the first cutting assembly 13 swings to the lower side of the first winding roller 31 or the second cutting assembly 14 swings to the upper side of the first winding roller 31; then, make the second driving member 136 of the first cutting assembly 13 drive the pressure roller 132 to extend towards the first winding roller 31, so that the foil 60 is guided through between the pressure roller 132 of the first cutting assembly 13 and the first winding roller 31, or make the second driving member 136 of the second cutting assembly 14 drive the pressure roller 132 to extend towards the first winding roller 31, so that the foil 60 is guided through between the pressure roller 132 of the second cutting assembly 14 and the first winding roller 31; finally, make the foil 60 pass through the guide roller 51 on the support frame 50 for guiding and then wind around the second winding roller 32, so that the second winding roller 32 winds the foil 60; when the outer diameter of the coil 70 formed by winding on the second winding roller 32 reaches the preset outer diameter, then make the cutter 131 of the first cutting assembly 13 or the second cutting assembly 14 rotate and cut the foil 60 under the lower side or the upper side of the first winding roller 31; thus realizing the automatic winding of the foil 60 on the second winding roller 32 arranged away from the cutting mechanism 10.

[0090] As Figure 5 shown in the figure, by guiding the foil 60 through between the pressure roller 132 and the first winding roller 31, the guiding effect of the pressure roller 132 on the foil 60 can be used to ensure that the foil 60 can be smoothly wound around the second winding roller 32, that is to say, in the case of setting two winding rollers, namely the first winding roller 31 and the second winding roller 32, for winding; on the one hand, it can better ensure the guiding and transporting effect on the foil 60 and ensure the smoothness and stability of the foil 60 during the guiding and transporting process; on the other hand, there is no need to additionally set a guiding structure to guide and transport the foil 60 to the second winding roller 32, and the pressure roller 132 in the cutting mechanism 10 can be used for guiding and transporting, thereby 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 winding rollers, i.e., the first winding roller 31 and the second winding roller 32, are provided for winding, only one cutter mechanism 10 needs to be provided to realize the guiding and cutting operations on the foil 60 on the two winding rollers, so as to reduce the number of cutter mechanisms 10 provided, further making the structure of the entire winding device simpler and more compact, occupying less space and having lower production costs.

[0092] Embodiment III

[0093] In this embodiment, a coating device is proposed. The coating device includes an unwinding device, a coating device, a drying device, and a winding device as described in Embodiment II above. Among them, the unwinding device is used to unwind the foil 60; the coating device is arranged downstream of the unwinding device and is used to coat the foil 60; the drying device is arranged downstream of the coating device and is used to heat and dry the coated foil 60; the winding device is arranged downstream of the drying device. That is, several guiding rollers 40 in Embodiment II above are arranged downstream of the drying device, and the winding device can automatically wind the dried foil 60 to form a coil 70 with a preset outer diameter.

[0094] Specifically, the above-mentioned unwinding device can specifically be an unwinding roller structure, the coating device can adopt a common coating structure in the prior art, and the drying device can specifically adopt an electric heating drying box structure.

[0095] The specific working process of the coating device in this embodiment is as follows, as Figure 3 shown, winding is performed on the first winding roller 31, and the foil 60 is cut from the lower side of the coil 70:

[0096] First, the unwinding device automatically unwinds the foil 60 wound thereon, so that the foil 60 is guided and transmitted to the coating device, and the coating device coats the transmitted foil 60; then, the coated foil 60 is guided and transmitted to the drying device, and the drying device heats and dries the transmitted foil 60.

[0097] Then, the dried foil 60 is guided and transmitted to the winding device. That is, the heated and dried foil 60 is wound around each guiding roller 40 in turn, 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 coil 70, so that the foil 60 shows a transmission direction from the upper side to the lower side; at this time, swing the two swing arms 12 according to the unwinding direction requirement of the coil 70, so that the two swing arms 12 drive the first cutter assembly 13 to swing to the lower side of the coil 70, and the pressure roller 132 of the first cutter assembly 13 approaches the foil 60 to perform the first approach and pressing on the foil 60.

[0098] After that, when the inductor detects that the outer diameter of the material roll 70 wound on the first take-up reel reaches the preset outer diameter, the inductor feeds back the detection result to the first driving member 133 and the second driving member 136. First, the second driving member 136 is made to drive the pressure roller 132 to extend, so that the pressure roller 132 approaches and presses against the foil 60 for the second time; then the first driving member 133 is made to pull 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 cutting edge of the first cutter 131 can rotate to cut off the foil 60 during the rotation process; thus, the entire process of unwinding, coating, drying, cutting and winding of the foil 60 is automatically completed.

[0099] The above content is only a preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
