[0034] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0035] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0036] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0037] The coiling and pressing device 100 for a foil production machine according to an embodiment of the present utility model will be described in detail below with reference to the accompanying drawings.

[0038] like Figures 1 to 5 As shown, the foil rolling and pressing device 100 of the foil raw machine according to the embodiment of the utility model includes: a frame 10, a winding roller 20, an angle adjustment mechanism 30, a limiter 40 and a pressing roller 50.

[0039] Specifically, the winding roller 20 is rotatably arranged on the frame 10 around its own axis, and the winding roller 20 is suitable for winding foil. The angle adjustment mechanism 30 includes a rotating shaft 31 and a first swing arm 32. The rotating shaft 31 is rotatably arranged on the frame 10 around its own axis, and the axis of the rotating shaft 31 is parallel to the axis of the winding roller 20. The first swing arm 32 is connected to the rotating shaft 31 and extends along the radial direction of the rotating shaft 31. The limiter 40 is arranged on the first swing arm 32, and a limit track 41 is provided on the limiter 40, and the extension direction of the limit track 41 intersects with the axial direction of the winding roller 20. The axis of the pressure roller 50 is parallel to the axis of the winding roller 20, and both ends of the pressure roller 50 are slidably connected to the limit track 41.

[0040] In other words, the foil machine rolling and pressing device 100 according to the embodiment of the utility model is mainly composed of a frame 10, a winding roller 20, an angle adjustment mechanism 30, a stopper 40 and a pressing roller 50. The foil material generated by the foil machine can be rolled and pressed by the foil machine rolling and pressing device 100.

[0041] Specifically, a winding roller 20 may be provided on the frame 10 , and the winding roller 20 may rotate around its own axis. The foil material generated by the foil production machine may be wound up by the winding roller 20 , and the foil material may be wound around the outer peripheral surface of the winding roller 20 .

[0042] The frame 10 is also provided with an angle adjustment mechanism 30, which can be mainly composed of a rotating shaft 31 and a first swing arm 32. The axis of the rotating shaft 31 can be parallel to the axis of the winding roller 20, and the rotating shaft 31 rotates around its own axis. The first swing arm 32 and the second swing arm 33 are respectively in the shape of long strips, and the first swing arm 32 and the second swing arm 33 can extend along the radial direction of the rotating shaft 31.

[0043] The first swing arm 32 may be connected to the rotating shaft 31 and rotate around the axis of the rotating shaft 31 under the drive of the rotating shaft 31. The first swing arm 32 may extend along the radial direction of the rotating shaft 31. A stopper 40 may be provided on the first swing arm 32.

[0044] That is, the angle adjustment mechanism 30 can rotate around the axis of the rotating shaft 31 relative to the frame 10 , so the axis of the rotating shaft 31 does not coincide with the axis of the winding roller 20 .

[0045] A pressure roller 50 is rotatably mounted on the angle adjustment mechanism 30, and the axis of the pressure roller 50 can be parallel to the axis of the winding roller 20. When the angle adjustment mechanism 30 rotates around the axis of the rotating shaft 31, the pressure roller 50 can also rotate around the axis of the rotating shaft 31. Since the axis of the rotating shaft 31 is parallel to the axis of the winding roller 20, the angle between the pressure roller 50 and the winding roller 20 can be adjusted when the rotating shaft 31 rotates. The angle between the pressure roller 50 and the winding roller 20 can be the angle between the shortest line between the axis of the pressure roller 50 and the axis of the winding roller 20 and the horizontal line.

[0046] In addition, the angle adjustment mechanism 30 and the pressure roller 50 may be connected via a limit member 40 . The limit member 40 may be mounted on the first swing arm 32 . When the angle adjustment mechanism 30 rotates around the axis of the rotating shaft 31 , the limit member 40 may also rotate around the axis of the rotating shaft 31 .

[0047] Optionally, the first swing arm 32 may have two ends, namely a first end and a second end. One end of the first swing arm 32 may be connected to the rotating shaft 31. The connection here may include but is not limited to a fixed connection and a movable connection, which are not limited here. A limit member 40 may be installed at the second end of the first swing arm 32. Optionally, the limit member 40 may be integrally formed on the first swing arm 32 or may be detachably installed on the first swing arm 32.

[0048] A limiting track 41 may be provided on the limiting member 40, and the number of the limiting track 41 may be two. The two limiting tracks 41 may be spaced apart along the axis of the pressure roller 50, and both ends of the pressure roller 50 may be rotatably provided on the limiting track 41, and the pressure roller 50 may slide along the limiting track 41, and the extension direction of the limiting track 41 may intersect with the axial direction of the winding roller 20, thereby, the pressure roller 50 may approach or move away from the winding roller 20 while sliding along the limiting track 41.

[0049] The two ends of the limiting track 41 are closed ends, and the two closed ends can respectively limit the pressure roller 50. In some optional embodiments, the two closed ends of the limiting track 41 are spaced apart in the vertical direction, and the lower closed end can limit the lowest position of the pressure roller 50, and the upper closed end can limit the highest position of the pressure roller 50.

[0050] During the process of rolling up the foil material by the rolling and pressing device 100 of the raw foil machine, the rotating shaft 31 rotates around its own axis, so that the limiter 40 and the pressure roller 50 can be moved closer to or away from the winding roller along a specific arc track, thereby adjusting the angle between the pressure roller 50 and the winding roller 20 to adjust the pressure of the pressure roller 50 on the foil material, and realize controllable adjustment of the pressure. In addition, the pressure roller 50 can be movable along the limit track 41 of the limiter 40, so that the pressure of the pressure roller 50 on the foil material can be the component of the weight of the pressure roller 50 itself, so as to avoid excessive pressure to damage the foil material, or too little pressure to cause the foil material to loosen and deform.

[0051] Therefore, according to the foil machine winding and pressing device 100 of this embodiment, an angle adjustment structure is arranged on the frame 10, and the angle between the pressing roller 50 and the winding roller 20 can be controlled by utilizing the cooperation of the rotating shaft 31 and the first swing arm 32 and according to the winding situation of the winding roller 20, and a limit member 40 is arranged on the angle adjustment mechanism 30, so that the pressing roller 50 can slide along the limit track 41 on the limit member 40, so that the gravity of the pressing roller 50 itself can be utilized to press the winding roller 20 or the foil on the winding roller 20, and the angle of the pressing roller 50 can be adjusted to control the pressure of the pressing roller 50 within a suitable range, which can avoid the pressure of the pressing roller 50 being too high to cause damage to the foil, and can also avoid the pressure of the pressing roller 50 being too low to cause loose deformation of the material roll, and the operation is safe and quick, which is conducive to improving the stability of winding.

[0052] In some optional embodiments, the rotating shaft 31 may be driven by a motor.

[0053] According to a specific embodiment of the utility model, the angle adjustment mechanism 30 is rotatably arranged on the frame 10 between a first state and a second state around the axis of the rotating shaft 31. When the angle adjustment mechanism 30 is in the first state, the pressure roller 50 is separated from the winding roller 20. When the angle adjustment mechanism 30 is in the second state, the pressure roller 50 abuts against the winding roller 20 under its own weight.

[0054] Specifically, during the rotation of the angle adjustment mechanism 30, the angle adjustment mechanism 30 can switch between the first state and the second state. When the angle adjustment mechanism 30 is in the first state, the stopper 40 is away from the winding roller 20, and the pressure roller 50 is away from the winding roller 20, and the pressure roller 50 and the winding roller 20 or the foil rolled on the winding roller 20 can be spaced apart, and the foil on the winding roller 20 can be unloaded or the winding roller 20 can be replaced.

[0055] When the angle adjustment mechanism 30 is in the second state, the limiting member 40 is close to the winding roller 20, so that the pressure roller 50 is close to the winding roller 20, and the pressure roller 50 can abut against the outer peripheral surface of the winding roller 20 or the foil on the winding roller 20, and the pressure roller 50 is not limited by the end of the limiting track 41. Therefore, the pressure roller 50 can press the winding roller 20 or the foil on the winding roller 20 under the action of its own gravity.

[0056] For the sake of convenience, the rotation direction of the angle adjustment mechanism 30 when switching from the first state to the second state can be defined as a forward direction, and the rotation direction of the angle adjustment mechanism 30 when switching from the second state to the first state can be defined as a reverse direction.

[0057] When the angle adjustment mechanism 30 rotates forward, the pressure roller 50 approaches the winding roller 20 and gradually lowers its height, and the movement trajectory of the pressure roller 50 is arc-shaped, the center of the arc coincides with the axis of the rotating shaft 31, and the angle between the pressure roller 50 and the winding roller 20 becomes smaller and smaller.

[0058] It should be noted that the pressure applied by the pressure roller 50 on the winding roller 20 or the foil on the winding roller 20 is the component of the weight of the pressure roller 50 itself. The larger the angle between the pressure roller 50 and the winding roller 20, the larger the component of the weight of the pressure roller 50 itself in the direction of the line connecting the pressure roller 50 and the winding roller 20, and therefore, the greater the pressure applied by the pressure roller 50 on the winding roller 20 or the foil on the winding roller 20.

[0059] When the foil on the winding roller 20 increases, the diameter of the foil roll becomes larger and larger, and a greater pressure is needed to compact the foil. At this time, the angle adjustment mechanism 30 can be gradually switched from the second state to the first state, so that the angle between the pressure-changing roller 50 and the winding roller 20 increases, thereby increasing the pressure of the pressure roller 50 on the foil.

[0060] In addition, by switching the angle adjustment mechanism 30 between the first state and the second state, the pressing roller 50 can be quickly lifted and pressed down, thereby improving the convenience and safety of operation.

[0061] According to an embodiment of the present invention, the axis of the pressure roller 50 is higher than the axis of the winding roller 20. Specifically, when the angle adjustment mechanism 30 drives the pressure roller 50 to rotate to any position that the pressure roller 50 can reach, the axis of the pressure roller 50 can be higher than the axis of the winding roller 20, so that when the pressure roller 50 abuts against the winding roller 20, it is ensured that the gravity of the pressure roller 50 can have a non-zero component in the direction of the line connecting the pressure roller 50 and the winding roller 20, so that there is always an interactive pressure between the pressure roller 50 and the winding roller 20.

[0062] According to some other embodiments of the present invention, the angle adjustment mechanism 30 further includes a second swing arm 33. The second swing arm 33 extends radially along the rotating shaft 31, one end of the second swing arm 33 is connected to the end of the rotating shaft 31, and the other end of the second swing arm 33 is formed as a toggle end.

[0063] Specifically, the second swing arm 33 can have two ends, namely a first end and a second end. One end of the second swing arm 33 can be fixedly connected to the rotating shaft 31, and the second end of the second swing arm 33 can be formed as a toggle end. By toggling the toggle end with external force, the rotating shaft 31 can be driven to rotate around its own axis, thereby driving the first swing arm 32, the limit member 40 and the pressure roller 50 to rotate around the axis of the rotating shaft 31.

[0064] The toggle end can be toggled manually or mechanically, which is not limited here. The mechanical drive may include but is not limited to motor drive and cylinder drive.

[0065] When the foil on the winding roller 20 gradually increases, the pressure roller 50 is lifted up along with the increase of the foil. During the lifting of the pressure roller 50 , the rotating shaft 31 , the first swing arm 32 and the second swing arm 33 can rotate in opposite directions.

[0066] In addition, the first swing arm 32 and the second swing arm 33 may be connected to the ends of the rotating shaft 31 , and in the axial direction of the rotating shaft 31 , the first swing arm 32 and the second swing arm 33 may be spaced apart.

[0067] Optionally, a bearing seat 11 may be provided on the frame 10 , and the end of the rotating shaft 31 may be rotatably mounted on the bearing seat 11 . The bearing seat 11 may be located between the first swing arm 32 and the second swing arm 33 .

[0068] In this embodiment, the rotating shaft 31, the first swing arm 32 and the second swing arm 33 can be connected to form a connecting rod assembly, and by toggling the toggling end of the second swing arm 33, the first swing arm 32, the second swing arm 33, the rotating shaft 31, the stopper 40 and the pressure roller 50 can be driven to rotate around the rotating shaft 31 to adjust the angle between the pressure roller 50 and the winding shaft. The connecting rod assembly has the advantages of simple structure and high reliability, and the angle of the pressure roller 50 can be adjusted steplessly.

[0069] In some specific embodiments of the present invention, the angle adjustment mechanism 30 also includes a driving member 34, which is disposed on the frame 10 and connected to the toggle end to drive the second swing arm 33, the rotating shaft 31 and the first swing arm 32 to rotate around the axis of the rotating shaft 31.

[0070] In this embodiment, the toggle end can be toggled by a driving member 34, and the driving member 34 includes but is not limited to a linear motor, a cylinder, and a hydraulic cylinder. The driving member 34 is provided to drive the toggle end, so that the angle of the pressure roller 50 can be electrically adjusted, thereby adjusting the angle of the pressure roller 50 more quickly according to needs, with higher safety and convenience.

[0071] According to some optional embodiments of the utility model, the first swing arm 32 is rotatably connected to the rotating shaft 31, the rotating shaft 31 is provided with a first limit block 311, the first swing arm 32 is provided with a second limit block 321, and the second limit block 321 is located above the first limit block 311 and abuts against the first limit block 311.

[0072] Specifically, the first swing arm 32 is rotatable relative to the rotating shaft 31 around the axis of the rotating shaft 31. A first limit block 311 may be fixedly connected to the rotating shaft 31, and a second limit block 321 may be fixedly connected to the first swing arm 32. The first limit block 311 may abut against the first limit block 311, so that the first swing arm 32 is limited. At this time, the first limit block 311 may be located below the second limit block 321. In the direction from the first end of the first swing arm 32 to the second end, the first swing arm 32 may extend obliquely upward. The first swing arm 32 may be located above the winding roller 20, and the second swing arm 33 may drive the first swing arm 32 to rotate in the positive direction through the rotating shaft 31.

[0073] In addition, a first limit block 311 is provided to abut against a second limit block 321. When the rotating shaft 31 is kept fixed, the first swing arm 32 can still rotate in the opposite direction. Therefore, the pressure roller 50 can be separated from the winding roller 20 by lifting the first swing arm 32 alone. This increases the angle adjustment method of the pressure roller 50 and helps to improve the convenience of operation.

[0074] According to some other embodiments of the utility model, the number of the first swing arms 32 and the second swing arms 33 is two, the two first swing arms 32 are connected to the two ends of the rotating shaft 31, the two second swing arms 33 are connected to the two ends of the rotating shaft 31, a connecting column 35 is connected between the ends of the two first swing arms 32 away from the rotating shaft 31, and each first swing arm 32 is connected to a limiting member 40.

[0075] Specifically, each end of the rotating shaft 31 may be connected to a first swing arm 32 and a second swing arm 33. The two first swing arms 32 and the two second swing arms 33 may be spaced apart along the axis of the rotating shaft 31. Providing the two first swing arms 32 and the two second swing arms 33 is conducive to improving the stability of the angle adjustment mechanism 30.

[0076] In addition, a connecting column 35 may be connected between the second ends of the two first swing arms 32 . The connecting column 35 may extend along the axial direction of the rotating shaft 31 . The connecting column 35 may play a reinforcing role, making the second ends of the two first swing arms 32 more stable.

[0077] In addition, the second ends of the two first swing arms 32 are respectively connected to the limiting members 40 , thereby the two limiting members 40 can be spaced apart along the axial direction of the pressure roller 50 , making it convenient for the two ends of the pressure roller 50 to be connected to the limiting tracks 41 on the limiting members 40 .

[0078] In some specific embodiments of the present invention, the raw foil machine winding and pressing device 100 also includes a limiting mechanism 60, which is arranged on the frame 10 and located below the first swing arm 32. When the angle adjustment mechanism 30 is in the first state, the limiting mechanism 60 releases the limitation on the first swing arm 32. When the angle adjustment mechanism 30 is in the second state, the limiting mechanism 60 limits the first swing arm 32.

[0079] Specifically, a limiting mechanism 60 may be provided on the frame 10 , and the limiting mechanism 60 may be located below the first swing arm 32 .

[0080] like Figure 3 As shown, when the angle adjustment mechanism 30 is in the first state, the limiting mechanism 60 can be separated from the first swing arm 32, and the first swing arm 32 can freely drive the pressure roller 50 to approach the winding shaft.

[0081] like Figure 4 As shown, when the angle adjustment mechanism 30 is in the second state, the limiting mechanism 60 can limit the limit position of the first swing arm 32, thereby limiting the minimum angle between the pressing roller 50 and the winding roller 20. In other words, when the first swing arm 32 rotates in the positive direction to the limit position, the first swing arm 32 can be limited by the limiting mechanism 60.

[0082] In this embodiment, the limiting mechanism 60 is used to limit the first swing arm 32 when the angle adjustment mechanism 30 is in the second state, so as to prevent the axis of the pressure roller 50 from being lower than the axis of the winding shaft, so that the pressure roller 50 can always apply pressure to the winding roller 20 or the foil on the winding roller 20.

[0083] According to some optional embodiments of the utility model, the limiting mechanism 60 includes a limiting rod 61, which extends toward the first swing arm 32. The limiting rod 61 is retractable along its own extension direction. When the angle adjustment mechanism 30 is in the first state, the limiting rod 61 is spaced apart from the first swing arm 32. When the angle adjustment mechanism 30 is in the second state, the limiting rod 61 abuts against the first swing arm 32.

[0084] Specifically, the limiting mechanism 60 may include a retractable limiting rod 61, and the limiting rod 61 may extend toward the first swing arm 32. When the end of the limiting rod 61 abuts against the first swing arm 32, the limiting rod 61 may limit the first swing arm 32, so that the limit position of the first swing arm 32 may be adjusted by adjusting the position of the limiting rod 61, thereby controlling the minimum angle between the pressing roller 50 and the winding roller 20.

[0085] In some optional embodiments, the limiting mechanism 60 may further include a limiting driving structure, which can drive the telescopic rod to extend and retract. As a result, the position of the telescopic rod can be automatically controlled according to demand, thereby achieving adjustment of the angle of the pressure roller 50, increasing the angle adjustment method of the pressure roller 50 and making the operation more flexible.

[0086] According to some other embodiments of the present invention, the limiting member 40 is rotatably connected to the angle adjustment mechanism around a second preset axis, and the second preset axis is parallel to the axis of the winding roller 20 .

[0087] Specifically, the limit member 40 can rotate relative to the angle adjustment mechanism, and the axis of rotation of the limit member 40 can be a second preset axis parallel to the axis of the winding roller 20. For example, the limit member 40 can be rotatably connected to the second end of the first swing arm 32. Thus, the angle between the pressure roller 50 and the winding roller 20 can be adjusted by rotating the limit member 40, which increases the angle adjustment method and makes the operation more flexible.

[0088] In some specific embodiments of the present utility model, one of the angle adjustment mechanism 30 and the limiting member 40 is provided with an arc-shaped waist-shaped hole 71, and the waist-shaped hole 71 is arranged around the second preset axis. The other of the angle adjustment mechanism 30 and the limiting member 40 is provided with a connecting hole. A positioning pin 72 and a bolt 73 are connected between the angle adjustment mechanism 30 and the limiting member 40. The positioning pin 72 extends along the second preset axis. The limiting member 40 can rotate around the positioning pin 72. The bolt 73 connects the waist-shaped hole 71 and the connecting hole to fasten the angle adjustment mechanism 30 and the limiting member 40.

[0089] Specifically, the angle adjustment mechanism 30 and the limiting member 40 may be positioned and connected via a positioning pin 72 . The positioning pin 72 may rotate along the second preset axis. Therefore, the limiting member 40 may rotate around the positioning pin 72 .

[0090] The configuration of the waist-shaped hole 71 and the connecting hole may include but is not limited to the following situations:

[0091] In case 1, the angle adjustment mechanism 30 is provided with a waist-shaped hole 71, and the limiting member 40 is provided with a connecting hole;

[0092] In case 2, a connecting hole is provided on the angle adjustment mechanism 30 , and a waist-shaped hole 71 is provided on the limiting member 40 .

[0093] The waist-shaped hole 71 may be arc-shaped, and the waist-shaped hole 71 may be arranged around the outer circumference of the pin. The waist-shaped hole 71 and the connecting hole may be fixedly connected by a bolt 73. Specifically, after the limiter 40 is rotated to a specific position according to the requirements, the limiter 40 may be locked at the position by the bolt 73 cooperating with the waist-shaped hole 71.

[0094] Optionally, the number of the waist-shaped holes 71 may be equal to the number of the connecting holes, and the number of the waist-shaped holes 71 may be multiple, so as to improve the reliability of the connection between the stopper 40 and the angle adjustment mechanism 30. For example, the number of the waist-shaped holes 71 on each angle adjustment mechanism 30 or the stopper 40 may be four, and the four waist-shaped holes 71 may surround the outer peripheral side of the positioning pin 72.

[0095] In some optional embodiments, an adjustment block 42 is provided on the limiting member 40 , and the adjustment block 42 is used to adjust the horizontal pitch between the pressing roller 50 and the winding roller 20 .

[0096] The installation process of the foil production machine winding and pressing device 100 of this embodiment is described in detail below.

[0097] Install the two first swing arms 32 onto the rotating shaft 31, and fix the two first swing arms 32 through the connecting column 35, install the rotating shaft 31 onto the frame 10 through the bearing seat 11, install the second swing arms 33 at both ends of the rotating shaft 31, and connect the driving member 34 to the second swing arm 33 through the fisheye joint. Install the limiting frame onto the first swing arm 32 through the positioning pin 72, and adjust the angle of the limiting member 40 through the waist hole 71 and the bolt 73. Install the first limiting block 311 onto the rotating shaft 31, install the second limiting block 321 onto the first swing arm 32, so that the first swing arm 32 is limited by the first limiting block 311, and install the limiting mechanism 60 onto the frame 10. Install the pressure roller 50 into the limiting track 41 of the two limiting members 40, and adjust the horizontal pitch between the pressure roller 50 and the winding roller 20 through the adjusting block 42.

[0098] In summary, the foil machine winding and pressing device 100 of this embodiment can quickly lift the pressing roller 50 through the driving member 34, thereby avoiding manual operation and reducing risks; and multiple adjustments are set, the pressing roller 50 completely presses the material by its own weight, and can achieve a variety of pressure pressing methods by adjusting the angle of the limiting track 41, thereby ensuring stable winding.
