Description

Technical Field

[0001] The invention belongs to the field of continuous film coating of coiled materials, and in particular relates to a coating interval adjustment mechanism, an adjustment method and a winding continuous film coating machine. Background Art

[0002] In the current coil continuous coating technology, the coating thickness is mainly controlled by adjusting the coating process parameters of the coating mechanism and the moving speed of the coil.

[0003] It takes a certain amount of time to adjust the coating process parameters of the coating mechanism to control the coating thickness, and the coating thickness cannot be quickly switched. Moreover, adjusting the coating process parameters will also bring about changes in other properties of the coating, which is not conducive to ensuring the consistency of the coating properties. The coating thickness is controlled by controlling the moving speed of the coil and then controlling the contact time between the coil and the coating chamber. When controlling the coating thickness of the coil, the moving speed of the coil will be limited, thereby affecting the coating efficiency of the coil. Moreover, when the continuous coating device for the coil is one of the processes of the coil processing line, it will affect the processing efficiency of other processes of the coil, making it difficult to achieve synchronous coordination.

[0004] Therefore, there is an urgent need for a coating thickness adjustment mechanism that can control the coating thickness without changing coating process parameters or the moving speed of the coil. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a coating interval adjustment mechanism, an adjustment method and a winding continuous coating machine which can control the coating thickness without changing the coating process parameters or the moving speed of the coil.

[0006] The present invention provides a coating interval adjustment mechanism, comprising a roller assembly and a shielding member;

[0007] The roller assembly comprises a self-rotating roller, and a telescopic mounting frame is disposed at each end of the self-rotating roller, one end of the telescopic mounting frame is rotatably connected to the self-rotating roller, and the other end is rotatably disposed at the axis of the coating roller;

[0008] A connecting cover which can rotate relative to the rotating roller body is arranged outside the rotating roller body, a groove is arranged on the connecting cover along the axial direction of the rotating roller body, and the roller surface of the rotating roller body protrudes from the groove;

[0009] One end of the shielding member is connected to the connecting cover, and the other end is connected to the inner wall of the coating chamber.

[0010] Furthermore, the telescopic mounting frame includes an elastic telescopic rod and rotating connecting members arranged at both ends of the elastic telescopic rod;

[0011] When the elastic telescopic rod is in an initial state, the distance between the axes of the two rotating connecting members is less than or equal to the sum of the radii of the coating roller and the rotating roller body.

[0012] Furthermore, both ends of the connection cover are rotatably connected to the telescopic mounting frame.

[0013] Furthermore, the shielding member is a telescopic rolling curtain, the main body of the telescopic rolling curtain is arranged on the inner wall of the coating chamber, and the movable end of the telescopic rolling curtain is fixedly arranged on the connecting cover.

[0014] Furthermore, the main body of the telescopic roller blind is slidably arranged on the inner wall of the coating chamber along the height direction.

[0015] Furthermore, the telescopic roller blind is a spring roller blind.

[0016] Furthermore, the shielding member is an elastic telescopic film.

[0017] The present invention also provides a roll-to-roll continuous coating machine, comprising a coating chamber, a coating roller, and two sets of the coating interval adjustment mechanisms described above;

[0018] A rectangular coating cavity is provided in the coating chamber, and an opening is provided above the rectangular coating cavity;

[0019] The coating roller is rotatably arranged above the rectangular coating cavity;

[0020] The two groups of coating interval adjustment mechanisms are symmetrically arranged on both sides of the coating roller, and the coating roller and the two connecting covers block the opening.

[0021] Furthermore, the roll-to-roll continuous coating machine also includes a unwinding roller, a winding roller and at least two guide rollers arranged outside the coating chamber. The coil to be coated on the unwinding roller passes through one of the guide rollers and adheres to the coating roller to enter the coating chamber, and then adheres to the coating roller to leave the coating chamber and is connected to the winding roller via another guide roller.

[0022] The present invention also provides a coating interval adjustment method, using the above-mentioned roll-to-roll continuous coating machine, comprising the following steps:

[0023] The arc surface of the coating roller between the two rotating roller bodies is the coating area, and the position of the rotating roller body in the circumferential direction of the coating roller is adjusted by the telescopic mounting frame to adjust the size of the coating area.

[0024] The beneficial effects of the present invention are that the coating interval adjustment mechanism provided by the present invention can, on the one hand, adjust the coating action interval of the coating chamber on the coil to be coated by adjusting the angle of the telescopic mounting frame. When the moving speed of the coil to be coated is consistent and the process of the coating mechanism in the coating chamber is consistent, the coating thickness on the coil to be coated can be adjusted by adjusting the coating action interval of the coating chamber on the coil to be coated; on the other hand, it can be used in conjunction with the coating roller as the upper wall of the coating chamber to prevent the coating material from being dissipated outside the coating chamber, thereby simplifying the structure of the coating chamber; on still another hand, the self-rotating roller body presses the coil to be coated against the coating roller, thereby improving the coordination stability between the coil to be coated and the coating roller.

For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, a physical connection, or a wireless communication connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0036] As shown in the accompanying drawings, the present invention provides a coating interval adjustment mechanism 1, which is used to adjust the action interval of the coating chamber 3 on the coil 8 to be coated, and includes a roller assembly 11 and a shielding member 12;

[0037] The roller assembly 11 includes a rotating roller body 111, and a telescopic mounting frame 112 is respectively arranged at both ends of the rotating roller body 111. One end of the two telescopic mounting frames 112 is rotatably connected to the rotating roller body 111, and the other end is rotatably arranged at the axis of the coating roller 2. This end can be arranged on the wall panel in the coating chamber 3, and can also be arranged on the rotating shaft of the coating chamber 3. Moreover, the rotation connection position between the telescopic mounting frame 112 and the axis of the coating roller 2 is also provided with a locking structure for locking and unlocking. When locked, the rotation connection between the telescopic mounting frame 112 and the axis of the coating roller 2 cannot continue to rotate, and the telescopic mounting frame 112 maintains the locking angle. When unlocked, the rotation connection between the telescopic mounting frame 112 and the axis of the coating roller 2 can rotate freely, and then the angle of the telescopic mounting frame 112 can be adjusted, that is, the rotating roller body 111 can rotate around its own axis, and can also rotate around the axis of the coating roller 2.

[0038] The rotating roller body 111 is provided with a connecting cover 113 that can rotate relative to the rotating roller body 111. The connecting cover 113 is provided with a slot 1131 along the axial direction of the rotating roller body 111. The roller surface of the rotating roller body 111 protrudes from the slot 1131. At this time, when the coil 8 to be coated is not installed, the roller surface of the rotating roller body 111 protrudes from the slot 1131 and can always roll with the coating roller 2. When the coil 8 to be coated is installed, the roller surface of the rotating roller body 111 can protrude from the slot 1131 and always fit with the coating roller 2. At this time, the rotating roller body 111 and the coating roller 2 are in a clamping state with the coating coil 8 to be coated.

[0039] One end of the shielding member 12 is connected to the connecting cover 113. Since the connecting cover 113 can rotate relative to the rotating roller body 111, when the coating roller 2 rotates to drive the to-be-coated coil 8 to move, although the to-be-coated coil 8 will drive the rotating roller body 111 to rotate, the shielding member 12 can always remain stationary, thereby ensuring the stability of its connection with the connecting cover 113 and avoiding winding of the connecting cover 113. The other end of the connecting cover 113 is connected to the inner wall of the coating chamber 3. In this way, the connecting cover 113, the rotating roller body 111 and the coating roller 2 form a seal to block the upper end opening 32 of the coating chamber 3, which is used as the upper end wall of the coating chamber 3 to avoid the coating material from being dissipated to the outside of the coating chamber 3. At this time, the coil 8 to be coated located outside the coating chamber 3 enters the coating chamber 3 from between the coating roller 2 and the rotating roller body 111 and adheres to the outer wall of the coating roller 2, and finally moves out of the coating chamber 3 from the other side of the coating roller 2. By adjusting the angle of the telescopic mounting frame 112, the range of the coil 8 to be coated exposed in the coating chamber 3 can be adjusted, thereby adjusting the coating action range of the coil 8 to be coated.

[0040] The coating interval adjustment mechanism 1 provided by the present invention, on the one hand, can adjust the coating range of the coating chamber 3 on the coil 8 to be coated by adjusting the angle of the telescopic mounting frame 112. When the moving speed of the coil 8 to be coated is consistent and the process of the coating mechanism 4 in the coating chamber 3 is consistent, the coating thickness on the coil 8 to be coated can be adjusted by adjusting the coating range of the coating chamber 3 on the coil 8 to be coated; on the other hand, it can be used in conjunction with the coating roller 2 as the upper wall of the coating chamber 3 to prevent the coating material from being scattered outside the coating chamber 3, thereby simplifying the structure of the coating chamber 3; on the other hand, the self-rotating roller body 111 presses the coil 8 to be coated against the coating roller 2, thereby improving the matching stability between the coil 8 to be coated and the coating roller 2.

[0041] In one embodiment, the telescopic mounting frame 112 includes an elastic telescopic rod 1121 and rotating connecting members 1122 arranged at both ends of the elastic telescopic rod 1121, and the elastic telescopic rod 1121 can realize the extension and retraction of two rotating connecting members 1122, and one of the rotating connecting members 1122 is used for rotationally connecting to the rotating roller body 111, and the other rotating connecting member 1122 is used for rotationally connecting to the axis of the coating roller 2;

[0042] In the initial state of the elastic telescopic rod 1121, the axial distance between the two rotating connecting members 1122 is less than or equal to the sum of the radii of the coating roller 2 and the rotating roller body 111, that is, in the initial state, the elastic telescopic rod 1121 makes the rotating roller body 111 fit the coating roller 2 or the coil 8 to be coated. When the coil 8 to be coated needs to be installed on the rotating roller body 111 and the coating roller 2, it is only necessary to stretch the elastic telescopic rod 1121 to form a gap between the rotating roller body 111 and the coating roller 2, and then insert the coil 8 to be coated into the gap between the rotating roller body 111 and the coating roller 2, and finally release the elastic telescopic rod 1121, and the elastic telescopic rod 1121 is reset, so that the rotating roller body 111 presses the coil 8 to be coated tightly against the coating roller 2. In addition, the provision of the elastic telescopic rod 1121 can also enable the coating interval adjustment mechanism 1 to adapt to coating rollers 2 of different sizes, thereby improving the adaptability of the mechanism. Such an arrangement can avoid the formation of a gap between the rotating roller body 111 and the coating roller 2 , which would cause the coating material to be scattered outside the coating chamber 3 .

[0043] In one embodiment, both ends of the connection cover 113 are rotatably connected to the telescopic mounting frame 112 to simplify the installation of the connection cover 113 . In other embodiments, the connection cover 113 can be directly rotatably set on the rotating roller body 111 .

[0044] In one embodiment, the shielding member 12 is a telescopic roller blind, the main body 121 of the telescopic roller blind is arranged on the inner wall of the coating chamber 3, and the movable end of the roller blind 122 of the telescopic roller blind is fixedly arranged on the connecting cover 113. In this way, when the rotating roller body 111 rotates along the coating roller 2, the roller blind 122 can be retracted synchronously to ensure that the shielding member 12 is always connected to the rotating roller body 111 and the inner wall of the coating chamber 3. The main body 121 of the telescopic roller blind is arranged on the inner wall of the coating chamber 3, which can simplify the installation difficulty of the main body 121. The roller blind 122 in this embodiment preferably adopts a high temperature resistant film structure.

[0045] In one of the embodiments, the main body 121 of the retractable roller shutter is slidably arranged on the inner wall of the coating chamber 3 along the height direction. By so arranging, the height of the roller shutter 122 connected to the inner wall of the coating chamber 3 can be adjusted, so that the roller shutter 122 can be in an inclined state, and the coating material generated by the coating mechanism 4 can flow to the coating area of ​​the coil 8 to be coated. In this embodiment, a locking and unlocking structure is provided at the sliding part of the main body 121, so that the position of the main body 121 of the retractable roller shutter can be fixed.

[0046] In one embodiment, the telescopic roller blind is a spring roller blind that uses a coiled spring and does not require an electric drive component. The telescopic roller blind can adaptively adjust the position of the rotating roller body 111 and the height of the main body 121 of the telescopic roller blind.

[0047] In the embodiment where the shielding member 12 is not a telescopic roller blind, the shielding member 12 is an elastic telescopic film, which adapts to the position adjustment of the rotating roller body 111 with its elasticity.

[0048] The present invention also provides a roll-to-roll continuous coating machine, comprising a coating chamber 3, a coating roller 2, and two sets of the above-mentioned coating interval adjustment mechanisms 1;

[0049] A rectangular coating cavity 31 is provided in the coating chamber 3, an opening 32 is provided above the rectangular coating cavity 31, and a coating mechanism 4 is provided at the bottom of the coating chamber 3;

[0050] The coating roller 2 is rotatably disposed above the rectangular coating cavity 31;

[0051] The two groups of coating interval adjustment mechanisms 1 are symmetrically arranged on both sides of the coating roller 2 , and the coating roller 2 and the two connecting covers 113 block the opening 32 .

[0052] The coil 8 to be coated passes between the coating roller 2 and one of the rotating roller bodies 111 into the coating chamber 3, and leaves the coating chamber 3 along the outer wall of the coating roller 2 through between the coating roller 2 and the other rotating roller body 111. The coil 8 to be coated keeps moving, so that continuous coating of the coil 8 to be coated can be achieved. At this time, by adjusting the distance between the two rotating roller bodies 111, the coating interval of the coil 8 to be coated exposed to the coating chamber 3 at a certain moment can be adjusted.

[0053] In one embodiment, the coating mechanism 4 may be an evaporation mechanism, a magnetron sputtering mechanism or an ion coating mechanism.

[0054] Preferably, the side wall of the coating chamber 3 is a double-layer side wall, and an installation cavity is formed between the two side walls. An arc groove 33 is arranged on the inner wall, and the telescopic mounting frame 112 is arranged on the outer side of the side wall of the coating chamber 3, and the rotating shaft of the rotating roller body 111 passes through the arc groove 33 and is rotatably connected with the telescopic mounting frame 112. The inner wall of the coating chamber 3 is also provided with a vertical groove 34, and the main body 121 of the telescopic roller shutter is slidably set on the vertical groove 34, while the outer wall is detachably set on the coating chamber 3, so that the staff can adjust the positions of the rotating roller body 111 and the main body 121 of the telescopic roller shutter through the arc groove 33 and the vertical groove 34.

[0055] In one embodiment, the roll-to-roll continuous coating machine further includes an unwinding roller 5, a winding roller 6 and at least two guide rollers 7 arranged outside the coating chamber 3. The coil 8 to be coated on the unwinding roller 5 passes through one of the guide rollers 7 and then adheres to the coating roller 2 to enter the coating chamber 3. Then, it adheres to the coating roller 2 and leaves the coating chamber 3 and is connected to the winding roller 6 through another guide roller 7. Of course, other supporting equipment, such as an optical fiber monitoring module, a plasma processor, etc., can also be arranged at the path of the coil 8 to be coated outside the coating chamber 3. In this embodiment, the coil 8 to be coated is on the unwinding roller 5, and after being guided by the guide roller 7, it passes through the coating roller 2 to enter the coating chamber 3 for coating, and then passes through the guide roller 7 after leaving the coating chamber 3 and enters the winding roller 6 for winding.

[0056] In one embodiment, the coiled material 8 to be coated can be a paper roll, a cloth roll, a plastic roll, a metal roll, a flexible ultra-thin glass, etc.

[0057] The present invention also provides a coating interval adjustment method, using the above-mentioned roll-to-roll continuous coating machine, comprising the following steps:

[0058] The arc surface of the coating roller 2 between the two rotating roller bodies 111 is the coating area. The position of the rotating roller body 111 in the circumferential direction of the coating roller 2 is adjusted by the telescopic mounting frame 112 to adjust the size of the coating area.
