Description

Technical Field

[0001] This invention relates to the field of coating machine technology, specifically to a winding mechanism for a coating machine. Background Technology

[0002] Coating machines are key equipment used to uniformly and continuously coat the surface of flexible substrates (such as metal foil, plastic film, paper, and nonwoven fabric) with slurries of specific functions (such as lithium battery electrode slurries, photovoltaic backsheet slurries, adhesives, and optical film coatings). As the final stage of the coating process, the performance of the winding mechanism directly determines the quality of the final product (such as roll shape, tension uniformity, and surface quality) and production efficiency. The technological development goals of modern coating machine winding mechanisms are very clear: to achieve high-precision, high-stability, fully automated tension control, speed following, automatic web correction, contact pressure control, and seamless roll changing to adapt to increasingly higher coating speeds, wider web widths, thinner or more sensitive substrate coatings, and ever-increasing production efficiency and product quality requirements. This has driven the widespread application of servo drive technology, closed-loop tension sensors, high-precision web correction systems (EPC), air shafts, automatic roll changing systems (such as dual-station rotary tables, surface winding / center winding switching), and advanced control algorithms (such as PID, adaptive control, and taper tension models) in winding mechanisms.

[0003] Key operations such as roll changing and web correction rely on manual labor, which is inefficient. Frequent manual operations and long roll changing times restrict the improvement of the overall line speed. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a winding mechanism for a coating machine, comprising an equipment base, a main support fixedly connected to the top of the equipment base, a driving device fixedly connected to the top of the main support, a winding device fixedly connected to the side of the driving device, and a cutting device fixedly connected to the center of the side of the driving device.

[0005] The driving device includes a driving bracket, a movable gear rotatably connected to the side of the driving bracket via a rotating shaft, an internal gear ring meshing with the side of the movable gear, an external gear ring meshing with the side of the movable gear away from the internal gear ring, a driving gear meshing with the inner wall of the internal gear ring, a driving shaft of a first motor fixedly connected to the side of the driving gear, a fixed end of the first motor fixedly connected to the top of the main bracket via a bracket, and the bottom of the external gear ring fixedly connected to the top of the main bracket via a bracket.

[0006] Preferably, the winding device includes a second motor, a support assembly fixedly connected to the drive shaft of the second motor, a pressing assembly slidably connected to the side of the support assembly, a switching assembly fixedly connected to the side of the support assembly, a rotating assembly fixedly connected to the side of the switching assembly, a pressurizing assembly fixedly connected to the side of the support assembly via a bracket, a side of the second motor fixedly connected to the side of the moving gear, and a side of the pressurizing assembly fixedly connected to the side of the drive bracket.

[0007] Preferably, the support assembly includes a support rod with a limiting groove at its top. A first sliding strip is fixedly connected to the inner wall of the limiting groove, and a sliding hole is formed in the inner wall of the limiting groove. An oil storage groove is formed on the side of the support rod. The side of the support rod is fixedly connected to the drive shaft of a second motor and to the side of a pressure assembly. The core is sleeved on the side of the support rod and fixed by corresponding components. The first sliding strip restricts the sliding trajectory of the extrusion assembly, and the inner wall of the oil storage groove is pressurized by the switching assembly, thereby driving the extrusion assembly to slide along the side of the first sliding strip, thereby supporting the inner wall of the core and fixing the core, thus enabling quick replacement of the core and quick disassembly after winding.

[0008] Preferably, the extrusion assembly includes an extrusion block, a groove is provided on the side of the extrusion block, a guide groove is provided on the portion of the extrusion block located on one side of the groove, a movable rod is fixedly connected to the bottom of the extrusion block, a sliding tube is sleeved and slidably connected to the side of the movable rod, a limit ring is sleeved and fixedly connected to the bottom side of the sliding tube, the sliding tube is slidably connected to the support rod through a sliding hole, the limit ring is located in the portion inside the oil storage tank, and the extrusion block is slidably connected to the first sliding bar through the groove.

[0009] Preferably, the switching assembly includes a rotating seat, a connecting rod fixedly connected to the side of the rotating seat, a polygonal piston fixedly connected to the side of the connecting rod, a first spring fixedly connected to the side of the rotating seat located on one side of the connecting rod, a fixed seat fixedly connected to the end of the first spring away from the rotating seat, a first positioning groove formed on the side of the fixed seat near the rotating seat, a second positioning groove formed on the side of the fixed seat located on one side of the first positioning groove, a positioning rod adapted to the first positioning groove fixedly connected to the side of the rotating seat near the fixed seat, the side of the fixed seat fixedly connected to the side of the support rod, the polygonal piston being disposed on the inner wall of the oil storage tank and slidably connected to the support rod through the oil storage tank, rotating the rotating seat, the rotating seat causing the positioning rod to slide along the side of the fixed seat, the first positioning groove and the connecting rod being set at different depths, so that when the positioning rod contacts the first positioning groove and the second positioning groove, it pushes the polygonal piston under the action of the first spring. The polygonal piston has different depths inside the oil reservoir. When the positioning rod contacts the first positioning groove, the polygonal piston penetrates deeper into the oil reservoir, thereby pushing the hydraulic oil inside the oil reservoir into the sliding tube, driving the movable rod to move, which in turn drives the extrusion block to move, thus fixing the core. The trajectory of the extrusion block is fixed by the sliding groove, and the sliding range of the sliding tube is limited by the limiting ring. The guide groove facilitates the installation of the core. When the positioning rod contacts the second positioning groove, the rotating seat drives the connecting rod to move. The movement of the connecting rod causes the polygonal piston to exit the oil reservoir, thereby reducing the oil pressure inside the sliding tube. This allows the extrusion block to move along the same trajectory, thus releasing the inner wall of the core and enabling quick installation and disassembly of the core. The first spring is preset to be in a tensioned state, thus providing extrusion force to the inner wall of the core during the winding process, ensuring that the core does not slip during winding and improving winding efficiency.

[0010] Preferably, the rotating assembly includes a rotating base, a connecting seat rotatably connected to the side of the rotating base, a fixed shaft fixedly connected to the side of the connecting seat, a positioning strip sleeved and rotatably connected to the side of the fixed shaft, a torsion spring sleeved and slidably connected to the side of the fixed shaft, one end of the torsion spring being fixedly connected to the side of the positioning strip, and the end of the torsion spring away from the positioning strip being fixedly connected to the side of the connecting seat. A fixing groove is formed on the side of the positioning strip, and a magnet strip is fixedly connected to the inner wall of the fixing groove. A limiting hole adapted to the fixing groove is formed on the side of the rotating base, and the side of the rotating base is fixedly connected to the side of the rotating seat.

[0011] Preferably, the pressurizing assembly includes an electric slide table. A pressurizing rod is fixedly connected to the movable end of the electric slide table. A limiting plate is fixedly connected to the side of the pressurizing rod. The fixed end of the electric slide table is fixedly connected to the side of the drive bracket. When installing the core, multiple positioning strips approach the center of the side of the connecting seat under the action of the torsion spring, facilitating the core's installation through the side of the rotating base. After the core is installed, the positioning strips rotate along the fixed axis and are placed inside the limiting hole. The limiting hole and the fixed groove limit the positioning strips, thereby moving the rotating base. The rotating base then rotates the rotating seat, thus completing the pressurization and tightening of the core. The side of the positioning strip helps prevent the core from coming out, and the magnetic action of the magnetic strip and the limiting hole absorbs minor vibrations during winding, preventing accidental detachment. The electric slide table is activated, causing the pressurizing rod to move up and down, thus pressurizing the material and preventing uneven force from causing bending and affecting winding quality. The limiting plate restricts the material's position, thereby improving winding efficiency.

[0012] Preferably, the cutting device includes a fixing stud, a triangular arc-shaped blade fixedly connected to the side of the fixing stud, a threaded sleeve sleeved and threadedly connected to the side of the fixing stud away from the triangular arc-shaped blade, the fixing stud penetrating the side of the drive bracket and slidably connected to the drive bracket, the fixing stud being located at the center of the side of the drive bracket, the triangular arc-shaped blade being quickly disassembled through the cooperation of the fixing stud and the threaded sleeve, and the arc design of the triangular arc-shaped blade avoiding stress concentration during cutting, thereby preventing material curling problems caused by cutting, and thus improving winding efficiency.

[0013] This invention provides a winding mechanism for a coating machine. It has the following advantages:

[0014] 1. The winding mechanism of the coating machine is equipped with a first motor. The rotation of the first motor drives the drive gear to rotate, the rotation of the drive gear drives the inner gear ring to rotate, the rotation of the inner gear ring drives the moving gear to rotate, and the moving gear moves under the constraint of the drive bracket, thereby moving the moving gear along the inner wall of the outer gear ring, and thus moving the moving gear along the side of the drive bracket, thereby realizing the whole replacement, thereby realizing the rapid change of the core of the winding device and improving the winding efficiency.

[0015] 2. The winding mechanism of the coating machine is equipped with a support rod. The core is sleeved on the side of the support rod and fixed by a corresponding component. The first slide bar restricts the sliding trajectory of the extrusion component. By switching the component, pressure is applied to the inner wall of the oil storage tank, thereby driving the extrusion component to slide along the side of the first slide bar, thereby supporting the inner wall of the core and fixing the core, thus realizing the quick replacement of the core and quick disassembly after winding.

[0016] 3. The winding mechanism of the coating machine is equipped with a rotating seat. Rotating the rotating seat causes the positioning rod to slide along the side of the fixed seat. The first positioning groove and the connecting rod are set at different depths, so that when the positioning rod contacts the first and second positioning grooves, it pushes the polygonal piston to different depths inside the oil storage tank under the action of the first spring. When the positioning rod contacts the first positioning groove, the polygonal piston penetrates deeper into the oil storage tank, thereby pushing the hydraulic oil inside the oil storage tank into the sliding tube, driving the movable rod to move, which in turn drives the extrusion block to move, thus fixing the core and guiding the extrusion block along the track via the slide groove. The track is fixed, and the sliding range of the sliding tube is limited by the limiting ring. The guide groove is set to facilitate the installation of the core. When the positioning rod contacts the second positioning groove, the rotating seat drives the connecting rod to move. The movement of the connecting rod drives the polygonal piston to exit the interior of the oil storage tank, thereby reducing the oil pressure inside the sliding tube. This makes it easier for the extrusion block to move along the same track, thereby releasing the inner wall of the core and realizing the quick installation and disassembly of the core. In addition, the first spring is preset to the tension state, so that it always provides extrusion force to the inner wall of the core during the winding process, thereby ensuring that the core does not slip during winding and thus improving winding efficiency.

[0017] 4. The winding mechanism of this coating machine is equipped with a torsion spring. When installing the core, multiple positioning strips approach the center of the side of the connecting seat under the action of the torsion spring, making it easier for the core to pass through the side of the rotating base for installation. After the core is installed, the positioning strips rotate along the fixed shaft and are placed inside the limiting hole. The positioning strips are limited by the cooperation between the limiting hole and the fixed groove, thereby driving the rotating base to move. The rotating base drives the rotating seat to rotate, thereby completing the pressure and fastening of the core. The side of the positioning strip helps to prevent the core from coming out, and the magnetic effect of the magnetic strip and the limiting hole absorbs the slight vibration during winding, thus preventing accidental detachment. The electric slide is started, and the electric slide drives the pressure rod to move up and down, thereby pressurizing the material, thus avoiding uneven force that causes the material to bend and affect the winding quality. The limiting plate restricts the position of the material, thereby improving the winding efficiency.

[0018] 5. The winding mechanism of the coating machine is equipped with a triangular arc-shaped blade. The triangular arc-shaped blade can be quickly disassembled by the cooperation of the fixing stud and the screw sleeve. The arc design of the triangular arc-shaped blade avoids stress concentration during cutting, thereby preventing material curling during cutting and improving winding efficiency.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-2 The present invention provides a technical solution: a winding mechanism for a coating machine, including a base 1, a main support 2 fixedly connected to the top of the base 1, a driving device 3 fixedly connected to the top of the main support 2, a winding device 4 fixedly connected to the side of the driving device 3, and a cutting device 5 fixedly connected to the center of the side of the driving device 3.

[0031] The equipment base 1 provides overall support for the equipment, the main support 2 supports the drive device 3, the drive device 3 drives the winding device 4 to move, and the cutting device 5 cuts the material to facilitate winding. The drive device 3 drives the winding device 4 to move, so that it can be quickly replaced after winding, thereby greatly reducing the downtime caused by the unloading time after winding. The winding device 4 fixes the core, and the corresponding components of the winding device 4 realize the quick installation and removal of the core. The corresponding components of the winding device 4 realize continuous pressure on the material during winding, so as to facilitate winding and prevent serpentine winding caused by uneven force. The cutting device 5 cuts the material when the winding device 4 moves. The design of the cutting device 5 avoids stress concentration in the material, which would cause the material to twist during cutting.

[0032] The drive device 3 includes a drive bracket 301. A movable gear 302 is rotatably connected to the side of the drive bracket 301 via a rotating shaft. An internal gear ring 303 meshes with the side of the movable gear 302. An external gear ring 304 meshes with the side of the movable gear 302 away from the internal gear ring 303. A drive gear 305 meshes with the inner wall of the internal gear ring 303. The drive shaft of a first motor 306 is fixedly connected to the side of the drive gear 305. The fixed end of the first motor 306 is fixedly connected to the top of the main bracket 2 via a bracket. The bottom of the external gear ring 304 is fixedly connected to the top of the main bracket 2 via a bracket.

[0033] The first motor 306 is started, and the rotation of the first motor 306 drives the drive gear 305 to rotate. The rotation of the drive gear 305 drives the internal gear ring 303 to rotate. The rotation of the internal gear ring 303 drives the moving gear 302 to rotate. The moving gear 302 moves under the restriction of the drive bracket 301, so that the moving gear 302 moves along the inner wall of the outer gear ring 304, and so that the moving gear 302 moves along the side of the drive bracket 301, thereby realizing the whole replacement. This enables the winding device 4 to quickly change the core and improve the winding efficiency.

[0034] Please see Figures 1-4 The present invention provides a technical solution: the winding device 4 includes a second motor 402, a support component 403 is fixedly connected to the drive shaft of the second motor 402, a pressing component 404 is slidably connected to the side of the support component 403, a switching component 405 is fixedly connected to the side of the support component 403, a rotating component 406 is fixedly connected to the side of the switching component 405, a pressurizing component 407 is fixedly connected to the side of the support component 403 through a bracket, the side of the second motor 402 is fixedly connected to the side of the moving gear 302, and the side of the pressurizing component 407 is fixedly connected to the side of the drive bracket 301.

[0035] The support assembly 403 includes a support rod 4031. A limiting groove 4032 is formed on the top of the support rod 4031. A first sliding strip 4033 is fixedly connected to the inner wall side of the limiting groove 4032. A sliding hole 4034 is formed on the inner wall of the limiting groove 4032. An oil storage groove 4035 is formed on the side of the support rod 4031. The side of the support rod 4031 is fixedly connected to the drive shaft of the second motor 402. The side of the support rod 4031 is fixedly connected to the side of the pressurizing assembly 407.

[0036] The core is sleeved on the side of the support rod 4031 and fixed by corresponding components. The first slide bar 4033 restricts the sliding trajectory of the extrusion component 404, and the switching component 405 pressurizes the inner wall of the oil storage tank 4035, thereby driving the extrusion component 404 to slide along the side of the first slide bar 4033, thereby supporting the inner wall of the core and fixing the core, thus realizing the quick replacement of the core and quick disassembly after winding.

[0037] Please see Figures 1-6The present invention provides a technical solution: the extrusion assembly 404 includes an extrusion block 4041, a groove 4042 is provided on the side of the extrusion block 4041, a guide groove 4043 is provided on the part of the extrusion block 4041 located on one side of the groove 4042, a movable rod 4044 is fixedly connected to the bottom of the extrusion block 4041, a sliding tube 4045 is sleeved and slidably connected to the side of the movable rod 4044, a limit ring 4046 is sleeved and fixedly connected to the bottom of the side of the sliding tube 4045, the sliding tube 4045 is slidably connected to the support rod 4031 through a sliding hole 4034, the limit ring 4046 is located inside the oil storage tank 4035, and the extrusion block 4041 is slidably connected to the first sliding strip 4033 through the groove 4042.

[0038] The switching assembly 405 includes a rotating seat 4051, a connecting rod 4052 fixedly connected to the side of the rotating seat 4051, a polygonal piston 4053 fixedly connected to the side of the connecting rod 4052, a first spring 4054 fixedly connected to the side of the rotating seat 4051 located on one side of the connecting rod 4052, a fixed seat 4055 fixedly connected to the end of the first spring 4054 away from the rotating seat 4051, and a first positioning point provided on the side of the fixed seat 4055 near the rotating seat 4051. The second positioning groove 4057 is provided on the side of the fixed seat 4055 located on one side of the first positioning groove 4056. The rotating seat 4051 is fixedly connected to the side of the fixed seat 4055 with a positioning rod 4058 that is adapted to the first positioning groove 4056. The side of the fixed seat 4055 is fixedly connected to the side of the support rod 4031. The polygonal piston 4053 is disposed on the inner wall of the oil storage tank 4035 and is slidably connected to the support rod 4031 through the oil storage tank 4035.

[0039] Rotating the rotating seat 4051 causes the positioning rod 4058 to slide along the side of the fixed seat 4055. The first positioning groove 4056 and the connecting rod 4052 are set at different depths, so that when the positioning rod 4058 contacts the first positioning groove 4056 and the second positioning groove 4057, it pushes the polygonal piston 4053 to different depths within the inner wall of the oil storage tank 4035 under the action of the first spring 4054. When the positioning rod 4058 contacts the first positioning groove 4056, the polygonal piston 4053 penetrates deeper into the oil storage tank 4035, thereby pushing the hydraulic oil inside the oil storage tank 4035 into the sliding tube 4045, causing the movable rod 4044 to move, which in turn moves the extrusion block 4041, thus fixing the core and extruding it through the sliding groove 4042. The trajectory of the pressure block 4041 is fixed, and the sliding range of the sliding tube 4045 is limited by the limiting ring 4046. The guide groove 4043 facilitates the installation of the core. When the positioning rod 4058 contacts the second positioning groove 4057, the rotating seat 4051 drives the connecting rod 4052 to move. The movement of the connecting rod 4052 drives the polygonal piston 4053 to exit the oil storage tank 4035, thereby reducing the oil pressure inside the sliding tube 4045. This facilitates the movement of the pressure block 4041 along the same trajectory, thereby releasing the inner wall of the core and enabling quick installation and disassembly of the core. The first spring 4054 is preset in a tensioned state, thereby providing extrusion force to the inner wall of the core during the winding process, ensuring that the core does not slip during winding and improving winding efficiency.

[0040] Please see Figures 1-8 The present invention provides a technical solution: the rotating assembly 406 includes a rotating base 4061, a connecting seat 4062 rotatably connected to the side of the rotating base 4061, a fixed shaft 4063 fixedly connected to the side of the connecting seat 4062, a positioning strip 4064 sleeved and rotatably connected to the side of the fixed shaft 4063, a torsion spring 4065 sleeved and slidably connected to the side of the fixed shaft 4063, one end of the torsion spring 4065 fixedly connected to the side of the positioning strip 4064, and the end of the torsion spring 4065 away from the positioning strip 4064 fixedly connected to the side of the connecting seat 4062. A fixing groove 4066 is opened on the side of the positioning strip 4064, and a magnet strip 4067 is fixedly connected to the inner wall side of the fixing groove 4066. A limiting hole 4068 adapted to the fixing groove 4066 is opened on the side of the rotating base 4061, and the side of the rotating base 4061 is fixedly connected to the side of the rotating seat 4051.

[0041] The pressurizing assembly 407 includes an electric slide 4071, a pressurizing rod 4072 is fixedly connected to the movable end of the electric slide 4071, a limit plate 4073 is fixedly connected to the side of the pressurizing rod 4072, and the fixed end of the electric slide 4071 is fixedly connected to the side of the drive bracket 301.

[0042] During core installation, multiple positioning strips 4064 are positioned close to the side center of the connecting seat 4062 under the action of the torsion spring 4065, facilitating the core's passage through the side of the rotating base 4061 for installation. After the core is installed, the positioning strips 4064 rotate along the fixed shaft 4063 and are placed inside the limiting hole 4068. The limiting hole 4068 and the fixing groove 4066 limit the positioning strips 4064, thereby moving the rotating base 4061. 1. The rotating seat 4051 is driven to rotate, thereby pressing and securing the core. The side of the positioning strip 4064 helps to prevent the core from coming out. The magnetic action of the magnetic strip 4067 and the limiting hole 4068 absorbs the slight vibration during winding, thereby preventing accidental disengagement. The electric slide 4071 is activated, and the electric slide 4071 drives the pressure rod 4072 to move up and down, thereby pressing the material, thereby preventing uneven force from causing the material to bend and affecting the winding quality. The limiting plate 4073 restricts the position of the material, thereby improving the winding efficiency.

[0043] Please see Figures 1-9 The present invention provides a technical solution: the cutting device 5 includes a fixing stud 501, a triangular arc-shaped blade 502 is fixedly connected to the side of the fixing stud 501, a threaded sleeve 503 is sleeved and threadedly connected to the side of the fixing stud 501 away from the triangular arc-shaped blade 502, the fixing stud 501 passes through the side of the drive bracket 301 and is slidably connected to the drive bracket 301, and the fixing stud 501 is located at the center of the side of the drive bracket 301.

[0044] The triangular arc-shaped blade 502 is quickly disassembled by the cooperation of the fixed stud 501 and the threaded sleeve 503. The arc design of the triangular arc-shaped blade 502 avoids stress concentration during cutting, thereby preventing material curling during cutting and improving winding efficiency.
