Description

Technical Field

[0001] The invention relates to the technical field of winding devices, in particular to a winding device for rewinding aluminum foil. Background Art

[0002] The aluminum foil winding device is a device used to roll aluminum foil into a roll. Aluminum foil needs to go through multiple processes in the production process, such as coating, printing, and lamination. These processes may cause the surface of the aluminum foil to be uneven, loose, and have bubbles, and may also introduce some impurities or pollutants. Therefore, in order to ensure the quality and appearance of the aluminum foil and facilitate subsequent processing and use, the aluminum foil needs to be rewound. One end of the aluminum foil is fixed on the surface of the winding roller, and the aluminum foil is rolled into a roll by driving the winding roller to rotate.

[0003] The rewinding process of aluminum foil is to pull out one end of the aluminum foil, fix it on the rewinding roller of the rewinding device, and rewind it by rotating the rewinding roller.

[0004] A Chinese patent with publication number CN112093527B discloses an aluminum foil winding device with adjustable tightening degree, which can clamp winding drums of different diameters, so that the aluminum foil can be wound onto winding drums of different models; by adjusting the position of the movable disk, winding drums of different lengths can be mounted on the power shaft to wind the aluminum foil, thereby meeting the needs of winding aluminum foils of different widths.

[0005] A Chinese patent with publication number CN115649918A discloses an electrochemical aluminum foil coating and winding device, which can make a pressure roller press against the electrochemical aluminum foil wound by a paper roll, so that the electrochemical aluminum foil is not easy to become loose during the winding process, and the electrochemical aluminum foil after winding is more compact and has neater edges.

[0006] First, the above-mentioned and similar prior arts are difficult to ensure that the diameter of the aluminum foil after winding remains consistent when using a winding device for winding; secondly, in order to keep the diameter of the aluminum foil after winding consistent, the prior art generally needs to set a sensor on the winding device to detect the winding diameter, and the sensor may be affected by environmental factors such as dust, grease or other pollutants. In this way, when the winding diameter reaches the preset stop size, the sensor may not be able to accurately identify it, resulting in errors or misjudgments, and the winding device either stops too early or delays stopping, thereby affecting production efficiency. In addition, the sensor itself is in an environment of dust, grease or other pollutants, which will cause the risk of malfunction or even failure. When the sensor is damaged or fails, the device may not be able to stop working in time, resulting in more serious consequences, causing the winding diameter to exceed the design range, which may damage the rolled aluminum foil at the least, or squeeze the winding roller and cause damage to the entire winding device at the worst.

[0019] Beneficial effects of the present invention:

[0020] (1) The winding device for aluminum foil rewinding described in the present invention adopts the design of a power mechanism and a winding assembly. The meshing of a large gear and a small gear drives the winding roller to rewind the aluminum foil. As the radius of the aluminum foil roll increases, the large gear and the small gear are pushed away from each other. When the radius of the aluminum foil roll increases to be greater than the sum of the radii of the small gear and the large gear, the two no longer mesh. At this time, the winding roller loses the rotational force provided by the small gear and does not rotate due to the surface friction between the aluminum foil roll and the sleeve, thereby automatically stopping the winding.

[0021] (2) The winding device for aluminum foil rewinding described in the present invention adopts an extrusion roller to provide support force for the aluminum foil roll. The winding roller contacts the surface of the extrusion roller when installed. The diameter of the aluminum foil roll increases continuously during the winding process. The winding roller moves downward continuously under the support of the extrusion roller, so that the winding position of the aluminum foil is always located at the contact position between the aluminum foil roll and the extrusion roller, thereby reducing the tension change during the winding process of the aluminum foil and improving the stability.

[0022] (3) The winding device for aluminum foil rewinding described in the present invention, when installing the winding roller, two clamping columns are placed on the inner side of the two L-plates at the top, and the winding roller is pushed toward the bracket to drive the clamping columns into the inner side of the column groove to achieve installation. When disassembling, the winding roller is grasped from the inner side of the two L-plates at the bottom and moved away from the bracket to facilitate disassembly and assembly of the winding roller.

[0023] (4) The winding device for aluminum foil rewinding described in the present invention adopts the design of the linkage of the impact component and the cutting component by using the compressed spring 2 and the rubber ring, so that when the winding diameter of the winding roller reaches the designed range and the winding stops automatically, a downward impact force is generated, so that the cutter cuts the aluminum foil at a faster speed, thereby improving the cutting effect. At the same time, the power structure cooperates with the impact component, so that the motor can move downward to provide initial power for the impact component, and can move upward to restore the device to its initial state through the return rod, without the need for additional manual operation, thus saving manpower consumption.

A sleeve 29 is sleeved on the outer side of the power rod 28 through a bearing. A large gear 211 is fixedly installed on the outer side of the power rod 28, and a small gear 32 is fixedly installed on the outer side of the winding roller 31, and the small gear 32 is meshed with the large gear 211; the power mechanism 2 also includes a through hole 22, which is opened on one side and the inner wall of both sides of the gantry 1, and the through hole 22 is communicated with the column groove 21, and the gantry Two groups of L plates 23 are fixedly installed on the side of the gantry 1 away from the bracket 11, and each group has two L plates 23. An inlet and outlet hole 24 is opened on the side of the gantry 1 close to the L plate 23. The inlet and outlet hole 24 is flush with the inner side of the L plate 23, and the inlet and outlet hole 24 is communicated with the column slot 21. A partition plate 25 is fixedly installed on the inner side of the column slot 21. The top of the partition plate 25 is flush with the inner side of the inlet and outlet hole 24 near the bottom. A square hole is opened inside the partition plate 25. A large spring 26 is fixedly installed on the inner side of the bottom wall of the column slot 21. The large spring 2 The other end of 6 is fixed to the bottom of the sliding column 27, and a square rod 212 is fixedly installed on the top of the sliding column 27. The square rod 212 passes through the inner side of the square hole, and a top plate 213 is fixedly installed on the other end of the square rod 212. A spring 214 is fixedly installed on the side of the top plate 213 close to the square rod 212, and a bevel block 215 is fixedly installed on the other end of the spring 214. There is a chamfer on the side of the bevel block 215 close to the L plate 23. The top plate 213, the spring 214 and the bevel block 215 are all located on the inner side of the column slot 21.

[0037] The two ends of the squeezing roller 13 are respectively installed on the inner walls of both sides of the gantry 1 through bearings. When in contact with the surface of the aluminum foil roll, the surface friction is used to drive the squeezing roller 13 to rotate. The squeezing roller 13 can smooth the aluminum foil roll and provide support for the aluminum foil roll when the diameter of the aluminum foil roll increases, so that the aluminum foil roll and the winding roller 31 move downward. The column groove 21 can provide a guiding effect for the sliding column 27 and the bevel block 215. The sliding column 27 and the bevel block 215 are both made of light and hard materials to prevent excessive external force from being applied to the large spring 26 and the spring 1 214. A damper is provided on the outside of the sliding column 27, which can slowly restore the large spring 26 to its initial state after losing external force when in a compressed state. The bearing between the power rod 28 and the sleeve 29 can make the two be in different In the active state, the L-plate 23 can provide a guide for the installation and removal of the storage roller, so that the storage roller enters the inner side of the column groove 21 from the inner side of the two L-plates 23 at the top through the clamping column 33, and moves out to the outside from the inner side of the two L-plates 23 at the bottom. The partition plate 25 can divide the column groove 21 into two upper and lower spaces. The column groove 21 space above the plate is used for the movement of the clamping column 33, and the column groove 21 space below the partition plate 25 is used for the movement of the sliding column 27, which is convenient for limiting the movement range of the clamping column 33 and the sliding column 27. The top plate 213 can provide a stable support for the spring 1 214, so that the spring 1 214 gives the clamping column 33 a downward force through the bevel block 215, so that the clamping column 33 can use the force to tightly mesh the small gear 32 with the large gear 211 through the storage roller.

[0038] In this embodiment, a winding assembly 3 is provided inside the gantry 1. The winding assembly 3 is assembled to drive the winding roller 31 to rotate for winding through the meshing transmission of the small gear 32 and the large gear 211. The winding assembly 3 also includes two clamping columns 33. The two clamping columns 33 are respectively mounted on the two ends of the winding roller 31 through bearings. The top and bottom of the clamping columns 33 are chamfered. A clamping groove 34 is opened through the inside of the clamping column 33, and the clamping groove 34 is located on the outside of the square rod 212. The chamfer of the clamping column 33 is convenient for resisting the chamfered surface of the bevel block 215, so that the clamping column 33 can push the bevel block 215 upward into the inner side of the column groove 21.

[0039] In this embodiment, two groups of brackets 11 are fixedly installed on one side of the gantry 1, each group has two brackets 11, and a guide roller 12 is installed on the inner side of each group of brackets 11 through a bearing. A cutting component 6 is fixedly installed on the side of the gantry 1 close to the bracket 11, and the cutting component 6 is used to shear the aluminum foil; a guide component 4 is fixedly installed on one side of the gantry 1, and the guide component 4 is used to limit the movement of the motor 210. An impact component 5 is arranged inside the guide component 4, and the impact component 5 is used to cooperate with the motor 210 to drive the cutting component 6 to automatically shear the aluminum foil. The cutting component 6 includes a cutting plate 61, and the cutting plate 61 is fixedly installed on one side of the gantry 1 close to the bracket 11, and the cutting plate 61 is located at the top of the bracket 11, and an inclined rod 62 is installed on the top of the cutting plate 61 through a hinged structure, and a cutter 63 is fixedly installed on the side of the inclined rod 62 close to the cutting plate 61, and a hole is opened inside the cutting plate 61 to facilitate the cutter 63 to penetrate and cut, and a thin rod 64 is fixedly installed on the other end of the inclined rod 62.

[0040] In this embodiment, the guide assembly 4 includes two fixing plates 41, and the fixing plates 41 are installed on the side of the gantry 1 close to the motor 210. The inside of the two fixing plates 41 is penetrated with a circular hole, and the inner wall of the circular hole close to the bottom is provided with two chamfers. A plurality of guide rods 42 are fixedly installed between the two fixing plates 41, and a plurality of guide rings 43 are fixedly installed on the outer side of the motor 210, and the guide rings 43 are sleeved on the outer side of the guide rods 42. A guide sleeve 44 is fixedly installed on the side of the fixing plate 41 away from the gantry 1. The impact assembly 5 includes a short column 51, and the short column 51 penetrates the inner side of the circular hole close to the bottom fixing plate 41, and the top of the short column 51 is threadedly installed with an adjustment block, and the outer side of the short column 51 is A rubber ring 52 is sleeved, and the rubber ring 52 contacts the chamfer of the circular hole. A support plate 53 is fixedly installed on the outside of the short column 51, and a spring 2 54 is fixedly installed on the top of the support plate 53, and the other end of the spring 2 54 is fixedly installed on the bottom of the fixing plate 41. A special-shaped rod 55 is fixedly installed on the bottom of the short column 51, and the special-shaped rod 55 is located on the inner side of the guide sleeve 44. A return rod 56 is fixedly installed on the inner side of the top wall of the special-shaped rod 55, and the return rod 56 passes through the inner side of the circular hole of the top fixing plate 41. A T-shaped tube 57 is installed on the other end of the special-shaped rod 55 through a bearing. One section of the T-shaped tube 57 connected to the special-shaped rod 55 is a rod, and the other section is a tube. The T-shaped tube 57 is sleeved on the outside of the thin rod 64.

[0041] The guide ring 43 can guide the motor 210 by cooperating with the guide rod 42, so as to prevent the motor 210 from rotating itself while driving the power rod 28 to rotate. The fixing plate 41 can provide a stable support for the guide sleeve 44, so that the guide sleeve 44 can provide a guiding effect for the up and down movement of the special-shaped rod 55. The spring 2 54 is in a compressed state, and the rubber ring 52 cooperates with the circular hole to provide a blocking effect for the extension of the spring 2 54. When the rubber ring 52 passes through the circular hole and reaches the bottom of the fixing plate 41, the impact force generated by the compressed spring 2 54 when the external force is lost is used to drive the cutting assembly 6 to cut, thereby improving the cutting effect and rotating the adjusting block. , the adjusting block can be moved up and down by the action of the thread, which is convenient for adjusting the connection between the power mechanism 2 and the cutting assembly 6, so that when the large gear 211 and the small gear 32 are just separated, the motor 210 pushes the short column 51 through the adjusting block to drive the rubber ring 52 to just move to the bottom of the fixed plate 41, so that the winding roller 31 stops winding and drives the cutting assembly 6 to cut, thereby improving the working efficiency. The return rod 56 is a long rod, which is convenient for disassembling the winding roller 31 and driving the motor 210 to move upward through the large spring 26, so that the motor 210 pushes the return rod 56 to move upward to the initial state, and restores the entire device to the initial state, saving manpower consumption.

[0042] How it works: Initial state reference Figure 4 When in use, grab the winding roller 31 and move it to the position close to the two L plates 23 at the top, place the end of the winding roller 31 with the small gear 32 on the top of the large gear 211, place the two clamping columns 33 on the inner side of the two L plates 23, and make the clamping groove 34 face the gantry 1, push the winding roller 31 along the horizontal position of the L plate 23 toward the gantry 1, so that the winding roller 31 drives the small gear 32 to mesh with the large gear 211, and continue to push the winding roller 31, so that the winding roller 31 drives the two clamping columns 33 to mesh with the bevel block 21 5, so that the clamping column 33 and the bevel block 215 use their own chamfers to push the bevel block 215 to move upward, and the bevel block 215 drives the spring 1 214 to compress and deform, and the clamping column 33 is completely pushed to the inside of the column groove 21. At this time, the upper surface of the winding roller 31 contacts the lower surface of the squeezing roller 13, and the clamping groove 34 is located on the outside of the square rod 212. The spring 1 214 squeezes the clamping column 33 through the bevel block 215 under the support of the top plate 213, and the clamping column 33 drives the small gear 32 to mesh tightly with the large gear 211 through the winding roller 31.

[0043] Then, one end of the aluminum foil is fixed on the surface of the winding roller 31, and the motor 210 is started to drive the power rod 28 to rotate counterclockwise, and the power rod 28 drives the large gear 211 to rotate, so that the large gear 211 drives the small gear 32 to rotate clockwise by meshing with the small gear 32, and the small gear 32 drives the winding roller 31 to rotate clockwise for winding. At this time, the winding roller 31 drives the squeezing roller 13 to rotate counterclockwise by the friction force with the surface of the squeezing roller 13. When the diameter of the aluminum foil roll on the surface of the collecting roller becomes larger and larger, the aluminum foil roll pushes the winding roller 31 downward through the interaction force with the squeezing roller 13, and the winding roller 31 pushes the large gear 211 downward through the small gear 32, so that the large gear 211 drives the power rod 28 to move downward, and the power rod 28 drives the motor 210, the square rod 212 and the components connected to the square rod 212 to move downward together.

[0044] When the radius of the aluminum foil roll increases to be equal to the distance between the winding roller 31 and the sleeve 29, the lower surface of the aluminum foil roll contacts the upper surface of the sleeve 29, and the aluminum foil roll uses the surface friction with the sleeve 29 to drive the sleeve 29 to rotate, so that the sleeve 29 rotates with the power rod 28 as the center under the support of the bearing, and the aluminum foil roll continues to be wound, and pushes the sleeve 29 downward during the winding process, so that the sleeve 29 drives the large gear 211 to move downward through the power rod 28. At this time, the downward movement speed of the large gear 211 is greater than the downward movement speed of the small gear 32, so that the large gear 211 is gradually separated from the small gear 32, and the winding roller 31 drives the clamping column 33 to squeeze the bevel block 215 and the spring 1 214 upward, so that the spring 1 214 gives the winding roller 31 a downward force, thereby increasing the surface friction between the aluminum foil roll and the sleeve 29.

[0045] When the radius of the aluminum foil roll increases to be larger than the sum of the radii of the small gear 32 and the large gear 211, the large gear 211 is completely separated from the small gear 32 and no longer meshes with each other. The motor 210 can only drive the large gear 211 to rotate through the power rod 28, and the small gear 32 does not rotate. At this time, the winding roller 31 loses the rotational force provided by the small gear 32 and does not rotate under the action of the surface friction between the aluminum foil roll and the sleeve 29, thereby automatically stopping the winding. The winding radius is the sum of the radii of the large gear 211 and the small gear 32.

[0046] When the large gear 211 is separated from the small gear 32, the motor 210 moves downward to the top of the fixing plate 41 near the bottom, so that the motor 210 presses the short column 51 downward, and the short column 51 drives the rubber ring 52 to move downward, so that the rubber ring 52 passes downward through the round hole to the bottom of the fixing plate 41. At this time, the spring 2 54 pushes the support plate 53 downward under the action of its own elastic force and the support of the fixing plate 41. The support plate 53 drives the special-shaped rod 55 to move downward, so that the special-shaped rod 55 drives the thin rod 64 to move downward through the T-tube 57, so that the thin rod 64 drives the inclined rod 62 and the cutter 63 to cut the aluminum foil downward, so that when the large gear 211 is separated from the small gear 32, the aluminum foil is automatically cut.

[0047] When the large gear 211 is separated from the small gear 32, the clamping column 33 moves to the top of the partition plate 25, and then the staff grabs the winding roller 31 and moves it away from the bracket 11, so that the winding roller 31 drives the inner side of the two L-plates 23 that move from the column groove 21 to the bottom, and removes the winding roller 31. At this time, the large spring 26 drives the sliding column 27 to move upward under its own elastic force, so that the sliding column 27 moves to the bottom of the partition plate 25. At the same time, the sliding column 27 drives the power rod 28 and the motor 210 to move upward, so that the motor 210 pushes the return rod 56 upward, and by pushing the return rod 56 back to the initial position, the return rod 56 drives the short column 51 and the rubber ring 52 back to the initial position through the special-shaped rod 55, thereby restoring the entire device to its initial state for easy use again.
