Abstract
Description
Technical Field
[0001] This application relates to the technical field of rewinding and feeding, and in particular to a rewinding device for hot stamping foil rewinding. Background Technology
[0002] Currently, in the hot foil stamping production and processing industry, hot foil stamping rewinding is a key process.
[0003] In the hot stamping machine production process, the horizontal foil take-up setting does not pass through the foil take-up roller at the factory. Instead, it is directly wound on the foil take-up shaft. This makes it impossible to produce electroplated aluminum with large step skips and multiple horizontal step skips at the same time, as well as high static electricity. The waste foil needs to be replaced frequently during the production process.
[0004] Regarding the aforementioned technologies, the applicant believes that there are defects that affect production efficiency. Utility Model Content
[0005] To solve the above-mentioned technical problems, this application provides a rewinding device for hot stamping foil rewinding.
[0006] This application provides a rewinding device for hot stamping foil rewinding, which adopts the following technical solution:
[0007] A rewinding device for hot stamping foil rewinding includes a frame, a foil take-up roller, a roller support assembly, a roller drive assembly, and a waste foil collection box. The foil take-up roller includes multiple hubs and multiple flexible fiber layers. The hubs are mounted on the roller support assembly, and all hubs have the same axial center position. The hubs are rotatably connected to the roller support assembly. The flexible fiber layers are mounted on the outer surface of the hubs and are fitted into the hubs. The roller support assembly is mounted on the frame and is fixedly connected to the frame. The roller drive assembly is mounted on the frame and is fixedly connected to the frame. The waste foil collection box is installed below the foil take-up roller and is detachably connected to the frame.
[0008] By adopting the above technical solution, the hub provides rotational support for the flexible fiber layer, which covers the outer surface of the hub. Its flexible material can be closely attached to the surface of the hot stamping foil, and the hot stamping foil is rolled up by friction. The foil wheel drive assembly provides rotational power for the foil take-up wheel, and the foil wheel support assembly is connected to the hub shaft through bearings to ensure that the foil take-up wheel rotates while maintaining coaxiality. The waste foil collection box is used to collect the waste foil peeled off from the hot stamping foil during the winding process, so as to avoid the accumulation of waste foil affecting the operation of the device or polluting the working environment.
[0009] Preferably, the wheel support assembly includes multiple bearing frames and multiple bearings. The bearing frames are all fixedly mounted on the frame, the bearings are mounted on the bearing frames, the outer rings of the bearings are rotatably connected to the bearing frames, and the inner rings of the bearings are fixedly connected to the outer rings of the wheel hub.
[0010] Preferably, a rubber washer is installed at the mating position of each bearing and bearing housing, and the rubber washer is sleeved on the bearing.
[0011] By adopting the above technical solution, the bearing bracket, as the mounting carrier of the bearing, ensures the coaxiality of the take-up foil roller through a fixed connection with the frame, and bears the radial and axial loads when the take-up foil roller rotates, preventing the roller from shifting or shaking. The bearing, through a fixed connection with the hub, transmits the power of the roller drive assembly to the hub. The rubber gasket absorbs the impact force generated when the bearing rotates, reducing the rigid collision between the bearing and the bearing bracket, and preventing the take-up foil roller from becoming eccentric or the winding accuracy from decreasing due to vibration.
[0012] Preferably, the bob wheel drive assembly includes a motor and an output shaft. The motor is mounted on a frame and is fixedly connected to the frame. An output shaft is mounted on the output end of the motor and is fixedly connected to the output end of the motor. The output shaft passes through all bob wheel support assemblies and is fixedly connected to the inner ring of each hub.
[0013] By adopting the above technical solution, the motor serves as the power source to provide rotational driving force, and the output shaft acts as the transmission bridge between the motor and the take-up foil wheel, synchronously transmitting the rotational motion of the motor to all the hubs, ensuring that multiple hubs rotate at the same speed, and achieving uniform winding of large and small hot foil.
[0014] Preferably, a first slide rail is provided on the frame on the lower side of the waste foil collection box. The first slide rail is fixedly connected to the frame, and the waste foil collection box is slidably connected to the first slide rail. Cards are provided at both ends of the first slide rail, and the cards are rotatably connected to the first slide rail. The inner end faces of the cards at both ends are in contact with the waste foil collection box.
[0015] By adopting the above technical solution, the first slide rail provides a sliding path for the waste foil collection box, ensuring its stable movement trajectory on the frame and facilitating installation and disassembly. By rotating the card, its inner end face contacts the collection box, limiting the axial displacement of the collection box on the slide rail and preventing the collection box from sliding or falling out due to vibration or external force during operation. Rotating the card can fix or release the collection box, making it easy for operators to quickly clean up waste foil.
[0016] Preferably, the frame is further provided with a guide tensioning mechanism, which includes a bogie and a tensioning frame. The bogie is installed below the hot stamping position and is fixedly connected to the frame. The tensioning frame is installed obliquely above the foil take-up roller and is fixedly connected to the frame.
[0017] By adopting the above technical solution, after the hot stamping process is completed, the paper and waste foil are transported separately. The waste foil usually needs to change the transport direction to enter the foil collection wheel. The bogie provides the waste foil with a corresponding turning trajectory through its structure. The tensioning frame assists the bogie in completing the tensioning of the waste foil, ensuring that the waste foil can be smoothly transported to the foil collection wheel.
[0018] Preferably, the frame is provided with a cleaning mechanism, which includes a cleaning brush and a second slide rail. The second slide rail is fixedly installed on the frame, the cleaning brush is located on one side of the foil collection wheel, and the cleaning brush is slidably connected to the second slide rail.
[0019] By adopting the above technical solution, after the foil collecting wheel has been used for a long time, the flexible fiber layer adsorbs waste foil fragments or fiber lint. The cleaning brush can brush off the impurities by sliding relative to the flexible fiber layer, preventing the accumulation of waste foil or other debris on the flexible fiber layer from affecting its continued operation.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] 1. The hub provides rotational support for the flexible fiber layer, which covers the outer surface of the hub. Its flexible material can closely adhere to the surface of the hot stamping foil, and the hot stamping foil is rolled up by friction. The foil wheel drive assembly provides rotational power for the foil take-up wheel. The foil wheel support assembly is connected to the hub shaft through bearings to ensure that the foil take-up wheel rotates while maintaining coaxiality. The waste foil collection box is used to collect the waste foil peeled off from the hot stamping foil during the winding process, so as to avoid the accumulation of waste foil affecting the operation of the device or polluting the working environment.
[0022] 2. The bearing bracket serves as the mounting carrier for the bearing. Through its fixed connection with the frame, it ensures the coaxiality of the take-up foil rollers and bears the radial and axial loads when the take-up foil rollers rotate, preventing the rollers from shifting or shaking. The bearing, through its fixed connection with the hub, transmits the power of the roller drive assembly to the hub. The rubber gasket absorbs the impact force generated when the bearing rotates, reducing rigid collisions between the bearing and the bearing bracket, and preventing the take-up foil rollers from becoming eccentric or the winding accuracy from decreasing due to vibration.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0029] This application discloses a rewinding device for rewinding hot stamping foil. (Refer to...) Figure 1-4 The system includes a frame 1, a foil collecting wheel 2, a foil collecting wheel support assembly 3, a foil collecting wheel drive assembly 4, and a waste foil collection box 5. Multiple bearing brackets 31 are fixedly installed on the frame 1 according to the designed positions, ensuring accurate installation of the bearing brackets 31 to guarantee the coaxiality of the foil collecting wheel 2. Multiple bearings 32 are respectively installed on their corresponding bearing brackets 31, with the bearing brackets 31 installed at an angle. Multiple hubs 21 are installed one-to-one on the bearings 32 of the foil collecting wheel support assembly 3, with the hubs 21 extending to and fixed to the inner ring of the bearing 32. Rubber washers 33 are fitted at the mating points of each bearing 32 and bearing bracket 31 to ensure the coaxiality of all hubs 21. The axis positions are strictly aligned to ensure the overall coaxiality of the take-up foil rollers 2. The flexible fiber layer 22 is tightly embedded and installed on the outer surface of the hub 21. The flexible material of the flexible fiber layer 22 allows it to fit tightly against the waste foil surface, providing friction for the subsequent winding action. The motor 41 is securely installed on the frame 1. An output shaft 42 is installed at the output end of the motor 41, ensuring that the output end of the motor 41 and the output shaft 42 are fixedly connected. The output shaft 42 passes through all the foil roller support components 3. The output shaft 42 is fixedly connected to the inner ring of each hub 21. The rotational power of the motor 41 is transmitted to each take-up foil roller 2 through the output shaft 42.
[0030] A second slide rail 12 is fixedly installed on the frame 1, and its installation position is determined to facilitate the cleaning brush 71's cleaning operation on the foil collecting wheel 2. The cleaning brush 71 is installed on the second slide rail 12, allowing it to slide flexibly on the second slide rail 12, making it easy to remove the cleaning brush 71 for replacement or cleaning. The waste foil collection box 5 is fixed below the foil collecting wheel 2. A first slide rail 11 is installed on the frame 1, ensuring that the first slide rail 11 is firmly connected to the frame 1. The waste foil collection box 5 is slidably connected to the first slide rail 11, allowing the waste foil collection box 5 to slide flexibly on the first slide rail 11. Smoothly slide on the slide rail 11. Cards 111 are installed at both ends of the first slide rail 11, so that the cards 111 are rotatably connected to the two ends of the first slide rail 11. By rotating the cards 111, their inner end faces are made to fit against the waste foil collection box 5, which restricts the axial displacement of the collection box on the first slide rail 11 and prevents the collection box from shaking during operation. Below the hot stamping position, the bogie 61 provides a turning trajectory for the waste foil according to the design requirements. Above the foil collecting wheel 2, the tensioning frame 62 is installed at an angle, and it is ensured that the tensioning frame 62 is firmly fixedly connected to the frame 1 to assist the bogie 61 in completing the tensioning work of the waste foil.
[0031] The flexible fiber layer 22 in the foil collecting wheel 2 is closely attached to the surface of the waste foil, so the waste foil is rolled up by friction. During the rolling process, the stripped waste foil falls into the waste foil collection box 5 below. After long-term use, if the flexible fiber layer 22 adsorbs waste foil fragments or fiber lint, the operator can push the cleaning brush 71 to slide it on the second slide rail 12, so that it slides relative to the flexible fiber layer 22, thereby brushing off the impurities.
[0032] The working principle of the rewinding device for hot stamping foil rewinding in this application is as follows: After the hot stamping process is completed, the paper and waste foil are conveyed separately. The waste foil changes its conveying direction under the guidance of the bogie 61, and is simultaneously conveyed to the take-up foil roller 2 with appropriate tension under the auxiliary tensioning action of the tensioning frame 62. The motor 41 is started, and the motor 41 transmits the rotational power to the hub 21 of the take-up foil roller 2 through the output shaft 42, causing the hub 21 to drive the flexible fiber layer 22 to rotate. Since the flexible fiber layer 22 is closely attached to the surface of the waste foil, the rewinding action of the waste foil is achieved by using friction. During the winding process, the stripped waste foil falls into the waste foil collection box 5 below. After the foil winding roller 2 has been used for a long time, if the flexible fiber layer 22 absorbs waste foil fragments or fiber lint, the operator can push the cleaning brush 71 to slide it on the second slide rail 12, creating relative sliding with the flexible fiber layer 22, thereby brushing off the impurities. When the waste foil collection box 5 is full of waste foil, the card 111 is rotated to separate it from the waste foil collection box 5. Then the waste foil collection box 5 is pulled out along the first slide rail 11 for cleaning. After cleaning, it is pushed back to its original position and the card 111 is rotated to fix it.
[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
