[0002] A medium-high voltage corrosion foil production line is a production line for the production and processing of medium-high voltage corrosion foils, which consists of a variety of equipment and devices, including a roll-changing and winding device. The automatic winding and winding during the processing of corrosion foils are mainly realized through a winding roller. After winding to a set thickness, the automatic replacement of the winding is realized through a roll-changing mechanism.

[0003] During the process of roll changing and winding of the existing medium-high voltage corrosion foil production line, the entire machine needs to be stopped for operation so that the staff can replace the winding roller. The process of repeatedly stopping and starting the machine for a long time is rather cumbersome, and it will also affect the overall winding speed of the winding mechanism. Therefore, a roll-changing and winding buffer device for a medium-high voltage corrosion foil production line is proposed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a roll-changing and winding buffer device for a medium-high voltage corrosion foil production line, including a support base. Two first transmission shafts and a second transmission shaft distributed left and right are installed on the front end face of the support base. Two fixed plates distributed up and down are fixedly connected to the front end face of the support base. A lead screw is movably connected between the two fixed plates through bearings. A cross bar is threadedly connected to the outer wall of the lead screw. Two driving rods distributed left and right are fixedly connected to the upper end face of the cross bar. Two support plates are fixedly connected to the upper end faces of the two driving rods. Two springs distributed front and back are fixedly connected to the lower end faces of the two support plates. The lower end faces of the two springs are fixedly connected to a U-shaped frame. A buffer shaft is fixedly connected inside the U-shaped frame. A winding shaft is fixedly connected to the front end face of the support base and is located right below the second transmission shaft.

[0006] In order to facilitate the rotation of the lead screw, preferably, a motor is installed on the upper end face of the upper fixed plate of the roll-changing and winding buffer device of the utility model. The output end of the motor penetrates through the fixed plate and is fixedly connected to the lead screw.

[0007] To prevent the two driving rods from rotating axially, preferably in the roll-changing and winding buffer device of the medium-high voltage etched foil production line of the present utility model, two left-right distributed chutes are fixedly connected to the upper end surface of the support base, and sliders are fixedly connected to the rear end surfaces of the two driving rods, and the two sliders are respectively slidably connected to the two chutes.

[0008] For the stability of spring contraction, preferably in the roll-changing and winding buffer device of the medium-high voltage etched foil production line of the present utility model, limiting grooves are respectively formed through the upper end surfaces of the two support plates, limiting plates are fixedly connected to the upper end surfaces of the two U-shaped frames, and the two limiting plates are respectively slidably connected to the two limiting grooves.

[0009] To facilitate the support of the etched foil, preferably in the roll-changing and winding buffer device of the medium-high voltage etched foil production line of the present utility model, an auxiliary shaft located between the first transmission shaft and the second transmission shaft is fixedly connected to the front end surface of the support base.

[0010] To enable the buffer shaft to have better wear resistance, preferably in the roll-changing and winding buffer device of the medium-high voltage etched foil production line of the present utility model, the two buffer shafts are both made of cemented carbide.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] When the present utility model is in use, first, the etched foil is tightened through the first transmission shaft and the second transmission shaft and the etched foil is conveyed to the winding roller for winding. When roll change is needed, first, the motor drives the lead screw to rotate, so as to drive the cross bar, the driving rod, the support plate and the buffer shaft to move downward, so that the buffer shaft presses the etched foil to bend the etched foil, thereby lengthening the conveying stroke of the etched foil, so as to have time to replace the winding roller, so as to achieve the purpose of being able to lengthen the conveying stroke of the etched foil during the roll change process, without repeated shutdowns many times, and being convenient to use.

Detailed implementation mode

[0017] Please refer to Figures 1 to 3 For the roll-changing and winding buffer device of the medium-high voltage etched foil production line, it includes a support base 1. Two first drive shafts 7 and a second drive shaft 6 distributed left and right are installed on the front end face of the support base 1. Two fixed plates 3 distributed up and down are fixedly connected to the front end face of the support base 1. A lead screw 2 is movably connected between the two fixed plates 3 through bearings. A cross bar 8 is threadedly connected to the outer wall of the lead screw 2. Two drive rods 9 distributed left and right are fixedly connected to the upper end face of the cross bar 8. Two support plates 11 are fixedly connected to the upper end faces of the two drive rods 9. Two springs 12 distributed front and back are fixedly connected to the lower end faces of the two support plates 11. A U-shaped frame 15 is fixedly connected to the lower end faces of the two springs 12. A buffer shaft 16 is fixedly connected inside the U-shaped frame 15. A winding shaft 18 located right below the second drive shaft 6 is fixedly connected to the front end face of the support base 1.

[0018] In this embodiment: During roll change, the lead screw 2 is driven to rotate by the motor 5, so that the cross bar 8 can be driven to move up and down. When the cross bar 8 moves downward, the two drive rods 9 can be driven to move downward. When the two drive rods 9 move downward, the two support plates 11, springs 12, U-shaped frame 15 and buffer shaft 16 are driven to move downward, so that the two buffer shafts 16 squeeze the etched foil and bend the etched foil to lengthen the conveying stroke of the etched foil. The spring 12 can prevent the etched foil from breaking due to excessive force during the process of lengthening the etched foil.

[0019] As a technical optimization scheme of the present utility model, a motor 5 is installed on the upper end face of the upper fixed plate 3. The output end of the motor 5 penetrates through the fixed plate 3 and is fixedly connected to the lead screw 2.

[0020] In this embodiment: The lead screw 2 can be driven to rotate by the motor 5.

[0021] As a technical optimization scheme of the present utility model, two chutes 13 distributed left and right are fixedly connected to the upper end face of the support base 1. Two sliders 10 are fixedly connected to the rear end faces of the two drive rods 9. The two sliders 10 are respectively slidably connected to the two chutes 13.

[0022] In this embodiment: By respectively sliding the two sliders 10 on the two chutes 13, the two drive rods 9 can be prevented from axially rotating.

[0023] As a technical optimization scheme of the present utility model, limiting grooves 4 are respectively formed through the upper end faces of the two support plates 11. Limiting plates 14 are fixedly connected to the upper end faces of the two U-shaped frames 15. The two limiting plates 14 are respectively slidably connected to the two limiting grooves 4.

[0024] In this embodiment, the stability of the movement of the two U-shaped frames 15 can be increased by slidingly connecting the two limit plates 14 to the two limit grooves 4 respectively.

[0025] As a technical optimization scheme of the present utility model, the front end face of the support base 1 is fixedly connected with an auxiliary shaft 17 located between the first transmission shaft 7 and the second transmission shaft 6.

[0026] In this embodiment, the corrosion foil can be conveniently supported by the auxiliary shaft 17, so that the two buffer shafts 16 can conveniently extrude the corrosion foil to move downward.

[0027] As a technical optimization scheme of the present utility model, the two buffer shafts 16 are both made of cemented carbide.

[0028] In this embodiment, by setting the two buffer shafts 16 to be made of cemented carbide, the buffer shafts 16 can have good wear resistance.

[0029] Working principle: During roll change, the motor 5 drives the lead screw 2 to rotate, so that the cross bar 8 can be driven to move up and down. When the cross bar 8 moves downward, it can drive the two drive rods 9 to move downward. When the two drive rods 9 move downward, they drive the two support plates 11, springs 12, U-shaped frames 15 and buffer shafts 16 to move downward, so that the two buffer shafts 16 extrude the corrosion foil and bend the corrosion foil to lengthen the conveying stroke of the corrosion foil, so as to have time for roll change operation. The spring 12 can prevent the corrosion foil from breaking due to excessive force during the process of lengthening the corrosion foil.

[0030] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
