[0002] The integrated foil production machine is widely used in the production process of copper foil. Its main working principle is to connect the anode tank to the positive electrode and the cathode roller to the negative electrode. At the same time, direct current is introduced and the copper ions in the copper sulfate are precipitated and precipitated on the cathode roller by electrolysis technology to generate copper foil. By adjusting the current density and the speed of the cathode roller, copper foil products of different thicknesses can be produced. For the copper foil produced in this way, due to the defects of the edge quality of the copper foil and the adjustment of the product width according to different needs, the edges of the copper foil products need to be trimmed.

[0003] Since the cut edge material can be reused by melting copper, a special mechanism is needed to collect the edge material. As the edge material is rolled up, the diameter of the roll will gradually increase and the weight will continue to increase. In traditional technology, the foil machine manually removes the edge material, which has the problems of heavy labor load, inconvenient operation, and potential safety hazards in the unloading process. Therefore, it is urgent to provide a device that can automatically remove the edge material. Summary of the invention

DETAILED DESCRIPTION

[0020] The utility model will be further described below in conjunction with the accompanying drawings.

[0021] like Figure 1 and Figure 2 As shown, the utility model provides an automatic edge material unloading device, comprising a coiling mechanism, a unloading mechanism and a base 1;

[0022] The winding mechanism is fixed on the base 1 with the aid of a fixing bracket 13 and is used to wind up the edge material 15 ; the winding mechanism includes a winding shaft 3 , and in order to stably drive the winding shaft 3 to rotate, the winding shaft 3 is rotatably mounted on the top of the base 1 through a bearing seat 4 .

[0023] As a preferred embodiment, the coiling shaft 3 is an air-expanding shaft, wherein the end of the air-expanding shaft can be connected to a rotary joint. The air-expanding shaft comprises a transmission section and an expansion section, wherein the expansion section extends to the left side of the left end of the base 1, and the transmission section is rotatably mounted on the top of the base 1 through a bearing seat 4. Since the movable parts (key strips or slats) on the surface of the air-expanding shaft will bulge after inflation, and the movable parts on the surface will quickly retract after deflation, the air-expanding shaft in the expanded state can be used to realize the winding operation of the copper foil edge material, and at the same time, the copper foil edge material can be quickly detached from the air-expanding shaft in the retracted state to quickly realize the unwinding operation.

[0024] Preferably, the winding mechanism includes a winding shaft 3 and a driving mechanism 5, wherein the driving mechanism 5 is connected to the winding shaft 3 and is used to drive the winding shaft 3 to rotate. In order to achieve a precise driving process, the driving mechanism 5 is connected to the winding shaft 3 through a synchronous belt 6. As a further preferred embodiment, the driving mechanism 5 is a driving motor, wherein a driven wheel is mounted on the winding shaft 3, and a driving wheel 7 is mounted on the output shaft of the driving mechanism 5, and the synchronous belt is wound around and connected to the driven wheel and the driving wheel.

[0025] In order to achieve high-precision positioning at any angle during the rotation of the coil shaft 3, the driving mechanism 5 is a servo motor.

[0026] The unloading mechanism is arranged at the rear end of the coiling mechanism and is fixed on the base 1 with the aid of a fixing bracket 13. The unloading mechanism is used to remove the edge material 15 on the coiling mechanism through a lateral telescopic action. As a preferred embodiment, the unloading mechanism can be arranged above the coiling shaft 3.

[0027] Preferably, the unloading mechanism includes a unloading component 2 and a driving mechanism 11. The unloading component 2 is spaced apart from the winding shaft 3. The driving mechanism 11 can be supported on the base 1 through a mounting seat 13. In order to effectively eliminate the interference caused by the connection error, one end of the driving mechanism 11 is connected to the unloading component 2 through a floating joint 10, which is used to drive the unloading component 2 to reciprocate along the axial direction of the winding shaft 3.

[0028] As a preference, the driving mechanism 2 11 is a cylinder, and as a further preference, the cylinder is a spring-reset cylinder, and a regulating valve 12 is connected to the air port of its rodless cavity, and the air inlet of the regulating valve 12 is connected to the high-pressure air source through a high-pressure air circuit, thereby facilitating the use of the high-pressure air source to drive the extension and retraction action of the cylinder.

[0029] In order to quickly remove the edge material on the coil shaft 3 by lateral pushing, the unloading assembly 2 is a pushing plate with a through hole in the center, and the unloading assembly 2 is sleeved on the coil shaft 3 through the through hole in the center. Of course, the unloading assembly 2 can also be an arc-shaped semicircular disk.

[0030] In order to enable the unloading assembly to stably perform transverse reciprocating motion, a transverse guide mechanism 14 is also included, which is connected to the unloading assembly 2 and is used to assist the unloading assembly 2 in reciprocating motion. In order to more stably assist the pusher assembly 2 to reciprocate along the axial direction of the coil shaft 3, the number of the transverse guide mechanisms 14 is at least two, and they are relatively distributed on both sides of the coil shaft 3.

[0031] As a preferred embodiment, the lateral guide mechanism 14 includes a guide sleeve 8 and a guide rod 9; the guide sleeve 8 is fixed to the outside of the winding shaft 3, and the guide rod 9 is axially slidably inserted into the guide sleeve 8, and the other end of the guide rod 9 is connected to the unloading assembly 2.

[0032] In the utility model, by using a bearing seat to rotatably mount the coil shaft on the top of the base, it is convenient to drive the coil shaft to rotate, and then it is convenient to complete the winding operation of the copper foil edge material. Since the surface movable parts (key strips or strips) of the air-expanding shaft will bulge after inflation, and the surface movable parts will quickly retract after deflation, the air-expanding shaft in the expanded state can be used to realize the winding operation of the copper foil edge material. At the same time, the copper foil edge material can be quickly separated from the air-expanding shaft in the retracted state to quickly realize the unwinding operation. By connecting a rotary joint at the end of the air-expanding shaft, a stable supply of air source can be carried out in the rotating state of the air-expanding shaft. The servo motor is installed on one side of the air-expanding shaft, and a driving wheel is installed on the outside of its output shaft. At the same time, a driven wheel is installed on the air-expanding shaft, and the driving wheel and the driven wheel are connected by a synchronous belt. The advantages of the accurate synchronous belt transmission can be fully utilized, ensuring that no slip occurs during transmission, which is conducive to the precise driving of the air-expanding shaft rotation through a constant transmission ratio. In addition, due to the good flexibility of the synchronous belt, its movement process belongs to flexible transmission, so it can have a good protective effect on the servo motor. Connecting the driving mechanism 2 to the unloading assembly through a floating joint can effectively eliminate the interference caused by the connection error, and can allow the connection offset. At the same time, it can facilitate the adjustment of the connection angle during the rotation process, improve the dynamic performance of the shaft system, and at the same time, it is beneficial to protect the driving mechanism 2. By setting a lateral guide mechanism on the outside of the air expansion shaft, the unloading plate can always be in a stable position, ensuring the reliability and stability of the rotation of the air expansion shaft, and at the same time, it also ensures the reliability and stability of the lateral movement of the unloading plate. The device is easy to operate and can significantly improve the unloading efficiency. At the same time, it can reduce the labor load of the operator and improve the safety factor during the unloading process.
