Between the two bases, there are respectively arranged an upper knife shaft and a lower knife shaft which are arranged vertically in parallel and synchronously. The two ends of the upper knife shaft and the lower knife shaft are respectively positioned on the corresponding bases through upper knife bearing seats and lower knife bearing seats. Dragging scissors are respectively arranged at the two ends of the upper knife shaft, and the two dragging scissors are located between the two bases. And a thick foil shearing equipment containing the dragging shear mechanism, which includes a circular shear mechanism for trimming the edges of thick foils and several deflector rollers at the front, rear, left and right sides of the circular shear mechanism. The circular shear mechanism includes a vertically adjustable circular shear, and the dragging shear mechanism is arranged between any two deflector rollers.

[0004] Again, the publication number CN204450645U discloses a circular knife suspended shearing mechanism for a slitter, which includes a fixing plate and multiple groups of shearing mechanisms. There is a material passing slot hole in the middle of the fixing plate. At least one linear slide rail and one knife seat fixing shaft are respectively arranged on both sides of the material passing slot hole. Each group of the multiple groups of shearing mechanisms is composed of two shearing mechanisms, and the two shearing mechanisms are respectively located on the linear slide rails on both sides of the material passing slot hole. Each shearing mechanism includes a knife seat, a servo motor and a circular knife. The bottom of the knife seat has a bearing that cooperates with the linear slide rail on the fixing plate for sliding. The servo motor is horizontally fixed on the knife seat through a column, and the circular knife is connected to the servo motor.

[0005] However, the above technologies all adopt single-sided shearing circular knives. The lower knife shaft uses a knife shaft assembled with a knife ring, a back knife and a bottom knife. Both the upper and lower knife shafts need to be connected to a transmission motor through a one-to-one gear to realize the production mode of active shearing of the upper and lower knife shafts. When producing thin materials, quality defects such as wavy edges, curled edges and knife back imprints are likely to appear at the edges of the foils.

[0006] Therefore, a foil scissors is proposed to solve the above technical problems. Content of the Utility Model

[0008] The technical solution adopted by the present utility model to solve the problem is as follows: A foil scissors, comprising: a lower knife shaft and an upper knife shaft. A plurality of knife rings are arranged on the lower knife shaft. Bottom knives are arranged at one end of two adjacent knife rings close to each other. A plurality of cutting tools are arranged on the upper knife shaft. The cutting tools are located between two corresponding bottom knives. The cutting tools are double-sided edge-opening circular knives.

[0009] As a further improvement of the above technical solution, it further comprises a variable-frequency motor. A transmission mechanism is arranged on the variable-frequency motor. The variable-frequency motor drives the upper knife shaft to rotate through the transmission mechanism.

[0010] As a further improvement of the above technical solution, the transmission mechanism includes a reducer. The reducer is fixedly installed on the variable-frequency motor. A first belt pulley is fixedly installed on the output shaft of the reducer. A second belt pulley is fixedly installed on the upper knife shaft. The same belt is rotatably sleeved on the second belt pulley and the first belt pulley.

[0011] As a further improvement of the above technical solution, the distance between two adjacent bottom knives is 0.5 - 2 mm.

[0012] As a further improvement of the above technical solution, the edge thickness of the cutting tool is 0.1 - 0.5 mm.

[0013] The beneficial effects of the present utility model are as follows: Through the cooperation of the cutting tool and the bottom knife, thin material cutting can be realized, and the product quality can be improved. At the same time, the transformation cost of the cutting tool is low. The cutting tool retains the cutting method of the upper and lower knife shafts. The valuable cutting tools such as the knife shaft, bottom knife, and knife ring are utilized on the premise that they can be used, reducing the transformation cost. Description of the Drawings
