The driving assembly 300 has a driving force output end 301 connected to the first connecting point 201 for driving the cutting arm 110 to reciprocate along the first sliding slot 210.
When the glass frit shearing device is used, the two shearing arms 110 are hinged in a crossed mode, under the action of the tensile force of the tension spring 130 positioned on the driving section 112, the two shearing sections 111 move oppositely, and the shearing head 120 is driven to shear the glass frit. Since the fixed block 230 opens the included angle between the two driving sections 112, the extension spring 130 is always in an extended state, and the two driving sections 112 are pulled, the fixed block 230 located inside the two driving sections 112 is always in contact with the driving sections 112. When the first connecting point 201 is driven by the driving assembly 300, the shearing arm 110 moves away from the fixed block 230 along the first chute 210, the included angle between the two driving sections 112 decreases, correspondingly, the two shearing sections 111 move oppositely, and the shearing head 120 shears the glass frit; when the first connecting point 201 is driven by the driving assembly 300, the shearing arm 110 moves close to the fixing block 230 along the first sliding chute 210, the included angle between the two driving sections 112 increases, correspondingly, the two shearing sections 111 move back to back, the gap between the two shearing heads 120 increases, and the molten glass flows down.
When the shearing action is implemented, the two shearing arms 110 take the first connecting point 201 as a fulcrum, the extension spring 130 provides shearing power with equal magnitude, the section from the connecting point of the extension spring 130 and the driving section 112 to the fulcrum is taken as a power arm, the shearing section 111 is taken as a resistance arm, and the shearing force obtained by the lever theorem when the two shearing heads 120 shear the molten glass is the same, so that the quality of the molten glass sheared by the device is controllable, and the device is favorable for subsequent production.
When the shearing head 120 moves to the shearing point, that is, the shearing action is in place to shear the molten glass, the two shearing heads 120 are in contact, and the molten glass is sheared by the two shearing forces of the two shearing heads 120 in the same position and opposite directions.

And because the distance from the shearing head 120 to the first connecting point 201 is the arm length of the resistance arm, the distance from the two shearing heads 120 to the first connecting point 201 is the radius length of the circular arc track when the shearing head 120 performs shearing action, and the circular arc track radii of the two shearing heads 120 are equal, that is, the length of the resistance arm of the two shearing sections 111 is equal.
The resistance of the two shearing sections 111 can be obtained to be equal through a lever principle, namely the product of the power and the power arm is equal to the product of the resistance and the resistance arm, the resistance in the lever principle and the shearing force of the shearing arm 110 to the glass liquid are acting force and reacting force, namely the shearing force of the shearing head 120 to the glass liquid is equal to the resistance of the shearing section 111, and then the shearing force of the two shearing arms 110 to the glass liquid is equal.

As shown in fig. 1, when the planar groove cam 310 rotates about its rotational axis, the distance between the second slider 320 and the rotational axis varies, i.e., there are a maximum value and a minimum value of the distance between the second slider 320 and the rotational axis, and the distance between the second slider 320 and the rotational axis uniformly increases and decreases between the maximum value and the minimum value as the planar groove cam 310 rotates. Correspondingly, while the distance between the second slider 320 and the planar groove cam 310 changes, the second slider 320 slides in the second sliding slot 332 to drive the swing link 330 to swing.

Since the forward arc segment 3112 and the backward arc segment 3111 correspond to the moving direction of the shearing arm 110 along the first sliding slot 210, and the annular curve is a smooth curve, the shearing arm 110 moves smoothly along the first sliding slot 210, thereby ensuring smooth completion of the shearing action.
Preferably, the arc length of forward arc segment 3112 is less than the arc length of backward arc segment 3111.
The cutting head 120 of the cutting arm 110 is cooled by heat dissipation to the surrounding environment.
