Die opening and closing mechanism for high-speed panel-type blister packing machine

Abstract

The invention provides a die opening and closing mechanism for a high-speed panel-type blister packing machine. The die opening and closing mechanism comprises a cam driven by a spline spindle, a cooling water plate which moves vertically along a linear guiding system, a lower die arranged on the cooling water plate, and an upper die located above the lower die, and is characterized by further comprising a pulling rod guide plate which is driven by the cam to move horizontally leftwards and rightwards; the pulling rod guide plate is connected with a lifting axle base; one end of the lifting axle base is fixedly hinged, and the lifting axle base is driven by the pulling rod guide plate to swing around a hinge point at the end; the other end of the lifting axle base is hinged to a connection rod mechanism; and while the lifting axle base swings, the lower die is driven by the connection rod mechanism to move vertically along the linear guiding system. According to the die opening and closing mechanism for the high-speed panel-type blister packing machine, die closing pressure is dissolved through a connection rod mechanism method, and load is prevented from acting on cam transmission directly. When the die closing pressure is a definite value, the torque for driving the cam to rotate is reduced exponentially, so that the output torque of an electric motor is reduced; the output rotation speed of the electric motor is increased; and the operation speed of the blister packing machine is enhanced.

Description

technical field [0001] The invention relates to a mold opening and closing mechanism of a high-speed flat blister machine. Background technique [0002] The opening and closing mechanism of the existing high-speed flat blister machine is as follows: figure 1 As shown, it includes cam box 1, spline spindle 2, cam 3, roller 4, roller seat 5, lower mold guide plate 6, cooling water plate 7, lower mold 8, clamping platen 9, upper mold 10, upper mold bottom plate 11 , Upper mold cover plate 12, ball nut 13, adjustment nut 14, guide column 15, steel column cover 16, cam box support shaft 17, column and tighten nut 18. Through the above mechanism, the opening and closing function of the upper and lower molds of the flat blister machine can be realized. The above-mentioned mold opening and closing mechanism is powered by the motor input to the spline main shaft 2, the spline main shaft 2 drives the cam 3 to rotate, and the cam 3 rotates to promote the movement of the roller 4, the...

Problems solved by technology

The result is: when ensuring the safe use of the motor and the rated torque output, the output speed of the motor cannot meet the speed requirements of the blister machine; in the case of ensuring the high-speed operation of the blister machine, due to insufficient output torque, it cannot Complete the closing of the upper and lower molds

Therefore, the existing technology cannot meet the requirement that the operating speed of the blister machine reaches 80 times / min, or even 100 times / min, and has become a technical bottleneck that must be broken through in the development of the high-speed flat-type blister machine.
