Sealing machine and sealing method thereof

Abstract

The invention provides a sealing machine which comprises a rack, a control device and an air cylinder, wherein the control device and the air cylinder are arranged on the rack; the rack is provided with a conveyer, a filling device, a discharge device, an upper die, an upper die core, inserting angles, clamp plates, a lifting device, a vacuumizing device and a fixed mount; the filling device is communicated with the conveyer; the inserting angles include an upper inserting angle and a lower inserting angle; the lifting device is arranged at the lower end of the rack; the two ends of each inserting angle are respectively provided with a clamp plate; the air cylinder is provided with a correcting device, and the air cylinder is electrically connected with the control device; and the control device is electrically connected with the conveyer, the filling device, the discharge device, the inserting angles, the clamp plates, the vacuumizing device and the lifting device. According to the sealing machine provided by the invention, through the setting of the upper inserting angle, the precision and speed of forming are improved; through the setting of the lower inserting angle, the problem that a bag is required to be often lengthened is solved; and through the setting of the clamp plates, the width can be fixed, and the overall rigidity can be increased, thereby greatly improving the rate of finished products.

Description

technical field [0001] The invention relates to the field of packaging bag sealing machine manufacturing, in particular to a sealing machine, in particular to a sealing machine and a sealing method for sanitary napkin packaging bags. Background technique [0002] The existing sealing machine must be manually put into the sealing machine for semi-automatic sealing, and the length of the sealed flexible packaging bag must be increased by 15mm-25mm, so the cost of the user is virtually increased when the manual semi-automatic sealing is performed, and the yield rate is only within 2mm of the wrong side. About 90%; Compared with manual sealing, the personnel cannot be reduced, so it cannot be widely promoted and applied at all. Contents of the invention [0003] The invention proposes a sealing machine, which solves the problem that in the prior art, when the length of the plastic bag is too short, the sealing machine needs to increase the length of the plastic bag, and the se...

Problems solved by technology

[0003] The invention proposes a sealing machine, which solves the problem that in the prior art, when the length of the plastic bag is too short, the sealing machine needs to increase the length of the plastic bag, and the sealing machine is easy to make wrong sides. The structure is simple, and the input cost of the customer is low. High, no need to increase the length of the plastic bag, improve the yield, reduce the error rate, reduce labor expenditure and labor costs, improve the appearance and grade of the product, and improve the feasibility of promotion
