Sealing machine

Abstract

The invention discloses a sealing machine, which comprises a base and a conveying belt which is arranged on the base. The sealing machine comprises a sealing device and a lift regulating device, wherein the sealing device is arranged on the base; and the lift regulating device is used for regulating the sealing device to rise and fall. The sealing device comprises a knife rest and a sealing main shaft, wherein the knife rest consists of an upper knife rest and a lower knife rest; the upper knife rest is provided with a sealing knife; the lower knife rest is provided with a knife holder; the sealing main shaft is provided with a swing arm used for regulating the upper knife rest and the lower knife rest to be separated and reunited; the upper knife rest, the lower knife rest and the sealing main shaft are located on the same vertical line of a. same vertical plane; the upper knife rest, the lower knife rest and the sealing main shaft are entirely connected by adopting a bolt through a sealing mounting plate and the base; the lower end of the bolt is fixedly provided with a drive sprocket; the lift regulating device comprises a handle, a rocker, a drive chain and an air cylinder; both ends of the rocker are respectively connected with a center hole of the handle and a center hole of a driving sprocket of the drive chain; and the air cylinder is used for controlling the drive chain so as to do a lever motion by taking the rocker as the fulcrum, and therefore, the drive chain is meshed and separated from the drive sprocket. The sealing machine disclosed by the invention is high in sealing precision and goof in sealing stability.

Description

technical field [0001] The invention relates to a sealing device, in particular to a sealing machine. Background technique [0002] In the existing sealing machine, the upper knife rest, the lower knife rest and the sealing spindle are not on the same axis on the vertical plane. If the endpoint of the upper knife rest or the sealing knife is point A, the endpoint of the lower knife rest or knife rest is B. Point, with the end point of the sealing main shaft as point C, that is to say, in the prior art, it is difficult to ensure that the three points A, B, and C are in a straight line. In terms of specific structure, the knife rest and the knife rest bearing seat are not integrally formed, but the knife rest and the knife rest bearing seat are connected together with screws, and the knife rest bearing seat is assembled on the seal where the sealing knife and the knife seat are separated. Guide post, so that the knife rest moves up and down with the sealing guide post as the ...

Problems solved by technology

[0002] In the existing sealing machine, the upper knife rest, the lower knife rest and the sealing spindle are not on the same axis on the vertical plane. If the endpoint of the upper knife rest or sealing knife is point A, the endpoint of the lower knife rest or knife rest is B. Point, take the end point of the sealing spindle as point C, that is to say, in the prior art, it is difficult to ensure that the three points A, B, and C are in a straight line

In terms of specific structure, the knife rest and the knife rest bearing seat are not integrally formed, but the knife rest and the knife rest bearing seat are connected together with screws, and the knife rest bearing seat is assembled on the seal where the sealing knife and the knife seat are separated. Guide post, so that the knife holder moves up and down with the sealing guide post as the track. This structure cannot ensure that the upper knife holder, lower knife holder and sealing spindle are on the same axis, so the sealing accuracy is not enough.

[0003] In addition, in the existing sealing machine, the structure for adjusting the lifting of the knife rest and the sealing device are connected together to form a whole, and they are not separable and jointed. Such a structure increases the weight of the sealing part and makes the motor load of the sealing Larger, which affects the stability and accuracy of the sealing action
