Cutting device of paper-plastic bag cutting and sealing machine

Abstract

The invention belongs to the field of paper-plastic bag cutting and sealing equipment and particularly relates to a cutting device for a paper-plastic bag cutting and sealing integration machine. The cutting device comprises a sliding support and a cutter. The sliding support is connected with a horizontal displacement drive mechanism. The sliding support is formed by connecting an upper plate and a rear plate. A sliding block is installed on the rear plate through a connecting shaft and can slide along the connecting shaft front and back. A front clamping groove and a rear clamping groove are formed in the connecting shaft in the length direction. The cutter is installed on the sliding block. The lowest position of the cutter is lower than the bottom face of the sliding block. The sliding block is provided with a spring locating column. The top end of the spring locating column penetrates the hole wall of a shaft hole of the connecting shaft of the sliding block and abuts against the connecting shaft. The cutting device is ingenious in structural design, the position of the cutter can be adjusted conveniently and fast according to the actual needs, and the paper-plastic bag cutting and sealing integration machine is applicable to traditional paper-plastic bags with the outer sides of the sealing opening positions coded and paper-plastic bags with the outer sides of the sealing opening positions being not coded. Meanwhile, waste of paper-plastic bag materials in the cutting process is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to a cutting device of a paper-plastic bag cutting and sealing machine, belonging to the field of paper-plastic bag cutting and sealing equipment. Background technique [0002] The medical sealing machine is widely used in disinfection medical centers and has the characteristics of continuous sealing. [0003] At present, there are separate paper-plastic bag cutting machines and separate paper-plastic bag sealing machines on the market. In this way, it is necessary to use paper-plastic bags of different specifications and lengths for different disinfection instruments during specific operations. Cutting the paper-plastic bag on the cutting machine, and then taking it to the independent sealing machine for sealing is inconvenient to use, and there are problems such as low efficiency and waste of space. [0004] Subsequently, researchers have developed a paper-plastic bag cutting and sealing machine that integrates cutting and seal...

AI Technical Summary

Problems solved by technology

[0006] Since the paper-plastic bags that need to be sealed are usually coded on the outside of the sealing position, the distance between the sealing position and the edge of the paper-plastic bag is generally 1 to 4 cm, and the position of the cutter in the cutting device is relatively outside, but for For the paper-plastic bag that does not need to be coded outside the sealing line, the distance between the sealing position and the edge of the paper-plastic bag is obviously too large, so that a large amount of paper-plastic bag material will be wasted during the cutting process of the paper-plastic bag

However, due to the fixed position of the cutting device in the traditional paper-plastic bag cutting and sealing machine, it is difficult to adjust the position of the cutter to reduce the distance between the sealing position and the edge of the paper-plastic bag
