Automatic end sealing device for large-scale coil stock peripheral coating film

Abstract

The invention provides an automatic end sealing device for a large-scale coil stock peripheral coating film. The automatic end sealing device for the large-scale coil stock peripheral coating film comprises an end sealing rack, a coil stock positioning delivery mechanism, a heat-sealing device, a horizontal feeding device and a negative pressure suction film device, wherein the coil stock positioning delivery mechanism, the heat-sealing device, the horizontal feeding device and the negative pressure suction film device are installed on the end sealing rack; the end sealing rack comprises a table rack and a mounting rack, the top of the table rack is open, the mounting rack comprises a horizontal beam which is arranged above the top of the table rack, peripheral-coating-complete coil stocks can roll and pass the space defined by the mounting rack and the table rack, and the direction of the horizontal beam is parallel to the axial direction of the coil stocks.

Description

technical field [0001] The invention relates to an end sealing device of a packaging line, in particular to an end sealing device for a large cylindrical product. Background technique [0002] The existing automatic plastic film end-sealing packaging mechanism is mainly small-scale packaging machines, which are generally used in small-scale product automatic packaging production lines for hot-air packaging. requirements, while the medium-sized sealing mechanism is generally used for simple sealing after filling production. For large roll material products such as non-woven cotton rolls, when the end face sealing process (referred to as end seal) is performed after the circumference is wrapped with plastic film, since the thickness of the roll material can reach 2-75mm, the diameter of the large roll can reach close to 1m, and the coil width can reach about 1.5-2m. The existing automatic packaging equipment cannot automatically end-seal the circumference of the film. Howeve...

[0002] The existing automatic plastic film end-sealing packaging mechanism is mainly small-scale packaging machines, which are generally used in small-scale product automatic packaging production lines for hot-air packaging. requirements, and the medium-sized sealing mechanism is generally used for simple sealing after filling production

For large roll material products such as non-woven cotton rolls, when the end face sealing process (referred to as end seal) is performed after the circumference is wrapped with plastic film, since the thickness of the roll material can reach 2-75mm, the diameter of the large roll can reach close to 1m, the coil width can reach about 1.5-2m, and the existing automatic packaging equipment cannot automatically end-seal the circumference of the film

When manual end sealing is performed, due to the large volume of the coil material, multiple people are required to cooperate, and the quality of the end sealing is poor, and the packaging pass rate is low.

[0003] The Chinese patent No. 201210464731.2 discloses a plastic film sealing machine. After the product is packaged artificially, it is continuously heated by the electric heater, and the plastic sealing process is artificially controlled by the pedal. Such a sealing mechanism is only suitable for small Products, low degree of automation, low efficiency, no way to guarantee product sealing quality, this mechanism is only suitable for small enterprises with low automation production lines, not practical for large products
