Needle type vacuum pumping and heat seal coding device used for pure electric shaping packaging machine

Abstract

The invention discloses a needle type vacuum pumping and heat seal coding device used for a pure electric shaping packaging machine. A bag body seal coding system is arranged at the lower end of a needle suction type bag body vacuum pumping system, the bottom end of a strip-shaped needle type ventilation pipe in the needle suction type bag body vacuum pumping system can be inserted into a bag body and makes contact with the surface of tea leaves in the bag body, a bag opening of the bag body and the strip-shaped needle type ventilation pipe inserted into the bag body can be clamped by a seal strip mechanism in the bag body seal coding system at the same time, when the vacuum pumping procedure of the bag body is finished, the bottom end of the strip-shaped needle type ventilation pipe in the needle suction type bag body vacuum pumping system is pulled out upwards and enters the tea foam blowing work, and the bag body seal coding system carries out dual-side heat seal and date code coding work on the bag opening of the bag body subject to vacuum pumping work finally. The device has the beneficial effects that the structure is novel, the vacuum pumping speed of the bag body is higher, vacuum pumping is more thorough, the expiration date of filler in the bag body is longer, the tea foam blowing effect is ideal, and the practicability is higher.

Description

technical field [0001] The invention relates to an improvement of a packaging machine, which is mainly used for the packaging of strip-shaped, granular, and powdered foods such as tea, wolfberry, and medicinal materials, especially for the packaging of tea, and particularly relates to a pure electric plastic Needle-type vacuum pumping and heat-sealing coding devices for packaging machines. Background technique [0002] The applicant of this patent applied for an invention patent named "A Pure Electric Plastic Packaging Machine" on April 26, 2017 (patent application number: 2017102840801). Vacuum and double-sided heat-sealing device, in the external vacuum and double-sided heat-sealing device, the fixed silicone module of the right vacuum chamber in the state of moving to the left can slowly move closer to the direction of the fixed-sealing copper module of the left vacuum chamber, and the opposite right vacuum chamber The fixed silicone module and the fixed sealing copper m...

[0002] The applicant of this patent applied for an invention patent named "A Pure Electric Shaping and Packaging Machine" on April 26, 2017 (patent application number: 2017102840801). Vacuum and double-sided heat-sealing device, in the external vacuum and double-sided heat-sealing device, the fixed silicone module of the right vacuum chamber in the state of moving to the left can slowly move closer to the direction of the fixed-sealing copper module of the left vacuum chamber, and the opposite right vacuum chamber The fixed silicone module and the fixed sealing copper module of the left vacuum chamber can clamp the bag opening of the bag body. At this time, the first chamber and the second chamber are combined to form an external vacuum chamber, and a complete vacuum chamber is formed under the action of the sealing ring. A sealed airtight chamber, the pocket of the bag body is now inside the outer vacuum chamber, and the PLC controls and drives the vacuum solenoid valve to control the vacuum pump to pump the air inside the outer vacuum chamber out of the vacuum chamber. The vacuum port is pulled out to achieve the purpose of vacuuming the bag body by means of external vacuum pumping. However, since the bag mouth is completely pressed by the right vacuum chamber fixed silicone module and the left vacuum chamber fixed sealing copper module, plus There will still be gaps when the irregularly shaped tea leaves in the bag are close to each other, so when the vacuum pump pumps out the air in the outer vacuum chamber, the gap between the right vacuum chamber fixed silicone module and the left vacuum chamber fixed sealing copper module The pressure against the top will cause the air in the bag to be pumped out incompletely, so that there will still be a small amount of air inside the sealed bag

[0003] In order to achieve a faster and more ideal vacuuming effect, through improvement, the needle-suction bag vacuum device is used to vacuum the bag, but the long needle-type ventilation tube in the needle-suction bag vacuum device Problems with inhaling tea foam when doing pumping operations

[0004] The "pure electric shaping and packaging machine" also provides a bag taking and coding device. The coding device in the bag taking and coding device adopts a direct heating coder, and the direct heating coder is tightened by screws. It is fixed at the rear of the outer bag box, and the bag taking mechanism will remove the bag stacked in the outer bag box. After the date is heat-stamped on the bag body by a direct thermal coder, the bag taking mechanism will change the direction of the bag body Transported to the target position for the opening process of the bag body, this kind of direct heating coder will have problems in the actual application process, such as high cost, frequent replacement of ribbons, unstable operation, and high maintenance costs
