Description

Strip package following cutting device

Technical Field

The invention relates to the field of packaging equipment, in particular to a strip pack following and cutting device.

Background

At present, a multi-row continuous strip pack or continuous packaging machine mostly adopts a rolling cutting-off cutter to cut off or adopts an up-and-down tracking type cutter. The hobbing cutter has high processing cost, extremely high processing difficulty after the equipment width is increased, and is easy to generate rigid deformation; meanwhile, in the using process, once foreign matters fall into the device, the device needs to be integrally repaired or directly scrapped, and a user manufacturer generally does not have the repair skill, so that the production efficiency is greatly influenced. The cutter is normally tracked, the upper screw rod and the lower screw rod are driven by independent motors and do reciprocating motion, the cutter is also driven by the independent motors, the size is large, the motion load is high, the discharge of the cut bags is uncontrollable, and the cutter is not suitable for a continuous multi-row strip packaging machine.

For example, chinese patent publication No. CN210556018U discloses a multi-row packing machine for realizing continuous and accurate cutting and a control system thereof, wherein the multi-row packing machine includes a cutting device, a transverse sealing device, a traction device, a longitudinal sealing device and a traction-assisting device, which are sequentially arranged on a straight line at each processing station. The packaging machine further comprises a color code detector, and the color code detector is arranged on the way of conveying the rolled film and is used for detecting the film conveying speed with color codes. The control system comprises a controller, a human-computer interface, a traction servo driver, a cutter servo driver and a traction-assisting servo driver, wherein the controller receives speed and position signals of the transverse seal cutting motor, the traction-assisting motor and the color code detector, and sends action signals or adjustment signals to the cutter servo driver, the traction servo driver and the traction-assisting servo driver so as to ensure that the front cause speed and the rolling cutting speed of the packaging bag are consistent, and simultaneously, the easy-to-tear opening on the packaging bag is cut out synchronously.

Also, for example, chinese patent publication No. CN201006779 discloses a cutting device for strip-shaped packaging bags, which includes a transverse cutting tool holder having a tubular body fixed to one end thereof. The method is characterized in that: the fixed female die is arranged in the positioning groove in the tubular body, the other end of the transverse cutting tool rest is fixed with the cylinder and the movable male die, the connector is used for adjusting the combination or separation of the male die and the cylinder, and the cylinder pushes the male die to move relative to the female die to punch and cut the transverse sealing opening into a geometric shape. By adopting the structure of the invention, the round-corner strip-shaped packaging bag has more beautiful bag shape and more individuality; when the strip-shaped bag is used, other sample bags cannot be scratched, and the skin of the parts, such as the hands, the face and the like, which are easy to contact, of a user cannot be scratched; the powder material in the bag is easy to pour out.

Further, as disclosed in chinese patent publication No. CN105775246A, a sealing and cutting knife of a packaging machine is disclosed, wherein the sealing and cutting knife of the sealing and cutting machine includes a transverse sealing and cutting knife, one end of the transverse sealing and cutting knife is bent to two sides to form a first corner knife and a second corner knife, respectively, the other end of the transverse sealing and cutting knife is bent to two sides to form a third corner knife and a fourth corner knife, respectively, and a longitudinal sealing and cutting knife is extended from the third corner knife toward the conveying direction of the conveying platform. The packaging film which is processed by the sealing cutter and is subjected to heat shrinkage is wrapped outside a product without edges, so that the problem that the edges hurt people is solved, the aesthetic feeling of the outer package of the product is improved, and the grade of the product is also improved. The conveying platform of the packaging machine can be vertically arranged or consists of a high-position front conveying belt and a low-position rear conveying belt, so that the production cost can be effectively reduced and the production efficiency can be improved.

In summary, the technical problems to be solved by the present invention are:

when a rolling cutting-off tool is used for cutting off or a common tracking type cutter is used, the processing cost of the rolling cutting-off tool is high, the processing difficulty is extremely high after the equipment width is increased, rigid deformation is easy to generate, in addition, once foreign matters fall into the rolling cutting-off tool in the using process, the rolling cutting-off tool needs to be integrally repaired or directly scrapped, a using manufacturer generally does not have the repairing skill, and the production efficiency is greatly influenced;

in the common tracking cutter, the upper screw rod and the lower screw rod are driven by separate motors and do reciprocating motion, the cutting is also driven by the separate motors, the size is large, the motion load is high, the discharge of strip packages after cutting is uncontrollable, and the common tracking cutter is not suitable for the application of a continuous multi-row strip packaging machine;

the prior art listed above also has no way to realize multi-row continuous processing of rolled films, so how to realize the functions of continuous tracking cutting of equipment, no waste edge, shaped opening (such as round corner, calabash and other shapes) and synchronous punching of easy-to-tear opening.
