Core for high-efficiency high-speed box sealing machine and using method thereof

Abstract

The invention relates to a core for a high-efficiency high-speed box sealing machine. The core is suitable for soft cartons or empty cartons at the same time and can also prevent the folding of adhesive tape and the falling-off of the adhesive tape pasted on the cartons and belongs to the technical field of mechanical equipment. By using the core for the high-efficiency and high-speed box sealingmachine on the packaging production line, the box sealing efficiency is improved, the defective rate of box sealing is reduced, the requirements on carton quality are lowered, and the economic benefits are remarkably increased. According to the core, a second cylinder is adopted to control the tension of return springs of a rear arm wheel so that the spring can have different return forces at different stages. A first cylinder controls the pre-stretching adhesive tape so that the adhesive tape can have different tensions at different stages, so that the above-mentioned functions of the core for the box sealing machine are realized.

Description

technical field [0001] The invention relates to a core of a high-efficiency high-speed or soft carton or empty carton sealing machine and a use method thereof, belonging to the technical field of mechanical equipment. Background technique [0002] Cartons are the most widely used packaging products. Most of the modern mass-produced products adopt assembly line operations, and mechanical equipment is installed in each corresponding part of the assembly line, thereby reducing the labor intensity of workers and improving production efficiency. The back of the assembly line is often equipped with sealing equipment to seal and package products for easy storage and transportation. However, the current production of sealing equipment is often prone to tape wrinkles and tape falling off by itself, resulting in loose boxes, which affect shipments and even lead to the shutdown of subsequent unmanned automated production lines, and the sealing speed is slow, especially when the quality...

Problems solved by technology

One is the problem of the viscosity of the tape. In order to make the tape firmly seal the carton, the greater the viscosity of the tape, the more reliable the sealing is, the better. On the other hand, when the tape is pasted on the carton, the higher the viscosity of the tape Large, the tighter the tape is stretched when the tape is peeled off from the tape roll during sealing, the greater the tension of the tape, the easier it is for the tape to wrinkle, and the easier it is for the tape head to fall off by itself

The less viscous the tape, the less firmly the tape sticks to the carton and the easier the tape comes off

At present, the manufacturer and tape manufacturer are constantly adjusting according to the climate, carton, tape base material, customer requirements and other factors. The effect is poor, the cost is high, and there are many problems.

The second is the contradiction between the recovery force of the forearm wheel and the rear arm wheel. From the perspective of carton sealing, the greater the recovery force of the rear arm wheel, the faster the recovery speed, and the more the rear arm wheel can be attached to the high-speed moving carton. Turn the horizontal plane to the rear side, and stick the tape to the carton normally, but when the restoring force of the spring is greater, the impact force when the carton encounters the forearm wheel will be greater and the pressure forcing the forearm wheel to contract will be greater, causing the carton to shrink. It is easy to be deformed or even damaged, which limits the speed of sealing the carton. The softer the material of the carton or the lack of product filling in the carton, the more serious the problem of carton deformation or even damage

Based on the above contradictions, the current sealing machine can only take into account the two aspects of the contradiction, which limits the improvement of the speed of the sealing machine and the improvement of the quality of the sealing. Frequently adjust and change the viscosity of the tape or even improve the quality of the carton and tape, reduce the speed of the sealing machine, otherwise the problem will be more serious
