Description

Technical Field

[0001] The invention relates to the technical field of special packaging machinery, in particular to an intelligent packaging four-sided edge wrapping machine. Background Art

[0002] In the packaging industry, the application of intelligent packaging equipment is becoming more and more widespread. Among them, the four-sided edge wrapping machine is one of the important packaging equipment, which is mainly used to wrap the four sides of the product to improve the product's aesthetics and protection performance. Traditional four-sided edge wrapping machines are mostly divided into two parts: long side two-sided edge wrapping machine and short side edge wrapping machine. This division of labor has improved production efficiency to a certain extent, but there are also many shortcomings.

[0003] First of all, in the actual production process, many packaging manufacturers often only use the hemming machine parts on both sides of the long side, and use manual hemming for the short side. This method not only increases the labor cost, but also the quality of manual hemming is difficult to guarantee, and it is easy to have undesirable phenomena such as "false hemming" and "bulging hemming", which affects the overall quality of the product.

[0004] Secondly, the existing short edge hemming machines also have some problems in the production process. Due to the relatively complex structure of the short edge hemming machine, it is difficult to debug and requires a high level of professionalism from the operator. This not only increases the debugging time and cost, but also easily causes problems in after-sales service, bringing additional burdens to the manufacturer.

[0005] In addition, the existing four-sided hemming machines still have some shortcomings in their overall structure. For example, the connection between the long-side and short-side hemming machines is not smooth enough, which makes the product prone to deviation during the transmission process, affecting the hemming effect. At the same time, the degree of automation of some equipment is low and requires manual auxiliary operation, which not only reduces production efficiency but also increases the labor intensity of operators.

[0006] In view of the above problems, the market is in urgent need of a four-sided edge wrapping machine that can overcome the shortcomings of the existing technology. The equipment needs to have the advantages of compact structure, simple debugging, high degree of automation, and good edge wrapping effect to meet the packaging industry's demand for high-quality and high-efficiency packaging equipment. Therefore, this technical solution proposes an intelligent packaging four-sided edge wrapping machine, which aims to solve the problems existing in the existing technology and improve production efficiency and product quality by optimizing the equipment structure and improving the degree of automation.

Under the support of 47, the lifting and lowering paper pressing board 53 is pressed on the upper part of the short side of the product.

[0023] When the four-sided edge machine is working: Step 1: The front assembly line transfers the positioned and overlapped grey board and face paper (hereinafter referred to as "face paper") to the belts of the two wrapping devices. The belts transfer the products through the two-side devices to complete the long-side wrapping action.

[0024] Step 2: After the product completes the long side action, it is continuously transmitted to the suction line of another short side hemming mechanism. The suction line transmits the product to the positioning position. After completing the positioning action, the corner pinching mechanisms on the four corners on both sides are activated to complete the four-corner pinching and hemming. The suction cup turns on the vacuum and descends to suck the product after the positioning and pinching is completed. After it is lifted to a certain height, the horizontal suction cup transmission mechanism transmits the product to the short side hemming mechanism position.

[0025] Step three; after reaching the position of the short side hemming mechanism, the lateral suction cup transmission mechanism descends to place the product on the short side folding platform, and at the same time, the pressure plate on the upper part of the product presses down to press the product tightly on the folding position. After the vacuum of the lateral moving suction cup is turned off, it rises and resets to the initial material suction waiting position. Under the action of the rising folding mechanism, the product completes a 90-degree folding action, and under the action of the forward movement of the folding mechanism, a second 90-degree folding action is completed. The folding mechanism presses down to make the product fit more tightly. After the downward pressing action, the folding mechanism rises and moves backward. While the folding mechanism descends, the pushing belt pushes the folded product into the bubble pressing roller. The product is discharged after passing through the bubble pressing roller, and the entire folding process is completed.
