The automatic box packing machine mainly adopts a series of complex transmissions, imitating human actions to automatically pack food, medicine, health products, and instructions into corresponding boxes, automatically completing the process of box insertion, opening, filling, and closing. Some fully functional automatic box packing machines also have additional functions such as sealing labels or heat shrink wrapping. Compared with manual boxing, automatic boxing machines can simplify these complex processes. Automatic boxing machines are now widely used, greatly improving work efficiency and saving labor costs.
However, although automatic box packing machines are time-saving, labor-saving, and efficient, improper or erroneous operation can also lead to some problems. For example, sometimes slight changes in the size and dimensions of the cardboard box can cause it to be difficult to open or jam the machine; The stability of the machine is relatively poor after long-term high-speed operation, and stable operation is required, which requires the use of servo systems more often; After long-term operation, the accuracy cannot meet the requirements, and the synchronization is poor, so reliability needs to be improved; If the reliability of the machine operation is not high, timely maintenance is necessary to avoid affecting the production schedule.
Therefore, it is necessary to promptly address the existing problems and be familiar with the workflow of the automatic box packing machine. According to professionals, the operation of an automatic box packing machine is usually divided into four stages: placing the box, opening the box, loading, and finally closing the box, and then completing the entire process. Firstly, the material is fed onto the conveyor belt by the feeding device, and then a photoelectric switch is installed on the conveyor belt to detect whether the product meets the requirements. If it does not meet the requirements, the instruction manual will not be issued and the box will not be sucked. If the requirements are met, the PLC will transmit the command to the suction box machine.
Secondly, generally speaking, the lower box action is carried out by a suction cup sucking a paper box from the paper box feeding port and transporting it to the main production line for packaging. The paper box is fixed by a guide rail slot and opened by a push plate. At the same time, two forward movable slots are lifted from below to clamp the side of the paper box from the front and rear directions, making the box open at a right angle and move forward to the loading area to wait for material loading.
In addition, after filling the materials and other accessories in the loading area, the relevant devices will push the box into the left and right guide rails, and then perform the box covering action. It is worth noting that before covering the box, the machine will first bend the tongue of the paper box, and then a push plate will push the box cover to bend, so that the tongue can be inserted into the box and the lock buckle can be fastened. The action of closing the box is a crucial one, and the quality of completion is closely related to the structure of the paper box and the accuracy of machine adjustment. Otherwise, the improper sealing action will directly affect the packaging effect.
Finally, when the food and instructions are accurately pushed into the box, the paper box will continue to move forward under the drive of the box chain. Afterwards, after passing through the batch number printing device, the steel characters are printed and enter the box covering process. It should be noted that there is a "defective product" removal device installed on the export conveyor belt, which can remove all products with problems detected in the previous processes such as food packaging, opening, and filling, in order to better ensure that the resulting food packaging boxes meet the process requirements and are all qualified products.
It cannot be denied that the automatic boxing machine not only improves the efficiency of boxing and saves manual boxing costs for enterprises, but also reduces the error rate of product boxing to a certain extent, ensuring the quality of boxing. However, users need to promptly address any issues that arise during the operation process, while also being familiar with the workflow of the automatic boxing machine to ensure the normal operation of the automatic boxing production line.
