[description]
(I) explain the technical difficulties and technical barriers of high-quality packaging box equipment in combination with the production process of the product and the source of key parts
1. Production process
The production processes of high-quality packaging box equipment mainly include product design, machining, assembly, programming and input. Among them, the process links that can best reflect the technical difficulties and technical barriers of high-quality packaging box equipment are product design, programming and input. The specific circumstances are as follows:
(1) R & D design
The company independently designs the high-quality packaging box equipment. Based on the market demand, through the overall scheme design and review, the task framework of software, hardware and structure development is clarified, and then the functional departments of the company's technology R & D center carry out the detailed design. For the research and development of new models, new processes and new applications of high-quality packaging box equipment, the company has accumulated rich experience and a large number of equipment structure drawings after nearly 20 years of research and development activities, and can quickly complete the product design that can meet the needs of customers. The above experience and drawings are acquired by the company through induction, summary and accumulation in the long-term R & D practice of high-quality packaging box equipment, which is difficult to replicate and technically difficult.
The core components of high-quality packaging box equipment mainly include box blank gluing parts, gluing parts, suction and delivery paper parts, positioning parts and forming parts. Each core component is a necessary part to realize the automatic production of high-quality packaging box. The company has obtained 264 patents for the shape, structure and purpose of the main components of each core component; For the software system of each core component, the company has obtained 62 software copyrights. In the R & D and design process of high-quality packaging box equipment, the company can directly carry out the development and technical upgrading of new models on the basis of long-term accumulated experience, structural drawings, patents and software copyrights. It is difficult for other enterprises to break through the 264 patented technologies and 62 software copyrights obtained by the company in a short time.
Therefore, the company has strong technical barriers in the R & D and design of high-quality packaging box equipment. (2) Programming and input
A large number of software control programs need to be compiled and entered in the high-quality packaging box equipment, which is the key to ensure the safety and effectiveness of the equipment. The high-quality packaging box equipment uses a large number of parts and sensors, and the system structure is complex. The control system needs to coordinate and control the operation of each subsystem, realize the management and control of action sequence, box making mode and functional modules in the production process of high-quality packaging box, and accurately control the glue viscosity and temperature, forming size, positioning accuracy, box making mode and other parameters. The equipment needs to have a perfect alarm system, In case of abnormal conditions, ensure the safety of the operator and provide human-computer interaction in various states. These core software of the company are the R & D achievements summarized according to the experience of the company's high-quality packaging box equipment in recent 20 years, which requires a lot of R & D investment and technical accumulation, and has high technical difficulty.
Part of the control software of the company's high-quality packaging box equipment has formed core technologies such as multi-mode molding box making technology and parametric intelligent adjustment technology. It has certain technical barriers to apply for and obtain relevant software copyright. The software copyright corresponding to each main functional component is as follows:

2. Key parts
The company's automatic packaging equipment is mainly composed of box blank gluing parts, gluing parts, suction and delivery paper parts, positioning parts and forming parts. Each part is also composed of Feida cam mechanism, silk screen gluing mechanism and other key parts formed by a wide variety of standard parts, non-standard parts, electrical components and other raw materials through assembly and other processes, and embedded software. The technical difficulties and technical barriers of key parts are as follows:
Technical difficulty and technical barrier of key parts
(1) Due to the small thickness and size of the face paper for the production of high-quality packaging boxes, the surface is covered with film and has static electricity, so the Feida suction and delivery face paper is easy to come out
Two or more sheets are sucked at a time, and the surface of tissue paper is curled. In order to solve the above problems, the company has adopted the trigger. The company has obtained a suction cup face paper feeding mechanism and a suction turnover paper suction structure. After the suction cup sucks the front end of the face paper, it can automatically turn 90 ° paper and turnover mechanism by using the pressure difference inside and outside the paper suction cavity, And Hongming machine moving Feida convex machine to separate the upper and lower paper; Trajectory Operation Control Software v1 0. Hongming machine glue blocking control mechanism (2) in order to achieve the production target of 48pcs / min, Feida needs to transport 48 sheets of tissue paper per minute, and the conveying speed of tissue paper is higher than that of Software v1 0 and other software copyrights, with high speed, prone to unstable phenomena such as paper falling. The company adopts self-designed series cam structure, which can accurately control technical barriers.
The sequence and time parameters of each action of facial paper suction and delivery can reduce the impact force of Feida during high-speed operation and ensure the suction and delivery surface of Feida
Smoothness and stability of paper process.
In order to realize the three-dimensional feeling and exquisite degree of the surface of the high-quality packaging box of mobile phones and other electronic products, the card needs to be pasted on the face paper, and the card pasting position company has formed technologies such as silk screen printing and local gluing, so it is necessary to realize local gluing. The traditional roller glue passing method can only pass the whole surface
