Forming machine, also known as open-box machine, refers to the automatic completion of open-box, forming, bottom folding. At present, the lower part of the tape is pasted, the folded cardboard boards are opened, the bottom of the box is folded according to the relevant procedures, and sealed with tape and conveyed to the special equipment of the packing machine. Automatic carton forming machine and automatic carton opening machine are the pipeline equipment for automatic carton opening, automatic folding lower cover and automatic sealing lower tape. All the machines are controlled by PLC + display screen, which is convenient to operate and indispensable for automatic large-scale production.

The working principle of the moulding machine is similar to that of the injector for injection. It uses the thrust of the screw (or plunger) to inject the plasticized melted plastic (i.e. viscous flow) into the closed die cavity and solidify it to obtain the process of the product.

Injection molding is a cyclic process, each cycle includes: quantitative feeding - melting plasticization - pressing injection - filling cooling - opening parts. After removing the plastic parts, the mould is closed again for the next cycle.

structure

(1) The main computer chip of imported PLC is selected for the forming machine, matching LCD screen, software standby fault self-diagnosis system and fault correction function to make the operation more convenient. Its control program is planned foolishly and can be operated on duty without professional training.

(2) The full hydraulic drive of the forming machine has the domestic first stepless hydraulic frequency modulation technology, which handles the habit of the forming machine to various materials and blocks, advances the density of materials and shortens the forming cycle.

classification

According to the product series, it can be divided into: carton forming machine, carton forming machine, carton filling machine, carton filling machine, carton filling machine, carton unloading machine, etc.

According to the degree of automation, the machine can be divided into: automatic forming machine, automatic carton forming machine, etc.

characteristic

Vertical storage cardboard method is selected and can be replenished at any time without shutdown.

It is suitable for the same carton standard packaging at the same time. When changing the carton standard, it should be adjusted manually (it only takes 1 to 2 minutes).

The machine adopts rational planning, suction box, forming and bottom sealing are automatically handled while the iron is hot.

The machine has fine and durable performance, no vibration in operation process and long working stability and life.

This machine is controlled by PLC + man-machine interface display screen, with high performance, high speed and high power.

The folding angle length of the sealing tape at both ends of the carton is 50-70 mm, which can be customized to 80, 100 MM.

It can be operated on a single machine or matched with automatic packaging line.

advantage

_Compared with traditional clay brick machine, industrial waste slag can be selected as main materials: fly ash, coal gangue, slag, slag and various tailings. More environmentally friendly, more energy-saving, waste recycling and reuse.

_Block forming machine uses three bars to press up and down once, which can be stacked immediately after forming without a supporting brick board. It is a new type of block brick in China at present.

_The cost of the standard brick produced by the block forming machine is low and the profit is rich. The cost of each standard brick is 9 cents, and the market price is 2-3 times that.

_Block forming machine body is made of high precision, high strength castings and special welding technology and materials. It has good steel, vibration resistance and long service life.

_The block moulding machine adopts hydraulic pressure moulding with bench mode combined vibration and reciprocating guiding feeding equipment. The moulding cycle is short, the output power is high, the quality of the block is compact, the strength is high, and the standard is accurate.

_The block forming machine adopts the technology of mechanical, electrical and hydraulic integration to make every cycle process of equipment work consistent, so that the forming output value is high and stable, and the rejection rate is low.

_Block forming machine is a multi-purpose machine. By replacing the mould, we can produce different standard porous bricks, hollow blocks, curb stones, pavement bricks, grass-planting and tree-planting bricks, grid bricks and other cement products.

_Programming can be made according to production demand, and manual, semi-automatic and full-automatic operation can be completed.

I. Operating Principle of Fully Automatic Disc Plastic Injection Molding Machine

Fully automatic disc plastic injection moulding machine for shoemaking enterprises is the most common equipment in shoemaking enterprises, called electric tiger. China is a big shoemaking country with many shoemaking equipment.

Mechanical features of fully automatic disc plastic injection moulding machine (hereinafter referred to as disc moulding machine):

This machine is specially used to produce all kinds of monochrome, bichrome and trichrome sports shoes, leisure soles, boys and girls soles and other products.

_Material is suitable for producing foam and other thermoplastic materials, such as PVC, TPR, etc.

This machine is controlled by computer program (single chip computer, PLC). The control of main and auxiliary machines is accurate, the operation is simple and the maintenance is simple.

The layout of pressure switch for master cylinder of die closing can quickly close the die and establish the clamping force, so that no rough edge can be formed every time, and the product quality can be guaranteed.

Proportional pressure control, independent operation of injection pressure of each mould, suitable for production of products with different injection volume.

II. Power-saving Principle of Disc Machine

Because there is a very violent catastrophic process in the process of disc machine operation, the impact on the machine is very large, affecting the life of the entire injection system. At present, there are many old equipment in domestic shoemaking enterprises, which have low degree of automation and high energy consumption. Machines are usually planned according to larger production capacity. In fact, they often use less power when they are produced. The speed of the oil pump motor remains unchanged, so the output power is almost unchanged. There is a phenomenon of big horse trolley in production. So a lot of energy is wasted.

We choose the frequency conversion technology of the disc machine. The real-time detection of the frequency converter comes from the pressure and flow signals given by the computer board of the disc machine. The pressure or flow signals of the disc machine are 0-1A.
