5. Main structure and function:
The whole set of equipment consists of bottle feeding conveyor belt, packaging machine, heat shrink machine, non-powered conveyor roller, electrical control, pneumatic control and other parts.

(1).Packaging Machine

The packaging machine is mainly composed of a frame, a bottle separating mechanism, a bottle pushing mechanism, a film placing mechanism, a film wrapping mechanism, etc.

1). The bottle feeding mechanism is responsible for conveying the PET bottles to the bottle separation mechanism, which is divided into two parts: front conveying and rear conveying.
2). The bottle separation mechanism is responsible for sorting the PET bottles according to the packaging requirements so as to realize the film wrapping.
3). The bottle pushing mechanism is responsible for pushing the grouped PET bottles forward and wrapping them with film.
4). The film unwinding is responsible for supplying the film to wrap the grouped PET bottles.
5). Film wrapping: The supply length of the shrink film is automatically set according to the size of the package, and the automatic film wrapping is completed synchronously during the forward movement of the product.

(2) Heat shrink machine
The heat shrink machine consists of three parts: heating and shrinking, cooling and shaping, and product conveying.

1). Heating and shrinking:
The shrinking machine heats and shrinks the wrapped package, so that the film shrinks evenly at the set temperature, adheres closely to the surface of the package, and wraps the package tightly to achieve the desired packaging purpose.
The temperature controller uses a digital display temperature controller with a built-in PID function. The temperature sensing is sensitive and accurate and can be set at will. During operation, the temperature of six parts in the heat shrink furnace cavity is detected by thermocouples, and the heating state of the heating tube is automatically adjusted to ensure that the heating temperature in the furnace cavity is constant within the set temperature range.
The air volume and pressure of the furnace can be controlled by variable frequency regulation. During operation, the heat of the heating tube is blown out from the two side walls and bottom of the heat shrink furnace cavity through the centrifugal fan, and acts on the wrapped product. This equipment has a total of 6 fans, each of which is composed of an extended shaft motor customized by our company and a special multi-wing centrifugal impeller. According to the running direction of the equipment, every two fans correspond to a heating zone and forming zone. According to the hot forming process of the wrapped product, the fan speed of each heating forming zone can be set by frequency conversion to achieve the required air volume and air pressure for forming.
The air volume and air outlet position in the heat shrink furnace can be adjusted at will. According to the hot forming process of the wrapped product, the air volume and air outlet position of a certain section of the heating forming zone can be adjusted by mechanically adjusting the inner wall of the furnace cavity and the bottom air volume adjustment plate.
The film package can be shared by single and double channels. This machine is used as a double-channel film package, and a hot air plate is configured in the middle of the heating furnace channel. The heat is more uniform when the double package passes through the heat shrink furnace. When used as a single channel, the middle hot air plate in the heating furnace channel needs to be removed.
Make corresponding modifications according to customer requirements.
The required packaging temperature is 200°~280°, the heating time is 30-40min, the heating tube power is 97.2Kw, and the outer wall temperature of the heating furnace is 30°~50°.
2). Cooling and shaping:
Cooling and shaping is responsible for rapidly cooling the film on the surface of the heated and shrunk packaging, so that the film quickly becomes a high-strength state for easy handling.
The outlet of the heat shrink furnace is equipped with 6 sets of cooling fans, and the perforated mesh belt is used for conveying, which can quickly cool the wrapping film and form a high-strength state.
3). Product conveying:
The stainless steel conveyor mesh chain has a tight and uniform mesh spacing, high mesh strength, stable transmission, and high wear resistance; the machine can be independently controlled, and the motor speed can be adjusted by frequency conversion to match the speed of the main machine of the film wrapping machine.
The fully packaged items are conveyed to the unpowered conveyor roller; the unpowered conveyor roller can play a role of temporary storage, which is convenient for personnel to stack or carry.

7.Peiyu equipment technical advantages

The air volume on both sides of the Peiyu shrinking furnace is adjustable, the air volume at the bottom of the shrinking furnace is adjustable, and the shrinking furnace outlet of the film wrapping machine is equipped with a 4-meter-long cooling conveyor as standard. After shrinking, the packaging looks beautiful, the shrink holes on both sides of the packaging are round or oval without obvious wrinkles, the color film is aligned, the upper and lower deviations are ±5mm, and the left and right deviations are ±5mm.

(1) Control advantages:
Pei Yu independently developed the underlying software, and PLC, servo motor, inverter, etc. are selected from Huichuan brand products, which are not limited by the delivery period of imported brand electrical components. Through the underlying development of the electrical program, the software operation is more convenient, and the program can be adjusted online when the equipment is running, without stopping to find parameters, which improves the operating efficiency of the single machine and the entire line. The control system provides a two-year warranty.
If the customer has other requirements, the accessories can be replaced under the premise that the delivery period is controllable.
(2) Mechanical design advantages:
The bottle feeding conveyor is responsible for conveying the cans/bottles to the bottle separation mechanism. The conveyor belt adopts the Regina 610 series mesh belt. The fully enclosed top surface can provide excellent product support, avoid bottle fall, and is durable; at the same time, the use of a small pitch mesh chain is more conducive to the smooth transition of the product at the conveying end. The control and the main machine form a pressure-free conveying relationship, which is conducive to the bottle group arrangement. The swing cylinder buffer component makes the bottle feeding smoother. The bottle feeding conveyor is divided into two sections, front conveyor and rear conveyor, which can effectively relieve the pressure of bottle feeding.

The PLC adopts the products of Huichuan series, and uses independent servo motors to control bottle separation, film application, film cutting and film wrapping, ensuring the accuracy of bottle separation and film cutting, which can be adjusted according to the packaging specifications of different products. The film application adopts the pre-cutting method, which makes the film application operation more stable and can realize the color film positioning packaging.
