摘要

塑料瓶自動(dòng)封口機(jī)是一臺(tái)用于飲料或化工產(chǎn)品的塑料瓶自動(dòng)封口設(shè)備，包括輸送裝置，封口裝置，封口膜退繞卷取裝置以及切膜裝置。塑料瓶置于傳送帶上，輸送帶通過(guò)伺服電動(dòng)機(jī)控制塑料瓶在封口工位、切膜工位停止；封口裝置采用氣缸控制，熱封口器采用采用發(fā)熱管進(jìn)行加熱，通過(guò)溫控開(kāi)關(guān)進(jìn)行溫度控制，通過(guò)熱封口板與瓶口的壓合進(jìn)行熱封。封口膜退繞卷取裝置包括封口膜退繞裝置和封口膜卷取裝置，封口膜退繞裝置通過(guò)滾動(dòng)軸承固定在機(jī)架上，封口膜卷取裝置通過(guò)步進(jìn)電機(jī)和同步帶輪，通過(guò)步進(jìn)電機(jī)控制封口膜有時(shí)序的轉(zhuǎn)停進(jìn)行退繞卷取動(dòng)作，即在進(jìn)行切膜、封口工序是停止轉(zhuǎn)動(dòng)，在該工序的間隔時(shí)間進(jìn)行退繞卷操作，從而保證進(jìn)行切膜、封口工序時(shí)熱封口膜處于正確位置；切膜裝置采用熱切膜，有電能進(jìn)行加熱，溫度控制器進(jìn)行溫度控制，將熱封膜進(jìn)行切割。

工作時(shí)，當(dāng)塑料瓶進(jìn)入工作空間后，塑料瓶在傳送皮帶摩擦力的作用下前進(jìn)。當(dāng)塑料瓶輸送到至封口工位時(shí)，伺服電機(jī)將停止轉(zhuǎn)動(dòng)，塑料瓶停在封口工序位，封口裝置進(jìn)行完封口工序以后，伺服電動(dòng)機(jī)將繼續(xù)轉(zhuǎn)動(dòng)，將塑料瓶傳動(dòng)到切膜工序位置，伺服電動(dòng)機(jī)停止轉(zhuǎn)動(dòng)，氣缸控制切膜壓板下壓，進(jìn)行切膜工序，切膜完成以后，伺服電動(dòng)機(jī)控制傳送帶繼續(xù)轉(zhuǎn)動(dòng)，將塑料瓶輸送到下一工序，同時(shí)，封口膜退繞卷取裝在步進(jìn)電機(jī)控制下進(jìn)行退繞轉(zhuǎn)運(yùn)動(dòng)，退繞到指定位置以后，伺服電動(dòng)機(jī)停止。

該塑料瓶自動(dòng)封口機(jī)方案，封口平穩(wěn)、經(jīng)濟(jì)、快速。這次設(shè)計(jì)的塑料瓶自動(dòng)封口機(jī)，可以應(yīng)用于工廠流水線進(jìn)行大規(guī)模的生產(chǎn)，提高工廠的生產(chǎn)效率。

Abstract

Plastic bottle automatic sealing machine is a for drinks or chemical products of plastic bottle automatic sealing equipment, which comprises a conveying device, sealing device, sealing film unwinding coiling device and film cutting device. Plastic bottle is arranged in the transmission belt, conveyor belt through the servo motor control plastic bottles in the sealing station, cutting film station stop; sealing device is controlled by an air cylinder, heat sealing mouthparts using heating tube heating, through the temperature control switch for temperature control. Through the thermal sealing pressure plate and the bottle is heat sealed. Can turn into the sealing film unwinding coiler device comprises a sealing film unwinding device and a sealing film coiling device, sealing film unwinding device through the rolling bearing is fixed on the machine frame, sealing film coiling device through the stepper motor and the synchronous belt wheel, the motor control sealing film sequence stop unwinding coiler action, namely the cutting film, sealing process is to stop rotation, in the process of interval unwinding roll operation, so as to ensure the cutting film, sealing process heat sealing film is in the correct position, cutting film device with eager film, electric heating, temperature controller temperature control, heat sealing film cutting.

When working, when plastic bottles into the working space, the plastic bottle forward on the conveyor belt under the action of friction force. When the plastic bottle conveying to the sealing station, servo motor will stop running, plastic bottle stopped in the sealing process a, sealing device after sealing process later, servo motor will continue to rotate, plastic bottle drive to cut position of membrane process, servo motor to stop rotating, gas cylinder control film clips, under pressure, cutting process film, cut after the completion of the film, the servo motor control conveyor belt to rotate, the plastic bottles will be transported to the next process. At the same time, sealing film unwinding roll device in the stepper motor control of unwinding rotary motion, unwinding in the specified location, servo motor stop.

The plastic bottle automatic sealing machine, sealing, stable, rapid economic. Automatic sealing machine for the design of the plastic bottles can be used in the factory assembly line of large-scale production, improve the production efficiency of the factory.
