Description

Continuous sealing machine for double-layer plastic film

Technical Field

The invention relates to machines for the plastics industry, among which are also extruders, printers, trimmers, raw material mixers and steel mesh assemblers, in particular in connection with sealers.

Background

Machines in the plastics industry have become more efficient and have achieved better performance and accuracy. These features have led to significant advances.

However, like many other industries, the plastics industry needs to be continually innovated, particularly as it falls into crisis due to the increasing trend toward environmental protection, and hopefully, to reduce plastics consumption.

The plastics industry is experiencing an undesirable period of time due to the environmental implications that the production of the plastics industry is a major factor in pollution.

Industry is always advancing to enable us to provide solutions to new needs, we find themselves in a situation where industrial products pollute the environment, and these same products are solutions if we turn to other designs with characteristics that allow us to take care of the earth. This is the case of new machines, which contributes to the industry by allowing the manufacture of two-compartment packages, which allow us to recycle both.

Having agreed around the world with respect to ozone layer and global warming problems, we now have to take care of natural resources such as water, forests and air. If we take care of forests we contribute to reducing global warming, if we can recycle all this can be achieved. The continuous sealing machine for the two plastic films enables the industry to produce environment-friendly products, so that people need to love natural resources and do not pollute the environment.

The machines mentioned below are part of the plastics industry, are part of the state of the art, and have some moderate similarities to continuous double film plastic sealers.

The machine for sealing the portions, divides the film into two pieces, longitudinally seals and inserts the bellows.

This first machine is part of the sealing section, allowing the sealing machine to make bags on two lanes. Its work includes dividing a tubular bag into two times the width.

Sealing with a hot knife, it obtains two tubes simultaneously. The air gun is used for inflating the air ball. The upper roller does not allow air to flow out. A bellows with wooden elements is inserted. The film with double width is opened by an uncoiler and is not moved by a hot knife.

Similar to the continuous sealer for two plastic films, it incorporates a bellows in the tube and an external wood element in the tube.

This machine differs from the continuous sealer in several ways, firstly, the continuous sealer for two plastic films uses two unwinders to hold the two films. Second, it does not divide the film, but rather seals the two sides of the two films longitudinally. Thirdly, it does not blow the balloon to form a bellows, but uses a bellows former after the film is sealed, on the one hand protecting the original tubular bellows, and on the other hand introducing a bellows of a second lattice. Fourth, it produces a two-compartment coil with bellows. Fifth, in terms of efficiency, the continuous double film plastic film sealing machine produces reels on one or two lanes, improving the efficiency of segmentation.

Trimming machine

The rewinder is located after the printing sector, producing the rewinding reels. The work is to film the paper with a cold knife to continuously produce reels with precise production width. It has an uncoiler and a winder.

Similar to a continuous box sealer, it continuously produces reels.

It differs from the continuous sealing machine of two plastic films in many ways. First, the continuous sealer does not film the film, it seals the two films continuously. Second, the continuous sealer does not produce a rolled film, it produces two rolls, both with interlayers. Third, the continuous sealer has two unwinders and two clutch winders, which rest one winder when the other is on, because the clutch motor is easily overheated.

Filling machine

Filling machines are used for packaging cereals and grains. In its original design, it used a device that rendered the sheet material tubular, placed one on top of the other, and sealed longitudinally, of the type that was discontinuous, because the tubular shape stopped filling. The filling door opens, closes when it reaches the filling weight, seals at the top, and cuts and seals the tube at the bottom for the next filling.

Similar to the continuous sealer for two plastic films, it uses one device to make the sheet take on a tubular shape.

It differs from a continuous double film packaging machine in many ways. First, the continuous double film packaging machine packages two films, one film and one tubular bellows. Second, since the membrane is wider than the tubular bellows, the apparatus causes the membrane to assume an arc shape, thus the edges of the membrane and the tubular bellows

The two sides are matched and used for sealing the two films. Third, the sealer is advanced at the same speed as the film, and the seals are continuous. Fourth, it has two unwinders

Disclosure of Invention

The continuous sealing machine for two plastic films performs sealing of two films, one is a film, the other is a tubular object with a corrugated pipe, and the two sides of the continuous sealing machine have the characteristics of high performance, high speed, good performance and high efficiency.

The invention comprises a machine on a main structure, which consists of the following parts: uncoiler, rocker arm, edge aligner, pulling roller system, anti-static pole, special device, motor with gear box linkage, automatic brake, electromagnetic clutch, continuous sealing machine, bellows former, sealing machine cam shaft, forward pulling roller stepping motor, winding rod and paper positioning roller.

To facilitate your understanding, the following is a general description of the operation of the machine. A film spool is placed in the upper unwinder (5) and a tubular film spool with bellows is placed in the lower unwinder (6). The foil film is passed through a system of pull rolls (13) and the corrugated tubular film is passed through a second system of pull rolls (14). In order to avoid negative factors in the sealing process, the unwinders have been unhooked from the main structure (1) because they use an edge alignment system, which produces lateral movements on the unwinder rod to correct the alignment of the film, both unwinders having this system, producing vibrations. In the main construction of the machine (1), there is a device (19) of special function which makes the film take on an arc by placing the edge of the film on the edge of the bellows. The device has three parts, the first part (20) driving the membrane while it takes on an arc. The second section (21) is a stainless steel arcuate tunnel with flat baffles and sealing windows with continuous seals (27) for sealing the film. Finally, the third stage elements (22) form bellows of the new compartment. The film is advanced with the sheet film above the apparatus and the bellows-like tubular film below the apparatus. In front of the machine main structure there is a front pull roll system (31) which keeps the tension of the film constant for good performance in sealing. At the end of the structure is a constant tension retractor (34) with a clutch. The clutch winders are easily overheated so two winders are used, one working and the other resting, to ensure the availability and performance of the machine.

Detailed Description

The double-film continuous plastic film sealing machine is a high-speed, high-performance, high-efficiency and high-yield machine.

The high speed benefits from the stepper motors of the edge alignment system, the anti-static bars, the film positioning rollers and the front pulling rollers, which allows the high precision required for high speed to be achieved, and a continuous double film plastic film sealer allows for an optimal operating speed of 220 meters per minute.

High performance refers to a roller that ensures no seal defects and bellows width, yielding a constant tension roller with optimal properties for the following sections.

High efficiency means that your work increases the throughput in the previous section and in the latter section, the use of rollers of twice the width can increase the efficiency of all sections.

High performance means that two constant tension winding motors with clutches are used to produce two-compartment tubular rolls, both compartments having bellows, so that we can achieve an optimal 24-hour continuous performance with one winding machine while the other is at rest.

Machine part

We will explain which are the components that make up the machine in order to explain its operation in detail.

Machine structure (1)

The machine structure consists of two parts, and the main structure consists of a guide roller, a feeder traction roller, a front traction roller, a component support, a motor support and an uncoiler structure. The structure of the unwinder is unhooked from the main structure, as some of their functions can generate vibrations, affecting the normal operation of the machine.

Uncoiling rods (5) and (6)

The unreeling rod is a steel bar with a baffle plate, and the sheet-shaped and tubular coils are placed on the unreeling rod by using a corrugated pipe. The shield has a threaded safety pin which is adjustable to secure the coil to the rod. One end of the pay-off lever has a toothed wheel for coupling with a magnetic brake, the function of which will be explained later. At the other end there is a split bushing with a safety lock to secure the rod.

A constant tension unwinder (4) with a brake controlled by a rocker arm.

The uncoiler is unhooked from the main body structure, so that vibration can not affect the sealing machine or a subsequent stage, a paper positioning roller and a corrugated pipe forming machine.

The foil roll is placed on a constant tension unwinder with a rocker-controlled brake on top. The bellows reel is placed on a constant tension unwinder with a rocker-controlled brake at the bottom. The rocker arms (9) and (10) ensure a constant tension of the film in such a way that if the tension is reduced, the brake on the reel is activated and if the tension is increased, the reel is released from the brake. Thus, the rocker continuously adjusts the voltage at the membrane input.

Edge alignment system on decoiler bar

For continuous operation, an edge aligner is used to move the rod on which the reel or film roll is placed.

Edge correction is performed on a bed that supports the unwind bar by a double-turn motor and a propeller attached to the bed that moves laterally to the desired side to permanently center the two films.

The edge alignment sensor does not move with the bed.

The sensor uses a reference to move the bed to the right or left for alignment correction to ensure that the edges of the paper and the edges of the bellows match when sealed.

Feed rolls (13) and (14).

The two films were passed independently through the feed rolls. The outer surface of the feeding roller is provided with a layer of vulcanized rubber coating, so that the film can be continuously pulled. They have pressure grading brackets (15) and (16) for adjusting the pressure of the membrane, the pressures on both sides having to be equal. There are two systems of feed rolls, the upper feed roll for sheet film and the lower feed roll for tubular film with bellows.

A sprocket and chain mechanism (18) with a motor (17).

The films must be maintained at a constant linear velocity, which must be equal on both films to ensure sealing, and to ensure this, both drive roller systems must have a constant linear velocity.

The feeders will be connected together by a sprocket and chain mechanism and traction will be provided by a single motor with independent speed control.

Antistatic bar

The antistatic bar eliminates static electricity in the material by generating positive and negative ions, and neutralizing ions in the material to be deionized. They are located at the entrance of the membrane. The electrode rod or the antistatic rod comprises an inductive coupling, so that the static neutralization of the material is realized. Since the films are made of insulating materials, they are electrostatically charged. Static neutralization allows the film to be properly laid on the equipment. Operating voltage: 7000V. Stainless steel emitters on insulating material.

Special equipment (19)

It is a specially designed device for adjusting the film to conform to its edges when sealed and to conform the cold film behavior to the bellows folding requirements. Its position is between the top feed roll and the front feed roll.

The width of the foil is exactly four times the width of the tube plus the width of the bellows because the edges of the foil and tube must overlap to seal, and the device lifts the foil to the arch tunnel where the edges of the foil and the edges of the sandwiched tube overlap at the time of sealing. It is composed of three parts.

A first section of the apparatus, which directs the sheet from the upper feed roll to an arcuate path or feed member (20) of the apparatus. The second section of the device is a stainless steel arched tunnel with flat baffles and sealing windows where the membrane or central element (21) of the device is sealed.

The third part of the device is the element of the bellows or bellows forming machine (22) that forms the new compartment.

Input element of equipment (20)

The first element of the apparatus receives the sheet from the feed roll and places it on an arched tunnel. It receives the slab at the same level as the tubular and brings it to the level of the tunnel. The purpose of this part of the device is to receive a flat plate of the same width and to guide it while forming it into an arc so that the edges of the flat plate are closer to the edges of the tube during this transition. When reaching the level of the tunnel lower end, the edges of the slab coincide with the edges of the tube.

Stainless steel arch tunnel with plane aileron and sealing window (21)

The second element of the device has the shape of a tunnel on which the film is placed. Below the tunnel is a bellows tube, and the two films advance at the same speed. The purpose of this section of the device is to seal the two films on both sides in the unsealed window.

Front of corrugated pipe (22)

The sheet must now be lowered to the same level as the tube and conform to the same width, as it will now have a bellows. This part of the device consists of an inner and an outer part. The inner part of the bellows former ensures the exact shape of the new compartment and ensures that the pressure on the film does not deform the original tube when the bellows is formed. The method is realized by the following steps: in the new compartment, the shape of the compartment is formed by two metal frames.

The peripheral portion uses external fittings of a bellows former (25) through which the bellows is inserted into the new compartment. The peripheral portion uses an external fitting of a bellows former.

(25) Through which the bellows is inserted into a new compartment.

Ladder-shaped metal frame (23)

From the top of the tunnel to the exit of the tunnel, the bellows moulding machine has a trapezoidal metal frame in such a way that the film transitions naturally from the top of the tunnel to the bottom of the apparatus where the original tube is located.

Rectangular metal frame (24)

At the bottom, the bellows former has a rectangular metal frame in contact with the top surface of the original tube, and pressure is applied to it during the formation of the new bellows, which secures it in place.

Bellows joint external accessory (25)

Outside the film, between the two metal frames, the bellows on each side are inserted through the external fittings of the bellows former, which consist of two pieces of wood, pushed in material, similar to the wood conventionally used. The chips do not chip and have a polished surface.

Blade positioning roller (26)

The paper locating roller at the lower end of the arch channel rotates outwards through an independent motor to ensure the position of the paper. They are canvas covered rollers. Canvas is a material used in many applications in the plastics industry. It does not wear and aids in balloon positioning during extrusion by friction. The film positioning rollers position the film by stretching over an arcuate tunnel or central section of the apparatus.

To ensure complete sealing of the new dual-chamber film, the film positioning roller may employ a two-speed motor.

Thin film detection is performed with a capacitive sensor. The capacitive sensors are arranged in three-person units. The capacitive sensor measures capacitance, which is measured by capacitance because the film is made of an insulating material. The capacitance increases with the increase of the film, so the capacitive sensor detects the film.

Three sensors are provided on each side, and two sensors are matched with the sealing width. The outermost or third sensor detects the film on one side and activates a second speed on the drum motor on the other side.

The second speed or acceleration produces a corrective displacement that continuously pulls the film.

Continuous sealing system (27)

The continuous sealing system performs sealing of the film. Its function is to seal the edges of the film and the tubular with bellows on both sides. Its main component is a sealing wheel (27) located in the sealing window. The continuous sealing system consists of the following parts.

Resistive bronze seal wheel (27) thermocouple

Electric heating thermostat

Collector and brush system (29) for sealing wheel support (28) Teflon non-adhesive

Sealing wheel pulley (30) sealing wheel cam shaft sealing base with sealing wheel damping system

Tubular guide plate

A resistive bronze seal wheel (27).

The sealer is a bronze wheel with high relief cross-grains that provides a secure seal. It rotates on an axis and the resistor is cylindrical in shape, in the centre or core of the wheel, where the hole of the resistor has been drilled.

Thermocouple and electric temperature controller

The temperature is adjustable and controlled by a motorized thermostat, by reading from a thermocouple placed in the centre of the wheel. There are two thermocouples, one in each wheel, and two thermostats to control the temperature of each wheel. If the temperature in the sealing wheel rises, the temperature controller will de-energize the resistor, and if the temperature drops, the temperature controller will energize the resistor, thereby maintaining the average temperature in the wheel for film sealing.

Collector and brush system (29)

The collector and brush system provides power to the resistor. The collector rotates with the sealing wheel and has conductive tracks that transmit electricity. The carbon brushes remain stationary on the collector track, thereby transmitting power to the collector, which in turn transmits power to the resistor.

A support (28) for the sealing wheel.

A shaft supporting the sealing wheel (16) and the sealing wheel (16) are used as a support for the sealing wheel.

(17) And rotates with the sealing wheel. It has three main parts. The first part is a supporting sealing wheel; the second section has a resistive cable inside and is connected to a collector that rotates with the shaft. The third part is a pulley supporting a sealing wheel from which the wheel obtains traction. The shaft is connected to a bearing support which serves to support the components. The bracket is an arm with a fulcrum, and the second function of the bracket is to raise the wheel through the action of a cam shaft.

Teflon non-adhesive tape

The sealing wheel uses non-sticky Teflon adhesive tape to realize the control of temperature, pressure, sealing time and other parameters in the operation process of the sealing machine. The teflon tape is non-tacky and therefore does not allow the film to stick to the sealer, thereby achieving stable parameters and continuous operation.

Sealing wheel damping system

The sealing wheel uses a compression spring to ensure contact with the film at high speed. The spring is located on the arm or support of the sealing wheel and acts in two positions of the wheel, namely in contact with the membrane and in a raised position.

Sealing wheel pulley (30)

The sealing wheel must be at the same speed as the film, otherwise the film tears when it comes into contact with the wheel at high temperatures. This can be achieved by using pulleys that obtain traction from the feed roll. The pulleys should be of the same size on the wheels and the feed rolls, two on each wheel, two on one of the feed rolls, each side being connected by a circular section elastic band.

Cam shaft of sealing wheel

It has two positions. The raised position lifts the sealing wheel. When the cam is in the second position, the wheel is in contact with the membrane.

Sealant base and tubular guide plate

As a basis for the sealing film, flat rectangular pieces are used, one on each side of the film, placed between the folds of the bellows of the original tube. In addition to providing support for the sealant, this also prevents the upper pleats from sealing with the lower pleats of the tubular bellows, which would damage this compartment. It can also act as a guide to ensure the correct position of the original tube. These parts are made of aluminium of suitable thickness, rounded at the edges, to prevent them from heating and to improve the displacement conditions of the tubular film.

A front tab roll (31).

At the exit of the special device, the front pull roll system advances at the same speed as the entrance roll and maintains the tension of the film in the barrier.

A front pull roller system stepper motor (33).

The preceding pull roll system advances at the same speed as the feed roll and maintains the film tension. If this is not done, the membrane will shift to the right or left, causing problems with the sealing of one side.

The stepper motor advances the front pull roller system while maintaining the film speed, and performs tension correction. If the tension is reduced, the current density in the motor power supply is also reduced.

The stepper motor is advanced a few degrees to correct the voltage. As the voltage increases, the current also increases and a corresponding correction is made.

The stepper motor uses a speed synchronizer on the feed roll consisting of a sprocket with an inductive sensor and a counter that counts the number of pulses per minute so that the speed of the front take-up roll is equal to the speed of the feed take-up roll.

Two constant tension wire winder with clutch (34)

The winding motor is positioned at the film outlet in front of the front film pulling roller. They rotate the winding rod where the rolls or spools of two-ply film are located. The film roll must be wound under a constant tension. As the film roll grows, the tension increases, and the clutch remains under constant tension, allowing slip and tension adjustment between the clutch plates.

The clutch-equipped motor is susceptible to overheating, so two clutch winding motors are used. When one motor works, the other motor is at rest, and the motor works continuously for 24 hours a day in one year.

An electromagnetic clutch couples the motor with the load.

When the magnetic field assembly is fixed and prevented from rotating, the rotor assembly is fixed. When the coil is energized, the armature positively connects the motor and the load. Thereby driving the load at high, medium, and low speeds.

Double-rail type continuous sealing machine

For the debugging in industry, we have to consider that the efficiency of each part is a necessary condition, which is not extended to double track machines.

The double-rail continuous film sealer uses two modules, one for blowing a balloon, dividing a tube into two rails and forming a bellows, and the other for film division.

It has a conventional module for dual rail operation. The module has an unwinder for double wide tubes, which are divided into two tubes by hot knives and sealed longitudinally, and an arched support is used to facilitate rapid cooling of the film, which is filled with air to form the bellows. In a bellows forming tower, the pull-up rolls ensure that air does not flow out of the balloon. The pull-up rolls were fitted with wooden blinds that did not allow the balloon to move out of position to form a bellows. Conventional wooden parts are used to insert the bellows.

The second or regrind module uses a cold knife to divide the sheet into two. The locations of these two modules are described below. The balloon blowing module is located at the rear of the machine and the tubular film is positioned on the rocker arm using guide rollers. The foil rewinding module is in the home position of the machine, on the upper unwinder.

The two bellows films must be centered with respect to the double track film, for which purpose two rotating guide rollers are used, mounted in such a way that they receive the bellows film and project it outwards to obtain the displacement.

The bellows-containing aluminum foil and tubular film then enter the rocker arm independently. The operation of the rocker arm is very important because the input tension of the two rails must be equal. Then, independent rocker arms, two for each track, achieve tension. The feeding roller, the chain wheel system and the electric chain are fed at two sides. Two special function devices, one for each track, then place the edge of the film sheet on the edge of the tubular film with bellows. Both of these special function devices have their sealing wheels, sealer base and film positioning rollers. The front pulling rolls maintain the film tension. The winding machine is provided with an electromagnetic clutch on each side to form two grid rolls.

Double sided printing

The film, sandwich tube and aluminum foil are now printed. Both prints have a print bar that the optical reader uses when sealing. Our machine must match these marks so that both prints are in a central position. To do this, it uses a movable roller in a four roller assembly, one of which moves in the direction of the film, increasing or decreasing the stroke, thereby positioning the indicia of the two prints, and a servo motor for adjusting the positions of the movable roller and the optical reader that positions the indicia.

Industrial process

In the extrusion sector, rolls of tubular film and plastic film with bellows are produced. The tubular film with corrugated pipe is one kind of film and its making process is blow molding extrusion, and features its film width and caliber. An air valve is arranged in the middle of the extruder die, the air ball is inflated to determine the width, and the speed of the upper pulling roll determines the caliber. The pull-up rolls bring the balloon to a flat film. With the desired width and gauge. The sheet film is manufactured in a similar manner and has an additional process in which the edges of both sides are trimmed and a single sheet is wound on a different winder. In this way we have tubular and sheet-like products in the extrusion sector.

The tubular film with bellows and foil is then printed. The next section is the printed section. The printer has one station for each color. Their ink is an input to the process. The most common solvent is an industrial type of alcohol. The inking roller places the ink for printing on its low relief screen with the unit roller. These rollers are in contact with the rollers of the western style or stamp with the printed form of each color. There is a film to be printed between the backing or bed roll and the schler roll. These stations have an interlocking system. In this way, the individually printed colors form a lake or image that is seen on the film. The drying station ensures that the print has solidified before the film spool of the printed film roll is formed.

The next part is a continuous sealer for two plastic films. In this section, the printed tubular bellows film and optionally the printed aluminum foil film are sealed longitudinally on both sides. Subsequently, the bellows of the second compartment is formed. Both ends of both films were sealed with a continuous wheel sealer. The tubular film with bellows has a base of sealant between the corrugations of the bellows. These are aluminum plates with rounded edges that protect the bellows of the original tubular film. In the sealing window, a bronze sealing wheel with a preset temperature and pressure seals the edge of the sheet against the edge of the tubular bellows. Then, the bellows of the new compartment is formed. By means of two metal frames, one being trapezoidal and the other rectangular, the enlarged compartment shape is formed, which is necessary for inserting the bellows into the new compartment. The bellows is inserted between the two metal frames by applying pressure through an external wooden fitting with rounded corners. The result is a two-compartment spool.

Alternatively, the machine for continuously sealing two plastic films has the property of producing reels of more than two lattices, each lattice having a respective bellows. The procedure for producing reels of more than two compartments is to use reels of two compartments in the lower unwinder of the machine and sheets in the upper unwinder, the manufacturing process being identical considering that the tubular sealer base and guide are between the folds of the upper bellows of the two compartments of film.

And a sealing part. The sealing portion is where the bag is made. The dual chamber bag has a reinforced handle and, because of its double bulk capacity, the load capacity (kg) is doubled as well as the conventional bag. The two compartment sandwich allows the bag to expand for optimal characteristics.

There is a current need to provide a distinctive pouch for everyone's recycling.

The technical problem is that we have no machine in the plastics industry to make such bags.

The solution to the technical problem is a continuous sealing machine for two layers of plastic film in the plastic industry, so that the industry can realize production, which threatens the durability in the industrial sector, as the industry is so important for today's lifestyle. A machine with special functions enables the plastics industry to produce packages meeting current requirements. These requirements are: firstly, we need to protect the earth; secondly, recycling is to be industrialized; thirdly, we want to protect natural resources; fourth, we have to adjust the industrial product to obtain the material recovered from the process, allowing the production of raw materials with the same molecular structure as the original raw materials.

This double-compartment bag reduces the amount of plastic used by 30% for the first use, and doubles the volume and load, taking the product home for the second use, since it can divide household waste into recyclable and non-recyclable.
