Description

Three-dimensional packaging machine

technical field

The invention relates to a three-dimensional packaging machine for film packaging a fixed number of cartons.

Background technique

The three-dimensional packaging machine is used for film packaging of a fixed number of cartons. The working principle of the three-dimensional packaging machine in the prior art is: the fixed number of cartons are stacked horizontally in a row and pushed into the packaging forming channel in the packaging machine by the pushing parts. When the box is pushed, the film blocking the front of the carton is cut to a fixed length and wraps the carton. At the same time, the film forms left and right hems under the action of the left and right hemming parts, and then the bottom sealing part seals the film packaging. , and then, the pushing part pushes the rear row of cartons and pushes the front row of cartons forward through the rear row of cartons, so the film packaging of the front row of cartons forms the upper and lower hems under the action of the upper and lower hemming parts , at the last station, the upper and lower folds are side-sealed under the action of the side-sealing part, and under the action of the pushing part again, the front row of cartons that complete the three-dimensional packaging are pushed out of the packaging machine, according to This cycle carries out the three-dimensional packaging production of cartons.

The three-dimensional packaging machine of the prior art mainly has the following deficiencies: 1. In the three-dimensional packaging machine of the prior art, the forward action of the front row of cartons in the film packaging process is promoted by the rear row of cartons, so After the equipment is shut down, there will always be many rows of cartons still left in the packaging machine because there are no rear cartons to push them, so the packaging machine has the problem of stopping and storing materials. The cartons left in the packaging machine need to be taken out manually, which is troublesome to operate. The degree of automation is not high; in addition, since the forward movement of the front row of cartons during the film packaging process is driven by the rear row of cartons, the front and rear rows of cartons are close to each other, so that the packaging When the side sealing part of the machine performs side sealing on the film packaging of the front row of cartons, the film packaging of the front row of cartons and the film packaging of the rear row of cartons are prone to adhesion, so the packaging machine has side sealing The sticking problem not only affects the packaging quality, but also affects the production speed. 2. The three-dimensional packaging machine in the prior art generally performs the film unwinding action with a single unwinding reel, because it cannot realize the fast splicing action, so it cannot meet the high-speed production requirements of the three-dimensional packaging machine. In addition, the reel unwinds the film. The tension of the film is not easy to control stably when unwinding, so the packaging quality cannot be well guaranteed. 3. In the existing three-dimensional packaging machine, the cut-to-length film is unwound on the film unwinding shaft, but when a roll of film is used up and needs to be docked with a new film, it cannot be spliced quickly. Therefore, it cannot meet the high-speed production requirements of three-dimensional packaging machines. 4. In the existing three-dimensional packaging machine, the fixed-length cutting of the film is completed by the rolling cutting action of the upper and lower hobs. The cutting length of the film is not easy to control and adjust, the working noise is large, and the tool life is short, which cannot meet the requirements of the three-dimensional packaging machine. high-speed production requirements. 5. In the three-dimensional packaging machine of the prior art, the pushing head of the pushing part must push the front row of cartons forward in the first half of the pushing action, and return according to the original path in the second half of the pushing action. During the entire pushing action time of the material head, the rear row of cartons cannot be filled in place, so the pushing time is longer, which cannot better meet the high-speed production requirements of the three-dimensional packaging machine. 6. In the three-dimensional packaging machine of the prior art, the bottom sealing head of the bottom sealing part only moves up and down, and because the film is generally in a loose state before the bottom sealing of the film packaging, the bottom sealing The thin film packaging is often not tight, and the film at the bottom sealing part is also easy to wrinkle, which affects the packaging quality, and also limits the further improvement of the production speed of the three-dimensional packaging machine.

Contents of the invention

In view of the deficiencies of the existing technology, the technical problem to be solved by the present invention is to provide a three-dimensional packaging machine with good packaging quality and high production speed, and solve the problem of stopping and stocking in the prior art.

The present invention is accomplished by taking the following technical solutions:

The three-dimensional packaging machine is characterized in that: the film sent by the film feeding part passes through the floating guide roller and then is sent downward at a fixed length by the traction guide roller. There is a box feeding platform under the film part, and a pushing part is arranged on the rear side of the box feeding platform. The pushing part pushes the rows of cartons on the box feeding platform into the packaging forming channel.

After adopting the above technical solution, the three-dimensional packaging machine has added the setting of traction parts, so that the forward movement of the front row of cartons in the process of film packaging is not pushed by the back row of cartons but by the traction parts. Carry out traction and push, so just at first just solved the problem that the existing three-dimensional packaging machine of the prior art stops to store material, can make the front and rear rows of cartons be separated from each other by a certain distance, so that the side sealing parts of the packaging machine are facing the front row of paper. When the film packaging of the carton is side-sealed, the film packaging of the front row of cartons will not stick to the film packaging of the rear row of cartons, which solves the problem of side sealing adhesion in the prior art three-dimensional packaging machine . Since the problem of material storage at shutdown and side seal adhesion is solved, the packaging quality and production speed of the three-dimensional packaging machine can be effectively improved. The traction action process of the traction part is: at the initial position, the traction cylinder first pushes the second movable seat to move upward, and then drives the first movable seat and the traction platform to move upward through the first horizontal sliding assembly, so that the carton is positioned at the traction claw block. Then the servo motor works in the forward direction, the synchronous belt drives the horizontal push block to move forward, and the horizontal push block drives the first movable seat and the traction platform to move forward through the first vertical sliding assembly, so the carton is pushed forward After the carton reaches the designated position, the traction cylinder pushes the second movable seat to move downward, and then drives the first movable seat and the traction platform to move downward through the first horizontal sliding assembly, so that the carton is separated from the space surrounded by the traction claw block Then the traction motor works in reverse, the traction synchronous belt drives the horizontal push block back, and the horizontal push block drives the first movable seat and the traction platform to move backward through the first vertical sliding assembly, so the traction platform returns to the initial position and waits The next push action.

On the top of the friction wheel, the friction block is connected to the swing rod. One end of the swing rod is hingedly connected with the film feeding bracket, and the other end is connected with the tension spring of the swing rod. Under the action of the swing rod tension spring, the friction block and the friction wheel are closely attached to each other. Contact, the side of the swing rod extension spring is provided with a swing rod cylinder, the push rod of the swing rod cylinder is facing the swing rod, and when the swing rod cylinder moves, it promotes the swing rod to swing upwards, and the friction block breaks away from the contact with the friction wheel.

After adopting the above technical scheme, the film feeding part controls the feeding by floating the floating guide roller up and down. When the film is pulled by the leading guide roller and the floating guide roller reaches the upper limit position, the upper probe switch sends a signal to control the air intake of the pendulum rod cylinder. The action of the pendulum rod cylinder moves the pendulum rod to swing upwards, so the friction block breaks away from the contact with the friction wheel, and the corresponding unwinding shaft is released. At this time, under the gravity of the floating guide roller, the unwinding shaft starts to unwind the film, while floating The guide roller moves downward. When the floating guide roller reaches the lower limit position, the lower probe switch sends a signal to control the swing rod cylinder to stop the air intake. The swing rod swings downward under the action of the swing rod tension spring, so the friction block and the friction wheel are attached Close contact, the corresponding unwinding shaft is locked, at this time the floating guide roller stays at the lower limit position, as the film is pulled again, the floating guide roller starts to move upwards to the upper limit position, and so on. During the above action process, you can Realize high-quality film feeding action, long-term stable control of film tension, convenient control, and ensure packaging quality. At the same time, due to the double unwinding reel design, it can help realize fast film change and meet the high-speed production requirements of three-dimensional packaging machines.

As preferably, the film sent out by the film-feeding part enters the floating guide roller after passing through the film-bonding part.

After adopting the above-mentioned technical scheme, the film splicing action can be realized quickly. The action process is: at the beginning, if the lower film roll material provides the film material for film packaging for the three-dimensional packaging machine, then when the lower film roll material is about to be used up, the upper film roll material The upper film is pre-introduced into the upper film introduction channel through the upper guide roller group until it passes the position of the upper and lower heat-sealing ironing heads, and then press the upper film bonding action switch, so the upper heat-sealing cylinder pushes the upper heat-sealing iron head to move down and heat it down The sealing cylinder pushes the lower heat-sealing head to move up, and the upper and lower heat-sealing heads are closed to heat-seal the upper and lower films. At the same time, the lower film cutting cylinder pushes the lower film cutting iron head to move up to cut the lower film. The next step is the upper film roll. The material provides the film material for film packaging for the three-dimensional packaging machine, so as to realize the fast splicing action; similarly, if the upper film roll material provides the film material for film packaging for the three-dimensional packaging machine at the beginning, then when the upper film roll material is about to run out , the lower film of the lower film roll material is introduced into the lower film introduction channel in advance through the lower guide roller group until it passes the position of the upper and lower heat-sealing ironing heads, and then presses the action switch of the lower film joining film, so the upper heat-sealing cylinder pushes the upper heat-sealing ironing head Moving down and down the heat-sealing cylinder pushes the lower heat-sealing head to move up, the upper and lower heat-sealing heads are closed to heat-seal the upper and lower films, and at the same time the upper film cutting cylinder pushes the upper film cutting head to move down to cut the upper film, then The next thing is to provide the film material for film packaging to the three-dimensional packaging machine, so as to realize the fast splicing action. Because it can realize fast film splicing action, it can meet the high-speed production requirements of three-dimensional packaging machines.

As preferably, the film cutting part includes a fixedly installed film cutting front plate and a film cutting rear seat, and a film passing gap is left between the film cutting front plate and the film cutting rear seat to allow the film to pass freely from top to bottom.

The cutter cylinder is fixedly installed on the film cutting back seat, and the cutting blade moves forward. Finally, it is reset by the cutter spring, and the cutting blade is clamped by the upper and lower pressure plates. The front end of the upper and lower pressure plates is equipped with rubber pressure strips, and the upper and lower pressure plates are fixedly connected by sliders. It is located in the back seat of the cutting film. The forward movement of the slider is pushed by the cutter spring. The front end of the cutter spring is against the slider, and the rear end of the cutter spring is against the cutting blade. Block spring resets.

After adopting the above technical scheme, the film cutting action can be realized quickly. The action process is: the cutter cylinder moves to push the cutting blade forward, and the cutting blade pushes the slider and the upper and lower pressure plates forward through the cutter spring, and the slider compresses the slider spring until it goes up and down. The rubber bead on the front end of the pressing plate presses the film tightly on the front plate of the cutting film. As the cutting blade continues to move forward, the cutting blade compresses the spring of the cutting knife and passes forward from the middle of the upper and lower pressing plates to cut the compressed film. When the film is cut off, the cutter cylinder returns quickly, so the cutter blade returns quickly under the joint action of the cutter spring and the slider spring, waiting for the next film cutting action. Due to the fast film cutting action, it can meet the high-speed production requirements of the three-dimensional packaging machine, and because the cutting blade is only in contact with the film during the film cutting action, so the wear is small and the service life is long.

As preferably, the pushing part comprises a pushing head and a pushing bracket, and the pushing bracket is fixedly installed, and the pushing head is connected to one end of the pushing rod, and the other end of the pushing rod is connected to a vertical rail, and the vertical rail can be moved up and down.

The front end of the swing guide rail has an inclined guide rail surface, and rollers are installed on the top of the vertical guide rail. When the rollers are located above the swing guide rail, the rollers roll along the swing guide rail.

After adopting the above technical scheme, the pushing head does not return according to the original path in the second half of the pushing action, but first lifts up and then returns, because the upward lifting action stroke is small and short, so the pushing time of the pushing head Most of the time in the second half of the operation, the rear cartons can be filled in place, that is, the entire pushing time is short, so as to realize fast pushing action and better meet the high-speed production requirements of the three-dimensional packaging machine. Its working principle is: in the first half of the pushing action, the pushing motor works forward through the pushing timing belt, sliding seat, vertical guide rail and pushing rod to drive the pushing head forward to carry out the pushing action. At this time, the swing cylinder pushes The swing guide rail swings upwards to allow the space for the rollers to pass. In the second half of the push action, the push motor works in reverse through the push timing belt, sliding seat, vertical guide rail and push rod to drive the push head back. At this time, the swing The guide rail is in the downward swing position under the action of the guide rail tension spring, so the rollers roll along the swing guide rail, and then drive the push head to rise rapidly through the vertical guide rail and the push rod. Make room for the rear tray to fill in place.

Preferably, a buffer frame is fixed on the sliding seat, a buffer member is installed on the buffer frame, and a stopper is fixedly arranged on the vertical guide rail. Through the above design, in the first half of the pushing action, the pushing head can be kept at a certain height, and the horizontal pushing action can be better; and at the end of the second half of the pushing action, when the roller leaves the contact with the swing guide rail , it can prevent the collision between the stopper and the sliding seat.

As a preference, the box-entry platform is provided with a box-stopping plate, and the box-stopping plate is movable and pushed by a box-stopping cylinder, which is fixedly installed on a box-stopping support, and the box-stopping support is adjustable on the box-entrying platform. Through the above design, the box stopper is usually used for the stacking and positioning of the cartons fed into the box feeding platform. The material head is faster and better to push the carton forward to ensure the carton is neat.

As preferably, the bottom seal part includes a bottom seal ironing head and a bottom seal seat, the bottom seal seat is fixedly installed, the bottom seal ironing head is fixedly connected to the top of the swing plate, and the swing plate swings on the lifting slide table, and the swing of the swing plate is controlled by the swing plate. The plate cylinder is used to push, and the up and down movement of the lifting slide is set on the bottom seal seat, and the up and down movement of the lifting slide is driven by the bottom seal cylinder.

After adopting the above technical scheme, the film packaging of the carton can be made more compact, the packaging quality can be improved, and the high-speed production requirements of the three-dimensional packaging machine can be better met. The action of the sealing cylinder pushes the lifting slide table and drives the bottom sealing head to move upwards. After the bottom sealing head reaches the working position, the swing plate cylinder pushes the bottom sealing head to swing forward. The film of the film packaging is properly tensioned, and finally the tensioned film is bottom-sealed, so that the film packaging of the carton is more compact, and the film at the bottom sealing part is not easy to wrinkle, which improves the packaging quality .
