Description

Technical Field

[0001] The invention relates to the technical field of bottle making machines, in particular to a determinant-type continuous bottle making machine. Background Art

[0002] The determinant bottle making machine is a machine used for glass bottle production, which can be used in parallel in multiple groups. The high-temperature molten glass material is made into a bottle blank after passing through the primary mold, and is then fed into the bottle making machine. The bottle making machine limits the bottle blank through the molding mold, and cooperates with high-pressure inflation to make the bottle blank and the molding mold fit the shape completely, completing the shaping process. The bottle making machine then sends the shaped glass bottles to the conveyor belt to complete continuous processing.

[0003] The softening point of glass ranges from 450-550°C, and the pouring point is around 700°C. In the above process, the glass bottle after shaping is in thermal contact with the mold on the outer surface. After the mold is cooled, the temperature can be lower than the softening point after the mold is opened. However, the internal temperature of the glass bottle is still relatively high, reaching around 600°C. Especially for glass bottles with thicker walls, the temperature difference is greater. The inner wall of the glass bottle may be higher than the softening point of the glass and close to the pouring point. It needs to be cooled in time during subsequent transportation. Otherwise, deformation accumulation problems will occur under the influence of gravity and handling vibration, affecting the internal precision of the glass bottle. Summary of the Invention

[0007] The vertical clamping arm is provided with an in-bottle blowpipe, which can be telescopically movable relative to the vertical clamping arm. When the vertical clamping arm clamps and removes the bottle from the mold, the in-bottle blowpipe moves downward through the bottle mouth and is inserted into the bottle, spraying gas into the bottle to cool the inside of the bottle; the vertical clamping arm is provided with an air control seat, through which the air control seat allows the in-bottle blowpipe to gradually change the gas pressure from low to high when spraying gas.

[0008] A receiving chamber is provided in the air control seat, and a central partition tube is provided in the receiving chamber. The central partition tube is a hollow tubular structure, and a partition plate is fixedly provided inside the central partition tube.

An opening piston is provided in the regulating cavity, and the opening piston is in sealing contact with the inner wall of the regulating cavity.

[0010] The regulating chamber is provided with a regulating slot extending through the regulating chamber, and the regulating chamber is connected to the receiving chamber through the regulating slot.

[0011] A control piston is provided in the control chamber, and the control piston is in sealing contact with the inner wall of the control chamber. One end of the synchronous sealing shaft is fixedly mounted on the control piston, and the other end is fixedly mounted on the opening piston.

[0012] A variable pressure push ring is provided in the control chamber, and a return dynamic spring is provided between the variable pressure push ring and the control piston. The return dynamic spring applies elastic pressure to the control piston, and the position of the variable pressure push ring is changed, so that the elastic pressure applied by the return dynamic spring to the control piston changes.

[0013] An air hole ring is provided between the central partition tube and the inner wall of the receiving chamber. A fan blade assembly is provided on the side of the air hole ring away from the regulating slot. The gas ejected from the regulating slot is ejected onto the fan blade assembly through the air hole ring, causing the fan blade assembly to rotate.

[0014] The fan blade assembly is provided with a fan blade rotating sleeve, the fan blade rotating sleeve is provided with a permanent magnet, and an induction coil is provided outside the permanent magnet.

[0015] When the fan blade assembly rotates, the fan blade sleeve drives the permanent magnet to rotate, and the rotation speed of the permanent magnet is detected by the induction coil.

[0021] By cooperating with the air control seat, central spacer and opening piston and other structures, the jet pressure of the blowpipe in the bottle can be controlled, so that when the electromagnetic air valve is opened, the jet pressure gradually increases from low to high, avoiding the blowpipe in the bottle directly spraying air at a higher pressure, and the air pressure thrust acting on the inner wall of the bottle to cause deformation.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1 to 7 The present invention provides a technical solution: a continuous bottle making machine, such as Figure 1 As shown in the figure, it includes a molding mold 1, an air supply unit 2 and a movable rotating arm 3. The bottle blank is placed in the molding mold 1, and the bottle blank is shaped and limited by the molding mold 1. The molding mold 1 consists of two parts and can be opened and closed.

[0033] The lower end of the air supply unit 2 is connected to the molding die 1 and is used to fill the preform with pressurized gas so that the preform is in full contact with the molding die 1 for molding;

[0034] A vertical clamping arm 4 is provided on the movable rotating arm 3. The vertical clamping arm 4 remains vertically downward during the rotation of the movable rotating arm 3. When the mold 1 is opened, the molded bottle is taken out of the mold 1 by the cooperation of the movable rotating arm 3 and the vertical clamping arm 4.

[0035] An in-bottle blowpipe 5 is provided in the vertical clamping arm 4. The in-bottle blowpipe 5 can be extended and retracted relative to the vertical clamping arm 4. When the vertical clamping arm 4 clamps and takes out the bottle from the molding die 1, the in-bottle blowpipe 5 moves downward through the bottle mouth and is inserted into the bottle, spraying gas into the bottle to cool the inside of the bottle; an air control seat 6 is provided on the vertical clamping arm 4, and the air control seat 6 allows the in-bottle blowpipe 5 to gradually change its gas pressure from low to high when spraying gas.

[0036] The air control base 6 defines a receiving chamber 601, which houses a central partition 602. This hollow tubular structure houses a partition plate 603, which divides the interior of the central partition 602 into a control chamber 604 and a regulating chamber 605. A synchronous sealing shaft 606 is inserted through the partition plate 603, forming a sealed connection with the partition plate 603. The regulating chamber 605 is equipped with an opening piston 607, which forms a sealed connection with the inner wall of the regulating chamber 605.

[0037] The regulating cavity 605 is provided with a regulating slot 608 extending therethrough, and the regulating cavity 605 is connected to the receiving chamber 601 through the regulating slot 608. By moving the opening piston 607 along the axial direction of the regulating cavity 605, the blocking position of the opening piston 607 relative to the regulating slot 608 is changed, thereby adjusting the opening of the regulating slot 608. Figure 4 As shown in the figure, the regulating slot 608 is a rectangular slot structure. When the opening piston 607 moves relative to the regulating slot 608, the opening length of the regulating slot 608 will change, thereby restricting the airflow to varying degrees to achieve control of the pressure and flow of the gas ejected from the blowpipe 5 in the bottle.

[0038] A control piston 609 is provided in the control chamber 604. The control piston 609 is in sealed contact with the inner wall of the control chamber 604. One end of the synchronous sealing shaft 606 is fixedly installed with the control piston 609, and the other end is fixedly installed with the opening piston 607. A one-way air plug 610 is embedded and fixed on the control piston 609. The one-way air plug 610 allows the gas to flow in one direction from the side of the control piston 609 facing the synchronous sealing shaft 606 to the side of the control piston 609 away from the synchronous sealing shaft 606.

[0039] A variable pressure push ring 612 is provided in the control chamber 604, and a return dynamic spring 611 is provided between the variable pressure push ring 612 and the control piston 609. The return dynamic spring 611 applies elastic pressure to the control piston 609. The position of the variable pressure push ring 612 is changed, so that the elastic pressure applied by the return dynamic spring 611 to the control piston 609 changes.

[0040] An air hole ring 613 is provided between the central partition tube 602 and the inner wall of the receiving chamber 601. A fan assembly 614 is provided on the side of the air hole ring 613 away from the regulating slot 608. Gas ejected from the regulating slot 608 passes through the air hole ring 613 and is ejected onto the fan assembly 614, causing the fan assembly 614 to rotate. A fan sleeve 615 is provided on the fan assembly 614, which is equipped with a permanent magnet 616. An induction coil 617 is disposed on the exterior of the permanent magnet 616. When the fan assembly 614 rotates, the fan sleeve 615 drives the permanent magnet 616 to rotate. The induction coil 617 detects the rotational speed of the permanent magnet 616, and the position of the transformer push ring 612 is adjusted based on the change in the rotational speed of the permanent magnet 616.

[0041] A flexible air pipe 618 is provided on the outside of the receiving chamber 601, and the other end of the flexible air pipe 618 is connected to the blowpipe 5 in the bottle; a bridge cavity 619 is provided on one side of the control cavity 604, and a pipe winding frame 620 is provided in the bridge cavity 619. The pipe winding frame 620 is fixedly installed with the transformer push ring 612, and a telescopic controller 621 is fixedly provided on the vertical clamping arm 4. The telescopic controller 621 adjusts the position of the transformer push ring 612 through the pipe winding frame 620.

[0042] A beam air inlet duct 622 is provided in the air control seat 6, and an air filter plug 623 is embedded in the surface of the air control seat 6. One end of the beam air inlet duct 622 is connected to the end of the control chamber 604 close to the separating disk portion 603, and the other end of the beam air inlet duct 622 is connected to the outside atmosphere through the air filter plug 623. The beam air inlet duct 622 has a gas flow limiting function due to its diameter setting, and the air filter plug 623 is replaced regularly during use.

[0043] It also includes an electromagnetic valve 7, on which a compressed gas connecting pipe 701 and a secondary delivery pipe 702 are provided. The connection state between the compressed gas connecting pipe 701 and the secondary delivery pipe 702 is controlled by the electromagnetic valve 7, and the secondary delivery pipe 702 is connected to the end of the regulating chamber 605.

[0044] like Figure 3 and Figure 5As shown in FIG, the lower portion of the vertical clamping arm 4 is provided with a bottle mouth clamping plate 401 that can be opened and closed. The bottle mouth clamping plate 401 clamps the bottle neck and can be removed from the molding die 1. The vertical clamping arm 4 is provided with a venting groove 402 that achieves balanced air pressure inside and outside the vertical clamping arm 4.

[0045] like Figure 3 As shown in the figure, the upper end of the bottle blowing pipe 5 is fixedly provided with a blowpipe upper frame 501, and the interior of the vertical clamping arm 4 is fixedly provided with a telescopic cylinder 502. The telescopic axis of the telescopic cylinder 502 is fixedly installed with the blowpipe upper frame 501, and the bottle blowing pipe 5 is driven to move up and down by the telescopic cylinder 502.

[0046] When the bottle making machine of the present invention is in use, compressed gas connection pipe 701 is connected to a compressed gas source. After the bottle is formed in mold 1, mold 1 is opened, and the bottle making machine controls the movable rotating arm 3 and the vertical clamping arm 4 to cooperate and remove the bottle from the mold via the bottle mouth clamping plate 401. When the bottle mouth clamping plate 401 is clamped on the bottle neck, the bottle blowing pipe 5 moves downward and is inserted into the bottle, and the solenoid valve 7 is controlled to open.

[0047] like Figure 4 As shown in , after the electromagnetic valve 7 is opened, the compressed gas acts on the surface of the opening piston 607 through the secondary delivery pipe 702, pushing the opening piston 607 to move axially. As the opening piston 607 moves to the left, the opening of the control slot 608 gradually increases. During the process of the opening piston 607 moving to the left, the control piston 609 is driven to move to the left by the synchronous sealing shaft 606. At this time, the right side of the control piston 609 is in a negative pressure state, and the negative pressure inhibits the movement of the control piston 609. After being filtered by the gas filter plug 623, the external gas enters the negative pressure area on the right side of the control piston 609 through the beam inlet 622, causing the control piston 609 to move slowly to the left at a limited speed. The speed of the control piston 609 is limited, which means that the speed of the opening piston 607 is also limited, causing the opening of the control slot 608 to gradually increase. By regulating the gradual increase in the gas flow output by the slot 608, the gas passes through the receiving chamber 601, the air hole ring 613, and the flexible air tube 618 in sequence to reach the bottle blowpipe 5 and is ejected into the interior of the bottle to cool the interior of the bottle. Moreover, since the gas flow output by the slot 608 is gradually increased, the pressure of the gas ejected from the bottle blowpipe 5 gradually changes from low to high, so that the interior of the bottle is first initially cooled and solidified and then the gas pressure is gradually increased, thereby avoiding the problem of direct jetting at a higher pressure, which would cause deformation of the inner wall of the bottle in a softened state due to the gas pressure thrust.

[0048] In the above process, due to the harsh industrial production environment, when the air filter plug 623 is blocked to a certain extent and is not replaced in time, the air intake difficulty of the beam inlet 622 will increase, making the beam effect of the beam inlet 622 stronger. At this time, under the same air pressure thrust, the left movement speed of the control piston 609 is slower, resulting in a slower opening speed of the regulating slot 608, affecting the overall cooling effect.

[0049] In the present invention, the fan blade assembly 614 is provided to receive the air flow intensity blown out by the air hole ring 613, and converts it into the rotational speed of the fan blade assembly 614 and the fan blade rotating sleeve 615. Through the relative movement of the permanent magnet 616 and the induction coil 617, an induced current is generated in the induction coil 617. By monitoring the changes in the size of the induced current generated in the induction coil 617, it is possible to determine the changes in the opening of the slot 608 during a working process.

[0050] When the opening speed of the control slot 608 slows down, the position of the transformer push ring 612 is controlled by the telescopic controller 621 and the tube frame 620 to adjust the position, so that the transformer push ring 612 moves to the left, reducing the pressure on the reset dynamic spring 611, so that the rightward elastic thrust applied by the reset dynamic spring 611 to the control piston 609 is reduced. When the force of the control piston 609 moving to the left remains unchanged, the elastic force of the reset dynamic spring 611 is reduced, which can increase the negative pressure suction on the right side of the control piston 609 and increase the air intake capacity of the beam inlet 622, ensuring that the rate of movement of the control piston 609 to the left is stable, thereby making the opening change of the control slot 608 stable, which is manifested as the change curve of the jet pressure gradually increasing from low to high remaining stable.

[0051] When the bottle mouth clamp 401 releases the bottle, the blowpipe 5 in the bottle moves up and resets, and is closed by the electromagnetic air valve 7. The right side of the opening piston 607 loses the air pressure thrust. Under the elastic force of the reset dynamic spring 611, the control piston 609 and the opening piston 607 move to the right and reset. At this time, part of the gas on the right side of the control piston 609 is discharged through the beam inlet duct 622, and the other part is discharged through the one-way air plug 610.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
