Description

Technical Field

[0001] This invention relates to the technical field of sealing machines. More specifically, this invention relates to a sealing machine based on intelligent control. Background Technology

[0002] In the processing of aluminum foil balloons, the plastic film nozzle must first be accurately placed at the pre-set opening between two aluminum foil composite films. Then, a sealing machine presses the two aluminum foil composite films together around their perimeter to form a closed heat-sealing line, completing the perimeter sealing of the film. Simultaneously, the film nozzle is heat-sealed and fixed between the upper and lower aluminum foil composite films at the pre-set opening, achieving a complete seal. However, in this sealing area, the upper aluminum foil composite film, the upper wall of the nozzle, the lower wall of the nozzle, and the lower aluminum foil composite film will be stacked sequentially, forming a four-layer film structure. During sealing, if the heat-sealing temperature is too high, the pressure is too great, or the pressure holding time is too long, these four layers of film are easily heat-pressed together, especially causing the two layers of film inside the nozzle to fuse and block each other, closing the nozzle channel and severely affecting subsequent inflation operations. Summary of the Invention

[0003] In order to overcome the drawback of existing sealing machines where the air nozzle is easily clogged when it is fixed on the aluminum foil composite film, this invention provides a sealing machine based on intelligent control.

[0004] The technical solution of this invention is: a sealing machine based on intelligent control, comprising connecting plates and telescopic cylinders; several connecting plates are provided; several telescopic cylinders are fixedly connected to each connecting plate; it also includes a sealing device, a heating head, an electric push rod, a connecting block, and a limiting block; a sealing device is provided on the side of each connecting plate, and the sealing device is fixedly connected to the telescopic end of the corresponding telescopic cylinder; a heating head is installed on each sealing device; a groove is provided on each heating head; an electric push rod is provided on the side of the connecting plate; a connecting block is fixedly connected to the telescopic end of the electric push rod; a limiting block is fixedly connected to the connecting block.

[0005] Furthermore, a displacement sensor is installed on the connecting block.

[0006] By employing the above-described structure, this invention achieves displacement monitoring.

[0007] Furthermore, the limiting block has several chamfered portions.

[0008] By adopting the above structure, the present invention achieves a convenient insertion effect.

[0009] Furthermore, it also includes limit block two; several limit blocks two are fixedly connected to limit block one.

[0010] Furthermore, it also includes a telescopic component, which includes pipe one, pipe two, and protrusions; the limiting block one consists of a fixed part, a movable part one, and a movable part two; the fixed part is fixedly connected to the connecting block; the movable part one is slidably connected to the fixed part; the movable part two is slidably connected to the fixed part; pipe one is fixedly connected to the fixed part; several pipes two are fixedly connected to pipe one, and pipes two communicate with pipe one; a cavity is formed between the fixed part and the movable part one; a cavity is also formed between the fixed part and the movable part two; the cavity communicates with the corresponding pipe two; several protrusions are fixedly connected to the movable part one; several protrusions are also fixedly connected to the movable part two; the protrusions are slidably connected to the fixed part.

[0011] Furthermore, it also includes a pipe three; a pipe three is fixedly connected to the movable part one, and the pipe three is connected to the movable part one; a pipe three is also fixedly connected to and connected to the movable part two; a number of through holes one are opened on the movable part one; a number of through holes one are also opened on the movable part two; a number of through holes two are opened on the fixed part.

[0012] Furthermore, the surface of the limiting block is set to a smooth surface.

[0013] Furthermore, a sealing ring is provided between the fixed part and the first movable part; a sealing ring is provided between the fixed part and the second movable part.

[0014] By adopting the above structure, the present invention achieves a stronger sealing effect.

[0015] Furthermore, a temperature sensor is installed on the sealer.

[0016] Furthermore, an alarm is installed on the sealing device.

[0017] The beneficial effects are: First, by separating the upper and lower walls of the film nozzle by the limiting block, the problem of the upper and lower walls of the film nozzle sticking together is effectively prevented, thus preventing blockage that may affect subsequent inflation operations. At the same time, during hot pressing, the limiting block limits the film nozzle, effectively preventing the film nozzle from shifting, thus ensuring the aesthetics and consistency of the aluminum foil balloon product. No other fixing structure is required, making the structure more streamlined. Second, by dividing the limiting block into a fixed part, a movable part one, and a movable part two, during the insertion of the membrane nozzle and the removal of the limiting block, the movable part one and the movable part two are controlled by gas to be drawn into the middle of the fixed part, thereby reducing the volume of the limiting block one. This avoids the problem of wrinkling and stacking when the membrane nozzle is inserted, and significantly reduces the frictional force generated by the limiting block one on the membrane nozzle when it is removed. This reduces the impact on the welding structure of the composite membrane one, the membrane nozzle, and the membrane nozzle of the composite membrane two, which is beneficial to improving structural stability. Third, by supplying air through pipe three, the membrane nozzle bulges up and stops adhering to the limiting block one. When the limiting block one is pulled out from the inside of the membrane nozzle, the frictional force generated by the limiting block one on the membrane nozzle can be further reduced, thereby reducing the impact on the welding structure of composite membrane one, membrane nozzle, and composite membrane two, which is conducive to improving structural stability.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] Example 1: A sealing machine based on intelligent control, such as... Figures 1-9 ,include: Multiple connecting plates 1, each connecting plate 1 having multiple telescopic cylinders 2 fixed on it; Also includes: Multiple sealing devices 3 are respectively installed on the side of each connecting plate 1, and each sealing device 3 is fixedly connected to the telescopic end of the corresponding telescopic cylinder 2. Multiple heating heads 4, each heating head 4 is mounted on a sealing device 3, and each heating head 4 has a groove 491; An electric push rod 5 is located on the side of the connecting plate 1, and a connecting block 6 is fixedly connected to the telescopic end of the electric push rod 5. Limiting block 7 is fixedly connected to the connecting block 6.

[0022] A displacement sensor is provided on the connecting block 6 to monitor the movement distance of the connecting block 6, thereby enabling the connecting block 6 to drive the limiting block 7 and the diaphragm nozzle 10 to move to the designated position.

[0023] The limiting block 7 has two chamfered portions 492, which makes it easier to fit the diaphragm nozzle 10 onto the outside of the limiting block 7.

[0024] It also includes limit block 201; two limit blocks 201 are welded on limit block 1 7.

[0025] First, both ends of composite film 8 and composite film 9 are located in the external winding and unwinding machine. During edge sealing and end sealing, the film nozzle 10 is manually placed outside the limiting block 7 until the end of the film nozzle 10 abuts against the limiting block 201, thereby positioning the film nozzle 10 through the limiting block 201. Then, the electric push rod 5 drives the connecting block 6 to move backward, the connecting block 6 drives the limiting block 7 to move backward, and the limiting block 7 drives the film nozzle 10 to move backward, so that the middle and rear part of the film nozzle 10 moves into the gap between composite film 8 and composite film 9. At this time, the positional relationship between composite film 8, composite film 9 and film nozzle 10 is as follows. Figure 6As shown, the limiting block 7 is aligned with the groove 491. Then, the telescopic cylinder 2 drives the sealing device 3 to move, and the sealing device 3 drives the heating head 4 to move, so that the two heating heads 4 move towards each other and clamp the composite film 8, composite film 9, film nozzle 10 and limiting block 7. At this time, the groove 491 moves to the outside of the limiting block 7, so that the upper wall of the film nozzle 10 contacts the composite film 8 and the lower wall of the film nozzle 10 contacts the composite film 9. The upper wall and the lower wall of the film nozzle 10 do not contact each other. The heating head 4 heats the composite film 8 and composite film 9, so that the thermoplastic layer of the composite film 8 and composite film 9 melts. The thermoplastic layer of the composite film 8 and composite film 9 is set in the opposite position, so the composite film 8 and composite film 9... 9. The molten thermoplastic layers in contact adhere together, completing the edge sealing operation. Simultaneously, the limiting block 7 provides support, causing the heating head 4 to press the composite film 8 against the upper wall of the film nozzle 10 and the heating head 4 to press the composite film 9 against the lower wall of the film nozzle 10. This results in the upper wall of the film nozzle 10 adhering to the molten thermoplastic layer of the composite film 8 and the lower wall of the film nozzle 10 adhering to the molten thermoplastic layer of the composite film 9, completing the sealing operation. During this process, the limiting block 7 separates the upper and lower walls of the film nozzle 10. The limiting block 7 itself is made of non-stick material, effectively preventing the upper and lower walls of the film nozzle 10 from adhering together, thus preventing blockages that could affect subsequent inflation operations.

[0026] If the film nozzle 10 is directly inserted into the target position in the gap between composite film 8 and composite film 9 for hot pressing, the airflow generated by the closure of composite film 8 and composite film 9 will cause the film nozzle 10 to move, resulting in displacement of the film nozzle 10. This will affect the aesthetics and consistency of the aluminum foil balloon. Therefore, existing technologies usually use additional fixing structures to press the film nozzle 10 tightly to prevent displacement, which is complex. However, when the film nozzle 10 is inserted into the target position in the gap between composite film 8 and composite film 9 for hot pressing, the film nozzle 10 can be limited by the limiting block 7, effectively avoiding the displacement problem of the film nozzle 10. This ensures the aesthetics and consistency of the aluminum foil balloon, and eliminates the need for other fixing structures, making the structure more streamlined.

[0027] During use, the upper and lower walls of the film nozzle 10 are separated by the limiting block 7, effectively preventing them from sticking together and thus preventing blockages that could affect subsequent inflation operations. At the same time, during hot pressing, the limiting block 7 limits the film nozzle 10, effectively preventing it from shifting, thus ensuring the aesthetics and consistency of the aluminum foil balloon. No other fixing structures are required, making the structure more streamlined.

[0028] It also includes a telescopic assembly, which includes a first pipe 202, a second pipe 203, and a protrusion 204; the first limiting block 7 is composed of a fixed part 791, a first movable part 792, and a second movable part 793; the fixed part 791 is bolted to the connecting block 6; the first movable part 792 is slidably connected to the fixed part 791; the second movable part 793 is slidably connected to the fixed part 791; the first pipe 202 is fixedly connected to the first pipe 202; two second pipes 203 are connected and fixedly connected to the first pipe 202; a cavity 794 is formed between the fixed part 791 and the first movable part 792; a cavity 794 is also formed between the fixed part 791 and the second movable part 793; the cavity 794 is connected to the corresponding second pipe 203; two protrusions 204 are welded to the first movable part 792; two protrusions 204 are also welded to the second movable part 793; the protrusions 204 are slidably connected to the fixed part 791.

[0029] To avoid wrinkles during hot pressing, the film nozzle 10 should fit tightly against the limiting block 7. This results in relatively large frictional resistance between the film nozzle 10 and the limiting block 7 when the film nozzle 10 is fitted onto the outside of the limiting block 7 and when the limiting block 7 is pulled out of the hot-pressed film nozzle 10. This affects the fitting and pulling operations (when fitting: the film nozzle 10 is easily wrinkled and stacked under the pushing force, affecting the sealing operation; when pulling out: the limiting block 7 applies frictional force to the film nozzle 10, and the frictional force acts on the composite film 8 and composite film 9 through the film nozzle 10, while the composite film 8 and film nozzle 10 and composite film 9 are just fused together). (Since the welded structure is not fully cured, which may affect the welded structure, during preparation, an external air pump is connected to pipe 202. The diaphragm nozzle 10 is then placed outside the limiting block 7. The external air pump evacuates pipe 202, causing air in cavity 794 to flow into pipe 202 through pipe 203 and then out through pipe 202, creating a negative pressure state inside cavity 794. This atmospheric pressure then pushes movable parts 792 and 793 towards the center of fixed part 791, reducing the volume of limiting block 7. At this point, the diaphragm nozzle 10 can be easily placed manually.) Located outside the limiting block 7, the membrane nozzle 10 will not wrinkle or stack. An external air pump supplies gas to pipe 202, which flows into cavity 794 through pipes 202 and 203, pressurizing the cavity. This pressurizes movable parts 792 and 793, moving them away from the center of fixed part 791. Movable parts 792 and 793 then move their corresponding protrusions 204 to their extreme positions, returning them to their original positions. The fixed part 791, movable parts 792 and 793 together expand the membrane nozzle 10, ensuring it fits tightly against the limiting block 7. Subsequently, the limiting block 7 drives the film nozzle 10 to move into the gap between the composite film 8 and the composite film 9 for sealing. After sealing, the above operation is repeated, causing the movable part 792 and the movable part 793 to move towards the center of the fixed part 791, reducing the volume of the limiting block 7. Then, the electric push rod 5 drives the connecting block 6 to move forward, and the connecting block 6 drives the limiting block 7 to move forward, pulling the limiting block 7 out from the inside of the film nozzle 10. This significantly reduces the frictional force generated by the limiting block 7 on the film nozzle 10 during this process, thereby reducing the impact on the welding structure of the composite film 8, the film nozzle 10, and the composite film 9, which is beneficial to improving structural stability.In use, by dividing the limiting block 7 into a fixed part 791, a movable part 792, and a movable part 793, during the insertion of the membrane nozzle 10 and the removal of the limiting block 7, the movable parts 792 and 793 are controlled by gas to retract into the middle of the fixed part 791, reducing the volume of the limiting block 7. This avoids the problem of wrinkling and stacking when the membrane nozzle 10 is inserted, and significantly reduces the frictional force generated by the limiting block 7 on the membrane nozzle 10 when it is removed. This reduces the impact on the welding structure of the composite membrane 8, the membrane nozzle 10, and the composite membrane 9, thus improving structural stability.

[0030] It also includes pipe 3 205; pipe 3 205 is connected and fixed to movable part 1 792; pipe 3 205 is also fixed and connected to movable part 2 793; four through holes 1 795 are opened on movable part 1 792; four through holes 1 795 are also opened on movable part 2 793; eight through holes 2 796 are opened on fixed part 791.

[0031] The surface of the limiting block 7 is set to a smooth surface, which helps to reduce friction.

[0032] First, the external air pump is manually connected to pipe 205. After sealing, the movable parts 792 and 793 are moved towards the center of the fixed part 791. At this time, the through hole 795 and the through hole 796 are aligned. Then, air is supplied to pipe 205 through the external air pump. The air flows into the inside of the movable parts 792 and 793 through pipe 205 and then sprays out from the through holes 795 and 796. The gas impacts the membrane nozzle 10, causing the membrane nozzle 10 to bulge and stop adhering to the limiting block 7. At this time, the limiting block 7 is immediately removed from the membrane nozzle 1 by the electric push rod 5. Pulling the limit block 7 out from the inside further reduces the frictional force between the limit block 7 and the diaphragm nozzle 10, thus minimizing the impact on the welding structure of the composite membrane 8, the diaphragm nozzle 10, and the composite membrane 9. During use, air is supplied through pipe 3 205 to cause the diaphragm nozzle 10 to bulge and stop adhering to the limit block 7. Pulling the limit block 7 out from the inside of the diaphragm nozzle 10 further reduces the frictional force between the limit block 7 and the diaphragm nozzle 10, minimizing the impact on the welding structure of the composite membrane 8, the diaphragm nozzle 10, and the composite membrane 9, thus improving structural stability.

[0033] In Example 2, based on Example 1, a sealing ring is provided between the fixed part 791 and the movable part 792 to improve the sealing performance; a sealing ring is also provided between the fixed part 791 and the movable part 793 to improve the sealing performance.

[0034] A temperature sensor is installed on the sealer 3 to monitor the temperature of the heating head 4.

[0035] The sealing device 3 is equipped with an alarm. When the temperature of the heating head 4 is abnormal, the alarm will sound to remind the staff to go for maintenance.
