Description

Technical Field

[0001] This invention relates to the field of lapel packaging machine technology, specifically a continuous lapel packaging machine. Background Technology

[0002] The collar packaging machine is a fully automatic vertical packaging equipment. Its core is to use a collar forming device to fold a roll of flat film into a cylindrical shape, and continuously complete bag making, metering, filling, sealing and cutting. It is commonly used for small and medium-sized bag packaging of granules, powders, liquids, snacks and other products.

[0003] As in the prior art, Chinese Patent Publication No. CN220164241U discloses a collar packaging machine, including a cabinet, a film feeding mechanism, a filling mechanism, a collar forming mechanism, a longitudinal sealing mechanism, a transverse sealing and cutting mechanism, and a traction mechanism. The cabinet has an installation side, and the film feeding mechanism, the filling mechanism, the collar forming mechanism, the longitudinal sealing mechanism, and the traction mechanism are respectively installed on the installation side. The transverse sealing and cutting mechanism is installed on the traction mechanism, and the film feeding mechanism, the filling mechanism, the collar forming mechanism, the longitudinal sealing mechanism, the transverse sealing and cutting mechanism, and the traction mechanism are distributed sequentially along the direction of film movement.

[0004] As in the prior art, Chinese Patent No. CN223494899U discloses a lapel-type back-seal packaging machine with flow rate adjustment, including a frame, a hopper and a feeding mechanism installed on the frame, a feeding valve provided between the hopper and the feeding mechanism, the feeding mechanism including an upper shell and a baffle plate, the bottom of the upper shell communicating with the lower shell through an opening, the baffle plate being rotatably installed inside the upper shell through a drive shaft, an arc-shaped feeding wall provided on one inner wall of the upper shell, the side of the baffle plate near the arc-shaped feeding wall being circular, and a gap for material to pass through between the baffle plate and the arc-shaped feeding wall.

[0005] For example, in the prior art, Chinese patent publication number CN211593039U discloses a collar forming bag making and packaging machine that can quickly weigh and automatically collect waste products. It includes a frame, a material conveying mechanism, a mixing hopper, a collar forming device, a longitudinal sealing device, and a transverse sealing and cutting mechanism, all of which are installed on the frame. The frame is also equipped with a finished product distribution mechanism, multiple weighing and pushing bag mechanisms, multiple screening mechanisms, and a waste collection frame.

[0006] Based on the above information, it can be seen that in the prior art, the heat sealing mechanism and the film feeding mechanism of the packaging machine work independently. That is, the film feeding mechanism stops working during heat sealing and is restarted after heat sealing is completed to feed the film. This process involves a waiting period, which reduces the overall working efficiency of the device. Summary of the Invention

[0007] The purpose of this invention is to provide a continuous lapel packaging machine to solve the problem of low working efficiency mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a continuous lapel packaging machine, comprising a support frame with a frame structure, a feeding component disposed above the support frame, and a film feeding component disposed behind the support frame, an installation frame fixedly installed inside the support frame, a horizontal sealing component being connected through the installation frame, and a vertical sealing component corresponding to the horizontal sealing component being disposed inside the support frame, a conveying component being disposed behind the vertical sealing component, a first lifting mechanism being disposed on the back of the installation frame, the horizontal sealing component moving synchronously with the packaging film via the first lifting mechanism, a second lifting mechanism being disposed inside the support frame, the vertical sealing component moving synchronously with the packaging film via the second lifting mechanism, the horizontal sealing component and the vertical sealing component being moved up and down respectively by the screw structure inside the first lifting mechanism and the second lifting mechanism, maintaining film feeding operation during heat sealing, a feeding pipe corresponding to the feeding component being fixedly installed inside the support frame, and a guide plate being fixedly installed outside the feeding pipe.

[0009] Preferably, the horizontal sealing assembly includes a main movable frame and a secondary movable frame. A front heating block is installed on the inner side of the front end of the main movable frame, and a rear heating block is installed on the front side of the secondary movable frame. The secondary movable frame and the main movable frame are connected through a sliding connection.

[0010] Preferably, a drive rod driven by a control motor is provided between the main movable frame and the auxiliary movable frame. Connecting rods are rotatably installed at both ends of the drive rod, and the two connecting rods rotatably connect the main movable frame and the auxiliary movable frame respectively. The drive rod is driven to rotate by the control motor. During the rotation of the drive rod, the main movable frame and the auxiliary movable frame are pulled to move through the connecting rods connected to it, so that the front heating block and the rear heating block installed on the main movable frame and the auxiliary movable frame move closer to each other.

[0011] Preferably, the first lifting mechanism includes a fixed frame located outside the main movable frame, and the main movable frame and the fixed frame are slidably connected through each other.

[0012] Preferably, the fixing frame is slidably connected to the guide rail fixedly installed on the back of the mounting frame, and a first lead screw driven by a first servo motor is rotatably installed on the back of the mounting frame, so that the fixing frame can move up and down relative to the mounting frame through the rotation of the first lead screw.

[0013] Preferably, the front heating block is connected to the main movable frame via a pad, and the rear heating block is connected to the auxiliary movable frame via a pad. Both the front and rear heating blocks have air outlets inside. The pad has a through hole corresponding to the air outlet on its side. A piston block is slidably installed inside the pad. A return spring is fixedly installed between the piston block and the inner wall of the pad. The piston block moves relative to the pad and squeezes out air. During heat sealing, the pressure of the front and rear heating blocks coming close together is applied to the pad, causing the pad and piston block to slide relative to each other. At this time, the piston block squeezes the air inside the pad. The squeezed air enters the air outlet through the through hole and is ejected. The ejected airflow cools the heat-sealed position in time.

[0014] Preferably, the longitudinal sealing assembly includes a connecting arm, a fixed heating block, and a movable heating block. The fixed heating block is fixedly connected to the connecting arm, and the movable heating block forms a sliding structure with the connecting arm via a cylinder.

[0015] Preferably, the second lifting mechanism includes a connecting frame fixedly installed inside the support frame, and a second lead screw driven by a second servo motor is rotatably installed inside the connecting frame. The connecting arm moves up and down relative to the connecting frame through the rotation of the second lead screw.

[0016] Preferably, the conveying assembly includes a mounting plate on which a conveyor belt is installed, and a pneumatic telescopic rod is installed between the mounting plate and the support frame. The pneumatic telescopic rod is used to push the mounting plate to move, so that the conveyor belt connected to the mounting plate is in close contact with the packaging bag film. The friction between the conveyor belt and the packaging bag film is used to achieve the purpose of traction and conveying the packaging bag film.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This continuous lapel packaging machine adopts a novel structural design, the specific details of which are as follows: 1. The horizontal sealing assembly and the vertical sealing assembly are driven to move up and down by the screw structure inside the first lifting mechanism and the second lifting mechanism respectively. Before heat sealing, the horizontal sealing assembly and the vertical sealing assembly move upward. When heat sealing, the horizontal sealing assembly and the vertical sealing assembly move downward synchronously with the packaging film, thereby maintaining the film feeding operation during the heat sealing process, reducing or even eliminating the waiting interval, and improving the overall working efficiency of the device. Furthermore, by controlling the motor to drive the drive rod to rotate, the drive rod pulls the main movable frame and the auxiliary movable frame to move through the connecting rod connected to it, so that the front heating block and the rear heating block installed on the main movable frame and the auxiliary movable frame move closer to each other, so as to achieve the purpose of heat sealing the top and bottom ends of the packaging bag.

[0018] 2. The mounting plate is moved by a pneumatic telescopic rod, so that the conveyor belt connected to the mounting plate is in close contact with the packaging bag film. Then, the motor on the outside of the mounting plate drives the conveyor belt to rotate, and the friction between the conveyor belt and the packaging bag film is used to achieve the purpose of traction and conveying the packaging bag film.

[0019] 3. Pads are placed between the front heating block and the main movable frame, and between the rear heating block and the auxiliary movable frame. During heat sealing, the pressure of the front heating block and the rear heating block coming close together is applied to the pads, causing the pads and the piston block to slide relative to each other. At this time, the piston block compresses the air inside the pads. The compressed air enters the air outlet through the through hole and is ejected. The ejected airflow cools the heat sealing position in time and reduces sticking. Furthermore, the airflow from the vents can be blown away, helping the front and rear heating blocks to separate from the packaging tape. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figures 1-3 , Figures 5-6 and Figures 10-12This embodiment provides the following technical solution, specifically disclosing: a support frame 1 with a frame structure, a feeding component 2 disposed above the support frame 1, and a film feeding component 3 disposed behind the support frame 1. An installation frame 4 is fixedly installed inside the support frame 1. A horizontal sealing component 5 is connected to the installation frame 4. A vertical sealing component 6, corresponding vertically to the horizontal sealing component 5, is disposed inside the support frame 1. A conveying component 7 is disposed behind the vertical sealing component 6. A first lifting mechanism is disposed on the back of the installation frame 4. The horizontal sealing component 5 moves synchronously with the packaging film via the first lifting mechanism. A second lifting mechanism is disposed inside the support frame 1. The vertical sealing component 6 moves synchronously with the packaging film via the second lifting mechanism. A feeding pipe 8, corresponding to the feeding component 2, is fixedly installed inside the support frame 1. A guide plate 9 is fixedly installed outside the feeding pipe 8. The horizontal sealing component 5 includes a main movable frame 501 and a secondary movable frame 502. A front heating block 503 is installed on the inner side of the front end of the movable frame 501, and a rear heating block 504 is installed on the front side of the auxiliary movable frame 502. The auxiliary movable frame 502 and the main movable frame 501 are slidably connected through each other. A drive rod 505 driven by a control motor 507 is provided between the main movable frame 501 and the auxiliary movable frame 502. Connecting rods 506 are rotatably installed at both ends of the drive rod 505. The two connecting rods 506 rotatably connect the main movable frame 501 and the auxiliary movable frame 502 respectively. The longitudinal sealing assembly 6 includes a connecting arm 601, a fixed heating block 602 and a movable heating block 603. The fixed heating block 602 is fixedly connected to the connecting arm 601. The movable heating block 603 forms a sliding structure with the connecting arm 601 through a cylinder. The conveying assembly 7 includes a mounting plate 701 on which a conveyor belt 702 is installed. A pneumatic telescopic rod 703 is installed between the mounting plate 701 and the support frame 1.

[0024] When using the device, firstly, the packaging film roll is installed onto the film feeding assembly 3. Then, the packaging film is guided through the guide plate 9 by the film feeding assembly 3 and the feeding pipe 8. The groove structure inside the guide plate 9 guides the packaging film to the collar structure. Then, the motor in the conveying assembly 7 drives the conveyor belt 702 to rotate. The friction between the conveyor belt 702 and the packaging film is used to pull the packaging film downward (the pneumatic telescopic rod 703 drives the mounting plate 701 to move the conveyor belt 702 to a position close to the packaging film, providing sufficient friction). At the same time as the film is being fed, the feeding assembly 2 quantitatively feeds the material into the feeding pipe 8. The feeding assembly 2 can be replaced according to the actual situation to handle granular materials and powdered materials. The material slides into the inside of the formed packaging film through the feeding pipe 8 to achieve the purpose of feeding. When the packaging film passes through the longitudinal sealing assembly 6, the cylinder in the longitudinal sealing assembly 6 pushes the movable heating block 603 close to the fixed heating block 602. When the heating element 3 approaches the fixed heating block 602, the internal heating wire heats up to achieve longitudinal heat sealing of the packaging film splicing position. After the material is put into the inner side of the packaging belt, the control motor 507 in the horizontal sealing component 5 is activated. The control motor 507 drives the drive rod 505 to rotate. During the rotation of the drive rod 505, it pulls or pushes the main movable frame 501 and the auxiliary movable frame 502 through the connecting rod 506 connected to it, so that the main movable frame 501 and the auxiliary movable frame 502 slide relative to each other. At this time, the front heating block 503 and the rear heating block 504 approach each other and then move away. When the front heating block 503 and the rear heating block 504 approach each other, the internal heating wire is activated to achieve the purpose of transverse heat sealing of the packaging bag. After the transverse sealing is completed, the cylinder pushes the cutting blade 508 to extend out of the front heating block 503 to cut the packaging bag. Finally, after packaging, the product falls to the bottom of the support frame 1. The support frame 1 can be equipped with a weighing device to weigh the packaged product and determine whether it meets the standard.

[0025] Example 2: Please refer to Figures 3-4 In order to improve efficiency, this embodiment provides the following technical solution, which specifically discloses: The first lifting mechanism includes a fixed frame 10 located outside the main movable frame 501. The main movable frame 501 and the fixed frame 10 are slidably connected through each other. The fixed frame 10 is slidably connected to the guide rail 11 fixedly installed on the back of the mounting frame 4. The back of the mounting frame 4 is rotatably mounted with a first lead screw 12 driven by a first servo motor 13. The fixed frame 10 moves up and down relative to the mounting frame 4 through the rotation of the first lead screw 12. The second lifting mechanism includes a connecting frame 14 fixedly installed inside the support frame 1. The connecting frame 14 is rotatably mounted with a second lead screw 15 driven by a second servo motor 16. The connecting arm 601 moves up and down relative to the connecting frame 14 through the rotation of the second lead screw 15.

[0026] During the heat sealing operation, the first servo motor 13 drives the first lead screw 12 to rotate, causing the first lead screw 12 to move the horizontal sealing assembly 5 upward through the fixed frame 10. During the movement of the fixed frame 10, the guide rail 11 is used to guide and maintain the stability of the fixed frame 10 during the movement. At the same time, the second servo motor 16 drives the second lead screw 15 to rotate, causing the second lead screw 15 to move the vertical sealing assembly 6 upward. The movement stroke of the horizontal sealing assembly 5 and the vertical sealing assembly 6 is consistent. When they move to the top, the horizontal sealing assembly 5 and the vertical sealing assembly 6 begin the heat sealing operation (see the detailed working principle in Embodiment 1). During the heat sealing process, the first servo motor 13 and the second servo motor 16 rotate in opposite directions, causing the horizontal sealing assembly 5 and the vertical sealing assembly 6 to move downward. At the same time, the film feeding operation is maintained. The horizontal sealing assembly 5 and the vertical sealing assembly 6 move downward synchronously with the conveyed packaging film, thereby maintaining the film feeding operation during the heat sealing process. The above operation is repeated to form a cycle, improving the overall working efficiency of the device.

[0027] Example 3: Please refer to Figures 7-9 In order to reduce adhesion, this embodiment provides the following technical solution, which specifically discloses: the front heating block 503 is connected to the main movable frame 501 through the pad 509, and the rear heating block 504 is connected to the auxiliary movable frame 502 through the pad 509. Both the front heating block 503 and the rear heating block 504 are provided with air outlet holes 511. The side of the pad 509 is provided with a through hole 510 corresponding to the air outlet hole 511. A piston block 512 is slidably installed inside the pad 509. A return spring 513 is fixedly installed between the piston block 512 and the inner wall of the pad 509. The piston block 512 moves relative to the pad 509 to squeeze out air.

[0028] The sliding between the main movable frame 501 and the auxiliary movable frame 502 has two strokes. The first stroke makes the front heating block 503 and the rear heating block 504 fit together for heat sealing. After heat sealing, the second stroke begins. At this time, the front heating block 503 and the rear heating block 504 continue to move closer to generate a pressing force. This pressing force is applied to the pad 509, causing the pad 509 to move relative to the piston block 512. At this time, the piston block 512 compresses the air inside the pad 509. The compressed air inside the pad 509 is discharged through the through hole 510 and the air outlet 511. The discharged air is used to cool the heat-sealed position in time to form solidification and reduce the subsequent sticking. After the second stroke is completed, the motor 507 is controlled to rotate in the opposite direction to move the front heating block 503 and the rear heating block 504 away from each other. This process is repeated to form continuous operation.
