Description

Technical Field

[0001] The utility model relates to a packaging machine, in particular to a vertical packaging machine. Background Art

[0002] A vertical packaging machine is an automated device mainly used for packaging various products and is widely used because of its advantages of high efficiency and high production efficiency. In the packaging process of the vertical packaging machine, the packaging film is fed by a film feeding mechanism and the plastic film forms a tubular shape through a cylinder. Then, the side is sealed by a thermal longitudinal sealing mechanism, and at the same time, the packaged product is injected into the bag. Finally, the transverse sealing mechanism performs thermal transverse sealing and cuts the packaging position according to the color mark photoelectric detection device. At present, when the tubular packaging film moves downward in the used packaging machine, a film pulling mechanism still needs to be additionally arranged to pull it, which results in a complex structure of the packaging machine, and thus greater difficulty in maintenance, leading to high maintenance costs. Content of the Utility Model

[0003] The utility model provides a vertical packaging machine, which solves the technical problem of complex structure, and provides the following technical solutions:

[0004] A vertical packaging machine includes a frame and a controller. A film feeding mechanism, a filling mechanism, and a sealing mechanism are arranged on the frame. The film feeding mechanism, the filling mechanism, and the sealing mechanism are all electrically connected to the controller through wires. An installation box is arranged on the frame. The film feeding mechanism is installed on one side of the frame far from the installation box. The filling mechanism is installed on the top of the installation box. A bag making machine is installed inside the frame, and the bag making machine is hollow along the height direction. The upper end of the bag making machine extends between the film feeding mechanism and the filling mechanism. The filling mechanism is communicated with a discharge pipe, and the other end of the discharge pipe extends into the bag making machine. The sealing mechanism is arranged on one side of the frame close to the installation box. The feature is that the sealing mechanism includes a longitudinal sealing mechanism and a transverse sealing and cutting mechanism. The longitudinal sealing mechanism is arranged on one side of the bag making machine, and the transverse sealing and cutting mechanism is arranged below the bag making machine. A driving mechanism is arranged inside the installation box, and the driving mechanism is in linkage cooperation with the transverse sealing and cutting mechanism to make the transverse sealing and cutting mechanism move along the height direction of the frame.

[0005] By adopting the above technical solutions, through the setting of the driving mechanism, the controller controls the driving mechanism to drive the transverse sealing and cutting mechanism to move along the height direction of the frame. This enables the driving transverse sealing and cutting mechanism to perform transverse sealing on the packaging film and at the same time traction the packaging film to move downward. Furthermore, it makes the packaging machine not need to set a film pulling mechanism below the longitudinal sealing mechanism, which will greatly simplify the structure of the packaging machine, thereby reducing the maintenance cost.

[0006] Furthermore, a first support frame is provided on the installation box, and the lower end of the bag maker passes through the support frame and is arranged above the transverse sealing and cutting mechanism. The first support frame includes three first side plates and one second side plate. The three first side plates are connected end to end in sequence to form a "U" shape, and the two ends of the second side plate are in sliding fit with the two parallel first side plates. A first cylinder is provided on the side wall surface of the second side plate close to the bag maker. The first cylinder is linked with an assisting plate, and the other side of the assisting plate has the same shape as the outer periphery of the bag maker.

[0007] By adopting the above technical solution, through the arrangement of the second side plate, since the second side plate is in sliding fit with the first side plates at both ends, the position of the assisting plate can be initially adjusted greatly by adjusting the position of the second side plate, and then the position of the assisting plate can be adjusted slightly for the second time by the first cylinder. Furthermore, when the packaging film moves along the outer periphery of the bag maker, by controlling the first cylinder to drive the assisting plate to move, the position of the packaging film can be stabilized, so as to ensure that the produced finished product has better aesthetics.

[0008] Furthermore, the longitudinal sealing mechanism includes a second cylinder and a first hot melting component in linkage fit. The second cylinder is arranged on the first side plate parallel to the second side plate among the three first side plates. The output shaft of the second cylinder is linked with a transfer plate, and a plurality of guide rods are arranged on the other side of the transfer plate. Each guide rod is in sliding fit with the transfer plate, and the other end of each guide rod is fixedly fitted with the first hot melting component. A spring is sleeved on each guide rod, and one end of the spring abuts against the side wall surface of the first hot melting component. When the second cylinder is in the initial state, the spring is in an idle state, and the other end of the spring abuts against the side wall surface of the transfer plate.

[0009] By adopting the above technical solution, through the arrangement of the spring, during the process of controlling the second cylinder to start and drive the first hot melting component to move, the spring will disperse a part of the thrust applied by the transfer plate, thereby avoiding excessive impact force of the first hot melting component on the packaging film, so as to ensure the aesthetics of the produced finished product and extend the service life of this packaging machine.

[0010] Further, a second support frame is provided on the mounting box below the first support frame. The driving mechanism includes a motor. The second support frame is in linkage cooperation with the motor through a linkage mechanism. The second support frame includes four third side plates connected end to end in sequence, so that the second support frame is arranged in a "mouth" shape. The transverse sealing and cutting mechanism includes a second hot melt assembly and a third hot melt assembly. A third cylinder is fixedly provided on the third side plate below the first cylinder, and the third cylinder is in linkage cooperation with the second hot melt assembly. A cutting knife is provided on one side of the second hot melt assembly away from the third cylinder. A fourth cylinder is correspondingly provided on the third side plate corresponding to the lower side of the second cylinder. The output shaft of the fourth cylinder drives the third hot melt assembly in a linkage manner, and the output shaft of the fourth cylinder and the output shaft of the third cylinder are arranged to approach each other.

[0011] Further, the linkage structure includes a first link and a second link hinged to each other. The other end of the first link is fixedly fitted with the output shaft of the motor, and the other end of the second link is fixedly fitted with the second support frame. Two vertically arranged slide rails are provided on one side of the frame close to the mounting box. Two sliders are provided on the second support frame. The two sliders are respectively corresponding to the two slide rails and are in sliding fit.

[0012] Further, two symmetrically arranged fifth cylinders are provided on the second support frame, and the two fifth cylinders are respectively arranged above the third cylinder and the fourth cylinder. The output shafts of the two fifth cylinders are arranged to approach each other. The output shafts of the two fifth cylinders are both linked with pressing plates, and two pressing heads are respectively provided on the side walls of the two pressing plates close to each other.

[0013] By adopting the above technical solution, through the cooperation of the fifth cylinder and the pressing plate, during the downward movement of the packaging film after longitudinal sealing, the position of the pressing plate can be adjusted by controlling the fifth cylinder, and then the positions of the two pressing heads can be controlled, ensuring that the packaging film moves downward between the two rows of pressing heads, avoiding the unappealing appearance of the produced finished products due to the deformation of the packaging film, and thus ensuring the quality and aesthetics of the finished products.

[0014] In summary, the present application has the following beneficial effects:

[0015] 1. Through the setting of the driving mechanism, the controller controls the driving mechanism to drive the transverse sealing and cutting mechanism to move along the height direction of the frame. This enables the transverse sealing and cutting mechanism to perform transverse sealing on the packaging film while also pulling the packaging film downward. As a result, the present packaging machine does not need to be provided with a film pulling mechanism below the longitudinal sealing mechanism, which will greatly simplify the structure of the present packaging machine and thus reduce the maintenance cost;

[0016] 2. Through the setting of the second side plate, since the second side plate and the first side plates at both ends are in a sliding fit, the position of the auxiliary plate can be initially adjusted significantly by adjusting the position of the second side plate. Then, the position of the auxiliary plate can be adjusted slightly for the second time by the first air cylinder. Furthermore, when the packaging film moves along the outer periphery of the bag-making machine, the position of the auxiliary plate is driven to move by controlling the first air cylinder, so as to stabilize the position of the packaging film, thereby ensuring that the produced finished product has better aesthetics.

[0017] 3. Through the setting of the spring, during the process of controlling the second air cylinder to start and drive the first hot-melt assembly to move, the spring will disperse part of the thrust exerted by the adapter plate, thereby avoiding excessive impact force of the first hot-melt assembly on the packaging film, and ensuring the aesthetics of the produced finished product and extending the service life of this packaging machine.

[0018] 4. Through the cooperation of the fifth air cylinder and the pressing plate, during the process of the packaging film moving downward after longitudinal sealing, the position of the pressing plate can be adjusted by controlling the fifth air cylinder, and then the positions of the two pressing heads can be controlled to ensure that the packaging film moves downward between the two rows of pressing heads, avoiding the un-aesthetic appearance of the produced finished product caused by the deformation of the packaging film, and thus ensuring the quality and aesthetics of the finished product.

[0027] The following further elaborates on this application with reference to the accompanying drawings.

[0028] To make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model is further described below in conjunction with the specific implementation manners.

[0029] In a specific embodiment, referring to Figure 1-7 , a vertical packaging machine includes a frame 1 and a controller. A film feeding mechanism 2, a filling mechanism 3 and a sealing mechanism are arranged on the frame 1. The film feeding mechanism 2, the filling mechanism 3 and the sealing mechanism are all electrically connected to the controller through wires. An installation box 4 is arranged on the frame 1. The film feeding mechanism 2 is installed on one side of the frame 1 away from the installation box 4. The filling mechanism 3 is installed on the top of the installation box 4. A bag making device 5 is installed inside the frame 1, and the bag making device 5 is hollow along the height direction. The upper end of the bag making device 5 extends between the film feeding mechanism 2 and the filling mechanism 3. The filling mechanism 3 is communicated with a discharge pipe 6, and the other end of the discharge pipe 6 extends into the bag making device 5. A flow control component is arranged on the discharge pipe 6 and is connected to the controller. By controlling the opening or closing of the flow control component through the controller, the technical means of discharging and stopping the discharge of materials is achieved, which belongs to common knowledge and will not be elaborated here. The structures of the film feeding mechanism 2 and the filling mechanism 3 both belong to common knowledge and will not be elaborated here. For example, in the patent with the application number CN202221492964.9, the sealing mechanism is arranged on one side of the frame 1 close to the installation box 4. The sealing mechanism includes a longitudinal sealing mechanism 7 and a transverse sealing and cutting mechanism 8. The longitudinal sealing mechanism 7 is arranged on one side of the bag making device 5. The transverse sealing and cutting mechanism 8 is arranged below the bag making device 5. A driving mechanism 9 is arranged inside the installation box 4. The driving mechanism 9 and the transverse sealing and cutting mechanism 8 are in a linkage cooperation, so that the transverse sealing and cutting mechanism 8 moves along the height direction of the frame 1.

[0030] The controller controls the drive mechanism 9 to drive the transverse sealing and cutting mechanism 8 to move in the height direction of the frame 1. This enables the transverse sealing and cutting mechanism 8 to perform transverse sealing on the packaging film while also pulling the packaging film downward. As a result, there is no need to set up a film pulling mechanism below the longitudinal sealing mechanism 7 in this packaging machine, which will greatly simplify the structure of this packaging machine and thus reduce the maintenance cost.

[0031] A first support frame 10 is provided on the installation box 4, and the lower end of the bag making machine 5 passes through the support frame and is arranged above the transverse sealing and cutting mechanism 8. The first support frame 10 includes three first side plates 1001 and one second side plate 1002. The three first side plates 1001 are sequentially connected end to end to form a "U" shape, and the two ends of the second side plate 1002 are in sliding fit with two parallel first side plates 1001; a first cylinder 11 is provided on the side wall surface of the second side plate 1002 close to the bag making machine 5. The first cylinder 11 is linked with an assisting plate 12, and the other side of the assisting plate 12 has the same shape as the outer periphery of the bag making machine 5; because the second side plate 1002 and the two first side plates 1001 at both ends are in sliding fit, the position of the assisting plate 12 can be initially adjusted greatly by adjusting the position of the second side plate 1002, and then the position of the assisting plate 12 can be adjusted slightly for the second time by the first cylinder 11. Thus, when the packaging film moves along the outer periphery of the bag making machine 5, by controlling the first cylinder 11 to drive the assisting plate 12 to move, the position of the packaging film can be stabilized, thereby ensuring that the produced finished product has better aesthetics.

[0032] The longitudinal sealing mechanism 7 includes a second cylinder 701 and a first hot melt assembly 702 that are in linked cooperation. The second cylinder 701 is arranged on the first side plate 1001 among the three first side plates 1001 and the first side plate 1001 parallel to the second side plate 1002. The output shaft of the second cylinder 701 is linked with an adapter plate 13. The other side of the adapter plate 13 is provided with a plurality of guide rods 14, and each guide rod 14 is in sliding fit with the adapter plate 13. The other end of each guide rod 14 is fixedly fitted with the first hot melt assembly 702. A spring 15 is sleeved on each guide rod 14, and one end of the spring 15 abuts against the side wall surface of the first hot melt assembly 702. When the second cylinder 701 is in the initial state, the spring 15 is in an idle state, and the other end of the spring 15 abuts against the side wall surface of the adapter plate 13. The specific structure and connection method of the longitudinal sealing mechanism 7 have been described in detail in other related patents and will not be elaborated here; during the process of controlling the second cylinder 701 to start and drive the first hot melt assembly 702 to move, the spring 15 will disperse part of the thrust exerted by the adapter plate 13, thereby avoiding excessive impact force of the first hot melt assembly 702 on the packaging film, and thus ensuring the aesthetics of the produced finished product and extending the service life of this packaging machine.

[0033] A second support frame is arranged on the installation box 4 below the first support frame 10, and the driving mechanism 9 includes a motor. The second support frame is linked with the motor through a connecting rod mechanism 16, and the second support frame includes four third side plates 17 which are connected end to end in sequence, so that the second support frame is arranged in a "mouth" shape; the transverse sealing and cutting mechanism 8 includes a second hot melt component 801 and a third hot melt component 802, and a third cylinder 18 is fixedly arranged on the third side plate 17 below the first cylinder 11, and the third cylinder 18 and the second hot melt component 801 are linked, and a cutting knife 19 is arranged on the side of the second hot melt component 801 away from the third cylinder 18, and a fourth cylinder 20 is correspondingly arranged on the corresponding third side plate 17 below the second cylinder 701, and the output shaft in the fourth cylinder 20 is linked with the third hot melt component 802, and the output shaft in the fourth cylinder 20 and the output shaft in the third cylinder 18 are arranged close to each other.

[0034] The connecting rod structure includes a hinged first connecting rod 1601 and a second connecting rod 1602, the other end of the first connecting rod 1601 is fixedly matched with the output shaft of the motor, and the other end of the second connecting rod 1602 is fixedly matched with the second supporting frame; two vertically arranged slide rails 21 are arranged on one side of the frame 1 close to the installation box 4, and two sliders 22 are arranged on the second supporting frame, and the two sliders 22 correspond to the positions of the two slide rails 21 and are slidably matched; two symmetrically arranged fifth cylinders 23 are arranged on the second supporting frame, and the two fifth cylinders 23 are respectively arranged Above the third cylinder 18 and the fourth cylinder 20, the output shafts in the two fifth cylinders 23 are arranged close to each other, and the output shafts in the two fifth cylinders 23 are linked with a pressure plate 24, and two pressure heads 25 are respectively arranged on the side wall surfaces close to each other in the two pressure plates 24; in the process of the packaging film moving downward after longitudinal sealing, the position of the pressure plate 24 can be adjusted by controlling the fifth cylinder 23, and then the position of the pressure heads 25 on both sides can be controlled to ensure that the packaging film moves downward from between the two rows of pressure heads 25, so as to avoid the unsightly finished product produced due to deformation of the packaging film, thereby ensuring the quality and aesthetics of the finished product.

[0035] Operation principle: The rolled packaging film passes through the film unwinding and is set in a cylindrical shape along the outer periphery of the bag making device 5. At this time, there is a section of overlapping packaging film in the vertical direction. At this time, the second cylinder 701 is controlled to drive the first hot melt assembly 702 to move towards the packaging film to complete the longitudinal sealing operation of the packaging film. At this time, the controller controls the motor to drive the transverse sealing and cutting mechanism 8 to move up and down, thereby pulling the packaging film downwards. When the longitudinally sealed section of the packaging film enters the second support frame, the controller controls the third cylinder 18 and the fourth cylinder 20 to start and drive the second hot melt assembly 801 and the third hot melt assembly 802 to move towards each other to complete the transverse sealing operation of the packaging film and cut in the middle of the seal. After that, the controller controls the discharge pipe 6 to discharge materials. After the discharging is completed, the third cylinder 18 and the fourth cylinder 20 are controlled again to drive the second hot melt assembly 801 and the third hot melt assembly 802 to move towards each other to complete the transverse sealing and cutting operations. At this time, the dropped ones are the finished products.
