Description

Technical Field

[0001] The utility model relates to a packaging machine, in particular to a traction transverse sealing and cutting mechanism for a packaging machine. Background Art

[0002] As the last step in the food processing and packaging process, the transverse sealing and cutting mechanism first seals transversely, then cuts transversely, and finally obtains finished products. However, during the transverse sealing process, the packaging film needs to continuously move downward for the transverse sealing and cutting mechanism to operate. However, the existing transverse sealing and cutting mechanism does not have the function of pulling the packaging film downward, and a separate film pulling mechanism still needs to be set up additionally, which makes the structure of the packaging machine more complex, the maintenance difficulty greater, and the cost input higher. Content of the Utility Model

[0003] The utility model provides a traction transverse sealing and cutting mechanism for a packaging machine, which solves the technical problems of not having the function of pulling the packaging film downward, complex structure, great maintenance difficulty and high cost input, and provides the following technical solutions:

[0004] A traction transverse sealing and cutting mechanism for a packaging machine includes a support device fixed on the packaging machine, and a transverse sealing and cutting mechanism body is arranged on the support device. The feature is that the transverse sealing and cutting mechanism body and the support device are in sliding fit, and there is a driving mechanism on the packaging machine, and the driving mechanism is connected to the transverse sealing and cutting mechanism body in a linkage manner. The driving mechanism is used to drive the transverse sealing and cutting mechanism body to move along the height direction of the support device.

[0005] By adopting the above technical solution, through the setting of the sliding fit between the transverse sealing and cutting mechanism body and the support device, when the transverse sealing and cutting mechanism body seals and cuts the packaging film transversely, the driving device can be used to drive the transverse sealing and cutting mechanism body to move up and down, thereby pulling the packaging film to move downward. This makes the transverse sealing and cutting mechanism body have the functions of transverse sealing and cutting, and also has the function of pulling the film, which eliminates the need to set up a separate film pulling mechanism in the packaging machine, thereby simplifying the structure of the packaging machine, reducing the maintenance difficulty of the device and reducing the cost input.

[0006] Furthermore, the support device includes two support plates with the same structure; on the side wall surface of each support plate close to the transverse sealing and cutting mechanism body, a slide rail is fixedly arranged; at both ends of the transverse sealing and cutting mechanism body close to the support device, sliders are respectively arranged, and each slider is adapted to the corresponding slide rail on one side.

[0007] Furthermore, the driving mechanism includes a motor, the output shaft of the motor is connected with a connecting rod mechanism, and the other end of the connecting rod mechanism is fixedly connected with one end of the transverse sealing and cutting mechanism body close to the support device;

[0008] The linkage mechanism includes a first link body and a second link body. One end of the first link body is fixedly connected to the output shaft of the motor. The other end of the first link body is hinged to one end of the second link body. The other end of the second link body is fixedly connected to the body of the transverse sealing and cutting mechanism.

[0009] By adopting the above technical solution, through the setting of the linkage mechanism, after the motor is started, it drives the first link body to rotate synchronously. Since the other end of the first link body is hinged to the second link body, the first link body drives the second link body to rotate, causing the other end of the second link body to rise. Then, the second link body drives the body of the transverse sealing and cutting mechanism to move upward. After rising, by controlling the rotation direction of the motor, the body of the transverse sealing and cutting mechanism descends, thereby completing the rising and falling of the body of the transverse sealing and cutting mechanism, and thus completing the film pulling operation. The structure is simple and the operation is fast, thereby reducing the subsequent maintenance difficulty and cost.

[0010] Further, a motor base is arranged below the body of the transverse sealing and cutting mechanism. The motor base is arranged in an "L" shape. The horizontal section of the motor base is fixedly installed on the packaging machine. The motor is installed at the top of the vertical section of the motor base. The output shaft of the motor passes through the motor base and extends out of the motor base.

[0011] Further, the body of the transverse sealing and cutting mechanism includes a support frame and a first cylinder arranged inside the support frame. The output shaft of the first cylinder faces the support device. Guide rods are arranged on the side wall surfaces corresponding to both sides of the first cylinder. The other ends of the two guide rods are arranged on the other side wall surface inside the support frame. A first heat fusion component and a second heat fusion component are slidably arranged on the two guide rods. The output shaft of the first cylinder corresponds to the middle part of the first heat fusion component. A second cylinder is arranged on the support frame. The output shaft of the second cylinder passes through the support frame and extends to one side of the second heat fusion component. The output shaft of the second cylinder corresponds to the middle part of the second heat fusion component. A cutter is arranged in the middle of the side wall surface of the first heat fusion component close to the second heat fusion component. The length direction of the cutter is the same as the length direction of the heat fusion component, and the cutting edge of the cutter faces the second heat fusion component.

[0012] By adopting the above technical solution, through the setting of the first heat fusion component and the second heat fusion component at both ends, when the packaging film passes between the first heat fusion component and the second heat fusion component, the first cylinder and the second cylinder drive and respectively push the first heat fusion component and the second heat fusion component to move towards each other, thereby completing the sealing of the packaging film from both sides. At the same time of sealing, the cutter on the first heat fusion component cuts the middle line position of the seal of the packaging film. After cutting, the finished product drops, thus completing the production. The structure is simple and the production efficiency is high.

[0013] Further, "L"-shaped connecting plates are symmetrically arranged on the support frame. The vertical sections of the two connecting plates are fixedly connected to the support frame, and third cylinders are fixedly connected to the horizontal sections of the two connecting plates. The output shafts of the two third cylinders are both connected with pressing plates, and pressing heads are arranged on the side walls of the two pressing plates that are close to each other.

[0014] By adopting the above technical solution, through the setting of the pressing heads, during the downward movement of the packaging film, by controlling the third cylinders to adjust the positions of the corresponding pressing heads, the moving position of the packaging film can be guided and limited, thereby ensuring the aesthetics of the subsequent finished products.

[0015] In summary, the present application includes the following beneficial effects:

[0016] 1. Through the sliding fit between the body of the transverse sealing and cutting mechanism and the supporting device, when the body of the transverse sealing and cutting mechanism performs transverse sealing and cutting on the packaging film, the driving device can drive the body of the transverse sealing and cutting mechanism to move upward and downward, thereby pulling the packaging film to move downward. This enables the body of the transverse sealing and cutting mechanism to not only have the functions of transverse sealing and cutting but also have a film pulling function, eliminating the need to separately set a film pulling mechanism in the packaging machine, thus simplifying the structure of the packaging machine, reducing the maintenance difficulty of the device, and reducing the cost investment.

[0017] 2. Through the setting of the link mechanism, after the motor is started, it drives the first link body to rotate synchronously. Since the other end of the first link body is hinged to the second link body, the first link body drives the second link body to rotate, causing the other end of the second link body to rise. Then, the second link body drives the body of the transverse sealing and cutting mechanism to move upward. After rising, by controlling the rotation direction of the motor, the body of the transverse sealing and cutting mechanism descends, thereby completing the up and down movement of the body of the transverse sealing and cutting mechanism and thus completing the film pulling operation. The structure is simple and the operation is fast, thereby reducing the subsequent maintenance difficulty and cost.

[0018] 3. Through the setting of the first hot melt assembly and the second hot melt assembly at both ends, when the packaging film passes between the first hot melt assembly and the second hot melt assembly, the first cylinder and the second cylinder drive and respectively push the first hot melt assembly and the second hot melt assembly to move towards each other, thereby completing the sealing of the packaging film from both sides; while sealing, the cutter on the first hot melt assembly cuts the midline position of the seal of the packaging film, and the finished product drops after cutting, thus completing the production. The structure is simple and the production efficiency is high.

[0019] 4. Through the setting of the pressing heads, during the downward movement of the packaging film, by controlling the third cylinders to adjust the positions of the corresponding pressing heads, the moving position of the packaging film can be guided and limited, thereby ensuring the aesthetics of the subsequent finished products.

[0026] The following further elaborates on this application in conjunction with the accompanying drawings.

[0027] 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 specific implementation manners.

[0028] In a specific embodiment, referring to Figures 1 - 5 , a traction transverse sealing and cutting mechanism for a packaging machine includes a support device 1 fixed on the packaging machine. There is a transverse sealing and cutting mechanism body on the support device 1. The transverse sealing and cutting mechanism body and the support device 1 are in sliding fit. There is a driving mechanism 2 on the packaging machine, and the driving mechanism 2 and the transverse sealing and cutting mechanism body are in linkage connection. The driving mechanism 2 is used to drive the transverse sealing and cutting mechanism body to move along the height direction of the support device 1; when the transverse sealing and cutting mechanism body performs transverse sealing and cutting on the packaging film, the transverse sealing and cutting mechanism body can be driven by the driving device to move up and down, thereby pulling the packaging film to move downward, so that in addition to having the functions of transverse sealing and cutting, this transverse sealing and cutting mechanism body also has a film pulling function, which eliminates the need to separately set up a film pulling mechanism in the packaging machine, thereby simplifying the structure of this packaging machine, reducing the maintenance difficulty of this device and reducing the cost investment.

[0029] The supporting device 1 includes two support plates with the same structure; on the side wall surface of each support plate close to the body of the transverse sealing and cutting mechanism, a slide rail 3 is fixedly arranged; at both ends of the body of the transverse sealing and cutting mechanism close to the supporting device 1, sliders 4 are respectively arranged, and each slider 4 is adapted to the corresponding slide rail 3 on one side.

[0030] Below the body of the transverse sealing and cutting mechanism, a motor base 6 is arranged. The motor base 6 is arranged in an "L" shape. The horizontal section of the motor base 6 is fixedly installed on the packaging machine, and the motor is installed at the top of the vertical section of the motor base 6. The output shaft of the motor passes through the motor base 6 and extends outside the motor base 6.

[0031] The body of the transverse sealing and cutting mechanism includes a support frame 7 and a first cylinder 8 arranged inside the support frame 7. The output shaft of the first cylinder 8 faces the supporting device 1. Guide rods 9 are arranged on the side wall surfaces corresponding to both sides of the first cylinder 8. The other ends of the two guide rods 9 are arranged on the other side wall surface inside the support frame 7. A first heat fusion component 10 and a second heat fusion component 11 are slidably arranged on the two guide rods 9. The output shaft of the first cylinder 8 corresponds to the middle part of the first heat fusion component 10. A second cylinder 12 is arranged on the support frame 7. The output shaft of the second cylinder 12 passes through the support frame 7 and extends to one side of the second heat fusion component 11, and the output shaft of the second cylinder 12 corresponds to the middle part of the second heat fusion component 11; in the first heat fusion component 10, a cutter 13 is arranged in the middle of the side wall surface close to the second heat fusion component 11. The length direction of the cutter 13 is the same as the length direction of the heat fusion component, and the cutting edge of the cutter 13 faces the second heat fusion component 11; the specific connection structures of the first cylinder 8 and the first heat fusion component 10, and the second cylinder 12 and the second heat fusion component 11 are all common knowledge and will not be elaborated here. The specific structures of the first heat fusion component 10 and the second heat fusion component 11 are common technical means in this field and will not be elaborated here. The first heat fusion component 10 and the second heat fusion component 11 can be selected with models that can heat the packaging film to achieve the heat sealing effect and will not be elaborated here; when the packaging film passes between the first heat fusion component 10 and the second heat fusion component 11, the first cylinder 8 and the second cylinder 12 are driven to respectively push the first heat fusion component 10 and the second heat fusion component 11 to move towards each other, so as to complete the sealing of the packaging film from both sides; at the same time of sealing, the cutter 13 on the first heat fusion component 10 will cut the middle line position of the seal of the packaging film. After cutting, the finished products fall, thus completing the production. The structure is simple and the production efficiency is high.

[0032] The driving mechanism 2 includes a motor. The output shaft of the motor is connected to a connecting rod mechanism 5, and the other end of the connecting rod mechanism 5 is fixedly connected to one end of the transverse sealing and cutting mechanism body close to the supporting device 1. The connecting rod mechanism 5 includes a first connecting rod body 501 and a second connecting rod body 502. One end of the first connecting rod body 501 is fixedly connected to the output shaft of the motor, and the other end of the first connecting rod body 501 is hinged to one end of the second connecting rod body 502. The other end of the second connecting rod body 502 is fixedly connected to the transverse sealing and cutting mechanism body. After the motor is started, it drives the first connecting rod body 501 to rotate synchronously. Since the other end of the first connecting rod body 501 is hinged to the second connecting rod body 502, the first connecting rod body 501 drives the second connecting rod body 502 to rotate, causing the other end of the second connecting rod body 502 to rise. Then, the second connecting rod body 502 drives the transverse sealing and cutting mechanism body to move upward. After rising, by controlling the rotation direction of the motor, the transverse sealing and cutting mechanism body descends. Thus, the rising and falling of the transverse sealing and cutting mechanism body are completed, and the film pulling operation is completed. The structure is simple and the operation is fast, thereby reducing the subsequent maintenance difficulty and cost.

[0033] On the support frame 7, there are symmetrically arranged "L"-shaped connecting plates 14. The vertical sections of the two connecting plates 14 are both fixedly connected to the support frame 7, and third cylinders 15 are fixedly connected to the horizontal sections of the two connecting plates 14. The output shafts of the two third cylinders 15 are both connected to pressing plates 16, and pressing heads 17 are arranged on the side walls of the two pressing plates 16 that are close to each other. By controlling the third cylinders 15, the positions of the corresponding pressing heads 16 are adjusted, thereby guiding and limiting the moving position of the packaging film, and ensuring the aesthetics of the subsequent finished products.

[0034] It is common general knowledge that a controller is provided on the packaging machine and is connected to the motor, the first cylinder 8, and the second cylinder 12, so that the controller can control the motor, the first cylinder 8, and the second cylinder 12 respectively, and no further elaboration will be made here.

[0035] Operating principle: After the packaging film is longitudinally sealed by the longitudinal sealing mechanism, the motor is started to drive the first connecting rod body 501 to rotate, and the second connecting rod body 502 drives the second connecting rod body 502 to rotate, thereby driving the packaging film to move downward from the longitudinal sealing mechanism. During the downward movement of the packaging film, the pressing head 17 will limit the packaging film. When the packaging film moves downward, the first cylinder 8 and the second cylinder 12 are started to drive the first hot melting component 10 and the second hot melting component 11 to move towards each other, thereby completing the heat sealing operation and the cutting operation. When the cutting is completed, the finished product drops. At this time, the motor reversely controls the rotation of the first connecting rod body 501 to make the transverse sealing and cutting mechanism body move upward. After moving to the designated position, the transverse sealing and cutting mechanism body is again driven by the motor to move downward to complete the downward movement of the packaging film, and the transverse sealing and cutting mechanism body continuously moves upward and downward in a cyclic manner.
