Description

Technical Field

[0001] This utility model relates to the field of vertical packaging machine technology, specifically to an improved horizontal sealing device for a vertical packaging machine. Background Technology

[0002] Vertical packaging machines are automated packaging equipment that unfolds a roll of packaging film vertically to complete steps such as forming, filling, sealing, and cutting, packaging materials into individual packaging bags. The horizontal sealing device is a key component of vertical packaging machines, responsible for heating and sealing the horizontal edges of the packaging bags to form independent packaging units.

[0003] Based on the above, the following problems were found: the horizontal sealing device of the current vertical packaging machine usually uses two electrically heated heat sealing plates to heat and seal the packaging bag. After sealing, the molten packaging bag is easy to stick to the heat sealing plate and cannot be easily peeled off, making it inconvenient to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an improved horizontal sealing device for a vertical packaging machine, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide an improved horizontal sealing device for a vertical packaging machine to solve the problems mentioned in the background art.

[0006] An improved horizontal sealing device for a vertical packaging machine includes a control component. A heat-sealing component is located on one side of the control component, and a peeling component is located on the top of the heat-sealing component. The control component includes a protective box. The heat-sealing component includes two movable plates, with a heat-sealing panel on one side of each movable plate. The peeling component includes two air ducts, each with an air inlet at one end. The two air ducts are respectively located on the top of the two movable plates. An exhaust slot is located at the bottom of each air duct, facing the top edge of the bottom heat-sealing panel. Mounting brackets are fixedly installed at both ends of the two air ducts, with one end of each mounting bracket fixedly installed on the top of the protective box.

[0007] By adopting the above technical solution, the control components facilitate the control of the heat-sealing component, enabling it to heat-seal the packaging bag. The heat-sealing component facilitates the heat-sealing of the packaging bag, while the peeling component facilitates the ejection of high-speed airflow to peel the sealed packaging bag from the heat-sealing panel surface. The protective box provides a suitable installation base and protects the internal structure. The heat-sealing panel allows for direct contact with the packaging material for heat sealing. The air inlet facilitates the guidance of high-speed airflow into the air duct. The air duct is designed to guide airflow from the exhaust duct, allowing it to be blown out in a relatively uniform curtain-like manner between the packaging bag and the heat-sealing panel. This helps to peel the packaging bag off the heat-sealing panel during the heat-sealing process and also accelerates the cooling and hardening of the heat-sealed portion of the packaging bag, facilitating subsequent cutting. The mounting bracket allows for the secure connection between the peeling component and the control component, enabling the two air ducts to be fixedly installed on top of the heat-sealing component. Furthermore, the mounting bracket ensures that the air ducts do not obstruct the downward movement of the packaging bag, facilitating the heat-sealing component's heat sealing process.

[0008] Furthermore, both air intake ports are connected to connecting pipes, and the two connecting pipes are connected to a three-way solenoid valve, with an air source port on one side of the three-way solenoid valve.

[0009] By adopting the above technical solution, the setting of the air source interface facilitates the connection to an external high-pressure air source. The three-way solenoid valve is used to control the opening and closing of the air path and synchronously introduce the airflow into the two air guide pipes to control the blowing action of the two exhaust slots, so that the airflow is blown out when the heat sealing component unfolds after completing the heat sealing action.

[0010] Furthermore, threaded rods are rotatably connected to both ends of the protective box, and threaded sleeves are fixedly installed at both ends of the movable plate. The threaded sleeves are threadedly connected to the threaded rods, and the thread directions at both ends of the threaded rods are opposite.

[0011] By adopting the above technical solution, the opposite thread directions at both ends of the threaded rod facilitate the rotation control of the two moving plates to move closer or further apart. When they move closer, they drive the two heat-sealing panels to heat and pressurize the packaging bag, thereby achieving the heat-sealing action.

[0012] Furthermore, one end of each of the two threaded rods is rotatably connected to a stabilizing bar, and both ends of the protective box are provided with mounting ears.

[0013] By adopting the above technical solution and using the mounting ears, the device can be easily fixed at the bottom of the vertical packaging machine, facilitating heat sealing of the packaging bags. The stabilizing strip helps to improve the installation stability of the two threaded rods.

[0014] Furthermore, a control motor is fixedly installed inside the protective box, and a first worm gear is fixedly installed at the output end of the control motor, with the first worm gear meshing with a first worm wheel.

[0015] By adopting the above technical solution and controlling the motor settings, it is easy to control the motor to drive the first worm gear to rotate.

[0016] Furthermore, a drive shaft is fixedly installed in the middle of the first worm gear, and the drive shaft is rotatably connected to the protective box.

[0017] By adopting the above technical solution, the transmission shaft is designed to facilitate the rotation of the first worm gear, which in turn drives the transmission shaft to rotate.

[0018] Furthermore, a second worm is fixedly installed at both ends of the transmission shaft, and the second worm is meshed with a second worm wheel, which is fixedly connected to the threaded rod.

[0019] By adopting the above technical solution, the setting of the second worm gear facilitates the rotation of the transmission shaft, which in turn drives the second worm to rotate, thereby controlling the synchronous rotation of the two threaded rods.

[0020] Furthermore, an installation groove is provided on one side of each of the two movable plates, and several ceramic heating elements are fixedly installed inside the installation groove.

[0021] By adopting the above technical solution, the ceramic heating elements are arranged in a rectangular array and can be independently controlled, avoiding insufficient temperature at both ends of the heat-sealing panel due to rapid heat dissipation and overheating in the middle due to heat accumulation. This achieves a uniform temperature field across the entire heat-sealing panel and improves the heat-sealing effect.

[0022] Furthermore, an intermediate layer is fixedly installed on the outer side of the ceramic heating element, and one side of the intermediate layer is fixedly connected to the heat-sealing panel. The intermediate layer is made of copper, and the heat-sealing panel is made of high-strength mold steel.

[0023] By adopting the above technical solution, the intermediate layer is made of copper and the heat-sealing panel is made of high-strength mold steel. This allows the high thermal conductivity copper intermediate layer to efficiently transfer the heat from the ceramic heating element to the surface of the heat-sealing panel, reducing heat loss. The high-strength mold steel has high hardness, wear resistance, and resistance to thermal fatigue, making it suitable for repeated heating and cooling cycles. It is used for heat sealing in direct contact with packaging materials, thus preventing sticking and extending service life.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows: The control component facilitates the control of the heat-sealing component, enabling it to heat-seal the packaging bag. The heat-sealing component facilitates the heat-sealing of the packaging bag. The peeling component facilitates the blowing of high-speed airflow, allowing the sealed packaging bag to peel off from the heat-sealing panel surface. The protective box provides a suitable installation base and protects the internal structure. The heat-sealing panel allows for direct contact with the packaging material for heat sealing. The air inlet facilitates the guidance of high-speed airflow into the duct. The exhaust slot facilitates the duct guiding the airflow out of the exhaust slot, allowing the airflow to... A relatively uniform air curtain is blown between the packaging bag and the heat-sealing panel. This helps the packaging bag peel off the heat-sealing panel during heat sealing and also accelerates the cooling and hardening of the heat-sealed portion, facilitating subsequent cutting. The mounting bracket allows for easy and secure connection between the peeling component and the control component, enabling the two air ducts to be fixedly installed on top of the heat-sealing assembly. The mounting bracket also ensures that the air ducts do not obstruct the downward movement of the packaging bag, facilitating heat sealing. This invention blows airflow from both sides of the top after the packaging bag is heat-sealed, helping to peel the bag off the heat-sealing panel and preventing adhesion. It also accelerates the cooling and hardening of the packaging bag, demonstrating high practical value. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5This utility model provides a technical solution: an improved horizontal sealing device for a vertical packaging machine, including a control component 1. The control component 1 facilitates the control of a heat-sealing component 2, enabling the heat-sealing component 2 to heat-seal the packaging bag. The heat-sealing component 2 is located on one side of the control component 1, facilitating the heat-sealing of the packaging bag. A peeling component 3 is located at the top of the heat-sealing component 2, allowing a high-speed airflow to peel the sealed packaging bag off the surface of the heat-sealing panel 23. The control component 1 includes a protective box 11, providing a mounting base and protecting the internal structure. The heat-sealing component 2 includes two moving plates 21, with a heat-sealing panel 23 located on opposite sides of each moving plate 21, facilitating direct contact with the packaging material for heat sealing. The peeling component 3 includes two air ducts 31, with an air inlet 33 at one end, facilitating the removal of air from the packaging material. High-speed airflow is guided into the interior of the air duct 31. Two air ducts 31 are respectively set on the top of the two moving plates 21. An exhaust slit 37 is opened at the bottom of the air duct 31, facing the top edge of the bottom heat-sealing panel 23. The exhaust slit 37 facilitates the airflow from the air duct 31 to blow out from the exhaust slit 37, so that the airflow is blown between the packaging bag and the heat-sealing panel 23 in a relatively uniform air curtain form. When the packaging bag is heat-sealed, it helps to peel the packaging bag off the heat-sealing panel 23. At the same time, it can also accelerate the cooling and hardening of the heat-sealed part of the packaging bag, which is convenient for subsequent cutting. Mounting brackets 32 are fixedly installed at both ends of the two air ducts 31. One end of the mounting bracket 32 ​​is fixedly installed on the top of the protective box 11. The mounting bracket 32 ​​facilitates the fixed connection between the peeling component 3 and the control component 1, so that the two air ducts 31 can be fixedly installed on the top of the heat-sealing component 2. The mounting bracket 32 ​​ensures that the air ducts 31 do not obstruct the downward movement of the packaging bag, which is convenient for the heat-sealing component 2 to heat-seal it.

[0033] Both air inlets 33 are connected to connecting pipes 34, and the two connecting pipes 34 are connected to three-way solenoid valves 35. One side of the three-way solenoid valve 35 has an air source interface 36. The air source interface 36 facilitates connection to an external high-pressure air source. The three-way solenoid valve 35 is used to control the opening and closing of the air path and synchronously introduces the airflow into the two air guide pipes 31 to control the blowing action of the two exhaust slots 37, so that the airflow is blown out when the heat sealing assembly 2 unfolds after completing the heat sealing action.

[0034] The protective box 11 is rotatably connected to threaded rods 13 at both ends, and the movable plate 21 is fixedly installed with threaded sleeves 22 at both ends. The threaded sleeves 22 are threadedly connected to the threaded rods 13, and the thread directions at both ends of the threaded rods 13 are opposite. By having the thread directions at both ends of the threaded rods 13 opposite, it is easy to control the rotation of the threaded rods 13 to move the two movable plates 21 closer or further apart. When they move closer together, they drive the two heat-sealing panels 23 to heat and pressurize the packaging bag to achieve the heat-sealing action.

[0035] Among them, one end of each of the two threaded rods 13 is rotatably connected to a stabilizing bar 14, and the protective box 11 is provided with mounting ears 12 at both ends. The mounting ears 12 facilitate the fixed installation of the device at the bottom of the vertical packaging machine, making it convenient to heat seal the packaging bag. The stabilizing bar 14 helps to improve the installation stability of the two threaded rods 13.

[0036] The protective box 11 has a control motor 15 fixedly installed inside. The output end of the control motor 15 has a first worm gear 16 fixedly installed. The first worm gear 16 is meshed with a first worm wheel 17. The control motor 15 is designed to make it easy for the control motor 15 to work and drive the first worm gear 16 to rotate the first worm wheel 17.

[0037] The first worm gear 17 has a drive shaft 18 fixedly installed in the middle. The drive shaft 18 is rotatably connected to the protective box 11. The drive shaft 18 is designed to facilitate the rotation of the first worm gear 17 to drive the drive shaft 18 to rotate.

[0038] The transmission shaft 18 has a second worm gear 19 fixedly installed at both ends. The second worm gear 19 is meshed with a second worm wheel 110. The second worm wheel 110 is fixedly connected to the threaded rod 13. The setting of the second worm wheel 110 facilitates the rotation of the transmission shaft 18, which causes the second worm gear 19 to drive the second worm wheel 110 to rotate, thereby controlling the two threaded rods 13 to rotate synchronously.

[0039] Among them, the two movable plates 21 have an installation groove 24 on one side opposite to each other. Several ceramic heating elements 25 are fixedly installed inside the installation groove 24. The arrangement of the ceramic heating elements 25 makes it easy for the ceramic heating elements 25 to form a rectangular array and independently control the temperature, avoiding insufficient temperature at both ends of the heat-sealing panel 23 due to rapid heat dissipation and overheating in the middle due to heat accumulation. This achieves a uniform temperature field across the entire heat-sealing panel 23 and improves the heat-sealing effect.

[0040] The ceramic heating element 25 has an intermediate layer 26 fixedly installed on its outer side. One side of the intermediate layer 26 is fixedly connected to the heat-sealing panel 23. The intermediate layer 26 is made of copper, and the heat-sealing panel 23 is made of high-strength mold steel. The copper intermediate layer 26 and the high-strength mold steel facilitate the efficient transfer of heat from the ceramic heating element 25 to the surface of the heat-sealing panel 23, reducing heat loss. The high-strength mold steel has high hardness, wear resistance, and thermal fatigue resistance, making it suitable for repeated heating and cooling cycles. It is used for heat sealing in direct contact with packaging materials, playing a role in preventing sticking and extending service life.

[0041] Specifically, the working principle of the horizontal sealing device of this improved vertical packaging machine is as follows: During use, the mounting ears 12 facilitate the fixed installation of the device at the bottom of the vertical packaging machine, enabling convenient heat sealing of the packaging bags. The stabilizing strip 14 improves the installation stability of the two threaded rods 13. The control motor 15 allows the motor to drive the first worm gear 16 to rotate the first worm wheel 17. The transmission shaft 18 allows the first worm wheel 17 to rotate, driving the transmission shaft 18. The second worm wheel 110 allows the rotation of the transmission shaft 18 to drive the second worm gear 19 to rotate the second worm wheel 110, thereby controlling the two threaded rods 13. The synchronous rotation, with opposite thread directions at both ends of the threaded rod 13, allows the rotation of the threaded rod 13 to control the two moving plates 21 to move closer or further apart. When they move closer, they drive the two heat-sealing panels 23 to heat and pressurize the packaging bag, achieving the heat-sealing action. The ceramic heating elements 25 are arranged in a rectangular array and independently temperature-controlled, preventing insufficient temperature at both ends of the heat-sealing panel 23 due to rapid heat dissipation and overheating in the middle due to heat accumulation. This ensures a uniform temperature field across the entire heat-sealing panel 23, improving the heat-sealing effect. The intermediate layer 26 is made of copper, while the heat-sealing panel 23 is made of high-strength mold steel, facilitating the bonding of the ceramic heating elements within the high thermal conductivity copper intermediate layer 26. The ceramic heating element 25 efficiently transfers heat to the surface of the heat-sealing panel 23, reducing heat loss. High-strength mold steel possesses high hardness, wear resistance, and resistance to thermal fatigue, making it suitable for repeated heating and cooling cycles. It is used for heat sealing in direct contact with packaging materials, providing anti-sticking properties and extending service life. The mounting bracket 32 ​​facilitates the fixed connection between the peeling assembly 3 and the control assembly 1, allowing the two air ducts 31 to be fixedly installed on top of the heat-sealing assembly 2. The mounting bracket 32 ​​also ensures that the air ducts 31 do not obstruct the downward movement of the packaging bag, facilitating heat sealing by the heat-sealing assembly 2. The air source interface 36 allows for easy connection to an external high-pressure air source. (Three-way electromagnetic...) Valve 35 is used to control the opening and closing of the air passage and synchronously introduce airflow into the two air guide pipes 31 to control the blowing action of the two exhaust slots 37. When the heat sealing assembly 2 unfolds after completing the heat sealing action, it blows out airflow. The setting of the air inlet 33 facilitates the guidance of high-speed airflow into the air guide pipe 31. The setting of the exhaust slot 37 facilitates the air guide pipe 31 to guide the airflow out of the exhaust slot 37, so that the airflow is blown into the space between the packaging bag and the heat sealing panel 23 in a relatively uniform air curtain form. When the packaging bag is heat sealed, it helps the packaging bag to peel off the heat sealing panel 23. At the same time, it can also accelerate the cooling and hardening of the heat-sealed part of the packaging bag, which is convenient for subsequent cutting.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
