Description
Technical Field
[0001] This application relates to the technical field of packaging machines, and in particular to a fully automatic packaging machine. Background Technology
[0002] Packaging machines are mechanical devices used to automatically complete the product packaging process. They are widely used in many industries such as food, beverage, pharmaceutical, chemical, and electronics. They can improve production efficiency, reduce labor costs, and ensure the consistency and quality of packaging. When packaging items, existing packaging machines need to first lay a base film on the packaging table, then place the items on the packaging table, cover the items with a packaging film, and finally seal and cut them.
[0003] The existing announcement number CN205366199U, entitled "A New Type of Packaging Machine," includes a frame and an input device and a suction gripping device mounted on the frame along the production line. This new packaging machine, through a pushing device, can directly push cartons of cigarettes from the input device into the output station, while the suction gripping device can selectively pick up irregularly shaped cigarettes as needed. This satisfies both irregularly shaped and regular cigarette packaging needs, thereby increasing speed and efficiency during regular cigarette packaging. A baffle bar is included, which can reduce the number of cartons of cigarettes that can be pushed by its translation. When packaging regular cigarettes, a specified quantity can be pushed using the translation of the baffle bar. The same applies to irregularly shaped cigarettes; as long as the width data is available, a set quantity of cigarettes can be pushed, thus improving work efficiency. Furthermore, a diversion device is included, allowing two stations to operate simultaneously, which further improves the efficiency of cigarette packaging.
[0004] Regarding the aforementioned technologies, the inventors discovered that the packaging machines are limited by fixed mechanical structures and dimensional parameters, and can only adapt to packaging bags of specific specifications or size ranges. When it is necessary to change to packaging bags of different sizes, it is often necessary to stop the machine to adjust mechanical parts or replace the entire set of molds, which is not only time-consuming and labor-intensive, but also increases production costs and operational complexity. Utility Model Content
[0005] In order to overcome the fact that existing packaging machines can only adapt to packaging bags of specific specifications or size ranges, and that when it is necessary to change to packaging bags of different sizes, it is often necessary to stop the machine to adjust mechanical parts or replace the entire set of molds, which is not only time-consuming and labor-intensive, but also increases production costs and operational complexity, this application provides a fully automatic packaging machine.
[0006] The fully automatic packaging machine provided in this application adopts the following technical solution: An automatic packaging machine includes a machine casing, a first sealing component, and a second sealing component. The first sealing component is vertically arranged on the front side of the top surface of the machine casing, and the second sealing component is vertically arranged on the rear side of the top surface of the machine casing. The second sealing component includes a hole frame, which is vertically fixed to the rear side of the top surface of the machine casing. A film frame is horizontally slidably assembled on the hole frame. A second movable frame is vertically fixed on the front vertical end face of the film frame, and a second lifting slide frame is vertically slidably assembled on the second movable frame. A U-shaped hot-cutting blade is horizontally fixed on the bottom surface of the second lifting slide frame. The first sealing component includes a fixing frame, which is vertically fixed to the front surface of the machine casing. A first movable frame is vertically fixed on the rear vertical end face of the fixing frame, and a first lifting slide frame is vertically slidably assembled on the first movable frame. A hot-cutting blade is horizontally fixed on the bottom surface of the first lifting slide frame.
[0007] By adopting the above technical solution, during use, a suitable packaging film roll is selected according to the specific size of the product to be packaged. These rolls are then assembled on one side of the film frame. Next, the film frame on the second sealing component slides laterally, causing the U-shaped hot-cutting blade to adapt to the lateral length requirements of the packaged product. The bottom packaging film of one side of the film roll is then wrapped around the other side of the film frame, and simultaneously the top packaging film of the same roll is wrapped around the other side. The product to be packaged is placed between the upper and lower packaging films. During packaging, the first lifting slide frame in the first moving frame of the first sealing component moves vertically downwards, causing the hot-cutting blade to move downwards, thus packaging the product. The front side is heat-sealed. The second lifting slide frame in the second moving frame of the second sealing component moves vertically downward, driving the U-shaped heat-sealing frame blade downward to heat-seal the sides and back of the product to be packaged. This completes the sealing and packaging of the product. After the packaged product is removed, the packaging film roll on the film holder is started to rotate, and the packaging film is switched to package the next product. Thus, the packaging machine switches the heat-sealing length of the second sealing component according to the product packaging size, which can adapt to the packaging needs of packaging bags of different specifications or size ranges. There is no need to stop the machine to adjust mechanical parts or replace the entire set of molds, which reduces time and labor, and lowers production costs and operational complexity.
[0008] Optionally, a first sealing hydraulic rod is vertically fixed on the top surface of the fixing frame, and the output end of the first sealing hydraulic rod is fixed on the top surface of the first lifting slide frame.
[0009] By adopting the above technical solution, the first sealing hydraulic rod is activated to extend and push the first lifting slide frame to move vertically downward in the first moving frame, thereby driving the hot cutting blade to move downward and perform hot cutting and sealing on the front side of the product to be packaged.
[0010] Optionally, two film winding screws are horizontally rotatably connected to both sides of the film frame, and each film winding screw is threaded with a screw cap.
[0011] By adopting the above technical solution, the two film-winding screws that are horizontally rotatably connected on both sides of the film frame are used to mount and assemble packaging film rolls. At the same time, in order to meet the needs of wrapping packaging film of different lengths, the rotating screw cap moves laterally on the film-winding screw to install and clamp packaging film rolls of different sizes.
[0012] Optionally, a motor is horizontally fixed on one side of the film frame, and the motor output end is fixed to the end of the film winding screw.
[0013] By adopting the above technical solution, in order to continuously process the packaging film, the motor is started to drive the film winding screw to rotate, driving the packaging film roll to move on both sides of the film frame to continuously process the packaging film.
[0014] Optionally, a sliding rod is horizontally fixed on the rear vertical end face of the membrane frame, and the sliding rod of the membrane frame slides through the hole frame.
[0015] By adopting the above technical solution, the slide rod fixed on the rear side of the film frame slides through the hole frame and guides the film frame to slide laterally on the hole frame, which makes it easy to control the sealing and cutting length of the U-shaped hot cutting frame knife according to the specific size of the product to be packaged.
[0016] Optionally, a telescopic hydraulic rod is horizontally fixed on the top surface of the diaphragm frame, and the output end of the telescopic hydraulic rod is fixed on the diaphragm frame.
[0017] By adopting the above technical solution, according to the specific size of the product to be packaged, the slide rod fixed on the back of the film frame slides through the hole frame, and the transverse sliding guide film frame slides transversely on the hole frame, controlling the sealing and cutting length of the U-shaped hot cutting frame knife.
[0018] Optionally, a second sealing hydraulic rod is vertically fixed on the top surface of the membrane frame, and the output end of the second sealing hydraulic rod is fixed on the top surface of the second lifting slide frame.
[0019] By adopting the above technical solution, the second sealing hydraulic rod is activated to drive the second lifting slide frame in the second moving frame of the second sealing component to move vertically downward, which in turn drives the U-shaped hot cutting frame knife to move downward to perform hot cutting and sealing treatment on both sides and the back side of the product to be packaged, thus completing the sealing and packaging of the product to be packaged.
[0020] Optionally, a sealing and cutting platform is horizontally fixed in the middle of the top surface of the chassis.
[0021] By adopting the above technical solution, the sealing and cutting table fixed on the top surface of the chassis is used to cooperate with the first sealing component and the second sealing component to seal and heat-cut the product packaging film.
[0022] In summary, this application includes at least one of the following beneficial technical effects: During use, select the appropriate packaging film roll according to the specific dimensions of the product to be packaged, and assemble them on one side of the film frame. Then, start the horizontal sliding motion of the film frame on the middle hole frame of the second sealing component, which drives the U-shaped hot cutting frame knife to meet the horizontal length requirements of the packaged product. Then, wrap the bottom packaging film of one side of the film roll around the other side of the film frame, and at the same time, wrap the top packaging film of one side of the film roll around the other side of the film frame. Place the product to be packaged between the upper and lower packaging films. During packaging, start the first lifting slide frame on the first moving frame of the first sealing component to move vertically downward, which drives the hot cutting knife to move downward and perform hot cutting on the front side of the product to be packaged. The sealing process begins with the second lifting slide frame in the second moving frame of the second sealing component moving vertically downwards. This causes the U-shaped hot-cutting frame blade to move downwards, performing hot-cutting and sealing on both sides and the back of the product to be packaged. This completes the sealing and packaging of the product. After the packaged product is removed, the packaging film roll on the film holder is rotated to switch the packaging film for the next product. Thus, the packaging machine switches the hot-cutting and sealing length of the second sealing component according to the product packaging size, adapting to the packaging needs of bags of different specifications or sizes. This eliminates the need to stop the machine to adjust mechanical parts or replace the entire set of molds, reducing time and labor costs, and lowering production costs and operational complexity.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.
[0026] This application discloses a fully automatic packaging machine. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 An automatic packaging machine includes a machine housing 1, a first sealing component 2, and a second sealing component 3. The first sealing component 2 is vertically arranged on the front side of the top surface of the machine housing 1, and the second sealing component 3 is vertically arranged on the rear side of the top surface of the machine housing 1. The second sealing component 3 includes a hole frame 31, which is vertically fixed to the rear side of the top surface of the machine housing 1. A film frame 33 is horizontally slidably assembled on the hole frame 31. A second movable frame 34 is vertically fixed on the front vertical end face of the film frame 33. A second lifting slide frame 35 is vertically slidably assembled. A U-shaped hot cutting frame knife 36 is horizontally fixed on the bottom surface of the second lifting slide frame 35. The first sealing component 2 includes a fixing frame 21, which is vertically fixed on the front end face of the chassis 1. A first moving frame 22 is vertically fixed on the rear vertical end face of the fixing frame 21. A first lifting slide frame 23 is vertically slidably assembled on the first moving frame 22. A hot cutting knife 25 is horizontally fixed on the bottom surface of the first lifting slide frame 23.
[0027] By adopting the above technical solution, during use, a suitable packaging film roll is selected according to the specific size of the product to be packaged, and the packaging film rolls are respectively installed on one side of the film frame 33. Then, the film frame 33 on the hole frame 31 of the second sealing component 3 is moved horizontally and slid, driving the U-shaped hot cutting frame blade 36 to meet the horizontal length requirements of the packaged product. Then, the bottom packaging film of the packaging film roll on one side of the film frame 33 is wrapped around the other side of the film frame 33, and at the same time, the top packaging film of the packaging film roll on one side of the film frame 33 is wrapped around the other side of the film frame 33. The product to be packaged is placed between the upper and lower packaging films. During packaging, the first lifting sliding frame 23 in the first moving frame 22 on the first sealing component 2 is moved vertically downward, driving the hot cutting blade 25 downward. The front side of the product to be packaged is heat-sealed. The second lifting slide frame 35 in the second moving frame 34 of the second sealing component 3 moves vertically downward, driving the U-shaped heat-sealing frame blade 36 to move downward to heat-seal the sides and back of the product to be packaged. After the product to be packaged is sealed, the packaged product is removed. Then, the packaging film roll on the film holder 33 is started to rotate, and the packaging film is switched to package the next product. Thus, the packaging machine switches the heat-sealing length of the second sealing component 3 according to the product packaging size, which can adapt to the packaging needs of packaging bags of different specifications or size ranges. There is no need to stop the machine to adjust mechanical parts or replace the entire set of molds, which reduces time and labor, and lowers production costs and operational complexity.
[0028] Reference Figure 4A first sealing hydraulic rod 24 is vertically fixed on the top surface of the fixed frame 21, and the output end of the first sealing hydraulic rod 24 is fixed on the top surface of the first lifting slide frame 23. When the first sealing hydraulic rod 24 is activated, it extends and pushes the first lifting slide frame 23 to move vertically downward in the first moving frame 22, thereby driving the hot cutting blade 25 to move downward and perform hot cutting and sealing on the front side of the product to be packaged.
[0029] Reference Figure 3 Two film-winding screws 38 are horizontally rotatably connected to both sides of the film holder 33, and each screw 38 is threaded with a cap 39. These two screws are used to mount and assemble packaging film rolls. To accommodate different lengths of packaging film, the caps 39 are rotated and moved laterally on the screws 38 to clamp and assemble packaging film rolls of different sizes. A motor 331 is horizontally fixed to one side of the film holder 33, and its output is fixed to the end of one of the screws 38. To continuously package the film, the motor 331 is started, driving the screws 38 to rotate and unwinding the packaging film rolls onto both sides of the film holder 33 for continuous packaging.
[0030] Reference Figure 2 and Figure 3 Each of the vertical ends of the rear side of the film holder 33 is horizontally fixed with a sliding rod, and the sliding rod of the film holder 33 is slidably assembled through the hole frame 31. The sliding rod fixed to the rear side of the film holder 33 is slidably assembled through the hole frame 31, and the transverse sliding guides the film holder 33 to slide laterally on the hole frame 31, which facilitates the control of the sealing and cutting length of the U-shaped hot cutting frame knife 36 according to the specific size of the product to be packaged.
[0031] Reference Figure 3 A horizontally fixed extension hydraulic rod 32 is mounted on the top surface of the perforated frame 31, and the output end of the extension hydraulic rod 32 is fixed to the film frame 33. According to the specific dimensions of the product to be packaged, a sliding rod fixed to the rear side of the film frame 33 slides through the perforated frame 31, guiding the film frame 33 to slide laterally on the perforated frame 31, controlling the sealing and cutting length of the U-shaped hot-cutting frame knife 36. A second sealing hydraulic rod 37 is vertically fixed on the top surface of the film frame 33, and the output end of the second sealing hydraulic rod 37 is fixed to the top surface of the second lifting slide frame 35. Activating the second sealing hydraulic rod 37 causes the second lifting slide frame 35 in the second moving frame 34 of the second sealing component 3 to move vertically downwards, causing the U-shaped hot-cutting frame knife 36 to move downwards to perform hot-cut sealing on both sides and the rear side of the product to be packaged, thus completing the sealing and packaging of the product.
[0032] Reference Figure 5 A sealing and cutting table 11 is horizontally fixed in the middle of the top surface of the casing 1. The sealing and cutting table 11 fixed on the top surface of the casing 1 is used to cooperate with the first sealing component 2 and the second sealing component 3 to seal and heat-cut the product packaging film.
[0033] The implementation principle of a fully automatic packaging machine according to this application embodiment is as follows: During use, a suitable packaging film roll is selected based on the specific dimensions of the product to be packaged. These rolls are then assembled on one side of the film frame 33. The film frame 33 on the hole frame 31 of the second sealing component 3 slides laterally, driving the U-shaped hot-cutting frame knife 36 to meet the lateral length requirements of the packaged product. The bottom packaging film of one side of the film roll is then wrapped around the other side of the film frame 33, and simultaneously, the top packaging film of one side of the film roll is wrapped around the other side of the film frame 33. The product to be packaged is placed between the upper and lower packaging films. During packaging, the first sealing hydraulic rod 24 is activated to extend and push the first lifting slide frame 23 vertically within the first moving frame 22. The machine moves downwards, causing the hot-cutting blade 25 to move down and perform a hot-cutting seal on the front side of the product to be packaged. The second sealing hydraulic rod 37 is then activated, causing the second lifting slide frame 35 in the second moving frame 34 of the second sealing component 3 to move vertically downwards. This causes the U-shaped hot-cutting frame blade 36 to move down and perform hot-cutting seals on the sides and back of the product to be packaged, completing the sealing process. After the packaged product is removed, the packaging film roll on the film holder 33 is rotated to switch packaging film for the next product. Thus, the packaging machine can switch the hot-cutting seal length of the second sealing component 3 according to the product packaging size, adapting to the packaging needs of different specifications or size ranges.
[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
