Abstract
Description
Technical Field
[0001] The utility model relates to a packaging machine, in particular to a pillow packaging machine and a pillow bag transverse sealing device of the pillow packaging machine. Background Art
[0002] A pillow packaging machine is a device that uses a film to package individual materials such as medicines, foods, and hardware. It generally includes a grid conveyor, a film former, and a pillow bag transverse sealing device. The grid conveyor is used to convey the packaged material forward; the film former is used to shape the film, and the film wraps the packaged material; the pillow bag transverse sealing device is used to cut the packaged materials wrapped in the film one by one, and heat-seal the film cuts at the same time, thereby forming pillow bags. The transverse sealing device of a traditional pillow packaging machine is fixed. When the machine stops, the upper and lower sealing knives of the transverse sealing device need to be opened (because the upper and lower sealing knives will heat up), and the upper and lower sealing knives must be positioned between two adjacent packaged materials. In this way, when the machine is turned on, the upper and lower sealing knives can move relative to each other to cut between two adjacent packaged materials. That is to say, when the machine is stopped, the position of the packaged materials in the pillow bag transverse sealing device is determined, for example Figure 1 In the above figure, there are 8 packages between the discharge end of the grid conveyor and the pillow bag transverse sealing device; the first package from the left is also just in the film former, which is an ideal state. However, when the length of the packaged material changes, the grid partition of the grid conveyor also needs to be adjusted, such as Figure 1 In the next figure, if the position of the pillow bag transverse sealing device remains unchanged, then when the machine is stopped, the packaged material remaining on the film former mouth will be wrapped in different parts of the film due to the different front and rear positions of the grid partition. When the film is wrapped too little, the position of the packaged material will slide relative to the film when the machine is started (after the packaged material enters the film former, it is driven forward by the friction between it and the film), resulting in uncertain position of the packaged material in the film (that is, the distance between two adjacent packaged materials is not equidistant). When it continues to move forward to the transverse sealing station, the material will be cut by the transverse sealing knife, and finally the material will be damaged or the cutter will be lost. Summary of the Invention
[0003] In view of the deficiencies in the existing technology, the utility model innovatively provides a pillow bag transverse sealing device that can realize position movement and adjustment, and a new pillow bag machine that solves the problem of stable transportation of materials of different specifications through the movable pillow bag transverse sealing device.

[0013] like Figure 1 and Figure 2As shown, this new pillow bagging machine includes a grid conveyor 1, a film former 2, and a transverse sealing device 3 for pillow bags. The transverse sealing device 3 is located in front of the grid conveyor 1, and the film former 2 is located at the discharge end of the grid conveyor 1. The operating principle of this new pillow bagging machine is as follows: The packaged objects 40 (such as blister tablets) are sequentially fed onto the grid conveyor via a feeder or a robot. The film is pulled forward by a film traction wheel 5. Through the film former 2, the film is transformed from a flat surface into a semicircular cylindrical state. At the discharge end of the grid conveyor 1, the packaged objects 40 are sequentially fed into the cylindrical film formed by the film former 2. The cylindrical film, wrapped around the packaged objects 40, is sealed by a flat center sealing device 6 to form a complete cylindrical shape. The cylindrical film, wrapped around the packaged objects 40, then enters the transverse sealing device 3 for pillow bags. The transverse sealing device 3 cuts each packaged object 40 and the film at equal distances and seals the two ends, ultimately forming a complete pillow bag 4.
[0014] like Figure 2 As shown, the grid conveyor device 1 includes a feed power source, a feed chain 11, a feed sprocket 12, and a plurality of grid baffles 10. The feed chain 11 is wound around the feed sprocket 12, and the plurality of grid baffles 10 are equidistantly connected to the feed chain 11. The feed power source is in driving connection with the feed sprocket 12. Driven by the feed power source, the feed sprocket 12 drives the feed chain 11 to rotate, thereby causing the grid baffles 10 to push the packaged objects 40 forward. When the packaged objects 40 are pushed into the film former 2, the cylindrical film carries the packaged objects 40 forward and finally enters the pillow bag transverse sealing device for cutting and end sealing.
[0015] like Figure 3 and Figure 4 As shown, this pillow bag transverse sealing device includes an upper sealing knife 34, a lower sealing knife 35, a front belt conveying mechanism 37, a rear belt conveying mechanism 36, and a transverse sealing knife frame 30. The upper sealing knife 34, the lower sealing knife 35, the front belt conveying mechanism 37, and the rear belt conveying mechanism 36 are all mounted on the transverse sealing knife frame 30; the front belt conveying mechanism 37 and the rear belt conveying mechanism 36 can move relative to each other. When a gap is formed, the upper sealing knife 34 and the lower sealing knife 35 move relative to each other and cut the film, while heat-sealing the end of the film (this is the prior art); and in order to be able to adjust the front and rear position of the pillow bag transverse sealing device, a base 32 is provided below the transverse sealing knife frame 30, as shown in FIG. Figure 4 As shown, the base 32 is provided with a linear slide 320 extending in the front-to-back direction. A movable slide 31 is slidably mounted on the linear slide 320, and the transverse sealing blade holder 30 is mounted on the movable slide 31. Thus, simply moving the movable slide 31 drives the transverse sealing blade holder 30 to move, thereby driving the upper sealing blade 34, the lower sealing blade 35, the front belt conveyor mechanism 37, and the rear belt conveyor mechanism 36 to move forward and backward.
[0016] The advantages of the pillow bag transverse sealing device being able to adjust its front and rear position are as follows: When the machine is shut down, the feed power source only needs to control the grid partition 10 closest to the film former 2 to remain at the film former 2's inlet. This ensures that this grid partition 10 pushes the packaged items 40 precisely into the film former 2 (referred to as the optimal feed position), allowing the cylindrical film to completely wrap around the packaged items 40. The front and rear position of the pillow bag transverse sealing device 3 is then adjusted to align the upper sealing blade 34 and the lower sealing blade 35 between two adjacent packages 40. This allows the packaged items 40 within the film former 2 to be smoothly carried by the film when the machine is restarted, ensuring accurate cutting by the pillow bag transverse sealing device. In other words, when the machine is shut down, the feed position at the film former 2 is fixed, and only the position of the pillow bag transverse sealing device 3 needs to be adjusted. This ensures that packages 40 of varying sizes can be placed in the optimal feed position, ensuring accurate cutting by the pillow bag transverse sealing device.
[0017] In order to facilitate the adjustment of the movement of the movable slide 31, as shown in FIG. Figure 4 As shown, a rotatable adjusting screw 33 is mounted on the base 32, and an adjusting screw sleeve 39 is connected to the movable slide 31. The adjusting screw sleeve 39 is threadedly connected to the adjusting screw 33. In this way, as long as the adjusting screw 33 is rotated, the movable slide 31 can be driven to slide on the linear slide rail 320.
[0018] To more stably drive the movement of the movable slide 31, two parallel adjustment screws 33 are mounted on the base 32. Each adjustment screw 33 is connected to a passive bevel gear 330. A rotatable transmission shaft 38 is mounted on the base 32. Two active bevel gears 380 are mounted on the transmission shaft 38. Each active bevel gear 380 meshes with a corresponding passive bevel gear 330. Thus, by rotating the transmission shaft 38, the two active bevel gears 380 can be driven to rotate the two passive bevel gears 330. This allows the two adjustment screws 33 to rotate synchronously, thus ensuring more stable movement of the movable slide 31.
