[0002] Bag-shaped tablets refer to a form of medicine in which tablets are packaged and sold in bags. During the production process of tablets, outer packaging equipment is usually used to package the tablets. The tablet outer packaging equipment is a machine for automatically loading tablets into packaging bags or boxes. It usually includes functions such as automatic feeding, packaging, sealing, and discharging, which can greatly improve the efficiency and accuracy of medicine packaging.

[0003] Currently, during the process of packaging tablets using outer packaging equipment, it is necessary to convey the quantitatively measured tablets into the packaging bag, then squeeze and heat-seal the packaging bag containing the tablets through a heat-sealing component, and then cut the heat-sealed packaging bag through a cutting knife. However, in the actual production process, since most packaging bags contain plastic components, when the packaging bag is heat-sealed and squeezed, the plastic is prone to decomposition at high temperatures, forming air with peculiar smells, resulting in environmental pollution. At the same time, the air with peculiar smells may also enter the packaging bag during the heat-sealing process, causing the tablets in the packaging bag to be contaminated, thus affecting the production safety of the tablets.

[0027] Referring to Figures 1-7 , an embodiment of the present utility model provides a bag-shaped tablet outer packaging machine, which includes a packaging machine body 1 equipped with a cutting device 2, and further includes: a frame body 3 with openings on both the upper and lower sides, fixedly connected to the packaging machine body 1. Among them, two heat-sealing plates 4 are installed on the frame body 3, and a reciprocating part for driving the two heat-sealing plates 4 to move towards and away from each other is provided on the frame body 3. One side of the frame body 3 is communicated with a housing 5; a filter element 6 is installed in the housing 5. Among them, the filter element 6 is provided with activated carbon, which can preferably filter the air containing peculiar smell. A fan 7 is installed inside the housing 5, and a driving part for driving the fan 7 to rotate is provided on the housing 5. The air suction end of the fan 7 faces the filter element 6, and the air exhaust end of the fan 7 faces the air exhaust port of the housing 5.

[0028] Specifically, during use, through the cooperation of the reciprocating part and the driving part, the two heat-sealing plates 4 can be driven to move reciprocally towards and away from each other, so as to heat-seal the continuously conveyed packaging bags containing tablets. And it can also synchronously drive the fan 7 to rotate, so that the air containing peculiar smell formed during the heat-sealing process of the packaging bags is sucked into the housing 5, and the peculiar smell molecules in the air are adsorbed by the filter element 6, thereby realizing the purification of the air, preventing the air containing peculiar smell from floating around and polluting the environment and the tablets, and thus improving the production safety of the tablets.

[0029] The reciprocating part includes: a first motor 41, fixedly installed on the outer wall of the frame body 3; among them, a reciprocating lead screw 42 is rotatably connected to the frame body 3, and one end of the reciprocating lead screw 42 is fixedly connected to the output end of the first motor 41.

[0030] Specifically, during use, by starting the first motor 41, the output end of the first motor 41 drives the reciprocating lead screw 42 to rotate. Under the action of the opposite threads, the moving plate 43 drives the two heat-sealing plates 4 to perform reciprocating approaching and separating movements, so as to be able to perform heat-sealing processing on the continuously conveyed packaging bags containing tablets.

[0031] The driving part includes: a rotating rod 71 rotatably connected to the housing 5; wherein, pulley 72 connected by a belt is fixedly connected to the surfaces of both the rotating rod 71 and the reciprocating lead screw 42; the rotating shaft of the fan 7 is rotatably connected to the housing 5 through a support plate, and bevel gears 73 that mesh with each other are fixedly connected to both the rotating shaft of the fan 7 and the rotating rod 71.

[0032] Specifically, during use, when the reciprocating lead screw 42 rotates, it drives the two pulleys 72 and the rotating rod 71 to rotate, and at the same time drives the bevel gears 73 and the fan 7 to rotate. By the rotation of the fan 7, negative pressure is generated inside the housing 5. Under the action of the negative pressure, the air containing peculiar smell formed during the heat-sealing process of the packaging bag can be quickly sucked into the housing 5.

[0033] A second motor 81 is fixedly installed on the outer wall of the housing 5, and a screw rod 82 is rotatably connected to the housing 5.

An inspection opening 10 is penetrated and opened at the top of the housing 5, and an inspection cover plate 11 is detachably installed in the inspection opening 10.

[0038] Specifically, through the settings of the mounting bracket 9, the inspection opening 10, and the inspection cover plate 11, it is convenient for the staff to take out the filter element 6 from the housing 5 for replacement and maintenance.

[0039] The specific working process is as follows: During the use of this bag-shaped tablet outer packaging machine, by starting the first motor 41, the output end of the first motor 41 drives the reciprocating lead screw 42 to rotate. Under the action of the opposite threads, the moving plate 43 drives the two heat-sealing plates 4 to perform reciprocating approaching and separating movements, so as to be able to perform heat-sealing processing on the continuously conveyed packaging bags containing tablets. The heat-sealed packaging bags will be conveyed downward and cut by the cutting device 2;

[0040] And during the heat-sealing process, when the reciprocating lead screw 42 rotates, it drives the two belt pulleys 72 and the rotating rod 71 to rotate, and at the same time drives the bevel gear 73 and the fan 7 to rotate. By the rotation of the fan 7, negative pressure is generated inside the housing 5. Under the action of the negative pressure, the air containing peculiar smell formed during the heat-sealing process of the packaging bag is inhaled into the housing 5, and the peculiar smell molecules in the air are adsorbed by the filter element 6, so as to realize the purification of the air. Then the purified air is discharged to the outside through the fan 7, preventing the air containing peculiar smell from floating around and polluting the environment and the tablets, thereby improving the production safety of the tablets.

[0041] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
