Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical packaging, and particularly relates to a medicine box-shaped tablet outer packaging machine. Background Art

[0002] A medicine box-shaped tablet refers to a form in which tablets are arranged in a medicine box during packaging. Medicine box-shaped tablets are usually used to facilitate patients' taking and convenient carrying. Each tablet is usually placed in an independent grid or compartment to ensure that the tablets will not be confused or damaged with each other. Each medicine box usually comes with a label or instruction manual indicating information such as the name of the drug, dosage, taking method, etc., to facilitate patients to take the medicine correctly. The design of medicine box-shaped tablets is usually quite innovative, and medicine box forms with specific functions can be designed according to different needs, such as waterproof, moisture-proof, long-acting, etc. Medicine box-shaped tablets are usually quite light and easy for patients to carry, facilitating daily taking and use during travel. Each medicine box usually contains a certain number of tablets, facilitating patients to take the medicine as needed according to the doctor's advice and reducing the possibility of taking medicine errors.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0024] Embodiment:

[0025] Refer to Figures 1-4 , a medicine box-shaped tablet outer packaging machine, including a machine body 1. A plurality of rotatable rollers are further provided on the machine body 1, and the rollers can be driven to rotate by a motor or a motor. A conveyor belt is formed between the plurality of rollers, and a transparent plastic film is placed on the conveyor belt. Grooves are formed on the transparent plastic film, and the grooves are arranged at equal intervals in the shape of a medicine box. After placing tablets in the grooves, a film sealing operation can be performed, and then it is cut into the shape of a medicine box by a cutting device, thereby completing the packaging of the medicine box-shaped medicine.

[0026] In addition, a connecting seat is fixedly connected to the machine body 1, and a cleaning cylinder 2 is rotatably connected to the connecting seat through a hollow tube. An air jet hole 201 is formed in the cleaning cylinder 2, and the jet end of the air jet hole 201 faces the roller. A contact wheel 3 is fixedly connected to the cleaning cylinder 2. Protrusions made of rubber or silica gel are further provided on the outer part of the contact wheel 3, and the contact wheel 3 is attached to the film surface.

[0027] When the cleaning cylinder 2 rotates, the protrusions on the contact wheel 3 will be attached to the film surface, and the protrusions made of rubber or silica gel can increase the friction with the film surface, so that when the cleaning cylinder 2 rotates, it can also perform a limiting movement on the film surface to prevent the film from shaking during the movement.

[0028] A pressure increasing disc 4 is also fixedly connected to the connecting seat, and a hollow tube is fixedly connected to the cleaning cylinder 2. The hollow tube is rotatably connected to the connecting seat, and one end of the hollow tube is rotatably connected to the pressure increasing disc 4, and the hollow tube is communicated with the cavity of the pressure increasing disc 4.

[0029] Please refer to Figure 2As shown in the figure, an intake pipe can be provided on the pressure increasing disc 4. Air can be supplied into the intake pipe through an air pump or a negative pressure pump, and then transported into the cavity of the pressure increasing disc 4. Then, the air is transported into the cleaning cylinder 2 through a hollow pipe. At this time, the cleaning cylinder 2 will jet air through the air jet holes 201, and then spray the gas into the groove to blow the dust particles in the groove. Higher air flow velocity and pressure can be generated through the air jet holes 201. During the movement of the film, the air jet holes 201 will jet air into the groove, which can effectively blow out the dust particles in the groove, keep the groove clean, reduce the dust particles in the groove during subsequent film sealing, and improve the cleanliness of the packaged tablets during packaging.

[0030] In addition, referring to Figure 3 and Figure 4 a cleaning box 5 is fixedly installed on the machine body 1. A reciprocating lead screw 501 is rotatably connected in the cleaning box 5, and a cleaning block 6 is threadedly connected to the reciprocating lead screw 501. Moreover, a brush 601 is fixedly connected to the cleaning block 6, and the contact end of the brush 601 abuts against the surface of the film.

[0031] Two groups of symmetric negative pressure suction plates 7 are fixedly connected to the inner wall of the cleaning box 5. Negative pressure suction holes 701 are provided on the negative pressure suction plates 7, and the negative pressure suction holes 701 cooperate with the brush 601. The two sides of the cleaning block 6 are respectively attached to the outer wall of the negative pressure suction plate 7, which can prevent the cleaning block 6 from shaking. The negative pressure suction plate 7 is connected to the input end of the negative pressure pump through a negative pressure pipe, and a collection box is provided on the negative pressure pipe. A filter screen is installed in the collection box to intercept and collect dust particles.

[0032] A driving machine is also fixedly connected to the connecting seat. The other end of the cleaning cylinder 2 is fixedly connected to the output end of the driving machine through a connecting shaft. An auxiliary gear is also fixedly connected to the reciprocating lead screw 501, and a main gear is fixedly connected to the end of the cleaning cylinder 2 away from the pressure increasing disc 4. The main gear can be fixedly connected to the connecting shaft, and then the main gear is meshed with the auxiliary gear. When the main gear rotates one week, the auxiliary gear rotates two weeks.

[0033] At this time, when the driving machine drives the connecting shaft to rotate one week, the main gear rotates one week. At this time, the auxiliary gear will drive the reciprocating lead screw 501 to rotate two weeks, so that the reciprocating lead screw 501 drives the cleaning block 6 to move back and forth twice, so that the brush 601 can clean the groove. At this time, the negative pressure suction plate 7 is started, and the negative pressure suction holes 701 will adsorb the dust particles brushed by the brush 601, further reducing the dust particles in the groove. After sealing the transparent plastic film, it can prevent the remaining dust particles inside from contaminating the tablets inside and improve the qualification rate of finished product quality inspection.

[0034] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
