Description

Technical Field

[0001] The present invention relates to the field of instant film agent packaging equipment, and particularly to an instant film agent packaging machine. Background Art

[0002] Oral Dissolving Film (ODF) pharmaceutical preparations are the latest generation of oral pharmaceutical preparation products in the world today. The size and thickness of a medicine film are similar to those of an ordinary stamp. When taking medicine, place the medicine film on the surface or under the tongue, and the whole medicine film will completely dissolve in saliva within 10 to 60 seconds. There is no need to drink water to quickly complete the medicine-taking process. Oral Dissolving Film perfectly combines the advantages of traditional solid dosage forms tablets / capsules (accurate dosage) and liquid dosage forms syrup / oral liquid (easy to take and rapid absorption), and solves the problems of difficult medicine-taking and inaccurate dosage for children, the elderly and special populations.

[0003] Most drugs are made into oral dissolving films. Actually, the material is dried into a film by a film-making machine and then adhered to the bottom film. When packaging is required, the bottom film and the material film need to be separated, and then the material film is packaged with packaging paper. Generally, two layers of thin films are heat-sealed to seal the oral dissolving film and then cut into pieces of packaged products;

[0004] When packaging oral dissolving films by an oral dissolving film packaging machine, the whole strip of oral dissolving films needs to be sliced and spaced apart for subsequent heat-sealing packaging at the packaging station. In the prior art, the spacing of oral dissolving films is adjusted by a variable-spacing module to adjust the left-right spacing between the sliced oral dissolving films. However, the variable-spacing module not only has a high cost but also has low efficiency by adjusting the spacing one by one through the variable-spacing module. It is necessary to improve this;

[0005] In addition, when producing, the bottom film with the material film, that is, the raw material film and the packaging film, have the problem of exhaustion during packaging because the film roll is not of infinite length. When the previous film roll is exhausted, another film roll needs to be spliced at the tail of the previous film roll. Generally, adhesive tape is used for splicing, and then the splicing part is manually cut. However, manual cutting inevitably results in uneven cutting of the film roll, which easily causes problems such as uneven packaging during subsequent packaging, affecting the packaging effect and appearance. It is necessary to improve this. Summary of the Invention

[0006] The technical problem to be solved by the present invention is aimed at the deficiencies of the above-mentioned prior art,

[0007] To provide an instant film agent packaging machine.

[0008] To achieve the above object, the present invention provides the following technical solutions: An instant film packaging machine, comprising a frame, on which are provided a bottom film unwinding mechanism for unwinding the bottom film with the material film, a deviation rectifying mechanism for rectifying the deviation of the bottom film with the material film, a slitting mechanism for slitting and cutting the material film on the bottom film with the material film, a material film traction mechanism for traction of the material film after the pitch is completed, an upper packaging film unwinding mechanism for unwinding the upper packaging film for packaging the material film, a cutting mechanism for equally cutting the material film tractioned by the material film traction mechanism, a bottom film winding mechanism for winding the bottom film from which the material film has been peeled off, a lower packaging film unwinding mechanism for unwinding the lower packaging film for packaging the material film, a heat sealing mechanism for heat sealing the upper packaging film and the lower packaging film, a waste collection device, a packaging traction mechanism, a blanking mechanism and a discharging waste rejection device, characterized in that: on the frame is further provided a pitch mechanism for pitching the material film after being slit and cut by the slitting mechanism, the pitch mechanism includes a guiding roller and at least one pitch plate provided on the frame behind the guiding roller, the pitch plate is provided with multiple groups of equally spaced pitch structures, and the oral instant film guided by the guiding roller is twisted and then enters the pitch structures for pitching and then passes through the traction roller group. The frame is provided with splicing platforms between the bottom film unwinding mechanism with the material film and the bottom film deviation rectifying mechanism with the material film, at the front end of the unwinding direction of the upper packaging film unwinding mechanism, and at the front end of the unwinding direction of the lower packaging film unwinding mechanism. The splicing platform includes a platform plate, on both sides of the platform plate are provided oppositely arranged side plates, there is a gap between the side plates and rotatably arranged pressing rollers, the area between the two pressing rollers is the splicing area, between the side plates and above the pressing rollers are provided oppositely arranged guide rods, and connected to the guide rods is a cutting assembly that can reciprocally slide along the guide rods and cut the film located in the splicing area.

[0009] By adopting the above technical scheme, the working principle of the oral instant film packaging machine in the prior art is as follows: first, the base film with the material film is unwound by the base film unwinding mechanism, and the base film with the material film enters the slitting mechanism after passing through the correction mechanism, and the slitting mechanism is provided with a plurality of slitting knives arranged at equal intervals to cut the material film on the base film with the material film into strips of equal width, and the base film is rolled up by the base film winding mechanism so that the base film can be reused, and then the material film is pulled into the cutting mechanism by the material film traction mechanism for equal-length cutting, and the distance between adjacent material films is changed by the variable distance module after the cutting, and the upper packaging film unwinding mechanism on the frame unwinds the upper packaging film, and the upper packaging film is located above the material film, and the lower packaging film unwinding mechanism unwinds The lower packaging film is located below the material film. The three enter the heat sealing mechanism through the guide roller for heat sealing, and then enter the punching station through the packaging traction mechanism to be punched into independent small packages. That is to say, the oral instant film packaging machine in the prior art does not perform spacing after cutting the oral instant film into strips, but after cutting the oral instant film into strips and slicing it through a cross-cutter (cutting mechanism), the oral instant film is separated and packaged piece by piece in turn through a variable distance module. However, this method is not only inefficient, but the setting of the variable distance module will increase the production cost. The present invention adopts a spacing plate and a spacing structure pre-arranged on the spacing plate to separate the oral instant film after cutting in advance, and the oral instant film is twisted and then passes through the spacing structure and enters the material film In the traction roller group of the traction mechanism, the spacing between the spacing structures is adapted to the spacing of the oral instant film receiving grooves provided in the traction roller group, so that the twisted oral instant film can enter the oral instant film receiving groove straightly when it comes out of the spacing structure, thereby ensuring the traction effect. If the oral instant film strips do not pass through the spacing structure first but directly enter the traction roller group, since each oral instant film does not enter the oral instant film receiving groove of the traction roller group straightly, the two sides of each oral instant film are not exactly located in the oral instant film receiving groove. Although the oral instant film that comes out after being pulled by the traction roller group has the same length after being cut to equal length, it is difficult to ensure the area of ​​each piece, which affects the product quality and aesthetics. The present invention adopts the spacing structure The oral instant film cut into strips is spaced in advance to ensure that it is always located in the oral instant film receiving groove of the traction roller group when entering the traction roller group, to ensure the traction effect and the area of ​​each piece of oral instant film after subsequent equal-length cutting is consistent, to ensure product quality and no need to use a variable-pitch mold for variable pitch. After cutting, the oral instant film can be directly heat-sealed in two pieces of packaging film through a heat-sealing mechanism. Since the film rolls on the bottom film unwinding mechanism, the upper packaging film unwinding mechanism, and the lower packaging film unwinding mechanism are not infinitely long, the bottom film roll of the material film placed on the bottom film unwinding mechanism, the upper packaging film placed on the upper packaging film unwinding mechanism, and the lower packaging film placed on the lower packaging film unwinding mechanism need to be replenished in time after unwinding.In the traditional method, after the material roll is replenished on the unwinding mechanism, the end of the previous material roll and the head of the material roll to be unwound are manually bonded with adhesive tape and then cut. However, it is inevitable that the material roll will be cut unevenly by hand, which easily leads to the problem of uneven packaging during subsequent packaging, affecting the packaging effect and appearance. In the present invention, by providing a splicing platform, the operation method of the splicing platform is that through the pressure rollers arranged at intervals, one end of the pressure roller presses the head of the thin film to be spliced, and the other end of the pressure roller presses the tail of the thin film that is about to be exhausted. The heads and tails of the two rolls of thin films overlap in the splicing area, and then the cutting component on the guide rod is operated to simultaneously cut the two rolls of overlapping thin films in the splicing area, so that the same cutting marks are formed at the splicing parts of the two rolls of thin films. Therefore, after splicing with adhesive tape, the splicing part is flatter. Moreover, since the cutting component is connected between the two side plates through the relatively arranged guide rods, the straightness is ensured when the cutting component moves along the guide rod, and the straightness of the cutting marks on the thin film is better, making it more beautiful after splicing.

[0010] The above-mentioned instant dissolving film packaging machine can be further set as follows: the spacing structure includes mounting plates evenly distributed on the spacing plate. Each mounting plate is provided with a rotatably arranged first guide post. On one side of the first guide post on the mounting plate, at least two limiting posts are arranged at intervals with the first guide post. A gap for the oral instant dissolving film to pass through is formed between the first guide post and the limiting posts. The cutting component includes a sliding member with both ends respectively passing through the guide rods. A cutting tool is installed in the middle of the sliding member, and a cutting knife is arranged at one end of the cutting tool facing the splicing area.

[0011] By adopting the above technical solution, a plurality of evenly distributed mounting plates are arranged on the spacing plate. Each mounting plate is provided with a rotatably arranged first guide post and limiting posts that form a gap for the oral instant dissolving film to pass through with the first guide post. The oral instant dissolving film strip passes through the gap after being twisted and then twists back in the opposite direction and enters the corresponding oral instant dissolving film accommodating groove in the traction roller group. Since the first guide post is rotatably arranged, the oral instant dissolving film strip will not be stuck in the gap, but passes through the spacing plate along the gap under the action of the traction roller group, ensuring the traction effect and the consistency of the areas of each piece of oral instant dissolving film after subsequent equal-length cutting. The sliding member is operated to slide along the guide rod, and the overlapping parts of the two thin films in the splicing area are simultaneously cut by the cutting knife, which not only cuts quickly but also has a flat cut section.

[0012] The above-mentioned instant dissolving film packaging machine can be further set as follows: an open chute is provided in the spacing plate, and each mounting plate is installed in the chute and can slide. The cutting tool includes relatively arranged mounting blocks. One end of the mounting block is installed on the sliding member, and the cutting knife is installed between the two mounting blocks.

[0013] With the above technical solution, by providing an open chute in the spacing plate and slidably installing each mounting plate in the chute, the spacing between the mounting plates can be adjusted according to actual needs, improving the versatility of the spacing mechanism and meeting the spacing requirements for different products and different packages. Installing the cutting knife between the oppositely arranged mounting blocks can protect both ends of the cutting knife, improving the service life of the cutting knife and its safety during transportation.

[0014] The above-mentioned instant dissolving film packaging machine can be further configured as follows: The first guide post includes a first central axis fixedly installed in the mounting plate. A sleeve is sleeved outside the first central axis, and both ends of the sleeve are installed on the first central axis through bearings. The splicing area is a groove provided in the middle of the platform plate. A guide plate is installed in the groove, and a guide groove is opened in the middle of the guide plate. The cutting knife is arranged opposite to the guide groove.

[0015] With the above technical solution, the sleeve is installed on the first central axis through bearings. When the oral instant dissolving film strip passes by, the sleeve will rotate along the first central axis. Clamps can be installed at both ends of the sleeve to ensure that the sleeve is always on the first central axis during rotation and prevent it from falling off. By setting the splicing area as a groove, installing a guide plate in the groove, and opening a guide groove opposite to the cutting knife in the middle of the guide plate, the cutting knife moves along the guide groove during cutting, restricting the cutting trace of the film in the guide groove. And because of the presence of the guide groove, the cutting knife will not directly come into hard contact with the platform plate, thereby improving the service life of the cutting knife and the platform plate.

[0016] The beneficial effects of the present invention are as follows: Using the spacing mechanism to complete the spacing before cutting the oral instant dissolving film strip, eliminating the need to set up a variable spacing module, improving the production efficiency of the packaging machine and reducing the manufacturing cost of the packaging machine. Setting multiple splicing platforms on the oral instant dissolving film packaging machine facilitates the splicing of the bottom film, upper packaging film, and lower packaging of the film with materials, and using the semi-mechanization of the splicing platform to replace pure manual splicing and cutting greatly improves the flatness of the film splicing section, making the film packaging of the oral instant dissolving film more beautiful.
