Description

Technical Field

[0001] The utility model belongs to the technical field of medicine packaging, and in particular relates to a film coating device for a medicine packaging box. Background Art

[0002] During the drug production process, the tablets are packaged on the tablet plastic grid board, then laminated on the aluminum film, filled into the packaging box, and sprayed with the drug production information, including production batch number, production date, anti-counterfeiting spray code, etc. The packaging box needs to be laminated. Specifically, lamination is used to prevent the cardboard material drug packaging box from being damp and causing tablet contamination.

[0003] At the same time, the lamination can keep the medicines in the packaging box in a dry environment and relatively isolated from the outside world, thereby protecting the medicines and ensuring the safety of medication.

[0004] During the production process, lamination is completed on the lamination production line. Specifically, after the blank film roll is unrolled and transmitted from the material rack, it goes through processing steps such as cutting, adjusts the film size, and finally laminates on the packaging box.

[0005] During the transmission of the blank film roll, the film material is prone to deviation due to its great flexibility. Specifically, after the film roll is unwound, it is flexible and the unwinding transmission length is relatively long. Once in the production process, in order to effectively control the tensioning force, if the unwinding speed is too fast, the relaxed film is very likely to deviate. If the position of the deviated film is not corrected in time, a chain reaction will occur in the subsequent transmitted film, resulting in a large-scale deviation from the trajectory.

[0006] Therefore, in the actual production process, once the film is unrolled too fast and deviates, it can only be corrected manually. Specifically, the film is too light, and it is easy to control the correction force manually so as not to damage the film. However, the disadvantages of manual correction are also very obvious. When the film is seriously deviated, the length of the human arm is limited, and it is difficult to correct it effectively. In addition, the correction process requires a long time to ensure that the film is converted from the deviated state to the normal state. However, it is difficult to correct it manually for a long time. The current method can only be to stop the machine, completely correct the film, and then continue to unload and transmit. However, it undoubtedly greatly reduces production efficiency. Utility Model Content

[0008] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0009] A film laminating device for a medicine packaging box comprises a film laminating correction mechanism, wherein the film laminating correction mechanism comprises a correction frame, and film correction components are respectively assembled and connected at both ends of the correction frame;

[0011] The film correction rods are fixedly connected by connecting rods, and the connecting rods are assembled on the correction frame;

[0012] The lamination correction mechanism also includes a bottom mounting frame rotatably connected to the bottom position of the correction frame, and the bottom of the bottom mounting frame is equipped with a motor that drives the correction frame to rotate;

[0013] The film laminating device for the medicine packaging box also includes a film correction and pressing mechanism. After the film laminating correction mechanism corrects the film posture, the film is pressed by the film correction and pressing mechanism to increase the correction effect.

[0015] Preferably, the connecting rod is slidably connected to the correction frame;

[0017] Preferably, mounting arms bent toward left and right sides are formed at the front and rear ends of the bottom mounting frame respectively, and mounting claw plates are welded to the mounting arms.

[0018] Preferably, the film correction and pressing mechanism comprises film correction and pressing assemblies respectively connected to the left and right sides of the correction frame;

[0019] The film-correcting rear material pressing assembly comprises an arch-shaped correcting arm with an adjustable angle, and the inner end of the arch-shaped correcting arm is fixedly assembled and connected with a pressing wheel assembly.

[0020] Preferably, a pair of ear plates are fixedly connected to the correction frame, and an angle adjustment screw is threadedly connected between the ear plates;

[0021] The lower end of the bow-shaped correcting arm is fixedly connected to the angle adjusting screw.

Since the material of the film is relatively flexible, it is very convenient to drive it away. During the driving process, the film contacts the film correction rod, and multiple film correction rods arranged side by side are used to synchronously drive the film to realize the transmission posture of the correction film.

[0031] The above method can be used to correct the transmission posture of a flexible film in a simple, convenient and quick manner. 2. During the working process, the bow-shaped correction arm is rotated until the pressure wheel assembly connected to its inner end touches and presses on the film (during the rotation process, the angle adjustment screw is threadedly connected to the ear plate, so the horizontal displacement of the rotating bow-shaped correction arm moves slightly, but after rotating to press the material, the bow-shaped correction arm can remain motionless under the action of the threaded connection. The bow-shaped correction arm and the pressure wheel assembly are made of plastic material with a light texture and can maintain the positioning state after the angle is rotated). The contact and pressure method is rolling contact and pressure, which does not affect the horizontal movement of the film. After the contact and pressure, the force of the film correction rod to drive the film is relatively large, and the effect of driving and correcting the film posture is obvious, so that the flexible film will not "give way" during the film driving process.

[0041] Example 1

[0042] like Figure 1-4 As shown, a film coating device for a pharmaceutical packaging box includes a film coating correction mechanism, which includes a correction frame 1 (the shape of the correction frame 1 is: the longitudinal cross-section shape of the correction frame 1 is V-shaped, and the two ends of the correction frame 1 are inclined outward), and the two ends of the correction frame 1 are respectively equipped with film correction components.

[0043] During the film transmission process, the film is corrected by the film correction component on which side the film is deviated.

[0044] Specifically, the film correction assembly includes film correction rods 21 spaced apart on both sides, and a plurality of film correction rods 22 are rotatably connected to the film correction rods 21 (the film correction rods 22 are made of rubber, with a rotating shaft installed at the bottom, which is rotatably connected to the film correction rods 21).

[0045] At the same time, the film correction rods 21 are fixedly connected by connecting rods 23, and the connecting rods are assembled on the correction frame 1. Specifically, the connecting rods are slidably connected to the correction frame 1; the tops of both ends of the correction frame 1 are respectively threadedly connected with a plurality of locking bolts 231 for squeezing and positioning the connecting rods 23.

[0046] During the working process, the locking bolts 231 are loosened in advance and then the distance between the film correction rods 21 and film correction rods 22 on both sides and the correction frame 1 is adjusted by sliding, so as to better block the offset film. After adjustment, the locking bolts are locked.

[0047] At the same time, the coating correction mechanism also includes a bottom mounting frame 4 rotatably connected to the bottom position of the correction frame 1, and the bottom of the bottom mounting frame 4 is assembled and connected with a motor 3 that drives the correction frame 1 to rotate (specifically: the motor 3 uses a forward and reverse motor 3, its output shaft is rotatably connected to the bottom mounting frame 4, and is fixedly installed at the bottom center position of the correction frame 1).

[0048] During the working process, when the film is deviated to the left or right, the motor 3 drives the correction frame 1 to rotate, and the film correction component rotates to the left or right side to touch the film, and drives the deviated film inward. Since the material of the film is relatively flexible, it is very convenient to drive it away. During the driving process, the film contacts the film correction rod 22, and a plurality of film correction rods 22 arranged side by side are used to synchronously drive the film to realize the transmission posture of the correction film.

[0049] The above method can realize the correction of the transmission posture of the highly flexible film in a simple, convenient and quick way.

[0050] The front and rear ends of the bottom mounting frame 4 are respectively formed with mounting arms 41 bent toward the left and right sides, and mounting claw plates are welded on the mounting arms 41. According to the existing method, the mounting claw plates are installed on the frame of the processing equipment.

[0051] Example 2

[0052] like Figure 1-4 As shown, this embodiment is based on the structure of embodiment 1. During the process of driving and correcting the posture of the film, due to the relatively high flexibility of the film, the film is easy to "give way" during the driving process, that is, during the driving process, the driving force of the film correction rod 22 is not high, resulting in that the effect of driving and correcting the posture is not very obvious.

[0053] The above-mentioned film laminating device for the medicine packaging box further comprises a film correction and pressing mechanism 5. After the film laminating correction mechanism corrects the film posture, the film is pressed by the film correction and pressing mechanism 5 to increase the correction effect.

[0054] Specifically, the film correction and pressing mechanism 5 includes film correction rear pressing components respectively assembled and connected to the left and right sides of the correction frame 1; the film correction rear pressing component includes an angle-adjustable bow-shaped correction arm 51, and the inner end of the bow-shaped correction arm 51 is fixedly assembled and connected to a pressing wheel assembly. At the same time, a pair of ear plates are fixedly connected to the correction frame 1, and an angle adjustment screw 11 is threadedly connected between the ear plates; the lower end of the bow-shaped correction arm 51 is fixedly connected to the angle adjustment screw 11.

[0055] During operation, the bow-shaped correction arm 51 is rotated until the pressure wheel assembly connected to its inner end touches and presses the film (during the rotation process, the angle adjustment screw 11 is threadedly connected to the ear plate, so the horizontal displacement of the rotating bow-shaped correction arm 51 moves slightly, but after rotating to press the material, the bow-shaped correction arm 51 can remain motionless under the action of the threaded connection. The bow-shaped correction arm 51 and the pressure wheel assembly are made of plastic material, which is light in texture and can maintain the positioning state after the angle is rotated). The contact and pressure method is rolling contact and pressure, which does not affect the horizontal movement of the film. After the contact and pressure, the force of the film correction rod 22 to drive the rod film is relatively large, and the effect of driving and correcting the posture of the film is obvious, so that the flexible film will not "give way" during the film driving process.

[0056] Specifically, the pressing wheel assembly includes a fixing plate 52 vertically welded to the inner end of the bow-shaped correction arm 51, and a plurality of pressing wheels 53 are assembled and connected to the fixing plate 52. In actual working process, a pressing wheel 53 assembly is respectively arranged on the front and rear sides of the inner end of the bow-shaped correction arm 51 to increase the pressing surface.

[0057] Example 3

[0058] like Figure 1-4 As shown, based on the structure of Example 2, the pressure wheel 53 of this embodiment includes a pressure wheel frame 531, and a contact pressure wheel 532 is rotatably connected to the pressure wheel frame 531. At the same time, the pressure wheel frame 531 (the pressure wheel frame 531 is a U-shaped structure, and the fixed plate 52 slides in the U-shaped structure) is slidably connected to the fixed plate 52. At the same time, an elastic structure is assembled and connected to the fixed plate 52, and the pressure wheel frame 531 is elastically adjusted through the elastic structure. The elastic structure includes a vertical screw rod 533 fixedly connected to the fixed plate 52, and the vertical screw rod 533 is slidably connected to the pressure wheel frame 531; a spring 531 is sleeved on the vertical screw rod 533, and the two ends of the spring 531 are respectively fixedly connected to the fixed plate 52 and the inner side wall of the pressure wheel frame 531; a contact pressure nut that contacts and presses on the pressure wheel frame 531 is threadedly connected to the vertical screw rod 533.

[0059] Under normal circumstances, the spring 531 is in a compressed state. At this time, the pressure wheel frame 531 is kept in a tensioned state under the action of the contact pressure nut. When the position of the pressure wheel frame 531-contact pressure wheel 532 needs to be adjusted, such as adjusting it toward the outside, the contact pressure nut is loosened, and vice versa, the contact pressure nut is tightened. The purpose of this method is to fine-tune the pressure wheel frame 531-contact pressure wheel 532 until the pressure wheel frame 531-contact pressure wheel 532 can effectively contact the film, and to give the film sufficient tension after contact pressure, so as to ensure that the film can fully move during the process of correcting the film posture.

[0060] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
