Description

Technical Field

[0001] This application relates to the field of blister packaging technology, specifically a feeding structure for blister packaging. Background Technology

[0002] Blister boxes are plastic packaging boxes made by heating a flat, rigid plastic sheet until it softens, then vacuum-forming it onto a mold surface, and finally cooling it to form the final shape. These boxes can be used for packaging various products, including but not limited to plastic packaging, lighting fixtures, advertising, and decoration.

[0003] In the blister box packaging process, the feeding stage mainly relies on traditional conveying machinery, that is, the blister boxes are directly transported from the starting point to the preset fixed position in a straight line. This single conveying mode is particularly limited when dealing with complex packaging needs, that is, it is difficult to flexibly adjust the conveying direction or path of the blister boxes according to the needs of the packaging process, which limits the flexibility and adaptability of the packaging production line. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and propose a feeding structure for blister box packaging to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides a feeding structure for blister box packaging, including a device frame, a processing conveyor fixedly installed on the device frame, a feeding conveyor provided on the device frame, a number of trays provided on the conveyor belt of the feeding conveyor, a material distribution hopper provided on the outer surface of the device frame near the top of the feeding conveyor, a guide plate provided inside the material distribution hopper, a material distribution channel provided at the bottom of the material distribution hopper, a path changing mechanism provided inside the material distribution hopper, and two sets of material distribution channels symmetrically distributed at the bottom of the material distribution hopper.

[0006] Preferably, the path changing mechanism includes a fixed frame fixedly connected inside the dispensing hopper, and a rotating shaft is rotatably connected to the inner surface of the fixed frame. The path changing mechanism allows the blister packs falling from the dispensing hopper to be discharged from different dispensing channels.

[0007] Preferably, the outer surface of the rotating shaft is provided with a shift plate, and the fixed frame is provided with a motor.

[0008] Preferably, the output end of the motor is fixedly connected to the turntable, and a guide shaft is movably inserted through the inner side of the turntable.

[0009] Preferably, a collar is fixedly connected to the top of the guide shaft, and an offset rod is slidably connected to the inner surface of the collar.

[0010] Preferably, both ends of the offset rod are rotatably connected to offset frames, and the inner surface of the offset frame is fixedly sleeved with the outer surface of the rotating shaft.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The feeding structure for this blister packaging uses a feeding conveyor to pour the blister boxes from the tray into the feeding hopper. By introducing a path changing mechanism, the conveying path of the blister boxes can be dynamically adjusted. This dynamic adjustment allows the production line to quickly and flexibly change the conveying direction and path of the blister boxes according to the needs of different packaging processes, without replacing the entire conveying system or stopping the machine for adjustment, thereby greatly improving the flexibility and responsiveness of the production line.

[0013] 2. The blister packaging uses a feeding structure. Workers only need to place the blister boxes on the processing conveyor, and the automatic feeding system will complete the subsequent conveying and distributing work. This not only reduces the labor intensity of workers, but also reduces errors and delays caused by human factors, thereby improving the overall production efficiency. Attached Figure Description

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Please see Figure 1-3A feeding structure for blister box packaging includes a device frame 1, a processing conveyor 2 fixedly installed on the device frame 1, a feeding conveyor 3 provided on the device frame 1, several sets of trays 4 provided on the conveyor belt of the feeding conveyor 3, a material distribution hopper 5 provided on the outer surface of the device frame 1 near the top of the feeding conveyor 3, a guide plate 6 provided inside the material distribution hopper 5, a material distribution channel 7 provided at the bottom of the material distribution hopper 5, and a path changing mechanism provided inside the material distribution hopper 5.

[0020] Through the above technical solution, the blister boxes are conveyed on the processing conveyor 2 and continuously fed onto the tray 4 by manual labor. The feeding conveyor 3 feeds the blister boxes into the tray 4. After reaching the top of the feeding conveyor 3, the blister boxes are tilted into the distribution hopper 5. During this process, the blister boxes can be guided to different distribution channels 7 by the path changing mechanism (the two distribution channels 7 are symmetrically distributed at the bottom of the distribution hopper 5 and are on the same horizontal plane).

[0021] Specifically, the path changing mechanism includes a fixed frame 8 fixedly connected inside the distribution hopper 5, and a rotating shaft 9 is rotatably connected to the inner surface of the fixed frame 8.

[0022] Through the above technical solution, during the process of the rotating shaft 9 being driven to rotate within the fixed frame 8, it will be linked to the deflector plate 10 to deflect at a certain angle, thereby changing the conveying path of the blister box through the deflection of the deflector plate 10.

[0023] Specifically, a shift plate 10 is provided on the outer surface of the rotating shaft 9, and a motor 11 is provided on the fixed frame 8.

[0024] Through the above technical solution, as the motor 11 drives the turntable 12 to rotate, it will drive the guide shaft 13 to perform circular motion.

[0025] Specifically, the output end of the motor 11 is fixedly connected to the turntable 12, and the inner side of the turntable 12 is movably provided with a guide shaft 13.

[0026] Through the above technical solution, as the guide shaft 13 rotates with the turntable 12, it is relatively limited by the upper collar 14 and the offset rod 15, which allows the guide shaft 13 to move back and forth on the turntable 12.

[0027] Specifically, a collar 14 is fixedly connected to the top of the guide shaft 13, and an offset rod 15 is slidably connected to the inner surface of the collar 14.

[0028] Through the above technical solution, the collar 14 can slide flexibly along the outer surface of the offset rod 15 while rotating. During this period, the collar 14 will drive the offset rod 15, causing the offset rod 15 to deflect to a certain extent.

[0029] Specifically, both ends of the offset rod 15 are rotatably connected to offset brackets 16, and the inner surface of the offset brackets 16 is fixedly sleeved with the outer surface of the rotating shaft 9.

[0030] With the above technical solution, due to the diameter limitation of the turntable 12, the offset frame 16 will not touch the guide plate 6 during the deflection process, that is, the offset frame 16 can deflect smoothly at a certain angle.

[0031] Working Principle: During the packaging and feeding process, blister boxes are continuously conveyed on the processing conveyor 2 and placed onto trays 4 by workers on the production line. The feeding conveyor 3 then feeds the blister boxes onto the trays 4. When the blister boxes reach the top of the feeding conveyor 3, they are tilted into the dispensing hopper 5 and, guided by the limiting action of the deflector plate 10 and the guide plate 6, fall into the dispensing channel 7, ultimately entering the corresponding area for the next packaging process. During this process, a path-changing mechanism can guide the blister boxes to different dispensing channels 7 (the two dispensing channels 7 are symmetrically distributed at the bottom of the dispensing hopper 5, guiding the blister boxes in completely opposite directions). At this point, only motor 1 needs to be turned on. 1 drives the turntable 12 to rotate. During the rotation of the turntable 12, the guide shaft 13 will move in a circular motion. During the circular motion of the guide shaft 13, the collar 14 will be driven to slide along the offset rod 15, thereby driving the offset rod 15 to deflect (that is, the offset rod 15 will move in a circular motion at a certain angle along the rotating shaft 9). During this period, the offset brackets 16 at both ends of the offset rod 15 will deflect accordingly, and drive the rotating shaft 9 to rotate through the fixed frame 8, thereby driving the deflecting plate 10 to deflect. The top of the deflecting plate 10 is deflected to different positions in the material distribution hopper 5. It can cooperate with the corresponding guide plate 6 to change the feeding direction of the blister box, so that it falls into different material distribution channels 7, so as to flexibly adjust the conveying path.

[0032] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
