Description

Technical Field

[0001] The invention relates to the technical field of bottle cap packaging, and in particular to a quantitative packaging line for medicinal bottle caps. Background Art

[0002] Most of the medicinal bottle caps are made of PE and PP as the main raw materials. The most commonly used is the ordinary threaded cap, which achieves the function of sealing by matching the thread inside the bottle cap with the thread of the bottleneck. The medicinal bottle cap is an important component of the supporting packaging container of the pharmaceutical packaging bottle. The bottle cap is mostly in direct contact with the medicine, and plays an important role in gas barrier, moisture prevention and pollution prevention. On the one hand, the medicinal bottle cap should prevent the medicine in the bottle from escaping; on the other hand, it should prevent any foreign matter from entering the bottle.

[0003] At present, the existing medicinal bottle caps usually need to be packaged and transported after they are produced, and the existing packaging method is usually: the staff directly puts a certain number of medicinal bottle caps into a plastic bag, weighs the plastic bag, estimates the number of medicinal bottle caps, marks the number of medicinal bottle caps on the surface of the plastic bag, and then puts the plastic bag into a logistics transport box for transportation.

[0004] In the above scheme, this packaging method not only makes the medicinal bottle caps easily corroded by the external environment, resulting in quality problems of the medicinal bottle caps, but also occupies a large space and increases transportation costs. At the same time, the packaging efficiency is low, and the number of medicinal bottle caps cannot be accurately calculated, which increases the labor intensity of the staff. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a quantitative packaging line for medicinal bottle caps. By providing an arranging and pushing mechanism, a paper adding mechanism and a heat shrink film packaging machine, the medicinal bottle caps can be automatically quantitatively packaged, thereby solving the problems of low efficiency of the existing packaging method, inability to accurately calculate the number of medicinal bottle caps, and increased labor intensity of the staff. At the same time, the strength and aesthetics of the finished product after packaging are improved, and it is ensured that the medicinal bottle caps are not easily eroded by the external environment.

[0006] The solution of the present invention to solve the technical problem is: A quantitative packaging line for medicinal bottle caps comprises a medicinal bottle cap conveying line for conveying medicinal bottle caps, a padding mechanism for adding inner pads into the medicinal bottle caps, an arranging and pushing mechanism for arranging the medicinal bottle caps, a paper adding mechanism for adding wrapping paper before packaging the medicinal bottle caps, and a heat shrink film packaging machine for packaging the medicinal bottle caps, wherein the heat shrink film packaging machine comprises a conveying device, a film laminating and hot cutting device, and an oven.

At the same time, in the process of pushing several rows of medicinal bottle caps, the padding mechanism is started. The paper mechanism pads the packaging paper at the lower ends of the rows of medicinal bottle caps, thereby improving the strength of the medicinal bottle caps after packaging. At the same time, the setting of the packaging paper can improve the aesthetics of the finished product after packaging, and the parameters such as the specifications and quantity of the medicinal bottle caps can be clearly seen. The film covering and hot cutting device is started to package the rows of medicinal bottle caps, and at the same time, the excess packaging film is cut off, and then the packed rows of medicinal bottle caps are driven by the conveying device to be conveyed to the oven, and the oven is started to heat the packaging film to shrink the packaging film, and then the packaging film is made to fit tightly to the surface of the medicinal bottle caps, thereby completing the quantitative packaging of the medicinal bottle caps.

[0008] By providing an arranging and pushing mechanism, a paper adding mechanism and a heat shrink film packaging machine, the medicinal bottle caps can be automatically packaged in a quantitative manner, thereby solving the problems of low efficiency of the existing packaging method, inability to accurately calculate the number of medicinal bottle caps, and increased labor intensity of the staff.

After the multiple medicinal bottle caps are driven to move between the baffle and the pushing assembly through the medicinal bottle cap conveyor line, the baffle is controlled to reset, and the pushing assembly is started to drive a row of medicinal bottle caps of the required number to be pushed into the positioning rack. The above operation is repeated several times, so that several rows of medicinal bottle caps are arranged in the positioning rack.

[0017] The invention is further configured as follows: the pushing component includes a fourth cylinder arranged at the upper end of the machine body, a push plate is fixed on the output end of the fourth cylinder, a linkage plate is fixed on the upper end of the push plate, a linkage groove is formed on the upper end of the linkage plate, and a linkage rod inserted into the linkage groove is fixed on the upper end of the positioning frame.

[0018] Through the above technical solution, when it is necessary to push several rows of medicinal bottle caps onto the conveying device, the fourth cylinder is started to drive the push plate to move, so that several rows of medicine bottle caps can be pushed onto the conveying device. At the same time, the movement of the push plate drives the linkage plate to move. When the linkage rod rests on the inner wall of the linkage groove, it can drive the positioning frame to move together, thereby ensuring that the rows of medicinal bottle caps will not be messed up during the process of pushing them.

At the same time, in the process of the arranging and pushing mechanism pushing several rows of medicinal bottle caps, the two clamping cylinders are pushed to move, so that the packaging paper is pulled out, and then the packaging paper can be padded at the lower end of several rows of medicinal bottle caps. After the packaging paper is pulled out to the required length, the motor is started to drive the two paper feeding rollers to rotate towards each other, so that the packaging paper can be torn along the easy-tear line. When the arranging and pushing mechanism pushes several rows of medicinal bottle caps onto the conveying device, the two clamping cylinders are controlled to loosen, so that the packaging paper is padded at the lower end of several rows of medicinal bottle caps, and then the arranging and pushing mechanism is controlled to reset.

[0024] Through the above technical solution, when the visual sensor senses that there is no inner pad added in the medicinal bottle cap, the air outlet pipe is started to blow the medicinal bottle cap without the inner pad added into the guide channel, thereby ensuring that the quality of the medicinal bottle cap is not affected, and the medicinal bottle cap falls into the receiving box after passing through the guide channel, so that the medicinal bottle cap can be collected.

[0025] The invention is further configured such that the spacing between the positioning frames is equal to the length of a row of medicinal bottle caps.

[0026] By means of the above technical solution, when several rows of medicinal bottle caps are pushed into the positioning rack, the medicinal bottle caps are prevented from being messed up.

[0053] Working principle: When it is necessary to quantitatively package the medicinal bottle caps, several medicinal bottle caps are conveyed through the medicinal bottle cap conveyor line 1, and the first cylinder 11 is started to drive the sliding block 6 to move downward, and at the same time drive the connecting frame to move downward, so that the air outlet ends of several blowing pipes 12 are located in several medicinal bottle caps, and the blowing pipes 12 are started to clean the dust of several medicinal bottle caps, and then the sliding block 6 is controlled to move upward, and at the same time, under the action of the rack 10, the half gear 9 is driven to rotate, thereby driving the flip block 7 to flip 180°, so that several suction cups 8 are set upward, and continue to drive the flipped flip block 7 to move upward after flipping, so that several suction cups 8 are against the lower end of the inner pad, and start several suction cups 8 to suck several inner pads, and then control the sliding block 6 to move downward, and under the action of the rack 10, The flip block 7 is reset, and then the several suction cups 8 are set downward, the second cylinder 13 is started, and the positioning plate 14 is driven to move, so that one end of the several medicinal bottle caps abuts against the side wall of the medicinal bottle cap conveying line 1, and the other ends of the several medicinal bottle caps abut against the several positioning grooves on the side wall of the positioning plate 14, so that the several medicinal bottle caps are positioned and fixed, and the sliding block 6 is continued to move downward, so that the several suction cups 8 move into the several medicinal bottle caps, so that the several inner pads are placed in the several medicinal bottle caps, and the third cylinder 16 is started to drive the baffle 17 to move downward, so that a channel for placing multiple medicinal bottle caps is set between the baffle 17 and the push plate 20, when several medicinal bottle caps with added inner pads are conveyed to between the baffle 17 and the push plate 20, the baffle 17 is controlled to reset, and the fourth cylinder is started. The cylinder 19 drives the push plate 20 to move, thereby driving a row of the required number of medicinal bottle caps to be pushed into the positioning frame 18. The above operation is repeated several times, so that several rows of medicinal bottle caps are arranged in the positioning frame 18. The push plate 20 is then moved to drive the linkage plate 21 to move. When the linkage rod 22 abuts against the inner wall of the linkage groove 2101, the positioning frame 18 can be driven to move together. At the same time, the fifth cylinder 28 is started to drive the lifting plate 29 to move downward, so that the protruding ends of the packaging paper passing through the two paper guides 27 are located in the clamping claws of the two clamping claw cylinders 32. The two clamping claw cylinders 32 are started to clamp the packaging paper. Therefore, in the process of pushing several rows of medicinal bottle caps, the movement of the positioning frame 18 will drive the two clamping claw cylinders 32 to move, thereby pulling the packaging paper out. Then, the packaging paper can be placed at the lower end of several rows of medicinal bottle caps. After the packaging paper is pulled out to the required length, the motor 26 is started to drive the two paper feeding rollers 24 to rotate towards each other, so that the packaging paper can be torn along the easy-tear line. After the arrangement and pushing mechanism pushes several rows of medicinal bottle caps onto the conveying device 2, the two clamping claw cylinders 32 are controlled to loosen, so that the packaging paper is placed at the lower end of several rows of medicinal bottle caps. The arrangement and pushing mechanism is then controlled to reset. At the same time, under the action of the compression spring 33, the two clamping claw cylinders 32 are driven to reset, and the film coating and hot cutting device 3 is started to package several rows of medicinal bottle caps. At the same time, the excess packaging film is cut off, and then the packaged rows of medicinal bottle caps are driven to be transported to the oven 4 through the conveying device 2. The oven 4 is started to heat the packaging film to shrink the packaging film.Then the packaging film is closely attached to the surface of the medicinal bottle cap, thereby completing the quantitative packaging of the medicinal bottle cap.
