Technical Field

[0001] The utility model relates to the technical field of recycling aluminum-plastic bottle caps, in particular to a stripping mechanism and a cap stripping machine. Background Art

[0002] Existing capping machines, such as the CN202110583812.3 suction pad capping integrated machine, separate the rubber plug and the aluminum-plastic cap by pushing the piercing head upward to pierce the riveted joint of the aluminum-plastic cap. The piercing head continues to rise to push out the rubber plug in the aluminum-plastic cap. In order to facilitate the piercing head to pierce the aluminum-plastic cap, the piercing head is pointed, which causes the center of the rubber plug to be deformed or punctured during the ejection process. The separated rubber plug cannot be reused, and the recycling rate of the aluminum-plastic bottle cap is not high. Summary of the invention

DETAILED DESCRIPTION

[0022] The utility model will be further described below in conjunction with the accompanying drawings.

[0023] like Figure 1 , Figure 2 and Figure 5As shown, the preferred embodiment of the capping machine of the utility model includes a stripping mechanism, a turntable 2, a running track 3 and a reset track 4. The stripping mechanism is arranged on the turntable 2, the running track 3 is arranged around the turntable 2, the running track 3 is fixed on the bracket 6, the running track 3 is arranged corresponding to the stripping mechanism, the stripping mechanism travels on the running track 3, and the running track 3 supports and adjusts the height of the running track 3. The running track 3 has an ascending section and a descending section, the ascending section and the lower shelf section are smoothly transitioned, which is convenient for the stripping mechanism to travel, the stripping mechanism travels in the ascending section, the stripping mechanism will gradually rise to strip the aluminum-plastic bottle cap into an aluminum-plastic cap and a rubber plug, and the descending section of the running track 3 is used to provide enough space for the stripping mechanism to descend. The reset track 4 is on the outer side of the turntable 2, and the reset track 4 is arranged corresponding to the descending section of the running track 3. The reset track 4 guides the stripping mechanism to descend to ensure that the stripping mechanism can be reset. Of course, a spring can also be used to replace the reset track 4 for reset. The turntable 2 drives the stripping mechanism to move on the running track 3. The stripping mechanism rises or falls according to the height of the running track 3. When the stripping mechanism passes through the reset track 4, the reset track 4 forces the stripping mechanism to reset, that is, to ensure that the stripping mechanism can be separated from the aluminum-plastic cover.

[0024] like Figure 3 and Figure 4As shown, the stripping mechanism includes a puncture head 11, a running wheel 12, a reset wheel 13, a positioning pin 14 and a quick connector 15. The puncture head 11 is inserted on the turntable 2. The puncture head 11 can be lifted vertically on the turntable 2. The positioning pin 14 is fixed on the turntable 2. The positioning pin 14 is used to position the puncture head 11, so that the puncture head 11 cannot rotate and can only be lifted vertically. The running wheel 12 is installed at the lower end of the puncture head 11 through the shaft 16. The running wheel 12 runs on the running track 3. The running track 3 is used to support and adjust the height of the running wheel 12, thereby changing the height of the puncture head 11. The shaft 16 bearing can be used as the running wheel 12, which can reduce parts and reduce costs. The reset wheel 13 is installed on the shaft 16. The top surface of the reset wheel 13 contacts the bottom surface of the reset track 4. The reset track 4 guides the height of the reset wheel 13, so that the puncture head 11 is reset. The shaft 16 bearing can be used as the reset wheel 13, which can reduce parts and reduce costs. The reset wheel 13 and the running wheel 12 are installed on the same shaft 16, which can reduce the number of shafts 16 and reduce costs. The quick connector 15 is fixed on the puncture head 11. The straight-line distance between the top surface of the running track 3 and the bottom surface of the reset track 4 is not less than the sum of the radii of the running wheel 12 and the reset wheel 13, ensuring that the stripping mechanism will not be stuck between the running track 3 and the reset track 4. The quick connector 15 is used to connect with an external air source, and the air source supplies high-pressure gas to the quick connector 15. The puncture head 11 has an airway 111, and the quick connector 15 is connected to the airway 111. A puncture portion 17 is provided on the top of the puncture head 11, and the puncture portion 17 is used to puncture the aluminum-plastic cover. The air outlet of the airway 111 is located on the top surface of the puncture portion 17, and the high-pressure gas is ejected from the top surface of the puncture portion 17. The air outlet of the airway 111 is usually located at the center of the top surface, so that the rubber plug can be separated smoothly.

[0025] The bottom of the puncture head 11 is provided with a receiving notch 112, and the running wheel 12 is located in the receiving notch 112, so as to reduce the overall height of the puncture mechanism and achieve the purpose of reducing the volume. The puncture head 11 has a positioning groove 113 that limits the puncture head 11, and the positioning pin 14 extends into the positioning groove 113. The width of the positioning groove 113 is the same as the diameter of the positioning pin 14. The positioning pin 14 limits the rotation of the puncture head 11, so that the puncture head 11 can only go straight up and down on the turntable 2, so that the running wheel 12 and the running track 3 always keep the same direction, and the reset wheel 13 and the reset track 4 always keep the same direction.

[0026] The puncture portion 17 is integrally formed with the puncture head 11, which is convenient for processing and manufacturing and reduces the number of assembly steps. The top surface of the puncture portion 17 is a plane, and the air outlet of the airway 111 is located at the center of the top surface, which reduces the risk of the rubber plug being ruptured or deformed. In other embodiments, the top surface can also be set as a curved surface. The puncture portion 17 is in a truncated cone shape, so that the cross section of the puncture portion 17 is approximately triangular, which is convenient for puncturing the aluminum-plastic cover.

[0027] When in use, the running wheel 12 runs on the ascending section of the running track 3, thereby gradually raising the height of the running wheel 12, and the running wheel 12 drives the puncture head 11 and the puncture part 17 to rise, gradually puncturing the aluminum-plastic cover. When the aluminum-plastic cover is punctured, the rubber plug and the aluminum-plastic cover form a closed space, and the high-pressure gas continues to spray from the air outlet of the airway 111, so that the pressure of the space continues to increase. When the pressure is greater than the bonding force between the rubber plug and the aluminum-plastic cover, the rubber plug is separated from the aluminum-plastic cover, thereby completing the stripping. The running wheel 12 continues to run, and the running wheel 12 runs on the descending section of the running track 3. The reset track 4 guides the reset wheel 13 to move downward, driving the puncture head 11 to descend, so that the puncture head 11 is separated from the aluminum-plastic cover. In order to facilitate the collection of the rubber plug, a suction nozzle 5 is correspondingly arranged above the puncture mechanism to adsorb the rubber plug. The rubber plug is separated from the aluminum-plastic cover by air pressure, and the rubber plug will not be deformed or punctured, and the rubber plug can be recovered, thereby improving the recycling rate.

[0028] The above are only implementation methods of the present utility model, and are not intended to limit the patent scope of the present utility model. Any equivalent structure made using the contents of the specification and drawings of the present utility model, directly or indirectly used in other related technical fields, are also within the patent protection scope of the present utility model.
