Description

Technical Field

[0001] This utility model relates to the field of ring cutting machine technology, specifically to a bottle cap ring cutting machine. Background Technology

[0002] Currently, the molding and cutting of tamper-evident rings on plastic bottle caps mainly employs mechanical rotary ring cutters or laser cutting equipment. During injection molding, the tamper-evident ring is integrally formed with the bottle cap body, with a pre-designed break point structure created through mold design. The ring cutter removes injection flash and ensures the uniformity of the break points on the tamper-evident ring, allowing it to break smoothly upon opening, thus serving as an anti-counterfeiting measure. Laser cutting technology improves precision through non-contact processing, but the equipment cost is higher. Traditional mechanical ring cutters use rotating clamps with carbide blades for cutting. While low-cost and simple in structure, the blades are prone to wear, affecting product consistency. Furthermore, production efficiency is limited; traditional mechanical cutting speeds are typically below 1200 pieces / minute, making it difficult to match high-speed injection molding production capacity.

The intercepting cylinder drives the intercepting block to extend or retract from the end of the cap passage 22 to intercept or release the bottle cap.

[0055] When the intercepting cylinder drives the intercepting block to extend into the end of the cap channel 22, the intercepting block can extend into the bottle cap and stop the bottle cap at the end of the cap channel 22. As the cap feeding assembly 20 continuously supplies bottle caps, a certain amount of bottle caps accumulates on the roller rack, and the bottle caps are arranged in an orderly manner within the cap channel 22.

In order to improve the stability of the cutting ring cutter 42, a pressing plate can also be provided on the contact surface between the cutting ring cutter 42 and the upper cover plate 43 or the lower support plate 44.

[0068] The cutter support frame 41 may also include a height adjustment ring 48, which is connected to the upper cover plate 43 and the lower support plate 44 by fasteners, and is used to adjust the height of the cutting ring cutter 42.

[0069] The upper cover plate 43 has a first mounting groove 431 and a second mounting groove 432 on both sides, and a temperature measuring groove 433 on the top of the upper cover plate 43.

[0070] The temperature control structure 46 includes a first heating rod 461, a second heating rod 462, a third heating rod 463, a fourth heating rod 464, and a temperature measuring coupler 465.

[0071] The temperature control system 47 includes a temperature control module, which is electrically connected to the first heating rod 461, the second heating rod 462, the third heating rod 463, and the fourth heating rod 464 via a solid-state relay. The temperature control module is also signal-connected to the thermocouple 465. Based on the feedback signal from the thermocouple 465, the temperature control module sends a control command to the solid-state relay, and the solid-state relay controls the on / off state of the first heating rod 461, the second heating rod 462, the third heating rod 463, and the fourth heating rod 464 according to the control command.

[0072] The lower support plate 44 has a meshing tooth 443 on the side near the ring-cutting frame assembly 30, and the meshing tooth 443 can mesh with the anti-slip tooth on the outside of the bottle cap.

[0073] In use, the first heating rod 461, the second heating rod 462, the third heating rod 463, and the fourth heating rod 464 are respectively embedded in the pre-drilled holes (first mounting groove 431, second mounting groove 432, third mounting groove 441, and fourth mounting groove 442) on both sides of the lower support plate 44 and the upper cover plate 43; the lower support plate 44, the pressing plate, the cutting ring blade 42, and the upper cover plate 43 are stacked from bottom to top, and the two fastening pillars pass through the pre-drilled holes of each stacked component. The cover plate pressing ring is then tightened with screws to press each stacked component firmly.

[0074] The control system issues a command, and the temperature control system 47 starts controlling the solid-state relay to close each heating rod (first heating rod 461, second heating rod 462, third heating rod 463, and fourth heating rod 464) according to the set temperature. During this process, the heat generated by each heating rod is conducted to the ring cutter 42 through the metal. The thermocouple 465 detects the temperature of the ring cutter 42 in real time. When the ring cutter 42 reaches the set temperature, the temperature control module sends a pulse signal to control the opening and closing of the solid-state relay. Within the pulse cycle, the working state of each heating rod is changed to control the temperature of the ring cutter 42. When the temperature is stable, the bottle cap is clamped on the arc-shaped blade of the ring cutter 42 and rotates along the normal line perpendicular to the blade surface. When the bottle cap passes through the specific tooth profile area of ​​the lower support plate 44, the anti-slip teeth of the bottle cap engage with the meshing teeth 443, and the bottle cap rotates. By controlling the number and arc length of each arc-shaped blade array, corresponding marks can be left on the bottle cap. By controlling the spacing of each arc-shaped blade, different mark shapes can be obtained.

[0075] Based on the above structure, in the use of the bottle cap ring cutting machine of this embodiment, bottle caps with a single row of openings facing upwards enter from above the roller row of the cap feeding assembly 20. The intercepting cylinder in the cap feeding assembly 20 is closed, and the intercepting block extends into the inner wall of the bottle cap to jam the bottle cap and stop the bottle cap from entering the ring cutting frame. Until a certain number of bottle caps are accumulated on the cap channel 22, the intercepting cylinder retracts, and the bottle caps are released and orderly enter the cap conveying groove 321 of the cap feeding star wheel 32. Because of the height difference between the anti-slip teeth of the plastic bottle cap and the forming position of the anti-theft ring, as the rotating frame body 31 rotates, the upper follower component moves downward, driving the push rod to extend into the bottle cap. The elastic element inside the push rod is compressed to generate elastic force to resist the bottle cap. After the adjustment of the guide plate 21 in the cap feeding assembly 20, the bottle cap is positioned on the same axis as the bottle cap holding mold 351. As the rotating frame body 31 continues to rotate, the lower follower component and the upper follower component rise simultaneously. The bottle cap held between the two is lifted to the preset cutting ring position. The meshing teeth 443 on the lower support plate 44 on the cutter assembly 40 will mesh with the anti-slip teeth of the bottle cap, driving the bottle cap to start rotating. At the same time, the bottle cap will move towards the axis of the rotating frame body 31 under the push of the lower support plate 44 until the side wall of the bottle cap is circumferentially attached to the side wall. The bottle cap rotates once along the arc-shaped blade of the cutting ring cutter 42 to form the anti-theft ring mark on the bottle cap. A synchronous wheel 352 is installed on the upper follower component 35, which, driven by the synchronous rotation mechanism, enables the synchronous rotation of the bottle cap holding mold 351 at different speeds, improving the consistency of the anti-theft ring forming for each bottle cap. The bottle cap sidewall holding mold rotates synchronously with the bottle cap. After the anti-theft ring is formed, the top cover cam inside the ring cutting frame assembly 30 pushes the bottle cap out, aligning the bottle cap axis with the axis of the bottle cap holding mold 351. At this point, the upper and lower follower components descend simultaneously, causing the bottle cap held between them to return to its initial height. When the frame body 31 rotates to the cap exit position, the cap exiting plate and cap exiting baffle, which rotate synchronously with the cap inlet star wheel 32, separate the bottle cap from the ring cutting frame assembly 30. The cap exiting plate then separates the bottle cap onto the conveying path of the cap exiting pneumatic conveying assembly 60 through centrifugal force, and the bottle cap is then conveyed to the next process by air force.

[0077] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
