Description

Technical Field

[0001] The utility model relates to the technical field of bottle cap ring cutting machines, in particular to a ring cutting device for producing and processing plastic bottle caps. Background Art

[0002] During the production and processing of plastic bottle caps, a ring cutting device for producing and processing plastic bottle caps is required to cut a tear line on the anti-theft ring on the bottle cap. However, the existing ring cutting device for producing and processing plastic bottle caps has many problems or defects.

[0003] There are some problems in the processing of the existing ring cutting machine that need to be improved. For example, China's authorized patent CN218699044U discloses a plastic bottle cap ring cutting device and CN210705031U discloses a plastic bottle cap production and processing ring cutting device. The above two devices both use an external clamping method to clamp the bottle cap to achieve the clamping purpose. The problem with this clamping method is that since the bottle cap is made of plastic and is usually thin, this method of clamping the bottle cap from the outside can easily cause the bottle cap to deform when subjected to force, and the bottle cap sinks inward, thereby resulting in a decrease in the ring cutting accuracy. In severe cases, the bottle cap is damaged due to excessive deformation. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown, the utility model provides a technical solution: a ring cutting device for producing and processing plastic bottle caps, comprising a machine table 1, a support column 2 is arranged on the top of the machine table 1, a cylinder 3 for containing the bottle caps is arranged on the support column 2, and the cylinder 3 is connected from top to bottom. It should be particularly noted that in order to prevent the phenomenon that multiple bottle caps are detached together when adjacent bottle caps are detached from the bottom of the cylinder 3, a valve plate can be arranged at the bottom of the cylinder 3 to control the orderly falling of the bottle caps. This is a prior art and will not be described in detail.

[0026] like Figure 2 As shown, a through groove 4 is provided in the middle of the machine 1, and the through groove 4 is located directly below the cylinder 3. The inner cavity of the machine 1 is provided with a liftable first cylinder 5, and the free end of the first cylinder 5 is installed with an inner support block 6 for supporting the bottle cap from the inside, and the inner support block 6 is pressed against the inner wall of the bottle cap to prevent the bottle cap from sinking inward.

[0027] like Figure 2-3 As shown, the machine 1 is also provided with a bottle cap pressing component and a waste cleaning component.

[0028] like Figure 1 As shown, the bottle cap pressing assembly includes a fourth cylinder 14 which can be raised and lowered, and a pressing piece 15 is installed at the free end of the fourth cylinder 14. The pressing piece 15 can penetrate into the cylinder body 3 and press the bottle cap therein.

[0029] like Figure 2 As shown, the inner cavity of the machine 1 is also provided with a motor 7, and a driving gear 8 is installed at the output end of the motor 7. The driving gear 8 is located outside the machine 1 and can drive the bottle cap to rotate. The outer side of the bottle cap has a thread that just meshes with the driving gear 8.

[0030] like Figure 3 As shown, a second cylinder 9 which can be horizontally extended is arranged on the right side of the machine 1, and a cutter disc 10 is installed on the free end of the second cylinder 9. The cutter disc 10 is provided with blades 101 for circular cutting of the bottle caps. There are at least two blades 101, and there are gaps between the blades 101, thereby forming spaced cutting lines.

[0031] like Figure 3As shown, a third cylinder 11 which can be extended forward and backward is arranged in front of the machine 1, a push plate 12 is installed at the free end of the third cylinder 11, and a cleaning brush 121 is installed at the right bottom of the push plate 12. When the push plate 12 pushes the bottle cap, the cleaning brush 121 at its bottom can push the waste chips through the filter 17 and fall into the chip discharge bucket 18, and the waste chips then fall into the collection box 19.

[0032] like Figure 1 As shown, a rotatable conveyor belt 13 (driven by an external motor) is arranged at the rear of the machine 1 .

[0033] like Figure 3 As shown, the waste chip cleaning assembly includes a chip groove 16 opened at the right rear of the through groove 4, and a filter screen 17 is arranged on the chip groove 16. The purpose of setting the filter screen 17 is to prevent the bottle cap from falling or getting stuck in the chip groove 16, and the waste chips can directly pass through the filter screen 17. A chip bucket 18 is arranged below the chip groove 16, and a collection box 19 is arranged at the outlet of the chip bucket 18.

[0034] Meanwhile, the contents not described in detail in this specification belong to the prior art known to the professional and technical personnel in this field.

[0035] When in use, first stack the bottle caps to be cut (marked a in the figure) into the cylinder 3 in sequence (with the bottle mouths of the bottle caps facing downward), and at the same time start the first cylinder 5 to drive the inner support block 6 to be slightly higher than the through groove 4, and the inner support block 6 directly enters the inner wall of the bottle cap located at the bottom of the cylinder 3 (at this time, a small part of the top of the bottle cap is still in the cylinder 3 to prevent the bottle cap from completely falling out of the cylinder 3).

[0036] Then, the fourth cylinder 14 is turned on to drive the clamping piece 15 to penetrate into the cylinder 3 and exert a downward clamping force on the bottle cap to ensure that the bottle cap does not jump up and down (it should be noted that the clamping force needs to be appropriate, and too large a force may cause difficulty in rotating the bottle cap).

[0037] Then, the second cylinder 9 is turned on to drive the cutter disc 10 to the right side of the bottle cap, and then the motor 7 is turned on to drive the drive gear 8 to rotate. The drive gear 8 engages with the thread on the surface of the bottle cap, thereby driving the bottle cap to start rotating. During the rotation, the bottle cap contacts the blade 101, thereby completing the cutting.

[0038] After that, the first cylinder 5 descends, thereby driving the bottle cap to descend together. The bottle cap is now completely separated from the cylinder 3, and then the third cylinder 11 is turned on to drive the push plate 12 to quickly push the bottle cap onto the conveyor belt 13. The conveyor belt 13 drives the bottle cap to leave, and then the next bottle cap falls on the inner support block 6, entering the next cycle.

[0039] To sum up, the ring cutting device for the production and processing of plastic bottle caps can effectively clamp the bottle caps by setting up upper and lower integrated clamping mechanisms. Specifically, the clamping mechanism includes a liftable inner support assembly at the bottom, which can press the bottle caps from the inside to prevent the bottle caps from sinking inward when subjected to force. It also includes a clamping assembly at the top, which applies downward pressure to press against the outside of the bottle cap, thereby ensuring that the bottle cap does not jump up and down when cutting the ring, thereby improving the ring cutting accuracy.
