Description

TECHNICAL FIELD

[0001] The application belongs to the field of mechanical processing equipment, and particularly relates to a cutting device for circumferential point distribution plastic bottle cap anti-theft ring. BACKGROUND

[0002] In the production process of plastic bottle caps, the anti-theft ring structure, as an important component, usually needs to be formed into a specific breakpoint or opening through a cutting process. Such cutting operations not only require high precision and consistency, but also need to have high-efficiency automated production capacity to meet the dual demands of product quality and production efficiency in the modern packaging industry.

[0003] For example, a bottle cap production equipment in Chinese patent application No. CN202321546040.7 includes a workbench, a rotating disc, a feeding mechanism, and a ring cutting knife. The side wall of the rotating disc is provided with an extension part, the extension part is provided with a fixed rod that can be switched between a first state and a second state, and an elastic member that can switch the fixed rod from the second state to the first state. The fixed rod is longitudinally arranged and located on the outer side of the ring cutting knife. The feeding mechanism includes a feeding track, and the side wall of the feeding track is provided with a discharge port for moving the bottle cap onto the workbench. The upstream side of the feeding track is connected with a lifting rail, and the lifting rail is provided with a gradually rising lifting slope along the rotating direction of the rotating disc. The fixed rod is pushed upward to the second state by sliding to the lifting slope, and the fixed rod is inserted into the bottle cap to the first state by disengaging from the lifting slope. The bottle cap is placed inside the feeding track to prevent the bottle cap from moving, and then the state of the fixed rod is adjusted to accurately insert the fixed rod into the bottle cap, thereby improving the efficiency of the bottle cap ring cutting.

[0004] The bottle cap production equipment in the prior art, such as the above-mentioned, can complete the cutting process of the bottle cap anti-theft ring, but still has some deficiencies in actual use.

[0005] Firstly, manual or fixed rod can easily cause displacement of the bottle cap during the cutting process, resulting in uneven cuts or even waste products, especially for the requirement of fine cutting of circumferential point distribution.

[0006] Secondly, the cutting, discharging, and debris cleaning steps are separated, and manual intervention is required to transfer the workpiece or clean the debris, resulting in low production efficiency and easy pollution of the finished product. For example, plastic debris generated during cutting can be easily retained in the clamp or inside the bottle cap, which not only affects the subsequent cutting precision, but also may mix into the finished product to cause quality defects.

[0007] Thirdly, the existing equipment cannot simultaneously realize the combined motion of revolution and rotation of the bottle cap, resulting in poor uniformity of circumferential cutting. Moreover, the cutting height adjustment is complicated and cannot quickly adapt to different specifications of bottle caps. SUMMARY

[0052] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0053] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the concept of the present application, therefore the present application is not limited to the specific embodiments disclosed below.

[0054] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In a preferred embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is separate or alternative to other embodiments.

[0055] Thirdly, the present application is described in detail in conjunction with the schematic diagram, and in the detailed description of the embodiments of the present application, the cross-sectional view of the device structure is partially enlarged without general proportion for the convenience of description, and the schematic diagram is only an example, which should not limit the scope of protection of the present application herein. In addition, three-dimensional spatial dimensions including length, width and depth should be included in actual manufacture.

[0056] Please refer to the accompanying Figures 1 to 4 As shown in the accompanying drawings, the embodiment provides a circumferential point-like distribution plastic bottle cap anti-theft ring cutting device, which comprises a workbench 1, and a half-tooth ring 9 is fixedly connected to the top surface of the workbench 1 by a support rod;

[0057] A driving mechanism 2 is arranged at the lower end of the workbench 1 for providing power;

[0058] The rotating disc 3 is fixedly installed on the driving mechanism 2.

[0059] The auxiliary mechanism 4 is arranged on the rotating disc 3 in a ring shape.

[0060] The feeding mechanism 5 is arranged on the workbench 1 and is used for feeding.

[0061] The cutting mechanism 6 is arranged on the top surface of the workbench 1 and cooperates with the driving mechanism 2 and the auxiliary mechanism 4 to perform cutting work.

[0062] The screening mechanism 7 is arranged on the bottom surface of the workbench 1.

[0063] The boss 8 is fixedly connected to the top surface of the workbench 1.

[0064] The auxiliary mechanism 4 includes a shell group 41, which is fixedly connected to the rotating disc 3. The lower end of the shell group 41 is provided with a fixed part 42. The shell group 41 is provided with a discharging part 43. The lower end of the shell group 41 is further provided with a residue discharging part 44.

[0065] In this embodiment, the fixed part 42 adopts an elastic clamping structure, which realizes stable fixing of the plastic bottle cap through elastic claws, so as to ensure that the bottle cap does not displace during cutting. The discharging part 43 is used to automatically guide the finished product bottle cap to slide out to the collection area after cutting is completed. The residue discharging part 44 discharges the plastic scraps generated during cutting to the screening mechanism 7 below for processing, so as to ensure continuous and efficient operation of the device. The driving mechanism 2 drives the rotating disc 3 to rotate, so that the auxiliary mechanism 4 moves, and the cutter of the cutting mechanism 6 performs accurate cutting. After the feeding mechanism 5 sequentially sends the bottle cap into the auxiliary mechanism 4, the whole cutting, discharging and residue discharging process is completed in a cycle under the synchronous control of the driving mechanism 2, so as to improve the production automation degree and cutting precision.

[0066] It should be noted that the feeding mechanism 5 is used to orderly transport the bottle cap to a preset position. The currently publicly available feeding equipment is adopted. When selecting the type, the specification and use scene should be suitable, and the type that meets the needs of the application should be selected as much as possible. The specific type and specification are not limited here.

[0067] Secondly, please refer to Figure 9 and Figure 10 The driving mechanism 2 includes a motor 21, which is fixedly installed at the lower end of the workbench 1. The output shaft of the motor 21 is fixedly connected with a driving rod 22, and the driving rod 22 is fixedly connected with the rotating disc 3. The first bevel gear 23 and the second bevel gear 24 are fixedly installed on the driving rod 22.

[0068] In this embodiment, the motor 21 is started to drive the drive rod 22 to rotate, and then the first bevel gear 23 and the second bevel gear 24 are rotated; at the same time, the rotation of the drive rod 22 also drives the two rotating discs 3 to rotate, and the rotation of the rotating discs 3 drives the auxiliary mechanism 4 to rotate along the axis of the drive rod 22.

[0069] Thirdly, please refer to Figures 3 to 6 , the shell group 41 comprises a first cylinder 412, the first cylinder 412 is slidingly inserted into the upper rotating disc 3, the upper end of the first cylinder 412 is fixedly connected with a mounting seat 411, the lower end of the first cylinder 412 is rotatably connected with a second cylinder 413, and the second cylinder 413 is slidingly connected with the lower rotating disc 3, the outer wall of the upper end of the first cylinder 412 is fixedly sleeved with a guide ring 414, the first tension spring 415 is fixedly connected between the guide ring 414 and the upper rotating disc 3, the top surface of the upper rotating disc 3 is further fixedly connected with a guide rod 416, and the guide rod 416 is slidingly connected with the guide ring 414, the lower end outer wall of the second cylinder 413 is fixedly installed with a transmission gear 417, and the lower end of the second cylinder 413 is threadedly connected with a threaded sleeve 418.

[0070] Secondly, please refer to Figure 6 , the fixed part 42 comprises a compression spring 421, the compression spring 421 is fixedly connected to the outer wall of the threaded sleeve 418 in a ring shape, the other end of the compression spring 421 is fixedly connected with a support block 422, the support block 422 is provided with a cavity 423, and the cavity 423 is provided with a plurality of air outlet holes 424 arranged in an array.

[0071] In this embodiment, when the auxiliary mechanism 4 rotates to the position of the boss 8, the boss 8 contacts the first cylinder 412, the second cylinder 413 and the mounting seat 411, causing the above-mentioned components to move upward and exert a stretching force on the first tension spring 415; with further rotation of the auxiliary mechanism 4, once the contact with the boss 8 is lost, the restoring force of the first tension spring 415 will cause the first cylinder 412, the second cylinder 413 and the mounting seat 411 to quickly return to their original positions, so that the fixed part 42 is inserted into the bottle cap, thereby achieving the fixation of the bottle cap.

[0072] Specifically, the plurality of support blocks 422 on the threaded sleeve 418 will quickly descend, and because the lower end of the support block 422 is smaller and the upper end is larger, the lower end is first inserted into the bottle cap, and then the plurality of support blocks 422 are close to each other and compress the compression spring 421 due to the resistance of the bottle cap. The compression spring 421 then exerts a counteracting force to push the support blocks 422 away from each other, thereby achieving the fixation of the bottle cap.

[0073] It is worth noting that the support block 422 is provided with a cutting groove to avoid rigid contact between the cutting tool and the support block 422, and the threaded sleeve 418 is connected with the second cylinder 413 through threads, and by rotating the threaded sleeve 418, the second cylinder 413 can be lifted at the lower end, so as to adjust the height of the cutting groove according to different cutting requirements.

[0074] With the rotation of the auxiliary mechanism 4 driving the bottle cap along the axis of the drive rod 22, when the transmission gear 417 on the second cylinder 413 rotates to the position of the half-toothed ring 9, the transmission gear 417 meshes with the half-toothed ring 9 to drive the second cylinder 413 to rotate, so that the bottle cap revolves along the axis of the drive rod 22 while also rotates along the axis of the second cylinder 413, thereby realizing uniform and continuous cutting on the bottle cap, ensuring the neatness and beauty of the cut opening.

[0075] Please refer again to Figures 3 to 6 , the blanking part 43 includes a bevel gear ring 431, which is fixedly connected to the workbench 1 by a support rod, the inner cavity of the mounting seat 411 is rotatably connected with a round rod 432 through a bearing, the round rod 432 is fixedly sleeved with a winding roller 433, one end of the round rod 432 is fixedly connected with a third bevel gear 434, the inner wall of the second cylinder 413 is slidably connected with a piston plate 435, the bottom surface of the piston plate 435 is fixedly connected with a push rod 436, and the push rod 436 is pistonically inserted into the second cylinder 413, the bottom surface of the piston plate 435 is fixedly connected with a second tension spring 437, and the lower end of the second tension spring 437 is fixedly connected with the inner wall of the second cylinder 413, the top surface of the piston plate 435 is rotatably connected with a connecting block 438 through a bearing, the winding roller 433 is connected with a traction rope 439, and the other end of the traction rope 439 is fixedly connected with the connecting block 438.

[0076] In this embodiment, with the continuous rotation of the auxiliary mechanism 4, when the third bevel gear 434 reaches the position of the bevel gear ring 431, the third bevel gear 434 meshes with the bevel gear ring 431 to drive the round rod 432 to rotate. The rotation of the round rod 432 drives the winding roller 433 to rotate to wind the traction rope 439, and at the same time, the connecting block 438, the piston plate 435 and the push rod 436 move upward synchronously, and the second tension spring 437 is stretched.

[0077] With further rotation of the auxiliary mechanism 4, once the meshing of the third bevel gear 434 and the bevel gear ring 431 is released, under the restoring force of the second tension spring 437, the piston plate 435 and the push rod 436 will return to the original position. At the same time, the winding roller 433 performs unwinding operation, and under the rapid elastic rebounding action of the second tension spring 437, the push rod 436 will extend downward by a distance to hit the bottle cap, so that the bottle cap falls off from the fixing part 42.

[0078] Please refer again to Figure 6The slag discharge part 44 comprises a first hollow ring 441 arranged outside the second cylinder 413, a gas delivery pipe 442 is communicated on the first hollow ring 441, the gas delivery pipe 442 is communicated with the inner cavity of the second cylinder 413, the lower end of the first hollow ring 441 is rotatably connected with a second hollow ring 443 through a bearing, the lower end of the second hollow ring 443 is connected with an elastic hose 444, and the lower end of the elastic hose 444 is communicated with the cavity 423 on the support block 422.

[0079] In this embodiment, when the piston plate 435 moves downward, the air in the second cylinder 413 is compressed, and the compressed air enters the first hollow ring 441 through the gas delivery pipe 442 and continues to flow to the second hollow ring 443. Then, the air enters the cavity 423 on the support block 422 through the elastic hose 444 at the lower end of the second hollow ring 443, and finally is discharged through the air outlet hole 424. This process removes the cutting debris adhering to the cutting groove on the support block 422 by blowing gas, so as to prevent the cutting debris from affecting the subsequent cutting operation.

[0080] It should be noted that the first hollow ring 441 and the second hollow ring 443 are rotatably connected, so that the second hollow ring 443 can rotate synchronously when the threaded sleeve 418 is rotated. This design avoids the winding of the elastic hose 444 and ensures the smoothness of gas flow.

[0081] In addition, the connecting block 438 and the piston plate 435 are rotatably connected to adapt to the rotation of the second cylinder 413. This design allows the connecting block 438 and the piston plate 435 to rotate relatively, thereby avoiding excessive twisting of the traction rope 439 and preventing it from breaking.

[0082] Please refer to Figure 7 and Figure 8 The cutting mechanism 6 comprises a support plate 61 fixedly connected to the top surface of the workbench 1, a sliding rod 62 fixedly connected between the support plate 61 and the workbench 1, a sliding block 63 slidably connected to the sliding rod 62, a lower clamping block 64 fixedly connected to the sliding block 63, an upper clamping block 65 connected to the lower clamping block 64 through bolts, a cutting knife 66 fixedly clamped between the lower clamping block 64 and the upper clamping block 65, a rotating rod 67 rotatably connected to the top surface of the workbench 1 and rotatably connected to the support plate 61 at the upper end, a silk block 68 sleeved on the outer wall of the rotating rod 67, and the silk block 68 is fixedly connected to the lower clamping block 64, wherein the outer wall of the rotating rod 67 is provided with a thread matched with the silk block 68, and the rotating rod 67 is threadedly connected with the silk block 68.

[0083] In this embodiment, the upper clamp block 65 is detachably connected to the lower clamp block 64 by bolts, and the cutter 66 is fixed between the two clamp blocks. The two clamp blocks can be disassembled to replace the cutter 66. In addition, rotating the rotating rod 67 can drive the wire block 68 to move, thereby driving the lower clamp block 64 to move up and down. The displacement of the lower clamp block 64 drives the upper clamp block 65 and the cutter 66 to move synchronously, thereby adjusting the height of the cutter 66. When the cutter 66 performs the plastic bottle cap cutting operation, the cutting debris generated will fall into the cutting groove of the support block 422 or the inside of the bottle cap. Subsequently, the blowing mechanism of the slag removal part 44 is started, and compressed air is sprayed from the air outlet hole 424 to timely remove the cutting debris and avoid the influence of the residues on the subsequent cutting precision. At the same time, during the movement of the lower clamp block 64, the sliding block 63 fixedly connected thereto slides along the sliding rod 62, thereby playing a limiting and guiding role and ensuring the stability of the lifting process.

[0084] Please refer again to Figure 9 and Figure 10 , the screening mechanism 7 comprises a feeding box 71 fixedly connected to the bottom surface of the workbench 1, the lower end of the feeding box 71 is fixedly communicated with a screening box 72, the feeding box 71 is rotatably connected with a first rotating shaft 73 through a bearing, the one end of the first rotating shaft 73 located in the feeding box 71 is connected with stirring rods 74 in an array, the other end of the first rotating shaft 73 is fixedly installed with a fourth bevel gear 75, the screening box 72 is hingedly connected with a sieve plate 76, the bottom surface of the sieve plate 76 and the screening box 72 are fixedly connected with springs 77 in an array, the screening box 72 is rotatably connected with a second rotating shaft 78 through a bearing, the one end of the second rotating shaft 78 located in the screening box 72 is fixedly connected with a cam 79, the other end of the second rotating shaft 78 is fixedly installed with a fifth bevel gear 710, wherein the sieve plate 76 is upwardly inclinedly arranged at the end close to the driving mechanism 2.

[0085] In this embodiment, the cut waste and bottle caps are separated from the auxiliary mechanism 4 and fall into the feeding box 71 according to the predetermined process. Under the continuous rotation of the driving rod 22, the first bevel gear 23 and the fourth bevel gear 75 are in meshing transmission, and at the same time, the second bevel gear 24 and the fifth bevel gear 710 are also in meshing transmission. This series of actions ensures the accuracy and efficiency of mechanical transmission.

[0086] Subsequently, the rotation of the first rotating shaft 73 drives the rotation of the stirring rods 74 made of rubber. The stirring rods 74 can flip the bottle caps by hitting them, which effectively promotes the separation of the cutting debris remaining in the bottle caps from the bottle caps. These debris and bottle caps then fall onto the sieve plate 76.

[0087] Meanwhile, the rotation of the second rotating shaft 78 drives the rotation of the cam 79. When the cam 79 rotates to a certain position, it hits the sieve plate 76, causing one end of the sieve plate 76 to flip up and stretch the spring 77. When the cam 79 is no longer in contact with the sieve plate 76, the spring 77 is reset under the action of the reset force, causing the sieve plate 76 to reset. This process is repeated in turn, causing the sieve plate 76 to vibrate continuously.

[0088] The vibration of the sieve plate 76 effectively separates the bottle caps and waste. The cut waste, due to its small size, can pass through the sieve plate 76 and fall to the bottom of the screening box 72, while the bottle caps, due to their large size, are smoothly discharged along one end of the sieve plate 76.

[0089] It should be noted that a discharge port is provided at the lower end of the screening box 72, and a sealing baffle is provided at the discharge port to discharge the debris collected in the screening box 72 (not shown in the figure).

[0090] The working principle of the present application is as follows:

[0091] First, the motor 21 in the driving mechanism 2 is started, driving the driving rod 22 to rotate, thereby synchronously rotating the two rotating discs 3 and causing the multiple auxiliary mechanisms 4 arranged in a ring to revolve around the axis of the driving rod 22. Structures such as the boss 8, the half-toothed ring 9, and the bevel gear 431 are provided in the path of the auxiliary mechanism 4 to achieve automatic clamping of the bottle cap, self-rotation of the bottle cap to achieve uniform cutting, and triggering of the discharging action.

[0092] When the auxiliary mechanism 4 reaches the boss 8 position, the shell group 41 (including the first cylinder 412, the second cylinder 413, and the mounting seat 411) is lifted by the boss 8 and stretches the first tension spring 415. After leaving the boss 8, it quickly falls under the reset force of the first tension spring 415, causing the fixed part 42 to insert into the bottle cap and achieve clamping through the elastic expansion of the compression spring 421 of the support block 422. Subsequently, the transmission gear 417 on the second cylinder 413 engages with the half-toothed ring 9, causing the bottle cap to rotate while revolving, ensuring that the cutting tool can continuously and uniformly cut the anti-theft ring in the circumferential direction.

[0093] The cutting mechanism 6 adjusts the height of the cutting knife 66 by cooperating the wire block 68 with the rotating rod 67, and the sliding block 63 guides the stable lifting along the sliding rod 62 to complete the precise cutting of the bottle cap, and the blowing function of the slag discharge part 44 removes the residual debris to ensure the cutting quality.

[0094] After cutting, the auxiliary mechanism 4 continues to rotate to the bevel gear 431 position, the third bevel gear 434 engages with it to drive the winding roller 433 to rotate, the traction rope 439 pulls the push rod 436 up and quickly hits the bottle cap after release, causing it to fall off from the fixed part 42 into the discharging process. The slag discharge part 44 blows out the debris in the cutting groove of the support block 422 through the air pressure system.

[0095] Finally, the screening mechanism 7 receives the bottle caps and waste falling from above, flips the bottle caps by the stirring rod 74 to promote the separation of debris, and periodically hits the screen plate 76 by the cam 79 to generate vibration, so that the waste falls through the screen plate 76 and falls into the bottom of the screening box 72, and the qualified bottle caps are discharged along the screen plate 76, thereby realizing efficient and automatic integrated cutting and screening operation.

[0096] The above is only the preferred embodiment of the present application, it should be noted that for those skilled in the art, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application. The structure, device and operation method not specifically described and explained in the present application, such as no special description and limitation, are implemented according to the conventional means in the art.
