Description

Technical Field

[0001] This utility model relates to the field of bottle cap processing technology, and in particular to a rotary wire breaking and padding integrated machine. Background Technology

[0002] The processing of aluminum bottle caps involves three steps: knurling, adding gaskets, and inspection. Inspection is to ensure that the bottle caps are free of defects after knurling and adding gaskets.

[0003] However, these three processes are currently performed by three separate sets of equipment, leading to the following series of problems:

[0004] 1. Low integration: The lack of effective integration between various processes makes continuous assembly line production impossible. This not only increases the complexity of production management but may also lead to production bottlenecks and affect overall production efficiency.

[0005] 2. Large equipment footprint: The three independent sets of equipment each occupy a large space, making the factory layout less compact and wasting valuable production space resources;

[0006] 3. Inconsistent processing: Due to insufficient coordination between various processes, there may be stagnation and waiting during material transfer, which leads to a longer production cycle and increased production costs;

[0007] 4. Limited efficiency improvement: The existing production model is difficult to achieve efficient and continuous production, which limits the further improvement of production capacity and makes it difficult to meet the market demand for high-quality and high-volume bottle caps.

[0008] Currently, bottle cap manufacturers are committed to the research and development of integrated production equipment, aiming to integrate the three processes of knurling, padding, and inspection into a single machine to achieve seamless connection of the production process and improve production efficiency. Based on this, this case is proposed. Utility Model Content

[0044] The advantages of this utility model are:

[0045] 1. By setting up a padding transition plate and a detection transition plate, and optimizing the structure of the padding transition plate, detection transition plate, knurling guide plate, and padding guide plate, each of these plates includes an upper plate and a lower plate. This allows for the installation of a guide plate between the upper and lower plates, enabling the bottle cap to be introduced from one plate to another. This integrates the three processes of knurling, padding, and detection into the same equipment, achieving seamless connection of the production process and improving production efficiency.

[0046] 2. In view of the shortcomings of existing wire breaking and knurling equipment, such as large size, few workstations, and low bottle cap processing efficiency, and to prevent the overall machine from becoming too bulky after integration, this application has made significant improvements to the wire breaking and knurling equipment. Based on undulating ring track guidance, the rotating wire breaking gear and the main shaft of the wire breaking and knurling equipment work together with equally divided turntables to realize automated continuous operation of 8 workstations for feeding, wire breaking and knurling, bottle cap feeding and unloading, which greatly improves the efficiency of wire breaking and knurling, increases the integration of the equipment, reduces the size of the equipment, and achieves the purpose of cost reduction and efficiency improvement.

[0047] 3. To address the shortcomings of existing padding equipment, such as large size, few workstations, and low bottle cap processing efficiency, and to prevent the overall machine from becoming too bulky after integration, this application significantly improves the padding equipment. Based on undulating circular track guidance, the padding main shaft, in conjunction with equally divided turntables, achieves automated continuous operation of 8 workstations for pad feeding, bottle cap feeding, padding, and unloading, greatly improving padding efficiency, increasing equipment integration, reducing equipment size, and achieving cost reduction and efficiency improvement. 4. This application improves the pad feeding device. Due to the design requirements of the rotary wire breaking and padding integrated machine, the pad feeding device's pad sorting section outlet cannot be directly connected to the pad conveyor belt. Therefore, a pneumatic pad conveying unit is added between the two as a transition. Utilizing the thrust of the front and rear pads during pad discharge, supplemented by the wind power generated by the oblique air outlet, the pads move forward in an orderly manner, allowing them to enter the pad conveyor belt in an orderly manner, meeting the design requirements of the rotary wire breaking and padding integrated machine. The additional transition stroke also ensures the distance between the front and rear pads.

[0048] 5. The detection unit was improved by relying on the design of the transition detection plate, so that it can meet the design requirements of the rotary breaking and padding integrated machine and complete the functions of rejecting defective bottle caps and unloading finished products.

[0086] It should be noted that both the padding transition plate 6 and the detection transition plate 7 have a rotating shaft at their center. The rotating shaft is mounted on the base plate 8 below. Power is input through the rotating shaft to drive the padding transition plate 6 and the detection transition plate 7 to rotate.

[0087] like Figures 2 to 5 As shown, the feeding device includes a bottle cap feeding device 1, which includes a frame. A bottle cap hopper 101, a bottle cap vibrating plate 102, and a cap sorting section are mounted and fixed on the frame. The bottle cap hopper 101 is located at the top, allowing workers to pour unprocessed bottle caps into it. The bottle cap vibrating plate 102 is installed directly below the bottle cap hopper 101 to receive bottle caps output from it. The cap sorting section includes a cap sorting disc 103, a cap sorting section housing 104, and a cap sorting drive unit (i.e., a motor) for driving the cap sorting disc 103 to rotate. The cap sorting disc 103 is disc-shaped and has several bottle cap receiving slots 105 circumferentially arranged. The side of the cap sorting section housing 104 has an inlet 106 and an outlet 107, as shown... Figure 5 As shown, the bottom surface is provided with an air blowing port 108 for blowing air into the cap receiving groove 105. The output end of the cap vibrating plate 102 is connected to the input port 106 of the cap sorting part housing 104, and the output port 107 of the cap sorting plate 103 housing is used to output the bottle cap to the knurling device 2.

[0088] In the bottle cap feeding device 1, the bottle cap operation process is as follows: bottle caps enter the bottle cap vibrating plate 102 from the bottle cap hopper 101, and are output to the cap sorting plate 103 through the bottle cap vibrating plate 102. Due to its unique structural design, the cap sorting plate 103 can only accept bottle caps with their openings facing upwards or downwards into the bottle cap receiving groove 105. The cap sorting plate 103 rotates, and under the action of centrifugal force, it sends the bottle caps out of the output port 107. The design of the air blowing port 108 allows bottle caps with their openings facing downwards to be blown out of the bottle cap receiving groove 105, thereby ensuring that the bottle caps output from the cap sorting part are all neatly arranged with their openings facing upwards, which is convenient for subsequent knurling, ribbing, and padding processes.

[0089] like Figures 6 to 14 As shown, the knurling device 2 includes a base plate 8, a cap feeding conveyor unit 201, a cap feeding dial unit 202, and a knurling unit 203. One end of the cap feeding conveyor unit 201 is connected to the output end of the cap feeding device 1, and the other end is connected to the input end of the cap feeding dial unit 202. The output end of the cap feeding dial unit 202 is connected to the input end of the knurling unit 203, and the output end of the knurling unit 203 is connected to the input end of the padding transition plate 6.

[0090] like Figures 7 to 9 As shown, the cap feeding dial unit 202 includes a cap feeding dial shaft 2021 mounted on the base plate 8, a cap feeding dial 2022 fixed on the cap feeding dial shaft 2021, and a cap feeding guide plate 2023 fixed on the base plate 8 by a bracket. The cap feeding dial 2022 is divided into an upper plate 20221 and a lower plate 20222, and the upper plate 20221 and the lower plate 20222 are provided with corresponding cap receiving grooves 20223 in the circumferential direction. The caps output by the cap feeding conveyor belt unit 201 enter the cap receiving grooves 20223 of the cap feeding dial 2022. One end of the cap feeding guide plate 2023 extends between the upper plate 20221 and the lower plate 20222 of the cap feeding dial 2022, and the other end extends to the circumferential direction of the knurling guide plate 2035, for guiding the caps on the cap feeding dial 2022 into the knurling guide plate 2035.

[0091] like Figures 10 to 14 As shown, the knurling unit 203 includes a knurling main shaft 2031 mounted on the base plate 8. The knurling main shaft 2031 is provided with a fixed toothed disc 2032, a knurling dividing disc 2033, a knurling fixing disc 2034, a knurling guide disc 2035, a top cover disc 2036, and a knurling annular track 2037 from top to bottom.

[0092] The fixed gear disc 2032 is connected to the main knurling shaft 2031 via bearings and is fixed to the base plate 8 via a bracket. The fixed gear disc 2032 has external teeth on its circumference. The knurling dividing disc 2033 is fixed to the main knurling shaft 2031. Several dividing shafts 20331 are mounted on the dividing disc 2033 via bearings. The upper end of each dividing shaft 20331 has a rotating knurling gear 20332 that meshes with the fixed gear disc 2032, and the lower end extends to the circumference of the knurling fixed disc 2034, and has knurling teeth 20333 and knurling grooves 20334. The knurling fixed disc 2034 is connected to the main knurling shaft 2031 via bearings and is fixed to the base plate 8 via a bracket. The knurling fixed disc 2034 has a knurling mold 20341 on its circumference, such as... Figure 14 As shown, the knurling die 20341 is provided with a knurling tooth plate 20342 that cooperates with the knurling teeth 20333 and a knurling blade 20343 that cooperates with the knurling groove 20334.

[0093] The knurling guide plate 2035 is fixed on the knurling main shaft 2031.

[0094] The top cover turntable 2036 is fixed on the knurling main rotating shaft 2031. The top cover turntable 2036 is provided with several bottle cap top rod 20363 assemblies and has several through holes 20361. The bottle cap top rod 20363 assembly includes a guide rod 20362, a bottle cap top rod 20363 and a double hole connecting plate 20364. The bottle cap top rod 20363, the through holes 20361 on the top cover turntable 2036, the bottle cap receiving groove 20353 on the knurling guide plate 2035 and the equally divided rotating shaft 20331 are all in one-to-one correspondence, and the corresponding components are arranged coaxially. The guide rod 20362 is located between the top cover turntable 2036 and the knurled annular track 2037, and the upper end of the guide rod 20362 is fixed to the bottom surface of the top cover turntable 2036. The lower end of the bottle cap top rod 20363 is provided with a track wheel 20365 that travels on the knurled annular track 2037, and the upper end is equipped with a top cover rotating head 20366 through a bearing. One hole of the double-hole connecting plate 20364 is slidably connected to the guide rod 20362 through a linear bearing, and the other hole is fixedly connected to the bottle cap top rod 20363.

[0095] The knurling ring track 2037 is set around the knurling main shaft 2031 and fixed on the base plate 8. The knurling ring track 2037 is set up with up and down undulations.

[0096] The processing of the knurling unit 203 is as follows: The bottle cap enters the bottle cap receiving groove 20353 of the knurling guide plate 2035 through the cap feeding dial 2022; the knurling main rotating shaft 2031 drives the knurling equal-division rotating disk 2033, the knurling guide plate 2035, and the top cap rotating disk 2036 to rotate, thereby causing the equal-division rotating shaft 20331 and the bottle cap top rod 20363 assembly to rotate around the knurling main rotating shaft 2031; during this process, the rotating knurling gear 20332 at the upper end of the equal-division rotating shaft 20331 rotates due to meshing with the fixed gear plate 2032, thereby driving the equal-division rotating shaft 20331 to rotate around its own central axis; during the rotation of the bottle cap top rod 20363 assembly around the axis, due to the lower knurling annular track 2037... The influence of the guide rod 20362 causes the cap push rod 20363 to rise and fall vertically. When the cap push rod 20363 rises, the upper end of the rotating head 20366 passes through the through hole 20361 and lifts the cap in the cap receiving groove 20353 (the cap opening faces upward), so that the cap fits into the lower end of the equal-division rotating shaft 20331. When the equal-division rotating shaft 20331 with the cap fits passes through the knurling mold 20341, the knurling teeth 20333 and the knurling tooth plate 20342 cooperate to achieve the knurling of the cap. The knurling groove 20334 and the knurling blade 20343 cooperate to achieve the knurling of the cap. When the cap push rod 20363 falls, the cap falls with the cap push rod 20363 and returns to the cap receiving groove 20353. Then it enters the padding transition plate 6 through the knurling guide plate 604.

[0097] The design of the cap rotating head 20366 ensures that when the equally spaced rotating shaft 20331 rotates around its central axis, the cap that has been lifted and fitted can also rotate smoothly. Preferably, the cap lifting rod 20363 and the cap rotating head 20366 are provided with a through suction channel 20367. The lower end of the suction channel 20367 can be connected to a suction device through a pipe, and the upper end is used to hold the cap on the knurled guide plate 2035 tightly. When the cap is lifted or lowered, the cap rotating head 20366 continuously holds the cap through the suction channel 20367 to prevent the cap from falling off.

[0098] like Figures 15 to 21As shown, the feeding device includes a gasket feeding device 3, which includes a gasket hopper 301, a gasket vibrating plate 302, and a gasket sorting section. The gasket sorting section includes sorting blades 303, a gasket sorting section housing 304, and a blade drive unit for driving the sorting blades 303 to rotate. The side of the gasket sorting section housing 304 is provided with an inlet 305 and an outlet 306. The outlet end of the gasket hopper 301 is connected to the inlet end of the gasket vibrating plate 302, and the outlet end of the gasket vibrating plate 302 is connected to the inlet 305 of the gasket sorting section housing 304. The outlet 306 of the gasket sorting plate housing is used to output gaskets. The gasket hopper 301 is located at the top, allowing workers to pour gaskets into it. The gasket vibrating plate 302 is installed directly below the bottle cap hopper 101 to receive gaskets output from the gasket hopper 301 and output them to the gasket sorting section. Figure 17 As shown, the pad-feeding blades 303 inside the pad-feeding section rotate to eject the pads out of the output port 306.

[0099] Gasket feeding device 3 includes a gasket conveyor belt unit, such as Figure 16 , Figure 17 and Figure 21 As shown, the gasket conveyor belt unit includes a gasket conveyor belt 307, a gasket removal mechanism, and a negative pressure adsorption mechanism. One end of the gasket conveyor belt 307 is used to receive the gaskets output from the gasket receiving housing 304, and the other end is used to connect to the gasket adding device 4. The gasket conveyor belt 307 has suction holes on its surface. The negative pressure adsorption mechanism includes a suction box 308 and a suction unit 309 (such as a blower). The side of the suction box 308 has an air outlet for connecting to the suction unit 309, and the top surface of the suction box 308 has an air intake. The suction box 308 is positioned between the upper and lower belts of the gasket conveyor belt 307 and is in close contact with the upper belt, thus adsorbing the gaskets on the gasket conveyor belt 307 and preventing gasket displacement.

[0100] The reverse pad removal mechanism includes a reverse pad detection sensor 310, a recovery pipe 311, and a high-frequency air blowing valve 312 for reverse pad removal. The reverse pad detection sensor 310 is used to detect whether the pad orientation is correct (the pads are marked on the front before being introduced into the pad hopper 301; the sensor determines whether the pad orientation is correct by detecting whether there is a mark on the front). One end of the recovery pipe 311 is close to one side of the pad conveyor belt 307, and the other end enters the pad sorting section housing 304. The high-frequency air blowing valve 312 for reverse pad removal (connected to a high-pressure air pump; the force of the air sprayed here is much greater than the adsorption force of the negative pressure adsorption mechanism) is located on the other side of the pad conveyor belt 307 and directly opposite one end of the recovery pipe 311. When the reverse pad detection sensor 310 detects a reverse pad, the high-frequency air blowing valve 312 sprays air, spraying the pad back into the pad sorting section housing 304 through the recovery pipe 311.

[0101] Due to the design requirements of the rotary wire breaking and padding integrated machine, the outlet of the pad feeding device 3 and the pad conveyor belt 307 cannot be directly connected. Therefore, in this embodiment, a pneumatic pad conveying unit is added between the two as a transition. Utilizing the thrust of the front and rear pads during discharge, supplemented by the wind power generated by the oblique airflow, the orderly forward movement of the pads is achieved, allowing them to enter the pad conveyor belt 307 in an orderly manner. This meets the design requirements of the rotary wire breaking and padding integrated machine, and the additional transition stroke also ensures the distance between the front and rear pads. Figures 17 to 20 As shown, the gasket pneumatic conveying unit includes a feeding air blowing section 313 (such as a blower), a pneumatic conveying box 314, a feeding plate 315, and a limiting rod 316. The side of the pneumatic conveying box 314 has an air inlet for connecting to the feeding air blowing section 313, and the top surface of the pneumatic conveying box 314 has an air outlet. The feeding plate 315 covers the top surface of the pneumatic conveying box 314, and the surface of the feeding plate 315 has multiple semi-conical air guide channels 3151 along its length direction. The air guide channel 3151 corresponds to the air outlet. The air guide channel 3151 is set on the bottom surface of the feeding plate 315. The air enters from one end of the air guide channel 3151, passes through the air guide channel 3151, and is blown out obliquely from the air outlet. One end of the feeding plate 315 extends to the output port 306 of the pad tray shell, and the other end extends to the pad conveyor belt 307. The limiting rod 316 is set above the feeding plate 315 to limit the height of the pads blown by the wind.

[0102] The padding device 4 includes a base plate 8, a padding dial unit 401, and a padding unit 402.

[0103] like Figure 22 and Figure 23 As shown, the pad feeding dial unit 401 includes a pad feeding dial shaft 4011 mounted on the base plate 8, a pad feeding dial 4012 fixed on the pad feeding dial shaft 4011, a pad guide plate 4013 fixed on the base plate 8 by a bracket, and a pad straightening plate 4014 fixed on the base plate 8 by a bracket. The pad adding unit 402 includes a pad adding equal division turntable 4022, and a pad limiting groove plate 40221 is fixed on the pad adding equal division turntable. The pad limiting groove plate 40221 has a notch that can just accommodate one pad. The circumferential direction of the pad feeding dial 4012 is provided with a pad receiving groove 40121 for receiving the pads output from the pad conveyor belt 307 unit. One end of the pad guide plate 4013 extends to the circumferential direction of the pad feeding dial 4012, and the other end extends to the notch side of the pad limiting groove plate 40221 for guiding the pads in the pad feeding dial 4012 to the pad dividing turntable 4022. The pad straightening plate 4014 is used to completely push the pads entering the pad dividing turntable 4022 into the notch of the pad limiting groove plate 40221.

[0104] like Figure 24 and Figure 25As shown, the padding unit 402 includes a padding main rotating shaft 4021 mounted on the base plate 8. From top to bottom, the padding main rotating shaft 4021 is provided with the padding dividing turntable 4022, the padding guide plate 4023, the padding tray 4024, and the padding annular track 4025. The padding annular track 4025 is arranged around the padding main rotating shaft 4021 and fixed to the base plate 8, and the padding annular track 4025 is arranged in an undulating manner. The padding tray 4024 is fixedly connected to the padding guide plate 4023 by bolts, and the padding guide plate 4023 is fixed to the padding main rotating shaft 4021. The shimming and dividing turntable 4022 is also fixed to the shimming main rotating shaft 4021 (in actual design, the shimming tray 4024, the shimming and dividing turntable 4022, and the shimming guide plate 4023 are fixed together with bolts, and then the shimming guide plate 4023 is fixed to the shimming main rotating shaft 4021). The shimming and dividing turntable 4022 is provided with a shimming top rod 4026, a shimming guide post 4027, a shimming guide rod 4028, and a three-hole connecting plate 4029. One hole on one side of the three-hole connecting plate 4029 is slidably connected to the shimming guide rod 4028 through a linear bearing, and the other two holes are fixedly connected to the shimming top rod 4026 and the shimming guide post 4027, respectively. The lower end of the shimming guide rod 4028 is fixed to the top surface of the shimming and dividing turntable 4022, and the shimming guide post 4027 penetrates the shimming and dividing turntable 4022 from top to bottom. 22. A padding guide plate 4023 and a padding tray 4024 are provided, with a track wheel 4030 at the bottom that travels on a padding annular track 4025. The padding dividing turntable 4022 has a through hole 40222 located exactly below the notch of the padding limiting groove plate 40221. The padding top rod 4026, the notch of the padding limiting groove plate 40221, the through hole 40222 on the padding dividing turntable 4022, and the bottle cap receiving groove 40233 on the padding guide plate 4023 correspond one-to-one, and the corresponding components are coaxially arranged. The padding top rod 4026 has a through suction channel 40261. The upper end of the suction channel 40261 can be connected to a suction device through a pipe, and the lower end is used to adsorb the pad that enters the notch of the padding limiting groove plate 40221.

[0105] The processing flow of the padding unit 402 is as follows: When the pad enters the vicinity of the notch in the pad limiting groove 40221 of the padding equal division turntable 4022 through the padding guide plate 4013, it is attracted by the padding top rod 4026 above. When the padding equal division turntable 4022 rotates at a certain angle, the attracted pad is completely pushed into the notch in the pad limiting groove 40221 by the padding straightening plate 4014. The bottle cap with broken knurling completed enters the bottle cap receiving groove 40233 of the padding guide plate 4023 through the padding guide plate 605 on the padding transition plate 6. When the padding equal division turntable 4022 rotates, the padding top rod 4026 also rotates around the padding main rotating shaft 4021, and the track wheel 4030 below it is on the padding annular track 4025. The padding mechanism is designed with undulating circular track 4025, allowing padding rod 4026 to rise and fall along padding guide rod 4028. When padding rod 4026 falls, it pushes the adsorbed pad into the cap in cap receiving groove 40233 below, completing the padding. Padding tray 4024 is designed to provide support for the cap and prevent it from falling out of cap receiving groove after padding rod 4026 is pressed down. When padding rod 4026 rises, suction channel 40261 stops suction, the pad is left inside the cap, and padding rod 4026 resets for the next round of operation. The padded cap enters detection transition plate 7 via detection guide plate 704 and padding guide plate 4023.

[0106] like Figure 26 As shown, the detection unit 5 includes a pre-detection part and a post-detection part.

[0107] The pre-detection section includes a first detection sensor 501, a second detection sensor 502, and a first-stage rejection unit arranged sequentially along the rotation direction of the detection transition plate 7. The first detection sensor 501 is used to detect whether the bottle cap has a gasket, and the second detection sensor 502 is used to detect whether there are defects on the top surface and inside of the bottle cap. If either the first detection sensor 501 or the second detection sensor 502 detects a defect, the bottle cap is determined to be a defective product. The first-stage rejection unit includes a position adjustment mechanism 503, a high-frequency air blowing valve 504 for defective products mounted on the position adjustment mechanism 503, and a defective product hopper 505. The adjustment mechanism is used to adjust the blowing angle of the high-frequency air blowing valve 504 for defective products, and the high-frequency air blowing valve 504 for defective products is used to blow the defective bottle caps in the detection transition plate 7 into the defective product hopper 505.

[0108] The subsequent inspection section includes a feeding conveyor belt 506, a third detection sensor 507 positioned above the feeding conveyor belt 506, a second defective product hopper 508 positioned on one side of the feeding conveyor belt 506, and a second high-frequency air blowing valve 509 for defective products positioned on the other side of the feeding conveyor belt 506. The other end of the detection guide plate 705 extends to one end of the feeding conveyor belt 506 and is used to introduce bottle caps on the detection transition plate 7 into the feeding conveyor belt 506. The third detection sensor 507 is used to detect whether there are defects on the side of the bottle caps. The second high-frequency air blowing valve 509 for defective products is used to blow defective bottle caps on the feeding conveyor belt 506 into the second defective product hopper 508.

[0109] Bottle caps entering the inspection transition plate 7 are inspected by the first inspection sensor 501 and the second inspection sensor 502. If they are defective, they will be blown into the defective product discharge hopper 1 505. Good products enter the discharge conveyor belt 506 through the inspection guide plate 705. After being inspected by the third inspection sensor 507, if there are any defective products, they will be blown into the defective product discharge hopper 2 508. Good products will then be discharged normally and enter the packaging process.

[0110] like Figure 27 As shown, the position adjustment mechanism 503 includes an angle adjustment block 5031, a first linear adjustment rod 5032, a double-headed clamp 5034, and a second linear adjustment rod 5033. The angle adjustment block 5031 has a mounting hole and a screw threaded into it for screwing in. One end of the first linear adjustment rod 5032 is fixedly connected to the angle adjustment block 5031, and one end of the second linear adjustment rod 5033 is fixedly connected to a first high-frequency air blowing valve 504 for defective products. The two clamping portions of the double-headed clamp 5034 are respectively clamped and fixed to the other ends of the first and second linear adjustment rods 5032 and 5033, respectively, with the first and second linear adjustment rods perpendicular to each other. Through the position adjustment mechanism 503, the air jet angle and the jet distance between the first high-frequency air blowing valve 504 and the bottle cap can be adjusted, thereby adapting to the detection of bottle caps of different sizes.

[0111] Preferably, the equipment in this embodiment can also be equipped with lamps (not shown in the figure). The lamps can be installed on the equipment frame via lamp rails, which facilitates worker operation or maintenance of the equipment.

[0112] In this embodiment, the power for various rotating shafts can be transmitted and input via a motor installed below the base plate 8 and gear transmission.

[0113] The above embodiments are only used to explain the concept of this utility model, and are not intended to limit the protection of this utility model. Any non-substantial modifications made to this utility model using this concept should fall within the protection scope of this utility model.
