Description

Technical Field

[0001] The utility model relates to the technical field of bottle cap processing, in particular to a gasket feeding device for a rotary line breaking and gasketing integrated machine. Background Art

[0002] The processing of aluminum bottle caps requires three steps: line breaking, knurling, padding and testing. Figure 1 The figure shows the aluminum bottle cap after breaking the line, knurling and adding padding inside the cap. The test is to ensure that there are no defects in the bottle cap after breaking the line, knurling and adding padding.

[0003] However, these three processes are currently performed by three independent sets of equipment, resulting in the following series of problems:

[0004] 1. Low integration: There is a lack of effective integration between the various processes, making it impossible to achieve continuous production in an assembly line manner. 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 take up a large space, making the factory layout less compact and wasting valuable production space resources;

[0006] 3. Inconsistent processing: Due to the lack of close connection between the various processes, there may be stagnation and waiting during the material transmission process, which will extend the production cycle and increase 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-yield bottle caps.

[0008] At present, all bottle cap manufacturers are committed to the research and development of integrated production equipment, hoping to integrate the three processes of breaking line knurling, padding and testing into the same equipment to achieve seamless connection of production processes and improve production efficiency.

[0009] The applicant is also developing related equipment. In the development of the gasket adding device, the first problem that needs to be solved is the feeding problem of the gasket. Generally speaking, the gasket can be fed in an orderly manner by means of a vibration plate, but the gasket is relatively thin. When it is transported to the processing station on the conveyor belt, it is easy to be affected by the environment and cause displacement, which affects the accuracy of the feeding. At the same time, in order to adapt to the development of the all-in-one machine for breaking line knurling, padding and detection, the existing gasket feeding device also needs to be modified.

[0010] Based on this, this case is brought forward. Utility Model Content

[0011] The purpose of the utility model is to provide a gasket feeding device for a rotary wire breaking and padding all-in-one machine to achieve accurate feeding and at the same time adapt to the design requirements of a wire breaking, knurling, padding and testing all-in-one machine.

[0012] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0013] A gasket feeding device for a rotary line breaking and padding integrated machine comprises a gasket hopper, a gasket vibrating disk, a gasket sorting part and a gasket conveyor belt unit, the gasket sorting part comprises a gasket sorting blade, a gasket sorting part shell and a blade driving part for driving the gasket sorting blade to rotate, the side of the gasket sorting part shell is provided with an input port and an output port, the output end of the gasket hopper is connected with the input end of the gasket vibrating disk, the output end of the gasket vibrating disk is connected with the input port of the gasket sorting part shell, and the output port of the gasket sorting disk shell is used to output the gasket to the gasket conveyor belt unit; the gasket conveyor belt unit comprises a gasket conveyor belt and a negative pressure adsorption mechanism, the belt surface of the gasket conveyor belt is provided with suction holes, the negative pressure adsorption mechanism comprises a wind suction box and a suction part, the side of the wind suction box is provided with an air outlet for connecting to the suction part, the top surface of the wind suction box is provided with an air suction port, the wind suction box is arranged between the upper belt and the lower belt of the gasket conveyor belt, and is in contact with the upper belt.

[0014] Furthermore, the gasket conveyor belt unit includes a back-pad removal mechanism, which includes a back-pad detection sensor, a recovery pipe and a high-frequency blowing valve for the back-pad. The back-pad detection sensor is arranged above the gasket conveyor belt to detect whether the gasket is in the correct orientation. One end of the recovery pipe is adjacent to one side of the gasket conveyor belt, and the other end enters the outer shell of the gasket sorting part. The high-frequency blowing valve for the back-pad is located on the other side of the gasket conveyor belt and is opposite to one end of the recovery pipe.

[0015] Furthermore, it includes a gasket pneumatic conveying unit, which includes a feeding and blowing part, an air delivery box and a feeding plate, the side of the air delivery box is provided with an air inlet for connecting to the feeding and blowing part, the top surface of the air delivery box is provided with an air outlet, the feeding plate is covered on the top surface of the air delivery box, and the plate surface of the feeding plate is provided with a plurality of semi-conical air guide channels and air outlets corresponding to the air guide channels along its length direction, the air guide channel is provided on the bottom surface of the feeding plate, and the air enters from one end of the air guide channel and is blown out obliquely from the air outlet after passing through the air guide channel;

[0016] One end of the feeding plate extends to the output port of the pad arrangement tray shell, and the other end extends to the pad conveyor belt.

[0017] Furthermore, the gasket pneumatic conveying unit includes a limiting rod, which is arranged above the feeding plate and is used to limit the height of the gasket blown up by the wind.

[0018] The advantages of the present invention are:

[0019] 1. By setting an adsorption structure under the conveyor belt, the gasket on the conveyor belt is adsorbed on the conveyor belt to prevent it from deflecting during the conveying process due to the influence of the external environment, thus ensuring the accuracy of gasket loading;

[0020] 2. Due to the design location requirements of the rotary line breaking and padding machine, the outlet of the padding part of the gasket feeding device cannot be directly connected to the gasket conveyor belt, so a gasket pneumatic conveying unit is added between the two as a transition. The thrust of the front and rear gaskets during gasket discharge is utilized, supplemented by the wind force formed by the oblique air outlet, to achieve orderly forward movement of the gaskets, so that the gaskets can enter the gasket conveyor belt in an orderly manner, meeting the design requirements of the rotary line breaking and padding machine. The extra transition stroke can also ensure the distance between the front and rear gaskets. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, a guide structure can be set between (601, 701, 20351, 40231) and the lower plate (602, 702, 20352, 40232) to guide the bottle cap from the previous turntable to the next turntable. The structure is simple, sophisticated and practical, thereby integrating the three processes of line breaking knurling, padding and testing into the same equipment, realizing seamless connection of the production process and improving production efficiency.

[0058] Continue to refer Figure 10The device includes a broken line knurling guide plate 604, a padded guide plate 605, a detection guide plate 704, and a detection guide plate 705. One end of the broken line knurling guide plate 604 extends between the upper plate 20351 and the lower plate 20352 of the broken line knurling guide plate 2035, and the other end extends to the circumference of the padded transition plate 6, for guiding the bottle caps on the broken line knurling guide plate 2035 into the padded transition plate 6; one end of the padded guide plate 605 extends between the upper plate 601 and the lower plate 602 of the padded transition plate, and the other end extends to the circumference of the padded guide plate 4023, for guiding the bottle caps on the padded transition plate 6 into the padded guide plate 4023. One end of the detection introduction plate 704 extends between the upper plate 40231 and the lower plate 40232 of the padded guide plate 4023, and the other end extends to the circumference of the detection transition plate 7, and is used to introduce the bottle caps on the padded guide plate 4023 into the detection transition plate 7; one end of the detection export plate 705 extends between the upper plate 701 and the lower plate 702 of the detection transition plate 7, and the other end extends to the workstation of the next process, and is used to introduce the bottle caps on the detection transition plate 7 into the workstation of the next process.

[0059] It should be noted here that a rotating shaft is set at the center of the padded transition plate 6 and the detection transition plate 7. The rotating shaft is installed on the bottom plate 8 below. Power is input through the rotating shaft to drive the padded transition plate 6 and the detection transition plate 7 to rotate.

[0060] like Figures 3 to 6 As shown, the feeding device includes a bottle cap feeding device 1, which includes a frame, on which a bottle cap hopper 101, a bottle cap vibrating plate 102 and a cap sorting part are fixedly mounted, wherein the bottle cap hopper 101 is located at the top, and workers can pour unprocessed bottle caps into the bottle cap hopper 101, and the bottle cap vibrating plate 102 is installed directly below the bottle cap hopper 101, for receiving the bottle caps output from the bottle cap hopper 101.

[0061] In the bottle cap feeding device 1, the bottle cap operation process is as follows: the 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 allow bottle caps with their openings facing upward or downward to enter the bottle cap receiving groove 105. The cap sorting plate 103 rotates and, under the action of centrifugal force, sends the bottle caps out of the output port 107. The design of the blowing port 108 allows bottle caps with their openings facing downward to be blown out of the bottle cap receiving groove 105, thereby ensuring that the bottle caps output from the cap sorting unit are all neatly arranged with their openings facing upward, facilitating the subsequent knurling, breaking, and padding processes.

[0062] like Figures 7 to 15 As shown, the broken line knurling device 2 includes a base plate 8, a cover feeding conveyor belt unit 201, a cover feeding dial unit 202 and a broken line knurling unit 203, one end of the cover feeding conveyor belt unit 201 is connected to the output end of the bottle cap feeding device 1, and the other end is connected to the input end of the cover feeding dial unit 202, the output end of the cover feeding dial unit 202 is connected to the input end of the broken line knurling unit 203, and the output end of the broken line knurling unit 203 is connected to the input end of the padded transition plate 6.

External teeth are provided on the circumference of the fixed toothed disc 2032. The thread breaking knurling equally divided turntable 2033 is fixed to the main rotating shaft 2031 of the thread breaking knurling. A number of equally divided rotating shafts 20331 are installed on the thread breaking knurling equally divided turntable 20333 through bearings. The upper end of the equally divided rotating shaft 20331 is provided with a rotating thread breaking gear 20332 that meshes with the fixed toothed disc 2032. The lower end extends to the circumference of the thread breaking knurling fixed disc 2034 and is provided with knurled teeth 20333 and thread breaking grooves 20334. The thread breaking knurling fixed disc 2034 is connected to the main rotating shaft 2031 of the thread breaking knurling through a bearing, and is fixed to the bottom plate 8 through a bracket. A thread breaking knurling mold 20341 is provided on the circumference of the thread breaking knurling fixed disc 2034. Figure 15 As shown, the line breaking knurling die 20341 is provided with a knurling tooth plate 20342 that matches the knurling teeth 20333 and a line breaking blade 20343 that matches the line breaking groove 20334.

[0066] The broken line knurling guide disc 2035 is fixed on the broken line knurling main shaft 2031.

[0067] The top cover turntable 2036 is fixed on the broken line knurled main rotating shaft 2031. The top cover turntable 2036 is provided with a plurality of bottle cap push rods 20363 components and a plurality of through holes 20361. The bottle cap push rods 20363 components include a guide rod 20362, a bottle cap push rod 20363 and a double-hole connecting plate 20364. The bottle cap push rods 20363, the through holes 20361 on the top cover turntable 2036, the bottle cap receiving grooves 20353 on the broken line knurled guide plate 2035, and the equally divided rotating shaft 20331 are all in one-to-one correspondence, and the corresponding components are coaxially arranged. The guide rod 20362 is located between the top cover turntable 2036 and the broken line knurled circular 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 runs on the broken line knurled circular track 2037, and the upper end is equipped with a top cover turntable 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.

[0068] The broken line knurled annular track 2037 is arranged around the broken line knurled main shaft 2031 and fixed on the base plate 8. The broken line knurled annular track 2037 is arranged to fluctuate up and down.

[0069] The processing process of the line breaking knurling unit 203 is as follows: the bottle cap enters the bottle cap receiving groove 20353 of the line breaking knurling guide disk 2035 through the cap feeding dial 2022; the line breaking knurling main rotating shaft 2031 drives the line breaking knurling equal-dividing rotating disk 2033, the line breaking knurling guide disk 2035, and the top cover rotating disk 2036 to rotate, thereby causing the equal-dividing rotating shaft 20331 and the bottle cap ejector rod 20363 to rotate around the line breaking knurling main rotating shaft 2031; in this process, the rotating line breaking gear 20332 at the upper end of the equal-dividing rotating shaft 20331 engages with the fixed toothed disk 2032, and the rotating line breaking gear 20332 rotates, thereby driving the equal-dividing rotating shaft 20331 to rotate around its own central axis; during the rotation of the bottle cap ejector rod 20363 assembly around the axis, due to the line breaking knurling annular track 2037 below The influence of 20363 makes the bottle cap push rod 20363 move vertically up and down along the guide rod 20362. When the bottle cap push rod 20363 is raised, the rotating head 20366 at its upper end passes through the through hole 20361, lifts the bottle cap in the bottle cap receiving groove 20353 (the bottle cap opening faces upward), and makes the bottle cap be inserted into the lower end of the equally divided rotating shaft 20331. When the equally divided rotating shaft 20331 with the bottle cap passes through the line breaking knurling die 20341, the knurling teeth 20333 and the knurling tooth plate 20342 cooperate to realize the knurling of the bottle cap, and the line breaking groove 20334 and the line breaking blade 20343 cooperate to realize the line breaking of the bottle cap; when the bottle cap push rod 20363 is lowered, the bottle cap descends along with the bottle cap push rod 20363, returns to the bottle cap receiving groove 20353, and then enters the padded transition plate 6 through the line breaking knurling guide plate 604.

[0070] The arrangement of the bottle cap turret 20366 allows the lifted and inserted bottle cap to rotate smoothly when the equally divided rotating shaft 20331 rotates about its own central axis. Preferably, an air suction channel 20367 is provided through the bottle cap push rod 20363 and the top cover turret 20366. The lower end of the air suction channel 20367 is connected to a suction device via a pipeline, and the upper end is used to tightly suck the bottle cap on the broken line knurled guide plate 2035. When the bottle cap is lifted or lowered, the top cover turret 20366 continuously sucks the bottle cap through the air suction channel 20367 to prevent the bottle cap from dislocating.

[0071] like Figures 16 to 22As shown, the feeding device includes a gasket feeding device 3, which includes a gasket hopper 301, a gasket vibration disk 302 and a gasket sorting part. The gasket sorting part includes a gasket sorting blade 303, a gasket sorting part shell 304 and a blade driving part for driving the gasket sorting blade 303 to rotate. The side of the gasket sorting part shell 304 is provided with an input port 305 and an output port 306. The output end of the gasket hopper 301 is connected with the input end of the gasket vibration disk 302, and the output end of the gasket vibration disk 302 is connected with the input port 305 of the gasket sorting part shell 304. The output port 306 of the gasket sorting disk shell is used to output gaskets. The gasket hopper 301 is located at the top, and workers can pour gaskets into the gasket hopper 301. The gasket vibration disk 302 is installed directly below the bottle cap hopper 101, and is used to receive gaskets output from the gasket hopper 301 and output them to the gasket sorting part, as shown in FIG. Figure 18 As shown, the pad sorting blades 303 in the pad sorting part rotate to knock the pads out of the output port 306.

[0072] The gasket feeding device 3 includes a gasket conveyor belt unit, such as Figure 17 、 Figure 18 and Figure 22 As shown, the gasket conveyor belt unit includes a gasket conveyor belt 307, a back-pad removal mechanism and a negative pressure adsorption mechanism. One end of the gasket conveyor belt 307 is used to receive the gaskets output by the gasket handling portion housing 304, and the other end is used to connect to the padding device 4. The belt surface of the gasket conveyor belt 307 is provided with air suction holes. The negative pressure adsorption mechanism includes a wind suction box 308 and a suction part 309 (such as a blower). The side of the wind suction box 308 is provided with an air outlet for connecting to the suction part 309, and the top surface of the wind suction box 308 is provided with an air suction port. The wind suction box 308 is arranged between the upper belt and the lower belt of the gasket conveyor belt 307 and is in contact with the upper belt. In this way, the gaskets on the gasket conveyor belt 307 can be adsorbed to prevent the gaskets from shifting.

[0073] The anti-pad removal mechanism includes an anti-pad detection sensor 310, a recovery pipe 311 and a high-frequency blowing valve 312 for anti-pad. The anti-pad detection sensor 310 is used to detect whether the gasket is oriented correctly (the gasket has been coded on the front before it is introduced into the gasket hopper 301. Here, the sensor determines whether the gasket is oriented correctly by detecting whether there is a code on the front). One end of the recovery pipe 311 is adjacent to one side of the gasket conveyor belt 307, and the other end enters the gasket processing part shell 304. The anti-pad high-frequency blowing valve 312 (connected to a high-pressure air pump, the force of the gas ejected here is much greater than the adsorption force of the negative pressure adsorption mechanism) is located on the other side of the gasket conveyor belt 307 and is opposite to one end of the recovery pipe 311. When the anti-pad detection sensor 310 detects the presence of an anti-pad, the anti-pad high-frequency blowing valve 312 sprays air to spray the gasket back into the gasket processing part shell 304 through the recovery pipe 311.

[0074] Due to the design location requirements of the rotary line breaking and padding machine, the outlet of the padding section of the pad feeding device 3 and the padding conveyor belt 307 cannot be directly connected. Therefore, this embodiment adds a padding pneumatic conveying unit between the two as a transition. The thrust of the front and rear pads during the discharge of the pads is used, supplemented by the wind force formed by the oblique air flow, to achieve the orderly forward movement of the pads, so that the pads can enter the padding conveyor belt 307 in an orderly manner, meeting the design requirements of the rotary line breaking and padding machine. An extra transition stroke can also ensure the distance between the front and rear pads. Figures 18 to 21 As shown, the gasket pneumatic conveying unit includes a feeding and blowing part 313 (such as a blower), an air delivery box 314, a feeding plate 315 and a limiting rod 316. The side of the air delivery box 314 is provided with an air inlet for connecting to the feeding and blowing part 313, and the top surface of the air delivery box 314 is provided with an air outlet. The feeding plate 315 covers the top surface of the air delivery box 314, and the plate surface of the feeding plate 315 is provided with a plurality of semi-conical air guide channels 3151 and air guide channels 3151 along its length. The air guide channel 3151 corresponds one to one with the air supply outlet. The air guide channel 3151 is arranged on the bottom surface of the feeding plate 315. The wind enters from one end of the air guide channel 3151, and is blown out obliquely from the air supply outlet after passing through the air guide channel 3151; one end of the feeding plate 315 extends to the output port 306 of the pad arrangement tray shell, and the other end extends to the gasket conveyor belt 307; the limiting rod 316 is arranged above the feeding plate 315, and is used to limit the height of the gasket blown up by the wind.

[0075] The padding device 4 includes a base plate 8 , a pad feed dial unit 401 and a padding unit 402 .

[0076] like Figure 23 and Figure 24 As shown, the pad feed dial unit 401 includes a pad feed dial shaft 4011 installed on the base plate 8, a pad feed dial 4012 fixed on the pad feed dial shaft 4011, a gasket guide plate 4013 fixed to the base plate 8 through a bracket, and a gasket correction plate 4014 fixed to the base plate 8 through a bracket. The padding unit 402 includes a padding dividing turntable 4022, on which a gasket limiting slot plate 40221 is fixed, and a notch is provided on the gasket limiting slot plate 40221 that can just accommodate a gasket. A gasket receiving groove 40121 is provided on the circumference of the gasket feed dial 4012 for receiving the gaskets output from the gasket conveyor belt 307 unit. One end of the gasket guide plate 4013 extends to the circumference of the gasket feed dial 4012, and the other end extends to the notch side of the gasket limiting groove plate 40221, for guiding the gaskets in the gasket feed dial 4012 to the gasket equal-division turntable 4022. The gasket correction plate 4014 is used to push the gaskets entering the gasket equal-division turntable 4022 completely into the notch of the gasket limiting groove plate 40221.

[0077] like Figure 25 and 26As shown, the padded unit 402 includes a padded main rotating shaft 4021 mounted on the base plate 8. The padded equally divided rotating disc 4022, the padded guide disc 4023, the padded tray 4024, and the padded annular track 4025 are sequentially arranged on the padded main rotating shaft 4021 from top to bottom. The padded annular track 4025 is arranged around the padded main rotating shaft 4021 and fixed to the base plate 8, with an undulating configuration. The padded tray 4024 is fixedly connected to the padded guide disc 4023 via bolts, and the padded guide disc 4023 is fixed to the padded main rotating shaft 4021. The padded equally dividing turntable 4022 is also fixed on the padded main rotating shaft 4021 (in actual design, the padded tray 4024, the padded equally dividing turntable 4022, and the padded guide plate 4023 are fixed together by bolts, and then the padded guide plate 4023 is fixed on the padded main rotating shaft 4021). The padded equally dividing turntable 4022 is provided with a padded top rod 4026, a padded guide column 4027, a padded guide rod 4028 and a three-hole connecting plate 4029. The hole on one side of the three-hole connecting plate 4029 is slidably connected to the padded guide rod 4028 through a linear bearing, and the other two holes are fixedly connected to the padded top rod 4026 and the padded guide column 4027 respectively. The lower end of the padded guide rod 4028 is fixed to the top surface of the padded equally dividing turntable 4022, and the padded guide column 4027 passes through the padded equally dividing turntable 4022 from top to bottom. 22. A padded guide plate 4023 and a padded tray 4024 are provided at their bottom ends with track wheels 4030 that travel on a padded circular track 4025. The padded equally divided turntable 4022 is provided with a through-hole 40222 positioned just below the notch in the gasket-limiting slot plate 40221. The padded push rod 4026, the notch in the gasket-limiting slot plate 40221, the through-hole 40222 in the padded equally divided turntable 4022, and the bottle cap receiving slot 40233 on the padded guide plate 4023 correspond to each other, and the corresponding components are coaxially arranged. An air suction channel 40261 extends through the padded push rod 4026. The upper end of the air suction channel 40261 is connected to a suction device via a pipeline, and the lower end is used to absorb gaskets that enter the notch in the gasket-limiting slot plate 40221.

[0078] The processing flow of the padding unit 402 is as follows: when the gasket passes through the gasket guide plate 4013 and enters the vicinity of the notch of the gasket limiting slot plate 40221 of the padding equal-division turntable 4022, it is sucked by the upper padding push rod 4026. When the padding equal-division turntable 4022 rotates to a certain angle, the sucked gasket is completely pushed into the notch of the gasket limiting slot plate 40221 by the gasket correction plate 4014. The bottle cap with broken line knurling is passed through the padding introduction plate 605 on the padding transition plate 6 and enters the bottle cap receiving groove 40233 of the padding guide plate 4023. When the padding equal-division turntable 4022 rotates, the padding push rod 4026 also rotates around the padding main rotating shaft 4021, and the track wheel 4030 below it rotates on the padding annular track 4025. During movement, due to the undulating design of the padded circular track 4025, the padded push rod 4026 can be raised or lowered along the padded guide rod 4028. When the padded push rod 4026 is lowered, the padded push rod 4026 drives the adsorbed gasket to be pushed into the bottle cap in the bottle cap receiving groove 40233 below to complete the padding. The design of the padded tray 4024 is to provide support for the bottle cap to prevent the bottle cap from escaping from the bottle cap receiving groove after the padded push rod 4026 is pressed down; when the padded push rod 4026 is raised, the suction channel 40261 stops suctioning, the gasket is left in the bottle cap, and the padded push rod 4026 is reset to perform the next round of operation; the bottle cap after padding passes through the detection introduction plate 704 and enters the detection transition plate 7 from the padded guide plate 4023.

[0079] like Figure 27 As shown, the detection unit 5 includes a pre-order detection part and a post-order detection part.

[0080] The pre-process detection section includes a first detection sensor 501, a second detection sensor 502, and a first defect rejection unit, which are arranged in sequence along the rotation direction of the detection transition plate 7. The first detection sensor 501 is used to detect the presence of a gasket in the bottle cap, and the second detection sensor 502 is used to detect defects on the top surface and interior of the bottle cap. If either the first detection sensor 501 or the second detection sensor 502 detects a defect, the bottle cap is judged to be defective. The first defect rejection unit includes a position adjustment mechanism 503, a high-frequency air blow valve 504 for defective products mounted on the position adjustment mechanism 503, and a defective product discharge hopper 505. The adjustment mechanism is used to adjust the blowing angle of the high-frequency air blow valve 504 for defective products. The high-frequency air blow valve 504 for defective products is used to blow defective bottle caps from the detection transition plate 7 into the defective product discharge hopper 505.

[0081] The subsequent detection part includes a discharge conveyor belt 506, a third detection sensor 507 arranged above the discharge conveyor belt 506, a second defective product discharge hopper 508 arranged on one side of the discharge conveyor belt 506, and a second high-frequency blowing valve 509 for defective products arranged on the other side of the discharge conveyor belt 506. The other end of the detection lead-out plate 705 extends to one end of the discharge conveyor belt 506, and is used to introduce the bottle caps on the detection transition plate 7 into the discharge 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 blowing valve 509 for defective products is used to blow the defective bottle caps on the discharge conveyor belt 506 into the second defective product discharge hopper 508.

[0082] The bottle caps entering the detection transition plate 7 will be detected by the first detection sensor 501 and the second detection sensor 502. If they are defective, they will be blown into the defective product discharge hopper 1 505. The good products will enter the discharge conveyor belt 506 through the detection guide plate 705. After detection by the third detection sensor 507, if there are defective products, they will be blown into the defective product discharge hopper 2 508. The good products will be discharged normally and enter the boxing process.

[0083] like Figure 28 As shown, the position adjustment mechanism 503 includes an angle adjustment block 5031, a linear adjustment rod 1 5032, a double-ended fixture 5034, and a linear adjustment rod 2 5033. The angle adjustment block 5031 has a mounting hole threaded with a tightening screw that screws into the mounting hole. One end of the linear adjustment rod 1 5032 is fixedly connected to the angle adjustment block 5031, and one end of the linear adjustment rod 2 5033 is fixedly connected to the defective high-frequency air blowing valve 1 504. The clamping portions at both ends of the double-ended fixture 5034 clamp and fix to the other ends of the linear adjustment rod 1 5032 and the other ends of the linear adjustment rod 2 5033, respectively. The linear adjustment rod 1 5032 and the linear adjustment rod 2 5033 are mutually perpendicular. The position adjustment mechanism 503 allows the jet angle of the defective high-frequency air blowing valve 1 504 and the jet distance from the bottle cap to be adjusted to accommodate the inspection of bottle caps of different sizes.

[0084] Preferably, the equipment of this embodiment may also be provided with lamps (not shown in the figure), which may be mounted on the equipment rack via lamp rails to facilitate workers in operating or repairing the equipment.

[0085] The power of the various rotating shafts in this embodiment can be achieved by arranging a motor under the bottom plate 8 and realizing power transmission and input through gear transmission.

[0086] The above embodiments are only used to illustrate the concept of the present invention, and are not intended to limit the protection of the present invention. Any non-substantial changes to the present invention using this concept should fall within the scope of protection of the present invention.
