[0007] As a preferred embodiment of the present invention: the detection component includes a fixed column, a lifting circular plate is slidably connected to the inner wall of the fixed column, a connecting column is fixedly installed at the bottom of the lifting circular plate, a reset spring is provided on the inner wall of the fixed column, a detection plate is fixedly installed at the bottom of the connecting column, an infrared detection head is fixedly installed at the bottom of the detection plate, and a pressure sensor is fixedly installed on the inner wall of the fixed column.

[0008] As a preferred technical solution of the present invention: the flaring assembly includes a fixed cylinder, a limiting rod is fixedly installed on the inner wall of the fixed cylinder, a sliding circular plate is slidably connected to the inner wall of the limiting rod, a movable column is fixedly installed at the bottom of the sliding circular plate, and a reset spring is provided on the inner wall of the fixed cylinder.

[0009] As a preferred technical solution of the present invention: the number of the limiting rods is two, and the two limiting rods are symmetrically arranged on the inner wall of the fixed cylinder, and the two limiting rods penetrate through both sides of the sliding circular plate.

[0010] As a preferred embodiment of the present invention, the number of detection components is two, and the two detection components are respectively disposed at the bottom of the sliding plate, and the two detection components are electrically connected to the control center.

[0011] As a preferred embodiment of the present invention: the shape of the sealing plate fits the bottom of the third transmission channel, and the inner wall shape of the limiting slider fits the outer wall of the third transmission channel.

[0012] As a preferred embodiment of the present invention, the number of workstation slots is ten, and the ten workstation slots are arranged in a circular array above the rotating disk.

[0013] As a preferred embodiment of the present invention, the worm is located outside the worm wheel, and the worm meshes with the worm wheel.

[0014] As a preferred embodiment of the present invention: the diameter of the feeding trough is adapted to the inner wall diameter of the work station trough, and the positions of the feeding trough and the work station trough are corresponding; the extrusion column is located above the feeding trough, and the diameter of the extrusion column is adapted to the inner wall diameter of the feeding trough.

[0015] The present invention has the following beneficial effects: 1. The multi-station rotary necking machine structure uses the combined transmission of the corrugated plate feeding device and the first transmission channel to move the material towards the extension end of the feeding cylinder. The detection device and the pushing cylinder work together to push unqualified materials back into the hopper. The feeding cylinder then pushes the material above the posture adjustment device, which adjusts the material's posture. The feeding cylinder then pushes the material above the second transmission channel, which in turn pushes it into the third transmission channel. The drive motor, transmission column, and transmission belt work together to transmit the material above the sealing plate. The activation of the reset cylinder pulls the sealing plate, opening the bottom of the third transmission channel and allowing the material to fall into the workstation slot at the bottom of the third transmission channel.

[0016] 2. The multi-station rotary necking machine structure, through the activation of a high-thrust composite cylinder, causes the flaring assembly, lower pressure column one, lower pressure column two, extrusion column, and two detection components to move downwards. The detection components, located outside the flaring assembly, use a detection plate, connecting column, return spring one, and pressure sensor inside to detect the presence of a sheet metal cylinder inside the lower station slot. The downward movement of the flaring assembly causes the inclined surface outside the flaring assembly to flare the sheet metal cylinder. The downward movement of the detection components outside lower pressure column one allows the infrared detection head at the bottom to detect the presence of filler material inside the sheet metal cylinder. The downward movement of the extrusion column causes the necking slot to move downwards, thus performing the necking process on the sheet metal cylinder. The downward movement of lower pressure column two causes the receiving slot to collect the top of the sheet metal cylinder, thus compressing and sealing it. The downward movement of the extrusion column causes the extrusion column to push the material inside the station slot downwards through the feeding slot, thereby completing the sealing of the sheet metal cylinder and filler material.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-11 A multi-station rotary necking machine structure includes a support frame 1. A high-thrust composite cylinder 2 is fixedly installed on the top of the support frame 1. A sliding plate 3 is fixedly installed on the telescopic end of the high-thrust composite cylinder 2. A feeding assembly 4 is provided on the outer wall of the support frame 1. A rotating disk 5 is rotatably connected to the inner wall of the support frame 1. A protective shell 6 is fixedly installed on the bottom of the support frame 1. A rotating motor 7 is fixedly installed on the outer wall of the protective shell 6. A worm gear 8 is fixedly installed on the bottom of the rotating disk 5. A material discharge groove 9 is opened on the inner wall of the support frame 1. A station groove 19 is opened at the top of the rotating disk 5. A sliding plate 10 is fixedly installed on the bottom of the support frame 1. A worm gear 11 is fixedly installed on the output shaft of the rotating motor 7. A detection assembly 12 and a flaring assembly 13 are respectively provided on the bottom of the sliding plate 3. A first pressing column 14, a second pressing column 15 and an extrusion column 16 are respectively fixedly installed on the bottom of the sliding plate 3. A necking groove 17 is opened on the bottom of the extrusion column 16. A receiving groove 18 is opened on the bottom of the second pressing column 15.

[0021] In the above structure, the sliding plate 10 is located below the feeding trough 9, so that after the sealed iron tube passes through the feeding trough 9, the iron tube falls above the sliding plate 10 and is transported downward by the sliding plate 10. At this time, by placing the collection frame below the sliding plate 10, the iron tube above the sliding plate 10 moves into the collection frame by gravity.

[0022] In a preferred embodiment: the feeding assembly 4 includes a hopper 401, a corrugated board feeding device 402 fixedly mounted on the inner wall of the hopper 401, a first transmission channel 403 fixedly mounted on the outer wall of the hopper 401, a pushing cylinder 404 and a drive motor 405 fixedly mounted on the outer wall of the first transmission channel 403, a detection device 406 fixedly mounted on the top of the first transmission channel 403, an attitude adjustment device 407 fixedly mounted on the outer wall of the first transmission channel 403, a second transmission channel 410 fixedly mounted on the outer wall of the attitude adjustment device 407, and a third transmission channel 411 fixedly mounted on the outer wall of the second transmission channel 410. A feeding cylinder 409 is fixedly installed on the outer wall of the first transmission channel 403. A detection device 418 is fixedly installed on the top of the feeding cylinder 409. A control center 408 is provided at the bottom of the feeding cylinder 409. A sealing plate 412 is slidably connected to the bottom of the third transmission channel 411. A drive motor 413 is fixedly installed on the top of the third transmission channel 411. A transmission column 414 is fixedly installed on the output shaft of the drive motor 413. A transmission belt 415 is rotatably sleeved on the outer wall of the transmission column 414. A limit slider 416 is fixedly installed on the outer wall of the sealing plate 412. A reset cylinder 417 is fixedly installed on the bottom outer wall of the third transmission channel 411.

[0023] In the above structure, the detection device 2 418 and the detection device 1 406 are electrically connected to the control center 408. When the detection device 1 406 detects an error in the posture of the bottom sheet metal cylinder, it sends an electrical signal to the control center 408. This causes the control center 408 to activate the pusher cylinder 404, which pushes the sheet metal cylinder into the hopper 401. Simultaneously, when the sheet metal cylinder reaches below the detection device 2 418, the detection device... The second cylinder 418 sends an electrical signal to the control center 408, causing the control center 408 to operate the feeding cylinder 409 to push the sheet metal cylinder above the attitude adjustment device 407. The attitude adjustment device 407 adjusts the attitude of the sheet metal cylinder. After the attitude adjustment is completed, the feeding cylinder 409 continues to push the sheet metal cylinder into the second transmission channel 410. At the same time, through the symmetrical arrangement of the two high-thrust compound cylinders 2, the two high-thrust compound cylinders 2 respectively perform the feeding work of the sheet metal cylinder and the filler.

[0024] In a preferred embodiment: the detection component 12 includes a fixed column 1201, a lifting circular plate 1202 slidably connected to the inner wall of the fixed column 1201, a connecting column 1203 fixedly installed at the bottom of the lifting circular plate 1202, a return spring 1204 provided on the inner wall of the fixed column 1201, a detection plate 1205 fixedly installed at the bottom of the connecting column 1203, an infrared detection head 1206 fixedly installed at the bottom of the detection plate 1205, and a pressure sensor 1207 fixedly installed on the inner wall of the fixed column 1201.

[0025] In the above structure, by matching the diameter of the bottom of the detection plate 1205 with the diameter of the inner wall of the feeding trough 9, the bottom of the detection plate 1205 fits against the top of the iron tube after the detection assembly 12 moves downward, causing the detection plate 1205 to move upward. This causes the detection plate 1205 to drive the connecting column 1203 and the lifting circular plate 1202 to move upward, so that the lifting circular plate 1202 activates the pressure sensor 1207, thereby indicating that there is an iron tube inside the feeding trough 9.

[0026] In a preferred embodiment: the flaring assembly 13 includes a fixed cylinder 1301, a limiting rod 1302 is fixedly installed on the inner wall of the fixed cylinder 1301, a sliding circular plate 1303 is slidably connected to the inner wall of the limiting rod 1302, a movable column 1304 is fixedly installed at the bottom of the sliding circular plate 1303, and a second return spring 1305 is provided on the inner wall of the fixed cylinder 1301.

[0027] In the above structure, the inclined surface at the bottom of the fixed cylinder 1301 is designed so that after the fixed cylinder 1301 enters the sheet metal tube, the inclined surface at the bottom of the fixed cylinder 1301 is widened to the top of the sheet metal tube, which facilitates the subsequent placement of filling material inside.

[0028] In a preferred embodiment, there are two limiting rods 1302, and the two limiting rods 1302 are symmetrically arranged on the inner wall of the fixed cylinder 1301, and the two limiting rods 1302 pass through both sides of the sliding circular plate 1303.

[0029] In the above structure, the sliding circular plate 1303 is penetrated by two limiting rods 1302, so that the sliding circular plate 1303 can only slide on the outer wall of the two limiting rods 1302 when it moves, thereby limiting the sliding circular plate 1303 and preventing it from tilting when it moves.

[0030] In a preferred embodiment, there are two detection components 12, and the two detection components 12 are respectively disposed at the bottom of the sliding plate 3. The two detection components 12 are electrically connected to the control center 408.

[0031] In the above structure, the sheet metal cylinder can be detected by two detection plates 1205, and the infrared laser emitted by the infrared detection head 1206 can detect the filling material inside the sheet metal cylinder. At the same time, the pressure sensor 1207 and the infrared detection head 1206 can send the detection results to the control center 408, and the control center 408 can remind the staff.

[0032] In a preferred embodiment, the shape of the sealing plate 412 fits the bottom of the third transmission channel 411, and the inner wall shape of the limiting slider 416 fits the outer wall of the third transmission channel 411.

[0033] In the above structure, the bottom opening of the third transmission channel 411 is sealed by the sealing plate 412, so that the iron tube on the inner wall of the third transmission channel 411 will not fall down through the lower opening. At the same time, the limiting slider 416 is attached to the outer wall of the third transmission channel 411, so that the limiting slider 416 and the sealing plate 412 are limited, so that the sealing plate 412 and the limiting slider 416 cannot be separated from the outer wall of the third transmission channel 411.

[0034] In a preferred embodiment, there are ten workstation slots 19, and the ten workstation slots 19 are arranged in a circular array above the rotating disk 5.

[0035] In the above structure, the ten workstation slots 19 allow a maximum of ten sheet metal tubes to exist above the equipment at the same time. The ten sheet metal tubes can change positions by the continuous rotation of the rotating disk 5, thereby changing the processing station where the sheet metal tubes are located.

[0036] In a preferred embodiment, the worm 11 is located outside the worm wheel 8, and the worm 11 meshes with the worm wheel 8.

[0037] In the above structure, by starting the rotating motor 7, the rotating motor 7 drives the worm 11 to rotate, which in turn drives the worm wheel 8 to rotate through meshing with the worm wheel 8. At the same time, the rotation of the worm wheel 8 drives the rotating disk 5 to rotate, which in turn drives the top work station groove 19 to rotate.

[0038] In a preferred embodiment: the diameter of the feeding trough 9 is adapted to the inner wall diameter of the station trough 19, and the positions of the feeding trough 9 and the station trough 19 correspond to each other. The extrusion column 16 is located above the feeding trough 9, and the diameter of the extrusion column 16 is adapted to the inner wall diameter of the feeding trough 9.

[0039] In the above structure, when the work station trough 19 drives the sheet metal cylinder to the top of the unloading trough 9, the high-thrust compound cylinder 2 drives the sliding plate 3 to move downward, which in turn drives the extrusion column 16 to move downward, thereby causing the extrusion column 16 to push the sheet metal cylinder inside the work station trough 19 downward, and thus causing the sheet metal cylinder inside the work station trough 19 to fall downward through the unloading trough 9.

[0040] Working Principle: When using the equipment, the sheet metal cylinder and filler are placed inside two hoppers 401. The conveying devices 402 inside the two hoppers 401 then transport the sheet metal cylinder and filler upwards through two first transmission channels 403. The first transmission channels 403 then transport the sheet metal cylinder and filler towards the feeding cylinder 409. Simultaneously, sheet metal cylinders and fillers with incorrect posture are detected by detection device 1 406 and pushed back into the hopper 401 by the pushing cylinder 404. After detection device 2 418 detects the material in front of the extension end of the feeding cylinder 409, the feeding cylinder 409 is activated, pushing the material upwards towards the posture adjustment device 407. The posture adjustment device 407 adjusts the material's posture. Simultaneously, the feeding cylinder 409 continues to move, conveying the material to the top of the second transmission channel 410. The material is then conveyed through the second transmission channel 410 to the interior of the third transmission channel 411. When the sheet metal cylinder is in contact with the top of the sealing plate 412, the reset cylinder 417 is activated, causing the sealing plate 412 to move. This causes the sheet metal cylinder inside the third transmission channel 411 to fall into the workstation slot 19 located below the third transmission channel 411 by gravity. At this time, the rotating motor 7 is activated, causing the worm gear 11 to rotate. The worm gear 11, through meshing with the worm wheel 8, drives the worm wheel 8 to rotate. Simultaneously, the rotation of the worm wheel 8 drives the rotating disk 5 to rotate, causing the rotating disk 5 to drive the top... The workstation slot 19 rotates, causing the workstation slot 19 to move the sheet metal cylinder to the bottom of the detection component 12 located outside the flaring assembly 13. The activation of the high-thrust compound cylinder 2 causes the sliding plate 3 to move downwards, which in turn causes the sliding plate 3 to move the flaring assembly 13, the first pressing column 14, the second pressing column 15, the extrusion column 16, and the two detection components 12 downwards. At this time, the downward movement of the detection component 12 located outside the flaring assembly 13 causes the detection plate 1205 located outside the flaring assembly 13 to come into contact with the sheet metal cylinder on the inner wall of the workstation slot 19. The detection plate 1205 is then pushed upwards, causing the detection plate 1205 to move upwards along with the connecting column 1203 and the lifting circular plate 1202, thus causing the lifting circular plate 1202 to move upwards. The bottom of the lifting plate 1202 is attached to the pressure sensor 1207, causing the pressure sensor 1207 to detect that the lifting plate 1202 has moved upward, indicating that there is a sheet metal tube inside the lower work station slot 19. The downward movement of the flaring assembly 13 causes the fixed cylinder 1301 to flare at the top of the sheet metal tube after entering it, facilitating the subsequent placement of filler material. Meanwhile, the rotating disk 5 continues to rotate. When the work station slot 19 rotates to the middle of the flaring assembly 13 and the detection assembly 12 near the outside of the lower pressure column 14, the filler material is placed into the sheet metal tube through the feeding assembly 4 on the other side. The downward movement of the extrusion column 16 causes the narrowing groove 17 to move downward, narrowing the top of the sheet metal tube towards the center.The downward movement of the second pressing column 15 brings the top of the sheet metal cylinder inside the receiving trough 18, causing the second pressing column 15 to continue moving downward and sealing the top of the sheet metal cylinder. The downward movement of the extrusion column 16 pushes the finished product inside the workstation trough 19 downward, causing it to fall through the discharge trough 9 onto the sliding plate 10. The sliding plate 10 then transfers the material into the collecting frame.
