Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of capping processing feeding equipment, specifically an automatic feeding device for capping processing. Background Technology
[0002] A gland is a critical functional component widely used in the housing construction of various industrial equipment, fluid transmission systems, mechanical seal assemblies, and devices. Its core physical form typically exhibits a specific geometric profile, and its structural design usually includes a physical interface for connection and positioning, as well as structural feature areas necessary to achieve its core functions. The essential function of this component is to act as a crucial sealing cover, pressure support, media isolation, or precision mating interface at specific physical interface locations. Through the effective intervention and precise positioning of its structure, it establishes a reliable, tight, and durable physical barrier and mating interface at connection points where it is necessary to isolate the internal and external environments, prevent fluid leakage, separate pressure zones, protect internal components from external interference, or ensure stable guiding support for critical rotating / sliding components.
[0003] Before entering any processing station, the original stacked or scattered state of the caps must undergo a controlled physical transfer process. The core purpose of this process is to redefine the spatial displacement and posture of individual or group caps according to the precise spatial requirements of subsequent processing steps. That is, to ensure that each cap blank or semi-finished product to be processed can continuously, stably and efficiently arrive at and be positioned at the designated starting point of the subsequent processing operation according to the preset sequence, precise position coordinates and required spatial orientation, so as to meet the requirements of continuous and uninterrupted production cycle of the caps in the processing flow.
[0004] In existing technology, a large number of caps fall onto the feeding mechanism together. During this process, the caps collide with each other, which can easily damage the surface of the caps. At the same time, the traditional feeding process requires manual straightening of the messy caps, which greatly reduces work efficiency and increases time costs. Therefore, an automatic feeding device for cap processing has been invented to address this defect. Utility Model Content
[0005] To address the issues of collisions that occur when a large number of caps fall together and the need for manual sorting of the disordered caps, this invention provides an automatic feeding device for cap processing.
[0006] This utility model is achieved through the following technical solution: An automatic feeding device for capping processing includes a support frame, a pushing mechanism, a dropping mechanism, and a feeding mechanism. The dropping mechanism includes a dropping cylinder mounted on the support frame. The pushing mechanism includes a connecting groove plate mounted on the support frame and a first motor mounted above the dropping cylinder. The connecting groove plate is used to receive the processed caps. A push plate is slidably connected to the connecting groove plate. A transmission component is connected to the output end of the first motor. The transmission component can drive the push plate to slide along the connecting groove plate and push the cap into the dropping cylinder. A lower cylinder is connected below the dropping cylinder. The inner diameter of the lower cylinder is 1.1 to 1.3 times the diameter of the cap.
[0007] The feeding mechanism includes a screw frame located below the feeding cylinder. Inside the screw frame is a rotating disk that can receive the caps falling from the lower cylinder. Below the rotating disk is a vibrator that can vibrate in the front-back and up-down directions. The vibrator can throw the caps on the rotating disk onto the screw frame. A discharge plate is installed at the outlet of the screw frame. A positioning component is installed on the screw frame that can organize the scattered caps on the screw frame into an orderly state and send them into the discharge plate.
[0008] After processing, the caps are conveyed onto the connecting trough plate. Then, the first motor pushes the caps into the feeding cylinder via a transmission assembly. The lower cylinder then allows the processed caps to fall one by one into the rotating disc, preventing collisions that can occur when a large number of caps fall together. Subsequently, the caps are thrown up by the up-and-down vibration of the vibrator. The back-and-forth vibration of the vibrator throws the caps onto the spiral frame. With the vibrator's up-and-down and back-and-forth vibrations, the caps move along the spiral frame. After passing the positioning assembly, the scattered caps on the spiral frame are organized into an orderly state and sent to the discharge plate, thus achieving orderly arrangement of the caps and saving manpower.
[0009] A further improvement of this utility model is that the outer surface of the rotating disk is a frustum shape that is narrower at the top and wider at the bottom, and the distance between the lower end face of the lower cylinder and the upper end face of the rotating disk is 1.1 to 1.3 times the height of the cap.
[0010] A further improvement of this utility model is that the transmission assembly includes a transmission disc fixedly installed at the output end of the first motor, a connecting rod rotatably connected to the lower part of the transmission disc, and the end of the connecting rod away from the transmission disc rotatably connected to the push plate. A striking device is installed at each end of the push plate, and the push plate can drive the striking device to strike the material discharge cylinder.
[0011] A further improvement of this utility model is that the outer surface of the material discharge cylinder is provided with a notch, one end of the connecting groove plate fits into the notch of the material discharge cylinder, and a base is installed at the bottom of the material discharge cylinder. The inner surface of the base is a frustum-shaped cone with high sides and low center. A through hole is provided at the lowest point of the inner surface of the base and it is connected to the inner wall of the lower cylinder.
[0012] A further improvement of this utility model is that the pressure cap is a coaxial body with one end thicker than the other, and a spiral upward track is provided on the spiral frame. The width of the track is equal to the diameter of the outer surface of the thickest part of the pressure cap. The spiral angle of the track is 90°~135°. A third positioning plate, a second positioning plate, and a first positioning plate are fixedly installed sequentially along the upward direction on the inner wall of the track away from the rotating disk. The first positioning plate and the second positioning plate are the same in shape and size. The first positioning plate is connected to the discharge plate, and the inner wall of the inlet part of the discharge plate is connected to the inner wall of the outlet part of the track.
[0013] A further improvement of this utility model is that a material holding bucket is fixedly installed inside the spiral frame, and a rotating disk is rotatably installed inside the material holding bucket. The outer surface of the material holding bucket is a truncated cylinder, the lowest point of the upper surface of the material holding bucket coincides with the inner wall of the track, and the height difference between the highest point of the upper surface of the material holding bucket and the inner wall of the track is greater than the height of the pressure cap.
[0014] A further improvement of this utility model is that the height difference between the upper surface of the material container and the track at the connection between the third positioning plate and the second positioning plate and the screw frame is less than the height of the pressure cap, and the height difference between the upper surface of the material container and the track at the connection between the first positioning plate and the screw frame is greater than the height of the pressure cap.
[0015] A further improvement of this utility model is that the cross-section of the second positioning plate is an arc shape that is concave towards the rotating disk, the central angle corresponding to the arc shape of the second positioning plate is 60°~100°, the outer surface of the second positioning plate is provided with an inclined surface, and the distance between the inclined surface of the second positioning plate and the center of the rotating disk gradually increases along the downward direction of the track.
[0016] A further improvement of this utility model is that the lower end face of the third positioning plate is parallel to the bottom surface of the inner wall of the track, and the distance between the lower end face of the third positioning plate and the bottom surface of the inner wall of the track is 1.1 to 1.2 times the height of the cover.
[0017] As can be seen from the above technical solution, the beneficial effects of this utility model are as follows: After processing, the caps are intermittently and periodically dropped onto the connecting groove plate by the conveying device. Then, the first motor pushes the caps into the feeding cylinder through the transmission component, and the lower cylinder ensures that the processed caps fall one by one into the rotating disk, thus avoiding collisions that occur when a large number of caps fall together. Subsequently, the caps are thrown up when the vibrator vibrates up and down. When the vibrator vibrates back and forth, the caps are thrown onto the spiral frame. Then, with the up and down and back and forth vibration of the vibrator, the caps move along the spiral frame. When the caps pass the positioning component, the positioning component organizes the scattered caps on the spiral frame into an orderly state and sends the caps into the discharge plate, thus achieving orderly arrangement of the caps and saving manpower.

Detailed Implementation
[0029] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0030] Example
[0031] As attached Figure 1 ~Appendix Figure 4 As shown, an automatic feeding device for capping processing includes a support frame 1, a pushing mechanism 2, a dropping mechanism 3, and a feeding mechanism 4. The dropping mechanism 3 includes a dropping cylinder 301 mounted on the support frame 1. The pushing mechanism 2 includes a support plate 201 fixedly mounted on the support frame 1. A connecting groove plate 202 is connected to the upper side of the support plate 201 by a fastening bolt. Multiple mounting seats 204 are fixedly mounted on the upper side of the dropping cylinder 301. Mounting plates 205 are welded to the mounting seats 204. A motor mount is fixedly mounted on the mounting plate 205. A first motor 206 is connected to the motor mount by a fastening bolt. The output end of the first motor 206 is connected to the mounting plate 205. The rotating connection and the formed pressure cap 6 are intermittently and periodically conveyed to the connecting groove plate 202 by the conveyor belt. The pressure cap 6 is a coaxial body with one end thicker than the other. The cross-section of the connecting groove plate 202 is U-shaped. A push plate 208 is slidably connected to the inner wall of the connecting groove plate 202. The output end of the first motor 206 is connected to a transmission component. The transmission component can drive the push plate 208 to slide along the connecting groove plate 202 and push the pressure cap 6 into the discharge cylinder 301. A lower cylinder 303 is connected below the discharge cylinder 301. The lower cylinder 303 is coaxial with the discharge cylinder 301. The inner diameter of the lower cylinder 303 is 1.1 to 1.3 times the diameter of the thickest part of the pressure cap 6.
[0032] As attached Figure 6 and attached Figure 7 As shown, the feeding mechanism 4 includes a screw frame 401 located below the dropping cylinder 301. Inside the screw frame 401 is a holding bucket 403 capable of receiving the caps 6 falling from the lower cylinder 303. A rotating disk 408 is rotatably installed inside the holding bucket 403. Below the rotating disk 408 is a vibrator capable of vibrating in the front-back and up-down directions. The vibrator can throw the caps 6 on the rotating disk 408 onto the screw frame 401. A discharge plate 402 is installed at the outlet of the screw frame 401. Two limiting plates 404 are symmetrically welded on the side of the discharge plate 402 facing the rotating disk 408. The cross-section of the combination of the limiting plate 404 and the discharge plate 402 is U-shaped. A positioning component is installed on the screw frame 401. The positioning component can organize the scattered caps 6 on the screw frame 401 into an orderly state and send them into the discharge plate 402.
[0033] After processing, the caps 6 are conveyed onto the connecting trough plate 202. Then, the first motor 206 pushes the caps 6 into the feeding cylinder 301 through the transmission assembly. The lower cylinder 303 then allows the processed caps 6 to fall one by one into the rotating disk 408, thus avoiding collisions that may occur when a large number of caps 6 fall together. Subsequently, the caps 6 are thrown up when the vibrator vibrates up and down. When the vibrator vibrates back and forth, the caps 6 are thrown onto the spiral frame 401. Then, with the up and down and back and forth vibration of the vibrator, the caps 6 move along the spiral frame 401. When the caps 6 pass the positioning assembly, the positioning assembly organizes the scattered caps 6 on the spiral frame 401 into an orderly state and sends the caps 6 into the discharge plate 402, thus achieving an orderly arrangement of the caps 6 and saving manpower.
[0034] As attached Figure 2 ~Appendix Figure 4 As shown, the transmission assembly includes a transmission disc 214 fixedly installed at the output end of the first motor 206. A connecting rod 207 is rotatably connected to the lower part of the transmission disc 214, and the end of the connecting rod 207 away from the transmission disc 214 is rotatably connected to the push plate 208. A sliding groove 210 is provided on the side of the mounting base 204. A movable block 211 is fixedly installed at each end of the push plate 208. Each movable block 211 is slidably installed on the inner wall of a sliding groove 210. A circular through hole is provided on the side of the movable block 211. An impact shaft 212 is slidably installed on the inner wall of the circular through hole of the movable block 211. The end of the impact shaft 212 facing the discharge cylinder 301 is hemispherical. A shock-absorbing sleeve is fitted on the outer surface of the hemispherical impact shaft 212. A spring 213 is wound on the outer surface of the impact shaft 212, and one end of the spring 213 is fixedly installed on the outer surface of the impact shaft 212. The other end of the impact shaft 212 is fixedly installed on the side of the moving block 211 away from the material drop cylinder 301. The first motor 206 drives the push plate 208 to slide along the inner wall of the connecting groove plate 202 through the connecting rod 207. The outer surface of the material drop cylinder 301 is provided with a notch. One end of the connecting groove plate 202 fits into the notch of the material drop cylinder 301. The lower part of the material drop cylinder 301 is equipped with a chassis 302. The inner surface of the chassis 302 is a frustum shape with high sides and low center. The lowest point of the inner surface of the chassis 302 is provided with a through hole and is connected to the inner wall of the lower cylinder 303. Then the pressure cover 6 is pushed into the chassis 302, and the impact shaft 212 strikes the material drop cylinder 301. The vibration generated by the strike disturbs the pressure cover 6 in the chassis 302, thereby preventing the pressure cover 6 from blocking the entrance of the lower cylinder 303 and being unable to fall into the second positioning plate 406.
[0035] The finished caps 6, processed in the previous step, are intermittently and periodically conveyed to the connecting trough plate 202 via a conveyor belt. Then, the first motor 206 starts, driving the connecting rod 207 via the transmission disc 214. The connecting rod 207 drives the push plate 208 to slide along the inner wall of the connecting trough plate 202, pushing the caps 6 on the connecting trough plate 202 into the discharge cylinder 301. They then fall into the lower cylinder 303 via the base plate 302. Simultaneously, the movement of the push plate 208 drives the impact shaft 212 to strike the discharge cylinder 301. The vibration generated by this strike disturbs the caps 6 in the base plate 302, preventing them from blocking the lower cylinder 303. The caps 6 then fall one by one onto the rotating disc 408 via the lower cylinder 303.
[0036] As attached Figure 6 ~Appendix Figure 9 As shown, the outer surface of the rotating disk 408 is a frustum shape, narrower at the top and wider at the bottom. The distance between the lower end face of the lower cylinder 303 and the upper end face of the rotating disk 408 is 1.1 to 1.2 times the height of the pressure cap 6, thus ensuring that the pressure caps 6 fall onto the rotating disk 408 one by one, avoiding multiple pressure caps 6 falling at once. A support disk 409 is rotatably connected to the lower part of the rotating disk 408. The support disk 409 is coaxial with the rotating disk 408. The material container 403 is also fixedly installed on the support disk 409 and is coaxial. A protective cover 504 is fixedly installed on the lower side of the support disk 409. A second motor 505 is fixedly installed on the protective cover 504. The output end of the second motor 505 is rotatably connected to the support plate 409 and the material container 403. The output end of the second motor 505 is fixedly connected to the rotating plate 408. The second motor 505 can drive the rotating plate 408 to rotate. A cover 502 is fixedly installed on the lower side of the protective cover 504. The vibrator is fixedly installed inside the cover 502 and connected to the protective cover 504. The centrifugal force of the rotating plate 408 and the vibration of the vibrator are combined to increase the force of throwing up the pressure cover 6.
[0037] The second motor 505 and the vibrator are started. The second motor 505 drives the rotating disk 408 to rotate. The up and down rotation of the vibrator throws the pressure cover 6 on the rotating disk 408 up. The back and forth vibration of the vibrator and the centripetal force generated when the rotating disk 408 rotates simultaneously throw the pressure cover 6 onto the screw frame 401.
[0038] As attached Figure 6 ~Appendix Figure 8As shown, the spiral frame 401 is equipped with a spirally upward track. The width of the track is equal to the diameter of the outer surface of the thickest part of the pressure cap 6. The spiral angle of the track is 90°~135°. A material container 403 is fixedly installed inside the spiral frame 401. A rotating disk 408 is rotatably installed inside the material container 403. The outer surface of the material container 403 is a truncated cylinder. The lowest point of the upper surface of the material container 403 coincides with the inner wall of the track. The height difference between the highest point of the upper surface of the material container 403 and the inner wall of the track is greater than the height of the pressure cap 6. A third positioning plate 407, a second positioning plate 406, and a first positioning plate 405 are sequentially fixedly installed along the upward direction on the inner wall of the track away from the rotating disk 408. The pressure cap 6 is moved along the track by the vibration of the vibrator. The track moves upward, allowing the cap 6 to sequentially contact the third positioning plate 407, the second positioning plate 406, and the first positioning plate 405. The first positioning plate 405 and the second positioning plate 406 are identical in shape and size. The first positioning plate 405 is connected to the discharge plate 402, and the inner wall of the inlet portion of the discharge plate 402 is connected to the inner wall of the outlet portion of the track. The width of the inner wall of the discharge plate 402 is equal to the diameter of the outer surface of the thickest part of the cap 6, and the height of the limiting plate 404 is equal to the height of the thickest part of the cap 6. By having the cap 6 sequentially contact the third positioning plate 407, the second positioning plate 406, and the first positioning plate 405, the disordered cap 6 is straightened into an orderly state and sent into the discharge plate 402, thus facilitating subsequent processes.
[0039] As attached Figure 6 and attached Figure 7 As shown, at the connection between the third positioning plate 407 and the second positioning plate 406 and the screw frame 401, the height difference between the upper surface of the material container 403 and the track is less than the height of the pressure cap 6; at the connection between the first positioning plate 405 and the screw frame 401, the height difference between the upper surface of the material container 403 and the track is greater than the height of the pressure cap 6; the cross-section of the second positioning plate 406 is an arc shape concave towards the rotating disk 408, and the central angle corresponding to the arc shape of the second positioning plate 406 is 60°~100°; the outer surface of the second positioning plate 406 is provided with a slope; the second positioning plate 405... The distance between the inclined plane and the center of the rotating disk 408 gradually increases along the downward direction of the track; the lower end face of the third positioning plate 407 is parallel to the bottom surface of the inner wall of the track, and the distance between the lower end face of the third positioning plate 407 and the bottom surface of the inner wall of the track is 1.1 to 1.2 times the height of the cover 6. The messy cover 6 is straightened by the third positioning plate 407, the second positioning plate 406, and the first positioning plate 405. The cover 6 that cannot be straightened falls back onto the rotating disk 408. The straightened cover 6 is sent into the discharge plate 402 through the first positioning plate 405.
[0040] The caps 6 that fall onto the auger 401 come in various shapes, some vertical, some tilted, and some horizontal. When the vibrator vibrates up and down, the caps 6 are thrown up again. When the vibrator vibrates backward, the surface of the auger 401 sways backward a short distance. At this time, the caps 6 do not move in the forward and backward direction due to inertia. When the caps 6 fall back onto the surface of the auger 401 under the action of gravity, the caps 6 move forward a short distance. The above process is repeated continuously, so that the caps 6 continuously move along the track surface of the auger 401 under the action of the vibrator. At this time, some of the caps 6 that are tilted and horizontal become vertical during the process of being thrown up and falling. Then, under the limiting action of the third positioning plate 407, they continue to move along the track of the auger 401. The remaining caps 6 that are tilted and horizontal fall back into the rotating disk 408 and are then thrown back onto the auger 401.
[0041] The vertically positioned cap 6 has two forms: one with the larger diameter end facing upwards, and the other with the smaller diameter end facing upwards. When the larger diameter end faces upwards and passes the second positioning plate 406, the upper outer surface of the cap 6 contacts the inclined surface of the second positioning plate 406. Under the action of the inclined surface of the second positioning plate 406, the cap 6 gradually flips over and falls onto the rotating disk 408. The above process is repeated. When the smaller diameter end faces upwards and passes the second positioning plate 406, the second positioning plate 406 gradually passes through the second positioning plate 406 and moves towards the third positioning plate 407. Then, the cap 6 enters the discharge plate 402 through the third positioning plate 407 and enters the next processing step through the discharge plate 402.
[0042] The working principle of this embodiment is as follows.
[0043] (i) The cap 6, processed in the previous step, is intermittently and periodically delivered to the connecting trough plate 202 via a conveyor belt. Then, the first motor 206 starts, and the first motor 206 drives the connecting rod 207 to move via the transmission disc 214. The connecting rod 207 drives the push plate 208 to slide along the inner wall of the connecting trough plate 202, thereby pushing the cap 6 on the connecting trough plate 202 into the dropping cylinder 301, and then falling into the lower cylinder 303 via the chassis 302. At the same time, the movement of the push plate 208 drives the impact shaft 212 to strike the dropping cylinder 301. The vibration generated by the tapping disturbs the pressure cap 6 in the chassis 302, thereby preventing the pressure cap 6 from blocking the lower cylinder 303. The pressure cap 6 falls one by one onto the rotating disk 408 through the lower cylinder 303. At the same time, the second motor 505 and the vibrator are started. The second motor 505 drives the rotating disk 408 to rotate. The up and down rotation of the vibrator throws the pressure cap 6 on the rotating disk 408 up. The back and forth vibration of the vibrator and the centripetal force generated by the rotation of the rotating disk 408 work together to throw the pressure cap 6 onto the screw frame 401.
[0044] (ii) The caps 6 that fall onto the screw frame 401 are in various shapes, some vertical, some inclined, and some horizontal. When the vibrator vibrates up and down, the caps 6 are thrown up again. When the vibrator vibrates backward, the surface of the screw frame 401 sways backward a short distance. At this time, the caps 6 do not move in the forward and backward direction under the action of inertia. When the caps 6 fall onto the surface of the screw frame 401 under the action of gravity, the caps 6 advance a short distance. Then, the above process is repeated continuously, so that the caps 6 continuously advance along the track surface of the screw frame 401 under the action of the vibrator. At this time, some of the caps 6 that are inclined and horizontal become vertical in the process of being thrown up and falling. Then, under the limiting action of the third positioning plate 407, they continue to advance along the track of the screw frame 401. The remaining caps 6 that are inclined and horizontal fall back into the rotating disk 408 and are then thrown back onto the screw frame 401.
[0045] (III) The cap 6 in the vertical position has two forms: one with the larger diameter end facing upwards and the other with the smaller diameter end facing upwards. When the larger diameter end faces upwards and passes the second positioning plate 406, the upper outer surface of the cap 6 contacts the inclined surface of the second positioning plate 406. Under the action of the inclined surface of the second positioning plate 406, the cap 6 gradually flips over and falls onto the rotating disk 408. Then the above process is repeated. When the smaller diameter end faces upwards and passes the second positioning plate 406, the second positioning plate 406 gradually passes through the second positioning plate 406 and moves towards the third positioning plate 407. Then the cap 6 enters the discharge plate 402 through the third positioning plate 407 and enters the next processing step through the discharge plate 402.
