Description

Technical Field

[0001] The present invention belongs to the technical field of bar feeding, and specifically relates to an industrial hardware bar feeder. Background Art

[0002] An industrial hardware bar feeder refers to a feeding machine that coordinates with equipment capable of continuously and circularly processing bar-shaped materials to achieve automatic feeding, thereby improving the processing efficiency and automation level of the equipment. A bar is a straight product of metal plastic processing with a relatively large ratio of length to cross-sectional perimeter and no obvious convex or concave parts on the cross-section. Bars are widely used in industrial fields such as construction, machinery, automobiles, and ships. Currently, most industrial hardware bar feeders use a pressing bar to drive a central shaft clamp to push the bar to move in the feeding trough to complete the feeding. And to ensure the smooth completion of the feeding process, a cover plate is generally installed on the frame to prevent the bar from vibrating during movement; the existing cover plate and feeding support are generally made of metal materials. When they collide with each other, it is easy to generate relatively large vibrations and noises. Moreover, when the existing feeder conveys the bar, the debris and dust on the bar will gradually contaminate the feeder during the conveying process of the feeder, resulting in a poor environment during the conveying process. And the bar and the feeder also need to be cleaned one by one again after the conveying ends to remove the remaining stains, thus increasing the workload. Summary of the Invention

[0012] Preferably, the rotation and lifting structure consists of a cross bar, a disc, and a semi-circular pull plate movably sleeved on the disc. A U-shaped groove is formed at the bottom end of the semi-circular pull plate. The two ends of the cross bar are respectively fixedly connected to a second spur gear and the outer wall of one end of the disc. The lifting and limiting structure is composed of a lifting plate rod, a rotating shaft, and a cylinder slidably connected to the outer wall of the lifting plate rod.

The bottom end of the air box is fixedly connected to the top end of the support plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: When the bar stock of the present invention is passively conveyed by the feeder, the limiting plates installed on the inner walls of both ends of the feeder will limit the bar stock during transportation to prevent excessive deviation during the transportation of the bar stock, resulting in blockage and jamming. At the same time, when the bar stock is limited by the limiting plate, it will be briefly rotationally clamped in the material groove formed on the limiting plate. Since the limiting plate is made of PU material, it can also play a certain buffering effect while limiting the bar stock. When the limiting plate is squeezed by the bar stock, the limiting plate will be immediately squeezed against multiple springs, causing them to deform. Thus, the limiting plate jointly buffers the vibration generated during the feeding of the bar stock and the impact force on the feeding support, thereby avoiding the vibration and noise generated when the bar stock collides with the feeder. In the process of transporting the bar, the present invention first needs to start the first power source to drive the spur gear two fixedly connected thereto and the spur gear one meshed with the spur gear two to rotate. Thus, the rotating rod is driven to rotate by the spur gear one. Among them, the first power source is specifically a motor. The rotating rod will drive the rotating cylinder and the bristles installed on the outer wall of the rotating cylinder to rotate synchronously. Thus, the bristles can clean the surface of the bar temporarily clamped in the material groove. The frictional force during the cleaning process will drive the bar to rotate, and thus the outer wall of the bar can be comprehensively cleaned. At the same time, during the cleaning process of the bar, the generated debris and dust can synchronously start the suction pump installed on the U-shaped bracket. When the suction pump operates, it sucks the debris and dust through the slot plate on the suction pipe and the multiple suction cups installed at the bottom end of the slot plate, so as to maintain the cleanliness of the feeder and the bar and improve the working environment during the feeding process; When the rotating rod rotates in the present invention, it will also drive the support rod fixedly connected thereto and the cam on the support rod to rotate. Thus, it strikes the inner wall of the top end of the air box and the outer wall of the top end of the fuel tank, causing the air box to move upward through the corrugated pipe, driving the gas to enter from the top air funnel, and passing through the filter plate to sieve the gas, so as to avoid dust falling and adhering to the spur gear one 26 and the spur gear two 27. At the same time, the filtered clean gas will be discharged through the air funnels installed at the left and right ends of the air box. The one-way valves on the three air funnels are used to control the one-way output of the gas to ensure the fluidity of the gas inside the air box. Then, due to the rubber material at the top end of the fuel tank being struck, it will move slightly downward when struck, squeezing the sponge filled with lubricating oil inside, and thus the oil flows downward. Through the small oil holes opened, the oil can be slightly dropped onto the spur gear two, so as to avoid jamming and unsmooth rotation when the spur gear one and the spur gear two are meshed and rotated for a long time; When the motor drives the spur gear two to rotate in the present invention, it will also drive the cross bar installed at the other end of the spur gear two to rotate. The rotation of the cross bar will drive the disk to rotate in real time. Since the installation position of the cross bar on the disk is close to the edge position of the disk, when the disk rotates, it will drive the semi-circular pull plate to rotate in a short-distance circular motion without rotating around the axis. Thus, it drives the lifting plate rod rotatably connected to the rotating shaft to move up and down. The cylinder is used to limit the lifting plate rod, thereby driving the damping surface under the bar to lift up and down at a certain distance, cooperating with the vibration frequency, and at the same time jointly buffering the impact force and vibration on the bottom of the feeder by the limiting plate and the spring.

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] As Figures 1 to 10 shown, the present invention provides an industrial hardware bar feeding machine, including a feeding machine 1. Limiting and buffering structures are provided on the inner walls at both ends of the feeding machine 1. A damping cotton is adhesively connected to the feeding machine 1. It further includes: Cleaning unit 2, the cleaning unit 2 is located on the feeder 1. The cleaning unit 2 includes a U-shaped bracket 21 and bristles 22 disposed within the U-shaped bracket 21. A rotating structure is provided within the bristles 22. A lifting and positioning structure is provided on the outer wall of one end of the U-shaped bracket 21. A rotating engagement structure is further provided on the rotating structure. A rotating and lifting structure is provided on the rotating engagement structure. A lifting limit structure is provided on the rotating and lifting structure. A lubricating structure is provided on the other end of the rotating engagement structure. And a clamping and lifting structure is further provided on the rotating engagement structure. A material suction structure is provided on the top end of the U-shaped bracket 21. And an aggregate structure is further provided on the top end of the U-shaped bracket 21.

[0019] Adopting the above solution: The limiting plates 11 installed on the inner walls at both ends of the feeder 1 will limit the position of the bar during transportation, preventing excessive deviation of the bar during transportation. At the same time, the bar will be temporarily rotationally clamped in the material grooves 13 opened on the limiting plates 11. When the limiting plates 11 are squeezed by the bar, the limiting plates 11 will be immediately squeezed against multiple springs 12, causing them to deform. Thus, in combination with the limiting plates 11, the vibration generated during the bar feeding and the impact force on the feeding support are buffered, thereby avoiding the vibration and noise generated when the bar collides with the feeder 1. At the same time, during the bar transportation process, it is also necessary to first start the first power source to drive the fixedly connected second spur gear 27 and the first spur gear 26 meshed with the second spur gear 27 to rotate. Thus, the rotating rod 24 is driven to rotate by the first spur gear 26. The rotating rod 24 in rotation will drive the rotating cylinder 23 and the bristles 22 installed on the outer wall of the rotating cylinder 23 to rotate synchronously. Thus, the bristles 22 can clean the surface of the bar temporarily clamped in the material groove 13. At the same time, when the rotating rod 24 rotates, it will also drive the fixedly connected support rod 298 and the cam 299 on the support rod 298 to rotate. Thus, it strikes the inner wall of the top end of the air box 291 and the outer wall of the top end of the oil tank 296, causing the air box 291 to move upward through the corrugated pipe 292, driving the gas to enter from the top air hopper 294, and passing the gas through the filter mesh plate 293 to screen it, preventing dust from falling and adhering to the first spur gear 26 and the second spur gear 27. Then, due to the rubber material at the top of the oil tank 296 being struck, it will move slightly downward when struck, squeezing the sponge 297 filled with lubricating oil inside. Thus, the oil flows downward, and through the small oil holes opened, a small amount of the oil can drip onto the second spur gear 27, preventing jamming and unsmooth rotation when the first spur gear 26 and the second spur gear 27 mesh and rotate for a long time. The frictional force during the cleaning process will drive the bar to rotate. At the same time, during the bar cleaning process, the generated debris and dust can synchronously start the suction pump 232 installed on the U-shaped bracket 21. When the suction pump 232 operates, it sucks the debris and dust through the slot plate 235 on the suction pipe 234 and the multiple suction cups 236 installed at the bottom of the slot plate 235, maintaining the cleanliness of the feeder 1 and the bar, improving the working environment during the feeding process. The sucked debris and dust will pass through the delivery pipe 233 at one end of the suction pump 232, and the debris and dust will be introduced into the waste box 237.

[0020] The limiting and buffering structure is composed of the limiting plates 11, multiple springs 12, and multiple material grooves 13 opened at one end of the limiting plates 11. Both ends of each spring 12 are fixedly connected between the outer wall of the other end of the limiting plate 11 and the inner wall of the feeder 1.

[0021] Adopting the above solution: When the bar is passively conveyed by the feeder 1, the limiting plates 11 installed on the inner walls at both ends of the feeder 1 will limit the bar during transportation, preventing excessive deviation of the bar during transportation, resulting in blockage and jamming. At the same time, when the bar is limited by the limiting plate 11, the bar will be temporarily rotationally clamped in the material groove 13 opened on the limiting plate 11. Since the limiting plate 11 is made of PU material, when limiting the bar, it can also play a certain buffering effect synchronously. When the limiting plate 11 is squeezed by the bar, the limiting plate 11 will be squeezed against multiple springs 12 for the first time, causing them to deform. Thus, in combination with the limiting plate 11, it buffers the vibration generated during the feeding of the bar and the impact force on the feeding support, thereby avoiding the vibration and noise generated when the bar collides with the feeder 1.

[0022] The rotating structure is composed of a rotating cylinder 23 and a rotating rod 24 fixedly connected to the inner wall of the rotating cylinder 23. The outer wall of the rotating cylinder 23 is fixedly connected to one end of the brush hair 22. The rotating rod 24 is rotatably connected to the U-shaped support 21, and one end of the rotating rod 24 penetrates through the inner and outer walls of one end of the U-shaped support 21. A rectangular groove is also penetrated and opened on the inner and outer walls of one end of the U-shaped support 21. The top end of the damping cotton is fixedly connected to the bottom end of the limiting plate. The lifting and positioning structure is a dumbbell plate groove 25, and the dumbbell plate groove 25 is fixedly connected to the outer wall of one end of the U-shaped support 21. The rotating rod 24 is slidably and tightly clamped between the inner walls of the dumbbell plate groove 25. The clamping and lifting structure is composed of an electric cylinder 230 and a semi-circular arc plate 231 fixedly connected to the top end of the electric cylinder 230. The inner wall of the semi-circular arc plate 231 is rotatably clamped to the outer wall of the rotating rod 24. The bottom end of the electric cylinder 230 is fixedly connected to the outer wall of the top end of the support plate 29.

[0023] Adopting the above solution: The rotating rotating cylinder 23 will drive the brush hair 22 to rotate synchronously. Thus, the brush hair 22 can clean the surface of the bar temporarily clamped in the material groove 13. The frictional force during the cleaning process will drive the bar to rotate, and then the outer wall of the bar can be comprehensively cleaned. Subsequently, the electric cylinder 230 on the support plate 29 can be started to drive the semi-circular arc plate 231 connected to the rotating rod 24 at the top end to move upward, and then drive the rotating rod 24 to move upward and be clamped into the upper half inner wall groove of the dumbbell plate groove 25, extending the distance between the brush hair 22 and the feeder 1. Thus, it can be applicable to the surface cleaning of bars with larger diameter specifications, increasing the versatility.

[0024] The rotating and meshing structure is composed of a first spur gear 26, a second spur gear 27, and a first power source for driving the second spur gear 27 to rotate. The bottom end of the first power source is fixedly connected with a support plate 29. One end of the support plate 29 is fixedly connected to the outer wall of one end of the feeder 1. The first spur gear 26 and the second spur gear 27 can be meshed and connected, and the first spur gear 26 is fixedly connected to the rotating rod 24.

[0025] Adopting the above solution: During the conveying process of the bar, it is also necessary to first start the first power source to drive the spur gear two 27 fixedly connected thereto and the spur gear one 26 meshed with the spur gear two 27 to rotate. Thus, the rotating rod 24 is driven to rotate by the spur gear one 26. Among them, the first power source is specifically the motor 28. The rotating rod 24 will drive the rotating cylinder 23 and the bristles 22 installed on the outer wall of the rotating cylinder 23 to rotate synchronously.

[0026] The rotating and lifting structure consists of a cross bar 281, a disc 282, and a semi-circular pull plate 283 movably sleeved on the disc 282. A U-shaped groove is opened at the bottom end of the semi-circular pull plate 283. The two ends of the cross bar 281 are fixedly connected to the spur gear two 27 and the outer wall of one end of the disc 282 respectively. The lifting limit structure is composed of a lifting plate rod 284, a rotating shaft 285, and a cylinder 286 slidably connected to the outer wall of the lifting plate rod 284. The lifting plate rod 284 and the rotating shaft 285 are rotatably connected. Both ends of the rotating shaft 285 are fixedly connected to the inner wall of the U-shaped groove. The lifting plate rod 284 is in close contact with the inner wall of the U-shaped groove. One end of the cylinder 286 is fixedly connected to the inner wall of one end of the feeder. The bottom end of the lifting plate rod 284 is fixedly connected to one side of the top end of the damping cotton.

[0027] Adopting the above solution: While the motor 28 drives the spur gear two 27 to rotate, it will also drive the cross bar 281 installed at the other end of the spur gear two 27 to rotate. The rotation of the cross bar 281 will drive the disc 282 to rotate in real time. Since the installation position of the cross bar 281 on the disc 282 is close to the edge position of the disc 282, when the disc 282 rotates, it will drive the semi-circular pull plate 283 to perform a short-distance circular rotation, not rotating around the axis, thereby driving the lifting plate rod 284 rotatably connected to the rotating shaft 285 to move up and down. The cylinder 286 is used to limit the lifting plate rod 284, thereby driving the damping surface under the bar to lift up and down by a certain distance, matching the frequency during vibration, and at the same time jointly buffering the impact force and vibration on the bottom of the feeder 1 by the material limiting plate and the spring.

[0028] The lubrication structure includes an air box 291 and a corrugated pipe 292 fixedly connected to the inner wall of the air box 291. A filter screen plate 293 is fixedly connected through the top end of the air box 291. Air nozzles 294 are fixedly connected through the top end and the left and right ends of the air box 291. A check valve 295 is fixedly connected to each air nozzle 294. An oil tank 296 is fixedly connected to the inner wall of the air box 291. A sponge 297 is fixedly connected inside the oil tank 296. Oil holes are formed through the sponge 297 and the bottom end of the air box 291. One end of the rotating rod 24 is fixedly connected with a support rod 298. Cam 299 is fixedly connected to the support rod 298. The cam 299 is in fitting rotational connection between the inner wall of the top end of the air box 291 and the outer wall of the top end of the oil tank 296. The support rod 298 is in close rotational connection between the inner and outer walls of one end of the air box 291. The air box 291 is in close rotational connection with the first power source. The bottom end of the air box 291 is fixedly connected to the top end of the support plate 29.

[0029] With the above solution: When the rotating rod 24 rotates, it will drive the fixedly connected support rod 298 and the cam 299 on the support rod 298 to rotate, thereby hitting the inner wall of the top end of the air box 291 and the outer wall of the top end of the oil tank 296, causing the air box 291 to move upward through the corrugated pipe 292, driving the gas to enter from the top air nozzle 294, and passing the gas through the filter screen plate 293 for sieving to prevent dust from falling and adhering to the first spur gear 26 and the second spur gear 27. At the same time, the filtered clean gas will be discharged through the air nozzles 294 installed on the left and right ends of the air box 291. The check valves 295 on the three air nozzles 294 are used to control the unidirectional output of the gas to ensure the fluidity of the gas inside the air box 291. Then, due to the top of the oil tank 296 being made of rubber material, when it is hit, it will move slightly downward, squeezing the sponge 297 filled with lubricating oil inside, thereby causing the oil to flow downward. Through the small oil holes opened, the oil can slightly fall onto the second spur gear 27 to prevent the first spur gear 26 and the second spur gear 27 from getting stuck and rotating smoothly when meshing and rotating for a long time.

[0030] The material suction structure is composed of a suction pump 232, a delivery pipe 233, a suction pipe 234, a groove plate 235, and a plurality of suction cups 236 fixedly connected to the bottom end of the groove plate 235. The bottom end of the suction pump 232 is fixedly connected to the outer wall of the top end of the U-shaped bracket 21. The two ends of the suction pump 232 are respectively fixedly connected to the delivery pipe 233 and the suction pipe 234. The bottom end of the suction pipe 234 is connected through the top end of the groove plate 235, and the suction pipe 234 is fixedly connected through to the top end of the U-shaped bracket 21.

[0031] Adopt the above solution: During the cleaning process of the bar, the generated debris and dust can synchronously activate the suction pump 232 installed on the U-shaped bracket 21. When the suction pump 232 operates, it sucks the debris and dust through the slot plate 235 on the suction pipe 234 and the multiple suction cups 236 installed at the bottom end of the slot plate 235, so as to keep the feeder 1 and the bar clean and improve the working environment during the feeding process.

[0032] The aggregate structure is composed of a waste box 237 and a lifting frame 238 fixedly connected to both sides of the top end of the waste box 237. The bottom end of the waste box 237 can be closely attached to the outer wall of the top end of the U-shaped bracket 21, and the bottom end of the U-shaped bracket 21 is fixedly connected to the outer wall of the top end of the feeder 1.

[0033] Adopt the above solution: The sucked debris and dust will pass through the conveying pipe 233 at one end of the suction pump 232, and the debris and dust will be introduced into the waste box 237. When the impurities in the waste box 237 need to be cleaned and replaced, only need to manually lift the lifting frame 238 installed on both sides of the waste box 237, and then the waste box 237 can be easily transported and processed.

[0034] It should be added that: the models of the motors 28 are all SJ36500, the control switch and the storage battery are both installed on the feeder 1, the switch wires of the control switch and the storage battery form a complete current loop, and just press the control switch to start the motor 28.

[0035] The working principle and usage process of the present invention: When the bar is passively conveyed by the feeder 1, the limiting plates 11 installed on the inner walls at both ends of the feeder 1 will limit the bar during transportation to prevent excessive deviation during the bar transportation, resulting in blockage and jamming. At the same time, when the bar is limited by the limiting plate 11, the bar will be temporarily rotationally clamped in the material groove 13 opened on the limiting plate 11. Since the limiting plate 11 is made of PU material, when limiting the bar, it can also play a certain buffering effect synchronously. When the limiting plate 11 is squeezed by the bar, the limiting plate 11 will be squeezed against multiple springs 12 for the first time, causing them to deform. Thus, in combination with the limiting plate 11, it buffers the vibration generated during the bar feeding and the impact force on the feeding support, thereby avoiding the vibration and noise generated when the bar collides with the feeder 1. At the same time, during the bar transportation process, it is also necessary to first start the first power source to drive the fixed-connected second spur gear 27 and the first spur gear 26 meshed with the second spur gear 27 to rotate. Thus, the rotating rod 24 is driven to rotate by the first spur gear 26. Among them, the first power source is specifically a motor 28. When the motor 28 drives the second spur gear 27 to rotate, it will also drive the cross bar 281 installed at the other end of the second spur gear 27 to rotate. The rotation of the cross bar 281 will drive the disk 282 to rotate in real time. Since the installation position of the cross bar 281 on the disk 282 is close to the edge position of the disk 282, when the disk 282 rotates, it will drive the semi-circular pull plate 283 to perform a short-distance circular rotation, not rotating around the axis, and further drive the lifting plate rod 284 rotatably connected to the rotating shaft 285 to move up and down. The cylinder 286 is used to limit the lifting plate rod 284, thereby driving the damping surface under the bar to lift up and down at a certain distance, matching the frequency during vibration, and at the same time, in combination with the limiting plate and the spring, buffering the impact force and vibration on the bottom of the feeder 1. The rotating rod 24 in rotation will drive the rotating cylinder 23 and the brush hairs 22 installed on the outer wall of the rotating cylinder 23 to rotate synchronously. Thus, the brush hairs 22 can clean the surface of the bar temporarily clamped in the material groove 13. The frictional force during the cleaning process will drive the bar to rotate, and thus the outer wall of the bar can be comprehensively cleaned. And when the rotating rod 24 rotates, it will also drive the fixed-connected support rod 298 and the cam 299 on the support rod 298 to rotate. Thus, it hits the inner wall of the top end of the air box 291 and the outer wall of the top end of the oil tank 296, causing the air box 291 to move up through the corrugated pipe 292, driving the gas to enter from the top air funnel 294, and passing through the filter screen plate 293 to sieve the gas, avoiding dust from falling and adhering to the first spur gear 26 and the second spur gear 27. At the same time, the clean gas after sieving will be discharged through the air funnels 294 installed on the left and right ends of the air box 291. The one-way valves 295 on the three air funnels 294 are used to control the one-way output of the gas to ensure the fluidity of the gas inside the air box 291. Then, due to the top of the oil tank 296 being made of rubber material, when it is hit, it will move down slightly, squeezing the sponge 297 filled with lubricating oil inside, and thus the oil flows down.Through the opened small oil holes, a small amount of oil can fall onto the second spur gear 27, avoiding jamming and unsmooth rotation when the first spur gear 26 and the second spur gear 27 are engaged and rotated for a long time. Subsequently, the electric cylinder 230 on the support plate 29 can be started to drive the semi-circular arc plate 231 connected to the rotating rod 24 at the top to move upward, thereby driving the rotating rod 24 to move upward and be clamped into the upper inner wall groove of the dumbbell plate groove 25, extending the distance between the brush bristles 22 and the feeder 1. Thus, it can be applied to the surface cleaning of bars with a larger diameter specification, increasing the versatility. At the same time, during the bar cleaning process, the generated debris and dust can synchronously start the suction pump 232 installed on the U-shaped bracket 21. When the suction pump 232 operates, the debris and dust are sucked through the slot plate 235 on the suction pipe 234 and the multiple suction cups 236 installed at the bottom of the slot plate 235 to keep the feeder 1 and the bar clean, improving the working environment during the feeding process. The sucked debris and dust will pass through the delivery pipe 233 at one end of the suction pump 232 to introduce the debris and dust into the waste box 237. When the impurities in the waste box 237 need to be cleaned and replaced, only need to manually lift the lifting frames 238 installed on both sides of the waste box 237, and then the waste box 237 can be easily transported and processed.
