Description

Technical Field

[0001] This application relates to the field of material feeding and conveying technology, and in particular to a fully automatic intermittent feeding device. Background Technology

[0002] In the industrial manufacturing sector, the cutting and conveying of metal tubes are common production processes. With the continuous development of the manufacturing industry, the requirements for efficiency and quality in metal tube processing are also increasing. Efficient, stable, and precise cutting and conveying equipment plays a crucial role in improving production efficiency and ensuring product quality. It not only affects the smooth operation of the production process but also impacts the cost and efficiency of the entire production system. A reasonable cutting and conveying method can reduce manual intervention, lower labor intensity, and avoid errors and accidents caused by human factors. Therefore, the development of advanced cutting and conveying equipment has always been an important research direction in this field.

[0003] In traditional metal pipe unloading and conveying operations, the unloading method typically involves direct dropping of the pipe. This method is relatively simple, relying on the pipe's own weight to fall naturally onto the processing platform. For conveying, when different processing requirements necessitate transferring pipes to different processing platforms, a single-height conveyor belt or a simple inclined chute is generally used. Gravity is used to move the pipe along the conveyor belt or slide it to the designated processing platform. In some cases, manual handling is also employed to transfer the pipe to the appropriate processing platform. These methods, to a certain extent, meet basic production needs and are common in small processing plants or simple production scenarios due to their simplicity and lack of complex equipment and technical support.

[0004] However, the aforementioned material feeding and conveying methods have significant drawbacks. Due to the large mass of the metal pipes, direct feeding generates considerable impact force, which easily damages the round pipes and reduces product quality. Furthermore, existing technology struggles to achieve intermittent feeding. For situations requiring the transfer of different pipe fittings to different processing platforms, it cannot accurately and efficiently perform the classification and conveying function, hindering the proper classification and storage of processed pipe fittings. This severely impacts production efficiency and quality, and warrants improvement. Utility Model Content

[0005] To address the problem of low production efficiency and quality caused by the inability of traditional material feeding equipment to perform intermittent sorting and feeding, this application provides a fully automatic intermittent material feeding device.

[0006] This application provides a fully automatic intermittent feeding device, which adopts the following technical solution:

[0007] A fully automatic intermittent feeding device includes a frame and multiple working units linearly distributed on the frame. Each working unit includes a receiving platform, a conveying mechanism, and a distributing mechanism. The receiving platform is fixed on the frame and is equipped with a buffer mechanism for intercepting metal pipes. The conveying mechanism and the distributing mechanism are sequentially located at the downstream end of the receiving platform and at the upstream end of different processing platforms. The metal pipes on the receiving platform are conveyed to the conveying mechanism and then to the distributing mechanism, forming a first conveying route. The metal pipes on the conveying mechanism are conveyed to the next conveying mechanism, forming a second conveying route. A blocking mechanism is provided between the conveying mechanisms of any two adjacent working units to prevent the metal pipes from being conveyed along the second conveying route to the next conveying mechanism.

[0008] By adopting the above technical solution, multiple working units on the frame can realize the continuous sorting and conveying process of metal tubes; the buffer mechanism set in the receiving platform can intercept the metal tubes to buffer them and prevent them from being deformed by the impact force generated by the direct fall; the conveying mechanism and the sorting mechanism are located at the upstream end of different processing platforms, and together with the first and second conveying routes, they can accurately and efficiently sort and convey the metal tubes to different processing platforms; the blocking mechanism can prevent the metal tubes from being conveyed to the next conveying mechanism along the second conveying route, realizing intermittent sorting and unloading, which is conducive to the classified storage of processed tubes and improves production efficiency and quality.

[0009] Preferably, the buffer mechanism includes buffer links, a link connecting shaft, and a buffer drive cylinder. The link connecting shaft is rotatably mounted on a frame below the receiving platform, and the axis of rotation of the link connecting shaft is parallel to the transmission direction of the second transmission route. Multiple buffer links are evenly spaced along the axial direction on the link connecting shaft, and one end of any buffer link is fixedly connected to the link connecting shaft. The buffer drive cylinder is hinged to the frame below the receiving platform, and the output end of the buffer drive cylinder is hinged to any one of the buffer links on the link connecting shaft. Multiple clearance slots are provided on the receiving platform corresponding to the number and position of the buffer links, and any buffer link can abut against the metal pipe through the clearance slot at the corresponding position.

[0010] By adopting the above technical solution, the buffer drive cylinder drives the connecting shaft to rotate, which in turn drives the buffer connecting rod to move. This allows the buffer connecting rod to abut against the metal tube through the clearance groove, thus buffering and decelerating the falling metal tube, preventing deformation of the metal tube, and improving product quality.

[0011] Preferably, the transmission mechanism includes a transition platform and a transmission roller, and multiple transition platforms are equally spaced along the transmission direction of the second transmission route. Each transition platform is fixed on the frame, and each transition platform is located on the same horizontal plane as the receiving platform. Multiple transmission rollers are arranged on the side of the transition platform away from the receiving platform, corresponding to the number and position of the transition platforms. Each transmission roller is rotatably mounted on the frame, and the rotation axis of each transmission roller is parallel to the transmission direction of the first transmission route. The transmission mechanism also includes a drive component for driving the transmission roller to rotate.

[0012] By adopting the above technical solution, the transition platforms are set at equal intervals along the transmission direction of the second transmission route and are located on the same horizontal plane as the receiving platform, which facilitates the smooth transition of the metal tubes on the receiving platform to the transmission rollers. The transmission rollers are set in multiple positions corresponding to the number of transition platforms, and their rotation axis is parallel to the transmission direction of the first transmission route. With the help of the drive component, the metal tubes can be transmitted along the second transmission route and then transmitted to the transmission mechanism in the next working unit, realizing the function of classifying and transmitting metal tubes and improving production efficiency.

[0013] Preferably, any of the transmission rollers has an annular limiting groove along its axial direction.

[0014] By adopting the above technical solution, an annular limiting groove is opened on the transmission roller of the transmission mechanism, which can limit the metal tube, ensure the stability of the metal tube transmission process, and prevent it from deviating during the transmission process.

[0015] Preferably, the material distribution mechanism includes a receiving plate, a tilting shaft, and a tilting drive cylinder. The tilting shaft is located on the side of the transmission roller away from the transition table and is rotatably mounted on the frame. The rotation axis of the tilting shaft is parallel to the transmission direction of the second transmission route. Multiple receiving plates are provided. One end of any receiving plate is fixedly connected to the tilting shaft, and the other end of any receiving plate is located between any two adjacent transmission rollers. The tilting drive cylinder is hinged to the frame below the receiving plate, and the output end of the tilting drive cylinder is hinged to any one of the receiving plates on the tilting shaft.

[0016] By adopting the above technical solution, the receiving plate, the flipping shaft and the flipping drive cylinder of the material sorting mechanism are combined. The flipping drive cylinder drives the receiving plate to drive the flipping shaft to move, which can realize the unloading action of metal tubes from the transmission roller to the processing platform, realize the automation of the sorting and unloading process, and improve the accuracy and controllability of unloading.

[0017] Preferably, any of the receiving plates has a limiting section along its length.

[0018] By adopting the above technical solution, the limiting cut surface on the receiving plate is opened to further enhance the limiting effect on the metal tube, prevent the metal tube from rolling back during the feeding process, make the feeding process more accurate and stable, and improve production efficiency and quality.

[0019] Preferably, the blocking mechanism includes a blocking plate, a blocking linkage, and a blocking drive cylinder. The blocking plate is fixed to one end of the blocking linkage, and the other end of the blocking linkage is rotatably mounted on the frame. The rotation axis of the end of the blocking linkage is parallel to the transmission direction of the first transmission route. The blocking drive cylinder is hinged to the frame, and the output end of the blocking drive cylinder is hinged to the blocking linkage.

[0020] By adopting the above technical solution, the blocking drive cylinder drives the blocking linkage to rotate, thereby driving the blocking plate to move, which can block the metal tube from being transmitted along the second transmission route to the next transmission mechanism, realize intermittent classification and feeding, and accurately control the transmission of metal tubes in different working units.

[0021] Preferably, any of the transmission rollers is fitted with a protective sleeve, and the protective sleeve is provided with anti-slip protrusions.

[0022] By adopting the above technical solution, the protective sleeve can protect the metal tube and prevent damage caused by direct contact between the transmission roller and the metal tube; the anti-slip protrusions on the protective sleeve can increase the friction between the transmission roller and the metal tube, making the metal tube more stable and less prone to slipping during transmission, and ensuring that the feeding equipment can transmit the metal tube more reliably.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The buffer mechanism on the receiving platform buffers and decelerates the falling metal pipe, preventing the metal pipe from deforming due to the large impact force generated by the direct drop, thus ensuring product quality.

[0025] 2. The transmission mechanism, material sorting mechanism, and barrier mechanism work together to achieve intermittent classified material feeding and precise and efficient classified transmission, which is conducive to the classified storage of processed pipe fittings and improves production efficiency and quality;

[0026] 3. Multiple work units are linearly distributed on the frame, which can continuously feed and transport metal tubes, further improving production efficiency. Attached Figure Description

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail.

[0033] This application discloses a fully automatic intermittent feeding device.

[0034] Reference Figure 1 A fully automatic intermittent feeding device includes a frame 1 and multiple working units 2 linearly distributed on the frame 1. In this embodiment, two working units 2 are provided. Each working unit 2 includes a receiving platform 21, a conveying mechanism 22, and a distributing mechanism 23. The receiving platform 21 is fixedly connected to the frame 1 by bolts, and a buffer mechanism 24 for intercepting metal pipes is provided on the receiving platform 21. The conveying mechanism 22 and the distributing mechanism 23 are sequentially arranged at the downstream end of the receiving platform 21, and the conveying mechanism 22 and the distributing mechanism 23 are respectively located at... At the upstream end of different processing platforms, in this embodiment, the transmission mechanism 22 and the unloading mechanism are arranged horizontally and from near to far between the receiving platform 21 and the processing platform; the metal pipe on the receiving platform 21 is transmitted to the transmission mechanism 22 and then to the material distribution mechanism 23 as the first transmission route, and the metal pipe on the transmission mechanism 22 is transmitted to the next transmission mechanism 22 as the second transmission route. A blocking mechanism 3 is provided between any two adjacent transmission mechanisms 22 of the working unit 2 to prevent the metal pipe from being transmitted to the next transmission mechanism 22 along the second transmission route.

[0035] In practical use, the linearly distributed working unit 2 can realize continuous classification and automatic unloading; the receiving platform 21 receives the falling metal pipes, and the buffer mechanism 24 can intercept and buffer the metal pipes on the receiving platform 21 to prevent the metal pipes from being deformed due to excessive speed; the transmission mechanism 22 can transmit the metal pipes that have decelerated and slid down from the receiving platform 21 to the transmission mechanism 22 of the next working unit 2 along the second transmission route; the sorting mechanism 23 can accurately classify and unload the metal pipes to the processing platform along the first transmission route; the blocking mechanism 3 can block the metal pipes from being transmitted to the next transmission mechanism 22 along the second transmission route, realizing intermittent material storage and classification unloading in combination with the first transmission route.

[0036] Reference Figure 1 The blocking mechanism 3 includes a blocking plate 31, a blocking connecting rod 32, and a blocking drive cylinder 33. The blocking plate 31 is fixed to one end of the blocking connecting rod 32, and the other end of the blocking connecting rod 32 is rotatably mounted on the frame 1. The rotation axis of the end of the blocking connecting rod 32 is parallel to the transmission direction of the first transmission route. The blocking drive cylinder 33 is hinged to the frame 1, and the output end of the blocking drive cylinder 33 is hinged to the blocking connecting rod 32. In this embodiment, the blocking connecting rod 32 is U-shaped. The blocking plate 31 is fixedly connected to one end of the blocking connecting rod 32 by welding, and the output end of the blocking drive cylinder 33 is hinged to the middle part of the blocking connecting rod 32. A support shaft 11 is fixedly connected to the frame 1 by welding, and the end of the support shaft 11 away from the frame 1 passes through the end of the blocking connecting rod 32 away from the blocking plate 31 to form a rotational fit.

[0037] In actual use, when the blocking drive cylinder 33 in the blocking mechanism 3 drives the blocking link 32 to rise, the blocking link 32 drives the blocking plate 31 to rise, so that the blocking plate 31 abuts against the end of the metal tube on the transmission mechanism 22, thereby blocking the metal tube from being transmitted along the second transmission route to the transmission mechanism 22 of the next working unit 2. Then, in conjunction with the material sorting mechanism 23, the metal tube is sorted and unloaded onto the processing platform along the first transmission route. When the blocking drive cylinder 33 in the blocking mechanism 3 drives the blocking plate 31 to fall, the blocking link 32 drives the blocking plate 31 to fall. At this time, the metal tube on the transmission mechanism 22 can be normally transmitted to the next transmission mechanism 22 along the second transmission route.

[0038] Reference Figure 1 and Figure 2The buffer mechanism 24 includes buffer connecting rods 241, connecting rod connecting shafts 242, and buffer drive cylinders 243. Both ends of the connecting rod connecting shaft 242 are rotatably connected to the frame 1 below the receiving platform 21 via bearings. The rotation axis of the connecting rod connecting shaft 242 is parallel to the transmission direction of the second transmission route. Multiple buffer connecting rods 241 are evenly spaced along the axial direction of the connecting rod connecting shaft 242, and one end of each buffer connecting rod 241 is fixedly connected to the connecting rod connecting shaft 242. The buffer drive cylinder 243 is hinged to the frame 1 below the receiving platform 21. The output end of cylinder 243 is hinged to any one of the buffer connecting rods 241 on the connecting rod shaft 242. In this embodiment, there are three buffer connecting rods 241. Each buffer connecting rod 241 is arranged in an "L" shape, and the output end of the buffer drive cylinder 243 is hinged to the corner of any one of the buffer connecting rods 241 on the connecting rod shaft 242. The receiving platform 21 is provided with multiple clearance grooves 211 corresponding to the number and position of the buffer connecting rods 241. In this embodiment, there are three clearance grooves 211, and any one of the buffer connecting rods 241 can abut against the metal pipe through the clearance groove 211 at the corresponding position.

[0039] In actual use, the buffer drive cylinder 243 in the buffer mechanism 24 drives the buffer connecting rod 241 hinged to it to rotate, which can drive all the buffer connecting rods 241 on the connecting rod connecting shaft 242 to rotate. When the buffer drive cylinder 243 drives the buffer connecting rod 241 to rise, the buffer connecting rod 241 can pass through the relief groove 211 and abut against the falling metal tube to prevent the metal tube from being deformed by impact. Then the buffer drive cylinder 243 drives the buffer connecting rod 241 to descend, release the metal tube again, and let it slowly slide down to the transmission mechanism 22 for transmission or unloading.

[0040] Reference Figure 1 and Figure 3 The transmission mechanism 22 includes a transition platform 221 and a transmission roller 222. Multiple transition platforms 221 are evenly spaced along the transmission direction of the second transmission route. In this embodiment, four transition platforms 221 are provided. Each transition platform 221 is fixedly connected to the frame 1 by welding, and each transition platform 221 is located on the same horizontal plane as the receiving platform 21. Multiple transmission rollers 222 are located on the side of the transition platform 221 away from the receiving platform 21, corresponding to the number and position of the transition platforms 221. Each transmission roller 222 is rotatably mounted on the frame 1, and the rotation axis of each transmission roller 222 is parallel to the transmission direction of the first transmission route. In this embodiment, four transmission rollers 222 are provided. One end of each transmission roller 222 near the transition platform 221 is rotatably connected to the frame 1 below the transition platform 221 via a bearing, and the other end of each transmission roller 222 is rotatably connected to the frame 1 near the material distribution mechanism 23 via a bearing.

[0041] Reference Figure 1 and Figure 3 The transmission mechanism 22 further includes a drive assembly 223 for driving the transmission roller 222 to rotate. In this embodiment, the drive assembly 223 is located on the side of the transition platform 221 away from the transmission roller 222. The drive assembly 223 includes a drive sprocket 2231, a transmission sprocket 2232, a chain 2233, and a drive motor 2234 fixedly connected to the frame 1 by bolts. Four drive sprockets 2231 are arranged corresponding to the number and position of the transmission rollers 222, and the end of each transmission roller 222 near the transition platform 221 passes through a bearing and is coaxially fixedly connected to the drive sprocket 2231. Five transmission sprockets 2232 are provided, and the rotation axis of any one of the transmission sprockets 2232 is parallel to the rotation axis of the drive sprocket 2231. One of the five transmission sprockets 2232 is coaxially and fixedly connected to the output shaft of the drive motor 2234. The other four transmission sprockets 2232 are coaxially and fixedly connected to the rotating shafts 2235. The end of any rotating shaft 2235 away from the transmission gear is rotatably connected to the frame 1 through a bearing. The chain 2233 is wound around the drive sprocket 2231 and the transmission sprocket 2232, and keeps the drive sprocket 2231 and the transmission sprocket 2232 rotating synchronously.

[0042] In actual use, the transition table 221 smoothly transfers the metal tube on the receiving platform 21 to the transmission roller 222. The drive motor 2234 in the drive assembly 223 drives the transmission sprocket 2232, which is fixed to the same axis, to rotate. This drives the other transmission sprockets 2232 and all drive sprockets 2231 to rotate synchronously, thereby driving multiple transmission rollers 222 to rotate synchronously. This enables the metal tube to be transferred along the second transmission route to the transmission mechanism 22 in the next working unit 2. Subsequently, it is combined with the material sorting mechanism 23 to sort and unload the material along the first transmission route to the processing platform.

[0043] Reference Figure 1 and Figure 3The material distribution mechanism 23 includes a receiving plate 231, a tilting shaft 232, and a tilting drive cylinder 233. The tilting shaft 232 is located on the side of the conveyor roller 222 away from the transition table 221. Both ends of the tilting shaft 232 are rotatably connected to the frame 1 via bearings, and the rotation axis of the tilting shaft 232 is parallel to the transmission direction of the second transmission route. Multiple receiving plates 231 are provided; in this embodiment, three receiving plates 231 are provided. Any one of the receiving plates 231... One end of the receiving plate 231 is fixedly connected to the flipping shaft 232, and the other end of any of the receiving plates 231 is located between any two adjacent transmission rollers 222. The flipping drive cylinder 233 is hinged to the frame 1 below the receiving plate 231, and the output end of the flipping drive cylinder 233 is hinged to any of the receiving plates 231 on the flipping shaft 232. A limiting cut surface 2311 is provided on any of the receiving plates 231 along its length direction, and in the embodiment of this application, the limiting cut surface 2311 is arranged in a "V" shape.

[0044] In practical use, the flipping drive cylinder 233 in the sorting mechanism 23 drives the receiving plate 231 hinged to it to rotate, which in turn drives all the receiving plates 231 on the flipping shaft 232 to rotate. When the flipping drive cylinder 233 drives the receiving plate 231 to rise, the metal tube falls from the transmission roller 222 onto the receiving plate 231. As the tilt angle of the receiving plate 231 gradually rises, the metal tube falls to the processing platform to complete the unloading. Then the flipping drive cylinder 233 drives the receiving plate 231 to fall. When there are metal tubes on the transmission roller 222 that need to be sorted and unloaded along the first transmission route, the flipping is performed again. The limiting cut surface 2311 on the receiving plate 231 prevents the metal tube from rolling back during the unloading process, making the unloading process more accurate and stable.

[0045] Reference Figure 4 An annular limiting groove 2221 is provided on any of the transmission rollers 222 along its axial direction. In this embodiment, the transmission roller 222 with the annular limiting groove 2221 is arranged in an hourglass shape. In actual use, the annular limiting groove 2221 can limit the metal tube, ensure the stability of the metal tube transmission process, and prevent it from deviating during the transmission process.

[0046] Reference Figure 4 Each of the transmission rollers 222 is fitted with a protective sleeve 2222, and the protective sleeve 2222 is provided with anti-slip protrusions 2223. In this embodiment of the application, the protective sleeve 2222 is made of rubber, and multiple anti-slip protrusions 2223 are provided. In actual use, the rubber protective sleeve 2222 can prevent the transmission roller 222 from directly contacting the metal tube and causing damage, while the anti-slip protrusions 2223 can increase the friction between the transmission roller 222 and the metal tube, making the metal tube more stable and less prone to slipping during transmission.

[0047] The implementation principle of this application embodiment is as follows: the linearly distributed working units 2 on the frame 1 work together to achieve continuous sorting and automatic unloading; the receiving platform 21 receives the falling metal tube, and the buffer drive cylinder 243 in the buffer mechanism 24 drives the buffer connecting rod 241 to rotate, and the metal tube is intercepted and buffered by the avoidance groove 211 to prevent inertial impact deformation caused by excessive unloading distance. Then, the buffer drive cylinder 243 drives the buffer connecting rod 241 to descend, and the metal tube slides to the transition platform 221 in the transmission mechanism 22 and smoothly transitions to the transmission roller 222; then the drive... The motor 2234 drives the transmission roller 222 to rotate through the drive sprocket 2232, drive sprocket 2231 and chain 2233, so as to transport the metal tube to the next working unit 2 along the second transmission route. At the same time, the annular limiting groove 2221 on the transmission roller 222 prevents the metal tube from deviating during transmission, so that the metal tube is transported stably along the second transmission route. The protective sleeve 2222 can prevent the transmission roller 222 from directly contacting the metal tube and causing damage. The anti-slip protrusion 2223 can increase the friction between the transmission roller 222 and the metal tube, so that the metal tube is more stable during the transmission process.

[0048] When the metal tube is transported to the appropriate position along the second transmission route and needs to be unloaded, the blocking drive cylinder 33 in the blocking mechanism 3 drives the blocking connecting rod 32 to rise, thereby driving the blocking plate 31 to rise and abut against the end of the metal tube, blocking the metal tube from being transported along the second transmission route to the next working unit 2. At the same time, the flipping drive cylinder 233 in the material distribution mechanism 23 drives the receiving plate 231 to rise, and the metal tube falls from the transmission roller 222 to the receiving plate 231. As the receiving plate 231 tilts and rises, the metal tube slides down along the first transmission route to the processing platform. The limiting cut surface 2311 on the receiving plate 231 can prevent the metal tube from rolling back, making the unloading process more accurate and stable.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
