Description

Technical Field

[0001] This application relates to the field of pipe grinding, and in particular to a football goal pipe notch grinding device and processing method. Background Art

[0002] The goal is mainly composed of welding metal rods to each other. It has high structural strength and can withstand the high-speed impact of the ball. However, due to its large volume and fixed shape, it is difficult to store and move. Usually, it is placed at a fixed position on the sports field for athletes to practice or compete. It is difficult for athletes to set up the goal by themselves at non-sports field locations for practice.

[0003] To solve this problem, in the related art, the goal can use joints to assemble several pipes into a goal. The disassembled pipes and joints can not only greatly reduce the storage space, but also be more conducive to handling, making it convenient for athletes to set up the goal by themselves at locations outside the sports field for practice. However, during the production process of the pipes, the pipes cut into specific lengths usually need to be ground at both ends to remove burrs and better connect with the joints.

[0004] However, the two ends of the pipes usually need to be ground by workers holding grinding wheels, resulting in low work efficiency. Summary of the Invention

[0005] To improve work efficiency, this application provides a football goal pipe notch grinding device and processing method.

[0006] In a first aspect, this application provides a football goal pipe notch grinding device, adopting the following technical solution:

[0007] A football goal pipe notch grinding device includes a support frame and a guiding mechanism, a transition mechanism, a conveying mechanism, and a grinding mechanism sequentially arranged on the support frame;

[0008] Guiding mechanism: includes an inclined guiding plate;

[0009] Transition mechanism: includes a scraper conveyor that is gradually inclined upward along the direction away from the guiding mechanism, and the guiding plate is gradually inclined downward along the direction close to the scraper conveyor;

[0010] Conveying mechanism: is horizontally arranged along the direction away from the scraper conveyor, and the pipe located on the conveying mechanism is arranged perpendicular to the conveying direction of the conveying mechanism;

[0011] Grinding mechanism: includes two grinding wheels and a driving motor for driving each grinding wheel to rotate. The two grinding wheels are distributed along the direction perpendicular to the conveying direction of the conveying mechanism, and each grinding wheel is used to grind the corresponding end of the pipe.

[0012] By adopting the above technical solution, the pipe first passes through the inclined guide plate, gradually descends along the guide plate and smoothly transitions to the scraper conveyor. The scraper conveyor gradually slopes upward in the direction away from the guiding mechanism to ensure that the pipe can smoothly move from the guide plate to the scraper conveyor, and then falls onto the conveying mechanism from the side of the scraper conveyor close to the conveying mechanism. When the pipe falls onto the conveying mechanism perpendicular to the conveying direction of the conveying mechanism, subsequently, the conveying mechanism accurately conveys the pipe to the grinding mechanism, and two grinding wheels respectively perform efficient grinding on both ends of the pipe to ensure that the cut of the pipe is smooth and flat. During the whole process, each component works in coordination, improving the work efficiency and grinding quality.

[0013] Optionally, the conveying mechanism includes two limiting plates fixedly connected to the support frame. An fixing plate is fixedly connected between the two limiting plates. The fixing plate is located at one end of each limiting plate close to the scraper conveyor. On one side of each limiting plate close to the fixing plate, there are screw shafts arranged in parallel. One end of each screw shaft is rotatably connected to the fixing plate. A conveying motor for driving each screw shaft to rotate synchronously is fixedly connected to the fixing plate. Screw blades are fixedly connected to the outer side of each screw shaft. One grinding wheel corresponds to one screw shaft, and the grinding wheel is located at the end of the screw shaft away from the fixing plate. A sliding plate is fixedly connected to the support frame. One end of the sliding plate is fixedly connected to the fixing plate, and the other end slopes upward in the direction close to the scraper conveyor.

[0014] By adopting the above technical solution, after the pipe on the scraper conveyor moves to the side of the scraper conveyor close to the conveying mechanism, the pipe drops downward onto the sliding plate, and then slides along the sliding plate to one side of the two screw shafts. Each end of the pipe is lapped on a corresponding screw shaft. During this process, each screw shaft rotates synchronously under the drive of the conveying motor, thereby driving the screw blades to rotate, so as to stably push the pipe forward. When the pipe reaches the end of the conveying mechanism, two grinding wheels respectively perform grinding treatment on the cuts at both ends of the pipe to ensure that the cuts are flat and smooth. At the same time, the design of the sliding plate enables the pipe to smoothly transition to the next process, improving the work efficiency and stability of the entire equipment.

[0015] Optionally, upper limit plates are connected to the mutually approaching surfaces of the two limiting plates. The upper limit plates are located above the screw shafts. An inlet is provided between each upper limit plate and the fixing plate. A limiting plate is fixedly connected to the upper surface of one end of the upper limit plate close to the inlet.

[0016] By adopting the above technical solution, the upper limit plates can effectively reduce the occurrence of jumping or offset of the pipe during the conveying process, ensuring that the pipe smoothly enters the grinding station. The design of the inlet enables the pipe to smoothly enter the space between the limiting plates, ensuring that each end of the pipe is lapped on a corresponding screw shaft.

[0017] Optionally, vertical chutes are provided on the side surfaces of the two limiting plates facing each other. A slider is fixedly connected to one side surface of each upper limiting plate, and the slider is slidably connected to the chute. A support rod is fixedly connected to the upper end of each limiting plate. A screw rod is threadedly connected to the support rod. The lower end of the screw rod is rotatably connected to the upper limiting plate, and a hand wheel is fixedly connected to the upper end of the screw rod.

[0018] By adopting the above technical solution, the cooperation between the chute provided on the limiting plate and the slider on the upper limiting plate realizes the height adjustment function of the upper limiting plate, ensuring that the upper limiting plate can adapt to pipes of different diameters and improving the applicability of the equipment. At the same time, the screw rod on the support rod is rotatably connected to the upper limiting plate and is operated by a hand wheel, facilitating the user to quickly adjust the position of the upper limiting plate.

[0019] Optionally, a limiting block is rotatably connected to one end of each auger shaft away from the fixed plate. The auger shaft includes a conveying section and a receiving section. The auger blade is installed on the conveying section. The receiving section is located at one end of the auger shaft close to the limiting block. Each grinding wheel is aligned with a corresponding receiving section.

[0020] By adopting the above technical solution, since the auger blade is provided on the conveying section, the pipe is conveyed along the conveying section. When the pipe moves from the conveying section to the receiving section, it is difficult for the auger shaft to drive the pipe forward at this time, facilitating the grinding mechanism to grind the pipe in the receiving section. And the setting of the limiting block restricts the occurrence of the pipe accidentally breaking away from the receiving section. When the next pipe is conveyed to the receiving section, the next pipe will squeeze and push the previous pipe in the direction of the limiting block. Therefore, the previous pipe that has been ground crosses the limiting block and disengages from the conveying mechanism, thus completing the grinding of the pipe.

[0021] Optionally, the scraper conveyor includes two mounting plates fixedly connected to the support frame. Two sprockets are rotatably connected to the side surfaces of the two mounting plates facing each other. The same chain is installed on the two sprockets on the same mounting plate. A rotating shaft is fixedly connected between each sprocket and one of the sprockets on the other mounting plate. A conveying motor for driving one of the sprockets to rotate is fixedly connected to one of the mounting plates. A plurality of conveying rods are fixedly connected between the two chains. A conveying plate for conveying the pipe is fixedly connected to each conveying rod.

[0022] By adopting the above technical solution, driven by the conveying motor, a plurality of conveying rods and the conveying plates thereon move synchronously. When the pipe enters the transition mechanism from the guiding mechanism, each pipe can slide onto a corresponding conveying plate. Subsequently, the scraper conveyor can accurately push the pipes to the conveying mechanism one by one, ensuring that each pipe remains stable during the transmission process.

[0023] Optionally, tension sprockets are respectively rotatably connected to one side of the two mounting plates close to each other. A rotating shaft is also fixedly connected between the two tension sprockets. Each chain bypasses the corresponding tension sprocket. One side of each chain close to the conveying mechanism is gradually inclined in the direction close to the conveying mechanism. Through holes are formed in each conveying rod, and each conveying plate is damping inserted into the corresponding through hole. The scraper conveyor includes a retraction assembly for pulling the conveying plate on the side close to the conveying mechanism to move away from the conveying mechanism, and the scraper conveyor further includes a reset assembly for pushing the conveying plate on the lower side of the scraper conveyor to move downward.

[0024] By adopting the above technical solution, the tension sprockets can effectively maintain the tension state of the chain, ensuring the transmission stability and reliability. When the pipe moves to the side of the scraper conveyor close to the conveying mechanism, since the side of the scraper conveyor close to the conveying mechanism is also inclined, the pipe does not directly fall from the upper end of the scraper conveyor. Instead, when the corresponding conveying rod and conveying plate move to a position close to the retraction assembly, the retraction assembly pulls the conveying plate on the corresponding conveying rod to move away from the conveying mechanism. At this time, the pipe on the conveying plate will fall onto the conveying mechanism, reducing the occurrence of damage caused by the pipe directly falling from a high place. As the scraper conveyor continues to move, when the conveying plate moving under the drive of the retraction mechanism passes through the reset assembly, the reset assembly pushes the conveying plate downward to reset, facilitating the conveying plate to continue to receive and convey the next pipe.

[0025] Optionally, the retraction mechanism includes magnet blocks fixedly connected between the two mounting plates. Limiting steel plates are fixedly connected to one side of each conveying plate close to the inner ring of the chain. The magnet blocks are located inside the inner ring of the chain and are arranged in the direction close to the conveying mechanism. The magnet blocks are used to adsorb the adjacent limiting steel plates to move in the direction close to the magnet blocks.

[0026] By adopting the above technical solution, when the conveying plate moves to a position close to the magnet block, the magnet block can effectively adsorb the limiting steel plate, and the limiting steel plate drives the conveying plate to move away from the conveying mechanism, thus completing the unloading of the pipe on the scraper conveyor.

[0027] Optionally, the reset assembly includes a receiving plate fixedly connected between the two mounting plates. A driving cylinder is fixedly connected to the receiving plate. The piston rod of the driving cylinder is vertically downward and fixedly connected with an arc-shaped plate. The middle part of the arc-shaped plate gradually bulges downward. When the scraper conveyor rotates, the conveying plate close to the arc-shaped plate gradually extends downward from the corresponding conveying rod along the lower surface of the arc-shaped plate.

[0028] By adopting the above technical solution, when the conveying plate moving under the drive of the retraction mechanism passes through the reset component, the conveying plate moves along the lower surface of the arc plate, and thus moves downward and resets under the push of the arc plate. When part of the conveying plate does not need to be reset, the cylinder is started to drive the arc plate to move upward. At this time, the arc plate is far away from the conveying plate and cannot push the conveying plate to reset. In this way, the number of conveying plates for reset can be adjusted according to requirements, and then the number of conveying plates for conveying pipes can be adjusted.

[0029] In a second aspect, the present application provides a processing method for a football goal pipe cutting and grinding device, adopting the following technical solution:

[0030] A processing method for a football goal pipe cutting and grinding device includes the following steps:

[0031] S1. Cut the pipe;

[0032] S2. Intermittently push the pipe into the transition mechanism along the guiding mechanism;

[0033] S3. The transition mechanism intermittently provides pipes to the conveying mechanism;

[0034] S4. The pipe is transported along the conveying mechanism to the grinding mechanism for grinding.

[0035] By adopting the above technical solution, the football goal pipe cutting and grinding device can realize efficient and stable pipe transmission and grinding processes, and has a high working efficiency.

[0036] In summary, the present application includes at least one of the following beneficial technical effects:

[0037] Each component works together to improve the working efficiency and grinding quality;

[0038] The height adjustment function of the upper limit plate is realized to ensure that the upper limit plate can adapt to pipes with different diameters;

[0039] Adjust the number of conveying plates for reset according to requirements, and then adjust the number of conveying plates for conveying pipes. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0046] The following further describes the present application in detail Figures 1-5 with reference to the accompanying drawings. Embodiment 1

[0047] An embodiment of the present application discloses a football goal pipe cutting and grinding device. Referring to Figure 1 and Figure 2 , the grinding device includes a support frame 1 and a guiding mechanism 2, a transition mechanism 3, a conveying mechanism 4, and a grinding mechanism 5 sequentially installed on the support frame 1. The pipe is transported along the guiding mechanism 2, the transition mechanism 3, and the conveying mechanism 4 to the grinding mechanism 5, and then the two ends of the pipe are ground.

[0048] Among them, the guiding mechanism 2 includes a guiding plate 21 fixedly connected to the support frame 1, and the guiding plate 21 gradually inclines downward in the direction close to the transition mechanism 3. Baffles 22 are respectively fixedly connected to both sides of the guiding plate 21, and the two baffles 22 are arranged vertically upward. The baffles 22 are used to prevent the steel pipe from detaching from the guiding plate 21 on both sides of the guiding plate 21.

[0049] Referring to Figure 1 and Figure 2 , the transition mechanism 3 includes a scraper conveyor 31 that gradually inclines upward in the direction away from the guiding mechanism 2. The scraper conveyor 31 includes two mounting plates 311, each mounting plate 311 is fixedly connected to the support frame 1, one mounting plate 311 corresponds to one baffle 22, and each baffle 22 is fixedly connected to the corresponding mounting plate 311.

[0050] On one side of the two mounting plates 311 close to each other, two sprockets 312 are rotatably connected. The two sprockets 312 are arranged vertically. On the two sprockets 312 on the same mounting plate 311, the same chain 313 is installed. A rotating shaft 314 is fixedly connected between each sprocket 312 and one of the sprockets 312 on the other mounting plate 311. On one side of one of the mounting plates 311 facing away from the sprocket 312, a conveying motor 315 is fixedly connected. The output shaft of the conveying motor 315 penetrates through the corresponding mounting plate 311 and is coaxially fixed with one of the sprockets 312.

[0051] A number of conveying rods 316 are fixedly connected between the two chains 313. A conveying plate 32 for conveying pipes is fixedly connected to each conveying rod 316. A long strip hole 211 for the conveying plate 32 to pass through is formed in the guide plate 21.

[0052] The pipes after being cut are slid along the guide plate 21 in the direction close to the scraper conveyor 31, and then are lapped on one of the conveying plates 32. During the process of the conveying motor 315 driving the two chains 313 to rotate, a number of conveying rods 316 and the conveying plates 32 all move together, and the pipes are transported from the side of the scraper conveyor 31 close to the guiding mechanism 2 to the side of the scraper conveyor 31 close to the conveying mechanism 4, and fall from the side of the scraper conveyor 31 close to the conveying mechanism 4 to the conveying mechanism 4.

[0053] Refer to Figure 2 and Figure 3 As shown in FIGS. and, the conveying mechanism 4 is horizontally arranged in the direction away from the scraper conveyor 31. The pipes located on the conveying mechanism 4 are arranged perpendicular to the conveying direction of the conveying mechanism 4. The conveying mechanism 4 includes two limiting plates 41 fixedly connected to the support frame 1. A fixed plate 42 is fixedly connected between the two limiting plates 41. The fixed plate 42 is located at one end of each limiting plate 41 close to the scraper conveyor 31.

[0054] On one side of each limiting plate 41 close to the fixed plate 42, there are auger shafts 43 arranged in parallel. The auger shafts 43 are arranged along the length direction of the limiting plates 41. One end of each auger shaft 43 is rotatably connected to the fixed plate 42. On the side of the fixed plate 42 away from the auger shafts 43, two conveying motors 44 are fixedly connected. One conveying motor 44 corresponds to one auger shaft 43, and the output shaft of the conveying motor 44 penetrates through the fixed plate 42 and is coaxially fixed with the auger shaft 43.

[0055] Refer to Figure 2 and Figure 3, the conveying mechanism 4 is horizontally arranged in a direction away from the scraper conveyor 31. Each auger shaft 43 on the conveying mechanism 4 includes a conveying section 431 and a receiving section 432. A spiral blade 45 is fixedly connected to the outside of the conveying section 431. The receiving section 432 is located at one end of the conveying section 431 close to the grinding mechanism 5, and a limiting block 46 is rotatably connected to one end of the receiving section 432 away from the conveying section 431. The diameter of the limiting block 46 is larger than that of the receiving section 432.

[0056] The grinding mechanism 5 includes two grinding wheels 51 and a driving motor 52 for driving each grinding wheel 51 to rotate. Each driving motor 52 is fixedly connected to the side surface of the corresponding limiting plate 41 facing away from the auger shaft 43. The vertical shaft of the driving motor 52 is arranged parallel to the receiving section 432, and the output shaft of the driving motor 52 is coaxially fixed to the corresponding grinding wheel 51. One grinding wheel 51 is aligned with one receiving section 432. After the pipe is conveyed to the receiving section 432 along the conveying section 431, each grinding wheel 51 is used to grind the corresponding end of the pipe.

[0057] Two sliding plates 6 are fixedly connected to the support frame 1. One end of each sliding plate 6 is fixedly connected to the fixing plate 42, and the other end is inclined upward in the direction close to the scraper conveyor 31. The function of the sliding plate 6 is to play a buffering and guiding role when the pipe falls from the scraper conveyor 31 to the conveying mechanism 4, reduce the damage to the auger shaft 43 caused by the pipe directly hitting the auger shaft 43, and enable the pipe to smoothly slide along the two sliding plates 6 to the auger shaft 43.

[0058] When the pipe falls onto the conveying mechanism 4 along the sliding plate 6, each end of the pipe is lapped on a corresponding auger shaft 43. The two driving motors 52 are synchronously started to drive the corresponding auger shafts 43 to rotate. In this way, the pipe can be smoothly conveyed to the receiving section 432 for grinding. The limiting block 46 at the receiving section 432 restricts the situation where the pipe to be ground breaks away from the receiving section 432. When the next pipe to be ground is conveyed to the receiving section 432 along the auger shaft 43, the next pipe squeezes and pushes the ground pipe, so that the ground pipe can cross the limiting block 46 and then break away from the conveying mechanism 4.

[0059] Upper limit plates 47 are connected to the mutually close surfaces of the two limiting plates 41. The upper limit plates 47 are located above the auger shafts 43. An inlet 471 is provided between one end of each upper limit plate 47 and the fixing plate 42. The inlet 471 is for the pipe to slide down onto the auger shaft 43. A limiting plate 48 is fixedly connected to the upper surface of one end of the upper limit plate 47 close to the inlet 471. The limiting plate 48 is used to limit the pipe from sliding down onto the upper limit plate 47.

[0060] On one side of each of the two limiting plates 41 close to each other, two vertically arranged sliding grooves 411 are provided. On one side of each upper limiting plate 47, two sliding blocks are fixedly connected. One sliding block corresponds to one sliding groove 411, and the sliding block is slidably connected to the sliding groove 411. At the upper end of each limiting plate 41, two support rods 49 are fixedly connected. On each support rod 49, a screw rod 491 is threadedly connected. The lower ends of the screw rods 491 are rotatably connected to the upper limiting plate 47, and the upper ends of the screw rods 491 are fixedly connected with hand wheels 492.

[0061] By rotating the hand wheel 492, the screw rod 491 is driven to rotate. The screw rod 491 rotates and moves up and down to drive the upper limiting plate 47 to move up and down, so that the upper limiting plate 47 adapts to pipes with different diameters between the auger shafts 43.

[0062] The present application also provides a processing method for a football goal pipe cutting and grinding device, including the following steps:

[0063] S1. Cut the pipe;

[0064] S2. Intermittently push the pipe along the guiding mechanism 2 into the transition mechanism 3;

[0065] S3. The transition mechanism 3 intermittently provides pipes to the conveying mechanism 4;

[0066] S4. The pipe is transported along the conveying mechanism 4 to the grinding mechanism 5 for grinding. Embodiment 2

[0067] The embodiment of the present application discloses a football goal pipe cutting and grinding device. Referring to Figure 1 and Figure 4 , the difference between this embodiment and the above embodiment is that on one side of each of the two mounting plates 311 close to each other, a tensioning sprocket 7 is also rotatably connected respectively. Referring to Figure 2 and Figure 4 , a rotating shaft 314 is also fixedly connected between the two tensioning sprockets 7. Each chain 313 bypasses the corresponding tensioning sprocket 7. The setting of the tensioning sprocket 7 makes one side of each chain 313 close to the conveying mechanism 4 gradually incline in the direction close to the conveying mechanism 4.

[0068] Referring to Figure 4 and Figure 5 , through holes 3161 are provided on each conveying rod 316. Each conveying plate 32 is dampingly inserted into the corresponding through hole 3161, that is, when there is no external force to push the conveying plate 32, the conveying plate 32 and the conveying rod 316 remain relatively stationary. On one side of the conveying plate 32 close to the inner ring of the chain 313, a limiting steel plate 321 is fixedly connected. On one side of the conveying plate 32 away from the inner ring of the chain 313, a stop strip 322 is fixedly connected. The limiting steel plate 321 and the stop strip 322 are both used to prevent the conveying plate 32 from detaching from the conveying rod 316.

[0069] The scraper conveyor 31 includes a retraction assembly 8 that pulls the conveying plate 32 near one side of the conveying mechanism 4 to move away from the conveying mechanism 4, and the scraper conveyor 31 further includes a reset assembly 9 that pushes the conveying plate 32 on the lower side of the scraper conveyor 31 to move downward.

[0070] The retraction assembly 8 includes a magnet block 81 fixedly connected between two mounting plates 311. The magnet block 81 is located inside the inner ring of the chain 313 and close to the conveying mechanism 4.

[0071] When the chain 313 drives the conveying rod 316 and the conveying plate 32 to rotate, after the conveying plate 32 rotates 180 degrees driven by the chain 313 and the conveying rod 316, the pipe drops from the original conveying plate 32 to the adjacent conveying plate 32 below. The magnet block 81 is used to adsorb the adjacent limit steel plate 321 to move in the direction close to the magnet block 81, and the limit steel plate 321 drives the conveying plate 32 to move in the direction close to the magnet block 81. At this time, the pipe on the conveying plate 32 can be separated from the conveying plate 32 and drop onto the slide plate 6. It reduces the situation that the pipe directly drops from a high place and is damaged when the pipe is conveyed by the scraper conveyor 31 to the side close to the conveying mechanism 4, and reduces the falling height of the pipe.

[0072] The reset assembly 9 includes a receiving plate 91 fixedly connected between two mounting plates 311. A driving cylinder 92 is fixedly connected to the receiving plate 91. The piston rod of the driving cylinder 92 is vertically downward and fixedly connected with an arc plate 93, and the middle part of the arc plate 93 gradually bulges downward.

[0073] When the scraper conveyor 31 rotates, the conveying plate 32 close to the arc plate 93 gradually extends downward along the lower surface of the arc plate 93 out of the corresponding conveying rod 316, thus completing the reset of the conveying plate 32. And by starting the driving cylinder 92 to drive the arc plate 93 away from the chain 313, the number of conveying plates 32 that need to be reset can be selected according to needs, the number of pipes conveyed by the scraper conveyor 31 in one rotation can be controlled, and further the conveying rate of the scraper conveyor 31 can be adjusted.

[0074] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
