Description

Technical Field

[0001] This invention belongs to the field of pipe fitting processing technology, specifically a greenhouse pipe fitting processing and cutting device. Background Technology

[0002] The pipes used in greenhouses are usually metal, such as galvanized steel pipes or plastic pipes, and may have different diameters and thicknesses. During the processing of greenhouse pipe fittings, these long pipes usually need to be cut to a certain length to facilitate subsequent installation and use. Cutting greenhouse pipe fittings is usually done using a slitting device.

[0003] Chinese patent CN213766093U discloses a pipe cutting device for easy transport, comprising a base plate, a conveyor belt, pipe clamps, and cutting blades. The conveyor belt is positioned above the base plate, and the pipe clamps are positioned above the conveyor belt. A cutting body is positioned on the upper side of the base plate, and a hydraulic cylinder is installed inside the cutting body. A hydraulic rod is positioned below the hydraulic cylinder, and a blade holder is positioned below the hydraulic rod. A cutting blade is positioned below the blade holder, and a chain is installed below the cutting blade. A support frame is installed inside the chain, and a connecting rod is positioned below the support frame. A sliding barrel is connected below the connecting rod, and a spring is installed inside the sliding barrel. A limit buckle is installed on the inner side of the support frame, and a connecting block is positioned at the bottom of the chain. This pipe cutting device for easy transport can automatically transport pipes, effectively fix pipes, has a fast cutting speed, and is highly practical.

[0004] In current technology, cutting pipes with a cutting blade will produce burrs at the cut. If the burrs are not polished, they will cause the pipe insertion gap to exceed the tolerance, and the burrs will cause the board to get stuck, making it difficult to put the board into place, which will affect the construction of the greenhouse. Moreover, pests prefer to lay eggs in the burr gaps, leading to the growth of bacteria.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] In existing technologies, cutting pipe fittings with a cutting blade will produce burrs at the cut. If the burrs are not polished, they will cause the pipe insertion gap to exceed the tolerance, and the burrs will cause the board to be difficult to position, affecting the construction of the greenhouse. Moreover, pests prefer to lay eggs in the burr gaps, leading to the growth of bacteria.

[0024] Based on this, such as Figures 1 to 5As shown, this embodiment of the invention provides a greenhouse pipe fitting processing and cutting device, including a roller conveyor 1; one end of the roller conveyor 1 is provided with a pushing mechanism for pushing out the cut pipes; a guide plate 3 is fixedly connected to the side wall of the roller conveyor 1, and a rotating plate 32 is rotatably connected to the end of the guide plate 3 away from the roller conveyor 1 via a rotating shaft for blocking the slipping pipes; a driving mechanism is provided on one side of the rotating plate 32; a grinding mechanism is provided on both sides of the guide plate 3; the grinding mechanism includes a base 33 fixedly connected to the bottom of the guide plate 3, guide rails 351 are fixedly connected to the top of both ends of the base 33, sliding frames 331 are slidably connected to the guide rails 351, a first motor 332 is fixedly connected to the side wall of the sliding frame 331, and a grinding wheel 333 is fixedly connected to the output shaft of the first motor 332; two third cylinders 35 are fixedly connected to the top of the base 33, and the output ends of the third cylinders 35 are respectively fixedly connected to adjacent sliding frames 331.

[0025] In use, the grinding mechanism provided in this embodiment of the invention feeds the pipe onto the roller conveyor 1 via a feeding conveyor frame. During the pipe conveying process, the roller conveyor 1 requires fixed limiting to improve the stability and accuracy of the cutting. After slitting, the next pipe is conveyed, pushing the already cut pipe to the pushing mechanism. The pushing mechanism then pushes the pipe down until it falls onto the guide plate 3. The guide plate 3 is inclined, and the slid-out pipe slides to the position of the rotating plate 32, which is perpendicular to the guide plate 3. The pipe is blocked, and then the third cylinder 35 is activated. The output end of the third cylinder 35 drives the sliding frame 331 to move. The sliding frame 331 slides stably on the guide rail 351 and drives the first motor 332 and the grinding wheel 333 to move until the pipe is limited between the two grinding wheels 333. Then, the first pressing block 342 at the top presses the pipe downwards, and then the first motor 332 is activated. The first motor 332 drives the grinding wheel 333 to rotate, thereby cleaning the burrs at the cut of the pipe and realizing the function of quickly cleaning burrs.

[0026] like Figure 5 As shown, cleaning blocks 352 are fixedly connected to the side wall of the sliding frame 331 near the third cylinder 35, and the cleaning blocks 352 are all sleeved on the outside of the guide rail 351; the top of both ends of the base 33 are provided with a material drop port 353, and the side wall of the base 33 is provided with a material outlet 354, the top of the material outlet 354 is connected to the material drop port 353.

[0027] When the cleaning block 352 provided in this embodiment of the invention is in use, the sliding frame 331 moves during the movement of the sliding frame 331, and the cleaning block 352 moves during the movement of the cleaning block 352, pushing the grinding debris above the base 33. During the pushing process, the debris falls from the discharge port 353 and then slides in the discharge port 354, preventing it from accumulating on the guide rail 351 and affecting the sliding of the sliding frame 331.

[0028] like Figure 3 and Figure 4 As shown, the driving mechanism includes a first rotating wheel 322 fixedly connected to one end of a rotating shaft; a mounting plate 3211 fixedly connected to the bottom of the guide plate 3; a second rotating wheel 324 rotatably connected to the side wall of the mounting plate 3211 via a pin; a belt 323 is sleeved between the second rotating wheel 324 and the first rotating wheel 322; a gear 325 fixedly connected to the outer wall of the pin; and an electric push rod 327 fixedly connected to the bottom of the guide plate 3. The output of the electric push rod 327... A rack 326 is fixedly connected to the end via a connecting plate 328, and the rack 326 meshes with a gear 325; a limit rod 329 is fixedly connected to the bottom of the guide plate 3, and the connecting plate 328 is slidably connected to the limit rod 329; a baffle 3210 is fixedly connected to the bottom of the guide plate 3 near the outer side of the electric push rod 327; a protective shell 321 is provided on the outer side of the first rotating wheel 322 and the second rotating wheel 324, and the protective shell 321 is fixedly connected to the side wall of the guide plate 3.

[0029] When the drive mechanism provided in this embodiment of the invention needs to block the pipe for grinding, the rotating plate 32 rotates upward. After grinding, the rotating plate 32 needs to rotate downward to facilitate the pipe sliding to the next process. By activating the electric push rod 327, the output end of the electric push rod 327 drives the connecting plate 328 to move. The connecting plate 328 drives the rack 326 to move. The rack 326 drives the gear 325 to rotate. The gear 325 drives the pin shaft to rotate. The pin shaft drives the second rotating wheel 324 to rotate. The second rotating wheel 324 drives the belt 323 to rotate. The belt 323 drives the first rotating wheel 322 to rotate. The first rotating wheel 322 drives the rotating shaft to rotate. The rotating shaft drives the rotating plate 32 to rotate, thereby facilitating the blocking and diversion of the pipe. In another embodiment, another driving method is also provided to realize the flipping of the pipe.

[0030] In another embodiment, such as Figure 11As shown, a limiting component is provided at the end of the rotating shaft away from the first rotating wheel 322. Specifically, the limiting component includes a ratchet 362 fixedly connected to one end of the rotating shaft. A pawl 363 is rotatably connected to the side wall of the guide plate 3 near the ratchet 362 via a pin. The pawl 363 meshes with the ratchet 362. A tension spring 364 is provided between the pawl 363 and the guide plate. A rocker arm 36 is fixedly connected to one end of the rotating shaft. A counterweight 361 is fixedly connected to the end of the rocker arm 36 away from the ratchet 362. A trigger rod 36 is fixedly connected to the top of both ends of the base 33. In normal operation, the counterweight 361 and the rotating plate 32 form a torque balance, maintaining a vertical blocking state and keeping the rotating plate 32 vertical to block the pipe. Trigger rods 36 are installed at both ends of the top of the base 33. When grinding is complete and the third cylinder 35 retracts, the sliding frame 331 strikes the trigger rod 36. The trigger rod 36 transmits this electrical signal to the control system, which releases a pawl 363, releasing it from the ratchet 362. The torque balance is broken, thereby unlocking the rotating plate 32. At this time, the weight of the pipe overcomes the torque of the counterweight 361, pressing the rotating plate 32 downward to achieve release. After the pipe slips, the counterweight 361 pulls the rotating plate 32 to reset, and the pawl 363 locks the rotating plate 32 again under the action of the tension spring 364. If the counterweight 361 is too heavy, the pipe will not be able to trigger the rotation. If it is too light, it may cause accidental rotation. Therefore, an adjustable counterweight design is required, and it is adjusted on-site to the critical balance point.

[0031] In practical applications, the two drive methods can be used individually or in combination. The drive method using counterweight 361 and trigger rod 36 utilizes the tube's own weight to achieve rotation, which is energy-efficient and effective. Pad 363 automatically locks to prevent the plate from falling accidentally. The simple structure is suitable for harsh industrial environments. The drive method using gear 325 and rack 326 is suitable for automated production lines that require precise synchronization, and both methods can achieve the rotation effect of rotating plate 32. The locking mechanism composed of ratchet 362 and pad 363 is applicable to both drive methods. When locking gear 325 and rack 326, when the rotating plate 32 is rotated to a vertical position by gear 325, pad 363 is inserted into ratchet 362 under the action of tension spring 364, locking the shaft and fixing the rotating plate 32. This prevents the tube from falling accidentally in the event of a power outage, which could damage the tube and the structure on the base 33.

[0032] On the one hand, it can be used alone to control the rotating plate 32; on the other hand, if the counterweight 361 and trigger rod 365 are not used, the ratchet 362 and pawl 363 form a locking structure, which makes it easy to lock the rotating plate 32 under the action of the drive mechanism.

[0033] like Figure 5As shown, a support frame 34 is fixedly connected to the top of one of the sliding frames 331, and a second cylinder 341 is fixedly connected to the top of the support frame 34. The output end of the second cylinder 341 passes through the support frame 34 and is fixedly connected to a first pressing block 342.

[0034] The first pressing block 342 provided in this embodiment of the invention is used to fix the cut pipe. By opening the second cylinder 341, the output end of the second cylinder 341 drives the first pressing block 342 to move. The first pressing block 342 moves downward to the upper surface of the pipe to fix the pipe, which is convenient for grinding.

[0035] like Figure 2 As shown, the top of the guide plate 3 near the roller conveyor 1 is fixed with two first fixing plates 311. Two slide rods 312 are slidably connected to each of the first fixing plates 311. One end of each slide rod 312 is fixed with a limit plate 31. A spring 313 is sleeved on the outside of each slide rod 312. The two ends of the spring 313 are fixed to the first fixing plate 311 and the limit plate 31, respectively.

[0036] The limiting plate 31 provided in this embodiment of the invention is used to limit the pipe material during use. The pushing mechanism pushes the pipe material from the roller conveyor 1 onto the guide plate 3. During the movement, both ends of the pipe material contact the limiting plate 31. Under the action of the spring 313, the pipe material is initially centered adaptively, so that the pipe material slides down as close to the middle of the guide plate 3 as possible, while absorbing part of the gravitational potential energy and reducing the impact on the rotating plate 32.

[0037] like Figure 6 As shown, the pushing mechanism includes a fixed frame 21 fixed to the bottom of the roller conveyor 1. A first cylinder 22 is fixed to the bottom of the fixed frame 21. A trapezoidal frame 2 is fixed to the output end of the first cylinder 22. Two vertical rods 23 are fixed to the bottom of the trapezoidal frame 2. The vertical rods 23 are slidably connected to the fixed frame 21.

[0038] The pushing mechanism provided in this embodiment of the invention is used to push the pipe from the roller conveyor 1 onto the guide plate 3. When pushing is required, the first cylinder 22 is turned on, and the output end of the first cylinder 22 drives the trapezoidal frame 2 to move. The pipe slides down the trapezoidal frame 2 onto the guide plate 3.

[0039] like Figure 7 and Figure 9As shown, the bottom of the roller conveyor 1 is fixedly connected to two second fixed plates 52. A bidirectional lead screw 54 is rotatably connected between the two second fixed plates 52 via bearings. Two moving blocks 51 are threaded onto the bidirectional lead screw 54. Each moving block 51 is rotatably connected to a limit roller 5. Two guide rods 55 are fixedly connected between the two second fixed plates 52. The moving blocks 51 are slidably connected to the two guide rods 55. A third motor 53 is fixedly connected to the side wall of the second fixed plate 52. The output shaft of the third motor 53 is fixedly connected to the bidirectional lead screw 54.

[0040] The limiting roller 5 provided in this embodiment of the invention is used to limit the movement of the pipe. By turning on the third motor 53, the output shaft of the third motor 53 drives the bidirectional lead screw 54 to rotate, which in turn drives the moving block 51 to move. The moving block 51 then drives the limiting roller 5 to move until it reaches both sides of the pipe, thereby limiting the movement of the pipe. This facilitates the transport of the pipe in the middle of the roller conveyor 1 and makes it easier to cut. During the movement, the moving block 51 slides on the guide rod 55, which limits the movement of the moving block 51 in the horizontal direction.

[0041] like Figure 7 and Figure 8 As shown, a cutting frame 4 is fixedly connected to the top of the roller conveyor 1, a fourth cylinder 41 is fixedly connected to the top of the cutting frame 4, a protective cover 42 is fixedly connected to the output end of the fourth cylinder 41, a cutting wheel 43 is rotatably connected to the inner wall of the protective cover 42 via a cutter shaft, a second motor 44 is fixedly connected to the side wall of the protective cover 42, and the output shaft of the second motor 44 is fixedly connected to one end of the cutter shaft; a cutting seat 45 is fixedly connected to the roller conveyor 1, the cutting seat 45 is located directly below the cutting wheel 43 and cooperates with the cutting wheel 43.

[0042] The cutting wheel 43 and cutting seat 45 provided in this embodiment of the invention are used to cut pipes. After the pipe moves to the set position, it is fixed. By opening the fourth cylinder 41, the output end of the fourth cylinder 41 drives the protective cover 42 to move. The protective cover 42 drives the cutting wheel 43 to move downward until the pipe is cut. The cutting seat 45 is located directly below the cutting wheel 43 to facilitate support at the pipe cutting point. When the cutting wheel 43 cuts to the bottom, it will be inserted into the cutting seat 45.

[0043] like Figure 10As shown, two third fixing plates 62 are fixedly connected to the side wall of the cutting frame 4. A reciprocating screw 64 is rotatably connected between the two third fixing plates 62 via bearings. A lifting frame 6 is threaded onto the reciprocating screw 64. A second pressing block 61 is fixedly connected to the bottom of both ends of the lifting frame 6. Two sliding rods 65 are fixedly connected between the two third fixing plates 62. The lifting frame 6 is slidably connected to the sliding rods 65. A fourth motor 63 is fixedly connected to the top of the third fixing plate 62. The output shaft of the fourth motor 63 is fixedly connected to one end of the reciprocating screw 64.

[0044] The second pressing block 61 provided in this embodiment of the invention is used to fix the pipe to be cut. By turning on the fourth motor 63, the output shaft of the fourth motor 63 drives the reciprocating screw 64 to rotate, which in turn drives the lifting frame 6 to move. The lifting frame 6 then drives the second pressing block 61 to move until the second pressing block 61 presses against the top of the pipe to prevent it from shaking during cutting and causing an uneven cut. During the movement, the lifting frame 6 slides on the sliding rod 65, which limits the movement of the lifting frame 6 in the vertical direction.

[0045] like Figure 8 As shown, a photoelectric sensor 46 is fixedly connected to the side wall of the cutting frame 4 near the trapezoidal frame 2, and a displacement sensor 47 is also installed at the bottom of the photoelectric sensor 46.

[0046] When the photoelectric sensor 46 and displacement sensor 47 provided in this embodiment of the invention are in use, when the pipe moves to the photoelectric sensor 46, the photoelectric sensor 46 transmits a signal to the control system, and the control system controls the displacement sensor 47 to turn on. The displacement sensor 47 is used to monitor the displacement of the pipe during transportation. When the pipe is displaced to a set value, the displacement sensor 47 transmits a signal to the control system, and the control system controls the roller conveyor 1 to stop transportation and the fourth motor 63 to turn on to press the pipe, and then the cutting operation can be performed.

[0047] Working principle: When the pipe moves to the photoelectric sensor 46, the photoelectric sensor 46 transmits a signal to the control system, which then controls the displacement sensor 47 to turn on. The displacement sensor 47 is used to monitor the displacement of the pipe during transportation. When the pipe is displaced to the set value, the displacement sensor 47 transmits a signal to the control system, which then controls the roller conveyor 1 to stop transporting and the fourth motor 63 to turn on. The output shaft of the fourth motor 63 drives the reciprocating screw 64 to rotate, which in turn drives the lifting frame 6 to move. The lifting frame 6 then drives the second pressing block 61 to move until the second pressing block 61 presses against the top of the pipe to prevent it from shaking during cutting and causing an uneven cut. During the movement of the lifting frame 6, the lifting frame 6 slides on the sliding rod 65, which limits the movement of the lifting frame 6 in the vertical direction.

[0048] After the pipe moves to the set position, it is fixed. By opening the fourth cylinder 41, the output end of the fourth cylinder 41 drives the protective cover 42 to move. The protective cover 42 drives the cutting wheel 43 to move downward until the pipe is cut. The cutting seat 45 is located directly below the cutting wheel 43 to facilitate support at the pipe cutting point. When the cutting wheel 43 cuts to the bottom, it will be inserted into the cutting seat 45.

[0049] When pushing is required, the first cylinder 22 is activated, and its output end drives the trapezoidal frame 2 to move, causing the pipe to slide down onto the guide plate 3. The pushing mechanism pushes the pipe from the roller conveyor 1 onto the guide plate 3. During this movement, both ends of the pipe contact the limiting plate 31. Under the action of the spring 313, the pipe is initially centered, allowing it to slide as close to the center of the guide plate 3 as possible, while absorbing some of the gravitational potential energy and reducing impact on the rotating plate 32. The second cylinder 341 is activated, and its output end drives the first pressing block 342 to move downwards to the upper surface of the pipe, fixing it for easy grinding.

[0050] The pipes are fed onto the roller conveyor 1 via a feeding conveyor frame. During the pipe conveying process, the roller conveyor 1 needs to be fixed and limited to improve the stability and accuracy of the cutting. After the pipes are cut, the next pipe is pushed to the pushing mechanism during the conveying process. The pushing mechanism then pushes the pipes down until they fall onto the guide plate 3. The guide plate 3 is tilted, and the cut pipes will slide to the position of the rotating plate 32. The rotating plate 32 is perpendicular to the guide plate 3 and blocks the pipes. Then, the third cylinder 35 is activated, and the output end of the third cylinder 35 drives the sliding frame 331 to move. The sliding frame 331 slides stably on the guide rail 351 and drives the first motor 332 and the grinding wheel 333 to move until the pipe is limited between the two grinding wheels 333. Then, the first pressing block 342 at the top presses the pipe downwards, and then the first motor 332 is activated. The first motor 332 drives the grinding wheel 333 to rotate, thereby cleaning the burrs at the cut of the pipe and realizing the function of quickly cleaning burrs.

[0051] When it is necessary to block the pipe for grinding, the rotating plate 32 rotates upward. After grinding, the rotating plate 32 needs to rotate downward to facilitate the pipe sliding to the next process. By activating the electric push rod 327, the output end of the electric push rod 327 drives the connecting plate 328 to move. The connecting plate 328 drives the rack 326 to move. The rack 326 drives the gear 325 to rotate. The gear 325 drives the pin to rotate. The pin drives the second rotating wheel 324 to rotate. The second rotating wheel 324 drives the belt 323 to rotate. The belt 323 drives the first rotating wheel 322 to rotate. The first rotating wheel 322 drives the rotating shaft to rotate. The rotating shaft drives the rotating plate 32 to rotate, thereby facilitating the blocking and diversion of the pipe.
