[0001] The invention relates to the field of metal roller processing, in particular to a convex surface turning device for processing a bamboo pressure roller. Background Art

[0002] In the bamboo processing flow, flattening the bamboo is a critical step. During flattening, a metal convex roller with a certain curvature is usually used to roll the bamboo to shape it. This metal convex roller is turned from a cylindrical roller. By turning the side of the cylindrical roller, a convex surface with a certain curvature is formed.

[0003] However, the existing turning device is not convenient for removing defects on the side of the cylindrical roller, so that the arc convex surface turned out is not smooth enough. It is not convenient to correct the cylindrical roller before turning, which easily causes the cylindrical roller to swing when rotating.

[0007] Furthermore, the rotating mechanism includes a rotating motor, which is fixedly connected to the support frame one, and a ferrule is rotatably connected to the upper part of the support frame one, and the ferrule is connected to the output shaft of the rotating motor, a threaded plate is fixedly connected to one side of the ferrule, and a rotating screw is threadedly connected to the threaded plate, and an extrusion block is rotatably connected to one end of the rotating screw, and the extrusion block contacts the side wall of the ferrule, a bent plate is fixedly connected to one side of the support frame two, and a push-pull frame is slidably connected to the bent plate, an extrusion spring is connected between the push-pull frame and the bent plate, and a roller is rotatably connected to the upper part of the push-pull frame.

[0008] Furthermore, it also includes a correction mechanism, which is arranged on the bottom plate, and is used to correct the position of the cylindrical roller.

[0010] Furthermore, a curved strip is provided at the lower portion of the curved scraper.

[0011] The beneficial effects are as follows: 1. The cylindrical roller is first clamped transversely, and then the side surfaces are subjected to arc turning processes twice in succession, so that the possible defects on the unprocessed side surfaces of the cylindrical roller can be removed first, thereby making the arc surface of the processed pressure roller smoother.

[0012] 2. The rotating rod moves upward and contacts with the rotating shaft of the cylindrical roller. After the two rotating rods contact with the rotating shaft of the cylindrical roller, they will maintain the same lateral state with the cylindrical roller. When the cylindrical roller has a certain inclination angle in the lateral direction, the two rotating rods will also have a certain inclination angle, and due to the gravity of the cylindrical roller itself, the cylindrical roller will only tilt downward toward the side close to the rotating roller, so that the torsion spring is twisted and the pointer deviates from the initial scale on the dial. Then the operator continues to rotate the rotating handle counterclockwise to make the two rotating rods continue to move upward. The rotating rod continues to move upward and will lift up the side of the cylindrical roller close to the rotating roller. Then, as the side of the cylindrical roller close to the rotating roller is slowly lifted up, the pointer will gradually swing in the direction close to the initial scale. When the operator observes that the pointer points to the initial scale on the dial, stop rotating the rotating handle. At this time, the cylindrical roller is in a horizontal state. Then the operator rotates the rotating screw to clamp the cylindrical roller. In this way, the horizontal state of the cylindrical roller is corrected first, and then turning is performed, so that the cylindrical roller is not easy to swing when rotating, thereby making the turning more accurate.

[0013] 3. After the operator places and clamps the cylindrical roller, he releases the push-pull frame to reset it, so that the rotating frame swings downward to drive the support block and the arc scraper to reset downward. The arc scraper will contact the side of the cylindrical roller shaft when it resets downward, and the reset spring is compressed, so that the arc strip at the bottom of the arc scraper is close to the side of the cylindrical roller shaft. Then, when the cylindrical roller is driven by the ferrule to rotate at high speed, the milling cutter head will produce metal debris when turning the cylindrical roller. The arc scraper close to the side of the cylindrical roller shaft will scrape the splashed metal debris from the shaft. In this way, it is not easy for metal debris to be mixed between the cylindrical roller shaft and the two rotating rods, and it is not easy to affect the stability of the cylindrical roller rotation.

A tool holder 53 is fixedly connected between the two limit rods 52. A milling cutter head 54 is fixedly connected to the lower part of the tool holder 53. A sliding frame 55 is slidably connected to the tool holder 53. The sliding frame 55 is made of iron. An inclined top plate 56 is fixedly connected to the heightening frame 1 33. One side of the tool holder 53 contacts the inclined top plate 56. An arc guide frame 1 57 is fixedly connected between one side of the heightening frame 1 33 and the heightening frame 2 34. An arc surface guide frame 2 58 is fixedly connected between the other side of the raising frame 1 33 and the raising frame 2 34, and a convex arc surface and a guide arc surface are respectively provided in the middle of the arc surface guide frame 1 57 and the arc surface guide frame 2 58, and the curvature of the guide arc surface on the arc surface guide frame 2 58 is smaller than the curvature of the convex arc surface on the arc surface guide frame 1 57, and the arc surface guide frame 1 57 and the arc surface guide frame 2 58, one side of the arc surface guide frame 1 57 is fixedly connected with a magnet block 1 59, one side of the arc surface guide frame 2 58 is fixedly connected with a magnet block 2 510, and one side of the sliding frame 55 is in contact with the magnet block 2 510.

[0030] The rotating mechanism includes a rotating motor 61, which is fixedly connected to the support frame 31. A sleeve 62 is rotatably connected to the upper part of the support frame 31. The sleeve 62 is connected to the output shaft of the rotating motor 61. A threaded plate 63 is fixedly connected to one side of the sleeve 62. A rotating screw 64 is threadedly connected to the threaded plate 63. An extrusion block 65 is rotatably connected to one end of the rotating screw 64. The extrusion block 65 contacts the side wall of the sleeve 62. A bent plate 66 is fixedly connected to one side of the support frame 32. A push-pull frame 67 is slidably connected to the bent plate 66. An extrusion spring 68 is connected between the push-pull frame 67 and the bent plate 66. A roller 69 is rotatably connected to the upper part of the push-pull frame 67.

[0031] In actual work, the pressing roller used for flattening bamboo is usually a cylindrical roller with a convex arc surface on the side, which is turned from the side of the cylindrical roller. The operator first pulls the push-pull frame 67 horizontally away from the clamping sleeve 62 to compress the extrusion spring 68, and then puts one end of the rotating axis of the cylindrical roller to be processed horizontally into the clamping sleeve 62. The operator then releases the push-pull frame 67, and the extrusion spring 68 resets and drives the rotating roller 69 to squeeze one end of the cylindrical roller. The operator then rotates the rotating screw 64, and the rotation of the rotating screw 64 will drive the extrusion block 65 to move into the clamping sleeve 62, and then the extrusion block 65 will squeeze one end of the rotating axis of the cylindrical roller, so that the cylindrical roller is clamped. Then the operator starts the rotating motor 61, and the rotating motor 61 will drive the clamping sleeve 6 2 rotates, the sleeve 62 clamps the cylindrical roller, so the sleeve 62 will drive the cylindrical roller to rotate together, and the rotation of the cylindrical roller will also drive the roller 69 clamping the other end of the cylindrical roller to rotate together through friction. After the cylindrical roller rotates stably, the operator starts the electric slider 51 again, and the electric slider 51 drives the tool holder 53 and the sliding frame 55 to move horizontally in the direction away from the rotating motor 61. At first, one side of the sliding frame 55 contacts with the magnet block 2 510 and is attracted by the magnet block 2 510, and one side of the sliding frame 55 contacts with the arc guide frame 2 58, and then the sliding frame 55 will be out of contact with the magnet block 2 510 before the magnet block 2 510 when moving horizontally. Then, after the sliding frame 55 moves horizontally for a distance, the milling cutter head 54 begins to contact with the side of the cylindrical roller, and at the same time, the sliding frame The side of the sliding frame 55 close to the arc surface guide frame 2 58 will move horizontally along the arc surface on the arc surface guide frame 2 58, so that the sliding frame 55 will be guided by the arc surface guide frame 2 58 when it moves horizontally in the direction away from the rotating motor 61, and the sliding frame 55 guided by the arc surface guide frame 2 58 will drive the milling head 54 to initially turn the side of the cylindrical roller, so that a convex arc surface is initially formed on the side of the cylindrical roller. When the milling head 54 completes one turning of the side of the cylindrical roller, the electric slider 51 stops moving, and the sliding frame 55 moves horizontally to the magnet block 1 59, and then the magnet block 1 59 attracts one side of the sliding frame 55, so that the sliding frame 55 moves horizontally for a distance in the direction close to the magnet block 1 59 and is sucked by the magnet block 1 59, so that one side of the sliding frame 55 One side is out of contact with the arc surface guide frame 2 58 and the other side is in contact with the arc surface guide frame 1 57, then the electric slider 51 is horizontally moved and reset in the direction close to the rotating motor 61, driving the sliding frame 55 to horizontally move and reset along the arc surface guide frame 1 57 in the direction close to the rotating motor 61, and then the sliding frame 55 is guided by the arc surface guide frame 1 57 when moving horizontally in the direction close to the rotating motor 61, and the sliding frame 55 guided by the arc surface guide frame 1 57 will drive the milling cutter head 54 to further turn the side surface of the cylindrical roller, so that the side surface of the cylindrical roller further forms a convex arc surface, completing the turning of the cylindrical roller, and then the tool holder 53 will squeeze the inclined top plate 56 at the end of horizontally moving and resetting together with the electric slider 51, driving the sliding frame 55 to move upward for a distance,The sliding frame 55 is disengaged from the arc surface guide frame 1 57, and moves upward for a distance to be attracted by the magnet block 2 510, so that one side of the sliding frame 55 contacts the magnet block 2 510 and the arc surface guide frame 2 58, and the reset is completed. The cylindrical roller is first clamped horizontally, and then the side surface is subjected to arc surface turning twice in succession, so that the defects that may exist on the side surface of the unprocessed cylindrical roller can be removed first, so that the arc surface of the processed pressure roller is smoother.

[0032] Example 2

[0033] On the basis of Example 1, Figure 7-8 As shown, a correction mechanism is also included, which is arranged on the base plate 2. The correction mechanism is used to correct the position of the cylindrical roller. The correction mechanism includes a vertical rod 71, which is fixedly connected to the side of the base plate 2 close to the support frame 2 32. A rotating handle 72 is rotatably connected to the vertical rod 71, and a worm 73 is fixedly connected to one side of the rotating handle 72. A straight rod frame 74 is fixedly connected to the base plate 2, and a worm gear 75 is rotatably connected to the straight rod frame 74. The worm gear 75 is meshed with the worm 73. A limited position frame 76 is fixedly connected to the base plate 2, and a square rod frame 77 is placed on the base plate 2. The lower part of the frame 77 passes through the limit frame 76, and a spur rack 78 is fixedly connected to one side of the square rod frame 77, and the spur rack 78 is meshed with the worm gear 75. The upper part of the square rod frame 77 is rotatably connected to a swing frame 79, and a torsion spring 710 is connected between the swing frame 79 and the square rod frame 77. Two rotating rods 711 are rotatably connected to the swing frame 79, and a pointer 712 is fixedly connected to one side of the swing frame 79. A dial 713 is fixedly connected to one side of the square rod frame 77, and an indicating scale is provided on the dial 713. The lower part of the pointer 712 is in contact with the dial 713, and the lower end of the pointer 712 points to the initial scale.

[0034] After the operator places one end of the cylindrical roller in the sleeve 62 and the other end of the cylindrical roller is squeezed by the rotating roller 69, the operator first rotates the rotating handle 72 counterclockwise. The counterclockwise rotation of the rotating handle 72 will drive the worm 73 to rotate together. The counterclockwise rotation of the worm 73 will drive the spur rack 78 to move slowly upward through the worm gear 75. The upward movement of the spur rack 78 will drive the straight rod frame 74 to move upward. The upward movement of the straight rod frame 74 will drive the swing frame 79 and the rotating rod 711 to move slowly upward together. The rotating rod 711 moves upward and contacts with the rotating shaft of the cylindrical roller. After the two rotating rods 711 contact the rotating shaft of the cylindrical roller, they will maintain the same lateral state with the cylindrical roller. When the cylindrical roller has a certain inclination angle laterally, the two rotating rods 711 will also have a certain inclination angle, and due to the gravity of the cylindrical roller itself, the cylindrical roller will only move closer to One side of the roller 69 is tilted downward, so that the torsion spring 710 is twisted and the pointer 712 deviates from the initial scale on the dial 713. The operator then continues to rotate the rotating handle 72 counterclockwise, so that the two rotating rods 711 continue to move upward. The continued upward movement of the rotating rod 711 will lift up the side of the cylindrical roller close to the roller 69. Then, as the side of the cylindrical roller close to the roller 69 is slowly lifted up, the pointer 712 will gradually swing in the direction close to the initial scale. When the operator observes that the pointer 712 points to the initial scale on the dial 713, the rotating handle 72 is stopped. At this time, the cylindrical roller is in a horizontal state. The operator then rotates the rotating screw 64 to clamp the cylindrical roller. In this way, the horizontal state of the cylindrical roller is corrected first, and then turning is performed, so that the cylindrical roller is not easy to swing when rotating, thereby making the turning more accurate.

[0035] Example 3

[0036] On the basis of Example 2, Figure 9-11 As shown, it also includes a scraping mechanism, which is arranged on the elevated frame 34, and is used to keep the cylindrical roller shaft in a clean state. The scraping mechanism includes a rotating frame 81, and the rotating frame 81 is rotatably connected to the elevated frame 34. Two gears 82 are fixedly connected to the rotating frame 81. A rack bent rod 83 is fixedly connected to the upper part of the push-pull frame 67, and the rack bent rod 83 is meshed with the two gears 82. One end of the rotating frame 81 is rotatably connected to a support block 84, and a curved scraper 85 is slidably connected to the lower part of the support block 84. A return spring 86 is connected between the curved scraper 85 and the support block 84.

[0037] The arc scraper 85 has an arc strip at its lower portion.

[0038] Before placing the cylindrical roller, the operator must first open the push-pull frame 67. When the push-pull frame 67 is horizontally pulled away from the rotating motor 61, it will drive the rack bent rod 83 to move horizontally. The rack bent rod 83 moves horizontally away from the rotating motor 61, which will drive the gear 82 to rotate. The rotation of the gear 82 will drive the rotating frame 81 to swing upward by a certain angle. The upward swing of the rotating frame 81 will lift the support block 84 and the curved scraper 85 upward, which makes it easier to place the cylindrical roller. After the operator places and clamps the cylindrical roller, he releases the push-pull frame 67 to reset it, so that the rotating frame 81 swings downward The support block 84 and the arc scraper 85 are driven to reset downward. The arc scraper 85 will contact the side of the cylindrical roller shaft when it resets downward, and the reset spring 86 is compressed, so that the arc strip at the bottom of the arc scraper 85 is in close contact with the side of the cylindrical roller shaft. Then, when the cylindrical roller is driven by the sleeve 62 to rotate at high speed, the milling head 54 will produce metal debris when turning the cylindrical roller. The arc scraper 85 close to the side of the cylindrical roller shaft will scrape the splashed metal debris from the shaft. In this way, it is not easy for metal debris to be mixed between the cylindrical roller shaft and the two rotating rods 711, and it is not easy to affect the stability of the rotation of the cylindrical roller.
