Description

Technical Field

[0001] The invention belongs to the technical field of conveying equipment, and in particular relates to a roller structure for conveying brittle objects. Background Art

[0002] Brittle objects refer to materials or items that tend to break or shatter rather than deform when subjected to force. Such materials tend to break directly without significant plastic deformation under external force. Common brittle materials include ceramics, glass, cast iron, and certain types of plastics and alloys. In the process of conveying plate-like brittle objects, conveyor roller structures are often used to complete the conveying.

[0003] When using a roller structure to convey brittle objects, in order to prevent the brittle objects from slipping or being worn and damaged, a roller with a softer texture is used for conveying, or a roller with a rubber sleeve on the outer wall is used for conveying. However, it is found during use that when the weight of the brittle object is heavy, the flexible roller will deform slightly when subjected to force, that is, the roller will be flattened, so the support height of the current roller will be slightly lower than the height of the unsupported roller. When the brittle object moves to the next undeformed roller, the edge of the brittle component will have a certain angle with the edge of the roller, rather than being tangent. Therefore, the brittle object will generate an impact force with the roller. This impact force will increase with the increase of the speed of the brittle object, which can easily cause damage to the brittle object and the roller itself. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a roller structure for conveying brittle objects that can overcome the above problems or at least partially solve the above problems.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] A roller structure for conveying brittle objects comprises a frame body, and also comprises: a plurality of support plates arranged at equal intervals, fixedly connected to the bottom of the frame body, wherein a plurality of the support plates are rotatably connected to a rotating shaft, both ends of a plurality of the rotating shafts are fixedly connected to an inclined plate, the other end of each pair of the inclined plates is rotatably mounted with a roller shaft via a rotating rod, the frame body is provided with a driving source for driving the plurality of roller shafts to rotate; a pressing component is arranged on the support plate, and when one of the roller shafts is pressed downward, the pressing component drives the next roller shaft to be pressed downward to swing downward and reset.

[0007] Preferably, the driving source includes a short shaft rotatably mounted on the inclined plate, the axis of the short shaft is colinearly arranged with the axis of the rotating shaft, the short shaft is connected to the rotating rod via a belt drive, and a driving motor for driving the short shaft to rotate is fixedly mounted on the frame.

[0008] Further, driving gears are fixedly connected to multiple short axes, and a plurality of transmission gears are rotatably installed on the outer wall of the frame body. The plurality of transmission gears are respectively located between two adjacent driving gears and are meshed with the driving gears.

[0009] Preferably, the pressing member includes a reciprocating lead screw rotatably connected to the frame body. A reciprocating slider slidably connected to the frame body is installed on the reciprocating lead screw. A first rack is fixedly connected to the reciprocating slider. A driven gear meshed with the first rack is fixedly installed on the outer wall of the rotating shaft. A driven gear is installed at the shaft end of the reciprocating lead screw through a one-way bearing. A linkage member for driving the driven gear to rotate is provided on the frame body.

[0010] Further, the linkage member includes a cylinder fixedly connected to the frame body. A piston block is slidably installed in the cylinder. A first spring is installed between the piston block and the inner top of the cylinder. A second rack meshed with the driven gear is fixedly connected to the lower end of the piston block. Fine holes and thick holes are respectively provided at the upper and lower ends of the cylinder. A blowing portion for blowing air to the inner top of the cylinder is provided on the roller shaft.

[0011] Furthermore, the blowing portion includes inner holes provided in the roller shaft. The plurality of inner holes are close to the circumferential outer wall of the roller shaft. Annular covers are fixedly connected to both inclined plates. The open ends of the two annular covers are respectively rotatably connected to both ends of the roller shaft. The two ends of the inner hole are respectively communicated with the two annular covers. An air suction pipe and an exhaust pipe are respectively fixedly connected to the two annular covers. Check valves are fixedly installed in both the air suction pipe and the exhaust pipe. The end of the exhaust pipe extends to the inner top of the cylinder of the roller shaft at an adjacent position.

[0012] Furthermore, a collection box is fixedly connected to the bottom of the frame body. A slot facing the bottom of the roller shaft is provided at the top of the collection box. A filter plate is installed in the collection box. The suction end of the air suction pipe extends to the inner bottom of the collection box. A brush plate is installed in the upper port of the collection box. When the roller shaft swings downward, the brush plate will abut against the outer wall of the roller shaft.

[0013] Preferably, a plurality of cross bars are fixedly connected to the frame body. Slide tables are slidably installed at both ends of each cross bar. A longitudinal roller is rotatably installed at the lower end of each slide table. The longitudinal roller is located in the gap between two adjacent roller shafts. An opening and closing portion for driving the slide tables on both sides to open and close is provided on the frame body.

[0014] Further, the opening and closing part includes a double-headed threaded rod rotatably connected to the frame body. The two side sliding tables are respectively threadedly connected to the two ends of the double-headed threaded rod. A driving gear is fixedly installed at the shaft end of the double-headed threaded rod, and an arc-shaped rack meshed with the driving gear is fixedly connected to the inclined plate.

[0015] Further, a horizontal pipe is fixedly connected to the top of the frame body. A spray head facing the outer wall of the roller shaft is fixedly installed on the outer wall of the horizontal pipe. The exhaust ends of the fine holes and the thick holes are connected to the horizontal pipe through connecting pipes.

[0016] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0017] 1. After the inclined plate drives the roller shaft to swing downward and then swing upward to reset in the present invention, when the brittle object contacts the next roller shaft, the next roller shaft will swing downward in advance, which can reduce the impact force between the brittle object and the roller shaft, and even there will be no impact, so that the brittle object and the roller shaft are not easily damaged, and the process of conveying the brittle object will be more stable.

[0018] 2. In the present invention, the continuously rotating roller shaft will continuously suck and discharge air in the inner hole, so that the roller shaft can be effectively cooled, preventing the roller shaft with repeated deformation from overheating and improving the anti-slip performance, indirectly extending the service life of the roller shaft.

[0019] 3. In the present invention, the collecting box is sucked air through the suction pipe, and the collecting box will suck air from the outer wall of the roller shaft through the slot. On the one hand, it can suck part of the dust on the outer wall of the roller shaft and filter it through the filter plate. On the other hand, it can cool the outer wall of the roller shaft, so that the roller shaft maintains good heat dissipation performance and anti-slip performance.

[0020] 4. When the roller shaft swings downward and obliquely in the present invention, the roller shaft will also top against the brush plate, and the rotating roller shaft will be cleaned by the brush plate, which can further improve the effect of cleaning the outer wall of the roller shaft. When the roller shaft swings upward and resets, the brush plate will separate from the roller shaft. On the one hand, it prevents the brush plate from wearing the roller shaft after long-term contact with the roller shaft. On the other hand, after the brush plate is separated from the roller shaft, the continuously sucking slot can suck the floating dust on the brush plate, ensuring the continuous cleaning ability of the brush plate.

Detailed implementation manners

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0034] Embodiment 1: Refer to Figures 1-9 , a roller structure for conveying brittle objects, including a frame 1 for supporting the entire device, and further including: a plurality of equally spaced support plates 2 fixedly connected to the bottom of the frame 1. Among them, a rotating shaft 3 is rotatably connected to each of the multiple support plates 2. Both ends of the multiple rotating shafts 3 are fixedly connected with inclined plates 4 arranged obliquely. The other end of each pair of inclined plates 4 is rotatably installed with a roller shaft 6 through a rotating rod 5. The roller shaft 6 is fixedly connected to the rotating rod 5. A driving source for driving the multiple roller shafts 6 to rotate is provided on the frame 1; a pressing component is arranged on the support plate 2. When one of the roller shafts 6 is pressed downward, the pressing component will drive the next roller shaft 6 to be pressed downward to swing downward and then reset.

[0035] Specifically, during use, the driving source can drive the rotating rod 5 to rotate, and the rotating rod 5 can drive the roller shaft 6 to rotate. The multiple equally spaced roller shafts 6 can then achieve the conveying work of the brittle objects. When the brittle objects are conveyed on the roller shafts 6, the weight of the brittle objects will squeeze the roller shafts 6, flattening the surface of the roller shafts 6 in contact with the brittle objects. Then, the pressing component will drive the inclined plate 4 to swing downward and then swing upward to reset, and drive the roller shaft 6 to swing downward and then swing upward to reset. Thus, when the brittle objects come into contact with the next roller shaft 6, the next roller shaft 6 will swing downward in advance, reducing the impact force between the brittle objects and the roller shafts 6, and even preventing impacts. In this way, the brittle objects and the roller shafts 6 are not easily damaged, and the process of conveying the brittle objects will also be smoother.

[0036] In practice, the height difference of the up-and-down swing of the roller shaft 6 is between 1 mm and 5 mm.

[0037] A top cover 41 is fixedly connected to the top of the above-mentioned frame 1, and a dust suction pipe 10 is fixedly connected to the top cover 41. A dust suction device for sucking floating dust is fixedly installed in the dust suction pipe 10, so that the floating dust generated during the conveying process can be sucked and the roller shaft 6 can be cooled.

[0038] Embodiment 2: Refer to Figures 1-2 and Figures 4-6 , a roller structure for conveying brittle objects, which is basically the same as Embodiment 1. Further:

[0039] The above driving source includes a short shaft 12 rotatably mounted on the inclined plate 4. The axis of the short shaft 12 is collinear with the axis of the rotating shaft 3. The short shaft 12 is connected to the rotating rod 5 through a belt drive 11. The belt drive 11 mainly consists of two belt pulleys and a belt used in cooperation with the belt pulleys. A driving motor 7 for driving the short shaft 12 to rotate is fixedly installed on the frame 1.

[0040] Specifically, during use, the driving motor 7 is started. The driving motor 7 can drive the short shaft 12 to rotate, and the short shaft 12 can drive the rotating rod 5 to rotate through the belt drive 11. The rotating rod 5 can then drive the roller shaft 6 to rotate. Multiple roller shafts 6 arranged at equal intervals can thus achieve the conveying work of brittle objects.

[0041] What is different from the above is that: driving gears 8 are fixedly connected to multiple short shafts 12. A plurality of transmission gears 9 are rotatably installed on the outer wall of the frame 1. The plurality of transmission gears 9 are respectively located between two adjacent driving gears 8 and are meshed with the driving gears 8.

[0042] Specifically, when one of the short shafts 12 rotates, the short shaft 12 will drive all the short shafts 12 to rotate synchronously through the meshing driving gears 8 and transmission gears 9. In this way, only one driving motor 7 needs to be set to drive all the short shafts 12 to rotate.

[0043] Embodiment 3: Refer to 4 - Figure 6 and Figures 8-9 , a roller structure for conveying brittle objects, which is basically the same as Embodiment 2. Further:

[0044] The above pressing member includes a reciprocating lead screw 16 rotatably connected to the frame 1. A reciprocating slider 17 slidably connected to the frame 1 is installed on the reciprocating lead screw 16. A first rack 18 is fixedly connected to the reciprocating slider 17. A driven gear 19 meshed with the first rack 18 is fixedly installed on the outer wall of the rotating shaft 3. A passive gear 21 is installed at the shaft end of the reciprocating lead screw 16 through a one-way bearing. A linkage member for driving the passive gear 21 to rotate is provided on the frame 1. The linkage member includes a cylinder block 13 fixedly connected to the frame 1. A piston block 14 is slidably installed in the cylinder block 13. A first spring 15 is installed between the piston block 14 and the inner top of the cylinder block 13. A second rack 20 meshed with the passive gear 21 is fixedly connected to the lower end of the piston block 14. Fine holes 26 and thick holes 27 are respectively provided at the upper and lower ends of the cylinder block 13. A blowing portion for blowing air to the inner top of the cylinder block 13 is provided on the roller shaft 6.

[0045] Specifically, when the brittle object is conveyed on the roller 6, the weight of the brittle object presses the roller 6, flattening the surface of the roller 6 in contact with the brittle object. Then, the air blowing part blows air to the inner top of the cylinder block 13, the air pressure in the cylinder block 13 increases, and is discharged through the small holes 26. The continuously rolling roller 6 squeezes a plurality of inner holes 22 in sequence, so that air is continuously conveyed into the cylinder block 13. Since the cross-sectional area of the small holes 26 is smaller than that of the exhaust pipe 25, the excess air that cannot be discharged presses the piston block 14 downward. When the thick hole 27 is not blocked by the piston block 14, the cylinder block 13 can exhaust air through the small holes 26 and the thick hole 27 at the same time. The downward moving piston block 14 drives the second rack 20 to move downward, the second rack 20 drives the driven gear 21 to rotate, the driven gear 21 drives the reciprocating lead screw 16 to rotate, the reciprocating lead screw 16 drives the reciprocating slider 17 to slide reciprocally once, the reciprocating slider 17 drives the first rack 18 to reciprocally traverse horizontally once, the first rack 18 drives the driven gear 19 to rotate forward and backward once, and the driven gear 19 drives the inclined plate 4 to swing downward and then swing upward to reset through the rotating shaft 3, and drives the roller 6 to swing downward and then swing upward to reset. Thus, when the brittle object contacts the next roller 6, the next roller 6 will swing downward in advance, which can reduce the impact force between the brittle object and the roller 6, and even there will be no impact. When the brittle object detaches from the roller 6, the roller 6 is no longer squeezed, the air blowing part no longer blows air to the cylinder block 13, the air in the cylinder block 13 is gradually emptied, and the piston block 14 slides upward to reset under the action of the first spring 15. At this time, the second rack 20 drives the driven gear 21 to reverse, and due to the action of the one-way bearing, the driven gear 21 will rotate idly in the opposite direction at the end of the reciprocating lead screw 16 and will not drive the reciprocating lead screw 16 to reverse.

[0046] Embodiment 4: Refer to Figures 3-8 , a roller structure for conveying brittle objects, which is basically the same as Embodiment 3. Further:

[0047] The above air blowing part includes inner holes 22 provided in the roller 6. A plurality of inner holes 22 are close to the circumferential outer wall of the roller 6. Annular covers 24 are fixedly connected to both inclined plates 4. The open ends of the two annular covers 24 are respectively rotatably connected to both ends of the roller 6. Both ends of the inner hole 22 are communicated with the two annular covers 24 respectively. An air suction pipe 23 and an exhaust pipe 25 are fixedly connected to the two annular covers 24 respectively. One-way valves are fixedly installed in both the air suction pipe 23 and the exhaust pipe 25. The end of the exhaust pipe 25 extends to the inner top of the cylinder block 13 of the adjacent roller 6.

[0048] When a brittle object is conveyed on the roller 6, the weight of the brittle object presses on the roller 6, flattening the surface of the roller 6 in contact with the brittle object. As a result, the space of the inner hole 22 is compressed, and a positive pressure is generated inside the inner hole 22. Since check valves are installed in the exhaust pipe 25 and the suction pipe 23, the air inside the inner hole 22 will first be discharged into the annular cover 24 and then conveyed to the inner top of the cylinder block 13 through the exhaust pipe 25, increasing the air pressure inside the cylinder block 13. When the brittle object separates from the roller 6, the roller 6 is no longer pressed, and the inner hole 22 no longer conveys air into the cylinder block 13.

[0049] A collection box 28 for collecting floating dust is fixedly connected to the bottom of the above-mentioned frame body 1. A slot 30 facing the bottom of the roller 6 is provided at the top of the collection box 28. A filter plate 29 for filtering floating dust is installed inside the collection box 28. The suction end of the suction pipe 23 extends to the inner bottom of the collection box 28. A brush plate 31 is installed inside the upper port of the collection box 28. Cleaning brushes are provided on the brush plate 31. When the roller 6 swings downward, the brush plate 31 will abut against the outer wall of the roller 6.

[0050] When the suction pipe 23 sucks air, the suction pipe 23 sucks air from the collection box 28, and the collection box 28 sucks air from the outer wall of the roller 6 through the slot 30. On the one hand, it can suck off some dust on the outer wall of the roller 6 and filter it through the filter plate 29. On the other hand, it can dissipate heat from the outer wall of the roller 6, keeping the roller 6 with good heat dissipation performance and anti-slip performance. When the roller 6 swings downward and obliquely, the roller 6 will also press against the brush plate 31, and the rotating roller 6 will be cleaned by the brush plate 31, further improving the cleaning effect of the outer wall of the roller 6. When the roller 6 swings upward and resets, the brush plate 31 will separate from the roller 6. On the one hand, it prevents the brush plate 31 from wearing the roller 6 after long-term contact with the roller 6. On the other hand, after the brush plate 31 stops contacting the roller 6, the continuously sucking slot 30 can suck off the floating dust on the brush plate 31, ensuring the continuous cleaning ability of the brush plate 31.

[0051] A horizontal pipe 38 is fixedly connected to the top of the above-mentioned frame body 1. A spray head 39 facing the outer wall of the roller 6 is fixedly installed on the outer wall of the horizontal pipe 38. The exhaust ends of the fine hole 26 and the coarse hole 27 are connected to the horizontal pipe 38 through a connecting pipe 40.

[0052] Specifically, when the fine hole 26 and the coarse hole 27 continuously exhaust air, the connecting pipe 40 will convey air to the horizontal pipe 38, and the horizontal pipe 38 will blow the air towards the surface of the brittle object through the spray head 39. Then, the air with residual heat will heat the upper end surface of the brittle object, preventing the temperature roller 6 from only heating the lower surface of the brittle object and making the upper and lower surface temperatures of the brittle object as consistent as possible, so that the brittle material is not prone to cracking.

[0053] Example 5: Refer toFigures 4-6 , a roller structure for conveying brittle objects, which is basically the same as that of Embodiment 4. Further:

[0054] A plurality of cross bars 33 are fixedly connected to the above-mentioned frame body 1. Sliding platforms 34 are slidably installed at both ends of each cross bar 33. A longitudinal roller 35 is rotatably installed at the lower end of each sliding platform 34. The longitudinal roller 35 is perpendicular to the roller shaft 6. The longitudinal roller 35 is located in the gap between two adjacent roller shafts 6. An opening and closing part for driving the two side sliding platforms 34 to open and close each other is provided on the frame body 1; the opening and closing part includes a double-headed threaded rod 32 rotatably connected to the frame body 1. External threads are provided at both ends of the double-headed threaded rod 32, and the thread directions are opposite. The two side sliding platforms 34 are respectively threadedly connected to both ends of the double-headed threaded rod 32. A driving gear 36 is fixedly installed at the shaft end of the double-headed threaded rod 32. An arc-shaped rack 37 meshed with the driving gear 36 is fixedly connected to the inclined plate 4.

[0055] Specifically, during the process of conveying brittle objects, the two side longitudinal rollers 35 can effectively limit both sides of the brittle objects, preventing obvious deflection of the brittle objects during the conveying process. When the inclined plate 4 swings up and down, the inclined plate 4 will also drive the arc-shaped rack 37 to swing up and down. The arc-shaped rack 37 will drive the driving gear 36 to rotate reciprocally. The driving gear 36 will drive the double-headed threaded rod 32 to rotate reciprocally. The double-headed threaded rod 32 will drive the two side sliding platforms 34 to approach each other and then move away and reset. Then it will drive the two side longitudinal rollers 35 to move away from each other and then approach each other again. When moving away, the brittle object can smoothly pass through the two longitudinal rollers 35. When approaching each other, the two side longitudinal rollers 35 will press against both sides of the brittle object again. In this way, it can prevent the brittle object from hitting the two side longitudinal rollers 35 and can efficiently align the brittle object.

[0056] When the present invention is in use, the driving motor 7 is started. The driving motor 7 can drive the short shaft 12 to rotate, and the short shaft 12 can drive the rotating rod 5 to rotate through the belt drive 11. The rotating rod 5 can then drive the roller shaft 6 to rotate. Multiple roller shafts 6 arranged at equal intervals can achieve the conveying work of brittle objects. When a brittle object is conveyed on the roller shaft 6, the weight of the brittle object will squeeze the roller shaft 6, flattening the surface of the roller shaft 6 in contact with the brittle object. As a result, the space of the inner hole 22 will be compressed, and a positive pressure will be generated inside the inner hole 22. Since check valves are installed in the exhaust pipe 25 and the suction pipe 23, the air inside the inner hole 22 will first be discharged into the annular cover 24, and then be conveyed to the inner top of the cylinder block 13 through the exhaust pipe 25. The air pressure inside the cylinder block 13 will increase and be discharged through the fine holes 26. The continuously rolling roller shaft 6 will cause multiple inner holes 22 to be squeezed in sequence, so that air will be continuously conveyed into the cylinder block 13. And because the cross-sectional area of the fine holes 26 is smaller than that of the exhaust pipe 25, the excess air that cannot be discharged will push the piston block 14 downward. When the thick hole 27 is not blocked by the piston block 14, the cylinder block 13 can exhaust through the fine holes 26 and the thick hole 27 at the same time. The downward moving piston block 14 will drive the second rack 20 to move downward. The second rack 20 will drive the driven gear 21 to rotate. The driven gear 21 will drive the reciprocating lead screw 16 to rotate. The reciprocating lead screw 16 will drive the reciprocating slider 17 to slide reciprocally once. The reciprocating slider 17 will drive the first rack 18 to reciprocally move horizontally once. The first rack 18 will drive the driven gear 19 to rotate forward and backward once. The driven gear 19 will drive the inclined plate 4 to swing downward and then swing upward to reset through the rotating shaft 3, and drive the roller shaft 6 to swing downward and then swing upward to reset. Thus, when the brittle object contacts the next roller shaft 6, the next roller shaft 6 will swing downward in advance, which can reduce the impact force between the brittle object and the roller shaft 6, and even there will be no impact, so that the brittle object and the roller shaft 6 are not easily damaged, and the process of conveying the brittle object will also be smoother. When a local position of the roller shaft 6 is not squeezed, the local position of the roller shaft 6 will elastically reset, and the inner hole 22 will also reset at the same time, and suck in outside air through the suction pipe 23.

[0057] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-mentioned technical content as equivalent embodiments of equivalent changes without departing from the technical solution scope of the present invention.
