Description

Technical Field

[0001] This invention relates to the technical field of rollers, specifically a belt conveyor and roller structure. Background Technology

[0002] A conveyor is a machine that continuously transports materials and is widely used in mines, factories, and other similar settings. It uses components such as conveyor belts or chains, along with a drive unit, to achieve efficient material transfer. It features large conveying capacity, stable speed, and the ability to transport materials over long distances. It reduces labor costs and improves operational efficiency, making it an indispensable key piece of equipment in modern material handling systems.

[0003] For example, Chinese Patent No. CN207985994U discloses a belt conveyor roller and a belt conveyor, including two circular end plates at both ends of the roller, a circular auxiliary plate between the two circular end plates, the circular auxiliary plate being coaxially arranged with the two circular end plates, and a through shaft passing through the two circular end plates and the circular auxiliary plate; a plurality of spaced roller strips are connected between the two circular end plates in the circumferential direction, and the middle part of the roller strips is connected to the circular auxiliary plate.

[0004] However, the aforementioned patents still have some problems. Traditional roller structures consist of a shaft, a roller, and two expansion sleeves fixed together as a whole. The drawback of this structure is that it is complex and costly. Furthermore, the expansion sleeves are prone to damage during installation and use, especially during mineral transportation. Due to the large volume and weight of minerals, the expansion sleeves are easily deformed, requiring frequent replacement. However, the unit price of the expansion sleeves is too high, thus increasing the company's costs.

[0005] Therefore, how to provide a new roller structure is a problem that needs to be solved. Summary of the Invention

[0050] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0051] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0052] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0053] This invention discloses a roller structure for a belt conveyor, with reference to... Figures 1-15 ,include:

[0054] The cylinder body 2 is an integral tubular hollow structure, and the circumferential curved surface of the cylinder body 2 is the working surface. There are two shaft heads 1, which are symmetrically arranged along the length of the cylinder body 2. The shaft heads 1 are also provided with grooves. The shaft heads 1 are placed at both ends of the cylinder body 2 and welded to the cylinder body 2. The grooves are connected to the hollow structure on the cylinder body 2 to form a cavity. By welding the shaft heads 1 to the cylinder body 2, the use of shafts and accounting sets is reduced. This avoids the need to replace the accounting sets when they are damaged during operation, thereby reducing the economic losses of the enterprise.

[0055] There are two connecting rollers 3 to ensure that the shaft and the cylinder are connected as one piece. The connecting rollers 3 are located inside the cylinder and are used to support the cylinder. The cylinder is welded together to form a roller structure. The reinforcing ribs 4 can support the cylinder and increase the strength of the roller.

[0056] The belt conveyor 6 includes at least two roller structures, and further includes: a conveyor body 6 connected to the roller structures, for transporting items by dropping them onto the conveyor belt; a dynamic scraping unit 5 located on the conveyor body 6, for dynamically cleaning the non-working surface of the conveyor belt when the conveyor belt is working; and a cleaning unit 7 fixedly installed on the conveyor 6 for cleaning the conveyor belt when it is not in operation. Through the dynamic scraping unit 5, during the operation of the conveyor belt, the dynamic scraping unit 5 can clean the non-working surface of the conveyor belt, i.e., the return section (lower surface) of the belt.

[0057] The dynamic scraping unit 5 includes a connecting plate 51 mounted on the conveyor 6, a sleeve 52 and a connecting shaft 53 slidably connected to the connecting plate 51, a scraper 55 fixedly connected to the sleeve 52 and the connecting shaft 53 respectively, and a connecting spring 54 sleeved on the connecting shaft 53 for connecting the connecting plate 51 and the scraper 55. The scraper 55 is triangular in shape and has at least two guide grooves 56. When installing the conveyor 6, the connecting plate 51 can be placed on the conveyor 6. By adjusting the installation position of the connecting plate 51, the connecting spring 54 is in a deformed state, so that the scraper 55 can contact the conveyor belt. During the belt movement, the scraper 55 can contact the surface of the belt and scrape off the dirt attached to the belt surface. The scraped dirt can move along the guide grooves 56 and move away from the conveyor belt, thus completing the cleaning of the conveyor belt.

[0058] The cleaning unit 7 includes a smoothing component 71, a scraping component 72, a detection component 73, and a rejection component 74, which are sequentially arranged on the conveyor 6 along the rotation direction of the conveyor belt. There are two smoothing components 71, and the scraping component 72, detection component 73, and rejection component 74 are located between the two smoothing components 71. Each smoothing component 71 includes a smoothing seat on the conveyor 6, a first motor 711, a drive shaft 715, and a driven shaft 717 located on the smoothing seat, a first gear 712 mounted on the drive shaft 715, a second gear 713 mounted on the smoothing seat and meshing with the first gear 712, a third gear 714 connected to the driven shaft 717 and meshing with the second gear 713, a plurality of first drive wheels 716 evenly mounted on the drive shaft 715, and a plurality of lifting members 71 mounted on the driven shaft 717. 8; The output end of the first motor 711 is connected to the drive shaft 715; The lifting member 718 includes a connecting seat 7181 fixedly installed on the smoothing seat, a lifting cylinder 7182 movably connected to the connecting seat 7181, a support 7183 movably connected to the output end of the lifting cylinder 7182 and sleeved on the driven shaft 717, a fourth gear 7184 sleeved on the driven shaft 717 and located in the support 7183, a hollow shaft 7186 disposed in the support 7183, a fifth gear 7185 and a second drive wheel 7187 respectively sleeved on the hollow shaft 7186, and a laser detection device fixedly installed on the conveyor 6; The laser detection device generates laser light and passes the laser light through the hollow shaft 7186 to detect the location of dirt on the belt; The fourth gear 7184 meshes with the fifth gear 7185.

[0059] When belt cleaning is required, the conveyor 6 is stopped, and the tensioning unit is adjusted to loosen the belt. Then, the lifting cylinder 7182 starts working. The moving lifting cylinder 7182 drives the support 7183 to rotate around the driven shaft 717. The moving support 7183 drives the second drive wheel 7187 to rotate, allowing the second drive wheel 7187 to contact the belt. Then, the first motor 711 starts working. The moving first motor 711 drives the first gear 712 to rotate, thereby driving the second gear 713 and the third gear 714 to rotate. The moving first gear 712 and the third gear 714 drive the drive shaft 715 and the driven shaft 717 to rotate. The moving multi-functional shaft drives the first drive wheel 716 to rotate. At this time, the belt is located between the two drive wheels. The rotation of the first drive wheel 716 and the second drive wheel 7187 can transport and straighten the belt.

[0060] During this process, the rotation speed and rotation direction of the first motor 711 in the two smoothing components 71 are different. Initially, the rotation speed of the first motor 711 is opposite to that of the first motor 711, thereby completing the straightening of the belt. Then, the rotation speed of the first motor 711 increases, so that the belt can move and avoid large wrinkles on the belt, which would cause the stain removal work to fail.

[0061] When the belt is slack, the contact pressure is adjusted by the cylinder to ensure effective transport of the belt by the drive wheel without damaging the belt due to excessive pressure. In addition, the hollow shaft 7186 works in conjunction with the laser detection device to allow the laser to pass through the hollow shaft 7186. When the laser receiving device does not receive a signal, it indicates that the area needs to be cleaned.

[0062] The scraping assembly 72 includes a frame 721 fixedly mounted on the conveyor 6, a drive motor 722 and a drive wheel 723 mounted on the frame 721, a drive belt for connecting the output end of the drive motor 722 to the drive wheel 723, a rotating rod 724 connected to the drive wheel 723, a rotating wheel 725 mounted at one end of the rotating rod 724, an adjusting rod 726 abutting against the rotating wheel 725 and movably connected to the frame 721, a scraper 728 mounted on the adjusting rod 726, and an elastic connector 727 for connecting the frame 721 and the adjusting rod 726.

[0063] After the smoothing component 71 completes the flattening of the belt, the drive motor 722 starts working. The moving drive motor 722 drives the drive wheel 723 to rotate via the drive belt. The moving drive wheel 723 then drives the rotating rod 724 to move, which in turn drives the rotating wheel 725 to move. The rotating wheel 725 contacts the adjusting rod 726, thereby changing the position of the scraper 728 so that the scraper 728 can contact the belt and scrape away the dirt on the belt. This prevents the belt from deforming too much due to long-term use, which would prevent the dynamic scraping unit 5 from cleaning the surface of the belt while it is in operation, thus avoiding the accumulation of a large amount of dust on the belt surface.

[0064] The detection assembly 73 includes a frame fixedly mounted on the conveyor 6, a bidirectional motor 731 fixedly mounted on the frame, a rod connected to the output end of the bidirectional motor 731, two swing arms 732 symmetrically arranged on the rod, a first swing rod 733 and a second swing rod 734 movably connected to the swing arms 732, a limiting rod 735 fixedly mounted on the frame, a first lifting plate 736 and a second lifting plate 737 arranged on the limiting rod 735, and a plurality of detection parts 75 respectively arranged on the first lifting plate 736 and the second lifting plate 737; the detection part 75 includes a connecting frame 751 connected to the first lifting plate 736, a first connecting rod 756 movably connected to the connecting frame 751, a movable frame 752 movably connected to the connecting frame 751, a first abutting wheel 753 connected to the movable frame 752, and a first abutting wheel 753 for connecting two of the first abutting wheels 753 close to the first abutting wheel 753. The device includes a third link 759 of a first link 756, two second abutment wheels 758 on the other two first links 756, a second link 757 for connecting the first links 756 at different distances from the first abutment wheels 753, a first spring 754 for connecting the movable frame 752 and the third link 759, and a second spring 755 for connecting the connecting frame 751 and the third link 759; two first swing rods 733 are respectively connected to the first lifting plate 736, and two second swing rods 734 are disposed on the second lifting plate 737; the device also includes a visual inspection device, which can detect the protruding ends on the belt, thereby detecting some impurity areas embedded in the belt; a connecting shaft 53 is provided between the two first links 756 connected to the second abutment wheels 758 and the two first links 756 connected to the third link 759, and the connecting shaft 53 is located on the connecting frame 751;

[0065] When it is necessary to locate and detect impurities on the belt, the bidirectional motor 731 starts to work. The moving bidirectional motor 731 can drive the rod to rotate, and then the moving rod can drive the swing arm 732 to move. At this time, the moving swing arm 732 can drive the first swing rod 733 and the second swing rod 734 to move. At this time, the moving first swing rod 733 and the second swing rod 734 can drive the first lifting plate 736 and the second lifting plate 737 to move closer or further apart, so that the detection unit 75 can be brought closer to the belt.

[0066] When the detection unit 75 approaches the belt, and encounters a raised area (dusty area), the first abutment wheel 753 is lifted. The first abutment wheel 753, via the movable frame 752, changes the deformation of the first spring 754. The first spring 754 then drives the third connecting rod 759, causing one of the connecting shafts 53 to rotate. The rotating connecting shaft 53 then causes the second abutment wheel 758 to move. At this point, the first abutment wheel 753 moves away from the belt, while the second abutment wheel 758 moves closer to the belt, thus stopping the belt or slowing down the belt drive speed. To ensure the visual inspection device can complete its inspection work, when there are minerals or other impurities embedded inside the belt, the rejection unit 748 starts working to remove some of the impurities embedded in the belt. Conversely, if the belt stops due to excessive dust, the bidirectional motor 731 starts working, moving the inspection unit 75 away from the belt. Then, the main control system marks the area. After the belt rotates one revolution, the scraper 728 scrapes away the dust to prevent the lower surface of the belt from contacting the roller during operation, which would cause the dust to be compacted and increase the difficulty of cleaning.

[0067] The rejection assembly 74 includes a detection frame 741 mounted on the conveyor 6, at least two linear motion mechanisms 742 fixedly connected to the detection frame 741, a drive block 743 disposed on the linear motion mechanism 742, a slide rail 746 disposed on the detection frame 741, a driven block 744 slidably connected to the slide rail 746, an inclined plate 745 disposed on the driven block 744, a lifting block 747 connected to the driven block 744, a rotating motor 7410 fixedly mounted on the lifting block 747, a rotating shaft 749 connected to the rotating motor 7410, and a plurality of rejection parts 748 disposed on the rotating shaft 749; the front end of the drive block 743 has a protrusion, which abuts against the inclined plate 745; the rejection part 748 includes a drive block 743 mounted on the conveyor 6, a slide rail 746 fixedly connected to the slide rail 746, a driven block 744 slidably connected to the slide rail 746, a driven plate 745 fixedly connected to the driven block 746, a driven plate 746 fixedly connected to the driven block 746, a driven plate 744 slidably ... The rotating shaft 749 is connected to a mounting base 7481, symmetrically arranged support wheels 7482 on the mounting base 7481, two moving cylinders 7484 built into the mounting base 7481, an adjusting block 7485 connected to the output end of the moving cylinders 7484, a plurality of moving rods 7486 movably connected to the adjusting block 7485, a plurality of moving seats 7487 connected to the moving rods 7486, a first support wheel 7482 movably connected to the moving seat 7487, a second support rod 7483 connected to the first support wheel 7482 and arranged on the mounting base 7481, a moving wheel 7489 located at the first support wheel 7482 and the second support wheel 7482, and a return spring 74810 for connecting the moving seat 7487 and the mounting base 7481;

[0068] When the rejection assembly 74 needs to be used, the linear motion mechanism 742 starts working, causing the drive block 743 to move on the inclined plate 745, thereby pushing the driven block 744 to move along the length of the slide rail 746. The moving driven block 744 can adjust the height of the lifting block 747, so that the rejection part 748 on the rotating shaft 749 can contact the belt surface. One rejection part 748 contacts the upper surface of the belt, and the other contacts the lower surface. Then, the moving cylinder 7484 in the lower rejection part 748 starts working. The moving moving cylinder 7484 can drive the adjusting block 7485 to work. The moving adjusting block 7485 drives the movable rod 7486 to move, thereby driving the first support rod 7488 to move, thus changing the position of the belt. The angle between the first support rod 7488 and the second support rod 7483 lifts the belt, causing it to deform and exposing some of the ore embedded in the belt. Then, the rotating motor 7410 rotates another rejection section 748, allowing the movable wheel 7489 in the rejection section 748 to contact the ore, thereby completing the rejection work. This rejection work can remove ore from both the upper and lower surfaces of the belt. At the same time, by changing the angle between the first support rod 7488 and the second support rod 7483, the deformation of the belt can be increased (at this time, the smoothing component 71 needs to cooperate to avoid the belt becoming too flat), allowing embedded impurities to be exposed and then contacting the other rejection section 748. The centrifugal force then completes the rejection work for the impurities.

[0069] In the removal section 748, the moving cylinder 7484 drives the adjusting block 7485, and the movable rod 7486 changes the angle of the first and second support rods 7483. This can both lift the belt to deform it and expose the embedded ore, and control the belt deformation by adjusting the angle. Combined with the "not completely flat" state of the smoothing component 71, it can force the embedded impurities to be exposed, solving the problem that traditional removal devices are difficult to handle deep impurities. It can simultaneously process impurities on both sides of the belt, avoiding the limitations of unidirectional cleaning. It is especially suitable for scenarios where impurities may be contaminated on both sides or the position of embedded impurities is uncertain. At the same time, this device first deforms the belt by adjusting the angle of the support rods to force the impurities to be exposed, and then generates centrifugal force through the rotating removal section 748 to efficiently peel off the stubborn attached impurities.

[0070] In a further embodiment, the output end of the drive motor 722 is provided with a conveyor wheel, the elastic connector 727 and the laser detection device are existing technologies, and the detection frame 741 is mounted on the conveyor 6 through a lead screw linear motion mechanism 742.

[0071] To ensure the proper fit between the rollers in this device and existing rollers, simulation tests were also conducted, including:

[0072] First, the structure of this device is abstracted as a simply supported beam model for analysis. Figure 15 Then, taking the axial direction of the roller as the Y-axis and the radial direction as the X-axis, while keeping other conditions unchanged:

[0087] Working principle description: When installing the conveyor 6, the connecting plate 51 can be placed on the conveyor 6. By adjusting the installation position of the connecting plate 51, the connecting spring 54 is in a deformed state, so that the scraper 55 can contact the conveyor belt. Then, during the belt movement, the scraper 55 can contact the surface of the belt and scrape off the dirt attached to the belt surface. The scraped dirt can move along the guide groove 56 and move away from the conveyor belt, thus completing the cleaning of the conveyor belt.

[0088] When belt cleaning is required, the conveyor 6 is stopped, and the tensioning unit is adjusted to loosen the belt. Then, the lifting cylinder 7182 starts working. The moving lifting cylinder 7182 drives the support 7183 to rotate around the driven shaft 717. The moving support 7183 drives the second drive wheel 7187 to rotate, allowing the second drive wheel 7187 to contact the belt. Then, the first motor 711 starts working. The moving first motor 711 drives the first gear 712 to rotate, thereby driving the second gear 713 and the third gear 714 to rotate. The moving first gear 712 and the third gear 714 drive the drive shaft 715 and the driven shaft 717 to rotate. The moving multi-functional shaft drives the first drive wheel 716 to rotate. At this time, the belt is located between the two drive wheels. The rotation of the first drive wheel 716 and the second drive wheel 7187 can transport and straighten the belt.

[0089] After the smoothing component 71 completes the smoothing work on the belt, the drive motor 722 starts to work. The moving drive motor 722 can drive the drive wheel 723 to rotate through the set drive belt. Then the moving drive wheel 723 can drive the rotating rod 724 to move. Then the moving rotating rod 724 can drive the rotating wheel 725 to move. The rotating wheel 725 contacts the adjusting rod 726, thereby changing the position of the scraper 728, so that the scraper 728 can contact the belt and scrape off the dirt on the belt.

[0090] When it is necessary to locate and detect impurities on the belt, the bidirectional motor 731 starts to work. The moving bidirectional motor 731 can drive the rod to rotate, and then the moving rod can drive the swing arm 732 to move. At this time, the moving swing arm 732 can drive the first swing rod 733 and the second swing rod 734 to move. At this time, the moving first swing rod 733 and the second swing rod 734 can drive the first lifting plate 736 and the second lifting plate 737 to move closer or further apart, so that the detection unit 75 can be brought closer to the belt.

[0091] When the detection unit 75 approaches the belt, and encounters a raised area (dusty area), the first abutment wheel 753 can be lifted. Then, the first abutment wheel 753 can change the deformation of the first spring 754 through the movable frame 752. The first spring 754 can drive the third connecting rod 759 to move, thereby driving one of the connecting shafts 53 to rotate. The moving connecting shaft 53 can then cause the second abutment wheel 758 to move. At this time, the first abutment wheel 753 moves away from the belt, while the second abutment wheel 758 moves closer to the belt, thereby completing the belt stopping work or slowing down the belt transmission speed, thus ensuring that the vision inspection device can complete the inspection work.

[0092] When the rejection assembly 74 needs to be used, the linear motion mechanism 742 starts working, causing the drive block 743 to move on the inclined plate 745, thereby pushing the driven block 744 to move along the length of the slide rail 746. The moving driven block 744 can adjust the height of the lifting block 747, so that the rejection part 748 on the rotating shaft 749 can contact the belt surface. One rejection part 748 contacts the upper surface of the belt, and the other contacts the lower surface. Then, the moving cylinder 7484 in the lower rejection part 748 starts working. The moving moving cylinder 7484 can drive the adjusting block 7485 to work. The moving adjusting block 7485 drives the movable rod 7486 to move, thereby driving the first support rod 7488 to move, thus changing the position of the belt. The angle between the first support rod 7488 and the second support rod 7483 lifts the belt, causing it to deform and exposing some of the ore embedded in the belt. Then, the rotating motor 7410 rotates another rejection section 748, allowing the movable wheel 7489 in the rejection section 748 to contact the ore, thereby completing the rejection work. This rejection work can remove ore from both the upper and lower surfaces of the belt. At the same time, by changing the angle between the first support rod 7488 and the second support rod 7483, the deformation of the belt can be increased (at this time, the smoothing component 71 needs to cooperate to avoid the belt becoming too flat), allowing embedded impurities to be exposed and then contacting the other rejection section 748. The centrifugal force then completes the rejection work for the impurities.
