Description

Technical Field

[0001] This invention belongs to the field of tape conveyors, and specifically relates to a non-powered rotating tape cleaner for tape conveyors. Background Technology

[0002] Belt conveyors are widely used in mining, metallurgy, and other fields. A common problem is material sticking to the belt during return trips, causing spillage in the conveyor belt corridor. Currently, the main cleaning devices used in the industry are friction scraper type, electric roller brush type, and non-powered friction roller brush type. Existing technologies each have the following problems:

[0003] Among them, friction scraper is the most commonly used. Problems: the scraper is prone to uneven wear during scraping, which creates gaps between it and the belt contact surface. Gravity or spring compensation cannot eliminate these gaps, resulting in incomplete cleaning. The scraper can easily damage belt bonding or cold-fastened joints. It can also cause secondary damage to repaired belts or belts with surface defects.

[0004] Electric roller brush conveyors are not widely used in the industry. Problems include: complex design and high price; high operating costs; and large-scale continuous production enterprises with numerous conveyor belts are unlikely to adopt this type of equipment.

[0005] The problems with non-powered friction roller brushes are: large size, complex design, and inconvenient installation and maintenance. Summary of the Invention

[0006] To address the aforementioned problems, this invention discloses a non-powered rotating adhesive strip cleaner for tape machines. The adhesive strip cleaner includes a roller mounted on a support frame, multiple adhesive strips wrapped around the roller, and a preload adjustment mechanism mounted on the support frame.

[0007] The support frame is provided with adjustment holes, and the rotating shafts at both ends of the roller are slidably installed in the adjustment holes on the support frame. The preload adjustment device passes through the support frame and is used to adjust the position and height of the rotating shaft of the roller in the adjustment holes, and also to adjust the distance between the rubber strip cleaner and the conveyor belt of the conveyor belt machine.

[0008] Furthermore, bearings are installed on the rotating shafts at both ends of the roller, the bearings are mounted on sliding bearing seats, and the sliding bearing seats are slidably mounted on the support frame.

[0009] Furthermore, the preload adjustment mechanism includes an adjusting rod mounted on the support frame, an adjusting nut threadedly engaged with the adjusting rod, and an elastic element sleeved on the adjusting rod;

[0010] The adjusting rod is slidably mounted on the support frame. One end of the adjusting rod passes through the support frame and is mounted on the sliding bearing seat. An adjusting nut is threaded onto the other end of the adjusting rod. The elastic element is disposed between the adjusting nut and the support frame.

[0011] Furthermore, multiple adjusting nuts are installed on the other end of the adjusting rod.

[0012] Furthermore, the adhesive strips are inclinedly disposed on the surface of the roller, and multiple adhesive strips are evenly distributed along the circumference of the roller to form an adhesive ring, and multiple adhesive rings are distributed along the axial direction of the roller.

[0013] Furthermore, the rubber strips in two adjacent rubber rings are installed on the roller in a staggered manner.

[0014] In another aspect, the present invention also discloses a tape machine, the tape machine comprising a tape cleaner as described in any one of the claims, a drive roller rotatably mounted on an external frame, a tape sleeved on the drive roller, and a drainer mounted on the external frame;

[0015] The drive roller drives the conveyor belt to rotate, conveying the material on the conveyor belt to the top of the funnel, where the material falls into the funnel; the rubber strip cleaner is installed on the funnel, and the rubber ring on the rubber strip cleaner contacts the conveyor belt.

[0016] Furthermore, the support frames at both ends of the rubber strip cleaner are installed on the outside of the leak.

[0017] Furthermore, multiple mounting holes for installing adhesive strip cleaners are provided on both sides of the leak.

[0018] Furthermore, the preload adjustment mechanism on the rubber strip cleaner is installed on the outside of the leak, avoiding the direction of material falling on the conveyor belt.

[0019] Furthermore, the tilt direction of the adhesive strip on the adhesive strip cleaner is opposite to the direction of movement of the adhesive belt.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] This invention provides a non-powered rotary conveyor belt cleaner and a conveyor belt machine. The conveyor belt cleaner features independent, crisscrossed strips densely distributed on the cleaner roller. Each individual strip has a large deformation capacity, allowing it to independently compensate for localized wear, thus avoiding the gaps created by friction scrapers. The strips exhibit good elastic deformation, resulting in minimal relative displacement when in contact with the conveyor belt surface. This significantly reduces the damage caused by continuous large-area friction from friction scrapers to belt bonding or cold-fastened joints, and also minimizes secondary damage to repaired belts or belts with surface defects. This invention's conveyor belt cleaner requires no electricity, has low manufacturing costs, and is compact in design, easy to install, and requires minimal maintenance.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Figure 1 A schematic diagram of a non-powered rotating adhesive strip cleaner for a tape machine is shown in an embodiment of the present invention. The non-powered rotating adhesive strip cleaner for a tape machine includes a roller 5 mounted on a support frame 10, multiple adhesive strips 1 wrapped around the roller 5, and a pre-tension adjustment mechanism mounted on the support frame 10. The support frame 10 is provided with adjustment holes 11. The rotating shafts at both ends of the roller 5 are slidably mounted within the adjustment holes 11 on the support frame 10. The pre-tension adjustment mechanism penetrates the support frame 10 and is used to adjust the position and height of the rotating shafts of the roller 5 within the adjustment holes 11, and also to adjust the distance between the adhesive strip cleaner and the tape 7 of the tape machine. Figure 1 As can be seen, the shape of the adjustment hole 11 is an oblong hole.

[0035] Figure 3 The diagram shows a left view of the unpowered rotating adhesive strip cleaner for a tape machine according to an embodiment of the present invention. Bearings are mounted on the rotating shafts at both ends of the roller 5. The bearings are mounted on sliding bearing seats 2, which are slidably mounted on a support frame 10. The support frame 10 is provided with guide rails for the sliding bearing seats 2 to slide, preventing the sliding bearing seats 2 from wobbling left and right and allowing adjustment only in the vertical direction.

[0036] Figure 2 This invention shows a front view of a non-powered rotating adhesive strip cleaner for a tape machine in an embodiment of the present invention. The pre-tension adjustment mechanism includes an adjusting rod mounted on a support frame 10, an adjusting nut 3 threadedly engaged with the adjusting rod, and an elastic element sleeved on the adjusting rod; as shown... Figure 3 The adjusting rod is slidably mounted on the support frame 10. One end of the adjusting rod passes through the support frame 10 and is mounted on the sliding bearing seat 2. An adjusting nut 3 is threaded onto the other end of the adjusting rod. The elastic element is disposed between the adjusting nut 3 and the support frame 10. Furthermore, multiple adjusting nuts 3 can be mounted on the other end of the adjusting rod. When the height of the roller 5 needs to be adjusted, rotating the adjusting nut 3 moves the adjusting rod up or down, thereby causing the sliding bearing seat 2 to move up and down, completing the height adjustment of the roller 5. Multiple adjusting nuts 3 are provided because they create mutual obstruction and compression, effectively preventing the adjusting nuts 3 from loosening and rotating due to vibration during equipment operation. The elastic element in the preload adjustment mechanism can be, for example,... Figure 3The spring 4 shown can also be made of other elastic components, such as spring sheets, rubber sleeves, or corrugated sleeves.

[0037] like Figure 2 and Figure 4 ,in Figure 4 It shows Figure 2 The cross-sectional view at point A-A shows that the adhesive strips 1 are obliquely arranged on the surface of the roller 5. Multiple adhesive strips 1 are evenly distributed along the circumference of the roller 5 to form an adhesive ring, and multiple adhesive rings are distributed along the axis of the roller 5. Furthermore, the adhesive strips 1 in adjacent adhesive rings are staggered on the roller 5. Additionally, depending on the actual situation, the shape of the roller 5 does not necessarily have to be a regular circle; it can be spindle-shaped or hourglass-shaped. The adhesive strips 1 can be fixed to the roller 5, and their distribution on the roller 5 can be uniform or uneven. For example, when material conveying mostly uses the middle part of the conveyor belt 7, the adhesive strips 1 in the middle of the roller 5 can be more numerous and densely distributed, while the adhesive strips on both sides can be sparsely distributed. This uneven distribution of adhesive strips 1 allows for better cleaning of the conveyor belt 7, and the cleaning ability can be adjusted as needed.

[0038] like Figure 5 and Figure 6 As shown, a tape conveyor machine includes the aforementioned tape cleaner 6, a drive roller 8 rotatably mounted on an external frame, a tape 7 sleeved on the drive roller 8, and a drain 9 mounted on the external frame. The drive roller 8 drives the tape 7 to rotate, conveying the material on the tape 7 to above the drain 9, where the material falls into the drain 9. The tape cleaner 6 is mounted on the drain 9, and the rubber ring on the tape cleaner 6 contacts the tape 7. When installing the tape cleaner 6, it can be installed on the drain 9 first, and then the pre-tension adjustment mechanism on the tape cleaner 6 can be operated to adjust the distance between the tape cleaner 6 and the tape 7, so that the tape 1 on the tape cleaner 6 is in close contact with the tape 7, or even in a state of being squeezed and deformed. At this time, the spring 4 in the preload adjustment mechanism is in a compressed state. That is to say, when the roller 5 is squeezed and moves downward, the height of the roller 5 will still return to the initial state under the action of the spring 4. In addition, the spring 4 causes the rubber strip 1 on the roller 5 to be squeezed with the tape 7, increasing the cleaning ability of the rubber strip 1 on the tape 7.

[0039] The support frames 10 at both ends of the rubber strip cleaner 6 are installed on the outside of the funnel 9 to prevent the support frames 10 from blocking the material from falling into the funnel 9.

[0040] The drain 9 has multiple mounting holes on both sides for installing the rubber strip cleaner 6. The positions and heights of the multiple mounting holes are staggered to allow the rubber strip cleaner 6 to be installed in different positions for cleaning different working conditions or different materials.

[0041] The pre-tension adjustment mechanism on the rubber strip cleaner 6 is installed on the outside of the funnel 9, avoiding the falling direction of the material transported on the conveyor belt 7, to prevent the material from falling into the pre-tension adjustment mechanism. Impurities may get stuck in the pre-tension adjustment mechanism or the sliding bearing seat 2, hindering the operation of both and preventing the smooth adjustment of the position of the roller 5.

[0042] Figure 7 This diagram illustrates the working principle of a non-powered rotating adhesive strip cleaner in an embodiment of the present invention. The inclination direction of the adhesive strip 1 on the cleaner 6 is opposite to the movement direction of the adhesive belt 7. This arrangement and installation of the roller 5 aims to increase the cleaning ability of the adhesive strip 1 on the adhesive belt 7. Figure 7 As can be seen, when the drive roller 8 drives the belt 7 to rotate clockwise, if the friction between the belt 7 and the rubber strip 1 is small, the rubber strip cleaner 6 does not rotate or rotates asynchronously with the belt 7, meaning the rotation of the rubber strip cleaner 6 lags behind the belt 7. At this time, it is equivalent to the rubber strip 1 tilting and "piercing" the surface of the belt 7, which has a strong cleaning effect on the material adhering to or accumulating on the belt 7. When there is a lot of material accumulated on the belt 7 or the friction between the belt 7 and the rubber strip 1 is large, the rubber strip cleaner 6 rotates synchronously with the belt 7. At this time, when the rubber strip is compressed, it squeezes the accumulated material, making the material loose. When the rubber strip 1 gradually separates from the belt 7, the rubber strip 1 will quickly return to its original shape under its own elasticity. In the process of rebounding and returning to its original shape, the rubber strip 1 will bounce the compressed and loosened accumulated material off the belt 7, achieving the cleaning effect.

[0043] The working principle of the non-powered rotary tape cleaner for conveyor belts: The pre-tension adjustment mechanism adjusts the compression deformation of the tape 1 and the conveyor belt 7, generating friction for the rotating cleaner drum 5. When the friction is sufficiently large, the conveyor belt 7 drives the cleaner drum 5 to rotate. When the tape 1 approaches the conveyor belt 7, it disrupts the accumulated material adhering to the belt 7, causing it to fall off naturally – this is the first cleaning. After contacting the conveyor belt 7, the tape 1 undergoes compression deformation, crushing the trapped material and causing it to fall off naturally – this is the second cleaning. During the compression process, the tape 1 moves on the contact surface with the conveyor belt 7, cleaning stubborn accumulated material – this is the third cleaning. As the cleaner drum 5 rotates, the compressed tape 1 continuously retracts, gradually restoring its original shape during this process, cleaning the accumulated material on the conveyor belt 7 again – this is the fourth cleaning. The drive roller 8 drives the conveyor belt 7 to move continuously, and the conveyor belt 7 drives the sweeper roller 5 to rotate. The rubber strips 1 on the roller 5 are constantly squeezed and moved by the surface of the conveyor belt 7, thereby realizing the function of the sweeper continuously cleaning the accumulated material on the surface of the conveyor belt 7 through the power of the drive roller 8. The swept material falls continuously into the gap between the rubber strips 1 of the sweeper, and falls into the drain 9 as the sweeper roller 5 rotates, thus completing the cleaning of the conveyor belt 7.

[0044] The present invention provides a non-powered rotating tape cleaner for tape machines, which solves the problems existing in the main cleaners used in the industry.

[0045] Addressing the problems of friction scraper-type conveyors: The scraper blade wears unevenly during scraping, creating gaps between it and the belt contact surface. Gravity or spring compensation cannot eliminate these gaps, resulting in incomplete cleaning; the scraper blade can easily damage the belt surface or cold-fastened joints; and it can cause secondary damage to repaired belts or belts with surface defects. The rubber strip of this invention is independent, such as... Figure 4 As shown, the rubber strips 1 are densely distributed on the sweeper roller 5 in a crisscross pattern. Each individual rubber strip 1 has a large deformation capacity and can independently compensate for local wear, thus avoiding the gaps caused by the friction scraper. The rubber strip 1 has good elastic deformation and a small relative displacement when in contact with the belt surface, which greatly reduces the continuous large-area friction caused by the friction scraper and the damage to the belt bonding or cold-fastened joints, as well as the secondary damage that can easily occur to repaired belts or belts with potential surface defects.

[0046] The problems with electric roller brush conveyors include: complex design and high price; high operating costs (e.g., electricity bills); and large-scale continuous production enterprises with numerous conveyor belt machines are unlikely to adopt this type of equipment. This invention eliminates electricity costs and has lower manufacturing costs.

[0047] The problems with non-powered friction roller brushing systems include large size, complex design, and inconvenient installation and maintenance. This invention features a compact design, easy installation, and minimal maintenance.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
