Description

Technical Field

[0001] This invention relates to the field of sand making and conveying equipment technology, and in particular to a conveyor belt roller for a sand making machine. Background Technology

[0002] Nowadays, with the construction of a large number of buildings, the materials used for building construction also need to be manufactured in large quantities. In the construction process, sand and gravel are one of the essential basic materials. However, as the consumption of construction sand and gravel continues to increase, the mining of natural sand faces the pressure of resource depletion and environmental protection. Under such circumstances, the use of artificial sand has become the main type of construction sand in the future market. The processing and production of artificial sand requires the use of sand making machines. During the use of sand making machines, conveyors are needed to transport and transfer the finished sand and gravel. Conveyors are generally composed of rollers and conveyor belts.

[0003] After prolonged use, the friction between the rollers and the conveyor belt may decrease. Once the friction decreases to a certain value, with the weight of the conveyed sand and gravel remaining constant, the rollers may rotate but fail to move the conveyor belt. In this case, the sand making machine needs to be stopped and the conveyor needs to be repaired. Repairing the conveyor often takes a long time, which seriously affects the efficiency of sand making.

[0004] In the prior art, there is a direct-adhesion ceramic patch conveyor belt roller (publication number: CN112499121B), whose structure includes a roller, ceramic patches and an adhesive layer. The roller is connected to the ceramic patches through the adhesive layer, and the surface of the ceramic patches is provided with anti-slip protrusions. This invention is used to increase the friction between the roller and the conveyor belt. Although this direct-adhesion ceramic patch conveyor belt roller can increase the friction between the roller and the conveyor belt, the friction will gradually decrease during long-term use, which may lead to the roller being unable to drive the conveyor belt to move. As a result, it is necessary to stop the conveyor and perform maintenance while it is in operation, which affects the efficiency of sand making.

[0005] Therefore, it is necessary to provide a conveyor belt roller for a sand making machine to solve the above-mentioned technical problems. Summary of the Invention

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] First Embodiment

[0034] Please refer to the following: Figures 1-4In the first embodiment of the present invention, the conveyor belt roller of the sand making machine includes: a roller 1 and two rotating rollers 2. The roller 1 is constructed with a hollow structure. Both sides of the roller 1 have openings. Two fixing rings are fixedly installed on the inner wall of the roller 1. Connecting discs are fixedly installed on the outer walls of the two rotating rollers 2 on their adjacent sides. Both connecting discs extend into the roller 1. The two connecting discs are respectively connected to the two fixing rings by multiple mounting bolts. This arrangement facilitates the separation of the roller 1 and the rotating rollers 2. Multiple sliding grooves 8 are provided on the outer wall of the roller 1. The sliding channels 8 are staggered. Multiple support plates 9 are slidably installed on the inner wall of the roller 1. The outer walls on both sides of the support plates 9 are arc-shaped. The arc of the outer walls on both sides of the support plates 9 is adapted to the inner wall of the roller 1 and the outer wall of the unfolded pushing airbag 4, respectively. Multiple support blocks 11 are fixedly installed on one side of the outer wall of the multiple support plates 9. One side of the multiple support blocks 11 extends into the multiple sliding channels 8. Ceramic patches 12 are fixedly installed on one side of the outer wall of the multiple support blocks 11. The ceramic patches 12 are constructed using existing technology. The roller 1 is provided with a support plate pushing mechanism.

[0035] Support frames 3 are provided on both sides of the roller 1. The ends of the two rotating rollers 2 that are far apart from each other pass through the two support frames 3 and are rotatably connected to the two support frames 3 respectively. One end of one of the rotating rollers 2 is provided with an installation hole.

[0036] The support plate pushing mechanism includes: a pushing airbag 4, an air pump 5, a rotary joint 6, and an air supply pipe 7. The pushing airbag 4 is installed inside the roller 1 and is made of rubber. Multiple straps are fixedly installed on both outer walls of the pushing airbag 4. The multiple straps are connected to multiple support plates 9 by multiple screws. The air pump 5 is fixedly installed on one outer wall of the support frame 3 near the rotating roller 2 with the installation hole. The rotary joint 6 is fixedly installed on one outer wall of the support frame 3 near the air pump 5. An L-shaped connecting plate is fixedly installed on one outer wall of the support frame 3. One outer wall of the L-shaped connecting plate is connected to the rotary joint 6. One end of the rotary joint 6 is connected to the air outlet pipe on the air pump 5. The rotary joint 6 is constructed using existing technology. The air supply pipe 7 is installed in the installation hole. One end of the air supply pipe 7 is connected to the air pump 5, and the other end of the air supply pipe 7 is connected to the end of the rotary joint 6 away from the air outlet pipe.

[0037] Two limiting members 10 are slidably installed on the support plate 9. One end of each limiting member 10 is fixedly connected to the inner wall of the roller 1. Each limiting member 10 includes a sliding rod and a limiting block. The limiting block is fixedly installed on one end of the sliding rod. Two sliding holes are opened on one side of the outer wall of the support plate 9. The two sliding rods pass through the two sliding holes and are slidably connected to the inner walls of the two sliding holes respectively. Each limiting member 10 is fitted with a reinforcing spring 13. One end of each reinforcing spring 13 is connected to one side of the outer wall of the support plate 9, and the other end of each reinforcing spring 13 is connected to one side of the outer wall of the two limiting members 10 respectively. The elastic pull of the reinforcing spring 13 can ensure the stability of the support plate 9 during the rotation of the roller 1.

[0038] In this embodiment:

[0039] In use, the roller 1 drives the transmission belt 20 to rotate, thereby completing the sand and gravel transport. When the friction between the transmission belt 20 and the roller 1 becomes insufficient after long-term use, in order to continue working, the air pump 5 blows air, which is then transported to the push air bag 4 through the rotating joint 6 and the air supply pipe 7. This causes the push air bag 4 to inflate, thereby pushing multiple support plates 9 to move. These plates then push multiple support blocks 11 and ceramic patches 12 to move along multiple sliding grooves 8, allowing the ceramic patches 12 to extend outside the roller 1. The multiple ceramic patches 12 and support blocks 11 can temporarily increase the friction between the roller 1 and the transmission belt 20, allowing the sand making machine conveyor to continue operating and avoiding any impact on the sand and gravel transport. After the sand making machine stops working, the roller 1 is then replaced and repaired.

[0040] Compared with related technologies, the conveyor belt roller of the sand making machine provided by the present invention has the following beneficial effects:

[0041] The air pump 5, rotary joint 6, air supply pipe 7, and push air bag 4 can be used as power to move multiple support plates 9, multiple support blocks 11, and multiple ceramic patches 12 respectively. The tension of the transmission belt 20 can be adjusted by the multiple support blocks 11, and the ceramic patches 12 can indirectly increase the friction between the drum 1 and the transmission belt 20. This provides temporary friction between the drum 1 and the transmission belt 20, thereby ensuring the normal operation of the sand making machine and the normal progress of the work.

[0042] Second embodiment:

[0043] Based on the sand making machine conveyor belt roller provided in the first embodiment of this application, the second embodiment of this application proposes another sand making machine conveyor belt roller. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0044] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0045] Please refer to the following: Figures 5-7 The sand making machine conveyor belt roller also includes a storage cavity 14, which is opened on the support block 11. A friction airbag 17 is installed in the storage cavity 14. When the friction airbag 17 is in the storage cavity 14, it is in a contracted state. T-shaped through grooves 15 are opened on both outer walls of the support block 11. The friction airbag 17 can extend out of the support block 11 through the T-shaped through grooves 15. An air supply pipe 2 18 is connected to one outer wall of the friction airbag 17. The other end of the air supply pipe 2 18 is connected to the push airbag 4.

[0046] Sealing foil 16 is pasted on one inner wall of each of the two T-shaped through grooves 15. The outer walls of the two sealing foils 16 that are close to each other are pasted to the outer wall of the friction airbag 17. The sealing foil 16 can prevent the friction airbag 17 from contacting the outside world, thus improving the protection of the friction airbag 17. The sealing foil 16 and the T-shaped through groove 15 can be pasted with double-sided tape, while the sealing foil 16 and the friction airbag 17 can be connected with 502 glue, which has a high adhesive strength.

[0047] A one-way valve 19 is installed on the second air supply pipe 18, with its air inlet facing the push airbag 4. The one-way valve 19 can prevent the pressure from decreasing during the contact between the friction airbag 17 and the transmission belt 20, thus ensuring the contact surface between the friction airbag 17 and the transmission belt 20.

[0048] The friction airbag 17 is made of rubber and has grooves engraved on its surface to increase the friction between it and the drive belt 20.

[0049] In this embodiment:

[0050] When the friction between the drive belt 20 and the roller 1 is increased by the ceramic patch 12, the air pressure in the push airbag 4 can be further increased by the air pump 5. As the air pressure in the push airbag 4 increases, the airflow will be delivered to the friction airbag 17 through the air supply pipe 18. After the pressure in the friction airbag 17 increases, it will extend to the outside of the support block 11 through the two T-shaped through slots 15, thereby sealing the gap between the roller 1 and the drive belt 20 and preventing sand and gravel from entering the gap between the roller 1 and the drive belt 20. At the same time, by setting the friction airbag 17, the friction area between the roller 1 and the drive belt 20 can be indirectly increased, thereby ensuring the friction effect of the roller 1 on the drive belt 20.

[0051] Third embodiment:

[0052] Based on the sand making machine conveyor belt roller provided in the first embodiment of this application, the third embodiment of this application proposes another sand making machine conveyor belt roller. The third embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the third embodiment will not affect the separate implementation of the first embodiment.

[0053] The third embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0054] Please refer to the following: Figures 8-10 The sand making machine conveyor belt roller also includes two fixed frames 21, which are respectively fixedly installed on one side of the outer wall of the two support frames 3. A cleaning roller 24 is rotatably installed on the outer wall of the two support frames 3 that are close to each other. A brush is installed on the surface of the cleaning roller 24, and the brush contacts one side of the outer wall of the transmission belt 20. A collection frame 28 is fixedly installed on the two support frames 3. The collection frame 28 is located below the cleaning roller 24. The cleaning roller 24 is connected to the roller 1 through a transmission mechanism.

[0055] The transmission mechanism includes: a transmission rod 22, a first transmission gear 23, a second transmission gear 25, and two rotating belts 27. The transmission rod 22 is rotatably mounted on the outer wall of two fixed frames 21 on one side close to each other. The first transmission gear 23 is fixedly sleeved on the transmission rod 22, and the second transmission gear 25 is fixedly sleeved on the cleaning roller 24. An annular groove is provided on the outer wall of the cleaning roller 24, and the second transmission gear 25 is fixedly sleeved on the inner wall of the annular groove. The outer teeth of the second transmission gear 25 must be located in the annular groove to avoid damaging the surface of the transmission belt 20. The second transmission gear 25 meshes with the first transmission gear 23. Both rotating belts 27 are sleeved on the roller 1 and the transmission rod 22. There are two annular grooves 26 on the outer wall of the roller 1, and the two rotating belts 27 are respectively sleeved in the two annular grooves 26. The outer walls of the two rotating belts 27 are lower than the outer wall of the roller 1 to avoid affecting the connection between the roller 1 and the transmission belt 20. Two belt sleeves are sleeved on the transmission rod 22, and the two rotating belts 27 are respectively sleeved on the outer walls of the two belt sleeves.

[0056] A discharge frame 29 is fixedly installed on one outer wall of the collection frame 28. The discharge frame 29 is connected to the collection frame 28. A discharge pipe 30 is fixedly installed at the bottom of the discharge frame 29. The bottom inner wall of the collection frame 28 is set as a first inclined surface, and the bottom inner wall of the discharge frame 29 is set as a second inclined surface. There is a conical groove on the bottom inner wall of the discharge frame 29. The bottom end of the conical groove is connected to the discharge pipe 30. Through the setting of the first inclined surface, the second inclined surface and the conical groove, it is convenient for sand and gravel to roll into the discharge pipe 30 and be discharged through the discharge pipe 30 after falling into the collection frame 28.

[0057] In this embodiment:

[0058] When the drum 1 rotates, the two rotating belts 27 drive the transmission rod 22 to rotate, which in turn drives the transmission gear 23 to rotate. Driven by the transmission gear 23, the transmission gear 25 drives the cleaning roller 24 to rotate. The cleaning roller 24 can clean the surface of the transmission belt that is about to come into contact with the surface of the drum 1, so as to prevent sand and gravel from adhering to the surface of the transmission belt and causing damage to the transmission belt 20 when it comes into contact with the surface of the drum 1, thus improving the protection effect of the transmission belt 20. The cleaned sand and gravel will fall into the collection frame 28 and roll on the bottom inner wall of the collection frame 28 into the discharge frame 29, and then be discharged through the discharge pipe 30.

[0059] Fourth embodiment:

[0060] Based on the sand making machine conveyor belt roller provided in the first embodiment of this application, the fourth embodiment of this application proposes another sand making machine conveyor belt roller. The fourth embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the fourth embodiment will not affect the separate implementation of the first embodiment.

[0061] The fourth embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0062] Please refer to the following: Figures 11-12 The conveyor belt roller of the sand making machine also includes a suction fan 31. The suction fan 31 is fixedly installed on the outer wall of the fixed frame 21 near the material feeding frame 29. An air suction frame 32 is provided on the outer wall of the material feeding frame 29. An air supply pipe 33 is fixedly installed on the air inlet of the suction fan 31. The other end of the air supply pipe 33 is connected to the air suction frame 32. An air supply channel 34 is provided on the inner wall of the material feeding frame 29. The air supply channel 34 is connected to the air suction frame 32. A filter plate 35 is provided in the air supply channel 34.

[0063] The filter plate 35 is set at an angle, and the bottom of the air passage 34 is provided with a third inclined surface. By setting the filter plate 35 at an angle, the filtered impurities can be easily removed from the filter plate 35 under the action of weight, thus avoiding clogging of the filter plate 35.

[0064] In this embodiment:

[0065] When cleaning dust through the cleaning roller 24, the suction fan 31 can be started. Under the action of the air supply pipe 33, the sand and dust cleaned by the cleaning roller 24 are sucked into the discharge frame 29. Under the action of the filter plate 35, the dust is filtered, and the filtered sand and dust will continue to be discharged from the discharge frame 29 through the discharge pipe 30, thereby improving the cleaning effect on the transmission belt 20.

[0066] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
