Description

Technical Field

[0001] The present invention relates to the technical field of suspension conveying, and specifically relates to a multi-power heat-sealing cover belt conveying mechanism. Background Technique

[0002] A heat-sealing cover belt is a sealing belt made of materials such as polyamide, polyester, and polypropylene; different materials have different characteristics and uses, but they can all melt at high temperatures and form a firm seal with the surface of the packaging bag; during the production process, the raw materials of the heat-sealing cover belt need to be transported into the production workshop, and after production, the heat-sealing cover belt needs to be transported to the storage place. At this time, a belt conveyor needs to be used to transport it;

[0003] A belt conveying mechanism is a machine that uses friction drive to continuously transport materials; the belt conveying mechanism can form a material conveying process for materials on a certain conveying line from the initial feeding point to the final discharging point. It can convey both fragmented materials and packaged materials; in addition to pure material conveying, it can also cooperate with the requirements of the technological processes in the production processes of various industrial enterprises to form a rhythmic flow production line; during the conveying process, if extremely heavy materials are encountered, they can be suspended and cooperate with the belt conveying mechanism to bear the weight of the materials together, and thus form a suspension conveying system;

[0004] Considering the need for different conveying distances during conveying, existing equipment needs to splice multiple conveying equipment for long-distance conveying, and needs to customize corresponding sizes for short-distance conveying, and cannot be applied to different scenarios; considering the conveying of heavier materials, due to the relatively long wheelbase between the support shafts of the conveyor belt, the conveyor belt may be bent and may collide with the support shafts, which may reduce the service life of the equipment.

[0008] A suspension unit is arranged on the outer side of the support frame. The suspension unit is fixed to the ground and is used for suspending materials. On the side where every two support frames are close to each other, a support block is fixedly connected. On the side of the support frame far from the drive shaft, a support unit is fixedly connected. On the side where the support units are close to each other, a plurality of adjustment units are fixedly connected. The adjustment units are connected to each other and are fixedly connected to the support block.

[0009] The adjustment unit includes two first spline shafts. The first spline shafts are fixedly connected to the support block. The inner surfaces of the first spline shafts are slidably connected with second spline shafts. On the side where the first spline shafts are close to each other, a first fixed shaft is fixedly connected. Two first connecting rods are rotatably connected to the first fixed shaft. On the side where the second spline shafts are close to each other, a second fixed shaft is fixedly connected. Two second connecting rods are rotatably connected to the second fixed shaft. Rotation holes are formed at the ends of the first connecting rod and the second connecting rod close to the top, and support shafts are rotatably connected in the rotation holes.

[0010] Further, adjustment holes are formed in the middle of the first connecting rod and the second connecting rod, and a relaxation unit is rotatably connected in the adjustment holes. On the side of one support frame close to the relaxation unit, a first telescopic rod is fixedly connected, and the first telescopic rod is fixedly connected to the relaxation unit.

[0011] Further, the relaxation unit includes an adjustment block. Sliding holes are symmetrically formed on the surface of the adjustment block. Sliding shafts are slidably connected in the sliding holes. A relaxation block is fixedly connected to the bottom of the sliding shaft. A plurality of second springs are fixedly connected between the relaxation block and the adjustment block. A relaxation shaft is rotatably connected to the middle of the relaxation block, and the relaxation shaft is in contact with the conveyor belt.

[0012] Further, the support unit includes a plurality of triangular brackets. Connection blocks are fixedly connected to the tops of the triangular brackets. A support plate is fixedly connected to the tops of every two connection blocks. A sliding groove is formed on the surface of the support plate. A fixed frame is slidably connected in the sliding groove. An inclined shaft is rotatably connected to one side of the fixed frame.

[0013] Further, an auxiliary driving block is fixedly connected to the side of the triangular bracket close to the adjustment unit. An auxiliary driving motor is arranged inside the auxiliary driving block. An auxiliary driving shaft is fixedly connected to the output end of the auxiliary driving motor, and the auxiliary driving shaft is in contact with the conveyor belt.

[0014] Further, fixing holes are formed on both sides of the triangular bracket, and second telescopic rods are fixedly connected to the fixing holes.

[0015] Further, a first spring is fixedly connected between every two auxiliary driving blocks.

[0016] Furthermore, moving units are fixedly connected to the bottoms of the triangular brackets. The moving unit includes a fixed block, which is fixedly connected to the triangular bracket.

[0017] The present invention has the following beneficial effects:

[0018] 1. The present invention can adjust the conveying distance of the conveyor belt by adjusting the first connecting rod and the second connecting rod, and can be adapted to different scenarios. When adjusting the first connecting rod and the second connecting rod, it will drive the movement of the support shaft at the same time and adjust the height of the support shaft. When the conveying distance increases, the height of the support shaft will decrease. Thus, the conveyor belt can be made long and deep and can be used to convey a large amount of light materials. The suspension unit can suspend the materials, place the materials on the conveyor belt, and the conveyor belt distributes the gravity of the materials, thereby reducing the gravity of the materials borne by the suspension unit.

[0019] 2. When the present invention needs to convey a large amount of raw materials, resulting in heavy weight, by adjusting the first connecting rod and the second connecting rod and shortening the conveying distance of the conveyor belt, at this time, the first connecting rod and the second connecting rod will contract and drive the support shafts to approach each other. When the support shafts approach each other, the wheelbase will be shortened, and better support can be obtained when conveying more and heavier materials, thus avoiding the situation where the conveyor belt is bent.

[0020] 3. When the present invention conveys heavier materials or a longer conveying distance, by starting the auxiliary motor in the auxiliary block, at this time, the auxiliary motor will drive the auxiliary shaft to rotate. Since the auxiliary shaft is in contact with the conveyor belt, when the auxiliary shaft rotates, it will drive the conveyor belt to transmit power, and additional power can be provided to the conveyor belt, thereby adapting to the situation of conveying more and heavier materials or a longer conveying distance. When the conveyor belt extends and contracts, through the setting of the tensioning unit, the conveyor belt can always be kept tight, so that the auxiliary shaft and the conveyor belt can always be in contact, and the transmission efficiency and effect of power can be improved.

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1 - 8 As shown, the present invention is a multi-power heat-sealing cover belt conveying mechanism, including four support frames 11. A driving motor 12 is fixedly connected to the inner surface of the support frame 11. A driving shaft 13 is rotatably connected to one side of every two adjacent support frames 11. The output shaft of the driving motor 12 is drivingly connected to a transmission belt 14, and the transmission belt 14 is drivingly connected to the driving shaft 13. A conveyor belt 1 is drivingly connected to the outer surface of the driving shaft 13;

[0035] A suspension unit 6 is arranged outside the support frame 6. The suspension unit 6 is fixed to the ground and is used for suspending materials; A support block 111 is fixedly connected to one side of every two adjacent support frames 11. Support units 2 are fixedly connected to the sides of the support frames 11 away from the driving shaft 13; A plurality of adjusting units 3 are fixedly connected to the sides of the support units 2 close to each other; The adjusting units 3 are connected to each other, and the adjusting units 3 are fixedly connected to the support block 111;

[0036] The adjusting unit 3 includes two first spline shafts 31. The first spline shafts 31 are fixedly connected to the support block 111. Second spline shafts 32 are slidably connected to the inner surfaces of the first spline shafts 31. A first fixed shaft 34 is fixedly connected to one side of the first spline shafts 31 close to each other. Two first connecting rods 311 are rotatably connected to the first fixed shaft 34; A second fixed shaft 341 is fixedly connected to one side of the second spline shafts 32 close to each other. Two second connecting rods 321 are rotatably connected to the second fixed shaft 341. Rotation holes are formed at the ends of the first connecting rods 311 and the second connecting rods 321 close to the top, and support shafts 33 are rotatably connected in the rotation holes.

[0037] In this embodiment, considering the need for different conveying distances during conveying, existing equipment needs to be spliced with multiple conveying devices for long-distance conveying, and corresponding sizes need to be customized for short-distance conveying, which cannot be applied to different scenarios; Considering that when conveying heavy materials, due to the relatively large distance between the support shafts 33 of the conveyor belt 1, the conveyor belt 1 may be bent and may collide with the support shafts 33, which may reduce the service life of the equipment;

[0038] When using the device, start the drive motor 12, and the conveyor belt 14 transmits power to the drive shaft 13. When the drive shaft 13 rotates, it drives the conveyor belt 1 to convey materials. At this time, the materials can be conveyed. When a longer conveying distance is required, the angles of the first connecting rod 311 and the second connecting rod 321 can be adjusted. Thus, the first connecting rod 311 and the second connecting rod 321 can drive the first spline shaft 31 and the second spline shaft 32 to move, and the first spline shaft 31 and the second spline shaft 32 can push the support frame 11 on the other side to move. When the support frame 11 moves, it drives the drive shaft 13 to move. Thereby, the conveying distance of the conveyor belt 1 can be increased, and the conveying distance of the conveyor belt 1 can be adjusted by adjusting the first connecting rod 311 and the second connecting rod 321 to adapt to different scenarios. When adjusting the first connecting rod 311 and the second connecting rod 321, it will simultaneously drive the movement of the support shaft 33 and adjust the height of the support shaft 33. When the conveying distance increases, the height of the support shaft 33 will decrease. Thus, the conveyor belt 1 can become long and deep and can be used to convey a large amount of light materials, such as when conveying the finished heat-sealed cover belt to the storage place;

[0039] When a large amount of raw materials need to be conveyed, resulting in a heavy weight, by adjusting the first connecting rod 311 and the second connecting rod 321 and shortening the conveying distance of the conveyor belt 1, at this time, the first connecting rod 311 and the second connecting rod 321 will contract and drive the support shafts 33 to approach each other. When the support shafts 33 approach each other, the wheelbase will be shortened, and better support can be obtained when conveying heavier materials, such as when conveying a large amount of raw materials, thereby avoiding the situation where the conveyor belt 1 is bent under pressure;

[0040] When conveying extremely heavy items, the conveyor belt 1 may not be able to bear the pressure of the materials. At this time, the suspension unit 6 can suspend the materials, and at the same time, the materials can be placed on the conveyor belt 1. At this time, not only can the materials be conveyed through the conveyor belt 1, but also the gravity of the materials can be shared by the conveyor belt 1. Thus, the gravity of the materials borne by the suspension unit 6 can be reduced, and the service life of the device can be increased.

[0041] Specifically, adjustment holes are provided in the middle of the first connecting rod 311 and the second connecting rod 321, and a relaxation unit 4 is rotatably connected in the adjustment holes; on one side of a support frame 11 close to the relaxation unit 4, a first telescopic rod 112 is fixedly connected, and the first telescopic rod 112 is fixedly connected to the relaxation unit 4.

[0042] In this embodiment, considering that when adjusting the first connecting rod 311 and the second connecting rod 321, uneven fluctuations may occur during the adjustment, resulting in uneven heights of the support shafts 33 and causing undulations on the surface of the conveyor belt 1, which may affect the conveying efficiency. Seriously, it may cause the conveyed materials to fall or be unable to be conveyed;

[0043] By providing the first telescopic rod 112, when it is necessary to adjust the first connecting rod 311 and the second connecting rod 321, the tensioning unit 4 is pushed to move. Since the tensioning unit 4 is located in the middle of the first connecting rod 311 and the second connecting rod 321, when the tensioning unit 4 moves, it will drive the extension and contraction of the first connecting rod 311 and the second connecting rod 321. And through the interconnection between the adjusting units 3, all the first connecting rods 311 and the second connecting rods 321 can be adjusted synchronously. By using the first telescopic rod 112, not only can the manpower required for manual adjustment be reduced, but also the possibility of errors in adjusting the first connecting rod 311 and the second connecting rod 321 can be reduced. Thus, the service life of the equipment can be increased, and the adjustment efficiency can also be increased.

[0044] Specifically, the tensioning unit 4 includes an adjusting block 41. Symmetric sliding holes 411 are formed on the surface of the adjusting block 41. A sliding shaft 42 is slidably connected in the sliding holes 411. The bottom of the sliding shaft 42 is fixedly connected with a tensioning block 43. A plurality of second springs 45 are fixedly connected between the tensioning block 43 and the adjusting block 41. A tensioning shaft 44 is rotatably connected to the middle of the tensioning block 43. The tensioning shaft 44 contacts the conveyor belt 1.

[0045] In this embodiment, considering that the length of the conveyor belt 1 will change when the conveyor belt 1 extends and contracts, enough redundancy needs to be reserved for the conveyor belt 1 before use for its extension. When the conveyor belt 1 contracts, part of the conveyor belt 1 will lose support, and winding or overlapping may occur.

[0046] By providing the tensioning shaft 44 and the tensioning block 43, when the conveyor belt 1 extends and contracts, the tensioning shaft 44 and the tensioning block 43 can be adjusted under the action of the second springs 45, and the sliding shaft 42 can slide in the sliding holes 411. When the conveyor belt 1 extends, the tensioning shaft 44 and the tensioning block 43 contract inward and compress the second springs 45. When the conveyor belt 1 contracts, the tensioning shaft 44 and the tensioning block 43 will move outward under the resilience of the second springs 45, and keep the conveyor belt 1 taut. Thus, it can prevent the conveyor belt 1 from losing support and reduce the occurrence of winding or overlapping.

[0047] Specifically, the support unit 2 includes a plurality of triangular brackets 21. Connecting blocks 24 are fixedly connected to the tops of the triangular brackets 21. A support plate 26 is fixedly connected to the tops of every two connecting blocks 24. A sliding groove is formed on the surface of the support plate 26. A fixing frame 16 is slidably connected in the sliding groove. An inclined shaft 161 is rotatably connected to one side of the fixing frame 16.

[0048] In this embodiment, the triangular support 21 is provided to make the support of the equipment more stable. Compared with the existing equipment, it has a larger contact area with the ground and better stability, and can maintain good support when transporting heavier materials. The support plate 26 is provided to be connected to the first spline shaft 31 and the second spline shaft 32. When the first spline shaft 31 and the second spline shaft 32 move, the triangular support 21 can be driven to move synchronously. Thus, when the conveyor belt 1 extends and contracts, the triangular support 21 can be driven to move synchronously, so that the triangular support 21 can provide better support for the adjusting unit 3.

[0049] Specifically, a secondary driving block is fixedly connected to the side of the triangular support 21 close to the adjusting unit 3. A secondary driving motor is arranged inside the secondary driving block. The output end of the secondary driving motor is fixedly connected to a secondary driving shaft 25, and the secondary driving shaft 25 is in contact with the conveyor belt 1.

[0050] In this embodiment, considering that the conveyor belt 1 is relatively long and only the driving motors 12 at both ends of the conveyor belt 1 provide power during transportation, when transporting a large amount or heavy materials, the conveying speed may be slow or the conveying may not be possible due to insufficient power, which will affect the conveying efficiency.

[0051] When transporting heavy materials or over a long distance, by starting the secondary driving motor in the secondary driving block, the secondary driving motor will drive the secondary driving shaft 25 to rotate at this time. Since the secondary driving shaft 25 is in contact with the conveyor belt 1, the conveyor belt 1 will be driven to transmit power when the secondary driving shaft 25 rotates, and additional power can be provided for the conveyor belt 1. Thus, it can adapt to the situation of transporting more and heavier materials or over a longer distance. When the conveyor belt 1 extends and contracts, through the setting of the tensioning unit 4, the conveyor belt 1 can always be kept taut, so that the secondary driving shaft 25 and the conveyor belt 1 can always be in contact, which can improve the transmission efficiency and effect of power.

[0052] Specifically, fixing holes 211 are formed on both sides of the triangular support 21, and second telescopic rods 22 are fixedly connected to the fixing holes 211.

[0053] In this embodiment, considering that the triangular support 21 will move when the conveyor belt 1 extends and contracts; through the setting of the second telescopic rod 22, auxiliary power can be provided when the triangular support 21 moves. Since the support plate 26 is connected to the first support shaft 33 and the second support shaft 33, when the second telescopic rod 22 pushes the triangular support 21 to move, the adjusting unit 3 can be driven to adjust synchronously. At the same time, when the adjusting unit 3 adjusts, the triangular support 21 can be adjusted synchronously, which can perform auxiliary adjustment when the power of the first telescopic rod 112 is insufficient. Since the adjusting unit 3 will push all the support units 2 when adjusting, through the setting of the second telescopic rod 22, the adjustment pressure of the adjusting unit 3 can also be shared.

[0054] Specifically, a first spring 23 is fixedly connected between every two of the auxiliary moving blocks.

[0055] In this embodiment, the arrangement of the first spring 23 can generate a rebound when the distance between the triangular brackets 21 is too close, which can prevent collisions between the support plates 26. At the same time, it can apply a pulling force when the distance between the triangular brackets 21 is too far. After the conveying is completed, the triangular brackets 21 can be contracted by the first spring 23, and the conveyor belt 1 can be contracted, so that the equipment is more convenient to store and can save storage space.

[0056] Specifically, moving units 5 are fixedly connected to the bottoms of the triangular brackets 21. Each moving unit 5 includes a fixed block 51, which is fixedly connected to the triangular bracket 21. A through groove is formed in the middle of the fixed block 51. Third telescopic rods 53 are fixedly connected to both sides of the top of the fixed block 51. The tops of the third telescopic rods 53 are fixedly connected to an adjusting plate 54. A fixing plate is fixedly connected to the bottom of the middle of the adjusting plate 54. A moving shaft 52 is rotatably connected to one end of the fixing plate away from the adjusting plate 54.

[0057] In this embodiment, considering that during the process of adjusting the length of the equipment, the triangular brackets 21 will rub against the ground, which may lead to greater power consumption for adjusting the length. After long-term use, the triangular brackets 21 may be excessively worn, and the heights of the triangular brackets 21 may be uneven, which may cause the conveyor belt 1 to tilt during use.

[0058] When the conveyor belt 1 is extended and contracted, due to the arrangement of the third telescopic rods 53, the third telescopic rods 53 will push the adjusting plate 54 to move. At this time, the adjusting plate 54 will slide in the through groove. When the adjusting plate 54 moves, it will drive the moving shaft 52 to move. When the moving shaft 52 contacts the ground, the sliding friction can be converted into rolling friction, thereby reducing the friction during the movement of the equipment, reducing power consumption, and avoiding friction damage to the triangular brackets 21.

[0059] During use,

[0060] First, when using the device, start the drive motor 12, and the conveyor belt 14 transmits power to the drive shaft 13. When the drive shaft 13 rotates, it drives the conveyor belt 1 to convey, and at this time, the material can be conveyed. When a longer conveying distance is required, the angles of the first connecting rod 311 and the second connecting rod 321 can be adjusted. Thus, the first connecting rod 311 and the second connecting rod 321 drive the first spline shaft 31 and the second spline shaft 32 to move, and the first spline shaft 31 and the second spline shaft 32 push the support frame 11 on the other side to move. When the support frame 11 moves, it drives the drive shaft 13 to move. Thus, the conveying distance of the conveyor belt 1 can be increased, and the conveying distance of the conveyor belt 1 can be adjusted by adjusting the first connecting rod 311 and the second connecting rod 321 to adapt to different scenarios. When adjusting the first connecting rod 311 and the second connecting rod 321, it will simultaneously drive the movement of the support shaft 33 and adjust the height of the support shaft 33. When the conveying distance increases, the height of the support shaft 33 will decrease. Thus, the conveyor belt 1 can become long and deep and can be used to convey a large amount of light materials, such as when conveying the finished heat-sealed cover belt to the storage place;

[0061] When a large amount of raw materials need to be conveyed, resulting in a heavier load, adjust the first connecting rod 311 and the second connecting rod 321 and shorten the conveying distance of the conveyor belt 1. At this time, the first connecting rod 311 and the second connecting rod 321 will contract and drive the support shafts 33 to approach each other. When the support shafts 33 approach each other, the wheelbase will be shortened, and better support can be obtained when conveying heavier materials, such as when conveying a large amount of raw materials, thus avoiding the situation where the conveyor belt 1 is bent;

[0062] Through the setting of the first telescopic rod 112, when it is necessary to adjust the first connecting rod 311 and the second connecting rod 321, it pushes the tensioning unit 4 to move. Since the tensioning unit 4 is located in the middle of the first connecting rod 311 and the second connecting rod 321, when the tensioning unit 4 moves, it drives the extension and contraction of the first connecting rod 311 and the second connecting rod 321. And through the interconnection between the adjusting units 3, all the first connecting rods 311 and the second connecting rods 321 can be adjusted synchronously. Through the first telescopic rod 112, not only can the manpower required for manual adjustment be reduced, but also the possibility of errors in adjusting the first connecting rod 311 and the second connecting rod 321 can be reduced. Thus, the service life of the device can be increased, and the adjustment efficiency can also be increased.

[0063] Secondly, through the settings of the relaxation shaft 44 and the relaxation block 43, when the conveyor belt 1 extends and contracts, the relaxation shaft 44 and the relaxation block 43 can be adjusted under the action of the second spring 45, and the sliding shaft 42 slides in the sliding hole 411. When the conveyor belt 1 extends, the relaxation shaft 44 and the relaxation block 43 contract inward and compress the second spring 45. When the conveyor belt 1 contracts, the relaxation shaft 44 and the relaxation block 43 will move outward under the resilience of the second spring 45, and keep the conveyor belt 1 taut. Thus, it can prevent the conveyor belt 1 from losing support and reduce the occurrence of entanglement or overlap;

[0064] When conveying a large amount of materials or over a long distance, by starting the auxiliary motor in the auxiliary block, the auxiliary motor will drive the auxiliary shaft 25 to rotate at this time. Since the auxiliary shaft 25 is in contact with the conveyor belt 1, the conveyor belt 1 will be driven to transmit when the auxiliary shaft 25 rotates, which can provide additional power for the conveyor belt 1. Thus, it can adapt to the situation of conveying more and heavier materials or over a longer distance; When the conveyor belt 1 extends and contracts, through the setting of the relaxation unit 4, the conveyor belt 1 can always be kept taut, so that the auxiliary shaft 25 and the conveyor belt 1 can always be in contact, which can improve the transmission efficiency and effect of power.

[0065] Finally, through the setting of the triangular support 21, it can be more stable when supporting the equipment, and has a larger contact area with the ground and better stability compared with the existing equipment. When transporting heavier materials, it can maintain good support. Through the setting of the support plate 26, it can be connected to the first spline shaft 31 and the second spline shaft 32. When the first spline shaft 31 and the second spline shaft 32 move, the triangular support 21 can be driven to move synchronously. Thus, when the conveyor belt 1 extends and contracts, the triangular support 21 can be driven to move synchronously, so that the triangular support 21 can provide better support for the adjustment unit 3;

[0066] Through the setting of the second telescopic rod 22, auxiliary power can be provided when the triangular support 21 moves. Since the support plate 26 is connected to the first support shaft 33 and the second support shaft 33, when the second telescopic rod 22 pushes the triangular support 21 to move, the adjustment unit 3 can be driven to adjust synchronously. At the same time, when the adjustment unit 3 adjusts, the triangular support 21 can be adjusted synchronously, which can provide auxiliary adjustment when the power of the first telescopic rod 112 is insufficient. Since the adjustment unit 3 will push all the support units 2 when adjusting, through the setting of the second telescopic rod 22, the adjustment pressure of the adjustment unit 3 can also be shared;

[0067] The arrangement of the first spring 23 can generate a resilient force when the triangular brackets 21 are too close, preventing collisions between the support plates 26. At the same time, it can apply a pulling force when the triangular brackets 21 are too far apart. After the conveying is completed, the triangular brackets 21 can be retracted by the first spring 23, enabling the conveyor belt 1 to be retracted, making the device more convenient for storage and saving storage space.

[0068] When the conveyor belt 1 extends and retracts, the arrangement of the third telescopic rod 53 causes the third telescopic rod 53 to push the adjusting plate 54 to move. At this time, the adjusting plate 54 slides in the through groove. When the adjusting plate 54 moves, it drives the moving shaft 52 to move. When the moving shaft 52 contacts the ground, the sliding friction can be converted into rolling friction, thereby reducing the friction during the movement of the device, reducing power consumption, and avoiding friction damage to the triangular brackets 21.
