Description

Technical Field

[0001] This invention relates to the field of overhead conveyor technology, specifically to a multi-powered heat-sealing belt conveyor mechanism. Background Technology

[0002] Heat-sealing tape is a sealing tape 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 strong seal with the surface of the packaging bag. During the production process, the raw materials for heat-sealing tape need to be transported to the production plant, and after production, the heat-sealing tape needs to be transported to the storage area. At this time, a belt conveyor is required to transport it.

[0003] A belt conveyor is a friction-driven machine that transports materials continuously. It can transport materials along a specific conveyor line from the initial feeding point to the final unloading point, handling both bulk and packaged materials. Besides simple material transport, it can also be integrated with the technological processes of various industrial enterprises to form rhythmic assembly line transport systems. In cases of extremely heavy materials, a suspension system can be used to support the weight of the materials, creating a suspended conveyor system.

[0004] Considering the varying conveying distances required, existing equipment necessitates the splicing of multiple conveying devices for longer distances, while custom-made sizes are needed for shorter distances, making it unsuitable for different scenarios. Furthermore, when conveying heavy materials, the large wheelbase between the support shafts of the conveyor belt may cause the belt to bend and potentially collide with the support shafts, reducing the equipment's lifespan. Summary of the Invention

[0008] A suspension unit is provided on the outer side of the support frame. The suspension unit is fixed to the ground and is used to suspend materials.

[0009] The adjustment unit includes two first splined shafts, which are fixedly connected to a support block. A second splined shaft is slidably connected to the inner surface of each first splined shaft. A first fixed shaft is fixedly connected to one side of each first splined shaft, and two first connecting rods are rotatably connected to the first fixed shaft. A second fixed shaft is fixedly connected to one side of each second splined shaft, and two second connecting rods are rotatably connected to the second fixed shaft. Rotating holes are provided at the top ends of both the first and second connecting rods, and support shafts are rotatably connected within these rotating holes.

[0010] Furthermore, an adjustment hole is provided in the middle of the first connecting rod and the second connecting rod, and a tensioning unit is rotatably connected in the adjustment hole; a first telescopic rod is fixedly connected to one side of the support frame near the tensioning unit, and the first telescopic rod is fixedly connected to the tensioning unit.

[0011] Furthermore, the tensioning unit includes an adjusting block, the surface of which is symmetrically provided with sliding holes, a sliding shaft is slidably connected in the sliding holes, a tensioning block is fixedly connected to the bottom of the sliding shaft, a plurality of second springs are fixedly connected between the tensioning block and the adjusting block, a tensioning shaft is rotatably connected to the middle of the tensioning block, and the tensioning shaft is in contact with the conveyor belt.

[0012] Furthermore, the support unit includes multiple triangular brackets, each of which has a connecting block fixedly connected to its top. A support plate is fixedly connected to the top of every two connecting blocks. A sliding groove is provided on the surface of the support plate, and a fixed frame is slidably connected in the sliding groove. An inclined shaft is rotatably connected to one side of the fixed frame.

[0013] Furthermore, an auxiliary block is fixedly connected to the side of the triangular bracket near the adjustment unit. An auxiliary motor is installed inside the auxiliary block. An auxiliary shaft is fixedly connected to the output end of the auxiliary motor. The auxiliary shaft is in contact with the conveyor belt.

[0014] Furthermore, fixing holes are provided on both sides of the triangular bracket, and a second telescopic rod is fixedly connected to each fixing hole.

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

[0016] Furthermore, each of the triangular supports is fixedly connected to a movable unit at its bottom. The movable unit includes a fixed block, which is fixedly connected to the triangular support. A through groove is provided in the middle of the fixed block.

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

[0018] 1. This invention allows for adjustment of the conveying distance of the conveyor belt by adjusting the first and second connecting rods, adapting to different scenarios. When the first and second connecting rods are adjusted, the support shaft moves simultaneously, and its height is adjusted. As the conveying distance increases, the height of the support shaft decreases, thus making the conveyor belt longer and deeper, suitable for conveying large quantities of lightweight materials. The suspension unit can suspend the materials, placing them on the conveyor belt and distributing the weight of the materials, thereby reducing the weight of the materials borne by the suspension unit.

[0019] 2. When a large amount of material needs to be conveyed, resulting in a heavy load, the present invention adjusts the first and second connecting rods and shortens the conveying distance of the conveyor belt. At this time, the first and second connecting rods will retract and drive the support shafts to move closer to each other. When the support shafts move closer to each other, the wheelbase will be shortened, and better support will be obtained when conveying a large amount of heavy material, thereby preventing the conveyor belt from being bent.

[0020] 3. When conveying heavier materials or over longer distances, this invention activates the auxiliary motor within the auxiliary block. This motor drives the auxiliary shaft to rotate. Since the auxiliary shaft is in contact with the conveyor belt, its rotation drives the conveyor belt, providing additional power. This adapts to conveying larger quantities of heavier materials or over longer distances. Furthermore, the tensioning unit ensures the conveyor belt remains taut during extension and retraction, maintaining constant contact between the auxiliary shaft and the conveyor belt, thus improving power transmission efficiency and effectiveness.

[0033] 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, and 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] Please see Figures 1-8 As shown, the present invention is a multi-power heat-sealing cap conveyor mechanism, including four support frames 11. A drive motor 12 is fixedly connected to the inner surface of the support frame 11. A drive shaft 13 is rotatably connected to the side of each pair of support frames 11 that are close to each other. A transmission belt 14 is driven to the output shaft of the drive motor 12. The transmission belt 14 is driven to the drive shaft 13. A conveyor belt 1 is driven to the outer surface of the drive shaft 13.

[0035] A suspension unit 6 is provided on the outer side of the support frame 6. The suspension unit 6 is fixed to the ground and is used to suspend materials. A support block 111 is fixedly connected to the side of each pair of support frames 11 that are close to each other. A support unit 2 is fixedly connected to the side of each support frame 11 that is away from the drive shaft 13. Multiple adjustment units 3 are fixedly connected to the side of each support unit 2 that is close to each other. The adjustment units 3 are interconnected and fixedly connected to the support block 111.

[0036] The adjustment unit 3 includes two first spline shafts 31, which are fixedly connected to the support block 111. The inner surfaces of the first spline shafts 31 are slidably connected to second spline shafts 32. A first fixed shaft 34 is fixedly connected to one side of the first spline shafts 31 that is close to each other. The first fixed shaft 34 is rotatably connected to two first connecting rods 311. A second fixed shaft 341 is fixedly connected to one side of the second spline shafts 32 that is close to each other. The second fixed shaft 341 is rotatably connected to two second connecting rods 321. Rotating holes are provided at the top ends of the first connecting rods 311 and the second connecting rods 321. A support shaft 33 is rotatably connected in each of the rotating holes.

[0037] In this embodiment, considering that there may be different conveying distance requirements during conveying, the existing equipment requires splicing multiple conveying devices when conveying over a longer distance, and requires custom-made sizes when conveying over a shorter distance, which cannot be applied to different scenarios; considering that when conveying heavy materials, the large wheelbase between the support shafts 33 of the conveyor belt 1 may cause the conveyor belt 1 to be bent and may collide with the support shafts 33, which may reduce the service life of the equipment.

[0038] When using the equipment, the drive motor 12 is started, and the transmission belt 14 transmits power to the drive shaft 13. When the drive shaft 13 rotates, it drives the conveyor belt 1 to perform transmission, thus conveying materials. When a longer conveying distance is required, the angles of the first connecting rod 311 and the second connecting rod 321 can be adjusted. This allows the first connecting rod 311 and the second connecting rod 321 to 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 to push the support frame 11 on the other side to move. When moving, it will drive the drive shaft 13 to move, thereby increasing the conveying distance of the conveyor belt 1. The conveying distance of the conveyor belt 1 can be adjusted by adjusting the first link 311 and the second link 321, which can be adapted to different scenarios. When adjusting the first link 311 and the second link 321, it will simultaneously drive the support shaft 33 to move and adjust the height of the support shaft 33. When the conveying distance increases, the height of the support shaft 33 will be reduced, thereby making the conveyor belt 1 longer and deeper, which can be used to transport large quantities of light materials, such as when transporting the heat-sealed cover belt of the finished product to the storage area.

[0039] When a large amount of raw material needs to be conveyed, resulting in a heavy load, the first connecting rod 311 and the second connecting rod 321 are adjusted, and the conveying distance of the conveyor belt 1 is shortened. At this time, the first connecting rod 311 and the second connecting rod 321 will retract and drive the support shaft 33 to move closer to each other. When the support shaft 33 moves closer to each other, the wheelbase will be shortened, and better support will be obtained when conveying heavier materials, such as when conveying a large amount of raw materials, thereby preventing the conveyor belt 1 from being bent.

[0040] When conveying extremely heavy items, the conveyor belt 1 may not be able to withstand the pressure of the material. In this case, the suspension unit 6 can suspend the material and place it on the conveyor belt 1. At the same time, the material can not only be conveyed by the conveyor belt 1, but the weight of the material can also be distributed by the conveyor belt 1. This can reduce the weight of the material borne by the suspension unit 6 and increase the service life of the equipment.

[0041] Specifically, an adjustment hole is provided in the middle of the first connecting rod 311 and the second connecting rod 321, and a tensioning unit 4 is rotatably connected in the adjustment hole; a first telescopic rod 112 is fixedly connected to one of the support frames 11 near the tensioning unit 4, and the first telescopic rod 112 is fixedly connected to the tensioning unit 4.

[0042] In this embodiment, it is considered that when adjusting the first link 311 and the second link 321, uneven fluctuations may occur during the adjustment, resulting in uneven height of the support shaft 33 and uneven surface of the conveyor belt 1, which may affect the conveying efficiency. In severe cases, it may cause the conveyed material to fall off or become unable to be conveyed.

[0043] By setting the first telescopic rod 112, the tension unit 4 is moved when the first link 311 and the second link 321 need to be adjusted. Since the tension unit 4 is located in the middle of the first link 311 and the second link 321, the movement of the tension unit 4 will drive the extension and contraction of the first link 311 and the second link 321. Through the interconnection between the adjustment units 3, all the first links 311 and the second link 321 can be adjusted synchronously. The first telescopic rod 112 can not only reduce the manpower required for manual adjustment, but also reduce the possibility of errors in adjusting the first link 311 and the second link 321, thereby increasing the service life of the equipment and increasing the adjustment efficiency.

[0044] Specifically, the tension / relaxation unit 4 includes an adjusting block 41. The surface of the adjusting block 41 is symmetrically provided with sliding holes 411. A sliding shaft 42 is slidably connected in the sliding holes 411. A tension / relaxation block 43 is fixedly connected to the bottom of the sliding shaft 42. A plurality of second springs 45 are fixedly connected between the tension / relaxation block 43 and the adjusting block 41. A tension / relaxation shaft 44 is rotatably connected to the middle of the tension / relaxation block 43. The tension / relaxation shaft 44 is in contact with the conveyor belt 1.

[0045] In this embodiment, considering that the length of the conveyor belt 1 will change when it extends and retracts, it is necessary to reserve enough redundancy for the extension of the conveyor belt 1 before use. When the conveyor belt 1 retracts, it will cause part of the conveyor belt 1 to lose support, and may cause entanglement or overlap.

[0046] By setting up the tension shaft 44 and tension block 43, the tension shaft 44 and tension block 43 can be adjusted under the action of the second spring 45 when the conveyor belt 1 extends and retracts, and the sliding shaft 42 slides in the sliding hole 411. When the conveyor belt 1 extends, the tension shaft 44 and tension block 43 retract inward and compress the second spring 45. When the conveyor belt 1 retracts, the tension shaft 44 and tension block 43 will move outward under the rebound force of the second spring 45 and keep the conveyor belt 1 taut. This can prevent the conveyor belt 1 from losing support and reduce the occurrence of entanglement or overlap.

[0047] Specifically, the support unit 2 includes multiple triangular brackets 21, each of which is fixedly connected to a connecting block 24. A support plate 26 is fixedly connected to the top of every two connecting blocks 24. A sliding groove is provided on the surface of the support plate 26, and a fixed frame 16 is slidably connected in the sliding groove. An inclined shaft 161 is rotatably connected to one side of the fixed frame 16.

[0048] In this embodiment, the triangular bracket 21 provides greater stability when supporting the equipment, offering a larger contact area and stability compared to existing equipment. It maintains good support when transporting heavy materials. The support plate 26 connects to the first spline shaft 31 and the second spline shaft 32, allowing the triangular bracket 21 to move synchronously when the first spline shaft 31 and the second spline shaft 32 move. This enables the triangular bracket 21 to move synchronously when the conveyor belt 1 extends and retracts, thus providing better support for the adjustment unit 3.

[0049] Specifically, an auxiliary block is fixedly connected to the side of the triangular bracket 21 near the adjustment unit 3. An auxiliary motor is installed inside the auxiliary block. An auxiliary shaft 25 is fixedly connected to the output end of the auxiliary motor. The auxiliary shaft 25 is in contact with the conveyor belt 1.

[0050] In this embodiment, considering that the conveyor belt 1 is relatively long, the power is only provided by the drive motors 12 at both ends of the conveyor belt 1 during the conveying process. When transporting a large amount or heavy materials, the conveying speed may be slow or the materials may not be able to be conveyed due to insufficient power, which will affect the conveying efficiency.

[0051] When conveying heavier materials or over longer distances, the auxiliary motor inside the auxiliary block is activated. This motor drives the auxiliary shaft 25 to rotate. Since the auxiliary shaft 25 is in contact with the conveyor belt 1, its rotation drives the conveyor belt 1, providing additional power to the conveyor belt 1. This adapts to situations involving conveying larger quantities of heavier materials or over longer distances. When the conveyor belt 1 extends and retracts, the tensioning unit 4 keeps the conveyor belt 1 taut at all times, ensuring that the auxiliary shaft 25 remains in contact with the conveyor belt 1, thus improving the efficiency and effectiveness of power transmission.

[0052] Specifically, the triangular bracket 21 has fixing holes 211 on both sides, and the fixing holes 211 are fixedly connected to the second telescopic rod 22.

[0053] In this embodiment, considering that the triangular support 21 will move along with the conveyor belt 1 when it extends and retracts, the second telescopic rod 22 can provide auxiliary power 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, the second telescopic rod 22 can drive the adjustment unit 3 to adjust when it pushes the triangular support 21 to move. At the same time, the triangular support 21 can be adjusted simultaneously when the adjustment unit 3 is adjusted. It can also provide auxiliary adjustment when the first telescopic rod 112 is not powerful enough. Since the adjustment unit 3 will push all the support units 2 when it is adjusting, the second telescopic rod 22 can also share the adjustment pressure of the adjustment unit 3.

[0054] Specifically, a first spring 23 is fixedly connected between each pair of auxiliary blocks.

[0055] In this embodiment, the first spring 23 can generate a rebound when the triangular bracket 21 is too close, which can prevent collisions between the support plates 26. At the same time, it can apply a pull-back force when the triangular bracket 21 is too far apart. After the conveying is completed, the first spring 23 can retract the triangular bracket 21, which can retract the conveyor belt 1, thereby making the equipment easier to store and saving storage space.

[0056] Specifically, each of the triangular brackets 21 has a fixedly connected movable unit 5 at its bottom. The movable unit 5 includes a fixed block 51, which is fixedly connected to the triangular bracket 21. A through groove is provided in the middle of the fixed block 51. A third telescopic rod 53 is fixedly connected to both sides of the top of the fixed block 51. An adjusting plate 54 is fixedly connected to the top of the third telescopic rod 53. A fixed plate is fixedly connected to the bottom of the middle part of the adjusting plate 54. A movable shaft 52 is rotatably connected to the end of the fixed plate away from the adjusting plate 54.

[0057] In this embodiment, considering that the triangular bracket 21 will rub against the ground during the length adjustment process, it may result in greater power consumption for length adjustment. After long-term use, the triangular bracket 21 may be excessively worn, resulting in uneven height of the triangular bracket 21, which may cause the conveyor belt 1 to tilt during use.

[0058] When the conveyor belt 1 extends and retracts, the third telescopic rod 53 is set up so that it pushes 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, it can convert sliding friction into rolling friction, thereby reducing the friction during the movement of the equipment, reducing power consumption, and avoiding friction damage to the triangular bracket 21.

[0059] When using,

[0060] First, when using the equipment, the drive motor 12 is started, and the transmission belt 14 transmits power to the drive shaft 13. When the drive shaft 13 rotates, it drives the conveyor belt 1 to perform transmission, thus conveying materials. When a longer conveying distance is required, the angles of the first connecting rod 311 and the second connecting rod 321 can be adjusted. This allows the first connecting rod 311 and the second connecting rod 321 to 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 to push the support frame 11 on the other side to move. When the conveyor belt moves, it will drive the drive shaft 13 to move, thereby increasing the conveying distance of the conveyor belt 1. The conveying distance of the conveyor belt 1 can be adjusted by adjusting the first link 311 and the second link 321, which can be adapted to different scenarios. When adjusting the first link 311 and the second link 321, the support shaft 33 will move simultaneously, and the height of the support shaft 33 will be adjusted. When the conveying distance increases, the height of the support shaft 33 will be reduced, thereby making the conveyor belt 1 longer and deeper, which can be used to transport a large amount of light materials, such as when transporting the heat-sealed cover belt of the finished product to the storage area.

[0061] When a large amount of raw material needs to be conveyed, resulting in a heavy load, the first connecting rod 311 and the second connecting rod 321 are adjusted, and the conveying distance of the conveyor belt 1 is shortened. At this time, the first connecting rod 311 and the second connecting rod 321 will retract and drive the support shaft 33 to move closer to each other. When the support shaft 33 moves closer to each other, the wheelbase will be shortened, and better support will be obtained when conveying heavier materials, such as when conveying a large amount of raw materials, thereby preventing the conveyor belt 1 from being bent.

[0062] By setting the first telescopic rod 112, the tension unit 4 is moved when the first link 311 and the second link 321 need to be adjusted. Since the tension unit 4 is located in the middle of the first link 311 and the second link 321, the movement of the tension unit 4 will drive the extension and contraction of the first link 311 and the second link 321. Through the interconnection between the adjustment units 3, all the first links 311 and the second link 321 can be adjusted synchronously. The first telescopic rod 112 can not only reduce the manpower required for manual adjustment, but also reduce the possibility of errors in adjusting the first link 311 and the second link 321, thereby increasing the service life of the equipment and increasing the adjustment efficiency.

[0063] Secondly, by setting the tension shaft 44 and tension block 43, the tension shaft 44 and tension block 43 can be adjusted under the action of the second spring 45 when the conveyor belt 1 extends and retracts, and the sliding shaft 42 slides in the sliding hole 411. When the conveyor belt 1 extends, the tension shaft 44 and tension block 43 retract inward and compress the second spring 45. When the conveyor belt 1 retracts, the tension shaft 44 and tension block 43 will move outward under the rebound force of the second spring 45 and keep the conveyor belt 1 taut. This can prevent the conveyor belt 1 from losing support and reduce the occurrence of entanglement or overlap.

[0064] When conveying a large amount of material or a long conveying distance, the auxiliary motor inside the auxiliary block is started. At this time, the auxiliary motor will drive the auxiliary shaft 25 to rotate. Since the auxiliary shaft 25 is in contact with the conveyor belt 1, the rotation of the auxiliary shaft 25 will drive the conveyor belt 1 to perform transmission, which can provide additional power to the conveyor belt 1. This can adapt to the situation of conveying a large amount of heavy material or a long conveying distance. When the conveyor belt 1 extends and retracts, the tensioning unit 4 can keep the conveyor belt 1 taut at all times. This can keep the auxiliary shaft 25 in contact with the conveyor belt 1 at all times, which can improve the power transmission efficiency and effect.

[0065] Finally, the triangular bracket 21 provides greater stability when supporting the equipment, offering a larger contact area and stability compared to existing equipment. It maintains good support when transporting heavy materials. The support plate 26 connects to the first spline shaft 31 and the second spline shaft 32, allowing the triangular bracket 21 to move synchronously when the first spline shaft 31 and the second spline shaft 32 move. This enables the triangular bracket 21 to move synchronously when the conveyor belt 1 extends and retracts, thus providing better support for the adjustment unit 3.

[0066] By setting the second telescopic rod 22, auxiliary power can be provided when the triangular bracket 21 moves. Since the support plate 26 is connected to the first support shaft 33 and the second support shaft 33, the adjustment unit 3 can be adjusted synchronously when the second telescopic rod 22 pushes the triangular bracket 21 to move. At the same time, the triangular bracket 21 can be adjusted synchronously when the adjustment unit 3 is adjusted. It can be used for 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, the second telescopic rod 22 can also share the adjustment pressure of the adjustment unit 3.

[0067] The first spring 23 can generate a rebound when the triangular brackets 21 are too close, which can prevent collisions between the support plates 26. At the same time, it can apply a pull-back 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, which can retract the conveyor belt 1, thereby making the equipment easier to store and saving storage space.

[0068] When the conveyor belt 1 extends and retracts, the third telescopic rod 53 is set up so that it pushes 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, it can convert sliding friction into rolling friction, thereby reducing the friction during the movement of the equipment, reducing power consumption, and avoiding friction damage to the triangular bracket 21.
