Description

Technical Field

[0001] The present invention relates to the field of conveyor belt edge sealing, and particularly to an edge sealing device for a felt conveyor belt and an edge sealing docking and pressing method therefor. Background Art

[0002] A conveyor belt, also known as a transport belt, is a rubber, fiber, metal composite product or a plastic and fabric composite product used to carry and transport materials in a belt conveyor. It is widely used in industries such as cement, coking, metallurgy, chemical industry, and steel for occasions with short conveying distances and small conveying volumes.

[0003] When a felt conveyor belt is running, the middle strong layer of the edge will fluff up. When transporting in the electronic CC industry, fluffing will cause pollution to the transported items, resulting in losses. When the existing felt conveyor belt edge sealing device is in use, it is inconvenient to seal felt conveyor belts with different widths and thicknesses, resulting in the need for factories to purchase different models of edge sealing devices. And the device that can seal different thicknesses and widths has a complex structure and is not convenient for maintenance and repair. Therefore, the present invention proposes an edge sealing device for a felt conveyor belt and an edge sealing docking and pressing method therefor. Summary of the Invention

[0010] As a further solution of the present invention: The thickness adjustment mechanism further includes a heat-sealing rod and a rotating rod. The heat-sealing rod is located inside the main body and one end is fixedly connected to the first runner. The rotating rod is located on the outer wall of one side of the second gear and is fixedly connected thereto. One end of the rotating rod penetrates to the outer wall of the other side of the second gear and is connected to a main motor. A second conveyor belt is arranged on the outer wall of the rotating rod on one side of the second gear. A receiving rod is arranged on the inner side of one end of the second conveyor belt.

[0011] As a further solution of the present invention: The engaging mechanism further includes a movable rod located on the outer walls of the first pressing rod and the second pressing rod and inside the first runner. A spring is arranged on the outer wall of the movable rod.

[0012] As a further solution of the present invention: The width adjustment mechanism further includes a first lead screw and a limiting plate. The first lead screw is located inside the first slider and the second slider and penetrates to the outer walls of the first slider and the second slider. The limiting plate is located at the top of the first slider and the second slider. One end of the first lead screw is connected to a driving motor.

[0013] As a further solution of the present invention: The lifting mechanism further includes a second lead screw located at the bottom end of the lifting rod and inside the sleeve. One end of the second lead screw is connected to a third gear. A fourth gear is arranged on the outer wall of the third gear. The outer wall of the fourth gear is rotationally connected to a lifting motor through a rotating rod.

[0014] As a further solution of the present invention: A chute matching the moving tracks of the first slider and the second slider is arranged on the inner wall of the main body. The outer walls of the first slider and the second slider are in a "convex" shape. Threads matching the outer wall of the first lead screw are arranged on the inner walls of the first slider and the second slider. The threads on the inner walls of the first slider and the second slider are in opposite states.

[0015] As a further solution of the present invention: Threads matching the outer wall of the second lead screw are arranged on the inner wall of the lifting rod. The outer wall of the sleeve fits with the inner wall of the lifting rod. The outer walls of the third gear and the fourth gear are meshed with each other.

[0016] As a further solution of the present invention: a chute matching the rotation trajectory of the first runner is provided on the inner wall of the main body, the outer walls of the first gear and the second gear are meshed, and the outer wall of the first conveyor belt is in a triangular state.

[0017] A method for edge sealing and butt joint pressing of a felt conveyor belt includes the following steps:

[0018] S1: First, pass the felt conveyor belt and the edge sealing block through the upper part of the telescopic rod inside the conveying rod and through the limiting plate to the inside of the main body, and then pass the conveyor belt and the edge sealing block through the inside of the heat sealing rod to the outside of the main body and wind them around the storage rod.

[0019] S2: Then start the lifting motor. The lifting motor drives the fourth gear to rotate. The rotation of the fourth gear drives the third gear meshed with its outer wall to rotate. The rotation of the third gear drives the second lead screw to rotate. Since the outer wall of the lifting rod is rectangular, the rotation of the second lead screw causes the lifting rod to move along the inner wall of the sleeve under the action of the thread on its inner wall. The movement of the lifting rod drives the telescopic rod to move, thereby applying pressure to the felt conveyor belt to make it taut and reducing wrinkles.

[0020] S3: Then start the driving motor. The driving motor drives the first lead screw to rotate. The rotation of the first lead screw causes the first slider and the second slider on its outer wall to move along the inner chute of the main body under the action of the thread on its inner wall. Since the threads on the inner walls of the first slider and the second slider are in opposite states, the first slider and the second slider will move away from or close to each other under the action of the thread until the distance between the two limiting plates is about the same as the width of the felt conveyor belt, making it applicable to felt conveyor belts of different widths.

[0021] S4: Then apply pressure to the first pressing rod and the second pressing rod to make the first pressing rod and the second pressing rod approach each other along the inner chute of the first runner. At this time, the first pressing rod and the second pressing rod will drive the movable rod on the outer wall of one side to move. The movement of the movable rod applies pressure to the spring until one end of the first pressing rod and the second pressing rod moves out of the inner wall card slot of the main body. At this time, a thrust can be applied to the first runner to make the first runner move along the inner chute of the main body. The movement of the first runner drives the heat sealing rod to move until the outer walls of the two first runners are in contact with the outer walls of the felt conveyor belt and the edge sealing block to clamp them, thereby adapting to felt conveyor belts of different thicknesses.

[0022] S5: Finally, start the main motor. The operation of the main motor will drive the rotating rod connected to its outer wall to rotate. The rotating rod will drive the second conveyor belt and the second gear located on its outer wall to rotate. The second gear will drive the first gear meshing with its outer wall to rotate. The rotation of the first gear will drive the first conveyor belt located on its outer wall to move. At this time, the first runner and the second runner sleeved on the inner side of the first conveyor belt will also rotate. The rotation of the first runner will drive the heat-sealing rod to rotate, thereby heat-sealing the felt conveyor belt and the edge-sealing block. The movement of the second conveyor belt will drive the storage rod to rotate, thereby storing the felt conveyor belt with the edge-sealing completed on the outer wall of the storage rod.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. By setting the thickness adjustment mechanism, by applying pressure to the first pressing rod and the second pressing rod, the first pressing rod and the second pressing rod move closer to each other along the inner wall chute of the first runner. At this time, the first pressing rod and the second pressing rod will drive the movable rod located on the outer wall of one side to move. The movement of the movable rod will apply pressure to the spring until one end of the first pressing rod and the second pressing rod moves out of the inner wall card slot of the main body. At this time, a thrust can be applied to the first runner, so that the first runner moves along the inner wall chute of the main body. The movement of the first runner will drive the heat-sealing rod to move until the outer walls of the two first runners are in contact with the outer walls of the felt conveyor belt and the edge-sealing block, and clamp them, so as to adapt to felt conveyor belts of different thicknesses;

[0025] 2. By setting the width adjustment mechanism, by starting the driving motor to operate, the first lead screw will be driven to rotate. The rotation of the first lead screw will cause the first slider and the second slider located on its outer wall to move along the inner chute of the main body under the action of the internal thread on its wall. Since the internal threads of the first slider and the second slider are in opposite states, the first slider and the second slider will move away from or close to each other under the action of the thread until the distance between the two limit plates is about the same as the width of the felt conveyor belt, making it applicable to felt conveyor belts of different widths;

[0026] 3. By setting the lifting mechanism, by starting the lifting motor, the operation of the lifting motor will drive the fourth gear to rotate. The rotation of the fourth gear will drive the third gear meshing with its outer wall to rotate. The rotation of the third gear will drive the second lead screw to rotate. Since the outer wall of the lifting rod is rectangular, the rotation of the second lead screw will cause the lifting rod to move along the inner wall of the sleeve under the action of the internal thread on its wall. The movement of the lifting rod will drive the telescopic rod to move, thereby applying pressure to the felt conveyor belt to make it taut and reducing wrinkles. Description of the Drawings

[0052] S1: First, pass the felt conveyor belt and the edge sealing block through the upper part of the telescopic rod 3 inside the conveying rod 2 and through the limiting plate 701 into the interior of the main body 1, and then pass the conveyor belt and the edge sealing block through the inner wall of the heat sealing rod 501 to the outside of the main body 1 and wind them around the storage rod 510.

[0053] S2: Then start the lifting motor 806. When the lifting motor 806 works, it will drive the fourth gear 805 to rotate. The rotation of the fourth gear 805 will drive the third gear 804 meshed with its outer wall to rotate. The rotation of the third gear 804 will drive the second lead screw 803 to rotate. Since the outer wall of the lifting rod 801 is rectangular, the rotation of the second lead screw 803 will cause the lifting rod 801 to move along the inner wall of the sleeve 802 under the action of the threads on its inner wall.

[0054] S3: Then start the drive motor 705. When the drive motor 705 operates, it will drive the first lead screw 703 to rotate. As the first lead screw 703 rotates, the first slider 702 and the second slider 704 located on its outer wall will move along the inner chute of the main body 1 under the action of the threads on their inner walls. Since the threads on the inner walls of the first slider 702 and the second slider 704 are in opposite states, the first slider 702 and the second slider 704 will move away from or close to each other under the action of the threads until the distance between the two limit plates 701 is approximately the same as the width of the felt conveyor belt, making it applicable to felt conveyor belts of different widths;

[0055] S4: Then apply pressure to the first pressing rod 601 and the second pressing rod 602, causing the first pressing rod 601 and the second pressing rod 602 to approach each other along the inner chute of the first runner 502. At this time, the first pressing rod 601 and the second pressing rod 602 will drive the movable rod 603 located on their outer walls to move. The movement of the movable rod 603 will apply pressure to the spring 604 until one end of the first pressing rod 601 and the second pressing rod 602 moves out of the inner wall slot of the main body 1. At this time, a thrust can be applied to the first runner 502, causing the first runner 502 to move along the inner chute of the main body 1. The movement of the first runner 502 will drive the heat-sealing rod 501 to move until the outer walls of the two first runners 502 are in contact with the outer walls of the felt conveyor belt and the edge-sealing block, clamping them, thus adapting to felt conveyor belts of different thicknesses;

[0056] S5: Finally, start the main motor 507. When the main motor 507 operates, it will drive the rotating rod 508 connected to its outer wall to rotate. The rotating rod 508 will drive the second conveyor belt 509 and the second gear 506 located on its outer wall to rotate.

The edge-sealing device for a felt conveyor belt according to claim 1, characterized in that, A chute matching the movement trajectories of the first slider (702) and the second slider (704) is provided on the inner wall of the main body (1). The outer walls of the first slider (702) and the second slider (704) are in a "convex" shape. Threads matching the outer wall of the first lead screw (703) are provided on the inner walls of the first slider (702) and the second slider (704). The threads on the inner walls of the first slider (702) and the second slider (704) are in opposite states.

4. The edge-sealing device for a felt conveyor belt according to claim 2, characterized in that, Threads matching the outer wall of the second lead screw (803) are provided on the inner wall of the lifting rod (801). The outer wall of the sleeve (802) fits with the inner wall of the lifting rod (801). The outer walls of the third gear (804) and the fourth gear (805) are meshed with each other.

5. A butt-joint pressing method using the edge-sealing device for a felt conveyor belt according to claim 2, characterized in that, It includes the following steps: S1: First, pass the felt conveyor belt and the edge sealing block through the upper part of the telescopic rod (3) inside the conveying rod (2), through the limit plate (701) and into the interior of the main body (1), and then pass the conveyor belt and the edge sealing block through the inner wall of the heat sealing rod (501) to the outside of the main body (1) and wind them around the storage rod (510). S2: Then start the lifting motor (806). When the lifting motor (806) operates, it will drive the fourth gear (805) to rotate. The rotation of the fourth gear (805) will drive the third gear (804) meshing with its outer wall to rotate. The rotation of the third gear (804) will drive the second lead screw (803) to rotate. Since the outer wall of the lifting rod (801) is rectangular, the rotation of the second lead screw (803) will cause the lifting rod (801) to move along the inner wall of the sleeve (802) under the action of the internal thread on its inner wall. The movement of the lifting rod (801) will drive the telescopic rod (3) to move, thereby applying pressure to the felt conveyor belt to make it taut and reducing wrinkles. S3: Then start the drive motor (705). When the drive motor (705) operates, it will drive the first lead screw (703) to rotate. The rotation of the first lead screw (703) will cause the first slider (702) and the second slider (704) located on its outer wall to move along the internal chute of the main body (1) under the action of the internal thread on its inner wall. Since the internal threads of the first slider (702) and the second slider (704) are in opposite states, the first slider (702) and the second slider (704) will move away from or close to each other under the action of the threads until the distance between the two limit plates (701) is approximately the same as the width of the felt conveyor belt, making it suitable for felt conveyor belts of different widths. S4: Then apply pressure to the first pressing rod (601) and the second pressing rod (602) to make the first pressing rod (601) and the second pressing rod (602) approach each other along the inner chute of the first runner (502). At this time, the first pressing rod (601) and the second pressing rod (602) will drive the movable rod (603) located on one side of their outer walls to move. The movement of the movable rod (603) will apply pressure to the spring (604) until one end of the first pressing rod (601) and the second pressing rod (602) moves out of the inner wall slot of the main body (1). At this time, a thrust can be applied to the first runner (502) to make the first runner (502) move along the inner chute of the main body (1). The movement of the first runner (502) will drive the heat-sealing rod (501) to move until the outer walls of the two heat-sealing rods (501) come into contact with the outer walls of the felt conveyor belt and the edge-sealing block, clamping them, so as to adapt to felt conveyor belts of different thicknesses. S5: Finally, start the main motor (507). The operation of the main motor (507) will drive the rotating rod (508) connected to its outer wall to rotate. The rotating rod (508) will drive the second conveyor belt (509) and the second gear (506) located on its outer wall to rotate. The rotation of the second gear (506) will drive the first gear (505) meshed with its outer wall to rotate. The rotation of the first gear (505) will drive the first conveyor belt (503) located on its outer wall to drive. At this time, the first runner (502) and the second runner (504) sleeved inside the first conveyor belt (503) will also rotate. The rotation of the first runner (502) will drive the heat-sealing rod (501) to rotate, thereby heat-sealing the felt conveyor belt and the edge-sealing block. The transmission of the second conveyor belt (509) will drive the storage rod (510) to rotate, thereby storing the felt conveyor belt with the edge-sealing completed located on the outer wall of the storage rod (510).
