Description

Technical Field

[0001] This utility model belongs to the technical field of telescopic belt conveyors, specifically relating to a telescopic belt conveyor with an adjustable ramp device at the tail end. Background Technology

[0002] Telescopic belt conveyors are ordinary belt conveyors with an added telescopic mechanism, allowing the conveyor to extend and retract freely along its length. Users can adjust the buttons to control the conveyor's length at any time. Models equipped with automatic lifting devices also allow users to control the height of the conveyor's end. This significantly reduces the distance for manual material handling, shortens loading and unloading time, reduces labor intensity, minimizes product damage, lowers loading and unloading costs, and improves work efficiency. However, existing belt conveyors may experience issues such as: the upper end being at a suitable height, but the lower end being higher than the loading / unloading platform but significantly lower, or the lower end being lower than the platform. This can prevent smooth transport of goods from the telescopic belt conveyor to the loading / unloading platform, and may even damage goods when they fall onto the platform due to significant impact. Utility Model Content

[0003] The purpose of this utility model is to solve the problems existing in the prior art, thereby providing a telescopic belt conveyor with an adjustable ramp device at the tail end. The belt tilt angle at the end of the telescopic belt conveyor can be freely adjusted, thereby realizing the smooth transportation of goods from the telescopic belt conveyor to the loading and unloading platform. This prevents the goods on the upper surface of the belt from being damaged due to excessive impact force when they fall onto the loading and unloading platform because of the large height difference between the belt telescopic conveyor and the loading and unloading platform.

[0004] The purpose of this utility model is achieved as follows: A telescopic belt conveyor with an adjustable ramp at the tail end includes a frame, on which several transmission mechanisms are arranged, adjacent transmission mechanisms are telescopically and slidably connected, a conveyor belt is arranged on the upper surface of the transmission mechanism, a support beam is connected to the end of the frame, the two ends of the support beam are fixedly connected to a support plate near the center, the end of the support plate is rotatably connected to the frame, and an angle adjustment mechanism is connected to the movable end of the support plate, an mounting plate is arranged on the inner side of the support plate, the mounting plate is fixedly connected to the support beam, a tensioning roller is arranged between the two mounting plates, the tensioning roller is rotatably connected to a tensioning shaft, the two ends of the tensioning shaft are connected to the mounting plate, the conveyor belt is wound around the outside of the conveying shaft, idler roller and tensioning roller on the transmission mechanism, and a drive device is connected to the conveying shaft.

[0005] Furthermore, the angle adjustment mechanism includes an arc-shaped elongated hole on the frame, in which a locking bolt is installed. The inner end of the locking bolt passes through the arc-shaped elongated hole and is connected to the movable end of the support plate by a thread. The center of the arc-shaped elongated hole is located on the central axis of rotation of the support beam. By rotating the locking bolt, the connection between the locking bolt and the frame is loosened. At this time, the movable end of the support plate can be rotated to any angle position by holding it. Then, the locking bolt is tightened. The friction between the head of the locking bolt and the frame is used to fix the movable end of the support plate to the frame.

[0006] Furthermore, the angle adjustment mechanism includes an adjusting screw hinged to the support beam. The adjusting screw is connected to the adjusting sleeve via a thread, and the adjusting sleeve is rotatably connected to the frame via a horizontal axis. A rotating handle is connected to the movable end of the adjusting screw. Rotating the rotating handle causes the adjusting screw to move relative to the adjusting sleeve toward or away from the support plate (the angle between the axis of the adjusting sleeve and the horizontal plane changes accordingly), thereby adjusting the horizontal distance between the movable end of the support beam and the support plate and the horizontal axis, thus achieving the purpose of adjusting the tilt angle of the support plate.

[0007] Furthermore, roller guards are provided at both ends of the tensioning shaft to prevent the rollers from causing injury to the human body during rotation.

[0008] Furthermore, a groove is provided at one end of the mounting plate away from the supporting crossbeam. Both ends of the tensioning shaft are slidably disposed in the groove. An adjusting bolt is provided in the groove, and the axial direction of the adjusting bolt is parallel to the axial direction of the groove. The adjusting bolt is connected to the tensioning shaft by a thread. The adjusting bolt is rotatably connected to a fixing block on the outer surface of the mounting plate. Rotating the adjusting bolt can drive the tensioning shaft to move back and forth along the groove. Adjusting one end of the tensioning shaft forward / backward can prevent the belt from running off-center.

[0009] The beneficial effects of this utility model are:

[0010] 1. This utility model has an adjustable support plate at the rear of the frame. The support plate can be used to adjust the tilt angle of the belt at the end of the telescopic conveyor, thereby adjusting the drop between the end of the telescopic conveyor and the loading and unloading platform. This ensures smooth transportation of goods from the telescopic conveyor to the loading and unloading platform and prevents the goods on the belt from being damaged due to excessive impact when they fall onto the loading and unloading platform.

[0011] 2. In this utility model, the tilt angle of the support plate is controlled by an angle adjustment mechanism. The tilt angle of the support plate can be quickly adjusted and locked through the angle adjustment mechanism, which is convenient to operate.

[0012] 3. This utility model has roller guards at both ends of the tensioning shaft, which can prevent the rollers from causing injury to the human body during rotation. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, a telescopic belt conveyor with an adjustable ramp at the tail end includes a frame 1. Several transmission mechanisms 2 are mounted on the frame 1, and adjacent transmission mechanisms 2 are telescopically slidably connected. A conveyor belt 17 is mounted on the upper surface of each transmission mechanism 2. A support beam 4 is connected to the end of the frame 1. Both ends of the support beam 4 are fixedly connected to a support plate 3 near the center. The end of the support plate 3 is rotatably connected to the frame 1, and an angle adjustment mechanism is connected to the movable end of the support plate 3. An mounting plate 5 is mounted on the inner side of the support plate 3. The mounting plate 5 is fixedly connected to the support beam 4. A tensioning roller 6 is mounted between two mounting plates 5. The tensioning roller 6 is rotatably connected to a tensioning shaft 7. Both ends of the tensioning shaft 7 are connected to the mounting plate 5. The conveyor belt 17 is wound around the outside of the conveyor shaft 15, idler roller 16, and tensioning roller 6 on the transmission mechanism 2. A drive device 14 is connected to the conveyor shaft 15.

[0028] In use, this invention first adjusts the relative position of the transmission mechanism 2 as needed to adjust the working length of the telescopic belt. Then, based on the height difference between the loading / unloading platform and the end of the transmission mechanism 2, the tilt angle of the support plate 3 is adjusted via the angle adjustment mechanism. Finally, the belt 17 is tightened. When the height of the loading / unloading platform is higher than the end of the telescopic belt conveyor, the movable end of the support plate 3 is flipped upwards to match the height of the loading / unloading platform, thus achieving smooth transport of goods from the lower telescopic belt conveyor to the higher loading / unloading platform. When the height of the loading / unloading platform is lower than the end of the telescopic belt conveyor, the movable end of the support plate 3 is flipped downwards, effectively reducing the height difference between the end transmission mechanism 2 and the loading / unloading platform (the height difference can be adjusted to within 10cm), thus achieving smooth transport of goods from the higher telescopic belt conveyor to the lower loading / unloading platform, reducing the impact force when goods fall onto the loading / unloading platform, and preventing damage to the goods.

[0029] In one embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the angle adjustment mechanism includes an arc-shaped elongated hole 11 on the frame 1. A locking bolt 12 is installed in the arc-shaped elongated hole 11. The inner end of the locking bolt 12 passes through the arc-shaped elongated hole 11 and is connected to the movable end of the support plate 3 by a thread. The center of the arc-shaped elongated hole 11 is located on the central axis of the support beam 4. By rotating the locking bolt 12, the connection between the locking bolt 12 and the frame 1 is loosened. At this time, the movable end of the support plate 3 can be rotated to any angle position by holding it. Then, the locking bolt 12 is tightened. The friction between the head of the locking bolt 12 and the frame 1 is used to fix the movable end of the support plate 3 to the frame 1.

[0030] In one embodiment of this utility model, such as Figure 4As shown, the angle adjustment mechanism includes an adjusting screw 18 hinged to the support beam 4. The adjusting screw 18 is connected to the adjusting sleeve 19 by a thread. The adjusting sleeve 19 is rotatably connected to the frame 1 by a horizontal shaft 20. The movable end of the adjusting screw 18 is connected to a rotating handle 21. Rotating the rotating handle 21 causes the adjusting screw 18 to move relative to the adjusting sleeve 19 toward or away from the support plate 3 (the angle between the axis of the adjusting sleeve 19 and the horizontal plane changes accordingly). This adjusts the horizontal distance between the movable end of the support beam 4 and the support plate 3 and the horizontal shaft 20, thereby achieving the purpose of adjusting the tilt angle of the support plate 3.

[0031] In one embodiment of this utility model, such as Figure 5 As shown, roller guards 13 are provided at both ends of the tensioning shaft 7. The roller guards 13 can prevent the roller from causing injury to the human body when rotating.

[0032] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, a groove 9 is provided at one end of the mounting plate 5 away from the supporting beam 4. Both ends of the tensioning shaft 7 are slidably disposed in the groove 9. An adjusting bolt 10 is provided in the groove 9. The axis of the adjusting bolt is parallel to the axis of the groove 9. The adjusting bolt 10 is connected to the tensioning shaft 7 by a thread. The adjusting bolt 10 is rotatably connected to the fixing block 8 on the outer side of the mounting plate 5. Rotating the adjusting bolt 10 can drive the tensioning shaft 7 to move back and forth along the groove 9. By adjusting one end of the tensioning shaft 7 forward / backward, the belt 17 can be prevented from running off-center.

[0033] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
