Description

Technical Field

[0001] This application relates to the technical field of conveyor belts, and in particular to a retractable conveyor belt. Background Technology

[0002] Telescopic conveyor belts are primarily used in logistics warehousing, production lines, express delivery, airport baggage handling, supermarket checkouts, and food processing. They can quickly and efficiently transport materials and goods, improving work and production efficiency.

[0003] When existing telescopic conveyor belts are extended, the belts on the fixed frame and the belts on the sliding frame are not aligned, causing the materials to shake, bounce, or become unstable during transport. This can lead to materials slipping, tipping, or piling up, and may even cause material damage or personal injury.

[0004] It is evident that existing telescopic conveyor belts have a slope between the fixed end belt and the movable end belt, which causes instability during use. Summary of the Invention

[0005] To improve the stability of telescopic conveyor belts, this application provides a telescopic conveyor belt.

[0006] This application provides a telescopic conveyor belt, employing the following technical solution: It includes a fixed frame, with multiple first rotating shafts rotatably mounted on the end of the fixed frame away from the ground; an electric drum rotatably mounted on one end of the fixed frame, the electric drum being connected to an external power source; symmetrically formed sliding grooves on the end of the fixed frame near the ground, with sliders slidably mounted within the grooves; an adjusting shaft rotatably mounted on the sliders; a sliding frame slidably mounted on the fixed frame; and second and third rotating shafts rotatably mounted on the sliding frame. A belt is wound around the multiple first rotating shafts, the electric drum, the adjusting shaft, the second rotating shaft, and the third rotating shaft. The fixed frame is connected to two sets of drive mechanisms, symmetrically arranged about a line of symmetry of the fixed frame. The drive mechanisms drive the sliding frame to move. The sliding frame is connected to multiple sets of support mechanisms, which keep the belt level and support the belt.

[0007] By adopting the above technical solution, the drive mechanism drives the sliding frame to move, allowing the telescopic conveyor belt to extend. Furthermore, when the telescopic conveyor belt extends, the support mechanism keeps the belt flush between the sliding frame and the fixed frame and provides support for the belt, thus improving the stability of the telescopic conveyor belt.

[0008] Optionally, the drive mechanism includes: The motor is fixedly mounted on the mounting frame; A drive wheel is coaxially and fixedly mounted on the output end of the motor; A fixing block, which is fixedly installed with the sliding frame; Driven wheel, the driven wheel being rotatably connected to the fixed frame; A steel wire rope is wound around the driving pulley and the driven pulley, and both ends of the steel wire rope are fixedly connected to the fixed block.

[0009] By adopting the above technical solution, the fixed plate is displaced under the drive of the motor, which allows the sliding frame to move away from the fixed frame, thus realizing the telescopic function of the conveyor belt.

[0010] Optionally, the support mechanism includes: Two first mounting slots are symmetrically formed on the side wall where the sliding frame abuts against the fixed frame; Two first telescopic rods are fixedly installed on the bottom wall of the two first mounting slots, with the fixed ends of the two first telescopic rods corresponding to each other. The movable ends of the two first telescopic rods abut against the fixed frame. Two mounting plates are symmetrically arranged and slidably mounted on the sliding frame; A support shaft, which is rotatably mounted on the two mounting plates; Two second telescopic rods are provided, with their fixed ends fixedly mounted on the fixed frame. The movable ends of the second telescopic rods are fixedly connected to the two mounting plates one-to-one. The ends of the two first telescopic rods that are closer to their movable ends are connected to the ends of the two second telescopic rods that are farther from their movable ends. Two first springs are fixedly installed one-to-one with two first telescopic rods. One end of the first spring is fixedly connected to the fixed end of the first telescopic rod, and the other end of the first spring is fixedly connected to the movable end of the first telescopic rod.

[0011] By adopting the above technical solution, when the sliding frame moves away from the fixed frame, the support shaft can automatically move towards the first rotating shaft and become flush with the first rotating shaft, so that the belt between the fixed frame and the sliding frame can remain flush. This achieves the goal of making the fixed end belt and the movable end belt of the telescopic conveyor belt flush after it is extended, thus improving the stability of the telescopic conveyor belt.

[0012] Optionally, the movable end of the first telescopic rod that abuts against the fixed frame is hemispherical.

[0013] By adopting the above technical solution, the support shaft can automatically retract as the sliding frame moves towards the fixed frame, thus improving the ease of operation of the telescopic conveyor belt.

[0014] Optionally, multiple sets of auxiliary telescopic mechanisms are provided on both sides of the sliding frame near the ground, and the auxiliary telescopic mechanisms include: The second mounting slot is formed on the end of the sliding frame near the ground; A support rod, one end of which is hinged in the second mounting groove, and the support rod can be completely placed in the second mounting groove; The first rotating wheel is rotatably mounted on the end of the support rod away from the hinge end.

[0015] By adopting the above technical solution, the support rod can support and assist the movement of the sliding frame during its movement, thereby improving the stability of the telescopic conveyor belt.

[0016] Optionally, the hinged end of the support rod is located on the end of the second mounting groove near the electric drum.

[0017] By adopting the above technical solution, the support rod can automatically retract when the sliding frame moves towards the fixed frame, which improves the ease of operation of the telescopic conveyor belt.

[0018] Optionally, the end of the fixing frame that abuts against the support rod is configured as an arc surface.

[0019] By adopting the above technical solution, the downward rotation of the support rod is limited, thereby improving the safety of the telescopic conveyor belt.

[0020] Optionally, the support rod is connected to a locking mechanism, the locking mechanism comprising: The third telescopic rod has its fixed end fixedly installed on the sliding frame. The end of the fixed end of the third telescopic rod away from the movable end corresponds one-to-one with the end of the fixed end of the first telescopic rod close to the movable end and is connected to it. A slot is formed through the sliding frame and the support rod, and the movable end of the third telescopic rod can enter the slot.

[0021] By adopting the above technical solution, the third telescopic rod can lock the support rod after the first rotating wheel comes into contact with the ground, thereby improving the stability of the telescopic conveyor belt.

[0022] Optionally, it also includes two sets of tensioning mechanisms, which are symmetrically arranged about the axis of symmetry of the fixing frame. The tensioning mechanisms include: Two axles are slidably mounted on the fixed frame, and the two axles slide in opposite directions. Two tensioning pulleys are rotatably mounted on the wheel axle in a one-to-one correspondence, and both tensioning pulleys abut against the wire rope; Two second springs, one end of each of the two second springs is fixedly connected to the fixed frame, and the other end of each of the two second springs is fixedly connected to the two wheel axles one by one.

[0023] By adopting the above technical solution, the wire rope can always remain taut under the elastic force of the second spring, which helps to ensure the smooth movement of the sliding frame and further improves the stability of the telescopic conveyor belt.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. Driven by the motor, the fixed plate is displaced, allowing the sliding frame to move away from the fixed frame, thus realizing the telescopic function of the conveyor belt; 2. When the sliding frame moves away from the fixed frame, the support shaft can automatically move towards the first rotating shaft and become flush with it, so that the belt between the fixed frame and the sliding frame can remain flush. This achieves the alignment of the fixed end belt and the movable end belt of the telescopic conveyor belt after it is extended, thus improving the stability of the telescopic conveyor belt. 3. The curved surface can limit the speed during the downward rotation of the support rod, thus improving the safety of the telescopic conveyor belt. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0028] This application discloses a retractable transport belt.

[0029] Reference Figure 1 and Figure 2 A telescopic conveyor belt includes a fixed frame 1. Multiple first rotating shafts 11 are rotatably mounted on the end of the fixed frame 1 away from the ground. An electric drum 12 is rotatably mounted on one end of the fixed frame 1. Sliding grooves 13 are symmetrically opened on the fixed frame 1. A slider 14 is slidably mounted in the sliding groove 13. A slider 14 is rotatably mounted on the slider 14. An adjusting shaft 15 is rotatably mounted on the slider 14. A sliding frame 2 is slidably mounted on the fixed frame 1. A second rotating shaft 21 is rotatably mounted on one end of the sliding frame 2. A third rotating shaft 22 is rotatably mounted on the other end of the sliding frame 2. The multiple first rotating shafts 11, the electric drum 12, the second rotating shaft 21, and the third rotating shaft 22 are all wound around a belt 3. The fixed frame 1 is connected to two sets of drive mechanisms. The two sets of drive mechanisms are symmetrically arranged about the symmetry line of the fixed frame 1. The drive mechanisms are used to drive the sliding frame 2 to move. The sliding frame 2 is connected to multiple sets of support mechanisms 5. The support mechanisms 5 are used to support the belt 3 and keep the belt 3 flat.

[0030] In use, the drive mechanism can drive the sliding frame 2 to move away from the fixed frame 1, completing the extension and retraction of the belt 3. At the same time, the support mechanism 5 can support the belt 3 between the first rotating shaft 11 and the second rotating shaft 21, keeping the sliding frame 2 flush with the belt 3 on the fixed frame 1. When the telescopic conveyor belt is in use, the electric drum 12 drives the belt 3 to move, and the belt 3 drives multiple first rotating shafts 11, second rotating shafts 21, and third rotating shafts 22 to rotate, completing the transportation of items on the belt 3. Furthermore, the tension of the belt 3 can be achieved by the position of the slider 14 within the groove 13.

[0031] Reference Figure 1 and Figure 2The drive mechanism includes a motor 41, which is fixedly mounted on a fixed frame 1; a drive wheel 42 is coaxially fixedly mounted on the output end of the motor 41; a fixed block 43 is fixedly mounted on the sliding frame 2; a driven wheel 44 is rotatably connected to the fixed frame 1, and a steel wire rope 45 is wound on both the drive wheel 42 and the driven wheel 44, with both ends of the steel wire rope 45 fixedly connected to the fixed block 43.

[0032] In use, the motor 41 rotates to drive the drive wheel 42 to rotate, the drive wheel 42 drives the wire rope 45 to rotate, the wire rope 45 rotates to drive the driven wheel 44 to rotate, and at the same time, the fixed block 43 moves. The movement of the fixed block 43 allows the sliding frame 2 to move, realizing the extension and retraction of the belt 3 transport part.

[0033] Reference Figure 3 The support mechanism 5 includes two first mounting slots 51, which are symmetrically formed on the side walls of the sliding frame 2 and the fixed frame 1. A first telescopic rod 52 is fixedly mounted on the bottom wall of each of the two first mounting slots 51, and the movable end of each first telescopic rod 52 abuts against the fixed frame 1. Two mounting plates 53 are symmetrically arranged on the sliding frame 2, and the mounting plates 53 are slidably mounted on the sliding frame 2. The sliding direction of the mounting plates 53 is along the height direction of the sliding frame 2. A support shaft 54 ​​is rotatably mounted on both mounting plates 53. Two second telescopic rods 55 are fixedly mounted on the fixed frame 1. The movable end of the telescopic rod 55 is fixedly connected to the two mounting plates 53 one-to-one. The fixed ends of the two second telescopic rods 55, away from the movable end, are connected to the fixed ends of the two first telescopic rods 52, near the movable end. The cavity connecting the fixed ends of the second telescopic rods 55, away from the movable end, and the fixed ends of the first telescopic rods 52, near the movable end, is filled with hydraulic oil. Each of the two first telescopic rods 52 is fitted with a first spring 56. One end of the first spring 56 is fixedly connected to the fixed end of the first telescopic rod 52, and the other end of the first spring 56 is fixedly connected to the movable end of the first telescopic rod 52.

[0034] In use, the movable end of the first telescopic rod 52 abuts against the side wall of the fixed frame 1, compressing the first spring 56. When the movable end of the first telescopic rod 52 moves to a position where it is no longer abutting against the fixed frame 1, the movable end of the first telescopic rod 52 moves away from the fixed end under the elastic force of the first spring 56. At this time, the hydraulic oil in the fixed end of the first telescopic rod 52 near the movable end is pushed into the fixed end of the second telescopic rod 55 away from the movable end, causing the movable end of the second telescopic rod 55 to move away from the fixed end, driving the mounting plate 53 to move upward, thereby causing the support shaft 54 ​​to move upward to a position flush with the first rotating shaft 11.

[0035] Reference Figure 3 The movable end of the first telescopic rod 52 that abuts against the fixed frame 1 is hemispherical.

[0036] The hemispherical shape allows the movable end of the first telescopic rod 52 to be pressed by the fixed frame 1 when the sliding frame 2 moves toward the fixed frame 1, thereby allowing the support shaft 54 ​​to return to its original position.

[0037] Reference Figure 3 Multiple sets of auxiliary telescopic mechanisms 6 are provided on both sides of the sliding frame 2 near the ground. The auxiliary telescopic mechanism 6 includes a second mounting groove 61, which is opened on the sliding frame 2 near the ground. A support rod 62 is hinged in the second mounting groove 61, and the support rod 62 can be completely placed in the second mounting groove 61. A first rotating wheel 63 is rotatably installed on the end of the support rod 62 away from the hinge end.

[0038] When the sliding frame 2 moves to a position where the second mounting slot 61 is not in contact with the fixed frame 1, the support rod 62 rotates downward under its own weight, causing the first rotating wheel 63 to come into contact with the ground. The sliding frame 2 continues to move away from the fixed frame 1, making the support rod 62 perpendicular to the ground. At the same time, the first rotating wheel 63 begins to rotate, assisting the sliding frame 2 in sliding. When the sliding frame 2 stops moving, the support rod 62 and the first rotating wheel 63 together provide support for the sliding frame 2.

[0039] Reference Figure 2 The hinged end of the support rod 62 is located on the end of the mounting groove 51 near the electric drum 12.

[0040] As the sliding frame 2 moves toward the fixed frame 1, it causes the support rod 62 to move. When the support rod 62 moves to the position where it abuts against the fixed frame 1, the support rod 62 is blocked by the fixed frame 1, so that the support rod 62 can be automatically retracted into the second mounting slot 61.

[0041] Reference Figure 2 The end of the fixed frame 1 that abuts against the support rod 62 is set as an arc surface.

[0042] The support rod 62 remains tangent to the arc surface during its downward rotation, thus limiting the speed of its downward rotation.

[0043] Reference Figure 4 The support rod 62 is connected to a locking mechanism 7, which includes a third telescopic rod 71. The fixed end of the third telescopic rod 71 is fixedly installed on the sliding frame 2. The fixed end of the third telescopic rod 71 away from the movable end corresponds to and is connected to the fixed end of the first telescopic rod 52 away from the movable end. The cavity connecting the fixed end of the third telescopic rod 71 away from the movable end and the fixed end of the first telescopic rod 52 near the movable end is filled with hydraulic oil. A slot 72 is provided through the sliding frame 2 and the support rod 62, and the movable end of the third telescopic rod 71 can enter the slot 72.

[0044] When the movable end of the first telescopic rod 52 moves away from the fixed end, the hydraulic oil in the fixed end of the first telescopic rod 52 near the movable end is squeezed into the fixed end of the third telescopic rod 71 away from the movable end, causing the movable end of the third telescopic rod 71 to move away from the fixed end and enter the slot 72.

[0045] Reference Figure 5 It also includes two sets of tensioning mechanisms 8, which are symmetrically arranged about the axis of symmetry of the fixed frame 1. Each tensioning mechanism 8 includes two axles 81, which are slidably mounted on the end of the fixed frame 1 near the motor 41. The sliding directions of the two axles 81 are opposite. Tensioning wheels 82 are rotatably mounted on the two axles 81, and both tensioning wheels 82 abut against the wire rope 45. A second spring 83 is fixedly connected to each of the two axles 81, and the end of the second spring 83 away from the axle 81 is fixedly connected to the fixed frame 1.

[0046] When the wire rope 45 is stretched after long-term use, the second spring 83 can automatically adjust the position of the wheel axle 81 according to the length of the wire rope 45, so that the wire rope 45 can always be in contact with the tension wheel 82 and remain taut.

[0047] The implementation principle of a telescopic conveyor belt according to an embodiment of this application is as follows: During use, the movable end of the first telescopic rod 52 abuts against the side wall of the fixed frame 1, causing the first spring 56 to be compressed. When the movable end of the first telescopic rod 52 moves to a position where it is not in contact with the fixed frame 1, the movable end of the first telescopic rod 52 moves away from the fixed end under the elastic force of the first spring 56. At this time, the hydraulic oil in the fixed end of the first telescopic rod 52 near the movable end is pushed into the fixed end of the second telescopic rod 55 away from the movable end, causing the movable end of the second telescopic rod 55 to move away from the fixed end, driving the mounting plate 53 to move upward, thereby causing the support shaft 54 ​​to move upward to a position flush with the first rotating shaft 11. At the same time, when the sliding frame 2 moves to a position where the second mounting groove 61 is not in contact with the fixed frame 1, the support rod 62 rotates downward under its own weight, causing the first rotating wheel 63 to abut against the ground. The sliding frame 2 continues to move away from the fixed frame 1, making the support rod 62 perpendicular to the ground. At the same time, the first rotating wheel 63 starts to rotate, assisting the sliding frame 2 to slide. When the sliding frame 2 stops moving, the support rod 62 and the first rotating wheel 63 together support the sliding frame 2, improving the stability of the telescopic conveyor belt.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
