Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically to a telescopic chain conveyor. Background Technology

[0002] In modern logistics warehousing, manufacturing and other fields, efficient material transfer is a key link to ensure smooth overall operation and improve production and loading and unloading efficiency. As the core equipment for realizing automated and continuous material transportation, conveyors are widely used for material location transportation, replacing the traditional forklift function. The stability and adaptability of their operation directly affect the company's operating costs and work efficiency.

[0003] Existing material conveying equipment is mainly divided into two types: fixed conveyors and combinations of multiple transfer devices. Fixed conveyors, due to their fixed structure, cannot adjust their conveying length after manufacturing. In actual logistics loading and unloading operations, when encountering trucks with varying lengths, fixed conveyors often struggle to achieve precise docking with the trucks. Either the conveying length is insufficient, requiring manual handling of materials for loading and unloading, or the conveying length is too long, exceeding the truck's capacity and resulting in wasted space. When the production line layout changes, fixed conveyors cannot be adjusted to meet new conveying distance requirements, necessitating the purchase or modification of new equipment, significantly limiting their applicability. While combinations of multiple transfer devices can adjust conveying distances to some extent through equipment pairing, this method requires higher equipment purchase costs. Simultaneous operation of multiple devices increases power consumption and maintenance costs, and material jamming and accumulation can easily occur at the joints between devices, affecting conveying efficiency. Utility Model Content

[0004] To address the limitations of existing technologies, such as fixed conveyors with fixed conveyor lengths that cannot be adjusted, making them unsuitable for situations with varying truck bed lengths and limiting their applicability; and the high procurement, operating, and maintenance costs of combining multiple transfer devices, as well as the susceptibility to material issues at equipment connections that affect conveying efficiency, this invention provides a telescopic chain conveyor.

[0005] The objective of this utility model can be achieved through the following technical solutions: A telescopic chain conveyor includes a main beam, with a telescopic beam slidably mounted on the upper surface of one end of the main beam. A tension sprocket, a third sprocket, and a fourth sprocket are rotatably mounted on the inner side wall of the end of the main beam away from the telescopic beam. A fixed nylon guide strip is fixedly connected to the upper surface of the main beam, and a dynamic nylon guide strip is provided on the upper surface of the telescopic beam. Chains are meshed on the first sprocket, the telescopic sprocket, the tension sprocket, and the third sprocket. The first sprocket is rotatably connected to the end of the telescopic beam away from the main beam, and the telescopic sprocket is rotatably connected to the other end of the telescopic beam.

[0006] Furthermore, the main beam and the telescopic beam are distributed in parallel, and nylon guide blocks are provided between the main beam and the telescopic beam.

[0007] Furthermore, the main beam is equipped with a lead screw, which is set parallel to the main beam. The end of the lead screw away from the telescopic beam is rotatably connected to a synchronous gear, which meshes with a synchronous toothed belt, which meshes with the output end of the first motor.

[0008] Furthermore, an adjusting nut is threaded onto the lead screw, a flange is fixedly connected to one side of the adjusting nut, a bearing bracket is fixedly connected to the flange, and the bearing bracket is fixedly connected to the telescopic beam.

[0009] Furthermore, the tension sprocket, the third sprocket, and the fourth sprocket are arranged sequentially from top to bottom; the inner sidewall of the chain is sequentially engaged with the first sprocket, the tension sprocket, the third sprocket, and the second sprocket, and the outer sidewall of the chain is sequentially engaged with the second sprocket and the telescopic sprocket; the second sprocket is located between the tension sprocket and the third sprocket, and the telescopic sprocket is located between the first sprocket and the second sprocket.

[0010] Furthermore, a top cover plate is fixedly provided on the upper surface of the main beam on the opposite side; a support plate is fixedly provided on the opposite side of the main beam.

[0011] Furthermore, a conveyor shaft is provided between the main beams, with a third sprocket rotatably connected to both ends of the conveyor shaft. One end of the conveyor shaft passes through the main beam and connects to the output end of the second motor. A connecting block is rotatably connected to the conveyor shaft and is fixedly connected to the rear beam. Photoelectric accessories are installed above the pallets.

[0012] The beneficial effects of this utility model are: This invention uses a first motor to control the rotation of a lead screw. The rotation of the lead screw drives an adjusting nut to move forward or backward, which in turn drives a flange to move forward or backward. The flange then drives a bearing bracket to move forward or backward, which in turn drives a telescopic beam to move forward or backward. The telescopic beam's forward or backward movement simultaneously drives the first sprocket and the telescopic sprocket to move forward or backward. This allows for free extension and retraction of the conveyor length. During logistics loading and unloading, the length of the truck bed varies, and the telescopic conveyor can flexibly match and perfectly connect with the production line. It can quickly adjust the conveying distance according to changes in the process layout. When not in operation, it retracts to its shortest state to reduce space occupation, improve work efficiency, and reduce manual handling costs. Compared to fixed conveyors and combinations of multiple transfer devices, it saves on equipment procurement and maintenance costs and can be adapted for operation in various situations.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 As shown, a telescopic chain conveyor includes a main beam 1, which is symmetrically arranged. A telescopic beam 2 is slidably provided on the upper surface of one end of the main beam 1. The main beam 1 and the telescopic beam 2 are distributed in parallel. A nylon guide block 14 is provided between the main beam 1 and the telescopic beam 2. The nylon guide block 14 is used to guide the extension or shortening of the telescopic beam 2. A first sprocket 4 is rotatably connected to one end of the telescopic beam 2 away from the main beam 1, and a telescopic sprocket 7 is rotatably connected to the other end of the telescopic beam 2. The first sprocket 4 and the telescopic sprocket 7 move as the telescopic beam 2 moves.

[0017] The main beam 1 is equipped with a lead screw 3, which is set parallel to the main beam 1. The end of the lead screw 3 away from the telescopic beam 2 is rotatably connected to a synchronous gear 1002. The synchronous gear 1002 meshes with a synchronous toothed belt 1001, which meshes with the output end of the first motor 10.

[0018] The first motor 10 drives the synchronous toothed belt 1001, which in turn drives the synchronous gear 1002 to rotate, and the rotation of the synchronous gear 1002 drives the lead screw 3 to rotate.

[0019] A tensioning sprocket 8, a third sprocket 6, and a fourth sprocket 9 are rotatably provided on the inner side wall of the end of the main beam 1 away from the telescopic beam 2; the tensioning sprocket 8, the third sprocket 6, and the fourth sprocket 9 are arranged sequentially from top to bottom; the third sprocket 6 is used to adjust the tension of the chain 18; a second sprocket 5 is rotatably provided on the inner side wall of the end of the main beam 1 close to the telescopic beam 2.

[0020] A fixed nylon guide strip 13 is fixedly connected to the upper surface of the main beam 1, and a dynamic nylon guide strip 17 is provided on the upper surface of the telescopic beam 2. The fixed nylon guide strip 13 and the dynamic nylon guide strip 17 are used to guide the chain 18 when it extends or shortens.

[0021] Chains 18 are meshed on the first sprocket 4, the second sprocket 5, the telescopic sprocket 7, the tension sprocket 8, and the third sprocket 6. The inner sidewall of the chain 18 is sequentially meshed with the first sprocket 4, the tension sprocket 8, the third sprocket 6, and the second sprocket 5, while the outer sidewall of the chain 18 is sequentially meshed with the second sprocket 5 and the telescopic sprocket 7. The second sprocket 5 is located between the tension sprocket 8 and the third sprocket 6, and the telescopic sprocket 7 is located between the first sprocket 4 and the second sprocket 5.

[0022] The lead screw 3 is threaded with an adjusting nut 1401. A flange 21 is fixedly connected to one side of the adjusting nut 1401. A bearing bracket 19 is fixedly connected to the flange 21. The bearing bracket 19 is fixedly connected to the telescopic beam 2. The symmetrically arranged main beam 1 has an upper cover plate 15 fixedly installed on the upper surface of the opposite side. The symmetrically arranged main beam 1 has a support plate 16 fixedly installed on the opposite side for limiting the chain 18.

[0023] By simultaneously activating the first motors 10 on both sides, the first motors 10 control the lead screw 3 to rotate. The rotation of the lead screw 3 drives the adjusting nut 1401 to move forward or backward. The movement of the adjusting nut 1401 drives the flange 21 to move forward or backward. The movement of the flange 21 drives the bearing bracket 19 to move forward or backward. The movement of the bearing bracket 19 drives the telescopic beam 2 to move forward or backward. The forward or backward movement of the telescopic beam 2 simultaneously drives the first sprocket 4 and the telescopic sprocket 7 to move forward or backward. This achieves free extension and retraction of the conveyor length. During logistics loading and unloading, the length of the truck bed varies, and the telescopic conveyor can flexibly match and perfectly connect with the production line. It can quickly adjust the conveying distance according to changes in process layout. When not in operation, it retracts to the shortest state to reduce space occupation, improve work efficiency, and reduce the cost of manual handling. Compared with fixed conveyors and combinations of multiple transfer devices, it saves equipment purchase and maintenance costs and can be adapted to various occasions.

[0024] Please see Figure 1 and Figure 5 As shown, a conveyor shaft 11 is provided between the symmetrically arranged main beams 1. The two ends of the conveyor shaft 11 are rotatably connected to the third sprocket 6. One end of the conveyor shaft 11 passes through the main beam 1 and is connected to the output end of the second motor 1101. A connecting block 1201 is rotatably connected to the conveyor shaft 11 and is fixedly connected to the rear beam 12. Photoelectric accessories 20 are installed above the pallets 16. The photoelectric accessories 20 are used to detect the extension and retraction of the conveyed material.

[0025] By starting the second motor 1101, the second motor 1101 drives the conveyor shaft 11 to rotate, the rotation of the conveyor shaft 11 drives the third sprockets 6 at both ends to rotate, and the third sprockets 6 drive the chain 18 to drive the transmission, thereby realizing the transportation of goods.

[0026] Working principle: First, the length of the telescopic beam 2 is adjusted according to the length of the truck bed: by starting the first motor 10, the first motor 10 drives the synchronous toothed belt 1001, which in turn drives the synchronous gear 1002 to rotate, which in turn drives the lead screw 3 to rotate; the rotation of the lead screw 3 drives the adjusting nut 1401 to move forward or backward, which in turn drives the flange 21 to move forward or backward, which in turn drives the bearing bracket 19 to move forward or backward, which in turn drives the telescopic beam 2 to move forward or backward; the movement of the telescopic beam 2 simultaneously drives the first sprocket 4 and the telescopic sprocket 7 to move forward or backward; thus, the length of the telescopic beam 2 is adjusted.

[0027] Then, by starting the second motor 1101, the second motor 1101 drives the conveyor shaft 11 to rotate, the rotation of the conveyor shaft 11 drives the third sprockets 6 at both ends to rotate, and the third sprockets 6 drive the chain 18 to drive, thereby realizing the transportation of goods.
