Technical Field

[0001] This utility model belongs to the field of roller machine technology, specifically relating to a telescopic roller coupling machine. Background Technology

[0002] A stacker roller conveyor is a conveying device that moves items forward by relying on the friction between rotating rollers and the items. It typically consists of rollers, a frame, supports, and a drive unit. The rollers are the core component of the conveyor and are usually made of metal or plastic, with the surface possibly coated with wear-resistant materials to increase service life. Rollers can be made of steel, ceramic, etc. In the design of stacker-operated high-density warehouses, some large warehouse areas require higher fire safety standards, necessitating the installation of fire doors between large warehouse areas to prevent potential accidents.

[0003] When a fire emergency occurs, the fire door may encounter the roller conveyor during the lowering process, which may cause interference and prevent the fire door from being fully lowered and opened. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides a telescopic roller coupling machine, which solves the problem of interference caused when fire doors encounter roller conveyors during the lowering process.

A slide rail is fixedly connected to the top of the support frame two, and a slider is slidably installed inside the slide rail. A platform two is rotatably connected to one side of the slider, and a roller is rotatably connected to one side of the platform two. A motor two is fixedly installed on the lower surface of the platform two, and a sprocket five is fixedly connected to the output end of the motor two. A conveying assembly is installed on the upper surface of the platform two, and a connector is fixedly connected to the lower surface of the platform two. A chain one is sleeved on the surface of sprocket one and sprocket two, and a chain two is sleeved on the surface of sprocket three and sprocket four.

[0006] Preferably, the conveying assembly includes a support base two, a shaft two, a sprocket six, a sprocket seven, a support member, a roller and a sprocket eight. The sprocket six is ​​located on the surface of the shaft two and is in the same vertical plane as the sprocket five. The sprocket seven is located at both ends of the shaft two.

[0008] Preferably, the slider and roller are both located inside the slide rail, and the slider and roller are arranged in a horizontal array.

[0009] Preferably, the two ends of the second chain are movably connected to two connectors respectively.

[0010] Preferably, a limit baffle is fixedly connected to the lower surface of the second platform.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This telescopic roller coupling machine utilizes a motor to drive a sprocket, which in turn drives a chain to rotate a second sprocket. Since the shaft is integrated with sprockets two and three, it can rotate within a support base. The support base provides support for both shafts. A second chain, fitted onto sprocket three and two fourth sprockets, extends laterally through the fourth sprockets, with each end connected to a connector. This provides tension, and the laterally extended portions of the chain maintain a horizontal position. When sprocket three rotates, it drives the second chain, which in turn drives the fourth sprockets. Because the fourth sprockets are fixed by bearings, the second chain generates power, causing the platform two to move along the slide rail via sliders and rollers. This movement facilitates the displacement of the conveying components, enabling the platform two to extend and retract, thus avoiding obstruction of the lowering and unfolding of the fire door.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6This utility model provides the following technical solution: a telescopic roller coupling machine, including a support frame 1 and a support frame 2. A platform 3 is fixedly installed on the upper surface of the support frame 1, and a motor 4 is fixedly installed on the upper surface of the platform 3. A sprocket 5 is fixedly connected to the output end of the motor 4. A support base 6 is fixedly connected to the upper surface of the platform 4. A shaft 7 is rotatably installed inside the support base 6. A sprocket 8 is fixedly connected to the surface of the shaft 7. Sprockets 9 are fixedly connected to both ends of the shaft 7. A fixing plate 10 is fixedly connected to the inner side of the support frame 2. A bearing 11 is fixedly connected inside the fixing plate 10. One side of the support frame 2 is fixedly connected to a sprocket 12. The top of the support frame 2 is fixedly connected to a slide rail 13. The slide rail 13 is slidably installed with a slider 14. One side of the slider 14 is rotatably connected to a platform 2 15. One side of the platform 2 15 is rotatably connected to a roller 16. The lower surface of the platform 2 15 is fixedly installed with a motor 2 17. The output end of the motor 2 17 is fixedly connected to a sprocket 5 18. The upper surface of the platform 2 15 is equipped with a conveying assembly 19. The lower surface of the platform 2 15 is fixedly connected with a connector 20. The surfaces of the sprocket 1 5 and the sprocket 2 8 are sleeved with a chain 1 21. The surfaces of the sprocket 3 9 and the sprocket 4 12 are sleeved with a chain 2 22.

[0023] In this embodiment, the motor 4 facilitates the rotation of sprocket 5, which in turn drives sprocket 8 to rotate via chain 21. Since shaft 7 is integrated with sprocket 8 and sprocket 9, shaft 7 can rotate within support base 6, which supports shaft 7. Chain 22 is provided, fitted onto sprocket 9 and two sprockets 12. Chain 22 extends to both sides via the two sprockets 12, with each end connected to a connector 20. Therefore, chain 2... Chain 22 can have a certain tension. The parts of chain 22 extending to both sides can maintain a certain horizontal position. Therefore, when chain 3 9 rotates, it can drive chain 22. At the same time, chain 22 drives chain 4 12 to roll. Since chain 4 12 cannot be displaced by the limit of bearing 11, chain 22 will generate power, which can drive platform 2 15 to move horizontally along slide rail 13 through slider 14 and roller 16. This is conducive to driving the displacement of the conveying component, so that platform 2 15 can achieve the effect of extension and retraction, and avoids hindering the lowering and unfolding of the fire door.

[0024] Specifically, the conveying assembly 19 includes a support base 191, a shaft 192, a sprocket 193, a sprocket 194, a support member 195, a roller 196, and a sprocket 197. The sprocket 193 is located on the surface of the shaft 192 and is on the same vertical plane as the sprocket 18, which facilitates the connection of the chain 23. The sprocket 194 is located at both ends of the shaft 192. The roller 196 is rotatably connected to the support member 195, and the sprocket 197 is located on one side of the roller 196. The support base 191 facilitates the rolling of the shaft 192, and the sprocket 197 facilitates the rotation of the roller 196.

[0025] Specifically, chain 23 is sleeved on the surface of sprocket 5 18 and sprocket 6 193, chain 24 is sleeved on the surface of sprocket 7 194 and sprocket 8 197, and chain 25 is sleeved on the surface of sprocket 8 197. Motor 2 17 can drive sprocket 5 18 to rotate, and sprocket 5 18 drives sprocket 6 193 to rotate through chain 3 23. Sprocket 6 193 is integrated with shaft 2 192 and sprocket 7 194, so the rotation of sprocket 7 194 can drive sprocket 8 197 to rotate through chain 4 24, and sprocket 8 197 is linked through chain 5 25, which is beneficial to the operation of roller 196.

[0026] Specifically, both slider 14 and roller 16 are located inside slide rail 13, and slider 14 and roller 16 are arranged in a horizontal array. The multiple arrays of slider 14 and roller 16 help to improve the stability of platform 2 15.

[0027] Specifically, the two ends of chain 22 are movably connected to two connectors 20, which helps chain 22 to have tension.

[0028] Specifically, a limiting baffle 26 is fixedly connected to the lower surface of platform 2 15. The setting of the limiting baffle 26 helps to restrict the extension of chain 2 22, so that it can be located below platform 2 15 and contact platform 2 15.

[0029] The working principle or usage process of this utility model is as follows: When in use, starting motor 2 17 drives sprocket 5 18 to rotate. Sprocket 5 18 drives sprocket 6 193 to rotate via chain 3 23. Sprocket 6 193 is integrated with shaft 2 192 and sprocket 7 194. Thus, the rotation of sprocket 7 194 drives sprocket 8 197 to rotate via chain 4 24. Sprocket 8 197 is linked via chain 5 25, which is beneficial to the operation of roller 196. When it is necessary to avoid fire doors, motor 1 4 can be started to drive sprocket 1 5 to rotate. Thus, sprocket 1 5 drives sprocket 2 8 to roll via chain 1 21. Since shaft 1 7 is integrated with sprocket 2 8 and sprocket 3 9, shaft 1 7 can rotate within support base 1 6. Support base 1 6 supports shaft 1 7. Chain 2 22 is sleeved on sprocket 3 9 and two sprockets 4 12. Chain 2 22 is connected to the two sprockets. Chain 12 extends to both sides, with two connectors 20 at each end. Therefore, chain 22 can have a certain tension. The extended parts of chain 22 can maintain a certain horizontal position. Thus, when sprocket 3 rotates, it can drive chain 22. At the same time, chain 22 drives sprocket 4 to roll. The setting of the limiting baffle 26 helps to restrict the extended part of chain 22, so that it can be located below platform 2 and contact platform 2. Since sprocket 4 cannot be displaced by the limiting of bearing 11, chain 22 will generate power, which can drive platform 2 to move along slide rail 13 through slider 14 and roller 16. This helps to drive the displacement of the conveying component, so that platform 2 can achieve the effect of extension and retraction, avoiding obstruction of the lowering and unfolding of the fire door. All electrical equipment in this device is externally powered and controlled by the matching control switch to operate and shut down.
