[0011] Beneficial effects

[0012] This invention provides a tensioning device for a conveyor track. Compared with existing technologies, it has the following advantages:

[0013] (1) This utility model uses the force of the spring to push the push rod downward, and the push rod will push the second sprocket downward through the rotating frame. The second sprocket will push the chain downward, and push the slack part of the chain to tighten. It can effectively tighten the chain. And through the force of the spring, it will continue to push the continuously slack chain downward. The second sprocket will continue to push the chain to keep it in a taut state, thus ensuring the normal transmission of the chain.

[0014] (2) This utility model drives the second threaded sleeve to move upward by rotating the second threaded rod. The second threaded sleeve will drive the second sprocket on the push cylinder to move upward through the limiting plate. At the same time, the second threaded rod will drive the first threaded rod to rotate through the second bevel gear and the first bevel gear. The first threaded rod will drive the first threaded sleeve to move towards the middle, so that the first threaded sleeve will drive the first sprocket on the moving frame to move towards the middle through the sliding plate. This will cause the two first sprockets and the second sprocket to move towards the middle, which can effectively loosen the chain and make it easy to disassemble and maintain the chain.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a conveyor track tensioning device, including a conveyor frame body 1. Sliding grooves 2 are provided on both sides of the rear part of the inner cavity of the conveyor frame body 1. A sliding plate 3 is slidably connected inside the sliding groove 2. A movable frame 4 is fixedly connected to the front part of the sliding plate 3. A first sprocket 5 is rotatably connected to the front part of the movable frame 4. For detailed description, the first sprocket 5 is driven by an external driving mechanism. A chain 6 is connected between the surfaces of the two first sprockets 5. An adjustment mechanism 7 is provided at the rear of the conveyor frame body 1. A limiting groove 8 is provided at the rear of the inner cavity of the conveyor frame body 1, located between the two sliding grooves 2. A limiting plate 9 is slidably connected inside the limiting groove 8. A push cylinder 10 is fixedly connected to the front of the bottom of the limiting plate 9. A push rod 11 is slidably connected inside the push cylinder 10. A rotating frame 12 is fixedly connected to one end of the push rod 11. A second sprocket 13 adapted to the chain 6 is rotatably connected inside the rotating frame 12. A spring 14 is fixedly connected between the top of the inner cavity of the push cylinder 10 and the other end of the push rod 11.

[0021] Furthermore, to facilitate the movement of the two first sprockets 5 toward the center, the adjustment mechanism 7 includes a fixed frame 71, which is fixedly connected to the rear of the conveyor frame body 1. Fixed plates 72 are fixedly connected to both sides of the rear of the conveyor frame body 1. A first threaded rod 73 is rotatably connected to one side of the fixed plate 72 via a bearing. One end of the first threaded rod 73 passes through the fixed frame 71 and extends into the interior of the fixed frame 71. A first threaded sleeve 74 is threadedly connected to the surface of the first threaded rod 73. The top of the sliding plate 3 is fixedly connected to the first threaded sleeve 74.

[0022] Furthermore, in order to facilitate the upward movement of the chain 6, the top of the fixed frame 71 is rotatably connected to a second threaded rod 75 through an opening. One end of the second threaded rod 75 is fixedly connected to a handle, and a second threaded sleeve 78 is threadedly connected to the surface of the second threaded rod 75. The rear part of the limiting plate 9 is fixedly connected to the second threaded sleeve 78. A second bevel gear 77 is fixedly connected to the upper part of the surface of the second threaded rod 75, and a first bevel gear 76 that matches the second bevel gear 77 is fixedly connected to the end of the first threaded rod 73.

[0023] In use, the drive mechanism drives the first sprocket 5 to rotate, and the two first sprockets 5 drive the chain 6 to drive the transmission. The chain 6 drives the second sprocket 13 in the rotating frame 12 to rotate. At the same time, the spring 14 exerts a downward force, causing the push rod 11 to push the second sprocket 13 in the rotating frame 12 to move downward. The second sprocket 13 maintains a downward thrust, causing the second sprocket 13 to push the chain 6 downward to maintain tension.

[0024] When chain 6 needs to be disassembled and maintained, the second threaded rod 75 is rotated by turning the handle. The second threaded rod 75 will drive the second threaded sleeve 78 to move upward, so that the second threaded sleeve 78 drives the push cylinder 10 to move upward through the limit plate 9. The push cylinder 10 drives the second sprocket 13 to move upward through the push rod 11 and the rotating frame 12, so that the second sprocket 13 no longer pushes the chain 6. At the same time, the rotation of the second threaded rod 75 will drive the second bevel gear 77 to rotate. The second bevel gear 77 will drive the two first threaded rods 73 to rotate through the two first bevel gears 76. The first threaded rod 73 will drive the first threaded sleeve 74 to move towards the middle. The first threaded sleeve 74 will drive the first sprocket 5 on the moving frame 4 to move towards the middle through the sliding plate 3, so that the two first sprockets 5 move towards the middle at the same time. By moving the two first sprockets 5 and the second sprocket 13 towards the middle at the same time, the chain 6 is no longer tensioned. The loose chain 6 can be removed from the two first sprockets 5 for maintenance.
