Technical Field

[0001] This utility model belongs to the field of conveyor technology, specifically relating to a tensioning device for adaptive tension control of a conveyor. Background Technology

[0002] A conveyor is a material handling machine used to continuously transport materials along a certain route. It plays an extremely important role in modern industry and logistics.

[0003] Belt conveyors are a type of conveyor, but most belt conveyors use drive rollers at both ends to tension the conveyor belt. When conveying items of varying weights, the tension on the conveyor belt will also vary. If tensioning is achieved using fixed drive rollers, it may cause friction or loosening of the conveyor belt, thus accelerating wear, affecting its service life, and causing inconvenience in the use of the conveyor.

[0004] Therefore, this invention provides a tensioning device for adaptive tension control of a conveyor to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a tensioning device for adaptive tension control of a conveyor, which aims to solve the problem that in the existing belt conveyor, when conveying items of different weights, the tension on the conveyor belt will also be different. If tensioning is performed by a fixed drive roller, the conveyor belt may experience friction or loosening, thereby aggravating the wear of the conveyor belt, affecting the service life of the conveyor belt, and causing inconvenience to the use of the conveyor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tensioning device for adaptive tension control of a conveyor, comprising a conveyor body, a conveyor belt sleeved on the outer surface of the conveyor body, the inner surface of the bottom end of the conveyor belt contacting the outer surface of an adjusting roller, connecting blocks rotatably connected to both ends of the adjusting roller, mounting blocks connected at the middle of both ends of the conveyor body, a through moving groove formed on one end surface of the mounting block, bearings embedded on both ends of the moving groove, a screw connected between the two bearings, one end of the screw extending into the mounting block and fixedly connected to the output end of a motor, and a moving block throughly connected to one end of the screw, a protrusion connected to one end surface of the moving block, a sliding groove formed on the end surface of the protrusion away from the moving block, a connecting block connected to the inner surface of the sliding groove, a sliding rod throughly connected to the bottom surface of the protrusion, the other end of the sliding rod slidably connected to the connecting block, and a spring wrapped around the outer wall of the sliding rod.

[0007] In a preferred embodiment of the tensioning device for adaptive tension control of a conveyor according to this utility model, the moving block is slidably connected to the mounting block via a moving groove, and the moving block is threadedly connected to the screw.

[0008] As a preferred embodiment of the tensioning device for adaptive tension control of a conveyor according to this utility model, the motor is connected to the top surface of the mounting block, and the two side surfaces of the mounting block are connected to fixing blocks. The motor is electrically connected to an external power supply through a control switch.

[0009] As a preferred embodiment of the tensioning device for adaptive tension control of a conveyor according to this utility model, the connecting block is slidably connected to the protrusion through a groove, and the connecting block forms an elastic structure inside the groove through a slide rod and a spring.

[0010] As a preferred embodiment of the tensioning device for adaptive tension control of a conveyor according to this utility model, a rotating block is connected to the bottom surface of the slide bar, and an arc-shaped groove is formed in a ring array on the outer surface of the rotating block.

[0011] As a preferred embodiment of the tensioning device for adaptive tension control of a conveyor according to this utility model, the top surface of the slide bar is connected to a threaded column, one end of the threaded column is threadedly connected to a threaded groove, and the threaded groove is formed on the top surface of the inner side of the slide groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes the coordinated operation of an adjusting roller, connecting block, mounting block, screw, moving block, protrusion, slide bar, and spring. By starting the motor, the motor's output drives the screw, which in turn moves the adjusting roller connected to the protrusion via the moving block. This tensions the conveyor belt to a preset state. When the items being conveyed on the belt change, the conveyor belt moves the adjusting roller, causing the connecting blocks at both ends of the adjusting roller to elastically extend and retract via the slide bar and spring. This allows the adjusting roller to adaptively adjust the tension of the conveyor belt based on the tension, maintaining the belt tension within a reasonable range, preventing slippage, and ensuring the conveyor belt's service life.

[0014] This invention utilizes the interplay of a rotating block, a threaded column, and a threaded groove. By rotating the rotating block, the threaded column can rotate within the threaded groove via a sliding rod, allowing the threaded column to separate from the groove. Pulling the sliding rod then separates it from the protrusion, enabling maintenance and replacement of the spring within the groove, thus ensuring the spring's effectiveness.

[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. 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.

[0022] Please see Figures 1-4 This utility model provides the following technical solution: a tensioning device for adaptive tension control of a conveyor, including a conveyor body 1, a conveyor belt 2 sleeved on the outer surface of the conveyor body 1, the inner surface of the bottom end of the conveyor belt 2 in contact with the outer surface of the adjusting roller 3, connecting blocks 4 rotatably connected to both ends of the adjusting roller 3, mounting blocks 5 connected at the middle position of both ends of the conveyor body 1, a through moving groove 6 opened on one end surface of the mounting block 5, bearings 7 embedded on both ends of the moving groove 6, a screw 8 connected between the two bearings 7, one end of the screw 8 extending into the mounting block 5 and fixedly connected to the output end of the motor 9, and a moving block 10 through connected to one end of the screw 8, a protrusion 11 connected to one end surface of the moving block 10, a sliding groove 12 opened on the end surface of the protrusion 11 away from the moving block 10, a connecting block 4 connected to the inner surface of the sliding groove 12, a sliding rod 14 through connected to the bottom surface of the protrusion 11, the other end of the sliding rod 14 through slidingly connected to the connecting block 4, and a spring 15 wrapped around the outer wall of the sliding rod 14.

[0023] Preferably, the movable block 10 is slidably connected to the mounting block 5 via the movable groove 6, and the movable block 10 is threadedly connected to the screw 8.

[0024] In practical use, by starting the motor 9, the output end of the motor 9 can drive the screw 8 to rotate in the bearing 7. At this time, the moving block 10 on the screw 8 will move along the screw 8 in the moving groove 6 on the mounting block 5, so the moving block 10 will drive the protrusion 11 to move.

[0025] Preferably, the motor 9 is connected to the top surface of the mounting block 5, and the mounting block 5 has fixing blocks 13 connected to both sides of the mounting block 5. The motor 9 is electrically connected to an external power source through a control switch.

[0026] In practical use, motor 9 has an automatic mounting base. The operator can fix motor 9 to mounting block 5 by passing bolts through the mounting base on motor 9. Then, the operator can screw bolts through fixing block 13 into the frame on the conveyor body 1 to fix the position of mounting block 5 on the frame on the conveyor body 1. The two motors 9 can be connected in parallel to the same control switch, so that the two motors 9 can be controlled at the same time through one control switch, so that the two motors 9 can run synchronously.

[0027] Preferably, the connecting block 4 is slidably connected to the protrusion 11 through the groove 12, and the connecting block 4 forms an elastic structure inside the groove 12 through the slide rod 14 and the spring 15.

[0028] In practical use, one end of the spring 15 contacts the connecting block 4, and the other end contacts the inner surface of the slide groove 12. When the connecting block 4 slides in the slide groove 12, the connecting block 4 will also move along the slide rod 14, so that the connecting block 4 can squeeze the spring 15 through the slide rod 14, and the connecting block 4 can elastically stretch and move in the slide groove 12.

[0029] Preferably, the bottom surface of the slide bar 14 is connected to a rotating block 16, and the outer surface of the rotating block 16 is provided with arc-shaped grooves in a ring array.

[0030] In practical use, the arc-shaped groove on the outer surface of the rotating block 16 can increase the friction of the operator's hand, making it easier for the operator to turn the rotating block 16.

[0031] Preferably, the top surface of the slide bar 14 is connected to a threaded post 17, one end of which is threadedly connected to a threaded groove 18, which is formed on the top surface of the inner side of the slide groove 12.

[0032] In practical use, when the threaded post 17 on the slide rod 14 is separated from the threaded groove 18, the slide rod 14 can be removed from the protrusion 11. At this time, the operator can separate and replace the spring 15, and then put the spring 15 back into the slide groove 12. Then, the slide rod 14 passes through the connecting block 4 and the spring 15, so that the threaded post 17 at the top of the slide rod 14 is screwed into the threaded groove 18. At this time, the position of the slide rod 14 can be fixed on the protrusion 11, so that the slide rod 14 can restrict the spring 15 in the slide groove 12.

[0033] Working principle: When using the adaptive tension control tensioning device of this conveyor, after moving the conveyor body 1 to the designated position, the tension of the conveyor belt 2 on the conveyor body 1 can be adjusted first. Then, the motor 9 is started by switching on the motor, causing the output end of the motor 9 to drive the screw 8 to rotate in the bearing 7. The moving block 10 on the screw 8 will then move along the moving groove 6 on the mounting block 5. This moving block 10 will then drive the connected protrusions 11 to move, causing the two protrusions 11 to drive the adjusting roller 3 to move through the connecting block 4. This allows the adjusting roller 3 to apply tension to the conveyor belt 2 until it is tensioned to the preset state. When the drive roller in the conveyor body 1 drives the conveyor belt 2 to convey materials, if the weight of the material on the conveyor belt 2 changes, the tension on the conveyor belt 2 will change. This will cause the conveyor belt 2 to move, displacing the adjusting roller 3, causing the connecting blocks 4 at both ends of the adjusting roller 3 to move along the protrusions. The connecting block 4 slides along the slide bar 14 in the groove 12 on the 11. At this time, the connecting block 4 will move elastically in the groove 12 through the slide bar 14 and the spring 15. The reverse force generated by the elastic deformation of the spring 15 can make the position of the adjusting roller 3 adaptively fine-tune, continuously apply appropriate tension to the conveyor belt 2, and keep the tension of the conveyor belt 2 stably within a reasonable range. This avoids the problem of excessive tension causing wear of the conveyor belt 2, or insufficient tension causing slippage or deviation of the conveyor belt 2, thereby ensuring the service life of the conveyor belt 2. Secondly, when the spring 15 is severely aged and its performance is poor, the operator can turn the rotating block 16 at the bottom of the slide bar 14. At this time, the threaded post 17 at the top of the slide bar 14 will rotate in the threaded groove 18, so that the threaded post 17 can be separated from the threaded groove 18. Then, by pulling the slide bar 14, the slide bar 14 can be separated from the protrusion 11. At this time, the spring 15 in the groove 12 can be taken out for maintenance and replacement, thereby ensuring the performance of the spring 15.

[0034] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
