DETAILED DESCRIPTION

[0018] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0019] Example

[0020] See also Figure 1-Figure 5The utility model is a tensioning wheel device for a flat chain conveyor, comprising a tensioning sprocket 1, a mounting plate 2 provided with four sets of bolt mounting holes 3, two sets of guide rails 4 symmetrically fixedly connected at the front end of the mounting plate 2, two sets of guide rails 4 are provided with T-shaped slide grooves, two sets of guide rails 4 are slidably mounted with sliding frames 5 through the cooperation of the T-shaped slide grooves, the inner walls of the left and right sides of the sliding frame 5 are provided with limiting slide grooves 6, the sliding frame 5 is provided with a limiting slider 7 through the cooperation of the limiting slide grooves 6, and the limiting slider 7 is provided with a bearing A connecting shaft 8 is rotatably installed, and a tensioning sprocket 1 is fixedly sleeved on the connecting shaft 8. A threaded hole is provided at the bottom of the sliding frame 5. An adjusting screw rod 9 is installed at the bottom of the sliding frame 5 through a matching screw of the threaded hole, and the top of the adjusting screw rod 9 is rotatably connected to the bottom end of the limit slider 7. A knob 10 is fixedly sleeved at the bottom end of the adjusting screw rod 9. A fixing plate 11 is fixedly connected to the right side of the front end of the mounting plate 2. Both ends of the fixing plate 11 are respectively connected to the inner sides of the two sets of guide rails 4. The lower side of the left end of the fixing plate 11 and the middle of the right end of the limit slider 7 are fixedly provided. There are hinged seats 12, and a transmission strip plate 13 is hinged between the two sets of hinged seats 12; when in use, the mounting plate 2 is installed to the appropriate position of the flat chain conveyor frame through the cooperation of the bolts and the bolt mounting holes 3, so that the chain is bypassed from the tensioning sprocket 1. When adjusting the tension, the adjusting screw rod 9 is rotated by the knob 10 to make the adjusting screw rod 9 drive the limit slider 7 to slide downward. When the limit slider 7 moves downward, the limit slider 7 drives the transmission strip plate 13 to swing downward through the hinged seat 12, so that the transmission The movable plate 13 pushes the sliding frame 5 to slide leftward along the guide rail 4 through the limit slider 7, so that the limit slider 7 and the connecting shaft 8 drive the tensioning sprocket 1 to move to the lower left, and then the chain is tensioned by the tensioning sprocket 1. Conversely, if the limit slider 7 is pushed to slide upward by adjusting the screw rod 9, the tensioning sprocket 1 will move to the upper right, loosening the chain and adjusting the chain tension. This makes it easy to adjust the position of the tensioning wheel, making it more convenient to adjust the chain tension and improving ease of use.

[0021] A lock nut 14 is threadedly mounted on the adjusting screw rod 9. By setting the lock nut 14, when the chain tension is adjusted to an appropriate level by rotating the adjusting screw rod 9 to adjust the position of the limit slider 7, the lock nut 14 is tightened to lock the adjusting screw rod 9, thereby preventing the adjusting screw rod 9 from rotating on its own and ensuring that the position of the limit slider 7 remains unchanged.

[0023] The four groups of bolt mounting holes 3 are all configured as countersunk holes. By adopting the countersunk hole design, when the mounting plate 2 is fixed with bolts, the bolt cap can be prevented from being higher than the front end of the mounting plate 2, thereby preventing the bolt cap from protruding too much.

[0024] The adjusting screw rod 9 is made of stainless steel; by adopting stainless steel, the strength of the adjusting screw rod 9 can be improved and the surface of the adjusting screw rod 9 can be prevented from rusting.

[0025] The utility model is a tensioning wheel device for a flat chain conveyor. Its working principle is that when in use, the mounting plate 2 is installed to the appropriate position of the flat chain conveyor frame through the cooperation of the bolts and the bolt mounting holes 3, so that the chain is bypassed from the tensioning sprocket 1. When adjusting the tension, the adjusting screw rod 9 is rotated by the knob 10 to make the adjusting screw rod 9 drive the limit slider 7 to slide downward. When the limit slider 7 moves downward, the limit slider 7 drives the transmission strip plate 13 to swing downward through the hinge seat 12, so that the transmission strip plate 13 passes through the limit slider 7. The sliding frame 5 is pushed to slide leftward along the guide rail 4, so that the limit slider 7 and the connecting shaft 8 drive the tensioning sprocket 1 to move to the lower left, and then the chain is tensioned by the tensioning sprocket 1. Conversely, if the limit slider 7 is pushed upward to slide by adjusting the screw rod 9, the tensioning sprocket 1 is moved to the upper right, so that the chain becomes loose and the chain tension is adjusted. After the chain tension is adjusted, the lock nut 14 is tightened so that the lock nut 14 locks the adjusting screw rod 9, thereby preventing the adjusting screw rod 9 from rotating by itself and ensuring that the position of the limit slider 7 remains unchanged.

[0026] The utility model is a tensioning wheel device for a flat chain conveyor, and its installation method, connection method or setting method are all common mechanical methods, and can be implemented as long as it can achieve its beneficial effects; technicians in this industry only need to install and operate it according to the accompanying instruction manual.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
