Description

Technical Field

[0001] The utility model relates to packaging equipment, in particular to a telescopic conveyor belt. Background Art

[0002] Conveyor belts are an indispensable component of packaging equipment, primarily used to transport various materials or packaging substrates. Traditional conveyor belts have fixed rollers, making their overall position and length impossible to adjust. In practice, if the interior of the equipment needs to be inspected or repaired, the conveyor belt must be dismantled. Consequently, some retractable conveyor belt structures have emerged on the market, but these are generally complex, making production, assembly, and subsequent maintenance very cumbersome.

[0010] A telescopic conveyor belt of the above technical solution sets the position characteristics of the power roller, the first winding roller and the second winding roller, and the inner and outer sides of the conveyor belt are respectively wound around the first and second winding rollers. When the movable frame moves, the length of the conveyor belt between the second winding roller and the power shaft can be changed, thereby realizing the belt replenishment when the conveyor belt is extended and the belt storage when the conveyor belt is retracted, and the movement and feeding of the conveyor belt itself will not be affected during and after the adjustment.

[0013] Figure 2 This is a structural diagram of the utility model when the movable frame drives the conveyor belt to retract;

[0015] As shown in the figure, the utility model discloses a telescopic conveyor belt, which has a frame, and a drive motor 6 is provided on the frame. The output end of the drive motor 6 is connected to the power roller 5 rotatably provided on the frame. Specifically, the output end of the drive motor 6 is connected to the first synchronous wheel 14, and the first synchronous wheel 14 is connected to the second synchronous wheel 13 through a synchronous belt, and the second synchronous wheel 13 is connected to the power roller 5. The inner side of the conveyor belt 2 passes around the power roller 5, and a movable frame 3 is movably provided on the frame. The movable frame 3 is connected to the movable drive assembly. Specifically, the movable drive assembly includes an electric screw 12, and the movable rod of the electric screw 12 is connected to the movable frame 3. Of course, in addition to using an electric screw, common linear drive structures such as a cylinder, a rack and pinion structure, and a synchronous belt transmission structure can also be used to drive the movable frame 3 to move. The front end of the mobile frame 3 is provided with a first winding roller 1, and the rear end of the mobile frame 3 is provided with a second winding roller 4. The inner side of the conveyor belt 2 passes around the first winding roller 1, and the outer side of the conveyor belt 2 passes around the second winding roller 4. A positioning roller group is provided on the frame, and the inner side of the conveyor belt passes around the positioning roller group. In this embodiment, the positioning roller group includes a first positioning roller 11 and a second positioning roller 10. The first positioning roller 11 is provided to correspond to the rear side of the first winding roller 1, and the second positioning roller 10 is provided to correspond to the rear side of the power roller 5. This can realize the rear positioning winding of the conveyor belt, and the structure is very simple. Within the moving path of the mobile frame 3, the power roller 5 is horizontally located between the first winding roller 1 and the second winding roller 4. Furthermore, a tensioning seat 9 is movably provided on the frame, and a locking assembly is provided corresponding to the tensioning seat 9. The locking assembly includes a fastener, which can pass through the strip groove 8 on the tensioning seat 9 and be screwed with the threaded hole on the frame to lock the tensioning seat 9. By loosening the fastener, the tensioning seat 9 is driven to move along the strip groove 8, and the position of the tensioning seat 9 can be adjusted. A tensioning roller 7 is rotatably provided on the tensioning seat 9, and the tensioning roller 7 presses the outer side of the conveyor belt 2 to achieve the tensioning effect on the conveyor belt 2.

[0016] The working principle of the present utility model is: by controlling the drive motor 6 to start, the synchronous belt transmission group drives the power roller 5 to rotate, and the conveyor belt 2 can be driven to transport materials. When it is necessary to control the conveyor belt 2 to extend and lengthen, the electric screw 12 is controlled to drive the movable frame 3 to move outward, and the first and second winding rollers are driven to move outward synchronously. At this time, the conveyor belt portion between the second winding roller 4 and the power roller 5 is transformed into the first and second winding rollers and the first winding roller 1 and the first positioning roller 11, so as to realize the outward movement and lengthening of the conveyor belt 2. When it is necessary to control the conveyor belt 2 to shorten, the electric screw 12 is controlled to drive the movable frame 3 to move inward, and the first and second winding rollers are driven to move inward synchronously. At this time, the inward-retracted conveyor belt portion is again transformed into the space between the second winding roller 4 and the power roller 5, and because the movable frame 3 is retracted at this time, space can be made on the equipment to facilitate workers to check or repair the interior.

[0017] The structure of the present invention sets the position characteristics of the power roller, the first winding roller and the second winding roller, and the inner and outer sides of the conveyor belt are respectively wound around the first and second winding rollers. When the movable frame moves, the length of the conveyor belt between the second winding roller and the power shaft can be changed, thereby realizing the belt body replenishment when the conveyor belt is extended and the belt storage when the conveyor belt is retracted, and the movement and feeding of the conveyor belt itself will not be affected during and after the adjustment. The overall structure is very simple, and production assembly and subsequent maintenance operations can be conveniently carried out.
