Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 3, the utility model provides an automatic straining device of belt feeder, a serial communication port, including belt main wheel 1, base plate 2 and belt lift wheel 3, belt main wheel 1 is connected with belt lift wheel 3 through the belt and is formed the belt pulley subassembly, and base plate 2 is connected with belt lift wheel 3 through actuating lever 4 and is formed belt straining device, and belt main wheel 1 is installed on base plate 2 through the installation nail.
The surface of the substrate 2 is provided with a groove 5, the inner wall of one side of the groove 5 is provided with a rack 6, a gear 7 is arranged in the groove 5, the gear 7 is meshed with the rack 6 and is connected with the belt lifting wheel 3 through a driving rod 4, wherein the driving rod 4 is fixedly connected with the gear 7, the driving rod 4 is rotatably connected with the belt lifting wheel 3, and the end part of the driving rod 4 is provided with a driving motor 8 (only the driving shaft of the driving motor is drawn in the figure).
The rack 6 is fixedly arranged on the inner wall of the groove 5, and rubber pads for improving the connection wedging degree are arranged at the joints of the rack 6 and the gear 7 in order to improve the fitting degree of the whole device.
In the time of practical use, driving motor 8 drives actuating lever 4 and rotates, because actuating lever 4 and gear 7 fixed connection, consequently, actuating lever 4 can drive gear 7 and rotate, again because gear 7 is connected with the meshing of rack 6, so can lead to gear 7 can upwards climb or descend on rack 6, drive and rotate belt lifting wheel 3 of being connected with actuating lever 4 and climb or descend, thereby finally make the belt on the belt lifting wheel 3 pulled tight or lax, thereby come the rate of tension of controlling whole belt pulley subassembly with this.
In addition, the size of the groove 5 needs to be matched with the gear 7, the gear 7 is limited not to be separated in the groove 5, and lubricating oil can be coated on the surface of the gear 7 to reduce the friction force with the inner wall of the groove 5 as the gear 7 needs to rotate in the groove 5.
As shown in fig. 1, one end of the driving rod 4, which is far away from the driving motor 8, penetrates through the substrate 2 to extend outwards and is rotatably connected with a graduated scale 9, when the gear 7 is driven by the driving rod 4 to lift, the graduated scale 9 connected with the driving rod 4 also lifts synchronously, at this time, a transverse belt is used as a reference object, and scales on the graduated scale 9 are observed in the lifting or descending process of the graduated scale 9, so that the lifting or descending height of the belt lifting wheel 3 is controlled, and further the tension force required to be adjusted is controlled.
And the graduated scale 9 which is rotationally connected with the driving rod 4 cannot rotate due to the factor of gravity because of the limitation of the limiting frame 10.
And finally, detecting whether the adjusted tension is proper or not by pressing the belt and observing the pressing amount of the belt. The pressing force is generally about 10kg, and if the belt is pressed down by about 10mm, the belt tension is considered to be appropriate. If the amount of rolling is too large, the belt tension is considered insufficient.
As shown in figure 2, the two ends of the belt lifting wheel 3 on the driving rod 4 are provided with clamping limiting blocks 11, so that the belt lifting wheel 3 hung on the belt is prevented from displacing in the horizontal direction, and the using effect of the device is prevented from being influenced.
In this embodiment, the driving motor can adopt a rare earth motor, because the quick adjustment ability of the rare earth motor can match the response of the rapid acceleration and deceleration control of the belt motor, namely, the belt tension can change when the belt motor is rapidly accelerated and decelerated, the tension detector or the belt speed detector arranged on the belt can immediately transmit the detection signal to the driving motor after acquiring the related detection signal, and adjust the action of the driving motor to match the change of the belt tension, thereby making the belt be in a better state all the time. The transmission of the sensing signal and the response of the driving motor are conventional processes in the prior art, and are not described herein again.
The above embodiments are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Various modifications and equivalents may be made to the disclosure by those skilled in the art within the spirit and scope of the disclosure, and such modifications and equivalents should also be considered as falling within the scope of the disclosure.
