In a preferred embodiment of the control method, the step of "selectively correcting the positions of the first pulley and the second pulley based on the detection results of the rotational position of the first pulley and the rotational position of the second pulley" specifically includes: selectively correcting the positions of the first pulley and the second pulley according to the rotational position of the first pulley if only the rotational position of the first pulley is detected; selectively correcting the positions of the first pulley and the second pulley according to the rotational position of the second pulley if only the rotational position of the second pulley is detected; if the rotational position of the first pulley and the rotational position of the second pulley are detected at the same time, the positions of the first pulley and the second pulley are selectively corrected according to the rotational position of any one of the first pulley and the second pulley.
As can be understood by those skilled in the art, in the preferred embodiment of the present invention, the detection component can detect the rotational positions of the first pulley and the second pulley, so that the positions of the first pulley and the second pulley can be corrected in time when the first pulley and the second pulley are deviated from each other in rotation, thereby avoiding the occurrence of inaccurate rotational positions and ensuring the normal use of the pulley device.

Based on the problem that the prior belt wheel device has poor use effect or even cannot be normally used due to deviation of the rotation of the belt wheel in the rotation process of the belt wheel, the invention provides a belt wheel device, a shoe washing machine and a control method for the belt wheel device, aiming at correcting the positions of a first belt wheel and a second belt wheel in time when the first belt wheel and the second belt wheel rotate and deviate, avoiding the condition of inaccurate rotation position and further ensuring the normal use of the belt wheel device.
As shown in fig. 1, the shoe washing machine of the present invention comprises a pulley device, a driving member and a mounting assembly (not shown in the figure), wherein the pulley device comprises a fixed member 1, a first pulley 2 and a second pulley 3 mounted on the fixed member 1, the first pulley 2 and the second pulley 3 are connected by a transmission belt 4, the driving member comprises a driving motor and a driving pulley 5 connected to an output shaft of the driving motor, the driving pulley 5 is disposed on the fixed member 1, the first pulley 2 and the second pulley 3 are both driven pulleys, and the driving pulley 5 and the first pulley 2 and the second pulley 3 are both connected by the transmission belt 4, the mounting assembly comprises a first mounting bracket disposed on the first pulley 2 and a second mounting bracket disposed on the second pulley 3, the first mounting bracket and the second mounting bracket are respectively mounted with a shoe, the driving pulley 5 can be driven to rotate by the driving motor, the driving pulley 5 can drive the first pulley 2 and the second pulley 3 to synchronously rotate in the rotating process, so that the first mounting frame and the second mounting frame synchronously rotate, and the shoes on the first mounting frame and the shoes on the second mounting frame are brushed conveniently. In addition, the pulley device of the present invention further includes a detection assembly including a first member to be sensed provided on the first pulley 2, a second member to be sensed provided on the second pulley 3, and a first sensing member and a second sensing member provided on the fixed member 1, the first sensing member being for sensing the first member to be sensed in a first angular range to detect the position of the first pulley 2, and the second sensing member being for sensing the second member to be sensed in a second angular range to detect the position of the second pulley 3. The fixing member 1 may be a fixing plate, a fixing bracket, or a fixing seat, and a person skilled in the art may flexibly set the specific structure of the fixing member 1 in practical applications as long as the driving pulley 5, the first pulley 2, and the second pulley 3 can be installed through the fixing member 1. In addition, in the present invention, the first angle range and the second angle range can be obtained according to a test before the shoe washing machine leaves the factory, that is, the deviation ranges of the first belt pulley 2 and the second belt pulley 3 are measured in advance before the shoe washing machine leaves the factory, and then the first sensing member can sense the position of the first sensed member in the first angle range. In the present invention, the first sensing member may be the first hall sensor 6, the first sensed member may be the first magnet 7, the second sensing member may be the second hall sensor 8, and the second sensed member may be the second magnet 9. Of course, the first sensing member and the second sensing member may also be infrared sensors, the first sensed member and the second sensed member may also be bumps, and the positions of the bumps can be sensed by the infrared sensors, so as to determine the rotation positions of the first pulley 2 and the second pulley 3. The following describes the technical solution of the present invention in detail by taking the first sensing member as the first hall sensor 6, the first sensed member as the first magnet 7, the second sensing member as the second hall sensor 8, and the second sensed member as the second magnet 9 as examples.
Preferably, as shown in fig. 1, the first hall sensor 6 is disposed near the edge of the first pulley 2, and the second hall sensor 8 is disposed near the edge of the second pulley 3, that is, both the first hall sensor 6 and the second hall sensor 8 are disposed on the fixing member 1, and in order for the first hall sensor 6 to smoothly sense the position of the first magnet 7, the first magnet 7 may be disposed on the first pulley 2 and near the edge of the first pulley 2, and similarly, the second magnet 9 may be disposed on the second pulley 3 and near the edge of the second pulley 3, which is not restrictive, of course, a person skilled in the art may flexibly set the specific positions of the first hall sensor 6, the second hall sensor 8, the first magnet 7, and the second magnet 9 in practical applications as long as the position of the first magnet 7 can be sensed by the first hall sensor 6, the position of the second magnet 9 may be sensed by the second hall sensor 8.
Preferably, in order to ensure the consistency of the first pulley 2 and the second pulley 3, the first pulley 2 and the second pulley 3 may be configured to be identical, that is, the first pulley 2 and the second pulley 3 may be manufactured by using the same mold during the manufacturing process, and accordingly, the installation structure for installing the first magnet 7 on the first pulley 2 and the installation structure for installing the second magnet 9 on the second pulley 3 are configured to be identical in position and structure, and the installation position of the first magnet 7 on the first pulley 2 and the installation position of the second magnet 9 on the second pulley 3 are configured to be identical.
Further preferably, the shoe washing machine of the present invention may firstly wash the top surface of the shoes and then wash the bottom surface of the shoes, or may firstly wash the bottom surface of the shoes and then wash the top surface of the shoes, this makes it necessary to turn the mounting rack for mounting the shoe 180 degrees before brushing one of the top and bottom surfaces of the shoe, and specifically, the first pulley 2 and the second pulley 3 rotate 180 degrees around their axes respectively, at this time, the position of the first magnet 7 on the first pulley 2 also rotates 180 degrees relative to the axis of the first pulley 2, the position of the second magnet 9 on the second pulley 3 also rotates 180 degrees relative to the axis of the second pulley 3, so as to avoid the occurrence of dead zone, the circumferential position of the first hall sensor 6 relative to the first pulley 2 may be set 180 degrees different from the circumferential position of the second hall sensor 8 relative to the second pulley 3. In a possible embodiment, when the top surface of the shoe is brushed, the first magnet 7 and the second magnet 9 are both in the upper left position, and when the bottom surface of the shoe is brushed, the first magnet 7 and the second magnet 9 are both in the lower right position, so that the stagnation positions set on the first belt wheel 2 and the second belt wheel 3 can be detected through the combination of the first hall sensor 6 and the second hall sensor 8, and the induction blind area is avoided.
Further, the present invention provides a control method for a pulley device, still taking the above-described structure as an example, the control method including rotating the first pulley 2 and the second pulley 3 in synchronization; detecting the rotational position of the first pulley 2 and the rotational position of the second pulley 3; the positions of the first pulley 2 and the second pulley 3 are selectively corrected based on the detection results of the rotational position of the first pulley 2 and the rotational position of the second pulley 3. That is, during the rotation of the first pulley 2 and the second pulley 3, the positions of the first magnet 7 and the second magnet 9 are detected by the first hall sensor 6 and the second hall sensor 8, respectively, and then the first pulley 2 and the second pulley 3 are corrected in synchronization. Specifically, the step of "selectively correcting the positions of the first pulley 2 and the second pulley 3 based on the detection results of the rotational position of the first pulley 2 and the rotational position of the second pulley 3" specifically includes: selectively correcting the positions of the first pulley 2 and the second pulley 3 according to the rotational position of the first pulley 2 if only the rotational position of the first pulley 2 is detected; selectively correcting the positions of the first pulley 2 and the second pulley 3 according to the rotational position of the second pulley 3 if only the rotational position of the second pulley 3 is detected; if the rotational position of the first pulley 2 and the rotational position of the second pulley 3 are detected at the same time, the positions of the first pulley 2 and the second pulley 3 are selectively corrected according to the rotational position of any one of the first pulley 2 and the second pulley 3. In other words, when the position of the first magnet 7 can be detected by the first hall sensor 6, the position correction of the first pulley 2 and the second pulley 3 is performed by the position of the first magnet 7 detected by the first hall sensor 6, when the position of the second magnet 9 can be detected by the second hall sensor 8, the position correction of the first pulley 2 and the second pulley 3 is performed by the position of the second magnet 9 detected by the second hall sensor 8, when the first hall sensor 6 can detect the first magnet 7 and the second hall sensor 8 can detect the second magnet 9, the position correction of the first pulley 2 and the second pulley 3 can be performed by either one of the first hall sensor 6 and the second hall sensor 8, and in practical use, the priority ranking can be performed according to the detection positions of the first hall sensor 6 and the second hall sensor 8, that is, if the distance between the first hall sensor 6 and the first magnet 7 is smaller than the distance between the second hall sensor 8 and the second magnet 9, the first hall sensor 6 is preferentially used to correct the positions of the first pulley 2 and the second pulley 3, so as to improve the detection accuracy, and similarly, if the distance between the first hall sensor 6 and the first magnet 7 is larger than the distance between the second hall sensor 8 and the second magnet 9, the second hall sensor 8 is preferentially used to correct the positions of the first pulley 2 and the second pulley 3.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
