SUMMERY OF THE UTILITY MODEL

The utility model provides a roller structure application scope to existence among the prior art is narrow, easily influences production efficiency, problem that the input cost is high, the utility model provides an adjustable roller structure, its application scope is wide, adjusts convenient operation swift, need not to carry out the dismantlement change operation of gyro wheel and pivot, can satisfy the requirement that not unidimensional product was placed, can improve production efficiency, reduces the input cost.

The adjustable roller structure comprises a rotating shaft and two rollers symmetrically sleeved on two sides of the rotating shaft, and is characterized by further comprising two adjusting devices respectively corresponding to the rollers, wherein the adjusting devices are used for adjusting the positions of the rollers on the rotating shaft.

It is further characterized in that:

the adjusting device comprises hoops and fixing rings which are distributed on two sides of the idler wheel and fixed with the rotating shaft, and springs which are arranged between the idler wheel and the hoops and are sleeved with the rotating shaft, and the fixing rings are sleeved on the rotating shaft and are adjustable in position;

a metal washer is arranged between the spring and the roller, and the metal washer is sleeved on the rotating shaft;

the two rotating shaft fixing devices are fixed at two ends of the rotating shaft and are symmetrically distributed;

the rotating shaft fixing devices comprise transmission check rings, flanges and bearing assemblies, and the transmission check rings and the bearing assemblies are fixed on two sides of the flanges;

the rotating shaft is connected with the driving device through a chain wheel, and the chain wheel is fixed at one side end of the rotating shaft.

Adopt the above structure of the utility model, following beneficial effect can be reached: adjusting device symmetric distribution corresponds with the gyro wheel in pivot both sides, consequently can be according to the product size, through adjusting device adjusting roller in the position of pivot, and it need not to carry out the dismantlement change operation of gyro wheel with the pivot, can satisfy the requirement that different size specification products were placed, adjusts convenient operation swiftly, has improved production efficiency, has reduced the input cost.

Detailed Description

Referring to fig. 1 and 2, an adjustable roller structure comprises a rotating shaft 1, two rollers 2 symmetrically sleeved on two sides of the rotating shaft 1, and two adjusting devices respectively corresponding to the rollers 2, wherein the adjusting devices are used for adjusting the positions of the rollers 2 on the rotating shaft 1, each adjusting device comprises an anchor ear 3 and a fixing ring 4, the anchor ears are distributed on two sides of the rollers 2 and fixed with the rotating shaft 1, the springs 5 are arranged between the rollers 2 and the anchor ears 3 and sleeved with the rotating shaft 1, and the fixing rings 4 are sleeved on the rotating shaft 1 and are adjustable in position; a metal washer 6 is arranged between the spring 5 and the roller 2, and the metal washer 6 is sleeved on the rotating shaft 1; the spring is connected with the roller through a metal washer; the fixing ring 4 can also adopt the existing hoop, so that the fixing ring is convenient to disassemble and assemble, and further convenient to adjust the position;

the roller structure also comprises two rotating shaft fixing devices, wherein the two rotating shaft fixing devices are used for connecting the rotating shaft 1 with a guide rail (not shown in the figure, and the conventional guide rail structure can be adopted); the rotating shaft fixing devices comprise transmission retainer rings 7, flanges 8 and bearing assemblies 9, and the transmission retainer rings 1 and the bearing assemblies 9 are fixed on two sides of the flanges 8 and are fixed with the rotating shaft; the transmission retainer ring 7, the flange 8 and the bearing assembly 9 ensure that the rotating shaft and the guide rail can be stably connected; the rotating shaft 1 is connected with a driving device (which can adopt the existing conventional stepping motor) through a chain wheel 10, the chain wheel 10 is fixed at one side end of the rotating shaft 1, and the driving device drives the chain wheel 10 to rotate so as to drive the rotating shaft to rotate along with the rotating shaft.

The utility model is applied to the transmission system of the cleaning machine, is used for conveying the washing basket, and the washing basket is placed on the two rollers 2, the rollers 2 are cylindrical structures, the outer side ends of which are provided with annular convex edges, the annular convex edges protrude out of the outer surface of the cylindrical rollers 2 and are vertical to the outer surface of the cylindrical rollers 2, and the washing basket is blocked between the two rollers 2, thereby effectively preventing the washing basket from sliding off due to vibration; when the basket size changes, for example when the basket size increases, with the gyro wheel reverse regulation, increase the distance between two gyro wheels 2, specific: and in the same way, when the size of the washing basket is reduced, the fixed ring 5 oppositely adjusts the roller 2, so that the distance between the two rollers 2 is reduced, and the requirement for placing the small-size washing basket is met.

What has been described above is only a preferred embodiment of the present application, and the present invention is not limited to the above embodiments. It is to be understood that other modifications and variations directly derivable or suggested by those skilled in the art without departing from the spirit and scope of the present invention are to be considered as included within the scope of the present invention.
