Utility model provides a conduction band machine printing in-process, warp because of the final drive roller atress, the step-by-step inaccurate problem that leads to can offset the deformation that produces because of the cylinder effort through setting up the running roller that pushes down.
Description
Technical Field
The utility model belongs to the technical field of belt guide machine drive disk assembly, especially, it is relevant with a shape adjustment mechanism is prevented deforming by belt guide machine driving roller.
Background
The driving roller can be deformed to influence the printing precision when the belt guide machine is tensioned, and the circumferences of the two sides and the middle of the belt guide machine are not equal, so that the belt guide is easy to arch.
SUMMERY OF THE UTILITY MODEL
To the problem that above-mentioned background art exists, the utility model aims at providing a shape adjustment mechanism is prevented deforming by conduction band machine driving roller.
Therefore, the utility model adopts the following technical scheme: the anti-deformation adjusting mechanism for the belt guide machine driving roller comprises a main driving roller and is characterized by further comprising a support, a lower pressing roller lifting mechanism, a pressing roller wheel and a pressing roller wheel supporting frame, wherein two ends of the lower pressing roller are supported and installed in a vertical long slotted hole formed in the support;
the lower compression roller lifting mechanism comprises a roller and an air cylinder driving mechanism, the air cylinder driving mechanism is fixedly arranged at the bottom of the bracket, the roller is movably arranged on a piston rod of the air cylinder driving mechanism, and the roller is in matched transmission with the lower compression roller;
the pressure roller movable mounting in the pressure roller support frame on, the pressure roller wheel be located the main drive roller top, and with the axis of main drive roller stagger mutually, the pressure roller wheel with the lower compression roller be located respectively the both sides of main drive roller, the main drive roller receives the slant power down of pressure roller wheel and the power of going up to one side of lower compression roller, the main drive roller receives an inward power simultaneously, three power offsets each other, makes its resultant force minimum, the roller deflection is also minimum.
As the supplement and improvement to the technical proposal, the utility model also comprises the following technical characteristics.
The main driving rollers are two in number, the lower pressing roller and the lower pressing roller lifting mechanism are respectively provided with two pairs of main driving rollers corresponding to the two pairs of main driving rollers, and the pressing roller wheels are respectively arranged on two sides of the pressing roller wheel supporting frame and respectively correspond to the main driving rollers.
The utility model discloses following beneficial effect can be reached: the utility model provides an in-process is printed to conduction band machine, warp because of the final drive roller atress, the step-by-step inaccurate problem that leads to can offset the deformation that produces because of the cylinder effort through setting up the running roller that pushes down. The main driving roller can keep the surface straightness in the operation process, so the material is not easy to arch. The utility model discloses simple to operate, the effect is obvious, and the picture splices more easily, and whole breadth does not have deformation, and it is better to print the effect, and the placement is more even.
