Abstract
The utility model relates to a belt conveying device of a board cross-shearing machine. The belt conveying device of the board cross-shearing machine comprises a driving roller driven by a motor and is characterized in that an end portion supporting roller used for supporting a conveying belt to operate is connected with a shearing base of a cross-shearing device. The end portion supporting roller is connected with a machine frame in a sliding connection mode. The belt conveying device further comprises a looper roll supported by an air cylinder. The belt conveying device of the board cross-shearing machine has the advantages that the end portion supporting roller of a downstream conveying device is connected with the base of the shearing device so that the end portion supporting roller of the downstream conveying device can move forwards and backwards and the change of the length of the conveying belt can be compensated by a movable supporting roller supported by the air cylinder when the end portion supporting roller moves forwards and backwards, so that the distance between the belt conveying device and the cross-shearing device is kept constant and kept small constantly. Therefore, the end portion of a board of the upstream is prevented from being inserted into the bottom of the belt conveying device and the stability of operation of the belt conveying device is improved.
Description
Technical field
This patent belongs to the manufacture field of sheet metal strip, particularly relates to a kind of belt conveyor of sheet material cross cut shears.
Background technology
At present, be cut in the process of sheet material by horizontal mode of cutting at sheet metal strip, adopt the mode of flying shear to carry out more.Be that Scissoring device is in the process of shearing, be along with band carries out moving back and forth on the straight line, be that Scissoring device is driven along with band advances by cylinder or screw rod in the shear history, and in the process of advancing, carry out the shearing operation of vertical direction again by cylinder or motor-driven, after finishing, shear history carries out reverse motion again, like this, the downstream conveying device that sheet material is horizontal cuts device just need and horizontal cutting vacate one section space between the device, to guarantee horizontal operation of cutting device.But when ought carry the sheet material end of upstream again, because this section space is bigger, the sheet material of upstream is entirely a cantilever beam, the problem that its end may occur drooping downwards.The end of upstream sheet material will be inserted into the bottom of belt guide roller quickly like this, causes the damage of sheet material, needs to shut down to handle; if the end can also be used; also need again the end to be retracted into the flattening device place, smooth again, seriously influenced production efficiency.
Summary of the invention
This patent is for solving the technical problem that exists in the known technology and provide a kind of belt conveyor of sheet material cross cut shears, can the remaining and horizontal less spacing of cutting device of belt conveyor.
A kind of belt conveyor of sheet material cross cut shears, comprise by motor-driven driven roller, it is characterized in that: the end portion supports roller that is used for the support belt operation is connected with the horizontal shearing pedestal of cutting device, the end portion supports roller links to each other with frame in the mode that is slidingly connected, and belt conveyor also comprises the loop back roll by cylinder supports.
This patent can also be by the following technical solutions:
The direction of described cylinder supports is parallel to or direction vertical and that the end portion supports roller slides.
Advantage and good effect that this patent has are:
Because this patent adopts technique scheme, the end portion supports roller of downstream conveying device is connected with the shear pedestal, make the end portion supports roller of downstream conveying device to move forward and backward, and the variation of the conveyer belt length when compensating the end portion supports roller and move forward and backward by the movable supporting roller by cylinder supports.Make belt conveyor and horizontal distance of cutting device keep constant and remain less distance, thereby the thing of having avoided the sheet material end of upstream to be inserted into the belt conveyor bottom take place, and has improved the stability of machine operation.
Description of drawings
Fig. 1 is the structural representation of this patent.
Among the figure: 1, driven roller; 2, end portion supports roller; 3, shear pedestal; 4, cylinder; 5, loop back roll.
The specific embodiment
For further understanding utility model content, characteristics and the effect of this patent, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1,
A kind of belt conveyor of sheet material cross cut shears, by motor-driven driven roller 1, the end portion supports roller 2 that is used for the support belt operation is connected with the horizontal shearing pedestal 3 of cutting device, the end portion supports roller links to each other with frame in the mode that is slidingly connected, the direction of sliding is horizontal direction, belt conveyor also comprises the loop back roll 5 that is supported by cylinder 4, and loop back roll also is connected with frame by the mode that is slidingly connected, and the direction of cylinder supports is parallel with the direction that loop back roll slides.
Except the activity direction of loop back roll with the activity direction of end portion supports roller is consistent, can also can also provide bigger movable sleeve amount like this perpendicular to the activity direction of end portion supports roller.
In addition, can also be installed in loop back roll on the fork, and be positioned at the end of fork, make the articulated position of cylinder be positioned at the middle part of fork, make kink obtain bigger movable sleeve amount.
The operating principle of this patent is:
Because the end portion supports roller of downstream conveying device is connected with the shear pedestal, make the end portion supports roller of downstream conveying device to move forward and backward, and the variation of the conveyer belt length when compensating the end portion supports roller and move forward and backward by the movable supporting roller by cylinder supports.When the end portion supports roller along with the horizontal device of cutting together the phase right motion time, the needed strap length in top increases, then loop back roll also moves right thereupon, makes the strap length of bottom shorten, vice versa.These means can so that shear when shearing, make belt conveyor and horizontal distance of cutting device keep constant and remain less distance, can be sent to the belt upper surface of downstream conveying device all the time by the end of the band of upstream, thereby the sheet material end of having avoided the upstream is inserted into the thing of belt conveyor bottom to take place, and has improved the stability of machine operation.
Although by reference to the accompanying drawings the preferred embodiment of this patent is described above; but this patent is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under the enlightenment of this patent; not breaking away under the scope situation that this patent aim and claim protect, can also make a lot of forms, these all belong within the protection domain of this patent.
Claims (2)
1. the belt conveyor of a sheet material cross cut shears, comprise by motor-driven driven roller, it is characterized in that: the end portion supports roller that is used for the support belt operation is connected with the horizontal shearing pedestal of cutting device, the end portion supports roller links to each other with frame in the mode that is slidingly connected, and belt conveyor also comprises the loop back roll by cylinder supports.
2. the belt conveyor of sheet material cross cut shears according to claim 1 is characterized in that: the direction of described cylinder supports is parallel to or the direction vertical and slip of end portion supports roller.
