Detailed Description

The invention will be further described with reference to the following drawings and examples:

the first embodiment is as follows: referring to fig. 1 and 2, the filter screen punching device comprises a frame 1, an upper transmission roller 2, a lower transmission roller 3 and a punching mechanism, wherein the upper transmission roller 2, the lower transmission roller 3 and the punching mechanism are arranged on the frame;

the punching mechanism comprises a rotating shaft 4, a fixing plate 5, a sliding plate 6, a pushing cylinder 7 and a plurality of groups of contact pins 8, the rotating shaft is parallel to the upper transmission roller and the lower transmission roller, two ends of the rotating shaft are rotatably installed on the rack, the middle part of the bottom surface of the fixing plate is fixedly connected with the outer edge surface of the top of the rotating shaft, two groups of sliding rails 9 are arranged on the top surface of the fixing plate, the sliding plate is slidably arranged on the two groups of sliding rails, the pushing cylinder is installed on the left side of the top surface of the fixing plate, the plurality of groups of contact pins are installed on the sliding plate from front to back at intervals, the right sides of the contact pins are arranged outside the right sides of the sliding plate, and the output;

the front end of pivot passes the frame set up in the front side of frame, be equipped with a telescopic cylinder 10 on the preceding lateral wall of frame, telescopic cylinder set up in the left side top of pivot, the front end of pivot is equipped with a connecting plate 11, the right side of connecting plate with the front end of pivot links to each other, telescopic cylinder's output shaft with the left side of connecting plate is rotated and is linked to each other.

In this embodiment, when the in-service use, the filter screen is from the right side to the top outer fringe face and the left side outer fringe face of last drive roller downwards, through the right side outer fringe face of lower drive wheel again, carry towards the left side, the middle part of product 12 is in the right side of contact pin like this, and at this in-process, the product is in the tensioning state, and the output shaft of push cylinder stretches out and contracts, drives the reciprocal right side and the left movement of contact pin, when moving right, the contact pin can be with the product jack, accomplishes the work of punching. Wherein, if say that the contact pin is perpendicular with the product, the size of contact pin equals with the size that punches, if say that the contact pin is from left to right slope downward setting, the contact pin is when punching the product like this, because contact pin and product slope, the size that punches like this can be greater than the diameter of contact pin. The smaller the angle between the pin and the product, the larger the size of the punch. In this embodiment, in order to adjust the size of punching, can adjust telescopic cylinder's stroke, under the telescopic cylinder output shaft retraction state, mounting panel and slide and product slope set up, and the contained angle between contact pin and the product is less than 90 degrees, when telescopic cylinder output shaft stretches out, drives pivot anticlockwise rotation through the connecting plate, makes the contained angle increase between contact pin and the product, and the maximum is 90 contained angles. At this in-process, the in-process that the product punched, can punch at the interval, a set of hole site size is little, and a set of hole site size is big in addition, can adjust according to actual conditions like this, also can make the size that the product punched fixed, only need according to actual conditions, select telescopic cylinder whether work, and application scope is wider. In this embodiment, when need adjusting to the size of punching, only need adjust telescopic cylinder's stroke can, just can adjust the size that the single punched, efficient, of high quality, the cost is cheaper moreover. Consequently when in actual use, the filtration pore size of different product filter screens is different grades, and the material selection all is the same, and in order reduce cost, the simultaneous processing of being convenient for, the size of punching can be adjusted to direct stroke to telescopic cylinder adjusting, and the cost is cheaper, work that moreover can be continuous guarantees efficiency and quality of punching.

The outer edge surface of the left side of the upper transmission roller and the outer edge surface of the right side of the lower transmission roller are arranged on the same plane.

Referring to fig. 1 and 2, a limiting plate 13 is arranged on the rack, a left side surface of the limiting plate and a left outer edge surface of the upper transmission roller are arranged on the same plane, and the limiting plate is arranged on the right side of the rotating shaft.

The limiting plate is provided with a plurality of groups of vertical strip-shaped through grooves 14, and each group of vertical strip-shaped through grooves is just opposite to one group of contact pins.

In the punching process, in order to prevent to elongate the product and lead to punching the off normal or the quality of punching not good, adopt the setting of limiting plate, can support and spacing the position of punching the hole department, guarantee the quality of punching, through the setting that leads to the groove, can let the position to punching the hole, be convenient for normal punching prevents the rupture of contact pin.

Referring to fig. 2, a plurality of sets of mounting holes 15 are formed in the sliding plate, the plurality of sets of mounting holes are uniformly distributed on the sliding plate from front to back, and the left side and the right side of each mounting hole are communicated with the left side and the right side of the sliding plate.
