The invention discloses a kind of Biodegradable mulch perforating press, in the time will punching to Biodegradable mulch, first the mulch film reel of blow molding is set on the feed roller of perforating press, by one of the Biodegradable mulch bottom of walking around first time take-up roll of charging, walk around again the top of take-up roll in charging first, according in charging first, the quantity of lower take-up roll is walked around respectively in each charging first, lower take-up roll, be delivered to again between front upper pinch roll and front lower pinch roll, front upper pinch roll can carry out the gap between up-down adjustment and front lower pinch roll according to the thickness degree of mulch film, front lower pinch roll drives active rotation by power, front lower pinch roll and front upper pinch roll clamping engagement, drive the passive rotation of front upper pinch roll, mulch film is through front upper, between lower pinch roll, front upper, lower pinch roll clamping engagement is carried backward, in the time that mulch film is delivered to charging the second take-up roll group position, mulch film is first walked around the bottom of second time take-up roll of charging, walk around again the top of take-up roll in charging second, according in charging second, the quantity of lower take-up roll is walked around respectively in each charging second, lower take-up roll, upwards be delivered to again charging guide roller, charging guide roller leads to mulch film, make it reach the lower bolster apparent height of punch mechanism, then be delivered to and install, the mould bases position of lower bolster, drive down punch die to move up by lower cylinder, lower punch die upwards promotes mulch film and contacts with the upper trimming die under cope match-plate pattern, upper trimming die carries out punching to mulch film, mulch film after punching is delivered to discharging guide roller again, by discharging guide roller, it is led, be delivered to again rear adjustable type pinch roll position, by rear upper pinch roll and rear lower pinch roll to mulch film clamping engagement, lower pinch roll active rotation after power drives, rear lower pinch roll and rear upper pinch roll clamping engagement, thereby the upper driven rotation of pinch roll after driving, on rear, lower pinch roll drives mulch film to be delivered to output take-up roll group position, mulch film is first walked around the bottom of the lower take-up roll of output, walk around again the top of the upper take-up roll of output, according in output, the quantity of lower take-up roll is walked around respectively in each output, lower take-up roll, last mulch film is transported to coiled strip roller, mulch film after driving coiled strip roller to punching by power is reeled.This programme adopts Biodegradable mulch to walk around successively charging the first take-up roll group, front adjustable type pinch roll, charging the second take-up roll group, charging guide roller, punch mechanism, discharging guide roller, rear adjustable type pinch roll, after output take-up roll group on coiled strip roller, by charging the first take-up roll group, charging the second take-up roll group and output take-up roll group are strained mulch film, make mulch film in the time of punching, be able to tensioning, avoid mulch film in the time of punching to produce fine wrinkle, the quantity that wherein goes up take-up roll is identical with the quantity of lower take-up roll, for example go up, when lower take-up roll is 8, upper take-up roll is 4, lower take-up roll is 4, on, the more tension effects of lower take-up roll quantity are better, and two or two are connected through oscillating deck with the lower take-up roll of the drop-down tight roller of upper feeding and output, oscillating deck one end is fixed on support, the other end is connected with support by oscillating cylinder, like this in the time of punching, oscillating cylinder promotes of oscillating deck downwards, make under charging on take-up roll and charging the spacing between take-up roll large, under charging, take-up roll is strained mulch film, and in the time carrying mulch film, oscillating cylinder upwards pulls of oscillating deck, make under charging on take-up roll and charging the spacing between take-up roll little, under charging, take-up roll unclamps mulch film, mulch film moves smooth and easy in the time carrying, forward and backward adjustable type pinch roll is carried mulch film, charging guide roller and discharging guide roller lead to the operation of mulch film, punch mechanism carries out punching press to mulch film, the cope match-plate pattern of punch mechanism fixes through check lock lever and top mold frame, lower bolster is slidably matched through two wood side-guides of two side slideways and lower mold holder, can be by manually unclamp check lock lever and regulated afterwards the position, left and right of cope match-plate pattern with hand, and the position, left and right that coordinates to regulate lower bolster of slideway and slide rail, cope match-plate pattern needs corresponding with lower bolster, can arbitrarily regulate like this spacing between same round, and install left in lower mold holder one side, right contiguous block, left, between right contiguous block, establish dwang, dwang is provided with adjusting gear and regulating rotary Moving plate, frame is established adjusting gear rack on both sides, adjusting gear rack is meshed with adjusting gear, drive dwang rotation by rotation regulating rotary Moving plate, adjusting gear on dwang coordinates drive lower mold holder to move forward and backward with adjusting gear rack, lower mold holder drives top mold frame to move forward and backward through connecting rod, thereby regulate the spacing between two groups of punch mechanisms, reach and regulate the spacing between two rounds of going out, by regulating the spacing in each hole of every row, and the spacing of each round, go for so dissimilar crops, for example some crops land occupation area is large, spacing between each hole just needs larger, and some crops land occupation area is little, spacing between each hole is just smaller, the each parts operation of complete machine is harmonious, full-automation, and perforate quality assurance, easy to operate, increase work efficiency.

Biodegradable mulch perforating press of the present invention, the connecting line L of described upper and lower take-up roll and the angle theta of center line I are 15 °.θ angle is large, can accelerate the speed that pulls of degradative plastic film; θ angle is little, can make to pull tightr.Described front upper pinch roll and the nip rolls gap of front lower pinch roll are 0.01mm, and the nip rolls gap of rear upper pinch roll and rear lower pinch roll is 0.01mm.Described upper trimming die die orifice comprises the sharp otch of annular or the sawtooth otch of annular.The sharp otch of annular can directly be worn the Kong Chong of mulch film, the sawtooth otch of annular is gone out indentation after to mulch film punching, and the circular mulch film in hole is still connected with mulch film, and people only need disclose with hand one, just can be disclosed and be worn, the upper trimming die of dissimilar punch die die orifice can be set as required.The described cylinder of installing on mould bases, the piston rod of upper cylinder contacts with mulch film through upper trimming die.In the time the Kong Chong of mulch film will being worn, after punching, drive piston rod to promote the disk film after mulch film punching downwards by upper cylinder, to avoid after punching, this disk film still has part to be connected on mulch film.The connecting rod of described upper and lower mould bases both sides is provided with large buffer spring outward.There is large buffer spring, in the time of punching, upper and lower mould bases has been played to cushioning effect, reduced vibration, reduced noise, guaranteed its service life.Described cope match-plate pattern is upper and lower two, between upper and lower two blocks of cope match-plate patterns, is connected and fixed bar, is provided with minibuffer spring outward at fixed bar.In the time of punching, lower bolster is punching press upwards, and minibuffer spring plays cushioning effect to cope match-plate pattern, guarantees its service life.Under described connecting rod, be equipped with guide pad, have gathering sill on guide pad, guide plate is installed in frame both sides, be shaped with guide rail on guide plate, guide rail matches with gathering sill.There is guide rail to coordinate with gathering sill, when punch mechanism is slided, play the guiding role, guaranteed the precision regulating.
