Detailed Description

As shown in the figure, the polymer film perforating machine comprises a rack 105, wherein a backing plate 106 is installed on the rack 105 through bolt connection, and the backing plate 106 is made of a plastic plate. A first flattening roller 103 and a second flattening roller 104 are fittingly arranged on one side of the rack 105, and the distance between the outer roller surfaces of the first flattening roller 103 and the second flattening roller 104 is set according to the thickness of a film to be processed. A tension roller 102 and an unreeling machine 101 are sequentially arranged on one side of the first flattening roller 103. A third flattening roller 110 and a fourth flattening roller 111 are fittingly mounted on the other side of the stand 105, and similarly, the distance between the outer roll surfaces of the third flattening roller 110 and the fourth flattening roller 111 is set according to the thickness of the film to be processed. And a winding machine 112 is arranged on one side of the third flattening roller 110. The first flattening roller 103 and the second flattening roller 104 can play a role in conveying the film, and meanwhile, folds on the film can be flattened, so that the reduction of punching precision caused by the presence of the folds is avoided. In order to improve the punching precision, the upper roll surfaces of the first flattening roll 103 and the third flattening roll 110 and the upper end surface of the backing plate 106 are in the same horizontal plane, namely, the film is in a flat state during punching, so that the punching precision of the film is ensured. The third flattening roller 110 and the fourth flattening roller 111 can play a role in conveying the film and can also flatten burrs generated by the punched film.

A support mechanism is mounted on the upper end of the backing plate 106, a transmission mechanism is mounted on the support mechanism, and the transmission mechanism is connected with a mounting plate 116. Specifically, the support mechanism includes support columns 113 mounted at four corners of the upper end of the pad plate 106 by bolts, and support plates 118 are mounted on the support columns 113 by bolts. The transmission mechanism comprises a hydraulic cylinder 123 mounted on the support plate 118, the hydraulic cylinder 123 is connected with a piston rod 122, and the piston rod 122 extends to the lower end of the support plate 118 through a through hole formed in the support plate 118. The lower end of the piston rod 122 is connected with one end of the transmission rod 121, and the other end of the transmission rod 121 is connected with the upper end of the mounting plate 116. The hydraulic cylinder 123 can drive the piston rod 122 to drive the transmission rod 121 to move linearly in the up-and-down direction together with the mounting plate 116. In order to ensure the stability of the mounting plate 116 during movement, guide posts 120 are symmetrically mounted on the upper end of the mounting plate 116, and the upper portions of the guide posts 120 pass through guide sleeves 119 mounted on the support plate 118. The guide post 120 is linearly movable up and down within the guide sleeve 119. When the mounting plate 116 moves up and down, the guide sleeve 119 enables the mounting plate 116 to stably perform linear movement in the up-down direction by limiting the guide post 120.

An air duct 124 is arranged in the mounting plate 116, a first air duct 117 is connected to the air duct 124, and a fan is connected to the first air duct 117. The lower end of the mounting plate 116 is provided with the punching needles 115, and the number of the punching needles 115 is set according to the processing requirement. The perforating needle 115 is provided with a central through hole which is in through connection with the air duct 124. The pad plate 106 under the perforating needle 115 is provided with a through hole 125 corresponding to the perforating needle 115, and the inner wall of the through hole 125 is provided with bristles 126. The perforating needle 115 perforates the film on the backing plate 106 while the mounting plate 116 is linearly moved downward. The lower portion of the perforating needle 115 is inserted into the through hole 125, and the bristles 126 can clean the outer surface of the perforating needle 115. The fan blows air to the first vent pipe 117, so that air flow enters the central through hole of the perforating needle 115 through the vent passage 124, and the air flow blows out residual film materials in the central through hole of the perforating needle 115.

In order to clean the residue left on the film, an air outlet 109 is arranged on one side above the backing plate 106, and the air outlet 109 is connected with a second vent pipe 114. For convenience of control, the first vent pipe 117 and the second vent pipe 114 are connected with a Y-shaped pipe through a pipeline, and the Y-shaped pipe is connected with the fan through a pipeline. The blower may blow both snorkel one 117 and snorkel two 114 together. The air flow blown out from the air outlet 109 can blow off the residual materials on the film, and can cool the equipment at the same time.

In order to collect the residue blown out from the central through hole of the punching pin 115, a collecting frame 107 is provided below the backing plate 106. In order to collect the residue blown off from the film, a baffle plate 108 is obliquely installed at the upper end of one side of the collecting frame 107, and the upper part of the baffle plate 108 extends to the other side of the backing plate 106 opposite to the air outlet 109. The remainder blown off by the airflow from the outlet 109 falls onto the baffle 108 and then falls into the collection frame 107 under the action of gravity. In order to improve the collecting effect of the blown-off residue on the film, the distance between the left side and the right side of the baffle 108 is larger than the distance between the left side and the right side of the air outlet 109, and the side plates 127 are arranged on the left side and the right side of the baffle 108 and can prevent the residue from flying out from the two sides.
