Strip micro-perforating machine for cement bag

Abstract

The invention discloses a strip micro-perforating machine for a cement bag. The strip micro-perforating machine comprises an electronic control system, a front tension control deviation rectifying mechanism, a perforating mechanism and a rear tension control mechanism, wherein the front tension control deviation rectifying mechanism supplies a strip with appropriate tension after deviation rectifying to the perforating mechanism, the perforating mechanism comprises a wallboard, a front perforating assembly, a reverse perforating assembly, a traction assembly and an adjusting assembly, the front perforating assembly is provided with a first supporting roller and a first needle roller in pair which conduct perforating on the front face of the strip, the reverse perforating assembly is connected to a discharging end of the front perforating assembly and provided with a second supporting roller and a second needle roller in pair which conduct perforating on the reverse face of the strip, the traction assembly is connected to a discharging end of the reverse perforating assembly and used for pulling the strip to go forward continuously at a constant speed to achieve continuous perforating operation of the strip, the adjusting assembly conducts fine adjustment on space between the first supporting roller and the first needle roller and space between the second supporting roller and the second needle roller, and the rear tension control mechanism is connected to a discharging end of the traction assembly to conduct tension control on the strip.

Description

technical field [0001] The invention relates to the technical field of cement bag processing and manufacturing, in particular to a strip material punching machine for cement bags. Background technique [0002] Cement bag is a special bag used to pack cement. Now the compound film plastic woven cement bag is widely used in the market. At present, cement production enterprises usually use gas and mechanical conveying cement filling method when filling cement. If cement filling The exhaust problem during filling is not solved well. On the one hand, it will affect the filling efficiency, and on the other hand, it will also cause the bag weight pass rate to fail to meet the requirements. When solving the exhaust problem, it is necessary to consider running, popping, and ash leakage during filling. Phenomenon and moisture-proof problems during transportation and use. Contents of the invention [0003] The object of the present invention is to provide a strip micro-hole punching...
