The invention discloses a flame retardant, fireproof and high temperature resistant polyethylene film laying device. The flame retardant, fireproof and high temperature resistant polyethylene film laying device comprises a first supporting frame and further comprises supporting plates placed at the two ends of the first supporting frame and used for supporting a polyethylene film; locating framesare movably arranged at the middle parts of the two supporting plates; uprights are arranged at the middle parts of two third supporting frames; a third roll wheel used for flattening the film is movably arranged between the two uprights; and the end parts of the two third supporting frames are fixedly connected with the two ends of a holding handle. According to the flame retardant, fireproof andhigh temperature resistant polyethylene film laying device, a polyethylene film rolling wheel can be supported by using a locating frame; as the locating frame can rotate, the polyethylene film rolling wheel on the locating frame rotates during pushing the first supporting frame so as to unwind the polyethylene film so as to lay the polyethylene film on the ground; and by enabling the third rollwheel to press the polyethylene film, the polyethylene film can generate a tangential force to the polyethylene film rolling wheel to pull the polyethylene film rolling wheel to rotate so as to realize an automatic unwinding function.

The invention belongs to the technical field of marking equipment for packaging materials, and discloses a packaging bag forming and labeling integrated machine, which includes a workbench, on the workbench, an unwinding part, a hot-pressing part and a conveying part are sequentially arranged on the workbench, and the conveying part It includes two overlapping conveyor belts, the conveyor belts are driven by a motor, the worktable is provided with a placement slot, the bottom conveyor belt is located in the placement slot, and the upper surface of the bottom conveyor belt is coplanar with the upper surface of the worktable; The mounting frame on the table is vertically slidably connected with a plurality of heat-pressed blocks arranged side by side, and the adjacent heat-pressed blocks are fixed by connecting rods; The first cam that drives the push rod to move up and down; icons are set on the working surface of the hot pressing block. The invention solves the problem that an additional process needs to be added for label printing in the prior art, resulting in lower production efficiency of packaging bags.

The invention discloses an evaporation tube unwinding device, which comprises a turntable support frame, a turntable mechanism, a turntable drive mechanism, a spring swing arm mechanism, a swing arm detection mechanism and a swing arm support frame. The turntable mechanism is installed on the turntable support frame, used to place the evaporating tube roll, and can rotate around its center. The turntable drive mechanism is used to drive the turntable mechanism to rotate. The spring swing arm mechanism and the swing arm detection mechanism form a mechanism for detecting whether the current evaporation tube is loose. When the unwinding evaporator tube is slack, turn off the turntable drive mechanism, otherwise turn on the turntable drive mechanism to rotate the evaporator tube coil on the turntable mechanism for unwinding. As a result, the evaporating tube unwound from the present invention is always in a stretched state, thereby facilitating the straightening of the evaporating tube unwound.

The invention relates to the technical field of polaroid preparation, in particular to continuous die cutting and arranging equipment for polaroids and a production technology thereof. The continuousdie cutting and arranging equipment for the polaroids comprises a controller, a machining workbench, an unwinding mechanism, a die cutting mechanism, an unloading mechanism and an arranging mechanism,and the unwinding mechanism, the die cutting mechanism, the unloading mechanism and the arranging mechanism are sequentially arranged on the machining workbench along the linear sequence; the interval distance between the unloading mechanism and the die cutting mechanism is between 2.5 cm and 3.5 cm; the downstream end of the machining workbench is provided with an unloading gap groove; the arranging mechanism comprises a replacing plate installed under the unloading gap groove, a storing assembly arranged beside the replacing plate and a material poking assembly arranged over the replacing plate, and a lifting assembly used for driving the replacing plate to vertically move to the unloading gap groove is arranged under the replacing plate; and a position sensor which is electrically connected with the controller is installed on one side of the interior of the unloading gap groove. According to the continuous die cutting and arranging equipment for the polaroids and the production technology thereof, the cut polaroids can be automatically collected in a unified mode, full-automatic connection of polaroid unwinding and full-automatic die cutting and arranging is achieved, and the production efficiency of the polaroids is greatly improved.
