Embodiment 1

[0023] refer to figure 1 and figure 2 , a biodegradable film extruder, comprising an incubator 1, a heating box 13 is fixed in the incubating box 1, a rotating shaft 4 is inserted and rotated in the heating box 13, and a spiral blade is fixed at one end of the rotating shaft 4 located in the heating box 13 16. The other end of the rotating shaft 4 is fixed with a transmission gear 3, and the transmission gear 3 is connected with a driving mechanism. A plurality of equidistant heating plates 15 are fixed in the interlayer of the heating box 13, and the heating plate 15 between the heating box 13 and the incubator 1 The gap is filled with a heat exchange solution, and the heating box 13 can be fixed in the incubator 1 to achieve a heat preservation effect. The filled heat exchange solution can reduce the heat transfer rate and improve the heat preservation effect of the device. The top outer wall of the incubator 1 is fixed and plugged There is an exhaust pipe 14, a pressure r...

Embodiment 2

[0027] refer to image 3 , a biodegradable film extruder, the difference between this embodiment and embodiment 1 is that a slide rail 9 and a fixed block 12 are fixed on the outer wall of the top of the incubator 1, and a screw 10 is threadedly inserted on the fixed block 12, and the two ends of the screw 10 A slider 8 and a rotating handle 11 are respectively fixed, the slider 8 is plugged into the slide rail 9 to form a sliding fit, and one side of the slider 8 is fixedly connected with the discharge plate 6 .

[0028] The working principle of this embodiment: the screw 10 can move laterally when the rotating handle 11 is turned, and the screw 10 drives the slider 8 and the discharge plate 6 to move laterally, and then the distance between the discharge plate 6 and the inner wall of the feed pipe 5 can be adjusted. , and carry out the limiting function of the unloading plate 6, the slide rail 9 can play the role of limiting and guiding when the slider 8 moves laterally, so ...

Abstract

The invention discloses a biodegradable film extruder, which comprises a heat preservation box. The heat preservation box is internally and fixedly provided with a heating box, a rotating shaft is rotationally inserted in the heating box, the rotating shaft is located at the end of the heating box, and fixed to spiral blades, the other end of the rotating shaft is fixed to a transmission gear, thetransmission gear is connected with a driving mechanism in a transmission mode, a heating box interlayer is internally and fixedly provided with a plurality of heating plates distributed in an equal-interval mode, a gap between the heating box and the heat preservation box is filled with a heat exchange solution, an exhaust pipe is fixedly inserted in the outer wall at the top of the heat preservation box, the exhaust pipe is fixed to a pressure relief valve, an extrusion mechanism is fixedly inserted in one side of the heating box, one side of outer wall of the top of the heat preservation box is fixed to a feed hopper, the top end of the feed hopper is fixed to a feeding pipe, and the bottom end of the feed pipe penetrates through the heat preservation box and is inserted in the heatingbox. According to the biodegradable film extruder, the heat transfer rate can be reduced, the heat preservation effect of the device is improved, and energy are saved.

Description

technical field [0001] The invention relates to the technical field of degradable film extruders, in particular to a biodegradable film extruder. Background technique [0002] Biodegradable film is a new type of plastic film produced to meet the needs of society for environmental protection. The main raw material is a mixture of degradable masterbatch and plastic particle masterbatch. Degradation is achieved by the erosion of plastic film by microorganisms in nature or by the oxidation of sunlight. [0003] After retrieval, the Chinese patent publication number is CN205148874U, which discloses a biodegradable film extruder, including an operation panel and an extruder housing, and the extruder housing is fixedly installed above the base of the extruder. The operation panel is installed on the left end of the rotation rod of the operation panel, a motor is arranged on the left side of the extruder casing, and a processing tank is arranged inside the extruder casing, and a sp...
