The present disclosure relates to the technical field of cotton processing equipment, and one embodiment of the present disclosure provides a deodorizing device for cotton processing, which comprises a treatment tank and a plurality of groups of heating pipes, the heating pipes are all installed in the treatment tank, inner racks are all arranged in the treatment tank, extrusion assemblies are arranged on the treatment tank and the inner racks, and inlet and outlet conveying assemblies are arranged in the treatment tank, the inlet and outlet conveying assemblies comprise a pair of feeding baffles, the feeding baffles are all arranged in the treatment tank, a pair of guide plates are arranged in the treatment tank, two groups of conveying rollers are rotatably connected in the treatment tank, the number of each group of conveying rollers is two, and the conveying rollers are respectively located in the feeding baffles and the guide plates. Through the above technical scheme, the technical problem that when the cotton reaches a high temperature state, the original odor substances will undergo complex physical and chemical changes, the odor is difficult to remove, and a pungent odor is generated in the prior art is solved.

This application discloses a thermoplastic drill bit, relating to the field of drill bit technology, comprising: a shank, a guide extrusion section, and a drill tip extrusion section; one end of the guide extrusion section is connected to the shank, and the diameter of the guide extrusion section is D; the drill tip extrusion section is conical, including a first working section and a second working section, the first working section being connected to the small end of the second working section, and the large end of the second working section being connected to the other end of the guide extrusion section; the first working section is hemispherical, and the surface of the second working section includes spaced-apart first arc-shaped extrusion sections and planar clearance sections; the cross-sectional profile of the second working section is formed by spaced-apart arc-shaped segments formed by the first arc-shaped extrusion sections and straight segments formed by the planar clearance sections, and a first height difference exists between the first arc-shaped segments and the straight segments. This application can improve the machining performance of the drill bit and enhance the surface finish of the machined hole wall.

The present application relates to a kind of rubber processing device, in particular to a kind of efficient rubber mixing method.The present application relates to a kind of rubber processing device, in particular to a kind of efficient rubber mixing method.It includes controller, machine body, motor arranged at both ends of machine body and rubber mixing device arranged in machine body;The rubber mixing device is a screw rod, including transmission shaft and spiral blade, the spiral blade is symmetrically arranged with the center cross section of machine body;The screw rod and the inner surface of machine body are matched with each other;The spiral blade below the feeding port is provided with opening, and the larger end of the opening is towards the rotation direction of spiral blade when working;The beneficial effects of the present application are as follows: by using spiral blade, the screw rod with the center cross section of machine body is symmetrically arranged, the rubber can be extruded to the center of machine body, so that extrusion is replaced by plasticizing;By using controller, the rubber mixing machine can be automatically operated, and production efficiency is improved.
