Description

Double-section screw mechanism of mixing roll

Technical Field

The utility model relates to a mixing roll technical field specifically is a mixing roll two-section screw rod mechanism.

Background

The rubber mixing equipment is used for mixing the powder and the compounding agents. Meanwhile, the rubber can be plasticated, and the rubber can be fed by metal injection, ceramic injection and the like. The mixing mill is divided into an open type rubber mixing mill (an open mill for short) and an internal type rubber mixing mill (an internal mixer for short). The internal mixer is provided with an internal mixing and material manufacturing integrated machine, after materials are mixed according to requirements, the materials are put into a rubber mixer to disperse and mix the powder and the materials to form a uniform mixture, and the uniform mixture is extruded and manufactured to form granules. It is widely used in powder metallurgy, plastics and other industries.

The existing banburying material making adopts a whole screw rod mechanism, in a banburying and granulating integrated machine, a feeding screw rod is under a whole screw mark, and after materials are put into the banburying and granulating integrated machine, a part of powder enters into a gun barrel through a thread groove under the action of pressure and gravity. The existing structure conveys the material entering the thread groove of the gun barrel back to the banburying cavity through the reverse rotation of the screw rod, and the reverse rotation can also prevent the material from flowing into the screw rod. The existing internal mixer is poor in sealing effect, a part of materials enter a thread groove at the position of a gun barrel, the mixing uniformity of the materials is reduced, the materials are poor in mixing uniformity and deviate from a design formula, and meanwhile, the problem that the powder is easily blocked by the materials when the screw rod of the gun barrel needs to be cleaned in time, so that the production difficulty and production time are increased.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a mixing roll two-section screw rod mechanism possesses the advantage of guaranteeing the leakproofness and improving mixed effect, has solved the problem mentioned in the above-mentioned background art.

The utility model provides a following technical scheme: the clamping device comprises a first screw and a second screw, wherein a clamping block is fixedly connected to the end face of the first screw, a clamping groove is formed in the end face of the second screw, and the clamping block is movably clamped on the inner surface of the clamping groove.

Preferably, the first screw and the second screw are arranged on the central shaft together.

Preferably, the first screw and the second screw are connected with the clamping block through clamping grooves, and the clamping grooves allow the clamping block to rotate in the grooves.

Preferably, the screw feeding grooves on the surfaces of the first screw and the second screw are switched between a blocking state and a conducting state during rotation.

This double-section screw rod mechanism of mixing roll through dividing into two sections with the screw rod, during forward rotation, two thread grooves of two screw rods just in time lock each other, and the screw rod twists right ninety degrees during the reversal for the thread groove just opens, in a narrow and small space, along with the rotation of screw rod, accomplishes the function of the break-make of thread groove automatically

Because the joint of the screws at the two ends extends into the hole of the gun barrel by a plurality of millimeters, when the screws rotate forwards, the thread groove is blocked, and materials cannot enter the thread groove in the gun barrel through the thread groove. When the banburying is finished and the extrusion and the material manufacturing are needed, the screw rod is reversely rotated, the thread groove is conducted at the moment, and the material enters the gun barrel through the thread groove. The functions required in the internal mixing of the materials are realized.

Compared with the prior art, the utility model discloses possess following beneficial effect:

1. this two sections screw rod mechanisms of mixing roll, through dividing into two sections with the screw rod, during the forward and reverse rotation, two screw rods just in time lock mutually, and the screw rod twists reverse ninety degrees during the reversal for the thread groove just opens, in a narrow and small space, along with the rotation of screw rod, accomplishes sealed function automatically, avoids addding sealing member, does not need complicated machinery, solves simultaneously sealedly, driven problem, excellent in use effect.

2. This two sections screw rod mechanisms of mixing roll, through dividing into two sections with the screw rod, during the forward and reverse rotation, two screw rods just in time lock mutually, and the screw rod twists reverse ninety degrees during the reversal for the thread groove just opens, in a narrow and small space, along with the rotation of screw rod, accomplishes sealed function automatically, avoids the material to drive away in advance, avoids will spreading inside the material falls back the casing, improves the mixing effect.
