Abstract
The utility model relates to a synchronous recovering and extruding device of scraps, comprising a screw rod, a machine barrel and a hopper, wherein the screw rod is positioned in the machine barrel; the upper part of the machine barrel is provided with a feeding inlet; the lower part of the hopper is connected with the feeding inlet; and a concave opening is arranged on the inner wall of the machine barrel at one side of the lower part of the feeding inlet. The synchronous recovering and extruding device has the advantages that by arrangement of the concave opening, the gap between the screw rod at the lower part of the feeding inlet and the single edge of an inner cavity of the machine barrel is enlarged, the feeding quantity of the scraps is increased, the phenomenon of material returning or feedback is improved and the uniform feeding of the scraps into a main extruder is ensured.
Description
Technical field
The utility model relates to a kind of screw extruder, and particularly a kind of rim charge reclaims extrusion device synchronously.
Background technology
Be used for plastics at present and extrude the screw extruder of industry, comprise screw rod, hopper, machine barrel, screw rod is positioned at machine barrel; Hopper is positioned at the machine barrel top; Its lower end is communicated with the machine barrel inner chamber, through the rotation of screw rod the gap of the plastic grain in the hopper between screw rod and machine barrel internal chamber wall is sent to, sends in the process; Through at the heating machine barrel, make rim charge fusion through the machine barrel inner chamber.Its weak point is: the plastic grain in the hopper falls in the spin slot of screw rod at the discharging opening of hopper, in the screw rod rotary course, produces the tip clearance feed back of rim charge from screw rod, is not easy charging.
Summary of the invention
The purpose of the utility model is exactly the weak point in the background technology, provides a kind of rim charge to reclaim extrusion device synchronously.
For achieving the above object, the utility model adopts following technical scheme: rim charge reclaims extrusion device synchronously, comprises screw rod, machine barrel and hopper; Screw rod is positioned at machine barrel; Machine barrel has feeding mouth on the top, and the hopper bottom is connected with feeding mouth, and the machine tube inner wall of feeding mouth bottom one side is provided with recess.
For a kind of optimization of the utility model, this screw rod is a left-handed screw, and then recess is positioned on the inwall of machine barrel front side.
For a kind of optimization of the utility model, this screw rod is a right handed screw, and then recess is positioned on the inwall of machine barrel rear side.
The utility model is compared with background technology, has through offering recess, has increased the monolateral gap of the screw rod and the machine barrel inner chamber of feeding mouth bottom, strengthens the rim charge feed quantity, has improved feed back or counter and has expected phenomenon, guarantees that rim charge evenly sends into main extruder.

Fig. 1 is the A-A cutaway view.
Fig. 2 is that rim charge reclaims extrusion device master TV structure sketch map synchronously.
The specific embodiment
Embodiment 1: with reference to Fig. 1 and 2.Rim charge reclaims extrusion device synchronously, comprises screw rod 2, machine barrel 1 and hopper 3, and screw rod 2 is positioned at machine barrel 1, and machine barrel has feeding mouth 1a on 1 top, and hopper 3 bottoms are connected with feeding mouth 1a, and machine barrel 1 inwall of feeding mouth 1a bottom one side is provided with recess 1b.When this screw rod 2 is a left-handed screw, then recess 1b is positioned on the inwall of machine barrel 1 front side.When this screw rod 2 is a right handed screw, then recess 1b is positioned on the inwall of machine barrel 1 rear side.
What need understand is: though present embodiment is to the utility model detailed explanation of contrasting; But these explanations; It is simple declaration to the utility model; Rather than to the restriction of the utility model, any innovation and creation that do not exceed in the utility model connotation all fall in the protection domain of the utility model.
