Abstract

The utility model belongs to the technical field of screw charging devices, and particularly relates to a screw charging device for adding particles finely and precisely, mainly comprising a screw installed in a conveying pipe, wherein the top of the rear end of the conveying pipe is provided with a charge port; the bottom of the front end of the conveying pipe is provided with a discharge port; the screw comprises a threaded end and a flat straight end; the flat straight end is installed on the front end of the conveying pipe through a shaft sleeve; and the threaded end is connected with a coupler through a fixing sheet and a connection plate. The screw charging device has the advantages that the problems of a colorant about uneven distribution and intermittent charge under the state of a screw with a full thread are solved, the charging device is enabled to be available for continuous and stable charge, and the purpose of precise metering is achieved.

Description

Screw

Technical field

The utility model belongs to the screw technical field, specifically is meant a kind of trace, accurately adds the screw of particle.

Background technology

The full thread design is adopted in convention, the screw rod of screw, can effectively add dusty raw materials, then can in carrier pipe, cause the uneven situation of filling for feed particulate material.For example reinforced, metering field at plastics machinery; The look mother is as a kind of novel high polymer material special coloring agent, is evenly to be attached to the pigment of super quantity among the resin and the aggregated particle thing that makes, because the screw rod of screw adopts the full thread design in the prior art; When carrying in screw thread, particle cause charging not smooth because of the space is narrow and small; Usually be trapped in and reach one or several metering cycles in the screw thread, so the raw material filling is inhomogeneous in the carrier pipe, make granular look mother intermittent in the interpolation process; Be difficult to realize look female accurate measurement in the unit interval; Particularly when the metering of trace, short time, in addition can appear in one or the continuous several metering cycle can't metered feeding situation owing to can not feed in raw material sustainedly and stably; Therefore the screw requirement of accurate measurement of arriving, thus cause the plastic products aberration obvious.Look is female to add, measures coarse problem in order to improve, and the spirit that the applicant is adhering to the research innovation, keeping on improving is utilized its professional eye and professional knowledge, works out a kind of trace, accurately adds the screw of particle.

Summary of the invention

The purpose of the utility model is to overcome the deficiency of prior art, and a kind of trace is provided, accurately adds the screw of particle.

The utility model is realized in the following manner; Mainly comprise the screw rod that is installed in the carrier pipe; The top, rear end of carrier pipe is provided with charging aperture, and front bottom end is provided with discharging opening, and said screw rod comprises the end of thread and flat end; Flat end is installed in the front end of carrier pipe through axle sleeve, and the end of thread links to each other with shaft coupling through stator and connecting plate.

The advantage of the utility model is, connects and has separated look mother skewness under the screw rod state of full thread, and the problem that blanking is interrupted guarantees that feeding device can continue, stably feed in raw material, and reaches the purpose of being convenient to accurate measurement.

Description of drawings

Fig. 1 is the utility model structural representation.

The specific embodiment

Preferred embodiment below in conjunction with 1 pair of the utility model of accompanying drawing is described further; In, the metering device reinforced at plastics machinery, mainly comprise the screw rod 5 that is installed in the carrier pipe 6, the top, rear end of carrier pipe 6 is provided with charging aperture 62; Front bottom end is provided with discharging opening 61; Said screw rod 5 comprises the end of thread 51 and flat end 52, and flat end 52 is installed in the front end of carrier pipe 6 through axle sleeve 4, and the end of thread 51 links to each other with shaft coupling 3 through stator 2 and connecting plate 1.

During use, start feeding device, shaft coupling 3 drives screw rod 5 rotations, and simultaneously that the look mother is reinforced from charging aperture 62, under the promotion of the end of thread 51, the look mother is transported to the terminal of the end of thread 51 in carrier pipe 6; The look mother is squeezed in the look mother that flat end 52 is assembled by the female raw material of the look of continuous interpolation more from behind; Promptly when the look mother is transported to flat end 52 via the end of thread 51; The look female of being pushed the front by the end of thread 51 lasting look mothers that carry; Make the female raw material of Dry Sack in the small space of carrier pipe 6 front ends evenly, closely arrange, and at the uniform velocity push ahead, finally from discharging opening 61 blankings.Because granular look mother can not be in the end of thread 51 always; Can not form delay because of the space is narrow and small; Therefore the look mother evenly arranges in the carrier pipe 6 of terminal to the discharging opening 61 of the end of thread 51, thereby connects look mother skewness under the screw rod state of full thread, the problem that blanking is interrupted of having separated; Guarantee that feeding device can continue, stably feed in raw material, and reaches the purpose of being convenient to accurate measurement.

And when the discharge end of the utility model and machine are a tip-tilted mode of low-angle and install, when promptly the flat end 52 of screw rod 5 is a little more than the end of thread 51, thereby can prevent that the look mother from obtaining result of use better because of the accumulation landing.

The above embodiment has only expressed a kind of embodiment of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.

Claims

1. screw; Mainly comprise the screw rod (5) that is installed in the carrier pipe (6); The top, rear end of carrier pipe (6) is provided with charging aperture (62), and front bottom end is provided with discharging opening (61), it is characterized in that: said screw rod (5) comprises the end of thread (51) and flat end (52); Flat end (52) is installed in the front end of carrier pipe (6) through axle sleeve (4), and the end of thread (51) links to each other with shaft coupling (3) through stator (2) and connecting plate (1).
