Abstract

The utility model discloses a kind of novel built-in lubrication Melt Pumps, the technical solution adopted is that, including the pump housing, the inside of the pump housing is equipped with transfer passage, and the middle position of transfer passage set there are two intersect cylindricality mounting groove, and the transfer passage of mounting groove two sides is disposed as bell-mouth structure of air, driving shaft and driven shaft are rotatably connected in mounting groove, gear is mounted on the driving shaft and driven shaft, and two gear engagement connections, the two sides of the pump housing are connected with front apron, the utility model inlet and outlet are designed using horn mouth, material enters from import, so that gear is completely attached to material steady and continuous and enters the pump housing, it is discharged from outlet, keep material short in the inlet and outlet residence time, material stock is few, it measures more accurate, it is few to make material remain in the pump housing, avoid rejection rate, driving shaft is designed as axis, enhance input power Transmission fluctuation is to axle sleeve, sealing, the abrasion of 8 word cavitys, so that Melt Pump service life extends.

Description

A kind of novel built-in lubrication Melt Pump

Technical field

The utility model relates to melt pump technical field, specially a kind of novel built-in lubrication Melt Pump.

Background technique

Melt Pump is mainly used for the conveying, pressurization, metering of high-temp high-viscosity polymer melt, and foreign countries are widely used in moulding The extrusion molding of material, resin, rubber, chemical fibre product, such as: granulation, film, tubing, plate, sheet material, staple fibre, light guide are fine The industries such as dimension, medical plastic catheter, it is increasingly developed with mechanical industry, Melt Pump at home market also gradually by industry people Scholar adopts, applies, but in current Melt Pump most of on the market charging and the setting of discharge port, so that material exists The residence time of pump body is longer, and residual is more, so that the rejection rate of product is higher.

Utility model content

In view of the problems of in the prior art, the utility model discloses it is a kind of it is novel it is built-in lubricate Melt Pump, adopt Technical solution is, including the pump housing, and the inside of the pump housing is equipped with transfer passage, and the middle position of transfer passage is equipped with The cylindricality mounting groove of two intersections, and the transfer passage of mounting groove two sides is disposed as bell-mouth structure of air, rotation connects in mounting groove It is connected to driving shaft and driven shaft, gear, and two gear engagement connections, the pump are mounted on the driving shaft and driven shaft The two sides of body are connected with front apron, and the front apron is externally connected to cold water plate, the both ends of the driven shaft and driving shaft One end pass through bearing block and be fixed on front apron, the other end of the driving shaft runs through and extends to the outside of cold water plate.

Cold water plate top outside the cold water plate is connected with connector.

Axle sleeve is equipped at the position of the inside corresponding gear two sides of the pump housing.

The utility model has the beneficial effects that the utility model inlet and outlet are designed using horn mouth, material enters from import, makes Gear completely attaches to material steady and continuous and enters the pump housing, is discharged from outlet, keeps material short in the inlet and outlet residence time, and material stock is few, Metering is more accurate, so that it is few to remain material in the pump housing, avoids rejection rate, and driving shaft is designed as axis, enhances input power Transmission fluctuation is to axle sleeve, sealing, the abrasion of 8 word cavitys, so that Melt Pump service life extends.

Specific embodiment

Embodiment 1

As shown in Figure 1 and Figure 2, the utility model discloses a kind of novel built-in lubrication Melt Pump, the technical solutions of use It is, including the pump housing 5 that the inside of the pump housing 5 is equipped with transfer passage, and the middle position of transfer passage sets that there are two the cylindricalitys intersected Mounting groove, and the transfer passage of mounting groove two sides is disposed as bell-mouth structure of air 8, and 2 He of driving shaft is rotatably connected in mounting groove Gear 9, and two engagement connections of gear 9 are mounted on driven shaft 7, driving shaft 2 and driven shaft 7, the two sides of the pump housing 5 are connected with Front apron 4, front apron 4 are externally connected to cold water plate 3, and the both ends of driven shaft 7 and one end of driving shaft 2 pass through bearing block It is fixed on front apron 4, the other end of driving shaft 2 runs through and extends to the outside of cold water plate 3.

As a kind of optimal technical scheme of the utility model, 3 top of cold water plate outside cold water plate 3 is connected with connector 1。

As a kind of optimal technical scheme of the utility model, it is equipped at the position of 9 two sides of inside corresponding gear of the pump housing 5 Axle sleeve 6.

Working principle of the utility model is: connector 1 and extraneous motor are attached, then the one of transfer passage Side is connect with extraneous feed end, and the other side and the extraneous pipeline of transfer passage are attached, electrical fault is then made, To drive driving shaft 2 to rotate, due to the setting of driving shaft 2 and 2 gear 9 of driving shaft, so that material can be from the pump housing 5 The side of internal transport channel is passed through at the position of gear 9, is then discharged from the other side of transfer passage, to carry out conveying work Industry.

Unspecified component herein is the prior art.

Although above-mentioned be explained in detail specific embodiment of the utility model, the utility model is not limited to Embodiment is stated, within the knowledge of a person skilled in the art, the utility model aims can also not departed from Under the premise of make a variety of changes, without have the modification of creative work or deformation still the protection scope of the utility model with It is interior.
