Description

Novel color master batch meter

Technical Field

The utility model relates to a dosing unit technical field, in particular to novel look female counter.

Background

In the industries of injection molding, extrusion, blow molding and the like, various plastic raw materials, color master batches, additives and lubricants are needed, and different raw material formulas are needed for producing different products. The color master metering device is specially designed for a color master metering adding application process of injection molding equipment by utilizing a screw volumetric metering principle. It is suitable for various plastic molding industries. The HA color master batch meter is designed by a single metering station, the controller measures the actual stopping and pre-molding time of the injection molding screw and the actual feeding screw rotating speed of each time, and calculates the accurate feeding speed so as to add the color master batch according to the set amount of the color master batch in the next stopping time circulation. When the product is changed, the stopping time is also changed, and the motor speed is automatically adjusted according to the set addition amount by controlling the stopping and pre-molding time according to the new stopping and pre-molding time.

Some color concentrate meters will add a small amount of auxiliary material, which requires a feed mechanism with a feed sleeve and an extrusion screw for metered addition. Because the raw materials and the dust that can not let the previous weighing when look female counter weighs different formulas remain in the pay-off sleeve, so need clear up in the pay-off sleeve and just can reuse. In order to facilitate cleaning, I developed a color master batch meter structure capable of being opened (the patent name is a feeding structure for the color master batch meter easy to clean, and the application number is 201822167474.1), and the extrusion screw rod can be conveniently detached. But the following disadvantages exist in the using process:

① the screw rod will have the tendency to withdraw from the feeding sleeve when being subjected to the axial reaction force of the material, resulting in the locking;

② are oversized axially and occasionally hit by the installation site.

There is a need for an improved structure to solve the above problems.

Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1 to 4, the utility model discloses a novel look female counter, including mount pad 1, be fixed in pay-off sleeve 11 on the mount pad 1, the pin joint is in pay-off sleeve 11 extrude screw rod 2 and be used for driving and extrude screw rod 2 pivoted step motor 3, step motor 3 is on a parallel with the axis of extruding screw rod 2 and installs in the side of mount pad 1, the end of extruding screw rod 2 is fixed with first gear 21, step motor 3 drives one with the second gear 31 of first gear 21 meshing, mount pad 1 is equipped with emergency exit 12 that can open in the one side that is close to first gear 21. In use, the stepper motor 3 drives the second gear 31 to rotate, which in turn rotates the first gear 21 to effect rotation of the extrusion screw 2. The safety door 12 is closed at this time, preventing foreign matter from being caught between the gears. During cleaning, the safety door 12 is opened and the extrusion screw 2 is withdrawn from the feed sleeve 11. The first gear 21 and the second gear 31 are both located on the openable side, and the first gear 21 can be removed along with the extrusion screw 2. Because a gear transmission mode is adopted, the stepping motor 3 does not need to occupy the axial space of the extrusion screw 2, but is arranged on the side of the feeding sleeve 11, and the axial size is reduced.

As shown in fig. 3 and 4, the mounting base 1 is provided with a through hole 14 at an outlet close to the first gear 21, the extrusion screw 2 is sleeved with a screw fixing plate 22 capable of being inserted into the through hole 14, and the extrusion screw 2 can only rotate around the shaft in the screw fixing plate 22. The through hole 14 can prevent the screw fixing plate 22 from rotating as long as the through hole is of a non-circular structure, and the screw fixing plate 22 limits the axial direction of the extrusion screw 2, so that the extrusion screw 2 can be prevented from being disengaged under the reaction force of the material.

As shown in fig. 3 and 4, the through-hole 14 is square, and the screw fixing plate 22 is also square. The structure not only can realize the purpose of preventing the rotation of the screw fixing plate 22, but also is more convenient to process.

As shown in fig. 1 to 4, the side of the screw fixing plate 22 is provided with a notch 221, and the mounting base 1 is provided with a spring pin 4 capable of being inserted into the notch 221. In the working state, the spring pin 4 can block the notch 221, so that the screw rod fixing plate 22 has the function of stopping back; under the clearance state, spring catch 4 pulls out, just so can take off very fast and extrude screw rod 2, compares and has promoted clearance efficiency in screw fixation.

As shown in fig. 2 and 3, the safety door 12 is hinged to a side surface of the mounting base 1. When cleaning, the safety door 12 can be opened to any angle and stopped, and the operation is convenient.

As shown in fig. 1 and 2, the mounting base 1 is provided with a magnet 13 capable of attracting the free end of the safety door 12. The safety door 12 is made of magnetic conductive material, the safety door 12 can be kept in a closed state through the magnetic attraction 13, and the danger caused by the automatic opening of the safety door 12 due to vibration in work is prevented.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
