Description

Quick detachable grinding roller structure of ball grinder for ball pen

Technical Field

The utility model relates to a related technical field of ballpoint especially relates to a ballpoint grinds quick detachable grinding roller structure of machine.

Background

The ball-point pen is a writing tool which uses dry and thick ink and is transferred to paper by means of the steel ball which can be freely rotated on the pen point, and has the advantages of simple structure, convenient carrying, lubricating writing and suitability for duplicating, etc. A ball-point pen is a pen using a minute rotary ball made of brass, steel or tungsten carbide, which releases ink onto paper when writing. In the process of manufacturing steel balls, various processes are needed, wherein one step of the process is to grind steel rods into smaller steel balls, and a grinding roller is often needed. Because the steel balls are hard, the grinding roller is easily damaged in the grinding process, and the ground steel balls are not in accordance with requirements, so that the grinding roller needs to be frequently replaced with a new one. The existing grinding roller is troublesome to replace, and the production efficiency is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model relates to an overcome steel ball grinding in-process grinding roller and change inconvenient not enough, provide a quick replacement grinding roller, improve production efficiency's ball-point pen ball grinds quick detachable grinding roller structure of machine.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a quick detachable grinding roller structure of ballpoint ball grinder, includes the pivot, two discoid carousels of pivot fixedly connected with, the carousel is connected with the connector, the connector is cylindric, the side of two carousels passes through the screw connection with connector both ends medial surface respectively, the connector surface is connected with the annular roller area of circle, the roller takes the internal surface and passes through the screw connection with the connector lateral surface.

The center of the rotary disc is fixed with the rotating shaft. The two ends of the connecting body are connected with the rotary table through screws, and the roller belt is connected with the connecting body through screws. When the roller belt needs to be replaced, the connecting body and the rotary table connecting screw are unscrewed, the whole grinding roller is firstly disassembled, the roller belt and the connecting body connecting screw are unscrewed, and then the roller belt and the connecting body are separated. The disassembly is convenient, and the efficiency of replacing the grinding roller is improved.

Preferably, the outer surface of the roll belt is a circular arc surface. The grinding roller is convenient to grind larger irregular steel balls into smaller steel balls in the working process until the steel balls meet the requirements.

Preferably, the roller belt comprises at least three roller belt units connected end to end. The roll belt units are connected end to form a ring, so that only one part of the worn roll belt is convenient to replace, the time is saved, and the materials are saved.

Preferably, the two corresponding ends of the roller belt unit are step-shaped, and the steps at the end parts of the two corresponding ends are matched. The roller belt unit is connected and attached, so that grinding dust is prevented from invading into the grinding roller to damage the grinding roller.

Preferably, the outer side surface of the connecting body is provided with a convex check ring, and the check ring is tightly attached to the end surface of the roller belt. Prevent that the roll area from taking place the skew in the course of the work, it is high to grind efficiency.

Preferably, the end face of the connecting body is flush with the end face of the turntable. The steel balls to be ground are prevented from staying at the side of the grinding roller and not being ground.

The utility model has the advantages that: between roller area and the connector, all with the screw connection between connector and the carousel, easy dismounting, easy operation saves time, improves work efficiency height, reduction in production cost.

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a graph A of FIG. 1;

fig. 3 is a sectional view B-B of fig. 1.

In the figure: 1. the rotating shaft, 2, the rotating disc, 3, the connecting body, 31, the retainer ring; 4, roller belt, 41, roller belt unit.

Detailed Description

The invention is further described with reference to the accompanying drawings and the detailed description.

Example 1:

as shown in fig. 1 and 2, an easily detachable grinding roller structure of a ball grinder for a ball pen comprises a rotating shaft 1, wherein a pair of rotating discs 2 are fixedly connected to the rotating shaft 1 in the axial direction, and the rotating discs 2 are disc-shaped. The rotary disc 2 is connected with a connector 3, and the connector 3 is cylindrical. The side surfaces of the two turntables 2 are respectively connected with the inner side surfaces of the two ends of the connecting body 3 through screws. The end surface of the connecting body 3 is flush with the end surface of the rotating disc 2. The outer surface of the connector 3 is connected with an annular roller belt 4. The outer surface of the roller belt 4 is a circular arc surface. The inner surface of the roller belt 4 is tightly attached to the outer side surface of the connecting body 3 and is connected with the outer side surface of the connecting body through a screw. The outer side of the connector 3 is provided with a convex retainer 31. The retainer rings 31 are arranged around the outer side surface of the connecting body 3 for a circle, two retainer rings 31 are arranged, and the two retainer rings 31 are tightly attached to the two end surfaces of the roller belt 4.
