Description

A jewelry raw material extruder

technical field

The utility model relates to the field of material forming, in particular to an ornament raw material extruder.

Background technique

In the process of making jewelry, it is usually necessary to mix resin powder and environmental protection oil first, and then stir it into resin mud. The prepared resin mud needs to be processed into semi-finished products of various shapes, that is, raw materials for jewelry, such as cylindrical, long strip, Oval, etc., the jewelry raw materials after molding can be directly used in jewelry processing. The traditional processing method of jewelry raw materials is: extrude the resin mud by manpower, and the extrusion head and the barrel are integrated. Each barrel can only correspond to one extrusion shape, and jewelry raw materials with different cross-sectional shapes need to be processed. It is often necessary to replace different barrels. The traditional processing method is time-consuming, laborious, inconvenient to replace the extrusion head, and the scope of application of the barrel is small.

Utility model content

The technical problem to be solved by the utility model is: the problems of low efficiency and inconvenient operation of the extruder in the prior art.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a jewelry raw material extruder, including an extrusion head, a connecting ring, a barrel, a frame, a driving mechanism, and a piston head.

The extrusion head passes through the connecting ring, the connecting ring is connected to the front end of the barrel, and the extrusion head is clamped between the connecting ring and the barrel.

Both the rear end of the barrel and the driving mechanism are installed on the frame, the piston head is arranged on the movable part of the driving mechanism, and the piston head faces the cavity of the barrel.

Optimally, the extruder further includes a connecting ring through which the extrusion head is connected to the barrel.

Optimally, protrusions are provided on the outer ring surface of the connecting ring.

Optimally, the extrusion head and barrel are provided with sealing rings.

Optimally, the sealing ring is a rubber sealing ring.

Optimally, the barrel is provided with a handle.

Optimally, a hopper is provided on the barrel, and the hopper is set on the end of the barrel away from the extrusion head.

Optimally, the frame is provided with a first notch and a second notch, and the two are distributed on opposite sides of the frame.

Optimally, the rear end of the barrel is arranged in the first opening, the driving mechanism is arranged in the second opening, and the rear end of the barrel and the driving mechanism are both mounted on the frame through screws.

Optimally, the driving mechanism is a hydraulic cylinder.

The beneficial effects of the utility model are:

1. The extrusion head and the barrel are made into a separate type, and the connecting ring is used to connect the two together, which is convenient for the replacement of the extrusion head. If it is necessary to extrude jewelry materials with different cross-sectional shapes, it only needs to be replaced with an extrusion of the corresponding shape. It is convenient, practical and efficient to work in the early stage;

2. Use the hydraulic drive mechanism to replace the traditional manual operation, saving time and labor in the production process;

3. The traditional production method needs to remove the barrel, and then feed the material to extrude. After adding a hopper to the barrel in this plan, you only need to feed directly into the hopper when feeding, and you don’t need to remove the barrel to feed, which is easy to operate. At the same time, it saves production time and improves production efficiency;

4. The principle and structure of this extruder are relatively simple, and the manufacturing cost is relatively low.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail.

In the description of the present utility model, it should be noted that the terms "first" and "second" are only used for description purposes, and should not be understood as indicating or implying relative importance.

Embodiment one:

As shown in FIG. 1 , a jewelry raw material extruder includes an extrusion head 1 , a connecting ring 2 , a barrel 3 , a frame 4 , a driving mechanism 5 , and a piston head 6 .

As shown in Figure 1-2, the extrusion head 1 is provided with through holes, which can be set in different shapes according to actual production requirements, so as to extrude jewelry materials with different cross-sectional shapes.

The extrusion head 1 passes through the connecting ring 2 , and the connecting ring 2 is connected to the front end of the barrel 3 by screwing, and the extrusion head 1 is clamped between the connecting ring 2 and the barrel 3 .

As shown in FIG. 3 , a protrusion 21 is provided on the outer ring surface of the connecting ring 2 , and a rubber sealing ring (not shown in the figure) is provided between the extrusion head 1 and the barrel 3 .

As shown in Figure 1-2, the rear end of the barrel 3 and the driving mechanism 5 are all mounted on the frame 4 by screws, and the piston head 6 is arranged on the movable part of the driving mechanism 5. The driving mechanism 5 in this embodiment is Hydraulic cylinder, the piston head 6 is fixed on the piston rod of the hydraulic cylinder by screws, and the piston head 6 is facing the cavity of the barrel 3. When the piston rod of the hydraulic cylinder moves, the piston head 6 can be in the cavity of the barrel 3 back and forth motion. A handle 31 is provided on the barrel 3 for easy removal of the barrel 3 .

As shown in FIG. 3 , the frame 4 is provided with a first notch 41 and a second notch 42 , which are distributed on opposite sides of the frame 4 .

As shown in Figure 1-2, the rear end of the barrel 3 is set in the first gap 41, and the driving mechanism 5 is set in the second gap 42, and the rear end of the barrel 3 and the driving mechanism 5 are both installed on the frame by screws. 4, the installation process is as follows: 1. Put the rear end of the barrel 3 into the first gap 41, and then fix the rear end of the barrel 3 to the frame 4 on both sides of the first gap 41 with screws 2. Put the drive mechanism 5 into the second gap 42, and then fix the drive mechanism 5 to the frame 4 on both sides of the second gap 42 with screws.

Both the barrel 3 and the drive mechanism 5 are put into the gap from the openings of the two notches. This setting solves the inconvenience of installing the barrel 3 and the drive mechanism 5 on the rack when the distance between the barrel 3 and the drive mechanism 5 is relatively close. 4 on the question.

Embodiment two:

As shown in FIG. 4 , the difference between this embodiment and the first embodiment is that: the barrel 3 is provided with a hopper 7 , and the hopper 7 is arranged at the end of the barrel 3 away from the extrusion head 1 .
