Description

Technical Field

[0001] The utility model relates to the technical field of preparation of radium carving materials, in particular to stirring equipment for polymer radium carving materials. Background Art

[0002] Laser engraving materials usually refer to materials used in laser engraving processes. During the preparation process, polymer laser engraving materials need to be fully and evenly stirred by stirring equipment to ensure the consistency and stability of their performance. However, the existing stirring equipment for laser engraving materials has a poor effect on raw material mixing and cannot guarantee the quality of laser engraving material production.

[0003] In order to address the above problems, the existing Chinese patent with announcement number CN219618232U proposes an environmentally friendly flame-retardant laser engraving material preparation device. While the device stirs the raw materials through a stirrer, the protrusions on the edge of its matching stirring paddle continuously collide with the protrusions on the inner wall of the stirring tank, causing the stirring tank to vibrate, thereby causing the raw materials inside to shake, so that the raw material mixing effect is better, ensuring the quality of the produced laser engraving materials.

[0004] However, although the above-mentioned environmentally friendly flame-retardant radium carving material preparation equipment can stir the raw materials through the stirrer and use the protrusions to collide with the bumps, thereby causing the raw materials in the stirring tank to shake, so that the raw material mixing effect is better, the environmentally friendly flame-retardant radium carving material preparation equipment uses the protrusions to collide with the bumps, so that the shaking amplitude of the raw materials in the stirring tank is limited, thereby resulting in a low raw material mixing efficiency. Therefore, the utility model provides a stirring device for polymer radium carving materials to meet the needs. Utility Model Content

[0031] like Figures 1 to 5As shown, an embodiment of the utility model provides a stirring device for polymer laser engraving materials, including a stirring drum 1, a stirring shaft 8 and a motor 7 for driving the stirring shaft 8 to rotate, a plurality of stirring rods 13 are equidistantly arranged along the length direction of the stirring shaft 8, the end of the stirring rod 13 away from the stirring shaft 8 is movably connected with a resistance block 14, the stirring rod 13 is provided with a movable groove 18 for the resistance block 14 to move, the inner wall of the stirring drum 1 is provided with a resistance plate 10 for intermittent resistance with the resistance block 14, and a connecting mechanism 9 is provided in each of the plurality of stirring rods 13, when the resistance block 14 is in resistance with the resistance plate 10, the connecting mechanism 9 connects adjacent stirring rods 13, and when connecting adjacent stirring rods 13, the connecting mechanism 9 forms a plurality of notches for raw materials to pass through.

[0032] Specifically, when the motor 7 drives the stirring shaft 8 and the stirring rod 13 to rotate, the stirring rod 13 drives the resistance block 14 to resist the resistance plate 10, so that the resistance block 14 is squeezed to slide into the movable groove 18, so that the resistance block drives the connecting mechanism 9 to connect adjacent stirring rods 13 and define a groove for the raw material to pass through, thereby increasing the contact area between the stirring rod 13 and the raw material, and improving the stirring efficiency of the raw material. Compared with directly connecting adjacent stirring rods 13, the advantage of this embodiment is that it can intermittently control the connection between adjacent stirring rods 13 to avoid the situation where the raw material is damaged by long-term and large-area contact with the stirring rod 13, and solves the problem that the existing laser engraving material stirring equipment uses the protrusion to collide with the protrusion so that the shaking amplitude of the raw material in the stirring tank is limited, thereby making the mixing efficiency of the raw material low.

[0033] like Figure 5As shown, in the present embodiment, the connecting mechanism 9 comprises a push rod 91, one end of which is fixedly connected to the abutment block 14, and the other end is movably connected to the stirring rod 13, a cavity 93 for the push rod 91 to move is provided in the stirring rod 13, a plurality of movable rods 95 are relatively movably arranged on the upper and lower sides of the stirring rod 13, and are equidistantly arranged along the length direction of the stirring rod 13, a movable groove 94 for the movable rod 95 to move is provided in the stirring rod 13, the movable groove 94 is connected to the cavity 93, and a plurality of movable rods 95 are hinged with connecting rods 92, and one end of the connecting rod 92 away from the movable rod 95 is hinged to the push rod 91, a spring 15 is sleeved on the push rod 91, the spring 15 is located in the movable groove 18 and is fixedly connected to the abutment block 14, a limit plate 17 is sleeved on the push rod 91, and the limit plate 17 is located in the cavity 93, when the movable rod 95 moves out along the movable groove 94, the adjacent stirring rod 1 3 are connected to each other. Specifically, when the resistance block 14 moves toward the movable groove 18, the resistance block 14 squeezes the spring 15 and pushes the push rod 91 to move. The push rod 91 drives the moving rod 95 to slide out along the moving groove 94 through the connecting rod 92, so that the moving rod 95 extends outward from the stirring rod 13, so that the moving rods 95 between adjacent stirring rods 13 are connected to each other, so that a groove for the raw material to pass through is formed between adjacent moving rods 95. When the resistance block 14 is separated from the resistance plate 10, the spring 15 drives the resistance block 14 to reset, and at the same time, the limit plate 17 can prevent the resistance block 14 from being separated from the movable groove 18; further, the end of the moving rod 95 away from the connecting rod 92 is fixedly connected with a blocking block 16, and the diameter of the blocking block 16 is larger than the diameter of the moving groove 94. The blocking block 16 can avoid limiting the moving rod 95.

[0034] like Figure 3 and Figure 4 As shown, in this embodiment, there are two abutment plates 10 which are relatively arranged on the inner wall of the mixing drum 1 . The abutment plates 10 are arc-shaped structures and have inclined end surfaces inclined along the rotation direction of the mixing shaft 8 .

[0035] like Figure 1 and Figure 2 As shown, in the present embodiment, the upper and lower ends of the mixing drum 1 are connected with a feed port 3 and a discharge port 4, the fixed part of the mixing drum 1 is fixedly connected with a support frame 2 for supporting the motor 7, the support frame 2 is provided with a controller 6 for controlling the motor 7, and a plurality of support columns 5 are fixedly connected to the bottom of the mixing drum 1. Specifically, the installation between the feed port 3 and the discharge port 4 and the mixing drum 1 is prior art and can be controlled by an electric valve. At the same time, the present application document is intended to the laser engraving material mixing equipment, and its connection with the subsequent equipment is prior art. For details, reference may be made to the patent document with announcement number CN219618232U.

[0036] Working principle:

[0037] When the motor 7 drives the stirring shaft 8 and the stirring rod 13 to rotate, the stirring rod 13 drives the resistance block 14 to resist the resistance plate 10, so that the resistance block 14 is squeezed to slide into the movable groove 18, and the resistance block 14 squeezes the spring 15 and pushes the push rod 91 to move. The push rod 91 drives the moving rod 95 to slide out along the moving groove 94 through the connecting rod 92, so that the moving rod 95 extends outward from the stirring rod 13, so that the moving rods 95 between adjacent stirring rods 13 are connected to each other, so that a groove for the raw material to pass through is formed between adjacent moving rods 95, thereby increasing the contact area between the stirring rod 13 and the raw material, and improving the stirring efficiency of the raw material. When the resistance block 14 is separated from the resistance plate 10, the spring 15 drives the resistance block 14 to reset, which solves the problem that the existing laser engraving material stirring equipment uses the protrusion to collide with the protrusion so that the shaking amplitude of the raw material in the stirring tank is limited, thereby making the mixing efficiency of the raw material low.
