Description

Technical Field

[0001] The utility model relates to the technical field of bulk molding compound production, in particular to a rapid extrusion device for BMC bulk molding compound. Background Technique

[0002] Bulk molding compound is a thermosetting plastic, which is mixed with various inert fillers, fiber reinforcing materials, catalysts, stabilizers and pigments to form a sticky "putty-like" composite material for compression molding or injection molding;

[0003] Generally, during the production process of bulk molding compound, an extrusion device is required to stir and extrude the raw materials into a formed shape. Usually, after the bulk molding compound is extruded, a cutting mechanism is required to cut it. After the bulk molding compound is cut, it needs to be weighed and packaged manually. The route of the general cutting mechanism and the time interval of each cutting action are the same. When the extrusion amount of the extrusion device is small or the extrusion is uneven, it will cause the cutting weight of the bulk molding compound to be uneven and there may be blockages inside the device at this time. If the method of manual weighing at the back end is used, it is difficult to timely understand the actual weight of the bulk molding compound and it is impossible to timely detect blockages inside the device.

[0004] Therefore, we propose a rapid extrusion device for BMC bulk molding compound. Content of the Utility Model

An auxiliary weighing component is arranged on the fixed frame 7. The auxiliary weighing component can weigh the cut bulk molding compound, eliminating the need for manual weighing later and improving efficiency. By setting an auxiliary cutting component, after the bulk molding compound is extruded by the extrusion device 1, the auxiliary cutting component can cut the bulk molding compound. At the same time, it can support the bulk molding compound during the discharging process to prevent it from being segmented before being cut. At the same time, an auxiliary weighing component is set. The auxiliary weighing component can automatically weigh the segmented bulk molding compound, eliminating the need for manual weighing later and improving the operation efficiency.

[0025] Furthermore, the auxiliary cutting component includes a cutting knife 8. The cutting knife 8 is movably installed on the external connection frame 6. The cutting knife 8 is driven by an electric cylinder, and the electric cylinder is electrically connected to an external controller.

The second driving gear 11 is driven by a servo motor, and the servo motor is electrically connected to an external controller. A first driving gear 10 is rotatably installed on the external connection frame 6. The first driving gear 10 meshes with the second driving gear 11. The first driving gear 10 is fixedly connected to the supporting roller 9. When the second driving gear 11 rotates one full circle, the first driving gear 10 rotates half a circle. By setting an auxiliary cutting component, after the bulk molding compound is extruded by the extrusion device 1, it passes through the inside of the external connection frame 6. By controlling the intermittent downward movement of the cutting knife 8, the bulk molding compound can be cut. When the bulk molding compound passes through the inside of the external connection frame 6, control the second driving gear 11 to rotate and mesh with the first driving gear 10 to drive the supporting roller 9 to rotate. While rotating, the supporting roller 9 can contact the strip-shaped bulk molding compound and support it.

A pull rope 20 is arranged inside the installation box 12. The pull rope 20 is wound around the winding roller 18. One end of the pull rope 20 is fixedly connected to the connecting seat 13. Two fixed pulleys 19 are rotatably mounted inside the installation box 12. The pull rope 20 is movably connected to the two fixed pulleys 19; by providing the auxiliary weighing assembly, the cut bulk molding compound is pushed onto the loading plate 14 by the pusher plate 5. The winding roller 18 is controlled to rotate to relax the pull rope 20. At this time, the loading plate 14 slides downward and contacts the pressure sensor 16. The pressure data reflected by the pressure sensor 16 can reflect the weight of the cut bulk molding compound to achieve the weighing operation. After weighing, the winding roller 18 is controlled to rotate back to wind the pull rope 20 to drive the connecting seat 13 to move back to its original position. Synchronously, the driving gear III 17 is controlled to rotate and mesh with the driving gear III 17 on the other side to drive the loading plate 14 to rotate to a downward inclined state. At this time, the weighed bulk molding compound can slide down to the conveyor belt II 3 and be conveyed to the packaging area for packaging. The strip-shaped bulk molding compound does not need to be weighed manually, and during the processing, the extrusion amount of the plastic can be reflected according to the feedback of the cut weighing data. When the weight data of the bulk molding compound is too low, it means that the extrusion amount of the plastic is too low. At this time, the equipment needs to be adjusted.

[0027] Working principle of the utility model: After the massed mold material is extruded by the extrusion device 1, it passes through the inside of the external frame 6. By controlling the intermittent downward movement of the cutting knife 8, the massed mold plastic can be cut. While the massed mold plastic passes through the inside of the external frame 6, control the driving gear two 11 to rotate and mesh with the driving gear one 10 to drive the supporting roller 9 to rotate. While the supporting roller 9 is rotating, it can contact the strip-shaped massed mold plastic and support it. While the strip-shaped plastic is conveyed forward by the conveyor belt one 2, the supporting roller 9 can support and roll it to assist the output of the massed mold plastic. The cut massed mold plastic is pushed onto the loading plate 14 by the pushing plate 5. Control the winding roller 18 to rotate to relax the pulling rope 20. At this time, the loading plate 14 slides downward and contacts the pressure sensor 16. The pressure data reflected by the pressure sensor 16 can reflect the weight of the cut massed mold plastic to achieve the weighing operation. After weighing, control the winding roller 18 to rotate back to wind the pulling rope 20 to drive the connecting seat 13 to move back to its original position. Synchronously, control the driving gear three 17 to rotate and mesh with the driving gear three 17 on the other side to drive the loading plate 14 to rotate to a downward inclined state. At this time, the weighed massed mold plastic can slide down to the conveyor belt two 3 and be conveyed to the packaging area for packaging. The strip-shaped massed mold plastic does not need to be manually weighed, and during the processing, the extrusion amount of the plastic can be reflected according to the feedback of the cut weighing data.
