Description

Technical Field

[0001] This utility model relates to the field of plastic masterbatch technology, specifically to an extrusion disc that facilitates adjustment of the diameter of plastic masterbatch particles. Background Technology

[0002] Plastic masterbatch is a special material used for coloring plastic products. It is mainly composed of pigments or dyes, carriers, and additives. Its full name is color masterbatch, also known as color seed. It is a new type of special colorant for polymer materials, also known as pigment preparation. Plastic masterbatch is mainly used for coloring plastic products and can provide various colors and properties. In the extrusion production process of plastic masterbatch, the raw material of plastic masterbatch is extruded through an extrusion disc. In the existing technology, the diameter of plastic masterbatch is adjusted by adjusting the orifice of the die in the extrusion disc according to different production needs. During the adjustment process, the die in the extrusion disc needs to be replaced. The die is removed by disassembling the connection between the die and the extrusion disc, and then the replaced die is installed in the extrusion disc and fixed by the connection. However, some extrusion discs have multiple connection points between the die and the extrusion disc to increase the fixation of the die. During the adjustment process, the connection needs to be disassembled and reassembled multiple times, which makes the adjustment of the diameter of plastic masterbatch time-consuming and affects the production efficiency of plastic masterbatch.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This embodiment provides a technical solution: an extrusion disc for easy adjustment of the diameter of plastic masterbatch, including an extrusion disc body 1, providing space for the setting of extrusion molding components, an extrusion mold 2 at the front end of the extrusion disc body 1, through the extrusion hole in the middle of the extrusion mold 2, plastic masterbatch raw material is extruded and shaped, the diameter of plastic masterbatch is adjusted by changing the diameter of the extrusion hole, the outer arc surface of the extrusion disc body 1 is provided with sliding grooves 4, the interior of each sliding groove 4 is slidably connected with a top plate 5, a push ring 6 is provided between the outer edges of the three top plates 5, a sealing gasket 7 is provided on the outer edge of the rear side of the extrusion mold 2, pushing the push ring 6 causes the top plate 5 to slide in the sliding groove 4, and the top plate 5 applies a forward force to the extrusion mold 2, and also includes an installation mechanism 3;

[0021] Mounting mechanism 3 includes insert plates 31, a rotating ring 32, and grooves 33. The insert plates 31 are slidably connected to the grooves on the outer edge of the extrusion disc 1. The annularly distributed insert plates 31 are fitted with slots on the surface of the extrusion die 2. The rotating ring 32 is rotatably connected to the rotating grooves on the outer edge of the extrusion disc 1. The inner arc surface of the rotating ring 32 is provided with grooves 33 that fit with the insert plates 31. When the rotating ring 32 is rotated, the insert plates 31 can move up and down when they are inside the grooves 33, facilitating extrusion. When the extrusion mold 2 is disassembled, and the insert plate 31 contacts the inner arc surface of the rotating ring 32, it simultaneously prevents the three insert plates 31 from leaving the slots on the surface of the extrusion mold 2, allowing for quick installation of the extrusion mold 2. The installation mechanism 3 also includes a limiting plate 34 and a screw 35. The limiting plates 34 are respectively set on the outer arc surface of the rotating ring 32. The limiting plates 34 are located in the clearance grooves on the outer arc surface of the extrusion disc 1. The screw 35 is slidably connected in the connecting grooves on the surface of the limiting plates 34. The lower end of the screw 35 is connected to the left side of the extrusion disc 1. The screw hole at the end is threaded. During disassembly, rotating the screw 35 causes it to move upward through the threaded connection between the screw 35 and the screw hole at the left end of the extrusion disc 1, providing clearance for the clockwise rotation of the limiting plate 34. During installation, rotating the screw 35 in the opposite direction causes it to move downward, and the limiting plate at the upper end of the screw 35 drives the limiting plate 34 to rotate counterclockwise. The installation mechanism 3 also includes springs 37, which are respectively disposed between the insert plate 31 and the inner arc wall of the extrusion disc 1 to restrict the position of the insert plate 31. The installation mechanism 3 also includes guide posts 36, which are respectively disposed on the inner arc wall of the extrusion disc 1. The guide posts 36 pass through the interior of adjacent springs 37 and slide through the guide holes on the surface of the insert plate 31, providing guidance and support for the extension and retraction of the springs 37 and the movement of the insert plate 31. The front and rear sides of the insert plate 31 are inclined at the end near the extrusion mold 2. By applying a horizontal force to the insert plate 31, the insert plate 31 is moved away from the slot on the surface of the extrusion mold 2.

[0022] The working principle of the extrusion disc for easy adjustment of plastic masterbatch diameter provided by this utility model is as follows: During the production of plastic masterbatch, the raw material enters through the feed hole at the rear end of the extrusion disc 1 and is finally extruded from the extrusion die 2. During the extrusion process, the material is cut into granules by an external cutter. When it is necessary to adjust the diameter of the plastic masterbatch, the screw 35 is rotated. The screw 35 is threadedly connected to the screw hole at the left end of the extrusion disc 1, which drives the screw 35 to move upward, providing clearance for the clockwise rotation of the limiting plate 34. Then, the limiting plate 34 pushes the rotating ring 32 to rotate clockwise. When the insert plate 31 enters the groove 33, under the elastic force of the spring 37, the insert plate 31 moves away from the extrusion die 2. The flat end of the insert plate 31 leaves the slot on the surface of the extrusion die 2. At this time, the push ring 6 can be pushed, and the top plate 5 applies a forward force to the extrusion die 2, pushing the extrusion die 2 out of the extrusion disc 1. During the movement of the extrusion die 2, the extrusion die 2 applies a force to the inclined surface of the insert plate 31, overcoming the elastic force of the spring 37, causing the insert plate 31 to leave the slot on the surface of the extrusion die 2, thus completing the disassembly of the extrusion die 2. Similarly, simply insert the new extrusion die 2 into the die groove of the extrusion disc 1, rotate the extrusion die 2, and under the elastic force of the spring 37, insert the insert plate 31 into the slot on the surface of the extrusion die 2, limiting the angle of the extrusion die 2. Then, rotate the screw 35 in the opposite direction, and the screw 35 moves downward. Using the limiting plate at the upper end of the screw 35, the limiting plate 34 is driven to rotate counterclockwise, so that the inner arc surface of the rotating ring 32 contacts the insert plate 31, and at the same time pushes the three insert plates 31 to move towards the extrusion die 2. The insert plates 31 contact the inner wall of the slot of the extrusion die 2, preventing the insert plates 31 from leaving the slot on the surface of the extrusion die 2, limiting the forward and backward movement of the extrusion die 2, and quickly installing the extrusion die 2, which facilitates the adjustment of the diameter of the plastic masterbatch.

[0023] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
