Technical Field

[0001] The invention relates to the technical field of masterbatch processing, in particular to a raw material mixing device for masterbatch processing. Background Art

[0002] Masterbatch is a plastic processing aid, mainly used in the production process of plastic products. Masterbatch is composed of excess chemical additives, carrier resins and dispersants. It is made by mixing various additives, fillers and a small amount of carrier resin, and then through the process of metering, mixing, melting, extruding, pelletizing and other processing by extruders and other equipment. Color masterbatch is a common masterbatch. During the masterbatch processing, the pigment particles need to be evenly mixed and attached to the resin. However, during the masterbatch production mixing process, the existing mixing device has the problem that the pigment particles are easily deposited at the bottom of the mixing box, which makes it difficult to ensure that the middle and upper layer materials in the mixing box are evenly mixed with the pigment particles, thereby affecting the processing quality. Therefore, in view of the above problems, a raw material mixing device for masterbatch processing is designed to better meet the actual use needs. Summary of the invention

The screw feeding rod is driven to rotate by the motor, and the action of the screw feeding rod and the fixed cylinder is cooperated to lift the material on the lower side of the mixing box upward.

[0005] Preferably, a feed port is installed at the upper end of the mixing box, a discharge valve port is installed at the lower end of the mixing box, and support feet are also installed at equal angles at the lower end of the mixing box.

The fixed rod is symmetrically fixed to the lower side of the dispersion disk, and the stirring rod is evenly fixed on the fixed rod.

[0007] Preferably, the fixed rod is slidably connected to a movable frame, and a push plate is fixed on the movable frame, and the push plate slides in contact with the stirring rod, and at the same time, both sides of the push plate are inclined structures, and the push plate is driven by the movable frame to move left and right, so that the material can be pushed synchronously during the rotating stirring process of the material, thereby further ensuring the mixing effect of the material.

[0008] Preferably, a spherical rod is also fixed on the movable frame, and the spherical rod is nested in the groove on the elliptical ring for sliding, and the elliptical ring is fixed on the fixed cylinder. When the movable frame rotates, the sliding action between the spherical rod and the groove on the elliptical ring can provide a basic force for the reciprocating motion of the movable frame, thereby ensuring the normal operation of the device.

[0013] Preferably, a mounting rod is fixed on the fixing frame, and a detection camera is installed on the lower end surface of the mounting rod. The detection camera can be used to detect the sampled material, and whether the material is completely mixed can be determined by judging the color and brightness of the material, thereby ensuring the production quality of the product.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The raw material mixing device for masterbatch processing adopts a dispersing mechanism with a lifting function, which can lift the materials deposited at the bottom of the mixing box upward and disperse them, thereby ensuring the mixing effect of the materials. Specifically, the materials at the bottom of the mixing box can be lifted upward through the action of the motor, the fixed cylinder and the spiral feeding rod. When the materials are lifted onto the dispersion plate, the materials are dispersed to the surroundings through the rotating centrifugal action of the dispersion plate, so that the materials are evenly mixed, thereby improving the mixing effect of the materials; 2. The raw material mixing device for masterbatch processing adopts a linked mixing mechanism, which can realize multiple stirring and mixing of materials, thereby improving the mixing efficiency of materials. Specifically, the spiral feeding rod rotates to drive the fixed rod, the stirring rod, the movable frame and the push plate to rotate, and the horizontal rotation of the stirring rod can realize the primary mixing and stirring of materials. The sliding action between the spherical rod and the elliptical ring allows the push plate to reciprocate, thereby realizing the horizontal push of materials in the mixing box, and then the materials can be moved horizontally to a certain extent, and then the secondary mixing of materials is realized, ensuring the mixing effect of the materials and improving the mixing efficiency of the materials. 3. The raw material mixing device for masterbatch processing adopts a linked intermittent sampling and detection mechanism, which can sample and detect the mixed materials during the material mixing process, so as to determine whether the materials are completely mixed and detect the mixing quality of the materials. Specifically, when the dispersion disk rotates to disperse the materials, part of the materials can enter the sampling slot through the sampling port, and cooperate with the action of the driving gear, the second gear and the first gear to make the rotating rod, the rotating block and the sampling slot rotate intermittently. When the sampled material rotates to the bottom of the detection camera, the color and brightness of the material are detected by the detection camera to determine whether the materials are completely mixed and the mixing quality of the materials.

[0019] A feeding port 101 is installed at the upper end of the mixing box 1, and a discharge valve port 102 is installed at the lower end of the mixing box 1, and a support foot 103 is also installed at the lower end of the mixing box 1 at an equal angle; the mixing mechanism 4 includes a fixed rod 401, a stirring rod 402, a movable frame 403, a push plate 404, a spherical rod 405 and an elliptical ring 406, the fixed rod 401 is symmetrically fixed to the lower side of the dispersion disk 304, and the stirring rod 402 is evenly fixed on the fixed rod 401; the fixed rod 401 is slidably connected to the movable frame 403, and a push plate 404 is fixed on the movable frame 403, and the push plate 404 contacts and slides with the stirring rod 402, and both sides of the push plate 404 are inclined structures; a spherical rod 405 is also fixed on the movable frame 403, and the spherical rod 405 is nested in the groove on the elliptical ring 406 for sliding, and the elliptical ring 406 is fixed on the fixed cylinder 301; When using the raw material mixing device for masterbatch processing, such as Figure 1-Figure 7As shown, firstly, the materials to be mixed are put into the mixing box 1 through the feed port 101 in proportion. At this time, the discharge valve port 102 is in a closed state. After the materials are put in, the motor 2 is started, and the motor 2 drives the spiral feeding rod 303, the dispersion disk 304 and the baffle plate 305 to rotate clockwise. When the spiral feeding rod 303 rotates, the fixed cylinder 301 cooperates with the lower side of the mixing box 1 to lift the materials upward. When the materials are lifted onto the dispersion disk 304, the materials can be dispersed to the surroundings through the rotating centrifugal effect of the dispersion disk 304, so as to facilitate the mixing of the materials. When the dispersion disk 304 rotates, the fixed rod 401, The stirring rod 402, the movable frame 403 and the push plate 404 rotate. The stirring rod 402 rotates to achieve horizontal stirring of the materials and primary mixing of the materials. When the movable frame 403 rotates, the spherical rod 405 is synchronously driven to rotate. The sliding action between the spherical rod 405 and the groove on the elliptical ring 406 enables the elliptical ring 406 and the movable frame 403 to reciprocate in an orderly manner, thereby driving the push plate 404 to move. The reciprocating motion of the push plate 404 can push the materials at the inner edge and the middle position of the mixing box 1, thereby ensuring the uniformity of material mixing and effectively ensuring the mixing effect of the materials. The detection mechanism 5 includes a fixed frame 501, a cylinder 502, a sampling port 503, a feeding port 504, a rotating rod 505, a first gear 506, a second gear 507, a driving gear 508, a rotating block 509, a sampling slot 510, a mounting rod 511 and a detection camera 512. The fixed frame 501 is fixed in the mixing box 1, and the fixed frame 501 is fixed with the cylinder 502, and the sampling port 503 is opened on the left side of the cylinder 502, and the feeding port 504 is opened on the front side of the lower end of the cylinder 502; the rotating rod 505 is connected to the bearing on the cylinder 502, and the first gear 506 is fixed on the rotating rod 505, and the first gear 5 06 is meshed with the second gear 507 to realize transmission, and the bearing of the second gear 507 is connected to the mixing box 1; the second gear 507 is meshed with the driving gear 508, and the driving gear 508 is fixed on the spiral feeding rod 303, and the driving gear 508 rotates one circle to make the second gear 507 rotate 90°; a rotating block 509 is fixed at the lower end of the rotating rod 505, and the rotating block 509 is slidably connected to the cylinder 502, and four sampling slots 510 are opened at equal angles on the rotating block 509; a mounting rod 511 is fixed on the fixed frame 501, and a detection camera 512 is installed on the lower end surface of the mounting rod 511; During the device impact process, such as Figure 1-Figure 7As shown, when the spiral feeding rod 303 rotates, the driving gear 508 is synchronously driven to rotate. Through the transmission effect between the driving gear 508, the second gear 507 and the first gear 506, the rotating rod 505, the rotating block 509 and the sampling slot 510 are orderly intermittently rotated. When the sampling slot 510 cooperates with the sampling port 503, a part of the material splashed outward by the centrifugal effect of the dispersion disk 304 enters the sampling slot 510 through the sampling port 503, thereby realizing the automatic sampling of the material. After the sampling is completed, the sampled material can be driven to move by the clockwise rotation of the rotating block 509 and the sampling slot 510. When the sampled material rotates 180° clockwise, the sample material is just moved. Move to the bottom of the detection camera 512. Through the function of the detection camera 512, the sample material can be detected. The color and brightness of the material can be judged to determine whether the material is mixed completely (to ensure the accuracy of the detection data, 5-10 tests are required, and the detection interval time is 1min-2min). The mixing quality of the material can also be detected. After the sample material detection is completed, the rotating block 509 and the sampling slot 510 continue to rotate, so that the sample material can continue to move. When the lower end of the sampling slot 510 cooperates with the discharge port 504, the sample material falls through the discharge port 504 into the mixing box 1 to avoid material waste. This is the working principle of the raw material mixing device for masterbatch processing.
