Description

Technical Field

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

[0002] ‌A masterbatch is a plastic processing aid mainly used in the production process of plastic products. The masterbatch is composed of an excessive amount of chemical additives, carrier resin, dispersant, etc. It is prepared by mixing and kneading various additives, fillers with a small amount of carrier resin, and through processing processes such as metering, mixing, melting, extrusion, and pelletizing by equipment such as an extruder. Among them, a color masterbatch is a common type of masterbatch;

[0003] In the process of color masterbatch processing, it is necessary to uniformly mix and attach pigment particles to the resin. However, in the existing mixing device during the production and mixing of color masterbatch, since the pigment particles are easily deposited at the bottom of the mixing tank, it is difficult to ensure the uniform mixing of the upper and middle layer materials in the mixing tank 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 requirements. Summary of the Invention

[0004] The purpose of the present invention is to provide a raw material mixing device for masterbatch processing to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A raw material mixing device for masterbatch processing, including a mixing tank and a motor. The motor is fixed on the upper end face of the mixing tank. A dispersion mechanism is installed in the mixing tank, and the dispersion mechanism is connected to a mixing mechanism. A detection mechanism is also installed in the mixing tank. The dispersion mechanism includes a fixed cylinder, a support rod, a spiral feeding rod, a dispersion disc, a baffle plate, a connecting rod, and a limiting ring. The fixed cylinder is arranged in the mixing tank, and the fixed cylinder is fixed to the mixing tank through the support rod. A spiral feeding rod is arranged in the fixed cylinder. The spiral feeding rod is connected to the mixing tank by a bearing, and the spiral feeding rod is fixedly connected to the output end of the motor. The dispersion disc is fixed on the spiral feeding rod. A baffle plate fixed on the spiral feeding rod is arranged above the dispersion disc. The baffle plate and the dispersion disc are fixedly connected to each other through the connecting rod. A limiting ring is also fixed on the lower end face of the dispersion disc, and the limiting ring is slidably connected to the fixed cylinder. By driving the spiral feeding rod to rotate by the motor, and with the cooperation of the spiral feeding rod and the fixed cylinder, the lower side materials in the mixing tank are lifted upward. When the materials are lifted to the dispersion disc, through the rotational centrifugal action of the dispersion disc, the materials are dispersed around, so as to uniformly mix the materials.

[0006] Preferably, a feed inlet is installed at the upper end of the mixing box, and a discharge valve opening is installed at the lower end of the mixing box. Moreover, support feet are evenly installed at equal angles at the lower end of the mixing box. Through the functions of the feed inlet and the discharge valve opening, the normal entry and exit of materials can be facilitated, ensuring the normal progress of processing.

[0007] Preferably, the mixing mechanism includes fixed rods, stirring rods, movable frames, pushing plates, spherical rods, and elliptical rings. The fixed rods are symmetrically fixed on the lower side of the dispersion plate, and stirring rods are evenly fixed on the fixed rods. By driving the stirring rods to rotate through the rotation of the dispersion plate, the mixing and stirring of materials can be achieved.

[0008] Preferably, a movable frame is slidably connected to the fixed rod, a pushing plate is fixed on the movable frame, and the pushing plate is in contact with and slides on the stirring rod. At the same time, both sides of the pushing plate are inclined surface structures. By driving the pushing plate to move left and right through the movable frame, the pushing of materials can be synchronized during the rotational stirring of materials, further ensuring the mixing effect of materials.

[0009] 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. Moreover, the elliptical ring is fixed on the fixed cylinder. When the movable frame rotates, through the sliding action between the spherical rod and the groove on the elliptical ring, a basic acting force can be provided for the reciprocating motion of the movable frame, thereby ensuring the normal operation of the device.

[0010] Preferably, the detection mechanism includes a fixed frame, a cylinder, a sampling port, a discharge port, a rotating rod, a first gear, a second gear, a driving gear, a rotating block, a sampling groove, a mounting rod, and a detection camera. The fixed frame is fixed inside the mixing box, a cylinder is fixed on the fixed frame, a sampling port is opened on the left side of the cylinder, and a discharge port is opened on the front side of the lower end surface of the cylinder. Through the function of the sampling port, sampling of the masterbatch can be achieved, providing a basic guarantee for masterbatch detection to determine whether the materials are mixed completely. In cooperation with the function of the discharge port, the detected materials can fall back automatically conveniently.

[0011] Preferably, a rotating rod is connected to the cylinder by a bearing, a first gear is fixed on the rotating rod, and the first gear meshes with the second gear to achieve transmission. At the same time, the second gear is connected to the mixing box by a bearing. Through the meshing transmission between the first gear and the second gear, a basic acting force can be provided for the rotation of the rotating rod, ensuring the normal operation of the device.

[0012] Preferably, the second gear is meshed with the driving gear, and the driving gear is fixed on the spiral feeding rod. When the driving gear rotates one full circle, the second gear rotates exactly 90°. Through the transmission between the second gear and the driving gear, it can provide a basic guarantee for the rotation of the rotating rod. And by limiting the rotation angle of the second gear, it can provide a basic guarantee for the intermittent rotation of the rotating rod.

[0013] Preferably, a rotating block is fixed at the lower end of the rotating rod, and the rotating block is slidably connected to the cylinder. Four sampling grooves are equiangularly arranged on the rotating block. When the rotating rod rotates, it synchronously drives the rotating block and the sampling grooves to rotate. By the cooperation of the sampling grooves at different positions and the sampling ports, the automatic sampling of the material can be realized, thus providing a basic guarantee for the subsequent material detection.

[0014] Preferably, a mounting rod is fixed on the fixing frame, and a detection camera is installed on the lower end face of the mounting rod. The detection camera can detect the sampled material, and determine whether the material is completely mixed by judging the color and brightness of the material, so as to ensure the production quality of the product.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. For the raw material mixing device for masterbatch processing, a dispersion mechanism with a lifting function is adopted, which can lift the materials deposited at the bottom of the mixing tank upward and disperse them, thereby ensuring the mixing effect of the materials. Specifically, through the action of the motor, the fixed cylinder and the spiral feeding rod, the materials at the bottom of the mixing tank can be lifted upward. When the materials are lifted onto the dispersion plate, due to the rotational centrifugal action of the dispersion plate, the materials are dispersed around, so that the materials are evenly mixed, improving the mixing effect of the materials;

[0017] 2. For the raw material mixing device for masterbatch processing, an interlocking mixing mechanism is adopted, which can realize the multiple stirring and mixing of the materials, thereby improving the mixing efficiency of the materials. Specifically, the rotation of the spiral feeding rod drives the fixed rod, the stirring rod, the movable frame and the pushing plate to rotate. With the horizontal rotation of the stirring rod, the primary mixing and stirring of the materials can be realized. Then, with the sliding between the spherical rod and the elliptical ring, the pushing plate can perform a reciprocating motion, so as to realize the horizontal pushing of the materials in the mixing tank, and then the materials can perform a certain horizontal movement, and then realize the secondary mixing of the materials, ensuring the mixing effect of the materials and improving the mixing efficiency of the materials;

[0018] 3. The raw material mixing device for processing the masterbatch adopts a linkage intermittent sampling and detection mechanism, which can sample and detect the mixed material during the material mixing process, so as to not only determine whether the materials are mixed completely, but also 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 tank through the sampling port. With the cooperation of the driving gear, the second gear and the first gear, the rotating rod, the rotating block and the sampling tank rotate intermittently. When the sampled material rotates under the detection camera, the detection camera detects the color and brightness of the material to determine whether the materials are mixed completely and the mixing quality of the materials.

DETAILED DESCRIPTION OF THE INVENTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1 - 7 , the present invention provides a technical solution: a raw material mixing device for masterbatch processing, including a mixing tank 1 and a motor 2. The motor 2 is fixed on the upper end surface of the mixing tank 1. A dispersion mechanism 3 is installed in the mixing tank 1. The dispersion mechanism 3 is connected to a mixing mechanism 4. A detection mechanism 5 is also installed in the mixing tank 1. The dispersion mechanism 3 includes a fixed cylinder 301, a support rod 302, a spiral feeding rod 303, a dispersion disc 304, a baffle plate 305, a connecting rod 306 and a limiting ring 307. The fixed cylinder 301 is arranged in the mixing tank 1. The fixed cylinder 301 is fixed to the mixing tank 1 through the support rod 302. A spiral feeding rod 303 is arranged in the fixed cylinder 301. The spiral feeding rod 303 is connected to the mixing tank 1 by bearings, and the spiral feeding rod 303 is fixedly connected to the output end of the motor 2. A dispersion disc 304 is fixed on the spiral feeding rod 303. A baffle plate 305 fixed on the spiral feeding rod 303 is arranged above the dispersion disc 304. The baffle plate 305 and the dispersion disc 304 are fixedly connected to each other through the connecting rod 306. A limiting ring 307 is also fixed on the lower end surface of the dispersion disc 304, and the limiting ring 307 is slidably connected to the fixed cylinder 301. By driving the spiral feeding rod 303 to rotate through the motor 2, and with the cooperation of the spiral feeding rod 303 and the fixed cylinder 301, the materials on the lower side in the mixing tank 1 are lifted upward. When the materials are lifted onto the dispersion disc 304, through the rotational centrifugal action of the dispersion disc 304, the materials are dispersed around, so as to uniformly mix the materials.

[0029] An inlet 101 is installed at the upper end of the mixing tank 1, and an outlet valve port 102 is installed at the lower end of the mixing tank 1. And supporting feet 103 are equally angularly installed at the lower end of the mixing tank 1; The mixing mechanism 4 includes a fixed rod 401, a stirring rod 402, a movable frame 403, a pushing plate 404, a spherical rod 405 and an elliptical ring 406. The fixed rods 401 are symmetrically fixed on the lower side of the dispersion disc 304, and stirring rods 402 are uniformly fixed on the fixed rods 401; A movable frame 403 is slidably connected to the fixed rod 401, and a pushing plate 404 is fixed on the movable frame 403. And the pushing plate 404 is in contact with and slides on the stirring rod 402. At the same time, both sides of the pushing plate 404 are inclined plane structures; A spherical rod 405 is also fixed on the movable frame 403, and the spherical rod 405 is nested and slides in the groove on the elliptical ring 406, and the elliptical ring 406 is fixed on the fixed cylinder 301;

[0030] When using the raw material mixing device processed with this masterbatch, such as Figures 1 - 7 shown, first, the materials to be mixed are put into the mixing box 1 through the feeding port 101 according to the proportion. At this time, the discharge valve port 102 is in the closed state. After the materials are put in, the motor 2 is started. The spiral feeding rod 303, the dispersion disk 304 and the baffle plate 305 are driven by the motor 2 to rotate clockwise. When the spiral feeding rod 303 rotates, with the cooperation of the fixed cylinder 301, the materials at the lower side in the mixing box 1 can be lifted upward. When the materials are lifted onto the dispersion disk 304, due to the rotational centrifugal action of the dispersion disk 304, the materials can be dispersed around, which is convenient for material mixing. And when the dispersion disk 304 rotates, the fixed rod 401, the stirring rod 402, the movable frame 403 and the pushing plate 404 are synchronously driven to rotate. Through the rotation of the stirring rod 402, horizontal stirring of the materials can be realized, and primary mixing of the materials is achieved. And when the movable frame 403 rotates, the spherical rod 405 is synchronously driven to rotate. With the sliding cooperation between the spherical rod 405 and the groove on the elliptical ring 406, the elliptical ring 406 and the movable frame 403 can perform an orderly reciprocating motion, thereby driving the pushing plate 404 to move. Through the reciprocating motion of the pushing plate 404, the materials at the inner edge and the middle position in the mixing box 1 can be pushed, so as to ensure the uniformity of material mixing and effectively guarantee the mixing effect of the materials;

[0031] The detection mechanism 5 includes a fixed frame 501, a cylinder 502, a sampling port 503, a blanking port 504, a rotating rod 505, a first gear 506, a second gear 507, a driving gear 508, a rotating block 509, a sampling groove 510, a mounting rod 511 and a detection camera 512. The fixed frame 501 is fixed in the mixing box 1, and a cylinder 502 is fixed on the fixed frame 501. And a sampling port 503 is opened on the left side of the cylinder 502. At the same time, a blanking port 504 is opened on the front side of the lower end surface of the cylinder 502; The rotating rod 505 is connected to the cylinder 502 by a bearing, and a first gear 506 is fixed on the rotating rod 505. And the first gear 506 is engaged with the second gear 507 to realize transmission. At the same time, the second gear 507 is connected to the mixing box 1 by a bearing; 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 when the driving gear 508 rotates one week, the second gear 507 just rotates 90°; The lower end of the rotating rod 505 is fixed with a rotating block 509, and the rotating block 509 is slidably connected with the cylinder 502. And four sampling grooves 510 are equally angled 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;

[0032] During the operation of the device, such as Figures 1 - 7As shown, when the spiral feeding rod 303 rotates, it synchronously drives the rotation of the driving gear 508. Through the transmission among the driving gear 508, the second gear 507 and the first gear 506, the rotating rod 505, the rotating block 509 and the sampling groove 510 perform orderly intermittent rotation. When the sampling groove 510 cooperates with the sampling port 503, a part of the material splashing outward by the centrifugal action of the dispersion disc 304 enters the sampling groove 510 through the sampling port 503 at this time, thus realizing the automatic sampling function of the material. After sampling, the rotating block 509 and the sampling groove 510 can drive the sampled material to move in a clockwise rotation. When the sampled material rotates 180° clockwise, the sample material just moves to directly below the detection camera 512. Through the function of the detection camera 512, the sample material can be detected. By judging the color and brightness of the material to determine whether the material is completely mixed (to ensure the accuracy of the detection data, 5 - 10 detections are required, and the detection interval time is 1min - 2min), the mixing quality of the material can also be detected. After the sample material is detected, the rotating block 509 and the sampling groove 510 continue to rotate, and the sample material can continue to move. When the lower end of the sampling groove 510 cooperates with the blanking port 504, the sample material falls into the mixing box 1 through the blanking port 504, avoiding material waste. This is the working principle of the raw material mixing device for masterbatch processing.
