Description
Technical Field
[0001] This utility model belongs to the field of color masterbatch processing technology, and in particular relates to a homogenization device for color masterbatch processing. Background Technology
[0002] The full name of color masterbatch is color masterbatch, also known as color seed. It is a new type of special coloring agent for polymer materials. Color masterbatch is mainly used in plastics. In the production process of color masterbatch, a homogenization device is required to ensure that the various raw materials of color masterbatch are mixed evenly.
[0003] Utility model patent CN218928280U discloses a homogenizing device for color masterbatch processing with convenient adjustment of stirring height. A rotating shaft is rotatably connected to the top center of the housing. A frame-type stirring blade is fixed to the bottom of the rotating shaft. A driven gear is sleeved on the top of the rotating shaft, and a gear ring meshes with the outer side of the driven gear. The gear ring is fixed to the bottom inner wall of the bushing. A lead screw groove is formed at the bottom of the rotating shaft, and a lead screw is rotatably connected inside the groove. The lead screw meshes with an internal threaded seat sleeved on the rotating shaft. The internal threaded seat is fixed at the center of the frame-type stirring blade. An adjusting head, connected to the lead screw drive, is installed at the top center of the rotating shaft. When the frame-type stirring blade needs adjustment, a tool is used to fix the bushing, and then the tool is used to rotate the adjusting head through the adjusting hole, driving the lead screw to rotate, thereby causing the internal threaded seat to move up and down on the rotating shaft. This achieves convenient, time-saving, and labor-saving adjustment of the frame-type stirring blade position.
[0004] However, the above-mentioned device has the following technical problems in actual use: 1. The above-mentioned device adjusts the height of the stirring blades by rotating the adjusting head, which drives the lead screw to rotate. The lead screw controls the raising and lowering of the internal thread seat. However, the device can only adjust the height of the stirring blades in advance according to the amount of material stored inside the shell during stirring. During use, the stirring blades cannot move up and down automatically, which means that the stirring blades can only stir the material in a specific range when rotating, and cannot stir all the material in the shell, resulting in insufficient stirring effect.
[0005] Second, in addition, the above-mentioned device can only drive the material to turn over and achieve the purpose of mixing by rotating the stirring blade. However, when too much material is piled up, the rotation of the stirring blade cannot completely turn the material over, and the material needs to be mixed for a long time, thus increasing the time required for stirring. Utility Model Content
[0006] This utility model provides a homogenization device for color masterbatch processing, which aims to solve the problems mentioned in the background art, such as the inability of the above-mentioned device to automatically adjust the height of the stirring blade during use, the inability to achieve uniform mixing of materials when the material storage is too large, and the inability of the above-mentioned device to make all the materials turn over by stirring the stirring blade alone when the material storage is too large, which increases the mixing time of the materials.
[0007] This utility model is implemented as follows: a homogenization device for color masterbatch processing includes: a mixing tank with a feed pipe connected to it, and a discharge pipe at the bottom of the mixing tank, on which a discharge valve is fixedly installed; a rotating disk rotatably connected to the top wall of the mixing tank; a connecting seat fixedly connected to the top of the rotating disk; a rotating assembly for driving the rotating disk to rotate horizontally on the mixing tank; an outer cylinder movably installed inside the connecting seat; and a self-adjusting assembly connected to the outer cylinder inside the connecting seat. When the rotating disk rotates, the self-adjusting assembly drives the outer cylinder to reciprocate up and down; and a stirring rod assembly disposed inside the mixing tank. The stirring rod assembly and the outer cylinder are slidably connected, and the outer cylinder is also provided with a locking component for adjusting the height of the stirring rod assembly. In this scheme, the height of the stirring blades in the mixing tank can be pre-adjusted by the locking component before the device starts working, so that the position of the stirring blades and the material in the mixing tank corresponds. Then, when the device starts working, the rotating component controls the rotating disk to rotate, and the rotating disk drives the connecting seat to move. The connecting seat controls the reciprocating up and down movement of the outer cylinder on the mixing tank through the self-adjusting component. The outer cylinder and the stirring rod assembly are connected by the locking component. Therefore, when the outer cylinder moves, it will drive the stirring rod assembly to move synchronously, thereby increasing the stirring range of the stirring blades and improving the mixing efficiency.
[0008] In addition, a return material assembly is provided on one side of the mixing tank in this device. When the material in the mixing tank is being agitated, the material at the bottom will enter the return material box through the feed port and be discharged from the discharge port at the top by the conveying of the screw conveyor. This realizes the circulation of the material in the mixing tank and reduces the mixing time of the material.
[0009] Preferably, the self-adjusting assembly includes: a movable cavity formed within the connecting seat; a rotating groove at the top of the movable cavity that transitions with the outer cylinder; a limiting ring fixedly connected to the outer wall of the outer cylinder within the movable cavity; a spring sleeved on the outer side of the outer cylinder away from the rotating disk; an annular track fixedly connected to the inner circumferential wall of the mixing tank; the annular track having two opposing lifting portions and a sinking portion; and two connecting plates symmetrically fixedly connected to the bottom outer wall of the outer cylinder within the mixing tank; rollers rotatably connected to the ends of the two connecting plates away from the outer cylinder; the rollers rolling on the annular track. In this design, the outer cylinder rotates via two connecting plates and rollers that roll on a circular track. However, this circular track is not a horizontal ring; it has two opposing lifting sections and a lowering section. The two rollers are simultaneously positioned on the lifting section (or the lowering section). When the rollers move to the lifting section, the overall height of the outer cylinder increases. At this time, the outer cylinder drives the limiting ring to rise within the movable cavity and compress the spring, thereby raising the height of the stirring rod assembly. When the rollers move to the lowering section, the spring returns to its original position, and the limiting ring is at the bottom of the movable cavity, reducing the overall height of the outer cylinder and consequently lowering the height of the stirring rod assembly.
[0010] Preferably, two limiting blocks are symmetrically fixedly installed on the inner peripheral wall of the rotating groove, and a limiting groove is vertically formed on the outer wall of the outer cylinder. The limiting groove and the limiting block correspond to each other, and the limiting block is slidably connected in the limiting groove. In this scheme, by setting the limiting groove and the limiting block, the lifting height of the outer cylinder can be limited to prevent the outer cylinder from separating from the connecting seat. On the other hand, when the rotating disk drives the connecting seat to rotate, the connecting seat can transfer the rotational kinetic energy to the outer cylinder through the limiting groove and the limiting block, and use the outer cylinder to drive the stirring rod assembly to rotate.
[0011] Preferably, the stirring rod assembly includes: an inner rod slidably connected to the outer cylinder, a stirring blade fixedly connected to the bottom end of the inner rod inside the mixing tank; the locking assembly includes: at least two through holes symmetrically opened on the top outer wall of the outer cylinder, each through hole being detachably connected to a locking screw; multiple sets of locking holes equally spaced along the height of the inner rod on its outer wall, each set of locking holes having a screw hole corresponding to the number of through holes; the threaded end of the locking screw being threadedly connected to the screw hole. In this embodiment, the stirring rod assembly has an inner rod slidably connected to the outer cylinder, and a stirring blade is provided at the bottom end of the inner rod. The stirring blade is located inside the mixing tank for stirring the material. When it is necessary to adjust the height of the stirring blade, the height of the inner rod is manually adjusted inside the outer cylinder, and after aligning the corresponding screw hole and through hole, the threaded section of the locking screw is inserted into the threaded screw hole to complete the locking and fixing of the inner rod.
[0012] Preferably, the rotating assembly includes: a mounting bracket fixedly installed on the mixing tank, a first motor fixedly connected to the mounting bracket, a gear fixedly connected to the output end of the first motor, and a gear ring arranged around the outer peripheral wall of the rotating disk, the gear ring and the gear meshing together; in this scheme, when the first motor rotates, it drives the rotating disk to rotate through the meshing of the gear and the gear ring, and the rotating disk in turn controls the stirring rod assembly to rotate to achieve stirring of the material.
[0013] Preferably, the outer wall of the mixing tank is further provided with a return material assembly, which includes: a return material box fixedly installed on the side wall of the mixing tank, the return material box and the mixing tank being connected by an outlet and an inlet, the outlet being located above the inlet, a spiral conveyor rod being rotatably connected inside the return material box, and a second motor being fixedly connected to the top wall of the return material box, the second motor being fixedly connected to the end of the spiral conveyor rod; in this scheme, when the device is stirring the material, the output end of the second motor controls the spiral conveyor rod to rotate, and some of the material at the bottom will enter the return material box through the inlet, be conveyed by the spiral conveyor rod and discharged from the outlet at the top and flow back into the mixing tank, completing the circulation of the material, thereby effectively reducing the mixing time of the material.
[0014] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a homogenization device for color masterbatch processing. 1. In this device, the height of the stirring blades in the mixing tank can be pre-adjusted by the locking assembly before the device starts working, so that the position of the stirring blades and the material in the mixing tank corresponds. Then, when the device starts working, the rotating assembly controls the rotating disk to rotate, and the rotating disk drives the connecting seat to move. The connecting seat controls the outer cylinder to reciprocate up and down on the mixing tank through the self-adjusting assembly. The outer cylinder and the stirring rod assembly are connected by the locking assembly. Therefore, when the outer cylinder moves, it will drive the stirring rod assembly to move synchronously, thereby increasing the stirring range of the stirring blades and improving the mixing efficiency.
[0015] 2. In this device, a return material component is provided on one side of the mixing tank. When the material in the mixing tank is being agitated, the material at the bottom will enter the return material box through the feed port and be discharged from the discharge port at the top by the conveying of the screw conveyor. This realizes the circulation of the material in the mixing tank and reduces the mixing time of the material. Attached Figure Description
