Description

Technical Field

[0001] This utility model belongs to the field of color masterbatch processing technology, and in particular relates to a low-temperature grinding device for color masterbatch production. Background Technology

[0002] In the production of color masterbatch, grinding is a key process that determines the uniformity of particle size and subsequent performance. The grinding device used in color masterbatch production is the core equipment to achieve this process. It mainly uses mechanical force to grind the initially formed color masterbatch particles to a fine particle size that meets the production requirements, ensuring that the color masterbatch can be uniformly mixed with the base resin in subsequent injection molding, extrusion and other processing stages, avoiding problems such as color difference or uneven dispersion.

[0003] The core structure of mainstream masterbatch grinding equipment on the market typically includes a fixed grinding component, a rotary grinding component, a power mechanism, a feeding mechanism, and a discharging mechanism. The fixed grinding component is mostly a shell structure with a built-in grinding chamber. The rotary grinding component (such as a grinding disc or grinding roller) is set inside the grinding chamber and is driven to rotate by a motor, forming relative motion with the fixed grinding component to squeeze, shear, and grind the masterbatch entering the grinding chamber. The feeding mechanism is mostly a straight channel structure set at the top or side, and the masterbatch enters the grinding chamber by gravity or simple pushing. The discharging mechanism is mostly set below or to the side of the grinding chamber, and transports the ground masterbatch to the storage structure.

[0004] However, existing masterbatch grinding equipment has the following drawbacks in practical use: First, in existing devices, the rotary grinding assembly is positioned above the fixed grinding assembly, and a discharge pipe is fixed at the lower end of the fixed grinding assembly. However, with this arrangement, the ground masterbatch tends to accumulate between the rotary grinding assembly and the fixed grinding assembly, making it difficult for it to enter the discharge pipe. Second, the feeding channels in existing devices are mostly straight channels without auxiliary pushing structures. The masterbatch falls into the grinding chamber solely by its own gravity. When the masterbatch particles are uneven in size or have poor flowability, they are prone to bridging and accumulation in the feeding channel, resulting in fluctuating feed rates or even feed interruptions. This not only causes instability in the amount of masterbatch in the grinding chamber, leading to over-grinding or under-grinding, but also further affects the particle size uniformity of the final masterbatch, reducing product quality.

[0005] Therefore, it is essential to invent a low-temperature grinding device for the production of color masterbatch. Utility Model Content

[0006] To address the above problems, this utility model proposes a low-temperature grinding device for masterbatch production, and the technical solution used is as follows: A low-temperature grinding device for masterbatch production includes a support leg, a sealed box, a grinding base, a feeding channel, a grinding head, a servo motor, a storage bin, a horn tube, and a cooling mechanism. The upper end of the support leg is bolted to the sealed box, and the upper end of the sealed box is bolted to the grinding base, which has a through feeding channel. The grinding head is located on the lower side of the grinding base and is rotatably connected to the sealed box via a support bearing. The lower end of the grinding head is fixed to the output end of the servo motor, whose base is bolted to the sealed box. A horn tube is fixed to the upper end of the sealed box, and its lower end communicates with the feeding channel. A storage bin is located on the lower side of the grinding head and is slidably installed inside the sealed box. A cooling mechanism is bolted to the outer side of the sealed box, and its output end communicates with the interior of the sealed box. Both the servo motor and the cooling mechanism are electrically connected to an external production computer via data cables.

[0007] Furthermore, the grinding head includes a rotating column and a grinding block. The lower end of the rotating column is rotatably mounted inside the sealed box via a support bearing, and the lower end of the rotating column is fixed to the output end of the servo motor. The upper end of the rotating column is fixed with a grinding block by bolts. This configuration allows the rotating block to rotate accordingly under the drive of the servo motor, thereby grinding the masterbatch that enters between the grinding head and the grinding seat.

[0008] Furthermore, the grinding head also includes a column and a spiral blade. The column is fixed to the upper end of the grinding block by bolts and is movably disposed inside the feeding channel. The spiral blade is fixed to the outer side of the column by welding. This arrangement can push the masterbatch inside the feeding channel and prevent the masterbatch from accumulating inside the feeding channel.

[0009] Furthermore, the storage box includes a box body, a handle, a groove, and a sleeve. Two boxes are provided, and the boxes are mirror images of each other. Each box body is slidably connected to a sealed box, and the handle is fixed to the outer end of each box body by bolts. A groove adapted to the rotating column is opened at a corresponding position on the box body. The outer side of the rotating column inside the groove is rotatably mounted with a sleeve through a support bearing. This arrangement allows the box body to temporarily store the ground masterbatch. At the same time, the cooperation of the groove and the sleeve can prevent the rotation of the rotating column from affecting the box body.

[0010] Furthermore, the cooling mechanism includes an air pump, a compressor, a first air supply pipe, and a second air supply pipe. Both the air pump and the compressor are fixed to the outer side of the sealed box with bolts, and the output end of the air pump is fixed to the input end of the compressor through the first air supply pipe. The output end of the compressor is connected to the inside of the sealed box through the second air supply pipe. Both the air pump and the compressor are electrically connected to an external production computer through a data cable. With this configuration, the air pump can deliver external gas to the inside of the compressor, where the gas is cooled and then discharged into the inside of the sealed box through the second air supply pipe.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the grinding seat is located on the upper side of the grinding head. Therefore, the masterbatch that has been ground by the grinding seat and the grinding head will fall directly into the storage box, thus preventing material discharge blockage. The grinding head of this invention is designed to rotate under the drive of a servo motor, thereby grinding the masterbatch that enters between the grinding head and the grinding base. In addition, the column can rotate with the grinding block, thereby driving the spiral blades to push the masterbatch inside the feeding channel, thus preventing the masterbatch from accumulating inside the feeding channel.

[0025] Please see Figure 1-4 As shown, this utility model is a low-temperature grinding device for color masterbatch production, and its working principle is as follows: Feeding process: The masterbatch enters the feeding channel 4 through the horn tube 8.

Cooling process: The air pump 91 delivers external gas to the compressor 92. After the gas is cooled in the compressor 92, it is discharged into the sealed box 2 through the second air supply pipe 94 to reduce the temperature inside the sealed box 2 and prevent the performance of the masterbatch from changing due to frictional heat during the grinding process. Discharge process: The ground masterbatch falls into the storage box 7. By pulling the handle 72 of the storage box 7, the storage box 7 can be pulled out from the sealed box 2 and the ground masterbatch can be taken out.
