Abstract
Description
Technical Field
[0001] This utility model belongs to the field of color masterbatch pulverization technology, and more specifically, it relates to a color masterbatch ultrafine pulverization device. Background Technology
[0002] When crushing color masterbatch raw materials, toothed disc crushers are mostly used. The toothed disc crusher can shear and impact the material through the high-speed rotating toothed disc, thereby crushing the color masterbatch raw materials to the micron level. After crushing is completed, the main shaft motor can only be turned off after all the material in the crushing chamber has been discharged.
[0003] For example, CN221156850U discloses a pulverizing device for color masterbatch, including a pulverizing box, a first pulverizing component, a second pulverizing component, a filter frame, and a vibrating element. Color masterbatch is added into the pulverizing box through the feed inlet. The color masterbatch undergoes a first pulverization between two first pulverizing rollers, and then undergoes a second pulverization between two rotating second pulverizing rollers. After two pulverizations, the color masterbatch falls into the filter frame. The vibrating element drives the screen to vibrate, filtering the pulverized color masterbatch again. The particles fall through the screen holes and are discharged from the outlet. Larger particles remain in the filter frame. When pulverization stops, the filter frame is pulled out of the U-shaped groove, and the larger color masterbatch is poured into a collection box for unified collection. Then, the filter frame is inserted into the U-shaped groove through the insertion port, and the color masterbatch pulverization can be carried out again. By pulverizing the color masterbatch twice and then filtering it through the filter frame, the pulverization effect of the color masterbatch is improved.
[0004] Based on the above, most existing crushers are manually shut down, requiring staff to judge whether the material has been completely discharged based on their experience. This is prone to errors, resulting in residues of previous batches of material remaining in the crushing chamber, causing color deviations in subsequent products and affecting the crusher's performance. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides an ultrafine pulverizing device for color masterbatch. This solves the problem that most existing pulverizers are manually shut down, requiring operators to rely on their experience to determine whether the material has been completely discharged. This can easily lead to errors in judgment, resulting in residues of previous batches of material remaining in the pulverizing chamber, causing color deviations in subsequent products and affecting the pulverizer's performance.
[0006] The purpose and effectiveness of this utility model's ultrafine pulverization equipment for masterbatch are achieved through the following specific technical means:

[0009] Furthermore, the transmission structure also includes a reciprocating self-locking drive and a limiting connecting rod; the reciprocating self-locking drive is bolted to the right side of the conical feed hopper; the limiting connecting rod is fixedly connected to the outside of the output shaft of the reciprocating self-locking drive, the limiting connecting rod is hinged to the transmission connecting rod, and the control circuit of the reciprocating self-locking drive is connected in series with the control circuit of the microwave level sensor.
[0010] Furthermore, the cleaning structure includes a closed shielding ring and a position limiting ring; the closed shielding ring is fixedly connected to the lower part of the wind power transmission pipe; and the position limiting ring is fixedly connected to the upper part of the wind power transmission pipe.
[0011] Furthermore, the cleaning structure also includes a sliding connecting frame, a reset elastic element, and a sealing baffle plate; the sliding connecting frame is slidably connected to the inner side of the wind power transmission pipe; the sliding connecting frame is elastically connected to the position limiting ring through the reset elastic element; the sealing baffle plate is fixedly connected to the lower part of the sliding connecting frame, and the sealing baffle plate is inserted into the inner side of the sealing baffle ring.
[0012] Furthermore, the cleaning structure also includes metal limiting plates and limiting electromagnets; two metal limiting plates are provided, and the two metal limiting plates are respectively fixedly connected to the front and rear sides of the sliding connecting frame; two limiting electromagnets are provided, and the two limiting electromagnets are respectively fixedly connected to the front and rear sides of the wind power conveying pipe; a fan is provided at the rear of the wind power conveying pipe, and the control circuits of the two limiting electromagnets are connected in series with the control circuit of the fan.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This invention utilizes a microwave level sensor and a rotary paddle level switch to detect material levels and automatically shut down the crusher. This effectively ensures that all material is discharged from the crusher, avoiding errors caused by manual operation, preventing residue from previous batches in the crushing chamber, and preventing color deviations in subsequent products. This ensures the crusher's performance. The automatic opening and closing of the impurity blocking cover prevents impurities from falling into the crusher after shutdown and also prevents materials from being mistakenly added to a crusher that is not running. The V-shaped air guide hole ensures that airflow reaches the detection head of the microwave level sensor, effectively preventing material powder from covering the detection head and affecting the accuracy of the detection results. The movement of the sealing baffle keeps the pneumatic conveying pipe closed when there is no airflow, preventing material from entering the pneumatic conveying pipe and causing waste.
