The above-mentioned scheme solves the problem that the existing screening effect and efficiency of raw materials through the screen are relatively low, and the processing requirements of high-quality and high-efficiency degradable polyurethane cannot be met.
[0027] According to this specific embodiment, the screening box 101 has a feed port 117, a debris discharge port 118 and a discharge port 119. The plurality of support legs 102 are fixedly connected to the screening box 101 and are located below the screening box 101. The screening module is arranged in the screening box 101. The raw materials are added through the feed port 117, and then the raw materials slide down through the feed port 117 into the screening box 101. The raw materials are screened by the screening module, and the fine impurities in the raw materials are discharged through the debris discharge port 118. The completely screened raw materials are discharged through the discharge port 119.
[0028] First, the two sliding sleeves 103 are fixedly connected to the screening box 101 and are located on the inner wall of the screening box 101, the two sliding rods 104 are movably connected to the corresponding sliding sleeves 103, the movable frame 105 is fixedly connected to the two sliding rods 104, the rack 106 is fixedly connected to the movable frame 105 and is located on the inner side wall of the movable frame 105, the driving member is arranged on the screening box 101, the fan gear 107 is connected to the driving member and is located in the movable frame 105, and the fan gear 107 is meshed with the rack 106, the toggle frame 110 is fixedly connected to the movable frame 105 and is located below the movable frame 105, the first screen 111 is fixedly connected to the screening box 101 and is located in the screening box 101, the secondary screening unit is arranged below the first screen 111 and is connected to the discharge port 119, when the raw material is fed into the screening box 101, the second screening unit is connected to the second screening unit, and is connected to the discharge port 119. When screening and removing impurities, the raw materials are added through the feed port 117, and then the raw materials slide down through the feed port 117 to the top of the first screen 111, and then the driving member is started, and the driving member drives the fan gear 107 to rotate back and forth. Since the fan gear 107 is meshed with the rack 106 for transmission, the sliding rods 104 at both ends of the movable frame 105 will slide in the sliding sleeve 103 respectively, and drive the lower shifting frame 110 to shift the raw materials on the first screen 111, so that larger impurities in the raw materials remain on the first screen 111, and the raw materials and fine impurities will be screened by the secondary screening unit, and the fine impurities in the raw materials will be discharged through the impurity discharge port 118, and the completely screened raw materials will be discharged through the discharge port 119. In this way, the effect and efficiency of raw material screening can be improved, and the high-quality and high-efficiency biodegradable polyurethane processing requirements can be met.
[0029] Among them, one end of the second screen 112 is located at the discharge port 119, and the two ends of each of the limit springs 114 are fixedly connected to the screening box 101 and the second screen 112 respectively. The vibration motor 113 is arranged below the second screen 112, and the raw materials after the initial screening will fall on the second screen 112. By starting the vibration motor 113, the vibration motor 113 drives the second screen 112 to have the effect of frequency vibration screening, and the limit springs 114 can play the effect of supporting the second screen 112.
[0030] Secondly, the motor base 108 is fixedly connected to the screening box 101 and is located on the outer side wall of the screening box 101. The drive motor 109 is fixedly connected to the motor base 108 and is located above the motor base 108. The output end of the drive motor 109 is connected to the sector gear 107. The motor base 108 fixedly supports the drive motor 109 on the outer wall of the screening box 101, and the output end of the drive motor 109 is movable within the sector gear 107 in the movable frame 105.
[0031] Meanwhile, both of the two suction fans 116 are fixedly connected to the screening box 101 and are both located above the screening box 101. The input ends of both of the two suction fans 116 are communicated with the screening box 101. By arranging the suction fans 116 above the screening box 101, the dust generated during the raw material screening process can be absorbed and processed by the suction fans 116.
[0032] In addition, the observation window 115 is fixedly connected to the screening box 101 and is located on the screening box 101. By means of the observation window 115, it is convenient to understand the screening situation of the raw materials on the first screen 111.
[0033] When screening and removing impurities from the raw materials, the raw materials are added through the feed inlet 117. Subsequently, the raw materials slide down through the feed inlet 117 to the upper side of the first screen 111. Then, the drive motor 109 on the motor base 108 is started. The drive motor 109 drives the sector gear 107 to rotate reciprocally left and right. Since the sector gear 107 is in meshing transmission with the rack 106, at this time, the slide bars 104 at both ends of the movable frame 105 will slide in the sliding sleeves 103 respectively, and drive the lower dialing frame 110 to dial the raw materials on the first screen 111, so that the larger impurities in the raw materials remain on the first screen 111. At the same time, the suction fans 116 can absorb and process the dust generated during the raw material screening process. The raw materials and the fine impurities will fall above the second screen 112. By starting the vibration motor 113, the vibration motor 113 drives the second screen 112 to vibrate with a frequency for screening. The fine impurities in the raw materials will be discharged through the impurity discharge port 118, and the completely screened raw materials will be discharged through the discharge port 119. Through the above method, the effect and efficiency of raw material screening can be improved, meeting the processing requirements of high-quality and high-efficiency degradable polyurethane.
