[0015] The present invention provides a bisphenol AF material dust prevention device, which has the following beneficial effects:

[0016] (1) The present invention allows bisphenol AF to remain stationary inside a distribution funnel and to flow out slowly through the opening of the distribution funnel, so that bisphenol AF does not generate dust when it is discharged. This prevents the dust generated by bisphenol AF during rapid discharge from mixing with certain chemical dusts that may be flammable or toxic, thereby reducing the risk of explosion and poisoning. When bisphenol AF is discharged, the size of the feed opening is controlled in real time according to the amount of bisphenol AF in the distribution funnel, so as to prevent excessive bisphenol AF from accumulating inside the feed frame, which would result in failure to achieve the expected dust prevention effect, thereby ensuring the stability of the device during operation.

[0017] (2) According to the present invention, after the bisphenol AF is weighed and classified by rotating the rotating plate, it will flow to the discharge port, so that when the discharge is completed, the bisphenol AF will be weighed and divided according to the weight of each portion set in advance, which is convenient for the subsequent secondary processing of the bisphenol AF and improves the production efficiency. The resetting of the dividing frame will produce a slight shake, so that the accumulated bisphenol AF inside the dividing frame will be flattened by the shaking, preventing the accumulation of bisphenol AF from causing errors in weight measurement between some areas, causing the weight detector to be activated before the required weight is reached, thereby improving the practicality of the device. The bottom of the dividing funnel will be blocked by the movement of the sealing plate, preventing the bisphenol AF inside the dividing funnel from flowing to the conveying device when the rotating plate is opened, causing weight deviation, thereby improving the accuracy of the equipment during operation.

[0018] (3) The invention can scrape off the bisphenol AF remaining at the bottom of the feed frame by moving the scraper plate, thereby preventing the bisphenol AF from losing its use value after being retained for a long time and causing property damage. The scraper plate moves toward the top and moves away from the discharge port through the limit rod, so that the scraper plate will not contact the inner wall of the feed frame when moving away from the discharge port, preventing the scraper plate from scraping the falling bisphenol AF away from the discharge port when moving in the reverse direction, thereby ensuring the stable operation of the material distribution device and improving practicality.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 7, one embodiment of the present invention is: a bisphenol AF unloading dust prevention device, comprising a conveying device 1, both ends of the conveying device 1 are fixedly installed with a bearing plate 2, a rotating motor 3 is fixedly installed on the surface of the conveying device 1, and a supporting foot 4 is fixedly installed on the bottom of the bearing plate 2. A transport device is arranged on the top of the conveying device 1, and the transport device comprises: a vertical rod 51, a feed frame 52, a top cover 53, a partition plate 54, a material distribution funnel 55, a shift block 56, a material blocking plate 57, a wire fixer 58, a steel cable 59 and a No. 1 spring 510, the vertical rods 51 are fixedly installed on the top of the bearing plate 2, the feed frame 52 is fixedly installed between the vertical rods 51, a discharge port is opened at the bottom of the feed frame 52, a top cover 53 is fixedly installed on the top of the feed frame 52, a feed port is opened on the surface of the top cover 53, a partition plate 54 is fixedly installed inside the feed frame 52, a No. 1 spring 510 is fixedly installed on the top of the partition plate 54, and a material distribution funnel 55 is fixedly installed on the top of the partition plate 54. The hopper 55 is connected to the partition plate 54 through a No. 1 spring 510, so that no dust is generated when bisphenol AF is discharged, and the dust generated when bisphenol AF is quickly discharged is prevented from being flammable or toxic with certain chemical dusts, which can reduce the risk of explosion and poisoning. The shifting block 56 is fixedly installed at the bottom of the distribution funnel 55, the baffle plate 57 is slidably installed at the bottom of the top cover 53, the wire fixer 58 is fixedly installed at the bottom of the top cover 53, and the steel cable 59 is slidably installed on the inner wall of the wire fixer 58. One end of the steel cable 59 is fixedly installed on the top of the distribution funnel 55, and the other end of the steel cable 59 is fixedly installed on the surface of the baffle plate 57. When bisphenol AF is discharged, the size of the feed port can be controlled in real time according to the amount of bisphenol AF in the distribution funnel 55 to prevent excessive bisphenol AF from accumulating inside the feed frame 52, which will result in failure to achieve the expected dust prevention effect, thereby ensuring the stability of the device during operation.

[0029] A No. 2 spring is provided between the baffle plate 57 and the top cover 53 , and the material distribution funnel 55 is in contact with the partition plate 54 , and the No. 2 spring drives the baffle plate 57 to reset.

[0030] When this embodiment is working: bisphenol AF enters the interior of the feed frame 52 through the feed port, bisphenol AF falls into the distribution funnel 55 and flows to the bottom, gradually flows out of the feed frame 52, and falls to the top of the conveying device 1 for transportation. Bisphenol AF is allowed to stand still inside the distribution funnel 55 and slowly flows out through the opening of the distribution funnel 55, so that bisphenol AF does not generate dust when it is unloaded, and the dust generated by bisphenol AF during rapid unloading is prevented from being flammable or toxic with certain chemical dusts, which can reduce the risk of explosion and poisoning. When too much bisphenol AF is stored in the distribution funnel 55 and cannot be transported to the bottom in time, the weight of the distribution funnel 55 increases due to the excessive accumulation of bisphenol AF in the distribution funnel 55. After the weight of the distribution funnel 55 increases, it will move toward the bottom. The movement of the distribution funnel 55 to the bottom will drive one end of the steel cable 59 to move toward the bottom. When one end of the steel cable 59 moves toward the bottom, it is affected by the wire fixer 58, which will cause the other end of the steel cable 59 to move toward the direction of the wire fixer 58. The movement of the other end of the steel cable 59 will drive the baffle plate 57 to move toward the direction of the feed port. The movement of the baffle plate 57 will block the feed port. When there is no bisphenol AF inside the distribution funnel 55, the distribution funnel 55 is driven to move toward the top through the reset of the No. 1 spring 510. The movement of the distribution funnel 55 toward the top will drive one end of the steel cable 59 to move toward the top. The baffle plate 57 is driven to move away from the feed port through the reset of the No. 2 spring. When bisphenol AF is discharged, the size of the feed port is controlled in real time according to the amount of bisphenol AF in the distribution funnel 55 to prevent excessive bisphenol AF from accumulating inside the feed frame 52, which will cause the expected dustproof effect to fail to be achieved, thereby ensuring the stability of the device during operation.

[0031] See also Figure 1-Figure 7On the basis of the above embodiment, in another embodiment of the present invention, a material dividing device and a material discharging device are arranged on the top of the conveying device 1, wherein the material dividing device comprises: a material dividing frame 61, a cover plate 62, a reset telescopic rod 63, a rotating plate 64, a weight detector 65 and a transmission block 611, the reset telescopic rod 63 is fixedly mounted on the bottom of the partition plate 54, the cover plate 62 is fixedly mounted on the bottom of the free end of the reset telescopic rod 63, the material dividing frame 61 is fixedly mounted on the bottom of the cover plate 62, the rotating plate 64 is rotatably mounted on the bottom of the material dividing frame 61, the weight detector 65 is fixedly mounted on the bottom of the cover plate 62, and the weight detector 65 is fixedly mounted on the bottom of the cover plate 62.

The transmission block 611 is fixedly installed on the bottom of the cover plate 62, so that the accumulated bisphenol AF inside the dividing frame 61 can be flattened by shaking, so as to prevent the accumulation of bisphenol AF from causing errors in the weight measurement between some areas, resulting in the activation of the weight detector 65 before the required weight is reached, thereby improving the practicality of the device.

[0032] The material distribution device also includes: a square block 66, a sliding rod 67, a long rod 68 and a sealing plate 69. The square block 66 is fixedly installed on the bottom of the rotating plate 64, the sliding rod 67 is slidably installed on the surface of the material distribution frame 61, the long rod 68 is slidably installed on the top of the cover plate 62, and the sealing plate 69 is fixedly installed on the end of the long rod 68 away from the sliding rod 67 to prevent the bisphenol AF inside the material distribution funnel 55 from flowing to the conveying device 1 when the rotating plate 64 is opened, causing weight deviation, thereby improving the accuracy of the equipment during operation.

[0033] A No. 3 spring 610 is provided between the cover plate 62 and the partition plate 54 , and the transmission block 611 is in contact with the shift block 56 , and the No. 3 spring 610 drives the cover plate 62 to reset.

[0035] The discharging device includes: a fixed rod 71, a scraper plate 72, a spring piece 73, a connecting rod 74, a limit rod 75, an arc rod 76 and a limit block 77. The fixed rod 71 is slidably mounted on the inner wall of the feed frame 52, the scraper plate 72 is slidably mounted on the surface of the fixed rod 71, and the spring piece 73 is fixedly mounted on the top of the fixed rod 71 to prevent bisphenol AF from losing its own use value after being retained for a long time and causing property loss. The connecting rod 74 is fixedly mounted on the inner wall of the feed frame 52, the limit rod 75 is fixedly mounted on the end of the connecting rod 74 away from the feed frame 52, the arc rod 76 is rotatably mounted on the surface of the limit rod 75, and the limit block 77 is fixedly mounted on the bottom of the limit rod 75, so that the scraper plate 72 will not contact the inner wall of the feed frame 52 when moving in the direction away from the discharge port, so as to prevent the scraper plate 72 from scraping the falling bisphenol AF away from the discharge port when moving in the reverse direction, thereby ensuring the stable operation of the distributing device and improving practicality.

[0036] A torsion spring is arranged between the arc rod 76 and the limit rod 75, the scraper plate 72 contacts the arc rod 76, and a No. 5 spring is arranged between the fixed rod 71 and the feed frame 52. The arc rod 76 is reset by the torsion spring, and the fixed rod 71 is reset by the No. 5 spring.

[0037] When the present embodiment is working, bisphenol AF flows out of the distributing funnel 55 and enters the inside of the distributing frame 61. When enough bisphenol AF is accumulated inside the distributing frame 61, the detection device will start the control device, and the control device will start the rotating plate 64 to rotate. After the rotating plate 64 rotates, the weighed and classified bisphenol AF will flow to the discharge port, so that when the discharging is completed, the bisphenol AF will be weighed and distributed according to the weight of each portion set in advance, which is convenient for the subsequent secondary processing of bisphenol AF and improves the production efficiency. The movement of the distributing funnel 55 to the bottom will drive the shifting block 56 to move to the bottom. When the shifting block 56 moves to the bottom, it will contact the transmission block 611. The movement of the shifting block 56 to the bottom will push the transmission block 611 to move away from the distributing funnel 55, and the distributing frame 61 will be reset by the No. 3 spring 610. The resetting of the material frame 61 will produce a slight shake, so that the accumulated bisphenol AF inside the material distribution frame 61 is smoothed by the shake, thereby preventing the accumulation of bisphenol AF from causing errors in weight measurement between some areas, causing the weight detector 65 to be activated before the required weight is reached, thereby improving the practicality of the device; the rotation of the rotating plate 64 will drive the square block 66 to rotate, and the rotation of the square block 66 will push the sliding rod 67 to move to the top, and the sliding rod 67 will move to the bottom and contact with the long rod 68, and the movement of the sliding rod 67 will push the long rod 68 to move toward the direction of the distribution funnel 55, and the movement of the long rod 68 will drive the sealing plate 69 to move, and the movement of the sealing plate 69 will block the bottom of the distribution funnel 55, thereby preventing the bisphenol AF inside the distribution funnel 55 from flowing to the conveying device 1 when the rotating plate 64 is opened, causing weight deviation, thereby improving the accuracy of the equipment when it is working.

[0038] The rotation of rotating plate 64 will contact spring piece 73, and the rotation of rotating plate 64 will push spring piece 73 to move toward the top, and the movement of spring piece 73 toward the top will drive fixed rod 71 to move toward the top, and the movement of fixed rod 71 toward the top will drive scraper plate 72 to move toward the top, and after scraper plate 72 moves toward the top, the fixed rod 71 is reset by No. 5 spring and moves toward the direction of the discharge port, and the movement of fixed rod 71 will drive scraper plate 72 to move toward the direction of the discharge port, and the movement of scraper plate 72 will scrape off bisphenol AF remaining at the bottom of feed frame 52 to prevent bisphenol AF from losing its use value after being retained for a long time and causing property loss, and when scraper plate 72 moves toward the direction of the discharge port, scraper plate 72 will push arc rod 76 to rotate toward the top, and The torsion spring is then reset to drive the arc rod 76 to rotate toward the bottom. When the scraper plate 72 moves in the direction away from the discharge port, the scraper plate 72 will contact the arc rod 76, and the arc rod 76 is blocked by the limit block 77, so that the arc rod 76 cannot rotate toward the bottom. When the scraper plate 72 moves in the direction away from the discharge port, it is affected by the arc design of the arc rod 76 itself, and the scraper plate 72 moves to the top, and moves in the direction away from the discharge port through the limit rod 75, so that the scraper plate 72 will not contact the inner wall of the feed frame 52 when moving in the direction away from the discharge port, preventing the scraper plate 72 from scraping the falling bisphenol AF away from the discharge port when it moves in the opposite direction, thereby ensuring the stable operation of the dispensing device and improving practicality.
