[0001] This utility model belongs to the technical field of feeding equipment, specifically relating to a screen lifting and feeding device. Background Technology

[0002] In the food and pharmaceutical production sectors, the screening and feeding processes for tablets, capsules, and small solid materials require a great deal of manual assistance, making it impossible to achieve continuous and fully automated screening and feeding, resulting in low production efficiency. Utility Model Content

[0003] This disclosure aims to at least partially address one of the technical problems in the related art.

[0004] Therefore, the technical solution adopted by this utility model is: a screening and lifting feeding device, including a movable hopper mechanism, a screening mechanism, and a screw lifting feeding mechanism. Material in the movable hopper mechanism enters the screening mechanism for screening and is then fed into the lifting feeding mechanism. The lifting feeding mechanism includes a small hopper, a screw module, a servo motor, a fixed plate, a tilting support rod, a tilting block, a tilting block fixing bracket, a tilting fixing shaft, two hopper tilting connecting seats, an anti-impact block, bearings, and a hopper support plate. The servo motor drives the slider of the screw module to reciprocate on the guide rail of the screw module. The fixed plate is installed on the slider of the screw module. The two hopper tilting connecting seats are respectively installed on the lower side of the small hopper. The two ends of the flipping fixed shaft are rotatably mounted on two hopper flipping connecting seats.

[0019] like Figures 1 to 7As shown, a material lifting and feeding device includes a movable hopper mechanism 1, a screening mechanism 2, and a screw lifting and feeding mechanism 3. Material in the movable hopper mechanism 1 is screened by the screening mechanism 2 and then fed into the lifting and feeding mechanism 3. The lifting and feeding mechanism 3 includes a small hopper 301, a screw module 302, a servo motor 303, a fixed plate 304, a tilting support rod 305, a tilting block 306, a tilting block fixing bracket 307, a tilting fixing shaft 308, two hopper tilting connecting seats 309, an anti-impact block 3010, a bearing 3011, and a hopper support plate 3012. The servo motor 303 drives the slider of the screw module 302 to reciprocate on the guide rail of the screw module 302. The fixed plate 304 is installed on the slider of the screw module 302. The two hopper tilting connecting seats 309 are respectively installed at both ends of the lower part of one side of the small hopper 301. The two ends of the tilting fixing shaft 308 are respectively rotated and mounted on the slider. The two hopper flipping connecting seats 309 are mounted on the flipping fixed shaft 308 and the hopper support plate 3012 are respectively set on both sides below the small hopper 301. The flipping fixed shaft 308 is rotatably connected to the fixed plate 304. The flipping block fixing bracket 307 is mounted on the guide rail of the screw module 302. The flipping block 306 is mounted on the flipping block fixing bracket 307. One end of the flipping support rod 305 is connected to the small hopper 301, and the other end is connected to the bearing 3011. The bearing 3011 can rotate freely on the flipping support rod 305. The small hopper 301 moves upward under the action of the slider of the screw module 302. When the bearing 3011 contacts the flipping block 306, the flipping block 306 blocks the bearing 3011, thereby preventing the bearing 3011 from continuing to move upward, thus enabling the small hopper 301 to flip. The anti-impact block 3010 is mounted on the guide rail of the screw module 302 and is located above the small hopper 301.

[0020] The screening mechanism 2 includes a discharge box 205, a baffle 206, a photoelectric switch 207, a cylinder 209, and a perforated screen 202 and a strip screen 203 installed on the vibrating machine 201. The feed end of the strip screen 203 is located below the perforated screen 202. A buffer box 204 is installed below the strip screen 203. The feed inlet of the discharge box 205 is located below the discharge end of the strip screen 203. The discharge inlet of the discharge box 205 is connected to the feed inlet of the small hopper 301. The photoelectric switch 207 is used to monitor whether the material in the small hopper 301 is full. The baffle 206 is connected to the telescopic rod of the cylinder 209. When the telescopic rod of the cylinder 209 extends, the baffle 206 can block the discharge inlet of the discharge box 205.

[0021] The discharge box 205 is set at an angle.

[0022] The buffer box 204 is connected to the waste collection box 208.

[0023] The movable hopper mechanism 1 includes a circular hopper 101, a insert plate 102, a movable frame 103, and a telescopic adjusting pipe 104. The circular hopper 101 is mounted on the movable frame 103. The insert plate 102 is reciprocally inserted through the outlet of the circular hopper 101. The telescopic adjusting pipe 104 is connected to the outlet of the circular hopper 101. The perforated screen 202 is located below the telescopic adjusting pipe 104.

[0024] The rotating fixed shaft connects the small hopper to it via rotating connecting seats at both ends, allowing the small hopper to rotate around the rotating fixed shaft. Behind the hopper, a hopper support plate is fixed to the fixed plate to support the small hopper and prevent it from rotating downwards and falling. The small hopper has a rotating support rod with a bearing at its front end. The rotating block is fixed to the rotating fixed bracket, which is mounted on the screw module and is adjustable up and down. When the small hopper moves upwards with the slider of the screw module, the bearing at the front end of the rotating support rod touches the rotating block, causing the bearing to rotate. The fixed plate continues to move upwards, and the hopper, passing the rotating block and rotating around the rotating fixed shaft, slowly rotates. When the hopper plane is perpendicular to the ground, the screw module stops, and all the material in the small hopper is poured out. Finally, the servo motor reverses, the fixed plate moves downwards, the hopper rotates back, falls onto the hopper support plate, and returns to its origin, completing one feeding cycle. At the top, there is an anti-impact block, which is a safety device to prevent the lead screw module from running upwards without stopping due to inaccurate signals.

[0025] The movable hopper mechanism is designed for convenient material handling by the customer, allowing it to be moved to the designated material receiving location. When retrieving material, the insert plate can be inserted to prevent material from falling from below. The telescopic adjusting tube allows for vertical adjustment of the distance between itself and the perforated screen, enabling control over the conveying volume during vertical vibration and more efficiently removing duplicate materials, shriveled materials, and other defects.

[0026] When the screening mechanism is working, the material falls into the perforated screen, which can retain oversized or lumpy materials. Then the material enters the bar screen, which screens the debris and shriveled materials into the buffer box. The material is then conveyed to the waste collection box by vibration for collection. Good material passes through the bar screen and enters the discharge box, and finally enters the small hopper for collection. When the photoelectric switch senses that the small hopper is full, the photoelectric switch sends a signal to the host, the host sends a signal to the controller, and the controller stops the linear vibrator from feeding. Then it sends a command to the cylinder, which causes the baffle at the front of the discharge box to extend upward through the cylinder, blocking the discharge port and preventing the material from entering the small hopper or falling onto the table.
