[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0033] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0034] The utility model is further described below in conjunction with the accompanying drawings:

[0035] like Figure 1-Figure 11 As shown, a succinic anhydride product unloading and filling device includes a storage barrel 1, which is used to temporarily store succinic anhydride products. The storage barrel 1 is supported by a bracket, which is fixed on the ground. A material equalizing pipe 101 is fixedly connected to the bottom of the storage barrel 1, and three equidistantly distributed filling pipes 102 are fixedly connected to the bottom of the material equalizing pipe 101. A material equalizing mechanism 6 for conveying materials to the three filling pipes 102 is arranged in the material equalizing pipe 101. Three packaging bags can be filled simultaneously through the three filling pipes 102. A conveyor belt 7 is arranged under the filling pipe 102 for conveying packaging bags to reduce manual labor.

[0036] A columnar material discharging shell 2 is rotatably installed inside the dispensing tube 102. The material discharging shell 2 includes two symmetrically arranged arc plates 201. The front and rear sides of the arc plates 201 are respectively connected with a front cover plate 202 and a rear cover plate 203 by screws. The front cover plate 202 and the rear cover plate 203 are respectively the front wall and the rear wall of the material discharging shell 2. The front cover plate 202 and the rear cover plate 203 are rotatably connected to the front and rear walls of the dispensing tube 102. The arc plate 201 fits the inner wall of the dispensing tube 102. The front cover plate 202 penetrates the front side wall of the dispensing tube 102. Two symmetrically arranged material boxes 3 are fixedly connected inside the dispensing shell 2. The material box 3 is U-shaped. The inside of the dispensing tube 102 is filled with liquid. The channel is blocked so that the succinic anhydride product will not fall directly out of the filling tube 102. After entering the filling tube 102, the succinic anhydride product will fall into the material box 3. A power mechanism 5 is provided on the rear side of the filling tube 102. The power mechanism 5 is used to simultaneously drive the three material discharge shells 2 to rotate, and the material box 3 is driven to rotate through the material discharge shell 2. When the material box 3 rotates from the top to the bottom, the succinic anhydride product in the material box 3 falls out from the lower opening of the filling tube 102, so that the three filling tubes 102 are discharged synchronously. Since the capacity of the material box 3 is fixed, the single discharge amount of the filling tube 102 is fixed. By controlling the number of rotations of the material discharge shell 2, the filling amount of the packaging bag can be determined.

[0037] A filling block 301 is slidably installed in the material box 3. By adjusting the position of the filling block 301 inside the material box 3, the capacity of the material box 3 can be adjusted, and the capacity of the material box 3 in the three filling tubes 102 can be adjusted respectively, so that the three filling tubes 102 can be simultaneously unloaded with different unloading amounts, thereby meeting the simultaneous unloading of packaging bags of three specifications. The filling block 301 penetrates the front wall of the unloading shell 2, that is, the filling block 301 penetrates the front cover plate 202, so that the unloading shell 2 will drive the filling block 301 to make a circle. The two filling blocks 301 are fixedly connected with an adjusting plate 302, the adjusting plate 302 is located in front of the material discharging shell 2, the adjusting plate 302 is internally threadedly connected with a screw rod 303, the screw rod 303 is rotatably connected to the material discharging shell 2, that is, the screw rod 303 is rotatably connected to the front cover plate 202, and two cleaning mechanisms 4 for vibrating the material box 3 are arranged inside the material discharging shell 2, and the two cleaning mechanisms 4 correspond to the two material boxes 3 respectively.

[0038] The cleaning mechanism 4 includes a support 401, which is fixedly connected to the adjacent surfaces of the two material boxes 3. A slide rod 402 is slidably connected in the support 401, and a spring 403 is sleeved on the slide rod 402. One end of the spring 403 is fixed on the slide rod 402, and the other end of the spring 403 is fixed on the support 401. The rear end of the slide rod 402 penetrates the rear wall of the material discharging shell 2, that is, the slide rod 402 penetrates the rear cover plate 203, so that the material discharging shell 2 will drive the slide rod 402 to do a circular motion. The front end of the slide rod 402 is fixedly connected to the ball head 4 04, when the slide bar 402 moves forward, the spring 403 is compressed and stored, and then the spring 403 releases the elastic force to make the slide bar 402 move backward quickly, and the slide bar 402 drives the ball head 404 to move backward, and the ball head 404 knocks the support 401, and the support 401 vibrates and drives the material box 3 to vibrate, so that the succinic anhydride product in the material box 3 is completely dropped, and the succinic anhydride product is prevented from sticking to the inner wall of the material box 3. In this way, the material box 3 can be prevented from being blocked, and the accuracy of the single feeding amount of the material box 3 can also be improved. In another embodiment, Fig.12 As shown, the support 401 can be replaced with a sleeve 405, and the sleeve 405 is fixedly connected to the adjacent surfaces of the two material boxes 3. The slide rod 402 passes through the sleeve 405 and is slidably connected to the sleeve 405. The spring 403 is arranged in the sleeve 405, and the front end of the spring 403 is fixedly connected to the inner wall of the front end of the sleeve 405. The ball head 404 is located on the front side of the sleeve 405. The ball head 404 hits the sleeve 405 to cause the sleeve 405 to vibrate. The contact area between the sleeve 405 and the material box 3 is larger, so the vibration of the sleeve 405 can be transmitted to the material box 3 in a larger range, thereby improving the vibration effect of the material box 3.

[0039] The rear side of the dispensing tube 102 is provided with an extrusion assembly for moving the slide bar 402 forward, and the extrusion assembly includes a cover shell 103 connected to the rear side of the dispensing tube 102 by screws. A through hole is opened on the rear side of the dispensing tube 102, and the diameter of the through hole is larger than the circular motion radius of the slide bar 402. When the unloading shell 2 rotates, the slide bar 402 will be driven to make a circular motion. The through hole is provided on the rear side of the dispensing tube 102 to prevent the dispensing tube 102 from interfering with the movement of the slide bar 402. The cover shell 103 covers the through hole, and a force storage ring 104 is fixedly connected to the inner wall of the cover shell 103. The rear end of the slide bar 402 can conflict with the force storage ring 104, and a notch is provided at the lower end of the force storage ring 104. The two ends of the force storage ring 104 are located at the notch. The side surfaces are respectively a force storage surface 1041 and a force unloading surface 1042. The force storage surface 1041 is an inclined surface, and the force unloading surface 1042 is perpendicular to the front side surface of the force storage ring 104. During the circular motion of the slide bar 402, the force storage surface 1041 will gradually squeeze the slide bar 402 to move forward. When the slide bar 402 moves to the force unloading surface 1042, the slide bar 402 will rebound quickly backwards under the action of the spring 403, and then repeat the above process. Therefore, whenever the material box 3 containing succinic anhydride product moves to the bottom, the slide bar 402 corresponding to the material box 3 will move to the force unloading surface 1042, so that the ball head 404 will knock the material box 3 to complete the unloading of the material box 3.

[0040] The power mechanism 5 includes a mounting base 501 connected to the rear side of the filling tube 102 by screws, and a feeding motor 502 is fixed to the mounting base 501 by bolts, and the output end of the feeding motor 502 is connected to a synchronous belt assembly 503, and the output end of the synchronous belt assembly 503 is connected to three power shafts 504, and the synchronous belt assembly 503 includes three synchronous wheels, and the synchronous wheels are connected and driven by synchronous belts, and the power shaft 504 is fixed on the synchronous wheels. The three power shafts 504 are respectively fixedly connected to the three feeding shells 2, and the power shaft 504 is rotatably connected to the cover 103. The feeding motor 502 provides power, so that the three feeding shells 2 can rotate synchronously, thereby realizing synchronous feeding. In another embodiment, the synchronous belt assembly 503 can be replaced by a sprocket chain assembly, and the sprocket is fixed on the power shaft 504. The synchronous rotation of multiple sprockets is realized by the chain. By setting the sprocket chain assembly, the service life of the power mechanism 5 can be improved.

[0041] The material balancing mechanism 6 includes a material balancing motor 601 connected to one side of the material balancing tube 101 by screws, and the output end of the material balancing motor 601 is fixedly connected to a rotating shaft 602, and the rotating shaft 602 is connected to the inside of the material balancing tube 101 through a bearing. Two spiral pieces 603 arranged symmetrically on the left and right are fixedly connected to the rotating shaft 602, so that the spiral directions of the two spiral pieces 603 are opposite. When the rotating shaft 602 drives the two spiral pieces 603 to rotate, the spiral pieces 603 push the succinic anhydride product to both sides, so that the three dispensing tubes 102 are all filled with succinic anhydride products. In another embodiment, as Fig.13As shown, the material balancing tube 101 is a square tube, and two conveyor belts 604 symmetrically arranged on the left and right are installed and rotated inside the material balancing tube 101. A plurality of evenly distributed push plates 605 are fixed on the conveyor belts 604. Two material balancing motors 601 are set and fixedly connected to the rear side of the material balancing tube 101. The material balancing motor 601 is used to drive the conveyor belt 604 to rotate. The two conveyor belts 604 are driven to rotate in opposite directions by the two material balancing motors 601, so that the push plates 605 push the succinic anhydride product at the bottom end of the material balancing tube 101 to both sides.

[0042] Working principle: When in use, the succinic anhydride product in the storage barrel 1 falls into the equalizing tube 101, and the equalizing motor 601 drives the rotating shaft 602 and the spiral piece 603 to rotate, so that the succinic anhydride product falls evenly into the three filling tubes 102. The feeding motor 502 provides power, and the synchronous belt assembly 503 transmits the power to the three power shafts 504. The power shaft 504 drives the feeding shell 2 to rotate, so that the feeding shells 2 in the three filling tubes 102 rotate synchronously, and the feeding shell 2 drives the material box 3 to rotate. When the material box 3 rotates to the top, The succinic anhydride product falls into the material box 3, and then when the material box 3 rotates downward again, the succinic anhydride product falls downward, completing the unloading. The three filling tubes 102 unload the materials synchronously to realize the simultaneous filling of three packaging bags. The screw rod 303 is rotated to move the adjustment plate 302 back and forth, and the adjustment plate 302 drives the filling block 301 to move back and forth, changing the relative position of the filling block 301 and the material box 3, thereby changing the capacity of the material box 3 and making the single unloading amount of the material box 3 larger or smaller, so that three packaging bags of different specifications can be packed at the same time.

[0043] During the unloading process, the unloading shell 2 drives the material box 3 to move and at the same time drives the slide bar 402 to make a circular motion. When the slide bar 402 is at the bottom, that is, the rear end of the slide bar 402 is at the notch of the force storage ring 104, the slide bar 402 will contact the force storage surface 1041 as the unloading shell 2 moves. The force storage surface 1041 squeezes the slide bar 402 forward, and the spring 403 compresses and stores force. When the slide bar 402 moves to the force unloading surface 1042, the slide bar 402 is no longer squeezed by the force storage ring 104, and the spring 403 rebounds quickly and drives the slide bar 402 to move backward quickly. The slide bar 402 drives the ball head 404 to move backward quickly, so that the ball head 404 knocks the support 401, and the support 401 vibrates and causes the material box 3 to vibrate, thereby preventing the succinic anhydride product from sticking to the inner wall of the material box 3, which can avoid blockage of the material box 3 and also improve the accuracy of the single unloading amount of the material box 3.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
