Description

Technical Field

[0001] The utility model relates to a zinc pyrrolidone carboxylate production device, in particular to a zinc pyrrolidone carboxylate post-processing device. Background Art

[0002] Currently, after zinc pyrrolidone carboxylate powder is produced, it must first be bagged by a powder packaging machine. Each bag is then weighed sequentially to prevent insufficient powder after bagging. After weighing, the bags are packed into cartons using a gripper to ensure a consistent number of bags per carton. After packing, a conveyor platform transports the cartons to a weighing station for further weighing to ensure the required number of bags and total weight meet the requirements. Once qualified, the cartons are then sent to a packaging station for sealing, completing the post-processing of the zinc pyrrolidone carboxylate powder. This entire post-processing process is completed automatically, meeting the manufacturer's automated production requirements.

[0003] However, the drawback of this post-processing device is that, on the one hand, in order to achieve the individual weighing of each powder before packaging, the bags of material need to be weighed in sequence according to a step-by-step conveying method after being sent out by the powder packaging machine, and the conveying platform is in a paused waiting state during the weighing process, so as to ensure that the weighing station only weighs a single bag of material at each weighing. This processing method will cause the bags of material to wait multiple times during the transportation process, reducing the transportation efficiency of the bags of material. On the other hand, in order to ensure the stability of the bagging of the powder and the stability of the bagging of the bag, the post-processing device needs to weigh the bags and cartons separately twice during the processing process, which increases the equipment cost and further reduces its processing efficiency.

[0004] Therefore, the existing post-processing device for zinc pyrrolidonecarboxylate powder has the problem of low working efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a post-processing device for zinc pyrrolidone carboxylate, which can improve the post-processing efficiency of zinc pyrrolidone carboxylate powder.

[0007] The first conveying platform is used to convey the bagged materials to the packing station;

[0008] The push plate assembly is used to push the cartons on the second conveying platform onto the weighing conveying rack in sequence;

[0009] The grabber is used to transfer the bagged materials on the packing station into the cartons on the weighing conveyor rack;

[0010] The weighing conveyor frame is used to record the weight of the carton after each feeding by the gripper, and calculate the individual weight of each bag of material based on the weight difference between the two records. When the individual weight of each bag of material and the total weight of the carton meet the requirements, the weighing conveyor frame will convey the carton to the third conveying platform.

[0011] In the aforementioned post-processing device for zinc pyrrolidone carboxylate, a baffle is provided at one end of the packing station, ribs are provided on both sides of the packing station, and a photoelectric switch for detecting the position of the bag material is provided below the packing station.

[0012] In the aforementioned post-processing device for zinc pyrrolidone carboxylate, the push plate assembly includes a driving shaft and a driven shaft respectively arranged at the front and rear ends of the second conveying platform, both ends of the driving shaft and the driven shaft are rotatably connected to the second conveying platform, and symmetrical conveying chains are provided on both sides of the driving shaft and the driven shaft, and a number of push plates are distributed at intervals on the conveying chains.

[0013] In the aforementioned post-processing device for zinc pyrrolidone carboxylate, the first conveying platform and the second conveying platform are arranged parallel to each other, and the grabber includes a linear slide located above the packing station and the weighing conveyor frame. The linear slide and the first conveying platform are arranged perpendicular to each other, and the slider of the linear slide is connected to a lifting frame, and the lifting frame is connected to a pneumatic suction cup.

[0014] In the aforementioned post-processing device for zinc pyrrolidonecarboxylate, the weighing and conveying frame comprises a base, the base is connected to the conveying frame via a weighing sensor, and the conveying frame is installed with a conveyor belt.

[0016] (1) The present invention cooperates with the second conveying platform, the grabbing arm and the weighing conveying frame to enable the second conveying platform to convey the cartons to the weighing conveying frame, and the grabbing arm sequentially transfers the bags on the packing station to the cartons on the weighing conveying frame for packing. During the packing process, the weighing conveying frame can record the total weight of each carton after the bags are placed, and then calculate the individual weight of each bag, that is, the synchronous measurement of the individual weight of the bag and the total weight of the carton is achieved by a single weighing. And because the measurement process is realized during the packing process of the grabbing arm, it can also use the action interval of the grabbing arm during each feeding to complete the measurement and calculation work, and save the time occupied by the early weighing of the bags and the later weighing of the cartons, effectively improving the processing efficiency of the present invention.

[0017] (2) By optimizing the structure of the push plate assembly, after the cartons are placed on the second conveying platform, the push plates can separate and limit the adjacent cartons from each other, thereby ensuring that the push plate assembly can deliver a single carton to the weighing conveyor rack at a time, ensuring the weighing accuracy of the weighing conveyor rack and the packing stability of the bag material;

[0018] Therefore, the utility model can improve the post-processing efficiency of zinc pyrrolidonecarboxylate powder. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The weighing conveyor frame 2 is used to record the weight of the carton containing bag material after each feeding by the grabber, and calculate the individual weight of each bag material based on the weight difference between the two records. When the individual weight of each bag material and the total weight of the carton meet the requirements, the weighing conveyor frame 2 conveys the carton to the third conveying platform 4.

[0030] The third conveying platform 4 is used to convey the cartons to the packing station for packing.

[0031] An active roller is provided on the first conveying platform 1 at the packing station, a baffle 6 is provided at one end of the packing station, side ribs 7 are provided on both sides of the packing station, and a photoelectric switch 8 for detecting the position of the bag material is provided below the packing station.

[0032] The push plate assembly includes a driving shaft 301 and a driven shaft 302 respectively provided at the front and rear ends of the second conveying platform 3.

[0037] The working principle of the present invention is as follows: During use, the powder packaging machine first bags the powder and places it on the first conveyor platform 1. The first conveyor platform 1 then conveys the bagged material to the boxing station. Once the bagged material is in place, the photoelectric switch 8 detects it and drives the pneumatic suction cup 14 to suck up the bagged material at the boxing station and transfer it to the carton on the weighing conveyor frame 2, completing the boxing function.

[0038] After each bag of material falls into the carton, the overall weight of the carton is detected by the weighing sensor 202 below, and the individual weight of the dropped bag of material is calculated based on the weight difference between the two detected weights, thereby achieving the measurement of the individual weight of the bag of material and the overall weight of the carton, while ensuring the quality of the bagging and boxing of zinc pyrrolidone carboxylate powder, and improving its processing efficiency.

[0039] When the weighing sensor 202 detects that the total weight of the carton reaches the threshold, it means that the number of bags in the carton meets the requirements. Then the conveyor belt 203 drives the carton to the third conveying platform 4, and then the second conveying platform 3 sends the next empty carton to the weighing conveyor frame 2, completing the packing action of the bag materials.
