[0002] Weight management is a very important link in the production process of food and drugs. Products need to be finely weighed before leaving the factory to ensure that the weight of the products meets the standard. Since the weight of each product cannot be exactly the same, in order to ensure the qualification rate, the weight standard is usually set as an interval, and the products with weights within the interval are qualified. During the packaging process of products, multiple small bags are usually combined into large packages before leaving the factory. When multiple small bags are at the larger or smaller values within the weight interval, the large packages composed of these small bags will have a problem of excessive weight difference. If these large package products with excessive weight differences are sold, it will affect the reputation of the enterprise. Therefore, these large packages with unqualified weights need to be reprocessed, which will undoubtedly affect the production efficiency of products and increase the processing cost. Therefore, a device that can distinguish products meeting the weight standard into larger, standard, and smaller ones is needed to screen the small bag materials in partitions, facilitate subsequent distribution into large packages, and reduce the weight error of large packages.

Detailed implementation manners

[0022] For the convenience of those skilled in the art to understand, the following further describes the present utility model in detail with reference to the accompanying drawings and specific embodiments.

[0023] As Figure 1 shown, a dynamically weighable machine capable of partition screening includes a weighing unit 100, a guiding unit 200 arranged at the outlet end of the weighing unit 100, and a partition conveyor unit 300 arranged at the outlet end of the guiding unit 200. The weighing unit 100 includes a weighing conveyor belt 110. A control terminal 120 is arranged on one side of the weighing conveyor belt 110. The guiding unit 200 includes a guiding conveyor belt 210. Side plates 211 are arranged on both sides of the guiding conveyor belt 210. A horizontal displacement mechanism 220 perpendicular to the conveying direction of the guiding conveyor belt 210 is arranged above the side plates 211. The horizontal displacement mechanism 220 is connected with a guiding mechanism 230. The partition conveyor unit 300 includes four partition conveyor belts 310 arranged side by side.

[0024] The weighing unit 100 includes a weighing conveyor belt 110, which is used to weigh materials and at the same time drive the materials forward to achieve dynamic weighing. Baffles 111 are provided on both sides of the weighing conveyor belt 110, and the baffles 111 can prevent the materials from deviating from the weighing conveyor belt 110. A protective cover 112 is provided above the weighing conveyor belt 110, and the protective cover 112 can reduce the influence of external wind and dust entering the conveyor belt on weighing. The protective cover 112 is made of transparent material to facilitate the operator to observe the working state of the weighing conveyor belt 110. The two side plates 211 of the protective cover 112 are respectively fixed on the two baffles 111. A visual recognition device 113 is arranged above the inlet end of the weighing conveyor belt 110. The visual recognition device 113 is installed on a bracket, and the two ends of the bracket are respectively fixed on the two baffles 111. The visual recognition device 113 is a barcode scanner, which is used to identify the barcode information on the material package to facilitate recording the weight information of the materials entering the weighing machine for weighing. A control terminal 120 is provided on one side of the weighing conveyor belt 110. The control terminal 120 is an electrical cabinet, and a display screen 121 is provided above the electrical cabinet for observing the data of the equipment operation and at the same time controlling the equipment.

[0025] The guiding unit 200 includes a guiding conveyor belt 210, which is used to drive the weighed materials to move. Side plates 211 are provided on both sides of the guiding conveyor belt 210, and the side plates 211 can prevent the materials from deviating from the guiding conveyor belt 210. A horizontal displacement mechanism 220 perpendicular to the conveying direction of the guiding conveyor belt 210 is provided above the side plates 211. The horizontal displacement mechanism 220 includes a lead screw 221. The two ends of the lead screw 221 are connected to the two side plates 211 through rotating shafts, so that the lead screw 221 can rotate. One end of the lead screw 221 is connected with a rotation driving mechanism, and the rotation driving mechanism is used to provide the driving force for the lead screw 221 to rotate. A ball nut 222 is arranged on the lead screw 221. The ball nut 222 can cooperate with the slotted groove on the lead screw 221 to achieve axial sliding on the lead screw 221. A nut connecting seat 223 is connected to the connecting side of the ball nut 222, and the ball nut 222 drives the nut connecting seat 223 to move.

[0026] The horizontal displacement mechanism 220 further includes a support rod 224. The support rod 224 is arranged between the two side plates 211 and penetrates through the nut connecting seat 223. When the lead screw 221 rotates, a torque that causes the ball nut 222 to rotate will be generated between the lead screw 221 and the ball nut 222 due to contact and friction. This rotational torque will cause the ball nut 222 to rotate and cannot move normally. Therefore, passing the support rod 224 through the nut connecting seat 223 can rely on the support rod 224 to offset the useless torque and prevent the ball nut 222 from driving the nut connecting seat 223 to rotate unnecessarily, and perform horizontal movement smoothly.

[0027] The guiding mechanism 230 is arranged below the nut connecting seat 223 and moves along with the nut connecting seat 223. The guiding mechanism 230 includes a guiding bin 231. After the material enters the guiding bin 231, the guiding bin 231 can drive the material to move. The guiding bin 231 is connected below the nut connecting seat 223. When the nut connecting seat 223 moves along the lead screw 221, it can drive the guiding bin 231 to move, so that the guiding bin 231 can drive the material to move to a specific lateral position on the guiding conveyor belt 210. Elastic guiding belts 232 are connected to both sides of the inlet end of the guiding bin 231. The two guiding belts 232 are respectively connected to the two side plates 211, and the connection points are fixed. The guiding belts 232 can stretch and contract due to elasticity to create a moving space for the movement of the guiding bin 231. The connection points of the two guiding belts 232 and the two side plates 211 correspond to the inlet end of the guiding conveyor belt 210. The guiding bin 231 is located above the outlet end of the guiding conveyor belt 210. This layout makes the distance between the guiding belts 232 longer, and the angle between the connection points of the guiding belts 232 and the guiding bin 231 is relatively gentle to prevent affecting the forward movement of the material. A "V" shape is formed between the two connection points and the guiding bin 231 to guide the material to smoothly enter the guiding bin 231.

[0028] The partition conveyor unit 300 includes four partition conveyor belts 310 arranged side by side. The inlet ends of the four partition conveyor belts 310 are arranged below the outlet end of the guiding conveyor belt 210. During operation, the guiding bin 231 guides the material to the corresponding position of the partition conveyor belt 310, so that the material can fall into the corresponding partition conveyor belt 310. The four partition conveyor belts 310 respectively correspond to four partitions: standard, overweight, underweight, and unqualified, and are used to convey materials in different partitions. The partition conveyor belt 310 includes a driving transmission shaft and a driven transmission shaft. One end of the driving transmission shaft is connected with a rotation driving mechanism, and the rotation driving mechanism drives the driving rotation shaft to rotate. Four conveyor belt members are connected between the driving transmission shaft and the driven transmission shaft. Partition plates 311 are arranged between the four conveyor belt members. The partition plates 311 are used to prevent the materials in the partition conveyor belt 310 from deviating. The partition conveyor unit 300 realizes four partitions through one driving transmission shaft and one driven rotation shaft, avoiding the cost problem caused by four independent conveyor belts.

[0029] It further includes a first support 01, a second support 02, and a third support 03. The weighing unit 100 is arranged on the first support 01, the guiding unit 200 is arranged on the second support 02, and the partition conveyor unit 300 is arranged on the third support 03.

[0030] Working process: First, the materials enter the weighing unit 100 for weighing, and the barcode scanner scans the barcode on the material package to record the product weight information. After weighing, the materials enter the guiding unit 200, and the guiding unit 200 guides them to the corresponding partition conveyor belt 310 according to the product weight information, completing the partition screening and conveying of the materials.

[0031] The above embodiments are the preferred implementation manners of the present utility model, and are not intended to limit the present utility model. Without departing from the inventive concept of the present utility model, any obvious replacement is within the protection scope of the present utility model.
