Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery, in particular to a paper box weighing and stacking mechanism. Background Art

[0002] In some industry standards or regulations, in order to ensure the consistency of the quality of cartons, cartons are required to be weighed. The weighing operation can not only detect the consistency of the quality of cartons, but also detect the production defects of cartons, so as to more accurately control the production cost. The weighing operation of cartons is generally the last process in the production process, followed by the stacking and packaging of cartons. However, the existing machines used to process cartons on the market often have only a separate weighing mechanism or a separate stacking mechanism, which cannot form a coherent flow operation, greatly reducing the production efficiency of cartons, and are not suitable for the long-term development of enterprises in the future. Utility Model Content

[0003] The purpose of the utility model is to provide a carton weighing and stacking mechanism, which has weighing and stacking functions, thereby forming a continuous flow operation, greatly improving the production efficiency of the carton, and is suitable for the long-term development of the enterprise in the future.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions: a paper box weighing and stacking mechanism, including: a feed weighing component, which is configured to detect the weight of the product and realize the transmission of the product after the detection is completed; a connecting conveying component, which is configured to receive the product output by the feed weighing component and feed it; a waste rejection component, which is configured to cooperate with the feed weighing component to reject unqualified products on the connecting conveying component; and a stacking box component, which is configured to receive the product output by the connecting conveying component and stack it.

[0005] By adopting the above technical solution, the product is weighed on the feed weighing component and then transmitted to the connecting conveying component. When the product after weighing and testing passes through the rejecting component, the rejecting component is used to reject the unqualified products, and the qualified products are transported to the stacking box component under the action of the connecting conveying component, and the stacking of the products is realized under the action of the stacking box component. The mechanism has the functions of weighing and stacking boxes, thereby forming a coherent flow operation, greatly improving the production efficiency of paper boxes, and is suitable for the long-term development of the enterprise in the future.

[0006] It is further configured that: the feed weighing assembly includes a feed placement area, a weighing placement area arranged on one side of the feed placement area, a weighing module arranged below the weighing placement area, and a feed drive component that drives the products in the feed placement area to enter the weighing placement area and enables the products in the weighing placement area to enter the connecting conveying assembly.

[0007] By adopting the above technical solution, the products are transported into the feeding placement area, and the feeding drive component drives the products in the feeding placement area to enter the weighing placement area to complete the weighing, and enables the products in the weighing placement area to enter the connecting conveying component, thereby realizing the weighing and transmission operation of the products, with a simple structure and low cost.

[0008] It is further configured as follows: the waste rejection component includes a position detection module arranged on one side of the conveying path of the connecting conveying component, a rejection actuator arranged on one side of the conveying path of the connecting conveying component, and a controller connecting the weighing module, the position detection module and the rejection actuator.

[0009] By adopting the above technical solution, the weighing module feeds back the weight of the product to the controller. When unqualified products are transmitted through the position detection module through the connecting conveying component, the position detection module feeds back the position of the unqualified product to the controller, and the controller controls the rejection actuator to execute the rejection operation of the product; while qualified products do not execute the rejection operation.

[0010] It is further configured as follows: a flip block is provided on the line conveying assembly at a position between the feed weighing assembly and the waste rejection assembly, and the flip block abuts against the product transmitted on the line conveying assembly to flip its position.

[0011] By adopting the above technical solution, the product is transmitted through the flip block under the action of the connecting conveying component and the transmission position is flipped under the abutment of the flip block, so that the waste rejection component can perform the product rejection operation more accurately, thereby improving the reliability of the structure.

[0012] It is further configured as follows: the stacking box component includes a base frame, a positioning area formed on the base frame for product input, a stacking area formed above the positioning area and communicated with the positioning area for products to pass through, a lifting component that drives the products in the positioning area to enter the stacking area, an output area formed on one side of the stacking area and communicated with the stacking area for products to pass through, and a pushing component that drives the products in the stacking area to enter the output area.

[0013] By adopting the above technical solution, the product is transmitted into the positioning area under the action of the connecting conveying component to limit the movement of the product, and then the lifting component is used to lift the height of the product so that the product enters the stacking area from the positioning area for stacking. When the specified stacking quantity is reached, the pushing component is set to push the product from the stacking area to the output placement area for stacking, thereby completing the stacking operation of the product.

[0014] It is further configured that: a one-way limiting structure is formed between the positioning area and the stacking area to limit the products from entering the positioning area from the stacking area.

[0015] By adopting the above technical solution, the setting of the one-way limiting structure ensures that the products enter the stacking area normally from the positioning area while limiting the products in the stacking area from entering the positioning area, thereby ensuring the reliability and stability of the structure.

[0016] It is further configured that: a holding component for holding products is provided above the stacking placement area.

[0017] By adopting the above technical solution, the products can be stacked more stably in the stacking area through the provided pressing and holding components, thereby improving the stacking stability.

[0018] It is further configured as follows: the material lifting assembly includes a material lifting push plate arranged below the positioning area and a material lifting driving member driving the material lifting push plate to move; when the material lifting push plate moves, the material lifting push plate restricts the product from entering the positioning area.

[0019] By adopting the above technical solution, the material lifting push plate cooperates with the material lifting driving component to realize the lifting operation of the product.

[0020] It is further configured as follows: the one-way limiting structure includes a one-way rotating block rotatably arranged on the base frame and reciprocatingly rotating between the positioning area and the stacking placement area, and a stop block arranged on one side of the one-way rotating block, the stop block limits the one-way rotating block from rotating toward the positioning area and when the one-way rotating block abuts against the stop block, the product is placed above the one-way rotating block.

[0021] By adopting the above technical solution, the process of the product entering the stacking area from the positioning area pushes the one-way rotating block to rotate upward, so that the product can enter the stacking area normally. The products entering the stacking area are pressed against the top of the one-way rotating block under the action of gravity, thereby achieving stable placement of the products in the stacking area.

[0022] It is further configured as follows: the pressing assembly includes a pressing frame movably arranged on the base frame and a pressing control member for controlling the pressing frame, the pressing frame has a tendency to move toward one side of the stacking area, and the pressing control member limits the movement of the pressing frame toward the stacking area.

[0023] By adopting the above technical solution, the pressing frame is always pressed above the products in the stacking area under the action of gravity. When the products are stacked to a specified height, the pressing control part is used to control the pressing frame to limit its downward movement, so as to ensure that the pushing assembly can stably push the product to move and avoid structural interference.

[0024] In summary, the utility model has the following beneficial effects: the utility model has the functions of weighing and stacking boxes, thereby forming a continuous assembly line operation, greatly improving the production efficiency of paper boxes, and is suitable for the long-term development of the enterprise in the future.
