Description

Technical Field

[0001] The utility model belongs to the technical field of packaging carton production facility design, in particular to a flattening device for packaging carton production. Background Art

[0002] Carton is a common packaging material, usually made of cardboard, which is a material made of multiple layers of pulp that have been pressed and bonded. Cartons can be designed into various shapes and sizes according to different uses, and are widely used in the transportation, storage and sales packaging of goods. Cartons are light in weight, easy to carry and transport, and will not add too much extra burden. At the same time, they are low in cost: the production cost of cartons is relatively low, which is suitable for large-scale production and use.

[0003] Cartons are made by cutting and folding cardboard. Cardboard is prone to bending due to various factors during processing, so it needs to be flattened for subsequent precise processing. Due to the certain toughness of cardboard, the existing flattening device for packaging carton production is difficult to completely flatten the cardboard after pressing down, and the flattening effect is not good. At the same time, there is a lack of positioning measures during the flattening process of the support plate, and the flattening accuracy is low. Utility Model Content

[0004] The utility model aims to provide a flattening device for producing packaging cartons to solve the problems existing in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A flattening device for producing packaging cartons, comprising a feeding device, a supporting device is arranged in the middle of the feeding device, and a pressing device is arranged on the top of the supporting device; the supporting device comprises a supporting table, two blocking cylinders are symmetrically installed on the top of the supporting table, and blocks are arranged on the inner sides of the blocking cylinders, a supporting rod is fixedly arranged on one side of the supporting table, a rack is fixedly arranged on one side of the supporting rod, and a limiting rail is fixedly arranged on the side of the support rod away from the rack; the pressing device comprises a connecting frame, a gear is rotatably arranged on one side of the connecting frame, a second motor is installed in front of the gear, a pressing box is fixedly arranged on the side of the connecting frame away from the gear, an electric heating pipe is installed in the middle of the pressing box, and a pressing plate is fixedly arranged on the bottom of the pressing box.

[0007] Furthermore: the feeding device includes two front-to-back symmetrical brackets, a transmission shaft is rotatably arranged on the top of the bracket, a first motor is installed at one end of the transmission shaft, and a conveyor belt is arranged between the transmission shafts.

[0008] Furthermore: the transmission shaft is connected to the bracket bearing.

[0009] Furthermore: the cross section of the limit rail is T-shaped, and the connecting frame is slidably connected to the limit rail.

[0010] Furthermore: the gear is key-connected to the second motor.

[0011] Furthermore: the press box is square, and the press box is bolted to the connecting frame.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The connecting frame supports the second motor to drive the gear to rotate, and the meshing rack drives the connecting frame to move downward along the limit rail, driving the pressing box to press down to the top of the cardboard. The cardboard is flattened under the up and down squeezing action of the pressing plate and the support table. At the same time, the pressing box supports the electric heating tube to release heat to heat the heat-conducting liquid. The heat-conducting liquid evenly transfers the heat to the pressing plate, so that the pressing plate is fully heated. The cardboard is baked synchronously during the process of pressing the cardboard. By arranging the pressing box on the top of the pressing plate, the cardboard is heated synchronously during the pressing process, which improves the dryness of the cardboard and prevents it from bending again, so as to enhance the cardboard flattening effect;

[0014] 2. During processing, the bracket supports the first motor to drive the transmission shaft to rotate, driving the conveyor belt to lift the cardboard to be flattened and move forward. When the cardboard is about to move to the bottom of the pressing box, the support table supports two blocking cylinders to pop out blocks. The blocks block the cardboard on the conveyor belt, which is convenient for accurately positioning the cardboard under the pressing box. By setting the design of blocking the cardboard movement by setting the blocking cylinder, the cardboard can be accurately stopped, preventing the cardboard from being displaced due to inertia when the conveyor belt stops moving, affecting the accuracy of flattening, and facilitating further improvement of processing accuracy.
