Description

Technical Field

[0001] This utility model relates to the field of paper honeycomb panel production technology, and in particular to a forming device for producing paper honeycomb panels. Background Technology

[0002] Curved paper honeycomb panels are widely used in packaging cushioning, furniture interiors, logistics pallets and other fields due to their lightweight, high strength and curved adaptability. By processing flat paper honeycomb panels into specific arc structures, they can meet the assembly and use needs of non-planar scenarios, and are one of the important development directions of paper packaging and structural materials in recent years.

[0003] However, existing curved paper honeycomb panel forming devices have significant shortcomings: most devices are only equipped with forming molds of a single curvature. If products with different curvatures need to be produced, the entire set of molds must be disassembled and replaced, which is cumbersome and time-consuming to switch between. The devices also have poor adaptability and cannot meet the production needs of multiple specifications. Therefore, in view of the above situation, there is an urgent need to develop a forming device for paper honeycomb panels that can accurately and quickly switch between molds of different curvatures by equipping three sets of curved forming punches and dies with one-to-one curvatures, combined with a synchronous flipping mechanism driven by a servo motor, synchronous wheel, and synchronous belt, so as to meet the production needs of various curved paper honeycomb panels. This device would overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a forming device for producing paper honeycomb panels, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A forming apparatus for producing paper honeycomb panels includes a frame, a synchronous flipping mechanism, a pressing mechanism, curved surface forming punches, curved surface forming dies, and a transfer mechanism. The number of curved surface forming punches and dies is three in total. The curvature of the convex surfaces of the three curved surface forming punches is different, and the curvature of the concave surfaces of the three curved surface forming dies is also different. The curvatures of the three curved surface forming punches and dies are identical in a one-to-one correspondence. The synchronous flipping mechanism includes a servo motor, a first rotating shaft, a second rotating shaft, a synchronous pulley, a synchronous belt, a first turntable, a second turntable, and a transfer plate. The first and second rotating shafts are rotatably connected to the frame, and the servo motor is fixed to the frame. On the frame, the output shaft of the servo motor is connected to the first rotating shaft via a coupling. Synchronous pulleys are fixed on the first and second rotating shafts respectively, and the two synchronous pulleys are connected by a synchronous belt drive. The front end of the first rotating shaft is fixed to the first turntable, and the front end of the second rotating shaft is fixed to the second turntable. Three adapter plates are evenly distributed in a circle on the first turntable. Three curved surface forming punches are evenly distributed in a circle on the front side of the first turntable. Each curved surface forming punch is elastically connected to the adapter plate through an adapter mechanism. Three curved surface forming dies are evenly distributed in a circle on the second turntable. The pressing mechanism is installed on the top of the frame and faces directly downward.

[0006] Preferably, the second turntable is located directly below the first turntable.

[0007] Preferably, the pressing mechanism includes an electric telescopic rod and a pressure plate. There are two electric telescopic rods, which are fixed to the top of the frame. The telescopic ends of the electric telescopic rods are fixed to the pressure plate.

[0008] Preferably, the adapter mechanism includes: a guide rod, a spring, and a top plate. There are two guide rods that slide through the adapter plate and are connected to it. The bottom of the guide rod is fixed to the curved forming punch, and the top of the guide rod is fixed to the top plate. Each guide rod has a spring installed on its outer side. One end of the spring is fixed to the top plate, and the other end is fixed to the adapter plate.

[0009] Preferably, a PLC controller is fixedly installed on one side of the frame, the PLC controller is equipped with a display screen and operation buttons, and the servo motor and electric telescopic rod are electrically connected to the PLC controller.

[0010] The beneficial effects of this utility model are as follows: When producing curved paper honeycomb panels, the forming device first selects the required curvature of the curved forming punch and the curved forming die according to the needs. The first and second rotating shafts are driven to rotate synchronously by the servo motor. The first and second rotating shafts drive the first and second turntables to rotate synchronously. The first and second turntables drive the three curved forming punches and three curved forming dies to rotate synchronously and switch, so that the required curved forming punches and dies rotate to a vertical position. Then, the flat paper honeycomb panel is placed on the curved forming die. The pressure plate is moved down by the electric telescopic rod and presses onto the top plate. The top plate drives the guide rod and the curved forming punch to move down. The curved forming punch presses the paper honeycomb panel into the curved forming die for forming. In summary, this utility model, by equipping three sets of surface forming punches and dies with one-to-one curvature, combined with a synchronous flipping mechanism driven by a servo motor, synchronous wheel, and synchronous belt, can accurately and quickly switch between dies with different curvatures to meet the production needs of various curved paper honeycomb panels.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples are given below.

[0020] See Figures 1-6 In this embodiment of the present invention, a forming device for producing paper honeycomb panels includes a frame 1, a synchronous flipping mechanism 2, a pressing mechanism 3, a curved surface forming punch 4, a curved surface forming die 5, and a transfer mechanism 6. There are three curved surface forming punches 4 and three curved surface forming dies 5. The curvature of the convex surfaces of the three curved surface forming punches 4 is different, and the curvature of the concave surfaces of the three curved surface forming dies 5 is different. The curvatures of the three curved surface forming punches 4 and the three curved surface forming dies 5 are one-to-one corresponding and identical, so that the three curved surface forming punches 4 and the three curved surface forming dies 5 are divided into three different groups for producing paper honeycomb panels with different curvatures.

[0021] The pressing mechanism 3 is installed on the top of the frame 1 and faces directly downward. The pressing mechanism 3 is used to press the curved forming punch 4 directly below it downward.

The telescopic end of the electric telescopic rod 301 is fixed to the pressure plate 302. In use, the electric telescopic rod 301 drives the pressure plate 302 to move downward, and the downward movement of the pressure plate 302 extrudes the curved forming punch 4.

[0022] The synchronous flipping mechanism 2 includes: a servo motor 201, a first rotating shaft 202, a second rotating shaft 203, a synchronous pulley 204, a synchronous belt 205, a first turntable 206, a second turntable 207, and an adapter plate 208. The first rotating shaft 202 and the second rotating shaft 203 are rotatably connected to the frame 1. The servo motor 201 is fixed to the frame 1. The output shaft of the servo motor 201 is connected to the first rotating shaft 202 via a coupling. The first rotating shaft 202 and the second rotating shaft 203... Synchronous pulleys 204 are fixed on each of the two shafts 202 and 203, which are connected by a synchronous belt 205. The front end of the first shaft 202 is fixed to the first turntable 206, and the front end of the second shaft 203 is fixed to the second turntable 207. The second turntable 207 is located directly below the first turntable 206. Three adapter plates 208 are evenly distributed in a circle on the first turntable 206. Three curved forming punches 4 are evenly distributed in a circle on the front side of the first turntable 206. The curved surface forming punches 4 are all elastically connected to the adapter plate 208 through an adapter mechanism 6. The three curved surface forming dies 5 are evenly distributed in a circle and fixed on the second turntable 207. At this time, the curved surface forming punches 4 and curved surface forming dies 5 in the vertical state have the same curvature. The output shaft of the servo motor 201 rotates 120° each time to accurately switch the curved surface forming punches 4 and curved surface forming dies 5. In use, the curved surface forming punches 4 and curved surface forming dies 5 with the required curvature are selected as needed. The servo motor 201 drives the first rotating shaft 202 and the second rotating shaft 203 to rotate synchronously. The first rotating shaft 202 and the second rotating shaft 203 drive the first turntable 206 and the second turntable 207 to rotate synchronously. The first turntable 206 and the second turntable 207 drive the three curved surface forming punches 4 and the three curved surface forming dies 5 to rotate synchronously and switch, so that the required curved surface forming punches 4 and curved surface forming dies 5 can be rotated to the vertical state.

[0023] The adapter mechanism 6 includes: guide rods 601, springs 602 and top plate 603. There are two guide rods 601, which pass through the adapter plate 208 and are slidably connected to it. The bottom of the guide rods 601 is fixed to the curved forming punch 4 and the top is fixed to the top plate 603. Each guide rod 601 has a spring 602 installed on its outer side. One end of the spring 602 is fixed to the top plate 603 and the other end is fixed to the adapter plate 208.

[0024] A PLC controller 7 is fixedly installed on one side of the frame 1. The PLC controller 7 is equipped with a display screen and operation buttons. The servo motor 201 and the electric telescopic rod 301 are electrically connected to the PLC controller 7, and are electrically controlled through the PLC controller 7.

[0025] Working principle: This forming device for producing paper honeycomb panels first selects the curved forming punch 4 and curved forming die 5 with the required curvature when generating curved paper honeycomb panels. The servo motor 201 drives the first rotating shaft 202 and the second rotating shaft 203 to rotate synchronously. The first rotating shaft 202 and the second rotating shaft 203 then drive the first turntable 206 and the second turntable 207 to rotate synchronously. The first turntable 206 and the second turntable 207 then drive the three curved forming punches 4... The three curved surface forming dies 5 rotate synchronously and switch, so that the required curved surface forming punch 4 and curved surface forming die 5 rotate to a vertical position. Then, the flat paper honeycomb board is placed on the curved surface forming die 5. The electric telescopic rod 301 drives the pressure plate 302 to move down and press the pressure plate 302 onto the top plate 603. The top plate 603 drives the guide rod 601 and the curved surface forming punch 4 to move down. The curved surface forming punch 4 presses the paper honeycomb board into the curved surface forming die 5 to form the honeycomb board.
