[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Example 1

[0034] See also Figure 1-5 The utility model provides a technical solution: a honeycomb core continuous stretching machine, comprising:

[0035] A horizontal bonding module 1, which includes a work surface 11, a bonding plate 12 and a flat plate, a honeycomb core strip 91 is placed on the work surface 11, the bonding plate 12 is slidably connected to the work surface 11, the bonding plate 12 is fixedly mounted at the output end of the first driving member 121, the flat plate is fixedly mounted at the output end of the second driving member 15, the flat plate includes a front flat plate 13 and a rear flat plate 14, and the bottom surface height of the front flat plate 13 is less than the bottom surface height of the rear flat plate 14;

[0036] The material storage module 2 comprises a guide inclined surface 21 and a supporting bottom surface 22;

[0037] The friction control module 3 includes a tensile support member 31, on which an arc surface is provided, and the honeycomb core plate 9 passes around the surface of the tensile support member 31;

[0038] The rolling module 4 is used for rolling and pulling the honeycomb core panel 9 forward.

[0039] The first driving member 121 and the second driving member 15 can be specifically driven by a driving cylinder. The first driving member 121 on both sides of the bonding plate 12 is used to drive the bonding plate 12 to slide horizontally, so that the bonding plate 12 squeezes and pushes the honeycomb core strip 91, improves the bonding quality of the honeycomb core strip 91, and then forms a whole. The second driving member 15 is used to control the rise and fall of the flat plate.

[0040] The bottom height of the front flat pressing plate 13 is smaller than the bottom height of the rear flat pressing plate 14, so as to avoid the distance between the front flat pressing plate 13 and the work surface 11 being too small, which would affect the manual bonding and machine pressing of the honeycomb core strips 91. The distance between the rear flat pressing plate 14 and the work surface 11 is fixed, so that the honeycomb core strips 91 can move to the bottom of the rear flat pressing plate 14 to be flattened after pressing, thereby effectively ensuring the stretching effect of the honeycomb core.

[0041] In the production of aluminum honeycomb panels, continuous honeycomb core strips 91 are ensured to enter, and the honeycomb core is continuously stretched, which has high production efficiency and high utilization rate of the honeycomb core strips 91. A honeycomb core cutting device can be added behind the stretching machine to perform fixed-length cutting, thereby providing a honeycomb core panel of a certain length.

[0042] The material storage module 2 arranged between the horizontal bonding module 1 and the friction control module 3, on the one hand, utilizes the guide slope 21 to realize material storage, and on the other hand, utilizes the height difference between the supporting bottom surface 22 and the stretching support member 31 to make the honeycomb core panel 9 subjected to tension in the vertical direction, thereby improving the stretching effect.

[0043] The honeycomb core strip 91 effectively improves the stretching effect of the honeycomb core strip by the combined action of the friction force of the large arc surface on the stretching support member 31, the pulling force of the vertical portion, and the driving force of the driving roller.

[0044] A protruding block 131 is provided at the end of the front flat pressing plate 13, and an avoidance hole corresponding to the protruding block 131 is provided on the bonding pressing plate 12 to ensure that the honeycomb core strip 91 is always controlled in the height direction when the bonding pressing plates are pressed, thereby improving the pressing quality.

[0045] A brush 32 is provided on one side of the stretching support 31, and the brush 32 contacts the honeycomb core panel 9, and the honeycomb core panel 9 passes through the gap between the brush 32 and the stretching support 31. The brush 32 can assist the stretching support 31 in adjusting the friction between the honeycomb core panel 9 and the stretching support 31, thereby effectively improving the stretching effect of the honeycomb core panel 9.

[0046] The two sides of the stretching support 31 are provided with symmetrically arranged brush fixing frames 33, on which screws 331 are provided, and springs 332 are sleeved on the screws 331. The screws 331 pass through the brush 32 and are connected to the horn nuts 333. One end of the spring 332 abuts against the brush fixing frame 33, and the other end of the spring abuts against the brush 32. On the one hand, the brush 32 is elastically connected to avoid the gap between the brush 32 and the stretching support 31 being too small and the honeycomb core plate 9 being unable to pass through; on the other hand, the brush 32 can be flexibly disassembled or installed as a whole according to the stretching requirements.

[0047] The rolling module 4 includes a plurality of driving roller groups, and one driving roller group includes rollers 41 respectively arranged on the upper and lower sides of the honeycomb core plate 9. The rollers 41 are driven by a motor to rotate, and the upper and lower rollers 41 roll and pull the honeycomb core plate 9 forward. When the honeycomb core plate 9 is stretched, multiple driving roller groups can be set as needed, and the stretching effect of the honeycomb core plate 9 can be adjusted by controlling the speed of the rollers 41 of each driving roller group.

[0048] A width detection module 5 is provided on one side of the rolling module 4. The width detection module 5 includes a sensor group symmetrically arranged on both sides of the honeycomb core plate 9. The sensor group includes a plurality of width detection sensors 51 arranged in sequence along the width direction of the honeycomb core plate 9. The plurality of width detection sensors 51 are arranged equidistantly along a straight line. By detecting the difference in the number of sensors of the honeycomb core plate 9, the stretched width of the honeycomb core plate 9 is determined, so that the speed of the driving roller group can be adjusted according to the stretched width, and the stretching effect of the honeycomb core plate 9 can be adjusted.

[0049] Working principle: The stretching machine is mainly composed of four main structural parts: a horizontal bonding module, a material storage module, a friction control module, and a rolling module. The honeycomb core strip 91 performs three main actions at the horizontal bonding module: manual bonding, machine pressing, and machine flattening.

[0050] Artificial bonding: When the honeycomb core strips 91 are stretched, a plurality of honeycomb core strips 91 are first closely arranged on the work surface 11, and two adjacent honeycomb core strips 91 are initially fixed by artificial bonding to form a honeycomb core strip group, and the surface of the honeycomb core strip group facing the rear flat plate 14 is bonded and fixed to the honeycomb core strip group below the rear flat plate 14;

[0051] Machine pressing: Afterwards, the honeycomb core strip group is pushed horizontally by the bonding press plate 12, and the multiple honeycomb core strips 91 in the honeycomb core strip group are firmly bonded;

[0052] Machine flattening: After that, the flattening plate is lifted, and the bonding plate 12 pushes the honeycomb core strip group to move below the rear flattening plate 14, and the flattening plate moves downward, so that the honeycomb core strip group is flattened to ensure the subsequent stretching effect;

[0053] Finally, the honeycomb core strip group under the rear flat plate 14 is stretched by the rolling module 4 to form a honeycomb core panel 9. The honeycomb core panel 9 bypasses the stretching support 31. The stretching support 31 raises the honeycomb core panel 9 to create more friction surfaces with it. The curved surface can prevent the honeycomb core panel 9 from bending.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
