DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and examples, but these specific implementation schemes do not limit the protection scope of the present invention in any way.

[0025] Example 1

[0026] like Figure 1-2 As shown, a conveyor belt machine for loosening and conveying honeycomb interlayers comprises a frame 1 and a tray 2, the frame 1 is provided with an active roller 3, a conveyor belt 4 arranged on one side of the active roller 3 and a passive roller 5 arranged on the other side of the active roller 3, and a loosening device 6 for loosening the honeycomb interlayer 15 is also arranged between the active roller 3 and the passive roller 5.

[0027] In this embodiment, the loosening device 6 includes fixed frames 7 on both sides, rollers 8 connecting the fixed frames 7 on both sides, and comb teeth 9 obliquely arranged on the rollers 8.

[0028] The loosening device 6 is provided with a height adjustment device 10 for adjusting the height of the comb teeth 9 and a rotation angle adjustment device 11 for adjusting the rotation of the roller 8 to change the angle of the comb teeth 9. The height adjustment device 10 includes a screw nut assembly arranged on the top of the fixed frame 7, the upper end of the screw is connected to the top knob, and the lower end is threadedly connected to the fixed frame 7. The roller 8 and the comb teeth 9 are connected to the screw nut through the bracket. When the top knob is rotated, the screw rotates, driving the screw nut to move up and down, thereby driving the comb teeth 9 to rise and fall to achieve height adjustment. The rotation angle adjustment device 11 includes a worm gear mechanism arranged on the side of the fixed frame 7, one end of the worm is connected to the side knob, and the other end is connected to the bearing of the fixed frame 7. The worm wheel is coaxially fixedly connected to the roller 8. When the side knob is rotated, the worm rotates, driving the worm wheel to rotate, thereby driving the roller 8 to rotate a certain angle to change the inclination angle of the comb teeth 9 (the screw nut assembly belongs to the conventional technology in this field and is arranged inside the structure, so it is not illustrated with a figure).

[0029] The comb teeth 9 are composed of a plurality of steel tines, which are arranged in parallel at equal intervals to form a comb-like structure. Each tine is conical, with a pointed top and a tip angle of 30°-60°, preferably 45°. The length of the tines is 20-50 mm, the diameter is 2-5 mm, and the spacing is 10-20 mm. The specific size can be optimized and designed according to the aperture and density of the honeycomb sandwich 15.

[0030] The sharp teeth are connected as a whole through the bottom plate, which is a rectangular steel plate with a width equal to the length of the roller 8. The bottom plate is connected to the lead screw nut through a bracket, which is an L-shaped steel plate, one end of which is welded to the bottom plate and the other end is hinged to the lead screw nut through bolts.

[0031] When the honeycomb interlayer 15 passes through the comb teeth 9 driven by the roller 8, some of the sharp teeth are inserted into the honeycomb holes, which have the effect of expanding and unblocking the honeycomb wall. Since the sharp teeth are conical and have small tips, they will not cause excessive radial force on the honeycomb wall when inserted into the honeycomb holes, thus avoiding damage to the honeycomb structure. At the same time, the sharp teeth are densely arranged, which can effectively unblock each hole of the honeycomb interlayer 15 and ensure the loosening effect.

[0032] The comb teeth 9 and the roller 8 form a certain angle, so that the honeycomb interlayer 15 is subjected to an upward force when passing through, which helps the honeycomb interlayer 15 to separate from the surface of the roller 8 and reduce the conveying resistance. The height and angle of the comb teeth 9 can be adjusted by the height adjustment device 10 and the angle adjustment device to adapt to honeycomb interlayers 15 of different sizes and shapes.

[0033] In this embodiment, the comb teeth 9 of the aerating device 6 can produce the following beneficial effects:

[0034] (1) Thorough loosening: The sharp teeth can penetrate deep into the honeycomb holes and loosen the honeycomb wall in all directions, ensuring that every hole in the honeycomb interlayer 15 is effectively dredged, thereby improving the air permeability and resilience of the honeycomb paper core.

[0035] (2) Less damage: The conical pointed teeth are designed with a small tip, which exerts little radial pressure on the honeycomb wall when inserted into the honeycomb hole, thus reducing damage to the honeycomb structure and ensuring product quality.

[0036] (3) Strong adaptability: Through the height adjustment device 10 and the angle adjustment device, the height and angle of the comb teeth 9 can be flexibly adjusted to adapt to honeycomb interlayers 15 of different specifications, thereby improving the versatility of the equipment.

[0037] (4) Small conveying resistance: The comb teeth 9 are set at an angle with the roller 8, so that the honeycomb interlayer 15 is subjected to an upward force, which helps the honeycomb interlayer 15 to separate from the surface of the roller 8, reduces the friction resistance during the conveying process, and improves the conveying efficiency.

[0038] In this embodiment, the rack 1 is a rectangular frame structure, consisting of four columns 12 and a crossbeam. The bottom of the column 12 is provided with a height-adjustable support foot 13 for maintaining the horizontal stability of the rack 1.

[0039] In this embodiment, the active roller 3 is cylindrical, and both ends are connected to the frame 1 by bearings, and one end of the active roller 3 is connected to a reduction motor 14. The active roller 3 pushes the honeycomb interlayer 15 forward by rotating.

[0040] In this embodiment, the passive roller 5 has a similar structure to the active roller 3, but has no power output. Both ends of the passive roller 5 are clamped on the frame 1. When the active roller 3 pulls the honeycomb interlayer 15, the passive roller 5 changes the movement direction of the honeycomb interlayer 15 from vertical to horizontal transportation.

[0041] A conveyor belt 4 is provided on one side of the active roller 3 in the forward direction of the honeycomb interlayer 15. The conveyor belt 4 is ring-shaped and wound around a plurality of rotating drums on the frame 1 to form a complete conveying mechanism. The conveyor belt 4 is controlled by an externally connected PLC controller to rotate and convey the honeycomb interlayer 15 forward.

[0042] In addition to the above mechanism, the tray 2 is located below the frame 1, and four guide wheels are installed at the bottom of the tray 2 to facilitate the placement and movement of the honeycomb paper core processed in the previous process to the conveyor belt machine for loosening.

[0043] The conveyor belt machine for loosening and conveying the honeycomb sandwich 15 has the following working principle and method:

[0044] In the first step, the honeycomb sandwich 15 processed in the previous step is placed on the tray 2. Four guide wheels are installed at the bottom of the tray 2 to facilitate moving the honeycomb sandwich 15 to the conveyor belt machine.

[0045] In the second step, the conveyor belt is started, and the active roller 3 starts to rotate through the reduction motor 14. The honeycomb interlayer 15 is pushed by the tray 2 and first passes through the passive roller 5. The passive roller 5 has no power output and changes its movement direction under the push of the honeycomb interlayer 15, changing the movement direction of the honeycomb interlayer 15 from horizontal to vertical.

[0046] In the third step, after the honeycomb interlayer 15 leaves the passive roller 5, it enters the loosening device 6. Driven by the roller 8, the honeycomb interlayer 15 passes through the inclined comb teeth 9. Some of the sharp teeth are inserted into the honeycomb holes, which have the effect of opening and unblocking the honeycomb wall. Since the sharp teeth are conical and the tips are small, they will not cause excessive radial force on the honeycomb wall, avoiding damage to the honeycomb structure. At the same time, the densely arranged sharp teeth can effectively unblock each hole of the honeycomb interlayer 15 to ensure the loosening effect.

[0047] In the fourth step, the comb teeth 9 and the roller 8 form a certain angle, so that the honeycomb interlayer 15 is subjected to an upward force when passing through, which helps the honeycomb interlayer 15 to separate from the surface of the roller 8 and reduce the conveying resistance.

[0048] In the fifth step, the loosened honeycomb interlayer 15 continues to move upward to reach the active roller 3. The active roller 3 pushes the honeycomb interlayer 15 forward by rotating, so that it enters the conveyor belt 4 located on one side of the active roller 3.

[0049] In the sixth step, the conveyor belt 4 is annular and wound around a plurality of rotating drums on the frame 1 to form a complete conveying mechanism. Under the control of the PLC controller, the conveyor belt 4 rotates to convey the honeycomb sandwich 15 forward to the next process.

[0050] Finally, according to the different specifications of the honeycomb interlayer 15, the height and angle of the comb teeth 9 can be flexibly adjusted by adjusting the height adjustment device 10 and the angle adjustment device of the loosening device 6 to adapt to the honeycomb interlayer 15 of different sizes and shapes, thereby improving the versatility of the equipment.

[0051] It is emphasized again that the frame 1 of the entire conveyor belt machine adopts a rectangular frame structure, which is composed of four columns 12 and a crossbeam. The bottom of the column 12 is provided with a height-adjustable support foot 13 to maintain the horizontal stability of the frame 1. The crossbeam is provided with a through hole for installing the active roller 3 to ensure the stable operation of the active roller 3.

[0052] The beneficial effects that can be produced by the conveyor belt machine for loosening and conveying the honeycomb interlayer in the above-mentioned embodiment include the following points: 1. The loosening device of the utility model adopts a comb tooth structure design, and the comb teeth can penetrate into the honeycomb holes to loosen the honeycomb wall in all directions, ensuring that each hole is effectively unblocked, thereby improving the air permeability and resilience of the honeycomb paper core, and solving the problem of easy deformation and collapse of the honeycomb interlayer in the background technology.

[0053] 2. In the utility model, the comb teeth are designed with conical pointed teeth with fine tips. When inserted into the honeycomb holes, the radial pressure on the honeycomb wall is small, which reduces the damage to the honeycomb structure, improves the product quality, and overcomes the defects of the prior art that the loosening effect is poor and the honeycomb structure is easily damaged.

[0054] 3. The utility model is also provided with a height adjustment device and an angle adjustment device, which can flexibly adjust the height and angle of the comb teeth to adapt to honeycomb interlayers of different sizes and shapes, thereby improving the versatility and adaptability of the equipment and solving the problem of poor versatility of existing equipment in the background technology.

[0055] 4. In the utility model, the comb teeth and the roller are arranged at a certain angle, so that the honeycomb interlayer is subjected to an upward force component when passing through, which helps it to separate from the roller surface, reduces the friction resistance during the conveying process, improves the conveying efficiency, and overcomes the defects of large conveying resistance and low efficiency of the honeycomb interlayer in the background technology.

[0056] The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of protection of the present invention. Any innovative improvement or replacement based on the present invention shall fall within the scope of the claims of the present invention. At the same time, the various parameters, materials, and processes mentioned in the above embodiments are not exclusive. Without departing from the technical essence of the present invention, a person of ordinary skill in the art may make various alternatives, and these alternatives shall also be deemed to fall within the scope of protection of the present invention.
