Description

Technical Field

[0001] The utility model relates to the technical field of corrugated cardboard processing, in particular to a hot pressing bonding device for corrugated cardboard. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper sandwich and one layer of cardboard. It has high mechanical strength and can withstand collisions and falls during transportation. During processing, the corrugated cardboard needs to be glued together. The corrugated core paper sandwich in the middle of the corrugated cardboard has the strongest hardness. It is usually made by gluing cardboard on both sides of the corrugated core paper sandwich.

[0003] For example, the utility model patent with application number: 202320045601.9 discloses a corrugated cardboard hot pressing and laminating device, including a base, the upper surface of the base is fixedly connected to a fixed plate, the upper surface of the base is fixedly connected to a fixed block, the right surface of the fixed block is rotatably connected to a threaded rod penetrating its left surface, the right surface of the fixed block is fixedly connected to a sliding rod, a pushing block is provided on the threaded rod, the vertical plate of the pushing block is threadedly sleeved on the outer surface of the threaded rod, and the right end of the sliding rod slides through the right surface of the vertical plate of the pushing block. The corrugated cardboard hot pressing and laminating device avoids the need for workers to spend manpower when removing the corrugated cardboard after hot pressing is completed, and also avoids the high temperature of the processed corrugated cardboard and the possibility of burns from workers touching the corrugated cardboard during the removal process, and avoids the possibility of burns from touching the heating component during the removal process, thereby increasing the safety of the device and eliminating the need for manual material removal, thereby saving manpower.

[0004] The device in the above patent can automatically remove the corrugated cardboard after hot pressing and bonding from the device during actual use, thereby preventing workers from being burned and improving the safety of the device during use. However, when adding the corrugated cardboard to be hot pressed and bonded to the fixed plate, there is still a risk of being burned by the hot pressing mechanism. At the same time, waiting for the corrugated cardboard to be hot pressed and bonded to be completed during the loading process will result in some time being wasted. When a large number of corrugated cardboards are hot pressed and bonded, a lot of time will be wasted, thereby reducing the hot pressing and bonding efficiency of the corrugated cardboard.

A push plate 7 is embedded in the bottom of the inner wall of the placement frame 6, and a push rod 8 is fixedly connected to the bottom of the push plate 7. The bottom of the push rod 8 is movably connected to the placement frame 6, and a hot pressing assembly is arranged on the base 1.

[0031] The buffer assembly includes a connecting plate 11 fixedly connected to the bottom of the base 1, and two dampers 12 are provided on the connecting plate 11. The outer surfaces of the two dampers 12 are respectively provided with a spring 13. The tops of the two dampers 12 are fixedly connected with a buffer plate 14. Through the setting of the buffer assembly, the corrugated cardboard can be buffered during hot pressing and bonding, avoiding the damage of the corrugated cardboard due to the high height of the fall and the large impact force, thereby ensuring the quality of the corrugated cardboard after blanking.

[0032] The hot pressing assembly includes a support frame 15 , which is fixedly connected to the top of the base 1 . A cylinder 16 is fixedly installed on the top of the support frame 15 , and a hot pressing plate 17 is fixedly connected to the output end of the cylinder 16 .

[0033] The clamping assembly includes a slot 18, which runs through the bottom of the inner wall of the placement frame 6. The inside of the slot 18 is slidably connected to a slider 19, which is L-shaped. The side of the slider 19 away from the clamping block 20 is fixedly connected to a multi-stage telescopic rod 23, and the outer surface of the multi-stage telescopic rod 23 is provided with a spring three 24. A clamping block 20 is provided on the slider 19, and a slide groove 21 is provided on one side of the clamping block 20. The slide groove 21 is slidably connected to the slider 19, and the inside of the slide groove 21 is fixedly connected to two springs 22. Through the setting of the clamping assembly, the corrugated cardboard placed inside the placement frame 6 can be clamped and fixed, and at the same time, it can avoid hindering the hot pressing and bonding work of the corrugated cardboard.

[0034] Working principle: When working, first place the corrugated cardboard collection frame under the inclined part of the buffer plate 14, and then manually push the two clamping blocks 20 inside the placement frame 6 according to the size of the corrugated cardboard to be hot-pressed and bonded, so that the two clamping blocks 20 respectively drive the two clamping blocks 20 to slide inside the corresponding slots 18, squeezing the spring three 24 and the multi-stage telescopic rod 23, and then put the corrugated cardboard into the placement frame 6, and when its two sides abut against one side and the back side of the inner wall of the placement frame 6, release the two clamping blocks 20, and under the elastic force of the corresponding spring three 24, the two clamping blocks 20 are reset to abut against the other two sides of the corrugated cardboard inside the placement frame 6, clamping and fixing the corrugated cardboard;

[0035] Then, the conveying mechanism 5 is started by the controller 10 to transport the placement frame 6 and the corrugated cardboard. After the placement frame 6 holding the corrugated cardboard is moved to the bottom of the hot pressing plate 17, the rotation of the conveying mechanism 5 is stopped, and the cylinder 16 is started to drive the hot pressing plate 17 to move downward to perform hot pressing and bonding on the corrugated cardboard. In the process of the hot pressing plate 17 moving downward for hot pressing, it will abut against the top of the two clamping blocks 20, pushing the clamping blocks 20 to move downward. Under the action of the slide 21, it slides on the slider 19 and squeezes the spring 22, so as to prevent the clamping blocks 20 from hindering the hot pressing and bonding of the corrugated cardboard. At the same time, during the hot pressing and bonding process, the corrugated cardboard to be hot pressed can be placed in the subsequent placement frame 6, so that hot pressing and loading can be carried out simultaneously.

[0036] When the corrugated cardboard is hot-pressed and moves to the lower chute 2, the guide block 4 can squeeze the push rod 8, so that it drives the push plate 7 to move upward, and the corrugated cardboard inside the placement frame 6 is ejected, and the corrugated cardboard is automatically unloaded. At the same time, after the corrugated cardboard is ejected, the fallen corrugated cardboard can be buffered under the action of the buffer mechanism, that is, after the fallen corrugated cardboard abuts against the buffer plate 14, the damper 12 and the spring 13 will be squeezed to shrink them, and under the action of the damper 12, the impact force generated by the abutment is absorbed, and then the corrugated cardboard can be guided by the inclined buffer plate 14 to slide into the pre-placed collection box.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
