Abstract
Description
Technical Field
[0001] This utility model relates to the field of door product manufacturing technology, and in particular to an emergency protection device for honeycomb paper production. Background Technology
[0002] Honeycomb paperboard is made based on the principle of honeycomb structure in nature. It is a new type of environmentally friendly and energy-saving sandwich structure material made by bonding corrugated base paper into countless hollow three-dimensional regular hexagons to form a whole load-bearing component - honeycomb paper core, and then bonding face paper to both sides of it.
[0003] During the production of honeycomb paperboard, the honeycomb paper core needs to be stretched and shaped first. This shaping process involves stretching and drying. Drying takes place inside a drying chamber equipped with a drive chain with grippers. In drying chambers with hot air outlets at the bottom, if the honeycomb paper reaches the outlet but hasn't disengaged from the grippers, it will continue moving with the chain towards the hot air outlet. This can cause the honeycomb paper to come into close contact with the high-temperature hot air, posing a risk of ignition. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an emergency protection device for honeycomb paper production.
[0005] The objective of this utility model is achieved through the following technical solution: An emergency protection device for honeycomb paper production includes a rotating rod rotatably connected to the discharge end of a drying box, a transmission block provided on the rotating rod, and the transmission block being correspondingly arranged with a transmission chain disposed inside the drying box; The first end of the rotating rod is connected to the first end of the protective plate, the second end of the protective plate is connected to the return spring, and the drying box is equipped with a switch corresponding to the second end of the protective plate; When the honeycomb paper enters the drying chamber outlet and has not yet disengaged from the clamp, the honeycomb paper touches the transmission block and drives the rotating rod to rotate. When the rotating rod rotates, it drives the second end of the protective plate to rotate and touch the switch.
[0006] Furthermore, the inner wall of the discharge end of the drying box is provided with a connecting plate, the connecting plate includes a connecting part and a supporting part, the connecting part is perpendicularly connected to the supporting part, the connecting part is detachably connected to the drying box, the supporting part is provided with a round hole, and the rotating rod is rotatably and coaxially arranged in the round hole.
[0007] Furthermore, the connecting part is connected to the drying oven by bolts.
[0008] Furthermore, the connecting part and the supporting part are an integrated structure.
[0009] Furthermore, the first end of the rotating rod extends to the outer wall of the drying chamber, and the first end of the rotating rod is rotatably connected to the outer wall of the drying chamber through a bearing and a bearing seat.
[0010] Furthermore, a cuboid connecting block is connected to the first end of the rotating rod, the axis of the connecting block being offset from the axis of the rotating rod, and the first end of the protective plate being connected to the connecting block.
[0011] Furthermore, the transmission block has a cuboid structure, and the axis of the transmission block is offset from the axis of the rotating rod.
[0012] Furthermore, the switch is a limit switch or a proximity switch.
[0013] The beneficial effects of this utility model are: This invention, by incorporating a transmission block, a rotating rod, and a protective plate, can prevent the honeycomb paper from being ignited by high temperatures near the hot air outlet when it fails to automatically detach from the gripper.

[0015] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0016] See Figures 1-4 This utility model provides a technical solution: Example: like Figures 1-4As shown, an emergency protection device for honeycomb paper production includes a rotating rod 2 rotatably connected to the discharge end (inner wall) of a drying chamber 1. A transmission block 3 is provided on the rotating rod 2. The transmission block 3 has a cuboid structure, and its axis is offset from that of the rotating rod 2. The transmission block 3 is correspondingly positioned with the claws on the transmission chain 4 inside the drying chamber 1. Here, "front" refers to the feed end of the drying chamber 1, and "rear" refers to the discharge end of the drying chamber 1. The claws are in front, and the transmission block 3 is behind.
[0017] like Figure 3 and Figure 4 As shown, the first end of the rotating rod 2 is connected to the first end of the protective plate 5, the second end of the protective plate 5 is connected to the return spring 6, and the drying box 1 is provided with a switch 7 corresponding to the second end of the protective plate 5. The switch 7 is a limit switch 7 or a proximity switch 7.
[0018] When the honeycomb paper enters the outlet of the drying chamber 1 and has not yet disengaged from the clamp, the honeycomb paper touches the transmission block 3 and drives the rotating rod 2 to rotate. When the rotating rod 2 rotates, it drives the second end of the protective plate 5 to rotate and touch the switch 7.
[0019] The inner side wall of the discharge end of the drying box 1 is provided with a connecting plate 8. The connecting plate 8 includes an integrated connecting part and a supporting part. The connecting part is perpendicularly connected to the supporting part. The connecting part is detachably connected to the drying box 1 by bolts. The supporting part is provided with a round hole, and the rotating rod 2 is rotatably and coaxially arranged in the round hole.
[0020] The first end of the rotating rod 2 extends to the outer wall of the drying chamber 1, and the first end of the rotating rod 2 is rotatably connected to the outer wall of the drying chamber 1 through the bearing 9 and the bearing 9 seat.
[0021] The first end of the rotating rod 2 is connected to a cuboid connecting block 10. The axis of the connecting block 10 is offset from the axis of the rotating rod 2. The first end of the protective plate 5 is connected to the connecting block 10.
[0022] Working principle: After the honeycomb paper is stretched, dried and shaped, when the honeycomb paper is output, if there is a situation where the honeycomb paper does not automatically disengage from the gripper, the gripper on the transmission chain 4 will drive the honeycomb paper to rotate downward and touch the transmission block 3, and drive the transmission block 3 to move. The transmission block 3 will drive the rotating rod 2 to rotate, and the protective plate 5 on the rotating rod 2 will move synchronously, so that the second end of the protective plate 5 moves towards the switch 7. When the switch 7 is triggered, the drive motor stops, thus preventing the honeycomb paper from continuing to move with the gripper to the lower side of the transmission chain 4 and reducing the distance to the hot air outlet before being ignited.
[0023] This invention, by incorporating a transmission block, a rotating rod, and a protective plate, can prevent the honeycomb paper from being ignited by high temperatures near the hot air outlet when it fails to automatically detach from the gripper.
[0024] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
