Description

Technical Field

[0001] This utility model relates to the field of fire door processing technology, specifically a cutting device for processing marine fire doors with a positioning structure. Background Technology

[0002] Marine fire doors are important fire prevention equipment on ships. They are mainly installed in the cabins and walkways of ships and form a heat-resistant and smoke-blocking restrictive interface. In the event of a fire, this can delay and prevent the spread of flames, buying time for personnel to evacuate and for extinguishing the fire. During the production and processing of fire doors, cutting is required. Currently, there are various cutting devices available on the market for processing marine fire doors, but some shortcomings still exist.

[0003] For example, Chinese utility model patent with authorization announcement number CN221210134U discloses a cutting device for processing fire doors. After the water pump is started, it absorbs coolant from the outside and sprays it out from the nozzle through the hose to cool the door panel and the cutting blade. The rotation of the motor drives the reciprocating screw to rotate through the transmission belt. The rotation of the reciprocating screw causes the slider to drive the nozzle to move up and down, thereby further improving the cooling effect.

[0004] The existing technology has the following technical problems: the inability to position the fire door during the processing and cutting process leads to positional movement during cutting, which affects the cutting accuracy. At the same time, the cutting process generates waste chips, which can scatter and pose safety risks to the operators. Therefore, we propose a cutting device for processing marine fire doors with a positioning structure to solve the problems mentioned above. Utility Model Content

The current cutting device for processing marine fireproof doors, combined with the existing solution and actual production and processing use, cannot be positioned during the processing and cutting of fireproof doors, which will cause the position to move during the cutting process, thus affecting the cutting accuracy. At the same time, waste chips are generated during cutting, and the waste chips will be scattered, which will cause safety problems for the operators.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6 This utility model provides a technical solution:

[0032] To address the problems existing in the prior art, this embodiment provides the following technical solution: a cutting device for processing marine fireproof doors with a positioning structure, comprising a support platform 1; a positioning structure, located on the upper left and right sides of the support platform 1, which can fix the position of the fireproof door, thereby improving the cutting accuracy of the fireproof door; a waste chip absorption mechanism, located on the inner left and right sides of the protective cover 2, which can uniformly absorb and treat the waste chips generated during the cutting of the fireproof door; and an adjustment mechanism, located on the upper side of the cutting blade 11, which can adjust the cutting angle of the cutting blade 11, thereby enabling the fireproof door to be cut from different directions.

[0033] like Figure 2 , Figure 5 and Figure 6As shown, by opening the front door of the protective cover 2 installed above the support platform 1, and then placing the fire door to be cut above the support platform 1, and inside the fixing plates 3 set on the left and right sides above the support platform 1, the motor 10 connected to the outer end of the lead screw 9 set on the left and right sides above the support platform 1 can be opened. At this time, the lead screw 9 will rotate, and the outer side of the lead screw 9 is threadedly connected to the sliding block 7. The lower part of the sliding block 7 is slidably connected to the support frame 8 for limiting, that is, the sliding block 7 can slide on the outside of the lead screw 9. When the sliding block 7 slides outward, it will drive the rotating rod 5 connected on the front and rear sides inside to rotate inward. At this time, the connecting rod 6 connected to the outer side below the rotating rod 5 will also rotate. When the rotating rod 5 rotates inward, it can cause the push rod 4 connected below to move inward. Since the fixing plate 3 is fixedly installed on the inner side of the push rod 4, that is, the fixing plate 3 can move inward, the fire door can be clamped and fixed, thereby improving the accuracy of subsequent fire door cutting.

[0034] like Figure 2 , Figure 3 and Figure 4 As shown, a cutting blade 11 is installed above the center of the protective cover 2. The cutting blade 11 is located at the output end of the electric telescopic rod 15, which can be opened. The output end of the electric telescopic rod 15 can push the cutting blade 11 to move downwards and make contact with the fire door. A gear 13 is fixedly installed above the electric telescopic rod 15, and the front side of the gear 13 is meshed with a rack 14. The right side of the rack 14 is also connected to the electric telescopic rod 15. Furthermore, a bracket 16 is fixedly connected to the outside of the electric telescopic rod 15 for limiting. At the same time, a moving block 17 is rotatably connected above the gear 13. When the electric telescopic rod 15 is opened, the output end of the electric telescopic rod 15 can push the rack 14 to slide inside the bracket 16. At this time, the rack 14 will cause the meshing gear 13 to rotate. When the gear 13 rotates, the electric telescopic rod 15 and the cutting blade 11 installed below will also rotate, which can adjust the cutting angle of the cutting blade 11.

[0035] Additionally, the lead screw 9 is connected to the internal thread of the movable block 17, and a fixed rod is engaged with the internal rear side for limiting the movement. The lead screw 9 is rotated and positioned inside the fixed block 18. When the motor 10 connected to the right end of the lead screw 9 is turned on, the lead screw 9 will rotate. At this time, the movable block 17 will move left and right on the outside of the lead screw 9. Meanwhile, the fixed block 18 is positioned inside the lower part of the electromagnetic slide rail 19. The electromagnetic slide rail 19 can be opened, and the fixed block 18 can move back and forth inside the electromagnetic slide rail 19, allowing the cutting blade 11 to move and adjust in all directions. Then, the cutting blade 11 is turned on to cut the fire door. At the same time, a fan 12 is installed on the right side of the cutting blade 11. After the cutting blade 11 has finished cutting, the fan 12 can be turned on to cool the cutting blade 11.

[0036] The protective cover 2 is installed above the support platform 1 to block the flying debris during the cutting of the fire door. At the same time, the chip suction ports 20 are installed at equal intervals on the left and right sides inside the protective cover 2. The chip suction ports 20 are located inside the fixed frame 21. An electric telescopic rod 15 is installed on the outside of the fixed frame 21. When the electric telescopic rod 15 is opened, it can push the fixed frame 21 to move inward. The chip suction pipe 22 is fixedly connected to the outside of the fixed frame 21. The chip collection box 23 is connected to the rear middle part of the chip suction pipe 22. When the air pump installed on the rear middle part of the chip suction pipe 22 is turned on, the chip suction port 20 will generate suction force to absorb the debris generated during cutting. The debris can enter the fixed frame 21 and the chip suction pipe 22 and finally be transported to the chip collection box 23 for unified collection.

[0037] The working principle of the cutting device for processing marine fire doors with a positioning structure is as follows: by fixing the fire door, it can be ensured that there will be no positional displacement during subsequent cutting. At the same time, the cutting blade 11 can be adjusted in angle, allowing the fire door to be cut from different directions. In addition, the waste generated during cutting can be uniformly absorbed and treated, thereby ensuring the safety of the operators.
