Description

Technical Field

[0001] This utility model relates to the technical field of blade forming machines, specifically a high-sealing smoke exhaust fire damper blade forming machine. Background Technology

[0002] A smoke exhaust fire damper is a fire protection component, usually installed on the duct of a mechanical smoke exhaust system. It is normally open and opens to exhaust smoke in the event of a fire. It closes when the temperature of the smoke in the exhaust duct reaches 280 degrees Celsius and meets the requirements for smoke leakage and fire resistance integrity for a certain period of time, thus playing the role of smoke isolation and fire prevention. The fire damper consists of a valve frame, blades, controller and other structures.

[0003] Chinese patent CN221247745 discloses a fire damper blade forming machine. By pressing buttons on both sides, a push rod is moved to the opposite side. Through the cooperation of a slider and connecting rod, two insert rods are moved to the opposite side, thus disengaging from the slot and allowing for the disassembly and replacement of the blade. The machine has a simple structure and is easy to use, avoiding blade wear caused by prolonged use and improving cutting efficiency. With output belt structures on both sides of the front of the blade, the formed blades can be directly transported to the next process without manual collection, greatly improving the efficiency of blade production.

[0004] In the above solution, when the blade is cut, one end is supported by a support platform, while the other end rests on the conveyor belt structure. Since the conveyor belt is an elastic structure, it is difficult to provide adequate support for the blade, leading to defects such as burrs on the cut surface and affecting the blade's quality. Furthermore, if the conveyor belt structure is in operation during blade cutting, it will cause some displacement to the blade, thus affecting the accuracy of the cut dimensions. Therefore, we provide a high-sealing smoke exhaust fire damper blade forming machine to solve these problems. Utility Model Content

[0029] 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.

[0030] like Figure 1-4 As shown, this utility model provides a technical solution: a high-sealing smoke exhaust fire damper blade forming machine, including a roller press 1, a fixed base 3, a cutting assembly, a moving trough 12 and a belt conveyor 10.

[0031] The discharge end of the roller press 1 is equipped with a feeding plate 2. The roller press 1 is an existing structure that can roll the metal plate entering the roller press 1 to form blades with multiple protrusions, thereby improving the sealing performance of the blades in the fire damper. The feeding plate 2 can support and transport the formed blades.

[0032] The fixed base 3 is fixedly connected to the roller press 1. An adjustment box 4 is installed on the fixed base 3. The bottom surface of the feeding plate 2 abuts against the adjustment box 4. The adjustment box 4 is equipped with a pushing component for pushing the cut blades. The formed blades are transported to the top of the fixed base 3 through the feeding plate 2.

[0033] The pushing component includes a storage slot 17 on the regulating box 4 and a second cylinder 18 installed inside the regulating box 4. A connector is installed on the telescopic end of the second cylinder 18, and a pusher plate 21 is installed on the end of the connector away from the second cylinder 18. The pusher plate 21 is slidably connected to the storage slot 17.

[0034] The extension end of the second cylinder 18 drives the pusher plate 21 to move laterally through the connector, and pushes the pusher plate 21 out of the receiving groove 17, thereby pushing the blade on the fixed seat 3 to one side of the fixed seat 3.

[0035] In this embodiment, the connector includes an adjustment frame 19 and a slide rod 20 slidably connected to the adjustment frame 19. One end of the adjustment frame 19 is fixedly connected to the telescopic end of the second cylinder 18. Two locking nuts 22 are threadedly connected to the slide rod 20, and the locking nuts 22 abut against the adjustment frame 19. The end of the slide rod 20 away from the adjustment frame 19 is fixedly connected to the pusher plate 21.

[0036] In order to adjust the distance between the pusher plate 21 and the telescopic end of the second cylinder 18, the two locking nuts 22 can be rotated, thereby moving the two locking nuts 22 away from each other and adjusting the extension length of the slide rod 20 from the adjustment frame 19. After adjusting to the appropriate position, the slide rod 20 is locked by the two locking nuts 22, thereby adjusting the distance between the pusher plate 21 and the telescopic end of the second cylinder 18.

[0037] Furthermore, a guide rod 23 is fixedly connected inside the adjustment frame 19, and a guide groove 24 is provided on the slide rod 20. The slide rod 20 is slidably connected to the guide rod 23 through the guide groove 24. An inspection door is hinged on the adjustment box 4, and the connection parts can be adjusted by opening the inspection door.

[0038] Both the guide groove 24 and the guide rod 23 are square structures. The slide rod 20 slides on the guide rod 23 through the guide groove 24 to guide the slide rod 20 in the moving state, so that the slide rod 20 will not rotate on the guide rod 23.

[0039] In this embodiment, the movable slot 12 is formed on the fixed base 3, the fixed base 3 is equipped with a motor 13, the output shaft of the motor 13 is equipped with a bidirectional screw 14, and the bidirectional screw 14 is rotatably connected to the movable slot 12. Both ends of the bidirectional screw 14 are threadedly connected to movable seats 15, and both movable seats 15 are equipped with support plates 16.

[0040] The upper surface of the support plate 16 is on the same horizontal plane as the upper surface of the feed plate 2. The output shaft of the motor 13 drives the bidirectional screw 14 to rotate clockwise, and causes the two moving seats 15 to move towards each other, thereby bringing the two support plates 16 closer together. The support plates 16 support the blade in the cutting position. After cutting, the output shaft of the motor 13 rotates counterclockwise, causing the two moving seats 15 to move away from each other, thereby moving the two support plates 16 off the cut blade and dropping the blade above the fixed seat 3.

[0041] The cutting assembly is mounted on the fixed base 3 and is used to cut the blades removed from the feed plate 2. The cutting assembly includes a mounting plate 5, on which two sets of support columns 6 are fixedly connected, and the bottom ends of the support columns 6 are fixedly connected to the fixed base 3. A first cylinder 7 is mounted on the mounting plate 5, and the telescopic end of the first cylinder 7 is fixedly connected to a mounting base 8. A cutter 9 is mounted on the mounting base 8. The cutter 9 is fixed to the mounting base 8 with bolts and can be disassembled and maintained as needed.

[0042] The blade in the cutting state has its bottom ends located on the feed plate 2 and the support plate 16, respectively. The mounting base 8 is driven to move downward by the telescopic end of the first cylinder 7, and the blade is cut by the cutter 9.

[0043] The belt conveyor 10 is located on the side of the fixed base 3 away from the roller press 1. It is used to convey and unload the cut blades. Two symmetrical guide plates 11 are fixedly connected on the fixed base 3, and one end of the guide plate 11 is located above the belt conveyor 10. The cut blades are guided by the guide plate 11 and fall onto the belt conveyor 10. The belt conveyor 10 then transports the blades to the next process.
