DETAILED DESCRIPTION

[0035] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Please refer to Figure 1-Figure 6 The utility model discloses a gas collecting hood suction device, in which a vulcanizer 6 is installed, including a drain 1, a vulcanization seal 2 and a secondary recovery hood 3. A tire is placed in the vulcanizer 6, and the vulcanizer 6 is sealed by the vulcanization seal 2, so as to complete the cross-linking reaction in the vulcanizer 6. In terms of specific structure, the front end of the drain 1 is located above the vulcanizer 6, and the tail end is connected to the air pump, which is used to discharge the gas released by the vulcanizer 6 to the outside. A primary recovery hood 4 is arranged below the drain 1. And the drain 1 can pass through the secondary recovery hood 3 and remain fixed, so that the secondary recovery hood 3 moves along the drain 1. On the other hand, the vulcanization seal 2 is located below the drain 1 and can be connected to the primary recovery hood 4 to drive the primary recovery hood 4 to move synchronously. In this embodiment, a driving device 7 is provided at the bottom of the vulcanization sealing device 2 and the secondary recovery cover 3. The two driving devices 7 can respectively drive the secondary recovery cover 3 and the vulcanization sealing device 2 to move along the length direction. The vulcanizer 6 completes the vulcanization by connecting the vulcanization sealing device 2. When the vulcanization sealing device 2 is opened, since the primary recovery cover 4 is connected to the vulcanization sealing device 2, the primary recovery cover 4 can move outward along with the vulcanization sealing device 2.

[0037] In some embodiments, Figure 5 The drain device 1 includes a joint 11 and a drainage tube 12. The head end of the drainage tube 12 is connected to the first-level recovery cover 4, and the tail end is provided with a joint 11 connected to the air pump. In this embodiment, the drainage tube 12 is a square tube connected by a foldable corrugated sheet along the folding and telescopic direction. The length and curvature of the drainage tube 12 can be freely adjusted, which reduces the difficulty of equipment installation.

[0038] In some embodiments, Figure 2 The vulcanization sealer 2 includes a stand 21 and a cover 22. The bottom of the stand 21 is slidably arranged on the first guide rail 23, so that the stand 21 can move along the first guide rail 23. A manipulator 5 is also arranged at the end of the first guide rail 23 near the vulcanizer 6. When the secondary recovery cover 3 leaves the vulcanizer 6, the manipulator 5 takes out the tire in the vulcanizer 6. On this basis, the cover 22 is movably arranged in the stand 21. A lifting cylinder 24 is arranged at the bottom of the cover 22. The lifting cylinder 24 drives the cover 22 to move up and down, so that the cover 22 is covered on the vulcanizer 6 to achieve the effect of sealing and vulcanization.

[0039] In some embodiments, the driving device 7 includes a motor 71, a driving worm 72, a driving worm wheel 73 and a guide wheel 74. The motor 71 is installed at the bottom of the secondary recovery cover 3. The motor 71 is coaxially connected to the driving worm 72, and the driving worm wheel 73 is meshingly connected to the driving worm 72, thereby increasing the output power. In this embodiment, the driving worm wheel 73 is coaxially connected to the guide wheel 74, thereby driving the guide wheel 74 to rotate, and then making the guide wheel 74 roll along the first guide rail 23 or the second guide rail 33, thereby dragging the primary recovery cover 4 and the secondary recovery cover 3 to move freely.

[0040] In this embodiment, if Figure 3 and Figure 4 The secondary recovery cover 3 includes a base frame 31 and a second guide rail 33, wherein a frame 32 is installed on the top of the base frame 31, and a motor 7 is installed on the bottom of the base frame 31. In combination with the previous embodiment, the motor 7 drives the driving worm 72 to rotate by driving the worm gear 73, and the driving worm 72 is meshed and connected with the second guide rail 33 located below the base frame 31, so that the secondary recovery cover 3 moves along the direction of the second guide rail 33. In addition, a plurality of rollers cooperating with the first guide rail 23 are provided at the bottom of the base frame 31 to reduce the movement resistance.

[0041] In some embodiments, the primary recovery cover 4 and the secondary recovery cover 3 are both in the shape of a gantry, and are both composed of a number of galvanized square tubes spliced ​​together. In addition, the primary recovery cover 4 and the frame 32 are both provided with a cover. Preferably, the cover is made of flame-retardant silicon-titanium cloth to prevent gas leakage caused by sulfidation reaction.

[0042] The working principle of the equipment is described in detail below. This air hood can work in three stages with the vulcanizer;

[0043] Stage 1: When closing the film, the vulcanization sealer 2, the primary recovery cover 4, and the secondary recovery cover 3 are located at the front end, and the secondary recovery cover 3 is in the innermost layer. At this time, the flow guide 1 collects the exhaust gas;

[0044] In the second stage, in the early stage of mold opening, the vulcanization sealer 2 moves to the rear end, and the primary recovery cover 4 installed thereon moves backward accordingly. At this time, the gas collecting cover formed by the secondary recovery cover 3 is at the front end, and the gas collecting cover formed by the primary recovery cover 4 is at the rear end. The primary recovery cover 4 is extended, and the coverage area is increased, so that the smoke generated by the tire during demoulding continues to be collected in the gas collecting cover;

[0045] In the third stage, at the late stage of mold opening, the vulcanizing sealer 2 moves to the rear end, and the manipulator 5 for grabbing the tire takes the tire out, and then the next tire is vulcanized.

[0046] The time setting of the air valve or air pump is 15 minutes, and the three stages of work can be completed within 15 minutes, which can ensure the smoke collection effect of the drain device 1; and experiments have shown that most of the smoke collection can be completed in about 8 minutes, but this also depends on the position of the drain device 1 and the size of the air volume of the air pump.

[0047] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
