Technical Field

[0001] The utility model relates to the technical field of vulcanizing machine protection, in particular to a safety door protection structure of a full-automatic vacuum rubber vulcanizing machine. Background Art

[0002] The fully automatic vacuum rubber vulcanizer is an advanced rubber processing equipment. The principle of the fully automatic vacuum rubber vulcanizer is to create a negative pressure environment in a closed vulcanization chamber and expose rubber products to a high temperature and low oxygen environment. Under such conditions, the vulcanizer and other additives will react chemically with the rubber, making it strong, wear-resistant and aging-resistant. This vulcanization method can effectively improve the physical properties and chemical stability of rubber products. Because the fully automatic vacuum rubber vulcanizer has the advantages of high degree of automation, precise temperature control and easy operation, the fully automatic vacuum rubber vulcanizer is widely used in the field of rubber processing. However, the safety door of the existing fully automatic vacuum rubber vulcanizer is prone to leakage under long-term negative pressure during use, thereby affecting the use of the equipment. At the same time, the safety door can be opened when the negative pressure inside the vulcanizer is not completely released, which is easy to cause harm to the operator. In view of this, the present utility model is specially proposed. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figure 1-Figure 5 As shown, this embodiment provides a safety door protection structure of a fully automatic vacuum rubber vulcanizer, including a vacuum shell 1, the interior of the vacuum shell 1 is a vacuum chamber of an external rubber vulcanizer, a slide groove 2 is provided on the vacuum shell 1, a safety door body 3 is slidably connected in the slide groove 2, a power component 4 is installed at both ends of one side of the slide groove 2, the power component 4 is connected to the safety door body 3, a limiting hole 5 is provided on the vacuum shell 1, the limiting hole 5 is located on one side of the slide groove 2, and a safety component 6 is provided in the limiting hole 5, and both ends of one side of the safety door body 3 are fixedly installed. A fixing bolt 7 is installed, and a fixing component 8 is installed on one side of the vacuum shell 1. The fixing bolt 7 corresponds to the fixing component 8. When in use, the power component 4 drives the safety door body 3 to move, thereby providing a sealed cavity for the external rubber vulcanizer. The safety door body 3 is then fixed by the fixing component 8. During the rubber vulcanization process, negative pressure will be generated in the cavity, so that the safety door body 3 can be limited by the safety component 6. The safety component 6 will not open when the negative pressure is not completely released, thereby providing a certain degree of protection and reducing the occurrence of accidental opening.

[0021] The sides of the safety door body 3 are provided with sealing strips 9, which are in close contact with the slide 2. The power component 4 includes a self-locking control motor 401, which is fixedly installed on both ends of one side of the slide 2, and a transmission screw 402 is fixedly installed on the output end of the self-locking control motor 401. Threaded holes 10 are provided on both ends of one side of the safety door body 3, and the transmission screw 402 is located in the threaded hole 10, and the transmission screw 402 is threadedly connected to the threaded hole 10. When in use, the self-locking control motor 401 drives the transmission screw 402 to rotate, thereby driving the safety door body 3 to move in the slide 2, and the sealing strip 9 can provide a closed cavity for the external rubber vulcanizer.

[0022] The fixing assembly 8 includes a fixing plate 801, which is fixedly installed on the outside of the vacuum shell 1, and the fixing plate 801 is U-shaped. One end of the fixing bolt 7 is clamped between the fixing plate 801 and the vacuum shell 1. A fixing bolt 802 is provided on one side of the fixing plate 801. The fixing bolt 802 is clamped on the fixing bolt 7, and one end of the fixing bolt 802 is threadedly connected to the vacuum shell 1. When the safety door body 3 moves to one end of the slide groove 2, the fixing bolt 7 is clamped between the fixing plate 801 and the vacuum shell 1, and then the fixing bolt 7 is fixedly clamped between the fixing plate 801 and the vacuum shell 1 by the fixing bolt 802, so that the safety door body 3 can be fixed.

[0023] The safety assembly 6 includes a sliding column 601, which is slidably engaged in the limiting hole 5, and a sealing ring 602 is fixedly installed on the outside of one end of the sliding column 601. The sealing ring 602 is in close contact with the limiting hole 5. A connecting plate 603 is fixedly installed on one end of the sliding column 601. The connecting plate 603 is located on the outer side of the vacuum shell 1. A clamping column 604 is fixedly installed on the other end of the connecting plate 603. A clamping hole 11 is opened on one side of the safety door body 3. The clamping column 604 is clamped in the clamping hole 11. A tension spring 605 is fixedly installed on one end of the sliding column 601. The tension spring 60 5 is fixedly connected to one end of the limiting hole 5. When the external rubber vulcanizer is working, negative pressure will be generated in the cavity, which can drive the sliding column 601 to move in the limiting hole 5, so that the clamping column 604 can be driven to be clamped in the clamping hole 11 through the connecting plate 603, so that the safety door body 3 can be limited, so that the safety door body 3 cannot be opened when the negative pressure is not completely released, thereby improving the safety during use. When the negative pressure is completely released, the tension spring 605 pulls the sliding column 601 to move, so that the clamping column 604 is disengaged from the clamping hole 11, so that the safety door body 3 can be opened.

[0024] When the utility model is in use, the self-locking control motor 401 drives the transmission screw 402 to rotate, thereby driving the safety door body 3 to move in the slide 2, and the sealing strip 9 can provide a closed cavity for the external rubber vulcanizer. When the safety door body 3 moves to one end of the slide 2, the fixing bolt 7 is clamped between the fixing plate 801 and the vacuum shell 1, and then the fixing bolt 802 is used to fix the fixing bolt 7 between the fixing plate 801 and the vacuum shell 1, thereby fixing the safety door body 3. When the vulcanizer is working, negative pressure will be generated in the cavity, which can drive the sliding column 601 to move in the limiting hole 5, so that the clamping column 604 can be driven to clamp in the clamping hole 11 through the connecting plate 603, so that the safety door body 3 can be limited, so that the safety door body 3 cannot be opened when the negative pressure is not completely released, thereby improving the safety during use. When the negative pressure is completely released, the tension spring 605 pulls the sliding column 601 to move, so that the clamping column 604 disengages from the clamping hole 11, so that the safety door body 3 can be opened.
