Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mixers, in particular to a sealing connection structure of a mixer feed inlet. BACKGROUND

[0002] At present, the mixer needs to seal the top of the mixer by a cover during stirring to prevent artificial leather materials from flying out during stirring. When the mixer is used to stir a mixture that generates gas, the structure in the prior art cannot meet the above requirements. Because the generation of gas will cause the internal gas pressure to increase, if it is not discharged in time, a safety accident will occur. However, during the exhaust process, the sealing of the feed inlet cannot be affected.

[0003] A sealing structure of a mixer is disclosed in the patent with the publication number CN219252478U, and specifically discloses a sealing structure of a mixer, which comprises a mixer feed inlet. The side end of the mixer feed inlet is welded with a connecting plate at the lower part, and the top end of the connecting plate is fixed with an electric turntable. The top end of the electric turntable is welded with a bearing for the rotation of a rotating shaft. The electric turntable can drive the rotation of the rotating shaft. The top end of the rotating shaft is welded with a rotating rod, and the head of the rotating rod is fixed with a rotating plate. The bottom end of the rotating plate is fixedly connected with an electric hydraulic rod A at the extension part, and the bottom end of the cover is welded with a frame. The upper part of the periphery of the mixer feed inlet is fixedly connected with a frame groove seat with a rubber surface layer inside. Compared with the prior art, the patent has the following beneficial effects: artificial leather materials that need to be stirred are added into the mixer through the mixer feed inlet at the top of the mixer for stirring. Then, external power is supplied to the electric turntable, and its switch is turned on. The rotation of the rotating shaft is driven by the electric turntable. The rotating shaft rotates along the bearing inside. The rotating rod is driven to rotate by the rotating shaft. The rotating plate is driven to rotate by the rotating rod. The cover is driven to rotate by the electric hydraulic rod A through the rotating plate. The cover reaches the position directly above the mixer feed inlet by rotating. Then, external power is supplied to the electric hydraulic rod A. The controller of the electric hydraulic rod A controls the extension of the electric hydraulic rod A. The cover is driven to move downward by the electric hydraulic rod A. The frame is driven to move downward by the cover. The frame is inserted into the frame groove seat. The rubber surface layer in the frame groove seat tightly adheres to the frame by the good elasticity of rubber to achieve sealing. Thus, the sealing effect of the cover is greatly improved. Therefore, the sealing of the mixer can be completed without using manpower.

[0018] like Figures 1 to 12 As shown: Example 1

[0019] A sealing connection structure for a mixer feed inlet includes a baffle 1 mounted on the mixer; a feed connector 5 fixedly connected to the baffle 1, with a support ring 9 inside the feed connector 5 and a feed pipe 6 connected to the support ring 9; a sealing mechanism disposed between the baffle 1 and the feed connector 5, the sealing mechanism including a sealing cover plate 2 connected to the feed connector 5, a fixing ring 10 on the outer end face of the feed connector 5, a first spring 7 on the end face of the fixing ring 10, the first spring 7 being disposed between the sealing cover plate 2 and the fixing ring 10; and an adjustment mechanism including an adjustment box 3, a second spring 34 connected to the sealing cover plate 2, an adjustment rod 33 connected to the second spring 34, a bearing mounting groove 32 connected to the adjustment rod 33 via a bearing, a cam 35 connected to the adjustment rod 33, and an adjustment handle 39 connected to the cam 35.

[0020] In this embodiment, the baffle 1 is fixed on the mixer, and the baffle 1 is fixedly connected to the feed connector 5. The baffle 1 and the feed connector 5 can be connected by a star-shaped rod, which makes it easy to fix the feed connector 5 on the baffle 1. A support ring 9 is provided on the inner side of the feed connector 5. The support ring 9 is connected to the feed pipe 6. During the mixing process, the port of the feed pipe 6 is connected to the feed pipe through a flange.

[0021] A sealing mechanism is provided between the baffle 1 and the feed inlet 5. Specifically, the sealing mechanism includes a sealing cover 2, in which a first spring 7 is provided. The first spring 7 is connected to a fixing ring 10 provided on the feed inlet 5. The sealing cover 2 is a movable structure. When the air pressure inside the mixer is high, it pushes the sealing cover 2 to move outward to achieve gas discharge. The gas discharge can be connected to an air purifier for air purification treatment. This design effectively seals materials that do not need to be dispersed.

[0022] For different materials, a gear design is adopted to adjust the pressure bearing capacity of the sealing cover plate 2. Specifically, this is achieved by setting an adjustment mechanism, which includes a second spring 34 connected to the sealing cover plate 2. The second spring 34 is connected to an adjustment rod 33. By moving the adjustment rod 33, the compression of the second spring 34 can be adjusted, thereby realizing the pressure bearing capacity of the sealing cover plate 2. Example 2

[0023] The inner side of the support ring 9 is welded and fixed to the outer side of the feed pipe 6 to support the feed pipe 6, and the inner and outer contact points are fully welded. The outer side of the support ring 9 is welded and fixed to the feed connector 5. The feed connector 5 is a cylindrical structure, and the axis of the support ring 9 is perpendicular to that of the feed connector 5.

[0024] Unlike the embodiments described above, in this embodiment, the support ring 9 is an annular plate structure, with the feed pipe 6 fixedly welded to its inner side. To achieve a better sealing effect, it is fully welded inside and out. The outer side of the support ring 9 is connected to the inner side of the feed connector 5, also fixed by welding, and the axis of the support ring 9 is perpendicular to that of the feed connector 5.

A plug is provided at the end of the sealing rod 11. The plug can be used to block the exhaust pipe 4. When the sealing cover plate 2 can withstand the internal pressure, the plug is in contact with the exhaust pipe 4. When the sealing cover plate 2 is pushed outward, the plug disengages from the inner port of the exhaust pipe 4, realizing exhaust. Example 6

[0031] One end of the second spring 34 is connected to the adjusting rod 33, and the other end contacts the outer side of the sealing cover plate 2 for pressing the sealing cover plate 2.
