Description

Technical Field

[0001] The utility model relates to the technical field of coating processing, in particular to a stirring barrel covering and sealing device. Background Art

[0002] In the production of paint, the mixing barrels containing raw materials will be transferred between various equipment such as mixers through tracks and work with corresponding equipment at each station. In the mixing process, the slurry is stirred in the barrel by the agitator. Since the process requirements of paint processing are carried out under vacuum conditions after sealing, a capping and sealing device will be used to assist.

[0003] For example, the Chinese utility model patent with patent number 202122779014.6 provides a lid sealing structure for a mixer, which has a sealing rubber on the outside of the sealing plate. The mixing barrel can be sealed by the sealing rubber, and a good fire prevention effect can be achieved by the setting of fireproof cotton. Secondly, it is convenient to take and place the lid.

[0004] However, most of the existing cover sealing structures can only seal mixing barrels of a single size. In the process of paint production, paints with different raw material ratios will be stored in mixing barrels of different sizes. When mixing mixing barrels of different sizes, it is necessary to replace sealing structures of different sizes, which makes it inconvenient to quickly seal mixing barrels of different sizes, reducing the scope of application of the sealing structure.

[0014] In a preferred embodiment, a support frame is provided at the bottom of the frame, and the end of the hydraulic cylinder abuts against the support frame.

[0015] In a preferred embodiment, a sealing ring is provided between the sealing shell and the mounting frame.

[0016] In a preferred embodiment, a connecting cylinder is provided on the output shaft of the vacuum motor, and a connecting shaft is provided on the agitator. The connecting shaft is slidably inserted into the connecting cylinder, a fixing pin is threaded on the connecting cylinder, and a plurality of fixing holes are provided on the connecting shaft, and the fixing pin is inserted into one of the fixing holes.

[0017] In a preferred embodiment, a vacuum pump is provided on the mounting frame, an exhaust end of the vacuum pump is connected to the sealing shell through a pipeline, an electric control valve is provided on the sealing shell, and a through groove connected to the sealing shell is opened on the mounting frame.

[0018] In a preferred embodiment, the sealing block is provided with an adhesively connected fixing plate, and the fixing plate is screwed to the bottom of the mounting frame.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

The supporting slide rail 103 is used to support the mixing barrel, so as to facilitate the transportation of the mixing barrel containing paint between various processing equipments. A lifting device is arranged on the frame 101, and the mixing barrel is driven to rise and fall from the supporting slide rail 103 by the lifting device. The lifting device includes a hydraulic cylinder 201 fixedly arranged at the bottom of the frame 101, and a supporting tray 202 is arranged at the telescopic end of the hydraulic cylinder 201, and the supporting tray 202 can be raised and lowered on the supporting slide rail 103.

[0034] A sealed shell 301 is provided on the mounting frame 104, a vacuum motor 401 is provided inside the sealed shell 301, and a height-adjustable agitator 406 is provided on the output shaft of the vacuum motor 401. The supporting tray 202 can be lifted and lowered by controlling the extension and contraction of the hydraulic cylinder 201. During the lifting and lowering process, the tray can lift the mixing barrel on the supporting slide rail 103, so that the agitator 406 can be located in the mixing barrel, and then the vacuum motor 401 is controlled to start to stir the slurry in the mixing barrel. A supporting bracket 102 is provided at the bottom of the frame 101, and the end of the hydraulic cylinder 201 abuts against the supporting bracket 102. The bottom of the hydraulic cylinder 201 can be supported by the supporting bracket 102 to avoid displacement of the hydraulic cylinder 201 when lifting the mixing barrel, which may cause an accident.

[0035] like Figure 1 , 2 As shown, in this embodiment, multiple groups of sealing blocks 502 are arranged in an annular direction at the bottom of the mounting frame 104, and the outer surfaces of the multiple groups of sealing blocks 502 cooperate to form a round table surface. The sealing blocks 502 can be made of rubber or other flexible materials. When the mixing barrel is lifted, the barrel mouth of the mixing barrel contacts the multiple groups of sealing blocks 502, and then the barrel mouth is sealed by the sealing blocks 502. Moreover, by setting the round table surface, the sealing blocks 502 can match mixing barrels of different calibers, and the sealing effect is better, and there is no need to frequently replace the sealing structure.

[0036] like Figure 2 As shown, in this embodiment, a sealing ring 302 is provided between the sealing shell 301 and the mounting frame 104. The sealing ring 302 can seal the gap between the sealing shell 301 and the mounting frame 104, and after the barrel opening is sealed by the sealing block 502, the cavity between the mixing barrel and the sealing shell 301 is completely isolated from the outside, thereby achieving sealed mixing.

[0037] like Figure 1 , 2 As shown, in this embodiment, a vacuum pump 304 is provided on the mounting frame 104, and the air extraction end of the vacuum pump 304 is connected to the sealed shell 301 through a pipe 305. The sealed shell 301 is provided with an electric control valve 303, and a through slot 105 connected to the sealed shell 301 is provided on the mounting frame 104. When some specific coatings need to be vacuum stirred, the air in the cavity between the stirring barrel and the sealed shell 301 can be extracted by the vacuum pump 304. The through slot 105 is provided to facilitate the air in the stirring barrel to enter the sealed shell 301 and be extracted. After the stirring is completed, the electric control valve 303 can be opened to allow the external gas to enter at a uniform speed, so as to facilitate the unloading of the stirring barrel under normal pressure.

[0038] like Figure 2 , 3As shown, in this embodiment, a fixing plate 501 connected by bonding is provided on the sealing block 502, and the fixing plate 501 is screwed to the bottom of the mounting frame 104. The setting of the fixing plate 501 facilitates the installation of the sealing block 502, and the sealing block 502 with greater wear can be replaced after the fixing plate 501 is disassembled.

[0039] like Figure 2 , 3 As shown, in this embodiment, a connecting cylinder 402 is provided on the output shaft of the vacuum motor 401, and a connecting shaft 403 is provided on the stirrer 406. The connecting shaft 403 is slidably inserted into the connecting cylinder 402, a fixing pin 405 is screwed on the connecting cylinder 402, and a plurality of fixing holes 404 are provided on the connecting shaft 403, and the fixing pin 405 is inserted into one of the fixing holes 404. The height of the stirrer 406 can be adjusted by inserting the fixing pin 405 into the fixing holes 404 at different heights, so that the stirrer 406 can be located at the best stirring position of the stirring barrels at different heights, so as to improve the stirring effect, and further improve the application range of the device.

[0040] Specific usage and beneficial effects of the utility model:

[0041] When the device is in use, the mixing barrel containing the paint is moved to the frame 101 through the supporting slide rail 103, and then the hydraulic cylinder 201 is controlled to extend to drive the supporting plate 202 to rise to lift the mixing barrel, so that the agitator 406 extends into the mixing barrel. During the rising process, the barrel mouth of the mixing barrel contacts the sealing block 502, and since the outer sides of the multiple groups of sealing blocks 502 form a round table surface, the sealing block 502 can match mixing barrels with various barrel mouth sizes to seal their barrel mouths, and the fixing pin 405 can be inserted into the fixing hole 404 at different positions to adjust the height of the agitator 406 to match mixing barrels with different depths so that the agitator 406 can be located at the best stirring position of the mixing barrel for stirring, thereby improving the stirring effect, thereby improving the application range of the device and eliminating the need for frequent replacement of the sealing structure.
