Description

Technical Field

[0001] The utility model relates to the technical field of metal powder mixing and granulating machinery, in particular to a conveying pipe corrector for an internal mixer. Background Art

[0002] A mixing granulator, also known as an internal mixer, is a device used to heat and stir rubber / polymer materials and metal powders for granulation. When the materials are stirred, the inside of the mixing chamber needs to be heated at high temperature so that the materials are melted and mixed, and then transported to the granulator through the conveying screw for granulation. During the conveying process, the conveying barrel (material pipe) needs to be heated to prevent the material from solidifying.

[0003] However, since the existing conveying barrel (material pipe) is connected to the silo, the working temperature in the mixing silo is higher than that of the conveying barrel (material pipe), which makes the temperature of part of the conveying barrel (material pipe) relatively low, resulting in a temperature difference at the position where the conveying barrel is connected to the granulator, causing uneven heating of the conveying barrel, which causes one end of the conveying barrel to deform and warp. Since the conveying screw runs inside the conveying barrel, it is easy for the conveying screw to collide with the inner wall of the conveying barrel, causing noise and equipment failure.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a conveying pipe corrector for an internal mixer, which has a body, and a mixing chamber and a granulator are respectively installed on the body. The utility model is characterized in that the mixing chamber and the granulator are connected through a heating barrel assembly, a conveying screw is arranged in the heating barrel assembly, and a deformation correction device is arranged around the outside of the heating barrel assembly so that the deformation correction device applies pressure to the heating barrel assembly, and the deformation correction device is fixed on the body.

[0006] In the above-mentioned internal mixer conveying pipe corrector, the deformation correction device includes a mounting seat fixed on the machine body, a receiving cavity is provided in the mounting seat, the heating barrel assembly is inserted into the receiving cavity, and at least four side surfaces of the mounting seat are provided with pressure regulating parts, and the pressure regulating part can be extended and retracted toward the receiving cavity.

[0007] In the above-mentioned internal mixer conveying pipe corrector, the pressure regulating part includes a nut fixed on a mounting seat, an adjusting screw is threadedly installed in the nut, the adjusting screw passes through the mounting seat, a nut is provided at one end of the adjusting screw, and a pressure block is provided at the other end, the pressure block is located in the accommodating cavity, and the pressure block corresponds to the heating barrel assembly.

[0008] In the above-mentioned internal mixer conveying pipe straightener, the heating barrel assembly includes an inner barrel, the outer wall of the inner barrel is sleeved with a heating ring, the conveying screw is inserted into the inner barrel, one end of the inner barrel is provided with a connecting flange to fix the inner barrel on the granulator, and the other end is connected to the mixing chamber.

[0009] In the above-mentioned internal mixer conveying pipe straightener, at least two heating rings are provided, a gap is provided between at least two of the heating rings, and the pressing block corresponds to the gap.

[0010] The beneficial effect of the utility model is that when the surface of one end of the heating barrel assembly close to the granulator is deformed and warped due to uneven heating, pressure can be applied to the warped position of the surface of the heating barrel assembly through the deformation correction device to correct the deformed position, thereby preventing the heating barrel assembly from deforming and causing the inner wall to collide with the conveying screw to cause friction noise and damage, thereby reducing the failure rate of the equipment.

[0016] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0017] Combination Figures 1 to 4 The shown embodiment is a conveying pipe corrector for an internal mixer, which comprises a body 1, on which a mixing chamber 2 and a granulator 3 are respectively mounted, and is characterized in that the mixing chamber 2 and the granulator 3 are connected via a heating barrel assembly 4, a conveying screw is arranged in the heating barrel assembly 4, and a deformation correction device 5 is arranged around the outer side of the heating barrel assembly 4 so that the deformation correction device 5 applies pressure to the heating barrel assembly 4, and the deformation correction device 5 is fixed on the body 1; in this embodiment, when the surface of the heating barrel assembly 4 is deformed and warped due to uneven heating, the deformation correction device 5 can apply reverse pressure to the warped position of the surface of the heating barrel assembly 4, so that the deformed position is corrected, thereby preventing the heating barrel assembly 4 from causing friction noise and damage due to collision between the inner wall and the conveying screw due to deformation, thereby reducing the failure rate of the equipment.

[0018] Combination Figure 2 and Figure 3 As shown, the deformation correction device 5 of this embodiment includes a mounting base 6 fixed on the body 1, a receiving cavity is arranged in the mounting base 6, the heating barrel assembly 4 is inserted in the receiving cavity, and at least four side surfaces of the mounting base 6 are provided with pressure regulating parts, and the pressure regulating parts can be extended and retracted toward the receiving cavity, that is, the pressure regulating parts are respectively located at the upper, lower, left and right positions of the mounting base 6 to better cover the outer position of the heating barrel assembly 4; so that the pressure regulating part can be extended and retracted on the outer side of the heating barrel assembly 4, thereby pressing against the surface of the heating barrel assembly 4 for correction.

[0019] Among them, the pressure regulating part of this embodiment includes a nut 7 fixed on the mounting seat 6, an adjusting screw 8 is installed in the nut 7 through a thread, the adjusting screw 8 passes through the mounting seat 6, a nut is provided at one end of the adjusting screw 8, and a pressure block 9 is provided at the other end. The pressure block 9 is located in the accommodating cavity, and the pressure block 9 corresponds to the heating barrel assembly 4; by rotating the nut, the adjusting screw 8 rotates on the nut 7, so that the pressure block 9 is expanded and contracted in the accommodating cavity, so that the pressure block 9 is pressed toward the deformed position, so that the deformed position is corrected to prevent the heating barrel assembly 4 from being deformed and tilted due to uneven heating.

[0020] It is worth noting that in some embodiments, the pressing block 9 can adopt a shape that matches the outer wall of the heating barrel assembly 4, such as an arc-shaped pressing block, so that the pressing block 9 can better fit the surface of the heating barrel assembly 4 for correction.

[0021] In some embodiments, the pressing block 9 may not be used, and the correction can be performed by applying reverse pressure to the surface of the heating barrel assembly 4 by adjusting the screw 8.

Since the temperature of the material inside the mixing chamber 2 is relatively high, when the material is output to the inner barrel 10, the barrel needs to be heated to different temperature requirements to prevent the material from cooling down too quickly, while ensuring that the granulator can granulate smoothly.

[0023] In the present embodiment, at least two heating coils 12 are provided, and there is a gap between at least two heating coils 12, and the pressing block 9 corresponds to the gap; since there are gaps between the plurality of heating coils 12, the pressing block 9 can be used to correct them to prevent them from being pressed against the heating coil 12 to cause damage.
