Description

Technical Field

[0001] The utility model relates to the technical field of structural adhesive mixing, in particular to a multi-component structural adhesive mixing device. Background Art

[0002] Multi-component structural adhesives are widely used in the construction industry and industrial fields. Multi-component structural adhesives are a high-performance adhesive material, usually composed of two or more separately packaged components. These components need to be mixed in a certain proportion before use to exert their bonding effect.

[0003] During the mixing process of the multi-component structural adhesive mixing device, a stirring mechanism is required for stirring and mixing. After stirring and mixing, a large number of bubbles will appear in the structural adhesive, and these bubbles will cause the overall bonding strength and durability of the structural adhesive to decrease. Utility Model Content

[0004] The utility model aims to provide a multi-component structural adhesive mixing device to solve the problem that a large number of bubbles will appear in the structural adhesive after stirring and mixing, and these bubbles will lead to the reduction of the overall bonding strength and durability of the structural adhesive.

[0005] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a multi-component structural adhesive mixing device, including a mixing barrel, which is rotatably arranged inside a protective shell, a first drive motor is fixed to the middle position of the inner bottom surface of the mixing barrel, a gear is fixed to the output end of the first drive motor, an inner gear ring is fixed to the bottom surface of the protective shell, the gear is meshed with the inside of the inner gear ring, and a sealing cover is arranged on the top surface of the mixing barrel.

[0006] Preferably, a receiving ring is fixed to the upper half of the inner wall of the mixing barrel, a plurality of limit grooves are provided at equal angles on the top surface of the receiving ring, steel balls are rotatably arranged inside the limit grooves, a rotating ring is fixed to the top surface of the protective shell, and the outer bottom surface of the rotating ring is in contact with the plurality of steel balls.

[0007] Preferably, a stirring blade is rotatably arranged inside the mixing barrel, a plurality of guide ports are provided on both sides of the stirring blade, a second drive motor is fixed to the top surface of the sealing cover, an output end of the second drive motor passes through the sealing cover and is fixed to the top end of the stirring blade.

[0008] Preferably, a feed pipe is connected and fixed to the top surface of the sealing cover, a discharge pipe is connected and fixed to the outer wall of the protective shell, and a discharge valve is arranged inside the discharge pipe.

[0009] Preferably, two material transfer rings are fixed on the top surface of the protective shell, and two closing rings are fixed on the top surface of the sealing cover.

[0010] Preferably, two positioning pins are fixed on the bottom surface of the sealing cover, and two positioning grooves are provided on the top surface of the mixing barrel, and the positioning pins are plugged into the positioning grooves.

[0011] Compared with the prior art, a multi-component structural adhesive mixing device using the above technical solution has the following beneficial effects:

[0012] 1. During use, the staff will transfer the structural adhesive to be mixed to the inside of the protective shell. At this time, the staff can start the second drive motor. At this time, the output end of the second drive motor drives the stirring blade to rotate. At this time, the structural adhesive inside the protective shell is stirred by the stirring blade, thereby achieving the effect of mixing the multi-component structural adhesive. When the mixing is completed, the staff starts the first drive motor. The output end of the first drive motor drives the gear to rotate at high speed. At this time, the inner gear ring rotates with the first drive motor through the engagement with the gear, thereby driving the protective shell to rotate at high speed inside the mixing barrel. During the rotation process, the centrifugal force generated by the high-speed rotation causes the bubbles with lighter specific gravity to move to the surface of the structural adhesive and gather. Due to the centrifugal force, the centripetal force they are subjected to is smaller than the structural adhesive itself, thereby achieving the effect of bubble separation. By eliminating the bubbles inside the structural adhesive, the overall bonding strength and durability of the mixed structural adhesive are ensured to be improved; a number of steel balls can reduce the friction of the protective shell during rotation, thereby increasing the rotation speed of the protective shell;

[0013] 2. Before the mixing process of multi-component structural adhesive, the staff will lift the protective shell through the gantry and put it into the mixing barrel. The gantry will be more convenient during the lifting process by adapting the transfer ring to the gantry. At this time, the outer bottom surface of the rotating ring will contact several steel balls. The protective shell will be placed inside the mixing barrel by adapting the receiving ring to the rotating ring. During this process, the staff needs to ensure that the inner gear ring and the gear will mesh together; the staff will connect the glue filling machine with one end of the feed pipe, and then the structural adhesive can be quantitatively transferred to the inside of the protective shell. After multiple groups of structural adhesives are quantitatively transferred to the inside of the protective shell, the staff needs to use the gantry again to lift the sealing cover and place the sealing cover on the top surface of the mixing barrel. During this process, it is necessary to ensure that the positioning pin is inserted into the inside of the positioning groove to facilitate the positioning of the sealing cover and prevent displacement. After the sealing cover and the top surface of the mixing barrel are closed, the stirring blade will be inserted into the interior of the protective shell and will be in contact with the inner wall of the protective shell. When the bubbles are eliminated, the staff can use the gantry to lift the sealing cover and the protective shell. At this time, the staff can discharge the structural adhesive that has been mixed and bubble-eliminated from the interior of the protective shell through the discharge valve inside the discharge pipe.

DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1-Figure 5 As shown, a multi-component structural adhesive mixing device includes a mixing barrel 2, which is a tapered barrel structure that is wide at the top and narrow at the bottom. The mixing barrel 2 is rotatably arranged inside a protective shell 1, a first drive motor 3 is fixed at the middle position of the inner bottom surface of the mixing barrel 2, a gear 4 is fixed at the output end of the first drive motor 3, an inner gear ring 5 is fixed on the bottom surface of the protective shell 1, the gear 4 is meshed with the inner part of the inner gear ring 5, a sealing cover 15 is arranged on the top surface of the mixing barrel 2, a receiving ring 6 is fixed on the upper half of the inner wall of the mixing barrel 2, and the top of the receiving ring 6 A plurality of limit grooves 7 are provided at equal angles on the surface, and steel balls 8 are rotatably arranged inside the limit grooves 7. A rotating ring 9 is fixed to the top surface of the protective shell 1, and the outer bottom surface of the rotating ring 9 is in contact with the plurality of steel balls 8. Lubricating butter is added to the inside of the limit groove 7, and a stirring blade 10 is rotatably arranged inside the mixing barrel 2. A plurality of guide ports 11 are provided on both sides of the stirring blade 10. A second drive motor 12 is fixed to the top surface of the sealing cover 15, and the output end of the second drive motor 12 passes through the sealing cover 15 and is fixed to the top end of the stirring blade 10.

[0022] During use, the staff will transfer the structural adhesive to be mixed to the inside of the protective shell 1. At this time, the staff can start the second drive motor 12. At this time, the output end of the second drive motor 12 drives the stirring blade 10 to rotate. At this time, the structural adhesive inside the protective shell 1 is stirred by the stirring blade 10, so as to achieve the effect of mixing the multi-component structural adhesive. When the mixing is completed, the staff starts the first drive motor 3. The output end of the first drive motor 3 drives the gear 4 to rotate at high speed. At this time, the inner gear ring 5 rotates with the first drive motor 3 by meshing with the gear 4, thereby driving the protective shell 1 to rotate at high speed inside the mixing barrel 2. During the rotation process, through the centrifugal force generated by the high-speed rotation, the bubbles with lighter specific gravity will move to the surface of the structural adhesive and gather. Due to the action of the centrifugal force, the centripetal force they are subjected to is smaller than the structural adhesive itself, so as to achieve the effect of bubble separation. By eliminating the bubbles inside the structural adhesive, the overall bonding strength and durability of the mixed structural adhesive are improved;

[0023] The plurality of steel balls 8 can reduce the friction force of the protective shell 1 during the rotation process, thereby increasing the rotation speed of the protective shell 1 .

[0024] like Figure 1-Figure 3 As shown, the top surface of the sealing cover 15 is connected and fixed with a feed pipe 14, one end of which can be connected to the glue filling machine, the outer wall of the protective shell 1 is connected and fixed with a discharge pipe 13, and a discharge valve is arranged inside the discharge pipe 13, the top surface of the protective shell 1 is fixed with two material transfer rings 16, and the material transfer rings 16 are used for matching with the gantry, the top surface of the sealing cover 15 is fixed with two closed rings 17, and the closed rings 17 are used for matching with the gantry, the bottom surface of the sealing cover 15 is fixed with two positioning pins 18, and the top surface of the mixing barrel 2 is provided with two positioning grooves 19, and the positioning pins 18 are plugged into the positioning grooves 19.

[0025] Before the multi-component structural adhesive mixing process, the staff lifts the protective shell 1 through the gantry and puts it into the mixing barrel 2. The gantry is more convenient in the lifting process by adapting the material transfer ring 16 to the gantry. At this time, the outer bottom surface of the rotating ring 9 will contact with a number of steel balls 8. The protective shell 1 is placed in the mixing barrel 2 by adapting the receiving ring 6 to the rotating ring 9. During this process, the staff needs to ensure that the inner gear ring 5 and the gear 4 are meshed together;

[0026] The staff connects the glue filling machine with one end of the feed pipe 14, and then can transfer the structural glue quantitatively to the inside of the protective shell 1. After multiple groups of structural glue are quantitatively transferred to the inside of the protective shell 1, the staff needs to use the gantry to lift the sealing cover 15 again, and place the sealing cover 15 on the top surface of the mixing barrel 2. During this process, it is necessary to ensure that the positioning pin 18 is inserted into the positioning groove 19 to facilitate the positioning of the sealing cover 15 and prevent deviation. After the sealing cover 15 is closed with the top surface of the mixing barrel 2, the stirring blade 10 will be inserted into the inside of the protective shell 1 and will be in a fit with the inner wall of the protective shell 1;

[0027] When the bubbles are eliminated, the staff can use the gantry to lift the sealing cover 15 and the protective shell 1 away. At this time, the staff can discharge the structural adhesive that has been mixed and bubble-eliminated from the inside of the protective shell 1 through the discharge valve inside the discharge pipe 13.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
