Description

Technical Field

[0001] This utility model relates to the field of adhesive technology, specifically to a two-component adhesive extrusion tube. Background Technology

[0002] Existing two-component adhesive products (soft / solid type) are all packaged with each component separately. Each component alone is not tacky; only by mixing the two components can the required bonding strength be achieved. Traditional mixing methods involve extruding the two components separately into a mixing container and stirring with a stick. After mixing, the adhesive solidifies upon contact with air. This method makes it difficult to precisely control the amount of adhesive mixed and the ratio between the two components. Furthermore, there are no effective tools to transfer the mixture to the objects to be bonded. After a short time, the adhesive solidifies, leaving residue on the mixing container after use, resulting in waste and difficulty in cleaning. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a two-component adhesive extrusion tube that can mix the two components in equal proportions and output them directly onto the objects to be bonded, without the need for a separate mixing container, thus avoiding adhesive waste, saving time and effort, and being convenient to use.

[0007] The discharge knob switch is rotatably mounted on the pressing chamber, the first air pressure channel and the second air pressure channel. A closing block is provided at the bottom of the discharge knob switch corresponding to the position of the first air outlet and the second air outlet. The discharge knob switch can close or open the first air outlet and the second air outlet by rotating the closing block.

[0008] The sealing cover is placed on the top of the first material cylinder and the second material cylinder. The middle part of the sealing cover is provided with a mounting groove for the discharge knob switch to be installed. The top of the discharge knob switch extends upward from the mounting groove.

[0009] The bottoms of the first and second barrels are respectively connected to the mixing extrusion head through a first and a second glue outlet bending pipe.

[0010] Furthermore, the pressing assembly includes an upper pressing block, a pressing rod, and a piston. The piston is movably located in the pressing chamber, and the pressing rod is movably inserted through the pressing chamber via the discharge knob switch. The bottom end of the pressing rod is connected to the piston, and the top end of the pressing rod is connected to the upper pressing block.

The resulting two-component adhesive is then output through the mixing extruder to the object to be bonded. This invention is convenient to use, saves time and effort, eliminates the need for a separate mixing container, and avoids adhesive waste. Attached Figure Description

[0028] The sealing cover 5 is placed on the top of the first material cylinder 11 and the second material cylinder 12. The middle part of the sealing cover 5 is provided with an installation groove for the discharge knob switch 6 to be installed. The top of the discharge knob switch 6 extends upward from the installation groove.

[0029] The bottoms of the first barrel 11 and the second barrel 12 are respectively connected to the mixing extrusion head 4 through the first glue outlet bending pipe 2 and the second glue outlet bending pipe 3.

[0030] Specifically, the pressing assembly 7 includes an upper pressing block 71, a pressing rod 72, and a piston 73. The piston 73 is movably located in the pressing chamber 15. The pressing rod 72 is movably inserted into the pressing chamber 15 via the discharge knob switch 6, and the bottom end of the pressing rod 72 is connected to the piston 73, while the top end of the pressing rod 72 is connected to the upper pressing block 71.

[0031] Its working principle is as follows: First, open the sealing cover 5 and load the two components into the first material cylinder 11 and the second material cylinder 12 respectively. Then, turn the top of the discharge knob switch 6 to drive the closing block 61 to open the first air outlet 17 and the second air outlet 18 (normally closed). Then, manually press the upper pressure block 71 to drive the piston 73 to descend so that the first air pressure channel 13 and the second air pressure channel 14 simultaneously obtain equal air pressure. Under the action of air pressure, the components in the first material cylinder 11 and the second material cylinder 12 are extruded through the first glue outlet bending pipe 2 and the second glue outlet bending pipe 3 to the mixing extrusion head 4 and mixed. The mixed two-component adhesive is finally output to the object to be bonded through the mixing extrusion head 4.

[0036] Preferably, a third sealing ring 10 is provided between the first hollow column 51 and the first material cylinder 11, and a fourth sealing ring 20 is provided between the second hollow column 52 and the second material cylinder 12. This ensures the sealing performance between the structures.

[0037] Preferably, a first upper limit block 30 protrudes from the upper edge of the inner chamber wall of the first material cylinder 11. When the first hollow column 51 is engaged in the first material cylinder 11, it abuts against the first upper limit block 30. A second upper limit block 40 protrudes from the upper edge of the inner chamber wall of the second material cylinder 12. When the second hollow column 52 is engaged in the second material cylinder 12, it abuts against the second upper limit block 40. The first upper limit block 30 and the second upper limit block 40, while limiting the sealing cap 5, can also serve as the upper limit for the addition of components, ensuring that the addition amounts of the two components are consistent, and also allowing for pressure space at the top.
