Description

Technical Field

[0001] This utility model relates to the field of piston-type double-tube packaging technology, specifically to piston-type double-tube packaging for preventing AB glue curing residue. Background Technology

[0002] AB glue is a two-component adhesive, which is formed by mixing the glue and a hardener and curing at room temperature. It can be cured without heating and is widely used in industries, model making and other fields. It mainly contains acrylic, epoxy resin, polyurethane, etc. Different formulations determine its properties, such as viscosity and temperature resistance. Its main function is to bond two objects of different materials together. It has strong adhesion and durability and can maintain a stable bonding effect in a variety of environments. This device is the piston-type double tube packaging of AB glue.

[0003] When extruding adhesive in a piston-type dual-tube packaging, some adhesive remains at the extrusion port. If it solidifies, it can affect subsequent adhesive extrusion operations.

[0004] Therefore, a piston-type dual-tube packaging for preventing AB glue curing residue is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a piston-type double-tube packaging for preventing AB glue curing residue, so as to solve the problem mentioned in the background art that piston-type double-tube packaging is not convenient for handling extruded glue residue.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a piston-type dual-tube packaging for preventing AB glue curing residue, comprising a first tube, a second tube, and an extrusion tube. The second tube is fixed to the left side of the first tube. A connecting platform is fixed to the bottom ends of the first and second tubes. A flow channel is provided inside the connecting platform. An extrusion tube is fixed to the center of the bottom end of the connecting platform. An extrusion port is provided at the center of the bottom end of the extrusion tube. A residual material discharge assembly is provided on the outside of the extrusion tube. The residual material discharge assembly includes a sliding sleeve, a discharge pipe, a discharge hole, and a spring. A sliding sleeve is movably installed on the outside of the extrusion tube. A discharge pipe is fixed to the center of the bottom end of the sliding sleeve. A discharge hole is provided inside the discharge pipe. A spring is installed at the top end of the sliding sleeve.

[0007] As a further technical solution of this utility model, a rotating shaft is provided inside the flow channel, and positioning shafts are fixed at both ends of the rotating shaft. A material feeding plate is fixed on the outer wall of the rotating shaft.

[0008] As a further technical solution of this utility model, the rotating shaft is provided in two sets inside the flow channel, and the two sets of rotating shafts are symmetrically distributed.

[0009] As a further technical solution of this utility model, several material feeding plates are fixed on the outer side wall of the rotating shaft, and the several material feeding plates are arranged in a ring.

[0010] As a further technical solution of this utility model, a first piston is provided inside both the first rubber tube and the second rubber tube, and an inner cavity is provided inside the first piston.

[0011] As a further technical solution of this utility model, a top plate is fixed to the top of the inner cavity, and a through groove is provided on the surface of the top of the top plate.

[0012] As a further technical solution of this utility model, a second piston is movably installed inside the inner cavity, and a bottom hole is provided at the center of the bottom end of the first piston.

[0013] As a further technical solution of this utility model, a locking block is provided inside the bottom hole, and a barrier plate is fixed at the bottom end of the locking block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a sliding sleeve, the sliding sleeve is used on the outside of the extrusion tube and is kept elastically connected by a spring. When the glue is extruded, it is discharged along the flow channel, extrusion tube, extrusion port and discharge tube. If some residual glue remains in the discharge hole inside the discharge tube, pressing the sliding sleeve will cause the sliding sleeve to move upward along the extrusion tube during the compression of the spring. In this way, the residual glue located inside the discharge tube can be pushed out, preventing the residual glue from blocking the discharge hole inside the discharge tube. This realizes the anti-clogging function when the piston-type double tube packaging is used.

[0015] With the help of the positioning shaft, two sets of rotating shafts are symmetrically distributed inside the flow channel. During the extrusion process of the glue liquid inside the first and second glue tubes, when it enters the flow channel, it can push the two sets of rotating shafts to rotate. When the material feeding plate on the outside of the first glue tube rotates accordingly, it can assist in the mixing operation of the two sets of glue liquids, thus realizing the auxiliary mixing function of the piston-type dual-tube packaged glue liquid.

[0016] By incorporating a second piston located within the inner cavity of the first piston, a small amount of adhesive remains inside the first and second tubing after the first piston moves down to the bottom and completes the adhesive contact operation. At this point, the second piston, located inside the first piston, can be pressed down, causing the locking block inside the bottom hole to be ejected. After separating the barrier plate, the second piston's downward movement helps to discharge the residual adhesive inside the first and second tubing, thus achieving the residual adhesive discharge function of this piston-type dual-tube packaging.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 An embodiment of this utility model provides a piston-type dual-tube packaging for preventing AB glue curing residue, including a first tube 1, a second tube 2, and an extrusion tube 5. The second tube 2 is fixed to the left side of the first tube 1. A connecting platform 3 is fixed to the bottom end of the first tube 1 and the second tube 2. A flow channel 4 is provided inside the connecting platform 3. An extrusion tube 5 is fixed to the center of the bottom end of the connecting platform 3. An extrusion port 6 is provided at the center of the bottom end of the extrusion tube 5. A residual material discharge component is provided on the outside of the extrusion tube 5. The residual material discharge component includes a sliding sleeve 7, a discharge pipe 8, a discharge hole 9, and a spring 10. The sliding sleeve 7 is movably installed on the outside of the extrusion tube 5. The discharge pipe 8 is fixed to the center of the bottom end of the sliding sleeve 7. A discharge hole 9 is provided inside the discharge pipe 8. A spring 10 is installed on the top of the sliding sleeve 7.

[0024] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when in use, the adhesive inside the first tube 1 and the second tube 2 enters the flow channel 4, then enters the sliding sleeve 7 through the extrusion tube 5 and the extrusion port 6, and finally exits through the discharge tube 8 on the bottom side of the sliding sleeve 7. After exiting, the sliding sleeve 7, which is sleeved on the outside of the extrusion tube 5, can be pressed. During the upward movement of the sliding sleeve 7, the residual adhesive remaining in the discharge tube 8 can be squeezed out.

[0025] The flow channel 4 is provided with a rotating shaft 11. There are two sets of rotating shafts 11 inside the flow channel 4. The two sets of rotating shafts 11 are symmetrically distributed. Both ends of the rotating shaft 11 are fixed with positioning shafts 12. The outer wall of the rotating shaft 11 is fixed with a material-pulling plate 13. Several material-pulling plates 13 are fixed on the outer wall of the rotating shaft 11. The several material-pulling plates 13 are arranged in a ring.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, during use, two sets of rotating shafts 11 are movably installed inside the flow channel 4. When the adhesive liquid inside the first adhesive tube 1 and the second adhesive tube 2 enters the flow channel 4, it can push the material feeding plate 13 to rotate inside the flow channel 4. The rotating material feeding plate 13 can assist in stirring the two sets of adhesive liquid inside the flow channel 4 and assist in their mixing process.

[0027] The first hose 1 and the second hose 2 are both provided with a first piston 14. The first piston 14 is provided with an inner cavity 15. The top of the inner cavity 15 is fixed with a top plate 16. The surface of the top of the top of the top plate 16 is provided with a through groove 17. The second piston 18 is movably installed inside the inner cavity 15. The bottom of the first piston 14 is provided with a bottom hole 19 at the center. The bottom hole 19 is provided with a locking block 20. The bottom of the locking block 20 is fixed with a baffle plate 21.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, when in use, the first piston 14 is pushed down along the inner wall of the first tube 1 and the second tube 2 to perform normal glue extrusion. After the first piston 14 moves to the bottom side, the second piston 18 located inside the first piston 14 can be pressed down further. After the bottom barrier plate 21 is separated, the gas is pushed out through the bottom hole 19, which can help squeeze out the remaining glue.

[0029] Working principle: During use, the first piston 14 located inside the first hose 1 and the second hose 2 is pushed downwards, which pushes the adhesive inside the first hose 1 and the second hose 2 to enter the flow channel 4 simultaneously. When entering, it pushes the rotating shaft 11 inside the flow channel 4 to rotate. When the material feeding plate 13 on the outer wall rotates, it can assist in mixing the two sets of adhesives. The mixed adhesive enters the extrusion tube 5 along the flow channel 4, and then enters the sliding sleeve 7 along the extrusion port 6. Finally, it is discharged along the discharge tube 8. After the extrusion is complete, the sliding sleeve 7 can be pressed further. As the sliding sleeve 7 moves upward along the extrusion tube 5, the remaining glue inside the discharge tube 8 can be squeezed out. After the first piston 14 moves to the bottom position inside the first glue tube 1 and the second glue tube 2, it is difficult to squeeze out the remaining glue by means of the first piston 14. At this time, the second piston 18 located inside the first piston 14 can be pressed down further. After the bottom baffle plate 21 is separated, the gas is pushed out through the bottom hole 19, which can help squeeze out the remaining glue for use.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
