Abstract
Description
Technical Field
[0001] This utility model relates to adhesive packaging tubing, and more particularly to a two-component adhesive packaging tubing. Background Technology
[0002] Currently, there are two main types of packaging for two-component adhesives on the market: separate A and B packaging and dedicated two-component tubing. Separate A and B packaging requires weighing, mixing, and applying the adhesive according to the specified ratio. Dedicated two-component tubing is packaged and stored with a fixed ratio. When used, it is extruded using a dedicated two-component caulking gun and mixed via a static mixer. Because the two-component tubing has a fixed ratio, eliminating the need for weighing, and uses a dedicated caulking gun for extrusion and static mixing, it is widely used in the market. However, due to tool limitations, two-component tubing cannot be applied using ordinary glass caulking guns; it can only be used with dedicated two-component caulking guns. There are many types of dedicated two-component caulking guns, and different capacities and ratios are often not interchangeable. Furthermore, dedicated two-component caulking guns are expensive, resulting in low market penetration. Conversely, single-component glass caulking guns are low-cost, widely available, and readily available through various purchasing channels.
[0003] Therefore, it is necessary to design a split-type two-component packaging tube that can be used with both single-component glue guns and two-component dedicated glue guns. Utility Model Content
[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to design a two-component adhesive packaging tube that can be extruded using either a single-component glass glue gun or a two-component dedicated glue gun, thus addressing different situations and improving the applicability of the two-component adhesive packaging tube.
[0005] To achieve the above objectives, this utility model provides a two-component adhesive packaging tube, comprising an inner cylinder and an outer cylinder, wherein the inner cylinder is detachably connected to the interior of the outer cylinder along the axial direction of the outer cylinder; the inner cylinder comprises a cylinder body and an adhesive dispensing part, wherein the adhesive dispensing part is located at the front end of the cylinder body, the cylinder body comprising an adjacent, straight-through first cavity and a straight-through second cavity, the adhesive dispensing part comprising an A dispensing nozzle and a B dispensing nozzle, wherein the A dispensing nozzle communicates with the first cavity and the B dispensing nozzle communicates with the second cavity, one end of the outer cylinder is provided with an opening and the other end is provided with a positioning hole, the adhesive dispensing part passing through the positioning hole and matching the positioning hole.
[0006] Furthermore, the dispensing part is also provided with two first limiting blocks, both of which are arc-shaped and on the same circumference, and the latches of the two first limiting blocks are both set inward.
[0007] Furthermore, the flow cross-sectional area of the first cavity is larger than that of the second cavity.
[0008] Furthermore, the outer cylinder is also provided with a positioning groove, the shape of which corresponds to the front end shape of the inner cylinder.
[0009] Furthermore, the dispensing part is also provided with a first limiting rib and a second limiting rib. The first limiting rib is disposed on the outer wall of the inner cylinder, and the second limiting rib is disposed on the outer wall of the first limiting block and is opposite to the first limiting rib. The positioning hole is provided with a limiting notch corresponding to the first limiting rib, and the positioning groove is provided with a limiting recess corresponding to the second limiting rib.
[0010] Furthermore, a V-shaped groove is provided between the A dispensing nozzle and the B dispensing nozzle, and a protrusion corresponding to the V-shaped groove is provided at the corresponding position of the positioning hole.
[0011] After adopting the above technical solution, the beneficial effects of this utility model are: the inner cylinder of the two-component adhesive packaging tube of this utility model is detachably connected to the inside of the outer cylinder along the axial direction of the outer cylinder, which can extrude the adhesive using a single-component glass glue gun or a two-component special glue gun, thereby improving the applicability of the two-component adhesive packaging tube.

[0018] The technical solution of this utility model will be further described below through embodiments:
[0019] This utility model provides a two-component adhesive packaging tube, combined with Figures 1-5 As shown, a two-component adhesive packaging tube includes an inner cylinder 2, an outer cylinder 1, and a dispensing mechanism. The inner cylinder 2 is detachably connected to the interior of the outer cylinder 1 along its axial direction. The inner cylinder 2 includes a cylinder body and a dispensing section, with the dispensing section located at the front end of the cylinder body. The cylinder body includes a first cavity 21 and a second cavity 22, both arranged adjacently and connected in a straight line. The dispensing section includes a dispensing nozzle A 23 and a dispensing nozzle B 25. Dispensing nozzle A 23 communicates with the first cavity 21, and dispensing nozzle B 25 communicates with the second cavity 22. One end of the outer cylinder 1 has an opening, and the other end has a positioning hole 11. The dispensing section passes through the positioning hole 11 and mates with it. If a single-component glue gun is selected, the inner cylinder 2 is inserted into the outer cylinder 1 for use with the single-component glue gun; if a two-component glue gun is selected, the inner cylinder 2 is directly inserted into the two-component glue gun for use.
[0020] Specifically, the volume ratio of the first cavity 21 and the second cavity 22 can be selected in the range of 5:1 to 12:1, and the first cavity 21 is filled with component A adhesive and the second cavity 22 is filled with component B adhesive.
[0021] Preferably, the capacity ratio of the first cavity 21 and the second cavity 22 is 10:1.
[0022] Specifically, the shape of the bottom connection between the first cavity 21 and the second cavity 22 matches the shape of the glue tube slot of the two-component glue gun.
[0023] Specifically, the dispensing part is also provided with two first limiting blocks 26. Both first limiting blocks 26 are arc-shaped and on the same circumference. The latches of the two first limiting blocks 26 are both set inward. One of the first limiting blocks 26 is provided with a positioning notch 29. The A dispensing nozzle 23 and the B dispensing nozzle 25 are provided with plugs 12. The plugs 12 are located outside the A dispensing nozzle 23 and the B dispensing nozzle 25. The inside of the plugs 12 is provided with a first rubber plug and a second rubber plug. The first rubber plug corresponds to the A dispensing nozzle 23 and the second rubber plug corresponds to the B dispensing nozzle 25. The outer circumferential surface of the plugs 12 is provided with two first protrusions corresponding to the first limiting blocks 26 and a second protrusion corresponding to the positioning notch 29. The second protrusion of the plugs 12 is aligned with the positioning notch and rotated 90 degrees to the right until the protrusion is aligned with the limiting block 26 to achieve a seal.
[0024] Specifically, the dispensing section can be used with a general static mixer. The plug 12 is removed and the static mixer is installed. The static mixer includes a mixing tube connector and a static mixing tube. The mixing tube connector has the same first protrusion and second protrusion as the plug 12, which can make the mixing tube connector lock with the dispensing section.
[0025] Specifically, the outer cylinder 1 is also provided with a positioning groove, the shape of which corresponds to the front end shape of the inner cylinder 2. When in use, the inner cylinder 2 is pushed into the positioning hole 11 along the positioning groove and can be used with a single-component glue gun.
[0026] Specifically, a V-groove 24 is provided between the A dispensing nozzle 23 and the B dispensing nozzle 25, and a protrusion corresponding to the V-groove 24 is provided at the corresponding position of the positioning hole 11.
[0027] Specifically, the dispensing section is also provided with a first limiting rib 27 and a second limiting rib 28. The first limiting rib 27 is disposed on the outer wall of the inner cylinder 2, and the second limiting rib 28 is disposed on the outer wall of the first limiting block 26 and is opposite to the first limiting rib 27. The positioning hole 11 is provided with a limiting notch 112 corresponding to the first limiting rib 27, and the positioning groove is provided with a limiting recess 111 corresponding to the second limiting rib 28. In use, the first limiting rib 27 and the second limiting rib 28 are respectively engaged with the limiting notch 112 and the limiting recess 111 to reinforce the connection between the inner cylinder 2 and the outer cylinder 1.
[0028] Specifically, the glue-expelling mechanism includes a base plate 15, a first push rod 13, a second push rod 14, a first piston, and a second piston. The first push rod 13 and the second push rod 14 are of the same length and are perpendicularly disposed on the base plate 15. The first push rod 13 presses against the first piston and cooperates with the first cavity 21, while the second push rod 14 presses against the second piston and cooperates with the second cavity 22. When the glue gun pushes the base plate 15, the first push rod 13 and the second push rod 14 simultaneously push the first piston and the second piston, causing the first piston and the second piston to slide axially along the first cavity 21 and the second cavity 22, respectively. This forces the A-component glue located in the first cavity 21 and the B-component glue located in the second cavity 22 into the static mixing tube for thorough mixing before extrusion.
[0029] It is worth mentioning that when the two-component adhesive packaging tube is used with a two-component dedicated glue gun, it does not need to be used with a glue pushing mechanism.
[0030] The specific working process of this two-component adhesive packaging tube is as follows:
[0031] When used with a single-component glass glue gun, insert the inner tube 2 into the outer tube 1 along the axial direction of the outer tube 1, pass the glue dispensing part through the positioning hole 11, and lock it in place by the first limiting rib 27 and the limiting notch 112. The second limiting rib 28 locks in place with the limiting recess 111, thus reinforcing the connection between the inner tube 2 and the outer tube 1. Rotate the plug 12 to open the A dispensing nozzle 23 and the B dispensing nozzle 25, insert the packaging tube into the single-component glass glue gun, and pull the trigger to drive the first push rod 13 and the second push rod 14 to squeeze the A component glue in the first cavity 21 and the B component glue in the second cavity 22 into the static mixing tube for thorough mixing and then extrusion. When used with a two-component special glue gun, simply insert the inner tube directly into the two-component special glue gun.
