Description

Technical Field

[0001] The utility model belongs to the technical field of polyurethane adhesive containers, in particular to a quantity-controlled polyurethane adhesive container. Background Art

[0002] Polyurethane adhesive is an adhesive containing specific groups, composed of isocyanate and polyester or polyether, etc. It is highly polar and active, and has good adhesion to various metal and non-metal materials. When using it, the type and proportion of the components can be adjusted to obtain a flexible or even hard adhesive layer. It can be cured at high temperature or at room temperature, and is widely used;

[0003] At present, in actual applications, it is found that when extracting polyurethane adhesive, it is impossible to know the remaining amount inside the container, and only a rough estimate can be made based on experience, which results in the residual amount of unused adhesive inside, which cannot be sealed in time, is not conducive to subsequent use, and causes waste and increases the cost of use.

[0004] In order to solve the above problems, the present application proposes a controlled-quantity polyurethane adhesive container. Utility Model Content

[0008] Furthermore, a convex seat is provided at the upper outer ring position of the double-layer cover for passing a draw cord, and a stopper is provided inside the double-layer cover near the upper position to resist the draw cord and prevent it from loosening outwards.

[0009] Furthermore, an air cavity and a positioning groove are provided inside the floating plate, the positioning groove is a longitudinal opening structure, and the air cavity is located between the outer wall of the positioning groove and the inner wall of the floating plate.

[0012] Furthermore, a pull ring is provided on the top of the plug tube, and a sealing strip is provided at the joint thereof to press against the pull rope and the inner wall of the limiting tube to form a seal.

[0013] Furthermore, the floating plate achieves a floating state through the air cavity to prevent tilting that affects the use of the pull rope.

[0014] The utility model has the following beneficial effects:

[0015] The utility model cooperates with the floating plate and the pull rope, and when the polyurethane adhesive is extracted, the floating plate drives the pull rope to automatically retract. At this time, the remaining amount of the polyurethane adhesive inside the storage barrel can be known by observing the position of the end of the pull rope, which is convenient for controlling the amount and sealing the remaining part, thereby ensuring stable performance and reducing waste during subsequent use.

[0028] Please refer to Figures 1-5 As shown, the present utility model is a quantitative control polyurethane adhesive container, including: a storage barrel 1; a double-layer cover 2 is provided inside the storage barrel 1 near the upper end, and a floating plate 5 is placed inside. The height of the floating plate 5 is adjusted by the change of the polyurethane adhesive liquid level, and then the pull rope 8 above it is recovered when the floating plate 5 descends. The remaining amount of the polyurethane adhesive inside is judged according to the circumferential proportion of the storage barrel 1 compared with the end position of the pull rope 8;

[0029] A boss 3 is provided in the area near the outer ring of the double-layer cover 2, and the extraction tube is automatically sealed by the sealing gasket 10 inside, and the polyurethane adhesive on the surface of the extraction tube is automatically scraped off by the scraper 11 below the sealing gasket 10 to prevent adhesion to the sealing gasket 10 and cause a fixed seal;

[0030] The present embodiment provides a polyurethane adhesive storage container with controllable internal remainder. By utilizing the cooperation of the floating plate 5 and the pull rope 8, the ratio of the internal remainder to the barrel capacity can be directly observed from the outside, which is convenient for timely sealing to ensure the subsequent storage effect and use quality. Secondly, the extraction tube can be automatically cleaned and the extraction port can be sealed to ensure timely sealing when there is residual polyurethane adhesive and prevent a large amount of air from entering and causing deterioration.

[0031] Among them, a protrusion 4 is provided at the upper outer circle position of the double-layer cover 2 for passing a draw rope 8, and a stopper 9 is provided at the upper position near the inside thereof to support the draw rope 8 and prevent it from loosening outwards. A notch is formed at one end of the draw rope 8 after being retracted, and the remaining amount of the internal polyurethane adhesive can be known by comparing the size of the notch with the circumference of the storage barrel 1.

[0032] An air cavity 6 and a positioning groove 7 are provided inside the floating plate 5 . The positioning groove 7 is a longitudinal opening structure. The air cavity 6 is located between the outer wall of the positioning groove 7 and the inner wall of the floating plate 5 .

[0033] A limiting tube 12 is installed inside the outer ring of the double-layer cover 2 and is in a relative position to the convex seat 4 .

[0034] A plug tube 13 is provided inside the limiting tube 12 and sleeved on the outside of the draw rope 8 for controlling the fixing state of the draw rope 8 when extracting the polyurethane adhesive.

[0035] A pull ring 14 is provided above the plug tube 13, and a sealing strip 15 is provided at the joint thereof to press against the pull rope 8 and the inner wall of the limiting tube 12 to form a seal, thereby ensuring smooth sliding during use and subsequent sealed airtight performance.

[0036] The floating plate 5 is in a floating state through the air cavity 6 to prevent the floating plate 5 from tilting and affecting the use of the pull rope 8 .

[0037] It can be understood that the utility model can directly observe the ratio of the internal remainder to the barrel capacity from the outside, which is convenient for timely sealing to ensure the subsequent storage effect and use quality. Secondly, it can also automatically clean the extraction tube and form a seal on the extraction port to ensure the timeliness of the sealing when there is residual polyurethane adhesive, and prevent a large amount of air from entering and causing deterioration.

[0038] A specific application of the operation process of this embodiment is as follows: When in use, first, due to the decrease in the liquid level of the polyurethane adhesive after extraction, the floating plate 5 automatically descends, driving the recovery of the pull rope 8. At this time, by observing the comparison between the end of the pull rope 8 and the circular convex edge part at the upper end of the storage barrel 1, the remaining amount of the polyurethane adhesive can be known, which is convenient for timely sealing storage and other treatments. In addition, when the polyurethane adhesive cannot be fully used, the sealing gasket 10 can automatically drive the scraper 11 to scrape its surface to form cleaning during the removal of the extraction pipe. Furthermore, the inner sides of the sealing gasket 10 are mutually extruded to form a pre-seal, which is convenient for subsequent sealing and other treatments. After this arrangement, the storage barrel 1 is more convenient for use at the construction site, improving its operation convenience and ensuring the subsequent storage effect and use quality of the remaining polyurethane adhesive.
