[0030] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0031] A storage device for the production of PU glue, comprising an inner tank body 1, a sealing and drying mechanism 3 is installed at the upper end of the inner tank body 1, a glue discharging mechanism 4 is fixedly connected to the outer surface of the inner tank body 1, a water pipe 6 is fixedly connected to the outer surface of the inner tank body 1, a plurality of heating wires 5 are fixedly connected to the outer surface of the inner tank body 1, and one ends of the plurality of heating wires 5 away from the inner tank body 1 are jointly fixedly connected to an outer tank body 2.

[0032] In this embodiment, the glue discharging mechanism 4 includes a lower glue pipe 41, a fixing frame 42 is fixedly connected to the outer surface of the lower glue pipe 41, two sliding grooves 43 are opened on the lower inner wall of the fixing frame 42, a glue passing valve 44 is movably connected to the upper end of the fixing frame 42, two sliding plates 45 are slidably connected to the inner walls of the two sliding grooves 43, a sealing baffle 46 is jointly fixedly connected to the lower ends of the two sliding plates 45, and a sealing gasket 47 is fixedly connected to the rear end of the sealing baffle 46; the outer surface of the lower glue pipe 41 is fixedly connected to the inner tank body 1, the water pipe 6 is spirally distributed, and the heating wires 5 are annularly distributed; the glue passing valve 44 includes a rotating handle 441, a rotating rod 442 is fixedly connected to the lower end of the rotating handle 441, and a flow stopping block 443 is fixedly connected to the outer surface of the rotating rod 442; the outer surface of the rotating rod 442 is movably connected to the fixing frame 42, the outer surface of the flow stopping block 443 is movably connected to the lower glue pipe 41, and the flow stopping block 443 is in a hemispherical structure.

[0033] Through the above solution: During use, it can simply and directly respond to production requirements, quickly and accurately control the outflow of PU glue, avoid equipment electrical connection failures that may occur in automation, improve safety and stability and production efficiency. Through the sealed glue discharging valve system, it can reduce the pollution of PU glue by external impurities, ensure the purity and quality stability of the product, effectively prevent the leakage of PU glue during storage and glue discharging, and ensure the safety of the production environment.

[0034] In this embodiment, the sealing and drying mechanism 3 includes a cover plate 31. A handle 32 is fixedly connected to the upper end of the cover plate 31. A clamping groove 33 is formed in the lower end of the cover plate 31. A sealing ring 34 is fixedly connected to the lower end of the cover plate 31. Two clamping blocks 35 are installed in the clamping groove 33. A plurality of springs 36 are fixedly connected to the mutually approaching ends of the two clamping blocks 35. A storage box 37 is fixedly connected to the lower ends of the two clamping blocks 35. Vent holes 38 are formed in both the left end and the right end of the storage box 37. The lower end of the cover plate 31 is fixedly connected to the inner tank body 1.

[0035] Through the above solution: PU glue is prone to moisture absorption in a humid environment, resulting in performance degradation, such as weakened adhesion and extended curing time. The sealing and drying mechanism effectively isolates external moisture and keeps the storage environment dry, thereby protecting the quality of PU glue from being affected.

[0036] It should be noted that the present utility model is a storage device for PU glue production. During use, first pull up the handle 32 upward. At the same time, place desiccant in the storage box 37. First, insert the right side of the clamping block 35 on the right into the clamping groove 33 preferentially, and then apply a rightward force to the clamping block 35 on the left. At this time, the spring 36 contracts, that is, the clamping block 35 on the left can be inserted into the clamping groove 33, which can effectively isolate external humid air, absorb excess moisture in the tank, prevent the PU glue from absorbing moisture and deteriorating, thereby extending its shelf life, reducing waste caused by the deterioration of the PU glue due to moisture absorption, and reducing production costs. Using non-deteriorated PU glue due to moisture absorption for production can ensure that the quality and performance of the product meet the design requirements and improve the market competitiveness of the product. When the PU glue may undergo chemical reactions after being affected by moisture, releasing harmful gases or causing other safety hazards, the storage safety is enhanced; when the glue needs to be taken out for use, manually rotate the rotating handle 441. The rotating handle 441 drives the rotating rod 442 and the flow-stop block 443 to rotate. At the same time, pull the sealing baffle 46 forward. The sealing baffle 46 drives the sliding plate 45 to slide on the inner wall of the sliding groove 43. When sliding to the rear end of the fixed frame 42, the PU glue flows out. During use, it can simply and directly respond to production requirements, quickly and accurately control the outflow of the PU glue, avoid possible equipment electrical connection failures caused by automation, and at the same time avoid glue leakage; finally, when the storage temperature environment of the glue is relatively low and does not meet the storage conditions, connect the heating wire 5 to the power supply to heat. When the temperature is relatively high, water at a suitable temperature can be passed into the water pipe 6 to help the glue storage conditions reach a suitable temperature. The appropriate storage temperature can prevent the PU glue from softening, melting or decomposing due to too high temperature, and can also prevent freezing or hardening due to too low temperature. These physical changes will directly affect the adhesion, fluidity and use effect of the glue. At the same time, unnecessary chemical reactions are avoided, so as to maintain its original performance characteristics and extend the shelf life of the glue.
