Description

Technical Field

[0001] The utility model relates to the technical field of reactor discharging, in particular to a PUR reactive hot melt adhesive discharging device. Background Art

[0002] Hot melt adhesive is a plastic adhesive that is popular because of its advantages such as easy packaging, transportation, storage, solvent-free, pollution-free, non-toxic, simple production process, high bonding strength and fast speed. The reactor is one of the main equipment for the production and processing of hot melt adhesive. After the hot melt adhesive is stirred and mixed inside the reactor, it needs to be discharged.

[0003] For the hot melt adhesive reactor for PUR reaction processing, refer to patent number: CN214514598U, a hot melt adhesive reactor discharge device, which includes a discharge pipe arranged on the reactor and an opening and closing mechanism for controlling the opening and closing of the discharge port of the discharge pipe, ensuring the normal discharge of the hot melt adhesive, and workers can choose the number of electric heating wires to be energized according to the weather temperature, so that workers can control the time required for the solidified hot melt adhesive to melt. This application can ensure the normal discharge of the hot melt adhesive.

[0004] However, the hot melt adhesive reactor discharge device has a very slow discharge rate due to the poor fluidity of the hot melt adhesive itself, which affects the production efficiency of the hot melt adhesive. In addition, the hot melt adhesive contains a large number of bubbles due to the stirring effect, and direct discharge will result in poor quality of the hot melt adhesive.

[0026] Specifically, through the coordination among the reactor body 1, the control panel 2, the first discharge pipe 3, the first discharge valve 4, the motor 5, the rotating rod 6, the fan blades 7, the threaded grooves 8, the threaded tube 9, the defoaming net 10 and other structures, when the hot melt adhesive is discharged through the first discharge pipe 3, the fan blades 7 cooperate with the rotation of the rotating rod 6 to push the hot melt adhesive downward. Combined with the falling force of the hot melt adhesive itself, the discharge efficiency of the hot melt adhesive can be effectively accelerated, and the bubbles generated in the hot melt adhesive can be eliminated during discharge.

[0027] In this embodiment: the output end of the motor 5 is fixedly connected to the left surface of the rotating rod 6, and the outer surface of the fan blade 7 is coated with a PTFE coating.

[0028] Specifically, PTFE coating is a special coating made of polytetrafluoroethylene (PTFE for short) and has excellent anti-stick properties.

[0029] In this embodiment, the threaded pipe 9 is connected to the threaded groove 8 in a corresponding threaded manner, and the defoaming net 10 is arranged in a corresponding manner to the first discharge pipe 3 .

[0030] Specifically, the defoaming net 10 can be quickly disassembled and installed on the first discharge pipe 3 through the threaded pipe 9 .

[0031] Working principle: When the reactor body 1 is used to process the hot melt adhesive for PUR reaction, the reactor is controlled by the control panel 2. After the hot melt adhesive is formed, the threaded tube 9 is engaged with the threaded groove 8 on the first discharge pipe 3 for positive rotation, the defoaming net 10 is located directly below the first discharge pipe 3, the first discharge valve 4 is opened, and the hot melt adhesive in the reactor body 1 flows downward through the first discharge pipe 3, and then the collection tool is used to collect the hot melt adhesive corresponding to the first discharge pipe 3, and the motor 5 is turned on at the same time, and the motor 5 drives the rotating rod 6 to move the fan blade 7 rotates in the first discharge pipe 3. Through the rotation of the fan blade 7, the hot melt adhesive that flows slowly in the first discharge pipe 3 due to viscosity can be quickly pushed downward to speed up the flow of the hot melt adhesive. The coating on the surface of the fan blade 7 effectively avoids the adhesion of the hot melt adhesive. The hot melt adhesive flowing downward in the first discharge pipe 3 passes through the defoaming net 10, and then the bubbles inside are eliminated to ensure the quality of the hot melt adhesive. After collection, the threaded tube 9 can be reversed through the threaded groove 8, and the defoaming net 10 can be removed from the first discharge pipe 3 for cleaning.

[0035] Specifically, through the coordination among the second discharge pipe 11, the second discharge valve 12, the piston push 13, the discharge port 14, the slot 15 and other structures, the hot melt adhesive in the reactor can be quantitatively extracted, which is convenient for detecting the reaction quality of the hot melt adhesive and adjusting the control parameters of the reactor.

[0036] In this embodiment, the notch 15 is arranged corresponding to the discharge port 14 , and the second discharge pipe 11 is communicated with the inside of the discharge port 14 .

[0037] Specifically, the hot melt adhesive in the second discharge pipe 11 can fall out of the discharge port 14 through the notch 15 .

[0038] Working principle: When the reactor body 1 is used to process PUR reaction hot melt adhesive, the second discharge valve 12 can be opened and the piston pusher 13 in the second discharge pipe 11 can be pulled outward to extract a certain amount of hot melt adhesive in the reactor body 1. Then the second discharge valve 12 can be closed, and the hot melt adhesive flows into the second discharge pipe 11, and then flows out from the discharge port 14 through the slot 15. The hot melt adhesive flowing out of the discharge port 14 is collected and tested, and the processing quality of the hot melt adhesive in the reactor body 1 can be tested in real time.
