DETAILED DESCRIPTION

[0030] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0031] like Figure 1 As shown, a method for producing a high-strength polyurethane adhesive comprises the following steps:

[0032] Step 1, pouring raw materials into the mixing barrel 3 of the production equipment, the raw materials are polyether polyol, polyester polyol, isocyanate (such as TDI, MDI, etc.), catalyst (such as organic tin, tertiary amine, etc.), solvent (such as toluene, DMF, etc.) and other necessary additives (such as softener, thickener, tackifier, etc.), moving the mixing barrel 3 to the inner side of the fixed base 1, using the screw to drive the threaded sleeve 14, so that the threaded sleeve 14 drives the limit clamp 10 to move up and down, by rotating the adjusting bolt 11, the threaded structure is used to drive the two groups of movable clamp arms 12 to translate, so that the two groups of movable clamp arms 12 are respectively clamped on both sides of the mixing barrel 3;

[0033] Step 2: Use the lifting rod 8 to drive the lifting arm 7, so that the lifting arm 7 drives the stirring rod 4 to move downward, and the stirring rod 4 is moved to the inside of the mixing barrel 3, and the motor 21 is started, so that the motor 21 drives the stirring rod 4 to rotate by the chain, and the raw materials of the polyurethane adhesive are mixed;

[0034] Step three, move the stirring rod 4 upward, take the stirring rod 4 out of the mixing barrel 3, after moving out of the mixing barrel 3, open the water collecting tray 2, place the water collecting tray 2 under the stirring rod 4, and use the flushing ring 5 to flush the stirring rod 4.

[0035] like Figure 2 As shown, a production equipment for high-strength polyurethane adhesive includes a fixed base 1 and a lifting column 9. The lifting column 9 is fixedly installed in the middle position of the upper outer surface of the fixed base 1. A limit clamp 10 is movably installed on the side outer surface of the lifting column 9. A mixing barrel 3 is provided on the inner side of the fixed base 1 and the limit clamp 10. A stirring rod 4 is movably installed inside the mixing barrel 3. The polyurethane adhesive is made by mixing a variety of raw materials. Different raw materials need to be mixed in sequence before processing. When the raw material mixing operation of this embodiment is performed, the corresponding mixing barrel 3 needs to be placed in the production equipment, and the mixing operation is completed by using the stirring rod 4. The limit clamp 10 plays an auxiliary fixing role on the mixing barrel 3 to avoid shaking of mixing barrels 3 of different sizes.

[0036] In order to solve the installation and fixation problems of different raw material barrels, such as Figure 3 As shown, the limit clamp 10 includes a lifting frame 20 and two groups of movable clamp arms 12. The two groups of movable clamp arms 12 are movably installed on the front end outer surface of the lifting frame 20. The lifting frame 20 and the two groups of movable clamp arms 12 are movably connected through an adjusting bolt 11. In order to meet the fixing operation of mixing barrels 3 of different sizes, the adjusting bolt 11 is rotated so that the adjusting bolt 11 drives the movable clamp arms 12 to move using a threaded structure, and the distance between the two groups of movable clamp arms 12 is adjusted so that the two groups of movable clamp arms 12 are respectively clamped and fixed on both sides of the mixing barrel 3.

[0037] The lifting frame 20 is movably sleeved on the outer surface of the lifting column 9, and the lifting frame 20 and the lifting column 9 are slidingly connected through the lifting block 13. A threaded sleeve 14 is provided in the middle of the rear end of the lifting frame 20. The threaded sleeve 14 is driven by a screw rod, so that the threaded sleeve 14 drives the lifting frame 20 to move up and down, thereby adjusting the clamping height of the two sets of movable clamp arms 12.

[0038] To solve the cleaning problem when mixing different raw materials, such as Figure 4 As shown, a water collecting tray 2 is movably installed on one side of the lifting column 9. The lifting column 9 and the water collecting tray 2 are movably connected by a rotating rod 18. A drain pipe 19 is fixedly installed on the lower end of the water collecting tray 2. When stirring different raw materials, it is necessary to rinse the stirring rod 4 after use to prevent other raw materials from adhering to the surface of the stirring rod 4.

A diverter 17 is provided at the upper end of the flushing ring 5. The flushing ring 5 and the diverter 17 are fixed to each other via a diverter pipe 16. A nozzle 15 is provided at the bottom of the flushing ring 5. A connecting pipe 6 is installed on one side of the diverter 17. The connecting pipe 6 is used to introduce water into the diverter 17, so that the diverter 17 moves through the diverter pipe 16 to introduce water into the two groups of nozzles 15, and the two sides of the stirring rod 4 are flushed through the nozzles 15.

[0041] The invention discloses a production method and production equipment of a high-strength polyurethane adhesive. The conventional adhesive mixing equipment adopts an integrated structural design, so that its barrel structure is integrated with the entire equipment. When performing the mixing operation of different raw materials, the barrel needs to be emptied and cleaned after use, which increases the operation steps and cannot be applied to different barrel structures.

[0042] To this end, by setting a limit clamp 10, when the production equipment performs a mixing processing operation of the high-strength polyurethane adhesive raw material, it can complete the installation and fixation of mixing barrels 3 of different specifications, thereby improving the efficiency of mixing different raw materials, and there is no need to empty and clean the barrel body. When in use, the raw materials are poured into the mixing barrel 3 of the production equipment, and the mixing barrel 3 is moved to the inner side of the fixed base 1. First, the height of the limit clamp 10 is adjusted according to the height of the mixing barrel 3, and the lead screw is driven by the motor, and then the lead screw is used to drive the threaded sleeve 14, so that the threaded sleeve 14 drives the limit clamp 10 to move up and down. After the limit clamp 10 is moved to the corresponding height, the adjusting bolt 11 is rotated to drive the two groups of The movable clamping arm 12 is translated, so that the two groups of movable clamping arms 12 are respectively clamped on both sides of the mixing barrel 3, so as to meet the installation and fixation of mixing barrels 3 of different diameters, so that the stirring rod 4 is placed in the middle position of the mixing barrel 3, and the lifting arm 7 is driven by the lifting rod 8, so that the lifting arm 7 drives the stirring rod 4 to move downward, and the stirring rod 4 is moved to the inside of the mixing barrel 3, and the motor 21 is started, so that the motor 21 drives the stirring rod 4 to rotate by the chain to complete the mixing of the raw materials of the polyurethane adhesive. During the mixing operation, although the mixing barrel 3 adopts a split structure design, the setting of the limit clamp 10 can complete the auxiliary fixation of the mixing barrel 3 during the mixing operation, so that the mixing barrel 3 remains in a relatively stable state;

[0043] Secondly, when the mixing equipment is mixing different raw materials, the residual raw materials will adhere to the surface of the stirring rod. Direct mixing will cause the raw materials to be mixed. The stirring rod needs to be cleaned manually after use, and the functionality is single.

[0044] To this end, by setting a water collecting tray 2 and a flushing ring 5, when the production equipment performs a mixing process of different raw materials of the high-strength polyurethane adhesive, the flushing operation of the stirring rod 4 can be automatically completed to avoid the mixing of different raw materials and improve the processing effect of the high-strength polyurethane adhesive; move the stirring rod 4 upward and take it out of the mixing barrel 3. After moving out of the mixing barrel 3, open the water collecting tray 2 so that the water collecting tray 2 is placed under the stirring rod 4. When the different raw materials are stirred, the stirring rod 4 needs to be flushed after use to avoid other raw materials adhering to the surface of the stirring rod 4. The water collecting tray 2 collects the liquid under flushing, and the flushing ring 5 is used to flush the stirring rod 4. The water body is introduced into the diverter 17 through the connecting pipe 6, so that the diverter 17 moves through the diverter pipe 16 to introduce the water body into the two groups of nozzles 15, and the two sides of the stirring rod 4 are flushed from top to bottom through the nozzles 15, so that the water body flows into the water collecting tray 2 along the stirring rod 4 and is discharged outward through the drain pipe 19 of the water collecting tray 2.
