Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-4 As shown, the utility model provides a technical solution: comprising an auger assembly 1, a pretreatment assembly 2 is arranged on one side of the auger assembly 1, the auger assembly 1 comprises a conveying auger 101, the conveying auger 101 is arranged in an inclined manner, a feeding hopper 102 is fixedly installed on the top surface of one end of the conveying auger 101 located at the bottom, an injection pipe 103 is fixedly installed on the bottom surface of one end of the conveying auger 101 located at the top, the bottom end of the injection pipe 103 is fixedly connected to the top of the circular mouth 203, and the raw materials entering the conveying auger 101 through the feeding hopper 102 can be transported from the bottom end to the higher end by rotating the spiral conveying rod, and then the raw materials fall into the pretreatment chamber 202 through the injection pipe 103;

[0020] The pretreatment assembly 2 comprises a pretreatment tube body 201, a pretreatment chamber 202 is provided in the pretreatment tube body 201, a servo motor 205 is fixedly installed at the center of the top surface of the pretreatment tube body 201, the bottom end of the output shaft of the servo motor 205 extends to the top of the pretreatment chamber 202, and a square vertical rod 206 is fixedly installed at one end of the output shaft of the servo motor 205, a sleeved round rod 207 is slidably sleeved on the rod body of the square vertical rod 206, and a plurality of annular sleeves 208 are fixedly sleeved on the rod body of the sleeved round rod 207 from top to bottom in sequence, and the annular sleeve 208 is fixedly sleeved on the rod body of the sleeved round rod 207. 8 is fixedly installed with a plurality of stirring blades 209, the bottom of the rod body of the sleeved round rod 207 is fixedly sleeved with a rotating plate 210, and both sides of the rotating plate 210 are fixedly installed with an adjusting round rod 211, and the bottom of the pretreatment chamber 202 is fixedly installed with an annular plate 212. Under the action of the adjusting round rod 211, the stirring blades 209 can move up and down while rotating and stirring, so that the polyurethane adhesive raw material can be turned up and down while rotating and stirring, effectively improving the mixing efficiency, and the polyurethane adhesive raw material can be mixed and fed, which is more practical.

[0021] In this embodiment, a circular opening 203 is opened on one side of the top surface of the pretreatment tube body 201 , and a material conveying pipe 204 is opened in the middle of the bottom surface of the pretreatment tube body 201 .

[0022] A plurality of trapezoidal grooves 213 are provided on the top surface of the annular plate 212, and the plurality of trapezoidal grooves 213 are evenly distributed on the top surface of the annular plate 212.

Then, under the action of the adjusting round rods 211, the stirring blades 209 can move up and down while rotating and stirring, so that the polyurethane adhesive raw material can be turned up and down while rotating and stirring, thereby effectively improving the mixing efficiency, and the polyurethane adhesive raw material can be mixed and fed, which is more practical.

[0024] In summary, the polyurethane adhesive production feeding device sets the conveying auger 101 to an inclined state, so that the staff can load the material at the lower end, making the loading more convenient and quick, and reducing a certain amount of labor intensity. At the same time, by allowing the stirring blade 209 to move up and down while rotating and stirring, the polyurethane adhesive raw material can be turned up and down while rotating and stirring, thereby effectively improving the mixing efficiency, and the polyurethane adhesive raw material can be mixed and fed, which is more practical.
