Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0028] Embodiment:

[0029] A glue heating and stirring device, such as Figure 1 As shown, it includes a tank body 1, a heating structure, and a stirring structure 3; the heating structure is disposed on the side wall of the tank body 1, and the stirring structure 3 is connected to the tank body 1; as shown... Figure 2 as well as Figure 3 As shown, the stirring structure 3 includes a drive mechanism 2, a main stirring shaft 18, main stirring blades 6, an auxiliary stirring shaft 13, a connecting piece, and auxiliary stirring blades 14. The main stirring shaft 18 and the auxiliary stirring shaft 13 are rotatably connected to the tank body 1. The auxiliary stirring shafts 13 are evenly spaced along the circumferential direction on the outer side of the main stirring shaft. The drive mechanism 2 is used to drive the main stirring shaft 18 to rotate. The auxiliary stirring shafts 13 are connected to the main stirring shaft 18 through the connecting piece. The main stirring blades 6 are connected to the main stirring shaft 18, and the auxiliary stirring blades 14 are connected to the auxiliary stirring shaft 13.

[0030] The tank 1 has an inlet 5 on one side of its top and an outlet 17 on one side of its bottom. During use, glue and raw materials are added to the tank 1 through the inlet 5. The heating structure, such as the electric heating plate 15 or electric heating tube, is activated to heat the glue in the tank 1, maintaining a constant temperature after reaching the specified temperature. The drive mechanism 2 is then activated, causing the main stirring shaft 18 to rotate. The main stirring shaft 18 stirs the glue in the tank 1 through the main stirring blades 6. Simultaneously, the main stirring shaft 18 drives the auxiliary stirring shaft 13 to rotate through a connecting piece. The auxiliary stirring shaft 13 stirs the glue through the auxiliary stirring blades 14. The main stirring shaft 18's primary function is to stir the glue in the central area and promote the flow of glue within the tank 1. The auxiliary stirring shafts 13 and auxiliary stirring blades 14 stir the glue on the outer sides. This design ensures thorough stirring of the glue in the tank 1, improving the stirring effect and guaranteeing the quality of the produced glue.

[0031] In a preferred embodiment, such as Figure 2 As shown, a jacket is provided on one side of the outer wall of the bottom of the tank 1. The heating mechanism uses an electric heating plate 15, which is disposed within the jacket. The electric heating plate 15, located within the jacket of the outer wall of the bottom of the tank 1, can directly heat the adhesive at the bottom of the tank 1. The heat transfer distance is short and concentrated, which can quickly raise the temperature of the adhesive and improve heating efficiency. The jacket provides protection for the electric heating plate 15, preventing it from direct contact with the adhesive, reducing the risk of corrosion or damage, and extending the service life of the electric heating plate 15. Heat is transferred through the bottom of the tank 1, allowing the adhesive to be heated evenly from the bottom up. Combined with the stirring structure 3, this further improves the overall heating uniformity of the adhesive, thereby ensuring the quality of the adhesive.

[0032] In a preferred embodiment, such as Figure 2As shown, an upper mounting bracket 12 is fixedly connected to the top of the tank body 1, and a lower mounting bracket 16 is fixedly connected to the side of the tank body 1 near the bottom. The two sides of the main stirring shaft 18 are rotatably connected to the upper mounting bracket 12 and the lower mounting bracket 16, respectively. The two sides of the auxiliary stirring shaft 13 are also rotatably connected to the upper mounting bracket 12 and the lower mounting bracket 16, respectively. The upper mounting bracket 12 and the lower mounting bracket 16 provide a stable support structure for the main stirring shaft 18 and the auxiliary stirring shaft 13, ensuring that the stirring shafts will not shake or deviate when rotating at high speed, making the stirring process more stable and reliable.

[0033] In a preferred embodiment, such as Figure 3 As shown, both the upper mounting frame 12 and the lower mounting frame 16 have a cross-shaped structure. The upper mounting frame 12 and the lower mounting frame 16 are symmetrically arranged on both sides of the tank body 1. Four auxiliary stirring shafts 13 are provided. The main stirring shaft 18 is connected to the middle of the upper mounting frame 12 and the lower mounting frame 16. The four auxiliary stirring shafts 13 are respectively positioned near the ends of the upper mounting frame 12 and the lower mounting frame 16. The symmetrical arrangement of the cross-shaped upper mounting frame 12 and the lower mounting frame 16 provides stable support for the stirring shafts, ensuring stability during the stirring process and reducing shaking and vibration. Simultaneously, the four auxiliary stirring shafts 13, located at the ends of the mounting frames, cooperate with the main stirring shaft 18 in the middle, enabling more comprehensive coverage of the space inside the tank body 1 and improving the uniformity of stirring.

[0034] In a preferred embodiment, such as Figure 1 As shown, several support legs 4 are fixed to one side of the bottom of the tank 1. The support legs 4 provide reliable support for the tank 1, allowing it to be placed stably and preventing the tank 1 from shaking or tipping over due to its own weight or operations such as stirring. By supporting the tank 1 to a certain height, it is convenient to unload materials.

[0035] In a preferred embodiment, such as Figure 2 As shown, the drive mechanism 2 includes a motor 10 and a reducer 9. The motor 10 is fixed to the top of the tank 1, and the reducer 9 is connected to the motor 10. The top of the main stirring shaft 18 is connected to the reducer 9. The motor 10 provides the power source for the entire stirring device, ensuring that the main stirring shaft 18 can rotate continuously, thereby realizing the stirring operation of the adhesive in the tank 1. The reducer 9 can reasonably adjust the speed and torque output of the motor 10 according to the actual stirring requirements. For adhesives of different viscosities and volumes, it can adjust to a suitable stirring speed and force to ensure the best stirring effect.

[0036] In a preferred embodiment, such as Figure 3As shown, the connecting piece includes a driving wheel 8, a driven wheel 11 and a belt 7, wherein the driving wheel 8 is fixedly connected with the main stirring shaft 18, the driven wheel 11 is fixedly connected with the auxiliary stirring shaft 13, and the belt 7 is used to connect the driving wheel 8 and the driven wheel 11. Through the cooperation of the driving wheel 8, the driven wheel 11 and the belt 7, the power of the main stirring shaft 18 can be effectively transmitted to the auxiliary stirring shaft 13, so that the auxiliary stirring shaft 13 can rotate together with the main stirring shaft 18, realizing the cooperative stirring of the glue in different regions in the tank body 1 and guaranteeing the orderly development of the whole stirring work. The belt 7 transmission mode has a certain flexibility, and in the case that there is a certain interval and angle change in the position layout of each stirring shaft, the power transmission can still be well completed, which is convenient for reasonably arranging the positional relationship between the main stirring shaft 18 and the auxiliary stirring shaft 13 according to the internal space structure and stirring demand of the tank body 1, and optimizing the overall stirring layout.

[0037] In a preferred embodiment, as shown in Figure 4 The main stirring blade 6 includes a connecting disc 19 and a main paddle 20, wherein the connecting disc 19 is fixedly connected with the main stirring shaft 18, and the main paddle 20 is fixedly connected with the connecting disc 19 and is uniformly and circumferentially spaced on the connecting disc 19. The fixed connection of the connecting disc 19 and the main stirring shaft 18 ensures that the main stirring blade 6 can stably rotate with the main stirring shaft 18, and the circumferential uniform spacing of the main paddle 20 enables the main stirring blade 6 to uniformly apply force to the glue in the central region during rotation, fully stirring the glue and improving the uniformity of stirring to guarantee the quality of the glue.

[0038] In a preferred embodiment, as shown in Figure 4 The main paddle 20 is inclinedly arranged on the connecting disc 19. The inclined arrangement of the main paddle 20 can change the force direction of the glue during stirring, compared with the conventional vertical arrangement, it can make the glue form a more complex flow trajectory in the central region of the tank body 1, so that the glue can not only be stirred in the horizontal direction, but also produce good overturning effect in the vertical direction, so that the glue at different depths and different positions can be more fully mixed, effectively improving the uniformity of stirring. Through the inclined arrangement of the main paddle 20, the glue can form a spiral upward or downward flow state in the tank body 1, which helps to break the stratification, local static and other fluid states that are not conducive to uniform stirring of the glue, so that the components of the glue can be better mixed together.

[0039] In a preferred embodiment, as shown in Figure 5As shown, the auxiliary stirring blade 14 comprises a connecting sleeve 21, a connecting rod 23 and an auxiliary paddle; wherein the connecting sleeve 21 is fixedly connected with the auxiliary stirring shaft 13, the connecting rod 23 is fixedly connected with the connecting sleeve 21 and is uniformly spaced in the circumferential direction of the connecting sleeve 21, and the auxiliary paddle 22 is fixedly connected on the connecting rod 23. The connecting rod 23 is uniformly spaced in the circumferential direction of the connecting sleeve 21, and the auxiliary paddle is fixedly connected on the connecting rod 23. This structural design makes the auxiliary stirring blade 14, when rotating, can exert uniform and comprehensive force on the glue outside the tank body 1, avoid the situation that local stirring is not in place, effectively improve the stirring uniformity of the glue in the tank body 1, ensure that the components of the glue are fully mixed, and ensure the quality of the glue.

[0040] In a preferred embodiment, as shown in Figure 6 The bottom side of the main stirring shaft 18 is provided with a pushing blade 24, which is inclined. The pushing blade 24 needs to be ensured to be able to push the glue upwards during stirring when installed. Through this design, the glue in the tank body 1 flows more fully during stirring, improving the stirring effect and ensuring the uniformity of the glue stirring.

[0041] In a preferred embodiment, the inclination angles of the main paddles 20 in the same axial direction are different, for example, the inclination angle of the top main paddle 20 is 45 degrees, the inclination angle of the main paddle 20 in the next layer is 43 degrees, and the inclination angle of the main paddle 20 in the next layer is 40 degrees. Through this design, the main stirring shaft 18 can generate turbulence when rotating, so that the glue in the tank body 1 is mixed more uniformly.

[0042] Further optimization, the surface of the main paddle 20 is provided with a plurality of through holes. They are uniformly distributed on the surface of the main paddle 20, some are circular, some may be elliptical, and others may be various suitable shapes such as polygons, and the hole diameters are also different, the small ones may be only a few millimeters, and the large ones can reach dozens of millimeters. Through these cleverly arranged through holes, when the main paddle 20 stirs the glue, a part of the glue passes through these through holes during flowing through the main paddle 20, thereby changing the original flow path of the glue, further enhancing the turbulence effect, making the mixing of the glue more sufficient and delicate, and maximizing the uniformity of the glue mixing.
