[0002] Adhesives, also known as adhesives, are primarily used to firmly connect one object to another. Adhesives are widely used, with common examples including white latex, glass glue, and UV adhesive. Many adhesives require a mixer during production, ensuring the ingredients are thoroughly mixed and reacted.

[0003] Common mixers typically use a barrel to hold adhesive raw materials, then use a motor to drive a stirring element to rotate within the barrel, thereby stirring the adhesive raw materials within the barrel. Chinese utility model patent publication number CN214915459U provides an adhesive mixer. In this utility model, a stirring motor drives a stirrer to rotate, thereby stirring the raw materials in the barrel. Furthermore, a lifting motor drives a screw nut mechanism to move the barrel up and down, thereby changing the position of the stirrer within the barrel and ensuring a good stirring effect at different positions within the barrel.

[0004] However, the shortcoming of this utility model is that there is a gap between the traditional agitator and the inner wall of the mixing barrel. In particular, in this solution, if the agitator contacts the inner wall of the barrel, there is a risk of collision when the agitator enters the barrel. Therefore, the agitator's stirring effect on the raw materials near the inner wall of the barrel is still not as good as the stirring effect within the agitator's reach, especially for adhesives with higher viscosity. Utility Model Content

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-4 The utility model discloses an adhesive barrel mixer, comprising a frame 1, which is a square frame structure. A mixing barrel 2 is arranged on the inner side of the frame 1. The mixing barrel 2 is a straight cylindrical structure with an open top. A discharge pipe 5 is connected to the bottom of the mixing barrel 2. A valve is installed on the discharge pipe 5. A stirrer 4 is installed above the mixing barrel 2. The stirrer 4 rotates at a fixed position. By raising or lowering the mixing barrel 2, the stirrer 4 stirs the raw materials in the mixing barrel 2. The raw materials are mainly liquid base materials.

[0028] The mixing barrel 2 is connected to the vertically mounted lead screw 6 by transmission. Specifically, bearings are mounted on both ends of the lead screw 6. The bearings are fixedly mounted on the frame 1. The lead screw 6 is rotatably mounted on the frame 1 through the bearings.

[0029] One end of the top of the screw 6 is connected to the working end of the lifting motor 8. Specifically, a belt drive 9 is installed between the screw 6 and the working end of the lifting motor 8. The belt drive 9 includes a belt and two pulleys. The two pulleys are respectively installed at the working end of the lifting motor 8 and the top end of the screw 6. The two pulleys are connected by a belt. A screw nut 7 is mounted on the screw 6. A connecting block is fixedly installed on the screw nut 7. When the lifting motor 8 is started, the screw 6 is driven to rotate through the belt drive 9, and the mixing barrel 2 is further driven to rise or fall.

[0030] A guide rail 3 is installed in the vertical direction on the side of the mixing barrel 2 away from the screw 6. The guide rail 3 is parallel to the screw 6 and is fixedly mounted on the frame 1. A slider is mounted on the guide rail 3. Both ends of the mixing barrel 2 are respectively connected to hanging ears, and the mixing barrel 2 is connected to the connecting block and the slider through the hanging ears.

[0031] The agitator 4 includes a stirring shaft 12, on which a stirring crossbar 14 is fixedly mounted. The ends of both sides of the stirring crossbar 14 are machined with slide grooves along the horizontal axis direction. The slide groove is a through groove structure with left and right ends open. A slide rod 20 is slidably mounted in the slide groove. A stopper groove 17 is connected to the side of the slide groove close to the center of the agitator 4. A stopper 18 is mounted in the stopper groove 17. The size of the stopper 18 is larger than the radial size of the slide groove. The stopper 18 prevents the slide rod 20 from escaping from the slide groove.

[0032] One end of the slide bar 20 is connected to the stopper 18, and the other end is connected to the extension bar 21. The slide bar 20 is provided with a spring 19, which is located between the stopper 18 and the chute. The distance between the stopper 18 and the chute is greater than the minimum distance between the extension bar 21 and the inner wall of the mixing barrel 2.

[0033] The elastic force of the spring 19 is smaller than the centrifugal force when the extension rod 21 rotates with the stirring cross bar 14. When the stirrer 4 starts to rotate, the extension rod 21 drives the slide bar 20 and the stopper 18 to extend in the centrifugal direction under the action of the centrifugal force. At this time, the stopper 18 compresses the spring 19, and the end of the extension rod 21 rests on the inner wall of the mixing barrel 2 and rotates synchronously with the stirring cross bar 14.

[0034] When the agitator 4 stops, the stopper 18, the slide bar 20, and the extension rod 21 are reset under the elastic action of the spring 19, and the end of the extension rod 21 away from the stirring cross bar 14 is away from the inner wall of the mixing barrel 2. The mixing barrel 2 can be raised or lowered normally, and the stirring cross bar 14 and the extension rod 21 will not contact the mixing barrel 2, thereby avoiding the risk of collision.

[0035] Here, the extension rod 21 is mainly made of wear-resistant materials, and can be made of rigid materials such as high-strength metals, plastics, etc., or elastic materials such as rubber with high wear resistance, spring sheets, etc., according to actual manufacturing costs and usage effects.

[0036] The stopper 18 is a permanent magnet. An electromagnet 16 is installed on the side of the stopper 18 away from the slide bar 20. The stopper 18 and the electromagnet 16 repel each other. When the electromagnet 16 is activated, the electromagnet 16 and the permanent magnet repel each other, pushing the stopper 18, the slide bar 20 and the extension rod 21 outward and against the inner wall of the mixing barrel 2, thereby stirring the adhesive raw material near the inner wall of the mixing barrel 2.

[0037] Under given conditions, the centrifugal force of the extension rod 21 is proportional to the square of the rotation speed of the stirrer 4. However, in actual production, the rotation speed of the stirrer 4 is inversely proportional to the viscosity of the raw material. That is, the higher the viscosity of the raw material, the lower the rotation speed of the stirrer 4 during stirring. Raw materials with high viscosity have more obvious resistance to the extension rod 21. However, raw materials with higher viscosity require more thorough stirring. Therefore, the extension rod 21 is extended outward only by centrifugal force, which is mainly suitable for stirring raw materials with low viscosity.

[0038] After the electromagnet 16 is added, the extension of the extension rod 21 is mainly driven by the magnetic force of mutual repulsion between the electromagnet 16 and the permanent magnet. Even at low speed and when the material has a large resistance to the extension of the extension rod 21, the electromagnet 16 can easily push the permanent magnet.

[0039] Furthermore, by changing the current intensity of the electromagnet 16, the magnetic force of the electromagnet 16 can be adjusted, thereby adjusting the repulsive force between the electromagnet 16 and the permanent magnet, and further adjusting the pressure generated by the extension rod 21 against the inner wall of the mixing barrel 2. By reducing the pressure of the extension rod 21 against the mixing barrel 2, the friction between the two is reduced, thereby reducing wear.

[0040] A first wire groove 13 is machined inside the stirring shaft 12, and a second wire groove 15 is machined inside the stirring cross bar 14. The first wire groove 13 is connected to the second wire groove 15. The electromagnet 16 is connected to the external power supply and the controller through a wire. The wire is located in the first wire groove 13 and the second wire groove 15, so that the electromagnet 16 remains energized during the rotation of the stirrer 4.

[0041] A stirring motor 10 is installed on the top of the stirring shaft 12, and the stirring motor 10 is installed on the frame 1 through a motor base. The stirring motor 10 includes an output shaft 22, and the output shaft 22 is connected to the stirring shaft 12 through a transmission box 11, and the transmission box 11 is installed on the frame 1. Figure 1 and 4 As shown, the transmission box 11 is mainly used to transmit power and access power from the outside;

[0042] Specifically, a conductive slip ring 26 is installed below the output shaft 22. The conductive slip ring 26 includes a rotor 24 and a stator 25. The stator 25 is fixedly installed in the transmission case 11. The rotor 24 passes through the stator 25. The output shaft 22 is connected to the top of the rotor 24 through a first coupling 23.

[0043] The stirring shaft 12 is disposed below the conductive slip ring 26. The bottom of the rotor 24 is connected to the top of the stirring shaft 12 via a second coupling 28. The wires in the first wire slot 13 are connected to the terminals on the rotor 24, and the terminals on the stator 25 are connected to an external power supply and controller, thereby ensuring that the electromagnet 16 remains energized during rotation.

[0044] A rotating shaft seat 27 is installed below the second coupling 28. The rotating shaft seat 27 is sleeved on the stirring shaft 12. A rotating shaft bearing is installed inside the rotating shaft seat 27. The rotating shaft bearing and the stirring shaft 12 have an interference fit. The rotating shaft seat 27 is fixedly installed in the transmission box 11. In this way, the rotating shaft seat 27 mainly bears axial force, while the first coupling 23, the conductive slip ring 26, and the second coupling 28 mainly bear axial torsion, which meets the use requirements.

[0045] In fact, a reduction gearbox needs to be installed between the output shaft 22 and the first coupling 23. The reduction gearbox is a mature existing technology and does not need to be described in detail here.

[0046] A solvent barrel 29 and an electric sprayer 30 connected to the solvent barrel 29 are installed on one side of the frame 1. The electric sprayer 30 is equipped with a small liquid pump. The solvent barrel 29 is filled with a disintegrating agent. The nozzle of the electric sprayer 30 is facing the agitator 4. The electric sprayer 30 is started regularly or when the type of adhesive is changed to spray the disintegrating agent on the agitator 4 and the inside of the mixing barrel 2 to clean the adhesive remaining on the outer surface of the agitator 4 and the inner surface of the mixing barrel 2.

[0047] Working Principle: When in use, the raw materials for producing the adhesive are poured into the mixing barrel 2, and then the lifting motor 8 is started to drive the screw 6 to rotate, further driving the mixing barrel 2 to rise. When the agitator 4 is located in the mixing barrel 2, the stirring motor 10 and the electromagnet 16 are started. The stirring motor 10 drives the agitator 4 to rotate, stirring the raw materials. At the same time, the electromagnet 16 pushes the extension rod 21 against the inner wall of the mixing barrel 2, thereby stirring the raw materials near the inner wall of the mixing barrel 2;

[0048] After the stirring is completed, the stirring motor 10 and the electromagnet 16 are turned off, the extension rod 21 is reset, the lifting motor 8 is controlled to drive the stirring barrel 2 to lower, the discharge pipe 5 is opened to discharge the stirred raw materials, and the raw materials are poured in next time, or the electric sprayer 30 is started to clean the stirrer 4 and the stirring barrel 2 (the stirring barrel 2 is raised).
