[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0025] Embodiment 1:

[0026] As Figure 1 - Figure 5As shown in the figure, a handheld automatic coupling agent heating and pushing device includes a housing 1. A handle 2 is fixedly connected to the left side of the housing 1. A flip cover 3 is arranged on the upper side of the housing 1. A hook 4 is fixedly connected to the lower side of the flip cover 3. A discharge port 5 is opened on the lower side of the housing 1. A material extrusion unit 7 is arranged inside the housing 1. A battery 6 is arranged inside the housing 1 and below the steering gear 701. The battery 6 provides power for the steering gear 701, facilitating the uniform discharge of the coupling agent and quantitative discharge. The hook 4 on the flip cover 3 is convenient for hanging the housing 1 at the required position, and the handle 2 is used to facilitate the staff to hold the housing 1, making the device more convenient.

[0027] The material extrusion unit 7 includes a steering gear 701. The steering gear 701 is arranged inside the housing 1. An installation frame 702 is arranged between the steering gear 701 and the housing 1. Output shafts 703 are fixedly connected to both the front and rear sides of the steering gear 701. Two connecting plates 704 are fixedly connected to the outer sides of the output shafts 703 on both the front and rear sides. A pushing roller 705 is fixedly connected between the connecting plates 704 on both the front and rear sides. A pushing plate 707 is arranged inside the housing 1. The pushing plate 707 is arranged in a V-shaped structure. The pushing plate 707 includes a fixed plate 70701, a moving plate 70702 and a rotating shaft 70703. The rotating shaft 70703 is rotatably connected inside the housing 1 and above the discharge port 5. The fixed plate 70701 and the moving plate 70702 are both fixedly connected to the outer side of the rotating shaft 70703. The fixed plate 70701 is fixedly connected to the moving plate 70702. The moving plate 70702 is located between the two pushing rollers 705. When discharging, the steering gear 701 is controlled to start. The steering gear 701 drives the output shafts 703 on both the front and rear sides to rotate. The output shafts 703 on both the front and rear sides drive the connecting plates 704 to rotate. The connecting plates 704 drive the pushing rollers 705 to rotate. The pushing rollers 705 perform an Archimedean spiral trajectory. When the lower pushing roller 705 rotates counterclockwise, it drives the moving plate 70702 and the fixed plate 70701 to rotate. When the upper pushing roller 705 rotates clockwise, it drives the moving plate 70702 and the fixed plate 70701 to rotate in the opposite direction, causing the pushing plate 707 to rotate repeatedly, generating a thrust force to uniformly discharge the coupling agent inside, and by controlling the swing angle and time of the steering gear 701, it is convenient to control the amount of the extruded coupling agent, reducing the labor intensity of the staff. On the pushing plate 707, the moving plate 70702 and the fixed plate 70701 are used. The fixed plate 70701 is pushed by the acting force to extrude the material. The bottom of the moving plate 70702 is fixed by the rotating shaft 70703. The distance from the stressed part to the center of the shaft is getting farther and farther. According to the lever principle, the larger the force arm, the smaller the acting force, and the greater the force as the material decreases, ensuring that the material is finally pushed out completely.

[0028] A heating rod 706 is provided inside the inner side of the pushing roller 705. The heating rod 706 is made of a silicone heating sheet, and its structure consists of a silicone heating body, an aluminum layer, a copper layer, a silver layer, a wire, etc. When the heating sheet is powered on, the current enters the copper layer from the wire, and then enters the silicone heating body through the silver layer, forming a magnetic field and exciting the polarized molecules inside the silicone heating body. These polarized molecules will generate friction and collision, thereby generating heat energy to heat the heating body and heat the coupling agent.

[0029] Embodiment 2:

[0030] On the basis of Embodiment 1, an airbag is provided between the left outer wall of the moving plate 70702 and the inner wall of the outer shell 1. The output port of the airbag is located inside the outer shell 1. The input end of the airbag passes through the outside of the outer shell 1. Check valves are provided at both the output port and the input port of the airbag. When the moving plate 70702 swings repeatedly, the airbag is squeezed. When the airbag is squeezed, the air in the airbag is discharged into the outer shell 1. When the airbag is not squeezed, external air enters the airbag. By repeating the above process, external air enters the outer shell 1, increasing the air pressure in the outer shell 1, and enabling the gas to push the coupling agent, thereby increasing the discharging speed of the coupling agent.

[0031] Working principle: During use, first open the flip cover 3, pour the coupling agent into the inside of the outer shell 1. Then the staff holds the outer shell 1 through the grip 2 and controls the servo 701 to start. The servo 701 drives the output shaft 703 to rotate. Under the action of the connecting plate 704, the pushing rollers 705 on both sides are controlled to rotate. The pushing rollers 705 swing repeatedly, causing the pushing rollers 705 to drive the V-shaped pushing plate 707 to swing repeatedly, so that the pushing plate 707 evenly extrudes the coupling agent through the discharge port 5. By controlling the swing angle and time of the servo 701, the extrusion amount is controlled, reducing the workload of the staff.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
