[0018] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0019] like Figure 1-Figure 5 As shown, a reaction kettle for preparing an adhesive proposed by the present invention comprises a kettle body 11, a kettle cover 12 and a kettle bottom 13 are respectively formed at the upper and lower parts of the kettle body 11, a feeding end seat 14 for feeding is installed at the upper part of the kettle cover 12, and a discharging end seat 15 for discharging is installed at the lower part of the kettle bottom 13, the kettle body 11 corresponds to the mixing part, the kettle cover 12 corresponds to the feeding part, and the kettle bottom 13 corresponds to the discharging part, and the ingredients of the adhesive are transported into the reaction kettle for preparation; The driving mechanism includes a driving device 21 installed on the upper part of the kettle cover 12, and the output end of the driving device 21 is connected to a stirring shaft 23 penetrating into the inner cavity of the kettle body 11; The stirring mechanism includes stirring frames 31 which are sleeved on the outer periphery of the stirring shaft 23 at intervals, and two adjacent stirring frames 31 are connected by inclined inclined rods 32, and stirring ring pieces 33 are sleeved on the outer sides of the inclined rods 32 at intervals; The heating mechanism includes a pipe guide groove 44 opened on the stirring frame 31 . A heating pipe 42 is drawn through the pipe guide groove 44 . The lower part of the heating pipe 42 is connected through a curved pipe 43 , and the upper part is connected to the heating device 41 .

[0020] It should be noted that coaxial shaft seats 22 are installed on the opposite sides of the kettle cover 12 and the kettle bottom 13, and the stirring shaft 23 rotates along the inner walls of the two shaft seats 22. The driving device 21 drives the stirring shaft 23 to rotate in the center of the shaft seat 22 to provide stirring power.

[0021] In this embodiment, the stirring mechanism of the reactor base is improved, and the ordinary stirring frame 31 structure is improved into a hollow "cross" structure. An angle is left at the connection between the stirring frame 31 and the inclined rod 32, and stirring in different angles and directions is performed through the cooperation of the inclined rod 32 and the stirring ring 33. The heating mechanism is arranged on the stirring frame 31. On the one hand, it is used to heat and mix the adhesive ingredients, and on the other hand, it can act as a stirring structure to assist stirring, thereby realizing three-dimensional stirring and improving the adhesive preparation effect.

[0022] It can be understood that the combination of the stirring ring 33 and the inclined rod 32 is a rotating structure as a whole. The stirring ring 33 is sleeved on the outer periphery of the inclined rod 32, and rotates when it comes into contact with the adhesive ingredient. During the rotation of the stirring ring 33, the adhesive ingredient is rotated secondary, which solves the laminar mixing problem of high-viscosity materials and effectively improves the stirring and mixing effect.

[0023] In order to facilitate the flow of adhesive ingredients, further, a plurality of heating tubes 42 are installed between adjacent stirring racks 31 , and a gap is left between two adjacent heating tubes 42 .

[0024] like Figure 2-Figure 4 As shown, the scraper mechanism includes a ring rail 51 arranged in the kettle body 11, an electric slide 52 capable of circumferential displacement is installed in the ring rail 51, a suspension 53 is installed on the electric slide 52, a suspension plate 55 with adjustable spacing is arranged below the suspension 53, and a scraper 56 attached to the inner wall of the kettle body 11 is connected to the far end of the suspension plate 55; The material moving mechanism comprises a gear assembly 61 arranged on the suspension plate 55 , one end of the gear assembly 61 is connected to a motor 62 , and the other end is connected to a screw shaft 63 , and an outer wall of the screw shaft 63 is sleeved with a spiral auger 64 .

[0025] In one embodiment, since a large amount of adhesive ingredients are attached to the inner wall of the reactor, the existing stirring mechanism is difficult to stir, resulting in the problem that the adhesives produced before and after are not fully mixed. A scraper mechanism is provided, and the electric slide 52 can slide in a circle in the ring rail 51. During the sliding process, the suspension 53, the connecting rod 54 and the suspension plate 55 synchronously make a circular motion. At this time, the scraper 56 scrapes the adhesive ingredients attached to the reactor wall with the circumferential rotation to separate them from the reactor wall. Since the adhesive ingredients separated from the reactor wall are still at a certain distance from the stirring mechanism, the separated adhesive ingredients are transported to the stirring mechanism as much as possible through the material transfer mechanism. The motor 62 drives the gears in the gear assembly 61 to cooperate with the transmission, driving the spiral auger 64 on the screw shaft 63 to rotate, and transporting the adhesive ingredients to the stirring mechanism. After multiple rotation cycles of circular motion, the adhesive ingredients attached to the kettle wall are also fully stirred and mixed, ensuring that the adhesive produced subsequently always meets the process requirements and improves the processing quality.

[0026] like Figure 2 As shown, each group of suspensions 53 and suspension plates 55 are connected by at least two connecting rods 54. The purpose of setting the two connecting rods 54 is to ensure the stability of the suspension plates 55 installed on the suspensions 53. At the same time, because the connecting rod part extends into the adhesive ingredients, the double-rod design effectively improves the resistance effect during the mixing process.

[0027] Among them, because the scraper mechanism is arranged in four groups at equal angles, in order to enable the scraper 56 to fully act on the inner wall of the kettle body 11, connecting rods of different heights are arranged, and the height of the connecting rod 54 increases with the angle. The four connecting rods 54 fully contact the kettle wall at various positions during the circular rotation process, and within one circular rotation cycle, the attached adhesive ingredients are separated and scraped out of the kettle wall once.

[0028] Alternatively, the different height designs of the connecting rod 54 can be replaced by a cylinder structure. The movement of the piston rod at the delivery end of the cylinder can control the spacing and move each scraper 56 to a specified position. Compared with the design of the connecting rod 54, it has the advantage of convenient length control.

[0029] It can be understood that the end of the scraper 56 attached to the inner wall of the kettle body 11 has a gradually thickened "arc-shaped" structure, and the front end of the scraper 56 is designed with a thin blade (close to the kettle wall side) to reduce the initial contact resistance and avoid excessive shear force when the scraper is inserted into the material. The thin blade structure can cut into the interface between the adhesion layer and the kettle wall to reduce the stripping energy consumption; The rear end of the scraper 56 gradually thickens and transitions into an arc shape, which disperses the scraping reaction force through the gradual change of the cross section to prevent the scraper from deforming. The arc-shaped back side guides the scraped material to avoid secondary adhesion; The arc profile makes the scraper and the kettle wall form a line contact instead of a point contact, reducing the wear on the kettle wall. The gradual thickness design avoids stress concentration and improves the fatigue life of the scraper 56; A gap is left between the scraper 56 and the gear assembly 61, and the gap forms a secondary mixing channel. The scraped materials flow back to the stirring core area of ​​the stirring mechanism through the gap, thereby enhancing convection mixing.

[0030] As a driving example of the material moving mechanism: the gear assembly 61 has a built-in driving gear and a rotating gear, the driving gear is connected to the output end of the motor 62, and the rotating gear is connected to the screw shaft 63; the power for the rotation of the driving gear comes from the output end of the motor 62, and during the rotation of the driving gear, the rotating gear meshes with it to drive the spiral auger 64 connected to the screw shaft 63 to rotate, at this time, the material scraped off by the scraper 56 and the surrounding material are transported to the mixing core area through the spiral auger 64, effectively solving the problem of sufficient mixing of the adhesive ingredients only in the mixing core area.

[0031] like Figure 6 As shown, the heat-insulating mechanism includes a heat-insulating sleeve 71 sleeved on the outside of the kettle body 11 , and the heat-insulating sleeve 71 is filled with a heat-insulating filler 72 .

[0032] In one embodiment, the thermal insulation bushing 71 is stacked on the kettle body 11, and the inner cavity of the thermal insulation bushing 71 is a hollow structure, which is used to fill the thermal insulation filler 72 with a thermal insulation effect. The purpose is to prevent the heat in the kettle body 11 from leaking out, prevent the internal adhesive from condensing due to temperature drop, and ensure that the adhesive is in a mixed flow state during mixing.

[0033] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
