Description

Technical Field

[0001] This utility model relates to a stirring device for a reaction vessel used in resin production and processing, and belongs to the technical field of stirring devices. Background Technology

[0002] Resins are a class of high-molecular-weight compounds with good molding properties, typically made from organic chemicals of plant, synthetic, or natural origin. Natural resins, such as rosin, are mainly derived from plant secretions, while synthetic resins are synthesized through chemical reactions; common examples include epoxy resins, polyester resins, and acrylic resins. In resin processing, stirring is a crucial step, primarily used to ensure that the resin and other components (such as curing agents, fillers, and additives) are uniformly mixed. Stirring effectively prevents the raw materials from separating, settling, or unevenly distributing within the resin, ensuring that the final product has consistent physical and chemical properties.

[0003] Authorization announcement number (CN218834172U) discloses a mixing device for resin sand production and processing, including a support plate. The top of the support plate has a groove, and a mixing tank is slidably connected to the bottom of the inner side of the groove. A support frame is fixedly connected to the top of the support plate. A servo motor is provided at the top of the support frame. The output shaft of the servo motor passes through the top of the support frame. A mixing component is threadedly connected to the bottom of the servo motor. A feeding mechanism is provided at the top of the support frame. A control module is installed on the left side of the support frame. With the above structure, when feeding is required, a suction pipe can be placed into the mixing tank through a through hole. Then, the pump is started, and the suction pipe will suck in the raw material in the mixing tank. Then, the pump will extract it from the discharge pipe, thus eliminating the need for manual feeding and avoiding the beneficial effect of material spilling onto the ground during feeding.

[0004] However, the above-mentioned technologies rely on the rotation of the stirring blades in the resin for mixing during resin processing. This usually only produces strong stirring in local areas, which may lead to uneven material distribution. In particular, the added curing agent, filler, or additives may not be fully mixed with the resin, affecting the quality of the final product. Furthermore, existing stirring devices usually rely on the shear force generated by mechanical motion to mix materials, but this method may result in a slower mixing speed, especially when processing viscous resins or resins containing a large amount of solid filler, resulting in low stirring efficiency.

[0005] Therefore, a stirring device for a reaction vessel used in resin production and processing is proposed. Utility Model Content

[0006] In view of this, the present invention provides a stirring device for a reaction vessel in resin production and processing, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0028] Example 1

[0029] like Figure 1-5 As shown, this utility model embodiment provides a stirring device for a reaction vessel used in resin production and processing, including a connecting frame 1 and a stirring tank 2. The stirring tank 2 is located inside the connecting frame 1. A mixing component 3 is provided on the surface of the stirring tank 2. The mixing component 3 includes a sleeve 301, a fixing block 302, a support rod 303, a connecting block 304, a pulley 305, a pressure plate 306, and a spring 307. The sleeve 301 is fixedly installed around the surface of the stirring tank 2. The fixing blocks 302 are located outside the sleeve 301. The connecting blocks 304 are fixedly connected to the left and right sides inside the four fixing blocks 302. The pulley... 305 is movably connected to the inner side of the connecting block 304 via a rotating shaft. Spring 307 is fixedly connected to the inner cavity of the four sleeves 301. Support rod 303 is fixedly connected to the bottom of the four fixing blocks 302. Pressure plate 306 is fixedly installed at the lower end of support rod 303. The bottom of pressure plate 306 is fixedly connected to the upper end of spring 307. A through hole 308 is opened at the top of sleeve 301. Support rod 303 passes through through hole 308 and is connected to pressure plate 306. Servo motor 309 is fixedly installed on the rear side of connecting frame 1. The output end of servo motor 309 is fixedly connected to the rear side of mixing tank 2.

[0030] The mixing component 3 provides uniform material flow and mixing effect, ensuring that the resin can be fully integrated with other components, avoiding local unevenness or sedimentation. During the mixing process, the mixing tank 2 vibrates while rotating. This vibration can effectively break up air bubbles in the resin, improve mixing efficiency, reduce air bubble residue, thereby improving the density and strength of the resin and avoiding the impact of air bubbles on the performance of the final product. In addition, the vibration can also accelerate the dispersion of curing agents and other additives, improve the reaction rate, optimize the resin flowability, and make it easier to process and mold.

[0031] Example 2

[0032] like Figure 1-5 As shown, in one embodiment, a bearing sleeve 4 is fixedly installed on the inner side of the connecting frame 1, and the output end of the servo motor 309 is in contact with the inner side of the bearing sleeve 4. Fixing frames 5 are fixedly installed on both the upper and lower sides of the inner side of the connecting frame 1. An annular connecting frame 6 is fixedly installed on the inner side of the fixing frame 5. An annular groove 7 is opened on the inner side of the annular connecting frame 6. The pulley 305 is in contact with the inner side of the annular groove 7. A fixing bolt 9 is connected to the front side of the mixing box 2, and a valve for controlling the feeding and discharging of materials is installed on the inner side of the fixing bolt 9. Fixing bolts 9 are fixedly installed on all four sides of the bottom of the connecting frame 1. The lower end of the fixing bolt 9 passes through the connecting frame 1 and extends to the bottom of the connecting frame 1.

[0033] By setting the bearing sleeve 4, the wear of the output end during the rotation of the mixing tank 2 driven by the servo motor 309 can be reduced. By setting the fixing bracket 5, the annular connecting bracket 6 can be fixed. By setting the annular connecting bracket 6, the stability of the mixing tank 2 during rotation can be improved. By setting the fixing bolt 9, the connecting bracket 1 can be connected and fixed to the external structure, thereby improving the overall stability.

[0034] In operation, this invention works as follows: First, the feed pipe 8 is rotated to the top of the mixing tank 2. After the resin and mixture are placed into the mixing tank 2 through the feed pipe 8, the mixing tank 2 is rotated by the servo motor 309, causing the materials to tumble and mix inside the mixing tank 2. Simultaneously, the rotation of the mixing tank 2 causes the sleeves 301 connected around its surface to rotate. During this rotation, the sleeves 301 drive the fixing block 302, connecting block 304, and pulley 305 to rotate circumferentially, causing the pulley 305 to roll inside the annular groove 7, thus improving the mixing tank 2's rotation efficiency. To ensure stability, when the fixed block 302 rotates, it will vibrate due to the tumbling of the material inside the mixing tank 2. During the vibration, the support rod 303 and the connecting block 304 will shift outward. As the connecting block 304 moves, it will compress the spring 307, causing the spring 307 to deform. When the spring 307 loses the external compression, it will rebound through its own tension, thereby causing the mixing tank 2 to vibrate while rotating, further improving the mixing effect. After mixing is completed, the mixing tank 2 can be rotated to adjust the material pipe 8 to the bottom for discharge.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
