Description

Technical Field

[0001] This utility model relates to the field of phenolic resin adhesive production, and in particular to a raw material pre-mixing device for phenolic resin adhesive production. Background Technology

[0002] Phenolic resin, originally a colorless or yellowish-brown transparent substance, is a general term for resins formed by phenols and aldehydes under the action of a catalyst. It is used in many industrial fields and remains an important synthetic polymer material. Phenolic resin adhesives produced from it have advantages such as high bonding strength, water resistance, heat resistance, wear resistance and good chemical stability.

[0003] Phenolic resin adhesive, as an important industrial adhesive, is widely used in many fields such as wood processing and construction. Its production quality largely depends on the uniformity of raw material mixing. In traditional production processes, the raw material pre-mixing stage often has many problems. Generally, simple open containers and ordinary stirring paddles are used for mixing. This method is not only inefficient, but also makes it difficult to ensure that different raw materials are fully and uniformly mixed in a short time. The raw materials are prone to dead zones in the mixing container, and some raw materials cannot be fully mixed, resulting in inconsistent quality of the final product. This, in turn, affects the performance stability and quality consistency of the phenolic resin adhesive. To address these issues, we propose a raw material pre-mixing device for phenolic resin adhesive production. Utility Model Content

[0004] The purpose of this invention is to provide a raw material pre-mixing device for the production of phenolic resin adhesives, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pre-mixing device for raw materials in the production of phenolic resin adhesive includes a processing cylindrical tank. A support frame is fixedly connected to the upper surface of the processing cylindrical tank. A rotary motor is fixedly mounted on the upper surface of the support frame. A circular shaft is fixedly connected to the output end of the rotary motor. Multiple stirring blades are fixedly connected to the outer surface of the circular shaft. A fixed circular rail is fixedly connected to the upper surface of the processing cylindrical tank. Multiple sliding blocks are slidably connected inside the fixed circular rail. A circular gear ring is fixedly connected to the outer surface of the multiple sliding blocks. Multiple vertical stirring blades are fixedly connected to the bottom surface of the circular gear ring. A support frame is fixedly connected to the upper surface of the processing cylindrical tank. A drive motor is fixedly connected to the inner wall of the support frame. A drive gear is fixedly connected to the output end of the drive motor and meshes with the circular gear ring. A circular opening is provided on the upper surface of the processing cylindrical tank.

[0007] In a further embodiment, the bottom of the processing cylinder is funnel-shaped, and a discharge pipe is fixedly connected to the bottom surface of the processing cylinder. An electric valve is provided on the outer surface of the discharge pipe.

[0008] In a further embodiment, a feed hopper is provided on the upper part of the outer surface of the processing cylinder, and multiple supporting diagonal rods are fixedly connected to the bottom surface of the processing cylinder.

[0009] In a further embodiment, two transmission rods are fixedly connected to the bottom end of the circular shaft, and each transmission rod is fixedly connected to a slanted scraper at its bottom end.

[0010] In a further embodiment, an annular slide is fixedly connected to the inner wall of the processing cylinder, and two sliding rods are slidably connected inside the annular slide, with one end of each sliding rod fixedly connected to the outer surface of the circular shaft.

[0011] In a further embodiment, two support rods are fixedly connected to the upper surface of the support frame, and the top end of each support rod is fixedly connected to the outer surface of the rotary motor. The inner wall of the processing cylinder is provided with a corrosion-resistant inner liner, which can be made of polyurethane acid and alkali resistant material.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device uses a rotary motor to drive a circular shaft to rotate, causing multiple agitator blades fixed on the shaft to stir the raw materials in the processing tank, thus agitating the material in the center. Simultaneously, the drive motor drives a drive gear to rotate, causing a meshing circular gear ring to rotate along a fixed circular track. This, in turn, causes multiple vertical agitator blades on the bottom of the circular gear ring to stir the raw materials on the sides. This stirring method allows the raw materials to flow in a multi-dimensional manner within the tank, avoiding dead zones and ensuring that all raw material components are fully and evenly mixed. This guarantees the quality of the pre-mixing of the phenolic resin adhesive raw materials and lays the foundation for the subsequent production of stable and high-quality phenolic resin adhesive.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4In this utility model, a raw material pre-mixing device for phenolic resin adhesive production includes a processing cylindrical tank 1. A support frame 6 is fixedly connected to the upper surface of the processing cylindrical tank 1. A rotary motor 7 is fixedly installed on the upper surface of the support frame 6. A circular shaft 17 is fixedly connected to the output end of the rotary motor 7. Multiple stirring blades 18 are fixedly connected to the outer surface of the circular shaft 17. A fixed circular rail 11 is fixedly connected to the upper surface of the processing cylindrical tank 1. Multiple sliding blocks 12 are slidably connected inside the fixed circular rail 11. A circular gear ring 13 is fixedly connected to the outer surface of the multiple sliding blocks 12. Multiple vertical stirring blades 14 are fixedly connected to the bottom surface of the circular gear ring 13. A support frame 8 is fixedly connected to the upper surface of the processing cylindrical tank 1. A drive motor 9 is fixedly connected to the inner wall of the support frame 8. A drive gear 10 is fixedly connected to the output end of the drive motor 9, and the drive gear 10 and the circular gear ring 13 are connected to each other. The rings 13 mesh with each other, and a circular opening 16 is provided on the upper surface of the processing tank 1. The circular opening 16 does not affect the rotation of the vertical stirring paddle 14, ensuring the feasibility of rotation. The circular shaft 17 is driven to rotate by the rotary motor 7, so that multiple stirring blades 18 fixed on the circular shaft 17 stir the raw materials in the processing tank 1, realizing the turning of the material in the center. At the same time, the drive motor 9 drives the drive gear 10 to rotate, which drives the circular gear ring 13 meshing with it to rotate along the fixed circular rail 11, thereby causing multiple vertical stirring paddles 14 on the bottom surface of the circular gear ring 13 to stir the raw materials on the side. This stirring method can make the raw materials form a multi-dimensional flow in the tank, avoid the formation of stirring dead corners, effectively meet the multi-faceted needs of raw material pre-stirring in the production process of phenolic resin glue, improve production efficiency and product quality, and ensure the smooth progress of the production process.

[0023] The bottom of the processing tank 1 is funnel-shaped, and a discharge pipe 3 is fixedly connected to the bottom surface of the processing tank 1. An electric valve 4 is installed on the outer surface of the discharge pipe 3, which facilitates the raw materials to gather into the discharge pipe 3 by their own gravity after mixing. The electric valve 4 on the outer surface of the discharge pipe 3 allows the operator to control the timing and flow rate of discharge according to actual needs. A feed hopper 5 is installed on the upper part of the outer surface of the processing tank 1. Multiple support inclined rods 2 are fixedly connected to the bottom surface of the processing tank 1, which facilitates the addition of raw materials to be mixed and makes the device more stable. Two transmission rods 21 are fixedly connected to the bottom end of the circular shaft 17. Each transmission rod 21 is fixedly connected to the bottom end of an inclined scraper 22. When the circular shaft 17 rotates, it can rotate the transmission rods 21 and the inclined scraper 22, which can scrape the raw materials at the bottom of the tank to prevent the raw materials from accumulating at the bottom of the tank and affecting the mixing effect and subsequent discharge.

[0024] The inner wall of the processing tank 1 is fixedly connected to an annular slide rail 19. Two sliding connecting rods 20 are slidably connected inside the annular slide rail 19. One end of each sliding connecting rod 20 is fixedly connected to the outer surface of the circular shaft 17, providing stable support and guidance for the rotation of the circular shaft 17 and improving the stability of the device. Two support rods 23 are fixedly connected to the upper surface of the support frame 6. The top end of each support rod 23 is fixedly connected to the outer surface of the rotary motor 7. The inner wall of the processing tank 1 is provided with a corrosion-resistant inner liner 15, which can be made of polyurethane acid and alkali resistant material, making the operation of the rotary motor 7 more stable and effectively resisting the corrosion of the tank body by the raw materials of phenolic resin glue production, thus extending the service life of the equipment.

[0025] The working principle of this utility model is as follows:

[0026] In use, the raw materials to be mixed are added into the processing tank 1 through the feed hopper 5. The rotary motor 7 is started to rotate the circular shaft 17 and the stirring blade 18. The forward rotation of the circular shaft 17 and the stirring blade 18 can perform preliminary stirring of the raw materials. Then, the drive motor 9 can be started to rotate the drive gear 10. When the drive gear 10 rotates, it can mesh with the circular gear ring 13 and the sliding block 12 to rotate in the fixed circular rail 11. When the circular gear ring 13 rotates in the reverse direction, it can drive multiple vertical stirring blades 14 to stir the raw materials on the side. In this way, the raw materials are stirred in multiple dimensions, so that the raw materials form a multi-dimensional flow in the tank, avoiding the formation of stirring dead zones and promoting the full and uniform mixing of the raw material components.
