Description

Technical Field

[0001] This utility model relates to the field of urea-formaldehyde resin adhesive production technology, specifically a feeding mechanism for preparing urea-formaldehyde resin adhesive. Background Technology

[0002] The large and growing market for urea-formaldehyde resin, particularly in the construction and furniture sectors, has spurred manufacturers to upgrade their equipment. In the process of preparing urea-formaldehyde resin, the feeding mechanism is a crucial piece of equipment, responsible for conveying raw materials such as urea, formaldehyde, and catalysts into the reaction vessel.

[0003] Because the raw materials need to be thoroughly mixed in the reactor and undergo polymerization at a certain temperature, the production time for each batch of urea-formaldehyde resin is relatively long. Most of the production time is spent mixing several raw materials, which limits production speed and reduces efficiency. To address these issues, this invention provides a feeding mechanism for preparing urea-formaldehyde resin adhesive. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a feeding mechanism for preparing urea-formaldehyde resin adhesive. This solves the problem that because the raw materials need to be fully mixed in the reactor and undergo polymerization at a certain temperature, the production of each batch of urea-formaldehyde resin is relatively long, with most of the production time spent stirring and mixing several raw materials, which prevents the production speed from being increased and reduces production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for preparing urea-formaldehyde resin adhesive, comprising a premixed storage feeding tank, a solid feeding hopper fixedly connected to the top of the premixed storage feeding tank, a grinding disc fixedly connected inside the solid feeding hopper, and an accelerating mixing component rotatably connected inside the premixed storage feeding tank and the solid feeding hopper. The accelerating mixing component includes a rotating conical grinding disc, a spreading slant, and mixing blades. The rotating conical grinding disc is rotatably connected inside the grinding disc and is used to crush large solid particles. The spreading slant is fixedly connected to the bottom of the rotating conical grinding disc and is used to evenly spread solid particles. The mixing blades are used to premix the liquid and solid.

[0006] Preferably, the premixed storage feed tank is provided with a liquid feed port and a premixed liquid feed port. The liquid feed port is fixedly connected to one side of the premixed storage feed tank and is used to connect to the liquid raw material conveying pipe. The premixed liquid feed port is located at the bottom of the premixed storage feed tank and is equipped with a feed valve, which is used to control the flow rate entering the reactor.

[0007] Preferably, the premixed storage feed tank is further provided with a catalyst storage device, which is fixedly connected to the other side of the premixed storage feed tank. A catalyst nozzle is fixedly connected to the output end of the catalyst storage device, and the catalyst nozzle is used to evenly sprinkle the catalyst into the premixed storage feed tank.

[0008] Preferably, the solid feed hopper further includes a servo motor and a solid feed inlet. The servo motor is fixedly connected to the top of the solid feed hopper and is used to drive the rotation of the rotating conical grinding disc, the feeding slant disc, and the mixing blades. The solid feed inlet is used to convey solid raw material particles.

[0009] Preferably, a bottom support plate is fixedly connected to the bottom of the solid feed hopper, the grinding disc is fixedly connected to the bottom support plate, a cross-shaped fixing block is fixedly connected inside the bottom support plate, and the rotating conical grinding disc and the feeding slant disc are both rotatably connected to the cross-shaped fixing block.

[0010] Preferably, the accelerated mixing component further includes a fixed rotating shaft and a fixed shaft column. The fixed rotating shaft is fixedly connected to the power output end of the servo motor, the rotating conical grinding disc is fixedly connected to the bottom end of the fixed rotating shaft, one end of the fixed shaft column is fixedly connected to the bottom end of the feeding swash plate, and the other end of the fixed shaft column is fixedly connected to the mixing blade.

[0011] This utility model discloses a feeding mechanism for preparing urea-formaldehyde resin adhesive, which has the following beneficial effects: This feeding mechanism for preparing urea-formaldehyde resin adhesive, by setting a grinding disc and a rotating conical grinding disc that can grind large solid particles, makes the volume of the fed solid particles smaller, making the mixing and dissolution faster and improving the mixing speed. In addition, the feeding slant plate can more evenly sprinkle solid material into liquid raw materials, and the mixing and stirring blades further mix the solid and liquid raw materials, saving the mixing time of the mixed raw materials in the reaction vessel and improving the production and processing speed.
