Description

Technical Field

[0001] This utility model relates to the field of phenolic resin synthesis technology, specifically to an automatic feeding device for phenolic resin synthesis. Background Technology

[0002] Phenolic resin, as a high-performance thermosetting resin, possesses characteristics such as high temperature resistance, ablation resistance, good insulation, and high mechanical strength, and is widely used in electronics, building materials, aerospace, and automobile manufacturing. Its synthesis mainly uses phenol and formaldehyde as raw materials, which undergo a condensation reaction under the action of a catalyst. The precision, uniformity, and temperature stability of the raw material feed directly affect the molecular weight distribution, curing performance, and final product quality of the resin.

[0003] Chinese patent CN214553358U discloses an automatic feeding system for phenolic resin synthesis, including a conveying device and several supporting devices installed at the bottom of the conveying device. Several holding devices are mounted on the conveying device, each holding device including a holding box. A first motor is installed inside the holding box, and a rotating rod is coaxially connected to the side of the first motor. Several stirring blades are sleeved on the side of the rotating rod. This device, through the holding devices, places the phenolic resin material into the holding box during feeding. The motor drives the rotating rod, which in turn drives the stirring blades to stir the material, preventing the liquid material from solidifying into lumps during feeding, thus ensuring proper mixing. However, the following drawbacks still exist: The material is stirred by rotating the rotating rod driven by the motor. The motor rotates with the belt, and each container is equipped with a motor, which is costly. In addition, the motor cable needs to move with the belt to provide power, so an additional sliding power supply structure needs to be designed, which makes the structure more complicated.

[0005] The specific technical solution is as follows: An automatic feeding device for phenolic resin synthesis includes: two supports, multiple drive rollers rotatably connected between the two supports, support legs symmetrically arranged at the bottom of the supports, and a phenolic resin synthesis raw material conveyor belt sleeved between the drive rollers.

[0006] In the above-mentioned automatic feeding device for phenolic resin synthesis, a drive motor is fixedly installed on one side of the bracket, and the output shaft end of the drive motor is fixedly connected to one end of a transmission roller.

[0007] In the above-mentioned automatic feeding device for phenolic resin synthesis, the stirring blades are evenly distributed on the surface of the rotating rod, and the inner wall of the conveying box, the rotating rod, and the surface of the stirring blades are all provided with an anti-corrosion layer.

[0008] The above-mentioned automatic feeding device for phenolic resin synthesis includes a cooling mechanism on the support frame. The cooling mechanism includes a fixed frame that is fixedly connected to the surface of the support frame. Air outlets are evenly distributed at the bottom of the fixed frame and are oriented towards the transmission roller.

[0010] In the aforementioned automatic feeding device for phenolic resin synthesis, a rotating shaft is fixedly connected to one side of the fan blade, a driven pulley is fixedly connected to one end of the rotating shaft, and a driving pulley is fixedly connected to one end of the transmission roller.

[0022] Example This embodiment provides an automatic feeding device for phenolic resin synthesis, such as... Figure 1 - Figure 5 As shown, it includes: two supports 100, with multiple drive rollers 200 rotatably connected between the two supports 100, drive rollers 200, support legs 110 symmetrically arranged at the bottom of the supports 100, and a phenolic resin synthetic raw material conveyor belt 300 sleeved between the drive rollers 200; a conveying mechanism 500, disposed on the surface of the phenolic resin synthetic raw material conveyor belt 300, with multiple conveying boxes 510 evenly distributed on the surface of the phenolic resin synthetic raw material conveyor belt 300, a rotating rod 520 rotatably connected inside the conveying box 510, a stirring blade 530 disposed on the surface of the rotating rod 520, both ends of the rotating rod 520 extending through the surface of the conveying box 510 to the outside of the conveying box 510, and gears 540 fixedly connected to both ends; and racks 550 symmetrically arranged on the top of the supports 100 that mesh with the gears 540.

[0023] An automatic feeding device for phenolic resin synthesis using the above technical solution allows the phenolic resin synthesis raw material conveyor belt 300 and conveying mechanism 500 to be driven synchronously by a single drive motor 400. When the phenolic resin synthesis raw material conveyor belt 300 moves the conveying box 510, the gears 540 at both ends of the rotating rod 520 mesh with the rack 550 at the top of the support 100, thereby enabling the stirring blade 530 to rotate automatically. There is no need to configure a separate motor for each conveying box 510, which can reduce energy consumption and cost compared to the existing multi-motor solution. When the drive roller 200 rotates, it drives the drive pulley 660 to rotate, which in turn drives the fan blade 640 to rotate. The fan blade 640 generates cold air, which is precisely blown onto the raw materials through the air outlet 620. This effectively controls the temperature of the raw materials and prevents phenol and formaldehyde from undergoing premature prepolymerization due to temperature rise, ensuring that the activity of the raw materials meets the requirements of the synthesis process.

[0024] To provide power to the entire device, a drive motor 400 is fixedly mounted on one side of the bracket 100, and the output shaft of the drive motor 400 is fixedly connected to one end of a transmission roller 200. By directly and rigidly connecting the drive motor 400 to the transmission roller 200, power can be directly transmitted to the transmission roller 200, reducing power loss in intermediate transmission links and ensuring stable rotational speed of the transmission roller 200.

[0025] To ensure the uniform mixing of raw materials within the conveying box 510 by the stirring blades 530, and to extend the service life of the core components in corrosive environments, the stirring blades 530 are evenly distributed on the surface of the rotating rod 520. An anti-corrosion layer is provided on the inner wall of the conveying box 510, the rotating rod 520, and the surface of the stirring blades 530. This anti-corrosion layer can be a polytetrafluoroethylene coating, which effectively isolates metal components from corrosive materials such as phenol and formaldehyde, preventing rust and damage, and extending the service life of the core mixing components.

[0026] To achieve precise cooling of raw materials during the conveying process and prevent them from deteriorating due to temperature rise, a cooling mechanism 600 is installed on the support 100. The cooling mechanism 600 includes a fixed frame 610 fixedly connected to the surface of the support 100. Air outlets 620 are evenly distributed at the bottom of the fixed frame 610, facing the drive roller 200. The air outlets 620 facing the drive roller 200 allow cool air to be directly blown onto the surface of the raw materials inside the conveying box 510, reducing air loss during transmission and improving cooling efficiency.

[0027] To achieve efficient gathering and directional delivery of cold air, a guide hood 630 is fixedly installed on the top of the fixed frame 610. A fan blade 640 is rotatably connected inside the guide hood 630. The air outlet 620 of the guide hood 630 is connected to the fixed frame 610, and an air duct connected to the air outlet 620 is provided inside the fixed frame 610. The design of the air duct inside the fixed frame 610 can evenly distribute the gathered cold air to each air outlet 620, avoiding situations where some air outlets 620 have insufficient or excessive cold air, thus achieving uniform cooling of the raw materials in all conveying boxes 510.

[0028] To eliminate the need for a separate drive unit for the fan blade 640, a rotating shaft is fixedly connected to one side of the fan blade 640. A driven pulley 650 is fixedly connected to one end of the shaft, and a driving pulley 660 is fixedly connected to one end of the transmission roller 200. The driving pulley 660 and the driven pulley 650 are connected by a transmission belt 670. The transmission belt 670 transmits power from the transmission roller 200 to the fan blade 640, synchronizing the speed of the fan blade 640 with that of the transmission roller 200. When the conveying speed of the phenolic resin synthetic raw material conveyor belt 300 increases, the speed of the fan blade 640 also increases, resulting in a corresponding increase in the supply of cold air and further improving the accuracy and energy efficiency of cooling.

[0029] To adapt the device to production sites with varying flatness, an adjusting seat is fixedly connected to the bottom of the support leg 110. An adjusting bolt is threaded into the adjusting seat, and an anti-slip pad is rotatably connected to the bottom of the adjusting bolt. By rotating the adjusting bolt, the height of each support leg 110 can be adjusted individually, ensuring that the bracket 100 remains horizontal and guaranteeing the smooth operation of the phenolic resin synthetic raw material conveyor belt 300.

[0030] To prevent the phenolic resin synthetic material conveyor belt 300 from shifting laterally during long-term operation, an annular limiting groove is provided on the surface of the drive roller 200, and a limiting strip adapted to the limiting groove is fixedly connected to the inner wall of the phenolic resin synthetic material conveyor belt 300. The matching design of the limiting strip and the limiting groove forms a lateral constraint on the phenolic resin synthetic material conveyor belt 300, ensuring that the phenolic resin synthetic material conveyor belt 300 always runs stably along the axial direction of the drive roller 200.

[0031] To prevent airborne impurities from entering the conveyor box 510 and contaminating the raw materials, a detachable filter cotton, made of activated carbon composite cotton, is installed inside the air outlet 620. This activated carbon composite cotton has both filtration and adsorption functions: on the one hand, it filters dust, particles, and other impurities from the air, preventing them from contaminating the raw materials and affecting the quality of phenolic resin synthesis; on the other hand, it adsorbs harmful substances such as formaldehyde volatile gases from the air, reducing the concentration of harmful gases in the workshop and improving the working environment. Furthermore, the filter cotton is detachable, facilitating regular replacement and ensuring long-term stable filtration and adsorption performance.

[0032] To achieve precise control of the feed rate, the conveying speed is dynamically adjusted according to the raw material requirements of the subsequent reactor. An infrared sensor is fixedly installed on one side of the support 100, corresponding to the position of the conveyor box 510, and is electrically connected to a controller, which is electrically connected to the drive motor 400. The infrared sensor can detect the number of conveyor boxes 510 passing through in real time and transmit the signal to the controller. The controller automatically calculates and adjusts the speed of the drive motor 400 according to the preset feed rate parameters. When too many conveyor boxes 510 are detected, the controller reduces the motor speed; when too few are detected, the controller increases the motor speed.

[0033] In summary, the automatic feeding device for phenolic resin synthesis provided in this embodiment has the following advantages: This device can synchronously drive the phenolic resin synthesis raw material conveyor belt 300 and the conveying mechanism 500 with only one drive motor 400. When the phenolic resin synthesis raw material conveyor belt 300 drives the conveyor box 510 to move, the gears 540 at both ends of the rotating rod 520 mesh with the rack 550 at the top of the bracket 100, realizing the automatic rotation of the stirring blade 530. There is no need to configure a separate motor for each conveyor box 510. Compared with the existing multi-motor solution, energy consumption and cost can be reduced. When the transmission roller 200 rotates, it drives the active pulley 660 to rotate, which in turn drives the fan blade 640 to rotate. The fan blade 640 generates cold air, which is precisely blown onto the raw material through the air outlet 620, effectively controlling the raw material temperature and preventing phenol and formaldehyde from undergoing prepolymerization reaction prematurely due to temperature rise, ensuring that the activity of the raw material meets the requirements of the synthesis process.

[0034] In use, first adjust the device level using the adjusting bolts at the bottom of the support leg 110 to ensure the smooth operation of the phenolic resin synthesis raw material conveyor belt 300; then start the drive motor 400, which drives the transmission roller 200 to rotate, thereby causing the phenolic resin synthesis raw material conveyor belt 300 to move the conveyor box 510; during the movement of the conveyor box 510, the gears 540 and rack 550 at both ends of the rotating rod 520 mesh, driving the stirring blades 530 to rotate and stir the phenolic resin synthesis raw material; at the same time, the transmission roller 200 drives the drive pulley 660 to rotate, which in turn drives the driven pulley 650 and fan blades 640 to rotate through the transmission belt 670, and the cold air is blown from the air outlet 620 through the air guide 630 and the air passage of the fixed frame 610 to the raw material for cooling.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
