Description

Technical Field

[0001] This utility model relates to the field of polyurethane resin production technology, specifically to a feeding device for polyurethane resin production. Background Technology

[0002] Polyurethane, also known as polyurethane, is a high-molecular-weight material with excellent mechanical properties formed by the condensation reaction of polyols and polyisocyanates. It is extremely ductile and polyurethane resins can be used in coatings, adhesives, fabric finishing agents, leather finishing agents, polyurethane flexible / rigid foams, elastomers, etc., and are applied in textiles, construction, aviation, shipbuilding, transportation, medicine, electronics and other fields.

[0003] Polyurethane resin production requires mixing raw materials with catalysts or additives, necessitating the use of mixing equipment. However, traditional mixing equipment typically adds raw materials via a feed pipe or pre-drilled feed port. This type of feeding device has a simple overall structure and cannot quantitatively feed the raw materials. During the mixing process, if too much raw material is added at once, it can cause agglomeration within the mixing equipment, affecting the mixing effect between the raw materials and additives. Furthermore, traditional feeding devices cannot screen the added raw materials, and some excessively large particles are difficult to dissolve after entering the equipment, easily impacting the mixing efficiency.

[0004] Therefore, we propose a feeding device for polyurethane resin production. Utility Model Content

[0005] The purpose of this invention is to provide a feeding device for polyurethane resin production, so as to solve the problems mentioned in the background art.

[0007] Optionally, limiting components are fixedly installed on one side of each of the two second toothed discs that are close to each other. Both limiting components are rotatably connected to the inner wall of the feeding seat, and the second toothed discs can be limited by the limiting components.

The two sliding components are slidably sleeved on the corresponding sliding rods, and the lifting frames can be limited by the sliding components and sliding rods.

[0009] Optionally, the screen box is fixedly installed with locking strips on both sides, and the screening frame is provided with slots corresponding to the two locking strips. The locking strips are inserted into the slots, and the screen box is easily disassembled and assembled through the locking strips and slots.

[0010] Optionally, the top of the screening frame is threaded with two fixing bolts, the bottom ends of which extend into the clamping strip, so that the clamping strip can be limited by the fixing bolts.

[0011] Optionally, the mounting plate has multiple mounting holes on both sides of the feeding seat, which facilitates the use of external bolts to fix the device at the feed inlet at the top of the mixing equipment.

[0022] Two second toothed discs 16 are fixedly installed with limiting components 21 on one side close to each other. Both limiting components 21 are rotatably connected to the inner wall of the feeding seat 2. The limiting components 21 can limit the second toothed discs 16. U-shaped frames 6 are fixedly installed on both sides of the second toothed discs 16 at the front and rear ends of the feeding seat 2. Slide rods 7 are fixedly installed in both U-shaped frames 6. Slide pieces 8 are fixedly installed on both sides of each lifting frame 4. The two slide pieces 8 are slidably sleeved on the corresponding slide rods 7. The lifting frame 4 can be limited by the slide pieces 8 and slide rods 7. The screen box 9 is fixedly installed with locking strips 10 on both sides. The screening frame 3 is provided with slots 11 corresponding to the two locking strips 10. The locking strips 10 are inserted into the slots. Inside 11, the screen box 9 is easily disassembled and assembled via the clip 10 and the slot 11. The top of the screening frame 3 is threaded with two fixing bolts 18, the bottom ends of which extend into the clip 10. The fixing bolts 18 are used to limit the clip 10. Multiple mounting holes 19 are provided on both sides of the feeding seat 2 on the mounting plate 1. The multiple mounting holes 19 are used to fix the equipment at the feed inlet at the top of the mixing equipment with external bolts. A motor 14 is fixedly installed on the mounting plate 1 at the rear of the feeding seat 2. The output end of the motor 14 is fixedly installed on one of the first gear discs 15. The first gear disc 15 is rotated by the motor 14, which is beneficial to the use of the equipment.

[0023] Working principle: The motor 14 is electrically connected to the external PLC controller via a connecting cable. During use, the device is fixed to the top of the mixing equipment using multiple external bolts and mounting holes 19, ensuring the bottom opening of the feeding seat 2 connects to the pre-reserved feed inlet at the top of the mixing equipment. The raw materials to be added are then poured into the screen box 9. Materials meeting the usage standards quickly pass through the mesh of the screen box 9 and fall into the feeding seat 2. Some of the raw materials enter the quantitative tank 17. Turning on the motor 14 causes it to drive the transmission rod 12, conveyor wheel 13, first toothed disc 15, and second toothed disc 16 to rotate. Each rotation of the conveyor wheel 13 adds a certain amount of raw material to the mixing equipment through the feed inlet, achieving quantitative addition of raw materials. During the rotation of the second toothed disc 16, the push rod 5 rotates in a circumferential direction. The lifting frame 4 and the top rod 22 move up and down reciprocally. The two top rods 22 drive the screening frame 3 to vibrate up and down, which can quickly screen the raw materials in the screen box 9. The rotation speed of the motor 14 can be adjusted by the PLC controller to meet the needs of different feeding speeds. When it is necessary to clean and recycle raw materials that do not meet the standards, first remove the two fixing bolts 18, and then pull the screen box 9 backward to pour out the filtered raw materials. This feeding device for polyurethane resin production is easy to use. The above components can be used to feed quantitatively, avoiding the addition of too much raw material at one time, which would cause the material in the mixing equipment to agglomerate during mixing and affect the mixing effect. At the same time, it can screen the raw materials before feeding to prevent the raw materials with excessively large particles from entering the mixing equipment and being difficult to dissolve, thus affecting the mixing efficiency.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
