DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] When implementing: Figure 1-5 As shown, a mixing and stirring device for the production and processing of urea resin comprises: a bottom plate 100, a spherical tank body 200 is fixedly connected to the top of the bottom plate 100; a mixing mechanism 300, the mixing mechanism 300 comprises a vertical rod 310 rotatably connected to the top of the spherical tank body 200, the bottom end of the vertical rod 310 penetrates into the spherical tank body 200 and is fixedly connected to two arc-shaped stirring rods 380, a servo motor 320 is fixedly connected to the upper surface of the spherical tank body 200, a bevel gear 330 is fixedly connected to the output shaft of the servo motor 320 and the surface of the vertical rod 310, a driving assembly 370 is arranged on the surface of the spherical tank body 200, a plurality of telescopic rods 350 are hinged to the surface of the vertical rod 310, a hinged rod 360 is hinged to the surface of the telescopic rod 350, and a sliding rod 340 sliding with the vertical rod 310 is hinged at the other end of the hinged rod 360.

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, the driving assembly 370 includes an air storage box 371 fixedly connected to the surface of the spherical tank body 200, the inner wall of the air storage box 371 is provided with an extrusion plate 372, one end of the extrusion plate 372 passes through the air storage box 371 and is fixedly connected to a contact plate 373, the output shaft surface of the servo motor 320 is fixedly connected to a cam 374 that fits tightly with the contact plate 373, a second air pipe 377 is embedded in the vertical rod 310, a plurality of driving cylinders 378 connected to the second air pipe 377 are provided in the vertical rod 310, a driving rod 379 is provided on the inner wall of the driving cylinder 378, one end of the driving rod 379 passes through the driving cylinder 378 and is fixedly connected to the sliding rod 340, and a first air pipe 376 is provided between the second air pipe 377 and the air storage box 371. The servo motor 320 drives the cam 374 to rotate and squeeze the contact plate 373. The first spring 375 is bent under force. The contact plate 373 drives the squeezing plate 372 to slide in the gas storage box 371 and squeezes out the gas. Under the action of the first air pipe 376 and the second air pipe 377, the gas is transported to the driving cylinder 378, thereby driving the driving rod 379 to push the sliding rod 340. The sliding rod 340 drives the telescopic rod 350 to run in a reciprocating path to mix the raw materials of the urea resin. After mixing, the raw materials can be discharged using the discharge pipe 210.

[0028] The surface of the vertical rod 310 is provided with a plurality of sliding grooves 312, and the sliding rod 340 and the driving rod 379 both slide on the inner wall of the sliding groove 312. The sliding rod 340 is limited when moving to prevent it from deflecting, and the lower opening of the sliding groove 312 is inclined to better discharge the raw materials.

[0029] One end of the second air pipe 377 is provided with a sealing bearing 311, and the inner edge of the sealing bearing 311 is fixedly connected to one end of the first air pipe 376. This prevents the first air pipe 376 from rotating with the second air pipe 377, effectively protects the first air pipe 376, and prolongs its service life.

[0030] One end of the air storage box 371 is fixedly connected to two first springs 375, and the other end of the first spring 375 is fixedly connected to the contact plate 373. The first spring 375 can give a certain force to the contact plate 373 to make it close to the cam 374.

[0031] like Figure 5 As shown, the telescopic rod 350 includes a first connecting rod 351 hinged to the vertical rod 310, the surface of the first connecting rod 351 is hinged to the hinge rod 360, one end of the inner wall of the first connecting rod 351 is fixedly connected to the second spring 352, the other end of the second spring 352 is fixedly connected to the second connecting rod 353, and the other end of the second connecting rod 353 passes through the first connecting rod 351. Under the action of the second spring 352, when the first connecting rod 351 and the second connecting rod 353 move, they will still be close to the inner wall of the arc-shaped stirring rod 380, and there will be no position deviation, so that the length is self-adjusted during the swinging process.

[0032] The other end of the second connecting rod 353 is hinged with a positioning plate 354, and the other side of the positioning plate 354 is closely attached to the inner wall of the arc-shaped stirring rod 380. In cooperation with the second spring 352, the positioning plate 354 will be closely attached to the inner wall of the arc-shaped stirring rod 380, increasing the stability of the operation of the telescopic rod 350. At the same time, under the push of this force, the positioning plate 354 can also scrape the inner wall of the arc-shaped stirring rod 380 to ensure its long-term operation.

[0033] like Figure 1 As shown, two discharge pipes 210 are arranged on the lower surface of the spherical tank body 200, and electromagnetic valves are arranged on the surface of the discharge pipes 210, and a collection box 110 is arranged at the middle of the top of the bottom plate 100, so as to better realize discharge and collection.

[0034] When the utility model is in use, the urea resin raw material is placed into the spherical tank body 200. After the placement is completed, the servo motor 320 is started. Under the action of the two bevel gears 330, the vertical rod 310 rotates, thereby driving the telescopic rod 350, the hinge rod 360, the sliding rod 340 and the arc stirring rod 380 to rotate synchronously with the vertical rod 310. During this process, the cam 374 rotates synchronously with the bevel gear 330, and the cam 374 squeezes the contact plate 373. The first spring 375 is bent under force, and the contact plate 373 drives the squeezing plate 372 to slide in the air storage box 371 and squeezes out the gas. Under the action of the first air pipe 376 and the second air pipe 377, the gas is transported to the driving cylinder 378, thereby driving the driving rod 379 to push the sliding rod 340. The sliding rod 340 drives the telescopic rod 350 to run in a reciprocating path to mix the urea resin raw materials. After mixing and combining, the raw materials can be discharged using the discharge pipe 210.

[0035] It should be noted that the sealed bearings, servo motors, solenoid valves, etc. in the above description are all devices with relatively mature application of existing technologies. The specific models can be selected according to actual needs. At the same time, the servo motors and solenoid valves can be powered by built-in power supplies or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0036] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
