A bevel gear is fixed to one end of the crank and the outer wall of the connecting shaft. A connecting rod is hinged to the outer wall of the crank, and a connecting lug is hinged to the top of the connecting rod's outer wall. This patent has the following drawbacks: although it can mix and stir chemically synthesized materials, the preheated mixture has high viscosity and poor flowability, making it prone to accumulating at the outlet, causing blockages and affecting the efficiency of the mixed material discharge. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that the preheated and mixed chemical synthetic materials are prone to accumulation at the discharge port due to their high viscosity, which makes it difficult to discharge them. Therefore, this invention proposes a preheating and mixing device for chemical synthetic materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A preheating and mixing device for chemically synthesized materials includes a mixing tank and a feed pipe fixedly installed on the mixing tank. A stirring rod is rotatably installed inside the mixing tank, and a discharge pipe is installed at the bottom of the mixing tank. The device also includes a conical cover fixedly installed inside the mixing tank. A reciprocating screw is fixedly connected to the bottom of the stirring rod, and a slider is threaded onto the reciprocating screw. Multiple push rods are fixedly connected around the bottom of the slider, and a push block is fixedly connected to the bottom of each push rod. A guide block is fixedly installed inside the conical cover, and each push rod is slidably connected to the guide block.

[0007] Preferably, a heating shell is fixedly installed on the outside of the mixing tank, and a servo motor is fixedly installed on the top of the heating shell. The output end of the servo motor extends into the mixing tank and is fixedly connected to the stirring rod.

[0008] Preferably, a plurality of fixing rods are fixedly connected to the lower wall of the mixing tank, the conical cover is fixedly connected to the plurality of fixing rods, and the reciprocating screw is rotatably connected inside the conical cover.

[0009] Preferably, support rods are fixedly connected to the inner walls of both sides of the conical cover, the guide block is fixedly connected between the two support rods, and bearing plates are fixedly connected to both sides of the top of the heating shell.

[0010] Preferably, each of the two bearing plates is rotatably connected to a rotating rod, and each of the two rotating rods is connected to the output end of the servo motor by a synchronous belt.

[0011] Preferably, cams are fixedly connected to the bottom of both rotating rods, the two cams are arranged in the same direction, and U-shaped plates are fixedly connected to the outer walls of both sides of the heating shell.

[0013] Preferably, each of the two slide rods is fitted with a spring, and the two ends of the spring are fixedly connected to a U-shaped plate and an abutment block, respectively. A U-shaped scraper corresponding to the mixing tank is fixedly connected to the stirring rod.

[0014] Compared with the prior art, this utility model provides a preheating and mixing device for chemically synthesized materials, which has the following beneficial effects:

[0015] 1. The preheating and mixing equipment for this chemically synthesized material uses a continuously rotating stirring rod to drive a reciprocating screw to rotate continuously inside a conical shroud. Guided by a guide block, the push rod causes the slider and push rod to move up and down on the reciprocating screw, thereby driving multiple push blocks to move up and down repeatedly, pushing the mixed chemically synthesized material downwards. This assists in the feeding speed when the chemically synthesized material is discharged outwards, automatically prevents the chemically synthesized material from accumulating in the discharge pipe during discharge, prevents blockage, increases fluidity, speeds up the discharge, and improves production efficiency.

[0016] 2. The preheating and mixing equipment for this chemically synthesized material uses two synchronous belts to automatically drive two rotating rods to rotate simultaneously, which in turn automatically drive two cams to rotate simultaneously. Under the reciprocating contact between the cam protrusions and the contact blocks, the sliding rod drives the rubber hammer to reciprocate to strike the heating shell, causing the left and right sides of the mixing tank to vibrate. This loosens and removes the material adhering to the inner wall of the mixing tank, preventing local material retention or uneven concentration. It also prevents local overheating or overcooling, promotes material flow, breaks up dead zones, and improves the mixing effect, production efficiency, and discharge rate of the chemically synthesized material.

[0026] Reference Figures 1-6A preheating and mixing device for chemically synthesized materials includes a mixing tank 1 and a feed pipe 2 fixedly installed on the mixing tank 1. A stirring rod 3 is rotatably installed inside the mixing tank 1, and a discharge pipe 4 is installed at the bottom of the mixing tank 1. The device also includes a conical cover 5 fixedly installed inside the mixing tank 1. A reciprocating screw 6 is fixedly connected to the bottom of the stirring rod 3. A slider 7 is threaded onto the reciprocating screw 6. Multiple push rods 8 are fixedly connected to the bottom of the slider 7. A push block 9 is fixedly connected to the bottom of each push rod 8. A guide block 10 is fixedly installed inside the conical cover 5. Each push rod 8 is slidably connected to the guide block 10. The continuous rotation of the stirring rod 3 drives the reciprocating screw 6 to rotate continuously within the conical cover 5, pushing... Guided by the guide block 10, the rod 8 causes the slider 7 and push rod 8 to reciprocate up and down on the reciprocating screw 6, which in turn drives multiple push blocks 9 to reciprocate up and down, repeatedly pushing the mixed chemical synthesis material downwards. This assists in the feeding speed when the chemical synthesis material is discharged outwards, automatically prevents the chemical synthesis material from accumulating in the discharge pipe 4 during discharge, prevents blockage, increases fluidity, speeds up the discharge, and improves production efficiency. It should be noted that the multiple push blocks 9 are located directly above the discharge pipe 4. The preheated chemical synthesis material can be automatically mixed under the action of the stirring rod 3 when other materials are added later, and will not be affected by the up and down reciprocating pushing of the push blocks 9.

[0027] A heating shell 11 is fixedly installed on the outside of the mixing tank 1. A servo motor 12 is fixedly installed on the top of the heating shell 11. The output end of the servo motor 12 extends into the mixing tank 1 and is fixedly connected to the stirring rod 3. By starting the servo motor 12, the stirring rod 3 can be driven to rotate continuously, so as to uniformly stir and mix the chemical synthesis materials. The heating shell 11 can be used to preheat the materials before mixing, so that the temperature inside the mixing tank 1 can be raised in advance.

[0028] Multiple fixing rods 13 are fixedly connected to the lower wall of the mixing tank 1. The conical cover 5 is fixedly connected to the multiple fixing rods 13. The reciprocating screw 6 is rotatably connected inside the conical cover 5. The multiple fixing rods 13 can fix the conical cover 5. It should be noted that the conical cover 5 is made of smooth material, which can prevent the mixed material from accumulating on the conical cover 5.

[0029] Support rods 14 are fixedly connected to the inner walls of both sides of the conical cover 5, and guide blocks 10 are fixedly connected between the two support rods 14. Bearing plates 15 are fixedly connected to both sides of the top of the heating shell 11.

[0030] Two bearing plates 15 are each rotatably connected to a rotating rod 16, and both rotating rods 16 are connected to the output end of the servo motor 12 by a synchronous belt 17.

[0031] The bottom of each of the two rotating rods 16 is fixedly connected to a cam 18, which is set in the same direction. U-shaped plates 19 are fixedly connected to the outer walls of both sides of the heating shell 11. When the servo motor 12 is started, the two rotating rods 16 can be automatically driven to rotate simultaneously through the two synchronous belts 17, which in turn automatically drives the two cams 18 to rotate simultaneously. Through the two cams 18 set in the same direction, the two sides of the mixing tank 1 can vibrate respectively.

[0032] Each of the two U-shaped plates 19 is slidably connected to a slide rod 20, and the two ends of the slide rod 20 are respectively connected to a rubber hammer 21 and a contact block 24.

[0033] Springs 22 are fitted onto both sliding rods 20. The two ends of the springs 22 are fixedly connected to the U-shaped plate 19 and the contact block 24, respectively. A U-shaped scraper 23 corresponding to the mixing tank 1 is fixedly connected to the stirring rod 3. When the protrusion of the cam 18 contacts the contact block 24, the sliding rod 20 slides on the U-shaped plate 19, compressing the springs 22. Simultaneously, the rubber hammer 21 lightly taps the outer wall of the heating shell 11 once. Since the heating shell 11 is fixedly connected to the mixing tank 1, when the heating shell 11 vibrates, it vibrates synchronously with the mixing tank 1. When the protrusion of the cam 18 disengages from the contact block 24, the sliding rod 20 and the rubber hammer 21 automatically reset under the action of the springs 22. Therefore, the reciprocating contact between the protrusion of the cam 18 and the contact block 24... When the stirring rod 3 is touched, the sliding rod 20 drives the rubber hammer 21 to reciprocate and strike the heating shell 11, causing the left and right sides of the mixing tank 1 to vibrate. This loosens and removes the material adhering to the inner wall of the mixing tank 1, preventing local material retention or uneven concentration. It also prevents local overheating or overcooling, promotes material flow, and breaks up dead zones. While the stirring rod 3 continues to rotate, it also drives the U-shaped scraper 23 to rotate simultaneously. The U-shaped scraper 23 continuously scrapes along the inner wall of the mixing tank 1, which removes the chemical materials adhering to the inner wall of the mixing tank 1, reducing material waste and preventing uneven mixing. It also helps to clean the mixing tank 1 more thoroughly in subsequent cleaning with the rubber hammer 21, making it easier to mix different chemical materials next time.

[0034] In this invention, during use, the mixing tank 1 is preheated by the heating shell 11. Then, the servo motor 12 drives the stirring rod 3 to rotate. Chemical materials are then added through the feed pipe 2 for mixing. Simultaneously, the stirring rod 3 drives the reciprocating screw 6 to rotate synchronously. Guided by the guide block 10, the push rod 8 causes the slider 7 and push rod 8 to reciprocate up and down on the reciprocating screw 6, thereby driving multiple push blocks 9 to reciprocate up and down, repeatedly pushing the mixed chemical material downwards. This assists in the discharge speed of the chemical material, automatically preventing accumulation of the chemical material in the discharge pipe 4 during discharge, preventing blockage, increasing fluidity, accelerating discharge speed, and improving production efficiency. Furthermore, while the mixing tank 1 continuously mixes the materials, two synchronous belts 17 automatically drive two rotating rods 16 to rotate simultaneously, which in turn automatically drive two cams 18 to rotate simultaneously. When the protrusion of cam 18 contacts the contact block 24, the slide rod 20 slides on the U-shaped plate 19 and compresses the spring 22. At the same time, it drives the rubber hammer 21 to lightly tap the outer wall of the heating shell 11 once. Since the heating shell 11 is fixedly connected to the mixing tank 1, when the heating shell 11 vibrates, it will vibrate synchronously with the mixing tank 1. When the protrusion of cam 18 disengages from the contact block 24, the slide rod 20 and the rubber hammer 21 will automatically reset under the action of the spring 22. Therefore, under the reciprocating contact between the protrusion of cam 18 and the contact block 24, the slide rod 20 drives the rubber hammer 21 to reciprocate to tap the heating shell 11, causing the left and right sides of the mixing tank 1 to vibrate respectively. This can loosen and remove the material stuck to the inner wall of the mixing tank 1, avoid local material retention or uneven concentration, and also avoid local overheating or overcooling, promote material flow, destroy dead flow corners, and improve the mixing effect, production efficiency and discharge speed of chemical synthesis materials.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
