Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a raw material addition device for processing. Background Technology

[0002] Plastic additives are chemical substances that are dispersed in the molecular structure of plastics and do not seriously affect the molecular structure of plastics, but can improve their properties or reduce costs. The addition of additives can improve the processability, physical properties, chemical properties and other functions of the plastic substrate and increase the physical and chemical properties of the substrate. During the production of plastic additive granules, the raw materials need to be transported internally through a feeding device.

[0003] The currently published patent, CN219838058U, discloses an additive device for producing plastic additive granules. Multiple plastic additive raw materials are fed into the inlet, and a stirring motor controls the rotation of the mixing rod to stir the additives. After stirring, a baffle plate is pulled out of the storage tank, connecting the mixing chamber and the storage chamber. Additive powder falls from the mixing tank into the storage tank. The baffle plate is then replaced, separating the mixing tank and the storage tank again. This allows the device to continue adding and stirring plastic additive raw materials in the mixing tank while feeding the additives.

[0004] Based on the above search results, it was found that when using this additive device, various plastic additive raw materials are put into the feed port, and then the stirring motor controls the mixing rod to rotate and stir the additives. Although it can stir and mix the plastic additive raw materials, the workers directly pour the additive raw materials into the mixing tank all at once. Since the amount of additive raw materials added when mixing with plastic is small, the additives tend to accumulate inside the mixing tank when added directly at once, affecting the uniformity of the additive distribution inside the mixing tank, and thus affecting the uniformity of the additive mixing and reducing the mixing effect. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a raw material addition device for processing, which can solve the problem that when workers add the additives directly at one time, the additives tend to accumulate inside the mixing tank, affecting the uniformity of the additive distribution inside the mixing tank, and thus affecting the uniformity of the additive mixing and reducing the mixing effect of the additives.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material addition device for processing, comprising a mixing tank and an additive slow feeding device; a rotating shaft is rotatably connected inside the mixing tank, the upper end of the rotating shaft extends to the outside of the mixing tank, a second gear is fixedly connected to the upper end of the rotating shaft, two supporting inclined rods are fixedly connected to the top of the mixing tank, and a feeding tank is fixedly connected to the upper ends of the two supporting inclined rods; the additive slow feeding device comprises a rotating rod, a first gear, a disc, and a spiral scraper, the rotating rod is rotatably connected inside the feeding tank, the upper end of the rotating rod extends to the outside of the feeding tank, the first gear is fixedly connected to the upper end of the rotating rod, the first gear meshes with the second gear, the disc is fixedly connected to the lower end of the rotating rod, the disc is rotatably installed inside the feeding tank, and a feeding hole is opened on the surface of the disc.

[0007] Preferably, a discharge pipe is fixedly installed on the surface of the mixing tank, and a feed pipe is fixedly installed on the top of the mixing tank.

[0012] Preferably, the spiral scraper is fixedly connected to the top of the disc, and the surface of the spiral scraper is in contact with the inner wall of the feeding tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The raw material adding device for this processing uses a rotating disc that drives a spiral scraper to rotate and scrape the inner wall of the feeding tank, preventing additives from adhering to the inner wall of the feeding tank. This improves the smoothness of the additives being discharged into the mixing tank through the discharge hole and conveying pipe. By adding the additives slowly, the operator prevents the additives from accumulating inside the mixing tank, improves the uniformity of the additives' distribution inside the mixing tank, and thus improves the uniformity of the additive mixing, thereby improving the mixing effect of the additives and plastics.

[0025] Please see Figure 1-4This utility model provides a technical solution: a raw material addition device for processing, including a mixing tank 1 and an additive slow feeding device. A discharge pipe 2 is fixedly installed on the surface of the mixing tank 1, a feed pipe 3 is fixedly installed on the top of the mixing tank 1, a drive motor 4 is fixedly installed on the bottom of the mixing tank 1, a rotating shaft 5 is rotatably connected inside the mixing tank 1, the lower end of the rotating shaft 5 is fixedly connected to the output end of the drive motor 4, the upper end of the rotating shaft 5 extends to the outside of the mixing tank 1, a second gear 13 is fixedly connected to the upper end of the rotating shaft 5, two supporting inclined rods 7 are fixedly connected to the top of the mixing tank 1, a feeding tank 8 is fixedly connected to the upper end of the two supporting inclined rods 7, a conveying pipe 9 is fixedly connected to the bottom of the feeding tank 8, the conveying pipe 9 is located at an eccentric position at the bottom of the feeding tank 8, the lower end of the conveying pipe 9 extends to the inside of the mixing tank 1, and a conical feeding hopper 10 is fixedly installed on the surface of the feeding tank 8.

[0026] The slow additive feeding device includes a rotating rod 11, a first gear 12, a disc 14, and a spiral scraper 16. The rotating rod 11 is rotatably connected to the inside of the feeding tank 8, and the upper end of the rotating rod 11 extends to the outside of the feeding tank 8. The first gear 12 is fixedly connected to the upper end of the rotating rod 11 and meshes with the second gear 13. The disc 14 is fixedly connected to the lower end of the rotating rod 11 and is rotatably installed inside the feeding tank 8. A feeding hole 15 is opened on the surface of the disc 14. The feeding hole 15 is located at an eccentric position on the disc 14, and the size of the feeding hole 15 is the same as the diameter of the conveying pipe 9. The spiral scraper 16 is fixedly connected to the top of the disc 14, and the surface of the spiral scraper 16 is in contact with the inner wall of the feeding tank 8.

[0027] After the worker pours the plastic raw material into the mixing tank 1 through the feed pipe 3, and then starts the drive motor 4, the output of the drive motor 4 rotates, which drives the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the mixing shaft 6 to rotate and mix the plastic raw material. Then, the worker pours the additive into the feeding tank 8 through the conical feeding hopper 10. When the rotating shaft 5 rotates, it drives the second gear 13 to rotate. The rotation of the second gear 13 drives the first gear 12 and the rotating rod 11 to rotate simultaneously. The rotation of the rotating rod 11 drives the disc 14 to rotate inside the feeding tank 8. When the disc 14 rotates once, it drives the discharge hole 15 to rotate once, so that the discharge hole 15 coincides with the inlet at the top of the conveying pipe 9 once. At this time, the inside of the feeding tank 8... The additives can fall into the inside of the conveying pipe 9 through the discharge hole 15 under their own gravity, and then be transported to the inside of the mixing tank 1 to mix with the plastic. This allows the additives in the feeding tank 8 to be discharged slowly and quantitatively. When the disc 14 rotates, it can drive the spiral scraper 16 to rotate and scrape the inner wall of the feeding tank 8, preventing the additives from adhering to the inner wall of the feeding tank 8. This improves the smoothness of the additives being discharged into the mixing tank 1 through the discharge hole 15 and the conveying pipe 9. By adding the additives slowly, the operator can prevent the additives from accumulating inside the mixing tank 1, improve the uniformity of the additives distribution inside the mixing tank 1, and thus improve the uniformity of the additive mixing and the mixing effect of the additives and plastics.
