The deflection adjustment ring mechanism 4 includes a fixed plate 401 fixed to the height adjustment block 303. The fixed plate 401 is rotatably connected to a first deflection shaft 402. The first deflection shaft 402 penetrates through the fixed plate 401 and the height adjustment block 303. The first deflection shaft 402 is fixedly connected to a mounting ring 403. The first deflection shaft 402 is fixedly connected to a deflection rod 404. The deflection rod 404 is rotatably connected to a second deflection shaft 405. The fixed plate 401 is rotatably connected to a third deflection shaft 406. A second hydraulic telescopic rod 407 is rotatably connected between the second deflection shaft 405 and the third deflection shaft 406.
[0027] Specifically, turning on the first hydraulic telescopic rod 302 can drive the height adjustment block 303 to rise and fall along the main fixed frame 301, thereby adjusting the height of the first deflection shaft 402 and the mounting ring 403.
[0028] In addition, turning on the second hydraulic telescopic rod 407 can drive the second deflection shaft 405, thereby driving the deflection rod 404 to deflect and displace, and then driving the first deflection shaft 402 to deflect, so as to drive the mounting ring 403 to deflect and displace.
[0029] The conveying and adjusting cylinder mechanism 5 includes a conveying cylinder 501 rotatably connected to the mounting ring 403. Both ends of the conveying cylinder 501 are fixedly connected with retaining rings 502. A discharge groove 503 is provided on the retaining ring 502.

The output shaft of the rotary drive motor 602 is fixedly connected with a drive shaft 603. A torque sensor is provided on the drive shaft 603. The end of the drive shaft 603 is fixedly connected with a first drive gear 604. The first drive gear 604 meshes with a second drive gear 605.

An inlet and outlet port 704 is provided on the end retaining shell 703. The end retaining shell 703 is rotatably connected with the conveying cylinder 501 and the retaining ring 502.
[0030] Specifically, when the rotary drive motor 602 is turned on, the rotation of the output shaft of the rotary drive motor 602 will drive the drive shaft 603 to rotate. The rotation of the drive shaft 603 will drive the first drive gear 604 to rotate. The rotation of the first drive gear 604 will drive the second drive gear 605 to rotate. The rotation of the second drive gear 605 will drive the conveying cylinder 501 to rotate. The rotation of the conveying cylinder 501 can drive the spiral conveying blade 504 inside it to rotate. As the spiral conveying blade 504 rotates, it can drive the material to move, and finally the material is discharged through the inlet and outlet port 704 on the end retaining shell 703. When the heating wire is turned on, it can heat the material that needs to be heated.
[0031] The described adjusting scraping mechanism 9 includes a sliding sleeve 901 slidably connected to the fixed sliding rod 8. A limiting strip is provided in the axial direction of the inner axis of the sliding sleeve 901, and a limiting groove is provided in the axial direction of the fixed sliding rod 8. The limiting strip is located in the limiting groove and is slidably connected to the fixed sliding rod 8. Annular grooves are provided at both ends of the fixed sliding rod 8, and the annular grooves communicate with the limiting groove. The sliding sleeve 901 is fixedly connected to a first fixed plate housing 902 and a second fixed plate housing 903. The first fixed plate housing 902 and the second fixed plate housing 903 are symmetrically arranged on the sliding sleeve 901. A first fixed plate 904 is fixedly connected inside the first fixed plate housing 902. A first spring 905 and a second spring 906 are respectively fixedly connected to both sides of the first fixed plate 904. The end of the first spring 905 is fixedly connected to a first scraping plate 907, and the end of the second spring 906 is fixedly connected to a second scraping plate 908. The first scraping plate 907 and the second scraping plate 908 are slidably connected to the first fixed plate housing 902. A second fixed plate 909 is fixedly connected inside the second fixed plate housing 903. A third spring 910 and a fourth spring 911 are respectively fixedly connected to both sides of the second fixed plate 909. The end of the third spring 910 is fixedly connected to a third scraping plate 912, and the end of the fourth spring 911 is fixedly connected to a fourth scraping plate 913. The third scraping plate 912 and the fourth scraping plate 913 are slidably connected to the second fixed plate housing 903.
[0032] Specifically, since the sliding sleeve 901 is arranged outside the fixed sliding rod 8, and at the same time, the sides of the first fixed plate housing 902 and the second fixed plate housing 903 away from the sliding sleeve 901 are in contact with the conveying cylinder 501. Similarly, the first scraping plate 907, the second scraping plate 908, the third scraping plate 912, and the fourth scraping plate 913 are in contact with the conveying cylinder 501. At the same time, the second scraping plate 908 and the third scraping plate 912 are stuck at the same position, and the first scraping plate 907 and the fourth scraping plate 913 are in contact with the adjacent spiral conveying blades 504. As the conveying cylinder 501 rotates, it drives the spiral conveying blades 504 to rotate, thereby driving the first scraping plate 907, the second scraping plate 908, the third scraping plate 912, and the fourth scraping plate 913 to move, causing the sliding sleeve 901 to move along the fixed sliding rod 8 to scrape the materials attached to the conveying cylinder 501 and the spiral conveying blades 504.
[0033] In addition, when the first scraper 907, the second scraper 908, the third scraper 912, and the fourth scraper 913 move to the end to contact the retaining ring 502, at the same time, the limiting strip on the sliding sleeve 901 has not yet moved to the annular groove. At this time, the torque on the drive shaft 603 increases, and the torque sensor on the drive shaft 603 senses the torque. When the specified torque is reached, the rotary drive motor 602 is reversed, so as to drive the first scraper 907, the second scraper 908, the third scraper 912, and the fourth scraper 913 to move in the opposite direction. At the same time, the spiral conveyor blade 504 is driven to move in the opposite direction, and the material attached to the conveying cylinder 501 and the spiral conveyor blade 504 is scraped reciprocally, and at the same time, the reverse conveying of the material is realized, so as to effectively process the material, that is, heating or mixing treatment. When the torque of the reverse rotation of the rotary drive motor 602 is adjusted and increased, when the first scraper 907, the second scraper 908, the third scraper 912, and the fourth scraper 913 move to the end to contact the retaining ring 502, the spring is compressed at this time, and at the same time, the limiting strip is stuck into the annular groove. At this time, the spiral conveyor blade 504 will no longer drive the first scraper 907, the second scraper 908, the third scraper 912, and the fourth scraper 913 to move, and the sliding sleeve 901 will no longer move along the fixed slide rod 8, so as to cancel the scraping action on the material attached to the conveying cylinder 501 and the spiral conveyor blade 504.
[0034] Embodiment 2. Continuing to refer to Figures 1-3 In the embodiment of the present invention, the rotation displacement wheel mechanism 2 includes a deflection displacement shaft 201 rotatably connected to the mounting base plate 1. One end of the deflection displacement shaft 201 away from the mounting base plate 1 is fixedly connected to a rotation displacement wheel seat 202, and the rotation displacement wheel seat 202 is rotatably connected to a rotation displacement wheel 203.
[0035] In the implementation process of the present invention, first, the material to be conveyed is put into the conveying adjustment cylinder mechanism 5. At this time, the height adjustment mechanism 3 is turned on, so as to adjust the end conveying position of the conveying adjustment cylinder mechanism 5 to the specified height. At the same time, the deflection adjustment ring mechanism 4 is turned on, so as to adjust the deflection angle of the conveying adjustment cylinder mechanism 5. At this time, the rotation drive mechanism 6 is turned on, and the rotation drive mechanism 6 can drive the conveying adjustment cylinder mechanism 5, so as to drive the material in the conveying adjustment cylinder mechanism 5 to move, so as to realize the conveying of the material required by the molding machine. In addition, due to the existence of the adjustment scraping mechanism 9, the material attached to the inner wall of the conveying adjustment cylinder mechanism 5 can be scraped.
[0036] The present invention can adaptively adjust the height of the conveying and adjusting cylinder mechanism 5 by setting the height adjusting mechanism 3, can adjust the deflection angle of the conveying and adjusting cylinder mechanism 5 by the deflection adjusting ring mechanism 4, can drive the conveying and adjusting cylinder mechanism 5 by the rotation driving mechanism 6. In cooperation with the conveying and adjusting cylinder mechanism 5, it can convey and mix materials, and at the same time can heat-treat the materials. The two ends of the conveying and adjusting cylinder mechanism 5 can be blocked and adjusted by the end feeding and discharging mechanism 7, and the materials attached to the inner wall of the conveying and adjusting cylinder mechanism 5 can be effectively scraped off by the adjusting scraping mechanism 9, improving the feeding efficiency of the molding machine.
