Ring die pelleter

[0016] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0017] like figure 1 , figure 2 As shown, it includes a main shaft nesting structure 1, a box body 2, a transmission plate 3, a ring die 4, a gear, a coupling 6 and a main shaft safety locking structure 7, and the main shaft nesting structure 1 includes a main shaft 11 and a pressure roller 12 The pressure roller 12 is connected to one end of the main shaft 11 through the transmission disc 3; the main shaft 11 passes vertically and is fixed in the middle of the box body 2, and the other end is fixed on the box body 2 through the main shaft safety locking structure 7; The pressure roller 12 is fixed inside the ring die 4, and is connected with the transmission disc 3 through the pressure roller 12; the coupling 6 passes through vertically and is fixed on the lower part of the box body 2; the gear includes a large gear 51 and a pinion 52, The large gear 51 is set on the part of the main shaft 11 inside the box body 2, the pinion gear 52 is set on the part of the coupling 6 inside the box body 2, the big gear 51 and the small gear 52 mesh with each other; The sleeve is fixed on the main shaft 11; the transmission disc 3 is fixedly connected to the main shaft 11 by bolts.

[0018] like image 3 As shown, the main shaft safety locking structure 7 includes a safety pin seat and a safety pin 76, and the safety pin seat includes a front safety pin seat 73 and a rear safety pin seat 74; the front safety pin seat 73 is set on the main shaft 11 and be fixed on the box body 2; the rear safety pin seat 74 has a mounting hole, and the rear safety pin seat 74 is fixed at the end of the main shaft 11; the safety pin 76 is fixed in the mounting hole of the rear safety pin seat 74; the front safety pin seat 74 is fixed in the mounting hole; The safety pin seat 73 is fixed on the box body 2 by fastening screws; the rear safety pin seat 74 is fixed on the end of the main shaft 11 by a tensioning nut 75 .

[0019] The ring die granulator of the present invention adopts the nested structure of the main shaft to prolong the service life of the main shaft, which not only facilitates later maintenance and repair, but also saves costs and is conducive to large-scale promotion; the safety locking structure of the main shaft is added, and the use of double The multi-layer safety pin seat fixes the main shaft, which effectively prevents the potential safety hazard caused by the violent vibration caused by the rapid rotation of the main shaft, provides safety protection for the operators, and is convenient for disassembly and later maintenance of the main shaft of the ring die granulator, which greatly improves the ring die granulator. The safety and practicality of the molding pellet machine.

[0020] The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still understand the foregoing embodiments The recorded technical solutions are modified, or some of the technical features are equivalently replaced. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
