[0020] The present application discloses a transfer device for silicon nitride production. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4, including a support plate 1, the bottom of the support plate 1 is detachably fixedly connected to a walking wheel 25 by bolts, which is convenient for loading silicon nitride molded products through the support plate 1, and the walking wheel 25 facilitates the movement of the entire transfer device, thereby realizing the transfer and transportation of the silicon nitride molded products. The front end of the support plate 1 is connected to a handle 4, which is convenient for pulling the entire transfer device through the handle 4, thereby facilitating the transportation of silicon nitride molded products. Specifically, the front end of the support plate 1 is welded or detachably fixedly connected to a pair of fixed plates 2 by bolts, so that the two fixed plates 2 are connected to the support plate 1 together. The two ends of the handle 4 are welded or detachably fixedly connected to a fixed head 3 by bolts, so that the fixed head 3 is connected to the handle 4 together. The fixed head 3 is detachably connected to the fixed plate 2 by bolts, so that the fixed plate 2 and the fixed head 3 are connected together, thereby connecting the handle 4 to the support plate 1, which is convenient for pulling the entire transfer device to move by the handle 4.

[0021] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The support plate 1 is provided with a rotation groove 5, in which a plurality of rotating rollers 7 are rotatably connected via a connecting shaft 6, so that the rotating rollers 7 can rotate within the rotation groove 5 with the connecting shaft 6 as the axis. A connecting plate 23 is welded or detachably fixedly connected to the rotation groove 5 by bolts, and the connecting shaft 6 is rotatably connected to the connecting plate 23 via a bearing, so that the connecting plate 23 can support and limit the connecting shaft 6. The upper end surface of the rotating roller 7 protrudes from the rotation groove 5, so that when the silicon nitride molded product is placed on the support plate 1, it first contacts the rotating roller 7, and then the rotating roller 7 facilitates the movement of the silicon nitride molded product on the support plate 1, thereby facilitating the transfer of the silicon nitride molded product relative to the support plate 1.

[0022] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The outer end surface of the support plate 1 is provided with a connecting groove 8, and a lifting frame 9 is provided in the connecting groove 8. A lifting assembly for controlling the up and down movement of the lifting frame 9 is connected to the support plate 1, so that the lifting frame 9 can be ejected from the connecting groove 8 through the lifting assembly, so that the upper end surface of the lifting frame 9 exceeds the upper end surface of the rotating roller 7, so as to realize the separation of the silicon nitride molded product on the lifting frame 9 from the rotating roller 7. A plurality of lifting cross bars 24 are welded or detachably fixedly connected to the lifting frame 9 by bolts, and the lifting cross bars 24 are staggered with the rotating roller 7. When the lifting frame 9 is fully received in the connecting groove 8, the upper end surface of the rotating roller 7 exceeds the upper end surface of the lifting frame 9, so that the stability of the entire lifting frame 9 is increased by the lifting cross bars 24, and at the same time, the silicon nitride molded product can be better received, thereby facilitating the lifting of the silicon nitride molded product from the rotating roller 7.

[0023] Reference Figure 1、 Figure 2 、 Figure 3 、 Figure 4 The jacking assembly includes a jacking tooth plate 11, a jacking gear 14, a rotating shaft 13, a transmission shaft 19, a main bevel gear 17, and a slave bevel gear 20. A jacking hole 10 is provided in the connecting groove 8. One end of the jacking tooth plate 11 is connected to the jacking frame 9, and the other end extends to the bottom of the support plate 1 through the jacking hole 10, so that the jacking frame 9 and the jacking tooth plate 11 are connected together to achieve simultaneous movement, and then the jacking frame 9 is driven to move by the movement of the jacking tooth plate 11 located below the support plate 1. The rotating shafts 13 are arranged in pairs and are connected to the bottom surface of the support plate 1 through a plurality of first positioning plates 12. Specifically, the first positioning plates 12 are welded or detachably fixed to the bottom surface of the support plate 1 by bolts, so that the first positioning plates 12 are connected to the support plate 1 together. The rotating shaft 13 is rotatably connected to the first positioning plate 12 through a bearing, so that the rotating shaft 13 is supported and limited by the first positioning plate 12, so that the rotating shaft 13 is connected to the support plate 1, and at the same time, the bearing does not affect the rotation of the rotating shaft 13 relative to the support plate 1 and the first positioning plate 12. The jacking gear 14 and the main bevel gear 17 are detachably fixed to the rotating shaft 13 by bolts, so that the jacking gear 14 and the main bevel gear 17 are connected to the rotating shaft 13 to achieve simultaneous rotation. The jacking gear 14 is engaged with the jacking gear plate 11, so that the jacking gear 14 rotates and drives the jacking gear plate 11 to move along the jacking hole 10. When the jacking gear plate 11 moves upward, the silicon nitride molded product on the rotating roller 7 can be lifted upward to separate it from the rotating roller 7, so that the transfer device can stably transfer the silicon nitride molded product.

[0024] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The transmission shaft 19 is connected to the bottom surface of the support plate 1 through a plurality of second positioning plates 18. Specifically, the second positioning plates 18 are welded or removably fixed to the bottom surface of the support plate 1 by bolts, so that the second positioning plates 18 are connected to the support plate 1. The transmission shaft 19 is rotatably connected to the second positioning plates 18 through bearings, so that the second positioning plates 18 support and limit the transmission shaft 19, so that the transmission shaft 19 is connected to the support plate 1. At the same time, the bearings do not affect the rotation of the transmission shaft 19 relative to the support plate 1 and the second positioning plates 18. The transmission shaft 19 is located between the two rotating shafts 13, and the slave bevel gear 20 is detachably fixed to the transmission shaft 19 by bolts. The main bevel gear 17 is meshed with the slave bevel gear 20, so that the slave bevel gear 20 is connected to the transmission shaft 19 to achieve simultaneous rotation. The main bevel gear 17 is driven to rotate by the rotation of the rotating shaft 13, and the main bevel gear 17 drives the slave bevel gear 20 to rotate. The slave bevel gear 20 drives the transmission shaft 19 to rotate, thereby achieving the simultaneous rotation of the two rotating shafts 13, thereby being able to simultaneously drive multiple lifting gear plates 11 to move relative to the support plate 1.

[0025] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 A non-circular insertion hole 15 is provided at the end of the rotating shaft 13, and a crank 16 is inserted into the insertion hole 15, so that the crank 16 can be detachably connected to the rotating shaft 13 through the insertion hole 15, and then the rotating shaft 13 is driven to rotate by the crank 16, thereby controlling the up and down movement of the jacking frame 9. A positioning screw hole 21 is provided on the support plate 1, which is connected to the jacking hole 10. A positioning bolt 22 is connected to the inner thread of the positioning screw hole 21, so that by rotating the positioning bolt 22, the positioning bolt 22 can be used to position the jacking gear plate 11, preventing the jacking frame 9 from automatically moving relative to the support plate 1, thereby avoiding affecting the stability of the silicon nitride molded product during transportation.

[0026] When in use, first, the lifting frame 9 is raised by turning the handle 16, so that the lifting frame 9 is disengaged from the connecting groove 8, and the upper surface of the lifting frame 9 is higher than the rotating shaft 13, and then the processed silicon nitride molded product is placed on the support plate 1. At this time, the silicon nitride molded product is in conflict with the lifting frame 9 and the lifting cross bar 24, and then the handle 4 is pulled to move the entire transfer device to the required position. When the silicon nitride molded product is unloaded from the lifting frame 9, the handle 16 is turned to make the lifting frame 9 completely retract into the connecting groove 8. At this time, the silicon nitride molded product falls onto the rotating roller 7, and then the silicon nitride molded product is pushed to be disengaged from the support plate 1.

[0027] Unless otherwise specified, the device components involved in the above embodiments are all conventional device components, and the structural settings, working modes or control modes involved are all conventional settings, working modes or control modes in the art unless otherwise specified.
