When the cargo plate 20 carries the shell 90 and rotates, it will contact the roller 11 one by one, and rely on the friction between the roller 11 and the shell 90 to drive the shell 90 to rotate, thereby improving the uniformity of heating of the shell 90, and thus the annealing quality of the shell 90 can be improved.

[0041] In some embodiments, as Figure 6 and Figure 7As shown, the loading device 40 includes a baffle 41, a base plate 42, a discharge plate 44, a telescopic drive assembly 45 and two belt conveyor assemblies 43 arranged parallel to each other, the two groups of belt conveyor assemblies 43 are arranged above the base plate 42, the baffle 41 is arranged at one end above the base plate 42, the two groups of belt conveyor assemblies 43, the base plate 42 and the baffle 41 constitute a chamber for accommodating the shell 90 to be annealed, and this chamber can accommodate multiple shells 90 distributed side by side, wherein the base plate 42 is provided with a discharge hole, the telescopic drive assembly 45 and the discharge plate 44 are located below the base plate 42, the telescopic drive assembly 45 and the discharge plate 44 are connected, and the telescopic drive assembly 45 is used to drive the discharge plate 44 to close or open the discharge hole.

The air pipe is connected to a high-speed airflow control valve for providing a pulse air source; the discharge belt assembly 80 is located below the cargo tray 20. The discharge belt assembly 80 is used to transport the shell 90 unloaded from the cargo tray 20. The discharge belt assembly 80 includes a belt and baffles 41 arranged on both sides of the belt.

[0046] In some embodiments, the rotary drive device includes a dividing cam mechanism, which is used to drive the positioning plate 20 and the cargo plate 20 to perform indexing rotation; the rotary drive device 60 includes a drive motor 61 and a transmission assembly 62, and the drive motor 61 is arranged on the fixed plate 10, wherein a mounting plate protruding outward can be provided on the outer side of the fixed plate 10, and a mounting hole 14 is provided on the mounting plate.

In order to improve the connection stability of the copper busbar 51, a plurality of mounting seats 15 distributed along the circumferential direction are provided on the fixing plate 10. The copper busbar 51 is connected to the mounting seats 15. The copper busbar 51 is distributed in an arc shape, and the mounting seats 15 are provided with an avoidance channel for the shell 90 to pass through. In addition, in order to improve the level of automation, a control device can also be provided. The control device is electrically connected to the rotary drive device, the pressing device 100, the rotary drive device 60, the telescopic drive assembly 45, the belt conveyor assembly 43, the heating device 50, the nozzle 70, and the unloading belt assembly 80 to control the loading, transferring, heating, and unloading actions of the entire device.

[0048] The working principle of the shell mouth annealing device provided in the embodiment of the utility model is as follows:

[0049] The shells 90 to be annealed are placed on the positioning seats 21 on the loading tray 20 by the loading device 40. Multiple shells 90 can be placed side by side between the two sets of belt conveyor assemblies 43 of the loading device 40. During loading, the shells 90 can be first conveyed to the discharge port, and then pressed into the positioning seats 21 by the pressing device 100.

[0050] The rotary drive device controls the positioning plate 20 and the cargo tray 20 to rotate at a preset angle so that the housing 90 is located at the heating device 50. At this time, the vacant positioning seat 21 on the cargo tray 20 can be loaded through step 1.

[0051] The heating device 50 is started to heat the housing 90. The heating can be performed by energizing the electromagnetic induction coil.

[0052] The roller 11 is driven to rotate by the rotary drive device 60, and the housing 90 is rotated by the friction between the roller 11 and the housing 90. The rotation of the housing 90 can improve the uniformity of the heating of the housing 90.

[0053] The rotary drive device controls the positioning plate 20 and the cargo tray 20 to rotate to a preset angle so as to cool naturally after being separated from the heating device 50 and rotate to the unloading position.

[0054] When the annealed shell 90 is rotated to the unloading position, high-pressure air is blown through the jet hole to blow the shell 90 away from the positioning seat 21. Then, under the action of the rotational force of the positioning plate 20 and the cargo plate 20, the shell 90 can fall from the loading and unloading gap 12 onto the unloading belt assembly 80.

[0055] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0056] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
