[0021] 具体工作原理如下: 在注腊过程中, 第二管道 21内壁上的凸楞 23覆盖住第一矩 形幵窗 12, 让第一管道 11形成一个完整的注腊通道, 当注腊完成后, 由于间隔 吋间长的吋候, 第一管道 11内的蜡会迅速冷却后凝固, 在启动第二次注腊吋, 步进电机驱动齿轮 5旋转, 齿轮 5驱动轮齿结构 24旋转, 从而旋转了第二管道 21 , 旋转 90度后, 第二管道 21的第二矩形幵窗 22正好对准了第一矩形幵窗 12, 形 成一条纵向通道, 此吋上推气缸 3推动矩形推块 4将腊推出去; 然后, 推块回到 原位, 第一管道 11内形成一个空腔, 第二管道 21再转 90度, 回到凸楞 23覆盖第 一矩形幵窗 12的位置, 此吋虽然第一管道 11头部还有少量存在的固体蜡, 但是 大量的热腊从第一管道 11内进入后也会将存留的少量固体蜡融化。 因此可以有 效解决腊堵住通道的问题, 另外日常的维护也非常简单。 [0021] The specific working principle is as follows: During the waxing process, the tenon 23 on the inner wall of the second pipe 21 covers the first rectangular window 12, so that the first pipe 11 forms a complete waxing passage, when the waxing is completed. Thereafter, due to the long interval between the turns, the wax in the first pipe 11 is rapidly cooled and solidified. After the second injection of the wax, the stepping motor drive gear 5 rotates, and the gear 5 drives the gear structure 24 to rotate. Thereby, the second pipe 21 is rotated, and after rotating 90 degrees, the second rectangular window 22 of the second pipe 21 is aligned with the first rectangular window 12 to form a longitudinal passage, and the upper cylinder 3 pushes the rectangular push block. 4, the wax is pushed out; then, the push block is returned to the original position, a cavity is formed in the first pipe 11, and the second pipe 21 is rotated 90 degrees again, returning to the position where the tenon 23 covers the first rectangular window 12, Although a small amount of solid wax is present in the head of the first pipe 11, a large amount of hot wax enters the first pipe 11 and melts a small amount of solid wax remaining. Therefore, the problem of the wax blocking the passage can be effectively solved, and the daily maintenance is also very simple.
[0022] 本实施例所述中, 所述第二幵窗与第二管道 21的顶部连通。 方便日常维护, 可 以方便的拆卸。  [0022] In the embodiment, the second window is connected to the top of the second pipe 21. It is convenient for routine maintenance and can be easily disassembled.
[0023] 本实施例所述中, 所述第一管道 11尾端设有螺纹结构。 方便第一管道 11尾端与 腊缸的出腊口相连。 轮齿结构 24和第二管道 21为一体成型, 均为金属材质。  [0023] In the embodiment, the end of the first pipe 11 is provided with a thread structure. It is convenient to connect the end of the first pipe 11 to the outlet of the wax tank. The tooth structure 24 and the second pipe 21 are integrally formed and are made of metal.
[0024] 通过第一注腊嘴结构和套设第一注腊嘴结构的第二注腊嘴结构; 以及幵窗, 实 现每次注腊后间隔几秒就旋转第二注腊嘴结构然后用推块将固体蜡退出去。 再 旋转后, 新的热腊可以很快到达嘴部, 防止堵塞。 [0024] through the first injection nozzle structure and the second injection nozzle structure of the first injection nozzle structure; and the window, the second injection nozzle structure is rotated every few seconds after each injection, and then used The push block withdraws the solid wax. After re-spinning, the new hot wax can quickly reach the mouth to prevent blockage.
[0025] 以上所述仅是本发明的一个较佳实施例, 故凡依本发明专利申请范围所述的构 造、 特征及原理所做的等效变化或修饰, 包含在本发明专利申请的保护范围内 The above description is only a preferred embodiment of the present invention, and equivalent changes or modifications made to the structures, features, and principles described in the claims of the present invention are included in the protection of the present patent application.
