[0017] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0018] Embodiment 1:

[0019] The high-speed 3D printer nozzle for manufacturing rubber materials proposed in this embodiment includes three components: a shell, a feeding assembly and a movable nozzle assembly. The shell is hollow and open at both ends, has a predetermined accommodation, and is provided with a corresponding accommodation chamber, which can perform corresponding load-bearing and position-limiting operations. The feeding assembly is placed in the hollow accommodation chamber of the shell, and is externally connected to a corresponding feeding pipe, which can perform corresponding spraying and conveying operations. The movable nozzle assembly is connected to the feeding assembly, passes through the shell, extends to the predetermined operating position of the shell, and is a multi-layer structure, which can perform corresponding glue spraying and self-cleaning operations. The feeding assembly includes two components: a radiator and a fan. The radiator is placed in the accommodation chamber of the shell, is hollow and has a predetermined operating length, and a thermal breaker is provided in the hollow chamber, which can perform corresponding feeding operations. The fan is placed in the accommodation chamber of the shell, and a predetermined operating distance is left between the fan and the radiator, which can perform corresponding air blowing and heat dissipation operations on the radiator. In the later operation process, excessive heat can be transferred out through the thermal breaker, and the heat can be further conducted through the radiator to achieve the purpose of temperature control. The fan can be used to cool the radiator to prevent the raw materials in the input pipeline from melting prematurely due to excessive temperature, which in turn prevents the subsequent raw materials from entering normally. The movable nozzle assembly includes two components: a heating block and a sliding nozzle. The heating block is connected to the radiator, has a predetermined operating size, and is provided with a chamber of the predetermined operating size. One end of the thermal breaker extends into the chamber of the heating block. The sliding nozzle is slidably connected to the heating block and can be slidably adjusted within a predetermined range along the inner wall surface of the chamber of the heating block. A corresponding connecting hole is provided at the predetermined operating position of the heating block, one end of which is connected to the chamber of the heating block and the other end is open. In the later operation process, the operating state of the connecting hole provided in the heating block can be controlled by sliding adjustment of the sliding nozzle.

[0020] Embodiment 2:

[0021] On the basis of the first embodiment, the connecting hole provided in the heating block is offset from the sliding track of the sliding nozzle, and the operating position height of the connecting hole is lower than the highest point of the operating position height of the sliding nozzle. In the later operation process, when the sliding nozzle is slid and adjusted along the inner wall of the heating block, the sliding nozzle can normally perform the spraying operation when it slides to the highest point in the operation direction. At this time, the connecting hole provided in the heating block is completely blocked, that is, the sliding nozzle can operate normally. When the sliding nozzle is slid and adjusted along the inner wall of the heating block and slides to the lowest point in the operation direction, the connecting hole provided in the heating block is completely exposed. At this time, the sliding nozzle cannot perform normal spraying operations, and corresponding external processing operations can be performed at the connecting hole. An open hole of a predetermined operating size is provided at the predetermined operating position of the heating block; the open hole passes through the heating block, and is open at both ends, and a predetermined operating distance is left between the connecting hole provided in the heating block. In a further preferred embodiment, a thermostat is provided in the open hole provided in the heating block to ensure that the temperature of the heating block is maintained within a predetermined range. The connecting hole is externally connected with a corresponding connecting pipe and an air pump, and corresponding gas delivery operations can be performed. In the later operation process, after the corresponding spraying operation is completed, the sliding nozzle slides downward along the inner wall of the heating block in the operation direction to the lowest point, and the connecting hole is completely exposed. Then the external air pump starts to operate, and the gas is sent in through the connecting pipe to flush the sliding nozzle after the operation is completed, so as to avoid the occurrence of residual glue powder on the sliding nozzle, which may cause the nozzle to be blocked. The connecting pipe can be made of corresponding high-temperature resistant materials. Each component in the present application can be driven by a corresponding motor.

[0022] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the present invention defined in the appended claims.
