[0019] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0021] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0022] An extruder is a machine that uses high pressure and high temperature to form powdered materials into desired shapes. The geometric shape of the inner cavity of the die determines the flow state of the molten plastic, thereby controlling the linear axisymmetry and nonlinear shape of the plastic material. The filter inside the die plays a key role in the shape of the extruded material.
[0023] However, the filter is prone to clogging after a long period of use, so it needs to be replaced frequently. However, since the filter is inside the machine head, the machine needs to be stopped for replacement, which affects production efficiency.
[0024] In order to solve the above problems, this embodiment discloses an extruder granulator head, whose structure is as follows: Figure 1 and Figure 2 As shown, the extruder granulation head includes a head body 100, a sliding plate 101 slidably arranged on the head body 100 and penetrating the interior of the head body 100, and a sliding drive member 102 arranged on one side of the head body 100 and used to drive the sliding plate 101 to slide, and a plurality of filter screens 103 arranged at intervals are arranged on the sliding plate 101.
[0025] Specifically, an extruder granulation head of the present embodiment is provided with a slidable sliding plate 101 on the head body 100, and a corresponding filter 103 is provided on the sliding plate 101. When the filter 103 is blocked, the sliding plate 101 is driven to slide by the sliding driving member 102, so that another filter 103 is aligned with the flow channel inside the head body 100, thereby realizing the screen changing operation; and the blocked filter 103 can be replaced at this time, effectively improving the production efficiency of the extruder.
[0026] Furthermore, the filter screen 103 is detachably connected to the sliding plate 101, and a through hole 104 adapted to the shape of the sliding plate 101 is provided on the other side of the die head body 100. In actual use, the filter screen 103 closest to the through hole 104 can be used, and when the impurities on the filter screen 103 plate accumulate to the pressure value set by the melt pressure sensor, the sliding drive member 102 pushes out the sliding plate 101 and replaces the clean filter screen 103. The blocked filter screen 103 extends from the through hole 104 along with one end of the sliding plate 101, so that the filter screen 103 can be conveniently replaced.
[0027] Furthermore, a heating device 105 and a temperature detection device 106 are also provided at the upper end of the die body 100. The temperature of the die can be adjusted by the heating device 105 and the temperature detection device 106 to ensure that the plastic liquid reaches a good melt state and fluidity, which is conducive to ensuring product quality and tensile properties.
[0028] Specifically, the feed end of the head body 100 is provided with a feed flange 107, and the feed flange 107 is provided with an 8-shaped hole 108 connected to the flow channel inside the head body 100; the discharge end of the head body 100 is provided with a discharge flange 109, and the feed flange 107 is provided with a plurality of elliptical holes 110 arranged at intervals and connected to the flow channel inside the head body 100.
[0029] Among them, the feed flange 107 is provided with a melt pressure sensor, which can detect the pressure at the filter 103. When the impurities in the filter 103 accumulate to the pressure value set by the melt pressure sensor, the sliding drive 102 starts to move, pulling out the dirty filter 103 and replacing it with a clean filter 103.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
