Thus, a feature identified with "first," "second," etc., may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.
[0022] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0023] In this application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.
[0024] See also Figure 1As shown, one embodiment of the present application provides a plastic extruder with an adjustable main unit position. Specifically, the plastic extruder includes a frame 19, a base plate 1, a motor 2, a main unit 3, a barrel 4, and a position adjustment and calibration mechanism. The main unit 3 of the extruder is mounted on the position adjustment mechanism, and the adjustment and calibration mechanism is connected to the base plate 1.
[0025] See also Figure 1 、 2 3. The position adjustment and calibration mechanism includes a base plate 1, a longitudinal movable plate 5, and a transverse movable plate 6. The base plate 1 is fixedly mounted on a frame 19. Two parallel longitudinal slide rails 12 are formed on the upper surface of the base plate 1. A pair of longitudinal movable sliders 18 are slidably connected to the longitudinal slide rails 12. The longitudinal movable plate 5 is fixedly mounted above the pair of longitudinal movable sliders 18 via bolts. When the longitudinal movable sliders 18 move, they can drive the longitudinal movable plate 5 to move as well.
[0026] The upper surface of the longitudinal movable plate 5 is formed with two parallel transverse grooves 11, which are perpendicular to the longitudinal guide rails 12. A transverse movable slider 10 is slidably mounted within the transverse grooves 11 and bolted to the lower surface of the transverse movable plate 6. The main unit 3 is bolted to the transverse movable plate 6. The transverse movable slider 10 drives the transverse movable plate 6 to move, which in turn drives the main unit 3 to move laterally. The position adjustment and calibration mechanism adjusts the position of the main unit 3 by adjusting the longitudinal movable plate 5 and the transverse movable plate 6.
[0027] To ensure that the position of the main unit 3 does not shift when it moves laterally, the widths of the laterally movable slider 10 and the laterally movable groove 11 are substantially the same.
[0028] See also Figure 4 、 5 The base plate 1 is provided with fastening block mounting holes 17. Four fastening blocks 7 are fixedly mounted on the base plate 1 via bolts passing through the fastening block mounting holes 17. Longitudinal fastening bolts 8 are rotatably mounted on the fastening blocks 7 at the front and rear ends of the longitudinal movable plate 5. Once the longitudinal position is determined, the longitudinal fastening bolts 8 can be tightened. The longitudinal fastening bolts 8 press the longitudinal movable plate 5 forward and backward, securing the longitudinal movable plate 5. The fastening block mounting holes 17 are also recessed relative to the base plate 1. This recessed design further ensures that the fastening blocks 7 are fixed in position while being bolted in place.
[0029] The distance between the front and rear fastening blocks 7 is the maximum spacing of the longitudinal movement of the extruder main unit 3. The width of the longitudinal slide rail 12 is roughly the same as the width of the longitudinal slider 12, ensuring that the position of the main unit 3 will not shift when the longitudinal slider 12 moves in the longitudinal slide rail 12.
[0030] A transverse moving plate fastening hole 13 is provided above the transverse moving plate 6. The transverse moving plate fastening hole 13 is an oblong hole extending laterally. The transverse moving plate 6 and the longitudinal moving plate 5 are movably connected by a first pin 14 inserted into the transverse moving plate fastening hole 13, so that the transverse moving plate 6 can be driven to move when the longitudinal moving plate 5 moves. Space is left on the left and right sides of the transverse moving plate fastening hole 13 to provide moving space for the subsequent movement of the transverse moving plate 6.
[0031] The longitudinal movable plate 5 is provided with a longitudinally extending oblong hole 15 , which serves to connect the longitudinal movable plate 5 to the base plate 1 . A second latch 16 is disposed within the longitudinal movable plate fastening hole 15 , enabling the movable connection between the longitudinal movable plate 5 and the base plate 1 . Space is left longitudinally in front of and behind the longitudinal movable plate fastening hole 15 to allow for subsequent movement of the longitudinal movable plate 5 and prevent lateral displacement of the longitudinal movable plate 5 .
[0032] Working principle: First, fix the main machine 3 on the transverse movable plate 6, then manually push the main machine 3 forward, backward, left and right to adjust the position, then tighten the longitudinal fastening bolts 8 and transverse fastening bolts 9, and the approximate position is determined. Then make more detailed adjustments and calibrations to the position of the main machine 3. The adjustment and calibration process can be roughly divided into the following four cases. The first case: when the main machine 3 is in the front position, continue to screw in the front longitudinal fastening bolts 8, and slowly unscrew the rear longitudinal fastening bolts 8. After determining that the front and rear positions have reached the correct position, tighten the front and rear longitudinal fastening bolts 8 at the same time to fix the front and rear positions of the main machine 3; the second case: when the main machine 3 is in the front position, continue to screw in the rear longitudinal fastening bolts 8, and slowly unscrew the front longitudinal fastening bolts 8. After determining that the front and rear positions have reached the correct position, tighten the front and rear longitudinal fastening bolts 8 at the same time to fix the main machine 3. The front and rear positions are fixed; the third case: when the main machine 3 is positioned to the left, the left side transverse fastening bolt 9 continues to be screwed in, and the right side transverse fastening bolt 9 is slowly unscrewed. After determining that the left and right positions have reached the correct positions, the left and right transverse fastening bolts 9 are tightened at the same time to fix the left and right positions of the main machine 3; the fourth case: when the main machine 3 is positioned to the right, the right side transverse fastening bolt 9 continues to be screwed in, and the left side transverse fastening bolt 9 is slowly unscrewed. After determining that the left and right positions have reached the correct positions, the left and right transverse fastening bolts 9 are tightened at the same time to fix the left and right positions of the main machine 3.
[0033] The utility model improves the efficiency and accuracy of the position adjustment of the host 3, can reduce the resistance encountered when pushing the host 3, helps the installer to determine the position of the host 3 more quickly, can make more detailed adjustments and calibrations to the position of the host 3, and ensures the accuracy and stability of the position of the host 3.
