Utility Model Content

[0005] In order to improve the uniformity of feeding, the present application provides a plastic extruder with uniform feeding.

[0006] The present application provides a plastic extruder with uniform feeding, which adopts the following technical solution:

[0007] A plastic extruder with uniform feeding comprises a machine body, wherein the machine body is provided with a discharge port and a feed port, a feed barrel is fixed at the feed port, a dispersion disk is slidably arranged in the feed barrel, and a plurality of dispersion holes are provided on the dispersion disk.

[0008] By adopting the above technical scheme, a dispersion disk is slidably arranged in the feed barrel, and a plurality of dispersion holes are opened on the dispersion disk. After the raw materials are placed in the feed barrel, the raw materials slide in the feed barrel along the axis direction of the feed barrel together with the dispersion disk under the driving action of the dispersion disk, thereby shaking off the agglomerated raw materials. The shaken raw materials can enter the interior of the machine body through the dispersion disk, thereby improving the uniformity of the machine body feeding and facilitating the processing process.

[0009] Optionally, a positioning ring is detachably connected to the inner wall of the feed barrel, the inner wall diameter of the positioning ring is larger than the outer wall diameter of the dispersion disk, and a flexible member is fixed between the positioning ring and the dispersion disk.

[0010] By adopting the above technical solution, the inner wall diameter of the positioning ring is larger than the outer wall diameter of the dispersion disk, and a flexible part is fixed between the positioning ring and the dispersion disk. Under the action of the flexible part, the positioning ring is connected to the dispersion disk. At the same time, since it is a flexible part, relative movement can occur between the positioning ring and the dispersion disk, which facilitates the movement process of the dispersion disk.

[0011] Optionally, the flexible member is made of rubber.

[0012] By adopting the above technical solution, the flexible member is made of rubber material, which ensures the stability of the connection between the positioning ring and the dispersion disk while not affecting the movement of the dispersion disk.

[0013] Optionally, a control motor is fixed to the inner wall of the feed barrel, a control cam is fixed to the rotating shaft of the control motor, and a side wall of the control cam abuts against the bottom of the dispersion disk.

[0014] By adopting the above technical solution, a control cam is fixed at the rotating shaft of the control motor, and the side wall of the control cam abuts against the bottom of the dispersion disk. The rotation of the control motor drives the control cam to rotate, and the rotation of the control cam drives the dispersion disk to move. At the same time, the dispersion disk itself has gravity. Therefore, during the movement of the control cam, the dispersion disk can reciprocate in the feed barrel along the axial direction of the feed barrel.

[0015] Optionally, a support ring is fixed to the inner wall of the feed barrel, and the diameter of the inner wall of the support ring is larger than the diameter of the inner wall of the positioning ring and smaller than the diameter of the outer wall of the positioning ring.

[0016] By adopting the above technical solution, the inner wall diameter of the support ring is larger than the inner wall diameter of the positioning ring and smaller than the outer wall diameter of the positioning ring, which makes it easy for the positioning ring to abut against the end face of the support ring during installation. The support ring provides support for the positioning ring, thereby facilitating the positioning of the positioning ring.

[0017] Optionally, a plurality of connection holes are provided on the side wall of the feed barrel, and connection bolts are detachably connected in the connection holes. The positioning ring is provided with mounting holes for passing the connection bolts.

[0018] By adopting the above technical solution, a connecting bolt is detachably connected in the connecting hole, and a mounting hole for passing the connecting bolt is opened on the positioning ring. Therefore, the connecting bolt is passed through the connecting hole and the mounting hole at the same time, which is convenient for fixing the position of the positioning ring and reduces the possibility of displacement of the positioning ring.

[0019] Optionally, a disengagement guide surface is provided on the side wall of the positioning ring facing away from the supporting ring.

[0020] By adopting the above technical solution, a disengagement guide surface is provided on the side wall of the positioning ring away from the support ring, and the disengagement guide surface is inclined, which reduces the possibility of raw materials accumulating on the positioning ring and facilitates the loading process.

[0021] Optionally, a mounting groove is provided on the side wall of the feed barrel, a mounting plate for closing the mounting groove is rotatably provided on the inner side wall of the mounting groove, and the control motor is fixed to the mounting plate.

[0022] By adopting the above technical solution, the control motor is installed on the mounting plate, and the control motor can be driven to move to the inside of the feed barrel or transferred to the outside of the feed barrel by rotating the mounting plate, which is convenient for the maintenance of the control motor.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. A dispersion plate is slidably arranged in the feed barrel, and a number of dispersion holes are opened on the dispersion plate. After the raw materials are placed in the feed barrel, the raw materials slide along the axis direction of the feed barrel together with the dispersion plate under the driving action of the dispersion plate, thereby shaking off the agglomerated raw materials. The shaken raw materials can enter the body through the dispersion plate, thereby improving the uniformity of the body feeding and facilitating the processing process;

[0025] 2. A control cam is fixed at the rotating shaft of the control motor, and the side wall of the control cam abuts against the bottom of the dispersion disk. The rotation of the control motor drives the control cam to rotate, and the rotation of the control cam drives the dispersion disk to move. At the same time, the dispersion disk itself has gravity. Therefore, during the movement of the control cam, the dispersion disk can reciprocate in the feed barrel along the axis direction of the feed barrel. BRIEF DESCRIPTION OF THE DRAWINGS
