[0033] It should be noted that the lower end of the guide ring 56 is concave, that is, the distance between the guide ring 56 and the crushing ball 57 gradually shortens from top to bottom, and the outer surface of the crushing ball 57 is fixedly connected with a number of semicircular protrusions, so that when the several raised protrusions rotate with the crushing ball 57, they can rely on friction to carry the material between the crushing ball 57 and the guide ring 56 to extrude and crush the material.

[0034] In this embodiment, the toner raw material input can be squeezed and crushed by the crushing balls 57 and the guide ring 56 in the feed barrel 51, so that the crushed raw material is preliminarily preheated by the heating wire 53 in the mounting ring 52 and introduced into the housing 2, thereby shortening the time required for heating and melting the raw material input into the housing 2 and improving the smoothness during extrusion.

[0035] Among them, the transmission member 59 includes two pulleys fixedly connected to the rotating shaft 58 and the end of the front extrusion screw 4 respectively. A transmission belt is provided on the outer side of the pulley, so that the rotating front extrusion screw 4 can drive the rotating shaft 58 to rotate synchronously through the pulley and the transmission belt.

A fixing groove adapted to the block 810 is provided on the outer surface of the push rod 7, and the retaining frame 83 is U-shaped, and the end of the retaining frame 83 close to the limiting rod 85 is U-shaped.

[0039] In this embodiment, the connecting plate 88 lowered by the rotating threaded rod 811 can respectively drive the retaining frame 83 and the stop block 810 to limit the cover plate 6, the support cylinder 81 and the discharge pipe 82. Therefore, when the connecting plate 88 is raised by rotating the threaded rod 811 in the opposite direction, the cover plate 6 can be slid open to clean the extrusion screw 4 in the casing 2 and replace the discharge pipe 82 of different specifications.

[0040] Among them, a threaded hole is provided on the connecting plate 88 and is located on the outside of the threaded rod 811, and the threaded hole is adapted to the thread on the outer surface of the threaded rod 811, so that the rotating threaded rod 811 can drive the connecting plate 88 to move forward and backward and up and down for adjustment. A fixing groove is provided on the outer surface of the push rod 7 and is adapted to the block 810. The push rod 7 is blocked and limited by the block 810 extending into the fixed groove. The blocking frame 83 is U-shaped, and the end of the blocking frame 83 close to the limit rod 85 is U-shaped, so that the downward moving blocking frame 83 can block the connecting block 84 inserted into the limit rod 85 after it conflicts with the limit rod 85, so as to be fixed to the connecting block 84 and the support tube 81.

[0041] In addition, the support member 8 also includes a group of guide blocks 86 fixedly connected to the side of the retaining frame 83 close to the casing 2.

[0042] In an optional embodiment, the upper end of the threaded rod 811 is fixedly connected to a rotating block 812 , and the rotating block 812 is slidably connected to an insertion rod 813 with one end passing through and extending into the interior of the housing 2 , and a retaining ring 814 is fixedly connected to the insertion rod 813 .

[0043] In this embodiment, the insertion rod 813 on the rotating block 812 is used to facilitate the operator to rotate the rotating block 812 and the screw rod 811, and the insertion rod 813 is inserted into the housing 2 to support and limit the screw rod 811.

[0044] It should be noted that the upper surface of the housing 2 is provided with a number of slots, which are equidistantly distributed in a circular shape with the threaded rod 811 as the center, and the specifications of the slots are compatible with the specifications of the insertion rod 813. The inner side of the slot is fixedly connected with a non-slip rubber ring, which limits the rotation of the threaded rod 811 and the rotating block 812 by inserting the insertion rod 813 into the slot. When the insertion rod 813 is pulled out of the slot, the rotating block 812 and the threaded rod 811 can be driven to rotate synchronously by rotating the insertion rod 813.

[0045] The working principle in the above embodiment is:

[0046] When the driven motor 3 is started and drives the two extrusion screws 4 to rotate, the rotating shaft 58 can be driven to rotate synchronously through the transmission member 59. The rotating rotating shaft 58 can drive the crushing ball 57 to rotate in the guide ring 56, and then drive the several protrusions on the crushing ball 57 to rotate with the crushing ball 57. The material is carried between the crushing ball 57 and the guide ring 56 by friction, so as to squeeze and crush the material put into the feed barrel 51. After the heating wire 53 is started to preheat the crushed material, the valve 54 can be opened to guide the material into the casing 2 through the guide pipe 55 and extruded out through the extrusion screw 4.

[0047] Since the connecting plate 88 lowered by the rotating threaded rod 811 can respectively drive the baffle 83 and the stop block 810 on the arc block 89 to respectively limit the push rod 7 on the cover 6 and the support cylinder 81 and the discharge pipe 82, when it is necessary to clean the inner wall of the casing 2 and the extrusion screw 4 or replace the discharge pipe 82 of different specifications, the connecting plate 88 can be raised by rotating the threaded rod 811 in the opposite direction, and the cover 6 can be pushed horizontally by the push rod 7 to slide open to clean the extrusion screw 4 in the casing 2. After the connecting block 84 on the support cover 81 is no longer blocked by the baffle 83, the support cover 81 and the discharge pipe 82 can be removed to replace the discharge pipe 82 of different specifications.

[0048] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
