[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Refer to Figure 1 and Figure 4 As shown in [drawings not specified in the original], an embodiment provided by the present invention: A servo extrusion device includes: a barrel 1 for storing raw materials, a feed pipe 2 is provided on the right side of the lower end of the barrel 1, a discharge port 3 is provided at the bottom of the barrel 1, ducts 16 are provided on both the right side and the lower side of the barrel 1, springs 17 are provided inside the ducts 16, plug balls 18 are provided at the ends of the springs 17, limit blocks 19 are provided at the tops of the ducts 16, and a fixed cylinder 20 is provided jointly outside the limit blocks 19 and the ducts 16. The left end of the right duct 16 is fixedly connected to the inside of the lower end of the barrel 1, the right end of the right fixed cylinder 20 is fixedly connected to the left end of the feed pipe 2, the bottom of the lower duct 16 is fixedly connected to the top of the discharge port 3, and the top of the lower fixed cylinder 20 is fixedly connected to the bottom of the barrel 1.

[0027] The provided spring 17 can push the plug ball 18 into contact with the limit block 19 to block the raw material passage. When taking materials, the plug ball 18 on the right compresses the spring 17 and separates from the limit block 19, and the raw materials enter through the bearing 12, pass through the duct 16 and enter the barrel 1. At this time, the spring 17 on the lower side pushes the plug ball 18 into contact with the limit block 19 on the lower side to block the raw material passage on the lower side. When extruding the raw materials, the spring 17 on the right pushes the plug ball 18 into contact with the limit block 19 to block the raw material passage, and the plug ball 18 on the lower side is subjected to pressure and compresses the spring 17 on the lower side, so that the raw materials in the barrel 1 are extruded from the discharge port 3 for coating. The ducts 16 and the fixed cylinders 20 are threadedly connected, and by rotating, the ducts 16 can be separated from the fixed cylinders 20, and the inside of the one-way valve can be cleaned to avoid blockage.

[0028] Refer to Figure 1 - Figure 3, the mounting plate 4 serving as a load-bearing structure has an internal thread wheel 5 provided at its right end. A screw rod 6 is threadedly connected to the middle of the internal thread wheel 5. The bottom of the screw rod 6 is fixedly connected to a piston 7. The outer wall of the piston 7 is movably connected inside the material bucket 1. Inside the right end of the mounting plate 4, a guiding cover 8 is fixedly connected. In the middle of the bottom end of the guiding cover 8, a guiding hole 9 is provided. The screw rod 6 is movably connected inside the guiding hole 9. On the upper side of the right end of the mounting plate 4, a fixing cover 10 is provided. At both ends of the fixing cover 10, fixing rods 11 are fixedly connected respectively. The lower ends of the fixing rods 11 are fixedly connected to the upper side of the mounting plate 4 respectively. Bearings 12 are fixedly connected inside both the fixing cover 10 and the guiding cover 8. The inner rings of the bearings 12 are fixedly connected with connecting rings 13. The opposite ends of the connecting rings 13 are fixedly connected to the outside of the internal thread wheel 5 respectively. At the lower left side of the left end of the mounting plate 4, a motor 14 is fixedly connected. The driving shaft of the motor 14 is fixedly connected with a pulley 15. The pulley 15 is connected to the outside of the internal thread wheel 5 through a belt.

[0029] The provided guiding cover 8 and fixing cover 10 can fix the two bearings 12. The provided internal thread wheel 5 can rotate through the connecting rings 13 and bearings 12. The guiding hole 9 provided at the bottom of the guiding cover 8 can restrict the screw rod 6 to prevent the screw rod 6 from rotating. When taking materials, start the motor 14 to rotate forward, and drive the pulley 15 to rotate. The pulley 15 drives the internal thread wheel 5 to rotate forward in cooperation with the belt. The rotating internal thread wheel 5 cooperates with the screw rod 6 to drive the piston 7 to move upward. At this time, the plug ball 18 on the right side is under pressure and compresses the spring 17 on the right side to the left. The plug ball 18 on the right side separates from the limit block 19, and the raw material passes through the conduit 16 and enters the inside of the material bucket 1 to complete the material taking. When discharging materials, start the motor 14 to drive the pulley 15 to rotate in reverse, and drive the internal thread wheel 5 to rotate in reverse through the belt, so that the screw rod 6 and the piston 7 move downward. At this time, the plug ball 18 on the right side remains stationary, and the plug ball 18 on the lower side is under pressure and compresses the spring 17 downward. The plug ball 18 separates from the limit block 19, and the raw material passes through the conduit 16 on the lower side and is extruded from the discharge port 3 for smearing. It replaces the traditional pneumatic extrusion of raw materials, avoids being affected by factors such as air pressure, temperature, material viscosity, and changes in the cross-section of the discharge path, can maintain a stable output of materials, and can accurately control the feeding speed.

[0030] Working principle: Taking materials, start the motor 14 to rotate forward, drive the pulley 15 to rotate, drive the internal thread wheel 5 to rotate through the pulley 15 and the belt. The rotating internal thread wheel 5 can drive the screw rod 6 and the piston 7 to move upward. At this time, the raw material enters the material bucket 1 from the one-way valve and the feed pipe 2 on the right side. Extruding, start the motor 14 to rotate in reverse, thereby driving the pulley 15 to rotate, driving the internal thread wheel 5 to rotate in reverse through the pulley 15 and the belt, and making the screw rod 6 and the piston 7 descend, and extrude the raw material from the one-way valve and the discharge port 3 at the lower side of the material bucket 1 for smearing.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
