DETAILED DESCRIPTION

[0026] The utility model will be further described below in connection with the drawings and examples;

[0027] As Figure 1 , Figure 2 and Figure 3As shown in the figure, a PEEK artificial bone dispensing device comprises a dispensing tank 1, a top cover 11 installed on the top of the dispensing tank 1, and a variable mixing mechanism installed inside the dispensing tank 1; the variable mixing mechanism comprises a first servo motor 2 installed on the top of the top cover 11, a fixed cylinder 21 fixed on the output end of the first servo motor 2 inside the dispensing tank 1, and a second servo motor 22 installed inside the fixed cylinder 21; the output end of the second servo motor 22 at the bottom of the fixed cylinder 21 is provided with a reciprocating screw rod 23; the side of the reciprocating screw rod 23 is threadedly connected with a moving ring 24, the side of the moving ring 24 is fixed with a plurality of stirring blades 25, and the moving ring 24 and the fixed cylinder 21 are provided with a support limiting assembly for limiting the rotation direction of the moving ring 24.

[0028] It should be noted that the side of the reciprocating screw rod 23 close to the top end is rotatably connected with the inner side of the fixed cylinder 21 through a bearing, the plurality of stirring blades 25 are evenly distributed in the side of the moving ring 24, and the fixed cylinder 21, the reciprocating screw rod 23 and the moving ring 24 are coaxially arranged; after adding raw materials such as PEEK resin, additives and coating materials into the dispensing tank 1, the first servo motor 2 is started to drive the fixed cylinder 21 inside the dispensing tank 1 to rotate, so that it can drive the plurality of stirring blades 25 at the bottom to rotate synchronously, and at the same time, the second servo motor 22 inside the fixed cylinder 21 is started to drive the reciprocating screw rod 23 to rotate, and the rotation direction of the moving ring 24 is limited through the cooperation of the support limiting assembly, and since the inner side of the moving ring 24 is threadedly connected with the side of the reciprocating screw rod 23, when the reciprocating screw rod 23 rotates, the moving ring 24 and the plurality of stirring blades 25 on the side can be driven to reciprocally move up and down along the side of the reciprocating screw rod 23, so that the plurality of stirring blades 25 can perform linear upward and downward movement and also perform rotary movement in the viscous mixed liquid of the PEEK resin, thereby breaking the stratification phenomenon, increasing the relative movement between the stirring blades 25 and the raw materials, enhancing the shearing effect, and quickly and effectively achieving the mixing uniformity of the raw materials.

[0029] As shown in the figure, Figure 3 In some embodiments, the support limiting assembly comprises a plurality of first struts 3 hinged at the bottom of the fixed cylinder 21 and a plurality of second struts 31 hinged at the top of the moving ring 24; the bottom end of the first struts 3 is hinged with the top end of the second struts 31.

[0030] It should be noted that the number of first support rods 3 and second support rods 31 is the same, and they are evenly distributed circumferentially on the side of the reciprocating screw 23. When the reciprocating screw 23 rotates, the rotation direction of the moving ring 24 can be restricted by the hinged cooperation between the first support rods 3 hinged to the bottom of the fixed cylinder 21 and the second support rods 31 hinged to the top of the moving ring 24. Thus, the moving ring 24 can achieve linear motion under the rotation of the reciprocating screw 23. The first support rods 3 and second support rods 31 flip outward at the hinge point, thereby ensuring the reliability of connection and limiting.

[0031] In some embodiments, a limiting block 4 is fixed at the bottom end of the reciprocating screw 23 to limit the linear direction of the moving ring 24; by setting the limiting block 4, the moving ring 24 can be limited in the direction of the bottom end of the reciprocating screw 23, thus preventing the moving ring 24 from deviating from its path.

[0032] like Figure 1 and Figure 2 As shown, in some embodiments, a feed pipe 5 and a liquid inlet pipe 51 are fixed to the top of the top cover 11, and the interiors of the feed pipe 5 and the liquid inlet pipe 51 extend to the lower surface of the top cover 11. Through the feed pipe 5, solid raw materials can be added to the interior of the mixing tank 1, and through the liquid inlet pipe 51, liquid raw materials can be added to the interior of the mixing tank 1.

[0033] In some embodiments, a discharge cylinder 6 is fixed to the bottom of the mixing tank 1, the interior of the discharge cylinder 6 extends into the interior of the mixing tank 1, and a valve 61 is installed on the side of the discharge cylinder 6; after the raw materials are mixed, the valve 61 is opened to discharge the mixed raw materials through the discharge cylinder 6.

[0034] like Figure 1 As shown, in some embodiments, a pressure gauge 7 for monitoring the internal pressure value of the mixing tank 1 is installed on the side of the mixing tank 1; the setting of the pressure gauge 7 facilitates the monitoring of the internal pressure condition of the mixing tank 1.

[0035] In some embodiments, an observation window 8 is provided on the side of the mixing tank 1 for observing the internal condition of the mixing tank 1; the observation window 8 facilitates observation of the internal condition of the mixing tank 1.

[0036] like Figure 1 As shown, in some embodiments, a base plate 9 is provided at the bottom of the mixing tank 1, and a plurality of support legs 91 are fixed at the top of the base plate 9. One side of the plurality of support legs 91 is fixed to the side of the mixing tank 1. The base plate 9 and the plurality of support legs 91 can provide stable support for the mixing tank 1.

[0037] In use, raw materials such as PEEK resin, additives, and coating materials are added to the inside of the mixing tank 1 through the feed pipe 5 and the liquid inlet pipe 51, respectively. The first servo motor 2 is started, driving the fixed cylinder 21 inside the mixing tank 1 to rotate, which in turn drives the several stirring blades 25 at the bottom to rotate synchronously. At the same time, the second servo motor 22 inside the fixed cylinder 21 is started, driving the reciprocating screw 23 to rotate. The rotation direction of the moving ring 24 is restricted by the hinged limiting of several first support rods 3 and several second support rods 31. Since the inner side of the moving ring 24 is screwed to the side of the reciprocating screw 23, the rotation direction of the moving ring 24 is restricted. The reciprocating screw 23 is connected in a spiral pattern, so that when the reciprocating screw 23 rotates, it can drive the moving ring 24 and several stirring blades 25 on the side to move back and forth along the side of the reciprocating screw 23. This allows the stirring blades 25 to move up and down in a straight line and rotate in the viscous mixture of PEEK resin, thereby breaking the stratification phenomenon and generating more relative motion between the stirring blades 25 and the raw materials, enhancing the shearing effect and quickly and effectively achieving the uniformity of the mixing. After the mixing of the raw materials is completed, the valve 61 is opened to discharge the mixed raw materials through the discharge cylinder 6.
