[0026] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figures 1 to 8 The embodiments are described in detail.

[0027] This embodiment provides a feeding mechanism for a urea-formaldehyde toilet seat die-casting mold with quantitative feeding and heating, as shown in the attached Figure 1-8 As shown, it includes a movable placement rack 1 and a storage box 2 for storing raw materials. A movable support mechanism is arranged at the bottom of the placement rack 1. The movable support mechanism includes rollers 6 and legs 7 with threads. The number of rollers 6 and legs 7 is four. The four rollers 6 are rotatably connected to the four corners of the lower surface of the placement rack 1. The four legs 7 are rotatably connected to the four corners of the lower surface of the placement rack 1 through threads. When the placement rack 1 needs to be moved, the four legs 7 can be rotated to a position where the bottom ends are higher than the lower surface of the rollers 6. At this time, the four rollers 6 are in contact with the ground, which can facilitate the placement rack 1 to be pushed to other positions; when the position of the placement rack 1 needs to be fixed, the four legs 7 are rotated downward and the rollers 6 are pushed up to leave the ground. At this time, the legs 7 support the placement rack 1, which can prevent the placement rack 1 from moving back and forth and fix its position.

[0028] The storage box 2 is fixedly connected to the upper surface of the placement rack 1 and a discharge assembly is arranged at the bottom, the discharge assembly includes a discharge pipe 8 and a solenoid valve 9. The bottom of the storage box 2 is an inverted cone, which can make the raw materials in the storage box 2 fall smoothly from the discharge pipe 8. The discharge pipe 8 is fixedly installed in the middle of the lower surface of the storage box 2 and the solenoid valve 9 is fixedly installed on the side of the discharge pipe 8. The solenoid valve 9 can control the on and off of the discharge pipe 8, thereby controlling the supply of raw materials;

[0029] A weighing mechanism for weighing raw materials is provided below the storage box 2. The weighing mechanism includes a horizontal support platform 10 and an electronic weighing instrument 11. The horizontal support platform 10 is fixedly connected to the middle part of the upper surface of the support plate 3. The electronic weighing instrument 11 is fixedly installed on the upper surface of the horizontal support platform 10 and the middle part corresponds to the discharge pipe 8. The horizontal support platform 10 can ensure that the electronic weighing instrument 11 is placed in a horizontal state, so that the measurement result is more accurate and errors are avoided. The electronic weighing instrument 11 is an existing well-known technology, so it will not be elaborated on here. The raw materials discharged from the discharge pipe 8 fall on the electronic weighing instrument 11. The electronic weighing instrument 11 can measure the weight of the falling raw materials in real time and is electrically connected to an external controller. When the electronic weighing instrument 11 measures that the weight of the falling raw materials reaches the specified weight, the controller immediately controls the solenoid valve 9 to close the discharge pipe 8, so as to accurately control the weight of the discharged raw materials and facilitate the rapid discharge of the specified weight of raw materials.

[0030] A material-moving mechanism for pushing the raw materials is arranged on the top of the weighing mechanism, and the material-moving mechanism comprises a driving motor 12, a lead screw 13, a lead screw slider 14 and a material-moving rack 15. A fixed plate 16 is fixedly connected to one side of the top of the placement rack 1, the driving motor 12 is fixedly mounted on the side of the fixed plate 16, and the output end is penetrated through the side of the fixed plate 16 and is connected to the lead screw 13 through a spline, the lead screw 13 is rotatably connected between the placement rack 1 and the fixed plate 16, the lead screw slider 14 is connected to the outside of the lead screw 13 through a threaded transmission, and a connecting rod 17 is fixedly connected to the side, the material-moving rack 15 is fixedly connected to the end of the connecting rod 17 away from the lead screw slider 14 and is arranged above the electronic weighing instrument 11, the material-moving rack 15 is arranged above the electronic weighing instrument 11 and corresponds to the electronic weighing instrument 11, which can prevent the fallen raw materials from rolling off the electronic weighing instrument 11 Sub-weighing instrument 11, the bottom end of the material shifting frame 15 does not contact with the electronic weighing instrument 11, which can prevent the measurement of the electronic weighing instrument 11 from being affected. A limit rod 18 is arranged below the lead screw 13 and the limit rod 18 is fixedly connected between the placing frame 1 and the fixing plate 16. The bottom of the lead screw slider 14 is laterally slidably connected to the outside of the limit rod 18; the driving motor 12 drives the lead screw 13 to rotate and can drive the lead screw slider 14 to move laterally, thereby controlling the lateral displacement of the material shifting frame 15. When the electronic weighing instrument 11 measures that the weight of the raw material reaches the specified weight, the driving motor 12 runs through the lead screw 13 to drive the lead screw slider 14 and the material shifting frame 15 to move to the side close to the heating mechanism. The material shifting frame 15 can shift the raw material on the electronic weighing instrument 11 off and slide it along the unloading plate 5 into the barrel body 19, thereby realizing automatic material shifting;

[0031] The top of the placement rack 1 is fixedly connected with a support plate 3, and one side of the upper surface of the support plate 3 is fixedly connected with a bracket 4. A heating mechanism for heating the raw material is arranged on the side of the bracket 4 away from the weighing mechanism. The heating mechanism comprises a barrel 19, a heating belt 20, a circular bracket 21 and a heating rod 22.

The number of the heating belts 20 is several and the several heating belts 20 are all fixedly mounted on the outer surface of the barrel 19. The circular bracket 21 is fixedly connected to the bottom of the inner surface of the barrel 19. The number of the heating rods 22 is four and the four heating rods 22 are fixedly mounted on the upper surface of the circular bracket 21 in the form of a ring array. The heating belt 20 and the heating rod 22 can heat the raw material in the barrel 19 after being energized. The heating belt 20 and the heating rod 22 can be used together to make the raw material in the barrel 19 more evenly heated, so as to avoid different heating degrees of the raw material in different parts of the barrel 19 affecting the die-casting effect.

[0032] A blocking mechanism is provided at the bottom opening of the heating mechanism, and the blocking mechanism includes a blocking plate 24 and an electric telescopic rod 25. The blocking plate 24 is hinged to the bottom of the barrel body 19 through a hinge and can seal the bottom of the barrel body 19. The fixed rod body part of the electric telescopic rod 25 is rotatably connected to the lower surface of the connecting frame 23, and the movable end is rotatably connected to the side of the lower surface of the blocking plate 24 close to the hinged part. When the movable end of the electric telescopic rod 25 extends outward, the blocking plate 24 can be pushed to block the bottom of the barrel body 19. When the movable end of the electric telescopic rod 25 is retracted inward, the blocking plate 24 can be pulled in a vertical direction, so that the raw materials in the barrel body 19 are discharged;

[0033] A blanking plate 5 is fixedly connected to the upper surface of the bracket 4 and is arranged between the weighing mechanism and the heating mechanism. The top of the blanking plate 5 corresponds to the edge of the electronic weighing instrument 11 and its width is greater than the width of the material shifting rack 15. The bottom of the blanking plate 5 corresponds to the top of the barrel 19 and its width is less than the diameter of the top of the barrel 19. The blanking plate 5 is in an inclined state as a whole and can receive the raw materials shifted from the electronic weighing instrument 11 by the material shifting rack 15. Baffles are arranged on both sides of the blanking plate 5 to ensure that the raw materials slide along the blanking plate 5 into the barrel 19 below.

[0034] The feeding mechanism can be used in conjunction with the toilet cover die-casting mold 26 and the robot tooling 27. Figure 8 As shown, the movable end of the robot tooling 27 can move to the bottom of the barrel body 19, receive the raw materials in the barrel body 19 and transfer them to the die-casting mold 26, and then control the die-casting mold 26 to die-cast the raw materials into a toilet cover;

[0035] The solenoid valve 9, the electronic weighing instrument 11, the driving motor 12, the heating belt 20, the heating rod 22, the electric telescopic rod 25, the die-casting mold 26 and the robot tooling 27 are all electrically connected to the external control unit.

[0036] In summary, the quantitative feeding and heating urea-formaldehyde toilet seat cover die-casting mold feeding mechanism has the following steps:

[0037] 1. Store enough raw materials in the storage box 2. When the raw materials are needed, control the solenoid valve 9 to open, and the raw materials fall from the discharge pipe 8 to the electronic weighing instrument 11. The electronic weighing instrument 11 detects the weight of the raw materials in real time. When the required weight is reached, control the solenoid valve 9 to close;

[0038] 2. Then, the driving motor 12 and the lead screw 13 drive the material rack 15 to move horizontally, and the raw materials on the electronic weighing instrument 11 are removed, and the raw materials slide along the unloading plate 5 into the barrel 19;

[0039] 3. According to the state of the required raw materials, choose whether to control the heating belt 20 and the heating rod 22 to heat the raw materials. Finally, control the movable end of the electric telescopic rod 25 to retract and open the blocking plate 24, so that the raw materials fall into the container at the movable end of the robot tooling 27, and add the raw materials to the die-casting mold 26 through the robot tooling 27 for die-casting.
