[0015] Beneficial effects:

[0016] 1.

[0017] 2. By arranging the guiding opening on the hemispherical shell and the discharging opening on the sector plate, the feeding guiding assembly can not only block the feeding cylinder to stop feeding, but also reduce the blockage of the raw materials and disperse the moving path of the raw materials when the feeding cylinder is feeding without blocking the discharging opening, reducing the influence of the valve structure of the feeding cylinder on the discharging.

[0018] 3. By setting up the material blocking component, the adaptability to powdery raw materials and filamentous raw materials is improved.

[0019] 4. By setting up the dredging component, it can change the position distribution of the raw materials at the blocked part at the bottom of the feeding cylinder, causing a gap movement of the raw materials at the blocked part and promoting the fluidity of the raw materials at the bottom of the feeding cylinder. By continuous dredging, the possibility of blockage at the bottom of the feeding cylinder can be reduced.

[0020] 5. Due to the shapes of the horizontal column and the inclined column set, when descending, the arc surface at the bottom can better push aside the raw materials, reducing the obstruction by the raw materials, enabling the horizontal column and the dredging component to better penetrate the blocked raw materials. When the horizontal column and the inclined column rise, the flat surface at the top of the horizontal column and the inclined column can support the raw materials above to rise, reducing the gravitational extrusion of the raw materials inside the feeding cylinder on the blocked part at the bottom of the feeding cylinder and increasing the possibility of discharging the blocked raw materials at the bottom of the feeding cylinder.

Specific implementation mode

[0030] The following will be combined with the drawings and embodiments to detail the implementation mode of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the implementation process of technical effects and implement accordingly.

[0031] Embodiment 1

[0032] In order to be able to guide the position of the raw materials discharged by the loading equipment, prevent the raw materials from spreading around when discharged from the loading equipment, and at the same time serve the purpose of controlling the opening and closing of the discharge port of the loading equipment, Figures 1 - 5 For an embodiment of the present invention, a loading device for abrasive filament production is proposed, which includes a loading cylinder 1 with a blanking port opened at the bottom. The bottom of the loading cylinder 1 is fixedly connected with a frame 2. A blanking guiding component 3 is installed at the bottom of the loading cylinder 1. A hydraulic cylinder 4 for driving the blanking guiding component 3 to lift is installed at the top of the loading cylinder 1. The blanking guiding component 3 includes a hemispherical shell 31. A plurality of sector plates 32 are rotatably connected to the top of the hemispherical shell 31. A discharge port is opened at one end of the sector plate 32 close to the hemispherical shell 31. A guiding port is opened at one end of the outer side of the hemispherical shell 31 far from the sector plate 32. A material blocking component 33 is installed at the top of the sector plate 32. A supporting component 34 for supporting the hemispherical shell 31 and the sector plate 32 is installed at the bottom of the hemispherical shell 31. The diameter of the hemispherical shell 31 is the same as the inner diameter of the blanking port of the loading cylinder 1. During use, the hydraulic cylinder 4 pushes the hemispherical shell 31 to move below the loading cylinder 1, and the supporting component 34 pushes the sector plate 32 to rotate upward. The raw materials of the abrasive filament are poured into the interior of the loading cylinder 1 from above the loading cylinder 1. The raw materials are discharged from the blanking port at the bottom of the loading cylinder 1. The moving process of the raw materials after being discharged from the bottom of the loading cylinder 1 is as follows:

[0033] Part of the raw materials fall onto the sector plate 32, and the raw materials spreading around the feeding port also fall onto the sector plate 32. Then they slide along the sector plate 32 towards the top of the hemispherical shell 31. During this process, part of the raw materials on the sector plate 32 pass through the discharging port, then move along the hemispherical shell 31 to the guiding port on the hemispherical shell 31, and finally fall through the guiding port to a position close to the axis below the hemispherical shell 31. Other raw materials on the sector plate 32 slide to the top of the hemispherical shell 31. Other parts of the raw materials falling from the feeding cylinder 1 directly fall to the top of the hemispherical shell 31. The raw materials at the top of the hemispherical shell 31 slide downwards through the gaps between the sector plates 32 until they fall off the hemispherical shell 31 and land at a position slightly farther from the axis below the hemispherical shell 31.

[0034] When it is necessary to close the feeding cylinder 1 to stop feeding, the hydraulic cylinder 4 drives the hemispherical shell 31 to rise. After the sector plate 32 approaches the feeding cylinder 1, it is pushed by the reaction force and gradually approaches the hemispherical shell 31 until it finally clings tightly to the hemispherical shell 31. The hemispherical shell 31 completely enters the feeding port of the feeding cylinder 1. One end of the bottom of the sector plate 32 presses tightly against the inner wall of the feeding port of the feeding cylinder 1. The hemispherical shell 31 and the sector plate 32 completely block the feeding port of the feeding cylinder 1, causing the feeding cylinder 1 to stop feeding. When feeding is required, the control hydraulic cylinder 4 can drive the hemispherical shell 31 to move below the feeding cylinder 1. It can well limit the raw materials discharged by the feeding equipment, prevent the raw materials from spreading around after being discharged from the feeding port, prevent the workload increase caused by raw material recovery and equipment surface cleaning due to raw material spillage, and at the same time, the feeding port can be directly closed to stop feeding without the need to additionally equip a valve.

[0035] Since part of the raw materials in the feeding cylinder 1 slide to the top of the hemispherical shell 31 after falling onto the sector plate 32, and then slide to the outer circle of the hemispherical shell 31 through the gap between the two sector plates 32, and the other part passes through the discharging port and the guiding port on the hemispherical shell 31 and then falls below the hemispherical shell 31. When the sector plate 32 clings tightly to the hemispherical shell 31, the sector plate 32 can completely cover the guiding port on the hemispherical shell 31. The feeding guiding assembly 3 can not only block the feeding cylinder 1 to stop feeding, but also reduce the blockage of the raw materials and disperse the moving path of the raw materials when the feeding cylinder 1 is feeding without blocking the feeding port, reducing the influence of the valve structure of the feeding cylinder 1 on the discharging.

[0036] In order to enable the hemispherical shell 31 to both block the feeding cylinder 1 and reduce the obstruction to discharging when not blocking the feeding cylinder 1, refer to Figure 4, the support component 34 is used to make the sector plate 32 in a state where its angle can be swing - adjusted. The support component 34 includes an intermediate rod 341 fixedly connected to the bottom of the hemispherical shell 31. An elastic plate 342 is arranged between the intermediate rod 341 and the sector plate 32, and the elastic plate 342 movably penetrates through the guiding opening. A plurality of reinforcing rods 343 are fixedly connected between the intermediate rod 341 and the bottom of the hemispherical shell 31. During use, the elastic plate 342 pushes the sector plate 32 to lift upwards. The reinforcing rods 343 increase the supporting force on the hemispherical shell 31 to prevent the hemispherical shell 31 from deforming after being extruded by too much raw material. When the hemispherical shell 31 rises to block the bottom of the feeding cylinder 1, the sector plate 32 gradually contacts the feeding cylinder 1, and after receiving a reaction force, it gradually approaches the hemispherical shell 31. In this process, the elastic plate 342 is squeezed and bent until the hemispherical shell 31 drops back below the feeding cylinder 1 and no longer contacts the feeding cylinder 1. Then the elastic plate 342 pushes the sector plate 32 to lift upwards again, keeping the sector plate 32 in a state where its angle can be swing - adjusted.

[0037] To change the properties of the abrasive filaments, different raw materials are added as needed. Sometimes, powdered raw materials are added. To prevent the powdered raw materials from escaping and raising dust during feeding, referring to Figure 4 , the material blocking component 33 includes a short rod 331 and a long rod 332 fixedly connected to the top of the sector plate 32. A baffle 333 is fixedly connected to one end of the top of the sector plate 32 close to the hemispherical shell 31. When the sector plate 32 rotates to the lowest position, the maximum distances between the short rod 331 and the long rod 332 and the axis of the hemispherical shell 31 are L1 and L2 respectively, and the inner diameter of the discharge port at the bottom of the feeding cylinder 1 is D1, satisfying the following relationship: 2L1 ≤ D1, 2L2 ≤ D1. During use, the powdered raw materials are poured into the interior of the feeding cylinder 1 and then discharged from the bottom of the feeding cylinder 1. Most of the raw materials directly fall onto the sector plate 32 and the hemispherical shell 31, and a small part of the raw materials diffuses into the surrounding air. The long rod 332 and the short rod 331 play a role in restricting dust in a dense array, blocking the dust when it rises upwards, reducing the degree of dust raising of the powdered raw materials. The baffle 333 makes the raw materials on the sector plate 32 stay at the discharge port of the sector plate 32 and fall. The lengths of the long rod 332 and the short rod 331 ensure that they can enter the interior of the feeding cylinder 1 without being stuck. When the hemispherical shell 31 rises to block the feeding cylinder 1, the long rod 332, the short rod 331, and the baffle 333 can also extrude the raw materials inside the feeding cylinder 1, cutting the filamentous raw materials, improving the adaptability to powdered raw materials and filamentous raw materials, being able to reduce the possibility of powdered raw materials raising dust, and also being able to extrude the filamentous raw materials to reduce their length, facilitating better mixing of the raw materials.

[0038] To install the hydraulic cylinder 4, referring to Figure 1 , a cross - plate 9 is fixedly connected to the top of the feeding cylinder 1. The hydraulic cylinder 4 is installed on the top of the cross - plate 9, and the output end of the hydraulic cylinder 4 movably penetrates through the cross - plate 9. During use, the hydraulic cylinder 4 is fixed on the cross - plate 9.

[0039] Embodiment Two

[0040] To prevent the raw materials from being blocked at the bottom of the feeding cylinder 1, referring to Figures 1 - 7 , on the basis of the first embodiment, a cross column 5 is fixedly connected to the output end of the hydraulic cylinder 4. A round rod 6 is fixedly connected between the cross column 5 and the blanking guiding assembly 3. A dredging assembly 7 is installed at the bottom of the cross column 5. The dredging assembly 7 includes a plurality of square blocks 71 installed at the bottom of the cross column 5. A quadrangular pyramid 72 is fixedly connected to the bottom of the square block 71. A plurality of inclined columns 73 are fixedly connected to the outside of the quadrangular pyramid 72. Both the inclined column 73 and the cross column 5 are semi-cylinders. The tops of the inclined column 73 and the cross column 5 are both flat surfaces. The square block 71 extends into the cross column 5 movably. A limiting column 8 that penetrates the cross column 5 movably is provided at the top of the square block 71. During use, the square block 71 is inserted into the cross column 5, and the limiting column 8 penetrates the cross column 5 and then leaks above the cross column 5. Control the hydraulic cylinder 4 to reciprocate telescopically. The hydraulic cylinder 4 drives the cross column 5 and the dredging assembly 7 to reciprocate up and down. When the dredging assembly 7 descends, the cross column 5 and the quadrangular pyramid 72 push the raw materials downward until the quadrangular pyramid 72 penetrates the raw materials in the feeding cylinder 1 and leaks out from the bottom of the feeding cylinder 1, destroying the structure of the raw materials at the blocked part at the bottom of the feeding cylinder 1, which helps to dredge the blocked raw materials at the bottom of the feeding cylinder 1. Then the hydraulic cylinder 4 drives the cross column 5 and the quadrangular pyramid 72 to rise. The position where the quadrangular pyramid 72 originally was is vacant, and the surrounding raw materials collapse towards the vacant position and then are discharged from the bottom of the feeding cylinder 1. It can change the position distribution of the raw materials at the blocked part at the bottom of the feeding cylinder 1, cause a gap movement of the raw materials at the blocked part, promote the fluidity of the raw materials at the bottom of the feeding cylinder 1, and use continuous dredging to reduce the possibility of blockage at the bottom of the feeding cylinder 1.

[0041] Since both the cross column 5 and the inclined column 73 are semi-cylinders with flat tops, the arc surface at the bottom can better push away the raw materials when descending, reducing the resistance from the raw materials and enabling the cross column 5 and the dredging assembly 7 to better penetrate the blocked raw materials. When the cross column 5 and the inclined column 73 rise, the flat surfaces at the tops of the cross column 5 and the inclined column 73 can support the raw materials above to rise, reducing the gravity extrusion of the raw materials inside the feeding cylinder 1 on the blocked part at the bottom of the feeding cylinder 1 and increasing the possibility of discharging the blocked raw materials at the bottom of the feeding cylinder 1.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
