[0051] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0052] like Figure 1-Figure 4 A cup bottom loading device is shown, comprising:

[0053] Workbench 1;

[0054] A material tray 4 is installed on the workbench 1 and is provided with a material loading hole 41;

[0055] A material rack 5 is arranged on the material tray 4 and is located at the top material hole 41. A material bin for storing materials is arranged in the material rack 5;

[0056] The material grabbing mechanism 3 is movably arranged above the workbench 1 and is used to grab the material in the silo and transport it to a set position;

[0057] The lifting mechanism 2 is arranged below the workbench 1 and is used for lifting the materials in the silo.

[0058] The ejecting mechanism 2 includes: a lifting assembly and an ejector rod 21. The lifting assembly is installed below the material tray 4. The ejector rod 21 is connected to the lifting assembly, and the lifting assembly is used to control the lifting and lowering of the ejector rod 21 in the material bin.

[0059] The upper end of the push rod 21 can pass through the material ejection hole 41, so that the push rod 21 can be inserted into the silo. When the push rod 21 is inserted into the silo, its upper end can be against the material at the bottom of the silo. When the push rod is gradually lifted, the material in the silo will also be lifted, thereby realizing the lifting of the material in the silo.

[0060] A plurality of material racks 5 are arranged on the material tray 4. When the material on one of the material racks 5 is completely used up, the material tray 4 can rotate to move another material rack 5 filled with material to the top of the material lifting mechanism 2. The material rack 5 moved away by the material tray 4 can be used to replenish the material when the material stored in other material racks 5 is used, thereby improving the working efficiency.

[0061] A divider 44 is provided below the material tray 4, so that the turntable can rotate after a fixed period of time, thereby moving another material rack 5 to the top of the lifting mechanism 2, and the materials stored in each material rack 5 can be evenly delivered.

[0062] It should be noted that the material placed in the silo cannot fall through the top hole 41 .

[0063] like Figure 1-Figure 4 As shown, the lifting assembly includes:

[0064] The slide seat 22 is vertically arranged on the fixing frame 6 through the slide rail 63, and the push rod 21 is fixed on the slide seat 22 through at least one fixing seat 221. In this embodiment, two fixing seats 221 are arranged on the slide seat 22 to fix the push rod 21;

[0065] The screw rod 24 has both ends fixed to the fixed frame 6 through a rotating seat 64;

[0066] The transmission sleeve 25 is threadedly sleeved on the screw rod 24 and connected to the slide seat 22 through the connecting piece 26;

[0067] The driving motor 23 is mounted on the fixing frame 6 , and the output end thereof is connected to the screw rod 24 .

[0068] When the driving motor 23 rotates, the screw rod 24 is driven to rotate, and the transmission sleeve 25 sleeved on the outside of the screw rod 24 is connected to the connecting member 26, and the connecting member 26 is connected to the slide seat 22, so the transmission sleeve 25 does not rotate synchronously with the screw rod 24. When the screw rod 24 rotates, the transmission sleeve 25 moves up and down along the screw rod 24, and then drives the slide seat 22 to move through the connecting member 26, so as to achieve the purpose of lifting and lowering the push rod 21.

[0069] like Figure 1-Figure 6As shown, it also includes a fixing frame 6, and the ejecting mechanism 2 is installed on the fixing frame 6. The upper end of the fixing frame 6 has a connecting seat 61, and a plurality of special-shaped adjustment holes 62 are formed on the connecting seat 61. A screw hole 11 is opened on the surface of the workbench 1. Through the cooperation of the special-shaped adjustment hole 62, the screw hole 11 and the bolt, the fixing frame 6 can be translated on the workbench 1, so as to adjust the fixed position of the ejecting mechanism 2 relative to the workbench 1.

[0070] In this embodiment, the special-shaped adjustment hole 62 is specifically a cross-shaped adjustment hole, and the projection of the special-shaped adjustment hole 62 on the workbench 1 completely covers the outside of the screw hole 11. The screw hole 11 and the special-shaped adjustment hole 62 are limited and fixed by bolts, so that the connecting seat 61 can be fixed on the workbench 1.

[0071] When the bolt is loosened, the special-shaped adjustment hole 62 can be moved in four directions relative to the screw hole 11, front, back, left, and right. As long as the movement does not cause the screw hole 11 to leave the projection range of the special-shaped adjustment hole 62 on the workbench 1, the screw hole 11 and the special-shaped adjustment hole 62 can be normally connected and fixed.

[0072] The ejector mechanism 2 is arranged on the fixed frame 6, and the material tray 4 is arranged on the workbench 1. Therefore, by adjusting the position of the fixed frame 6 on the workbench 1, the relative position between the ejector mechanism 2 and the workbench 1 can be adjusted. And by moving the position of the ejector rod 21, the ejector rod 21 can be accurately located below the ejector hole 41 of the material tray 4. This operation is very convenient, and the adjustment can be made without disassembling the entire ejector mechanism 2 or the material tray 4. When confirming the position, it can be directly observed from above the material tray 4, and adjustments can be made in a timely and rapid manner.

[0073] like Figure 1-Figure 6 As shown, the material rack 5 includes several groups of adjustment blocks 51 and baffles 52. The baffles 52 are connected to the front end of the adjustment blocks 51. Several slide grooves 42 are formed on the material tray 4. The slide grooves 42 are circumferentially distributed around the top material hole 41. The adjustment blocks 51 are movably arranged in the corresponding slide grooves 42, so that a material bin is surrounded by the several baffles 52.

[0074] A plurality of positioning holes 43 are formed in the slide groove 42, and an adjusting hole 53 is formed on the adjusting block 51.

[0075] like Figure 1-Figure 7 As shown, the transmission sleeve 25 is formed with a convex ring portion 251, and the convex ring portion 251 is formed with a plurality of screw holes 252;

[0076] A sleeve hole 261 and a plurality of through holes 262 are formed on the connecting member 26. After the transmission sleeve 25 passes through the sleeve hole 261, the screw hole 252 corresponds to the through hole 262. The connecting member 26 is then connected to the screw hole 252 by passing the end of the screw through the sleeve hole 261, and the connecting member 26 is fixed on the convex ring portion 251, so that the connecting member 26 can maintain the same motion state as the transmission sleeve 25.

[0077] Furthermore, the radius of the sleeve hole 261 matches the outer diameter of the transmission sleeve 25, so that the connecting member 26 can be sleeved on the outside of the transmission sleeve 25, thereby preventing the connecting member 26 from shaking. At the same time, the cooperation between the sleeve hole 261 and the transmission sleeve 25 also plays a positioning role, so as to facilitate the alignment between the second through hole 262 and the second screw hole 252.

[0078] like Figure 1-Figure 7 As shown, the second through hole 262 is connected to the sleeve hole 261 , and the length direction of the second through hole 262 passes through the center of the sleeve hole 261 .

[0079] Due to errors in the production process, the positions of the second through hole 262 and the second screw hole 252 are not necessarily accurate to the designed positions, and it is inconvenient to simply use the second through hole 262 and the second screw hole 252 with the same aperture to match each other in the actual assembly process. By increasing the area of ​​the second through hole 262, it is convenient for the operator to quickly screw the connecting member 26 onto the belt transmission sleeve 25.

[0080] like Figure 1-Figure 7 As shown, the material grabbing mechanism 3 includes:

[0081] A bracket 31, on which a suction cup is arranged, and the suction cup is used to grab materials from the material rack 5;

[0082] The mechanical arm 32 has a lifting and lowering connecting rod 33 at its front end, and the bracket 31 is connected to the connecting rod 33 so that the connecting rod 33 can drive the bracket 31 to lift and lower.

[0083] The mechanical arm 32 includes a base 321, a swing arm 322 and a forearm 323, wherein the connecting rod 33 is arranged on the forearm 323. The forearm 323 is connected to the base 321 through the swing arm 322, so that the forearm 323 can be driven to move.

[0084] After the suction cup on the bracket 31 absorbs the material, the mechanical arm 32 will drive the bracket 31 to move and transport the material to other equipment.

[0085] like Figure 1-Figure 7 As shown, a mounting frame 65 is formed on the fixing frame 6 , and the driving motor 23 is arranged on the mounting frame 65 .

[0086] A driving wheel 27 is sleeved on the motor shaft of the driving motor 23, and a driven wheel 28 is sleeved on the bottom end of the screw rod 24. The driving wheel 27 and the driven wheel 28 are connected by a synchronous belt 29, so that the driving motor 23 can drive the screw rod 24 to rotate.

[0087] If the drive motor 23 is directly screwed to the lower end of the screw rod 24, the overall length will be longer, resulting in the need to increase the height of the workbench 1 to prevent the drive motor 23 from colliding with the ground. A higher height of the workbench 1 is also inconvenient when other equipment is used.

[0088] By providing the mounting frame 65 to fix the driving motor 23 , the space below the workbench 1 can be effectively utilized.

[0089] As a preferred embodiment, the connecting member 26 and the sliding seat 22 can be connected into one piece by screwing, welding or integral molding.

[0090] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
