[0032] like Figure 1 As shown, the automatic refill feeding device 100 for colored pencils provided by the utility model comprises a mounting assembly 1 on which a barrel 2 is detachably mounted, a lifting assembly 4 capable of lifting the mounting assembly 1, and a feeding assembly 3 for pushing the refill material from the barrel 2 to the refill press. The barrel 2 contains the refill material, which is a package for the production and transportation of the refill material. The lifting assembly 4 and the barrel 2 can adopt the existing structure in the prior art, which will not be described in detail here. Figure 7 , the funnel-shaped discharge mask of the mounting component 1 is arranged on the opening of the barrel 2, and a cloth cover 11 is fixed on the discharge port of the mounting component 1 by a tying rope. In the process of moving the barrel 2 to the top of the feeding component 3, the cloth cover 11 blocks the discharge port of the mounting component 1. The lifting component 4 lifts the barrel 2 through the mounting component 1, wherein the opening of the barrel 2 faces downward, and then the lifting component 4 moves the barrel 2 to the top of the feeding component 3, opens the cloth cover 11 that blocks the discharge port of the mounting component 1, and the cloth cover 11 extends into the feeding component 3, and the refill material in the barrel 2 passes through the discharge port of the mounting component 1 and the cloth cover 11 into the feeding component 3. The setting of the cloth cover 11 can not only facilitate the operator to block the discharge port of the mounting component 1, but also make it unnecessary to adjust the distance between the barrel 2 and the feeding component 3 again when the barrel 2 is moved to the top of the feeding component 3.
[0033] Also refer to Figures 2 to 6The feeding assembly 3 includes a support seat 39, a sleeve 32 movably mounted on the support seat 39, a pusher 34 movably mounted in the sleeve 32, and a hopper 31 mounted on the sleeve 32. Preferably, a guide groove 391 is provided on the upper side of the support seat 39, and the sleeve 32 is movably mounted in the guide groove 391 through a moving assembly. Also preferably, the guide groove 391 is a dovetail groove. Further, two guide grooves 391 parallel to each other are provided on the upper side of the support seat 39, and the guide grooves 391 are arranged along the moving direction of the sleeve 32. The moving assembly includes a first cylinder 38 mounted on the lower side of the support seat 39, a connecting block 37 mounted on the output shaft of the first cylinder 38, a slider 36 movably engaged in the guide groove 391, and a leg 35 mounted on the slider 36, and the sleeve 32 is mounted on the leg 35. Preferably, the legs 35 are fixed to the slider 36 by welding, and the sleeve 32 is fixed to the legs 35 by welding. The first cylinder 38 can adopt the existing structure in the prior art, which will not be described in detail here. The connecting block 37 is roughly T-shaped. The upper end of the T-shaped connecting block 37 is connected between the two legs 35, for example, fixed to the two legs 35 by welding. The support seat 39 is provided with a through hole 392 at the position corresponding to the connecting block 37. The through hole 392 is roughly rectangular. The through hole 392 is extended along the moving direction of the sleeve 32. The lower end of the T-shaped connecting block 37 extends from the through hole 392 and is connected to the output shaft of the first cylinder 38. When the first cylinder 38 is working, the output shaft of the first cylinder 38 can push the T-shaped connecting block 37 to move back and forth along the through hole 392, thereby driving the sleeve 32 to move back and forth, so that the sleeve 32 is close to or away from the lead raw material inlet of the pressing machine.
[0034] The sleeve 32 is roughly a hollow cylinder with one end open. A slot 321 is provided on the lower side of the sleeve 32, and the slot 321 is arranged along the axial direction of the sleeve 32, and the slot 321 penetrates the wall of the sleeve 32 in the radial direction of the sleeve 32. Preferably, the slot 321 extends from the closed end of the sleeve 32 to the middle position of the sleeve 32. The pusher 34 is engaged on the inner side of the sleeve 32. The pusher 34 includes a pusher body 341 and a protrusion 342. The pusher body 341 is roughly cylindrical. In the axial direction of the sleeve 32, the length of the pusher body 341 is greater than the length of the slot 321. The protrusion 342 is arranged on the side wall of the pusher body 341 along the radial direction of the pusher body 341, and extends from the slot 321 of the sleeve 32. Preferably, the protrusion 342 is arranged on one end of the side wall of the pusher body 341 adjacent to the closed end of the sleeve 32. The second cylinder 33 is connected to the protrusion 342. The second cylinder 33 is installed on the lower side of the sleeve 32, between the legs 35. When the axial end of the pusher 34 adjacent to the protrusion 342 fits on the closed end of the sleeve 32, the feed port of the hopper 31 is completely connected with the sleeve 32, and as the pusher 34 moves toward the open end of the sleeve 32, the feed port of the hopper 31 is gradually blocked so as to completely block the feed port of the hopper 31. When the pusher 34 is adjacent to the open end of the sleeve 32, the lead material falling into the sleeve 32 is pushed out to the lead material inlet of the pressing machine, and at this time, the pusher 34 completely blocks the feed port of the hopper 31.
[0035] The upper side of the hopper 31 is provided with a baffle 311 extending upwardly. When the sleeve 32 moves relative to the support seat 39, the baffle 311 drives the barrel 2 to move, causing the refill material in the barrel to shake, preventing the refill material from being discharged unevenly and preventing the barrel from escaping from the hopper.
[0036] Figure 8 The schematic diagram of the colored pencil lead manufacturing device 200 of the utility model is shown. The lead manufacturing device 200 includes a pressing machine and the above-mentioned lead automatic feeding device 100. The pressing machine can adopt the existing structure in the prior art, which will not be described in detail here. The lead automatic feeding device 100 can automatically push the lead raw material into the lead raw material inlet of the pressing machine to manufacture colored lead.
[0037] When in use, the lifting assembly 4 moves the material barrel 2 to the top of the feeding assembly 3, opens the cloth cover 11 that blocks the discharge port of the mounting assembly 1, and the cloth cover 11 extends into the feeding assembly 3. The refill material in the material barrel 2 passes through the discharge port of the mounting assembly 1 and the cloth cover 11 and enters the sleeve 32 of the feeding assembly 3. The first cylinder 38 drives the sleeve 32 to move toward the refill material inlet of the pressing machine through the moving assembly. When the open end of the sleeve 32 moves to the top of the refill material inlet of the pressing machine, the second cylinder 33 drives the pushing piece 34 to move and pushes the refill material that falls into the sleeve 32 into the refill material inlet of the pressing machine; then the first cylinder 38 drives the sleeve 32 away from the refill material inlet of the pressing machine to prevent it from obstructing the pressing work of the pressing machine, and the second cylinder 33 drives the pushing piece 34 to return to its position for the next pushing work.
[0038] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
