[0002] During the three-roller mill grinding process, it is necessary to continuously add the fluid material to be processed to the equipment. The traditional way of loading is for workers to lift the barrel and then dump it, which requires the cooperation of multiple people. In addition, the barrel is heavy, the labor intensity is high, the operation is difficult, and manual operation cannot guarantee continuous feeding.

[0003] In the prior art, there have been devices that use conveyor belts to automatically feed the three-roller machine. This device is open to a large extent and is prone to secondary pollution. There have also been devices that use pipelines to automatically feed, but this structure is complex, the material to be ground is relatively viscous, and it is easy to adhere to the conveying pipeline and cause waste. In addition, when changing the grinding material, the pipeline must be flushed, which is complicated and difficult to operate, and is prone to secondary pollution. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a feeding device for a three-roller grinding machine, which realizes automatic feeding and is convenient for feeding without manual lifting and lowering.

[0005] The automatic feeding device of a three-roller machine includes a lifting mechanism, a driving mechanism and a position adjustment mechanism; the lifting mechanism includes a rotating arm, a clamping arm and a barrel; the rotating arm rotates under the drive of the driving mechanism; the rotating arm is rotatably connected to the clamping arm, and the clamping arm is rotatably connected to the barrel.

[0006] The position adjustment mechanism comprises a slider, a guide rail and a position adjustment driving assembly; the slider is slidably connected to the guide rail and reciprocates along the guide rail under the drive of the position adjustment driving assembly.

[0007] The lifting mechanism has a barrel loading and unloading position for loading and unloading the barrel and a material dumping position for dumping the material; when the lifting mechanism is located at the barrel loading and unloading position, the distance between the clamping arm and the ground is smaller than the distance between the clamping arm and the ground when the lifting mechanism is located at the material dumping position; the position adjustment mechanism has a loading and unloading matching position corresponding to the barrel loading and unloading position; when the position adjustment mechanism is located at the loading and unloading matching position, the lifting mechanism can be rotated to the barrel loading and unloading position to facilitate the loading and unloading of the barrel.

[0008] Furthermore, it also includes a frame, and the guide rails are fixedly installed on both sides of the frame.

[0009] Furthermore, the position adjustment drive assembly includes a screw rod rotatably connected to the frame, a sleeve is threadedly connected to the screw rod, the sleeve is fixedly connected to one of the sliders, and one end of the screw rod is connected to a handwheel or a first motor.

[0010] Furthermore, a rotating shaft is fixedly connected to each side of the opening end of the barrel, and the rotating shaft is detachably connected to an end of the clamping arm away from the rotating arm; the clamping arm and the barrel are provided with mutually cooperating limit blocks; the detachable connection is a quick-release connection.

[0011] Furthermore, the driving mechanism includes a servo motor, a speed reduction mechanism and a driving shaft, and a rotating arm is provided at each end of the driving shaft. The servo motor is connected to the driving shaft through the speed reduction mechanism.

[0012] Furthermore, the distance between the rotating arms is adjustable.

[0013] Furthermore, a retractable support rod is fixedly connected between the rotating arms.

[0014] The beneficial effects of the utility model are as follows:

[0015] Firstly, by adjusting the lifting mechanism to the barrel loading and unloading position, the workers can load and unload the barrel on the ground, which reduces the labor intensity of the workers and improves the efficiency of barrel loading and unloading.

[0016] Secondly, the distance between the clamping arms is set to be adjustable, so that when facing barrels of different specifications and models, the loading and unloading of the barrels and the dumping of materials can still be achieved.

[0017] Finally, since the three-roller mill has high requirements for the feeding position during grinding, the feeding position cannot be accurately aligned only through the setting of the lifting mechanism. Then, the outlet position of the barrel is adjusted through the position adjustment mechanism to achieve precise adjustment of the feeding port. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] A three-roller automatic feeding device comprises a lifting mechanism 1, a driving mechanism 4 and a position adjustment mechanism 2; the lifting mechanism 1 comprises a rotating arm 11, a clamping arm 12 and a barrel 13; the rotating arm 11 rotates under the drive of the driving mechanism 4; the rotating arm 11 is rotatably connected to the clamping arm 12, and the clamping arm 12 is rotatably connected to the barrel 13.

[0023] The position adjustment mechanism 2 includes a slider, a guide rail 21 and a position adjustment driving assembly; the slider is slidably connected to the guide rail 21 and reciprocates along the guide rail 21 under the drive of the position adjustment driving assembly.

[0024] The lifting mechanism 1 has a barrel loading and unloading position for loading and unloading the barrel 13 and a material dumping position for dumping materials; when the lifting mechanism 1 is located at the barrel loading and unloading position, the distance between the clamping arm 12 and the ground is smaller than the distance between the clamping arm 12 and the ground when the lifting mechanism 1 is located at the material dumping position; the position adjustment mechanism 2 has a loading and unloading matching position corresponding to the barrel loading and unloading position; when the position adjustment mechanism 2 is located at the loading and unloading matching position, the lifting mechanism 1 can be rotated to the barrel loading and unloading position to facilitate the loading and unloading of the barrel 13.

[0025] Furthermore, a frame is included, and the guide rails 21 are fixedly installed on both sides of the frame.

[0026] Furthermore, the position adjustment drive assembly includes a screw rod 22 rotatably connected to the frame, a sleeve is threadedly connected to the screw rod 22, the sleeve is fixedly connected to one of the sliders, and one end of the screw rod 22 is connected to a handwheel 23 or a first motor.

[0027] Furthermore, a rotating shaft is fixedly connected to each side of the opening end of the barrel 13, and the rotating shaft is detachably connected to one end of the clamping arm 12 away from the rotating arm 11; the clamping arm 12 and the barrel 13 are provided with mutually cooperating limit blocks; the detachable connection is a quick-release connection.

[0028] Furthermore, the driving mechanism 4 includes a servo motor 41 , a speed reduction mechanism 42 and a driving shaft 43 . The two ends of the driving shaft 43 are each provided with a rotating arm 11 . The servo motor 41 is connected to the driving shaft 43 via the speed reduction mechanism 42 .

[0029] Furthermore, the distance between the rotating arms 11 is adjustable; the driving shaft 43 and the rotating arms 11 are slidably connected via a spline; when the position of the rotating arms 11 needs to be limited, a bolt locking mechanism commonly used in the prior art is used for locking and limiting.

[0030] Furthermore, a retractable support rod 5 is fixedly connected between the rotating arms 11 .

[0031] The working process of the three-roller automatic feeding device is as follows:

[0032] The lifting mechanism 1 rotates to the barrel loading and unloading position, and the staff connects the rotating shafts on both sides of the barrel 13 filled with materials to the clamping arm 12 firmly. Then, the servo motor 41 drives the rotating arm 11 to rotate, and the clamping arm 12 lifts the barrel 13 to the material dumping position as the rotating arm 11 rotates. Since there is material in the barrel 13, the bottom of the barrel 13 rotates downward under the action of gravity and abuts against the support rod 5. According to the positional relationship between the outlet of the barrel 13 and the squeezing roller of the three-roller machine, the hand wheel 23 is rotated to adjust the position of the outlet of the barrel 13 so that it is aligned with the squeezing roller position of the three-roller machine. The rotating arm 11 is continuously rotated to dump the materials until all the materials are poured out. In order to prevent the barrel 13 from overturning, mutually cooperating limit blocks are set between the clamping arm 12 and the barrel 13, and the rotation position of the barrel 13 is limited by the mutually cooperating limit blocks. When the material is dumped, the lifting mechanism 1 is rotated in the reverse direction to the barrel loading and unloading position to facilitate loading, unloading and replacement of the barrel 13 .
