[0017] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0018] Aiming at the existing problems, the utility model provides a drum ball mill with a novel drum positioning method.

[0019] In one embodiment, a new type of roller positioning method is provided for a roller ball mill that can be mounted on a truss and moved. Figures 1 to 2 As shown, it includes a frame 1, a roller 6, a roller sliding mechanism, a roller rotating mechanism, a roller positioning mechanism and a roller power mechanism. The roller is arranged on the frame through the roller sliding mechanism, the roller is arranged on the roller sliding mechanism through the roller rotating mechanism, the roller positioning mechanism is arranged on the frame, the roller positioning mechanism positions the roller, and the roller power mechanism is connected to the roller to provide power to the roller.

[0020] The drum includes a front flange cover and a drum driven gear 8, and the front flange cover is connected to the drum driven gear 8;

[0021] The drum power mechanism includes a reducer output gear, a reducer 10 and a machine cover 11. The drum passive gear 8 and the reducer output gear 9 are designed to be detachably engaged; the reducer 10 is connected to the reducer output gear 9, and the reducer 10 is arranged in the machine cover 11.

[0022] The roller positioning mechanism includes a proximity switch 13 , an electromagnet 12 and a control panel 14 . The proximity switch 13 and the electromagnet 12 are arranged on the frame. The control panel 14 is connected to the electromagnet 12 and is arranged on the machine cover 11 .

[0023] The roller sliding mechanism includes a linear guide rail 2, a slider 3, and a roller support plate 4, and the electromagnet 12 can be adsorbed on the roller support plate; the linear guide rail 2 is arranged on the frame, the slider 3 is arranged on the linear guide rail, and the roller 6 is arranged on the slider 3 through the roller rotation mechanism.

[0024] Two linear guide rails 2 are mounted on the frame 1 by screws. Two sliders 3 are mounted on each linear guide rail 2. A roller support plate 4 is mounted on the sliders 3 by screws.

[0025] There are two linear guide rails 2. Each linear guide rail 2 is fixedly mounted on the frame 1 by screws, and two sliders 3 are installed on each linear guide rail 2, and the sliders 3 can slide on the linear guide rail 2.

[0026] The roller rotation mechanism includes a rear support roller 5 and a front support roller 7. The rear support roller 5 and the front support roller 7 are both arranged on the roller support plate 4. The rear support roller 5 and the front support roller 7 have bearings therein.

[0027] The drum further comprises a rear flange and a front flange, wherein the rear flange is arranged on the rear supporting roller 5 , and the front flange is arranged on the front supporting roller 7 .

[0028] Two rear support rollers 5 and two front support rollers 7 are screwed onto the roller support plate 4. The roller 6 rests on the two rear support rollers 5 and the two front support rollers 7. The front and rear flanges of the roller 6 fit within the grooves of the two rear support rollers 5 and the two front support rollers 7. The roller driven gear 8 on the roller 6 meshes with the speed reducer output gear 9. This gear meshing causes the speed reducer 10 to rotate, driving the roller 6 to rotate.

[0029] The roller support plate 4 is screwed onto the four sliders 3. Two rear support rollers 5 and two front support rollers 7 are also screwed onto the roller support plate 4. The two rear support rollers 5 and the two front support rollers 7 are symmetrically mounted along the centerline of the roller support plate 4, with the rear support rollers 5 and 7 spaced a distance apart. Bearings are installed within the rear and front support rollers 5 and 7, allowing them to rotate freely about their axis. Grooves are machined into the rear and front support rollers 5 and 7, and the front and rear flanges of the roller 6 fit within these grooves. The four rollers support the roller 6 and restrict its left-right and forward-backward movement. When the roller 6 is pushed or pulled, it drives the roller support plate 4 and sliders 3 to slide on the linear guide 2. Rotating the roller 6 allows it to rotate flexibly about its centerline.

[0030] The drum 6 is provided with front and rear flanges and a cover plate. The cover plate is provided with a shaft on which a drum driven gear 8 is mounted.

[0031] The reducer 10 is mounted on the frame 1. The reducer output gear 9 is mounted on the output shaft of the reducer 10. The reducer output gear 9 is meshed with the drum driven gear 8.

[0032] The cover 11 is mounted on the frame 1. The cover 11 protects the drum driven gear 8, the reducer output gear 9, and the reducer 10 in the cover 11 to avoid the occurrence of safety accidents.

[0033] Electromagnet 12 is screwed to frame 1. When it receives a signal from proximity switch 13, it is energized. The electromagnetic force of electromagnet 12 pulls roller support plate 4 forward, firmly adhering to it. This causes roller driven gear 8 to mesh with reducer output gear 9. Because roller support plate 4 is held in place by the electromagnetic force of electromagnet 12, roller 6 does not move.

[0034] The proximity switch 13 is mounted on the frame 1 and pushes the roller 6 forward. When the baffle on the roller support plate 4 blocks the proximity switch 13, the proximity switch 13 receives a signal and the electromagnet 12 is energized. The electromagnetic force of the electromagnet 12 attracts the roller support plate 4, causing it to move forward. The roller support plate 4 does not stop until it touches the electromagnet 12. At this time, the roller driven gear 8 meshes with the speed reducer output gear 9.

[0035] The control panel 14 is installed on the hood 11. The control panel 14 has electrical components such as a run button, an emergency stop button, and a touch screen to ensure the safe operation of the equipment.

[0036] The operation of the drum ball mill with a new drum positioning method of the utility model:

[0037] Turn on the power supply to supply power to the drum ball mill, and the power indicator light on the control panel will light up.

[0038] The roller 6 is placed on the two rear supporting rollers 5 and the two front supporting rollers 7. When placing the roller 6, the front and rear flanges of the roller 6 and the cover of the front flange need to be placed in the grooves of the rear supporting rollers 5 and the front supporting rollers 7. This will position the roller 6 on the rollers and prevent it from moving left and right or front and back. The rear supporting rollers 5 and the front supporting rollers 7 are equipped with bearings that allow the rollers to rotate around their axis. Therefore, rotating the roller 6 can make it rotate flexibly around its axis on the rollers.

[0039] Roller 6 is pushed forward. Driven by friction, roller 6 pushes roller support plate 4 and slider 3 forward along linear guide 2. After moving a certain distance, the barrier on roller support plate 4 blocks proximity switch 13. This signal is received by proximity switch 13, energizing electromagnet 12. Its electromagnetic force attracts roller support plate 4, causing it to move forward. It stops only when roller support plate 4 abuts against electromagnet 12. At this point, roller driven gear 8 meshes with reducer output gear 9. When the equipment is operating, reducer 10 drives roller 6, and the grinding balls inside roller 6 grind the material. During this grinding process, electromagnet 12 maintains a tight grip on roller support plate 4, securing it in place and preventing roller 6 from moving, instead rotating flexibly around its centerline.

[0040] When the roller driven gear 8 is not aligned with the clearance of the reducer output gear 9, the roller driven gear 8 on roller 6 hits the reducer output gear 9 and is blocked by it. Roller 6 cannot be pushed forward, and the roller driven gear 8 and reducer output gear 9 are not meshing. At this point, roller 6 can be rotated left or right to align the clearance of the reducer output gear 9. When the roller driven gear 8 is aligned with the clearance of the reducer output gear 9, the electromagnetic force of electromagnet 12 forces roller support plate 4 to move forward only until it contacts electromagnet 12, where it stops. At this point, roller driven gear 8 and reducer output gear 9 are fully meshed. Because the roller support plate 4 is firmly held by the electromagnetic force of electromagnet 12, roller 6 remains completely positioned during operation, without moving left or right or forward or backward, and rotates only about the centerline of roller 6's axis.

[0041] After setting the operating parameters on the control panel's touchscreen, click the Start button. The motor will rotate at the set speed and program, driving the reducer output gear 9. Through the meshing of the reducer output gear 9 and the roller driven gear 8, the roller 6 rotates. The front and rear support rollers, acting under friction, rotate about their axis. The grinding balls inside the roller 6 grind the material inside. When the material inside the roller 6 is fully ground, the equipment automatically shuts down. Click the power-off button for electromagnet 12 on the control panel's touchscreen to de-energize the electromagnet 12, eliminating its electromagnetic force. This pulls the roller 6 backward, driving the roller support plate 4 and slider 3 backward along the linear guide 2. The roller driven gear 8 disengages from the reducer output gear 9, and the barrier of the roller support plate 4 clears the proximity switch 13. When the roller 6 is pulled to the unloading position, it is removed, completing the entire operation.

[0042] The drum ball mill with a new drum positioning method of the utility model has the following beneficial effects:

[0043] The electromagnet 12 is used to attract the roller support plate 4, so that the roller support plate 4 is firmly attracted by the electromagnetic force of the electromagnet 12. During the operation of the equipment, the roller 6 is completely in a fixed state and does not move left or right or forward and backward. It only rotates around the axis of the roller 6. The front flange cover design can prevent materials from falling out of the roller 6.

[0044] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
