[0012] As a preferred embodiment, rollers are rotatably connected between the two main frames and the two auxiliary frames.

[0013] The technical effect of adopting the above further solution is that the can body workpiece is processed between the rollers.

[0025] The technical effect of adopting the above further solution is: by arranging the reinforcing rod between the two main adjustment blocks and between the two auxiliary adjustment blocks, it is made more firm and usable.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are:

[0027] The screw is rotated by shaking the rocker. When the screw rotates, the synchronous pulley on the screw drives the other screw to rotate synchronously through the synchronous belt. Under the action of the thread, the auxiliary adjustment block drives the auxiliary frame to move to adjust the distance between the two rollers. As a result, the present application can adjust the distance between the two rollers, thereby adapting to the processing of cans of different sizes, solving the limitations and complexities caused by the distance problem between the rollers.

[0028] By controlling the synchronous operation of two brushless motors, the two rollers have independent power, the overall operating power is more sufficient, the machine's load capacity is improved, and it can adapt to different usage scenarios.

The brushless motor is supported by a cooling fan, and the motor always runs at a suitable temperature to ensure the overall stable operation of the machine and increase the single operation time of the machine. The use of two brushless motors running synchronously not only makes the two rollers have independent power, ensuring that the machine has more sufficient operating power, but also does not interfere with each other.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] like Figure 1-Figure 5 As shown, this embodiment provides a technical solution: a portable dual-brushless motor driven adjustable spacing roller machine, comprising: a main frame 1, a sub-frame 2 and a spacing adjustment mechanism 5, the main frame 1 and the sub-frame 2 are composed of two frames and a bottom plate, a roller 3, and the roller 3 is rotatably connected between the two frames. The canned product is processed between the rollers 3;

[0042] The spacing adjustment mechanism 5 includes a main adjustment block 51 and a sub-adjustment block 52, which are respectively fixed on both sides of the inner bottom of the main frame 1 and the sub-frame 2, and a screw rod 53 is rotatably connected between the main adjustment block 51 and the sub-adjustment block 52, and the screw rod 53 is threadedly connected to the sub-adjustment block 52, and a synchronous belt assembly is provided on the screw rods 53 of the main adjustment block 51 and the sub-adjustment block 52, and the synchronous belt assembly includes a synchronous pulley 56, which is placed on the screw rods 53 of the two main adjustment blocks 51 and the sub-adjustment block 52, and the two synchronous pulleys 56 are connected by synchronous belt transmission, and one end of one of the screw rods 53 on the main adjustment block 51 and the sub-adjustment block 52 is fixed with a rocker 54;

[0043] The screw rod 53 is rotated by shaking the rocker 54. When the screw rod 53 rotates, the synchronous pulley 56 on the screw rod 53 drives the other screw rod 53 to rotate synchronously through the synchronous belt, and the auxiliary adjustment block 52 drives the auxiliary frame 2 to move under the action of the thread to adjust the distance between the two rollers 3. Therefore, the present application can adjust the distance between the two rollers 3, so as to adapt to the processing of tanks of different sizes, and solve the limitations and complexities caused by the distance problem between the rollers.

[0044] The above solution also has the problem that the main adjustment block 51 and the auxiliary adjustment block 52 may be offset during movement, which may cause the clamping column to be unable to move. Figure 1 As shown: In this solution, a guide column 55 is provided between the main adjustment block 51 and the auxiliary adjustment block 52, and the guide column 55 is slidably connected to the auxiliary adjustment block 52. By directly adding the upper guide column 55 to the main adjustment block 51 and the auxiliary adjustment block 52, the auxiliary adjustment block 52 can be oriented when moving, preventing the positions of the main adjustment block 51 and the auxiliary adjustment block 52 from being offset and causing jamming.

[0045] A step further, such as Figure 2-Figure 5 As shown: the two main adjustment blocks 51 and the two auxiliary adjustment blocks 52 are also rotatably connected with a driving rod 6, a brushless motor 4 is provided on one side of the main frame 1 and the auxiliary frame 2, the driving end of the brushless motor 4 is connected to the driving rod 6, the end of the driving rod 6 away from the brushless motor 4 is provided with a main driving shaft 61, and one end of the roller 3 is provided with a secondary driving shaft 62. The main driving shaft 61 and the secondary driving shaft 62 are connected by a transmission member. A potentiometer 41 is provided on one side of the main frame 1 and the auxiliary frame 2 and above the brushless motor 4. The potentiometer 41 is electrically connected to the brushless motor 4. Then, the speed of the brushless motor 4 is adjusted by the potentiometer 41. By respectively arranging the brushless motor 4 on the main frame 1 and the auxiliary frame 2, the driving rod 6 can drive the roller 3 to rotate under the action of the main driving shaft 61, the auxiliary driving shaft 62 and the transmission parts. The overall self-supporting force of the utility model is evenly distributed throughout the whole body through the split design, which is convenient for maintenance, saves space, and increases the service life of machine parts. The load operation capacity is improved through the main driving shaft 61, the auxiliary driving shaft 62 and the transmission parts. The structure is compact and convenient, safe and reliable to use, and is conducive to the later maintenance of the whole machine.

[0046] By controlling the driving mode of synchronous operation of the two brushless motors 4, the two rollers 3 have independent power, the overall operating power is more sufficient, the load capacity of the machine is improved, and it can adapt to different usage scenarios. The two brushless motors 4 do not interfere with each other and operate independently. Even if one loses power, the machine can still operate. The brushless motor 4 is supported by a cooling fan, and the motor always runs at a suitable temperature to ensure the overall stable operation of the machine and increase the single operation time of the machine. The use of the driving mode of synchronous operation of the two brushless motors 4 not only makes the two rollers 3 have independent power, ensuring that the machine operation power is more sufficient and does not interfere with each other.

[0047] A step further, such as Figure 1 As shown: a reinforcing rod 7 is further provided between the two main adjusting blocks 51 and the two auxiliary adjusting blocks 52. The reinforcing rod 7 is provided between the two main adjusting blocks 51 and the two auxiliary adjusting blocks 52, so that the structure is more firm and usable.

[0048] Working principle:

[0049] like Figure 1-5 As shown:

[0050] When using:

[0051] The screw rod 53 is rotated by shaking the rocker 54. When the screw rod 53 rotates, the synchronous pulley 56 on the screw rod 53 drives the other screw rod 53 to rotate synchronously through the synchronous belt. Under the action of the thread, the auxiliary adjustment block 52 drives the auxiliary frame 2 to move, thereby adjusting the distance between the two rollers 3.

[0052] By controlling the rotation of the two brushless motors 4, the brushless motors 4 drive the roller 3 to rotate through the driving rod 6, the main driving shaft 61 (pulley), the secondary driving shaft 62 (pulley) and the transmission member (belt), thereby processing the can body processing material.

[0053] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
