[0028] like Figure 1As shown, a mold cleaning machine includes a frame 3, a rotary adjustment mechanism 1, and an inner cavity cleaning mechanism 2. Both the rotary adjustment mechanism 1 and the inner cavity cleaning mechanism 2 are mounted on the frame 3. The rotary adjustment mechanism 1 includes a first support assembly 11 having at least two rotational support points and a second support assembly 12 having at least two rotational support points. The rotational axes of the at least four rotational support points are arranged on the same horizontal plane along a first direction, for supporting the smooth rotation of a workpiece 100. The inner cavity cleaning mechanism 2 includes a conveying assembly 21 and a cleaning assembly 22. The conveying assembly 21 has translational freedom along the first and second directions. The cleaning assembly 22 is disposed at the end of the conveying assembly 21. The conveying assembly 21 drives the cleaning assembly 22 to remove dust from the inner wall of the workpiece 100 rotating on the rotary adjustment mechanism 1.

[0029] It is worth noting that the first direction in this embodiment is a horizontal direction. Specifically, the first direction is the linear direction of the relative position between the first support assembly 11 and the second support assembly 12. In other embodiments, the first direction can be any direction on the horizontal plane. In this embodiment, the second direction is a vertical direction perpendicular to the first direction.

[0030] like Figure 2 As shown, specifically, the first support assembly 11 includes a first support frame 111, a driving member, and at least two first rotating wheels 113. The first support frame 111 is fixed to the frame 3. The first rotating wheels 113 are rotatably connected to the side of the first support frame 111 facing the second support assembly 12. The first rotating wheels 113 serve as the rotation support points of the first support assembly 11. In this embodiment, there are two first rotating wheels 113, and the rotational axes of the two first rotating wheels 113 are arranged on the same horizontal plane along the first direction to support the outer wall of the workpiece 100. In other embodiments, there may be multiple first rotating wheels 113 distributed in a circular array on the side wall of the first support frame 111.

[0031] Specifically, the first driving member 112 is a driving motor, which is fixed on the frame 3. The two first rotating wheels 113 are connected to the output shaft of the first driving member 112 through belts and gears. The first driving member 112 drives the first rotating wheel 113 to rotate, thereby driving the workpiece 100 supported on the first rotating wheel 113 to rotate.

[0032] The second support assembly 12 includes a second support frame 121 and at least two second rotating wheels 122. The second support frame 121 is slidably connected to the frame 3 along the first direction to adjust the distance between the first support assembly 11 and the second support assembly 12, thereby supporting workpieces 100 of different sizes.

[0033] The second rotating wheel 122 is rotatably connected to the side of the second support frame 121 facing the first support frame 111. The second rotating wheel 122 is the rotation support point of the second support assembly 12. In this embodiment, there are two second rotating wheels 122, and the rotation axes of the two second rotating wheels 122 are arranged on the same horizontal plane along the first direction to support the outer wall of the workpiece 100. In other embodiments, there can be multiple second rotating wheels 122 and they are distributed in a circular array on the side wall of the second support frame 121. The outer wall of one end of the workpiece 100 abuts against the first rotating wheel 113, and the outer wall of the other end abuts against the second rotating wheel 122. When the first driving member 112 drives the first rotating wheel 113 to rotate, the workpiece 100 is driven to rotate smoothly.

[0034] The rotation adjustment mechanism 1 also includes a first limiting wheel 13 and a second limiting wheel 14. The first limiting wheel 13 is rotatably connected to the first support frame 111, and the second limiting wheel 14 is rotatably connected to the second support frame 121. The rotation center axis of the first limiting wheel 13 and the rotation center axis of the second limiting wheel 14 are arranged along the second direction. The outer peripheral side of the first limiting wheel 13 abuts one end face of the workpiece 100, and the second limiting wheel 14 abuts the other end face of the workpiece 100. The first limiting wheel 13 cooperates with the second limiting wheel 14 to limit the workpiece 100 in the first direction, and there is rolling friction between the first limiting wheel 13 and the second limiting wheel 14 and the workpiece 100, thereby reducing the wear of the first limiting wheel 13 and the second limiting wheel 14 on the workpiece 100.

[0035] The frame 3 is further provided with a limiting mechanism 4, which includes a rotating frame 41 and a limiting frame 42. The rotating frame 41 is rotatably connected to the frame 3, and the limiting frame 42 is vertically slidably connected to the rotating frame 41. The limiting frame 42 is rotatably connected to two third rotating wheels 43, and the rotational axes of the two third rotating wheels 43 are arranged in parallel. The rotating frame 41 drives the limiting frame 42 to rotate, so that the limiting frame 42 is located on top of the workpiece 100. The limiting frame 42 slides relative to the rotating frame 41 toward the workpiece 100, so that the two third rotating wheels 43 abut the outer wall of the workpiece 100. The first support assembly 11, the second support assembly 12, and the limiting mechanism 4 cooperate to limit the outer wall of the workpiece 100.

[0036] The conveying assembly 21 includes a first slide 211 and a second slide 212. The first slide 211 is connected to the frame 3 by sliding along a first direction, and the second slide 212 is connected to the first slide 211 by sliding along a second direction. The cleaning assembly 22 is arranged at one end of the second slide 212 away from the first slide 211.

[0037] like Figure 3As shown, the cleaning assembly 22 includes a first take-up roller 221 and a second take-up roller 222. The first take-up roller 221 and the second take-up roller 222 are both rotatably connected to the second carriage 212. The rotational axis of the first take-up roller 221 and the rotational axis of the second take-up roller 222 are both arranged along the first direction. The second take-up roller 222 is driven and controlled by a motor. The first take-up roller 221 is wrapped with a dust-free cloth 223, which then passes around the second take-up roller 222. The motor drives the second take-up roller 222 to rotate, thereby gradually wrapping the dust-free cloth 223 from the first take-up roller 221 to the second take-up roller 222.

[0038] A cleaning roller 5 and a floating mechanism 6 are provided between the first winding roller 221 and the second winding roller 222. The cleaning roller 5 is disposed at the end of the second slide 212 via the floating mechanism 6. The floating mechanism 6 comprises a bracket 61 and a floating frame 62. The bracket 61 is fixedly connected to the end of the second slide 212. The floating frame 62 is fixedly provided with a plurality of slide bars 63. The slide bars 63 are slidably connected to the bracket 61 along the second direction. A stopper is fixedly provided at the top of the slide bar 63. The stopper has a diameter greater than that of the slide bar 63, thereby preventing the slide bar 63 from detaching from the bracket 61. The slide bar 63 is sleeved with a spring 65. One end of the spring 65 is fixedly connected to the bracket 61, and the other end is fixedly connected to the floating frame 62. The cleaning roller 5 is rotatably connected to the floating frame 62. The rotational axis of the cleaning roller 5 is arranged along the first direction. The dust-free cloth 223 passes from the first winding roller 221 around the cleaning roller 5 and is wound around the second winding roller 222.

[0039] The floating frame 62 is provided with an air hole, which is a through hole and is arranged toward the cleaning wheel roller 5. The bracket 61 is slidably connected to the air pipe 64. The air pipe 64 is fixedly connected to the floating frame 62, and the air pipe 64 is connected to the air hole. The other end of the air pipe 64 is connected to the alcohol pressure tank, and the cleaning wheel roller 5 is blown through the air pipe 64 to cool it down.

[0040] Principle of Operation: The workpiece 100 is hoisted onto the first support assembly 11 and the second support assembly 12. Specifically, the first rotating wheel 113 and the second rotating wheel 122 abut against the outer wall of the workpiece 100 to support the workpiece 100. The second support frame 121 slides relative to the frame 3, causing the first limiting wheel 13 and the second limiting wheel 14 to abut against the ends of the workpiece 100, limiting the workpiece 100 in the first direction.

[0041] The rotating frame 41 rotates so that the limiting frame 42 is located on top of the workpiece 100. The limiting frame 42 slides relative to the rotating frame 41 in the second direction until the third rotating wheel 43 abuts the workpiece 100. The first rotating wheel 113, the second rotating wheel 122, and the third rotating wheel 43 cooperate to limit the outer circumference of the workpiece 100. The first driving member 112 drives the first rotating wheel 113 to rotate, thereby driving the workpiece 100 to rotate at a constant speed.

[0042] The first slide 211 moves along the first direction towards the workpiece 100, when the cleaning roller 5 just enters the workpiece 100, the first slide 211 stops, the second slide 212 drives the cleaning roller 5 to move along the second direction towards the inner wall of the workpiece 100, so that the dust-free cloth 223 on the cleaning roller 5 can be attached to the inner wall of the workpiece 100, at this time the spring 65 is in the compressed state, so that the cleaning roller 5 can be tightly contacted with the workpiece 100 while reducing the pressure of the cleaning roller 5 on the workpiece 100, after the first slide 211 and the second slide 212 complete the positioning of the cleaning roller 5, the first driving part 112 drives the first rotating wheel 113 to rotate, the first rotating wheel 113 drives the workpiece 100 to rotate, the first slide 211 moves along the first direction, so as to clean the inner wall of the workpiece 100.
