[0042] like Figures 1 to 2 As shown, an embodiment of the present invention provides a screw barrel cleaning device, which includes a frame 1, a cleaning assembly 2, and a dust collection assembly 3. The frame 1 includes a placement platform 11, and the cleaning assembly 2 is slidably arranged on the placement platform 11 so that the cleaning assembly 2 can move relative to the screw barrel after entering the inner cavity of the screw barrel. The cleaning assembly 2 includes a cleaning member 22 and a connecting pipe 23. The connecting pipe 23 can separate the cleaning member 22 from the placement platform 11, facilitating the cleaning member 22 to extend into the inner cavity of the screw barrel and reducing the positional interference between the placement platform 11 and the screw barrel.

[0043] The dust collection assembly 3 includes a dust collector 31 and a dust collection head 32. The dust collection head 32 is arranged on the connecting pipe 23, and the air paths of the dust collection head 32 and the dust collection head 31 are connected to the inner cavity of the connecting pipe 23. The dust collection head 32 and the cleaning piece 22 are arranged at the same end position of the connecting pipe 23. When the dust collector 31 is started, it can suck air into the dust collection head 32 through the connecting pipe 23, so as to effectively absorb impurities in the cleaning process of the cleaning piece 22.

[0044] With such an arrangement, when in use, the cleaning component 2 can slide under the action of external force, and the cleaning piece 22 enters the inner cavity of the screw barrel. The connecting pipe 23 can drive the cleaning piece 22 to move together so that the cleaning piece 22 cleans the inner cavity of the screw barrel. By applying different external forces to the cleaning component 2, the cleaning piece 22 of the cleaning component 2 can be moved axially in the inner cavity of the screw barrel so as to clean different positions on the screw barrel. When the vacuum cleaner 31 is started, it can suck air into the vacuum head 32 through the connecting tube 23, forming a negative pressure at the vacuum head 32, and the vacuum head 32 and the cleaning member 22 are arranged at the same end position of the connecting tube 23, and the two are close to each other, which can effectively adsorb the impurities at the cleaning position of the cleaning member 22 and the impurities accumulated in the screw barrel and transport them to the vacuum cleaner 31 through the tube cavity of the connecting tube 23 for unified treatment, reducing the adhesion of impurities on the surface of the cleaning member 22 and the bottom of the screw barrel, effectively improving the cleaning effect of the cleaning member 22 on the screw barrel, and making the cleaning operation more efficient, solving the problem of poor cleaning effect of the cleaning member 22 on the screw barrel in the related art.

[0045] In this embodiment, the frame 1 can be a Q235 plate-like structure or a truss structure. Casters can be provided at the bottom of the frame 1, and the casters can be provided with brakes, providing both movement and braking functions. Fixed feet can also be provided at the bottom of the frame 1 to support and secure the frame 1 after it stops.

[0046] like Figures 1 to 2 As shown, in some embodiments, the cleaning assembly 2 also includes a first driving member 21 and a mounting bracket 24, and the connecting pipe 23 is rotatably connected to the mounting bracket 24, that is, the connecting pipe 23 can be passed through the mounting bracket 24 and can rotate with the mounting bracket 24, and a longer connection end can be formed between the connecting pipe 23 and the mounting bracket 24, which is convenient for stable support of the connecting pipe 23 with a longer axial dimension and reduces excessive vibration of the connecting pipe 23.

[0047] The connecting tube 23 is rotatably disposed between the cleaning member 22 and the mounting bracket 24. Specifically, one end of the connecting tube 23 is rotatably connected to the cleaning member 22, while the other end is rotatably connected to the mounting bracket 24. The first driving member 21 rotates the connecting tube 23, thereby driving the cleaning member 22 to rotate via the connecting tube 23, thereby causing the cleaning member 22 to clean the inner cavity of the screw barrel. The first driving member 21 is fixedly disposed on the mounting bracket 24 so that the first driving member 21 and the mounting bracket 24 move synchronously.

[0048] The first driving member 21 has an output shaft, which is arranged in parallel with the connecting pipe 23 and is transmission-connected to each other. The first driving member 21 can drive the cleaning member 22 to rotate through the connecting pipe 23, which is convenient for reducing the overall axial length of the cleaning assembly 2, and can also provide sufficient sliding support distance between the mounting frame 24 and the connecting pipe 23. Moreover, the output shaft can be connected to the pipe section of the connecting pipe 23 located on the side of the mounting frame 24 close to the cleaning member 22 for transmission, thereby reducing the distance between the transmission connection position and the cleaning member 22, thereby reducing excessive vibration of the cleaning member 22 and ensuring the cleaning effect.

[0049] Optionally, multiple bearings may be provided between the connecting tube 23 and the mounting bracket 24, and the multiple bearings may be spaced apart along the axial direction of the connecting tube 23 so that the mounting bracket 24 can provide multi-point rotational support for the connecting tube 23. Moreover, by providing the bearings, the rotational flexibility between the connecting tube 23 and the mounting bracket 24 can be improved, friction can be reduced, and the connecting tube 23 can be rotated quickly.

[0050] Optionally, the connection between the output shaft and the connecting pipe 23 may be, but is not limited to, a synchronous belt drive or a chain drive, which has high transmission accuracy and avoids slippage.

[0051] like Figures 1 to 2As shown, in some embodiments, a lead screw 41 is rotatably provided on the placement platform 11, that is, both ends of the lead screw 41 are rotatably connected to the placement platform 11. A slider 42 is provided at the bottom of the mounting frame 24, which is threadedly connected to the lead screw 41 and can move along the axial direction of the lead screw 41. A second driving member 43 is provided at the end of the lead screw 41, which can drive the lead screw 41 to rotate. The rotation of the second driving member 43 can drive the lead screw 41 to rotate. The lead screw 41 drives the slider 42 and the mounting frame 24 to move along the axial direction of the lead screw 41 through the connecting thread, thereby driving the cleaning member 22 and the dust collector head 32 to reciprocate in the inner cavity of the screw barrel. The adjustment and use are convenient, and the user's hands are prevented from entering the inner cavity of the screw barrel to operate.

[0052] It should be noted that the lead screw 41 extends along the axial direction of the connecting tube 23, and the axial directions of the connecting tube 23, the screw barrel, and the lead screw 41 can all be in the same direction. Of course, there can also be a certain radial distance or axial angle difference between the three, as long as the connecting tube 23 and the screw barrel do not interfere with each other, and the installation can be adjusted according to actual needs.

[0053] Optionally, both the first drive member 21 and the second drive member 43 can be, but are not limited to, motors, rotary cylinders, or rotary hydraulic cylinders, as long as they can output a rotational force. Alternatively, the second drive member 43 can be a handwheel that can be manually adjusted by the user, allowing the user to manually adjust the position according to the actual cleaning needs of the observed screw barrel, which is more user-friendly.

[0054] like Figures 1 to 2 As shown, in some embodiments, a guide rail 44 can be further provided on the placement platform 11, and the slider 42 is slidably connected to the guide rail 44. The guide rail 44 and the lead screw 41 are both arranged along the axial direction of the connecting tube 23. The guide rail 44 can support the mounting frame 24 by slidingly connecting with the slider 42, and can guide the axial movement of the mounting frame 24 along the lead screw 41, thereby improving the axial motion accuracy of the mounting frame 24, thereby improving the position accuracy of the cleaning member 22 and the screw barrel during the relative movement, and improving the cleaning effect. There are multiple guide rails 44, and multiple guide rails 44 are arranged on both sides of the lead screw 41, so that the mounting frame 24 is evenly stressed on both sides of the lead screw 41 to avoid jamming. Among them, the guide rail 44 and the lead screw 41 can be connected to the same slider 42, or the slider 42 can be provided with multiple guide rails 44 and the lead screw 41 are respectively connected to the slider 42 at different positions.

[0055] In some other embodiments, a limit member is provided at one end of the guide rail 44 close to the cleaning member 22, and the limit member is provided on the movement path of the slider 42. The limit member can define the boundary of the slider 42 to prevent the slider 42 and the mounting frame 24 from detaching from the guide rail 44, and can also prevent the cleaning member 22 from extending into the screw barrel for too long an axial distance. By setting the limit member, the cleaning member 22 can also be protected to prevent the cleaning member 22 from axially colliding with the screw barrel, thereby improving work safety.

[0056] The limiting member may be, but is not limited to, a bump or a card structure, as long as it can limit the position of the slider 42. The lead screw 41, the guide rail 44, the mounting bracket 24 and the slider 42 can all be made of 304 stainless steel.

[0057] like Figures 1 to 2 As shown, in some embodiments, the frame 1 further includes a base 12 and a lifting push rod 13. One end of the lifting push rod 13 is fixedly mounted on the base 12, and the other end is rotatably mounted on the placement platform 11 to reduce stress at the connection and avoid stress concentration. The lifting push rod 13 itself can move up and down the placement platform 11 relative to the base 12, making the lifting and lowering adjustment convenient and easy. During use, the lifting push rod 13 can be adjusted according to the relative height of the cleaning member 22 and the screw barrel, so that the lifting push rod 13 can push the placement platform 11 up and down to push the axis of the cleaning member 22 to a position at the same height as the axis of the screw barrel, so that the cleaning member 22 can be coaxial with the screw barrel, thereby improving the cleaning effect of the cleaning member 22 on the circumferential inner wall of the screw barrel.

The linear bearing can enable the guide rod 111 and the support tube 121 to move axially flexibly and quickly with low friction. The plurality of guide rods 111 and the support tube 121 are arranged circumferentially of the lifting push rod 13. The plurality of guide rods 111 and the plurality of support tubes 121 can be erected and supported circumferentially of the lifting push rod 13, and the placement platform 11 is subjected to uniform force circumferentially of the lifting push rod 13.

[0059] Optionally, the linear bearing is coaxially arranged with the support tube 121 , and mounting grooves may be provided on the side walls of the support tube 121 and / or the guide rod 111 to facilitate the installation of the linear bearing.

[0060] like Figures 1 to 2As shown, in some embodiments, a support frame 122 is fixedly provided on the base 12, and one end of the lifting push rod 13 is fixedly provided on the support frame 122. The support frame 122 can support the lifting push rod 13 from the base 12, provide a basic height for the lifting push rod 13, and reduce the overall height of the lifting push rod 13 itself.

[0061] like Figures 1 to 2 As shown, in some other embodiments, a fisheye joint 131 is provided between the end of the lifting push rod 13 and the base 12, and the fisheye joint 131 is rotatably connected. The fisheye joint 131, also known as a self-lubricating rod end joint bearing, is a component used to connect two rods whose center lines intersect. The main structure of the fisheye joint 131 includes an axis that can rotate around the center line by a certain angle and a joint bearing that can withstand a large load. The outer spherical surface of the inner ring of the fisheye joint 131 can be inlaid with a composite material to achieve the self-lubricating function. The axis and joint bearing of the fisheye joint 131 are connected to the bottom of the placement platform 11, and the other is connected to the lifting push rod 13. The fisheye joint 131 can work normally under large eccentricity and is suitable for low-speed swinging motion, low-speed rotation, and tilting motion within a certain angle range.

The air pipe 33 can be a flexible pipe, one end of the air pipe 33 is connected to the vacuum cleaner 31, and the other end is connected to the connecting pipe 23 to facilitate the transportation of gas and other media between the two.

[0063] like Figures 2 to 4 As shown, in some embodiments, the dust collector head 32 can be disposed on the connecting tube 23. Specifically, the dust collector head 32 includes a fixed tube 321, a plurality of plates 322, and a plurality of connectors 323. The fixed tube 321 is connected to the connecting tube 23. The cleaning member 22 is fixedly disposed on the connecting tube 23 or the fixed tube 321 so that the cleaning member 22 rotates with the connecting tube 23. The plates 322 are disposed on the fixed tube 321, and the plurality of plates 322 are spaced apart along the axial direction of the fixed tube 321. The connectors 323 are disposed between two adjacent plates 322 and can separate the two adjacent plates 322 from each other to form a dust collection channel 324. The dust collection channel 324 is connected to the external environment and to the lumen of the connecting tube 23. The dust collection channel 324 between adjacent plates 322 is connected to the dust collector 31 through the lumen of the connecting tube 23. When the dust collector 31 is activated, a negative pressure is formed in the dust collection channel 324, thereby sucking in impurities in the external environment and achieving a dust collection effect.

[0064] like Figures 2 to 4As shown, in some embodiments, the connecting pipe 23 includes multiple branch pipe sections 231, and adjacent branch pipe sections 231 are detachably connected.

[0065] In some embodiments, the end of the connecting tube 23 is detachably connected to the dust collector head 32 . For example, the end of the connecting tube 23 can be snap-fitted or threadedly connected to the fixing tube 321 to facilitate installation and disassembly of the dust collector head 32 .

[0066] In some embodiments, the end of the connecting tube 23 is detachably connected to the vacuum cleaner 31, and the connection can be, but is not limited to, snap-on, adhesive, bolted, or magnetic, so as to facilitate replacement of vacuum cleaners 31 of different power to form different vacuuming effects.
