Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, and in particular to a roller cleaning device. Background Technology

[0002] After the rollers have been working normally for a period of time, some aluminum powder or dust and other impurities will remain on their surface. If they are not cleaned in time, these impurities will be carried from the roller surface to the surface of the sheet, resulting in the sheet surface cleanliness not meeting the requirements. Moreover, the roller tension will decrease, which will easily cause the sheet surface to slip. The sheet elongation will not meet the requirements and will not be able to meet customer requirements.

[0003] Cleaning while the machine is stopped would disrupt normal production, while cleaning while the machine is running poses significant safety hazards. Most existing cleaning devices use a rotating reciprocating screw to drive the cleaning head in a linear reciprocating motion, with the cleaning head contacting and cleaning the roller surface. However, the pressure between the cleaning head and the roller is relatively constant, meaning the cleaning force is also constant, thus the cleaning effect needs improvement. Summary of the Invention

[0004] To address the challenges and safety risks associated with manual roller cleaning, this invention provides a roller cleaning device. A reciprocating screw drives a cleaning unit to repeatedly clean the roller surface. The contact pressure between the cleaning unit and the roller is adjustable, allowing for adjustments to the cleaning intensity as needed to ensure effective cleaning.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A roller cleaning device is installed between two spaced frames and includes a reciprocating screw, a screw nut, a connecting seat, a drive motor, and a guide rod. The reciprocating screw is rotatably connected to the frame, and the screw nut is engaged on the reciprocating screw. The connecting seat is detachably connected below the screw nut, and the screw nut and the connecting seat move back and forth on the reciprocating screw together.

[0007] The frame is equipped with a drive motor, which is connected to a reciprocating screw for easy control of the screw's operation. The frame is also movably equipped with a guide rod, the installation position of which is adjustable. The guide rod is staggered below the reciprocating screw. A connecting seat is connected downward to the guide rod and slides directly along it. A cleaning unit is elastically connected to one side of the connecting seat, with one end of the cleaning unit pressed against the roller surface to improve the cleaning force on the roller surface.

[0008] Furthermore, each of the two frames is provided with a bearing housing, and the reciprocating screw passes through the two bearing housings to provide reliable support for the reciprocating screw. One end of the reciprocating screw extends out of the bearing housing and is connected to the drive motor through a coupling to facilitate the transmission of power.

[0009] Furthermore, the screw nut includes a horizontal cylinder section, a vertical cylinder section, a fork, an adjusting nut and a small compression spring. The horizontal cylinder section is sleeved on the reciprocating screw and can slide on the reciprocating screw. The vertical cylinder section is connected above the horizontal cylinder section. After the connection and combination of the horizontal cylinder section and the vertical cylinder section, the cross-section is in an "丄" shape.

[0010] Furthermore, the fork is slidably arranged up and down in the vertical cylinder section and rotates relative to the vertical cylinder section. The fork includes a round rod section, a round block section and a guiding section arranged in sequence from top to bottom. The round rod section is a long and thin round rod. The round rod section is fixedly connected to the round block section downward. The round block section is a short and thick round rod. The round block section is fixedly connected to the guiding section downward. The guiding section is a plate body. The lower end surface of the guiding section is bent into an arc shape. The guiding section extends into the thread groove of the reciprocating screw and moves along the thread groove.

[0011] Furthermore, the adjusting nut is threadedly connected to the upper part of the vertical cylinder section. The round rod section penetrates upward through the adjusting nut and is arranged to slide inside the adjusting nut. The small compression spring is sleeved on the round rod section between the adjusting nut and the round block section. The adjusting nut is convenient for changing the compression degree of the small compression spring.

[0012] Furthermore, the guiding optical rod and the reciprocating screw are arranged in parallel. Bearings are arranged at both ends of the guiding optical rod;

[0013] Double groove seats are respectively arranged on the two frames. U-shaped grooves are symmetrically opened on both sides of the double groove seat. The two grooves on both sides are a combining groove and a disengaging groove respectively. The guiding optical rod is arranged between the corresponding combining grooves, or the guiding optical rod is arranged between the corresponding disengaging grooves. The bearings at the ends of the guiding optical rod are clamped in the combining groove or the disengaging groove. It is convenient to install the guiding optical rod at different positions of the double groove seat.

[0014] Furthermore, the cross-section of the connecting seat is an inverted "凵" shape. The connecting seat includes a top plate and side plates. The top plate is bolted to the screw nut. The side plates are fixedly arranged below both sides of the top plate. One side wall of the side plate is recessed inward in an arc shape and abuts against the guiding optical rod, which is convenient for limiting the connecting seat.

[0015] Furthermore, the cleaning unit includes a fixing plate, a sliding rod, a cleaning plate and a large compression spring. The fixing plate is arranged on one side of the connecting seat. The cleaning plates are arranged at intervals above the fixing plate, and the distance between them is adjustable. The cleaning plates are wrapped with cotton yarn adhered with gasoline. The sliding rod is arranged on the cleaning plate. The sliding rod passes through the fixing plate downward and is connected with a mounting nut. The large compression spring is sleeved on the sliding rod between the cleaning plate and the fixing plate.

[0016] Through the above technical solutions, the beneficial effects of the present utility model are:

[0017] This invention uses a drive motor to rotate a reciprocating lead screw. During this rotation, the lead screw nut moves axially along the lead screw. The lead screw nut moves the connecting seat, which in turn moves the cleaning unit. The cleaning unit has an elastic cleaning plate that is pressed tightly against the roller surface by a large compression spring, making elastic contact with the roller surface. Adjusting the compression of the large compression spring changes the contact pressure between the cleaning plate and the roller surface, achieving different cleaning intensities and improving the cleaning effect.

[0018] The guide rod of this invention is installed in a double-groove seat, which has a connecting groove and a separating groove. The guide rod can be installed in the connecting groove, in which case the connecting seat abuts against the guide rod and moves along the guide rod. When the guide rod is installed in the separating groove, the connecting seat disengages from the guide rod, and the connecting seat drives the cleaning unit away from the roller surface, thus ceasing to clean the roller surface.

Detailed implementation manners

[0027] The following will describe the detailed implementation manners of the present utility model in conjunction with the accompanying drawings:

[0028] As Figures 1-7 shown, a roller cleaning device is installed between two frames 1 arranged at intervals. A roller 2 is arranged between the frames 1, and the cleaning device is used to clean the roller 2. The cleaning device includes a reciprocating lead screw 3, a lead screw nut 4, a connecting seat 5, a driving motor 6 and a guiding optical rod 7. The reciprocating lead screw 3 is a prior art. The reciprocating lead screw 3 has two thread grooves with the same pitch and opposite helix directions.

[0029] When the reciprocating lead screw 3 is installed, the reciprocating lead screw 3 is rotatably connected to the frame 1. Specifically, bearing seats 8 are respectively arranged on the two frames 1, and the reciprocating lead screw 3 passes through between the two bearing seats 8, and the reciprocating lead screw 3 can rotate freely.

[0030] In order to drive the reciprocating lead screw 3, a driving motor 6 is arranged on one frame 1, and the driving motor 6 is connected to the reciprocating lead screw 3. Specifically, one end of the reciprocating lead screw 3 extends out of the bearing seat 8 and is connected to the driving motor 6 through a coupling 9. The driving motor 6 adopts a hydraulic motor, and the operation of the reciprocating lead screw 3 can be controlled through the driving motor 6.

[0031] A lead screw nut 4 is engaged on the reciprocating lead screw 3; through the rotation of the reciprocating lead screw 3, the lead screw nut 4 can be urged to perform an axial reciprocating motion. The lead screw nut 4 includes a horizontal cylinder section 10, a vertical cylinder section 11, a fork 12, an adjusting nut 13 and a small compression spring 14. The horizontal cylinder section 10 is sleeved on the reciprocating lead screw 3, and a vertical cylinder section 11 is communicated above the horizontal cylinder section 10. After the horizontal cylinder section 10 and the vertical cylinder section 11 are connected and combined, the cross section is in the shape of "丄".

[0032] The fork 12 is slidably arranged in the vertical cylinder section 11. The fork 12 can slide up and down relative to the vertical cylinder section 11, and the fork can rotate relative to the vertical cylinder section 11. In this embodiment, the fork includes a round rod section 121, a round block section 122 and a guiding section 123 arranged in sequence from top to bottom. The round rod section 121 is in the shape of a long and thin round rod, and the round rod section 121 is fixedly connected to the round block section 122 downward. The round block section 122 is in the shape of a short and thick round rod, and the diameter of the round block section 122 is adapted to the inner diameter of the vertical cylinder section 11.

[0033] The circular block segment 122 is fixedly connected downward to the guide segment 123, which is a plate with its lower end face bent into an arc shape. The guide segment 123 extends into the thread groove of the reciprocating screw 3 and moves along the thread groove. During the rotation of the reciprocating screw 3, the side of the thread groove pushes the guide segment 123 placed in the thread groove to reciprocate, thereby driving the entire screw nut 4 to reciprocate along the axial direction of the reciprocating screw 3.

[0034] The adjusting nut 13 inside the lead screw nut 4 is threadedly connected to the upper part of the vertical cylinder section 11. The adjusting nut 13 is a stepped shaft shape. The round rod section 121 passes upward through the adjusting nut 13 and slides inside the adjusting nut 13. A small compression spring 14 is sleeved on the round rod section 121 between the adjusting nut 13 and the round block section 122. Tightening the adjusting nut 13 causes it to move downward, which compresses the small compression spring 14, and the small compression spring 14 applies a larger force to the shift fork.

[0035] A guide rod 7 is also movably mounted on the frame 1, and the installation position of the guide rod 7 is adjustable. The guide rod 7 is staggered below the reciprocating lead screw 3, and the guide rod 7 and the reciprocating lead screw 3 are arranged in parallel. Bearings 15 are provided at both ends of the guide rod 7.

[0036] During installation, the guide rod 7 is accompanied by double-groove seats 16 on both frames 1. The double-groove seats 16 have symmetrically arranged U-shaped grooves on both sides, with overlap between the grooves. The grooves on both sides are respectively a connecting groove 161 and a disengaging groove 162, resulting in an overlap between the connecting groove 161 and the disengaging groove 162. The connecting groove 161 and the disengaging groove 162 are at the same height, with the connecting groove 161 closer to the roller 2 and the disengaging groove 162 further away from the roller 2.

[0037] The widths of the connecting groove 161 and the disengaging groove 162 are adapted to the diameter of the bearing 15 at the end of the guide rod 7, and the thicknesses of the connecting groove 161 and the disengaging groove 162 are adapted to the thickness of the bearing 15. Guide rods 7 are arranged between corresponding connecting grooves 161 or between corresponding disengaging grooves 162, with the bearing 15 at the end of the guide rod 7 engaging within the connecting groove 161 or the disengaging groove 162. That is, the guide rod 7 can be installed in either the connecting groove 161 or the disengaging groove 162. When placed in the connecting groove 161, the guide rod 7 is in a working state; when placed in the disengaging groove 162, the guide rod 7 is in a non-working state.

[0038] A connecting seat 5 is detachably connected below the lead screw nut 4. The connecting seat 5 has an inverted "U" shaped cross section and includes a top plate 51 and a side plate 52. The top plate 51 is bolted to the lead screw nut 4, and the side plates 52 are fixedly installed on the lower sides of both sides of the top plate 51.

[0039] The connecting seat 5 is connected downward to the guide light rod 7 and slides directly along the guide light rod 7. Here, one side wall of the side plate 52 is recessed inward in an arc shape and abuts against the guide light rod 7 in the working state, restricting the rotation of the connecting seat 5.

[0040] A cleaning unit 17 is elastically connected to one side of the connecting seat 5, with one end of the cleaning unit 17 pressed tightly against the surface of the roller 2. The cleaning unit 17 includes a fixing plate 171, a sliding rod 172, a cleaning plate 173, and a large compression spring 174. The fixing plate 171 is located on one side of the connecting seat 5, specifically between the two side plates 52. Cleaning plates 173 are arranged at intervals above the fixing plate 171. The cleaning plates 173 are arc-shaped and are wrapped with cotton yarn that has been coated with gasoline.

[0041] When the cleaning plate 173 is connected to the fixed plate 171, a sliding rod 172 is provided on the cleaning plate 173. The sliding rod 172 passes downward through the fixed plate 171 and is connected to a mounting nut 175. The sliding rod 172 and the cleaning plate 173 can slide together relative to the fixed plate 171. A large compression spring 174 is sleeved on the sliding rod 172 between the cleaning plate 173 and the fixed plate 171. Under the action of the large compression spring 174, the cleaning plate 173 moves away from the fixed plate 171 and presses tightly against the roller 2.

[0042] By tightening the mounting nut 175, the degree of extension and retraction of the large compression spring 174 can be changed. By extending and retracting the spring, the contact pressure between the cleaning plate 173 and the roller 2 is changed, thereby adjusting the cleaning force.

[0043] The principle of this invention is as follows: The guide rod 7 is installed in the connecting groove 161 to ensure that the guide rod 7 is in working condition. At this time, the connecting seat 5 abuts against the guide rod 7, and the cleaning plate 173 on the connecting seat 5 is pressed tightly against the surface of the roller 2 under the action of the large compression spring 174. When the cleaning device is in use, the drive motor 6 transmits power to the reciprocating screw 3 through the coupling 9, causing the reciprocating screw 3 to rotate. The screw nut 4 on the reciprocating screw 3 makes linear reciprocating motion, and the connecting seat 5 moves together. The cleaning unit 17 is driven by the connecting seat 5 to move reciprocally on the surface of the roller 2, and the cleaning plate 173 is used to clean the surface of the roller 2.

[0044] The above cleaning process can be performed at any time while the roller 2 is running, without affecting normal production. Moreover, the automatic mechanical cleaning ensures the safety of the workers. When cleaning is not required for a long time, the guide rod 7 can be moved into the disengagement groove 162. At this time, the connecting seat 5 no longer abuts against the guide rod 7, the connecting seat 5 deflects to a certain extent and maintains balance under its own weight. At this time, the cleaning plate 173 is disengaged from the surface of the roller 2, and the lead screw nut 4 no longer contacts the roller surface, thus eliminating the need for cleaning the roller surface.

[0045] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
