Description

Technical Field

[0001] This invention relates to the field of roll cleaning, and more specifically, to an adjustable scraper for cleaning roll grooves. Background Technology

[0002] During continuous production, the die accumulates residual metal shavings, particles, and release agents during demolding. These impurities in the roll grooves affect the demolding effect and the width of the composite strip after demolding. When two metals are laminated, these residues pose a risk of entrapment, contaminating the interface and affecting the lamination effect, potentially leading to substandard product performance and significant quality risks. Currently, continuous manual cleaning of the roll grooves with utility blades is necessary, posing safety hazards and proving inconvenient and ineffective. Therefore, it is necessary to design and develop a scraper structure that can clean the roll grooves during production, keeping the groove surface clean and free of foreign matter to ensure unaffected product quality. Summary of the Invention

[0003] 1. Technical problems to be solved

[0004] To address the problems existing in the prior art, the purpose of this invention is to provide an adjustable scraper for cleaning the grooves of rolls, which can scrape away foreign objects on three surfaces of the inner wall of the roll groove, and the tightness can be freely adjusted, so as to achieve a stable cleaning effect for different groove sizes.

[0005] 2. Technical Solution

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] An adjustable scraper for cleaning the grooves of a roll includes a roll body with grooves. A cleaning mechanism for removing residue from the grooves is mounted on the outer side of the roll body. The cleaning mechanism includes two mounting seats, with a connecting plate fixedly connected between them. Each mounting seat has two limiting holes, and a limiting shaft is inserted into each limiting hole. A first scraper is fixedly connected to the end of the two limiting shafts near the left side away from the limiting holes, and a second scraper is fixedly connected to the end of the two limiting shafts near the right side away from the limiting holes. A first screw is screwed onto the mounting seat near the left side, and the first screw abuts against the outer wall of the second scraper. A second screw is screwed onto the mounting seat near the right side, and the second screw abuts against the outer wall of the first scraper. A third screw is screwed onto the connecting plate. A spring is mounted on the end of the third screw near the roll body, and a third scraper is fixedly connected to the other end of the spring. The end of the third scraper away from the spring is attached to the roll body. On the bottom surface of the inner wall of the main body groove, the first scraper and the second scraper are respectively attached to the left and right sides of the inner wall of the roller body groove near the roller body. By rotating the first screw, the first screw moves towards the first scraper and squeezes the first scraper to move to the right side of the inner wall of the roller body groove and fits tightly. By rotating the second screw, the second screw moves towards the second scraper and squeezes the second scraper to move to the left side of the inner wall of the roller body groove and fits tightly. By rotating the connecting plate, the connecting plate moves towards the third scraper and squeezes the spring to push the third scraper, so that one end of the third scraper fits against the bottom surface of the inner wall of the roller body groove. By adjusting the first screw, the second screw and the connecting plate, the first scraper, the second scraper and the third scraper can be controlled to thoroughly clean and scrape the residue on the left and right sides and the bottom surface of the inner wall of the roller body groove. This not only has a good cleaning effect, but can also be freely adjusted according to the size of the groove, and avoids the safety hazards of cleaning with a utility knife.

[0008] Furthermore, the first screw, the second screw, and the connecting plate are all fixedly connected to a rotating block that is compatible with them at the ends away from the groove of the roll body, and the rotating block is provided with a hexagonal groove. By setting the rotating block and the hexagonal groove, it is possible to facilitate technicians to quickly adjust the first screw, the second screw, and the connecting plate manually or with tools.

[0009] Furthermore, each of the two mounting bases has two slots at its bottom for adjusting the position of the mounting base. By using mounting bolts, when the bolts pass through the slots, the position of the mounting base during installation can be adjusted according to the length of the slots.

[0010] Furthermore, each of the two mounting bases has two through holes on its upper surface, and the bottom ends of the two through holes are respectively connected to two limiting holes on the corresponding mounting base. The inner wall of the through hole near the top is provided with a threaded groove, and the inner wall of the through hole near the bottom is a smooth surface. An abutment block is slidably connected to the smooth surface of the through hole near the bottom. A threaded shaft is screwed onto the inner wall of the through hole near the top, and the threaded shaft is screwed onto the abutment block. The lower surface of the abutment block abuts against the outer surface of the limiting shaft located in the limiting hole. By rotating the threaded shaft, the threaded shaft moves downward and pushes the abutment block to abut against the top of the limiting shaft, thereby improving the stability of the limiting shaft in the limiting hole, and thus enhancing the stability of the first scraper and the second scraper in the groove of the roll body.

[0011] Furthermore, the lower surface of the abutment block is provided with an arc-shaped groove that matches the arc-shaped contour of the limiting shaft, and the arc-shaped groove engages with the top of the limiting shaft. By providing an arc-shaped groove on the lower surface of the abutment block that matches the arc-shaped contour of the limiting shaft and engages with the top of the limiting shaft, the stability of the limiting shaft within the limiting hole can be further improved, thereby enhancing the stability of the first scraper and the second scraper within the groove of the roll body.

[0012] Furthermore, the inner wall of the arc-shaped groove is bonded with an anti-slip block, and the anti-slip block is made of rubber. The rubber anti-slip block can further improve the stability of the limiting shaft in the limiting hole, thereby enhancing the stability of the first scraper and the second scraper in the groove of the roll body.

[0013] Furthermore, two limiting blocks are fixedly connected to one side of the connecting plate relative to the roll body, and each of the two limiting blocks has a sliding groove adapted to the third scraper on its opposite side. The opposite sides of the third scraper are limited and slidably connected in the two sliding grooves. By having sliding grooves adapted to the third scraper on the opposite sides of the two limiting blocks, and the opposite sides of the third scraper being limited and slidably connected in the two sliding grooves, the stability of the third scraper in the groove of the roll body can be improved.

[0014] Furthermore, both the first and second scrapers are equipped with pressure sensors. Multiple mounting slots are provided on the side of each scraper that is in contact with the inner wall of the roll body groove. A monitoring ball is installed in each mounting slot, with one side of the monitoring ball protruding outside the mounting slot and the other side fixedly connected to multiple spring wires. The end of each spring wire away from the monitoring ball is fixedly connected to the mounting slot. Pressure sensors are also provided on both the first and second scrapers. Each pressure sensor has a sensing end corresponding to one of the mounting slots, and the sensing end is located within the mounting slot. The pressure sensor is connected to an external alarm. Multiple sensing ends and one side of the monitoring ball on the pressure sensor protrude outside the mounting groove. When the monitoring ball on the side of the first and second scrapers is tightly connected to the inner wall of the groove in the roll body, the monitoring ball will be squeezed and stick to the sensing end. At this time, the pressure of the pressure sensor is in a safe state. When one side of the first or second scraper detaches, the corresponding monitoring ball will detach from the sensing end. At this time, the pressure sensor will send a signal to the external alarm, and the external alarm will sound an alarm to remind technicians to adjust the distance between the first and second scrapers and the groove in the roll body in time to improve the cleaning effect.

[0015] Furthermore, the monitoring ball includes a first hemisphere and a second hemisphere. The first hemisphere is a solid hemispherical shell, and the second hemisphere is a hollow hemispherical shell. Liquid lubricating oil is filled between the second hemisphere and the first hemisphere. Multiple oil outlet holes are provided on the second hemisphere. By filling the space between the second hemisphere and the first hemisphere with liquid lubricating oil and providing multiple oil outlet holes on the second hemisphere, the inner wall of the groove can be lubricated when the monitoring ball is in contact with the inner wall of the groove, thereby reducing damage to the inner wall of the groove.

[0016] Furthermore, an absorbent layer is adhered to the inner wall of the second hemisphere. The absorbent layer is made of sponge. By fixing the absorbent layer made of sponge to the inner wall of the second hemisphere, a large amount of lubricating oil can be prevented from flowing out, allowing the lubricating oil to flow out slowly and improving the lubrication effect.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of this invention are:

[0019] (1) This solution rotates the first screw, causing it to move towards the first scraper and press the first scraper to move towards the right side of the inner wall of the roll body groove and fit tightly. By rotating the second screw, the second screw moves towards the second scraper and presses the second scraper to move towards the left side of the inner wall of the roll body groove and fits tightly. By rotating the connecting plate, the connecting plate moves towards the third scraper and compresses the spring to push the third scraper, thereby causing one end of the third scraper to fit against the bottom surface of the inner wall of the roll body groove. By adjusting the first screw, the second screw, and the connecting plate, the first scraper, the second scraper, and the third scraper can be controlled to thoroughly clean and scrape the residue on the left and right sides and the bottom surface of the roll body groove. This not only provides a good cleaning effect but also allows for free adjustment according to the size of the groove. It also avoids the safety hazards of manually cleaning with a utility knife.

[0020] (2) This solution rotates the threaded shaft, causing its threaded shaft to move downwards and push the abutment block to abut against the top of the limiting shaft, thereby improving the stability of the limiting shaft in the limiting hole, and thus enhancing the stability of the first scraper and the second scraper in the groove of the roll body. The lower surface of the abutment block is provided with an arc groove that matches the arc contour of the limiting shaft, and the arc groove is engaged with the top of the limiting shaft, which can further improve the stability of the limiting shaft in the limiting hole, and thus enhance the stability of the first scraper and the second scraper in the groove of the roll body.

[0021] (3) In this solution, multiple sensing ends on the pressure sensor and one side of the monitoring ball protruding outside the mounting groove are used. When the side of the first and second scrapers with the monitoring ball is tightly connected to the inner wall of the groove of the roll body, the monitoring ball will be squeezed and stick to the sensing end. At this time, the pressure of the pressure sensor is in a safe state. When one side of the first or second scraper is separated, the corresponding monitoring ball will be separated from the sensing end. At this time, the pressure sensor will send a signal to the external alarm, and the external alarm will sound an alarm to remind technicians to adjust the distance between the first and second scrapers and the groove of the roll body in time to improve the cleaning effect.

[0022] (4) This solution uses liquid lubricating oil to fill the space between the second hemisphere and the first hemisphere, and the second hemisphere has multiple oil outlet holes. This can achieve the effect of lubricating the inner wall of the groove when the monitoring ball is in contact with the inner wall of the groove, reducing the damage to the inner wall of the groove. The absorbent layer of sponge material is fixedly connected to the inner wall of the second hemisphere, which can prevent a large amount of lubricating oil from flowing out and allow the lubricating oil to flow out slowly, thus improving the lubrication effect.

[0023] (5) This solution, through the setting of the rotating block and the hexagonal groove, can facilitate technicians to quickly adjust the first screw, the second screw and the connecting plate by manual or tool. By installing the bolt, when the bolt passes through the slot, the length of the slot can be used to adjust the position of the mounting seat during installation. Attached Figure Description

By rotating the second screw 4, the second screw 4 moves towards the second scraper 2 and squeezes the second scraper 2 to move to the left side of the inner wall of the groove of the roll body 16 and fits it tightly. By rotating the connecting plate 9, the... The connecting plate 9 moves towards the third scraper 7 and compresses the spring 5 to push the third scraper 7, thereby making one end of the third scraper 7 fit against the bottom surface of the inner wall of the groove of the roll body 16. By adjusting the first screw 3, the second screw 4 and the connecting plate 9, the first scraper 1, the second scraper 2 and the third scraper 7 can be controlled to thoroughly clean and scrape the residue on the left and right sides and the bottom surface of the groove of the roll body 16. This not only has a good cleaning effect, but can also be freely adjusted according to the size of the groove, while avoiding the safety hazards of cleaning with a utility knife.

[0039] The first screw 3, the second screw 4, and the connecting plate 9 are all fixedly connected to a rotating block 8 at the end away from the groove of the roll body 16. The rotating block 8 is provided with a hexagonal groove. By setting the rotating block 8 and the hexagonal groove, it is possible to facilitate technicians to quickly adjust the first screw 3, the second screw 4, and the connecting plate 9 manually or with tools.

[0040] The bottom of each of the two mounting bases 10 has two slots 28 for adjusting the position of the mounting base 10. By using mounting bolts, when the bolts pass through the slots 28, the position of the mounting base 10 during installation can be adjusted according to the length of the slots 28.

[0041] Two through holes are provided on the upper surface of each of the two mounting bases 10, and the bottom ends of the two through holes are respectively connected to two limiting holes 12 on the corresponding mounting bases 10. A threaded groove is provided on the inner wall of the through hole near the top, and the inner wall of the through hole near the bottom is a smooth surface. An abutment block 14 is slidably connected to the smooth surface of the through hole near the bottom. A threaded shaft 13 is screwed on the inner wall of the through hole near the top, and the threaded shaft 13 is screwed to the abutment block 14. The lower surface of the abutment block 14 abuts against the outer surface of the limiting shaft 11 located in the limiting hole 12. By rotating the threaded shaft 13, the threaded shaft 13 moves downward and pushes the abutment block 14 to abut against the top of the limiting shaft 11, thereby improving the stability of the limiting shaft 11 in the limiting hole 12, and thus enhancing the stability of the first scraper 1 and the second scraper 2 in the groove of the roll body 16.

[0042] The lower surface of the abutment block 14 is provided with an arc-shaped groove that matches the arc-shaped contour of the limiting shaft 11, and the arc-shaped groove is engaged with the top of the limiting shaft 11. By providing an arc-shaped groove on the lower surface of the abutment block 14 that matches the arc-shaped contour of the limiting shaft 11 and is engaged with the top of the limiting shaft 11, the stability of the limiting shaft 11 within the limiting hole 12 can be further improved, thereby enhancing the stability of the first scraper 1 and the second scraper 2 within the groove of the roll body 16.

[0043] The inner wall of the arc groove is bonded with an anti-slip block 15, and the anti-slip block 15 is made of rubber. The anti-slip block 15 made of rubber can further improve the stability of the limiting shaft 11 in the limiting hole 12, thereby enhancing the stability of the first scraper 1 and the second scraper 2 in the groove of the roll body 16.

[0045] Pressure sensors are installed in both the first scraper 1 and the second scraper 2. Multiple mounting slots 20 are provided on the side of the first scraper 1 and the second scraper 2 that are in contact with the inner wall of the groove in the roll body 16. A monitoring ball 23 is installed in each mounting slot 20.

The end of the spring wire 21 away from the monitoring ball 23 is fixedly connected to the mounting slot 20. Pressure sensors 19 are installed on both the first scraper 1 and the second scraper 2. Each pressure sensor 19 has a sensing end 22 corresponding to one of the mounting slots 20, and the sensing end 22 is located within the mounting slot 20. The pressure sensor 19 is connected to an external alarm. Multiple sensing ends 22 and one side of the monitoring ball 23 on the pressure sensor 19 protrude outside the mounting groove 20. When the side of the first scraper 1 and the second scraper 2 with the monitoring ball 23 is tightly connected to the inner wall of the groove of the roll body 16, the monitoring ball 23 will be squeezed and stick to the sensing end 22. At this time, the pressure of the pressure sensor 19 is in a safe state. When one side of the first scraper 1 or the second scraper 2 is disengaged, the corresponding monitoring ball 23 will be disengaged from the sensing end 22. At this time, the pressure sensor 19 will send a signal to the external alarm, and the external alarm will sound an alarm to remind technicians to adjust the distance between the first scraper 1 and the second scraper 2 and the groove of the roll body 16 in time to improve the cleaning effect.

[0046] The monitoring ball 23 includes a first hemisphere 24 and a second hemisphere 26.

Liquid lubricating oil is filled between the second hemisphere 26 and the first hemisphere 24. Multiple oil outlet holes 25 are provided on the second hemisphere 26. By filling the space between the second hemisphere 26 and the first hemisphere 24 with liquid lubricating oil and providing multiple oil outlet holes 25 on the second hemisphere 26, the inner wall of the groove can be lubricated when the monitoring ball 23 is in contact with the inner wall of the groove, thereby reducing damage to the inner wall of the groove.

[0047] An absorbent layer 27 is adhered to the inner wall of the second hemisphere 26. The absorbent layer 27 is made of sponge. The sponge absorbent layer 27 is fixedly connected to the inner wall of the second hemisphere 26, which can prevent the lubricating oil from flowing out in large quantities and allow the lubricating oil to flow out slowly, thereby improving the lubrication effect.
