Description

Technical Field

[0001] The present invention discloses an auxiliary paper pressing device for the working surface of a roll, belonging to the technical field of roll rust prevention. Background Art

[0002] Rolls are important components that are consumed in large quantities in steel rolling production. The quality of the rolls not only affects the surface quality of the rolled products, but also affects the operating rate of the rolling mill. After use and during transportation, etc., the rolls need to be maintained and stored. Otherwise, rust is likely to occur on the surface, affecting their normal use. Currently, for the maintenance of rolls, most often an anti-rust oil is coated and then a layer of anti-rust paper is manually wrapped on the outer layer to prevent the loss of the anti-rust oil for the storage of the rolls. Actually, the connecting parts at both ends of the roll are placed on the brackets, and the roll is rotated by an external force to achieve the purpose of oil coating and paper wrapping. Due to the large length of the working surface of the roll, this method results in poor adhesion between the anti-rust paper and the roll surface, easy loss of the anti-rust oil, leading to poor maintenance effect, poor sealing performance, poor corrosion resistance, and short storage time. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the existing manual paper wrapping has a large gap, and after long-term placement, the anti-rust paper is separated from the roll, resulting in serious corrosion of the roll.

[0004] The technical solution adopted by the present invention to solve its technical problem is: an auxiliary paper pressing device for the working surface of a roll, including a Y-shaped fixing frame. The fixing frame includes a movable arm and a frame body. One end of the movable arm is hinged to the middle of the frame body, and the angle between the movable arm and the frame body can be fixed. Auxiliary rollers are hinged to the upper ends of both the movable arm and the frame body, and the angles between the auxiliary rollers and the movable arm and the frame body can be fixed.

[0005] Among them, the above device includes a telescopic adjusting rod, and both ends of the adjusting rod are respectively hinged to the movable arm and the frame body.

[0006] Further, in the above device, the adjusting rod is a cylinder, the cylinder body of the cylinder is hinged to the middle of the frame body, and the air rod of the cylinder is hinged to the middle of the movable arm.

[0007] Among them, in the above device, the auxiliary roller includes a fixing member with a trapezoidal structure, a connecting belt, and two cylindrical roller bodies arranged at intervals. The two roller bodies are connected by the connecting belt. The small ends of the fixing member are respectively hinged to the upper ends of the movable arm or the frame body, and the angles between the fixing member and the corresponding movable arm and the frame body can be fixed. The roller bodies are hinged to both end parts on the large end side of the fixing member.

[0008] Further, the above device further includes a locking member, and the angle between the fixing member and the upper end parts of the corresponding movable arm and the frame body can be adjusted by the locking member.

[0009] Furthermore, the above-mentioned device further includes a buffer elastic member, which is arranged at the hinge joint between the roller body and the fixing member, enabling the roller body to reciprocate radially along the hinge axis on the fixing member.

[0010] Among them, the above-mentioned device further includes a bracket and an angle adjusting member. The lower end of the frame body is hinged to the upper end surface of the bracket. The angle adjusting member is a telescopic structure. One end of the angle adjusting member is hinged to the bracket, and the other end is hinged to the side wall of the frame body.

[0011] Furthermore, in the above-mentioned device, the angle adjusting member is a cylinder. The end of the cylinder body is hinged to the upper end surface of the bracket, and the rod body of the cylinder is hinged to the middle and lower part of the frame body.

[0012] Furthermore, the above-mentioned device further includes a pressing block for paper feeding. The pressing block is arranged at the paper outlet of the paper feeder. The lower end surface of the pressing block is horizontally arranged and can be coplanar with the upper end surface of the connecting belt of the movable arm.

[0013] The beneficial effects of the present invention are as follows: The structure of this device is simple and easy to manufacture. During actual use, by adjusting the included angle between the movable arm and the frame body, the auxiliary roller hinged at the upper end is kept in contact with the rust-proof paper on the surface of the rolling mill roll. When an external force is applied to the rolling mill roll to make it rotate, the rust-proof paper is wrapped on the outside. Since the auxiliary roller is in contact with the rust-proof paper on the surface of the rolling mill roll, the rust-proof paper is in good contact with the working surface of the rolling mill roll, ensuring that the rust-proof paper is closely attached to the working surface of the rolling mill roll through the rust-proof oil, thereby preventing the rust-proof oil from falling off and affecting the working surface of the rolling mill roll.

Therefore, there should be certain requirements for the angles of the auxiliary rollers 93. So, in this device, it is preferred that the included angles between the movable arm 91, the frame body 9 and the corresponding auxiliary rollers 93 can be fixed to ensure that the contact surface of the auxiliary rollers 93 is always in good contact with the rust-proof paper 11. The structural form of the frame body 9 is not fixed and can be specifically made according to the actual on-site installation conditions. The frame body 9 can be directly placed or hinged on the ground or the bracket 1. Since the working surface length of the roll 3 is relatively long, the auxiliary rollers 93 can be in a cylindrical structure or a plurality of them arranged at intervals are also acceptable.

[0021] Preferably, the above device includes a telescopic adjusting rod 94. The two ends of the adjusting rod 94 are respectively hinged to the movable arm 91 and the frame body 9. Those skilled in the art can understand that in this device, it is preferred that the included angle between the movable arm 91 and the frame body 9 is adjusted by the adjusting rod 94. Specifically, the adjusting rod 94 is preferably a telescopic structure, that is, the length of the adjusting rod 94 is adjustable. Actually, the two ends of the adjusting rod 94 are respectively hinged to the movable arm 91 and the frame body 9, so that the purpose of adjusting the included angle between the movable arm 91 and the frame body 9 can be achieved by extending or shortening the adjusting rod 94.

[0022] Preferably, in the above device, the adjusting rod 94 is a cylinder. The cylinder body of the cylinder is hinged to the middle of the frame body 9, and the air rod of the cylinder is hinged to the middle of the movable arm 91. Those skilled in the art can understand that in this device, it is only preferred that the adjusting rod 94 is a cylinder. Actually, the cylinder body of the cylinder is hinged to the middle of the frame body 9, and the air rod of the cylinder is hinged to the middle of the movable arm 91. By setting sensors, the included angle between the movable arm 91 and the frame body 9 can be accurately adjusted to ensure that the contact surface of the auxiliary rollers 93 accurately contacts the rust-proof paper 11 and ensure that the rust-proof paper 11 is in contact with the working surface of the roll 3.

[0023] Preferably, in the above-mentioned device, the auxiliary roller 93 includes a fixing member 934 with a trapezoidal structure, a connecting belt 932, and two cylindrical roller bodies 931 arranged at intervals. The two roller bodies 931 are connected by the connecting belt 932. The small ends of the fixing member 934 are respectively hinged to the movable arm 91 or the upper end of the frame 9, and the angles between the fixing member 934 and the corresponding hinged movable arm 91 and frame 9 can be fixed.

The hinge shaft can be preferably set as a screw structure, and the pre-tightening of the fixing member 934 and the movable arm 91, and the fixing member 934 and the frame 9 is realized by screwing in the nut to fix the angle between the fixing member 934 and the movable arm 91, and the fixing member 934 and the frame 9.

[0025] Preferably, the above-mentioned device further includes a buffer elastic member 933. The buffer elastic member 933 is arranged at the hinge joint between the roller body 931 and the fixing member 934, so that the roller body 931 can reciprocate along the radial direction of the hinge shaft on the fixing member 934. Those skilled in the art can understand that in order to reduce the impact of the rolling roller 3 during work on the auxiliary roller 93, the buffer elastic member 933 is preferably arranged at the hinge joint between the roller body 931 and the fixing member 934 of this device. At the same time, under the elastic force of the buffer elastic member 933, the roller body 931 can reciprocate along the radial direction on the fixing member 934, and the impact is buffered through the elastic deformation of the buffer elastic member 933.

[0026] Preferably, the above-mentioned device further includes a bracket 1 and an angle adjusting member 92. The lower end of the frame body 9 is hinged to the upper end surface of the bracket 1.

The lower end surface of the pressing block 6 is horizontally arranged and can be coplanar with the upper end surface of the connecting belt 932 of the movable arm 91. Those skilled in the art can understand that, at present, in order to improve the operation efficiency, the existing paper feeder 5 is used to wrap the rust-proof paper 11. However, since the rust-proof paper 11 in the paper feeder 5 is in rolls, it is easy to cause the end of the rust-proof paper 11 not to directly contact the surface of the roller 3. Therefore, the device preferably sets a pressing block 6 for paper feeding of the rolled paper at the paper outlet of the paper feeder 5. Under the action of the pressing block 6, it is ensured that the end of the rust-proof paper 11 is a flat structure and directly contacts the rust-proof oil coated on the working surface of the roller 3, so as to achieve the purpose of quickly wrapping the rust-proof paper 11 on the working surface of the roller 3.
