Description

Technical Field

[0001] The utility model belongs to the technical field of steel strip coiling liner paper, and particularly relates to an automatic pickling paper feeding and cutting device. Background Technique

[0002] When cold-rolled steel is coiled, a layer of liner paper needs to be padded to protect the surface. When we carry out subsequent processing operations such as slitting and strip cutting on the steel coil, it is necessary to unwind the liner paper using an unwinding device. The current liner paper unwinding mechanism includes a steel strip roller, a guiding roller, and an unwinding roller. The steel strip roller unwinds and stacks the steel strip and the liner paper on the surface of the steel strip at the same time. However, during the unwinding process of the liner paper, when the steel strip on the steel strip roller is unwound, it is necessary to cut the output part of the paper feeding of the liner paper. In the prior art, the liner paper is directly cut by a cutter, and there is no setting to press and fix one end of the cut liner paper, which easily causes the liner paper to break away after cutting, making the coiled liner paper become relatively loose and there is a phenomenon of deviation due to the lack of paper feeding output tension. This cutting method will affect the progress of the liner paper unwinding and conveying. Content of the Utility Model

[0003] The purpose of the utility model is to provide an automatic pickling paper feeding and cutting device to solve the problems put forward in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: an automatic pickling paper feeding and cutting device, including an installation steel frame, and a unwinding frame for sending out a coiled paper is arranged at the bottom end inside the installation steel frame. A tension guiding roller for guiding and outputting the paper output from the unwinding frame is inclined at the upper end inside the installation steel frame. A unwinding paper support cutting plate for pressing and cutting the paper to be sent and cut is inclined at the corresponding bottom side of the tension guiding roller and inside the installation steel frame. A paper cutting installation plate part for installing a pneumatic cutting mechanical part for the unwinding paper is inclined at one side of the top end inside the installation steel frame. A pneumatic pressing roller for pressing and assisting in cutting the unwinding paper is pneumatically telescoped on one side of the paper cutting installation plate part. A sending and cutting blade for cutting the unwinding paper is arranged on one side of the installation frame of the pneumatic pressing roller.

[0005] Preferably, an installation seat is arranged on one side inside the installation steel frame, a connecting frame is arranged inside the installation seat, and the connecting frame is connected to one end of the unwinding frame through a pin shaft connecting part to achieve stable support for one end of the unwinding shaft rod.

[0006] Preferably, positioning roller wheels are arranged on both inner sides of the V-shaped notch opened at one end of the unwinding frame, and a unwinding shaft rod arranged on one side inside the installation steel frame is positioned between the positioning roller wheels and rotatably installed thereon. A paper roll body is sleeved on the unwinding shaft rod to achieve stable conveying of the coiled liner paper.

[0007] Preferably, guide slide bars are fixed at both ends of the fixed frame of the pneumatic pressing roller, and a limit fixing block for limiting the stroke of the guide slide bars is provided at the other end of the guide slide bars, which can ensure the accuracy of paper feeding and cutting during the telescopic movement of the pneumatic pressing roller.

[0008] Preferably, a tool holder with an L-shaped structure is provided on one side of the fixed frame of the pneumatic pressing roller. One end of the paper feeding and cutting blade is fixed on the tool holder and is vertically corresponding to the pneumatic pressing roller, which can simultaneously press and feed the conveyed lining paper for cutting.

[0009] Preferably, a cylinder is provided in the middle of one side of the paper cutting mounting plate. One end of the piston rod of the cylinder is fixed on the bracket in the pneumatic pressing roller, and fixed guide blocks are symmetrically provided on both sides of the cylinder. The fixed guide blocks are movably sleeved on the guide slide bars for guiding and positioning, which can accurately press the pneumatic pressing roller on the surface of the lining paper and ensure the accuracy of cutting.

[0010] Preferably, embedding holes are evenly provided on the surface of the unwinding paper supporting cutting plate, and rubber ball parts are movably embedded in the embedding holes, which can reduce the friction between the lining paper and the edge of the unwinding paper supporting cutting plate.

[0011] Compared with the prior art, the technical effects and advantages of the present utility model are as follows: In this pickling automatic paper feeding and cutting device, through the installation combination of the pneumatic pressing roller, the paper feeding and cutting blade, the guide slide bars, the tool holder, the cylinder, and the fixed guide blocks on the paper cutting mounting plate and the cooperation with the unwinding paper supporting cutting plate, the roll paper body on the unwinding shaft can be unwound obliquely upward by using the tension guide roller, and the lining paper passes through the unwinding supporting cutting plate. When the lining paper needs to be fed and cut, the cylinder pushes the pneumatic pressing roller to move obliquely downward, and the tool holder and the paper feeding and cutting blade follow the movement. After the paper feeding and cutting blade contacts the lining paper, the pneumatic pressing roller closely presses the lining paper on the surface of the unwinding paper supporting cutting plate, so that the lining paper can be pressed and positioned on the unwinding paper supporting cutting plate before being cut, preventing the wound lining paper from falling off after being cut, making the relatively tight wound lining paper become relatively loose without tension, and thus the lining paper is likely to shift during transportation. Through the above cutting process, the cut lining paper can be pressed and used to maintain the tension force during transportation, and thus will not affect the progress of the lining paper unwinding and transportation, and at the same time ensure the stability during the lining paper cutting and prevent the cutting position from shifting.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-3, the present utility model provides a technical solution: an automatic pickling paper feeding and cutting device, which includes a mounting steel frame 1, and a unwind rack 2 for feeding a roll of paper is provided at the bottom end inside the mounting steel frame 1. A roll of backing paper can be placed on the unwind rack 2 to convey the backing paper and attach it to the surface of the steel strip being pickled. An upper end inside the mounting steel frame 1 is inclined with a tension guiding roller 3 for guiding and outputting the paper output by the unwind rack 2. It can change the conveying angle and direction of the conveyed backing paper, and can play a role in tension support during the conveying of the backing paper to avoid the phenomenon of wrinkles on the backing paper. A unwind paper support cutting plate 4 is inclined and provided at the corresponding bottom side of the tension guiding roller 3 and inside the mounting steel frame 1, which is beneficial for pressing and cutting the paper to be fed and cut. When the backing paper is being conveyed, it is supported by the unwind paper support cutting plate 4 on an inclined plane. At the same time, when the backing paper needs to be cut, it is pressed against the unwind paper support cutting plate 4 for pressing, so as to facilitate the further conveying of the backing paper. Embedding holes 17 are evenly provided on the surface of the unwind paper support cutting plate 4, and rubber ball members 18 are movably embedded in the embedding holes 17, which can avoid direct contact between the backing paper and the unwind paper support cutting plate 4 during conveying, resulting in large friction. The backing paper reduces friction through the rotation of the rubber ball members 18 in the embedding holes 17. A paper cutting mounting plate member 5 for installing a pneumatic paper cutting mechanical part for the unwind paper is inclined and provided at one side of the top end inside the mounting steel frame 1. The pneumatic pressing roller 6 can be installed on the outer side of the inclined downward end of the paper cutting mounting plate member 5 through a cylinder member 15. A pneumatic pressing roller 6 for pressing and assisting in cutting the unwind paper is pneumatically telescoped on one side of the paper cutting mounting plate member 5. By using a pneumatic method, the pneumatic pressing roller 6 moves to press and fix the cut end of the backing paper, avoiding the loosening of the roll of backing paper, which is not conducive to conveying. A feeding and cutting blade 7 for cutting the unwind paper is provided on one side of the mounting frame of the pneumatic pressing roller 6. After the pickling and conveying of the roll of steel strip is completed for one circle, the backing paper can be cut by the feeding and cutting blade 7 to separate the roll of steel strip from the backing paper.

[0018] On one side inside the installation steel frame 1, there is an installation seat 8 for adjusting and fixing the position and direction of the connecting frame 9. Inside the installation seat 8, there is a connecting frame 9 which can support one end of the unwind roller shaft 11 in an upward inclined manner. The connecting frame 9 is connected to one end of the unwind frame 2 through a pin shaft connecting part. On both inner sides of the V-shaped notch opened at one end of the unwind frame 2, there are positioning roller wheels 10, and between the positioning roller wheels 10, there is an unwind roller shaft 11 rotatably installed on one side inside the installation steel frame 1. The continuous paper is threaded onto the unwind roller shaft 11 to perform the unwinding and conveying of the liner paper. And the paper roll body 12 is threaded and assembled on the unwind roller shaft 11, and the liner paper can be conveyed to the surface of the pickled steel strip being wound up to play a role in protecting the surface of the steel strip after pickling. On both ends of the fixed frame of the pneumatic pressing roller 6, there are guide slide rods 13. The guide slide rods 13 can ensure the stability of the telescopic sliding of the pneumatic pressing roller 6 during the telescopic and inclined downward position movement, and prevent the problem of position deviation. And at the other end of the guide slide rod 13, there is a limit fixing block for limiting the stroke of the guide slide rod 13, which can limit the stroke of the pneumatic pressing roller 6 and avoid the phenomenon that the liner paper is torn due to the large thrust of the cylinder part 15.

[0019] On one side of the fixed frame of the pneumatic pressing roller 6, there is a tool holder 14 in an L-shaped structure, and the feeding cutting blade 7 is fixed at one end of the tool holder 14 to perform the pneumatic cutting of the liner paper. One end of the feeding cutting blade 7 is fixed on the tool holder 14 and is vertically corresponding to the pneumatic pressing roller 6, so that the feeding cutting blade 7 and the pneumatic pressing roller 6 can contact the surface of the liner paper synchronously and perform pressing and cutting synchronously. In the middle of one side of the paper cutting mounting plate member 5, there is a cylinder part 15. The cylinder part 15 is connected to an external PLC controller to control the telescopic length, telescopic speed and stroke of the cylinder part 15. One end of the piston rod of the cylinder part 15 is fixed on the bracket in the pneumatic pressing roller 6, and on both sides of the cylinder part 15, there are fixed guide blocks 16 symmetrically. The fixed guide blocks 16 are movably sleeved on the guide slide rods 13 for guiding and positioning, which can enable the feeding cutting blade 7 to accurately cut the liner paper output by the pneumatic pressing roller 6.

[0020] Specifically, during use, first, the roll of paper roll body 12 is threaded onto the setting unwind shaft rod 11 inside the installation steel frame 1 and is inclinedly supported by the unwind frame 2 for the unwind shaft rod 11. Meanwhile, the positioning roller 10 is used to fit and limit both ends of the unwind shaft rod 11. Subsequently, the backing paper is pulled out and passed through the unwind paper support cutting plate 4. Meanwhile, with the help of the tensioning guide roller 3, the conveying direction of the backing paper is changed symmetrically, and the output end of the backing paper is wound on the reel for pickling winding outside. As the steel strip is wound, the backing paper continuously outputs from the paper roll body 12. When it is necessary to unload the pickled steel strip after it is wound into a circle, at this time, the external controller controls the cylinder part 15 to push the pneumatic pressing roller 6 to move obliquely. While the pneumatic pressing roller 6 moves obliquely, the guiding slide rod 13 slides in the fixed guide block 16, which can ensure that the pneumatic pressing roller 6 remains in a fixed moving position during movement. And the tool holder 14 and the cutting blade 7 installed on the tool holder 14 move synchronously. And the pneumatic pressing roller 6 is pressed against the surface of the unwind paper support cutting plate 4 to press and position the backing paper. Moreover, the cutting blade 7 cuts the backing paper at its front end and cuts it off from the backing paper on the wound steel strip. Then, after the wound steel strip is unloaded, the backing paper is reconnected to the steel strip reel. Through the above cutting process, it can prevent the wound backing paper from falling off after being cut, making the relatively tight wound backing paper become relatively loose without tension, so that the backing paper is likely to shift during further conveyance.

[0021] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
