Technical Field

[0001] This utility model belongs to the field of high-speed papermaking equipment manufacturing, specifically relating to an easy-to-peel scraper assembly with a blowing device. Background Technology

[0002] Doctor blades are indispensable components in papermaking equipment. They are used not only to scrape off residual paper scraps from the surface of the guide rollers but also to separate paper from the paper feed roller. However, existing doctor blade assemblies have the following shortcomings when used at the paper feed roller: 1. Due to the inability or inconvenience of adjusting the overall angle and position of existing doctor blade assemblies, maintenance, repair, and replacement of the paper feed roller are easily hindered by the doctor blade device, resulting in limited operating space and inconvenience. 2. During the process of separating paper from the roller by contacting the doctor blade body with the outer surface of the rotating paper feed roller, the inertia of the paper can cause the scraped paper to adhere tightly to the doctor blade body during high-speed operation, affecting the normal feeding of the paper and the overall performance of the doctor blade device. Therefore, to solve the above problems, it is necessary to develop an easy-to-peel doctor blade assembly that is easy to adjust, has good performance, and is equipped with a blowing device. Utility Model Content

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Example: Figure 1 , Figure 2 , Figure 3As shown, an easy-to-peel scraper assembly with a blowing device includes an adjusting cylinder 1, an intermediate connecting member 2, and a scraper device 3. The adjusting cylinder 1 is vertically oriented, with a fixed base 4 hinged to its lower end and a support 5 hinged to its upper end. The intermediate connecting member 2 is square in shape, hollow inside, and fixedly mounted on the right side of the support 5. An air injection hole 21 is provided on the upper part of the front end face of the intermediate connecting member 2. A rotating shaft 22 is longitudinally fixedly mounted on the lower part of both the front end face and the lower part of the rear end face. Multiple nozzles 23 are evenly fixedly mounted on the upper part of the right side face. A mounting base 24 is rotatably sleeved on the outside of the rotating shaft 22. The scraper device 3 is vertically positioned above the nozzles 23 and fixedly connected to the outer right side wall of the intermediate connecting member 2. It includes a base plate 31 and a connecting block 32. The scraper body 33 and the base plate 31 are fixedly mounted on the upper end of the outer right side of the intermediate connector 2. The connecting block 32 is fixedly connected to the base plate 31 on one side, and a slot 34 is provided in the middle of the other side. A connecting seat 35 is fixedly mounted in the middle of the bottom surface of the slot 34. An adjusting airbag a36 is fixedly mounted at the upper end of the bottom surface of the slot, and an adjusting airbag b37 is fixedly mounted at the lower end of the bottom surface of the slot. The scraper body 33 is located outside the connecting block 32. One end of the scraper body 33 is in contact with the outer surface of the paper guide roller, and the inner side of the other end is fixedly connected to the adjusting airbag a36 and the adjusting airbag b37. A locking block 38 is fixedly mounted in the middle of the fixed connection between the inner side of the scraper body 33 and the adjusting airbag a36 and the adjusting airbag b37. The locking block 38 is hinged to the connecting seat 35.

[0018] The nozzle 23 is L-shaped, and both the nozzle 23 and the air injection hole 21 are connected to the intermediate connecting piece 2; a mounting plate 25 is fixedly installed below the mounting base 24, and the mounting plate 25 is fixedly connected to the paper machine frame by bolts; both the regulating air bag a36 and the regulating air bag b37 are externally connected to regulating air pumps; the fixed base 4 is fixedly connected to the paper machine frame by bolts.

[0019] Before using this utility model, the position of the scraper device 3 needs to be adjusted. The specific adjustment operation is as follows: By controlling the adjustment cylinder 1 to retract, at this time, by utilizing the hinges between the two ends of the adjustment cylinder 1 and the fixed base 4 and the support 5 respectively, the fixed connection between the support 5 and the intermediate connecting piece 2, the fixed connection between the intermediate connecting piece 2 and the rotating shaft 22, and the rotational sleeve between the rotating shaft 22 and the mounting base 24, the intermediate connecting piece 2 can be rotated counterclockwise around the rotating shaft 22 by the support 5 while the adjustment cylinder 1 retracts. Then, by moving the intermediate connecting piece 2, the scraper device 3 fixedly installed on the upper right side of the intermediate connecting piece 2 can be moved, thereby realizing the overall position adjustment of the scraper device 3. This utility model adopts this structure, which can avoid the problem of small operating space and inconvenience in operation due to being too close to the scraper device 2 during the disassembly or installation of the paper guide roller.

[0020] After adjusting the position of the scraper device 3, in use, firstly, by adjusting the air pump to control the airbag a36 to vent and the airbag b37 to inflate, the scraper body 33 is driven to rotate counterclockwise around the airbag 38 by adjusting the airbag a36 to vent and contract and the airbag b37 to inflate and expand. This completes the contact between the outer end of the scraper body 33 and the outer surface of the paper guide roller, and simultaneously switches the scraper body 33 from the standby position to the working position. Thus, by using the contact between the scraper body 33 and the outer surface of the high-speed rotating paper guide roller, the paper on the outer surface of the paper guide roller can be scraped off. At the same time, the air injection hole 2... 1. The hollow intermediate connector 2 and nozzle 23 are designed to allow an external fan to supply air into the intermediate connector 2 through the air injection hole 21, while the L-shaped nozzle 23 can also spray the air into the intermediate connector 2 upwards. Under the action of this air force, the paper is blown away, thus separating the paper from the doctor blade body 33. This structure avoids the paper sticking to the doctor blade body 33 after being scraped off the outer surface of the paper guide roller, which would affect the overall performance of the doctor blade device 3. At the same time, the air force can blow the paper away, thereby changing the falling direction of the paper and achieving precise paper feeding. In summary, this invention has the advantages of convenient adjustment and good performance.
