Description

Technical Field

[0001] This utility model relates to the field of waste scraper technology, specifically a waste scraper for paper production. Background Technology

[0002] In the papermaking process, flexographic printing machines are an essential piece of machinery. As the paper moves on the flexographic printing machine, the rollers rotate. However, during the rotation, waste material easily adheres to the rollers. If there is too much waste material, it will cause the rollers to come into contact with the subsequent paper and press the waste material onto the paper. Therefore, the waste material on the rollers is scraped off by a doctor blade.

[0003] The existing doctor blades need to be replaced after they are damaged. Only after the replacement is completed can the doctor blades be put back into use on the roller. The replacement time of the existing doctor blades is long, which increases the downtime of paper production equipment and reduces the paper production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a waste adhesive scraper for paper production, in order to solve the problem mentioned in the background art that the scraper replacement time is long, which increases the downtime of paper production equipment and reduces the paper production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a scraper for adhering waste in paper production, comprising a bearing seat, a roller rotatably connected to the surface of the bearing seat, a blade changing mechanism provided on the surface of the bearing seat, the blade changing mechanism comprising a support plate, a rotating rod rotatably connected to the surface of the support plate and the bearing seat, an adjusting rod fixedly connected to the surface of the rotating rod, a connecting rod fixedly connected to the surface of the adjusting rod, a second spring fixedly connected inside the connecting rod, an mounting rod fixedly connected to the surface of the second spring, the mounting rod slidably connected to the surface of the connecting rod, a scraper body mounted on the surface of the mounting rod, a first spring fixedly connected to the inner surface of the rotating rod, a movable rod fixedly connected to the surface of the first spring, the movable rod slidably connected to the surface of the rotating rod, a limiting plate fixedly connected to the surface of the movable rod, and a positioning rod fixedly connected to the surface of the support plate, the positioning rod being perforated and connected to the surface of the limiting plate.

A third spring is fixedly connected to the surface of the mounting rod, and a limiting rod is fixedly connected to the surface of the third spring. The limiting rod is slidably connected to the surface of the mounting rod.

[0007] Preferably, the adjusting rod rotates on the surface of the support plate via a rotating rod, and the scraper body is provided in two sets. The adjusting rod drives the two sets of scraper bodies to rotate on the support plate via a connecting rod and a mounting rod.

[0008] Preferably, a guide groove is formed on the surface of the connecting rod, the mounting rod slides on the guide groove of the connecting rod, multiple sets of the second spring are provided, and the elastic force of the second spring acts on the scraper body through the mounting rod.

[0009] Preferably, a rectangular groove is formed on the surface of the rotating rod, and the movable rod slides on the rectangular groove of the rotating rod in a rectangular shape.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This waste scraper uses a rotating rod to rotate an adjusting rod on a support plate. The adjusting rod, through a connecting rod and a mounting rod, drives the scraper body to rotate, thereby exchanging the positions of the two sets of scraper bodies. The elastic force of the first spring acts on the limiting plate through a movable rod, causing the positioning rod to be connected to the limiting hole of the limiting plate. The positioning rod, through the limiting plate and the movable rod, restricts the rotation of the rotating rod, thus limiting the position of the scraper body on the adjusting rod. This enables rapid switching of the scraper body, thereby reducing downtime of paper production equipment and ensuring paper production efficiency.

[0014] 2. This waste scraper uses a locking rod to engage with the slot on the support rod, thereby positioning the scraper body on the mounting rod. The third spring, through its elasticity, causes the limiting rod to slide towards the limiting block in the guide hole of the mounting rod, allowing the limiting rod to pass through the limiting hole of the limiting block. The limiting rod, through the limiting block, restricts the scraper body on the surface of the mounting rod, thus enabling the installation of the scraper body. It also facilitates the disassembly of the scraper body, making it easier for workers to maintain the scraper body and reducing the maintenance time for workers. Attached Figure Description

The adjusting rod 22 drives the doctor blade body 25 to rotate via the connecting rod 23 and the mounting rod 24, thereby realizing the exchange of positions between the two sets of doctor blade bodies 25. The elastic force of the first spring 26 acts on the limiting plate 28 through the movable rod 27, so that the positioning rod 29 is connected to the limiting hole of the limiting plate 28. The positioning rod 29 restricts the rotation of the rotating rod 21 through the limiting plate 28 and the movable rod 27, thereby restricting the position of the doctor blade body 25 on the adjusting rod 22, realizing the rapid switching of the doctor blade body 25, thereby reducing the downtime of the paper production equipment and ensuring the paper production efficiency.

[0033] The locking rod 31 is engaged with the slot of the support rod 3 to position the scraper body 25 on the mounting rod 24.
