Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper processing, in particular to a deburring tool for corrugated board. Background Art

[0002] Since corrugated paper is made of pulp containing plant fibers, some corrugated paper will produce burrs at the edges after cutting, which will affect subsequent processing operations. In the prior art, workers usually use a utility knife to scrape off the burrs on the cut edges of corrugated paper. In the process of deburring, there are defects of poor effect and low work efficiency, which need to be improved. Chinese patent document CN213944020U discloses a deburring device for the side of corrugated paper, but in use, the distance between two clamping plates needs to be adjusted to adapt to different corrugated papers, and continuous adjustment is required for different corrugated papers. Moreover, in use, it can only remove burrs unidirectionally and cannot scrape repeatedly to remove burrs, so the deburring effect is not good; on this basis, patent document CN118305676A discloses a device for removing burrs from corrugated board, which is essentially a superposition and rotation of multiple blades to pick off burrs. Such blades are very easy to damage the edges of corrugated paper during operation, and even make them serrated, which is very difficult to control during operation and has a large operation difficulty.

[0003] Now a deburring tool for corrugated board is provided, which can be applicable to corrugated papers of different thicknesses, can scrape the burrs on the two side edges of corrugated paper repeatedly to achieve the purpose of removal, and has simple operation and is easy to control. Summary of the Utility Model

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a deburring tool for corrugated board, which effectively solves the problems of poor deburring effect and large operation difficulty of the prior art in deburring corrugated paper.

[0005] The technical solution it adopts is that it includes two long plates symmetrically arranged front and back. The two long plates are placed horizontally, and there is a gap between the two long plates. There are two working wheels in the gap. A lower groove is provided on the outer circumferential surface of the working wheel, and the cross-section of the lower groove is V-shaped; the central axis of the working wheel is hinged on the long plate. There is a movable plate parallel to each long plate above. The lower end of the movable plate is hinged to the upper end of the long plate. A rubber layer is fixed on the side of the movable plate close to the working wheel; when the two movable plates are clamped towards the middle, the working wheel can be fixed.

[0006] Further, a handle is fixed to the upper end of the movable plate.

[0007] Further, the lower end of the movable plate and the upper end of the long plate are hinged through a torsion spring.

[0008] Further, the working wheel is a grinding wheel.

[0009] Further, abrasive cloth is pasted on the outer circumferential surface of the working wheel.

[0010] Further, the working wheel is a pulley, and the two working wheels are wound with a belt. Abrasive paper is pasted on the outer surface of the belt.

[0011] The utility model has a clever structure, can be applied to corrugated paper with different thicknesses, can repeatedly scrape the burrs on the two side edges of the corrugated paper to achieve the purpose of removal, is simple to operate and easy to control.

[0015] The following further elaborates the detailed description of the preferred embodiments of the utility model with reference to the drawings.

[0016] Given by Figures 1 to 3 The utility model includes two long strip plates 1 that are symmetrically arranged front and back. The two long strip plates 1 are horizontally placed with a gap therebetween. There are two working wheels 2 within the gap. The outer circumferential surface of the working wheel 2 is provided with a lower groove, and the cross-section of the lower groove is V-shaped. The central axis of the working wheel 2 is hinged to the long strip plate 1. There is a movable plate 3 parallel to each long strip plate 1 above. The lower end of the movable plate 3 is hinged to the upper end of the long strip plate 1. A rubber layer 4 is fixed on the side of the movable plate 3 close to the working wheel 2. When the two movable plates 3 are clamped towards the middle, the working wheel 2 can be fixed.

[0017] For convenient use, a handle 5 is fixed to the upper end of the movable plate 3.

[0018] For convenient use, the lower end of the movable plate 3 and the upper end of the long strip plate 1 are hinged via a torsion spring.

[0019] The working wheel 2 is a grinding wheel.

[0020] To reduce the wear of the working wheel 2, abrasive cloth is pasted on the outer circumferential surface of the working wheel 2.

[0021] To increase the contact area with the corrugated paper, the working wheel 2 is a pulley, and the two working wheels 2 are wound with a belt. Abrasive paper is pasted on the outer surface of the belt.

[0022] It is worth noting that there are many embodiments of the working wheel 2 of this solution. For the convenience of explanation, the specific use process is described in detail by taking the grinding wheel as an example. Since the knives in modern technology are already very sharp, the burrs on the edge of the corrugated paper are mostly small burrs, which can be basically removed by gently scraping them repeatedly a few times. Grinding wheels, emery cloths, and sandpaper can all achieve this purpose.

[0023] When in use, pinch the handle 5 to bring the two movable plates 3 closer to the middle and clamp the working wheel 2. At this time, the working wheel 2 cannot rotate. Then place the edge of the corrugated paper in the lower groove on the outer surface of the working wheel 2, press it with a little force and rub it repeatedly to remove the small burrs on the edge of the corrugated paper. After using it for a period of time, the working wheel 2 will be partially worn. At this time, the working part of the working wheel 2 needs to be adjusted. Specifically, the two movable plates 3 are pried apart to both sides, and the rubber layer 4 is completely separated from the working wheel 2. At this time, the working wheel 2 can rotate freely. After adjustment, let go, and the movable plate 3 will move closer to the working wheel 2 again under the action of the torsion spring, and the working wheel 2 will be fixed and not rotated.

[0024] The utility model has an ingenious structure, can be suitable for corrugated papers of different thicknesses, can repeatedly scrape the burrs on the two side edges of the corrugated paper to achieve the purpose of removing the burrs, and is simple to operate and easy to control.
