[0023] Embodiment 1

[0024] like Figure 1 and Figure 2As shown together, a device for unwinding edge banding strips includes two vertically spaced fixed plates 1, a plurality of rotatable rollers 2 are provided between the two fixed plates 1, and the plurality of rollers 2 are located on the arc of the same semicircle. The radius of the arc is not less than the radius of the edge banding strip roll 11. The two fixed plates 1 and the plurality of rollers 2 together form a placement chamber 3 for placing the edge banding strips. A U-shaped groove 7 with an upper end opening is provided in the middle of the fixed plate 1, and the plurality of rollers 2 are all arranged on the circumferential side of the U-shaped groove 7. In this embodiment, thirteen rollers 2 are taken as an example, and the number of rollers 2 can be increased or decreased as required in actual application.

[0025] like Figure 1 and Figure 2 As shown together, a rotatable guide roller 4 is further provided between the two fixed plates 1, the guide roller 4 is located at one end of the fixed plate 1, and the height of the guide roller 4 is higher than the height of the supporting roller 2. In this embodiment, preferably, the number of guide rollers 4 is two, one of which is located below the other guide roller 4; the uppermost end of the guide roller 4 located below is higher than the lowermost end of the guide roller 4 located above.

[0026] like Figure 1 and Figure 2 As shown together, a plurality of fixing blocks 5 are fixed between the two fixing plates 1, and fixing holes 6 are provided at positions corresponding to the fixing blocks 5 on the two fixing plates 1, and the two fixing plates 1 are fixedly connected by the fixing blocks 5 and fasteners. The plurality of fixing blocks 5 are arranged at intervals around the placement chamber 3.

[0027] In this embodiment, preferably, the fixing blocks 5 are cylindrical and there are three of them. Of course, they can also be block-shaped. Two of the three fixing blocks are located at the two ends of the upper part of the fixing plate 1, and the third is located below the middle part of the fixing plate 1. The fasteners are bolts, nuts and washers, and the bolts pass through the fixing blocks 5 and the fixing holes 6.

[0028] When the edge strip unwinding device of the present invention is used, the operator can directly place the edge strip roll 11 in the placement chamber 3 when installing the edge strip roll 11, and pull the end of the edge strip 12 in the edge strip roll 11 from the lower side of the upper guide roller 4 and from the upper side of the lower guide roller 4 to the next process. When the edge strip roll 11 is used up and the edge strip roll 11 is replaced, the operator can directly quickly and conveniently take out the remaining roll core and place the new edge strip roll 11 in the placement chamber 3, which is convenient for installation.

[0029] Embodiment 2

[0030] like Figure 3 and Figure 4As shown together, the edge banding unwinding device of this embodiment is different from that of the first embodiment in that the number of rollers 2 in this embodiment is thirteen, and the thirteen rollers 2 are evenly distributed on the arc of the same semicircle. Mounting holes 8 are provided at the positions corresponding to the rollers 2 on the two fixed plates 1. The rollers 2 include a shaft and a roller rotatably mounted on the shaft. Both ends of the shaft are provided with mounting portions 9 that are adapted to the outer dimensions of the mounting holes 8. The outer diameter of the mounting portion 9 is smaller than the outer diameter of the shaft. The two mounting portions 9 are respectively mounted in their corresponding mounting holes 8. A compression spring 10 is mounted on one of the mounting portions 9, one end of the compression spring 10 abuts on the fixed plate 1, and the other end abuts on the end of the shaft. The outer diameter of the compression spring 10 is smaller than the inner diameter of the roller in the roller 2. When the roller 2 rotates, it will not be restricted or affected by the compression spring 10. The mounting portion 9 at one end of the roller 2 is mounted with a compression spring 10, and the mounting portion 9 at the other end of the adjacent roller 2 is mounted with a compression spring 10. That is, the compression springs 10 on all the rollers 2 are spaced apart at one end and the other end of the roller 2, so that both ends of the edge banding strip roll can be effectively supported. In this embodiment, preferably, both fixing plates 1 are provided with handles to facilitate the adjustment of the distance between the two fixing plates 1.

[0031] When the edge banding unwinding device in this embodiment is used, it is different from the first embodiment in that: in this embodiment, by changing the outer dimensions of the fixed block 5, the distance between the two fixed plates 1 can be changed, and it is used for unwinding edge bandings of different widths. When the distance between the two fixed plates 1 changes, the roller 2 can be moved closer to one of the fixed plates through the compression spring 10 at one end of the roller 2. Because the compression springs 10 on all the rollers 2 are distributed at intervals at one end and the other end of the roller 2, both ends of the edge banding roll can be effectively supported, thereby increasing the adaptability of the edge banding unwinding device to edge bandings of different widths.

[0032] In the prior art, the edge banding strips used for plate edge wrapping have many specifications, and the widths of the common specifications are 16mm, 22mm, and 25mm. The roller length of the roller 2 is selected to be 16mm. When the edge banding strips with a width of 22mm or 25mm need to be unwound, it is only necessary to adjust the distance between the two fixing plates 1 to meet the unwinding requirements.

[0033] In summary, the edge banding strip unwinding device of the present invention can facilitate the rapid installation and disassembly of the edge banding strip roll, and has the advantages of simple structure, easy operation, and convenient use.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
