Description

Technical Field

[0001] The utility model relates to the technology of automatic processing equipment field, in particular to a positioning and adjusting tool for a positioning back plate of a compact edge banding machine. Background Art

[0002] An edge banding machine is a commonly used woodworking machine that can realize mechanized edge banding operation. First, it heats and melts the hot melt adhesive, then applies it to the edge of the board, and finally fixes the edge band to the edge of the board. In order to keep the board positioned and enter the edge banding machine neatly for automatic edge banding, a feeding guiding mechanism is arranged at the feeding end of the edge banding machine. Before the board is automatically conveyed into the edge banding machine for edge banding, the mechanism abuts against the edge of the board through the side of the feeding guiding back plate to guide the moving board and correct the straightness of the board edge, ensuring that the edge of the board can enter the edge banding machine neatly and accurately for edge banding processing.

[0003] When the edge banding machine is performing edge banding on the board, it positions the edge banding board through the positioning back plate of the feeding guiding mechanism and conveys the board through the conveying chain plate to realize functions such as edge banding and trimming of the board. Therefore, the parallelism between the conveying chain plate and the positioning back plate directly affects the conveying accuracy of the board, and further affects the edge banding quality. The conveying chain plate of this type of edge banding machine is positioned through the positioning groove on the guide rail and conveyed through the chain. There are high positioning requirements among the conveying chain plate, the positioning back plate and the guide rail. The processing error of the guide rail will cause inaccurate positioning. Moreover, the position adjustment of its positioning back plate relies on manual adjustment by loosening the bolts and then using hands. This manual adjustment method is time-consuming and laborious, and it is difficult to ensure the position accuracy of the positioning back plate, resulting in difficulty in ensuring the processing accuracy of the board, and there is a problem that the positioning back plate is difficult to adjust.

[0004] Therefore, it is necessary to research a new technology to solve the above problems. Content of the Utility Model

[0005] In view of this, aiming at the deficiencies existing in the prior art, the main purpose of the utility model is to provide a positioning and adjusting tool for a positioning back plate of a compact edge banding machine, which can eliminate inaccurate positioning caused by the processing error of the guide rail, and can make the positioning adjustment of the positioning back plate more convenient, more efficient and more accurate.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

The diameter of the relief hole is smaller than the diameter of the steel ball. The front end of the compression spring extends into the positioning hole. The steel ball is located in the positioning hole, and the other end of the steel ball extends out of the relief hole.

[0013] As a preferred solution, the front side surface of the support plate is recessed backward with an assembly groove. The assembly groove penetrates to the lower surface of the support plate. The positioning block is located in the assembly groove.

[0014] As a preferred solution, the rear side surface of the support plate is recessed forward with a mounting hole.

The positioning block 60 is located in the assembly groove 22. The rear inner side wall of the assembly groove 22 is provided with a first connection hole 25. The positioning block 60 is provided with a second connection hole 63. The first connection hole 25 and the second connection hole 63 are fixedly connected by screws. The rear side surface of the support plate 20 is recessed forward with a mounting hole 23. The front end of the mounting hole 23 is provided with an assembly hole 24 inside the support plate 20.

One end of the steel ball abuts against the compression spring, and the other end is exposed on the front side surface of the support plate. The other end of the steel ball is used to abut against the front inner side surface of the positioning groove on the guide rail of the edge banding machine. Thus, when it is applied to the edge banding machine, the support plate is stuck in the positioning groove of the guide rail of the edge banding machine, the tooling reference plate simulates the board, and the tooling reference plate reference surface of the tooling reference plate simulates the detection surface. The steel ball can be stressed on the front inner side surface of the positioning groove on the guide rail, so that the support plate reference surface of the support plate is closely attached to the rear inner side surface of the positioning groove on the guide rail, eliminating the inaccurate positioning caused by the machining error of the guide rail. The tooling reference plate reference surface can be used to calibrate and adjust the reference surface of the positioning stop of the edge banding machine, making the positioning adjustment of the positioning stop more convenient, efficient, and accurate. Moreover, compared with the traditional calibration methods such as driving the board, power-on conveying, and dial indicator measurement, it saves time and effort, greatly improving the convenience and efficiency.
