detailed description

Referring to Fig. 1, the chamfering and cutting mechanism for plate splicing includes a frame 1 and a chamfering and cutting assembly installed on the frame 1. Above, the movable tool rest 3 moves along the edge of the plate, and the cutting tool 2 cuts and chamfers the edge of the plate. Using the cutting tool 2 to realize the chamfer cutting through the movable tool holder 3 can ensure a smooth cut and high machining accuracy, a large amount of processing dust will not be generated during the machining process, and the cutting tool 2 is not easy to wear. In addition, the moving tool rest 3 has a fast moving speed, and can quickly realize fast cutting and chamfering of two edges of the plate, thereby improving the degree of automatic production and production efficiency.

In order to realize the splicing of infinite length, it is necessary to continuously splice the plates in the way of connecting the end to the end. For this reason, each plate needs to be chamfered and cut at the edge of the spliced head and tail. Therefore, the chamfering and cutting components are divided into two groups, respectively Set on both sides of the plate, one set of cutting tools 2 chamfers the upper surface of the edge of the plate, and the other set of cutting tools 2 chamfers the lower surface of the edge of the plate. The two groups of chamfering and cutting components work synchronously, that is, they can complete cutting and chamfering on the upper surface and the lower surface respectively. The upper surface chamfer of the front panel and the lower surface chamfer of the rear panel just match, and the splicing and fixing can be completed after the glue is applied and pressed, and the panels are spliced end to end in turn to achieve infinite length.

Due to the different materials and cutting parts of the board, such as the board obtained by processing wood close to the skin, the sheet-like board may have a large number of wrinkles as a whole, and such a sheet-like board will not be able to complete cutting chamfering and subsequent splicing. But in order to improve the utilization rate of wood to save resources, the utility model is provided with the clamping mechanism that is used for clamping plate edge before cutting tool 2. Wherein the clamping mechanism is composed of a translational clamping block 4 and a driving mechanism, and the driving mechanism drives the clamping block 4 to translate up and down. When the sheet material enters the working range of the chamfering cutting assembly, the driving mechanism drives the clamping block 4 to tightly clamp the edge of the sheet material to be processed, and under the action of the upper and lower planes of the clamping block 4 The edge of the sheet material is leveled, and at the same time, it can ensure that the edge of the sheet material is firmly fixed during processing, preventing movement from affecting the processing accuracy.

In order to make the movement of the movable tool rest 3 complete the chamfering and cutting work, the frame 1 is provided with a sliding guide rail 5, and the movable tool rest 3 is installed on the sliding guide rail 5 for translation. In order to complete the working needs of the movable knife rest 3 for feeding and withdrawing the knife, a slide plate 6 is installed on the sliding guide rail 5, and the movable knife rest 3 is installed on the slide plate 6 through a horizontal translation mechanism 7, and the horizontal translation mechanism 7 moves in the same direction as the sliding guide rail 5. vertical. When working, when the sheet-like plate enters the processing station, the edge of the sheet-like plate is first firmly clamped and leveled by the clamping mechanism, and then the horizontal translation mechanism 7 drives the movable knife holder 3 to realize the knife feeding, and then the slide plate 6. Under the action of the driving mechanism, move along the sliding guide rail 5 to complete the chamfering of the edge, and then the horizontal translation mechanism 7 drives the movable tool holder 3 to realize the tool retraction. The clamping mechanism separates and releases the sheet material, and the chamfering is completed. The final sheet-like panels are sent to the process of assembling and lengthening.

Since different plates have different thickness requirements, in order to meet the cutting needs of plates of different thicknesses and improve machining accuracy, a cascaded vertical fine-tuning mechanism 8 and a horizontal fine-tuning mechanism 9 are installed in the movable tool holder 3, and the cutting tool 2 is installed On the cascaded vertical fine-tuning mechanism 8 and horizontal fine-tuning mechanism 9. By adjusting the horizontal fine-tuning mechanism 9 and the vertical fine-tuning mechanism 8 during debugging, the cutting tool 2 can meet the cutting needs of plates with different specifications.

The specifications of plywood are generally fixed, so the size of the existing sheet-like boards is also relatively standardized, so the distance between the two sets of chamfering and cutting components is also relatively fixed. However, in order to enable this mechanism to process some non-standard size sheet materials, one group of chamfering cutting assemblies can translate relative to the other group of chamfering cutting assemblies, that is, the distance between the two groups of chamfering cutting assemblies can be adjusted. Specifically, it is also the structure of the screw rod and the guide rail used. A set of chamfering cutting components is installed on the guide rail, and the screw rod drives it to produce translation, thereby realizing the adjustment of the spacing.
