Description

Technical Field

[0001] The utility model relates to an improved plate processing device, in particular to a plate dovetail groove processing device. Background Art

[0002] Wood board is a widely used building material. Its unique wood texture can be used as a decorative structure for building surfaces such as floors or walls. Boards are usually laid flat, so they need to be spliced and fixed. Usually, the boards are mainly connected to the frame through wooden nails. The connection between the boards is weak, and problems such as uneven gaps may occur. There are also problems such as abnormal noises during use. After grooving the boards, the boards can be connected through the groove shape, the connection is tight, and the gap between the splices is uniform. Therefore, a device for processing and splicing groove structures for boards is needed. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a dovetail groove processing device for a plate.

[0004] The technical solution adopted by the present invention to solve the above problems is: the side of the plate is processed into a dovetail groove, which is a relative matching splicing structure, which is a notch and a tenon respectively, and the notch and the tenon are respectively formed on the edges of the opposite sides of the plate, and the processing device is provided with a notching device and a tenoning device for forming the notch and the tenon respectively, and the processing device includes a processing table and a positioning backrest, and the notching device and the tenoning device are arranged above the working surface of the processing table, and the cutting parts of the notching device and the tenoning device are arranged beyond the surface of the positioning backrest, and the side of the plate is arranged against the surface of the positioning backrest and the excess material is cut off in the notching device and the tenoning device. The dovetail groove is the main groove structure for forming a wedge-shaped connection. The groove is wider than the notch, and the edges at both ends of the board are processed into a notch and a tenon respectively to form a matching connection. The dovetail groove has a large connection surface and good anti-slip performance. The structure of the dovetail groove required is set separately. The positioning basis of the wooden board is the table top of the processing table and the positioning backrest. The right-angle structure is used to provide a reference position for the processing of the wooden board. The grooving device and the tenoning device are set separately, and the processing accuracy is adjustable.

[0005] Furthermore, the slotting device includes a slotting knife, a drive motor, an angle adjustment disk, and a displacement adjustment frame. The slotting knife is composed of two blades with intersecting cutting surfaces. The slotting knife is controlled by the drive motor and forms an inclined cutting angle through the angle adjustment disk. The inclined cutting angles of the two blades form a dovetail notch structure. The drive motor is also connected to the displacement adjustment frame, which controls the distance the slotting knife is exposed on the surface of the positioning backing. The slotting device needs to open a slot structure that is wide inside and narrow outside. This is achieved by using two slotting knives that intersect at a spatial angle. The slotting knives each open half of the slot structure, and when combined, form a complete slot. The displacement adjustment frame can adjust the slot depth to meet the requirements of different wooden boards.

[0006] Furthermore, the slotting knives are arranged sequentially in the slotting direction, and the outer edges of the slotting knives are cutting edges, the cross-section of which corresponds to the cross-section of the dovetail slot. Utilizing the cross-sectional shape of the cutting edges, a centering bump can be cut at the bottom of the slot, thereby forming a centering position based on the existing dovetail slot and reducing gaps caused by machining errors.

[0007] Furthermore, the mortising device includes a mortising knife, a center knife, a drive motor, and a displacement adjustment frame. The mortising knife and the center knife are both connected to the drive motor. The mortising knife is arranged in two parallel axial directions, with a tenon forming space between the two mortising knives. The cutting edge of the center knife corresponds to the middle of the tenon. The center knife is arranged axially vertically. The mortising knife and the center knife are both connected to the displacement adjustment frame via the drive motor. The mortising knife can be synchronously controlled on both sides of the tenon. The center knife arranged in the middle is to cooperate with the center protrusion to enhance center positioning.

[0008] Furthermore, the outer edge of the mortising knife is formed with a cutting edge, and the cross section of the cutting edge is set corresponding to the free cross section on one side of the tenon. The cutting edge of the mortising knife needs to be kept opposite on both sides to maintain a balanced feed amount.

[0009] Compared with the existing technology, the utility model has the following advantages and effects: the design is a device for processing dovetail grooves of wooden boards, which can relatively form grooves and tenons, effectively improve production efficiency, and the processing method is convenient. It can be directly aligned with the reference surface for push processing, which can improve the tightness of the connection of the boards and maintain the stability of the gap between the boards.
