[0016] In order to make the patent purposes, technical schemes and advantages of the present application clearer, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0017] In order to illustrate the technical scheme of the present application, the following specific examples are used to illustrate the present application.

[0018] In order to facilitate the description, only parts related to the embodiments of the present application are shown.

[0019] In combination with Figures 1-3As shown, the wood slotting device comprises a slotting box 1, a slotting opening 2 is formed on the top of the slotting box, a slotting mechanism is arranged in the slotting box 1 at the slotting opening 2, a push-in assembly, a pair of guide plates 3 and a pre-tightening assembly are sequentially arranged in the slotting box 1 from front to back towards the slotting opening 2, a limiting assembly is arranged on the slotting box 1 above the two guide plates 3, the slotting mechanism comprises a pair of fixed seats 4 installed on the slotting box 1, a rotating shaft 5 is arranged between the fixed seats 4, a slotting shaft 6 is arranged on the rotating shaft 5, a spiral slotting cutter 7 is arranged on the slotting shaft 6, a plurality of cutter heads 8 are uniformly arranged on the slotting cutter 7 along the spiral direction, a driven wheel 9 is arranged on the slotting shaft 6, and a slotting motor (hidden in the figure) is arranged in the slotting box 1, a driving shaft of the slotting motor is provided with a driving wheel, and a belt 11 is arranged between the driving wheel and the driven wheel 9.

[0020] In the above structure, the guide plate and the pre-tightening assembly constitute a discharging area interval, and the discharging area interval is used for placing the wood. When the wood is slotted by using the device, the wood is first placed in the discharging area interval, then the push-in assembly pushes the wood towards the slotting mechanism, and when the wood is pushed into the slotting position, the slotting mechanism starts to slot the wood. During the slotting process of the wood, the push-in assembly continues to slowly push the wood, and the slotting depth of the wood is controlled by the push-in assembly.

[0021] When the slotting mechanism starts to work, the slotting motor drives the driving wheel to rotate, and under the linkage of the belt, the driven wheel drives the slotting shaft to rotate. When the slotting shaft rotates, the slotting cutter and the cutter head also rotate and slot the wood.

[0022] During the rotation of the slotting cutter, the cutter head cuts along the width direction of the wood to form the required slot. Since the slotting cutter is spiral, each cutter head is in circular motion during rotation, and the projections of adjacent two cutter heads in the axial direction partially overlap, so that a groove with a certain width can be formed on the edge of the wood. After the wood is slotted, the push-in assembly is reset and no longer pushes the wood, and finally the worker takes away the wood.

[0023] In the structure, the push-in assembly comprises a top seat 23 installed on the slotting box 1, the top seat 23 is provided with an electric push cylinder 24, a connecting seat 25 is arranged on the driving shaft of the electric push cylinder 24, and a push-in plate 26 is arranged on the connecting seat 25. When the wood is pushed to the slotting mechanism by using the push-in assembly, the electric push cylinder drives the connecting seat to move backward, and the push-in plate pushes the wood to move backward.

[0024] As a specific structure, as shown in Figures 1-2The pre-tightening assembly comprises a pair of pre-tightening seats 12 installed on both sides of the slotting opening 2, a pair of pre-tightening rods 13 slidingly arranged on the pre-tightening seats 12, a pair of short plates 14 arranged between the pre-tightening rods 13, and a pre-tightening spring 15 arranged between the lower pre-tightening rod 13 and the pre-tightening seat 12.

[0025] In the structure, the pre-tightening assembly comprises a pair of pre-tightening seats, a pair of pre-tightening rods slidingly arranged on the pre-tightening seats, and short plates arranged at both ends of the pre-tightening rods. In the actual slotting process, when the pushing assembly pushes the wood board to the slotting position for slotting, the wood board will push the two front short plates to move backward, and then the two pre-tightening rods will slide backward in the pre-tightening seats. Under the pushing of the wood board, the spring is gradually compressed, and under the pre-tightening action of the spring, the wood board is clamped by the two short plates and the pushing plate during the slotting process, thereby improving the slotting quality of the wood board.

[0026] In addition, after the wood board is completed slotting, the pushing assembly is reset, the pushing plate no longer pushes the wood board, the pre-tightening spring restores the deformation, and the two front short plates push the wood board forward by a small distance, so that the two ends of the wood board are away from the limiting assembly by a small distance, and the work personnel can take away the wood board.

[0027] In the device, Figure 1 The limiting assembly comprises a pair of limiting screws 16 installed on both sides of the slotting box 1, respectively, a limiting spring 17 arranged on each limiting screw 16, and a limiting plate 18 inserted into the same pair of limiting screws 16, and a limiting nut 19 screwed into the upper part of the limiting screw 16.

[0028] In the structure, the limiting plate and the guide-in plate on the same side constitute a limiting interval. When the wood board is placed in the feeding interval according to the requirements, the pushing plate pushes the wood board to move backward, and in this process, first, the left and right ends of the wood board will enter the limiting interval on the same side, i.e., the two limiting plates are located above the two ends of the wood board. Since the front end of the limiting plate is curved upward and forward, the wood board can smoothly enter the limiting interval. The limiting plate is used to limit the wood board upward and downward, thereby further improving the slotting quality of the wood board. In actual situations, the height of the limiting plate can be adjusted by screwing the limiting nut, so as to adapt to wood boards of different thicknesses.

[0029] Further, as a preferred structure, Figures 2-3 The slotting box 1 is provided with a top cover 20 corresponding to the slotting opening 2, the top cover 20 is provided with a pull handle 21, and the two sides of the top cover 20 are provided with avoiding breaks 22.

[0030] In the embodiment, when a series of work such as maintenance and repair of the slotting mechanism is needed, the staff can rotate the top cover by means of the pull handle, and the top cover is provided with a pair of avoiding breaks which play a role of avoiding the wood board.

[0031] The above merely describes the preferred embodiment of the present application, and is not intended to limit the present application, and any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
