[0002] Although the world has developed and produced a variety of new building materials, wood has unique and excellent properties. Wood veneers give people a special and beautiful look that other decorative materials cannot match. Therefore, wood has always maintained an important position in construction projects, especially in the field of decoration. In the process of wood processing, wood needs to be made into boards or columns, and the length of the wood needs to be screened so that it can be bundled and stored in the same size according to specifications. Summary of the invention

[0007] As a further optimization of the technical solution, the power mechanism described in a device for selecting the length of wood of the present invention includes a sliding member, a toothed shaft, a motor, a sliding member, a motor, and a bidirectional threaded rod. The motor is fixedly installed in a groove provided on a mounting frame, and a bidirectional threaded rod is fixedly installed on the output end of the motor. The bidirectional threaded rod is rotatably installed in a groove provided on the mounting frame. The sliding member is threadedly connected to the bidirectional threaded rod, and the sliding member is slidably installed in the groove provided on the mounting frame. A toothed shaft is rotatably installed in the groove of the sliding member, and the toothed shaft is fixedly installed on the output end of the motor, and the motor is fixedly installed in the groove provided on the sliding member. The sliding member is slidably installed in the groove provided on the mounting frame, and the sliding member is threadedly connected to another bidirectional threaded rod.

[0008] As a further optimization of the technical solution, the length adjustment mechanism described in a wood length selection device of the present invention includes a positioning member, an external toothed slide, monitoring device one, monitoring device two, and a strip connecting member.

[0009] As a further optimization of the technical solution, the transmission mechanism described in a device for selecting the length of wood of the present invention includes a sliding circular shaft, a square shell, a rolling short column, a pressure plate, and an arc spring. The sliding circular shaft is slidably installed in a groove set on a mounting frame, and the sliding circular shaft is threadedly connected to two bidirectional threaded rods. A pressure plate is fixedly installed on the square shell, and the pressure plate is slidably installed in a groove set on the sliding circular shaft.

[0010] The beneficial effects of the wood length selection device of the present invention are:

[0011] 1. Place the board or columnar wood on the conveying equipment and convey it forward, start the motor 1, and the motor 1 drives the bidirectional threaded rod 1 to rotate, so that the limit plates at both ends move toward the middle, thereby clamping the wood and playing a role of limiting, preventing the wood from tilting during the movement, and also playing a role in adapting to wood of different widths.

[0012] 2. The wood is conveyed to the rolling short column, and the motor three is started. The motor three drives the two-way threaded rod two to rotate. The two-way threaded rod two is threadedly connected with the sliding circular shaft and the sliding member one. At this time, the power mechanism and the transmission mechanism move synchronously to achieve width adjustment, so that the device can adapt to wood of different widths.

[0013] 3. Keep the position of the positioning piece unchanged, slide the outer toothed slide to the specified position, at this time the strip connecting piece slides in the circular slide and the groove of the positioning piece, the distance between the positioning piece and the outer toothed slide is the length of the wood to be detected, which can be freely adjusted according to actual needs, so that the device can sort wood of different lengths, and the square shell penetrated by the strip connecting piece can be controlled.

[0014] 4. The wood passes through monitoring device 2 and monitoring device 1 in turn, so as to detect the length of the wood. When the length of the wood is insufficient, start motor 2, which drives the toothed shaft to rotate, and the toothed shaft engages with the outer toothed slide. At this time, the outer toothed slide rotates, and the rotation of the outer toothed slide drives the square shell to rotate. The square shell between the positioning part and the outer toothed slide rotates, so that the rolling short columns at both ends rotate downward, thereby discharging the insufficient length of wood to the bottom; by controlling the transmission mechanism through the length adjustment mechanism, different numbers of rolling short columns can be rotated downward, thereby meeting the sorting operation of wood with different length requirements.

[0045] The working principle of a wood length selection device of the present invention is as follows:

[0046] Put the plate or columnar wood on the conveying device 1 and convey it forward, start the motor 3-1, the motor 3-1 drives the bidirectional threaded rod 3-2 to rotate, so that the limiting plates 3-3 at both ends move toward the middle, so as to clamp the wood and play a role of limiting, avoiding the wood from tilting during the movement, and also playing a role of adapting to wood of different widths.

[0047] The wood is conveyed to the rolling short column 6-3, and the motor three 4-5 is started. The motor three 4-5 drives the two-way threaded rod two 4-6 to rotate. The two-way threaded rod two 4-6 is threadedly connected with the sliding circular shaft 6-1 and the sliding member one 4-1. At this time, the power mechanism 4 and the transmission mechanism 6 move synchronously to achieve width adjustment, so that the device can adapt to wood of different widths.

[0048] Keep the position of the positioning member 5-1 unchanged, slide the outer toothed slide 5-2 to the specified position, at this time, the strip connecting member 5-5 slides in the circular slide 6-2-1 and the groove of the positioning member 5-1, the distance between the positioning member 5-1 and the outer toothed slide 5-2 is the length of the wood to be detected, which can be freely adjusted according to actual needs, so that the device can sort wood of different lengths, and the square shell 6-2 penetrated by the strip connecting member 5-5 can be controlled.

[0049] The wood passes through monitoring device 2 5-4 and monitoring device 1 5-3 in turn, so as to detect the length of the wood. When the length of the wood is insufficient, motor 2 4-3 is started, and motor 2 4-3 drives the toothed shaft 4-2 to rotate. The toothed shaft 4-2 is meshed with the outer toothed slide 5-2. At this time, the outer toothed slide 5-2 rotates, and the rotation of the outer toothed slide 5-2 drives the square shell 6-2 to rotate. The square shell 6-2 between the positioning member 5-1 and the outer toothed slide 5-2 rotates, so that the rolling short columns 6-3 at both ends rotate downward, thereby realizing the discharge of insufficient length wood to the bottom; by controlling the transmission mechanism 6 through the length adjustment mechanism 5, different numbers of rolling short columns 6-3 can be realized to rotate downward, thereby meeting the sorting operation of wood with different length requirements.
