Description

Technical Field

[0001] This utility model relates to the field of board processing equipment technology, specifically to a grooving device for the bottom surface of a wooden board. Background Technology

[0002] In the furniture industry, the bottom surface of wood panels often needs to be grooved to fit together with other panels or to install other fasteners. Grooving of wood panels requires a grooving machine, which uses a motor to drive a milling cutter back and forth to create the grooves.

[0003] In existing technology, the machining depth and retraction / advance movement of the milling cutter on a sheet metal grooving machine are usually achieved by two independent adjustment devices. Generally, the milling cutter motor used to drive the milling cutter's movement is mounted on a lifting plate. One lifting device is connected to the lifting plate and can adjust the lifting plate's height and fine adjustment to adjust the milling cutter's machining depth. At the same time, this lifting device and the lifting plate are mounted on a sliding plate. Another lifting device is connected to the sliding plate and is used to drive the sliding plate to move up and down to achieve the milling cutter's advance and retraction movements. This structure requires sliding cooperation between multiple sliding plates and fixed plates, requiring the installation of two sets of slide rails and slider structures on the sliding plates and fixed plates respectively. In addition, multiple sheets need to be assembled inside and out in sequence, making the entire installation process quite cumbersome. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a grooving device for the bottom surface of wooden boards, thereby solving the problem that the existing board grooving machine requires two sets of slide rails and slider structures to be installed on the slide plate and the fixed plate respectively, as well as multiple boards to be combined inside and outside in sequence, resulting in a cumbersome installation process.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This application provides a grooving device for the bottom surface of a wooden board, including a motor and a grooving forming knife, as well as a grooving fixing seat, a front-to-back moving assembly, a lifting cylinder, a lifting bearing seat, a connecting plate, a front-to-back moving slide plate, and a motor height adjusting screw. The motor is fixedly installed on one side of the front-to-back moving slide plate, the front-to-back moving assembly is connected to the front-to-back moving slide plate, and the front-to-back moving assembly is used to drive the front-to-back moving slide plate to move back and forth. The front-to-back moving assembly is fixedly installed on the lifting bearing seat, and the lifting bearing seat and the grooving fixing seat form a lifting sliding connection. The lifting cylinder is fixedly installed on the top of the grooving fixing seat, and the piston rod of the lifting cylinder is connected to the connecting plate. The bottom end of the motor height adjusting screw passes through the connecting plate and is rotatably fixed on the lifting bearing seat. The motor height adjusting screw and the connecting plate form a threaded rotational connection.

[0007] Furthermore, the motor height adjusting screw is rotatably mounted on the lifting bearing seat, and a connecting block is rotatably mounted at the end of the motor height adjusting screw. The connecting block contacts the bottom end face of the lifting bearing seat and is used to prevent the lifting bearing seat from sliding off the bottom end of the motor height adjusting screw.

[0008] Furthermore, the forward and backward moving assembly includes a forward and backward cylinder and a connecting rod. The forward and backward cylinder is fixedly mounted on the lifting bearing seat, and the connecting rod passes horizontally through the lifting bearing seat. The connecting rod and the lifting bearing seat form a sliding connection along the axial direction of the connecting rod. One end of the connecting rod is connected to the piston rod of the forward and backward cylinder, and the other end of the connecting rod is fixedly connected to the forward and backward moving slide plate.

[0009] Furthermore, a horizontal bearing is fixedly installed at the top of the connecting plate, and the motor height adjustment screw is rotated and installed inside the horizontal bearing.

[0010] Furthermore, there is a pair of lifting cylinders, which are symmetrically installed at the bottom of the connecting plate.

[0011] The beneficial effects of this utility model are as follows:

[0012] By employing a grooving device on the bottom of a wooden board, a lifting cylinder is installed at the bottom of the grooving fixing base. The lifting cylinder is connected to a connecting plate, and a motor height adjustment screw is threadedly mounted on the connecting plate. The bottom end of the motor height adjustment screw is rotated and fixedly mounted on a lifting bearing seat. The motor is mounted on the lifting bearing seat via a sliding plate that moves back and forth. When the cutting tool needs to be advanced or retracted, the lifting cylinder drives the connecting plate to move up and down. The connecting plate in the advancing or retracting state then synchronously drives the lifting bearing seat to move up and down via the motor height adjustment screw, realizing the advancement or retraction of the grooving forming tool. When it is necessary to adjust the processing depth of the grooving forming tool, the height can be directly adjusted by rotating the motor. The lead screw can drive the lifting bearing seat to move up and down, thereby adjusting the machining depth of the grooving cutter. In the above structure, since the motor height adjustment lead screw is directly screwed onto the connecting plate, the infeed or retraction of the grooving cutter and the adjustment of the machining depth can be achieved by the lifting movement of the lifting cylinder and the rotation of the motor height adjustment lead screw. At the same time, the installation structure of the motor height adjustment lead screw and the connecting plate is relatively simple, thus solving the problem that the existing plate grooving machine's milling cutter machining groove depth and retraction and infeed adjustment structure requires the installation of two sets of slide rails and slider structures on the slide plate and the fixed plate respectively, as well as the sequential combination of multiple plates inside and outside, resulting in a cumbersome installation process.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0031] See appendix Figure 1 To be continued Figure 4 As shown, this embodiment provides a wood board bottom grooving device 10, including a motor 200, a grooving forming knife 300, a grooving fixing seat 100, a front and rear moving assembly 500, a lifting cylinder 700, a lifting bearing seat 600, a connecting plate 800, a front and rear moving slide plate 400, and a motor height adjusting screw 900.

[0032] In this embodiment, the motor 200 is fixedly installed on the outer side of the front and rear moving slide plate 400, and the grooving forming blade 300 is fixedly installed on the conveying shaft of the motor 200. For example, a grooving forming blade 300 with a grooving width of 30mm-50mm can be used.

[0033] See attached document Figure 3 As shown, the forward and backward moving assembly 500 is connected to the forward and backward moving slide plate 400 and is used to drive the forward and backward moving slide plate 400 to move back and forth relative to the lifting bearing seat 600. Specifically, the forward and backward moving assembly 500 includes a forward and backward cylinder 501 and connecting rods 502. There is a pair of connecting rods 502. The forward and backward cylinder 501 is fixedly mounted on the lifting bearing seat 600. The pair of connecting rods 502 pass horizontally through the lifting bearing seat 600 and are arranged symmetrically up and down. The pair of connecting rods 502 ensures the stability of the forward and backward moving slide plate 400 when the forward and backward cylinder 501 drives the forward and backward moving slide plate 400 to move. The connecting rods 502 and the lifting bearing seat 600 form a sliding connection along the axial direction of the connecting rods 502. One end of the connecting rod 502 is connected to the piston rod of the forward and backward cylinder 501, and the other end of the connecting rod 502 is fixedly connected to the forward and backward moving slide plate 400.

[0034] See attached document Figure 1 and attached Figure 2 As shown, the lifting bearing seat 600 and the slotted fixing seat 100 form a lifting sliding connection. The lifting cylinder 700 is fixedly installed at the top of the slotted fixing seat 100. The connecting plate 800 is disposed above the lifting cylinder 700, and the piston rod of the lifting cylinder 700 is connected to the connecting plate 800. In some embodiments, there is a pair of lifting cylinders 700, which are symmetrically arranged on the bottom of the connecting plate 800. The bottom end of the motor height adjusting screw 900 passes through the connecting plate 800 and is rotatably fixed on the lifting bearing seat 600. The motor height adjusting screw 900 and the connecting plate 800 form a threaded rotational connection. The connecting plate 800 has a threaded hole, and the motor height adjusting screw 900 is installed in the threaded hole. When the motor height adjusting screw 900 is rotated, the motor height adjusting screw 900 rotates relative to the connecting plate 800. Since the connecting plate 800 is fixed to the top of the slotted fixing seat 100, the motor height adjusting screw 900 will move up or down relative to the connecting plate 800 when the motor height adjusting screw 900 is rotated and fixedly installed on the lifting bearing seat 600. Therefore, during the process of the motor height adjusting screw 900 moving up or down, it will synchronously drive the lifting bearing seat 600 to move up or down.

[0035] See attached document Figure 4As shown, when the cutting tool needs to be advanced or retracted, the connecting plate 800 is moved up and down by the lifting cylinder 700. The connecting plate 800, in this state of movement, then synchronously moves the lifting bearing seat 600 up and down via the motor height adjusting screw 900, thus realizing the advancement or retraction of the grooving forming tool 300. In some embodiments, a horizontal bearing 120 is fixedly installed at the top of the connecting plate 800, and the motor height adjusting screw 900 is rotatably installed within the horizontal bearing 120.

[0036] See attached document Figure 2 As shown, the motor height adjusting screw 900 is rotatably mounted on the lifting bearing seat 600. A connecting block 110 is rotatably mounted at the end of the motor height adjusting screw 900. The connecting block 110 contacts the bottom end face of the lifting bearing seat 600. In this way, the connecting block 110 is used to restrict the lifting bearing seat 600 from sliding off the bottom end of the motor height adjusting screw 900. This arrangement ensures that the motor height adjusting screw 900 can rotate on the lifting bearing seat 600 and be fixedly connected.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
