[0027] Please see Figure 1-3 The plywood end face grooving machine shown includes a frame 1, on which a grooving device 2, a clamping device 3, a supporting device 4, and an ejecting device 5 are provided. The supporting device 4, grooving device 2, clamping device 3, and ejecting device 5 are all mounted on the frame 1. The grooving device 2 is provided in a set at both ends of the upper part of the frame 1, the clamping device 3 is located between the two grooving devices 2, and the ejecting device 5 is located at one end of the frame 1.

[0028] The grooving device 2 includes two support columns 201, a crossbeam plate 202, and two adjustable grooving components 203. The two support columns 201 are symmetrically arranged on the frame 1 to support the crossbeam plate 202; the crossbeam plate 202 is located at the upper end of the two support columns 201 and is inherently connected to the upper end of the two support columns 201 to form a stable support structure; the two adjustable grooving components 203 are symmetrically arranged on the lower end face of the crossbeam plate 202.

[0029] The adjustable grooving assembly 203 includes a handwheel 203a, a first transmission lead screw pair 203b, a second transmission lead screw pair 203c, a lead screw motor 203d, a connecting frame 203e, a moving seat 203f, a lifting cylinder 203g, a pull plate 203j with a clearance opening 203h, a set of linear guide rail pairs 203k, a motor mounting plate 203m, a grooving motor 203n, and a milling cutter 203p. The first transmission screw pair 203b is located on the lower end face of the crossbeam plate 202, and one end of its transmission screw passes through the adjacent side support column 201 and is connected to the handwheel 203a. By rotating the handwheel 203a, the transmission screw of the first transmission screw pair 203b can be rotated, thereby causing the screw nut seat to drive the connecting frame 203e to move left and right on the lower end face of the crossbeam plate 202, realizing the coarse adjustment of the adjustable slotted assembly 203 in the horizontal direction; the screw nut seat on the first transmission screw pair 203b is inherently connected to the connecting frame 203e. The second transmission screw pair 203c is located at the lower end of the connecting frame 203e. Its transmission screw is connected to the rotating shaft of the screw motor 203d. When the screw motor 203d is working, it drives the transmission screw of the second transmission screw pair 203c to rotate, causing the screw nut seat to drive the moving seat 203f to move horizontally on the lower end face of the connecting frame 203e. This, in turn, drives the motor mounting plate 203m, the slotting motor 203n, and the milling cutter 203p connected to the moving seat 203f to move synchronously. The screw nut seat of the second transmission screw pair 203c is connected to the upper end face of the moving seat 203f. The lifting cylinder 203g is mounted on the movable seat 203f, and its telescopic rod is rotatably connected to one end of the pull plate 203j through a Y-shaped connector. When the lifting cylinder 203g extends or retracts, the pull plate 203j drives the motor mounting plate 203m to move up and down along the linear guide pair 203k, thereby realizing the lifting and lowering of the slotting motor 203n and the milling cutter 203p. A set of linear guide pairs 203k is located on the side of the movable seat 203f away from the lifting cylinder 203g, and its slider is connected to the motor mounting plate 203m, providing guidance and support for the movement of the motor mounting plate 203m. The grooving motor 203n is vertically mounted on the motor mounting plate 203m and its shaft is connected to the milling cutter 203p. The grooving motor 203n drives the milling cutter 203p to rotate at high speed to achieve grooving of the plywood. The end of the pulling plate 203j away from the lifting cylinder 203g passes through the clearance opening 203h and is inherently connected to the motor mounting plate 203m.

[0030] The pressing device 3 includes a support frame 301, a pressing assembly 302, and a side pressing assembly 303. Two pressing assemblies 302 are provided, located at the upper end of the support frame 301. Two side pressing assemblies 303 are provided on the left and right sides of the support frame 301. The pressing assembly 302 includes a pressing cylinder 302a, a pressing connecting plate 302b, and a pressing plate 302c. The cylinder body of the pressing cylinder 302a is inherently connected to the upper end face of the support frame 301 through the pressing plate 302c. Its telescopic rod passes through the support frame 301 and connects to the pressing plate 302c. When the pressing cylinder 302a is working, the telescopic rod extends, driving the pressing plate 302c to move downwards, pressing and fixing the plywood. The side pressure assembly 303 includes a side pressure cylinder 303a and a side pressure plate 303b. The cylinder body of the side pressure cylinder 303a is connected to the support frame 301 through a side connecting plate, and its telescopic rod is connected to the side pressure plate 303b. The side pressure plate 303b is vertically arranged on the upper part of the support device 4. When the side pressure cylinder 303a is working, the telescopic rod extends and drives the side pressure plate 303b to move to the side of the plywood, thereby pressing and fixing the plywood from the side.

[0031] The supporting device 4 includes multiple rollers 401, a set of fixed uprights 402, and a set of guide plates 403. The guide plates 403 are symmetrically arranged on the frame 1. The two ends of the multiple rollers 401 are connected to the fixed uprights 402 via bearings, and the guide plates 403 are respectively set on the sides of the two fixed uprights 402 via bolts and nuts. The multiple rollers 401 are used to support the plywood, making the plywood move more smoothly during movement; the guide plates 403 guide the plywood, ensuring that the plywood moves in the correct direction on the supporting device 4.

[0032] The ejection device 5 includes an ejection cylinder 501, an ejection base 502, and a top plate 503. The cylinder body of the ejection cylinder 501 is mounted on the frame 1 via the ejection base 502, and its telescopic rod is inherently connected to the top plate 503. When the ejection cylinder 501 is working, the telescopic rod extends, driving the top plate 503 to eject the processed plywood from the frame 1.

[0033] Working principle:

[0034] When using this plywood end-face grooving machine, the plywood is first placed on the roller 401 of the support device 4. Under the guidance of the guide plate 403, the plywood accurately enters the processing area. Then, the clamping device 3 is activated, and the telescopic rods of the lowering cylinders 302a of the two lowering components 302 extend, driving the lowering plate 302c to move downward and clamp the plywood from above. At the same time, the telescopic rods of the side pressing cylinders 303a of the two side pressing components 303 extend, driving the side pressing plate 303b to move to the side of the plywood, squeezing and fixing the plywood from the side to ensure that the plywood does not shift during processing.

[0035] Next, according to the grooving requirements of the plywood, by rotating the handwheel 203a, the adjustable grooving assembly 203 is coarsely adjusted horizontally using the first transmission screw pair 203b, so that the milling cutter 203p is approximately at the required grooving starting position. Then, the screw motor 203d is started, and the adjustable grooving assembly 203 is precisely adjusted horizontally using the second transmission screw pair 203c, accurately positioning the milling cutter 203p at the grooving starting point. Afterwards, the lifting cylinder 203g is started, and its telescopic rod extends, driving the motor mounting plate 203m downwards along the linear guide pair 203k via the pulling plate 203j, so that the milling cutter 203p descends to the appropriate grooving depth. At the same time, the grooving motor 203n is started, driving the milling cutter 203p to rotate at high speed.

[0036] During the milling process, the lead screw motor 203d operates continuously, driving the moving seat 203f through the second transmission lead screw pair 203c. This, in turn, causes the motor mounting plate 203m, the grooving motor 203n, and the milling cutter 203p to move synchronously along the required grooving path on the plywood end face, achieving the effect of milling while moving. During the movement, the speed of the lead screw motor 203d can be adjusted according to the actual situation to control the moving speed of the milling cutter 203p. At the same time, the grooving depth of the milling cutter 203p can be adjusted by the lifting cylinder 203g. After grooving one end face is completed, the other end face of the plywood can be grooved in the same way by adjusting the position of the adjustable grooving assembly 203.

[0037] After the grooving of both ends of the plywood is completed, the grooving motor 203n and the lifting cylinder 203g are turned off, causing the milling cutter 203p to rise and reset. Then, the lead screw motor 203d is turned off, the ejection device 5 is started, the extension rod of the ejection cylinder 501 extends, and the top plate 503 pushes the processed plywood out of the frame 1, completing the entire processing flow.

[0038] The embodiments are detailed, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
