Abstract
Description
Technical Field
[0001] This utility model relates to the field of flooring processing, specifically a flooring cutting device. Background Technology
[0002] In the wood flooring processing industry, the cutting process is a key step in ensuring the dimensional accuracy and edge quality of the flooring.
[0003] Existing cutting devices mostly use single-sided fixed clamps or simple baffles to restrict the lateral displacement of the floorboards. The clamping force is unevenly distributed, which can easily cause the floorboards to skew during feeding. Single-sided clamping cannot effectively control the flatness of the floorboards, and dimensional deviations are easily generated during cutting. Utility Model Content

An adjustment component is connected between the connecting frame, the horizontal column, and the middle column. There is a cutting mechanism on the rear side of the top of the base frame. A slit is opened on the rear side of the top of the base frame.
[0007] The adjustment assembly includes two guide rods, which are vertically fixed to the middle of the front and rear sides of the top of the connecting frame. The guide rods extend upward through the horizontal column and slide with the horizontal column. Springs are sleeved on the guide rods, and the two ends of the springs abut against the horizontal column and the outer wall of the connecting frame, respectively. A threaded rod is fixedly connected to the middle of the top of the connecting frame. The threaded rod extends upward through the outer wall of the intermediate column and slides with the intermediate column. An adjusting nut is threaded onto the outer wall of the threaded rod and abuts against the top of the outer wall of the intermediate column.
[0008] The cutting mechanism includes a cutting machine. A rotating rod is fixedly connected to the right side of the cutting machine's outer casing. A fixed seat is fixedly connected to the rear side of the right side wall of the base frame. The middle part of the rotating rod is rotatably connected to the top of the fixed seat. A tension spring is hung on the right end of the rotating rod. The bottom end of the tension spring is hung on the bottom of the right outer wall of the fixed seat. A pressure handle is fixedly connected to the left side of the cutting machine's outer casing.
[0009] A bellows tube is sleeved on the outer wall of a two-way lead screw. The bellows tube is located between two sliders and between sliders and the inner wall of the base frame.

[0010] The beneficial effects of this utility model are:
[0011] This utility model uses a bidirectional lead screw to drive the two clamping frames to move synchronously, ensuring that the floor is centered and the clamping force is uniform, thus avoiding cutting errors caused by unilateral offset.
[0012] The combination of spring and adjusting nut design ensures both flexible pressing of the pressure roller onto the floor and allows for manual adjustment to accommodate floor thicknesses.
[0013] The pressure roller and clamping roller work together to achieve three-dimensional fixation with lateral clamping and longitudinal pressing, which greatly improves the stability of feeding. Attached Figure Description

Two support rods 14 are vertically fixedly connected to the left and right sides of the top of the base frame 1. The four support rods 14 are distributed in a rectangle. A horizontal column 15 is fixedly connected between the tops of the two support rods 14. A middle column 16 is fixedly connected between the middle outer walls of the two horizontal columns 15. A connecting frame 17 is located below the middle column 16. Several pressure rollers 22 are rotatably connected between the left and right inner walls of the connecting frame 17. An adjustment component is connected between the connecting frame 17, the horizontal column 15, and the middle column 16. A cutting mechanism is located on the rear top side of the base frame 1. A slit 28 is opened on the rear top side of the base frame 1.
[0022] The adjustment assembly includes two guide rods 18, which are vertically fixed to the middle of the front and rear sides of the top of the connecting frame 17, respectively. The guide rods 18 extend upward through the horizontal column 15 and slide in contact with the horizontal column 15. A spring 19 is sleeved on the guide rod 18, and the two ends of the spring 19 abut against the outer wall of the horizontal column 15 and the connecting frame 17, respectively. A threaded rod 20 is fixedly connected to the middle of the top of the connecting frame 17.

[0025] The floorboard to be cut is placed on the feeding roller 3 of the base frame 1. The feeding roller 3 can roll freely, which facilitates the back and forth movement of the floorboard. At this time, the floorboard is located below the connecting frame 17, and the pressure roller 22 is pre-pressed on the floorboard surface by the spring 19 to provide initial clamping force.
[0026] Rotating the throttle 12 drives the bidirectional lead screw 5 to rotate. Since the threads at both ends of the bidirectional lead screw 5 are in opposite directions, the two clamping frames 6 move synchronously towards the middle along the guide rail 4 via the slider 2 9, thereby achieving symmetrical clamping of the left and right sides of the floor.
[0027] The connecting plate 7 at the bottom of the clamping frame 6 cooperates with the guide rail 4 through the slider 8 to ensure smooth movement; the clamping roller 10 inside the clamping frame 6 contacts the side of the floor to prevent lateral displacement.

[0029] The pressure roller 22 is suspended inside the connecting frame 17 by the guide rod 18 and the spring 19, with the spring 19 providing the basic clamping force.
[0030] Rotating the adjusting nut 21 can adjust the extension length of the threaded rod 20, further changing the pressure of the pressure roller 22 on the floor, adapting to flooring of different thicknesses or materials.
[0031] The floor is pushed backward, and the feeding roller 3 assists in the smooth backward conveying of the floor. The clamping roller 10 and the pressure roller 22 together restrict the displacement of the floor to ensure the straightness of the feeding.
[0032] When the rear end of the floor reaches the cut position 28, the pressure handle 27 is pressed down to make the cutting machine 23 rotate around the rotating rod 25, the cutting blade cuts into the floor downwards, the tension spring 26 provides the restoring force, and the cutting machine 23 is automatically lifted after the cutting is completed.
[0033] Corrugated pipe 29 and corrugated pipe 30 respectively wrap the bidirectional lead screw 5 and guide rail 4 to prevent cutting debris or dust from entering the sliding parts and extend the service life of the equipment.
[0034] This utility model only protects the mechanical parts; the functions implemented by the software control part are not within the scope of protection of this utility model.
