Description

Technical Field

[0001] This utility model relates to the field of foam board processing technology, and in particular to a foam board cutting mechanism. Background Technology

[0002] When cutting a large piece of foam board into multiple smaller pieces, the foam template is first placed on the workbench, with the cutting edge of the template positioned in a slide rail on the workbench. The chain drives the cutting blade to move along the slide rail, and the blade cuts into the foam template, dividing it. However, the cutting blade encounters significant resistance as it moves within the foam template, resulting in uneven cuts and reduced product quality. Utility Model Content

[0003] The purpose of this invention is to provide a foam board cutting mechanism, which has the advantage of reducing the resistance of the foam board to the cutter during cutting.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A foam board cutting mechanism includes a worktable with a slide rail along its width. Mounting brackets are fixedly connected to both ends of the slide rail on the worktable. A moving mechanism is provided between the two mounting brackets. The moving mechanism is connected to a mounting base. A second motor is fixedly connected to the mounting base. A rotating rod is fixedly connected to the output shaft of the second motor. A connecting rod is hinged to the other end of the rotating rod. A second connecting rod is hinged to the end of the first connecting rod. The second connecting rod is vertically slidably connected to the mounting base. A cutting blade is fixedly connected to the end of the second connecting rod.

[0006] Using the above technical solution, the foam template is placed on the worktable, covering the slide. The moving mechanism drives the mounting base to move along the slide, and the mounting base drives the cutter to move horizontally. At the same time, motor two drives the rotating rod to rotate, and the rotating rod drives the cutter to move vertically up and down through the connecting rod, piercing into the foam board and cutting through it. This reduces the resistance of the foam template to the cutter, making the cut smoother and resulting in a flatter cut.

[0007] Preferably, the moving mechanism includes a motor, sprockets, a chain, and guide rods. The motor is fixedly connected to one of the mounting brackets. There are two sprockets, which are rotatably connected to the upper parts of two mounting brackets respectively. The two sprockets are connected to each other via the chain drive. The motor is connected to the sprocket on its mounting bracket via a coupling. The mounting base is fixedly connected to the chain. There are two guide rods, which are horizontally located between the two mounting brackets. The two ends of the guide rods are fixedly connected to the side walls of the two mounting brackets respectively. The two guide rods pass through the mounting base, and the mounting base is slidably connected to the guide rods.

[0008] Using the above technical solution, the motor drives the chain to rotate, the chain pulls the mounting base along the guide rod and slides, and the mounting base drives the cutter to move horizontally.

[0009] Preferably, limit strips are fixedly connected to the upper part of the two sides of the workbench.

[0010] Using the above technical solution, the foam template is placed between the limiting strips on both sides of the workbench, and the two sides of the foam board are in contact with the limiting strips to limit the foam template and prevent it from moving during cutting.

[0011] Preferably, the device also includes a baffle plate, which is L-shaped. One part of the baffle plate is parallel to the limiting strip and in contact with the limiting strip, while the other part is perpendicular to the limiting strip. The limiting strip is fixedly connected to the limiting strip by a fastener.

[0012] Using the above technical solution, according to the required length of the bubble template, the baffle is moved and the position between the baffle and the slide is adjusted. Then the baffle is fixed by the fastener. The bubble template is then placed on the worktable on both sides of the slide so that the end of the bubble template contacts the baffle. The cutting blade cuts off the part of the bubble template located between the baffle and the slide. The cut-off part is the required size.

[0013] Preferably, the fixing element is a clamp, and the clamp jaws clamp the baffle and the limiting strip.

[0014] Using the above technical solution, the baffle is clamped onto the limiting strip by clamps.

[0015] Preferably, the assembly also includes bearings, with each mounting bracket having two bearings fixedly connected to it. The two bearings located on the same mounting bracket are respectively located on both sides of the sprocket, and the sprocket is fixedly connected to the inner ring of the bearing via a rotating shaft.

[0016] By adopting the above technical solution, the friction between the sprocket and the mounting bracket is reduced, making its rotation more stable. Attached Figure Description

A slide rail 2 is provided along the width of the workbench 1. Mounting brackets 3 are fixedly connected to both ends of the slide rail 2. Two bearings 16 are fixedly connected to each of the two mounting brackets 3. A sprocket 4 is positioned between the two bearings 16 on the same mounting bracket 3. Rotating shafts are fixedly connected to both sides of the sprocket 4 and are fixedly connected to the inner rings of the bearings 16. The two sprockets 4 are connected by a chain 5. A motor is fixedly connected to one of the mounting brackets 3. The motor is connected to the sprocket 4 on the mounting bracket 3 via a coupling. A mounting base 6 is fixedly connected to the chain 5. The two mounting brackets 3... Two guide rods 7 are fixedly connected between the two parts. The two guide rods 7 pass through the mounting base 6. The mounting base 6 is slidably connected to the guide rods 7. The mounting base 6 is fixedly connected to the second motor 8. The output shaft of the second motor 8 is fixedly connected to the rotating rod 9. The other end of the rotating rod 9 is hinged to the first connecting rod 10. The end of the first connecting rod 10 is hinged to the second connecting rod 11. The second connecting rod is vertically slidably connected to the mounting base 6. The end of the second connecting rod 11 is fixedly connected to the cutter 12. It also includes a baffle 14 and a clamp 15. The baffle 14 is integrally formed with a connecting piece. The connecting piece is L-shaped. There are two baffles 14 located on the upper two sides of the worktable 1 and slidably connected to the worktable 1. The sides of the connecting piece contact the surface of the worktable 1 and the surface of the limiting strip 13, respectively. The clamp 15 is used to fix the baffle 14 to the worktable 1.

[0024] Working principle: Based on the required cutting length of the foam template, loosen the clamp 15, move the baffle 14, adjust the position between the baffle 14 and the slide 2, then clamp the connecting piece and the limiting piece with the clamp 15 to fix the baffle 14. Place the foam template between the limiting strips 13 on both sides of the workbench 1, and cover the slide 2 with the foam board. Move the foam board so that one end of the foam template contacts the baffle 14. Motor 1 drives the chain 5 to rotate, and the chain 5 pulls the mounting base 6 to move along the slide 2. The mounting base 6 drives the cutter 12 to move horizontally. At the same time, motor 2 drives the rotating rod 9 to rotate. The rotating rod 9 drives the cutter 12 to move vertically up and down through the connecting rod, piercing into the foam board and cutting in the foam board, cutting off the foam template. This reduces the resistance of the foam template to the cutter 12, making the cutting smoother and resulting in a flatter cut.
