Description

Technical Field

[0001] This invention relates to the field of wood panel production technology, and more specifically to a combined wood panel cutting device. Background Technology

[0002] Wooden flooring is widely used due to its unique natural texture and color. Indoor floors are often made up of several pieces of wooden flooring spliced ​​together. When walking on it, the softness and elasticity of the wooden flooring provide a comfortable feeling underfoot.

[0003] Wooden flooring is made by cutting wooden blocks into sections. Workers often measure and mark lines on the wooden blocks, then place the blocks in front of a circular saw blade to align the lines with the blade. By pushing the blocks into contact with the saw blade, the blocks are cut into wooden flooring of the same size.

[0004] However, when cutting wood, the wood block is placed in front of the saw blade, and the saw blade is aligned with the drawn lines. The wood block is then manually pushed to make contact with the saw blade, thus cutting the wood into appropriate sizes. Because the edges of the wood are relatively sharp when it is not processed, and there are fine needle-like wood chips at the edges and corners, it is easy to prick one's hands when handling the wood manually during the cutting process, resulting in hand injuries.

[0041] The following are specific embodiments of the present invention, which, together with the accompanying drawings, will further describe the technical solution of the present invention.

[0042] like Figure 1-10 As shown, a combined wood flooring cutting device includes a wood board 3, and further includes:

[0043] The base frame 1 has a support plate 6 on it, and an auxiliary pressure unit 2 that cooperates with the wooden board 3 is slidably mounted on the support plate 6.

[0044] The cutting unit 5 is disposed on the support plate 6, and the cutting unit 5 includes a cutting strip 53, which cuts the wooden board 3.

[0045] Conveying unit 4 is mounted on support plate 6. Conveying unit 4 includes support block 45 and transmission component 44 which is rotatably arranged in a linear array on support block 45. Transmission component 44 rotates to control the wooden board 3 to slide on support plate 6.

[0046] A bracket 411 is provided on the support block 45, and a first rotating rod 412 is rotatably provided on the bracket 411. A chamfering wheel 413 that cooperates with the wooden board 3 is symmetrically provided on the first rotating rod 412. The chamfering wheel 413 rotates to rub the edge of the wooden board 3.

[0047] Specifically, the base frame 1 is assembled from multiple horizontal and vertical profiles, which greatly improves the stability of the base frame 1. A baffle is installed between each profile to shield the internal parts of the device. The support plate 6 has multiple mounting holes, through which bolts are used to fix the support plate 6 to the base frame 1. When the wooden board 3 needs to be cut, the wooden board 3 is placed on the support plate 6 so that the support plate 6 connects with the transmission component 44. Simultaneously, the auxiliary pressure unit 2 presses the wooden board 3 to better facilitate its transport between the two transmission components 44. The transmission component 44 rotates to control the wooden board 3 to slide close to and contact the cutting strip 53 on the support plate 6 for cutting. During the cutting process, the edge of one side of the wooden board 3 will contact the chamfering wheel 413. At this time, the chamfering wheel 413 is in a rotating state to chamfer and grind the edge of the wooden board 3, thereby reducing the phenomenon of the wooden board 3 piercing the hand after the cutting is completed. Furthermore, the bracket 411 is snapped onto the support block 45. The bracket 411 can be removed so that the chamfering wheel 413 can be used alone to grind the various corners of the wooden board 3.

[0048] As a further embodiment of the present invention, a first motor 42 is provided on one side of the support block 45, and a sliding plate 451 is provided on the other side. The output end of the first motor 42 is provided with a drive wheel 43 and a second bevel gear 417 in sequence. A transmission belt 444 is provided between the drive wheel 43 and the transmission member 44. One end of the first rotating rod 412 is provided with a first bevel gear 416 that meshes with the second bevel gear 417.

[0049] Specifically, the transmission component 44 includes a transmission wheel 441, a second rotating rod 440, and a conveying wheel 442 mounted on the second rotating rod 440. The transmission wheel 441 is mounted on the second rotating rod 440 and meshes with the transmission belt 444, so that the first motor 42 controls the rotation of the drive wheel 43, and simultaneously controls the rotation of the transmission wheel 441 through the transmission belt 444, that is, controls the rotation of the conveying wheel 442 to convey the wooden board 3. In addition, a rubber sleeve 443 is engaged on the conveying wheel 442 to improve the conveying wheel 442's contact with the wooden board. In terms of the conveying effect of 3, during the rotation of the first motor 42, the second bevel gear 417 will mesh with the first bevel gear 416 to rotate, thereby driving the chamfered wheel 413 on the first rotating rod 412 to rotate. The two chamfered wheels 413 can move on the first rotating rod 412 to adjust the distance between them to adapt to wooden boards 3 of different thicknesses. The number of teeth of the second bevel gear 417 is less than the number of teeth of the first bevel gear 416, that is, the rotation speed of the chamfered wheel 413 is greater than the rotation speed of the conveying wheel 442.

[0050] As a further embodiment of the present invention, the cutting unit 5 includes a mounting plate 56, a support frame 51, and a first clamping member 52 disposed on the support frame 51. The mounting plates 56 are symmetrically disposed on the base frame 1, and a second clamping member 54 is disposed between the mounting plates 56. The cutting strip 53 is disposed between the first clamping member 52 and the second clamping member 54.

[0051] Specifically, the support frame 51 is assembled from a top plate and two side plates 513. A triangular block 512 is provided between the side plates 513 and the top plate. The triangular block 512 improves the stability of the support frame 51. A limiting groove 511 is provided on the support frame 51. The first clamping member 52 slides in the limiting groove 511. The mounting plate 56 is set on the base frame 1. A second screw 561 and a connecting rod 562 are arranged in sequence between the mounting plates 56. The second screw 561 rotates to control the second clamping member 54 to slide on the connecting rod 562. The corresponding first clamping member 52 can slide in the limiting groove 511 and align with the second clamping member 54, thereby adjusting the cutting width of the cutting strip 53 on the wooden board 3.

[0052] As a further embodiment of the present invention, the first clamping member 52 includes a first slider 527 that slides on the support frame 51. A slide rod 521 is slidably disposed at the axis of the first slider 527. A second spring 522 that cooperates with the first slider 527 is disposed at one end of the slide rod 521, and a locking block 526 that contacts the cutting strip 53 is disposed at the other end.

[0053] Specifically, the first slider 527 is provided with a threaded portion 5271, and a rotating sleeve 523 is provided on the threaded portion 5271. One end of the slider 521 is engaged with a limit sleeve (such as...). Figure 5 As shown, the second spring 522 is located on the rotating sleeve 523 and pushes against the limiting sleeve, causing the slide rod 521 to slide along the first slider 527. The other end of the slide rod 521 is rotatably provided with a first screw 525, which is threadedly connected to the locking block 526. The locking block 526 is controlled to slide on the slide rod 521 by the first screw 525 to clamp and fix the cutting strip 53. When the cutting strip 53 is installed on the slide rod 521, the rotating sleeve 523 can be rotated to increase or decrease the squeezing force of the second spring 522 on the limiting sleeve, so that the cutting strip 53 is in a suitable taut state, to prevent the cutting strip 53 from shaking if it is installed too loosely, or from easily deforming if it is installed too tightly, or from easily breaking after cutting for a long time.

[0054] As a further embodiment of the present invention, a connecting plate 524 is provided on one side of the first slider 527. A stabilizing wheel 5244 is symmetrically slidably arranged on the connecting plate 524 and slides toward the cutting strip 53. A liquid outlet groove 5245 is opened on the stabilizing wheel 5244. A liquid storage box 5242 that cooperates with the liquid outlet groove 5245 is provided on the connecting plate 524. A third spring 5243 is provided between the stabilizing wheel 5244 and the connecting plate 524.

[0055] Specifically, a triangular support frame 51 is provided on the connecting plate 524 to improve the stability of the connecting plate 524. A groove is provided at the end of the connecting plate 524, and a fixing block is provided at the axis of the stabilizing wheel 5244. The fixing block slides in the groove. After the cutting strip 53 is fixed, the elastic force of the third spring 5243 pushes the stabilizing wheel 5244 to contact the cutting strip 53. Under the compression of the two stabilizing wheels 5244, the cutting strip 53 is reduced from shaking during the cutting process, improving the flatness of the cutting of the wood board 3. At the same time, during the cutting process, the cutting strip 53 will drive the stabilizing wheel 5244 to rotate, so that the coolant in the liquid storage box 5242 is drawn to the cutting strip 53 through the liquid outlet 5245 to cool the cutting strip 53 and reduce the phenomenon of discoloration of the wood cutting strip due to overheating of the cutting strip 53.

[0056] As a further embodiment of the present invention, the second clamping member 54 includes a second slider 541 and a second motor 55 disposed on the second slider 541. The output end of the second motor 55 is engaged with a swing rod 543. The second slider 541 slides between the mounting plates 56. A push block 545 is slidably disposed on the second slider 541. The push block 545 has a groove 547 that cooperates with the swing rod 543.

[0057] Specifically, both the first motor 42 and the second motor 55 are model number MHMF042L1U2M2. The second motor 55 serves as the power source for the cutting strip 53. When the cutting strip 53 is installed between the first clamping member 52 and the second clamping member 54, the second motor 55 controls the swing rod 543 to rotate on the second slider 541, thereby driving the push block 545 to slide reciprocally in the vertical direction. This allows the cutting strip 53 to cut the wooden board 3. Furthermore, eccentric holes 542 are linearly arrayed on the swing rod 543. An interlocking component is installed in the eccentric hole 542 and slides in the slide groove 547. The interlocking component is engaged with different eccentric holes 542, thereby changing the up-and-down sliding range of the push block 545, which in turn changes the cutting frequency of the cutting strip 53. A limiting part 544 is provided on the second slider 541, and a cover plate 546 is provided on the limiting part 544. The push block 545 is located between the limiting part 544 and the cover plate 546, thereby restricting the sliding direction of the push block 545, so that it can only slide in the vertical direction on the upper seat of the second slider 541.

[0058] As a further embodiment of the present invention, a top block 571 is provided on the mounting plate 56, a telescopic guard plate 572 is provided on the top block 571, and a blocking block 573 that cooperates with the push block 545 is provided on the telescopic guard plate 572.

[0059] Specifically, the telescopic guard plate 572 is composed of multiple sliding plates. During the movement of the second slider 541, the telescopic guard plate 572 slides in conjunction with the push block 545. During the cutting of the wood board 3, a large amount of debris is generated. This debris falls along the telescopic guard plate 572 into the collection box 11 for storage, facilitating subsequent sawdust cleaning. Furthermore, during the up-and-down movement of the push block 545, one side of the push block 545 continuously touches the telescopic guard plate 572 (e.g., ...). Figure 8 As shown), so that the telescopic guard plate 572 vibrates on the top block 571, thereby improving the sliding effect of wood chips on the telescopic guard plate 572.

[0060] As a further embodiment of the present invention, the auxiliary pressure unit 2 includes a slide 21, a hollow block 29 is slidably disposed on the slide 21, an auxiliary pressure wheel 28 is slidably disposed on the hollow block 29, and a first spring 27 is disposed between the auxiliary pressure wheel 28 and the hollow block 29.

[0061] Specifically, the slide 21 has a linear array of locking holes 26. Hollow blocks 29 are fixed to the slide 21 by the cooperation of locking rods 22 and locking holes 26, thereby determining the position of hollow blocks 29. At least three sets of hollow blocks 29 are provided. During the sliding of the wooden board 3, the worker holds the grip part 25 to push the slide 21 to slide on the support plate 6 and move closer to the wooden board 3 until the auxiliary pressure roller 28 contacts the side wall of the wooden board 3. The elastic pushing force of the first spring 27 gives the wooden board 3 a certain pre-pressure effect, so that the wooden board 3 is prevented from deviating during the cutting or conveying process.

[0062] As a further embodiment of the present invention, a locking rod 24 is provided on the slide 21, and a pressing block 23 is provided on the locking rod 24. The pressing block 23 is a rubber block. When the slide 21 is in a certain position, the locking rod 24 can be rotated so that the pressing block 23 is in contact with the top surface of the support plate 6, and the rubber block increases the friction between the pressing block 23 and the support plate 6.

[0063] As a further embodiment of the present invention, the support plate 6 is provided with a cutting groove 61 and a guide groove 62. The cutting groove 61 is provided with an inclined part, and the cutting strip 53 slides in the cutting groove 61. The guide groove 62 cooperates with the auxiliary pressure unit 2 and restricts the sliding direction of the slide 21. The width of the cutting groove 61 is greater than the width of the cutting strip 53. When the wood board 3 is cut, the wood chips will fall from the cutting groove 61 onto the telescopic guard plate 572 and then fall into the collection box 11 along the telescopic guard plate 572. The collection box 11 is provided on the base frame 1.

[0064] Workflow:

[0065] When cutting a large batch of wooden boards 3, the following steps are taken according to the thickness, width and height of the wooden boards 3: First, the position of the cutting strip 53 in the cutting groove 61 is adjusted to control the width of the wood being cut. Second, the height of the slide plate 451 is adjusted according to the height to reduce the amount of wood chips that fall into the support block 45 when the wooden boards 3 are cut. Third, the slide 21 is moved so that the auxiliary pressure roller 28 on the hollow block 29 contacts the side wall of the wooden board 3 and applies a certain amount of pressure to it.

[0066] The first motor 42 and the second motor 55 operate synchronously. The first motor 42 controls the rotation of the drive wheel 43 and the second bevel gear 417 to drive the rotation of multiple conveyor wheels 442 through the transmission belt 444. This allows the wooden board 3 to be held close to the cutting strip 53 by the conveyor wheels 442. At the same time, the second bevel gear 417 meshes with the first bevel gear 416 to rotate, thereby controlling the rotation of the chamfering wheel 413 on the first rotating rod 412 to chamfer the cut wooden board 3, reducing the risk of damage to the hands from sharp parts on the wooden board 3. The second motor 55 controls the rotation of the swing rod 543 to make the push block 545 slide back and forth on the second slider 541, thereby driving the cutting strip 53 to cut the wooden board 3. This device reduces the manual pushing of the wooden board 3 during cutting and improves the cutting efficiency of the wooden board 3.

[0067] The technical solutions of the present invention described above provide solutions that are significantly different from those of the prior art, addressing the problem that existing technical solutions are too simplistic. The parts not covered in this application are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0068] The technical solutions in the above embodiments have clearly and completely described the content of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
