Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of building material cutting, and particularly relates to a building material cutting device. BACKGROUND

[0002] When cutting building boards such as gypsum board, cement fiber board and wood composite board, a desktop circular saw cutting device is generally used. Such a device uses a high-speed rotating circular saw blade as the cutting main body, and a motor drives the saw blade to continuously rotate through a main shaft. The board is pushed to the blade after being placed on the workbench, and the cutting is completed by the continuous teeth on the outer periphery of the saw blade. The device has simple structure and low cost, and has become the most common cutting form in the industry. However, such a device has the following shortcomings:

[0003] 1. The cutting depth of the circular saw blade is limited by the diameter rigidity. When the thickness of the board is close to or exceeds the radius of the saw blade, a larger diameter saw blade must be replaced or the board must be cut twice, which reduces the cutting efficiency.

[0004] 2. The difference in linear speed at different radii of the saw blade will cause uneven cutting amount in the depth direction of the cut, which is easy to produce surface burrs, edge collapse and bevel cutting, and subsequent additional polishing and finishing are required.

[0005] 3. The circular saw blade is bolted to the main shaft through a flange plate. When replacing, special tools must be used to disassemble and assemble the nuts, which is complicated and time-consuming, and cannot meet the needs of fast-paced construction for efficient cutting. SUMMARY

The strip saw 200 is long strip structure extending along Z direction, including cutting section 210 for cutting material and the assembly section 220 located at the both ends of cutting section 210, the strip saw 200 passes through deck 110, and the assembly section 220 of its upper end is located above deck 110, and the assembly section 220 of lower end is located below deck 110. The design of long strip strip saw 200 breaks through the cutting depth limitation caused by fixed diameter of traditional circular saw blade, so that the equipment can stably cut a variety of thickness specifications of building materials at one time, and the edge line speed is consistent, so as to form uniform and smooth cutting surface on the whole cutting depth, significantly reduce surface burr and edge collapse.

[0039] The drive limiting structure is provided above and below the deck 110, and each drive limiting structure includes an X-direction limiting assembly 300, a Y-direction limiting drive assembly 400 and a plate rack 500.

[0040] The X-direction limiting assembly 300 is used for limiting the displacement of the corresponding assembly section 220 in the X-direction, and includes two groups of Y-direction limiting wheels 310 which are parallel to the Y-direction and can rotate. The two groups of Y-direction limiting wheels 310 form an X-direction limiting space for the corresponding assembly section 220 to extend into along the Z-direction. The two groups of Y-direction limiting wheels 310 can form rolling clamping for the assembly section 220, can offset the X-direction movement caused by vibration during cutting in real time, can ensure the stable and reliable connection between the strip saw 200 and the drive limiting structure, can improve the cutting straightness, and can ensure the cutting quality.

[0041] Specifically, the X-direction limiting assembly 300 further includes a limiting seat 320, the Y-direction limiting wheels 310 are rotatably arranged on wheel shafts 311, the limiting seat 320 is provided with a fastening sliding groove 321 extending along the X-direction, the wheel shafts 311 are arranged in the fastening sliding groove 321, so that the Y-direction limiting wheels 310 can move away from or approach the corresponding assembly section 220, and the limiting seat 320 is further provided with a locking pin 322 for extending into the fastening groove to lock the wheel shaft 311. The fastening sliding groove 321 cooperates with the locking pin 322 to reliably limit and lock the assembly section 220, eliminates the shaking of the strip saw 200 during cutting, and maintains long-term stable limiting effect.

[0042] The Y-direction limiting driving assembly 400 comprises a driving motor 410, a gear shaft 420 and an X-direction limiting shaft 430. The gear shaft 420 and the X-direction limiting shaft 430 are parallel to the X-direction and can rotate around themselves. A Y-direction limiting space is formed between the gear shaft 420 and the X-direction limiting shaft 430 for the corresponding assembly section 220 to extend into along the Z-direction. At least one side of the assembly section 220 is provided with a rack 221 extending along the Z-direction. The rack 221 is engaged with the gear shaft 420. The driving motor 410 drives the gear shaft 420 to rotate, so as to drive the rip saw 200 to reciprocate linearly along the Z-direction to complete the cutting. The plate frame 500 is used for mounting the X-direction limiting assembly 300 and the Y-direction limiting driving assembly 400. The plate frame 500 is provided with an open slot 510 corresponding to the Y-direction limiting space penetrating along the Z-direction, so that the rip saw 200 can be pulled out or inserted from the open slot 510 along the Z-direction, to realize quick replacement. No fasteners such as screws are required in the whole process. The loosening, alignment and locking steps are completely eliminated. The downtime for maintenance is greatly shortened, and the risk of positioning failure caused by loosening of threads is avoided.

[0043] As an embodiment of the present application, referring to Figures 6 to 8 , the plate frame 500 is provided with an X-direction sliding rail 330 extending along the X-direction. The limiting seat 320 is slidingly connected with the X-direction sliding rail 330. The X-direction size of the open slot 510 is adapted to the X-direction size of the X-direction sliding rail 330. The Y-direction two sides of the limiting seat 320 are provided with locking clamps 323. The locking clamps 323 fix the position of the limiting seat 320 by clamping the plate frame 500. The locking clamps 323 are of a conventional vice structure, and thus the specific structure thereof will not be described herein. In this embodiment, the limiting seat 320 is integrally provided as a structure capable of sliding along the X-direction, so that an operator can adjust the relative position of the rip saw 200 in the X-direction according to the width of the material or the cutting position, without the need to adjust the equipment.

[0044] To match the slidable design of the limiting seat 320, referring to Figure 9 , the table plate 110 comprises an adjusting plate 120 and plate bodies 130 located on the Y-direction two sides of the adjusting plate 120. The adjusting plate 120 is provided with a through slot 121 for the rip saw 200 to pass through. The opposite faces of the two groups of plate bodies 130 are provided with adjusting sliding grooves extending along the X-direction. The adjusting plate 120 is provided with sliding blocks 122. The sliding blocks 122 are slidingly matched with the adjusting sliding grooves to adjust the cutting position. The adjusting plate 120 is matched with the adjusting sliding grooves on the fixed plate bodies 130 through the sliding blocks 122, so as to synchronously move along with the X-direction displacement of the limiting seat 320, to keep the through slot 121 and the rip saw 200 always in alignment, avoiding misalignment therebetween. The adjusting plate 120 is also screwed with locking rods 123. One end of the locking rod 123 is provided with a rubber pad 124 contacting the bottom of the plate body 130. The other end of the locking rod 123 is provided with a locking handle 125. The tight design of the locking rod 123 and the rubber pad 124 enables the adjusting plate 120 to keep the position stable under cutting vibration, to ensure that the cutting precision is not affected by the adjustment.

[0045] Further, the X-direction size of the adjusting plate 120 is smaller than the X-direction size of the plate body 130, and the two sides of the adjusting plate 120 in the X-direction are provided with the concertina protective cover 140 to close the gap between the plate bodies 130. The concertina protective cover 140 can form a retractable sealing barrier between the plate bodies 130, effectively blocking the cutting splashing dust and debris from falling onto the driving limiting structure below the table plate 110, affecting the operation of the related mechanism, thereby prolonging the service life of the whole machine and reducing the cleaning and maintenance frequency.

[0046] As another embodiment of the present application, referring to Figure 10 , the strip saw 200 has two or more groups, the number of the X-direction limiting assembly 300 corresponds to the number of the strip saw 200, and all the assembly sections 220 of the strip saw 200 share a corresponding Y-direction limiting driving assembly 400, the axial length of the gear shaft 420 covers all the strip saws 200 and is engaged with the rack 221 of each assembly section 220 at the same time to ensure the synchronization of the reciprocation of the multiple saws. This embodiment can be used for the case of cutting the material into several narrow strips, so that the cutting efficiency is doubled. In addition, the user can adjust the distance between the adjacent strip saws 200 according to the cutting needs, so that multiple finished products with different widths can be obtained at one time, and the auxiliary time of multiple positioning and multiple pushing is saved.

[0047] As another embodiment of the present application, the cutting device further comprises a lifting frame 600, the lifting frame 600 is provided with a lifting driving module 610, the lifting driving module 610 is connected with a Z-direction screw rod 620, and the plate frame 500 is provided with a nut sleeve 520 matched with the Z-direction screw rod 620. The lifting driving module 610 drives the Z-direction screw rod 620 to rotate, and the screw rod is matched with the nut sleeve 520 on the plate frame 500, so as to drive the two groups of driving limiting structures to ascend or descend as a whole.

[0048] This embodiment divides the cutting process into two parts: on the one hand, the driving motor 410 drives the strip saw 200 to reciprocate at a high speed within a small stroke to complete local cutting; on the other hand, the lifting driving module 610 drives the two groups of driving limiting structures to descend or ascend synchronously according to the set pitch, so that each cutting edge of the cutting section 210 participates in the cutting in turn. Therefore, the assembly section 220 does not need to be longer than the cutting section 210, and uniform wear of all the cutting edges can be realized, which saves the material of the strip saw 200 and avoids the waste caused by the idle of most of the cutting edges in the traditional fixed structure.
