[0045] As shown in FIG. 1, Figure 1 The profile sawing machine includes a material pushing device 1, a material placing structure 2, a cutting main machine 3, and a material receiving structure 4, which are sequentially arranged along a first direction. In this embodiment, the first direction can be along the X direction. Of course, it should be noted that based on the requirements of the application scenario, the first direction can also be the Y direction.

[0046] Referring toFigure 1 As shown, the pushing device 1 comprises:

[0047] The pushing gantry 11 is slidingly connected with the pushing linear guide 24 comprised in the feeding structure 2 to be arranged on the feeding rack 21 comprised in the feeding structure 2 to abut against the to-be-sawn profile and push the to-be-sawn profile to move on the feeding rack 21 towards the direction close to the cutting main machine 3.

[0048] The walking power unit 12 is connected with the power transmission unit 25 comprised in the feeding structure 2 to drive the pushing gantry 11 to slide along the pushing linear guide 24 and drive the to-be-sawn profile to be conveyed along the first direction towards the cutting main machine 3 under the rolling of the plurality of conveying roller units 22.

[0049] Specifically, the walking power unit 12 can comprise a servo motor (not shown in the figure), a speed reducer (not shown in the figure), a bearing seat (not shown in the figure) and a gear (not shown in the figure), the gear being engaged with the power transmission unit 25.

Alternatively, in other embodiments, a screw nut mechanism can be used instead of the gear and rack structure.

[0050] Optionally, the number of the walking power units 12 is two sets, and the two sets of the walking power units 12 are arranged on both sides of the pushing gantry 11 along the second direction in mirror image with the first direction as the reference.

[0053] A plurality of conveying roller units 22 are sequentially rotatably arranged on the feeding rack 21 along a second direction, such as the Y direction, for conveying the profile to be sawed. In a specific application, the feeding rack 21 has two horizontal frames arranged along the first direction, and the plurality of conveying roller units 22 are arranged between the two horizontal frames arranged along the first direction. The plurality of conveying roller units 22 can quickly convey the profile to be sawed to a position close to the cutting main machine 3, so as to facilitate sawing by the cutting main machine 3. Here, the second direction is only an example. Specifically, the conveying roller unit 22 can include a bearing seat 221 and a conveying roller 222, the bearing seat is arranged on the feeding rack 21, and the conveying roller is arranged on the bearing seat. The number of conveying roller units 22 is determined according to the profile specification. The closer to the cutting main machine 3, the higher the arrangement density of the conveying roller units 22 on the feeding rack 21.

[0054] A plurality of alignment structures 23 are fixed on the feeding rack 21 along the second direction and are spaced between the plurality of conveying roller units 22, for performing reference side and non-reference side alignment processing on the profile to be sawed, so that the profile to be sawed can move along the first direction towards the cutting main machine, thereby ensuring the directionality of sawing and ensuring that the profile block obtained by sawing does not have a bevel, thereby improving the yield of sawing. The specific structure of the alignment structure 23 is described in detail in Figure 4

[0055] The pushing linear guide rail 24 is arranged on the feeding rack 21 and is in sliding connection with the pushing gantry 11 of the pushing device 1, so that the pushing device 1 slides along the pushing linear guide rail 24, thereby cooperating with the conveying roller unit 22 to quickly move the profile to be sawed as a whole towards the position close to the cutting main machine 3, thereby improving the efficiency of sawing.

[0056] The power transmission unit 25 is connected with the walking power unit 12 of the pushing device 1, so that the pushing device 1 slides along the pushing linear guide rail 24 under the driving of the walking power unit 12. Specifically, the power transmission unit 25 can be a rack, and the rack is in meshing connection with the above-mentioned gear, thereby reducing the difficulty of structural design and improving the compactness of structural design.

[0057] Of course, in other embodiments, other transmission modes can also be used, which can be determined according to the application scene.

[0058] Referring to Figure 4 Each alignment structure 23 includes:

[0059] An alignment seat 231 is mounted on the feeding rack 21.

[0060] ​The reference side alignment unit 232 is installed at one end of the alignment seat 231 and is used to move along the second direction to perform reference side alignment processing on the profile to be sawed;

[0061] The non-reference side alignment unit 233 is installed at the other end of the alignment seat 231 and is used to move along the second direction to perform non-reference side alignment processing on the profile to be sawed.

[0062] Optionally, the reference side alignment unit 232 comprises a reference side sliding block 2321, a reference side pressing block 2322, a reference side sliding rail 2323 and a first bolt roller bearing 2324. The reference side sliding rail is arranged along the second direction and the discharge rack 21 is located on the alignment seat 231. The reference side sliding block is used to move along the reference side sliding rail during reference side alignment. The reference side pressing block is used to lock the reference side sliding block on the reference side sliding rail when the reference side sliding block slides to a predetermined position during reference side alignment. The first bolt roller bearing is installed on the reference side sliding block, follows the movement of the reference side sliding block and supports the profile to be sawed to move along the first direction.

[0063] Optionally, the non-reference side alignment unit 233 comprises a non-reference side alignment power unit 2331, a power unit mounting seat 2332, a non-reference side sliding plate 2333, a non-reference side sliding block 2334 and a second bolt roller bearing 2335. The non-reference side alignment power unit 2331 is installed on the power unit mounting seat 2332. The non-reference side sliding plate 2333 is connected to the alignment seat 231 through the non-reference side sliding block 2334 and is connected to the non-reference side alignment power unit 2331 to perform non-reference side alignment. The second bolt roller bearing 2335 is installed on the non-reference side sliding plate 2333 and follows the movement of the non-reference side sliding block 2334 during non-reference side alignment.

[0064] Specifically, the power unit mounting seat 2332 is located at the middle position of the alignment seat 231, so as to ensure a large stroke and enable alignment of a narrow profile.

[0065] In other embodiments, the position relationship between the power unit mounting seat 2332 and the alignment seat 231 is not necessarily at the above-mentioned middle position, and can be determined according to the alignment stroke during alignment processing.

[0066] Specifically, the non-reference side alignment power unit 2331 can be an oil cylinder and the power unit mounting seat 2332 can be an oil cylinder seat. Of course, alternatively, the non-reference side alignment power unit 2331 can be an air cylinder and the power unit mounting seat 2332 can be an air cylinder seat.

[0067] Referring to Figure 5 The cutting host 3 is adjacent to the material placing structure 2, which comprises:

[0068] The first sawing host 31 is used for sawing the to-be-sawn profile material transported to the position of the cutting host 3.

[0069] The second sawing host 32 is arranged below the first sawing host and is used for sawing the to-be-sawn profile material transported to the position of the cutting host 3.

[0070] The material receiving structure 4 is used for receiving the profile material block obtained by sawing the to-be-sawn profile material.

[0071] Optionally, the cutting host 3 further comprises:

[0072] The material supporting table 33 is used for supporting the to-be-sawn profile material carried to the cutting host 3. Exemplarily, the supporting surface of the material supporting table is a steel plate plane, so that the sawing process is more stable.

[0073] The first mounting seat 34 is used for mounting the first sawing host, so that the first sawing host is located above the material supporting table to saw the to-be-sawn profile material transported to the position of the cutting host 3. The direction is from top to bottom.

[0074] The second mounting seat 35 is used for mounting the second sawing host, so that the second sawing host is located below the material receiving structure 4 to saw the to-be-sawn profile material transported to the position of the cutting host 3. The direction is from bottom to top.

[0075] Optionally, the first mounting seat is a cantilever frame arranged along the second direction, and a first sawing linear guide rail 341 is arranged on the cantilever frame. A first sawing sliding block 342 is arranged on the first sawing host, and the first sawing sliding block is in sliding connection with the first sawing linear guide rail 341, so that the first sawing host slides left and right to saw the to-be-sawn profile material, thereby being applicable to a scenario in which the sliding distance of the first sawing host is short. Of course, in another embodiment, if the to-be-sawn profile material is relatively wide and the sliding distance of the first sawing host is relatively long, the first mounting seat is a gantry frame.

[0076] Optionally, the second mounting seat is a lower cutting base arranged below the material receiving structure 4. A second sawing linear guide rail 351 is arranged on the lower cutting base. A second sawing sliding block 352 is arranged on the second sawing host, and the second sawing sliding block is in sliding connection with the second sawing linear guide rail 351, so that the second sawing host slides left and right to saw the to-be-sawn profile material.

[0077] Exemplarily, referring to Figure 4 , the first sawing host 31 can include: a first motor 311, a first speed reducer 312, a first bearing seat 313, and a first saw blade 314. The first motor is connected with the first speed reducer, the first speed reducer is installed on the first bearing seat, and the first bearing seat is connected with the cantilever frame through the pushing linear guide rail 24. The driving force of the first speed reducer is transmitted to the sawing spindle through a gear chain (or a synchronous belt) and drives the first saw blade to rotate for sawing.

[0078] Exemplarily, referring to Figure 4 , and combining Figure 3 , the second sawing host 32 can include: a second motor 321, a second speed reducer 322, a second bearing seat 323, and a second saw blade 324. The second motor is connected with the second speed reducer, the second speed reducer is installed on the second bearing seat, and the second bearing seat is connected with the second mounting seat 35 through the second sawing linear guide rail 351.

[0079] During sawing, the directions of rotation of the saw blades in the first sawing host and the second sawing host can be opposite, so as to realize simultaneous up sawing and down sawing of the profile.

[0080] Compared with a single sawing host for achieving cutting of the same thickness, the single sawing host needs more of the saw blade to protrude, and accordingly the cutting stability is reduced, which is not conducive to the use of the saw blade and reduces the service life of the saw blade. By simultaneously configuring the first sawing host 31 and the second sawing host 32, a stable cutting relationship can be formed between the first sawing host 31 and the second sawing host 32, which is conducive to the use of the first saw blade and the second saw blade and improves the service life of the saw blades.

[0081] Here, it should be noted that in some embodiments, the second sawing host can be used alone for cutting.

[0082] Alternatively, in other embodiments, a lead screw structure or a gear and rack structure can be used to drive the linear motion of the sawing host.

[0083] Referring to Figure 3 , the material receiving structure 4 includes a material receiving frame 41 and casters 42. The material receiving frame is used to hold profile blocks obtained by sawing the profile to be sawed. The casters are arranged below the material receiving frame, so that the material receiving frame is movable.

[0084] Referring to Figure 3 , the profile sawing machine further includes a material pressing structure 5 arranged close to the cutting host 3 to provide a sawing stabilizing force. The sawing stabilizing force enables the first sawing host and the second sawing host to stably saw the profile to be sawed conveyed to the position of the cutting host 3.

[0085] Specifically, the pressing device is provided with a pressing linear slider 51, and the cantilever frame is provided with a pressing linear guide rail 52, the pressing linear slider is in sliding connection with the pressing linear guide rail 52, and the pressing linear slider slides downward along the pressing linear guide rail 52 to press the profile to be sawed during sawing, so that the sawing stability can be provided and the cutting stability is increased.

[0086] Specifically, the pressing device comprises a cylinder 50 and a pressing frame 53, the cylinder is connected with the cantilever frame and the pressing frame, and provides a pressing force to make the pressing linear slider slide downward along the pressing linear guide rail 52. Specifically, the pressing frame has a pressing part, and the pressing linear slider sliding downward along the pressing linear guide rail 52 can make the pressing part probe into the cantilever frame, and approach the cutting position as much as possible, so that the cutting stability is increased.

[0087] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
