[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1, referring to Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a laser cutting device for processing the transmission structure of a treadmill. The laser cutting device for processing the transmission structure of a treadmill includes a laser cutting machine 1, a pressing component 2, and a guiding component 3.

[0036] By setting up the clamping component 2 and the guiding component 3, the first transmission roller 31 or the second transmission roller 32 can be flexibly driven to lift according to actual processing needs. The first transmission roller 31 is used to meet the overall material (thick plate or thin plate) transmission needs in the transmission structure, and the second transmission roller 32 is used to meet the individual material (strip or roller) transmission needs in multiple transmission structures. Multiple individual materials are separated and can be actively calibrated and aligned, making it well applicable to the processing needs of individual materials of various specifications.

[0037] The gantry 12 and the laser cutting head 13 are both commonly used and known structures in existing laser cutting equipment. Their working principles are existing technologies and can be clearly understood by those skilled in the art, so they will not be described in detail here.

[0038] Example 2, refer to Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, the inner ring of the first clamping ring 361 is fixed with a first protruding rod 3611, the inner ring of the second clamping ring 362 is fixed with a second protruding rod 3621, and a rotating block 366 is rotatably connected to both the first protruding rod 3611 and the second protruding rod 3621.

[0040] A vertical rod 365 is fixed to the inner wall of the second transmission roller 32. A rotating plate 367 is rotatably connected to the vertical rod 365. The two ends of the rotating plate 367 are respectively rotatably connected to two rotating blocks 366.

[0041] A traction seat 368 is rotatably connected to the second protruding rod 3621, and a steel rope 369 is fixed inside the traction seat 368.

[0042] As shown in the attached diagram of the instruction manual. Figure 3 As shown, there are several diverting components 36 evenly distributed on the second transmission roller 32 to meet the requirement of uniform placement of multiple strip-shaped materials.

[0043] As shown in the attached diagram of the instruction manual. Figure 5 As shown, the inner rings of the first clamping ring 361 and the second clamping ring 362 are both protruding and are placed inside the second transmission roller 32. The second transmission roller 32 has a displacement groove 322 for sliding displacement of the first clamping ring 361 and the second clamping ring 362.

[0044] Both the first clamping ring 361 and the second clamping ring 362 are provided with inclined grooves 364, which are used to facilitate the placement of individual materials between the first clamping ring 361 and the second clamping ring 362 when the individual material moves down.

[0045] The other end of steel cable 369 is fixed to the rotating rod 343. It should be noted that the attached diagram in the instruction manual is correct. Figure 3 For example, the second guide frame 341 located in front of the second transmission roller 32 has a fixing block 342, a rotating rod 343, a gear 344, a rack 345 and an auxiliary frame 3451, while the second guide frame 341 located behind the second transmission roller 32 does not have the above structures installed.

[0046] Specifically, a torsion spring 3651 is fixed at the bottom of the rotating plate 367 and sleeved on the vertical rod 365. The bottom end of the torsion spring 3651 is fixed on the vertical rod 365.

[0047] Specifically, the first transmission roller 31 is rotatably connected to the first positioning head 311 at both ends, and the first guide frame 35 is bolted to the machine body 11 for guiding the displacement of the first positioning head 311.

[0048] Specifically, the second transmission roller 32 is fixed with a second positioning head 321 at both ends. The second positioning head 321 is slidably connected to the second guide frame 341 and is used to guide the displacement of the second transmission roller 32.

[0049] Specifically, the connector 33 includes a positioning shaft 332 rotatably connected to the body 11, a storage frame 331 rotatably connected to the positioning shaft 332, a first slide rod 333 and a second slide rod 334 slidably connected inside the storage frame 331, a first spring 335 fixed between the first slide rod 333 and the storage frame 331, and between the second slide rod 334 and the storage frame 331, and a connecting rod 336 rotatably connected to the end of the second slide rod 334 away from the storage frame 331.

[0050] One end of the first slide bar 333 is rotatably connected to the first transmission roller 31, and the other end of the connecting rod 336 is rotatably connected to the second transmission roller 32.

[0051] Specifically, a gear 344 is fixed to one end of the rotating rod 343, and a rack 345 that meshes with the gear 344 is provided on one side of the second guide frame 341.

[0052] An auxiliary frame 3451 is fixed on one side of the rack 345, and an auxiliary groove 3411 for the auxiliary frame 3451 to move is provided on the second guide frame 341.

[0053] In practical applications, the auxiliary frame 3451 is located in the auxiliary groove 3411 and the cross-sectional shape of the auxiliary groove 3411 is T-shaped, which is used to prevent the rack 345 from being displaced at will and disengaging from the gear 344.

[0054] Specifically, the adjusting component 34 also includes an electric push rod 346 bolted to the second guide frame 341, and a bracket 347 is fixed to the output end of the electric push rod 346.

[0055] A second spring 3471 is fitted on the bracket 347. One end of the second spring 3471 is fixed on the bracket 347, and the other end of the second spring 3471 is fixed on the plate 349.

[0056] The top of the pallet 349 is fixed to the second transfer roller 32.

[0057] The pressing block 348 is fixed on the bracket 347, and the support plate 349 is slidably connected to the bracket 347.

[0058] Specifically, the clamping assembly 2 also includes a support frame 21 bolted to the gantry frame 12, and a mounting frame 22 welded onto the support frame 21 for moving together with the gantry frame 12.

[0059] A servo motor 23 is fixed to the top of the mounting frame 22 by bolts. A screw 24 is fixed to the output end of the servo motor 23. A displacement seat 25 is threaded onto the screw 24.

[0060] The rotational speed / position signals of the two laser cutting heads 13 are collected by the feedback element (encoder). The controller (PLC / motion controller / servo driver - not shown in the figure) compares the synchronization deviation of the two laser cutting heads 13 in real time, and then adjusts the output signal through the algorithm to dynamically correct the deviation. The working principle of this part is all existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0061] The bottom end of the screw 24 is smooth and is mounted in the mounting frame 22 through a bearing seat to ensure the rotational stability of the screw 24.

[0062] The displacement seat 25 is slidably connected to the mounting frame 22 and bolted to the air intake component 26. The air intake component 26 includes a hollow frame bolted to the mounting frame 22 and a centrifugal fan screwed into the hollow frame. The air intake end of the centrifugal fan is fixed with an air intake bucket with a filter screen, and the air outlet end of the centrifugal fan is connected to the inner cavity of the hollow frame.

[0063] A hollow gooseneck tube 261 is connected to one side of the hollow frame. An integrated plate 262 is provided on the hollow gooseneck tube 261 with anti-slip sleeve. The tilt angle of multiple hollow gooseneck tubes 261 can be adjusted in a coordinated manner through the integrated plate 262. The characteristics of the hollow gooseneck tube 261 can be used to maintain the adjusted angle after the bending adjustment is completed.

[0064] In actual operation, the integrated plate 262 can also be removed manually, and then the tilt angle of the hollow gooseneck tube 261 can be adjusted separately.

[0065] In actual operation, the centrifugal fan inside the air intake component 26 can be actively controlled to bring the hot gas near the laser cutting into the hollow frame and discharge it through multiple hollow gooseneck tubes 261. This is used to spray the residual hot gas onto the material processing side or the position to be processed, which plays a role in preheating treatment and avoids the deformation of materials, such as thin plate materials, caused by excessive temperature difference.

[0066] As shown in the attached diagram of the instruction manual. Figure 3 As shown, the top of the first transmission roller 31 and the first clamping ring 361 are at a lower horizontal plane than the top of the sawtooth plate 14.

[0067] In use, depending on the type of part to be processed, such as a whole material, the electric push rod 346 is controlled to retract, driving the bracket 347 to move down. Under the connection of the second spring 3471, the tray 349 is linked with the second transmission roller 32 to gradually move down, thereby driving the connecting rod 336 to move down. Under the positioning shaft 332, the first slide rod 333 can gradually move out of the storage frame 331, so that the first transmission roller 31 can gradually move up. Compared with the serrated plate 14, it is convex, which facilitates the placement of the whole material and is conducive to pushing the material inward.

[0068] Similarly, when feeding a single material, the electric push rod 346 is extended to work, and the second transmission roller 32 gradually moves upward, protruding from the serrated plate 14, until the second positioning head 321 is limited by the second guide frame 341 and cannot move upward again. Then the single material is placed between the first clamping ring 361 and the second clamping ring 362 and placed on the transmission ring 363.

[0069] The electric push rod 346 extends further to work, the bracket 347 moves further upward, the second spring 3471 is compressed, and the pressing block 348 gradually moves upward and contacts the rack 345. Under the meshing transmission, the gear 344 drives the rotating rod 343 to rotate, which is used to wind the steel rope 369.

[0070] When the steel rope 369 is stretched, the second clamping ring 362 is displaced under the connection of the traction seat 368. With the cooperation of the rotating block 366 and the rotating plate 367, the first clamping ring 361 is displaced by the first protruding rod 3611, which in turn makes the first clamping ring 361 and the second clamping ring 362 move closer to each other, thus completing the positioning and clamping of individual materials. In this way, multiple individual materials are simultaneously centered and arranged to ensure that multiple individual materials are evenly distributed, which is beneficial to subsequent cutting and overall removal of finished products.

[0071] Before the gantry 12 and laser cutting head 13 are required to work together for cutting, the two servo motors 23 are controlled to work synchronously, driving the screw 24 to rotate, so that the displacement seat 25 drives the air intake 26 to move down, completing the tight pressing and fixing of the material, which is beneficial to the stable cutting process of the laser cutting head 13 in the future.

[0072] Example 3, referring to Figures 8-9 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0073] Specifically, the transmission assembly 4 includes two protective frames 41, with a movable roller 42 rotatably connected between the two protective frames 41, and a transmission belt 43 sleeved on the movable roller 42.

[0074] The inner ring of the transmission belt 43 is fixed with several evenly distributed helical teeth 431, and the outer ring of the movable roller 42 is provided with a groove 421 that cooperates with the helical teeth 431.

[0075] The top of the protective frame 41 is fixed with a rubber anti-slip pad 411, which not only provides anti-slip function but also has an elastic cushioning function to prevent users from accidentally falling and making hard contact with the protective frame 41 and getting injured.

[0076] In use, driven by an external motor, the movable roller 42 rotates, which in turn causes the transmission belt 43 to rotate continuously for transmission. With the cooperation of the slot 421 and the helical tooth 431, the transmission stability between the movable roller 42 and the transmission belt 43 is improved.

[0077] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
