Description

Technical Field

[0001] This invention relates to the field of laser cutting equipment technology, specifically to a laser cutting platform cleaning device. Background Technology

[0002] If the welding slag generated during laser cutting on the gear bed is not cleaned in time, it will have serious consequences for many aspects, including equipment precision, processing quality, and production safety: Slag accumulation will accelerate the wear of gear bed transmission components (such as gears and guide rails), leading to decreased transmission precision, workpiece positioning deviation during cutting, and affecting the dimensional accuracy and surface roughness of the gear shape; residual welding slag may get stuck in the movement gaps of the gear bed, causing equipment to stall or even jam, increasing motor load, and causing equipment failure or shutdown; if metal particles in the welding slag adhere to the cutting head or optical components, they will affect laser focusing precision and energy transmission, resulting in reduced cutting efficiency and increased workpiece scrap rate; in addition, long-term accumulation of welding slag may cause open flames due to frictional heat or laser irradiation, posing a fire hazard, especially in flammable environments. Furthermore, unremoved welding slag will occupy the working space of the gear bed, affecting the clamping and positioning of subsequent workpieces, prolonging production preparation time, and reducing overall processing efficiency.

[0003] In the prior art, a device for collecting laser cutting residue, with publication number "CN114043078B", includes a residue-collecting platform installed at the bottom of a laser cutting machine. A pusher assembly is slidably provided at one end of the residue-collecting platform near the laser cutting machine, and a collection hopper is slidably provided at one end along the length of the residue-collecting platform. The opening end of the collection hopper is flush with the collection area of ​​the residue-collecting platform. The pusher assembly includes a pusher component, which includes a pusher head and a movable pusher plate. An elastic element is fixedly provided at the contact part between the pusher head and the movable pusher plate. The movable pusher plate is slidably connected to the end of the pusher head away from the laser cutting machine. This device cleans the residue attached to the residue-collecting platform through the cooperation between the movable pusher plate and the spring component, ensuring stable movement of the pusher head while ensuring complete cleaning of the residue-collecting platform.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] Although the device can collect and clean welding slag, it still does not provide an effective cleaning and removal solution for welding slag on the toothed bed of the cutting platform. In the existing technology, the processing personnel often use a slag remover to clean the welding slag on the toothed bed. This method is not only time-consuming and labor-intensive, but also requires high operational skills from the operators, which is very inconvenient. Summary of the Invention

[0006] The purpose of this invention is to provide a laser cutting platform cleaning device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A laser cutting platform cleaning device includes a support frame, on which a drive chain shaft and a driven chain shaft are rotatably mounted. Support sprockets are fixedly mounted on both the drive and driven chain shafts. A support chain is sleeved between the support sprockets on the drive and driven chain shafts. A plurality of support plates are fixedly mounted on the links of the support chain, and a plurality of support teeth are fixedly mounted on the support plates. The support teeth are perpendicular to the support plates. The position of the support teeth on the support frame can be changed by rotating the support chain.

[0009] A cleaning component for cleaning the support teeth is fixedly installed on one side of the support frame. The cleaning component is linked to the drive chain shaft through a speed change component.

[0010] Preferably, the cleaning assembly includes a cleaning support shaft rotatably mounted on a support frame, a plurality of cleaning frames fixedly mounted on the cleaning support shaft, a cleaning shaft rotatably mounted on each cleaning frame, and a grinding toothed disc fixedly mounted on the cleaning shaft;

[0011] A drive motor is fixedly mounted on the support frame. A cleaning drive pulley is fixedly mounted on the shaft of the drive motor. A cleaning driven pulley is rotatably mounted on the cleaning support shaft. The cleaning drive pulley and the cleaning driven pulley are driven by a cleaning belt. A cleaning drive sprocket is fixedly mounted on one end of the cleaning driven pulley. Both the cleaning driven pulley and the cleaning drive sprocket are rotatably mounted on the cleaning support shaft.

[0012] A cleaning driven sprocket is fixedly installed at one end of the cleaning shaft, and the cleaning drive sprocket and the cleaning driven sprocket are driven by a cleaning chain;

[0013] The support frame is rotatably equipped with several telescopic cylinders. The movable end of the telescopic cylinder is rotatably connected to the cleaning frame. By extending and retracting the telescopic cylinder, the cleaning frame can rotate around the cleaning support shaft.

[0014] Preferably, the transmission assembly includes a clutch gear fixedly mounted on one side of the driven sprocket, a driven gear fixedly mounted at one end of the drive sprocket, and a reduction gear set meshing with the driven gear fixedly mounted on the support frame; a shaft support seat is fixedly mounted on the support frame, a synchronous shaft is rotatably mounted on the shaft support seat, a synchronous gear is fixedly mounted at one end of the synchronous shaft, and the synchronous shaft and the drive sprocket are driven by a pulley set;

[0015] When the clutch gear meshes with the reduction gear set, the reduction gear set drives the driven gear to achieve the rotation of the driving chain shaft;

[0016] When the clutch gear meshes with the synchronizing gear, the synchronizing gear drives the rotation of the drive chain shaft through the pulley set.

[0017] Preferably, a plurality of support rails are fixedly provided on the support frame, and the support rails are used to support the support plate.

[0018] Preferably, a plurality of support sliders are fixedly provided on the support plate, and a plurality of balls are rotatably disposed in the support sliders.

[0019] Preferably, a plurality of support columns are fixedly provided on the support plate, each support column having a threaded hole, and a threaded rod is fixedly provided on the support tooth, the threaded rod being detachably mounted on the support column through the threaded hole.

[0020] Preferably, a protective cover for protection is fixedly installed on the support frame.

[0021] Preferably, the support frame is fixedly provided with a number of height-adjustable support legs.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. The telescopic cylinder drives the clutch gear and the reduction gear set to mesh, forming a reduction transmission path. The drive chain shaft drives the support teeth slowly through the grinding area at a low speed. At this time, the grinding disc rotates at high speed, which can finely grind the impurities on the surface of the support teeth. It is suitable for scenarios that require deep cleaning, such as cleaning and maintenance of support teeth chips, to ensure that the surface condition of the support teeth meets the precision requirements of laser cutting.

[0024] 2. When the telescopic cylinder retracts, the clutch gear meshes with the synchronous gear, achieving high-speed rotation of the drive chain shaft through proportional transmission. The support teeth quickly circulate to the working surface with the chain. In this mode, the grinding disc and the support teeth are separated to avoid interference. This is suitable for rapid replacement of the support position during laser cutting and allows for switching of the support tooth working surface without interrupting operations, thus improving production continuity.

[0025] 3. The automatic switching between "cleaning mode" and "switching mode" can be achieved simply by controlling the extension and retraction of the telescopic cylinder, without the need for manual intervention in the transmission components. This design avoids the cumbersome operation of traditional manual switching, reduces the risk of misoperation, and at the same time, through the automatic switching of the transmission path, the equipment can respond quickly between cleaning and production, adapting to different work rhythms.

[0026] 4. The two modes are switched via the same transmission chain, ensuring thorough cleaning of the support teeth while meeting the need for rapid support position changes during laser cutting operations. The equipment eliminates the need for multiple additional transmission systems, simplifying the structure and achieving integrated "cleaning-production" operation, thus enhancing its practicality and flexibility in actual production.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0036] Please see Figure 1-7 The present invention provides a technical solution:

[0037] The support frame 1 serves as the basic load-bearing structure of the entire device, providing a reference for the installation and support of other components. The drive chain shaft 2 and the driven chain shaft 3 are rotatably connected at both ends of the support frame 1 via bearing seats. This rotatable connection allows the drive chain shaft 2 and the driven chain shaft 3 to rotate freely under the support of the support frame 1.

[0038] Both the driving sprocket 2 and the driven sprocket 3 are fixedly equipped with support sprockets 4, and a support chain 5 is sleeved between the two support sprockets 4, thus forming a chain drive structure. When the driving sprocket 2 rotates under power, it drives the support chain 5 through the support sprockets 4, which in turn drives the driven sprocket 3 to rotate.

[0039] Several support plates 6 are fixedly connected at the links of the support chain 5, and support teeth 7 are vertically arranged on the support plates 6. A support post 601 is fixedly installed on the support plate 6, and the support post 601 has a threaded hole. A threaded rod 701 is fixedly installed on the support tooth 7. When installing the support tooth 7, the threaded rod 701 is screwed into the threaded hole, so that the support tooth 7 can be detachably installed on the support post 601. This structure facilitates the replacement or maintenance of the support tooth 7 in the future.

[0040] When the support chain 5 rotates under the drive of the drive chain shaft 2 and the driven chain shaft 3, the support plate 6 is fixed on the chain link of the support chain 5, so the support plate 6 will move together with the support chain 5, thereby driving the support teeth 7 arranged vertically on the support plate 6 to move synchronously. This realizes the cyclical change of the position of the support teeth 7 on the support frame 1, providing a motion basis for the subsequent cleaning of the support teeth 7 and related operations of the laser cutting platform.

[0041] Example 2:

[0042] On one side of the support frame 1, a cleaning assembly for cleaning the support teeth 7 is provided.

[0043] Its structure consists primarily of a cleaning support shaft 801, which is rotatably mounted on the support frame 1, serving as the basic support shaft for the cleaning assembly. Several cleaning frames 802 are fixedly welded onto this cleaning support shaft 801, and these cleaning frames 802 rotate synchronously with the cleaning support shaft 801.

[0044] A cleaning shaft 803 is rotatably connected to each pair of cleaning frames 802, allowing the cleaning shaft 803 to rotate freely relative to the cleaning frame 802. Several grinding discs 804 are fixed to the cleaning shaft 803. The grinding discs 804 are well-known to those skilled in the art and are commonly used devices in this field, so they will not be described in detail here. The cleaning support shaft 801, cleaning frame 802, cleaning shaft 803, and grinding discs 804 cooperate to form the execution unit for grinding and cleaning the support teeth 7. When the cleaning shaft 803 rotates at high speed, the grinding discs 804 rotate accordingly, providing the power basis for subsequent grinding of the support teeth 7.

[0045] In terms of power supply and transmission, a drive motor 805 is fixedly installed on the support frame 1, serving as the power source. A cleaning drive pulley 806 is fixedly connected to the motor shaft of the drive motor 805. When the motor operates, the motor shaft drives the cleaning drive pulley 806 to rotate. Simultaneously, a cleaning driven pulley 807 is rotatably connected to the cleaning support shaft 801. The cleaning drive pulley 806 and the cleaning driven pulley 807 are connected by a cleaning belt 808. Thus, the power from the drive motor 805 is transmitted to the cleaning driven pulley 807 via the cleaning drive pulley 806 and the cleaning belt 808, causing the cleaning driven pulley 807 to rotate.

[0046] Furthermore, a cleaning drive sprocket 809 is coaxially fixed to one end of the cleaning driven pulley 807. The cleaning drive sprocket 809 and the cleaning driven pulley 807 rotate synchronously, but the cleaning drive sprocket 809 and the cleaning driven pulley 807 as a whole can rotate relative to the cleaning support shaft 801. In addition, a cleaning driven sprocket 8010 is fixedly installed at one end of the cleaning shaft 803. The cleaning drive sprocket 809 and the cleaning driven sprocket 8010 are connected by a cleaning chain 8011. When the cleaning drive sprocket 809 rotates, it drives the cleaning driven sprocket 8010 to rotate through the cleaning chain 8011, which in turn drives the cleaning shaft 803 to rotate. Ultimately, the power of the drive motor 805 is transmitted to the grinding gear disc 804, giving the grinding gear disc 804 the power to rotate and providing conditions for grinding the support teeth 7.

[0047] For the angle adjustment structure, several telescopic cylinders 8012 are rotatably mounted on the support frame 1. The movable end of the telescopic cylinder 8012 is connected to the cleaning frame 802 by a rotatable hinge. When the telescopic cylinder 8012 extends or retracts, since one end is hinged to the support frame 1 and the movable end is hinged to the cleaning frame 802, a thrust or pull force is generated during the length change of the telescopic cylinder 8012, causing the cleaning frame 802 to swing around the cleaning support shaft 801. The swing of the cleaning frame 802 changes the spatial position of the connected cleaning shaft 803 and the grinding toothed disc 804, thereby adjusting the relative position between the grinding toothed disc 804 and the support tooth 7. When it is necessary to grind and clean the support tooth 7, the telescopic cylinder 8012 is extended, causing the grinding toothed disc 804 to approach and contact the support tooth 7; when grinding is not needed, the telescopic cylinder 8012 is reversed, causing the grinding toothed disc 804 to separate from the support tooth 7, thus adapting to different operational needs.

[0048] Through this structural construction and connection, the cleaning component can stably obtain power and flexibly adjust the positional relationship between the grinding toothed disc 804 and the support tooth 7, reliably realizing the grinding and cleaning function of the support tooth 7, and providing strong support for the efficient operation of the entire laser cutting platform cleaning device.

[0049] Example 3:

[0050] During actual operation of the device, the cleaning component and the drive chain 2 are linked by a speed change component. The specific implementation process is as follows:

[0051] like Figure 4 and Figure 5 As shown, when slow grinding and cleaning of the support tooth 7 is required, the telescopic cylinder 8012 is extended. The thrust generated by the extension of the telescopic cylinder 8012 acts on the cleaning frame 802, causing the cleaning frame 802 to swing around the cleaning support shaft 801. As the cleaning frame 802 swings, the clutch gear 901 on the side of the cleaning driven sprocket 8010 gradually approaches and meshes with the reduction gear set 903. The reduction gear set 903 is a set of coaxially fixed gears, including a large gear and a small gear. The large gear meshes with the clutch gear 901 to achieve the first stage of reduction, and the small gear meshes with the driven gear 902 to achieve the second stage of reduction.

[0052] The reduction gear set 903 is engaged with the driven gear 902 at the end of the drive chain shaft 2. At this time, the power output by the drive motor 805 is transmitted along the path of "cleaning component transmission chain (drive motor 805 drives cleaning drive pulley 806, which is transmitted via cleaning belt 808 to cleaning driven pulley 807, and then via cleaning drive sprocket 809 and cleaning chain 8011 to cleaning driven sprocket 8010) → clutch gear 901 → reduction gear set 903 (large gear → shaft → small gear) → driven gear 902". Because the reduction gear set 903 has a reduction function, after the power is transmitted through this gear set, the drive chain shaft 2 will start rotating at a lower speed.

[0053] When the drive chain 2 rotates, it drives the cooperating support chain 5, which in turn drives the support plate 6 to move slowly. As the support plate 6 moves, the support teeth 7 mounted on the support plate 6 pass one by one over the grinding disc 804 (during the entire process, the grinding disc 804 is continuously powered by the cleaning component's drive chain and remains in a rotating state). The rotating grinding disc 804 contacts the passing support teeth 7, performing a grinding and cleaning operation on the support teeth 7. The support chain 5 continues to rotate in a cycle, allowing the support teeth 7 to continuously enter the grinding area, thus achieving a continuous, slow grinding operation for the support teeth 7 and ensuring that each support tooth 7 is thoroughly ground and cleaned.

[0054] like Figure 6 and Figure 7 As shown, when it is necessary to quickly switch the support tooth 7 to the working surface, the telescopic cylinder 8012 is retracted. The pulling force generated by the retraction of the telescopic cylinder 8012 will pull the cleaning frame 802 to swing in the opposite direction. During this swinging process, the clutch gear 901 disengages from the reduction gear set 903 and instead engages with the synchronous gear 906.

[0055] Synchronous gear 906 is mounted on synchronous shaft 905, which is rotatably mounted on support frame 1 via shaft support seat 904, providing a stable mounting and rotational foundation for synchronous gear 906. Synchronous shaft 905 and drive chain shaft 2 are connected via pulley set 907 with a transmission ratio of 1:1. At this time, the power output from drive motor 805 is still first transmitted to clutch gear 901 via the cleaning component transmission chain, and then the power transmission path becomes "clutch gear 901 → synchronous gear 906 → synchronous shaft 905 → pulley set 907 → drive chain shaft 2". Because synchronous gear 906 and pulley set 907 are both proportional transmissions (transmission ratio 1:1), the speed does not change during power transmission, so drive chain shaft 2 rotates rapidly.

[0056] When the drive chain 2 rotates rapidly, it drives the support chain 5 to move rapidly, which in turn drives the support plate 6 to move rapidly as well. Simultaneously, due to the reverse oscillation of the cleaning frame 802, the grinding toothed disc 804 separates from the support tooth 7, avoiding unnecessary interference during the rapid movement of the support tooth 7. In this way, the support tooth 7 can quickly switch to the working surface, meeting the needs of scenarios requiring rapid changes to the working surface support tooth 7 and improving the adaptability of the device to different work rhythms.

[0057] By switching between these two transmission paths, the telescopic cylinder 8012 controls the meshing of the clutch gear 901. Combined with the characteristics of different transmission components, the device can flexibly realize the two functions of "slow grinding and cleaning" and "fast gear position switching", ensuring that the cleaning operation of the laser cutting platform is carried out efficiently and in an orderly manner.

[0058] Example 4:

[0059] During the device assembly phase, support rails 10 are installed at corresponding positions on support frame 1 using reliable fixing methods (such as welding, bolting, etc.) to serve as guide references for the movement of support plate 6. At the bottom of support plate 6, a dedicated support slider 11 is provided, and ball bearings (not shown in the figure, representing mature existing technology) are rotatably embedded in the internal space of the support slider 11.

[0060] When the device is running, and the support chain 5 drives the support plate 6 to move, the support slider 11 at the bottom of the support plate 6 will slide against the support guide rail 10 on the support frame 1. At this time, the balls rotate within the support slider 11, transforming the sliding friction between the support slider 11 and the support guide rail 10 into rolling friction of the balls. This change in friction greatly reduces the frictional resistance experienced by the support plate 6 during its movement, allowing the support plate 6 to move more smoothly with the support chain 5. Simultaneously, the support guide rail 10 provides precise guidance for the movement of the support plate 6, ensuring the stability of the movement trajectory of the support plate 6 and its support teeth 7, and preventing movement deviations from affecting the cleaning effect of the support teeth 7 and the overall operational reliability of the device.

[0061] After the installation and debugging of all transmission components (chains, sprockets, gears, etc.) are completed, the protective cover 12 is assembled onto the support frame 1 using a suitable installation method (such as bolt connection, snap-fit ​​connection, etc.), so that the protective cover 12 covers the transmission components such as chains, sprockets, and gears. In this way, it can prevent workers from accidentally coming into contact with the moving transmission components, providing good protection and ensuring the stable operation of the device and the safety of personnel operation.

[0062] At the bottom of the support frame 1, adjustable support feet 13 are installed. During installation, the support feet 13 are connected to the bottom of the support frame 1. When the device needs to be leveled, the support height of the support feet 13 is changed by operating the adjustment mechanism of the support feet 13. Adjusting the height of each support foot 13 according to different installation sites or operational requirements ensures that the entire support frame 1 is level, guaranteeing the stability of the device's operation. Simultaneously, adjusting the height of the support feet 13 allows the device to adapt to different operating height requirements, improving its applicability in various application scenarios.

[0063] Working principle: During use, the driving sprocket 2 rotates under external power, driving the supporting sprocket 4 on it to rotate. The supporting sprocket 4 drives the driven sprocket 3 to rotate synchronously through the supporting chain 5, forming a closed-loop transmission.

[0064] The support plate 6 fixed on the link of the support chain 5 moves cyclically with the chain, and the support tooth 7 vertically installed on the support plate 6 moves in a cyclic trajectory above the support frame 1, thereby realizing the switching of the position of the support tooth 7 on the working surface.

[0065] When it is necessary to clean the support tooth 7, the telescopic cylinder 8012 is extended, pushing the cleaning frame 802 to swing around the cleaning support shaft 801, causing the clutch gear 901 on the side of the driven sprocket 8010 to mesh with the reduction gear set 903. The reduction gear set 903 consists of a large gear and a small gear. The large gear meshes with the clutch gear 901, and the small gear meshes with the driven gear 902 at the end of the drive sprocket 2, forming a two-stage reduction.

[0066] The power from the drive motor 805 is transmitted to the drive sprocket 2 via the following steps: "cleaning the drive pulley 806 → cleaning the belt 808 → cleaning the driven pulley 807 → cleaning the drive sprocket 809 → cleaning the chain 8011 → cleaning the driven sprocket 8010 → clutch gear 901 → reduction gear set 903 → driven gear 902". Due to the reduction effect of the reduction gear set 903, the drive sprocket 2 rotates at a low speed, driving the support chain 5 and the support plate 6 to move slowly.

[0067] Meanwhile, the drive motor 805 drives the grinding disc 804 to rotate at high speed through the cleaning component transmission chain. When the slowly moving support tooth 7 passes the grinding disc 804, the high-speed rotating grinding disc 804 grinds and cleans the welding slag on the surface of the support tooth 7. The support chain 5 rotates in a cycle so that each support tooth 7 passes through the cleaning area in turn, achieving continuous slow grinding.

[0068] When it is necessary to quickly change the working surface support gear 7, the telescopic cylinder 8012 is retracted, pulling the cleaning frame 802 to swing in the opposite direction. The clutch gear 901 disengages from the reduction gear set 903 and instead meshes with the synchronous gear 906. The synchronous gear 906 is connected to the pulley set 907 (transmission ratio 1:1) between the synchronous shaft 905 and the drive chain shaft 2.

[0069] The power of the drive motor 805 is transmitted through "clutch gear 901 → synchronous gear 906 → synchronous shaft 905 → pulley set 907 → drive chain shaft 2". Since the synchronous gear 906 and the pulley set 907 are both proportional transmissions, the drive chain shaft 2 rotates at high speed, driving the support chain 5 and the support plate 6 to move quickly.

[0070] When the cleaning frame 802 swings in the opposite direction, the grinding toothed disc 804 moves away from the support tooth 7 along with the cleaning frame 802, avoiding interference during high-speed movement. At this time, the support tooth 7 quickly cycles to the working surface, meeting the need for rapid switching of support position in laser cutting operations.

[0071] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
