Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting table rack cleaning applications, in particular to a laser cutting table rack cleaning device. Background Art

[0002] The cutting table of a laser cutting machine is generally composed of multiple rows of racks, and the material to be cut is supported by a rack support plate. When laser cutting, that is, when the material is laser cut, the material needs to be melted. The molten iron will drip onto the rack support plate and solidify on the rack support plate. After long-term use, a large amount of iron slag will accumulate on the rack support plate. The accumulation of these iron slags will cause the levelness of the entire cutting table to decrease, thereby affecting the fineness of the cutting.

[0003] To solve this problem, the traditional method is to cut off the rack support plate and replace it with a new one. This method is not only inefficient but also results in a serious waste of resources. To solve this problem, various improvements have been proposed, but their principles are all based on the principle of crushing (such as the "Laser Cutting Table Rack Cleaning Method" published by the State Intellectual Property Office under Publication No. CN113290318A), which uses a tool to crush the iron slag to achieve the purpose of cleaning.

[0004] While the above solution can achieve the cleaning purpose, the iron slag is molten iron stuck to the rack support plate, and its essence is still steel. This hard-hitting cleaning method easily causes wear, which reduces the tool life and increases the cost of use. Furthermore, if the tool gets stuck, it can easily cause the drive motor to burn out. Therefore, how to clean the iron slag cost-effectively and efficiently is currently a problem that needs to be solved. Utility Model Content

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figures 1 to 4 As shown, this embodiment aims to provide a method for quickly and cleanly removing iron slag from the rack support plate while reducing or eliminating the loss of parts, thereby achieving the purpose of zero-cost iron slag cleaning. To this end, in order to achieve the above-mentioned purpose, the laser cutting table rack cleaning device provided in this embodiment includes a frame 1 for placement on the laser cutting table and a cleaning mechanism disposed within the frame 1, with the cleaning mechanism being arranged to move on the frame 1. In this embodiment, the frame 1 is arranged in the shape of a rectangular frame, which has two purposes: one is to limit the moving direction of the cleaning mechanism, and the other is to rely on its gravity to provide stability for the movement of the cleaning mechanism.

[0024] To clean the rack support plate, the cleaning mechanism includes a traveling frame 2 and a cleaning claw 3 mounted on the traveling frame 2. The main purpose of the traveling frame 2 is to accommodate equipment such as the cleaning claw 3 and to enable travel on the frame 1. In this embodiment, the traveling frame 2 includes a double-layer plate and connecting blocks on both sides of the double-layer plate. The connecting blocks are primarily used to connect to a drive chain 22. A traveling motor is provided on the frame 1, and the drive chain 22 is connected to the traveling motor. Travel wheels 12 are provided at the end of the connecting blocks away from the double-layer plate. The travel wheels 12 are mounted on the bottom beam of the frame 1. In this embodiment, to prevent the lower-layer travel wheels 12 from moving up and down, a layer of auxiliary beams is provided on the frame 1. The auxiliary beams are spaced apart from the bottom beams, and the lower-layer travel wheels 12 are positioned within the space between them. This creates a position limit for the traveling frame 2 and also enables the frame 1 to provide stability for the traveling frame 2. Because the connecting blocks are connected to the drive chain 22, the traveling frame 2 can move forward and backward when the traveling motor rotates forward and reverse. In this embodiment, to ensure travel stability, two crossbars are connected at the top of the traveling frame 2 via a chain. Travel wheels 12 on the upper layer of the traveling frame 2 are provided at both ends of the crossbars. The upper layer of the traveling wheels 12 rests on the upper beams of the frame 1, ensuring travel stability. Of course, other methods can also be used to drive the traveling frame 2. For example, a motor can be provided on the traveling frame 2 and a rack can be provided on the frame 1, and travel can also be achieved through the cooperation of the gear and rack. Long-stroke pneumatic or hydraulic cylinders can also be used, but cylinders and hydraulic cylinders require other supporting equipment, and the structure of the motor and rack requires the provision of tracks and sliders. The method of using a motor in conjunction with the drive chain 22 offers the best cost and stability.

[0025] Taking into account the traditional cleaning method is hard-hitting crushing, this cleaning method causes immeasurable damage to the tool. At the same time, considering that the iron slag is melted and bonded to the rack support plate, although it is integrated, it is not fixed so firmly. Then, the principle of the lever is to cleverly use the form of a fulcrum to generate a large prying force, thereby lifting the object, and the rack support plate is welded to the cutting table. Then, with the help of the fixed rack support plate, the iron slag can be pried up to achieve separation. For this purpose, the cleaning pry claw 3 can be flipped and set on the walking frame 2. Of course, the flipping setting of the cleaning pry claw 3 is based on the fulcrum for flipping, and the flipping here is only a small angle flip, which is enough to pry off the iron slag.

[0026] To ensure the flipping of the cleaning claw 3, a power mechanism for controlling the reciprocating prying of the cleaning claw 3 is also provided on the walking frame 2. The cleaning claw 3 includes a prying head 31 and a slot 32 disposed at the end of the prying head 31. The prying head 31 is generally rectangular in shape. In this embodiment, to ensure strength, the top surface of the prying head 31 is inclined, which facilitates increasing the thickness at the fulcrum and ensuring the stability of the connection. The main purpose of the slot 32 is to insert the prying head 31 into the rack support plate so that the end of the prying head 31 is below the iron slag. In this way, the cleaning claw 3, through the slot 32, places the prying head 31 on both sides of the rack, and then pries the iron slag on the rack from bottom to top, thereby removing the iron slag from the rack.

[0027] There are two ways to place the fulcrum. The first is to set a fulcrum below the cleaning pry claw 3. In this way, prying is achieved by pressing the other end of the pry head 31 away from the slot 32. The other is to set a separate pressing point. In this embodiment, the second method is adopted. Specifically, a rotating shaft 51 is set at the end of the pry head 31 away from the slot 32. The pry head 31 is fixed to the rotating shaft 51 by welding in this embodiment. This is because the pry head 31 has minimal wear and can be used for a long time, and the welding method is more stable. The power mechanism controls the reciprocating prying of the cleaning pry claw 3 by controlling the rotating shaft 51. There are two ways to control the rotating shaft 51. One is to directly connect the rotating shaft 51, which requires strong torque. The other is to set a plate on the side of the rotating shaft 51 away from the pry head 31.

[0028] The power mechanism is an air cylinder or an oil cylinder. At this time, a plate is set on the side of the rotating shaft 51 away from the prying head 31, and the power end of the air cylinder or the oil cylinder can be used to press the plate. Considering that the prying head 31 needs to be tilted, the reciprocating motion of the air cylinder and the oil cylinder is relatively slow at this time. For this reason, in this embodiment, the power mechanism is a drive motor 4 and an eccentric wheel 41 provided with the power end of the drive motor 4, and the eccentric wheel 41 is in contact with the rotating shaft 51. Specifically, a square connecting frame 5 is sleeved on the outside of the eccentric wheel 41, and one corner of the connecting frame 5 is welded to the side of the rotating shaft 51 away from the prying head 31. The connecting frame 5 is in contact with the eccentric wheel 41. In this way, under the rotation of the eccentric wheel 41, the connecting frame 5 is driven to shake rapidly, thereby driving the prying head 31 to flip back and forth rapidly.

[0029] In this way, under the action of the driving motor 4, the cleaning claw 3 is quickly flipped back and forth. At the same time, the walking frame 2 walks on the frame 1, and the cleaning of a rack can be completed quickly. In the cleaning process, the frame 1 also provides stability to the cleaning claw 3 to ensure its force application.

[0030] Since the cleaning claws 3 can only clean one rack at a time (of course, multiple cleaning claws can also be welded to one end of the rotating shaft), and since the laser cutting tables vary in size, the frame 1 still needs to be moved. To this end, the frame 1 is arranged to be movable on the laser cutting table. Since the frame 1 also plays a stabilizing role, its wheels cannot be in contact with the cutting table for a long time. Therefore, screw lifts 11 are provided at the corners of the frame 1, and running wheels 12 are provided at the bottom of the screw lifts 11. The frame 1 can be arranged to be movable on the laser cutting table through the screw lifts 11 and the running wheels 12.

[0031] Through the above-mentioned setting, the principle of lever is cleverly utilized to pry the iron slag from the rack, which not only does not damage the tool, but also has a fast cleaning speed and good cleaning efficiency, and is suitable for large-scale promotion and use.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
