Description

Technical Field

[0001] This utility model relates to the field of laser cutting, specifically to a feeding mechanism for a laser cutting machine. Background Technology

[0002] A laser cutting machine is a CNC device that uses a high-energy laser beam to precisely cut materials. By focusing the laser beam onto the material surface, it rapidly melts, vaporizes, or ablates the material. Assisted gases (such as oxygen or nitrogen) are used to remove the molten slag, achieving high-precision and high-efficiency cutting. The feeding mechanism of the laser cutting machine is a key component of the automated production system, primarily used to efficiently and accurately transport raw materials (such as metal sheets) to the cutting area. Existing technologies have the following problems:

[0003] 1. Most existing feeding mechanisms use conveyor belts to transport sheet materials. The sheet materials are usually stored and transported in the open air, and impurities on the sheet materials will adhere to the conveyor belt. The accumulation of impurities on the conveyor belt will affect the feeding.

[0004] 2. There is often a gap between the feeding mechanism and the worktable of the laser cutting machine. When feeding some thinner plates, the ends of the plates may bend downwards due to insufficient hardness, thus getting stuck between the conveyor belt and the worktable. This requires manual adjustment, which increases the labor intensity.

[0005] Therefore, a feeding mechanism for laser cutting machines is proposed, which can automatically clean the surface of the conveyor belt and stably transport thin sheet materials to the worktable of the laser cutting machine, thereby improving production efficiency. Utility Model Content

[0008] Preferably, at least one first electric lifting rod is provided on the side of the conveyor belt, and a support rod is fixedly connected to the top of the first electric lifting rod.

[0009] Preferably, a base is provided below the support frame, and the base and the support frame are connected by four rectangularly distributed second electric lifting rods to form a height-adjustable structure.

[0010] Preferably, the bottom of the base is equipped with casters with brakes.

[0015] Beneficial effects

[0016] (1) The cleaning roller in this utility model can clean the conveyor belt and prevent excessive impurities from adhering to the conveyor belt, thus affecting the conveying effect.

[0017] (2) In this utility model, by setting a liftable support rod on one side of the conveyor belt, when conveying soft thin plates, the support rod can be raised so that it is supported between the conveyor belt and the worktable of the laser cutting machine, thus preventing one end of the plate from sinking and getting stuck on the worktable, ensuring normal feeding and improving production efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In the description of this utility model, it should be understood that the terms "middle", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] like Figure 1-2 As shown, a feeding mechanism for a laser cutting machine includes a support frame 1, a conveyor belt 2 on the support frame, and a cleaning mechanism below the conveyor belt. The cleaning mechanism includes two symmetrically arranged mounting frames 3, each mounting frame having a cleaning roller 4 rotatably connected to it. The surface of the cleaning roller is covered with cleaning bristles that abut against the lower surface of the conveyor belt. One end of the cleaning roller is driven to a cleaning motor 401. The two cleaning rollers are linked by a synchronous belt 402, which moves in the opposite direction to the conveyor belt, so that the cleaning roller can better clean the lower surface of the conveyor belt when it abuts against it.

[0024] At least one first electric lifting rod 5 is provided on the side of the conveyor belt. A support rod 6 is fixedly connected to the top of the first electric lifting rod. When the conveyor belt is conveying thin sheet material, the first electric lifting rod drives the support rod to rise, so that the upper surface of the support rod is at the same level as the conveyor belt. The thin sheet material moves from the conveyor belt to above the support rod, and then moves to the worktable of the laser cutting machine. With the support of the support rod, the end of the thin sheet material will not sink, which can maintain the normal conveying of the sheet material, avoid manual adjustment of the sheet material, and reduce the labor intensity of the operator.

[0025] A base 7 is provided below the support frame. The base and the support frame are connected by four rectangularly distributed second electric lifting rods 8 to form a height-adjustable structure. When the four electric lifting rods are activated simultaneously, they can drive the support frame to move up and down, thereby adjusting the height of the conveyor belt on the support frame. This adapts to laser cutting machines of different heights and improves the applicability of the device. The bottom of the base is equipped with casters 9 with brakes. The casters facilitate the movement of the base and make it easy to move the device flexibly to meet different production needs.

[0026] The support frame has a built-in dust collection box 10, located below the two cleaning rollers. The middle part of the support frame is hollow, and the dust collection box is embedded in the hollow structure. Impurities cleaned by the cleaning rollers can fall into the dust collection box, avoiding secondary pollution. The bottom of the dust collection box has a suction port, which is connected to a negative pressure generator 12 via a hose. A filter screen 11 is installed at the suction port. While the cleaning rollers clean the conveyor belt, the negative pressure generator is activated, and the suction port collects the impurities falling into the dust collection box and draws them onto the filter screen for easy cleaning by the operator.

[0027] The conveyor belt includes conveyor frames 201 symmetrically arranged on both sides of the support frame. Each conveyor frame is rotatably connected to a conveyor roller 202. A conveyor belt 203 is installed over the two conveyor rollers. One of the conveyor rollers is driven by a conveyor motor 204. A baffle 14 is fixedly connected between the conveyor frames on the same side. The baffle limits the material during the conveying process to ensure the normal conveying of the material.

[0028] The base is equipped with an energy storage battery 13, which is used to provide power to the conveyor motor, the cleaning motor, the first electric lifting rod, the second electric lifting rod, and the negative pressure generator.

[0029] Working principle

[0030] When using this device, the sheet material moves on the conveyor belt 2. When there are impurities on the conveyor belt that need to be cleaned, the cleaning motor 401 is started. The cleaning motor drives two cleaning rollers 4 to rotate via a synchronous belt. The bristles wrapped on the cleaning rollers come into contact with the lower surface of the conveyor belt, thereby cleaning the impurities on the conveyor belt. The cleaned impurities fall into the dust collection box 10. The negative pressure generator 12 is started to adsorb the impurities in the dust collection box, thereby concentrating the impurities onto the filter screen 11 for easy cleaning later. When the conveyor belt is conveying thin sheet material, the first electric lifting rod 5 is started. The first electric lifting rod drives the support rod 6 to move upward, so that the upper end of the support rod is at the same level as the upper surface of the conveyor belt. The thin sheet material can move from the conveyor belt to the support rod and then to the worktable of the laser cutting machine. With the support rod in the middle, it can effectively prevent one end of the sheet material from sinking and getting stuck between the worktable and the conveyor belt, avoiding manual adjustment, reducing the labor intensity of the operators, and improving production efficiency.

[0031] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
