A laser cutting apparatus with smoke adsorption device

Abstract

This utility model discloses a laser cutting device with a dust adsorption device for use in the field of cutting equipment. Through the follow-up adjustment of the stretchable shield, the dust suction ring holes in the core area directly above the cutting point are fully exposed, the adsorption channel is unobstructed and the suction is stronger, while the dust suction ring holes in the outer area far from the cutting point are still partially covered and the suction is weaker, forming an adsorption gradient with strong center and weak periphery. It can adapt to multi-station processing, which can not only efficiently capture the dust generated by cutting, but also avoid the energy waste caused by ineffective adsorption on the periphery, and achieve a balance between dust collection effect and energy consumption. When the transparent curtain of the dust suction component is lowered, it forms a closed space around the processing area, which can effectively prevent the dust from spreading into the workshop and ensure that the dust is concentrated within the coverage area of ​​the dust suction ring holes. The valve adjustment component can divide the dust suction ring holes of the dust suction follow-up top plate into independent areas according to the work station, which can effectively adapt to multi-station scenarios with multiple laser heads cutting simultaneously.

Description

Technical Field

[0001] This utility model relates to the field of cutting equipment, and in particular to a laser cutting device with a smoke and dust adsorption device. Background Technology

[0002] Laser cutting equipment with fume adsorption devices is a core piece of equipment in the field of laser processing. It is mainly used to solve the problem of fume diffusion generated during laser cutting (metal / non-metal materials). It can prevent fume from blocking the laser beam, which would cause rough cutting surfaces, slag, and other precision problems. It can also reduce the pollution of fume to the health of operators and the workshop environment. It is widely used in sheet metal processing, automotive parts manufacturing, electronic component production and other scenarios.

[0003] Prior art CN218461231U discloses a dust collection device for a laser cutting machine, including a housing with a partition fixedly connected inside and a door movably connected to the front surface of the housing. This structure allows the partition to seal the closed-loop port, facilitating the removal of the dust collection bag and cleaning of the collected waste.

[0004] Existing technology CN219648938U discloses a tracking-equipped laser cutting dust collection device, comprising a laser cutting body, a tracking mechanism, and a dust collection component. The dust collection component includes a filter box mounted on the side of the platform and a dust collection head connected to the filter box via a suction hose. This invention's tracking-equipped laser cutting dust collection device can accurately track the location and quantity of waste and dust generated during laser cutting, avoiding the missed or accidental suction issues present in traditional dust collection equipment.

[0005] With the diversification of laser cutting scenarios, the fixed adsorption structure that is suitable for it cannot meet the flexible follow-up requirements. A single mechanical follow-up structure is difficult to balance dust collection efficiency and energy consumption. The multi-fan, multi-station structure is costly and prone to interference. This application can provide an adsorption adjustment scheme that allows the suction power of the dust collection hole to be flexibly adapted to the cutting point for different cutting scenarios. Utility Model Content

[0006] 1. Technical problems to be solved The core of this invention lies in solving the problem of balancing dust collection efficiency and energy consumption in existing laser cutting equipment by adjusting the stretchable baffle, while providing a flexible and replaceable adsorption adjustment solution.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A laser cutting device with a dust adsorption unit includes a laser cutting assembly. The laser cutting assembly includes a base, with electrically conductive slide rails symmetrically fixedly connected to the upper sides of the left and right ends of the base. A vertical support is slidably connected between the electrically conductive slide rails. An electrically conductive slide rail is fixedly connected to the front end of the vertical support, and a laser cutting head is slidably connected to the front end of the electrically conductive slide rail. A dust collection assembly is fixedly connected to the right side of the vertical support. The dust collection assembly includes a side frame, with a pump fixedly connected to the inner end of the side frame. A dust collection pipe is installed at the input end of the pump. An L-shaped linkage stand is fixedly connected to the upper end of the side frame, and a dust collection follow-up top plate is fixedly connected to the lower end of the L-shaped linkage stand. Multiple dust collection ring holes are opened at the lower end of the dust collection follow-up top plate. A dynamic matching assembly is fixedly connected to the outer side of the laser cutting head. The dynamic matching assembly includes two side connecting frames fixedly connected to the left and right sides of the laser cutting head, respectively. A stretchable cover plate is fixedly connected to the end of the side connecting frame away from the laser cutting head.

[0010] Furthermore, a fixed side strip is fixedly connected to the end of the stretchable shield away from the laser cutting head, and multiple transparent curtains are symmetrically fixedly connected to the front and rear sides of the L-shaped linkage stand.

[0011] Furthermore, a processing table is fixedly connected to the upper end of the base, and the lower ends of multiple transparent curtains that shield the processing table are in contact with each other.

[0012] Furthermore, the multiple suction ring holes are arranged horizontally at equal intervals, and the horizontal end of the suction pipe is interconnected with the multiple suction ring holes through branch pipes.

[0013] Furthermore, the two fixed side strips are fixedly connected to the lower left and right sides of the suction follow-up top plate, and the two stretchable baffles cover half of the suction end of the multiple suction ring holes.

[0014] The further stretchable cover includes multiple strips of protrusions and grooves that slide sequentially onto each other.

[0015] Optionally and preferably, a valve adjustment assembly is fixedly connected to the lower end of the suction follow-up top plate. The valve adjustment assembly includes multiple electric valve blocks, which are respectively installed in the suction end of the corresponding suction ring hole.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are: (1) This solution uses the adjustable stretchable baffle to fully expose the dust collection holes in the core area directly above the cutting point, making the adsorption channel smooth and the suction stronger. The dust collection holes in the outer area far from the cutting point are still partially covered, and the suction is weaker, forming an adsorption gradient with a strong center and a weak periphery. This solution can be adapted to multi-station processing, effectively capturing the dust generated during cutting, while avoiding energy waste caused by ineffective adsorption on the periphery, thus achieving a balance between dust collection effect and energy consumption.

[0018] (2) When the transparent curtain of the dust collection component is lowered, it forms a closed space around the processing area, which can effectively block the spread of smoke and dust to the workshop, ensure that the smoke and dust are concentrated within the coverage area of ​​the dust collection ring hole, greatly improve the efficiency of smoke and dust capture, reduce smoke and dust pollution in the workshop, and improve the working environment of operators.

[0019] (3) The valve adjustment component can divide the dust suction ring holes of the dust suction follow-up top plate into independent areas according to the work position. The electric valve block of each area is independently controlled by the control system, which can avoid mutual interference of the adsorption airflow of different work positions when multiple work positions are cut in a coordinated manner, and effectively adapt to the multi-work position scenario of multiple laser heads cutting simultaneously.

[0022] The technical solution will now be clearly and completely described with reference to the accompanying drawings in the embodiments of this utility model.

[0023] Example 1:

[0024] Please see Figures 1-5 The system includes a laser cutting assembly 1, which includes a base 100. Electrically mounted slide rails 101 are symmetrically fixed to the upper sides of the left and right ends of the base 100. A vertical support 102 is slidably connected between the two slide rails 101. An electrically mounted slide rail 103 is fixedly connected to the front end of the vertical support 102, and a laser cutting head 104 is slidably connected to the front end of the electrically mounted slide rail 103. A dust collection assembly 2 is fixedly connected to the right side of the vertical support 102. The dust collection assembly 2 includes a side frame 200, and a pump is fixedly connected to the inner end of the side frame 200. Model HG-1100 is optional. The vortex air pump has a dust suction pipe 201 installed at the input end of the pump. An L-shaped linkage bracket 202 is fixedly connected to the upper end of the side frame 200. A dust suction follow-up top plate 203 is fixedly connected to the lower end of the L-shaped linkage bracket 202. Multiple dust suction ring holes 204 are opened at the lower end of the dust suction follow-up top plate 203. A dynamic matching component 3 is fixedly connected to the outside of the laser cutting head 104. The dynamic matching component 3 includes two side connecting brackets 302 that are fixedly connected to the left and right sides of the laser cutting head 104 respectively. A stretchable cover plate 301 is fixedly connected to the end of the side connecting bracket 302 away from the laser cutting head 104.

[0025] A fixed side strip 300 is fixedly connected to one end of the stretchable shield 301 away from the laser cutting head 104. Multiple transparent curtains 205 are symmetrically fixedly connected to the front and rear sides of the L-shaped linkage stand 202. A processing table 105 is fixedly connected to the upper end of the base 100. The lower ends of the multiple transparent curtains 205 are in contact with the processing table 105. Multiple dust suction ring holes 204 are horizontally and equidistantly arranged. The horizontal end of the dust suction pipe 201 is connected to the multiple dust suction ring holes 204 through a branch pipe. Two fixed side strips 300 are fixedly connected to the lower left and right sides of the dust suction follow-up top plate 203, respectively. Two stretchable shields 301 cover half of the dust suction end of the multiple dust suction ring holes 204, respectively. The stretchable shield 301 includes multiple protrusion strips 303 and groove strips 304 that slide and fit together in sequence.

[0026] Please see Figures 1-5 In this solution, the thin sheet workpiece is placed on the processing table 105 of the laser cutting assembly 1. According to the cutting path of the part, the vertical support 102 slides horizontally along the first electrical slide rail 101, and the laser cutting head 104 slides up and down along the second electrical slide rail 103, precisely aligning with the area to be cut. The pump of the dust collection assembly 2 is started, and the negative pressure suction is transmitted through the dust collection pipe 201 and branch pipes to the dust collection ring hole 204 of the dust collection follow-up top plate 203, forming a basic suction force. At the same time, the transparent curtains 205 on the front and rear sides of the L-shaped linkage stand 202 hang down, forming a closed space around the processing area to prevent smoke and dust from spreading into the workshop and ensure that the smoke and dust are concentrated within the coverage area of ​​the dust collection ring hole. The laser cutting head 104 is activated. When the laser cutting head moves, the side connecting frames 302 on both sides simultaneously drive the stretchable cover plate 301 of the dynamic matching component 3 to move. The stretchable cover plate is composed of mutually sliding protrusion strips 303 and groove strips 304. It shrinks and stretches as the laser cutting head moves. Since the stretchable cover plate initially covers half of the suction end of the suction ring hole 204, after adjustment, the suction ring hole in the core area directly above the cutting point is fully exposed, the adsorption channel is smoother, and the suction is stronger. The suction ring hole in the outer periphery away from the cutting point is still partially covered, and the suction is weaker. This forms a mechanically adjustable adsorption gradient with strong center and weak periphery, which not only efficiently captures cutting smoke and dust, but also avoids the energy waste of ineffective adsorption on the periphery.

[0027] Example 2:

[0028] Please see Figures 6-7 The lower end of the suction follow-up top plate 203 is fixedly connected to a valve adjustment assembly 4. The valve adjustment assembly 4 includes multiple electric valve blocks 400, the model of which can be selected as VZ300-06-F-M5 mini electric butterfly valve, and is equipped with an electric valve block controller. The multiple electric valve blocks 400 are respectively installed in the suction end of the corresponding suction ring hole 204.

[0029] According to the type of material being cut, the valve adjustment assembly 4 uses the control system to preset the opening parameters of multiple electrical valve blocks 400 in the valve adjustment assembly 4. This divides the dust suction ring hole 204 of the dust suction follow-up top plate 203 into a left workstation area and a right workstation area according to the workstation. The electrical valve block 400 in each area is independently controlled by the control system. The valve adjustment assembly 4 can be used as an optional replacement solution for collaborative cutting scenarios with multiple workstations.

[0030] The above are merely preferred embodiments of this utility model; they encompass all the protection scope of this utility model. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be covered within the protection scope of this utility model.
