Description

Technical Field

[0001] This utility model relates to the field of laser paint stripping machines, and in particular to a negative pressure collection structure for residues in laser paint stripping machines. Background Technology

[0002] In practical applications of laser paint stripping machines, effectively handling the residue generated during the paint stripping process has always been a critical issue that the industry urgently needs to address. Traditional laser paint stripping machines often employ relatively simple collection methods for residue, or use some conventional equipment to collect the residue.

[0003] Although some of these devices are equipped with simple dust collection devices, they are mostly fixed, integrated structures. The filters, which are mainly responsible for filtration, are usually fixed inside the collection box. Cleaning requires operators to disassemble a large number of parts so that the filters can be removed before cleaning and maintenance can be performed. The overall operation is cumbersome and time-consuming. This not only prolongs the equipment downtime for maintenance and reduces production efficiency, but also requires high professional skills from operators, increasing labor costs.

[0004] Therefore, it is necessary to provide a new negative pressure collection structure for the residue of a laser paint stripper to solve the above-mentioned technical problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a negative pressure collection structure for residues in a laser paint stripping machine.

[0006] This utility model provides a negative pressure collection structure for residues from a laser paint stripper, comprising: a base, a support frame fixedly connected to the base, a laser assembly mounted on the support frame, a negative pressure suction shell located at the center of the base, a processing box fixedly connected to the other end of the base, a negative pressure fan mounted on the upper shell wall of the processing box, the air inlet of the negative pressure fan connected to the upper shell wall of the processing box, a connecting pipe fixedly connected to the negative pressure suction shell, the other end of the connecting pipe connected to the side wall of the processing box, and a filter frame located inside the processing box; and a convenient cleaning mechanism, comprising an external frame fixedly connected to the side wall of the processing box, two fixed rods symmetrically fixedly connected to the external frame, a combined frame slidably connected between the two fixed rods, the filter frame located within the combined frame, and a locking assembly between the combined frame and the external frame.

[0007] Preferably, the side wall of the processing box is provided with a through opening, the combined frame is slidably connected to the through opening, both of the fixing rods are inserted into the through opening, and the other ends of both fixing rods are connected to the inner wall of the processing box.

[0008] Preferably, the locking assembly includes a strip-shaped shell, which is fixedly installed on the side wall of the processing box. An internal shaft is rotatably connected in the strip-shaped shell. Alignment clips are symmetrically provided at both ends of the internal shaft, and a turntable is installed and connected to one end of the internal shaft.

[0009] Preferably, the strip shell has limiting openings at both ends, and the two alignment clips are slidably connected to the two ends of the limiting openings respectively. The two side walls of the outer frame are provided with sliding openings, and the upper ends of the two alignment clips are slidably connected to the two sliding openings respectively.

[0010] Preferably, the two ends of the built-in shaft are provided with threads in opposite directions, and the lower ends of the two alignment clips are provided with threaded openings, and the lower ends of the two alignment clips are respectively threaded to the two ends of the built-in shaft.

[0011] Preferably, two strip baffles are symmetrically arranged on the inner sidewall of the combination frame, and multiple limiting posts are provided on each of the two strip baffles. Multiple mounting ports are provided on the filter frame, and the multiple limiting posts are slidably connected to the multiple mounting ports respectively. Multiple pressure plates are fixedly connected to the inner wall of the processing box, and the multiple pressure plates are all located above the filter frame.

[0012] Compared with related technologies, the negative pressure collection structure for residues in a laser paint stripper provided by this utility model has the following advantages:

[0013] This utility model greatly simplifies the cleaning process of the filter screen frame by using the combination of the combined frame and the fixed rod. In practical applications, the operator only needs to pull out the combined frame and let it slide relative to the two fixed rods to automatically remove the filter screen frame, which greatly shortens the equipment maintenance time, reduces the downtime caused by cleaning the filter screen frame, significantly improves the actual usage time of the laser paint stripping machine, and enables the equipment to be put into production operations more efficiently, bringing higher production benefits to enterprises.

[0014] 2. This utility model uses a built-in shaft and a threaded connection with the alignment clips, so that rotating the turntable can drive the two alignment clips to slide in the opposite direction along the limiting holes at both ends of the strip shell until they disengage from the sliding holes on both sides of the outer frame, thereby controlling the locking of the combination frame. This allows the combination frame to be pulled out directly along the fixing rod, which not only facilitates the cleaning of the filter frame, but also ensures that the filter frame and the combination frame can be stably placed inside the processing box during normal operation, ensuring stable collection of residues.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figures 1 to 4 A negative pressure collection structure for residues of a laser paint stripper includes: a base 1, a support frame 2 fixedly connected to the base 1, a laser component 21 mounted on the support frame 2, a negative pressure suction shell 3 located in the middle of the base 1, a processing box 4 fixedly connected to the other end of the base 1, a negative pressure fan 41 mounted on the upper shell wall of the processing box 4, the air inlet of the negative pressure fan 41 connected to the upper box wall of the processing box 4, a connecting pipe 42 fixedly connected to the negative pressure suction shell 3, the other end of the connecting pipe 42 connected to the side wall of the processing box 4, and a filter frame 43 located inside the processing box 4; and a convenient cleaning mechanism including an external frame 5 fixedly connected to the side wall of the processing box 4, two fixed rods 51 symmetrically fixedly connected in the external frame 5, a combined frame 52 slidably connected between the two fixed rods 51, the filter frame 43 located in the combined frame 52, and a locking component between the combined frame 52 and the external frame 5.

[0022] In the specific implementation process, such as Figure 1 and Figure 2 As shown, a through opening is provided on the side wall of the processing box 4. The combination frame 52 is slidably connected to the through opening. Two fixing rods 51 are inserted into the through opening, and the other ends of the two fixing rods 51 are connected to the inner wall of the processing box 4.

[0023] It should be noted that the sliding fit between the through-hole and the combination frame 52, as well as the design of the fixing rod 51 passing through it and connecting to the inner wall of the processing box 4, provides a precise sliding track for the combination frame 52, ensuring that it will not shift or shake during the extraction and installation process.

[0024] The combination frame 52 and the fixing rod 51 ensure that the filter frame 43 can smoothly enter and exit the processing box 4 for cleaning, and the filter frame 43 can be taken out of the processing box 4 along with the combination frame 52 for cleaning.

[0025] refer to Figure 2 and Figure 4 As shown, the locking assembly includes a strip-shaped shell 6, which is fixedly installed on the side wall of the processing box 4. An internal shaft 61 is rotatably connected in the strip-shaped shell 6. Alignment clips 62 are symmetrically provided at both ends of the internal shaft 61. A turntable 63 is installed and connected to one end of the internal shaft 61.

[0026] It should be noted that: by rotating the turntable 63 to control the rotation of the built-in shaft 61, which in turn drives the alignment clamp 62 to move, it is simpler and more efficient than the traditional complex and difficult-to-operate locking device, greatly improving the convenience of equipment maintenance.

[0027] refer to Figure 4 As shown, both ends of the strip shell 6 are provided with limiting ports, and the two alignment clips 62 are slidably connected to the two ends of the limiting ports respectively. The two side walls of the outer frame 5 are provided with sliding openings, and the upper ends of the two alignment clips 62 are slidably connected to the two sliding openings respectively.

[0028] It should be noted that the sliding connection between the limiting port and the alignment piece 62 precisely limits the movement trajectory of the alignment piece 62.

[0029] Meanwhile, the cooperation between the sliding opening of the external frame 5 and the upper end of the alignment clip 62 ensures that the combination frame 52 can be firmly fixed on the external frame 5 in the locked state, thus ensuring the stable placement of the filter frame 43 inside the processing box 4.

[0030] refer to Figure 2 and Figure 4 As shown, the two ends of the built-in shaft 61 are provided with threads in opposite directions, and the lower ends of the two alignment clips 62 are provided with threaded openings. The lower ends of the two alignment clips 62 are respectively threaded to the two ends of the built-in shaft 61.

[0031] It should be noted that the engagement of the threads at both ends of the built-in shaft 61 with the threaded opening at the lower end of the alignment clip 62 utilizes the principle of thread transmission. This enables the two alignment clips 62 to slide synchronously and in opposite directions when the turntable 63 is rotated. With just one rotation, the movement of the two alignment clips 62 can be controlled simultaneously. Furthermore, the threaded connection has excellent self-locking performance, providing sufficient tightening force when locking the combination frame 52 to prevent the combination frame 52 from accidentally loosening.

[0032] refer to Figure 1 and Figure 2As shown, two strip baffles 7 are symmetrically arranged on the inner side wall of the combination frame 52. Each strip baffle 7 is provided with multiple limiting posts 71. The filter frame 43 is provided with multiple installation ports. The multiple limiting posts 71 are slidably connected to the multiple installation ports respectively. Multiple pressure strips 8 are fixedly connected to the inner wall of the treatment box 4. The multiple pressure strips 8 are all located above the filter frame 43.

[0033] It should be noted that the sliding connection between the limiting post 71 on the inner sidewall strip baffle 7 of the combination frame 52 and the installation port of the filter frame 43 plays a role in precise positioning when installing the filter frame 43, making it convenient for operators to quickly and accurately install the filter frame 43 into the combination frame 52.

[0034] After the filter frame 43 is installed in place, the pressure strip 8 on the inner wall of the treatment box 4 presses the filter frame 43 from above, further enhancing the stability of the filter frame 43 during operation, preventing it from shifting due to the impact of negative pressure airflow, and ensuring the stability of the residue filtration effect.

[0035] The working principle of the negative pressure collection structure for the residue of a laser paint stripping machine provided by this utility model is as follows: When the laser paint stripping machine is operating, the laser component 21 performs paint stripping operation on the workpiece under the support of the stand 2. During this process, paint residue, dust and other residues will be scattered. At this time, the negative pressure suction shell 3 in the middle of the base 1 plays a role. After the negative pressure fan 41 is started, a negative pressure environment is formed in the processing box 4. The negative pressure is transmitted to the negative pressure suction shell 3 through the connecting pipe 42, so that the negative pressure suction shell 3 can suck the surrounding residue into the connecting pipe 42 and introduce it into the processing box 4. The residue entering the processing box 4 will be intercepted and filtered by the internal filter frame 43, and the purified air will be discharged from the negative pressure fan 41.

[0036] When the filter frame 43 needs to be cleaned, rotate the turntable 63. The two alignment clips 62 slide in the opposite direction along the limiting ports at both ends of the strip shell 6 under the action of the threads until they disengage from the sliding ports on both sides of the outer frame 5. At this time, the locking of the combination frame 52 is released, so the combination frame 52 can be pulled out along the fixing rod 51. The filter frame 43 is then taken out of the processing box 4 along with the combination frame 52. This makes it easy to directly separate the filter frame 43 from the combination frame 52 for cleaning, which is very quick and convenient.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
