Abstract
Description
Technical Field
[0001] This utility model relates to the field of air purification equipment manufacturing, and in particular to a folding mesh unit forming device. Background Technology
[0002] Air filters are the most commonly used components in air purification. They generally consist of a frame and a mesh fabric mounted on the frame. The mesh fabric is typically pleated to increase the filtration area. The pleated mesh is cut and then glued to the frame. Currently, there are two main methods for cutting pleated mesh units:
[0003] The first method involves manually counting the number of tooth peaks on the folded mesh according to the set requirements, and then cutting the folded mesh. This method requires workers to count and cut manually, which is prone to human error, inefficient, and makes it difficult to guarantee the accuracy and consistency of the cutting.
[0004] The second method uses a template for producing folded mesh, with toothed grooves covering the entire upper surface of the base plate. When installing the folded mesh onto this template, each crest and trough of the folded mesh must align with the toothed grooves on the template. This method has the following problems: First, the installation process is relatively cumbersome; misalignment of even one tooth often leads to misalignment of the entire folded mesh with its template. Second, the template is relatively large, requiring the entire folded mesh to be unfolded, thus occupying a significant area. Finally, because each tooth needs to be aligned individually, the cutting time is long.
[0005] Both methods have significant drawbacks. Manual cutting is inefficient, error-prone, and unsuitable for large-scale production. While using templates is relatively automated, the installation process is complex, prone to misalignment, and requires significant space, resulting in low cutting efficiency. These problems severely restrict the production efficiency and quality of folded mesh units. Furthermore, existing cutting methods struggle to achieve precise control and automated production. In actual production, different filter sizes may require folded mesh units of varying lengths, and existing methods cannot quickly and flexibly adjust the cutting length. Simultaneously, the lack of effective counting and control mechanisms makes it difficult to guarantee the consistency of each folded mesh unit, potentially leading to problems during subsequent assembly and affecting the quality of the final product. Summary of the Invention
[0006] To address the aforementioned problems, the purpose of this invention is to provide a folded mesh unit forming device, which has the advantages of improving the production efficiency of folded mesh units, ensuring cutting accuracy and consistency, and realizing automated production.

[0009] Furthermore, this application also proposes that a laser cutting head is movably disposed in the laser cutting machine, and the laser cutting head is disposed along the length direction of the rack on the traction conveyor belt.
[0010] Furthermore, this application also proposes that the laser cutting head is aligned with the peak and valley between two adjacent racks on the traction conveyor belt.
[0011] Furthermore, this application also proposes that a discharge channel is constructed on the discharge port of the folding machine, and a pressure plate is constructed above the discharge channel; the folding net in the discharge channel can only be pulled out of the discharge channel under the traction of the traction device.
[0012] Furthermore, this application also proposes that the counting gear and the traction conveyor belt rotate and start and stop synchronously, or that the counting gear drives the traction conveyor belt to run; the counting gear runs intermittently in units of the number of peaks of the folded mesh unit, and during two runs, the laser cutting machine cuts the end of the folded mesh to obtain the folded mesh unit.
[0013] As described above, the folding mesh unit forming equipment provided in this application includes a folding machine for forming mesh into folded mesh, a traction device disposed in the discharge direction of the folding machine, and a laser cutting machine for cutting the folded mesh into folded mesh units.

[0020] like Figure 1 As shown, this embodiment relates to a folding mesh unit forming device, including a folding machine 1 for forming a folded mesh 100, a traction device disposed in the discharge direction of the folding machine 1, and a laser cutting machine 3 for cutting the folded mesh 100 into folded mesh units. The traction device includes a traction conveyor belt 21 and a counting gear 22. A rack 211 adapted to the state of the folded mesh 100 is constructed on the surface of the traction conveyor belt 21. The counting gear 22 is disposed above the output end of the traction conveyor belt 21, and the gear surface 221 of the counting gear 22 is constructed to mesh with the rack 211 on the traction conveyor belt 21. The folded mesh 100 delivered by the folding machine 1 is fed into the meshing surface of the counting gear 22 and the traction conveyor belt 21, and is conveyed forward by the traction conveyor belt 21 to the laser cutting machine 3 for cutting.
[0021] The rack 211 on the traction conveyor belt 21 is adapted to the state of the folded net 100, ensuring accurate counting and positioning of the folded net 100 during the conveying process. The counting gear 22 meshes with the rack 211 on the traction conveyor belt 21, further ensuring accurate counting of the folded net 100 during the conveying process. A laser cutting head is moved in the laser cutting machine 3. The laser cutting head is set along the length direction of the rack 211 on the traction conveyor belt 21, aligning with the peaks and valleys between two adjacent racks 211 on the traction conveyor belt 21, thereby achieving precise cutting.
[0022] In a preferred embodiment, the counting gear 22 and the traction conveyor belt 21 can rotate and start / stop synchronously, or the counting gear 22 can drive the traction conveyor belt 21. The counting gear 22 operates intermittently, based on the number of peaks of the folded mesh unit. During two runs, the laser cutting machine 3 cuts the end of the folded mesh 100 to obtain folded mesh units. Specifically, the traction device, through the cooperation of the traction conveyor belt 21 and the counting gear 22, ensures accurate counting and positioning of the folded mesh 100 during the conveying process, thereby achieving efficient and precise cutting of folded mesh units. Compared with the prior art, the technical solution of this application is suitable for assembly line cutting of folded mesh units, improving the processing efficiency of folded mesh units.
[0023] Furthermore, this application proposes that a laser cutting head 31 is movable in the laser cutting machine 3, and the laser cutting head 31 is arranged along the length direction of the rack 211 on the traction conveyor belt 21. Specifically, the laser cutting head 31 can move along the length direction of the rack 211 in various ways. For example, the precise movement of the laser cutting head 31 can be achieved by a servo motor driving a ball screw, or rapid positioning can be achieved by a pneumatic device. As a preferred embodiment, the movement of the laser cutting head 31 can be controlled by an encoder synchronized with the traction conveyor belt 21, ensuring that the cutting head can accurately follow the movement of the rack 211. Thus, the laser cutting head 31 can accurately cut along the rack 211 of the folded mesh 100, improving the cutting accuracy and efficiency. The laser cutting head 31 is set along the length of the rack 211 on the traction conveyor belt 21. This feature ensures that the laser cutting head 31 can be accurately aligned with the peak and valley 212 between two adjacent racks 211 on the traction conveyor belt 21, ensuring the accuracy of the cutting position and avoiding the cutting errors and low efficiency caused by manual operation or inaccurate template installation in traditional methods.
[0024] Furthermore, this configuration allows the laser cutting head 31 to precisely align with the peaks and valleys 212 between two adjacent racks 211 on the traction conveyor belt 21, ensuring accurate cutting position and avoiding the cutting errors and inefficiencies caused by manual operation or inaccurate template installation in traditional methods. Specifically, the laser cutting head 31 is positioned along the length of the racks 211 on the traction conveyor belt 21 and configured to align with the peaks and valleys 212 between two adjacent racks 211. This configuration ensures that the laser cutting head 31 can be accurately positioned between the peaks and valleys 212 of the folded mesh 100, thereby achieving precise cutting. As a preferred embodiment, the laser cutting head 31 can detect the position of the racks 211 on the traction conveyor belt 21 using sensors or a vision system and automatically adjust its position to align with the peaks and valleys 212. In addition, the laser cutting head 31 can also move synchronously with the racks 211 of the traction conveyor belt 21 via a mechanical structure to ensure that it remains aligned throughout the cutting process. Compared with the prior art, the technical solution of this application does not require manual counting of the number of tooth peaks of the folded mesh 100, nor does it rely on a complex template system, thereby simplifying the cutting process and improving the processing efficiency of the folded mesh unit.
[0025] Furthermore, this application proposes that by setting a discharge channel 11 and a pressure plate 12 at the discharge port of the folding machine 1, the folded net 100 can only be moved by the traction device within the discharge channel 11, thereby preventing the folded net 100 from moving freely within the discharge channel 11. This ensures the stability and controllability of the folded net 100 during the discharge process, avoiding loose and messy discharge of the folded net 100, which would lead to a mismatch between the number of teeth of the folded net 100 and the traction device. Specifically, the construction of the discharge channel 11 restricts the folded net 100 during the discharge process, allowing it to move only along a predetermined path. The pressure plate 12 further ensures the stability of the folded net 100 within the discharge channel 11, preventing unnecessary deviation or shaking during movement. The traction action of the traction device ensures that the movement of the folded net 100 within the discharge channel 11 is controlled, preventing free movement. In a preferred embodiment, the pressure plate 12 can be made of an elastic material to provide sufficient pressure to stabilize the folded net 100 without affecting its movement. Furthermore, the inner wall of the discharge channel 11 can be designed as a smooth surface to reduce friction during movement of the folded net 100, thereby improving smoothness of movement. Thus, by setting the discharge channel 11 and pressure plate 12 at the discharge port of the folding machine 1, and combining this with the traction action of the traction device, this application effectively solves the problem of free movement of the folded net 100 in the discharge channel 11. Compared with the prior art, the technical solution of this application not only improves the stability and controllability of the folded net 100 during the discharge process, but also avoids the problem of loose and messy discharge of the folded net 100, thereby ensuring that the number of teeth of the folded net 100 corresponds to that of the traction device, improving production efficiency and product quality.
[0026] Furthermore, this application proposes that the counting gear 22 and the traction conveyor belt 21 rotate and start / stop synchronously, or that the counting gear 22 drives the traction conveyor belt 21. The counting gear 22 operates intermittently, based on the number of peaks of the folded mesh units. During two runs, the laser cutting machine 3 cuts the end of the folded mesh 100 to obtain folded mesh units. Specifically, the synchronous rotation and start / stop of the counting gear 22 and the traction conveyor belt 21, or the counting gear 22 driving the traction conveyor belt 21, ensures accurate counting and intermittent operation of the folded mesh units. The intermittent operation of the counting gear 22 based on the number of peaks of the folded mesh units ensures that the laser cutting machine 3 can accurately cut the end of the folded mesh 100 each time it runs, thereby obtaining folded mesh units. This design improves the processing efficiency of the folded mesh units by precisely controlling the conveying and cutting of the folded mesh 100. The synchronous rotation and start / stop of the counting gear 22 and the traction conveyor belt 21 can be achieved in various ways. For example, the start / stop of the counting gear 22 and the traction conveyor belt 21 can be controlled by an electronic control system to ensure that they operate synchronously at precise times. Furthermore, the counting gear 22 driving the traction conveyor belt 21 can be achieved through mechanical connection or electronic control, ensuring that the rotation of the counting gear 22 is accurately transmitted to the traction conveyor belt 21. Thus, this application solves the technical problem of low processing efficiency of folded mesh units by precisely controlling the conveying and cutting of the folded mesh 100. Compared with the prior art, the technical solution of this application does not require manual counting of the number of tooth peaks of the folded mesh 100, nor does it require the use of a large template, thereby simplifying the processing of the folded mesh unit and improving processing efficiency.
