[0002] The filter screen is the most commonly used component in the air purification field, generally including a frame and a mesh cloth arranged on the frame. The mesh cloth generally adopts a folding net to increase the filtering area. The folding net is cut and then fixed on the frame. The existing jigs for producing the folding net have a rack and a groove on the upper end surface of the entire bottom plate. When the folding net is installed on the folding net jigs, each peak and valley of the folding net needs to be aligned with the rack and groove of the jigs. Then, the peaks and valleys at the corresponding positions are cut off at every interval of the number of teeth of the folding net unit. The other positions cannot be cut off due to the lack of support.

[0003] The traditional folding net jigs and cutting method have the following problems. First, the installation process of the folding net unit is complicated, and each peak and valley needs to be accurately aligned, which increases the production time and labor cost. Second, the cutting can only be performed at specific positions, which limits the flexibility and diversity of the folding net unit. More importantly, when the folding net unit is installed on the frame, the peaks and valleys of the edge teeth of the folding net unit only slightly contact the edge of the frame, and the adhesion area is small, which makes the adhesion difficult. This leads to the separation of the folding net unit and the frame, which seriously affects the product quality and service life. SUMMARY

[0012] Further, the application also proposes that the two groups of knife heads of the cutting knife can adjust the gap to adapt to the width of the two side cut grooves of the cutting tooth.

[0013] Further, the application also proposes that the knife head of the cutting knife is constructed as an electric heating wire, and the knife head is used to cut off the folding net in the cut groove in the electrified state of the cutting knife.

Embodiments

[0023] AsFigure 1 and 2 As shown, this embodiment relates to a folding mesh template, including a template body 1. The top surface of the template body 1 is constructed as a serrated surface 10 for embedding a folding mesh 100. The serrated surface 10 includes multiple toothed strips 11, with grooves 12 formed between adjacent toothed strips 11. Among the multiple toothed strips 11 of the serrated surface 10, a cutting tooth 13 is constructed every other tooth of a folding mesh unit. The cutting tooth 13 has a slit groove 14 adapted to a cutter, which is recessed at least on both sides of the tooth peak. Specifically, by constructing a cutting tooth 13 every other tooth of the multiple toothed strips 11 of the serrated surface 10, and constructing a slit groove 14 recessed on both sides of the tooth peak of the cutting tooth 13, the cutter can adapt to these slit grooves 14 for cutting. This design provides cutting teeth 13 and notch grooves 14 at specific locations, allowing cutting to occur at the center of the tooth peaks of the cutting teeth 13. Compared to cutting at the peaks and valleys, this design reserves a portion of the folded mesh 100 at the edge of the folded mesh unit for bonding to the frame, thereby solving the problem of poor contact between the edge tooth peaks of the folded mesh unit and the edge of the frame, increasing the bonding area, reducing the bonding difficulty, improving product quality, and reducing the possibility of the folded mesh unit separating from the frame.

[0024] Therefore, by constructing cutting teeth 13 and slit grooves 14 on the serrated surface 10 of the folded mesh template, this application effectively solves the problems of poor contact between the folded mesh unit and the frame edge, small bonding area, and high bonding difficulty in the prior art, thereby improving the quality and stability of the product.

[0025] The cutting tooth 13 can be constructed in several ways. The first implementation scheme is as follows: Figure 1 As shown, the tooth peaks 15 of the cutting tooth 13 can be constructed to be identical to those of the other toothed racks 11, and slit grooves 14 are constructed in the middle of the inclined surfaces on both sides of the tooth peak 15. Specifically, the tooth peak 15 structure of the cutting tooth 13 is consistent with that of the other toothed racks 11, ensuring the overall coordination of the cutting tooth 13 on the serrated surface 10. The design of the slit grooves 14 in the middle of the inclined surfaces on both sides of the tooth peak 15 allows the slit grooves 14 to better adapt to the cutter, thereby improving the cutting accuracy and efficiency. This design, by maintaining the consistency of the tooth peaks 15 and increasing the adaptability of the slit grooves 14, and by ensuring the flatness of the folded mesh 100 during cutting, solves the technical problem of adapting the cutting tooth 13 to the cutter, ensuring the stability of the cutting process and product quality. Therefore, this application solves the technical problem of adapting the cutting tooth 13 to the cutter by constructing the tooth peaks 15 of the cutting tooth 13 identical to those of the other toothed racks 11 and constructing slit grooves 14 in the middle of the inclined surfaces on both sides of the tooth peak 15. This design not only improves the accuracy and efficiency of cutting, but also ensures the stability of the cutting process and product quality, which has significant advantages compared with existing technologies.

[0026] The second embodiment is as shown in Figure 2 As shown in the figure, the tooth peak 15 of the cutting tooth 13 can also be designed as a flat surface connecting the two side cutting grooves 14. These different designs can be selected according to actual needs to ensure that the cutting tool can fit the cutting groove 14 for cutting. The tooth peak 15 of the cutting tooth 13 can be designed as a flat surface connecting the two side cutting grooves 14, which further enhances the adaptability of the cutting groove 14 to the cutting tool, making the cutting process more smooth. In addition, the tooth peak 15 of the cutting tooth 13 can also be adjusted according to actual needs, such as by changing the depth or width of the cutting groove 14, to adapt to different types of cutting tools and cutting needs. Specifically, the tooth peak 15 of the cutting tooth 13 is designed as a flat surface connecting the two side cutting grooves 14, which makes the cutting tooth 13 more stable in the cutting process, ensuring the accuracy and efficiency of cutting. Through this structural design, the cutting tooth 13 can better adapt to the working requirements of the cutting tool, and the tooth peak 15 is designed as a flat surface during cutting to avoid interference with the cutting tool, thereby improving the cutting quality and production efficiency.

[0027] Among them, the tooth peak 15 of the cutting tooth 13 is designed as a flat surface 16 connecting the two side cutting grooves 14, which can be achieved in various ways. For example, the tooth peak 15 of the cutting tooth 13 can be partially machined into a flat surface 16 by mechanical processing, so that it is smoothly connected with the two side cutting grooves 14. As a preferred embodiment, the shape of the tooth peak 15 of the cutting tooth 13 can also be precisely controlled by numerical control machining technology to ensure that the connecting part of the tooth peak 15 and the cutting groove 14 achieves the best matching effect.

[0028] Further, the application also proposes that the number of teeth of the folding net unit is A, the number of the rack 11 constructed on the sawtooth surface 10 is N*A+N-1, and N is greater than or equal to 2. Specifically, there is a specific mathematical relationship between the number of teeth A of the folding net unit and the number of the rack 11 on the sawtooth surface 10. This relationship ensures that every certain number of the rack 11 on the sawtooth surface 10 is constructed with a cutting tooth 13. Through this design, it can be ensured that the cutting tooth 13 constructed on the folding net template can effectively match the number of teeth of the folding net 100, thereby achieving accurate cutting of the folding net 100. As a preferred embodiment, when the number of teeth of the folding net unit is 11 teeth, 23 racks 11 are constructed on the sawtooth surface 10, and the 12th tooth is constructed as a cutting tooth 13. In this way, by constructing a specific number of racks 11 and cutting teeth 13 on the sawtooth surface 10, it can be ensured that the cutting tooth 13 constructed on the folding net template can effectively match the number of teeth of the folding net 100, thereby achieving accurate cutting of the folding net 100. This technical feature solves the problem of ensuring the relationship between the number of cutting teeth 13 and the number of teeth of the folding net unit when constructing the cutting tooth 13 on the folding net template, so as to achieve effective cutting, by setting the mathematical relationship. This scheme can obtain multiple folding net units on the template at one time.

[0029] As a preferred embodiment, the construction of the cutting tooth 13 can be achieved by constructing a cutting groove 14 adapted to the cutting knife in the middle of the two sides of the tooth peak 15. For example, the tooth peak 15 of the cutting tooth 13 can be constructed the same as other racks 11, the middle of the two side slopes of the tooth peak 15 is constructed with a cutting groove 14, or the tooth peak 15 of the cutting tooth 13 is constructed as a flat surface 16 connecting the two side cutting grooves 14. These different construction methods can be selected and adjusted according to actual production needs. In this way, by setting the number of teeth of the folding net unit to 11 teeth and constructing 23 racks 11 on the sawtooth surface 10, it is ensured that the number of racks 11 on the sawtooth surface 10 matches the number of teeth of the folding net unit. The 12th tooth on the sawtooth surface 10 is constructed as a cutting tooth 13, which makes the cutting tooth 13 effectively cut at a specific position of the folding net 100, thereby increasing the bonding area of the folding net unit and the frame, reducing the bonding difficulty, reducing the risk of separation of the folding net unit and the frame, and improving the product quality. Compared with the prior art, the technical scheme of the application significantly improves the connection stability of the folding net unit and the frame by increasing the bonding area and reducing the bonding difficulty, thereby ensuring the quality of the product. EMBODIMENT

[0030] As Figures 1-3As shown, the present embodiment also proposes a folding net cutting assembly, which includes a folding net guide and a cutting knife 2. The folding net guide adopts the folding net guide design described in embodiment 1, ensuring that the sawtooth surface 10 design of the guide can accurately correspond to the rack 11 and the tooth groove 12 of the folding net 100. The cutting knife 2 is provided with two sets of knife heads that are synchronously adapted to the two side cutout grooves 14 of the cutting teeth 13. This design enables the knife heads to accurately enter the cutout grooves 14 during the cutting process, achieving accurate cutting of the folding net 100. Specifically, the two sets of knife heads of the cutting knife 2 can be designed to adjust the gap to adapt to the width of the two side cutout grooves 14 of the cutting teeth 13. As a preferred embodiment, the knife heads of the cutting knife 2 can be constructed as electric heating wires, which are used to cut off the folding net 100 in the cutout groove 14 when the cutting knife 2 is powered on. Thus, the accurate matching between the cutting knife 2 and the folding net guide is achieved, thereby improving the accuracy and efficiency of cutting.

[0031] The folding net cutting assembly ensures that the sawtooth surface 10 design of the guide can accurately correspond to the rack 11 and the tooth groove 12 of the folding net 100 by using the aforementioned folding net guide. The two sets of knife heads 21 on the cutting knife 2 are designed to be synchronously adapted to the two side cutout grooves 14 of the cutting teeth 13, so that the knife heads 21 can accurately enter the cutout grooves 14 during the cutting process, achieving accurate cutting of the folding net 100. This design ensures the accurate matching between the cutting knife 2 and the folding net guide, thereby improving the accuracy and efficiency of cutting, solving the technical problem of the adaptation of the cutting knife 2 to the folding net guide. Compared with the prior art, the technical solution of the present application significantly improves the accuracy and efficiency of cutting by precise guide design and synchronous adaptation of the cutting knife 2 heads, solving the problem of poor adaptation of the cutting knife 2 to the folding net guide in the prior art.

[0032] Specifically, the two sets of knife heads 21 of the cutting knife 2 can adjust the gap through mechanical adjustment or electronic control system to adapt to different widths of the cutout grooves 14. For example, the gap of the knife heads 21 can be fine-tuned by rotating a nut or using an electric motor to ensure the accurate matching of the knife heads 21 and the cutout grooves 14. As a preferred embodiment, the knife heads 21 can be designed as a telescopic structure, whose extension and retraction are controlled by a hydraulic or pneumatic system, thereby achieving the adjustment of the gap. Thus, the cutting knife 2 can be adjusted according to the width of the two side cutout grooves 14 of the cutting teeth 13, thereby achieving more accurate cutting. This adjustment function ensures the adaptability between the cutting knife 2 and the cutout grooves 14 of the cutting teeth 13, improving the accuracy and efficiency of cutting. Compared with the prior art, the technical solution of the present application solves the technical problem of the adaptation of the cutting knife 2 to the two side cutout grooves 14 of the cutting teeth 13 by adjusting the gap of the knife heads 21, significantly improving the accuracy and efficiency of cutting.
