Description

Technical Field

[0001] The invention belongs to the technical field of expanded metal processing, and in particular relates to a cutting device for producing and manufacturing expanded metal. Background Art

[0002] After the expanded metal mesh completes the production and processing steps, it needs to be cut into strips with the help of cutting equipment. Through this operation, the width of the expanded metal mesh can be accurately controlled within a specific range, thereby meeting the actual needs of the expanded metal mesh's subsequent use.

[0003] When cutting expanded metal into strips, rotating disc knife cutting is a more common operation method. However, during the circular blade cutting operation on the expanded metal, debris will inevitably accumulate in the cutting groove of the abutment roller. As the cutting work continues, these debris will continuously increase the wear of the circular blade in the cutting groove, resulting in excessive wear. This excessive wear will directly cause the edges of the cut expanded metal to be jagged, which not only seriously reduces the cutting quality of the expanded metal, but also makes the cut expanded metal unable to meet the precision standards required by subsequent processing links.

DETAILED DESCRIPTION

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0029] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0030] In the description of the present invention, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0031] Example 1: Reference Figure 1 and Figure 2 A cutting device for producing expanded metal comprises a frame 1 and a cutting roller 2 and an abutting roller 3, both of which are rotatably arranged on the frame 1. An L-shaped mounting plate 4 is fixedly connected to one side of the frame 1, and a driving part 41 is installed on the L-shaped mounting plate 4. The output end of the driving part 41 is connected to one end of the cutting roller 2. A driving gear 22 located on the other side of the frame 1 is fixedly connected to the cutting roller 2. A matching driven gear 23 is connected to the surface of the driving gear 22. The driven gear 23 is fixedly connected to the surface of the abutting roller 3. A plurality of equidistant circular blades 21 are connected along the length direction of the cutting roller 2, and a cutting groove 31 corresponding to the circular blades 21 is provided on the abutting roller 3.

[0032] When the steel mesh is cut into strips, first, the steel mesh to be cut is transported between the cutting roller 2 and the abutting roller 3 with the help of an external guiding mechanism, and then the driving part 41 using a servo motor is started. The output end of the driving part 41 drives the cutting roller 2 to rotate. When the cutting roller 2 rotates, the driving gear 22 fixed thereon will also rotate accordingly. Since the driving gear 22 is adapted to mesh with the driven gear 23 on the surface of the abutting roller 3, the rotation of the driving gear 22 will drive the driven gear 23 to rotate, thereby causing the abutting roller 3 to rotate synchronously. At the same time, a plurality of circular blades 21 equidistantly connected along the length direction on the cutting roller 2 will rotate together with the cutting roller 2. During the rotation of the circular blades 21, they will cooperate with the cutting grooves 31 on the abutting roller 3 to cut the steel mesh located between the two.

[0033] Example 2: Reference Figures 1-6 , considering that when the circular blade 21 cuts the steel plate mesh, debris will inevitably remain in the cutting groove 31. If these debris are not cleaned in time, the excessive wear of the circular blade 21 in the cutting groove 31 will be accelerated, resulting in uneven edges of the cut steel plate mesh, which not only reduces the cutting quality of the steel plate mesh, but also affects the subsequent processing accuracy of the steel plate mesh. Therefore, on the basis of the above-mentioned embodiment 1, a circular cavity 32 is also provided inside the abutting roller 3, and a plurality of circumferentially distributed filter holes 33 are connected between the inner wall of the cutting groove 31 and the inner wall of the circular cavity 32. A first air guide pipe 34 is passed through the two ends of the abutting roller 3, and the first air guide pipe 34 is fixedly connected to the L-shaped mounting plate 4. The surface of the first air guide pipe 34 is connected to a plurality of first nozzles 35 located inside the circular cavity 32. The first nozzle 35 corresponds to the position of the cutting groove 31, and both ends of the first air guide pipe 34 are connected to an air guide mechanism.

[0034] In the present technical solution, since the first air guide tube 34 is fixedly supported by the L-shaped mounting plate 4 and can stably pass through the circular cavity 32 laterally, when the abutment roller 3 rotates, the cutting groove 31 on the abutment roller 3 will rotate along the first air guide tube 34. At the same time, the air guide mechanism synchronously linked with the cutting roller 2 is started to introduce gas into the first air guide tube 34. Subsequently, the gas is blown to each filter hole 33 on the inner wall of the cutting groove 31 in turn through the first nozzle 35, thereby effectively cleaning the debris at the cutting groove 31. This design reduces the additional wear of the circular blade 21 caused by the interference of debris during the cutting process, so that the circular blade 21 can maintain a sharper cutting state, which not only improves the cutting quality of the steel plate mesh, but also reduces the replacement frequency and maintenance cost of the circular blade 21.

[0035] It should be noted that the first nozzle 35 is arranged vertically downward, and the air outlet direction of the first nozzle 35 is toward the inner port position close to the filter hole 33. This means that when the multiple filter holes 33 on the cutting groove 31 are rotated to the air outlet direction of the first nozzle 35, the airflow ejected by the first nozzle 35 can impact the debris remaining at the filter hole 33 with the shortest path and maximum force, so that the debris falls smoothly to the bottom of the abutting roller 3, greatly improving the efficiency and thoroughness of debris cleaning.

[0036] In the above technical solution, in order to realize that the air guide mechanism supplies air to the first air guide pipe 34 with the help of the power of the cutting roller 2, the air guide mechanism includes a vertical air guide cylinder 5, and the surface of the vertical air guide cylinder 5 is fixedly connected to a connecting plate 6, one side of the connecting plate 6 is fixedly connected to the vertical plate above the frame 1, and an air guide cavity 51 is opened inside the vertical air guide cylinder 5, and a moving block 52 is slidably connected to the inner wall of the air guide cavity 51, and a spring 53 is fixedly connected between the top of the moving block 52 and the top wall of the air guide cavity 51, and a lifting rod 54 is fixedly connected to the bottom of the moving block 52, and the lifting rod 54 passes through one end of the bottom of the vertical air guide cylinder 5 and is fixedly connected to a semicircular resistance block 55, and the surface of the semicircular resistance block 55 is fitted with a toggle portion fixedly connected to the cutting roller 2.

[0037] When the toggle part rotates through the cutting roller 2 and cooperates with the moving block 52 to slide upward along the inner wall of the air guide cavity 51, the top of the vertical air guide cylinder 5 is connected to the first air pipe 56, and the end of the first air pipe 56 away from the top of the vertical air guide cylinder 5 is connected to the end of the first air guide pipe 34. This design allows the toggle part with a cam structure to squeeze the lifting rod 54 on the semicircular resistance block 55 as the cutting roller 2 rotates, thereby pushing the moving block 52 to slide upward along the inner wall of the air guide cavity 51 to squeeze the spring 53. In this process, the gas in the air guide cavity 51 enters the first air guide pipe 34 through the first air pipe 56, and is finally sprayed from the first nozzle 35 to the inner port position of the filter hole 33, thereby effectively cleaning the debris in the cutting groove 31.

[0038] Example 3: Reference Figure 5-Figure 8 On the basis of the above-mentioned embodiment 2, when the toggle portion rotates through the cutting roller 2 to cooperate with the moving block 52 to slide downward along the inner wall of the air guide cavity 51, the surface of the vertical air guide cylinder 5 is connected to the second air pipe 57, and the end of the second air pipe 57 away from the surface of the vertical air guide cylinder 5 is connected to the second air guide pipe 58. The second air guide pipe 58 is fixedly connected to the frame 1 horizontally, and the surface of the second air guide pipe 58 is connected to a second nozzle 59 corresponding to the cutting groove 31. The second air pipe 57 is connected to one end inside the vertical air guide cylinder 5, close to the area corresponding to the bottom wall of the air guide cavity 51 and the bottom of the moving block 52. The second nozzle 59 is horizontal, and the air outlet direction of the second nozzle 59 is toward the outer port near the cutting groove 31.

[0039] Through such a design, when the moving block 52 slides downward along the inner wall of the air guide cavity 51, it will produce a downward squeezing effect on the gas inside the air guide cavity 51. The squeezed gas enters the second air guide duct 58 through the second air pipe 57, and is then sprayed from the second nozzle 59 to the cutting groove 31. This process realizes the cooling of the cutting groove 31. The cooled cutting groove 31 can reduce the adhesion of debris. At the same time, when the gas sprayed from the second nozzle 59 is blown to the inner wall of the cutting groove 31, it can also loosen some debris that is more tightly attached. When these loosened debris rotates to the first nozzle 35 with the abutment roller 3, they will fall more easily, thereby further improving the efficiency of the first nozzle 35 in handling the debris of the cutting groove 31, so that the circular blade 21 has a cleaner cutting environment and a more stable cutting effect in the subsequent cutting process. The quality of the cut steel plate mesh is more guaranteed, and the service life of the circular blade 21 is also extended, and the production cost is reduced.

[0040] Example 4: Reference Figure 7 and Figure 8 On the basis of the above-mentioned embodiment 3, considering that the frequency of the cam structure's toggle portion repeatedly squeezing the semicircular resistance block 55 is low, based on this problem, the toggle portion adopts a disc structure, which includes a toggle disc 510 fixedly connected to the cutting roller 2, and five circumferentially distributed arc-shaped pieces 511 fixedly connected to the surface of the toggle disc 510. When the cutting roller 2 rotates, the semicircular resistance block 55 intermittently interferes with the toggle disc 510 and the arc-shaped piece 511 respectively.

[0041] Compared with the previous cam structure, this disc structure is provided with multiple arc-shaped pieces 511. At the same rotation speed of the cutting roller 2, the frequency of the semicircular resistance block 55 being squeezed is greatly increased. The higher squeezing frequency means that the moving block 52 slides more frequently along the inner wall of the air guide cavity 51, thereby increasing the number of times the gas in the air guide cavity 51 is squeezed. In this way, the gas flow rate and injection frequency sprayed from the first nozzle 35 and the second nozzle 59 to the cutting groove 31 will increase. On the one hand, the cutting groove 31 can be cooled more efficiently and the possibility of debris adhesion in a high temperature environment can be reduced; on the other hand, frequent gas blowing can more effectively loosen the debris tightly attached to the inner wall of the cutting groove 31. Combined with the subsequent cleaning action of rotating to the first nozzle 35, it can significantly improve the efficiency of the entire system in handling the debris in the cutting groove 31, ensure that the circular blade 21 performs cutting operations in a cleaner and more suitable environment, and improve the cutting quality and efficiency.

Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention.
