[0001] The utility model belongs to the field of conductive foam processing, and specifically relates to a conductive foam cutting device. Background Art

[0002] Conductive foam is a flame-retardant sponge wrapped with conductive cloth. After a series of treatments, it has good surface conductivity and can be easily fixed on the device to be shielded with adhesive tape. When encountering radio waves, it will reflect and absorb according to the properties of the object, providing excellent shielding effect. It is widely used in electronic products such as PDP TVs, LCD monitors, LCD TVs, mobile phones, notebook computers, communication cabinets, medical instruments, as well as military and aerospace fields.

[0003] Before using the conductive foam, it is necessary to cut it according to the needs. At present, in the cutting process, the cutting device is used more and more widely instead of manual cutting. However, in the existing cutting device, the conductive foam is easily offset during the conveying process of the conductive foam, resulting in the tilt of the cut end of the conductive foam, causing the length deviation, which affects the appearance of the product and the product quality.

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, upper end, lower end, top, bottom...) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0026] See also Figure 1-2As shown, a conductive foam cutting device comprises a workbench 1, on which a conveying module 2 for conveying conductive foam and a cutting module 3 for cutting the conductive foam are provided; a limiting module 4 for limiting the moving conductive foam is provided on the workbench 1 between the conveying module 2 and the cutting module 3; the limiting module 4 comprises a pair of limiting roller assemblies 41 arranged at intervals, and a pair of the limiting roller assemblies 41 are respectively arranged on the workbench 1 through a corresponding connecting seat 42, wherein one group of the limiting roller assemblies 41 is fixedly connected to its corresponding connecting seat 42, and the other group of the limiting roller assemblies 41 is movably arranged on its corresponding connecting seat 42 through an adjusting assembly 43, thereby realizing the adjustment of the spacing between the pair of limiting roller assemblies 41, and then realizing the limiting of the conductive foam cutting of different widths, thereby improving the application range of the device.

[0027] Among them, see Figure 2-3 As shown, in the present embodiment, a pair of the limiting roller assemblies 41 each include a connecting frame 411 with a U-shaped cross-section, and a row of rotatable limiting rollers 412 are evenly distributed in the U-shaped groove of the connecting frame 411; when connected, one group of the connecting frames 411 is fixedly connected to its corresponding connecting seat 42, and the other group of the connecting frames 411 is movably arranged on its corresponding connecting seat 42 through an adjusting assembly 43. At this time, the limiting rollers 412 arranged in a pair of the connecting frames 41 are relative.

[0028] See also Figure 3-4 As shown, in this embodiment, the adjustment component 43 includes two groups of guide shafts 431 that can be slidably inserted into the connecting seat 42. Of course, the above is only one embodiment and is not intended to limit the scope of the present application. More groups can be set in actual settings, and they can be set according to specific needs; after the outer ends of the guide shafts 431 are connected together through a connecting block 432, a nut 433 is screwed on each of them, and the connecting block 432 is restricted on the guide shaft 431 by the nut 433; a bolt 434 with a front end that can be threadedly connected to the connecting seat 42 is inserted into the middle of the connecting block 432; a spring 435 is also sleeved on each of the guide shafts 431; when connected, continue to refer to Figure 3As shown, after the guide shaft 431 is connected with the corresponding connecting frame 411 respectively, it passes through the connecting seat 42, and the spring 435 is sleeved on the outer surface of the passing through, and then the connecting block 432 is installed, and the nut 433 is screwed on. At this time, the spring 435 is compressed between the connecting seat 42 and the connecting block 432. In the absence of external force, the spring 435 has a tendency to drive the connecting block 432 to move outward. At this time, another group of the connecting frames 411 is in contact with the connecting seat 42, and the distance between the limiting rollers 412 set in a pair of the connecting frames 41 is the largest; finally, after the bolt 434 passes through the connecting block 432, its front end is screwed into the connecting seat 42 to complete the assembly.

[0029] During use, when it is necessary to adjust the spacing between the limiting rollers 412, the bolt 434 is screwed into the connecting seat 42 so that the countersunk head of the bolt 434 presses the connecting block 432, thereby driving the connecting block 432 to move closer to the connecting seat 42, thereby driving the guide shaft 431 and the limiting roller 412 connected to the guide shaft 431 to move inward, thereby reducing the spacing between the two groups of limiting rollers 412; when the bolt 434 is screwed outward from the connecting seat 42, the connecting block 432 moves away from the connecting seat 42 under the reaction of the spring 435, thereby driving the guide shaft 431 and the limiting roller 412 connected to the guide shaft 431 to move outward, thereby increasing the spacing between the two groups of limiting rollers 412.

[0030] In addition, see Figure 5 As shown, in this embodiment, the conveying module 2 includes a pair of rollers 21 distributed up and down, and a bearing seat 22 is respectively provided at both ends of the pair of rollers 21. The pair of rollers 21 are rotatably arranged between a pair of fixed plates 23 through the corresponding bearing seats 22, and one end of the roller 21 located at the lower end is connected to a reduction motor 24, and the reduction motor 24 is fixed to the fixed plate 23 on the corresponding side through a support seat 25.

[0031] For further information, see Figure 5 As shown, in this embodiment, the two groups of rollers 21 are connected by a gear assembly 26, and the gear assembly 26 includes a first gear 261 sleeved on the lower end roller 21 and a second gear 262 sleeved on the upper end roller 21, the first gear 261 and the second gear 262 are meshingly connected, and both use spur gears.

[0032] This is, see Figure 6As shown, in the present embodiment, the cutting module 3 comprises a gantry 31, on which a vertically downward cylinder 32 is arranged, and the cylinder 32 is a slide cylinder, and a connecting plate 33 is arranged at the front end of the piston rod of the cylinder 32, and a cutting knife 34 is arranged on the connecting plate 33, and the conductive foam is cut by the cutting knife 34; the cutting module 3 also comprises two sets of guide rails 35, and the guide rails 35 are arranged between the connecting plate 33 and the gantry 31, and the guide rails 35 are parallel to the running direction of the piston rod of the cylinder 32, and the guide rails 35 are cylindrical guide rails, and when connected, the track of the guide rails 35 is connected to the gantry 31, and the slide of the guide rails 35 is connected to the connecting plate 33.

[0033] The working principle of the utility model is as follows:

[0034] Before use, the distance between the pair of limiting roller assemblies 41 is adjusted to a proper position according to the width of the conductive foam.

[0035] When the conductive foam needs to be cut, the starting end of the conductive foam is placed between the rollers 21. Under the action of the rollers 21, the conductive foam is transported forward and enters between a pair of limiting roller assemblies 41. At this time, the two ends of the conductive foam in the width direction are respectively in contact with the limiting rollers 412 on the corresponding sides. The conductive foam is limited by the limiting rollers 412 to prevent it from shifting. As the conductive foam moves forward, the limiting rollers 412 rotate, which is beneficial to reducing the friction when limiting the conductive foam. After the conductive foam is transported to the cutting module 3 through the limiting roller assembly 41, the cylinder 32 drives the cutter 34 to move downward through the connecting plate 33 to achieve cutting of the conductive foam.

[0036] During cutting, by controlling the cutting module 3, the cutting length of the conductive foam can be adjusted, and the conductive foam can be switched between half cutting and full cutting.

[0037] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
