Detailed Description
The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.
Example (b): as shown in fig. 1, 2, 3, 4, 5, 6 and 7, the waterproof conductive composite multilayer fabric comprises a conductive layer 11, a main bonding layer 12 and a waterproof layer 13 from inside to outside, and further comprises an inner bonding layer 1 arranged on the inner side surface of the conductive layer 11, a wear-resistant layer 2 arranged on the inner bonding layer 1, a reinforcing layer 3 arranged on the outer side surface of the main bonding layer 12, and an outer bonding layer 4 arranged on the outer side surface of the reinforcing layer 3.
The thickness of the multilayer fabric is 0.52-0.60mm, and the total thickness of the main bonding layer 12, the inner bonding layer 1 and the outer bonding layer 4 accounts for 42-45% of the thickness of the multilayer fabric.
The material of conducting layer 11 is aluminium foil fiber composite cloth, the material of waterproof layer 13 is waterproof oxford, the material of main part tie coat 12, interior tie coat 1 and outer tie coat 4 is the polyurethane adhesive.
The wear-resistant layer 2 is made of polyester fiber cloth, and the reinforcing layer 3 is made of composite polyamide fiber cloth.
A composite technology of a waterproof conductive composite type multilayer fabric is characterized in that after the multilayer fabric is bonded and compounded, continuous cloth pressing operation is carried out through a compression roller, and the downward pressure on the multilayer fabric is 5-45 kg.
In this embodiment, the overall process of compounding the multilayer fabric starts from the application of the binder after the material selection, and after the seven layers of fabrics are sequentially attached, such operations as heating, drying, sizing and pressing rollers can be performed in the manner of the prior art, so as to ensure that the final multilayer fabric has high bonding strength, and each layer of functional single fabric has effective performance of various compounding.
In addition, in the embodiment, the self weight of the cloth pressing roller is set to be 10-25kg, and the cloth pressing downward pressure can meet the range of 5-45kg through a specific cloth pressing roller structure.
The cloth pressing machine comprises two side mounting plates 1, rectangular mounting holes 2 arranged on the side mounting plates 1, vertical mounting studs 3 arranged in the rectangular mounting holes 2, a cloth pressing roller fixing shaft unit 4 arranged on the vertical mounting studs 3 in a sleeved mode after holes are formed in the vertical mounting studs, and adjusting screw ring units 5 arranged on the vertical mounting studs 3 and used for lifting, rigidly pressing and elastically pressing the cloth pressing roller fixing shaft unit 4.
In the prior art, the mounting modes of the cloth pressing roller are mainly two types: firstly, the upper parts of two ends of a roll shaft are fixedly clamped; secondly, set up the spring above the roller both ends, these two kinds of modes then have following several problems: firstly, when a thick fabric is pressed, only relatively large downward pressure can be provided, when a thin fabric passes through, the relative downward pressure is small, and the effects that the thick fabric is pressed down in a small width and the thin fabric is pressed down in a large force cannot be achieved; secondly, the lowest downward pressure is the dead weight of the cloth pressing roller and cannot be reduced, which is not convenient enough in the using process.
Therefore, in view of the above problems, the adjusting screw ring unit 5 and the cloth pressing roller fixing shaft unit 4 in the present embodiment not only have the two ways of "rigid pressing" and "elastic pressing", but also have the ability to "lift" the cloth pressing roller fixing shaft unit 4, that is, the minimum pressing force can break through the self weight of the cloth pressing roller, which makes the cloth pressing operation very flexible and effective.
More importantly, in the present embodiment, the specific connection structure between the adjusting screw ring unit 5 and the cloth pressing roller fixing shaft unit 4 enables the three structures of "rigid pressing down", "elastic pressing down" and "lifting" to be integrated together, and the three structures can be simply adjusted and switched, so as to finally meet various cloth pressing requirements for different fabrics.
The cloth pressing roller fixing shaft unit 4 comprises a fixing circular shaft body 401, an upper tangent plane 402 which is inwards arranged from the end face of the fixing circular shaft body 401, a vertical mounting hole 403 which is downwards arranged from the upper tangent plane 402 and is used for inserting the vertical mounting stud 3, a mounting ring part 404 which is arranged on the upper tangent plane 402, is sleeved outside the vertical mounting hole 403 and is used for lifting the fixing circular shaft body 401 in a rope connection mode with the adjusting screw ring unit 5, and a clamping annular groove 405 which is arranged on the upper tangent plane 402, is sleeved outside the mounting ring part 404 and is used for receiving the elastic downward pressure of the adjusting screw ring unit 5.
In this embodiment, the inner annular surface of the vertical mounting hole 403 is smooth and is not provided with threads, so that the whole cloth pressing roller associated with the fixed circular shaft body 401 can move up and down, the mounting ring part 404 is an action part of the above-mentioned "lifting" type cloth pressing manner, the clamping annular groove 405 is an action part of the above-mentioned "elastic pressing" type cloth pressing manner, and the "rigid pressing" type cloth pressing manner directly acts on the upper tangent plane 402, so that the downward pressure of the cloth pressing roller on the lower side passing through the fabric is not limited by the thickness of the fabric, the cloth pressing roller can be independently adjusted, and the upper and lower limit ranges of the values are relatively large.
The mounting ring portion 404 includes a connecting annular groove 404a provided in the upper cut plane 402, a connecting annular ring 404b provided in the connecting annular groove 404a, an annular cut plane 404c provided in the connecting annular ring 404b, and a set-up fixing bolt 404d which is screwed downward from the annular cut plane 404c and is inserted into and screwed into the inner bottom surface of the connecting annular groove 404 a. The adjusting screw ring unit 5 includes an internally threaded ring 501 provided on the vertical mounting stud 3, a connecting cord 502 provided on a lower surface of the internally threaded ring 501, an opening ring 503 provided on the connecting cord 502 and connected to the connecting ring 404b by snap-fitting for suspending the fixed shaft body 401 when the internally threaded ring 501 rotates upward, and a pressing portion 504 provided on a lower surface of the internally threaded ring 501 at a position radially outside the connecting cord 502 and for rigidly pressing down and elastically pressing down the fixed shaft body 401.
In this embodiment, when the cloth pressing operation pressure of the multilayer fabric needs to be relatively small and is smaller than the weight of the cloth pressing roller, the operation method is to clamp the opening ring 503 and the connecting ring 404b, and the connecting rope 502 is stretched straight, so that the cloth pressing roller can be suspended by the internal thread ring 501, and the purpose that the cloth pressing pressure is smaller than the weight of the cloth pressing roller is achieved, and the connecting rope 502 is made of an elastic rubber rope with appropriate elasticity, so that the internal thread ring 501 can move up and down properly and the cloth pressing pressure can be adjusted within the relatively small range on the premise that the connecting rope 502 is stretched straight.
The lower opening of the opening ring 503 is used for avoiding the fixing bolt 404d for erecting during rotation, and the central angle degree range of the opening ring 503 is 300-320 degrees, which needs to be relatively larger to ensure sufficient clamping and hooking effects.
The pressing portion 504 includes an annular receiving groove 504a provided on the lower surface of the female screw ring 501 and located outside the connecting string 502, a drive spring 504b provided in the annular receiving groove 504a and configured to elastically press down the fixed shaft body 401 on the engaging annular groove 405, a rigid pressing block 504c provided on the lower surface of the female screw ring 501 and located outside the annular receiving groove 504a and configured to press down the fixed shaft body 401, and a radial direction adjusting bolt 504d that is screwed to the rigid depressing block 504c, and that blocks and stores the driving spring 504b downward when the rigid depressing block 504c rigidly depresses the fixed shaft body 401, and that restricts and fixes the driving spring 504b upward when the driving spring 504b elastically depresses the fixed shaft body 401.
In this embodiment, when the fixing and limiting above the fixing circular shaft 401 is required, the internal threaded ring 501 may be rotated downward until the rigid downward-pressing block 504c presses on the upper tangent plane 402, and because the fabric itself has elasticity, when the rigid downward-pressing block 504c abuts against the upper tangent plane 402, there is a range of up-and-down adjustment, which can ensure the above-mentioned "rigid downward-pressing" manner to be effective and adjustable.
In addition, the internal thread ring 501 is also rotated until the connecting rope 502 is loosened, at this time, the radial adjusting bolt 504d is no longer limited and fixed below the driving spring 504b, but is limited above the driving spring 504b in a blocking manner, that is, the driving spring 504b is switched from an idle state to a use state, at this time, the driving spring 504b is pressed downwards against the clamping annular groove 405, and the fixed circular shaft body 401 together with the whole cloth pressing roller can achieve elastic cloth pressing operation on the fabric, that is, a relatively large cloth pressing force can be naturally obtained when the thick fabric passes through, and a relatively small cloth pressing force is obtained when the thin fabric passes through, which is also a cloth pressing requirement commonly used in the bonding and compacting process of the composite fabric.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. These are non-inventive modifications, which are intended to be protected by patent laws within the scope of the claims appended hereto.
