Description
Technical Field
The utility model relates to a transmission device for splicing unidirectional cloth by strips, in particular to a synchronous transmission device.
Background
Unidirectional fabric refers to a woven fabric having a large number of woven or untwisted rovings in one direction (usually the warp direction, but also the fill direction) and no yarns, or only a small number and usually fine yarns, in the other direction, with the full strength of the fabric in one direction.
There are three main types:
1. the woven unidirectional cloth is generally warp unidirectional cloth and is mainly used for seismic restoration and reinforcement of building bridges, such as unidirectional carbon fiber cloth.
2. The fabric is mainly used in the aerospace industry and the ship industry, and is also used for building reinforcement and sports equipment.
3. The weftless unidirectional cloth is actually a prepreg sheet, and is formed by arranging fibers orderly in one direction by using special equipment, then crossly laying 2 layers or more of unidirectional cloth at 0-degree 90 degrees, and bonding the unidirectional cloth by using resin, or compounding a layer of film or release paper or even fiber grids, and is mainly used for sports equipment, such as golf clubs, fishing rods and the like, and is also used for bulletproof fields, wherein the main raw materials are aramid fibers, ultrahigh molecular weight polyethylene and the like.
The unidirectional cloth used for the product has the following characteristics:
the damping structure has good damping effect, small expansion coefficient, light skeleton and small deformation, and is widely applied to the aviation industry, such as a radome, an electronic equipment cabin, an engine shell, an engine blade, a cabin door, a blade of a helicopter and the like; the marine industry, such as sailing boats, yachts, deep sea fish boats, lifeboats, etc.; for sporting goods such as fishing poles, skis, hockey sticks, and the like; the device is used for chemical industry, such as a three-dimensional horizontal storage tank, a pipeline, a workbench and the like; for use in the medical industry, such as splints, bandages, respirators, and the like; the material is used for military industry, such as protective armor, large-caliber artillery, tank loading wheels and the like; other industries, such as reinforced prefabricated parts for construction, sword bars for sword bar looms, sword belts, etc. The organic fiber reinforced resin composite material is mostly applied to the bulletproof field, and weftless unidirectional cloth is adopted, so that the performance of the material is favorably exerted, and ballistic impact is dispersed and consumed most effectively. At present, aramid fiber materials and ultra-high molecular weight polyethylene materials are mainly used. The ultra-high molecular weight polyethylene material applied to the bulletproof field mainly has two forms, one is in a fiber form, and the other is in a strip form. The production process of the fiber unidirectional cloth mainly comprises the processes of filament spreading, surface treatment, gum dipping, drying and the like. The ultra-high molecular weight polyethylene strip has a two-dimensional physical form, is limited to the current production process level, is difficult to directly obtain a wide (such as a width larger than 500 mm) strip, needs to be spliced to produce a strip unidirectional fabric, and is used in the field of bulletproof.
The narrow ultra-high molecular weight polyethylene strip needs to be glued on one surface of the narrow ultra-high molecular weight polyethylene strip after being spliced and widened, so that the surface of the unidirectional fabric is covered with a glue film, the unidirectional fabric layers can be tightly combined in the subsequent hot pressing step, and the subsequent forming process and the product performance design can be completed. The unidirectional cloth coated with the adhesive needs to be dried, the ultrahigh molecular weight polyethylene unidirectional cloth is used for conveying materials in a production workshop through a multi-stage driving roller and a driven roller, when the materials are dried by using a traditional oven, gaps or overlapping can appear between the strips in the transverse direction (namely the width direction), and the gaps or overlapping are defects which cause adverse effects on the quality of the unidirectional cloth.
In order to avoid the above defects, a conveyor belt or a conveyor roller is usually arranged in the oven to serve as a transmission device to transmit the strip, so as to provide a certain supporting force for the strip, however, when the conveyor belt is used for transmission, due to poor air permeability of the conveyor belt, the air fluidity in the oven is poor, the drying efficiency is low, and the conveyor belt is often made of flexible materials, so that sufficient supporting force cannot be provided for unidirectional cloth, and the phenomenon that the unidirectional cloth is gapped or overlapped is poor is avoided; when using the transfer roller to carry, because one-way cloth can drive the transfer roller rotation in-process of marcing, the glue solution on one-way cloth is advancing the in-process and is flowing into the contact surface of one-way cloth and transfer roller from the gap between the strip easily for the transfer roller sticks together with the strip, very easily causes the strip to divide silk winding roller, needs equipment to shut down when taking place winding roller and gets into the oven by operation workman and handle, takes place danger easily and has seriously influenced production efficiency.
In order to solve the above problems, a novel transmission device is needed to solve the problem that the tapes of the ultra-high molecular weight polyethylene unidirectional fabric are easy to shift in the equipment such as an oven, and further the unidirectional fabric has gaps or overlaps.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems mentioned above, the utility model provides a strip splicing unidirectional fabric transmission device which can avoid unidirectional fabric gaps or overlapping caused by the deviation of strips in the transmission process.
For convenience of description, unless otherwise specified, the tape refers to a narrow-width unidirectional fabric material before splicing, such as a tape-shaped film or a bundle yarn, and the unidirectional fabric refers to a wide-width unidirectional fabric after splicing. The specific scheme provided by the utility model is as follows:
the strip splicing unidirectional cloth transmission device is characterized by comprising transmission rods arranged at intervals, wherein the maximum deformation amount of the transmission rods in the transmission process in the direction perpendicular to the axial direction of the transmission rods is smaller than 1mm, the transmission device is driven by a driving motor, unidirectional cloth is transmitted by a unidirectional cloth driving device, and the stepping speed of the transmission device is set to be consistent with the transmission speed of the unidirectional cloth.
Compared with the prior art, the transmission rods arranged at intervals are used as the material transmission device for splicing the unidirectional cloth into the strips, and the transmission rods are spaced at a certain distance, so that the air permeability is good, and the air flow in the oven is ensured to be consistent with the air pressure on the upper surface and the lower surface of the strips; the transmission rod only moves in the advancing direction of the unidirectional cloth and does not rotate, so that the phenomenon that the unidirectional cloth strips are divided into threads and wound on the rollers is avoided.
The deformation amount of the transmission rod in the direction perpendicular to the axial direction of the transmission rod is limited within 10mm, preferably within 5mm, more preferably within 2mm, and more preferably within 1mm, so that the position deviation of the strip caused by the deformation of the transmission rod can be avoided, and the defects of gaps or overlapping and the like on the unidirectional cloth are further avoided. This is because in the material transmission device of the stripe-spliced unidirectional fabric, if the transmission rod is bent and deformed in the transmission process, the transmission rod has an inclination angle in the horizontal direction to cause the stripe to slide or cause different support forces to the unidirectional fabric at different positions in the length direction on the transmission rod, so that the tension force applied to each stripe in the unidirectional fabric is uneven, the position of a part of the stripe in the unidirectional fabric is deviated, and further the unidirectional fabric is cracked or overlapped, and therefore the transmission device of the stripe-spliced unidirectional fabric has a high requirement on the dimensional stability of the transmission rod.
The transmission device and the unidirectional cloth adopt different power sources and make the traveling speeds of the transmission device and the unidirectional cloth consistent so as to avoid the strip position deviation caused by the fact that the transmission rod pulls the unidirectional cloth. Because the unidirectional cloth is formed by splicing the strips, if a conventional mode that the transmission device drives the material to advance is adopted, the contact surfaces of the transmission rod and the unidirectional cloth cannot be completely attached, so that the relative traction force of each point of the transmission rod to the unidirectional cloth is different, the tension of each strip in the unidirectional cloth is uneven, and further the unidirectional cloth is gapped or overlapped. Therefore, synchronous transmission is adopted, namely the unidirectional cloth is driven to advance by an independent driving device, the transmission device is driven to advance by the driving motor, the stepping speed of the transmission device is set to be consistent with the transmission speed of the unidirectional cloth, so that no relative motion exists between the transmission device and the unidirectional cloth, the transmission device only plays a supporting role on the unidirectional cloth, and in the advancing process of the unidirectional cloth, each strip has no tension difference in the advancing direction, and the gap or overlapping defect caused by different pulling forces of the transmission rod on the unidirectional cloth is avoided.
Optionally, the maximum deformation of the transmission rod in the direction perpendicular to the axial direction of the transmission rod during transmission is less than 5mm, preferably less than 2mm, and more preferably less than 1 mm.
Or, one-way cloth transmission of strip concatenation, including driving motor, its characterized in that still includes drive chain, transmission includes on the route of travel along the transfer line and the support sprocket that drive chain interval set up, adjacent two it is provided with spacing slide to support to fix between the sprocket, two adjacent support sprocket between the drive chain set up in the spacing slide
Optionally, the length of the single transmission rod is greater than 1 m.
Optionally, a transmission rod supporting device is arranged below the transmission rod.
When the length of the transmission rod is too large, the deformation degree of the transmission rod is increased due to factors such as material weight and self weight, and when the requirement on the shape and position stability of the transmission rod is accurate, the transmission rod supporting device can be additionally arranged below the transmission rod so as to improve the system stability and play a role in avoiding the transmission rod from deforming in the direction perpendicular to the axial direction.
Optionally, the transmission rod supporting device comprises a transmission rod supporting roller and a transmission rod supporting wheel, the transmission rod supporting roller is arranged below the transmission rod, the transmission rod supporting wheel is arranged on the transmission rod supporting roller and is concentric with the transmission rod supporting roller, and the excircle of the transmission rod supporting wheel is in contact with the transmission rod to support the transmission rod. One or more support wheels can be arranged on the support roller of the transmission rod according to the requirement, so that the support force of the support wheel to the transmission rod is provided, and the bending deformation of the transmission rod in the direction vertical to the axial direction of the transmission rod due to gravity can be avoided.
Optionally, the distance between the transmission rods is 5-500mm, preferably 50-300mm, more preferably 100-250 mm.
If the distance between the transmission rods is too short, the effect of improving the air permeability of the transmission device is not obvious, and if the distance between the transmission rods is too long, the support density of the transmission rods on the unidirectional cloth is too small, the support force on the unidirectional cloth is insufficient, and the tension on each strip is easy to be uneven, so that the proper distance between the transmission rods can play a role of enabling the tension on each strip to be even.
Optionally, the diameter of the drive rod is 10-50mm, preferably 15-40mm, more preferably 20-30 mm.
Optionally, the density of the material of the transmission rod is not higher than 2500kg/m3The bending strength is not less than 100MPa, preferably not less than 150MPa, and the bending modulus is not less than 30GPa, preferably not less than 50GPa, more preferably not less than 80 GPa.
Because one-way cloth is pieced together wide by the narrowband and is formed, one-way cloth breadth is great usually, and the length of drive rod needs to be greater than the width of one-way cloth, therefore the length of single drive rod is usually longer, when using conventional metal material, can be because metal material density is great for the metal pole is because dead weight is crooked. Therefore, in order to avoid the deformation of the transmission rod in the direction perpendicular to the axial direction due to the self-weight, the material of the transmission rod should have a low density and a high flexural strength and modulus. The lower density can make the dead weight of the transmission rod smaller, reduce the deformation of the transmission rod, the higher bending strength and the higher bending modulus can make the deformation degree of the transmission rod smaller when being stressed, and the deformation of the transmission rod can be reduced under the combined action of the lower density and the higher bending strength and the higher bending modulus, so that the tension on each strip of the unidirectional fabric is relatively uniform. In the solution according to the utility model, the definition of the material density and the modulus of elasticity thus jointly act to prevent a positional deviation of the strips in the unidirectional fabric.
Optionally, the drive rod is hollow.
The hollow transmission rod can further reduce the dead weight of the transmission rod under the condition that the bending strength of the transmission rod meets the requirement, the transmission rod is prevented from being bent due to overlarge dead weight, the deformation degree of the transmission rod in the direction perpendicular to the axial direction is further reduced, and the hollow transmission rod can also play a role in preventing the strips in the unidirectional cloth from being deviated or overlapped.

Preferred friction-increasing materials may be rubber, silicone rubber, and the like.
Optionally, the contact surface of the transmission rod and the unidirectional cloth is provided with an anti-adhesion coating and a material for increasing friction force. In practical application, the coating and the structure thereof can be set according to requirements, the anti-adhesion coating and the friction force increasing material can be arranged on the contact surface at intervals along the axial direction or the radial direction of the transmission rod, and the anti-adhesion coating and the point-shaped friction force increasing material can also be arranged on the contact surface.
Because the anti-adhesion coating is generally low in friction coefficient and is easy to cause relative sliding between the one-way cloth and the transmission rod, the anti-adhesion coating and the friction increasing material are arranged simultaneously, so that the transmission rod and the one-way cloth can be prevented from being adhered and simultaneously prevented from sliding relatively.

The box body 30 is provided with a plurality of box doors 38 at both sides, so that workers can handle and overhaul equipment when the unidirectional cloth 20 is dried and the adhesion of the strips 21 and the slipping of the transmission chain 4 occur, and the number of the box doors 38 can be flexibly set according to the length of the drying working section and the spatial distribution of the workshop. Door 38 may also be provided with a viewing window for viewing the operating conditions inside cabinet 30 when door 38 is closed. The box 38 is provided with heat and sound insulating material 34 inside the wall, which can save energy and reduce noise in the workshop to a certain extent.
The gas circulation device 40 includes a blower motor 41, a blower duct 42, a suction duct 43, a suction motor 44, and a gas heating device 45, and an air volume control system, a temperature control system, and a humidity control system, which are not shown in the drawings. The air supply motor 41 is connected to the air supply outlet 33 on the box 30 through an air supply duct 42, the air outlet on the box 30 is connected to the air exhaust motor 44 through an air exhaust duct 43, and the gas heating device 45 is selectively disposed inside or outside the box 30, in this embodiment, the gas heating device is disposed outside the box 30 at a position close to the air suction port of the air supply motor 41.
When the oven of the embodiment works, the unidirectional fabric 20 coated with the glue solution is conveyed to the transmission rod 5 of the transmission device 10 from an upstream device, and under the support of the transmission rod 5, the transmission rod 5 and the unidirectional fabric 20 synchronously advance to enter the oven body 30 through the material inlet 31 of the oven. In the oven box 30, the unidirectional fabric 20 travels along a preset arc-shaped travel route, in the travel process, the air supply motor 41 supplies the air flow heated by the air heating device 45 into the oven box 30 from the air supply outlet 33 of the oven box 30 through the air supply pipeline 42, the heated air is uniformly dispersed in the oven box 30 through the air distribution device 35 and is applied to the unidirectional fabric 20, and the glue solution on the unidirectional fabric 20 is dried. Meanwhile, the dried gas is taken away by the suction motor 44 along the suction duct 43 through the air outlet of the box 30. The dried unidirectional fabric 20 leaves the oven from the material outlet 32 under the support of the transmission rod 5 and enters the next process.
In the oven of the embodiment, the unidirectional fabric 20 and the transmission rod 5 synchronously move, and the transmission rod 5 only supports the unidirectional fabric, so that the air permeability of the transmission device can be increased, and meanwhile, the strips 21 are prevented from being divided and wound on the rollers; and the transmission rod 5 is made of carbon fiber, because the thermal expansion coefficient of the carbon fiber is small, the density is low, and the rigidity is large, the deformation is not easy to occur in the synchronous transmission of the wide-width material, such as the unidirectional cloth 20, the supporting performance of the material is uniform and stable, the tension balance of each strip 21 can be effectively maintained, and the position deviation of the strips 21 in the unidirectional cloth 20 is avoided. The air outlet side section 36 of the air distribution device in the drying oven is attached to the arc-shaped travelling route of the unidirectional cloth 20, so that air flow applied to the unidirectional cloth is more uniform, and the tension change caused by uneven air flow resistance of the strip in the whole travelling route is avoided while the drying effect is improved.
