TECHNICAL FIELD
[0001] The utility model relates to fiber cloth processing technical field, concretely is a tension machine with the function of smoothing and preventing wrinkle. BACKGROUND
[0002] In the continuous processing production line of fiber cloth (especially chemical fiber fabric), the tension machine is the key equipment for maintaining the tension state of the cloth, ensuring the processing precision and the quality of finished products. Its core function is to apply controllable tension to the cloth through the roller group (usually composed of upper and lower fixed rollers and movable rollers) to eliminate slack and maintain stable transmission tension. The movable roller is usually driven by a servo motor or an air cylinder, and through the closed-loop feedback of the pressure sensor and the displacement control system, the real-time adjustment of the tension is realized to adapt to the processing needs of fiber cloth of different thickness and elastic modulus.
[0003] However, the tension machine in the prior art has the following technical defects in actual application: the fiber cloth often produces local wrinkles or bending deformation before entering the tension machine due to tension fluctuations, mechanical vibrations or elastic properties of the cloth in the previous process. Although the existing tension machine can meet the tensioning operation of various fiber cloths, it cannot effectively eliminate the wrinkles formed. These defects will be directly transmitted to the subsequent processing links (such as cutting, printing or hot pressing), resulting in problems such as increased defective product rate and non-standard surface flatness of finished products.

[0006] Preferably, a pair of sliding rods are fixedly connected to the outer wall of the rotating rod, and the sliding rods are slidingly connected with the soft sleeve through a sliding groove.
[0007] Preferably, the end of the soft sleeve close to the cavity plate is provided with an auxiliary assembly, the auxiliary assembly comprises a metal ring, the metal ring is fixed on the end surface of the soft sleeve close to the cavity plate, the metal ring is magnetically attracted by a magnetic ring away from the end surface of the metal ring, the end surface of the magnetic ring away from the metal ring is fixed with a sleeve ring, and the inner wall of the sleeve ring is fixedly connected with the outer wall of the rotating rod.
[0008] Preferably, the cavity plate is connected with the square rod through a connecting assembly, the connecting assembly comprises a pair of sleeve blocks, the pair of sleeve blocks are respectively sleeved on the outer wall of the square rod on both sides, the top ends of the pair of sleeve blocks are fixedly connected with the bottom ends of the pair of cavity plates respectively, the front surface of the sleeve block is threadedly connected with a bolt, and the outer wall of the square rod is provided with an anti-skid strip on the front side, and a portion of the bolt penetrating through the sleeve block abuts against the anti-skid strip.
[0009] Preferably, a storage box is installed below the front surface of the support.
[0010] Compared with the prior art, the tension machine with the smoothing and anti-wrinkle function has the following advantages:
[0011] Through the cooperation between the support, the fixed roller, the movable roller, the fiber cloth and the smoothing and anti-wrinkle assembly, before the fiber cloth is put into the fixed roller and the movable roller for tensioning operation, the fiber cloth is first fully opened and kept in a flat state, and the two sides of the fiber cloth protrude into the soft sleeves arranged above and below. Since the soft sleeve and the spiral protrusions thereon both have elastic deformation capability, the spiral protrusions can be in close contact with the surface of the fiber cloth and abut tightly. When the fiber cloth passes through the fixed roller and the movable roller and is put into the next process for uniform speed traction, the movable roller of the tension machine moves to implement tensioning operation on the fiber cloth, and at the same time, the two servo motors drive the rotating rod, the soft sleeve and the spiral protrusions to rotate (the output shafts of the two servo motors rotate synchronously, and the rotating speed is determined according to the traction moving speed of the fiber cloth). In this process, the spiral protrusions arranged above and below have opposite spiral directions, and they can both generate an acting force towards the cavity plate on the passing fiber cloth, thereby achieving the effect of opening and smoothing the passing fiber cloth. Since the wrinkles of the fiber cloth can be eliminated in advance, the defects are avoided from being transmitted to subsequent processing links (such as cutting, printing or hot pressing), thereby reducing the problems of cutting deviation, uneven printing ink penetration, hot pressing hollowing and layering caused by wrinkles, and improving the qualified rate of finished products after subsequent processing.
[0012] Through the coordinated operation of the rotating rod, slide bar, slide groove, soft sleeve, and spiral protrusion, before using the tensioning machine, the operator can select soft sleeves of different outer diameters according to the thickness of the fiber cloth to be processed, and put them on the outer wall of the rotating rod. This allows the spiral protrusions on the outer wall of the soft sleeve to press against the surface of the fiber cloth with a moderate force. During the process of putting the soft sleeve on the outer wall of the rotating rod, the slide bar will slide fully into the slide groove, which helps to improve the stability of the soft sleeve after it is put on the outer wall of the rotating rod, making it easier for the rotating rod to transmit the soft sleeve stably.
[0013] Through the coordinated operation of the rotating rod, soft sleeve, and auxiliary components, after the soft sleeve is fully fitted onto the outer wall of the rotating rod, the metal ring fixed to the end of the soft sleeve will fully contact the magnetic ring. Subsequently, the magnetic ring generates a magnetic attraction force on the metal ring. Since the magnetic ring is fixedly connected to the rotating rod through the collar, this can greatly improve the stability between the soft sleeve and the rotating rod after it is fitted.
[0014] Through the coordinated operation of the bracket, support rod, cavity plate, soft sleeve, spiral protrusion, square rod, and connecting components, before using the tensioning machine, the operator needs to turn the bolt counterclockwise to separate the bolt from the anti-slip strip set on the upper part of the square rod. At this time, the sleeve block can slide on the outer wall of the square rod, thereby adjusting the distance between the cavity plates set on both sides in the transverse direction, and then adjusting the distance between the two pairs of soft sleeves distributed in the transverse direction to adapt to fiber cloths of different widths. After determining the distance between the two cavity plates, turn the bolt clockwise to make it fully abut against the anti-slip strip. The operation is simple and convenient.

DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0023] Please refer to Figures 1-5 The present application provides a technical solution: a tension machine with a smoothing and wrinkle prevention function, comprising: a support 1, a fixed roller 2, a moving roller 3 and a fiber cloth 4, the front surface of the support 1 is provided with the fixed roller 2, the upper side of the fixed roller 2 is provided with the moving roller 3, the moving roller 3 is connected with the support 1 through a transmission mechanism, the outer wall of the fixed roller 2 and the moving roller 3 is respectively provided with the fiber cloth 4, and the upper side of one side of the support 1 is provided with a smoothing and wrinkle prevention assembly; the smoothing and wrinkle prevention assembly comprises: a pair of cavity plates 5, the pair of cavity plates 5 are located on the upper side of one side of the support 1, the lower side of the cavity plate 5 is connected with a square rod 6, the square rod 6 is fixedly connected with the support 1 through a support rod 7, the inside of the cavity plate 5 is provided with a pair of gears 8, the pair of gears 8 are meshed and connected, the inner wall of the gear 8 is fixedly connected with a rotating rod 9, the rotating rod 9 is rotatably connected with the cavity plate 5 through a ball bearing, the outer wall of the rotating rod 9 is provided with a soft sleeve 10, the outer wall of the soft sleeve 10 is provided with a spiral protrusion 11, the end of the rotating rod 9 away from the soft sleeve 10 is fixedly connected with a servo motor 13, and the shell of the servo motor 13 is fixedly connected with the cavity plate 5.
[0024] In the specific implementation process, it is particularly worth pointing out that the support 1 is made of high-strength metal material as the support body of the whole tension machine, has sufficient rigidity and stability, can withstand various forces generated by the fiber cloth 4 during processing, and ensures the normal operation of the whole equipment. The fixed roller 2 and the movable roller 3 are made of high-quality steel, and the surface is precisely machined and specially treated, which has high smoothness and wear resistance, can reduce the friction damage to the fiber cloth 4, and at the same time ensure the smooth running of the fiber cloth 4 on the roller. The transmission mechanism is a necessary component inside the tension machine, which is a known technical structure. It can ensure that the movable roller 3 moves at a predetermined speed and displacement, realizes accurate tension control of the fiber cloth 4, and the cavity plate 5 in the smoothing and anti-wrinkle assembly is an internal hollow structure, which provides space for the installation and operation of components such as gears 8 and rotating rods 9. The material is also selected from high-strength metal to ensure the stability of the structure. The soft sleeve 10 is made of materials with good elasticity and flexibility, such as rubber or silicone, which can adapt to the surface shape of the fiber cloth 4, ensure that the spiral protrusions 11 are in close contact with the surface of the fiber cloth 4, and the spiral directions of the spiral protrusions 11 distributed above and below are opposite, which can generate appropriate force during rotation to effectively smooth and prevent wrinkles of the fiber cloth 4. The servo motor 13 has high-precision speed control and torque output capability, which can adjust the rotation speed of the rotating rod 9 in real time according to the traction speed of the fiber cloth 4, and ensure the consistency of the smoothing and anti-wrinkle effect. In this application, the servo motor 13 is used as the power source of the rotating rod 9. Of course, the power source can also be replaced by other power sources that can apply power to the two bottom rotating rods 9 synchronously.
[0025] Further, the outer wall of the rotating rod 9 is fixedly connected with a pair of sliding strips 12, and the sliding strips 12 are slidably connected with the soft sleeve 10 through sliding grooves 21.
[0026] In the specific implementation process, it is particularly worth pointing out that the sliding strip 12 is made of the same metal material as the rotating rod 9, which is in the shape of a long strip, and the surface is smooth, and the rotating rod 9 is an integral molding structure. The sliding groove 21 is opened on the inner wall of the soft sleeve 10, which is matched with the sliding strip 12 in shape and size, and can ensure the smooth sliding of the sliding strip 12 in the sliding groove 21. The cooperation of the sliding strip 12 and the sliding groove 21 not only plays a role in sliding and limiting, but also prevents the soft sleeve 10 from moving axially relative to the rotating rod 9 during rotation, and also increases the friction between the soft sleeve 10 and the rotating rod 9 to some extent, so that the soft sleeve 10 can better follow the rotating rod 9 to rotate and improve the stability of the transmission.
[0027] Further, the end of the soft sleeve 10 close to the cavity plate 5 is provided with an auxiliary assembly, the auxiliary assembly comprises: a metal ring 14, the metal ring 14 is fixedly connected to the end face of the soft sleeve 10 close to the cavity plate 5, the end face of the metal ring 14 away from the soft sleeve 10 is magnetically attracted to a magnetic ring 15, the end face of the magnetic ring 15 away from the metal ring 14 is fixedly connected to a sleeve ring 16, the inner wall of the sleeve ring 16 is fixedly connected with the outer wall of the rotating rod 9.
[0028] In the specific implementation process, it is worth pointing out that the metal ring 14 is made of a metal material with good magnetism, such as iron or iron alloy, and its shape is a circular ring, which is fixedly connected with the end face of the soft sleeve 10 by adhesive bonding, ensuring the firm connection between the soft sleeve 10 and the metal ring 14. The magnetic ring 15 is also made of a material with strong magnetism, such as a neodymium iron boron magnet, and its shape and size are matched with the metal ring 14, which can generate a strong magnetic attraction force with the metal ring 14, so as to tightly attract the soft sleeve 10 to the magnetic ring 15. The sleeve ring 16 is made of the same metal material as the rotating rod 9, and is fixedly connected with the rotating rod 9 by welding, ensuring the stable and reliable connection between the sleeve ring 16 and the rotating rod 9. The design of the auxiliary assembly further enhances the connection stability between the soft sleeve 10 and the rotating rod 9 through magnetic attraction. During the operation of the tension machine, even if the soft sleeve 10 is subjected to a large external force, the magnetic attraction force between the metal ring 14 and the magnetic ring 15 can maintain the connection between the soft sleeve 10 and the rotating rod 9, preventing the soft sleeve 10 from falling off, thereby ensuring the normal operation of the entire flattening and wrinkle prevention assembly.
[0029] Further, the cavity plate 5 is connected with the square rod 6 through a connecting assembly, the connecting assembly comprises: a pair of sleeve blocks 17, the pair of sleeve blocks 17 are respectively sleeved on the outer wall of the square rod 6, the top ends of the pair of sleeve blocks 17 are respectively fixedly connected with the bottom ends of the pair of cavity plates 5, the front surface of the sleeve block 17 is threadedly connected with a bolt 18, the outer wall of the square rod 6 is provided with an anti-skid strip 20 on the front side, and the bolt 18 penetrates through a part of the sleeve block 17 and abuts against the anti-skid strip 20.
[0030] In the implementation process, it is particularly worth pointing out that the sleeve block 17 is made of high-strength metal material, and the inner wall is gap-fitted with the outer wall of the square rod 6. Gap-fitted means that there is a gap (including a minimum gap equal to zero). The top end of the sleeve block 17 is fixedly connected to the bottom end of the cavity plate 5 by welding, so that the cavity plate 5 can be firmly installed on the sleeve block 17. The anti-skid strip 20 is usually a certain roughness texture structure formed on the front side of the outer wall of the square rod 6 by machining process, such as knurling, grooving, etc., which can increase the friction between the bolt 18 and the square rod 6, and prevent the bolt 18 from loosening due to vibration during equipment operation. When it is necessary to adjust the distance between the cavity plates 5, only need to rotate the bolt 18 counterclockwise, so that the bolt 18 is separated from the anti-skid strip 20, and then move the position of the sleeve block 17 on the square rod 6, so as to adjust the distance between the cavity plates 5, and then adjust the distance between the two pairs of soft sleeves 10, so as to adapt to different widths of the fiber cloth 4. After the adjustment is completed, rotate the bolt 18 clockwise, so that it is fully in contact with the anti-skid strip 20, and fix the sleeve block 17 on the square rod 6, so as to ensure the stability of the position of the cavity plate 5. The design of this connecting assembly is simple and convenient to operate, has high adjustment accuracy, and can meet the processing needs of different specifications of fiber cloth.
[0031] Further, the storage box 22 is installed below the front surface of the support 1.
[0032] In the implementation process, it is particularly worth pointing out that the storage box 22 is made of hard plastic or metal material, which is in the shape of a cuboid and has a certain volume, and can be used to store some accessories, tools or spare parts related to the tension machine, such as different specifications of soft sleeves 10, bolts and nuts, lubricating oil, etc. In addition, the inside of the storage box 22 can also be provided with a partition structure, so as to classify and store different kinds of articles, improve the utilization rate of storage space and the convenience of article management, and provide a certain convenience for the workers.
[0033] Working principle:
[0034] Fiber cloth tensioning and smoothing and wrinkle prevention principle:
[0035] Initial tension and contact: before the fiber cloth 4 is put into the fixed roller 2 and the movable roller 3 for tensioning operation, the fiber cloth 4 is fully opened and kept flat, and the two sides of the fiber cloth 4 pass through the soft sleeves 10 arranged up and down, because the soft sleeves 10 and the spiral protrusions 11 thereon both have elastic deformation ability, the spiral protrusions 11 can be in close contact with the surface of the fiber cloth 4 and tightly abut, preparing for the subsequent smoothing and wrinkle prevention operation, when the fiber cloth 4 passes through the fixed roller 2 and the movable roller 3 and is put into the next process for uniform speed traction, the movable roller 3 of the tensioning machine moves to implement tensioning operation on the fiber cloth 4, ensuring that the fiber cloth 4 maintains appropriate tension during traction, avoiding the influence of insufficient or excessive tension on subsequent processing, at the same time, the two servo motors 13 drive the rotating rods 9, the soft sleeves 10 and the spiral protrusions 11 to rotate (the output shafts of the two servo motors 13 rotate synchronously, and the rotating speed is determined according to the traction moving speed of the fiber cloth 4), in this process, the spiral protrusions 11 arranged oppositely up and down have opposite spiral directions, and they can both generate a force towards the cavity plate 5 direction on the passing fiber cloth 4, which can effectively open and smooth the passing fiber cloth 4, and eliminate possible wrinkles on the fiber cloth 4 in advance, since the wrinkles are eliminated in advance, the defects are avoided to be transferred to the subsequent processing links (such as cutting, printing or hot pressing), thereby reducing the problems of cutting deviation, uneven printing ink penetration, hot pressing hollowing and layering caused by wrinkles, and significantly improving the qualified rate of finished products after subsequent processing.
[0036] Soft sleeve adaptation and stability principle:
[0037] Before the tensioning machine is used, the operator can select soft sleeves 10 with different outer diameters according to the thickness of the fiber cloth 4 to be processed, and then suitably sleeve the soft sleeves 10 on the outer wall of the rotating rod 9, so that the spiral protrusions 11 arranged on the outer wall of the soft sleeve 10 can abut on the surface of the fiber cloth 4 with moderate force, ensuring that good smoothing and wrinkle prevention effect can be achieved during processing of fiber cloths with different thicknesses, and in the process of sleeving the soft sleeve 10 on the outer wall of the rotating rod 9, the sliding bar 12 will be fully slid into the sliding groove 21, which helps to improve the stability of the soft sleeve 10 after being sleeved on the outer wall of the rotating rod 9, so that the soft sleeve 10 is not easy to deviate or loosen during rotation, and the rotating rod 9 can stably drive the soft sleeve 10, thereby ensuring that the spiral protrusions 11 can continuously and stably generate force on the fiber cloth 4.
[0038] Stability principle of connection between soft sleeve and rotating rod:
[0039] When the soft sleeve 10 is fully sleeved over the outer wall of the rotating rod 9, the metal ring 14 fixed at the end of the soft sleeve 10 will be fully in contact with the magnetic ring 15, and then the magnetic ring 15 will generate a magnetic attraction force on the metal ring 14, and since the magnetic ring 15 is fixedly connected to the rotating rod 9 through the sleeve ring 16, this magnetic attraction connection mode can greatly improve the stability between the soft sleeve 10 and the rotating rod 9 after the soft sleeve 10 is sleeved, prevent the soft sleeve 10 from being separated from the rotating rod 9 when rotating or subjected to external force, and ensure that the entire smoothing and wrinkle prevention assembly can normally and stably work.
[0040] Cavity plate distance adjustment principle:
[0041] Before the tension machine is used, the operator needs to rotate the bolt 18 counterclockwise to separate the bolt 18 from the anti-skid strip 20 arranged above the outer wall of the square rod 6, at this time, the sleeve block 17 can slide on the outer wall of the square rod 6, so as to adjust the distance between the two cavity plates 5 arranged on the transverse side, and then adjust the distance between the two pairs of soft sleeves 10 arranged on the transverse side, so that the fiber cloth 4 of different widths can be adapted, and it is ensured that the fiber cloth 4 can be fully smoothed when passing through the soft sleeve 10 and the spiral protrusion 11, after the distance between the two cavity plates 5 is determined, the bolt 18 is rotated clockwise to be fully in contact with the anti-skid strip 20, which is simple and convenient, and can ensure that the position of the cavity plate 5 is fixed, and provides protection for the stable processing of the fiber cloth.
[0042] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
