Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cord dipping processing, and in particular to a device for balancing the tension of a dipped cord. Background Art
[0002] The cord is mainly used as a reinforcing material for rubber products such as tires, conveyor belts, and transmission belts. The cord needs to be dipped in glue, specifically, the cord passes through a glue immersion tank to soak the cord in glue.
[0003] At present, there are only a handful of equipment specifically used for single-wire cord dipping, and the way the equipment retracts and releases the cord during the dipping process is too complicated. The cord will undergo multiple steps for dipping during the entire operation. Since the travel and swing distance of each cord during operation is inconsistent, the tension of the dipped cord is poor, resulting in relative deviations between the amount of dipping and the degree of heat treatment of each cord, resulting in unstable performance of the tested product.
[0004] In the related art, there are tension adjustment devices for cords. One part is an electronic tensioner that controls the winding tension. It is controlled by a microcircuit board during the dipping process to make the tension of a single cord uniform. However, this design has the disadvantages of occupying too much space, making it difficult to achieve balanced control of multiple cords at the same time, difficult maintenance, and high CNC cost. Another part is a device that balances the tension of the dipped cord. The device mainly uses a threaded rod to cross the frame structure, and the tension adjusting pulley is screwed to the threaded rod through a thread. However, there are phenomena such as loose nuts and deformation of the threaded rod during operation. Since there is no standard tension correction device, it is easy to have problems with the matching of tension adjustment of multiple groups of cords during operation, which will cause excessive tension deviation between cords in different positions, which is easy to cause product quality problems. At the same time, the tension correction method relies entirely on personal feeling and technique. The tension correction of multiple cords requires continuous installation and testing, and the correction time is relatively long.
[0005] Therefore, how to avoid the unstable performance of the dipped cord product due to uneven tension and jumping of multiple cords during the skeleton cord dipping process is a technical problem that technical personnel in this field currently need to solve. Utility Model Content

[0015] In some embodiments, three anti-jump wire devices are provided, and the three anti-jump wire devices are respectively connected to the first row of hinge points, the second row of hinge points, and the third row of hinge points;
[0016] Among them, the number of anti-jump devices on the second row hinge points is the same as the number of anti-jump devices on the third row hinge points, and the number of anti-jump devices on the first row hinge points is greater than the number of anti-jump devices on the second row hinge points.

[0025] With respect to the above-mentioned background technology, the device for balancing the tension of the dipped cord provided in the embodiment of the present application includes an outer frame and a plurality of tension adjustment modules arranged on the outer frame, and any tension adjustment module includes a support frame, a scissor-type adjustment frame, at least two anti-jumping devices and a telescopic drive assembly. Among them, the support frame is fixed to the outer frame, and both ends of the scissor-type adjustment frame can be slidably connected to the support frame so that the scissor-type adjustment frame can extend and contract. Each anti-jumping device is arranged on the scissor-type adjustment frame in parallel with each other, and each anti-jumping device includes a guide rod and a plurality of anti-jumping devices arranged on the guide rod at intervals. The guide rod and each anti-jumping device are connected to the scissor-type adjustment frame, and each anti-jumping device can slide along the axial direction of the guide rod.

[0029] Secondly, compared with the traditional setting method of manually rotating the pulley on the threaded steel rod to adjust the spacing between the pulleys, the present application adopts a telescopic drive assembly to provide a telescopic drive force to enable the scissors-type adjustment frame to extend and contract relative to the support frame, thereby driving the anti-jumping device in each anti-jumping device to slide synchronously relative to the corresponding guide rod, and the spacing between each anti-jumping device is adjusted evenly and stably.

[0031] Fourthly, compared with the traditional setting method of using an electronic tensioner to control the tension of a single cord, the device used in this application to balance the tension of the dipped cord avoids the use of an electronic control system and a tension sensor, and can simultaneously achieve tension control of multiple cords.

DETAILED DESCRIPTION
[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0042] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0043] It should be noted that the directional words such as "upper end, lower end, left side, right side" described below are all defined based on the drawings in the specification.
[0044] Please refer to Figures 1 to 5, Figure 1 is a schematic diagram of the wiring of the device for balancing the tension of the dipped cord in the embodiment of the present application; Figure 2 is a front view of Figure 1; Figure 3 is a structural schematic diagram of the tension adjustment module in the device for balancing the tension of the dipped cord shown in Figure 1; Figure 4 is a structural schematic diagram of the tension adjustment module in the device for balancing the tension of the dipped cord shown in Figure 1 from another angle; Figure 5 is a structural schematic diagram of the anti-jump device in the tension adjustment module shown in Figure 3.
[0045] The device for balancing the tension of the rubber-dipped cord provided in the embodiment of the present application includes an outer frame 10 and a plurality of tension adjustment modules 20 arranged on the outer frame 10, and any tension adjustment module 20 includes a support frame 21, a scissors-type adjustment frame 22, at least two anti-jump wire devices 23 and a telescopic drive assembly 24.
[0046] The support frame 21 is fixed to the outer frame 10 , and is used to support the scissor-type adjustment frame 22 and various anti-jump wire devices 23 provided on the scissor-type adjustment frame 22 .
[0047] Both ends of the scissor-type adjustment frame 22 can be slidably connected to the support frame 21 so that the scissor-type adjustment frame 22 can extend and contract.
[0048] Each anti-jumping device 23 is arranged on the scissors-type adjustment frame 22 in parallel with each other. Each anti-jumping device 23 includes a guide rod 231 and a plurality of anti-jumping devices 232 arranged at intervals on the guide rod 231. The guide rod 231 and each anti-jumping device 232 are connected to the scissors-type adjustment frame 22, and each anti-jumping device 232 can slide along the axial direction of the guide rod 231. The anti-jumping device 232 is used for cord winding and for preventing the cord from loosening.
[0049] Two ends of the telescopic driving assembly 24 are respectively connected to two ends of the scissor-type adjustment frame 22 to drive the two ends of the scissor-type adjustment frame 22 to slide relative to the support frame 21 .
[0050] In this way, under the action of the telescopic driving power of the telescopic driving assembly 24, the two ends of the scissors-type adjusting frame 22 slide relative to the supporting frame 21, so that the scissors-type adjusting frame 22 can extend and contract relative to the supporting frame 21. As the scissors-type adjusting frame 22 extends and contracts, the anti-jumping devices 232 in each anti-jumping device 23 can be driven to slide synchronously relative to the corresponding guide rod 231, so as to achieve the purpose of adjusting the distance between the anti-jumping devices 232.
[0051] Compared with the traditional threaded steel rod setting method which is easy to bend and deform under the force of the pulley, the present application adopts a scissor-type adjustment frame 22, which not only provides stable support to ensure the relative position stability of each anti-jump device 232, but also can synchronously adjust the spacing of multiple groups of anti-jump devices 232 during the simultaneous dipping of multiple cords, effectively shortening the tension correction time between different cords and saving processing preparation time and maintenance time.
[0052] Compared with the traditional setting method of manually rotating the pulley on the threaded steel rod to adjust the spacing between the pulleys, the present application adopts a telescopic drive assembly 24 to provide a telescopic drive force to enable the scissor-type adjustment frame 22 to extend and contract relative to the support frame 21, thereby driving the anti-jump wire device 232 in each anti-jump wire device 23 to synchronously slide relative to the corresponding guide rod 231, and the spacing between each anti-jump wire device 232 is adjusted evenly and stably.
[0053] Compared with the traditional setting method in which the tension of the cord fluctuates during the pay-off process, which may cause the cord to deviate from its track in severe cases, the present application adopts an anti-jumping device 23, which provides cord winding through an anti-jumping device 232 and can prevent the cord from loosening. It can effectively prevent the cord from deviating from its predetermined position during high-speed operation, thereby ensuring the tension of the cord during processing.
[0054] Compared with the traditional setting method of using an electronic tensioner to control the tension of a single cord, the device used in this application to balance the tension of the dipped cord avoids the use of an electronic control system and a tension sensor, and can simultaneously achieve tension control of multiple cords. It is simple and convenient to operate, easy to maintain and repair, and has low production costs.
[0055] In summary, the device for balancing the tension of the dipped cord adopted in the present application solves the problem of unstable performance of the dipped cord product due to uneven tension and jumping of multiple cords when the skeleton cord passes through the wire pay-off frame and the dipping tank during the dipping process of the skeleton cord. The cords include but are not limited to nylon, polyester, aramid, polyester, rayon, carbon fiber, etc.
[0056] In some embodiments, the support frame 21 includes two relatively arranged slide rails 211, and slide plates 25 are provided at both ends of the scissor-type adjustment frame 22. The two ends of the slide plates 25 are respectively slidably connected to the two slide rails 211, and the two ends of the telescopic drive assembly 24 are respectively connected to the two slide plates 25 to drive the two slide plates 25 to slide relative to the support frame 21.
[0057] Both slide rails 211 extend in the horizontal direction as shown in FIG. 3 , and the length of the slide plates 25 at both ends of the scissor-type adjustment frame 22 is adapted to the spacing between the two slide rails 211 , so that the slide plates 25 at both ends of the scissor-type adjustment frame 22 can slide along the extension direction of the slide rails 211 to realize the extension and retraction movement of the scissor-type adjustment frame 22 .
[0058] Specifically, when the extending end of the telescopic drive assembly 24 makes an extending movement, the two slide plates 25 slide in opposite directions, causing the scissors-type adjusting frame 22 to extend, thereby increasing the distance between each anti-jumping device 232 in each anti-jumping device 23; when the extending end of the telescopic drive assembly 24 makes a retracting movement, the two slide plates 25 slide toward each other, causing the scissors-type adjusting frame 22 to retract, thereby reducing the distance between each anti-jumping device 232 in each anti-jumping device 23.
[0059] In some embodiments, both ends of the two slide rails 211 are provided with limit blocks 212 , and the limit blocks 212 are used to contact and abut against the corresponding slide plates 25 to limit the corresponding slide plates 25 from sliding off the two slide rails 211 .
[0060] In some embodiments, the scissor-type adjustment frame 22 includes a first adjustment frame body 221 and a second adjustment frame body 222. The first adjustment frame body 221 includes a plurality of first adjustment arms, and any two adjacent first adjustment arms are hinged by a pin. Similarly, the second adjustment frame body 222 includes a plurality of second adjustment arms, and any two adjacent second adjustment arms are hinged by a pin.
[0061] It should be noted that the number of first adjustment arms in the first adjustment frame body 221 and the number of second adjustment arms in the second adjustment frame body 222 are the same, and correspond one to one, and the crossing positions are hinged together by pins, so that a first row of hinge points 223, a second row of hinge points 224 and a third row of hinge points 225 can be formed along the structure shown in Figure 3, and the second row of hinge points 224 and the third row of hinge points 225 are respectively located on the upper and lower sides of the first row of hinge points 223.
[0062] The structure of the scissor-type adjustment frame 22 ensures that each supporting point is sufficient to bear the bearing capacity of each anti-jump wire device 232, thereby reducing the downward pressure deformation of the entire mechanism and minimizing damage to the device.
[0063] In this embodiment, three anti-jump wire devices 23 are provided, and the three anti-jump wire devices 23 are respectively connected to the first row hinge point 223, the second row hinge point 224, and the third row hinge point 225. Among them, the number of anti-jump wire devices 232 on the second row hinge point 224 is the same as the number of anti-jump wire devices 232 on the third row hinge point 225, and the number of anti-jump wire devices 232 on the first row hinge point 223 is greater than the number of anti-jump wire devices 232 on the second row hinge point 224.
[0064] Specifically, the first row of hinge points 223 has ten hinge points, and correspondingly, the number of anti-jump devices 232 of the anti-jump device 23 arranged on the first row of hinge points 223 is ten, and the ten anti-jump devices 232 are connected to the ten cross hinge points one by one. In this way, when the scissor-type adjustment frame 22 is expanded and retracted, the spacing between the ten anti-jump devices 232 of the anti-jump device 23 on the first row of hinge points 223 can be synchronously adjusted; the second row of hinge points 224 has eleven hinge points, and the anti-jump devices 23 of the anti-jump device 23 arranged on the second row of hinge points 224 There are five anti-jump devices 232, and the five anti-jump devices 232 are connected to five hinge points at intervals of one hinge point. The hinge points between any two adjacent anti-jump devices 232 (four in total) are connected to the corresponding guide rods 231. In this way, when the scissors-type adjustment frame 22 is expanded and retracted, the distances between the five anti-jump devices 232 of the anti-jump device 23 on the second row hinge point 224 can be synchronously adjusted; the connection method of the anti-jump device 23 on the third row hinge point 225 refers to the connection method of the anti-jump device 23 on the second row hinge point 224.
[0065] It should be emphasized that, according to the winding needs of the cord, the anti-jump devices 232 on the first row of hinge points 223, the anti-jump devices 232 on the second row of hinge points 224 and the anti-jump devices 232 on the third row of hinge points 225 are staggered in the vertical direction as shown in Figure 3. For example, taking the anti-jump devices 232 on the first row of hinge points 223 as a reference, the five anti-jump devices 232 on the second row of hinge points 224 are respectively connected to the first, third, fifth, seventh and ninth hinge points from the left in the second row of hinge points 224, and the five anti-jump devices 232 on the third row of hinge points 225 are respectively connected to the second, fourth, sixth, eighth and tenth hinge points from the left in the third row of hinge points 225.
[0066] In some embodiments, the wire jump prevention device 232 includes a housing 2321 , a pulley 2322 , and a limiting bead 2323 .
[0067] Among them, the shell 2321 is provided with an opening, and the pulley 2322 is rotatably connected to the rotating groove inside the shell 2321. The pulley 2322 is provided with a limiting groove 23221. The limiting groove 23221 is used for winding the cord and for limiting the deviation of the cord along the axial direction of the pulley 2322. The limiting bead 2323 is provided in the opening, and the limiting bead 2323 is used to limit the cord from detaching from the pulley 2322.
[0068] Specifically, the pulley 2322 is made of a ceramic wheel and is super-polished, and is equipped with a high-speed bearing 2325, so that the vibration during winding is within a very small range, thereby maintaining the stability of the cord tension during winding.
[0069] In this way, considering that the tension of the conventional cord fluctuates during the pay-off process, which may cause the cord to deviate from its track in severe cases, the anti-jump device 232 of this embodiment can effectively prevent the cord from deviating from its predetermined position during high-speed operation, and the low-resistance pulley 2322 can reduce the friction between the cord and the surface of the pulley 2322, thereby reducing the tension loss of the aramid cord during the processing process to a certain extent.
[0070] In some embodiments, gaskets 2324 are provided on both sides of the shell 2321 along the axial direction, and the anti-jump device 232 is connected to the scissor-type adjustment frame 22 through the two gaskets 2324 .
[0071] In this embodiment, each gasket 2324 has a portion extending upward or downward, so that each gasket 2324 can be connected to the hinge point of the scissor-type adjustment frame 22 through the portion extending upward or downward.
[0072] It can be seen that the gasket 2324 not only serves to connect the anti-jump device 232 and the hinge point of the scissor-type adjustment frame 22, but also protects the shell 2321 on both sides of the shell 2321, so that when the corresponding catheter passes through the anti-jump device 232, the pulley 2322 inside the shell 2321 can be protected.
[0073] In some embodiments, the number of tension adjustment modules 20 is set to two groups, and the two groups of tension adjustment modules 20 are staggered in the vertical direction.
[0074] To this end, the outer frame 10 includes a first installation frame 11 and a second installation frame 12 . The first installation frame 11 and the second installation frame 12 are parallel to each other, and two sets of tension adjustment modules 20 are respectively installed on the first installation frame 11 and the second installation frame 12 .
[0075] In this embodiment, the number of tension adjustment modules 20 in any group of tension adjustment modules 20 is three, the three tension adjustment modules 20 of the first group of tension adjustment modules 20 are installed on the first installation frame 11 at the same spacing, and the three tension adjustment modules 20 of the second group of tension adjustment modules 20 are installed on the second installation frame 12 at the same spacing.
[0076] The three tension adjustment modules 20 on the first installation frame 11 and the three tension adjustment modules 20 on the second installation frame 12 are staggered in the vertical direction, specifically, in the vertical direction as shown in FIG. 2, the three tension adjustment modules 20 on the first installation frame 11 and the three tension adjustment modules 20 on the second installation frame 12 are not simply aligned up and down, but have a certain interval or offset between each other, forming a staggered layout. In this way, the cord can be wound successively through the first tension adjustment module 20 on the second installation frame 12, the first tension adjustment module 20 on the first installation frame 11, the second tension adjustment module 20 on the second installation frame 12, the second tension adjustment module 20 on the first installation frame 11, the third tension adjustment module 20 on the second installation frame 12, and the third tension adjustment module 20 on the first installation frame 11, and then pass through the device.
[0077] In addition, the outer frame 10 further includes four legs 13, which are used to support the first installation frame 11 and the second installation frame 12. The lengths of the four legs 13 can be adjusted by screwing, and each leg 13 is provided with a universal wheel with a brake.
[0078] To summarize, the present application provides a device for balancing the tension of the rubber-impregnated cord, and the operation process includes: passing the cord through the ultra-low resistance pulley on each support point in turn, and checking the corresponding anti-jump device 23 to ensure that the cord arrangement order is consistent; braking the universal wheel at the bottom of the outer frame 10, inserting the rebound fixing bolt, and adjusting the spacing of the radial anti-jump device 232; applying pre-tension to the cord, fine-tuning the spacing of the anti-jump device 232, observing whether the cord is pulled smoothly, avoiding cord kinking and shaking, and taking the feeling of uniform resistance as the best point; after adjusting the position of the entire device, tighten and straighten the cord.
[0079] In this way, through the flexibly rotatable pulley 2322 and the anti-jump wire device 23, an adjustable pulley 2322 array is designed to meet the processing requirements of different cords. The entire device is located on a height-adjustable outer frame 10. The frame can not only move freely through the universal wheels with brakes, but also can be fixed by limit columns to ensure the overall firmness of the device. The device can effectively balance the cord tension, straighten the cord direction, avoid kinking and shaking, and make the cord pay out smoothly, thereby improving the operating efficiency of the dipping machine and the product qualification rate.
[0080] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
[0081] The above is a detailed introduction to the device for balancing the tension of the dipped cord provided by the present application. This article uses specific examples to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the scheme and core ideas of the present application.
