Description
TECHNICAL FIELD
[0001] The present application relates to the field of building material manufacturing, and in particular to a winding device for waterproofing membrane. BACKGROUND
[0002] In the field of building waterproofing engineering, the production and use of waterproofing membrane are huge. With the development of the industry, the requirements for the winding quality of waterproofing membrane are also increasingly high. Traditional waterproofing membrane winding devices are often simple in structure and can only realize basic winding functions, lacking effective control means for the tension of the membrane.
[0003] In the early winding process, due to the absence of precise tension adjusting mechanisms, the membrane is prone to relaxation or excessive tensioning during winding. Relaxed membrane will lead to loose winding, which is easy to spread out during storage and transportation, affecting the quality and use convenience of the membrane; while excessive tensioning may cause the membrane to stretch and deform, damaging the physical properties of the membrane and reducing its waterproof effect and service life.
[0004] In addition, with the improvement of production efficiency, the winding speed is also correspondingly accelerated, which further aggravates the difficulty of membrane tension control. Traditional devices cannot adjust the tension of the membrane in time during high-speed winding, making it difficult to guarantee the winding quality of the membrane, resulting in a high scrap rate, increasing production costs and resource waste.
[0005] At the same time, during the winding process, the running stability of the membrane is also an important problem. Lack of effective auxiliary support and guiding devices, the membrane is prone to deviation, which not only affects the neatness of winding, but also may cause friction and collision between the membrane and other components, causing scratches and damage to the surface of the membrane, further affecting the product quality.
[0006] In view of the above related technologies, the inventors found that the following defects exist: many existing devices cannot maintain stable tension during winding. This is because they lack effective tension feedback and adjusting mechanisms. For example, during the initial and near-end stages of winding, the diameter of the membrane changes greatly, and the tension also changes accordingly, but existing devices may not be able to automatically adjust, resulting in significant differences in tension at different stages. This unstable tension will cause the membrane to be loose or tight, seriously affecting the quality of the membrane. CONTENT OF THE UTILITY MODEL

[0028] It needs to be further explained that: the adjusting seat 404 is the basic supporting part of the whole adjusting assembly, and the material thereof is selected from high-strength metal materials, such as carbon steel after quenching and tempering, so as to ensure that various stresses and impact forces generated in the coiled material tension adjusting process can be borne, and the stability and reliability of the whole adjusting mechanism are guaranteed. The connection between the adjusting seat 404 and the protruding block 405 adopts a welding process, and after strict welding quality detection, the strength and sealing property of the connection part are guaranteed, so as to prevent loosening or fracture in the long-term use process. The positioning groove 406 on the protruding block 405 has extremely high machining precision, and the width and depth tolerances thereof are controlled within an extremely small range, generally ±0.05mm, so as to ensure that the rotating rod 408 can smoothly and accurately rotate therein, and at the same time, the rotating angle of the rotating block 407 can be accurately limited, and the accuracy and consistency of the coiled material tension adjustment are guaranteed. The connections among the rotating block 407, the rotating rod 408, the connecting block 409 and the extension rod 410 all adopt a tight mechanical connection mode, such as a combination of pin connection and screw connection, so as to ensure the connection strength, realize effective force transmission, ensure that the rotation of the rotating block 407 can accurately drive the subsequent component to act, and then realize fine adjustment of the coiled material tension. The internal thread of the internally-threaded block 411 adopts a high-precision thread machining process, such as grinding, so that the cooperation gap between the internally-threaded block 411 and the bidirectional screw rod 412 is controlled within an extremely small range, generally 0.02-0.05mm, so that when the bidirectional screw rod 412 rotates, the internally-threaded block 411 can quickly, stably and accurately respond to drive the whole adjusting assembly to adjust the tension, avoid the occurrence of jamming or crawling phenomenon, and improve the sensitivity and precision of the tension adjustment.
[0029] Please refer to Figures 2 to 4The coiled material tension adjusting mechanism 4 further comprises a first tension component 401, a second tension component 402 and a connecting frame 403, the first tension component 401 is fixedly installed on the top of the rack 1, one side of the first tension component 401 is fixedly connected with the connecting frame 403, one side of the connecting frame 403 is fixedly installed with the second tension component 402.
[0030] Please refer to Figures 2 to 4 The coiled material tension adjusting mechanism 4 further comprises a bidirectional screw rod 412, a cross beam 413, a base 414, a servo motor 415, a positioning seat 416, a driving gear 417, a first driven gear 418 and a second driven gear 419, the bidirectional screw rod 412 is threadedly sleeved on one side of the inner threaded block 411, the cross beam 413 is fixedly installed on the top of the adjusting seat 404, one side of the cross beam 413 is fixedly installed with the base 414, the top of the base 414 is fixedly installed with the servo motor 415, one side of the servo motor 415 is fixedly connected with the positioning seat 416, the output end of the servo motor 415 is fixedly connected with the driving gear 417 after penetrating through the positioning seat 416, the bottom of the driving gear 417 is meshingly driven with the first driven gear 418, and the bottom of the first driven gear 418 is meshingly driven with the second driven gear 419.
[0031] It needs to be further explained that: the surface material of the tension roller in the first tension assembly 401 and the second tension assembly 402 is selected from rubber materials with high elasticity, high friction coefficient and wear resistance, such as nitrile rubber. This material can provide sufficient friction when in contact with the coiled material, ensuring that a stable and uniform tension is applied to the coiled material, while not causing scratches or wear to the surface of the coiled material. The roller core of the tension roller is made of high-strength alloy steel, such as 45 steel, and is subjected to quenching and tempering treatment to ensure that it has sufficient rigidity and strength to prevent bending and deformation during long-term stress. The structural design of the connecting frame 403 adopts a triangular or trapezoidal frame structure, which has good stability and carrying capacity, can effectively connect the first tension assembly 401 and the second tension assembly 402 into a whole, and evenly distribute the tension on the coiled material. The two ends of the bidirectional screw rod 412 are supported by high-precision bearings, such as angular contact ball bearings, which can withstand combined axial and radial loads to ensure the stability and precision of the bidirectional screw rod 412 during rotation, avoiding axial runout or radial runout, thereby ensuring accurate adjustment of the tension on the coiled material. The tooth profile of the driving gear 417, the first driven gear 418 and the second driven gear 419 adopts an involute tooth profile, which has good transmission stability and carrying capacity, ensuring efficient and stable power transmission between gears. The modulus and number of teeth of the gear are accurately calculated and selected according to the required transmission ratio and torque to ensure that the gear does not overload or fatigue during operation. At the same time, the meshing clearance between the gears is controlled between 0.1-0.3mm, and the center distance of the gears is adjusted and the appropriate tooth side clearance elimination method is used, such as gasket adjustment method and eccentric sleeve adjustment method, to ensure the stability and transmission accuracy of the gears during meshing, reducing noise and vibration during gear transmission.
[0032] Please refer to Figures 2 to 4 , the second driven gear 419 is fixedly sleeved on one side of the bidirectional screw rod 412, and the first driven gear 418 is movably installed on the clamping groove of the cross beam 413 through the rotating shaft.
[0033] The bidirectional screw rod 412 is arranged directly above the waterproof coiled material body 3, and the adapter block 409 is movably connected with the auxiliary supporting roller 5 through a bearing.
[0034] The rotating rod 408 is movably installed in the inside of the positioning groove 406, and the rotating block 407 is movably installed in the inside of the adjusting seat 404 through the rotating rod 408.
[0035] The first tension assembly 401 and the second tension assembly 402 each include two tension rollers arranged at the top and bottom of the waterproof coiled material body 3.
[0036] It needs to be further explained that: the second driven gear 419 and the fixed sleeve of the bidirectional screw rod 412 are connected by a combination of key connection and interference fit. The key connection can transmit larger torque to ensure the synchronous rotation between the second driven gear 419 and the bidirectional screw rod 412, while the interference fit can further enhance the tightness and reliability of the connection to prevent loosening or slipping during operation. During installation, precise heating or cooling process is used to achieve the interference fit between the second driven gear 419 and the bidirectional screw rod 412, ensuring the quality and precision of the connection. The shaft of the first driven gear 418 and the clamping groove of the cross beam 413 adopt clearance fit, with a clearance generally controlled between 0.05-0.1mm. This can ensure the flexible rotation of the shaft in the clamping groove, and also limit the shaft in radial and axial directions to prevent the first driven gear 418 from shifting or shaking during rotation, ensuring the stability and precision of gear transmission. At the same time, lubricating oil grooves and oil holes are provided in the clamping groove to lubricate the shaft well, reduce friction and wear, and prolong the service life of the shaft and the first driven gear 418. The bidirectional screw rod 412 is arranged directly above the waterproof roll body 3. This layout can make the linear motion of the internal threaded block 411 directly act on each component of the roll tension adjusting mechanism 4, reducing force transmission loss and direction deviation, and improving the response speed and precision of tension adjustment. At the same time, a protective cover is provided above the bidirectional screw rod 412 to prevent dust, debris and other foreign matter from entering the mating part of the screw rod and the internal threaded block 411, affecting the transmission precision and normal operation of the equipment.
[0037] The implementation principle of the winding device for waterproof roll material according to an embodiment of the present application is as follows:
[0038] Winding process: the winding mechanism drives the winding roller to rotate. Since the winding roller and the waterproof roll body are connected by belt transmission, the rotation of the winding roller will drive the waterproof roll body to wind. In this process, the roll tension adjusting mechanism adjusts the tension of the waterproof roll body to ensure the quality of winding.
[0039] Roll tension adjusting principle:
[0040] Preliminary tension adjustment of tension assembly: the upper and lower tension rollers in the first and second tension assemblies are arranged at the top and bottom of the waterproof roll body respectively. When the waterproof roll body passes through these tension rollers during winding, the tension rollers will exert a certain pressure on the roll to maintain a certain tension of the roll, thereby preliminarily adjusting the roll tension.
[0041] The first adjusting assembly and the second adjusting assembly in the roll material tension adjusting mechanism are symmetrically arranged with the waterproof roll body as the center. After the servo motor is started, the output end drives the driving gear to rotate, the driving gear meshes with the first driven gear to drive, the first driven gear meshes with the second driven gear to drive, thereby driving the bidirectional screw rod to rotate. Since the bidirectional screw rod is threadedly connected to the inner threaded block, the rotation of the bidirectional screw rod will make the inner threaded block move on the screw rod. The inner threaded block is connected to the rotating block through the extension rod, and the rotating block is movably installed on the convex block of the adjusting seat through the rotating rod, so that the movement of the inner threaded block will drive the rotating block to rotate around the rotating rod, thereby making the auxiliary supporting roller move up and down to change the supporting height and angle of the auxiliary supporting roller to the waterproof roll body, and accurately adjust the tension of the roll material.
[0042] Auxiliary supporting principle
[0043] The auxiliary supporting roller is connected to the rotating block through the rotating block and can move up and down and adjust the angle under the action of the roll material tension adjusting mechanism, and its main function is to provide additional support for the waterproof roll body during the winding process to prevent the roll material from deforming, wrinkling or running off due to its own gravity or tension during the winding process, and ensure that the roll material can be smoothly and uniformly wound onto the winding roller.
[0044] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
