Description

Technical Field

[0001] This utility model relates to the field of tape processing technology, and in particular to an automatic feeding device for fleece tape roll cores. Background Technology

[0002] In the automotive manufacturing and finishing industries, felt-touch tape, as an indispensable high-performance composite material, plays a crucial role due to its unique structure. It typically consists of three parts: a surface layer of finely textured fibrous felt, a middle layer often composed of a slightly elastic substrate, and a bottom layer coated with a strong acrylic adhesive specifically designed for harsh automotive environments. This carefully crafted lamination structure not only effectively absorbs and dampens mechanical vibrations but also eliminates frictional noises between parts through its soft, felt surface. From concealed seams inside the dashboard to structural gaps between door panels and metal door panels, and even the wrapping of wiring harnesses throughout the vehicle body, felt-touch tape is used consistently. Its core mission is to comprehensively improve the vehicle's NVH (noise, vibration, and harshness) performance, eliminating the squeaking and clicking sounds that may arise from driving bumps, while filling gaps to prevent dust and noise intrusion, and even making the sound of closing doors more solid and resonant, thus creating a quiet, refined, and reliable driving experience in every detail.

[0003] However, to perfectly wind such a delicate material into a roll, a sturdy core is essential as a supporting framework. In current mainstream processing, automated equipment is commonly used to clamp and position the core. Pneumatic clamps need to accurately grasp the empty core and transfer it to the precise coordinates of the winding spindle. Existing clamps, whether with excessively high pressure settings or insufficient contact area between the clamping surface and the core leading to pressure concentration, can easily deform the hollow paper core, turning it from a perfect circle into an ellipse or even a more irregular polygon. This results in uneven support during subsequent high-speed winding, directly causing uneven winding of the velour tape, leading to quality problems such as "collapsed edges" or "bulges," which seriously affect product appearance and user experience. Utility Model Content

[0004] The purpose of this invention is to provide an automatic feeding device for velour tape roll cores, in order to solve the problems mentioned in the background art. Existing clamps, whether with excessively high pressure settings or insufficient contact area between the clamping surface and the roll core leading to concentrated pressure, easily deform hollow paper roll cores, turning them from perfect circles into ovals or even more irregular polygons. This results in uneven support during subsequent high-speed winding, directly causing uneven winding of the velour tape, leading to quality problems such as "collapsed edges" or "bulges," severely affecting product appearance and user experience.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for fleece tape roll cores, including a base frame, an adjustment structure on the base frame, and a fixing structure on the adjustment structure; The fixing structure includes a fixing plate, a fixing frame on the fixing plate, a threaded rod movably mounted on the fixing frame, a guide rod on the fixing frame, a movable frame movably mounted on the threaded rod and movably connected to the guide rod, a rotating arm movably mounted on the fixing frame, a transmission frame movably mounted on the rotating arm, a connecting frame movably mounted on the fixing frame and movably connected to the transmission frame, and a driving assembly on the fixing frame.

[0006] Preferably, the drive assembly includes a first pulley and a first motor. The first pulley is mounted on the threaded rod, the first motor is mounted on the fixed frame, the drive end of the first motor is provided with a second pulley, and the first pulley and the second pulley are provided with a transmission belt.

[0007] Preferably, the first motor is fixed to the mounting bracket by bolts, and a pair of guide rods are provided.

[0008] Preferably, the adjustment structure includes a support frame mounted on the base frame. A first toothed wheel is movably mounted on the support frame. A second motor is mounted on the support frame, and a second toothed wheel is mounted on the drive end of the second motor. A toothed belt is mounted on the first toothed wheel and the second toothed wheel. A guide rail is mounted on the support frame, and a slider is mounted on the guide rail. A connecting block is mounted on the slider and is connected to the toothed belt. A movable plate is mounted on the connecting block, and a placement rack is mounted on the movable plate.

[0009] Preferably, the guide rail is adapted to the slider, and the second motor is fixed to the support frame by bolts.

[0010] Preferably, the movable plate is provided with movable wheels, and the base frame is provided with support legs.

[0011] Preferably, the support frame is provided with reinforcing ribs, and the placement frame is provided with a protective layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This automatic feeding device for fleece tape roll cores, through a fixed structure, uses a first motor-driven belt transmission system to precisely control the rotation of the threaded rod, thereby driving the moving frame to perform stable linear motion along the guide rod. This motion is converted into the synchronous radial expansion of a pair of transmission frames through a linkage mechanism composed of a rotating arm and a transmission frame, enabling them to smoothly and evenly abut against the inner wall of the roll core. This inside-out fixing method can form a uniform radial support force without applying excessive concentrated stress, effectively avoiding the plastic deformation or surface damage of the roll core caused by excessive local pressure in traditional external clamping methods.

[0013] 2. This automatic feeding device for fleece tape roll cores, through a set adjustment structure, uses a second motor to drive a precision transmission system consisting of a toothed wheel and a toothed belt. This system efficiently and accurately converts rotational motion into linear motion of the connecting block. A guiding mechanism composed of a slider and a guide rail ensures smooth and error-free movement, thereby driving the moving plate and the roll core it carries for precise positioning and transport. This design automates and increases the efficiency of the roll core feeding process, significantly reducing the labor intensity and uncertainty of manual operation. Simultaneously, the toothed belt drive offers advantages such as accurate transmission ratio, low noise, and shock absorption, effectively reducing impact and vibration during movement. This ensures the stability and safety of the roll core during transport, preventing surface damage or positional deviation. It provides a reliable guarantee for the accurate positioning and efficient connection of the roll core on the winding spindle, greatly improving the production efficiency and operational reliability of the entire winding system.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: an automatic feeding device for fleece tape roll cores, including a base frame 1, an adjustment structure 3 on the base frame 1, and a fixing structure 2 on the adjustment structure 3; The fixing structure 2 includes a fixing plate 201, a fixing frame 202 on the fixing plate 201, a threaded rod 203 movably mounted on the fixing frame 202, a guide rod 204 on the fixing frame 202, a movable frame 205 movably mounted on the threaded rod 203 and movably connected to the guide rod 204, a rotating arm 206 movably mounted on the fixing frame 202, a transmission frame 207 movably mounted on the rotating arm 206, and a connecting frame 208 movably mounted on the fixing frame 202 and movably connected to the transmission frame 207. The fixed frame 202 is equipped with a drive assembly. The rotating arm 206, the transmission frame 207, and the connecting frame 208 are each provided in pairs and are arranged symmetrically. When it is necessary to fix the core, the rotating arm 206 enters the core, the threaded rod 203 rotates, and the moving frame 205 moves on the guide rod 204 under the action of the threaded rod 203. When the moving frame 205 moves, it can drive the rotating arm 206 to rotate. The rotating arm 206 can drive the transmission frame 207 to move. The connecting frame 208 can stabilize the movement of the transmission frame 207. The pair of transmission frames 207 abut against the inner arm of the core, thereby fixing the core and preventing deformation caused by clamping.

[0017] Furthermore, the drive assembly includes a first pulley 209 and a first motor 210. The first pulley 209 is mounted on the threaded rod 203, and the first motor 210 is mounted on the fixed frame 202. The drive end of the first motor 210 is provided with a second pulley 211. The first pulley 209 and the second pulley 211 are provided with a transmission belt 212 to drive the first motor 210. The first motor 210 can drive the second pulley 211 to rotate, and the transmission belt 212 drives the first pulley 209 to rotate under the action of the second pulley 211. The first pulley 209 can drive the threaded rod 203 to rotate on the fixed frame 202.

[0018] Furthermore, the first motor 210 is fixed to the fixed frame 202 by bolts. This rigid connection not only ensures that the first motor 210 can effectively resist torque reaction force and vibration load during operation, but its standardized installation interface design also provides great convenience for the pre-assembly, on-site debugging and subsequent maintenance of the equipment. The guide rod 204 is provided in pairs. This double rod structure provides the moving frame 205 with torsional and eccentric load resistance that exceeds that of a single rod structure, ensuring that its movement trajectory always maintains strict linearity, so that it can still achieve smooth and jam-free high-precision movement when subjected to asymmetrical loads.

[0019] Furthermore, the adjustment structure 3 includes a support frame 301, which is mounted on the base frame 1. A first toothed wheel 302 is movably mounted on the support frame 301. A second motor 303 is mounted on the support frame 301, and a second toothed wheel 304 is mounted on the driving end of the second motor 303. A toothed belt 305 is mounted on the first toothed wheel 302 and the second toothed wheel 304. A guide rail 306 is mounted on the support frame 301, and a slider 307 is mounted on the guide rail 306. A connecting block 308 is mounted on the slider 307 and is connected to the toothed belt 305. A movable plate 309 is provided on the 08, and a placement rack 311 is provided on the movable plate 309. A fixed plate 201 is installed on the movable plate 309. The core is placed on the placement rack 311. When the core needs to be sent to the winding spindle, the second motor 303 is driven. The second motor 303 can drive the second toothed wheel 304 to rotate. The toothed belt 305 moves under the action of the first toothed wheel 302 and the second toothed wheel 304. The toothed belt 305 can drive the connecting block 308 to move. The connecting block 308 can move on the guide rail 306 through the slider 307. The connecting block 308 can drive the movable plate 309 to move, thereby sending the core to the winding spindle.

[0020] Furthermore, the guide rail 306 is adapted to the slider 307. This adaptation relationship converts sliding friction into rolling friction through an internally integrated circulating ball or ball structure, thereby significantly reducing motion resistance and wear. This ensures that the slider 307 can maintain extremely high positioning accuracy, smooth operation, and long-term durability when it moves along the guide rail 306 for a long stroke. The second motor 303 is fixed to the support frame 301 by bolts. This connection method not only provides the motor with sufficient connection rigidity and vibration resistance, but its standardized installation interface design also enables the second motor 303 to achieve quick positioning and convenient disassembly and assembly during initial debugging or subsequent maintenance, significantly improving the efficiency of equipment assembly and maintenance.

[0021] Furthermore, the movable plate 309 is equipped with movable wheels 310, a pair of which are symmetrically arranged on the movable plate 309. This dual-wheel layout effectively distributes the total weight of the equipment, and the optimized wheel track design significantly improves the anti-tipping ability and overall stability of the movable plate 309 during straight-line travel and turning. At the same time, the wheel surface, made of high-performance materials such as polyurethane, has both load-bearing strength and ground protection function, ensuring that the equipment can achieve smooth and stable movement and precise positioning under various working conditions. The base frame 1 is equipped with support legs, which, by increasing the ground contact area and providing reliable rigid support, evenly transfer the working load of the equipment to the ground, thereby significantly enhancing the overall stability and vibration resistance of the base frame 1 during static operation.

[0022] Furthermore, the support frame 301 is provided with reinforcing ribs. These ribs, which have undergone topology optimization design, significantly improve the bending and torsional stiffness of the support frame 301 under dynamic load conditions by changing the force flow path and increasing the moment of inertia of the cross section. This ensures that it maintains excellent structural stability and dimensional accuracy as the core load-bearing component of the equipment during long-term use. The placement frame 311 is provided with a protective layer. The protective layer is located on the side wall of the placement frame 311 near the core and provides protection when the placement frame 311 supports the core.

[0023] Working principle: When the core is placed on the placement rack 311 and needs to be fixed, the rotating arm 206 enters the core, driving the first motor 210. The first motor 210 drives the second pulley 211 to rotate. The transmission belt 212, under the action of the second pulley 211, drives the first pulley 209 to rotate. The first pulley 209 drives the threaded rod 203 to rotate on the fixed frame 202. As the threaded rod 203 rotates, the moving frame 205 moves on the guide rod 204 under the action of the threaded rod 203. When the moving frame 205 moves, it drives the rotating arm 206 to rotate. The rotating arm 206 drives the transmission frame 207 to move, and so on. The connecting frame 208 can stabilize the movement of the transmission frame 207. A pair of transmission frames 207 abut against the inner arm of the core, thereby fixing the core and preventing deformation caused by clamping. When the core needs to be sent to the winding spindle, the second motor 303 is driven. The second motor 303 can drive the second toothed wheel 304 to rotate. The toothed belt 305 moves under the action of the first toothed wheel 302 and the second toothed wheel 304. The toothed belt 305 can drive the connecting block 308 to move. The connecting block 308 can move on the guide rail 306 through the slider 307. The connecting block 308 can drive the moving plate 309 to move, thereby sending the core to the winding spindle.
