Description

Technical Field

[0001] This utility model relates to a fabric storage rack device, which is a device used for fabric storage and tension adjustment during fabric processing. Background Technology

[0002] During fabric processing, the fabric needs to be stored in storage racks for later use. These racks are typically equipped with tension adjustment devices to regulate the fabric's tension.

[0003] Existing fabric storage rack tension adjustment mechanisms mostly use hydraulic drives or chain drives, which have problems such as complex structure, high maintenance costs, and insufficient tension control accuracy. In addition, hydraulic systems are prone to oil leaks, which can easily contaminate the fabric and cause environmental pollution, and require an additional hydraulic power source; chain drives are prone to wear and require regular lubrication, resulting in high failure rates and maintenance costs, which can easily affect production efficiency.

[0004] Therefore, there is an urgent need for a fabric storage rack device with a simplified structure and precise control. Utility Model Content

[0005] In view of the above-mentioned defects in the existing technology, the present invention provides a fabric storage rack device with a simple structure and capable of accurately controlling the tension of the fabric.

[0006] This utility model is achieved through the following technical solution: a fabric storage rack device, characterized in that it includes a fixed frame and a movable frame. The fixed frame includes a top frame, a bottom frame, and multiple vertical columns connected between the edges of the top and bottom frames. The movable frame is vertically mounted within the fixed frame via a screw drive device. Multiple rotatable rollers arranged in the same direction are provided on both the movable frame and the bottom frame, with the rollers on the movable frame and the bottom frame being staggered. The screw drive device includes a screw, a nut, and a screw drive mechanism. The screw is rotatably mounted vertically between the top and bottom frames and connected to the screw drive mechanism. The nut is fixed to the movable frame and threadedly engaged with the screw. A guide wheel is provided at the end of the movable frame, and the guide wheel engages with a guide groove provided on the column.

[0007] In operation, the fabric is sequentially wound around rollers on the bottom frame and the moving frame for storage. A screw drive mechanism raises and lowers the moving frame within the fixed frame, adjusting the fabric tension within the storage rack. During lifting and lowering, guide wheels move along guide grooves on the uprights, restricting the frame's rotational freedom and ensuring smooth lifting. By controlling the lifting speed and position of the moving frame via the screw drive mechanism, the fabric tension can be dynamically adjusted to ensure stability.

[0008] Furthermore, the screw drive device is powered by a servo motor or a stepper motor. A servo motor or stepper motor allows for precise control of the fabric tension and fabric storage, improving the adjustment accuracy and response speed of the fabric tension.

[0009] Furthermore, to ensure the reliability of the movement of the mobile frame, the lead screw includes multiple screws.

[0010] Furthermore, a rotatable auxiliary roller is provided on the outer side of the fixed frame, and the axis of the auxiliary roller is parallel to the axis of the roller shaft on the bottom frame. The auxiliary roller can guide and transition the fabric.

[0011] The beneficial effects of this utility model are as follows: This utility model uses a screw drive device to move the moving frame up and down to adjust the fabric tension, achieving millimeter-level lifting accuracy, ensuring stable fabric tension, and providing high control precision. Furthermore, the use of a screw drive device simplifies the equipment structure, reducing failure rate and equipment maintenance costs. This utility model uses a motor drive, resulting in low energy consumption, no oil pollution, and energy conservation and environmental protection. This utility model has a compact structure and precise control, making it suitable for fabric storage and transportation processes in the textile, dyeing, and other fields.

[0014] The present invention will be further described below through non-limiting embodiments and in conjunction with the accompanying drawings:

[0015] As shown in the attached diagram, a fabric storage rack device includes a fixed frame, a movable frame 4, and a screw drive device. The fixed frame includes a top frame 2, a bottom frame 3, and multiple columns 1. The columns 1 are vertically fixed to the ground, and their bottoms are supported by column mounting bases. Both the top frame 2 and the bottom frame 3 are rectangular frames made of steel profiles. Columns 1 are installed at the four corners and the middle edges of the frames of the top frame 2 and bottom frame 3, respectively. The top frame 2 is fixed to the top of the columns 1, and the bottom frame 3 is fixed to the bottom of the columns 1 at a certain distance from the ground. The movable frame 4 is also a rectangular frame and is vertically and flexibly mounted within the fixed frame via the screw drive device, located between the top frame 2 and the bottom frame 3. Both the movable frame 2 and the bottom frame 3 are equipped with multiple rotatable rollers 5 arranged in the same direction, and the rollers on the movable frame 4 and the rollers on the bottom frame 3 are staggered. The screw drive device includes a screw 7, a nut 8, and a screw drive mechanism. The screw 7 is rotatably and vertically mounted between the top frame 2 and the bottom frame 3 and connected to the screw drive mechanism. A fixed seat 10 is provided on the bottom frame 3, and the lower end of the screw 7 is mounted on the fixed seat 10. The nut 8 is fixed to the movable frame 4 and threadedly engaged with the screw 7. The screw 7 can be driven to rotate by the screw drive mechanism, and when the screw 7 rotates, the movable frame 4 can be raised and lowered through the nut 8. A guide wheel 9 is provided at the end of the movable frame 4, and the guide wheel 9 engages with a guide groove provided on the column 1. When the movable frame 4 is raised and lowered, the guide wheel 9 can move along the guide groove on the column 1. The guide groove on the column 1 restricts the rotational freedom of the movable frame 4, ensuring that the movable frame 4 rises and falls smoothly. A rotatable auxiliary roller 11 is provided on the outside of the fixed frame. The axis of the auxiliary roller 11 is parallel to the axis of the roller shaft 5 on the bottom frame 3. The auxiliary roller 11 can guide and transition the fabric.

[0016] In this invention, the lead screw drive mechanism can employ various existing drive mechanisms capable of driving the lead screw 7 to rotate, such as direct motor drive, motor drive via a reducer, or motor drive via belt transmission. For ease of control of the lead screw drive device, it is preferable that the power source for the lead screw drive device is a servo motor or a stepper motor. In this embodiment, it is preferable to use a motor 6 to drive the lead screw 7. The motor 6 is fixed on the mounting base 10, and the output shaft of the motor 6 is connected to the drive end of the lead screw 7 via a coupling. The motor 6 is either a servo motor or a stepper motor.

[0017] In this invention, there can be one or more lead screws 7. To ensure reliable lifting and lowering of the moving frame 4, it is preferable that there are multiple lead screws 7, for example, symmetrically arranged at the middle of the left and right ends of the moving frame 4 and / or symmetrically arranged at the middle of the front and rear ends of the moving frame 4. The multiple lead screws 7 can be driven independently by a motor, or multiple lead screws can be driven by a single motor using a belt drive mechanism, or multiple lead screws can be driven by a single motor using a synchronization mechanism, etc.

[0018] In operation, the fabric is guided into the fixed frame by the auxiliary roller 11, and then passes sequentially around the rollers 5 of the bottom frame 3 and the movable frame 4 to achieve folding and storage of the fabric. When the production line speed changes, the controller adjusts the speed of the motor 6 in real time, driving the movable frame 4 to rise and fall to compensate for differences in fabric length and maintain constant tension. For example, when unwinding accelerates, the movable frame 4 rises to store excess fabric; when rewinding accelerates, the movable frame 4 falls to release the fabric, preventing breakage or loosening.

[0019] The control component in this invention is existing technology.

[0020] This utility model has a compact structure and can achieve millimeter-level lifting accuracy through the cooperation of a servo motor and a lead screw, which can accurately control the tension and storage amount of the fabric.

[0021] The other parts in this embodiment are all existing technologies and will not be described in detail here.
