Description

Technical Field

[0001] The invention relates to the technical field of textile tentering devices, in particular to a tentering device for producing special textile fabrics. Background Art

[0002] Textile fabrics need to be stretched during production because they are prone to shrinkage after going through multiple production processes. The stretching operation of textile fabrics can stretch and shape the textile fabrics to standard sizes through the stretching device, thereby ensuring the normal production and use of the textile fabrics.

[0003] However, as far as the current stretching device is concerned, it does not have a structure for adjusting the stretching force, so that when stretching, it can only stretch the textile fabric that matches the stretching force of the stretching device. Otherwise, the textile fabric will be over-stretched or the stretching degree will not meet the standard. The adaptability is poor, and the existing stretching device can only stretch a single piece of cloth, and cannot perform continuous stretching operations. It is impossible to perform continuous stretching operations on textile fabrics wrapped on cloth rollers. The work efficiency is low, the flexibility is poor, and the practicality is not high.

[0016] Optionally, the fixed sleeve block is symmetrically inserted into the interior of the cloth roller rotating cylinder, and a fixed threaded hole is provided inside the fixed sleeve block. Both ends of the rod body of the fixed rod are provided with threads, and the threads at both ends of the rod body of the fixed rod are in opposite directions.

[0017] Optionally, the bottom of the limit baffle is in a cross shape, and a baffle limit plate is inserted into the interior of the fixed base. Beneficial Effects

[0018] When the device is in use, the rotational resistance of the cloth roller rotating drum can be adjusted by the stretching force component, and the rotational resistance of the cloth roller rotating drum is the stretching force of the traction device pulling the textile cloth to be rolled up. The design of freely adjustable stretching force enables the device to adapt to different types of textile cloth for stretching operations, and the cloth roller rotating drum can rotate independently outside the positioning inner shaft, and the textile cloth wrapped on the cloth roller can be fixed on the outside of the cloth roller rotating drum by the cloth roller fixing component and rotate with the cloth roller rotating drum, so that the textile cloth wrapped on the cloth roller can be stretched continuously and evenly, thereby improving production quality and working efficiency by 30%, making the device extremely flexible, adaptable and practical.

[0019] In addition, the stretching force of the textile cloth can be adjusted by rotating the adjusting rod, so that the device can adapt to the stretching operation of textile cloths of different types and kinds. When the adjusting rod is rotated, the rod thread of the adjusting rod can drive the compression push plate to one side through the adjusting threaded hole to squeeze the damping top spring, so that the linkage block can pull the two damping friction blocks inward or push them outward through the synchronous connecting rod under the pressure of the damping top spring, thereby changing the contact pressure between the damping friction block and the damping friction disk, thereby changing the damping force of the rotation of the cloth roller rotating cylinder, that is, changing the stretching force when the textile cloth is stretched. It is flexible to use, easy to adjust and highly adaptable.

[0020] In addition, the device also has a protection function to avoid damage to the textile fabric during the stretching process. Since the damping top spring provides damping force for the rotating cylinder of the cloth roller, when jamming occurs during the stretching process, the damping friction block can reversely compress the damping top spring to avoid the rotation of the damping friction disk, so that the damping friction disk will not get stuck and fail to cause damage to the textile fabric, and it is stable to use.

[0021] In addition, the cloth roller rotating cylinder and the cloth roller fixing assembly of the device are an integral whole, and the cloth roller rotating cylinder can rotate freely outside the positioning inner shaft, so that the stretching force and the fixing of the cloth roller can be operated independently, and it is flexible to use. The cloth roller can be fixed to the outside of the cloth roller rotating cylinder through the cloth roller fixing assembly, and the cloth roller is sleeved on the outside of the cloth roller rotating cylinder. Then the fixing rod is rotated alone, and when the fixing rod rotates, the rod body thread drives the two fixed sleeves to move synchronously in opposite directions through the fixed threaded hole, and the fixed sleeve lifts the fixing plate upward through the fixed connecting rod to fix the cloth roller, thereby realizing the function of fixing the cloth roller to the outside of the cloth roller rotating cylinder to continuously stretch the textile cloth outside the cloth roller, and can continuously stretch the rolled textile cloth. It is easy to use and has strong adaptability.

[0022] In addition, when the cloth roller is fixed on the outside of the cloth roller rotating cylinder and rotates with the cloth roller rotating cylinder, the cloth roller rotating cylinder obtains rotational resistance through the stretching force component, so that when the textile cloth outside the cloth roller is wound up, the textile cloth can obtain the stretching force continuously, evenly and constantly, and the stretching processing quality of the textile cloth is greatly improved.
