Description

Technical Field

[0001] The utility model relates to the technical field of cord fabric production, in particular to a voice alarm device for a fabric storage rack. Background Art

[0002] During the production process of cord fabric, the winding part stops rotating when the roll is full, causing the rear cloth storage rack to rise to store cloth. The operator drops the cloth and changes the roll. Generally, the position information of the cloth storage rack is controlled by monitoring the number of turns of the lifting device winding chain.

[0003] However, during the production process, due to chain fatigue or disrepair of the equipment, it is very easy to cause the four-leg connection between the cloth storage rack and the upper truss to rise out of sync, causing the cloth storage rack to become unbalanced during operation, resulting in changes in the tension of the cord fabric and even equipment accidents. Utility Model Content

[0004] The utility model aims to provide a voice alarm device for a cloth storage rack.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] It includes an upper truss and a lower truss, and support columns are connected to the four corners of the upper truss and the lower truss. A cloth storage rack is slidably provided on the inner side wall of the support column. A driving device for driving the cloth storage rack to rise and fall is fixedly installed on the top wall of the upper truss. A number of rollers are fixedly provided between the cloth storage rack and the lower truss, and the rollers are sequentially passed through the upper and lower parts of the rollers. Infrared detection modules of a certain height are fixedly provided at the four corners of the cloth storage rack. A reflector matched with the infrared detection module is fixedly provided on the top wall of the upper truss. Infrared transmitters and infrared receivers are spaced apart on a side of the infrared detection module close to the reflector. An sound and light alarm matched with the infrared detection module is fixedly provided on the outer wall of the support column. The highest position of the infrared detection module is 50-60cm higher than the upper truss, the height of the reflector is 5-10cm, and the reflector is 15-30cm away from the infrared detection module.

[0007] By adopting the above technical solution, the equipment is equipped with a controller and an external power supply and a transformer. The infrared detection module exceeds a certain height of the upper truss. Before reaching the top, the infrared receiver at one end can cooperate with the reflector to receive the infrared rays emitted by the infrared transmitter. At this time, the controller starts the sound and light alarm for a quick early warning, warning the operator that the top is about to be reached. At the same time, the relative height changes of the four corners of the cloth storage rack can be understood according to the different activation sequences of the sound and light alarms in different parts. The corner where the sound and light alarm sounds first has the highest height, and the corner where the sound and light alarm sounds last has the lowest height. This is convenient for accurately positioning the balance state of the cloth storage rack during later maintenance, and for controlling the tension of the cloth storage rack on the cord fabric, thereby ensuring the production quality of the cord fabric.

[0008] Furthermore, the driving device includes a mounting plate fixedly arranged on the top wall of the upper truss, a pair of positioning plates fixedly arranged on both sides of the top wall of the mounting plate, a transmission shaft is limited and rotated on the positioning plate, a capstan is fixedly provided on both ends of the transmission shaft, a lifting chain is fixedly installed on the capstan, one end of the lifting chain is fixedly connected to the bottom wall of the upper truss, and the other end is fixedly connected to the capstan, a rotating shaft is fixedly provided on the outer walls of both sides of the cloth storage rack, the rotating shaft sleeve is provided with a gear plate that cooperates with the lifting chain, a first gear is fixedly provided on the middle part of the transmission shaft, a driving motor is fixedly provided on the top wall of the mounting plate, and the driving motor sleeve is provided with a second gear that meshes with the first gear.

[0009] By adopting the above technical solution, the driving motor is also connected to the controller and the power transformer. The controller controls the rotation of the driving motor, and the engagement of the first gear and the second gear drives the transmission shaft to rotate, thereby driving the lifting chain to be retracted and extended. The retraction and extension of the lifting chain cooperates with the rotation of the gear plate to accurately control the lifting height of the cloth storage rack, thereby achieving the effect of driving and controlling the lifting of the cloth storage rack.

[0010] Furthermore, a pair of limit columns are connected between the upper truss and the lower truss, and limit plates are extended from the outer walls of both sides of the cloth storage rack to engage with the limit columns for sliding. An indicator plate is connected to one end of the limit column close to the lower truss, and a scale column is extended from the bottom wall of the limit plate to slide through the indicator plate. The scale column is engraved with a number of scales along the length direction and distributed on both sides of the cloth storage rack.

[0011] By adopting the above technical solution, the limit column is matched with the limit plate, and the indicator plate is matched with the scale column, so that the cloth storage rack can be strictly limited to the left and right, ensuring that the cloth storage rack is stably raised along the predetermined track. At the same time, the setting of the scale column also makes it easy to quickly and conveniently read the height of the cloth storage rack, which is convenient for operators to judge the operating status of the equipment. In addition, the scale columns are distributed on both sides of the cloth storage rack. In the case that the cloth storage rack is offset to the left or right, the offset status of the cloth storage rack can be quickly judged by comparing the readings of the scale columns on both sides, which is convenient for positioning adjustment and maintenance of the cloth storage rack.

[0012] In summary, the beneficial technical effects of the present invention are:

[0013] 1. The infrared detection module, reflector and sound and light alarm are used to quickly warn the operator and help the operator understand the relative height changes of the four corners of the cloth storage rack;

[0014] 2. The drive motor, lifting chain and gear plate are used to achieve the effect of driving and controlling the lifting of the cloth storage rack;

[0015] 3. The limit column, limit plate, indicator plate and scale column are used to quickly and conveniently read the height of the cloth storage rack and compare the readings of the scale columns on both sides to quickly judge the offset state of the cloth storage rack.
