Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of cloth extension equipment, and specifically to a sanitary product conveyor. BACKGROUND

[0002] Some raw materials of sanitary products may shrink during the early processing. For example, some sanitary cloths are composed of multiple layers of materials, such as a surface layer, an absorption layer, a bottom layer, etc. To ensure that the edges of the layers of materials are neat and the widths are matched after compounding, and to avoid product quality problems (such as delamination, leakage, etc.) caused by a layer being too narrow or too wide, the widths of the layers of materials need to be extended during the conveying process so that they reach appropriate and consistent widths before compounding to prevent shrinkage and deformation after compounding.

[0003] For example, the prior art "Cloth extension device of mask production machine" (Publication No. CN214827750U) sets an extension mechanism on the conveying line of mask cloth, which is composed of a connecting rod and a smoothing roller. The connecting rod is driven by a motor and a screw structure to control the force of the smoothing roller on the cloth for smoothing and extending the cloth. However, the prior art still has the following technical problems:

[0004] In the prior art, the extension of the width is achieved by the pressing force of the smoothing roller on the cloth. The outer surface of the smoothing roller is relatively smooth, and it cannot completely ensure that the cloth is completely extended during the pressing process, which may result in the width of the produced product not meeting the design standard and may cause quality problems such as uneven extension of the cloth and uneven surface. SUMMARY

[0005] The utility model provides a sanitary product conveyor, which can solve the problem of uneven extension of the cloth and uneven surface in the prior art.

[0006] The present application provides the following technical solution: a sanitary product conveyor, comprising a rack and an extension mechanism arranged on the rack, wherein the extension mechanism comprises a roller shaft assembly, a belt assembly wound around the roller shaft assembly, and an adsorption assembly fixed on the rack; the belt assembly comprises an outer belt, a middle belt, and an inner belt arranged on the roller shaft assembly at a certain interval, the outer belt, the middle belt, and the inner belt are provided with a plurality of through holes, and the outer belt and the inner belt away from the middle belt are provided with protrusions.

[0007] Advantages:

[0008] 1. Strengthen the effect of extension. The protrusions arranged on the outer side belt and the inner side belt away from the middle belt side can exert additional pulling force on the cloth edge during the operation of the belt. This targeted design helps to stretch the cloth edge, making the extension of the cloth in the width direction more sufficient, especially for the edge part which is prone to insufficient extension, ensuring the uniformity of the size of the entire cloth in the width direction.

[0009] 2. Strengthen the reliability. The multiple through holes arranged on the outer side belt, the middle belt and the inner side belt work cooperatively with the adsorption assembly fixed on the rack. The adsorption assembly generates adsorption force which can tightly adhere the cloth to the belt through the through holes, preventing the cloth from shifting, sliding or wrinkling during the conveying and extension process. This adsorption fixing method can ensure the accurate position of the cloth on the belt, making the extension operation more stable and reliable, effectively improving the consistency and quality stability of the product.

[0010] Further, the adsorption assembly includes an air suction box fixed on the rack, and the air suction box is connected with a negative pressure fan through a pipeline.

[0011] Beneficial effect: The negative pressure fan is connected with the air suction box through the pipeline, which can quickly extract the air in the air suction box to form a negative pressure environment. This powerful negative pressure can tightly adsorb the cloth of the sanitary product through the through holes on the belt, ensuring that the cloth is tightly adhered to the belt during the conveying and extension process, greatly reducing the problems of cloth sliding and deviation, and providing a strong guarantee for accurate cloth extension and stable conveying.

[0012] Further, the roller shaft assembly includes a driving roller shaft arranged on the rack, a tensioning roller shaft arranged on the rack, and multiple driven roller shafts arranged on the air suction box. The outer side belt, the middle belt and the inner side belt are arranged around the outer periphery of the driving roller shaft and the driven roller shaft, and the tensioning roller shaft is tightly pressed against the outer side belt, the middle belt and the inner side belt.

[0013] Beneficial effect: The driving roller shaft provides power for the belt assembly, ensuring that the cloth of the sanitary product can be continuously and stably conveyed on the conveyor; it ensures the uniform motion of the cloth during the conveying process, avoids problems such as cloth wrinkling and uneven extension caused by speed fluctuations, and helps to improve product quality and production efficiency; the tensioning roller shaft tightens the belt assembly, which can change the tension of the belt to prevent the belt assembly from slipping.

[0014] Further, the rack is also fixed with a belt limiting assembly, which includes a mounting shaft fixed on the rack, a support block fixedly connected to the mounting shaft, and a limiting rod rotatably connected to the support block. The belt limiting assembly is provided with multiple limiting rods, and the outer side belt, the middle belt and the inner side belt are located between adjacent limiting rods.

[0015] Beneficial effects: By distributing multiple belt limiting components along the belt running direction, adjacent limiting rods confine the outer, middle, and inner belts to specific positions. During conveyor operation, this effectively prevents lateral belt deviation, ensuring the belt always runs stably along the predetermined trajectory. This guarantees that the fabric receives uniform and stable tension in the width direction, thereby achieving precise stretching and improving the dimensional consistency and product quality of hygiene product fabrics.

[0016] Furthermore, the support block is provided with a mounting hole and a notch communicating with the mounting hole. The mounting shaft passes through the mounting hole, and a screw is also connected to the support block. The screw passes vertically through the notch to lock the mounting shaft.

[0017] Beneficial effects: The mounting holes provide a precise positioning reference for the mounting shaft, allowing it to quickly and accurately penetrate the support block. This positioning method reduces alignment time during installation and improves equipment assembly efficiency. When the screws are tightened, they compress the notch, firmly fixing the mounting shaft within the mounting holes and effectively preventing axial movement of the shaft during equipment operation.
