Description

Technical Field

[0001] This utility model relates to the field of disposable hygiene product manufacturing technology, and in particular to a hygiene product manufacturing apparatus. Background Technology

[0002] Many disposable hygiene products incorporate product cutting devices during manufacturing. Manufacturers use specialized equipment to cut the products. Currently, product cutting mostly employs independent molds for continuous cutting and separation. While this achieves the desired cutting effect, its cutting characteristics have drawbacks:

[0003] 1. The long distance between the cut assembly and the sealing point, and the large positional deviation, result in a high rate of defective product cutting and product waste.

[0004] Second, the distance between the product edge and the sealing point after cutting is too long, resulting in a smaller actual product size and low material utilization.

[0005] Third, the cut edges are unsightly.

[0006] Therefore, a new product cutting device and manufacturing process are needed, which not only aims to solve the problem of defective product cutting,

[0007] Most importantly, it can improve material utilization and enhance the aesthetics of the product. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cutting device for hygiene products.

[0009] The technical solution of this utility model is: a cutting device for sanitary products, comprising a product input unit, a sealing and cutting unit, a transfer unit, and a product output unit; the product input unit is used to feed continuous products into the sealing and cutting unit; the sealing and cutting unit is used to seal and cut the continuous products fed from the product input unit; the transfer unit is used to transfer the cut products to the product output unit; and the product output unit is used to send out the cut products.

[0010] The product input unit is a conveyor roller.

[0011] The sealing and slitting unit includes a slitting roller and sealing and slitting heads evenly distributed circumferentially on the slitting roller; each sealing and slitting head is equipped with an independent drive assembly for welding and slitting movements; the slitting roller has a vacuum chamber inside, and its surface is densely covered with adsorption holes communicating with the vacuum chamber; the vacuum chamber is connected to a vacuum pumping device.

[0012] The transfer unit includes an adsorption transfer roller, a first guide roller, and a first tensioning roller; the adsorption transfer roller and the first guide roller are driven by a first belt; the first tensioning roller is used to tension the first belt between the adsorption transfer roller and the first guide roller; the product output unit is located above the first belt and forms a conveying channel with the first belt.

[0013] The product output unit includes a traction roller, a second tension roller, and two second guide rollers. The traction roller and the two second guide rollers are arranged in a triangle, and the traction roller and the two second guide rollers are driven by a second belt (4-4). The second tension roller is used to tension the second belt (4-4). The second belt (4-4) is arranged parallel to the first belt, and the conveying channel is formed by the gap between the second belt (4-4) and the first belt.

[0014] Both the first belt and the second belt (4-4) are densely covered with through holes.

[0015] The above technical solution has the following beneficial effects: (1) The sealing and cutting unit set in this utility model can complete the sealing and cutting action of the product at the same position, thereby forming a small cutting edge distance. It does not need to be transported to the back end after sealing and then cut. This not only solves the problem of poor cutting of the product, but also improves the material utilization rate. At the same time, it can realize fully automatic production with high production efficiency.

[0016] (2) The product input unit of this utility model adopts a conveying roller, which has a simple and reliable structure and can stably and continuously convey products, avoiding product deviation or accumulation during the input process, ensuring the smooth progress of subsequent sealing and cutting processes, and is easy to maintain and clean.

[0017] (3) The sealing and slitting unit of this utility model combines a slitting roller with circumferentially distributed sealing and slitting heads. Each sealing and slitting head is controlled by an independent drive component, realizing high-precision sealing and slitting actions, adapting to different product specifications, improving processing flexibility and product quality. The vacuum chamber and adsorption hole design inside the slitting roller generates adsorption force through vacuum equipment, effectively fixing the product sealing and slitting process, preventing product slippage or deformation, ensuring sealing firmness and cut neatness, and improving product aesthetics and safety.

[0018] (4) The transfer unit of this utility model adopts a combination of an adsorption transfer roller, a first guide roller and a first tension roller, and is driven by a first belt to achieve smooth and efficient transfer of the cut product. The adsorption transfer roller provides reliable adsorption force to prevent the product from falling or being damaged; the first tension roller ensures constant belt tension and stable transmission; the product output unit and the first belt form a conveying channel, which enables the product to smoothly enter the output stage, reduces the risk of jamming, and improves the overall reliability of the device.

[0019] (5) The product output unit of this utility model forms a stable conveying system through the triangular layout of the traction roller, the second tension roller and the two second guide rollers, combined with the second belt (4-4) drive. The second tension roller ensures uniform belt tension. The conveying channel is formed by the gap between the first belt and the second belt (4-4), so that the product is subjected to uniform force during the output process, is not easy to deform or fold, and ensures the integrity and neat arrangement of the product. It is suitable for high-speed output scenarios.

[0020] (6) The first belt and the second belt (4-4) of this utility model are densely covered with through holes to improve the adsorption of the product. At the same time, the through hole design reduces the weight of the belt, reduces energy consumption, and extends service life. Attached Figure Description
