Description

Technical Field

[0001] This utility model relates to the technical field of face towel production lines, specifically to a face towel production line with integrated printing function. Background Technology

[0002] Existing facial towel production lines typically include basic processes such as unrolling, slitting, folding, and packaging, which can meet the production needs of traditional facial towels. However, with the upgrading of market consumption and the growth of personalized demands, consumers have placed higher demands on the appearance design, pattern diversity, and product quality of facial towels. Therefore, printing technology has been introduced into facial towel production to enhance the product's aesthetics and market competitiveness.

[0003] In traditional production processes, printing is typically treated as a separate post-processing step, distinct from the main production line. This method has the following drawbacks:

[0004] Low production efficiency: Printing needs to be completed in separate equipment or processes, which increases the complexity of the production process by separating it from the overall production line, resulting in a decrease in overall efficiency and difficulty in meeting the needs of large-scale orders.

[0005] High risk of material deformation: Multiple unwinding and rewinding operations are required before and after printing, which can easily cause the substrate to stretch or wrinkle, affecting the accuracy and consistency of the printed pattern, and even leading to an increase in the product defect rate.

[0006] Therefore, a face towel production line with integrated printing function is needed to overcome the above problems. Utility Model Content

[0007] To address the aforementioned problems, this utility model provides a face towel production line with integrated printing function, thereby achieving the goal of solving the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model embodiment adopts the following technical solution: a face towel production line with integrated printing function, comprising: a raw material unwinding device, serving as the starting end of the production line, carrying the substrate roll and continuously releasing the substrate; a printing device, located downstream of the raw material unwinding device, printing on the substrate conveyed by the raw material unwinding device; a precision cutting device, located downstream of the printing device, performing width shaping and cutting on the printed substrate; a face towel folding device, located downstream of the precision cutting device, folding the width-shaped and cut substrate; a face towel slitting device, located downstream of the face towel folding device, slitting the long strip substrate formed after folding; and a packaging device, serving as the end of the production line, packaging the slitting substrate.

[0009] As a further improvement to the above technical solution:

[0010] The raw material unwinding device is configured as unwinding device one and unwinding device two, so as to release two portions of substrate at the same time.

[0011] The printing apparatus includes: a coating unit, located downstream of the raw material unwinding device, for coating two substrates with ink; and a drying unit, located downstream of the coating unit, for drying the two substrates after ink coating.

[0012] The coating unit includes: a frame, a printing cylinder detachably mounted on the frame with a preset pattern engraved on its surface, which transfers ink to the substrate by pressure, an ink trough mounted on the frame and located below the printing cylinder, which stores water-based environmentally friendly ink, and a doctor blade mounted on the frame and located on the side of the printing cylinder, which is used to scrape off excess ink from the surface of the printing cylinder to control the ink layer thickness.

[0013] The beneficial effects of this utility model embodiment are as follows:

[0014] This production line integrates the printing unit into the main production line, enabling simultaneous printing and production. This not only significantly improves production efficiency but also effectively reduces the risk of material deformation by minimizing intermediate winding cycles. The innovative design of the double unwinding structure and double coating unit meets the needs of large-scale production while also enabling differentiated printing for different products, significantly enhancing the flexibility of the production line.

[0020] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0021] See Figure 1This utility model discloses a face towel production line with integrated printing function, including a raw material unwinding device 1, a printing device 2, a precision cutting device 3, a face towel folding device 4, a face towel slitting device 5, and a packaging device 6 arranged sequentially according to the production process. The raw material unwinding device 1 serves as the starting end of the production line, used to carry the substrate roll and continuously release the substrate. The raw material unwinding device 1 has a double unwinding structure, including unwinding device one 11 and unwinding device two 12, which can release two substrates simultaneously for parallel processing, improving production efficiency.

[0022] The printing device 2 is located downstream of the raw material unwinding device 1 and includes a coating unit 21 and a drying unit 22. The coating unit 21 adopts a modular design and includes a frame 214, a printing plate cylinder 211, an ink trough 212, and a doctor blade 213.

[0023] The printing cylinder 211 is detachably mounted on the frame 214. Its surface is engraved with a preset pattern. Ink is transferred to the substrate by pressure. The printing pattern can be quickly switched by changing the printing cylinder with a different pattern. The ink trough 212 is installed below the printing cylinder 211 to store environmentally friendly water-based ink, while the doctor blade 213 is used to precisely control the ink layer thickness on the surface of the printing cylinder.

[0024] In particular, this embodiment sets up two independent coating units 21, which can perform differentiated printing treatment on two substrates respectively. By configuring printing rollers 211 with different patterns and inks in the two coating units, the innovative effect of presenting different printed patterns between finished single pieces is achieved.

[0025] The drying unit 22 is located downstream of the coating unit 21. It uses four sets of hot air penetration drying equipment to efficiently dry the printed substrate, ensuring that the ink cures quickly without damaging the substrate.

[0026] The precision cutting device 3 is located downstream of the printing device 2 and is used to cut the printed substrate to achieve width shaping. This device solves the problem of inconsistent width of the substrate caused by stretching and drying after printing. By precisely adjusting the device, it ensures that the two rolls of substrate maintain a uniform width, thereby reducing material waste at the source.

[0027] The precision cutting device 3, installed before the folding device, ensures accurate alignment of the two rolls of substrate in subsequent processes. The face towel folding device 4 employs a multi-stage folding mechanism to precisely fold the shaped substrate. The face towel slitting device 5 uses a high-speed rotating blade assembly to slit the folded strips of substrate into individual face towel products. Finally, the packaging device 6 completes the automated packaging of the products, forming a complete production closed loop.

[0028] This production line integrates the printing unit 2 into the main production line, enabling simultaneous printing and production. This not only significantly improves production efficiency but also effectively reduces the risk of material deformation by minimizing intermediate winding cycles. The innovative design of the double unwinding structure and double coating unit meets the needs of large-scale production while also enabling differentiated printing for products, significantly enhancing the flexibility of the production line.

[0029] As an optional embodiment of this application:

[0030] In practice, a stainless steel air shaft is used to simultaneously load two rolls of twin pure cotton spunlace fabric with a diameter of 800mm, a width of 1490mm, and a weight of 50g onto the raw material unwinding equipment. When the substrate passes through the printing device 2 during continuous unwinding, the printing cylinder with a preset printing pattern engraved on its surface accurately transfers environmentally friendly water-based ink to the surface of the spunlace fabric under pressure to form the printing pattern. The two sets of printing cylinders 211 can be configured with different engraved patterns and inks to achieve differentiated printing effects. The effective printing width is set to 1600mm. The doctor blade 213 is configured at a 25° angle and maintains a working pressure of 0.25MPa to ensure that the ink layer thickness is uniform and controllable. After printing, the spunlace fabric enters the drying unit 22, which consists of four sets of hot air penetration drying equipment, and undergoes efficient drying and curing treatment at a constant temperature of 130°C. Then, the printed spunlace fabric is shaped and edge-aligned by a precision cutting device 3 with single-sided or double-sided cutting modes to ensure the accuracy of subsequent processing. The shaped and aligned substrate is then folded in multiple stages by a washcloth folding device 4 and slit by a washcloth cutting device 5. Finally, the finished product is packaged by an automated packaging machine to form a washcloth product with differentiated printing effects.
