Description

Technical Field

[0001] This utility model relates to the field of printing machinery and equipment, and to an online roller changing printing press for printing patterns on the surface of non-woven fabrics. Background Technology

[0002] Currently, non-woven fabric surface pattern printing machines on the market mainly use upper and lower hot rollers to press and shape the fabric. If the pattern to be changed during production, the upper or lower hot roller must be replaced, which requires downtime and consumes a lot of time and labor. Therefore, it is not suitable to frequently change the pattern of the product, otherwise the equipment utilization rate will be significantly reduced, leading to a decrease in production efficiency.

[0003] The surface of the patterned roller is covered with dotted raised patterns, which increases the heat dissipation area. This causes the dotted raised patterns to dissipate heat quickly, resulting in a relatively low temperature at the tip of the dotted raised patterns, which affects the hot rolling and shaping of the smooth roller and the patterned roller.

[0004] When producing products with a relatively small weight, if the fabric is too thin and there are few fibers at both ends, it is easy to form scattered fibers, resulting in poor peelability and easy roll wrapping. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an online roller-changing printing press for printing patterns on the surface of nonwoven fabrics.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an online roller-changing printing press for printing patterns on the surface of non-woven fabrics, comprising a left roller-changing assembly, a right roller-changing assembly, a support frame, and a support roller. The support frame has a support rod supported by a lifting assembly between the discharge port and the inlet. The support rod has baffles on both sides and the lower end, forming an upward-opening inner cavity. The left roller-changing assembly is located on the discharge port side of the inner wall of the support frame. A left hot roller that moves above the discharge port and the support rod is located on the left roller-changing assembly. The right roller-changing assembly is located on the inlet port side of the inner wall of the support frame. A right hot roller that moves above the inlet port and the support rod is located on the right roller-changing assembly. Heat transfer oil is circulated inside the support roller, the left hot roller, and the right hot roller. The left hot roller and the right hot roller are patterned rollers with dotted patterned protrusions on their outer surfaces, and the support roller is a smooth roller with a smooth outer surface.

[0007] Furthermore, baffles are provided at the lower ends of both sides of the support roller, and the baffles gradually move closer together to form an inner cavity with a smaller lower end and a larger upper end, with the opening facing upwards. The support roller is located at the opening of the inner cavity.

[0008] Furthermore, the left roller changing assembly includes a left elevator, a left swing arm, and a left hot roller. A left elevator is installed on each of the two side walls at the lower end of the support frame's discharge port. The upper ends of the two left elevators are rotatably connected to the lower ends of the corresponding left swing arms. One side of each left swing arm is also rotatably connected to the inner wall of the support frame on the corresponding side. The inner sides of the upper ends of the two left swing arms are rotatably connected to the corresponding sides of the left hot roller, driving the left hot roller to move at the position where it contacts the support rod at the upper end of the support frame. The right roller changing assembly includes a right elevator, a right swing arm, and a right hot roller. A right elevator is installed on each of the two side walls at the lower end of the support frame's inlet. The upper ends of the two right elevators are rotatably connected to the lower ends of the corresponding right swing arms. One side of each right swing arm is also rotatably connected to the inner wall of the support frame on the corresponding side. The inner sides of the upper ends of the two right swing arms are rotatably connected to the corresponding sides of the right hot roller, driving the right hot roller to move at the position where it contacts the support rod at the upper end of the support frame.

[0009] Furthermore, the left and right roller changing assemblies are symmetrically arranged on both sides of the support roller.

[0010] Furthermore, a discharge roller is provided inside the discharge port.

[0011] Furthermore, the discharge roller is equipped with air blowing pipes on both sides along the width of the equipment.

[0012] Furthermore, the air blowing device blows air towards the separation point between the fabric surface and the discharge roller.

[0013] Furthermore, the upper end of the inner cavity, corresponding to the right side of the pattern roller that works in contact with the support roller, is provided with a heating part for heating the dotted pattern protrusions, which is arranged along the width direction of the equipment.

[0014] The beneficial effects of this utility model are: simple structure, support for online replacement of pattern rollers as needed, adapt to the required pattern, significantly shorten roller change time, improve production efficiency, and reduce downtime;

[0015] By heating the surrounding airflow during the operation of the light roller, the hot airflow carries the pattern roller upward, creating an environment with a higher temperature than the ambient temperature. This raises the temperature of the raised tips of the dot pattern, allowing the raised tips of the dot pattern to print better on the fabric during the pressing process.

[0016] By using an air-blowing device to assist in back-blowing, loose fibers at both ends of the fabric are promptly blown away from the pattern roller, helping the fibers to follow the fabric and peel off from the pattern roller in real time and enter the next stage, greatly reducing the risk of the fibers getting tangled on the roller.
