Description

Technical Field

[0001] This utility model relates to a material processing device for trademark tape, specifically a bidirectional slitting device for a trademark tape production line. Background Technology

[0002] Label tape is a textile used to identify product information and is attached to clothing and other products. Its main characteristics are flatness, washability, and ease of attaching printed information. Label tape is produced by coating a base fabric with a coating material to make the fabric stiff and flat, and then slitting it. The base fabric of the label tape is a wide fabric woven on a conventional loom, so it needs to be slit multiple times to obtain the required width and length. In order to improve production efficiency, the base fabric is sized and then efficiently slit on the production line. Therefore, multiple slitting devices are required. The slitting direction of the slitting devices may be different. If different models of slitting devices are used, it is inconvenient to purchase components and maintain and repair them. Therefore, a device that can be set to slit in both directions is needed. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a bidirectional slitting device for trademark tape production lines.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: The slitting device includes a frame, a horizontal workstation plate is set on the frame, and a slitting frame is set on the horizontal workstation plate. The slitting frame is set across the passage path of the production line, forming a working space for slitting operations. A slitting blade is set in the working space, and the base fabric to be slitted passes through it flatly. The slitting blade cuts the base fabric. The slitting blade is set on the slitting frame by a blade holder, and a reversing device is set on the blade holder. The slitting blade is set in the working space in either the warp or weft direction through the reversing device. The slitting device is set on the production line by the frame, the horizontal plate forms a horizontal working reference, the slitting frame is set across and forms the slitting processing area, and the slitting blade can be reversed. This allows the slitting device with the same main structure to achieve slitting in different directions. Slitting is mainly achieved through the reversing device, which allows for the replacement of fewer parts, changes in function, improved equipment maintainability, and increased production efficiency.

[0005] Furthermore, the blade holder is connected to the slitting frame via a displacement device. This displacement device includes a bearing housing, a screw, and a moving collar. The moving collar and screw form a ball screw structure. One end of the screw is the drive end and is connected to a servo drive device. The moving collar moves linearly across the lateral span of the slitting frame. The moving collar extends downwards into the workspace and connects to the slitting blade. The displacement device connected to the blade holder can change the lateral position of the blade holder. In the warp slitting mode, it allows for adjustment of the slitting width; in the weft slitting mode, it allows for complete cutting, improving versatility and maintainability.

[0006] Furthermore, the slitting frame is provided with a guide groove, which is parallel to the linear direction of the displacement device. A guide block is fixedly formed at the bottom of the slitting blade, and the guide block moves linearly within the guide groove. The guide groove can guide the slitting blade at the bottom, preventing the slitting blade from becoming skewed after a large amount of work and maintaining the consistency of slitting. The guide groove can be fixed with a rigid straight bar structure.

[0007] Furthermore, the reversing device includes a warp clamp and a weft clamp. The slitting blade is connected to the tool holder via the warp clamp to form a warp slitting structure, and the slitting blade is connected to the tool holder via the weft clamp to form a weft slitting structure. Both the warp and weft clamps are connected to the tool holder via a fitting structure, and each has a clamping opening at its lower end to hold and fix the slitting blade. Since the clamping openings of the warp and weft clamps are in different directions, the cutting edge directions of the fixed slitting blades are different, thus achieving slitting functions in different directions.

[0008] Furthermore, the fitting structure includes a wedge-shaped groove formed at the bottom of the tool holder and wedge-shaped protrusions formed on the upper parts of the warp and weft clamping bodies. The wedge-shaped protrusions and the wedge-shaped groove are mutually clamped and fixed. The fitting structure uses the clamping force of the materials for fixed connection, resulting in good connection rigidity, good working durability, and meeting the requirements of mass production.

[0009] Furthermore, the slitting frame is equipped with guide rollers on both the infeed and outlet sides, and a guide bevel is provided at the lower part of the guide roller. The guide bevel is inclined upward by the station horizontal plate and guides the material to the conveying surface of the guide roller. The guide roller can guide the material of the label tape into the working space, which helps to maintain the flatness of the fabric, improves the slitting accuracy, and ensures stable quality.

[0010] Compared with the prior art, this utility model has the following advantages and effects: This design is an improvement of the slitting device for the production and processing of trademark tapes. It can be installed on the production line, has the same main structure, and can realize slitting functions in different directions. The structure is easy to maintain and parts can be purchased, which helps to improve production efficiency. Attached Figure Description
