Description

Technical Field

[0001] This utility model belongs to the technical field of printing and dyeing equipment, and more specifically, it relates to a fabric feeding adjustment device for printing and dyeing. Background Technology

[0002] Currently, in the dyeing and printing industry, the fabric feeding process has a crucial impact on the dyeing and printing quality. Traditional fabric feeding devices often have many problems. For example, uneven feeding speed can easily lead to uneven dyeing of the fabric during the dyeing and printing process; some fabric feeding devices cannot effectively adjust according to the thickness, material, and other characteristics of different fabrics, which may cause wrinkles or excessive stretching of the fabric during the feeding process, thereby affecting the dyeing and printing effect and the quality of the fabric.

[0003] Existing equipment cannot effectively protect and buffer the fabric feed. Due to the different speeds of different fabrics, the collisions with the equipment's conveying area also vary. Long-term conveying can cause deformation of the equipment's conveying area, seriously affecting the fabric feeding and spreading operations. It cannot automatically adjust and buffer, cannot guarantee the stability of the fabric conveying process, and is prone to wrinkles and deviations. It also cannot detect and analyze the internal fabric conveying process, thus having certain limitations. Utility Model Content

[0020] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a fabric feeding adjustment device for printing and dyeing, comprising a wire mesh box body, one end of which is connected to a symmetrical fabric spreading chamber, the diameter of which gradually decreases along the tail of the wire mesh box body, one end of which is connected to a buffer chamber, one end of which is connected to a deflecting bend, the bottom of which is provided with a fabric feeding pipe for fabric feeding, the buffer chamber being equipped with a detection mechanism to detect the pressure released upon impact after the fabric enters the buffer chamber, the top of which is equipped with an electrical control box to control the real-time detection of the detection mechanism, the detection mechanism including a buffer baffle installed in the buffer chamber. At the corner, a pressure detector is installed on the buffer baffle. This detector detects the pressure of the fabric entering the buffer chamber. If the pressure is too high, it indicates that the fabric conveying speed is too fast, requiring buffering and speed reduction adjustment. The pressure detector is electrically connected to an electrical control box for signal transmission. An adjusting pressure plate is installed inside the buffer chamber at the location where it connects to the fabric spreading chamber. This adjusting pressure plate is installed within an adjusting frame and has an elliptical cross-section, providing good buffering and guiding properties, a large contact surface, and good buffering effect. A drive assembly is connected to the top of the adjusting frame, and this drive assembly is electrically connected to the electrical control box, allowing the received pressure signal to be transmitted to the drive assembly, which then drives the adjusting frame. The frame is adjustable in height to facilitate stable fabric transport and provide continuous and stable buffer guidance. The drive assembly includes a drive box with a guide seat at its bottom, which connects to the buffer chamber. A side mounting plate is located inside the drive box, and a motor is mounted on the side mounting plate. The motor's drive end engages with a transmission belt via a pulley. An adjustment seat is located below the side mounting plate, and a pulley is mounted on the adjustment seat via a rotating shaft, which engages with the transmission belt. An adjustment gear is mounted on the other end of the rotating shaft. A slide is located on one side of the adjustment gear, and a toothed surface on one side of the slide engages with the adjustment gear. The slide slides on a guide rail mounted on the side of the drive box. The slide block has a buffer spring connected to its top, and a positioning plate connected to the top of the buffer spring. The positioning plate is fixed to the top of the drive box. A slide rod is provided at the bottom of the slide block, and the slide rod slides within the guide seat. An adjustment frame is connected to the bottom of the slide rod. The slide block is raised and lowered by a motor, which in turn adjusts the mounting frame at the bottom of the slide rod, allowing the adjustment plate to automatically adjust and buffer the fabric, thus guiding and buffering the fabric for subsequent fabric spreading operations. A row of guide strips is provided on both the upper and lower inner walls of the spreading chamber. The guide strips are installed at an angle, and the angle of the guide strips is the spreading direction, which facilitates fabric conveying and prevents the fabric from continuously touching the inner wall of the spreading chamber, causing deformation of the spreading chamber or wear on the fabric.

[0023] The specific usage and function of this embodiment are as follows: First, the fabric enters the turning bend from the inlet pipe for turning and conveying. The fabric passes through the buffer chamber and the spreading chamber in sequence, and finally enters the main body of the mesh box. It is independently conveyed and spread through dual channels. When the fabric passes through the buffer chamber, it will collide with the inner wall. After the fabric collides with the buffer baffle, the pressure detector will transmit the pressure to the electrical control box. The electrical control box controls the motor drive in the drive box to adjust the height according to the pressure. The motor drives the adjusting gear on the adjusting seat to rotate, so that the sliding seat meshing with it can be raised and lowered. This drives the adjusting pressure plate on the adjusting frame to apply pressure to the fabric for buffering, improving the conveying stability of the fabric. The elliptical guide surface can provide better guidance and buffering, and also protect the fabric to a certain extent. The inclined guide strip in the spreading chamber can protect the fabric and prevent it from continuing to collide with the inside during spreading, causing wrinkles and displacement, which would affect subsequent operations.

[0024] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate. The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it.
