Description

Technical Field

[0001] The utility model relates to the technical field of fabric flattening, in particular to a flattening structure of a dobby loom. Background Art

[0002] The large jacquard pattern is woven by a jacquard loom. The number of warp yarns in a complete dobby pattern can be as many as thousands. Most dobby patterns are based on one weave and show pattern designs with another weave, such as plain weave patterns and satin weave patterns. Sometimes, different colored warp and weft yarns can also be used to make the fabric show large colorful patterns. Different fiber types, yarn counts, and different warp and weft densities can also be used to make dobby fabrics of various styles. The application of dobby weave is also very extensive, commonly used in textiles such as bedding, curtains, and blankets. When a dobby loom is working, a fabric flattening device is needed to flatten the fabric for processing the fabric, and a flattening device is required.

[0003] Publication No.: CN218621259 discloses a fabric flattening device for a dobby loom. The output shaft of the first motor rotates to drive the rotating cylinder to rotate and drive the fabric on the surface. At the same time, the second motor is started, and the output shaft rotates to drive the driving gear to engage with the transmission gear to drive the lead screw to rotate, so that the lead screw drives two movable blocks to move relatively on the outer wall of the lead screw, driving the limiting blocks, and the bottom ends of the limiting blocks limit the upper surface of the fabric. In this way, not only can the fabric be flattened, but also the fabric can be limited, avoiding the fabric arching and causing wrinkles in the fabric during the processing of the loom. It can limit fabrics of different widths, thus effectively improving the applicability of the flattening device.

[0004] However, the above device does not limit the fabric roll during use, so that the roll will move during the flattening process, and wrinkles are likely to occur at the edges of the fabric. Therefore, a flattening structure for a dobby loom needs to be proposed. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the defect that the fabric roll is prone to move in the prior art, resulting in wrinkles at the edges of the fabric, and to propose a flattening structure of a dobby loom.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A flattening structure of a jacquard machine, comprising a bottom box of the device. A limiting mechanism is arranged on one side of the bottom box of the device. A mounting plate is fixedly installed at the top of the bottom box of the device. Pressing mechanisms are symmetrically arranged at both ends of the mounting plate. A pressing roller is arranged at the top of the mounting plate. Tension mechanisms are symmetrically arranged at both ends of the bottom box of the device. A tension roller is arranged at the top of the bottom box of the device. The limiting mechanism includes a pair of symmetrically arranged clamping plates. An installation groove is formed on the adjacent side of the pair of clamping plates. A sliding groove is formed on the side of the bottom box of the device close to the clamping plate. A pair of mounting columns are slidably arranged in the sliding groove. A threaded groove is formed at one end of the mounting column close to the clamping plate. A threaded column is fixedly installed on one side of the clamping plate close to the mounting column. The threaded column is threadedly installed in the threaded groove. An adjusting component for adjusting the distance between the clamping plates is arranged in the bottom box of the device. A strengthening component is arranged above the mounting column.

[0008] Preferably, the adjusting component includes a threaded rod rotatably installed in the bottom box of the device. A plurality of limiting rods are fixedly installed in the bottom box of the device. Reverse threads are arranged at both ends of the threaded rod. A pair of lead screw blocks are symmetrically and threadedly sleeved at both ends of the threaded rod. The lead screw blocks are slidably sleeved on the limiting rods. A forward and reverse motor is fixedly installed on the outer side wall of the bottom box of the device. The output shaft of the forward and reverse motor is fixedly connected to the threaded rod coaxially. The outer side wall of the lead screw block is fixedly connected to the mounting column.

[0009] For restricting the fabric roll, thread the threaded rod into the threaded groove so that both clamping plates are fixedly connected to the mounting column. At the same time, the pair of clamping plates are arranged oppositely. Start the forward and reverse motor. The forward and reverse motor drives the threaded rod to rotate. As the threaded rod rotates, the pair of lead screw blocks approach or move away from each other. The lead screw blocks drive the clamping plates to move through the mounting columns. After the clamping plates move to the appropriate positions, install the fabric roll in the installation groove to realize the restriction of the fabric roll.

[0010] Preferably, the strengthening component includes a fixed T-shaped rail fixedly installed at the top of the mounting column. A T-shaped sliding groove is formed on the side of the mounting plate close to the clamping plate. A strengthening inclined rod is arranged between the fixed T-shaped rail and the T-shaped sliding groove. T-shaped sliders are fixedly installed at both ends of the strengthening inclined rod. The T-shaped sliders are respectively slidably arranged in the fixed T-shaped rail and the T-shaped sliding groove.

[0011] For increasing the strength of the clamping plate and the mounting column. After the fabric roll is installed, by sliding the T-shaped slider into the fixed T-shaped rail and the T-shaped sliding groove, a certain connection is established between the clamping plate, the mounting column and the mounting plate, offsetting a part of the acting force of the fabric roll.

[0012] Preferably, the pressing mechanism includes a pressing box fixedly installed on the outer side wall of the mounting plate. A pressing plate is slidably arranged in the pressing box. A plurality of pressing rods are fixedly installed at the top of the pressing plate. A plurality of pressing springs are arranged in the pressing box. The pressing springs are elastically connected between the bottom end of the inner bottom of the pressing box and the bottom end of the pressing plate.

[0013] The compression rod slides through the top end of the compression box, and a first rotating mounting seat is fixedly installed at the top end of the compression rod. The compression roller is rotatably installed between the first rotating mounting seats;

[0014] It is used to offset the pressure generated by the fabric on the compression roller. When the compression roller is subjected to the pressure generated by the fabric, the compression roller moves the pressure plate downward through the first rotating mounting seat and the compression rod, thereby compressing the compression spring. Under the reaction force of the compression spring, the compression roller is supported to a certain extent, and the pressure generated by the fabric on the compression roller is offset to ensure the tension degree of the fabric.

[0015] Preferably, the tension mechanism includes a tension box fixedly installed on the outer side wall of the equipment bottom box. A tension plate is slidably arranged in the tension box. A plurality of tension rods are fixedly installed at the top end of the tension plate. A tension spring is sleeved on the tension rod, and the tension spring is elastically connected between the top end of the tension box and the top end of the tension plate;

[0016] The tension rod slides through the top end of the tension box, and a second rotating mounting seat is fixedly installed at the top end of the tension rod. The tension roller is rotatably installed between the second rotating mounting seats;

[0017] It is used to offset the tension generated by the fabric on the tension roller. When the tension roller is subjected to the tension generated by the fabric, the tension roller drives the tension plate to move upward through the second rotating mounting seat and the tension rod, thereby compressing the tension spring. The reaction force of the tension spring pushes the tension plate downward, thereby offsetting the pressure generated by the fabric on the tension roller to ensure the tension degree of the fabric.

[0018] The utility model has the following beneficial effects:

[0019] 1. By setting the limiting mechanism, the threaded rod is threadedly installed in the threaded groove, so that a pair of clamping plates are fixedly connected to the mounting column. At the same time, the pair of clamping plates are arranged oppositely. Start the forward and reverse motor, and the forward and reverse motor drives the threaded rod to rotate. As the threaded rod rotates, a pair of lead screw blocks approach or move away from each other. The lead screw block drives the clamping plate to move through the mounting column. After the clamping plate moves to a suitable position, the fabric roller is installed in the placement groove to realize the limitation of the fabric roller.

[0020] 2. By setting the compression mechanism and the tension mechanism, the compression roller is supported to a certain extent under the reaction force of the compression spring, and the pressure generated by the fabric on the compression roller is offset. The reaction force of the tension spring pushes the tension plate downward, thereby offsetting the pressure generated by the fabric on the tension roller to ensure the tension degree of the fabric.
