Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a cylindrical fabric splitting device. Background Art

[0002] An electronic jacquard circular knitting machine is a circular knitting machine that uses a computer to control patterns. Yarns are fed in from the weft direction to form fabric, so it is also called a weft knitting machine; the fabric woven by this machine is cylindrical, so a splitting process is required during the post-treatment process to unfold the cylindrical fabric into a flat shape. In order to reduce the creases that appear after the fabric is unfolded, when the grey fabric is wound up, it is generally flattened and wound up based on the draw thread of the grey fabric, so that one end of the grey fabric roll is the draw thread and the other end is the crease line after being flattened.

[0003] The existing splitting of cylindrical grey fabric is processed through a fabric spreading device. After the fabric is spread, the operator aligns the draw thread of the grey fabric with the splitting knife and splits the grey fabric along the draw thread to become a flat width process. During the processing, the operator needs to visually observe the position of the draw thread of the grey fabric and the splitting knife. However, due to the inconsistent positions and heights of the fabric opening personnel, the difference in angles forms a visual misjudgment, which easily causes the splitting to be skewed, thereby affecting the quality of the fabric opening and causing waste of the grey fabric. Content of the Utility Model

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art. A cylindrical fabric splitting device is provided, which solves the above problems by means of the existing method of flattening and winding based on the draw thread.

[0005] To achieve the above purpose, a cylindrical fabric splitting device is provided, including a top bracket and an original embryo roller frame. The top bracket is vertically arranged with the original embryo roller frame. In the middle below one end of the top bracket, a hanging rod is fixedly connected. The end of the hanging rod far from the top bracket is vertically and fixedly connected with a horizontal support rod. The end of the horizontal support rod far from the hanging rod is fixedly connected with a connecting rod. Near one end of the hanging rod below the horizontal support rod, a U-shaped frame is fixedly connected. On both sides below the top bracket near one end of the hanging rod, a fabric spreading inclined rod is fixedly connected. Above the top bracket near one end of the hanging rod, a winding roller is rotatably connected. At a position corresponding to the winding roller on one side above the top bracket, a winding motor is fixedly connected.

A connecting plate is fixedly connected to the outer side of the fixing sleeve. A cutting protective sleeve is fixedly connected to the lower side of the connecting plate. A driving motor is fixedly connected to one side of the cutting protective sleeve close to the winding motor. A cloth-cutting circular knife is fixedly sleeved on the output shaft of the driving motor. Rubber pressing wheels are fixedly sleeved on both sides of the output shaft of the driving motor on the cloth-cutting circular knife. A cutting groove is formed at the position of the U-shaped frame corresponding to the cloth-cutting circular knife. Triangular plates are fixedly connected to both sides of the U-shaped frame at the cutting groove.

[0007] According to the described cylindrical fabric splitting device, one end of the connecting rod far from the horizontal cross bar is fixedly connected to the inner top of one end of the U-shaped frame far from the suspension rod.

[0008] According to the described cylindrical fabric splitting device, both ends of the two cloth-supporting inclined rods far from the top bracket are fixedly connected to one end of the connecting rod close to the U-shaped frame.

[0009] According to the described cylindrical fabric splitting device, the output end of the winding motor is in transmission connection with the rotating shaft of the winding roller.

[0010] According to the described cylindrical fabric splitting device, the triangular plates are all right-angled triangles, and the right-angled sides correspond to the edges of the cutting groove.

[0011] According to the described cylindrical fabric splitting device, the length of the winding roller is twice that of the original embryo roller frame, and the original embryo roller frame is arranged parallel to the bottom of the U-shaped frame.

[0012] The above scheme has at least the following beneficial effects:

[0013] 1. The utility model is provided with a U-shaped frame parallel to the original embryo roller frame. After aligning one end of the drawstring of the cloth roll with one end of the U-shaped frame responsible for cutting, when the two ends of the cloth are propped up along the two ends of the U-shaped frame, under the action of the crease, the subsequent cloth will also continue to feed along the drawstring, avoiding cloth offset, enabling the cloth to automatically perform the splitting process along the drawstring, solving the problems caused by manual alignment, and enhancing the practicability of the device.
