Description

Technical Field

[0001] The utility model relates to the technical field of knitted fabrics, in particular to a density increasing device for cashmere knitted fabrics. Background Art

[0002] A knitted fabric is formed by yarns through regular knitting movements to form loops, and the loops are strung together to form a fabric. Therefore, the loop is the smallest basic unit of the knitted fabric. This is also an important sign for identifying knitted fabrics. The raw materials that can be used for knitting knitted fabrics are relatively wide, including cotton, wool, silk, linen, chemical fibers, and their blended yarns or cross-wound yarns, etc. When detecting knitted fabrics, a knitted fabric density meter is required.

[0003] The density measurement of traditional cashmere knitted fabrics is carried out by manual density increasing. The specific method is to clamp the four corners of the knitted fabric, stretch the reverse side of the cashmere knitted fabric longitudinally and measure the number of wales of the loops under a certain tensile condition, so as to correct and measure the density of the cashmere knitted fabric. However, the existing clamps generally use bolts to press the knitted fabric. After pressing, when detecting the knitted fabric, the bolts may retreat, resulting in the knitted fabric suddenly retracting during the pulling process, so that the knitted fabric needs to be detected again, which brings inconvenience to the use of the knitted fabric density increasing device. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that when detecting the knitted fabric, the bolts may retreat, resulting in the knitted fabric suddenly retracting during the pulling process, so that the knitted fabric needs to be detected again.

[0010] As a further solution of the present utility model, a sliding groove enabling the moving member to slide therein is arranged on the moving frame.

[0011] The advantages of the present utility model compared with the prior art are as follows:

[0012] 1. By arranging the first motor to drive the gear to rotate, the gear meshes with the gear rack to drive the clamping members to move relatively. When stretching the knitted fabric, since the first motor locks the gear and the gear cannot rotate, and through the meshing mode of the gear rack and the gear, the teeth on the gear rack are stuck with the gear, thereby making the clamping members unable to retract, improving the detection stability of the device;

[0013] 2. By arranging bolts threadedly connected to the C-shaped clamping members, rotating the handle drives the bolt to rotate, thereby driving the pressing plate to move downward. After firmly pressing the knitted fabric, rotate the locking nut for reinforcement, further improving the stability of the device. Description of the Drawings
