Description

Technical Field

[0001] The utility model relates to the field of detection equipment, in particular to a fabric sampling tool. Background Art

[0002] When a testing company is commissioned by a client to take fabric samples, it is necessary to take out a piece of fabric that meets the required size from the center of the fabric to be tested for subsequent testing, such as water absorption, shrinkage, weight, etc.

[0003] Since the inspection volume was not large before, the company generally used a cardboard as a template, pressed it on the surface of the fabric, drew a circle with an oil-based pen, and then slowly cut along the fabric with scissors. This operation method requires the operator to have great patience.

[0004] The following prior art can be found about fabric sampling equipment:

[0005] Publication number: CN117969146A A hand-pressed curled fabric testing and sampling device;

[0006] Publication number: CN104155139A A quantitative sampler for fabrics;

[0007] The above solution has a relatively complex structure and focuses more on aspects such as automatic cutting.

[0008] However, in our production applications, cutting is indeed very time-consuming and labor-intensive, but spending too much money to purchase an automated cutting equipment is not in line with economic purposes.

[0009] Therefore, the technical problem solved in this case is: how to improve the convenience of fabric sampling while taking into account the simplicity of the equipment. Utility Model Content

[0010] The main purpose of the utility model is to provide a fabric sampling tool. The tool does not focus on cutting, but only focuses on how to fix the fabric. After the fabric is fixed, the fabric can be quickly cut by rotating the first fixed disk and the second fixed disk and using a utility knife. The edges of the cut fabric are clear and complete. At the same time, the mold used in the tool is cardboard, which is low in price and can be changed in shape and size according to the detection requirements.

[0011] The technical solution provided by the utility model is as follows: a fabric sampling tool, comprising a base, a lower support column, an upper pressure column, a driving module for driving the upper pressure column to rise and fall, a first cardboard, and a second cardboard; the top of the lower support column is provided with a horizontally arranged first fixed disk; the bottom of the upper pressure column is connected to a horizontally arranged second fixed disk; the first fixed disk and the second fixed disk are freely rotatable; the first cardboard is bonded to the upper surface of the first fixed disk; the center of the second cardboard is provided with an opening;

[0012] The areas of the first paperboard and the second paperboard are both larger than the first fixed plate and the second fixed plate; when the upper pressure column drives the second fixed plate to press downward, the second paperboard is placed between the first paperboard and the second fixed plate.

[0013] This solution abandons the traditional automatic cutting design and only uses a first and second fixed plate that can be flexibly rotated. The upper pressure column tightly presses the fabric between the first and second cardboards. Once fixed, the fabric can be cut along the edge of the cardboard with a utility knife while the first and second fixed plates rotate synchronously, making it easy to cut the desired shape.

[0014] It achieves the dual goals of equipment simplicity and cutting accuracy, and can meet the company's cost expenditure requirements.

[0015] The beneficial effects of the utility model are as follows:

[0016] This solution uses a freely rotatable first fixed plate, a second fixed plate combined with a first cardboard fixed to the first fixed plate, and a second cardboard that is not fixedly connected to the first and second fixed plates. This can well fix the cloth to facilitate cutting. At the same time, by opening a hole in the center of the second cardboard, the operator can see the marking point of the center of the cloth to prevent the cloth from being shifted.

[0021] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods, but this does not constitute any limitation to the present invention.

[0022] refer to Figure 1A fabric sampling tool comprises a base 1, a lower support column 2, an upper pressure column 3, a driving module 4 for driving the upper pressure column 3 to rise and fall, a first cardboard 5, and a second cardboard 6; a first fixed plate 7 arranged horizontally is provided on the top of the lower support column 2; a second fixed plate 8 arranged horizontally is connected to the bottom of the upper pressure column 3; the first fixed plate 7 and the second fixed plate 8 are freely rotatable; the first cardboard 5 is bonded to the upper surface of the first fixed plate 7; an opening 9 is provided in the center of the second cardboard 6;

[0023] The areas of the first paperboard 5 and the second paperboard 6 are both larger than the first fixed plate 7 and the second fixed plate 8; when the upper pressure column 3 drives the second fixed plate 8 to press downward, the second paperboard 6 is placed between the first paperboard 5 and the second fixed plate 8.

[0024] During the production process, follow the steps below:

[0025] Step 1: Fold the square fabric in half, find the center point, and mark the center point with a marker;

[0026] Step 2: Reference Figure 2 , place the cloth on the first cardboard 5, cover the cloth with the second cardboard 6, move the cloth so that the mark can be seen through the opening 9, and ensure that the edges of the first cardboard 5 and the second cardboard 6 are aligned;

[0027] Step 3: Reference Figure 3 , the upper pressing column 3 moves downward, pressing the second cardboard 6 through the second fixed plate 8;

[0028] Step 4: Use a utility knife to cut the fabric until it touches the edges of the first cardboard 5 and the second cardboard 6. Pull the corners of the fabric. The first fixed plate 7 and the second fixed plate 8 will slowly rotate as the utility knife cuts until the outer edge of the entire fabric is cut off. Then check whether there are any scraps left over. If there are any, trim them with scissors.

[0029] Step 5: The upper pressure column 3 moves upward, and the cloth is taken out to see if it is a standard circle. If not, the sample is discarded. If it is, subsequent testing is carried out.

[0030] Preferably, reference Figure 3 and Figure 4 , and also includes a plurality of U-shaped clips 10; when the cloth is clamped by the first cardboard 5 and the second cardboard 6, the lower surface of the first cardboard 5 and the upper surface of the second cardboard 6 are clamped in the U-shaped clips 10; the plurality of U-shaped clips 10 are arranged at multiple positions on the periphery of the first cardboard 5 and the second cardboard 6 to align the edges of the first cardboard 5 and the second cardboard 6.

[0031] The U-shaped clips 10 are used in step 2. Before step 3, ensure that the edges of the first cardboard 5 and the second cardboard 6 are aligned. Use at least three U-shaped clips 10 to clamp the first cardboard 5 and the second cardboard 6, respectively, and then proceed to step 3. The use of U-shaped clips 10 can improve the fixing accuracy and cutting accuracy of the fabric.

[0032] In this embodiment, a frame 11 is further included. The base 1 is fixed on the frame 11 , and the driving module 4 and the upper pressure column 3 are fixed on the frame 11 .

[0033] In this embodiment, there are two ways to realize the rotation of the first fixed plate 7 and the second fixed plate 8:

[0035] 2. The lower support column 2 is rotatably connected to the base 1 through a bearing; the second fixed plate 8 is movably connected to the upper pressure column 3 through a bearing.

[0036] In this embodiment, the first implementation method is preferably adopted.

[0037] Preferably, the first and second fixing plates 7 and 8 are both trumpet-shaped; the thick ends of the first and second fixing plates 7 and 8 are each provided with an outwardly extending annular body 12; the first cardboard 5 is fixed to the annular body 12 of the first fixing plate 7 by adhesive; and the driving module 4 is a driving module 4 using a pneumatic cylinder or an oil cylinder as a power source, or a screw driving module 4.
