Abstract
Description
Technical Field
[0001] The utility model relates to a decorative cloth detection device, more specifically, it relates to a decorative cloth needle detector. Background Art
[0002] The decorative fabric needle detector is a device specially used to detect whether there are metal needles or other metal impurities in decorative fabrics. Its main working principle is based on magnetic induction technology, which uses built-in magnetic heads and induction coils to sense the magnetic field changes caused by metal impurities in decorative fabrics.
[0003] The working principle of the decorative fabric needle detector is mainly based on magnetic induction technology. When the decorative fabric passes through the detection area of the needle detector, the magnetic field inside the machine will interact with the metal needles or other metal impurities in the decorative fabric. These metal impurities will change the distribution of the magnetic field, which will cause the current of the induction coil inside the needle detector to change. By detecting this current change, the needle detector can accurately determine whether there are metal impurities in the decorative fabric.
[0004] The existing decorative cloth needle detector uses a conveyor belt to transport the decorative cloth and cannot detect from the bottom of the decorative cloth. Since it can only detect from the top of the decorative cloth, it is easy to form a detection blind spot. Especially when the decorative cloth is thick or has a multi-layer structure, metal needles or other metal impurities are easily hidden in the bottom or interlayer of the decorative cloth, and the needle detector above cannot detect them, resulting in a decrease in the overall detection accuracy.
[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
[0006] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a decorative fabric needle detector, which discharges the fabric through a discharge roller. At this time, the fabric is located between two detection sensors. The two detection sensors can form a detection area. When the decorative fabric passes through, the detection sensor will detect the metal impurities therein. The two detection sensors are respectively located above and below the fabric, forming a dual detection mechanism. This means that when the fabric passes through the detection sensor, it will be detected from both the upper and lower sides, increasing the detection coverage and accuracy. The two detection sensors can cover a wider area, ensuring that every part of the fabric can be effectively detected, eliminating blind spots, and improving the comprehensiveness of the detection. The positions of the two detection sensors are adjusted by adjusting the adjustment plate. Different decorative fabrics have different thicknesses, densities and materials. By adjusting the position of the detection sensor by the adjustment plate, it can be ensured that the detection sensor and the fabric are kept at an appropriate distance. In this way, no matter how the thickness or material of the fabric changes, the detection sensor can work in the best state, thereby improving the accuracy of the detection.
[0007] The above technical purpose of the utility model is achieved through the following technical solutions: a decorative fabric needle detector, comprising a processing table, a feeding roller is movably connected to the left side of the upper end of the processing table, a receiving roller is movably connected to the right side of the upper end of the processing table, the feeding roller and the receiving roller are movably connected to the fabric together, a body is fixedly installed on the middle side of the upper end of the processing table, a slide groove is provided at the front end of the body, a driving assembly is arranged inside the slide groove, an adjustment plate is threadedly connected to the upper and lower sides of the outer surface of the driving assembly, a detection sensor is fixedly installed on the opposite sides of the two adjustment plates, and a transmission line is fixedly installed on the opposite back sides of the two detection sensors.
[0008] The utility model is further configured as follows: the driving assembly comprises a servo motor, a positive and negative threaded rod is fixedly mounted on the output end of the servo motor, and the adjustment plate is threadedly connected to the positive and negative threaded rod.

[0010] The utility model is further configured as follows: the cloth is located between two detection sensors.
[0011] The utility model is further configured as follows: a control panel is fixedly installed on the upper side of the front end of the machine body.
[0012] In summary, the utility model has the following beneficial effects:
[0013] 1. The fabric is unloaded through the unloading roller. At this time, the fabric is located between the two detection sensors. The two detection sensors can form a detection area. When the decorative fabric passes through, the detection sensor will detect the metal impurities in it. The two detection sensors are located above and below the fabric, forming a dual detection mechanism. This means that when the fabric passes through the detection sensor, it will be detected from both the top and bottom, increasing the detection coverage and accuracy. The two detection sensors can cover a wider area, ensuring that every part of the fabric can be effectively detected, eliminating blind spots, and improving the comprehensiveness of the detection. The positions of the two detection sensors are adjusted by the adjustment plate. Different decorative fabrics have different thicknesses, densities and materials. By adjusting the position of the detection sensor through the adjustment plate, it can be ensured that the detection sensor and the fabric are kept at an appropriate distance. In this way, no matter how the thickness or material of the fabric changes, the detection sensor can work in the best state, thereby improving the accuracy of the detection.

The two detection sensors 9 can cover a wider area, ensuring that each part of the cloth 4 can be effectively detected, eliminating blind spots, and improving the comprehensiveness of the detection. The positions of the two detection sensors 9 are adjusted by the adjustment plate 8. Different decorative cloths 4 have different thicknesses, densities and materials.

[0022] Four supporting legs 11 are fixedly mounted on the lower end of the processing table 1 , and the supporting legs 11 provide support and stability for the processing table 1 .
[0023] A control panel 12 is fixedly mounted on the upper front side of the body 5, and the control panel 12 makes the operation of the needle detector more intuitive and convenient.
