Description

Technical Field

[0001] This utility model relates to the technical field of fabric inspection technology, specifically to a fabric hole detection device. Background Technology

[0002] Fabric is a commonly used material in decoration. Depending on the material, it can be divided into various types such as chemical fiber fabric, non-woven fabric, linen, nylon fabric, colored adhesive fabric, and flannel. Before using the fabric, it is necessary to check for any damage to avoid adverse situations that may result from holes in the fabric.

[0003] In the existing technology, when inspecting fabric, the fabric is usually placed on the feed shaft and take-up shaft of the worktable. The drive device drives the feed shaft and take-up shaft to rotate. After passing through the feed shaft, the fabric enters the laser detection position and is then sent out from the take-up shaft, thereby completing the inspection of the fabric.

[0004] During detection, the signal emitted by the laser emitter can be received by the laser receiver. When the fabric passing through has no holes, the laser receiver cannot receive the signal due to the obstruction of the fabric, indicating that there are no holes in the fabric. However, when the fabric has holes, the obstruction disappears, and the laser receiver can receive the signal, indicating that there are holes in the fabric. Therefore, the presence of holes in fabric can be detected by whether the signal emitted by the laser emitter can be received by the laser receiver.

[0005] However, since it's impossible to guarantee the correct fabric delivery position after passing the feed shaft and entering the laser detection position, misalignment of the fabric at this position will affect the detection process, impacting its stability and efficiency. It will also negatively affect the subsequent winding process. Furthermore, due to the continuous nature of the detection process, stopping the machine for inspection after discovering holes in the fabric will also reduce detection efficiency.

[0006] Therefore, there is an urgent need to provide a new solution to address the defects and shortcomings of the existing technologies. Utility Model Content

Its features are: Limiting devices are provided on both sides of the U-shaped plate, and an auxiliary device is provided on the top of the U-shaped plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] [First Embodiment] like Figure 1-4 The image shows a fabric hole detection device provided in the first embodiment of this utility model. Figure 1 As shown, the system includes a workbench 1, a U-shaped plate 2 fixed to the top of the workbench 1, a laser emitter 3 fixed inside the U-shaped plate 2, and a laser receiver 4 positioned on the top of the workbench 1 corresponding to the laser emitter 3 to receive signals emitted by the laser emitter 3. During detection, the signals emitted by the laser emitter 3 can be received by the laser receiver 4. When the fabric passing through has no holes, the laser receiver 4 cannot receive the signals emitted by the laser emitter 3 due to the obstruction of the fabric, indicating that there are no holes in the fabric. However, when the fabric passing through has holes, the obstruction disappears, and the laser receiver 4 can receive the signals emitted by the laser emitter 3, indicating that there are holes in the fabric. Therefore, the presence of holes in the fabric can be detected by whether the signals emitted by the laser emitter 3 can be received by the laser receiver 4.

[0027] To facilitate the conveying of the fabric, a feeding shaft 5 is rotatably installed at the inlet end of the workbench 1, and a receiving shaft 6 is rotatably installed at the outlet end of the workbench 1. The fabric is placed on the feeding shaft 5 and the receiving shaft 6 of the workbench 1, and a drive device (not shown, but a common drive device such as a motor can be selected) drives the feeding shaft 5 and the receiving shaft 6 to rotate. After passing through the feeding shaft 5, the fabric enters the laser detection position (i.e., the position where the laser emitter 3 and the laser receiver 4 are located) and is then sent out from the receiving shaft 6, thereby completing the detection of the fabric. The improvement of this embodiment compared to the prior art is that: limiting devices 7 are provided on both sides of the U-shaped plate 2, and an auxiliary device 8 is provided on the top of the U-shaped plate 2; by setting the limiting devices 7, the fabric passing through the detection position is limited to avoid misalignment, thereby ensuring the stability of the detection process and improving detection efficiency; at the same time, the limiting devices 7 can be adaptively adjusted according to the width of the fabric, thereby increasing the applicable range and applicability of the limiting devices; in addition, by setting the auxiliary device 8, after a hole is detected in the fabric, the corresponding position can be marked with a marking liquid for subsequent inspection and correction, thereby avoiding the adverse effects on detection efficiency caused by stopping the machine for inspection after a hole is detected in the fabric, and ensuring detection efficiency.

[0028] like Figure 2-3 As shown, the limiting device 7 in this embodiment includes a sliding rod 71 that slides through both sides of the U-shaped plate 2. A baffle 72 is fixed to the end of the sliding rod 71 that extends into the inner side of the U-shaped plate 2. The baffle 72 achieves the stopping and limiting effect on both sides of the fabric. The sliding rod 71 is slidably connected to the U-shaped plate, so the position of the baffle 72 inside the U-shaped plate can be adjusted according to the width of the fabric, thereby improving the applicability of the limiting device 7.

[0029] To limit the sliding trajectory of the slide rod 71, a limiting rod 78 is fixed to the outside of the baffle 72. A rectangular plate 77 is fixed at the top of the worktable 1 at the position corresponding to the limiting rod 78. The limiting rod 78 slides through the rectangular plate 77. When the slide rod 71 drives the baffle 72 to slide relative to the U-shaped plate 2, the limiting rod 78 will also slide inside the rectangular plate 77 through the baffle 72, thereby achieving the effect of limiting the sliding trajectory of the slide rod 71 during the sliding process and avoiding unexpected deviation.

[0030] Once the slide bar 71 has slid to the desired position, a fixing plate 73 is fixed to both sides of the U-shaped plate 2 and above the slide bar 71 to position the slide bar 71. A positioning element 74 is installed inside the fixing plate 73. Several positioning parts 75 are provided at the top of the slide bar 71. These positioning parts 75 engage with the positioning elements 74 to achieve the positioning effect of the slide bar 71 at the current position. Figure 2-3 As shown, in this embodiment, the positioning member 74 is a bolt threadedly connected to the fixing plate 73, while the positioning part 75 is a protruding rubber sheet. The positioning member 74 is adjusted relative to the fixing plate 73 through its thread to achieve contact with the positioning part 75, thereby achieving the positioning effect. To achieve the positioning effect of the slide rod 71 at the current position, those skilled in the art will know that the positioning member 74 and the positioning part 75 can also be configured with other structures (for example, the positioning member 74 can be configured as a positioning protrusion, and the positioning part can be configured as a positioning hole or positioning groove, etc.).

[0031] Preferably, to prevent the positioning component 74 from being accidentally dropped or lost, the positioning component 74 is fixedly connected to one end of the pull rope 76, and the other end of the pull rope 76 is fixedly connected to the fixing plate 73.

[0032] like Figure 2 and Figure 4 As shown, the top of the U-shaped plate 2 in this embodiment is provided with an auxiliary device 8. The auxiliary device 8 includes a placement frame 81 fixed to the top of the U-shaped plate 2. The interior of the placement frame 81 is filled with marking liquid. Several nozzles 82 that pass downward through the U-shaped plate 2 are fixed to the bottom of the placement frame 81. The interior of the placement frame 81 can communicate with the nozzles 82. The marking liquid is sprayed onto the fabric at the detected hole position through the nozzles 82 to achieve the marking effect of the hole position.

[0033] To enable on-demand spraying of the marking liquid, a switch 83 connected to the laser receiver 4 is provided on one side of the nozzle 82. When a hole is detected in the fabric, the laser receiver 4 sends a control signal to open the switch 83, allowing the marking liquid inside the placement frame 81 to be sprayed from the nozzle 82 onto the detected hole location on the fabric. When no hole is detected, the laser receiver 4 sends a control signal to close the switch 83, preventing the marking liquid inside the placement frame 81 from being sprayed from the nozzle 82. The switch 83 can be a commonly used switch such as a solenoid valve. To minimize the adverse effects of the marking liquid on the fabric, the marking liquid is preferably an easy-to-clean liquid type so that it can be easily washed away after the hole location is determined.

[0034] To monitor the level of the marking liquid inside the placement frame 81 in real time, a scale is provided on one side of the placement frame 81, and a transparent glass 84 is embedded on one side of the placement frame 81 corresponding to the position of the scale for easy observation.

[0035] The specific working process of this embodiment is as follows: Before inspecting the fabric, move the slide bar 71. The slide bar 71 brings the two baffles 72 closer to each other until the two baffles 72 are on both sides of the fabric. The operator controls the positioning part 74 on the fixed plate 73 to cooperate with the positioning part 75 below to position the slide bar 71 at its current position, thereby achieving the limiting effect on both sides of the fabric through the slide bar 71.

[0036] When inspecting the fabric, the fabric enters the laser inspection position via the feed shaft 5 and emits a signal through the laser emitter 3 inside the U-shaped plate 2. When there are no holes in the fabric, the laser receiver 4 cannot receive the signal emitted by the laser emitter 3 due to the obstruction of the fabric, indicating that there are no holes in the fabric. However, when there are holes in the fabric, the obstruction disappears, and the laser receiver 4 can receive the signal emitted by the laser emitter 3, indicating that there are holes in the fabric. After inspection, the fabric is sent out from the take-up shaft 6 through the laser inspection position.

[0037] Meanwhile, when a hole is detected in the fabric, the laser receiver 4 sends a control signal to open the switch 83, and the marking liquid inside the placement frame 81 is sprayed out from the nozzle 82 and sprayed onto the detected hole location on the fabric; when no hole is detected in the fabric, the laser receiver 4 sends a control signal to close the switch 83, and the marking liquid inside the placement frame 81 cannot be sprayed out from the nozzle 82, so as to facilitate marking the holes in the fabric. The auxiliary device 8 achieves the effect of marking the holes in the fabric, making it convenient for staff to observe and correct the position of the holes in the fabric.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
