Description

Technical Field

[0001] This utility model relates to the field of garment processing technology, specifically to a fabric inspection machine used in garment processing. Background Technology

[0002] The fabric inspection machine provides the hardware environment for fabric inspection, continuously unfolds the fabric in sections, provides sufficient light, and allows operators to visually observe and detect surface defects and color differences. At the same time, it automatically completes the length recording and roll-up sorting work. The intelligent fabric inspection machine uses multiple high-pixel cameras to automatically inspect fabric defects and color differences. It can detect various defects such as holes, stains, and broken yarns, and can also score the fabric and generate a professional fabric inspection report.

[0003] For example, patent CN218989695U discloses a light source fabric inspection machine, including a light source fabric inspection machine body. First mounting frames are installed on both sides of the front surface of the light source fabric inspection machine body. The first mounting frames have combing grooves. Mounting blocks are installed at both ends of the inner side of the first mounting frames. The mounting blocks have slots inside, and locking blocks are engaged inside the slots. The locking blocks are fixedly installed at the bottom end of a cleaning brush. An adjustment knob is provided at the bottom end of the light source fabric inspection machine body, and the adjustment knob is electrically connected to the light source fabric inspection machine body. The cleaning brush allows the fabric to pass through... After passing through the combing groove, the fabric enters the main body of the light source fabric inspection machine. During the transmission process, the cleaning brush will clean the upper and lower surfaces of the fabric, thereby removing impurities attached to the upper and lower surfaces of the fabric. Some elastic fabrics, such as knitted fabrics and spandex fabrics, are prone to local stretching or shrinkage if the tension is uneven during transmission due to the strong elasticity of the fibers. This can lead to wrinkles or overall skewing. Fabric wrinkles can cover part of the fabric surface, making it impossible for operators or the camera of the intelligent fabric inspection machine to observe defects such as holes, broken yarns, and stains under the wrinkles, resulting in missed inspections and affecting the fabric inspection results.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing fabric inspection machine. Summary of the Invention

[0005] The purpose of this invention is to provide a fabric inspection machine for garment processing, in order to solve the problem mentioned in the background art that some elastic fabrics, such as knitted fabrics and spandex fabrics, are prone to local stretching or shrinkage due to the strong fiber elasticity. This can lead to wrinkles or overall skewing if the tension is uneven during transmission. The wrinkles can cover part of the fabric surface, making it impossible for operators or the camera of the intelligent fabric inspection machine to observe defects such as holes, broken yarns, and stains under the wrinkles, resulting in missed inspections and affecting the fabric inspection results.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fabric inspection machine for garment processing, comprising a machine frame and a detection area set on the machine frame for inspecting fabric quality. A feeding shaft for discharging fabric is rotatably mounted on the machine frame, and a guide roller shaft for guiding the fabric is located below the feeding shaft on the machine frame. A positioning roller shaft for positioning and driving the fabric is fixed on the machine frame. An upper pressure roller and a lower pressure roller are located above and below the detection area on the machine frame, with the lower pressure roller positioned above the positioning roller shaft. A stretching assembly for stabilizing, limiting, and stretching the fabric is provided on the machine frame.

[0007] Preferably, the stretching assembly includes a support frame fixedly installed on the equipment platform, a rotating frame rotatably installed on the support frame, an adjusting frame movably arranged on the side of the rotating frame, and a pressure bar that presses against the fabric installed on the adjusting frame.

[0008] Preferably, a guide column is fixedly installed on the support frame, and an adjusting column is telescopically slidably connected in the guide column. The adjusting column is fixedly connected to the adjusting frame. A disc is fixedly sleeved on the outside of the adjusting column. A main return spring is elastically connected between the disc and the guide column, and a secondary return spring is elastically connected between the adjusting frame and the rotating frame. The main return spring and the secondary return spring are sleeved on the outside of the adjusting column.

[0009] Preferably, an electric telescopic rod is fixedly installed on the support frame, a positioning block is fixedly connected to the output end of the electric telescopic rod, and a transmission rod is rotatably connected to the positioning block.

[0010] Preferably, a transmission arm is fixed on the rotating frame in a direction perpendicular to the rotation axis, and the transmission arm is rotatably connected to the transmission rod.

[0011] Preferably, the equipment frame is provided with a limiting mechanism that limits the material release position on the feeding shaft.

[0012] Preferably, the limiting mechanism includes a vertical frame fixedly installed on the equipment platform. The vertical frame has two sets of symmetrically arranged about the feeding axis. A stop wheel that presses against the fabric surface is movably arranged between the two sets of feeding axes. A lifting block is longitudinally slidably connected in the vertical frame. The lifting block is fixedly connected to the stop wheel, and the upper and lower surfaces of the lifting block are elastically connected to the inside of the vertical frame through positioning springs.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the fabric inspection machine for garment processing can stretch both ends of the fabric located in the inspection area, limit the distribution position of the fabric in the inspection area, and keep the fabric in a fully stretched state to avoid the situation of missed detection due to wrinkles in the fabric.

[0014] The equipment platform is equipped with a stretching component that stabilizes and limits the fabric. When the fabric is transferred to the detection area, the positioning block is driven by an electric telescopic rod. Under the transmission of the transmission rod and transmission arm, the rotating frame and adjusting frame are controlled to rotate and approach the fabric. The pressure rod presses against the fabric surface, limiting the fabric detection position and pushing the fabric to move and unfold to both sides, keeping the fabric in a fully unfolded state, thus improving the fabric inspection effect.

[0015] Furthermore, the equipment frame is equipped with a limiting mechanism that limits the position of the fabric being released from the feeding shaft. As the feeding shaft rotates and releases the fabric, the stop wheel, under the action of gravity and the elastic tension of the positioning spring, moves down and presses against the fabric roll edge on the surface of the feeding shaft, thus limiting the fabric transmission and preventing the feeding shaft from rotating and releasing excess fabric under the inertial tension of the fabric transmission, thereby maintaining a moderate tension in the fabric transmission.

Detailed Implementation

[0024] 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.

[0025] Example 1: Please refer to Figures 1-4 The present invention provides the following technical solution: a fabric inspection machine for garment processing, comprising a machine frame 1 and a detection area 2 set on the machine frame 1 for inspecting fabric quality, a feeding shaft 3 for rotating and feeding fabric is rotatably mounted on the machine frame 1, a guide roller shaft 4 for guiding fabric is set below the feeding shaft 3 on the machine frame 1, a limiting roller shaft 5 for positioning and driving fabric is fixed on the machine frame 1, and an upper pressure roller 7 and a lower pressure roller 6 are set above and below the detection area 2 on the machine frame 1, with the lower pressure roller 6 located above the limiting roller shaft 5; a stretching component 8 for stabilizing, limiting and stretching fabric is set on the machine frame 1.

[0026] Please see Figure 4 and Figure 5 The stretching assembly 8 includes a support frame 81 fixedly installed on the equipment platform 1, a rotating frame 82 rotatably installed on the support frame 81, an adjusting frame 83 movably arranged on the side of the rotating frame 82, and a pressure bar 84 pressed onto the fabric installed on the adjusting frame 83.

[0027] Please see Figures 4-7 A guide column 85 is fixedly installed on the support frame 81. An adjusting column 86 is slidably connected to the guide column 85 and is fixedly connected to the adjusting frame 83. A disc 87 is fixedly sleeved on the outside of the adjusting column 86. A main return spring 88 is elastically connected between the disc 87 and the guide column 85. A secondary return spring 89 is elastically connected between the adjusting frame 83 and the rotating frame 82. The main return spring 88 and the secondary return spring 89 are sleeved on the outside of the adjusting column 86. An electric telescopic rod 811 is fixedly installed on the support frame 81. A positioning block 812 is fixedly connected to the output end of the electric telescopic rod 811. A transmission rod 813 is rotatably connected to the positioning block 812. A transmission arm 814 is fixedly fixed on the rotating frame 82 along the vertical direction of the rotation axis. The transmission arm 814 is rotatably connected to the transmission rod 813.

[0028] The fabric roll is placed outside the feeding shaft 3. The fabric is stretched outward along the direction of the guide roller shaft 4 and the limiting roller shaft 5. The lower pressure roller 6 presses and restricts the fabric stretched on the limiting roller shaft 5. The stretched fabric moves through the detection area 2 to the upper end of the equipment platform 1. Under the further restriction of the upper pressure roller 7, the fabric is kept in the state of being distributed in the detection area 2. During detection, the fabric is controlled to move to the detection area 2. Under the illumination of the light source, the operator or a high-definition camera detects whether there are defects on the surface of the fabric. After detection, the fabric is controlled to move. The fabric at different positions is continuously controlled to move to the detection area 2, thus realizing the quality inspection of the fabric.

[0029] When the fabric is moved to the surface of the detection area 2, the electric telescopic rod 811 pushes the positioning block 812 to move. The two ends of the transmission rod 813 connected between the positioning block 812 and the transmission arm 814 rotate accordingly. The rotating transmission rod 813 can push the transmission arm 814 to rotate. The transmission arm 814 is fixed on the rotating frame 82, which controls the rotating frame 82 mounted on the support frame 81 to rotate closer to the fabric, so that the pressure rod 84 presses against the fabric surface. The rotating frame 82 continues to rotate. With the cooperation of the main return spring 88 and the auxiliary return spring 89, the adjusting column 86 on the adjusting frame 83 moves through the rotating frame 82, which drives the pressure rod 84 to press against the fabric surface and move laterally. This causes the pressure rods 84 on both sides to stretch the fabric to both ends, keeping the fabric in a fully unfolded state, avoiding the situation where the fabric surface wrinkles cause missed detection, and improving the quality of fabric inspection.

[0030] Example 2: Please refer to Figures 1-3 Based on Embodiment 1, a limiting mechanism is also disclosed, the specific structure of which is as follows: A limiting mechanism is provided on the equipment frame 1 to limit the material release position on the feeding shaft 3. The limiting mechanism includes a vertical frame 9 fixedly installed on the equipment frame 1. Two sets of vertical frames 9 are symmetrically arranged about the feeding shaft 3. A stop wheel 10 pressed against the surface of the material is movably arranged between the two sets of feeding shafts 3. A lifting block 11 is longitudinally slidably connected in the vertical frame 9. The lifting block 11 is fixedly connected to the stop wheel 10, and the upper and lower surfaces of the lifting block 11 are elastically connected to the inside of the vertical frame 9 through positioning springs 12.

[0031] Under tension, the fabric is intermittently stretched and moved to the surface of the detection area 2. During the stretching and movement, it can drive the feeding shaft 3 to rotate. A stop wheel 10 is pressed on the fabric roll outside the feeding shaft 3. During the process of the fabric rotating and being released, the stop wheel 10 can adjust itself in accordance with the diameter of the fabric roll. Under the action of gravity and the elastic tension of the positioning spring 12, it can control the lifting block 11 to be fitted into the stand 9 and gradually move downward. The lifting block 11 drives the stop wheel 10 to move downward synchronously, so that the stop wheel 10 is appropriately pressed and limited on the surface of the fabric roll, preventing the fabric roll from rotating and releasing excess fabric under the action of inertial tension, and maintaining the detection state of the fabric with appropriate tension.
