This process is time-consuming and laborious, and it also reduces the working efficiency of the fabric inspection machine. Utility Model Content

[0005] The purpose of this invention is to provide a fabric inspection machine that facilitates heat dissipation and allows for convenient replacement of the lamps inside the light box.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fabric inspection machine that facilitates heat dissipation, comprising a machine body, an unwinding table located at the rear of the machine body for storing fabric rolls to be inspected, a winding table located at the front of the machine body for storing fabric rolls after inspection, a light box located inside the machine body and inclined upwards, and multiple lamp tubes arranged inside the light box. An operation port is provided on the back of the light box. A winding tube with a circular cross-section is arranged inside the machine body and below the light box. A winding shaft is arranged inside the winding tube, and a winding shaft is installed at the end of the winding tube. A bearing seat is provided for rotatably connecting the end of the take-up shaft. Both ends of the take-up shaft are provided with a return coil spring, one end of which is connected to the take-up shaft and the other end of which is connected to the inner wall of the take-up tube. The upper side of the take-up tube is provided with a release port corresponding to the operation port position. A covering curtain cloth is provided inside the take-up tube, one end of which is connected to the take-up shaft and the other end of which passes through the release port and is used to cover the operation port. A connecting rod is provided at the end of the covering curtain cloth away from the take-up shaft. Both sides of the light box and the upper side of the operation port are provided with L-shaped first hooks for the end of the connecting rod to be inserted.

[0007] A further feature of this invention is that a first guide roller is provided on the upper side of the machine body and above the unwinding table, a connecting ear is provided on the side of the machine body for connecting the end of the first guide roller, and a second guide roller is provided on the upper side of the machine body and above the light box.

[0008] A further feature of this invention is that: an axial flow fan for blowing air onto multiple lamp tubes is provided on the bottom wall of the lamp box, and an exhaust port is provided on the upper side of the lamp box, the exhaust port being located between the first guide roller and the second guide roller.

[0009] A further feature of this invention is that multiple axial flow fans are provided and are evenly spaced along the extension direction of the lamp tube.

[0010] A further feature of this invention is that: both sides of the light box, and above the exhaust vent, are provided with L-shaped second hooks for embedding the ends of the connecting rods.

[0011] A further feature of this invention is that the covering fabric is a reflective fabric.

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. When the light tube inside the light box is damaged and needs to be replaced, remove the end of the connecting rod from the two first hooks. Then, under the elastic restoring force of the return spring, the rolled-up curtain can be wrapped and rolled into the take-up tube, exposing the operating port. The operator can then remove and install the light tube inside the light box through the operating port. After the outer wall of the light tube is replaced, pull up the connecting rod and the rolled-up curtain until the end of the connecting rod is embedded in the first hook. At this point, the operating port can be covered by the rolled-up curtain. Finally, this facilitates the convenient replacement of the light tube inside the light box.

[0014] The covered roller blind fabric can avoid the fabric that is rolled up on the unrolling table by extending and retracting the cover from the top and bottom, thus making it convenient to replace the light tube after opening the covered roller blind fabric during the fabric inspection process.

[0015] 2. The machine body uses a first guide roller and a second guide roller for the fabric to pass through. The first guide roller is connected by a connecting ear, which allows the first guide roller to be away from the light box position, making it convenient to operate the covering roller curtain after bypassing the fabric during the fabric inspection process.

[0016] 3. Since the multiple lamps inside the light box need to work for a long time, they will generate a lot of heat. If they are not dissipated in time, it will affect their performance and lifespan. At this time, multiple axial flow fans installed on the bottom wall of the light box can be used to dissipate heat from the multiple lamps by exhausting air upwards. At the same time, since the exhaust port is located between the first guide roller and the second guide roller, and the fabric is transferred between the first guide roller and the second guide roller, the airflow discharged from the exhaust port can remove wrinkles from the surface of the fabric, thus realizing multiple uses of airflow.

[0017] 4. Multiple axial flow fans are installed and evenly distributed along the extension direction of the lamp tube. At this time, multiple axial flow fans can efficiently dissipate heat from the lamp tube.

[0018] 5. When the fabric inspection machine is stopped, no air is coming out of the exhaust vent. At this time, the covering roller curtain is passed over the exhaust vent, and then the end of the connecting rod is inserted into the second hook. At this time, the covering roller curtain can cover the operating port and the exhaust vent at the same time, which can prevent dust from falling into the light box from the operating port and the exhaust vent and then adhering to the surface of the lamp tube.

[0019] 6. Use the roller blind fabric as a reflective material. At this time, the roller blind fabric will have a reflective effect, which will help improve the brightness of the light box. Attached Figure Description
