Description

Technical Field

[0001] The utility model relates to the technical field of light source mechanisms, in particular to a light source mechanism for a camera weft straightening machine and the weft straightening machine. Background Art

[0002] Weft straightening machines are widely used in the post-treatment production process of textile fabrics in the textile industry. The weft straightening machine cooperates with its control system through devices to perform weft straightening on textile fabrics, correct problems such as weft skew and weft arc generated during the processing of textile fabrics, improve the quality and appearance of textile fabrics, and avoid weft skew and weft arc problems. A camera mechanism is installed on the weft straightening machine. The camera mechanism is used to perform real-time photography and monitoring of the texture of textile fabrics, and analyze problems such as weft skew and weft arc of textile fabrics through software. Since the camera mechanism directly aims at the texture of textile fabrics for photography, it is necessary to supplement light for the textile fabrics. Therefore, a light source mechanism is installed on the other side (back side) of the textile fabrics to supplement light for the textile fabrics. The camera mechanism observes the texture on the textile fabrics to further judge the production situation of the textile fabrics. The existing light source mechanism mainly includes a light source and a protective glass. The light of the light source directly penetrates the protective glass and irradiates onto the textile fabrics. Due to the influence of the tungsten wire (filament) in the middle of the existing halogen lamp bulb of the light source and the protrusion in the middle of the bulb, and the influence of the too small light emission angle of the bulb, when the camera mechanism photographs the texture of textile fabrics, it is obvious that there are some black spots and uneven strength in the middle of the textile fabrics, and the light transmittance of the overall light-emitting surface is uneven, resulting in too many error rates, low accuracy and large errors in the texture of the textile fabrics photographed by the camera mechanism, reducing the accuracy of photography, affecting the production quality of textile fabrics, and seriously leading to the phenomenon of scrapping of textile fabrics, increasing production costs. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is: to solve the problems that due to the influence of the tungsten wire in the middle of the existing halogen lamp bulb of the light source and the protrusion in the middle of the bulb, and the influence of the too small light emission angle of the bulb, when the camera mechanism photographs the texture of textile fabrics, it is obvious that there are some black spots and uneven strength in the middle of the textile fabrics, and the light transmittance of the overall light-emitting surface is uneven, resulting in too many error rates, low accuracy and large errors in the texture of the textile fabrics photographed by the camera mechanism, reducing the accuracy of photography, affecting the production quality of textile fabrics, and seriously leading to the phenomenon of scrapping of textile fabrics, increasing production costs. Now, a light source mechanism for a camera weft straightening machine and the weft straightening machine are provided.

[0004] The technical solution adopted by the present utility model to solve its technical problems is as follows: A light source mechanism for a camera weft straightening machine, including a light source box, further including a light source and a light-transmitting component. Both the light source and the light-transmitting component are arranged on the light source box. The light-transmitting component includes a first optical glass and a second optical glass. One side surface of the first optical glass and the second optical glass is subjected to frosted treatment. Both the first optical glass and the second optical glass are made of K9 material glass. The first optical glass and the second optical glass are opposite and spaced apart. The second optical glass is located between the first optical glass and the light source, and the light source is arranged opposite to the second optical glass. Compared with the prior art, in this solution, the surface of the optical glass is subjected to frosted treatment. The side with single-sided frosting is installed facing the light source side. The light is diffusely reflected by the optical glass and then radiates out in all directions. The light passes through the two spaced first optical glass and second optical glass, realizing a more uniform divergence of the light, preventing the phenomenon of uneven intensity, the occurrence of darkening areas, and the generation of obvious light spots, and achieving a more uniform transmission within a certain range, thereby achieving a uniform light effect, ensuring that the texture of the textile fabric captured by the camera is clearer, the uniformity of the light on the image is better, improving the accuracy of the captured image, and ensuring the production quality of the textile fabric.

[0005] In order to better ensure the light transmittance of the light-transmitting component, in some preferred embodiments, the light-transmitting component further includes a sleeve. The first optical glass is fixed at one end of the sleeve, and the second optical glass is fixed at the other end of the sleeve. A sealed cavity is formed between the sleeve, the first optical glass, and the second optical glass. The sleeve is fixedly installed on the light source box. By installing the first optical glass and the second optical glass at intervals on the sleeve, the sleeve restricts the light emitted by the first optical glass, concentrates the light and directs it onto the second optical glass, and the light will be evenly diffused onto the second optical glass. Through the secondary divergence of the second optical glass, the light becomes more uniform, which is more conducive to the observation of the camera mechanism.

[0006] In order to facilitate the installation of the sleeve on the light source box, in some preferred embodiments, a limiting shoulder is provided at one end of the sleeve, and a clamping groove is provided on the outer peripheral surface of the sleeve. An installation hole matching the sleeve is opened on the light source box. One end of the sleeve passes through the installation hole and is arranged inside the light source box. The limiting shoulder abuts against the outer peripheral surface of the light source box, and the clamping groove on the sleeve is located inside the light source box and the sleeve is fixed on the light source box by a snap ring. By the limiting shoulder axially abutting against the outer peripheral surface of the light source box and the snap ring being clamped in the clamping groove inside the light source box, the sleeve is fixed on the light source box.

[0007] Since water vapor will enter the sealed cavity, the water vapor will form fog due to the rising temperature, and the fog will affect the light. To prevent the fog from affecting the light, in some preferred embodiments, ventilation holes are provided on the sleeve, and the ventilation holes communicate with the sealed cavity. By providing ventilation holes on the sleeve that communicate with the sealed cavity, the ventilation holes can timely remove the water vapor or fog, reducing the influence of the fog or water vapor on the light.

[0008] To facilitate the manufacture and installation of the light source box, in some preferred embodiments, the light source box includes an outer housing and a rear cover plate. One end of the outer housing is recessed inward to form a concave cavity, and the rear cover plate covers the concave cavity.

[0009] Since the light source emits light and heat, the heat inside the light source box needs to be dissipated to ensure the working temperature of the internal components of the light source box. In some preferred embodiments, a plurality of heat dissipation holes are provided on the outer housing, and the heat dissipation holes communicate with the concave cavity. The heat dissipation holes can exchange the heat in the inner cavity with the external cold air and dissipate the heat inside the light source box.

[0010] In some preferred embodiments, the light source is installed on the rear cover plate, and the light-transmitting component is installed on the outer housing.

[0011] In some preferred embodiments, the heat dissipation holes are located on the side of the outer housing close to the light-transmitting component.

[0012] In some preferred embodiments, assembly holes are provided on the outer peripheral surface of the light source box, and the assembly holes are used for the installation and connection of the light source box to external equipment.

[0013] A weft straightener is installed with a light source mechanism for a camera weft straightener as described above.

[0014] The beneficial effects of the present utility model are as follows: When the light source mechanism for a camera weft straightening machine and the weft straightening machine of the present utility model are in use, by relatively arranging a first optical glass and a second optical glass on one side of the light source, with the frosted surface facing the light source side, the surface of the optical glass is frosted to produce a diffusion and diffuse reflection effect on the transmitted light. The light is diffusely reflected by the optical glass and then transmitted to the light-emitting surface of the light-transmitting component. The light passes through the two spaced-apart first optical glass and second optical glass, realizing more uniform scattering of the light onto the entire light-emitting surface, preventing the occurrence of uneven intensity, darkening areas, and obvious light spots, and achieving more uniform transmission within a certain range, thereby achieving a uniform light effect, ensuring that the camera captures the texture image of the textile fabric more clearly, with better uniformity of the image quality, greatly improving the accuracy of the camera in capturing the texture of the textile fabric and the precision of the captured texture, ensuring the production quality of the textile fabric, avoiding the influence of the tungsten wire in the middle of the bulb and the protrusion in the exact middle of the bulb on the existing light source, and when the imaging mechanism captures the texture of the textile fabric, it is obvious that there are some black spots and uneven intensity phenomena in the middle of the textile fabric, and the light transmittance of the overall light-emitting surface is uneven, affecting the production quality of the textile fabric, and in severe cases, resulting in the scrapping of the textile fabric, increasing the production cost.
