Description

Technical Field

[0001] The invention relates to the technical field of light transmittance, and in particular to a light transmittance detection device for a woven bag. Background Art

[0002] In the related art, woven bags are woven with embryonic silk as warp and weft. If the gap between the embryonic silk is too large, when the woven bag is loaded with fine particles or powder products, the woven bag may leak. Therefore, when the woven bag leaves the factory, the light transmittance of the woven bag is tested to ensure that the woven bag is a qualified product.

[0003] After searching, the Chinese patent publication number CN220709032U discloses a woven bag transmittance detection device, which belongs to the field of woven bag detection technology; the woven bag transmittance detection device includes: a bottom plate, a first support plate, a lead screw, a first clamping assembly, a second clamping assembly, an LED lamp tube, a test box, an industrial camera, and a cover plate; by rotating the lead screw, the lead screw drives the first clamping assembly and the second clamping assembly to move in relative or opposite directions, thereby adjusting the distance between the first clamping assembly and the second clamping assembly to adapt to woven bags of different specifications, and can also adjust the stretching width of the woven bag, thereby improving the applicability of the product.

[0004] However, when the above patent is in use, it can only detect the light transmittance of one woven bag at a time. When the light transmittance of multiple woven bags needs to be detected, the woven bags need to be disassembled and reassembled before and after the detection, which is cumbersome and reduces the detection efficiency of the light transmittance of the woven bags. At the same time, when the industrial camera needs to be moved to shoot and detect the woven bags, it needs to be manually moved, which is inconvenient to use. Summary of the invention

[0005] The purpose of the present invention is to solve the problems in the background technology and to propose a woven bag light transmittance detection device.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Reference Figures 1 to 5 , a woven bag light transmittance detection device, comprising:

[0035] The detection box 1 has a touch control display 21 and a control switch 22 fixedly mounted on its surface, and the control switch 22 is electrically connected to the touch control display 21 and the motor 7 described below.

[0036] Two feeding ports 2 are respectively provided on the two side walls of the detection box 1 .

[0037] A plurality of conveying rollers 3 are rotatably installed in the detection box 1 in a linear array.

[0038] A driving assembly is used to drive multiple conveying rollers 3 to rotate. The driving assembly includes multiple transmission sprockets 4 coaxially connected to each conveying roller 3, and a first chain 5 is commonly connected between the multiple transmission sprockets 4. A driving roller 6 is rotatably installed in the detection box 1. A rubber airbag 23 is fixedly sleeved on the outer wall of the driving roller 6 to increase the friction force on the surface of the driving roller 6, so that the driving roller 6 can drive the woven bag to move more stably. At the same time, the elasticity of the rubber airbag 23 can also be used to adapt to woven bags of different thicknesses.

[0039] A motor 7 for driving a driving roller 6 is fixedly installed on the outer side of the detection box 1. The end of the driving roller 6 and the end of the corresponding conveying roller 3 are coaxially connected with a gear 8, and the two gears 8 are meshed with each other. When in use, the motor 7 is started to control the rotation of the driving roller 6, and then the corresponding conveying roller 3 starts to rotate under the transmission of the two meshing gears 8, and then under the transmission of multiple transmission sprockets 4 and the first chain 5, the multiple conveying rollers 3 rotate synchronously, so that the woven bags for the required transmittance detection can be automatically transported to the detection box 1, and sent out from another feeding port 2 after the detection is completed.

[0040] The laser emitter 11 and the photosensitive sensor 12 are respectively placed on the lower side and the upper side of the plurality of conveying rollers 3. When the transmittance is detected, the laser emitter 11 emits light, which passes through the surface of the woven bag and directly shines on the photosensitive sensor 12. Finally, the photosensitive sensor 12 senses the intensity and brightness of the light, and the transmittance information of the woven bag can be transmitted to the touch control display 21 and displayed on its screen after processing, thereby realizing the detection of the transmittance of the woven bag.

[0041] The reciprocating detection component is linked with the driving component and is used to move the laser emitter 11 and the photosensitive sensor 12 back and forth on the upper and lower sides of the woven bag. The reciprocating detection component includes two reciprocating screws 9 rotatably installed in the detection box 1. The surfaces of the two reciprocating screws 9 are movably connected with screw sliders 10. The reciprocating screw 9 is a form of a three-dimensional cam pair, which is manifested as two thread grooves with the same pitch and opposite rotation directions. The two ends are connected by a transition curve, and the side of the spiral groove pushes the screw slider 10 placed in the spiral groove to perform axial reciprocating motion.

[0042] A limit assembly is provided between the screw slider 10 and the detection box 1, and the limit assembly includes two limit rods 24 fixedly connected to the opposite ends of the laser emitter 11 and the photosensitive sensor 12 respectively. The inner top wall and the inner bottom wall of the detection box 1 are provided with limit grooves 25, and the two limit grooves 25 are respectively slidably connected to the two limit rods 24. Through the sliding connection between the limit grooves 25 and the limit rods 24, it can be ensured that the screw slider 10 can move back and forth radially along the reciprocating screw 9 when subjected to the torsion of the reciprocating screw 9.

[0043] The opposite sides of the two lead screw sliders 10 are fixed to the laser emitter 11 and the photosensitive sensor 12 respectively. The outer side of the detection box 1 is rotatably installed with driven sprockets 13 coaxially connected to the two reciprocating lead screws 9 respectively. The end of the driving roller 6 is coaxially connected to the driving sprocket 14. The driving sprocket 14 and the two driven sprockets 13 are jointly sleeved with a second chain 15. When the driving roller 6 rotates, the two reciprocating lead screws 9 can be driven to rotate synchronously in the same direction through the transmission of the driving sprocket 14, the two driven sprockets 13 and the second chain 15, so that the two lead screw sliders 10 respectively drive the laser emitter 11 and the photosensitive sensor 12 to move radially synchronously and reciprocatingly. At the same time, in conjunction with the transportation of the woven bag by each conveying roller 3, a comprehensive transmittance detection of the woven bag can be achieved, thereby improving the detection effect and efficiency.

[0044] A dust removal component is used to remove dust and impurities on the surface of the woven bag. The dust removal component includes a hollow frame 16 fixedly connected to the outside of the detection box 1, and the hollow frame 16 is placed outside a feeding port 2 close to the driving roller 6. A plurality of dust suction holes 17 are opened on the inner surface of the hollow frame 16, and a dust suction pipe 18 is fixedly connected to the top of the hollow frame 16. A dust suction pump 19 is fixedly installed on the top of the detection box 1, and the dust suction end of the dust suction pump 19 is connected to the dust suction pipe 18, and the dust outlet end of the dust suction pump 19 is fixedly connected to a filter 20. When the dust suction pump 19 is started, the dust and impurities on the upper and lower surfaces of the woven bag at the feeding port 2 can be sucked into the filter 20 through the dust suction pipe 18 for filtration, so as to avoid the dust and impurities on the surface of the woven bag affecting its transmittance detection.

[0045] Furthermore, the distance between the two conveying rollers 3 in the middle is greater than the distance between the other two adjacent conveying rollers 3, and there is a support plate 26 in contact between the other two adjacent conveying rollers 3. The support plate 26 is fixedly installed in the detection box 1, which can play a certain supporting role on the end of the woven bag.

[0046] The working principle of the present invention is:

[0047] When in use, the woven bag to be tested is inserted into a feeding port 2 near the driving roller 6, the motor 7 is started to control the driving roller 6 to rotate, and then the corresponding conveying roller 3 starts to rotate under the transmission of the two meshing gears 8, and then under the transmission of the multiple driving sprockets 4 and the first chain 5, the multiple conveying rollers 3 rotate synchronously, and the woven bag for the transmittance test can be automatically transported to the detection box 1;

[0048] When the driving roller 6 rotates, the two reciprocating screws 9 can be driven to rotate synchronously in the same direction through the transmission of the active sprocket 14, the two driven sprockets 13 and the second chain 15, so that the two screw sliders 10 respectively drive the laser emitter 11 and the photosensitive sensor 12 to move radially synchronously and reciprocatingly. At the same time, in conjunction with the conveying of the woven bag by each conveying roller 3, the continuous transmittance detection of the woven bag can be achieved;

[0049] During transmittance detection, the laser emitter 11 emits light, which passes through the surface of the woven bag and directly shines on the photosensor 12. Finally, the photosensor 12 senses the intensity and brightness of the light, and the transmittance information of the woven bag can be transmitted to the touch control display 21 and displayed on its screen after processing, thereby realizing the detection of the transmittance of the woven bag.

[0050] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
