Description

Technical Field

[0001] This utility model relates to the field of fabric grading machine technology, and in particular to a dustproof device for a fabric inspection machine. Background Technology

[0002] In the textile industry's production process, the fabric inspection machine is one of the important pieces of equipment, and its performance plays a crucial role in the finishing effect of the fabric.

[0003] In the fabric inspection machine, the working principle is to use photoelectric sensors to sense and reflect the fabric. When the fabric passes through the sensor, the sensor emits light, which is reflected back after hitting the fabric. The sensor then converts the reflected light into an electrical signal. The signal converter converts the electrical signal received by the sensor into a digital signal that can be processed by a computer. In this way, the computer can analyze and process the digital signal to obtain the quality index of the fabric. During the fabric inspection, wrinkles and dust on the fabric can affect the accuracy of the inspection data. To solve the above problems, we propose a dustproof device for the fabric inspection machine. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dustproof device for a fabric inspection machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A fabric pressing and dust filtering assembly is provided on the upper side of the inspection table. The fabric pressing and dust filtering assembly includes a rotating shaft, on which a plurality of sleeves are sleeved. A rotating rod is rotatably installed on the side of each sleeve. A pressure plate is rotatably installed at the lower end of the rotating rod. A plurality of guide strips are fixedly installed at equal intervals on the bottom of the pressure plate. A lower support plate is fixedly installed on the bottom of each sleeve. A tension sensor is fixedly installed on the upper side of the lower support plate. A spring is fixedly connected to the upper side of the tension sensor. A limit groove is formed on the inner wall of the sleeve. A limit strip adapted to the limit groove is fixedly installed on the outer wall of the rotating shaft.

[0007] Furthermore, a limiting screw is screwed onto the outer wall of the sleeve, and the inner end of the limiting screw abuts against the outer wall of the rotating shaft.

[0008] By adopting the above technical solution, when the limiting screw is tightened, its inner end can abut against the outer wall of the rotating shaft, thereby restricting its sliding freedom on the rotating shaft.

[0009] Furthermore, the guide strip is arranged parallel to the fabric inspection table, the bottom of the pressure plate has several dust suction holes, the inside of the pressure plate is a hollow structure, a connecting pipe is fixedly installed on the upper side of the pressure plate, a collection box is provided on the side of the second support, an air pump is connected to the side of the collection box, the air pump's suction end is connected to the inside of the collection box and a dust filter is installed on the air pump's suction end, an air suction pipe is connected to the upper side of the collection box, and the air suction pipe is connected to several sets of the connecting pipes.

[0010] Furthermore, a first support and a second support are symmetrically fixedly installed on the upper side of the fabric inspection table. A lower arc groove is fixedly installed on the upper side of the first support, and an upper arc groove is screwed onto the upper side of the lower arc groove. The rotating shaft is rotatably installed inside the lower arc groove and the upper arc groove.

[0011] By adopting the above technical solution, the upper arc groove is screwed to the upper side of the lower arc groove. Then, by disassembling the lower arc groove, the end of the rotating shaft can be opened, making it easy to pull out the sleeve from the end, which facilitates the subsequent inspection and maintenance of parts.

[0012] Furthermore, the rotating shaft rotates through to the outside of the second support, and a large gear is fixedly installed at the end of the rotating shaft. A built-in motor is provided on the side of the large gear, and a small gear is fixedly installed on the output end of the built-in motor. The small gear meshes with the large gear.

[0013] Furthermore, the built-in motor is fixedly installed on the outer wall of the second support, and a cover is fixedly installed on the outer side of the second support.

[0014] By adopting the above technical solution, the shroud provides protection for the gear meshing space.

[0015] Furthermore, the side of the casing is provided with several heat dissipation holes.

[0016] Furthermore, a support leg is fixedly installed at the bottom of the fabric inspection table, and a controller is fixedly installed at the front of the fabric inspection table.

[0017] By adopting the above technical solution, the heat dissipation holes provide a heat dissipation channel for the built-in motor inside the casing.

[0018] Furthermore, a support plate is fixedly installed on the left side of the fabric inspection table, and a fabric rolling roller and a guide roller are rotatably installed on the inner side of the support plate, with fabric rolled onto the outer side of the fabric rolling roller.

[0021] Compared with related technologies, the dustproof device for a fabric inspection machine proposed in this utility model has the following beneficial effects:

[0022] In this utility model, a dustproof device for a fabric inspection machine is provided. Through a fabric pressing and dust filtering assembly, a pressure plate presses against the upper side of the fabric. During the conveying and winding process, the fabric is subjected to pressure from the pressure plate, making it smoother. When the sleeve rotates counterclockwise, it drives the pressure plate to continue pressing down. At this time, the spring is stretched, and its return force gradually increases, used to press thinner fabrics, avoiding incomplete wrinkle removal. Simultaneously, a tension sensor can sense the return force provided by the spring. The controller precisely controls the return force of the spring, thus precisely controlling the pressure provided by the pressure plate on the fabric. This allows for adapting to different thicknesses or types of fabrics, providing appropriate pressure for wrinkle removal, improving the wrinkle removal effect, keeping the fabric inspected at the bottom of the inspection machine smooth, avoiding inspection errors, and enhancing practicality.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Reference Figures 1-6 A dustproof device for a fabric inspection machine includes an inspection table 1, on which a fabric inspection machine 10 is fixedly installed. A fabric pressing and dust filtering assembly 9 is provided on the upper side of the inspection table 1. The fabric pressing and dust filtering assembly 9 includes a rotating shaft 94, on which a plurality of sleeves 912 are sleeved. A rotating rod 915 is rotatably installed on the side of each sleeve 912. A pressure plate 916 is rotatably installed at the lower end of the rotating rod 915. A plurality of guide strips 920 are fixedly installed at equal intervals at the bottom of the pressure plate 916. A lower support plate 917 is fixedly installed at the bottom of each sleeve 912. A tension sensor 918 is fixedly installed on the upper side of the lower support plate 917. A spring 919 is fixedly connected to the upper side of the tension sensor 918. A limit groove is formed on the inner wall of the sleeve 912. 913, A limiting strip 95 adapted to the limiting groove 913 is fixedly installed on the outer wall of the rotating shaft 94. It should be noted that the working principle of the fabric inspection machine 10 is to use a photoelectric sensor to sense and reflect the fabric. When the fabric passes through the sensor, the sensor emits light. After the light shines on the fabric, it is reflected back. The sensor then converts the reflected light into an electrical signal. The function of the signal converter is to convert the electrical signal received by the sensor into a digital signal that can be processed by the computer. In this way, the computer can analyze and process the digital signal to obtain the quality index of the fabric. This is a common fabric inspection device, and will not be elaborated on further here.

[0032] Through the above structure, the setting of the limiting groove 913 and the limiting strip 95 restricts the rotational freedom of the sleeve 912 on the rotating shaft 94.

[0033] In this embodiment, a first support 91 and a second support 96 are symmetrically fixedly installed on the upper side of the fabric inspection table 1. A lower arc groove 92 is fixedly installed on the upper side of the first support 91, and an upper arc groove 93 is screwed onto the upper side of the lower arc groove 92. A rotating shaft 94 is rotatably installed inside the lower arc groove 92 and the upper arc groove 93.

[0034] With the above structure, the upper arc groove 93 can be removed from the lower arc groove 92, which makes it easy to disassemble and repair the sleeve 912 from the side of the rotating shaft 94.

[0035] In this embodiment, the rotating shaft 94 rotates through to the outside of the second support 96 and a large gear 99 is fixedly installed at the end of the rotating shaft 94. A built-in motor 910 is provided on the side of the large gear 99. A small gear 911 is fixedly installed on the output end of the built-in motor 910. The small gear 911 meshes with the large gear 99. The built-in motor 910 is fixedly installed on the outer wall of the second support 96. A cover 97 is fixedly installed on the outside of the second support 96.

[0036] With the above structure, when the built-in motor 910 starts, it can drive the small gear 911 to mesh with the large gear 99 to rotate, thereby driving the rotating shaft 94 to drive the sleeve 912 to rotate, so as to adjust the pressure applied by the pressure plate 916 to the fabric.

[0037] In this embodiment, the machine cover 97 has several heat dissipation holes 98 on its side, the bottom of the inspection table 1 is fixedly installed with support legs 2, and the front of the inspection table 1 is fixedly installed with a controller 3.

[0038] Through the above structure, the heat dissipation hole 98 provides heat dissipation, and the support leg 2 provides support for the fabric inspection table 1.

[0039] In this embodiment, a support plate 4 is fixedly installed on the left side of the fabric inspection table 1. A fabric rolling roller 5 and a guide roller 6 are rotatably installed on the inner side of the support plate 4. Fabric 8 is rolled on the outer side of the fabric rolling roller 5. A drive motor 7 is fixedly installed on the side of the support plate 4. The output end of the drive motor 7 rotates through to the inner side of the support plate 4 and is connected to the shaft coupling of the fabric rolling roller 5.

[0040] With the above structure, after the drive motor 7 starts, it can drive the fabric roll roller 5 to rotate, thereby providing power for the winding of the fabric 8.

[0041] In this embodiment, a limiting screw 914 is screwed onto the outer wall of the sleeve 912, and the inner end of the limiting screw 914 abuts against the outer wall of the rotating shaft 94.

[0042] With the above structure, the limiting screw 914 can restrict the sliding freedom of the sleeve 912 on the rotating shaft 94.

[0043] In this embodiment, the guide strip 920 is arranged parallel to the inspection table 1. The bottom of the pressure plate 916 is provided with several dust suction holes 921. The inside of the pressure plate 916 is a cavity structure. A connecting pipe 925 is fixedly installed on the upper side of the pressure plate 916. A collection box 922 is provided on the side of the second support 96. An air pump 923 is connected to the side of the collection box 922. The air suction end of the air pump 923 is connected to the inside of the collection box 922 and a dust filter is installed on the air suction end of the air pump 923. An air suction pipe 924 is connected to the upper side of the collection box 922. The air suction pipe 924 is connected to several sets of connecting pipes 925.

[0044] With the above structure, the guide strip 920 is set parallel to the inspection table 1, so that the guide strip 920 will not cause excessive friction to the fabric during the fabric conveying process. At the same time as the fabric is conveyed, the air pump 923 is turned on to extract air, thereby creating negative pressure in the air extraction pipe 924, the connecting pipe 925 and the internal cavity of the pressure plate 916. When the fabric passes the bottom of the pressure plate 916, under the action of negative pressure, the dust is forced to enter the collection box 922 through the dust suction hole 921, the internal cavity of the pressure plate 916, the connecting pipe 925 and the air extraction pipe 924 for collection, reducing the interference of dust on the fabric inspection.

[0045] In this invention, during use, the fabric 8 is first wound onto the winding roller 5, and then the fabric 8 is sequentially passed over the guide roller 6 and the top of the inspection table 1 to ensure a smooth conveying path for the fabric 8. The drive motor 7 is then started, and its output drives the winding roller 5 to rotate, thereby providing winding power and allowing the fabric 8 to be conveyed forward on the inspection table 1. At this time, the pressure plate 916 in the fabric pressing and dust filtering assembly 9 initially presses against the upper side of the fabric 8 under the action of gravity, applying a certain basic pressure to the fabric 8, so that the fabric 8 remains initially smooth during conveying. When encountering fabrics of different thicknesses or types, and it is necessary to adjust the pressure of the pressure plate 916 on the fabric 8, the built-in motor 910 is started. The small gear 911 at the output end of the built-in motor 910 meshes with the large gear 99, driving the large gear 99 to rotate, which in turn causes the rotating shaft 94 to rotate. Due to the cooperation of the limiting groove 913 and the limiting strip 95, the sleeve 912 can only rotate with the rotating shaft 94. Unable to move axially, when the sleeve 912 rotates, it drives the pressure plate 916 to rotate via the rotating rod 915, thereby pressing down or lifting the pressure plate 916. For example, when the sleeve 912 is driven to rotate counterclockwise, the pressure plate 916 continues to press down, the spring 919 is stretched, and the return force of the spring 919 gradually increases, applying more suitable pressure to the thinner fabric 8, avoiding incomplete wrinkle removal. During this process, the tension sensor 918 senses the return force on the spring 919 in real time and transmits the data to the controller 3. The controller 3 precisely controls the rotation direction and angle of the built-in motor 910 according to the preset pressure parameters and the received data from the tension sensor 918, thereby precisely controlling the return force of the spring 919. This achieves the purpose of the pressure plate 916 providing appropriate pressure to different fabrics 8, improving the wrinkle removal effect, and keeping the fabric inspected at the bottom of the fabric inspection machine 10 in a smooth state, avoiding fabric inspection errors.
