Description

Technical Field

[0001] This utility model relates to the field of textile testing technology, specifically a foreign object detection mechanism for textile warp knitting machines. Background Technology

[0002] Warp knitting machines are core equipment in the textile industry. They form warp-knitted fabrics by feeding one or more sets of parallel yarns into all the working needles of the machine along the warp direction, simultaneously creating loops. During the warp knitting process, short fibers, knots, metal shavings, and other impurities or foreign objects easily adhere to the surface of the woven fabric. If these foreign objects enter the warp knitting machine along with the woven fabric, they can cause equipment jamming, component wear, and shorten the machine's lifespan. They can also lead to quality problems such as holes and defects in the woven fabric. Therefore, setting up an efficient foreign object detection mechanism at the feed end of the warp knitting machine is crucial to ensuring stable production and product quality.

[0003] Patent application CN212255754U discloses a foreign object detection mechanism for a textile warp knitting machine, including a base. Support plates are symmetrically connected to the upper sidewalls of the base via vertical rods. A sleeve plate is fixedly connected to the lower sidewall of the support plates via a second support rod. A spring is fixedly connected to the inner sidewall of the sleeve plate via a first pad. When a foreign object is detected, the first support rod causes the second pad to move longitudinally. Simultaneously, the second pad causes the first connecting rod to slide within a groove. The first connecting rod then causes the second connecting rod to move upwards. Since the first and second contact points are on the same straight line, the first and second contact points at the top of the second connecting rod come into contact with each other. Because the second contact point is connected to the input of an alarm light and the first contact point is connected to the output of a battery, the input of the alarm light connects to the output of the battery, causing the alarm light to illuminate and removing the foreign object from the fabric.

[0004] However, existing detection mechanisms can only cover the local area where the fabric contacts the first support rod, and cannot cover the edges of the fabric and other non-contact areas, which easily creates detection blind spots. This makes it difficult to identify foreign objects in the edge areas, resulting in missed detections. As a result, the missed foreign objects may still enter the warp knitting machine, causing equipment failure or affecting the quality of the fabric. Therefore, it cannot meet the actual needs of comprehensive fabric inspection. To address the above problems, a foreign object detection mechanism for textile warp knitting machines is proposed. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problem of missed detections in existing testing institutions, this utility model proposes a foreign object detection mechanism for textile warp knitting machines.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a foreign object detection mechanism for a textile warp knitting machine, comprising a housing, wherein support blocks are fixedly connected to the four corners of the bottom of the housing; A through-type detection groove is provided inside the upper part of the housing. Guide rollers are rotatably connected to the upper and lower parts of the left and right sides between the front and rear surfaces of the detection groove. A detection component is provided inside the detection groove. The detection component includes a through slot formed on the upper surface inside the detection groove. A visual inspection camera is installed inside the through slot via a movable component. An audible and visual alarm is fixedly installed on the top left side of the housing, and a controller is fixedly installed on the top right side of the housing. Both the visual inspection camera and the audible and visual alarm are electrically connected to the controller.

[0007] Preferably, the moving component includes a mounting frame disposed inside the through slot via a mounting component. A reciprocating screw is rotatably connected between the front and rear surfaces inside the mounting frame. A sleeve block is threadedly connected to the outer surface of the reciprocating screw. The bottom of the sleeve block is fixedly installed to the top of the vision inspection camera. A motor is fixedly installed on the front surface of the mounting frame. The output end of the motor is fixedly connected to the front end of the reciprocating screw.

[0008] Preferably, a limiting groove is formed on the inner upper surface of the mounting bracket, a limiting block is slidably connected inside the limiting groove, and the bottom of the limiting block is fixedly connected to the top of the sleeve block.

[0009] Preferably, the mounting assembly includes a through groove formed on the upper surface of the through slot, a mounting plate inserted into the groove, the bottom of the mounting plate being fixedly connected to the top of the mounting bracket, and a plurality of mounting bolts passing through the mounting plate, the bottom ends of the mounting bolts being inserted into the housing and threadedly connected to the housing.

[0010] Preferably, both the through groove and the recess are rectangular, and the internal cross-sectional area of ​​the recess is larger than that of the through groove.

[0011] Preferably, handles are fixedly connected to the lower center of both the left and right sides of the housing.

[0012] Preferably, the housing has a through-type storage slot running from front to back.

[0013] The advantages of this utility model are: 1. This utility model uses a motor to drive a reciprocating lead screw to rotate. After the reciprocating lead screw rotates inside the mounting frame, it drives the sleeve block connected to it to move back and forth. The back and forth movement of the sleeve block allows the vision inspection camera to move back and forth for inspection. This allows the detection range of the vision inspection camera to cover the width of the fabric and ensures that the fabric guided by the guide roller through the shell can be detected, thus avoiding missed detections that would affect the subsequent fabric quality.

[0014] 2. This utility model facilitates the disassembly of the mounting plate by means of mounting bolts, and also facilitates the disassembly of the mounting plate and the mounting frame. It also allows the visual inspection camera, which is mounted inside the mounting frame via a sleeve block, to be disassembled from inside the housing for inspection and maintenance. This makes the mechanism more versatile and practical. Attached Figure Description

Detailed Implementation

[0018] 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.

[0019] Example 1 Please see Figure 1-4 As shown, a foreign object detection mechanism for a textile warp knitting machine includes a housing 1, and support blocks are fixedly connected to the four corners of the bottom of the housing 1; The upper part of the housing 1 has a through-type detection groove 7. The upper and lower parts of the left and right sides between the front and rear surfaces of the detection groove 7 are rotatably connected to guide rollers 8. The detection groove 7 is equipped with a detection component. The detection component includes a through groove 17 formed on the upper surface inside the detection slot 7. A visual inspection camera 16 is installed inside the through groove 17 via a movable component. An audible and visual alarm 2 is fixedly installed on the top left side of the housing 1, and a controller 6 is fixedly installed on the top right side of the housing 1. The visual inspection camera 16 and the audible and visual alarm 2 are both electrically connected to the controller 6. During operation, the bottom of the support block is first placed against a flat ground to ensure the stability of the mechanism. The housing 1 is then positioned in front of the feed inlet of the warp knitting machine, with the detection slot 7 corresponding to the feed inlet. Then, the guide roller 8 connected inside the detection slot 7 is rotated to guide the fabric passing through the detection slot 7. The material enters the warp knitting machine and is then visually inspected by the vision inspection camera 16 inside the inspection slot 7. The camera captures images of the target area in real time and transmits them to the controller 6. The controller 6 then performs comparative processing through its internal processing module. When a foreign object is detected, the controller 6 activates the audible and visual alarm 2 to alert the staff to check and handle the issue. These detection methods are conventional techniques in this field and will not be described in detail. The inspection continues after the foreign object is handled. The vision inspection camera 16 can move back and forth via a moving component and can move within the width of the fabric to detect objects, not being limited to a single area. This avoids missed detections and makes the machine easy to use with good performance.

[0020] The moving component includes a mounting frame 10 disposed inside the through slot 17 via an installation assembly. A reciprocating lead screw 13 is rotatably connected between the front and rear surfaces inside the mounting frame 10. A sleeve block 14 is threadedly connected to the outer surface of the reciprocating lead screw 13. The bottom of the sleeve block 14 is fixedly installed to the top of the vision inspection camera 16. A motor 12 is fixedly installed on the front surface of the mounting frame 10. The output end of the motor 12 is fixedly connected to the front end of the reciprocating lead screw 13. During operation, the motor 12 drives the reciprocating lead screw 13 to rotate. After the reciprocating lead screw 13 rotates inside the mounting frame 10, it drives the sleeve block 14, which is threadedly connected to it, to move back and forth. The back and forth movement of the sleeve block 14 allows the vision inspection camera 16 to move back and forth for inspection. This allows the inspection range of the vision inspection camera 16 to cover the width of the fabric and ensures that the fabric guided by the guide roller 8 through the housing 1 can be detected, avoiding missed inspections that would affect the subsequent fabric quality.

[0021] The mounting bracket 10 has a limiting groove 11 on its inner upper surface. A limiting block 15 is slidably connected inside the limiting groove 11. The bottom of the limiting block 15 is fixedly connected to the top of the sleeve block 14. During operation, the movement of the sleeve block 14 is limited by the sliding of the limiting block 15 inside the limiting groove 11, which makes the reciprocating movement of the sleeve block 14 and the visual inspection camera 16 more stable.

[0022] The mounting assembly includes a through groove 3 formed on the upper surface of the through slot 17. A mounting plate 4 is inserted into the groove 3. The bottom of the mounting plate 4 is fixedly connected to the top of the mounting frame 10. Multiple mounting bolts 5 pass through the mounting plate 4. The bottom ends of the mounting bolts 5 are inserted into the housing 1 and threadedly connected to the housing 1. During operation, the mounting bolts 5 facilitate the disassembly of the mounting plate 4 and the mounting frame 10, and also facilitate the disassembly of the vision inspection camera 16 mounted inside the mounting frame 10 via the sleeve block 14. This allows the vision inspection camera 16 to be removed from inside the housing 1 for inspection and maintenance, and enables the mechanism to meet more usage needs and has strong practicality.

[0023] Both the through groove 17 and the recess 3 are rectangular in shape. The internal cross-sectional area of ​​the recess 3 is larger than that of the through groove 17. During operation, the mounting bracket 10 can be moved out of the through groove 17 and through the recess 3 for disassembly, and the visual inspection camera 16 can be disassembled easily.

[0024] Handles 9 are fixedly connected to the lower center of both the left and right sides of the housing 1; during operation, the handles 9 facilitate the handling and relocation of the housing 1, as well as the handling and relocation of the mechanism itself.

[0025] Example 2 Please see Figure 5 As shown in the first embodiment, as another implementation of this utility model, the housing 1 has a front-to-back through storage slot 18 inside; during operation, the storage slot 18 facilitates the storage of items in the housing 1.
