Description

Technical Field

[0001] This utility model relates to the field of horizontal knitting machine technology, and in particular to a probe device for a fully computerized horizontal knitting machine. Background Technology

[0002] The probe device of a flat knitting machine is a crucial component. It primarily detects and identifies the position, condition, or errors of the yarn during the knitting process, monitoring the yarn's status in real time to ensure it is in the correct position and moves along a predetermined path. This helps prevent yarn breakage, misalignment, or other errors, guaranteeing smooth knitting and product quality. With the continuous development and innovation of textile technology, the probe devices of fully computerized flat knitting machines are constantly being improved and upgraded. Some advanced probe devices have higher sensitivity and accuracy, better adapting to complex knitting needs and stricter quality requirements. Simultaneously, some new probe devices have introduced intelligent and automated technologies, such as automatic calibration, automatic detection, and automatic alarm functions, further improving the automation level and production efficiency of the knitting process. This is of great significance for ensuring smooth knitting and product quality. However, existing probe devices detect the presence or absence of yarn through physical contact. When the yarn passes through the probe, the probe senses the change in yarn tension or pressure. The sensor then judges the state of the yarn. However, the sensor is easily affected by factors such as temperature and humidity during use, which affects the sensitivity and accuracy of yarn detection. Furthermore, existing probes are usually set to multiple groups, which is inconvenient for use in flat knitting machines with a large or small amount of yarn, and there are certain drawbacks in the process of use.

[0003] In view of the above, this utility model is hereby proposed. Utility Model Content

[0004] To overcome the technical defects of the existing technology, this utility model provides a probe device for a fully computerized flat knitting machine. It can add or remove probe rods on the horizontal slide rail to detect different quantities of braided wires, making it more flexible and convenient to use. It can judge the state of the braided wire based on the presence or absence of the electrical signal of the piezoelectric sheet, effectively improving the accuracy of braided wire detection, and avoiding any impact on the positioning and installation of the probe rods.

[0005] The technical solution adopted by this utility model is as follows: it includes a mounting plate, on which the transverse slide rail is fixedly mounted, and the self-positioning connecting component is slidably mounted on the transverse slide rail. The probe rod that supports the braided wire is rotatably mounted on the self-positioning connecting component. A limiting slide groove is formed on the mounting plate, and the lifting adjustment component is installed in the limiting slide groove. The piezoelectric sheet is installed on the lifting adjustment component and is located on one side of the probe rod.

[0006] Preferably, in order to enable the probe rod to rotate on the connecting post via the connector, the self-positioning connection assembly includes the connecting slider, the connecting slider being slidably engaged with the transverse slide rail, the connecting seat being fixedly installed on the side wall of the connecting slider, the connecting post being fixedly installed on the top of the connecting seat, and the probe rod being rotatably mounted on the connecting post via the connector.

[0007] Preferably, in order to fix the connecting slider on the transverse slide rail by means of the positioning pin, the top of the connecting slider is fixedly installed with the U-shaped mounting base, and the positioning pin is slidably inserted into the U-shaped mounting base. One end of the positioning pin is inserted into the positioning pin hole correspondingly opened on the connecting slider and the transverse slide rail.

[0008] Preferably, in order to enable the positioning pin to slide on the connecting seat via the lifting drive handle, the lifting drive handle is fixedly installed on the top of the positioning pin.

[0009] Preferably, in order to enable the annular connecting block to drive the positioning pin rod to be fixedly inserted into the positioning pin hole by means of the positioning spring, the annular connecting block is fixedly sleeved on the positioning pin rod, and the annular connecting block is elastically connected to the inner wall of the U-shaped mounting base by means of the positioning spring.

[0010] Preferably, in order to enable the drive screw to rotate in the limiting slide groove via the rotary joint by controlling the servo motor to turn on, the lifting adjustment assembly includes the servo motor and the drive screw. The servo motor is fixed on the inner wall of one end of the limiting slide groove, and the drive screw is rotatably mounted on the inner wall of the other end of the limiting slide groove via the rotary joint. One end of the drive screw is fixedly connected to the output shaft of the servo motor.

[0011] Preferably, in order to drive the threaded slider to slide in the limiting groove by controlling the rotation of the drive screw, the threaded slider is mounted on the drive screw, and the threaded slider is slidably engaged in the limiting groove.

[0012] Preferably, in order to control the threaded slider to slide in the limiting groove, the L-shaped connecting rod can drive the rake-shaped mounting bracket to move up and down. The L-shaped connecting rod is fixedly installed on the threaded slider, and the rake-shaped mounting bracket is fixedly installed at one end of the L-shaped connecting rod. The piezoelectric sheet is fixed on the rake-shaped mounting bracket.

[0013] The beneficial effects of this utility model are as follows: The self-positioning connection component allows the probe rod to be positioned and installed on the transverse slide rail, while also enabling the addition or removal of probe rods on the transverse slide rail to detect different quantities of braided wire. This makes the use more flexible and convenient. Simultaneously, the lifting adjustment component moves the piezoelectric plate to one side of the probe rod, converting the force exerted by the braided wire on the probe rod into an electrical signal. The presence or absence of the piezoelectric signal allows for the determination of the braided wire's state, effectively improving the accuracy of braided wire detection. Furthermore, it avoids affecting the positioning and installation of the probe rod, making it more practical. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1-5As shown, this embodiment provides a probe device for a fully computerized flat knitting machine, including a mounting plate 1. A transverse slide rail 2 is fixedly mounted on the mounting plate 1. A self-positioning connecting component 3 is slidably mounted on the transverse slide rail 2. A probe rod 4 for supporting the knitting yarn is rotatably mounted on the self-positioning connecting component 3. In use, according to the number of knitting yarns, a number of self-positioning connecting components 3 adapted to the number of yarns are added to fix the probe rods 4 on the transverse slide rail 2, so that the number of probe rods 4 is equal to the number of knitting yarns. The knitting yarn is formed by the probe rods 4. A limiting groove is formed on the mounting plate 1. A lifting adjustment assembly 5 is installed, on which a piezoelectric plate 6 is mounted. The piezoelectric plate 6 is located on one side of the probe rod 4. The lifting adjustment assembly 5 is controlled to move the piezoelectric plate 6 up and down, avoiding interference with the installation of the probe rod 4 on the transverse slide rail 2. At the same time, it is convenient to keep the piezoelectric plate 6 on one side of the probe rod 4. When the braided wire applies force to the probe rod 4, the probe rod 4 can apply force through the piezoelectric plate 6, converting the mechanical force of the probe rod 4 into an electrical signal. When the electrical signal of the piezoelectric plate 6 disappears, it can be determined that the braided wire has a fault, making the repair and replacement of the braided wire more timely and convenient.

[0022] The self-positioning connection assembly 3 includes a connecting slider 301, which is slidably engaged with the transverse slide rail 2. A connecting seat 302 is fixedly installed on the side wall of the connecting slider 301, and a connecting post 303 is fixedly installed on the top of the connecting seat 302. A probe rod 4 is rotatably mounted on the connecting post 303 via a connector 304. A U-shaped mounting seat 305 is fixedly installed on the top of the connecting slider 301, and a positioning pin 306 is slidably inserted into the U-shaped mounting seat 305. One end of the positioning pin 306 is inserted into the corresponding positioning pin holes on the connecting slider 301 and the transverse slide rail 2. A lifting drive handle 307 is fixedly installed on the top of the positioning pin 306. A ring-shaped connecting block 308 is fixedly connected to the inner wall of the U-shaped mounting base 305 via a positioning spring 309. In use, by pulling the drive handle 307, the connecting slider 301 is slidably mounted on the transverse slide rail 2. The number of connecting blocks can be increased or decreased according to the number of braided threads, so that the number of probe rods 4 on the transverse slide rail 2 is the same as the number of braided threads, making the use more flexible and meeting different usage conditions. At the same time, under the action of the positioning spring 309 and the ring-shaped connecting block 308, the positioning pin 306 is fixedly inserted into the positioning pin hole, so as to fix the connecting slider 301 on the transverse slide rail 2 and realize the positioning of the probe rod 4.

[0023] The lifting adjustment assembly 5 includes a servo motor 501 and a drive screw 502. The servo motor 501 is fixed on the inner wall of one end of the limiting slide groove. The drive screw 502 is rotatably mounted on the inner wall of the other end of the limiting slide groove via a rotary joint 503, and one end of the drive screw 502 is fixedly connected to the output shaft of the servo motor 501. A threaded slider 504 is mounted on the drive screw 502, and the threaded slider 504 is slidably engaged in the limiting slide groove. An L-shaped connecting rod 505 is fixedly mounted on the threaded slider 504, and one end of the L-shaped connecting rod 505 is fixed... The rake-shaped mounting bracket 506 is installed, and the piezoelectric sheet 6 is fixed on the rake-shaped mounting bracket 506. In use, the servo motor 501 is turned on, so that the drive screw 502 rotates in the limit slide groove through the rotary joint 503, driving the threaded slider 504 to slide in the limit slide groove, so that the rake-shaped mounting bracket 506 can be moved up and down through the L-shaped connecting rod 505, thereby making the piezoelectric sheet 6 located on one side of the probe rod 4, and the rake-shaped mounting bracket 506 can be moved to one side to avoid affecting the positioning and installation of the probe rod 4 on the transverse slide rail 2.
