Description

A standard device for detecting the bending of a coil shifting needle Technical Field

[0001] This utility model relates to the field of knitting production technology, specifically to a standard device for detecting and selecting bent loop needles. Background Technology

[0002] The transfer needle, also known as a "double-eye transfer needle" or "somersault needle," is a special type of needle used in knitting machinery. Its main function is to perform knitting operations such as gathering, transferring, jacquard, and intarsia to create patterns with effects like eyelets, raised and recessed areas, and warp twist. The structure of the transfer needle mainly includes the needle bar, spring plate, and needle latch. The spring plate is a unique component of the transfer needle and needs to be installed into a spring plate mounting slot on the needle bar through an installation process. The spring plate is one of the main distinguishing features of the transfer needle from other types of knitting needles and is an essential component for achieving the transfer function.

[0003] Currently, depending on the design requirements of knitted products and the characteristics of the fabric, it is sometimes necessary to perform selective bending of the transfer needles to achieve a specific degree of curvature and shape. This selective bending allows the transfer needles to better adapt to the structure and texture of the fabric during the weaving process, thereby improving weaving efficiency and quality.

[0004] After the transfer needles are processed, they need to be manually placed on the testing equipment and then tested one by one. At the same time, because the difference between qualified and defective products is very small when the transfer needles are tested, it is difficult for the manual to distinguish them in time, which may lead to confusion between qualified and defective products, resulting in low working efficiency of the equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a standard device for detecting the bending of a shift needle, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A standard device for detecting the bending of a coil shifting needle includes a housing, a support column at the top of the housing, an electric push rod fixedly connected to the support column, a support plate fixedly connected to the output end of the electric push rod, a pressure rod and a sensor fixedly connected to the support plate, a collection box slidably connected to the bottom of the housing, a handle fixedly connected to the collection box, a detection plate inside the housing, the detection plate being rotatably connected to the housing, an adjustment component for adjusting the detection plate on one side of the housing, a limiting component for limiting the position of the detection plate on the side of the housing near the detection component, a delay component for fixing the detection plate inside the housing, and a control panel fixedly connected to the outside of the housing, the control panel being electrically connected to the electric push rod and the sensor respectively.

[0008] When the transfer needle needs to be tested, it is placed on the testing plate, and then tested by a sensor located above the testing plate. If the test is qualified, the electric push rod will drive the support plate fixedly connected to its output end to move the pressure rod, thereby adjusting the angle of the testing plate by the adjustment component. Before the testing plate rotates, the limiting component will release the limiting component on the testing plate, causing the transfer needle to fall into the collector located below the testing plate. Each time the testing plate is adjusted, it will rotate one revolution. If the test is unqualified, it can be removed manually, thus avoiding confusion between qualified and defective products during testing.

[0009] A further improvement of this utility model's technical solution is that: the adjusting component includes a gear and a rack; a sliding groove is provided inside the housing; the rack is slidably connected to the sliding groove; a pressure spring is fixedly connected to the lower end of the rack; the other end of the pressure spring is fixedly connected to the housing; a rotating shaft is rotatably connected inside the housing; the gear is connected to the rotating shaft via a one-way bearing; a pulley is fixedly connected to one end of the rotating shaft; a pulley is fixedly connected to the end of the detection plate near the rack; the pulleys are connected by a belt drive; the gear meshes with the rack; and a pressure plate is fixedly connected to the upper end of the rack.

[0010] In the above technical solution, when the pressure rod moves, it presses against the pressure plate, causing the rack to move along the length of the slide groove. At this time, the pressure spring is in a compressed state, and the gear rotates. However, under the action of the one-way bearing, the rotating shaft does not rotate. When the pressure rod presses the rack to a certain distance, the electric push rod resets, and the pressure rod moves in the opposite direction. At this time, under the force of the pressure spring, the rack moves in the opposite direction, thereby driving the rotating shaft to rotate through the one-way bearing and the gear. The rotation of the rotating shaft will transmit power to the detection plate through the cooperation between the pulley and the belt, thereby achieving the purpose of driving the detection plate to rotate and collect qualified transfer needles.

[0011] A further improvement of this utility model's technical solution is that: the limiting component includes a moving rod, which is slidably connected to the housing; a fixing groove is provided on the detection plate, and the moving rod cooperates with the fixing groove; a slider and a housing are respectively provided at the end of the moving rod away from the detection plate; the slider is fixedly connected to the moving rod; the housing is fixedly connected to the housing; a groove is provided inside the housing; the slider is slidably connected to the groove; a moving plate is fixedly connected to the moving rod; a spring is fixedly connected to the side of the moving plate near the detection plate; the other end of the spring is fixedly connected to the housing; and an inclined surface is provided at the end of the slider away from the moving rod.

[0012] In the above technical solution, when the detection plate is not rotating, the moving rod is located inside the fixed groove, limiting the detection plate. When the detection plate needs to rotate, the rack moves downward. At this time, the pressure plate no longer supports the delay component, causing the delay component to move downward. Under the force of the spring spring, the moving rod moves away from the detection plate, thereby releasing the support for the detection plate. When the pressure plate moves upward, it presses the delay component to enable the limiting component to perform a delay limiting on the detection plate.

[0013] A further improvement of the present invention is that the delay component includes a piston cylinder and a delay assembly. The piston cylinder is slidably connected to the groove. A through hole is provided on the piston cylinder. A piston plate is slidably connected inside the piston cylinder. A piston rod is fixedly connected to the side of the piston plate away from the through hole. A top plate is fixedly connected to the side of the piston rod away from the piston plate. A return spring is fixedly connected to the other end of the piston plate away from the piston rod. The other end of the return spring is fixedly connected to the piston cylinder.

[0014] In the above technical solution, when the pressure plate moves downward, the piston rod moves downward, and the return spring in the piston cylinder is in a normal state. When the pressure plate moves upward, it will press against the top plate, and the piston cylinder is in a fixed state under the action of the delay component. At this time, the return spring is in a compressed state. When the rack is reset, the delay component releases the piston cylinder from the fixation, and the piston cylinder moves upward under the force of the return spring, thereby moving the limit rod to limit the detection plate.

[0015] A further improvement of the present invention is that the delay component includes a sliding block, a moving groove is provided on the pressure rod, the sliding block is slidably connected to the moving groove, a limiting groove is provided in the housing, a delay block is slidably connected in the limiting groove, a delay hole is provided on the delay block, the delay block is used in conjunction with the sliding block, a delay spring is fixedly connected to one end of the delay block away from the sliding block, and the other end of the delay spring is fixedly connected to the housing.

[0016] In this technical solution, when the pressure rod moves downward, it presses against the pressure plate. The delay block drives the sliding block to slide within the moving groove. When the sliding block reaches one end and is fixed, the piston cylinder moves downward. The sliding block then presses against the delay spring via the delay block, compressing the spring. The delay block then prevents the piston cylinder from moving upward. When the pressure rod moves upward, the sliding block, under the frictional force between the delay block and the sliding block, moves along the moving groove to the other end until it is fixed. The pressure plate then presses against the top plate, compressing the return spring within the piston cylinder. When the sliding block on one side of the pressure rod disengages from the delay block, the delay spring resets. Under the spring's force, the piston cylinder passes through the delay hole and drives the limiting rod to limit the detection plate. This achieves the purpose of time-delay limiting.

[0017] A further improvement of this utility model is that an inclined block is fixedly connected to the end of the piston cylinder away from the pressure plate.

[0018] By adopting the above technical solution, the tilting block can better match the slider and the delay component during operation, while preventing excessive wear and thus extending the service life of the slider.

[0019] A further improvement of this utility model is that the end of the delay block that contacts the sliding block is provided with a rounded corner.

[0020] By adopting the above technical solution, the use of rounded corners can prevent wear caused by the sliding block on the delay block during operation, thus preventing damage to the delay component.

[0021] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0022] 1. This utility model provides a standard device for detecting the bending of a bobbin transfer needle. When the bobbin transfer needle needs to be tested, it is placed on a testing plate. Then, a sensor located above the testing plate tests the bobbin transfer needle. If the test is qualified, the electric push rod will drive the support plate fixedly connected to its output end to move the pressure rod. The angle of the testing plate is adjusted by the adjustment component. Before the testing plate rotates, the limiting component will release the limiting component on the testing plate, causing the bobbin transfer needle to fall into the collector located below the testing plate. The testing plate will rotate one revolution each time it is adjusted. If the test is unqualified, it can be removed manually, thereby avoiding confusion between qualified and defective products during testing.

[0023] 2. This utility model provides a standard device for detecting the bending of a coil shifting needle. When the pressure plate moves downward, the piston rod moves downward, and the return spring in the piston cylinder is in a normal state. When the pressure plate moves upward, the pressure plate will press the top plate. At this time, the piston cylinder is in a fixed state under the action of the delay component, and the return spring is in a compressed state. When the rack returns to its original position, the delay component releases the fixation of the piston cylinder, and the piston cylinder moves upward under the force of the return spring, thereby moving the limit rod to limit the detection plate.

[0024] 3. This utility model provides a standard device for detecting the bending of a coil shifting needle. When the pressure rod moves downward, it presses against the pressure plate. The delay block drives the sliding block to slide within the moving groove. When the sliding block moves to one end and is fixed, the piston cylinder moves downward. The sliding block presses against the delay spring through the delay block, causing the delay spring to be in a compressed state. At this time, the delay block prevents the piston cylinder from moving upward. When the pressure rod moves upward, the sliding block moves along the moving groove to the other end until it is fixed under the frictional force between the delay block and the sliding block. Then, the pressure plate presses against the top plate, causing the return spring in the piston cylinder to be in a compressed state. When the sliding block on one side of the pressure rod disengages from the delay block, the delay spring resets. Under the force of the spring, the piston cylinder passes through the delay hole and then drives the limiting rod to limit the detection plate. This achieves the purpose of delay and limiting.

Detailed Implementation

[0033] The present invention will be further described in detail below with reference to embodiments: Embodiments

[0034] As shown in Figures 1 and 2, this utility model provides a standard device for detecting the bending of a coil shifting needle, including a housing 1. A support column 2 is provided on the top of the housing 1, and an electric push rod is fixedly connected to the support column 2. A support plate 3 is fixedly connected to the output end of the electric push rod. A pressure rod 4 and a sensor are fixedly connected to the support plate 3. A collection box 5 is slidably connected to the lower end of the housing 1, and a handle is fixedly connected to the collection box 5. A detection plate 6 is provided inside the housing 1 and is rotatably connected to the housing 1. An adjustment component for adjusting the detection plate 6 is provided on one side of the housing 1. A limiting component for limiting the position of the detection plate 6 is provided on the side of the housing 1 near the detection component. A delay component for fixing the detection plate 6 is provided inside the housing 1. A control panel is fixedly connected to the outside of the housing 1. The control panel is electrically connected to the electric push rod and the sensor.

[0035] In this embodiment, when the transfer needle needs to be tested, the transfer needle is placed on the test plate 6, and then the sensor located above the test plate 6 tests the transfer needle. If the test is qualified, the electric push rod will drive the support plate 3, which is fixedly connected to its output end, to move the pressure rod 4, thereby adjusting the angle of the test plate 6 through the adjustment component. Before the test plate 6 rotates, the limiting component will release the limiting of the test plate 6, so that the transfer needle falls into the collector located below the test plate 6. Each time the test plate 6 is adjusted, it will rotate one revolution. If the test is unqualified, it can be removed manually, thereby avoiding confusion between qualified and defective products during the test.

[0036] As shown in Figure 3, in this embodiment, preferably, the adjusting component includes a gear 7 and a rack 8. A groove 9 is provided inside the housing 1, and the rack 8 is slidably connected to the groove 9. A pressure spring 10 is fixedly connected to the lower end of the rack 8, and the other end of the pressure spring 10 is fixedly connected to the housing 1. A rotating shaft 11 is rotatably connected inside the housing 1. The gear 7 is connected to the rotating shaft 11 through a one-way bearing. A pulley is fixedly connected to one end of the rotating shaft 11. A pulley is fixedly connected to the end of the detection plate 6 near the rack 8. The pulleys are connected by a belt drive. The gear 7 meshes with the rack 8, and a pressure plate 12 is fixedly connected to the upper end of the rack 8.

[0037] When the pressure rod 4 moves, it presses the pressure plate 12, causing the rack 8 to move along the length of the slide groove 9. At this time, the pressure spring 10 is in a compressed state, and the gear 7 rotates. However, under the action of the one-way bearing, the rotating shaft 11 does not rotate. When the pressure rod 4 presses the rack 8 to a certain distance, the electric push rod resets, and the pressure rod 4 moves in the opposite direction. At this time, under the force of the pressure spring 10, the rack 8 moves in the opposite direction, thereby driving the rotating shaft 11 to rotate through the one-way bearing and the gear 7. The rotation of the rotating shaft 11 will transmit power to the detection plate 6 through the cooperation between the pulley and the belt, thereby achieving the purpose of driving the detection plate 6 to rotate and collect qualified transfer needles.

[0038] As shown in Figure 6, preferably, the limiting component includes a moving rod 13, which is slidably connected to the housing 1. A fixing groove 14 is provided on the detection plate 6, and the moving rod 13 is used in conjunction with the fixing groove 14. A slider 15 and a housing 16 are respectively provided at the end of the moving rod 13 away from the detection plate 6. The slider 15 is fixedly connected to the moving rod 13, and the housing 16 is fixedly connected to the housing 1. A groove 17 is provided in the housing 16, and the slider 15 is slidably connected to the groove 17. A moving plate 18 is fixedly connected to the moving rod 13. A spring spring 19 is fixedly connected to the side of the moving plate 18 near the detection plate 6. The other end of the spring spring 19 is fixedly connected to the housing 1. An inclined surface 20 is provided at the end of the slider 15 away from the moving rod 13.

[0039] When the detection plate 6 is not rotating, the moving rod 13 is located inside the fixed groove 14, limiting the detection plate 6. When the detection plate 6 needs to rotate, the rack 8 moves downward. At this time, the pressure plate 12 no longer supports the delay component, causing the delay component to move downward. Under the force of the spring spring 19, the moving rod 13 moves away from the detection plate 6, thereby releasing the support for the detection plate 6. When the pressure plate 12 moves upward, it presses the delay component to enable the limiting component to delay and limit the detection plate 6.

[0040] As shown in Figure 5, preferably, the delay component includes a piston cylinder 21 and a delay assembly. The piston cylinder 21 is slidably connected to the groove 17. A through hole is provided on the piston cylinder 21. A piston plate 22 is slidably connected inside the piston cylinder 21. A piston rod 23 is fixedly connected to the side of the piston plate 22 away from the through hole. A top plate 24 is fixedly connected to the side of the piston rod 23 away from the piston plate 22. A return spring 25 is fixedly connected to the other end of the piston plate 22 away from the piston rod 23. The other end of the return spring 25 is fixedly connected to the piston cylinder 21.

[0041] When the pressure plate 12 moves downward, the piston rod 23 moves downward. At this time, the return spring 25 in the piston cylinder 21 is in the normal state. When the pressure plate 12 moves upward, the pressure plate 12 will press the top plate 24. At this time, the piston cylinder 21 is in a fixed state under the action of the delay component. At this time, the return spring 25 is in a compressed state. When the rack 8 is reset, the delay component releases the fixation of the piston cylinder 21. The piston cylinder 21 moves upward under the force of the return spring 25, thereby moving the limit rod to limit the detection plate 6.

[0042] As shown in Figure 5, preferably, the delay component includes a sliding block 26, a moving groove is provided on the pressure rod 4, the sliding block 26 is slidably connected to the moving groove, a limiting groove 28 is provided in the housing 16, a delay block 29 is slidably connected in the limiting groove 28, a delay hole 30 is provided on the delay block 29, the delay block 29 is used in conjunction with the sliding block 26, a delay spring 31 is fixedly connected to one end of the delay block 29 away from the sliding block 26, and the other end of the delay spring 31 is fixedly connected to the housing 16.

[0043] When the pressure rod 4 moves downward, it presses against the pressure plate 12. The delay block 29 drives the sliding block 26 to slide within the moving groove. When the sliding block 26 moves to one end and is fixed, the piston cylinder 21 moves downward. The sliding block 26 presses against the delay spring 31 through the delay block 29, causing the delay spring 31 to be in a compressed state. At this time, the delay block 29 prevents the piston cylinder 21 from moving upward. When the pressure rod 4 moves upward, the sliding block 26 moves along the moving groove to the other end until it is fixed under the frictional force between the delay block 29 and the sliding block 26. Then, the pressure plate 12 presses against the top plate 24, causing the return spring 25 inside the piston cylinder 21 to be in a compressed state. When the sliding block 26 on one side of the pressure rod 4 disengages from the delay block 29, the delay spring 31 resets. Under the force of the spring, the piston cylinder 21 passes through the delay hole 30 and then drives the limiting rod to limit the detection plate 6. This achieves the purpose of delay and limiting.

[0044] As shown in Figure 5, preferably, an inclined block 32 is fixedly connected to the end of the piston cylinder 21 away from the pressure plate 12.

[0045] By incorporating the tilt block 32, better coordination between the slider 15 and the delay component can be achieved during operation, while preventing excessive wear and extending the service life of the slider 15.

[0046] As shown in Figure 1, preferably, the end of the delay block 29 that contacts the sliding block 26 is provided with a rounded corner.

[0047] The use of rounded corners can prevent wear on the delay block 29 caused by the sliding block 26 during operation, thus preventing damage to the delay component.

[0048] The working principle of this type of standard equipment for detecting bending of the coil shifting needle will be explained in detail below.

[0049] As shown in Figure 1-6, when the transfer needle needs to be tested, the transfer needle is placed on the test plate 6, and then the sensor located above the test plate 6 tests the transfer needle. If the test is qualified, the electric push rod will drive the support plate 3, which is fixedly connected to its output end, to move the pressure rod 4, thereby adjusting the angle of the test plate 6 through the adjustment component. Before the test plate 6 rotates, the limiting component will release the limiting component on the test plate 6, so that the transfer needle falls into the collector located below the test plate 6. Each time the test plate 6 is adjusted, it will rotate one revolution. If the test is unqualified, it can be removed manually, thereby avoiding confusion between qualified and defective products during the test. When the pressure rod 4 moves, it presses against the pressure plate 12, causing the rack 8 to move along the length of the slide groove 9. At this time, the pressure spring 10 is compressed, and the gear 7 rotates. However, under the action of the one-way bearing, the rotating shaft 11 does not rotate. When the pressure rod 4 presses the rack 8 to a certain distance, the electric push rod resets, and the pressure rod 4 moves in the opposite direction. At this time, under the force of the pressure spring 10, the rack 8 moves in the opposite direction, thereby driving the rotating shaft 11 to rotate through the one-way bearing and the gear 7. The rotation of the rotating shaft 11 transmits power to the detection plate 6 through the cooperation between the pulley and the belt. When the detection plate 6 does not rotate, the moving rod 13 is located inside the fixed groove 14, limiting the detection plate 6. When the detection plate 6 needs to rotate, the rack 8 moves downward. At this time, the pressure plate 12 no longer supports the delay component, causing the delay component to move downward. At this time, under the force of the spring spring 19, the moving rod 13 moves away from the detection plate 6, thereby releasing the support of the detection plate 6. When the pressure plate 12 moves upward, it presses the delay component to allow the limiting component to delay and limit the detection plate 6. When the pressure plate 12 moves downward, the piston rod 23 moves downward, and the return spring 25 in the piston cylinder 21 is in its normal state. When the pressure plate 12 moves upward, it presses the top plate 24, and the piston cylinder 21 is fixed under the action of the delay component. At this time, the return spring 25 is in a compressed state. When the rack 8 returns to its original position, the delay component releases the piston cylinder 21 from its fixed position, and the piston cylinder 21 moves upward under the force of the return spring 25, thereby moving the limiting rod to limit the detection plate 6.When the pressure rod 4 moves downward, it presses against the pressure plate 12. The delay block 29 drives the sliding block 26 to slide within the moving groove. When the sliding block 26 moves to one end and is fixed, the piston cylinder 21 moves downward. The sliding block 26 presses against the delay spring 31 through the delay block 29, causing the delay spring 31 to be in a compressed state. At this time, the delay block 29 prevents the piston cylinder 21 from moving upward. When the pressure rod 4 moves upward, the sliding block 26 moves along the moving groove to the other end until it is fixed under the frictional force between the delay block 29 and the sliding block 26. Then, the pressure plate 12 presses against the top plate 24, causing the return spring 25 inside the piston cylinder 21 to be in a compressed state. When the sliding block 26 on one side of the pressure rod 4 disengages from the delay block 29, the delay spring 31 resets. Under the force of the spring, the piston cylinder 21 passes through the delay hole 30 and then drives the limiting rod to limit the detection plate 6. This achieves the purpose of delay and limiting. The tilting block 32 allows for better coordination between the slider 15 and the delay component during operation, while preventing excessive wear and extending the service life of the slider 15. The rounded corners reduce wear on the delay block 29 caused by the slider 26 during operation, preventing damage to the delay assembly.

[0050] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
