[0002] In the process of sock weaving, a needle cylinder device for sleeve sock bodies is required. The needle cylinder device mainly includes two parts: a needle cylinder as an installation body with a plurality of slots and a thin and long strip-shaped insert that is inserted and fixed in these slots.

DETAILED DESCRIPTION

[0027] The embodiment of the present invention provides a socks needle pressing mechanism, such as Figure 1-5 As shown, the needle is inserted into the slot of the syringe 1, which includes multiple ferrules 2 and multiple slide bars 6. The multiple ferrules 2 are arranged up and down, and the multiple slide bars 6 are installed inside the ferrules 2. The multiple slide bars 6 are arranged up and down, and a connecting strip 3 is welded between two adjacent ferrules 2. A positioning component 5 is provided on the side of the connecting strip 3 away from the ferrule 2. The positioning component 5 is used to align the needle with the slot of the syringe 1.

[0028] The slide bar 6 is slidably matched with the insertion pin, and the insertion pin slides out from the slide bar 6 and enters the slot of the syringe 1.

[0029] A pin test assembly is fixedly installed on one side of the connecting strip 3 to detect whether the pin is bent. The test assembly includes a laser transmitter 33, multiple laser receivers 34 and multiple air outlet pipes 35. Multiple grooves 32 are opened from top to bottom on the right side of the connecting strip 3. The laser transmitter 33 and the laser receiver 34 are fixedly installed in the grooves 32. The laser receivers 34 are distributed around the laser transmitter 33. The laser transmitter 33 emits horizontal laser lines outward.

[0030] The surface of the pin is coated with a reflective coating. Working principle: The side of the connecting strip 3 is a vertical plane. When the pin slides out from the slide bar 6, the pin contacts the side of the connecting strip 3. If the pin is vertical and not deformed, the pin is close to the side of the connecting strip 3, and the laser emitter 33 emits a horizontal laser line outward, and the laser line is reflected back horizontally through the pin.

[0031] When the pin is bent due to deformation, the laser line is deflected by the pin, and the light is captured by the laser receiver 34, which feeds back the information to the computer terminal. The computer terminal controls the device to stop working.

[0032] A plurality of air outlet pipes 35 are fixedly installed at equal distances in the connecting strip 3 , and the right end of the air outlet pipe 35 extends outside the connecting strip 3 . The air outlet pipe 35 can spray out recognizable red smoke.

[0033] When the straight pin contacts the side of the connecting strip 3, the pin blocks the air outlet pipe 35. When the deformed and bent pin contacts the connecting strip 3, there is a gap between the pin and the connecting strip 3, and the red smoke leaks from the gap, which is convenient for workers to observe.

[0034] When the above components are working, the staff sees smoke leakage and the computer terminal receives information fed back by the laser receiver 34. When both conditions are met, it is determined that the pin is deformed.

[0035] The positioning assembly 5 comprises an upper block 51, a lower block 52, a vertical rotating rod 54 and a vertical clamping strip 55. The upper block 51 is located directly above the lower block 52, and a steel plate is welded between the upper block 51 and the lower block 52. The block is welded to the ferrule 2.

[0036] The upper end of the rotating rod 54 passes through the lower block 52 and is pivotally connected to the upper block 51 , and the lower end of the rotating rod 54 is welded to the clamping strip 55 . A gear ring 11 is fixedly installed on the top of the syringe 1 , and the gear ring 11 and the syringe 1 are arranged in concentric circles.

[0037] The tooth grooves of the tooth ring 11 correspond to the slots of the syringe 1 one by one. The cross section of the clamping strip 55 is in a "cross" shape, and the end of the rotating rod 54 can be clamped into the tooth grooves of the tooth ring 11.

[0038] It also includes an elastic rope 53, a tension sensor unit 56, and a rubber rod 57. The tension sensor unit 56 is fixedly installed on the opposite sides of the upper block 51 and the lower block 52, the end of the elastic rope 53 is fixedly tied to the working end of the tension sensor unit 56, and the rubber rod 57 is annularly distributed and fixedly installed outside the shaft of the rotating rod 54, and the shaft of the rubber rod 57 can contact the elastic rope 53.

[0039] The four rubber rods 57 are in the same horizontal plane, and the angle between two adjacent rubber rods 57 is 90°. The rubber rods 57 correspond to the ends of the clamping strips 55 one by one, and the rubber rods 57 have a certain toughness.

[0040] When the needle cylinder 1 rotates around the axis, the toothed ring 11 is driven to rotate. When the elastic rope 53 is pulled to the limit, the rubber rod 57 is driven to bend. After the rubber rod 57 is bent, it passes through the elastic rope 53, and the rotating rod 54 rotates 90°, so that the clamping strip 55 is clamped into the tooth groove of the subsequent toothed ring 11.

[0041] The slide bar 6 is in an arc shape, and a spring 61 is sleeved on the slide bar 6. The right end of the spring 61 is also matched with a slider 7. The left end of the slide bar 6 is welded to the left side of the connecting strip 3. There is a gap 62 between the right end of the slide bar 6 and the right side of the connecting strip 3. The spacing of the gap 62 is adapted to the thickness of the pin. The gap 62 facilitates the pin to move downward.

[0042] The slide bar 6 passes through the slider 7, and a small pressure wheel 71 driven by a motor is pivoted on the upper end of the slider 7. The small pressure wheel 71 is used to contact the pin, and the rotation of the small pressure wheel 71 drives the pin to descend. The pin is provided with a hole that matches the slide bar 6, so that the pin can slide along the slide bar 6.

[0043] A smoke injection hole 31 is provided on the top of the connecting strip 3 , and the smoke injection hole 31 is used for connecting to a smoke injection device. The lower end of the smoke injection hole 31 is connected to the left end of an air outlet pipe 35 , and the air outlet pipe 35 is located below the groove 32 .

[0044] It also includes an electric push rod 4, which is vertically arranged above the connecting strip 3, the lower end of the electric push rod 4 is welded to the upper end of the connecting strip 3, and a motor is fixedly installed at the center of the bottom of the syringe 1. The entire needle pressing mechanism is controlled to rise and fall by telescoping the electric push rod 4.

[0045] In summary, the knitting socks needle pressing mechanism has a ring 2 set above the needle cylinder 1, a connecting strip 3 and a slide bar 6 are installed in the ring 2, and a laser emitter 33, a laser receiver 34 and an air outlet pipe 35 are set on the side of the connecting strip 3. Whether the needle is straight is determined according to whether the emitted laser is captured by the laser receiver 34 and whether smoke leaks from the air outlet pipe 35. It plays the role of detecting whether the needle is straight, so as to achieve the purpose of notifying the worker in time.
