[0027] Please refer to Figures 1 to 5, the edge tearing and fixing device for a stenter provided by the present utility model will be described hereinafter. The edge tearing and fixing device for a stenter includes a frame 10, a drying member 20, two conveying chains 30, two main brush wheels 40, and two blowing members 50. A conveying cavity 11 extending horizontally to the front and rear ends of the frame 10 is provided at the top of the frame 10; the drying member 20 is arranged on the top of the frame 10 for drying the stented knitted fabric; the two conveying chains 30 are arranged in the conveying cavity 11 along the front-rear direction and are respectively close to the two opposite inner side walls of the conveying cavity 11. Fixing needles 32 extending outward from the conveying chains 30 are provided on the adjacent sides of the two conveying chains 30 for fixing the torn edges; the two main brush wheels 40 are rotatably connected to the top of the frame 10 and are located behind the drying member 20. The main shafts of the main brush wheels 40 extend in the left-right direction, and the two main brush wheels 40 are arranged in one-to-one correspondence with the two conveying chains 30 for rotationally pressing down the torn edges so that the fixing needles 32 penetrate into the torn edges; the two blowing members 50 are arranged on the top of the frame 10 and are arranged in one-to-one correspondence with the two main brush wheels 40. The blowing member 50 has a nozzle 51 located in front of the main brush wheel 40 for blowing down the torn edges so that the fixing needles 32 penetrate deeper into the torn edges.

[0028] The main brush wheel 40 is located above the needle plate 31.

[0029] In the actual use process of the edge tearing and fixing device for a stenter provided in the embodiment of the present application, first, the torn edges on both sides at the input end of the knitted fabric are pre-fixed on the fixing needles 32 on the corresponding sides at the rear of the frame 10. The conveying chain 30 conveys the knitted fabric forward. When the knitted fabric passes through the main brush wheel 40, the main brush wheel 40 rotates and presses down the torn edge, so that the fixing needle 32 penetrates into the torn edge. Then, it passes through the blowing member 50, and the nozzle 51 blows air at the torn edge into which the fixing needle 32 is inserted, so that the fixing needle 32 further penetrates deeply into the torn edge, preventing the torn edge from detaching from the fixing needle 32. Finally, the conveying chain 30 drives the knitted fabric into the drying member 20, and the drying member 20 dries and shapes it, ensuring the shaping effect.

[0030] Compared with the prior art, in the edge tearing and fixing device for a stenter provided in this embodiment, when the knitted fabric passes through the main brush wheel 40, the main brush wheel 40 rotates and presses down the torn edge, so that the fixing needle 32 penetrates into the torn edge. Then, it passes through the blowing member 50, and the nozzle 51 blows air at the torn edge into which the fixing needle 32 is inserted, so that the fixing needle 32 further penetrates deeply into the torn edge, preventing the torn edge from detaching from the fixing needle 32. Finally, the conveying chain 30 drives the knitted fabric into the drying member 20, and the drying member 20 dries and shapes it, ensuring the shaping effect.

[0031] In a possible implementation manner, the above-mentioned frame 10 adopts the structure as shown in Figure 1 and Figure 2 shown, see Figure 1 and Figure 2, two brush idler wheels 42 with main shafts extending in the front-rear direction are rotatably connected to the top of the frame 10. The brush idler wheels 42 are located between the main brush wheel 40 and the drying member 20. The two brush idler wheels 42 are arranged in one-to-one correspondence with the two conveyor chains 30, and are used to rotate and press down the torn edge so that the fixing needles 32 penetrate into the torn edge.

[0032] Specifically, the nozzle 51 is located between the brush idler wheel 42 and the main brush wheel 40, and the brush idler wheel 42 is located above the needle plate 31. When the knitted fabric passes through the main brush wheel 40, the main brush wheel 40 rotates and presses down the torn edge, so that the fixing needles 32 penetrate into the torn edge. Then, it passes through the blowing member 50. The nozzle 51 blows air at the torn edge into which the fixing needles 32 are inserted, so that the fixing needles 32 are further deeply inserted into the torn edge. Then the knitted fabric passes through the brush idler wheel 42, and the brush idler wheel 42 further rotates and presses down the knitted fabric onto the fixing needles 32, ensuring that the torn edge is stably fixed on the fixing needles 32 and ensuring the stability of the torn edge fixation.

[0033] In some embodiments, see Figure 1 and Figure 2 , the main brush wheel 40 is rotatably connected to the frame 10 through the driving shaft 41, the brush idler wheel 42 is rotatably connected to the frame 10 through the driven shaft 43. An active sprocket 44 is fixedly sleeved on the outer periphery of the driving shaft 41, a driven sprocket 45 is fixedly sleeved on the outer periphery of the driven shaft 43, and a synchronous chain 46 is wound around the outer peripheries of the active sprocket 44 and the driven sprocket 45. One end of the driving shaft 41 away from the main brush wheel 40 is connected with a first rotary driving member 47, and the nozzle 51 is located between the main brush wheel 40 and the brush idler wheel 42.

[0034] Specifically, the first rotary driving member 47 drives the driving shaft 41 to rotate, driving the main brush wheel 40 to rotate. Under the transmission of the active sprocket 44, the driven sprocket 45 and the synchronous chain 46, the driven shaft 43 also rotates, so that the main brush wheel 40 and the brush idler wheel 42 rotate synchronously, and successively roll and press down the torn edge, so that the torn edge is stably inserted on the fixing needles 32, improving the practicability.

[0035] Moreover, the setting mode of the active sprocket 44, the driven sprocket 45 and the synchronous chain 46 can reduce the setting of motors. One first rotary driving member 47 can drive the main brush wheel 40 and the brush idler wheel 42 to rotate simultaneously, saving costs.

[0036] In some embodiments, see Figures 1 to 4 , a fixing plate 12 extending upward above the synchronous chain 46 is provided at the top of the frame 10. The upper end of the fixing plate 12 is connected with an extension plate 13 extending inward. The extending end of the extension plate 13 is connected with a mounting plate 14 extending downward. The synchronous chain 46 is located between the mounting plate 14 and the fixing plate 12. The nozzle 51 is fixed to the side of the mounting plate 14 away from the synchronous chain 46 through a locking member 60.

[0037] Specifically, the fixing plate 12, the extension plate 13, and the mounting plate 14 are arranged in a way to avoid the synchronous chain 46 and facilitate the installation of the nozzle 51. That is, the nozzle 51 is connected to the mounting plate 14 through the locking member 60, improving the convenience of use.

[0038] In some embodiments, refer to Figures 1 to 4 , the locking member 60 includes a screw 61 and a locking sleeve 62. The screw 61 is connected to the outer peripheral wall of the nozzle 51 and penetrates the mounting plate 14 along the radial direction of the nozzle 51; one end of the locking sleeve 62 has an axially extending opening. The locking sleeve 62 is threadedly sleeved on the outer periphery of the screw 61 and abuts against the mounting plate 14, and the locking sleeve 62 is located on the side of the mounting plate 14 close to the synchronous chain 46.

[0039] Specifically, a reserved hole is provided on the mounting plate 14. The screw 61 passes through the reserved hole from the side of the mounting plate 14 away from the fixing plate 12. The locking sleeve 62 is threadedly sleeved on the outer periphery of the screw 61 from the side of the mounting plate 14 close to the fixing plate 12, and both the locking sleeve 62 and the nozzle 51 abut against the side wall of the mounting plate 14, thus completing the fixation of the position of the nozzle 51.

[0040] And when it is necessary to adjust the orientation of the nozzle 51, the locking sleeve 62 can be loosened and the nozzle 51 can be rotated for adjustment, improving the convenience of use.

[0041] In some embodiments, refer to Figures 1 to 5 , an elastic pressing member 70 extending along the axial direction of the locking sleeve 62 is provided on the inner bottom wall of the locking sleeve 62. The elastic pressing member 70 can elastically push the screw 61 away from the inner bottom wall of the locking sleeve 62 to screw the screw 61 tightly on the locking sleeve 62.

[0042] Specifically, when the screw 61 approaches the inner bottom wall of the locking sleeve 62, the elastic pressing member 70 gradually presses against the end of the screw 61, making the screw 61 stably connected to the locking sleeve 62, avoiding loosening due to external vibration, and ensuring the stability of the position of the nozzle 51.

[0043] In some embodiments, refer to Figures 1 to 5 , the elastic pressing member 70 includes an elastic member 72 and a gasket 71. The elastic member 72 is connected to the inner bottom wall of the locking sleeve 62 and extends towards the open end of the locking sleeve 62; the gasket 71 is connected to the extending end of the elastic member 72, and the elastic member 72 can elastically push the gasket 71 to abut against the end of the screw 61.

[0044] Specifically, the setting of the gasket 71 can effectively protect the elastic member 72, preventing the screw rod 61 from directly contacting the elastic member 72 during the screwing-in process and damaging the elastic member 72. When the screw rod 61 is screwed into the locking sleeve 62, the end of the screw rod 61 abuts against the gasket 71 and gradually compresses the elastic member 72. Under the urging force of the elastic member 72, the screw rod 61 is stably connected to the locking sleeve 62, thus avoiding loosening due to external vibration.

[0045] Furthermore, the gasket 71 is slidably connected to the inner wall of the locking sleeve 62.

[0046] In some embodiments, referring to Figures 1 to 5 , the mounting plate 14 is provided with a long hole 15 extending in the up and down direction, and the screw rod 61 passes through the long hole 15.

[0047] Specifically, when it is necessary to adjust the height of the nozzle 51, the locking sleeve 62 can be loosened to enable the screw rod 61 to slide up and down along the long hole 15. After the adjustment is completed, the locking sleeve 62 can be tightened, further improving the convenience of adjusting the position of the nozzle 51.

[0048] In a possible implementation manner, the above-mentioned blowing member 50 adopts the structure as shown in Figure 1 and Figure 2 , referring to Figure 1 and Figure 2 , the blowing member 50 includes a blower 52 and a hose 53. The blower 52 is arranged on the top of the frame 10 for supplying gas; one end of the hose 53 is connected to the top of the blower 52 and the other end is connected to the nozzle 51.

[0049] Specifically, the blower 52 is used to supply gas to the nozzle 51 through the hose 53. The hose 53 has a certain deformation ability and can change its position following the nozzle 51, improving the convenience.

[0050] In a possible implementation manner, the above-mentioned conveying cavity 11 adopts the structure as shown in Figure 1 and Figure 2 , referring to Figure 1 and Figure 2 , two rotating shafts 80 are rotatably connected in the conveying cavity 11 and are arranged at intervals in the front and back direction. The rotating shafts 80 extend in the left and right direction. Two sets of transmission sprockets 81 are fixedly sleeved on the outer periphery of the rotating shafts 80. The two sets of transmission sprockets 81 are respectively arranged near the two ends of the rotating shafts 80. Each set of transmission sprockets 81 includes two transmission sprockets 81 respectively fixedly sleeved on the outer periphery of the two rotating shafts 80. The two conveying chains 30 are arranged in one-to-one correspondence with the two sets of transmission sprockets 81. Each conveying chain 30 is wound around the outer periphery of the two transmission sprockets 81 of the corresponding set. One end of one of the rotating shafts 80 is connected to a second rotation driving member 82.

[0051] Specifically, the second rotation driving member 82 drives one of the rotating shafts 80 to rotate, and drives the knitted fabric to be conveyed forward under the synchronous cooperation of the two sets of conveying sprockets 81 and the two conveying chains 30, so as to realize the synchronous advancement of the edge tearing on both sides of the knitted fabric.

[0052] Further, the rotation direction of the conveying sprocket 81 is opposite to that of the corresponding side brush main wheel 40, and the rotation speed of the brush main wheel 40 is adapted to the moving speed of the conveying chain 30, so as to ensure that while the pressing edge tearing is inserted onto the fixing needle 32, it can also cooperate with the conveying chain 30 to provide the power for the synchronous forward movement of the knitted fabric, and avoid damage and wrinkles of the knitted fabric.

[0053] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
