Description

Technical Field

[0001] The utility model relates to a production device for biaxially oriented nylon film, and more specifically to a take-up device for biaxially oriented nylon film. Background Art

[0002] After the biaxially oriented nylon film is drawn into a film by a transverse drawing machine and a longitudinal drawing machine, it needs to be cooled and wound. During cooling, the film passes through a cooling device, and the air pipe of the cooling device blows air to cool the film, and then it is transported to a winding machine for winding. The film may run off course during the transportation process itself, and because the air pipe blows air to the film, the film is more likely to run off course. Therefore, it is necessary to correct the deviation of the film. However, at present, manual deviation correction is often used, which is time-consuming and laborious. Summary of the Utility Model

[0003] In view of the defects of the above-mentioned prior art, the purpose of the utility model is to provide a take-up device for biaxially oriented nylon film.

[0004] The technical solution of the utility model is: a take-up device for biaxially oriented nylon film, which includes a cooling machine and a winding machine distributed front and back.

Detailed implementation mode

[0015] To understand the technical solution of the present invention more intuitively and completely, the non-limiting feature description is as follows in combination with the drawings of the present invention:

[0016] As Figure 1 — Figure 3 shown, a winding device for biaxially stretched nylon film includes a cooler 100 and a winder 200 distributed front and back. The cooler 100 includes a cooling rack 1. A conveyor line 2 extending front and back is installed at the upper end of the cooling rack 1.

A cooling pipe 5 is installed at the right end of the cooling rack 1. An air pipe 6 located above the conveyor line 2 is connected to the upper end of the cooling pipe 5. The winder 200 includes a winding rack 7. A conveying rack 8 extending front and back is installed at the top of the winding rack 7. A winding drum 9 is installed at the upper rear end of the winder 200. A deviation rectifying device 10 located behind the conveying rack 8 is installed at the upper end of the winding rack 7. The winding drum 9 is located behind the deviation rectifying device 10. The deviation rectifying device 10 includes a motor 101, a transmission mechanism 103 connected to the output shaft of the motor 101, a steering mechanism connected to the transmission mechanism 103, and a plurality of guide wheels 102 connected to the steering mechanism and capable of rotating left and right.

[0017] A guide roller assembly 11 and a third guide wheel shaft assembly 12 are installed at the upper front end of the winder 200 in a vertical distribution. The nylon film is conveyed to the conveying rack 8 after passing around the first guide wheel shaft assembly 3, the second guide wheel shaft assembly 4, the third guide wheel shaft assembly 12, and the guide roller assembly 11. The nylon film is conveyed backward along the conveying rack 8. The nylon film is wound around the winding drum 9 after passing through the guide wheels 102 of the deviation rectifying device 10.

[0018] The motor 101 is fixed inside the upper end of the winding frame 7. The transmission mechanism 103 includes a driving wheel 1031, a driven wheel 1032, and a belt 1033 for connecting the driving wheel 1031 and the driven wheel 1032. The output shaft of the motor 101 is connected to the driving wheel 1031, and the driven wheel 1032 is connected to the steering mechanism, such as Figure 2 shown.

[0019] As Figure 2 shown, the steering mechanism includes a support frame 104 fixed inside the upper end of the winding frame 7, a transmission shaft 105 extending vertically through the support frame 104, and a rotating frame 106 fixedly connected to the upper end of the transmission shaft 105. The lower end of the transmission shaft 105 is fixed to the driven wheel 1032, and the rotating frame 106 passes through the top of the winding frame 7.

[0020] As Figure 2 shown, the steering mechanism further includes a fixing plate 107, a rack 108, and a plurality of gears 109. A plurality of upright columns 1041 extending vertically are fixed to the upper end of the support frame 104. The tops of the upright columns 1041 are fixed to the bottom of the fixing plate 107. Each guide wheel 102 includes a wheel frame 1021 and a wheel 1022 movably connected to the wheel frame 1021. The wheel 1022 is movably connected to the wheel frame 1021 by a pin (not shown in the figure). The lower end of each wheel frame 1021 has a vertically extending axle 10211. A gear 109 is fixedly connected to the outside of each axle 10211. The rack 108 extends left and right, and each gear 109 meshes with the rack 108. The upper end of the rotating frame 106 has a connecting head 1061. The axle 10211 of one of the guide wheels 102 passes through the fixing plate 107 and is fixedly connected to the upper end of the connecting head 1061. The axles 10211 of the remaining guide wheels 102 are movably connected to the fixing plate 107 by vertically extending limit screws 10A. Through holes (not shown in the figure) that penetrate vertically and allow the limit screws 10A to pass through are provided on the fixing plate 107. The lower ends of the limit screws 10A rest against the bottom of the fixing plate 107. The limit screws 10A do not need to be tightened very tightly and need to have a little looseness to allow the axles 10211 to rotate.

[0021] As Figure 3 shown, in order to facilitate the left - right movement of the rack 108, a left - right extending track 10B is fixed at the rear position of the top of the fixing plate 107. The rack 108 is in left - right sliding fit with the track 10B.

[0022] When the motor 101 is working, the output shaft of the motor 101 drives the driving wheel 1031 to rotate. The driving wheel 1031 drives the driven wheel 1032 to rotate through the belt 1033. The driven wheel 1032 drives the transmission shaft 105 to rotate. The transmission shaft 105 drives the rotating frame 106 to rotate. The rotating frame 106 drives the wheel frame 1021 of one of the guide wheels 102 to rotate. The gear 109 connected to the wheel frame 1021 rotates. The gear 109 drives the rack 108 to move. The rack 108 drives the remaining gears 109 to rotate, causing the remaining guide wheels 102 to rotate. When the motor 101 rotates forward and backward, it is used to control the left and right rotation of the guide wheels 102. For example, when the nylon film moves to the left, the guide wheel 102 can be rotated to the right at this time to adjust the direction of the nylon film, thereby playing a role in correcting the deviation. Whether the nylon film is deviated can be observed manually or an inductor can be used to sense the edge of the nylon film, and it can be selected according to actual needs.

[0023] For the material collecting device of the biaxially stretched nylon film provided by the present invention, the guide wheel 102 of the deviation correction device 10 can rotate left and right. When the nylon film deviates during transportation, the nylon film can be corrected by rotating the guide wheel 102 so that the nylon film is transported along the normal route.

[0024] Certainly, the above are only the preferred embodiments of the present invention. Therefore, the patent scope of the present invention is not limited thereby. Any simple modification and equivalent structural changes made by using the content of the specification and drawings of the present invention should be equally included in the patent protection scope of the present invention.
