Description

Technical Field

[0001] This utility model relates to the technical field of cast film production equipment, and in particular to a static voltage edge device for PET cast film processing. Background Technology

[0002] Electrostatic voltage edge technology is a technique that uses the principle of electrostatic adsorption to charge the surface of an object with a high voltage, thereby achieving precise locking and positioning of the material. This technology has wide applications in many industries, especially in the field of cast film processing. In the process of casting extruded molten plastic film, it is necessary to attach the extruded molten plastic film to the surface of the casting roller for casting. The electrostatic voltage edge device is an auxiliary device used to attach the extruded molten plastic film to the surface of the casting roller. Its working principle is that when a DC voltage is applied to the electrode of the electrostatic voltage edge device, the air around the electrode generates a corona discharge under the action of high voltage, which ionizes the air and generates positive and negative ions. The positive ions flow to the surface of the casting roller, thereby enabling the extruded molten plastic film to adhere tightly to the surface of the casting roller. Although the existing electrostatic voltage edge device can make the extruded molten plastic film adhere tightly to the surface of the casting roller, improving the efficiency and quality of casting film formation, the flatness and levelness of the electrode lines of the existing electrostatic voltage edge device cannot be guaranteed. In the production of cast film, it is impossible to guarantee the uniformity of the distribution of positive ions in the direction of the casting roller, resulting in a reduction of positive ions received by the casting roller and affecting the edge pressing effect. Utility Model Content

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] like Figures 1 to 5 As shown, this embodiment provides an electrostatic voltage edge device for PET cast film processing, including an electrostatic generator, a mounting frame 103, and an adjustment mechanism. The mounting frame 103 is provided with two parallel X-axis tracks 204. The adjustment mechanism 2 is slidably mounted on the X-axis tracks 204 via the mounting plate 104. The electrostatic generator is mounted on the adjustment mechanism 2. The electrostatic generator includes a discharge host 101 and an electrode wire 102 connected to the output end of the discharge host 101. The electrode wire 102 is horizontally arranged. The other end of the electrode wire 102 is mounted on the mounting plate 104 via a tension adjustment mechanism 3. The tension adjustment mechanism 3 includes a column 301 fixed on the mounting plate 104, a position adjustment mechanism provided on the column 301, a take-up wheel 302 rotatably mounted on the position adjustment mechanism, and a positioning mechanism cooperating with the take-up wheel 302. The positioning mechanism includes a ratchet 303 coaxially mounted on the take-up wheel 302 and a pawl 304 provided on the position adjustment mechanism. The pawl 304 cooperates with the ratchet 303.

[0020] The position adjustment mechanism includes a first plate 305 and a second plate 306. The first plate 305 is vertically mounted on the column 301 and has a vertically extending first strip-shaped hole. A first locking screw 307 passes through the first strip-shaped hole, and the first plate 305 is mounted on the column 301 by the first locking screw 307. The second plate 306 is horizontally mounted on the first plate 305 and has a horizontally extending second strip-shaped hole. A second locking screw 308 passes through the second strip-shaped hole, and the second plate 306 is mounted on the first plate 305 by the second locking screw 308. The winding wheel 302 is rotatably mounted on the second plate 305. At the end of 06, a ratchet 303 is provided on one side of the take-up reel 302, and a pawl 304 that cooperates with the ratchet 303 is provided on the second plate 306. In this embodiment, the pawl 304 is rotatably mounted above the ratchet 303. The take-up reel 302 can rotate in one direction to tighten the electrode wire 102. By moving the pawl 304 to separate it from the ratchet 303, the take-up reel 302 can rotate freely. When adjusting the position of the electrode wire 102, the first locking screw 307 can be loosened to adjust the position of the first plate 305 in the vertical direction, and the second locking screw 308 can be loosened to adjust the position of the second plate 306 in the horizontal direction. In this way, the positions of the take-up reel 302 and the electrode wire 102 can be adjusted.

[0021] In this embodiment, the adjustment mechanism 2 is provided on the base plate 2011 on the mounting plate 104, the X-axis adjustment mechanism 201 is provided on the base plate 2011, the Y-axis adjustment mechanism 202 is provided on the X-axis adjustment mechanism 201, and the tilt adjustment mechanism 203 is provided on the Y-axis adjustment mechanism 202. The discharge host 101 is mounted on the tilt adjustment mechanism 203.

[0022] In this embodiment, the X-axis adjustment mechanism 201 includes an X-axis moving plate 2012 and an X-axis adjusting screw assembly. The X-axis moving plate 2012 is movably mounted on the base plate 2011 via the X-axis adjusting screw assembly. The X-axis adjusting screw assembly includes an X-axis screw 2013 rotatably mounted on the base plate 2011 and an X-axis nut 2014 disposed on the X-axis screw 2013. The X-axis nut 2014 is connected to the X-axis moving plate 2012. The base plate 2011 is provided with a dovetail groove, and a dovetail tenon is provided on the base plate 2011 to mate with the dovetail groove. A handwheel is provided at one end of the X-axis lead screw 2013. Rotating the handwheel allows adjustment of the position of the discharge host 101 in the X-axis direction and simultaneously adjusts the tension of the electrode wire 102. The Y-axis adjustment mechanism 202 includes a Y-axis base plate 2021, a Y-axis moving plate 2022, and a Y-axis adjusting lead screw pair fixed to the X-axis moving plate 2012. The Y-axis moving plate 2022 is connected to the Y-axis adjusting lead screw... The rod pair is movably mounted on the Y-axis base plate 2021. The tilt adjustment mechanism 203 includes a fixed inclined plate 2031, a movable inclined plate 2032, and a tilt adjustment screw pair, all of which are tilted and mounted on the Y-axis movable plate 2022. The movable inclined plate 2032 is movably mounted on the fixed inclined plate 2031 via the tilt adjustment screw pair. In this embodiment, the Y-axis adjustment mechanism 202 and the tilt adjustment mechanism 203 adopt the same dovetail groove and dovetail tenon sliding structure as the X-axis adjustment mechanism 201. The specific structure will not be described in detail here. The discharge host 101 is mounted on the movable inclined plate 2032. One end of the electrode line 102 is connected to the electrode of the discharge host 101. When adjusting the position of the electrode line 102, the X-axis adjustment mechanism 201 adjusts the position of the discharge host 101 in the X-axis direction, the Y-axis adjustment mechanism 202 adjusts the position of the discharge host 101 and the electrode line 102 in the Y-axis direction, and the tilt adjustment mechanism 203 adjusts the position of the discharge host 101 and the electrode line 102 in the tilt direction.

[0023] The electrostatic pressing device for PET cast film processing in this embodiment can ensure the flatness and levelness of the electrode line 102 by adjusting the electrode line 102, so that the casting roller can receive enough positive ions to ensure the pressing effect. When the pressing device for PET cast film processing in this embodiment is in operation, the position of the electrode line 102 is first adjusted by the position adjustment mechanism so that the end of the electrode line 102 close to the column 301 is kept at a set distance from the casting roller. Then, the position and levelness of the electrode line 102 are adjusted by the adjustment mechanism 2 so that the electrode line 102 is kept horizontal with the casting roller.
