[0027] like Figure 5-6 As shown, this example can achieve the effect of fully calendering the plastic into a film at one time.

[0028] Since the plastic film processing equipment includes a gate-shaped plate 101, the front and rear ends of the gate-shaped plate 101 are vertically slidably connected with multiple vertical bars 104 from left to right, and a roller 106 is rotatably connected between the lower ends of the two front and rear opposite vertical bars 104, and the multiple vertical bars 104 gradually increase in length from left to right, and the multiple rollers 106 are arranged in a stepped shape with the left higher and the right lower, driving the gate-shaped plate 101 to move downward and then to the right. At this time, the first roller 106 at the right end is pressed on the molten plastic, and then the second roller 106 is pressed on the molten plastic and moves to the right, so that the multiple rollers 106 are pressed on the molten plastic and move to the right in turn, and the plastic is calendered multiple times by multiple rollers 106, so that the plastic can be fully calendered into a film at one time.

[0029] like Figure 5-6 As shown, this example can achieve the effect of rolling the plastic into a plastic film by a plurality of rollers 106 .

[0030] Since each of the vertical bars 104 is plugged with a stop pin 102 at the top, each of the vertical bars 104 is welded with a convex plate 105 at the bottom, each of the convex plates 105 is welded with an elastic rod 103 at the top, and each of the elastic rods 103 is welded to the bottom of the door-shaped plate 101, the elastic rod 103 gives the corresponding vertical bar 104 a downward sliding force, so that the multiple vertical bars 104 always have downward elastic force, and then the multiple rollers 106 can press on the plastic through elastic force, and then the plastic is rolled into a plastic film by the multiple rollers 106. The stop pin 102 can prevent the vertical bar 104 from detaching from the door-shaped plate 101.

[0031] like Figure 5-8 As shown, this example can achieve the effect of the electric heating plate 211 heating the flat plate 201 .

[0032] Since a flat plate 201 is arranged below the multiple rollers 106, support rods 210 are welded at the four corners of the lower side of the flat plate 201, and an electric heating plate 211 is arranged on the lower side of the flat plate 201, the four support rods 210 support the flat plate 201, and the flat plate 201 is used to place plastic. The multiple rollers 106 press on the plastic on the flat plate 201 to calender the plastic. The electric heating plate 211 heats the flat plate 201, so that the plastic on the flat plate 201 will not solidify too quickly, which facilitates the calendering of the plastic.

[0033] like Figure 7-8 As shown, this example can achieve the effect of limiting the width of the plastic after calendering.

[0034] Since two front and rear baffles 203 are arranged on the upper side of the flat plate 201, slide bars 206 are welded on the left and right ends of each baffle 203, and fixed seats 205 are welded at the four corners of the flat plate 201. Multiple slide bars 206 are respectively slidably connected to multiple fixed seats 205, and each fixed seat 205 is threadedly connected with a fastening screw 204, which is pressed on the corresponding slide bar 206. The slide bar 206 can slide on the corresponding fixed seat 205, thereby driving the front and rear baffles 203 to move forward and backward relative to the flat plate 201. The position of the baffle 203 can be fixed by rotating the fastening screw 204 to press on the slide bar 206. The spacing between the two baffles 203 is adjusted according to the front and rear width of the plastic film to be processed, the plastic is limited, and the width of the plastic after calendering is restricted.

[0035] like Figure 7-8 As shown, this example can achieve the effect of preventing the solidified plastic film from adhering to the flat plate 201 .

[0036] Since a plurality of strip grooves 202 are provided on the upper side of the flat plate 201 from left to right, a soft strip 208 is provided at each strip groove 202, the front ends and rear ends of the plurality of soft strips 208 are respectively welded to the front and rear side bars 207, and a convex piece 209 is welded to the lower side of each side bar 207. The front and rear ends of the lower side of the flat plate 201 are connected to a telescopic rod 1 212 by screws, and the movable ends of the two telescopic rods 1 212 are respectively connected to the two convex pieces 209 by screws. The two side bars 207 are driven to move forward and backward by the telescopic movement of the two telescopic rods 1 212. When the two side bars 207 are close to each other, the middle parts of the plurality of soft strips 208 are driven to bulge upward, thereby lifting up the solidified plastic film on the flat plate 201 to prevent the solidified plastic film from adhering to the flat plate 201.

[0037] like Figure 1-9 As shown, this example can achieve the effect of calendering a plastic film with wider front and back widths.

[0038] Since the four support rods 210 are all welded to the base 301, a track 302 is provided at the right end of the base 301, a stand 303 is slidably connected to the track 302, a slot rod 305 is welded to the upper part of the stand 303, a lifting seat 309 is vertically slidably connected to the slot rod 305, a cross bar 306 is horizontally slidably connected to the lifting seat 309, the left end of the cross bar 306 is welded to the right end of the door-shaped plate 101, the cross bar 306 can move vertically on the slot rod 305, and the cross bar 306 can move left and right on the lifting seat 309 , so that the cross bar 306 can move up and down, left and right, and so that the door-shaped plate 101 and multiple rollers 106 can move up and down, left and right, and so on, drive the multiple rollers 106 to press on the plastic in sequence; the stand 303 can move forward and backward on the track 302, so that the cross bar 306, the door-shaped plate 101 and multiple rollers 106 can move forward and backward. When the distance between the two baffles 203 becomes larger, the multiple rollers 106 can be driven to press on the plastic multiple times at different front and rear positions, thereby rolling out a plastic film with a wider front and rear width.

[0039] like Figure 1-9 As shown, this example can achieve the effect of driving the door plate 101 to move in multiple directions.

[0040] Since the base 301 is fixed with a telescopic rod three 310, the movable end of the telescopic rod three 310 is fixed on the stand 303, the stand 303 is fixed with a telescopic rod two 304, the movable end of the telescopic rod two 304 is fixed on the lower side of the lifting seat 309, the right end of the cross bar 306 is fixed with a motor 307, the output shaft of the motor 307 is fixed with a screw 308, the screw 308 cooperates with the lifting seat 309 through a thread, the telescopic rod three 310 drives the stand 303 to slide on the track 302, the telescopic rod two 304 drives the lifting seat 309 to slide on the slot rod 305, the motor 307 drives the screw 308 to rotate, and then drives the cross bar 306 to slide on the lifting seat 309, and then drives the door-shaped plate 101 to move in multiple directions.

[0041] like Figure 1-10 As shown, this example can achieve the effect of cutting and trimming the manufactured plastic film.

[0042] Because the rear side of the groove rod 305 is welded with a convex frame 404, a rubber sleeve 402 is arranged on the convex frame 404, a push-pull rod 401 is slidably connected to the rubber sleeve 402, a handle 403 is welded to the right end of the push-pull rod 401, baffles 407 are welded to the front and rear ends of the bar 406, and knives 405 are slidably connected to the front and rear ends of the bar 406, and the two knives 405 are respectively fitted with the inner sides of the two baffles 203, a compression spring is sleeved on the bar 406, and the compression spring is located between the two knives 405. The baffle 407 located at the rear side is welded to the front and rear ends of the bar 406. Connected to the left part of the push-pull rod 401, the compression spring gives elastic force to the two cutting knives 405, so that the two cutting knives 405 are respectively pressed on the inner sides of the two baffle bars 203. When the plastic film is calendered, the push-pull rod 401 is driven by the handle 403 to slide rightward on the rubber sleeve 402. The friction force is increased by the rubber sleeve 402, so that the push-pull rod 401 can be fixed on the protrusion 404 at any time, thereby driving the bar 406 and the two cutting knives 405 to slide rightward, and the two cutting knives 405 pass through the front and rear edges of the plastic film, thereby cutting and trimming the manufactured plastic film.
