[0024] like Figure 4-5 As shown, this example can achieve the effect of firmly connecting two pieces of plastic through the funnel-shaped plastic.
[0025] Since the plastic connection and molding device includes a funnel-shaped frame I101 and a trapezoidal cutter 103, the left and right ends of the lower side of the funnel-shaped frame I101 are welded with trapezoidal cutters 103, and the lower side of the trapezoidal cutter 103 is blade-shaped, after the two plastics to be connected are butt-jointed together, the two trapezoidal cutters 103 on the funnel-shaped frame I101 are used to cut the two pieces of plastic respectively, and a trapezoidal groove is cut on each of the two pieces of plastic, and then a funnel-shaped plastic with the same shape as the funnel-shaped frame I101 is used to be inserted into the two trapezoidal grooves, at this time, the funnel-shaped plastic connects the two pieces of plastic, and then the gap between the funnel-shaped plastic and the two pieces of plastic is hot-melted, so that the funnel-shaped plastic is connected to the two pieces of plastic, and then the two pieces of plastic can be firmly connected through the funnel-shaped plastic.
[0026] like Figure 4-5 As shown, this example can make cutting plastic easier.
[0027] Since the plastic connection and molding device also includes electric heating strips 102, the lower side of the funnel-shaped frame 1101 is connected to the electric heating strips 102 by screws, and the plurality of electric heating strips 102 are all fitted with the upper part of the trapezoidal cutter 103, and then the trapezoidal cutter 103 is heated by the plurality of electric heating strips 102 around, so that the trapezoidal cutter 103 cuts toward the plastic after heating, making it easier to cut the plastic.
[0028] like Figure 4-5 As shown, this example can achieve the effect that the funnel-shaped plastic provides a more stable connection between the two pieces of plastic.
[0029] Since the plastic connection molding device also includes a protrusion 104, each trapezoidal cutter 103 is integrally formed with a protrusion 104 on both the front and rear sides, so that the trapezoidal cutter 103 also cuts two convex grooves on the two pieces of plastic, and then four protrusions corresponding to the convex grooves are provided on the funnel-shaped plastic, and the protrusions on the two funnel-shaped plastics are inserted into the corresponding convex grooves, thereby preventing the funnel-shaped plastic from loosening in the trapezoidal groove, so that the funnel-shaped plastic provides a more stable connection for the two pieces of plastic.
[0030] like Figure 6-7 As shown, this example can achieve the effect of ejecting the plastic remaining in the trapezoidal cutter 103.
[0031] Since the plastic connection and molding device also includes a top beam 201, a cylinder 202 and a connecting beam 203, the upper side of the funnel-shaped frame I101 is connected to the top beam 201 by screws, and the two cylinders 202 are inserted into the top beam 201 with a clearance fit. The two cylinders 202 can slide vertically on the top beam 201, and the connecting beam 203 is arranged on the upper part of the two cylinders 202. When the two trapezoidal cutters 103 cut toward the plastic, the cut plastic sometimes remains in the trapezoidal cutter 103, and then the two cylinders 202 are driven to move downward by the connecting beam 203, thereby ejecting the remaining plastic in the trapezoidal cutter 103.
[0032] like Figure 6-7 As shown, this example can facilitate the downward movement of the two discs 205 to press out the plastic remaining in the trapezoidal cutter 103 .
[0033] Since the plastic connection and molding device also includes a disc 205, the lower ends of the two cylinders 202 are connected to the disc 205 by screws, and two compression springs are respectively sleeved on the two cylinders 202. The compression springs are located on the lower side of the top beam 201. The two compression springs apply downward force to the two cylinders 202 and the two discs 205, so that the two discs 205 always have a tendency to be pressed downward, which facilitates the two discs 205 to move downward to press out the residual plastic in the trapezoidal cutter 103.
[0034] like Figure 6-7 As shown, this example can facilitate the four pressing rods 204 to move downward to press out the plastic remaining in the four protrusions 104.
[0035] Since the plastic connection molding device also includes a pressure rod 204, the front and rear ends of the lower side of the disc 205 are welded with a pressure rod 204, and the four pressure rods 204 are respectively arranged on the inner sides of the four protrusions 104, so that the four pressure rods 204 will always have a downward pressing tendency along with the two discs 205, so that the four pressure rods 204 can move downward to press out the residual plastic in the four protrusions 104.
[0036] like Figure 8-9 As shown, this example can achieve the effect of cutting trapezoidal grooves in two pieces of plastic.
[0037] Since the plastic connection molding device also includes a fixing seat 106, an L-shaped plate 107, a flat plate 301 and a square hole 302, the square hole 302 is arranged on the flat plate 301, and the front and rear ends of the lower side of the flat plate 301 are screwed with the fixing seat 106, the upper parts of the two L-shaped plates 107 are respectively welded to the front and rear sides of the funnel-shaped frame I101, and the two L-shaped plates 107 are respectively inserted into the two fixing seats 106 with vertical clearance fit, and the trapezoidal cutter 103 is arranged above the cylinder 202, and then the two pieces of plastic are placed on the flat plate 301 left and right, and then the cutting position of the two pieces of plastic is placed at the square hole 302, and then the two L-shaped plates 107 slide downward to drive the funnel-shaped frame I101 and the trapezoidal cutter 103 to slide downward, and then trapezoidal grooves are cut on the two pieces of plastic.
[0038] like Figure 4 As shown, this example can achieve the effect of driving the funnel-shaped frame I101 and the trapezoidal cutter 103 to slide vertically.
[0039] Since the plastic connection molding device also includes a hydraulic cylinder I105, each fixed seat 106 is connected to a hydraulic cylinder I105 by screws, and the lower parts of the two hydraulic cylinders I105 are respectively connected to the lower parts of the two L-shaped plates 107 by flanges. When the hydraulic cylinder I105 is extended or retracted, it drives the two L-shaped plates 107 to slide vertically, thereby driving the funnel-shaped frame I101 and the trapezoidal cutter 103 to slide vertically.
[0040] like Figure 8-9 As shown, this example can achieve the effect of preventing the two pieces of plastic from being greatly deformed when the two trapezoidal cutters 103 move downward for cutting.
[0041] Since the plastic connection and molding device also includes pad rods 303, pad rods 303 are welded at the four corners of the square hole 302, and the four pad rods 303 are respectively located on the front and rear sides of the two trapezoidal cutters 103, so that the four pad rods 303 are arranged around the two trapezoidal cutters 103, so that the four pad rods 303 are padded on the lower side of the two pieces of plastic, thereby preventing the two pieces of plastic from being greatly deformed when the two trapezoidal cutters 103 move downward for cutting.
[0042] like Figure 8-9 As shown, this example can achieve the effect of supporting the flat plate 301.
[0043] Since the plastic connection molding device further includes legs 304 , the left and right ends of the lower side of the flat plate 301 are both connected with the legs 304 via screws, and the two legs 304 play a role in supporting the flat plate 301 .
[0044] The plastic connection and molding device also includes a hydraulic cylinder II305, a right-angle column 306, a stop pin 307, a stop head 308 and an angle iron 309. The two right-angle columns 306 are respectively inserted into the two supporting legs 304 with a clearance fit. Each supporting leg 304 is connected to a hydraulic cylinder II305 by screws. The movable ends of the two hydraulic cylinders II305 are respectively fixed to the inner ends of the two right-angle columns 306 by flanges. The two angle irons 309 are respectively inserted into the upper parts of the two right-angle columns 306 with a vertical clearance fit. The two right-angle columns 306 are both threadedly connected with a stop pin 307. The two stop pins 307 are respectively located at the lower sides of the two angle irons 309. The upper parts of the two right-angle columns 306 are both screwed with a stop head 308. The two angle irons 309 are respectively located on the left and right sides of the flat plate 301. The two right-angle columns 306 are both sleeved with a downward pressure spring, which is located between the corresponding stop head 308 and the angle iron 309.
[0045] like Figure 8-9 As shown, this example can achieve the effect of facilitating the two trapezoidal cutters 103 to cut two pieces of plastic.
[0046] The downward pressure spring on the right-angle column 306 exerts downward force on the angle iron 309, so that the two angle irons 309 are pressed on the outside of the two plastics to prevent the two plastics from lifting. Then the two hydraulic cylinders II305 drive the two right-angle columns 306 to move closer to each other, so that the two angle irons 309 move closer to each other, and then the two angle irons 309 press the two plastics to move closer to each other, so that the two trapezoidal cutters 103 can cut the two plastics. The two stop pins 307 play a role of limiting, preventing the two angle irons 309 from moving too downward.
[0047] The plastic connection molding device also includes a funnel-shaped frame II401, a hand rod 402, a rubber strip 403, a folding frame 404 and a protrusion 405. The folding frame 404 is connected to the front of the flat plate 301 by screws. The upper side of the funnel-shaped frame II401 is connected to the hand rod 402 by screws. The front side of the hand rod 402 is bonded with a rubber strip 403. The hand rod 402 is vertically inserted into the upper part of the folding frame 404. A plurality of protrusions 405 are evenly distributed on the lower side of the funnel-shaped frame II401. The funnel-shaped frame II401 is provided with a heating wire.
[0048] like Figure 10-11 As shown, this example can achieve the effect of completely connecting the funnel-shaped plastic with the two pieces of plastic.
[0049] After the two pieces of plastic are connected through the funnel-shaped plastic, the connection position of the two pieces of plastic is placed below the funnel-shaped frame II401, and then the electric heating wire on the funnel-shaped frame II401 heats the funnel-shaped frame II401, and then heats the multiple protrusions 405, so that the multiple protrusions 405 are pressed toward the connection gap between the funnel-shaped plastic and the two pieces of plastic, and the connection gap between the two pieces of plastic is melted through the multiple protrusions 405, and then the funnel-shaped plastic and the two pieces of plastic are completely connected together.
