[0026] like Figure 9-10 As shown, this example can achieve the effect of adjusting the size of the packaging bag as needed.
[0027] Since the packaging bag includes a plastic cloth tube 401, a second hot indentation 408 is provided at the lower edge of the plastic cloth tube 401, a plastic strip 404 is provided at the right end of the plastic cloth tube 401, and the plastic cloth tube 401 is hot pressed on the plastic strip 404 through a plurality of hot pressing points 407. The bottom of the plastic cloth tube 401 is sealed by the second hot indentation 408 to form a plastic packaging bag, and the plastic strip 404 is fixed to the left end of the plastic cloth tube 401 by a plurality of hot pressing points 407. The plastic cloth tube 401 can be rolled up from one end by different numbers of turns using the plastic strip 404 as an inner core, thereby reducing the size of the packaging bag and adjusting the size of the packaging bag as needed.
[0028] like Figure 9-10 As shown, this example can achieve the effect of making it easy to lift the packaging bag.
[0029] Since a plurality of circular holes 402 are provided on the upper portion of the plastic cloth tube 401 from left to right, the packaging bag can be conveniently lifted through the plurality of circular holes 402 .
[0030] like Figure 9-10 As shown, this example can achieve the effect of separating the storage portion of the packaging bag from the plastic strip 404 .
[0031] Since a heat indentation 403 is provided at the right end of the plastic cloth tube 401, and the heat indentation 403 is located on the left side of the plastic strip 404, a plug hole 405 is provided at the end of the plastic strip 404, the plastic strip 404 can be isolated by the heat indentation 403, so that the storage part of the packaging bag is separated from the plastic strip 404.
[0032] like Figure 9-10 As shown, this example can achieve the effect of preventing the rolled-up portion of the plastic cloth tube 401 from being separated from the plastic strip 404 .
[0033] Since the plastic strip 404 is inserted with a clip 406 , the plastic cloth tube 401 is rolled up from one end by different numbers of turns using the plastic strip 404 as an inner core, and then inserted into the plastic strip 404 by the clip 406 , thereby preventing the rolled-up portion of the plastic cloth tube 401 from detaching from the plastic strip 404 .
[0034] like Figure 7-8 As shown, this example can facilitate further processing of the plastic cloth tube 401.
[0035] Since two pillars 202 are welded to the rear part of the base 301, a cross seat 201 is welded to the upper ends of the two pillars 202, and sliding columns 203 are slidably connected to the left and right ends of the cross seat 201. The sliding columns 203 are driven to slide by a hydraulic cylinder, and round rods 206 are welded to the outer ends of the two sliding columns 203. The two sliding columns 203 can slide on the cross seat 201, thereby adjusting the distance between the two round rods 206, and then supporting the plastic cloth tube 401 through the two round rods 206, so as to facilitate further processing of the plastic cloth tube 401.
[0036] like Figure 7-8 As shown, this example can achieve the effect of supporting the plastic strip 404 at the right end of the plastic cloth tube 401 .
[0037] Since the rear part of the base 301 is provided with a track 302, a slide 303 is slidably connected to the track 302, a fastening screw is threadedly connected to the slide 303, a hydraulic cylinder is fixed on the upper side of the slide 303, a plug 304 is fixed on the upper part of the hydraulic cylinder, and a limit block 305 is provided at the lower part of the plug 304. The plug 304 can be driven to rise and fall by the extension and contraction of the hydraulic cylinder, and then the plug 304 is inserted into the jack 405 on the plastic strip 404, and then the plastic strip 404 is supported on the right end of the plastic cloth tube 401. The limit block 305 prevents the plastic strip 404 from sliding off the plug 304. The slide 303 can slide left and right on the track 302, and then adjust the left and right position of the plug 304, and then adjust the left and right position of the plastic strip 404.
[0038] like Figure 7-8 As shown, this example can achieve the effect of processing a plurality of circular holes 402 on the plastic cloth tube 401.
[0039] Since a cylinder seat 205 is slidably connected to the two pillars 202, a plurality of cylinders 204 are fixed on the cylinder seat 205 from left to right, and an electric heating wire is arranged on the cylinder seat 205, the plurality of cylinders 204 are driven to rise and fall by the lifting and lowering of the cylinder seat 205, the electric heating wire heats the plurality of cylinders 204, and then a plurality of circular holes 402 are processed on the plastic cloth cylinder 401 through the plurality of cylinders 204.
[0040] like Figure 5-8 As shown, this example can achieve the effects of hot pressing a hot pressing mark 1 403 , a hot pressing mark 2 408 and multiple hot pressing points 407 .
[0041] Since the front part of the base 301 is fixed with a vertical column 101, the upper part of the vertical column 101 is fixed with a motor 102, the output shaft of the motor 102 is fixed with a screw 103, the upper and lower parts of the screw 103 have opposite screw threads, the left parts of the two clamping strips 104 are vertically slidably connected to the vertical column 101, the upper and lower parts of the screw 103 are respectively matched with the two clamping strips 104 through threads, the opposite surfaces of the two clamping strips 104 are fixed with convex ridges 105, the two clamping strips 104 are provided with electric heating wires, and the left parts of the two clamping strips 104 are fixed with clamping rods 107 The lower side of the two clamping rods 107 is provided with a convex ridge 108, and the two clamping rods 107 are provided with electric heating wires. Each clamping rod 107 is provided with multiple round needles 106 from front to back. The motor 102 drives the screw rod 103 to rotate, thereby driving the two clamping strips 104 to move closer to or away from each other on the vertical column 101, thereby driving the two clamping rods 107 to move closer to or away from each other, thereby hot pressing a hot indentation 408 on the plastic cloth tube 401 through the two convex ridges 105, and hot pressing a hot indentation 403 on the plastic cloth tube 401 through the two convex ridges 108. The multiple round needles 106 press against the plastic cloth tube 401 and the plastic strip 404, thereby pressing out multiple hot pressing points 407 to connect the plastic cloth tube 401 and the plastic strip 404.
