[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] Embodiment:

[0033] As Figures 1-4 shown, this embodiment provides a hemming machine for plastic packaging production, including an operating table 1 with multiple support columns arranged at the bottom; a lower heating sheet 2 arranged on the operating table 1 for heating plastic packaging; an L-shaped bracket 3 fixedly installed on the operating table 1 for the installation and support of the mechanism; a hydraulic rod 4 fixedly installed on the L-shaped bracket 3 for hemming plastic packaging; a pressing plate 5 fixedly installed at the output end of the hydraulic rod 4 for hemming plastic packaging; an upper heating sheet 6 arranged at the bottom of the pressing plate 5 for heating plastic packaging; a fixing member 7 movably arranged above the operating table 1 for fixing plastic packaging during hemming; a fan assembly 8 movably arranged above the operating table 1 for cooling plastic packaging after hemming; a fixing member adjusting mechanism 9 arranged on the pressing plate 5 and the fixing member 7 for adjusting the position of the fixing member 7 to fix plastic packaging of different sizes; a fan assembly adjusting mechanism 10 arranged on the operating table 1 and the fan assembly 8 for adjusting the position of the fan assembly 8 to evenly cool the hemming of plastic packaging;

[0034] During use, place the edge of the plastic packaging on the lower heating sheet 2, and then adjust the positions of the two sets of fixing members 7 according to the size of the plastic packaging so that the two sets of fixing members 7 are located above both ends of the plastic packaging. When pressing the edge, the extension of the hydraulic rod 4 will drive the pressing plate 5 to move downward, and the downward movement of the pressing plate 5 will drive the upper heating sheet 6 to move downward. On the other hand, when the pressing plate 5 moves downward, it will drive the fixing member 7 to move downward. The fixing member 7 will first contact the plastic packaging and clamp and fix both ends of the plastic packaging to prevent the plastic packaging from shifting during edge pressing. Then, the pressing plate 5 drives the upper heating sheet 6 to descend to press the edge of the plastic packaging. When pressing the edge, the lower heating sheet 2 and the upper heating sheet 6 generate heat to melt the edge of the plastic packaging, achieving the heat-sealing effect on the plastic packaging. After edge pressing, the pressing plate 5 and the upper heating sheet 6 are lifted by the hydraulic rod 4. At this time, the fixing member 7 still abuts against the plastic packaging. The blower assembly adjustment mechanism 10 can drive the blower assembly 8 to move back and forth to blow air onto the edge-pressed plastic packaging, enabling the edge of the plastic packaging to cool and solidify quickly, and preventing the edge from opening when collecting and processing the plastic packaging.

[0035] In one embodiment, specifically, the fixing member 7 includes a fixing plate 71 and a contact pad 72. The fixing plate 71 is movably arranged above the operating table 1, and the contact pad 72 is fixedly connected to the bottom of the fixing plate 71.

[0036] The downward movement of the fixing plate 71 will drive the contact pad 72 to move downward, and the downward movement of the two contact pads 72 will abut against both ends of the plastic packaging to fix the plastic packaging before edge pressing.

[0037] In one embodiment, specifically, the blower assembly 8 includes a cold air blower 81 and a wind guide plate 82. The cold air blower 81 is slidably arranged above the operating table 1, and the wind guide plate 82 is fixedly connected to the cold air blower 81.

[0038] The air blown out by the cold air blower 81 can be blown onto the edge-pressed plastic packaging under the guiding action of the wind guide plate 82, enabling the edge of the plastic packaging to cool and solidify quickly.

[0039] In one embodiment, specifically, the fixing member adjustment mechanism 9 includes a connecting frame 91, a housing 92, a double-headed lead screw 93, a lead screw sleeve 94, a connecting member 95, and a buffer spring 96. The connecting frame 91 is fixedly connected to the pressing plate 5, the housing 92 is fixedly connected to the connecting frame 91, the double-headed lead screw 93 is rotatably connected to the housing 92, the lead screw sleeve 94 is movably sleeved on the double-headed lead screw 93, the connecting member 95 is fixedly connected to the lead screw sleeve 94, and the two ends of the buffer spring 96 are respectively fixedly connected to the connecting member 95 and the fixing plate 71.

[0040] When it is necessary to adjust the positions of the two sets of fixing members 7, the double-headed lead screw 93 can be rotated. The rotation of the double-headed lead screw 93 can drive the two sets of lead screw sleeves 94 to move towards or away from each other on the double-headed lead screw 93, and can drive the two sets of connecting members 95 and buffer springs 96 to move towards or away from each other, so as to adjust the positions of the two sets of fixing members 7 to adapt to plastic packages of different sizes. Through the setting of the buffer spring 96, when the fixing member 7 abuts against the plastic package, the continued downward movement of the pressing plate 5 and the upper heating sheet 6 will cause the compression of the fixing member 7. When the pressing plate 5 and the upper heating sheet 6 are lifted by a small distance, at this time, the buffer spring 96 is not fully extended, and the two sets of fixing members 7 still abut against the plastic package. At this time, the blower assembly 8 is used to cool and cure the edge, and the plastic package will not move.

[0041] In one embodiment, specifically, the fixing member adjusting mechanism 9 further includes a telescopic rod 97 and a knob 98. The two ends of the telescopic rod 97 are respectively fixedly connected to the fixing plate 71 and the connecting member 95, and the knob 98 is fixedly connected to the end of the double-headed lead screw 93.

[0042] Through the setting of the telescopic rod 97, the fixing member 7 can be lifted and lowered stably without causing the fixing member 7 to be skewed. Through the setting of the knob 98, the rotation of the double-headed lead screw 93 can be facilitated.

[0043] In one embodiment, specifically, the fixing member adjusting mechanism 9 further includes a support ring 99 and a limit ring 910. The support ring 99 is fixedly connected to the end of the housing 92, and the limit ring 910 is rotatably sleeved in the support ring 99;

[0044] Through the setting of the support ring 99, support can be provided for the double-headed lead screw 93. Through the setting of the limit ring 910, the double-headed lead screw 93 can be limited to prevent the double-headed lead screw 93 from moving in the housing 92.

[0045] In one embodiment, specifically, the blower assembly adjusting mechanism 10 includes a support plate 101, a rotating rod 102, a movable sleeve 103, a guide sleeve 104 and a guide rod 105. The support plate 101 is fixedly connected to the operating table 1, the rotating rod 102 is rotatably connected to the support plate 101, the movable sleeve 103 is movably sleeved on the rotating rod 102, the guide sleeve 104 is fixedly connected to the movable sleeve 103, and the guide rod 105 is fixedly connected to the support plate 101. The guide sleeve 104 is slidably sleeved on the guide rod 105;

[0046] When it is necessary to adjust the position of the blower assembly 8 to evenly cool the edge, through the guiding action of the guide sleeve 104 and the guide rod 105, the rotation of the rotating rod 102 will drive the movable sleeve 103 to move back and forth on the rotating rod 102. The back-and-forth movement of the movable sleeve 103 can drive the blower assembly 8 to move back and forth to evenly cool the edge.

[0047] In one embodiment, specifically, the fan assembly adjusting mechanism 10 further includes a slider 106, an oval groove 107, and a driving motor 108. The slider 106 is fixedly connected to the movable sleeve 103. The oval groove 107 is formed in the rotating rod 102, and the slider 106 is slidably installed in the oval groove 107.

[0048] When the rotating rod 102 rotates, it will drive the slider 106 to move back and forth in the oval groove 107. The back-and-forth movement of the slider 106 can drive the movable sleeve 103 to move back and forth. Through the setting of the driving motor 108, the rotation of the driving motor 108 can drive the rotating rod 102 to rotate, providing a power source for the movement of the fan assembly 8.

[0049] Working principle: During use, place the edge of the plastic packaging on the lower heating sheet 2, and then adjust the positions of the two fixing members 7 according to the size of the plastic packaging so that the two fixing members 7 are located above both ends of the plastic packaging. Rotate the double-headed lead screw 93. The rotation can drive the two lead screw sleeves 94 to move towards or away from each other on the double-headed lead screw 93, driving the two connecting members 95 and the buffer springs 96 to move towards or away from each other, thereby adjusting the positions of the two fixing members 7 to adapt to plastic packaging of different sizes. The hydraulic rod 4 extends to drive the pressing plate 5 to move downward. The downward movement of the pressing plate 5 drives the upper heating sheet 6 to move downward. On the other hand, when the pressing plate 5 moves downward, it drives the fixing member 7 to move downward. The downward movement of the fixing plate 71 drives the contact pad 72 to move downward. The downward movement of the two contact pads 72 abuts against both ends of the plastic packaging to fix the plastic packaging before edge pressing. Then, the pressing plate 5 drives the upper heating sheet 6 to descend to press the edge of the plastic packaging. When pressing the edge, the lower heating sheet 2 and the upper heating sheet 6 generate heat to melt the edge of the plastic packaging, achieving the heat sealing effect on the plastic packaging. After edge pressing, the pressing plate 5 and the upper heating sheet 6 are lifted by the hydraulic rod 4. When the fixing member 7 abuts against the plastic packaging, the continuous downward movement of the pressing plate 5 and the upper heating sheet 6 will cause the compression of the fixing member 7. When the pressing plate 5 and the upper heating sheet 6 are lifted a small distance, at this time, the buffer spring 96 is not fully extended, and the two fixing members 7 still abut against the plastic packaging. At this time, the fan assembly 8 cools and cures the edge pressing, preventing the movement of the plastic packaging. The driving motor 108 rotates to drive the rotating rod 102 to rotate. Through the guiding action of the guiding sleeve 104 and the guiding rod 105, the rotation of the rotating rod 102 drives the movable sleeve 103 to move back and forth on the rotating rod 102. The back-and-forth movement of the movable sleeve 103 drives the fan assembly 8 to move back and forth to evenly cool the edge pressing, enabling the edge of the plastic packaging to quickly cool and solidify, and preventing the edge from opening when collecting and processing the plastic packaging.

[0050] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
