1. A laminator, comprising:
a main body (110), wherein the main body (110) is provided with a feeding port (101), a discharging port (102), and a lamination space (103) arranged between the feeding port (101) and the discharging port (102);
a guide roller (120), wherein the guide roller (120) is arranged on one side, adjacent to the feeding port (101), in the main body (110);
a heating assembly (130), wherein the heating assembly (130) is arranged in the lamination space (103), and the heating assembly (130) is configured to heat a lamination film and a piece to be laminated;
a lamination roller (140), wherein the lamination roller (140) is arranged in the lamination space (103) and configured to roll and fix the lamination film; a preheating space (104) is further arranged between the guide roller (120) and the lamination roller (140); the preheating space (104) is communicated to the lamination space (103); the preheating space (104) is configured to allow the lamination film and the piece to be laminated to pass through; and a distance h between the guide roller (120) and the lamination roller (140) is greater than a preset distance H, and the preset distance H is 4 cm;
a temperature detection device (160) and a control device (170),
wherein the main body (110) comprises an upper mounting member (111), a lower mounting member (112), a first thermal conductive plate (113) and a second thermal conductive plate (113); the first thermal conductive plate (113) extends along a surface of the upper mounting member (111) towards the guide roller (120), the second conductive plate (113) extends along a surface of the lower mounting member (112) towards the guide roller (120); the preheating space (104) is formed between the first and the second thermal conductive plates (113), two ends of the two thermal conductive plate (113) are adjacent to the guide roller (120) and the lamination roller (140) respectively, the heating assembly (130) is located between the upper mounting member (111) and the lower mounting member (112), the first thermal conductive plate (113) and the upper mounting member (111) are integrative structure and the second thermal conductive plate (113) and the lower mounting member (112) are integrative structure, such that heat from the heating assembly (130) is able to be transferred to the preheating space (104) via the second thermal conductive plate (113), the lower mounting member (112), the first and the second conductive plates (113);
wherein the heating assembly (130), the preheating space (104), the temperature detection device (160) and the control device (170) are configured in a manner that when the lamination film and the piece to be laminated are placed into the feeding port (101), the heating assembly (130) works, temperatures of the lamination roller (140), the lamination space (103), and the preheating space (104) gradually increase, the guide roller (120) rotates to guide the piece to be laminated and the lamination film to the lamination roller (140) along the preheating space (104) by traveling through the distance h, at this time the lamination space (103) and the lamination roller (140) rises to a lamination temperature, the temperature detection device (160) detects the lamination temperature in the lamination space (103), and the control device (170) controls a rotation speed of the lamination roller (140) to laminate the lamination film onto the piece to be laminated based on the lamination temperature.
