[0020] With the above structure installed, when the laminating material and laminating film are inserted along the input port 101 during use, the heating component 130 activates, and the temperatures of the laminating roller 140, laminating space 103, and preheating space 104 rise in stages, the guide roller 120 rotates, introducing the laminating material and laminating film into the preheating space 104, where the temperature of the laminating material and laminating film rises in stages, and as the guide roller 120 transports the laminating material and laminating film to the laminating roller 140, the heating component 130 raises the temperature of the laminating roller 140 and the laminating space 103 to a first laminating temperature te1, with the distance the laminating film and laminating material travel through being h. The laminating roller 140 presses and fixes the laminating film onto the laminating material, and when using the laminator, there is no need to start the laminator and wait for the laminating roller to reach the laminating temperature. The laminating film and laminating material can be fed directly into the input port, and the laminating roller 140 can be heated to the first laminating temperature te1 using the transport time of the laminating film and laminating material by the guide roller, thereby performing the laminating process, which is highly convenient for the user.

[0021] In this embodiment, the main body 110 includes an upper mounting member 111 and a lower mounting member 112, the upper mounting member 111 is connected to the lower mounting member 112, the preheating space 104 is formed between the upper mounting member 111 and the lower mounting member 112, both the upper mounting member 111 and the lower mounting member 112 are provided with heat conduction plates 113, the heat conduction plates 113 extend toward the guide roller 120 along the surface of the upper mounting member 111 and / or the surface of the lower mounting member 112, and the preheating space 104 is formed between the two heat conduction plates 113. By installing the above structure, the upper mounting member 111 and the lower mounting member 112 are connected to form a substantially sealed preheating space 104, allowing the heating component 130 and the laminating roller 140 to be housed within the preheating space 104, protecting the heating component 130 and the laminating roller 140, preventing contamination of the heating component 130 and the laminating roller 140 by external foreign matter, improving the heating efficiency, and quickly bringing the laminating roller 140 to the laminating temperature. Furthermore, the heat conduction plate 113, which is provided protruding from the surface of the upper mounting member 111 and / or the surface of the lower mounting member 112, can conduct heat, and the preheating space 104 formed between the two heat conduction plates can preheat the laminate film and laminate member, raising the temperature of both, thereby allowing the temperature of the laminate film and laminate member to reach the lamination temperature during lamination by the laminating roller 140, and improving the lamination efficiency of the product.

[0022] In this embodiment, a first guide portion 114 is provided at the end of the heat conduction plate 113, and the two first guide portions 114 are spaced apart from each other. With the above structure in place, the two first guide portions 114 are spaced apart from each other, forming a trumpet-shaped opening design at the entrance to the preheating space 104. When the guide roller 120 transports the laminate film and laminate member during use, the laminate film and laminate member can easily enter the preheating space 104, preventing the laminate film and laminate member from getting stuck at the entrance to the preheating space 104, thereby improving the efficiency of product use and reducing the failure rate.

[0023] In this embodiment, guide plates 115 are provided on both the upper mounting member 111 and the lower mounting member 112, a guide passage 105 is formed between the two guide plates 115, and the guide passage 105 and the discharge port 102 are provided opposite each other. With the above structure installed, guide plates 115 are provided on both the lower end of the upper mounting member 111 and the upper end of the lower mounting member 112, the two guide plates 115 are provided opposite each other, a guide passage 105 is formed between them, the laminate film and laminate member after heat-seal fixing can be transported in stages along the guide passage 105 and finally discharged along the discharge port 102, making it easy for the user to obtain the laminated finished product, preventing the laminate film and laminate member from getting stuck in front of the discharge port 102, and improving the lamination efficiency of the product.

[0024] In this embodiment, a second guide portion 116 is provided on the side of the two guide plates 115 facing the laminating roller 140, and the two second guide portions 116 are spaced apart from each other. With the above structure installed, when in use, the two spaced-apart second guide portions 116 form a trumpet-shaped opening, which faces the laminating roller 140 directly. After the laminating film and laminating member are heat-pressed and laminated by the laminating roller 140, they enter the guide passage 105 along the opening and are further transported along the guide passage 105 to the discharge port 102, smoothly leading out the laminated member, preventing malfunctions such as jamming, and improving the efficiency of product use.

[0025] In this embodiment, a drive unit 150 is further included, which is provided within the main body 110 and connected to the laminating roller 140 and the guide roller 120 via a gear set 151, and the drive unit 150 drives the rotation of the laminating roller 140 and the guide roller 120. With the above structure installed, the output terminal of the drive unit 150 rotates, moving the gear set 151, which in turn moves and rotates the laminating roller 140 and the guide roller 120, which include two laminating rollers 140, which are provided facing each other vertically and rotating in opposite directions; similarly, there are also two guide rollers 120, which are provided facing each other vertically and rotating in opposite directions.

[0026] In this embodiment, a temperature detection device 160 and a control device 170 are further included, wherein the temperature detection device 160 is provided within the main body 110, detects the temperature t in the laminate space 103 and outputs a first electrical signal, and the control device 170 is electrically connected to the temperature detection device 160 and the drive device 150, and the control device 170 receives the first electrical signal generated by the temperature detection device 160 and is used to adjust the rotational speed of the drive device 150 based on this.With the above structure installed, when in use, the laminating material and laminating film are fed along the input opening 101, the drive unit 150 operates at a preset initial rotation speed v0, at which time the heating component 130 operates, the temperature of the laminating roller 140, the laminating space 103 and the preheating space 104 rises in stages, the guide roller 120 rotates, introducing the laminating material and laminating film into the preheating space 104, and within the preheating space 104, the temperature of the laminating material and laminating film rises in stages, When the side roller 120 transports the laminating material and laminating film to the laminating roller 140, the heating component 130 raises the temperature of the laminating roller 140 and the laminating space 103 to a first laminating temperature te1, with h being the distance the laminating film and laminating material travel. The temperature detection device 160 detects this first laminating temperature te1 and outputs a first electrical signal. Based on this signal, the control device 170 adjusts the rotational speed of the drive device 150 to v1; depending on the temperature, The degree of melting of the laminate film varies, and when the temperature is low, in order to ensure a tight bond between the laminate film and the laminate material, it is necessary to increase the time that the laminating roller 140 presses the laminate film onto the laminate material. Therefore, the control device 170 controls the drive device 150 to reduce the rotation speed, thereby increasing the contact time between the laminating roller 140 and the laminate film and laminate material, thereby increasing the success rate of the lamination process and ensuring the effect of the lamination process; also, one set of laminating sheets After the lamination of the film and laminate material is completed, when the next set of laminate film and laminate material is fed along the input opening, the heating component 130 continues to operate, further increasing the temperature of the laminating roller 140 and the laminating space 103. When the next set of laminate material reaches the laminating roller 140, the laminating roller 140 reaches a higher lamination temperature te2. At this point, the rotational speed of the drive unit 150 can be increased to v2 to improve the efficiency of the lamination process.Preferably, the control device 170 is further provided with a button 171, which the user can use to select a mode corresponding to a different laminating film thickness. In this case, the control device 170 adjusts the rotation speed of the drive unit 150. Generally, the thicker the laminating film, the higher the required laminating temperature and the longer the time required for the laminating rollers to contact and heat-seal the laminating film. Therefore, when the laminating film is thick, the control device 170 controls the drive unit 150 to reduce its rotation speed.

[0027] In this embodiment, the temperature detection device 160 is further used to detect whether the temperature t in the laminating space 103 falls below the preset temperature T, and to output a second electrical signal when the temperature t in the laminating space 103 falls below the preset temperature T. The control device 170 receives the second electrical signal and controls the heating component 130 to heat up. With the above structure installed, when the laminating film and laminating member pass through the laminating roller 140 during use, the laminating film and laminating member absorb a certain amount of heat, causing the temperature of the surface of the laminating roller 140 to decrease. When the temperature detection device 160 detects this decrease in temperature, it outputs a second electrical signal, and the control device 170 controls the heating component 130 to operate, raising the temperature of the surface of the laminating roller 140 back up to the laminating temperature, maintaining the temperature near the laminating temperature, ensuring temperature stability, and further ensuring the laminating effect.

[0028] In this embodiment, the heating component 130 includes a plurality of heating members 131, which are arranged around the laminating roller 140. By arranging the plurality of heating members 131 around the laminating roller 140 with the above structure, the heating effect can be enhanced, the temperature in the laminating space 103 can be made uniform, and the laminating effect can be improved. Preferably, the heating members 131 are high-output heating members such as heat pipes, which can increase the heating speed and enhance the laminating effect.

[0029] In this embodiment, a receiving plate 180 is further included, the receiving plate 180 is provided on the side of the main body 110 closer to the discharge port 102, extends along the plane in which the discharge port 102 is located, and the upper surface of the receiving plate 180 is below the discharge port 102. With the above structure installed, when in use, the laminate member and laminate film are laminated by the laminating roller 140 and then discharged along the guide passage 105 and the discharge port 102, and the receiving plate 180 can effectively support the laminated laminate member and prevent contamination and damage.

[0030] In this embodiment, the two heat conduction plates 113 extend toward the input opening 101 along the surface of the mounting member 111 and the surface of the lower mounting member 112, respectively; the heat received by the upper mounting member 111 and the lower mounting member 112 is conducted onto the heat conduction plates 113, and can be heated until the laminating member and laminating film reach the laminating temperature as they pass through the preheating space 104.

All modifications, equivalent substitutions, and improvements made within the concept and principles of the present invention should be included within the scope of protection of the present invention.
