Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a laminator, and particularly to a fast-cooling laminator capable of separating power.

[0002]

[Prior art]

 The conventional laminator disclosed in Utility Model Registration No. 3039028 mainly includes a base, a pair of rolling pressure bonding rolls, a heat conducting shell, and a driving device. The heat conductive shell therein includes an upper heat conductive shell and a lower heat conductive shell, and is configured by pairing them. Further, upper and lower roll holes are recessed in the upper and lower heat conducting shells to cover and cover the rolling press roll, and the laminating material entered from the entrance is covered by the heat conducting shell. The temperature of the film is quickly increased by receiving the heat, and the temperature at which the film is adhered is maintained. After the rolling press of the rolling press roll, the laminating operation is completed.

[0003]

[Problems to be solved by the invention]

 However, the conventional laminator has the following disadvantages. (1) The material to be laminated is subjected to rolling pressure bonding through a rolling pressure bonding roll to complete the laminate, and is also in the range where the upper and lower heat conducting shells are wrapped. high. For this reason, the film of the already completed laminate is again affected by the high temperature, and local peeling may occur. Alternatively, there is a phenomenon that a gap is formed inside, which affects the quality of the laminate.

(2) The driving device is fixed, meshes with the rolling press roll, transmits power, and cannot be temporarily separated. In other words, when a user is working on a laminate, it is not possible to immediately stop work on a defective laminate and remove it. If the user turns off the power, the rolling crimping roll cannot engage with the motor and rotate, so the sandwiched product cannot be removed. After removing all the laminators, the sandwiched lamination can be completely removed, but it is troublesome enough.

[0005] (3) In a general laminator, the temperature at the inlet is mostly observed only by the temperature observation unit, so that the temperature of the rolling press roll cannot be measured accurately. Because of this, the laminator lamination temperature is not accurate. As mentioned above, the conventional laminator has three disadvantages. The already laminated film is peeled or gaps are formed again by high temperature. It is very troublesome for the user to extract defective lamination during work. In addition, the temperature of the rolling press roll cannot be measured accurately, and the laminating temperature of the laminator is not accurate.

[0006] Therefore, the purpose of the present invention is to cool quickly, improve the quality of the laminate by avoiding reheating at high temperature to the already completed laminate, and to allow the user to perform the process during the lamination process. An object of the present invention is to provide a laminator that protects the laminate and the laminator by smoothly extracting the defective laminate when a defect is found.

[0007]

[Means for Solving the Problems]

 According to an embodiment of the present invention, there is provided a laminate including a pair of heat-conducting shells, a pair of rolling press rolls, and a driving device. A pair of heat-conducting shells are paired and provided between opposed fixed bases of the laminator, the first side of which is wrapped to form a heating zone and includes an entrance. The other second side forms a cooling port and goes directly to the delivery outlet. A pair of rolling pressure rolls are pivotally mounted within the pair of heat conducting shells. Further, each rolling press roll can be operated or rotated or detached by the driving device. With this, the material to be laminated is sent from the entrance to the pair of rolling pressure rolls, and before the lamination proceeds, the heating section formed by wrapping and covering the pair of heat conducting shells first heats and raises the temperature. . The material to be laminated enters the cooling port immediately after completing the laminating operation through the rolling pressure bonding of the pair of rolling pressure rolls, and desorbs from the heating of the pair of heat conducting shells. It cools quickly and is delivered from the delivery outlet. In the laminating process, the drive device and the pair of rolling pressure rolls can be separated from each other, so that the faulty laminate can be quickly extracted from the laminator, and the material to be laminated and the laminator can be separated. Has the effect of protecting.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 7, the laminator of the present embodiment includes a pair of fixed bases 1, 1 ′, a pair of rolling press rolls 2, 2 ′, a pair of heat conducting shells 3, 3 ′, and a driving device 4. . A pair of fixed bases 1, 1 ′ are provided in a laminator shell 10. A pair of rolling pressure rolls 2, 2 'are pivotally mounted between the fixed bases 1, 1'. A pair of heat conducting shells 3, 3 'are installed between the fixed bases 1, 1' and enclose the rolling press rolls 2, 2 ', and the first of the heat conducting shells 3, 3'. In side A, an enclosed heating zone H is formed and includes an entrance 30. The second side B of the heat-conducting shells 3, 3 ′ forms a cooling port 35 and goes straight to the delivery and outlet 5. Further, a driving device 4 is elastically pivotally mounted on the fixed base 1, and operates the two rolling press rolls 2, 2 'to rotate. Alternatively, the driving device 4 and the two rolling pressure rolls 2, 2 'can be separated. Thereby, the material 6 to be laminated is fed from the entrance 30 to the rolling press rolls 2 and 2 ′, and is heated by the heating section H composed of the heat conducting shells 3 and 3 ′ before the roll pressing of the laminate proceeds. After the temperature is increased and the rolled crimping rolls 2 and 2 'are passed through the rolling crimping rolls, they immediately enter the cooling openings 35 of the heat conducting shells 3 and 3' and are quickly cooled by external heat conduction. Then, it is sent out along the sending-out deriving unit 5. As a result, it is possible to avoid that the laminated material 6 which has already been laminated is heated again by receiving a high temperature, and the quality of the laminate can be improved.

The fixed bases 1, 1 ′ of the present embodiment can be connected upward from inside the shell 10 of the laminator. There are at least two shaft holes 11, 11 'on each of the fixed bases 1, 1', and the rolling press rolls 2, 2 'are pivotally mounted corresponding to the shaft holes 11, 11', respectively. In addition, the wheel surfaces of both rolling pressure rolls 2, 2 'are brought into contact with each other.

The core shafts 21, 21 ′ of the rolling press rolls 2, 2 ′ of the present embodiment may be made of a metal material. In addition, the outer covering layers 22, 22 'are wrapped around the outer surfaces of the core shafts 21, 21'. The outer cover layers 22, 22 'may be made of a material such as silicone rubber. Of course, the invention can be applied to other types of rolling pressure rolls. When the rolling crimping rolls 2, 2 'are pivotally mounted between the fixed bases 1, 1', the respective core shafts 21, 21 'on one side protrude outside the fixed base 1, and the transmission gears 23, 23' 'Is installed. As a result, the transmission gears 23, 23 'of the two rolling press rolls 2, 2' are always meshed with each other and transmitted, and one of the transmission gears 23 is meshed with the drive gear 432 of the drive unit 4 and transmitted. Thus, when the user activates the driving device 4, the driving gear 432 rotates the two rolling pressure bonding rolls 2 and 2 ′ in association with each other to advance the rolling pressure bonding on the transferred laminate 6. To carry out the laminating operation, and to send out the laminate 6 to the outside along the feed-out part 5 at the rear.

The heat-conducting shells 3 and 3 ′ are engaged with each other and fastened between the two fixed bases 1 and 1 ′. Each heat-conducting shell 3, 3 ′ includes a concave vessel 31, at least one heating unit 32, a covering wall 33, at least one temperature-sensitive unit 34, and a cooling port 35. The concave tank 31 is provided on the outer end surface of each of the heat conducting shells 3, 3 'in the vertical direction. At least one heating unit 32 can be made of a material having a positive temperature coefficient (PTC: Positive Temperature Coefficient) or the like, is provided over the concave tank 31, and the heating unit 32 is provided with a power supply. After turning on the power through the two electrodes, the temperature of the heating unit 32 is increased. Further, a large number of push plates 321 are fastened to both sides of the concave tank 31, and press the heating unit 32 downward into the concave tank 31. The envelope cover wall 33 extends continuously from the first side A of each of the heat conducting shells 3 and 3 ', and after the two heat conducting shells 3 and 3' have been mated, the two heat conducting shells 3 and 3 '. In the wrapping wall 33 of 3 ', a heating zone H is formed, and at least the first side A of the rolling press roll 2, 2' is wrapped therein. Furthermore, the entrance 30 is formed and used by the user to transfer the objects 6 to be laminated. At least one temperature sensing unit 34 is clamped by the fixing plate 341 near the periphery of the entrance 30 and monitors the temperature near the entrance 30. The cooling port 35 is located on the second side B after the two heat-conducting shells 3 and 3 'have been joined, and the second side B of the two rolling pressure bonding rolls 2 and 2' and the outside space having a large volume. Communicate with each other.

The two heat-conducting shells 3, 3 ′ of the present embodiment almost completely cover and cover the first side A of both rolling pressure rolls 2, 2 ′, and only the lamination 6 except the entrance 30. After the power is turned on and the temperature of the heating unit 32 is raised, heat is quickly transferred to each portion of each of the heat conducting shells 3 and 3 '. In addition, since the temperature of the area covered by the two heat-conducting shells 3 and 3 ′ rises as a result of radiant conduction, this keeps the entire heated section H at the cohesion temperature of the film 61. As a result, the material 6 to be laminated receives the heat of the heating section H and rises in temperature before being subjected to the laminating rolling press through the two rolling press rolls 2 and 2 ′, and then passes through the both rolling press rolls 2 and 2 ′. After the bonding of the rolling pressure bonding is performed, the laminated material 6 having completed the lamination moves to the second side B of the rolling pressure bonding rolls 2, 2 '. That is, the laminate 6 moves to the cooling port 35 on the second side B of both the heat conductive shells 3 and 3 ', and the laminated material 6 after rolling and contacting with a large area comes into contact with the outside, so that heat is quickly dissipated, and the temperature decreases. In addition, it is sent out to the outside across the sending-out lead-out section 5 between the fixed bases 1 and 1 '. As described above, the laminator of this embodiment prevents the laminate 6 from being heated again by the heat-conducting shells 3, 3 'after being laminated by the rolling-pressing rolls 2, 2'. And the quality of the laminate can be ensured.
