Description

Technical Field

[0001] The utility model relates to the technical field of IML diaphragm forming processing, in particular to a heating system suitable for IML diaphragm forming. Background Art

[0002] IML film forming is a process that combines injection molding with labeling. First, the IML film is placed on the corresponding position of the injection mold to ensure that the film is in close contact with the mold. The injection material is added to the injection cavity of the injection molding machine. The injection material is melted and injected into the mold through the heating and pressure system of the injection molding machine. At the same time, the injection molding machine will apply a certain pressure to make the injection material fill the entire mold cavity. During the injection molding process, the IML film is heated by the corresponding heating method to soften it and contact the surface of the injection molded product. After the injection molding is completed, the cooling system will reduce the temperature of the mold and the injection molded product to solidify the injection material.

[0003] Existing heating systems usually use infrared lamps to heat IML films. The temperature distribution of infrared heating is not uniform enough, which will cause inconsistent temperatures in different parts of the product, thus affecting the quality and appearance of the product. In addition, infrared heating has certain restrictions on the selection of materials. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a heating system suitable for IML film forming. The specific technical solution is as follows:

[0005] A heating system suitable for IML film molding comprises a radiator, wherein a plurality of radiators are provided, a heat source radiation zone is provided at one end of the radiator, and at least two groups of wiring tracks are provided at one end of the radiator away from the heat source radiation zone.

[0006] As an improvement of the above technical solution, at least two groups of connecting wires are connected to one end of the radiator away from the heat source radiation zone, and the two groups of connecting wires are provided with wiring points that can move in a straight line along the wiring track at one end away from the radiator. Several wiring terminals are penetrated on the outer sides of the two groups of wiring tracks, and a passage is formed when the wiring point moves into the wiring terminal.

[0007] As an improvement of the above technical solution, the wiring track passes through the connection point, and the connection line is electrically connected to the connection point.

[0008] As an improvement of the above technical solution, at least four groups of grooves are symmetrically provided at both ends of the wiring terminal, wherein one group of the wiring tracks passes through two groups of symmetrically arranged grooves, and the wiring points are inserted into the grooves.

[0009] Beneficial effects of the utility model:

[0010] Through the setting of the radiator, the radiator generates thermal radiation to heat the IML diaphragm. The radiation spectrum has sufficient coverage to meet the requirements of the heated material. Through the setting of the wiring points and terminals, each channel can be individually temperature controlled, and the heating area is more uniform, which solves the problem of external heat marks caused by uneven heating when the IML diaphragm is heated by infrared heating tubes. In addition, the wiring track and the wiring point are coordinated so that the wiring point and the terminal can move freely on the wiring track, which increases the range of adjustment of the radiator position and is more convenient to use.

[0013] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model will be further described in detail. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0014] Existing heating systems usually use infrared lamps to heat IML films. The temperature distribution of infrared heating is not uniform enough, which will cause inconsistent temperatures in different parts of the product, thus affecting the quality and appearance of the product. In addition, infrared heating has certain restrictions on the selection of materials.

[0015] Please refer to Figure 1 As shown, the utility model provides a heating system suitable for IML film molding, including a radiator 10, a plurality of radiators 10 are provided, one end of the radiator 10 is provided with a heat source radiation zone, at least two groups of wiring tracks 20 are provided at the end of the radiator 10 away from the heat source radiation zone, at least two groups of connecting wires 101 are connected to the end of the radiator 10 away from the heat source radiation zone, the two groups of connecting wires 101 are provided with wiring points 11 that can move linearly along the wiring tracks 20 at the ends away from the radiator 10, a plurality of wiring terminals 21 are penetrated on the outer sides of the two groups of wiring tracks 20, and a passage is formed when the wiring point 11 moves into the wiring terminal 21.

[0016] Move several wiring points 11 to connect with several wiring terminals 21, connect the connecting wire 101 with the wiring track 20 circuit, after the circuit is connected, the radiator 10 generates heat radiation, and then move the IML diaphragm to several radiation areas in the heat source to heat the IML diaphragm. The radiation spectrum has sufficient coverage to meet the requirements of the heated material. One end of the connecting wire 101 is connected to the wiring track 20 and the other end is connected to the radiator 10. When the wiring track 20 is powered on, the radiator 10 is powered on through the connection of the connecting wire 101 to heat the IML diaphragm. The radiator 10 includes a radiator and a heat dissipation surface. The radiator 10 is started, the radiator is heated, and the heat is dissipated, diffused, and radiated to the surface of the IML diaphragm through the heat dissipation surface to heat the IML diaphragm.

[0017] The difference from the heating tube heating in the prior art is that the radiator 10 is used, which can be freely adjusted in position, and the difference from the tubular structure heating is that the radiator 10 is used for heat radiation, such as Figure 1 As shown, the radiator 10 can adopt a rectangular structure, and the coverage surface of the radiator 10 can directly cover the entire IML diaphragm, so that the surface of the IML diaphragm can be heated evenly, avoiding the problem of uneven heating surface caused by the heating tube, which causes the appearance of the IML diaphragm to have heat marks. In addition, when the connecting wire 101 adopts a metal braided mesh sleeve or other shell material with a certain support strength and deformable under the action of external force, the position of the connecting wire 101 can be freely adjusted, and only the shell needs to be deformed, and the radiator 10 fixed at the end of the connecting wire 101 can follow the connecting wire 101 to adjust its position, thereby ensuring that the overall structure can be preset to adjust the position of the radiator 10 according to actual production needs.

[0018] In an implementation example, please refer to Figure 1 As shown, the wiring track 20 passes through the wiring point 11, and the connecting wire 101 is electrically connected to the wiring point 11. At least four groups of grooves 211 are symmetrically provided at both ends of the wiring terminal 21, one group of wiring tracks 20 passes through two groups of symmetrically arranged grooves 211, and the wiring point 11 is inserted into the groove 211.

[0019] A groove is provided in the connection point 11, and a connection track 20 is inserted into the groove. A screw is provided on the connection point 11, and the screw penetrates the connection point 11 and is inserted into the groove. There is a cavity between the inner upper wall of the groove and the connection track 20, and the connecting wire 101 is inserted into the cavity and the connecting wire 101 fits the inner upper wall of the groove. The connection point 11 can be freely adjusted on the connection track 20. This structural design expands the range of position adjustment of the radiator 10; a conducting wire is laid in the connection track 20, and a conductive iron sheet is provided in the groove 211. When the connection point 11 is inserted into the groove 211 , insert the conductive iron sheet between the connecting wire 101 and the wiring track 20, then turn the screw, push the screw downward to push the connecting wire 101 to fit the conductor iron sheet, continue to push to make the three parts of the connecting wire 101, the conductive iron sheet and the conducting wire fit tightly, and through the setting of the wiring point 11 and the wiring terminal 21, the connecting wire 101 and the conducting wire are connected, thereby starting the radiator 10. Through the setting of the wiring terminal 21 and the wiring point 11, each channel can be controlled separately. Compared with the infrared heating tube, the temperature control is more precise, the heating area is more uniform, and the product molding effect is more stable.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
