Description

Technical Field

[0001] The utility model relates to the technical field of heating mechanisms, in particular to a multifunctional heating mechanism for bending a light guide plate. Background Art

[0002] Light guide plates are usually made of transparent acrylic material and have a specific surface structure. In order to achieve this structure, the light guide plates usually need to be bent or formed to achieve specific optical effects and engineering requirements. Before bending, a special heating mechanism is required to heat and soften them.

[0003] Patent number CN216941792U discloses a hot bending device for PC light guide plates, which includes a bending box, a bending chamber is provided inside the bending box, and a hot pressing mechanism is provided in the bending chamber; the hot pressing mechanism includes a hot pressing roller, which is arranged into a cylindrical structure, and both ends of the hot pressing roller are horizontally connected to the middle of the bending chamber through a connecting rod, and the upper end surface of the hot pressing roller is provided with two symmetrically arranged fixed seats, and the hot pressing roller area between the two fixed seats is placed with a plate to be bent, and the two ends of the plate are fixedly connected to the fixed seats by rubber strips.

[0004] However, the above-mentioned hot bending device has the following defects: 1) It only has one processing chamber, and the loading, heating, bending, unloading, cooling and other processes cannot be carried out simultaneously. After the bending is completed, it takes a long time to wait for it to cool and shape before unloading can be carried out, and the processing efficiency is extremely low; 2) Its heating chamber and bending chamber are in the same space, which causes the electric push rod and related structures to be in a high-temperature environment for a long time, seriously affecting its service life; 3) Its heat dissipation is serious and the energy utilization rate is low; Therefore, in view of the above situation, it is urgent to develop a multifunctional heating mechanism for bending the light guide plate to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

Several grilles are equidistantly distributed on both sides of the limit block and are connected in series with the limit block through the inner rib. The cross section of the grille is arc-shaped.

[0012] Compared with the prior art, the present invention provides a multifunctional heating mechanism for bending a light guide plate, which has the following beneficial effects:

[0013] 1. It uses an independent bending chamber and two heating chambers.
