[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] Example 1
[0020] like Figure 1-3 As shown, an EVA film hot spot device includes a cylinder 1, a hot spot seat 2, a hot spot head 3, and a buffer mechanism 4. The cylinder 1 is installed on a hot spot mounting plate 5, and the entire device is fixed by the hot spot mounting plate 5. The telescopic end of the cylinder 1 is connected to the buffer mechanism 4, and is elastically connected to the hot spot seat 2 through the buffer mechanism 4. A heating tube 6 is provided in the hot spot seat 2, and a hot spot head 3 is provided on both sides below the hot spot seat 2. The hot spot head 3 is provided with a plurality of hot spots 31 arranged in parallel at intervals. The hot spots 31 are square in shape. The hot spot head 3 is made of red copper. The hot spots 31 are arranged in a rectangular or square shape, which is easier to process. Figure 3 As shown, in this embodiment, four hot spots are used, which are arranged at intervals. Compared with a single hot spot, the hot spot area is larger, the hot spot effect is better, and the fixation is more firm, ensuring that the EVA film does not shift. The hot spot device of the utility model has a simple and compact overall structure and is easy to operate. During hot spot operation, the buffer mechanism 4 reduces the impact between the hot spot head 3 and the glass, thereby improving the working stability of the device, reducing damage to the device, and extending the service life of the device.
[0021] Among them, Figure 1-2As shown, the buffer mechanism 4 includes a buffer rod 41, a spring 42, a limit nut 43, a guide sleeve 44, and a limit plate 45. The buffer rod 41 is connected to the centering joint provided at the telescopic end of the cylinder 1. The lower end of the buffer rod 41 is inserted in the guide sleeve 44 and slidably connected with the guide sleeve 44. The guide sleeve 44 is connected to the hot seat 2 through a buffer seat plate 46. The upper end of the buffer rod 41 is provided with a limit nut 43, and the bottom is provided with a limit plate 45 located below the guide sleeve 44. The spring 42 is sleeved on the outside of the buffer rod 41, one end of which is in contact with the limit nut 43, and the other end is in contact with the guide sleeve 44. When hotting, the cylinder 1 extends, driving the buffer rod 41 and the hot seat 2 to descend, and the spring 42 is compressed. When the hot head 3 contacts the EVA film, the elastic force of the spring 42 can reduce the impact between the hot head 3 and the glass.
