Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic, and more specifically to a novel laminator heating sheet installation device. Background Art

[0002] In the photovoltaic industry, when using the heating sheet of a laminator, the heating sheet is generally installed at the bottom of the heating plate. The traditional method is that the upper part of the heating sheet is tightly attached to the heating plate, the lower part is padded with a heat preservation plate and an insulating plate, and the insulating plate is directly fixed to the heating plate with screws. The disadvantage of this method is that since the heating element has a certain service life and needs to be frequently replaced, the space under the heating plate is very small, and the maintenance is very difficult. It takes a lot of time to remove many screws. Generally, the maintenance time of the equipment on the production line is limited, which requires a very high proficiency of the maintenance workers.

[0003] Therefore, there is an urgent need for a laminator heating sheet installation device. Summary of the Utility Model

[0007] Further optimizing the technical solution, three first support holes are arranged on the connecting rod.

[0008] Further optimizing the technical solution, the two wing nuts are arranged oppositely.

[0009] Further optimizing the technical solution, the size of the bracket is larger than the size of the heat preservation layer.

[0016] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0017] A novel heating sheet installation device for a laminator is arranged below the heating plate 10 and is used for installing a heat preservation layer 8 and a heating sheet 9 on the lower end surface of the heating plate 10; in combination with Figures 1 to 2 as shown, it includes a connecting rod 1, a first support hole 11, a threaded rod 2, a wing nut 21, a swing arm 3, a rotating shaft 4, a bracket 5, a second support hole 51, a frame 7, and an opening 71.

[0018] The frame 7 is a frame in a box shape and is horizontally arranged below the heating plate 10.

[0019] Three openings 71 are arranged on the left end surface of the frame 7, and the threaded rod 2 is passed through the openings 71. Wing nuts are respectively arranged at positions on both sides of the threaded rod 2 with respect to the openings 71, and the two wing nuts are arranged oppositely.

[0020] The right end of the threaded rod 2 is connected with a connecting rod 1. The connecting rod 1 is horizontally arranged inside the frame 7, and a plurality of first support holes 11 are uniformly arranged on the connecting rod 1. The first support holes 11 are opened upward, and there are three first support holes 11 on the connecting rod 1. The frame 7 is provided with rotating shafts 4, and the rotating shafts 4 are all located at positions above the first support holes 11. Swing arms 3 are sleeved on the rotating shafts 4, the end parts of the swing arms 3 are located in the first support holes 11, and when the swing arms 3 are vertical, the length of the part extending out of the frame 7 is greater than or equal to the length from the bottom of the second support hole 51 to the upper edge of the frame 7.

[0021] The top end of the swing arm 3 is movably connected to a horizontally arranged bracket 5, and the size of the bracket 5 is larger than that of the heat insulation layer 8. The bottom end surface of the bracket 5 is provided with a second support hole 51 for accommodating the top end of the swing arm 3. The distance between the frame 7 and the heating plate 10 is greater than the sum of the thicknesses of the heating sheet 9, the heat insulation layer 8, and the bracket 5.

[0022] When the utility model is actually used, first move the butterfly nut on the left side of the frame outside the threaded rod 2 to the left by a certain distance, and then rotate the butterfly nut on the right side to move the connecting rod to the right. At this time, the swing arm 3 rotates counterclockwise around the rotating shaft 4, and the swing arm 3 drives the bracket 5 to move downward, forming a space sufficient to accommodate the heat insulation layer 8 and the heating sheet 9 between the heating plate 10 and the bracket 5. Lay the heating sheet 9 flat on the heat insulation layer 8, and then place the heat insulation layer 8 together with the heating sheet 9 on the bracket 5 and push the heat insulation layer 8 along the bracket 5 to the designated position.

[0023] Move the butterfly nut on the right side of the frame 7 on the threaded rod 2 to the right by a certain distance, and then rotate the butterfly nut on the left side to move the connecting rod 1 to the left. At this time, the swing arm 3 rotates clockwise around the rotating shaft 4, and the swing arm 3 drives the bracket 5 to rise until the heating sheet 9 is in close contact with the heating plate 10. Rotate the butterfly nut on the right side of the frame 7 to the left to give a certain pre-tightening force to ensure that neither of the two butterfly nuts loosens.
