Description

Technical Field

[0001] The utility model relates to a deviation-correcting and limiting device, belonging to the technical field of thermal insulation board cutting. Background Art

[0002] After the insulation board is produced and formed, it needs to be cut into the required size. Using a conveyor belt to transport the insulation board to the predetermined position below the cutting knife is one of the commonly used methods of transporting the insulation board. In order to facilitate the insulation board to be accurately transported to the bottom of the cutting knife, two limit plates are arranged on the upper side of the conveyor belt. Under the guidance of the two limit plates, the insulation board can be accurately transported to the predetermined position below the cutting knife, thereby realizing deviation correction and limiting.

[0003] Since the width of the insulation board is different, the spacing between the two limit plates needs to be adjustable. The limit plate is installed on the beam directly above the conveyor belt by means of a nut and a screw. The position of the screw in the strip opening on the beam is adjusted to achieve the relative position between the limit plate and the conveyor belt according to the width of the insulation board. At this time, a longer beam is required to expand the adjustment range of the limit plate. When a longer beam is used to limit a cutting board with a narrower width, the length of the beam is not reused, resulting in the beam occupying more space. To avoid a longer beam occupying more space, it is necessary to select beams of different lengths according to the width of the insulation board, resulting in the need to manufacture beams of different lengths, making it difficult for the beam to be universal. Therefore, it is necessary to design a correction and limit device that makes the beam universal while minimizing the space occupied by the beam. Utility Model Content

By increasing or decreasing the number of support plates, the length of the structure formed by the beam and the support plates for supporting the positioning nuts is increased, that is, the number of support plates is increased according to the size of the insulation board. When the insulation board is small, the number of support plates is reduced until no support plates are used. When the insulation board is large, the number of support plates is increased. This is suitable for the needs of correcting and limiting the insulation boards of different widths, and makes the beam universal while minimizing the space occupied by the beam.

[0015] 4. The threaded head on one stud is screwed into the threaded blind hole on another stud to realize the assembly of two adjacent studs. By analogy, multiple studs can be assembled to increase or decrease the number of studs according to the length of the structure formed by the support plate and the beam, without the need to use longer studs.
