Description

Technical Field

[0001] The present invention relates to the technical field of asphalt shingle production, and specifically relates to an efficient and stable asphalt shingle production line and its usage method. Background Art

[0002] Asphalt shingles are a new type of roofing material used for building roof waterproofing. The application range of asphalt shingles is not limited to villas. It can be used for any building that can meet the construction requirements: the thickness of the cement roof is not less than 100 mm, and the thickness of the wood structure roof is not less than 30 mm. In addition to all the functions of tiles, it also has a characteristic that it is especially suitable for roofs with slopes of 0 - 90 degrees and roofs of any shape. When producing asphalt shingles, first, asphalt needs to be processed into a matrix, then sandblasting is carried out on the surface of the asphalt, followed by pressing to make the sand grains firmly adhere to the asphalt, then cooling is carried out, and finally it is cut. When processing asphalt into a matrix, a feeding device is required. However, the feeding devices currently used in the market have a relatively simple structure. When feeding, the feeding port is easily blocked, resulting in unsmooth feeding and reduced feeding efficiency. At the same time, after completing the above production processes of asphalt shingles on the production line, quantitative length cutting is required. Since the asphalt shingles are attached to the workbench, it is inconvenient for workers to remove the asphalt shingles from the workbench. In addition, the cutting knife cannot be adjusted, and the cutting size of the asphalt shingles cannot be freely set, which is not convenient for use. Summary of the Invention

A method for using an efficient and stable asphalt shingle production line, characterized by: The asphalt shingle production line according to any one of claims 1 to 9 comprises the following steps: (1) When producing asphalt shingles, install the lower hopper at the material inlet of the asphalt shingle processing line; (2) Then insert the threaded rod through the side plate, and rotate the buckle block on the outside of the threaded rod to adjust the position of the buckle block according to usage requirements; (3) After the adjustment is completed, buckle the buckle block inside the side plate. The annular limit plate inside the side plate will be buckled with the outer side of the buckle block through interference fit, thereby supporting and fixing the lower hopper; (4) Then, the raw material is placed inside the lower hopper and the first motor is started; (5) The first motor drives the transmission rod to rotate, so that the stirring rod outside the transmission rod stirs the raw materials; (6) At the same time, the first connecting plate and the pressure rod at the bottom of the transmission rod squeeze the second connecting plate to move the fixed rod downward, causing the spring on the outside of the fixed rod to deform; (7) The fixed rod moves up and down to clear the bottom of the hopper to avoid blockage of raw materials and slow material discharge; (8) After the material falls from the lower hopper onto the asphalt shingle processing line, it is processed on the asphalt shingle processing line; (9) After the processing, the asphalt shingles are output to the connecting table and then enter the cutting table; (10) When the asphalt shingles enter the cutting table, as the asphalt shingles are continuously transported; (11) The first cutter cuts the asphalt shingles, and then the electric push rod drives the second cutter to move downward to cut; (12) When the second cutter moves, it drives the auxiliary block to move, and the auxiliary block slides along the slide bar. The staff then takes out the cut asphalt shingles for packaging; (13) When removing asphalt shingles, the worker steps on the pedal, which drives the connecting plate to move upward, and the connecting plate drives the long plate to move upward. The long plate slides upward along the cutting table, and at the same time, the long plate drives the upper top plate; (14) Use the top plate to push the asphalt shingles upwards so that there is a certain distance between the asphalt shingles and the countertop, making it easier for the staff to remove the asphalt shingles; (15) When the size of the asphalt shingle cutting needs to be adjusted, the second motor is started, and the second motor drives the threaded rod to rotate. The rotation of the threaded rod drives the slider to slide along the cutting table. At the same time, the slider drives the first cutter to move, so that the size of the asphalt shingle cutting can be freely set.
