Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire door processing technology, specifically a polishing machine for fire door processing. Background Technology
[0002] In the manufacturing process of fire doors, surface polishing of the door panel is a crucial step, as it directly affects the appearance quality, wear resistance, and service life of the fire door. Traditional fire door panel polishing operations usually rely on operators holding polishing machines and controlling the polishing force and trajectory based on their personal experience and feel. However, this manual polishing method has many shortcomings.
[0003] First, traditional handheld polishing relies on the worker's feel for controlling the polishing force and trajectory, resulting in significant differences in polishing effects between different workers. For inexperienced novices, it is difficult to achieve uniform polishing of the fire door panel surface, often leading to unstable polishing quality and affecting the overall quality of the fire door. Second, the polishing process requires workers to repeatedly move the handheld polishing machine across the door panel surface, which not only consumes a lot of physical strength and time but also results in a relatively slow polishing speed, failing to meet the needs of large-scale production and affecting the efficiency of fire door production.

[0014] (Three) beneficial effects

[0016] 1. The polishing machine for fireproof door machining, through the push rod, can effectively control the polishing force of the polishing roller on the surface of the door plate of the fireproof door, so that the polishing quality of the door plate of the fireproof door can be effectively controlled, which avoids the problem that in the traditional way, the polishing of the surface of the door plate of the fireproof door needs to be performed by an operator holding a polishing machine and relying on past experience to apply polishing force, which requires high operation experience and makes it difficult for beginners to uniformly polish the surface of the door plate of the fireproof door, thereby reducing the production quality of the fireproof door and indirectly affecting the production efficiency of the fireproof door.

[0026] Please refer to Figures 1-3The utility model provides a new technical scheme: a polishing machine for fireproof door processing, including work table 1, work table 1 is provided with uniform polishing subassembly, and uniform polishing subassembly is used for polishing the door plate of fireproof door, and uniform polishing subassembly includes inner hexagonal roller 4, hexagonal shaft 5, sliding shaft 7, inclined sliding slot 8, polishing roller 9, push rod 11, first motor 13, door plate fixed disc 15, servo motor 16 and screw rod 17;
[0027] The work table 1 in uniform polishing subassembly is fixedly connected with a plurality of optical axes 2, the outer surface of the plurality of optical axes 2 is slidably connected with a moving plate 3, the moving plate 3 is inverted in the shape of an industry, and the upper end of the plurality of optical axes 2 is fixedly connected with an optical axis fixed plate 10.
[0028] Further, the push rod 11 is fixedly installed on the lower surface of the optical axis fixed plate 10, and the output end of the push rod 11 is fixedly connected with the moving plate 3 through a spring 12.
[0029] Further, the inner hexagonal roller 4 is arranged between the two vertical plates of the moving plate 3, the hexagonal shaft 5 is slidably connected in the moving plate 3, the polishing roller 9 is fixedly sleeved on the middle end of the inner hexagonal roller 4, and the first motor 13 is fixedly installed on the lower surface of the moving plate 3.
[0030] Further, the output shaft of the first motor 13 is fixedly inserted into the hexagonal shaft 5, two inclined sliding slots 8 are arranged at the two ends of the inner hexagonal roller 4 respectively, the inclined sliding slot 8 is arranged in an inclined manner, the inclined sliding slot 8 is in the shape of a closed loop with the head connected with the tail, and the opposite side of the two vertical plates of the moving plate 3 is fixedly connected with a sliding shaft fixed plate 6.
[0031] Further, the two sliding shafts 7 are rotatably connected on the corresponding sliding shaft fixed plates 6 respectively, the two sliding shafts 7 are slidably connected with the inner walls of the corresponding inclined sliding slots 8 respectively, the upper surface of the work table 1 is fixedly connected with two sliding rails 14, and the door plate fixed disc 15 is slidably connected between the two sliding rails 14.
[0032] Further, the servo motor 16 is fixedly installed on the work table 1, the screw rod 17 is fixedly sleeved on the outer surface of the output shaft of the servo motor 16, and the screw rod 17 is screwedly connected with the door plate fixed disc 15.
[0033] Further, in use, the surface of the fire door panel to be polished is placed in the door panel fixing disc 15, and then the polishing roller 9 is started. The output shaft of the polishing roller 9 can drive the hexagonal shaft 5 and the inner hexagonal roller 4 thereon to rotate. When the inner hexagonal roller 4 rotates, the inclined sliding groove 8 thereon can be driven by the sliding shaft 7 to make the inner hexagonal roller 4 rotate along the track of the inclined sliding groove 8. This makes the inner hexagonal roller 4 rotate while continuously reciprocating along the sliding direction of the two moving plates 3 vertical plates, which can make the polishing roller 9 move along the movement track. By controlling the lifting of the output end of the push rod 11, the moving plate 3 can be lifted and lowered by the spring 12 until the polishing roller 9 contacts the door panel in the door panel fixing disc 15. Then, the output end of the push rod 11 is continuously moved downward, and the spring 12 is compressed and deformed.

The polishing force of the polishing roller 9 on the surface of the door panel of the fire door can be effectively controlled by the push rod 11, which can effectively control the polishing quality of the door panel of the fire door. This avoids the problem that in the traditional way, the door panel surface of the fire door needs to be polished by the operator holding the polisher and relying on experience to apply polishing force, which requires high operating experience and makes it difficult for beginners to polish the door panel surface of the fire door uniformly, thereby reducing the production quality of the fire door and indirectly affecting the production efficiency of the fire door.
[0034] Further, by setting the inclined sliding groove 8 and the sliding shaft 7, the movement of the polishing roller 9 on the surface of the door panel of the fire door can be increased in the axial direction, which can make the polishing marks on the surface of the door panel of the fire door more diversified, thereby avoiding the problem that in the traditional way, the single rotation of the polisher can easily cause rotation marks on the surface of the door panel of the fire door, affecting the surface quality and appearance.
[0035] Working principle: when using, the fireproof door panel to be polished is fixed in the door panel fixing disc 15, then the polishing roller 9 is started, the output shaft of the polishing roller 9 can drive the hexagonal shaft 5 and the inner hexagonal roller 4 on it to rotate, when the inner hexagonal roller 4 rotates, the inclined sliding groove 8 on it can be driven by the sliding shaft 7 to make the inner hexagonal roller 4 rotate along the track of the inclined sliding groove 8, which makes the inner hexagonal roller 4 rotate while reciprocating along the sliding direction of the two moving plates 3 vertical plates, which makes the polishing roller 9 on it move along the movement track, by controlling the lifting of the output end of the push rod 11, the moving plate 3 on the spring 12 can be driven to move up and down, until the polishing roller 9 contacts the door panel in the door panel fixing disc 15, then the output end of the push rod 11 continuously moves down, the spring 12 is compressed and deformed, the polishing roller 9 at this time can work on the surface of the fireproof door panel workbench 1 with specified force, at this time, the servo motor 16 is started, which can make the screw 17 on the workbench 1 rotate, so as to drive the door panel fixing disc 15 to move in the two sliding rails 14, which can make the surface of the fireproof door panel be polished by the rotating polishing roller 9.
