Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of roller casting rubber, in particular to a cleaning structure for the bottom of a roller. Background Art
[0002] The polyurethane casting rubber of the roller adopts the polyurethane hot vulcanization process, which uses high-quality hot vulcanized rubber. The high-performance polyurethane is directly poured and vulcanized on the surface of the roller, giving the roller extremely strong adhesion and excellent wear resistance.
[0003] Most of the rollers on the roller conveyor will undergo a hot vulcanization process. By adding hot vulcanized polyurethane plastic to the surface of the roller, not only the friction of the roller can be increased, but also the service life of the roller can be increased.
[0004] However, the polyurethane plastic on the surface of the roller is prone to sticking to dust on the surface of objects during use. Over time, the viscosity of the polyurethane plastic on the surface of the roller is easily reduced, thereby reducing the friction between the roller and the object, which can easily cause the roller conveyor to slip when transporting goods.

[0023] like Figures 1-4 As shown, the utility model provides a technical solution: a cleaning structure for the bottom of a drum, comprising a drum body 1, a drum shaft 2 is fixedly installed at both ends of the drum body 1, a rubber 5 is fixedly installed on the outer wall of the drum body 1, and a cleaning mechanism 3 for cleaning the rubber 5 is provided on the drum shaft 2. By setting the cleaning mechanism 3, dust attached to the surface of the rubber 5 can be cleaned to avoid dust accumulation causing the viscosity of the rubber 5 to decrease, thereby avoiding the drum body 1 from slipping when conveying articles. A knocking mechanism 4 is provided on the cleaning mechanism 3. By setting the knocking mechanism 4, the brush 32 can be self-cleaned, so that the brush 32 can better clean the rubber 5.
[0024] The above-mentioned cleaning mechanism 3 includes a ball bearing 31, a brush 32, a motor 33, a counterweight rod 34, a limit groove 35, and a crankshaft 36; the ball bearing 31 is fixedly mounted on the outer wall of the roller shaft 2, and the outer wall of the ball bearing 31 is fixedly mounted with a counterweight rod 34. When the roller conveyor drives the roller body 1 and the roller shaft 2 to rotate, the ball bearing 31 cooperates with the deadweight of the counterweight rod 34 to keep it in a stable vertical state at all times. The brush 32 is slidably connected to the inner wall of the counterweight rod 34, and the brush 32 passes through the counterweight rod 34. The crankshaft 36 pushes and pulls the brush 32 back and forth on the inner wall of the counterweight rod 34. The brush 32 slides and fits the outer wall of the rubber 5. The rotation of the roller body 1 and the reciprocating movement of the brush 32 can sweep away the dust attached to the surface of the rubber 5 to prevent dust accumulation from decreasing the viscosity of the rubber 5. A limiting groove 35 is provided on the brush 32, and the motor 33 is fixedly mounted on the outer wall of the counterweight rod 34. A crankshaft 36 is fixedly mounted on the output end of the motor 33. The motor 33 is started and the crankshaft 36 is driven to rotate by the motor 33. The outer wall of the crankshaft 36 fits the inner wall of the limiting groove 35. When the crankshaft 36 rotates, it fits the inner wall of the limiting groove 35 and moves back and forth, pushing and pulling the brush 32 back and forth.
[0025] The above-mentioned knocking mechanism 4 includes a rotating rod 41, a driven bevel gear 42, a driving bevel gear 43, a glue stick 44, and a steel ball 45; the rotating rod 41 is rotatably connected to the inner wall of the counterweight rod 34, and the rotating rod 41 passes through the counterweight rod 34, and the end of the rotating rod 41 close to the counterweight rod 34 is fixedly installed with the driven bevel gear 42, and the end of the crankshaft 36 away from the motor 33 is fixedly installed with the driving bevel gear 43. When the crankshaft 36 rotates, it will drive the driving bevel gear 43 to rotate synchronously, and the driving bevel gear 43 is meshed with the driven bevel gear 42. When the driving bevel gear 43 rotates, the driven bevel gear 42 meshed with it can be driven The movable rotating rod 41 rotates, and a glue stick 44 is fixedly installed on the outer wall of the rotating rod 41. A steel ball 45 is fixedly installed on the end of the glue stick 44 away from the rotating rod 41. When the rotating rod 41 rotates, the glue stick 44 can drive the steel ball 45 to make a circular motion around the rotating rod 41. The outer wall of the steel ball 45 fits the bottom of the brush 32. When the steel ball 45 makes a circular motion around the rotating rod 41, the steel ball 45 will repeatedly knock on the bottom of the brush 32. The repeated knocking of the steel ball 45 on the brush 32 can shake off the dust attached to the surface of the brush 32, thereby preventing dust from accumulating on the surface of the brush 32 and affecting the effect of the brush 32 on cleaning the rubber 5.
[0026] Working principle: After the roller body 1 is installed on the roller conveyor, the deadweight of the counterweight rod 34 can be used to keep it in a vertical state. When the roller conveyor drives the roller body 1 and the roller shaft 2 to rotate, the ball bearing 31 can be used to keep the counterweight rod 34 in a stable vertical state. At the same time, the motor 33 is started, and the crankshaft 36 is driven to rotate by the motor 33. While the crankshaft 36 rotates, it will fit back and forth on the inner wall of the limit groove 35 and push and pull the brush 32 back and forth, so that the brush 32 slides back and forth on the inner wall of the counterweight rod 34. At the same time, the brush 32 will fit back and forth on the outer wall of the rubber 5. At this time, the self-rotation of the roller body 1 and the reciprocating movement of the brush 32 can sweep away the dust attached to the surface of the rubber 5, avoiding the accumulation of dust and the decrease in the viscosity of the rubber 5, thereby avoiding the roller body 1 from slipping when conveying items, so that the roller body 1 can better convey items.
[0027] When the crankshaft 36 rotates, it will drive the driving bevel gear 43 to rotate synchronously. When the driving bevel gear 43 rotates, it can cooperate with the driven bevel gear 42 engaged with it to drive the rotating rod 41 to rotate. When the rotating rod 41 rotates, it can cooperate with the glue stick 44 to drive the steel ball 45 to make a circular motion around the rotating rod 41. At the same time, the steel ball 45 will repeatedly knock on the bottom of the brush 32. The repeated knocking of the steel ball 45 on the brush 32 can shake off the dust attached to the surface of the brush 32, preventing dust from accumulating on the surface of the brush 32 and affecting the cleaning effect of the brush 32 on the rubber 5, so that the brush 32 can better clean the rubber 5.
[0028] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
