Detailed Description
The device for removing impurities on the surface of the rod material is further described by combining with figures 1 to 2.
The utility model provides a be used for surperficial edulcoration device of pole material, characterized by: comprises a bottom plate 2, a cleaning wheel set, a take-up pan 1 and an impurity adsorption component 5.
The cleaning wheel set comprises two cleaning wheels 3 arranged in parallel, cleaning grooves 321 capable of cleaning the surfaces of the rods 4 are formed in the circumferential side wall of each cleaning wheel 3, each cleaning groove 321 is of a semicircular structure, the cleaning grooves 321 in the two cleaning wheels 3 correspond to each other and form a circular cleaning channel 34, rotating shafts 33 of the two cleaning wheels 3 are vertically installed on the bottom plate 2 through bearings 35, the two rotating shafts 33 are connected through connecting pieces 36 to achieve synchronous rotation, one of the rotating shafts 33 is connected with a driving part 37, the connecting pieces are gears 36 in the embodiment, the driving part 37 is a motor, the motor is connected with the rotating shafts 33 through the gears 36, and the two cleaning wheels 3 are driven to rotate synchronously. The receiving tray 1 is installed on the bottom plate 2 through the supporting columns 21 and is located below the cleaning wheel set so as to receive the cleaned impurities. The impurity adsorbing assembly 5 comprises an adsorbing cover 51 and a filter screen 52, the adsorbing cover 51 is fixed on the material receiving tray 1 through a support column 6 and is positioned on one side of the cleaning wheel 3, which is back to the cleaning channel 34, the adsorbing cover 51 is connected with a suction pump through a connecting pipe 54 to form an adsorbing channel 53 in the adsorbing cover 51, and a suction port of the adsorbing channel 53 corresponds to the cleaning groove 321, namely, one side of the cleaning groove 321, which is back to the cleaning channel 34, is positioned in the suction port of the adsorbing channel 53; the filter net 52 is disposed in the suction passage 53, and an opening 5121 is formed in the bottom wall of the suction cover 51 on the side of the filter net 52 facing the suction port.
In operation, the present invention is installed on a thread rolling machine so that the rod material 4 passes through the cleaning channel 34 before entering the thread rolling machine. The motor drives the two cleaning wheels 3 to rotate along the direction opposite to the conveying direction of the rod material 4 through the gear 36, and the surface of the rod material 4 is wiped by the cleaning groove 321, so that the surface of the rod material 4 is cleaned. Because the two semicircular cleaning grooves 321 are matched to form the circular cleaning channel 34, the rod material 4 can be wiped completely at 4360 degrees, and the surface cleaning comprehensiveness of the rod material 4 is obviously improved. Since the cleaning wheel 3 rotates against the rod 4, the cleaning groove 321 has a better cleaning effect on the rod 4. Cleaning groove 321 is when rotating along with cleaning wheel 3, can pass through the suction inlet of absorption passageway 53 for follow the clearance of pole material 4 surface and attached to the impurity of cleaning groove 321 in by absorption passageway 53 and walk, in order to guarantee the cleanliness of cleaning groove 321 itself, thereby show the effect that promotes pole material 4 surface cleaning. The filter screen 52 can block impurity, can make the impurity that is blockked drop to take-up (stock) pan 1 in by the collection through adsorbing opening 5121 on the cover 51 diapire simultaneously, and take-up (stock) pan 1 still can be collected the impurity that is directly cleared up from pole material 4 by cleaning wheel 3 simultaneously to guarantee the cleanliness that whole device used.
In order to facilitate the rotating shaft 33 of the cleaning wheel 3 to pass through the material receiving disc 1, a through hole is formed in the material receiving disc 1, and meanwhile, in order to prevent impurities in the material receiving disc 1 from falling out through the through hole, an upward extending enclosure wall 11 is formed in the through hole.
The inner wall of the cleaning groove 321 is provided with a brush 3211, and impurities on the surface of the rod material 4 can be effectively brushed off through the brush 3211.
The filter screen 52 is arranged in the adsorption channel 53 in an inclined state, that is, the upper side of the filter screen 52 is closer to the suction port of the adsorption channel 53 relative to the lower side of the filter screen, and in the structure, after impurities are blocked on the filter screen 52 under the adsorption action, because the filter screen 52 is inclined, the impurities can move downwards in an inclined manner, so that the impurities can fall into the material receiving tray 1 through the opening 5121.
In order to facilitate replacement or cleaning of the filter net 52, the upper panel 511 of the suction hood 51 is fixed to the bottom wall of the lower housing 512 of the suction hood 51 by bolts 513, and the lower housing 513 of the suction hood 51 is provided with slots 5122 into which the bottom surface of the filter net 52 is inserted. Under this structure, through dismouting bolt 513 alright realize the dismouting of top panel 511 to the convenience of impurity adsorption component use has been shown to be promoted in taking out or packing into of filter screen 52 of being convenient for.
The impurity adsorbing assembly 5 further comprises a retaining ring 55, the retaining ring 55 is fixed in the adsorbing channel 53 through a support rod 56, the lower end of the support rod 56 is formed on the bottom wall of the adsorbing cover 51, the retaining ring 55 is a semi-ring, two ends of the retaining ring 55 are formed on the support ring 56, and simultaneously, the semi-ring body of the retaining ring 55 extends into the cleaning groove 321 through the suction port of the adsorbing channel 53. Under this structure, when the clearance groove 321 passes through the suction port of the adsorption passage 53, the brush 3211 in the clearance groove 321 can collide with the stopper ring 55, so that the brush 3211 swings, and impurities attached to the brush 3211 are separated from the brush 3211, thereby being conveniently adsorbed by the adsorption passage 53.
The cleaning wheel 3 comprises an inner ring 31 and an outer ring 32, the outer ring 32 is coaxially sleeved on the inner ring 31, and the cleaning groove 321 is positioned on the outer ring 32. Have on the lower extreme endwall of inner ring 31 and keep off wall 311, have on the upper end endwall of outer ring 32 and keep off wall 322, during the assembly, embolia inner ring 31 with outer ring 32 from last to down on, make the through-hole on outer ring 32 keeps off wall 322 and the screw hole butt joint on the inner ring 31 upper end wall simultaneously, penetrate bolt 38 alright realize being connected between the two, simple structure, easy dismounting, the change of the outer ring 32 of being convenient for.
