Description
Technical field
The utility model relates to pellet screening and cloth technical field, the particularly a kind of roll-type distributing device that can regulate roll gap automatically.
Background technology
The roll-type distributing device is in pelletizing production, is used for sieving pellet, improves the equipment of quality of green pellets.As shown in Figure 1, the roll-type distributing device mainly by the sieve roller 3 of a plurality of parallel arrangements, form with frame 2 by reducing motor 1.Equidistance is arranged between the sieve roller, and the gap between the sieve roller has determined the size of the nodulizing that screening falls, so allotment sieve roller gap effect uniformly is particularly important.In traditional roll-type distributing device roll gap be designed to fixed value, can only rely on that long screw is artificial when mounted realizes fine setting.But in production process, the gap of sieve roller can only manufacture and design the roll-type distributing device in the time of need adjusting again, not only influences operating efficiency, and has caused the great wasting of resources.
Summary of the invention
The utility model provides a kind of compact conformation, gap adjustment precisely can regulate the roll-type distributing device of roll gap reliably automatically.
The purpose of the utility model realizes through following technical proposals:
The roll-type distributing device that can regulate roll gap automatically of the utility model; Comprise frame, be located on this frame one group sieve roller reducing motor, one group of sieve roller reducing motor one group of sieve roller being connected and laterally arranging, the sieve roll bearing seat that is located at these sieve roller two ends therewith respectively; It is characterized in that upper surface, sieve in said frame are provided with slideway below the roll bearing seat; This slideway and said sieve roll bearing seat are done and are slidingly connected, and the end of said sieve roll bearing seat is connected with the roll gap adjusting device.
Said roll gap adjusting device comprises motor; The splined shaft that is connected of motor therewith; Be located at the splined shaft bearing block at these splined shaft two ends, be located at one group of gear on the said splined shaft, respectively one group of one group of gear nut that gear is meshed therewith; One group of screw rod being meshed of the internal thread of one group of gear nut therewith respectively; One end and the pack support that said sieve roll bearing seat is connected, the other end is provided with axis hole, an end fix with said screw rod be connected, one group of connecting rod that the other end and adjacent sieve roll bearing seat fix and be connected, described one group of screw rod pass respectively the axis hole of a said pack support and therewith axis hole do and be slidingly connected.
The characteristics of the roll-type distributing device that can regulate roll gap automatically of the utility model are:
Adopt the special construction of gear nut, both realized and the gear meshing transmission, realize transmission again with screw rod.When the driven by motor splined shaft rotates (establishing corner is θ), splined shaft driven gear and gear nut external toothing, the rotation of gear nut make screw rod generation rectilinear motion (establish distance and be d).Because the sieve roll bearing seat of 1# sieve roller is fixed on the slideway, first screw rod sieve roll bearing seat displacement d successively on slideway of promoting 2# sieve roller through connecting rod then.Because splined shaft drives one group of gear simultaneously and rotates; Sieve roll bearing seat through sieving roller with the gear nut of gears engaged, with after the screw rod of gear nut engagement and the connecting rod that is connected with screw rod make the sieve roll bearing seat of 1# sieve roller each is displacement d successively all; The sieve roll bearing seat of final n sieve roller displacement altogether is (n-1) d, so the spacing of sieve roller can realize automatic even regulation through the roll gap adjusting device.
The utility model compact conformation, easy to operate, save time, laborsaving, the gap adjustment is precisely reliable, with low cost, has improved the operating rate of roll-type distributing device.
Description of drawings
Fig. 1 is the structural representation of former roll-type distributing device.
Fig. 2 is the structural representation of the utility model.
Fig. 3 is the A-A cutaway view of Fig. 2.
The specific embodiment
Like Fig. 2, shown in Figure 3; The roll-type distributing device that can regulate roll gap automatically of the utility model; Comprise frame 2, be located on this frame 2 one group sieve roller reducing motor 1, one group of sieve roller reducing motor 1 one group of sieve roller 3 being connected and laterally arranging, the sieve roll bearing seat 10 that is located at these sieve roller two ends therewith respectively; It is characterized in that upper surface, sieve in said frame 2 are provided with slideway 9 below the roll bearing seat 10; This slideway 9 is done with said sieve roll bearing seat 10 and is slidingly connected, and the end of said sieve roll bearing seat 10 is connected with the roll gap adjusting device.
Said roll gap adjusting device comprises motor, and the splined shaft 8 that is connected of motor therewith is located at the splined shaft bearing block 11 at these splined shaft 8 two ends; Be located at one group of gear 7 on the said splined shaft 8; One group of one group of gear nut 5 that gear 7 is meshed therewith respectively, one group of screw rod 6 being meshed of the internal thread of one group of gear nut 5 therewith respectively utilizes the special construction of gear nut 5; Both realized and the engaged transmission of gear 7, realized transmission again with screw rod 6.The pack support 4 that one end is connected with said sieve roll bearing seat 10, the other end is provided with axis hole; One end fix with said screw rod 6 be connected, one group of connecting rod 12 that the other end and adjacent sieve roll bearing seat fix and be connected, described one group of screw rod 6 pass respectively the axis hole of a said pack support 4 and therewith axis hole do and be slidingly connected.Because splined shaft 8 drives one group of gear 7 simultaneously and rotates; Through with the gear nut 5 of gears engaged, with sieve roll bearing seat that the screw rod 6 and the connecting rod that is connected with screw rod 12 of gear nut 5 engagements make 1# sieve roller after the equal displacement d successively of each sieve roll bearing seat of sieving roller; The sieve roll bearing seat of final n sieve roller displacement altogether is (n-1) d, so the spacing of sieve roller can realize automatic even regulation through the roll gap adjusting device.
The operation principle of the roll-type distributing device that can regulate roll gap automatically of the utility model is:
When needs are regulated the gap of sieve roller; Starter motor drives splined shaft and rotates; Driving one group of gear simultaneously rotates; Each gear all is meshed with the external tooth of gear nut, and gear nut is done rectilinear motion through driving screw rod with the engagement of screw rod again, and the sieve roll bearing seat that promotes each the sieve roller after the sieve roll bearing seat of 1# sieve roller through connecting rod simultaneously is displacement d successively; The sieve roll bearing seat of final n sieve roller displacement altogether is (n-1) d, so the spacing of sieve roller can realize automatic even regulation through the roll gap adjusting device.
The utility model compact conformation, easy to operate, save time, laborsaving, the gap adjustment is precisely reliable, with low cost, has improved the operating rate of roll-type distributing device.
