Description
Technical field
The present invention relates to pellet sieving and Strand Feeding Technique field, but the roll-type distributing device in a kind of automatic adjusting roller crack particularly.
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, mainly by the sieve roller 3 of a plurality of parallel arrangements, reducing motor 1 and frame 2 form the roll-type distributing device.Equidistantly arrange between the sieve roller, the gap between the sieve roller has determined the size of the nodulizing that screening falls, so uniformly allotment sieve roller gap effect is particularly important.In traditional roll-type distributing device roll gap be designed to fixed value, can only rely on long screw manually to realize when mounted fine setting.But in production process, the gap of sieve roller can only redesign in the time of need to adjusting and make the roll-type distributing device, not only affects operating efficiency, and has caused the great wasting of resources.
Summary of the invention
But the invention provides the roll-type distributing device in a kind of compact conformation, the precisely reliable automatic adjusting roller crack of gap adjustment.
The objective of the invention is to realize by following technical proposals:
But the roll-type distributing device in automatic adjusting roller of the present invention crack, comprise frame, be located on this frame one group sieve roller reducing motor, respectively therewith one group of sieve roller reducing motor one group of sieve roller being connected and be arrangeding in parallel, the sieve roll bearing seat that is located at these sieve roller two ends, it is characterized in that upper surface, sieve in described frame are provided with slideway below the roll bearing seat, this slideway and described sieve roll bearing seat are done and are slidingly connected, and the end of described sieve roll bearing seat is connected with roller clearance adjusting device.
Described roller clearance 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 described splined shaft, one group of one group of gear nut that gear is meshed therewith respectively, one group of screw rod being meshed of the internal thread of one group of gear nut therewith respectively, one end is connected with described sieve roll bearing seat, the other end is provided with a pack support of axis hole, one end fixes with described screw rod and is 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 described pack support and therewith axis hole do and be slidingly connected.
But the characteristics of the roll-type distributing device in automatic adjusting roller of the present invention crack are:
Adopt the special construction of gear nut, both realized and the engaged transmission of gear, realize again the transmission 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 by connecting rod then.Because splined shaft drives simultaneously one group of gear and rotates, sieve roll bearing seat by sieving roller with gear meshed gears nut, 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 altogether displacement is (n-1) d, so the spacing of sieve roller can realize the automatic uniform adjusting by roller clearance adjusting device.
Compact conformation of the present invention, easy to operate, save time, laborsaving, the gap adjustment is precisely reliable, and is with low cost, 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 structural representation of the present invention.
Fig. 3 is the A-A cutaway view of Fig. 2.
The specific embodiment
Such as Fig. 2, shown in Figure 3, but the roll-type distributing device in automatic adjusting roller of the present invention crack, comprise frame 2, be located on this frame 2 one group sieve roller reducing motor 1, respectively therewith one group of sieve roller reducing motor 1 one group of sieve roller 3 being connected and be arrangeding in parallel, the sieve roll bearing seat 10 that is located at these sieve roller two ends, it is characterized in that upper surface, sieve in described frame 2 are provided with slideway 9 below the roll bearing seat 10, this slideway 9 is done with described sieve roll bearing seat 10 and is slidingly connected, and the end of described sieve roll bearing seat 10 is connected with roller clearance adjusting device.
Described roller clearance adjusting device comprises motor, the splined shaft 8 that is connected of motor therewith, be 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 described 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 again the transmission with screw rod 6.The pack support 4 that one end is connected with described sieve roll bearing seat 10, the other end is provided with axis hole, one end fix with described 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 described pack support 4 and therewith axis hole do and be slidingly connected.Because splined shaft 8 drives simultaneously one group of gear 7 and rotates, sieve roll bearing seat by sieving roller with gear meshed gears nut 5, with after the screw rod 6 of gear nut 5 engagement and the connecting rod 12 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 altogether displacement is (n-1) d, so the spacing of sieve roller can realize the automatic uniform adjusting by roller clearance adjusting device.
But the operation principle of the roll-type distributing device in automatic adjusting roller of the present invention crack is:
When needs are regulated the gap of sieve roller, starter motor drives splined shaft and rotates, driving simultaneously one group of gear rotates, each gear all is meshed with the external tooth of gear nut, gear nut drives screw rod by the engagement with screw rod again and does rectilinear motion, the sieve roll bearing seat that promotes each the sieve roller after the sieve roll bearing seat of 1# sieve roller by connecting rod simultaneously is displacement d successively, the sieve roll bearing seat of final n sieve roller altogether displacement is (n-1) d, so the spacing of sieve roller can realize the automatic uniform adjusting by roller clearance adjusting device.
Compact conformation of the present invention, easy to operate, save time, laborsaving, the gap adjustment is precisely reliable, and is with low cost, improved the operating rate of roll-type distributing device.
