Description
Technical field
The utility model relates to the equipment of the screening pelletizing green-ball in a kind of pelletizing production process, the roller type sieving machine that particularly a kind of gap conveniently is adjusted.
Background technology
In the production of metallurgical briquetting, essential guarantee green-ball quality.The pelletizing that needs to make sieves, and satisfactory green-ball just can carry out roasting, and adopting roller type sieving machine is exactly for reaching above-mentioned purpose.Two kinds of screening machine forms of main at present employing, a kind of is to adopt gear drive between each roller, and indirect gear is installed between two rollers, and the sieve roller can both equidirectionally be turned round.The roll screen gap of this form is non-adjustable, and after use a period of time, the wearing and tearing of sieve roller cause the gap of roll screen to become big, and qualified green-ball is also sifted out, and have reduced output, have improved cost.Another kind is to adopt traditional moving form of sieve roller patrilineal line of descent with only one son in each generation, opens inverted T-slot on the support under the sieve roll bearing seat, and bolt hangs in the T-slot slidably, after the gap of sieve roller is adjusted, will sieve roll bearing seat and fix with hanging over bolt on the T-slot.The adjustable gaps of this form is whole, still, has been crowded with material in the T-slot, adjusts very inconvenience in the production of pelletizing, and the stability and the precision of adjusted roll screen are very poor, bring bigger difficulty to repair and maintenance.
Utility model patent ZL03200388.9 " clearance adjustable type roll screen device " includes at least two sieve rollers that are arranged in parallel, transmission device, supporting seat, support, bearing block, one end of sieve roller is connected with transmission device on the supporting seat by Flexible Connector, supporting seat and bearing block tighten together, and the transmission mechanism that adjacent two sieve roll end connect is incorgruous installation.These features all are routine techniques basically, do not provide any adjusting device and method, just can adjust.
Summary of the invention
The purpose of this utility model provides the roller type sieving machine that a kind of gap conveniently is adjusted, can be very convenient, accurately the gap of roll screen is adjusted.
The purpose of this utility model realizes by following technical proposals:
Roller type sieving machine according to gap conveniently adjustment of the present utility model, comprise at least two board joints, support, it is characterized in that described driving shaft bearing and transmission device are by being bolted on the gusset piece, gusset piece is connected with support by being slidingly connected bolt, described being slidingly connected is with sliding shoe and circle cover on the bolt, this sliding shoe is contained in to do in the chute of support and with support and is slidingly matched, circle cover upper surface and machine seat board lower surface are sliding-contact, the circle cover that the propulsive mechanism of an adjusting play is slidingly connected on the bolt therewith is connected, and a position-limit mechanism is connected with described active bearings.
Described propulsive mechanism is by a rotating circular disk, be connected this rotating circular disk center, different leading screw about the rotation direction of two ends, the pushnut of the different rotation direction screw threads of the band of the threaded engagement at leading screw two ends therewith, the preceding push rod and the back stay that are hinged of pushnut therewith, the push rod other end is hinged on the described circle that is slidingly connected on the bolt and puts before this, and the fixed axis that is hinged of the other end of back stay is formed therewith.
Described position-limit mechanism is located at the leading screw that holds out against at bearing block two ends by the spacing pressing plate that is fixed by bolts on the driving shaft bearing, and the adjusting pad that is located between the bearing block is formed.
Slotted hole on described gusset piece and the support is and is slidingly matched.
The utility model thoroughly changes traditional type of attachment, transmission speed reducer and sieve roll bearing seat are fixed on the same gusset piece, can move between gusset piece and the support, when adjusting sieve roller gap, as long as rotate rotating circular disk, the distance of two forward blocks can become near, and push rod promotes two and is slidingly connected bolt and moves on the chute on the support simultaneously before making, and gusset piece is moved along the chute on the support.After inserting adjusting pad between driving shaft bearing and the driven axle bearing, rotate the gap adjustment that rotating circular disk has just been realized the sieve roller.
The utility model has solved in the past T-slot and has filled material, can't transfer bearing block and adjust after will be again to the shortcoming of shaft coupling centering.The adjustment of the roller type sieving machine that gap conveniently of the present utility model is adjusted, workload with adjustment is few, the time is short, the gap is adjusted accurately, need not be to the advantage of the shaft coupling centering of transmission, improve the operating efficiency of pelletizing production, reduce the cost of pelletizing production, reduced the workload of repair and maintenance.

The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.
As Fig. 1, shown in Figure 2, the roller type sieving machine that the utility model gap conveniently is adjusted, comprise at least two sieve rollers 4 that are arranged in parallel, sieve roller transmission device 1, shaft coupling 2, driving shaft bearing 3, driven axle bearing 5, gusset piece 7, support 6, it is characterized in that described driving shaft bearing 3 and transmission device 1 are fixed on the gusset piece 7 by bolt 8, gusset piece 7 is connected with support 6 by being slidingly connected bolt 9, described being slidingly connected is with sliding shoe 10 and circle cover 11 on the bolt 9, this sliding shoe 10 is contained in to do in the chute 15 of support 6 and with support 6 and is slidingly matched, circle cover 11 upper surfaces and machine seat board lower surface are sliding-contact, the circle cover 11 that the propulsive mechanism of an adjusting play is slidingly connected on the bolt 9 therewith is connected, and a position-limit mechanism is connected with described driving shaft bearing.
As shown in Figure 3, described propulsive mechanism is by a rotating circular disk 14, be connected these rotating circular disk 14 centers, different leading screw 13 about the rotation direction of two ends, the pushnut 12 of the different rotation direction screw threads of the band of the threaded engagement at leading screw 13 two ends therewith, the preceding push rod 17 and the back stay 18 that are hinged of pushnut 12 therewith, push rod 17 other ends are hinged on the described circle cover 11 that is slidingly connected on the bolt 9 before this, and the fixed axis 19 that is hinged of the other end of back stay 18 is formed therewith.Label 16 among the figure is a slide bolt, and this slide bolt can slide in the chute on the support 6 20.
As shown in Figure 4, described position-limit mechanism is by the spacing pressing plate 22 that is fixed by bolts on the driving shaft bearing 3, and what be located at the bearing block two ends holds out against leading screw 23, and the adjusting pad 21 that is located between the bearing block is formed.
As shown in Figure 2, described gusset piece 7 is with slotted hole on the support 6 and is slidingly matched.
When the adjusting play, unclamp and hold out against leading screw, rotate rotating circular disk, distance between the different forward block of the hand of spiral of this moment on the leading screw will become near, making preceding push rod promote to be slidingly connected bolt slides in the chute of support, thereby the distance between the change bearing block fixes bearing block with stopping means again, finishes adjustment work.Compared with prior art, adjustment work is simple, accurate, effective, can significantly shorten the repair time, improves utilization rate of equipment and installations, reduces production costs.
