Technical field
It the utility model is related to silicon carbide micro-powder production equipment technology, and in particular to adjust in a kind of double-roll crusher gap
Complete machine structure.
Background technology
Carborundum（SiC）Also known as diamond dust is with quartz sand, petroleum coke（Or coal tar）, wood chip（When producing green silicon carbide
Need to add salt）Formed Deng raw material by resistance furnace pyrolytic semlting.There is also rare mineral, Mo Sang in the Nature for carborundum
Stone.Carborundum is also known as moissanite.In the non-oxidized substance high-tech refractory raw material such as contemporary C, N, B, carborundum is most widely used
General, most economical one kind, it is properly termed as corundum or fire sand.The carborundum of Chinese industrial production at present is divided into black silicon carbide
Two kinds of silicon and green silicon carbide, it is hexagonal, proportion is 3.20~3.25, and microhardness is 2840~3320kg/mm2.
At present, one of capital equipment that double-roll crusher produces as silicon carbide micro-powder, in abrasive material production, roller skin is controlled
Uniform wear, be improve twin rollers production efficiency an important measure, and the gap of the roller skin of twin rollers two adjustment be control
One important step of roller skin uniform wear processed, traditional double-roll crusher is when carrying out gap adjustment, typically by artificially sentencing
Disconnected mode carries out both sides adjustment, and precision is very low, although market also occurs adjusting gap by hydraulic regulation mode
Double-roll crusher, but cost is higher, is transformed above existing equipment, it is also desirable to puts into certain fund.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of double-roll crusher clearance adjustment mechanism, the utility model
Existing double-roll crusher is efficiently solved in two pairs of rollers gap adjustment, according to artificial regulation, then precision is poor, if carrying out hydraulic pressure
Transformation, then cost and the problem of costly later maintenance.
The utility model is achieved through the following technical solutions：
A kind of double-roll crusher clearance adjustment mechanism, including fixed roll（1）, dynamic roller（2）, fixed roll（1）, dynamic roller（2）Lead to respectively
Cross fixed roller bearing seat（10）, action roller shaft bearing（7）It is connected with frame body, it is characterised in that：It is also symmetrical in the frame body
Clearance adjustment mechanism is provided with, the clearance adjustment mechanism includes dynamic roller pressing device, slack adjuster, moves roller pressing device
Including adjusting screw rod（11）, adjusting screw rod（11）On be cased with compression spring（9）, compression spring（9）One end and action roller shaft bearing（7）
Elastic connection, opposite end and adjusting nut（12）Adjustable connection, slack adjuster are located at fixed roller bearing seat（10）, action roller shaft holds
Seat（7）Between frame body on.
The further Technological improvement plan of the utility model is：
The slack adjuster includes rack mounting seat（6）, rack mounting seat（6）Top is engaged with adjusting gear rack（5）,
Adjusting gear rack（5）With rack mounting seat（6）Between be provided with standing screw（13）, standing screw（13）On be provided with clamping nut
（3）.
The further Technological improvement plan of the utility model is：
The clamping nut（3）With adjusting gear rack（5）Gland is provided between upper surface（4）.
The further Technological improvement plan of the utility model is：
The gland（4）It is made by elastomeric material or by nylon material.
The further Technological improvement plan of the utility model is：
The adjusting gear rack（5）It is overall L-shaped, including lateral part（51）, vertical section（52）, vertical section（52）With
Action roller shaft bearing（7）Between form interstitial site（8）.
The utility model compared with prior art, has following obvious advantage：
First, this it is new by the way of dynamic roller pressing device, slack adjuster are engaged in fixed roller bearing seat, action roller shaft
In the frame of bearing both sides respectively symmetrically, fixed roll is realized by the interstitial site of adjusting gear rack vertical section and action roller shaft bearing
Gap adjustment precision between dynamic roller, not only cost is low, without dismantling existing equipment, need to only unscrew tight nut, rack 5 is just
It is readily moved to the position needed.
2nd, the gland set between the utility model clamping nut and adjusting gear rack upper surface uses rubber or nylon material
Material is made, and because double-roll crusher has certain vibration in the course of work, and uses gland made of above-mentioned material can guarantee that
Adjusting gear rack and the positive engagement degree of rack mounting seat.
Brief description of the drawings
Fig. 1 is main structure diagram of the present utility model；
Fig. 2 is overlooking the structure diagram of the present utility model.
Embodiment
As shown in Figure 1, 2, the utility model includes fixed roll 1, dynamic roller 2, and fixed roll 1, dynamic roller 2 pass through fixed roller bearing seat respectively
10th, action roller shaft bearing 7 is connected with frame body, and clearance adjustment mechanism, the gap are also symmetrically arranged with the frame body
Adjustment mechanism includes dynamic roller pressing device, slack adjuster, and dynamic roller pressing device includes adjusting screw rod 11, on adjusting screw rod 11
Compression spring 9, the one end of compression spring 9 and the elastic connection of action roller shaft bearing 7, opposite end and 12 adjustable connection of adjusting nut are cased with,
Slack adjuster is in the frame body between fixed roller bearing seat 10, action roller shaft bearing 7.The slack adjuster includes
Rack mounting seat 6, the top of rack mounting seat 6 are engaged with adjusting gear rack 5, are provided between adjusting gear rack 5 and rack mounting seat 6 solid
Determine screw rod 13, clamping nut 3 is provided with standing screw 13.It is provided between clamping nut 3 and adjusting gear rack 5 upper surface
Gland 4.The gland 4 is made by elastomeric material or by nylon material.
The adjusting gear rack 5 is overall L-shaped, including lateral part 51, vertical section 52, vertical section 52 are held with action roller shaft
Interstitial site 8 is formed between seat 7.
Illustrate the course of work of the present utility model below in conjunction with the accompanying drawings.
By tightening the adjusting nut 12 of the side of compression spring 9 on adjusting screw rod 11, the fixed roll 1 of double-roll crusher is with moving
Roller 2 is closely packed together.Then the vertical section 52 of rack 5 is reserved into certain gap 8 with action roller shaft bearing 7 to place, then
Tightening nuts 3, rack 5 is fixed on rack seat 6 by gland 4.Due to being by mutually stinging between rack 5 and rack seat 6
What the tooth of conjunction was fixed, so very firm.With the abrasion of two roller skins, interval 8 is less and less, until the vertical section 52 of rack 5
It is close to action roller shaft bearing 7.When the gap at twin rollers both ends is all without can reset gap again.As long as two side ends are pre-
Every time, the abrasion of roller skin must be uniform to the interval stayed, and the utility model frame body is provides, itself and each part
Annexation be all prior art.
Technological means disclosed in the utility model is not limited only to the technological means disclosed in above-mentioned embodiment, also
Including being combined formed technical scheme by above technical characteristic.It should be pointed out that the ordinary skill for the art
For personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these are improved and profit
