The material baffle for three-roller grinding machine self-checking device
The utility model relates to the three-roll grinder technical field, especially a kind of material baffle for three-roller grinding machine self-checking device.
Material baffle for three-roller grinding machine is a kind ofly in process of production material to be blocked for three-roll grinder, prevent the device that material outwards flows out from abrasive areas, it is the indispensable device of three-roll grinder, if this device work is undesired, the significant wastage that will cause grinding material, economic loss, the material of loss is also to environment.The normal method that adopts manual set bolt or hydraulic mandril to contact with roller of traditional material baffle, adopt manual set bolt fixed dam, in long-time use procedure, it is local easy to wear that baffle plate contacts with roller, wear and tear rear because baffle plate and frame are fixed, so produce unsettled phenomenon between meeting and the roller, and then cause leaking the material situation, need to re-start the contact-making surface of reconditioning baffle plate and adjustment and roller, reconditioning needs certain knack with this baffle plate of adjustment, thereby relatively high on human cost; And adopt hydraulic mandril to withstand the method for baffle plate, and because baffle plate need to make by constant hydraulic pressure baffle plate contact with roller, mechanism is complicated, needs equipment to carry hydraulic power source, cost is relatively costly.
The utility model content
The technical problems to be solved in the utility model is: in order to solve the technical problem that the material baffle adjustment is difficult in the prior art, device is complicated, provide a kind of simple in structure, the material baffle for three-roller grinding machine self-checking device of long service life.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of material baffle for three-roller grinding machine self-checking device, be installed on the both sides frame of three-roll grinder, comprise holder, material baffle, fixed bar and be used for the spring of pulling fixed bar, described holder is installed in the frame, have the first chute of vertical setting on the holder, have the second chute of vertical setting on the described frame outer wall, one end of described fixed bar is arranged in the first chute, the fixed bar other end passes the second chute and is fixedly connected with material baffle, described material baffle bottom surface is connected with the roller contact of three-roll grinder, described spring one end is fixed on the frame inner wall of fixed bar below, and the spring other end is fixedly connected with the fixed bar middle part.
A kind of embodiment, the plate face middle part of described material baffle has installation shaft, and the end face of the fixed bar part outside frame has installing hole, and the installation shaft of described material baffle is inserted in the installing hole.
Another kind of embodiment, the plate face middle part of described material baffle has jack, and the jack of described fixed bar and material baffle is slidingly matched.
In order to be convenient to moving up and down of fixed bar, being convenient to material baffle contacts with roller is seamless, the slide up and down distance of described fixed bar in holder the first chute is 0.5mm ~ 3mm, the slide up and down distance of described fixed bar in the second chute is 1mm ~ 20mm, and the transverse shifting distance of described fixed bar between the first chute and the second chute is 0mm ~ 5mm.
The beneficial effects of the utility model are, material baffle for three-roller grinding machine self-checking device of the present utility model is simple in structure, pulling force by spring, fixed bar is spurred downwards, thereby material baffle also pulling is downwards contacted with roller, the pressure of contact can be regulated by the pulling force of spring, when material baffle weares and teares, because the pulling force of spring exists all the time, thereby can make material baffle a constant pressure-acting be arranged at roller surface, thereby has reached permanent instructions for use.

The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Embodiment 1, as shown in Figure 1, comprise holder 2, material baffle 3, fixed bar 4 and be used for the spring 5 of pulling fixed bar 4, holder 2 is installed in the frame 1, have the first chute 21 of vertical setting on the holder 2, have the second chute 11 of vertical setting on frame 1 outer wall, one end of fixed bar 4 is arranged in the first chute 21, the plate face middle part of material baffle 3 has installation shaft 31, the end face of fixed bar 4 parts outside frame 1 has installing hole 41, fixed bar 4 other ends pass the second chute 11 and peg graft by installing hole 41 with the installation shaft 31 of material baffle 3, material baffle 3 bottom surfaces are connected with roller 6 contacts of three-roll grinder, spring 5 one ends are bolted on frame 1 inwall of fixed bar 4 belows, and spring 5 other ends are fixedly connected with fixed bar 4 middle parts.By selecting suitable spring 5, the pressure that can 5N ~ 500N is provided for material baffle 3 adapts to various materials and grinds in the utility model, and this spring 5 can be selected other metal and nonmetallic elastic device.
The slide up and down distance of fixed bar 4 in holder 2 first chutes 21 is 2mm, and the slide up and down distance of fixed bar 4 in the second chute 11 is 10mm, and the transverse shifting distance of fixed bar 4 between the first chute 21 and the second chute 11 is 2mm.
As shown in Figure 2, embodiment 2 is with the difference of embodiment 1, has jack 32 in the middle part of the plate face of material baffle 3, and fixed bar 4 is slidingly matched with the jack 32 of material baffle 3, and other repeat no more with embodiment 1 herein.
The utility model is by the pulling force of spring 5, fixed bar 4 is spurred downwards, thereby material baffle 3 also pulling is downwards contacted with roller 6, the pressure of contact can be regulated by the pulling force of spring 5, when material baffle 3 wearing and tearing, because the pulling force of spring 5 exists all the time, thereby can make material baffle 3 a constant pressure-acting be arranged on roller 6 surfaces, thereby has reached permanent instructions for use.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
