Description

A kind of jar mill

Technical field

The utility model relates to powder milling apparatus field more particularly to jar mill fields.

Background technique

Jar mill is laboratory, the extra-fine grinding of small lot production, mixing apparatus.The machine is easy to operate, ground and mixed It uniformly, is the splendid equipment of scientific research, test, production.It can be widely applied to electronic material, magnetic material, biological medicine, nonmetallic The industries such as mine, new material.

At work, the intracorporal abrasive media of cylinder and material are promoted to certain altitude with barrel body rotation together to jar mill, by It is detached from barrel in gravity to fall along parabola, material is in the percussion of abrasive media and the rolling of abrasive media and cunning It is crushed under movable property raw friction and shear action, mixing.

Usually every layer of traditional jar mill has an active, two driven totally three axis, and driving shaft is in intermediate, driven shaft two Side, driving shaft are driven by transmission device and are rotated, and then successively drive grinding pot, driven shaft to rotate together by frictional force, this The class jar mill grinding pot big to weight and material have preferable crushing, mixed effect.

But when the total weight of material in grinding pot and tank is smaller, driving shaft can only drive grinding in front of direction of rotation Grinding jar normal rotation, and for the grinding pot at spindle rotation direction rear, before revolving speed is significantly lower than spindle rotation direction The grinding pot of side.

Utility model content

For the problems of above-mentioned, the technical problem to be solved by the utility model is to by the improvement in structure, When so that the total weight of jar mill material in grinding pot and tank is smaller, moreover it is possible to keep the grinding pot revolving speed one of driving shaft two sides It causes.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of jar mill, including at least one layer of work Make platform, on workbench side by side and interval installation there are three rubber rollers, the both ends of each rubber roller pass through bearing and are installed on rubber roller mounting rack On, wherein it is located in the middle the first rubber roller and rotation is driven by motor, the second rubber roller positioned at two sides respectively passes through a driving member conduct Connection keeps linking with the first rubber roller.

Further, the driving member is transmission belt, and the both ends of transmission belt are placed on belt wheel, belt wheel then housing and solid Due on the rubber roller.

Further, the transmission belt is connected to the position on each rubber roller, is located substantially at the middle part of rubber roller.

Further, the link position of two transmission belts and the first rubber roller mutually maintains spacing.

The beneficial effects of the utility model are: (1) passes through biography while the first rubber roller (driving shaft i.e. above-mentioned) rotates Dynamic band drives the second rubber roller (driven shaft i.e. above-mentioned) rotation, so as to avoid the total weight of material in grinding pot and tank smaller When, the inconsistent problem of the grinding pot revolving speed of the first rubber roller two sides；(2) in some cases, the utility model even can not Using the grinding pot of profession, directly small lot materials can be crushed, be mixed using common plastics bottle.

Detailed description of the invention

Fig. 1 is the main view of the utility model；

Fig. 2 is the top view of Fig. 1；

In the figure, it is marked as 1- workbench, 2- rubber roller, 3- rubber roller mounting rack, 4- transmission belt, the first rubber roller of 21-, 22- second Rubber roller.

Specific embodiment

The utility model is described in further detail combined with specific embodiments below, but the embodiment party of the utility model Formula is without being limited thereto.

As depicted in figs. 1 and 2, a kind of jar mill of the utility model comprising at least one layer of workbench 1, on workbench 1 Side by side and it is spaced rubber roller 2 there are three installations, the both ends of each rubber roller 2 pass through bearing (not marking in figure) and are installed on rubber roller mounting rack On 3, wherein be located in the middle the first rubber roller 21 and rotation is driven by motor, the second rubber roller 22 positioned at two sides respectively passes through a transmission Part keeps linking as connection with the first rubber roller 21.

In a kind of embodiment of the utility model, the driving member is transmission belt 4, and the both ends of the transmission belt 4 are equal It is placed on belt wheel (not marked in figure), belt wheel then housing and is fixed on the rubber roller 2.It is shown in Figure 2, belt wheel four A, two of them are located on the first rubber roller 21, other two is located on two the second rubber rollers 22, four belt wheels substantially position Spacing, the direction of transmission belt 4 and the axis of rubber roller 2 are maintained between two belt wheels on the middle part of rubber roller 2, the first rubber roller 21 Direction keeps vertical.The purpose that belt wheel is located at 2 middle part of rubber roller is, guarantees uniform force, so that being driven relatively stable property.

In some embodiments, other mechanical structures or component, such as gear assembly can also be used in driving member.

When the utility model is run, after the first rubber roller 21 is driven by a motor, two sides can be driven respectively by two transmission belts 4 The second rubber roller 22 it is driven, so as to avoid following problem existing in the prior art: when in grinding pot and tank material it is total When weight is smaller, because the second rubber roller 22 cannot be rotated synchronously with the first rubber roller 21, the first rubber roller 21 is caused to be only capable of driving its rotation Grinding pot in front of direction normally rotates, and the grinding pot for being unable to drive its rear normally rotates, and there are revolving speeds for two grinding pots Difference, the slower problem of rear grinding pot revolving speed.

By adding driving member two the second rubber rollers 22 are rotated synchronously with the first rubber roller 21, thus, even if In grinding pot and tank in the lesser situation of the total weight of material, two grinding pots of 21 two sides of the first rubber roller are also able to maintain revolving speed phase Together, and no matter rotate forward or invert, the problem inconsistent because of two grinding pot revolving speeds can be avoided, even, in some cases Under, the utility model can also without using profession grinding pot, directly using common plastic bottle can to small lot materials into Row is crushed, is mixed.

It effectively prevents when total weight is smaller, grinding pot can only be placed in side and be rotated, the other side can only be vacant The case where.The utility model two sides can place grinding pot, working efficiency can be effectively improved to original twice.In addition, When design, for the diameter for adapting to grinding pot, the distance between the first rubber roller 21 and the second rubber roller 22 be can change, and correspondingly, be passed The length of dynamic band can also be adaptively adjusted.
