Abstract
A grinding disc adjusting device for a grinder is mainly used for adjusting the space between two grinding discs of a grinder in quality detection of food and products for obtaining samples with different granularities. According to the grinding disc adjusting device in prior art, an adjusting handle and a base body are connected with each other through an external thread and an internal thread additionally machined on the adjusting handle and the base body; secondly, a compression spring and a spring retainer ring are additionally arranged on the cylindrical surface of the tail of a grinding disc base; besides, the back end surface of the adjusting handle is additionally provided with a zero adjusting screw and is assembled with a fastening screw. The grinding disc adjusting device has simple structure, convenient operation, can eliminate the thread clearance between the adjusting handle and the base body, guarantees the accurate adjustment of the grinding disc space, ensures the actual adjusted space between the grinding discs to be consistent with the display space in operation adjustment. Meanwhile, the actual space after each repeated adjustment is ensured to be the same, and samples with the same granularity can be obtained in each time.
Description
Affiliated technical field
The utility model relates to a kind of in grain and quality of item thereof detect, and is used for testing moisture content, pulverizes the mill adjusting device of the pulverizing grinding machine of sample.It is applicable to that equally also other need regulate the same category of device of mill spacing.
Background technology
At present, the mill of existing cereal pulverizer is regulated and put is by regulating being used of handle and mill adjusting screw(rod), to regulate the rectilinear motion that rotatablely moving of handle is converted into the mill adjusting screw(rod), thereby the mill that promotes to link to each other with the mill adjusting screw(rod) moves as straight line, realize adjusting the gap length between mill, finally reach the purpose of adjusting the sample thickness of milling.There is the gap all the time between the screw rod of this frame mode and nut, there is idle stroke during adjusting, make the actual distance distance shown of adjusting between mill have certain difference with operating adjusting, can not be accurate, so just can not get the sample of required fineness; In addition under same operation regulated quantity, the sample fineness of pulverizing out also can be because of the existence in gap, and often inconsistent, so just can not accomplish just and differentiate accurately the detection of sample.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, provides a kind of simple in structure, easy to operate, can eliminate and regulate thread pitch between handle and the mill adjusting screw(rod), can guarantee accurately to regulate the adjusting device of mill spacing.Thereby make the actual adjustment between mill identical, can guarantee the uniformity of each re-adjustments distance simultaneously, obtain the forward and backward all samples of unanimity of smashing fineness apart from the distance shown with operating adjusting.
The purpose of this utility model realizes by following technical measures: this mill adjusting device is to improve on the mill adjusting device basis of existing pulverizer, it also contains matrix, abrasive disk seat, mill, limited block, lock-screw, adjusting handle, gear alignment pin, locating pin spring, its innovation part is at first to have newly established internal thread on the adjusting handle, and the external screw thread that allows the adjusting handle newly establish by this internal thread and matrix afterbody cylindrical is connected with matrix; Next is newly to wear a compression spring and newly fix a check ring at the cylinder face of abrasive disk seat afterbody, allows an end face of this compression spring contact with the blind hole bottom surface of matrix tail end, and the other end of compression spring contacts with check ring; It three also is provided with zero adjusting screw in that the rear end face of regulating handle is newly-increased, and is furnished with the holding screw of this zero adjusting screw of locking.
Check ring in the utility model is a shaft block ring, or slim nut.
The utility model with the beneficial effect that existing mill adjusting device is compared is: this mill adjusting device is owing to added the compression spring, make the matching thread of regulating handle and matrix be in stress always, remain fixing engagement direction, thereby eliminated the idle stroke gap between being threaded.So just can guarantee the accuracy that the mill spacing is adjusted, making actual between mill adjust distance and operation, to regulate shown distance consistent, and the actual range that can guarantee each re-adjustments simultaneously is unanimity all, obtains all identical sample of each smashing fineness.This adjusting device is simple in structure simultaneously, and is easy to operate.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Among the figure: 1 mill, 2 matrixes, 3 abrasive disk seats, 4 locating pin springs, 5 gear alignment pins 6 are regulated handle 7 check rings 8 zero adjusting screws 9 compression springs 10 limited blocks 11 lock-screws 12 chutes 13 gear shrinkage pools 14 spouts 15 feeding-passages 16 holding screws
The specific embodiment
The utility model is described further below in conjunction with drawings and Examples: the basic structure of this mill adjusting device is identical with existing mill adjusting device also to be to be made of matrix 2, abrasive disk seat 3, mill 1, adjusting handle 6, locating pin spring 4, gear alignment pin 5, gear shrinkage pool 13, chute 12, limited block 10, spout 14, feeding-passage 15, different is to regulate the newly-increased internal thread that is provided with on the handle 6, meanwhile also increasing newly on the cylindrical of matrix 2 afterbodys and be provided with external screw thread.Regulating handle 6 is to follow matrix 2 to link together by its internal thread and the external screw thread on the matrix 2.Next is newly to wear a compression spring 9 and newly fix axle check ring 7 at the cylinder face of abrasive disk seat 3 afterbodys, and allowing an end face of compression spring 9 contact with the blind hole bottom surface of matrix 2 tail ends, the other end of compression spring 9 contacts with check ring 7 with axle.In addition also at the newly-increased zero adjusting screw 8 that is provided with of the rear end face of regulating handle 6, and this zero adjusting screw 8 is furnished with holding screw 16 to its locking.
This mill adjusting device is work like this: when needs dwindle the spacing of pulverizing between mill, only need the clockwise direction rotation to regulate handle, so regulate handle just the external screw thread spiral on the matrix afterbody cylindrical advance, the zero adjusting screw of regulating simultaneously on the handle rear end face also moves to the previous crops straight line together, because the cylinder rear end face of zero adjusting screw and abrasive disk seat afterbody is tightly contacted, thereby zero adjusting screw just promotes abrasive disk seat to move forward, and simultaneously the compression spring is compressed.Abrasive disk seat moves forward the spacing of just having dwindled between mill, can obtain the sample of required thickness.In this process, because the elastic force effect of compression spring, allow and regulate the reaction force that always is compressed spring between the screw thread that is connected between handle and matrix, remain folk prescription to engagement, eliminated the gap between screw thread, do not had idle stroke, so gear alignment pin and adjusting handle gear every the cooperation once of hole, zero adjusting screw just promotes the distance that abrasive disk seat moves a regulation exactly, so just pulverizes out the sample of required fineness.
When needs increase the spacing of pulverizing between mill, as long as handle is regulated in counter rotation, so the adjusting handle just drives zero adjusting screw and back moves, this moment, abrasive disk seat will back move with zero adjusting screw under the reaction force of compressed compression spring.Also remain former folk prescription between handle and the screw thread that matrix is connected and contact and regulate, do not have idle stroke to meshing.Gear alignment pin and regulate handle gear every the cooperation once of hole like this, the spacing between the mill just increases an adjustable range.
