Description

The multiple stage pressure roller

Technical field

The utility model relates to a kind of multiple stage pressure roller, and particularly a kind of pressure roller of adjusting plectrum and producing multiple stage platen pressure of stirring is applicable to outdevices such as computing machine lettering machine or chopping machine.

Background technology

Fig. 1 shows the structure of traditional pressure roller 1, include a bearing 11, a cantilever 12 and a spring 13, wherein these cantilever 12 1 ends are provided with mechanism of

paper holding

121, and 11 of this bearings are hubbed at cantilever 12 tops, and spring 13 1 ends can be arranged in bearing 11, and end then is set around on the cantilever 12 in addition.Therefore by driving cantilever 12, stretching of spring 13 change the stressed of paper.

Because aforementioned structure in use, its roller 121 is made as by perseverance and presses down, and cause positioning inconvenient, so once designed a pressure roller before the applicant with positioning folder 124, as shown in Figure 2, an end of its cantilever 12 is provided with a positioning folder 124, when making its positioning, can temporarily roller 121 be promoted, make the convenient position (Taiwan announces the 315785th) that changes.

Yet, above-mentioned two kinds of traditional pressure rollers are on structure design, spring directly hung be located on the bearing, pressure roller can only produce mono-pressure during operation, though all can reach the demand in the operation, but desire is made more detailed manufacture or with used paper difference when adjusting suitable pressure, just have can't be obtained on its function, because when an equipment will be done exquisite output, its effect is just just like draw a picture on paper (or cutting), and the power of platen must be put gently, and the speed of describing of starting writing will slow down, just can draw or cut out very exquisite pattern, otherwise, if output speed is kept necessarily, but can do the multistage adjustment in the platen power, also difference to some extent of output quality under its each state, but with aforementioned two traditional structures, its effect all can't reach the demand of smart matter output.

Summary of the invention

Main purpose of the present utility model provides a kind of multiple stage pressure roller that various control pressure function can be arranged when platen.

For reaching the purpose of above-mentioned utility model, a kind of multiple stage pressure roller that the utility model is set comprises: a bearing, be erected on the track of outdevice, but the adjusting work position; One cantilever is hubbed at the bearing below, is the seesaw shape, and an end is provided with a roller; And at least one group of pressure adjustmenting mechanism, being provided between cantilever and the bearing, every group of pressure adjustmenting mechanism includes one and adjusts a plectrum and a spring, and mat is adjusted the adjustment of plectrum and is changed spring extension elastic force, makes the roller of cantilever one end press down the strength change.

For ease of more deep understanding being arranged, with instantiation the utility model is elaborated below in conjunction with accompanying drawing to the utility model.

The specific embodiment

See also Fig. 3, Fig. 4, an embodiment of the utility model multiple stage pressure roller 8 includes a bearing 3, a cantilever 2 and two groups of pressure adjustmenting mechanisms 4.Wherein this bearing 3 is erected on the track 9 of outdevice, but adjusting work position (as Figure 10); This cantilever 2 is hubbed at bearing 3 belows and is the seesaw shape, one end then is provided with a roller 21, and two groups of pressure adjustmenting mechanisms 4, be provided between cantilever 2 and the bearing 3, every group of pressure adjustmenting mechanism 4 includes one and adjusts a plectrum 41 and a spring 42, but mat is adjusted the adjustment of plectrum 41 and is changed spring 42 extension elastic force when making applied in any combination, makes the roller 21 of cantilever 2 one ends press down the strength change.

See also Fig. 4～Fig. 7, during enforcement, cantilever 2 end in addition is provided with a positioning folder 22, and bearing 3 is equipped with a lockhole 31 perpendicular to each correspondence of both sides of cantilever 2, in bearing 3, and make these T shape bar 7 bottoms cantilever 2 of can conflicting for a T shape bar 7 interlockings, this T shape bar 7 bodies of rod upper end then is provided with a torque spring 71, make clinching or pull open positioning folder 22 o'clock, drive T shape bar 7 to change the displacement of roller 21.And 3 bodies of this bearing are provided with a perforation 32 in addition, but when 8 of pressure rollers are on pressure roller track 9 adjusting work position (as shown in figure 10).

In addition, as shown in Figure 4, these two groups of pressure adjustmenting mechanisms 4 include one respectively and adjust a plectrum 41 and a spring 42, and these two groups of pressure adjustmenting mechanisms 4 are provided between cantilever 2 and the bearing 3.This adjustment plectrum 41 is the center, and to establish the rule of screw 415 tabular, and will adjust plectrum 41 interlockings on bearing 3 with a screw 5, and this adjustment plectrum 41 is provided with the catch 411 of prominent folding on one side, and edge break becomes to pull the portion of holding 412 in addition, hold and be provided with perforation 413 and breach 414 in addition in what pull the portion of holding 412, collude the position for spring 42, spring 42 hold the knot of hook then in addition on the axis 221 of positioning folder 22.

And utilize the utility model to be provided with two characteristics of adjusting plectrum 41, can stir two and adjust plectrums 41 in last, one on the other or time inferior position (as Fig. 8, shown in Figure 9), make when using pressure roller, stir the extension that adjustment plectrum 41 is adjusted spring 42 by pulling the portion of holding 412, thus, paper 6 because of adjusting the different mode of stirring of plectrum 41, just can be done more accurate more changeable cutting by the degree of roller 21 pressurizeds.

Therefore, the utility model has the advantage of to make originally only have the pressure of single pressure selection Paper is taken turns, and becomes to have three sections different pressures adjustment of heavy, medium and light, cuts in order to be fit to various difference Cut the requirement of quality, namely exerting oneself equally lower, if through the utility model improvement design with pressure roller After moderate pressure is turned down, then can make the cutting of carrying out more exquisite, reach and improve the cutting quality Practical purpose.
