Abstract

The utility model provides a cotton gin. The cotton gin solves the problems that an existing cotton gin needs people to control length and has low accuracy. The cotton gin comprises a cotton ginning gear used for processing steel wires and an air pression shear. The cotton gin further comprises a controller and a length inductor which has the same rotary shaft with the air pression shear. The length inductor outputs length measuring signals to the controller, and the controller outputs cutting signals to the air pressure shear according to the length measuring signals. Automatic control is achieved, cost is low, a length control device is controlled by pulse signals which are close to a switch, accuracy is high, and labor power is saved.

Description

A kind of cotton gin

Technical field

The utility model relates to mechanical field, particularly a kind of cotton gin.

Background technology

Existing medium-sized and small enterprises use cotton gin to only have an a pair of working gear of driven by motor, and Artificial Control length is manually cut short, and can not automatically determine length, and precision is low.

The utility model content

The utility model proposes a kind of cotton gin, having solved existing cotton gin needs Artificial Control length, problem that precision is low.

The technical solution of the utility model is achieved in that

A kind of cotton gin, comprise for cotton ginning gear and the air pressure of processing steel wire and cutting, also comprise controller and with the length inductor of described cotton ginning gear with rotating shaft, length inductor output linear measure longimetry signal is to described controller, described controller according to the linear measure longimetry signal output cut off signal and cut to described air pressure.

Alternatively, described length inductor comprises and the flabellum of described cotton ginning gear with rotating shaft, is provided with the approach switch of induction flabellum turned position in the flabellum radius of gyration, and the approach switch output pulse signal is to described controller.

Alternatively, described controller comprises: the counter of store the memory of length settings, described pulse signal being counted and numerical value in the memory sum counter compared and according to comparative result output cut off the comparator that signal is cut to air pressure.

Alternatively, described controller is single-chip microcomputer.

The beneficial effects of the utility model are: realized automatic control, cost is low, and length control device adopts the pulse signal control of approach switch, and precision is high, has saved manpower.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the structured flowchart of a kind of cotton gin of the utility model;

Fig. 2 is the structural representation of length inductor among Fig. 1.

The specific embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figure 1, cotton gin of the present utility model comprises that controller 10, length inductor 20, air pressure cuts 30 and cotton ginning gear 40.Cotton ginning gear 40 is used for steel wire is carried out process operation, and air pressure cuts 30 by drive motors driving cut-out steel wire.Length inductor 20 and the 40 same rotating shafts of cotton ginning gear, the rotation distance of cotton ginning gear 40 is identical with steel wire length, therefore the accurate length of measuring steel wire of length inductor 20, and output linear measure longimetry signal is to controller 10, store the moulding length of first steel wire in the controller 10, when moulding length that the linear measure longimetry signal equals to store, output is cut off signal and is cut 30 to air pressure, and air pressure is cut 30 and cut off steel wire.Cotton gin of the present utility model also is provided with speed regulator, adjustable machine rotating speed.

Fig. 2 is the structural representation of length inductor among Fig. 1.As shown in Figure 2, length inductor 20 comprises: with the flabellum 201 of cotton ginning gear 40 with rotating shaft, be provided with the approach switch 202 of induction flabellum turned position in flabellum 201 radiuses of gyration, when flabellum 201 skims over from approach switch 202 the place aheads, approach switch 202 output pulse signals are to controller, and the quantity of pulse signal is directly proportional with steel wire length.

Again as shown in Figure 1, controller 10 comprises: counter 101 is used for the pulse signal of approach switch output is carried out counting operation; Memory 102 stores the pulse count signal value of first steel wire shaping; Comparator 103 compares the numerical value in memory 102 sum counters 101, and cuts off signal according to comparative result output and cut 30 to air pressure, for example when the numerical value in the counter 101 equals numerical value in the memory 102, exports and cuts off signal.Numerical value in the memory 102 can arrange according to the length of steel wire to be processed, as long as store the moulding length of first steel wire, and the continuous processing steel wire of just can automatic shearing having no progeny.Cotton gin of the present utility model, controller 10 can be single-chip microcomputer, also can be DSP, FPGA or arm processor.

Cotton gin of the present utility model has been realized automatic control, and cost is low, and length control device adopts the pulse signal control of approach switch, and precision is high, has saved manpower.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
