A kind of opener
Technical field
The utility model relates to a kind of being used for the cotton fiber bag is cut into the required sheet or the opener of cotton-shaped cotton fiber.
Background technology
As everyone knows, cotton fiber is a kind of important chemical material, long several millimeters of the cotton fiber after making with extra care; Be convenient transportation, cotton fiber manufacturing enterprise generally can be that a length is respectively tens centimetres the bale of cotton with the cotton fiber compacting, sells the user.When the user uses, must with opener with the bale of cotton resolve into length and width, thickness can be by that suitably control, required sheet or floccule, to go back raw cotton fiber.At present, a kind of opener commonly used is the drum-type opener, its structure mainly comprises: frame, frame is provided with conveyer belt, on frame, also be provided with bale of cotton posting, power set and opener device, power set are made of motor and reductor usually, bale of cotton posting is positioned at the discharge end of conveyer belt, the opener device comprises that is mainly opened a feed roller, open the rib that feed roller is provided with protrusion, open feed roller and be movably arranged in the frame by its jackshaft and drive rotation by power set.During use, under the effect of power set, conveyer belt ceaselessly turns round, the bale of cotton of need cutting is put on the belt, conveyer belt to the direction transportation of opening feed roller, is opened the bale of cotton feed roller and is done rotation at a high speed, when the bale of cotton when opening feed roller and contact, the rib of opening on the feed roller just cuts the bale of cotton, divides slabbing, floccule the bale of cotton.The shortcoming of the drum-type opener of said structure is: can produce a large amount of dust in working angles, and cotton piece is easily stuck with the cylinder that rotates, and causes deadlock, can not more effectively controls the size and the thickness of the cotton fiber behind the opener.
The utility model content
The opener that technical problem to be solved in the utility model provides and a kind ofly turns round steadily, the cotton fiber thing size after the cutting and thickness can not had a large amount of dust by suitably control, working angles.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: described opener, comprise: frame, frame is provided with conveyer belt, on frame, also be provided with bale of cotton posting, opener device and power set, bale of cotton posting is positioned at the discharge end of conveyer belt, described opener device comprises: be arranged on the cutterhead cover on the frame, be provided with cutterhead in the cutterhead cover, cutterhead is fixed on an end of power transmission shaft, power transmission shaft is movably arranged in the frame, and the other end of power transmission shaft is connected with power set by transmission mechanism, and cutting tip is fixed on the cutterhead.
The cutting direction of above-mentioned cutting tip is vertical mutually with the throughput direction of conveyer belt.
The concrete structure of above-mentioned cutterhead is: cutterhead is made up of intermediate housing, connection spoke and peripheral retainer plate, and intermediate housing is fixed on an end of power transmission shaft, connects spoke and is fixedly installed between intermediate housing and the peripheral retainer plate, and cutting tip is fixed on and connects on the spoke.
Described power set comprise and being arranged on the frame by electric motor driven reductor that described transmission mechanism comprises the drive sprocket that is installed on speed reducer output shaft and the power transmission shaft, and chain is arranged on the drive sprocket.
Also be provided with the cutting object outlet in the lower end of above-mentioned cutterhead cover.
The utility model has the advantages that: the shared area of described opener is less, and running steadily can effectively be controlled the size of cotton fiber thing behind the opener, and the Dust Capacity of generation is little, and output can be effectively controlled.

The specific embodiment
The utility model is described in further detail below in conjunction with above-mentioned accompanying drawing.
As Fig. 1, shown in Figure 2, opener described in the utility model comprises: frame 1, frame 1 is provided with conveyer belt 2, on frame 1, also be provided with bale of cotton posting 3, opener device and power set 9, power set 9 are made up of motor and reductor usually, bale of cotton posting 3 is positioned at the discharge end of conveyer belt 2, described opener device comprises: be arranged on the cutterhead cover 6 on the frame 1, be provided with cutterhead 7 in the cutterhead cover 6, also be provided with cutting object outlet 61 in the lower end of cutterhead cover 6, cutterhead 7 is fixed on an end of power transmission shaft 12, in the present embodiment, the concrete structure of described cutterhead 7 is: cutterhead 7 is by intermediate housing 73, connect spoke 72 and peripheral retainer plate 71 compositions, intermediate housing 73 is fixed on an end of power transmission shaft 12, connect spoke 72 and be fixedly installed between intermediate housing 73 and the peripheral retainer plate 71, cutting tip 8 is fixed on by set bolt 14 and connects on the spoke 72---and its structure is referring to shown in Figure 3.Power transmission shaft 12 is arranged on the frame 1 by rolling bearing units 4, the other end of power transmission shaft 12 by sprocket wheel, and driving chain 11 be connected with the output shaft 10 of reductor in the power set 9.In the present embodiment, the rotary cutting direction of described cutting tip 8 is vertical mutually with the throughput direction of conveyer belt 2.
The operation principle of the opener of said structure is: the bale of cotton 13 that will cut is placed on the conveyer belt 2, and conveyer belt 2 transports the bale of cotton 13 to the direction near cutting tip 8; Under the effect of power set 9, cutterhead 7 fast rotational, drive cutting tip 8 fast rotational, when the bale of cotton 13 enters bale of cotton posting 3 and contacts with cutting tip 8, atwirl cutting tip 8 just cuts the bale of cotton 13, the bale of cotton 13 is cut into sheet, floccule, that is: the bale of cotton 13 just has been cut slabbing, floccule in the proal while.The effect of bale of cotton posting 3 is the bale of cotton 13 can be positioned in working angles, prevents phenomenons such as it is subjected to displacement, beats, to guarantee steadily carrying out of cutwork; In the course of the work, just can control size, the thickness of cutting object easily by the movement velocity of control conveyer belt 2 and the bale of cotton 13 and cutting tip 8, the cutting object after the cutting finally exports 61 smooth dischargings from the cutting object of cutterhead cover 6 lower ends.In addition, with the rib of opening on the feed roller described in the background technology process that the bale of cotton cuts is compared, that 8 pairs of bale of cottons of atwirl cutting tip cut not only is quick more, steadily, can also significantly reduce the generation of dust and effectively control the output of cutting object.
