Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
It should be noted that, in the present invention, the such as relational terms of first and second grades and so on is only used for an entity or operation to separate with another entity or operating space, and not necessarily requires or imply the relation that there is any this reality between these entities or operation or sequentially.And, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or terminal device and not only comprise those key elements, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or terminal device.When not more restrictions, the key element limited by statement " comprising ... " or " comprising ... ", and be not precluded within process, method, article or the terminal device comprising above-mentioned key element and also there is other key element.In addition, in this article, " be greater than ", " being less than ", " exceeding " etc. be interpreted as and do not comprise this number; " more than ", " below ", " within " etc. be interpreted as and comprise this number.
Embodiments provide a kind of granulator overload protection arrangement; wherein; shown in structural reference Fig. 1 of granulator; granulator has a main shaft be fixedly installed 1 and and is located at the rotor (ring mould 3 and hollow spindle 2 form rotor jointly) of main shaft by bearing holder (housing, cover); overload protection arrangement structure is consulted shown in Fig. 2 and Fig. 3; this overload protection arrangement comprises: fixed part 10, discoid pieces 20, safety switch 30, and safety switch 30 is connected with relay, controls the break-make that whole granulator is powered.
Fixed part 10 is formed at main shaft 1 one end, fixed part 10 edge has the first breach 101, particularly, fixed part 10 has certain thickness, is similar to bulk, its shape can be roughly rounded, also can adopt other shape, such as fan-shaped, rectangle or triangle etc., fixed part 10 and the annexation of main shaft 1 are similar to and are fixedly connected with, by screw fastening or fastening by welding, or directly fixed part 10 and main shaft 1 can be formed an entirety.In front view shown in Fig. 2, main shaft 1 is positioned at the visual field foremost.
Discoid pieces 20 also has certain thickness, discoid pieces 20 offers the holddown groove 201 of shape and fixed part 10 adaptation, holddown groove 201 is provided with the first projection 202 matched with the first breach 101 of fixed part 10, and fixed part 10 is contained in holddown groove 201 and is fixedly installed on main shaft 1 by discoid pieces 20.The setting of the first breach 101 and the first projection 202 is to fixed part 10 and discoid pieces 20 better be fixed.The edge of discoid pieces 20 is formed with a notch part 203.Notch part 203 can be positioned at the optional position at discoid pieces 20 edge, in order to structurally better coordinate with safety switch 30, can be arranged at immediately below discoid pieces 20.
Safety switch 30 is provided with the teat 301 matched with notch part 203, teat 301 is connected to the notch part 203 of discoid pieces 20, when overload situations occurs (overload situations is specifically see the description in background technology), main shaft 1 is by rotor driven rotary, be fixed on fixed part 10 on main shaft 1 along with rotation, the discoid pieces 20 be set on fixed part 10 by holddown groove 201 also can be rotated, cause that notch part 203 is relative with the teat 301 of safety switch 30 to be rotated, originally the two contacting finally can disengage, so, the trigger point that can disconnect as trigger relay is disengaged by the teat of safety switch 30 301 and notch part 203, so safety switch 30 is constructed to the ON/OFF by the contact of teat 301 and notch part 203/disengage control relay.
In some preferred embodiments, the degree of depth of holddown groove 201 is greater than the thickness of fixed part 10, and discoid pieces 20 and fixed part 10 so can be made more firmly to fix.Discoid pieces 20 is in ligulate.
