Abstract
The invention discloses a sticking protection device for an upper punch and aims to solve the problem that stoppage for checking suspended punching is often needed during tabletting of medium- and low-speed table presses. The sticking protection device for the upper punch is characterized by comprising an upper punch descent rail, an upper punch descent pressing plate, a pin, a spring, an adjusting screw, a holder, a screw, an arc washer, a flat washer, a nut and a proximity switch. The adjusting screw is connected with the upper punch descent pressing plate. The spring and the arc washer are sleeved on the adjusting screw before the adjusting screw is disposed into an inner hole of the holder. The holder is fixedly connected with upper punch descent rail through the screw. The upper punch descent rail is connected with the upper punch descent pressing plate through the pin. The flat washer and the nut are disposed on the adjusting screw at the upper end of the holder. The proximity switch is fixed on the upper punch descent rail. The sticking protection device for the upper punch is widely applied to medium- and low-speed table presses, has the functions of automatic detection and stoppage and automatic alarming and is low in manufacturing cost and high in production efficiency.
Description
Technical field
The present invention relates to a kind of protective device, particularly relate to the upper punch sticking protection device on tablet press machine in a kind of pharmaceutical machine.
Background technology
In the industries such as medicine, chemical industry, food, usually the pressed powder or granular material with certain effect are pressed into tablet form and form tablet or health products, the machinery being pressed into tablet form is called tablet press machine by people usually, mould compressing for material is called punch die by tablet press machine, and punch die is made up of upper punch, middle mould, lower punch.In tableting processes, due to the difference of the factor such as mobility, viscosity, temperature of material, often can occur to produce to hang because material is bonded at upper punch surface to rush phenomenon, time serious, upper punch clashes into the descending rail of upper punch because sticking does not freely fall, and damages parts.Without upper punch sticking protection device on current middle low speed tablet press machine; process is hung and rushed the conventional method of phenomenon is exactly cycle at set intervals; after stopping compressing tablet shutdown; punch whether flexibly movement in upper punching is checked on each one by one by manual type; pinpointing the problems, it is clean to pull down in time; to take a lot of work effort; reduce production efficiency; and on high speed tablet press, have a kind of upper punch sticking detection device; as long as anti-the jump onto the tracks generation slight impact of upper punch on upper punch descending rail porch and checkout gear; by conputer controlled as formulated as sticking, hard stop.This device sensitivity is high; too high to the characteristic requirements of factory supplies, control very tight, device fabrication cost is high in addition; low speed tablet press machine cannot be applied in common, then research and design must go out a kind of upper punch sticking protection device that can be applicable to that middle low speed tablet press machine uses.
Summary of the invention
The object of the invention is to provide a kind of novel upper punch sticking protection device, hang with low speed tablet press machine frequent shutdown inspection in tableting processes in solving and rush phenomenon problem.
A kind of upper punch sticking protection device of the present invention can adopt following technical scheme to implement: it comprises the descending rail of upper punch, the descending pressing plate of upper punch, bearing pin, spring, adjusting screw(rod), holder, screw, circular arc packing ring, plain washer, nut and proximity switch, wherein adjusting screw(rod) is connected with the descending pressing plate of upper punch, spring and circular arc gasket sleeve being contained in after on adjusting screw(rod) loads adjusting screw(rod) in the endoporus of holder, with screw, holder and the descending rail of upper punch are fastenedly connected, the descending rail of upper punch and the descending pressing plate of upper punch pass through pinned connection, plain washer, nut is contained in the upper end of adjusting screw(rod), proximity switch is fixed on the descending rail of upper punch.All the other parts are same as the prior art or similar.
Compared with prior art, its main feature is a kind of upper punch sticking protection device designed and produced according to technique scheme:
1 produces to hang rush phenomenon once generation sticking, and the descending pressing plate of upper punch rotates up around bearing pin, and during close to " proximity switch ", tablet press machine autostop, need not artificial real-time inspection, avoids the meaningless shutdown inspection time, improves production efficiency;
2, upper punch sticking protection device structure is simple, low cost of manufacture;
3, upper punch sticking protection device sensitivity is relatively low, less demanding to downtrodden material characteristic, strong adaptability;
4, the blank of unprotect device on middle low speed tablet press machine has been filled up in the invention of upper punch sticking protection device, avoids and rushes phenomenon and the parts that cause damage because hanging, extend the service life of machine, reduce production cost.
Accompanying drawing explanation
Fig. 1, a kind of upper punch sticking protection device structural representation;
The A-A sectional view of Fig. 2, Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
As Fig. 1, shown in Fig. 2, a kind of upper punch sticking protection device of the present invention comprises the descending rail 1 of upper punch, the descending pressing plate 2 of upper punch, bearing pin 3, spring 4, adjusting screw(rod) 5, holder 6, screw 7, circular arc packing ring 8, plain washer 9, nut 10 and proximity switch 11, wherein adjusting screw(rod) 5 is connected with the descending pressing plate 2 of upper punch, by spring 4, circular arc packing ring 8 is sleeved on after on adjusting screw(rod) 5 and adjusting screw(rod) 5 is loaded in the endoporus of holder 6, with screw 7, holder 6 and the descending rail 1 of upper punch are fastenedly connected, the descending rail of upper punch 1 and the descending pressing plate 2 of upper punch are connected by bearing pin 3, plain washer 9, nut 10 is contained on the adjusting screw(rod) 5 of holder 6 upper end, proximity switch 11 is fixed on the descending rail 1 of upper punch.
During a kind of upper punch sticking protection device work be made into according to said structure form; when upper punch to hang because of sticking rush phenomenon time; the descending pressing plate 2 of upper punch is encountered in the upper end of upper punch; the descending pressing plate of upper punch rotates up around bearing pin 3; the descending pressing plate of upper punch sends stopping signal and stopping alarm when proximity switch 11, makes operating personnel process in time and to fix a breakdown.
