Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model use state.
Fig. 2 is the utility model use state enlarged diagram.
Fig. 3 is the enlarged diagram in the portion A in the utility model Fig. 2.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing 1 to Fig. 3.
It is empty, cylinder 1 inside cylinder 1 by Fig. 1 to Fig. 3 it is found that a kind of safety guard of rubber mixing machine, including cylinder 1
Interior sealing sliding is provided with piston 2, the push rod 3 stretched out outside cylinder 1 is fixed on piston 2, cylinder 1 and 3 end of push rod are all provided with
There is pivoted housing 4, two pivoted housings 4 are connect with two rollers 5 of open mill respectively, are fixed on cylinder 1 positioned at 3 side pivoted housing 4 of push rod
External touch switch 6；Piston 2 will be divided into epicoele 7 and cavity of resorption 8 in cylinder 1, be filled with liquid, piston 2 in epicoele 7 and cavity of resorption 8
It is equipped with the first check valve 9 and second one-way valve 10 of connection epicoele 7 and cavity of resorption 8,10 knot of the first check valve 9 and second one-way valve
Structure is identical, contrary, the first spring 11 is equipped in epicoele 7,11 both ends of the first spring are respectively held against piston 2 and main body upper wall.
The main body upper end is equipped with sealing cover 12, and touch switch 6 is through 13 height of fixed link on sealing cover 12.
Sealing ring 14 is equipped between the sealing cover 12 and main body.
First check valve 9 includes being provided with the first slot 15 and the second slot 16 of 2 two sides of piston, the first slot 15 and the
It is equipped with partition 17 between two slots 16, offers the bellmouth of connection the first slot 15 and the second slot 16 on partition 17, in the second slot 16
Plug 18 equipped with taper, plug 18 are caught in being connected to for the first slot 15 of partition and the second slot 16 in bellmouth.
The plug 18 is connect through second spring 19 with 16 side wall of the second slot, and plug 18 is pressed to taper by second spring 19
Hole.
When the utility model is used,
The position of 1 inner piston 2 of cylinder is adjusted according to the distance between roller 5, and selectes the first spring 11 of suitable elastic force,
Liquid is filled in epicoele 7 and cavity of resorption 8, is then sealed cylinder 1 with sealing cover 12, the pivoted housing 4 of the present apparatus is fixed on mill
On 5 axis of roller of machine, pivoted housing 4 and roll shaft are rotatablely connected, and starting open mill starts to produce.
When the load between roller 5 increases, roller 5 pulls pivoted housing 4 to the direction deviated from, lives at this point, push rod 3 pulls
Plug 2 is mobile to 7 direction of epicoele, compresses 7 space of epicoele, and pressure increases in epicoele 7, and liquid is flowed through second one-way valve 10 in epicoele 7
Enter in cavity of resorption 8, and compress the first spring 11,3 end of push rod due to touching touch switch 6 far from cylinder 1, cut by mill electromechanical source
It is disconnected, cleaning and maintenance can be carried out to open mill at this time.
After maintenance, when not overloading between roller 5, the first spring 11 discharges elastic force, pushes piston 2 to cavity of resorption 8
Direction is mobile, and liquid enters in epicoele 7 through the first check valve 9 in cavity of resorption 8 at this time, until the first spring 11 is returned to initial shape
When state, i.e. roller 5 are in normal production status.
When in use, the first spring 11 for selecting suitable elastic force can make the distance between roller 5 stablize, and run suitable
Freely, when generate overload when can impact of the cushion load to roller 5, also can overload eliminate after Rapid reset, it is extra to avoid
Tedious steps.
When overloading generation, pressure increases in epicoele 7, and the liquid in the first slot 15 of second one-way valve 10 pushes plug open
18, liquid enters cavity of resorption 8 through the first slot 15, the second slot 16 out of epicoele 7, balances pressure in epicoele 7 and cavity of resorption 8, when pressure is flat
After weighing apparatus, second spring 19 pushes plug 18 to compress bellmouth, separates the circulation of liquid in epicoele 7 and cavity of resorption 8；Conversely, when overload
After elimination, the elastic force release accumulated on the first spring 11 pushes piston 2 to move down, pressure rise in cavity of resorption 8, the first check valve 9
Liquid in first slot 15 pushes plug 18 open, and liquid enters epicoele 7 through the first slot 15, the second slot 16 out of cavity of resorption 8, balances epicoele
7 and cavity of resorption 8 in pressure, after pressure balance, second spring 19 pushes plug 18 to compress bellmouth, separates in epicoele 7 and cavity of resorption 8
The circulation of liquid.
The utility model compared with prior art, has the advantages that protective device can 1) when overloading generation
Automatic trigger touch switch cuts off open mill power supply, prevents injury of the roller to staff；2) after overloading elimination, protection
Device can automatically reset, and operate without staff, highly-safe using simplicity.
