A kind of wide cross section atmosphere protection roller kilns of band contact product space detection device
Technical field
The present invention relates to roller kilns equipment technical field, refer more particularly to a kind of band contact product space detection device
Wide cross section atmosphere protection roller kilns.
Background technology
Displacement chamber component in atmosphere protection roller kilns, is to utilize certain gas indoor air to be displaced and makes to have leisure
Gas can not enter in atmosphere protection roller kilns.Due to displacement its bad environments indoor, such as factors such as temperature are high, smog is big, and add
Upper photoelectricity, the restriction of laser sensor technology, i.e. sensor light are difficult to through smog, and then are difficult to accurately detection displacement indoor
The position of product, it is impossible to accurately the signal of the position at product place is fed back to corresponding actuator so that it is according to accordingly
The predetermined action such as program completes to open the door accordingly, closes the door, product stopping, transmission, and then can cause that product is destroyed, mechanism is broken
Bad or that product quality is impaired accident so that produce and cannot run the most continuously.
The roller rod span of existing wide roller kiln is long, if do not supported between roller rod, roller rod will be made to have
One amount of deflection the biggest, affects the conveying operation of product.The detection of existing product space is the one end by being arranged on roller rod, and
And its structure is complicated, its in the course of the work its detected signal weak and extremely unstable, it is impossible to the most precisely and reliable
The correct signal of product space is fed back to corresponding actuator, thus it is difficult to ensure that normal production operation process.Have
In consideration of it, for how searching out a kind of simple in construction, stable and reliable in work and just detect the device of product space detection accurately
It is particularly important.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, stable and reliable in work and inspection
Survey the wide cross section atmosphere protection roller kilns of the device of band contact product space detection accurately.
For achieving the above object, technical scheme provided by the present invention is: a kind of band contact product space detection device
Wide cross section atmosphere protection roller kilns, described atmosphere protection roller kilns include roller kilns frame, displacement room, many for conveying products
Group roller rod and the multiple rollers being arranged on each described roller rod and actuator, it is characterised in that: described atmosphere protection roller
It is interior for detecting the position detecting device of described product space that road kiln also includes being arranged on described roller kilns frame, and described position is detected
Device includes being arranged at least one position detecting mechanism that described roller rod two ends are fixed between the strong point, and each described position is examined
Survey mechanism and include the roller rod strong point for contacting with described roller rod bottom, for installing the support of the described roller rod strong point
Seat, LOAD CELLS, for install described LOAD CELLS LOAD CELLS mounting seat and be arranged on described roller rod support
Pressure transmission assembly between point and LOAD CELLS, the product pressure that the wherein said roller rod strong point is born is by described pressure
Force transfer unit is transferred on described LOAD CELLS.
Further, described LOAD CELLS is arranged on outside bottom, described displacement room by described LOAD CELLS mounting seat
Portion.
Preferably, described pressure transmission assembly includes being fixedly connected between the described roller rod strong point and LOAD CELLS
The axis of guide, the fairlead that the wherein said axis of guide is provided by constitutes being slidably connected of vertical direction with described bearing.
Further, the described roller rod roller diameter thereon of described position detecting mechanism is installed more than its roller rod adjacent
On roller diameter.
Compared with prior art, this programme is examined by the structure using LOAD CELLS combined with frame for movement
Survey product space in expanded letter atmosphere protection roller kilns, owing to this position detecting device is contact, therefore in product work process
In, no matter which product its through roller rod, the most reliable near load cell signal sensitive and reactive and the transmission of product, and
And the mechanical wounding to product will not be produced because of this kind of version.

Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described:
Seeing shown in accompanying drawing 1 to 2, the wide cross section atmosphere of a kind of band contact product space detection device described in the present embodiment is protected
Protect roller kilns, these atmosphere protection roller kilns include roller kilns frame 1, displacement room 6, for conveying products 4 many groups roller rod 2 and install
Multiple rollers 3 on each roller rod 2 and actuator 5.These atmosphere protection roller kilns also include being arranged in roller kilns frame 1
For detecting the position detecting device of product 4 position, this concrete position detecting device includes being arranged on fixing of roller rod 2 two ends
At least one position detecting mechanism 7 between support point, each position testing agency 7 includes for contacting with roller rod 2 bottoms
The roller rod strong point 71, support seat 72, LOAD CELLS 74 for the mounted roller rod strong point 71, it is used for LOAD CELLS 74 is installed
LOAD CELLS mounting seat 73 and be arranged on the pressure transmission assembly between the roller rod strong point 71 and LOAD CELLS 74, its
Product 4 pressure that the central roll rod strong point 71 is born is by pressure transmission component passes to LOAD CELLS 74.
See shown in accompanying drawing 3, it is contemplated that in displacement room 6, environment is relatively more severe, the above-mentioned LOAD CELLS peace in this programme
Dress seat 73 is arranged on outside displacement bottom, room 6, i.e. LOAD CELLS 74 is arranged on displacement room 6 by LOAD CELLS mounting seat 73
Outside, it is to avoid LOAD CELLS 74 contacts with the gas in displacement room 6.
Concrete, the above-mentioned pressure transmission assembly in this programme includes being fixedly connected on the roller rod strong point 71 and weighing and sensing
The axis of guide 75 between device 74, the fairlead 76 that wherein axis of guide 75 is provided by and bearing constitute the slip of vertical direction even
Connect.
It addition, so that above-mentioned position detecting device possesses more preferable sensitivity, i.e. product 4 through position detection dress
Have a stronger signal can to during putting LOAD CELLS 74, this programme is provided with the roller rod 2 of position detecting mechanism 7
Roller 3 diameter thereon is more than roller 3 diameter on its roller rod 2 adjacent, to ensure when product 4 is through being provided with the inspection of above-mentioned position
During surveying the roller rod 2 of device, it is possible to make this roller rod 2 can be made the title near product 4 position by additional product 4 pressure
Weight sensor 74 produces a higher signal, and then makes this signal feed back to corresponding actuator 5, it is ensured that hold accordingly
Relevant action accurately and timely does in row mechanism 5.
The examples of implementation of the above are only the preferred embodiments of the invention, not limit the enforcement model of the present invention with this
Enclose, therefore the change that all shapes according to the present invention, principle are made, all should contain within the scope of the present invention.
