Abstract
The utility model relates to a material level control device used for a foam pre-expander, and the material level control device is used for detecting and controlling the material level in a barrel of the foam pre-expander. At present, the material level control device used for the foam pre-expander is unreasonable in structural design and unreliable in performance, is often subjected to detection malfunction and has difficulty in accurate and effective material level detection in the barrel of the foam pre-expander. The material level control device provided by the utility model is characterized by comprising a sensor I, a sensor II and a rack body, wherein the sensor I and the sensor II are arranged on the rack body and positioned at the same height. The material level control device provided by the utility model is reasonable in structural design and reliable in performance, and can accurately and effectively detect the material level in the barrel of the foam pre-expander.
Description
Technical field
The utility model relates to a kind of charge level control device, especially relates to a kind of charge level control device that is used for the foam prefoaming machine, belongs to parts in the foam prefoaming machine, is used for detecting and controlling the height of foam prefoaming machine cylindrical shell material level.
Background technology
The structural design of charge level control device that is used for the foam prefoaming machine at present is reasonable inadequately; Performance is reliable inadequately, occurs detecting malfunctioning situation through regular meeting, is difficult to the accurate and effective material level in the foam prefoaming machine cylindrical shell and detects; When adopting existing charge level control device to carry out issuance of materials; The degree of accuracy of issuance of materials is relatively poor, usually between per thousand milligrams of 0.3-0.8 grammes per square metres, thereby influences the quality of froth pulp.As in the process of the level sensor that uses Korea S's import, when the steam composition in the foaming machine is high, will make level sensor be stained with the particulate material of foam, cause faulty sensor; As when using an infrared radiation inductor separately,, will cause the infrared radiation inductor malfunctioning in case top foam beads is thrown height a bit.
The utility model content
The purpose of the utility model is to overcome the above-mentioned deficiency that exists in the prior art; And a kind of reasonable in design is provided; Dependable performance, the charge level control device that is used for the foam prefoaming machine that the material level in the foam prefoaming machine cylindrical shell that can be accurate and effective detects.
The utility model addresses the above problem the technical scheme that is adopted: these characteristics that are used for the charge level control device of foam prefoaming machine are: comprise sensor, No. two sensors and support body; A said sensor and No. two sensors are installed on the support body, and the position at this sensor and No. two sensor places is positioned at sustained height.
The said support body of the utility model is " H " font structure.
Said No. two sensors of the utility model are the infrared radiation inductor.
The utility model compared with prior art has the following advantages and effect: simple in structure, reasonable in design; Scientific arrangement; The material level in the foam prefoaming machine cylindrical shell that can be accurate and effective detects, and makes the degree of accuracy of issuance of materials reduce to the 0.1-0.2 grammes per square metre from per thousand milligrams of original 0.3-0.8 grammes per square metre errors, has improved the degree of accuracy of material grammes per square metre greatly; Effectively guarantee the grammes per square metre uniformity of formed package product and foam board product, improved the quality of product.
The utility model detects the material level in the charging basket through a sensor and No. two sensors jointly, has improved the performance of charge level control device greatly, detects more stable.
Description of drawings
Fig. 1 is the structural representation that is used for the charge level control device of foam prefoaming machine among the utility model embodiment.
Fig. 2 is the structural representation of charge level control device when work that is used for the foam prefoaming machine among the utility model embodiment.
Fig. 3 is that the charge level control device that is used for the foam prefoaming machine among the utility model embodiment is installed in the structural representation on the cylindrical shell.
The specific embodiment
Below in conjunction with accompanying drawing and through embodiment the utility model is done further to specify, following examples are to the explanation of the utility model and the utility model is not limited to following examples.
Embodiment.
Referring to Fig. 1 to Fig. 3, the charge level control device that is used for the foam prefoaming machine in the present embodiment comprises sensor 1, No. two sensors 2 and support bodys 3, and wherein, support body 3 is " H " font structure.
A sensor 1 and No. two sensors 2 in the present embodiment are installed on the support body 3; The position at this sensor 1 and No. two sensor 2 places is positioned at sustained height; Promptly a sensor 1 and No. two sensors 2 and come on the sustained height are used to detect the material level of sustained height.
No. two sensors 2 in the present embodiment are for can adopt the infrared radiation inductor.
Charge level control device in the present embodiment belongs to parts in the foam prefoaming machine; Be used for the material level of the cylindrical shell 4 that is positioned at the foam prefoaming machine is detected and controls, during use, this charge level control device be installed on the cylindrical shell 4; Jointly the detection thing 5 in the cylindrical shell 4 is detected through a sensor 1 and No. two sensors 2; When sensor 1 and No. two sensors 2 detect when detecting thing 5 jointly, explain that the material level in the cylindrical shell 4 has arrived desired value, at this moment; Coherent signal is passed to the control system of foam prefoaming machine, and the foam prefoaming machine is out of service.
In addition, need to prove, the specific embodiment described in this specification, its zero, the shape of parts, institute's title of being named etc. can be different, the above content described in this specification only is to be illustrated what the utility model structure did.Allly conceive the equivalence that described structure, characteristic and principle do according to the utility model patent and change or simple change, include in the protection domain of the utility model patent.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; Only otherwise depart from the structure of the utility model or surmount the defined scope of these claims, all should belong to the protection domain of the utility model.
