Description
Technical field
The utility model relates to a kind of router, particularly relates to a kind of air valve structure of improvement.
Background technology
Air valve is responsible for suction and the discharge of gas, is widely used in all kinds of package packing machine, as medicament packing machine.When the transmission shaft of air valve reaches extreme higher position, the air flue of air valve is connected, and start air-breathing, when the transmission shaft of air valve reaches extreme lower position, the air flue of air valve is blocked, and stops suction.But only the line of centers of guaranteed transmission shaft overlaps completely with the line of centers of air flue, just can reach maximum air-breathing degree, which increase setting accuracy requirement, make installation inconvenient, air valve not easily arrives maximum inhale degree, under the effect of the cam of air valve, the transmission shaft up-and-down movement of air valve, simultaneous rotates, and makes between the transmission shaft of air valve and other contact components easy to wear, and easily there is small slip, make the work efficiency drop of air valve.
Utility model content
The purpose of this utility model is just the air valve structure providing a kind of improvement in order to solve the problem.
In order to achieve the above object, the utility model have employed following technical scheme:
A kind of air valve structure of improvement, comprise air flue, motor, transmission shaft, cam and casing, the air valve structure of described a kind of improvement also comprises the first anchor shaft, second anchor shaft, pilot bar and hollow cylinder, described cam is connected with the rotating shaft of described motor, described hollow cylinder is arranged at the top of described transmission shaft, described cam contacts with described hollow cylinder, the top of described casing is provided with through hole, described transmission shaft is through described through hole, described air flue is arranged in described casing, described air flue is connected with described transmission shaft, described first anchor shaft is arranged on described air flue, described first anchor shaft is provided with through hole, described transmission shaft is through the through hole on described first anchor shaft, described second anchor shaft is arranged at described casing top, described second anchor shaft is provided with two through holes, described transmission shaft is through a through hole on described second anchor shaft, described pilot bar is arranged on described first anchor shaft, described pilot bar is through another through hole of described second anchor shaft.
In said structure, the first anchor shaft, the second anchor shaft and pilot bar, when can make transmission shaft up-and-down movement, can not rotate, and avoids the wearing and tearing between transmission shaft and other contact components and small slip, and the situation of the air valve work efficiency drop caused.
Particularly, the diameter of described hollow cylinder is greater than the diameter of described transmission shaft; The contact surface of described hollow cylinder and described cam scribbles wear-resistant protection material; The contact surface of described first anchor shaft and described transmission shaft and the contact surface of described second anchor shaft and described transmission shaft all scribble wear-resistant protection material; Described wear-resistant protection material is graphite powder; Hollow cylinder ensure that the line of centers of transmission shaft overlaps completely with the line of centers of air flue, does not need high-precision installation, and air valve just can be made to reach maximum inhale degree, solves the installation inconvenience of original air valve, not easily reaches the problem of maximum inhale degree.
The beneficial effects of the utility model are:
Diameter in the utility model is greater than the hollow cylinder of transmission shaft diameter, ensure that the line of centers of transmission shaft overlaps completely with the line of centers of air flue, do not need high-precision installation, air valve just can be made to reach maximum inhale degree, solve the installation inconvenience of original air valve, not easily reach the problem of maximum inhale degree, when cam driven transmission shaft up-and-down movement, first anchor shaft of transmission shaft in the utility model, under the effect of the second anchor shaft and pilot bar, when making transmission shaft up-and-down movement, can not rotate, avoid the wearing and tearing between transmission shaft and other contact components and small slip, and the situation of the air valve work efficiency drop caused.
Accompanying drawing explanation
Fig. 1 is the structural representation of the air valve structure of a kind of improvement of the utility model.
In figure: 1-pilot bar, 2-second anchor shaft, 3-air flue, the rotating shaft of 4-motor, 5-cam, 6-hollow cylinder, 7-transmission shaft, 8-casing, 9-first anchor shaft.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the air valve structure of a kind of improvement of the utility model, comprise air flue 3, motor, transmission shaft 7, cam 5 and casing 8, a kind of air valve structure of improvement also comprises the first anchor shaft 9, second anchor shaft 2, pilot bar 1 and hollow cylinder 6, cam 5 is connected with the rotating shaft 4 of motor, hollow cylinder 6 is arranged at the top of transmission shaft 7, cam 5 contacts with hollow cylinder 6, the top of casing 8 is provided with through hole, transmission shaft 7 is through through hole, air flue 3 is arranged in casing 8, air flue 3 is connected with transmission shaft 7, first anchor shaft 9 is arranged on air flue 3, first anchor shaft 9 is provided with through hole, transmission shaft 7 is through the through hole on the first anchor shaft 9, second anchor shaft 2 is arranged at casing 8 top, second anchor shaft 2 is provided with two through holes, transmission shaft 7 is through a through hole on the second anchor shaft 2, pilot bar 1 is arranged on the first anchor shaft 9, pilot bar 1 is through another through hole of the second anchor shaft 2, the diameter of hollow cylinder 6 is greater than the diameter of transmission shaft, hollow cylinder 6 and the contact surface of cam scribble wear-resistant protection material, first anchor shaft 9 all scribbles wear-resistant protection material with the contact surface of transmission shaft 7 and the contact surface of the second anchor shaft 2 and transmission shaft 7, wear-resistant protection material is graphite powder.
