The structure of the exhaust pipe 101 is described so as to facilitate the description and understanding of the exhaust pipe screening device 91 later. The exhaust pipe 101 includes a first pipe section 1011 and a second pipe section 1013 connected in sequence, the first pipe section 1011 and the second pipe section 1013 are preferably concentrically arranged, the outer diameter of the second pipe section 1013 is larger than the outer diameter of the first pipe section 1011, and an end surface of the second pipe section 1013 near the first pipe section 1011 is referred to as a first end surface 1012, or, in other words, the second pipe section 1013 is connected to the first pipe section 1011 through the first end surface 1012; the second tube section 1013 has an enlarged end configuration throughout the exhaust pipe 101; the end of the first pipe section 1011 acts as a microwave emitting end in a direction away from the second pipe section 1013. Meanwhile, the exhaust pipe 101 is assembled and connected with other parts of the magnetron through the first pipe section 1011. In view of the fact that the exhaust pipe 101 referred to in the present application is identical to the exhaust pipe of the magnetron in the related art, further description is not given.

Meanwhile, for ease of understanding, considering that the exhaust pipe 101 is in an elongated circular pipe shape as a whole, in this application, the length direction of the exhaust pipe 101 is collinear with a straight line where the axes of the circular pipes of the first pipe section 1011 and the second pipe section 1013 are located, and correspondingly, the length direction is bidirectional, including a direction from the first pipe section 1011 to the second pipe section 1013 and also including a direction from the second pipe section 1013 to the first pipe section 1011, which is the same as conventional knowledge of the length direction of the elongated circular pipe by people.

As shown in fig. 23 to 30, the exhaust pipe screening device 91 includes a vibration plate 912, the vibration plate 912 is provided with an exhaust pipe hopper 913, a spiral conveying rail 914 is provided on the outer side of the circumference of the exhaust pipe hopper 913, the exhaust pipe 101 can move along the spiral conveying rail 914, a circumferential screening portion 915 and an angle adjusting section 916 are provided in this order along the moving direction of the exhaust pipe 101, the circumferential screening portion 915 enables the exhaust pipe 101 to be conveyed in a vertically advanced state, and the angle adjusting section 916 enables the exhaust pipe 101 to be conveyed in a horizontally advanced state after being adjusted from the vertically advanced state. As shown in fig. 8, the vertically advanced state is that the length direction of the exhaust pipe 101 is the same as the moving direction of the exhaust pipe 101, and the horizontally advanced state is that the length direction of the exhaust pipe 101 is perpendicular to the moving direction of the exhaust pipe 101.

It should be noted that, although the spiral transportation rail 914 is in the form of a spiral line, the entire moving track of the exhaust pipe 101 is similar to the spiral line; however, in view of the calculus, the movement direction of the exhaust pipe 101 may be divided into a plurality of straight movement tracks, and in order to avoid understanding deviation, in this application, the movement direction of the exhaust pipe 101 is a movement track direction at a certain moment (or within a very short period of time), and this movement direction may be regarded as a straight movement track direction in the calculus field.

In vibration dish 912, a large amount of blast pipes 101 are randomly stacked, crisscross, this application sets gradually circumference screening portion 915, angle adjustment section 916 through at spiral transportation track 914, be in the blast pipe 101 of various position forms in vibration dish 912, at first utilize circumference screening portion 915 to carry out the screening to the blast pipe 101 that is in vertical advance state, make through circumference screening portion 915's blast pipe 101, its length direction is the same with its direction of movement, keep vertical advance's mode to carry, then utilize angle adjustment section 916, adjust the blast pipe 101 of vertical advance state to the state of transversely advancing, make blast pipe 101 can remove with this kind of specific position state of transversely advancing, make screening device can realize the directional screening to blast pipe 101, on the one hand, the directional equipment of follow-up magnetron of being convenient for, on the other hand can effectively improve the production efficiency of every blast pipe 101 orientation process, degree of automation, the manual work of having removed the pendulum or orientation to blast pipe 101.

The spiral conveying rail 914 is set to a spiral ascending state, preferably a gradually expanding spiral ascending state, so that after the exhaust pipe 101 which does not conform to the vertical advancing state is screened out by the circumferential screening portion 915, the corresponding exhaust pipe 101 automatically falls into other positions in the vibration plate 912, and does not fall outside the vibration plate 912.

The circumferential screening portion 915 includes a circumferential screening groove 9151, the circumferential screening groove 9151 is disposed on a track surface 9141 of the spiral conveying track 914, such that the track surface 9141 at the circumferential screening portion 915 forms a circumferential screening passage 9152, and a radial length dimension of the circumferential screening passage 9152 is smaller than a length of the exhaust pipe 101, slightly larger than a maximum diameter of the exhaust pipe 101, or equal to the maximum diameter of the exhaust pipe 101, so that the exhaust pipe 101 having a length direction of the exhaust pipe 101 inconsistent with a moving direction of the exhaust pipe 101 cannot pass through the circumferential screening passage 9152 and falls into the circumferential screening groove 9151 under the action of self gravity. The exhaust pipe 101 passing through the circumferential screening channel 9152 is illustrated in a vertically advanced state and then fed to the angle adjustment section 916 for adjustment of a specific state.

Preferably, the circumferential screening groove 9151 is disposed on a side of the raceway surface 9141 adjacent to the exhaust pipe hopper 913, such that the exhaust pipe 101 cannot pass through the circumferential screening channel 9152, and can slide directly from the circumferential screening groove 9151 onto the upstream spiral conveyor track 914 or into the exhaust pipe hopper 913 with its own weight.

The upper surface of the spiral transportation rail 914 carrying the exhaust pipe 101 is denoted as a rail surface 9141, and the spiral transportation rail 914 further includes an outer peripheral plate 9142, wherein the outer peripheral plate 9142 is connected to the outer edge of the rail surface 9141, and encloses the movement of the exhaust pipe 101, so that the exhaust pipe 101 moves inside the vibration plate 912, and the exhaust pipe 101 is prevented from moving outside the vibration plate 912.

Accordingly, since the circumferential screening groove 9151 is disposed on the side of the track surface 9141 close to the exhaust pipe hopper 913, the track surface 9141 located between the circumferential screening groove 9151 and the outer peripheral plate 9142 can be regarded as the circumferential screening channel 9152.

For the angle adjustment section 916, the track surface 9141 is inclined downward at least at the angle adjustment section 916, i.e., at least the angle B between the track surface 9141 at the angle adjustment section 916 and the vertically upward direction is obtuse, preferably 93 ° -110 °. If the extending direction of the outer peripheral plate 9142 is vertical, the angle B may be regarded as the angle between the track surface 9141 at the angle adjustment section 916 and the outer peripheral plate 9142.

The angle adjusting section 916 is provided with a transition arm 9161, one end of the transition arm 9161 is connected to the track surface 9141, the other end extends obliquely upward along the movement direction of the exhaust pipe 101, a transition cavity 9162 is formed between the transition arm 9161 and the track surface 9141, and the opening height of the transition cavity 9162 gradually increases along the movement direction of the exhaust pipe 101. Thus, after the exhaust pipe 101 passes through the circumferential screening channel 9152 in the vertically advanced state, the exhaust pipe 101 moves between the transition arm 9161 and the outer peripheral plate 9142, and as the track surface 9141 at the angle adjustment section 916 is inclined downward, the exhaust pipe 101 will have a sliding trend, and the first pipe section 1011 will slide into the transition cavity 9162 under its own weight as the opening height of the transition cavity 9162 increases gradually until it is larger than the outer diameter of the first pipe section 1011, at this time, the first end surface 1012 of the second pipe section 1013 abuts against the transition arm 9161 to prevent the exhaust pipe 101 from sliding further, and accordingly, the exhaust pipe 101 automatically changes from the vertically advanced state to the horizontally advanced state at this time, so as to implement the directional screening process for the exhaust pipe 101.

In consideration of the lateral advancing state, the length direction of the exhaust pipe 101 is perpendicular to the moving direction of the exhaust pipe 101, and in order to ensure that the exhaust pipe 101 can be kept in the lateral advancing state relatively stably, the occurrence of rattling or hunting is avoided. The track surface 9141 between the transition arm 9161 and the outer peripheral plate 9142 is provided with a directional clamping groove 917, a first side wall 9171 of the directional clamping groove 917 can be abutted against a first end surface 1012 of the exhaust pipe 101, and the radial length dimension of the directional clamping groove 917 is greater than or equal to the length of the second pipe section 1013, so that after the exhaust pipe 101 automatically changes from a vertical advancing state to a horizontal advancing state, one side (upper side) of the second pipe section 1013 can be abutted against the transition arm 9161 through the first end surface 1012, and meanwhile, the other side (lower side) of the second pipe section 1013 can also enter the directional clamping groove 917, and a certain abutting limiting relationship exists between two sides of the exhaust pipe 101 through the first end surface 1012 and the directional clamping groove 917, and the exhaust pipe 101 can be ensured to relatively stably keep the horizontal advancing state to move.

Then, after the directional clamping groove 917 can perform relatively stable bearing clamping on the exhaust pipe 101, the transition arm 9161 can be not extended any more, the transverse advancing state of the exhaust pipe 101 can be kept only through the directional clamping groove 917, then the corresponding structures at the position of the proper extending angle adjusting section 916, specifically, the extending spiral conveying track 914 and the directional clamping groove 917, the transition arm 9161 is not required to be prolonged, after the upper side of the exhaust pipe 101 is ensured to have no space obstruction of the transition arm 9161 and other parts, the upper side of the exhaust pipe 101 can be grabbed one by using a manual or mechanical arm, and subsequent magnetron assembly is performed. Therefore, the method can realize the purpose of directional screening of the exhaust pipes 101 and even subsequent material taking one by one, and greatly improves the production efficiency and the automation degree of the directional process of each exhaust pipe 101.

In the implementation process, after the directional screening process of the circumferential screening portion 915 and the angle adjusting section 916, the exhaust pipe 101 is still approximately horizontally placed on the spiral conveying track 914 due to the horizontally advancing state of the exhaust pipe 101, and when the material is taken, only the arc outer wall with a small arc length of the outer side of the exhaust pipe 101 can be grabbed, so that the exhaust pipe 101 is difficult to be grabbed more firmly, and the situation of blanking after grabbing is very easy to occur.

For this reason, as shown in fig. 2 to 5, the present embodiment improves the discharging-related structure of the screening device on the basis of embodiment 1. The screening device comprises a discharging reversing section 918, wherein a feeding end of the discharging reversing section 918 is connected with a discharging end of an angle adjusting section 916, and the screening device is used for adjusting the exhaust pipe 101 from a transverse advancing mode to a transverse advancing mode and conveying the exhaust pipe 101 in a mode that the direction from a first pipe section 1011 of the exhaust pipe 101 to a second pipe section 1013 of the exhaust pipe 101 is vertical upwards. Therefore, when the exhaust pipe is kept in a transversely forward state, the exhaust pipe which is approximately horizontally arranged is vertically arranged, and the second pipe section 1013 with the relatively large outer diameter faces upwards, so that a manual or mechanical arm is arranged above the exhaust pipe 101, the whole outer circumference of the second pipe section 1013 can be directly forced, the firmness in grabbing can be effectively improved, and the condition of blanking after grabbing is prevented.

Specifically, along the moving direction of the exhaust pipe 101, the discharging reversing section 918 includes a connecting section 9181 and a torsion section 9182 that are sequentially connected, and the torsion section 9182 is connected with the discharging end of the angle adjusting section 916 through the connecting section 9181. For ease of understanding, the connection section 9181 and the torsion section 9182 can be regarded as the extending structure of the angle adjusting section 916 in embodiment 1, and the main structures of the connection section 9181 and the torsion section 9182 are consistent with the spiral conveying track 914, and the track surface 9141 and the outer peripheral plate 9142 are both provided with extending orientation slots 917 for maintaining the orientation state of the exhaust pipe 101 and enabling the exhaust pipe 101 to move along the extending direction of the orientation slots 917, and considering that the structures are substantially consistent, details will not be repeated.

Accordingly, for the connection section 9181 and the torsion section 9182, the first end surface 1012 of the exhaust pipe 101 can also be kept in contact with the first side wall 9171 of the orientation groove 917 during the movement of the connection section 9181 or the torsion section 9182.

The discharging reversing section 918 comprises a protecting plate 9184, the protecting plate 9184 is connected with an outer peripheral plate 9142 of the connecting section 9181 and an outer peripheral plate 9142 of the torsion section 9182, one side of the protecting plate 9184, which is close to the outer peripheral plate 9142, is marked as a second side wall 91841, when the exhaust pipe 101 moves to the connecting section 9181 or the torsion section 9182, the first end surface 1012 of the exhaust pipe 101 can be simultaneously abutted with the first side wall 9171 and the second side wall 91841. Because the discharging reversing section 918 is used for reversing the exhaust pipe 101, the protecting plate 9184 is additionally arranged, so that a structure similar to a track can be formed on two sides of the exhaust pipe 101 by the protecting plate 9184 and the directional clamping grooves 917, two sides of the exhaust pipe 101 can be limited in a butt joint manner, the exhaust pipe 101 can move and be reversed along the protecting plate 9184 and the directional clamping grooves 917, and meanwhile, the situation that the exhaust pipe 101 is free from shaking, falling and the like in the reversing process is ensured.
