[0028] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0029] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude other embodiments.

[0030] Embodiment 1

[0031] Referring to Figure 1 , this embodiment provides a composite machine induction shutdown protection device, including a composite machine body. The composite machine body includes a frame 1 and a plurality of axles 2 arranged on the frame 1; an induction mechanism is arranged at the axle 2;

[0032] The induction mechanism includes a power switch 3 arranged on the frame 1 through a disassembly and assembly mechanism. Through the set disassembly and assembly structure, the power switch 3 can be quickly installed or detached from the frame 1 for the purpose of quick replacement. The power switch 3 is provided with a sensor 4 through an amplitude adjustment mechanism 18. The amplitude adjustment mechanism 18 is a flexible tube, the sensor 4 is an infrared sensor, and an amplitude adjustment knob is arranged on the infrared sensor. The induction range of the infrared sensor is 1 - 2 cm. When the infrared sensor does not sense the product flow within the range of 1 - 2 cm, it automatically controls the composite machine body to stop running, saving power consumption and prolonging the service life of the equipment motor. At the same time, through the set flexible tube, the position of the sensor 4 can be adjusted to adapt to the position of the axle 2.

[0033] Embodiment 2:

[0034] Referring to Figures 2 - 6, in this embodiment, a disassembly and assembly mechanism is provided for quickly installing and removing the power switch 3 to achieve the purpose of quick replacement;

[0035] The disassembly and assembly mechanism includes a mounting block 5 provided on the frame 1 and an insertion block 6 provided on the top of the power switch 3. A groove for the insertion block 6 to slide and insert is formed on the bottom surface of the mounting block 5, and the top end of the insertion block 6 is chamfered;

[0036] Through holes 7 communicating with the groove are formed on both sides of the mounting block 5. A sliding block 8 is elastically slidably connected in the through hole 7, and the sliding block 8 is slidably connected with the inner wall of the through hole 7. More specifically, a baffle 11 is fixed at the through hole 7. One end of a fixing rod 12 is fixed to the sliding block 8, and the other end of the fixing rod 12 passes through the baffle 11; a return spring 13 is sleeved on the fixing rod 12, and both ends of the return spring 13 are in contact with the baffle 11 and the sliding block 8 respectively. Positioning grooves 9 are formed on both sides of the power switch 3. When the power switch 3 is fixed on the mounting block 5, one end of the insertion block 6 is inserted into the positioning groove 9 under the elastic force of the return spring 13;

[0037] The disassembly and assembly mechanism further includes a driving part for driving the sliding block 8 to move. By the driving part, the movement of the sliding block 8 can be controlled, and it is more convenient to move the two sliding blocks 8 simultaneously

[0038] One side of the sliding block 8 facing the middle of the mounting block 5 has an arc surface 10 and a flat surface. When the power switch 3 is fixed on the mounting block 5, under the elastic force of the return spring 13, the flat surface is in contact with the inner wall of the positioning groove 9, and both ends of the arc surface 10 are respectively inside the positioning groove 9 and the through hole 7;

[0039] A limiting plate 14 is fixed to the fixing rod 12. When the power switch 3 is fixed on the mounting block 5, under the elastic force of the return spring 13, the limiting plate 14 is in contact with the baffle 11;

[0040] In this embodiment, when in use, as Figure 6As shown in the figure, when the power switch 3 is fixed on the mounting block 5, under the elastic force of the return spring 13, the limiting plate 14 contacts the baffle 11, the plane contacts the inner wall of the positioning groove 9, and both ends of the arc surface 10 are respectively inside the positioning groove 9 and the through hole 7. At this time, both the power switch 3 and the insertion block 6 tend to descend. At this time, the top wall of the inner top of the positioning groove 9 contacts the top wall of the sliding block 8, and the sliding block 8 holds the insertion block 6, playing a fixing role; when it is necessary to remove the power switch 3, operate the driving part to make both sliding blocks 8 move away from the insertion block 6. After the sliding block 8 disengages from the positioning groove 9 of the insertion block 6, the power switch 3 can be pulled out; when installing the power switch 3, insert the insertion block 6 into the groove. Due to the elastic force of the return spring 13, both ends of the arc surface 10 are respectively inside the positioning groove 9 and the through hole 7, so the chamfer of the insertion block 6 can exert extrusion on the arc surface 10, making the sliding block 8 move away from the insertion block 6. When the top of the insertion block 6 contacts the inner top wall of the groove, under the elastic force of the return spring 13, the plane contacts the inner wall of the positioning groove 9, and both ends of the arc surface 10 are respectively inside the positioning groove 9 and the through hole 7, fixing the position of the insertion block 6 and the mounting block 5. The function of setting the plane is to reduce the wear of the sliding block 8.

[0041] Embodiment 3:

[0042] Refer to Figure 3 and Figure 5 In this embodiment, a driving part for the disassembly and assembly mechanism in Embodiment 2 is provided. The driving part includes a connecting belt 15 and one end of a support ring 16 fixed on both sides of the mounting block 5. The connecting belt 15 can be deformed and is not affected by the sliding of the sliding block 8 when the power switch 3 is installed. The end of the connecting belt 15 passes through the other end of the support ring 16 and then is connected to the other end of the fixed rod 12. When the power switch 3 is fixed on the mounting block 5, the other end of the fixed rod 12 is between the other end of the support ring 16 and the side surface of the mounting block 5; the driving part further includes a soft sleeve 17 provided on the connecting belt 15;

[0043] In this embodiment, as Figure 5 shown in the figure, when it is necessary to remove the power switch 3, hold the soft sleeve 17 and pull the connecting belt 15 to make the connecting belt 15 move away from the mounting block 5. Since the other end of the fixed rod 12 is between the other end of the support ring 16 and the side surface of the mounting block 5 when the power switch 3 is fixed on the mounting block 5, the moving connecting belt 15 can drive the sliding block 8 to move away from the insertion block 6. After releasing the connecting belt 15, due to the elastic force received by the sliding block 8, each component returns to its initial position.

[0044] It should be understood that, in the development of any actual implementation, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, without undue experimentation, such development efforts will be routine work of design, manufacturing, and production.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
