[0002] In the sorting stage of tobacco logistics and distribution, a large number of sorting devices operate continuously to ensure the accurate and efficient classification and distribution of cigarettes. However, during long-term operation, the mechanical parts of the equipment wear out and age, which can easily lead to abnormal vibrations. For example, loose drive belts and changes in gear meshing clearances in sorting machines can cause increased equipment vibration, affecting sorting accuracy and efficiency. Moreover, an unstable installation foundation and unstable temperature and humidity in the operating environment can further complicate the vibration problem.

[0027] Example 1:

[0028] like Figure 1 As shown, the support rod 104 provides direct or indirect support to various functional components. During use, the operator can hold the end of the support rod 104 and insert the mounting base 106 into the mechanical equipment to be tested, preventing close contact with the equipment and thus mitigating the risk of injury. To ensure the strength of the support rod 104 and to allow for shape adjustment based on the site conditions, the support rod 104 can be made of a bendable solid iron rod or a bamboo-joint tube. A handle 105 can be provided at the gripping end of the support rod 104 for easy handling.

[0029] like Figure 1As shown, the mounting base 106 and the fixing base 101 cooperate to support the vibration sensor 103. Specifically, to facilitate observation of the engagement point between the vibration sensor 103 and the mechanical device under test during use, the mounting base 106 is provided with claw-shaped structures 102 evenly distributed circumferentially and protruding to one end. The fixing base 101 is connected to each claw of the claw-shaped structure 102 via an elastic connector 107, so that the fixing base 101 is suspended in the space formed by the claw-shaped structure 102, thereby providing a certain stroke for the fixing base 101. The elastic connector 107 can be in the form of a spring or an elastic band. The end of the vibration sensor 103 and the fixing base 101 facing the mounting base 106 is connected by adhesive or screws. When performing vibration testing on mechanical equipment, the electromagnet installed at the fixed base 101 is energized, so that the fixed base 101, carrying the vibration sensor 103, is firmly attached to the mechanical equipment to be tested. The vibration of the mechanical equipment is transmitted to the vibration sensor 103 through the fixed base 101, so that the vibration sensor 103 can collect the vibration of the mechanical equipment to be tested.

[0030] In this embodiment, the vibration sensor 103 can be a piezoelectric ceramic vibration sensor, a capacitive vibration sensor, or an electromagnetic vibration sensor. Vibration sensors of these types have the advantage of low resistance to electromagnetic interference. The vibration sensor 103 and the backend controller or mobile terminal are connected via a transmission chip, thereby enabling more convenient collection of detection results.

[0031] like Figure 1 , 5 As shown, the switch for the electromagnet at the control base 101 is located at the handle 105 of the support rod 104, which facilitates the operator to turn on the electromagnet. At the same time, the power supply for the electromagnet is also located at the handle 105 to reduce the load on the end of the support rod 104.

[0032] Example 2:

[0033] Based on Example 1, such as Figure 1 , 2 In the embodiment shown, in order to make the distance between the fixed seat 101 and the end of the claw structure 102 adjustable in its natural state, so that the fixed seat 101 can better adhere to the surface of the mechanical equipment with unevenness at the detection point, a through groove 110 is provided at the claw structure 102, and the connecting ends of each elastic connector 107 and the claw structure 102 are movably connected to the through groove 110 by fasteners.

[0034] The fastener can be configured as a screw 108 and a first nut 109. The end of the screw 108 is provided with a clamping piece 111. One end of the elastic connector 107 is connected to the clamping piece 111. In practical use, the screw 108 passes through the through groove 110, causing the clamping piece 111 to contact the inner wall of the claw-shaped structure 102. When the first nut 109 is tightened, the first nut 109 and the clamping piece 111 clamp the claw-shaped structure 102, thus fixing the fastener at the claw-shaped structure 102. To facilitate tightening the first nut 109, a rotor nut can be used.

[0035] Example 3:

[0036] Based on Example 2, such as Figure 2 As shown, in order to prevent relative movement between the fastener and the claw structure 102 when the first nut 109 is tightened, an anti-slip structure is provided at the part where the clamping piece 111 and the claw structure 102 come into contact.

[0037] The anti-slip structure is composed of mutually cooperating toothed plates or mutually cooperating anti-slip pads respectively disposed on the surfaces of the clamping plate 111 and the claw-shaped structure 102 that come into contact with each other.

[0038] Example 4:

[0039] Based on any of the embodiments in Examples 1-3, in order to reduce the vibration when the fixing seat 101 is attracted to the surface of the mechanical equipment to be tested, a buffer pad is provided on the surface of the fixing seat 101 and the mechanical equipment to be tested on the side of contact.

[0040] The cushioning pad can be made of silicone or rubber.

[0041] Example 5:

[0042] Based on any of the embodiments in Examples 1-4, during use, when the claw-shaped structure 102 contacts the mechanical device to be tested, in order to increase the friction between the end of the claw-shaped structure 102 and the mechanical device to be tested, so that the force applied at the handle 105 of the support rod 104 and the friction cooperate, making the claw-shaped structure 102 more reliably contact the mechanical device to be tested, an anti-slip pad is provided at the end of the claw-shaped structure 102 that contacts the mechanical device to be tested. The anti-slip pad can also be made of silicone or rubber.

[0043] Example 6:

[0044] Based on any of the embodiments in Examples 1-5, such as Figure 1 , 3As shown in Figure 4, to allow the mounting base 106 to achieve a larger bending angle, the mounting base 106 is connected to the end of the support rod 104 via a universal bracket. One optional form of the universal bracket includes a connecting rod 112 and two clips 114. One end of the connecting rod 112 is provided with a ball head 118, and the other end of the connecting rod 112 is used to connect to the mounting base 106. Each of the clips 114 is provided with a groove 116 that matches the surface of the ball head 118, and the groove 116 is used to contact the ball head 118. Each clip 114 is provided with a through hole 117 for the connecting rod 112 to pass through. The through hole 117 and the groove 116 at that clip 114 are concentrically arranged. The other clip 114 is connected to the end of the support rod 104. During the specific assembly of the Wanxiang support, the connecting rod 112 is first passed through the through hole 117 of a card 114, and the other card 114 is connected to the card 114, so that the grooves 116 of the two cards 114 hold the ball head 118 of the connecting rod 112. Finally, the two cards 114 are fixed by bolts 113 and second nuts 115.

[0045] In this embodiment, a spring is fitted at each bolt 113, with one end of the spring abutting against the nut and the other end abutting against the card 114. In actual use, the spring provides elasticity, ensuring that the clamping force of the bolt 113 and the second nut 115 on the two cards 114 is within a suitable range, thereby preventing the clamping force of the two cards 114 from being too large or too small.

[0046] The above-described embodiments are merely preferred embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be covered within the protection scope of this utility model.
