Description

Technical Field

[0001] The utility model belongs to the technical field of belt deviation measurement, and more specifically, relates to a belt deviation warning device for tobacco conveying equipment. Background Art

[0002] Tobacco conveying equipment refers to mechanical equipment specifically designed for the tobacco industry, aiming to efficiently and smoothly convey tobacco raw materials or finished products. The belt is the main conveying component in the conveying equipment, which is used to carry and transfer tobacco. During the process of conveying tobacco, the belt may deviate due to various factors. For example, if the tobacco materials being conveyed are unevenly distributed and one side is too heavy, it is easy for the belt to deviate towards the heavier side;

[0003] Belt deviation may cause tobacco materials to spill, increasing losses. At the same time, the cleaning work will consume additional manpower and material resources. Moreover, long-term belt deviation will cause the rollers and idlers to bear additional axial forces, accelerating the wear of these components. Therefore, the prior art uses a warning device to give a warning after the belt deviates;

[0004] For example, the patent with the patent application number 202211602514.5 and the application date of December 5, 2022, discloses a belt deviation warning device for tobacco equipment. Although this warning device uses a magnetic switch to detect belt deviation through the displacement of a spring push rod, its sensitivity and accuracy may be limited. In the case of slight belt deviation or minor vibration, the displacement of the spring push rod may not be sufficient to trigger the magnetic switch, resulting in untimely warning or false alarm. And under the contact of the spring push rod, the belt still has the phenomenon of being worn. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the above-mentioned shortcomings of the prior art and provide a belt deviation warning device for tobacco conveying equipment with high precision and avoiding wear.

[0006] To solve the above technical problems, the utility model provides such a belt deviation warning device for tobacco conveying equipment, which includes a base, a warning device, a support column, and an infrared sensor.

The controller built in the infrared sensor is electrically connected to the warning device.

[0007] Preferably, it further includes a clamping assembly. The clamping assembly clamped on the support column is provided on the infrared sensor. The infrared sensor is installed on the support column through the clamping assembly, and the installation height of the infrared sensor on the support column is adjusted by the clamping assembly.

[0008] Preferably, the clamping assembly includes a clamping block 1, a screw and a clamping block 2. The upper side of the infrared sensor is connected to a clamping block 1 suitable for contacting and cooperating with the pillar. A screw is rotatably provided on the clamping block 1, and the screw is threadedly connected to a clamping block 2 that is slidably provided on one side of the clamping block 1.

[0009] Preferably, it also includes an infrared signal receiver and an infrared signal transmitter. The upper and lower ends of the pillar are respectively provided with an infrared signal receiver and an infrared signal transmitter. The infrared signal receiver and the infrared signal transmitter are respectively located on the upper and lower sides of the belt. The infrared signal receiver has a built-in controller, and the built-in controller of the infrared signal receiver is electrically connected to the early warning device.

[0010] Preferably, it also includes a slider and a bidirectional screw rod. Sliders are slidably provided at the upper and lower ends of the pillar. The infrared signal receiver and the infrared signal transmitter are respectively connected to the upper and lower sliders. A bidirectional screw rod is rotatably provided on the pillar.

[0011] Preferably, there are two pillars, which are rotationally symmetrically arranged with the belt as the center, and both pillars are provided with infrared sensors, infrared signal transmitters and infrared signal receivers.

[0012] Preferably, the base includes a sliding sleeve and a sliding rod slidably arranged on the sliding sleeve, and the two pillars are respectively installed on the sliding sleeve and the sliding rod.

[0013] Preferably, a mounting rib is also included, and a row of threaded holes 1 arranged left and right are opened on the sliding sleeve and the sliding rod.

The lower end of the pillar is connected to the mounting rib, and the mounting rib is opened with threaded holes 2 suitable for corresponding to the threaded holes 1.

[0014] On the basis of overcoming the shortcomings of the prior art, the utility model can achieve the following beneficial effects:

[0015] 1. When the belt deviates to a certain distance, no matter the belt is tilted or shifted as a whole, the infrared sensor will control the warning device to emit sound and light through the built-in controller to perform a warning operation of belt deviation. The measurement accuracy is high, and the working belt never contacts the infrared sensor to avoid damage to the belt and infrared sensor due to friction.

[0024] In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. The technical solutions of the present utility model will be clearly and completely described below with reference to the drawings. It should be noted that the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] A tobacco conveying equipment belt deviation warning device, as Figure 1 and Figure 2As shown in the figure, it includes a base 1, a warning device 02, a support column 2, and an infrared sensor 3. The upper side of the base 1 is provided with a warning device 02 and a support column 2 on one side of the belt 01. An infrared sensor 3 with a built-in controller is installed on the support column 2. The infrared sensor 3 corresponds to the side of the belt 01 to be suitable for measuring the distance from the edge of the belt 01. The controller built in the infrared sensor 3 is electrically connected to the warning device 02. Within the range where the infrared sensor 3 is aligned with the belt 01 and maintains an appropriate distance, it can work effectively, measure the distance from the belt 01, and feedback it to the built-in controller. When the belt 01 runs off track by a certain distance, whether the belt 01 is tilted or translated as a whole, the infrared sensor 3 will control the warning device 02 to emit sound and light through the built-in controller to perform the warning operation for the belt 01 running off track. The measurement accuracy is high, and the working belt 01 never contacts the infrared sensor 3, avoiding damage to the belt 01 and the infrared sensor 3 due to friction.

[0026] As Figure 2 shown in the figure, it further includes a clamping assembly 4. The infrared sensor 3 is provided with a clamping assembly 4 clamped on the support column 2. The infrared sensor 3 is installed on the support column 2 through the clamping assembly 4. The clamping assembly 4 adjusts the installation height of the infrared sensor 3 on the support column 2. By loosening the clamping assembly 4, the position of the infrared sensor 3 on the support column 2 can be adjusted, so as to adjust the height of the infrared sensor 3 according to the height of the belt 01. It has strong adaptability. After adjustment, the clamping assembly 4 can be fixed to the support column 2.

[0027] As Figures 2 - 4 shown in the figure, the clamping assembly 4 includes a first clamping block 41, a screw 42, and a second clamping block 43. The upper side of the infrared sensor 3 is connected with a first clamping block 41 suitable for contacting and cooperating with the support column 2. A screw 42 is rotatably arranged on the first clamping block 41. A second clamping block 43 slidably arranged on one side of the first clamping block 41 is threadedly connected to the screw 42. Rotating the screw 42 makes the second clamping block 43 approach the first clamping block 41, so that the second clamping block 43 cooperates with the first clamping block 41 to clamp on the support column 2, thereby installing the infrared sensor 3 on the support column 2, and the installation height of the infrared sensor 3 can be adjusted as needed to accurately correspond to the belt 01 for measurement.

[0028] As Figure 3As shown in the figure, it further includes an infrared signal receiver 52 and an infrared signal transmitter 51. The upper and lower ends of the support column 2 are respectively provided with an infrared signal receiver 52 and an infrared signal transmitter 51. The infrared signal receiver 52 and the infrared signal transmitter 51 are respectively located on the upper and lower sides of the belt 01. The infrared signal receiver 52 is built-in with a controller, and the controller built-in in the infrared signal receiver 52 is electrically connected to the warning device 02. When the belt 01 is working normally, the signal emitted by the infrared signal transmitter 51 will be blocked by the belt 01. When the belt 01 runs off track and cannot block the signal emitted by the infrared signal transmitter 51, the infrared signal receiver 52 will receive the signal emitted by the infrared signal transmitter 51. Then the infrared signal receiver 52 will control the operation of the warning device 02 through the built-in controller. In this way, on the basis of the measurement in the parallel direction by the infrared sensor 3, the infrared signal receiver 52 and the infrared signal transmitter 51 are also used for measurement in the vertical direction to ensure the warning effect.

[0029] As Figure 3 and Figure 5 shown in the figure, it further includes a slider 53 and a bidirectional lead screw 54. The upper and lower ends of the support column 2 are both slidably provided with sliders 53. The infrared signal receiver 52 and the infrared signal transmitter 51 are respectively connected to the upper and lower sliders 53. The bidirectional lead screw 54 is rotatably provided on the support column 2. The upper and lower sliders 53 are respectively threadedly connected to the upper and lower ends of the bidirectional lead screw 54. Rotate the bidirectional lead screw 54 to make the bidirectional lead screw 54 drive the infrared signal receiver 52 and the infrared signal transmitter 51 to move away from or close to each other through the two sliders 53, so as to be able to adjust the distance between the infrared signal receiver 52 and the infrared signal transmitter 51 according to the situation, ensure the normal progress of the belt 01 running-off track warning operation, and have strong adaptability.

[0030] As Figure 2 shown in the figure, there are two support columns 2, and the two support columns 2 are rotationally symmetrically arranged with the belt 01 as the center. Infrared sensors 3, infrared signal transmitters 51 and infrared signal receivers 52 are all provided on the two support columns 2. The two infrared sensors 3 are respectively close to the input end and the output end of the belt 01, and the accuracy of the measurement of the belt 01 is increased by using the two infrared sensors 3. The same applies to the infrared signal transmitter 51 and the infrared signal receiver 52.

[0031] As Figure 2 shown in the figure, the base 1 includes a sliding sleeve 11 and a sliding rod 12 slidably arranged on the sliding sleeve 11. The two support columns 2 are respectively installed on the sliding sleeve 11 and the sliding rod 12, so that the sliding sleeve 11 and the sliding rod 12 slide towards each other to adjust the distance between the two support columns 2 and the belt 01, thereby adjusting the distance between the two infrared sensors 3 and the belt 01.

[0032] AsFigure 2 As shown, it further includes an installation rib plate 20. A row of threaded holes 1 arranged left and right are formed on both the sliding sleeve 11 and the sliding rod 12. The arrangement direction of the threaded holes 1 is perpendicular to the sliding direction of the sliding sleeve 11 and the sliding rod 12. The lower end of the support column 2 is connected with the installation rib plate 20. Threaded holes 2 adapted to the corresponding threaded holes 1 are formed on the installation rib plate 20, so that the threaded holes 2 on the installation rib plate 20 correspond to different threaded holes 1, and then screws are used for installation, whereby the support column 2 can be installed at different positions, thereby further improving the adaptability.

[0034] It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, quantity increases or decreases, improvements and substitutions can still be made. Therefore, based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative labor belong to the scope of protection of the present invention.
