DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] In order to solve the technical problem that the conveying device lacks real-time detection and real-time cleaning of damaged salt bags, the present invention provides a salt bag conveying device for a salt production line, which can realize real-time monitoring and automatic processing of damaged salt bags.

[0018] See also Figure 1 , Figure 1 It is a structural schematic diagram of a salt bag conveying device for a salt production line in one embodiment of the present invention. The salt bag conveying device for a salt production line includes a conveying mechanism 1, a detection mechanism 2, a picking mechanism 3 and a cleaning mechanism 4.

[0019] The conveying mechanism 1 is used for conveying the salt bags 5 .

[0020] The detection mechanism 2 is arranged above the conveying mechanism 1 and is used to detect the salt content on the surface of the salt bag 5 on the conveying mechanism 1 .

[0021] The picking mechanism 3 is arranged above the conveying mechanism 1 and is used to pick out and store the salt bags 5 on the conveying mechanism 1 whose salt content is greater than a preset content.

[0022] The cleaning mechanism 4 is disposed above the conveying mechanism 1 and is used to remove residual salt on the conveying mechanism 1 .

[0023] When in use, the packaged salt bags 5 are continuously transported through the conveying mechanism 1. As the salt bags 5 move on the conveying mechanism 1, the detection mechanism 2 starts to work. The detection mechanism 2 is located above the conveying mechanism 1 and performs non-contact scanning on the surface of the salt bags 5 being transported to detect the salt content on the surface. The detection mechanism 2 can accurately and quickly identify the salt bags with excessive residual salt on the surface. Once the detection mechanism 2 finds that the salt content on the surface of a salt bag 5 exceeds the preset threshold, the picking mechanism 3 is immediately triggered. The picking mechanism 3 can quickly and accurately pick out the damaged salt bags from the conveying mechanism and transfer them to the designated storage area for subsequent processing. After picking out the damaged salt bags, the cleaning mechanism 4 is immediately started. The cleaning mechanism 4 thoroughly removes the residual salt on the conveying mechanism 1. This step ensures the continuous cleaning of the conveying mechanism, prevents cross-contamination of salt, maintains the hygiene of the production environment, and improves the quality of the final product.

[0024] In one embodiment, see Figure 1 The conveying mechanism 1 includes a conveying bracket 11, a driving pulley 12, a driven pulley 13, a conveying belt 14 and a conveying drive. The driving pulley 12 and the driven pulley 13 are rotatably arranged at the two ends of the conveying bracket 11, respectively. The conveying belt 14 is closed, and its two ends are respectively wound around the driving pulley 12 and the driven pulley 13 to form a closed-loop conveying path. The conveying drive is connected to the driving pulley 12. When the conveying drive is started, it will drive the driving pulley 12 to rotate, and then drive the conveying belt 14 and the driven pulley 13 to rotate together, so as to realize the continuous transportation of the salt bag 5. In this embodiment, the conveying drive is a stepping motor.

[0025] In one embodiment, see Figure 1 The salt bag conveying device for the salt production line also includes a mounting bracket 6, which is fixed above the conveying mechanism 1 to provide a stable mounting base for other components. The detection mechanism 2 is an infrared spectrometer 21, which is mounted on the mounting bracket 6, with its detection end facing the salt bag 5 on the conveying belt 14, and is used to detect the salt content on the surface of the salt bag 5 on the conveying mechanism 1. The specific detection principle is: the structure of salt molecules and plastic molecules of packaging bags are different, and different characteristic spectra are presented in the reflection spectrum of the infrared spectrometer 21. According to the difference in these characteristics, salt molecules and plastic molecules of packaging bags can be distinguished. The infrared spectrometer 21 detects the molecular components at multiple nodes in an area at one time, thereby obtaining the salt content.

[0026] In one embodiment, see Figure 1 and Figure 2 The picking mechanism 3 includes a longitudinal moving cylinder 31, a vertical moving cylinder 32, a suction cup 33, a vacuum pump 34 and a collecting bucket 38. The cylinder body of the longitudinal moving cylinder 31 is fixed on the mounting bracket 6, and its length direction is horizontal and perpendicular to the conveying direction of the conveying mechanism 1. The output shaft of the longitudinal moving cylinder 31 is fixedly connected to the cylinder body of the vertical moving cylinder 32. The length direction of the vertical moving cylinder 32 is vertically arranged, and its output shaft is fixedly connected to the suction cup 33 to realize the movement of the suction cup in the vertical direction. The inlet of the vacuum pump 34 is connected to the suction cup 33. When the suction cup 33 moves to one side of the conveying mechanism 1, the collecting bucket 38 is located below the suction cup 33. When the vacuum pump 34 is started, negative pressure is formed inside the suction cup, which can firmly adsorb the damaged salt bag 5.

[0027] In this embodiment, the salt bags 5 are placed on the conveying mechanism 1 at equal intervals. When the infrared spectrometer 21 detects that the salt content on the surface of a salt bag 5 exceeds the standard, the conveying mechanism 1 continues to convey until the salt bag 5 moves to the bottom of the suction cup 33 (the moving distance is determined by the number of rotations of the stepping motor), and then the suction cup 33 is driven downward by the vertical moving cylinder 32 until the suction cup 33 contacts the surface of the salt bag 5, and then the vacuum pump 34 is turned on, and negative pressure is formed inside the suction cup, which can firmly absorb the damaged salt bag 5, and then the vertical moving cylinder 32 lifts the salt bag 5, and then the longitudinal moving cylinder 31 drives the salt bag 5 to move perpendicular to the conveying direction until it reaches the side of the conveying mechanism 1, and then the vacuum pump 34 is deflated, and the salt bag 5 is separated from the suction cup 33 under the action of gravity and falls into the collection bucket 38 below, and the damaged salt bag 5 is collected by the collection bucket 38 for subsequent processing.

[0028] In one embodiment, see Figure 1 and Figure 2 The inlet of the vacuum pump 34 is connected to the suction cup 33 via a first hose 35 .

[0029] In one embodiment, see Figure 1 and Figure 2 The picking mechanism 3 also includes a connecting rod 36, the output shaft of the longitudinal moving cylinder 31 is fixedly connected to one end of the connecting rod 36, and the other end of the connecting rod 36 is fixedly connected to the cylinder body of the vertical moving cylinder 32.

[0030] In one embodiment, see Figure 1 and Figure 2 The picking mechanism 3 also includes a fixing block 37 , which is fixed on the mounting bracket 6 , and the cylinder body of the longitudinal moving cylinder 31 is fixed on the fixing block 37 .

[0031] In one embodiment, see Figure 1 and Figure 3 The cleaning mechanism 4 includes a dust collecting head 41, a lifting drive cylinder 42 and a dust collecting mechanism 43. The dust collecting head 41 is arranged above the conveying mechanism 1, and is used to absorb the salt remaining on the conveying mechanism. The cylinder body of the lifting drive cylinder 42 is fixed on the mounting bracket 6, and its output shaft is connected to the dust collecting head 41, and is used to realize the movement of the dust collecting head in the vertical direction. The dust collecting mechanism 43 is connected to the dust collecting head 41, and is used to collect and process the absorbed salt.

[0032] In one embodiment, see Figure 1 and Figure 3 The dust suction mechanism 43 includes a waste box 431, a second hose 432, a filter cover 433 and a suction pump 434. An air inlet and an exhaust port are provided at the upper end of the waste box 431. One end of the second hose 432 is connected to the air inlet, and the other end is connected to the dust suction head 41 to form a dust suction channel. The filter cover 433 is arranged at the opening of the exhaust port to filter out the absorbed salt particles to prevent them from entering the suction pump and causing damage. The inlet of the suction pump 434 is connected to the exhaust port. When the suction pump is started, negative pressure can be generated to send the salt particles absorbed by the dust suction head 41 into the waste box 431 through the second hose 432.

[0033] In this embodiment, when the infrared spectrometer 21 detects that the salt content on the surface of a salt bag 5 exceeds the standard, the conveying mechanism 1 continues to convey until the salt bag 5 moves to the bottom of the suction cup 33. At this time, the salt bag 5 is picked out and stored by the picking mechanism 3, and then the conveying mechanism 1 continues to convey until the original position of the salt bag 5 moves to the bottom of the filter cover 433. At this time, the filter cover 433 is driven downward by the lifting drive cylinder 42 until it is in contact with the conveying belt 14, and then the suction pump 434 is started. The suction pump 434 creates a negative pressure environment in the waste box 431, and the salt on the conveying belt 14 is sucked into the waste box 431. The filter cover 433 can prevent the salt from being discharged from the exhaust port, thereby protecting the suction pump 434.

[0034] In one embodiment, see Figure 1 and Figure 3 The dust suction mechanism 43 further includes a third hose 435 , one end of which is connected to the exhaust port, and the other end of which is connected to the inlet of the suction pump 434 . In order to better understand the present invention, the following Figures 1 to 3 The technical solution of the present invention is described in detail: when in use, the packaged salt bag 5 is continuously conveyed through the conveying mechanism 1. As the salt bag 5 moves on the conveying mechanism 1, the detection mechanism 2 starts to work. The detection mechanism 2 is located above the conveying mechanism 1 and performs non-contact scanning on the surface of the salt bag 5 being conveyed to detect the salt content on its surface. The salt bag with too much residual salt on the surface can be accurately and quickly identified. Once the detection mechanism 2 finds that the salt content on the surface of a salt bag 5 exceeds the preset threshold, the picking mechanism 3 is immediately triggered. The picking mechanism 3 can quickly and accurately pick out the damaged salt bag from the conveying mechanism and transfer it to a designated storage area for subsequent processing. After picking out the damaged salt bag, the cleaning mechanism 4 is immediately started. The cleaning mechanism 4 thoroughly removes the residual salt on the conveying mechanism 1. This step ensures the continuous cleaning of the conveying mechanism, prevents cross-contamination of salt, maintains the hygiene of the production environment, and improves the quality of the final product.
