[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.
[0027] See Figures 1-12 The present invention provides a bag unloading and cleaning machine, including a bag unloading machine 1 and a bag cleaning machine 2. The bag unloading machine 1 is inclined and the bag cleaning machine 2 is horizontal. A transition roller 3 is provided between the head of the bag unloading machine 1 and the tail of the bag cleaning machine 2. A dust collection hood 4 is provided on the outside of the bag unloading machine 1 and the bag cleaning machine 2. A blower mechanism 5 is provided on the dust collection hood 4 near the head of the bag cleaning machine 2. A first dust collection port 6 and a second dust collection port 7 are respectively provided on the dust collection hood 4 near the middle of the bag unloading machine 1 and the bag cleaning machine 2.
[0028] In implementation, the bag unloading machine 1 adopts a belt conveyor structure; the first dust collection port 6 and the second dust collection port 7 can be connected to common dust collection equipment, such as a bag filter dust collector, for dust collection. The blower mechanism 5 has been patented by our company (application number 2024218155114), and its specific structure will not be described in detail here. The bag cleaning machine 2 adopts a roller conveyor structure including a drive roller and a driven roller. The drive roller is directly driven by a geared motor, and the driven rollers are transmitted to the drive roller and adjacent driven rollers through a chain and sprocket structure.
[0029] Dust curtains 8 are installed on the dust collection hood 4 at the inlet near the tail of the bag unloading machine 1 and at the outlet near the head of the bag cleaning machine 2.
[0030] The dust collection hood 4 adopts a segmented structure, including a first dust collection hood 9 covering the outside of the bag unloading machine 1 and a second dust collection hood 10 covering the outside of the bag cleaning machine 2. The first dust collection hood 9 and the second dust collection hood 10 are sealed together. Both the first dust collection hood 9 and the second dust collection hood 10 can be equipped with inspection doors for easy maintenance.
[0031] Both the first dust collection hood 9 and the second dust collection hood 10 are equipped with a bag blockage detection mechanism 11. The bag blockage detection mechanism 11 includes a detection shaft 12 that is rotatably connected to the first dust collection hood 9 and the second dust collection hood 10. A detection swing rod 13 is provided on the detection shaft 12. The detection swing rod 13 includes a trigger rod 14 that extends upward to the top surface of the first dust collection hood 9 and the second dust collection hood 10 and a bag blocking rod 15 that extends downward to the upper side of the bag unloading machine 1 and the bag cleaning machine 2. A tactile switch is provided on the top surface of the first dust collection hood 9 and the second dust collection hood 10 at a position opposite to the end of the trigger rod 14. Specifically, the length of the bag-blocking rod 15 is greater than the length of the trigger rod 14, so that the overall weight of the bag-blocking rod 15 is greater than the overall weight of the trigger rod 14. In this way, when no cement bags pass by, the trigger rod 14 is lifted upward under the action of weight and contacts the tactile switch, thus triggering the tactile switch. When a cement bag passes by, the cement bag pushes the bag-blocking rod 15 and causes the trigger rod 14 to swing downward and separate from the tactile switch. The tactile switch is then disconnected, thus confirming that a cement bag has passed by.
[0032] When performing bag blockage detection, since the time it takes for the cement packaging bag to be transported to the bag blockage detection mechanism 11 after the previous filling process is fixed, the completion of the previous filling process can be used as the starting point for timing. If the bag stop bar 15 is not activated after the set time, causing the trigger bar 14 to swing downward and separate from the tactile switch, then a bag blockage is determined to have occurred. For example, if the timing starts after the completion of the previous filling process, and under normal circumstances the cement packaging bag needs 20 seconds to be transported to the position of the bag blockage detection mechanism 11 to activate the bag stop bar 15, then the tactile switch can be set to remain activated after 25 seconds to determine if a bag blockage has occurred. In practice, both the bag unloading machine 1 and the bag cleaning machine 2 are equipped with bag blockage detection mechanisms 11. The location of the bag blockage detection mechanism 11 is determined according to the location in the actual production environment where bag blockage is likely to occur. This utility model does not limit the specific location.
[0033] A cleaning mechanism 16 is provided inside the second dust collection hood 10. The cleaning mechanism 16 includes adjustment mechanisms 17 arranged opposite each other on the sides of the second dust collection hood 10. A cleaning shaft 18 is arranged between the adjustment mechanisms 17, and brush bristles 19 are provided on the cleaning shaft 18. The cleaning shaft 18 and the drive roller in the bag cleaning machine 2 can be driven by the transmission pulley 20 and the transmission belt. During the rotation of the cleaning shaft 18, the brush bristles 19 drive the cleaning machine 2 to clean the surface of the cement packaging bag.
[0034] The adjustment mechanism 17 includes a guide rail 21 mounted on the side of the second dust collection hood 10, a slider 22 mounted on the guide rail 21, and a cleaning shaft 18 positioned between the two opposing sliders 22. A support plate 23 is mounted at one end of the guide rail 21, and an adjustment screw 24 is connected to the slider 22. The adjustment screw 24 passes through the support plate 23, and adjustment nuts 25 are threaded onto both sides of the adjustment screw 24 on the support plate 23. By adjusting the two adjustment nuts 25, the distance between the cleaning shaft 18 and the drive roller is changed, thereby adjusting the tension of the drive belt.
[0035] The bag cleaning machine 2 adopts a roller conveying structure, wherein the roller includes connecting plates 26 arranged at intervals and opposite to each other, a main shaft 27 is inserted through the center of the connecting plates 26, and connecting rods 28 are evenly arranged between the connecting plates 26 and on the outer periphery of the main shaft 27. The connecting plates 26, the main shaft 27 and the connecting rods 28 form a cage structure, which is more conducive to the conveying of cement packaging bags than a single roller structure, and can also play a certain scraping role to clean the cement dust attached to the surface.
[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
