Those skilled in the art can easily understand the advantages and effects of the present invention based on the content disclosed in this specification. The present invention can also be implemented in other different ways, that is, various modifications and changes can be made without departing from the scope of the present invention.

[0026] The position descriptions such as up, down, left, and right in this embodiment are based on the orientations in the drawings and have no special meanings and are not intended to limit the scope of protection of the present utility model.

[0027] Example: An automatic filter bag conveying device, such as Figures 1 to 5 As shown, the conveying device includes a conveying frame 1 and a driving shaft 2, a driven shaft 3, a left conveyor belt 4, a right conveyor belt 5, two rear end guide positioning components 6, two front end guide positioning components 7, two side sensors 8 and a bottom sensor 9, which are arranged on the conveying frame. The driving shaft and the driven shaft are respectively located at both ends of the conveying frame, the left conveyor belt is sleeved on the left side of the driving shaft and the driven shaft, and the right conveyor belt is sleeved on the right side of the driving shaft and the driven shaft; the two side sensors are respectively located on both sides of the front end of the conveying frame, and the bottom sensor is located at the bottom of the conveying frame and aligned with the gap between the left conveyor belt and the right conveyor belt;

[0028] The two rear-end guide positioning assemblies are located on both sides of the rear end of the conveying frame, and the distance between the two in the width direction of the conveying frame can be adjusted; the two front-end guide positioning assemblies are located on both sides of the front end of the conveying frame, and the distance between the two in the width direction of the conveying frame can be adjusted;

[0029] One end of the driving shaft or the driven shaft is connected to a rotation driving mechanism 10 that can drive the driving shaft or the driven shaft to rotate.

[0030] In this embodiment, Figure 1 and Figure 5 As shown, the rear-end guide positioning assembly 6 and the front-end guide positioning assembly 7 each include a positioning side plate 61, a positioning block 62, a guide post 63, and a connecting plate 64. The lower end of the connecting plate is fixed to the side of the conveyor frame, the positioning block is fixed to the back of the positioning side plate, one end of the guide post is fixed to the positioning block, and the other end of the guide post passes through the upper end of the connecting plate and is able to slide. A fastener 65 passes through the through hole at the upper end of the connecting plate and abuts against the guide post, thereby fixing the guide post relative to the connecting plate. The distance between the two rear-end guide positioning assemblies and the two front-end guide positioning assemblies is adjusted according to the width of the filter bag 100. The specific process is: loosen the fasteners, move the guide post to drive the positioning side plate to the appropriate position, and then tighten the fasteners. The above adjustment process is convenient, fast, and easy to operate.

[0031] In this embodiment, Figure 5 As shown, the rear ends of the positioning side plates of the two rear guide positioning assemblies form guide bell mouths 66, and the rear ends of the positioning side plates of the two front guide positioning assemblies also form guide bell mouths 66. When the filter bag is placed or passes through, it plays a positioning and guiding role, and the guide bell mouths facilitate the smooth entry of the filter bag.

[0032] In this embodiment, the bottom sensor and the two side sensors are diffuse reflection laser sensors, and the sensor accuracy is relatively high.

[0033] In this embodiment, the bottom of the conveyor frame is equipped with support legs 11 and multiple connecting rods 12 for added strength. The bottom sensor is located in the middle of one of the connecting rods. The two-stage conveyor belt, left conveyor belt 4 and right conveyor belt 5, is used to enable the bottom sensor to detect whether the filter bag has been delivered to the correct position.

[0034] In this embodiment, the rotation drive mechanism is a speed-adjustable motor and a sprocket chain structure, which is a prior art and will not be described in detail. The speed-adjustable motor can be used to adjust the conveying speed of the filter bag.

[0035] The working principle and working process of this utility model:

[0036] Manually place the stacked or piled filter bags 100 at the rear end of the left and right conveyor belts. When unloading, the two rear end guide and positioning components play a guiding role to prevent the filter bags from being placed off-center. The filter bags then move with the left and right conveyor belts. During this process, the filter bags may be slightly offset. When they reach the front end of the conveyor frame, the front end guide and positioning components will guide and position them again to correct the offset. After the bottom sensor senses that the filter bags are in place, the conveying motors driving the left and right conveyor belts stop rotating, so the left and right conveyor belts stop conveying, and the signals can also be transmitted to subsequent processing steps. At the same time, the sensors on both sides will sense whether the filter bags are offset. If there is an offset, a signal will be transmitted, and manual intervention will be performed to correct the offset. After the above two guide positionings and the front end side sensor sensing to remind manual intervention, the accuracy of the final filter bag position can be guaranteed.

[0037] The distances between the two rear end guide positioning components and the two front end guide positioning components in the width direction of the conveying frame can be adjusted, so that the device can meet the conveying needs of filter bags of different specifications and improve the versatility of the device.

[0038] The above description is only an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure made by using the contents of the description and drawings of the present invention, or directly or indirectly used in other related technical fields, is also included in the patent protection scope of the present invention.
