[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Reference Manual Attached Figure 1 , Figure 2 and Figure 3 As shown, the automatic stacking and conveying device for bagging calcium carbonate powder comprises: a workbench 1; The clamping adjustment mechanism 2 includes a first motor 3 placed on the workbench 1, the output shaft of the first motor 3 extends to the turntable 4 at the bottom of the workbench 1, the protrusions around the turntable 4 and the first slider 5 are connected by a swing rod 6, the first slider 5 is connected with an inclined groove 7 along the length direction of the workbench 1, and a U-shaped plate 8 is fixedly connected to the first slider 5; wherein, both ends of the swing rod 6 are installed on the first slider 5 and the protrusion by a rotation connection, the top of the inner wall of the U-shaped plate 8 is movably connected with a clamping plate 10 by a compression spring 9, the top of the workbench 1 is connected with a first cylinder 11 through a side plate, the piston rod at the bottom of the first cylinder 11 extends to the pull rope 12 and the telescopic pressure plate 13 in turn, the pull rope 12 is distributed around the piston rod, and one end of the pull rope 12 is installed on the fixed ring 14 by a traction connection, the bottom of the fixed ring 14 and the clamping plate 10 are connected by a movable rod 15, and the outer wall edge of the movable rod 15 is provided with a movable opening placed on the U-shaped plate 8.

[0024] A clamping adjustment mechanism 2 is set. After the first motor 3 is started, it can drive the turntable 4 to rotate. With the rotation connection of the swing rod 6, the first slider 5 can be moved to the four sides of the bag body, and the clamping mechanism can be moved to the corresponding position according to the size of the bag body. During the start-up of the first cylinder 11, not only can the elastic restoring force of the compression spring 9 be used to move the clamp 10 downward for clamping, but also the clamp 10 can be pulled outward in cooperation with the process of the clamp 10, so that the clamp 10 can move freely while effectively clamping the bag body. Moreover, during the downward movement of the telescopic pressing plate 13 on the first cylinder 11, the pressing action can be effectively realized, thereby adjusting the flatness of the bag body. Moreover, the pressing plate is of telescopic design, and the length of the pressing plate can be adjusted according to the size of the bag body. It has strong applicability and can effectively improve the utilization rate of the device.

[0025] Specifically, the inclined grooves 7 around the workbench 1 provide space for the movement of the first slider 5, and at the same time facilitate the clamping mechanism to clamp and fix the bag body around. At the same time, the pull rope 12 is installed on the fixed ring 14 by a traction connection. Such a setting method can facilitate the installation and disassembly work between the structural parts, and the movable opening on the U-shaped plate 8 can allow the movable rod 15 to move up and down accordingly when subjected to traction. Compared with the up and down movement of the splint 10 directly driven by the positioning rod, the setting of the pull rope 12 can not only ensure that the bag body is clamped and fixed by the splint 10, but also ensure that when the splint 10 is fixed and clamped, it moves outward or inward synchronously. In this way, it can adapt to the adaptive clamping and fixing work of bags of different sizes, which is not achievable by the existing technical solutions and technical effects.

[0026] refer to Figure 3 , Figure 6 and Figure 7 The automated stacking and conveying device for bagging calcium carbonate powder also includes a conveying and stacking mechanism 16, which includes a conveying line 17 disposed at one end of the workbench 1. The conveying line 17 is mounted on a frame and extends in a preset direction to carry and convey the bag.

[0027] A second motor 18 is fixedly installed on the frame, and the output shaft of the second motor 18 extends to the first conveyor belt 19 and the second conveyor belt 20 in sequence. One end of the second conveyor belt 20 is connected to the first rotating wheel 21 for transmission. One end of the first rotating wheel 21 passes through the cover and extends to the first bevel gear 22. Both ends of the outer wall of the first bevel gear 22 are meshed and transmitted with second bevel gears 24 fixed on the reciprocating screw 23. The second bevel gear 24 is correspondingly spirally driven with a second slider 25. A scraper 27 placed on the top surface of the first collecting box 26 is installed on the second slider 25 through a bracket. Notches 28 are provided at both ends and the center of the top surface of the first collecting box 26 and are fixed to the frame. The scraper 27 is connected with a slide groove along the length direction of the first collecting box 26. A second collecting box 29 placed on the first collecting box 26 is provided below the notch 28. The second collecting box 29 is a pull-out movable design, and one end of the outer wall of the second collecting box 29 is integrally formed with a handle connected.

[0028] A conveying and cleaning mechanism is provided. When the bag is transported on the conveyor line 17 and particles fall into the first collecting box 26, the second motor 18 is started and drives the first rotating wheel 21 to rotate through the second conveyor belt 20. Under the action of the gear meshing transmission, the reciprocating screws 23 at both ends can be rotated. Through the spiral transmission, the scrapers 27 at both ends can move back and forth horizontally and clean the impurities and concentrate them to the slot 28. Moreover, the second collecting box 29 can quickly process and clean the impurities through the pull-out movable design. Through the coordinated setting of the cleaning mechanism, the particles generated during long-distance transportation can be automatically and centrally processed. The automation efficiency is high, and the cleanliness of the working environment is effectively guaranteed.

[0029] First, when the distance of the conveyor line 17 is too long, when the powder particles in the bag fall into the second collecting box 29, it is inconvenient to clean the second collecting box 29 because the distance of the second collecting box 29 is also relatively long. Therefore, the present invention is designed with a cleaning mechanism. When the second motor 18 is started, it can drive the rotation of the second conveyor belt 20 and transmit the power to the first bevel gear 22 of the first rotating wheel 21. Under the action of the gear meshing transmission, the rotational force in the Y-axis direction of the horizontal plane is converted into the rotational force in the X-axis direction, and the reciprocating screw 23 is rotated. Under the action of the spiral transmission, the scraper 27 on the second slider 25 can perform back and forth cleaning work.

[0030] In addition, the slots 28 on the first collecting box 26 are designed at both ends and the center position, so that the scraper 27 can cooperate with the impurities to be swept to the slots 28 at the two ends and the center position during the back and forth movement. In this way, the impurities can be collected in a centralized manner and then directly taken out through the second collecting box 29, which is convenient for personnel to operate.

[0031] A stacking mechanism is set up. After the second motor 18 is started, it can simultaneously drive the second rotating wheel 31 to rotate, and the lower sprocket 33 rotates. In cooperation with the upper sprocket 34, the chain 35 can be made to circulate in the annular groove 36, so that the L-shaped bending plate 37 at the center of the chain 35 can be driven to move synchronously. Since the opening of the L-shaped bending plate 37 is located on one side of the inclined plate 32, the bag body that has fallen can be effectively supported and connected, and multiple bag bodies can be effectively stacked and placed in layers, thereby ensuring the orderliness of the bag body placement and facilitating the personnel's taking work.

[0032] refer to Figure 1 , Figure 8 and Fig. 9 One end of the first conveyor belt 19 is transmission-connected to a second rotating wheel 31 placed on a third collection box 30. The third collection box 30 and the conveyor line 17 are connected via an inclined plate 32. One end of the second rotating wheel 31 extends to a lower sprocket 33 on the inner wall of the third collection box 30. A retaining ring is installed at the other end. The lower sprocket 33 and the upper sprocket 34 are transmission-connected via a chain 35. An annular groove 36 placed on the third collection box 30 is provided on the outer wall edge of the chain 35, and an L-shaped bending plate 37 with an opening toward one side of the inclined plate 32 is fixedly installed on the chain 35.

[0033] Specifically, the L-shaped bending plate 37 is fixedly connected to the center position of each point when the chain 35 rotates in the annular groove 36, so that when the L-shaped bending plate 37 rotates with the chain 35, its own position will not move relative to the L-shaped bending plate 37. At the same time, the L-shaped bending plate 37 can always support and connect the sliding bag body, and during the sliding process, the protrusion on one side can be used for limiting protection to prevent sliding.

[0034] refer to Figure 1 , Figure 4 and Figure 5 A clamping cavity connected to the four end surfaces of the bag body is formed between the clamping plate 10 and the U-shaped plate 8, and the bottom of the first motor 3 is fixedly connected to the workbench 1 through a crossbeam.

[0035] Specifically, the crossbeam itself is set in an I-shaped configuration, which reduces the material cost and provides a good support effect for the first motor 3. When the first cylinder 11 drives the piston rod to move downward, the distance of the pull rope 12 becomes shorter, thereby loosening it. Under the elastic recovery action of the compression spring 9, the bag body is clamped and fixed, so that the pull rope 12 can adjust the tightness during the process of the bag body clamping and moving outward, so that the first slider 5 can move normally. The automated stacking and conveying device for bagging calcium carbonate powder also includes a second cylinder 38 placed on the top of the workbench 1, and one end of the piston rod on the second cylinder 38 is connected to the push plate 39.

[0036] refer to Fig.10The automatic stacking and conveying method of bagged calcium carbonate powder comprises the following steps: S1.1. Place the bag containing calcium carbonate powder on the workbench 1, start the first motor 3, and move the U-shaped plate 8 connected to the first slider 5 to the surroundings of the bag according to the different sizes of the bag, start the first cylinder 11 to move downward, and under the elastic recovery action of the compression spring 9, the telescopic pressing plate 13 moves downward and clamps the bag; S1.2, step S1.1 After the first cylinder 11 is started, the retractable pressing plate 13 can press the bag body, so that the bag body maintains a corresponding flatness, and at the same time the first slider 5 moves outward, so that the bag body can be further tightened and adjusted around, so that the retractable pressing plate 13 can effectively press and adjust the bag body; S1.3, after the pressing is completed, the second cylinder 38 is started and pushes the bag onto the conveyor line 17, and the second motor 18 is started to collect the foreign particles generated during the conveying of the bag, and at the same time, the bag can be automatically conveyed to the third collection box 30; S1.4. Under the driving action of the chain 35, the L-shaped bending plate 37 can perform a fixed-point circular motion and can achieve orderly stacking of the bags.

[0037] The entire stacking and conveying method is reasonably designed, with good automation effect, strong integration performance, and simple manual operation. It can effectively and quickly adjust the flatness of the bag, thereby effectively utilizing space resources and preventing the bag from slipping, greatly improving the safety of the device placement, and placing the bags in layers to prevent disordered stacking.
