DETAILED DESCRIPTION

[0028] Figures 1 to 9The present invention provides a schematic structural diagram of an embodiment of a strip bag stacking and boxing device, comprising a frame 1, a feeding rack 2, a gathering mold 3, a material shifting mechanism 4, a material pushing mechanism 5, and a stacking and boxing mechanism 6. The gathering mold 3 is arranged on the frame 1, and the feeding rack 2 is reciprocatingly arranged on the frame 1. The material shifting mechanism 4 and the material pushing mechanism 5 are respectively arranged on the feeding rack 2, and the material shifting mechanism 4 is located above the gathering mold 3, and the material pushing mechanism 5 is located at the output end of the gathering mold 3. The stacking and boxing mechanism 6 is arranged on the frame 1, and the stacking and boxing mechanism 6 is located at the output end of the gathering mold 3. The gathering mold 3 is used to narrow the distance between the strip bags 47, the material shifting mechanism 4 is used to shift the strip bags 47 on the gathering mold 3 to the stacking and boxing mechanism 6, the stacking and boxing mechanism 6 is used to stack the strip bags 47 into two layers, and the material pushing mechanism 5 is used to push the two layers of strip bags 47 in the stacking and boxing mechanism 6 to the packaging box 48.

[0029] During operation, the strip bag 47 is transported to the gathering mold 3 through the equipment of the previous process (not shown in the figure), the material-digging mechanism 4 blocks the rear end of the strip bag 47, and the feeding rack 2 drives the material-digging mechanism 4 to move toward the output end of the gathering mold 3, so that the material-digging mechanism 4 diverts the strip bag 47 toward the output end of the gathering mold 3. In the process of the material-digging mechanism 4 diverting the strip bag 47 to the output end of the gathering mold 3, the feeding rack 2 drives the material-digging mechanism 4 to divert the strip bag 47 for a distance, and then the material-digging mechanism 4 is lifted up and does not contact the strip bag 47, and then the feeding rack 2 drives the material-digging mechanism 4 to move the strip bag 47 to the output end of the gathering mold 3. The material mechanism 4 moves toward the input end close to the folding mold 3, thereby causing the material diverting mechanism 4 to retreat, and then the material diverting mechanism 4 blocks the rear end of the strip bag 47, and the feeding rack 2 drives the material diverting mechanism 4 to move toward the output end close to the folding mold 3, and so on and so forth until the strip bag 47 in the folding mold 3 is transferred to the stacking box packaging mechanism 6, and the strip bag 47 is stacked into a double layer. While the feeding rack 2 drives the material diverting mechanism 4 to move toward the output end close to the folding mold 3, the feeding rack 2 drives the pushing mechanism 5 to push the stacked double-layer strip bag 47 into the packaging box 48.

[0030] Linear slide rails 7 are respectively provided on both sides of the frame 1, and sliders 8 are provided on the linear slide rails 7. The sliders 8 are connected to the feeding rack 2, and both sides of the feeding rack 2 are fixedly connected to the transmission mechanism.

[0031] The transmission mechanism includes a bracket 9, a material-feeding servo motor 10, a transmission belt 11, an active roller 12, a passive roller 13, and a connecting plate 14. The active roller 12 and the passive roller 13 are respectively rotatably arranged on the bracket 9, the material-feeding servo motor 10 is connected to the active roller 12, the transmission belt 11 is sleeved on the active roller 12 and the passive roller 13, the connecting plate 14 is fixed on the transmission belt 11, and the connecting plate 14 is fixedly connected to the two sides of the feeding rack 2 through the support plate.

[0032] When the feed rack 2 drives the material dispensing mechanism 4 to reciprocate in the length direction of the folding mold 3, the material dispensing servo motor 10 drives the active roller 12 to drive the transmission belt 11 to rotate, and the transmission belt 11 drives the connecting plate 14 to drive the feed rack 2 to move. During the movement of the feed rack 2, the feed rack 2 moves along the linear slide rail 7 through the slider 8. Through the linear slide rail 7 and the slider 8, the feed rack 2 can smoothly perform forward or backward reciprocating motion.

[0033] The gathering mold 3 includes a gathering limit groove 15 and multiple strip bag conveying grooves 16. The multiple strip bag conveying grooves 16 are arranged side by side, and the distance between two adjacent strip bag conveying grooves 16 gradually decreases from the input end to the output end. The gathering limit groove 15 is located at the output end of the multiple strip bag conveying grooves 16.

[0034] The number of the strip bag conveying troughs 16 is set according to production needs, and this embodiment does not limit the number of the strip bag conveying troughs 16 .

[0035] The strip bag 47 is placed in the strip bag conveying trough 16. The material shifting mechanism 4 and the feeding frame 2 cooperate with each other to shift the strip bag 47 from the input end of the strip bag conveying trough 16 to its conveying end, then shift it from the output end of the strip bag conveying trough 16 to the gathering and limiting slot 15, and finally shift the strip bag 47 from the gathering and limiting slot 15 to the stacking and boxing mechanism 6. By gradually reducing the distance between two adjacent strip bag conveying troughs 16 from the input end to the output end, the distance between the two strip bags 47 is reduced. Then, the gathering and limiting slot is used to further reduce the distance between the strip bags 47, so that the strip bags 47 are neatly arranged side by side.

[0036] The material diverting mechanism 4 includes a material diverting rod 17, a material diverting plate 18, and a material diverting cylinder 19. There are multiple material diverting rods 17, and the multiple material diverting rods 17 are spaced apart along the conveying direction of the strip bag conveying trough 16. Each material diverting rod 17 is rotatably arranged on the feeding rack 2, and a material diverting plate 18 is respectively provided on each material diverting rod 17.

A transmission rod 21 is connected between the swing arms 20 of two adjacent material diverting rods 17, and the transmission rod 21 is connected to the driving end of the material diverting cylinder 19 through a fixed block 22.

[0037] When the material-dipping mechanism 4 is diverting, the material-diverting cylinder 19 contracts, and the material-diverting cylinder 19 drives the transmission rod 21 to move through the fixed block 22. The transmission rod 21 drives the swing arms 20 at both ends to swing, and the swing arms 20 drive the material-diverting plate 18 to rotate. The material-diverting rod 17 drives the material-diverting plate 18 vertically downward and blocks the rear end of the strip bag 47. When the feeding rack 2 drives the material-diverting mechanism 4 to retract, the material-diverting cylinder 19 extends, and the material-diverting cylinder 19 drives the transmission rod 21 to drive the swing arm 20 to swing. The swing arm 20 drives the material-diverting plate 18 to rotate, and the material-diverting plate 18 vertically downward and leaves the strip bag 47 without contacting the strip bag 47.

[0038] The pushing mechanism 5 includes a pushing servo motor 23 and a pushing plate 24. The pushing servo motor 23 is arranged on the feeding rack 2.

[0039] The push plate 24 includes a connecting block 25, an upper material rod 26, and a lower material rod 27. The connecting block 25 is connected to the output end of the push servo motor 23. The upper material rod 26 and the lower material rod 27 are respectively arranged on the connecting block 25, and the upper material rod 26 and the lower material rod 27 are distributed parallel to each other.

[0040] The stacking cartoning mechanism 6 includes a mounting frame 28, a cartoning servo motor 29, a linear transmission structure 30, a mounting plate 31, and a stacking mold 32. The cartoning servo motor 29 is arranged on the mounting frame 28, and the output end of the cartoning servo motor 29 is connected to the linear transmission structure 30. The mounting plate 31 is arranged on the linear transmission structure 30, and the stacking mold 32 is arranged on the mounting plate 31. The cartoning servo motor 29 drives the stacking mold 32 to rise and fall through the linear transmission structure 30, so that the stacking mold 32 is adapted to the height of the retraction limit slot 15.

[0041] The linear transmission structure 30 includes a linear guide rail 33, a slide 34, a ball screw 35, and a support seat 36. There are two linear guide rails 33, and the two linear guide rails 33 are respectively set on the mounting frame 28. Each linear guide rail 33 is respectively provided with a slide 34. The ball screw 35 is connected to the output end of the box loading servo motor 29. The support seat 36 is mounted on the ball screw 35 through a nut assembly, and the support seat 36 and the slide 34 are fixedly connected. The mounting plate 31 is set on the support seat 36.

[0042] The stacking mold 32 includes an upper template 37, a middle template 38, and a lower template 39 arranged in sequence from top to bottom. The inner sides of the upper template 37, the middle template 38, and the lower template 39 are connected to each other. An upper accommodating cavity 41 is formed between the upper template 37 and the middle template 38, and a lower accommodating cavity 42 is formed between the middle template 38 and the lower template 39. The outer side of the middle template 38 is connected to a middle baffle 43, and the outer side of the lower template 39 is connected to a lower baffle 44. There is an upper channel 45 between the middle baffle 43 and the bottom of the upper template 37, and the upper channel 45 is for the upper material rod 26 to pass through. There is a lower channel 46 between the bottom of the middle template 38 and the lower baffle 44, and the lower channel 46 is for the lower material rod 27 to pass through.

[0043] When the material shifting rod 17 pushes the strip bag 47 in the closing limit slot 15 into the stacking cartoning mechanism 6, the cartoning servo motor 29 drives the ball screw 35 to rotate, and the ball screw 35 rotates to drive the nut assembly to rise and fall along the ball screw 35, and the nut assembly drives the support seat 36 and the mounting plate 31 and the stacking mold 32 arranged on the mounting plate 31 to rise and fall, so that the upper accommodating cavity 41 or the lower accommodating cavity 42 of the stacking mold 32 is adapted to the height of the closing limit slot 15, so that the material shifting plate 18 shifts the strip bag 47 in the closing limit slot 15 into the upper accommodating cavity 41 and the lower accommodating cavity 42, thereby realizing that the strip bag 47 is stacked into two layers, and the transmission structure drives the feeding rack 2 During the return process, the pushing servo motor 23 drives the pushing plate 24 to rotate to a vertical state. When the feeding rack 2 returns to its original position and the pushing plate 24 is located at the rear end of the stacking mold 32, the pushing servo motor 23 drives the pushing plate 24 to rotate to a horizontal state, so that the upper material rod 26 of the pushing plate 24 corresponds to the upper accommodating cavity 41, and the lower material rod 27 corresponds to the lower accommodating cavity 42. Then the transmission structure drives the feeding rack 2 to move forward, driving the upper material rod 26 and the lower material rod 27 to move forward at the same time. The upper material rod 26 pushes the strip bag 47 in the upper accommodating cavity 41 into the packaging box 48, and at the same time, the lower material rod 27 pushes the strip bag 47 in the upper accommodating cavity 41 into the packaging box 48 (as shown in FIG.

The two groups of folding molds 3 are arranged side by side on the feeding rack 2. The output end of each group of folding molds 3 corresponds to a group of pushing mechanism 5, and each group of pushing mechanism 5 corresponds to a group of stacking molds 32.

[0045] By arranging two groups of the retracting mold 3, the pushing mechanism 5, and the stacking mold 32, two boxes of strip bags 47 can be packed into boxes at the same time, thereby further improving work efficiency.

[0046] The stacking mold 32 of this embodiment has two accommodating cavities, an upper accommodating cavity 41 and a lower accommodating cavity 42, which can stack two layers of strip bags 47.
