DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] Specifically, when palletizing cartons, it is necessary to arrange several cartons in a row, and then arrange the cartons arranged in a row, and then stack them. In the prior art, when arranging cartons, a conveyor belt is generally used for conveying and arranging. When using a conveyor belt to convey and arrange cartons, after the conveyor belt is used to convey the carton to one end of the conveyor belt, the next carton is then placed in the conveyor belt for conveying until it is conveyed to one side of another carton, until multiple cartons are arranged in a row. During the conveying process, the conveyor belt is always in operation. Therefore, the lower end of the first carton placed on the upper end of the conveyor belt will be continuously rubbed by the conveyor belt, resulting in damage to the lower end of the carton. When using the present invention, a plurality of belt sections 12 are arranged at the upper end of the first workbench 1. After the carton is placed on the upper end of the belt 12, the first rotating wheel 121 is driven to rotate at the same time, driving the plurality of belt sections 12 to rotate, until the carton is conveyed to the belt 12 located on one side of the first workbench 1, and then The belt 12 on which cartons are placed is driven to stop rotating, and then the cartons are continuously conveyed to the upper end of the belt 12. When cartons are conveyed to the upper end of the belt 12, the belt 12 is then stopped rotating until cartons are placed on the belt 12 and arranged in a row. Then the U-shaped block 31 is driven to drive the second rectangular plate 33 to slide in the middle of the U-shaped frame 3 to one side of the belt 12. Then the third rectangular plate 36 is driven to move the cartons in a row at the upper end of the belt 12 to the upper end of the second rectangular plate 33 until multiple rows of cartons move to the upper end of the second rectangular plate 33. Then the cartons at the upper end of the second rectangular plate 33 are transferred to the upper end of the support plate 4. The U-shaped block 31 is driven to drive the second rectangular plate 33 to slide upward to stack multiple layers of cartons. Multiple belts 12 are set to convey and arrange multiple cartons. When the cartons are conveyed to the upper end of the corresponding belt 12, the corresponding belt 12 stops rotating to prevent friction at the lower end of the cartons when the cartons are conveyed and arranged.

[0032] like Figure 4-Figure 5 , Figure 7 As shown, the transmission component described in this embodiment also includes a second rotating wheel 122 that rotates at the lower end of the belt 12, and one side of the second rotating wheel 122 is rotatably connected to a first cylindrical block 127, and the first cylindrical block 127 is rotatably connected to one side of the rectangular groove 11, and the first cylindrical block 127 is provided with a shaped hole 1271 on one side close to the second rotating wheel 122, and the other side of the second rotating wheel 122 is fixedly connected to a second cylindrical block 128, and the middle part of the second rotating wheel 122 is slidably penetrated by a shaped bar 1221, and the shaped bar 1221 can slide into the shaped hole 1271, and the shaped bar 1221 slides through the middle part of the second cylindrical block 128.

[0033] Specifically, when conveying cartons, the second wheel 122 is driven to rotate by driving the first cylindrical block 127, and the rotation of the second wheel 122 drives the belt 12 to rotate, and at the same time drives the first wheel 121 to rotate. When a carton is conveyed to the upper end of the belt 12, the special-shaped strip 1221 is driven to completely slide out of the special-shaped hole 1271, so that the corresponding second wheel 122 stops rotating, and the corresponding belt 12 stops rotating, so that the carton remains stationary at the upper end of the belt 12, and then the cartons can be continuously conveyed to prevent friction on the conveyed cartons.

[0034] like Figure 4 As shown, in this embodiment, a sprocket 123 is fixedly connected to the outer side of the first cylindrical blocks 127 , and two adjacent sprockets 123 are driven by a chain 1231 .

[0035] Specifically, by setting the sprocket 123 and the chain 1231, several first cylindrical blocks 127 can be driven to rotate simultaneously. When the carton is conveyed normally, the special-shaped strip 1221 is located in the special-shaped hole 1271, so that the first cylindrical block 127 can drive the second rotating wheel 122 to rotate. When the carton is conveyed to the upper end of the belt 12, the corresponding special-shaped strip 1221 will slide out of the special-shaped hole 1271, so that the corresponding belt 12 stops rotating, and it will not affect the rotation of other belts 12.

[0036] like Figure 5 As shown, in this embodiment, an elastic component is provided between the two second rectangular blocks 125 in the same group of transmission components, and the elastic component includes a first telescopic rod 1252 fixedly connected between the two second rectangular blocks 125, and a first spring 1253 is sleeved on the outer side of the first telescopic rod 1252. Several of the first cylindrical blocks 127 rotate together and penetrate the waist-shaped bar 124 respectively, and the second cylindrical blocks 128 penetrate the waist-shaped bar 124 respectively, and the lower ends of the two waist-shaped bars 124 are fixedly connected to the first rectangular plate 1242 through the first rectangular block 1241.

[0037] Specifically, the first rectangular plate 1242 is driven to move downward through the first rectangular block 1241 to drive the waist-shaped bar 124, and the waist-shaped bar 124 drives the second rotating wheel 122 to move downward through the second cylindrical block 128 and the first cylindrical block 127. When the second rotating wheel 122 moves downward, it drives the two first rotating wheels 121 at the upper end to approach each other, and at the same time drives the first telescopic rod 1252 to contract, and at the same time squeezes the first spring 1253, so that the transmission length of the upper end of the belt 12 becomes shorter, and the transmission length of the belt 12 can be adjusted according to the size of the carton.

[0038] like Figure 5 As shown, in this embodiment, the second rectangular block 125 provided on one side of two adjacent groups of conveying components is fixedly connected by a fourth rectangular block 126, the lower end of the fourth rectangular block 126 is fixedly connected to a fifth rectangular block 1261, the upper end of the rectangular groove 11 is fixedly connected to a third rectangular bar 14, and the fifth rectangular block 1261 can slide on the upper end of the third rectangular bar 14.

[0039] Specifically, by fixing the second rectangular block 125 provided on one side of the two groups of transmission components through the fourth rectangular block 126, when the transmission length of the upper end of the belt 12 is adjusted, the fourth rectangular block 126 drives the fifth rectangular block 1261 to slide on the upper end of the third rectangular strip 14, so that the distance between the two belts 12 is always kept consistent.

[0040] like Figure 6 As shown, the upper end of the third rectangular bar 14 described in this embodiment is fixedly connected to the first cylindrical bar 13 through the first rectangular bar 131, and a plurality of second cylinders 133 are rotatably connected to the middle of the first cylindrical bar 13. The second cylinders 133 can slide on the outside of the first cylindrical bar 13, and baffles 132 are respectively fixedly connected to the middle of the second cylinders 133, and push plates 1321 are respectively slidably connected to one side of the baffles 132.

[0041] Specifically, after the carton is conveyed to the upper end of the belt 12, the second cylinder 133 located on one side of the carton is driven to rotate, driving the baffle 132 to the side of the carton. When all the cartons are conveyed to the upper end of the belt 12, the corresponding baffle 132 is rotated to the side of the carton, and then the push plate 1321 is driven at the same time to push the carton to the upper end of the first conveyor belt 16. The push plate 1321 and the baffle 132 are in a vertical state, which can ensure that the carton remains vertical when pushing the carton.

[0042] like Figure 6-Figure 7As shown, in this embodiment, the outer end of the second cylinder 133 is fixedly connected to the first gear 134, and the lower end of the first gear 134 is meshed with a rack 136, and the lower end of the rack 136 can slide on the upper end of the third rectangular bar 14 through the sixth rectangular block 1361, and the lower end of the rack 136 is fixedly connected to the second telescopic rod 1362, and the lower end of the second telescopic rod 1362 is fixedly connected to the L-shaped bar 1363, and the second cylindrical block 128 is slidably connected to the first cylinder 1281 on one side, and the inner side of the first cylinder 1281 is fixedly connected to one end of the special-shaped bar 1221 through the second spring 1282, and the first cylinder 1281 can slide on one side of the L-shaped bar 1363.

[0043] Specifically, after the carton is transferred to the upper end of the belt 12, the second cylinder 133 is driven to rotate, driving the baffle 132 to rotate to one side of the carton, and at the same time driving the first gear 134 to rotate, the first gear 134 drives the rack 136 to move, the rack 136 drives the L-shaped bar 1363 to move away from the second rotating wheel 122 through the second telescopic rod 1362, the L-shaped bar 1363 drives the special-shaped bar 1221 to move away from the second rotating wheel 122 through the first cylinder 1281, so that the special-shaped bar 1221 slides from the special-shaped hole 1271, so that the second rotating wheel 122 stops rotating, and the corresponding belt 12 stops rotating at the same time to prevent friction with the bottom of the carton.

[0044] like Figure 1 , Figure 3 As shown, in this embodiment, the second workbench 2 is fixedly connected to one side of the first workbench 1, a second conveyor belt 21 is installed on the upper end of the second workbench 2, and a first conveyor belt 16 is installed on one side of the upper end of the first workbench 1.

[0045] Specifically, a number of cartons are placed on the upper end of the second conveyor belt 21, and the second conveyor belt 21 conveys the cartons to the upper end of the belt 12 for arrangement. After the arrangement is completed, the push plate 1321 pushes the arranged cartons to the upper end of the first conveyor belt 16 for transportation.

[0046] Embodiment 2: Figure 2 As shown, compared with Example 1, another implementation of the present invention is: the U-shaped block 31 is respectively fixed with seventh rectangular blocks 311 on both sides inside, the seventh rectangular block 311 is slidably provided with a rectangular frame 32 on the outside, the two rectangular frames 32 are commonly fixed to the second rectangular plate 33, the upper ends of the rectangular frames 32 are respectively fixed with slide rails 321, the upper ends of the two slide rails 321 are commonly slidably provided with a fourth rectangular bar 322, one side of the fourth rectangular bar 322 is rotatably connected to the second cylindrical bar 34, and one side of the second cylindrical bar 34 is fixed to the third rectangular plate 36 through the eighth rectangular block 35.

[0047] Specifically, after the cartons in a row are pushed to the upper end of the second rectangular plate 33, the fourth rectangular bar 322 is driven to slide on the upper end of the slide rail 321 toward the side close to the first workbench 1, and then the second cylindrical bar 34 is driven to rotate through the eighth rectangular block 35 to drive the third rectangular plate 36 to rotate, so that the third rectangular plate 36 is positioned at one side of the carton, and then the fourth rectangular bar 322 is driven to drive the third rectangular plate 36 to move away from the first workbench 1, so that the carton moves to the side of the upper end of the second rectangular plate 33 away from the first workbench 1. When several cartons in a row are moved to the second After the rectangular plate 33 is at the upper end, the rectangular frame 32 is then driven to slide on the outside of the seventh rectangular block 311, and at the same time, the second rectangular plate 33 is driven to slide toward the side away from the first workbench 1, so that the second rectangular plate 33 is located at the upper end of the support plate 4, and then the fourth rectangular bar 322 is driven to slide toward the side close to the first workbench 1, so that the third rectangular plate 36 is located on one side of all cartons, and then the rectangular frame 32 is driven again to drive the second rectangular plate 33 to slide toward the side close to the first workbench 1. During sliding, since the third rectangular plate 36 is located on one side of the carton, the carton can remain at the upper end of the support plate 4.

[0048] like Figure 2 As shown, in this embodiment, a plurality of arc-shaped strips 331 are fixedly connected to the upper end of the second rectangular plate 33 .

[0049] Specifically, the upper ends of the plurality of arc strips 331 provided at the upper end of the second rectangular plate 33 are arc-shaped. When the carton slides to the upper end of the second rectangular plate 33, by providing the plurality of arc strips 331, the friction at the lower end of the carton can be reduced when the carton slides to the upper end of the second rectangular plate 33.

[0050] Working principle: by placing a plurality of cartons on the upper end of the second conveyor belt 21, the second conveyor belt 21 conveys the cartons to the upper end of the belt 12 for arrangement; after the cartons are placed on the upper end of the belt 12, a plurality of first cylindrical blocks 127 can be driven to rotate simultaneously by setting a sprocket 123 and a chain 1231; the first cylindrical block 127 drives the second rotating wheel 122 to rotate; the second rotating wheel 122 rotates to drive the belt 12 to rotate; by driving the multiple sections of the belt 12 to rotate, the cartons are conveyed to the upper end of the belt 12 located on one side of the first workbench 1;

[0051] Then, the second cylinder 133 is driven to rotate and drive the baffle 132 to rotate to one side of the carton, and at the same time, the first gear 134 is driven to rotate, and the first gear 134 drives the rack 136 to move, and the rack 136 drives the L-shaped bar 1363 to move away from the second rotating wheel 122 through the second telescopic rod 1362, and the L-shaped bar 1363 drives the special-shaped bar 1221 to move away from the second rotating wheel 122 through the first cylinder 1281, so that the special-shaped bar 1221 slides from the special-shaped hole 1271, so that the second rotating wheel 122 stops rotating, and at the same time, the corresponding belt 12 stops rotating to prevent friction with the bottom of the carton;

[0052] After the carton is conveyed to the upper end of the belt 12, the second cylinder 133 located at one side of the carton is then driven to rotate, driving the baffle 132 to one side of the carton. When all the cartons are conveyed to the upper end of the belt 12, the corresponding baffle 132 is rotated to one side of the carton, and then the push plate 1321 is driven at the same time to push the carton to the upper end of the first conveyor belt 16. The push plate 1321 and the baffle 132 are in a vertical state, which can ensure that the carton remains vertical when the carton is pushed.

[0053] After pushing the cartons in rows to the upper end of the second rectangular plate 33, the fourth rectangular bar 322 is driven to slide on the upper end of the slide rail 321 toward the side close to the first workbench 1, and then the second cylindrical bar 34 is driven to rotate through the eighth rectangular block 35 to drive the third rectangular plate 36 to rotate, so that the third rectangular plate 36 is positioned on one side of the cartons, and then the fourth rectangular bar 322 is driven to drive the third rectangular plate 36 to move away from the first workbench 1, so that the cartons are moved to the upper end of the second rectangular plate 33 away from the first workbench 1. When several cartons in rows are moved to the second rectangular plate 3 3, then drive the rectangular frame 32 to slide outside the seventh rectangular block 311, and at the same time drive the second rectangular plate 33 to slide away from the first workbench 1, so that the second rectangular plate 33 is located at the upper end of the support plate 4, then drive the fourth rectangular strip 322 to slide close to the first workbench 1, so that the third rectangular plate 36 is located on one side of all the cartons, and then drive the rectangular frame 32 again to drive the second rectangular plate 33 to slide close to the first workbench 1. During sliding, since the third rectangular plate 36 is located on one side of the carton, the carton can be kept at the upper end of the support plate 4.
