[0053] Example 1:

[0054] A ton bag folding and shearing device, see Figure 1 , comprising a shearing table 1.

[0055] See Figure 1 and Figure 2 , the front side of the shearing table 1 is provided with a fixed cutter 2. The fixed cutter 2 comprises a fixed seat 21 and a fixed cutter 22, the fixed seat 21 is welded and fixed on the front side wall of the shearing table 1, the top of the fixed seat 21 is provided with a fixed groove 211, the fixed cutter 22 is inserted into the fixed groove 211, the front side wall of the fixed seat 21 is threadedly connected with a plurality of fixed bolts 212, one end of the fixed bolt 212 extending into the fixed groove 211 abuts against the front side of the fixed cutter 22, so that the fixed cutter 22 is clamped between the rear side wall of the fixed groove 211 and the fixed bolt 212, that is, the fixed cutter 22 can be fixed on the fixed seat 21. After the fixed bolt 212 is screwed outward away from the fixed cutter 22, the fixed cutter 22 can be taken out of the fixed groove 211, which facilitates replacement after the fixed cutter 22 is damaged.

[0056] See Figure 1 and Figure 2 , the front right end of the shearing table 1 is welded and fixed with a hinge seat 12. The hinge seat 12 is hingedly connected with a movable cutter 3. The movable cutter 3 comprises a movable seat 31 and a movable cutter 32, the right end of the movable seat 31 is hingedly connected with the hinge seat 12, the bottom of the movable seat 31 is provided with a movable groove 311, the movable cutter 32 is inserted into the movable groove 311, the front side of the movable seat 31 is threadedly connected with a plurality of movable bolts 312, one end of the movable bolt 312 extending into the movable groove 311 abuts against the front side of the movable cutter 32, so that the movable cutter 32 is clamped between the rear side wall of the movable groove 311 and the movable bolt 312, that is, the movable cutter 32 can be fixed on the movable seat 31. After the movable bolt 312 is screwed outward away from the movable cutter 32, the movable cutter 32 can be taken out of the movable groove 311, which facilitates replacement after the movable cutter 32 is damaged.

[0057] See Figure 1The device further comprises a portal frame 4, which is arranged above the shearing table 1.

[0058] Referring to Figure 1 The portal frame 4 is provided with a shearing driving mechanism 5. The shearing driving mechanism 5 comprises a telescopic rod 51 and a sliding seat 52. The telescopic rod 51 can be an oil cylinder or an air cylinder or an electric push rod. The upper end of the telescopic rod 51 is fixedly installed at the middle part of the portal frame 4. The lower end of the telescopic rod 51 is rotatably connected with the sliding seat 52. The sliding seat 52 is provided with a dovetail groove. Figure 2 The top of the movable seat 31 is provided with a sliding rail 313, which is an integral structure with the movable seat 31. The dovetail groove and the sliding rail 313 are in sliding fit.

[0059] The principle of the shearing driving mechanism 5 driving the movable cutter 3 to ascend and descend is as follows:

[0060] When the telescopic rod 51 is extended, the lower end of the telescopic rod 51 pushes the sliding seat 52 to move downward, and the sliding seat 52 pushes the movable seat 31 to move downward. Since the right end of the movable seat 31 is hingedly connected with the hinge seat 12, when the movable seat 31 moves downward, the movable seat 31 rotates downward around the hinge seat 12 as the center, and the movable seat 31 drives the movable cutter 32 to rotate downward together, so that the movable cutter 32 cooperates with the fixed cutter 22 to cut the ton bag cloth 10. In the process of the movable seat 31 rotating downward, the sliding rail 313 at the top of the movable seat 31 and the sliding seat 52 adaptively slide relative to each other. Conversely, when the telescopic rod 51 is shortened, the movable cutter 32 moves upward away from the fixed cutter 22.

[0061] Referring to Figure 8 The front side of the portal frame 4 is provided with a conveying mechanism 6. Referring to Figure 3 and Figure 4 The conveying mechanism 6 comprises conveying frames 61, roller shafts 62, gears 63 and a conveying motor 64. The conveying frames 61 are provided with two, one of which is fixedly installed at the left end of the top front side of the portal frame 4, and the other of which is fixedly installed at the right end of the top front side of the portal frame 4. The roller shafts 62 are provided with two, which are arranged between the two conveying frames 61. The two roller shafts 62 are rotatably connected with the conveying frames 61 through bearings. A conveying gap 621 is arranged between the two roller shafts 62, which is used for the ton bag cloth 10 to pass through. The right end of each roller shaft 62 is fixedly installed with a gear 63, and the gears 63 at the right ends of the two roller shafts 62 are in meshing engagement. The left end of one roller shaft 62 is fixedly connected with the output end of the conveying motor 64, and the conveying motor 64 is fixedly installed on the left conveying frame 61.

[0062] The principle of the conveying mechanism 6 conveying the ton bag cloth 10 downward is as follows:

[0063] The ton bag cloth 10 from the previous process passes through the conveying gap 621. The conveying motor 64 is started, the conveying motor 64 drives the first roller shaft 62 to rotate, the gear 63 at the right end of the first roller shaft 62 drives the gear 63 at the right end of the second roller shaft 62 to rotate in the opposite direction, so that the two roller shafts 62 rotate in opposite directions, continuously conveying the ton bag cloth 10 clamped between the two roller shafts 62 to the rear, and because the ton bag cloth 10 sags under its own gravity, as the two roller shafts 62 continuously convey, the ton bag cloth 10 is conveyed downward.

[0064] Referring to Figure 8 , the left side of the gantry 4 is provided with a linear drive mechanism 7. Referring to Figure 5 , the linear drive mechanism 7 includes a support frame 71, a lead screw 72, a guide rod 73, a linear motor 74, and a moving seat 75. The support frame 71 is provided with two, both of which are arranged on the left side of the gantry 4, the lead screw 72 and the guide rod 73 are arranged between the two support frames 71, the front and rear ends of the lead screw 72 are both rotatably connected to the support frame 71 through bearings, and the front and rear ends of the guide rod 73 are both welded and fixed to the support frame 71. The linear motor 74 is a servo motor, which is fixedly installed on one of the support frames 71, and the output end of the linear motor 74 is fixedly connected to the rear end of the lead screw 72. The moving seat 75 is not only threadedly connected to the lead screw 72, but also slidably connected to the guide rod 73. The moving seat 75 is fixedly installed with the folding rod 8.

[0065] The principle of the linear drive mechanism 7 driving the folding rod 8 to move linearly in the front-rear direction is as follows:

[0066] When the linear motor 74 drives the lead screw 72 to rotate forward, the moving seat 75 drives the folding rod 8 to move linearly from front to back; when the linear motor 74 drives the lead screw 72 to rotate in the opposite direction, the moving seat 75 drives the folding rod 8 to move linearly from back to front. When the moving seat 75 drives the folding rod 8 to move linearly in the front-rear direction, the folding rod 8 passes between the fixed knife 22 and the movable knife 32.

[0067] The working principle of the first embodiment is as follows:

[0068] (1) Referring to Figure 12 , the conveying mechanism 6 is started, the conveying mechanism 6 conveys the ton bag cloth 10 to the rear, the ton bag cloth 10 sags under its own gravity, and as the conveying mechanism 6 continuously conveys, the ton bag cloth 10 extends downward in the vertical direction. When the vertical distance between the lower end of the ton bag cloth 10 and the cutting edge of the fixed knife 22 meets the required length after folding, the conveying mechanism 6 pauses.

[0069] (2) Referring to Figure 13, the linear driving mechanism 7 is started, the linear driving mechanism 7 drives the folding rod 8 to move backward, the folding rod 8 pushes the middle part of the ton bag cloth 10 to pass between the fixed cutter 22 and the movable cutter 32; in this process, the conveying mechanism 6 is started, the conveying speed of the conveying mechanism 6 is greater than the speed of the linear driving mechanism 7 driving the folding rod 8 to move, so that the length of the ton bag cloth 10 located below the folding rod 8 is basically unchanged; with the pushing of the folding rod 8 and the conveying of the conveying mechanism 6, referring to Figure 14 , the ton bag cloth 10 is gradually folded and conveyed to the rear of the shearing table 1. When the lower end of the ton bag cloth 10 slides through the fixed cutter, the linear driving mechanism 7 and the conveying mechanism 6 are closed.

[0070] (3) referring to Figure 14 and Figure 10 and Figure 11 , the shearing driving mechanism 5 is started, the shearing driving mechanism 5 drives the movable cutter 3 to move downward, the movable cutter 32 in the movable cutter 3 approaches the fixed cutter 22, until the movable cutter 32 and the fixed cutter 22 cooperate to shear the folded part and the subsequent part of the ton bag cloth 10, referring to Figure 15 .

[0071] (4) referring to Figure 16 , the folded ton bag cloth 10 is stacked on the fork arm of the forklift, and a certain number of folded ton bag cloths 10 are sent to the next sewing process. In the sewing process, referring to Figure 17 , the worker can easily find the two shearing ends of the folded ton bag cloth 10 and sew them together to form a side seam, so as to obtain a cylindrical ton bag, and then sew the bag bottom and the lifting belt of the ton bag cloth 10.

[0072] Through the above working principle, it can be known that the embodiment 1 has the following effects:

[0073] Firstly, the folding and shearing device of the embodiment 1 can fold the ton bag cloth 10 first, and then shear the folded ton bag cloth 10 and the subsequent cloth, so as to obtain the folded ton bag cloth 10. The length of the shearing table 1 meets the folded ton bag cloth 10, which is beneficial to reduce the floor area and improve the space utilization rate of the factory.

[0074] Secondly, the folding and shearing device of the embodiment 1 realizes the folding and shearing of the ton bag cloth 10, without the need for manual folding by the worker, which is beneficial to reduce the labor intensity of the worker.

[0075] Thirdly, because the embodiment 1 can shear to obtain the folded ton bag cloth 10, when the folded ton bag cloth 10 is transported to the sewing process, the worker can easily find the shearing end from the folded ton bag cloth 10, and the two shearing ends of the ton bag cloth 10 are sewn as a side seam, which is beneficial to improve the sewing efficiency.

[0076] Embodiment 2:

[0077] The embodiment 2 is further improved on the basis of the embodiment 1:

[0078] In the embodiment 2, referring to Figure 8 and Figure 9 , the adjusting mechanism 9 is further included. Referring to Figure 6 and Figure 7 , the adjusting mechanism 9 includes an adjusting plate 91, an adjusting frame 92, an adjusting seat 93 and an adjusting bolt 94. The adjusting plate 91 is located below the conveying mechanism 6. The left and right ends of the adjusting plate 91 are both provided with the adjusting frame 92. The two adjusting frames 92 are fixed on the ground. The two adjusting frames 92 are both provided with a vertical hole 921. The left and right ends of the adjusting plate 91 are both in sliding fit with the vertical hole 921 in the vertical direction. The left and right ends of the adjusting plate 91 are both welded with the adjusting seat 93. The two adjusting seats 93 are located between the two adjusting frames 92. The two adjusting seats 93 are both threadedly connected with the adjusting bolt 94. The adjusting bolt 94 is in abutment with the adjusting frame 92.

[0079] Referring to Figure 6 and Figure 7 , the adjusting frame 92 is provided with a scale 922. The scale 922 gradually increases from top to bottom. From top to bottom, the scale 922 is 0cm, 50cm, 150cm, 200cm, 250cm, 300cm, 350cm, 400cm, 450cm and 500cm respectively. The uppermost scale 922 is flush with the height of the blade of the fixed knife 22.

[0080] The working principle of the embodiment 2 is as follows:

[0081] When the lower end of the ton bag cloth 10 reaches the upper surface of the adjusting plate 91, it indicates that the vertical distance between the lower end of the ton bag cloth 10 and the blade of the fixed knife 22 has met the required length after folding. At this time, the conveying of the ton bag cloth 10 by the conveying mechanism 6 can be paused. The linear driving mechanism 7 is started to drive the folding rod 8 to push the ton bag cloth 10 backward. Then the conveying mechanism 6 is restarted to gradually fold the ton bag cloth 10.

[0082] Through the above process, it can be known that the adjusting plate 91 is convenient for workers to know whether the ton bag cloth 10 reaches the required length for folding, and is convenient to use.

[0083] The height of the adjusting plate 91 is adjustable. Before adjustment, the adjusting bolt 94 needs to be unscrewed from the adjusting frame 92. During adjustment, the adjusting plate 91 can slide up and down in the vertical hole 921 of the adjusting frame 92. After the position of the adjusting plate 91 is adjusted, the adjusting bolt 94 needs to be screwed to abut on the adjusting frame 92. The use flexibility is further improved, which is convenient to use.

[0084] It will be apparent to those skilled in the art that various modifications and variations can be made to the present application without departing from the spirit or scope of the application. Thus, it is intended that the present application cover modifications and variations of this application provided they come within the scope of the appended claims and their equivalents.
