Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0027] like Figure 1-6As shown, the present application provides a single-layer woven bag double-covering machine, which is provided with a double-covering part, a transport part and a sewing part. The double-covering part includes a first bracket 1 and a second bracket 2. The first bracket 1 is provided with a clamping device, the clamping device includes two clamping assemblies, and the two clamping assemblies are jointly equipped with a shoe cover 3. The second bracket 2 is connected to a driving assembly, a double-covering device and a knife holder 4, and the knife holder 4 is connected to a cutting device. The double-covering device includes a connecting frame 5, which is connected to the driving assembly, and is connected to two first slide rails 6 on the connecting frame 5. The two first slide rails 6 are jointly equipped with two relatively arranged cover Double mechanism, each set of double mechanism includes a first slider 7 and a second slider 8 that slide with the two first slide rails 6 respectively, a connecting plate 9 is connected between the first slider 7 and the second slider 8, each first slider 7 is connected to a first rack plate 10, the connecting frame 5 is connected to a first cylinder 11, the output end of the first cylinder 11 is connected to one of the connecting plates 9, and the two connecting plates 9 are connected to a shoe plate 12. The height of the shoe plate 12 is consistent with the height of the shoe cover 3. The first gear 13 is rotatably connected to the bottom of the first cylinder 11, and the gear cooperates with the two first rack plates 10.

[0028] The shoe cover 3 is a double-layer bag, and the shoe cover 3 is a double-layer bag. After the double-layer bag is pulled out of the shoe cover 3, the single-layer bag on the rear side of the shoe cover 3 is pulled out of the shoe cover 3 by the shoe plate 12, and the shoe cover 3 is pulled out of the shoe cover 3 by the shoe plate 12. In the process of pulling the double-layer bag out of the shoe cover 3, the single-layer bag on the rear side of the shoe plate 12 is also pulled forward by a certain length of the shoe cover 3. Finally, the woven bag is cut by the cutting device, and then the above process is repeated again. The single-layer bag in front of the shoe cover 3 with a certain length is pushed into the shoe cover 3 by the shoe plate 12 again, realizing multiple double-layer bag work.

[0029] Here, the double mechanism is explained, in which the first slider 7 and the second slider 8 in one set of the double mechanism are respectively slidably matched with the two first slide rails 6, and the connecting plate 9 is connected between the first slider 7 and the second slider 8. The first slider 7 is connected to the first rack plate 10, and the first rack plate 10 cooperates with the first gear 13. The first slider 7 and the second slider 8 in the other set of the double mechanism are slidably matched with the first slide rail 6. However, only one first slider 7 and second slider 8 are connected to the same slide rail, that is, the two first rack plates 10 connected by the two first sliders 7 are respectively connected to two different first slide rails 6, and a first gear 13 cooperates with the two oppositely arranged first rack plates 10. Specifically, the first cylinder 11 drives the shoe plate 12 on a connecting plate 9 to move, thereby driving the relatively arranged first slider 7 and the second slider 8 to move to one side together. At this time, the first rack plate 10 connected to the first slider 7 also moves to one side, driving the first gear 13 to rotate. The rotation of the first gear 13 drives the other first rack plate 10 to move to the opposite side, thereby driving the other group of relatively arranged first sliders 7 and second sliders 8 to move to the opposite side, and then driving the shoe plate 12 on the other connecting plate 9 to move to the opposite side, thereby achieving the purpose of driving the two shoe plates 12 to move in opposite directions by the first cylinder 11. At the same time, the contraction of the cylinder can drive the two shoe plates 12 to move toward each other, shortening the distance between the two shoe plates 12.

[0030] Furthermore, in this embodiment, each clamping assembly includes two relatively arranged clamping blocks 14, and the two clamping blocks 14 are commonly connected to two clamping rods 15 and a pressure rod 16, the pressure rod 16 is arranged above the two clamping rods 15, and the shoe cover 3 is arranged between the two clamping rods 15 and the pressure rod 16. The shoe cover 3 is a double-layer structure with a hollow interior, and the shoe plate 12 can extend into the interior of the shoe cover 3. The lower layer and the upper layer of the shoe cover 3 are provided with upper guide wheels 17 at positions corresponding to the two clamping rods 15 and the pressure rod 16.

[0031] In the technical solution adopted in this embodiment, a clamping assembly is provided to position the shoe cover 3 and to clamp and guide the woven bag at the same time. Specifically, a pressure plate is used to press the top of the shoe cover 3, and the two clamping rods 15 are pressed against the bottom of the shoe cover 3. At the same time, the upper guide wheel 17 of the shoe cover 3 cooperates with the two clamping rods 15 to realize the positioning of the shoe cover 3. When the single-layer woven bag is put on the shoe cover 3, the upper guide wheel 17 can guide the movement of the woven bag, making it convenient for the woven bag to be put on the shoe cover 3. Specifically, the upper guide wheel 17 cooperates with the pressure rod 16 to fix the woven bag at the top of the shoe cover 3. Cooperating with the two clamping rods 15, the woven bag at the bottom of the shoe cover 3 is fixed to ensure the stability of the double-layer woven bag operation. The shoe cover 3 is a double-layer structure with a hollow interior. By extending the shoe plate 12 into the interior of the shoe cover 3, the single-layer woven bag reserved in front of the shoe cover 3 can be pushed into the shoe cover 3, and then the two-layer woven bag is stretched open by the double-layer mechanism to prevent the woven bag pushed into the shoe cover 3 from wrinkling. At the same time, the friction between the woven bag and the shoe plate 12 can be used to pull the double-layer woven bag out of the shoe cover 3, and at the same time, a certain length of single-layer woven bag is pulled out, which is convenient for the next double-layer operation.

[0032] Furthermore, in this embodiment, two second slide rails 18 are provided on the first bracket 1 at positions corresponding to the two clamping assemblies, and two third sliders 19 are provided on each second slide rail 18.

[0033] In the technical solution adopted in this embodiment, two third sliders 19 are provided to cooperate with the second slide rail 18, and the position of the side guide wheel 20 can be adjusted so that the position of the side guide wheel 20 corresponds to the position of the left and right sides of the shoe cover 3. The side guide wheels 20 are provided to facilitate putting a single-layer woven bag on the shoe cover 3 on the one hand, and on the other hand, to facilitate pulling the double-layer woven bag out of the shoe cover 3 when the double-layer work is completed, and at the same time facilitate the subsequent single-layer woven bag to be put on the shoe cover 3.

[0034] Furthermore, in this embodiment, the driving assembly includes a driving motor 21, an active roller 22 and a driven roller 23. The active roller 22 and the driven roller 23 are rotatably connected to the second bracket 2. The active roller 22 and the driven roller 23 are jointly equipped with a transmission belt 24, and the driving motor 21 is connected to the active roller 22 through the belt.

[0035] In the technical solution adopted in this embodiment, a driving component is provided to drive the shoe plate 12 to move toward the shoe cover 3, and the single-layer woven bag reserved outside the shoe cover 3 is pushed into the shoe cover 3 to realize the double-covering work. At the same time, after the double-covering work is completed, the shoe plates 12 move backwards to open the double-layer woven bag, and the double-layer woven bag on the shoe cover 3 is pulled out by the driving component. Specifically, the driving motor 21 drives the active roller 22 to rotate through the belt, thereby driving the transmission belt 24 and the driven roller 23 to rotate. It should be noted that the transmission belt 24 is connected to the connecting frame 5, thereby realizing the function of driving the entire double-covering device to move, and finally realizing the function of driving the shoe plate 12 to move back and forth.

[0036] Furthermore, in this embodiment, the transfer portion includes a third bracket 25, which is provided with a base plate 26, and a plurality of through grooves 27 are provided on the base plate 26.

The base plate 26 is also provided with a plurality of through holes 29. A transfer roller 30 is connected below the base plate 26, and a plurality of transfer wheels 31 are connected to the transfer roller 30. The plurality of transfer wheels 31 correspond to the positions of the through holes 29. The transfer roller 30 is connected to a transfer motor. The third bracket 25 is also connected to a rotating shaft 32, and a plurality of lower pressure wheels 33 are connected to the rotating shaft 32. The positions of the plurality of lower pressure wheels 33 correspond to the positions of the transfer wheels 31. The end of the rotating shaft 32 is connected to a pressing block 34. The third bracket 25 is provided with a second cylinder 35, and the output end of the second cylinder 35 is connected to the pressing block 34.

[0037] In the technical solution adopted in this embodiment, a plurality of through slots 27 are provided on the bottom plate 26, and suction devices are provided at positions corresponding to the plurality of through slots 27, so that the cut double-layer woven bag can be adsorbed on the bottom plate 26, which is convenient for the stability of the woven bag during the process of the clamping mechanism 28 clamping the double-layer woven bag. Specifically, the cut double-layer woven bag falls on the bottom plate 26, and the double-layer woven bag is adsorbed on the bottom plate 26 by the suction device, and then the clamping mechanism 28 in the chute 53 starts to move. It should be noted that the clamping mechanism 28 in the chute 53 is also realized by the cooperation of the motor and the moving belt, which will not be described in detail here. The clamping mechanism 28 moves along the direction of the slide 53 toward the double-layer woven bag until the clamping mechanism 28 moves to the far right, and then the clamping mechanism 28 clamps the double-layer woven bag and moves toward the sewing part. When the clamping mechanism 28 drives the woven bag to move and contact with multiple transfer wheels 31, the clamping mechanism releases the double-layer woven bag, and drives the transfer roller 30 to rotate through the transfer motor, thereby driving the multiple transfer wheels 31 to rotate. At the same time, the second cylinder 35 drives the pressing block 34 to move downward, driving the rotating shaft 32 and the lower pressing wheel 33 to press the double-layer woven bag downward, and with the cooperation of multiple transfer wheels 31 and the lower pressing wheel 33, the double-layer woven bag is sent into the sewing part.

[0038] It should be noted that the suction device used in this embodiment is existing technology. As long as it can play the suction function and adsorb the double-layer woven bag on the floor to maintain the stability of the double-layer woven bag, it will be sufficient. No further details will be given here.

[0040] In the technical solution adopted in this embodiment, the transport roller 37 is driven to rotate by the transport motor 40, thereby driving the transport belt 39 to move. At the same time, the cooperation of the driving gear 43 and the driven gear 44 drives the lower pressure roller 41 to rotate, thereby driving the lower pressure belt 42 to move. With the joint cooperation of the transport belt 39 and the lower pressure belt 42, the function of transporting the double-layer woven bag in the stitching part is realized.

[0049] The working principle of the present invention is as follows: first, a cylindrical single-layer woven bag with upper and lower openings is placed on the shoe cover 3, and a single-layer woven bag of double length is reserved at the front end of the shoe cover 3; then, the driving assembly drives the two shoe plates 12 to move toward the shoe cover 3 until the shoe plates 12 extend into the shoe cover 3 to a certain length. At this time, the shoe plates 12 push the single-layer woven bag reserved at the front end of the shoe cover 3 into the shoe cover 3; then, the first cylinder 11 is extended to drive the two shoe plates 12 to move back to each other, to open the double-layer woven bag; the driving assembly drives the two shoe plates 12 to move away from the shoe cover 3, to pull the double-layer woven bag out of the shoe cover 3 and to just above the bottom plate 26 of the third bracket 25; the third cylinder 51 drives the cutting knife 52 to move downward, The double-layer woven bag is cut and separated from the single-layer woven bag, and the double-layer woven bag falls onto the bottom plate 26.

After the double-layer woven bag enters the sewing part, the double-layer woven bag is driven to move under the joint action of the conveyor belt 39 and the lower pressure belt 42. The sewing device on one side of the sewing part sews the bottom end of the double-layer woven bag to realize the forming of the woven bag.

[0050] The utility model is provided with a double-covering part, specifically, through the design of the shoe cover 3 and the shoe plate 12, the shoe plate 12 pushes a single-layer woven bag of a certain length into the shoe cover 3, and then the shoe plate 12 is stretched to prevent the double-layer woven bag from wrinkling. At the same time, the double-layer woven bag can be pulled out of the shoe plate 12 through the friction between the shoe plate 12 and the double-layer woven bag, which is convenient for the subsequent double-covering of the woven bag, ensures the molding quality of the double-layer woven bag, and improves the double-covering efficiency of the woven bag; by providing a transfer part and a sewing part, the double-covered woven bag is transported and sewn, thereby realizing the assembly line production of the double-layer woven bag, and further improving the double-covering efficiency of the woven bag.
