[0012] In summary, the beneficial effects of the present utility model are as follows:
[0013] 1. The present utility model adds a turning structure to the conveying device, enabling the valve pocket to directly meet the front and back requirements required by the next processing step during the process of being sent out from the previous operation, so as to meet the processing requirements of the valve pocket for the next process, reducing an independent manual turning process, simplifying the processing steps of the valve pocket, improving the processing efficiency of the valve pocket, and providing convenience for the user's use.
[0014] 2. Through the settings of the supporting rod and the convex platform, the supporting rod is used to lift the valve pocket when turning the valve pocket to prevent the valve pocket from falling off the first turning frame or the second turning frame, ensuring the normal progress of the turning work. The convex platform is used to provide a fulcrum for the valve pocket during the turning process, preventing the valve pocket from moving randomly or slipping off the first turning frame and the second turning frame during the turning process, ensuring the normal progress of the turning work, and providing convenience for the user's work.
[0015] 3.

In addition, the height of the sliding block can be flexibly adjusted according to the thickness of the conveyed material to meet the actual processing needs. Specifically, when the user rotates the adjusting screw, the sliding block and the adjusting screw are threadedly connected. Therefore, when the adjusting screw is rotated, the sliding block will move up in the sliding cavity, and vice versa. In this way, when the sliding block moves and adjusts, the pressure roller will also move and adjust accordingly. In this way, the distance between the pressure roller and the conveying roller can be adjusted to meet the conveying needs of materials of different thicknesses, providing convenience for the user's work.

Specific implementation mode
[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Figures 1-4 Embodiment
[0026] A valve pocket conveying device with a turning function includes a frame 1. One side of the bottom of the frame 1 is fixedly installed with a mounting bracket 2. The inner side of the mounting bracket 2 is fixedly installed with a stepper motor 3. The output shaft of the stepper motor 3 penetrates to the outside of the mounting bracket 2 and is fixedly installed with a rotating disk 4. The top and bottom of one side of the rotating disk 4 are respectively movably installed with a first connecting rod 5 and a second connecting rod 6. The first flipping frame 7 is rotatably installed inside the frame 1, and the second flipping frame 8 adapted to the first flipping frame 7 is rotatably installed inside the frame 1. The ends of the first connecting rod 5 and the second connecting rod 6 far from the rotating disk 4 are respectively movably installed on the first flipping frame 7 and the second flipping frame 8.
[0027] The specific use process is as follows: first, the valve bag enters from one end of the frame 1 where the pressure roller 18 is installed, and it will first pass through the corresponding flat plate 13, and then enter the machine, and be transported forward on all the conveying rollers 11. During operation, the valve mouth belt passes through the frame 1 and also passes under the pressure roller 18. In this way, the pressure roller 18 can limit the valve bag to ensure that the material can smoothly enter the machine for processing, and the height of the sliding block 17 can also be flexibly adjusted according to the thickness of the conveyed material to meet the actual processing needs. Specifically, the user turns the adjusting screw 16. Because the sliding block 17 is threadedly connected to the adjusting screw 16, when the adjusting screw 16 is turned to work, the sliding block 17 will The movable chamber 15 moves up, and vice versa, the movable chamber 15 moves down. In this way, when the sliding block 17 moves and adjusts, the pressure roller 18 will also move and adjust accordingly. In this way, the distance between the pressure roller 18 and the conveying roller 11 will be adjusted to meet the conveying needs of materials of different thicknesses, providing convenience for the user's work. The cross bar is fixed on the inner side of the bracket 14, and the movable arm 19 and the torsion spring 20 are both installed on the cross bar. When working, the pressure roller 21 is tilted downward, because under the action of the torsion spring 20, the end of the movable arm 19 equipped with the pressure roller 21 is tilted downward, so that the valve bag passing through the frame 1 will be restricted by the pressure roller 21 and will not be lifted, thereby avoiding the valve bag from being blocked in the machine, ensuring the normal and smooth conveying of materials, and providing convenience for the user's work. Convenient, and under the action of the torsion spring 20, the pressure roller 21 can also make adaptive automatic adjustment according to the thickness of the material, so that the pressure roller 21 is always pressed on the material, and then under the recognition of the scanning device, the stepper motor 3 starts to work and drives the rotating disk 4 to rotate. It should be noted that the scanning device is a prior art, and the specific model and size are commonly used in daily life. It can meet the actual work needs. No more explanation is given in the text. Then, the rotation of the rotating disk 4 will simultaneously drive the connecting rod 1 5 and the connecting rod 2 6 to move, wherein the connecting rod 1 5 moves in the direction of the flip frame 1 7, and the connecting rod 2 6 moves in the direction away from the flip frame 1 7, so that the connecting rod 2 6 can drive the flip frame 2 8 to flip in the direction of the flip frame 1 7, and the flip frame 1 7 will turn to the flip frame 2 8 The valve bag is then turned over in the same direction, so that the valve bag brought up by the turning frame 2 8 will be caught by the turning frame 1 7, and then the turning frame 1 7 can complete the turning over of the valve bag when it is played back. In the initial state, the turning frame 2 8 is located on the inner side of the frame 1, and brings up the valve bag from the bottom. Similarly, the turning frame 1 7 is also located on the inner side of the frame 1 in the initial state, and works synchronously with the turning frame 2 8. Therefore, after the turning frame 1 7 returns to the inner side of the frame 1, the valve bag will fall back onto the conveying roller 11 for conveyance. At this time, the valve bag has been turned over, so the turning over of the valve bag can be completed, ensuring that the valve bag entering the next processing step meets the subsequent processing requirements, reducing manpower input, and improving the processing speed of the valve bag.Improve the processing efficiency of valve bags and provide convenience for users' work. Among them, the support rods 9 on the first turnover frame 7 and the second turnover frame 8 are used to lift the valve bag when turning it over, preventing the valve bag from falling off the first turnover frame 7 or the second turnover frame 8 and ensuring the normal progress of the turning-over work. The convex platform 10 is used to provide a fulcrum for the valve bag during the turning-over process, preventing the valve bag from moving randomly or slipping off the first turnover frame 7 and the second turnover frame 8 during the turning-over process, ensuring the normal progress of the turning-over work, and providing convenience for users' work. It should be noted that the rotation trajectory of the rotating disk 4 is in a reciprocating swinging state, and the range of this swinging angle is between zero and one hundred and seventy degrees. The actual swinging angle range can be automatically set by the user according to actual usage requirements. It should be noted that the valve bag is made of a composite of kraft paper and plastic film, with a relatively stiff texture that can maintain its original shape and will not collapse and fall during transportation, ensuring the normal transportation of the valve bag.
[0028] Therefore, a turnover structure is added to the conveying device, so that the valve bag directly meets the front and back requirements required by the next processing procedure during the process of being sent out from the previous work, to meet the processing requirements of the valve bag for the next procedure, reduce an artificial independent turnover procedure, simplify the processing steps of the valve bag, improve the processing efficiency of the valve bag, and provide convenience for users' use.
[0029] Both sides of the first turnover frame 7 and the second turnover frame 8 are fixedly connected with support rods 9, and convex platforms 10 are arranged at both ends of one side of the first turnover frame 7 and the second turnover frame 8.
[0030] Specifically, due to the settings of the support rod 9 and the convex platform 10, the support rod 9 is used to lift the valve bag when turning it over, preventing the valve bag from falling off the first turnover frame 7 or the second turnover frame 8 and ensuring the normal progress of the turning-over work. The convex platform 10 is used to provide a fulcrum for the valve bag during the turning-over process, preventing the valve bag from moving randomly or slipping off the first turnover frame 7 and the second turnover frame 8 during the turning-over process, ensuring the normal progress of the turning-over work, and providing convenience for users' work.
[0031] Equal-spacing distributed conveying rollers 11 are rotatably installed at both ends inside the frame 1, and guard plates 12 are fixedly installed on both sides of the top of the frame 1, and one end of the conveying roller 11 is rotatably installed on the guard plate 12.
[0032] Specifically, due to the settings of the conveying roller 11 and the guard plate 12, the guard plate 12 is used to play a role in blocking and protecting the work of the conveying roller 11, and at the same time also plays a role in supporting the work of the conveying roller 11. Since one end of the conveying roller 11 is movably installed on the guard plate 12, the stability of the conveying roller 11 during work is improved, providing convenience for users' work.
[0033] Both ends of the frame 1 are provided with flat plates 13, and the flat plates 13 are flush with the height of the guard plate 12.
[0034] Specifically, due to the setting of the flat plate 13, the flat plate 13 is used as a platform. During the process of feeding materials into the machine, a certain number of valve bags can be placed on the flat plate 13, reducing the frequency of handling materials, improving the efficiency of valve bag processing, and at the same time being able to play a guiding role in the feeding work of the valve bag, preventing the end of the valve bag from being accidentally inserted into the machine during feeding, providing convenience for the user's work.
[0035] One side of the top of the frame 1 is detachably installed with a bracket 14. The inner side of the bracket 14 is provided with a first pressing roller 18. The first pressing roller 18 is located above the conveying roller 11. Both sides of the bracket 14 are provided with sliding cavities 15. A sliding block 17 is slidably installed inside the sliding cavity 15. Both ends of the first pressing roller 18 are respectively rotatably installed on the two sliding blocks 17. Both sides of the top of the bracket 14 are penetrated with adjusting screws 16. The bottom end of the adjusting screw 16 penetrates into the sliding cavity 15 and is rotatably installed on the inner wall of the sliding cavity 15. The sliding block 17 is threadedly installed on the adjusting screw 16.
[0036] Specifically, due to the setting of the bracket 14, the sliding cavity 15, the adjusting screw 16, the sliding block 17 and the first pressing roller 18, during operation, the valve belt passes over the frame 1 and also passes under the first pressing roller 18. In this way, the first pressing roller 18 can play a role in limiting the valve bag, ensuring that the materials can smoothly enter the machine for processing. Moreover, the height of the sliding block 17 can be flexibly adjusted according to the thickness of the conveyed materials to meet the actual processing requirements. Specifically, the user rotates the adjusting screw 16. Since the sliding block 17 is threadedly connected to the adjusting screw 16, when the adjusting screw 16 is rotated, the sliding block 17 will move upward in the sliding cavity 15, and vice versa. In this way, when the sliding block 17 moves and adjusts, the first pressing roller 18 will also move and adjust accordingly. In this way, the distance between the first pressing roller 18 and the conveying roller 11 can be adjusted to meet the conveying requirements of different thicknesses of materials, providing convenience for the user's work.
[0037] A cross bar is fixedly installed on the inner side of the bracket 14. Both sides of the surface of the cross bar are movably installed with movable arms 19. One side of the movable arm 19 is rotatably installed with a second pressing roller 21. Both sides of the surface of the cross bar are sleeved with torsion springs 20. Both ends of the torsion spring 20 are respectively fixedly connected to the movable arm 19 and the cross bar.
[0038] Specifically, the cross bar, movable arm 19, torsion spring 20 and pressure roller 21 are arranged such that the cross bar is fixed on the inner side of the bracket 14, and the movable arm 19 and torsion spring 20 are both mounted on the cross bar. When working, pressure roller 21 is tilted downward, because under the action of torsion spring 20, one end of movable arm 19 on which pressure roller 21 is mounted is tilted downward, so that the valve bag passing through the frame 1 will be restricted by pressure roller 21 and will not tilt up, thus preventing the valve bag from being blocked in the machine, ensuring the normal and smooth transportation of materials, and providing convenience for users' work and use. Moreover, under the action of torsion spring 20, pressure roller 21 can also make adaptive automatic adjustments according to the thickness of the material, so that pressure roller 21 is always pressed tightly on the material.
[0039] It should be noted that the functions to be implemented by each hardware in the utility model are supported by a large number of mature technologies and belong to the existing technology.
