Description

Technical Field

[0002] A bulk bag (also called a flexible bulk bag, ton bag or ton bag) is a flexible container used to package bulk materials. It is usually made of synthetic fiber materials such as polypropylene (PP) or polyethylene (PE), and has sufficient strength and durability to withstand the weight of heavy objects and various stresses during transportation.

[0003] The existing Chinese patent with publication number CN220973514U discloses a cloth roll folding device for a ton bag container bag, but the patent and the traditional technology also have the following defects:

[0004] First, when the fabric is folded, different processes require different folding widths, and the folding groove width in the above patent cannot be adjusted. Therefore, after the folding process is changed, the original folding block needs to be disassembled and a suitable folding block needs to be reinstalled, which will reduce the folding efficiency of the fabric. In addition, in actual operation, multiple folding blocks with different widths need to be processed, which will increase the corresponding material finished product;

[0005] Secondly, in traditional technology, when the cloth is being cut, the transportation of the cloth will stop, and the ultrasonic pressure wheel that folds the cloth will stop rotating.

DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] refer to Figures 1 to 11 The illustrated container bag cutting and folding integrated device comprises a folding platform 1 and a cutting platform 2. The folding platform 1 is provided with a No. 1 driving roller 3 and a folding assembly. The No. 1 driving roller 3 is horizontal. The folding assembly comprises two groups of symmetrical ultrasonic pressing mechanisms. Each group of ultrasonic pressing mechanisms comprises an ultrasonic pressing wheel 4 and a limiting mechanism. The limiting mechanism comprises a U-shaped plate 5, a top plate 6 and an adjusting member. The U-shaped plate 5 is horizontally slidably arranged on the folding platform 1, and the opening of the U-shaped plate 5 faces the center of the folding platform 1. The top plate 6 is horizontally slidably arranged above the U-shaped plate 5. A downwardly bent strip hook portion 7 is formed on one end of the top plate 6 close to the opening of the U-shaped plate 5. A folding groove 8 (such as Fig. 9As shown in the figure, the adjusting member is arranged on the side of the U-shaped plate 5, and the adjusting member is used to adjust the width of the folding groove 8. A No. 2 driving roller 9 and a pressure plate 10 are provided on the cutting platform 2. The No. 2 driving roller 9 is parallel to the No. 1 driving roller 3. A floating roller shaft group is provided between the folding platform 1 and the cutting platform 2. The floating roller shaft group includes an active roller shaft 11, a driven roller shaft 12, a transmission mechanism and a driving member. The active roller shaft 11 and the driven roller shaft 12 are both parallel to the No. 1 driving roller 3. The driving member is used to drive the active roller shaft 11 to rise and fall. The transmission mechanism is used to drive the active roller shaft 11 and the driven roller shaft 12 to be connected, and the displacement direction of the driven roller shaft 12 is opposite to that of the active roller shaft 11.

[0034] The fabric for making the container bag is laid flat on the folding platform 1, and then the fabric is translated toward the first driving roller 3. During this process, the two sides of the fabric will pass through two sets of ultrasonic edge pressing mechanisms respectively. When the side of the fabric enters the folding groove 8, the side of the fabric will be bent through the inner cavity of the U-shaped plate 5, and finally Fig. 9 As shown in the figure, the side end of the cloth will collide with the strip hook 7, and the strip hook 7 is used to prevent the side end of the cloth from floating up and down. When the side of the cloth is located in the folding groove 8, the width of the folding groove 8 is the width of the folding side of the cloth. In actual operation, the width of the folding groove 8 is controlled by the adjusting member to adapt to different folding widths. When the side of the cloth is bent, the bent edge will pass through the ultrasonic pressing wheel 4. Under the action of ultrasonic waves, the ultrasonic pressing wheel 4 makes the surface of the bent edge Generate high-frequency vibration, so that the material softens and fuses, and then the upper and lower layers of the folding edge are closely connected. After the upper and lower layers of the folding edge are fixed, the cloth will pass through the No. 1 driving roller 3, and the No. 1 driving roller 3 is attached to the folding platform 1. The No. 1 driving roller 3 is used to drive the cloth to translate toward the cutting platform 2. When the cloth is initially folded, it needs to be translated by manually pushing the cloth. When the cloth is pressed under the No. 1 driving roller 3, the No. 1 driving roller 3 can realize the translation of the cloth;

[0035] The cloth that has left the folding platform 1 will first pass through the floating roller group and then fall onto the cutting platform 2. When the cloth passes through the floating roller group, the cloth first bypasses the active roller 11 upwards, and then bypasses the driven roller 12 downwards. After bypassing the driven roller 12, the cloth passes horizontally from under the No. 2 driving roller 9 and the pressing plate 10 in turn. In actual operation, a cutting machine is provided on the side of the pressing plate 10. Since the cutting machine is a prior art, it is not shown in the figure. The No. 2 driving roller 9 provided on the cutting platform 2 is used to cooperate with the No. 1 driving roller 3 to drive the cloth to move toward the cutting machine. When the cloth is being cut, the No. 2 driving roller 9 stops rotating, and the pressing plate 10 presses down to press the cloth tightly against the cutting platform 2. At the same time, the ultrasonic pressing mechanism continues to work. Since the No. 1 driving roller 3 continues to rotate, the cloth between the folding platform 1 and the cutting platform 2 will gradually increase and wrinkle. Therefore, a floating roller group is used to prevent the cloth from wrinkling. The specific working process of the floating roller group is as follows: the rotation speeds of the No. 1 driving roller 3 and the No. 2 driving roller 9 are kept consistent. After each round of cutting, the cloth between the folding platform 1 and the cutting platform 2 will gradually increase with the increase in the number of cutting times. At this time, the active roller 11 will rise in stages during the entire cutting process, and the corresponding driven roller 12 will fall in stages during the entire cutting process. In this way, the cloth between the cutting platform 2 and the folding platform 1 will gradually be tightened by the cooperation of the active roller 11 and the driven roller 12, and finally the cloth between the cutting platform 2 and the folding platform 1 will be prevented from gradually increasing and causing wrinkles. When all the cloth is cut, the active roller 11 begins to fall, and the driven roller 12 begins to rise until the active roller 11 and the driven roller 12 are level.

[0036] In order to show how the U-shaped plate 5 slides on the hemming platform 1, the following features are set:

[0037] Each set of limiting mechanisms also includes a fixing plate 13 (such as Figure 5 As shown in the figure, the fixing plate 13 is horizontally fixed on the folding platform 1, and a No. 1 slide bar 14 is formed on the side of the U-shaped plate 5 away from its opening. A plurality of No. 1 fixing pins 15 vertically upward are formed on the top of the fixing plate 13. A plurality of No. 1 slide grooves 16 corresponding to the No. 1 fixing pins 15 are formed on the No. 1 slide bar 14. The length direction of the No. 1 slide groove 16 is perpendicular to the transportation direction of the fabric. Each No. 1 fixing pin 15 passes through the corresponding No. 1 slide groove 16, and a No. 1 limiting nut 17 is screwed onto the upper end of each No. 1 fixing pin 15.

[0038] The U-shaped plate 5 is laterally translated on the fixed plate 13 through the No. 1 slide bar 14. When the U-shaped plate 5 is laterally translated, each No. 1 fixing pin 15 slides in the corresponding No. 1 slide groove 16. The No. 1 limit nut 17 screwed on the upper end of the No. 1 fixing pin 15 is used to prevent the No. 1 slide bar 14 from floating up and down, thereby ensuring that the U-shaped plate 5 can only be translated in a direction perpendicular to the cloth transportation.

[0039] In order to show how the top plate 6 slides over the U-shaped plate 5, the following features are provided:

[0040] A vertical plate 18 is formed on each fixed plate 13, and a frame plate 19 parallel to the fixed plate 13 is formed on the top of the vertical plate 18. The frame plate 19 is located directly above the No. 1 slide bar 14, and a No. 2 slide bar 20 is provided on the top of the frame plate 19. A number of vertical connecting strips 21 are provided between the No. 2 slide bar 20 and the top plate 6, and each connecting strip 21 is used to connect the No. 2 slide bar 20 and the top plate 6. A number of No. 2 fixing pins 22 pointing vertically upward are formed on the top of the frame plate 19, and a number of No. 2 slide grooves 23 corresponding to the No. 2 fixing pins 22 are opened on the No. 2 slide bar 20, and the No. 2 slide grooves 23 are parallel to the No. 1 slide groove 16, and each No. 2 fixing pin 22 passes through the corresponding No. 2 slide groove 23, and a No. 2 limiting nut 24 is screwed on the upper end of each No. 2 fixing pin 22.

[0041] The top plate 6 translates above the U-shaped plate 5 through the No. 2 slide bar 20. When the top plate 6 translates, each No. 2 fixing pin 22 slides in the corresponding No. 2 slide groove 23. The No. 2 limit nut 24 screwed on the upper end of the No. 2 fixing pin 22 is used to prevent the No. 2 slide bar 20 from floating downward, thereby ensuring that the translation direction of the top plate 6 is in a straight line with the translation direction of the U-shaped plate 5.

[0042] In order to show the specific structure of the adjustment part, the following features are set:

[0043] The adjusting member includes a handle 25, a rotating shaft 26, a worm wheel 27 and a worm 28. The rotating shaft 26 is horizontally rotatable on the vertical plate 18. The worm wheel 27 is coaxially fixed to the rotating shaft 26. The worm 28 rotates above the worm wheel 27, and the worm 28 is meshed with the worm wheel 27. A No. 1 protrusion 29 is formed on the top of the No. 1 slide bar 14. Both sides of the No. 1 protrusion 29 are formed with a horizontal No. 1 limit pin 30 (such as Figure 8 As shown in FIG. 1 ), a second protrusion 31 is formed at the bottom of the second slide bar 20, and a second horizontal stop pin 32 is formed on both sides of the second protrusion 31. The rotating handle 25 is vertically fixedly connected to one end of the rotating shaft 26 (combined with Figure 8 and Fig. 9 ), a No. 1 accommodating groove 33 and a No. 2 accommodating groove 34 are respectively provided at the upper and lower ends of the turning handle 25, the No. 1 protrusion 29 is located in the No. 2 accommodating groove 34, and the No. 2 protrusion 31 is located in the No. 1 accommodating groove 33, and two No. 1 strip grooves 35 are provided at the lower end of the turning handle 25, and each No. 1 limiting pin 30 passes through the corresponding No. 1 strip groove 35, and two No. 2 strip grooves 36 are provided at the upper end of the turning handle 25, and each No. 2 limiting pin 32 passes through the corresponding No. 2 strip groove 36.

[0044] When the worm 28 is rotated, the worm 28 drives the worm wheel 27 to rotate, so that the worm wheel 27 drives the rotating shaft 26 to rotate, and finally drives the rotating handle 25 to rotate through the rotating shaft 26. When the width of the folding groove 8 needs to be expanded, the rotating handle 25 rotates counterclockwise (such as Fig. 9 As shown in the figure, during this process, the upper end of the handle 25 will push the top plate 6 to move through the second protrusion 31, and the lower end of the handle 25 will push the U-shaped plate 5 to move through the first protrusion 29, and the displacement directions of the top plate 6 and the U-shaped plate 5 are opposite. When the width of the folding groove 8 needs to be reduced, the handle 25 can be driven to rotate clockwise by rotating the worm 28. The handle 25 will rotate only when the worm 28 rotates, and the handle 25 will not rotate by itself, thereby preventing the top plate 6 and the U-shaped plate 5 from displacing by themselves.

[0045] In order to show the specific installation method of the ultrasonic pressure wheel 4, the following features are set:

[0046] Two symmetrical mounting frames 37 are fixedly provided on each folding platform 1 , each ultrasonic pressing wheel 4 is rotatably connected to the corresponding mounting frame 37 , and each fixed plate 13 is provided with an arched elastic sheet 38 located directly below the ultrasonic pressing wheel 4 .

[0047] The bent edge of the cloth is pressed between the ultrasonic pressing wheel 4 and the arched elastic sheet 38. The ultrasonic pressing wheel 4 will vibrate at high frequency when rotating, so that the upper and lower layers of the bent edge of the cloth are tightly connected through the ultrasonic pressing wheel 4. The arched elastic sheet 38 is used to buffer the vibration of the ultrasonic pressing wheel 4.

[0048] In order to show the specific installation method of the active roller shaft 11 and the driven roller shaft 12, the following features are set:

[0049] Both ends of the active roller shaft 11 are provided with a vertical No. 1 support frame 39 (such as Fig.10 As shown in the figure, each No. 1 support frame 39 is provided with a No. 1 strip groove 40 and a No. 2 strip groove 41, both of which are vertical, a No. 1 slider 42 is slidably provided in the No. 1 strip groove 40, and a No. 2 slider 43 is slidably provided in the No. 2 strip groove 41, the two ends of the active roller shaft 11 are respectively connected to the two No. 1 sliders 42 for rotation, and the two ends of the driven roller shaft 12 are respectively connected to the two No. 2 sliders 43 for rotation.

[0050] The active roller 11 is lifted and lowered by two No. 1 sliders 42, and the driven roller 12 is lifted and lowered by two No. 2 sliders 43, and both the active roller 11 and the driven roller 12 can rotate, so that the active roller 11 and the driven roller 12 will not affect the normal transportation of the cloth.

[0051] In order to show the specific structure of the transmission mechanism, the following features are set:

[0052] The transmission mechanism includes two groups of traction parts which are symmetrically arranged on two No. 1 support frames 39, each group of traction parts includes a traction rope 44 and two transmission wheels 45, the two transmission wheels 45 rotate symmetrically on the top of the No. 1 support frame 39, the traction rope 44 is sleeved on the two transmission wheels 45, both ends of the traction rope 44 hang down, and the two ends of the traction rope 44 are respectively fixedly connected to the No. 1 slider 42 and the No. 2 slider 43, the driving part includes two symmetrical No. 1 hydraulic cylinders 46, each No. 1 hydraulic cylinder 46 is vertical, the two No. 1 hydraulic cylinders 46 are respectively fixedly arranged in two No. 1 strip through grooves 40, and the output end of each No. 1 hydraulic cylinder 46 is upwardly fixedly connected to the No. 1 slider 42.

[0053] Hydraulic cylinder No. 1 46 is used to drive slider No. 1 42 to move up and down. When slider No. 1 42 rises, slider No. 2 43 will drop due to its own weight. When slider No. 1 42 drops, slider No. 2 43 will rise through the transmission of traction rope 44. As a result, when active roller 11 rises, driven roller 12 will drop. Finally, the cloth between folding platform 1 and cutting platform 2 is tightened by the cooperation of active roller 11 and driven roller 12.

[0054] In order to show how the platen 10 is raised and lowered, the following features are provided:

The pressing plate 10 is horizontal, and the two ends of the pressing plate 10 are respectively fixedly connected to two No. 3 sliders 49, and a vertical No. 2 hydraulic cylinder 50 is fixedly provided in each No. 3 strip-shaped through groove 48, and the output end of the No. 2 hydraulic cylinder 50 is downwardly fixedly connected to the corresponding No. 3 slider 49.

[0056] The two No. 2 hydraulic cylinders 50 are started synchronously, and the two No. 3 slide blocks 49 are driven to rise and fall respectively through the two No. 2 hydraulic cylinders 50, and finally the pressure plate 10 is driven to rise and fall through the two No. 3 slide blocks 49. When the cloth is cut, the pressure plate 10 descends to press the cloth tightly on the cutting platform 2. When the cloth cutting is completed, the pressure plate 10 rises and the cloth continues to be transported forward.

[0057] Working principle:

[0058] The fabric for making the container bag is laid flat on the folding platform 1, and then the fabric is translated toward the first driving roller 3. During this process, the two sides of the fabric will pass through two sets of ultrasonic edge pressing mechanisms respectively. When the side of the fabric enters the folding groove 8, the side of the fabric will be bent through the inner cavity of the U-shaped plate 5, and finally Fig. 9As shown in the figure, the side end of the cloth will collide with the strip hook 7, and the strip hook 7 is used to prevent the side end of the cloth from floating up and down. When the side of the cloth is located in the folding groove 8, the width of the folding groove 8 is the width of the folding side of the cloth. In actual operation, the width of the folding groove 8 is controlled by the adjusting member to adapt to different folding widths. When the side of the cloth is bent, the bent edge will pass through the ultrasonic pressing wheel 4. Under the action of ultrasonic waves, the ultrasonic pressing wheel 4 makes the surface of the bent edge Generate high-frequency vibration, so that the material softens and fuses, and then the upper and lower layers of the folding edge are closely connected. After the upper and lower layers of the folding edge are fixed, the cloth will pass through the No. 1 driving roller 3, and the No. 1 driving roller 3 is attached to the folding platform 1. The No. 1 driving roller 3 is used to drive the cloth to translate toward the cutting platform 2. When the cloth is initially folded, it needs to be translated by manually pushing the cloth. When the cloth is pressed under the No. 1 driving roller 3, the No. 1 driving roller 3 can realize the translation of the cloth;

[0059] The cloth that has left the folding platform 1 will first pass through the floating roller group and then fall onto the cutting platform 2. When the cloth passes through the floating roller group, the cloth first bypasses the active roller 11 upwards, and then bypasses the driven roller 12 downwards. After bypassing the driven roller 12, the cloth passes horizontally from under the No. 2 driving roller 9 and the pressing plate 10 in turn. In actual operation, a cutting machine is provided on the side of the pressing plate 10. Since the cutting machine is a prior art, it is not shown in the figure. The No. 2 driving roller 9 provided on the cutting platform 2 is used to cooperate with the No. 1 driving roller 3 to drive the cloth to move toward the cutting machine. When the cloth is being cut, the No. 2 driving roller 9 stops rotating, and the pressing plate 10 presses down to press the cloth tightly against the cutting platform 2. At the same time, the ultrasonic pressing mechanism continues to work. Since the No. 1 driving roller 3 continues to rotate, the cloth between the folding platform 1 and the cutting platform 2 will gradually increase and wrinkle. Therefore, a floating roller group is used to prevent the cloth from wrinkling. The specific working process of the floating roller group is as follows: the rotation speeds of the No. 1 driving roller 3 and the No. 2 driving roller 9 are kept consistent. After each round of cutting, the cloth between the folding platform 1 and the cutting platform 2 will gradually increase with the increase in the number of cutting times. At this time, the active roller 11 will rise in stages during the entire cutting process, and the corresponding driven roller 12 will fall in stages during the entire cutting process. In this way, the cloth between the cutting platform 2 and the folding platform 1 will gradually be tightened by the cooperation of the active roller 11 and the driven roller 12, and finally the cloth between the cutting platform 2 and the folding platform 1 will be prevented from gradually increasing and causing wrinkles. When all the cloth is cut, the active roller 11 begins to fall, and the driven roller 12 begins to rise until the active roller 11 and the driven roller 12 are level.
