Description

Technical Field

[0001] This invention relates to the field of container bag production technology, specifically to a feeding device for container bag production. Background Technology

[0002] FIBCs, also known as bulk bags, space bags, or flexible container bags, are large packaging containers used for transporting bulk materials. Their core production process can be summarized as follows: using polypropylene or polyethylene resin as raw material, a series of processes such as drawing, weaving, coating, cutting, and sewing are carried out to finally manufacture a sturdy and durable flexible transport packaging bag.

[0003] The patent with publication number CN117841462B allows for the layering and storage of the base fabric material after cutting the FIBC (Flexible Intermediate Bulk Container) in a material box. This ensures that multiple sheets of base fabric do not stick together when used, effectively improving the work efficiency of operators during sewing. Furthermore, the layered storage eliminates the need for manual layering, and the layered storage also ensures the flatness of the base fabric material, facilitating sewing. The material box is reusable, effectively improving the production efficiency and quality of FIBC products.

[0004] The above technical solution stores the base fabric material of the cut FIBC in layers in the material box, ensuring that multiple sheets of base fabric material do not stick together when used, effectively improving the work efficiency of operators during sewing. However, when switching between FIBC raw material tubes of different widths, it is difficult to ensure that the center axis of the raw material tube is strictly aligned with the center line of the production line. Operators can only rely on experience and repeatedly tap and move the end of the raw material tube with a rubber hammer or pad for rough correction. This is not only time-consuming and laborious, but also has extremely low centering accuracy. It is very easy for the subsequent cutting dimensions to be out of tolerance due to positional deviation. At the same time, during the continuous rotation and unwinding of the raw material tube or its movement along the conveyor line, due to the lack of an effective lateral limit and dynamic correction device, the base fabric material will inevitably experience unidirectional or reciprocating deviation. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a feeding device for the production of bulk bags, which solves the problems mentioned in the background section.

[0011] The synchronous trimming mechanism includes a connecting rod mounted on the guide limiting cone, a telescopic rod mounted on the connecting rod, a trimming disc mounted on the telescopic rod, and a direction limiting frame mounted on the processing frame; The directional limiting frame is connected to the telescopic rod, and the surface of the processing frame is provided with a sliding groove. The sliding groove is connected to the telescopic rod, which realizes the synchronous cutting position according to the width of the raw material cylinder, and realizes the real-time matching between the cutting position and the width of the raw material. On the one hand, it saves the tedious operation of manually adjusting the cutting position, avoids the dimensional deviation caused by manual adjustment, and ensures that the raw material cutting edge is neat and uniform with regular edges.

[0012] The pressing and smoothing mechanism includes a turntable mounted on the conveying roller, a linkage rod mounted on the turntable, a pressure roller mounted on the processing frame, a pressing roller mounted on the processing frame, and a connecting plate mounted on the pressing roller.

The cleaning roller has bristles on its surface, and the arc-shaped telescopic scraper is arc-shaped.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, the sliding plate is attached to the surface of the raw material placement plate. The sliding plate moves downwards until it fixes and limits the raw material cylinder, thus restricting its movement and preventing displacement from the source. This limits the cylinder's position and prevents shaking or shifting during winding and feeding, ensuring the stability of the raw material conveying process. When the cylinder diameter is too large, the cylinder will press the overall limiting rod downwards until the guiding limiting cone remains in contact, achieving adaptive limiting for raw material cylinders of different diameters without requiring manual adjustment. The device can be adapted to raw material cylinders of different diameters, improving its versatility. At the same time, it fits the outer wall of the raw material cylinder throughout the process to achieve secondary operation limit, further enhancing the stability of the raw material cylinder and preventing misalignment of the raw material conveying due to cylinder shaking. Subsequently, the staff will wind the raw material cylinder, and the raw material will be tightened by the conveying roller. The tension adjustment roller will be adjusted by the elastic potential energy of the telescopic spring rod to avoid excessive looseness or tightness, which would affect the conveying of the raw material. This ensures that the raw material is always in a moderate and stable tension state, guaranteeing the continuity and stability of the raw material conveying.

[0017] 2. In this invention, the telescopic rod moves to move the cutting disc to the edge of the raw material for cutting. This achieves synchronous cutting position according to the width of the raw material cylinder, realizing real-time matching between the cutting position and the width of the raw material. On the one hand, it eliminates the tedious operation of manually adjusting the cutting position and avoids dimensional deviations caused by manual adjustment, ensuring that the raw material cutting edge is neat and uniform with regular edges. The pressing roller moves in conjunction with the pressure roller to press the conveyed raw material, preventing wrinkles on the surface of the raw material from affecting the subsequent processing effect. It effectively smooths out wrinkles and protrusions on the surface of the raw material caused by winding and conveying, and avoids dimensional deviations and processing defects in subsequent cutting and sewing processes caused by wrinkles.

[0018] 3. In this invention, the raw material is contacted and corrected by the edge limiting frame, and the raw material is limited by its own U-shape to avoid displacement or shaking of the raw material, which would affect the processing accuracy and effect. At the same time, it effectively suppresses lateral displacement, vertical shaking and deviation of the raw material during conveying, cutting and pressing. The arc-shaped telescopic scraper contacts and adheres to the surface of the raw material to scrape and clean it. At this time, the arc shape of the arc-shaped telescopic scraper achieves the cleaning of dust and impurities and the guiding linkage effect. At the same time, the arc design avoids scratching or damaging the surface of the raw material and ensures the integrity of the raw material. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-5 One embodiment of the present invention is as follows: A feeding device for producing FIBCs (Flexible Intermediate Bulk Containers) includes a processing frame 1, a raw material placement plate 2, and a conveying roller 21. The raw material placement plate 2 is mounted on the processing frame 1, and the conveying roller 21 is mounted on the processing frame 1. The feeding device for producing FIBCs further includes: Tension adjusting roller 22; An auxiliary feeding and conveying device for assisting feeding and conveying and improving stability during the process includes a tension adjustment mechanism installed on the processing frame 1, a raw material guiding mechanism installed on the raw material placement plate 2, and a raw material limiting mechanism installed on the raw material guiding mechanism. The tension adjustment mechanism is used to adjust the tension of the conveyed fabric. The raw material guiding mechanism is used to passively guide the raw material cylinder; The raw material limiting mechanism is used to fix and limit the raw material cylinder; The tension adjustment mechanism includes a tension adjustment roller 22 mounted on the processing frame 1, a collar 23 mounted on the tension adjustment roller 22, and a telescopic spring rod 24 mounted on the processing frame 1.

[0023] The raw material guiding mechanism includes a limiting rod 31 installed on the raw material placement plate 2, a guiding limiting cone 32 installed on the limiting rod 31, a fixed plate 33 installed on the limiting rod 31, a telescopic spring rod 34 installed on the fixed plate 33, and a spring rod 35 installed on the raw material placement plate 2.

[0024] The raw material limiting mechanism includes a force-bearing arc block 41 installed on the raw material placement plate 2, a spring rod 42 installed on the raw material placement plate 2, a sliding plate 43 installed on the spring rod 42, a limiting cover plate 44 installed on the sliding plate 43, and a tension spring 45 installed on the limiting cover plate 44.

[0025] The free end of the telescopic spring rod 24 is connected to the collar 23, the telescopic spring rod 34 is connected to the guide limiting cone 32, the spring rod 35 is connected to the limiting rod 31, the spring rod 42 is connected to the force-bearing arc block 41, the tension spring 45 is connected to the sliding plate 43, the surface of the guide limiting cone 32 is set as arc surface 1, which is used to assist the raw material cylinder in being squeezed and stressed, the surface of the raw material placement plate 2 is provided with a raw material placement groove, which is used to place and fix the raw material cylinder, the raw material placement groove is in contact with the surface of the limiting cover plate 44, the raw material placement groove and the limiting cover plate 44 are in contact to improve the fixing effect of the raw material cylinder, the surface of the force-bearing arc block 41 is set as arc surface 2, which is used to be in contact with the raw material cylinder, the surface of the raw material placement plate 2 is provided with a force groove, the force groove is used to apply force to the diameter of the raw material cylinder and adapt to it, the force groove is connected to the limiting rod 31.

[0026] In this embodiment, during operation: the worker places the raw material cylinder on the raw material placement plate 2. When the raw material cylinder moves downwards and contacts and presses against the limiting cover plate 44, it rotates adaptively, allowing the raw material cylinder to pass through. Subsequently, the limiting cover plate 44 resets under the action of the tension spring 45. Then, the raw material cylinder contacts and presses against the force-bearing arc block 41, moving downwards. At this time, the force-bearing arc block 41 moves downwards, driving the sliding plate 43 to move. Because the sliding plate 43 is in contact with the surface of the raw material placement plate 2, the sliding plate 43 moves downwards until it fixes and limits the raw material cylinder. This achieves the restriction of the raw material cylinder, avoiding the potential for displacement from the source, limiting the position of the raw material cylinder, and preventing shaking or swaying of the raw material cylinder during winding and feeding, ensuring the basic stability of the raw material conveying. At the same time, the raw material cylinder moves downwards and contacts and presses against the guide limiting cone 32. At this time, the guide limiting cone 32 moves away from the raw material cylinder under the pressure of the raw material cylinder. Subsequently, the raw material cylinder moves downwards and presses the guide limiting cone 32 to move to both sides. Until it no longer contacts the conical surface of the guide limiting cone 32, the telescopic spring rod 24 deforms and recovers, causing the guide limiting cone 32 to move closer to the raw material cylinder until it limits the operation of the raw material cylinder. At the same time, when the diameter of the raw material cylinder is too large, the raw material cylinder will squeeze the overall limiting rod 31 downward until the guide limiting cone 32 always remains in contact, realizing adaptive limiting for raw material cylinders of different diameters. It can adapt to raw material cylinders of different diameters without manual adjustment, improving the versatility of the device. At the same time, it adheres to the outer wall of the raw material cylinder throughout the process to achieve secondary operation limiting, further strengthening the stability of the raw material cylinder and avoiding misalignment of the raw material conveying due to cylinder shaking. Then, the staff will wind the raw material cylinder, and the raw material will be tightened by the conveying roller 21. The tension adjustment roller 22 will be adjusted by the elastic potential energy of the telescopic spring rod 24 to avoid excessive looseness or tightness, which would affect the conveying of the raw material. The raw material will always be in a moderate and stable tension state, ensuring the continuity and stability of the raw material conveying.

[0027] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the auxiliary feeding and conveying device further includes an adaptive processing device installed on the guide limiting cone 32. The adaptive processing device includes a synchronous trimming mechanism installed on the guide limiting cone 32 and a pressing and smoothing mechanism installed on the synchronous trimming mechanism. Among them, the adaptive processing device is used to process raw material cylinders of different widths; The synchronous trimming mechanism is used to trim the edges of raw material cylinders of different widths. The pressing and smoothing mechanism is used to press and smooth the raw materials.

[0028] The synchronous trimming mechanism includes a connecting rod 51 mounted on the guide limiting cone 32, a telescopic rod 52 mounted on the connecting rod 51, a trimming disc 53 mounted on the telescopic rod 52, and a direction limiting frame 54 mounted on the processing frame 1. The direction limiting frame 54 is connected to the telescopic rod 52, and the surface of the processing frame 1 is provided with a sliding groove. The sliding groove is used to facilitate the operation of the telescopic rod 52 and is connected to the telescopic rod 52.

[0029] The pressing and smoothing mechanism includes a turntable 61 mounted on the conveying roller 21, a linkage rod 62 mounted on the turntable 61, a pressure roller 63 mounted on the processing frame 1, a pressing roller 64 mounted on the processing frame 1, and a connecting plate 65 mounted on the pressing roller 64; The linkage rod 62 is connected to the pressing roller 64.

[0030] In this embodiment, during operation: when the guide limiting cone 32 moves away from the raw material cylinder under the contact and compression action of the raw material cylinder, the moving guide limiting cone 32 drives the connecting rod 51 to move. At this time, the movement of the connecting rod 51 drives the telescopic rod 52 to move, and the movement of the telescopic rod 52 drives the edge cutting disc 53 to move to the edge of the raw material for edge cutting. This achieves synchronous edge cutting position according to the width of the raw material cylinder, realizing real-time matching between the edge cutting position and the width of the raw material. On the one hand, it eliminates the tedious operation of manually adjusting the edge cutting position and avoids the problems caused by manual adjustment. To ensure uniform and neat edges of the raw material, the conveyor roller 21 rotates, driving the turntable 61 to rotate. The turntable 61 then rotates, driving the linkage rod 62 to rotate. This linkage rod 62 then drives the pressing roller 64 to move up and down repeatedly. The pressing roller 64, in conjunction with the pressure roller 63, presses the conveyed raw material, preventing wrinkles on the surface from affecting subsequent processing. This effectively smooths out wrinkles and protrusions on the surface of the raw material caused by winding and conveying, preventing wrinkles from causing dimensional deviations and processing defects in subsequent cutting and sewing processes.

[0031] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the auxiliary feeding and conveying device further includes a correction and cleaning device installed on the direction limiting frame 54, and the synchronous cleaning device includes a synchronous correction mechanism installed on the direction limiting frame 54 and a synchronous cleaning mechanism installed on the synchronous correction mechanism. Among them, the deviation correction and cleaning device is used to correct and clean the raw materials; The synchronous correction mechanism is used to perform synchronous correction based on the cutting edge components; The synchronous cleaning mechanism is used to perform synchronous cleaning of the cut-edge components.

[0032] The synchronous correction mechanism includes a sliding frame 71 mounted on the direction limiting frame 54, a fixed rod 72 mounted on the sliding frame 71, a telescopic spring rod 73 mounted on the sliding frame 71, and an edge limiting frame 74 mounted on the telescopic spring rod 73. Among them, the fixed rod 72 is connected to the telescopic rod 52, and the edge limiting frame 74 is rotatably connected to the telescopic spring rod 73.

[0033] The synchronous cleaning mechanism includes a cleaning roller 81 mounted on an edge limiting frame 74 and an arc-shaped telescopic scraper 82 mounted on an edge limiting frame 74; The cleaning roller 81 has bristles on its surface, which are used to clean the raw material by brushing. The arc-shaped telescopic scraper 82 is arc-shaped, which is to prevent damage to the raw material during operation and to guide the impurities that are removed during cleaning.

[0034] In this embodiment, when the cutting disc 53 moves under the action of the connecting rod 51 to adapt to the width of the raw material cylinder, the free end of the telescopic rod 52 moves, causing the fixed rod 72 to move. The fixed rod 72 moves, causing the sliding frame 71 to move. The sliding frame 71 moves, causing the telescopic spring rod 73 to move. At the same time, the telescopic spring rod 73 moves, causing the sliding frame 71 to move. Simultaneously, the edge limiting frame 74 contacts and corrects the material, and limits the material by its own U-shape, avoiding material displacement or shaking, which would affect the processing accuracy and effect. It also effectively suppresses lateral displacement, vertical shaking, and deviation of the material during conveying, cutting, and pressing. At the same time, the edge limiting frame 74 rotates in contact with the surface of the material. The rotation of the edge limiting frame 74 causes the brush bristles to rotate, performing a close-fitting cleaning of the material surface. At the same time, the arc-shaped telescopic scraper 82 contacts and adheres to the surface of the material to scrape and clean it. At this time, the arc shape of the arc-shaped telescopic scraper 82 achieves the cleaning of dust and impurities and the guiding linkage effect. At the same time, the arc design avoids scratching or damaging the surface of the material, ensuring the integrity of the material.
