Description

Technical Field

[0001] This utility model relates to the field of garment processing technology, specifically to a fully automatic bag opening and folding mechanism. Background Technology

[0002] In the garment manufacturing industry, pocket opening machines, as key auxiliary equipment, are of great significance in improving production efficiency and product quality. The pocket opening process involves multiple steps, including cutting the pocket opening, folding the pocket, shaping the pocket lip, and sewing. Among these, the folding process involves folding the cut pocket opening inward to form a folded edge. The quality and efficiency of this process directly affect the final appearance of the pocket and the overall production progress.

[0003] Traditional folding methods rely heavily on manual operation, requiring workers to use experience and skill to fold the edges of the material. This method is not only labor-intensive and time-consuming, resulting in extremely low production efficiency, but also makes it difficult to guarantee consistency in manual operation. Different workers, or even the same worker at different times, can lead to variations in folding results, thus affecting product quality stability. At the same time, the continuous rise in labor costs places a heavy economic burden on enterprises, significantly limiting their ability to expand production scale and enhance market competitiveness.

[0004] To address the drawbacks of manual folding, automated folding devices have emerged in the industry. Some of these devices use multiple cylinders to drive push plates to achieve folding. Existing technology application number 202320338236.0 discloses an automatic bag-folding device for opening fabric bags, including a worktable and a slotted structure on the worktable. It further includes: a pressing and expanding component positioned above the worktable, comprising a pressing and expanding mold that fits into the slotted structure and a pressing drive component for raising and lowering the mold; and a folding edge component positioned below the worktable, comprising a lifting base and push plates mounted on the base, each push plate equipped with a push drive component for horizontal movement.

[0005] The automatic bag folding device described above folds the edges from below the slot by moving a push plate (folding blade). However, the push plate is a one-piece push plate, and the total length of the push plate (folding blade) cannot be adjusted. This limits its use when folding small bags, requiring the replacement of the entire set of folding blades. It cannot fold small bags with the smallest folding blade width, making it inflexible in use. Utility Model Content

[0006] The purpose of this utility model is to provide a fully automatic bag opening and folding mechanism to solve the problems mentioned in the background art, such as the inability to adjust the total length of the existing push plate, the limitations in handling small bag folding, the need to replace the entire set of folding blades, the inability to fold small bags with the minimum folding blade width, and the lack of flexibility in use.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An automatic bag opening and folding mechanism includes a fabric bag opening machine for processing fabric. A bag opening mechanism is located on the top of one side of the fabric bag opening machine, and a bag opening and folding mechanism is located on the top of the fabric bag opening machine on the same side as the bag opening mechanism. The bag opening and folding mechanism includes a folding component and a driving component. The folding component includes a folding knife fixing block arranged symmetrically and several small folding knives. Each small folding knife has an L-shaped structure on one side, with a through hole on its base. Each small folding knife has an integrally formed folding top plate on its top side near the inner wall. Each folding top plate has a ceramic plate on its top, and each ceramic plate has a protective chamfer structure near its four corners to prevent damage to the fabric.

[0009] Preferably, the folding knife fixing block is arranged in a straight line, and each folding knife fixing block is evenly provided with a mounting groove that matches the small folding knife base. Each mounting groove is provided with a mounting through hole that matches the fixing through hole.

[0010] Preferably, the driving component includes a connecting plate installed at the bottom of each of the folding knife fixing blocks, and a sliding guide rail connected to the bottom of each connecting plate. The sliding guide rail is perpendicular to the folding knife fixing block, and a support plate is connected to the bottom of the two sliding guide rails. The bottom of the support plate is connected to the driving cylinder inside the fabric bag opening machine.

[0011] Preferably, the small folding blades on the top of the two folding blade fixing blocks are evenly distributed in a staggered manner.

[0012] Preferably, the small folding knife can be detached to meet different pocket size requirements.

[0013] Preferably, the width of the ceramic plate at the top of each of the small folding knives is 6 mm.

[0014] This utility model has the following beneficial effects:

[0015] 1. The folding mechanism of this application adopts a detachable small folding knife. By disassembling and increasing or decreasing the number of small folding knives, the total length of the folding parts can be flexibly adjusted to accurately adapt to the folding needs of large and small pockets. In particular, it can achieve folding of 6mm wide pocket fabric with the smallest folding knife width, which makes up for the limitations of the existing integrated push plate folding knife in the processing of small pockets and greatly improves the equipment's processing capability for diverse garment pockets.

[0016] 2. The top of the small folding knife folding plate is equipped with a ceramic plate. The high hardness and smooth surface of ceramic reduce wear when rubbing against the fabric, reducing the risk of scratches and snagging. The protective chamfered structure at the top corners of the ceramic plate further avoids damage to the fabric from sharp edges during the folding process, ensuring that all kinds of fabrics maintain good texture and appearance after processing. It is suitable for processing high-end fine fabrics.

[0017] 3. The folding knife fixing block is equipped with a mounting groove and mounting through hole that match the base of the small folding knife. With the fixing through hole, the small folding knife can be quickly installed and removed without complicated tools or professional skills, which shortens the equipment downtime caused by changing the folding knife, improves production continuity and efficiency, and reduces the labor intensity of workers.

[0018] 4. The small folding blades at the top of the two folding blade fixing blocks are evenly distributed in a staggered manner. While ensuring the folding function, the structural layout is optimized, component interference is avoided, and the overall structural stability is improved. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see the appendix Figure 1-5 As shown, a fully automatic bag opening and folding mechanism includes a fabric bag opening machine 1 for processing fabric. A bag opening mechanism 11 and a bag opening and folding mechanism 12 are sequentially arranged on one side of the fabric bag opening machine 1. The bag opening and folding mechanism 12 includes a folding component and a driving component. The folding component includes a folding knife fixing block 121 arranged symmetrically and several small folding knives 122. Each small folding knife 122 has an L-shaped structure. A fixing through hole 126 is provided on the base of each small folding knife 122. A folding top plate 123 is integrally provided on the top of each small folding knife 122 near the inner wall. A ceramic plate 124 is provided on the top of each folding top plate 123. The ceramic material has high hardness and a smooth surface, greatly reducing friction loss with the fabric during the folding process. Each ceramic plate 124 has corner protectors near its four corners to prevent damage to the fabric. The damaged protective chamfer structure 125 effectively prevents scratches and snags, and is especially suitable for high-end fine fabrics such as silk and chiffon. The folding knife fixing block 121 is set in a straight line structure. Each folding knife fixing block 121 has a mounting groove 127 that matches the base of the small folding knife 122. Each mounting groove 127 has a mounting through hole 128 that matches the fixing through hole 126. It is easy to install and disassemble with bolts. The small folding knives 122 on the top of the two folding knife fixing blocks 121 are evenly distributed in a staggered manner. The staggered and even distribution of the small folding knives 122 on the top of the two folding knife fixing blocks 121 optimizes the structural layout, reduces the risk of component interference, and ensures smooth and stable folding action. The small folding knife 122 can be disassembled according to different pocket size requirements. The ceramic plate 124 on the top of a single small folding knife 122 is 6 mm wide.

[0027] The folding component includes symmetrically arranged folding knife fixing blocks 121 and several L-shaped small folding knives 122. The fixing through holes 126 of the small folding knife base cooperate with the mounting grooves 127 and mounting through holes 128 on the folding knife fixing blocks 121, allowing for quick assembly and disassembly of the small folding knives. The total length of the folding component can be flexibly adjusted according to the pocket size. During operation, after the fabric is cut by the opening mechanism 11, the drive cylinder drives the support plate 32, which in turn drives the sliding guide rail 31 and the folding knife fixing blocks 121 to move through the connecting plate 3. This causes the cross-arranged small folding knives to pass through the center of the fabric cut and then separate to both sides, folding the fabric under the fixed blade. Subsequently, the fabric is pressed tightly by the serrated pressure plate.

[0028] By disassembling and increasing the number of folding blades 122, the total length of the folding parts can be flexibly adjusted to precisely adapt to the folding needs of large and small pockets. In particular, the minimum folding blade width enables the folding of 6mm wide pocket fabric, which makes up for the limitations of the existing integrated push plate folding blade in the processing of small pockets and greatly improves the equipment's processing capabilities for diverse garment pockets.

[0029] Furthermore, the small folding blades 12 at the top of the two folding blade fixing blocks 121 are staggered and evenly distributed, avoiding interference between parts during folding and ensuring stable operation of the mechanism; the detachable feature allows the folding mechanism to quickly adapt to different pocket sizes, improving production flexibility. The detachable design makes it easy to adjust the total length of the folding blades to meet different pocket size requirements. The 6mm wide ceramic plate ensures minimum folding precision, which is more advantageous when used for fine fabrics, reducing waste and improving quality.

[0030] Please see the appendix Figure 1 , 2 As shown in Figure 5, the driving component includes a connecting plate 3 installed at the bottom of each folding knife fixing block 121. Each connecting plate 3 has a sliding guide rail 31 connected to its bottom. The sliding guide rail 31 is perpendicular to the folding knife fixing block 121. The perpendicular setting of the sliding guide rail 31 and the folding knife fixing block 121 provides stable and precise guidance for the movement of the folding component. During the folding process, it can effectively reduce the shaking and offset of the folding component during the movement, ensure the accuracy of the folding action, and enable the fabric to be accurately folded to the predetermined position, thereby improving the quality and consistency of the folding and reducing the defect rate. The bottom of the two sliding guide rails 31 is connected to a support plate 32. The bottom of the support plate 32 is connected to the drive cylinder inside the fabric bag opening machine 1. The drive cylinder serves as a power source and transmits power stably to the folding knife fixing block 121 through the support plate 32, the sliding guide rail 31, and the connecting plate 3. Compared with other transmission methods, this structure has low power loss, can quickly respond to control commands, realize the rapid movement and positioning of the folding component, thereby improving the folding efficiency and accelerating the production rhythm of the entire bag opening process.

[0031] After the fabric is cut by the opening mechanism 11, the control system of the fabric opening machine 1 sends a signal to instruct the drive cylinder to start working. After the drive cylinder starts, it generates thrust to push the support plate 32 to move. Since the bottom of the two sliding guide rails 31 is connected to the support plate 32, the movement of the support plate 32 drives the sliding guide rails 31 to move along their guide direction. The movement of the sliding guide rails 31 is transmitted to the folding knife fixing block 121 through the connecting plate 3. Since the connecting plate 3 is installed at the bottom of the folding knife fixing block 121, the folding knife fixing block 121 moves synchronously with the sliding guide rail 31, thereby driving the small folding knife 122 installed on the folding knife fixing block 121 to move to the fabric cutting position. When the small folding knife 122 reaches the center position of the fabric cutting, the drive cylinder continues to operate, causing the two folding knife fixing blocks 121 on the sliding guide rail 31 to drive the small folding knife 122 to separate to both sides, realizing the action of folding the fabric under the fixed blade, completing the folding process. Subsequently, the drive cylinder can control the folding component to reset according to the instruction, waiting for the next folding task.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
