[0001] This utility model belongs to the field of bag opening machine technology, and specifically discloses a rotating folding module for a bag opening machine. Background Technology

[0002] The folding module of a bag opening machine is a core functional component of automated bag opening equipment, specifically designed for precise folding of bag edges. It employs a high-precision rotary mechanism and servo drive system, along with an adjustable folding guide plate, to adapt to bag types of different materials and sizes. Its compact structure, easy assembly and disassembly, and wear-resistant durability make it widely used in automated packaging bag processing scenarios in the food, daily chemical, and pharmaceutical industries.

[0003] In existing bag-opening machines, the folding module mainly uses a folding blade and a fixed plate to press one side of the fabric towards the fixed plate, thereby bending the fabric. However, when sewing, the fixed plate retracts away from the folding blade. At this time, the fabric, lacking the pressure of the fixed plate, becomes loose, resulting in unstable sewing, poor sewing effect, and reduced finished product quality. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a rotating folding module for a bag opening machine, so as to solve the problem that the existing bag opening machine folding module mainly uses a folding knife and a fixed plate to squeeze one side of the fabric towards the fixed plate, which causes the fabric to bend, resulting in loose fabric, poor sewing effect, and reduced finished product quality.

[0005] To achieve the above objectives, this utility model provides a rotating folding module for a bag opening machine, including a mounting plate. A slide rail is fixedly connected to one side wall of the mounting plate, providing an installation position. Two sliding plates are slidably connected to the outside of the slide rail, allowing the sliding plates to slide outside the slide rail. A mounting frame is fixedly connected to one side wall of the sliding plate, providing an installation position. A flipping mechanism is provided on the outside of the mounting frame, and a folding knife mechanism is provided at the bottom of the mounting plate. The flipping mechanism is used to drive the folding knife mechanism to flip and fold the material.

[0006] In the above technical solution, preferably, the flipping mechanism includes a sliding sleeve, one side wall of which is fixedly connected to the outer wall of the mounting frame, a sliding rail is slidably connected inside the sliding sleeve, a fixing plate is fixedly connected to the top of the outer side of the sliding rail, a hydraulic cylinder is fixedly connected to one side wall of the fixing plate, the output end of the hydraulic cylinder is fixedly connected to the top of the mounting frame, a push plate is fixedly connected to the bottom of the sliding rail, and a flipping groove is formed on one side wall of the push plate.

[0007] In the above technical solution, preferably, the folding knife mechanism includes a mounting clamp, the top of which is fixedly connected to the bottom of the mounting plate, a mounting tube is fixedly connected inside the mounting clamp, a plurality of folding knives are rotatably connected to the outside of the mounting tube, a stop block is fixedly connected to the top of one side wall of the folding knife, a square block is fixedly connected to the top of the folding knife, an air inlet is provided inside the square block, an air outlet is provided inside the folding knife, and the air inlet and the air outlet are connected.

[0008] In the above technical solution, preferably, one side wall of the fixing plate is slidably connected to the outside of the mounting frame, and multiple mounting holes are opened inside the top of the mounting frame.

[0009] In the above technical solution, preferably, the top of the abutment block contacts the bottom of the push plate, and the top of the block contacts the inner wall of the folding groove.

[0010] In the above technical solution, preferably, the outer side of the mounting bracket is slidably connected to the top of the mounting plate, and one side wall of the sliding plate is slidably connected to the outside of the mounting plate.

[0011] In the above technical solution, preferably, the material inside the fixing plate is steel plate, and the material inside the push plate is aluminum alloy.

[0012] In the above technical solution, preferably, the inner wall of the sliding sleeve is provided with a wear-resistant coating, and the oil inlet and outlet of the hydraulic cylinder are both fixedly connected with flow control valves.

[0014] In the above technical solution, preferably, a wear-resistant lining plate is provided on one side wall of the sliding plate near the interior of the mounting plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention, through the cooperation of a folding mechanism and a folding knife mechanism, enables the rotational folding of the fabric.

[0018] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figures 1-8 The illustrated bag opening machine rotary folding module includes a mounting plate 1. A slide rail 2 is fixedly connected to one side wall of the mounting plate 1, providing an installation position. Two sliding plates 3 are slidably connected to the outside of the slide rail 2, allowing the sliding plates 3 to slide outside the slide rail 2. A mounting frame 4 is fixedly connected to one side wall of the sliding plate 3, providing an installation position. A flipping mechanism 5 is provided on the outside of the mounting frame 4. A folding knife mechanism 6 is provided at the bottom of the mounting plate 1. The flipping mechanism 5 is used to drive the folding knife mechanism 6 to flip the folded material. The outside of the mounting frame 4 is slidably connected to the top of the mounting plate 1, and one side wall of the sliding plate 3 is slidably connected to the outside of the mounting plate 1. Mounting plate 1 is made of high-strength aluminum alloy through a one-piece molding process, with a thickness of 15-20mm. The overall dimensions are designed to be 800-1000mm in length and 200-250mm in width. Its surface is anodized, which not only effectively improves wear resistance and corrosion resistance, but also reduces the adhesion of dust and debris generated during the fabric processing, ensuring the long-term stable operation of the module. As the basic load-bearing component of the entire rotating folding module, mounting plate 1 provides a precise installation benchmark and a stable support platform for each functional component. One side wall (preferably the vertical side wall) is fixedly connected to the slide rail 2 with M8-M10 hexagon socket head cap bolts. The bolt spacing is uniformly set at 100-150mm, and flat washers and spring washers are added at the bolt connection to further enhance the connection's firmness and prevent the slide rail 2 from loosening due to vibration during high-speed folding operations. The slide rail 2 adopts a high-precision linear slide rail, model HSR20-30 series, and its length is adapted to the length of the mounting plate 1, which is 800-1000mm. The guide rail groove of the slide rail 2 is equipped with a ball retainer. The balls are made of GCr15 bearing steel and have been quenched to achieve a hardness of HRC60-62, ensuring smoothness and wear resistance during sliding. At the same time, dustproof end caps are installed at both ends of the slide rail 2, which can effectively prevent dust, fabric fibers and other impurities from entering the guide rail groove and extend the service life of the slide rail 2.

[0021] The external sliding connection of the slide rail 2 consists of two sliding plates 3. The sliding plates 3 are made of Q235 steel plates, stamped and reinforced by welding, with a thickness of 10-12mm. Each sliding plate 3 has an integrally formed slider at its top and bottom that matches the slide rail 2. Precision raceways matching the ball bearings of the slide rail 2 are embedded inside the sliders. The sliders and sliding plates 3 are fixedly connected by bolts with a bolt spacing of 80-100mm, secured with anti-loosening nuts. One side wall of the sliding plate 3 (the side wall near the mounting bracket 4) has a welding bevel, and it is fixedly connected to the mounting bracket 4 by CO2 gas shielded welding. The weld height is 6-8mm. After welding, the weld is inspected to ensure there are no welding defects such as porosity or cracks, guaranteeing the connection strength. The other side wall of the sliding plate 3 (the side wall in contact with the mounting plate 1) is covered with a wear-resistant PTFE liner. The liner is 3-5mm thick and coated with high-temperature grease. This reduces the frictional resistance between the sliding plate 3 and the mounting plate 1 and prevents abnormal noise during sliding. The two sliding plates 3 are symmetrically arranged outside the slide rail 2. The spacing between them can be flexibly adjusted according to the folding width requirements of different specifications of fabric. The adjustment range is 200-500mm. The adjustment can be achieved by manual knob or electric drive mechanism, which greatly improves the versatility of the module.

[0022] A mounting frame 4 is fixedly connected to one side wall of the sliding plate 3. The mounting frame 4 is welded from rectangular steel pipe profiles. The main frame is a rectangular structure with a length of 300-400mm, a width of 150-200mm, and a height of 200-250mm. After welding, it undergoes stress relief treatment to ensure structural stability and prevent deformation during long-term use. As an intermediate load-bearing component connecting the sliding plate 3 and the flipping mechanism 5, the mounting frame 4 not only provides a stable mounting base for the flipping mechanism 5 but also slides synchronously with the sliding plate 3 along the slide rail 2, allowing for flexible adjustment of the folding position. The top of the mounting frame 4 is equipped with a sliding seat that is adapted to slide on the top of the mounting plate 1. The sliding seat is made of cast iron and its surface is precision ground, with a flatness error controlled within 0.02mm / m. The clearance between the sliding seat and the sliding guide rail on the top of the mounting plate 1 is 0.01-0.03mm to ensure the straightness accuracy of the mounting frame 4 during sliding. The outer wall of the mounting bracket 4 (corresponding to the installation position of the flipping mechanism 5) is milled to form a flat installation surface with a flatness error controlled within 0.03mm / m, providing a precise installation reference for the sliding sleeve 501 of the flipping mechanism 5 and ensuring the verticality of the flipping mechanism 5. The top of the mounting bracket 4 has 4-6 mounting holes with a diameter of 12-14mm, evenly spaced at 80-100mm. These mounting holes are not only used to accommodate the hydraulic cylinder 504 of the flipping mechanism 5, but also serve as expansion interfaces for other auxiliary functional components, enhancing the module's functional expandability. The mounting frame 4 is externally slidably connected to the top of the mounting plate 1. Through the cooperation of the top sliding seat and the sliding guide rail of the mounting plate 1, the mounting frame 4 slides synchronously with the sliding plate 3 along the slide rail 2, ensuring the relative position stability of the flipping mechanism 5 and the folding knife mechanism 6. One side wall of the sliding plate 3 is slidably connected to the outside of the mounting plate 1. Through wear-resistant lining, it contacts the side wall of the mounting plate 1, reducing sliding friction and providing guidance for the sliding of the sliding plate 3. This ensures the trajectory accuracy when the sliding plate 3 drives the mounting frame 4 and the flipping mechanism 5, thereby guaranteeing the accuracy and consistency of the folding action and meeting the high-precision folding processing requirements of the bag opening machine for fabrics of different specifications.

[0023] The flipping mechanism 5 includes a sliding sleeve 501, which provides an installation position. One side wall of the sliding sleeve 501 is fixedly connected to the outer wall of the mounting frame 4. A sliding rail 502 is slidably connected inside the sliding sleeve 501, allowing it to slide within the sleeve. A fixing plate 503 is fixedly connected to the top of the sliding rail 502, providing the installation position. A hydraulic cylinder 504 is fixedly connected to one side wall of the fixing plate 503, providing power for the push plate 505 to move up and down. The output end of the hydraulic cylinder 504 is fixedly connected to the top of the mounting frame 4. A push plate 505 is fixedly connected to the bottom of the sliding rail 502. A folding groove 506 is provided on one side wall of the push plate 505. One side wall of the fixing plate 503 is slidably connected to the outside of the mounting frame 4. The top of the mounting frame 4 is internally... Multiple mounting holes are provided. When the hydraulic cylinder 504 is activated, the output end of the hydraulic cylinder 504 retracts, thereby driving the fixed plate 503 to move downward. The fixed plate 503 drives the sliding rail 502 to move downward, thereby driving the push plate 505 to move downward. When the hydraulic cylinder 504 is activated again, the output end of the hydraulic cylinder 504 extends, thereby driving the fixed plate 503, the sliding rail 502 and the push plate 505 to move upward. The fixed plate 503 is made of steel plate, the push plate 505 is made of aluminum alloy, the inner wall of the sliding sleeve 501 is provided with a wear-resistant coating, the oil inlet and outlet of the hydraulic cylinder 504 are fixedly connected with flow control valves, the folding groove 506 is polished, the mounting plate 1 is made of high-strength aluminum alloy, and the side wall of the sliding plate 3 near the mounting plate 1 is provided with a wear-resistant liner. The sliding sleeve 501 is internally connected to a sliding rail 502, which is made of 40Cr alloy structural steel and heat-treated to achieve a hardness of HRC28-32, ensuring sufficient strength and toughness while also possessing good wear resistance. The outer diameter of the sliding rail 502 precisely matches the inner diameter of the sliding sleeve 501, with the tolerance controlled within the range of H7 / f6, ensuring that the sliding rail 502 can slide smoothly inside the sliding sleeve 501 without jamming or wobbling. The length of the sliding rail 502 is 250-300mm, and both ends are machined with a chamfered structure with a chamfer angle of 30-45°, facilitating the insertion of the sliding rail 502 into the sliding sleeve 501 while preventing sharp edges from scratching the inner wall of the sliding sleeve 501. The outer top of the sliding rail 502 is fixedly connected to the fixed plate 503 by welding. The weld adopts a V-shaped bevel design. After welding, non-destructive testing is carried out to ensure that the weld is free of defects such as pores and cracks, and the connection strength is not lower than the strength of the sliding rail 502 body. A fixing plate 503 is fixedly connected to the top of the sliding rail 502. The fixing plate 503 is made of Q235B steel plate, machined by CNC milling, with a thickness of 12-15mm and overall dimensions of 150-200mm in length and 80-100mm in width. Its surface flatness error is controlled within 0.02mm / m, providing a precise installation reference for the hydraulic cylinder 504. As an intermediate component connecting the sliding rail 502 and the hydraulic cylinder 504, the fixing plate 503 not only transmits the driving force of the hydraulic cylinder 504, but also ensures that the sliding rail 502 is evenly stressed through its own structure, preventing skewing during vertical movement. One side wall of the fixing plate 503 is slidably connected to the outside of the mounting bracket 4 via a slider. The slider is made of high-strength engineering plastic material with embedded balls, and cooperates with the pre-set guide groove on the mounting bracket 4. The straightness error of the guide groove is ≤0.01mm / m, ensuring the trajectory accuracy of the fixing plate 503 during vertical movement. The other side wall of the fixing plate 503 is fixedly connected to the cylinder body of the hydraulic cylinder 504 by bolts. The bolts are M12-M14, there are 4 bolts, they are arranged in a rectangle and the spacing is 60-80mm. Flat washers and spring washers are added at the bolt connection to further enhance the connection stability.

[0024] The folding blade mechanism 6 includes a mounting plate 601, which provides an installation position. The top of the mounting plate 601 is fixedly connected to the bottom of the mounting plate 1. An installation tube 602 is fixedly connected inside the mounting plate 601, providing the installation position. Multiple folding blades 603 are rotatably connected to the outside of the mounting tube 602. After rotating, the folding blades 603 can bend the fabric. A stop block 604 is fixedly connected to the top of one side wall of each folding blade 603. A block 605 is fixedly connected to a stop block 604. The block 605 and the stop block 604 can contact the bottom of the push plate 505 and the inner wall of the folding groove 506, thereby enabling the folding knife 603 to rotate and bend the fabric. An air inlet 606 is opened inside the block 605, and an air outlet 607 is opened inside the folding knife 603. The air inlet 606 and the air outlet 607 are connected. The top of the stop block 604 contacts the bottom of the push plate 505, and the top of the block 605 contacts the inner wall of the folding groove 506. At this point, when the bottom of the push plate 505 contacts the top of the abutment block 604, it can drive the abutment block 604 to rotate around the mounting tube 602, thereby driving the folding blade 603 to rotate. When the bottom of the push plate 505 leaves the top of the abutment block 604, the inner top of the folding groove 506 on the push plate 505 contacts the top of the block 605, thereby continuing to drive the folding blade 603 to rotate. When the block 605 is horizontally positioned, one side wall of the push plate 505 can abut against the top of the block 605, and through the rotation of the folding blade 603... It can bend the fabric, and can be inflated from the air inlet 606 and sprayed out from the air outlet 607. The sprayed gas can first blow and bend the fabric, and when the push plate 505 moves upward, it can drive the block 605 to rotate in the opposite direction, thereby driving the folding knife 603 to rotate in the opposite direction. When the folding knife 603 slowly rotates and resets, the air can still keep the fabric in a bent state, preventing the fabric from spreading or the bend from being extended, thus avoiding uneven sewing lines. The mounting frame 4 is externally equipped with a flipping mechanism 5. As the core power actuator of the entire module, the flipping mechanism 5 is fixedly connected to the mounting frame 4 for follow-up motion. Simultaneously, its reciprocating motion provides the power for the folding blade mechanism 6 to flip and bend the material, ensuring that the folding blade 603 can accurately complete the fabric bending action. The sliding sleeve 501 of the flipping mechanism 5 is bolted to the outer wall mounting plane of the mounting frame 4. The inner wall of the sliding sleeve 501 is coated with a wear-resistant coating with a thickness of 0.05-0.1mm, using titanium nitride coating technology. This effectively reduces the coefficient of friction between the sliding rail 502 and the sliding sleeve 501, improving sliding smoothness and component lifespan. The sliding rail 502 is slidably connected internally to the sliding sleeve 501. The length of the sliding rail 502 is 200-250mm, and the clearance between the sliding rail 502 and the sliding sleeve 501 is 0.02-0.04mm, ensuring that the sliding rail 502 slides smoothly within the sliding sleeve 501 without jamming. A fixing plate 503 is fixedly connected to the top of the sliding rail 502. The fixing plate 503 is made of steel plate with a thickness of 8-10mm and is fixed to the sliding rail 502 by bolts with a bolt spacing of 60-80mm. One side wall of the fixing plate 503 is slidably connected to the outside of the mounting bracket 4. The sliding contact surface is also equipped with a wear-resistant liner to ensure the stability of the fixing plate 503 when moving up and down. A hydraulic cylinder 504 is fixedly connected to one side wall of the fixing plate 503. The hydraulic cylinder 504 is a double-acting single-piston rod hydraulic cylinder with a rated working pressure of 1.5-2.5MPa and a stroke of 100-150mm. Its output end is fixedly connected to the top of the mounting bracket 4 through a flange. The oil inlet and outlet of the hydraulic cylinder 504 are respectively connected to flow control valves, which can realize precise adjustment of the up and down movement speed of the push plate 505. The adjustment range is 50-100mm / s to adapt to the folding requirements of fabrics of different thicknesses and materials. The output end of the hydraulic cylinder 504 is fixedly connected to the top of the mounting bracket 4. The bottom of the sliding rail 502 is fixedly connected to the push plate 505. The push plate 505 is made of aluminum alloy. The bottom and the inner wall of the folding groove 506 are precision polished with a surface roughness Ra≤0.8μm. This reduces friction loss between the push plate 604 and the square block 605 of the folding knife mechanism 6, and ensures the contact fit and the effectiveness of power transmission. The bottom of the mounting plate 1 is equipped with a folding blade mechanism 6. This mechanism, acting as a functional component directly performing the fabric bending action, works in conjunction with the flipping mechanism 5 to achieve precise and stable fabric bending. Simultaneously, an air-jet auxiliary function ensures the quality of the folding. The mounting clamp 601 of the folding blade mechanism 6 is made of welded steel plate with a thickness of 12-15mm. Its top is fixedly connected to the bottom of the mounting plate 1 using M10-M12 bolts with a bolt spacing of 120-150mm. The bolt connections are secured with double nuts to prevent loosening due to vibration. An installation tube 602 is internally fixed to the mounting clamp 601. The installation tube 602 is made of seamless steel pipe with an outer diameter of 20-25mm and a wall thickness of 3-4mm. The installation tube 602 is connected to the mounting clamp 601 using an interference fit with a tolerance of H7 / r6, ensuring the reliable fixation of the installation tube 602 and preventing radial movement of the folding blade 603 during rotation. The mounting tube 602 is externally rotatably connected to 2-4 folding blades 603. The folding blades 603 are evenly distributed on the mounting tube 602 according to the folding width. The folding blades 603 are made of 304 stainless steel with a thickness of 2-3mm. The blade part is sharpened and the hardness reaches HRC55-58, which can easily bend the fabric and avoid scratching the fabric surface. A stop block 604 is fixedly connected to the top of one side wall of the folding blade 603. The top of the stop block 604 is designed with an arc-shaped structure with a radius of 10-15mm to facilitate the transmission of force when the push plate 505 contacts it. A square block 605 is fixedly connected to the top of the folding blade 603. The top of the square block 605 is a flat plane that precisely fits the top of the inner side of the folding groove 506 on the push plate 505. Through the step-by-step contact between the stop block 604 and the square block 605 and the push plate 505, the folding blade 603 can rotate continuously with a rotation angle range of 0-90° to meet the angle requirements for fabric bending. The cube 605 has an air inlet 606 inside, and the folding blade 603 has an air outlet 607 inside. The air inlet 606 and the air outlet 607 are connected. The air inlet 606 is connected to an external air supply system through an air pipe. The air supply pressure is 0.3-0.5MPa. The diameter of the air outlet 607 is 0.8-1.2mm, and there are 4-6 outlets, which are evenly distributed near the blade of the folding blade 603. The gas sprayed out can pre-blow the fabric to assist in bending. At the same time, when the folding blade 603 is reset, the gas spray continues to maintain the bending state of the fabric, prevent the fabric from spreading or the bending point from being extended, and avoid uneven sewing thread in the subsequent sewing process.

[0025] Working principle: When hydraulic cylinder 504 is activated, its output end retracts, causing the fixed plate 503 to move downwards. The fixed plate 503 then moves the sliding rail 502 downwards, which in turn moves the push plate 505 downwards. When the bottom of the push plate 505 contacts the top of the abutment block 604, the abutment block 604 rotates around the mounting tube 602, causing the folding blade 603 to rotate. When the bottom of the push plate 505 leaves the top of the abutment block 604, the inner top of the folding groove 506 on the push plate 505 contacts the top of the block 605, continuing to rotate the folding blade 603. After the block 605 is set horizontally, one side wall of the push plate 505 can abut against the top of the block 605. The fabric can be bent by the rotation of the folding knife 603. At the same time, air can be injected from the air inlet 606 and sprayed out from the air outlet 607. The sprayed air can first blow and bend the fabric. When the push plate 505 moves upward, it can drive the block 605 to rotate in the opposite direction, which can drive the folding knife 603 to rotate in the opposite direction. When the folding knife 603 slowly rotates and resets, the air can still keep the fabric in a bent state, preventing the fabric from spreading or the bend from being extended. Therefore, it can avoid the phenomenon of uneven sewing thread.
