Description

Technical Field

[0001] The present invention relates to the technical field of industrial woven bag production equipment, and in particular to an industrial woven bag cutting and sewing linkage device and a use method thereof. Background Art

[0002] In the modern industrial production system, industrial woven bags are widely used as a packaging material in many fields such as chemicals, building materials, and food. Their production efficiency and quality directly affect the development of related industries. The production process of industrial woven bags covers multiple links, among which cutting and sewing are two crucial processes. Their operating effects and synergy play a decisive role in the final quality and production efficiency of woven bags.

[0003] In the traditional industrial woven bag production mode, the cutting and sewing processes are usually completed by separate equipment. In the cutting process, a simple cutting machine is generally used. This type of cutting machine often relies on manual operation. Workers need to measure and mark the rolled woven bag raw materials according to the approximate size requirements before starting the cutting machine for cutting. This operation method is not only inefficient, but also due to the errors in manual measurement and operation, it is difficult to ensure the size accuracy of the woven bag after cutting, and large size deviations often occur. In actual production, the length deviation of the woven bag after cutting may reach ±5mm or even larger. This will bring great inconvenience to some application scenarios that have strict requirements on the size of woven bags, such as high-precision chemical product packaging, and may even cause product packaging to be unqualified, affecting the sales and use of the product;

[0004] In terms of the sewing process, when traditional sewing machines are sewing woven bags, the position of the woven bags on the sewing machine is prone to deviation due to the lack of effective positioning and fixing measures during the transfer of the woven bags from the cutting equipment to the sewing equipment. According to statistics, about 30% of the woven bags will have varying degrees of position deviation during the sewing process, which directly affects the quality of the sewing, for example, there will be problems such as uneven stitches and uneven stitch lengths. In severe cases, it may even lead to suture breakage and leaking, which greatly reduces the product qualification rate and increases production costs.

[0005] In addition, since the cutting and sewing equipment are independent of each other and there is no effective linkage mechanism between the two, the production process requires a lot of manual intervention. Workers not only need to move the woven bags to the sewing equipment after cutting, but also need to frequently adjust equipment parameters and conduct quality inspections in each process. Taking a medium-sized woven bag production plant as an example, to produce 10,000 woven bags a day, at least five workers are required to be responsible for the connection and operation of the cutting and sewing processes, which undoubtedly increases labor costs; moreover, the uncertainty and fatigue of manual operation will further affect production efficiency and the stability of product quality.

[0020] A method for using an industrial woven bag cutting and sewing linkage device, comprising:

[0021] Step 1: Unwinding link. When the entire industrial woven bag cutting and sewing linkage device is started, the unwinding link starts to operate first. The unwinding motor is powered on and starts to start. The drive head at the output end of the unwinding motor accurately cooperates with the drive slot at one end of the reel to form a tight connection structure. As the unwinding motor runs, the drive head drives the reel to start rotating. At this time, the rolled woven bag raw materials are slowly unwound. In order to adapt to raw material rolls of different widths, two threaded sections are specially set on the reel, and limit rings are installed on the threaded sections. The operator can flexibly adjust the position of the limit ring according to the actual width of the raw material roll. The socket on the limit ring plays a key role. The operator can insert the socket with the help of a tool to turn the limit ring more conveniently and labor-savingly, so that it can be accurately moved to the appropriate position, thereby effectively limiting the raw material roll to prevent it from shaking left and right during the unwinding process. In addition, when faced with rolled woven bags of different thicknesses, the height of the two adjustable reel support assemblies needs to be adjusted. The specific adjustment method is as follows: First, the operator inserts the positioning screw into the fixed hole corresponding to the required height to prepare for the subsequent adjustment operation. Next, the adjustable reel support assembly is rotated so that the support column is accurately located between the first clamping block and the fourth clamping block to form a stable clamping structure. Finally, the positioning nut is tightened to firmly position the adjustable reel support assembly at a suitable height. After completing the height adjustment, the rolled woven bag is steadily lifted to the coil placement mechanism by the crane. At this time, the bearing on the reel can be flexibly rotated on the bearing support seat to ensure that the reel can rotate smoothly. Subsequently, the unwinding motor is installed, and the drive head on the unwinding motor is accurately inserted into the drive slot, so that the unwinding link can operate normally and stably.

[0022] Step 2: In the feeding and straightening stage, the woven bag raw materials conveyed from the unwinding link enter the feeding and straightening stage. Each straightening motor starts at the same time to provide power for the rotation of the rotating roller. The limit plate installed on the rotating roller plays an important limiting role to prevent it from deviating left and right during the conveying process, ensuring that the raw materials can be stably conveyed along the predetermined track. The woven bag raw materials bypass each rotating roller and adjusting roller in turn. In this process, the adjusting component begins to play a key role, and the driving component on the adjusting component starts to operate, which drives the adjusting frame to swing up and down. The adjusting roller on the adjusting frame cooperates with the rotating roller. Through this coordinated action, the woven bag raw materials are carefully straightened. Under the joint action of the adjusting roller and the rotating roller, the wrinkles and bends in the raw materials are gradually eliminated, and finally the conveyed raw materials are ensured to be flat and straight. After such treatment, the raw materials are stably conveyed to the feeding mechanism to prepare for subsequent processes;

[0023] Step 3: Feeding process. After the feeding mechanism receives the woven bag raw materials that have been straightened, the feeding motor is turned on. The power output of the feeding motor causes the upper feeding roller and the lower feeding roller to start rotating synchronously. The upper and lower feeding rollers fit closely together to form a powerful clamping and conveying structure to further flatten the woven bag raw materials. At the same time, relying on the friction generated between the roller surface and the raw materials, the raw materials are continuously pulled toward the cutting mechanism. In the second half of the feeding box, there is an inclined surface. The positioning rod, the pressing sheet and the guide roller arranged on this inclined surface work together. The positioning rod provides accurate positioning for the raw materials. The pressing sheet gently presses the raw materials to prevent them from jumping or shifting during the conveying process. The guide roller guides the raw materials to move forward smoothly in the predetermined direction. Through their joint cooperation, the raw materials are secondary positioned and guided to ensure that the raw materials can be stably and accurately conveyed to the cutting mechanism.

[0024] Step 4: Cutting operation. When the raw materials of the woven bag are accurately conveyed to the cutting mechanism, the cutting operation begins. The material transfer motor starts and drives the material transfer shaft to rotate. The material transfer cylinder on the material transfer shaft rotates with the rotation of the material transfer shaft, and the single woven bag to be cut is conveyed to the direction of the receiving mechanism until the woven bag is accurately located on the receiving mechanism. Then, the cutting knife begins to work. The knife seat moves slowly downward under the drive of the displacement table. When the knife seat drops to a certain position, the pressure plate first contacts the woven bag. The pressure plate is like a stabilizer, pressing the woven bag tightly and pressing it down to prevent the woven bag from moving during the cutting process. To ensure the accuracy of cutting, the displacement table continues to move downward. At this time, the spring is squeezed, and the elastic deformation of the spring produces a stable and uniform pressure. This pressure is transmitted to the woven bag through the cutting knife to achieve the cutting of the woven bag. In the process of the cutting knife moving downward, the guide column plays a vital role. The guide column is like a precise track, guiding the cutting knife to move downward smoothly, ensuring the stability of the cutting process and the cutting quality, so that the edges of the cut woven bags are neat and the size is accurate.

[0025] Step 5: Material splicing and sewing process. Since the width of the splicing table is smaller than that of the cutting table, the cut woven bag part will naturally be located on the conveyor belt. After cutting is completed, the feeding motor starts to drive the central shaft to rotate. The second pressing wheel on the central shaft rotates with the rotation of the central shaft. When the second pressing wheel contacts the cut woven bag, it will gently press the woven bag, providing an initial power and stable contact state for the conveying of the woven bag. At the same time, the conveying motor of the sewing mechanism starts to drive the power shaft to rotate. The rotation of the power shaft drives the conveyor belt to start running, and the conveyor belt conveys the woven bag smoothly forward. During the conveying process of the woven bag, the first pressing wheel of the material guide assembly guides and positions the woven bag again. The first pressing wheel ensures that the woven bag is always in the conveying process. The correct position and direction are always maintained to ensure the stability of the position of the woven bag during the sewing process, which provides a good foundation for the subsequent sewing process. When the woven bag is transported to the hemming and leveling component, the folding plate and the limit plate begin to play a role. When the edge of the woven bag contacts the folding plate, the folding plate will cleverly fold the part that exceeds the folding plate. At this time, the folded part will enter the folding channel. In the folding process, the leveling wheel plays a key leveling role. The woven bag is leveled while folding, ensuring the flatness of the woven bag during the folding process. After folding and leveling, the woven bag continues to be transported to the sewing machine. When the woven bag reaches the sewing machine position, the sewing machine starts working to accurately sew the folded part, and finally completes the sewing of the woven bag.

[0026] Step 6: Unloading step. The woven bags after stitching continue to be transported forward with the conveyor belt. When most of the woven bags are no longer on the conveyor belt and begin to fall down, the receiving rack comes into play. At this time, the receiving rack is located between the woven bags and the conveyor platform, ready for the unloading of the woven bags.

[0027] The rotating motor starts and drives the receiving rack to rotate toward the transmission mechanism. During the rotation process, the receiving rack smoothly unloads the woven bags to the transmission mechanism below. The transmission mechanism transports the finished woven bags to the subsequent process for further processing, or transports them to the storage area for storage. The working process of the entire industrial woven bag cutting and sewing linkage device has completed a complete cycle.

[0028] The beneficial effects of the present invention are:

[0029] Efficient production: A fully automated process from unwinding to unloading is realized, and each mechanism works closely together without frequent manual intervention. Unwinding, feeding, cutting, sewing and other links are carried out simultaneously, greatly reducing production time. The cutting shears and sewing machines work quickly, increasing the output per unit time, and the efficiency is significantly improved compared with traditional production methods.

[0030] Quality assurance: The feeding and straightening mechanism ensures that the raw materials are flat and straight through rotating rollers, adjusting rollers and other components; the positioning and guiding structure of the feeding mechanism ensures the accurate position of the raw materials. When cutting, the guide column enables the cutting knife to move smoothly, and the cutting edges are neat and the size is accurate; before sewing, the guide and curling and leveling components are in place, allowing the sewing machine to sew accurately, improving product quality and appearance.

[0031] Strong versatility: The adjustable reel support assembly can adjust the height according to the different thicknesses of the rolled woven bags, and is easy to operate. The limit ring on the reel can flexibly adjust the position according to the width of the raw material roll, which enhances the adaptability of the equipment to raw materials of different specifications.

[0032] Stable operation: The device has a reasonable structure design, and each motor is easy to control, which makes it easy for operators to use and reduces the skill level requirements. During operation, springs, guide columns and other components ensure the stability of key operations, and the rotating rollers and feed rollers rotate stably, reducing failures, improving equipment reliability, and reducing maintenance costs and downtime.

[0033] Save labor: High automation reduces manual operations and labor costs. Workers do not need to perform high-intensity, repetitive labor, the working environment is improved, labor intensity is reduced, and work enthusiasm and satisfaction are improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0071] A method for using the industrial woven bag cutting and sewing linkage device as claimed in claim 9, comprising:

[0072] Step 1: Unwinding link. When the entire industrial woven bag cutting and sewing linkage device is started, the unwinding link starts to operate first. The unwinding motor 18 is powered on and starts to start. The driving head 19 at the output end of the unwinding motor 18 accurately cooperates with the driving groove 20 at one end of the reel 13 to form a tight connection structure. As the unwinding motor 18 runs, the driving head 19 drives the reel 13 to start rotating. At this time, the rolled woven bag raw material is slowly unwound. In order to adapt to raw material rolls of different widths, two threaded sections 15 are specially provided on the reel 13. A limit ring 16 is installed on the threaded section 15. The operator can flexibly adjust the position of the limit ring 16 according to the actual width of the raw material roll. The socket 17 on the limit ring 16 plays a key role. The operator can insert the socket 17 with the help of a tool to turn the limit ring 16 more conveniently and labor-savingly, so that it can be accurately moved to the appropriate position, thereby effectively limiting the raw material roll to prevent it from shaking left and right during the unwinding process. In addition, when facing rolled woven bags of different thicknesses, it is necessary to adjust the heights of the two adjustable reel support assemblies 12. The specific adjustment method is as follows: First, the operator inserts the positioning screw 39 into the fixing hole 52 corresponding to the required height to prepare for subsequent adjustment operations. Next, the adjustable reel support assembly 12 is rotated so that the support column 11 is accurately located between the first clamping block 35 and the fourth clamping block 38 to form a stable clamping structure. Finally, the positioning nut 50 is tightened to firmly position the adjustable reel support assembly 12 at a suitable height position. After completing the height adjustment, the rolled woven bag is stably lifted to the coil placement mechanism 1 by the crane. At this time, the bearing 30 on the reel 13 can be flexibly rotated on the bearing support seat 31 to ensure that the reel 13 can rotate smoothly. Subsequently, the unwinding motor 18 is installed, and the drive head 19 on the unwinding motor 18 is accurately inserted into the drive slot 20, so that the unwinding link can operate normally and stably.

[0073] Step 2: In the feeding and straightening stage, the woven bag raw materials conveyed from the unwinding link enter the feeding and straightening stage. Each straightening motor 60 is started at the same time to provide power for the rotation of the rotating roller 58. The limit plate 59 installed on the rotating roller 58 plays an important limiting role to prevent it from being deviated left and right during the conveying process, ensuring that the raw materials can be stably conveyed along the predetermined track. The woven bag raw materials bypass each rotating roller 58 and the adjusting roller 65 in turn. In this process, the adjusting component 62 begins to play a key role, and the driving component 66 on the adjusting component 62 starts to operate, which drives the adjusting frame 63 to swing up and down. The adjusting roller 65 on the adjusting frame 63 cooperates with the rotating roller 58. Through this coordinated action, the woven bag raw materials are carefully straightened. Under the joint action of the adjusting roller 65 and the rotating roller 58, the wrinkles and bends in the raw materials are gradually eliminated, and finally the conveyed raw materials are ensured to be flat and straight. After such treatment, the raw materials are stably conveyed to the feeding mechanism 3 to prepare for subsequent processes.

[0074] Step 3: Feeding process. After the feeding mechanism 3 receives the woven bag raw materials that have been straightened, the feeding motor 85 is turned on. The power output of the feeding motor 85 causes the upper feeding roller 81 and the lower feeding roller 82 to start rotating synchronously. The upper and lower feeding rollers fit closely together to form a powerful clamping and conveying structure to further flatten the woven bag raw materials. At the same time, relying on the friction generated between the roller surface and the raw materials, the raw materials are continuously pulled toward the cutting mechanism 5. In the rear half of the feeding box 79, there is an inclined surface 86. The positioning rod 87, the pressing sheet 88 and the guide roller 89 arranged on this inclined surface work together. The positioning rod 87 provides accurate positioning for the raw materials. The pressing sheet 88 gently presses the raw materials to prevent them from jumping or shifting during the conveying process. The guide roller 89 guides the raw materials to move forward smoothly in the predetermined direction. Through their joint cooperation, the raw materials are secondary positioned and guided to ensure that the raw materials can be stably and accurately conveyed to the cutting mechanism 5.

[0075] Step 4: Cutting operation. When the raw material of the woven bag is accurately conveyed to the cutting mechanism 5, the cutting operation begins. The material transfer motor starts to drive the material transfer shaft 95 to rotate. The material transfer cylinder 96 on the material transfer shaft 95 rotates with the rotation of the material transfer shaft 95, and the single woven bag to be cut is conveyed to the direction of the material receiving mechanism 6 until the woven bag is accurately located on the material receiving mechanism 6. Then, the cutting knife 97 begins to work, and the knife seat 98 moves slowly downward under the drive of the displacement table 99. When the knife seat 98 drops to a certain position, the pressing plate 102 first contacts the woven bag. The pressing plate 102 is like a stabilizer, pressing the woven bag tightly and performing The guide post 100 is used to press down and position the woven bag to prevent it from moving during the cutting process. This ensures the accuracy of cutting. The displacement table 99 continues to move downward. At this time, the spring 103 is squeezed. The elastic deformation of the spring 103 produces a stable and uniform pressure, which is transmitted to the woven bag through the cutting knife 97 to achieve the cutting of the woven bag. In the process of the cutting knife 97 moving downward, the guide post 100 plays a vital role. The guide post 100 is like a precise track, guiding the cutting knife 97 to move downward smoothly, ensuring the stability and cutting quality of the cutting process, so that the edges of the cut woven bag are neat and the size is accurate.

[0076] Step 5: Material joining and sewing process. Since the width of the material joining table 107 is smaller than that of the cutting table, the cut woven bag part will naturally be located on the conveyor belt 115. After the cutting is completed, the feeding motor 127 is started to drive the central shaft 126 to rotate. The second pressing wheel 129 on the central shaft 126 rotates with the rotation of the central shaft 126. When the second pressing wheel 129 contacts the cut woven bag, it will gently press the woven bag, providing an initial power and stable contact state for the transportation of the woven bag. At the same time, the conveying motor 116 of the sewing mechanism 7 is started to drive the power shaft 156 to rotate. The rotation of the power shaft 156 drives the conveyor belt 115 to start running, and the conveyor belt transports the woven bag forward smoothly. In the process of conveying the woven bag, the first pressing wheel 122 of the material guide assembly 117 guides and positions the woven bag again. The first pressing wheel 122 ensures that the woven bag is transported The correct position and direction are always maintained during the conveying process to ensure that the position of the woven bag is stable during the sewing process, which provides a good foundation for the subsequent sewing process. When the woven bag is conveyed to the curling and leveling component 130, the folding plate 133 and the limit plate 135 begin to play a role. When the edge of the woven bag contacts the folding plate 133, the folding plate 133 will cleverly fold the part that exceeds the folding plate 133. At this time, the folded part will enter the folding channel 136. During the folding process, the leveling wheel 137 plays a key leveling role. The woven bag is leveled while folding, ensuring the flatness of the woven bag during the folding process. After the folding and leveling treatment, the woven bag continues to be conveyed in the direction of the sewing machine 152. When the woven bag reaches the position of the sewing machine 152, the sewing machine 152 starts to work and accurately sews the folded part, and finally completes the sewing of the woven bag.

[0077] Step 6: Unloading step. The woven bags after stitching are continuously conveyed forward along with the conveyor belt 115. When most of the woven bags are no longer on the conveyor belt 115 and begin to fall downward, the receiving rack 158 comes into play. At this time, the receiving rack 158 is just located between the woven bags and the conveyor platform 113, ready for unloading the woven bags. The rotating motor 159 is started to drive the receiving rack 158 to rotate toward the transmission mechanism 9. During the rotation, the receiving rack 158 smoothly unloads the woven bags onto the transmission mechanism 9 below. The transmission mechanism 9 conveys the finished woven bags to the subsequent process for further processing, or conveys them to the storage area for storage. The working process of the entire industrial woven bag cutting and stitching linkage device has completed a complete cycle.

At this time, the bearing (30) on the reel (13) can be flexibly rotated on the bearing support seat (31) to ensure that the reel (13) can rotate smoothly. Subsequently, the unloading motor (18) is installed, and the drive head (19) on the unloading motor (18) is inserted into the drive slot (20); Step 2: During the feeding and straightening stage, each straightening motor (60) is started simultaneously, and the limit plate (59) installed on the rotating roller (58) prevents the woven bag raw material from being deviated to the left or right during the conveying process; the woven bag raw material passes around each rotating roller (58) and the adjusting roller (65) in turn, and the driving component (66) on the adjusting component (62) starts to operate, which drives the adjusting frame (63) to swing up and down. The adjusting roller (65) on the adjusting frame (63) cooperates with the rotating roller (58). Through this coordinated action, the woven bag raw material is carefully straightened. Under the joint action of the adjusting roller (65) and the rotating roller (58), the wrinkles and bends in the raw material are eliminated, ensuring that the conveyed raw material is flat and straight. After such treatment, the raw material is stably conveyed to the feeding mechanism (3) to prepare for the subsequent process; Step 3: Feeding process, the feeding motor (85) is turned on, and the power output of the feeding motor (85) causes the upper feeding roller (81) and the lower feeding roller (82) to start rotating synchronously, forming a powerful clamping and conveying structure, further flattening the woven bag raw material, and at the same time, relying on the friction generated between the roller surface and the raw material, continuously pulling the raw material toward the cutting mechanism (5); the positioning rod (87) provides accurate positioning for the raw material, the pressing sheet (88) gently presses the raw material to prevent it from jumping or shifting during the conveying process, and the guide roller (89) guides the raw material to move forward smoothly in the predetermined direction. Through their joint cooperation, the raw material is secondary positioned and guided to ensure that the raw material can be stably and accurately conveyed to the cutting mechanism (5); Step 4: Cutting operation. When the raw material of the woven bag is accurately conveyed to the cutting mechanism (5), the cutting operation begins. The material transfer motor starts to drive the material transfer shaft (95) to rotate. The material transfer cylinder (96) on the material transfer shaft (95) rotates along with the rotation of the material transfer shaft (95) to transfer the single woven bag to be cut to the direction of the material receiving mechanism (6) until the woven bag is accurately located on the material receiving mechanism (6). Subsequently, the knife seat (98) is driven by the displacement table (99) to slowly move downward. When the knife seat (98) drops to a certain position, the pressure plate (102) first contacts the woven bag and presses it downward to prevent the woven bag from moving during the cutting process. To ensure the accuracy of cutting, the displacement table (99) continues to move downward. At this time, the spring (103) is squeezed. The elastic deformation of the spring (103) generates a stable and uniform pressure. This pressure is transmitted to the woven bag through the cutting knife (97) to achieve cutting of the woven bag. Step 5: Material joining and sewing process. Since the width of the material joining table (107) is smaller than the width of the cutting table, the cut woven bag part will naturally be located on the conveyor belt (115). After the cutting is completed, the feeding motor (127) is started to drive the central shaft (126) to rotate. The second pressing wheel (129) on the central shaft (126) rotates with the rotation of the central shaft (126); at the same time, the conveying motor (116) of the sewing mechanism (7) is started to drive the power shaft (156) to rotate. The rotation of the power shaft (156) drives the conveyor belt (115) to start running. The conveyor belt transports the woven bag forward smoothly. During the conveying process of the woven bag, the first pressing wheel (122) of the material guide assembly (117) guides and positions the woven bag again. The first pressing wheel (122) ensures that the woven bag always maintains the correct position during the conveying process. The position and direction of the woven bag are ensured to be stable in the position during the sewing process, which provides a good foundation for the subsequent sewing process. When the woven bag is conveyed to the curling and leveling component (130), when the edge of the woven bag contacts the folding plate (133), the folding plate (133) will fold the part exceeding the folding plate (133). At this time, the folded part will enter the folding channel (136). During the folding process, the leveling wheel (137) plays a key leveling role. The woven bag is leveled while folding, which ensures the levelness of the woven bag during the folding process. After the folding and leveling process, the woven bag continues to be conveyed to the sewing machine (152). When the woven bag reaches the position of the sewing machine (152), the sewing machine (152) starts to work and accurately sews the folded part, thus completing the sewing of the woven bag. Step 6: Unloading step. The woven bag after stitching is continuously conveyed forward along the conveyor belt (115). When most of the woven bag is no longer on the conveyor belt (115) and begins to fall downward, the receiving rack (158) comes into play. At this time, the receiving rack (158) is located exactly between the woven bag and the conveyor platform (113), ready for unloading of the woven bag. The rotating motor (159) is started to drive the receiving rack (158) to rotate toward the transmission mechanism (9). During the rotation process, the receiving rack (158) smoothly unloads the woven bag to the transmission mechanism (9) below. The transmission mechanism (9) conveys the finished woven bag to the subsequent process for further processing.
