[0001] The present application relates to the field of handbag processing, in particular to a handbag production line. BACKGROUND

[0002] A handbag is a simple bag, usually with two handles, hand-carrying, and made of various materials, including paper, PVC laser film, non-woven industrial paperboard, canvas, cotton, leather, synthetic leather, silk, etc. Handbags not only have practicality, but are often used as fashion accessories and are used with clothing. In addition, handbags are divided into various types according to their purpose and material, such as advertising handbags, gift handbags, decorative handbags, informative handbags, and commemorative handbags.

[0003] In the production process of handbags, it usually includes base material cutting, handle fixing, base material sewing, handbag packaging and other steps. With the continuous development of technology, the importance of handbags in people's lives not only lies in their practicality and convenience, but also involves environmental protection, brand promotion, fashion personality, and cultural dissemination. They have become an indispensable part of people's daily lives and have evolved and developed with the development of society and the changing needs of people. Therefore, the demand for handbags in society is also increasing, and how to improve the production efficiency of handbags has become a technical problem that technicians need to solve at this stage.

[0004] In the prior art, in order to improve the production efficiency of handbags, various handbag production lines have been designed, such as handle fixing devices, base material cutting devices, sewing devices, and packaging devices. In different production processes of handbags, corresponding processing machines are provided to replace manual production, which can realize uninterrupted production throughout the day, thereby improving production efficiency and reducing labor intensity. However, during the production process of handbags, when one process is completed and the next process is started, manual assistance is still required, or a transfer machine is set up for transfer. This method still has low production efficiency and cannot meet the production demand in a short period of time and in large quantities.

[0005] Therefore, the handbag production line in the prior art has the problem of low production efficiency when producing handbags. SUMMARY

[0006] To solve the above problems, the present application provides a handbag production line, comprising a rack, a base material processing device, a handle fixing device, a base material cutting device, a sewing device and a packaging device arranged on the rack.

[0007] The base material processing device is used to fold the edges of the base material and intermittently glue the edges of at least one side of the base material at a first predetermined interval along the length direction of the base material;

[0008] a handle fixing device, which fixes a handle at the folded edges of both sides of the base material at a second preset interval along the length direction of the base material;

[0009] a cutting device, which cuts the base material with the fixed handle to form a plurality of sheet units along the width direction of the base material;

[0010] a forming device, which performs sealing treatment on each of the sheet units to form the tote bag;

[0011] a packing device, which packs the tote bags in a preset number as a group;

[0012] a conveying device, which extends along the production line direction and sequentially passes through the base material processing device, the handle fixing device, the cutting device, the forming device, and the packing device, and the conveying device comprises a first speed matching unit arranged between the base material processing device and the handle fixing device, a second speed matching unit arranged between the handle fixing device and the cutting device, and a third speed matching unit arranged between the cutting device and the forming device;

[0013] a control unit, which is electrically connected with the first speed matching unit, the second speed matching unit, and the third speed matching unit, respectively; wherein,

[0014] the control unit controls the first speed matching unit to input the base material at a first speed, and to convey the base material to the handle fixing device at every first time threshold, and the first time threshold is determined according to the fixing frequency of the handle;

[0015] the control unit controls the second speed matching unit to input the base material at every first time threshold, and to convey the base material to the cutting device at every second time threshold, and the second time threshold is determined according to the cutting frequency of the cutting device;

[0016] the control unit controls the third speed matching unit to input the base material at every second time threshold, and to convey the sheet unit to the forming device at every third time threshold, and the third time threshold is determined according to the sealing frequency of the forming device.

[0017] The production line of the handbag can realize the production of the handbag by using the base material processing device to fold the edges of the base material and paste glue, using the handle fixing device to fix the handle on the two side edges of the base material, using the cutting device to cut the base material with the handle into a plurality of piece units, and using the forming device to form each piece unit into a handbag.

[0018] In actual production of the handbag, for some urgent large batch orders, not only the stability of the production line needs to be ensured, but also the production efficiency needs to be ensured. The production line of the handbag can ensure the transmission speed and time of the base material between different devices to be accurately adjusted by using the first, second and third speed matching units, so that the production line can be smoothly and efficiently operated, the base material is prevented from being torn or accumulated due to the speed difference, the stability of the entire production line can be ensured, and the production efficiency of the production line can be improved.

[0019] In addition, the production line of the handbag can accurately control the feeding speed of each process step (such as edge folding, glue pasting, handle fixing, cutting and sealing), and seamlessly connects between steps, reduces quality problems caused by improper operation or time delay. For example, the fixing position of the handle and the cutting accuracy can be ensured, and the appearance and functionality of the finally generated handbag are more consistent and reliable.

[0020] In addition, the automatic speed matching and time control reduces human errors and interventions, reduces the rate of defective products, thereby saving production costs, and the packing device packs the handbags in a preset number, which is convenient for subsequent inventory management and logistics transportation.

[0021] In use, the speed matching unit and the time threshold can be adjusted by the control unit, the production line can be quickly adjusted according to the requirements of different specifications and types of handbags, the production line can adapt to diversified production demands, and the utilization rate and applicability of the production line are improved.

[0022] Further, the production line of the handbag reduces the direct contact between workers and dangerous machines, ensures the safe operation of the production process, and reduces the risk of injury.

[0023] In summary, the handbag production line provided by the application can match the feeding speed of the base material between different processes on the basis of ensuring the stability and safety of the production line, improve the continuity of the production line during work, and make the production line run smoothly and efficiently, thereby improving the production efficiency of the handbag production line.

[0024] According to the handbag production line provided by the application, the first speed matching unit comprises a first input assembly arranged on the rack on the upstream side and a first output assembly arranged on the rack on the downstream side, the first input assembly is electrically connected with the control unit, and a first buffer assembly is further arranged between the first input assembly and the first output assembly.

[0025] The second speed matching unit comprises a second input assembly arranged on the rack on the upstream side and a second output assembly arranged on the rack on the downstream side, the second input assembly is electrically connected with the control unit, and a second buffer assembly is further arranged between the second input assembly and the second output assembly, and the third speed matching unit comprises a conveying assembly.

[0026] The control unit controls the first input assembly to pull the base material from the base material storage position to the first buffer assembly through the base material processing device at the first speed, and the base material extends to the first output assembly through the first buffer assembly.

[0027] The control unit controls the second input assembly to pull the base material from the first output assembly to the second buffer assembly through the handle fixing device at every first time threshold, and the base material extends to the second output assembly through the second buffer assembly, the second output assembly feeds the base material to the base material inlet of the conveying assembly at the second time threshold, and the sheet material unit through the base material outlet of the conveying assembly is respectively conveyed to the forming device at every third time threshold.

[0028] The technical scheme is adopted, the first input component pulls the base material from the base material storage position at a constant speed (first speed), and the base material is processed through the base material processing device. Then, the base material enters the first buffer component, which serves as a temporary storage area and can smoothly adjust the flow speed of the base material, reducing production interruptions caused by sudden speed changes or equipment failures. When the first output component needs it, the base material is stably output from the buffer component, ensuring the smooth progress of the subsequent process. The second input component pulls the base material from the first output component at every first time threshold (matching the fixed frequency of the handle) according to the instructions of the control unit, and after processing through the handle fixing device, it enters the second buffer component. This design allows the base material to maintain stable flow during handle fixing, while reducing waiting time and improving production efficiency. The second output component then delivers the base material to the conveying component according to the cutting frequency (second time threshold) to prepare for the next process. Through this scheme, even for flexible handle bag base material, it can ensure that it is in a tension state under different conveying speeds, thereby ensuring the stability of the production line during production.

[0029] In addition, the setting of the buffer component allows the production line to flexibly respond to speed differences and production rhythm changes between different process steps. When a certain process step (such as handle fixing) requires a longer time, the buffer component can store excess base material to avoid waiting for upstream equipment to stop; when the downstream equipment (such as the cutting device) is ready, the buffer component can quickly release the base material to ensure continuous operation of the production line. This design effectively reduces production interruptions and material waste caused by speed mismatches.

[0030] In addition, by precisely controlling the output time threshold (first time threshold, second time threshold) of each speed matching unit, each process step can be ensured to be carried out under optimal conditions. For example, the handle fixing device has enough time to firmly fix the handle on the base material, and the cutting device can cut at the correct position. This helps to improve the quality and consistency of the final product and reduce the rate of defective products.

[0031] Further, the entire speed matching and conveying process can be automatically controlled by the control unit, reducing the need for manual intervention. This not only reduces labor intensity, but also improves the automation level and stability of the production line. The automatic control system can also make corresponding adjustments according to the production state to ensure smooth operation of the production line.

[0032] According to the production line of the handle bag provided by the application, the first input component includes a first traction conveying roller group and a first driving part, the first driving part is electrically connected with the control unit, the first buffer component includes a plurality of first buffer rollers spaced in the height direction and rotationally connected to the rack, and the first output component includes a damping roller group; wherein,

[0033] The first driving component is fixedly connected to the rack, and an output shaft of the first driving component is in transmission connection with a driving roller in the first traction conveying roller set, and is arranged between the driving roller and a driven roller in the first traction conveying roller set via the base material clamping device of the base material processing device. The control unit controls the first driving component to drive the driving roller to rotate and interact with the driven roller to pull the base material at the first speed. The base material is pulled by the first traction conveying roller set via the base material processing device to the first buffer assembly and then passes between two rollers of the damping roller set after being arranged around a plurality of the first buffer rollers. The two rollers of the damping roller set have a damping force for the movement of the base material in the production line direction.

[0034] With the above technical solution, the first driving component is electrically connected to the control unit and can receive instructions from the control unit to accurately control the rotational speed of the driving roller in the first traction conveying roller set, thereby pulling the base material at the first speed. The driving roller interacts with the driven roller to ensure that the base material is stable and does not slip during transmission by clamping the base material, thereby reducing production interruptions and quality problems caused by base material deviation or falling. The plurality of first buffer rollers arranged at intervals in the height direction provide a temporary storage and buffer area for the base material. When the first traction conveying roller set pulls the base material at a constant speed, the base material can be arranged around a plurality of buffer rollers in sequence, which helps to smooth the transmission speed of the base material and reduces the impact on subsequent process steps caused by sudden changes in speed.

[0035] Further, the design of the buffer roller enables the production line to flexibly respond to speed differences between different process steps. When a certain process step requires a longer processing time (such as the base material processing device), the buffer roller can store excess base material to avoid waiting for upstream equipment to stop; when the downstream equipment (such as the first output assembly) is ready, the buffer roller can release the base material to ensure continuous operation of the production line.

[0036] Still further, the two rollers of the damping roller set generate a damping force for the movement of the base material in the production line direction. The damping effect helps to further stabilize the transmission speed of the base material and reduce production problems caused by excessive speed or slow speed. At the same time, the damping roller can also absorb vibrations and shocks during base material transmission to protect the production line equipment.

[0037] The damping roller set is connected to the first buffer assembly, and by adjusting the size of the damping force, the speed and time interval of the base material output from the first buffer assembly to the next process step (such as the handle fixing device) can be accurately controlled. This helps to maintain the stability and synchronization of the production line and improves production efficiency.

[0038] Therefore, the production line of the handbag provided by the present application can accurately control the pulling speed of the first input assembly and the damping force of the first output assembly by using the above structure, ensure the stable transmission and accurate control of the base material on the production line, thereby improving the production efficiency. And it can ensure stable transmission speed and accurate process control, which helps to reduce quality problems caused by sudden speed changes or equipment failures, improve the quality and consistency of the final product, reduce material waste and defective rate, and reduce production cost. The design of the buffer assembly and the damping roller group makes the production line flexible to respond to the speed difference and production rhythm change between different process steps, improving the adaptability and flexibility of the production line.

[0039] According to the production line of the handbag provided by the present application, the driving roller in the first traction conveying roller group is rotationally connected to the rack, the driven roller in the first traction conveying roller group is rotationally and movably connected to the rack, at least one of the two rollers of the damping roller group is rotationally and movably connected to the rack, and the end of the driven roller in the first traction conveying roller group and the end of at least one of the rollers are provided with an adjusting handle.

[0040] By adopting the above technical scheme, the driven roller is rotationally and movably connected to the rack, allowing the operator to adjust the position of the driven roller according to production needs. This adjustment can optimize the tension and position of the base material during conveying, ensuring that the base material remains stable during transmission and reducing the risk of wrinkles or deviation.

[0041] Further, at least one of the rollers of the damping roller group is rotationally and movably connected to the rack, which also allows the size and position of the damping force to be adjusted according to production needs. By adjusting the position of the damping roller, the speed and stability of the base material during output can be accurately controlled, ensuring smooth connection with subsequent process steps.

[0042] In use, since the driven roller and the damping roller are both adjustable, when the production line needs to be adjusted to accommodate base materials of different specifications or materials, the driven roller or the damping roller can be adjusted to optimize the tension and stability of the base material during conveying, reducing production problems caused by base material relaxation or wrinkles. This process does not require downtime. This reduces the time wasted due to adjustments and improves production efficiency.

[0043] Further, the adjusting handle is provided at the end of the driven roller and the movable damping roller, so that the operator can complete the adjustment by simply rotating or pulling the handle. This design simplifies the operation process, reduces the difficulty and intensity of the operation. Moreover, the design of the adjusting handle allows the operator to intuitively see and adjust the position of the roller without the need for complex measurement and calculation. This improves the accuracy and efficiency of the operation and reduces production problems caused by misoperation.

[0044] According to the production line of the handbag provided by the application, the second input assembly comprises a second traction conveying roller set and a second driving component electrically connected with the control unit, the second buffer assembly comprises a plurality of second buffer rollers spaced apart in the height direction and rotationally connected to the rack, and the second output assembly comprises an adjusting roller sliding along the height direction of the rack and rotationally connected to the rack.

[0045] The second driving component is fixedly connected to the rack, and the output shaft of the second driving component is in transmission connection with the driving roller in the second traction conveying roller set. The base material is clamped between the driving roller and the driven roller in the second traction conveying roller set through the base material clamping device of the handle fixing device. The control unit controls the second driving component to drive the driving roller to rotate and interact with the driven roller to pull the base material every time interval. The base material is pulled to the second buffer assembly by the second traction conveying roller set and is sequentially wound around the plurality of second buffer rollers and passes through the adjusting roller. The adjusting roller moves in the height direction of the rack to adjust the tension of the base material on both sides of the adjusting roller.

[0046] According to the above technical scheme, the second driving component is electrically connected with the control unit, which can receive accurate instructions from the control unit to drive the driving roller to rotate every time interval. This accurate time control ensures that the base material can be pulled to the next process step according to the predetermined rhythm after the handle fixing device is processed, improving the synchronization and efficiency of the production line. The driving roller and the driven roller in the second traction conveying roller set interact by clamping the base material, which ensures that the base material is stable during transmission. This design reduces production interruptions and quality problems caused by base material deviation or falling.

[0047] Further, the plurality of second buffer rollers spaced apart in the height direction provide a temporary storage and buffer area for the base material. When the second traction conveying roller set pulls the base material at a certain time interval, the base material can be sequentially wound around the plurality of buffer rollers, which helps to smooth the transmission speed of the base material and reduces the impact on the subsequent process steps caused by sudden changes in speed.

[0048] Further, the adjusting roller slides along the height direction of the rack and is rotationally connected to the rack, which can adjust the tension of the base material on both sides of the adjusting roller and can adjust the tension state of the base material in real time according to production needs, ensuring that the base material maintains appropriate tension during transmission, reducing wrinkles or slack, and improving product quality. During use, by adjusting the position of the adjusting roller, different specifications, materials or thicknesses of the base material can be adapted to ensure that the production line can flexibly respond to various production needs.

[0049] Therefore, the production line of the handbag provided by the application can utilize time control, stable base material transmission, efficient buffering and adjustment, and reduced manual intervention, thereby improving the production efficiency and product quality of the handbag production line, ensuring the stability and consistency of the base material during the transmission process, and reducing production problems caused by sudden speed changes, insufficient tension, or excessive tension.

[0050] According to the production line of the handbag provided by the application, the conveying assembly comprises a first conveying component and a second conveying component connected end to end and electrically connected to the control unit respectively, wherein,

[0051] The input end of the first conveying component is connected to the downstream side of the adjustment roller, the output end of the first conveying component extends along the production line direction and passes through the forming device, and the control unit controls the first conveying component to convey the base material to the cutting device every interval of the second time threshold value;

[0052] The input end of the second conveying component is connected to the output end of the first conveying component, and the output end of the second conveying component extends to the forming device, and the control unit controls the second conveying component to convey the sheet material unit to the forming device every interval of the third time threshold value.

[0053] By controlling the first conveying component and the second conveying component by the control unit, the precise time interval management of the base material conveying process can be realized. The first conveying component conveys the base material to the cutting device every interval of the second time threshold value, and the second conveying component conveys the sheet material unit to the forming device every interval of the third time threshold value. This phased time control ensures the coordination and synchronization between the process steps on the production line.

[0054] In addition, the first conveying component and the second conveying component are connected end to end to form a continuous conveying channel, reducing the pause and waiting time of the base material during the conveying process. This continuous conveying method improves the overall efficiency of the production line, so that the base material can pass through each process step faster to complete the production of the final product.

[0055] In use, although the first conveying component and the second conveying component jointly constitute a continuous conveying system, they are respectively responsible for different process stages. The first conveying component conveys the base material to the cutting device for cutting processing, and the second conveying component conveys the cut sheet material unit to the forming device for forming. This segmented processing method makes the connection between process steps smoother, reduces production problems caused by process conflicts or interference, helps to reduce waste or damage of the base material caused by conveying errors, and improves the utilization rate of raw materials and the qualified rate of the final product.

[0056] According to the production line of the handbag provided by the application, the second output assembly further comprises an adjusting drive arranged on the rack at one end of the adjusting roller, a power output end of the adjusting drive is in transmission connection with one end of the adjusting roller, and the adjusting drive is in electrical connection with the control unit.

[0057] The control unit controls the adjusting drive to drive the adjusting roller to adjust the height according to a difference between the first time threshold and the second time threshold.

[0058] According to the technical scheme, the control unit can calculate and respond to the difference between the first time threshold (i.e., the time interval at which the second traction roller set pulls the base material) and the second time threshold (i.e., the time interval at which the first conveying component conveys the base material to the cutting device) in real time. Through the difference, the control unit can accurately control the action of the adjusting drive, so as to dynamically adjust the height of the adjusting roller. The automatic adjustment mechanism ensures that the base material always maintains appropriate tension during transmission between different process steps. Compared with the traditional tension adjustment which often depends on the experience and judgment of operators and is easily affected by human factors, the adjustment mechanism provided by the application can reduce human errors and improve the stability and reliability of the production line.

[0059] In addition, the height adjustment of the adjusting roller in combination with the control of the first and second time thresholds makes the entire production process more synchronized and coordinated, which helps to reduce production interruptions and quality problems caused by speed mismatching or insufficient tension.

[0060] According to the production line of the handbag provided by the application, the adjusting height of the adjusting roller is calculated according to the following method:

[0061] h==V1(T-t1)-V2(T-t2); wherein,

[0062] h is the adjusting height of the adjusting roller;

[0063] V1 is the linear speed of the driving roller in the second traction roller set;

[0064] V2 is the conveying speed of the first conveying component;

[0065] T is a unit time constant;

[0066] t1 is the first time threshold;

[0067] t2 is the second time threshold.

[0068] According to the production line of the handbag provided by the application, the adjusting roller is located above the second buffer roller in the height direction of the rack; and,

[0069] When the adjustment height h of the adjustment roller is greater than 0, the control unit controls the adjustment drive to drive the adjustment roller to move upward along the height direction of the rack by a distance h.

[0070] When the adjustment height h of the adjustment roller is less than 0, the control unit controls the adjustment drive to drive the adjustment roller to move downward along the height direction of the rack by a distance h.

[0071] By controlling the up-and-down movement of the adjustment roller, the tension of the base material on both sides of the adjustment roller can be accurately controlled. When the tension needs to be increased, the control unit drives the adjustment roller to move upward, so that the base material receives greater stretching force during transmission. Conversely, when the tension needs to be reduced, the adjustment roller moves downward to reduce the stretching force. This dynamic adjustment ensures smooth transmission of the base material between different process steps.

[0072] In addition, since the adjustment roller can be adjusted in height in real time as needed, production interruptions and quality problems caused by fluctuations in the tension of the base material can be effectively reduced, which helps to improve the overall efficiency and reliability of the production line.

[0073] In addition, the precise adjustment of the adjustment roller can ensure that the base material can smoothly pass through each roller group during transmission, reducing production delays caused by jamming or slipping. It also helps to maintain the flatness and consistency of the base material, providing a good foundation for subsequent cutting and molding processes.

[0074] According to the production line of the handbag provided by the application, the first conveying component and the second conveying component include at least one of a conveying roller, a conveying belt, a conveying suction cup, and a conveying tray, and respectively include a first drive and a second drive for driving the respective conveyance, the first drive and the second drive include a stepper motor, the control unit acquires the rotation speed of the first drive and the second drive in real time, and acquires the conveying speed of the first conveying component and the second conveying component in real time.

[0075] By using the above technical solution, the stepper motor realizes rotation by controlling the pulse of the current, and the motor completes one step of rotation for each received pulse. The speed control is very accurate, and the rotation speed can be accurately adjusted according to the instructions of the control unit. The control unit can acquire the rotation speed of the stepper motor in real time, so as to ensure that the conveying speed of the conveying component always remains within a predetermined range, avoiding production problems caused by speed fluctuations.

[0076] In addition, the conveying components such as the conveying belt, the conveying suction cup, or the conveying tray can continuously and stably convey the base material, reducing production delays caused by interruptions in conveying. Through the synchronous control of the control unit on the first conveying component and the second conveying component, it can be ensured that the base material always remains coordinated and consistent during transmission between different process steps, thereby improving the overall efficiency and stability of the production line.

[0077] In use, the rotation speed of the stepping motor can be adjusted according to production requirements, so that the production line can adapt to different specifications, materials or production speeds. When there are changes in speed, changes in base material specifications or equipment failures on the production line, the control unit can automatically adjust the rotation speed of the stepping motor and the conveying speed of the conveying component according to the actual situation to adapt to production changes.

[0078] According to the production line of the handbag provided by the application, the packing device comprises a bag folding unit, a bag arranging unit and a packaging unit arranged in sequence in the direction of the production line. The conveying device further comprises a first packing conveying component arranged in the horizontal direction, a second packing conveying component extending in the vertical direction, and a third packing conveying component extending in the horizontal direction, and the extension direction of the third packing conveying component is perpendicular to the extension direction of the first packing conveying component.

[0079] The bag folding unit comprises a pressing component arranged above the first packing conveying component and side inserting components arranged on both sides of the first packing conveying component in the width direction, and the input end of the first packing conveying component extends at least below the forming device. The input end of the second packing conveying component at least partially overlaps the output end of the first packing conveying component in the vertical direction, and the input end of the second packing conveying component is lower than the output end of the first packing conveying component in the vertical direction. The bag arranging unit comprises a receiving component arranged at the output end of the second packing conveying component, which collects handbags in a preset number, and the receiving component comprises a movable baffle arranged in the horizontal direction. The packaging unit is arranged at the output end of the second packing conveying component.

[0080] The above technical scheme realizes automation from bag folding, bag arranging to packaging, reduces manual intervention, and improves production efficiency and consistency. The design of the first packing conveying component, the second packing conveying component and the third packing conveying component ensures smooth connection between handbags in different processing stages. The pressing component arranged above the first packing conveying component can accurately press the handbags to make their shape regular, which is convenient for subsequent packaging. The side inserting components on both sides of the first packing conveying component help to further arrange the side edges of the handbags to ensure their flatness. Collecting handbags in a preset number and using a movable baffle to arrange them in batches provides convenience for subsequent packaging.

[0081] In addition, the vertical extension design of the second packing conveying component and the perpendicular extension direction design of the third packing conveying component and the first packing conveying component not only make the whole packing device more compact in space utilization and reduce the occupied area, but also make the handbags arranged in the vertical direction, which is more conducive to the neatness of the bag arranging.

[0082] According to the production line of the handbag provided by the application, the conveying device further comprises a transfer component arranged between the bag arranging unit and the packaging unit, and the control unit is electrically connected to the first packaging conveying component, the second packaging conveying component, the third packaging conveying component and the transfer component respectively; wherein,

[0084] V3 and N are calculated according to the following manner:

[0085] V3 == L*n / T;

[0086] N == L*n / m; wherein,

[0087] L is the length of the handbag;

[0088] n is the sealing frequency of the forming device;

[0089] T is a constant per unit time;

[0090] m is the preset number of the handbags per group.

[0091] According to the production line of the handbag provided by the application, the forming device comprises a forming die and a fusing component movably arranged on the side of the forming die, the first packaging conveying component comprises a conveying belt, the input end of the conveying belt is located below the forming die, the output end of the conveying belt extends to the packaging device, the sheet material unit is wound to the outer periphery of the forming die, the fusing component moves towards the forming die to fuse the side edges of the sheet material unit wound to the outer periphery of the forming die to form the handbag, and the handbag formed outside the forming die falls to the first packaging conveying component.

[0092] By adopting the above technical scheme, the forming die provides a basic shape profile for the handbag, and the movably arranged fusing component is responsible for fusing the side edges of the sheet material unit wound to the outer periphery of the die to form a complete handbag. This design ensures the rapid and accurate forming of the handbag. The input end of the first packaging conveying component (conveying belt) is located below the forming die, which not only can timely receive and convey the formed handbag, but also can make the handbag fall to the first packaging conveying component under the action of gravity, without the need to arrange an additional transfer structure, which is beneficial to simplify the structure of the production line, the output end of the conveying belt extends to the packaging device, which provides seamless connection for the subsequent packaging process, and realizes continuous production of the handbag.

[0115] Specifically, in the production line provided by the application, the base material processing device 100 is used to fold the edges of the base material and intermittently glue the edges of at least one side of the base material at a first preset interval along the length direction of the base material; the handle fixing device 200 fixes handles at the edges of both sides of the base material at a second preset interval along the length direction of the base material; the cutting device 300 cuts the base material with handles to form a plurality of piece units along the width direction of the base material; the forming device 400 seals each piece unit to form a handbag; the packaging device 500 packs the handbags in a preset number as a group; and the conveying device extends along the production line direction and sequentially passes through the base material processing device 100, the handle fixing device 200, the cutting device 300, the forming device 400 and the packaging device 500.

[0116] Further, the conveying device comprises a first speed matching unit 600 arranged between the base material processing device 100 and the handle fixing device 200, a second speed matching unit 700 arranged between the handle fixing device 200 and the cutting device 300, and a third speed matching unit 800 arranged between the cutting device 300 and the forming device 400; and a control unit 900 electrically connected with the first speed matching unit 600, the second speed matching unit 700 and the third speed matching unit 800 respectively.

[0117] In use, the control unit 900 controls the first speed matching unit 600 to input the base material at a first speed, and to convey the base material to the handle fixing device 200 at every first time threshold, the first time threshold being determined according to the fixing frequency of the handle; the control unit 900 controls the second speed matching unit 700 to input the base material at every first time threshold, and to convey the base material to the cutting device 300 at every second time threshold, the second time threshold being determined according to the cutting frequency of the cutting device 300; and the control unit 900 controls the third speed matching unit 800 to input the base material at every second time threshold, and to convey the base material to the forming device 400 at every third time threshold, the third time threshold being determined according to the sealing frequency of the forming device 400.

[0118] It should be understood that the production line of the handbag provided by the present application is not limited to the type of handbag produced, such as non-woven fabric handbag, plastic bag, high molecular fiber material handbag, spacer fabric handbag, high molecular fiber material handbag, etc.

[0119] It should be further understood that in the present application, the base material is in a rolled state when stored, and the base material is in a flat state during conveying.

[0120] The structure of the base material processing device 100 is not limited, as shown in FIG. 7, which can be a device comprising a folding mechanism 110 and a glue mechanism 120. The folding mechanism 110 can be used to fold the edges of the base material, and the glue mechanism 120 can be used to paste double-sided tape on the folded edge of the base material. The folding mechanism 110 can be a folding plate arranged on the rack 10 and located on both sides of the base material. When the base material passes through the folding plate, the folding plate extrudes the edges of the base material to achieve the folding process.

[0121] The glue mechanism 120 comprises a shelf for storing adhesive tape and a guide structure. The adhesive tape stored in the shelf can be guided to the folded edge of the base material by the guide structure and pasted on the folded edge of the base material intermittently.

[0122] Further, the gluing mechanism 120 is also provided with a cutting mechanism and a length detecting mechanism (not shown), the cutting mechanism can be a cutter for example, the length detecting mechanism can be a laser sensor, and the cutting mechanism and the laser sensor are electrically connected with the control unit 900. In use, when the laser sensor detects that the adhesive tape reaches a predetermined length, for example, 50mm, the detected length information is transmitted to the control unit 900, and the control unit 900 cuts the adhesive tape according to the length information, and controls the guide roller on the guide structure to extrude it at the folded edge of the base material.

[0123] Further, the width of the folded edge of the base material is not limited, for example, it can be 5mm, 8mm, 10mm, etc., and in use, the width of the folded edge of the base material can be adjusted by adjusting the position of the folding plate.

[0124] Further, in the present application, the material of the handle of the shopping bag and the base material is not limited, for example, it can be non-woven fabric, plastic, polypropylene synthetic material, etc., which can facilitate heat sealing.

[0125] Taking the handle of the shopping bag and the base material as non-woven fabric for example, the handle fixing device 200 in the present application adopts a handle sealer.

[0126] Specifically, the specific structure of the handle sealer is not limited, and in one example, as shown in FIG. 8, the handle fixing device 200 includes a heat sealing head 220 and a handle supply mechanism 210, and the heat sealing head 220 and the handle supply mechanism 210 are electrically connected to the control unit 900; in use, the handle supply mechanism 210 transports the handle to the position of the heat sealing head 220 of the handle sealer, the conveying device transports the base material to the position of the heat sealing head 220 of the handle sealer, and the heat sealing head 220 is used to seal the two end portions of the handle to the folded edge of the base material.

[0127] The structure of the cutting device 300 is not limited, and in one example, as shown in FIG. 9, the cutting device 300 includes a cutting frame 320 and a cutter 310 movably arranged on the cutting frame 320, and a laser sensor (not shown) is arranged on the cutting frame 320.

[0128] Specifically, the cutter 310 can be movably connected to the cutting frame 320 by a two-dimensional motion mechanism, which is a mechanism that can move in the horizontal plane, for example, two mutually staggered electric sliding rails are arranged. The electric sliding rails and the laser sensor are electrically connected to the control unit 900.

[0129] In use, the feeding length of the base material is detected by the laser sensor, the length information is detected by the laser sensor and transmitted to the control unit 900, and when the control unit 900 judges that the feeding length of the base material reaches the required length according to the length information, for example, reaches the sum of the width and the thickness of the bag, the control unit 900 controls the electric sliding rails to drive the cutter 310 to move and cut out the sheet material unit.

[0130] The structure of the forming device 400 is not limited. Taking the manufacture of the non-woven fabric bag as an example, as shown in FIG. 10, the forming device 400 includes a forming die 410 and a fusing component 420 arranged on both sides of the die. The fusing component 420 includes a hot-seal head in the shape of a large character or a character and a driving member for driving the hot-seal head to approach or move away from the forming die 410. The driving member is electrically connected with the control unit 900. When the sheet material unit is conveyed and wrapped onto the die, the control unit 900 controls the driving member to drive the hot-seal heads on both sides to approach the die, so as to fuse the base material on the forming die 410, so that the two sides of the tote bag are sealed, thereby forming a complete tote bag.

[0131] It is further understood that the forming die 410 is further provided with a driving member for driving it to ascend and descend. The driving member is electrically connected with the control unit 900. When the sheet material unit is conveyed below the forming die 410, the control unit 900 controls the driving member to drive the forming die 410 to descend, so that the sheet material unit is wrapped onto the forming die 410.

[0132] The structure of the packing device 500 is not limited. In an example, as shown in FIG. 11, the packing device 500 includes a bag folding unit 510, a bag arranging unit 520 and a packaging unit 530 arranged in sequence along the production line. The bag folding unit 510 has a compression roller and a conveying channel. When the formed tote bag passes through the conveying channel, the compression roller located at the upper part of the conveying channel gradually compresses the tote bag, so that the tote bag is gradually in a flat posture. After the compressed tote bag enters the bag arranging unit 520, the bag arranging unit 520 groups and arranges the conveyed tote bags in groups, for example, 10 bags per group. Each group of the arranged tote bags is transferred to the packaging unit 530. The packaging unit 530 can bundle each group of the tote bags, thereby realizing the packing process of the tote bags.

[0133] It is understood that the bag arranging unit 520 can arrange the tote bags in a vertical posture as a whole, which is beneficial to the integrity of each group of the tote bags.

[0134] It is further understood that the above-mentioned base material processing device 100, handle fixing device 200, cutting device 300, forming device 400 and packing device 500 in the present application include a plurality of driving members. The driving members can be motors, air cylinders or hydraulic cylinders. The embodiments of the present application do not make one-by-one description.

[0135] Furthermore, in the present application, only part of the structure of the base material processing device 100, handle fixing device 200, cutting device 300, forming device 400 and packing device 500 is shown. In actual design, other structures can also be arranged according to actual needs, as long as the action functions required above can be realized, which does not deviate from the scope of the present application.

[0136] It is further understood that the structure of the control unit 900 is not limited, for example, it can be a controller or an integrated control cabinet.

[0137] Regarding the production line of the handbag provided by the application, the base material can be folded and glued by using the base material processing device 100, the handle can be fixed to the two side folds of the base material by using the handle fixing device 200, the base material with the handle can be cut into multiple piece units by using the cutting device 300, and each piece unit can be formed into a handbag by using the forming device 400. The base material or the piece unit can be conveyed to the required station by using the conveying device, and the corresponding bag-making action can be performed by the corresponding device, so as to realize the whole handbag production.

[0138] In actual production of handbags, for some large batch orders with relatively urgent time, not only the stability of the production line needs to be ensured, but also the production efficiency needs to be ensured. The production line of the handbag provided by the application is provided with the first speed matching unit 600 between the base material processing device 100 and the handle fixing device 200, the second speed matching unit 700 between the handle fixing device 200 and the cutting device 300, and the third speed matching unit 800 between the cutting device 300 and the forming device 400. When in use, even if the feeding speeds of the base material processing device 100 and the handle fixing device 200 are inconsistent, the feeding speeds of the handle fixing device 200 and the cutting device 300 are inconsistent, and the feeding speeds of the cutting device 300 and the forming device 400 are inconsistent, the first, second and third speed matching units can ensure that the transmission speed and time of the base material between different devices can be accurately adjusted, so that the production line can be smoothly and efficiently operated, and the problem of the base material being torn or accumulated due to speed difference can be prevented. Not only the stability of the whole production line can be ensured, but also the production efficiency of the production line can be improved.

[0139] In addition, since the feeding speed of each process step (such as folding, gluing, fixing handle, cutting and sealing) can be accurately controlled and seamlessly connected between steps, the quality problems caused by improper operation or time delay are reduced. For example, the fixing position of the handle and the cutting accuracy can be ensured, and the finally generated handbag is more consistent and reliable in appearance and functionality.

[0140] In addition, the automatic speed matching and time control reduces human errors and interventions, reduces the rate of defective products, thereby saving production costs, and the packaging device 500 packs the handbags in a preset number, which is convenient for subsequent inventory management and logistics transportation.

[0141] When in use, the speed matching units and the time threshold adjustment can be controlled by the control unit 900, so that the production line can be quickly adjusted according to the requirements of different specifications and types of handbag, so that the production line can adapt to diversified production requirements, and the utilization rate and applicability of the production line can be improved.

[0142] Further, the handbag production line provided by the application reduces the direct contact of workers with dangerous machinery, ensures the safe operation of the production process, and reduces the risk of injury.

[0143] In summary, the handbag production line provided by the application can realize the matching of the feeding speed of the base material between different processes on the basis of ensuring the stability and safety of the production line, improve the continuity of the production line during work, and make the production line run smoothly and efficiently, thereby improving the production efficiency of the handbag production line.

[0144] It should be understood that the specific values of the first speed, the first time threshold, the second time threshold and the third time threshold are not limited and should be determined according to production requirements.

[0145] The first speed matching unit 600, the second speed matching unit 700 and the third speed matching unit 800 in the application will be described in detail as follows:

[0146] In an implementable embodiment, as shown in FIGS. 3, 4-6 and 12, the first speed matching unit 600 includes a first input assembly 610 arranged on the rack 10 on the upstream side and a first output assembly 620 arranged on the rack 10 on the downstream side, the first input assembly 610 is electrically connected with the control unit 900, and a first buffer assembly 630 is further arranged between the first input assembly 610 and the first output assembly 620; the second speed matching unit 700 includes a second input assembly 710 arranged on the rack 10 on the upstream side and a second output assembly 720 arranged on the rack 10 on the downstream side, the second input assembly 710 is electrically connected with the control unit 900, and a second buffer assembly 730 is further arranged between the second input assembly 710 and the second output assembly 720; the third speed matching unit 800 includes a conveying assembly 810.

[0147] The control unit 900 controls the first input assembly 610 to pull the base material from the base material storage position at the first speed and through the base material processing device 100 to the first buffer assembly 630, and the base material extends to the first output assembly 620 through the first buffer assembly 630.

[0148] When in use, the control unit 900 controls the second input assembly 710 to pull the base material from the first output assembly 620 and through the handle fixing device 200 to the second buffer assembly 730 every first time threshold, and the base material extends to the second output assembly 720 through the second buffer assembly 730, and the second output assembly 720 delivers the base material to the base material inlet of the conveying assembly 810 with a second time threshold, and the sheet material units through the base material outlet of the conveying assembly 810 are respectively delivered to the forming device 400 every third time threshold.

[0149] Based on the above structure, the base material is pulled from the base material storage site by the first input assembly 610 at a constant speed (first speed) and processed through the base material processing device 100. Then, the base material enters the first buffer assembly 630, which serves as a temporary storage area, can smoothly adjust the flow speed of the base material, and can reduce production interruptions caused by sudden speed changes or equipment failures. When the first output assembly 620 needs to output, the base material is stably output from the buffer assembly, ensuring the smooth progress of the subsequent process. The second input assembly 710 pulls the base material from the first output assembly 620 every first time threshold (matching the handle fixing frequency) according to the instruction of the control unit 900, and enters the second buffer assembly 730 after being processed through the handle fixing device 200. This design allows the base material to maintain stable flow during handle fixing, while reducing waiting time and improving production efficiency. The second output assembly 720 delivers the base material to the conveying assembly 810 according to the cutting frequency (second time threshold), preparing for the next process. And through this scheme, even for the base material of the handbag which is easy to bend, it can also ensure that it is delivered in a tensioned state at different conveying speeds, thereby ensuring the stability of the production line during production.

[0150] Further, the setting of the buffer assembly enables the production line to flexibly respond to the speed difference and production rhythm change between different process steps. When a certain process step (such as handle fixing) requires a longer time, the buffer assembly can store excess base material to avoid waiting for the upstream equipment to stop; when the downstream equipment (such as the cutting device 300) is ready, the buffer assembly can quickly release the base material to ensure the continuous operation of the production line. This design effectively reduces production interruptions and material waste caused by speed mismatch.

[0151] Further, by precisely controlling the output time threshold (first time threshold, second time threshold) of each speed matching unit, it can ensure that each process step is carried out under optimal conditions. For example, the handle fixing device 200 has enough time to firmly fix the handle on the base material, and the cutting device 300 can also cut at the correct position. This helps to improve the quality and consistency of the final product and reduce the rate of defective products.

[0152] Further, the whole speed matching and conveying process can be automatically controlled by the control unit 900, reducing the need for manual intervention. This not only reduces labor intensity, but also improves the automation level and stability of the production line. The automatic control system can also make corresponding adjustments according to the production state to ensure smooth operation of the production line.

[0153] The first input component 610 and the first output component 620 will be described in detail below:

[0154] In an implementable embodiment, as shown in FIG. 4, the first input component 610 includes a first traction conveying roller set 611 and a first driving component (not shown), the first driving component is electrically connected with the control unit 900, the first buffer component 630 includes a plurality of first buffer rollers 631 spaced in the height direction and rotatably connected to the rack 10, and the first output component 620 includes a damping roller set 621.

[0155] The structure of the first driving component is not limited, for example, it can be a driving component such as a stepper motor, a hydraulic motor, etc.

[0156] Further, the first driving component is fixedly connected to the rack 10, and the output shaft of the first driving component is drivingly connected with a driving roller in the first traction conveying roller set 611, the base material clamped by the base material handling device 100 is arranged between the driving roller and a driven roller in the first traction conveying roller set 611, the control unit 900 controls the first driving component to drive the driving roller to rotate and interact with the driven roller to pull the base material at a first speed, the base material pulled by the first traction conveying roller set 611 through the base material handling device 100 is sequentially wound around the plurality of first buffer rollers 631 and then passes between the two rollers of the damping roller set 621, and the two rollers of the damping roller set 621 have a damping force for the movement of the base material in the production line direction.

[0157] The number of first buffer rollers 631 is not limited, for example, it can be set to 5, 6, 7, or other numbers, it should be understood that the plurality of first buffer rollers 631 can be arranged in a manner that the heights are not flat in the height direction, which is beneficial to improve the buffer amount of the base material in the first buffer component 630.

[0158] Based on the above structure, the first driving component is electrically connected with the control unit 900 and can receive instructions from the control unit 900 to accurately control the rotating speed of the driving roller in the first traction conveying roller group 611, so as to pull the base material at a first speed. The driving roller interacts with the driven roller to ensure that the base material is stable during transmission and does not slip, thereby reducing production interruptions and quality problems caused by base material deviation or falling. The plurality of first buffer rollers 631 arranged at intervals in the height direction provide a temporary storage and buffer area for the base material. When the first traction conveying roller group 611 pulls the base material at a constant speed, the base material can be wound around the plurality of buffer rollers in turn, which helps to smooth the transmission speed of the base material and reduce the impact on subsequent process steps caused by sudden speed changes.

[0159] Further, the design of the buffer roller enables the production line to flexibly cope with the speed difference between different process steps. When a certain process step needs a longer time for processing (such as the base material processing device 100), the buffer roller can store excess base material to avoid downtime of the upstream equipment; when the downstream equipment (such as the first output assembly 620) is ready, the buffer roller can release the base material to ensure continuous operation of the production line.

[0160] Further, the two rollers of the damping roller group 621 generate a damping force on the movement of the base material in the production line direction. The damping effect helps to further stabilize the transmission speed of the base material and reduce production problems caused by excessive or insufficient speed. At the same time, the damping roller can also absorb vibrations and shocks during the transmission of the base material to protect the production line equipment.

[0161] Further, the damping roller group 621 is connected with the first buffer assembly 630, and the speed and time interval of the base material output from the first buffer assembly 630 to the next process step (such as the handle fixing device 200) can be accurately controlled by adjusting the size of the damping force during use. This helps to maintain the stability and synchronization of the production line and improve production efficiency.

[0162] Therefore, the production line of the handbag provided by the present application can accurately control the pulling speed of the first input assembly 610 and the damping force of the first output assembly 620 by using the above structure, thereby ensuring stable transmission and accurate control of the base material on the production line, improving production efficiency. And it can ensure stable transmission speed and accurate process control, which helps to reduce quality problems caused by sudden speed changes or equipment failures, improve the quality and consistency of the final product, reduce material waste and defective rate, and reduce production cost. The design of the buffer assembly and the damping roller group 621 enables the production line to flexibly cope with the speed difference and production rhythm change between different process steps, improving the adaptability and flexibility of the production line.

[0163] The structure and arrangement of the first traction conveying roller group 611 are not limited.

[0164] In an implementable embodiment, as shown in FIG. 4, the driving rollers in the first traction conveying roller set 611 are rotationally connected to the frame 10, the driven rollers in the first traction conveying roller set 611 are rotationally and movably connected to the frame 10, at least one of the two rollers in the damping roller set 621 is rotationally and movably connected to the frame 10, and the ends of the driven rollers in the first traction conveying roller set 611 and the ends of the at least one roller are provided with adjusting handles (not shown).

[0165] The damping roller set 621 can be connected to the frame 10 in various ways. For example, one of the two rollers can be rotationally and movably connected to the frame 10, and the other can be rotationally connected to the frame 10. Alternatively, both rollers can be rotationally and movably connected to the frame 10.

[0166] It should be understood that when the rollers in the damping roller set 621 are connected, a sliding groove can be provided on the frame 10, the ends of the rollers in the damping roller set 621 are inserted into the sliding groove and rotationally connected to the sliding groove, and the ends of the rollers are provided with locking pins. After the rollers are adjusted to the target position, the locking pins are used to limit the rotation of the rollers at the target position.

[0167] When the driven rollers in the first traction conveying roller set 611 are connected, a sliding groove can be provided on the frame 10, the driven rollers in the first traction conveying roller set 611 are inserted into the sliding groove and rotationally connected to the sliding groove, and the ends of the driven rollers in the first traction conveying roller set 611 are provided with locking pins. After the driven rollers in the first traction conveying roller set 611 are adjusted to the target position, the locking pins are used to limit the rotation of the driven rollers at the target position.

[0168] It should be further understood that the ends of the driven rollers in the first traction conveying roller set 611 and the rollers in the damping roller set 621 are connected to the sliding groove through bearings, and the locking pins act on the bearing seats of the bearings.

[0169] Further, the driven rollers in the first traction conveying roller set 611 and one of the rollers in the damping roller set 621 are also provided with adjusting handles, which are operated when adjusting the positions of the rollers.

[0170] Based on the above structure, the driven rollers are rotationally and movably connected to the frame 10, allowing the operator to adjust the positions of the driven rollers according to production needs. Such adjustment can optimize the tension and position of the base material during conveying, ensuring that the base material remains stable during transmission and reducing the risk of wrinkles or deviation.

[0171] Further, at least one of the rollers in the damping roller set 621 is rotationally and movably connected to the frame 10, which also allows the size and position of the damping force to be adjusted according to production needs. By adjusting the position of the damping roller, not only can the speed and stability of the base material during output be accurately controlled to ensure smooth connection with subsequent process steps, but also the material can be discharged more conveniently.

[0172] In use, as both the driven roller and the damping roller are movable and adjustable, when the production line needs to be adjusted to adapt to different specifications or materials of the base material, the tension and stability of the base material during conveying can be optimized by adjusting the driven roller or the damping roller, reducing production problems caused by relaxation or wrinkles of the base material, without stopping the process. This reduces the time wasted due to adjustment and improves production efficiency.

[0173] Further, adjustment handles are provided at the ends of the driven roller and the movable damping roller, so that the operator can complete the adjustment through simple rotating or pushing and pulling actions. This design simplifies the operation process, reduces the operation difficulty and labor intensity. Moreover, the design of the adjustment handle allows the operator to intuitively see and adjust the position of the roller without complex measurement and calculation. This improves the accuracy and efficiency of the operation and reduces production problems caused by misoperation.

[0174] Further, the movable design makes it easier to disassemble and install the driven roller and the damping roller from the production line. This facilitates daily cleaning and maintenance of the equipment and prolongs the service life of the equipment.

[0175] Further, during later maintenance and repair, when parts such as bearings and seals of the driven roller or the damping roller need to be replaced, the movable design makes the replacement process faster and more convenient, reducing the downtime of the production line.

[0176] In summary, the handbag production line provided by the present application not only has good adaptability and flexibility, but also can improve production efficiency and product quality, simplify operation process and reduce labor intensity.

[0177] The second input assembly 710, the second buffer assembly 730 and the second output assembly 720 will be described in detail as follows:

[0178] In an implementable embodiment, as shown in FIG. 5, the second input assembly 710 includes a second traction conveying roller set 711 and a second driving component 712, the second driving component 712 is electrically connected with the control unit 900, the second buffer assembly 730 includes a plurality of second buffer rollers 731 which are spaced in the height direction and are rotationally connected to the rack 10, and the second output assembly 720 includes an adjusting roller 721 which slides along the height direction of the rack 10 and is rotationally connected to the rack 10.

[0179] Specifically, the second driving component 712 is fixedly connected to the rack 10, and the output shaft of the second driving component 712 is in transmission connection with the driving roller in the second traction conveying roller set 711, and is clamped between the driving roller and the driven roller in the second traction conveying roller set 711 via the base of the handle fixing device 200. The control unit 900 controls the second driving component 712 to drive the driving roller to rotate and interact with the driven roller to pull the base every first time threshold. The base pulled by the second traction conveying roller set 711 via the handle fixing device 200 is pulled to the second buffer assembly 730 and is sequentially wound around the plurality of second buffer rollers 731 and passes through the adjusting roller 721. The adjusting roller 721 moves in the height direction of the rack 10 to adjust the tension of the base located on both sides of the adjusting roller 721.

[0180] It should be understood that the number of second buffer rollers 731 is not limited, for example, it can be set to 5, 6, 7, or other numbers. It should be understood that the plurality of second buffer rollers 731 can be arranged in a manner of uneven height in the height direction, which is beneficial to improve the buffering amount of the base in the first buffer assembly 630.

[0181] The structure of the second driving component 712 is not limited, for example, it can be set to a stepping motor, a hydraulic motor, or the like.

[0182] It should be further understood that the setting mode of the adjusting roller 721 is not limited. In one example, a sliding groove can be provided on the rack 10, the end of the adjusting roller 721 is inserted into the sliding groove and is rotationally connected in the sliding groove, and the end of the adjusting roller 721 is provided with a locking pin. After the adjusting roller 721 is adjusted to the target position, the locking pin is used to limit the rotation of the adjusting roller 721 at the target position.

[0183] Based on the above structure, the connection between the second driving component 712 and the control unit 900: the second driving component 712 is electrically connected with the control unit 900, and can receive accurate instructions from the control unit 900 to drive the driving roller to rotate every first time threshold. This accurate time control ensures that the base can be pulled to the next process step according to the predetermined rhythm after the handle fixing device 200 is processed, which improves the synchronization and efficiency of the production line.

[0184] Further, the driving roller and the driven roller interact by clamping the base, which can ensure that the base is stable and does not slip during transmission. This design reduces production interruptions and quality problems caused by base deviation or falling.

[0185] Further, the plurality of second buffer rollers 731 arranged at intervals in the height direction provide a temporary storage and buffering area for the base material. When the second traction roller set 711 pulls the base material at a certain time interval, the base material can be wound on the plurality of buffer rollers in turn, which helps to smooth the transmission speed of the base material and reduces the impact on subsequent process steps due to sudden changes in speed.

[0186] Further, the adjusting roller 721 is connected to the rack 10 by sliding and rotating along the height direction of the rack 10, and can adjust the tension of the base material on both sides. This design allows the operator to adjust the tension of the base material in real time according to production needs, ensuring that the base material maintains an appropriate tension during transmission, reducing wrinkles or slack, and improving product quality. By adjusting the position of the adjusting roller 721, different specifications, materials or thicknesses of the base material can be accommodated, ensuring that the production line can flexibly respond to various production needs.

[0187] The structure of the conveying assembly 810 is not limited, for example, it can be a conveyor belt, a conveying disc, etc.

[0188] In an implementable embodiment, as shown in FIG. 6, the conveying assembly 810 includes a first conveying component 811 and a second conveying component 812 connected end to end and respectively electrically connected to the control unit 900.

[0189] Specifically, the input end of the first conveying component 811 is connected to the downstream side of the adjusting roller 721, the output end of the first conveying component 811 extends along the production line direction and passes through the forming device 400, and the control unit 900 controls the first conveying component 811 to convey the base material to the cutting device 300 every second time threshold; the input end of the second conveying component 812 is connected to the output end of the first conveying component 811, and the output end of the second conveying component 812 extends to the forming device 400, and the control unit 900 controls the second conveying component 812 to convey the sheet material unit to the forming device 400 every third time threshold.

[0190] Based on the above structure, through the respective control of the first conveying component 811 and the second conveying component 812 by the control unit 900, precise time interval management of the base material conveying process is realized. The first conveying component 811 conveys the base material to the cutting device 300 every second time threshold, while the second conveying component 812 conveys the sheet material unit to the forming device 400 every third time threshold. This phased time control ensures the coordination and synchronization between the process steps on the production line, helps to reduce the waste or damage of the base material caused by conveying errors, and improves the utilization rate of raw materials and the qualified rate of the final product.

[0191] Furthermore, the first conveying component 811 and the second conveying component 812 are connected end to end to form a continuous conveying channel, reducing the downtime and waiting time of the base material during conveying, improving the overall efficiency of the production line, and enabling the base material to pass through each process step more quickly to complete the production of the final product.

[0192] Furthermore, although the first conveying component 811 and the second conveying component 812 collectively constitute a continuous conveying system, they are each responsible for a different process stage. The first conveying component 811 conveys the base material to the cutting device 300 for cutting processing, while the second conveying component 812 conveys the cut base material units to the forming device 400 for forming. This segmented processing approach makes the connection between process steps smoother, reducing production problems caused by process conflicts or interference.

[0193] Furthermore, the second time threshold and the third time threshold can be adjusted according to production requirements, enabling the production line to adapt to different specifications, materials, or production speeds, improving the versatility and adaptability of the production line.

[0194] Further, the second output assembly 720 further comprises an adjusting drive arranged on the rack 10 at one end of the adjusting roller 721, the power output end of the adjusting drive is in transmission connection with one end of the adjusting roller 721, and the adjusting drive is in electrical connection with the control unit 900. The control unit 900 controls the adjusting drive to drive the height of the adjusting roller 721 according to the difference between the first time threshold and the second time threshold.

[0195] It should be understood that the structure of the adjusting drive is not limited, for example, it can be an electric telescopic rod, a pneumatic cylinder, etc.

[0196] Based on the above structure, the control unit 900 can calculate and respond to the difference between the first time threshold (i.e., the time interval for the second traction conveying roller group 711 to pull the base material) and the second time threshold (i.e., the time interval for the first conveying component 811 to convey the base material to the cutting device 300). Through this difference, the control unit 900 can accurately control the action of the adjusting drive, thereby dynamically adjusting the height of the adjusting roller 721, ensuring that the base material maintains appropriate tension during transmission between different process steps.

[0197] Compared with the traditional tension adjustment which often relies on the experience and judgment of operators and is easily affected by human factors, through automatic adjustment, human error can be greatly reduced, and the stability and reliability of the production line can be improved.

[0198] Further, the height adjustment of the adjustment roller 721 is combined with the control of the first and second time thresholds, making the entire production process more synchronized and coordinated, which helps to reduce production interruptions and quality problems caused by speed mismatch or insufficient tension.

[0199] During use, when there are speed changes, base material specification changes, or equipment failures on the production line, the control unit 900 can automatically adjust the height of the adjustment roller 721 according to the actual situation to adapt to production changes. This flexibility ensures that the production line can maintain a high-efficiency and stable running state under various conditions.

[0200] In summary, by combining the adjustment drive with the adjustment roller 721 and controlling the height of the adjustment roller 721 according to the difference between the time thresholds through the control unit 900, not only is automatic tension adjustment achieved, but also the stability and reliability of the production line are improved, the production process is optimized, which in turn improves product quality and reduces maintenance costs, etc.

[0201] The adjustment height of the adjustment roller 721 is calculated as follows:

[0202] h = V1(T-t1) - V2(T-t2); where,

[0203] h is the adjustment height of the adjustment roller;

[0204] V1 is the linear speed of the driving roller in the second traction roller group;

[0205] V2 is the conveying speed of the first conveying component;

[0206] T is a unit time constant;

[0207] t1 is the first time threshold;

[0208] t2 is the second time threshold.

[0209] It should be understood that the specific value of the time constant T is not limited and can be set according to actual needs.

[0210] Further, the adjustment roller 721 is located above the second buffer roller 731 in the height direction of the rack 10.

[0211] Specifically, when the adjustment height h of the adjustment roller 721 is greater than 0, the control unit 900 controls the adjustment drive to drive the adjustment roller 721 to move upward in the height direction of the rack 10 by a distance h.

[0212] When the adjustment height h of the adjustment roller 721 is less than 0, the control unit 900 controls the adjustment drive to drive the adjustment roller 721 to move downward in the height direction of the rack 10 by a distance h.

[0213] Based on the above scheme, by controlling the up and down movement of the adjusting roller 721, the tension of the base material located on both sides of the adjusting roller 721 can be accurately controlled. When it is necessary to increase the tension, the control unit 900 drives the adjusting roller 721 to move upwards, so that the base material receives greater stretching force during transmission; on the contrary, when it is necessary to reduce the tension, the adjusting roller 721 moves downwards to reduce the stretching force. This dynamic adjustment ensures smooth transmission of the base material between different process steps.

[0214] Further, since the adjusting roller 721 can be adjusted in height in real time as needed, production interruptions and quality problems caused by fluctuations in base material tension can be effectively reduced, and the overall efficiency and reliability of the production line can be improved.

[0215] Further, the precise adjustment of the adjusting roller 721 allows the base material to smoothly pass around each roller set during transmission, reducing production delays caused by jamming or slipping, and helping to maintain the flatness and consistency of the base material, providing a good foundation for subsequent cutting and forming processes.

[0216] In use, the entire adjustment process is automatically controlled by the control unit 900 without human intervention, simplifying the operation process and reducing the difficulty and labor intensity of operation. At the same time, since the errors and faults caused by human factors are reduced, the maintenance cost is also reduced.

[0217] In summary, the adjusting roller 721 is designed above the second buffer roller 731 in the height direction of the rack 10, and the movement of the adjusting roller 721 in the height direction of the rack 10 is controlled according to the adjusting height of the adjusting roller 721, which brings precise tension control in the production line of the handbag, improves the stability, reliability, product quality of the production line, flexibly responds to production changes, and simplifies the operation and maintenance technical effects.

[0218] The structure of the first conveying member 811 and the second conveying member 812 is not limited, and can be at least one of a conveying roller, a conveying belt, a conveying suction cup, and a conveying tray, and respectively includes a first driving member and a second driving member for driving the respective conveyance, for example, the first conveying member 811 and the second conveying member 812 can be provided as a conveying belt, the first conveying member 811 includes a first driving member, and the second conveying member 812 includes a second driving member.

[0219] Further, the first driving member and the second driving member include a stepper motor, and the control unit 900 acquires the rotation speed of the first driving member and the second driving member in real time, and acquires the conveying speed of the first conveying member 811 and the second conveying member 812 in real time.

[0220] Based on the above design, the stepper motor realizes rotation by controlling the pulse of the current, and the motor completes a step rotation after receiving a pulse. This feature makes the stepper motor very accurate in speed control, and can achieve precise speed regulation according to the instructions of the control unit 900. Moreover, the control unit 900 can obtain the speed of the stepper motor in real time, which not only ensures that the conveying speed of the conveying component always remains within the predetermined range, avoids production problems caused by speed fluctuations, but also facilitates the operator to monitor the running state of the production line in real time.

[0221] The conveying component such as the conveying belt, the conveying suction cup or the conveying tray can continuously and stably convey the base material, reducing the production delay caused by the interruption of conveying, and maintaining the flatness and consistency of the base material, providing a good foundation for the subsequent cutting and forming processes.

[0222] When in use, the speed of the stepper motor can be adjusted according to production requirements, so that the production line can adapt to different specifications, materials or production speeds. When there are changes in speed, changes in base material specifications or equipment failures on the production line, the control unit 900 can automatically adjust the speed of the stepper motor and the conveying speed of the conveying component according to the actual situation to adapt to the production changes.

[0223] The above precise speed control and synchronous coordination reduce the waste or damage of the base material caused by conveying errors, and can improve the utilization rate of raw materials and the qualified rate of the final product.

[0224] Further, in the production line of the handbag, the stepper motor is used as the driving component, and the speed of the stepper motor and the conveying speed of the conveying component are obtained in real time, which not only realizes precise speed control, improves production efficiency and stability, but also flexibly responds to production changes, reduces energy consumption and noise, and improves product quality.

[0225] Further, in the present application, please refer to FIG. 3 and FIG. 11, the packaging device 500 includes a bag folding unit 510, a bag arranging unit 520 and a packaging unit 530 arranged in sequence in the direction of the production line, and the conveying device further includes a first packaging conveying component 511 arranged in the horizontal direction, a second packaging conveying component 521 extending in the vertical direction, and a third packaging conveying component 531 extending in the horizontal direction, and the extension direction of the third packaging conveying component 531 is perpendicular to the extension direction of the first packaging conveying component 511.

[0227] It should be understood that the input end of the first packing conveying component 511 can be directly below the forming device 400.

[0228] Based on the above structure, the production line can realize automation from bag folding, bag arranging to packaging, reduce manual intervention, and improve production efficiency and consistency.

[0229] Further, the ingenious design of the first packing conveying component 511, the second packing conveying component 521 and the third packing conveying component 531 ensures smooth connection between the handbags in different processing stages. The pressing component arranged above the first packing conveying component 511 can accurately press the handbags to make their shape regular, which is convenient for subsequent packaging. The side insertion components on both sides of the first packing conveying component 511 help to further arrange the side edges of the handbags, so that they can be folded inward. The receiving component 522 collects the handbags in a preset number, and through the movable baffle, the batch arrangement of the handbags is realized, which provides convenience for subsequent packaging. By moving the baffle, the number of collected handbags can also be adjusted according to actual needs, improving the flexibility of the production line.

[0230] Further, the vertical extension design of the second packing conveying component 521 and the design of the vertical extension direction of the third packing conveying component 531 and the first packing conveying component 511 not only make the whole packing device 500 more compact in space utilization, reduce the floor area, but also make the handbags arranged in a vertical posture, which is more conducive to the neatness of each group of handbags.

[0233] Taking the pressing plate as an example, the pressing plate can be arranged to extend in a gradually lowered posture from the entrance of the first packing conveying component 511 to the outlet direction, and when the tote bag enters the first packing conveying component 511, the tote bag can be gradually extruded due to the gradual extrusion of the pressing plate.

[0234] Taking the conveying belt as an example, the conveying belt is arranged above the first packing conveying component 511, and the conveying belt can extend in a gradually lowered posture from the entrance of the first packing conveying component 511 to the outlet direction, so that the conveying belt not only has the function of pressing the tote bag, but also can convey the tote bag by using the conveying belt.

[0237] The control unit 900 controls the operation of the first packing conveying component 511 and the operation speed of the second packing conveying component 521 is V3, and the conveying frequency of the third packing conveying component 531 and the transfer component 523 is N; wherein,

[0238] V3 and N are calculated according to the following manner:

[0239] V3 == L*n / T;

[0240] N == L*n / m; wherein,

[0241] L is the length of the tote bag;

[0242] n is the sealing frequency of the forming device;

[0243] T is a unit time constant;

[0244] m is the preset number of each group of tote bags.

[0245] It should be understood that the structure of the transfer component 523 is not limited, for example, it can be a mechanical hand, or a flipable frame, etc.

[0246] The sealing frequency of the forming device 400, the preset number of each group of handbags, and the unit time constant can be set according to actual inspection needs, and the present application does not make a unique requirement.

[0248] Based on this structure, the forming mold 410 provides a basic shape profile for the handbag, and the movably arranged fusing component 420 is responsible for fusing the side edges of the sheet material unit wound around the periphery of the mold to form a complete handbag. The input end of the first packing conveying component 511 (conveying belt) is located below the forming mold 410, which can timely receive and convey the formed handbag.
