[0023] refer to Figure 1-8 , a modular flexible shoemaking production line includes a plurality of stations arranged in an assembly line, each station has at least one station and is independently arranged with each other, and the plurality of stations are respectively a last putting station 100, a polishing station 200, a gluing station 300, a baking station 400, a sole putting station 500, a sole pressing station 600, a freezing station 700 and a last removing station 800; the last putting station 100 can put the upper on the shoe last; the polishing station 200 can increase the roughness of the matching place between the outer surface of the upper and the sole to facilitate gluing, the gluing station 300 can apply glue to the matching area between the upper and the sole, and the baking station 400 can dry the glue on the upper and the sole; the sole putting station 500 can stick the sole to the upper, the sole pressing station 600 can press the upper and the sole together, and the freezing station 700 can realize the shaping of the shoe and the upper after gluing and freezing. In the closed box, the flow of gas can achieve rapid condensation of glue, increase the cooling speed of glue and improve work efficiency. The flow of gas is achieved by the fan, blowing air from the upper end and out from the lower end. The shoes enter from one side of the box and are discharged from the other side. During the transmission process, the glue is quickly dried by blowing gas, achieving the effect of cooling and freezing, thereby improving efficiency. This structure is a common structure and can be achieved by the drying box mechanism commonly used in industry. Different temperature control can be achieved according to different shoe structures. No specific structural limitation is made in this application. Any structure that achieves cooling can achieve the cooling function of this application; the last removal station 800 can separate the shoe upper from the shoe last 102; the loading and unloading of each of the above stations can be completed by the cooperation of a six-axis robot, which is set through a program and does not require manual participation and operation, saving manpower and improving work efficiency.

[0024] It also includes a material transfer component, which is matched with the assembly line to realize the transfer and transmission of materials between adjacent workstations. The material transfer component can be an AGV navigation cart or a conveyor belt structure. It stays at each workstation for the corresponding workstation processing time. After the processing is completed, the shoes in the processing process are placed back on the material transfer component and transferred to the next workstation for the next process. A finished product inventory area can be set at the end of the material transfer component, and qualified products can be placed together to facilitate subsequent unified packaging and processing.

[0025] It also includes a vulcanization station 900, which is located between the polishing station 200 and the gluing station 300. It can use the high temperature during the vulcanization process to shape the shoe upper, effectively release the stress of the shoe upper, reduce the risk of deformation in subsequent processes, and improve the quality stability of the shoes.

[0026] Specifically, the vulcanization station 900 includes a fixed seat 910, a shell 920, a conveying component 930, a supporting component 940, and a circulating hot air component. The fixed seat 910 is arranged on one side of the material transfer component and can carry the entire structure of the vulcanization station 900 to ensure stable operation. The shell 920 is mounted on the fixed seat 910 to form a relatively closed cavity, isolating it from external interference and realizing the circulation of internal hot air, thereby realizing the vulcanization of shoes. The conveying component 930 is arranged on the fixed seat 910, and both ends of the conveying component 930 extend outside the shell 920, which can serve as the inlet and outlet of the shoes. It can be specifically set according to actual production needs. The supporting component 940 is arranged on the conveying component 930; the supporting component 940 can carry the shoes, so that the shoes are transported to the outlet along a preset path at the inlet of the shell 920, and the shoes on the supporting component 940 are heated by the circulating hot air component in the shell 920. The circulating hot air assembly, mounted on housing 920, generates a circulating hot air flow. This assembly may include an air pump, heating wire, and other components, which are conventional technology and will not be further described here. During operation, hot air circulates within housing 920, evenly enveloping the shoes on support assembly 940, achieving efficient heat transfer and completing the vulcanization and shaping of the shoes.

[0027] In some embodiments, the conveying assembly 930 includes a conveying frame 931, a first conveying motor 932, at least one first drive sprocket 933, a second conveying motor 934, at least one second drive sprocket (not shown in the figure), and a conveying chain 935. The conveying frame 931 is fixed on the fixed seat 910, and both ends of the conveying frame 931 extend outside the shell 920 to realize the feeding and discharging of the vulcanization station 900. The first conveying motor 932 is provided at one end of the conveying frame 931 and can be provided at the feeding end of the conveying frame 931. The first drive sprocket 93 3 is rotatably provided at one end of the conveying frame 931 and is connected to the output shaft of the first conveying motor 932. The second conveying motor 934 is provided at the other end of the conveying frame 931 and can be provided at the discharge end of the conveying frame 931. The second drive sprocket is rotatably provided at the other end of the conveying frame 931 and is connected to the output shaft of the second conveying motor 934. The structure of the second drive sprocket is the same as that of the first drive sprocket 933. The conveying chain 935 is transmission-installed between the first drive sprocket 933 and the second drive sprocket, and a supporting assembly 940 is provided on the conveying chain 935.

[0028] The first conveying motor 932 drives the first drive sprocket 933 to rotate, and the second conveying motor 934 drives the second drive sprocket to rotate, thereby driving the conveying chain 935 to move along a set trajectory in the shell 920, and then driving the supporting assembly 940 and the shoes on the supporting assembly 940 to move along a set trajectory in the shell 920, and under the action of the heat flow of the circulating hot air assembly, the vulcanization and shaping of the shoes are achieved.

[0029] In some embodiments, the conveying frame 931 includes a first conveying plate 9311, a second conveying plate 9312, and multiple connecting rollers 9313. The first conveying plate 9311 is fixedly connected to the fixed seat 910, the second conveying plate 9312 is arranged parallel to the first conveying plate 9311, and multiple connecting rollers 9313 are arranged at equal intervals between the first conveying plate 9311 and the second conveying plate 9312. The first conveying plate 9311, the second conveying plate 9312, and the multiple connecting rollers 9313 jointly realize the stable connection of the conveying frame 931 on the fixed seat 910, and the multiple connecting rollers 9313 are provided with a conveying chain 935 on the periphery of the multiple connecting rollers 9313. The conveying chain 935 can be supported by the multiple connecting rollers 9313, thereby guiding the conveying trajectory of the conveying chain 935 in the shell 920.

[0030] In some embodiments, the supporting assembly 940 includes a conveying ring groove 941, a plurality of supporting roller shafts 942, and a waist-shaped ring groove 943. The conveying ring groove 941 is provided on the first conveying plate 9311 near the end of the connecting roller 9313, and the second conveying plate 9312 is close to the end of the connecting roller 9313. The plurality of supporting roller shafts 942 are fixed on the conveying chain 935 at equal intervals, and the supporting roller shafts 942 can be slidably provided between the two conveying ring grooves 941. The plurality of supporting roller shafts 942 are provided with shoes to be vulcanized. The sliding path of the supporting roller shafts 942 can be limited by the two conveying ring grooves 941. In order to realize the moving trajectory of the shoes to be vulcanized in the shell 920, a waist-shaped annular groove 943 is provided in the middle of the supporting roller 942. The waist-shaped annular groove 943 can reduce the area of ​​the middle part of the supporting roller 942 and increase the gap between two adjacent supporting rollers 942, thereby increasing the channel for hot air flow between multiple supporting rollers 942 and reducing the influence of the supporting rollers 942 on the flow of hot air in the shell 920. At the same time, when supporting the shoes to be vulcanized, the contact area between the shoes and the supporting rollers 942 can be reduced, thereby increasing the contact area between the shoes and the hot air flow, thereby improving the vulcanization effect and vulcanization uniformity.

[0031] In some embodiments, the supporting assembly 940 also includes multiple sliding rods 944 and multiple fixed plates 945. The two ends of the sliding rod 944 can slide in the conveying ring groove 941 respectively, and the multiple sliding rods 944 are fixed on the conveying chain 935 at equal intervals. The multiple fixed plates 945 are symmetrically arranged on the side of the sliding rod 944 away from the conveying chain 935, and a supporting roller shaft 942 is provided between the two fixed plates 945 located on the same sliding rod 944. The conveying chain 935 provides power to drive the sliding rod 944 to slide in the conveying ring groove 941, thereby driving the supporting roller shaft 942 to move. The top of the fixed plate 945 is higher than the top of the supporting roller shaft 942, and a guardrail structure can be formed on both sides of the supporting roller shaft 942 to prevent the shoes from detaching from the supporting roller shaft 942 during the vulcanization process.

[0032] In some embodiments, the supporting assembly 940 also includes a rotating shaft, a gear ring 946, and a rotating gear 947. The rotating shaft can be rotatably arranged between the two fixed plates 945, and both ends of the rotating shaft pass through the fixed plates 945. A supporting roller shaft 942 is coaxially sleeved on the rotating shaft. The gear ring 946 is arranged at one end of the first conveying plate 9311 close to the connecting roller 9313 and the second conveying plate 9312 close to the connecting roller 9313, and a conveying ring groove 941 is provided in the gear ring 946. The rotating gear 947 is sleeved on the end of the rotating shaft and meshes with the gear ring 946.

[0033] When the conveying chain 935 drives the sliding rod 944 to move, the fixed plate 945 and the rotating gear 947 will move accordingly. Since the rotating gear 947 is engaged with the gear ring 946, the rotating gear 947 will rotate during the movement of the rotating gear 947, thereby driving the rotating shaft to rotate and the supporting roller shaft 942 to rotate. Then, during the movement of the shoe to be vulcanized, the shoe to be vulcanized will roll and rub against the supporting roller shaft 942, driving the relative movement of the shoe to be vulcanized on the multiple supporting roller shafts 942, and changing the contact position of the shoe to be vulcanized with the supporting roller shaft 942 in real time, further improving the uniformity of the contact between the shoe to be vulcanized and the hot air flow, and improving the vulcanization effect.

[0034] In some embodiments, the supporting assembly 940 also includes a paddle 948, which is disposed on the supporting roller 942 and in the waist-shaped annular groove 943, and protrudes from the supporting roller 942. When the supporting roller 942 rotates, it drives the paddle 948 to rotate, so that the paddle 948 is in intermittent contact with the shoe to be vulcanized. When the paddle 948 is in contact with the shoe to be vulcanized, it lifts the shoe to be vulcanized so that it is in a semi-suspended state, thereby increasing the contact area between the hot air flow and the shoe to be vulcanized and improving the vulcanization effect. At the same time, the rotating paddle 948 can fan the hot air at the bottom of the shoe to be vulcanized, increase the amount of hot air contacted by the shoe to be vulcanized, and improve the vulcanization efficiency.

[0035] In some embodiments, a transfer gear may be provided between the rotating shaft and the rotating gear 947. The transfer gear is sleeved on the end of the rotating shaft. The rotating gear 947 can be rotatably provided on the fixed plate 945. The rotating gear 947 is engaged with the transfer gear and the gear ring 946. Through the transfer gear, the rotating shaft and the conveying chain 935 can be rotated in opposite directions, so that the vulcanized shoes move forward and retreat a certain distance at the same time, thereby increasing the retention time of the shoes to be vulcanized and improving the vulcanization effect. At the same time, the turbulence effect of the hot air flow around the shoes to be vulcanized can be enhanced, thereby further improving the vulcanization effect.

[0036] In some embodiments, the first conveying plate 9311 is spirally ascending on the fixed seat 910, which allows the shoes to be vulcanized to spirally ascend in the shell 920, increasing the residence time. At the same time, it can improve the uniformity of the distribution of the circulating hot air flow in the shell 920, further improving the vulcanization effect.

[0037] In some embodiments, it also includes a rear hammer massage station 120 and an inspection station 110. The rear hammer massage station 120 is located between the last fitting station 100 and the polishing station 200. The rear hammer massage station 120 can increase the fitting strength between the heel of the upper and the last. The inspection station 110 is located between the sole pressing station 600 and the freezing station 700. The inspection station 110 can detect the fitting strength between the upper and the sole.

[0038] In some embodiments, the assembly line is arranged in a U-shape, a ring shape or an S-shape, which can be set according to the site layout, or a traditional linear assembly line structure can be used. This structure is not limited by a specific shape and can also be set to an irregular shape, as long as the space meets the layout of the material transfer components and the conversion between multiple workstations.

[0039] The specific working principle is as follows: Workers first fit the shoe upper onto the last at lasting station 100, giving it a preliminary shape. The material transfer assembly then transports the fitted upper to the back-hammering massage station 120, where massage improves the fit between the heel and the last. The upper then proceeds to the polishing station 200 for polishing, enhancing adhesion and preparing for subsequent gluing. The polished upper then enters the vulcanization station 900, where a circulating hot air assembly heats the shoe on the support assembly 940, finalizing its shape and improving its stability. The shaped upper is then transferred to the gluing station 300 via the material transfer assembly for evenly coating the upper with glue. The upper then enters the baking station 400, where the glue is dried to accelerate curing and enhance its viscosity. The sole and upper are then initially assembled at the sole-applying station 500, followed by the pressing station 600, where pressure is applied to securely fit the upper to the sole. The shoes that have been sole-pressed will undergo a fit strength test at the inspection station 110. If they pass the test, they will enter the freezing station 700 for freezing treatment to stabilize the shoe molding effect. Finally, the shoe last will be removed from the shoe at the last removal station 800, completing the entire shoemaking process. The shoes will then be transported to the packaging area through the material transfer assembly to complete the product packaging.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
