[0017] Step 4: After spraying the transparent primer, the intermittent rotating table drives the shoes to rotate 60 degrees, so that the shoes are transferred from the primer spraying station to the primary drying station;

[0018] Step 5: The first linear drive member at the primary drying station drives the drying hood to move toward the side close to the intermittent rotating table, so that the drying hood covers the shoes, and then blows hot air to the uppers of the shoes through the hot air pipe to dry the transparent primer on the uppers of the shoes;

[0019] Step 6: After the transparent primer on the shoe upper is dry, the first linear drive member first drives the drying hood to move away from the intermittent rotating table, and then the intermittent rotating table drives the shoe to rotate 60 degrees, so that the shoe moves from the primary drying station to the filamentous glue spraying station;

[0020] Step 7: The silk glue spraying robot drives the glue spraying gun to move, and at the same time cooperates with the shoe rotating sleeve mechanism to drive the shoe to rotate, so as to spray the silk glue mixed with high viscosity ink on the shoe upper;

The intermittent rotating table 1 is provided with a plurality of shoe rotating sleeve mechanisms 2 corresponding to the workstations one by one. The shoe rotating sleeve mechanism 2 is used to sleeve the shoes and can drive the shoes to rotate. The plurality of workstations include a loading and unloading station 71, a primer spraying station 72, a primary drying station 73, a silk-like glue spraying station 74, a dot glue applying station 75 and a secondary drying station 76 arranged in sequence.

At the same time, the shoe rotating sleeve mechanism 2 is used to drive the shoes to rotate in the primer spraying station 72, the silk glue spraying station 74 and the dot glue applying station 75. In this way, the shoe uppers can be sprayed with transparent primer, dried once, sprayed with silk glue, applied Dot glue and secondary drying, and by adding high-viscosity ink to the glue, the upper of the shoe has a transparent primer layer, colored silk glue and colored dot glue, so as to achieve a three-dimensional glue coating and spray painting effect on the upper. The irregularly distributed dot glue resembles microscopic particles, such as quarks, and the irregularly distributed and irregular silk glue resembles the movement trajectory of microscopic particles. In this way, the upper of the shoe can have a pattern that simulates the movement effect of microscopic particles, effectively ensuring the overall aesthetics of the shoe and better meeting people's wearing needs. Moreover, since the high-viscosity ink is added to the glue, the color of the pattern on the upper that simulates the movement effect of microscopic particles is effectively ensured to last.

[0039] In addition, the shoes can be cleaned with a corresponding treatment agent before loading.

[0040] like Figure 1 As shown, the primer spraying station 72 is provided with a primer spraying manipulator 31, and a paint spraying gun 32 is installed on the end claw seat of the primer spraying manipulator 31.

The silk glue spraying station 74 is provided with There is a glue-spraying robot 41, and a glue gun 42 is installed on the end claw seat of the glue-spraying robot 41. The glue-spraying robot can use an intelligent robot already sold on the market, so its specific structure and principle are not described in detail here. The glue gun 42 supplies glue through the glue supply device in the existing technology, so that it is convenient to spray glue on the upper of the shoe and form a random, irregular, and irregular brushed pattern on the upper. In addition, high-viscosity ink can be added to the glue to make the brushed pattern have a corresponding color.

[0041] like Figure 1As shown, in addition, the primary drying station 73 and the secondary drying station 76 are both provided with a shoe upper drying mechanism 5.

The drying seat 51 is arranged on one side of the intermittent rotating platform 1, and the drying cover 52 is arranged on one side of the top of the drying seat 51. The first linear drive member 53 is installed on the drying seat 51 and is used to drive the drying cover 52 to move along the radial direction of the intermittent rotating platform 1. The drying seat 51 is provided with a first guide component 55 for guiding the movement of the drying cover 52, and at the same time can effectively ensure the stability and smoothness of the drying cover 52 when moving. The drying cover 52 is provided with a first linear drive member 53 to guide the intermittent rotating platform 1. A drying chamber 521 is open on one side of the table 1, and at least one hot air pipe 54 is installed on the inner bottom surface and the inner top surface of the drying chamber 521 on the drying hood 52. The hot air pipe 54 is provided with multiple hot air outlets along its length. Accordingly, the hot air pipe 54 is supplied with hot air by a hot air supply device in the prior art. When the shoe upper needs to be dried quickly, the drying hood 52 is driven by the first linear drive member 53 to move toward the side close to the intermittent rotating table 1, and the drying hood 52 covers the shoes. Then the hot air provided by the hot air supply device can be blown out through the hot air outlet on the hot air pipe 54, thereby achieving the effect of quickly drying the shoe upper.

The first guide rod is adapted to the first guide sleeve, and the first guide rod is sleeved in the first guide sleeve and the two are slidably matched. The drying hood 52 is provided with 2-3 hot air pipes 54 on the inner bottom surface and the inner top surface of the drying chamber 521, and the hot air pipe 54 is provided with 6-10 hot air outlets along its length.

[0044] like Figure 1 、 Figure 4 and Figure 5As shown, a glue dot applying mechanism 6 is provided at the glue dot applying station 75. Specifically, the glue dot applying mechanism 6 includes a fixed seat 61, a top cover 62, a glue dot block 63, an elastic sheet 64, a toggle drive assembly 65 and a swing lifting assembly 66.

A notch communicating with the top cavity is provided at the top of the top cover 62. The elastic sheet 64 and the toggle drive assembly 65 are both provided on the swing lifting assembly 66 and located in the top cavity. The toggle drive assembly 65 is used to toggle the elastic sheet 64 to bend and release the rebound. The swing lifting assembly 66 is provided on the top cover 62 and located at the notch and is used to drive the elastic sheet 64 and the toggle drive assembly 65 to swing left and right and lift synchronously. The glue dot block 63 is fixedly provided at the bottom of the elastic sheet 64. The bottom end of the glue dot block 63 The surface is provided with multiple glue outlets, and the glue dispensing block 63 is equipped with multiple glue inlet pipes 631 corresponding to and communicating with the glue outlets. The glue inlet pipes 631 are hoses. The glue dispensing block 63 can be supplied with glue by the glue supply device in the prior art, and glue is discharged from the glue outlet on the glue dispensing block 63. The elastic sheet 64 is toggled by the toggle drive component 65 to bend and release the rebound. When the elastic sheet 64 is released and rebounds, the glue at the glue outlet can be quickly thrown off and randomly dripped onto the shoe surface to form irregular glue dots. At the same time, the swing lifting component 66 can drive the elastic sheet 64 and the toggle drive component 65 to swing and lift synchronously left and right, and cooperate with the shoe rotating sleeve mechanism 2 to drive the shoe to rotate, so that the glue dots dripping on the shoe surface can be more randomly and irregularly distributed, so that the shoe surface of each shoe has a single unique pattern imitating the motion effect of microscopic particles.

[0046] like Figure 5As shown, specifically, the swing lifting assembly 66 includes a swing plate 661, a lifting plate 662, a swing motor 663 and a second linear drive member 664. The swing plate 661 is rotatably mounted on the top cover 62. The swing motor 663 is fixedly mounted on the upper end of the top cover 62. The swing motor 663 can drive the swing plate 661 to swing left and right through an eccentric connecting rod assembly 665. The lifting plate 662 is located directly below the swing plate 661. The second linear drive member 664 is installed on the swing plate 661 and is used to drive the lifting plate 662 to move up and down. The swing plate 661 is provided with a device for moving the lifting plate 662 The second guide component 666 plays a guiding role in the lifting and lowering, and at the same time effectively ensures the stability and smoothness of the lifting plate 662 when it is lifted and lowered. The elastic sheet 64 and the toggle drive component 65 are both arranged at the lower end of the lifting plate 662. As a result, when the swing motor 663 drives the swing plate 661 to swing left and right, the lifting plate 662 can be swung left and right together, that is, the elastic sheet 64 and the toggle drive component 65 can be swung left and right synchronously. When the second linear drive member 664 drives the lifting plate 662 to lift and lower, the elastic sheet 64 and the toggle drive component 65 can be lifted and lowered synchronously.

[0047] Preferably, the second linear drive member 664 is a second hydraulic cylinder, a second air cylinder or a second electric push rod, the second guide assembly 666 is two and symmetrically arranged on both sides of the second linear drive member 664, the second guide assembly 666 includes a second guide rod and a second guide sleeve, the second guide rod is fixed on the lifting plate 662, the second guide sleeve is fixedly installed on the swing plate 661, the second guide rod is adapted to the second guide sleeve, the second guide rod is sleeved in the second guide sleeve and the two are slidably matched, the eccentric connecting rod Component 665 includes a swing rod, a connecting rod and a rotating plate. The rotating plate is fixedly mounted on the motor shaft of the swing motor 663. An eccentric shaft is fixedly provided at an eccentric position on the rotating plate. One end of the connecting rod is hinged to the eccentric shaft, and the other end of the connecting rod is hinged to one end of the swing rod. The other end of the swing rod is fixed on the fixed axis of the swing plate 661. Therefore, when the swing motor 663 drives the rotating plate to rotate, the linkage of the connecting rod facilitates driving the swing plate 661 to swing back and forth left and right.

[0048] Preferably, the swing motor 663 can be a reduction motor.

[0049] like Figure 5As shown, specifically, the toggle drive assembly 65 includes a toggle motor 651, a toggle shaft 652 and a toggle rod 653. The toggle motor 651 is fixedly mounted on a motor seat, and the motor seat is fixedly mounted on the lower end of the lifting plate 662. The toggle shaft 652 is fixedly mounted on the motor shaft of the toggle motor 651. The lower end of the toggle shaft 652 extends downward to the bottom of the elastic sheet 64. One end of the toggle rod 653 is fixedly mounted on the lower end of the toggle shaft 652. The other end of the toggle rod 653 is provided with a roller 654 that can roll against the elastic sheet 64. The lower end of the lifting plate 662 is also fixed with a limit plate 655 for limiting the rebound and reset of the elastic sheet 64.

During the rotation of the toggle rod 653, the roller 654 on one end of the toggle rod 653 can abut against the elastic sheet 64 and push the elastic sheet 64 to bend to one side. When the toggle rod 653 rotates and the roller 654 no longer abuts against the elastic sheet 64, the elastic sheet 64 can quickly rebound and reset to the other side under the action of its own elastic force, so as to quickly throw off the glue flowing out of the glue outlet on the glue dispensing block 63 and randomly drip onto the shoe surface to form glue dots.

[0050] Preferably, the toggle motor 651 can be a reduction motor, and the elastic sheet 64 can be made of an elastic steel sheet.

[0051] like Figure 4 As shown, in addition, a liftable bottom cover 67 is provided under the top cover 62, and a bottom cavity open upward is provided in the bottom cover 67. The bottom cover 67 is connected to the fixed seat 61 for sliding up and down through a sliding component 68. The fixed seat 61 is provided with a third linear drive member 69 for driving the bottom cover 67 to be lifted and lowered. When the shoes rotate to the bottom of the top cover 62 along with the intermittent turntable, the third linear drive member 69 can drive the bottom cover 67 to rise, thereby covering the shoes together with the top cover 62. In this way, when the point glue applying mechanism 6 applies point glue to the shoe upper, it can prevent the glue from falling directly onto the ground, effectively ensuring the cleanliness of the working environment.

[0052] Preferably, the third linear drive member 69 can be a third hydraulic cylinder, a third air cylinder or a third electric push rod, and the sliding assembly 68 is two and symmetrically arranged on the left and right sides of the third linear drive member 69.
