Detailed Implementation

[0035] The following are specific embodiments of this application, described in conjunction with the accompanying drawings, to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments. In the following description, specific details such as particular configurations and components are provided merely to aid in a comprehensive understanding of the embodiments of this application. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope of protection of this application. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0037] It should be noted that the screen printing process for the shoe upper can be achieved using automated screen printing equipment, which performs multiple printing passes on the shoe upper. During operation, the automated screen printing equipment uses a conveyor to transport the shoe upper to be printed, and the printing assembly performs screen printing on the shoe upper on the conveyor. Before printing, the printing assembly needs to position the shoe upper on the conveyor. Since the shoe upper requires multiple printing passes, higher positioning accuracy is required. The lifting conveyor assembly provided in this application facilitates efficient and precise positioning of the shoe upper by the positioning mechanism.

[0038] refer to Figures 1-3 The lifting conveyor line includes a frame 10, a conveying device 20, multiple transfer tooling plates 40, and a lifting drive device 30. The frame 10 is equipped with a printing positioning platform 11. The conveying device 20 can run along a set conveying direction and pass through the printing positioning platform 11. Here, the conveying device 20 can be configured as a belt mechanism or a chain mechanism.

[0039] The transfer tooling plate 40 is used to place the shoe upper to be printed; the transfer tooling plate 40 is placed on the conveying device 20 and can be driven by the conveying device 20 to move along the conveying direction; as the conveying device 20 operates, each transfer tooling plate 40 passes through the printing positioning platform 11 in sequence. Here, the transfer tooling plate 40 can be connected to the conveying device 20 to form a connection relationship, or no connection relationship can be set.

[0040] The lifting drive device 30 is used to drive the conveyor device 20 to move up and down; when the transfer tooling plate 40 moves above the printing positioning platform 11, the lifting drive device 30 drives the conveyor device 20 to move down so that the transfer tooling plate 40 falls onto the printing positioning platform 11. In an optional technical solution, the lifting drive device 30 can be installed between the conveyor device 20 and the frame 10, and can drive the conveyor device 20 to move up and down based on the frame 10. In an optional technical solution, the lifting drive device 30 can be installed on a fixed structure other than the frame 10, and can drive the conveyor device 20 to move up and down based on this fixed structure.

[0041] In this application, the conveying device 20 runs along a set conveying direction and passes through the printing positioning platform 11. As the conveying device 20 runs, each transfer tooling plate 40 passes through the printing positioning platform 11 in sequence. When the transfer tooling plate 40 moves above the printing positioning platform 11, the lifting drive device 30 drives the conveying device 20 to move down, so that the transfer tooling plate 40 falls onto the printing positioning platform 11 and separates from the conveying device 20, thereby facilitating efficient and accurate positioning of the shoe upper to be printed.

[0042] In one embodiment of this application, reference is made to Figures 3-5 The conveying device 20 includes a support frame 21, a first belt drive mechanism 22, and a second belt drive mechanism 23. The first belt drive mechanism 22 and the second belt drive mechanism 23 can be belt mechanisms, chain mechanisms, etc. In one embodiment of this application, both the first belt drive mechanism 22 and the second belt drive mechanism 23 use synchronous belts.

[0043] The first belt drive mechanism 22 and the second belt drive mechanism 23 are spaced apart and parallel to each other; the printing positioning platform 11 is arranged between the first belt drive mechanism 22 and the second belt drive mechanism 23. The first belt drive mechanism 22 and the second belt drive mechanism 23 are mounted on the support bracket 21; the lifting drive device 30 is connected to the support bracket 21 and can drive the first belt drive mechanism 22 and the second belt drive mechanism 23 to lift synchronously through the support bracket 21.

[0044] The transfer tooling plate 40 spans the first belt drive mechanism 22 and the second belt drive mechanism 23, and presses down on the first drive belt 221 of the first belt drive mechanism 22 and the second drive belt 231 of the second belt drive mechanism 23; the first belt drive mechanism 22 and the second belt drive mechanism 23 can operate synchronously to drive the transfer tooling plate 40 to move.

[0045] The transfer tooling plate 40 is placed on the first transmission belt 221 of the first belt drive mechanism 22 and the second transmission belt 231 of the second belt drive mechanism 23. Therefore, when the first belt drive mechanism 22 and the second belt drive mechanism 23 can run synchronously, the first transmission belt 221 and the second transmission belt 231 jointly drive the transfer tooling plate 40 to move forward.

[0046] In one embodiment of this application, the conveying device 20 further includes a drive shaft 24 and a drive source 25; the first belt drive mechanism 22 has a first drive pulley 222, and the second belt drive mechanism 23 has a second drive pulley 232; the first drive pulley 222 and the second drive pulley 232 are both mounted on the drive shaft 24; the drive source 25 is poweredly connected to the drive shaft 24 and can synchronously drive the first drive pulley 222 and the second drive pulley 232 to rotate through the drive shaft 24.

[0047] The power connection between the drive source 25 and the drive shaft 24 can be a direct connection or a connection via other intermediate mechanisms, requiring only that the drive source 25 and the drive shaft 24 have power transmission capability. When the drive source 25 drives the drive shaft 24 to rotate, the first drive pulley 222 and the second drive pulley 232 on the drive shaft 24 can rotate synchronously, thereby enabling the first transmission belt 221 and the second transmission belt 231 to operate synchronously. The drive source 25 can be configured as a motor, pneumatic motor, or other types of device. In a specific embodiment, the drive source 25 can be configured as a servo motor, which can precisely control the conveying speed and stroke of the first belt drive mechanism 22 and the second belt drive mechanism 23.

[0048] In one embodiment of this application, the lifting drive device 30 includes a lifting bracket 31 and a telescopic drive element 32; the lifting bracket 31 is connected to the conveying device 20; the telescopic drive element 32 is connected to the lifting bracket 31 to drive the lifting bracket 31 to move up and down. In this design, the lifting bracket 31 and the load-bearing bracket 21 of the conveying device 20 can be an integral structure, or they can be connected by various methods, such as welding or bolting. The lifting drive device 30 can use various types of drive devices, such as cylinders or electric cylinders.

[0049] In one embodiment of this application, the lifting conveyor assembly further includes a sensor; the sensor is capable of sensing that the transfer tooling plate 40 has reached a predetermined position above the printing positioning platform 11; the lifting drive device 30 is capable of being linked with the sensor to drive the conveyor device 20 to move downwards when the transfer tooling plate 40 reaches the predetermined position above the printing positioning platform 11, so that the transfer tooling plate 40 falls onto the printing positioning platform 11.

[0050] Specifically, when the sensor detects that any transfer tooling plate 40 has reached a predetermined position above the printing positioning platform 11, the lifting drive device 30 responds to the sensor output signal and drives the conveying device 20 to move downward, causing the transfer tooling plate 40 to fall onto the printing positioning platform 11. After the printing assembly 50 completes printing, the drive conveying device 20 pushes the transfer tooling plate 40 upward, causing the transfer tooling plate 40 to separate from the printing positioning platform 11. At this time, the conveying device 20 can drive the transfer tooling plate 40 to continue moving forward along the conveying direction.

[0051] In one embodiment of this application, reference is made to Figure 6 The conveying device 20 is provided with baffles 12 on both sides. The baffles 12 are used to block the transverse sliding of the transfer tooling plate 40 so as to guide the transfer tooling plate 40 to move along the conveying direction of the conveying device 20.

[0052] In one embodiment of this application, reference is made to Figure 7 The transfer tooling plate 40 includes a base plate 41 and a glass plate 42 disposed on the base plate 41. The glass plate 42 is used to place the shoe upper to be printed. The glass plate 42 has multiple mounting holes 421, and the base plate 41 has multiple supports 43. The positions of the supports 43 correspond one-to-one with the mounting holes 421. The supports 43 pass through the corresponding mounting holes 421 and are connected to the base plate 41, and are partially located above the glass plate 42. In this structure, the supports 23 are threaded connectors, which are assembled on the base plate 21 by threaded engagement. Furthermore, the base plate 41 has multiple notches 411, which can reduce weight.

[0053] This application embodiment also provides a screen printing device, which includes the above-mentioned lifting conveyor assembly and a printing assembly 50. The printing assembly 50 is used to screen print shoe uppers on the transfer tooling plate 40.

[0054] The lifting conveyor line includes a frame 10, a conveying device 20, multiple transfer tooling plates 40, and a lifting drive device 30. The frame 10 is equipped with a printing positioning platform 11. The conveying device 20 can run along a set conveying direction and pass through the printing positioning platform 11. The transfer tooling plates 40 are used to place the shoe uppers to be printed; the transfer tooling plates 40 are placed on the conveying device 20 and can be driven by the conveying device 20 to move along the conveying direction; as the conveying device 20 operates, each transfer tooling plate 40 passes through the printing positioning platform 11 sequentially. The lifting drive device 30 is used to drive the conveying device 20 to lift and lower; when a transfer tooling plate 40 moves above the printing positioning platform 11, the lifting drive device 30 drives the conveying device 20 to move downwards, causing the transfer tooling plate 40 to fall onto the printing positioning platform 11. In an optional technical solution, the lifting drive device 30 can be installed between the conveying device 20 and the frame 10, and can drive the conveying device 20 to lift and lower based on the frame 10.
