Description

Technical Field

[0001] This utility model belongs to the field of 3D printing technology, specifically relating to a multi-layer structure 3D printed shoe. Background Technology

[0002] 3D printing technology has demonstrated its unique advantages and application potential in multiple fields. Particularly in the footwear manufacturing industry, 3D printing technology, with its high precision, high efficiency, and customizability, has brought revolutionary changes to the traditional footwear industry. Against this backdrop, the research and application of multi-layered 3D-printed shoes have emerged, further meeting the market's demand for personalized, high-performance footwear products. This includes using 3D printing technology to print anti-slip patterns on the sole of the shoe plate, and printing the shoe body on the surface of the sole.

[0003] Currently, shoe soles require processing to form a complete shoe. However, for 3D printing, when printing the shoe plate, it is necessary to print anti-slip patterns on the bottom of the shoe plate and print the shoe body on the surface of the shoe plate. During the printing process, the shoe plate itself is fixed by clamping the upper and lower ends of the shoe plate, which can cause obstructions on the surface of the sole, thus affecting the printing operation. Furthermore, after one side of the shoe plate is printed, it still needs to be manually flipped over for printing, which is not conducive to the automatic operation of printing. Utility Model Content

[0004] The purpose of this invention is to provide a multi-layer structure 3D printed shoe to solve the problems of obstructions and flipping when fixing the sole in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-layer 3D printed shoe includes a printing table and a sole. A clamping assembly is installed on the printing table to clamp the heel end of the sole. An angle adjustment mechanism is installed at the bottom of the clamping assembly to change the axial angle of the clamping assembly. A support mechanism is slidably installed on the surface of the printing table to support the front end of the sole.

[0007] Furthermore, the clamping assembly includes a clamping platform, which is semi-elliptical in shape. Several positioning posts are detachably installed inside the clamping platform. Both ends of the positioning posts are threaded with sleeves. A support rod is installed inside the positioning post. A disc is fixed on the support rod. A spring is sleeved on the support rod. One end of the support rod extends out of the positioning post and faces into the clamping platform.

[0008] Furthermore, the clamping platform is equipped with electric push rods at both ends, and the output ends of the electric push rods are connected to anti-slip teeth. The anti-slip teeth can provide strong friction against the outer wall of the shoe sole, thereby fixing the position of the shoe sole. Combined with the thrust provided by the spring to push the support rod, the installation of the shoe sole is further stabilized.

[0009] Furthermore, one end of the support rod is a pointed cone. The pointed cone, when in contact with the side of the sole, causes deformation of the sole, thereby improving the fixation effect and increasing the pressure.

[0010] Furthermore, the angle adjustment mechanism includes a motor and a connecting plate. The connecting plate is installed on the bottom nut of the clamping table, and a rectangular frame is fixed on the surface of the connecting plate. A connecting shaft is inserted inside the rectangular frame. The motor is installed on the surface of the printing table, and the output end of the motor is connected to the connecting shaft.

[0011] In the above scheme, the motor starts and drives the connecting shaft to rotate. The rotation angle of the connecting shaft is controlled by the PLC controller, thereby changing the angle of the clamping component. When the angle of the clamping component changes, it also drives the sole to flip. After one side of the sole has been printed, the PLC controller controls the start motor to rotate, thereby flipping the sole over. The printer then continues to print the other side of the sole. In this way, the 3D printer can achieve multi-layer printing of the sole.

[0012] Furthermore, the support mechanism includes a slide plate, on the surface of which telescopic devices are symmetrically arranged. A support plate is fixed to the top of the telescopic devices. A bridging block is connected to the side of the slide plate. A limiting plate is installed on one side of the bridging block. A slider is located on the bottom side of the limiting plate. A stabilizing sleeve is symmetrically arranged at the bottom of the printing table. A sliding rod is installed on the stabilizing sleeve and is fitted inside the slider.

[0013] In the above scheme, the controller activates the telescopic mechanism to raise and lower the height of the support plate, so that the support plate supports the front end of the sole. The support height of the support plate is adjusted according to the thickness of the sole, or the position of the support plate is adjusted when flipping the sole after printing, so that the sole remains parallel to the printing table when the support plate supports the sole. The support position of the support plate is changed by the displacement of the slide plate, thus stabilizing the position of the sole and preventing wobbling during 3D printing.

[0014] Furthermore, a cylinder is installed at the bottom of the printing table, and the output end of the cylinder is fixedly connected to the limiting plate. The cylinder can automatically adjust the displacement distance of the limiting plate, eliminating the need for manual pushing of the limiting plate, simplifying the manual operation steps, and improving the automation of the operation.

[0015] The technical solution of this utility model has the following beneficial effects:

[0016] 1. The anti-slip teeth press against the outer wall of the sole, providing strong friction to fix the position of the sole. Combined with the thrust provided by the spring to push the support rod, the installation of the sole is further stabilized. The entire sole is held and stabilized by the clamping table in a flat position. The clamping table uses a side clamping method to ensure that there are no obstructions on the surface of the sole, which facilitates the printer to print on the sole surface.

[0017] 2. The PLC controller controls the rotation angle of the connecting shaft, thereby changing the angle of the clamping component. When the angle of the clamping component changes, it will also drive the sole to flip. After one side of the sole has been printed, the PLC controller controls the starter motor to rotate, thereby flipping the sole and continuing to print the other side of the sole through the printer. In this way, the 3D printer can achieve multi-layer printing of the sole. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] Example 1:

[0027] refer to Figure 1 A multi-layer structure 3D printed shoe includes a printing table 10 and a sole 11. A clamping assembly is installed on the printing table 10, which is used to clamp the end of the sole 11.

[0028] refer to Figures 1-3 The clamping assembly includes a clamping platform 12, which is semi-elliptical in shape. Several positioning posts 13 are detachably installed inside the clamping platform 12. Both ends of the positioning posts 13 are threaded with sleeve heads 14. A support rod 15 is installed inside the positioning posts 13. A disc 16 is fixed on the support rod 15. A spring 33 is sleeved on the support rod 15. One end of the support rod 15 extends out of the positioning posts 13 and faces into the clamping platform 12.

[0029] In the above scheme, the semi-elliptical clamping platform 12 can well conform to the periphery of the sole 11, so that the clamping platform 12 surrounds and wraps around the outer wall of the sole 11. With the use of positioning posts 13, the sole 11 is placed in the clamping platform 12 and pushed to one side. The periphery of the sole 11 will contact the support rod 15. The spring 33 is supported between the disc 16 and the sleeve 14. When the support rod 15 is squeezed by the periphery of the sole 11, the spring 33 will compress. The use of several positioning posts 13 can make multiple support rods 15 support the periphery of the sole 11. In this way, according to the contraction of each support rod 15, the sole 11 can be completely attached to the clamping platform 12. When the sole 11 is removed, the spring 33 will automatically provide a pushing force to reset the support rod 15. The detachable positioning column 13 is connected to the clamping table 12 by a threaded installation. The position of the positioning column 13 can be rotated and adjusted to change the support distance of the support rod 15; or the support distance of the support rod 15 can also be changed by replacing the spring 33 with a different stroke. This structure is easy to replace and disassemble.

[0030] Further reference Figure 2 and Figure 3The clamping platform 12 has electric push rods 18 at both ends, and the output ends of the electric push rods 18 are connected to anti-slip teeth 19. When the sole 11 is pushed to support the surface of the support rod 15, the electric push rods 18 on both sides are activated, which pushes the anti-slip teeth 19 to move, thereby pressing the anti-slip teeth 19 against the outer wall of the sole 11. The anti-slip teeth 19 can provide strong friction against the outer wall of the sole 11, thereby fixing the position of the sole 11. Combined with the pushing force provided by the spring 33 to push the support rod 15, the installation of the sole 11 is further stabilized. The entire sole 11 is clamped and stabilized by the clamping platform 12 in a flat manner. At the same time, the clamping method of the clamping platform 12 is a side clamping method, which ensures that there are no obstructions on the surface of the sole 11, which facilitates the printer to perform printing operations on the surface of the sole 11.

[0031] Furthermore, one end of the support rod 15 is a pointed cone 17. Combined with the synchronous clamping of the anti-slip teeth 19, the pointed cone 17 contacts the side of the sole 11, which can improve the stability and support effect. The pointed cone 17 contacts the side of the sole 11, which will cause the side of the sole 11 to deform, thereby improving the fixation effect and increasing the pressure.

[0032] refer to Figure 2 An angle adjustment mechanism is installed at the bottom of the clamping assembly, which is used to change the axis angle of the clamping assembly. The angle adjustment mechanism includes a motor 23 and a connecting plate 20. The bottom nut of the clamping table 12 is equipped with the connecting plate 20. A rectangular frame 21 is fixed on the surface of the connecting plate 20. A connecting shaft 22 is inserted inside the rectangular frame 21. The surface of the printing table 10 is equipped with a motor 23. The output end of the motor 23 is connected to the connecting shaft 22.

[0033] In the above scheme, a nut is installed on the side of the rectangular frame 21. The connecting shaft 22 inside the rectangular frame 21 is fixed by rotating and pressing the nut. The motor 23 starts and drives the connecting shaft 22 to rotate. The rotation angle of the connecting shaft 22 is controlled by the PLC controller, thereby changing the angle of the clamping component. When the angle of the clamping component changes, the sole 11 will also be flipped synchronously. After one side of the sole 11 has been printed, the PLC controller controls the start motor 23 to rotate, thereby flipping the sole 11 and continuing to print the other side of the sole 11 through the printer. In this way, the sole 11 can be printed in multiple layers by the 3D printer.

[0034] refer to Figure 4 and Figure 5A support mechanism is slidably mounted on the surface of the printing table 10, which is used to support the front end of the shoe sole 11. The support mechanism includes a slide plate 24, on the surface of the slide plate 24 are symmetrically provided with telescopic devices 25, a support plate 26 is fixed to the top of the telescopic device 25, a bridging block 27 is connected to the side of the slide plate 24, a limiting plate 28 is installed on one side of the bridging block 27, a slider 29 is provided on the bottom side of the limiting plate 28, and a stabilizing sleeve 30 is symmetrically provided at the bottom of the printing table 10. A sliding rod 32 is installed on the stabilizing sleeve 30 and is sleeved in the slider 29.

[0035] In the above scheme, the slide bar 32 is sleeved inside the slider 29 so that the limiting plate 28 can be stably moved by the slide bar 32. Since the slide plate 24 and the limiting plate 28 are connected by the bridging block 27, when the limiting plate 28 moves, it will drive the slide plate 24 to move synchronously. The telescopic device 25 is electrically connected to the controller. The controller starts the telescopic device 25 to raise and lower the height of the support plate 26 so that the support plate 26 supports the front end of the sole 11. The support height of the support plate 26 is adjusted according to the thickness of the sole 11 or the position of the support plate 26 is adjusted when flipping after printing, so that when the support plate 26 supports the sole 11, the sole 11 remains parallel to the printing table 10. The support position of the support plate 26 is changed by the displacement of the slide plate 24, so that the position of the sole 11 is stabilized and prevented from shaking during 3D printing. When the sole 11 needs to be adjusted by the angle adjustment mechanism, the slide plate 24 needs to be moved to the rear end of the printing table 10, and then the sole 11 is flipped by the angle adjustment mechanism.

[0036] Further reference Figure 4 A cylinder 31 is installed at the bottom of the printing table 10, and the output end of the cylinder 31 is fixedly connected to the limiting plate 28. The cylinder 31 can automatically adjust the displacement distance of the limiting plate 28, eliminating the need for manual pushing of the limiting plate 28, simplifying the manual operation steps and improving the automation of the operation.

[0037] Finally, by combining the electric push rod, motor 23, telescopic device 25, and cylinder 31 in the above scheme, and integrating them into the PLC control system, automatic control can be achieved through the PLC control system.

[0038] The specific implementation process of this embodiment is as follows:

[0039] Step 1: Place the sole 11 inside the clamping platform 12 and push it to one side. The area around the sole 11 will contact the support rod 15. When the support rod 15 is squeezed by the area around the sole 11, the spring 33 will compress. The use of several positioning pins 13 can make multiple support rods 15 support the area around the sole 11. In this way, according to the contraction of each support rod 15, the sole 11 can be completely attached to the clamping platform 12.

[0040] Step 2: Activate the electric push rods 18 on both sides, which push the anti-slip teeth 19 to move, so that the anti-slip teeth 19 are pressed against the outer wall of the sole 11. The anti-slip teeth 19 can provide strong friction on the outer wall of the sole 11, thereby fixing the position of the sole 11. The telescopic device 25 is activated by the controller to raise and lower the height of the support plate 26, so that the support plate 26 supports the front end of the sole 11. The support height of the support plate 26 is adjusted according to the thickness of the sole 11.

[0041] Step 3: Begin printing one side of the sole using a 3D printer (print the sole first, then the upper);

[0042] Step 4: After one side of the sole 11 has been printed, the cylinder 31 can automatically adjust the displacement distance of the limit plate 28 to move the slide plate 24 to the end of the printing table 10. Then, the PLC controller controls the start motor 23 to rotate, thereby flipping the sole 11 over and continuing to print the other side of the sole 11 through the printer.

[0043] Step 5: After the double-sided printing of the sole 11 is completed, activate the electric push rods 18 on both sides to disengage the anti-slip teeth 19 from the sides of the sole 11.
