Description

Five-axis shoe sole printing equipment Technical Field

[0001] This invention relates to the field of plastic molding technology, and in particular to a five-axis shoe sole printing molding device. Background Technology

[0002] 3D printers often use FDM (Fused Deposition Modeling) to print shoe soles. This involves heating and melting the printing material through a nozzle module with a heating device, and then spraying the melted material along a specific path to form a printed model.

[0003] In shoe manufacturing, five-axis 3D printers have been widely used in industry. A five-axis 3D printer includes a frame, a feeding motion system, and a workpiece motion system. The feeding motion system has three degrees of freedom, which enables the molten material to have three-dimensional motion capabilities, allowing the molten material to approach the workpiece from any position. The workpiece motion system is used to carry the workpiece, and it has two rotational degrees of freedom, which allows the molten material to approach the workpiece from any angle. Existing technology uses multiple injection guns for injection when performing multi-color molding, but after switching, the injection gun may not inject material for a long time, which causes blockage of the injection port and limits the development of multi-color molding. Technical issues

[0004] To overcome the technical defects of the existing technology, the present invention provides a five-axis shoe sole printing and molding equipment to ensure smooth multi-color molding. Technical solutions

[0005] The technical solution adopted in this invention is:

Each adhesive system includes an adhesive device, an adhesive lifting device, an adhesive storage device, and an adhesive power device. The adhesive storage device is slidably mounted on the injection tube. The adhesive device is rotatably mounted on the adhesive storage device. The adhesive power device is mounted at the bottom of the adhesive device and drives the adhesive device to swing. The adhesive lifting device is mounted at the bottom of the adhesive device and pushes the adhesive device to rotate, thereby exposing the injection tube.

[0016] Both the material injection moving system and the workpiece motion system are mounted on the frame. Each injection tube is mounted on the material injection moving system, which drives each injection tube to move above the workpiece motion system. Each material adhesion system includes an adhesion device, an adhesion lifting device, an adhesion storage device, and an adhesion power device.

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] As shown in Figures 1-4, this embodiment provides a five-axis shoe sole printing and molding equipment, including a frame 1, an injection moving system 2, a workpiece motion system 3, several injection tubes 4, and several adhesive systems 5. The injection moving system 2 and the workpiece motion system 3 are both mounted on the frame 1. Each injection tube 4 is mounted on the injection moving system 2, which drives each injection tube 4 to move above the workpiece motion system 3. Each adhesive system 5 includes an adhesive device 51, an adhesive lifting device 52, an adhesive storage device, and an adhesive power device 53. The adhesive storage device is slidably mounted on the injection tube 4, injecting material when the injection tube 4 is empty. Pipe 4 maintains low-speed material injection to ensure smooth outlet flow and multi-color molding. The material storage device retracts in real time after the material storage device 51 carries away the material, ensuring the material storage device 51 remains effective. The material storage device 51 is rotatably mounted on the material storage device. The material storage device 53 is mounted at the bottom of the material storage device 51. The material storage device 53 drives the material storage device 51 to swing, carrying away the material flowing out of the injection pipe 4 at low speed. The material storage lifting device 52 is mounted at the bottom of the material storage device 51. The material storage lifting device 52 pushes the material storage device 51 to rotate, thereby exposing the injection pipe 4. The material storage device 51 slides along the bottom of the injection pipe 4.

[0029] Specifically, the injection moving system 2 includes an injection transverse moving device 21, an injection longitudinal moving device 22, and an injection lifting device 23. The injection longitudinal moving device 22 is mounted on the frame 1, the injection transverse moving device 21 is mounted on the output end of the injection longitudinal moving device 22, the injection lifting device 23 is mounted on the output end of the injection transverse moving device 21, and the injection tube 4 is mounted on the output end of the injection lifting device 23. The injection transverse moving device 21, the injection longitudinal moving device 22, and the injection lifting device 23 are all screw-slider structures, which will not be described in detail here. The injection transverse moving device 21, the injection longitudinal moving device 22, and the injection lifting device 23 drive the injection tube 4 to approach the workpiece from any position.

[0030] Specifically, the workpiece motion system 3 includes a first workpiece rotary motor 31 and a second workpiece rotary motor 32. The first workpiece rotary motor 31 is mounted on the frame 1, and the second workpiece rotary motor 32 is mounted on the output end of the first workpiece rotary motor 31. A workpiece support plate is mounted on the output end of the second workpiece rotary motor 32. The workpiece support plate is used to support the workpiece for forming. The rotation axis of the first workpiece rotary motor 31 and the rotation axis of the second workpiece rotary motor 32 are perpendicular to each other. The combined use of the first workpiece rotary motor 31 and the second workpiece rotary motor 32 drives the workpiece to approach the injection pipe 4 at any angle.

[0031] Specifically, the material-adhesive device 51 includes a material-adhesive rotating frame 511 and a material-adhesive rotating plate 512. The material-adhesive rotating frame 511 is rotatably mounted on the material-adhesive storage device. The cross-section of the material-adhesive rotating plate 512 is arc-shaped. The rotation of the material-adhesive rotating frame 511 causes the material-adhesive rotating plate 512 to sweep at the discharge position of the injection pipe 4, so that the material flowing out of the injection pipe 4 at low speed can adhere to the material-adhesive rotating plate 512.

[0032] Specifically, the bottom of the material-adhesive rotary plate 512 is provided with several heat dissipation plates 513 to quickly reduce the temperature of the material-adhesive rotary plate 512, so that the material flowing out of the injection pipe 4 can continuously adhere to the material-adhesive rotary plate 512.

[0033] Specifically, a balance column 514 is installed on the material-adhesive rotary frame 511. The balance column 514 is located on the side of the rotation axis of the material-adhesive rotary frame 511 away from the material-adhesive rotary plate 512. The balance column 514 balances the center of gravity of the material-adhesive rotary frame 511, which facilitates the rotation of the material-adhesive rotary frame 511. However, even with the presence of the balance column 514, the center of gravity of the material-adhesive device 51 is still closer to the material-adhesive rotary plate 512 than closer to the balance column 514.

[0034] Specifically, the material-adhesive power unit 53 includes a pneumatic motor and an eccentric block. The eccentric block is installed at the output end of the pneumatic motor. The pneumatic motor drives the eccentric block to vibrate, causing the material-adhesive rotary frame 511 to swing back and forth.

[0035] Specifically, the material lifting device 52 is an air pipe, and the air outlet of the air pipe points to the tangential direction of the material rotating plate 512. When the air pipe is ventilated, it blows the material rotating plate 512 to rotate, thereby exposing the injection pipe 4, which is convenient for printing.

[0036] Specifically, the material storage device includes a material return spring and a material sticking slider. The injection pipe 4 is provided with a sliding groove 41, and the material sticking slider is slidably installed on the sliding groove 41 of the injection pipe 4. The two ends of the return spring are respectively installed on the injection pipe 4 and the material sticking slider. After the material sticking rotating plate 512 becomes thick due to the material sticking, the material sticking slider overcomes the elastic force of the return spring and returns, thereby ensuring that the material sticking rotating plate 512 can continuously stick material. The function of the return spring is to keep the material sticking rotating plate 512 always in contact with the injection port of the injection pipe 4.

[0037] When the material-adhesive rotary plate 512 needs to be used for material adhesion, the air pipe stops blowing air. Under the action of gravity, the material-adhesive device 51 gradually rotates, causing the material-adhesive rotary plate 512 to gradually rotate downwards, thereby causing the outlet of the injection pipe 4 to point towards the material-adhesive rotary plate 512. Then, the material-adhesive power device 53 is turned on to realize the reciprocating swing of the material-adhesive rotary frame 511.

[0038] The foregoing has shown and described the basic principles and main features of the present invention, as well as its advantages. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope. All such changes and modifications fall within the scope of the present invention as claimed, which is defined by the appended claims and their equivalents.
