[0025] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0026] In the description of the present invention, it is necessary to understand that the orientations or positional relationships indicated by the terms "upper", "lower", "top", "bottom", "inside", "outside", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] See also Figure 1-4 As shown, a spraying device for filling between material layers comprises a T-shaped nozzle 1, a positioning adjustment mechanism 2, a sleeve 3, a triangular box 4, a soft conduit 5, a short tube 6, a cylinder 7, a feed conduit 8 and a motor 9, one end of the T-shaped nozzle 1 is connected to a port on one side of the triangular box 4 through the soft conduit 5, and an electric heating plate 110 is provided on one side of the T-shaped nozzle 1, and a positioning adjustment mechanism 2 is provided on the other side of the T-shaped nozzle 1;

[0028] The positioning adjustment mechanism 2 includes a block 210, an outer semi-ring gear plate 220, an inner semi-ring gear plate 230, a first gear 251 and a second gear 261. The first gear 251 is installed in the first circular groove 211 located on one side of the block 210, and the first gear 251 is meshed with the inner tooth surface of the outer semi-ring gear plate 220. The second gear 261 is installed in the second circular groove 213 located on the other side of the block 210, and the second gear 261 is meshed with the outer tooth surface of the inner semi-ring gear plate 230. One end of a transmission rod 910 is installed on the top of the block 210, and the other end of the transmission rod 910 is connected to the motor 9 located at one end of the sleeve 3.

[0029] The first arc hole 212 and the second arc hole 214 are respectively opened in different directions at the upper and lower ends of the block 210, and the inner top wall of the first arc hole 212 and the inner bottom wall of the second arc hole 214 are both provided with an arc guide block 240. The arc holes matching each semi-ring gear plate and combined with the arc guide block 240 ensure the stability of the lateral rotation operation of the semi-ring gear plate.

[0030] The first arc hole 212 is communicated with the middle part of the first circular groove 211 , and the second arc hole 214 is communicated with the middle part of the second circular groove 213 , so that the corresponding gear parts are located in the corresponding arc holes.

[0031] A first motor 250 is installed at the shaft end on one side of the first gear 251, and the first motor 250 is installed in the notch of the first circular groove 211; a second motor 260 is installed at the shaft end on one side of the second gear 261, and the second motor 260 is installed in the notch of the second circular groove 213. The operation of the motor at each position drives the corresponding gear to rotate, thereby driving the side rotation of the semi-ring gear plates in the corresponding meshing transmission connection.

[0032] The two ends of the outer semi-ring tooth plate 220 are rotatably connected to the corresponding parts on the other side of the T-shaped nozzle 1, and an arc guide groove 221 is provided on the outer surface of the outer semi-ring tooth plate 220. The two ends of the inner semi-ring tooth plate 230 are rotatably connected to the corresponding parts on the other side of the T-shaped nozzle 1, and the inner semi-ring tooth plate 230 and the outer semi-ring tooth plate 220 are vertically distributed. The inner semi-ring tooth plate 230 and the outer semi-ring tooth plate 220 are vertically distributed, and the two ends of the inner semi-ring tooth plate 230 and the two ends of the outer semi-ring tooth plate 220 are rotatably connected to the corresponding parts of the T-shaped nozzle 1, which helps to form a stable control implementation surface and avoids the shaking of the T-shaped nozzle 1 after it stops.

[0033] The transmission rod 910 is rotatably connected to the inside of the sleeve 3 through a bearing, and the inner side of the other end of the sleeve 3 is rotatably connected to the corresponding part of the triangular box 4 through a bearing. A short tube 6 is installed at the port on the other side of the feed of the triangular box 4, and the short tube 6 is rotatably connected to the inside of the barrel mouth of the cylinder 7 through a bearing. A feed conduit 8 is installed in the middle of the cylinder 7 to facilitate the use of the rotating transmission rod 910 to drive the connected T-shaped nozzle 1 and the triangular box 4 to be in a rotating state.

[0034] The sleeve 3 is partially located in the cylinder 7 , and the sleeve 3 and the cylinder 7 are in a coaxial position to prevent the feeding from hindering the operation of the transmission rod 910 located in the sleeve 3 .

[0035] Working principle: The overall structure is connected with the displacement mechanism part used for the traction movement of the print head on the 3D printing device, which can complete the synchronous movement of the T-shaped nozzle 1 and the print head, thereby combining Figure 1 As shown, when the external feeding device conveys the filling material through the feeding conduit 8, the middle part of one side of the T-shaped nozzle 1 is convex and located in the space between the printing material layers, so as to fill the space between the printing material layers. At the same time, the electric heating sheets 110 on both sides of the convex part of the middle part of one side of the T-shaped nozzle 1 are in contact with the surfaces on both sides of the printing material layers, so as to heat and melt the space, enhance the firmness of the connection between the filling material and the printing material, and make the filling surface flat and smooth, so as to solve the problem that the outer side of the printing material layer is uneven and the subsequent processing is difficult.

[0036] The motor 9 drives the connected transmission rod 910 to rotate the connected positioning adjustment mechanism 2, and the first motor 250 drives the first gear 251 to rotate, so that the meshing outer semi-ring gear plate 220 rotates sideways, achieving the effect of driving the connected T-shaped nozzle 1 to rotate sideways on one plane, and the second motor 260 drives the second gear 261 to rotate, so that the meshing inner semi-ring gear plate 230 rotates sideways, achieving the effect of driving the connected T-shaped nozzle 1 to rotate sideways on another plane. The inner semi-ring gear plate 230 and the outer semi-ring gear plate 220 are vertically distributed, and the two ends of the inner semi-ring gear plate 230 and the two ends of the outer semi-ring gear plate 220 are respectively rotatably connected to the corresponding parts of the T-shaped nozzle 1, which helps to form a more stable control implementation surface, avoids the shaking of the T-shaped nozzle 1 after it is stationary, and can meet the use and adjustment needs of the T-shaped nozzle 1 for filling in interlayer spaces of different depths and sizes.
