Specific embodiments

[0018] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments: Embodiment 1

[0019] Please refer to Figures 1-10 , a wax spraying device for automobile interior parts, including a support frame 1, a wax liquid tank 13 is installed on the support frame 1, a delivery pump is connected and installed on the wax liquid tank 13, a hollow rotating shaft 19 is rotatably installed on the support frame 1, a turntable 2 is fixed at the top of the hollow rotating shaft 19, and is characterized in that a plurality of radial grooves 35 are uniformly formed on the turntable 2, a clamping assembly is installed in each radial groove 35, a wood veneer 3 is clamped on the clamping assembly, a servo motor 14 is installed on the support frame 1, a step driving assembly is drivingly connected to the servo motor 14, and the step driving assembly is used to drive the turntable 2 to rotate step by step. A translation frame 8 is linearly and reciprocally slidably installed on the support frame 1 and is arranged opposite to the wood veneer 3. Two symmetrically arranged fixed side plates 20 are fixed on the translation frame 8. A wax spraying disk 23 is slidably installed on each fixed side plate 20 through a positioning assembly. A brush plate 25 is fixed on the wax spraying disk 23. A protective cover 12 is installed on the translation frame 8 above the wax spraying disk 23. A diversion pipe 22 is installed on the wax spraying disk 23. A bellows 11 is installed on the diversion pipe 22. The bellows 11 is connected to the outlet end of the delivery pump. A central pipe 36 is disposed through the hollow rotating shaft 19, and a return pipe 15 is connected and installed between the central pipe 36 and the wax liquid tank 13.

[0020] When the device is in use, the wood veneers 3 of multiple automobile interior parts are installed on the turntable 2 and clamped and fixed by the provided clamping assembly. The wax liquid in the wax liquid tank 13 is pumped by the delivery pump, and the wax liquid enters the wax spraying disk 23 along the bellows 11 and the diversion pipe 22, and the wood veneers 3 are subjected to surface wax spraying treatment through the wax spraying disk 23.

[0021] Specifically, the clamping assembly includes a push post 42 slidably mounted on the turntable 2, a clamping plate 4 for clamping the wood panel 3 is fixed on the push post 42, and a spring ring 41 is fixed between the clamping plate 4 and the turntable 2. The wood panel 3 is clamped between the two clamping plates 4, and the wood panel 3 is clamped and fixed by the elastic thrust of the spring ring 41.

[0022] The stepper drive assembly of the device includes an incomplete gear 17 fixed coaxially with the output shaft of the servo motor 14, and a driven gear 16 is fixedly sleeved on the hollow shaft 19, and the hollow shaft 19 intermittently meshes with the driven gear 16. The stepper drive assembly also includes a positioning plate 21 fixed on the support frame 1, and the hollow shaft 19 is rotatably mounted on the positioning plate 21. The positioning plate 21 is evenly provided with a plurality of arc grooves 37 in an annular direction, and a plurality of guide columns 39 are slidably mounted on the bottom of the turntable 2. An arc-shaped protrusion 38 is fixed on the bottom of the guide column 39, and the arc-shaped protrusion 38 is abutted and adapted with the arc groove 37. A push spring 40 is fixedly connected between the guide column 39 and the turntable 2.

[0023] Through the above configuration, the servo motor 14 can drive the incomplete gear 17 to rotate, and the incomplete gear 17 intermittently meshes with the driven gear 16 during the rotation process. At this time, the driven gear 16 drives the hollow shaft 19 to rotate, and the hollow shaft 19 drives the turntable 2 to rotate. The wood veneer 3 on the turntable 2 realizes step-by-step rotation, which is convenient for rotating the wood veneer 3 at different positions to correspond linearly with the translation frame 8, ensuring that multiple wood veneers 3 are waxed one by one. The arc-shaped protrusion 38 can be abutted against the arc groove 37 under the elastic push of the push spring 40, ensuring that the turntable 2 can be positioned in time after each rotation, ensuring the stability of the subsequent wax spraying process of the wood veneer 3.

[0024] In addition, an extension column 46 is fixed on the support frame 1, and the translation frame 8 is slidably sleeved on the extension column 46. A turntable 24 is rotatably installed on the support frame 1, and a transmission rod 34 is eccentrically hinged on the turntable 24. The end of the transmission rod 34 away from the turntable 24 is hinged to the translation frame 8, and the turntable 24 is connected to the output shaft of the servo motor 14 through a pulley mechanism 18.

[0025] While the servo motor 14 drives the incomplete gear 17 to rotate, the output shaft of the servo motor 14 drives the turntable 24 to rotate via the pulley mechanism 18, and the turntable 24 drives the translation frame 8 to reciprocate relative to the support frame 1 via the transmission rod 34. At this time, the wax spraying plate 23 moves linearly and is located on both sides of the wood veneer 3, thereby realizing the wax spraying treatment of the wood veneer 3. The turntable 2 rotates step by step once, and the wax spraying plate 23 reciprocates linearly once, thereby realizing the automatic wax spraying operation of the wood veneer 3, which greatly improves the wax spraying processing efficiency of the wood veneer 3. Example 2

[0026] See alsoFigures 1-10 Based on Embodiment 1, in addition, the positioning assembly of this device includes a positioning column 27 fixed to the wax spraying disc 23. The fixed side plate 20 is slidably sleeved on the positioning column 27. Two V-shaped grooves 31 are formed on the positioning column 27. A fixed frame 28 is fixed on the fixed side plate 20. A column 29 is slidably installed on the fixed frame 28. A connecting plate 33 is fixed to the bottom of the column 29. A triangular block 32 adapted to be inserted into the V-shaped groove 31 is fixed to the bottom of the connecting plate 33. A connecting spring 30 is fixed between the fixed frame 28 and the connecting plate 33.

[0027] Among them, a number of pairs of uniformly distributed pushing columns I6 are fixed on the turntable 2. A wedge block I7 linearly corresponding to the pushing column I6 is fixed on the wax spraying disc 23. A pushing column II9 is fixed on the support frame 1. A wedge block II10 linearly corresponding to the pushing column II9 is fixed at one end of the wax spraying disc 23 away from the pushing column I6.

[0028] Through the above settings, during the process of the translation frame 8 moving towards the turntable 2, the wedge block I7 is pushed by the pushing column I6, so that the wax spraying disc 23 moves towards the wood veneer 3 under the guiding action of the positioning column 27, making the brush plate 25 contact the surface of the wood veneer 3. Subsequently, when the translation frame 8 moves away from the turntable 2, the brush plate 25 scrapes the wax liquid sprayed on the wood veneer 3, ensuring that the wax liquid is evenly distributed on the surface of the wood veneer 3, greatly improving the wax spraying effect. When the wedge block II10 is pushed by the pushing column II9, the wedge block II10 drives the wax spraying disc 23 to reset. By alternately inserting and matching the set triangular block 32 with the two V-shaped grooves 31, the positioning effect after the position movement of the wax spraying disc 23 is switched is realized, and the wax liquid on the wood veneer 3 is scraped in one direction, ensuring the uniform distribution of the wax liquid on the wood veneer 3.

[0029] In addition, a number of lateral holes 44 are formed on the side wall of the central pipe 36. A return port 45 is formed on the turntable 2 and is located in the radial groove 35. An extension frame 5 is installed at the upper end of the central pipe 36. A filter cylinder 26 extending into the central pipe 36 is fixed to the bottom of the extension frame 5. A filter screen plate 43 is embedded and fixed at the bottom of the filter cylinder 26.

[0030] The excess wax liquid sprayed on the wood veneer 3 can gather in the radial groove 35, enter the central pipe 36 along the return port 45 and the lateral holes 44, and finally flow back to the wax liquid tank 13 along the return pipe 15 for recycling. The filter screen plate 43 provided in the filter cylinder 26 plays an effective filtering effect on the wax liquid, ensuring the wax spraying quality of the wood veneer 3.

[0031] In summary, in the present invention, the wax spraying disc 23 is provided to perform wax spraying treatment on the wood veneer 3. During the wax spraying process, the stepping drive assembly can drive the turntable 2 to rotate step by step, so that multiple wood veneers 3 can automatically switch positions. At the same time, the translation frame 8 can drive the wax spraying disc 23 to perform linear reciprocating motion, realizing automatic and individual wax spraying on the multiple wood veneers 3 installed on the turntable 2, greatly improving the degree of automation and significantly enhancing the wax spraying treatment efficiency of the wood veneer 3. During the linear reciprocating motion of the translation frame 8 provided in the present invention, after the wedge block I 7 abuts against the pushing column I 6, the two wax spraying discs 23 can be close to the wood veneer 3, and the brush plate 25 can contact the wood veneer 3, so that when the wax spraying disc 23 moves away from the turntable 2, the brush plate 25 can evenly brush the wax liquid sprayed on the wood veneer 3. After the wedge block II 10 abuts against the pushing column II 9, the brush plate 25 can reset with the wax spraying disc 23, thereby realizing the one-way brushing function of the brush plate 25 on the wood veneer 3, ensuring that the wax liquid can evenly adhere to the surface of the wood veneer 3 and greatly improving the wax spraying effect of the wood veneer 3.
