Description

Technical Field

[0001] This invention relates to the field of skin coloring technology, specifically to a skin coloring device for the production and processing of silicone dolls. Background Technology

[0002] The surface coloring device for silicone doll production is specifically designed for the processing of bionic silicone doll skin. It is an automated spraying equipment adapted to the fine processing of silicone bionic human skin. This device integrates plasma activation, multi-axis contour spraying, and constant temperature air drying into a single structure. It relies on visual positioning and a contour robotic arm to complete layered spraying. The core principle is to first activate the low-energy silicone surface through a plasma unit to improve the adhesion of the color paste. Then, a multi-axis robotic arm carries a low-pressure atomizing spray gun, which moves at a constant speed according to a preset human body curved surface trajectory, precisely controlling the paint output and spraying distance. Skin color, blush, and texture color pastes are layered and superimposed. The sealed chamber, combined with circulating hot air, allows for immediate surface drying, preventing color paste from dripping. The entire process is sealed to reduce paint evaporation and loss, making it suitable for large-scale standardized silicone doll skin coloring production.

[0003] However, existing automated spray painting equipment relies on airflow atomization spray guns to complete the pigment delivery and coloring operations. During the spraying process, the spray gun continuously sprays high-pressure airflow outward, which directly impacts the doll's body, causing the doll to experience slight vibrations. This small vibration is unlikely to cause obvious defects on a smooth surface, but it is prone to causing orange peel or thickness fluctuations in deep and delicate recessed areas such as eye sockets, lip creases, finger creases, and knuckle sockets. The internal space of the recesses is narrow, and the airflow injected by the spray gun cannot dissipate smoothly, easily forming turbulence within the cavity. Combined with the slight shaking of the workpiece itself, it is easy to cause insufficient local color coverage and inconsistent shades, ultimately forming a fine orange peel texture on the inner wall of the recesses. Additional manual touch-up is required to repair this, increasing processing steps and production costs.

[0004] To address the aforementioned issues, innovative design based on existing methods is urgently needed. Summary of the Invention

[0005] The purpose of this invention is to provide a surface color spraying device for the production and processing of silicone dolls, so as to solve the problem of color defects in the fine recessed areas mentioned in the background art. The technical solution of this invention provides a solution that is significantly different from the existing technology, which is too simplistic.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a skin color spraying device for the production and processing of silicone dolls, comprising a main body, a fixed clamp seat installed on a working platform inside the main body, a sliding clamp seat slidably installed on the top of the fixed clamp seat, a fixed plate provided inside the main body, buffer components provided inside the fixed clamp seat and the sliding clamp seat, a rotating seat installed inside the main body, a movable seat rotatably installed on the surface of the rotating seat, and a material leveling component provided inside the movable seat; The buffer assembly includes a first sliding rod fixed in a fixed fixture seat and a buffer seat fixed in a sliding fixture seat. A sliding piston is slidably mounted at the end of the first sliding rod. A guide groove is provided in the first sliding rod. A second sliding rod is slidably mounted in the first sliding rod. A sliding block is fixed at the bottom end of the second sliding rod. A guide block is fixed on the side wall of the sliding block. A rotating piston is mounted at the top end of the second sliding rod. It also includes an oil tank disposed on the surface of the fixed plate, and a piston rod is slidably installed inside the oil tank.

[0007] Preferably, the surface of the buffer seat is provided with a buffer spring, and the sliding piston and the rotating piston are located inside the buffer seat.

[0008] Preferably, the sliding piston and the rotating piston are rotatably connected, and both the sliding piston and the rotating piston have multiple through holes on their surfaces.

[0009] Preferably, the guide groove is spiral-shaped, and the guide block is located inside the guide groove.

[0010] Preferably, the buffer seat, the first sliding rod, and the oil tank are all filled with oil, and the first sliding rod and the oil in the oil tank are connected by a hose.

[0011] Preferably, the material leveling assembly includes a fixed block fixed in the movable seat, a drive shaft is slidably mounted in the fixed block, two drive discs are mounted on the surface of the drive shaft, and a rotating disc is rotatably mounted at the bottom end of the drive shaft; It also includes a rotating rod rotatably installed in a movable seat, with two movable sleeves symmetrically slidably installed at both ends of the rotating rod, a limit block fixed to the side wall of the movable sleeve, and a nozzle provided on the surface of the rotating rod; It also includes a drive shaft that is slidably mounted in a fixed block, and a drive disc is fixed to the surface of the drive shaft.

[0014] Preferably, the movable seat at the top of the drive shaft extends out of the surface, and the end of the drive shaft is slidably connected to the rotating seat.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through its main body, fixed plate, and buffer assembly, gradually consumes the vibration energy generated by the spray gun airflow impacting the workpiece in layers. This suppresses the high-frequency micro-vibration and irregular shaking problems between the sliding fixture seat and the doll parts from the source, improves the orange peel texture and uneven coating thickness during the spraying process, reduces rework and repair processes caused by workpiece vibration, and simultaneously adaptively adjusts the buffer damping force in real time according to the changes in the spraying distance between the nozzle and the workpiece. This simplifies the equipment operation process, enhances the equipment's versatility, and improves the processing yield and overall production efficiency of the silicone doll skin coloring process.

[0016] 2. This invention, through the setting of a rotating seat, a movable seat, and a material leveling component, stably drives the entire nozzle to reciprocate in small amplitudes, so that the pigment paint mist can be sprayed into the narrow recessed cavities such as eye sockets, finger gaps, and joint sockets at different incident angles during the spraying process. This covers the coloring blind spots that are difficult to reach by conventional direct spraying, such as the side walls of the recesses and the bottom of the cavities, avoiding processing defects such as incomplete coloring of the inner walls and uneven depth of coloring. It also reduces the need for subsequent manual touch-up spraying, shortens the overall processing time, improves the overall simulation effect and processing consistency of the silicone doll's skin coloring, and stabilizes the yield rate of mass production in the workshop.

[0019] Please see Figures 1-9 The present invention provides a technical solution: a skin color spraying device for silicone doll production and processing, comprising a main body 1, a fixed clamp seat 101 installed on the working platform inside the main body 1, a sliding clamp seat 102 slidably installed on the top of the fixed clamp seat 101, a fixed plate 103 provided inside the main body 1, buffer components provided inside the fixed clamp seat 101 and the sliding clamp seat 102, a rotating seat 5 installed inside the main body 1, a movable seat 6 rotatably installed on the surface of the rotating seat 5, and a material leveling component provided inside the movable seat 6; The buffer assembly includes a first sliding rod 201 fixed in the fixed clamp seat 101 and a buffer seat 2 fixed in the sliding clamp seat 102. A sliding piston 202 is slidably mounted at the end of the first sliding rod 201. A guide groove 204 is provided in the first sliding rod 201. A second sliding rod 3 is slidably mounted in the first sliding rod 201. A sliding block 301 is fixed at the bottom end of the second sliding rod 3. A guide block 303 is fixed on the side wall of the sliding block 301. A rotating piston 302 is mounted at the top end of the second sliding rod 3. It also includes an oil tank 4 disposed on the surface of the fixed plate 103, and a piston rod 401 is slidably installed inside the oil tank 4.

[0020] The buffer components gradually consume the vibration energy generated by the airflow from the spray gun impacting the workpiece, suppressing the high-frequency micro-vibration and irregular shaking of the sliding fixture seat 102 and the doll parts from the source, improving the orange peel texture, uneven coating thickness and other poor spraying defects during the spraying process, and reducing the rework and repair process caused by workpiece shaking.

[0021] In one embodiment of the present invention, a buffer spring is provided on the surface of the buffer seat 2, and the sliding piston 202 and the rotating piston 302 are located inside the buffer seat 2. During the silicone doll spraying operation, the vibration generated by the airflow impacting the workpiece is quickly transmitted to the sliding clamp seat 102. The buffer spring on the surface of the buffer seat 2 serves as a primary buffer structure, dissipating most of the vibration kinetic energy. The sliding piston 202 and the rotating piston 302 inside the buffer seat 2 form a secondary buffer by relying on the oil inside the buffer seat 2, thereby improving the stability of batch spraying production and the quality of finished products.

[0022] In one embodiment of the present invention, the sliding piston 202 is rotatably connected to the rotating piston 302. Both the sliding piston 202 and the rotating piston 302 have multiple through holes 203 on their surfaces. The sliding piston 202 can slide with the rotating piston 302 but does not rotate with it, so that the sliding piston 202 and the rotating piston 302 can rotate relative to each other, thereby changing the overlapping area of ​​the through holes 203 on the sliding piston 202 and the rotating piston 302, and thus changing the buffer damping resistance.

[0023] In one embodiment of the present invention, the guide groove 204 is designed in a spiral shape, and the guide block 303 is located in the guide groove 204. During the movement of the sliding block 301, it rotates under the guidance and drive of the guide groove 204 and the guide block 303, which drives the rotating piston 302 to rotate and change the overlapping area of ​​the through hole 203.

[0024] In one embodiment of the present invention, the buffer seat 2, the first sliding rod 201 and the oil tank 4 are all filled with oil, and the first sliding rod 201 and the oil in the oil tank 4 are connected by a hose.

[0025] As one embodiment of the present invention, the material leveling component includes a fixed block 601 fixed in the movable seat 6, a transmission shaft 7 slidably mounted in the fixed block 601, two transmission disks 701 mounted on the surface of the transmission shaft 7, and a rotating disk 702 rotatably mounted on the bottom end of the transmission shaft 7. It also includes a rotating rod 8 rotatably installed in the movable seat 6. Two movable sleeves 802 are symmetrically slidably installed at both ends of the rotating rod 8. Limit blocks 803 are fixed on the side walls of the movable sleeves 802. A nozzle 801 is provided on the surface of the rotating rod 8. It also includes a drive shaft 9 that is limited and slidably installed in a fixed block 601, and a drive disk 901 is fixed on the surface of the drive shaft 9.

[0026] The uniform coating component stably drives the nozzle 801 to reciprocate slightly, allowing the pigment mist to penetrate narrow recesses such as eye sockets, finger gaps, and knuckles at different incident angles during the spraying process. This covers color blind spots that are difficult to reach with conventional direct spraying, such as the side walls and bottom of the recesses, thus avoiding processing defects such as incomplete coloring on the inner walls and uneven color depth. In one embodiment of the present invention, the drive disk 901 is closely attached to the transmission disk 701, and the drive disk 901 is located in the gap between the two transmission disks 701. The drive disk 901 can directly push the transmission shaft 7 to slide through the transmission disk 701.

[0027] In one embodiment of the present invention, the limiting block 803 has a U-shaped cross section, and the rotating disk 702 is located in the U-shaped opening of the two limiting blocks 803. The limiting block 803 restricts the range of motion of the rotating disk 702 to prevent separation. The transmission shaft 7 slides to drive the rotating disk 702 to pull the limiting block 803, and the movable sleeve 802 drives the rotating rod 8 and the nozzle 801 to swing back and forth.

[0028] In one embodiment of the present invention, the movable seat 6 at the top of the drive shaft 9 extends out of the surface, and the end of the drive shaft 9 is slidably connected to the rotating seat 5. When the movable seat 6 rotates to adjust the spraying angle, the end of the drive shaft 9 slides along the contact surface of the rotating seat 5, triggering the material leveling component.

[0029] Working principle: When using the skin coloring device for silicone doll production and processing, the silicone doll part to be processed is first clamped in the special fixture set on the surface of the sliding fixture seat 102. The main body 1 is equipped with a drive motor. The motor output is linked to the truss drive rotating seat 5 to drive the movable seat 6 to approach the silicone doll part, ready to carry out the skin coloring work. Under normal vertical spraying conditions, the pigment is continuously and stably sprayed outward through the nozzle 801. The high-pressure airflow carries the pigment and impacts the silicone doll parts. The vibration generated by the airflow impact is transmitted from the doll parts to the clamp, and the vibration load is further transmitted to the sliding clamp seat 102. A buffer seat 2 is fixed inside the sliding clamp seat 102. A buffer spring is provided on the surface of the buffer seat 2, and a rotating piston 302 and a sliding piston 202 are slidably installed inside the buffer seat 2. The sliding piston 202 is limited and slidably installed at the top of the first sliding rod 201. The rotating piston 302 is fixed at the top of the second sliding rod 3 slidably installed on the first sliding rod 201, and the first sliding rod 201 is fixed inside the fixed clamp seat 101. When the vibration is transmitted to the buffer seat 2, the buffer spring is compressed first, absorbing most of the instantaneous airflow impact kinetic energy and achieving initial vibration reduction. During the process, the first sliding rod 201 drives the sliding piston 202 and the rotating piston 302 to move in the sealed oil chamber of the buffer seat 2. The oil in the buffer seat 2 is squeezed by the sliding piston 202 and the rotating piston 302 and can only flow to the other side through the small through holes 203 on the surface of the sliding piston 202 and the rotating piston 302. The oil passing through the rotating piston 302 generates viscous resistance, which suppresses the rapid rebound of the buffer spring and avoids the instantaneous rebound of the buffer spring from forming secondary vibration. After the buffer spring is compressed and stores energy, the elastic potential energy of the buffer spring is released, which drives the buffer seat 2 to move in the opposite direction to reset. The first sliding rod 201 then drives the sliding piston 202 and the rotating piston 302 to move in the opposite direction, squeezing the oil in the opposite direction and generating reverse resistance. This counteracts the rebound inertia of the buffer spring, prevents the sliding clamp seat 102 from bouncing up and down, consumes the vibration energy generated by the airflow impact in layers, suppresses the overall high-frequency micro-vibration and shaking of the sliding clamp seat 102 and the doll parts, and reduces spraying defects such as orange peel texture and uneven coating thickness. As the motor-driven truss inside the main body 1 drives the nozzle 801 to gradually move downwards and closer to the doll component, the force of the sprayed airflow gradually increases due to the reduction in the spraying distance, and the vibration intensity increases accordingly. The piston rod 401, which is slidably installed in the oil tank 4 on the surface of the fixed plate 103, is gradually squeezed by the truss and slides into the oil tank 4, squeezing the oil in the oil tank 4. The oil enters the first sliding rod 201 through the hose, pushing the sliding block 301 and the second sliding rod 3 to move outwards from the first sliding rod 201. At the same time, the guide block 303 fixed to the side wall of the sliding block 301 is located in the spiral-designed guide groove 204 opened inside the first sliding rod 201. As the sliding block 301 moves... The movement of 1, guided by the spiral guide groove 204, causes the sliding block 301 to gradually rotate, which in turn drives the rotating piston 302 to rotate synchronously through the second sliding rod 3. The sliding piston 202, which is connected to the rotating piston 302, is limited and slidably installed at the end of the first sliding rod 201. It only moves with the rotating piston 302 and does not rotate with the rotating piston 302. The rotating piston 302 and the sliding piston 202 rotate relative to each other. The through hole 203 on the surface of the rotating piston 302 and the guide block 303 are misaligned as they rotate, changing the size of the oil flow port. The oil damping resistance changes synchronously, thereby changing the buffering degree and realizing adaptive adjustment of the buffering and vibration reduction strength according to the spraying distance. When the internal drive mechanism of the main body 1 drives the movable seat 6 to rotate as a whole to adjust the spraying angle and spray color on the recessed area of ​​the doll, the fixed block 601 fixed in the movable seat 6 rotates synchronously with the movable seat 6. The end of the drive shaft 9, which is slidably installed in the fixed block 601, is slidably connected to the rotating seat 5. During the rotation of the movable seat 6, the drive shaft 9 is pulled by the rotating seat 5 and slides in the fixed block 601. The drive disk 901 fixed on the surface of the drive shaft 9 is located in the gap between the two transmission disks 701 fixed on the surface of the transmission shaft 7. When the drive disk 901 moves synchronously with the drive shaft 9, it pulls the transmission shaft 7 to slide in the fixed block 601 through the transmission disk 701. At the same time as the transmission shaft 7 slides, it pulls the rotating disk 702 rotatably connected to its bottom end. The transmission disc 701 is located at the U-shaped opening of the two limiting blocks 803, and the movable sleeve 802, which is fixedly connected to the limiting blocks 803, is slidably mounted on the surface of the rotating rod 8. When the rotating disc 702 is pulled, it changes its own rotational deflection. The pulling force generated by the eccentric deflection of the rotating disc 702 drives the rotating rod 8 to swing back and forth through the limiting blocks 803 and the movable sleeve 802, thereby driving the nozzle 801 to swing back and forth slightly, so that the pigment paint mist can be injected into the recessed cavity at different incident angles, covering the side walls and bottom blind areas, reducing the subsequent manual touch-up spraying process, and improving the overall simulation effect and processing consistency of the silicone doll's skin coloring.
