Description

Technical Field

[0001] This utility model relates to a spraying equipment for hot-drill production, and in particular to a hot-drill protective film spraying machine with adjustable spraying angle. Background Technology

[0002] During the processing of crystal rhinestones, a protective film is sprayed onto the surface to prevent the color layer from being scratched off. Currently, the common method for spraying this protective film is to manually place the rhinestones on a spraying device. However, since rhinestones have multiple facets with different angles, to ensure even coating, the process requires multiple stops and adjustments to the rhinestones' angles, resulting in low overall efficiency. Furthermore, due to these frequent stops and adjustments, the protective film may be too thick in some areas or scratched off in others, leading to a poor overall coating effect. Therefore, the current method of applying protective film to crystal rhinestones suffers from both poor coating quality and low efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable spraying angle hot-dip rhinestone protective film spraying machine. This invention not only ensures the spraying effect but also has the advantage of high work efficiency.

[0004] The technical solution of this utility model: A spraying angle adjustable hot-dip rhinestone protective film spraying machine includes a base, on which a hemispherical spraying frame is provided; a guide rail is provided on the inner top surface of the spraying frame, and an "L"-shaped movable seat is slidably mounted on the guide rail; a spraying pipe is provided on the bottom surface of the movable seat, and a drive motor is provided on the top surface of the movable seat; multiple evenly distributed support members are provided on one side of the guide rail, and an arc-shaped guide rack is provided between the ends of all the support members; a guide gear is meshed on the guide rack, and the guide gear is connected to the drive motor; a material transfer port is provided on the side of the spraying frame, and a protective door is rotatably mounted on the material transfer port; two symmetrically distributed fixed supports are provided on the top surface of the base corresponding to the position directly below the guide rack. The system consists of two fixed slide rails with a fixed base for holding hot rhinestones slidably mounted between them. When the drive motor starts, it drives the guide gear to rotate. During rotation, the guide gear meshes with the guide rack, causing the drive motor and the moving base to slide along the guide rails. The shape of the guide rails, combined with the spray nozzle mounted on the bottom of the moving base, allows for automatic multi-directional spraying of the hot rhinestones on the fixed base. This ensures effective spraying without requiring manual adjustment of the rhinestone angle, improving work efficiency. When the spraying angle needs adjustment, simply controlling the start time of the drive motor adjusts the spraying angle of the spray nozzle, enhancing flexibility and simplifying the overall structure.

[0005] In the aforementioned adjustable-angle hot-dip rhinestone protective film spraying machine, an adjusting groove is provided on the top surface of the spraying frame on the side away from the guide rail from the guide rack, and an angle scale line is provided on one side of the adjusting groove. Two first limiting members are slidably installed on the adjusting groove, and the bottom end of each first limiting member is slidably installed on the guide rail. The top end of the first limiting member is provided with a triangular indicator that cooperates with the angle scale line. By using the indicator and the angle scale line on one side of the adjusting groove to cooperate with each other, the user can easily observe the limiting position of the spraying angle, thereby further facilitating the use. Moreover, the setting of the first limiting member can limit the left and right movement of the moving seat on the guide rail, avoiding the phenomenon of over-movement and ensuring the stability of use.

[0006] In the aforementioned adjustable spray angle hot-dip rhinestone protective film spraying machine, two first limiting members are respectively arranged on both sides of the moving base; a first piezoelectric sensor is arranged on the side of each first limiting member near the other first limiting member; a controller is electrically connected to the first piezoelectric sensor, and the controller is electrically connected to the drive motor; by using the controller and the first piezoelectric sensor in cooperation, the drive motor can be stopped in time when the moving base contacts the first limiting member, thereby ensuring the stability of the operation.

[0007] In the aforementioned adjustable spray angle hot-drill protective film spraying machine, limit stops are provided on both sides of the guide rack; the top surface of the limit stop is located above the top surface of the guide rack, and the top surface of the limit stop is located below the central shaft of the guide gear; by using the limit stops to block the movement at both ends of the guide gear, the phenomenon of the guide gear disengaging from the guide rack is avoided, further ensuring the stability of the operation.

[0008] In the aforementioned adjustable spray angle hot-drill protective film spraying machine, a second limiting member is provided at the end of the fixed slide rail away from the material transfer port, and a second piezoelectric sensor is installed on the side of the second limiting member facing the material transfer port; the second piezoelectric sensor is electrically connected to the controller; the movement of the fixed seat can be limited and fixed by the second limiting member, thereby ensuring that the position of the hot-drill material is consistent each time, thus ensuring the spraying effect.

[0009] In the aforementioned adjustable spray angle hot-dip rhinestone protective film spraying machine, a transparent observation window is provided on the protective door; the transparent observation window facilitates the user's observation of the internal spraying work, making it convenient to use.

[0010] Compared with existing technologies, this utility model improves the existing spraying device for hot-fix rhinestone processing. It features an arc-shaped guide rail and guide rack on the spraying frame, with a guide gear meshing on the guide rack. A drive motor, slidably mounted on the guide rail, is connected to the guide gear. When the drive motor starts, it drives the guide gear to rotate, which in turn meshes with the guide rack, causing the drive motor and the moving base to slide along the guide rail. Combined with the shape of the guide rail, the spraying pipe mounted on the bottom of the moving base can automatically spray the hot-fix rhinestones mounted on the fixed base from multiple directions. The coating process ensures a good coating effect without requiring manual adjustment of the hot-fix rhinestone angle, thus improving work efficiency. Furthermore, the use of guide gears and racks for transmission allows for easy adjustment of the spray angle simply by controlling the start time of the drive motor, enhancing flexibility and simplifying the overall structure. A protective door at the material transfer port effectively prevents spray liquid from splashing out during coating, ensuring a comfortable user experience.

[0011] Furthermore, this utility model also incorporates an adjustable waist groove and a limiting component. An indicator is provided on the first line, which, in conjunction with the angle scale line on one side of the adjustable waist groove, allows the user to easily observe the spraying angle limit position, thus further facilitating use. Moreover, the first limiting component can limit the lateral movement of the moving seat on the guide rail, preventing over-movement and ensuring stability during use. A first piezoelectric sensor is provided on the first limiting component, electrically connected to a controller. The controller and the first piezoelectric sensor work together to ensure proper contact between the moving seat and the first limiting component. The timely control of the drive motor ensures operational stability. Limit stops on both sides of the guide rack prevent disengagement, further enhancing stability. A second limiter on the fixed slide rail restricts movement, ensuring consistent rhinestone placement and optimal coating. A transparent observation window on the protective door allows for easy monitoring of the coating process. Therefore, this invention not only guarantees coating quality but also offers advantages such as high efficiency, flexibility, simple structure, high user comfort, ease of use, and high operational stability.

[0019] An adjustment groove 14 is provided on the top surface of the sprayed outer frame 2 on the side of the guide slide rail 3 away from the guide rack 8. An angle scale line is provided on one side of the adjustment groove 14. Two first limiting members 15 are slidably installed on the adjustment groove 14. The bottom end of each first limiting member 15 is slidably installed on the guide slide rail 3. The top end of the first limiting member 15 is provided with a triangular indicator 16 that matches the angle scale line. The two first limiting members 15 are respectively provided on both sides of the movable seat 4. A first piezoelectric sensor 17 is provided on the side of each first limiting member 15 near the other first limiting member 15. The first piezoelectric sensor 17 is electrically connected to a controller 18, which is electrically connected to the drive motor 6. Limiting stops are provided on both sides of the guide rack 8. The top surface of the limiting stop is above the top surface of the guide rack 8 and below the central shaft of the guide gear 9. A second limiting stop 19 is provided at the end of the fixed slide rail 12 away from the material transfer port 10. A second piezoelectric sensor 20 is installed on the side of the second limiting stop 19 facing the material transfer port 10. The second piezoelectric sensor 20 is electrically connected to the controller 18. A transparent observation window is provided on the protective door 11.

[0020] Working principle: When performing the protective film spraying work, firstly connect the entire device to an external safe mains power supply, so that the controller 18, the first piezoelectric sensor 17, and the second piezoelectric sensor 20 are powered on and started (the controller 18 used in this utility model can be a programmable controller of model FX2C-20MRD, Cortex-R8, or Cortex-M7; the first piezoelectric sensor 17 and the second piezoelectric sensor 20 can be models of Y-YD-7051, CYB15, or CYZ102); then place the crystal hot-fix rhinestones to be sprayed on the fixed base 13, then open the protective door 11, and slide the fixed base 13 into the two fixed bases through the transfer port 10. Between the fixed slide rails 12; as the fixed seat 13 slides in, the fixed seat 13 will eventually contact the second limiting member 19. At this time, the fixed seat 13 moves into place, the external thrust separates from the fixed seat 13, and the user closes the protective door 11; at the same time, the second piezoelectric sensor 20 on the second limiting member 19 will generate an electrical signal to the controller 18. After receiving the electrical signal sent by the second piezoelectric sensor 20, the controller 18 will determine that the hot rhinestone has moved into place, and after a certain period of time, control the spray pipe 5 and the drive motor 6 to start (the "certain period of time" here is about 1 to 2 minutes, mainly to give the operator time to close the protective door 11); after the time is up, the controller 18 will control the spray pipe 5 and the drive motor 6 to start. Upon startup, the spray pipe 5 will spray a protective film onto the hot-drilled surface through its nozzle (the nozzle of the spray pipe 5 is oriented towards the center of the guide rack 8). Simultaneously, the drive motor 6 will drive the guide gear 9 to rotate. The rotating guide gear 9 will mesh with the guide rack 8. Since the guide rack 8 is fixedly mounted on the spray frame 2, the meshing process between the guide rack 8 and the guide gear 9 will cause the guide gear 9 to move. This movement of the guide gear 9 will drive the drive motor 6 to move. Because the drive motor 6 is slidably mounted on the guide rail 3 via the moving base 4, the moving base 4 can move along with the drive motor 6 and the guide gear 9. The moving seat 4 moves in an arc shape, just like the top surface of the spray frame 2. This allows the moving seat 4 to move in an arc shape. During the movement of the moving seat 4, the spray pipe 5 will also move, allowing the spray pipe 5 to perform multi-angle and multi-face spraying on the hot diamond. When the moving seat 4 reaches the end, it will contact the first piezoelectric sensor 17 on the first limiting member 5. The first piezoelectric sensor 17 will send an electrical signal to the controller 18. The controller 18 will determine that the spraying work has been completed and control the drive motor 6 and the spray pipe 5 to stop. Finally, the operator can open the protective door 11 to take out the hot diamond that has been sprayed.

[0021] When a fixed spraying angle is required, simply move the corresponding first limiting member 15 within the adjusting groove 14, and move it to the required angle through the cooperation of the indicator 16 and the angle scale line on one side of the adjusting groove 14. Then, the controller 18 controls the drive motor 6 to start, so that the guide rack 8 and the guide gear 9 mesh and transmit power. After the moving seat 4 contacts the first limiting member 15, the first piezoelectric sensor 17 will generate an electrical signal to the controller 18, and the controller 18 will control the drive motor 6 to stop, so that the spraying pipe 5 stops moving, thereby completing the adjustment of the spraying angle of the spraying pipe 5.
