Description

Technical Field

[0001] This invention relates to the field of craft dispensing technology, specifically to an adjustable dispensing device and a universal joint dispensing head for the edge of a sandblasted standee. Background Technology

[0002] In the field of craft manufacturing, especially in the production of crafts involving gaps that need to be sealed or glued, such as sandblasted standees, dispensing technology is a key process. Sandblasted standees are usually made by interlocking two or more pieces, and the gaps after merging need to be precisely treated with dispensing to ensure the stability and aesthetics of the structure.

[0003] However, existing dispensing devices, when dispensing adhesive into the gaps at the edges of sandblasted standees, mostly have fixed dispensing heads or can only move within a limited range. They cannot automatically and flexibly adjust to the actual shape of the sandblasted standee's edge, affecting dispensing quality and efficiency. Therefore, in order to address the above problems, an adjustable dispensing device and a universal joint dispensing head for the edge of a sandblasting sign are proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable dispensing device and a universal joint dispensing head for the edge of a sandblasted sign.

[0005] The objective of this invention is achieved through the following technical solution: an adjustable dispensing device for the edge of a sandblasting stand, comprising a dispensing head, a dispensing mechanism for injecting glue, and a limiting frame. The limiting frame has a movable groove. The middle of the limiting frame is fixed to the sandblasting stand by a pressing member. A telescopic plate is rotatably connected to the middle of the limiting frame. A telescopic member is hinged to the telescopic end of the telescopic plate. A movable plate connected to the dispensing head is rotatably connected to the telescopic end of the telescopic member. Two movable columns are hinged to the movable plate. The two movable columns are rotatably connected by a rotating shaft. A locking plate that engages with the movable groove is fixedly connected to the end of the movable column. It also includes a fixing component to ensure the size of the gap between the rotating shaft and the telescopic component. The rotating shaft slides within the movable groove, providing high flexibility and precise positioning.

[0006] As a further description of the above technical solution: the dispensing mechanism includes a storage tank and an injection device located inside the storage tank. The injection device injects the glue in the storage tank into the dispensing head through an elastic pipe. The storage tank is connected and fixed to the shell of the telescopic component, providing stable glue supply and enabling large-capacity storage.

[0007] As a further description of the above technical solution: a motor is fixedly connected to the middle of the limiting frame, the output shaft of the motor is fixedly connected to the telescopic plate, and the pressing component includes two pressing plates located in the middle of the quicksand stand. One pressing plate is rotatably connected to the output shaft of the motor, and the other pressing plate is connected to the limiting frame through a telescopic tube rod with an internal compression spring.

[0008] As a further description of the above technical solution: the two pressure plates are magnetically attracted plates, and the contact surface with the sand-filled stand is provided with an anti-slip layer. Multiple U-shaped reinforcing plates are fixedly connected to the limiting frame to enhance the fixing effect and improve the strength of the equipment.

[0009] As a further description of the above technical solution: the fixing component includes an L-shaped plate that is connected and fixed to the shell of the telescopic component. The end of the L-shaped plate is fixedly connected to a limiting plate that passes through two movable columns to maintain a certain distance, so as to facilitate the precise rotation of the clamping plate in and out.

[0010] As a further description of the above technical solution: the movable column includes a conical rotating column and a mating column. The mating column is hinged to the movable plate by a hinge plate, and the mating column has a mating groove in the middle that mates with the limiting plate.

[0011] As a further description of the above technical solution: the end of the card plate has a wedge-shaped structure, and the telescopic end of the telescopic component is fixedly connected to an L-shaped elastic rod. A compression component is hung between the L-shaped elastic rod and the movable plate. The L-shaped elastic rod slides in contact with the L-shaped plate to achieve automatic reset.

[0012] A universal joint type dispensing head for an adjustable dispensing device at the edge of a sandblasted standee, characterized in that, applied to the aforementioned adjustable dispensing device at the edge of a sandblasted standee, includes: a dispensing head body and an injection needle, and further includes an elastic telescopic mechanism, the two ends of which are respectively connected to a movable plate and the dispensing head body, the dispensing head body and the injection needle are connected by a universal joint, the universal joint is fixed by a screw, and the injection needle is also provided with a U-shaped pressing element.

[0013] Compared with the prior art, the advantages of the present invention are as follows: This invention designs an adjustable dispensing device, including a rotating telescopic plate, telescopic components, and a movable plate, which enables the dispensing head to move flexibly and adjust its angle in three-dimensional space.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figures 1-9 The diagram shows an embodiment of an adjustable dispensing device for the edge of a quicksand stand provided by the present invention. It includes a dispensing head, a dispensing mechanism for injecting adhesive, and a limiting frame 1. The limiting frame 1 has a movable groove 2. The quicksand stand is fixed in the middle of the limiting frame 1 by a pressing member. A telescopic plate 3 is rotatably connected to the middle of the limiting frame 1. A telescopic member 4 is hinged to the telescopic end of the telescopic plate 3. The telescopic end of the telescopic plate 3 is actually hinged to a storage tank 9. A movable plate 5 connected to the dispensing head is rotatably connected to the telescopic end of the telescopic member 4. Two movable columns 6 are hinged to the movable plate 5. The storage tank 9 is fixed to the telescopic member 4. Therefore, the telescopic plate... The telescopic end of 3 is hinged to the telescopic component 4. Although the two do not directly contact each other, the two movable columns 6 are rotatably connected by a rotating shaft 7. The end of the movable column 6 is fixedly connected to a locking plate 8 that engages with the movable groove 2. It also includes a fixing component to ensure the size of the distance between the rotating shaft 7 and the telescopic component 4. The rotating shaft 7 slides in the movable groove 2. Through the combined design of the telescopic plate 3 and the telescopic component 4, the dispensing head can move flexibly in three-dimensional space to adapt to the dispensing needs of the edges of the quicksand stand with different shapes and sizes. The design of the movable groove 2 and the locking plate 8 ensures the accurate positioning of the dispensing head during the movement process and improves the dispensing accuracy.

[0017] The dispensing mechanism includes a storage tank 9 (which can be periodically filled with glue and is a large-capacity tank) and an injection device located inside the storage tank 9. The injection device injects the glue from the storage tank 9 into the dispensing head through an elastic pipe 10. The storage tank 9 is connected and fixed to the shell of the telescopic component 4. The design of the injection device and the elastic pipe 10 ensures a stable supply of glue and avoids the impact of glue supply interruption or fluctuation on dispensing quality. The storage tank 9 is designed to be large-capacity, which reduces the number of times glue needs to be added and improves production efficiency.

[0018] A motor 11 is fixedly connected to the middle of the limiting frame 1. The output shaft of the motor 11 is connected and fixed to the telescopic plate 3. The pressing component includes two pressing plates 12 located in the middle of the sandblasted stand. One pressing plate 12 is rotatably connected to the output shaft of the motor 11, and the other pressing plate 12 is connected to the limiting frame 1 through a telescopic tube 13 with an internal compression spring. The motor 11 drives the telescopic plate 3 to rotate, which drives the dispensing head to move automatically along the edge of the sandblasted stand, realizing automated dispensing. The pressing component, through the design of the compression spring and the telescopic tube 13, can tightly press the sandblasted stand, ensuring its stability during the dispensing process.

[0019] It is worth noting that the two pressure plates 12 are magnetically attracted plates, and the contact surface with the sandblasted stand is provided with an anti-slip layer. Multiple U-shaped reinforcing plates 14 are fixedly connected to the limiting frame 1. The design of magnetic attraction and anti-slip layer further enhances the fixing effect of the pressure plates 12 on the sandblasted stand, preventing displacement during the dispensing process. The design of U-shaped reinforcing plates 14 improves the strength and stability of the limiting frame 1, ensuring the reliability of the equipment during long-term operation.

[0020] The fixing component includes an L-shaped plate 15 that is fixedly connected to the shell of the telescopic component 4. A limiting plate 16 that passes through two movable columns 6 is fixedly connected to the end of the L-shaped plate 15. The design of the limiting plate 16 ensures that the distance between the rotating shaft 7 and the telescopic component 4 is always consistent, preventing the decrease in dispensing accuracy caused by changes in distance during the dispensing process.

[0021] The movable column 6 includes a conical rotating column 601 and a mating column 602. The mating column 602 is hinged to the movable plate 5 by a hinge plate 17. The mating column 602 has a mating groove 603 in the middle that mates with the limiting plate 16. The mating groove 603 and the limiting plate 16 are designed to ensure the accurate positioning of the movable column 6 during rotation and improve the dispensing accuracy.

[0022] It should be noted that: the end of the card plate 8 has a wedge-shaped structure, and the telescopic end of the telescopic component 4 is fixedly connected to an L-shaped elastic rod 18. A compression component 19 is hung between the L-shaped elastic rod 18 and the movable plate 5. The L-shaped elastic rod 18 slides in contact with the L-shaped plate 15. The design of the wedge-shaped card plate 8 allows the dispensing head to pass smoothly through the bend of the movable groove 2, realizing the continuity and stability of the dispensing path. In addition, the design of the L-shaped elastic rod 18 and the compression component 19 allows the movable plate 5 to quickly reset after passing through the bend, ensuring the accurate return of the dispensing head and the precision of subsequent dispensing.

[0023] A universal joint type dispensing head for an adjustable dispensing device at the edge of a sandblasted standee, characterized in that, applied to the aforementioned adjustable dispensing device at the edge of a sandblasted standee, it includes: a dispensing head body 20 and an injection needle 21, and further includes an elastic telescopic mechanism 22, the two ends of which are respectively connected to a movable plate 5 and the dispensing head body 20, the dispensing head body 20 and the injection needle 21 are connected by a universal joint 23, the universal joint 23 is fixed by a screw, and the injection needle 21 is also provided with a U-shaped pressing member 24.

[0024] Working principle: First, two sandblasted standees are inserted and merged (there are interlocking posts and slots between the two sandblasted standees), and the merged sandblasted standees are placed between two pressure plates 12. Through the action of the telescopic tube 13 with internal compression spring, the two pressure plates 12 tightly press against the sandblasted standees, and the magnetic attraction further ensures the position of the sandblasted standees, so that the gap between the two sandblasted standees corresponds to the position of the glue dispensing head, which facilitates the glue dispensing head to inject glue into the gap; Then start motor 11. Motor 11 rotates slowly and evenly, driving telescopic plate 3 to rotate while making adaptive extension and retraction, thereby ensuring that card plate 8 moves horizontally along the top of movable groove 2. Hinged plate 17, storage box 9 and movable plate 5 all move horizontally. The glue dispensing head moves slowly and horizontally to inject glue into the gap at the top of the sand stand. It is worth noting that the L-shaped plate 15 and the limiting plate 16 restrict the distance between the rotating shaft 7 and the telescopic plate 3, so that the rotating shaft 7 always moves within the movable groove 2. Next, when the card plate 8 and the movable column 6 move to the bend of the movable groove 2 (i.e., the junction of the horizontal and vertical sections of the movable groove 2), the telescopic component 4 (electric telescopic rod) is activated. The telescopic end of the telescopic component 4 extends, driving the movable plate 5 to move towards the limiting frame 1, thereby causing the rotating column 601 and the mating column 602 to rotate (rotating around the rotating shaft 7). The two mating columns 602 move away from each other, thereby causing the card plate 8 to rotate (also rotating around the rotating shaft 7), so that the card plate 8 can disengage from the movable groove 2 to smoothly pass through the bend of the movable groove 2. At this time, the glue dispensing head disengages from the gap of the sand-filled stand (at this time, the glue dispensing head stops injecting glue).

[0025] After passing through the bend of the movable groove 2, the telescopic component 4 retracts, thereby resetting the dispensing head to the gap of the sandblasted stand. The rotating column 601 and the mating column 602 rotate (rotating with the rotating shaft 7 as the center of rotation). The two mating columns 602 move closer to each other, thereby causing the clamping plate 8 to be inserted into the movable groove 2. Since the end of the clamping plate 8 has a wedge-shaped structure, it automatically corrects and enters the movable groove. It is worth noting that: while the telescopic component 4 retracts, the output shaft end of the telescopic component 4 and the L-shaped elastic rod 18 move relative to the L-shaped plate 15. Under the pressure of the L-shaped plate 15, the inclined L-shaped elastic rod 18, in conjunction with the action of the compression component 19, promotes the rotation of the movable plate 5 (the movable plate 5 always has a force in the same clockwise direction relative to the L-shaped plate 15), thereby causing the movable plate 5 to switch, driving the dispensing head to switch to a horizontal state, so that the dispensing head presses against the vertical gap of the sand-filled stand. Repeat this process to complete the application of adhesive to the gaps around the sandblasted signboard.

[0026] Finally, remove the sand-retaining plaque from between the two pressure plates 12.

[0027] The elastic telescopic mechanism 22 ensures that the U-shaped pressing member 24 presses against the sandblasted stand, and the distance between the injection needle 21 and the gap of the sandblasted stand is kept consistent.
