DETAILED DESCRIPTION

[0021] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0022] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are only for the purpose of describing specific embodiments and are not intended to limit this invention. Figures 1 to 4As shown, in one embodiment of the present invention, there is provided an automatic pressing and spraying mechanism for a line drawing trolley, comprising a fixed frame 1, a connecting frame 2, a driving assembly 3, a linkage assembly 4 and a pressing element 5. The fixed frame 1 is provided with a placement cavity 11, and the placement cavity 11 is used to install the tank body. The connecting frame 2 is provided on one side of the fixed frame 1, and the driving assembly 3 is provided on the connecting frame 2. One end of the linkage assembly 4 is provided with a hinge element 41, and the hinge element 41 is hinged to one end of the fixed frame 1. The driving end of the driving assembly 3 is connected to the linkage assembly 4 to drive the linkage assembly 4 to move along the hinge element 41. The pressing element 5 is provided on the linkage assembly 4, and when the linkage assembly 4 moves, the pressing element 5 is driven to press the pressing part of the tank body. This embodiment is used to indicate the pre-work of line drawing and make pre-line marks. By means of the placement cavity 11 provided on the fixed frame 1, the spray tank body can be firmly installed to ensure the stability of the tank body and the accuracy of the spraying direction during the spraying process. It not only improves the safety of the spraying operation, but also effectively avoids the problem of uneven spraying caused by the shaking of the tank body. Secondly, the reasonable layout of the connecting frame 2 and the fixing frame 1, as well as the setting of the driving component 3 on the connecting frame 2, provide reliable support and power source for the movement of the entire mechanism. Through precise control, the driving component 3 can drive the linkage component 4 to move flexibly along the hinge element 41. This design enables the pressing component 5 to accurately reach the pressing part of the tank body and realize automatic pressing operation. The design of the hinge element 41 on the linkage component 4 makes the pressing action smoother and continuous, effectively reduces the mechanical shock caused by sudden force, and extends the service life of the equipment. At the same time, the hinged structure also gives the pressing component 5 a certain degree of freedom, so that it can adapt to tanks of different shapes and sizes, improving the versatility and flexibility of the equipment. The efficiency of the spraying operation is significantly improved by the automated press spraying method. Compared with traditional manual press spraying, automated operation not only reduces labor costs, but also greatly improves the uniformity and consistency of spraying, so that the spraying quality is effectively controlled.

[0024] A mounting bracket 12 is provided on one side of the fixing frame 1, and the mounting bracket 12 is used to fix the fixing frame 1 on the frame of the line drawing trolley. Specifically, a mounting hole 13 is provided on the fixing frame 1, and the mounting hole 13 is used to install the mounting bracket 12. A plurality of mounting holes 13 are provided along the length direction of the fixing frame 1 to install the mounting bracket 12 at different positions. In this embodiment, the fixing frame 1 is firmly connected to the frame of the line drawing trolley through the mounting bracket 12 cleverly provided on one side. This design not only enhances the stability of the entire spraying mechanism, but also ensures accurate positioning and reliable operation during the spraying operation. A plurality of mounting holes 13 are carefully arranged along the length direction on the fixing frame 1. This detail treatment gives the mounting bracket 12 a high degree of flexibility in the installation position. Users can select the most suitable mounting hole 13 position for installation according to actual needs, thereby optimizing the layout of the spraying mechanism on the line drawing trolley. This design not only improves the installation efficiency, but also enhances the adaptability and flexibility of the spraying operation. Furthermore, the diverse layout of mounting holes 13 facilitates more even load distribution under varying operating conditions, effectively reducing the risk of deformation or damage to the mounting bracket 1 and mounting bracket 12 due to long-term uneven loading. This not only extends the life of the equipment but also further ensures the accuracy and stability of the automatic pressure spraying mechanism of the marking trolley.

[0025] A fixing assembly 14 is mounted on one end of the mounting bracket 1. This assembly is used to secure the tank within the housing cavity 11. Specifically, the fixing assembly 14 comprises a locking bolt 141, a butterfly nut 142, and a securing clip 143. The locking bolt 141 is used to secure the clip 143, which is mounted on one side of the housing cavity 11. The butterfly nut 142 is connected to one end of the locking bolt 141 to adjust the tension of the clip 143. The securing clip 143 is provided with a securing slot 144 for securing the tank. In this embodiment, the precise coordination of the locking bolt 141, butterfly nut 142, and securing clip 143 ensures the tank is securely fixed within the housing cavity 11. This design not only enhances the tank's stability but also effectively prevents uneven or misaligned spraying caused by the tank's shaking during the spraying process, thereby improving spray quality. Furthermore, the use of the butterfly nut 142 makes adjusting the tension of the securing clip 143 more convenient and efficient. By simply rotating the butterfly nut 142, the operator can quickly adjust the clamping force of the fixing clip 143 on the tank body to accommodate tanks of varying sizes and weights, enhancing the versatility and flexibility of the mechanism. Finally, the fixing slot 144 provided on the fixing clip 143 further enhances the reliability and safety of the tank body's fixation. The slot structure can tightly fit the outer wall of the tank body, effectively preventing the tank body from falling off or shifting due to external forces during the spraying process, ensuring the continuity and stability of the spraying operation.

[0026] A fixed plate 21 is provided on the connecting frame 2, and the fixed plate 21 is used to fix the drive assembly 3. In this embodiment, firstly, the fixed plate 21 serves as a fixing device for the drive assembly 3, ensuring that the drive assembly 3 can remain stable when operating at high speed or under heavy load, effectively preventing malfunctions caused by vibration or looseness. This is of great significance for improving the operating precision and stability of the line drawing trolley, ensuring the accuracy and consistency of the sprayed lines. Secondly, the design of the fixed plate 21 makes the installation and removal of the drive assembly 3 more convenient. When maintaining and replacing the drive assembly 3, the operator can quickly disassemble and assemble it through the fixed plate 21, greatly saving maintenance time and costs. This has a positive effect on ensuring the continuous and efficient operation of the line drawing trolley and improving the utilization rate of the overall equipment. In addition, the fixed plate 21 also has good durability and adaptability, and can adapt to different working environments and operating requirements. Whether it is high temperature, humidity or other harsh conditions, the fixed plate 21 can maintain stable performance, providing a strong guarantee for the long-term stable operation of the line drawing trolley.

[0027] The drive end of the drive assembly 3 is equipped with an articulated connecting rod 31, one end of which is connected to the linkage assembly 4. In this embodiment, through the transmission of the articulated connecting rod 31, the drive assembly 3 can smoothly transmit power to the linkage assembly 4, thereby driving the spray device to perform precise pressing and spraying actions. This flexible transmission method enables the marking trolley to maintain a stable spraying effect in various complex working environments. Secondly, this structure also helps improve the operating efficiency and spraying quality of the marking trolley. Because the design of the articulated connecting rod 31 allows a certain degree of angle variation, it can offset errors caused by uneven work surfaces or irregular workpiece shapes to a certain extent. This ensures that the spray device always maintains optimal contact with the workpiece, ensuring uniform and consistent spraying. In addition, this structure offers the advantages of easy maintenance and adjustment. When the spraying position or angle needs to be adjusted, only the articulated connecting rod 31 needs to be adjusted accordingly, without having to disassemble or replace the entire drive assembly 3. This not only reduces maintenance costs but also improves the reliability and service life of the equipment.

[0028] The linkage assembly 4 is provided with a linkage plate 42, and the linkage plate 42 is provided with a spraying groove 43 facing the placement chamber 11, and the nozzle of the tank body is facing the spraying groove 43. A limiting frame 15 is provided on one side of the fixing frame 1, and a limiting bolt 151 is provided on the limiting frame 15. One end of the limiting bolt 151 is connected to the linkage plate 42. The limiting bolt 151 is located at the limiting frame 15 and the linkage plate 42. A limiting sleeve 152 is provided. The limiting sleeve 152 is used to limit the distance between the limiting frame 15 and the linkage plate 42. Specifically, the pressing element 5 includes a connecting bolt 51 and a pressing sleeve 52 provided on the connecting bolt 51. One end of the connecting bolt 51 is connected to the linkage plate 42, and the pressing sleeve 52 is used to press the pressing part of the tank body. In this embodiment, the linkage plate 42 aligns the spraying groove 43 with the nozzle of the tank body, ensuring the stability and accuracy of the spraying process. The setting of the spraying slot 43 not only optimizes the spraying path, but also enables the paint to be evenly and continuously covered on the target surface, thereby improving the spraying quality and efficiency. Secondly, the combination of the limit frame 15 and the limit bolt 151 provides stable support and adjustment functions for the linkage plate 42. By adjusting the position of the limit bolt 151 on the limit frame 15, the distance between the linkage plate 42 and the fixed frame 1 can be accurately controlled, thereby achieving fine-tuning of the spraying height. This design not only improves the flexibility of the spraying operation, but also ensures that the best spraying effect can be maintained under different working conditions. In addition, the introduction of the pressing element 5 further enhances the degree of automation of the mechanism. The firm connection between the connecting bolt 51 and the linkage plate 42 enables the pressing sleeve 52 to accurately and forcefully press the pressing part of the tank body, thereby triggering the spraying action.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
