Description

Technical Field

[0001] This utility model relates to the field of umbrella production technology, and in particular to an umbrella surface printing equipment. Background Technology

[0002] An umbrella is a tool for providing shade from the sun or shielding against rain and snow. It is generally made of oiled paper, oilcloth, or plastic sheeting. The materials used to make an umbrella typically include stretchable fabric, other materials used for the frame, and binding thread. It is held up by hand. Although the umbrella was originally invented primarily to block sunlight, it is most commonly used as a tool to protect against rain. Other uses for umbrellas include as decorations, walking sticks, and even weapons. The long-established Leung So Kee umbrellas in Hong Kong are one example of umbrellas that can be used as weapons. There are three main types of fabric used for umbrellas, in order of cost from lowest to highest: polyester, PG fabric, nylon, and transparent plastic.

[0003] Nowadays, umbrellas come in all shapes and sizes, which is inseparable from the use of umbrella surface printing equipment. However, the existing technology has many shortcomings. The printing process is cumbersome, the work progress is slow and inefficient, the workload is high, the umbrella surface is not firmly fixed, deviations are prone to occur during the printing process, which greatly affects the printing quality. It cannot adapt to the printing needs of umbrella surfaces of different sizes and positions, reducing work efficiency and making it impossible to print on any position of the umbrella surface.

[0004] In view of this, the inventor tirelessly conducted research and improvement, and after many tests and improvements, finally developed a production equipment for printing on umbrella surfaces. Utility Model Content

[0005] The purpose of this invention is to provide an umbrella surface printing device that can achieve precise printing on umbrella surfaces and has high adjustability and stability.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an umbrella surface printing device, including a mounting base, a worktable provided on the upper surface of the mounting base, a fixing structure disposed on the worktable, and a plurality of spaced openings provided on the worktable along its circumference, and further including a lateral adjustment structure, a fixing structure, a longitudinal adjustment structure and a printing structure, the lateral adjustment structure disposed on the upper surface of the mounting base, the fixing structure disposed on the upper surface of the worktable, and the printing structure disposed on the lower surface of the longitudinal adjustment structure.

[0007] By adopting the above technical solution, the mounting base and worktable provide a stable support foundation for the entire equipment, and the worktable enhances the load-bearing capacity of the umbrella surface. The combination of the horizontal and vertical adjustment structures allows the printing structure to be flexibly adjusted in both horizontal and vertical directions to adapt to the printing needs of umbrella surfaces of different sizes and positions, while the fixing structure is used to stably fix the umbrella surface, ensuring accuracy and stability during the printing process.

[0008] The lateral adjustment structure is further configured as follows: a slide rail located on both sides of the worktable, a movable rod slidably disposed on the slide rail, a first drive structure for driving the movable rod to move along the length direction of the slide rail, a connecting groove located between the two movable rods and fixedly connected to the two movable rods, a first telescopic cylinder disposed in the connecting groove, and a second drive structure for driving the first telescopic cylinder to reciprocate along the length direction of the connecting groove.

[0009] By adopting the above technical solution, the cooperation between the slide rail and the moving rod allows the lateral adjustment structure to move flexibly in the horizontal direction, and the first drive structure provides power to the moving rod. The setting of the connecting groove and the first telescopic cylinder allows the printing structure to be further fine-tuned in the horizontal direction, and the second drive structure drives the first telescopic cylinder to reciprocate within the connecting groove, achieving more precise lateral adjustment.

[0010] The first drive structure is further configured such that: a first adjusting motor is fixedly disposed on the upper surface of the mounting base plate and a first adjusting screw is fixedly connected to the output end of the first adjusting motor, and the first adjusting screw is threadedly connected to the moving rod.

[0011] By adopting the above technical solution, the first adjusting motor drives the first adjusting screw to rotate. Since the first adjusting screw is threadedly connected to the moving rod, the moving rod can move along the length direction of the first adjusting screw on the slide rail to achieve lateral adjustment.

[0012] The second drive structure is further configured as follows: a second adjusting motor is fixedly mounted on the upper side of the moving rod, a sliding groove is provided on the inner side of the connecting groove, and a second adjusting screw is provided in the sliding groove. The output end of the second adjusting motor passes through the moving rod, extends into the sliding groove, and is fixedly connected to one end of the second adjusting screw. The other end of the second adjusting screw is rotatably connected to the inner wall of the connecting groove through a bearing.

[0013] By adopting the above technical solution, the second adjusting motor drives the second adjusting screw to rotate. Since the second adjusting screw is threadedly connected to the first telescopic cylinder, the first telescopic cylinder can move along the length direction of the second adjusting screw in the slide groove, thereby achieving more precise lateral adjustment.

[0014] The longitudinal adjustment structure is further configured such that a first telescopic cylinder is slidably disposed within the groove along its length, the first telescopic cylinder is threadedly connected to a second adjusting screw, and the printing structure is disposed at the output end of the first telescopic cylinder.

[0015] By adopting the above technical solution, the telescopic movement of the first telescopic cylinder enables the printing structure to be flexibly adjusted in the vertical direction to adapt to the printing needs of umbrella surfaces at different heights.

[0016] The fixing structure is further configured as follows: the fixing structure includes several spaced openings along the circumference of the workbench, an L-shaped clamp plate passing through the openings and used to fix the umbrella surface, a linkage frame, and a locking structure. The lower plate of the L-shaped clamp plate passes through the openings and is slidably connected to the openings. The lower plate of each L-shaped clamp plate is fixedly connected to the linkage frame. The locking structure is disposed between the linkage frame and the mounting base plate.

[0017] By adopting the above technical solution, the user provides sliding and clamping functions for the L-shaped clamps. The L-shaped clamps are used to clamp the umbrella surface. The linkage frame connects multiple L-shaped clamps together, and the locking structure is used to fix the linkage frame on the mounting base plate to ensure the stability of the umbrella surface during the printing process.

[0018] The locking structure is further configured as follows: a locking groove is provided on one side of the lower part of the linkage frame, a locking block is provided below the locking groove, a slide and a stop block are fixedly provided on the end face of the mounting base plate, and an inclined slope is formed on the side of the locking groove facing the locking block below the orthogonal projection of the locking groove. The locking block is slidably provided on the slide. A drive spring is sleeved on one end of the locking block facing away from the inclined slope. The two ends of the drive spring are fixedly connected to the stop block and the locking block respectively. When the locking groove and the locking block are directly aligned, the drive spring drives the locking block to move toward the locking groove and engage accordingly.

[0019] By adopting the above technical solution, when the linkage frame descends to a certain position, the lock groove and the lock block correspond to each other. The drive spring drives the lock block to move toward the lock groove and engage, thereby fixing the linkage frame on the mounting plate. The inclined slope setting allows the lock block to slide smoothly into the lock groove during the movement, making it easy for the lock block to lock in the lock groove.

[0020] The lock block is further configured such that a pull handle is fixedly connected to one side of the lock block, and a return spring is sleeved on the lower part of the linkage frame. The two ends of the return spring are fixedly connected to the linkage frame and the mounting base plate, respectively. When the pull handle is pulled to move away from the lock groove, the lock block disengages from the lock groove, and the return spring moves the linkage frame upward.

[0021] By adopting the above technical solution, the pull handle facilitates the manual unlocking process of the lock block. The return spring ensures that after unlocking, the linkage frame can automatically rise to the initial position, facilitating the next umbrella surface fixing and printing operation.
