Description

Technical Field

[0001] The utility model relates to the technical field of plate-making machines, in particular to a limiting device for a flexographic plate-making machine. Background Art

[0002] A platemaking machine is a prepress equipment that makes plates directly by computer. It uses a digital workflow to directly convert text and images into numbers and directly generate printing plates, eliminating the need for film materials, manual platemaking processes, and semi-automatic or fully automatic platemaking processes. Flexographic printing plates require the use of a flexographic platemaking machine during the printing process.

[0003] According to a Chinese patent with authorized publication number CN215620696U, a CTP platemaking machine adjustment device is disclosed. By setting a limit device and rotating the threaded rod to allow the threaded rod to drive the block to slide to limit the template position, not only the template position limit is completed, but also the position of the entire device can be changed according to the size of the template. The device solves the problem that the traditional placement plate has no limiter and the printing effect is poor due to incorrect placement position.

[0004] Although the above scheme solves the problem of template limitation in actual use, the device still requires workers to push the template into the platemaking machine after it is limited during the loading process, which increases the labor intensity of the workers and affects the loading speed, thereby affecting the working efficiency of the flexographic platemaking machine, reducing production capacity, and reducing the practicality of the existing platemaking machine.

[0015] Furthermore, an adjustment hole is opened at the top of the mounting frame, the connecting plate is slidably connected inside the adjustment hole, and the bottom of the connecting plate is fixed to the top of the mounting plate.

[0019] Furthermore, two convex grooves are provided at the bottom of the mounting plate, and the convex blocks are slidably connected in the convex grooves.

[0021] Furthermore, the top of the limit block is fixed to the top of the movable plate, and the top of the adjustment rod is in close contact with the bottom of the movable plate.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0033] See also Figure 1-4 The utility model provides a technical solution: a limiting device for a flexographic platemaking machine, comprising a machine body 1, a placement plate 2 fixed to the front of the machine body 1, a mounting frame 3 fixed to the top of the placement plate 2, a limiting feeding mechanism 200 installed at the bottom of the mounting frame 3 for limiting and pushing the flexographic plate, and an adjusting component 300 installed at the top of the mounting frame 3 for driving the limiting feeding mechanism 200 to move left and right;

[0034] Through the coordinated use of the machine body 1, the placement plate 2, the mounting frame 3, the limiting feeding mechanism 200 and the adjusting assembly 300, in actual use, while limiting the position of the flexographic plate, it can also be automatically pushed into the platemaking machine after limiting. There is no need for workers to manually push the limited flexographic plate into the platemaking machine, thereby reducing the labor intensity of the workers and effectively increasing the loading speed, thereby improving the working efficiency of the flexographic platemaking machine and improving the practicality of the limiting device for the flexographic platemaking machine.

[0035] In this embodiment, the position limiting feeding mechanism 200 is a structure for limiting and pushing the flexographic plate.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the limiting feed mechanism 200 includes a mounting plate 201 slidably connected to the inner top wall of the mounting frame 3, a feed assembly 202 installed at the bottom of the mounting plate 201 for pushing the flexible plate into the machine body 1, and a limiting assembly 203 installed at the bottom of the mounting plate 201 for limiting the flexible plate.

[0037] In this embodiment, the feeding assembly 202 is a structure for pushing the flexographic plate into the machine body 1 .

[0038] like Figure 1 , Figure 2 and Figure 3As shown, the feed assembly 202 includes a movable plate 2021 slidably connected to the bottom of the mounting plate 201, two convex blocks 2022 fixed to the top of the movable plate 2021, a motor 2024 fixed to the bottom of the mounting plate 201, a main screw 2025 fixed to the output shaft of the motor 2024, an adjusting rod 2026 threadedly connected to the outside of the main screw 2025, two limit rods 2027 respectively fixed to the left and right sides of the adjusting rod 2026, and limit blocks 2028 respectively fixed to the opposite ends of the two limit rods 2027.

[0039] It should be noted that two convex grooves 2023 are provided at the bottom of the mounting plate 201 , and the convex blocks 2022 are slidably connected in the convex grooves 2023 , so that the movable plate 2021 is more stable when being adjusted forward and backward through the convex grooves 2023 and the convex blocks 2022 .

[0040] In addition, the adjustable distance of the convex block 2022 in the convex groove 2023 is smaller than the adjustable distance of the main screw rod 2025 in the adjustment rod 2026, so as to avoid the main screw rod 2025 and the adjustment rod 2026 falling off and thus failing to achieve the expected use effect.

[0041] In addition, the top of the limit block 2028 is fixed to the top of the movable plate 2021, and the top of the adjustment rod 2026 is in close contact with the bottom of the movable plate 2021, ensuring that the adjustment rod 2026 can be effectively limited so that it can be moved back and forth on the outside of the screw 2025 for adjustment.

[0042] In this embodiment, the limiting component 203 is a structure for effectively limiting the position of the flexographic plate.

[0043] like Figure 1 , Figure 2 and Figure 4 As shown, the limiting assembly 203 includes two vertical plates 2031 respectively fixedly connected to the left and right sides of the movable plate 2021, two electric telescopic rods 2032 respectively fixed to the opposite sides of the two vertical plates 2031, two fixed columns 2033 respectively fixed to the opposite ends of the two electric telescopic rods 2032, and a limiting plate 2034 fixed to the bottom end of the fixed column 2033.

[0044] It should be noted that the top of the vertical plate 2031 is slidably connected to the bottom of the mounting plate 201, so that the vertical plate 2031 is more stable when moving forward and backward, and the bottom of the limiting plate 2034 is slidably connected to the top of the placement plate 2, ensuring that the limiting plate 2034 can limit the flexible plate on the top of the placement plate 2.

[0045] In this embodiment, the adjustment component 300 is a structure that drives the limiting feeding mechanism 200 to move left and right for adjustment.

[0046] like Figure 1 and Figure 3As shown, the adjustment assembly 300 includes a connecting plate 301 fixed to the top of the mounting plate 201 and an adjustment plate 302 fixed to the top of the connecting plate 301 .

[0047] It should be noted that an adjustment hole 303 is opened at the top of the mounting frame 3, and the connecting plate 301 is slidably connected inside the adjustment hole 303. The bottom of the connecting plate 301 is fixed to the top of the mounting plate 201 to ensure that the mounting plate 201 can be moved left and right by the connecting plate 301.

[0048] In addition, the width of the adjustment plate 302 is greater than the width of the connecting plate 301, so that the adjustment plate 302 is more stable when moving left and right. A plurality of fixing grooves 304 are provided on the top of the mounting frame 3 to facilitate fixing the adjustment plate 302 by bolts.

[0049] The working principle of the above embodiment is:

[0050] When in use, first place the flexographic plate to be printed on the placement plate 2 in the machine body 1, and then according to the position and size of the flexographic plate, move the adjustment plate 302 left and right to adjust, so as to drive the mounting plate 201 to move left and right through the connecting plate 301. After moving to the designated location, fix the adjustment plate 302 and the mounting frame 3 by bolts, and then turn on the electric telescopic rod 2032 to drive the two fixing columns 2033 to move closer to or away from each other, thereby driving the two limiting plates 2034 to move closer to or away from each other, so as to limit the flexographic plate through the two limiting plates 2034, and then turn on the motor 2024. The main screw rod 2025 is driven to rotate in place, and the adjusting rod 2026 is moved forward and backward on the outside of the main screw rod 2025 under the rotation thrust of the internal thread and the limiting action of the limiting rod 2027, so that the movable plate 2021 is driven to move forward and backward through the limiting block 2028, so that the limiting plate 2034 is driven to move forward and backward through the vertical plate 2031 and the fixed column 2033, so as to drive the flexible plate to move forward and backward, so as to automatically push the flexible plate into the body 1, and at the same time, under the action of the convex block 2022 and the convex groove 2023, the movable plate 2021 is moved forward and backward to make it more stable.

[0051] Compared with the prior art, the limiting device for the flexographic platemaking machine, through the coordinated use of the machine body 1, the placement plate 2, the mounting frame 3, the limiting feeding mechanism 200 and the adjusting assembly 300, can limit the flexographic plate and automatically push it into the platemaking machine after limiting it during actual use. There is no need for workers to manually push the limited flexographic plate into the platemaking machine, thereby reducing the labor intensity of the workers and effectively increasing the loading speed, thereby improving the working efficiency of the flexographic platemaking machine, improving the practicality of the limiting device for the flexographic platemaking machine, and solving the problem of low practicality of the existing platemaking machine.

[0052] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of an external power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.
