Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically to a material receiving device for a high-speed printing press. Background Technology

[0002] In existing technology, operators usually apply tape to the beginning of a new roll of film and rotate the new roll to the ready-to-join position. Then, they automatically change the roll by pressing the join button. However, the accuracy of the determination of the tape position on the new roll directly affects the success rate of film joining. Since it is difficult to accurately identify the tape position when the roll is rotating at high speed, the error of manual judgment is large, which often leads to roll changing failure, resulting in equipment downtime and seriously affecting the production efficiency of the equipment. Utility Model Content

[0003] To address the shortcomings of existing technologies, such as the difficulty in accurately identifying the tape position during high-speed film rotation, which leads to significant errors in manual judgment and frequent roll change failures, resulting in equipment downtime and severely impacting production efficiency, this invention provides a material receiving device for high-speed printing machines.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a material receiving device for a high-speed printing machine, including an unwinding frame, a printing machine body, a work frame disposed on the inner side wall of the unwinding frame, and a support frame disposed on the inner side wall of the printing machine body. A film changing execution component for performing film changing operations is disposed on one side of the inner side wall of the work frame, and a drive component for driving the film changing execution component to perform film changing is disposed on the outer side wall of the work frame.

[0006] The inner wall of the support frame is rotatably connected to a first air shaft for supporting the new film after replacement on the side closest to the film replacement execution component. The inner wall of the support frame is rotatably connected to a second air shaft for supporting the old film to be replaced on the side away from the first air shaft. A collar is provided on one side of the outer wall of the first air shaft. A reflector is provided on the collar. A reflective photoelectric sensor that works with the reflector and is electrically connected to the drive component is provided on the work frame.

[0007] As a preferred technical solution of this utility model, the film changing execution component includes a first rotating rod rotatably connected to one side of the inner wall of the work frame, and a first support plate fixedly connected to both ends of the outer wall of the first rotating rod. A pressure roller is rotatably connected to the end of the two first support plates away from the first rotating rod.

[0008] As a preferred technical solution of this utility model, the film changing execution component further includes a second rotating rod rotatably connected to one side of the inner wall of the work frame. The second rotating rod has two second support plates fixedly connected to both sides of its outer wall. A cutting knife is fixedly connected to one end of the inner wall of the two second support plates away from the second rotating rod.

[0009] As a preferred embodiment of the present invention, the driving assembly includes a first electric push rod rotatably connected to one side of the outer wall of the work frame. The end of the first rotating rod near the first electric push rod passes through the work frame and is fixedly connected to a first connecting plate. The output end of the first electric push rod is fixedly connected to the side of the outer wall of the first connecting plate away from the first rotating rod.

[0010] As a preferred embodiment of the present invention, the drive assembly further includes a second electric push rod rotatably connected to one side of the outer wall of the work frame. The end of the second electric push rod near the second electric push rod passes through the work frame and is fixedly connected to a second connecting plate. The output end of the second electric push rod is fixedly connected to the side of the outer wall of the second connecting plate away from the second electric push rod.

[0011] As a preferred embodiment of this utility model, a threaded hole is provided on one side of the outer wall of the collar, and a fastening bolt is threaded into the threaded hole.

[0012] As a preferred embodiment of this utility model, auxiliary support rollers are rotatably connected to both sides of the inner wall of the support frame.

[0013] In summary, this application has the following beneficial effects:

[0014] 1. This application utilizes the cooperation of an unwinding frame, printing machine body, work frame, support frame, film changing execution component, drive component, first air shaft, second air shaft, collar, reflector, and reflective photoelectric sensor. When a new film needs to be replaced, pressing the start button of the start / stop button puts the reflective photoelectric sensor into a ready-to-trigger state. When the reflector rotates to a preset angle position, the reflective photoelectric sensor detects the reflected signal and triggers, driving the drive component to drive the film changing execution component to change the film. This minimizes the risk of equipment downtime due to misjudgment during manual roll changing, which would severely impact equipment production efficiency.

[0015] 2. This application utilizes the combination of a collar, a reflector, a threaded hole, and a fastening bolt. When it is necessary to adjust the circumferential and axial positions of the reflector on the first air expansion shaft, the fastening bolt can be rotated first to move it away from the first air expansion shaft. Then, the collar can be slid and rotated along the first air expansion shaft as needed. After the reflector is adjusted, the fastening bolt can be rotated again until it re-engages with the first air expansion shaft, thus completing the positioning of the reflector. This enables the adjustment of the trigger point during film replacement, improving the practicality of the device. Attached Figure Description

Detailed Implementation

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Refer to Figure 1 , Figure 2 and Figure 3 The present invention relates to a receiving device for a high-speed printing machine, comprising an unwinding frame 1, a printing machine body 2, a work frame 3 disposed on the inner side wall of the unwinding frame 1, and a support frame 4 disposed on the inner side wall of the printing machine body 2. A film changing execution component 5 for performing film changing operation is disposed on one side of the inner side wall of the work frame 3, and a drive component 6 for driving the film changing execution component 5 to perform film changing is disposed on the outer side wall of the work frame 3.

[0024] The film changing execution assembly 5 includes a first rotating rod 51 rotatably connected to one side of the inner wall of the work frame 3. Both ends of the outer wall of the first rotating rod 51 are fixedly connected to a first support plate 52. A pressure roller 53 is rotatably connected to one end of the two first support plates 52 away from the first rotating rod 51. When the first rotating rod 51 rotates, the pressure roller 53 can be driven to perform a circular motion around the first rotating rod 51 as the axis through the first support plate 52.

[0025] The drive assembly 6 includes a first electric push rod 61 rotatably connected to one side of the outer wall of the work frame 3. One end of the first rotating rod 51 near the first electric push rod 61 passes through the work frame 3 and is fixedly connected to a first connecting plate 62. The output end of the first electric push rod 61 is fixedly connected to the side of the outer wall of the first connecting plate 62 away from the first rotating rod 51. The first electric push rod 61 can drive the first connecting plate 62 to rotate around the first rotating rod 51 as the axis by the extension and retraction of the output end, thereby driving the first rotating rod 51 to rotate.

[0026] Reference Figure 1 and Figure 2 The film changing execution component 5 also includes a second rotating rod 54 rotatably connected to one side of the inner wall of the work frame 3. The two sides of the outer wall of the second rotating rod 54 are fixedly connected to the second support plate 55. The end of the inner wall of the two second support plates 55 away from the second rotating rod 54 is fixedly connected to the cutter 56. When the second rotating rod 54 rotates, the cutter 56 can be driven to perform circular motion around the second rotating rod 54 as the axis through the second support plate 55.

[0027] The drive assembly 6 also includes a second electric push rod 63 rotatably connected to one side of the outer wall of the work frame 3. The end of the second rotating rod 54 near the second electric push rod 63 passes through the work frame 3 and is fixedly connected to a second connecting plate 64. The output end of the second electric push rod 63 is fixedly connected to the side of the outer wall of the second connecting plate 64 away from the second rotating rod 54. The second electric push rod 63 can drive the second connecting plate 64 to rotate around the second rotating rod 54 as the axis by the extension and retraction of the output end, thereby driving the second rotating rod 54 to rotate.

[0028] Reference Figure 1 and Figure 3 The inner wall of the support frame 4 is rotatably connected to a first air shaft 7 for supporting the new film after replacement on the side close to the film replacement execution component 5. The inner wall of the support frame 4 is rotatably connected to a second air shaft 8 for supporting the old film to be replaced on the side away from the first air shaft 7. Auxiliary support rollers 14 are rotatably connected to both sides of the inner wall of the support frame 4. A collar 9 is provided on one side of the outer wall of the first air shaft 7. A threaded hole 12 is opened on one side of the outer wall of the collar 9. A fastening bolt 13 is threaded in the threaded hole 12. A reflector 10 is provided on the collar 9. When it is necessary to adjust the circumferential and axial positions of the reflector 10 on the first air shaft 7, the fastening bolt 13 can be rotated first to move the fastening bolt 13 away from the first air shaft 7. Then, the collar 9 can be slid and rotated along the first air shaft 7 as needed. After the reflector 10 is adjusted, the fastening bolt 13 is rotated again until the fastening bolt 13 abuts against the first air shaft 7 again to complete the positioning of the reflector 10.

[0029] The work frame 3 is equipped with a reflective photoelectric sensor 11 that works in conjunction with the reflector 10 and is electrically connected to the drive assembly 6. The outer wall of the unwinding frame 1 is also equipped with a start / stop button for starting and stopping the photoelectric sensor 11 and is electrically connected to the photoelectric sensor 11. During normal use, the second air shaft 8 continuously unwinds the film, the first air shaft 7 drives the new film to rotate, the collar 9 set on the first air shaft 7 rotates synchronously, and the reflector 10 set on the collar 9 periodically aligns with the field of view of the reflective photoelectric sensor 11. The old film to be replaced crosses the auxiliary support roller 14 and enters the printing machine. When a new film needs to be replaced, the start position of the start / stop button is pressed, so that the reflective photoelectric sensor 11 enters the ready-to-trigger state. When the reflector 10 rotates to the preset angle position, the reflective photoelectric sensor 11 detects the reflection signal and is triggered, which further drives the first electric push rod 61 and the second electric push rod 63 to start.

[0030] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0031] The implementation principle of this utility model is as follows:

[0032] During operation, under normal use, the second air shaft 8 continuously unwinds the film, the first air shaft 7 drives the new film to rotate, the collar 9 set on the first air shaft 7 rotates synchronously, and the reflector 10 set on the collar 9 periodically aligns with the field of view of the reflective photoelectric sensor 11. When the old film to be replaced crosses the auxiliary support roller 14 and enters the printing machine, when a new film needs to be replaced, the start position of the start / stop button is pressed, so that the reflective photoelectric sensor 11 enters the ready-to-trigger state. When the reflector 10 rotates to the preset angle position, the reflective photoelectric sensor 11 detects the reflection signal and triggers, and further drives the first electric push rod 61 and the second electric push rod 63 to start.

[0033] When the first electric actuator 61 is started, the extension and retraction of the output end drives the first connecting plate 62 to rotate around the first rotating rod 51 as the axis, thereby driving the first rotating rod 51 to rotate, and through the first support plate 52, drives the pressure roller 53 to rotate around the first rotating rod 51 as the axis and presses the old film to be replaced close to the new film.

[0034] At the same time, the second electric push rod 63 drives the second connecting plate 64 to rotate around the second rotating rod 54 through the extension and retraction of the output end, thereby driving the second rotating rod 54 to rotate. The second support plate 55 drives the cutter 56 to rotate around the second rotating rod 54 and cut the old film to be replaced.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
