Description

Technical Field

[0001] This utility model relates to the field of edge trimming equipment technology, specifically an edge trimming device for printing and packaging. Background Technology

[0002] After the printed materials are bound, the bleed area (i.e. the 3 mm edge reserved in the design) needs to be removed by cutting to ensure that the finished product is dimensionally accurate and the edges are neat in order to meet the requirements of process standards and aesthetics.

[0003] Currently, when cutting printed paper, it is usually necessary to place the area to be cut close to the cutter so that the cutter can be used to trim the edges of the printed paper. When multiple edges of the printed paper need to be trimmed, the printed paper needs to be rotated manually to trim the remaining edges. During this process, stacked papers are easily disordered due to handling and rotation, which affects the subsequent trimming effect and is inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide an edge trimming device for printing and packaging, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a trimming device for printing and packaging, comprising a base plate, a cutter movably mounted above the base plate, a drop groove provided on the upper part of the base plate below the cutter, a cutting plate mounted on the upper part of the base plate on one side of the drop groove, a movable plate movably mounted on one side of the cutting plate, a rotary motor mounted at the bottom of the movable plate, a rotating shaft mounted at the output end of the rotary motor, a placement plate mounted on the upper part of the rotating shaft, a fixed frame mounted on the upper part of the movable plate in front of the placement plate, a pressure plate movably mounted on the fixed frame, a processor mounted at one end of the fixed frame, and a limit plate placed on the upper part of the base plate on one side of the placement plate.

[0006] Preferably, a slide rail is installed on the front and rear parts of the upper part of the bottom plate on one side of the cutting plate, and a slider is slidably installed on both slide rails. The moving plate is installed on the upper part of the two sliders.

[0007] Preferably, the upper end of the fixing frame is threadedly connected to an adjusting screw through a screw hole, and the pressure plate is rotatably mounted on the lower end of the adjusting screw through a bearing component.

[0008] Preferably, an electromagnet is installed on the upper end of the base plate between the two slide rails via a groove, and a positioning block is movably installed on one end of the limiting plate above the electromagnet.

[0009] Preferably, a fixing plate is installed at one end of the limiting plate above the electromagnet, a spring is installed at the lower end of the fixing plate, the positioning block is installed at the lower end of the spring, a guide tube is sleeved on the surface of the positioning block, and the guide tube is connected to the limiting plate.

[0010] Preferably, a collection frame is placed below the drop trough, and a moving trough is provided on the upper part of the base plate below the rotating motor.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This edge trimming equipment for printing and packaging uses a placement plate mounted on a rotating shaft of a rotary motor. The control program inside the processor controls the rotary motor to rotate the placement plate by a specified angle, which facilitates the change of the trimming direction of the printing paper. The printing paper can be turned without picking it up, effectively avoiding the misalignment of the printing paper.

[0020] like Figures 1 to 3 As shown, the edge trimming device for printing and packaging in this embodiment includes a base plate 1. A cutter 2 is movably mounted on the top of the base plate 1. The cutter 2 is driven by a hydraulic device. The cutter 2 is a known prior art and will not be described in detail. A drop groove 3 is provided on the upper end of the base plate 1 below the cutter 2. The drop groove 3 is used to drop paper scraps that fall during edge trimming, preventing the paper scraps from accumulating. A cutting plate 4 is installed on the upper end of the base plate 1 on one side of the drop groove 3. The cutting plate 4 and the cutter 2 work together to achieve neat edge trimming of the printed paper. A movable plate 5 is movably mounted on one side of the cutting plate 4. The movable plate 5 can move to facilitate moving the paper towards the cutter 2. A rotary motor 6 is installed at the bottom of the movable plate 5. A rotating shaft 7 is installed at the output end of the rotary motor 6. A placement plate 8 is installed on the upper end of the rotating shaft 7. A fixed frame 9 is installed on the upper end of the movable plate 5 in front of the placement plate 8. A movable part is mounted on the fixed frame 9. The pressure plate 10 and the fixing frame 9 are equipped with a processor 11 at one end. The paper is pressed onto the placement plate 8 by the pressure plate 10. The rotary motor 6 can drive the placement plate 8 and the paper above it to rotate through the rotating shaft 7, so as to change the direction of the paper cutting edge. The rotary motor 6 is a stepper motor, and the control system inside the processor 11 gives the corresponding number of pulses to realize that the rotary motor 6 drives the placement plate 8 to rotate by a specified angle. The rotary motor 6 drives the placement plate 8 to rotate by 90° each time. As for how to control the rotary motor 6 to rotate by a specified angle each time, it is known existing technology, so it will not be described in detail. The rotary motor 6 has a locking function and cannot rotate on its own. A limit plate 12 is placed on the upper end of the bottom plate 1 on one side of the placement plate 8. The limit plate 12 is used to limit the printing paper on the placement plate 8 at the other end to prevent the paper from shifting during the cutting edge.

[0021] Specifically, slide rails 13 are installed on the front and rear of the upper part of the base plate 1 on one side of the cutting plate 4. Slider 14 is slidably installed on both slide rails 13. The moving plate 5 is installed on the upper part of the two sliders 14. When the moving plate 5 moves, the moving plate 5 drives the slider 14 to move inside the slide rail 13, which plays a guiding role in the movement of the moving plate 5.

[0022] Furthermore, the upper end of the fixing frame 9 is threadedly connected to an adjusting screw 15 through a screw hole, and the pressure plate 10 is rotatably mounted on the lower end of the adjusting screw 15 through a bearing component. By rotating the adjusting screw 15, the adjusting screw 15 can drive the pressure plate 10 to move downward, so that the pressure plate 10 can press the stacked papers.

[0023] Furthermore, an electromagnet 16 is installed on the upper end of the base plate 1 between the two slide rails 13 via a groove. A positioning block 17 is movably installed on one end of the limiting plate 12 above the electromagnet 16. When the limiting plate 12 is needed to limit the paper, the electromagnet 16 attracts the positioning block 17 to achieve positioning and fixing of the limiting plate 12.

[0024] Furthermore, a fixing plate 18 is installed on one end of the limiting plate 12 above the electromagnet 16. A spring spring 19 is installed at the lower end of the fixing plate 18. A positioning block 17 is installed at the lower end of the spring spring 19. A guide tube 20 is sleeved on the surface of the positioning block 17. The guide tube 20 is connected to the limiting plate 12. When the electromagnet 16 attracts the positioning block 17, the positioning block 17 contacts the surface of the electromagnet 16. The positioning block 17 stretches the spring spring 19. After the electromagnet 16 is de-energized, the spring spring 19 drives the positioning block 17 to return to its original position, so that the positioning block 17 is located inside the guide tube 20. The guide tube 20 plays a guiding role in the movement of the positioning block 17.

[0025] Furthermore, a collection box 21 is placed below the drop trough 3. The collection box 21 is used to collect and place the paper scraps after cutting. A moving groove 22 is provided on the upper end of the base plate 1 below the rotary motor 6. The setting of the moving groove 22 provides space for the movement of the rotary motor 6 on the moving plate 5.

[0026] The usage method of this embodiment is as follows: First, place the printing paper on the placement plate 8, and rotate the adjusting screw 15 to move the pressure plate 10 downwards. Use the pressure plate 10 to press the paper on the placement plate 8. Then, manually push the moving plate 5. The moving plate 5 moves within the slide rail 13 via the slider 14, causing the printing paper on the placement plate 8 above the moving plate 5 to move towards the cutter 2, positioning the printing paper in the appropriate position. Then, move the limiting plate 12 to limit the printing paper, and control the electromagnet 16 to be energized. The electromagnet 16 attracts the positioning block 17, which stretches the spring spring 19, thus fixing the limiting plate 12. Then, control the cutter 2 to move downwards. 2. The cutting plate 4 works together to trim the edges of the printed paper. The paper scraps that fall off the cutting plate fall into the collection box 21 through the drop groove 3. Then, the electromagnet 16 is de-energized, and the positioning block 17 is restored under the action of the spring spring 19. Then, the moving plate 5 is pulled, and the processor 11 controls the rotary motor 6 to rotate 90° through the control program. During this process, the pressure plate 10 rotates with the printed paper. Then, the untrimmed side of the printed paper is placed on the side of the cutter 2, and the printed paper is brought close to the cutter 2 again to trim the edges. By repeating the above steps, the four sides of the printed paper can be trimmed without picking up and rotating the printed paper. After trimming the four sides of the printed paper, the trimmed printed paper can be removed.

[0027] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
