Abstract
Description
Technical Field
[0001] This utility model belongs to the field of printing equipment, and in particular relates to an edge protection device for an edge trimming machine. Background Technology
[0002] An edge trimming machine, also known as a cutting machine, is a device used to remove excess parts of printed materials after they have been fully bound. In existing fully automatic edge trimming machines, the worktable for placing the printed materials to be cut is designed with a central slot, so that the feeding mechanism and the gripping mechanism can use the central slot to move the stacked printed materials away.
[0003] In the specific operation, when the feeding mechanism pushes the stacked printed materials onto the worktable, the baffles on both sides of the worktable move, using cylinders to push the baffles to the top of the worktable. At this time, when the feeding mechanism pushes the printed materials onto the worktable, they touch the baffles, completing the alignment of the spine of the printed materials. Then, the cylinders on both sides of the worktable move, pushing the side plates towards the worktable, thereby aligning the two sides of the printed materials. After alignment is completed, the pressure plate above the worktable moves, firmly fixing the printed materials onto the worktable. Then, the front cutter and the cutters on both sides move to remove the excess edges of the printed materials.
[0004] While the above structure can complete the trimming action, the cylinder moves quickly and with great force. If the thickness of the stacked printed materials (individual) is thin, it can easily cause some parts to fold, affecting the quality of the finished printed product. Utility Model Content
[0005] This invention addresses the technical problems existing in the alignment mechanism of existing edge trimming machines by proposing an edge-prevention device for edge trimming machines that is reasonably designed, simple in structure, easy to process, and can effectively avoid folding problems during the alignment process.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides an edge-prevention device for an edge-cutting machine, including a worktable and push cylinders disposed on both sides of the worktable. The power end of the push cylinder is connected to a side plate. A slot is provided in the middle of the worktable, and a baffle is provided at the rear end of the worktable. A pressure plate is provided above the worktable, and the pressure plate is lifted and lowered on the worktable. Buffer boxes are also provided on both sides of the worktable. A buffer rod is provided in the middle of the side plate, and the buffer rod extends into the buffer box. A limit plate is provided at the end of the buffer rod that extends into the buffer box. A buffer spring is also fitted on the buffer rod, and the buffer spring is disposed between the limit plate and the buffer box. The push cylinder is disposed on one side of the buffer box.
[0007] Preferably, the bottom of the workbench is also provided with a 90° tilting cylinder, which is located on both sides of the slot hole. The workbench is provided with a through hole for tilting the baffle, and the bottom of the baffle is connected to the tilting end of the 90° tilting cylinder.
[0008] Preferably, the baffle is arranged in an inverted U-shape.
[0009] Preferably, an auxiliary pressure plate is provided at the bottom of the pressure plate, and the area of the auxiliary pressure plate is the same as the area of the printed material after the edge is cut.
[0010] Preferably, the auxiliary pressure plate is made of wood.
[0011] Preferably, the top edge of the auxiliary pressure plate is chamfered.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. This utility model provides an edge protection device for an edge trimming machine. By setting up a buffer box and a buffer rod, the reverse force generated by the spring dampens the push of the push cylinder, so that the side plate will not collide with the printed material quickly, thereby avoiding the occurrence of folding. At the same time, this utility model can be improved on the existing basis and is suitable for large-scale promotion and use. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0021] Example 1, such as Figures 1-3 As shown, this embodiment aims to solve the technical problem of folding caused by the alignment and anti-edge mechanism of existing edge trimming machines when a single printed material is thin. To this end, the anti-edge device for edge trimming machines provided in this embodiment includes a worktable 1 and push cylinders 3 arranged on both sides of the worktable 1. In the prior art, the worktable 1 is actually composed of two flat plates arranged on the left and right. Thus, the gap between the two flat plates is the slot 11 referred to in this embodiment. A connecting plate is provided on the side plate of the flat plate away from the slot 11. The connecting plate has two functions: one is to support the flat plate and ensure the position of the flat plate, and the other purpose is to prevent the edge strips cut off on both sides from entering the bottom of the flat plate.
[0022] The main purpose of the pushing cylinder 3 is to push the side plate 2. For this purpose, the side plate 2 is connected to the power end of the pushing cylinder 3, and a baffle 6 is provided at the rear end of the worktable 1. A pressure plate 7 is provided above the worktable 1. The pressure plate 7 is generally raised and lowered on the worktable 1 by a cylinder. The above structure is a common existing structure, so it will not be described in detail in this embodiment.
[0023] Considering that the main purpose of using a cylinder is its rapid response, and that rapid action inevitably leads to impacts from the side plate 2 on the printed material, while a structure using a motor and lead screw would result in slower action and restrict production efficiency, this embodiment also includes buffer boxes 4 on both sides of the worktable 1. The buffer boxes 4 are rectangular boxes, with a buffer rod 41 located in the middle of the side plate 2. The buffer rod 41 extends into the buffer box 4, and a limit plate 42 is provided at one end of the buffer rod 41 that extends into the buffer box 4. A buffer spring 43 is also fitted onto the buffer rod 41, positioned between the limit plate 42 and the buffer box 4. Simultaneously, a push cylinder 3 is located on one side of the buffer box 4. Thus, the action of the push cylinder 3 also compresses the buffer spring 43. During the compression of the buffer spring 43, the reaction force of the buffer spring 43 prevents the push cylinder 3 from generating excessive impact force, thereby avoiding page folding.
[0024] Considering that the existing baffle 6 is also pushed by the side cylinder of the worktable 1, this structure may push the printed material (due to sensor malfunction). Therefore, to avoid this situation, in this embodiment, a 90° tilting cylinder 5 is also provided at the bottom of the worktable 1. The 90° tilting cylinder 5 is located on both sides of the slot 11, and the worktable 1 is provided with a through hole 12 for tilting the baffle 6. The bottom of the baffle 6 is connected to the tilting end of the 90° tilting cylinder 5. In this way, by controlling the baffle 6 by tilting, even if the sensor fails, the spine of the pushed printed material can be flattened without pushing the printed material away.
[0025] To prevent the baffle 6 from interfering with the pushing mechanism in the event of sensor failure, in this embodiment, the baffle 6 is arranged in an inverted U-shape.
[0026] Considering that the existing pressure plate 7 is mainly a metal plate, it needs to ensure the fixation of the printed matter, so its downward pressure is relatively large. However, when the individual printed matter is thin, it will cause indentation on the top printed matter. Therefore, an auxiliary pressure plate 8 is set at the bottom of the pressure plate 7. The area of the auxiliary pressure plate 8 is the same as the area of the printed matter after the edge is cut.
[0027] To prevent the auxiliary pressure plate 8 from potentially affecting the cutter, in this embodiment, the top corners of the auxiliary pressure plate 8 are chamfered. This chamfer also serves a guiding function, preventing any impact on the cutter.
[0028] Meanwhile, the auxiliary pressure plate 8 is made of wood. This makes the material readily available, and the elasticity of wood effectively prevents indentations.
[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
