Description

Technical Field

[0001] This utility model relates to the field of book printing and processing, and in particular to a scrap material cutting and collecting device for book printing and processing. Background Technology

[0002] During the printing and binding process of books, the paper is initially larger than the finished size to facilitate printing. After printing, the books are trimmed, which usually involves placing them on a book trimmer to remove excess material from the edges. To facilitate the unified recycling of the trimmed scraps, most book trimmers now include a scrap collection device. This device consists of a discharge port or trough on one or three sides of the book support platform. The scrap material falls through the discharge port or trough into a collection box below. For example, the existing patent CN213226502U describes a book trimming device with a scrap recycling structure, which includes a base and an operating table on the base for placing the book. The operating table has through holes on the three edges of the book to be trimmed for the scrap material to pass through. The base has a cavity below the operating table, which contains a scrap recycling mechanism. The base also has a trimming mechanism for pressing and cutting the book. However, when using this device, in order to facilitate the cut waste material falling down through the through hole, the edge of the book needs to extend beyond the edge of the operating table (i.e., the support table that supports the book) and be above the through hole. As a result, the bottom of the book cannot be fully supported. When cutting, the lack of support at the edge will cause the paper edge to deform under the pressure of the cutter, ultimately leading to uneven cut edges. Utility Model Content

[0003] The purpose of this utility model is to provide a scrap cutting and collection device for book printing and processing, which solves the problem mentioned in the background art that the width of the support platform for supporting books is fixed, and when the edge of the book exceeds the edge of the support platform, the edge of the paper is deformed due to force, resulting in uneven cutting edges.

[0034] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] like Figure 1 As shown, this embodiment discloses a scrap material cutting and collection device for book printing and processing, including a workbench 1, a support plate 2 on the workbench 1, and a material discharge port 8 on three sides of the support plate 2. L-shaped closing plates 3 are located on both sides of the support plate 2, within the material discharge ports 8. The closing plates 3 are slidably connected to the workbench 1, and are in contact with the three sides of the support plate 2. The closing plates 3 are connected to a drive assembly 4. The drive assembly 4 drives the closing plates 3 to slide, causing the material discharge ports 8 to open or close. A cutting mechanism 5 is located above the support plate 2, and a scraping assembly 6 is located on the cutting mechanism 5. A collection box 7 is located below the support plate 2, fixedly connected to the bottom of the workbench 1, and positioned below the material discharge ports 8. The cutting mechanism 5 trims the edges of the book. After trimming, the drive component 4 moves the closing plate 3 to open the material drop port 8. The trimmed scraps fall into the collection box 7 below. Then, the drive component 4 pushes the closing plate 3 to close, so that the support plate 2 and the closing plate 3 form a complete platform surface again, which can be used for the next trimming operation.

[0036] like Figures 2 to 5As shown, the support plate 2 has first inclined surfaces 2-1 on both sides, forming an inverted V-shape. The closing plate 3 has a matching second inclined surface 3-1. The drive assembly 4 includes a housing 4-1, which is fixedly mounted on the workbench 1. A first cylinder 4-2 is housed inside the housing 4-1, with its movable end connected to the side of the closing plate 3 opposite to the support plate 2. When the first cylinder 4-2 pushes the closing plate 3 to close, the first inclined surface 2-1 overlaps with the second inclined surface 3-1, closing the material discharge port 8. When the first cylinder 4-2 pulls the closing plate 3 back, the first inclined surface 2-1 separates from the second inclined surface 3-1, opening the material discharge port 8.

[0037] In this embodiment, the bottom of the collection box 7 is provided with an openable bottom plate to facilitate the discharge of collected scraps. Simply put, the bottom of the collection box 7 is hinged to the bottom plate, and the opposite side of the hinged edge on the bottom plate is connected to the bottom of the collection box 7 in an openable manner through a locking assembly.

[0038] like Figures 5 to 7 As shown, grooves 8-1 are provided on both sides of the front and rear sides of the material discharge port 8, and matching slide rails 3-2 are provided on the closing plate 3. The slide rails 3-2 and the grooves 8-1 are slidably connected and cooperate, and the grooves 8-1 and the slide rails 3-2 play a guiding role for the closing plate 3.

[0039] The support plate 2 is equipped with a detachable back baffle 9. Specifically, the support plate 2 has a first long groove 2-2 extending into the workbench 1. A screw 9-1 is located at the bottom of the back baffle 9. The screw 9-1 passes through the first long groove 2-2 and is secured to the workbench 1 with a nut. By loosening the nut and adjusting the position of the screw 9-1 in the first long groove 2-2, the back baffle 9 can be moved back and forth. Multiple first long grooves 2-2 and screws 9-1 can be provided; in this embodiment, only one is provided. In this embodiment, the first long groove 2-2 is rectangular, and the screw 9-1 has a corresponding sliding rectangular portion to prevent the back baffle 9 from rotating during movement. The closing plate 3 has multiple threaded holes 3-3 arranged in a row. Side baffles 10 are bolted into the threaded holes 3-3. The positions of the left and right side baffles 10 can be adjusted using the threaded holes 3-3 to accommodate books of different sizes. With the two closing plates 3 closed, the back baffle 9 and the two side baffles 10 limit the three sides of the book. The book is placed between the back baffle 9 and the two side baffles 10, and the cutting mechanism 5 is activated to perform the trimming operation. The back baffle 9 and the two side baffles 10 are set according to the required trimming dimensions to avoid trimming offset errors caused by the book's misalignment with the cutting mechanism 5.

[0040] In this embodiment, the back baffle 9 is provided with second sliding grooves 9-2 on both sides, and the side baffle 10 is provided with a slider 10-1 at one end, which slides in cooperation with the second sliding grooves 9-2. When the closing plate 3 is opened, it will drive the side baffle 10 to move, thereby triggering the scraping assembly 6.

[0041] like Figure 8 As shown, the cutting mechanism 5 includes a three-sided cutter 5-1, which is detachably connected to the push plate 5-2 by means of a bolt assembly. The push plate 5-2 is connected to the movable end of the second cylinder 5-3, which is fixedly mounted on the bracket 5-4. The bracket 5-4 is mounted on the worktable 1.

[0042] The scraping assembly 6 includes a scraping frame 6-1, which is U-shaped and closely attached to the three-sided cutter 5-1. The scraping frame 6-1 is fixedly connected to the bottom end of the spring telescopic rod 6-2, and the top end of the spring telescopic rod 6-2 is fixedly connected to the push plate 5-2. A stop rod 6-3 is fixedly connected to the scraping frame 6-1, and the stop rod 6-3 contacts and engages with the side baffle 10. With the closing plate 3 closed (i.e., the material outlet 8 closed), the back baffle 9 and the two side baffles 10 limit the books. The second cylinder 5-3 is activated, pushing the top plate 5-2 down and causing the three-sided cutter 5-1 to move down for edge cutting. During the downward movement, the stop rod 6-3 falls on the side baffle 10 and is prevented from moving down. At this time, the scraper frame 6-1 stops moving down, and the spring telescopic rod 6-2 is compressed until the edge cutting is completed. The three-sided cutter 5-1 remains stationary. After the edge cutting is completed, the first cylinder 4-2 is activated to open the closing plate 3 and move the side baffle 10 away. At this time, the stop rod 6-3 is no longer obstructed, and the spring telescopic rod 6-2 returns to its original position under the action of elasticity, pushing the scraper frame 6-1 down. At the same time, the scraper frame 6-1 scrapes off the debris stuck to the blade surface of the three-sided cutter 5-1. The scraps and debris fall from the material outlet 8 into the collection box 7.

[0043] It should be noted that in some embodiments, a pressure plate can be added below the push plate 5-2 to press the center of the top surface of the book. Specifically, multiple thicker spring telescopic rods 6-2 are added below the push plate 5-2. The top ends of the spring telescopic rods 6-2 are connected to the bottom of the push plate 5-2, and the bottom ends of the spring telescopic rods 6-2 are fixedly connected to a flat pressure plate. Both the spring telescopic rods 6-2 and the pressure plate are located inside the three-sided cutter 5-1. When the push plate 5-2 moves downward, it drives the spring telescopic rods 6-2 and the pressure plate downward until the pressure plate contacts the top surface of the book. The push plate 5-2 continues to move downward, compressing the spring telescopic rods 6-2, and the pressure plate presses tightly against the top surface of the book. This part is a prior art and not part of the main content of this technical solution; therefore, it is only briefly introduced here and will not be elaborated further.

[0044] like Figure 11The diagram shows the structure of the spring telescopic rod 6-2. The spring telescopic rod 6-2 includes a sleeve containing a spring. A slidingly connected rod is located on the top wall of the sleeve. The bottom end of the rod is confined within the sleeve and abuts against one end of the spring. The bottom end of the sleeve is fixedly connected to the scraper frame 6-1, and the top end of the rod is fixedly connected to the bottom surface of the push plate 5-2.

[0045] like Figures 1 to 10 As shown, the working process of this utility model is as follows:

[0046] First, the back baffle 9 and the two side baffles 10 are set up according to the required book size. When placing the books, ensure that one side of the book rests on the back baffle 9, and the other two sides of the books rest on the side baffles 10. Three sides of the books should be within the L-shaped area of ​​the closing plate 3 (i.e., the material drop area 8). Simultaneously, the three-sided cutter 5-1 is also positioned directly above this area. In this state, the support plate 2 supports most of the inner side of the book, and the closing plate 3 supports the periphery of the book, facilitating the downward cutting of the three-sided cutter 5-1. Next, the second cylinder 5-3 is activated, driving the three-sided cutter 5-1 downwards for edge cutting. During the downward movement, the stop rod 6-3 falls onto the side baffle 10 and is prevented from moving further. At this time, the scraper frame 6-1 stops moving downwards, and the spring telescopic rod 6-2 is compressed until the edge cutting is complete. At this point, the three-sided cutter 5-1 remains stationary. After the cutting is completed, the first cylinder 4-2 is activated. The first cylinder 4-2 moves the two closing plates 3, opening the material outlet 8. The cut-off scraps, no longer supported by the closing plates 3, fall directly into the collection box 7. Simultaneously, the closing plates 3 move, causing the side baffle 10 to move away. The baffle 6-3 loses its obstruction, and the spring telescopic rod 6-2 returns to its original position under elasticity, pushing the scraper frame 6-1 downwards. At the same time, the scraper frame 6-1 scrapes off the debris adhering to the blade of the three-sided cutter 5-1, which falls into the collection box 7. After scraping is complete, the second cylinder 5-3 is deactivated, the three-sided cutter 5-1 is retracted, the book is removed, and the first cylinder 4-2 is deactivated again, closing the two closing plates 3 and shutting off the material outlet 8, ready for the next cutting operation.

[0047] After the cut-off scraps and debris fall into the collection box 7, if there are too many scraps and debris, the bottom plate of the collection box 7 can be opened to remove them for unified processing.

[0048] This novel invention uses a closing plate 3 that, when closed, works in conjunction with a support plate 2 to support the book. When the closing plate 3 opens, it creates a discharge port 8, allowing the cut scraps to fall off automatically. It is suitable for any book larger than the support plate 2. When changing to books of different sizes, only the positions of the back baffle 9 and the two side baffles 10, the compatible three-sided cutter 5-1, and the corresponding scraper assembly 6 need to be adjusted. This achieves the beneficial effect of adapting a single workbench to the cutting of books of different sizes.

[0049] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
