Description

Technical Field

[0001] This utility model relates to the field of book processing equipment technology, and more specifically, it relates to a cutting unit in a book cutting device. Background Technology

[0002] In the production and processing of books, cutting is one of the key processes. Its purpose is to trim the edges of the book neatly so that it meets the predetermined size specifications, thereby improving the overall appearance quality of the book. Precise cutting can ensure that the page edges of the book are flat and the size is consistent.

[0003] For example, the patent announcement number CN219685733U discloses a book trimming device, which includes a worktable and a pressing device. The pressing device includes a frame and a hydraulic cylinder fixedly connected to the frame. The frame is equipped with a cutting device, which includes guide posts placed on both sides of the frame and movable parts movably connected to the guide posts. The output end of the hydraulic cylinder is connected to the movable parts. The cutting device is driven to move downward by the hydraulic cylinder, so that the cutting component forms a downward force through the first spring, so that the plate moves downward through the second spring and makes pressure contact with the book. At the same time, the cutting component also moves downward to perform the trimming operation on the book. After the trimming is completed, the paper scraps fall into the tank.

[0004] In the above-mentioned case, when the book needs to be cut multiple times at equal intervals, the device can only drive the cutting part to cut the book once. After that, the cutting part needs to be manually aligned with the cutting part, and the cutting part needs to be driven to move towards the book multiple times to cut. This process is cumbersome, reduces production efficiency, and increases labor and time costs. Furthermore, manual alignment of the cutting position is prone to errors, resulting in low cutting efficiency and affecting the overall quality of the book. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cutting unit in a book cutting device that reduces labor and time costs and improves cutting efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A cutting unit in a book cutting device includes a frame, a cylinder mounted on the frame, and a fixed plate fixed to the frame. The cylinder is fixed to the frame, and its output end is connected to one side of the fixed plate. A rod is mounted on the other side of the fixed plate and is fixedly connected to the fixed plate. The machine frame is also equipped with several tool holders, which are slidably connected to the machine frame. The tool holder is placed on one side of the shaft. Both the tool holder and the rod body are equipped with rotating rods, one end of which is fixed to both the tool holder and the rod body. Connecting parts are provided between adjacent rotating rods. The connecting components include a first positioning shaft, a second positioning shaft, a third positioning shaft, and a fourth positioning shaft. The first positioning axis, the second positioning axis, the third positioning axis, and the fourth positioning axis surround each other. One end of the first positioning shaft, one end of the second positioning shaft, one end of the third positioning shaft, and one end of the fourth positioning shaft are all hinged to the rotating rod. The other end of the first positioning shaft is hinged to the other end of the second positioning shaft. The other end of the third positioning axis is hinged to the other end of the fourth positioning axis.

[0007] The present invention is further configured such that: both the tool holder and the rod body are provided with a cutting head, and the cutting head is detachably connected to the tool holder and the rod body respectively.

[0008] The present invention is further configured such that: both the cutter bar and the rod body are provided with slots, one end of the cutter head extends into the slot and is connected to the slot, and the cutter bar and the cutter head are fixed together with screws as are the rod body and the cutter head.

[0009] The present invention is further configured such that: a guide rod is provided on the frame, and a directional sleeve is provided on one of the tool bars, the directional sleeve is sleeved on the guide rod and slides with the guide rod.

[0010] By adopting the above technical solution, the beneficial effects of this utility model are as follows: The distance between the cutter bars is adjusted equidistantly by using a connector. When the rod moves, the connector drives one of the cutter bars to move, which in turn drives the other cutter bars to move in turn. This achieves equidistant adjustment of the distance between the rod and the cutter bars, as well as between adjacent cutter bars, greatly improving production efficiency, reducing manual operation and time costs, and thus lowering labor and time costs while improving cutting efficiency. The cooperation between the guide rod and the directional sleeve ensures the smoothness of the cutter bar movement. Together with the connector, it can effectively improve cutting accuracy. The cutter head adopts a detachable connection method, and different sizes of cutter heads can be replaced according to different cutting needs. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0015] like Figures 1 to 2 As shown, the cutting unit of the book cutting equipment includes a frame 1, on which a cylinder 2 and a fixed plate 3 fixed to the frame 1 are installed. The cylinder 2 is fixed to the frame 1, and its output end is connected to one side of the fixed plate 3. Through the extension and retraction of the cylinder 2, power is provided to the cutting unit, driving the fixed plate 3 to move up and down.

[0016] A rod 4 is installed on the other side of the fixed plate 3, and four cutter bars 5 are installed on the rod 4. These cutter bars 5 are placed on one side of the rod 4. A guide rod 15 is installed on the frame 1. One of the cutter bars 5 is equipped with a directional sleeve 16. The directional sleeve 16 is fitted onto the guide rod 15 and slides with the guide rod 15. The cooperation between the guide rod 15 and the directional sleeve 16 provides guidance for the movement of the cutter bar 5, ensuring the stability and straightness of the cutter bar 5 during the movement, and further improving the cutting accuracy.

[0017] Rotating rods 6 are installed on both the tool holder 5 and the rod body 4. One end of the rotating rod 6 is fixed to the tool holder 5 and the rod body 4 respectively. Connecting parts 7 are installed between adjacent rotating rods 6. The connecting parts 7 include a first positioning shaft 8, a second positioning shaft 9, a third positioning shaft 10 and a fourth positioning shaft 11, which are arranged in a circle.

[0018] One end of the first positioning shaft 8, one end of the second positioning shaft 9, one end of the third positioning shaft 10, and one end of the fourth positioning shaft 11 are all hinged to the rotating rod 6. The other end of the first positioning shaft 8 is hinged to the other end of the second positioning shaft 9, and the other end of the third positioning shaft 10 is hinged to the other end of the fourth positioning shaft 11.

[0019] The connection structure, consisting of a first positioning shaft 8, a second positioning shaft 9, a third positioning shaft 10, and a fourth positioning shaft 11, allows one end of the second positioning shaft 9 and one end of the fourth positioning shaft 11 to rotate around the rotating rod 6 on the rod 4 when the rod 4 moves. The second positioning shaft 9 drives the first positioning shaft 8 to rotate, and the fourth positioning shaft 11 drives the third positioning shaft 10 to rotate. At this time, the first positioning shaft 8 and the third positioning shaft 10 drive the rotating rod 6 on the cutter bar 5 to rotate, and then drive the other cutter bars 5 to move in sequence, so as to realize the equidistant adjustment of the distance between the rod body 4 and the cutter bar 5 and the adjacent cutter bars 5, thereby meeting the needs of multiple equidistant cutting of books.

[0020] Both the cutter shank 5 and the rod body 4 are equipped with cutter heads 12. Both the cutter shank 5 and the rod body 4 have slots 13. One end of the cutter head 12 extends into and connects to the slot 13. The cutter shank 5 and the cutter head 12 are fixed together with each other and with the rod body 4 and the cutter head 12 with screws 14. By rotating the screws 14 with a tool, the screws 14 can be removed from the cutter shank 5 and the cutter head 12. This detachable connection method has a simple structure, facilitates quick replacement of different sized cutter heads 12, and reduces maintenance and time costs.

[0021] Working principle: First, based on the book's specifications and cutting requirements, a suitable cutter head 12 is selected and installed on the cutter bar 5 and the rod body 4. When it is necessary to adjust the distance between adjacent cutter bars 5 and the distance between the cutter bar 5 and the rod body 4, the cylinder 2 is activated. The cylinder 2 pushes the fixed plate 3 to move, and the fixed plate 3 moves the rod body 4. Since the rod body 4 is equipped with a rotating rod 6, and adjacent rotating rods 6 are connected by a connector 7, the connector 7 drives the cutter bar 5 to move. During the movement of the cutter bar 5, the directional sleeve 16 moves along the guide rod 15, providing guidance for the movement of the cutter bar 5, making the movement more stable. At this time, the distance between adjacent cutter bars 5 and the distance between the cutter bar 5 and the rod body 4 are equal. Then, the cutter head 12 cuts the book. After the cutting is completed, if it is necessary to adjust the distance between adjacent cutter bars 5 and the distance between the cutter bar 5 and the rod body 4 again, the cylinder 2 retracts to make the adjustment.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
