Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to a positioning device for trimming the edges of printed books. Background Technology

[0002] After printing, books and brochures need to be trimmed to improve aesthetics, ensure consistent dimensions, and enhance design. Currently, the trimming process involves operators first flattening the stacked brochures and books, then pushing them under a trimming blade for trimming. However, this process often results in unevenness between the books, and the operators' visual inspection for flattening leads to poor precision, thus affecting the trimming result. Utility Model Content

[0003] This utility model provides a positioning device for trimming the edges of printed books, which solves the shortcomings of the prior art and addresses the problem of poor flatness when stacking books, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A positioning device for trimming printed booklets includes a base plate, which has a rectangular structure and multiple support plates on the base plate.

[0006] Two pairs of rectangular tubes are installed on the lower wall of the base plate by screws. The length direction of the rectangular tubes is parallel to the length direction of the base plate. The rectangular tubes have strip holes, and the length direction of the strip holes is parallel to the length direction of the rectangular tubes. Connecting screws are inserted into the strip holes. The upper end of the connecting screws is connected to an inner plate by threads. The inner plate is inserted into the rectangular tube. A concave side plate is installed on the outer end of each pair of inner plates on the same side by screws.

[0007] A concave part is installed on the lower wall of the base plate by screws. The length direction of the concave part is parallel to the width direction of the base plate. A protrusion is formed on the outer end of the concave part. A locking screw is installed on the protrusion. A tightening nut is connected to the upper end of the locking screw by threads. The lower end of the tightening nut is pressed against the upper wall of the protrusion. An extension plate is fitted on the lower end of the locking screw. An elongated hole is opened on the extension plate. The lower end of the locking screw passes through the elongated hole. The end cap of the lower end of the locking screw is close to the lower wall of the extension plate. An end concave plate is installed on the outer end of the extension plate by screws.

[0008] Furthermore, guide strips are formed on both sides of the concave part, and sliding sleeves are respectively fitted on both sides of the concave part. The guide strips pass through the sliding sleeves. A T-shaped moving plate is installed at the lower end of the sliding sleeve by screws. Spreading rods are rotatably provided at both ends of the horizontal section of the T-shaped moving plate. A movable plate is installed on each pair of connecting screws located on the same side. An oblique hole is opened on the movable plate, and the spreading rod passes through the oblique hole.

[0009] Furthermore, one end of the concave part is connected to an inner shaft via a bearing. A vertical guide hole is provided on the vertical section of the T-shaped moving plate, and the inner shaft passes through the vertical guide hole. A rotating block is welded to the lower end of the inner shaft, and a rotating push rod is connected to the rotating block. A rotating protrusion is provided on the inner end of the rotating push rod, and a top wheel is rotatably provided on the other end of the rotating protrusion. A pushing protrusion is provided on the horizontal section of the T-shaped moving plate, and the outer periphery of the top wheel is tangent to the inner wall of the pushing protrusion.

[0010] Furthermore, the rotating block is connected to the rotating push rod by a thread.

[0011] Furthermore, a rotating cap is provided on the outer end of the rotating push rod.

[0012] The advantages of the above technical solution are:

[0013] This invention provides a base plate that facilitates the stacking and support of books, and its levelness is easily controlled, thus improving the edge trimming effect. Furthermore, the concave side plates constrain the glued edges or center seams of the books, ensuring that the other side of the books remains flush. The end concave plates align the two ends of the books simultaneously, and this alignment is further enhanced by moving them inwards at the same time. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0015] Figure 1 A three-dimensional structure of one embodiment is shown. Figure 1 .

[0016] Figure 2 A magnified view of point A is shown.

[0017] Figure 3 A three-dimensional structure of one embodiment is shown. Figure 2 .

[0018] Figure 4 A magnified view of point B is shown. Detailed Implementation

[0019] like Figures 1-4 As shown, a positioning device for trimming the edges of a printed booklet includes a base plate 1, which has a rectangular structure and multiple support plates 10 are provided on the base plate 1.

[0020] Two pairs of rectangular tubes 39 are screwed onto the lower wall of the base plate 1. The length direction of the rectangular tubes 39 is parallel to the length direction of the base plate 1. A strip-shaped hole 40 is formed in each rectangular tube 39, and the length direction of the strip-shaped hole 40 is parallel to the length direction of the rectangular tube 39. A connecting screw 43 passes through the strip-shaped hole 40, and an inner plate 41 is threaded onto the upper end of the connecting screw 43. The inner plate 41 passes through the rectangular tube 39. A concave side plate 42 is screwed onto the outer end of each pair of inner plates 41 on the same side. A concave component 2 is screwed onto the lower wall of the base plate 1. The length direction is parallel to the width direction of the base plate 1. The outer end of the concave part 2 is formed with a protrusion 20. A locking screw 21 is passed through the protrusion 20. The upper end of the locking screw 21 is connected to a tightening nut 22 by thread. The lower end of the tightening nut 22 is pressed against the upper wall of the protrusion 20. The lower end of the locking screw 21 is fitted with an extension plate 24. An elongated hole 25 is opened on the extension plate 24. The lower end of the locking screw 21 passes through the elongated hole 25. The end cap of the lower end of the locking screw 21 is tightly attached to the lower wall of the extension plate 24. An end concave plate 26 is installed on the outer end of the extension plate 24 by screws.

[0021] The position of the end concave plate 26 can be fixed by tightening the top nut 22. Usually, since the size of books in the same batch is the same, its position is only adjusted when the book size changes. The concave side plate 42 mainly serves to align the back of the book. The inner wall of the movable concave side plate 42 limits the two ends of the book, thereby aligning the two ends of the book and improving the trimming effect.

[0022] In this embodiment, the operator first adjusts the position of the end concave plate 26 according to the size of the book. During adjustment, the top nut 22 needs to be loosened first, and then the position of the end concave plate 26 is adjusted as needed. After adjustment, the position of the concave side plate 42 is fixed by tightening the top nut 22. Then, the stacked books are placed on the base plate 1, with the glued edges or center seams of the books pressed against the end concave plate 26. Next, the concave side plate 42 is moved inward to align the two ends of the book, and then the edges are trimmed.

[0023] In some embodiments, guide strips 23 are formed on both sides of the concave member 2, and sliding sleeves 33 are respectively fitted on both sides of the concave member 2. The guide strips 23 pass through the sliding sleeves 33. A T-shaped movable plate 34 is installed at the lower end of the sliding sleeve 33 by screws. Spreading rods 37 are rotatably provided at both ends of the horizontal section of the T-shaped movable plate 34. A movable plate 44 is installed on each pair of connecting screws 43 located on the same side. An oblique hole 45 is opened on the movable plate 44. The oblique hole 45 is inclined, and the end of the oblique hole 45 near the concave member 42 extends outward at an oblique angle. The spreading rods 37 pass through the oblique holes 45. One end of the concave part 2 is connected to an inner shaft via a bearing. A vertical guide hole 35 is provided on the vertical section of the T-shaped moving plate 34. The inner shaft passes through the vertical guide hole 35. A rotating block 3 is welded to the lower end of the inner shaft. A rotating push rod 30 is connected to the rotating block 3. Optionally, the rotating block 3 is threaded to the rotating push rod 30. A rotating cap 9 is provided on the outer end of the rotating push rod 30. The inner end of the rotating push rod 30 is provided with a rotating protrusion 31, and the other end of the rotating protrusion 31 is provided with a top wheel 32. The horizontal section of the T-shaped moving plate 34 is provided with a pushing protrusion 36. The outer periphery of the top wheel 32 is tangent to the inner wall of the pushing protrusion 36. Through the T-shaped moving plate 34 and the oblique hole 45 provided on the moving plate 44, when the T-shaped moving plate 34 moves, the spreading rod 37 on it will act on the oblique hole 45, thereby causing the end concave plates 26 located at both ends to move closer to each other, and causing the inner wall of the end concave plates 26 to be tightly attached to the two ends of the book, thereby making the books stack neatly. In addition, in order to further facilitate the alignment operation of the two ends of the book, a rotating push rod is also provided, so as to facilitate the quick alignment operation of the two ends of the book.

[0024] When aligning the two ends of a book using the components provided in this embodiment, the rotating push rod 30 is first rotated according to the size of the book to adjust the position of the top wheel 32. After adjustment, the operator rotates the rotating push rod 30 around the axial direction of the inner shaft. When the rotating push rod 30 rotates, the top wheel 32 at its inner end acts on the pushing protrusion 36, thereby causing the T-shaped moving plate 34 to move. When the T-shaped moving plate 34 moves, it acts on the inclined hole 45 through the spreading rod 37 on it, thereby causing the moving plate 44 to move inward at the same time. As the moving plate 44 moves, it will drive the concave side plate 42 on it to move closer to the two ends of the book, thereby aligning the two ends of the book.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
