Description

Technical Field

[0001] The utility model relates to the field of book printing, and particularly relates to a hemming device for book printing. Background Art

[0002] Printing is a technology that transfers the original content such as text, pictures, and photos to the surfaces of materials such as paper, textiles, and leather through processes such as plate making, ink application, and pressing, and batch-replicates the original content. In simple terms, printing is a process technology that uses a printing plate or other means to transfer the graphic and text information on the original to the printing substrate, and can also be understood as a replication process that transfers the colorant material to the printing substrate using an analog or digital image carrier.

[0003] However, in the prior art, the hemming force of traditional equipment is usually fixed. Therefore, when the production batches are different and the thicknesses of the books are different, the fixed hemming force cannot perform the hemming work on books with different thicknesses, thus affecting the subsequent work. In addition, when hemming a book, the hemming position of the book may be inaccurate due to the movement of the book. Content of the Utility Model

A rotating ring is slidably connected to the inner wall of the fixed ring through a sliding ball, and the top of the sliding ball is fixedly connected to the bottom of the rotating ring. The sliding balls are annularly arranged along the central axis of the rotating ring. A top block is fixedly connected to the outer wall of the rotating ring, and the top blocks are annularly arranged along the central axis of the rotating ring. A fixing plate is fixedly connected to the outer wall of the fixed ring, and a plug plate is slidably connected to the top of the fixing plate.

[0037] The adjusting mechanism 6 includes a fixed ring 61. The outer wall of the fixed ring 61 is fixedly connected with a limiting ring 64. The inner wall of the fixed ring 61 is slidably connected with a rotating ring 62 through a sliding ball 68, and the top of the sliding ball 68 is fixedly connected with the bottom of the rotating ring 62. The outer wall of the rotating ring 62 is fixedly connected with a top block 63, and the top blocks 63 are arranged in a circular array along the central axis of the rotating ring 62. The outer wall of the fixed ring 61 is fixedly connected with a fixing plate 66. The top of the fixing plate 66 is slidably connected with an inserting plate 65. The position of the inserting plate 65 is restricted by the top block 63. The bottom of the inserting plate 65 is fixedly connected with an elastic plate 67. One side of the elastic plate 67 away from the inserting plate 65 is fixedly connected with the outer wall of the fixing plate 66. The outer wall of the inserting plate 65 is slidably connected with the outer wall of the top block 63. The outer wall of the limiting ring 64 is slidably connected with the inner wall of the fixed cylinder 52. The outer wall of the inserting plate 65 is slidably connected with the inner wall of the fixed cylinder 52 through a limiting groove 56, and the limiting groove 56 is opened in the wall of the fixed cylinder 52. The top of the limiting ring 64 is in contact with the bottom of the sliding rod 55.

[0038] The preloading mechanism 4 includes a preloading plate 45. Both sides of the top of the preloading plate 45 are fixedly connected with connecting plates 41. The inner wall of the top of the connecting plate 41 is fixedly connected with a spring 42. The spring 42 enables the connecting plate 41 to have a downward sliding force. The outer wall of the connecting plate 41 is slidably connected with a limiting plate 43 through a positioning post 44, and the outer wall of the positioning post 44 is fixedly connected with the outer wall of the connecting plate 41. The outer wall of the connecting plate 41 is slidably connected with the inner wall of the frame 1. The top of the frame 1 is fixedly connected with the bottom of the spring 42. The outer wall of the limiting plate 43 is inserted into the inner wall of the folded edge plate 51. The bottom of the folded edge plate 51 is in contact with the top of the preloading plate 45.

[0039] Working principle:

[0040] When in use, first place the frame 1 on the ground. After the position of the frame 1 is placed stably, place the book to be folded on the working plate 3. Then pull the limiting plates 43 on both sides of the preloading mechanism 4, so that the preloading plate 45 slides downward and presses on the book, thereby initially fixing the book and preventing the book from shifting in position during the folding process. After the position of the book is initially fixed, start the hydraulic unit 2. The telescopic rod in the hydraulic unit 2 drives the folding edge mechanism 5 to move downward, thereby folding the book. After the book is folded, first insert the limiting plates 43 in the preloading mechanism 4 back into the folded edge plate 51, forcing the preloading plate 45 and the folded edge plate 51 to be connected as a whole. Then start the hydraulic unit 2 again. The hydraulic unit 2 drives the folding edge mechanism 5 to move upward, thereby driving the preloading mechanism 4 to reset upward. When the thickness of the book is different, the corresponding folding edge force should also be adjusted accordingly. Just change the position of the limiting ring 64 through the adjusting mechanism 6, so as to change the downward pressing height of the folded edge plate 51, and then change the folding edge force on the book.

[0041] Before using the preloading mechanism 4, the preloading mechanism 4 should be at the top of the working plate 3 and connected to the hemming plate 51. Therefore, after the book is placed, the limiting plates 43 on both sides of the frame 1 can be slid out of the hemming plate 51 along the positioning posts 44. Square grooves corresponding to the limiting plates 43 are provided on the hemming plate 51. Therefore, after the limiting plates 43 slide out of the square grooves, the locking of the hemming plate 51 to the preloading plate 45 is released. After the spring 42 lacks the stretching of the connecting plate 41, it releases the elastic potential energy, driving the connecting plate 41 to move downward, so that the preloading plate 45 presses on the book.

[0042] After the book is preliminarily positioned by the preloading mechanism 4, then start the hydraulic unit 2, so that the telescopic rod in the hydraulic unit 2 drives the sliding rod 55 to slide downward. During the downward sliding of the sliding rod 55, the sliding rod 55 drives the hemming plate 51 to press on the preloading plate 45 through the top spring 54 first, so as to perform a preliminary hemming on the book. Then, when the sliding rod 55 slides along the fixed cylinder 52 to the positioning ring on the limiting post 53, it drives the hemming plate 51 to perform the hemming work on the book. It should be noted that the positioning ring is the lowest sliding position of the sliding rod 55 in the fixed cylinder 52. After the sliding rod 55 contacts the positioning ring, the hemming plate 51 and the sliding rod 55 move downward synchronously, and the hemming force on the book is the largest. The hemming force of the hemming plate 51 driven by the top spring 54 on the book is smaller than the hemming force through the positioning post 44.

[0043] When it is necessary to adjust the position of the limiting ring 64 through the adjusting mechanism 6, it is necessary to first reset the hemming mechanism 5, and then rotate the rotating ring 62. The rotating ring 62 is connected in the fixed ring 61 through the sliding ball 68, so that the rotating ring 62 can rotate freely on the fixed ring 61. Through the rotation of the rotating ring 62, the insertion plate 65 is located between the top blocks 63, so that the top blocks 63 do not press on the insertion plate 65. After the insertion plate 65 lacks the restriction of the top blocks 63, because one end of the elastic plate 67 is fixed on the fixed plate 66, the elastic plate 67 cannot push the side of the fixed plate 66, and can only push the insertion plate 65 to slide away from the fixed plate 66, so that the insertion plate 65 slides out of the limiting groove 56 on the fixed cylinder 52, and the locking of the fixed ring 61 is released. Then the fixed ring 61 can be slid up and down, and the limiting ring 64 is driven to move synchronously by the fixed ring 61. After the limiting ring 64 is adjusted to the required position, first keep the position of the limiting ring 64, and then rotate the rotating ring 62 again, so that the top blocks 63 press behind the insertion plate 65, so that the insertion plate 65 coincides and is inserted back into the limiting groove 56, and the elastic plate 67 is compressed synchronously, so that the elastic plate 67 accumulates elastic potential energy.

All other embodiments obtained by those of ordinary skill in the art and related fields based on the embodiments in the present utility model without creative efforts shall fall within the scope of protection of the present utility model.
