Description

Technical Field

[0001] This utility model belongs to the field of printing equipment technology, specifically relating to a book block flattening machine with adjustable function. Background Technology

[0002] A book block flattening machine is a post-printing processing device used to flatten book blocks, and it has functions such as flattening, pressing, and shaping. Depending on the method of applying pressure, book block flattening machines can be divided into two types: mechanical and hydraulic. Book block flattening machines are commonly used for flattening, bundling, and backing pressure maintenance of printed paper products (such as books, magazines, and exercise books).

[0003] Patent CN209320520U discloses "a book block flattening machine, relating to the field of printing technology. Because operators often need to place their hands between the pressing table and the lifting pressure plate when operating existing flattening machines, there is a safety hazard. This solution includes a base, with the upper side of the base serving as the pressing table. A support rod is fixed to the pressing table, and a top plate is fixed to the upper end of the support rod. A lifting pressure plate is located between the top plate and the pressing table, and a hydraulic cylinder is installed on the top plate. The space between the lifting pressure plate and the pressing table is the pressing area. An inlet / outlet bookshelf and a pusher bookshelf are respectively located on both sides of the base. A conveyor belt is installed on the inlet / outlet bookshelf. A pusher component is installed on the pusher bookshelf to push the book blocks in the pressing area back onto the conveyor belt. With this design, the operator's hands do not need to be placed inside the pressing area, thus reducing the safety hazard."

[0004] Although the pusher plate of the above-mentioned existing technology can push the flattened book block to other areas, since the book blocks are usually stacked when flattened, the weight of the stacked book blocks will be entirely applied to the bottom book block. This results in a large friction between the bottom book block and the water pressure platform when pushing the book block, making it extremely difficult to push the bottom book block. It is also easy to tilt and collapse. Furthermore, due to the excessive friction, the surface of the bottom book block is prone to wear and cracking when pushing. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide a book block flattening machine with adjustable function in order to solve the above problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A book block flattening machine with adjustable function includes a machine body, a flattening mechanism installed on the top of the machine body, and a book pushing mechanism installed on one side of the machine body for pushing the book block after the top of the machine body is flattened. The top of the machine body has several through holes, and several rollers are movably installed in each of the through holes of the machine body for raising the book block to assist its movement when pushing the book. A base plate is slidably connected to the bottom of the rollers in the machine body.

[0008] The book pushing mechanism is provided with an adjustment mechanism for adjusting the height of the rollers on one side. The adjustment mechanism includes an adjustment plate located on one side of the book pushing mechanism and abutting against the base plate. A guide slope is provided between the adjustment plate and the base plate for pressing and raising the base plate by guiding the adjustment plate as it moves into the machine body.

[0009] As a further optimization of this utility model, a plurality of support rods are fixedly provided at the top edge of the machine body, and a top plate is fixedly provided between the top ends of the plurality of support rods. The flattening mechanism includes a lifting pressure plate that is slidably provided between the plurality of support rods, and a vertical hydraulic cylinder that is fixedly installed in the top plate and is used to drive the lifting pressure plate to rise and fall.

[0010] As a further optimization of this utility model, a limiting rod is slidably provided at one end of the base plate away from the book pushing mechanism, and the limiting rod is fixedly connected to the top of the inner wall of the machine body.

[0011] As a further optimization of this utility model, a fixed frame is fixedly provided on the outer side of the machine body, and a multi-stage hydraulic cylinder is fixedly installed on the inner side of the fixed frame. The book pushing mechanism includes a connecting plate fixedly provided at one end of the multi-stage hydraulic cylinder, a connecting rod fixedly provided on one side of the connecting plate, and a push plate fixedly provided at one end of the connecting rod for pushing the book core after the top of the machine body is flattened.

[0012] As a further optimization of this utility model, the adjusting plate is fixedly connected to the bottom side of the connecting plate, and the adjusting plate is located between the connecting plate and the push plate.

[0013] As a further optimization of this utility model, a through-hole is provided on one side of the machine body for the adjustment plate to pass through, and a counterweight is fixedly provided on the side of the machine body away from the book pushing mechanism.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The movement of the book pushing mechanism can drive the adjustment plate to move accordingly. Under the guidance of the guide slope, the bottom plate is raised, which drives the roller to move upward. After moving upward, the top of the roller will be exposed from the top of the through hole, raising and supporting the stacked book blocks. When pushing the book later, the rolling of the roller can reduce the friction when the book blocks move, so that the book blocks are not easy to tilt or collapse when pushing the book, and the surface of the bottom layer of book blocks is not easy to wear and crack, which is convenient and practical.

[0016] 2. Through the extension and retraction of the multi-stage hydraulic cylinder, the push plate inside the book pushing mechanism can be moved to facilitate the flattened book core from the top of the machine to other areas for transportation. It can also move the adjustment plate to adjust the height of the rollers. When the adjustment plate moves and disengages from the base plate, the base plate will move down, thereby causing the rollers to move down and retract into the through hole, preventing the top of the rollers from being continuously exposed and hindering the flattening process of the book core. The operation is convenient. Attached Figure Description

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example

[0023] like Figure 1-3 As shown, a book block flattening machine with adjustable function includes a body 1, a flattening mechanism, and a book pushing mechanism. The flattening mechanism is installed on the top of the body 1. Several support rods 11 are fixedly provided at the top edge of the body 1. A top plate 12 is fixedly provided between the top ends of the support rods 11. The flattening mechanism includes a lifting pressure plate 13 slidably disposed between the support rods 11 and a vertical hydraulic cylinder 14 fixedly installed in the top plate 12 for driving the lifting pressure plate 13 to rise and fall. The support rods 11 can connect the top plate 12 and the body 1. The support rods 11 can limit the lifting pressure plate 13. In use, stacked book blocks can be placed in the middle of the top surface of the body 1. After the vertical hydraulic cylinder 14 extends and retracts, it drives the lifting pressure plate 13 to rise and fall. After the lifting pressure plate 13 descends, it can flatten the stacked book blocks on the top of the body 1.

[0024] like Figure 1-3As shown, the top of the machine body 1 has several through holes 2. Each through hole 2 of the machine body 1 is equipped with several rollers 21 for raising the book block to assist in movement when pushing the book. The bottom of the rollers 21 is connected to a base plate 22 inside the machine body 1. The through holes 2 can provide space for the rollers 21 to move up and down. When the rollers 21 are raised, they can raise and support the stacked book blocks on the top. The base plate 22 can support and connect the rollers 21. The outside of the rollers 21 is rotatably connected to a rotating frame, which is fixedly installed on the top of the base plate 22. The rotating frame can connect the rollers 21 and the base plate 22.

[0025] like Figure 1-2 As shown, the book pushing mechanism is installed on one side of the machine body 1 and is used to push the book block after the top of the machine body 1 is flattened. A fixed frame 3 is fixedly installed on the outside of the machine body 1, and a multi-stage hydraulic cylinder 31 is fixedly installed on the inside of the fixed frame 3. The book pushing mechanism includes a connecting plate 32 fixedly installed at one end of the multi-stage hydraulic cylinder 31, a connecting rod 34 fixedly installed on one side of the connecting plate 32, and a push plate 35 fixedly installed at one end of the connecting rod 34 and used to push the book block after the top of the machine body 1 is flattened. The fixed frame 3 can connect the machine body 1 and the multi-stage hydraulic cylinder 31.

[0026] The connecting plate 32 and the connecting rod 34 can connect the multi-stage hydraulic cylinder 31 and the push plate 35. After the multi-stage hydraulic cylinder 31 extends and retracts, it will drive the push plate 35 to move laterally. After moving, the push plate 35 can push the stacked book blocks on the roller 21. A conveyor belt can be set on one side of the machine body 1. The push plate 35 can push the flattened book blocks to the conveyor belt and other areas to facilitate the transportation of the book blocks. The conveyor belt and other conveying equipment are common equipment, and will not be described in detail here.

[0027] like Figure 1-3 As shown, an adjustment mechanism for adjusting the height of the roller 21 is provided on one side of the book pushing mechanism. The adjustment mechanism includes an adjustment plate 33 located on one side of the book pushing mechanism and abutting against the base plate 22. A guide slope is provided between the adjustment plate 33 and the base plate 22 for pressing and raising the base plate 22 by guiding the adjustment plate 33 as it moves into the machine body 1. The adjustment plate 33 is fixedly connected to the bottom side of the connecting plate 32. The adjustment plate 33 is located between the connecting plate 32 and the push plate 35. The connecting plate 32 can connect the adjustment plate 33 and the multi-stage hydraulic cylinder 31, so that when the multi-stage hydraulic cylinder 31 extends or retracts, it will drive the adjustment plate 33 to move laterally.

[0028] When the multi-stage hydraulic cylinder 31 continues to extend, it will push the adjusting plate 33 towards the base plate 22. At this time, under the guidance of the guide slope between the adjusting plate 33 and the base plate 22, the base plate 22 can be lifted vertically, thereby raising the base plate 22 to drive the roller 21 to move upward. After moving upward, the top of the roller 21 will be exposed from the top of the through hole 2 to raise and support the stacked book blocks. When pushing the book later, the rolling of the roller 21 can reduce the friction when the book blocks move, so that the book blocks are not easy to tilt or collapse when pushing the book.

[0029] like Figure 1-3 As shown, a through-hole is provided on one side of the body 1 for the adjustment plate 33 to pass through. A limiting rod 23 is slidably provided on the end of the base plate 22 away from the book pushing mechanism. The limiting rod 23 is fixedly connected to the top of the inner wall of the body 1. The bottom of the adjustment plate 33 is engaged with the bottom of the through-hole of the body 1. The limiting rod 23 consists of a vertical rod passing through the base plate 22 and a limiting block fixed at the bottom of the vertical rod. When the base plate 22 loses the support of the adjustment plate 33 and moves downward, the limiting block of the limiting rod 23 will support the bottom of the base plate 22. The top surface of the limiting block of the limiting rod 23 is higher than the top surface of the adjustment plate 33, so that the bottom surface of the base plate 22 will also be higher than the top surface of the adjustment plate 33 after moving downward. This makes it convenient for the inclined surfaces between the adjustment plate 33 and the base plate 22 to abut against each other and overlap in a certain area when the adjustment plate 33 moves towards the base plate 22, so that the base plate 22 can be lifted up as the adjustment plate 33 continues to move.

[0030] like Figure 1-2 As shown, a counterweight 4 is fixedly provided on the side of the machine body 1 away from the book pushing mechanism. The counterweight 4 can roughly balance the weight on both sides of the machine body 1, so as to prevent the book pushing mechanism side of the machine body 1 from being too heavy and causing the machine body 1 to easily tip over.

[0031] It should be noted that, when using this book block flattening machine with adjustable function, the stacked book blocks are first placed in the middle of the top surface of the machine body 1. After the vertical hydraulic cylinder 14 extends and retracts, it drives the lifting pressure plate 13 to rise and fall. After the lifting pressure plate 13 descends, it can flatten the stacked book blocks on the top of the machine body 1.

[0032] Next, the multi-stage hydraulic cylinder 31 can be controlled to extend continuously, pushing the adjusting plate 33 towards the bottom plate 22. At this time, under the guidance of the guide slope between the adjusting plate 33 and the bottom plate 22, the bottom plate 22 can be vertically lifted, thereby raising the bottom plate 22 to drive the roller 21 to move upward. After moving upward, the top of the roller 21 will be exposed from the top of the through hole 2 to raise and support the stacked book cores. At the same time, after the multi-stage hydraulic cylinder 31 extends, it will use the push plate 35 to push the book cores at the top of the roller 21 to other areas for transportation. When pushing the book, the rolling of the roller 21 can reduce the friction when the book cores move, so that the book cores are not easy to tilt or collapse when pushing the book.

[0033] After the book is pushed, the multi-stage hydraulic cylinder 31 is continuously shortened, which causes the adjusting plate 33 to move in the opposite direction and detach from the base plate 22. At this time, the base plate 22 will move downward under the action of gravity, which will drive the roller 21 to move downward and retract into the through hole 2. This prevents the top of the roller 21 from being continuously exposed and hindering the flattening process of the book core, thereby adjusting the height of the roller 21.

[0034] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
