Description

Technical Field

[0001] This invention relates to the field of book block conveying technology, and more particularly to the front-end conveying module of a book block cutting machine. Background Technology

[0002] Before processing, the book cover is a flat surface. It is stacked and transported to the book cover processing station by the conveyor mechanism for shaping. It is then used to cover the book block. The book block is transported one by one by the conveyor mechanism before entering the processing station. Then it is transported to the processing station by the book cover separating mechanism.

[0003] Before processing and cutting, book blocks need to be transported one by one to a designated processing station for cutting in order to be processed into books of the required size. The channel for the book block to move forward in the book block conveying mechanism is usually for one book block to pass through. The book blocks enter the processing station one by one for cutting. When the existing book block conveying mechanism is transporting book blocks, two books are prone to being stacked, which can easily cause jamming and prevent the book blocks from entering the processing station. Summary of the Invention

[0004] The purpose of this invention is to provide a front-end conveying module for a book block cutting machine, addressing the shortcomings of existing technologies.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] The front-end conveying module of the book block cutting machine includes a conveying platform and a book pushing platform connected to the conveying platform, characterized in that:

[0007] The conveying platform includes a conveyor belt and forward conveying side plates arranged on both sides along the forward direction of the conveyor belt. An adjustable-height pressure plate is arranged above the conveyor belt. The book core passes through the bottom of the pressure plate. The position of the pressure plate can be adjusted along the width direction of the conveyor belt.

[0008] The conveying platform is provided with a bottom pressure roller and a top pressure roller at its end. The distance between the bottom pressure roller and the top pressure roller is adjustable. The top pressure roller includes a top feeding roller and a top support seat for mounting the top feeding roller. The top feeding roller is mounted on the top support seat in a longitudinal swing manner. The top support seat is movable in a longitudinal direction and is provided with a buffer assembly for buffering the swing of the top feeding roller.

[0009] The book pushing platform is provided with a book pushing channel for the book to move forward. Along the book pushing channel, there are height limit detection components for detecting the thickness of the book. The height limit detection components include a flip-up height limit plate. The height limit plate is driven by a movable stop plate that stops the book core from entering the book pushing channel. The distance between the height limit plate and the book pushing channel is greater than the thickness of a single book core and less than the thickness of two book cores.

[0010] The beneficial effects of this invention are as follows: When the book block enters the conveying channel, it is pressed and conveyed by the pressure plate and the conveyor belt after passing through the pressure plate, so that the book block will not bounce or shake when it moves forward, and can accurately reach the dropping point at the end of the conveyor belt for precise dropping.

[0011] After the book block is conveyed to the end via the conveyor platform, the top and bottom pressure rollers work together to roll and guide the book block to the next process. It can continue to the next process without pushing the material. When changing different batches or different thicknesses of book blocks, the height of the top pressure roller can be adjusted by moving the top support. When the thickness of the book block in the same batch changes, the top pressure roller can swing longitudinally around the top support to change the distance between it and the bottom pressure roller. Driven by the buffer component, the top pressure roller always maintains rolling contact with the book block, and book blocks of different thicknesses can be rolled forward to the book pushing platform.

[0012] The book blocks advance one by one along the book pushing channel to the next process. When a single book block passes through, it passes under the height limit plate without contacting it. When two or more book blocks overlap, they will contact the height limit plate, causing the plate to flip and trigger an alarm. A stop plate connected to the height limit plate extends, blocking the book blocks from entering the book pushing platform until the staff repairs it. This prevents subsequent books from continuing to pass through and causing jamming, thus reducing the damage rate. Attached Figure Description

[0055] The present invention will now be described in detail with reference to the accompanying drawings.

[0056] like Figure 1-12 As shown, the front-end conveying module of the book block cutting machine includes a conveying platform 1 and a book pushing platform 3 connected to the conveying platform 1.

[0057] The conveying platform 1 includes a conveying channel 10, which includes a conveyor belt 113 and forward conveying side plates 11 arranged on both sides along the forward direction of the conveyor belt 113. An adjustment mechanism 12 is provided between the forward conveying side plates 11 and the forward conveying side plates 11. The adjustment mechanism 12 can adjust the distance between the forward conveying side plates 11 and the forward conveying side plates 11. An adjustable height pressure plate 119 is provided above the conveyor belt 113. The book core passes through the bottom of the pressure plate 119. The pressure plate 119 can be adjusted in position along the width direction of the conveyor belt 113.

[0058] The book block to be transported is placed into the conveyor belt 113. The book block is limited on both sides by the forward conveyor side plates 11 and moves forward. After passing the pressure plate 119, the book block is pressed and transported by the pressure plate 119 and the conveyor belt 113, so that the book block will not bounce or shake when moving forward, and can accurately reach the dropping point at the end of the conveyor belt 113 for precise dropping. In addition, the lateral position and height position of the pressure plate 119 can be adjusted according to the thickness and size of the book block to transport book blocks of various sizes.

[0059] The conveying platform 1 also includes a forward conveying base plate 111 for mounting the conveyor belt 113. Conveying rollers 112 are respectively mounted at both ends of the forward conveying base plate 111. The conveyor belt 113 is fitted onto the forward conveying base plate 111 on which the conveying rollers 112 are mounted. The conveyor belt 113 is mounted with the cooperation of the forward conveying base plate 111 and the conveying rollers 112. Driven by the motor, the conveying rollers 112 are rotated, thereby driving the conveyor belt 113 to move forward, which can convey the book block forward.

[0060] The adjustment mechanism 12 includes an adjustment rod arranged laterally between two forward conveying side plates 11. The adjustment rod is slidably mounted with an adjustment sliding seat connected to the forward conveying side plate 11. Through the cooperation of the adjustment rod and the adjustment sliding seat, the forward conveying side plate 11 is moved to adjust the gap between the two forward conveying side plates 11. This allows for the forward conveying of book blocks of different widths or lengths and limits the position of the book blocks on both sides when they move forward.

[0061] Specifically, the adjusting rods include a first adjusting rod 121 and a second adjusting rod 122 that are parallel to each other. The adjusting sliding seat includes a first adjusting sliding seat 123 that slides with the first adjusting rod 121 and a second adjusting sliding seat 124 that slides with the second adjusting rod 122. The first adjusting sliding seat 123 is connected to one of the forward conveying side plates 11, and the second adjusting sliding seat 124 is connected to the other forward conveying side plate 11. When it is necessary to adjust the distance between the two forward conveying side plates 11, either the first adjusting sliding seat 123 or the second adjusting sliding seat 124 can be moved, or the first adjusting sliding seat 123 and the second adjusting sliding seat 124 can be moved relative to each other simultaneously. The corresponding forward conveying side plate 11 can then move laterally to adjust the distance.

[0062] Preferably, the first adjusting rod 121 and the second adjusting rod 122 are respectively formed with external thread structures 125, and the first adjusting sliding seat 123 and the second adjusting sliding seat 124 are respectively formed with internal thread holes 126 and guide holes 127. When the first adjusting sliding seat 123 or the second adjusting sliding seat 124 is moved, the transmission is achieved through the threaded engagement between the external thread structure 125 and the internal thread hole 126, so that the first adjusting sliding seat 123 or the second adjusting sliding seat 124 can slide accordingly.

[0063] The internal threaded hole 126 of the first adjusting sliding seat 123 is coaxially aligned with the guide hole 127 of the second adjusting sliding seat 124, wherein the guide hole 127 of the first adjusting sliding seat 123 and the internal threaded hole 126 of the second adjusting sliding seat 124 are coaxially aligned; the first adjusting rod 121 passes through the guide hole 127 of the first adjusting sliding seat 123 and the internal threaded hole 126 of the second adjusting sliding seat 124; the second adjusting rod 122 passes through the internal threaded hole 126 of the first adjusting sliding seat 123 and the guide hole 127 of the second adjusting sliding seat 124.

[0064] Correspondingly, the first adjusting rod 121 and the second adjusting rod 122 are rotated. The internal threaded hole 126 of the first adjusting sliding seat 123 is slidably engaged with the external threaded structure 125 of the second adjusting rod 122, and the internal threaded hole 126 of the second adjusting sliding seat 124 is slidably engaged with the external threaded structure 125 of the first adjusting rod 121. The guide hole 127 of the first adjusting sliding seat 123 slides along the second adjusting rod 122, and the guide hole 127 of the second adjusting sliding seat 124 slides along the first adjusting rod 121. The two forward conveying side plates 11 move relative to each other simultaneously, moving away from or closer to each other, thereby adjusting the distance between the two forward conveying side plates 11.

[0065] An adjusting side plate 13 is arranged on the outer side of the forward conveying side plate 11. The first adjusting rod 121 and the second adjusting rod 122 are rotatably installed between the two adjusting side plates 13. The first adjusting rod 121 and the second adjusting rod 122 are each equipped with an adjusting sprocket 131. The adjusting sprocket 131 is connected to the motor drive through a chain, thereby driving the first adjusting rod 121 and the second adjusting rod 122 to rotate, which is used to adjust the distance between the two forward conveying side plates 11.

[0066] Preferably, both the first adjusting sliding seat 123 and the second adjusting sliding seat 124 are equipped with guide seats 132. The guide seats 132 have through holes 134, and a guide rod 133 passes between the two guide seats 132. The two ends of the guide rod 133 are installed on the adjusting side plate 13. When adjusting the spacing of the forward conveying side plate 11, the first adjusting sliding seat 123 and the second adjusting sliding seat 124 slide along the guide rod 133 through the through holes 134, which can improve the sliding stability of the first adjusting sliding seat 123 and the second adjusting sliding seat 124.

[0067] One of the forward conveying side plates 11 is provided with a first mounting rod 114 for mounting a pressure plate 119. When the position of the forward conveying side plate 11 changes, the first mounting rod 114 and the adjusting arm 115 for mounting the pressure plate 119 change their positions accordingly, so that the lateral position of the pressure plate 119 can change.

[0068] The first mounting rod 114 is swayably mounted with an adjusting arm 115. The bottom end of the adjusting arm 115 is rotatably connected to the pressure plate 119. The bottom of the adjusting arm 115 is mounted with a bottom support shaft 116 for rotatably connecting the pressure plate 119. When the height of the pressure plate 119 needs to be adjusted, the adjusting arm 115 is swayed to adjust the height of the pressure plate 119. The height of the pressure plate 119 can be selected according to the thickness of the book block, so as to facilitate the passage of the book block while preventing the book block from bouncing.

[0069] The top of the adjusting arm 115 is provided with a tensioning hole 117 that can be loosely nested in the first mounting rod 114. The tensioning hole 117 is tightened by a screw and a knob. One end of the pressure plate 119 is provided with a guide strip 118 for guiding the book block into the bottom of the pressure plate 119. The guide strip 118 is arranged at an upward angle to form a flared structure, which facilitates the book block to enter the bottom of the pressure plate 119 and passes through easily.

[0070] A roller pressing mechanism 2 is provided at the end of the conveying platform 1. The roller pressing mechanism 2 includes a bottom pressing roller 21 and a top pressing roller 22. The distance between the bottom pressing roller 21 and the top pressing roller 22 is adjustable. The top pressing roller 22 includes a top pressing roller 221 and a top support seat 224 for mounting the top pressing roller 221. The top pressing roller 221 is mounted on the top support seat 224 in a longitudinal swing manner. The top support seat 224 is movable in a longitudinal direction. The top support seat 224 is provided with a buffer assembly 24 for buffering the swing of the top pressing roller 221.

[0071] After the book block is conveyed to the end via the conveyor platform 1, the top pressure roller 22 and the bottom pressure roller 21 cooperate to roll and guide the book block to the next process. It can continue to the next process without pushing the material. When changing different batches or different thicknesses of book blocks, the height of the top pressure roller 221 can be adjusted by moving the top support 224. When the thickness of the book block in the same batch changes, the top pressure roller 221 can swing longitudinally around the top support 224 to change the distance between itself and the bottom pressure roller 21. Driven by the buffer assembly 24, the top pressure roller 221 always maintains rolling cooperation with the book block, and book blocks of different thicknesses can be rolled and advanced to the next process.

[0072] The bottom pressure roller component 21 includes a bottom pressure roller 211 and multiple pressure roller sleeves 212 nested in the bottom pressure roller 211, which can increase the rolling friction of the book block. One end of the top pressure roller 221 is equipped with a friction roller 222 that rolls with the book block. The bottom pressure roller 211 cooperates with the friction roller 222 of the top pressure roller 221 to roll with the top and bottom surfaces of the book block that reach the end of the conveying platform 1, and rolls the book block forward.

[0073] The top pressure roller assembly 22 also includes a lifting drive 23 that drives the top support 224 to move up and down. The lifting drive 23 includes a longitudinally arranged longitudinal guide rod 232 and a longitudinal drive rod 231. The top support 224 is provided with a longitudinal guide hole 233 and a longitudinal drive hole 234 that slide in cooperation with the longitudinal guide rod 232. When the height of the top pressure roller 221 needs to be adjusted, the top support 224 slides longitudinally along the longitudinal drive rod 231 and the longitudinal guide rod 232, so that the height position changes and can be adjusted to facilitate the passage of book blocks of different thicknesses.

[0074] Preferably, the longitudinal drive hole 234 is formed with an external thread structure, and the longitudinal drive hole 234 of the top support 224 is fitted with a longitudinal threaded sleeve 235 that is in transmission engagement with the external thread structure of the longitudinal drive hole 234. When adjusting the height, the top support 224 is threadedly engaged with the rotatable longitudinal drive rod 231 through the longitudinal threaded sleeve 235, and the height of the top support 224 can be adjusted.

[0075] Preferably, the bottom of the longitudinal guide rod 232 is connected to a bottom fixing seat 236, the bottom end of the longitudinal drive rod 231 passes through the bottom fixing seat 236, and a rotatable adjusting drive rod 237 is installed laterally on the bottom fixing seat 236. A first bevel gear 238 is installed on the inner end of the adjusting drive rod 237, and a second bevel gear 239 that meshes with the first bevel gear 238 is installed on the bottom end of the longitudinal drive rod 231. By rotating the adjusting drive rod 237, the first bevel gear 238 of the adjusting drive rod 237 meshes with the second bevel gear 239 at the bottom of the longitudinal drive rod 231, so that the longitudinal drive rod 231 can rotatably engage with the longitudinal threaded sleeve 235 of the top support seat 224 to achieve lifting and lowering adjustment.

[0076] The top pressure roller 221 has a top swing arm 223 nested at one end. The top swing arm 223 is rotatably mounted on the top support 224, so that the top pressure roller 221 can swing up and down around the top support 224, and the friction roller 222 can be finely adjusted to roll with the top surface of the book block.

[0077] The cushioning assembly 24 includes a top fixed seat 241 that is laterally connected to the top support 224. The top fixed seat 241 is equipped with a cushioning cylinder 242 arranged along the forward direction of the book block. The top fixed seat 241 is also equipped with a longitudinally swinging cushioning arm 244. The bottom end of the cushioning arm 244 is rotatably connected to the top swinging arm 223, and the top end of the cushioning arm 244 is rotatably connected to the drive end of the cushioning cylinder 242.

[0078] In its initial state, the buffer cylinder 242 remains in a retracted state, meaning the distance between the top pressure roller 221 and the bottom pressure roller 211 is small. When the book block passes through, the thickness of the book block will push the top pressure roller 221 upward, causing the bottom pressure roller 211 to swing upward. At this time, the buffer cylinder 242 will extend a certain distance under external force, but the buffer cylinder 242 has its own retracting force, allowing the book block to pass through the top pressure roller 221 and the bottom pressure roller 211. The friction roller 222 of the top pressure roller 221 always maintains rolling contact with the top surface of the book block, allowing the book block to be smoothly rolled forward.

[0079] Preferably, the drive end of the buffer cylinder 242 is equipped with a rotatable swing seat 243, which is rotatably connected to the buffer arm 244. The top fixed seat 241 has a longitudinally penetrating movable window 245. The buffer arm 244 is rotatably mounted on the movable window 245. The buffer arm 244 and the top swing arm 223 will generate an arc when swinging. The buffer cylinder 242 is rotatably connected to the buffer arm 244 through the swing seat 243. When the buffer cylinder 242 is buffered and extended, it can cooperate with the buffer arm 244 and the top swing arm 223 to realize the height fine adjustment of the top pressure roller 221. When book blocks of different thicknesses pass through, the roller pressure conveying is maintained.

[0080] Furthermore, the bottom pressure roller 211 is nested with a bottom drive wheel 213, and the top pressure roller 221 is nested with a middle drive wheel 215. The top drive wheel 214 and the middle drive wheel 215 are connected by transmission and rotate synchronously. The friction roller 222 installed on the top pressure roller 221 cooperates with the bottom pressure roller 211 to rotatably press and convey the book core.

[0081] Preferably, a top drive wheel 214 is provided above the top pressure roller 221. A synchronous belt 216 is nested between the top drive wheel 214 and the bottom drive wheel 213. A middle drive wheel 215 abuts against one of the long sides of the synchronous belt 216. The synchronous belt 216 moves to drive the middle drive wheel 215 to rotate. The bottom pressure roller 211 rotates under the transmission connection with the motor. Through the cooperation of the bottom drive wheel 213 and the top drive wheel 214, the synchronous belt 216 moves accordingly. The middle drive wheel 215 installed on the top pressure roller presses against the synchronous belt 216, realizing the transmission connection with the synchronous belt 216. Correspondingly, the rotation of the middle drive wheel 215 drives the top pressure roller to rotate, realizing the synchronous rotation of the bottom pressure roller 211 and the top pressure roller 221.

[0082] The book pushing platform 3 is provided with a book pushing channel 31 for books to move forward. Along the book pushing channel 31, there are height limit detection components 32 for detecting the thickness of books. The height limit detection components 32 include a flip-up height limit plate 322. The height limit plate 322 is connected to a movable stop plate 345 to stop the book core from entering the book pushing channel 31. The distance between the height limit plate 322 and the book pushing channel 31 is greater than the thickness of a single book core and less than the thickness of two book cores.

[0083] Book blocks enter the book pushing channel 31 of the book pushing platform 3 one by one from the conveying channel 10 of the conveying platform 1. The book blocks advance one by one along the book pushing channel 31 to the next process. When a single book block passes through, it will pass under the height limit plate 322 without contacting it. When two or more book blocks pass through overlapping, they will contact the height limit plate 322, which will flip and trigger an alarm. The stop plate 345, which is connected to the height limit plate 322, will extend to block the book blocks from entering the book pushing platform 3 until the staff repairs it. This can prevent subsequent books from continuing to pass through and causing jamming, thus reducing the damage rate.

[0084] The book pushing channel 31 and the conveying channel 10 are perpendicular to each other. After the book block reaches the end of the conveying channel 10, it enters the beginning of the book pushing channel 31. The book pushing channel 31 includes a book pushing conveying base plate 311 and book pushing conveying side plates 312 arranged at intervals along the length direction of the book pushing conveying base plate 311. There are two book pushing conveying side plates 312, and the distance between the two book pushing conveying side plates 312 is adjustable, so that book blocks of different sizes can be pushed forward.

[0085] Preferably, the book conveying base plate 311 is laterally arranged with a lateral adjusting screw 313 for the vertical book conveying side plate 312. The adjusting screw is threadedly connected to one of the book conveying side plates 312. By rotating the lateral adjusting screw 313, the book conveying side plate 312 can be moved, and the distance between it and the other book conveying side plate 312 changes, allowing book blocks of different sizes to advance.

[0086] The height restriction detection component 32 also includes a height restriction pivot 321 for mounting a height restriction plate 322. The height restriction pivot 321 is mounted with a height restriction mounting rod 323. The height restriction plate 322 can move along the length of the height restriction mounting rod 323 to adjust its height. In this embodiment, the height restriction plate 322 can slide with the height restriction mounting rod 323 through a hole, allowing the position of the height restriction plate 322 to change within the height restriction mounting rod 323. When the height restriction mounting rod 323 is arranged longitudinally, the height of the height restriction plate 322 can be adjusted according to different book block thicknesses.

[0087] A sensing module 324 is arranged on the side of the height limiting shaft 321, and a sensing block 325 is installed on the height limiting shaft 321. The sensing block 325 is connected to the sensing module 324 by signal.

[0088] The sensing module 324 and sensing block 325 are existing hardware. After being programmed by software engineers, they form a functional module architecture, and the computer system is controlled by computer program instructions to perform their sensing and control functions. Initially, the sensing block 325 and sensing module 324 are aligned and connected. When the book blocks passing through the book push channel 31 overlap, the book blocks will press against the height limit plate 322, and the height limit shaft 321 will correspondingly rotate and swing. That is, the sensing block 325 installed on the height limit shaft 321 rotates, and a disconnection signal occurs between it and the sensing module 324. The sensing module 324 then sends a signal indicating that it has not received a signal from the sensing block 325, and a corresponding alarm will be issued.

[0089] The forward conveyor side plate is equipped with a telescopic drive component 33 that moves the stop plate 345 in an extended and retractable manner. The telescopic drive component 33 is signal-connected to the sensing module 324. The telescopic drive component 33 and the sensing module 324 are existing hardware. After being programmed by software engineers, a functional module architecture is established, and the computer system is controlled by computer program instructions to complete its sensing and control functions. When the sensing module 324 issues a corresponding alarm, the telescopic drive component 33 operates, causing the stop plate 345 to extend into the conveyor channel 10, stopping the subsequent book blocks and preventing them from entering the book pushing channel 31. After the staff has finished handling the situation, the alarm is deactivated and work can continue.

[0090] Specifically, the telescopic drive component 33 includes a telescopic drive rod 331, with a drive swing arm 332 mounted at the end of the telescopic drive rod 331. The drive swing arm 332 includes an integrally formed drive arm 333 and a driven arm 334 forming an angle. The connection between the drive arm 333 and the driven arm 334 is a swing fulcrum 335. The end of the drive arm 333 is rotatably connected to the end of the telescopic drive rod 331, and the end of the driven arm 334 is drively connected to the stop plate 345. Under the extension and retraction of the telescopic drive rod 331, the drive swing arm 332 can swing to extend the stop plate 345 into the conveying channel 10 to stop the advancing book core. The extension and retraction of the telescopic drive rod 331 is controlled by a signal from the sensing module 324, extending or retracting it.

[0091] Preferably, a horizontally arranged stop support 34 is vertically mounted on the forward conveying side plate. The stop support 34 is equipped with a first rotating shaft 341 and a second rotating shaft 342 connected to the swing fulcrum 335. A guide arm 343 is mounted on the first rotating shaft 341. A stop drive seat 344 is movably connected between the guide arm 343 and the driven arm 334. The stop drive seat 344 is connected to the stop plate 345. The drive swing arm 332 is rotatably mounted on the stop support 34 via the first rotating shaft 341, and the guide arm 343 is rotatably mounted on the stop support 34 via the second rotating shaft 342. When the telescopic drive rod 331 retracts, the drive swing arm 332 swings outward. At this time, under the limitation of the guide arm 343, the stop drive seat 344 swings outward, driving the stop plate 345 to be pulled out from the conveying channel 10, allowing the book block to enter the book pushing channel 31.

[0092] When two or more book blocks overlap, they will contact the height limit plate 322, causing the height limit plate 322 to flip. The height limit shaft 321 will then flip and swing accordingly, causing the sensing block 325 mounted on the height limit shaft 321 to rotate and disconnect from the sensing module 324. The sensing module 324 will then send a signal indicating that it has not received a signal from the sensing block 325, triggering a corresponding alarm. At this time, the telescopic drive rod 331 will extend, driving the swing arm 332 to swing inward. Under the limit of the guide arm 343, the stop drive seat 344 swings inward, causing the stop plate 345 to be inserted laterally into the conveyor channel 10. This stops the book blocks from entering the push-book channel 31. Before entering the push-book channel 31, a single book block will pass through the roller pressing mechanism 2.

[0093] In summary, the present invention possesses the excellent characteristics described above, which enhances its effectiveness in use compared to previous technologies, making it a highly practical product.

[0094] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
