Description

Technical Field

[0001] The present application relates to the technical field of book and periodical processing, and in particular to a book and periodical binding device. Background Art

[0002] The processing of books and periodicals generally involves the following steps: plate making, printing, collating, back milling, hot melt adhesive coating, cover gluing, and trimming, ultimately resulting in a finished book with three sides trimmed. The equipment typically used includes plate making machinery, printing presses, perfect binders, and three-sided trimmers.

[0003] A binder is a post-press equipment that binds separated sheets of paper or book pages into thin volumes or books. During the use of the binder, a motor-driven rubber roller is set on the glue pot. Part of the rubber roller is immersed below the liquid level of hot melt glue or other glue. The rotation of the rubber roller can apply glue to the book core, and then stick the pages and the book core together. The glue is continuously consumed with use, and the top of the glue pot is generally set to an open state for the rubber roller to extend out, which will sharply reduce the amount of glue in the glue pot, thereby reducing the amount of glue applied to the book core by the rubber roller, thereby reducing the quality of the books and periodicals after binding. Summary of the Invention

[0004] In order to improve the quality of books and periodicals after binding, the present application provides a book and periodical binding device.

[0005] This application provides a book binding device, which adopts the following technical solutions:

[0006] A book binding device includes a frame, a binding machine body mounted on the frame, a glue pot mounted on the frame and filled with glue, a rubber roller rotatably mounted on the glue pot, and a rotating motor mounted on the glue pot for driving the rubber roller. The glue pot is provided with a maintaining mechanism, and the maintaining mechanism includes:

[0007] A shielding plate is provided on the glue pot and is used to block the glue pot opening and is provided with a clearance hole for the glue roller and glue to pass through;

[0008] A glue filling box is arranged on the glue pot and has a glue filling hole at the bottom that is connected to the glue pot and is filled with glue;

[0009] A push plate is slidably disposed on the inner wall of the glue filling box and is used to push glue into the glue pot and maintain a constant glue liquid level in the glue pot;

[0010] The pushing component is arranged on the glue filling box and drives the pushing plate to move according to the height of the liquid level in the glue pot.

[0011] By adopting the above technical solution, the rotating motor starts to drive the rubber roller to rotate, and the rubber roller applies glue to the book block to achieve gluing, and the shielding plate is used to block the opening of the glue pot, and the rubber roller is immersed in the glue, and the highest point of the rubber roller extends to the outside through the avoidance hole. Therefore, the rubber roller rotates to apply glue to the book block, thereby reducing the probability of glue volatilization and causing the glue level to drop; and after the glue level drops, the pushing component starts to drive the pushing plate to move, and the pushing plate moves to push the glue in the glue filling box to be added to the glue pot through the glue filling hole, so that the glue level in the glue pot is kept constant, thereby reducing the adverse effect of the glue level drop on the glue application, thereby improving the quality of books and periodicals after binding, and the shielding plate also blocks the loss of heat in the glue, reduces energy waste, and achieves energy-saving effects.

[0012] Optionally, the baffle is detachably mounted on the glue pot by screws, and a scraper extending to the side close to the rubber roller is provided on the lower surface of the baffle and on both sides of the avoidance hole. The scraper is used to scrape off excess glue on the rubber roller and flatten the glue on the rubber roller.

[0013] By adopting the above technical solution, the rubber roller rotates, and the scraper is used to scrape off the excess glue on the rubber roller, and also to flatten the glue on the rubber roller, so that the glue distribution on the rubber roller is more even, thereby reducing the probability of glue remaining on the avoidance hole. Moreover, by scraping and flattening the glue, the avoidance hole can be designed to the minimum while meeting the requirements of glue passing through, thereby also reducing the probability of glue volatilization and heat loss through the avoidance hole, further improving the quality of books and periodicals after binding, and also achieving energy saving and environmental protection.

[0014] Optionally, the liquid level in the glue pot is higher than the liquid level in the glue filling box, and the glue filling box is provided with a glue adding mechanism for adding glue into the glue filling box after sealing the glue filling hole, and the pushing component includes:

[0015] A liquid level detector is provided in the glue pot and is used to detect the height of the glue liquid level;

[0016] An electric push rod is provided on the glue filling box and is electrically connected to the liquid level detector and extends to one side of the push plate;

[0017] The top plate is arranged on the piston rod of the electric push rod and is pressed against the push plate and is used to push the push plate to move.

[0018] By adopting the above technical solution, the liquid level detector detects the height of the glue liquid level in the glue pot. When the liquid level is lower than the specified value, the electric push rod starts to drive the top plate to move. The movement of the top plate drives the push plate to move. The movement of the push plate pushes the glue through the glue filling hole into the glue pot, so that the glue liquid level is maintained at a certain level.

[0019] At the same time, when the amount of glue in the glue filling box is too little, the gluing mechanism starts to seal the glue filling hole, and then the electric push rod starts to drive the top plate away from the push plate, and then the gluing mechanism starts to add glue into the glue filling box. As glue is added, the push plate is pushed closer and pressed against the top plate to achieve glue addition. After the addition is completed, the gluing mechanism stops adding glue, and then the gluing mechanism opens the glue filling hole, so that glue can continue to be added to the glue pot, thereby further improving the quality of books and periodicals after binding.

[0020] Optionally, the glue adding mechanism includes:

[0021] A glue adding hose, which is provided on the glue filling box and is used to add glue into the glue filling box and is provided with a glue adding valve;

[0022] A position control component is provided on the glue filling box and controls the glue filling valve to open or close according to the position of the push plate;

[0023] The sealing component is arranged on the glue filling box and is used to control the opening or blocking of the glue filling hole.

[0024] By adopting the above technical solution, when the position control component detects that glue needs to be added to the glue filling box, the closing component starts to seal the glue filling hole, and then the glue filling valve opens, and glue is added to the glue filling box through the glue filling hose. The glue pushes the push plate to move. When the push plate moves and abuts against the top plate, the position control component senses and controls the glue filling hose to close the glue adding, and then the closing component starts to open the glue filling hole so that glue can continue to be added to the glue pot.

[0025] Optionally, the closure assembly includes:

[0026] A closed cylinder is provided on the glue filling box and a piston rod thereof slides along the sliding direction of the push plate and penetrates the push plate;

[0027] A closing plate is provided on the piston rod of the closing cylinder and is used to seal the glue filling hole.

[0028] By adopting the above technical solution, the closing cylinder is started to drive the closing plate to move, and the closing plate blocks or opens the glue filling hole, thereby controlling the opening or blocking of the glue filling hole, and the piston rod of the closing cylinder slides through the push plate, reducing the adverse effects caused by the movement of the push plate.

[0029] Optionally, a support block is provided on the inner wall of the glue pot and below the glue roller, and an arc-shaped storage groove for storing glue is opened on the support block. The storage groove is connected to the glue filling hole, and an insulation component is provided on the storage groove.

[0030] By adopting the above technical solution, the storage groove can meet the needs of adding glue to the glue roller while also reducing the space for storing glue, further reducing the probability of glue in the glue pot escaping through the avoidance hole. At the same time, the insulation component heats and insulates the glue, and reducing the amount of glue in the glue pot also improves the insulation efficiency and energy consumption of the insulation component when insulating the glue, thereby improving the quality of books and periodicals after binding.

[0031] Optionally, the glue roller is provided with a stirring component for stirring the glue in the storage tank, and the glue pot is provided with an arc-shaped rotating groove, and the stirring component includes:

When the moving block is located on one end of the rotating groove, the shifting block rotates to push the moving block to move, and when the moving block moves to the other end of the rotating groove, the shifting block is disengaged from the moving block.

[0035] A return spring is provided on the glue pot and connected to the moving block so that the moving block moves back to its original position after being pushed by the shifting block and presses against the rotating groove for positioning;

[0036] A paddle is provided on the moving block and extends into the storage tank and is used to stir the glue.

[0037] By adopting the above technical solution, the rotation of the rubber roller drives the rotating disk to rotate, the rotation of the rotating disk drives the shifting block to rotate, and after the shifting block contacts the moving block, it pushes the moving block to move on the rotating groove, and then when the moving block moves to the other end of the rotating groove, it disengages from the shifting block, and the moving block moves back under the action of the return spring and presses against the rotating groove for positioning, and the movement of the shifting block drives the shifting piece to move, and the movement of the shifting piece stirs the glue, and at the same time, the rotation of the rotating disk drives the next shifting block to rotate and continue to push the shifting piece to rotate, so as to achieve continuous stirring of the glue, thereby improving the heat preservation effect of the glue and improving the quality of books and periodicals after binding.

[0038] Optionally, the binding machine body includes:

[0039] A plurality of conveying rollers, wherein the plurality of conveying rollers are rotatably arranged on the frame;

[0044] The re-clamping mechanism is arranged on the frame and is used for clamping the joint between the book block and the book pages and can move together with the clamping assembly.

[0045] The book blocks are then moved to the glue rollers for gluing, and the book blocks are moved to the outside of the glue rollers for gluing, and the pages and the book blocks are glued together with glue. The book blocks and the pages are then moved to the fan for cooling. At the same time, the re-clamping mechanism clamps the bonding point between the book blocks and the pages, and the re-clamping mechanism and the clamping assembly drive the book blocks and the pages to move together. When unloading is required, the clamping assembly and the re-clamping mechanism are started and released at the same time, and the book blocks and the pages fall down to realize unloading. Then the clamping assembly continues to move forward, and the re-clamping mechanism moves back to its original position, so as to facilitate the continued clamping of subsequent book blocks and pages, thereby making the bonding point between the book blocks and the pages more firm and improving the quality of the books and periodicals after gluing.

[0050] The clamping plate is arranged on the piston rod of the clamping cylinder and cooperates with the fixing plate to clamp the book block.

[0051] By adopting the above technical solution, the book block is placed between the fixed plate and the clamping plate and rests against the fixed plate for positioning. Then the clamping cylinder is started to drive the clamping plate close to the fixed plate and is used to clamp the book block. When unloading is required, the clamping cylinder is started to drive the clamping plate away from the fixed plate, and the book block falls under the action of gravity to achieve unloading.

Before the clamping plate and the fixed plate clamp the book block, the toggle rod is located outside the follower rod. After the clamping plate and the fixed plate clamp the book block, the toggle rod moves and abuts against the follower rod, thereby driving the sliding seat to move together.

[0056] A double-headed cylinder, wherein the double-headed cylinder is arranged on a sliding seat;

[0057] Two composite clamping plates, which are respectively arranged on the two piston rods of the double-headed cylinder and are used to clamp the book block and the bonding position of the book pages;

[0058] A push-back assembly is provided on the frame and is used for pushing the sliding seat back to its original position.

[0059] When the sliding seat contacts the push-back assembly, the clamping assembly and the re-clamping mechanism stop running, and then the clamping cylinder and the double-headed cylinder are started to release the clamping of the book core and pages, and the book core and pages fall under the action of gravity to achieve unloading.

[0060] When the clamping plate moves away from the fixed plate, the toggle rod moves away from the follower rod, so that the clamping assembly and the re-clamping mechanism move separately, and the clamping assembly continues to move forward. At the same time, the push-back assembly starts to push the sliding seat back to its original position, and then the push-back assembly moves back to its original position, so as to facilitate the continued pushing of the subsequent sliding seats, thereby improving the stability during operation and improving the quality of books and periodicals after binding.

At the same time, the toggle rod 43 extends to the outside of the fixed plate 32, and the rotating motor 13 starts to drive the rubber roller 12 to rotate. After the book block moves, it contacts multiple rubber rollers 12, and glue is applied to the book block. The book block moves to the outside of the rubber roller 12, and then the pages are adhered to the book block. Then the clamping assembly 3 moves to the sliding seat 41, the toggle rod 43 contacts the follower rod 42, and the book block and the pages move between the two composite clamping plates 45. The double-headed cylinder 44 starts to drive the two composite clamping plates 45 to clamp the connection between the book block and the pages, so that the clamping assembly 3 moves and drives the sliding seat 41 to move together. At the same time, the fan 24 cools the glue on the book block and the pages. When the sliding seat 41 abuts against the push-back plate 48, the clamping assembly 3 and the sliding seat 41 stop moving. The clamping cylinder 33 and the double-headed cylinder 44 are started to make the clamping plate 34 move away from the fixed plate 32. At the same time, the two clamping plates 45 move away from each other, so that the book block and the pages fall downward to achieve unloading. The clamping plate 34 drives the toggle rod 43 away from the follower rod 42, so that the clamping assembly 3 is disengaged from the sliding seat 41. Then the push-back cylinder 47 is started to drive the push-back plate 48 and the sliding seat 41 to move back to their original positions. Then the push-back cylinder 47 is started to drive the push-back plate 48 to move back to their original positions, so as to achieve the binding of books and periodicals, thereby improving the quality of the books and periodicals after binding.

[0095] The push plate 53 moves downward to push the glue in the glue filling box 52 to add glue into the storage tank 112. When the sensing block 84 contacts the proximity switch 83 located at the lower position, the closing cylinder 91 is activated to drive the closing plate 92 to move downward to seal the glue filling hole 521. Then the electric push rod 56 is activated to drive the top plate 57 to move upward. Then the control panel controls the glue adding valve 811 to open, and glue is added into the glue filling box 52 through the glue adding hose 81. The glue pushes the push plate 53 to move upward. At the same time, the push plate 53 moves upward to drive the sensing block 84 to move upward. When the push plate 53 moves upward and presses against the push plate 53, the sensing block 84 contacts the proximity switch 83 located at the higher position. The control panel controls the glue adding valve 811 to close and stop glue adding. Then the closing cylinder 91 is activated to drive the closing plate 92 to move upward to open the glue filling hole 521. Then, glue can continue to be added to the storage tank 112, so that the glue liquid level in the storage tank 112 is maintained at a certain height, thereby improving the quality of the books and periodicals after gluing.
