Description

Technical Field

[0001] The utility model relates to a gluing device of a perfect binding machine, belonging to the technical field of perfect binding machines. Background Art

[0002] The full name of the perfect binding machine is the wire perfect binding machine. In China, a large number of commonly used books such as textbooks, scientific and technical periodicals, large-scale literary periodicals, novels, etc. are paperback books, and the vast majority of paperback books adopt wire perfect binding. Therefore, the wire perfect binding production line is undoubtedly the most important equipment in bookbinding. With the booming development of post-press processing, it is inevitable for post-press processing to follow the path of digitization, networking, printing integration and on-demand processing. At present, the most important thing is to develop in the direction of post-press diversification, automation, integration of machinery, optoelectronics and intelligence, and linkage. With the change of market demand, the perfect binding process, materials and equipment are constantly innovating, thus promoting profound changes in the appearance of bookbinding.

[0003] Chinese Patent Publication (Publication No.: CN 214027909 U) discloses a gluing device of a perfect binding machine, including a workbench. A glue storage tank is arranged on the upper surface of the workbench. Sliding lead screws are symmetrically arranged on the front and rear sides of the glue storage tank. Clamping mechanisms are arranged on both sliding lead screws; both sides of the top opening of the glue storage tank are provided with chutes, and sliding plates are arranged in both chutes. A driving device is arranged at the bottom of both sliding plates; adopting the above technical solution, the book core is placed downward between the clamping mechanisms, the clamping mechanisms fixedly clamp the book, and slide to directly above the glue storage tank through the sliding lead screws. The clamping mechanisms release the book, and the book core of the book falls into the glue storage tank for gluing. After gluing is completed, the electric telescopic rod is driven, and the book is pushed out of the glue storage tank again through the top plate. After being clamped again by the clamping mechanisms, it slides away from the glue storage tank to complete gluing of the book core. The driving device can drive the sliding plate to close the glue storage tank to realize glue breaking, thus providing a gluing device of a perfect binding machine with high efficiency and safety;

[0004] The above device mainly relies on the extension of two hydraulic cylinders to clamp the book core. However, when the two hydraulic cylinders are not in synchronization, it may cause the book core not to be in the center position of the equipment when clamping the book core, resulting in the deviation of the position of the book core, thus affecting the subsequent normal gluing work of the book core.

[0005] Therefore, a gluing device of a perfect binding machine is proposed. Summary of the Utility Model

[0011] Further preferably, limiting rods are respectively fixedly installed on the front and rear sides of the top of the bottom plate, and the surfaces of the two limiting rods are respectively slidably connected to the inner surfaces of the two first screw blocks.

[0012] Further preferably, moving grooves are respectively opened on the front and rear sides of the top of the bottom plate, and the bottoms of the two moving plates are respectively slidably connected to the inner cavities of the two moving grooves.

[0013] Further preferably, a chute is opened on the top of the mounting rack, and the bottom of the cylinder penetrates through the inner cavity of the chute and extends to the bottom of the mounting rack.

[0014] Further preferably, a slot is formed in the bottom of the glue outlet box, and the glue leveling plate is inserted into the inner cavity of the slot.

[0017] Due to the adoption of the above technical solutions in the embodiments of the present utility model, it has the following advantages:

[0018] 1. By setting the fixing mechanism, through the output of the first servo motor, the bidirectional screw rotates. At this time, the first screw block moves outward and drives the moving plate to move inward. At this time, the connecting rod and the fixing plate move inward synchronously to complete the clamping work of the book core. By fixing the position of the book core, it can effectively avoid the position deviation of the book core when the gluing device contacts the book core, so that the book core moves out of the gluing range of the gluing device, ensuring the stability of the gluing process and facilitating the operation of the operator. By setting the gluing mechanism, through the output of the second servo motor and the mutual cooperation of the synchronous shafts through the transmission belt, the synchronous shaft at the other end can be driven to rotate synchronously. At this time, the synchronous shaft drives the lead screw to rotate, and the screw block drives the slider, the air cylinder, the glue outlet box, the glue discharging nozzle and the glue leveling plate to move. Subsequently, the glue tank transports the glue to the glue outlet box through the corrugated hose, and sprays the glue onto the surface of the book core through the glue discharging nozzle. As the glue leveling plate continues to move, the glue on the surface of the book core is evenly smeared. By automatically gluing the book core, the steps of manual gluing can be reduced, saving a lot of labor costs and facilitating the operation of the operator.

[0019] Second, the utility model limits the movement of the fixed plate by setting a sliding groove, avoiding deviation during the movement of the fixed plate, which may affect the fixing work of the book core. By setting a limiting rod, the movement of the first screw block can be limited, preventing deviation during the movement of the first screw block and thus affecting the limiting work of the book core. By setting a moving groove, the movement of the moving plate can be limited, avoiding a change in direction during the movement of the moving plate, which may affect the stability during the fixing of the book core. By setting a sliding groove, the direction of the movement of the air cylinder can be limited, improving the stability of the glue discharging nozzle and the glue leveling plate during the glue application work on the book core. By setting a slot, it is convenient to disassemble and clean the glue leveling plate, preventing excessive glue adhesion on the surface of the glue leveling plate after the scraping work, which may affect the subsequent normal scraping work. By setting a limiting groove, the movement of the screw block can be limited, avoiding deviation during the movement of the screw block and thus affecting the adjustment work of the positions of the glue leveling plate and the glue discharging nozzle. By setting a support plate, the overall equipment can be stabilized, preventing the equipment from tipping over due to accidental collision, which may affect the glue application work on the book core.

Detailed implementation manners

[0028] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present invention. Therefore, the drawings and the description are considered to be exemplary in nature and not restrictive.

[0029] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0030] Embodiment 1

[0031] As Figures 1-5 shown, the embodiment of the present invention provides a gluing device for a bookbinding machine, including a bottom plate 1. A placing rack 4 is fixedly installed on the top of the bottom plate 1. A mounting rack 5 is fixedly installed on the top of the placing rack 4. A mounting plate 8 is fixedly installed on the top of the mounting rack 5.

[0032] The surface of the bottom plate 1 is provided with a fixing mechanism 2. The fixing mechanism 2 includes a first servo motor 201. The first servo motor 201 is fixedly installed at the bottom of the bottom plate 1. The output end of the first servo motor 201 is fixedly connected with a bidirectional screw 202. Both the upper and lower sides of the surface of the bidirectional screw 202 are threadedly connected with first screw blocks 203. The outer sides of the two first screw blocks 203 are both movably connected with connecting rods 204. The inner sides of the eight connecting rods 204 are all movably connected with mounting blocks 205. The outer sides of the four mounting blocks 205 are all fixedly installed with moving plates 206. The outer sides of the two moving plates 206 are both fixedly installed with connecting rods 207. The inner sides of the two connecting rods 207 are all fixedly installed with fixing plates 208. Sliding grooves 209 are opened on the front and rear sides of the top of the placing rack 4. The bottoms of the two fixing plates 208 are both slidably connected to the inner cavities of the two sliding grooves 209. The front and rear sides of the top of the bottom plate 1 are both fixedly installed with limiting rods 210. The surfaces of the two limiting rods 210 are both slidably connected to the inner surfaces of the two first screw blocks 203. Moving grooves 211 are opened on the front and rear sides of the top of the bottom plate 1. The bottoms of the two moving plates 206 are both slidably connected to the inner cavities of the two moving grooves 211.

[0033] By setting the fixing mechanism 2, through the output of the first servo motor 201, the bidirectional screw 202 rotates. At this time, the first screw blocks 203 move outward and drive the moving plates 206 to move inward. At this time, the connecting rods 207 and the fixing plates 208 move inward synchronously to complete the clamping work of the book core. By fixing the position of the book core, it can effectively avoid the position of the book core shifting when the gluing device contacts the book core, so that the book core moves out of the gluing range of the gluing device, ensuring the stability of the gluing process and facilitating the operation of the operator. By setting the sliding grooves 209, the movement of the fixing plates 208 can be limited to prevent the fixing plates 208 from shifting during movement, thus affecting the fixing work of the book core. By setting the limiting rods 210, the movement of the first screw blocks 203 can be limited to prevent the first screw blocks 203 from shifting during movement, thus affecting the limiting work of the book core. By setting the moving grooves 211, the movement of the moving plates 206 can be limited to prevent the direction of the moving plates 206 from changing during movement, thereby affecting the stability when fixing the book core.

[0034] Embodiment 2

[0035] In one embodiment, a gluing mechanism 3 is provided on the surface of the mounting bracket 5. The gluing mechanism 3 includes a second servo motor 301, which is fixedly installed on the left side of the mounting plate 8. Both the front and rear sides of the top of the mounting bracket 5 are fixedly installed with mounting frames 302. A lead screw 303 is movably connected to the inner side of each of the two mounting frames 302. A nut 304 is threadedly connected to the surface of each of the two lead screws 303. A synchronizing shaft 305 is fixedly installed on the left side of each of the two lead screws 303. A transmission belt 306 is movably connected to the surface of each of the two synchronizing shafts 305. The output end of the second servo motor 301 is fixedly connected to the left side of the transmission belt 306. A slider 307 is fixedly installed inside the two nuts 304. A cylinder 308 is fixedly installed on the top of the slider 307. A glue discharge box 309 is fixedly installed at the bottom of the cylinder 308. A glue discharge nozzle 310 is communicated with the bottom of the glue discharge box 309. A glue leveling plate 311 is arranged on the right side of the bottom of the glue discharge box 309. A glue liquid tank 312 is fixedly installed on the right side of the top of the mounting bracket 5. The output end of the glue liquid tank 312 is communicated with a corrugated hose 313. One end of the corrugated hose 313 away from the glue liquid tank 312 is communicated with the right side of the glue discharge box 309. A chute 315 is formed in the top of the mounting bracket 5. The bottom of the cylinder 308 penetrates through the inner cavity of the chute 315 and extends to the bottom of the mounting bracket 5. A slot 314 is formed in the bottom of the glue discharge box 309. The glue leveling plate 311 is inserted into the inner cavity of the slot 314. A limit groove 316 is formed in the bottom of the inner cavity of each of the two mounting frames 302. The bottom of each of the two nuts 304 is slidably connected to the inner cavity of the two limit grooves 316. Support plates 6 are fixedly installed on the left and right sides of the bottom of the bottom plate 1. Anchor bolts 7 are threadedly connected to the front and rear sides of the surfaces of the two support plates 6.

[0036] By setting up the gluing mechanism 3, through the output of the second servo motor 301, with the mutual cooperation of the synchronous shaft 305 and the transmission belt 306, the synchronous shaft 305 at the other end can be driven to rotate synchronously. At this time, the synchronous shaft 305 drives the lead screw 303 to rotate, and the screw block 304 drives the slider 307, the cylinder 308, the glue outlet box 309, the glue discharging nozzle 310 and the glue leveling plate 311 to move. Subsequently, the glue tank 312 transports the glue to the glue outlet box 309 through the corrugated hose 313, and sprays the glue onto the surface of the book core through the glue discharging nozzle 310. With the continuous movement of the glue leveling plate 311, the glue on the surface of the book core is evenly smeared. By automatically gluing the book core, the steps of manual gluing can be reduced, saving a lot of labor costs and facilitating the operation of the operator. By setting up the chute 315, the direction of movement of the cylinder 308 can be limited, improving the stability of the glue discharging nozzle 310 and the glue leveling plate 311 in gluing the book core. By setting up the slot 314, it is convenient to disassemble and clean the glue leveling plate 311, avoiding excessive glue sticking to the surface of the glue leveling plate 311 after the scraping work, which may affect the subsequent normal scraping work. By setting up the limit groove 316, the movement of the screw block 304 can be limited, preventing the screw block 304 from shifting during movement, which may affect the adjustment of the positions of the glue leveling plate 311 and the glue discharging nozzle 310. By setting up the support plate 6, the overall equipment can be stabilized, avoiding the equipment from tipping over due to accidental collision, which may affect the gluing work of the book core.

[0037] When the utility model is working: First, place the book core inside the fixed plate 208. Subsequently, through the output of the first servo motor 201, the bidirectional screw 202 rotates. At this time, the first screw block 203 moves outward along the surface of the bidirectional screw 202, and the connecting rod 204 flips inward. As the connecting rod 204 flips, the mounting block 205 moves inward synchronously, driving the moving plate 206, the connecting rod 207, and the fixed plate 208 to move inward to complete the fixing work of the book core. Subsequently, through the output of the second servo motor 301, the synchronizing shaft 305 rotates at this time, and through the mutual cooperation of the synchronizing shaft 305 and the transmission belt 306, the synchronizing shaft 305 at the other end rotates synchronously, thereby causing the two lead screws 303 to rotate. At this time, the screw block 304 moves to the left due to the rotation of the lead screw 303. As the screw block 304 moves, the slider 307 drives the cylinder 308, the glue outlet box 309, the glue discharging nozzle 310, and the glue leveling plate 311 to move to the left synchronously. Then, the glue in the glue tank 312 is conveyed into the inner cavity of the glue outlet box 309 through the corrugated hose 313. Through the extension of the cylinder 308, the glue outlet box 309, the glue discharging nozzle 310, and the glue leveling plate 311 move downward synchronously. At the same time, since the glue outlet box 309 is in a moving state, the glue discharging nozzle 310 passes over the surface of the book core and sprays glue on its top. Subsequently, the glue outlet box 309 continues to move to the left, and the glue leveling plate 311 evenly scrapes the glue on the surface of the book core, so that the glue is evenly on the surface of the book core, thus completing the gluing work of the book core.

[0038] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
