Description

Technical Field

[0001] The present invention belongs to the technical field of cover machine design, and particularly relates to a certificate cover machine and a pressure transmission and blanking device thereof. Background Art

[0002] A cover machine generally refers to a cover laminating machine. The cover laminating machine is also called an edge binding machine and a cover machine. It is divided into a manual cover laminating machine, a semi-automatic cover laminating machine, and a full-automatic cover laminating machine. The whole production process includes steps such as cover gluing, positioning, and four-side edge binding. It is applicable to various book covers, book-shaped boxes, file folders, chessboards, desk calendars, and other related products.

[0003] Currently, a Chinese patent with the publication number CN113954548A and the publication date of January 21, 2022, discloses a full-automatic cover machine. The outer shell is placed at the feeding device, coated with glue on the surface of the coating device, and then sent to the cover device. After being corrected by the cardboard suction and fitting device, the cardboard is positioned and fitted with the outer shell. After being edge-bound by the short-side edge binding device, it is conveyed from the previous process through the material transfer driving component to the baffle limiting component. Then, the suction and lifting component rises to adsorb the cardboard at the suction and lifting component. The material transfer opening and closing component moves the two side material transfer devices in opposite directions, thereby expanding the material transfer channel. After the cardboard is separated from the material transfer plate, it is vertically moved down by the suction and lifting component onto the paper feeding component to achieve cardboard material transfer. Then, the cardboard is conveyed by the feeding component and reciprocates in the edge binding channel through the feeding driving component, and the cardboard is intermittently placed at the edge binding component for edge binding, realizing a complete set of coherent actions of continuous material transfer, feeding, edge binding, and blanking, achieving full-automatic integrated processing and production, and improving product efficiency.

[0004] After the cardboard and the outer shell are fitted in the full-automatic cover machine, the edge binding operation and the blanking operation are carried out by using the feeding, edge binding, and blanking device at the tail; however, in the prior art, the tightness of the fit between the blanked cardboard and the outer shell is often insufficient, and it is easy to have the situations of air pockets and flanging, which ultimately is not conducive to improving the product quality. Summary of the Invention

[0005] The purpose of the present invention is to provide a certificate cover machine and a pressure transmission and blanking device thereof, which can compact the blanked cardboard to improve the tightness of the fit between the cardboard and the outer shell.

[0006] The above technical object of the present invention is achieved through the following technical solutions: A pressure transmission and blanking device for a certificate case machine, including a first bracket located at the discharge end of the case machine. A first conveyor belt for the cardboard that has completed the outer shell fitting to fall into is arranged inside the first bracket. A first driving roller is rotatably connected at one end of the first conveyor belt inside the first bracket. A first driven roller is rotatably connected at the other end of the first conveyor belt inside the first bracket. A driving motor with an output shaft connected to the end of the first driving roller is arranged outside the first bracket. A first limiting plate for limiting the cardboard falling on the surface of the first conveyor belt is arranged on the first bracket and above the first conveyor belt. A pressure roller for pressing the cardboard against the first driven roller is arranged above the first driven roller on the upper side of the first bracket. A transmission member is arranged between the pressure roller and the first driven roller.

[0007] By adopting the above technical solutions, when the cardboard that has completed the outer shell fitting is conveyed out from the discharge end of the case machine, the cardboard can fall onto the surface of the first conveyor belt inside the first bracket, and the position of the cardboard on the surface of the first conveyor belt is limited by the first limiting plate. Among them, the driving motor can drive the first conveyor belt to move the cardboard towards the pressure roller side, and at the same time, the transmission member drives the pressure roller to rotate. Then the cardboard can enter between the pressure roller and the first driven roller. At this time, the cardboard can be compacted by the pressure of the pressure roller, and finally it is beneficial to improve the fitting tightness between the cardboard and the outer shell.

[0008] The further setting of the present invention is: Adjusting sleeves are arranged on the upper sides of both ends of the first limiting plate. Adjusting shafts for passing through the adjusting sleeves are fixed on the first bracket. A threaded hole is opened on the upper side of the adjusting sleeve, and a locking threaded shaft with the lower end for abutting against the adjusting shaft is threadedly connected in the threaded hole.

[0009] By adopting the above technical solutions, when the size of the cardboard changes, the adjusting sleeve can be moved along the adjusting shaft by loosening the locking threaded shaft, thereby changing the position of the first limiting plate on the first conveyor belt. Then the locking threaded shaft is tightened so that the lower end of the locking threaded shaft abuts against the adjusting shaft. Finally, the position of the first limiting plate can be adjusted according to the size of the cardboard.

[0010] The further setting of the present invention is: The transmission member includes a first gear arranged at the end of the first driven roller, a transmission shaft arranged at the end of the pressure roller, a connecting shaft rotatably connected on the first bracket and below the first gear, a second gear arranged on the connecting shaft and meshing with the first gear, a first belt pulley arranged on the connecting shaft, a transmission belt sleeved between the first belt pulley and the transmission shaft, a vertical plate arranged on the first bracket and on one side of the transmission shaft, and a long hole opened in the vertical plate for the transmission shaft to pass through.

[0011] By adopting the above technical solution, when the first driving roller rotates, the first driving roller can drive the connecting shaft to rotate through the meshing of the first gear and the second gear, and by sleeving the transmission belt between the first pulley and the transmission shaft, the transmission shaft and the pressure roller can be driven by the transmission belt.

[0012] The further setting of the present invention is that: the transmission member further includes a tensioning cylinder arranged on the side of the first bracket and close to the transmission belt side, and a second pulley rotatably connected to the end of the piston rod of the tensioning cylinder and abutted against the inner side of the transmission belt.

[0013] By adopting the above technical solution, when the cardboard enters the lower side of the pressure roller, the tensioning cylinder is used to drive the second pulley to move so as to tension the transmission belt, thereby increasing the pressure of the pressure roller on the surface of the cardboard, and finally it is further beneficial to improve the fitting tightness between the cardboard and the outer shell.

[0014] The further setting of the present invention is that: it further includes a second bracket arranged at one end of the first bracket and perpendicular to the first bracket, a second transmission belt for the cardboard transmitted from below the pressure roller to fall into is arranged on the second bracket, a second driving roller is rotatably connected at one end of the second transmission belt inside the second bracket, a second driven roller is rotatably connected at the other end of the second transmission belt inside the second bracket, a servo motor with an output shaft connected to the end of the second driving roller is arranged outside the second bracket, and a blowing assembly for blowing and curing the cardboard on the second transmission belt is further arranged on the second bracket.

[0015] By adopting the above technical solution, when the cardboard is transmitted from below the pressure roller, the cardboard can fall onto the second transmission belt inside the second bracket, and the servo motor is used to drive the second transmission belt to transmit, so as to transmit the compacted cardboard out. Among them, by using the blowing assembly on the second bracket, the cardboard transmitted on the second transmission belt can be surface-blown through the blowing assembly, which is beneficial to accelerating the curing of the glue between the cardboard and the outer shell.

[0016] The further setting of the present invention is that: a connecting rod passing over the pressure roller is arranged on the adjusting sleeve close to the pressure roller side, a second limiting rod located above the second transmission belt is arranged at the end of the connecting rod far away from the adjusting sleeve, and the cross section of the second limiting rod is L-shaped and is for the side of the cardboard transmitted from below the pressure roller to abut against.

[0017] By adopting the above technical solution, when the cardboard is transmitted from below the pressure roller, by using the second limiting rod located above the second transmission belt arranged at the end of the connecting rod far away from the adjusting sleeve, and the cross section of the second limiting rod is L-shaped, at this time the second limiting rod can be abutted by the side of the cardboard, which is beneficial to the cardboard being smoothly transmitted from below the pressure roller and falling onto the second transmission belt.

[0018] A further setting of the present invention is that the blowing assembly includes a blowing hood disposed on the side of the second bracket away from the first bracket and opening towards the upper side of the second conveyor belt, an air inlet pipe disposed at the middle position on the side of the blowing hood away from the second bracket, a hot air blower disposed on the side wall of the second bracket, and an air inlet hose with one end connected to the air jet outlet of the hot air blower and the other end connected to the end of the air inlet pipe.

[0019] By adopting the above technical solution, after the hot air blower forms a high-pressure hot air flow, it is supplied to the blowing hood through the air inlet hose. The blowing hood can then jet the hot air flow towards the upper side of the second conveyor belt, and the hot air flow can act on the surface of the cardboard. Since the hot air can accelerate the evaporation of the water in the glue, the glue can be dried and cured faster, and finally the bonding and curing speed between the cardboard and the outer shell can be accelerated.

[0020] A further setting of the present invention is that a first lifting rod is disposed inside the side of the second bracket close to the first bracket, first pushing cylinders are disposed at both ends of the first lifting rod inside the second bracket, a second lifting rod is disposed inside the side of the second bracket away from the first bracket, second pushing cylinders are disposed at both ends of the second lifting rod inside the second bracket, and a mesh baffle is disposed on the side of the second lifting rod away from the second conveyor belt.

[0021] By adopting the above technical solution, when the blowing hood jets the hot air flow towards the upper side of the second conveyor belt, the first pushing cylinder is used to drive the first lifting rod to move upward. At this time, the first lifting rod is located above the second lifting rod, so the cardboard above the second conveyor belt can be tilted upward towards the first lifting rod. At this time, the hot air flow can act on the upper surface of the cardboard; when the first pushing cylinder drives the first lifting rod to move downward and the second pushing cylinder drives the second lifting rod to move upward, at this time the second lifting rod is located above the first lifting rod, so the cardboard above the second conveyor belt can be tilted upward towards the second lifting rod. At this time, the hot air flow can act on the lower surface of the cardboard; by alternately changing the position of the cardboard in this way, it is beneficial for the glue in the cardboard to be fully heated and cured, and further accelerates the bonding and curing speed between the cardboard and the outer shell.

[0022] A further arrangement of the present invention is as follows: The interiors of the first lifting rod and the second lifting rod are both hollow. Nozzles for blowing up the side edges of the cardboard are provided on the upper surfaces of the first lifting rod and the second lifting rod. An air guiding pipe is provided on the lower side of the air jet cover. A bifurcated pipe is provided at the lower end of the air guiding pipe. Branch hoses respectively communicating with the interiors of the first lifting rod and the second lifting rod are provided at both ends of the bifurcated pipe. An air exchange joint in an inverted L shape for communicating the air guiding pipe and the air inlet pipe is provided in the air jet cover. An air guiding hole for docking the air exchange joint is formed on the inner wall of the air jet cover at the position of the air guiding pipe. A push rod that fits on the inner wall of the air jet cover and passes through the air jet cover is provided at the lower end of the air exchange joint. A positioning cylinder is provided at one end of the second bracket away from the second limiting rod. A positioning baffle located above the second conveyor belt is provided at the end of the piston rod of the positioning cylinder. The end of the push rod away from the air exchange joint passes through the air jet cover and is connected to the end of the positioning baffle.

[0023] By adopting the above technical solution, when multiple cardboard sheets are conveyed to one side of the positioning baffle, the multiple cardboard sheets can be butted end to end on the upper surface of the second conveyor belt. At this time, the servo motor is stopped. Then, the positioning cylinder is used to drive the positioning baffle to move backward. The positioning baffle can drive the air exchange joint in the air jet cover to move through the push rod, so that one end of the air exchange joint is docked with the air guiding pipe and the other end is docked with the air inlet pipe. At this time, the hot air flow can enter the air guiding pipe, then enter the interiors of the first lifting rod and the second lifting rod along the branch hoses, and finally the high-pressure air flow can be ejected upward from the nozzles. At this time, the position where each nozzle is located just aligns with the side edge position of the cardboard. Therefore, the air flow ejected upward from the nozzles can drive the side edges of the cardboard to tilt upward. Then, the operator pushes the first cardboard sheet on one side of the positioning baffle toward the side of the cardboard sheet at the back. Multiple cardboard sheets can be quickly stacked together, and there is no need for the operator to stack the cardboard sheets one by one. Finally, it is beneficial for the operator to quickly stack the cardboard sheets.

[0024] The beneficial effects of the present invention are as follows: When the cardboard sheet with the outer shell attached is conveyed out from the discharge end of the leather case machine, the cardboard sheet will first fall onto the surface of the first conveyor belt in the first bracket, and the first limiting plate is used to limit the position of the cardboard sheet on the surface of the first conveyor belt. Among them, the driving motor can drive the first conveyor belt to move the cardboard sheet toward the pressure roller. At the same time, the first driving roller drives the connecting shaft to rotate through the meshing of the first gear and the second gear. The transmission belt is sleeved between the first belt pulley and the transmission shaft. The transmission shaft and the pressure roller can be driven to rotate through the transmission belt. Then, the cardboard sheet can enter between the pressure roller and the first driven roller. At this time, the cardboard sheet can be compacted by the pressure of the pressure roller. Finally, it is beneficial to improve the fitting tightness between the cardboard sheet and the outer shell. After the cardboard is conveyed out from below the pressure roller, the cardboard can fall onto the second conveyor belt within the second support bracket. The servo motor can drive the second conveyor belt to convey, thereby conveying the compacted cardboard out. Among them, after the hot air blower forms high-pressure hot air flow, it is supplied to the air jet cover through the air inlet hose. The air jet cover can jet the hot air flow towards the upper side of the second conveyor belt. The hot air flow can act on the surface of the cardboard. Since the hot air can accelerate the evaporation of the moisture in the glue, the glue can be dried and cured faster, and finally the bonding and curing speed between the cardboard and the outer shell can be accelerated. When the air jet cover jets the hot air flow towards the upper side of the second conveyor belt, the first push cylinder is used to drive the first lifting rod to move upward. At this time, the first lifting rod is located above the second lifting rod. Therefore, the cardboard above the second conveyor belt can tilt upward towards the first lifting rod side. At this time, the hot air flow can act on the upper surface of the cardboard. Then the first push cylinder drives the first lifting rod to move downward, and the second push cylinder drives the second lifting rod to move upward. At this time, the second lifting rod is located above the first lifting rod. Therefore, the cardboard above the second conveyor belt can tilt upward towards the second lifting rod side. At this time, the hot air flow can act on the lower surface of the cardboard. By alternately changing the position of the cardboard in this way, it is beneficial for the glue in the cardboard to be fully heated and cured, and further accelerates the bonding and curing speed between the cardboard and the outer shell. At the same time, when multiple cardboard sheets are conveyed to one side of the positioning baffle, the multiple cardboard sheets can abut against the upper surface of the second conveyor belt end to end. At this time, the servo motor is stopped. Then, the positioning cylinder is used to drive the positioning baffle to move backward. The positioning baffle can drive the air exchange joint in the air jet cover to move through the push rod, so that one end of the air exchange joint is docked with the air guide pipe and the other end is docked with the air inlet pipe. At this time, the hot air flow can enter the air guide pipe, then enter the first lifting rod and the second lifting rod along the branch hose, and finally the high-pressure air flow can be ejected upward from the nozzle. At this time, the position where each nozzle is located just aligns with the side of the cardboard. Therefore, the air flow ejected upward from the nozzle can drive the side of the cardboard to tilt upward. Then the operator pushes the first cardboard on one side of the positioning baffle towards the side of the cardboard at the back, and multiple cardboard sheets can be quickly stacked together, without the operator having to collect the cardboard sheets one by one. Finally, it is beneficial for the operator to quickly collect the cardboard. Description of the Drawings

[0036] Principle: When the cardboard with the outer shell attached is conveyed out from the discharge end of the casing machine, the cardboard first falls onto the surface of the first conveyor belt 11 inside the first bracket 1, and the position of the cardboard on the surface of the first conveyor belt 11 is limited by the first limiting plate 2. The first conveyor belt 11 can be driven by the drive motor 14 to move the cardboard towards the pressure roller 3. At the same time, the first driving roller drives the connecting shaft 43 to rotate through the meshing of the first gear 41 and the second gear 44. By sleeving the transmission belt 46 between the first pulley 45 and the transmission shaft 42, the transmission shaft 42 and the pressure roller 3 can be driven to rotate by the transmission belt 46. Subsequently, the cardboard can enter between the pressure roller 3 and the first driven roller 13. At this time, the cardboard can be compacted by the pressure of the pressure roller 3, which is ultimately beneficial to improving the tightness of the fit between the cardboard and the outer shell. When the cardboard is conveyed out from below the pressure roller 3, the cardboard falls onto the second conveyor belt 51 inside the second bracket 5. The second conveyor belt 51 can be driven by the servo motor 54 to convey the compacted cardboard out. The hot air blower 63 forms a high-pressure hot air flow and supplies it to the air jet cover 61 through the air inlet hose 64. The air jet cover 61 can spray the hot air flow towards the upper side above the second conveyor belt 51, and the hot air flow acts on the surface of the cardboard. Since the hot air can accelerate the evaporation of the moisture in the glue, the glue can be dried and cured faster, and ultimately the bonding and curing speed between the cardboard and the outer shell can be accelerated. When the air jet cover 61 jets hot air towards the upper side of the second conveyor belt 51, the first lifting rod 7 is driven to move upward by the first pushing cylinder 71. At this time, the first lifting rod 7 is located on the upper side of the second lifting rod 8. Therefore, the cardboard above the second conveyor belt 51 can tilt upward towards the first lifting rod 7. At this time, the hot air flow can act on the upper surface of the cardboard. When the first pushing cylinder 71 drives the first lifting rod 7 to move downward and the second pushing cylinder 81 drives the second lifting rod 8 to move upward, the second lifting rod 8 is located on the upper side of the first lifting rod 7. Therefore, the cardboard above the second conveyor belt 51 can tilt upward towards the second lifting rod 8. At this time, the hot air flow can act on the lower surface of the cardboard. By alternately changing the position of the cardboard in this way, it is beneficial for the glue in the cardboard to be fully heated and cured, further accelerating the bonding and curing speed between the cardboard and the outer shell. Meanwhile, when multiple cardboards are transported to one side of the positioning baffle 551, the multiple cardboards can abut against the upper surface of the second conveyor belt 51 end to end. At this time, the servo motor 54 is stopped. Then, the positioning cylinder 55 is used to drive the positioning baffle 551 to move backward. The positioning baffle 551 can drive the ventilation joint 10 in the air jet cover 61 to move through the push rod 101, so that one end of the ventilation joint 10 is docked with the air guide pipe 611 and the other end is docked with the air inlet pipe 62. At this time, the hot air flow can enter the air guide pipe 611, then enter the first lifting rod 7 and the second lifting rod 8 along the branch hose 613, and finally the high-pressure air flow can be ejected upward from the nozzle 9. At this time, the position of each nozzle 9 just aligns with the side of the cardboard. Therefore, the air flow ejected upward from the nozzle 9 can drive the side of the cardboard to tilt upward. Then, the operator takes the first cardboard on one side of the positioning baffle 551 and pushes it towards the side of the cardboard at the back. Multiple cardboards can be quickly stacked together, without the operator having to take and stack the cardboards one by one. Finally, it is beneficial for the operator to quickly stack and store the cardboards. When the operator finishes storing the cardboards, the positioning cylinder 55 drives the positioning baffle 551 to move forward. At this time, the positioning baffle 551 is reset. At the same time, the positioning baffle 551 drives the ventilation joint 10 to move in the reverse direction through the push rod 101, so that the ventilation joint 10 cancels the docking state with the air guide pipe 611 and the air inlet pipe 62. At the same time, the push rod 101 moves to the position of the air guide hole 614, so as to block the position of the air guide hole 614 through the push rod 101. Then, the hot air flow in the air inlet pipe 62 can be ejected from the air jet cover 61 and used again to blow the surface of the cardboard.
