Description

Technical Field

[0001] This utility model relates to the field of cardboard box production equipment, and in particular to a gluing device for corrugated cardboard box production. Background Technology

[0002] Corrugated cardboard is die-cut, creasing, and stapling or gluing to make corrugated boxes. The gluing process of corrugated boxes is as follows: each end of the cardboard box has a flap. Before gluing, glue needs to be applied to the flap, and then the flap is glued to the other end of the cardboard box. Usually, gluing equipment is used to glue the gluing parts together. As shown in the gluing machine for pressing corrugated boxes disclosed on the China Patent Network (publication announcement number CN220180266U), this type of gluing equipment uses a conveyor belt as the transport carrier to transport the corrugated boxes one by one. When the boxes are transported between the pressing rollers and the conveyor belt, each pressing roller presses the corresponding area, thereby ensuring that the gluing area of ​​the corrugated paper is pressed and improving the yield rate.

[0003] However, the aforementioned disclosed patents and existing corrugated carton gluing equipment in the market still have some shortcomings: the existing method of using conveyor belts to transport and glue corrugated cartons suffers from poor conveying stability, easily leading to skewing during transport, resulting in insufficient conveying and pressing stability and poor gluing and pressing quality. Therefore, those skilled in the art have provided a gluing device for corrugated carton production to solve the problems mentioned in the background art. Utility Model Content

The bottom end of the shaft of each set of the transmission shaft is respectively provided with a bevel gear B that meshes with the bevel gear A.

[0011] As a further technical solution of this utility model: the pusher wheel includes an anti-slip toothed sleeve and a flat pressure shaft ring installed on the upper end of the anti-slip toothed sleeve.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6This utility model provides a technical solution for a gluing device for corrugated cardboard box production: A gluing device for corrugated cardboard box production includes a horizontally opposite base support frame 1 and a conveyor frame 2. Multiple sets of conveyor rollers 3 are arranged and connected to both sides of the support frame 2. Clamping and positioning mechanisms 4 are installed on both sides of the support frame 1. The clamping and positioning mechanisms 4 include two horizontally opposite sets of guide rails 41 and two sets of opposing electric push rods 42 installed between the two sets of guide rails 41 in a forward and reverse alternating manner. Two sets of guide slides 43 are slidably connected to the guide rails 41 along their track direction. The two sets of opposing electric push rods 42 are respectively connected to the two sets of guide slides 43. The guide slide 43 is connected, and two sets of lifting electric push rods 44 of the top support clamping and pushing mechanism 5 are installed at both ends of the guide slide 43. By controlling the extension and braking of the opposing electric push rods 42, the guide slide 43 is pushed to slide along the guide slide rail 41, so that the push wheel 57 in the clamping and pushing mechanism 5 slides horizontally to clamp and limit the corrugated carton on the conveyor roller 3. At the same time, the extension and braking of the lifting electric push rods 44 drives the push wheel 57 in the clamping and pushing mechanism 5 to slide up and down to flat press and limit the corrugated carton on the conveyor roller 3, so that the corrugated carton is kept in a precise flat pushing and conveying state for gluing and pressing.

[0027] Each pair of clamping and positioning mechanisms 4 has two slides equipped with clamping and pushing mechanisms 5 that pass through the conveyor roller 3. The clamping and pushing mechanism 5 includes a brake frame 51, a brake shaft 53 connected to the brake frame 51 in the horizontal direction, and multiple sets of transmission shafts 56 arranged and connected to the brake frame 51 in the vertical direction. A brake motor 52 that drives the brake shaft 53 is installed on one side of the brake frame 51, and multiple sets of bevel gears A54 that are one-to-one with the transmission shafts 56 are arranged and installed on the brake shaft 53 along its shaft direction. Each set of transmission shafts 56 has a bevel gear B55 that meshes with the bevel gear A54 at the bottom of its shaft. By controlling the brake motor 52 to work, the brake shaft 53 is driven to rotate, which in turn drives the bevel gear A54 on its shaft to rotate. The meshing transmission between the bevel gear A54 and the bevel gear B55 drives the transmission shaft 56 to rotate, which pushes the pushing wheel 57 at the top of its shaft to rotate. As a driving source, the corrugated carton on the conveyor roller 3 is driven to be horizontally guided and conveyed for gluing and pressing.

[0028] Each set of drive shafts 56 is directly opposite to two adjacent sets of conveyor rollers 3, and each set of drive shafts 56 has a push wheel 57 installed at the top of its shaft. The push wheel 57 includes an anti-slip toothed sleeve 571 and a flat pressure collar 572 installed on the upper end of the anti-slip toothed sleeve 571. The anti-slip toothed sleeve 571 in the push wheel 57 serves as a clamping drive source to drive the corrugated carton to be pushed flat along the conveyor rollers 3 for feeding. The flat pressure collar 572 is used to flat pressure and limit the corrugated carton, so that the corrugated carton is conveyed in a precise horizontal state for the gluing and pressing process, thereby improving the gluing quality.

[0029] A pressing platform 6, horizontally opposite to the conveyor roller 3, is installed in the middle of the support of the transmission frame 2. Two sets of lifting and positioning mechanisms 8 are installed on both sides of the flat pressing table of the pressing platform 6, and a pressing roller 7 is connected between the two sets of lifting and positioning mechanisms 8. The lifting and positioning mechanism 8 includes a side support frame 81. A lifting slide 82 is slidably connected to the lower end of the support of the side support frame 81, and the lifting slide 82 is bushed with the pressing roller 7. A lifting screw 84 is screwed to the upper end of the support of the side support frame 81. A crank 85 is installed at the top of the lifting screw 84, and a compression frame 83 is connected to the bottom end of the lifting screw 84. The compression frame 83 and the lifting slide 82 are nested together. Next, the compression frame 83 and the lifting slide 82 are connected by a compression spring 86. By turning the knob handle 85, the lifting screw 84 is driven to move up and down. The lifting slide 82 drives the pressure roller 7 to move up and down to maintain a suitable gap with the pressure platform 6. This allows for the roller pressing and gluing of the corrugated carton. Under the elastic bushing of the compression spring 86, the compression frame 83 and the lifting slide 82 maintain an elastic contraction state, so that the pressure roller 7 remains in an elastic rolling state, thus better adapting to the gluing and pressing of corrugated cartons of different thicknesses.

[0030] The working principle of this utility model is as follows: When performing the gluing and pressing work on corrugated cartons, the cartons to be glued are placed flat on the conveyor roller 3. First, the position of the push wheel 57 is pre-adjusted according to the size of the cartons to be glued. Then, during the adjustment process, the opposing electric push rod 42 in the clamping and positioning mechanism 4 is controlled to extend and brake, pushing the guide slide 43 to slide along the guide slide rail 41, so that the push wheels 57 in the two opposing sets of clamping and pushing mechanisms 5 slide horizontally to clamp and limit the corrugated cartons on the conveyor roller 3. At the same time, the extension and braking of the lifting electric push rod 44 is used to drive the push wheels 57 in the clamping and pushing mechanism 5 to slide up and down, so as to flat press and limit the corrugated cartons on the conveyor roller 3, so that the corrugated cartons are kept in a precise flat pushing and conveying state for gluing and pressing work.

[0031] Synchronously, the gap height between the pressure roller 7 and the pressure platform 6 is adjusted according to the thickness of the corrugated carton to maintain a suitable gap with the pressure platform 6, and the corrugated carton is pressed and glued in the form of roller pressing. Then, the crank 85 in the knob lifting and positioning mechanism 8 drives the lifting screw 84 to rise and rotate, and the lifting slide 82 drives the pressure roller 7 to rise and move. Under the elastic bushing of the compression spring 86, the compression frame 83 and the lifting slide 82 maintain an elastic contraction state, so that the pressure roller 7 maintains an elastic rolling state to press and glue the corrugated carton, which is better adapted to the gluing and pressing work of corrugated cartons of different thicknesses.

[0032] Furthermore, by controlling the operation of the brake motor 52 in the clamping and pushing mechanism 5, the brake shaft 53 is driven to rotate. The meshing transmission of bevel gear A54 and bevel gear B55 drives the transmission shaft 56 to rotate, which in turn drives the pushing wheel 57 at the top of the shaft to rotate. As a driving source, the corrugated boxes on the conveying roller 3 are horizontally guided and conveyed, and the corrugated boxes are pushed one by one to the pressure roller 7 and the pressure platform 6 for gluing and pressing. After being pressed, the corrugated boxes are pushed by another set of pushing wheels 57, forming a gluing and pressing operation in an integrated manner of feeding and unloading. The pressing and gluing is flexible and adjustable, and the pressing and gluing quality is more stable.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
