Description

Technical Field

[0001] The present application relates to the technical field of packaging paperboard processing, and in particular to a gluing mechanism for packaging paperboard processing. Background Art

[0002] Packaging cardboard is a paper material used to make various packaging boxes, box packaging, cartons, paper bags and other packaging containers. It is usually made of multiple layers of paper or cardboard materials through bonding or lamination. It has a certain strength and rigidity, can provide protection and support, and protect the internal products from damage.

[0003] Packaging cardboard needs to be glued during the processing. Traditional gluing equipment mostly glues one side of packaging cardboard with fixed thickness. After gluing one side, the packaging cardboard is turned over and glued on the other side. This gluing method is inefficient and easily leads to uneven gluing on both sides or glue deviation, which affects the quality and bonding performance of the packaging cardboard. Utility Model Content

[0004] In view of this, the purpose of the utility model is to solve the shortcomings of the background technology and to propose a gluing mechanism for packaging paperboard processing to solve the problems existing in the prior art.

[0005] To achieve the above purpose, the utility model provides a gluing mechanism for packaging cardboard processing, including a device frame, the inner surface of the device frame is rotatably connected to a first rotating shaft through a transmission mechanism, the outer surface of the first rotating shaft is fixedly sleeved with a first gluing roller, the inner side of the device frame is fixedly connected to a guide bar, the outer surface of the guide bar is slidably connected to a slide through a lifting mechanism, the inner side of the slide is fixedly connected to a second rotating shaft, and the outer surface of the second rotating shaft is rotatably connected to a second gluing roller.

[0006] Preferably, the transmission mechanism includes a main motor fixedly mounted on the device frame, the output end of the main motor is fixedly connected to a driving wheel, and the first gluing roller can be rotated by the transmission mechanism to cooperate with the second gluing roller to transmit the cardboard during the gluing process.

[0007] Preferably, the outer surface of the driving wheel is slidably connected to a conveyor belt, the inner end of the conveyor belt away from the driving wheel is slidably connected to a driven wheel, the axis of the driven wheel is fixedly connected to one end of the first rotating shaft, and the transmission angle between the driving wheel, the conveyor belt and the driven wheel in the transmission mechanism is greater than 120°.

[0008] Preferably, the lifting mechanism comprises an auxiliary motor fixedly mounted on the device frame, the output end of the auxiliary motor is fixedly connected to a driving shaft, and the height of the second glue coating roller can be adjusted by the lifting mechanism.

[0009] Preferably, a side gear is fixedly sleeved on the outer surface of the driving shaft, a screw is rotatably connected to the inner surface of the device frame, and the outer surface of the screw is threadedly sleeved with the inner surface of the slide.

[0010] Preferably, a lower gear is provided at the top of the screw rod, and the outer surface of the lower gear is meshingly connected with the outer surface of the side gear. Two groups of side gears and lower gears are provided, respectively corresponding to the corresponding slides.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The gluing mechanism for processing packaging cardboard can rotate the first gluing roller through a transmission mechanism. Since the packaging cardboard is clamped by two sets of gluing rollers with appropriate force, the first gluing roller will exert force on the second gluing roller through the cardboard during rotation. At this time, the second gluing roller will rotate along the second rotating shaft. The two sets of gluing rollers will simultaneously perform gluing operations on both sides of the packaging cardboard during rotation, thereby reducing the risk of deviation or uneven gluing on one side.

[0013] 2. The gluing mechanism for processing packaging paperboard can adjust the position of the second gluing roller through a lifting mechanism, so that the two sets of gluing rollers can clamp the packaging paperboard with appropriate force, thereby automatically adjusting the position of the gluing roller according to packaging paperboards of different thicknesses, so that the device has strong adaptability and can be suitable for the production of packaging paperboards of various specifications and sizes.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] See also Figure 1-2A gluing mechanism for packaging cardboard processing includes a device frame 1, the inner surface of the device frame 1 is rotatably connected to a first rotating shaft 2 through a transmission mechanism, the outer surface of the first rotating shaft 2 is fixedly sleeved with a first gluing roller 3, the inner side of the device frame 1 is fixedly connected to a guide bar 8, the outer surface of the guide bar 8 is slidably connected to a slide 9 through a lifting mechanism, the inner side of the slide 9 is fixedly connected to a second rotating shaft 10, and the outer surface of the second rotating shaft 10 is rotatably connected to a second gluing roller 11.

[0019] Through the above technical solution, when the device is in use, the height of the second glue coating roller 11 can be adjusted through the lifting mechanism, so that it cooperates with the first glue coating roller 3 to hold the packaging paper box with appropriate force, and finally the first glue coating roller 3 can be driven to rotate under the action of the transmission mechanism, so that when the paperboard is conveyed forward, the two groups of glue coating rollers will simultaneously perform glue coating operations on both sides of the paperboard.

[0020] Specifically, the transmission mechanism includes a main motor 4 fixedly mounted on the device frame 1 , and an output end of the main motor 4 is fixedly connected to a driving wheel 5 .

[0021] Through the above technical solution, the main motor 4 drives the driving wheel 5 to rotate, and the driven wheel 7 rotates through the transmission of the conveyor belt 6.

[0022] Specifically, the outer surface of the driving wheel 5 is slidably connected to the conveyor belt 6, and the inner end of the conveyor belt 6 away from the driving wheel 5 is slidably connected to the driven wheel 7, and the axis of the driven wheel 7 is fixedly connected to one end of the first rotating shaft 2.

[0023] Through the above technical solution, the driven wheel 7 will drive the first rotating shaft 2 to rotate during the self-rotation process, that is, the first glue coating roller 3 will be linked to rotate synchronously.

[0024] Specifically, the lifting mechanism includes an auxiliary motor 12 fixedly mounted on the device frame 1 , and an output end of the auxiliary motor 12 is fixedly connected to a driving shaft 13 .

[0025] Through the above technical solution, when the driving shaft 13 is rotating, the two sets of side gears 14 on the surface thereof will rotate synchronously and drive the corresponding lower gears 16 respectively.

[0026] Specifically, a side gear 14 is fixedly sleeved on the outer surface of the driving shaft 13 , a screw rod 15 is rotatably connected to the inner surface of the device frame 1 , and the outer surface of the screw rod 15 is threadedly sleeved with the inner surface of the slide 9 .

[0027] Through the above technical solution, when the side gear 14 drives the lower gear 16 to rotate, the screw 15 will rotate synchronously with the lower gear 16.

[0028] Specifically, a lower gear 16 is disposed on the top of the screw rod 15 , and an outer surface of the lower gear 16 is meshedly connected with an outer surface of the side gear 14 .

[0029] Through the above technical solution, the gear teeth of the side gear 14 and the lower gear 16 are designed to mesh with each other, so that the two produce meshing action at the contact point. When the side gear 14 rotates, its gear teeth mesh with the gear teeth of the lower gear 16 to form a force transmission mechanism.

[0030] Working principle: When the device is in use, the position of the second glue coating roller 11 is first adjusted according to the thickness of the packaging cardboard to be glued, that is, the auxiliary motor 12 is turned on to drive the drive shaft 13 to rotate. In this process, the two sets of side gears 14 will rotate synchronously with the drive shaft 13, and when the gear teeth of the side gears 14 and the lower gear 16 are in meshing, the pressure angle of the gear teeth determines the lateral force component of the gear. This lateral force component will cause the lower gear 16 to generate a torque, so that it rotates with the side gear 14 while changing the rotation direction, so that the lower gear 16 drives the screw 15 to rotate when rotating. In this process, the slide 9 is limited by the guide bar 8 accordingly, and under the rotation of the screw 15, the slide 9 slides down along the surface of the guide bar 8 until it is adjusted. The first glue coating roller 3 is adjusted to a suitable position from the first glue coating roller 3 so that the packaging cardboard can be smoothly transported during the subsequent gluing process. Finally, the main motor 4 is turned on to drive the driving wheel 5 to rotate. Under the action of the conveyor belt 6, the driven wheel 7 rotates, thereby driving the first glue coating roller 3 to rotate through the first rotating shaft 2. Since the surfaces of the first glue coating roller 3 and the second glue coating roller 11 are coated with a proper amount of glue, and the packaging cardboard is clamped by the two groups of glue coating rollers with a suitable force, the first glue coating roller 3 will apply force to the second glue coating roller 11 through the cardboard during the rotation process. At this time, the second glue coating roller 11 will rotate along the second rotating shaft 10. The two groups of glue coating rollers will simultaneously perform glue coating operations on the two surfaces of the packaging cardboard during the rotation process, and the packaging cardboard can be transported forward.

[0031] In summary, the entire gluing process can be integrated, from adjusting the position of the gluing roller to the gluing operation to the packaging cardboard delivery, all completed in one system. This integrated process can improve production efficiency and reduce production interruptions and errors caused by multiple independent operations.
