Description

Technical Field

[0001] This utility model relates to the field of packaging paper products technology, specifically to a packaging paper product printing label pasting device. Background Technology

[0002] Packaging paper products are packaging products made primarily from pulp and paperboard. They need to meet requirements such as being non-toxic, oil-resistant, waterproof, moisture-proof, and airtight. After processing, packaging paper products need to be labeled with labels on their outer surface using a labeling machine.

[0003] Announcement No. CN220363598U discloses a label pasting device for packaging paper products, specifically relating to the field of label pasting technology. It includes a C-shaped plate 1 and a C-shaped plate 2, with a belt connecting them. A C-shaped plate 4 is fixedly mounted on the top of the C-shaped plate 1. A wiping cloth tube, through the elasticity of a spring telescopic rod, can maintain contact with the paper product, facilitating the wiping away of dust from the outer surface of the paper product. The cloth continues to move forward with the belt until it reaches the bottom of the suction pipe, where a vacuum cleaner removes any remaining dust, preventing dust and impurities from causing the label to adhere poorly. The paper product continues to move with the belt until it reaches the bottom of the automatic labeling device, at which point it stops. The automatic labeling device can then immediately apply a label to the paper product. A pressure plate presses down on the labeled paper product, ensuring the label adheres more firmly to its outer surface.

[0004] The aforementioned problems: Most current labeling devices have a significant limitation: after labeling, they cannot flexibly adjust the pressing force according to the size of the product. Typically, the labeling device uses a uniform preset pressing force. For small, thin paper products, excessive pressing force may cause product deformation or even damage. For example, small paper gift boxes are relatively thin and light. If the labeling device presses with the same force as it would on a large, thick cardboard box, the corners of the box are prone to wrinkles or dents, seriously affecting the product's appearance and quality. Therefore, a labeling device for printed paper packaging products is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a label pasting device for printing on packaging paper products, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A label-printing and pasting device for packaging paper products includes a support frame and a conveyor roller. The conveyor roller is rotatably connected inside the support frame, and a conveyor belt is drivenly connected to the outer wall of the conveyor roller. An elastic pressing component for elastically pressing the paper product is provided at the top of the support frame. The elastic pressing component includes a fixing block, the bottom of which is fixedly connected to the top of the support frame. A cylinder is fixedly installed inside the fixing block. A pressing plate is fixedly connected to the telescopic end of the cylinder. A spring is fixedly connected to the bottom of the pressing plate, and an adhesive plate is fixedly connected to the bottom of the spring. An intermittent component for adjusting the speed of the conveyor belt is provided on one side of the support frame.

[0008] The above technical solution involves the coordinated operation of conveyor rollers, conveyor belts, cylinders, extrusion plates, springs, and bonding plates. The elastic pressing component pushes the extrusion plate through the cylinder and connects to the bonding plate using the spring, allowing for elastic pressing of paper products. This adapts to paper products of different thicknesses, ensuring tight and secure label adhesion and improving the quality of the application. The intermittent component adjusts the conveyor belt speed, enabling precise stopping of the paper product during label application, facilitating accurate label application and improving work efficiency.

[0009] A further improvement of the present invention is that the intermittent component includes a fixed frame, one side of which is fixedly connected to the outer wall of the support frame, and a motor is fixedly installed inside the fixed frame.

[0010] By adopting the above technical solution, the fixed frame and the support frame cooperate with each other. The fixed frame provides a stable installation foundation for the motor, ensuring that the motor will not shake or shift during operation. The stable motor installation can ensure its continuous and reliable power output, providing a stable power source for the intermittent components to adjust the conveyor belt gear, and ensuring the normal operation of the device.

[0011] A further improvement of this utility model is that: a limiting frame is fixedly connected to the outer wall of the support frame, and a rotating rod is rotatably connected inside the limiting frame; one side of the rotating rod is fixedly connected to the output end of the motor.

[0012] The above technical solution involves the cooperation of a limit frame, a rotating rod, and a motor. The limit frame limits and supports the rotating rod, enabling it to rotate stably. The motor output is connected to the rotating rod, transmitting its power to the rod and driving it to rotate. This, in turn, drives other components of the intermittent assembly to work, ensuring the accurate and stable operation of the intermittent assembly.

[0013] A further improvement of this utility model is that: a rotating block is fixedly connected to the outer wall of the rotating rod, and there are two sets of rotating blocks. A fixing plate is fixedly connected to the outer wall of the rotating block, and a linkage rod is slidably connected to the inside of the fixing plate and the inside of the rotating block.

[0014] The above technical solution involves the coordinated movement of a rotating block, a fixed plate, and a linkage rod. The rotating block and fixed plate on the rotating rod drive the linkage rod to move. Through the coordination of the linkage rod and the intermittent block, the intermittent movement of the conveyor belt is achieved. The two sets of rotating blocks and fixed plates enhance the stability of the movement and can precisely control the pause and running time of the conveyor belt, making the label pasting more accurate.

[0015] A further improvement of this utility model is that: both the interior of the linkage rod and the interior of the fixing plate are provided with screw holes, and bolts are threaded into the interior of the screw holes, and the interior of the fixing plate and the interior of the linkage rod are detachably connected by bolts.

[0016] By adopting the above technical solution, the screw holes, bolts and linkage rods are designed to cooperate with each other. The screw holes and bolts are designed to facilitate the adjustment of the relative position of the linkage rod and the fixed plate. According to the conveying speed of paper products and the label pasting requirements, the cooperation between the intermittent block and the linkage rod can be flexibly adjusted to achieve precise control of the intermittent movement of the conveyor belt and improve the adaptability and flexibility of the device.

[0017] A further improvement of this utility model is that: an intermittent block is fixedly connected to one side of the conveying roller, and a slot is opened inside the intermittent block; the outer wall of the linkage rod is movably connected to the inside of the slot.

[0018] The above technical solution involves setting up intermittent blocks, empty slots, and the intermittent blocks on one side of the conveyor rollers to cooperate with each other. When the linkage rod moves, it pushes the intermittent blocks to rotate, thereby driving the conveyor rollers to rotate intermittently, thus realizing the intermittent conveying of the conveyor belt. This structural design is simple and reliable, and can accurately control the conveying rhythm of paper products, providing good working conditions for label pasting and improving the accuracy and quality of label pasting.

[0019] Due to the adoption of the above technical solutions, the technological advancements achieved by this utility model compared to the prior art are: it can adapt to paper products of different thicknesses, ensure that the labels are firmly and tightly pasted, improve the pasting quality, and the intermittent component can adjust the conveyor belt speed.

[0020] This utility model provides a label pasting device for packaging paper products. The device uses a cylinder to push an extrusion plate and a spring to connect a bonding plate, which can elastically press the paper products. It can adapt to paper products of different thicknesses, ensuring that the labels are pasted tightly and firmly, thus improving the pasting quality. The intermittent component can adjust the speed of the conveyor belt, allowing the paper products to stop accurately when pasting labels, which facilitates precise label pasting and improves work efficiency.

[0021] This utility model provides a label pasting device for packaging paper products. By setting screw holes, bolts and linkage rods in cooperation, the screw holes and bolts are designed to facilitate the adjustment of the relative position of the linkage rod and the fixed plate. According to the conveying speed of the paper products and the label pasting requirements, the cooperation between the intermittent block and the linkage rod can be flexibly adjusted to achieve precise control of the intermittent movement of the conveyor belt and improve the adaptability and flexibility of the device.

[0028] The present invention will be further described in detail below with reference to embodiments:

[0029] Example 1

[0030] like Figure 1-4As shown, this utility model provides a label pasting device for printing on packaging paper products, including a support frame 1 and a conveyor roller 2. The inside of the support frame 1 and the outer wall of the conveyor roller 2 are rotatably connected. A conveyor belt 3 is drivenly connected to the outer wall of the conveyor roller 2. An elastic pressing component for elastically pressing the paper product is provided on the top of the support frame 1. The elastic pressing component includes a fixing block 4. The bottom of the fixing block 4 is fixedly connected to the top of the support frame 1. A cylinder 5 is fixedly installed inside the fixing block 4. A pressing plate 6 is fixedly connected to the telescopic end of the cylinder 5. A spring 7 is fixedly connected to the bottom of the pressing plate 6. An adhesive plate 8 is fixedly connected to the bottom of the spring 7. An intermittent component for adjusting the gear of the conveyor belt 3 is provided on one side of the support frame 1. The intermittent component includes a fixing frame 9. One side of the fixing frame 9 is fixedly connected to the outer wall of the support frame 1. A motor 10 is fixedly installed inside the fixing frame 9.

[0031] In this embodiment, by setting up the cooperation of conveyor roller 2, conveyor belt 3, cylinder 5, extrusion plate 6, spring 7 and bonding plate 8, the elastic pressing component pushes the extrusion plate 6 through cylinder 5 and connects the bonding plate 8 through spring 7, which can elastically press the paper product, adapt to paper products of different thicknesses, ensure that the label is pasted tightly and firmly, and improve the pasting quality. The intermittent component can adjust the speed of conveyor belt 3, so that the paper product can stop accurately when the label is pasted, which facilitates accurate label pasting and improves work efficiency.

[0032] Example 2

[0033] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a limiting frame 11 is fixedly connected to the outer wall of the support frame 1, a rotating rod 12 is rotatably connected inside the limiting frame 11, one side of the rotating rod 12 is fixedly connected to the output end of the motor 10, a rotating block 13 is fixedly connected to the outer wall of the rotating rod 12, there are two sets of rotating blocks 13, a fixing plate 14 is fixedly connected to the outer wall of the rotating block 13, a linkage rod 15 is slidably connected inside the fixing plate 14 and inside the rotating block 13, screw holes 16 are opened inside the linkage rod 15 and inside the fixing plate 14, bolts 17 are threaded inside the screw holes 16, the inside of the fixing plate 14 and the inside of the linkage rod 15 are detachably connected by bolts 17, an intermittent block 18 is fixedly connected to one side of the conveying roller 2, a slot 19 is opened inside the intermittent block 18, and the outer wall of the linkage rod 15 and the inside of the slot 19 are movably connected.

[0034] In this embodiment, by setting up the mutual cooperation of rotating block 13, fixed plate 14 and linkage rod 15, the rotating block 13 and fixed plate 14 on the rotating rod 12 drive the linkage rod 15 to move. Through the cooperation of linkage rod 15 and intermittent block 18, the intermittent movement of conveyor belt 3 is realized. The two sets of rotating blocks 13 and fixed plates 14 enhance the stability of the movement and can accurately control the pause and running time of conveyor belt 3, making the label pasting more accurate. By setting up the mutual cooperation of screw hole 16, bolt 17 and linkage rod 15, the design of screw hole 16 and bolt 17 facilitates the adjustment of the relative position of linkage rod 15 and fixed plate 14, according to the paper product. The intermittent block 18 and the linkage rod 15 can be flexibly adjusted to meet the conveying speed and label pasting requirements, thereby achieving precise control of the intermittent movement of the conveyor belt 3 and improving the adaptability and flexibility of the device. By setting the intermittent block 18 and the empty trough 19 in cooperation, the intermittent block 18 on one side of the conveyor roller 2 is movably connected to the linkage rod 15. When the linkage rod 15 moves, it pushes the intermittent block 18 to rotate, thereby driving the conveyor roller 2 to rotate intermittently, realizing the intermittent conveying of the conveyor belt 3. This structural design is simple and reliable, and can accurately control the conveying rhythm of paper products, providing good working conditions for label pasting and improving the accuracy and quality of label pasting.

[0035] The working principle of this packaging paper product printing and label pasting device will be explained in detail below.

[0036] like Figure 1-4 As shown, the conveyor roller 2, which is rotatably connected inside the support frame 1, is stationary when the motor 10 is not started. The conveyor belt 3 is wrapped around the outer wall of the conveyor roller 2 and is in a ready-to-run state. The packaging paper products to be labeled are placed on the conveyor belt 3, ready for conveying and labeling operations.

[0037] When the paper product is conveyed to the label pasting position, the cylinder 5 inside the fixing block 4 is activated. The telescopic end of the cylinder 5 pushes the extrusion plate 6 downward, and the spring 7 at the bottom of the extrusion plate 6 is compressed accordingly. The bonding plate 8 connected below the spring 7 contacts the surface of the paper product with appropriate pressure under the action of the spring 7. Since the spring 7 is elastic, it can automatically adjust the pressure of the bonding plate 8 on the paper product according to the thickness of the paper product, so as to achieve elastic pressing on paper products of different thicknesses and ensure that the label can be tightly pasted on the paper product.

[0038] During the label pasting process, in order to ensure that the paper product stays accurately in the pasting position, the intermittent component starts to work, the motor 10 starts, and the output end of the motor 10 drives the rotating rod 12 to rotate within the limit frame 11. The rotating block 13 and the fixed plate 14 fixed on the outer wall of the rotating rod 12 rotate accordingly. The linkage rod 15 slidably connected inside the fixed plate 14 is also driven to move. The two sets of designs of the rotating block 13 and the fixed plate 14 ensure the stability of the movement of the linkage rod 15.

[0039] A slot 19 is provided inside the intermittent block 18 fixed on one side of the conveyor roller 2. The outer wall of the linkage rod 15 is movably connected within the slot 19. When the linkage rod 15 rotates with the rotating block 13 and the fixed plate 14, the linkage rod 15 will push the intermittent block 18 to rotate at a certain angle. The intermittent block 18 drives the conveyor roller 2 to rotate intermittently, thereby enabling the conveyor belt 3 to convey intermittently. When the label is pasted, the conveyor belt 3 stops running, allowing the label to be accurately pasted on the paper product. After pasting is completed, the conveyor belt 3 runs again, transporting the paper product with the pasted label away and transporting the next paper product to be pasted to the pasting position. At the same time, by adjusting the bolt 17 in the screw hole 16, the relative position of the linkage rod 15 and the fixed plate 14 can be changed, thereby adjusting the cooperation between the intermittent block 18 and the linkage rod 15, realizing precise control of the intermittent movement of the conveyor belt 3, and adapting to different label pasting needs.

[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
