Description

Technical Field

[0001] This utility model relates to the field of packaging box production, specifically a glue-applying device for packaging box production. Background Technology

[0002] Packaging boxes are containers used to hold, protect, and display products. They typically include cardboard boxes, metal boxes, and wooden boxes. During the production of packaging boxes, adhesive is applied to the cardboard, metal plates, and other materials to facilitate the subsequent assembly and use of the packaging boxes. The adhesive firmly bonds the layers of the cardboard (such as the face paper and corrugated core paper) or the joints (such as the joints of a double-slot box) to form a stable structure.

[0003] In existing technologies, during the processing and production of packaging boxes, glue needs to be applied to one side of the packaging box panels. This makes it convenient and simple to assemble multiple panels later, and the assembled packaging box has strong sturdiness. Generally, glue-applying equipment is used to apply glue to the packaging panels by moving a scraper. However, some packaging panels require glue to be applied to both sides. In this case, after applying glue to one side, the panel needs to be flipped. Currently, most cases involve manual or robotic arms to flip the panels. However, manual flipping is not only inefficient but also prone to damaging the panels during the flipping process. While robotic arms can improve flipping efficiency, their maintenance and repair costs are high after long-term use or in case of damage, thus increasing the overall cost of use. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, most cases currently involve manual or robotic arm flipping of the boards. However, manual flipping is not only inefficient but also prone to damaging the boards during the flipping process. While robotic arms can improve flipping efficiency, their maintenance and repair costs are high after long-term use or when they are damaged, thus increasing the overall cost of use. This utility model proposes a glue-applying device for packaging box production.

[0005] The technical solution adopted by the utility model to solve its technical problem is: a glue application device for packaging box production, including a glue application machine body, a bottom block is provided on one side of the glue application machine body, and a flipping mechanism is provided on the top of the bottom block; The flipping mechanism includes a rack, the bottom of which is fixedly connected to the top of a base block. A slider is slidably connected to one side of the base block, and a mounting block is fixedly connected to the top of the slider. A connecting rod is movably connected to the inner cavity of the mounting block. A gear and a placement frame are fixedly connected to both ends of the connecting rod, respectively. The teeth of the gear mesh with the teeth of the rack. A moving component is provided on one side of the base block, and an avoidance component and a limiting component are provided on one side of the gear.

[0006] Preferably, the avoidance component includes a movable block, the surface of which is slidably connected to the inner cavity of the mounting block, the surface of which is disposed on the surface of the gear, a groove is provided on the top of the mounting block, a fixing rod is fixedly connected to one side of the movable block, one end of which is fixedly connected to the top of the movable block, and a first guide plate and a second guide plate are fixedly connected to one side of the bottom block, the first guide plate and the fixing rod being in opposite directions.

[0007] Preferably, the limiting component includes a fixing plate, the bottom of which is fixedly connected to the top of the mounting block, a first sliding rod is slidably connected to the inner cavity of the fixing plate, a wedge block is fixedly connected to one end of the first sliding rod, and a first spring is fixedly connected between one side of the wedge block and one side of the fixing plate.

[0008] Preferably, the moving component includes a servo motor, one side of which is fixedly connected to one side of the base block. The output end of the servo motor passes through the base block and is fixedly connected to a threaded rod. The surface of the threaded rod is threadedly connected to the inner cavity of the slider.

[0009] Preferably, the inner cavity of the placement rack is slidably connected to a second slide rod, the surface of the second slide rod is fixedly connected to a fixing ring plate, a connecting plate is fixedly connected to one side of the placement rack, a second spring is fixedly connected between one side of the fixing ring plate and one side of the connecting plate, the surface of the second slide rod is slidably connected to the inner cavity of the connecting plate, and a pressure plate is fixedly connected to one end of the second slide rod.

[0010] Preferably, a mounting plate is fixedly connected to one side of the glue application machine body, and a heating plate and a fan are fixedly connected to both sides of the mounting plate, respectively.

[0011] Preferably, a reinforcing ring block is fixedly connected to the surface of the connecting rod, and one side of the reinforcing ring block is fixedly connected to one side of the placement frame.

[0012] The advantages of this utility model are: This invention utilizes a servo motor to drive the mounting block and placement frame. After the mounting block moves a certain distance, the placement frame is flipped through the meshing of gears and racks. The contact between the fixed rod and the first guide plate causes the gears to misalign, further enabling the flipping and resetting of the placement frame. This allows for effective flipping of packaging box boards requiring double-sided gluing during adhesive application, improving production and processing efficiency while reducing the cost of flipping boards. It addresses the common problem of manual or robotic arm flipping, which is inefficient and prone to damaging the boards, and while robotic arms offer higher efficiency, their maintenance and repair costs are high after prolonged use or in case of damage, increasing overall operating costs.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail. This application discloses an adhesive application device for packaging box production. (Refer to...) Figure 1 and Figure 5 A glue application device for packaging box production includes a glue application machine body 1, a bottom block 2 is provided on one side of the glue application machine body 1, and a flipping mechanism 3 is provided on the top of the bottom block 2. The flipping mechanism 3 includes a rack 301, the bottom of which is fixedly connected to the top of the base block 2. A slider 304 is slidably connected to one side of the base block 2. A mounting block 306 is fixedly connected to the top of the slider 304. A connecting rod 308 is movably connected to the inner cavity of the mounting block 306. A gear 307 and a placement frame 303 are fixedly connected to both ends of the connecting rod 308, respectively. The teeth of the gear 307 mesh with the teeth of the rack 301. A moving component 305 is provided on one side of the base block 2. An avoidance component 302 and a limiting component 309 are provided on one side of the gear 307.

[0018] The glue application machine body 1 can apply glue to the packaging box material during its operation, thereby achieving the application of glue to the packaging material to facilitate the subsequent assembly of the packaging box. When the glue application machine body 1 is in use, the glue is confined between the scraper and the packaging box. When the scraper or the box moves, the scraper spreads the glue into a uniform thin layer, accurately covering the area that needs to be bonded. The glue application machine body 1 is existing technology in this field, so it will not be described in detail here. The bottom block 2 can connect the rack 301 and the slider 304. The slider 304 can be installed and connected to the connecting rod 308 through the mounting block 306. The connecting rod 308 can connect the placement frame 303 and the gear 307. At the same time, the connecting rod 308 can slide and rotate inside the mounting block 306 through its movable connection with the mounting block 306.

[0019] In addition, the top of the placement rack 303 can be used to place packaging box boards that need to be glued. When the slider 304 moves, it will drive the placement rack 303 and gear 307 to move together through the mounting block 306. The movement of the placement rack 303 can cooperate with the glue application machine body 1 to achieve glue application to the boards. After the glue application is completed, the subsequent movement of the mounting block 306 can generate rotation through the meshing between the gear 307 and the rack 301, thereby using the connecting rod 308 to flip the placement rack 303. At the same time, when the gear 307 meshes with the rack 301, the gear 307 can drive the placement rack 303 to rotate 180 degrees through its own rotation, thereby achieving the smooth flipping of the materials placed on one side of the placement rack 303.

[0020] Reference Figure 5 and Figure 7 The avoidance component 302 includes a movable block 3024, the surface of which is slidably connected to the inner cavity of the mounting block 306. The surface of the movable block 3024 is disposed on the surface of the gear 307. A groove 3025 is formed on the top of the mounting block 306. A fixing rod 3023 is fixedly connected to one side of the movable block 3024, and one end of the fixing rod 3023 is fixedly connected to the top of the movable block 3024. A first guide plate 3021 and a second guide plate 3022 are fixedly connected to one side of the bottom block 2. The first guide plate 3021... The directions of 021 and the fixed rod 3023 are opposite. The bottom block 2 can realize the installation and fixation of the first guide plate 3021 and the second guide plate 3022. At the same time, an arc-shaped groove is opened on one side of the first guide plate 3021 and the second guide plate 3022. The mounting block 306 can connect the moving block 3024. The moving block 3024 can connect the fixed rod 3023. The opening of the sliding groove 3025 allows the fixed rod 3023 to slide smoothly inside the sliding groove 3025.

[0021] Furthermore, the size of the fixed rod 3023 is adapted to the arc-shaped grooves of the first guide plate 3021 and the fixed rod 3023. When the slider 304 moves, driving the gear 307, the placement frame 303, and the connecting rod 308 to move a certain distance, the placement frame 303 can be rotated through the meshing of the gear 307 and the rack 301. Subsequent movement allows the fixed rod 3023 to contact the first guide plate 3021, and pushes the fixed rod 3023 through the arc-shaped groove on one side of the first guide plate 3021, causing it to move. The fixed rod 3023 can then push the gear 307 through its connection with the moving block 3024, thereby... When the mounting block 306 and the placement rack 303 complete their reverse movement, the gear 307 and the rack 301 will no longer be in contact, thus enabling the placement rack 303 to be smoothly reset and preventing it from rotating during the reverse movement. The second guide plate 3022 has a similar function to the first guide plate 3021. After the mounting block 306 moves to a certain distance in the reverse direction, it will contact the fixing rod 3023, causing the fixing rod 3023 and the gear 307 to reset. This allows the gear 307 to re-engage with the rack 301 when it moves closer to the first guide plate 3021, thus causing the placement rack 303 to flip.

[0022] Reference Figure 5 and Figure 7 The limiting component 309 includes a fixing plate 3091. The bottom of the fixing plate 3091 is fixedly connected to the top of the mounting block 306. A first sliding rod 3092 is slidably connected to the inner cavity of the fixing plate 3091. A wedge block 3094 is fixedly connected to one end of the first sliding rod 3092. A first spring 3093 is fixedly connected between one side of the wedge block 3094 and one side of the fixing plate 3091. The mounting block 306 can connect the first sliding rod 3092 and the first spring 3093 through the fixing plate 3091. The first sliding rod 3092 and the first spring 3093 can cooperate with each other to achieve the positioning of the wedge block. The connection of 3094, and the first spring 3093 can apply a pushing force to the wedge block 3094 through its own elasticity, so that the wedge block 3094 can contact the fixing rod 3023. Then, through the pushing force applied by the first spring 3093 to the wedge block 3094, the wedge block 3094 can play a certain limiting role on the fixing rod 3023, so that the fixing rod 3023 can be kept in the corresponding position relatively stably after moving by contacting the first guide plate 3021 or the second guide plate 3022, and is not prone to large displacement during the movement of the mounting block 306.

[0023] Reference Figure 4 and Figure 5The moving component 305 includes a servo motor 3051. One side of the servo motor 3051 is fixedly connected to one side of the base block 2. The output end of the servo motor 3051 passes through the base block 2 and is fixedly connected to a threaded rod 3052. The surface of the threaded rod 3052 is threadedly connected to the inner cavity of the slider 304. The base block 2 can be connected to the threaded rod 3052 through the servo motor 3051. When the servo motor 3051 is operating, it can smoothly drive the threaded rod 3052 to rotate. Then, through the threaded connection between the threaded rod 3052 and the slider 304, it drives the slider 304, the mounting block 306 and the placement frame 303 to move. The movement of the placement frame 303 cooperates with the glue application machine body 1 to achieve glue application on the board.

[0024] Reference Figure 4 and Figure 5 The inner cavity of the placement rack 303 is slidably connected to a second slide rod 9. A fixing ring plate 11 is fixedly connected to the surface of the second slide rod 9. A connecting plate 8 is fixedly connected to one side of the placement rack 303. A second spring 10 is fixedly connected between one side of the fixing ring plate 11 and one side of the connecting plate 8. The surface of the second slide rod 9 is slidably connected to the inner cavity of the connecting plate 8. A pressure plate 12 is fixedly connected to one end of the second slide rod 9. The placement rack 303 can play a certain connecting role for the connecting plate 8 and the second slide rod 9. The fixing ring plate 11 installed on the surface of the second slide rod 9 can cooperate with the connecting plate 8 to realize the installation of the second spring 10. At the same time, the connecting plate 8 can also limit the sliding of the second slide rod 9. The second spring 10 can exert a certain pulling effect on the fixing ring plate 11 and the second slide rod 9 through its own elasticity, so that the second slide rod 9 can clamp and fix the plate placed on one side of the flipping mechanism 3 through the pressure plate 12, so that it can be smoothly glued.

[0025] Reference Figure 3 A mounting plate 5 is fixedly connected to one side of the glue application machine body 1. A heating plate 4 and a fan 6 are fixedly connected to both sides of the mounting plate 5 respectively. The mounting plate 5 can install and connect the heating plate 4 and the fan 6. The heating plate 4 can heat the air around the fan 6. When the fan 6 is in operation, it can blow the surrounding hot air towards the placement rack 303, thereby heating the board placed on one side of the placement rack 303. This makes it less likely that the glue applied to one side of the board will drip in large quantities when it is turned over.

[0026] Reference Figure 1 and Figure 8A reinforcing ring 7 is fixedly connected to the surface of the connecting rod 308. One side of the reinforcing ring 7 is fixedly connected to one side of the placement frame 303. The reinforcing ring 7 can reinforce the installation and connection between the placement frame 303 and the connecting rod 308 through its connection with the placement frame 303 and the connecting rod 308, so that the connecting rod 308 is not easy to shake or tilt when it drives the placement frame 303 to flip.

[0027] Working Principle: When using this device, the operator places the material to be glued onto the top of the placement rack 303. The pressure plate 12 clamps and places the placement rack 303. Then, the operator simultaneously starts the glue application machine body 1 and the servo motor 3051. When the servo motor 3051 is operating, it drives the threaded rod 3052 to rotate. The rotation of the threaded rod 3052 then moves the slider 304, mounting block 306, placement rack 303, and gear 307 together. As the placement rack 303 moves, it moves in conjunction with the glue application machine body 1. The components work together to apply adhesive to one side of the board. After the mounting block 306 moves a certain distance, the gear 307 will contact and mesh with the rack 301. This meshing of gear 307 and rack 301 will cause the connecting rod 308, the placement bracket 303, and the board on one side of the placement bracket 303 to flip. After flipping, the mounting block 306 can continue to move. When the mounting block 306 continues to move a certain distance, the fixing rod 3023 will contact the arc-shaped groove on one side of the first guide plate 3021. Due to the movement of the mounting block 306... The continuous movement causes the fixed rod 3023 to move to one side, pushing the wedge block 3094 during the movement. During this movement, the fixed rod 3023 can also drive the gear 307 to move via the moving block 3024, achieving misalignment between the gear 307 and the rack 301. After the fixed rod 3023 completes its movement, the wedge block 3094 will be reset by the elasticity of the first spring 3093, thus limiting its movement. Then, by reversing the operation of the servo motor 3051, the placement rack 303 can be reset and moved. 03 During the reset movement, it will cooperate with the glue application machine body 1 again to apply glue to the material. After that, the mounting block 306 can continue to reset and move, so that the fixing rod 3023 contacts the second guide plate 3022. The contact between the second guide plate 3022 and the fixing rod 3023 drives the gear 307 to reset, so that the gear 307 can still contact the rack 301 during subsequent movement and drive the placement frame 303 to flip. After that, the glued board only needs to be assembled to complete the processing and production of the packaging box.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
