Description

Technical Field

[0001] This utility model relates to the field of packaging box production and processing technology, and in particular to a packaging box gluing module. Background Technology

[0002] In modern packaging production, the forming and sealing of packaging boxes are crucial steps. The quality of the gluing process directly affects the sealing performance, aesthetics, and overall strength of the packaging box. Whether it is for food, pharmaceuticals, electronic products, or daily necessities, the edges or specific parts of the packaging box usually need to be bonded by applying glue. Therefore, the performance and adaptability of the gluing equipment largely determine the efficiency of the production line and the quality of the products.

[0003] Currently, most of the automatic gluing equipment widely used in the market is based on a fixed structure design. The relative position between the gluing head and the flattening component of this type of equipment is usually fixed. In actual production, the materials used to manufacture packaging boxes vary, resulting in significant differences in paper thickness. At the same time, the size and specifications of packaging boxes for different products vary greatly, especially the width. Faced with such diverse needs, traditional fixed gluing modules cannot adapt flexibly, which seriously reduces production flexibility and increases equipment investment and changeover time costs.

[0004] The existing technical solutions have the following drawbacks: when the paper thickness of the packaging box changes, the glue application module with a fixed height is difficult to cope with effectively; for packaging boxes of different widths, the spacing of the positions that need to be glued is also different, and the fixed-spacing dual glue application head mechanism cannot adapt to this change. Utility Model Content

[0005] The purpose of this invention is to provide a packaging box gluing module to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A packaging box adhesive coating module, comprising:

[0008] The support frame has two supports, and the top of the two supports is fixedly installed with the same conveyor belt;

[0009] The lifting mechanism includes two lifting mechanisms, which are symmetrically arranged on the top of the conveyor belt. The two lifting mechanisms are connected to the same connecting component on their adjacent sides, and a pressure roller is rotatably installed at the bottom of the connecting component.

[0010] The assembly includes two glue-applying mechanisms, both of which are slidably mounted on the connecting component.

[0011] By adopting the above technical solution, the lifting mechanism is used to adjust the distance between the connecting component and the top of the conveyor belt, so that the connecting component moves away from or closer to the conveyor belt. This allows the pressure roller to crush packaging boxes of different thicknesses, making the packaging boxes completely flat, which facilitates the gluing mechanism to apply glue to the packaging boxes. This enables the gluing of packaging boxes with different paper thicknesses. The movement of the two gluing mechanisms closer to or further apart adjusts the distance between them, thereby enabling the gluing of packaging boxes with different paper widths. This achieves the goal of flexibly adapting to gluing packaging boxes of different widths and thicknesses.

[0012] In a further embodiment, the lifting mechanism includes a fixed frame, a screw, a movable block, and a handwheel. The fixed frame is fixedly installed on the top of the conveyor belt. The screw is rotatably installed in the fixed frame in a vertical direction. The top of the movable block is provided with a threaded hole that runs through it from top to bottom. The movable block and the screw are threadedly connected. The top end of the screw passes through and extends to the top of the fixed frame. The handwheel is sleeved on the top end of the screw.

[0013] By adopting the above technical solution, the handwheels located on the front and rear sides of the conveyor belt are rotated simultaneously in the same direction, so that the two moving blocks can move up and down synchronously along the screw.

[0014] In a further embodiment, the connecting assembly includes a connecting plate, a first ear plate, a second ear plate, and a round rod. Both sides of the connecting plate are fixedly connected to the movable block. The length of the connecting plate in the left-right direction is greater than the length of the movable block in the left-right direction. The first ear plate and the second ear plate are symmetrically arranged at the bottom of the connecting plate. The top of the connecting plate is provided with a downward receiving groove. The left side of the connecting plate is provided with a rightward limiting groove. The limiting groove and the receiving groove are connected. The round rod is fixedly installed in the receiving groove in the front-back direction. Multiple screw holes are provided at equal intervals on the top right end of the connecting plate.

[0015] By adopting the above technical solution, when the screw rotates within the fixed frame, the moving block can slide up and down within the fixed frame along the direction of the screw without rotating. Thus, when the moving blocks on both sides of the connecting plate move up and down synchronously, the connecting plate can maintain parallel movement in the vertical direction, ensuring the balance of the connecting plate.

[0016] In a further embodiment, the glue application mechanism includes a slider, a slide plate, a glue dispensing head, a U-shaped frame, and a pressure roller. The slider is sleeved on a round rod, and the slider and the round rod are slidably connected. The slide plate is located on the left side of the slider, and the right end of the slide plate passes through a limiting groove and is fixedly connected to the left side of the slider. The glue dispensing head passes through the left end of the slide plate. The U-shaped frame is located at the bottom of the slide plate, and the U-shaped frame includes an open end and a flat end. The flat end of the U-shaped frame is fixedly connected to the slide plate, and the pressure roller is rotatably installed in the open end of the U-shaped frame.

[0017] By adopting the above technical solution, after the glue is discharged from the glue discharge head, the glue pressure roller rolls and applies the glue. The slider can slide in the receiving groove along the length of the round rod, thereby driving the slide plate to slide in the limiting groove, so that the two glue application mechanisms can move away from or towards each other along the round rod.

[0018] In a further embodiment, the top of the slider is higher than the top of the connecting plate, and the top of the slider has mutually opposing horizontal edges extending from the left and right sides. The bottom of the horizontal edges fits into the top of the connecting plate, and the top of the horizontal edge on the right side of the slider is provided with two through holes spaced apart vertically.

[0019] By adopting the above technical solution, two bolts are passed through the through hole from above and then locked into the corresponding screw holes, thereby locking the glue application mechanism in the receiving groove and preventing it from sliding back and forth during the glue application process.

[0020] In a further embodiment, a glue feeding mechanism is also included. Two glue feeding mechanisms are provided, which are respectively located on the front and rear sides of the conveyor belt. Each glue feeding mechanism includes a glue storage pump and a conveying pipe. The glue storage pump is spaced apart on one side of the conveyor belt. One end of the conveying pipe is connected to the outlet of the glue storage pump, and the other end of the conveying pipe is connected to the top of the glue discharge head.

[0021] By adopting the above technical solution, the glue storage pump delivers the glue in the pump into the glue discharge head through the delivery pipeline.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. By setting the length of the connecting plate in the left-right direction to be greater than the length of the moving block in the left-right direction, the connecting plate and the moving block are fixedly connected. When the screw rotates, the moving block is restricted by the connecting plate and will not rotate around the screw, which can achieve the effect of the moving block sliding up and down within the fixed frame without rotating.

[0031] Example 1:

[0032] like Figures 1-4 As shown, a packaging box gluing module includes a support frame 1, a lifting mechanism 3, and a gluing mechanism 6. There are two support frames 1, and the same conveyor belt 2 is fixedly installed on the top of the two support frames 1. The conveyor belt 2 moves from right to left. There are two lifting mechanisms 3, which are symmetrically arranged on the top of the edge of the conveyor belt 2. The two lifting mechanisms 3 are connected to the same connecting component 4 on the side that is close to each other. A pressure roller 5 is rotatably installed at the bottom of the connecting component 4. There are two gluing mechanisms 6, and both gluing mechanisms 6 are slidably installed on the connecting component 4.

[0033] The lifting mechanism 3 includes a fixed frame 31, a screw 32, a movable block 33, and a handwheel 34. The fixed frame 31 is fixedly installed on the top of the side frame of the conveyor belt 2. The screw 32 is rotatably installed in the fixed frame 31 in the vertical direction. The top of the movable block 33 is provided with a threaded hole that runs vertically through it. The movable block 33 and the screw 32 are threadedly connected. The left and right side walls of the movable block 33 are both in contact with the inner wall of the fixed frame 31. The width of the movable block 33 in the front-to-back direction is the same as the width of the fixed frame 31 in the front-to-back direction. The top end of the screw 32 passes through and extends to the top of the fixed frame 31. The handwheel 34 is sleeved on the top end of the screw 32. The connecting assembly 4 includes a connecting plate 41, a first ear plate 42, a second ear plate 43, and a round rod 44. The two sides of the connecting plate 41 are connected to the fixed frame 31. All are fixedly connected to the movable block 33. The length of the connecting plate 41 in the left-right direction is greater than the length of the movable block 33 in the left-right direction. The first ear plate 42 and the second ear plate 43 are symmetrically arranged at the bottom of the connecting plate 41. The top of the connecting plate 41 is provided with a downward receiving groove, and the left side of the connecting plate 41 is provided with a rightward limiting groove. The limiting groove and the receiving groove are connected. The round rod 44 is fixedly installed in the receiving groove in the front-back direction. Multiple screw holes are provided at equal intervals on the top right end of the connecting plate 41. The bottom of the first ear plate 42 and the second ear plate 43 are both higher than the bottom of the pressure roller 5 to prevent the first ear plate and the second ear plate from interfering with the sliding packaging box. The glue application mechanism 6 includes a slider 61, a slide plate 62, a glue dispensing head 63, a U-shaped frame 64 and a pressure roller 5. A rubber roller 65 and a slider 61 are fitted onto a round rod 44, with the slider 61 and the round rod 44 slidably connected. The left side wall, right side wall, and bottom of the slider 61 are all in contact with the inner wall of the receiving groove, which can play a limiting role and facilitate the movement of the slider 61. A sliding plate 62 is located on the left side of the slider 61, and the right end of the sliding plate 62 passes through the limiting groove and is fixedly connected to the left side of the slider 61. The bottom of the sliding plate 62 is in contact with the inner wall of the limiting groove, which can provide a certain support for the sliding plate 62. A glue discharge head 63 is inserted through the left end of the sliding plate 62. The upper and lower ends of the glue discharge head 63 are open, and the glue discharge head 63 is rectangular with a larger top and a smaller bottom, so that the cross-sectional area of ​​the glue gradually decreases during the flow process, which can guide the glue to flow smoothly to the outlet. As a result, a U-shaped frame 64 is set at the bottom of the slide plate 62. The U-shaped frame 64 includes an open end and a flat end. The flat end of the U-shaped frame 64 is fixedly connected to the slide plate 62. The pressure roller 65 is rotatably installed in the open end of the U-shaped frame 64. The bottom of the pressure roller 65 and the pressure roller 5 are coplanar. The length of the pressure roller 65 is greater than the length of the glue discharge head 63 in the front-back direction, so that the pressure roller 65 can better roll the glue discharged from the glue discharge head 63 and ensure the uniformity of glue application. The top of the slider 61 is higher than the top of the connecting plate 41. The top of the slider 61 has mutually opposing horizontal edges on the left and right sides. The bottom of the horizontal edge is attached to the top of the connecting plate 41. Two through holes are provided at intervals on the top of the horizontal edge on the right side of the slider 61.It also includes a glue feeding mechanism 7, of which two are provided, one on the front side and the other on the rear side of the conveyor belt 2. Each glue feeding mechanism 7 includes a glue storage pump 71 and a conveying pipe 72. The glue storage pump 71 is spaced apart on one side of the conveyor belt 2. One end of the conveying pipe 72 is connected to the outlet of the glue storage pump 71, and the other end is connected to the top of the glue discharge head 63. The conveying pipe 72 is detachably connected to both the glue storage pump and the glue discharge head 63, facilitating the replacement with longer or shorter conveying pipes.

[0034] Specific implementation process: First, the thickness of the packaging box is adapted. Two operators simultaneously rotate the handwheels 34 on the lifting mechanisms on both sides of the conveyor belt 2. Since the handwheels 34 are fitted onto the top of the screw 34 and are fixedly connected to the screw 32, the screw 34 will rotate within the fixed frame 31. Consequently, the moving block 33, which is threadedly connected to the screw 34, moves up and down synchronously along the screw 34. The two moving blocks 33 drive the connecting plate 41 to move up and down, thereby adjusting the distance between the connecting plate 41 and the top of the conveyor belt 2 to meet the glue application requirements of packaging boxes of different thicknesses. This allows the pressure roller 5, installed between the first ear plate 42 and the second ear plate 43 at the bottom of the connecting plate 41, to contact the packaging box and crush it, making the packaging box completely flat and creating favorable conditions for subsequent glue application. Next, the glue application width is adjusted. The slider 61 of the glue application mechanism 6 is slidably installed on the round rod 44 in the receiving groove of the connecting plate 41, and can move along the round rod. 44 Slides, pushing slider 61, which in turn drives slide plate 62 to slide within the limiting groove of connecting plate 41. This allows the two gluing mechanisms 6 to move closer or further apart to meet the gluing requirements of packaging boxes of different widths. After determining the position, two bolts are passed through the through holes on the horizontal side of the top of slider 61 and locked in the corresponding screw holes of connecting plate 41 to prevent the gluing mechanism 6 from sliding during the gluing process. Then, the glue feeding mechanism 7 is started. The glue feeding mechanism 7 set on both sides of the conveyor belt 2 starts to work. The glue storage pump 71 continuously feeds glue into the glue discharge head 63 through the conveying pipe 72. After the glue is discharged from the glue discharge head 63, the glue pressing roller 65 under the connecting plate 41 rolls and brushes the glue, so that the glue is evenly attached to the flat surface of the packaging box. Thus, this packaging box gluing module can flexibly adapt to packaging boxes of different widths and thicknesses for efficient gluing, meeting the development trend of small batch, multi-variety, and fast changeover production in modern packaging industry.
