Description

Technical Field

[0001] This utility model relates to the field of glue coating machine technology, and in particular to a glue coating machine for packaging box processing. Background Technology

[0002] During the processing of packaging boxes, it is necessary to firmly connect the various components of the packaging box cardboard together to form a stable three-dimensional structure. It is necessary to apply an appropriate amount of glue to the folded and joined parts of the packaging box cardboard using a glue applicator to achieve a solid bond and ensure that the packaging box can be firmly bonded. In the existing technology, due to the different glue application positions for different styles of packaging box cardboard, positional deviations are prone to occur during the glue application process.

[0003] For example, in the prior art, patent CN221892667U discloses a packaging box processing glue coating machine. In this device, when the packaging box cardboard moves, the outer surface is automatically wiped clean by a cleaning sponge to avoid affecting the adhesion of the glue. When the packaging box cardboard moves forward, it will contact the outer surface of the glue coating roller and drive it to rotate. When the glue coating roller rotates, it will pick up the glue in the glue bucket and automatically apply it to the upper surface of the packaging box cardboard. The operator starts and adjusts the forward and reverse motor to drive the screw to rotate and drive the moving block and glue bucket to move to different positions of different packaging box cardboards, so as to apply glue to different positions of different packaging box cardboards, ensure the accuracy of the glue application position of the packaging box cardboard, ensure the final bonding effect of the packaging box cardboard, and meet different glue application needs. Through the above technical solution, the shortcomings of the prior art are solved.

[0004] However, there is a lateral gap between the drive roller and the coating roller in this device. After the inner side of the packaging cardboard has passed the drive roller, the coating roller is still applying glue to the cardboard. At this time, the cardboard is prone to positional displacement, which affects the coating quality. In addition, the gap between the coating roller and the drive roller and the conveyor belt is fixed, which can only coat packaging cardboard of a single thickness, affecting its practicality. Therefore, a packaging box processing coating machine is designed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a packaging box processing glue coating machine.

[0006] The technical problem to be solved by this utility model is to provide a packaging box gluing machine, which solves the problems in the prior art where the cardboard is prone to positional displacement during the gluing process, affecting the gluing quality and making it impossible to glu packaging box cardboard of different thicknesses.

[0007] This utility model provides a packaging box processing glue coating machine, including a workbench. The upper surface of the workbench is provided with an installation groove, and a belt conveyor is installed in the installation groove. A first bracket is fixedly set in the center of the upper surface of the workbench. A forward and reverse motor is fixedly installed above the outer surface of the first bracket. A lead screw is installed at the output end of the forward and reverse motor. A slider is threaded on the lead screw. A glue coating component is installed on the right side surface of the slider through a lifting component.

[0008] The glue application assembly includes a glue storage cylinder, a mounting plate, a rotating shaft, a glue application roller, and a pressure roller. The mounting plate is fixedly installed on both the inner and outer sides of the bottom surface of the glue storage cylinder. The rotating shaft is rotatably mounted on the two mounting plates via bearings. The glue application roller is fixedly installed in the center of the rotating shaft, and pressure rollers are fixedly installed at both ends of the rotating shaft.

[0009] Preferably, the bottom of the glue storage cylinder is provided with a through groove, and the glue application roller extends into the through groove to block the through groove.

[0010] Preferably, the diameter of the coating roller is the same as the diameter of the pressure roller, and the bottoms of the coating roller and the pressure roller are at the same horizontal height.

[0011] Preferably, the lifting assembly includes an internally threaded sleeve fixedly disposed at the center of the right side surface of the slider, the internally threaded sleeve being internally threadedly connected to an adjusting bolt, and the bottom of the adjusting bolt being rotatably disposed on the upper surface of the glue storage cylinder via a bearing.

[0012] Preferably, the left side surface of the glue storage cylinder is in close contact with the right side surface of the slider.

[0013] Preferably, a second bracket is fixedly installed on the right side of the upper surface of the workbench, a brush is fixedly installed on the inner side of the second bracket, the bottom surface of the brush is attached to the upper surface of the belt conveyor, and a positioning component for positioning the packaging box paper during feeding is fixedly installed on the right side surface of the second bracket.

[0014] Preferably, the positioning assembly includes two bearings fixed at both ends of the right side surface of the second bracket, a second lead screw is rotatably disposed within the two bearings, a wheel is fixedly disposed at the outer end of the second lead screw, a separator ring is fixedly disposed at the center of the second lead screw, and internal threaded rings are threadedly connected to both the inner and outer sides of the second lead screw, and a trapezoidal plate is fixedly disposed on the bottom surface of the internal threaded ring.

[0015] Preferably, the threads on both sides of the separator ring on the second lead screw are in opposite directions.

[0016] Preferably, the bottom surface of the trapezoidal plate is in close contact with the upper surface of the belt conveyor, and the width of the right end of the trapezoidal plate gradually decreases.

[0017] 1. This utility model, by incorporating a gluing roller and a pressure roller, allows for the application of glue to packaging cardboard. The cardboard is placed on the upper right side of a conveyor belt, which then moves it to the left until it is positioned below the pressure roller and gluing roller. The pressure roller holds the cardboard in place, causing the gluing roller to rotate. The gluing roller picks up glue from the glue reservoir and automatically applies it to the surface of the cardboard, achieving the desired gluing effect. Because the pressure roller and gluing roller are aligned, there is no lateral gap, ensuring the pressure roller maintains its position during the gluing process, thus guaranteeing stability and quality.

[0018] 2. This utility model is equipped with a forward and reverse motor, a lead screw, and a slider. The forward and reverse motor drives the lead screw to rotate, and the lead screw drives the slider to move in and out, thereby adjusting the position of the glue coating component. This makes it convenient to apply glue to different positions of the packaging box cardboard and increases its practicality.

[0019] 3. This utility model, by incorporating a lifting component, allows for easy adjustment of the glue-applying device's horizontal height during the glue-applying process on packaging cardboard of varying thicknesses. By rotating the adjusting bolt, the bolt and the internal threaded sleeve move in a threaded motion, causing the glue storage cylinder to rise and fall. This facilitates the application of glue to packaging cardboard of different thicknesses, thus increasing its practicality.

[0020] 4. This utility model, by setting a second support and a brush, allows the packaging cardboard to be cleaned on the upper surface of the packaging cardboard when it is placed on the conveyor belt and moved to the left. This achieves the effect of cleaning dust and impurities on the packaging cardboard, ensuring the cleanliness of the packaging cardboard that needs to be glued, and ensuring the quality of the glue application on the packaging cardboard.

[0021] 5. This utility model, by incorporating a positioning component, allows for precise positioning of the packaging cardboard during the gluing process. The rotating wheel, based on the width of the cardboard, drives the lead screw to rotate, which in turn moves two internal threaded rings and two trapezoidal plates in opposite directions. This ensures that the distance between the left sides of the two trapezoidal plates equals the width of the cardboard, achieving a positioning effect during loading. Furthermore, when gluing the same batch of cardboard, it eliminates the need to adjust the position of the gluing component for each individual cardboard box, increasing work efficiency.

[0029] like Figures 1-4 As shown, an embodiment of this utility model provides a packaging box processing glue coating machine, including a workbench 1. The upper surface of the workbench 1 is provided with an installation groove, and a belt conveyor 2 is installed in the installation groove. A first support 3 is fixedly provided in the center of the upper surface of the workbench 1. A forward and reverse motor 4 is fixedly installed above the outer surface of the first support 3. A lead screw is installed at the output end of the forward and reverse motor 4. A slider 6 is threadedly connected to the lead screw. A glue coating component is installed on the right side surface of the slider 6 through a lifting component.

[0030] The glue application assembly includes a glue storage cylinder 7, a mounting plate 701, a rotating shaft 702, a glue application roller 703, and a pressure roller 704. Mounting plates 701 are fixedly installed on both the inner and outer sides of the bottom surface of the glue storage cylinder 7. A rotating shaft 702 is rotatably mounted on the two mounting plates 701 via bearings. A glue application roller 703 is fixedly installed in the center of the rotating shaft 702, and pressure rollers 704 are fixedly installed at both ends of the rotating shaft 702.

[0031] This invention, by incorporating a gluing roller 703 and a pressure roller 704, allows for the application of glue to packaging cardboard. The cardboard is placed on the right side of the upper surface of a conveyor belt 2, which then moves it to the left until it is positioned below the pressure roller 704 and the gluing roller 703. The pressure roller 704 presses down on the cardboard, causing it to rotate and pick up glue from the glue reservoir. This glue is then automatically applied to the surface of the cardboard, achieving the desired gluing effect. Because the pressure roller 704 and the gluing roller 703 are aligned without any lateral gap, the pressure roller 704 maintains a stable hold on the roller during the gluing process, ensuring consistent gluing quality.

[0032] The system is equipped with a forward and reverse motor 4, a lead screw 1, and a slider 6. The forward and reverse motor 4 drives the lead screw 1 to rotate, and the lead screw 1 drives the slider to move in and out, thereby adjusting the position of the glue coating component. This makes it convenient to apply glue to different positions of the packaging cardboard and increases its practicality.

[0033] In this embodiment, a through groove is provided at the bottom of the glue storage cylinder 7, and the glue coating roller 703 extends into the through groove to block the through groove.

[0034] In this embodiment, the diameter of the coating roller 703 is the same as the diameter of the pressure roller 704, and the bottoms of the coating roller 703 and the pressure roller 704 are at the same horizontal height.

[0035] In this embodiment, the lifting assembly includes an internally threaded sleeve 8 fixedly disposed in the center of the right side surface of the slider 6. An adjusting bolt 801 is internally threadedly connected to the internally threaded sleeve 8. The bottom of the adjusting bolt 801 is rotatably disposed on the upper surface of the glue storage cylinder 7 via a bearing.

[0036] In this embodiment, the left side surface of the glue storage cylinder 7 is in close contact with the right side surface of the slider 6 to ensure the normal lifting and lowering of the glue storage cylinder 7.

[0037] By incorporating a lifting assembly, during the gluing process on packaging cardboard of different thicknesses, rotating the adjusting bolt 801 causes the adjusting bolt 801 to move in a threaded motion with the inner threaded sleeve 8. This lifting and lowering of the adjusting bolt 801 drives the gluing cylinder 7 to move up and down, facilitating the adjustment of the horizontal height of the gluing device. This makes it convenient to apply gluing to packaging cardboard of different thicknesses, increasing its practicality.

[0038] In this embodiment, a second bracket 9 is fixedly installed on the right side of the upper surface of the workbench 1. A brush 901 is fixedly installed on the inner side of the second bracket 9. The bottom surface of the brush 901 is attached to the upper surface of the belt conveyor 2. A positioning component for positioning the packaging box paper during feeding is fixedly installed on the right side surface of the second bracket 9.

[0039] With the second support 9 and brush 901 installed, when the packaging cardboard is placed on the conveyor belt 2 and moves to the left, the brush 901 can clean the upper surface of the packaging cardboard, achieving the effect of cleaning dust and impurities on the packaging cardboard, ensuring the cleanliness of the packaging cardboard that needs to be glued, and ensuring the quality of the glue application on the packaging cardboard.

[0040] In this embodiment, the positioning component includes two bearings 10 fixed at both ends of the right side surface of the second bracket 9. A second lead screw 1001 is rotatably disposed inside the two bearings 10. A rotating wheel 1002 is fixedly disposed at the outer end of the second lead screw 1001. A partition ring 1003 is fixedly disposed in the center of the second lead screw 1001. Both the inner and outer sides of the second lead screw 1001 are threaded with internal threaded rings 1004. A trapezoidal plate 1005 is fixedly disposed on the bottom surface of the internal threaded ring 1004.

[0041] In this embodiment, the thread directions on both sides of the separator ring 1003 on the lead screw 2 1001 are opposite.

[0042] In this embodiment, the bottom surface of the trapezoidal plate 1005 is in close contact with the upper surface of the belt conveyor 2, and the width of the right end of the trapezoidal plate 1005 gradually decreases, so that the packaging box cardboard can be guided between the two trapezoidal plates 1005 during the process of moving to the left.

[0043] This invention, by incorporating a positioning component, allows for the rotation of a rotating wheel 1002 during the gluing process of the packaging cardboard. The rotating wheel 1002 drives a lead screw 1001 to rotate, which in turn moves two internal threaded rings 1004 and two trapezoidal plates 1005 in opposite directions. This ensures that the distance between the left sides of the two trapezoidal plates 1005 equals the width of the packaging cardboard, achieving a positioning effect during loading. Furthermore, during the gluing process of the same batch of packaging cardboard, it eliminates the need to adjust the position of the gluing component for each individual cardboard box, increasing work efficiency.

[0044] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
