Description

Technical Field

[0001] The utility model relates to the technical field of box gluing machines, in particular to a box gluing machine which can adjust the moving speed of paperboards. Background Art

[0002] The box gluing machine is a machine used to gluing cardboard during the process of processing cardboard into paper boxes. Traditional gluing machines are limited by cost and other reasons. Some machines do not have a speed regulation structure. Therefore, the feeding and moving speed of the cardboard is fixed and cannot be adjusted according to the actual working conditions. When the machine is gluing the cardboard, the glue is difficult to be evenly distributed on the surface of the cardboard due to the cardboard moving speed being too fast. There is no glue in some areas, and the cardboard cannot be bonded together, which reduces the quality of the carton. If the cardboard is moved too slowly, it will cause too much glue to be applied, resulting in an uneven surface of the carton after the glue dries, reducing the aesthetics of the carton surface. Moreover, the cardboard is easily damaged after the glue soaks the cardboard, and the drying time is also long, which also reduces the production efficiency of the carton.

[0012] In summary, the beneficial effects of the present invention are:

[0013] 1. The utility model adopts a structural design that can adjust the moving speed of the cardboard, so that the moving speed of the cardboard and the discharging speed can be switched between fast and slow. In this way, cardboards of different thicknesses can be moved at the speed set by the user during transfer, ensuring the uniformity of glue distribution when gluing the cardboard, avoiding the problem of cardboards not being bonded together due to uneven glue distribution during carton forming, improving the processing quality of the carton, and providing convenience for users' work.

[0014] 2. The utility model provides a limit slider and a limit slide groove. When the adjusting frame moves and adjusts, the limit slider will also move with the adjusting frame.

As the distance between the pressure roller and the cardboard decreases, the friction between the pressure roller and the cardboard will also increase, and it will be greater than the friction between the two conveyor belts and the cardboard. The pressure roller also rotates, so the cardboard can be pushed out quickly. At this time, the movement speed of the cardboard is fast. On the contrary, if the distance between the pressure roller and the cardboard becomes larger, the friction will be weakened. At this time, the friction is less than that of the two conveyor belts. Therefore, the cardboard can only be sent out at the speed of the two conveyor belts. This provides users with more and more flexible choices for work and provides convenience for users.

As the adjusting frame moves, the positioning pin will first move out of the corresponding positioning hole, compressing the spring at the same time, and then move to the next positioning hole during the movement, and be inserted into the current positioning hole under the push of the spring, and then move out of the current positioning hole and be inserted into the next positioning hole again until the adjusting frame stops moving after adjustment. At this time, under the push of the spring, the positioning pin will be inserted into the positioning hole at the current position, thereby realizing the positioning of the adjusting frame and the working position of the pressure roller, providing convenience for the user's work.

[0017] 5. The utility model sets the conveying roller 1, conveying roller 2 and conveying roller 3. When the machine is working, the conveying roller 1, conveying roller 2 and conveying roller 3 will rotate at the same time and in the same direction. In this way, in cooperation with the conveyor belt 1 and the conveyor belt 2, the cardboard can be conveyed, which provides convenience for the user's work.

[0018] 6. The utility model is provided with a fixing frame, a mounting frame and a flattening wheel. The mounting frame and the flattening wheel are used to press down the cardboard. When the cardboard moves, the mounting frame can prevent the cardboard from deflecting and the edge from warping, and the flattening wheel can reduce the friction between the mounting frame and the cardboard, thereby ensuring smooth movement of the cardboard and providing convenience for the user's work.

DETAILED DESCRIPTION

[0025] The following will be combined with the attached embodiment of the utility model Figure 1-4 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0026] A box gluing machine capable of adjusting the speed of cardboard movement comprises a frame 1, gluing devices 2 are arranged at both ends of one side of the top of the frame 1, a mounting plate 3 is fixedly installed on the inner side of the gluing device 2, a gear 4 and a hand wheel 7 are rotatably installed on both ends of one side of the mounting plate 3, a gear 2 5 is fixedly installed on one side of the gear 1 4, a gear 3 6 is fixedly installed on one side of the hand wheel 7, an adjusting frame 8 is penetrated on one side of the top of the gluing device 2, and a toothed plate 9 meshing with the gear 1 4 is fixedly connected to one side of the adjusting frame 8.

[0027] The specific use process is as follows: first, inject glue into the gluing device 2. It should be noted that a rubber roller is also provided in the gluing device 2 for leading out the glue, and the rubber roller is adapted to the pressure roller 11. The cardboard will pass over the rubber roller, that is, the cardboard passes between the pressure roller 11 and the rubber roller. This is the prior art and will not be described in detail in the text. The cardboard is fed in from the side where the conveying roller 16 is provided, and then, under the transfer of the conveying roller 16, the conveying roller 2 17, the conveying roller 3 18 and the two conveyor belts, it will pass between the pressure roller 11 and the rubber roller. At this time, the rubber roller will bring out the glue in the gluing device 2 and coat it on the cardboard, and under the rotation of the pressure roller 11, the cardboard will also send the cardboard coated with glue to the next process to avoid cardboard being blocked in the machine. When the cardboard is too thick, it is difficult to smoothly deliver the cardboard due to the distance between the pressure roller 11 and the glue roller, and it will also cause uneven glue coating on the surface of the cardboard. At this time, the user can turn the hand wheel 7, and the hand wheel 7 will drive the gear three 6 to rotate, and the gear three 6 will drive the gear two 5 to rotate through the chain, and the gear two 5 will drive the gear one 4 to rotate, and the gear one 4 will drive the tooth plate 9 to move up, and the tooth plate 9 will drive the adjusting frame 8 up, wherein, when the adjusting frame 8 moves and adjusts, the limit slider 12 will also move with the adjusting frame 8, and the limit slider 12 also slides in the limit slide groove 13, so that the movement of the adjusting frame 8 can be limited under the cooperation of the limit slider 12 and the limit slide groove 13, thereby ensuring the stability of the adjusting frame 8 when moving and adjusting, and providing users with a good working environment. The whole positioning assembly 14 will also move along with the movement of the adjusting frame 8, and the positioning pin 142 will first move out of the corresponding positioning hole 15 and compress the spring 143 as the adjusting frame 8 moves, and then move to the next positioning hole 15 in the process of movement, and snap into the current positioning hole 15 under the push of the spring 143, and then move out of the current positioning hole 15 and snap into the next positioning hole 15 again until the adjusting frame 8 stops moving after adjustment. At this time, under the push of the spring 143, the positioning pin 142 will snap into the positioning hole 15 at the current position, so as to realize the positioning of the adjusting frame 8 and the positioning of the working position of the pressure roller 11, which provides convenience for the user's work and use. The adjusting frame 8 moves up, and the stepper motor 10 and the pressure roller 11 installed on the adjusting frame 8 also move up, so that the distance between the pressure roller 11 and the glue roller will be expanded. During the adjustment process, it is necessary to constantly observe whether the glue on the surface of the cardboard is evenly coated. After the adjustment of the adjusting frame 8 is completed, the pressure roller 11 will be positioned at the current position under the action of the positioning component 14, and then when the cardboard continues to move, the stepper motor 10 will drive the pressure roller 11 to rotate, and the pressure roller 11 will press the cardboard down. This is based on the adjustment height of the pressure roller 11, that is, this is related to the distance between the pressure roller 11 and the cardboard. As the distance between the pressure roller 11 and the cardboard decreases, the friction between the pressure roller 11 and the cardboard will also increase, and it will be greater than the friction between the two conveyor belts and the cardboard, and the pressure roller 11 is also rotating.Therefore, the cardboard can be pushed out quickly. At this time, the moving speed of the cardboard is fast. On the contrary, the distance between the pressing roller 11 and the cardboard becomes larger, and the friction will be weakened. At this time, the friction is less than that of the two conveyor belts. Therefore, the cardboard can only be sent out at the speed of the two conveyor belts. This provides users with more and more flexible options for work and provides convenience for users.

[0028] Therefore, a structural design that can adjust the moving speed of the cardboard is adopted, so that the moving speed and the discharging speed of the cardboard can be switched between fast and slow. In this way, cardboards of different thicknesses can be moved at the speed set by the user during transfer, ensuring the uniformity of glue distribution when gluing the cardboard, avoiding the situation that the cardboards are not bonded together due to uneven glue distribution when the carton is formed, improving the processing quality of the carton, and providing convenience for users' work.

[0030] Specifically, with the setting of the limit slider 12 and the limit slot 13, when the adjusting frame 8 moves and adjusts, the limit slider 12 will also move with the adjusting frame 8, and at the same time, the limit slider 12 also slides in the limit slot 13. In this way, with the cooperation of the limit slider 12 and the limit slot 13, the movement of the adjusting frame 8 can be limited, thereby ensuring the stability of the adjusting frame 8 when moving and adjusting, and providing convenience for the user's work.

[0031] A stepper motor 10 located above the gluing device 2 is fixedly mounted on the top of the adjustment frame 8 , and a pressure roller 11 is fixedly mounted on the output shaft of the stepper motor 10 .

[0032] Specifically, the stepper motor 10 and the pressure roller 11 are arranged such that during the cardboard transmission process, the stepper motor 10 will drive the pressure roller 11 to rotate, and the pressure roller 11 will press down the cardboard, which is based on the adjustment height of the pressure roller 11, that is, this is related to the distance between the pressure roller 11 and the cardboard. As the distance between the pressure roller 11 and the cardboard decreases, the friction between the pressure roller 11 and the cardboard will also increase, and will be greater than the friction between the two conveyor belts and the cardboard, and the pressure roller 11 is also rotating, so the cardboard can be pushed out quickly, and the movement speed of the cardboard is fast at this time. On the contrary, if the distance between the pressure roller 11 and the cardboard becomes larger, the friction will be weakened, and at this time the friction is less than that of the two conveyor belts, so the cardboard can only be sent out at the speed of the two conveyor belts, thus providing users with more and more flexible choices for their work and providing convenience for their work.

[0033] A plurality of positioning holes 15 equidistantly spaced from top to bottom are provided at one end of the inner side of the gluing device 2, a positioning assembly 14 matched with the positioning holes 15 is provided at the bottom of one side of the adjusting frame 8, the positioning assembly 14 comprises a bracket 141 fixedly connected to the adjusting frame 8, a positioning pin 142 matched with the positioning hole 15 is penetrated through one side of the bracket 141, a spring 143 located on the outside of the bracket 141 is sleeved on the surface of the positioning pin 142, and both ends of the spring 143 are fixedly connected to the bracket 141 and the positioning pin 142, respectively.

[0034] Specifically, the positioning assembly 14 and the positioning hole 15 are arranged so that when the adjusting frame 8 moves, the entire positioning assembly 14 will also move therewith, and as the adjusting frame 8 moves, the positioning pin 142 will first move out of the corresponding positioning hole 15, compressing the spring 143 at the same time, and then move to the next positioning hole 15 during the movement, and be inserted into the current positioning hole 15 under the push of the spring 143, and then move out of the current positioning hole 15, and be inserted into the next positioning hole 15 again, until the adjusting frame 8 is adjusted and no longer moves, at this time, under the push of the spring 143, the positioning pin 142 will be inserted into the positioning hole 15 at the current position, so as to realize the positioning of the adjusting frame 8 and the positioning of the working position of the pressure roller 11, providing convenience for the user's work.

The conveying roller 2 17 is connected to the conveying roller 16 through a conveyor belt 1, and the two conveying rollers 3 18 are connected to the conveying roller 16 through a conveyor belt 2.

[0036] Specifically, the arrangement of the conveyor roller 1 16, the conveyor roller 2 17 and the conveyor roller 3 18 is such that when the machine is working, the conveyor roller 1 16, the conveyor roller 2 17 and the conveyor roller 3 18 will rotate simultaneously and in the same direction, so that in cooperation with the conveyor belt 1 and the conveyor belt 2, the cardboard can be conveyed, providing convenience for the user's work.
