Description

Technical Field

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

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. Cardboard boxes commonly have three or five layers, while seven-layer boxes are less common. Each layer consists of linerboard, corrugated paper, core paper, and face paper. Linerboard and face paper can be made of kraft paper or kraft paper, while the core paper is made of corrugated paper. The colors and textures of different types of paper are different, and the paper produced by different manufacturers is also different.

[0003] In general, when applying glue to cardboard boxes, the glue rollers are fixed, which can only apply glue to cardboard boxes of a fixed width. This has relatively low applicability and cannot apply glue to cardboard boxes of different widths. Furthermore, the cardboard boxes may shift during the glue application process, affecting the glue application quality. Therefore, there is an urgent need for a cardboard box glue application device to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a gluing device for cardboard boxes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cardboard box gluing device includes a workbench, a mounting frame fixed to one end of the top of the workbench, a glue storage box at one end of the mounting frame, a fixing frame at one end of the glue storage box, and a gluing mechanism for applying glue to different sizes inside the fixing frame.

[0007] The gluing mechanism includes a first bidirectional lead screw rotatably connected to both sides of the inner wall of the fixed frame. Each of the two outer walls of the first bidirectional lead screw has a sliding block adapted to it. A glue outlet is fixed to the bottom of each of the two sliding blocks. A motor is installed on one side of the fixed frame, and the motor's output shaft is fixedly connected to one side of the first bidirectional lead screw. Second guide rods are fixed to both ends of the inner wall of the fixed frame, and holes for the second guide rods to pass through are opened at both ends of the sliding blocks. A clamping mechanism for pressing the carton is provided at the bottom of one end of the fixed frame. The first bidirectional lead screw can drive the two glue outlets closer together or further apart, enabling gluing operations on cartons of different sizes.

[0008] Preferably, a glue pump is installed at the bottom of the glue storage tank at the end away from the fixed frame. The glue inlet end of the glue pump is connected to and communicates with the inside of the glue storage tank through a conduit. The glue outlet end of the glue pump is connected to a glue delivery pipe. A fixed pipe is fixed at the bottom of the glue storage tank, and the other end of the glue delivery pipe is connected to and communicates with the outer surface of the fixed pipe. The other ends of the two glue outlets are each connected to the same connecting hose, and the other end of the connecting hose is connected to and communicates with the outer wall of the fixed pipe.

[0009] Preferably, the top of the glue storage tank is provided with a glue injection port that communicates with its interior.

[0010] Preferably, the clamping mechanism includes a fixed shell fixed to the bottom of one end of the fixed frame. A second bidirectional lead screw is rotatably connected to both sides of the inner wall of the fixed shell. Both outer walls of the second bidirectional lead screw are provided with matching sliding blocks. A fixing block is fixed to the bottom of each of the two sliding blocks. A sliding rod is provided below the fixing block, and a clamping block is fixed to the bottom of the sliding rod.

[0011] Preferably, the bottom of both fixing blocks is provided with a sliding groove adapted to the sliding rod, one end of a spring is fixed to the top of the pressing block, the other end of the spring is fixedly connected to the bottom of the fixing block, and the spring is located on the outer surface of the sliding rod. The pressing block can pre-press the two sides of the carton, and the spring can prevent the carton from being crushed.

[0012] Preferably, a knob is fixed to one side of the second bidirectional lead screw through the fixed housing.

[0013] Preferably, a first guide rod is fixed on both sides of the inner wall of the mounting frame. The bottom of the first guide rod is fixedly connected to the top of the workbench. A slider is slidably provided on the outer wall of the two first guide rods. The same connecting plate is fixed on the side of the two sliders that are close to each other. One end of the connecting plate is fixedly connected to the top of one end of the glue storage box. An electric push rod is installed on the top of the mounting frame. The output shaft of the electric push rod is fixedly connected to the top of the connecting plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Due to the adoption of a gluing mechanism, when it is necessary to apply glue to cartons of different sizes, the motor drives the first bidirectional lead screw to rotate, which in turn drives the two sliding blocks to move away from or towards each other, thereby achieving the effect of applying glue to cartons of different sizes. This increases the versatility and flexibility of the gluing equipment, reduces changeover time, and enables the equipment to complete the gluing of more cartons per unit time, significantly improving overall production efficiency.

[0016] 2. Due to the adoption of a clamping mechanism, turning the knob can drive the second bidirectional lead screw to rotate, which in turn can drive the two fixed blocks to move closer or further apart. Then, the fixed shell will move down with the fixed frame, which can drive the two clamping blocks to clamp the carton. The spring can keep the clamping blocks in a state of tension at all times, thus achieving the effect of initially clamping the carton of different sizes and preventing the carton from shifting during the glue application process, which would affect the glue application operation.

A fixed pipe 304 is fixed at the bottom of the glue storage tank 3, and the other end of the glue delivery pipe 302 is connected to and communicates with the outer surface of the fixed pipe 304. The other ends of the two glue outlets 306 are each connected to the same connecting hose 305, and the other end of the connecting hose 305 is connected to and communicates with the outer wall of the fixed pipe 304.

[0027] In this utility model, the top of the glue storage tank 3 is provided with a glue injection port that communicates with its interior.

[0028] In this utility model, the clamping mechanism includes a fixed shell 401 fixed to the bottom of one end of the fixed frame 301. The inner walls of the fixed shell 401 are rotatably connected to the two sides of the second bidirectional lead screw 403. The outer walls of the two sides of the second bidirectional lead screw 403 are provided with sliding blocks with sleeves that are adapted to it. The bottom of the two sliding blocks with sleeves is fixed with a fixing block 405. The bottom of the fixing block 405 is provided with a sliding rod 402. The bottom of the sliding rod 402 is fixed with a clamping block 4. The sliding blocks with sleeves are adapted to the internal size of the fixed shell 401 and limit its movement.

[0029] In this utility model, the bottom of the fixing block 405 is provided with a sliding groove that matches the sliding rod 402. One end of the spring 406 is fixed to the top of the pressing block 4. The other end of the spring 406 is fixedly connected to the bottom of the fixing block 405. The spring 406 is located on the outer surface of the sliding rod 402. The pressing block 4 can pre-press the two sides of the carton. The spring 406 can prevent the carton from being crushed.

[0030] In this utility model, a knob 404 is fixed to one side of the second bidirectional lead screw 403 through the fixed shell 401.

[0031] In this utility model, a first guide rod 202 is fixed on both sides of the inner wall of the mounting frame 2. The bottom of the first guide rod 202 is fixedly connected to the top of the workbench 1. A slider 203 is slidably provided on the outer wall of the two first guide rods 202. The same connecting plate 204 is fixed on the side of the two sliders 203 that are close to each other. One end of the connecting plate 204 is fixedly connected to the top of one end of the glue storage box 3. An electric push rod 201 is installed on the top of the mounting frame 2. The output shaft of the electric push rod 201 is fixedly connected to the top of the connecting plate 204.

[0032] Working principle: In use, first, place multiple cartons neatly on top of the workbench 1, with the area to be glued positioned below the glue dispensing head 306. Then, by operating the electric push rod 201, the electric push rod 201 pushes the connecting plate 204, causing it to move downwards. The connecting plate 204 then causes the slider 203 to slide along the outer wall of the first guide rod 202. The connecting plate 204 then causes the glue storage tank 3 to move downwards. The first guide rod 202 improves the stability of the movement of the glue storage tank 3. When the glue storage tank 3 moves downward, it will cause the fixed frame 301 to move downward, and bring the glue dispensing head 306 closer to the part of the cardboard that needs to be glued. Then, the glue pump 303 will extract the glue from the inside of the glue storage tank 3, and then deliver it to the fixed pipe 304 through the glue delivery pipe 302. Then, the fixed pipe 304 can deliver the glue to the connecting hose 305, and then to the glue dispensing head 306 to apply glue to the cardboard. When encountering cardboard boxes of different sizes, the running motor 307 will drive the... A double-acting screw 308 rotates, causing two sliding blocks 310 with sleeves to move closer or further apart, thus achieving the effect of applying glue to cartons of different sizes. By rotating the knob 404, the knob 404 will drive the second double-acting screw 403 to rotate, and then the second double-acting screw 403 will drive the two sliding blocks with sleeves to move closer or further apart, thus achieving the effect of pre-compressing cartons of different sizes. Since the glue application operation does not require the cartons to be too fixed, the spring 406 is used to initially compress the cartons to prevent the compression block 4 from damaging the cartons. The fixed shell 401 will move down with the fixed frame 301, and drive the compression block 4 to move down, and then approach the top of the cartons to compress them. The compression block 4 will drive the sliding rod 402 to slide in the groove at the bottom of the fixed block 405, thereby squeezing the spring 406. Through the characteristics of the spring 406, the compression block 4 will be squeezed, thereby achieving the initial compression of the cartons and completing the glue application operation.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
