Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box pasting technology, and in particular to a semi-automatic cardboard box pasting machine. Background Technology

[0002] The corrugated carton gluing equipment consists of a mounting frame, a first conveyor roller, a first conveyor belt, a second conveyor roller, a second conveyor belt, a hot press roller, a coating roller, a metering roller, and a pressure roller. When using the gluing production equipment, the first conveyor roller and the first conveyor belt on the mounting frame transport the printed face paper, while the second conveyor roller and the second conveyor belt transport the corrugated carton shell. Then, the coating roller, the metering roller, and the pressure roller apply adhesive to the top of the corrugated carton shell. The upper and lower conveyor belts then simultaneously press and laminate the material. Finally, the hot press roller instantly heats the material to accelerate the gelation of the adhesive layer before conveying it out.

[0003] The inventors discovered in their daily work that when using laminating production equipment, the adhesive on the surface of the coating roller may fall onto the pressure roller due to gravity. This causes the pressure roller to come into contact with the bottom of the corrugated cardboard and apply adhesive. To prevent the pressure roller from applying adhesive to the bottom of the corrugated cardboard, a water supply box is usually installed under the pressure roller, and the pressure roller is rotated in water for cleaning. However, this simple cleaning method cannot effectively remove the adhesive from the surface of the pressure roller, which may result in adhesive residue on the surface of the pressure roller, causing it to be applied to the bottom of the corrugated cardboard and have an impact. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in actual use, the glue on the surface of the coating roller may fall onto the pressure roller due to gravity, thus causing the pressure roller to come into contact with the bottom of the corrugated cardboard and apply glue. To prevent the pressure roller from applying glue to the bottom of the corrugated cardboard, a water supply box is usually installed under the pressure roller, and the pressure roller rotates in water for cleaning. However, this simple cleaning cannot effectively remove the glue from the surface of the pressure roller, which may result in glue remaining on the surface of the pressure roller and causing it to be applied to the bottom of the corrugated cardboard, thus affecting the product. Therefore, a semi-automatic carton gluing machine for packaging cartons is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a semi-automatic carton gluing machine, comprising a mounting frame, wherein a first conveyor belt, a second conveyor belt, and a rotatable first conveyor roller and a second conveyor roller are mounted between the two ends of the mounting frame, and a rotatable hot press roller, a coating roller, a metering roller, and a pressure roller are mounted between the two ends of the mounting frame, wherein a water supply box is fixedly connected between the two ends of the mounting frame, and a cleaning assembly is provided on the inner wall of the water supply box, wherein the cleaning assembly includes a hollow rotating rod rotatably connected between the two ends of the mounting frame by means of bearings, wherein bristles are inserted into the arc surface of the hollow rotating rod, and a motor is mounted at one end of the mounting frame, wherein the motor controls the rotation of the hollow rotating rod.

[0006] The effect achieved by the above components is as follows: when cleaning the pressure roller, the motor is started by the controller. The motor is connected to the cavity rotating rod through the reducer and coupling, so that the bristles on the cavity rotating rod rotate in the opposite direction to the rotation of the pressure roller. At the same time, the pressure roller is in the water in the water supply box, so that the bristles clean the glue on the pressure roller, thereby achieving the cleaning effect of the pressure roller as much as possible.

[0007] Preferably, the inner wall of the cavity rotating rod is provided with a mounting rod, the mounting rod is fixed to the brush bristles, and a first spring is fixedly connected between the mounting rod and the cavity rotating rod.

[0008] The effect achieved by the above components is as follows: through the mounting rod and the first spring, the bristles come into contact with the pressure roller, so that the first spring is in a compressed state, and its reverse force pushes the mounting rod, thus preventing the bristles from not contacting the pressure roller due to wear.

[0009] Preferably, a rectangular rod is inserted into one end of the water supply box, and a scraper is fixedly connected to one end of the rectangular rod.

[0010] The effect achieved by the above components is to remove the glue from the pressure roller by setting up a rectangular bar and a scraper.

[0011] Preferably, one end of the rectangular rod is fixedly connected to a second spring, and the other end of the second spring is fixed to the water supply box.

[0012] The effect achieved by the above components is that by setting the first spring and the second spring to pull the rectangular rod, the scraper bar and the pressure roller are in full contact.

[0013] Preferably, one end of the mounting bracket is fixedly connected to a drain head, and the other end of the drain head is provided with a connecting assembly. The connecting assembly includes a connecting ring fixedly connected to the arc surface of the drain head, a connecting head slidably connected to the inner wall of the connecting ring, a drain pipe fixedly connected to the left end of the connecting head, and a positioning pin slidably inserted into the inner wall of the connecting ring, the positioning pin being inserted into the drain head.

[0014] The effect achieved by the above components is as follows: by pulling the mechanism, the positioning pin is retracted into the connecting ring, the reset mechanism is compressed, the connecting head is inserted into the connecting ring, the pulling mechanism is released, the reset mechanism is reset, the positioning pin is inserted into the drain head, thereby fixing the drain pipe, and then the drain pipe valve is opened to drain the wastewater in the water supply box.

[0015] Preferably, a pull rope is fixedly connected to the upper end of the positioning pin, and the pull rope passes through the connecting ring.

[0016] The effect achieved by the above components is that pulling the pull rope causes the positioning pin to retract into the connecting ring.

[0017] Preferably, a third spring is fixedly connected to the upper end of the positioning pin, and the other end of the third spring is fixed to the connecting ring.

[0018] The effect achieved by the above components is that pulling the pull rope causes the positioning pin to retract into the connecting ring, thereby compressing the third spring.

[0019] Preferably, a sealing ring is provided between the connector and the drain head.

[0020] The effect achieved by the above components is to seal the connector and drain head by setting a sealing ring.

[0021] In summary, the beneficial effects of this utility model are as follows: In this invention, when the cleaning component is set up, the motor is started by the controller when cleaning the pressure roller. The motor is connected to the cavity rotating rod through the reducer and coupling, causing the bristles on the cavity rotating rod to rotate in the opposite direction to the rotation of the pressure roller. At the same time, the pressure roller is in the water of the water supply box, so that the bristles clean the glue on the pressure roller, thereby achieving the cleaning effect of the pressure roller as much as possible. This solves the problem that the glue on the surface of the coating roller may fall onto the pressure roller due to gravity, and thus the pressure roller may come into contact with the bottom of the corrugated cardboard and apply glue. In order to avoid the pressure roller applying glue to the bottom of the corrugated cardboard, a water supply box is usually set under the pressure roller, and the pressure roller rotates in the water for cleaning. However, this simple cleaning cannot effectively remove the glue from the surface of the pressure roller, which may result in glue remaining on the surface of the pressure roller and being applied to the bottom of the corrugated cardboard, causing problems.

[0029] Reference Figure 1 and Figure 2 as well as Figure 3 As shown, this utility model provides a technical solution: a semi-automatic carton gluing machine includes a mounting frame 1. A first conveyor belt 4, a second conveyor belt 6, a rotatable first conveyor roller 5, and a second conveyor roller 7 are installed between the two ends of the mounting frame 1. A rotatable hot press roller 10, a coating roller 8, a metering roller 9, and a pressure roller 13 are installed between the two ends of the mounting frame 1.

[0030] Reference Figure 3 and Figure 4As shown, in this embodiment: the cleaning component 2 includes a hollow rotating rod 21 rotatably connected between the two ends of the mounting frame 1 via bearings. Brush bristles 22 are inserted into the arc surface of the hollow rotating rod 21. A motor 11 is mounted on one end of the mounting frame 1, controlling the rotation of the hollow rotating rod 21. When the cleaning component 2 is set up, the motor 11 is started by the controller when cleaning the pressure roller 13. The motor 11 is connected to the hollow rotating rod 21 via a reducer and a coupling, causing the brush bristles 22 on the hollow rotating rod 21 to rotate in the opposite direction to the rotation of the pressure roller 13. Simultaneously, the pressure roller 13 is submerged in water in the water supply box 15, allowing the brush bristles 22 to clean the glue on the pressure roller 13, thereby achieving the desired cleaning effect. An mounting rod 23 is provided on the inner wall of the hollow rotating rod 21. The mounting rod 23 and... The brush bristles 22 are fixed, and a first spring 24 is fixedly connected between the mounting rod 23 and the cavity rotating rod 21. Through the mounting rod 23 and the first spring 24, the brush bristles 22 contact the pressure roller 13, so that the first spring 24 is in a compressed state. Its reverse force pushes the mounting rod 23, so as to prevent the brush bristles 22 from not contacting the pressure roller 13 due to wear. A rectangular rod 26 is inserted into one end of the water supply box 15. A scraper 25 is fixedly connected to one end of the rectangular rod 26. By setting the rectangular rod 26 and the scraper 25, the glue on the pressure roller 13 is scraped off. A second spring 27 is fixedly connected to one end of the rectangular rod 26. The other end of the second spring 27 is fixed to the water supply box 15. By setting the first spring 24 and the second spring 27, the rectangular rod 26 is pulled, so that the scraper 25 is in full contact with the pressure roller 13.

[0031] Reference Figure 2 and Figure 5As shown in this embodiment: a drain head 12 is fixedly connected to one end of the mounting bracket 1, and a connecting component 3 is provided at the other end of the drain head 12. The connecting component 3 includes a connecting ring 33 fixedly connected to the arc surface of the drain head 12. A connecting head 31 is slidably connected to the inner wall of the connecting ring 33. A drain pipe 32 is fixedly connected to the left end of the connecting head 31. A positioning pin 34 is slidably inserted into the inner wall of the connecting ring 33. The positioning pin 34 is inserted into the drain head 12. By pulling the mechanism, the positioning pin 34 is retracted into the connecting ring 33, which compresses the reset mechanism and drags the connecting head 31 into the connecting ring 33. Releasing the pulling mechanism resets the reset mechanism, allowing the positioning pin 34 to be inserted into the drain head 12. The drain head 12 is inserted into the drain pipe 32 to fix the drain pipe 32. Then, the valve of the drain pipe 32 is opened to drain the wastewater in the water supply box 15. The upper end of the positioning pin 34 is fixedly connected to the pull rope 36, which passes through the connecting ring 33. Pulling the pull rope 36 causes the positioning pin 34 to retract into the connecting ring 33. The upper end of the positioning pin 34 is fixedly connected to the third spring 35, and the other end of the third spring 35 is fixed to the connecting ring 33. Pulling the pull rope 36 causes the positioning pin 34 to retract into the connecting ring 33, which compresses the third spring 35. A sealing ring 37 is provided between the connector 31 and the drain head 12 to seal the connector 31 and the drain head 12.

[0032] Working principle: When using the laminating production equipment (model 1880 is optional), the pre-lamination preparation stage is as follows: the single-sided corrugated substrate is preheated by rollers to adjust the moisture content and eliminate curling stress; the printed face paper is aligned by a correction device to ensure straight, tear-free gripper edges; the starch adhesive viscosity is adjusted to 45-60 seconds; and the coating temperature needs to be maintained at 60±5℃ to ensure fluidity. The core lamination process involves the first conveyor roller 5 and the first conveyor belt 4 on the mounting frame 1 conveying the printed face paper in conjunction with the auxiliary plate 14; the second conveyor roller 7 and the second conveyor belt 6 convey the corrugated carton shell; and then the coating roller 8 and... Measuring roller 9 and pressure roller 13 apply adhesive to the top of the corrugated cardboard shell, then the upper and lower conveyor belts simultaneously press and laminate it. Next, hot press roller 10 instantly heats and accelerates the adhesive gelation, then conveys it out. Post-curing and quality inspection: the laminated cardboard needs 48 hours of natural drying, with a compressive strength loss rate ≤10% and an edge misalignment between the face paper and the corrugated cardboard ≤0.5mm. When cleaning pressure roller 13, motor 11 is started via controller. Motor 11 is connected to the cavity rotating rod 21 via a reducer and coupling, causing the bristles 22 on the cavity rotating rod 21 to rotate in the same direction as the pressure roller. The pressure roller 13 rotates in the opposite direction, and is simultaneously submerged in water in the water supply box 15. This allows the bristles 22 to clean the adhesive on the pressure roller 13, thereby maximizing its cleaning effect. Through the mounting rod 23 and the first spring 24, the bristles 22 contact the pressure roller 13, causing the first spring 24 to be compressed. Its reverse force pushes the mounting rod 23, preventing the bristles 22 from losing contact with the pressure roller 13 due to wear. The rectangular rod 26 and scraper 25 are used to scrape off the adhesive on the pressure roller 13. The first spring 26... 4. The second spring 27 pulls the rectangular rod 26, making the scraper 25 fully contact the pressure roller 13, pulling the pull rope 36, causing the positioning pin 34 to retract into the connecting ring 33, compressing the third spring 35, dragging the connector 31 into the connecting ring 33, releasing the pull rope 36, causing the third spring 35 to reset, and causing the positioning pin 34 to insert into the drain head 12, thereby fixing the drain pipe 32. Then, the valve of the drain pipe 32 is opened to drain the wastewater in the water supply box 15. The connector 31 and the drain head 12 are sealed by setting the sealing ring 37.
