Description

Technical Field

[0001] The invention relates to the technical field of carton production, and in particular to a cardboard bonding device and process for producing corrugated carton. Background Art

[0002] Corrugated cardboard is a common material for paper packaging boxes. In the process of corrugated box production, the processed corrugated cardboard needs to be glued to obtain a usable corrugated box. When producing corrugated boxes, it is necessary to evenly apply glue on the top of the edge of the unfolded corrugated cardboard near one side, and then glue the ends together, open it, and seal the bottom to form a corrugated box to be used.

[0003] The Chinese patent application No. 202411237189.6 discloses a corrugated box production cardboard bonding device, which is provided with a boss group including a plurality of columnar bosses, and the diameter increment between two adjacent columnar bosses is equal to the thickness of the corrugated cardboard to be processed. The corrugated cardboard is arranged on a frame, and the frame can rotate relative to the base, so that the corrugated cardboard slides along the tilt direction of the frame until it is received by the corresponding columnar boss, forming a staggered state. However, this technical solution still has the following defects:

[0004] 1. Although it is convenient to stagger a group of corrugated cardboards in sequence, it is inconvenient to automatically and evenly apply glue to the staggered corrugated cardboards, which affects the gluing efficiency;

[0005] 2. It is necessary to frequently adjust the height of the boss group using the distance adjustment unit, and after each height adjustment, it is necessary to ensure that the upper end of the stacked corrugated cardboard is flush with the uppermost end of the boss group, which can easily affect work efficiency.

[0021] Step 3: Use the gravity traction mechanism to pull the bearing plate upward, start the feeding mechanism, and the stacked corrugated cardboard can be sequentially conveyed into the U-shaped plate. Use the glue application mechanism to apply glue to the top edge of one side of the corrugated cardboard.

[0022] Step 4: After gluing the head and tail of the corrugated cardboard and spreading it out, then seal the bottom to form a corrugated cardboard box ready for use.

[0023] Advantages of the present invention:

[0024] 1. In the present invention, by adjusting the vertical distance between the bottom of the feeding mechanism and the top of the limiting member to adapt it to the thickness of the corrugated cardboard to be coated with glue, and cooperating with the blocking effect of the limiting member, when the uppermost corrugated cardboard is conveyed and advanced, the other corrugated cardboards will not be displaced, enabling the corrugated cardboards to advance in an orderly manner one by one. At the same time, the top of the limiting member is used to conveniently support part of the conveyed corrugated cardboard, facilitating the transition of the corrugated cardboard to the guiding mechanism.

[0025] 2. In the present invention, the gravity traction mechanism is used to conveniently apply a continuously upward pulling force to the bearing plate, which not only facilitates driving the bearing plate and the stacked corrugated cardboards to rise, but also enables the uppermost corrugated cardboard to automatically adhere to the feeding mechanism. Cooperating with the feeding mechanism, it is convenient to convey the stacked corrugated cardboards to the guiding mechanism one by one. In addition, the gravity traction mechanism can also be reset by changing the gravity, thereby facilitating the lifting of the subsequent corrugated cardboards to be coated with glue.

[0026] 3. In the present invention, the guiding mechanism not only conveniently guides and conveys the corrugated cardboard, but also is convenient to adjust correspondingly according to the size of the corrugated cardboard. The guided and conveyed corrugated cardboard will not be displaced under the limiting effect. In addition, the guiding mechanism is also convenient to uniformly and automatically apply glue to the top edge on one side of the corrugated cardboard, thereby effectively improving the glue coating efficiency of the corrugated cardboard, and further facilitating the improvement of the production efficiency of the corrugated cardboard box.

[0027] 4. In the present invention, after the feeding mechanism and the guiding mechanism are correspondingly adjusted according to the specific size and thickness of the corrugated cardboard, as long as the size and thickness of the corrugated cardboard to be coated with glue do not change, no adjustment operation is required during the subsequent processing, thereby effectively reducing the number of adjustments and facilitating the improvement of work efficiency.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] As shown Figures 1-9 in the figure, the present invention is a corrugated cardboard production cardboard bonding device, including a base 1, and a processing mechanism 3 for applying glue to the corrugated cardboard 2 is installed on the base 1; the processing mechanism 3 includes a bearing plate 31, an inverted L-shaped plate 32, a gravity traction mechanism 33, a limiting member 34, a feeding mechanism 35 and a guiding mechanism 36. The inverted L-shaped plate 32 is installed on the top of the base 1 near one side. The corrugated cardboard 2 is stacked on the bearing plate 31. The bearing plate 31 is connected to the inverted L-shaped plate 32 through the gravity traction mechanism 33. The feeding mechanism 35 movably penetrates through the top of the inverted L-shaped plate 32. The limiting member 34 is installed on the top of the base 1. The limiting member 34 is used to transition the uppermost corrugated cardboard 2 to the guiding mechanism 36 and limit the positions of the remaining corrugated cardboard 2. The guiding mechanism 36 is located on one side of the base 1, and the guiding mechanism 36 is used to guide and convey the corrugated cardboard 2 and apply glue to the top edge of one side thereof.

[0041] It should be noted that during use, the height of the feeding mechanism 35 is adjusted correspondingly according to the thickness of a single corrugated cardboard 2 stacked on the bearing plate 31, so that the vertical distance between the bottom of the feeding mechanism 35 and the top of the limiting member 34 is equal to the thickness of a single corrugated cardboard 2. The position of the limiting member 34 is adjusted to make it fit the stacked corrugated cardboard 2 (the stacking height of the corrugated cardboard 2 does not exceed the height of the limiting member 34). The gravity traction mechanism 33 is used to apply a continuously upward pulling force to the bearing plate 31, so that the uppermost corrugated cardboard 2 can automatically stick tightly to the feeding mechanism 35. Starting the feeding mechanism 35 can sequentially transition the corrugated cardboard 2 to the guiding mechanism 36 through the limiting member 34. The guiding mechanism 36 is used to limit and convey the corrugated cardboard 2, and uniformly apply glue to the top edge of one side thereof during the conveying process, greatly improving the glue application efficiency, thereby improving the production efficiency of the corrugated cardboard box.

[0042] As shown Figures 1-3 in the figure, the gravity traction mechanism 33 includes a water tank 331, a first guide wheel 332, a second guide wheel 333, a suspension rope 334, an extension seat 335, a guide rod 336 and a water supply and drainage mechanism 337. The two guide rods 336 are symmetrically arranged on the top of the base 1 near one side. The bearing plate 31 is slidably sleeved with the guide rod 336. The extension seat 335 is installed on one side of the inverted L-shaped plate 32 near the top. The first guide wheel 332 and the second guide wheel 333 are respectively arranged on the top of the inverted L-shaped plate 32 and the extension seat 335. One end of the suspension rope 334 is connected to the water tank 331, and the other end of the suspension rope 334 sequentially bypasses the second guide wheel 333 and the first guide wheel 332 and is connected to the bearing plate 31. The base 1 is connected to the water tank 331 through the water supply and drainage mechanism 337.

[0043] It should be noted that when the water tank 331 is empty, its weight is less than that of the bearing plate 31. By injecting water into the water tank 331 to increase the weight, with the cooperation of the first guide wheel 332, the second guide wheel 333 and the lifting rope 334, it is convenient to pull the bearing plate 31 and the stacked corrugated paperboards 2 upward. As long as the total weight of the water tank 331 and the water inside is significantly greater than the total weight of the bearing plate 31 and the stacked corrugated paperboards 2, the topmost corrugated paperboard 2 can be automatically pressed against the bottom of the feeding mechanism 35.

[0044] As Figure 3 and Figure 5 shown, the feeding mechanism 35 includes a housing 351, a feeding roller 352, a motor 353 and a regulating component 354. A notch for the housing 351 to pass through is formed through the top of the inverted L-shaped plate 32. The feeding roller 352 is rotatably installed in the housing 351, and the bottom of the feeding roller 352 extends to the outside of the housing 351. The motor 353 is installed at one end of the housing 351 and is used to drive the feeding roller 352 to rotate. The regulating component 354 is installed on the top of the inverted L-shaped plate 32, and the regulating component 354 is used to adjust the lifting of the housing 351.

[0045] It should be noted that in the initial state, the bottom of the feeding roller 352 is flush with the top of the limiting member 34. It is only necessary to use the regulating component 354 to adjust the rising distance of the housing 351 to be equal to the thickness of the corrugated paperboard 2 to be coated with glue. That is to say, ensure that only a single corrugated paperboard 2 can pass between the feeding roller 352 and the limiting member 34. The remaining corrugated paperboards 2 will be blocked by the limiting member 34 when the topmost corrugated paperboard 2 is being conveyed, ensuring that the corrugated paperboards 2 can be conveyed in sequence and orderly during the conveying process.

[0046] As Figure 2 and Figure 4 shown, the water supply and drainage mechanism 337 includes a pump body 3371, a hose 3372, a corrugated pipe 3373, an L-shaped pipe 3374 and a drain pipe 3375 with a valve. The pump body 3371 is installed on the outer side wall of the base 1 near the bottom. The pump body 3371 conveys the water in the base 1 to the water tank 331 through the hose 3372. The drain pipe 3375 is installed at the bottom of the water tank 331. The L-shaped pipe 3374 is installed on one side of the base 1. The drain pipe 3375 and the L-shaped pipe 3374 are connected through the corrugated pipe 3373.

[0047] It should be noted that starting the pump body 3371 can cooperate with the hose 3372 to inject the water stored in the base 1 into the water tank 331 to increase the weight. When the corrugated paperboards 2 on the bearing plate 31 need to be reset after being conveyed, opening the valve on the drain pipe 3375 can lead the water in the water tank 331 into the base 1, thereby realizing the reset.

[0048] As Figure 1 and Figure 5As shown, the regulation component 354 includes a first screw rod 3541, a threaded sleeve 3542, a scale slider 3543, and a measuring guide rod 3544 with scale lines. The first screw rod 3541 is rotatably connected to the top of the inverted L-shaped plate 32. The threaded sleeve 3542 is installed at one end of the housing 351 and is threadedly connected to the first screw rod 3541. The scale slider 3543 is installed on one side of the housing 351 near the top. The measuring guide rod 3544 is installed on the top of the inverted L-shaped plate 32. The scale slider 3543 is slidably sleeved on the measuring guide rod 3544.

[0049] It should be noted that by rotating the first screw rod 3541, the housing 351 drives the scale slider 3543 to rise along the measuring guide rod 3544. The scale numbers on the measuring guide rod 3544 are used to accurately determine the rising distance until the confirmed rising distance is equal to the thickness of the corrugated cardboard 2.

[0050] As Figure 1 and Figure 6 As shown, the guiding mechanism 36 includes a U-shaped plate 362 with a bracket 361, a rotating roller 363, a deflecting rod 364, a guiding plate 365, a gluing mechanism 366, and a second screw rod 367. The bracket 361 is installed at the bottom of the U-shaped plate 362. A plurality of rotating rollers 363 are rotatably installed between the U-shaped plates 362. The guiding plate 365 is movably sleeved on the rotating roller 363. The second screw rod 367 penetrates through the side wall of the U-shaped plate 362 and is rotatably connected to the guiding plate 365. The gluing mechanism 366 is installed on one of the guiding plates 365. A deflecting groove is opened at one end of the U-shaped plate 362 close to the limiting member 34. One end of the deflecting rod 364 is rotatably connected to the bottom of the deflecting groove through a damping shaft.

[0051] It should be noted that the plurality of rotating rollers 363 can achieve synchronous rotation through a sprocket, a chain, and their driving motor (not shown in the figure). This is prior art and will not be elaborated here. The top of the rotating roller 363 is flush with the top of the limiting member 34. The side of the deflecting rod 364 away from the bottom of the deflecting groove is flush with the side of the guiding plate 365 away from the second screw rod 367. After the corrugated cardboard 2 is neatly stacked on the bearing plate 31, rotate the deflecting rod 364 to approach the corrugated cardboard 2, and then rotate the second screw rod 367 to adjust the position of the guiding plate 365 until the deflecting rod 364 can be attached to the side of the corrugated cardboard 2, so as to ensure that the distance between the two guiding plates 365 is just enough for the corrugated cardboard 2 to pass through.

[0052] As Figures 6-7As shown in the figure, the glue - applying mechanism 366 includes a fixing plate 3661, an electric push rod 3662, a glue - applicator 3663, a glue - applying roller 3664 and a glue supply pipe 3665. The fixing plate 3661 is installed on the top of the guiding plate 365. The glue - applicator 3663 is slidably connected to the side wall of the guiding plate 365. The electric push rod 3662 is installed on the top of the fixing plate 3661, and the output end of the electric push rod 3662 is connected to the top of the glue - applicator 3663. The glue - applying roller 3664 is rotatably installed in the glue - applicator 3663, and the glue supply pipe 3665 is connected to the top of the glue - applicator 3663.

[0053] It should be noted that the glue supply pipe 3665 is connected to an external glue - supply device. The electric push rod 3662 facilitates controlling the contact between the glue - applying roller 3664 and the corrugated cardboard 2 being guided and conveyed. During the conveying process, the glue - applying roller 3664 is driven to rotate by the frictional force, thereby realizing the automatic and uniform glue - applying to the corrugated cardboard 2.

[0054] As Figures 6-9 shown in the figure, a third screw rod 4 is penetratively arranged on the bracket 361. The third screw rod 4 is rotatably connected to one side of the limiting member 34. A U - shaped notch 311 for the movement of the limiting member 34 is formed on the bearing plate 31. A T - shaped slider 341 is installed at the bottom of the limiting member 34, and a T - shaped sliding groove 11 for the T - shaped slider 341 to slide is formed on the top of the base 1.

[0055] It should be noted that rotating the third screw rod 4 can make the limiting member 34 drive the T - shaped slider 341 at its bottom end to slide along the T - shaped sliding groove 11, thereby facilitating the stable adjustment of the position of the limiting member 34.

[0056] As Figure 4 shown in the figure, a guiding sleeve 3311 is arranged on the side of the water tank 331 away from the inverted L - shaped plate 32. An L - shaped guiding column 12 is installed on one side of the base 1. The guiding sleeve 3311 is slidably sleeved with the L - shaped guiding column 12.

[0057] It should be noted that the L - shaped guiding column 12 facilitates the sliding guidance of the guiding sleeve 3311, so that the water tank 331 will not shake during the lifting process, thereby ensuring stability.

[0058] The embodiment of the present invention provides a corrugated cardboard bonding process for corrugated carton production, including the following steps:

[0059] Step 1: Neatly stack the corrugated cardboard 2 on the bearing plate 31, and ensure that the total height of the corrugated cardboard 2 does not exceed the height of the limiting member 34. Subsequently, adjust the position of the limiting member 34 so that it fits against one side of the corrugated cardboard 2.

[0060] Step 2: Adjust the height of the feeding mechanism 35 according to the thickness of the single corrugated paperboard 2, so that the vertical distance between the bottom of the feeding mechanism 35 and the top of the limiting member 34 is equal to the thickness of the single corrugated paperboard 2, and adjust the position of the guide plate 365 until the deflection rod 364 fits the side wall of the corrugated paperboard 2;

[0061] Step 3: Use the gravity traction mechanism 33 to pull the carrier plate 31 upward, start the feeding mechanism 35 to sequentially convey the stacked corrugated paperboards 2 into the U-shaped plate 362, and use the gluing mechanism 366 to apply glue to the top edge of one side of the corrugated paperboard 2;

[0062] Step 4: Glue the glued corrugated cardboard 2 at the ends and then stretch them apart, and then seal the bottom to form a corrugated box to be used.

[0063] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
