Description

Technical Field

[0001] This utility model belongs to the field of paper packaging technology, and in particular relates to a paper packaging box gluing machine. Background Technology

[0002] In the packaging and printing industry, the application of box gluing machines is the final step in packaging box processing. It involves folding and gluing printed, die-cut cardboard into shape. Machine gluing replaces manual gluing, reducing labor costs and improving efficiency. The working principle of an automatic box gluing machine is as follows: after power is turned on, the entire conveyor belt begins to move. The die-cut semi-finished cardboard boxes are placed at the paper feed position of the gluing machine. The conveyor belt automatically feeds individual box sheets according to the pre-set paper feed guide on the paper stop frame into the middle conveyor belt (if the semi-finished cardboard boxes have undergone surface treatment such as lamination or varnishing, glue can be applied to the inner edges of the boxes simultaneously after entering the middle section). The conveyor belt then transports the boxes to the final gluing section for pressure packaging.

[0003] Comparing with Chinese Patent No. CN222819658U, a paper packaging box gluing machine is disclosed, including a gluing device and an auxiliary feeding device. The auxiliary feeding device includes a support base, a conveyor table, an inclined top plate mechanism, an auxiliary moving structure, and a lateral limiting structure. The inclined top plate mechanism includes a moving support structure, a first push motor, and a top material structure. The moving support structure is installed on the upper surface of one end of the support base, the first push motor is installed on the upper surface of one end of the moving support structure, and the top material structure is hinged to the outer surface of one end of the moving support structure. The first push motor and the top material structure are hinged together. The inclined top plate mechanism cooperates with the conveyor table to realize the function of dynamic adjustment during the conveying of paperboard raw materials. By adjusting the inclination angle of the paperboard raw materials, different degrees of friction are obtained to ensure that the paperboard raw materials can be stably conveyed when entering the gluing device, avoiding production failures and quality problems caused by improper angles.

[0004] However, the aforementioned patent directly uses a conveyor belt to rub the cardboard raw materials one by one for discharge. This is prone to causing the cardboard raw materials to become skewed due to uneven force, and it is also easy to cause damage by rubbing a layer of cardboard raw materials at the end. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this utility model is to provide a paper packaging box gluing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A paper packaging box gluing machine includes a main gluing body. A feeding device for stably conveying cardboard raw materials is provided on one side of the main gluing body. It also includes a storage device for stably storing the cardboard raw materials at the end of the feeding device away from the main gluing body. An adjustment device for slidingly adjusting the release of cardboard raw materials according to thickness is provided at the discharge end of the storage device. The feeding device includes a frame body with several conveyor belts evenly distributed on it. Each conveyor belt is driven by a rotary motor at one end. Feeding rollers are arranged between the conveyor belts, and each feeding roller is driven by a servo motor at one end. The machine is driven by a servo motor, and the bottom of the frame is provided with an auxiliary support component for support and adjustment. The storage device includes a storage box, with a discharge port at one end of the bottom of the storage box. A discharge plate for changing the inclination angle of the cardboard raw material is rotatably provided at the end of the bottom of the storage box away from the discharge port. An electric push rod is installed at the bottom of the discharge plate. Two positioning components for tightening and limiting are symmetrically arranged on both sides of the storage box. The adjustment device includes a height limit cover, with two limit sliding columns symmetrically arranged on both sides of the height limit cover. An anti-detachment plate is provided at the top of the limit sliding column, and a scale is provided on the surface of the limit sliding column.

[0008] Furthermore: the auxiliary support assembly includes two symmetrically arranged clearance holes on the frame body and a column provided on the bottom surface of the frame body, with a support shaft provided at the bottom of the column.

[0009] Furthermore, two electric push rods are symmetrically arranged, and the electric push rods pass through the clearance hole and are rotatably connected to the unloading plate and the support shaft, respectively.

[0010] Furthermore: the feeding roller is located below the storage box near the discharge port, the apex of the feeding roller is higher than the upper surface of the conveyor belt, and a tensioning structure is provided at the bottom of each conveyor belt.

[0011] Furthermore, the positioning component includes a positioning slide sleeve on which locking pins are mounted.

[0012] Furthermore, two through slots are symmetrically arranged on both sides of the storage box, the through slots are vertically arranged and penetrate through the top of the storage box.

[0013] Furthermore, the unloading plate is made of 204 stainless steel, and the rotating connection of the unloading plate is located outside the storage box.

[0014] Furthermore, the width of the height-limiting baffle is greater than the width of the storage bin.

[0015] Compared with existing technologies, the beneficial effects are:

[0016] 1. The design of the feeding roller and the conveyor belt is adopted (the tip of the feeding roller is higher than the surface of the conveyor belt) to ensure that the paperboard raw material falls accurately onto the conveyor belt after being separated into individual sheets, thus avoiding the paperboard raw material from being skewed or damaged.

[0017] 2. The servo motor precisely controls the speed of the feeding roller and dynamically adjusts the spacing of the cardboard to achieve synchronous matching with the gluing machine. Through innovative integration of mechanical structure, it effectively solves industry pain points such as material jamming, uneven spacing, and poor thickness adaptability in the feeding process of the gluing machine. It has the advantages of reliability, adaptability and ease of operation, and is especially suitable for large-scale production scenarios of multiple batches of cardboard boxes of different specifications.

[0018] 3. The electric push rod driven unloading plate design automatically raises the end as the raw material decreases (tilt angle adjustable), and compensates for frictional changes through gravity to maintain constant discharge port pressure; the dynamic adjustment of the storage tank tilt angle and the speed control of the feeding roller form a closed loop to solve the problem of uneven feeding caused by changes in the stacking height of raw materials in traditional equipment; the symmetrical layout of the double unloading plates and the external rotating shaft design reduce maintenance difficulty and enhance structural stability.

[0019] 4. The height limit cover with scale enables visual adjustment, and the discharge port height can be quickly locked by the limit slide to ensure that paperboard of different thicknesses is released one sheet at a time; the combination of positioning slide and locking pin provides rigid fixation to avoid the cover displacement caused by vibration.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-7 A paper packaging box gluing machine includes a gluing main body 4, a feeding device for supporting the stable conveying of paperboard raw materials is provided on one side of the gluing main body 4, and a storage device for storing the paperboard raw materials for stable release is provided at the end of the feeding device away from the gluing main body, and an adjustment device for sliding adjustment to release paperboard raw materials one by one according to thickness is provided at the discharge end of the storage device.

[0030] In this embodiment: the feeding device includes a frame body 101, on which several conveyor belts 102 are evenly distributed. Each conveyor belt 102 is driven by a rotary motor 103 at one end. Feed rollers 104 are arranged between the conveyor belts 102, and each feed roller 104 is driven by a servo motor 105 at one end. An auxiliary support assembly for support and adjustment is provided at the bottom of the frame body 101. The auxiliary support assembly includes two symmetrically arranged clearance holes 106 on the frame body 101 and a column 107 on the bottom surface of the frame body 101. A support shaft 108 is provided at the bottom of the column 107. The feed rollers 104 are located below the storage bin 201 near the discharge port 2. At position 02, the apex of the feeding roller 104 is higher than the upper surface of the conveyor belt 102, and a tensioning structure is provided at the bottom of each conveyor belt 102. During operation, the servo motor 105 drives the feeding roller 104 to rotate, pushing the bottom cardboard material out of the outlet 202 and onto the conveyor belt 102. The rotary motor 103 stably drives the conveyor belt 102 to support the cardboard material and move it into the gluing main body 4 for forming. The distance between two cardboard materials is controlled by the rotation speed of the feeding roller 104 driven by the servo motor 105. The clearance hole 106 is used to pass through the electric push rod 205. The column 107 supports the bottom end of the electric push rod 205 through the support shaft 108.

[0031] In this embodiment: the storage device includes a storage box 201, with a discharge port 202 at one bottom end of the storage box 201. A discharge plate 204 for changing the inclination angle of the cardboard raw material is rotatably mounted at the bottom end of the storage box 201 away from the discharge port 202. An electric push rod 205 is installed at the bottom end of the discharge plate 204. Two positioning components for tightening and limiting are symmetrically arranged on both sides of the storage box 201. Two discharge plates 204 and two electric push rods 205 are symmetrically arranged. The electric push rods 205 pass through clearance holes 106 and are rotatably connected to the discharge plate 204 and the support shaft 108, respectively. The positioning components include positioning sleeves 206, with locking pins 207 installed on the positioning sleeves 206. Two through slots 203 are symmetrically arranged on both sides of the storage box 201. The through slots 203 are vertical... The unloading plate 204 is made of 204 stainless steel and the rotating connection of the unloading plate 204 is located outside the storage box 201. During operation, the cardboard raw materials are stacked into the storage box 201. The through slots 203 on both sides of the storage box 201 facilitate the avoidance and handling. Under the action of gravity, the cardboard raw materials are pressed against the feeding roller 104 and the unloading plate 204. As the amount of cardboard raw materials in the storage box 201 decreases, the electric push rod 205 extends under the support of the support shaft 108, passes through the avoidance hole 106 to push the unloading plate 204, and drives the end of the cardboard raw materials to rise, so that the cardboard raw materials are tilted towards the discharge port 202. By adjusting the tilt angle of the cardboard raw materials, different degrees of friction can be obtained, which increases the stability of the cardboard raw material feeding operation.

[0032] In this embodiment: the adjustment device includes a height limiting cover 301, two limiting slide columns 302 are symmetrically arranged on both sides of the height limiting cover 301, an anti-detachment plate 303 is provided at the top of the limiting slide column 302, and a scale 304 is provided on the surface of the limiting slide column 302; the width of the height limiting cover 301 is greater than the width of the storage box 201; before operation, according to the thickness of the cardboard raw material, the limiting slide column 302 is slid up and down in the positioning sleeve 206 through the scale 304 to adjust the height of the height limiting cover 301 blocking the discharge port 202, so that the cardboard raw material is released one by one, and then the locking nail 207 is tightened to press the limiting slide column 302 to fix it.

[0033] Working principle: Before working, according to the thickness of the cardboard material, slide the limiting slide column 302 up and down in the positioning slide sleeve 206 through the scale 304 to adjust the height of the limiting cover 301 blocking the discharge port 202, so that the cardboard material is released one by one. Then tighten the locking nail 207 to press the limiting slide column 302 to fix it.

[0034] During operation, cardboard raw materials are stacked into the storage bin 201. The through slots 203 on both sides of the storage bin 201 facilitate clearance during handling. Under the action of gravity, the cardboard raw materials are pressed against the feeding roller 104 and the unloading plate 204. The servo motor 105 drives the feeding roller 104 to rotate, pushing the bottom layer of cardboard raw materials out of the discharge port 202 and onto the conveyor belt 102. The rotary motor 103 stably drives the conveyor belt 102 to support the movement of the cardboard raw materials, which then enter the gluing main body 4 for forming. The distance between two cardboard raw materials is controlled by the rotation speed of the feeding roller 104 driven by the servo motor 105. At the same time, as the amount of cardboard raw materials in the storage bin 201 decreases, the electric push rod 205 extends under the support of the support shaft 108, passes through the clearance hole 106, pushes the unloading plate 204, and lifts the end of the cardboard raw materials, causing the cardboard raw materials to tilt towards the discharge port 202. By adjusting the tilt angle of the cardboard raw materials, different degrees of friction are obtained, which increases the stability of the cardboard raw material feeding operation.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
