Description

Technical Field

[0001] This utility model relates to the field of nail and glue integrated machine. Background Technology

[0002] Cardboard boxes are typically made of corrugated cardboard or honeycomb cardboard folded together and require nailing for reinforcement. These thick cardboard types are strong and have a certain cushioning effect, making them suitable for packaging heavy objects.

[0003] The increased thickness of the cardboard enhances its rigidity and bending resistance, but also makes folding and shaping the carton more difficult. Folding this type of thick cardboard results in low folding precision, leading to weak stability and easy deformation of the carton. Utility Model Content

[0004] In view of the technical problems existing in the background art, the technical problem to be solved by this utility model is to provide a nailing and gluing machine with high folding accuracy and good folding effect.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This type of nailing and gluing integrated machine is characterized by: including a carton folding mechanism, wherein the carton folding mechanism includes a lower conveying component and a folding component.

[0006] The lower conveying component includes a left conveyor belt and a right conveyor belt;

[0007] The folding component includes a left folding component and a right folding component, both of which include a torsion belt, a drive wheel, several guide wheels, and several folding discs. The torsion belt is mounted on the drive wheel, and the part of the torsion belt that contacts the carton is the folding section. The folding section is gradually twisted to face downwards and presses against the left or right conveyor belt. The guide wheels are located inside the folding section of the torsion belt and are in contact with the inner surface of the folding section. The folding discs are rotatably mounted on a mounting plate and arranged longitudinally. The mounting plate is located above the left and right conveyor belts. The folding discs are inclined, with the lowest point of the folding disc facing outwards and forming the folding part.

[0008] The folding part of the folding disc corresponds to the side fold line of the cardboard. The two sides of the cardboard are gradually folded along the side fold line under the push of the torsion belt. During this process, the cardboard and the folding disc roll into contact, and the resistance between the two is small. The cardboard will not shift during the conveying and folding process. At the same time, the folding disc plays a certain limiting role, which makes the cardboard folding effect better and more precise.

[0009] Preferably, the folding section is divided into a first folding section and a second pressing and folding section, the section where the twisted belt presses against the left or right conveyor belt is the second pressing and folding section, and the pressing and folding disc is disposed in the first folding section.

[0010] Preferably, the stapler-gluer also includes a stapler mechanism, which includes a stapler head, a conveying component, and a cardboard tray.

[0011] The pallet is disposed between the left conveyor belt and the right conveyor belt. The pallet includes a longitudinally arranged upper baffle and a lower pallet. The lower pallet is disposed at the same height as the left and right conveyor belts. The upper baffle has an inclined section and a horizontal section. The horizontal section is disposed in front of the inclined section. The inclined section enters the first folding section and gradually approaches the lower pallet along the conveying direction.

[0012] The conveying component is connected to the lower conveying component;

[0013] The nailing machine head is connected to the horizontal section of the upper baffle.

[0014] The cardboard is wide, and the lower support plate supports it to prevent it from sagging. The two sides of the cardboard are folded over and placed on the upper baffle, separating them from the center surface of the cardboard. As the cardboard moves forward, the two sides overlap and enter the upper baffle horizontally. Then, the nailing machine head staples the two sides to fix them in place.

[0015] Preferably, the pressing and folding plate is frustum-shaped.

[0016] Preferably, the folding discs are provided in at least two sets. The outer diameter of the folding discs in the front folding disc set is smaller than that in the rear folding disc set, and the angle between the folding discs in the front folding disc set and the horizontal plane is smaller than that between the folding discs in the rear folding disc set and the horizontal plane. Under the push of the torsion belt, the two sides of the cardboard gradually fold towards the center of the cardboard, and the space and angle between them gradually decrease. The folding discs change from large to small accordingly, further improving the accuracy of the folding.

[0017] Preferably, the second folding section is provided with a lateral limiting member, which is a rolling bearing, arranged sequentially along the conveying direction. The two sides of the cardboard are in contact with the center surface of the cardboard and move forward under the conveying of the lower conveyor and the twisting belt. The two sides of the cardboard folded along the side crease line roll into contact with the rolling bearings. The left and right rolling bearings limit the cardboard during conveying to prevent it from moving.

[0018] Preferably, the torsion belt is equipped with a plurality of folding rods, the arrangement of which along the conveying direction matches the torsion angle of the torsion belt. The folding rods assist the torsion belt in folding the two sides of the cardboard.

[0019] Preferably, the folding rods are arranged in sequence along the conveying direction as a first support rod, a second folding rod, a third pressure rod, and a fourth stop rod. As the cardboard moves forward, both sides of the cardboard are supported by the first support rod, folded upwards and inwards by the second folding rod, pressed inwards and downwards by the third pressure rod, and kept folded downwards by the fourth stop rod.

[0025] The following description, in conjunction with the accompanying drawings, details the embodiments of this utility model and their working principles. (See attached figures) Figure 2 The X-axis is horizontal, also representing the left and right direction; the Y-axis is vertical, also representing the front and back direction, with the arrow on the Y-axis pointing forward; and the Z-axis is vertical, also representing the up and down direction.

[0026] This type of integrated gluing and stapling machine includes a carton folding mechanism and a carton stapling mechanism. The carton folding mechanism includes a lower conveyor component 8 and a folding component. The lower conveyor component 8 includes a left conveyor belt and a right conveyor belt 2. Figure 1 and Figure 2 The cardboard box folding mechanism only shows the right side; the left side is not shown. Pressure rollers 17 are located above the beginning of the left and right conveyor belts 2. These rollers 17 press against the left and right conveyor belts 2 to transport the cardboard, ensuring a more stable entry. The folding mechanism includes a left folding component and a right folding component. Figure 1 and Figure 2The first part only has a right-folding component. The left and right folding components are symmetrically arranged, each including a torsion belt 1, a drive wheel 10, several guide wheels 9, and several pressure discs 3. The torsion belt 1 is mounted on the drive wheel 10, which is driven to rotate by a motor. The part of the torsion belt 1 that contacts the carton is the folding section, which gradually twists downwards to a horizontal position and presses against the left or right conveyor belt 2. The folding section is divided into a first folding section 15 and a second pressure section 16. The section where the torsion belt 1 presses against the left or right conveyor belt 2 is the second pressure section 16, located in front of the first folding section 15. The pressure discs 3 are located on the first folding section 15. A lateral limiting member, a rolling bearing 4, is provided on the side of the second pressure section 16, arranged sequentially along the conveying direction. The guide wheel 9 is disposed inside the folded section of the torsion belt 1 and is in contact with the inner surface of the folded section. The pressure folding disc 3 is rotatably mounted on the mounting plate and arranged longitudinally. The mounting plate is disposed above the left conveyor belt and the right conveyor belt 2. The pressure folding disc 3 is inclined, with its lowest point facing outward and forming the pressure folding part 31. (See attached figure) Figure 2 and 4 The folding disc 3 of the right folding component tilts downwards and to the right, with its lowest point on the right side. Its folding part 31 is aligned with the right crease line of the cardboard. The folding disc 3 of the left folding component tilts downwards and to the left, with its folding part 31 aligned with the left crease line of the cardboard. The cardboard is conveyed forward by the lower conveyor 8, with both sides of the cardboard placed on the torsion belt 1. As the cardboard moves forward, the torsion belt 1 causes both sides of the cardboard to gradually fold along the side crease line. During this process, the folding part 31 of the folding disc 3 always blocks the crease line, and the cardboard and the folding disc 3 roll in contact. The resistance between them is small, and the cardboard does not shift during the conveying and folding process, resulting in high folding accuracy and excellent folding effect. When both sides of the cardboard are fully folded and fit against the center surface of the cardboard, it moves forward under the conveying of the lower conveyor 8 and the torsion belt 1. The two sides of the cardboard folded along the side crease line roll in contact with the rolling bearings 4. The left and right rolling bearings 4 limit the cardboard during conveying to prevent it from moving, allowing the cardboard to stably enter the nailing station for nailing.

[0027] To further improve folding accuracy, the folding disc 3 is frustoconical. The folding part 31 of the folding disc 3 blocks the crease line, and the side of the folding disc 3 blocks the side of the cardboard above the crease line. At least two sets of folding discs 3 are provided. The outer diameter of the folding disc 3 in the front set is smaller than that in the rear set, and the angle between the folding disc 3 in the front set and the horizontal plane is smaller than that in the rear set. Under the push of the torsion belt 1, the two sides of the cardboard gradually fold towards the center, and the space and angle between them gradually decrease, causing the folding disc 3 to change from large to small.

[0028] The torsion belt 1 is equipped with several folding rods, the arrangement of which along the conveying direction corresponds to the torsion angle of the torsion belt 1. The folding rods are arranged sequentially along the conveying direction as a first support rod 11, a second folding rod 12, a third pressure rod 13, and a fourth stop rod 14. These folding rods assist the torsion belt 1 in folding the two sides of the cardboard. As the cardboard moves forward, its two sides pass sequentially through the first support rod 11, the second folding rod 12, the third pressure rod 13, and the fourth stop rod 14. The first support rod 11 supports the two sides of the cardboard, the second folding rod 12 folds the two sides of the cardboard upwards and inwards, the third pressure rod 13 presses the two sides of the cardboard downwards and inwards, and the fourth stop rod 14 keeps the two sides of the cardboard folded downwards.

[0029] The nailing mechanism includes a nailing head, a conveying component 8, and a cardboard support. The conveying component 8 connects to the lower conveying component 8 and receives the folded cardboard. The conveying component 8 includes an upper conveyor belt 81 and a lower conveyor belt 82, which are positioned on both sides of the cardboard support. The folded cardboard is held and conveyed by the upper and lower conveyor belts 81 and 82. The cardboard support is positioned between the left and right conveyor belts 2 and includes a longitudinally arranged upper baffle 7 and a lower support plate 6. The lower support plate 6 is at the same height as the left and right conveyor belts 2. Given the wide width of the cardboard, the lower support plate 6 supports the cardboard and prevents it from sagging. The upper baffle 7 includes an inclined section and a horizontal section. The horizontal section is positioned in front of the inclined section. The inclined section enters the first folding section 15 and gradually approaches the lower support plate 6 along the conveying direction until it enters the horizontal section. The nailing head connects to the horizontal section of the upper baffle 7. The inclined section supports the two sides of the folded cardboard and isolates them from the center of the cardboard. As the cardboard moves forward, the two sides enter the horizontal section, and the two sides of the cardboard are completely folded and in a horizontal state. The nailing head then securely fastens the folded two sides.

[0030] The working principle of the preferred embodiment is further explained below with reference to the accompanying drawings: The cardboard is molded with crease lines by a molding machine. The cardboard is fed in by a paper feeding mechanism and moves forward under the conveyor belts 1 (left and right) and 1 (twisting belt). The two sides of the cardboard are placed on the twisting belt 1 and the first support rod 11. As the cardboard moves forward, the pressing part 31 of the pressing plate 3 is always pressed against the side crease lines of the cardboard. The twisting belt 1 pushes the two sides of the cardboard to fold along the side crease lines, and the folding rod guides the two sides of the cardboard to fold. The folded sides overlap on the upper baffle 7. As the cardboard continues to move forward, the two sides gradually approach the center surface of the cardboard until they are in contact. At this time, the two sides of the cardboard folded along the side crease lines roll into contact with the rolling bearings 4. The left and right rolling bearings 4 limit the cardboard in the conveying process to prevent it from moving and ensure that the cardboard enters the nailing station stably. The upper baffle 7 separates the two sides to be nailed from the center surface, and then the cardboard enters the nailing station. The nailing head 5 securely nails the two sides of the cardboard, and finally the cardboard is sent out to enter the next process.
