Description

Technical Field

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

[0002] Paper boxes are the most widely used packaging products. Depending on the materials used, there are corrugated paper boxes, single-layer paper boxes, etc., and they come in various specifications and models. Three-layer and five-layer paper boxes are commonly used, 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 corrugated cardboard, while the core paper is made of corrugated paper. The colors and textures of different types of paper vary. Currently, cardboard box folding machines often fail to create effective creases, hindering the subsequent folding and collection by workers. Therefore, we propose a new cardboard box folding machine. Utility Model Content

[0003] The purpose of this invention is to provide a paper box folding machine to solve the problems mentioned in the background art.

[0004] In view of this, the present invention provides a paper box folding machine, comprising: A U-shaped frame, wherein fixed plates are symmetrically fixedly installed inside the U-shaped frame, and rotating columns are symmetrically rotatably installed between the two fixed plates. Rollers are fixedly installed on the rotating columns, and a transmission belt is installed between the two rollers for transmission. A fixed frame is fixedly installed inside a U-shaped frame and above the conveyor belt. A roller is fixedly installed inside the fixed frame. An L-shaped plate is symmetrically fixedly installed at the bottom of the fixed frame. A baffle plate is fixedly installed on one side of the L-shaped plate. Two low-bend plates are fixedly installed on the top of two fixed plates and located behind the two L-shaped plates respectively. Folding blocks are fixedly installed at the tail ends of the two low-bend plates respectively. A support frame is fixedly installed inside the U-shaped frame and located behind the two folding blocks. Several rotating wheels are rotatably installed inside the support frame. A power assembly is disposed on one side of one of the fixed plates and is used to drive the two rotating columns to rotate.

[0005] In this technical solution, a power assembly drives two rotating columns to rotate, which in turn drive rollers to rotate, ensuring that the two rollers can drive the conveyor belt for transmission. At this time, the personnel can place the folded cardboard box flat between the top of the two fixed plates and the bottom of the two L-shaped plates, with the folded cardboard box still in contact with the rotating roller and the conveyor belt. Subsequently, the conveyor belt drives the folded cardboard box to move. Under the action of friction, the folded cardboard box also drives the rotating roller to rotate. At the same time, the two sides of the folded cardboard box will be pressed against the low folding plate, and the cardboard box will move with the conveyor belt to the bottom of the two baffle plates. Under the blocking action of the two baffle plates, the curved surface on the low folding plate will slowly press the folded cardboard box to slowly bend it until the cardboard box moves with the conveyor belt to the contact of the two folding blocks. The inclined surface of the two folding blocks will continue to press the two sides of the cardboard box to fold it until the two sides of the cardboard box are pressed into the bottom of the folding blocks. Subsequently, the folded cardboard box moves with the conveyor belt and is removed from the U-shaped frame after being pressed by several rotating rollers.

[0006] In the above technical solution, the power component further includes: The motor is fixedly mounted on one side of one of the fixed plates, and the output shaft of the motor is coaxially connected to one of the rotating columns; A support plate is fixedly installed inside the U-shaped frame and located between two rollers.

[0007] In this technical solution, the motor is connected to the power supply and started. The output shaft of the motor can drive one of the rotating columns to rotate. The rotation of one of the rotating columns will drive the first rotating wheel to rotate. Subsequently, the first rotating wheel will drive the second rotating wheel to rotate via the conveyor belt. The rotating second rotating wheel will drive the second rotating column to rotate, ensuring that the conveyor belt can continuously convey.

[0008] In the above technical solution, the top of the support plate contacts the inner side of the conveyor belt, the width of the support plate is equal to the width of the conveyor belt, and the top side of the conveyor belt is flush with the top side of the fixing plate.

[0009] In this technical solution, the support plate is designed to prevent the conveyor belt from bending, ensuring that the conveyor belt always rests against the cardboard box and carries the cardboard box continuously.

[0010] In the above technical solution, the bottom of the L-shaped plate is flush with the bottom of the baffle plate, and the distance between the L-shaped plate and the fixed plate is 0.8-1cm.

[0011] In this technical solution, it is ensured that the cardboard box can be placed between the L-shaped plate and the fixed plate, and when the two sides of the cardboard box are bent, it can be folded into the space between the folding block and the folding stop plate.

[0012] In the above technical solution, a rubber sleeve is further fixedly installed on the roller, the distance between the rubber sleeve and the conveyor belt is 0.2-0.8cm, and the thickness of the rubber sleeve is 5cm.

[0013] In this technical solution, the rubber sleeve is pressed against the cardboard box when it is placed on the conveyor belt. When the conveyor belt moves the cardboard box, the cardboard box will rotate under the action of friction, preventing the cardboard box from falling off the conveyor belt. When the cardboard box is thick, the rubber sleeve will also deform under the pressure of the cardboard box, ensuring that the cardboard box is not damaged.

[0014] In the above technical solution, the baffle plate is further located between the two low baffle plates, and the tail end of the baffle plate is located below the two rotating wheels.

[0015] In this technical solution, when the conveyor belt moves the cardboard box, the two sides of the folded cardboard box will be pressed against the low folding plate. As the cardboard box moves with the conveyor belt to the bottom of the two baffle plates, the curved surface on the low folding plate will slowly press the folded cardboard box to bend slowly under the obstruction of the two baffle plates. This ensures that the cardboard box is squeezed and shaped by the two rotating wheels on the conveyor belt and the two baffle plates.

[0016] In the above technical solution, a rubber ring is further fixedly installed on the rotating wheel 2, the distance between the rubber ring and the baffle plate is 0.2-0.8cm, and the thickness of the rubber ring is 5cm.

[0017] In this technical solution, the rubber ring is pressed against the cardboard box. Under the action of friction, the cardboard box can drive the rubber ring to rotate. When the cardboard box is thick, the rubber sleeve will also deform under the pressure of the cardboard box, ensuring that the cardboard box is not damaged.

[0018] In the above technical solution, furthermore, a number of support legs are fixedly installed at the bottom of the U-shaped frame.

[0019] In this technical solution, the structural stability of the U-shaped frame is ensured.

[0020] The beneficial effects of this utility model are: This cardboard box folding machine, through its power assembly, fixed plates, rotating columns, rollers, conveyor belt, support plate, fixed frame, rotating wheel one, L-shaped plate, folding stop plate, low folding plate, folding block, and rotating wheel two, is equipped with a power assembly that drives two rotating columns to rotate, which in turn drive the rollers to rotate, ensuring that the two rollers can drive the conveyor belt for transport. At this time, the operator can place the folded cardboard box flat between the top of the two fixed plates and the bottom of the two L-shaped plates, with the folded cardboard box still in contact with rotating wheel one and the conveyor belt. Subsequently, the conveyor belt moves the folded cardboard box, and under the action of friction, the folded cardboard box also drives rotating wheel one to rotate. Simultaneously, the undone cardboard box is pressed against the low folding plate on both sides. As the box moves along the conveyor belt to the bottom of the two baffle plates, the curved surface on the low folding plate slowly presses the undone cardboard box, causing it to bend gradually. This continues until the box moves along the conveyor belt to the point where the two folding blocks contact each other. The inclined surfaces of the two folding blocks then continue to press the sides of the box, folding it until the sides are pressed into the bottom of the folding blocks. Subsequently, the folded box moves along the conveyor belt and is removed from the U-shaped frame by the pressure of several rotating wheels. This ensures that the box can quickly and effectively produce creases and facilitates subsequent folding and collection by workers. Attached Figure Description

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0024] Example 1: This example provides a paper box folding machine, including: U-shaped frame 1, with fixed plates 2 symmetrically fixedly installed inside the U-shaped frame 1, rotating columns 3 symmetrically rotatably installed between the two fixed plates 2, rollers 31 fixedly installed on the rotating columns 3, and a transmission belt 4 drivingly installed between the two rollers 31; A fixed frame 5 is fixedly installed inside the U-shaped frame 1 and above the conveyor belt 4. A roller 31 is fixedly installed inside the fixed frame 5. An L-shaped plate 6 is symmetrically fixedly installed at the bottom of the fixed frame 5. A baffle plate 61 is fixedly installed on one side of the L-shaped plate 6. Two low-bend plates 7 are fixedly installed on the top of two fixed plates 2 and located behind two L-shaped plates 6 respectively. Folding blocks 8 are fixedly installed at the tail ends of the two low-bend plates 7 respectively. A support frame 9 is fixedly installed inside the U-shaped frame 1 and located behind the two folding blocks 8. Several rotating wheels 91 are rotatably installed inside the support frame 9. A power assembly is disposed on one side of one of the fixed plates 2 and is used to drive the two rotating columns 3 to rotate.

[0025] The system utilizes a power assembly that drives two rotating columns 3 to rotate, which in turn rotate rollers 31. This ensures that the two rollers 31 can drive the conveyor belt 4 for transport. At this point, an folded cardboard box can be placed flat between the top of the two fixed plates 2 and the bottom of the two L-shaped plates 6, with the folded box still in contact with the rotating wheel 51 and the conveyor belt 4. Subsequently, the conveyor belt 4 moves the folded cardboard box, and under the action of friction, the folded cardboard box also drives the rotating wheel 51 to rotate. Simultaneously, the folded cardboard... The two sides of the box will be pressed against the low folding plate 7, and the box will move to the bottom of the two baffle plates 61 along with the conveyor belt 4. Under the obstruction of the two baffle plates 61, the curved surface on the low folding plate 7 will slowly press the undone box to bend slowly until the box moves with the conveyor belt 4 to the contact of the two folding blocks 8. The inclined surfaces of the two folding blocks 8 will continue to press the two sides of the box to fold until the two sides of the box are pressed into the bottom of the folding blocks 8. Then, the folded box moves with the conveyor belt 4 and is removed from the U-shaped frame 1 by the pressure of several rotating wheels 91.

[0026] Example 2: This example provides a paper box folding machine, which, in addition to the technical solutions of the above examples, also has the following technical features, wherein the power component includes: Motor 32, which is fixedly installed on one side of one of the fixing plates 2, and the output shaft of motor 32 is coaxially connected to one of the rotating columns 3; The support plate 42 is fixedly installed inside the U-shaped frame 1 and located between the two rollers 31.

[0027] When the motor 32 is powered on and started, the output shaft of the motor 32 can drive one of the rotating columns 3 to rotate. The rotation of one of the rotating columns 3 will drive the rotating wheel 51 to rotate. Subsequently, the rotating wheel 51 will drive the other rotating wheel 51 to rotate via the conveyor belt 4. The rotating wheel 51 will drive the other rotating column 3 to rotate, ensuring that the conveyor belt 4 can continuously convey.

[0028] Example 3: This example provides a paper box folding machine, which, in addition to the technical solutions of the above examples, also has the following technical features: the top of the support plate 42 is in contact with the inner side of the conveyor belt 4, the width of the support plate 42 is equal to the width of the conveyor belt 4, and the top side of the conveyor belt 4 is flush with the top side of the fixing plate 2.

[0029] Specifically, the support plate 42 is designed to prevent the conveyor belt 4 from bending, ensuring that the conveyor belt 4 always rests against the cardboard box and moves with the cardboard box.

[0030] Example 4: This example provides a paper box folding machine. In addition to the technical solutions of the above examples, it also has the following technical features: the bottom of the L-shaped plate 6 and the folding stop plate 61 are flush, and the distance between the L-shaped plate 6 and the fixed plate 2 is 0.8-1cm, and the distance between the folding block 8 and the folding stop plate 61 is 0.2-0.8cm.

[0031] Specifically, it ensures that the cardboard box can be placed between the L-shaped plate 6 and the fixed plate 2, and that when the two sides of the cardboard box are bent, it can be folded into the space between the folding block 8 and the folding stop plate 61.

[0032] Example 5: This example provides a paper box folding machine, which, in addition to the technical solutions of the above examples, also has the following technical features: a rubber sleeve is fixedly installed on the roller 31, the distance between the rubber sleeve and the conveyor belt 4 is 0.2-0.8cm, and the thickness of the rubber sleeve is 5cm.

[0033] Specifically, when the cardboard box is placed on the conveyor belt 4, the rubber sleeve can press against the cardboard box. When the conveyor belt 4 moves the cardboard box, the cardboard box will cause the rubber sleeve to rotate under the action of friction, preventing the cardboard box from falling off the conveyor belt 4. When the cardboard box is thick, the rubber sleeve will also deform under the pressure of the cardboard box, ensuring that the cardboard box is not damaged.

[0034] Example 6: This example provides a paper box folding machine, which, in addition to the technical solutions of the above examples, also has the following technical features: the folding baffle 61 is located between two low folding plates 7, and the tail end of the folding baffle 61 is located below two of the rotating wheels 91.

[0035] When the conveyor belt 4 moves the cardboard box, the two sides of the folded cardboard box will be pressed against the low fold plate 7. As the cardboard box moves with the conveyor belt 4 to the bottom of the two baffle plates 61, the curved surface on the low fold plate 7 will slowly press the folded cardboard box to bend slowly under the obstruction of the two baffle plates 61. This ensures that the cardboard box will be squeezed and shaped by the two rotating wheels 91 on the conveyor belt 4 and the two baffle plates 61.

[0036] Example 7: This example provides a paper box folding machine. In addition to the technical solutions of the above examples, it also has the following technical features: a rubber ring is fixedly installed on the rotating wheel 91, the distance between the rubber ring and the folding plate 61 is 0.2-0.8cm, and the thickness of the rubber ring is 5cm.

[0037] In this process, the rubber ring is pressed against the cardboard box. Under the action of friction, the cardboard box can drive the rubber ring to rotate. When the cardboard box is thick, the rubber sleeve will also deform under the pressure of the cardboard box, ensuring that the cardboard box is not damaged.

[0038] Example 8: This example provides a paper box folding machine, which, in addition to the technical solutions of the above examples, also has the following technical features: the bottom of the U-shaped frame 1 is fixedly equipped with several support legs.

[0039] Among these measures, ensuring the structural stability of the U-shaped frame 1 is crucial.

[0040] Working principle: When the motor 32 is powered on and started, the output shaft of the motor 32 can drive one of the rotating columns 3 to rotate. The rotation of one of the rotating columns 3 will drive the rotating wheel 51 to rotate. Subsequently, the rotating wheel 51 will drive the other rotating wheel 51 to rotate via the conveyor belt 4. The rotating wheel 51 will drive the other rotating column 3 to rotate, ensuring that the conveyor belt 4 can continuously convey. Subsequently, the folded cardboard box can be placed flat between the top of the two fixed plates 2 and the bottom of the two L-shaped plates 6, with the folded cardboard box still in contact with the rotating wheel 51 and the conveyor belt 4. Then, the conveyor belt 4 drives the folded cardboard box to move. Under the action of friction, the folded cardboard box also drives the rotating wheel 51 to rotate. At the same time, the two sides of the folded cardboard box will be pressed against the low fold plate 7, and the cardboard box will move with the conveyor belt 4 to the bottom of the two baffle plates 61. Under the blocking action of the two baffle plates 61, the curved surface on the low fold plate 7 will slowly press the folded cardboard box to slowly bend it until the cardboard box moves with the conveyor belt 4 to the contact of the two fold blocks 8. The inclined surface of the two fold blocks 8 will continue to press the two sides of the cardboard box to fold it until the two sides of the cardboard box are pressed into the bottom of the fold blocks 8. Then, the folded cardboard box moves with the conveyor belt 4 and is removed from the U-shaped frame 1 after being pressed by several rotating wheels 91. The above process ensures that the cardboard box can quickly and effectively generate creases and facilitates subsequent folding and collection by workers.

[0041] The cardboard boxes to be processed are conveyed to the starting end of the conveyor belt 4 by an automatic feeding mechanism. Under the action of the power component (motor 32 drives rotating column 3, roller 31 drives conveyor belt 4), they are conveyed forward. During the process, the cardboard boxes enter the processing area through the gap between L-shaped plate 6 and fixed plate 2. The sides are initially shaped by the pressure of low folding plate 7. With the blocking cooperation of folding plate 61, the boxes are slowly bent by the curved surface of low folding plate 7 to form initial creases. Then, the creases are further squeezed by the inclined surface of folding block 8 to complete the crease shaping. Then, the cardboard boxes with creases are conveyed to the support frame 9. Under the continuous pressure of several rotating rollers 91, they enter the pressure holding stage to ensure that the creases are stable and do not spring back. Finally, the boxes are automatically discharged from the end of the conveyor belt 4, realizing a continuous operation process from automatic feeding to crease forming, pressure holding and shaping and then automatic discharge.

[0042] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
