Description

Technical Field

[0001] This invention relates to the field of paperboard processing technology, and in particular to a paperboard processing apparatus. Background Technology

[0002] Cardboard is ubiquitous in my life. The main processing methods for cardboard are extrusion molding and die molding. Die molding involves adding pulp to a mold, molding it, and then demolding it. This processing method requires multiple steps, including filling the mold and then demolding it. It is not only complicated but also requires a lot of manpower. Summary of the Invention

[0003] In view of this, the present invention aims to provide a cardboard processing device to solve the technical problems of the traditional mold forming process being cumbersome and requiring a large amount of manpower.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a cardboard processing device, including a fixing part, a feeding component rotatably disposed inside the fixing part, a forming groove disposed between the fixing part and the feeding component, the feeding component injecting pulp into the forming groove, at least two forming grooves are provided, a mold opening component for opening the forming groove is slidably disposed on the fixing part, and a driving component for driving the mold opening component to slide is disposed on the feeding component.

[0005] Furthermore, the fixing part includes a fixing sleeve, which has an open groove and a sliding groove. The mold opening component slides in the sliding groove. The mold opening component seals one end of the open groove, and the feeding component seals the other end of the open groove. The open groove enclosed by the mold opening component and the feeding component is a forming groove.

[0006] Furthermore, the mold opening component includes an arc-shaped plate, one end of which is provided with a sliding end that slides inside a sliding groove. An arc-shaped spring is provided between the sliding end and the sliding groove. An extension plate is provided at the lower end of the arc-shaped plate so that the lower end of the opening groove is also open. The driving component drives the arc-shaped plate to slide by obstructing the component.

[0007] Furthermore, the obstruction assembly includes a fixed cylinder, a sliding movable bolt inside the fixed cylinder, a first spring between the movable bolt and the fixed cylinder, and a pushing part at the lower end of the movable bolt. The driving assembly drives the arc plate to slide through the pushing part.

[0008] Furthermore, the drive assembly includes a rotating ring, which is disposed on the feeding assembly. The rotating ring is provided with an obstruction groove, and the pushing part is an obstruction ball. After the obstruction ball enters the obstruction groove, the rotating ring drives the arc plate to slide. After the arc plate moves to the point where the open groove opens, the obstruction ball slides out from inside the obstruction groove.

[0009] Furthermore, the feeding assembly includes a rotating column, which is rotatably disposed inside the fixed sleeve. The rotating column has a feeding chamber inside and a feeding pipe communicating with the feeding chamber is provided on the rotating column. The feeding pipe is connected to the pulp pump feeding device, and a rotating ring is disposed on the feeding pipe.

[0010] Furthermore, the rotating column is equipped with a demolding component and a drying device. The demolding component is positioned above the obstruction groove. After the obstruction groove is driven to move until the open groove is opened, the demolding component pushes out the cardboard formed inside the open groove.

[0011] Furthermore, the demolding assembly includes a receiving groove disposed inside the rotating column, an ejector block slidably disposed inside the receiving groove, a second spring disposed between the receiving groove and the ejector block, a limiting groove disposed inside the rotating column, a limiting bolt slidably disposed inside the limiting groove, and the limiting bolt disposed on the ejector block.

[0012] Furthermore, the sliding sides of the ejector block are chamfered.

[0013] Beneficial effects: The feeding assembly rotates inside the fixed part. During the rotation of the feeding assembly, pulp is injected into the forming groove. Since there are at least two forming grooves, when the feeding assembly injects pulp into the next forming groove, the paper jam inside the previous forming groove is driven by the driving assembly to open the forming groove for opening the mold and discharging the paper.

[0015] As shown in the figure, a cardboard processing device includes a fixing part 1, a feeding component 2 rotatably disposed inside the fixing part 1, a forming groove 3 disposed between the fixing part 1 and the feeding component 2, the feeding component 2 injecting pulp into the forming groove 3, and at least two forming grooves 3 are provided. A mold opening component 4 for opening the forming groove 3 is slidably disposed on the fixing part 1, and a driving component 6 for driving the mold opening component 4 to slide is disposed on the feeding component 2.

[0016] The feeding assembly 2 rotates inside the fixed part 1. During the rotation of the feeding assembly 2, pulp is injected into the forming groove 3. Since there are at least two forming grooves 3, when the feeding assembly 2 injects pulp into the next forming groove 3, the paper jam inside the previous forming groove 3 is driven by the driving assembly 6 to open the forming groove 3 for opening the mold and discharging paper.

[0017] In this embodiment, the fixing part 1 includes a fixing sleeve 1-1, which has an open groove 1-2 and a sliding groove 1-3. The mold opening component 4 slides in the sliding groove 1-3. The mold opening component 4 seals one end of the open groove 1-2, and the feeding component 2 seals the other end of the open groove 1-2. The open groove 1-2 enclosed by the mold opening component 4 and the feeding component 2 is a forming groove 3. The mold opening component 4 includes an arc plate 4-1, which has a sliding end 4-2 at one end. The sliding end 4-2 slides inside the sliding groove 1-3. An arc spring 4-3 is provided between the sliding end 4-2 and the sliding groove 1-3. An extension plate 4-4 is provided at the lower end of the arc plate 4-1 so that the lower end of the open groove 1-2 is also open. The driving component 6 drives the arc plate 4-1 to slide through the obstruction component 5.

[0018] After the pulp is formed inside the forming groove 3, the arc plate 4-1 slides under the force of the obstruction component 5. The sliding end 4-2 slides into the sliding groove 1-3 and compresses the arc spring 4-3. Since the lower end of the arc plate 4-1 is provided with an extension plate 4-4, when the arc plate 4-1 slides, the lower end and the front end of the open groove 1-2 are opened to facilitate the demolding of the paper jam.

[0019] In this embodiment, the obstruction component 5 includes a fixed cylinder 5-1, a sliding movable bolt 5-2 inside the fixed cylinder 5-1, a first spring 5-3 between the movable bolt 5-2 and the fixed cylinder 5-1, and a pushing part 5-4 at the lower end of the movable bolt 5-2. The driving component 6 drives the arc plate 4-1 to slide through the pushing part 5-4. The driving component 6 includes a rotating ring 6-1, which is disposed on the feeding component 2. The rotating ring 6-1 is provided with an obstruction groove 6-2. The pushing part 5-4 is an obstruction ball. After the obstruction ball enters the obstruction groove 6-2, the rotating ring 6-1 drives the arc plate 4-1 to slide. After the arc plate 4-1 moves to the point where the open groove 1-2 is open, the obstruction ball slides out from inside the obstruction groove 6-2.

[0020] The rotating ring 6-1 rotates under the action of the feeding assembly 2. When the obstruction groove 6-2 moves to the position of the obstruction ball, the obstruction ball enters the obstruction groove 6-2. The rotating ring 6-1 drives the obstruction ball to move together through the obstruction groove 6-2. The obstruction ball drives the arc plate 4-1 to demold the cardboard through the fixed cylinder 5-1. When the arc plate 4-1 moves to the point where it can no longer move, the obstruction groove 6-2 will drive the obstruction ball to disengage from the obstruction groove 6-2. The compressed arc spring 4-3 drives the arc plate 4-1 to reset, so that the open groove 1-2 of the cardboard discharge forms the forming groove 3 again for the next pulp injection molding.

[0021] In this embodiment, the feeding assembly 2 includes a rotating column 2-1, which is rotatably disposed inside the fixed sleeve 1-1. The rotating column 2-1 is provided with a feeding chamber 2-2. The rotating column 2-1 is provided with a feeding pipe 2-3 that communicates with the feeding chamber 2-2. The feeding pipe 2-3 is connected to the pulp pump feeding device. A rotating ring 6-1 is disposed on the feeding pipe 2-3. The feeding pipe 2-3 is connected to a matching servo motor.

[0022] In this embodiment, the rotating column 2-1 is provided with a demolding component 7 and a drying device 8. The demolding component 7 is positioned above the obstruction groove 6-2. The obstruction groove 6-2 drives the demolding component 7 to eject the cardboard formed inside the open groove 1-2 after the open groove 1-2 is opened. The demolding component 7 includes a receiving groove 7-1, which is located inside the rotating column 2-1. An ejector block 7-2 is slidably provided inside the receiving groove 7-1. A second spring 7-3 is provided between the receiving groove 7-1 and the ejector block 7-2. The rotating column 2-1 is provided with a limiting groove 7-5, and a limiting bolt 7-4 is slidably provided inside the limiting groove 7-5. The limiting bolt 7-4 is located on the ejector block 7-2. The ejector block 7-2 has chamfers 7-6 on both sides of its sliding surface.

[0023] When the drive unit 6 drives the cardboard to demold, the second spring 7-3 pushes the ejector block 7-2 to slide from the inside of the receiving groove 7-1 and eject the cardboard from the inside of the open groove 1-2.
