Description

Technical Field

[0001] This utility model relates to the field of honeycomb core processing equipment, specifically a core board feeding mechanism. Background Technology

[0002] The core board is made of multiple layers of base paper. The core board is cut into core strips by a cross-cutting mechanism. The core strips are pressed together and laminated to form a continuous honeycomb core. The core board feeding mechanism delivers the core board to the cross-cutting station for cutting at a fixed length. Because the core board is wide, the feeding roller required for core board feeding is long. The longer the feeding roller is, the more prone it is to deformation. High-speed feeding will cause jumping, unstable feeding and inaccurate feeding length.

[0003] To address this issue, the utility model patent CN217123334U, entitled "A Core Board Feeding Device," discloses that the feeding roller is composed of unit rollers. The unit rollers are shorter, making them less prone to twisting during transmission. This allows for a smaller diameter, reducing processing costs and errors. They also prevent jumping during high-speed feeding, ensuring stable feeding. This design is suitable for high-speed honeycomb paperboard production lines. Furthermore, the unit rollers are lighter and have less inertia, resulting in stable fixed-length feeding with minimal error and uniform thickness of the honeycomb core after molding.

[0004] The main problems with the above-mentioned patents are: 1. High processing cost; 2. Cumbersome and inefficient installation of unit rollers; 3. The pressure rollers must avoid the glue lines on the core plate during feeding, and the lateral position of the pressure rollers is fixed, which increases the difficulty of debugging. Utility Model Content

[0005] In view of the technical problems existing in the background art, the technical problem solved by this utility model is to provide a core board feeding mechanism that is not only stable and accurate in feeding, but also convenient in installation and debugging, and has low processing cost.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the core board feeding mechanism is characterized in that it includes a feeding component, which includes a feeding wheel, a pressure wheel and a crossbeam; The feeding wheel is provided in a plurality of manners, and the plurality of feeding wheels are mounted on the main shaft. The main shaft is rotatably mounted on the frame and is connected to the motor. The pressure roller is rotatably mounted on the adjusting seat. The pressure roller is positioned above the feeding roller and the two press against each other to feed the material. The circumferential surface of the pressure roller is provided with a rubber strip clearance groove. The crossbeam is provided with a guide member, which is arranged laterally. The adjusting seat is arranged on the guide member, and the lateral position of the adjusting seat on the guide member can be adjusted.

[0007] This utility model uses a combination of a feeding wheel and a main shaft to form a feeding roller, which not only reduces the difficulty and cost of processing and installation, but also makes the whole unit lightweight, with low inertia, stable and accurate feeding. At the same time, it can adjust the lateral position of the pressure roller according to the position of the rubber strip on the core board surface, so that the rubber strip clearance groove of the pressure roller corresponds to the rubber strip on the core board, avoiding the rubber line, making the adjustment convenient and efficient.

[0008] Preferably, the crossbeam is rotatably mounted on the frame via a pivot, the pivot being connected to a connecting rod, the connecting rod being connected to a driving component that drives its swing, and the driving component being mounted on the frame.

The pressure strip and the lower support plate work together to prevent the core board from jumping and improve the stability of feeding.

[0010] As a preferred embodiment, when the core plate is inserted, the crossbeam rotates, and the adjusting seat swings upward accordingly, increasing the distance between the pressure roller and the feeding roller, as well as the distance between the pressure strip and the lower support plate. During feeding, the adjusting seat swings downward, the distance between the pressure roller and the feeding roller decreases, and the two press together to feed the material. The distance between the pressure strip and the lower support plate decreases and matches the height of the core plate.

[0011] Preferably, the pressure roller has several rubber strip clearance grooves, which correspond to the rubber strips on the core plate.

[0012] Preferably, the adjusting seat is connected to a mounting plate, which is positioned above the crossbeam and locked to the crossbeam by a locking bolt.

[0021] The following describes the embodiments and related details and working principle of this utility model with reference to the accompanying drawings. The core board 15 feeding mechanism includes a feeding component, which includes feeding wheels 3, pressure rollers 7, and a crossbeam 9. Several feeding wheels 3 are provided, and these wheels are mounted on a main shaft 4. The main shaft is rotatably mounted on a frame and connected to a motor 13. The feeding wheels are lightweight, not easily deformed, and easy to process. The feeding wheels 3 on the main shaft 4 are spaced apart, resulting in a lightweight and low-inertia overall, leading to more stable and precise feeding. To facilitate installation and adjustment of the lateral position of the feeding wheels, the feeding wheels 3 are sleeved outside the main shaft 4, and their lateral position on the main shaft is adjustable. Both ends of the feeding wheels are connected to the main shaft 4 via expansion sleeves 14. Without the expansion sleeves locking, the feeding wheels move laterally on the main shaft. After the lateral position of the feeding wheels 3 is determined, they are locked to the main shaft via the expansion sleeves. The pressure roller 7 is rotatably mounted on the adjusting seat 6. The pressure roller is positioned above the feeding roller 3, and the two press together to feed material. The number of pressure rollers can be less than or equal to the number of feeding rollers, resulting in a large and stable clamping force. The circumferential surface of the pressure roller is provided with adhesive strip clearance grooves 17. Several adhesive strip clearance grooves are provided on the pressure roller, and each groove corresponds to an adhesive strip on the core plate 15. The pressure roller presses on the un-adhesive portion of the core plate, avoiding the adhesive strip on the core plate. The core plate moves forward under the clamping force of the pressure roller 7 and the feeding roller 3. The crossbeam 9 is rotatably mounted on the frame. The crossbeam is provided with a guide member 8, which is arranged laterally. The adjusting seat 6 is positioned on the guide member 8, and its lateral position on the guide member is adjustable. The guide member in the figure is a linear guide rail, but guide rods, guide grooves, or other guide members can also be used. Since the width of the core plate 15 varies and the glue application position differs, to ensure that the glue strip clearance groove 17 on the pressure roller corresponds to the glue strip on the core plate 15, the lateral position of the pressure roller is adjusted by moving the adjusting seat laterally along the guide member. The lateral movement of the adjusting seat can be adjusted using a screw mechanism. The screw is rotatably mounted on the frame, and the adjusting seat is threadedly connected to the screw. Rotating the screw moves the adjusting seat laterally. The adjusting seat can also be manually adjusted. The adjusting seat is connected to a mounting plate 16, which is positioned above the crossbeam 9. The mounting plate 16 and the crossbeam 9 are locked together by a locking bolt. Using a locking bolt provides a simple structure, excellent locking effect, and convenient operation as the locking position is above the crossbeam.

[0022] This utility model uses a combination of a feeding roller 3 and a main shaft 4 to form a feeding roller, which not only reduces the difficulty and cost of processing and installation, but also makes the whole unit lightweight, with low inertia, and provides stable and accurate feeding. At the same time, it can adjust the lateral position of the pressure roller 7 according to the position of the rubber strip on the surface of the core plate 15, so that the rubber strip clearance groove 17 of the pressure roller 7 corresponds to the rubber strip on the core plate 15 and avoids the rubber line.

[0023] Along the core board conveying path, an anti-vibration component is provided in front of the feeding roller. The anti-vibration component includes a pressure strip 2 and a lower support plate 1. The pressure strip 2 is installed on an adjusting seat 6, and a plurality of pressure strips are provided on the adjusting seat, with a rubber strip spacing 18 between the pressure strips, and the pressure strips avoid the rubber strips. The lower support plate 1 is located below the pressure strip 2, and the distance between the lower support plate and the pressure strip matches the height of the core board 15. When the core board is threaded, the crossbeam 9 rotates, and the adjusting seat 6 swings upward accordingly. The distance between the pressure roller 7 and the feeding roller 3, and the distance between the pressure strip 2 and the lower support plate 1, both increase, facilitating the threading of the core board 15. When feeding, the adjusting seat 6 swings downward, and the distance between the pressure roller 7 and the feeding roller 3 decreases, and the two press together to feed the core board. The distance between the pressure strip and the lower support plate decreases and matches the height of the core board 15. The pressure roller 7 and the feeding roller 3 press together to feed the core board, and the pressure strip 2 and the lower support plate 1 cooperate to prevent the core board from jumping, further improving the stability of the feeding.

[0024] The crossbeam 9 is rotatably mounted on the frame via a pivot 12. The pivot 12 is connected to a connecting rod 11, which is connected to a driving component 10 that drives its swing. The driving component is mounted on the frame and can be a cylinder. (See...) Figure 2 and 3 The cylinder pulls the connecting rod 11, causing it to swing upward. The connecting rod drives the crossbeam 9 to rotate, causing the pressure bar 2 and pressure roller 7 to lift upward. Conversely, the cylinder pushes the connecting rod to swing downward, causing the connecting rod to drive the crossbeam 9 to rotate in the opposite direction, causing the pressure bar 2 and pressure roller 7 to press down.

[0025] To further improve the feeding accuracy, a feeding tray 5 is provided behind the pressure roller 7 along the core plate conveying path. The feeding tray 5 supports the core plate 15 and conveys it forward smoothly.

[0026] The main shaft 4 is divided into a left shaft and a right shaft. One end of the left shaft and the right shaft are connected by a coupling, and the other end of each is connected to a motor 13. The dual-motor drive provides high torque and power output, enabling high-frequency and precise feeding.
