Description

Technical Field

[0001] This utility model relates to a cooling flipping machine, and more particularly to a continuous side-flipping cooling flipping machine. Background Technology

[0002] Engineered wood products (PWP) are boards or molded products made from wood or other non-wood plant materials. These materials are mechanically processed into various unit materials and then bonded together with or without adhesives and other additives. After final hot pressing, PWP reaches a high temperature and needs to be cooled to a specified temperature before stacking and output. Otherwise, heat accumulation during stacking can cause the boards to warp and deform, potentially even leading to fires. Currently, PWP cooling is often achieved using a star-shaped side-flipping machine. This machine uses radially arranged support rods to gradually flip the PWP from one side to the other, exposing it to the external environment for cooling. To support streamlined operations, conveyor mechanisms are typically attached to both sides of the star-shaped flipping machine for continuous cooling and flipping. However, current technology typically involves a single flipping process before stacking, often resulting in insufficient cooling of PWP, especially thicker boards. While there are existing methods to accelerate cooling with air blowers, these only produce a noticeable surface cooling effect. Since engineered wood products are made from wood, their thermal conductivity is relatively poor. Hasty air cooling cannot adequately cool the interior of the engineered wood, especially for thicker boards. Therefore, a technology is needed to provide a method that enables uniform and thorough cooling of engineered wood to address these issues. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a continuous side-flipping cooling flipping machine that can realize continuous cooling flipping operation, and achieve uniform and thorough cooling.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a continuous side-flipping cooling flipping machine, including at least two flipping devices arranged in sequence, with the flipping directions of adjacent flipping devices being opposite, an inlet conveying device provided on the flipping side of the flipping device, and an outlet conveying device provided on the flipping-down side of the flipping device, wherein the downstream inlet conveying device receives the plate output by the upstream outlet conveying device.

[0005] As a preferred technical solution, the end of the infeed conveying device is provided with an infeed limiting device.

[0006] As a preferred technical solution, the infeed limiting device includes a limiting baffle movably installed on the infeed conveying device. The limiting baffle can extend upward beyond the conveying surface of the infeed conveying device, and the limiting baffle is connected to a limiting controller.

[0007] As a preferred technical solution, the plate conveying device is provided with a plate-pushing device that can push the plate away from the flipping device.

[0008] As a preferred technical solution, the dropping plate pushing device includes a pushing cylinder installed on the side of the plate conveying device near the flipping device, and the piston rod end of the pushing cylinder is provided with a pushing plate.

[0009] As a preferred technical solution, the pusher plate is positioned higher than the conveying surface of the plate conveying device, and the pusher plate is positioned to push the plate component obliquely upward.

[0010] As a preferred technical solution, the flipping device includes a flipping frame, on which a flipping main shaft is rotatably mounted. Several circumferentially arranged flipping support rods are fixedly mounted on the flipping main shaft, forming a support space between adjacent flipping support rod groups. An anti-falling blocking structure is fixedly provided on the flipping main shaft at each support space to prevent boards from falling onto the flipping main shaft. The ends of the flipping support rod groups extend to the corresponding infeed conveyor and outfeed conveyor. The infeed conveyor and outfeed conveyor are respectively provided with support clearance openings corresponding to the flipping support rod groups. A flipping driver is provided between the flipping main shaft and the flipping frame.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, exemplary embodiments of the present invention are described only by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0025] like Figures 1 to 10As shown, the continuous side-flipping cooling flipping machine includes at least two flipping devices 1 arranged in sequence. The flipping directions of two adjacent flipping devices 1 are opposite. The flipping side of the flipping device 1 is provided with an infeed conveying device 2, and the flipping side of the flipping device 1 is provided with an outfeed conveying device 3. The downstream infeed conveying device 2 is configured to receive the plates output by the upstream outfeed conveying device 3.

[0026] The flipping device 1 flips the plate from the inlet conveyor 2 on the flipping side and gradually flips it onto the outlet conveyor 3 on the flipping side. During this flipping process, the plate is exposed to the external environment for heat dissipation and cooling. In this embodiment, the outlet conveyor 3 on the flipping side and the inlet conveyor 2 on the flipping side of the downstream flipping device 1 form a connection between the plate conveying of multiple flips. The plate can be flipped back and forth for cooling, which not only meets the continuous cooling flipping requirements of the production line, but also doubles the cooling time, resulting in uniform and thorough cooling of the plate.

[0027] The flipping device 1 described in this embodiment includes a flipping frame 11, on which a flipping main shaft 12 is rotatably mounted. A plurality of flipping support rod groups 13 arranged circumferentially are fixedly provided on the flipping main shaft 12, and a support space 14 is formed between two adjacent flipping support rod groups 13. A fall-prevention blocking structure 15 is fixedly provided on the flipping main shaft 12 at each of the support spaces 14 to prevent the board from falling onto the flipping main shaft 12. The ends of the flipping support rod groups 13 extend to the corresponding infeed conveying device 2 and outfeed conveying device 3. The infeed conveying device 2 and outfeed conveying device 3 are respectively provided with support clearance openings 24 corresponding to the flipping support rod groups 13. A flipping driver 16 is provided between the flipping main shaft 12 and the flipping frame 11.

[0028] After the board reaches the infeed conveyor 2, the flipper driver 16 drives the flipper spindle 12 to rotate by an angle. The flipper support rod assembly 13, located below the conveying surface of the infeed conveyor 2, rises and lifts the board on the infeed conveyor 2. When the next board arrives at the infeed conveyor 2, the above action is repeated, and the boards are sequentially lifted into the respective support spaces 14. At the outfeed conveyor 3, after the flipper driver 16 drives the flipper spindle 12 to rotate by an angle, the flipper support rod assembly 13 rotates from above the conveying surface of the outfeed conveyor 3 to below it, and the board supported on it naturally falls onto the outfeed conveyor 3 and is output.

[0029] Of course, the conveying surfaces of both the infeed conveyor 2 and the outfeed conveyor 3 should be near the axial height of the flip plate main shaft 12. This allows the relatively long flip plate support rod assembly 13 to smoothly flip or drop the plates in a horizontal or slightly tilted state. The anti-fall blocking structure 15 ensures that the plates are always in the relatively wide support plate space 14. This naturally creates a larger gap between plates in adjacent support plate spaces 14, resulting in better heat dissipation and cooling. At the same time, the relatively wide support plate space 14 also facilitates smooth output from the outfeed conveyor 3.

[0030] The flap support rod assembly 13 includes at least two flap support rods. Preferably, the flap support rods at corresponding positions in each flap support rod assembly 13 are arranged in the same circumferential direction on the flap main shaft 12. Therefore, regardless of the angle to which the flap main shaft 12 rotates, the position of the flap support rods when they reach the infeed conveyor 2 or the outfeed conveyor 3 is fixed, and the pallet clearance opening 24 is also fixed. Based on the above structure, the anti-fall blocking structure 15 in this embodiment is an anti-fall blocking ring fixedly installed on the flap support rods in the same circumferential direction. The anti-fall blocking ring prevents the plate from falling towards the flap main shaft 12 while improving the bending resistance of the flap support rod assembly 13, ensuring pallet reliability. Preferably, a plurality of circumferentially arranged reinforcing rods 17 are fixedly provided between adjacent anti-fall blocking rings to further enhance the pallet supporting capacity of the flap support rod assembly 13.

[0031] The board feeding conveying device 2 includes a board feeding conveying frame 21, on which a plurality of board feeding conveying rollers 22 are mounted in an arrangement. The board feeding conveying rollers 22 are all connected to a board feeding conveying driver 23. The space between several groups of adjacent board feeding conveying rollers 22 forms the pallet clearance opening 24. The board discharging conveying device 3 has a similar structural principle to the board feeding conveying device 2, which is readily apparent to those skilled in the art and will not be described in detail here.

[0032] Preferably, the end of the board feeding conveying device 2 is provided with a board feeding limiting device 4 to limit the input position of the input board. In this embodiment, the board feeding limiting device 4 includes a limiting baffle 41 movably mounted on the board feeding conveying device 2. The limiting baffle 41 extends upward beyond the conveying surface of the board feeding conveying device 2, and is connected to a limit controller 42. By extending upward beyond the conveying surface of the board feeding conveying device 2 to block the input board, the limiting control purpose is achieved.

[0033] In this embodiment, the limiting baffle 41 is vertically slidably mounted on the infeed conveying device 2, or more specifically, on the infeed conveying frame 21. The limiting controller 42 includes a limiting control cylinder, which drives the limiting baffle 41 to rise vertically to block the board. Alternatively, the limiting baffle 41 can be oscillatingly mounted on the infeed conveying device 2, with the limiting control cylinder driving it to swing and block the board; this is a variation of the same technical means, and this embodiment should also be within the protection scope of this utility model.

[0034] Preferably, the plate conveying device 3 is provided with a plate-pushing device 5 that can push the plate away from the flipping device 1. This pushing action prevents the plate from contacting or colliding with the flipping device 1 during output, facilitating smooth output. In this embodiment, the plate-pushing device 5 includes a pushing cylinder 51 installed on the side of the plate conveying device 3 near the flipping device 1. The piston rod end of the pushing cylinder 51 is provided with a pushing plate 52. The pushing cylinder 51 drives the pushing plate 52 to directly push, achieving the above-mentioned pushing effect.

[0035] Preferably, the pusher plate 52 is positioned higher than the conveying surface of the plate conveying device 3, and the pusher plate 52 pushes the plate upward at an angle. That is, the pusher plate 52 performs the push-away action before the plate falls onto the plate conveying device 3. At this time, because the angle of the flip-plate support rod assembly 13 supporting the plate is very small, the plate is not prone to slippage during the support process, so the push-away action is effective and reliable. At the same time, because the contact area between the flip-plate support rod assembly 13 and the plate is small, the contact friction is relatively small, the push-away action requires less force, and the plate is less likely to suffer friction damage.

[0036] This embodiment achieves cooling by continuously flipping the plates back and forth, satisfying the continuous cooling requirements of the production line while doubling the cooling time, resulting in uniform and thorough cooling of the plates. Furthermore, through optimized designs for plate entry limiting and plate exit pushing, this embodiment allows multiple flipping devices 1 to form a continuous, orderly side-flipping cooling operation, improving operational continuity. Although this embodiment only illustrates two flipping devices 1, in actual use, three, four, or even more can be set as needed. When multiple flipping devices 1 are set up, they can be used for thicker engineered wood panels. Of course, in this case, when the production line is used to produce thinner engineered wood panels, some of the flipping devices 1 can be shut down to reduce energy consumption. At this time, the board conveying device 3 on the flipping side of the last flipping device 1 can form a straight output by using the board infeeding conveying device 2 and / or board outfeeding conveying device 3 on the side corresponding to the shut-down flipping device 1. Of course, the board infeeding limit device 4 at the board infeeding conveying device 2 corresponding to the shut-down flipping device 1 is also removed, thereby expanding the scope of use.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
