Description

Technical Field

[0001] This utility model belongs to the technical field of door leaf processing equipment, and in particular relates to a door leaf flipping mechanism. Background Technology

[0002] Door transfer printing increases recognizability and security, as well as enhances aesthetics and durability by printing special patterns and text on the door surface.

[0003] Currently, door panel transfer printing is usually done on one side only. After one side of the door panel is transferred in the transfer area, it needs to be flipped over and then transferred back to the transfer area to transfer the other side. Due to the large size and weight of the door panel frame, manual flipping is not only labor-intensive but also time-consuming and inefficient.

[0004] Therefore, there is an urgent need for a door leaf flipping mechanism that can reduce labor intensity and improve flipping efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a door leaf flipping mechanism to solve the problems existing in the background art.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A door leaf flipping mechanism includes a frame and a flipping mechanism located within the frame. The flipping mechanism includes a drive motor, a clamping assembly, a rotating frame, and U-shaped tracks located on both sides of the rotating frame. The rotating frame has an octagonal frame structure, and two sets of symmetrical roller frames are provided in the middle of the rotating frame. The clamping assembly is located between the two sets of roller frames, and the door leaf is located between the two sets of roller frames. The door leaf is fixed by the clamping assembly.

[0008] The U-shaped track is fixed on both sides of the frame, and the rotating frame is provided with a ring of rollers corresponding to the position of the U-shaped track. The rollers cooperate with the U-shaped track, and the rotating frame is rotatably connected to the frame through the rollers and the U-shaped track.

[0009] The drive motor is fixed to the bottom of the frame. The drive motor is equipped with a steel rope drive wheel and a first steel wire rope. The first steel wire rope wraps around the rotating frame once and is connected to the steel rope drive wheel. The rotating frame is driven to rotate by the drive motor and the first steel wire rope.

[0010] Furthermore, the clamping assembly includes a telescopic cylinder, a guide rail, a fixed plate, a movable plate, a steel rope bogie, and a second steel wire rope. Two sets of the steel rope bogies are fixed on both sides of two sets of roller frames. The steel rope bogies are equipped with guide wheels. The second steel wire rope passes around the two sets of second roller frames and connects to the guide wheels. The two ends of the guide rail are fixed to the two side walls of the roller frame. The four corners of the movable plate pass through the guide rail and are slidably connected to the guide rail. The middle part of the movable plate is fixed to the second steel wire rope. The cylinder seat of the telescopic cylinder is fixed to one side of the roller frame. One end of the piston rod of the telescopic cylinder is equipped with a push plate. One side of the push plate passes through the guide rail and is slidably connected to the guide rail. The other side of the push plate is fixedly connected to the second steel wire rope. The fixed plate is fixed on the roller frame near the cylinder seat of the telescopic cylinder.

[0011] Furthermore, the steel rope drive wheel and the first steel wire rope are located in the middle of the rotating frame, and the rotating frame is provided with a steel rope pressure plate corresponding to the position of the first steel wire rope.

Detailed Implementation

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] See Figures 1-4 This utility model provides a technical solution:

[0023] like Figures 1-4 As shown, a door leaf flipping mechanism includes a frame 1 and a flipping mechanism 2 located within the frame 1. The flipping mechanism 2 includes a drive motor 3, a clamping assembly 4, a rotating frame 5, and U-shaped tracks 6 located on both sides of the rotating frame 5. The rotating frame 5 has an octagonal frame structure, and two sets of symmetrical roller frames 7 are provided in the middle of the rotating frame 5. The clamping assembly 4 is located between the two sets of roller frames 7, and the door leaf is located between the two sets of roller frames 7. The door leaf is fixed by the clamping assembly 4.

[0024] The U-shaped track 6 is fixed on both sides of the frame 1. The rotating frame 5 is provided with a ring of rollers 51 corresponding to the position of the U-shaped track 6. The rollers 51 cooperate with the U-shaped track 6. The rotating frame 5 is rotatably connected to the frame 1 through the rollers 51 and the U-shaped track 6.

[0025] The drive motor 3 is fixed to the bottom of the frame 1. The drive motor 3 is equipped with a steel rope drive wheel 31 and a first steel wire rope 32. The first steel wire rope 32 wraps around the rotating frame 5 once and is connected to the steel rope drive wheel 31. The rotating frame 5 is driven to rotate by the drive motor 3 and the first steel wire rope 32.

[0026] Through the above technical solution, the U-shaped track 6 is fixed on both sides of the frame 1. Since the rotating frame 5 has an octagonal frame structure, the rotating frame 5 is supported on the U-shaped track 6 by a ring of rollers 51 on the outer ring and can rotate around the U-shaped track 6. The middle of the rotating frame 5 is provided with two rows of symmetrically arranged roller frames 7. When the roller frames 7 are rotated to the horizontal by the rotating frame 5, the height of the roller frames 7 is the same as the height of the external conveyor belt, and the door can directly enter between the two rows of roller frames 7.

[0027] The door leaf entering the roller frame 7 is fixed by the clamping assembly 4, so that the door leaf can rotate and flip together with the rotating frame 5. After flipping, the door leaf can be output from the roller frame 7 along the length of the door leaf.

[0028] The specific flipping process is as follows: Since the drive motor 3 is located at the bottom of the frame 1, the steel cable drive wheel 31 is connected to the output shaft of the drive belt. The first steel wire rope 32 is wound around the steel cable drive wheel 31 and then around the entire rotating frame 5. At the same time, the first steel wire rope 32 is fixed to the frame of the rotating frame 5 through the steel cable pressure plate 33 to prevent the first steel wire rope 32 from deviating or slipping. The drive motor 3 drives the first steel wire rope 32 to rotate around the steel cable drive wheel 31, so that the rotating frame 5 connected to the first steel wire rope 32 can rotate on the U-shaped track 6 to complete the flipping of the door leaf. The length of the first steel wire rope 32 in this scheme allows the rotating frame 5 to complete a 180° rotation by the forward rotation of the drive motor 3, and then be reset by the reverse rotation of the drive motor 3. The entire flipping mechanism 2 has a simple structure, which facilitates the input of the door leaf along the length direction, the flipping, and the output along the length direction.

[0029] The specific clamping process of the door leaf is as follows: The clamping assembly 4 includes a telescopic cylinder 44, a guide rail 42, a fixed plate 41, a movable plate 43, a steel rope guide frame 45, and a second steel wire rope 47. The two sets of steel rope guide frames 45 are fixed on both sides of the two sets of roller frames 7. The steel rope guide frame 45 is provided with a guide wheel 46. The second steel wire rope 47 passes around the two sets of second roller frames 7 and is connected to the guide wheel 46. The two ends of the guide rail 42 are fixed to the two side walls of the roller frame 7. The four corners of the movable plate 43 are... The movable plate 43 passes through the guide rail 42 and is slidably connected to the guide rail 42. The middle part of the movable plate 43 is fixed to the second steel wire rope 47. The cylinder seat of the telescopic cylinder 44 is fixed to one side of the roller frame 7. One end of the piston rod of the telescopic cylinder 44 is provided with a push plate 48. One side of the push plate 48 passes through the guide rail 42 and is slidably connected to the guide rail 42. The other side of the push plate 48 is fixedly connected to the second steel wire rope 47. The fixing plate 41 is fixed on the roller frame 7 near the cylinder seat of the telescopic cylinder 44.

[0030] With the above technical solution, when the piston rod of the telescopic cylinder 44 extends, the push plate 48 is slid out along the sliding guide rail 42 by the piston rod. At the same time, the push plate 48 drives the second steel wire rope 47 to rotate away from the cylinder seat position of the telescopic cylinder 44. At this time, the second steel wire rope 47 passes around the guide wheel 46 of the steel wire rope bogie 45 and drives the movable plate 43 to slide along the guide rail 42. The upper layer of the second steel wire rope 47 is connected to the push plate 48, and the lower layer of the second steel wire rope 47 is connected to the movable plate 43. At this time, the movable plate 43 moves towards the fixed plate 41 to complete the clamping of the middle door leaf.

[0031] The direction of the piston rod extending from the telescopic cylinder 44 is changed to the clamping direction of the movable plate 43 towards the fixed plate 41 by the second wire rope 47 and the wire rope guide frame 45. When the piston rod retracts into the telescopic cylinder 44, the distance between the movable plate 43 and the fixed plate 41 is at its greatest under the reversing action of the wire rope guide frame 45, which facilitates the insertion of the door leaf.

[0032] Furthermore, the roller 51 is an I-shaped roller, and the U-shaped track 6 is located in the I-shaped groove of the roller 51 to prevent the roller 51 from dislodging from the U-shaped track 6 when rotating.

[0033] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
