Description

Technical Field

[0001] This utility model relates to the field of sheet production technology, specifically an MCM sheet turning machine. Background Technology

[0002] MCM sheet is a new type of energy-saving and low-carbon decorative material. As a wall decoration material, it is lightweight, flexible, has a variety of appearances and shapes, and is weather-resistant. As a floor decoration material, it is wear-resistant, slip-resistant, and comfortable underfoot. It is easy and quick to install, shortens the construction period compared to traditional materials, saves space and costs, and is not easy to fall off.

[0003] The production process of MCM sheets mainly includes the following steps: raw material preparation, mixing, molding, baking and curing, and surface treatment. Generally, MCM sheets do not necessarily need to be flipped. However, flipping may be necessary in certain construction stages or processing techniques, for example, to improve material performance: 1. Stress relief: Flipping helps release internal stress in the material, reducing deformation and cracking caused by prolonged unidirectional stress or stress concentration, thus extending service life. 2. Uniform heating: In some special processes involving heat treatment, flipping allows the MCM sheet to be heated evenly on both sides, further improving the material's stability and performance. Utility Model Content

[0004] The purpose of this invention is to provide an MCM sheet flipping machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An MCM sheet flipping machine includes a frame and a pneumatic gripper. The pneumatic gripper is mounted on the frame via a flipping mechanism. The pneumatic gripper is used to clamp the sheet. When the flipping mechanism is running, the pneumatic gripper can flip the sheet and then return it to its initial reset position.

[0007] The frame has a drive roller and a driven roller mounted horizontally at both ends. The outer walls of the drive roller and the driven roller are equipped with conveyor belts. When the drive roller rotates, the sheet can be moved to the pneumatic gripper via the conveyor belt.

[0008] The frame is equipped with a drive mechanism, the flipping mechanism is connected to the drive mechanism through a transmission structure, and the drive roller is connected to the drive mechanism through a speed-increasing component. When the drive mechanism is running, it can drive the transmission structure and the speed-increasing component to run alternately.

[0009] As a further embodiment of this utility model:

[0010] The flipping mechanism includes a fixed frame fixedly mounted on the frame and a rotating shaft horizontally rotatably mounted on the fixed frame, and the pneumatic gripper is fixedly mounted on one end of the rotating shaft;

[0011] A slide rail is fixedly installed on the fixed frame along the length of the frame, and a toothed plate is slidably installed on the slide rail. A first gear is fixedly installed at the other end of the rotating shaft, and the first gear meshes with the toothed plate.

[0012] As a further improvement of this utility model:

[0013] The flipping mechanism also includes a bracket and a turntable. The bracket is fixedly mounted on the fixed frame, and the turntable is rotatably mounted on the bracket via a rotating column.

[0014] An eccentric column is fixedly installed on one side of the turntable, and the eccentric column and the toothed plate are rotatably connected by a connecting rod.

[0015] As a further improvement of this utility model:

[0016] The driving mechanism includes a driving disk, a first driven disk, and a second driven disk. The driving disk cooperates with the first driven disk and the second driven disk respectively. When the driving disk rotates, the first driven disk and the second driven disk will rotate alternately.

[0017] The active disk, the first driven disk, and the second driven disk are rotatably mounted on the frame via the first rotating rod, the second rotating rod, and the third rotating rod, respectively. A motor is fixedly mounted on the frame, and the output end of the motor is coaxially and fixedly connected to one end of the first rotating rod.

[0018] As a further improvement of this utility model:

[0019] The transmission structure includes a first transmission wheel and a second transmission wheel, with the first transmission wheel coaxially fixed on the second rotating rod.

[0020] The second transmission wheel is coaxially fixed on the rotating column, and the first transmission wheel and the second transmission wheel are connected by a first belt.

[0021] As a further improvement of this utility model:

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] When the drive mechanism is running, the transmission structure and speed-increasing component will operate alternately. During the operation of the transmission structure, it can cooperate with the flipping mechanism to flip the sheet over and then return it to its initial reset position, waiting for the next clamping and flipping. During this process, the speed-increasing component remains stationary. When the speed-increasing component is running, it can drive the drive roller to rotate. The drive roller will cooperate with the driven roller and the conveyor belt to move the sheet to the pneumatic gripper, waiting for the pneumatic gripper to clamp it. During this process, the transmission structure remains stationary. When the sheet moves to the pneumatic gripper, the pneumatic gripper will clamp and fix it, rotate it 180 degrees and then release it, and then return to the initial position after rotating 180 degrees.

[0028] This application, through the cooperation of pneumatic grippers, active rollers, driven rollers, conveyor belts, drive mechanisms, transmission structures, speed-increasing components, and flipping mechanisms, can regularly and continuously flip and transport multiple sheets. This not only helps to release the internal stress of the sheet material and extend its service life, but also makes the heat treatment of the sheet material more uniform. Compared with traditional equipment, the flipping efficiency is higher, and the cooperation between the various components is stable and orderly. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Furthermore, the elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0039] Please see Figures 1-7 In this embodiment of the utility model, an MCM sheet flipping machine includes a frame 1 and a pneumatic gripper 2. The pneumatic gripper 2 is mounted on the frame 1 via a flipping mechanism. The pneumatic gripper 2 is used to clamp the sheet. When the flipping mechanism is running, the pneumatic gripper 2 can flip the sheet and then return it to its initial reset.

[0040] The frame 1 is horizontally rotatably equipped with a drive roller 3 and a driven roller 4 at both ends. The outer walls of the drive roller 3 and the driven roller 4 are equipped with conveyor belts 5. When the drive roller 3 rotates, the sheet can be moved to the pneumatic gripper 2 by the conveyor belt 5.

[0041] The frame 1 is equipped with a drive mechanism. The flipping mechanism is connected to the drive mechanism through a transmission structure. The drive roller 3 is connected to the drive mechanism through a speed-increasing component. When the drive mechanism is running, it can drive the transmission structure and the speed-increasing component to run alternately.

[0042] In this scheme, when the drive mechanism is running, the transmission structure and the speed-increasing component will operate alternately. During the operation of the transmission structure, it can cooperate with the flipping mechanism to flip the sheet over and then return to its initial reset, waiting for the next clamping and flipping. During this process, the speed-increasing component remains stationary. When the speed-increasing component is running, it can drive the drive roller 3 to rotate. The drive roller 3 will cooperate with the driven roller 4 and the conveyor belt 5 to move the sheet to the pneumatic gripper 2, waiting for the pneumatic gripper 2 to clamp it. During this process, the transmission structure remains stationary. When the sheet moves to the pneumatic gripper 2, the pneumatic gripper 2 will clamp and fix it, rotate 180 degrees and then release it, and then return to the initial position after rotating 180 degrees.

[0043] As a further embodiment of this utility model, the flipping mechanism includes a fixed frame 6 fixedly mounted on the frame 1 and a rotating shaft 7 horizontally rotatably mounted on the fixed frame 6, and the pneumatic gripper 2 is fixedly mounted on one end of the rotating shaft 7;

[0044] A slide rail 8 is fixedly installed on the fixed frame 6 along the length direction of the frame 1. A toothed plate 9 is slidably installed on the slide rail 8. A first gear 10 is fixedly installed at the other end of the rotating shaft 7. The first gear 10 meshes with the toothed plate 9.

[0045] In this embodiment, since the rotating shaft 7 is horizontally rotatably mounted on the fixed frame 6, and the first gear 10 fixed on the rotating shaft 7 meshes with the toothed plate 9 slidably mounted on the slide rail 8, when the toothed plate 9 slides horizontally back and forth, the first gear 10 will drive the rotating shaft 7 to rotate forward and reverse.

[0046] Among them, the toothed plate 9 and the first gear 10 are configured such that when the toothed plate 9 moves back and forth once, the first gear 10 first rotates 180 degrees clockwise and then 180 degrees counterclockwise.

[0047] Since the pneumatic gripper 2 is fixedly installed at one end of the rotating shaft 7 and the first gear 10 is fixedly installed at the other end of the rotating shaft 7, the pneumatic gripper 2 will follow the first gear 10 through the rotating shaft 7 to rotate 180 degrees forward and then 180 degrees backward.

[0048] As a further embodiment of this utility model, the flipping mechanism also includes a bracket 11 and a turntable 13. The bracket 11 is fixedly mounted on the fixed frame 6, and the turntable 13 is rotatably mounted on the bracket 11 via a rotating column 12.

[0049] An eccentric column 14 is fixedly installed on one side of the turntable 13, and the eccentric column 14 and the toothed plate 9 are rotatably connected by a connecting rod 15.

[0050] In this embodiment, since the eccentric column 14 fixedly installed on one side of the turntable 13 and the toothed plate 9 are rotatably connected by the connecting rod 15, when the turntable 13 rotates one revolution, the toothed plate 9 will move horizontally back and forth once on the slide rail 8.

[0051] Since the turntable 13 is mounted on the bracket 11 via the rotating column 12, the turntable 13 will rotate one full turn as the rotating column 12 rotates one full turn.

[0052] As a further embodiment of this utility model, the driving mechanism includes a driving disk 16, a first driven disk 17, and a second driven disk 18. The driving disk 16 cooperates with the first driven disk 17 and the second driven disk 18 respectively. When the driving disk 16 rotates, the first driven disk 17 and the second driven disk 18 will rotate alternately.

[0053] The active disk 16, the first driven disk 17 and the second driven disk 18 are rotatably mounted on the frame 1 via the first rotating rod 19, the second rotating rod 20 and the third rotating rod 21 respectively. A motor 22 is fixedly mounted on the frame 1, and the output end of the motor 22 is coaxially and fixedly connected to one end of the first rotating rod 19.

[0054] In this embodiment, the drive disc 16, the first driven disc 17, and the second driven disc 18 together form the Maltese cross movement structure. Therefore, when the drive disc 16 rotates, the first driven disc 17 and the second driven disc 18 will rotate alternately.

[0055] Since the driving disk 16, the first driven disk 17, and the second driven disk 18 are rotatably mounted on the frame 1 via the first rotating rod 19, the second rotating rod 20, and the third rotating rod 21, respectively, and the output end of the motor 22 is coaxially and fixedly connected to one end of the first rotating rod 19, when the motor 22 is started, the output end of the motor 22 will drive the driving disk 16 to rotate via the first rotating rod 19. When the first driven disk 17 rotates, the second rotating rod 20 will rotate accordingly; when the second driven disk 18 rotates, the third rotating rod 21 will rotate accordingly.

[0056] As a further embodiment of this utility model, the transmission structure includes a first transmission wheel 23 and a second transmission wheel 24, wherein the first transmission wheel 23 is coaxially fixed on the second rotating rod 20;

[0057] The second transmission wheel 24 is coaxially fixed on the rotating column 12, and the first transmission wheel 23 and the second transmission wheel 24 are connected by the first belt 25.

[0058] In this embodiment, since the first transmission wheel 23 fixed on the second rotating rod 20 and the second transmission wheel 24 fixed on the rotating column 12 are connected by the first belt 25, the rotating column 12 will rotate when the second rotating rod 20 rotates.

[0059] The diameter of the second transmission wheel 24 is four times that of the first transmission wheel 23. Therefore, when the second transmission wheel 24 rotates 90 degrees, the first transmission wheel 23 rotates one revolution.

[0060] As a further embodiment of this utility model, the speed-increasing component includes a fourth rotating rod 26 rotatably mounted on the frame 1 and a second gear 27 coaxially fixed on the fourth rotating rod 26.

[0061] A third gear 28 is coaxially fixed on the third rotating rod 21, and the second gear 27 and the third gear 28 mesh with each other;

[0062] A third transmission wheel 29 is coaxially fixed on the fourth rotating rod 26, and a fourth transmission wheel 30 is coaxially fixed on one end of the active roller shaft 3. The third transmission wheel 29 and the fourth transmission wheel 30 are connected by a second belt 31.

[0063] In this embodiment, since the gear 27 fixed on the fourth rotating rod 26 and the gear 28 fixed on the third rotating rod 21 mesh with each other, the fourth rotating rod 26 will rotate when the third rotating rod 21 rotates.

[0064] Furthermore, since the No. 3 transmission wheel 29 fixed on the No. 4 rotating rod 26 and the No. 4 transmission wheel 30 fixed at one end of the drive roller shaft 3 are connected by the second belt 31, when the No. 4 rotating rod 26 rotates, the drive roller shaft 3 will rotate accordingly.

[0065] Among them, the diameters of gear 27, gear 28, drive wheel 29 and drive wheel 30 are adapted to the spacing of the sheets placed on the conveyor belt 5 to ensure that the conveyor belt 5 accurately conveys multiple sheets to the pneumatic gripper 2 in sequence.
