Description

Technical Field

[0001] This utility model relates to the field of silicone product technology, specifically to a crossbar-type flipping mechanism for a silicone product extruder. Background Technology

[0002] Silica gel is a porous material with different particle sizes, formed by the appropriate dehydration of silica gel. It has an open porous structure and can adsorb many substances. Silica gel is chemically stable and does not react with any substance except strong alkalis and hydrofluoric acid. It is non-toxic and odorless, making it an environmentally friendly material. Silica gel has strong adsorption properties and is mainly used for physical adsorption. It can be regenerated and reused repeatedly. Therefore, it is often used as a desiccant, adsorbent, and catalyst carrier.

[0003] When using a silicone extruder to perform a flipping operation on a mold, given the mold's inherent length characteristics, the flipping process often requires reaching a certain height. However, most extruders currently have fixed height parameters, meaning they are only suitable for mold flipping needs within a specific size range. When faced with molds requiring different heights, the existing fixed height design becomes inadequate and cannot meet the flexible and varied practical application needs.

[0004] Therefore, a crossbar-type die-flipping mechanism for silicone product extruders is proposed. Utility Model Content

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. Example

[0025] Please see Figures 1-4This utility model provides a technical solution: a crossbar type flipping mechanism for a silicone product extruder, including a base 1, a connecting seat 2 fixedly installed on the top surface of the base 1, two connecting seats 2 arranged in front and behind, a fixing frame 3 fixedly installed on the top surface of the connecting seat 2, an adjustment mechanism 4 installed inside the fixing frame 3, and a flipping mechanism 5 installed above the base 1.

[0026] The adjustment mechanism 4 includes a drive unit and a support unit;

[0027] The flipping mechanism 5 includes a fixing part and a flipping part.

[0028] The drive unit includes a movable frame 41, which is located inside the fixed frame 3. A positioning rod 42 is fixedly installed on the inner wall of the fixed frame 3. The bottom surface of the positioning rod 42 is fixedly connected to the connecting seat 2. The lower end of the positioning rod 42 passes through the movable frame 41 and is slidably connected to the movable frame 41. A first cylinder 43 is fixedly installed on the front of the connecting seat 2. The upper end of the output shaft of the first cylinder 43 is fixedly connected to the movable frame 41.

[0029] Connecting frames 44 are fixedly installed on the lower ends of both sides of the movable frame 41. Gears 45 are installed in the bearings inside the connecting frames 44. A rack 46 is fixedly installed on the inner wall of the fixed frame 3. The gears 45 and rack 46 are meshed and connected.

[0030] The support includes a connecting rod 47, the lower end of which is hinged to the connecting seat 2. There are two connecting rods 47 on the left and right sides. The upper end of the connecting rod 47 is provided with a bearing block 48. The front of the movable frame 41 has a limit groove. A limit rod 49 is fixedly provided on the inner wall of the limit groove. The limit rod 49 passes through the bearing block 48 and is slidably connected to the bearing block 48.

[0031] Furthermore, in this embodiment, the first cylinder 43 is activated, which drives the moving frame 41 to rise and fall, providing a suitable flipping area for the mold. The positioning rod 42 positions the moving frame 41 to keep it stable during the rise and fall. When the moving frame 41 rises and falls, it drives the gear 45 to slide on the rack 46. When the first cylinder 43 drives the moving frame 41 to move to the appropriate position, the gear 45 meshes with the rack 46.

[0032] Furthermore, in this embodiment, the lifting and lowering of the moving frame 41 can be controlled by the first cylinder 43, thereby providing a suitable flipping area for the mold. The positioning rod 42 ensures the stability of the moving frame 41 during the lifting and lowering process, preventing the moving frame 41 from shifting or tilting during lifting and lowering. When the moving frame 41 is driven to the appropriate position by the first cylinder 43, the meshing of the gear 45 and the rack 46 achieves precise locking of the position. Example

[0033] Please see Figures 1-4Furthermore, based on Embodiment 1, the following is obtained: the fixed part includes a flipping frame 51, which is located between two front and rear movable frames 41. Clamping frames 52 are provided on both the left and right sides of the flipping frame 51. The clamping frames 52 pass through the flipping frame 51 and are slidably connected to the flipping frame 51. Connecting shafts 53 are fixedly provided on both the front and rear sides of the flipping frame 51. The connecting shafts 53 are connected to the bearings of the adjacent movable frames 41.

[0034] A second cylinder 54 is fixedly installed on the top surface of the tilting frame 51, and a lifting frame 55 is fixedly installed on the output shaft of the second cylinder 54. A limit frame 56 is installed in front of the lifting frame 55.

[0035] The limiting frame 56 is fixedly connected to the flipping frame 51. The front end of the lifting frame 55 is located inside the limiting frame 56 and is slidably connected to the inner wall of the limiting frame 56. Both ends of the lifting frame 55 are hinged with hinge rods 57, and the other end of the hinge rods 57 is hinged to the adjacent clamping frame 52.

[0036] The flipping part includes a placement block 58, which is fixedly connected to the adjacent movable frame 41. A third cylinder 59 is fixedly installed on the left side of the placement block 58. A drive rod 510 is hinged to the left end of the output shaft of the third cylinder 59. The front end of the drive rod 510 is hinged to the flipping frame 51. An arc frame 511 is installed behind the drive rod 510. The arc frame 511 is fixedly connected to the adjacent movable frame 41. The lower rear end of the drive rod 510 is located inside the arc frame 511 and is slidably connected to the inner wall of the arc frame 511.

[0037] Furthermore, in this embodiment, the mold is placed inside the flipping frame 51. The second cylinder 54 is activated, which drives the lifting frame 55 to rise and fall. When the lifting frame 55 rises and falls, it drives the two left and right hinge rods 57 to deflect. When the hinge rods 57 deflect, they drive the two left and right clamping frames 52 to move closer to each other. The clamping frames 52 fix the mold inside the flipping frame 51. The third cylinder 59 is activated, which drives the drive rod 510 to move. The arc frame 511 provides the running trajectory for the lower end of the drive rod 510. When the drive rod 510 moves, it causes the position of the left end connection of the flipping frame 51 to change, thereby causing the flipping frame 51 to flip.

[0038] Furthermore, in this embodiment, the left and right clamping frames 52, the hinge rod 57, and the lifting frame 55 are connected. When the lifting frame 55 is raised or lowered, the clamping frame 52 can stably approach and fix the flipping mold, ensuring the stability and safety of the flipping mold during the flipping process and avoiding the risk of the flipping mold falling off or being damaged. The flipping frame 51 achieves flipping through the cooperation of the drive rod 510 and the arc frame 511. The arc frame 511 provides a definite running trajectory for the drive rod 510, thereby ensuring that the flipping frame 51 can flip at a predetermined angle.

[0039] In use, the first cylinder 43 is activated, which drives the moving frame 41 to rise and fall, providing a suitable flipping area for the mold. The positioning rod 42 positions the moving frame 41 to keep it stable during rise and fall. When the moving frame 41 rises and falls, it drives the gear 45 to slide on the rack 46. When the first cylinder 43 drives the moving frame 41 to the appropriate position, the gear 45 meshes with the rack 46, placing the mold in the flipping frame 51. The second cylinder 54 is activated, which drives the lifting frame 55 to rise and fall. When the lifting frame 55 rises and falls, it drives the two left and right hinge rods 57 to deflect. When the hinge rods 57 deflect, they drive the two left and right clamping frames 52 to move closer to each other, fixing the mold in the flipping frame 51. The third cylinder 59 is activated, which drives the drive rod 510 to move. The arc frame 511 provides the running trajectory for the lower end of the drive rod 510. When the drive rod 510 moves, it causes the position of the left end connection of the flipping frame 51 to change, thereby causing the flipping frame 51 to flip.
