Description

Technical Field

[0001] This utility model relates to the field of blow molding machines, specifically to a flexible anti-rotation mechanism for blow molding machines. Background Technology

[0002] The blow molding machine is equipped with a water distributor and an air distributor. The water distributor is located below the air distributor, and both consist of a fixed part and a rotating part. Since the external water and air are static inputs, but the distributors require dynamic output during actual use, the rotating parts of both distributors are driven to rotate during machine operation. The fixed parts of both distributors need to be fixed. A sealing ring is used to seal the dynamic and static parts between the fixed and rotating parts. Existing anti-rotation mechanisms for separating the dynamic and static parts of the distributors are rigid connections. After fixing the fixed parts with these mechanisms, they become almost completely immobile. However, the machining and assembly of the various parts on the existing distributors makes it difficult to ensure that the fixed and rotating parts are perfectly coaxial. When the rotating part rotates, the fixed part, being completely immobile, cannot compensate for the slight misalignment between it and the rotating part. Consequently, the sealing ring between the fixed and rotating parts is subjected to extreme forces and is easily worn, leading to water leakage from the water distributor and air leakage from the air distributor. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a flexible anti-rotation mechanism for blow molding machines that can improve the service life of the dynamic and static sealing rings in the water distributor and air distributor of blow molding machines.

[0004] To solve the above problems, the technical solution adopted by this utility model is: a flexible anti-rotation mechanism for a blow molding machine, characterized in that it includes: two anti-rotation columns, a lower flexible connecting plate, and an upper flexible connecting plate. The structure of the lower flexible connecting plate includes: a middle fixed plate and two lower end plates, the two lower end plates being located on the left and right sides of the middle fixed plate respectively. A lower flexible plate is respectively provided between the two lower end plates and the middle fixed plate. The two lower end plates are respectively connected to one end of the lower flexible plate on their respective sides, and the other ends of the two lower flexible plates are respectively connected to the middle fixed plate. Locking holes are provided on the two lower end plates respectively. The structure of the upper flexible connecting plate includes: two upper end plates and one upper flexible plate, the two upper end plates being... The upper flexible plate is not connected to both ends of the upper flexible plate. The upper plate located below is provided with a locking hole. Both the lower and upper flexible plates are long strips and are respectively provided with a stiffening structure to reduce the rigidity of the plates. The lower ends of the two anti-rotation columns are respectively fixed to the base of the blow molding machine frame. The fixing part of the water distributor in the blow molding machine is fixed to the middle fixing plate of the lower flexible connecting plate. The two lower end plates of the lower flexible connecting plate are respectively fixed to the top of the two anti-rotation columns by bolts passing through their locking holes. The upper end plate located below the upper flexible connecting plate is connected to the fixing part of the gas distributor by bolts passing through its locking holes. The upper end plate located above the upper flexible connecting plate is fixed to the top of the blow molding machine frame.

[0005] Furthermore, in the aforementioned flexible anti-rotation mechanism for the blow molding machine, the stiffness-reducing structure consists of several notches spaced alternately along the length of the flexible plate on both sides, causing the remaining portion of the flexible plate to form a serpentine, meandering shape. The depth of the notches is not less than half the width of the flexible plate.

[0006] Furthermore, in the aforementioned flexible anti-rotation mechanism for the blow molding machine, the stiffness-reducing structure can also be: a stiffness-reducing elongated hole arranged along the length of the flexible plate is provided in the middle of the flexible plate. The length of the stiffness-reducing elongated hole is not less than 2 / 3 of the length of the flexible plate, and the width of the stiffness-reducing elongated hole is not less than 1 / 2 of the width of the flexible plate.

[0007] Furthermore, in the aforementioned flexible anti-rotation mechanism of the blow molding machine, the two locking holes on the lower flexible connecting plate are elongated holes.

[0008] Furthermore, in the aforementioned flexible anti-rotation mechanism for the blow molding machine, the locking hole on the lower upper end plate is an elongated hole, and the upper end plate is welded and fixed to the blow molding machine frame.

[0009] Furthermore, in the aforementioned flexible anti-rotation mechanism for blow molding machines, the middle fixed plate is a flange plate.

[0010] The advantages of this utility model are as follows: The flexible anti-rotation mechanism uses a flexible lower connecting plate that combines rigidity and flexibility to fix the fixed part of the water distributor, and a flexible upper connecting plate that combines rigidity and flexibility to fix the fixed part of the gas distributor. When the rotating parts of the two distributors rotate, the flexible connecting plate can effectively prevent the fixed part of the distributor from rotating with it, and can also compensate for and reduce the misalignment between the rotating part and the fixed part through slight deformation. This reduces the stress on the sealing ring between the fixed part and the rotating part, making it less prone to wear, thereby improving the working stability of the blow molding machine.

[0016] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0017] like Figure 1 , Figure 2 , Figure 3As shown, the flexible anti-rotation mechanism of the blow molding machine includes: two anti-rotation columns 1, a lower flexible connecting plate 2, and an upper flexible connecting plate 3. The structure of the lower flexible connecting plate 2 includes: a middle fixed plate 4 and two lower end plates 5, which are located on the left and right sides of the middle fixed plate 4, respectively. A lower flexible plate 6 is provided between the two lower end plates 5 and the middle fixed plate 4. The two lower end plates 5 are connected to one end of the lower flexible plate 6 on their respective sides, and the other ends of the two lower flexible plates 6 are connected to the middle fixed plate 4. Locking holes 9 are provided on the two lower end plates 5. The structure of the upper flexible connecting plate 3 includes: two upper end plates 7 and one upper flexible plate 8, which are connected to both ends of the upper flexible plate 8, located on the lower... The upper end plate 7 of the square is provided with a locking hole 9; the lower flexible plate 6 and the upper flexible plate 8 are both long strips and are respectively provided with a stiffening structure that can reduce the rigidity of the plate. The lower ends of the two anti-rotation columns 1 are respectively fixed to the base of the blow molding machine frame 12. The fixing part of the water distributor 13 in the blow molding machine is fixed to the middle fixing plate 4 of the lower flexible connecting plate 2. The two lower end plates 5 of the lower flexible connecting plate 2 are respectively fixed to the top of the two anti-rotation columns 1 by bolts passing through their upper locking holes 9. The upper end plate 7 of the upper flexible connecting plate 3 located at the bottom is connected to the fixing part of the gas distributor 14 by bolts passing through its upper locking holes 9. The upper end plate 7 of the upper flexible connecting plate 3 located at the top is fixed to the top of the blow molding machine frame 12.

[0018] In this embodiment, the stiffness-reducing structure consists of several notches 10 spaced alternately and sequentially along the length of the flexible plate on both sides, resulting in a serpentine, meandering shape for the remaining portion of the flexible plate. Five notches 10 are provided on the lower flexible plate 6, and eight notches 10 are provided on the upper flexible plate 8. By providing the notches 10, the stiffness of the plate can be reduced, increasing its ductility and thus making it more flexible. To further reduce the stiffness of the plate, the depth of the notches 10 is not less than half the width of the flexible plate.

The length of the stiffness-reducing elongated hole 11 is not less than 2 / 3 of the length of the flexible plate, and the width of the stiffness-reducing elongated hole 11 is not less than 1 / 2 of the width of the flexible plate. After setting the stiffness-reducing elongated hole 11, the stiffness of the plate can be reduced by reducing the connection part of the flexible plate.

[0020] For ease of adjustment, the two locking holes 9 on the lower flexible connecting plate 2 are elongated holes.

[0021] In this embodiment, the locking hole 9 on the lower upper end plate 7 is an elongated hole, and the upper end plate 7 is welded and fixed to the blow molding machine frame 12. In practical applications, the upper end plate 7 can also be provided with locking holes, so that the upper end plate 7 and the blow molding machine frame 12 can be fixed together by bolts.

[0022] To facilitate the fixing of the water distributor 13, the middle fixing plate 4 is set as a flange plate with a large round hole in the middle and bolt holes around the perimeter.
