Description

Technical Field

[0001] The utility model relates to the technical field of shuttle-type rotational molding machines, in particular to a multi-arm shuttle-type rotational molding machine. Background Art

[0002] Roto-molding machines are mainly used to produce fuel tanks. In the early stage, powder is filled into the mold on the roto-molding machine, and then the mold is sent to the heating furnace. The powder gradually melts into liquid. The mold is installed on a rotating disk, and the rotating disk is continuously rotated by the rotating mechanism on the roto-molding machine to make the liquid in the mold evenly distributed. After cooling, a fuel tank with a fixed shape is obtained.

[0003] The molds of existing shuttle-type rotational molding machines are usually fixed to the rotating disk with bolts. Workers need to use an escalator to climb to the rotating disk to fix and install the mold. The movement and fixation of the escalator are inconvenient, which takes up a lot of workers' time and makes the mold installation efficiency low.

[0004] Therefore, it is necessary to propose a multi-arm shuttle type rotational molding machine to improve the installation efficiency of the mold. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the escalator arms on the existing shuttle-type rotational molding machine are inconvenient to move and fix, thereby resulting in low mold installation efficiency. A multi-arm shuttle-type rotational molding machine is now provided.

[0006] The technical solution of the utility model is:

[0007] A multi-arm shuttle type rotational molding machine comprises a base, a rotational molding machine and a slide rail are mounted on the base, the rotational molding machine is slidably connected to the base via the slide rail, and the rotational molding machine is mounted with a rotating disk;

[0008] The escalator arm is provided with a first support leg and a second support leg, wherein the first support leg and the second support leg are respectively provided on both sides of the escalator arm and are located at the bottom of the escalator arm;

[0009] A connecting seat is provided on the base, the top of the connecting seat is rotatably connected to the first leg through a pin, and the bottom of the connecting seat is rotatably connected to the base through a bearing;

[0010] A groove for accommodating the escalator arm is provided on the base in a direction parallel to the slide rail, the connecting seat is located in the groove, and an arc-shaped guide rail groove is provided on the base, and the second leg moves in the guide rail groove with the first leg as the center of the circle;

[0011] A folding groove is provided on the escalator arm, and a folding support arm is provided in the folding groove. The support arm can be unfolded from the folding groove to provide support for the escalator arm.

[0012] Furthermore, the guide rail groove is arc-shaped with an arc angle of at least 90 degrees. When the second leg is located at one end of the guide rail groove, the escalator arm is opposite to the rotational molding machine. When the second leg is located at the other end of the guide rail groove, the escalator arm is opposite to the groove.

[0013] Furthermore, the top end of the support arm is rotatably connected to the folding groove, and the bottom end of the support arm contacts the base when the support arm is unfolded, thereby fixing the angle between the escalator arm and the base.

[0014] Furthermore, the steps of the escalator arm are provided with anti-slip pads.

[0015] Furthermore, a barb is provided at the bottom end of the support arm, and an undercut is provided on the base, and the barb can be inserted into the undercut to fix the support arm and the base.

[0016] Furthermore, limit grooves are provided at both ends of the guide rail groove, and the limit grooves are perpendicular to the tangent of the guide rail groove at this location. A flippable limit block is rotatably connected in the limit groove. When the second leg is located at one end of the guide rail groove, the limit block can be flipped into the limit groove, thereby fixing the second leg.

[0017] The utility model discloses a multi-arm shuttle type rotational molding machine. When installing the mold, the escalator arm is first flipped upward from the groove, the first leg rotates relative to the connecting seat, thereby erecting the escalator arm, and then the second leg rotates around the first leg along the guide groove, so that the escalator arm faces the rotational molding machine. At this time, the support arm is taken out of the folding groove, and then the support arm is unfolded. The top end of the support arm contacts the escalator arm, and the bottom end of the support arm contacts the base, thereby achieving the fixing of the inclination angle of the escalator arm, thereby facilitating the staff to climb the escalator arm to the rotating disk and fix the mold on the rotating disk. When the escalator arm needs to be folded, the support arm is first folded into the folding groove, the escalator arm is flipped to align it with the groove, and finally the escalator arm is placed in the groove to achieve the storage of the escalator arm. Compared with the traditional technology, the deployment process and the storage process of the escalator arm do not need to take up much time, and the operation is convenient. The support arm realizes the fixation of the escalator arm. The multi-arm support of the support arm and the escalator arm replaces the traditional external escalator, omitting the process of moving and fixing the escalator, and improving the installation efficiency of the mold.

[0032] like Figure 3 and Figure 4 As shown, the escalator arm 5 is further provided with a first support leg 6 and a second support leg 7. The first support leg 6 and the second support leg 7 are respectively arranged on both sides of the escalator arm 5 and located at the bottom of the escalator arm 5. The first support leg 6 and the second support leg 7 are made of the same material as the escalator arm 5 and can be integrally formed by a mold or fixedly connected by screws.

[0033] A connecting seat 8 is provided on the base 1. The top of the connecting seat 8 is rotatably connected to the first leg 6 via a pin, and the bottom of the connecting seat 8 is rotatably connected to the base 1 via a bearing.

[0034] like Figure 5 and Figure 6 As shown, a groove 9 for accommodating the escalator arm 5 is provided on the base 1 in a direction parallel to the slide rail 3. The connecting seat 8 is located in the groove 9, specifically at one end of the groove 9. An arc-shaped guide rail groove 10 is provided on the base 1. The second support leg 7 moves in the guide rail groove 10 with the first support leg 6 as the center of the circle.

[0035] like Figure 7 As shown, a folding groove 11 is provided on the escalator arm 5 , and a folding support arm 12 is provided in the folding groove 11 . The support arm 12 can be unfolded from the folding groove 11 to provide support for the escalator arm 5 .

When the second support leg 7 is located at one end of the guide rail groove 10, the escalator arm 5 is opposite to the rotational molding machine 2. When the second support leg 7 is located at the other end of the guide rail groove 10, the escalator arm 5 is opposite to the groove 9.

[0037] Preferably, the top end of the support arm 12 is rotatably connected to the folding groove 11 via a pin, and when the support arm 12 is unfolded, the bottom end of the support arm 12 contacts the base 1, thereby fixing the angle between the escalator arm 5 and the base 1.

[0038] Preferably, the steps of the escalator arm 5 are provided with anti-skid pads 13 to increase the friction of the steps and prevent workers from slipping.

[0039] Preferably, a barb 14 is provided at the bottom end of the support arm 12, and an undercut 15 is provided on the base 1.

[0040] Preferably, both ends of the guide rail groove 10 are provided with a limit groove 16, and the limit groove 16 is perpendicular to the tangent of the guide rail groove 10 at this location. A reversible limit block 17 is rotatably connected in the limit groove 16. When the second leg 7 is located at one end of the guide rail groove 10, the limit block 17 can be flipped into the limit groove 16, thereby fixing the second leg 7.

As an optional method, the limit block 17 and the limit groove 16 can be set at one end of the guide rail groove 10 where the second leg 7 is located only when the escalator arm 5 is facing the rotational molding machine 2.

[0041] During operation, when installing the mold, first flip the escalator arm 5 upward from the groove 9, rotate the first leg 6 relative to the connecting seat 8, so that the escalator arm 5 is erected, and then the second leg 7 is rotated around the first leg 6 along the guide groove 10, so that the escalator arm 5 faces the rotational molding machine 2, and at this time, the arm 12 is taken out from the folding groove 11, and then the arm 12 is unfolded, the top end of the arm 12 contacts the escalator arm 5, and the bottom end of the arm 12 contacts the base 1, thereby fixing the inclination angle of the escalator arm 5, making it convenient for the staff to climb the escalator arm 5 to the rotating disk 4, and then rotate it. The mold is fixedly installed on the disk 4. When the escalator arm 5 needs to be folded up, the support arm 12 is first folded into the folding groove 11, the escalator arm 5 is turned over to align it with the groove 9, and finally the escalator arm 5 is placed into the groove 9 to achieve the storage of the escalator arm 5. Compared with the traditional technology, the deployment process and the storage process of the escalator arm 5 do not take up much time, and the operation is convenient. The support arm 12 realizes the fixation of the escalator arm 5. The multi-arm support of the support arm 12 and the escalator arm 5 replaces the traditional external escalator, omitting the process of moving and fixing the escalator, and improving the installation efficiency of the mold.

[0042] Example 2:

[0043] like Figure 8 、 Figure 9 and Figure 10 As shown, the similarities between this embodiment and the first embodiment are not repeated here. The difference is that the escalator arms 5 on the base 1 are symmetrically arranged on both sides of the rotational molding machine 2, so that workers can work from both sides of the rotational molding machine 2 at the same time.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. In other words, any equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the technical scope of the present invention.
