Description

Technical Field

[0001] The utility model relates to the technical field of packaging devices, and in particular to a packaging and packaging device for a three-way catalytic converter. Background Art

[0002] A three-way catalytic converter is a device used for automobile exhaust treatment, also known as a three-way catalytic converter. It is mainly used to reduce and convert harmful gases in automobile exhaust, especially carbon monoxide (CO), nitrogen oxides (NOx) and hydrocarbons (HC). In order to reduce the influence of physical collision, high temperature, corrosion and other factors on the carrier, a liner is often set outside the carrier. The three-way catalytic converter packaging and wrapping device is a device that wraps a fixed liner on the outer surface of the catalyst.

[0003] The existing three-way catalytic converter packaging and wrapping device is: first, the carrier and the gasket are pressed into the lower shell mold together, and then the left upper shell mold and the right upper shell mold are rotated in turn to wrap the gasket. After the wrapping is formed, the left upper shell mold and the right upper shell mold are rotated out of the carrier and taken out to complete the wrapping work.

[0004] Although this can achieve automated packaging and wrapping of the three-way catalytic converter, the following problems still exist: when the thickness of the product and the diameter of the gasket combination are incompatible with the mold in the wrapping device, it is necessary to replace the entire lower shell mold, the upper left mold, and the upper right mold, which makes the mold replacement process very cumbersome and reduces production efficiency.

[0028] like Figure 1 to Figure 6 As shown, this embodiment proposes a three-way catalytic converter packaging and wrapping device, the structure of which includes a fixing frame 1.

[0029] In this embodiment, the first fixed mold 41 and the second fixed mold 42 are detachably arranged on both sides of the lower side of the fixed frame 1 along the X-axis direction, and the first movable mold 51 and the second movable mold 52 are arranged on both sides of the upper side of the fixed frame 1 along the X-axis direction. The first sliding structure is arranged between the fixed frame 1 and the first movable mold 51, and is used to move the first movable mold 51 relative to the fixed frame 1 along the X-axis direction. The second sliding structure is arranged between the fixed frame 1 and the second movable mold 52, and is used to move the second movable mold 52 relative to the fixed frame 1 along the X-axis direction. The first driving structure is arranged on the fixed frame 1 to drive the first movable mold 51. The second driving structure is arranged on the fixed frame 1 to drive the second movable mold 52. A top block 2 is also arranged between the first fixed mold 41 and the second fixed mold 42, and the third driving structure is arranged on the fixed frame 1 to drive the top block 2 to move along the Z-axis direction.

[0030] The first sliding structure in this embodiment includes a sliding rail 12, which is fixedly arranged on the fixed frame 1, and a sliding groove 121 is arranged in the sliding rail 12, and the sliding groove 121 is a "convex"-shaped structure. A sliding member 511 slidingly connected to the sliding groove 121 is fixed at the lower end of the first movable mold 51, and the second sliding structure is the same as the first sliding structure. Such a design ensures that the first movable mold 51 and the second movable mold 52 move smoothly relative to the fixed frame 1, ensures that the first movable mold 51 and the second movable mold 52 will not slide and deviate, and ensures the quality of mold closing.

[0031] The first fixed mold 41 in this embodiment includes a connecting portion 412 and a shaping portion 413, and the mounting groove 11 is arranged on the fixing frame 1. The connecting portion 412 is connected and fixed to the mounting groove 11 by bolts, so as to facilitate the direct disassembly and replacement of the first positioning mold. The shaping groove 4131 is arranged on the shaping portion 413, and the cross section of the shaping groove 4131 is an arc-shaped structure, so as to facilitate the installation of the wrapping gasket on the three-way catalytic converter. The lifting ear 411 is fixedly arranged on the side of the shaping portion 413 away from the shaping groove 4131, so as to facilitate the transportation of the first positioning mold. The first fixed mold 41 has the same structure as the second fixed mold 42. When the thickness of the product and the diameter of the gasket combination are incompatible with the mold in the wrapping device, the first fixed mold 41 and the second fixed mold 42 are disassembled from the fixing frame 1 by bolts, and then the original first fixed mold 41 and the second fixed mold 42 are transported away by the lifting ear 411, and finally the new first fixed mold 41 and the second fixed mold 42 are placed on the fixing frame 1 and installed and fixed.
