Description

Technical Field

[0001] The utility model relates to the field of refrigerator seal processing, and particularly relates to a processing device for a refrigerator seal. Background Art

[0002] At present, refrigerator seals on the market are formed by connecting four completely identical sealing strips end to end to form a rectangular frame. The ends of each sealing strip are cut into 45° inclined planes for easy bonding. The common operation of connecting the ends of the sealing strips is manual operation, which has large errors, poor bonding firmness, and the rectangular frame shape of the straight-angle corner sealing strip after bonding is irregular, affecting the use.

[0003] The Chinese invention patent with the application number 201611014972.1 proposes a processing device for a refrigerator seal, but there are still some deficiencies:

[0004] First, there is no structure for supporting the seal between the installation molds, which may cause the middle section of the seal to collapse under its own weight, resulting in bonding errors and low processing accuracy.

[0005] Second, it only has a length adjustment structure on one side, and the side where the connecting rod is located cannot be adjusted in length, so the applicable range is small. Accordingly, the utility model proposes a processing device for a refrigerator seal to solve the above problems. Summary of the Utility Model

[0006] In order to overcome the above defects in the prior art, the utility model provides a processing device for a refrigerator seal. By setting side support blocks and a central support block, the middle part of the seal is supported to avoid the middle part of the seal from collapsing and ensure the bonding accuracy; the length control in two directions of the mold is realized through two control shafts, and the applicable range is larger.

[0007] Technical Solution

[0008] A processing device for a refrigerator seal includes four molds. Right-angled grooves for placing the seal are provided on the molds. A central support block is arranged between two adjacent molds. A side support block is arranged between the central support block and the mold. Linear grooves for placing the seal are provided on the side support block and the central support block. A telescopic mechanism capable of telescoping is arranged between the central support block and the mold. A control mechanism for driving the telescopic mechanism to telescope is arranged between two opposite central support blocks.

[0009] Further, the control mechanism includes a control shaft that penetrates and is rotatably connected to one of the central support blocks. The other end of the control shaft is threadedly connected to a connecting shaft. The other end of the connecting shaft is fixedly arranged on the central support block opposite to the central support block where the control shaft is located.

[0010] Furthermore, a threaded space is provided in the control shaft, and the threaded space is threadedly connected to the connecting shaft.

[0011] Furthermore, a rotating handle is detachably fixedly provided on one end of the control shaft away from the connecting shaft.

[0012] Furthermore, the telescopic mechanism includes a plurality of limit rods fixedly arranged on the central support block, and the limit rods penetrate through and are fixedly connected to the side support blocks.

[0013] Furthermore, a sliding space is provided inside the limiting rod, a telescopic rod is slidably connected in the sliding space, and the other end of the telescopic rod is fixed to the mold.

[0014] Beneficial Effects

[0015] Compared with the prior art, the utility model has the following beneficial effects: by arranging the side support blocks and the central support blocks, the middle part of the seal is supported to avoid the collapse of the middle part of the seal and ensure the bonding accuracy; the length control of the mold in two directions is realized by two control axes, and the application range is wider.
