[0002] The heat shrink treatment of the automobile latch plastic cover is achieved by utilizing the characteristics of heat shrinkable materials. Heat shrinkable materials are usually processed high molecular polymers. At room temperature, they have a certain shape and size.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Refer to Figure 1-2 As shown, the embodiment of the present invention provides a heat shrink machine for plastic sheathing of mortise locks, comprising a heating unit and a heat shrinking platform 6. The heat shrinking platform 6 is slidably disposed on a frame and is used to place the mortise lock with the plastic sheath. The heating unit comprises a heating port, and the heat shrinking platform 6 is adapted to the heating port. The heat shrinking platform 6 is used to move into the heating port to heat shrink the plastic sheath through the heating unit.

[0023] During use, the operator places the mortise lock with the plastic sheath on the heat shrinking table 6, moves the heat shrinking table 6 to the heating port, and heat shrinks the plastic sheath by heating the heating unit. After the heat shrinking is completed, the heat shrinking table 6 withdraws from the heating port, and the heat-shrinked product is manually removed.

[0024] Refer to Figure 1-3 As shown, the heating unit is composed of two rows of heaters 2, with a gap between the two rows of heaters 2, and the gap is a heating port;

[0025] Specifically, when the heat shrinking table 6 is in the heating port, the two rows of heaters 2 are respectively located above and below the heat shrinking table 6. The upper and lower heaters 2 are heated at the same time to heat shrink the plastic sheath on the heat shrinking table 6, which has higher heat shrinking efficiency, more uniform heating temperature and better effect.

[0026] like Figure 4 As shown, the bottom of the heat shrinking table 6 is a mesh structure, the mesh structure is used to circulate hot air, and a plurality of mold tables 9 are provided on the mesh structure, and the mold tables 9 are used to place the locks with plastic covers;

[0027] Specifically, the latch head is placed in the mold table 9, the plastic sleeve on the latch bracket is not in the mold table 9, and the plastic sleeve is located above the mesh structure and is not blocked by the mold table 9. During the heat shrinkage treatment, the heaters 2 located above and below the plastic sleeve can transfer heat to the plastic sleeve very well, and the heat transfer efficiency is faster.

[0028] like Figure 2 and 4 As shown, the heat shrinking platform 6 is telescopically connected to the frame via a slide rail, and the heat shrinking platform 6 can move along the setting direction of the slide rail. The heat shrinking machine is also provided with a slide cylinder 7, and the heat shrinking platform 6 is connected to the driving end of the slide cylinder 7. The movement of the heat shrinking platform 6 is adjusted by the driving end of the slide cylinder 7;

[0029] Specifically, the slide cylinder 7 adjusts the heat shrink table 6 to enter the heating port for heat shrinkage treatment. After completion, the slide cylinder 7 adjusts the heat shrink table 6 to withdraw from the heating port. It has the function of automatically adjusting the position of the heat shrink table 6 to avoid direct contact between human hands and the heat shrink table 6 and burns.

[0030] like Figure 1 and 2 As shown, the heat shrink machine is also provided with a cooling mechanism, which is used for cooling the lock plastic sheath after heat shrinkage. The cooling mechanism includes a plurality of cooling valves 1 and cooling guns 3. Each cooling gun 3 is connected to a corresponding cooling valve 1 through a pipeline. The cooling valve 1 is a switch for adjusting the gas output of the cooling gun 3. The cooling valve 1 is connected to a pneumatic device through a pipeline, and the pneumatic device supplies air to the cooling gun 3 through the cooling valve 1. Several cooling guns 3 are arranged above the mold table 9. Each mold table 9 is provided with a corresponding cooling gun 3. The air outlet on each cooling gun 3 is oriented toward the position of the corresponding mold table 9, and the cooling gun 3 supplies air to the lock plastic sheath on the corresponding mold table 9.

[0031] During use, the heat-shrunk product exits from the heating port, and the pneumatic equipment provides air source to the cooling valve 1, and the cooling valve 1 blows air to the surface of the heat-shrunk product through the cooling gun 3. The number of cooling guns 3 is consistent with the number of products. A separate cooling gun 3 can blow air to a corresponding product to achieve a rapid cooling effect, making it convenient for personnel to remove the cooled product from the heat-shrinking table 6.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
