[0020] In order to make the technical means, technical features, purpose of the utility model and technical effects achieved by the utility model easier to understand, the utility model is further explained below with reference to specific illustrations.

[0021] Example 1:

[0022] like Figure 1 and Figure 2 The figure shows the structure of the water-blocking tape longitudinal wrapping mold of the leak-proof bag of the present invention.

[0023] The water-blocking tape longitudinal wrapping mold of the leak-proof bag of this embodiment includes an upper mold 1, a lower mold 3 and a limit seat 4. The upper mold 1 is fixedly connected to the lower mold 3, the upper mold 1 is fixed to the upper end of the lower mold 3, and the limit seat 4 is fixed to the lower mold 3. The left and right sides of the water-blocking tape longitudinal wrapping mold are respectively provided with a mold outlet 5 and a mold inlet 2, and the mold outlet 5 is connected to the mold inlet 2.

[0024] like Figure 3 The figure shows the structure diagram of the upper half mold of the present invention.

[0025] The upper half mold 1 shown is provided with a conical feed channel 6 and a circular discharge channel 9. The feed channel 6 is opened on one side of the mold inlet 2, and the discharge channel 9 is opened on one side of the mold outlet 5. The feed channel 6 is connected to the discharge channel 9, and the discharge channel 9 is a sizing area through which the water-blocking tape passes.

[0026] like Figure 4 Shown is a schematic structural diagram of the lower half mold of the present invention.

[0027] After the lower half mold 3 shown is fixedly connected to the upper half mold 1, a complete, annular discharge channel 9 is formed. A triangular support platform 7 is fixed in the lower half mold 3. The height of the support platform 7 corresponds to the height of the discharge channel 9, which facilitates the water-blocking tape to enter the discharge channel 9. The support platform 7 plays a role in supporting the water-blocking tape, ensuring that the water-blocking tape remains flat before entering the discharge channel 9 in the sizing area, thereby increasing the integrity and flatness of the longitudinal coating of the water-blocking tape.

[0028] like Figure 5 and Figure 6 As shown, this is a schematic structural diagram of the limit seat of the present invention.

[0029] The limit seat 4 shown is fixed on the lower half mold 3, and the limit seat 4 is fixed on the outside of the mold inlet 2. A limit slot 8 is provided on the limit seat 4. The height of the limit slot 8 is basically flush with the height of the support platform 7. Before entering the mold inlet 2, the water-blocking tape first passes through the limit slot 8 and then enters the mold inlet 2. The limit slot 8 prevents the water-blocking tape from deflecting during the coating process, thereby avoiding leakage.

[0030] 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.
