They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] See also Figures 1 to 10 The casing end sealing device comprises a cutter mechanism, two clamping mechanisms, and a fixing frame, wherein:

[0038] The cutter mechanism is connected to the fixed frame, and the cutter mechanism includes a cutter assembly 1 and a cutter drive assembly 3. The cutter assembly 1 includes a hot cutter 101 and a cutter holder. The hot cutter 101 is connected to the cutter holder. The hot cutter 101 is used to thermally cut the sleeve. The cutter drive assembly 3 is connected to the cutter assembly 1 to drive the cutter assembly 1 to extend in the vertical direction; two clamping mechanisms 2 are respectively arranged on opposite sides of the hot cutter 101, and the two clamping mechanisms 2 are respectively used to clamp the opposite ends of the sleeve 16.

[0039] The hot cutter 101 in this example can generate heat. A heating wire can be installed in the hot cutter 101. The resistance heating effect of the heating wire is used to convert the electrical energy flowing through the coil into thermal energy, so that the heating wire is heated to a high temperature state. When the heating wire is heated to a sufficiently high temperature, the hot cutter 101 can be heated to a temperature sufficient to melt or cut through an object, thereby achieving cutting.

[0040] When using the sleeve end sealing device of this example, a long sleeve is clamped by two clamping mechanisms 2. Then, under the drive of the cutter drive assembly 3, the hot cutter 101 moves downward until it contacts the middle of the long sleeve and cuts it off. The long sleeve is cut into two sections, and the sleeve end cut by the hot cutter 101 can be melted and sealed.

[0041] Referring to the figure, the knife holder includes a horizontal plate 102 and a vertical plate 103. The vertical plate 103 is connected to the lower part of the horizontal plate 102.
