DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] See also Figure 1-2 A hydraulic type texturizing machine roller disassembly and assembly machine comprises a chassis 1, a disassembly and assembly platform 2 is provided on the chassis 1, a bracket 3 is provided on the disassembly and assembly platform 2, a cylinder 4 is provided on the bracket 3, a sleeve pressing upper die 5 is connected to the telescopic end of the cylinder 4, a positioning groove 6 is provided on the disassembly and assembly platform 2 just below the sleeve pressing upper die 5, a columnar sleeve pressing lower die 7 is inserted in the positioning groove 6, the sleeve pressing lower die 7 has a T-shaped cross section, and a through positioning hole 8 is provided in the center, the sleeve pressing lower die 7 comprises a columnar rod 701, an end cap 702 connected to one end of the columnar rod, the columnar rod 701 can pass through the step 9, the end faces of the two ends of the end cap 702 are tapered, and the end cap 702 can be placed on the step 9. A groove is provided in the sleeve pressing upper die 7, and the diameter of the groove is the same as the diameter of the columnar rod 701, so that the sleeve pressing upper die 5 can be sleeved on the outer periphery of the sleeve pressing lower die 7 when it descends.

[0022] The working principle of this embodiment is:

[0023] like Figure 3As shown, when the rubber sleeve needs to be pressed out, the column 701 of the sleeve pressing lower die 7 is facing upward, one end of the leather roller is inserted into the column 701 through the positioning hole 8, and then the oil cylinder 4 is controlled to extend to drive the sleeve pressing upper die 5 to descend, and the rubber sleeve 1102 is pushed through the sleeve pressing upper die 5. During the pushing process, the rubber sleeve 1102 moves downward, and the roller 1101 is embedded in the groove of the sleeve pressing upper die 5 until the rubber sleeve 1102 is completely detached from the roller 1101, thereby completing the pressing out of the rubber sleeve.

[0024] like Figure 4 As shown, when the rubber sleeve 1102 needs to be inserted, the lower sleeve pressing mold 7 is turned over so that the end cap 702 faces upward, and then the roller 1101 is inserted into the end cap 702 through the positioning hole 8, and then the rubber sleeve 1102 is placed on the roller 1101, and then the upper sleeve pressing mold 7 is controlled to descend to press the rubber sleeve 1102 onto the roller 1101 to complete the assembly of the leather roller.

[0025] Example 2

[0026] The difference between this embodiment and the first embodiment is that a storage groove is provided on the top of the chassis 1, and an auxiliary column 10 is placed in the storage groove. The diameter of the auxiliary column 10 is the same as the diameter of the column rod 701, and the upper end of the auxiliary column is tapered.

[0027] like Figure 5 As shown, when the rubber sleeve 1102 is put into place, the auxiliary column 10 can also be placed on the roller 1101 so that the auxiliary column 10 is aligned with the roller 1101, and then the rubber sleeve 1102 is put on the auxiliary column 10, and then the rubber sleeve 1102 is squeezed downward by the upper pressing mold 5 and put on the outer periphery of the roller 1101, which solves the problem that the rubber sleeve is easily offset or falls off when it is placed directly on the roller.
