[0002] Pre-pressing in the processing of spunlace non-woven fabric is an important step. During the production process of spunlace non-woven fabric, pre-pressing is usually carried out before the mixed fibers form an interwoven structure. The pre-pressed fiber cloth has better formability and stability, providing a good foundation for subsequent high-pressure water flow impact treatment. During the pre-pressing process of the non-woven fabric, it is in close contact with the outer surface of the pre-pressing roller. During long-term continuous pre-pressing work, it will cause wear on the outer surface of the pre-pressing roller, resulting in a decrease in the surface finish of the pre-pressing roller, and further affecting the pre-pressing effect. Therefore, it is necessary to regularly maintain and service the pressing roller used for non-woven fabric pre-pressing processing.

[0003] In traditional spunlace non-woven fabric pre-pressing machinery, the pre-pressing roller is rotationally connected to the machinery through bearings and connected to the driving mechanism through a coupling. When replacing the roller body of the pre-pressing roller, the disassembly of the roller body of the pre-pressing roller is troublesome. It is necessary to disassemble multiple sets of couplings and bearings. The disassembly is troublesome and requires the operation of special maintenance tools. The overall weight of the roller body is relatively large, and it is necessary to rely on a hoisting machine for auxiliary operation, resulting in too high a difficulty in replacing the roller body of the pre-pressing roller.

The push cylinder connecting plate 402 is fixedly connected to the push rod of the pre-pressing push cylinder 3. The two support frame guides 401 are respectively slidably connected to the two longitudinal guide rods 101 to play a guiding role. Under the action of the pre-pressing push cylinder 3, a downward pulling force is applied to the elevating support frame 4, so that the non-woven fabric pre-pressing roller 9 can better apply a squeezing force to the upper surface of the non-woven fabric conveying mechanism 2.

[0029] In the embodiment of the present disclosure, a roller mounting opening 403 is formed on the right end plate of the lifting support frame 4. The roller mounting opening 403 is rotatably connected to the roller guide sleeve 6 through a bearing. The roller guide sleeve 6 is of a cylindrical structure, and two guide sleeve guide openings 601 with a rectangular cross-section are formed on the inner surface of the roller guide sleeve 6. The axis of the roller guide sleeve 6 is parallel to the upper surface of the non-woven fabric pre-pressing frame 1. The roller guide sleeve 6 is rotatably connected to the roller mounting opening 403 through a bearing, which plays a supporting role for the roller guide sleeve 6 and fixes the roller guide sleeve 6 in the axial and radial directions.

[0030] Embodiment 2, on the basis of Embodiment 1, a right plug-in convex block 701 is fixedly connected to the left end surface of the right positioning end plate 7. A end plate guide rod 703 is perpendicularly welded to the right end of the right positioning end plate 7. Two guide rod convex plates 704 are machined on the outer surface of the end plate guide rod 703. A fastening push spring 702 is fixedly connected to the right end surface of the right positioning end plate 7. The fastening push spring 702 is sleeved on the end plate guide rod 703. The end plate guide rod 703 is slidably connected to the roller guide sleeve 6. The two guide rod convex plates 704 are respectively slidably connected to the two guide sleeve guide openings 601. A cylindrical left plug-in convex block 801 is fixedly connected to the middle of the right surface of the left positioning end plate 8. The left plug-in convex block 801 is inserted into the left end of the non-woven fabric pre-pressing roller 9. The right end of the non-woven fabric pre-pressing roller 9 is inserted into the right plug-in convex block 701. Under normal conditions, the right positioning end plate 7 is supported by the fastening push spring 702 between the right positioning end plate 7 and the roller guide sleeve 6. A leftward thrust is applied to the right positioning end plate 7 through the action of the fastening push spring 702. The two ends of the non-woven fabric pre-pressing roller 9 are connected to the right plug-in convex block 701 and the left plug-in convex block 801, which plays a supporting role for the non-woven fabric pre-pressing roller 9. When replacing the non-woven fabric pre-pressing roller 9, the right positioning end plate 7 is pushed to the right to increase the distance between the right plug-in convex block 701 and the left plug-in convex block 801, so that the non-woven fabric pre-pressing roller 9 is disengaged from the right plug-in convex block 701 and the left plug-in convex block 801, and the non-woven fabric pre-pressing roller 9 can be disassembled from the pre-pressing device. The non-woven fabric pre-pressing roller 9 is of a hollow structure, which reduces the weight of the non-woven fabric pre-pressing roller 9 and the difficulty of replacing the non-woven fabric pre-pressing roller 9, and the roller replacement work can be completed without using any additional devices.

[0031] Working principle of this embodiment: First, the spunlace non-woven fabric is assisted in transportation by the non-woven fabric conveying mechanism 2, and the spunlace non-woven fabric is pushed towards the pre-pressing device, so that the non-woven fabric passes behind the non-woven fabric pre-pressing roller 9. Then, the non-woven fabric is wound by the winding mechanism. The lifting support frame 4 is pulled downward by the pre-pressing push cylinder 3, so that the non-woven fabric pre-pressing roller 9 increases the extrusion pressure on the non-woven fabric. The left positioning end plate 8 and the non-woven fabric pre-pressing roller 9 are driven to rotate by the roller driving member 5 to realize the rolling of the non-woven fabric. After the rolling device works for a certain period of time, since the non-woven fabric pre-pressing roller 9 is in a high-intensity working state and its outer surface is worn, the equipment is stopped. The right positioning end plate 7 is pushed to the right, so that the fastening push spring 702 is compressed. The right positioning end plate 7 moves to the right, increasing the distance between the right insertion convex block 701 and the left insertion convex block 801, controlling the lateral movement of the non-woven fabric pre-pressing roller 9, and separating the non-woven fabric pre-pressing roller 9 from the right insertion convex block 701 and the left insertion convex block 801, thus completing the disassembly of the right positioning end plate 7. After the outer surface of the right positioning end plate 7 is processed, it is installed in the right insertion convex block 701 and the left insertion convex block 801 again, thus completing the roll change work of the pre-pressing device.
