DETAILED DESCRIPTION

[0027] The specific embodiments of the utility model are further described below in combination with the drawings and examples. The following examples are only used to more clearly illustrate the technical scheme of the utility model, and cannot limit the protection scope of the utility model.

[0028] The "top surface", "bottom", "bottom surface" are referenced to the normal use state of the trimming device, and are only used for the convenience of describing the utility model and simplifying the description, and are not used to indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the utility model.

[0029] As shown in Figure 1 and 3 A trimming device for surface-modified non-woven fabric includes a base 1, two stand columns 101 are fixedly connected to the base 1; a support roller 2 is rotatably arranged between the two stand columns 101; a mounting shaft 3 is rotatably arranged between the two stand columns 101; a cutter head 4 has a sleeve part 401, the sleeve part 401 is coaxially sleeved on the outer periphery of the mounting shaft 3, an elastic bushing 7 is arranged between the sleeve part 401 and the mounting shaft 3, and the elastic bushing 7 is sleeved on the outer periphery of the mounting shaft 3; a limiting mechanism is arranged on the mounting shaft 3, and the limiting mechanism is configured to limit the axial displacement of the sleeve part 401 along the mounting shaft 3.

[0030] The trimming machine can be used for cutting and trimming the edges of non-woven fabric. When in use, the non-woven fabric passes between the supporting roller 2 and the mounting shaft 3, and the trimming of the non-woven fabric is performed by the cutter head 4 on the mounting shaft 3. The supporting roller can be provided with a motor to drive the rotation of the supporting roller, so as to realize the conveying of the non-woven fabric. The cutter head 4 rotates synchronously with the supporting roller 2, and the cutting of the non-woven fabric is realized through the mutual extrusion between the cutter head 4 and the supporting roller 2. The deformation of the elastic bushing 7 enables the cutter head 4 to produce displacement perpendicular to the axial direction of the mounting shaft 3. At the same time, the elastic force generated by the extrusion of the elastic bushing 7 is applied to the cutter head, so that the cutter head 4 with different degrees of wear can be in close contact with the outer circumferential surface of the supporting roller 2. Therefore, the cutter head 4 can generate sufficient shearing force on the non-woven fabric, so as to ensure the stable and reliable cutting effect of the cutter head 4 on the non-woven fabric and improve the processing effect of the trimming equipment on the non-woven fabric. The limiting mechanism is fixed on the mounting shaft and is distributed on both sides of the cutter head 4. The limiting mechanism abuts against the end of the sleeve part 401 from both sides, so as to limit the axial movement of the sleeve part 401 along the mounting shaft 3 and realize the positioning of the cutter head 4. This prevents the cutter head 4 from moving along the axial direction of the mounting shaft 3 during the cutting process, so that the cutter head 4 can cut the edges of the non-woven fabric more evenly, and the processing effect of the trimming equipment on the non-woven fabric is further improved.

[0031] Further improvement is that, as shown in Figure 2 The limiting mechanism includes two clamps 6, which are sleeved on the outer periphery of the mounting shaft 3 and clamp the sleeve part 401 from both sides. The two clamps 6 limit the movement of the cutter head 4 from both sides, thereby improving the stability of the installation of the cutter head 4 on the mounting shaft 3.

[0032] Further improvement is that, as shown in Figure 5 The clamp 6 includes two semicircular clamping pieces 601, and the end portions of the two clamping pieces 601 are fixedly connected by a bolt assembly 9. The clamping piece 601 is provided with a flange 602 on the side close to the sleeve part 401, and the side of the flange 602 abutting against the sleeve part 401 is a plane perpendicular to the axial direction of the mounting shaft 3. The bolt assembly 9 is used to fasten and separate the two clamping pieces 601, so as to realize the disassembly and assembly of the clamp 6 on the mounting shaft 3. Therefore, the fixed position of the clamp 6 on the mounting shaft 3 can be adjusted, and the position of the cutter head 4 on the mounting shaft 3 can be adjusted according to the width of the non-woven fabric. In this way, the trimming equipment can be suitable for the processing of non-woven fabrics with different widths, and the practicability of the trimming equipment is improved.

[0033] Further improvement is that, as shown in Figure 4As shown, the two ends of the sleeve part 401 are both circumferentially provided with annular grooves 402, and the annular grooves 402 are provided with lubricating members 8. The annular grooves 402 are arranged to limit the lubricating members 8 and improve the stability of the installation of the lubricating members 8; the lubricating members 8 are used to reduce the friction between the sleeve part 401 and the clamps 6, so that the cutter head 4 can move more smoothly along the axial direction perpendicular to the mounting shaft 3 during the process of extruding the elastic bushing 7, and thus the cutter head 4 can better abut against the supporting roller 2 during rotation; at the same time, the mutual abrasion between the sleeve part 401 and the clamps 6 can be reduced, the reliability of the equipment operation is improved, and the service life of the equipment is prolonged.

[0034] Further improvement is that, as shown in the drawings, Figure 3 The lubricating member 8 is a polytetrafluoroethylene ring, and the lubricating member 8 is inserted and matched with the annular groove 402. The friction coefficient of polytetrafluoroethylene is very low, and it can remain stable within a very wide temperature and load range, and has good self-lubricating property, so that the lubricating member 8 can effectively realize the lubrication between the sleeve part 401 and the clamps 6.

[0035] Further improvement is that, the outer circumferential surface of the mounting shaft 3 and the inner circumferential surface of the sleeve part 401 are both provided with anti-skid lines. The elastic bushing 7 can be made of rubber material to ensure that the elastic bushing 7 has good elasticity, and the anti-skid lines and the elastic bushing 7 can also cooperate with each other to increase the friction between the mounting shaft 3 and the cutter head 4, thereby reducing the probability of relative sliding between the two and reducing the abrasion therebetween.

[0036] Further improvement is that, as shown in the drawings, Figure 1 The top end of the column 101 is provided with a fastening mechanism 5, and the end of the mounting shaft 3 is connected with the fastening mechanism 5 through a bearing. The fastening mechanism 5 is arranged to apply a pressure to the mounting shaft 3 in the direction of the supporting roller 2, so that the cutter head 4 can be closely abutted against the supporting roller 2, and the cutter head 4 can effectively cut the non-woven fabric.

[0037] Further improvement is that, as shown in the drawings, Figure 1 The fastening mechanism 5 includes a guide column 502 vertically and fixedly connected to the column 101, a lifting seat 501 slidingly matched with the guide column 502, a vertically distributed threaded sleeve 504 fixedly connected to the top end of the guide column 502, a stud 503 coaxially and threadedly connected with the threaded sleeve 504, and the bottom end of the stud 503 abuts against the lifting seat 501. The stud 503 and the threaded sleeve 504 cooperate with each other, so that the stud 503 can move in the direction of approaching or away from the supporting roller 2 when the stud 503 rotates, thereby pushing the lifting seat 501 to move along the guide column 502 through the stud 503, so as to adjust the distance between the mounting shaft 3 and the supporting roller 2, and finally adjust the pressure between the cutter head 4 and the supporting roller 2, so as to ensure the effective cutting of the non-woven fabric by the trimming device and improve the processing effect of the non-woven fabric by the trimming device.
