Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing technology, and in particular to a polypropylene nonwoven fabric processing equipment. Background Technology

[0002] Polypropylene nonwoven fabric has many advantages such as light weight, corrosion resistance, and good air permeability, and is widely used in many fields such as medical and health care, agriculture, and industry. In the production and processing of polypropylene nonwoven fabric, it is often necessary to trim the edges to ensure the neatness of the edges of the nonwoven fabric products and meet the requirements of subsequent processing or use. Currently, existing polypropylene nonwoven fabric edge trimming equipment suffers from several drawbacks. Firstly, the cutting blade position adjustment is often inconvenient. When trimming polypropylene nonwoven fabrics of different widths, it is often necessary to disassemble the equipment and replace the corresponding parts, which is cumbersome and reduces processing efficiency. Secondly, the rotational speed coordination between the conveyor roller and the cutting blade is not precise enough, which can easily lead to uneven edges, stretching and deformation of the nonwoven fabric, and other problems that affect product quality. Therefore, we propose a polypropylene nonwoven fabric processing equipment to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a polypropylene nonwoven fabric processing equipment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A polypropylene nonwoven fabric processing device includes a support plate, two vertical plates fixedly installed on the top of the support plate, and a common rotating shaft rotatably mounted between the two vertical plates. A conveying roller for conveying polypropylene nonwoven fabric is fixedly mounted on the rotating shaft. An L-shaped plate is fixedly installed on one side of each vertical plate, and a rotating shaft is rotatably mounted on the inner wall of one side of the L-shaped plate. One end of the rotating shaft passes through the corresponding vertical plate, and an adjusting sleeve is slidably sleeved on the rotating shaft. A cutting blade for trimming the polypropylene nonwoven fabric is fixedly mounted on one side of the adjusting sleeve. An adjusting mechanism is provided between the rotating shaft and the adjusting sleeve.

[0006] Preferably, a fixing plate is fixedly installed on the top of the support plate, and a servo motor is fixedly installed on one side of the fixing plate. The output shaft of the servo motor is fixedly connected to the rotating shaft, and a transmission mechanism is provided between the rotating shaft and the rotary shaft.

[0007] Preferably, the transmission mechanism includes a drive gear and a driven gear. The drive gear is fixedly mounted on the rotating shaft, and the driven gear is fixedly mounted on the rotating shaft. The drive gear meshes with the corresponding driven gear.

[0008] Preferably, the adjustment mechanism includes a movable hole and a movable seat. The top of the rotating shaft has a movable hole, and the movable seat is fixedly installed on the top and bottom inner walls of the adjustment sleeve, and the movable seat is slidably connected to the corresponding movable hole.

[0009] Preferably, the adjustment mechanism further includes a threaded hole, a drive screw, and a rotating plate. The threaded hole is formed on the inner wall of one side of the moving hole. The drive screw is threadedly installed in the threaded hole. One end of the drive screw is rotatably mounted on the moving seat, and the other end of the drive screw extends to the outside of the rotating shaft and is fixedly mounted on the rotating plate.

[0010] Preferably, a rotating groove is provided on one side of the movable seat, an annular groove is provided on the inner wall of the rotating groove, an annular seat is installed on the drive screw, and the annular seat is rotatably connected to the annular groove.

[0011] Preferably, two collection boxes for waste collection are placed on the top of the support plate, and the collection boxes are located below the cutting groove.

[0012] The beneficial effects of this utility model are: 1. By setting an adjustment mechanism, the operator only needs to rotate the rotating plate to drive the drive screw to rotate, which in turn pushes the moving seat, adjusting sleeve and cutting blade to move along the rotating axis, so as to achieve precise adjustment of the cutting blade position. There is no need to disassemble the equipment, the operation is simple and convenient, and it can quickly adapt to the edge cutting requirements of polypropylene non-woven fabrics of different widths, effectively improving processing efficiency. 2. By setting up a transmission mechanism, the power of the rotating shaft is transmitted to the rotating shaft through the meshing of the drive gear and the driven gear, so that the rotating shaft and the rotating shaft rotate synchronously. This ensures that the speed at which the conveyor roller conveys the nonwoven fabric matches the cutting speed of the cutting blade, avoiding problems such as nonwoven fabric stretching and deformation or uneven cutting edges caused by speed mismatch, thus improving product quality.

Detailed Implementation

[0015] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0016] This application discloses a polypropylene nonwoven fabric processing equipment.

[0017] Reference Figure 1-5 A polypropylene nonwoven fabric processing device includes a support plate 101. Two vertical plates 102 are fixedly installed on the top of the support plate 101. The same rotating shaft 103 is rotatably installed between the two vertical plates 102. A conveying roller 104 for conveying polypropylene nonwoven fabric is fixedly installed on the rotating shaft 103. An L-shaped plate 201 is fixedly installed on one side of the vertical plate 102. A rotating shaft 202 is rotatably installed on the inner wall of one side of the L-shaped plate 201. One end of the rotating shaft 202 passes through the corresponding vertical plate 102. An adjusting sleeve 203 is slidably sleeved on the rotating shaft 202. A cutting blade 204 for cutting the edge of polypropylene nonwoven fabric is fixedly installed on one side of the adjusting sleeve 203. An adjusting mechanism is provided between the rotating shaft 202 and the adjusting sleeve 203.

[0018] In this embodiment, two cutting grooves 205 are provided on the outer side of the conveying roller 104, and the cutting blade 204 extends into the corresponding cutting groove 205. This design can accurately limit the cutting path of the cutting blade 204, avoid cutting deviation, and isolate the cutting blade 204 from direct contact with the conveying roller 104, reduce wear on both, and ensure the cutting quality and service life of equipment components.

[0019] In this embodiment, a fixing plate 301 is fixedly installed on the top of the support plate 101, and a servo motor 302 is fixedly installed on one side of the fixing plate 301. The output shaft of the servo motor 302 is fixedly connected to the rotating shaft 103. A transmission mechanism is provided between the rotating shaft 103 and the rotating shaft 202. The servo motor 302 is stably fixed by the fixing plate 301, and the transmission mechanism is used to achieve precise power transmission, ensuring that the conveying and cutting actions are synchronized, and avoiding stretching or jamming during the non-woven fabric conveying process.

[0020] In this embodiment, the transmission mechanism includes a drive gear 303 and a driven gear 304. The drive gear 303 is fixedly mounted on the rotating shaft 103, and the driven gear 304 is fixedly mounted on the rotating shaft 202. The drive gear 303 meshes with the corresponding driven gear 304. The gear meshing transmission method has high transmission efficiency and small error, which can strictly ensure the speed matching between the rotating shaft 103 and the rotating shaft 202, further improving the coordination of the action of the conveying roller 104 and the cutting blade 204, and ensuring the neatness of the cut edge.

[0021] In this embodiment, the adjustment mechanism includes a movable hole 401 and a movable seat 402. The top of the rotating shaft 202 is provided with a movable hole 401. The movable seat 402 is fixedly installed on the top and bottom inner walls of the adjustment sleeve 203, and the movable seat 402 is slidably connected to the corresponding movable hole 401. The sliding cooperation between the movable hole 401 and the movable seat 402 provides a stable movement trajectory for the adjustment sleeve 203, avoiding the shaking of the cutting blade 204 during the adjustment process, and laying the foundation for the accuracy of the position adjustment of the cutting blade 204.

[0022] In this embodiment, the adjustment mechanism also includes a threaded hole 501, a drive screw 502, and a rotating plate 503. The threaded hole 501 is formed on the inner wall of one side of the moving hole 401. The drive screw 502 is installed in the threaded hole 501. One end of the drive screw 502 is rotatably mounted on the moving seat 402, and the other end of the drive screw 502 extends to the outside of the rotating shaft 202 and is fixedly mounted on the rotating plate 503. The threaded transmission adjustment method can realize the fine adjustment of the position of the cutting blade 204. With the convenient operation of the rotating plate 503, the adjustment can be completed without disassembling the equipment, which greatly improves the equipment's adaptability to non-woven fabrics of different widths.

[0023] In this embodiment, a rotating groove is provided on one side of the movable seat 402, and an annular groove is provided on the inner wall of the rotating groove. An annular seat is installed on the drive screw 502, and the annular seat is rotatably connected to the annular groove. The rotational engagement between the annular seat and the annular groove can limit the axial displacement of the drive screw 502, ensuring that the drive screw 502 only pushes the movable seat 402 to move when it rotates, avoiding component offset during the adjustment process and ensuring adjustment accuracy.

[0024] In this embodiment, two collection boxes 6 for waste collection are placed on the top of the support plate 101, and the collection boxes 6 are located below the cutting groove 205. The collection boxes 6 are precisely aligned with the bottom of the cutting groove 205 and can collect the cutting waste in real time.

[0025] The working principle of this utility model is as follows: First, the position of the cutting blade 204 is adjusted according to the width specification of the polypropylene nonwoven fabric to be processed. The operator rotates the rotating plate 503, which drives the drive screw 502 to rotate in the threaded hole 501. Since the drive screw 502 is rotatably connected to the moving seat 402, and the moving seat 402 is slidably connected to the rotating shaft 202 through the moving hole 401, the rotation of the drive screw 502 will push the moving seat 402 to slide in the moving hole 401. The moving seat 402 drives the adjusting sleeve 203 and the cutting blade 204 to move along the length direction of the rotating shaft 202 until the cutting blade 204 moves to the appropriate position, thus achieving the purpose of adjusting the position of the cutting blade 204 according to actual needs. After adjusting the position of the cutting blade 204, the polypropylene nonwoven fabric is passed through the conveying roller 104. The servo motor 302 is started, and the output shaft of the servo motor 302 drives the rotating shaft 103 to rotate. The rotating shaft 103 drives the conveying roller 104 to rotate, and the conveying roller 104 conveys the polypropylene nonwoven fabric forward. At the same time, the drive gear 303 on the rotating shaft 103 drives the driven gear 304 meshing with it to rotate. The driven gear 304 drives the rotating shaft 202 to rotate, and the rotating shaft 202 drives the adjusting sleeve 203 and the cutting blade 204 to rotate synchronously. The cutting blade 204 performs edge trimming on the polypropylene nonwoven fabric during the conveying process. During the edge trimming process, the cutting blade 204 extends into the cutting groove 205 on the conveying roller 104. The cutting groove 205 guides and limits the cutting blade 204 to ensure the neatness of the cut edge. The waste generated by cutting falls into the collection box 6 below under the action of gravity and is collected by the collection box 6.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
