Abstract
Description
Technical Field
[0001] The invention relates to the technical field of non-woven fabric production and processing equipment, and in particular to polypropylene non-woven fabric production and processing equipment. Background Art
[0002] Polypropylene has many excellent properties, making it an ideal raw material for spunbond nonwovens. From the perspective of chemical structure, polypropylene has a regular molecular chain and a high degree of crystallinity, which gives it good physical and mechanical properties, such as high strength and hardness. In the spunbond process, polypropylene chips are melt-extruded at high temperatures, and their good thermal stability ensures the smooth spinning process. In the packaging field, it can effectively block external moisture and dust, provide reliable protection for packaged items, and extend the shelf life of items.
[0003] In the production process of spunbond nonwovens, the slitting machine is an important link between production and finished products. It is responsible for cutting the large-area nonwovens produced according to specific size specifications to meet the needs of different application scenarios. The performance and ease of operation of the slitting machine have a crucial impact on the efficiency of the entire production process and product quality.
[0004] However, the current traditional non-woven fabric slitting machines have some urgent problems to be solved during actual use. Especially in the feeding process of the roller used to place the non-woven fabric, the existing slitting machine needs to remove the roller from the equipment as a whole for feeding operations. This design has negative effects in actual production. On the one hand, this overall disassembly feeding method makes the operation process cumbersome and inefficient. Each feeding involves the disassembly and reinstallation of a large number of fixed parts, which requires workers to spend a lot of time and energy. In a large-scale industrial environment, frequent feeding operations will significantly reduce production efficiency, increase the production time per unit product, and cannot meet the growing market demand.
[0005] On the other hand, during the disassembly process, the key components such as the bearings and sleeves of the connecting rollers are easily subjected to external impact and friction, resulting in a decrease in their accuracy. When reinstalling, if the installation is not in place, the rollers will vibrate during operation, further aggravating the wear of the components. In the long run, this will not only significantly shorten the service life of the equipment and increase the equipment renewal costs of the enterprise, but may also frequently cause slitting machine failures, leading to production stagnation, increased maintenance costs and downtime.
[0006] Therefore, it is necessary to provide a polypropylene nonwoven fabric production and processing equipment to solve the above technical problems. Summary of the invention

[0016] Compared with the related art, the polypropylene non-woven fabric production and processing equipment provided by the present invention has the following beneficial effects: (1) The present invention provides a polypropylene non-woven fabric production and processing equipment. The present invention replaces the traditional roller with an unwinding part. Inner support plates are hinged at the ends of the extrusion arm and the support arm. The spacing angles between the extrusion arm and the support arm are both 90 degrees to form a cross pile. When the inclination angles of the extrusion arm and the support arm relative to the axis of the rotating shaft gradually increase, the spacing between the two corresponding inner support plates increases. In actual use, it is only necessary to insert the inner cylinder wrapped with the non-woven fabric into the outer sides of the multiple inner support plates, and the inner cylinder loading process can be quickly completed by rotating the adjustment sleeve. In this way, there is no need to disassemble the unwinding part body like in the traditional way, making the entire operation process more convenient and efficient. The non-disassembly installation design has a low mechanical failure rate and higher safety, and is suitable for the loading needs of inner cylinders of different models and inner diameters.
[0017] (2) The present invention provides a polypropylene non-woven fabric production and processing equipment. Two inner tubes with non-woven fabrics wound on them can be independently installed on the two unwinding parts of the present invention. The non-woven fabrics wound on the two inner tubes can be respectively wound on two different winding rollers through positioning rollers, so that the slitting requirements of two groups of non-woven fabrics can be completed at the same time, and the two groups do not interfere with each other. This situation is suitable for inner tubes with narrow widths. At the same time, when the length of the inner tube is wider and not greater than the spacing between the two unwinding parts, the inner tube can be lifted to between the two unwinding parts, and the slider can be moved horizontally until it contacts the limit block, driving the inner support rod to enter the inner side of the inner tube, and then the position of the slider is locked by the locking bolt, and finally the hand wheel is turned to drive the inner support rod to contact the inner wall of the inner tube and close to the strip baffle. Therefore, in this embodiment, it is further possible to realize separate slitting operations for non-woven fabric materials of width angles, and the scope of application is further expanded.
[0018] (3) The present invention provides a polypropylene non-woven fabric production and processing equipment. The present invention can judge whether the inner support rod is firmly fixed by the same way that the outer wall of the inner support rod contacts the strip baffle. Without considering the self-weight of the inner tube and the non-woven fabric wound thereon, the fixing force of the inner support rod on the inner tube is almost the same. For some inner tubes made of paper materials, it is not easy to cause them to deform and does not affect the concentricity of the inner tube. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0021] In addition, the terms used below are defined based on the functions of the present invention and may differ depending on the intention or custom of the user or operator. Therefore, these terms are defined based on the entire contents of this specification.
[0022] See also Figure 1-Figure 7 The polypropylene non-woven fabric production and processing equipment described in the present invention comprises side panels 1 placed parallel to each other on a working floor, the two side panels 1 are positioned and fixed by a truss 11, a plurality of mounting holes are opened in the side panel 1, an inner wall of the side panel 1 is provided with an axis frame in the mounting holes, an unwinding portion 2, a positioning roller 3, a slitting blade head 4 and a winding roller 5 are sequentially installed on the axis frame from left to right, wherein a control cabinet 6 is installed on the side wall of one side panel 1, a motor driving the winding roller 5 is mounted in the control cabinet 6, and the driving connection method between the motor and the winding roller 5 can be referred to. Figure 3 As shown, this embodiment will not be described in detail. The slitting head 4 is composed of a crossbar and a cutting head, and is a common movable slitting head on the market, which can adjust the slitting width of the non-woven fabric according to actual slitting requirements; There are two unwinding parts 2 and two winding rollers 5 installed in the two side plates 1. The unwinding parts 2 are arranged concentrically side by side, and the winding rollers 5 are arranged at the upper and lower ends of the two side plates 1 respectively. In this case, two inner cylinders with non-woven fabrics can be independently installed on the two unwinding parts 2. The non-woven fabrics wound on the two inner cylinders can be wound on two different winding rollers 5 through the positioning rollers 3, respectively, so that the slitting requirements of two groups of non-woven fabrics can be completed at the same time, and the two groups do not interfere with each other. This situation is suitable for inner cylinders with narrow widths. The specific winding path of the non-woven fabric can be referred to. Figure 1 As shown, when performing the slitting operation, it is only necessary to wind the free end of the non-woven fabric around the winding roller 5 according to the above path, adjust the slitting blade head 4 to the specified position, and start the motor in the control cabinet 6 to achieve the slitting operation; The unwinding part 2 includes a rotating shaft 21 rotatably mounted on the shaft frame. The rotating shaft 21 can rotate on the shaft frame. In order to increase the smoothness of the rotation of the two, multiple sets of bearings can be added at the connection between the two, and lubricating grease can be applied to the bearings. An outer collar frame 22 is welded in sequence starting from one end of the rotating shaft 21 close to the inner side of the side plate 1. Generally, there are two outer collar frames 22, both of which are made of high-strength steel. The outer ring of the outer collar frame 22 is hinged with a support arm 23 at equal angles along the path. The outer wall of the rotating shaft 21 and the outer wall of the area between the outer collar frame 22 and the side plate 1 are provided with a connecting thread 20. The outer collar frame 22 is provided with an adjusting sleeve 24 through thread matching in the area where the connecting thread 20 is provided. When the adjusting sleeve 24 is rotated while keeping the rotating shaft 21 stationary, the adjusting sleeve 24 can move axially relative to the rotating shaft 21. The outer ring of the adjusting sleeve 24 is rotatably mounted with a rotating ring 25. Figure 4 As shown, in actual production, the area on the outer wall of the adjusting sleeve 24 for placing the rotating ring 25 may be provided with a concave circular groove of a certain depth, and the concave circular groove is used to horizontally limit the rotating ring 25. Of course, this can also be achieved by providing a horizontal baffle on the outer side wall of the adjusting sleeve 24. The rotating ring 25 is composed of two semicircular rings fixed by bolts, which is convenient for installing it to the outer side wall of the adjusting sleeve 24; The outer ring of the rotating ring 25 is hinged with a pressing arm 26 at equal angles along the path. The pressing arm 26 and the supporting arm 23 are of the same size and have the same initial inclination angle relative to the axis of the rotating shaft 21. In the initial state, the position of the adjusting sleeve 24 is located as follows: Figure 4At the L end shown in the figure, the inclination angles of the squeezing arm 26 and the supporting arm 23 relative to the axis of the rotating shaft 21 are the smallest, and the position of the rotating shaft 21 is kept unchanged. After the adjusting sleeve 24 is rotated, the adjusting sleeve 24 can drive the rotating ring 25 to move axially, that is, from the L end to the R end, and the inclination angles of the squeezing arm 26 and the supporting arm 23 relative to the axis of the rotating shaft 21 gradually increase; In order to facilitate the rotation of the adjustment sleeve 24, a hand wheel 241 is installed at a concentric position of the outer ring of the adjustment sleeve 24, and the outer surface of the hand wheel 241 is provided with anti-slip grooves, that is, the operator can drive the adjustment sleeve 24 to rotate together by holding the hand wheel 241; The extrusion arm 26 and the support arm 23 are hinged with an inner support plate 27 at the end. The angle between the support arms 23 on a single outer ring frame 22 and the angle between the extrusion arms 26 on the rotating ring 25 are preferably 90°. In this state, the positions of the inner support plates 27 are cross-shaped, and the corresponding two inner support plates 27 are parallel to each other. As mentioned above, when the inclination angles of the extrusion arm 26 and the support arm 23 relative to the axis of the rotating shaft 21 gradually increase, the corresponding spacing between the two inner support plates 27 increases. In actual use, it is only necessary to insert the inner cylinder wrapped with non-woven fabric into the outer side of multiple inner support plates 27, and the loading process of the inner cylinder can be quickly completed by rotating the adjustment sleeve 24. Under this method, there is no need to disassemble the unwinding part 2 body like the traditional method, which makes the entire operation process more convenient and efficient. The non-disassembly installation design has a low mechanical failure rate and higher safety, and is suitable for the loading needs of inner cylinders of different models and inner diameters.
[0023] See also Figure 5 A support frame 211 is symmetrically installed on the outer side of the two side plates 1, a bearing sleeve 212 is installed on the inner side of the support frame 211, and the bearing sleeve 212 is inserted into the outer wall of the rotating shaft 21. The rotating shaft 21 is further supported externally by the bearing sleeve 212, thereby increasing the stability of the rotating shaft 21 during working rotation.
[0024] In another embodiment, see Figure 5As shown, a polygonal positioning groove 217 is provided at the center of the end surface of one end of the outer side of the side plate 1 near the rotating shaft 21, and a plug hole 213 is symmetrically provided on the outer side of the support frame 211. A cross rod 214 is inserted into the plug hole 213, and a flat plate 215 is welded to the end of the cross rod 214 facing the polygonal positioning groove 217. A polygonal positioning block 216 is welded to the center of the inner wall of the flat plate 215, and the polygonal positioning block 216 and the polygonal positioning groove 217 are a matching structure, and the two have the same shape. In this embodiment, the polygonal positioning block 216 and the polygonal positioning groove 217 are illustrated by taking a quadrilateral as an example. When the inner cylinder wound with the non-woven fabric is installed to Before unwinding the roll section 2, first move the cross rod 214 to drive the flat plate 215 and the polygonal positioning block 216 to move toward the polygonal positioning groove 217 until the polygonal positioning block 216 is inserted into the polygonal positioning groove 217. The two cooperate to lock the position of the rotating shaft 21, and at this time, one of the inner support plates 27 should be parallel to the horizontal plane. In this state, it is convenient to rotate the adjustment sleeve 24 to adjust the inner support plate 27, that is, the operator does not need to manually keep the rotating shaft 21 still, and the operation is more convenient. When the inner cylinder with the non-woven fabric wound is installed, move the cross rod 214 again to drive the polygonal positioning block 216 to separate from the polygonal positioning groove 217; Furthermore, a magnet is symmetrically embedded at one end of the cross rod 214 facing away from the socket 213, and the support frame 211 is a magnetic metal component. On the basis of the above, when the cross rod 214 is moved to drive the polygonal positioning block 216 to separate from the polygonal positioning groove 217, the cross rod 214 can be directly moved to one end thereof to be in close contact with the side wall of the support frame 211, and the magnet will be adsorbed on the support frame 211, thereby ensuring that the cross rod 214 will not shake or loosen, and will not interfere with the rotation of the rotating shaft 21.
[0025] In another embodiment, see Figure 3-Figure 6 The end surface of the inner support plate 27 is provided with a slide groove 271, and a slider 272 is installed in the slide groove 271. The slider 272 can slide along the inner wall of the slide groove 271. A locking bolt 273 is installed on the slider 272. When the locking bolt 273 is turned, one end of the locking bolt 273 will contact the inner side of the slide groove 271, and the position of the slider 272 is locked by the friction force. The end of the locking bolt 273 can be embedded with a silicone block. The silicone block contacts the inner wall of the slide groove 271, which can increase the locking stability of the slider 272. A limit block 270 is installed on the inner side of the slide groove 271 near its end. The maximum sliding distance of the slider 272 relative to the slide groove 271 is to slide until it hits one side of the limit block 270. The limit block 270 and the slide groove 271 are fixed with high-strength bolts, and the two are detachable. A hinge seat 274 is symmetrically installed on the upper end surface of the slider 272, and a swing arm 275 is rotatably installed in each hinge seat 274. An inner support rod 276 is inserted at the end of the swing arm 275. A strip baffle 277 is symmetrically installed on the upper end surface of the inner support plate 27, and the end surface of the strip baffle 277 is in an arc shape. When the inner cylinder with non-woven fabric wrapped around it is installed in this way, the inner support rod 276 moves with the inner support plate 27. During the process, the outer wall of the inner support rod 276 directly contacts the inner wall of the inner cylinder, increasing the contact point with it, making the inner cylinder fixed more stable, and it can also be fixed to the inner cylinder with a square inner hole. Similarly, this method can adapt to the slitting work of the two groups of non-woven fabrics mentioned above. At the same time, when the length of the inner tube is wider and not greater than the distance between the two unwinding parts 2, the inner tube can be lifted between the two unwinding parts 2, and the slider 272 can be moved horizontally until it contacts the limit block 270, driving the inner support rod 276 to enter the inner side of the inner tube, and then the position of the slider 272 is locked by the locking bolt 273, and finally the hand wheel 241 is turned to drive the inner support rod 276 to contact the inner wall of the inner tube and close to the strip baffle 277. Therefore, in this embodiment, it is further possible to realize separate slitting operations for non-woven fabric materials of width angles, and the scope of application is further expanded.
[0026] like Figure 7 As shown, an arc groove 261 is provided on the inner wall of the hinge seat 274, and an arc block 262 is installed on the outer wall of the swing arm 275 located in the inner area of the hinge seat 274. A torsion spring 263 is installed between the arc block 262 and the arc groove 261. Under normal conditions, the torsion spring 263 pushes the arc block 262 to be close to one end of the arc groove 261. At this time, there is a certain inclination angle between the corresponding swing arm 275 and the upper end surface of the slider 272, and there is a vertical interval between the strip baffle 277 and the side wall of the swing arm 275. When the hand wheel 241 is turned to install the inner cylinder, the inner support rod 276 can continue to turn the hand wheel 241 after contacting the inner wall of the inner cylinder. When the swing arm 275 is deflected relative to the hinge seat 274 to the strip baffle, the inner support rod 276 can continue to turn the hand wheel 241. 277 stops the rotation of the handwheel 241. In the above process, the arc block 262 deflects correspondingly in the arc groove 261. The arc block 262 compresses the torsion spring 263 with a rebound force, and the rebound force is released through the end of the inner support rod 276 to act on the inner wall of the inner cylinder, thereby achieving the inner clamping of the inner cylinder. Under this method, when installing inner cylinders with different inner diameters, it can be judged in the same way whether they are firmly fixed (that is, the outer wall of the inner support rod 276 conflicts with the strip baffle 277). Without considering the dead weight of the inner cylinder and the non-woven fabric wound around it, the fixing force of the inner support rod 276 on the inner cylinder is almost the same, and it is not easy to cause deformation of the inner cylinder made of some paper materials, thereby affecting the concentricity.
[0027] Furthermore, the outer ring of the inner support rod 276 is wrapped with a rubber sleeve 278, and the surface of the rubber sleeve 278 is evenly spaced with rubber protrusions, and the diameter of the rubber protrusions is 1-3 mm, which increases the friction between the inner support rod 276 and the inner tube.
[0028] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
