Description

Technical Field

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

[0002] Unidirectional elastic nonwoven fabric is a type of nonwoven fabric with unidirectional tensile elasticity. In the medical industry, unidirectional elastic nonwoven fabric is often used as a raw material for products such as bandages, dressings, and masks. In the sportswear industry, unidirectional elastic nonwoven fabric can also be used as a raw material for products such as compression garments and protective gear. In the production process of unidirectional elastic nonwoven fabric, pressing equipment is required to press the nonwoven fabric and elastic material together.

[0003] In existing processes, rolling equipment is often used for rolling. However, most existing rolling equipment does not have an adjustable cutting structure. Due to limitations in processing technology and material alignment accuracy, burrs and misaligned areas will be generated on both sides of the nonwoven fabric and elastic layer after rolling. Therefore, after rolling, special equipment is often needed to cut the unidirectional elastic nonwoven fabric, resulting in more processing steps and additional cutting equipment, which increases production costs and wastes manpower and time.

[0004] Therefore, there is an urgent need to provide a unidirectional elastic nonwoven fabric production equipment to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a unidirectional elastic nonwoven fabric production equipment.

[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a unidirectional elastic nonwoven fabric production equipment is provided, including a base mechanism and an edge trimming mechanism. A gantry mechanism is fixed at the top of the base mechanism. A pressing roller mechanism for pressing materials is provided on the inner side of the gantry mechanism. A pressing roller mechanism for pressing materials is also provided on the inner side of the gantry mechanism.

[0007] The outside of the pressing roller mechanism is provided with an edge trimming mechanism for cutting nonwoven fabric;

[0008] The gantry mechanism is also equipped with a pressure adjustment mechanism for adjusting the pressing force.

[0009] The present invention is further configured such that: the base mechanism includes a base body, a plurality of support feet are fixed at the bottom end of the base body, and shock-absorbing seats are provided at the bottom end of the support feet.

[0010] Through the above technical solutions, the support feet can prevent the base body from contacting the ground, thereby preventing the base body from being worn or corroded by contact with liquids on the ground. The shock-absorbing seat can reduce the vibration of the device during operation and reduce the impact of surrounding vibrations on the device.

[0011] The present invention is further configured such that: the gantry mechanism includes a frame fixed to the base body, the inner walls on both sides of the frame are provided with sliding grooves, the inner side of the frame is also fixed with a bearing, and the top of the frame is fixed with an inner threaded sleeve.

[0012] Through the above technical solution, the bearing can reduce the rotational resistance between the first pressing roller mechanism and the gantry mechanism, while the slide can limit the second pressing roller mechanism, so that the second pressing roller mechanism can move up and down more stably without radial and axial displacement.

[0013] The present invention is further configured such that: the pressing roller mechanism includes a heating roller fixed to the inner ring of the bearing, the other end of the heating roller is provided with a drive motor, and the outer wall of the heating roller is provided with multiple sets of screw grooves.

[0014] Through the above technical solution, a heating rod is provided inside the heating roller, which enables the device to perform hot pressing, the drive motor can drive the heating roller to rotate, and the screw groove can be used to fix the trimming mechanism.

[0015] The present invention is further configured such that: the second pressing roller mechanism includes a slider slidably disposed inside the groove, a connecting frame is fixed on the slider, a second heating roller is rotatably connected to the inner side of the connecting frame, and the second heating roller has multiple annular grooves.

[0016] Through the above technical solution, the second heating roller also has the function of heating, thereby improving the hot pressing effect. The connecting frame can slide along the slide groove, and the opening position of the annular groove corresponds to the position of the screw groove.

[0017] The present invention is further configured such that: the trimming mechanism includes an annular hoop disposed outside the heating roller, an annular cutter is integrally fixed on the annular hoop, and multiple screw holes are also provided on the annular hoop, with fixing screws disposed inside the screw holes.

[0018] The above technical solution provides two trimming mechanisms. The annular clamp is fixed to the screw groove by fixing screws. When the heating roller presses the material, the annular cutter can trim both sides of the material, thereby reducing subsequent processing steps and saving manpower and time. The annular groove can accommodate the trimming mechanism during pressing, avoiding affecting the pressing of the material. Since multiple sets of screw grooves and annular grooves are provided, the operator can install the trimming mechanism in different screw grooves according to the width of the material, thereby changing the spacing of the trimming mechanism, making the device suitable for materials of different specifications.

[0019] The present invention is further configured such that: the pressure regulating mechanism includes a threaded rod threaded to the inner side of the inner threaded sleeve, an adjusting handwheel is fixed to the top end of the threaded rod, a connecting plate is fixed to the bottom end of the threaded rod, a compression spring is fixed to the bottom end of the connecting plate, and a rotating connecting piece is fixed to the bottom end of the compression spring.

[0020] With the above technical solution, when the operator needs to adjust the pressing force between pressing roller mechanism one and pressing roller mechanism two, the adjusting handwheel can be rotated, thereby driving the threaded rod to move down or up along the inner thread sleeve. At this time, the connecting plate will also move down or up, thereby tightening or loosening the pressure spring. When the pressure spring is tightened, the pressure of the pressure spring on pressing roller mechanism two will increase, thereby increasing the pressing force between pressing roller mechanism one and pressing roller mechanism two. Conversely, the pressing force between pressing roller mechanism one and pressing roller mechanism two can be reduced. The bottom end of the rotating connecting piece is rotatably connected to the connecting frame. Therefore, when the operator rotates the adjusting handwheel, the pressure spring will also rotate, thereby avoiding the pressure spring from being subjected to excessive torque.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. By setting up a pressing roller mechanism one, a pressing roller mechanism two, and an edge trimming mechanism, this utility model enables the device to trim the side edges of the material while pressing it, thereby reducing subsequent processing steps;

[0023] 2. By setting up a gantry frame mechanism, a pressing roller mechanism, and a pressure adjustment mechanism, the pressing force of this device can be adjusted, thereby making the device suitable for processing various types and specifications of materials. Attached Figure Description

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0031] Please see Figures 1-5 A unidirectional elastic nonwoven fabric production device includes a base mechanism 1 and an edge trimming mechanism 5. The base mechanism 1 includes a base body 101, and a plurality of support feet 102 are fixed to the bottom end of the base body 101. A shock-absorbing seat 103 is provided at the bottom end of the support feet 102. The support feet 102 can prevent the base body 101 from contacting the ground, thereby preventing the base body 101 from being worn or corroded by contact with liquids on the ground. The shock-absorbing seat 103 can reduce the vibration of the device during operation and reduce the impact of surrounding vibration on the device.

[0032] like Figure 1 and Figure 2 As shown, a gantry mechanism 2 is fixed to the top of the base mechanism 1. The gantry mechanism 2 includes a frame 201 fixed to the base body 101. Slide grooves 202 are provided on both inner walls of the frame 201. A bearing 203 is also fixed to the inner side of the frame 201. An inner threaded sleeve 204 is fixed to the top of the frame 201. The bearing 203 can reduce the rotational resistance between the pressing roller mechanism 1 3 and the gantry mechanism 2. The slide grooves 202 can limit the pressing roller mechanism 2 4, so that the pressing roller mechanism 2 4 can move up and down more stably and will not have radial and axial displacement.

[0033] like Figure 1 and Figure 3As shown, the inner side of the gantry mechanism 2 is provided with a pressing roller mechanism 3 for pressing materials. The pressing roller mechanism 3 includes a heating roller 301 fixed to the inner ring of the bearing 203. The other end of the heating roller 301 is provided with a drive motor 303. The outer wall of the heating roller 301 is provided with multiple sets of screw grooves 302. The heating roller 301 is provided with a heating rod inside, so that the device can perform hot pressing. The drive motor 303 can drive the heating roller 301 to rotate. The screw grooves 302 can be used to fix the trimming mechanism 5.

[0034] like Figure 1 and Figure 3 As shown, the inner side of the gantry mechanism 2 is also provided with a second pressing roller mechanism 4 for pressing materials. The second pressing roller mechanism 4 includes a slider 401 that is slidably disposed inside the slide groove 202. A connecting frame 402 is fixed on the slider 401. A second heating roller 403 is rotatably connected to the inner side of the connecting frame 402. The second heating roller 403 has multiple annular grooves 404. The second heating roller 403 also has the function of heating, thereby improving the hot pressing effect. The connecting frame 402 can slide along the slide groove 202. The opening position of the annular grooves 404 corresponds to the position of the screw groove 302.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, the pressing roller mechanism 3 is externally equipped with a trimming mechanism 5 for cutting nonwoven fabric. The trimming mechanism 5 includes an annular hoop 501 located outside the heating roller 301. An annular cutter 502 is integrally fixed on the annular hoop 501. The annular hoop 501 also has multiple screw holes 503, and fixing screws 504 are installed inside the screw holes 503. There are two trimming mechanisms 5. The annular hoop 501 is fixed to the screw groove 302 by the fixing screws 504. When the heating roller 301 is pressing, the annular cutter 502 can trim both sides of the material, thereby reducing subsequent processing and saving manpower and time. The annular groove 404 can accommodate the trimming mechanism 5 during pressing, avoiding affecting the pressing of the material. Since there are multiple sets of screw grooves 302 and annular grooves 404, the operator can install the trimming mechanism 5 in different screw grooves 302 according to the width of the material, thereby changing the spacing of the trimming mechanism 5, so that the device can be used for materials of different specifications.

[0036] like Figure 1 and Figure 5As shown, the gantry mechanism 2 is also equipped with a pressure adjusting mechanism 6 for adjusting the pressing force. The pressure adjusting mechanism 6 includes a threaded rod 601 threadedly connected to the inner side of the inner threaded sleeve 204. An adjusting handwheel 602 is fixed to the top of the threaded rod 601, and a connecting plate 603 is fixed to the bottom of the threaded rod 601. A compression spring 604 is fixed to the bottom of the connecting plate 603, and a rotating connecting piece 605 is fixed to the bottom of the compression spring 604. When the operator needs to adjust the pressing force between the pressing roller mechanism 1 3 and the pressing roller mechanism 2 4, the adjusting handwheel 602 can be rotated, thereby driving the threaded rod 601 along the inner threaded sleeve. When 204 moves downward or upward, the connecting plate 603 will also move downward or upward, thereby pressing or releasing the compression spring 604. When the compression spring 604 is pressed, the pressure of the compression spring 604 on the second pressing roller mechanism 4 will increase, thereby increasing the pressing force between the first pressing roller mechanism 3 and the second pressing roller mechanism 4. Conversely, it can reduce the pressing force between the first pressing roller mechanism 3 and the second pressing roller mechanism 4. The bottom end of the rotating connecting piece 605 is rotatably connected to the connecting frame 402. Therefore, when the operator rotates the adjusting handwheel 602, the compression spring 604 will also rotate, thereby preventing the compression spring 604 from being subjected to excessive torque.

[0037] In use, the operator can place the tensioned corrugated nonwoven fabric and elastic material between the pressing roller mechanism 3 and the pressing roller mechanism 4, and adjust the pressing force through the pressure regulating mechanism 6. Then, the heating roller 301, the heating roller 403 and the drive motor 303 are turned on. At this time, the drive motor 303 can drive the heating roller 301 to rotate, and roll and heat press the material, thereby pressing the corrugated nonwoven fabric and elastic material. At the same time, the edge trimming mechanism 5 can trim the uneven parts on both sides of the material.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
