Description

Technical Field

[0001] This invention relates to the field of oil-absorbing felt pressing technology, and in particular to a pressing mechanism for producing multi-layer oil-absorbing felt. Background Technology

[0002] Oil-absorbing felts are made from inert polypropylene using a melt-blown process. They effectively absorb and retain liquids. The absorbent products are wrapped in polypropylene fibers or non-woven fabric treated with a surface-activating agent and sewn together. The outer fabric is extremely tough and durable, possessing strong capillary absorption and excellent adsorption properties. This draws leaked liquid towards the absorbent felt, effectively preventing the spread of the leak. During the production of oil-absorbing felts, a pressing mechanism is used to press and bond the absorbent fabric and non-woven fabric together.

[0003] Currently, in existing technologies, pressing mechanisms use pressing rollers with uniform spacing to press oil-absorbing felt. During the pressing process, the nonwoven fabric is subjected to sudden tensile force when passing through the pressing rollers, which causes excessive tensile force on the nonwoven fabric, resulting in breakage of the textile threads inside the nonwoven fabric and affecting the production efficiency of oil-absorbing felt. Therefore, this invention proposes a pressing mechanism for the production of multi-layer oil-absorbing felt. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing pressing mechanisms, which use pressing rollers with uniform spacing to press oil-absorbing felt. During the pressing process, the nonwoven fabric is subjected to sudden tensile force from the pressing rollers, resulting in excessive tensile force on the nonwoven fabric and causing breakage of the textile threads within the nonwoven fabric, thus affecting the production efficiency of oil-absorbing felt.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pressing mechanism for producing multi-layer oil-absorbing felt, comprising a support base mechanism, on which a pressing mechanism is mounted, and an adjustment mechanism is also mounted on the support base mechanism, the adjustment mechanism driving the pressing mechanism; the support base mechanism comprises two L-shaped support plates, the two L-shaped support plates are arranged in parallel, and a lower slide rail is fixedly connected to the lower end of each of the two L-shaped support plates; the two L-shaped support plates have three evenly distributed mounting holes; a central fixing plate is fixedly connected between the two L-shaped support plates; and a mounting groove is provided on one side of the central fixing plate.

[0006] In at least some embodiments, the pressing mechanism includes six mounting rods, each of which is installed in a mounting hole, and the upper end of each mounting rod is fixedly connected to a mounting sheet metal, with a rotating rod fixedly connected between two mounting sheet metals.

[0007] In at least some embodiments, a pressing roller is fixedly connected to each of the rotating rods, the pressing rollers being located above the L-shaped support plate, and a mounting base is fixedly connected to the lower end of each of the rotating rods, with a support wheel rotatably mounted inside the mounting base.

[0008] In at least some embodiments, each of the mounting rods is equipped with a support spring located between the mounting base and the L-shaped support plate, and the support wheel is located below the L-shaped support plate.

[0009] In at least some embodiments, the adjustment mechanism includes a drive motor, a motor bracket is mounted on the outside of the drive motor, and the drive motor is fixed to one side of the lower surface of the central fixing plate via the motor bracket.

[0010] In at least some embodiments, the output shaft of the drive motor is fixedly connected to a bidirectional lead screw, one end of which engages with two mating sleeves, one end of which is fixedly connected to a connecting rod, and both ends of the connecting rod are fixedly connected to side support blocks, which are slidably installed in the lower slide rail.

[0011] In at least some embodiments, the two side support blocks are arranged in three steps, the upper surfaces of the two side support blocks are in close contact with the lower surface of the support wheel, the other end of the bidirectional lead screw is engaged with two movable sleeves, and translation connecting rods are rotatably installed on both sides of the movable sleeves, and the translation connecting rods are located in the mounting groove.

[0012] In at least some embodiments, a lower connecting member is rotatably mounted on the upper end of the translation link, an upper support plate is fixedly connected to the upper surface of the lower connecting member, the upper support plate is located inside the middle fixed plate, and side connecting rods are rotatably mounted on both sides of the lower surface of the upper support plate, with the lower ends of the side connecting rods rotatably mounted on the fixed plate.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, starting the drive motor drives the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw can drive the connecting rod and the side support block to move horizontally along the lower slide rail, so that the side support block moves to the bottom of the L-shaped support plate. At the same time, the bidirectional lead screw will also drive the movable sleeve to move in the opposite direction of the connecting rod along the bidirectional lead screw. This can push the upper support plate to rotate around the side connecting rod through the translation link, so that the upper support plate rises. This achieves the effect of adjusting the distance between the upper support plate and the pressing roller, thus adjusting the pressing thickness of the oil-absorbing felt.

[0014] 2. In this invention, when the side support block moves horizontally along the lower slide rail, the stepped arrangement of the side support block will push the mounting rod to rise or fall within the mounting hole, thereby making the three pressing rollers arranged in a stepped manner, which facilitates the pressing of the oil-absorbing felt and prevents the textile threads in the non-woven fabric from breaking during the pressing process.

Detailed Implementation

[0017] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0019] In existing technologies, absorbent products are typically encased in a layer of polypropylene fiber or nonwoven fabric treated with a surface-activating agent and sewn together. This outer layer is extremely tough and durable, possessing strong capillary absorption capacity and resulting in exceptional absorbency. This absorbs leaked liquid and directs it to the absorbent cotton, effectively preventing the spread of the leak. However, the production process of absorbent felts requires a pressing mechanism to bond the absorbent fabric and nonwoven fabric together. This pressing mechanism uses press rollers with uniform spacing to press the absorbent felt. During the pressing process, the absorbent felt is subjected to sudden tensile forces from these rollers, causing excessive tension on the nonwoven fabric and leading to breakage of the internal threads. This negatively impacts the production efficiency of absorbent felts. Therefore, the objective of this invention is at least as follows: by activating the adjustment mechanism 300, the side support block 301 is moved to below the L-shaped support plate 101. At the same time, the bidirectional lead screw 305 drives the upper support plate 309 to rotate around the side connecting rod 308, causing the upper support plate 309 to rise. This achieves the effect of adjusting the distance between the upper support plate 309 and the pressing roller 203, thereby adjusting the pressing thickness of the oil-absorbing felt. When the side support block 301 moves horizontally along the lower slide rail 103, it contacts the pressing mechanism 200, which facilitates the pressing of the oil-absorbing felt. This prevents the textile threads in the nonwoven fabric from breaking during the pressing process.

[0020] Example, according to Figures 1-7 This invention provides a pressing mechanism for producing multi-layer oil-absorbing felt, comprising a support base mechanism 100, on which a pressing mechanism 200 is mounted, and an adjustment mechanism 300 is also mounted on the support base mechanism 100, the adjustment mechanism 300 driving the pressing mechanism 200; as shown. Figure 3 As shown, the support base mechanism 100 includes two L-shaped support plates 101, which are arranged in parallel. Each of the two L-shaped support plates 101 has a lower slide rail 103 fixedly connected to its lower end. The two L-shaped support plates 101 have three evenly distributed mounting holes 102. A middle fixing plate 104 is fixedly connected between the two L-shaped support plates 101. A mounting groove 105 is provided on one side of the middle fixing plate 104.

[0021] like Figure 4As shown, the pressing mechanism 200 includes six mounting rods 204, each mounted in a mounting hole 102. Each mounting rod 204 has a mounting sheet metal 201 fixedly connected to its upper end. A rotating rod 202 is fixedly connected between two mounting sheet metals 201. A pressing roller 203 is fixedly connected to each rotating rod 202, located above the L-shaped support plate 101. A mounting seat 206 is fixedly connected to the lower end of each rotating rod 202, and a support wheel 207 is rotatably mounted within the mounting seat 206. A support spring 205 is installed on the mounting rod 204. The support spring 205 is located between the mounting base 206 and the L-shaped support plate 101. The support wheel 207 is located below the L-shaped support plate 101. When the side support block 301 moves horizontally along the lower slide rail 103, the side support block 301 is arranged in a stepped manner, which will push the mounting rod 204 to rise or fall within the mounting hole 102. This achieves the three pressing rollers 203 being arranged in a stepped manner, which facilitates the pressing of the oil-absorbing felt. This prevents the textile threads in the non-woven fabric from breaking during the pressing process.

[0022] like Figures 5-7As shown, the adjustment mechanism 300 includes a drive motor 302, with a motor bracket 303 mounted on the outside of the drive motor 302. The drive motor 302 is fixed to one side of the lower surface of the central fixing plate 104 via the motor bracket 303. A bidirectional lead screw 305 is fixedly connected to the output shaft of the drive motor 302. One end of the bidirectional lead screw 305 engages with two mating sleeves 306. A connecting rod 307 is fixedly connected to one end of the mating sleeves 306. Side support blocks 301 are fixedly connected to both ends of the connecting rod 307. The side support blocks 301 are slidably installed in the lower slide rail 103. The two side support blocks 301 are arranged in a three-step shape. The upper surfaces of the two side support blocks 301 are in close contact with the lower surface of the support wheel 207. The other end of the bidirectional lead screw 305 engages with two movable sleeves 304. Translation connecting rods 311 are rotatably installed on both sides of the movable sleeves 304. The translation connecting rods 311 are located in the mounting groove 105. A lower connector 310 is rotatably mounted on the upper end. An upper support plate 309 is fixedly connected to the upper surface of the lower connector 310. The upper support plate 309 is located inside the middle fixed plate 104. Side connecting rods 308 are rotatably mounted on both sides of the lower surface of the upper support plate 309. The lower ends of the side connecting rods 308 are rotatably mounted on the fixed plate 104. When the drive motor 302 is started, it drives the bidirectional lead screw 305 to rotate. The rotation of the bidirectional lead screw 305 drives the connecting rod 307 and the side support block 301 along... The lower slide rail 103 moves horizontally, causing the side support block 301 to move below the L-shaped support plate 101. At the same time, the bidirectional lead screw 305 drives the movable sleeve 304 to move in the opposite direction of the connecting rod 307 along the bidirectional lead screw 305. This allows the upper support plate 309 to be pushed to rotate around the side connecting rod 308 via the translation link 311, causing the upper support plate 309 to rise. This allows for adjustment of the distance between the upper support plate 309 and the pressing roller 203, thereby adjusting the pressing thickness of the oil-absorbing felt.
