Description

Technical Field

[0001] This utility model relates to the field of flexible pressing technology, specifically a flexible pressing mechanism for a liquid-absorbing core layer. Background Technology

[0002] A liquid-absorbing core is a material layer with special functions, primarily responsible for absorbing, storing, and transporting liquids. It has wide applications in various fields. Liquid-absorbing cores typically utilize capillary action, porous structures, and the material's inherent hydrophilicity to achieve liquid absorption and transport. Liquid-absorbing cores are usually manufactured using a flexible pressing method. Flexible pressing allows for uniform pressure distribution, reducing localized stress concentrations compared to rigid pressing. This effectively prevents damage such as cracking and deformation during the pressing process, ensuring the integrity of the liquid-absorbing core structure.

[0003] In existing flexible pressing mechanisms for absorbent core layers, the spring, as a key component providing the pressing force, is typically designed with a fixed elastic force. Its basic structure generally involves installing the spring at a specific position within the pressing mechanism, with one end fixed to the main frame and the other end connected to the pressing head or plate. When the pressing mechanism operates, the spring is initially compressed to a certain degree, generating a fixed elastic force. This force is transmitted to the absorbent core layer through the pressing head or plate, achieving the pressing operation. However, different types of absorbent core layers, due to differences in materials, thickness, density, and other factors, have varying requirements for pressing pressure. During production, factors such as batch differences in raw materials and adjustments to production processes necessitate appropriate adjustments to the pressing pressure. A spring with a fixed elastic force cannot meet this dynamic adjustment requirement, thus limiting production flexibility. Utility Model Content

[0004] The purpose of this invention is to provide a flexible pressing mechanism for the liquid-absorbing core layer, to solve the problem mentioned in the background art where, during the production process, the pressing pressure needs to be appropriately adjusted due to factors such as batch differences in raw materials and adjustments to the production process. However, springs with fixed elasticity cannot meet the needs of such dynamic adjustments, thus limiting the flexibility of production.

[0005] To solve the above problems, this utility model provides the following technical solution: a flexible pressing mechanism for a liquid-absorbing core layer, comprising a frame and a pressing part:

[0006] The frame has a pressing platform at the bottom and a telescopic cylinder at the top. The pressing part is located inside the frame and has a lifting frame at the bottom output end of the telescopic cylinder. Several sliding rods are vertically slidably arranged around the lifting frame. The bottom of each sliding rod is equipped with a pressure plate. Several sliding rods are connected to the same pressure plate. Springs are nested around the sliding rods. The bottom of each spring abuts against the top of the pressure plate. An adjusting frame is located inside the lifting frame. The bottom of the adjusting frame abuts against the top of the spring. The adjusting frame moves up and down to adjust the spring force.

[0007] By adopting the above technical solution, a telescopic cylinder can be used to drive the lifting frame to rise and fall, thereby moving the slide rod and pressure plate up and down to achieve the pressing operation of the liquid-absorbing core layer. At the same time, by adjusting the spring force by moving the adjusting frame up and down, the pressing mechanism can be adapted to various production requirements, improving the versatility and applicability of the equipment, avoiding excessive compression damage to the liquid-absorbing core layer, and adapting to the pressing needs of liquid-absorbing core layers of different thicknesses and materials.

[0008] Preferably, the pressing part also has a rotating groove formed at the center of the inside of the adjusting frame, and an adjusting cylinder is rotatably embedded inside the rotating groove, the adjusting cylinder being rotatably connected to the adjusting frame.

[0009] By adopting the above technical solution, the adjusting drum can be rotated, and the adjusting frame can be driven to move up and down by utilizing the rotational connection between the adjusting drum and the adjusting frame.

[0010] Preferably, the four slide rods pass vertically through the adjusting frame and are vertically slidably connected to the adjusting frame, and the spring is located between the adjusting frame and the pressure plate.

[0011] By adopting the above technical solution, the stability of the slide bar during the lifting process can be guaranteed, so that the pressure plate can move up and down smoothly to perform the pressing operation. At the same time, the spring is located between the adjusting frame and the pressure plate, which can effectively transmit the adjusting effect of the adjusting frame on the spring to the pressure plate, so as to achieve flexible pressing.

[0012] Preferably, the pressing part also has a rubber ring embedded in the top of the adjusting frame, and the adjusting cylinder abuts against the rubber ring.

[0013] By adopting the above technical solution, the elasticity and friction of the rubber ring can be used to increase the friction between the adjusting drum and the adjusting frame, preventing the adjusting drum from rotating on its own without human operation, and ensuring the stability and accuracy of the spring force adjustment.

[0014] Preferably, the pressing part also has anti-slip teeth arranged around the outer side of the adjusting cylinder.

[0015] By adopting the above technical solution, the anti-slip teeth can increase the friction between the hand and the adjusting drum when rotating the adjusting drum, making it easier and more stable for the operator to rotate the adjusting drum.

[0016] Preferably, the pressing part also has a threaded rod fixedly installed at the bottom of the lifting frame, and a threaded groove is vertically opened at the center of the inner part of the adjusting drum. The threaded rod passes vertically through the threaded groove and is threadedly nested with the adjusting drum.

[0017] By adopting the above technical solution, when the adjusting drum is rotated, the rotational motion of the adjusting drum can be converted into the vertical linear motion of the adjusting frame by utilizing the threaded nesting connection between the threaded rod and the adjusting drum, thereby achieving precise adjustment of the spring force and improving the adjustment accuracy and reliability of the pressing mechanism.

[0018] Preferably, the top of the slide bar is provided with a limit block and abuts against the top of the lifting frame.

[0019] By adopting the above technical solution, it is possible to prevent the slide bar from falling off the lifting frame during the up-and-down sliding process, ensuring the connection stability between the slide bar and the lifting frame, and thus ensuring the normal operation and pressing effect of the pressure plate during the pressing process.

[0020] Compared with existing technologies, the advantages of this invention are as follows: By incorporating a pressing section, a telescopic cylinder can be used to drive the lifting frame to rise and fall, thereby moving the slide rod and pressure plate up and down to achieve the pressing operation of the liquid-absorbing core layer. Simultaneously, by adjusting the spring force through the up-and-down movement of the adjusting frame, the pressing mechanism can adapt to various production requirements, improving the versatility and applicability of the equipment, avoiding excessive compression damage to the liquid-absorbing core layer, and accommodating the pressing needs of liquid-absorbing core layers of different thicknesses and materials.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a flexible pressing mechanism for a liquid-absorbing core layer, comprising a frame 1 and a pressing part 2.

[0031] A pressing platform 101 is provided at the bottom of the frame 1, and a telescopic cylinder 102 is provided at the top of the frame 1. A cylinder is a device that converts the energy of compressed air into mechanical energy. The working principle of a cylinder is based on the mechanical movement achieved by the propulsion of compressed air. The above is existing technology and will not be elaborated further below. When selecting a model, its power should be selected to suit the needs of the device to ensure that the object to be driven is driven. The pressing part 2 is located inside the frame 1. The pressing part 2 has a lifting frame 201 located at the bottom output end of the telescopic cylinder 102. Several sliding rods 20 are vertically slidably arranged around the lifting frame 201. 3. A pressure plate 204 is provided at the bottom of the slide rod 203. Several slide rods 203 are connected to the same pressure plate 204. Springs 205 are nested around the outside of the slide rods 203. The bottom of each spring 205 abuts against the top of the pressure plate 204. An adjusting frame 206 is provided inside the lifting frame 201. The bottom of the adjusting frame 206 abuts against the top of the springs 205. The adjusting frame 206 moves up and down to adjust the elasticity of the springs 205. The lifting frame 201 can be driven to rise and fall by the telescopic cylinder 102, which in turn drives the slide rods 203 and the pressure plate 204 to move up and down to achieve the pressing operation of the liquid-absorbing core layer. At the same time, the elasticity of the springs 205 can be adjusted by moving the adjusting frame 206 up and down. By adjusting the tension of the springs 205, the pressing mechanism can be adapted to various production requirements, improving the versatility and applicability of the equipment, avoiding excessive compression damage to the liquid-absorbing core layer, and adapting to the pressing needs of liquid-absorbing core layers of different thicknesses and materials.

[0032] Example 2

[0033] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a flexible pressing mechanism for a liquid-absorbing core layer, including a pressing part 2.

[0034] A rotating groove 207 is provided at the center of the inside of the adjusting frame 206. An adjusting cylinder 209 is rotatably embedded inside the rotating groove 207. The adjusting cylinder 209 is rotatably connected to the adjusting frame 206. By rotating the adjusting cylinder 209, the adjusting frame 206 can be moved up and down by utilizing the rotatable connection between the adjusting cylinder 209 and the adjusting frame 206.

[0035] Four sliding rods 203 pass vertically through the adjusting frame 206 and are vertically slidably connected to the adjusting frame 206. Spring 205 is located between the adjusting frame 206 and the pressure plate 204.

[0036] This ensures the stability of the slide bar 203 during the lifting process, allowing the pressure plate 204 to move smoothly up and down for pressing operations. Meanwhile, the spring 205 is located between the adjusting frame 206 and the pressure plate 204, effectively transmitting the adjusting action of the adjusting frame 206 on the spring 205 to the pressure plate 204, thus achieving flexible pressing.

[0037] A rubber ring 208 is embedded in the top of the adjusting frame 206. The adjusting drum 209 abuts against the rubber ring 208. The elasticity and friction of the rubber ring 208 can be used to increase the friction between the adjusting drum 209 and the adjusting frame 206, preventing the adjusting drum 209 from rotating on its own without human operation, and ensuring the stability and accuracy of the spring force adjustment of the spring 205.

[0038] A ring of anti-slip teeth 211 is provided on the outer side of the adjusting drum 209. When the adjusting drum 209 is rotated, the anti-slip teeth 211 can increase the friction between the hand and the adjusting drum 209, making it easier and more stable for the operator to rotate the adjusting drum 209.

[0039] A threaded rod 202 is fixedly installed at the bottom of the lifting frame 201. A threaded groove 210 is vertically opened at the center of the inner part of the adjusting cylinder 209. The threaded rod 202 passes vertically through the threaded groove 210 and is threadedly nested with the adjusting cylinder 209. When the adjusting cylinder 209 is rotated, the rotational motion of the adjusting cylinder 209 can be converted into the vertical linear motion of the adjusting frame 206 by utilizing the threaded nesting connection between the threaded rod 202 and the adjusting cylinder 209. This enables precise adjustment of the elastic force of the spring 205 and improves the adjustment accuracy and reliability of the pressing mechanism.

[0040] A limit block is provided at the top of the slide bar 203 and abuts against the top of the lifting frame 201. This can prevent the slide bar 203 from falling off the lifting frame 201 during the up and down sliding process, ensuring the connection stability between the slide bar 203 and the lifting frame 201, thereby ensuring the normal operation and pressing effect of the pressure plate 204 during the pressing process.

[0041] Working Principle: First, the absorbent core layer to be pressed is placed on the pressing table 101 at the bottom of the frame 1. The telescopic cylinder 102 is activated, and its output end drives the lifting frame 201 to descend. The lifting frame 201, through the slide rod 203, moves the pressure plate 204 downwards until the pressure plate 204 contacts the absorbent core layer and the pressing operation begins. During the pressing process, the spring 205 acts as a buffer and adjusts the pressure. When the pressure plate 204 contacts the absorbent core layer, if the pressure is too high, the spring 205 will be compressed, thereby reducing the pressure of the pressure plate 204 on the absorbent core layer and preventing excessive compression that could damage it, thus achieving flexible pressing. If it is necessary to adjust the elasticity of the spring 205 to accommodate the pressing requirements of absorbent core layers of different thicknesses and materials, the operator can rotate the adjusting drum 209. The anti-slip teeth 211 on the outer side of the adjusting drum 209 increase the contact area between the hand and the adjusting drum 209. The friction between the adjusting drum 209 and the adjusting frame 201 makes the rotation operation easier and more stable. The threaded groove 210 inside the adjusting drum 209 is threadedly nested with the threaded rod 202 at the bottom of the lifting frame 201. When the adjusting drum 209 rotates, its rotational motion is converted into the vertical linear motion of the adjusting frame 206. The vertical movement of the adjusting frame 206 changes the compression degree of the spring 205, thereby adjusting the elastic force of the spring 205. At the same time, the rubber ring 208 embedded at the top of the adjusting frame 206 abuts against the adjusting drum 209. The elasticity and friction of the rubber ring 208 increase the friction between the adjusting drum 209 and the adjusting frame 206, preventing the adjusting drum 209 from rotating on its own without human intervention, thus ensuring the stability and accuracy of the spring force adjustment of the spring 205. In addition, the limiting block at the top of the sliding rod 203 abuts against the top of the lifting frame 201, preventing the sliding rod 203 from sliding off the lifting frame 201 during the vertical movement. The upper part detaches, ensuring the connection stability between the slide bar 203 and the lifting frame 201, thereby ensuring the normal operation and pressing effect of the pressure plate 204 during the pressing process. After the pressing is completed, the telescopic cylinder 102 drives the lifting frame 201 to rise, thereby causing the pressure plate 204 to leave the liquid-absorbing core layer, making it convenient to remove the pressed liquid-absorbing core layer.
