Description

Technical Field

[0001] This utility model belongs to the field of nonwoven fabric production technology, specifically relating to a nonwoven fabric production device for increasing the density of nonwoven fabric. Background Technology

[0002] Nonwoven fabric is a new type of fabric that does not require a spinning and weaving process, but is directly formed into a web and reinforced into a cloth. It is lightweight, soft, breathable, water-permeable, filtering, warm, absorbent, and mildew-resistant, and is widely used in many fields. Below is some basic information about nonwoven fabric.

[0003] However, existing nonwoven fabrics have insufficient density after production, resulting in poor physical properties, poor abrasion resistance, and poor tensile and bursting strength, leading to poor performance in actual use. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a nonwoven fabric production device that increases the density of nonwoven fabric.

[0005] The technical solution adopted to solve the above-mentioned technical problems is: a nonwoven fabric production device for increasing the density of nonwoven fabric, including a mounting frame, a guide roller assembly rotatably mounted on one end of the inner wall of the mounting frame, a hot pressing equipment box mounted in the middle of the inner wall of the mounting frame, a mounting sliding hole opened at the end of the inner wall of the mounting frame away from the guide roller assembly, two hydraulic rods symmetrically mounted at the top of the inside of the hot pressing equipment box, an assembly plate mounted on the moving end of each of the two hydraulic rods, an electric heating device mounted on the top of the assembly plate, and a heat transfer plate mounted on the bottom of the assembly plate. A linear guide module is installed inside the mounting hole. A bracket is installed on the moving end of the linear guide module. A docking plate is installed at one end of the bracket. Limit frames are symmetrically installed on the inner side of the docking plate. A baffle is hinged to one end of the limit frame. A take-up roller is provided inside the limit frame. An installation groove is opened inside the take-up roller. An electrical control device is installed inside the installation groove. A motor is installed inside the installation groove. A pressure block is slidably installed inside the installation groove. A storage groove is opened on the side of the pressure block. A pressure plate is installed inside the storage groove.

[0006] Furthermore, a rack is installed on the side of the pressure block, and a gear is installed at the output end of the motor that meshes with the rack installed on the side of the pressure block. Through the meshing action between the gear and the rack, the pressure block can be driven to slide by the rotation of the output end of the motor, so that the pressure block can extend or hide in the winding roller as needed.

[0007] Furthermore, a spring is installed on the side of the baffle, one end of which is connected to the side of the limiting frame, and a spring is installed on the side of the pressure plate, one end of which is connected to the side of the storage groove. This allows the baffle and the pressure plate to be reset by the elastic force of the springs, and the pressure plate to hold the non-woven fabric end.

[0008] Furthermore, the hot pressing equipment box has two units, which are symmetrically arranged on the inner wall of the mounting frame with heat transfer plates facing each other. This allows the nonwoven fabric to be hot-pressed through the heat transfer plates that move relative to each other.

[0009] Furthermore, the top of the mounting groove has an opening that matches the size of the pressure block, and the opening direction of the storage groove faces the hot press equipment box. The setting of the opening and orientation allows the pressure block to extend smoothly from inside the take-up roller or slide into the hiding place, and allows the non-woven fabric that is conveyed to be correctly pressed by the pressure plate.

[0010] Furthermore, the heating end of the electric heating device is in contact with the surface of the heat transfer plate, and the electric control device is electrically connected to the motor. The electric heating device heats the heat transfer plate to achieve the temperature for hot pressing, and the motor controls the movement of the pressing block under the control of the electric control device.

[0011] The beneficial effects of this utility model are as follows: (1) This utility model adopts a hot pressing device with relative arrangement. By feeding in non-woven fabric for hot pressing, multiple strands of non-woven fabric are hot pressed into one strand. The effect of hot pressing is to increase the density of non-woven fabric. In turn, by increasing the density of non-woven fabric, the wear resistance of non-woven fabric is enhanced, and the tensile strength and bursting strength are improved. In addition, the density and tightness of non-woven fabric have an impact on the appearance, feel and other functions of the fabric. Increasing the density can meet the needs of specific applications. (2) This utility model adopts a combination of a take-up roller and a linear guide module. Combined with the limit frame installed on the bracket installed on the moving end of the linear guide module, the take-up roller can be kept inside the limit frame and moved by the action of the linear guide module, which facilitates the loading, unloading and movement of the take-up roller.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] like Figure 1-6 As shown, a nonwoven fabric production device for increasing the density of nonwoven fabric in this embodiment includes a mounting frame 1. A guide roller group 2 is rotatably mounted on one end of the inner wall of the mounting frame 1. A hot press equipment box 3 is mounted in the middle of the inner wall of the mounting frame 1. A mounting sliding hole 4 is opened at the end of the inner wall of the mounting frame 1 away from the guide roller group 2. Two hydraulic rods 5 are symmetrically mounted on the top of the inside of the hot press equipment box 3. An assembly plate 6 is mounted on the moving end of each of the two hydraulic rods 5.

[0021] An electric heating device 7 is installed on the top of the assembly plate 6. The heating end of the electric heating device 7 is in contact with the surface of the heat transfer plate 8. The heat transfer plate 8 is installed on the bottom of the assembly plate 6. There are two hot press equipment boxes 3, which are symmetrically arranged on the inner wall of the mounting frame 1 with the heat transfer plates 8 facing each other. A linear guide module 9 is installed inside the mounting sliding hole 4. A bracket 10 is installed on the moving end of the linear guide module 9. A docking plate 11 is installed on one end of the bracket 10. A limit frame 12 is symmetrically installed on the inner side of the docking plate 11. The limit frame 12 is arc-shaped. A baffle 13 is hinged to one end of the limit frame 12. A spring connected to the side of the limit frame 12 is installed on the side of the baffle 13. A take-up roller 14 is set inside the limit frame 12. A rotating shaft is installed on the side of the take-up roller 14. By placing the rotating shaft in the limit frame 12, the take-up roller 14 can rotate on a fixed axis, thereby completing the take-up operation.

[0022] The take-up roller 14 has an internal mounting groove 15, and an electrical control device 16 is installed inside the mounting groove 15. A flip-up cover plate is installed at the opening of the mounting groove 15, and the cover plate covers the location of the electrical control device 16 and the motor 17, leaving space for the pressure block 18 at the opening of the mounting groove 15. The motor 17 is installed inside the mounting groove 15, and the electrical control device 16 is electrically connected to the motor 17. The pressure block 18 is slidably installed inside the mounting groove 15. A rack is installed on the side of the pressure block 18. A gear that meshes with the rack on the side of the pressure block 18 is installed at the output end of the motor 17. A storage groove 19 is opened on the side of the pressure block 18. An opening matching the size of the pressure block 18 is opened at the top of the mounting groove 15. The opening direction of the storage groove 19 faces the hot press equipment box 3. A pressure plate 20 is installed inside the storage groove 19. A spring connected to the side of the storage groove 19 is installed on the side of the pressure plate 20.

[0023] The working principle of this embodiment is as follows: When the device is working, the guide roller group 2 guides two sets of non-woven fabrics through the space between two hot pressing equipment boxes 3. The front end of the non-woven fabric is placed inside the receiving groove 19, and the pressure plate 20 presses the non-woven fabric down. After the non-woven fabric is fixed, the internal components of the hot pressing equipment box 3 perform hot pressing on the non-woven fabric. During the hot pressing operation, the electric heating device 7 heats the heat transfer plate 8 and maintains its temperature. Then, under the action of the hydraulic rod 5, the heat transfer plate 8 is driven to move. The two heat transfer plates 8 move towards each other to achieve hot pressing on the non-woven fabric, thereby increasing the density of the non-woven fabric. Subsequently, as the hot pressing action proceeds, the take-up roller 14 rotates synchronously to collect the hot-pressed non-woven fabric. As the take-up roller 14 rotates, the thickness of the non-woven fabric on the take-up roller 14 continuously increases. The electric control device 16 controls the operation of the motor 17. Through the rotation of the output end of the motor 17, the gears rotate and... Engaging with the rack, the pressure block 18 is moved, causing it to slide and retract into the take-up roller 14. Because the pressure plate 20 in the pressure block 18 acts on the front end of the nonwoven fabric, the pressure block 18 is slightly higher than the surface of the take-up roller 14. Therefore, as the thickness of the nonwoven fabric on the take-up roller 14 increases, the nonwoven fabric initially wound on the take-up roller 14 is compacted by the subsequently wound nonwoven fabric. Thus, as the pressure block 18 moves... After being moved back into the take-up roller 14, the front end of the nonwoven fabric can be released from under the pressure plate 20, thus not affecting the nonwoven fabric's release from the take-up roller 14. Furthermore, when replacing the take-up roller 14, it is retracted via the moving end of the linear guide module 9. The take-up roller 14 is restricted by the baffle 13, and the spring on the baffle 13 ensures that the take-up roller 14 is stably positioned inside the limiting frame 12, without affecting its release. The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
