[0002] Non-woven fabric is a multi-functional material with extremely wide applications. It plays an important role in the field of medical and health. Due to its good air permeability and water resistance, it is often used to make disposable products such as surgical gowns, masks, and medical bed sheets. These products not only need to have the ability to isolate bacteria and liquids, but also need to ensure air permeability and comfort. Non-woven fabric just meets these requirements. In agriculture, non-woven fabric is used as a covering material to protect crops from pests and help maintain soil moisture. In addition, it can also be used to make agricultural products such as seed tapes and mulch films, which helps to improve the growth efficiency and yield of crops. With its unique properties and advantages, non-woven fabric plays an irreplaceable role in multiple industries. From medical to agriculture, from home decoration to industry, the application of non-woven fabric almost penetrates into all aspects of daily life. Its environmental protection and functional characteristics make it an indispensable material in modern times. When producing non-woven fabric, it is often necessary to bond multiple layers of non-woven fabric together by hot pressing and bonding.

[0003] The existing authorized publication number is CN220053158U, which discloses a hot pressing and bonding device for multi-layer non-woven fabrics, including a workbench, an unwinding roller, a base frame, a guiding roller, a hot pressing device, a cutting device, a fixing plate, and a lifting type winding device. The unwinding roller is arranged on one side of the workbench, the base frame is arranged on the workbench, the guiding roller is arranged on both sides of the base frame, the hot pressing device is arranged on the base frame, the cutting device is arranged on the base frame and located outside the guiding roller, the fixing plate is arranged on the base frame, and the lifting type winding device is arranged on the fixing plate. The utility model belongs to the technical field of non-woven fabric heat sealing, and specifically refers to a hot pressing and bonding device for multi-layer non-woven fabrics that can automatically lift and unload the wound non-woven fabric, saving time and effort, and at the same time can cut the hot pressed and bonded non-woven fabric. However, when the above hot pressing and bonding device for multi-layer non-woven fabrics performs hot pressing and bonding and winding of non-woven fabric, the first section of non-woven fabric released by the unwinding roller cannot be hot pressed by the hot pressing device and wound onto the winding device. If hot pressing treatment and winding are performed on this section of non-woven fabric, it is necessary for the operator to manually pull the non-woven fabric to pass it through the hot pressing device and wind it onto the winding device, which poses a certain safety hazard to the operator. Therefore, it is necessary to provide a hot pressing and bonding device for multi-layer non-woven fabrics to solve the above problems. Summary of the Utility Model

Two groups of mounting plates are installed inside the U-shaped plate. Sliding blocks are installed at both ends of the mounting plate. The size of the sliding block is adapted to the size of the sliding groove provided on the inner side of the U-shaped plate, and the sliding block is arranged in the sliding groove, so that the mounting plate is installed inside the U-shaped plate.

[0009] As a further solution of the present utility model, two groups of through holes are symmetrically provided on the mounting plate. One wire sleeve is installed in each group of through holes.

[0010] As a further solution of the present utility model, two groups of motors are symmetrically installed on the top of the U-shaped plate. Two groups of through holes are symmetrically provided on the top of the U-shaped plate. The top of the lead screw passes through the through hole and is connected to the motor, so that the lead screw can be driven to rotate by the motor.

[0011] As a further solution of the present utility model, hot pressing blocks are installed on the opposite sides of the two groups of mounting plates. The length of the hot pressing block is less than the length of the mounting plate. The hot pressing block can melt and bond multiple layers of non-woven fabrics together by heating.

[0012] As a further solution of the present utility model, one of the two groups of fixed plates on the left is slidably connected to the top of the top plate, and the group of fixed plates on the right is fixedly connected to the top of the top plate.

[0014] First, the present utility model describes a hot pressing and bonding device for multiple layers of non-woven fabrics. It describes that by installing sliding rails on both sides of the top plate, sliding sleeves are installed on the sliding rails, a U-shaped plate is installed on the tops of the two groups of sliding sleeves, and two groups of hot pressing blocks are installed on the inner side of the U-shaped plate. Such a structure can move the U-shaped plate along the sliding rail to a place close to the cloth winding shaft on the left side of the top plate, facilitating the passing of the first section of multiple layers of non-woven fabrics through the hot pressing block and winding them onto the cloth winding shaft. Subsequently, after starting the hot pressing block, the U-shaped plate can be moved along the sliding rail to the initial position on the right to perform the hot pressing and bonding treatment of multiple layers of non-woven fabrics. Such an operation process enables the operator not to place the hand between the hot pressing blocks and facilitates winding the first section of multiple layers of non-woven fabrics onto the cloth winding shaft, with good safety.

[0015] Second, the present utility model describes a hot pressing and bonding device for multiple layers of non-woven fabrics. It describes that by symmetrically installing limiting blocks at both ends of the sliding rail, the cross-sectional area of the limiting block is larger than the cross-sectional area of the sliding rail, and the internal cross-sectional area of the sliding sleeve is the same as the cross-sectional area of the sliding rail. Thus, the moving range of the sliding sleeve can be restricted by the two groups of limiting blocks, preventing the sliding sleeve from moving along the sliding rail to break away from the sliding rail, and further preventing the U-shaped plate installed on the tops of the two groups of sliding sleeves from detaching from the two sliding rails.

[0027] Preferably, the top area of the bottom plate 3 is larger than the bottom area of the support plate 2, which can provide good stability for the support plate 2. Fixing holes are provided at the four corners of the bottom plate 3, and fixing bolts can be installed therein.

The cross-sectional area of the limiting block 13 is larger than that of the slide rail 4, and the internal cross-sectional area of the sliding sleeve 5 is the same as that of the slide rail 4. Thus, the movement range of the sliding sleeve 5 can be limited by the two groups of limiting blocks 13, so that the sliding sleeve 5 cannot move along the slide rail 4 to disengage from the slide rail 4, and the U-shaped plate 6 installed on the tops of the two groups of sliding sleeves 5 cannot disengage from the two groups of slide rails 4.

[0029] Preferably, chutes are provided on the inner walls on both sides of the inner side of the U-shaped plate 6. Two groups of mounting plates 7 are installed on the inner side of the U-shaped plate 6. Sliders 14 are installed at both ends of the mounting plate 7. The size of the slider 14 is adapted to the size of the chute provided on the inner side of the U-shaped plate 6, and the slider 14 is arranged in the chute. Thus, the mounting plate 7 is installed on the inner side of the U-shaped plate 6, and at the same time, the mounting plate 7 can move vertically along the chutes provided on both sides of the U-shaped plate 6.

[0030] Preferably, two groups of through holes are symmetrically provided on the mounting plate 7, and a set of wire sleeves 9 are installed in each group of through holes. The four wire sleeves 9 on the two mounting plates 7 are in a pairwise corresponding position relationship. Two groups of lead screws 10 are symmetrically installed on the inner side of the U-shaped plate 6. A set of wire sleeves 9 are installed on each group of lead screws 10. The two groups of lead screws 10 are installed on both sides of the two mounting plates 7. The lead screw 10 is of a double-thread structure, and the thread grooves provided on its surface are of a left-right symmetric structure. The bottom of the lead screw 10 is rotatably connected to a rotating plate 15, and the rotating plate 15 is fixedly installed on the inner side of the U-shaped plate 6.

[0031] Preferably, two groups of motors 16 are symmetrically installed on the top of the U-shaped plate 6. Two groups of through holes are symmetrically provided on the top of the U-shaped plate 6. The top of the lead screw 10 passes through the through hole and is connected to the motor 16. Thus, the lead screw 10 can be driven to rotate by the motor 16.

[0032] Preferably, hot pressing blocks 8 are installed on the opposite sides of the two mounting plates 7. The length of the hot pressing block 8 is less than that of the mounting plate 7. The hot pressing block 8 can melt and bond multiple layers of non-woven fabrics together by heating.

[0033] Preferably, one set of fixing plates 12 on the left side among the two sets of fixing plates 12 is slidably connected to the top of the top plate 1, and one set of fixing plates 12 on the right side is fixedly connected to the top of the top plate 1. Rotating shafts 17 are installed on the opposite sides of the two sets of fixing plates 12. Slots adapted to the rotating shafts 17 are formed on the right side of the cloth winding shaft 11. An insertion block 18 is installed on the right side of the rotating shaft 17 installed on the side surface of the left set of fixing plates 12. A slot adapted to the insertion block 18 is formed on the left side of the cloth winding shaft 11. The insertion block 18 is inserted into the interior of the slot. The rotating shaft 17 installed on the left set of fixing plates 12 passes through the left set of fixing plates 12 and forms a rotational connection with this set of fixing plates 12. The left end of this set of rotating shafts 17 extends out of the through hole formed on the fixing plate 12 and is installed with a rocking handle 19. The rocking handle 19 is arranged in a Z-shaped structure. The rocking handle 19 is installed on the left side of the left set of fixing plates 12. Thus, the rotating shaft 17 connected thereto can be rotated through the rocking handle 19. The rotating shaft 17 drives the insertion block 18 installed on its side surface to rotate. The cross section of the insertion block 18 is in a rectangular structure. Such a structure can enable the insertion block 18 to drive the cloth winding shaft 11 to rotate together when rotating.

[0034] Working principle: Before using this device for hot pressing and fusing non-woven fabrics, first move the U-shaped plate 6 along the slide rail 4 to the left side of the top plate 1. At this time, the distance between the U-shaped plate 6 and the cloth winding shaft 11 is very small. Then, one end of multiple layers of non-woven fabrics can be passed through the two groups of hot pressing blocks 8 and wound around the cloth winding shaft 11. Subsequently, start the two groups of motors 16 and ensure that the working states of the two groups of motors 16 are the same, so that the two screw rods 10 rotate synchronously. At this time, since the thread grooves formed on the surface of the screw rod 10 are of a left-right symmetric structure, the two sets of screw sleeves 9 installed on each screw rod 10 will approach each other, thereby driving the two mounting plates 7 to approach each other. At this time, the two groups of hot pressing blocks 8 will approach each other and fix the multiple layers of non-woven fabrics between the two groups of hot pressing blocks 8. Subsequently, power on the two groups of hot pressing blocks 8, and the hot pressing blocks 8 will fuse the multiple layers of non-woven fabrics together by hot pressing and bonding. Then, the U-shaped plate 6 can be pushed to move to the right. At this time, all the multiple layers of non-woven fabrics between the cloth winding shaft 11 and the U-shaped plate 6 on the top of the top plate 1 have undergone the hot pressing and bonding treatment by the hot pressing blocks 8. Then, the cloth winding shaft 11 can be rotated by turning the crank 19 to wind the multiple layers of non-woven fabrics that have completed the hot pressing and bonding treatment onto the cloth winding shaft 11. During this process, the two groups of hot pressing blocks 8 continuously perform hot pressing and bonding treatment on the newly provided multiple layers of non-woven fabrics. The speed of this process can be controlled by the speed of turning the crank 19. After the multiple layers of non-woven fabrics on the cloth winding shaft 11 are wound to a certain length, the multiple layers of non-woven fabrics can be cut. Then, one set of fixed plates 12 on the left can be slid to separate from the top plate 1. At this time, the insertion block 18 disengages from the slot formed on the left side of the cloth winding shaft 11. Then, the cloth winding shaft 11 can be removed from the top of the top plate 1 so as to remove the multiple layers of non-woven fabrics wound on the cloth winding shaft 11. Then, install one set of fixed plates 12 on the left back to the top of the top plate 1. At this time, the cloth winding shaft 11 is also reinstalled between the two sets of fixed plates 12, and the hot pressing and bonding and winding operations of the multiple layers of non-woven fabrics can be continued.
