Description

Technical Field

[0001] The utility model relates to the technical field of melt - blown non - woven fabric production, and particularly relates to a fixing structure for a melt - blown die head used in melt - blown non - woven fabric production. Background Technique

[0002] As is well known, melt - blown cloth is the "heart" of masks. Therefore, the melt - blown cloth die is the die used to produce melt - blown cloth, which is also called a melt - blown cloth nozzle or spinneret plate in the industry. The melt - blown cloth die is made of steel such as YK30 (SK3) carbon tool steel. For the die head of melt - blown cloth, the pore diameter of the spinning micropores is extremely small, and laser drilling is used with relatively high precision.

[0003] In the prior art, a melt - blown die head sliding mechanism for melt - blown cloth production with the publication number of CN213037956U includes an installation frame, a melt - blown die head, and a sliding device. The melt - blown die head is arranged at the bottom of the installation frame, and the melt - blown die head is slidably connected to the installation frame through the sliding device. By adding the sliding device, under the premise that an external air compressor is manually turned on to drive the cylinder to operate, the melt - blown die head can slide at the bottom of the installation frame driven by the telescopic rod of the cylinder, so that the melt - blown die head can be in a relative motion state with the conveyor belt. Thus, the non - woven fabric blown by the melt - blown die head can be in a double - layer structure or a multi - layer structure, greatly reducing the gaps formed on the non - woven fabric, and effectively ensuring the processing quality and later use efficiency of the non - woven fabric.

[0004] However, in the above - mentioned structure, during the sliding process of the melt - blown die head, due to the certain weight of the melt - blown die head, there will be some deviation during sliding, resulting in the melt - blown die head slipping and misaligning. Content of the Utility Model

[0005] The purpose of the utility model is to provide a fixing structure for a melt - blown die head used in melt - blown non - woven fabric production. By using this device for work, the problem that during the sliding process of the melt - blown die head, due to the certain weight of the melt - blown die head, there will be some deviation during sliding, resulting in the melt - blown die head slipping and misaligning can be solved.

[0006] To achieve the above - mentioned purpose, the utility model provides the following technical solution: A fixing structure for a melt - blown die head used in melt - blown non - woven fabric production includes a base. A support plate is arranged at the upper end of the base. A moving component for moving the melt - blown die head is arranged on one side of the support plate, and a fixing component for fixing the melt - blown die head is arranged on one side of the moving component.

[0007] The fixed component includes telescopic rods arranged on both sides of the moving component. A clamping plate is arranged on one side of the telescopic rod. One side of the fixed component is provided with a fixing plate. There are two groups of the fixing plates. Rubber pads are arranged on the relative inner sides of the two groups of fixing plates. One side of the fixing plate is provided with a connecting rod. There are two groups of the connecting rods. One group of the connecting rods is fixedly connected to one group of the fixing plates. A fixed shaft is rotatably connected to one side of the two groups of connecting rods. A spring is arranged between the two groups of connecting rods.

[0008] Further, the moving component includes a slide rail arranged on one side of the support plate. A telescopic cylinder is arranged on the inner wall of the slide rail. A slider is slidably connected inside the slide rail. The telescopic end of the telescopic cylinder is fixedly connected to the slider.

[0009] Further, a moving groove is opened on one side of the slide rail. A connecting plate is arranged on one side of the slider. The connecting plate moves in the moving groove.

[0010] Further, there are two groups of the connecting plates. A fixing rod is arranged between the two groups of connecting plates. The connecting plate is fixedly connected to the telescopic rod.

[0011] Further, the clamping plate is snap-connected to a meltblown box. A meltblown die head is arranged at the lower end of the meltblown box. Clamping grooves are opened on the outer surface of the meltblown die head and the meltblown box.

[0012] Further, clamping blocks are arranged on the relative inner sides of the two groups of clamping plates. The clamping blocks are snap-connected to the clamping grooves.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] The present utility model provides a fixing structure for a meltblown die head used in the production of meltblown non-woven fabrics. Through the settings of the base, fixed component, telescopic rod, connecting rod, fixed shaft, clamping groove, spring, clamping plate, fixing plate and rubber pad, the meltblown die head is placed between the two groups of clamping plates. The telescopic rod extends to adjust the clamping distance according to the size of the meltblown die head, squeezing one group of connecting rods, so that the spring is squeezed. Thus, the two groups of rubber pads contact the surface of the meltblown die head to be able to clamp and fix it firmly, reducing the probability of loosening and falling off during the movement of the meltblown die head.
