Abstract
Description
Technical Field
[0001] This utility model relates to the field of opening machine technology, and more specifically, to a uniform opening device for nonwoven fabrics. Background Technology
[0002] Non-woven fabric, also known as non-woven cloth, is composed of oriented or randomly arranged fibers. It is a new generation of environmentally friendly material with advantages such as high strength, breathability, waterproofing, environmental friendliness, flexibility, non-toxicity, odorlessness, and low price. It is a new generation of environmentally friendly material with characteristics such as water repellency, breathability, flexibility, non-combustibility, non-toxicity, non-irritation, and rich colors. It is often produced using polypropylene (PP) granules as raw material, through a continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing. The function of the opening machine is to loosen the compressed and entangled fiber raw materials. The degree of loosening of the non-woven fiber raw materials has a significant impact on the quality of semi-finished products and finished non-woven fabrics, as well as material savings.
[0003] According to Chinese Patent CN202321574760.4, an opening machine for nonwoven fabric processing is described. This application utilizes a drive motor housed within a protective casing to rotate a driving gear that meshes with a connecting gear. When the connecting gear rotates, it meshes with a driven gear, causing the opening angle nail roller to rotate in the opposite direction. This results in synchronous rotation of the auxiliary angle nail roller and the opening angle nail roller, eliminating the need for two separate motors to drive the auxiliary and opening angle nail rollers, thus reducing production costs. Existing opening machines often mix dust and impurities with the nonwoven fabric during the opening process, requiring separate sieving of the nonwoven fabric after opening, which is time-consuming.

The bottom end of the box body 1 is provided with a plurality of evenly distributed support blocks 2. The top side of the box body 1 is provided with a feeding hopper 3. The top end of the box body 1 is provided with a drying box 4 connected thereto. The side of the box body 1 is provided with a discharge port 5. The box body 1 is provided with symmetrically arranged rotating shafts 6 located directly below the feeding hopper 3.

[0026] Example 2;
[0027] like Figure 1-4As shown, the device includes a housing 1, with several evenly distributed support blocks 2 at the bottom. A hopper 3 is located on one side of the top of the housing 1, and a drying chamber 4 connected to it is located at the top of the housing 1. A discharge port 5 is opened on one side of the housing 1. Symmetrically arranged rotating shafts 6 are located in the housing 1 directly below the hopper 3. Opening angle nail rollers 7 are fixedly fitted onto the outer walls of both sets of rotating shafts 6. One side of each set of rotating shafts 6 extends outside the housing 1 and connects to a linkage assembly. A screening assembly is located in the housing 1 at the bottom of the opening angle nail rollers 7. Several evenly distributed fans 8 are located in the drying chamber 4, connected to the housing 1 via a connecting frame 9. A heating wire 10 is located in the drying chamber 4 at the bottom of the fans 8, and a dustproof net 11 is located at the top of the drying chamber 4. The linkage assembly includes a mounting base 12 on one side of the housing 1, a motor 13 on one side of the mounting base 12, a double-groove pulley 14 on the drive end of the motor 13, and two sets of rotating shafts 6 extending to the outside of the housing 1 and connected to driven pulleys 15 respectively. Both sets of driven pulleys 15 are connected to the double-groove pulleys 14 via a transmission belt 16. When opening the nonwoven fabric, the nonwoven fabric is placed in the housing 1 through the hopper 3. During this process, the motor 13 is started to drive the double-groove pulleys 14 to rotate. The double-groove pulleys 14 drive the two sets of driven pulleys 15 to rotate synchronously via the transmission belt 16. The two sets of driven pulleys 15 drive the two sets of rotating shafts 6 to rotate, and the two sets of rotating shafts 6 drive the two sets of opening angle nail rollers 7 to rotate, thus opening the nonwoven fabric. By setting up the linkage assembly, the two sets of opening angle nail rollers can be driven to rotate synchronously to open the nonwoven fabric, improving its synchronization.
[0028] Example 3;
[0029] like Figure 1-4As shown, the device includes a box body 1, with several evenly distributed support blocks 2 at the bottom of the box body 1, a feeding hopper 3 on one side of the top of the box body 1, a drying box 4 connected to the top of the box body 1, a discharge port 5 on one side of the box body 1, symmetrically arranged rotating shafts 6 located in the box body 1 and directly below the feeding hopper 3, with opening angle nail rollers 7 fixedly fitted on the outer walls of both sets of rotating shafts 6, and one side of both sets of rotating shafts 6 extending to the outside of the box body 1 and connected to the linkage assembly, and a screening assembly located in the box body 1 and at the bottom of the opening angle nail rollers 7. The screening assembly includes an inclined screening plate 17 located at the bottom end of the opening angle nail roller 7 within the housing 1. One side of the screening plate 17 is connected to the housing 1 via a second rotating shaft 18, and the side of the screening plate 17 away from the second rotating shaft 18 is connected to the housing 1 via a spring 19. A third rotating shaft 20 is located at the top of the screening plate 17 within the housing 1, and the outer wall of the third rotating shaft 20 is provided with several evenly distributed striking rods 21. A dust collection pipe 22 is located at the bottom end of the housing 1, and a matching pipe cap is provided at the bottom end of the dust collection pipe 22. One side of the third rotating shaft 20 extends outside the housing 1 and is connected to the drive end of a second motor 23. A roller 24 is provided on one side of the striking rod 21. When the non-woven fabric is opened and falls onto the screening plate 17, the second motor 23 is started, driving the third shaft 20 to rotate. The third shaft 20 drives the striking rod 21 to rotate, and the striking rod 21 drives the roller 24 to intermittently strike the screening plate 17, causing the screening plate 17 to intermittently compress the spring 19 to achieve a vibration effect. This causes the non-woven fabric to slide quickly from the screening plate 17 to the discharge port 5 for discharge. At the same time, the vibration of the screening plate 17 accelerates the filtration of dust and impurities. Meanwhile, the fan 8 is started, blowing the gas heated by the heating wire 10 into the box 1 to dry the non-woven fabric. By setting up the screening component, the non-woven fabric after opening can be screened and filtered to remove dust from the non-woven fabric. There is no need to transfer and screen the non-woven fabric again, which improves its processing efficiency.
[0030] In practical applications, when opening nonwoven fabric, the nonwoven fabric is placed into the box 1 through the feed hopper 3. During this process, the motor 13 is started to drive the double-groove pulley 14 to rotate. The double-groove pulley 14 drives two sets of driven pulleys 15 to rotate synchronously through the transmission belt 16. The two sets of driven pulleys 15 drive two sets of rotating shafts 6 to rotate, and the two sets of opening angle nail rollers 7 to rotate to open the nonwoven fabric. By setting up a linkage component, the two sets of opening angle nail rollers can be driven to rotate synchronously to open the nonwoven fabric, improving its synchronization. When the nonwoven fabric is opened and falls onto the screening plate 17, the motor 2 is started. 23 drives the rotating shaft 20 to rotate, which in turn drives the striking rod 21 to rotate. The striking rod 21 drives the roller 24 to intermittently strike the screening plate 17, causing the screening plate 17 to intermittently compress the spring 19 to achieve a vibration effect. This causes the non-woven fabric to slide quickly from the screening plate 17 to the discharge port 5 for discharge. At the same time, the vibration of the screening plate 17 accelerates the filtration of dust and impurities. Meanwhile, the fan 8 starts and blows the gas heated by the heating wire 10 into the box 1 to dry the non-woven fabric. By setting up the screening component, the non-woven fabric after opening can be screened and filtered to remove dust from the non-woven fabric. This eliminates the need to transfer and screen the non-woven fabric again, thus improving its processing efficiency.
[0031] In summary, by means of the above-mentioned technical solution of this utility model, by setting up a linkage component, two sets of opening angle nail rollers can be driven to rotate synchronously to open the non-woven fabric, thereby improving its synchronization. By setting up a screening component, the non-woven fabric after opening can be screened and filtered to remove dust from the non-woven fabric without having to transfer and screen the non-woven fabric again, thereby improving its processing efficiency.
