Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, and more specifically, to a cutting device for nonwoven fabric production. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, needle-punched cotton, needle-punched non-woven fabric, etc., is a type of fabric formed without spinning or weaving. During production, cutting non-woven fabric into sheets facilitates subsequent processing and handling. Cut non-woven fabric is easier to process, such as sewing, heat sealing, and printing. The cut material is also more flexible and easier to handle.

[0003] In the process of nonwoven fabric production, a cutting device is required. For example, a fully automatic nonwoven fabric slicing machine disclosed in the existing patent publication number CN216074484U includes a rolling device and a cutting device. Since the motor is electrically connected to both the rolling device and the cutting device, the motor provides power to the rolling device and the cutting device. After starting the motor, the second switch is turned on. The user can set the size of the fabric according to the actual needs through the controller, place the fabric at one end of the rolling belt, turn on the first switch to start the rolling device, and when the fabric moves to the bottom of the cutting device, the blade automatically cuts it.

[0004] When the above-mentioned device cuts the non-woven fabric, since the non-woven fabric is not positioned, the non-woven fabric is prone to incomplete cutting during the cutting process. Furthermore, direct cutting on the rolling belt will have a certain impact on the rolling belt. Utility Model Content

[0036] To further understand the utility model's content, features, and effects, the following embodiments are provided, along with detailed descriptions in conjunction with the accompanying drawings:

[0037] Reference Figure 1 and Figure 2 The nonwoven fabric production cutting device in this embodiment includes a positioning frame 11 and a lower pressure plate 12 slidably connected in the positioning frame 11. A cutting blade 13 is fixedly connected to the bottom of the lower pressure plate 12.

[0038] The positioning assembly 14 includes several sets of support rods 141 and fixing plates 142. The top of the support rods 141 is fixedly connected to the bottom of the lower pressure plate 12, and the fixing plates 142 are fixedly connected to the end of the support rods 141 away from the lower pressure plate 12.

[0039] The collection trough 15 is slidably connected within the positioning frame 11;

[0040] Sliding components 16 are installed on both sides of the collection tank 15 and are used to move the collection tank 15 up and down.

[0041] The buffer assembly 17 is installed at the bottom of the lower pressure plate 12 and close to the side of the cutting blade 13. It is used to buffer the downward cutting of the cutting blade 13 and to position the non-woven fabric at the same time.

[0042] as well as

[0043] The support plate 18 is fixedly connected to both sides of the inner wall of the positioning frame 11 and is located below the cutting blade 13.

[0044] Reference Figure 3 The sliding assembly 16 includes two sets of sliders 161 and sliding grooves 162. The two sets of sliders 161 are fixedly connected to both sides of the collecting groove 15, and the two sets of sliding grooves 162 are respectively opened on both sides of the inner wall of the positioning frame 11. The sliders 161 slide in the sliding grooves 162. A sliding rod 163 is fixedly connected in the sliding groove 162. The sliders 161 have sliding holes for sliding with the sliding rod 163. A first spring 164 is sleeved on the sliding rod 163. One end of the first spring 164 is fixedly connected to the bottom of the slider 161. The first spring 164 is away from the slider 161. One end is fixedly connected to the bottom of the inner wall of the slider 161. The collection groove 15 is pressured by the fixing plate 142, which drives the slider 161 to slide downward on the slide rod 163, squeezing the first spring 164. The cutting blade 13 cuts the non-woven fabric. The cut non-woven fabric is placed in the collection groove 15. The elastic force of the first spring 164 pops the collection groove 15 upward. The top of the collection groove 15 contacts the bottom of the support plate 18, which can work with the fixing plate 142 to fix the other end of the non-woven fabric, and at the same time facilitate the collection groove 15 to collect the non-woven fabric.

[0045] Reference Figure 4 The buffer assembly 17 includes several sets of first limiting rods 171 and second limiting rods 172. The top of the first limiting rod 171 is fixedly connected to the bottom of the lower pressure plate 12. The second limiting rod 172 is slidably connected inside the first limiting rod 171. The end of the second limiting rod 172 away from the first limiting rod 171 is fixedly connected to the top of the limiting plate 173. A second spring 174 is sleeved on the second limiting rod 172. The top of the second spring 174 is fixedly connected to the bottom of the first limiting rod 171. The end of the second spring 174 away from the first limiting rod 171 is fixedly connected to the top of the limiting plate 173. The lower pressure plate 12 moves downward, and the limiting plate 173 contacts the surface of the nonwoven fabric. As the lower pressure plate 12 drives the cutting blade 13 to continue pressing down, the second limiting rod 172 slides upward inside the first limiting rod 171. The limiting plate 173 is compressed by the limiting plate 173 and contracts, which can fix one end of the nonwoven fabric and reduce the phenomenon of incomplete cutting of the nonwoven fabric.

[0046] Reference Figure 4The top of the support plate 18 is provided with a cutting groove 19, which is located below the cutting blade 13. By setting the cutting groove 19 and the support plate 18, the cutting blade 13 can cut the non-woven fabric more completely.

[0047] Reference Figure 3 Two sets of electric hydraulic rods 20 are fixedly connected to the top of the lower pressure plate 12. The electric hydraulic rods 20 are installed on the positioning frame 11. By setting the electric hydraulic rods 20, the lower pressure plate 12 can be driven to move downward, so that the cutting blades 13 can cut the non-woven fabric.

[0048] Reference Figure 2 Guide blocks 21 are fixedly connected to both ends of the lower pressure plate 12. Guide grooves 22 for sliding in cooperation with the guide blocks 21 are respectively opened at both ends of the inner wall of the positioning frame 11. By setting the guide blocks 21, the lower pressure plate 12 can slide up and down more accurately, and the movement of the lower pressure plate 12 is guided.

[0049] Reference Figure 1 The positioning frame 11 is equipped with a conveying mechanism 23. The discharge end of the conveying mechanism 23 is on one side of the feed end of the support plate 18, and the conveying mechanism 23 and the support plate 18 are on the same horizontal line. By setting the conveying mechanism 23, the non-woven fabric can be conveyed to complete continuous feeding and improve cutting efficiency.

[0050] Reference Figure 1 The top of the positioning frame 11 is fixedly connected to two sets of positioning blocks 24, and a set of positioning rollers 25 is rotatably connected between the two sets of positioning blocks 24. By setting the positioning rollers 25, they can cooperate with the conveying mechanism 23 to convey the non-woven fabric and reduce the displacement of the non-woven fabric.

[0051] Reference Figure 4 The top of the collection trough 15 contacts the bottom of the support plate 18, which can limit and fix one end of the non-woven fabric.

[0052] Reference Figure 4 Both the limiting plate 173 and the fixing plate 142 are equipped with rubber pads at their bottoms. By setting the rubber pads, the scratches caused by the bottoms of the limiting plate 173 and the fixing plate 142 on the non-woven fabric surface can be reduced.

[0053] In summary: When cutting nonwoven fabric, the nonwoven fabric to be cut is first placed on the conveying mechanism 23. The conveying mechanism 23 starts working, conveying the nonwoven fabric to the support plate 18 and extending to the collection trough 15. The electric hydraulic rod 20 starts working, driving the lower pressure plate 12 to move downward. The lower pressure plate 12 drives the guide block 21 to slide downward in the guide groove 22. As the lower pressure plate 12 moves downward, the limiting plate 173 contacts the surface of the nonwoven fabric. At the same time, the fixing plate 142 moves downward. As the lower pressure plate 12 drives the cutting blade 13 to continue pressing down, the second limiting rod 172 slides upward within the first limiting rod 171. The limiting plate 173 contracts under the pressure of the limiting plate 173, and the fixing plate 142 presses the non-woven fabric on the collection trough 15 downward. The collection trough 15 is pressured by the fixing plate 142, which drives the slider 161 to slide downward on the slide rod 163, compressing the first spring 164. The cutting blade 13 cuts the non-woven fabric, and the cut non-woven fabric is placed in the collection trough 15. The elastic force of the first spring 164 pops the collection trough 15 upward. The top of the collection trough 15 contacts the bottom of the support plate 18, which can limit and fix one end of the non-woven fabric, reduce the situation of incomplete cutting of the non-woven fabric, and reduce damage to the conveying mechanism 23.
