Description

Technical Field

[0001] This utility model relates to the field of spunbond spinneret technology, and in particular to a novel spunbond spinneret with 3C spinneret holes. Background Technology

[0002] The spunbond spinneret is the core component in the production of spunbond nonwoven fabrics. It is responsible for extruding the polymer melt into a fine stream, which is then cooled, stretched, and formed into continuous filaments and laid into a web to form a fabric.

[0003] Traditional spunbond spinnerets rely solely on external packaging for secure transport, making them susceptible to damage due to displacement. Current solutions involve installing permanent supports on both sides of the spinneret for ease of transport; however, this occupies production line space. Therefore, there is a pressing need for a spunbond spinneret with adjustable supports. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel spunbond spinneret with 3C spinneret holes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel spunbond spinneret with 3C spinneret holes includes a spunbond spinneret body, on which multiple spinneret holes are formed. Multiple receiving cavities are formed on both sides of the spunbond spinneret body, and movable plates are movably arranged in each receiving cavity. Each movable plate has a first through hole and a second through hole. A retaining post is vertically movably arranged on the spunbond spinneret body above the movable plate by means of a spring, and the first through hole and the second through hole are adapted to the retaining post.

[0007] In addition, a preferred structure is that guide members are fixedly provided on both sides of the movable plate, and guide grooves adapted to the guide members are provided on the inner wall of the storage cavity.

[0008] In addition, a preferred structure is that each of the spunbond spinneret bodies has a spring cavity above the receiving cavity, and a spring is provided downward at the top of each spring cavity.

[0009] In addition, in a preferred configuration, the other end of each spring is connected to a locking post, and each locking post is provided with a pull plate.

[0010] Furthermore, in a preferred configuration, an adjustment cavity is provided outward on one side of the spring cavity within the spunbond spinneret body, and all pull plates are adapted to move vertically within the adjustment cavity.

[0011] Furthermore, a preferred structure is that the spinnerets are arranged alternately in sequence, and each spinneret consists of three arc-shaped cavities.

[0012] The beneficial effects of this utility model are as follows: spunbond nonwoven fabrics can be produced through the spunbond spinneret body. By fixing the locking post in the first or second through hole, the movable plate can be fixed in different positions. During transportation, the movable plate can be pulled out to fix the spunbond spinneret body with screws. After transportation, the movable plate can be pushed into the storage cavity to avoid occupying production line layout space. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-7A novel spunbond spinneret with 3C spinneret holes includes a spunbond spinneret body 1, on which multiple spinneret holes 2 are formed. Multiple receiving cavities 11 are formed on both sides of the spunbond spinneret body 1, and movable plates 3 are movably disposed within each receiving cavity 11. Each movable plate 3 has a first through hole 31 and a second through hole 32. A retaining post 4 is vertically movably disposed on the spunbond spinneret body 1 above the movable plate 3 via a spring 5, and both the first through hole 31 and the second through hole 32 are adapted to the retaining post 4.

[0023] Guide members 33 are fixedly installed on both sides of the movable plate 3, and guide grooves 12 adapted to the guide members 33 are opened on the inner wall of the receiving cavity 11. The adaptation between the guide members 33 and the guide grooves 12 can not only improve the stability of the movable plate 3 during movement, but also prevent the movable plate 3 from falling off.

[0024] The spunbond spinneret body 1 has a spring cavity 13 located above the receiving cavity 11, and a spring 5 is positioned downwards at the top of each spring cavity 13. Through the elastic force of the spring 5, combined with the gravity of the locking post 4, the locking post 4 can be stably locked into the first through hole 31 or the second through hole 32. It is worth noting that the spring 5 is a high-strength anti-vibration spring in the prior art, ensuring sufficient preload even under extreme vibration conditions. This is prior art and will not be elaborated further.

[0025] The other end of each spring 5 is connected to a locking post 4, and each locking post 4 is equipped with a pull plate 41. An adjustment cavity 14 is provided outwardly on one side of the spring cavity 13 within the spunbond spinneret body 1, and each pull plate 41 is adapted to move vertically within the adjustment cavity 14. The pull plates 41 facilitate user adjustment of the position of the locking posts 4.

[0026] The spinnerets 2 are arranged alternately, and each spinneret 2 consists of three arc-shaped cavities. The arrangement of the 3C spinnerets in this application allows the material to have a larger volume and greater fluffiness after spinning.

[0027] In this embodiment, spunbond nonwoven fabric can be produced by the spunbond spinneret body 1. This is prior art and is not a major technical problem to be solved in this technical solution. Therefore, it will not be described in detail in this application.

[0028] Furthermore, when the spunbond spinneret body 1 needs to be transported, simply pull the pull plate 41 upwards. At this time, the locking post 4 moves upwards and releases the mutual opening between itself and the second through hole 32. The spring 5 is compressed, and the first through hole 31 and the locking post 4 are adapted and aligned.

[0029] The user can then directly pull out the movable plate 3, causing the second through hole 32 to move to the outside of the storage cavity 11. Next, simply release the pull plate 41, and the locking post 4 will automatically move downwards and reset under its own weight and the elastic force of the spring 5, at which point the locking post 4 will automatically engage with the first through hole 31. This secures the movable plate 3. The user then simply passes the screw through the second through hole 32 and screws it onto the positioning component on the transport mechanism. After performing this operation on all movable plates 3, the spunbond spinneret body 1 can be transported and secured.

[0030] Furthermore, after the spunbond spinneret body 1 has been transported, simply remove all the screws and then pull the pull plate 41 upwards again to release the mutual locking between the locking post 4 and the first through hole 31. At this time, the movable plate 3 can be pushed into the storage cavity 11, and the second through hole 32 will once again be aligned with the locking post 4. Then, simply release the pull plate 41, and the locking post 4 will automatically move downwards and reset itself by its own weight and the elastic force of the spring 5. At this time, the locking post 4 will automatically lock into the second through hole 32 to realize the storage of the movable plate 3.

[0031] In this invention, spunbond nonwoven fabric can be produced by the spunbond spinneret body 1. By locking the pin 4 in the first through hole 31 or the second through hole 32, the movable plate 3 can be fixed in different positions. During transportation, the movable plate 3 can be pulled out and fixed to the spunbond spinneret body 1 with screws. After transportation, the movable plate 3 can be pushed into the storage cavity 11 to avoid the movable plate 3 occupying the production line layout space.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
