Description

Technical Field

[0001] This utility model belongs to the field of cotton soft towel production technology, and specifically relates to a raw material crushing device for cotton soft towel production. Background Technology

[0002] Cotton wipes are environmentally friendly dry wipes made from natural fibers such as cotton and viscose using a spunlace nonwoven process. The production process employs high-pressure steam sterilization, meeting medical-grade hygiene standards. They are soft, skin-friendly, and highly absorbent, and can replace traditional paper towels and synthetic fiber wiping products.

[0003] In the production and processing of cotton soft towels, raw material crushing is a crucial preliminary step. Its crushing effect directly affects the texture, feel, and production quality of the subsequent cotton soft towels. However, existing cotton soft towel raw material crushing devices usually rely on only a set of crushing blades with a fixed rotation speed to cut and crush the raw materials. The single crushing structure is difficult to crush the raw materials in an all-round and multi-layer manner, resulting in low crushing efficiency and uneven crushing effect. Ultimately, this leads to uneven texture of the produced cotton soft towels and reduces the performance of the finished cotton soft towels.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] The rotating assembly includes a rotating rod, which is coaxially and rotatably installed in the inner cavity of the crushing cylinder. A driven gear is installed at one end of the rotating rod, and multiple positioning grooves are provided on the rotating rod. The crushing assembly is slidably installed in the positioning grooves.

[0007] The crushing component includes a positioning sleeve, which is fitted onto a rotating rod. The inner wall of the positioning sleeve is provided with positioning plates, the same number as the number of positioning slots. One positioning plate is slidably disposed in one positioning slot. A return spring is provided in the positioning slot. One end of the return spring contacts the inner wall of the positioning slot, and the other end contacts one side of the positioning plate. Multiple crushing components are evenly installed on the outer circumference of the positioning sleeve.

[0008] The drive assembly includes a mounting bracket mounted on one side of the processing chamber. A drive device is mounted on the mounting bracket, and a first drive gear and a second drive gear are coaxially mounted on the drive end of the drive device. The first drive gear meshes with a driven gear. The drive assembly also includes a mounting base coaxially mounted on one side of the crushing cylinder. A driven gear ring is coaxially mounted on the mounting base, and the driven gear ring meshes with the second drive gear. The transmission ratio between the first drive gear and the driven gear is less than the transmission ratio between the second drive gear and the driven gear ring.

[0009] The linkage structure includes a positioning rod, one end of which is mounted on one side of the processing box. The positioning rod and the rotating rod are coaxially arranged, and one end of the rotating rod is coaxially rotatably mounted on the positioning rod.

[0012] The processing box has a bottom plate inside, which is located below the crushing cylinder and is inclined. A closable material handling door is installed on one side of the processing box, located at the lower end of the bottom plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model uses the periodic contact and separation of the first and second inclined blocks to cause the crushing component to periodically reciprocate under the action of the return spring. The driving device simultaneously drives the crushing component and the crushing cylinder to rotate, while the rotation speed of the crushing cylinder is less than that of the crushing component.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-9 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0028] Please see Figures 1-5 As shown:

[0029] This embodiment provides a raw material crushing device for cotton towel production, including a processing box 1. A crushing cylinder 2 is horizontally installed inside the processing box 1. Several through holes are evenly opened on the outer circumference of the crushing cylinder 2. A rotating component 3 is installed inside the crushing cylinder 2. A crushing component 4 is coaxially installed on the rotating component 3. A driving component 5 is installed on one side of the processing box 1. The driving component 5 can drive the rotating component 3 and the crushing cylinder 2 to rotate simultaneously. The crushing component 4 will rotate synchronously with the rotating component 3. A linkage structure 6 is provided at one end of the crushing component 4. The linkage structure 6 is used to drive the crushing component 4 to move in a staggered manner while rotating.

[0030] The raw cotton tissue is placed inside the crushing cylinder 2. Then, the drive assembly 5 is activated, which drives the rotating assembly 3 and the crushing assembly 4 to rotate at high speed. The crushing assembly 4 cuts and crushes the raw cotton tissue inside the crushing cylinder 2. The drive assembly 5 also drives the crushing cylinder 2 to rotate, causing the raw cotton tissue inside to move dynamically. This continuously moves the raw material to the working area of ​​the crushing assembly 4, preventing the raw material from accumulating in certain areas. At the same time, when the crushing assembly 4 rotates, the linkage structure 6 applies a lateral force to the crushing assembly 4, causing it to slide back and forth along its own axis while rotating. This changes the position of the crushing assembly 4, thereby expanding the coverage area of ​​the working area of ​​the crushing assembly 4. This eliminates the crushing blind spots caused by the fixed trajectory in traditional devices and improves the uniformity and efficiency of crushing the raw cotton tissue.

[0031] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8As shown, the rotating assembly 3 includes a rotating rod 7, which is coaxially rotatably installed in the inner cavity of the crushing cylinder 2. A driven gear 8 is installed at one end of the rotating rod 7, and multiple positioning slots 9 are provided on the rotating rod 7. The crushing assembly 4 includes a positioning sleeve 10, which is fitted onto the rotating rod 7. The inner wall of the positioning sleeve 10 is provided with positioning plates 11, the same number as the positioning slots 9. One positioning plate 11 is slidably disposed in one positioning slot 9. A return spring 12 is provided in the positioning slot 9, with one end of the return spring 12 contacting the inner wall of the positioning slot 9 and the other end contacting one side of the positioning plate 11. Multiple crushing parts 13 are evenly installed on the outer circumference of the positioning sleeve 10. Through the cooperation of the driven gear 8 and the drive assembly 5, the rotating rod 7 is driven to rotate, so that the positioning sleeve 10... The synchronous rotation drives the crushing component 13 to rotate, crushing the cotton towel material inside the crushing cylinder 2. When the positioning sleeve 10 is continuously rotating and is subjected to the force of the linkage structure 6, the positioning plate 11 will slide in the positioning groove 9 through the force, compressing the return spring 12. At this time, the crushing component 13 moves with the positioning sleeve 10 to change the contact position with the material. When the force of the linkage structure 6 disappears, the return spring 12 will release the compression potential energy, thereby pushing the positioning plate 11 to slide in the positioning groove 9 to the initial position, driving the positioning sleeve 10 and the crushing component 13 back to the initial position. This achieves the effect of the crushing component 13 rotating and periodically reciprocating to cover all the space inside the crushing cylinder 2, improving the crushing efficiency and effect.

[0032] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7As shown, the drive assembly 5 includes a mounting bracket 14, which is mounted on one side of the processing box 1. A drive device 15 is mounted on the mounting bracket 14. The drive device 15 includes, but is not limited to, a motor. A first drive gear 16 and a second drive gear 17 are coaxially mounted on the drive end of the drive device 15. The first drive gear 16 meshes with a driven gear 8. The drive assembly 5 also includes a mounting base 19, which is coaxially mounted on one side of the crushing cylinder 2. A driven gear ring 20 is coaxially mounted on the mounting base 19. The driven gear ring 20 meshes with the second drive gear 17. The transmission ratio between the first drive gear 16 and the driven gear 8 is less than that between the second drive gear 16 and the driven gear 8. The transmission ratio between gear 17 and driven gear ring 20 is determined by starting drive device 15, which drives first drive gear 16 and second drive gear 17 to rotate. This, in turn, drives driven rod 7 to rotate via driven gear 8, causing crushing component 13 to rotate. Driven mounting base 19 rotates via driven gear ring 20, causing crushing cylinder 2 to rotate. The transmission ratio between crushing cylinder 2 and crushing component 13 is different, resulting in crushing cylinder 2 rotating at a lower speed than crushing component 13. This design allows the cotton tissue material inside crushing cylinder 2 to be evenly tumbled, avoiding local accumulation and ensuring more even contact between the cotton tissue material and crushing component 13, thus improving crushing effect and efficiency.

[0033] like Figure 2 , Figure 4 , Figure 8 , Figure 9 As shown, the linkage structure 6 includes a positioning rod 21. One end of the positioning rod 21 is mounted on one side of the processing box 1. The positioning rod 21 is coaxially arranged with the rotating rod 7, and one end of the rotating rod 7 is coaxially rotatably mounted on the positioning rod 21. A first linkage plate 22 is coaxially mounted on one end of the positioning rod 21. A plurality of first inclined blocks 23 are evenly installed on one side of the first linkage plate 22. The linkage structure 6 also includes a second linkage plate 24. The second linkage plate 24 is coaxially mounted on one end of the positioning sleeve 10. A plurality of second inclined blocks 25 are evenly installed on one side of the second linkage plate 24. The number of second inclined blocks 25 is the same as that of the first inclined blocks 23, and they can all be matched. When the rotating rod 7 drives the positioning sleeve 10 to rotate, the second linkage plate 24 moves with the positioning sleeve 10. The second inclined block 25 rotates synchronously and continuously drives the second inclined plate 24 to make circular motion. As the second connecting plate 24 continues to rotate, the second inclined block 25 will periodically contact and separate from the first inclined block 23. When the rotating second inclined block 25 contacts the inclined surface of the stationary first inclined block 23, it will generate forced compression, thereby driving the second connecting plate 24 and the positioning sleeve 10 to slide laterally, causing the return spring 12 to be compressed. When the second inclined block 25 is not in contact with the first inclined block 23, the return spring 12 will drive the positioning plate 11 to slide in the positioning groove 9, so as to drive the positioning sleeve 10 back to the initial position. This allows the crushing part 13 to move laterally while rotating, increasing the crushing area and improving the crushing effect and efficiency.

[0034] like Figure 3 , Figure 6 As shown, a blower box 26 is installed inside the processing box 1. Multiple air outlet nozzles 27 are evenly installed on the blower box 26. The air outlet of the air outlet nozzle 27 is directly facing the surface of the crushing cylinder 2, so that the external air supply pipe can be connected to the blower box 26 to continuously deliver high-pressure airflow into the interior. The high-pressure airflow is applied to the outer surface of the crushing cylinder 2 through the air outlet nozzles 27, thereby preventing the through hole of the crushing cylinder 2 from being blocked by the cotton soft tissue material and ensuring the feeding speed of the crushed cotton soft tissue material.

[0035] like Figure 3 , Figure 5 As shown, a door is provided at one end of the crushing cylinder 2, and an openable feed door 28 is provided inside the door. The operator can open the feed door 28 to put the cotton soft tissue raw material into the crushing cylinder 2, and crush it by the crushing component 13. At the same time, the feed door 28 is closed during the crushing operation to ensure the sealing of the crushing cylinder 2 and prevent the cotton soft tissue raw material from scattering to the outside.

[0036] like Figure 2 , Figure 3 , Figure 6 As shown, the processing box 1 has a bottom plate 29 inside, which is located below the crushing cylinder 2 and is inclined. A closable material retrieval door 30 is installed on one side of the processing box 1. The material retrieval door 30 is located at the lower horizontal end of the bottom plate 29. The crushed cotton soft towel raw material will fall onto the bottom plate 29 through the through hole on the crushing cylinder 2. The inclined bottom plate 29 guides it to the material retrieval door 30, so that the operator can take out the crushed cotton soft towel raw material by opening the material retrieval door 30.

[0037] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
