Description

Technical Field

[0001] The invention relates to the technical field of sterilization of mesh-free cotton tire products, in particular to a sterilization device for mesh-free cotton tire products. Background Art

[0002] The meshless cotton batting is a special quilt product, which is characterized in that the surface of the cotton batting is not reinforced with a mesh, but a stable reinforcement structure is formed by utilizing the characteristics of the cotton fiber itself. The production process of the meshless cotton batting usually includes the steps of opening, cleaning, combing, laying, compression molding, etc.; in the prior art, recycled old cotton products can be used as raw materials to produce cotton batting products. The recycled cotton products usually need to be dispersed into cotton clumps first, and then the cotton clumps are sterilized by high-temperature steam. Finally, the sterilized cotton clumps can be loosened and dispersed by a roller with spikes evenly covered on the surface, so that the recycled cotton products can be put into production as cotton batting raw materials.

[0003] However, the existing method of sterilizing recycled cotton products has the following problems: 1. When the recycled cotton clumps are sterilized with high-temperature steam, since the recycled cotton clumps are severely compacted and the gaps between the cotton fibers are small, it takes a long time for the steam to penetrate into the cotton clumps, the efficiency is low and the uniformity is poor, resulting in high cost and poor quality of the overall sterilization of the recycled cotton clumps; 2. In the prior art, the cotton clumps are generally first steam sterilized, and then the sterilized cotton clumps are loosened and dispersed. This operation method results in poor continuity in the overall operation process of the sterilization treatment of the cotton clumps and subsequent production and processing, resulting in low sterilization efficiency of the cotton batting products and the overall production and processing.

[0032] See also Figure 2 and Figure 3 The feeding mechanism 4 includes a feeding box 41, an air intake pipe 42, a guide groove 43, a limiting wedge block 44, a driving assembly 45 and a pushing assembly 46; the feeding box 41 is fixedly arranged on the rear side of the sterilization box 1, and the air intake pipe 42 is fixedly arranged on the lower sides of the sterilization box 1 and the feeding box 41 symmetrically, and a filter is fixedly arranged on the upper end of the air intake pipe 42. A feeding port is provided on the rear surface of the feeding box 41, and guide grooves 43 are symmetrically arranged on the left and right sides of the inside of the feeding box 41. A limiting wedge block 44 is fixedly arranged at the front end of the guide groove 43, a driving assembly 45 is arranged on the feeding box 41, and a pushing assembly 46 is arranged in the feeding box 41.

[0033] See also Figure 2 and Figure 3 The driving assembly 45 includes an electric push rod 451, a U-shaped frame 452, a connecting rod 453 and a spring rod 454; an electric push rod 451 is fixedly provided on the upper side of the feed box 41 through a plate 1, a U-shaped frame 452 is fixedly provided on the telescopic end of the electric push rod 451, a connecting rod 453 is fixedly provided on the front side of the upper end of the U-shaped frame 452 symmetrically, and a spring rod 454 is fixedly provided on the front end of the connecting rod 453 through a plate 2.

[0034] See also Figure 2 , Figure 3 and Figure 4 The pushing assembly 46 includes an L-shaped pushing plate 461, a spring sleeve 462 and a clamp 463; the lower end of the spring rod 454 is elastically slidably provided with an L-shaped pushing plate 461, and the rear side of the horizontal section of the L-shaped pushing plate 461 is symmetrically fixed with a spring sleeve 462, and a clamp 463 that slides with the guide groove 43 is elastically slidably provided inside the spring sleeve 462.

[0035] When the recovered cotton clumps are to be stably conveyed into the sterilization box 1, the cotton clumps are first continuously put into the feed box 41 from the feed port, and high-temperature steam can be simultaneously introduced into the feed box 41 through the air intake pipe 42 on the lower side of the feed box 41 to perform steam pretreatment and sterilization on the cotton clumps. At the same time, the electric push rod 451 drives the U-shaped frame 452 to move back and forth a specific distance, and the connecting rod 453 drives the L-shaped push plate 461 and the clamp 463 to move back and forth along the guide groove 43.

[0036] When the L-shaped push plate 461 and the clamping member 463 move to the front end along the horizontal section of the guide groove 43, the clamping member 463 is first retracted into the spring sleeve 462 under the action of the inclined surface of the rear end of the limiting wedge block 44 until the clamping member 463 completely passes over the limiting wedge block 44. At this time, the clamping member 463 is extended again under the elastic action of the spring sleeve 462 and is clamped into the front end of the guide groove 43. At the same time, the limiting wedge block 44 uses the vertical surface of the front end to make the clamping member 463 and the L-shaped push plate 461 move backward only along the inclined section of the guide groove 43, so that the L-shaped push plate 461 moves upward synchronously along the inclined section of the guide groove 43 under the backward drive of the electric push rod 451.

[0037] When the L-shaped push plate 461 moves to the rear end of the inclined section of the guide groove 43, under the elastic action of the spring rod 454, the L-shaped push plate 461 moves downward along the vertical section of the guide groove 43 to the lowest end. At this time, the vertical section of the L-shaped push plate 461 just moves to the rear side of the cotton cluster in the feed box 41, so that the L-shaped push plate 461 is driven forward by the electric push rod 451, so that the L-shaped push plate 461 can move forward along the horizontal section of the guide groove 43 and simultaneously push the cotton cluster on the front side quickly and stably into the sterilization box 1. This operation mode not only ensures the efficiency and stability of feeding the cotton cluster during the sterilization process, but also pre-treats and sterilizes the cotton cluster with high-temperature steam while conveying it, thereby improving the overall sterilization efficiency and effect of the cotton cluster.

[0038] See also Figure 1 , Figure 2 and Figure 3The opening mechanism 5 includes a motor 51, a licker-in roller 52, a material return assembly 53, a licker-in roller 54, a scraper 55 and a connecting rod 56; a motor 51 is fixedly arranged on the right side of the sterilizing box 1, a licker-in roller 52 is symmetrically arranged in the middle part of the sterilizing box 1, a material return assembly 53 is arranged on the upper side of the licker-in roller 52, a licker-in roller 54 is symmetrically arranged in the lower side of the licker-in roller 52 in the sterilizing box 1, and a licker-in roller 54 is symmetrically arranged in the lower side of the licker-in roller 52. They are all connected through a pulley structure transmission, wherein the front side of the licker-in roller 1 52 and the licker-in roller 2 54 are connected through a gear structure transmission, wherein the right end of the front side of the licker-in roller 2 54 is fixedly connected to the driving end of the motor 1 51, and the lower side of the licker-in roller 2 54 is provided with a scraper 1 55 that moves forward and backward, and the rear side of the scraper 1 55 is symmetrically fixed with a connecting rod 2 56, and the rear ends of the symmetrical connecting rod 2 56 are respectively fixedly connected to the lower ends of the vertical sections on the left and right sides of the U-shaped frame 452.

[0039] The front licker-in roller 2 54 is driven by the motor 1 51 to rotate counterclockwise (such as Figure 2 As shown in the figure, the front licker-in roller 1 52 rotates synchronously clockwise under the transmission of the gear structure, and the rear licker-in roller 1 52 and licker-in roller 2 54 rotate synchronously and in the same direction as the front licker-in roller 1 52 and licker-in roller 2 54 respectively under the transmission of the pulley structure.

[0040] When the cotton mass transported into the sterilizing box 1 contacts the licker-in roller 1 52 and the licker-in roller 2 54, the licker-in roller 1 52 and the licker-in roller 2 54 rotate synchronously in opposite directions. Therefore, the cotton mass can be continuously and rapidly pulled in two opposite directions, upward and downward, to be loosened, so that the cotton mass can be quickly dispersed into fibers in the sterilizing box 1. At the same time, high-temperature steam is introduced into the sterilizing box 1 through the air inlet pipe 42 at the lower side of the sterilizing box 1, so that the loosened and dispersed cotton fibers can be sterilized synchronously by steam. , and the scraper 1 55 on the lower side of the licker-in roller 54, which moves back and forth synchronously with the U-shaped frame 452, can continuously clean the filter screen at the upper end of the air inlet pipe 42, so as to prevent the cotton fibers from clogging the filter screen. This simultaneous operation mode of loosening, dispersing and steam sterilization not only improves the sterilization treatment of cotton products and the continuity of the overall production and processing operation process, but also greatly improves the speed and uniformity of steam penetration into cotton fibers, thereby reducing the time consumed in the sterilization treatment of cotton agglomerations and improving the overall sterilization efficiency and quality of cotton agglomerations.

[0041] See also Figure 2 , Figure 3 and Figure 6The return material assembly 53 includes an L-shaped bracket 531, a conveying roller 532, a conveying belt 533, a gear 534 and a rack 535; an L-shaped bracket 531 is fixedly arranged on the upper side of the licker-in roller 52 in the sterilization box 1, and a conveying roller 532 is symmetrically rotated front and back on the upper side of the L-shaped bracket 531 in the sterilization box 1, and a conveying belt 533 is jointly driven on the surfaces of the front and rear symmetrical conveying rollers 532, wherein gears 534 are symmetrically fixedly arranged at both ends of the conveying roller 532 on the front side, and a rack 535 that moves up and down is meshed with the rear side of the gear 534.

[0044] The licker-in roller 1 52 and the licker-in roller 2 54 can not only quickly loosen and disperse the cotton clumps by rotating in coordination, but also continuously transport the cotton clumps and cotton fibers in reverse to the discharge port 2, and the negative pressure fan 3 can quickly output the sterilized cotton fibers from the discharge port 2 through negative pressure, while the large cotton clumps that are not completely loosened and dispersed will be blocked and grasped by the U-shaped comb teeth 614 on the front side of the licker-in roller 1 52 and the licker-in roller 2 54, and the tooth hooks on the U-shaped comb teeth 614 can ensure the stability of combing and grasping the cotton clumps.

[0045] See also Figure 2 and Figure 5 The lifting assembly 62 includes a connecting plate 2 621, an L-shaped pressure plate 622 and a driven shaft 623; the upper ends of the connecting rods 3 611 are fixedly provided with a connecting plate 2 621, the middle section of the connecting plate 2 621 is fixedly provided with an L-shaped pressure plate 622, the rear side of the vertical section of the L-shaped pressure plate 622 is fixedly provided with a driven shaft 623, and the two ends of the connecting plate 2 621 are symmetrically fixedly connected with a rack 1 535 through L-shaped plate 3.

[0047] See also Figure 2 and Figure 5 The linkage assembly 64 includes a gear 2 641, a rack 3 642, a connecting plate 4 643, a spring rod 2 644, a fixing frame 645 and a driven wheel 646; a gear 2 641 meshing with the rack 2 633 is symmetrically rotated on the upper side of the sterilization box 1 through a support 1, and a rack 3 642 that moves forward and backward is meshed on the upper side of the gear 2 641. A connecting plate 4 643 is fixed between the rear ends of the rack 3 642, and a spring rod 2 644 is symmetrically fixed on the front side of the connecting plate 4 643.

The upper end of the fixing frame 645 is rotatably provided with a driven wheel 646 that cooperates with the L-shaped pressure plate 622 for transmission.

[0048] When the L-shaped pushing plate 461 moves backward a certain distance along the inclined section of the guide groove 43, most of the cotton clumps pushed into the sterilization box 1 have been loosened, and the unopened cotton clumps have been combed and grasped by the U-shaped comb teeth 614. At this time, the driving mechanism 7 drives the driven shaft 623 to drive the L-shaped pressing plate 622 and the connecting plate 621 to achieve a fixed distance of reciprocating movement up and down before the L-shaped pushing plate 461 pushes a part of the cotton clumps into the sterilization box 1 again.

[0049] When the connecting plate 2 621 is driven upward by the driving mechanism 7 and drives the L-shaped slide 612 upward to the uppermost end inside the sterilization box 1 through the connecting rod 3 611, the L-shaped slide 612 and the U-shaped comb teeth 614 cannot continue to move upward, while the connecting rod 3 611 and the L-shaped pressure plate 622 can still continue to move upward a certain distance, and the inclined section of the L-shaped pressure plate 622 that continues to move upward can gradually drive the fixed frame 645 to move forward a specific distance by pressing the driven wheel 646. In the process of the fixed frame 645 moving forward, the rack 3 642 moves forward synchronously and meshes with the gear 2 641 for transmission, and the gear 2 641 drives the rack 2 633 to move backward synchronously through the meshing transmission. When the fixed frame 645 moves to the front end, the rack 2 633 drives the connecting rod 4 632 to move to the rear end along the straight groove 631 under the meshing transmission of the gear 2 641.

[0050] When the U-shaped comb teeth 614 cannot move further upward, the scraper plate 2 636 is aligned with the gap between the U-shaped comb teeth 614, and the rack 1 535 that moves upward synchronously with the connecting plate 2 621 is disengaged from the gear 1 534. When the connecting rod 4 632 moves backward under the indirect drive of the L-shaped pressure plate 622 that continues to move upward, the scraper plate 2 636 moves backward synchronously therewith and inserts into the gap between the U-shaped comb teeth 614 to scrape off the large pieces of cotton clumps attached to the U-shaped comb teeth 614, and the scraped cotton clumps fall on the upper surface of the conveyor belt 533.

[0051] When the L-shaped pressing plate 622 and the connecting plate 2 621 move downward a specific distance under the drive of the driving mechanism 7, the inclined section of the L-shaped pressing plate 622 is separated from the driven wheel 646, and the fixing frame 645 moves backward and resets under the action of the spring rod 2 644, and the scraper 2 636 also moves forward and resets under the drive of the rack 3 642. At the same time, the L-shaped slide 612 and the U-shaped comb teeth 614 start to move downward under the drive of the connecting rod 3 611, and the rack 1 535 is meshed with the gear 1 534 again. When the connecting plate 2 621 drives the U-shaped comb teeth 614 to continue to move downward through the connecting rod 3 611, the rack 1 535 is also meshed with the gear 1 534. The conveyor roller 532 meshes with the gear 534 for transmission, and rotates accordingly, driving the conveyor belt 533 to convey backwards until the U-shaped comb teeth 614 are reset again, thereby conveying the cotton clumps that have fallen on the conveyor belt 533 to the front side of the L-shaped pushing plate 461 again. At this time, the L-shaped pushing plate 461 also starts to move forward to push the material. This operation method can comb and capture large cotton clumps that have not been completely loosened and dispersed, and return them to the feed box 41 again to achieve secondary conveying and loosening and sterilization, which not only ensures the stability and consistency of the overall loosening and dispersion of the cotton clumps, but also ensures the uniformity and quality of the overall sterilization of the cotton clumps.
