Description

Technical Field

[0001] This utility model relates to the technical field of crushing devices, and in particular to a crushing device for non-woven fabric recycled fibers. Background Technology

[0002] Nonwoven fabric, also known as non-woven cloth, is mainly composed of polymer materials such as polypropylene (PP) and polyester (PET). This material does not require traditional spinning and weaving processes, but is formed by directly bonding, fusing, or mechanically interlacing fibers through physical or chemical methods to create a flexible material.

[0003] Currently, the production and trimming process of nonwoven fabrics generates a large amount of waste. To reduce "white pollution" and lower raw material costs, waste recycling is typically carried out. This process requires the use of crushing equipment to break down the nonwoven fabric for subsequent reprocessing. However, existing crushing equipment generates a large amount of dust during the crushing process. This dust permeates the processing workshop, not only adhering to the workers' clothing but also being inhaled, posing a threat to their health. Utility Model Content

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] The nonwoven fabric recycling fiber crushing device of this utility model is described below with reference to the accompanying drawings.

[0021] The nonwoven fabric recycling fiber crushing device provided in this embodiment can be applied to the recycling and processing of nonwoven fabric waste. It can effectively reduce the diffusion of dust during the crushing process, thereby reducing the risk of workers inhaling dust and protecting their health.

[0022] like Figures 1-3 As shown, the nonwoven fabric recycled fiber crushing device of this utility model embodiment may include a mounting frame 1, a feeding dust suppression component 2, a crushing dust suppression mechanism 3, and a discharge component 4.

[0023] As a possible alternative, self-locking casters can be installed at the bottom of the mounting frame 1 described in the above embodiments to facilitate the movement of the crushing device.

[0024] The feeding dust suppression component 2 is mounted on the mounting frame 1. The feeding dust suppression component 2 may include a crushing bin 21, a feeding pipe 22, a feeding pipe 23, a negative pressure fan 24, an air duct 25, and a water pipe 26.

[0025] It should be noted that a conveying auger (not shown in the figure) can be installed inside the feeding pipe 22 described in the above embodiments to facilitate the conveying of non-woven fabric waste.

[0026] It should be noted that a valve (not shown in the figure) can be installed on the water pipe 26 and electrically connected to the timing control device (not shown in the figure) to achieve the effect of intermittent water supply through the water pipe 26, thereby avoiding the situation where the non-woven fabric fibers have a high water content and are difficult to discharge due to continuous water supply during the crushing process.

[0027] The crushing chamber 21 is mounted on the mounting frame 1. The feeding pipe 22 is connected to the crushing chamber 21 through the feed pipe 23. The negative pressure fan 24 is installed on one side of the crushing chamber 21, and the output end of the negative pressure fan 24 is connected to the feed pipe 23 through the air duct 25. The air duct 25 is set towards the crushing chamber 21. The water pipe 26 is set at the bottom of the crushing chamber 21 and is connected to the crushing and dust suppression mechanism 3.

[0028] It should be noted that the water pipe 26 described in the above embodiment is connected to a water pump (not shown in the figure).

[0029] Specifically, under the action of the feeding pipe 22, the non-woven fabric waste is discharged into the crushing chamber 21 through the feeding pipe 23. Then, under the action of the negative pressure fan 24, air is discharged into the feeding pipe 23 through the air duct 25. This assists in feeding the non-woven fabric waste while preventing dust from being discharged through the feeding pipe 23 and the feeding pipe 22 during the crushing process, thus ensuring the health of the workers. Subsequently, under the action of the water pipe 26, water is discharged into the crushing chamber 21 through the crushing dust suppression mechanism 3 to suppress the dust generated during the crushing process.

[0030] The crushing and dust suppression mechanism 3 is mounted on the mounting frame 1. The crushing and dust suppression mechanism 3 may include a drive motor 31, a connecting sprocket 32, a chain 33, a drive sprocket 34, a crushing and dust suppression component 35, and a limiting component 36.

[0031] It should be noted that the limiting component 36 described in the above embodiments is provided in multiple sets.

[0032] The drive motor 31 is mounted on the mounting frame 1. The connecting sprocket 32 ​​and the drive sprocket 34 are both rotatably mounted at the bottom of the crushing chamber 21. The drive sprocket 34 is connected to the output end of the drive motor 31. The drive sprocket 34 is connected to the connecting sprocket 32 ​​via the chain 33. The crushing and dust suppression component 35 and the limiting component 36 are both located inside the crushing chamber 21. The crushing and dust suppression component 35 is connected to the connecting sprocket 32, and the limiting component 36 is in contact with the crushing and dust suppression component 35.

[0033] Specifically, under the action of the drive motor 31, the connecting sprocket 32 ​​is driven by the drive sprocket 34 and the chain 33. At the same time as the connecting sprocket 32 ​​rotates, the crushing and dust suppression component 35 rotates in the crushing chamber 21, thereby completing the step of crushing non-woven fabric waste. The crushing and dust suppression component 35 atomizes the water conveyed by the limiting component 36 and sprays it into the crushing chamber 21 to avoid dust spreading during the crushing process. Subsequently, under the action of the limiting component 36, the non-woven fabric waste is prevented from getting entangled on the crushing and dust suppression component 35, which would result in poor crushing quality.

[0034] The discharge assembly 4 is mounted on the mounting frame 1 and is connected to the crushing chamber 21.

[0035] Understandably, the discharge component 4 is used to discharge the crushed nonwoven fibers.

[0036] Specifically, in actual operation, when crushing non-woven fabric waste, the relevant personnel discharge the waste into the feed pipe 23 through the feed pipe 22. With the help of the negative pressure fan 24 and the air duct 25, the waste enters the crushing chamber 21. Simultaneously, the air ejected from the air duct 25 forms an air screen at the feed pipe 23 to prevent dust from being discharged through the feed pipe 23 and feed pipe 22 during the crushing process. Then, under the action of the water pipe 26, the waste is transported to the crushing dust suppression component 35. At the same time, the drive motor 31 drives the sprocket 34 and chain 3... 3 drives the connecting sprocket 32. During the rotation of the connecting sprocket 32, the crushing and dust suppression component 35 rotates together. During the rotation of the crushing and dust suppression component 35, the non-woven fabric waste is crushed and dust is suppressed. Under the action of the limiting component 36, the non-woven fabric waste is prevented from getting entangled on the crushing and dust suppression component 35. After crushing, the non-woven fabric waste is extracted by the discharge component 4 and the feeding step is completed. In this way, the diffusion of dust during the crushing process can be effectively reduced, thereby reducing the risk of workers inhaling dust and protecting the health of workers.

[0037] In one embodiment of this utility model, such as Figure 2 As shown, the crushing and dust suppression assembly 35 includes a crushing rod 351, a crushing blade 353, and a flat blade 354.

[0038] It should be noted that the crushing blade 353 described in the above embodiments is provided in multiple sets.

[0039] The crushing rod 351 is connected to the connecting sprocket 32. The crushing blade 353 and the flat blade 354 are both connected to the crushing rod 351. The flat blade 354 is located below the crushing blade 353. The crushing chamber 21 is equipped with a filter plate, and the flat blade 354 is in contact with the filter plate. The crushing rod 351 has a hollow structure and multiple sets of atomizing holes 352 are opened on the crushing rod 351. The water pipe 26 is rotatably connected to the crushing rod 351.

[0040] It should be noted that the bottom end of the flat blade 354 described in the above embodiment contacts the filter plate, thereby completing the further crushing of the non-woven fabric waste on the filter plate and improving the crushing effect of the non-woven fabric waste.

[0041] Specifically, when the crushing rod 351 rotates, the crushing blade 353 and the flat blade 354 complete the crushing of the non-woven fabric waste. When the crushing rod 351 rotates, the water transported by the water pipe 26 is sprayed out in the form of atomization through the atomization hole 352, thereby achieving dust suppression of non-woven fabric dust during the crushing process.

[0042] In one embodiment of this utility model, such as Figure 2 As shown, the limiting component 36 may include a cleaning rod 361 and a limiting plate 362.

[0043] It should be noted that the limiting plate 362 is set on both sides of the crushing blade 353 and the flat blade 354.

[0044] The cleaning rod 361 is installed inside the crushing chamber 21, and one end of the cleaning rod 361 is in contact with the crushing rod 351. The limiting plate 362 is installed on the cleaning rod 361.

[0045] Specifically, the cleaning rod 361 cleans the non-woven fabric wrapped around the crushing rod 351 and accumulates it on the cleaning rod 361. The limiting plate 362 prevents the non-woven fabric from continuously accumulating on the cleaning rod 361, so that the crushing blade 353 and the flat blade 354 can contact the non-woven fabric on the cleaning rod 361 and continuously crush the non-woven fabric accumulated on the cleaning rod 361.

[0046] In one embodiment of this utility model, such as Figures 1-2 As shown, the discharge assembly 4 may include a discharge fan 41, an O-shaped hopper 42, a support plate 43, and a discharge pipe 44.

[0047] It should be noted that the top of the O-shaped chamber 42 described in the above embodiment is connected to an exhaust valve (not shown in the figure), thereby completing the discharge of gas from the O-shaped chamber 42.

[0048] It should be noted that a constant temperature heating plate (not shown in the figure) can be installed in the O-shaped chamber 42 described in the above embodiment to dry the slightly damp non-woven fabric fibers.

[0049] Among them, the discharge fan 41 is installed on the mounting frame 1, the feed end of the discharge fan 41 is connected to the crushing chamber 21, the O-shaped chamber 42 is set on the mounting frame 1 through the support plate 43, the discharge end of the discharge fan 41 is connected to the O-shaped chamber 42, and the discharge pipe 44 is connected to the top of one side of the O-shaped chamber 42.

[0050] Specifically, under the action of the discharge fan 41, the pulverized nonwoven fabric fibers are discharged into the O-shaped chamber 42 supported by the support plate 43 and circulate in the O-shaped chamber 42. During the discharge process of the discharge fan 41, air enters the O-shaped chamber 42 together, thereby completing the air drying treatment of the slightly moist nonwoven fabric fibers, and after air drying, the nonwoven fabric fibers are discharged through the discharge pipe 44.

[0051] In one embodiment of this utility model, such as Figure 1 As shown, the O-shaped compartment 42 is mounted above the support plate 43 with a shielding assembly 5. The shielding assembly 5 may include a support frame 51, a cylinder 52, a baffle 53 and a sealing strip 54.

[0052] The support frame 51 is installed on the O-shaped chamber 42, the cylinder 52 is installed on the support frame 51, the baffle 53 is connected to the extended end of the cylinder 52, the O-shaped chamber 42 is provided with a through groove for the baffle 53 to pass through, and the sealing strip 54 is installed on one side of the through groove, with the baffle 53 passing through the sealing strip 54.

[0053] Specifically, the cylinder 52 is installed under the action of the support frame 51. Then, under the drive of the cylinder 52, the baffle 53 seals the O-shaped chamber 42, thereby assisting the non-woven fabric fibers to be discharged through the feed pipe 44 after air drying. Under the action of the sealing strip 54, the non-woven fabric fibers are prevented from being discharged through the connection between the sealing strip 54 and the O-shaped chamber 42.

[0054] In summary, the nonwoven fabric recycling fiber crushing device of this utility model can effectively reduce the diffusion of dust during the crushing process, thereby reducing the risk of workers inhaling dust and protecting their health.
