Description

Technical Field

[0001] This utility model relates to the technical field of nonwoven fabric processing, and in particular to a pretreatment device for recycled nonwoven fabric materials. Background Technology

[0002] Nonwoven fabric recycling material pretreatment equipment is mainly used to crush, screen, and remove dust from nonwoven fabric scraps or waste materials for subsequent recycling.

[0003] In related technologies, existing pretreatment equipment for recycled nonwoven fabric materials typically includes modules such as conveying, pressing, crushing, and dust removal. During the conveying process, the nonwoven fabric has poor pressing effect, is prone to slipping, and is easily jammed or accumulated during conveying, resulting in unstable feeding. At the same time, the screening efficiency of impurities contained in the nonwoven fabric before processing (crushing) is low. During processing, the crushing rollers mostly rotate synchronously, resulting in low crushing efficiency, easy entanglement of materials, uneven particle size, and generation of fiber dust, which pollutes the environment. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a pretreatment equipment for non-woven fabric recycled materials, which adopts a closed conveying and processing system. Before crushing, it uses two extrusion shaping processes. During the feeding process, it uses vibration screening to remove impurities and simultaneously uses humidification to reduce dust and reduce the bulkiness of the material. Differential crushing and spiral needles are used to enhance the tearing effect, and negative pressure dust removal is used to effectively reduce dust overflow.

[0006] To achieve the above objectives, this utility model proposes a pretreatment device for recycled nonwoven fabric materials, comprising an outer shell, a discharge box, a feeding mechanism, two symmetrically arranged filter mechanisms, an extrusion and shaping mechanism, a guiding and dust-reducing mechanism, and a crushing mechanism. The discharge box is movably connected to the outer shell, the feeding mechanism is located on the outer shell, the two symmetrically arranged filter mechanisms are located on the outer shell, the extrusion and shaping mechanism is located on the outer shell and below the two symmetrically arranged filter mechanisms, the guiding and dust-reducing mechanism is located on the outer shell, and the crushing mechanism includes a first crushing roller, a second crushing roller, needles, and a first driving mechanism. The first crushing roller is rotatably connected to the outer shell, the second crushing roller is rotatably connected to the outer shell and adjacent to the first crushing roller, multiple sets of needles are respectively arranged on the first and second crushing rollers, and the first driving mechanism is located on the outer shell and drives the first and second crushing rollers to rotate synchronously.

[0007] In addition, the nonwoven fabric recycling material pretreatment equipment proposed above according to this utility model may also have the following additional technical features:

[0008] Specifically, the multiple sets of needles are arranged in a spiral shape.

[0009] Specifically, the extrusion shaping mechanism includes a humidification component, two symmetrically arranged extrusion rollers, and a second drive mechanism. The humidification component is disposed on the outer shell and located directly above the two symmetrically arranged extrusion rollers. The two symmetrically arranged extrusion rollers are rotatably connected to the outer shell through the second drive mechanism.

[0010] Specifically, the humidification component includes a third driving device, a pressure box, and two sets of symmetrically arranged nozzles. The pressure box is disposed on the outer casing, the two sets of symmetrically arranged nozzles are disposed on the pressure box, and the third driving device is disposed on the outer casing and connected to the pressure box.

[0011] Specifically, the feeding mechanism includes a feeding pipe, a fourth drive mechanism, a conveyor belt, and multiple pressure rollers. The feeding pipe is disposed on the outer casing, the conveyor belt is rotatably connected to the feeding pipe through the fourth drive mechanism, and the multiple pressure rollers are rotatably connected to the feeding pipe and located above the conveyor belt.

[0012] Specifically, the filter media mechanism includes a filter media screen plate and a support plate, wherein the filter media screen plate is disposed on the outer shell, the filter media screen plate is provided with a vibration motor, and the support plate is disposed on the filter media screen plate and the outer shell, and forms a filter media cavity between the support plate and the outer shell.

[0013] Specifically, the dust collection box is disposed on the outer shell, the fifth driving device is disposed on the dust collection box, and the dust removal filter is disposed on the dust collection box.

[0014] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: The non-woven fabric recycling material pretreatment equipment of this utility model has a feeding mechanism and an outer shell that are connected and sealed together, which enables closed-loop recycling, conveying and processing of non-woven fabric. During the feeding process, the non-woven fabric is initially squeezed. After squeezing, the filter material mechanism is used to vibrate and screen the non-woven fabric to remove impurities. Before crushing, it is squeezed again with the humidification component and the extrusion and shaping mechanism. At the same time, the humidification reduces dust and reduces the bulkiness of the material. During the crushing process, the two crushing rollers rotate at different speeds, and the spiral needles make staggered contact with the non-woven fabric to enhance the tearing and crushing effect. Combined with negative pressure dust removal, it effectively reduces dust overflow, effectively improves the processing efficiency of non-woven fabric, and protects the processing environment.

[0024] 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.

[0025] The following description, in conjunction with the accompanying drawings, describes a pretreatment device for nonwoven fabric recycled materials according to an embodiment of the present invention.

[0026] like Figures 1-6 As shown, the nonwoven fabric recycling material pretreatment equipment of this utility model embodiment may include an outer shell 1, a discharge box 2, a feeding mechanism 3, two symmetrically arranged filter media mechanisms 4, an extrusion and shaping mechanism 5, a guiding dust collection mechanism 6, and a crushing mechanism 7.

[0027] The discharge box 2 is movably connected to the outer shell 1, the feeding mechanism 3 is set on the outer shell 1, two symmetrically arranged filter media mechanisms 4 are set on the outer shell 1, the extrusion and shaping mechanism 5 is set on the outer shell 1 and located below the two symmetrically arranged filter media mechanisms 4, and the guiding dust collection mechanism is set on the outer shell 1.

[0028] It should be noted that, as described in this embodiment, the outer shell 1 can stably support the feeding mechanism 3, the filter mechanism 4, the extrusion and shaping mechanism 5, the guiding dust collection mechanism 6, and the crushing mechanism 7.

[0029] The crushing mechanism 7 includes a first crushing roller 71, a second crushing roller 72, multiple sets of spikes 74, and a first drive mechanism 73.

[0030] The first crushing roller 71 is rotatably connected to the outer shell 1, the second crushing roller 72 is rotatably connected to the outer shell 1 and is arranged adjacent to the first crushing roller 71, multiple sets of needles 74 are respectively arranged on the first crushing roller 71 and the second crushing roller 72, and the first driving mechanism 73 is arranged on the outer shell 1 and drives the first crushing roller 71 and the second crushing roller 72 to rotate synchronously.

[0031] It should be noted that the first drive mechanism 73 proposed in the above embodiment is driven by two pulleys, a belt and a rotary motor. The two pulleys have different diameters, so as to realize the synchronous and co-directional differential rotation of the first crushing roller 71 and the second crushing roller 72.

[0032] Specifically, during the actual nonwoven fabric pretreatment process, relevant personnel energize each part of the device and feed the recycled nonwoven fabric waste into the feed pipe 31 through the feed inlet. The fourth drive mechanism 32 drives the conveyor belt 33 to transport the nonwoven fabric. During the transport process, the nonwoven fabric is initially compressed by multiple pressure rollers 34 and internal impurities (stones) are crushed.

[0033] The initially compressed nonwoven fabric is continuously conveyed, and some of the nonwoven fabric rebounds and deforms, falling sequentially onto the inclined filter material mechanism 4. Through continuous vibration, the impurities and debris contained in the nonwoven fabric are screened out. At the same time, the humidification component 51 is driven to draw in external water and spray it above the extrusion and shaping mechanism 5 to wet the nonwoven fabric, while reducing dust generated by vibration. The wetted nonwoven fabric falls down, and the extrusion and shaping mechanism 5 presses it a second time and continues to convey it downward.

[0034] After secondary extrusion, the nonwoven fabric enters the crushing mechanism 7. Between the first crushing roller 71 and the second crushing roller 72, the two crushing rollers rotate at different speeds through the first driving mechanism 73 to crush the nonwoven fabric. At the same time, the dust generated during crushing is further recovered by the guiding dust collection mechanism 6 to prevent dust from overflowing. Finally, the crushed nonwoven fabric falls into the discharge box 2 to achieve crushed discharge.

[0035] In one embodiment of this utility model, such as Figure 4 and Figure 5 As shown, the needles 74 are arranged in a spiral shape.

[0036] It should be noted that the needles 74 described in this embodiment are arranged in multiple groups and are arranged at equal intervals along the axial direction of the first crushing roller 71 and the second crushing roller 72. The needles 74 between adjacent first crushing rollers 71 and second crushing rollers 72 are staggered to increase shearing force and make the crushed particles more uniform. During crushing, the first crushing roller 71 with a larger diameter crushes with the needles 74, while the second crushing roller 72 with a smaller diameter tears finely, while avoiding non-woven fabric entanglement.

[0037] In one embodiment of this utility model, such as Figure 4 and Figure 5 As shown, the extrusion shaping mechanism 5 includes a humidification component 51, two symmetrically arranged extrusion rollers 52, and a second drive mechanism 53.

[0038] The humidification component 51 is disposed on the outer shell 1 and is located directly above the two symmetrically arranged extrusion rollers 52. The two symmetrically arranged extrusion rollers 52 are rotatably connected to the outer shell 1 through the second drive mechanism 53.

[0039] It should be noted that the second drive mechanism 53 proposed in the above embodiment adopts two meshing gears and a rotary motor. The output end of the rotary motor drives the two meshing gears to rotate in opposite directions, and at the same time drives the two symmetrically arranged extrusion rollers 52 to rotate in opposite directions, extruding the wetted nonwoven fabric and conveying it downward.

[0040] In one embodiment of this utility model, such as Figure 3 , Figure 4 and Figure 6 As shown, the humidification assembly 51 includes a third drive unit 511, a pressure box 512, and two sets of symmetrically arranged nozzles 513.

[0041] The pressure box 512 is mounted on the outer shell 1, two sets of symmetrically arranged nozzles 513 are mounted on the pressure box 512, and the third drive device 511 is mounted on the outer shell 1 and connected to the pressure box 512.

[0042] It should be noted that the third driving device 511 described in this embodiment uses a water pump. The water pump draws water from an external source and pumps it into the pressure box 512. When the water pressure in the pressure box 512 increases, water mist is sprayed downward through the nozzle 513, which acts between the two extrusion rollers 52 to assist in the forming of the extruded nonwoven fabric and at the same time plays a role in dust suppression.

[0043] In one embodiment of this utility model, such as Figure 3 , Figure 4 and Figure 6 As shown, the feeding mechanism 3 includes a feeding pipe 31, a fourth drive mechanism 32, a conveyor belt 33, and multiple pressure rollers 34.

[0044] The feed pipe 31 is mounted on the outer casing 1, the conveyor belt 33 is rotatably connected to the feed pipe 31 via the fourth drive mechanism 32, and multiple pressure rollers 34 are rotatably connected to the feed pipe 31 and located above the conveyor belt 33.

[0045] It should be noted that the fourth drive mechanism 32 proposed in the above embodiment adopts multiple support rollers and a rotary motor. The conveyor belt 33 is sleeved on the outside of the multiple support rollers. When the rotary motor drives one support roller to rotate, the multiple support rollers rotate synchronously. The conveyor belt 33 is used to transport the non-woven fabric above. During the movement, it contacts multiple pressure rollers 34 in sequence to achieve the initial pressing when the non-woven fabric is fed.

[0046] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the filter media mechanism 4 includes a filter media mesh plate 41 and a support plate 42.

[0047] The filter media plate 41 is disposed on the outer shell 1, and a vibration motor 411 is provided on the filter media plate 41. The bearing plate 42 is disposed on the filter media plate 41 and the outer shell 1, and forms a filter media cavity 421 between the bearing plate 42 and the outer shell 1.

[0048] It should be noted that the vibration motor 411 described in this embodiment is set on the bottom wall of the filter media plate 41. After the non-woven fabric is initially pressed and continuously fed, it vibrates after contacting the filter media plate 41. The vibration removes the impurities contained inside. The impurities pass through the filter media plate 41 and fall into the filter media chamber 421. The side wall of the outer shell 1 has a material outlet. By opening the cover plate at the material outlet, the impurities can be cleaned and removed.

[0049] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the guiding dust collection mechanism 6 includes a fifth drive device 61, a dust collection box 62, and a dust removal filter 63.

[0050] The dust collection box 62 is disposed on the outer shell 1, the fifth drive device 61 is disposed on the dust collection box 62, and the dust removal filter 63 is disposed on the dust collection box 62.

[0051] It should be noted that the fifth driving device 61 described in this embodiment uses an air pump, and the dust collection box 62 is connected to the outside of the outer shell 1. The air pump generates suction to guide and absorb the dust generated during the crushing and feeding process. The dust filter 63 filters the flowing air, creating negative pressure inside the outer shell 1 to reduce dust overflow.

[0052] In summary, the nonwoven fabric recycling material pretreatment equipment of this utility model adopts closed conveying and processing, and uses two extrusion shaping before crushing. During the feeding process, vibration screening removes impurities, and at the same time, it is combined with humidification to reduce dust and reduce the bulkiness of the material. Differential crushing and spiral needles enhance the tearing effect, and negative pressure dust removal effectively reduces dust overflow.
