[0050] The present invention will be further described below with reference to the drawings and embodiments

[0051] First embodiment:

[0052] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , where Figure 1 is the three-dimensional view of the first embodiment of the production device for recycling and regenerating nylon waste silk pellets provided by the present invention Figure 2 is Figure 1 the overall cross-sectional view shown Figure 3 is Figure 1 the three-dimensional view of the drainage frame part shown Figure 4 is Figure 2 the schematic structural diagram of the roller pressing mechanism part shown

[0053] A production device for recycling and regenerating nylon waste silk pellets includes:

[0054] A water washing tank 1, an installation cover 11 is fixedly installed on the top of the water washing tank 1, and a cleaning liquid 100 is filled in the water washing tank 1

[0055] A conveyor belt 2, wherein the conveyor belt 2 is installed in the washing tank 1, and the cleaning liquid 100 half-submerges the conveyor belt 2;

[0056] A traction shaft 3, wherein the traction shaft 3 is fixedly mounted on the conveyor belt 2;

[0057] A flow guide frame 4, wherein the flow guide frame 4 is fixedly mounted on the mounting cover 11, the flow guide frame 41 is an arc-shaped structure, and the bottom end of the flow guide frame 4 is slidably connected to the conveyor belt 2, and the flow guide frame 4 and the traction shaft 3 are staggered;

[0058] A fixed box 5, wherein the fixed box 5 is fixedly installed on the washing tank 1;

[0059] The rolling mechanism 6 includes a mounting frame 61, a driving motor 62, a first pulley 63, a belt 64, a second pulley 65 and a pressing roller 66. The mounting frame 61 is fixedly mounted on the fixed box 5. The driving motor 62 is fixedly mounted on the mounting frame 61. The first pulley 63 is fixedly mounted on the shaft end of the driving motor 62. The second pulley 65 is installed on the surface of the first pulley 63 through a belt 64. The pressing roller 66 is fixedly mounted on the shaft end of the second pulley 65. The shaft end of the pressing roller 66 is rotatably mounted on the mounting frame 61, and the pressing roller 66 matches the drainage frame 4.

[0060] By adding a conveyor belt 2 in the washing tank 1, the conveyor belt 2 can conveniently transfer the waste nylon waste silk to below the liquid level of the cleaning liquid 100 through the traction shaft 3, so as to achieve complete immersion washing. After immersion washing, it is automatically transferred upward through the drainage rack 4. During transportation, it is automatically rolled and dehydrated by the rolling mechanism 6. After dehydration, it is convenient to automatically discharge the material from between the fixed box 5 and the installation cover 11, so that the waste nylon waste silk can be dehydrated and discharged at the same time as washing.

[0061] During washing, the waste nylon yarn is preferentially transported from the top of the washing tank 1 to the top of the conveyor belt 2, and the traction shaft 3 cooperates with the conveyor belt 2 to pull the nylon waste yarn to below the liquid surface of the cleaning liquid 100 for cleaning and transportation, and then cleaned and transported to the drainage rack 4. The drainage rack 4 drains the cleaned nylon waste yarn upward, and the pressing roller 66 rotates and assists in draining the nylon waste yarn while realizing roller dehydration to ensure the stability of the nylon waste yarn transmission. The nylon waste yarn after roller dehydration continues to be transported upward to the gap between the fixed box 5 and the mounting cover 11, and is discharged from the gap to provide stable support for subsequent processing operations.

[0062] Please refer again Figure 2 When the conveyor belt 2 is working, it conveys in the clockwise direction, and when the roller mechanism 6 is working, it roller-presses and conveys in the counterclockwise direction.

[0063] The top of the water washing tank 1 is open, and an installation cover 11 is fixed above it, and the inside is filled with a cleaning liquid 100;

[0064] In an alternative embodiment, the cleaning liquid 100 may be equipped with a circulating flow device for circulating the cleaning liquid 100 from one side of the water washing tank 1 to the other side to ensure the fluidity of the cleaning liquid 100.

[0065] The conveyor belt 2 adopts an existing belt conveying mechanism and is installed in the water washing tank 1 to provide a stable power source for the conveying of polyamide waste silk.

[0066] A plurality of traction shafts 3 are provided and are arranged in an array on the conveyor belt 2. They can move along with the movement of the conveyor belt 2 and will not collide or rub against the surface of the drainage frame 4 while the traction shafts 3 are moving.

[0067] The bottom of the drainage frame 4 is provided with a through hole, and the surface of the traction shaft 3 matches the through hole and can pass through the through hole when the traction shaft 3 moves.

[0068] The driving motor 62 is a stepping motor. When in use, it is connected to an external power source to provide a power source for the rotation of the first pulley 63. The first pulley 63 is connected to the second pulley 65 through a belt 64 to achieve synchronous rotation of the first pulley 63 and the second pulley 65. The shaft end of the second pulley 65 is fixedly connected to the shaft end of the pressing roller 66. The second pulley 65 can drive the pressing roller 66 to rotate synchronously. The rotation direction of the pressing roller 66 is the same as the drainage direction of the polyamide waste silk on the drainage frame 4 to ensure the stability of the transmission and roller pressing of the polyamide waste silk.

[0069] The pressing roller 66 is of a rubber structure with a diameter of 80 - 100 mm.

[0070] One side of the fixed box 5 is open. The mounting frame 61 is slidably mounted on the fixed box 5. It further includes a telescopic member 7. One end of the telescopic member 7 is fixedly installed inside the fixed box 5, and the other end of the telescopic member 7 is fixedly installed on the mounting frame 61.

[0071] The telescopic member 7 facilitates driving the mounting frame 61 to move and adjust. When the mounting frame 61 moves, it facilitates driving the pressing roller 66 to adjust its position, thereby facilitating the adjustment of the roller pressing degree during roller pressing to meet the stable roller pressing and transmission of polyamide waste silk with different water washing amounts.

[0072] The telescopic member 7 can be an electric telescopic rod, a hydraulic cylinder, and a telescopic air cylinder. Preferably, it is an electric telescopic rod. When in use, it is connected to an external power source to provide a stable power source for the expansion and contraction of the mounting frame 61.

[0073] When the pressing roller 66 is fully retracted, the gap between the drainage frame 4 and the pressing roller 66 can be effectively increased, which is convenient for maintaining the equipment and reducing the phenomenon of wire jamming at the connection.

[0074] The traction shaft 3 is made of rigid plastic and has a diameter of 12 mm.

[0075] The drainage frame 4 is made of stainless steel, with a thickness of 10 - 20 mm and a bottom opening width of 13 - 14 mm.

[0076] The working principle of the production device for recycling and regenerating nylon waste filaments provided by the present invention is as follows:

[0077] When it is necessary to clean the nylon waste filaments, the telescopic member 7 is started in advance. The telescopic member 7 drives the roller pressing mechanism 6 to extend as a whole, and the roller pressing mechanism 6 is aligned within the drainage frame 4;

[0078] The nylon waste filaments are conveyed above the conveyor belt 2, and the conveyor belt 2 and the roller pressing mechanism 6 are started;

[0079] The nylon waste filaments are washed by rolling along the conveyor belt 2 in the clockwise direction through the traction shaft 3. After washing, they are upwardly drained and transmitted through the drainage frame 4. During the transmission, dehydration is achieved through the running pressing roller 66, and after dehydration, they continue to be upwardly conveyed and discharged.

[0080] Compared with the related art, the production device for recycling and regenerating nylon waste filaments provided by the present invention has the following

[0081] Beneficial effects:

[0082] By adding the conveyor belt 2 in the water washing tank 1, the conveyor belt 2 can conveniently convey the waste nylon waste filaments below the liquid level of the cleaning liquid 100 through the traction shaft 3, realizing complete immersion water washing. After immersion water washing, they are automatically upwardly transmitted through the drainage frame 4. During the transmission, dehydration is automatically carried out through the roller pressing mechanism 6, and after dehydration, it is convenient to automatically discharge from between the fixed box 5 and the mounting cover 11, so as to facilitate dehydration and discharging while washing the waste nylon waste filaments.

[0083] Second Embodiment:

[0084] Please refer to Figure 5 and Figure 6 , based on a production device for recycling and regenerating nylon waste filaments provided by the first embodiment of the present application, the second embodiment of the present application proposes another production device for recycling and regenerating nylon waste filaments. The second embodiment is only a preferred manner of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0085] Specifically, the difference of the nylon waste silk recycling and regeneration granule production device provided by the second embodiment of the present application lies in that the nylon waste silk recycling and regeneration granule production device further includes a drying mechanism 8. The drying mechanism 8 includes a connecting pipe 81 and a blower 82. The connecting pipe 81 is fixedly installed on the mounting cover 11. The connecting pipe 81 is communicated with the inside of the mounting cover 11. The connecting pipe 81 has a structure that penetrates up and down, and a blower 82 is installed inside the connecting pipe 81. The output end of the blower 82 faces the inside of the mounting cover 11.

[0086] By installing the drying mechanism 8 on the mounting cover 11, when the nylon waste silk is transferred between the mounting cover 11 and the fixed box 5 after being washed, the drying mechanism 8 can blow-dry the dehydrated nylon waste silk, reducing the construction of separate drying equipment, increasing the drying efficiency and production synchronization, and enabling automatic drying after the nylon waste silk is washed.

[0087] During drying, the nylon waste silk is transferred between the fixed box 5 and the mounting cover 11, and the blower 82 is started. The blower 82 blows and dries the nylon waste silk.

[0088] In an optional manner, it further includes an electric heating wire 83. The electric heating wire 83 is fixedly installed on the connecting pipe 81, and the electric heating wire 83 is installed in the output direction of the blower 82. By installing the electric heating wire 83 at the output end of the blower 82, the temperature during blow-drying is increased, and the temperature range is 45 - 50 °C, improving the drying efficiency and quality of the nylon waste silk.

[0089] The electric heating wire 83 adopts existing electric heating equipment for controlling the blowing temperature. The control principle and related technologies are relatively mature in the prior art and do not need to be elaborated here too much.

[0090] A transparent window 51 is inlaid and installed on the fixed box 5. It further includes an ultraviolet irradiation lamp 9. The ultraviolet irradiation lamp 9 is fixedly installed on the mounting frame 61. The irradiation range of the ultraviolet irradiation lamp 9 matches the transparent window 51. By installing the ultraviolet irradiation lamp 9 on the mounting frame 61, ultraviolet rays can pass through the transparent window 51 and irradiate the transferred nylon waste silk, realizing disinfection and sterilization of the nylon waste silk, and improving the safety and quality of the recycled nylon waste silk after washing.

[0091] The ultraviolet irradiation lamp 9 is an existing ultraviolet lamp structure, which is connected to an external power supply during use to provide an ultraviolet irradiation light source.

[0092] The pressing roller 66 has a transparent structure throughout, and the pressing roller 66 is installed within the irradiation range of the ultraviolet irradiation lamp 9. Through the transparent pressing roller 66, it is convenient to perform ultraviolet irradiation and sterilization on the cotton yarn while rolling and dehydrating the nylon waste silk, making the ultraviolet irradiation more uniform and sufficient.

[0093] The pressing of the pressing roller 66 can make the nylon waste silk evenly distributed on the surface of the pressing roller 66, so as to achieve full ultraviolet irradiation sterilization. Compared with direct irradiation, it can play a more comprehensive and reliable irradiation function.

[0094] The working principle of the nylon waste silk recycling and regenerating granule production device provided in this embodiment:

[0095] When it is necessary to dry the nylon waste silk, start the electric heating wire 83 and the blower 82. The blower 82 blows air to the heating end of the electric heating wire 83, and after blowing and heating, it is transmitted to the dehydrated nylon waste silk to realize automatic drying after dehydration of the nylon waste silk;

[0096] While the nylon waste silk is being dried, start the ultraviolet irradiation lamp 9. The ultraviolet rays pass through the transparent window 51 and the pressing roller 66 respectively to fully irradiate and sterilize the nylon waste silk, ensuring the safety and quality of the nylon waste silk after dehydration and recycling.

[0097] The beneficial effects of the nylon waste silk recycling and regenerating granule production device provided in this embodiment:

[0098] By installing a drying mechanism 8 on the installation cover 11, when the nylon waste silk is transmitted between the installation cover 11 and the fixed box 5 after being cleaned, the drying mechanism 8 can blow and dry the dehydrated nylon waste silk, reducing the construction of separate drying equipment, increasing the drying efficiency and production synchronization, and being able to automatically dry after the nylon waste silk is washed.

[0099] Optimization plan:

[0100] Further, refer to Figure 7 , in the nylon waste silk recycling and regenerating granule production device, a detection baffle 52 is fixedly installed in the fixed box 5, a detection contact 611 is fixedly installed on the mounting frame 61, the contact end of the detection contact 611 is matched with the surface of the detection baffle 52, and the output end of the detection contact 611 is electrically connected to the control end of the ultraviolet irradiation lamp 9.

[0101] The detection contact 611 adopts an existing contact switch structure for induction start after contacting the detection baffle 52;

[0102] When the detection contact 611 is not in contact with the detection baffle 52 and the detection contact 611 is not started, the ultraviolet irradiation lamp 9 can be normally switched and controlled;

[0103] When the detection contact 611 is in contact with the detection baffle 52 and the detection contact 611 is started, the ultraviolet irradiation lamp 9 remains in the off state.

[0104] Since the ultraviolet irradiation lamp 9 is installed in the fixed box 5, it is not convenient to quickly identify whether it is turned off when the equipment is shut down. Therefore, it is necessary to safely and reliably turn off the ultraviolet irradiation lamp 9.

[0105] When the telescopic member 7 drives the mounting bracket 61 to contract, the mounting bracket 61 synchronously drives the detection contact 611 to retract. The contact end of the detection contact 611 can contact the detection baffle 52, the detection contact 611 is activated, and the ultraviolet irradiation lamp 9 is turned off, realizing the automatic control of turning off the ultraviolet irradiation lamp 9 when the device is in the shutdown state, preventing the ultraviolet irradiation lamp 9 from being forgotten to be turned off when the device is shut down, and ensuring the stable operation of the device.

[0106] The present invention also provides a production process for recycled polyamide waste silk pellets, comprising the following steps:

[0107] S1, cotton yarn cutting;

[0108] S2, conveyor belt type water washing, conveying the polyamide waste silk to below the water surface through the conveyor belt 2 and the traction shaft 3;
