Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric production, in particular to a drying device for non-woven fabric production. Background Art

[0002] Non-woven fabric, also known as non-woven fabric, needle-punched cotton, needle-punched non-woven fabric, etc., is made by mixing 80% polypropylene, 18% polyethylene, 0.15%-0.3% permethrin and 1.7%-1.85% dispersant, and then the mixture is needle-punched to make non-woven fabric. It can be made into different thickness, feel, hardness, etc. Non-woven fabric is moisture-proof, breathable, flexible, thin, flame retardant, non-toxic and odorless, low price, recyclable, etc.

[0003] During the production process, non-woven fabrics need to be cleaned to remove impurities on their surface. After cleaning, the non-woven fabrics need to be dried by drying equipment.

[0004] After searching, it is found that in a drying device for automobile interior non-woven fabric processing with patent publication number CN220689649U, it is proposed that "through the provision of a slapping rod, when the drying effect of the non-woven fabric needs to be improved, the driving motor can be started to drive the rotating rod to rotate, and then the rotating rod can cause the mounting sleeve to drive the slapping rod to rotate. At this time, the slapping rod can slap the non-woven fabric, thereby improving the drying effect and preventing the non-woven fabric from having a poor drying effect during the drying operation and needing to enter the drying device body for processing again, thereby affecting the work efficiency";

[0005] However, the above scheme still has certain shortcomings in actual use. The drying device does not pre-treat the non-woven fabric when drying the non-woven fabric, resulting in the non-woven fabric still carrying a large amount of moisture before drying. As a result, the drying device takes a long time to dry the non-woven fabric, thereby reducing the drying efficiency. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model discloses a drying device for non-woven fabric production, including a processing platform 1, a top of which is provided with a conveying roller 2, a pretreatment structure 3, a drying structure 4 and a winding structure 5, and the conveying roller 2, the pretreatment structure 3, the drying structure 4 and the winding structure 5 are arranged in sequence from front to back.

[0023] The pretreatment structure 3 includes a mounting frame 301, a vertical rod 304 and a water collection tank 309. The inner wall of the mounting frame 301 is rotatably connected to a double-headed screw 302 via an external motor. The surface of the double-headed screw 302 is threadedly connected to two threaded blocks 303. The movement directions of the two threaded blocks 303 are opposite. A lifting frame 306 is fixedly installed on the side ends of the two threaded blocks 303. The inner wall of the lifting frame 306 is rotatably connected to a rotating shaft 307.

[0024] By setting up the pretreatment structure 3, the double-headed screw 302 on the inner side of the mounting frame 301 is used to drive the two sets of lifting frames 306 to move relative to each other through the threaded block 303, so that the rotating shaft 307 on the inner side of the two sets of lifting frames 306 drives the squeezing pad 308 to perform double squeezing on the top and bottom surfaces of the non-woven fabric, thereby squeezing out the moisture contained in the non-woven fabric, thereby achieving the dehydration of the non-woven fabric, avoiding the situation where the non-woven fabric carries a large amount of moisture before drying, thereby effectively reducing the time spent by the user in drying the non-woven fabric, improving the user experience of the drying device, and improving the drying efficiency.

[0025] The drying structure 4 includes a through-frame 401, the inner walls of which are provided with a drying device body 402 and a heating wire 403, respectively. The drying device body 402 is located above the heating wire 403, a heat-conducting fan 404 is provided at the top of the heating wire 403, and a dust-proof net is provided above the heat-conducting fan 404.

[0026] The working principle of the drying device body 402 has been proposed in CN220689649U, a drying device for processing non-woven fabrics for automobile interior decoration, and will not be described in detail here.

[0027] The winding structure 5 includes a driving frame 501, a resistance frame 502 and a winding shaft 503. The movable end of the driving frame 501 is provided with a notch. One end of the winding shaft 503 is fixedly connected with a square shaft, which is movably plugged into the notch of the movable end of the driving frame 501. The movable end of the resistance frame 502 is provided with a notch, and the other end of the winding shaft 503 is overlapped with the notch of the movable end of the resistance frame 502.

[0028] The driving frame 501 includes a mounting back plate and a brake motor, and the output shaft of the brake motor is provided with a notch, and the square shaft is movably plugged into the notch of the output shaft of the brake motor.

[0029] The abutment frame 502 includes an electric push rod and an abutment plate. A notch is formed at the top of the abutment plate, and the other end of the winding shaft 503 overlaps with the notch at the top of the abutment plate.

[0030] Specifically, a sliding block 305 is fixedly connected to the side end of the threaded block 303 , and the sliding block 305 is slidably connected to the surface of the vertical rod 304 .

[0031] In this embodiment, the slider 305 is used to slide along the surface of the vertical rod 304 along with the threaded block 303, thereby improving the lifting stability of the threaded block 303.

[0032] Specifically, a compression pad 308 is sleeved on the surface of the rotating shaft 307 , and the compression pad 308 is a soft silicone pad.

[0033] In this embodiment, the squeezing pad 308 can form elastic contact between the rotating shaft 307 and the non-woven fabric, so that the rotating shaft 307 is buffered during the squeezing process of the non-woven fabric, thereby preventing the rotating shaft 307 from damaging the non-woven fabric.

[0034] When in use, the nonwoven fabric is first passed through the conveying roller 2, the pretreatment structure 3 and the drying structure 4 in sequence and finally wound on the winding shaft 503, and then the winding structure 5 is started through the control panel to be wound;

[0035] The driving frame 501 drives the non-woven fabric to roll up through the roll-up shaft 503, so that the non-woven fabric starts to move slowly;

[0036] Then, the pretreatment structure 3 is started through the control panel, so that the external motor drives the double-headed screw 302 to rotate, so that the double-headed screw 302 can drive the two threaded blocks 303 to move relative to each other, so that the threaded blocks 303 drive the rotating shaft 307 to move toward the non-woven fabric through the lifting frame 306, so that the two sets of rotating shafts 307 are finally in contact with the non-woven fabric, and with the continuous movement of the non-woven fabric, the rotating shaft 307 drives the squeezing pad 308 to double squeeze the top and bottom surfaces of the non-woven fabric, thereby squeezing out the water contained in the non-woven fabric, and the remaining water will automatically fall into the water collection tank 309 to wait for the staff to recycle;

[0037] Then, the dehydrated non-woven fabric enters the through-rack 401, and then the drying device body 402, the electric heating wire 403 and the heat-conducting blower 404 are started, and the heat generated by the electric heating wire 403 is used to generate heat, and the heat-conducting blower 404 can blow the heat to the bottom surface of the non-woven fabric, and the drying device body 402 can dry the top surface of the non-woven fabric, so that the non-woven fabric is dried on both sides;

[0038] After all the non-woven fabrics are rolled up onto the winding shaft 503, the abutment frame 502 is started to cause the movable end of the abutment frame 502 to descend, thereby releasing the overlapping state between the abutment frame 502 and the winding shaft 503. Subsequently, the winding shaft 503 is pulled outward to cause the square shaft at the end of the winding shaft 503 to disengage from the notch at the movable end of the driving frame 501, thereby pulling the winding shaft 503 out from the movable end of the driving frame 501.

[0039] In summary, the drying device for non-woven fabric production, by setting a pretreatment structure 3, utilizes the double-headed screw 302 on the inner side of the mounting frame 301 to cause the two sets of lifting frames 306 to move relative to each other through the threaded block 303, so that the rotating shaft 307 on the inner side of the two sets of lifting frames 306 drives the squeezing pad 308 to perform double squeezing on the top and bottom surfaces of the non-woven fabric, thereby squeezing out the moisture contained in the non-woven fabric, thereby achieving the dehydration of the non-woven fabric, avoiding the situation where the non-woven fabric carries a large amount of moisture before drying, thereby effectively reducing the time spent by the user in drying the non-woven fabric, improving the user experience of the drying device, and improving the drying efficiency.
