Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing technology, and in particular to a nonwoven fabric drying equipment. Background Technology

[0002] Drying is a crucial step in the production of nonwoven fabrics. Nonwoven fabric drying equipment is a specialized device used to remove surface and internal moisture from wet nonwoven fabrics during production, and it is one of the core pieces of equipment in nonwoven fabric processing. Its core function is to evaporate or absorb moisture from the nonwoven fabric through controlled heating, airflow circulation, or physical adsorption, ensuring that the nonwoven fabric reaches the required dryness for subsequent processing or finished product, while maintaining its physical properties (such as strength, softness, and dimensional stability) without damage.

[0003] Traditional nonwoven fabric drying equipment typically feeds wet nonwoven fabric directly into a drying chamber for heating and drying. Since the wet nonwoven fabric has not undergone effective pretreatment before entering the drying chamber, the moisture distribution on its surface is uneven, resulting in local over-drying or under-drying during the drying process, leading to poor product quality after drying.

[0004] Therefore, there is an urgent need for a nonwoven fabric drying equipment that can pre-treat nonwoven fabrics before drying, thereby improving the drying effect of nonwoven fabrics. Utility Model Content

[0005] Therefore, to address the aforementioned problems, this utility model proposes a nonwoven fabric drying device. It solves the technical problem that when wet nonwoven fabrics enter the drying chamber without effective pretreatment, the uneven distribution of moisture on the surface leads to localized over-drying or under-drying during the drying process, resulting in poor product quality after drying.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: It includes a base, a drying chamber body mounted on the upper surface of the base, an inlet end on the right side of the drying chamber body, a pretreatment structure corresponding to the inlet end mounted on the right side of the drying chamber body, an output end on the left side of the drying chamber body with a corresponding output roller, and the pretreatment structure including mounting plates symmetrically mounted on the right side of the drying chamber body and located on both sides of the inlet end. A rectangular groove is formed on the surface of the mounting plate, an adjusting screw is provided within the rectangular groove, the top of the adjusting screw extends outside the rectangular groove, a connecting rod is provided between the two mounting plates, the left and right ends of the connecting rod pass through the rectangular groove and are fixed with nuts, a roller sleeve is fitted on the surface of the connecting rod, a rotatable first mounting sleeve is fitted on the left and right sides of the connecting rod, and a pressure rod is located in front of the roller sleeve and connected to the first mounting sleeve at both ends.

[0007] A movable roller is provided between the two mounting plates and below the roller sleeve. The movable roller is fitted with mating bushings at both ends. The left end of the movable roller passes through the mounting plate and is connected to a drive motor. An adjustable and rotatable second mounting sleeve is fitted on the surface of the mating bushing. An mounting rod is connected to the front surface of the second mounting sleeve. A moisture-absorbing plate is installed between the two mounting rods. A support roller is installed on the front surface of the moisture-absorbing plate. Limiting sleeves are provided at both ends of the support roller, and the limiting sleeves are fitted with the mounting rods.

[0008] Furthermore, it also includes a suction pump connected to the moisture-absorbing plate.

[0009] Furthermore, the moisture-absorbing plate is connected to the suction pump via a pipe, and the moisture-absorbing plate has a hollow internal structure and a permeation plate installed on its surface.

[0010] A snap-fit ​​plate is provided on one side where the moisture-absorbing plate meets the support roller, and a snap-fit ​​groove is provided on the support roller at the position corresponding to the snap-fit ​​plate.

[0011] Furthermore, a flexible permeation layer is laid on the surface of the permeation plate.

[0012] Furthermore, one end of the adjusting screw located inside the rectangular slot is connected to the connecting rod, and the other end passes through the mounting plate and is exposed to the air. A nut is fitted on the upper part of the adjusting screw, and the position of the adjusting screw inside the rectangular slot is fixed by rotating the nut.

[0013] Furthermore, the movable roller includes a mounting sleeve and a sleeve rod connected to a drive motor, and the mating bushing is fitted onto the sleeve rod.

[0014] Furthermore, a splined shaft is provided at the end of the mounting rod away from the second mounting sleeve, and the splined shaft fits into the corresponding spline groove inside the limiting sleeve rod in a tight fit manner.

[0015] Furthermore, the limiting sleeve includes a connecting rod and a spline sleeve that engages with the spline shaft, and a fixing sleeve is provided at the position where the limiting sleeve connects to the support roller.

[0016] Furthermore, the inlet end is flush with the pretreatment structure. The inlet end is a rectangular frame structure, and the upper and lower walls inside the rectangular frame are arc-shaped protrusions to reduce the friction when the non-woven fabric enters the drying box body, avoid damage to the non-woven fabric, and also play a certain guiding role, so that the non-woven fabric can enter the drying box more smoothly.

[0017] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0018] This nonwoven fabric drying equipment features a pre-treatment structure flush with the inlet. The rotation of the pressure rod and support rollers optimizes the contact distance between them and the nonwoven fabric. Under the pressure of the pressure rod, the nonwoven fabric contacts the surface of the moisture-absorbing plate. Combined with the permeation layer on the moisture-absorbing plate and the suction pump, moisture is absorbed from the surface of the nonwoven fabric. This synergistic arrangement of the above structures effectively provides preliminary dehumidification for the nonwoven fabric before it enters the drying chamber, thereby improving drying efficiency and quality.

[0019] In practical work, the height of the roller sleeve can be adjusted by using the adjusting screw, which can be set according to the thickness of the nonwoven fabric being dried, allowing for flexible adjustment of the nonwoven fabric pretreatment. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0028] refer to Figure 1 - Figure 6This embodiment provides a nonwoven fabric drying device, including a base 1, a drying chamber body 2 mounted on the upper surface of the base 1, an inlet end 3 on the right side of the drying chamber body 2, a pretreatment structure 4 corresponding to the inlet end 3 mounted on the right side of the drying chamber body 2, and an output end 5 on the left side of the drying chamber body 2. The pretreatment structure 4 includes mounting plates 401 symmetrically mounted on the right side of the drying chamber body 2 and located on both sides of the inlet end 3. Rectangular grooves 401a are formed on the surface of the mounting plates 401a. An adjusting screw 402 is provided inside 1a. The top end of the adjusting screw 402 extends to the outside of the rectangular groove frame 401a. A connecting rod 403 is provided between the two mounting plates 401. The left and right ends of the connecting rod 403 pass through the rectangular groove frame 401a respectively and are fixed with nuts 405. A roller sleeve 404 is fitted on the surface of the connecting rod 403. A first mounting sleeve 406 that can rotate is fitted on the left and right sides of the connecting rod 403 respectively. A pressure rod 407 is located in front of the roller sleeve 404 and its left and right ends are connected to the first mounting sleeve 406 respectively.

[0029] A movable roller 408 is provided between two mounting plates 401 and below the roller sleeve 404. The movable roller 408 is fitted with mating bushings 409 at both ends. The left end of the movable roller 408 passes through the mounting plate 401 and is connected to a drive motor 4010. An adjustable and rotatable second mounting sleeve 4011 is fitted on the surface of the mating bushing 409. A mounting rod 4012 is connected to the front surface of the second mounting sleeve 4011. A moisture-absorbing plate 4013 is installed between the two mounting rods 4012. A support roller 4016 is installed on the front surface of the moisture-absorbing plate 4013. Limiting sleeves 4017 are provided at both ends of the support roller 4016, and the limiting sleeves 4017 are fitted with the mounting rods 4012. A suction pump 6 connected to the moisture-absorbing plate 4013 is also included.

[0030] This equipment is mainly used to perform preliminary dehumidification treatment on non-woven fabrics before they enter the drying chamber by using the pretreatment structure 4. Through the coordinated action of components such as the pressure rod 407, support roller 4016, and moisture-absorbing plate 4013, the non-woven fabrics are pre-treated to improve drying efficiency and quality.

[0031] Specifically, one end of the adjusting screw 402 located inside the rectangular groove 401a is connected to the connecting rod 403, and the other end passes through the mounting plate 401 and is exposed to the air. A nut is fitted on the upper part of the adjusting screw 402. By rotating the nut, the position of the adjusting screw 402 inside the rectangular groove 401a is fixed, thereby adjusting the height of the connecting rod 403 to meet the pretreatment requirements of nonwoven fabrics of different thicknesses.

[0032] The moisture-absorbing plate 4013 is connected to the suction pump 6 via a pipe 4015. The moisture-absorbing plate 4013 has a hollow internal structure and a permeation plate installed on its surface. Since the suction pump 6 can generate negative pressure, it accelerates the airflow around the moisture-absorbing plate, allowing the moisture-absorbing plate 4013 to absorb moisture from the non-woven fabric more quickly, further improving the dehumidification effect in the pretreatment stage. At the same time, since the permeation plate has a flexible permeation layer on its surface, it allows moisture to penetrate into the interior of the moisture-absorbing plate 4013 more easily, enhancing the moisture absorption capacity of the moisture-absorbing plate. A snap-fit ​​plate 4014 is provided on one side where the moisture-absorbing plate 4013 connects with the support roller 4016. A snap-fit ​​groove 4018 is opened at the corresponding position of the support roller 4016 and the snap-fit ​​plate 4014. During the operation of the equipment, the moisture-absorbing plate 4013 can be prevented from loosening due to vibration of the equipment or external force, ensuring that the moisture-absorbing plate 4013 is always in the correct working position.

[0033] During operation, the movable roller 408, including a mounting sleeve and a sleeve rod connected to the drive motor 4010 (a geared motor), is connected to the sleeve rod of the movable roller 408 via a coupling to achieve rotational propulsion of the nonwoven fabric. Simultaneously, the bushing 409 engages with the sleeve rod. A spline shaft is located at the end of the mounting rod 4012 furthest from the second mounting sleeve 4011. The spline shaft engages tightly with the corresponding spline groove within the limiting sleeve rod 4017. The limiting sleeve rod 4017 includes a connecting rod and a spline sleeve that engages with the spline shaft. A fixed sleeve is located at the connection point between the limiting sleeve rod 4017 and the support roller 4016. The connection between the spline shaft and the spline sleeve enables both torque transmission and angle adjustment, allowing for angular adjustment between the limiting sleeve rod 4017 and the second mounting sleeve 4011 according to actual working conditions.

[0034] Furthermore, the inlet end 3 is flush with the pretreatment structure 4. The inlet end 3 is a rectangular frame structure, and the upper and lower walls inside the rectangular frame are arc-shaped protrusions to reduce the friction when the non-woven fabric enters the drying box body, avoid damage to the non-woven fabric, and also play a certain guiding role, so that the non-woven fabric can enter the drying box more smoothly.

[0035] The working method of this utility model is as follows: Before the equipment starts running, according to the actual non-woven fabric drying situation and the thickness of the non-woven fabric, the height of the roller sleeve 404 is adjusted by adjusting the screw 402 and the nut. After adjusting to a suitable position, the distance between the pressure rod 407 and the moisture absorption plate 4013 is adjusted using the first mounting sleeve 406 connected to the pressure rod 407, and then the upward (downward) angle of the support roller 4016 is adjusted by the second mounting sleeve 4011 until the support roller 4016 is adjusted to a distance from the pressure rod 407. After reaching a suitable angle, the nonwoven fabric at the input end bypasses the support roller 4016 and rests on its surface, extending downwards along the moisture-absorbing plate 4013 connected to the support roller 4016. The upper surface of the nonwoven fabric, in conjunction with the contact of the pressing rod 407, passes through the gap between the roller sleeve 404 and the movable rod 408. Since the end of the movable rod 408 is connected to the drive motor 4010, the movable rod 408, under the action of rotation, can assist the nonwoven fabric in entering the drying chamber body 2. After passing through the roller sleeve 404 and the movable rod 408, the nonwoven fabric passes through the entry end 3 and extends into the interior of the drying chamber body 2.

[0036] With the above-mentioned components, before the non-woven fabric extends into the drying chamber body 2, the support roller 4016 and the moisture-absorbing plate 4013 work together to squeeze and absorb excess moisture adhering to the surface of the non-woven fabric. A permeable layer is laid on the upper surface of the moisture-absorbing plate 4013, which can improve the moisture absorption treatment of the non-woven fabric.

[0037] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
