Description

Technical Field

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

[0002] Non-woven fabric, also known as non-woven cloth, needle-punched cotton, needle-punched non-woven fabric, etc., is made of polyester fiber and polyester fiber material. It is made through needle punching process and can be made in different thicknesses, feel, hardness, etc. In order to ensure the flatness of the non-woven fabric surface, a flattening machine is needed to flatten the non-woven fabric during processing.

[0003] A nonwoven fabric processing flattening machine with a correction function, disclosed in CN220846699U, includes a main frame. A motor is mounted on one side of the main frame via a support, and a take-up roller is fixedly connected to the output end of the motor. Through the coordinated use of a PLC controller, an air vent, and two evaporation components, a high-temperature softening function can be achieved. Furthermore, the use of the two evaporation components and the PLC controller avoids the need for machine shutdown for water filling and allows for pre-heating of the water, ensuring the continuous operation of the nonwoven fabric processing flattening machine, improving its working efficiency, and thus increasing the production progress of nonwoven fabric processing. Currently, most flattening machines soften only the lower surface of the nonwoven fabric with high-temperature steam through the air vent. However, due to the high conveying speed of the nonwoven fabric, uneven softening of the surface can easily occur, affecting the overall flattening effect. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that the nonwoven fabric is easily softened unevenly due to the fast conveying speed, which affects the overall flattening effect. The invention provides a nonwoven fabric processing flattening machine that can spray steam evenly from both the top and bottom surfaces of the nonwoven fabric. This double-sided steam softening design avoids the limitation of traditional methods that only soften the bottom surface.

[0005] To achieve the above objectives, this utility model provides a non-woven fabric processing flattening machine, including a mounting frame, a protective frame connected to the mounting frame, a conveying roller and a flattening roller arranged inside the protective frame, an evaporation component arranged below the mounting frame, and a softening component connected above the evaporation component.

[0006] The softening assembly includes an upper softening tube and a lower softening tube, both of which are connected to the evaporation assembly via flexible hoses. Both the upper and lower softening tubes are equipped with multiple jet pipes.

[0007] As a further description of the above technical solution: the upper softening tube is connected to the protective frame via a first electric lifting rod, and the lower softening tube is connected to the protective frame via a second electric lifting rod.

[0008] As a further description of the above technical solution: a feeding roller is provided on one side of the protective frame, a winding assembly is provided on the other side of the protective frame, a control box is provided on one side of the evaporation assembly, and a control panel is provided on the mounting frame.

[0009] As a further description of the above technical solution: the evaporation assembly includes a box, and two water storage chambers are provided inside the box. A heater is installed at the bottom of each water storage chamber. A water level detector is installed on one side of the inner wall of each water storage chamber. A gas collecting hopper is provided above each water storage chamber. The gas collecting hopper is connected to the gas outlet pipe through a connecting pipe.

[0011] As a further description of the above technical solution: the winding assembly includes a support frame, on which a first winding frame and a second winding frame are detachably connected, with the first winding frame located above the second winding frame.

[0012] As a further description of the above technical solution: a third electric lifting rod is provided inside the protective frame, and a pressure roller is connected below the third electric lifting rod.

[0013] As a further description of the above technical solution: a transparent observation frame is provided on one side of the protective frame.

[0014] The above technical solution has the following advantages or beneficial effects:

[0015] This invention features an upper and lower softening pipe, each equipped with multiple jet nozzles. Steam is evenly sprayed from both the upper and lower surfaces of the nonwoven fabric. This double-sided steam softening design avoids the limitations of traditional methods that only soften the lower surface, improving the uniformity of softening on the nonwoven fabric surface and thus enhancing the overall flattening effect. Through the optimized double-sided softening mechanism and uniform steam distribution, the nonwoven fabric is ensured to soften evenly under high-speed conveying, avoiding downtime and quality fluctuations during production. This significantly improves the operating efficiency and processing quality of the production line. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be noted that the terms "vertical", "up", "down", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] like Figure 1-4As shown, the nonwoven fabric processing flattening machine of this utility model includes a mounting frame 1, a protective frame 2 connected to the mounting frame 1, a conveying roller 3 and a flattening roller 4 arranged inside the protective frame 2, an evaporation component 5 arranged below the mounting frame 1, and a softening component 6 connected above the evaporation component 5; the softening component 6 includes an upper softening pipe 61 and a lower softening pipe 62, both of which are connected to the evaporation component 5 through a hose 63, and both the upper softening pipe 61 and the lower softening pipe 62 are provided with multiple air jet pipes 64.

[0026] In the technical solution of this utility model, the high-temperature steam generated by the evaporation component 5 is ejected through the jet pipe of the softening component 6 to uniformly soften the surface of the nonwoven fabric. After being softened by steam, the nonwoven fabric is conveyed by the conveying roller 3 and then pressed by the flattening roller 4 to achieve a uniform flattening effect on the surface of the nonwoven fabric. By setting an upper softening pipe 61 and a lower softening pipe 62, and setting multiple jet pipes 64 on each softening pipe, steam can be uniformly ejected from both the upper and lower surfaces of the nonwoven fabric. This double-sided steam softening design avoids the limitation of traditional methods that only soften the lower surface, helps to improve the uniformity of the softening of the nonwoven fabric surface, thereby improving the overall flattening effect. Through the optimized double-sided softening mechanism and uniform steam distribution, it is ensured that the nonwoven fabric can still be uniformly softened under high-speed conveying, avoiding downtime and quality fluctuations in production. This greatly improves the operating efficiency and processing quality of the production line.

[0027] Specifically, the upper softening tube 61 is connected to the protective frame 2 via the first electric lifting rod 65, and the lower softening tube 62 is connected to the protective frame 2 via the second electric lifting rod 66. The positions of the upper softening tube 61 and the lower softening tube 62 can be adjusted via the first electric lifting rod 65 and the second electric lifting rod 66, which facilitates the adjustment of the position of the air jet tube 64, improves the softening effect, and facilitates the processing of nonwoven fabrics of different thicknesses or properties.

[0028] Among them, a transparent observation frame 13 is set on one side of the protective frame 2, which makes it easy for operators to observe the processing process and monitor the status of the non-woven fabric in real time.

[0029] like Figure 1 and Figure 2 As shown, a feeding roller 7 is provided on one side of the protective frame 2, and a winding assembly 8 is provided on the other side of the protective frame 2. A control box 9 is provided on one side of the evaporation assembly 5, and a control panel 10 is provided on the mounting frame 1. The feeding roller 7 is responsible for feeding the non-woven fabric into the flattening machine, and the winding assembly 8 is responsible for rolling up the processed non-woven fabric. The operation of the device can be controlled by the control box 9 and the control panel 10.

[0030] like Figure 1 and Figure 4As shown, the evaporation assembly 5 includes a housing 51, inside which are two water storage chambers 52. A heater 53 is installed at the bottom of each water storage chamber 52, and a water level detector 54 is installed on one side of the inner wall of each water storage chamber 52. A gas collecting hopper 55 is installed above each water storage chamber 52, and the gas collecting hopper 55 is connected to an outlet pipe 57 via a connecting pipe 56. The housing 51 contains two water storage chambers 52, each with a heater 53 at the bottom. Water is heated to a high temperature to generate steam. The water level detector 54 on the side wall of each water storage chamber ensures an appropriate water level and prevents equipment malfunction due to low water levels. The gas collecting hopper 55 above the water storage chambers is connected to the outlet pipe 57 via a connecting pipe 56, guiding the steam to the softening assembly. This ensures the continuous operation of the nonwoven fabric processing flattening machine, improves its efficiency, and ultimately increases the production progress of the nonwoven fabric processing.

[0031] The steam outlet pipe 57 is connected to the softening component 6 at the top, and each water storage chamber 52 is connected to a water filling pipe 58 at the top. A control valve 59 is installed on the connecting pipe 56, and an alarm 510 is installed on the housing 51. The control valve 59 is installed on the connecting pipe 56, and the user can adjust the steam flow rate to meet different production needs. With the alarm 510, when the system water level detector 54 detects that the water level is too low, an alarm can be issued in time.

[0032] like Figure 1 and Figure 2 As shown, the winding assembly 8 includes a support frame 81, on which a first winding frame 82 and a second winding frame 83 are detachably connected. The first winding frame 82 is located above the second winding frame 83. By setting two winding frames, the first winding frame 82 and the second winding frame 83, it is convenient to manage and replace the winding shaft, and continuous winding of nonwoven fabric can be achieved, thus speeding up the replacement efficiency.

[0033] like Figure 1 and Figure 2 As shown, a third electric lifting rod 11 is provided inside the protective frame 2, and a pressing roller 12 is connected below the third electric lifting rod 11; the height of the pressing roller 12 can be adjusted by the third electric lifting rod 11, which can press the non-woven fabric during the processing to ensure uniform softening.

[0034] The third electric lifting rod 11 and the pressing roller 12 are both provided in twos, with the two pressing rollers 12 located on both sides of the softening component 6.

[0035] Working principle: High-temperature steam generated by the evaporation component 5 is ejected through the jet pipe of the softening component 6 to uniformly soften the surface of the nonwoven fabric. After being softened by steam, the nonwoven fabric is conveyed by the conveying roller 3 and then pressed by the flattening roller 4 to achieve a uniform flattening effect on the surface of the nonwoven fabric. By setting up an upper softening pipe 61 and a lower softening pipe 62, and setting multiple jet pipes 64 on each softening pipe, steam can be uniformly sprayed from both the upper and lower surfaces of the nonwoven fabric. This double-sided steam softening design avoids the limitation of traditional methods that only soften the lower surface, helps to improve the uniformity of the softening of the nonwoven fabric surface, thereby improving the overall flattening effect. Through the optimized double-sided softening mechanism and uniform steam distribution, it is ensured that the nonwoven fabric can still be uniformly softened under high-speed conveying, avoiding downtime and quality fluctuations in production. This greatly improves the operating efficiency and processing quality of the production line.
