Description

A nonwoven fabric unwinding hot pressing device Technical Field

[0001] This utility model relates to the field of nonwoven fabric production, specifically a nonwoven fabric unwinding hot pressing device. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, is composed of oriented or randomly arranged fibers. It is a new generation of environmentally friendly material with characteristics such as moisture resistance, breathability, flexibility, light weight, non-combustibility, easy decomposition, non-toxicity, non-irritation, rich colors, low price, and recyclability. Non-woven fabric is also called non-woven material, non-woven cloth, or non-woven fabric. It is made by oriented or randomly arranged fibers through friction, cohesion, bonding, or a combination of these methods. The essence lies in "non-woven". Non-woven fabric exists in the form of fibers in the cloth, while woven cloth exists in the form of yarn. This is also a major characteristic that distinguishes non-woven fabric from other cloths. You cannot pull out individual threads in non-woven fabric. In order to improve the production efficiency of non-woven fabric, an unwinding hot pressing device is needed.

[0003] However, current nonwoven fabric unwinding hot pressing devices still have some shortcomings. For example, existing nonwoven fabric processing mostly uses adhesive bonding for lamination, which reduces the durability of nonwoven fabrics. At the same time, most adhesives contain formaldehyde, which can easily affect the health of users, resulting in reduced practicality and efficiency of the unwinding hot pressing device, thus presenting certain usage defects.

[0004] Therefore, there is an urgent need to improve this shortcoming. This utility model is to study and improve the existing structure to provide a non-woven fabric unwinding hot pressing device.

[0006] The purpose of this invention is to provide a nonwoven fabric unwinding and hot pressing device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a nonwoven fabric unwinding and hot pressing device, comprising a main frame and an unwinding assembly. A conveyor belt is provided on the upper side of the main frame, and an unwinding assembly is provided on the left side of the upper end of the main frame. The unwinding assembly includes a receiving frame, a nonwoven fabric roller, a mounting rod, a limiting through hole, a limiting pin, a mounting block, a pneumatic rod, a movable block, and a pressure roller. The nonwoven fabric roller is connected inside the receiving frame, and mounting rods are connected to both ends of the nonwoven fabric roller. A limiting through hole is opened inside the mounting rod, and a limiting pin is connected inside the limiting through hole. An mounting block is provided on the right side of the receiving frame, and a pneumatic rod is provided at the lower end of the mounting block. A movable block is provided at the front end of the pneumatic rod, and a pressure roller is connected inside the movable block. A hot pressing assembly is provided on the right side of the upper end of the main frame.

[0008] Furthermore, there are two mounting rods, and the two mounting rods are symmetrically arranged at both ends of the nonwoven fabric roller with respect to the central axis of the front of the nonwoven fabric roller.

[0009] Furthermore, the internal dimensions of the limiting through hole match the external dimensions of the limiting pin, and the limiting pin is embeddedly connected to the mounting rod through the limiting through hole.

[0010] Furthermore, the pneumatic rod and the movable block are arranged perpendicularly, and the pneumatic rod and the movable block are threadedly connected.

[0011] Furthermore, the hot pressing assembly includes a fixed block, a limiting slide groove, an electric telescopic rod, and a receiving plate. The fixed block has a limiting slide groove in the middle, and an electric telescopic rod is installed on the upper end of the fixed block. The front end of the electric telescopic rod is provided with a receiving plate.

[0012] Furthermore, the hot pressing assembly also includes a limiting slider, a spring damping rod, a mounting back plate, and a heating block.

[0014] This utility model provides a non-woven fabric unwinding and hot pressing device, which has the following beneficial effects:

[0015] 1. This utility model, through the setting of the unwinding assembly, enables the receiving frame to be fixedly installed on both sides of the upper end of the main frame body by fasteners during the use of the nonwoven fabric unwinding hot pressing device. The nonwoven fabric roller is installed inside the upper end of the receiving frame by the mounting rod, and the mounting rod is limited by the limiting pin to prevent the nonwoven fabric roller from shifting position. The mounting block is fixedly installed on the right side of the receiving frame by fasteners. The pneumatic rod operates to drive the movable block to move its position, so that the pressure roller can adjust its height accordingly. This allows the pressure roller to adjust the tension of the nonwoven fabric during use, thereby improving the flexibility and dynamism of the nonwoven fabric unwinding hot pressing device.

[0016] 2. This utility model, through the setting of the hot pressing component, enables the fixing block to be fixedly installed on the upper right side of the main frame body by fasteners when the non-woven fabric unwinding hot pressing device is in use. The operation of the electric telescopic rod drives the receiving plate to move in position. At the same time, the stability of the receiving plate during the movement is increased by the limiting slide groove and the limiting slider. The spring damping rod makes the mounting back plate elastically connected to the receiving plate. At the same time, the heating block set at the lower end of the mounting back plate operates. As the receiving plate moves down, it drives the position of the mounting back plate to move. The non-woven fabric is hot-pressed through the heating block, thereby improving the overall efficiency of the non-woven fabric unwinding hot pressing device. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] As shown in Figures 1 and 2, a nonwoven fabric unwinding and hot-pressing device includes a main frame 1 and an unwinding assembly 3. A conveyor belt 2 is provided on the upper inner side of the main frame 1, and the unwinding assembly 3 is provided on the upper left side of the main frame 1. The unwinding assembly 3 includes a receiving frame 301, a nonwoven fabric roller 302, a mounting rod 303, a limiting through hole 304, a limiting pin 305, a mounting block 306, a pneumatic rod 307, a movable block 308, and a pressing rubber roller 309. The nonwoven fabric roller 302 is connected inside the receiving frame 301, and the mounting rods 303 are connected to both ends of the nonwoven fabric roller 302. An internal limiting through hole 304 is provided, and a limiting pin 305 is connected inside the limiting through hole 304. A mounting block 306 is provided on the right side of the receiving frame 301, and a pneumatic rod 307 is provided at the lower end of the mounting block 306. A movable block 308 is provided at the front end of the pneumatic rod 307, and a pressure roller 309 is connected to the inner side of the movable block 308. There are two mounting rods 303, and the two mounting rods 303 are symmetrically arranged at both ends of the nonwoven fabric roller 302 around the central axis of the front of the nonwoven fabric roller 302. The internal dimensions of the limiting through hole 304 and the external dimensions of the limiting pin 305 are... The limit pins 305 and 308 are fitted together and embedded in the mounting rod 303 through the limit through hole 304. The pneumatic rod 307 and the movable block 308 are vertically distributed and threadedly connected. The receiving frame 301 is fixedly installed on both sides of the upper end of the main frame 1 by fasteners. The non-woven fabric roller 302 is installed inside the upper end of the receiving frame 301 by the mounting rod 303. At the same time, the internal dimensions of the limit through hole 304 inside the mounting rod 303 match the external dimensions of the limit pin 305, so that the mounting rod 303 is limited inside the receiving frame 301. Then, the mounting rod 303 is limited by the limiting pin 305 to prevent the nonwoven fabric roller 302 from shifting position. The mounting block 306 is fixedly installed on the right side of the receiving frame 301 by fasteners, and the pneumatic rod 307 is fixedly installed on the lower end of the mounting block 306 with fasteners. The operation of the pneumatic rod 307 drives the movable block 308 to move, so that the pressure roller 309 can adjust its height accordingly. This allows the pressure roller 309 to adjust the tension of the nonwoven fabric during use, thereby improving the flexibility and dynamism of the nonwoven fabric unwinding hot pressing device.

[0023] As shown in Figures 1 to 3, a hot pressing assembly 4 is provided on the upper right side of the main frame 1. The hot pressing assembly 4 includes a fixing block 401, a limiting slide groove 402, an electric telescopic rod 403, and a receiving plate 404. The fixing block 401 has a limiting slide groove 402 in the middle, and the electric telescopic rod 403 is installed on the upper end of the fixing block 401. The receiving plate 404 is provided at the front end of the electric telescopic rod 403. The hot pressing assembly 4 also includes a limiting slider 405 and a spring damping rod 4. 06. Install the back plate 407 and heating block 408. Simultaneously, limit sliders 405 are added to both sides of the outer surface of the receiving plate 404. A spring damping rod 406 is installed at the lower end of the receiving plate 404, and the front end of the spring damping rod 406 is provided with the mounting back plate 407. The heating block 408 is installed at the lower end of the mounting back plate 407. The internal dimensions of the limit groove 402 match the external dimensions of the limit slider 405, and the limit slider 405 is connected to the fixed... Block 401 is slidably connected and fixedly installed on the upper right side of the main frame 1 by fasteners. The electric telescopic rod 403 is also fixedly installed on the upper end of the fixed block 401 with fasteners. The operation of the electric telescopic rod 403 drives the receiving plate 404 to move. At the same time, the external dimensions of the limiting sliders 405 set at both ends of the receiving plate 404 match the internal dimensions of the limiting grooves 402 opened inside the fixed block 401. Thus, the limiting grooves 402 and the limiting sliders 405 increase the stability of the receiving plate 404 during movement. The spring damping rod 406 makes the mounting back plate 407 elastically connected to the receiving plate 404. At the same time, the heating block 408 set at the lower end of the mounting back plate 407 operates. As the receiving plate 404 moves down, it drives the position of the mounting back plate 407 to move. The heating block 408 performs hot pressing processing on the non-woven fabric, improving the overall efficiency of the non-woven fabric unwinding hot pressing device.

[0024] In summary, this nonwoven fabric unwinding and hot pressing device first uses fasteners to limit the installation of the conveyor belt 2 inside the upper part of the main frame 1, and uses the conveyor belt 2 to transport the items to be processed. Fasteners are also used to fix the receiving frame 301 to both sides of the upper part of the main frame 1. The nonwoven fabric roller 302 is then installed inside the receiving frame 301 via the mounting rod 303. Simultaneously, the internal dimensions of the limiting through-hole 304 inside the mounting rod 303 match the external dimensions of the limiting pin 305. Thus, after the mounting rod 303 is limited inside the receiving frame 301, the limiting pin 305 limits the mounting rod 303, thereby preventing the nonwoven fabric roller 302 from shifting position. Fasteners are used to fix the mounting block 306 to the right side of the receiving frame 301, and fasteners are used to fix the pneumatic rod 307 to the lower end of the mounting block 306. The pneumatic rod 307 operates to drive the... The moving block 308 moves, causing the pressure roller 309 to adjust its height accordingly. This allows the pressure roller 309 to adjust the tension of the nonwoven fabric during use, thereby improving the flexibility and dynamism of the nonwoven fabric unwinding hot pressing device. Next, the fixing block 401 is fixedly installed on the upper right side of the main frame 1 using fasteners, and the electric telescopic rod 403 is fixedly installed on the upper end of the fixing block 401 using fasteners. The operation of the electric telescopic rod 403 drives the receiving plate 404 to move. At the same time, the external dimensions of the limiting sliders 405 set at both ends of the receiving plate 404 match the internal dimensions of the limiting grooves 402 opened inside the fixing block 401. This increases the stability of the receiving plate 404 during movement through the limiting grooves 402 and the limiting sliders 405. The spring damping rod 406 is used to mount the back plate 407. The device is elastically connected to the receiving plate 404 and simultaneously installed with the heating block 408 at the lower end of the back plate 407. As the receiving plate 404 moves downward, the position of the back plate 407 moves, and the heating block 408 performs hot pressing on the nonwoven fabric, thereby improving the overall efficiency of the nonwoven fabric unwinding hot pressing device.
