A heating device for processing polyester composite fabrics

Abstract

This utility model discloses a heating device for processing polyester composite fabric, including a feeding roller, a receiving roller, a heating frame, a pressing frame, and a fixing base. During use, the heating frame is positioned higher than the feeding and receiving rollers, placing the polyester composite fabric and the conveying rollers in the heating frame at different levels. This allows the conveying rollers to support and unfold the polyester composite fabric, keeping it flat during transport. This also allows the heating gas from the steam spray box at the bottom of the heating frame to better contact the unfolded polyester composite fabric, ensuring a good heat-setting effect. A push-flow fan installed at the top of the cleaning air chamber guides the rising airflow downwards, working in conjunction with the inclined air pipes to achieve air circulation and floating within the cleaning air chamber. This further improves the collection of floating dust within the cleaning air chamber, ensuring effective removal of dust from the surface of the polyester composite fabric.

Description

Technical Field

[0001] This utility model relates to the field of heat setting technology for polyester composite fabrics, specifically a heating device for processing polyester composite fabrics. Background Technology

[0002] Polyester is prone to internal stress during textile processing. Heating can cause the molecular chain segments to rearrange, releasing the internal stress and preventing shrinkage or deformation caused by stress release during subsequent use. By heating to above the glass transition temperature, the polyester molecular chain segments gain the ability to move and form a new arrangement. Rapid cooling thereafter can lock in the new structure and improve dimensional stability.

[0003] In the prior art, publication number "CN219486821U" discloses a heating device for processing polyester composite fabrics, relating to the field of fabric production and processing technology. The device includes a frame with several heating rollers evenly installed on its lower side. Fixed guide rollers are installed at each of the four corners of the frame. Rotary frames are rotatably connected to both sides of the frame, and telescopic rods are fixedly installed at the outer ends of the rotating frames. Return springs are sleeved around the lower periphery of the telescopic rods. The polyester fabric heating device of this invention features a structure with synchronously adjustable tensioning or loosening of the upper and lower side pressing belts and heating belts. This structure can straighten and compress the middle fabric, ensuring that the middle fabric and the upper and lower side belts are fully aligned during movement, thereby ensuring uniform and sufficient heating of the fabric. Compared to traditional equipment, this heating device has higher heating efficiency and is easy to adjust and operate.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] In the aforementioned devices and existing technologies, the lack of tension adjustment during the heat setting of polyester composite fabrics results in the polyester composite fabric becoming loose during transport, leading to uneven heating of the fabric surface. Furthermore, the looseness of the fabric makes it prone to wrinkles and the adhesion of impurities and dust. These impurities can affect the polyester composite fabric during the heat setting process, easily causing color differences on its surface. Utility Model Content

[0030] 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.

[0031] Please see Figure 1-5 This utility model provides a technical solution:

[0032] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution:

[0033] A heating device for processing polyester composite fabric includes a feeding roller 1, a taking-up roller 2, a heating frame 3, a pressing and bonding frame 5, and a fixing seat 6. The feeding roller 1 and the taking-up roller 2 are arranged on both sides of the heating frame 3 for releasing and winding the polyester composite fabric. The pressing and bonding frame 5 is installed on one side of the top of the heating frame 3. The fixing seats 6 are symmetrically arranged in two sets, and the two sets of fixing seats 6 are symmetrically installed on the top of the pressing and bonding frame 5.

[0034] A polyester fabric conveying surface cleaning and heat setting unit is provided at the top of the heating frame 3. It is used to perform surface heat setting treatment on polyester fabric and reduce the impact of impurities on the heat setting effect of polyester fabric.

[0035] The polyester fabric conveying surface cleaning and heat setting unit includes a cleaning section 1, which includes a cleaning air chamber 4. The cleaning air chamber 4 is installed on the top of the heating frame 3 near the feeding roller 1. An air box 42 is installed inside the cleaning air chamber 4. An inclined air pipe 41 is connected to one side of the air box 42. Multiple sets of inclined air pipes 41 are arranged at intervals. Multiple sets of inclined air pipes 41 are fixed to the top of the cleaning air chamber 4. A push-flow fan 43 is installed on the top of the cleaning air chamber 4 near the pressing frame 5.

[0036] The polyester fabric conveying surface cleaning and heat setting unit also includes a heating section, which includes a steam spray box 31. The steam spray box 31 is installed at the bottom of the heating frame 3. Multiple sets of conveying rollers 32 are installed at intervals on the surface of the heating frame 3. The surface of the steam spray box 31 is provided with spray holes. An air gap 33 is provided between adjacent conveying rollers 32. The heated gas sprayed from the steam spray box 31 passes through the air gap 33 and contacts the polyester composite fabric.

[0037] In this embodiment, the polyester composite fabric is kept flat during the conveying and transfer process, so that the heating gas sprayed from the steam spray box 31 installed at the bottom of the heating frame 3 can better contact the unfolded polyester composite fabric, thereby achieving effective heating of the polyester composite fabric and ensuring the heat setting effect of the polyester composite fabric.

[0038] Example 2:

[0039] Based on Embodiment 1, this embodiment takes into account that some dust and impurities on the surface of polyester composite fabric cannot be removed by means of gas circulation blowing. In order to avoid this problem affecting the effective heat setting step of polyester composite fabric, this embodiment is provided with a stubborn impurity extrusion and adhesion removal unit on the surface of polyester fabric to avoid the above problem interfering with the heat setting of polyester composite fabric.

[0040] The unit for removing stubborn impurities from the surface of the polyester fabric by squeezing and adhering includes a moving part, which includes a rotating main shaft 61. The rotating main shaft 61 is installed between adjacent fixed seats 6. A reduction motor 63 is installed on the surface of the fixed seat 6. The output end of the reduction motor 63 is fixed to one end of the rotating main shaft 61. A drive gear 62 is sleeved and installed on the surface of the rotating main shaft 61. A movable slide 7 is slidably installed through the surface of the pressing and adhering frame 5. A linear toothed plate 71 is embedded in the surface of the movable slide 7. The linear toothed plate 71 meshes with the drive gear 62.

[0041] The unit for removing stubborn impurities from the surface of the polyester fabric by squeezing and adhering also includes an adhesive part, which includes a positioning frame 8. The positioning frame 8 is installed on one side of the movable slide table 7. An electric rotating shaft 81 is embedded in the surface of the positioning frame 8, and a cleaning guide roller 82 is installed at the rotating end of the electric rotating shaft 81.

[0042] The surface of the cleaning guide roller 82 is provided with an adhesive layer 83.

[0043] In this embodiment, the electric rotating shaft 81 at the bottom of the movable slide 7 drives the cleaning guide roller 82 to apply pressure to guide the surface of the polyester composite fabric. At the same time, the adhesive layer 83 on the surface of the cleaning guide roller 82 can stick and remove dust and impurities attached to the surface of the polyester composite fabric, thereby improving the cleaning effect of the polyester composite fabric surface and ensuring that the polyester composite fabric can undergo an effective heat setting step.

[0044] Working principle: During use, the operator drives the feeding roller 1 and the take-up roller 2 to feed and rewind the polyester composite fabric. To prevent the polyester composite fabric from remaining flat during the heat setting process, the heating frame 3 is set at a height higher than the feeding roller 1 and the take-up roller 2. This makes the polyester composite fabric and the conveying roller 32 in the heating frame 3 at different levels, allowing the conveying roller 32 to support and unfold the polyester composite fabric upwards. This keeps the polyester composite fabric flat during the conveying and transfer process, allowing the heating gas sprayed from the steam spray box 31 at the bottom of the heating frame 3 to better contact the unfolded polyester composite fabric, achieving effective heating of the polyester composite fabric and ensuring the heat setting effect of the polyester composite fabric.

[0045] In the heat setting step of polyester composite fabric, in order to avoid the influence of dust adhering to the surface of polyester composite fabric on the polyester composite fabric, the surface of polyester composite fabric can be circulated by blowing and sucking air through the inclined air pipe 41 and air box 42 installed in the cleaning air chamber 4. The floating dust on the surface of polyester composite fabric will be carried into the air box 42 and filtered by the filter chamber outside the air box 42 during the continuous circulation of air blowing and sucking. At the same time, the push-flow fan 43 installed in the top area of ​​the cleaning air chamber 4 will guide the rising airflow downward, thereby cooperating with the inclined air pipe 41 to realize the circulation and floating of air inside the cleaning air chamber 4, further improving the collection effect of floating dust in the cleaning air chamber 4 and ensuring the removal effect of floating dust on the surface of polyester composite fabric.

[0046] Dust on the surface of polyester composite fabric can be effectively removed by gas circulation, but residual deposits on the surface of polyester composite fabric cannot be removed by gas circulation. In order to ensure the cleaning effect of the polyester composite fabric surface, the rotating main shaft 61 and the drive gear 62 can be rotated by the drive reduction motor 63. The drive gear 62 meshes with the linear tooth plate 71 and the movable slide 7 to slide vertically. When the movable slide 7 approaches the surface of the polyester composite fabric, the electric rotating shaft 81 at the bottom of the movable slide 7 will drive the cleaning guide roller 82 to pressurize and guide the surface of the polyester composite fabric. At the same time, the adhesive layer 83 on the surface of the cleaning guide roller 82 can stick and remove dust and impurities attached to the surface of the polyester composite fabric, improve the cleaning effect of the polyester composite fabric surface, and thus ensure the effective heat setting step of the polyester composite fabric.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
