Description

Technical Field

[0001] This utility model relates to the field of fabric production technology, specifically to an energy-saving hot pressing device for knitted fabric production. Background Technology

This invention is ingeniously designed, maintaining the hot pressing effect of the hot pressing plate without affecting its normal pressing state, significantly improving the stability of the hot pressing and preserving the hot pressing effect.

[0003] However, during the use of the above-mentioned equipment, due to the setting of its internal hot pressing device, the traditional hot pressing relies on the hot pressing plate to directly heat the fabric, which can easily lead to uneven heating of the fabric, resulting in local overheating or underheating, and increasing energy waste. Therefore, we propose a more convenient and practical hot pressing device to meet the usage requirements. Utility Model Content

[0004] The purpose of this invention is to provide an energy-saving hot pressing device for knitted fabric production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving hot pressing device for knitted fabric production, comprising a base, a preheating mechanism on one side of the top of the base, and a hot pressing mechanism on the other side. The preheating mechanism includes a heating chamber with multiple equidistant heat-conducting rods fixedly connected to the inner wall of one side, heating coils installed on the outer walls of the heat-conducting rods, a flow equalization plate fixedly connected to the top of the heating chamber, and multiple equidistant connecting shafts rotatably connected to one side of the top of the heating chamber, with conveying rollers fixedly connected to the outer walls of the connecting shafts.

[0006] Furthermore, a first bevel gear is fixedly connected to one end of the connecting shaft, and a fixing block is fixedly connected to one side of the heating box.

[0007] Furthermore, a through hole is provided on one side of the fixing block, and a rotating rod is rotatably connected inside the through hole.

[0008] Furthermore, the heating box has through holes on both sides, and a connecting pipe is fixedly connected inside the through holes. A fan is installed on the inner wall of one end of the connecting pipe, and a ventilation box is fixedly connected to the other end.

[0009] Furthermore, the hot pressing mechanism includes an L-shaped fixing frame, a buffer block is fixedly connected to the bottom of the fixing frame, a shelf is fixedly connected to one end of the buffer block, and a base plate is fixedly connected to the top of the shelf.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This energy-saving hot-pressing device for knitted fabric production, through the setup of a preheating mechanism and a hot-pressing mechanism, allows the knitted fabric to enter the heating chamber from the feed end during operation. First, the motor on the fixed block drives the rotating rod to rotate, which in turn drives the connecting shaft and the conveying roller to rotate, thus conveying the knitted fabric forward. Simultaneously, the heat-conducting rod inside the heating chamber heats up through the heating coil, and the heat is evenly transferred to the surface of the knitted fabric through the flow equalization plate. During this process, the fan starts, and hot air is transferred to the surface of the knitted fabric through the connecting pipe and the ventilation box. This device can achieve uniform heating of the knitted fabric, avoid local overheating or underheating, reduce energy waste, and is highly practical and suitable for widespread application.

[0018] 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.

[0019] In the fabric production process, hot pressing equipment is required. The hot pressing equipment provided by this utility model is specifically designed for hot pressing operations on knitted fabrics during fabric production. During the hot pressing operation using this equipment, the temperature inside the heating chamber 201 must be strictly controlled during preheating to avoid uneven preheating of the fabric due to excessively high or low temperatures. During the hot pressing operation, the temperature of the hot pressing plate 306 should be adjusted according to the material and thickness of the fabric to ensure optimal hot pressing results. During the fabric conveying process, the conveying speed must be kept stable to avoid the fabric remaining in the preheating area for too long or too short a time, which would affect the preheating effect. Simultaneously, attention should be paid to adjusting the position of the fabric during the conveying process to ensure uniform heating.

[0020] like Figures 1-3 As shown, this utility model provides a technical solution: an energy-saving hot pressing device for knitted fabric production, including a base 1, a preheating mechanism 2 on one side of the top of the base 1, and a hot pressing mechanism 3 on the other side. The preheating mechanism 2 includes a heating box 201 with multiple equidistant heat-conducting rods 202 fixedly connected to the inner wall of one side, and heating coils 203 installed on the outer wall of the heat-conducting rods 202. A flow equalization plate 204 is fixedly connected to the top of the heating box 201, and multiple equidistant connecting shafts 205 are rotatably connected to one side of the top of the heating box 201. A conveying roller 206 is fixedly connected to the outer wall of the connecting shaft 205.

[0021] like Figure 2 As shown, a first bevel gear 207 is fixedly connected to one end of the connecting shaft 205, a fixing block 208 is fixedly connected to one side of the heating box 201, a through hole is opened on one side of the fixing block 208, a rotating rod 209 is rotatably connected in the through hole, a second bevel gear 210 is fixedly connected to the outer wall of the rotating rod 209, the teeth of the second bevel gear 210 and the first bevel gear 207 mesh with each other, through holes are opened on both sides of the heating box 201, a connecting pipe 211 is fixedly connected in the through hole, a fan 212 is installed on the inner wall of one end of the connecting pipe 211, and a ventilation box 213 is fixedly connected to the other end.

[0022] It should be noted that during use, the knitted fabric enters the heating chamber 201 from the feed end. First, the motor on the fixed block 208 drives the rotating rod 209 to rotate, which in turn drives the second bevel gear 210 to rotate, causing the connecting shaft 205 and the conveying roller 206 to rotate and convey the knitted fabric forward. At the same time, the heat-conducting rod 202 in the heating chamber 201 is heated by the heating coil 203. The heat is evenly transferred to the surface of the knitted fabric through the flow equalization plate 204. During this process, the fan 212 is started, and the hot air is transferred to the surface of the knitted fabric through the connecting pipe 211 and the ventilation box 213. The flow equalization plate 204 makes the hot airflow distribution more even, further improving the preheating effect and shortening the preheating time.

[0023] like Figure 3 As shown, the hot pressing mechanism 3 includes an L-shaped fixed frame 301. A buffer block 302 is fixedly connected to the bottom of the fixed frame 301. A shelf 303 is fixedly connected to one end of the buffer block 302. A base plate 304 is fixedly connected to the top of the shelf 303. Cylinders 305 are installed on both sides of the inner wall of the top of the fixed frame 301. A hot pressing plate 306 is fixedly connected to the output end of the cylinder 305.

[0024] It should be noted that during use, the preheated knitted fabric is fed into the hot pressing mechanism 3 by the conveyor roller 206. It first falls onto the placement plate 303, and at the same time, the cylinder 305 drives the hot pressing plate 306 to press down, applying uniform pressure to the knitted fabric. The buffer block 302 at the bottom can absorb the impact force and prevent the fabric from changing due to sudden pressure changes. At the same time, the pressing is completed by combining the residual heat from the preheating. After the pressing is completed, the cylinder 305 resets, and the finished product is conveyed to the next process from the discharge end. The hot pressing mechanism 3 can directly contact the knitted fabric. Combined with the heat from the preheating mechanism 2, it reduces the need for secondary heating and reduces energy waste.

[0025] During operation, the knitted fabric enters the heating chamber 201 from the feed end. First, the motor on the fixed block 208 drives the rotating rod 209 to rotate, which in turn drives the second bevel gear 210 to rotate, causing the connecting shaft 205 and the conveying roller 206 to rotate and convey the knitted fabric forward. At the same time, the heat-conducting rod 202 in the heating chamber 201 heats up through the heating coil 203, and the heat is evenly transferred to the surface of the knitted fabric through the flow equalization plate 204. During this process, the fan 212 starts, and the hot air is transferred to the needle through the connecting pipe 211 and the ventilation box 213. On the fabric surface, the preheated knitted fabric is fed into the hot pressing mechanism 3 by the conveying roller 206. It first falls onto the placement plate 303, and at the same time, the cylinder 305 drives the hot pressing plate 306 to press down, applying uniform pressure to the knitted fabric. The buffer block 302 at the bottom can absorb the impact force and prevent the fabric from changing due to sudden pressure changes. At the same time, the residual heat is used to complete the pressing. After pressing, the cylinder 305 is reset, and the finished product is conveyed to the next process from the discharge end. This device can achieve uniform heating of the knitted fabric, avoid local overheating or underheating, and reduce energy waste.

[0026] 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 embodiments and their equivalents.
