Description
Technical Field
[0001] The utility model relates to the field of knitting machinery, in particular to an anti-condensation device applied to a circular knitting machine. Background Art
[0002] At present, most circular knitting machines are composed of a yarn feeding mechanism, a looping mechanism, a pulling and winding mechanism, a transmission mechanism and an auxiliary mechanism, among which the looping mechanism is a mechanism that bends the yarn into a coil and makes the coils interlocked to form an annular tubular knitted fabric. The looping mechanism is in a horizontally arranged ring shape as a whole, and the annular tubular knitted fabric is formed vertically on the inner side of the looping mechanism. Since a large amount of heat will be generated due to friction during the operation of the looping mechanism, and most of the moving parts on the looping mechanism are located on its inner side, a large amount of heat will act on the inner side of the annular tubular knitted fabric, which will easily lead to a relatively high air temperature inside the annular tubular knitted fabric. When the outside air temperature is low, this will easily lead to a large temperature difference between the inside and outside of the annular tubular knitted fabric. And when the annular tubular knitted fabric is output from the looping mechanism, it will be directly affected by the cold air, so that the temperature of the annular tubular knitted fabric will drop. When the hot air inside the circular tubular knitted fabric meets the circular tubular knitted fabric with a low temperature, it is easy to condense on the circular tubular knitted fabric to form water droplets, which can easily lead to the circular tubular knitted fabric's ability to pick up dust and yarn hair, thereby easily causing the circular tubular knitted fabric to be contaminated, and then easily affecting the production quality of the circular tubular knitted fabric.
[0003] Therefore, it is very necessary to design an anti-condensation device applied to a circular knitting machine to solve the above technical problems. Utility Model Content
[0004] The purpose of the utility model is to solve the above-mentioned problems and shortcomings, and to provide an anti-condensation device applied to a large circular knitting machine, which can prevent condensation from forming water droplets on the annular tubular knitted fabric, thereby avoiding the annular tubular knitted fabric from being too easily stained with dust and yarn hair, and thus can greatly reduce the probability of contamination of the annular tubular knitted fabric, which can help improve the production quality of the annular tubular knitted fabric, and has the advantages of simple structure, high reliability, good energy saving effect, etc.
[0005] The technical solution of the utility model is achieved in this way:
[0006] The invention discloses an anti-condensation device applied to a circular knitting machine, which is characterized in that it comprises an outer temperature monitoring module for monitoring the air temperature outside an annular tubular knitted fabric, an inner temperature monitoring module for monitoring the air temperature inside the annular tubular knitted fabric, and a heating module for heating the annular tubular knitted fabric, wherein the outer temperature monitoring module and the inner temperature monitoring module are both electrically connected to the heating module, and the heating module is automatically started when the temperature difference monitored by the outer temperature monitoring module and the inner temperature monitoring module exceeds a set temperature difference, and the heating module is automatically shut down when the temperature difference monitored by the outer temperature monitoring module and the inner temperature monitoring module is lower than a set temperature difference.
[0007] Preferably, the heating module is a horizontally arranged annular heating module.
[0008] Preferably, the anti-condensation device also includes a loop-forming mechanism, the inner-fabric temperature monitoring module is arranged in the inner cavity of the loop-forming mechanism or facing the cavity opening of the inner cavity of the loop-forming mechanism, the outer-fabric temperature monitoring module is arranged on the outside of the loop-forming mechanism and staggered with the cavity opening of the inner cavity of the loop-forming mechanism, and the heating module is arranged in the inner cavity of the loop-forming mechanism or facing the cavity opening of the inner cavity of the loop-forming mechanism or surrounding the cavity opening of the inner cavity of the loop-forming mechanism.
[0009] Preferably, the number of the outer-fabric temperature monitoring modules is more than two, and the outer-fabric temperature monitoring modules are evenly arranged around the axial center line of the loop forming mechanism.
[0010] Preferably, the number of the in-fabric temperature monitoring modules is more than two, and the in-fabric temperature monitoring modules are evenly arranged around the axial center line of the loop forming mechanism.
[0011] The beneficial effects of the utility model are as follows: the anti-condensation device has an outer temperature monitoring module for monitoring the air temperature outside the annular tubular knitted fabric, an inner temperature monitoring module for monitoring the air temperature inside the annular tubular knitted fabric, and a heating module for heating the annular tubular knitted fabric, and the heating module is automatically started when the temperature difference detected by the outer temperature monitoring module and the inner temperature monitoring module is large, and the heating module is automatically turned off when the temperature difference detected by the outer temperature monitoring module and the inner temperature monitoring module is small. In this way, the temperature of the annular tubular knitted fabric can be prevented from being too low, which can prevent the condensation on the annular tubular knitted fabric to form water droplets when the hot air inside the annular tubular knitted fabric contacts the annular tubular knitted fabric, thereby preventing the annular tubular knitted fabric from being too strong in being stained with dust and yarn hair, and thus greatly reducing the probability of contamination of the annular tubular knitted fabric, which can help improve the production quality of the annular tubular knitted fabric. The overall structure of the anti-condensation device is relatively simple and reliable. It can quickly and accurately achieve the anti-condensation effect of heating before condensation occurs, and can automatically stop heating when condensation does not occur. It can not only reliably prevent condensation, but also achieve very good energy-saving effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 This is the second structural schematic diagram of the anti-condensation device in the utility model. DETAILED DESCRIPTION
[0014] like Figure 1 As shown, the utility model discloses an anti-condensation device for use in a circular knitting machine, comprising an outer temperature monitoring module 1 for monitoring the air temperature outside the annular tubular knitted fabric, an inner temperature monitoring module 2 for monitoring the air temperature inside the annular tubular knitted fabric, and a heating module 3 for heating the annular tubular knitted fabric, wherein the outer temperature monitoring module 1 and the inner temperature monitoring module 2 are both electrically connected to the heating module 3, and the heating module 3 is automatically started when the temperature detected by the outer temperature monitoring module 1 differs greatly from that detected by the inner temperature monitoring module 2, and the heating module 3 is automatically shut down when the temperature detected by the outer temperature monitoring module 1 differs slightly from that detected by the inner temperature monitoring module 2.
[0015] The anti-condensation device includes an outer temperature monitoring module 1 for monitoring the air temperature outside the annular tubular knitted fabric, an inner temperature monitoring module 2 for monitoring the air temperature inside the annular tubular knitted fabric, and a heating module 3 for heating the annular tubular knitted fabric. The heating module 3 is automatically started when the temperature difference detected by the outer temperature monitoring module 1 and the inner temperature monitoring module 2 is large, and the heating module 3 is automatically turned off when the temperature difference detected by the outer temperature monitoring module 1 and the inner temperature monitoring module 2 is small. In this way, the temperature of the annular tubular knitted fabric can be prevented from being too low, and when the hot air inside the annular tubular knitted fabric contacts the annular tubular knitted fabric, condensation on the annular tubular knitted fabric can be prevented from forming water droplets, thereby preventing the annular tubular knitted fabric from being too strong in being stained with dust and yarn hair, and thus greatly reducing the probability of contamination of the annular tubular knitted fabric, which can help improve the production quality of the annular tubular knitted fabric. The overall structure of the anti-condensation device is relatively simple and reliable. It can quickly and accurately achieve the anti-condensation effect of heating before condensation occurs, and can automatically stop heating when condensation does not occur. It can not only reliably prevent condensation, but also achieve very good energy-saving effects.
[0016] In the actual manufacturing process, a master control circuit module (not shown in the figure) is set, and the outer temperature monitoring module 1, the inner temperature monitoring module 2, and the heating module 3 are all electrically connected to the master control circuit module, so that the outer temperature monitoring module 1 and the inner temperature monitoring module 2 are electrically connected to the heating module 3 through the master control circuit module, and the outer temperature monitoring module 1 and the inner temperature monitoring module 2 both use the temperature sensor on the existing knitting machine, and the master control circuit module uses a programmable logic controller (PLC) for coordinated control, and the heating module 3 uses an electric heating module. The outer temperature monitoring module 1 and the inner temperature monitoring module 2 transmit the monitored temperature data to the master control circuit module, and the master control circuit module determines whether the temperature difference is large according to the two temperature data; when the temperature difference exceeds the condensation temperature difference (the temperature difference is set to be above 5°C), the master control circuit module starts the heating module 3 to heat the annular tubular knitted fabric through the heating module 3; when the temperature difference is less than the condensation temperature difference, the master control circuit module turns off the heating module 3. In this way, the heating module 3 can be automatically started and turned off, thereby meeting the needs of actual manufacturing and use. Here, only one circuit structure for automatically starting and shutting down the heating module 3 is introduced. In the actual manufacturing process, other circuit structures for automatically starting and shutting down the heating module 3 can also be used.
[0017] The inner temperature monitoring module 2 and the heating module 3 are both supported and positioned by a positioning frame (not shown) arranged in the annular tubular knitted fabric. The positioning frame passes through the annular tubular knitted fabric upward and is fixedly connected to the relevant fixed frame of the circular knitting machine, so that the inner temperature monitoring module 2 and the heating module 3 can be stably installed and positioned in the annular tubular knitted fabric. The outer temperature monitoring module 1 is directly arranged on the frame of the circular knitting machine, so that the requirement of stably installing the outer temperature monitoring module 1 can be met.
[0018] like Figure 1 and Figure 2 As shown, the heating module 3 is a horizontally arranged annular heating module, so that the heat generated by the heating module 3 can be more evenly transferred to the annular tubular knitted fabric, thereby ensuring that the annular tubular knitted fabric is evenly heated, and thus having a more reliable anti-condensation effect.
[0019] like Figure 1 and Figure 2 As shown, in the actual manufacturing process, the heating module 3 can be arranged beside the annular tubular knitted fabric 10 or close to the annular tubular knitted fabric 10; when arranged beside the annular tubular knitted fabric 10, the heating module 3 first heats the surrounding air, and then conducts the heat to the annular tubular knitted fabric 10 to heat it. In this way, the demand for heating the annular tubular knitted fabric can be met.
[0020] In the actual manufacturing process, the heating module 3 can be formed by an electric heating tube or a hot air generating device (in this case, heating is achieved by generating hot air and causing the hot air to act on the annular tubular knitted fabric). The heating module 3 can also be formed by other heating components with heating functions, so as to meet the actual manufacturing and use requirements.
[0021] like Figure 1 and Figure 2 As shown, the anti-condensation device further includes a loop forming mechanism 4, the inner temperature monitoring module 2 is arranged in the inner cavity 41 of the loop forming mechanism 4 or facing the cavity opening of the inner cavity 41 of the loop forming mechanism 4, the outer temperature monitoring module 1 is arranged outside the loop forming mechanism 4 and staggered from the cavity opening of the inner cavity of the loop forming mechanism 4, and the heating module 3 is arranged in the inner cavity 41 of the loop forming mechanism 4 or facing the cavity opening of the inner cavity 41 of the loop forming mechanism 4 or surrounding the cavity opening of the inner cavity 41 of the loop forming mechanism 4. This not only enables the anti-condensation device to monitor the temperature more accurately and stably, but also enables the heat generated by the heating module 3 to act on the annular tubular knitted fabric very stably and reliably, thereby achieving a better anti-condensation effect of the anti-condensation device.
[0022] like Figure 1 and Figure 2 As shown, after adopting the above-mentioned installation structure, the outer temperature monitoring module 1 is located outside the annular tubular knitted fabric 10, the inner temperature monitoring module 2 is located inside the annular tubular knitted fabric 10, and the heating module 3 is horizontally arranged inside the annular tubular knitted fabric 10 or horizontally arranged around the annular tubular knitted fabric 10, so that the temperature can be accurately monitored and the annular tubular knitted fabric can be heated, thereby meeting the anti-condensation requirements very well.
[0023] like Figure 1 and Figure 2 As shown, the number of the outer fabric temperature monitoring modules 1 is more than two, and each outer fabric temperature monitoring module 1 is evenly arranged around the axial center line of the coil forming mechanism 4. This can make the outer fabric temperature monitoring more comprehensive and accurate, thereby further improving the accuracy of starting and shutting down the anti-condensation device.
[0024] like Figure 1 and Figure 2 As shown, the number of the inner temperature monitoring modules 2 is more than two, and each inner temperature monitoring module 2 is evenly arranged around the axial center line of the loop forming mechanism 4. This can make the inner temperature monitoring of the fabric more comprehensive and accurate, thereby further improving the accuracy of starting and shutting down the anti-condensation device.
[0025] The above embodiments are preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made thereto should fall within the protection scope of the present utility model.
