Description

Technical Field

[0001] This application relates to the field of circular knitting machine technology, and more particularly to a heat dissipation structure for a circular knitting machine. Background Technology

[0002] A circular knitting machine is a core piece of equipment used for mass production of cylindrical or sheet-like knitted fabrics. It weaves yarn into different structures through the cyclical movement of needles on the cylinder. However, during the operation of a circular knitting machine, the mechanical friction of the motor and transmission components generates a lot of heat. At the same time, the high-speed reciprocating motion of the needles and cylinder also generates heat due to friction. Most existing circular knitting machines use natural cooling or top air blowing, which cannot cool the transmission components and remove heat in time. This leads to excessively high temperatures in key components of the equipment, directly affecting operational stability and service life. Utility Model Content

[0004] The technical solution of this application is implemented as follows: This application provides a heat dissipation structure for a circular knitting machine, including a machine foot with a three-pronged fork on which a fabric winding machine is mounted. The machine foot also has a dismounting seat on which a needle cylinder is placed. The heat dissipation structure also includes a heat dissipation component. Side plates and a support plate are respectively provided on both sides of the fabric winding machine. The heat dissipation component includes a housing and a water tank. The housing is mounted on the side plate and has two sets of spaced connectors inside. The water tank is mounted on the support plate. A first water pump is also installed on one side of the water tank. The input end of the first water pump is connected to the water tank through a pipe, and the output end is connected to an output pipe.

The output end of the output tube is connected to the syringe and communicates with the heat dissipation cavity. The tank is equipped with a connecting pipe, both ends of which extend to the outside of the tank and have connectors. The water tank is also connected to an inlet pipe that connects to one set of connectors. Another set of connectors is connected to a return pipe, one end of which is installed on a syringe and communicates with the heat dissipation cavity. When the fabric rolling machine and the needle cylinder rotate synchronously, the heat dissipation components rotate synchronously with the cooperation of the side plate and the support plate.

[0019] Reference Figures 1-5 A heat dissipation structure for a circular knitting machine includes a machine foot 1 with a three-pronged fork 11. A fabric winding machine 12 is mounted on the three-pronged fork 11. The fabric winding machine 12 is a type of fabric winding machine capable of synchronous rotation, as is known to those skilled in the art. The connection between the fabric winding machine 12 and the three-pronged fork 11 is not described in detail here. The machine foot 1 also has a dismounting seat 13, on which a needle cylinder 14 is placed. The structure also includes a heat dissipation assembly 2. Side plates 121 and a support plate 122 are respectively provided on both sides of the fabric winding machine 12. The heat dissipation assembly 2 is mounted on the side plates 121. The heat dissipation component 2 is used to dissipate heat from the syringe 14. It also includes a heat dissipation component 2. The two sides of the fabric rolling machine 12 are respectively provided with a side plate 121 and a support plate 122. The heat dissipation component 2 includes a housing 21 and a water tank 22. The housing 21 is installed on the side plate 121. Two sets of spaced connectors are provided inside the housing 21. The water tank 22 is installed on the support plate 122. A first water pump component 23 is also installed on one side of the water tank 22. The first water pump component 23 adopts a booster pump in the prior art. The input end of the first water pump component 23 is connected to the water tank 22 through a pipe, and the output end is connected to an output pipe 24. One end of the output tube 24 is located on one side of the syringe 14. The inner wall of the syringe 14 is provided with a heat dissipation cavity 141. The output end of the output tube 24 is connected to the syringe 14 and communicates with the heat dissipation cavity 141. Through the cooperation of the output tube 24 and the return tube 27, the liquid in the water tank 22 can be input into the syringe 14. The housing 21 is equipped with a connecting pipe 211. Both ends of the connecting pipe 211 extend to the outside of the housing 21 and have connectors. The water tank 22 is also connected to an inlet pipe 26, which is connected to one set of connectors. The other set of connectors is connected to a return pipe 27. One end of the return pipe 27 is installed on the syringe 14 and communicates with the heat dissipation cavity 141. The connecting pipe 211 can be made of metal, which allows the liquid in the return pipe 27 to undergo preliminary heat exchange before entering the inlet pipe 26, thereby achieving preliminary temperature reduction. When the fabric rolling machine 12 and the needle cylinder 14 rotate synchronously, the heat dissipation assembly 2 rotates synchronously with the cooperation of the side plate 121 and the support plate 122. The synchronous rotation method can avoid interference caused by the output pipe 24 or the return pipe 27 maintaining their relative positions during rotation.

[0020] Based on the above structure, by installing the output pipe 24 and the return pipe 27 on the inner wall of the needle cylinder 14 respectively, after the circular knitting machine is turned on, the fabric winding machine 12 and the needle cylinder 14 start to rotate synchronously under the drive of the main machine. At the same time, the first water pump 23 starts. The first water pump 23 draws low-temperature coolant from the water tank 22 through the input end pipe and flows towards the needle cylinder 14 through the output pipe 24. The coolant enters the heat dissipation cavity 141 on the inner wall of the needle cylinder 14 through the output pipe 24 and directly contacts the heated inner wall of the needle cylinder 14, absorbing the frictional heat and conductive heat generated by the needle cylinder 14 during the knitting process, thereby reducing the heat generated by the needle cylinder 14 during operation. Furthermore, the return pipe 27 enables the coolant to be returned, thereby realizing the circulation of the coolant and solving the problem that existing circular knitting machines cannot cool the transmission components.

[0021] In one embodiment, reference is made to Figures 1-4 On the other side of the water tank 22, a second water pump component 25 is also installed. The second water pump component 25 is a booster water pump in the prior art. Part of the water inlet pipe 26 is connected to the input end of the second water pump component 25, and the other part is connected to the output end of the second water pump component 25, so that the second water pump component 25 is connected to the water tank 22. With the cooperation of the second water pump component 25, the coolant in the syringe 14 can be quickly drawn, thereby improving the circulation efficiency of the liquid.

[0022] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 5 Inside the housing 21, a fan component 3 is also installed. The fan component 3 is a fan device driven by a motor, which is a common technology. The output end of the fan component 3 faces the inside of the housing 21. The part of the pipe located in the housing 21 is between the fan component 3 and the inner wall of the housing 21. The fan component 3 blows air onto the connecting pipe 211, which accelerates the air flow on the surface of the connecting pipe 211, cools the coolant that is about to enter the water tank 22 in advance, and removes the heat generated by the heat dissipation of the connecting pipe 211 inside the housing 21, reduces its initial temperature, and improves the subsequent heat exchange efficiency.

[0023] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4A first heat sink 142 is provided inside the heat dissipation cavity 141. Several first heat sinks 142 are provided and sealed and spliced ​​on the side wall of the syringe 14. The first heat sink 142 is made of aluminum metal and has the characteristics of high thermal conductivity and large specific surface area. It can increase the contact area between the coolant and the inner wall of the syringe 14, and at the same time accelerate the heat transfer from the wall of the syringe 14 to the coolant, thus optimizing the heat exchange efficiency inside the syringe 14. When the coolant flows through the first heat sink 142, it can absorb the heat of the syringe 14 more quickly and fully, thus preventing heat from accumulating on the wall of the syringe 14.

[0024] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 5 The enclosure 21 is also filled with a second heat sink 212, which is also made of aluminum. The tube is located inside the second heat sink 212. The coolant flowing inside the tube carries some heat. By tightly fitting the tube, the second heat sink 212 can fix the tube and prevent it from shaking inside the enclosure 21. On the other hand, through its own thermal conductivity, it can help absorb the heat emitted by the tube and transfer the heat to the outside of the enclosure 21, thus preventing heat from accumulating inside the tube and playing a role in heat dissipation.

[0025] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 5 The enclosure 21 is also equipped with several vents 213, which are spaced apart along the length of the enclosure 21. Through the cooperation of several vents 213, the interior of the enclosure 21 is connected to the outside. The heat generated inside the enclosure 21 due to the pipes and honeycomb aluminum can be convected with the outside cold air through the vents 213, actively expelling the hot air and maintaining the low temperature environment inside the enclosure 21, thus achieving passive ventilation. Furthermore, the vents 213 can ensure basic ventilation even when the fan stops working, preventing the enclosure 21 from becoming a heat source, indirectly ensuring the cooling effect of the coolant, and improving the reliability of the system.

[0026] In one embodiment, reference is made to Figure 1 and Figure 3 The fabric rolling machine 12 is equipped with a fabric rolling swing arm 123. The output pipe 24 and the return pipe 27 are partially attached to the fabric rolling machine 12 and the fabric rolling swing arm 123. The fabric rolling swing arm 123 can fix the position of the pipe, prevent the pipe from shaking or colliding due to centrifugal force when the equipment rotates, reduce the risk of pipe damage, ensure uninterrupted water circulation, and improve the stability of the structure. In addition, the pipe is attached to the fabric rolling swing arm 123 and the fabric rolling machine 12 to avoid messy distribution, save internal space of the equipment, reduce friction between the pipe and other components, extend service life, and optimize the spatial layout.
