Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically a cooling device for a high-precision circular knitting machine needle cylinder. Background Technology

[0002] The cylinder of a circular knitting machine is one of the most critical components of a circular knitting machine (the core equipment for producing knitted fabrics). It is a precision, vertically placed cylindrical component with a large number of parallel needle grooves distributed around its circumference. The knitting needles used in textiles are precisely placed in these needle grooves. When it is working, it rotates, and the friction of rotation generates a lot of heat. Therefore, a cooling device is needed to cool the cylinder in real time to avoid affecting the textile effect.

[0003] In the prior art, Chinese Patent Application No. CN201921006862.X discloses a cooling system for a large circular knitting machine syringe, including a large circular knitting machine body, a cooling pipe, a cooling channel, a cooling chamber, and a sealing plate; the cooling chamber is located inside the large plate of the large circular knitting machine body; the cooling pipe is fixed on the side wall of the large plate of the large circular knitting machine body and communicates with the interior of the cooling chamber; the cooling channel is fixed on the inner wall of the syringe of the large circular knitting machine body and communicates with the needle groove of the syringe, the cooling channel is a spiral channel, the cooling channel communicates with the interior of the cooling chamber through air holes, and the air holes are evenly distributed at the bottom of the syringe of the large circular knitting machine body; the sealing plate is fixed on the inner side of the bottom of the syringe of the large circular knitting machine body, and the sealing plate is slidably connected to the large plate of the large circular knitting machine body through a sliding mechanism.

[0004] Based on the above information, it can be seen that existing cooling devices generally achieve cooling by increasing airflow through blowing air. However, in actual use, the cooling device is installed inside the large circular knitting machine, which makes the working environment of the cooling device itself relatively high, resulting in limited cooling effect.

[0005] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Summary of the Invention

[0006] The main objective of this invention is to provide a high-precision cooling device for syringes of large circular knitting machines, in order to solve the problem of limited cooling effect mentioned in the background art.

[0007] To achieve the above objectives, the solution of this utility model is: A high-precision large circular knitting machine syringe cooling device includes a cylindrical syringe body with a cooling box installed inside the syringe body. The cooling box has matrix-distributed air outlets on its left and right sides, corresponding to the inner walls of the syringe body. A water storage chamber is located in the center of the cooling box, and drying chambers are located on the left and right sides. A delivery pump is fixedly installed outside the water storage chamber, and an air supply pipe is installed at the lower end of the delivery pump. Air is delivered to the water storage chamber through the delivery pump and air supply pipe, and then delivered to the drying chambers on the left and right sides through connecting pipes. Finally, the air is discharged from the air outlets on the left and right sides of the cooling box and blown towards the inner walls of the syringe body, thereby using airflow to cool the syringe body. The water storage chamber contains cooling water for cooling the air. When air enters the water storage chamber, it first comes into contact with the cooling water, which cools the air, ensuring the subsequent cooling effect. A stirring mechanism is also installed inside the water storage chamber.

[0008] Preferably, two connecting pipes are fixedly installed above the cooling box, and the water storage tank and the drying tank are connected by the connecting pipes.

[0009] Preferably, a semiconductor cooling chip is fixedly installed on the inner wall of the water storage tank to cool the cooling water.

[0010] Preferably, the upper surface of the cooling box is fixedly equipped with upper heat dissipation fins arranged at equal intervals, and the lower surface of the cooling box is fixedly equipped with lower heat dissipation fins arranged at equal intervals.

[0011] Preferably, the drying chamber is equipped with a water-absorbing sponge for drying the air.

[0012] Preferably, the stirring mechanism includes a stirring rod rotatably installed inside the water storage tank, and the stirring rod is driven to rotate by a driven bevel gear fixedly installed coaxially with it.

[0013] Preferably, the driven bevel gear is meshed with a driving bevel gear that is rotatably mounted to the cooling box below the driven bevel gear, and a friction roller located outside the cooling box is fixedly mounted below the driving bevel gear, and the friction roller is in contact with and rubs against the inner wall of the syringe body.

[0014] With the above structure, the beneficial effects of the cooling device for high-precision large circular knitting machine syringes involved in this utility model are: 1. Air is delivered to the water storage tank through a delivery pump and air supply pipe, and then delivered to the drying chambers on the left and right sides through connecting pipes. Finally, it is discharged from the air outlets on the left and right sides of the cooling box and blown onto the inner wall of the syringe body, thereby using airflow to cool the syringe body. Furthermore, the water storage tank contains cooling water. When air enters the water storage tank, it first comes into contact with the cooling water, which cools the air and ensures the subsequent cooling effect. In addition, a semiconductor cooling chip is installed inside the water storage tank to cool the cooling water.

[0015] 2. During the operation of the syringe body, the large circular knives drive the rotation. During this process, the inner wall of the syringe body contacts and rubs against the friction rollers, which causes the friction rollers to drive the active bevel gear to rotate. The active bevel gear drives the driven bevel gear that meshes with it to rotate, which in turn drives the stirring rod to rotate. The stirring rod agitates the cooling water inside the water storage tank, and the semiconductor cooling chip cools the water. Attached Figure Description

Detailed Implementation

[0018] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0019] Example 1: Please refer to Figures 1-5To improve the cooling effect, this embodiment provides the following technical solution, specifically: a syringe body 1 with a cylindrical structure, a cooling box 2 installed inside the syringe body 1 and mounted on the main body of the large circular knitting machine, air outlets 3 arranged in a matrix on the left and right sides of the cooling box 2, the air outlets 3 corresponding to the inner wall of the syringe body 1, a water storage chamber 6 in the middle of the interior of the cooling box 2, and drying chambers 7 on the left and right sides of the interior of the cooling box 2, a delivery pump 4 fixedly installed outside the lower part of the water storage chamber 6, and an air supply pipe 5 installed at the lower end of the delivery pump 4, and the water storage chamber 6 stores cooling water for cooling the air, two connecting pipes 9 fixedly installed above the cooling box 2, and the water storage chamber 6 and the drying chamber 7 are connected by the connecting pipes 9, a semiconductor cooling chip 8 fixedly installed on the inner side wall of the water storage chamber 6, upper heat dissipation fins 10 arranged at equal intervals fixedly installed on the upper surface of the cooling box 2, and lower heat dissipation fins 11 arranged at equal intervals fixedly installed on the lower surface of the cooling box 2, and a water-absorbing sponge 12 for drying the air fixedly installed inside the drying chamber 7.

[0020] When using the device, first, the cooling box 2 is fixedly installed inside the syringe body 1, and the cooling box 2 is fixedly connected to the large circular knitting machine. When the large circular knitting machine is working, it drives the syringe body 1 to rotate. At the same time, the delivery pump 4 below the cooling box 2 is turned on. The delivery pump 4, together with the air supply pipe 5, delivers air to the water storage tank 6. At this time, the air comes into contact with the cooling water inside the water storage tank 6 (the cooling water cools the air, and the water storage tank 6 is equipped with a semiconductor cooling chip 8, which cools the cooling water in the water storage tank 6). The cooled air is delivered to the drying chambers 7 on the left and right sides through the connecting pipe 9. At this time, the water-absorbing sponge 12 in the drying chamber 7 absorbs the moisture in the air to achieve the purpose of drying. Finally, the air is discharged from the air outlet 3 on the left and right sides of the cooling box 2, and the airflow blows into the syringe body 1 to achieve the purpose of cooling the syringe body 1.

[0021] Example 2: Please refer to Figures 4-6 In order to achieve the purpose of stirring, this embodiment provides the following technical solution, which specifically discloses that: a stirring mechanism is provided inside the water storage tank 6. The stirring mechanism includes a stirring rod 13 rotatably installed inside the water storage tank 6. The stirring rod 13 is driven to rotate by a driven bevel gear 14 coaxially fixedly installed thereon. A driving bevel gear 15 rotatably installed with the cooling box 2 is meshed below the driven bevel gear 14. A friction roller 16 located outside the cooling box 2 is fixedly installed below the driving bevel gear 15. The friction roller 16 is in contact with and rubs against the inner wall of the syringe body 1.

[0022] During the rotation of the syringe body 1, its inner wall comes into contact with and rubs against the friction roller 16, which causes the friction roller 16 to drive the active bevel gear 15 to rotate. At this time, the driven bevel gear 14, which is meshed with the active bevel gear 15, drives the stirring rod 13 to rotate. The stirring rod 13 stirs the cooling water inside the water storage tank 6, thereby improving the cooling effect of the semiconductor cooling chip 8 on the cooling water.
