Description

Technical Field

[0001] The invention relates to the technical field of warp knitting machines, and in particular to a water cooling device for warp knitting machines. Background Art

[0002] Warp knitting machines are widely used in weaving various textiles, especially in making high-performance fabrics, non-woven fabrics, etc. Since the working process of warp knitting machines requires high-speed rotation and operation, a large amount of friction and heat will be generated, which may cause the equipment to overheat, affecting the operating efficiency of the machine and the quality of the fabric; therefore, it is very necessary to cool the components of the related machinery.

[0003] With the development of warp knitting machine technology, the operating speed and production efficiency of the equipment are constantly improving, and the heat generated by the equipment is also increasing. In this case, the traditional air cooling method can no longer effectively meet the needs of efficient and high-speed production. The water cooling system has become the standard configuration of more and more warp knitting machines due to its advantages such as high heat dissipation efficiency, strong cooling capacity and small space occupation.

[0004] After searching, it is found that most of the current water cooling systems directly inject hot water that passes through the mechanical surface into the water bucket where the condenser is located for heat exchange; due to the continuous injection of hot water, the water temperature at various positions in the bucket is not the same, and the temperature difference is large, and the temperature measuring point does not move, resulting in a large difference between the temperature of most water and the water temperature at the water outlet; therefore, we propose a new water cooling device that can even out the water temperature in the bucket to facilitate precise control of the cooling rate. Summary of the invention

[0005] In view of the technical problem in the prior art that directly injecting hot water into the condensation barrel causes large variations in water temperature in different water areas inside, making it difficult to control the temperature at the water outlet position within a predetermined temperature difference, the present invention adopts the following technical solution: A water cooling device for a warp knitting machine, comprising a main water storage cylinder placed horizontally and in a tubular structure, wherein support seats are fixed to the circumferential outer wall of the main water storage cylinder near both ends, an arch frame is fixed to the side of one of the support seats near the end of the main water storage cylinder, a compression mechanism is fixed to the top of the arch frame, and an end cover 1 and an end cover 2 parallel to each other are fixed to the two ends of the main water storage cylinder, an H-shaped steel stop tube with an "I"-shaped cross section is inserted between the end cover 1 and the end cover 2, an I-shaped jack matching the cross section of the H-shaped steel stop tube is opened on the end cover 2, and an end clamp is clamped to the other end of the H-shaped steel stop tube; A circular hole is provided in the middle of the end cover 1 for the end clamp to pass through; the H-shaped steel partition tube includes a middle web and arc-shaped plates welded on the upper and lower sides of the middle web and are symmetrical to each other; and the same condenser tube connected to the compression mechanism is fixed on both sides of the middle web; a vertical inner partition is fixed on the circumferential inner wall of the main water cylinder near the condenser tube, and the inner partition divides the inner cavity of the main water cylinder into a pre-cooling chamber and a main cooling chamber; all the condenser tubes are located in the main cooling chamber, and a rectangular water outlet hole is provided at one end of the inner partition close to the end cover 1 and close to the top; and a water inlet pipe is provided at one end of the outer wall of the main water cylinder away from the rectangular water outlet hole.

The observation window is in a long strip structure, and whether there is ice and scaling inside can be observed as much as possible so as to make corresponding treatment in time.

[0010] Furthermore, the top end of the cold water outlet pipe is higher than the bottom height of the filter barrel, and the filter barrel is screwed into the mounting hole; it can not only play a dual role in preventing scale from entering the cooling system, but also is more convenient when cleaning the scale in the main water tank.

[0014] Furthermore, the rotating rib plate includes a flat strip and an arc-shaped strip fixed at the end of the flat strip, and the flat strip of the rotating rib plate near the bottom is provided with circulation holes near both ends; and the two circulation holes are hinged on both sides opposite to each other with a one-way valve cover; spring supports extending toward the circulation holes are fixed on both sides of the rotating rib plate near the circulation holes; and a tightening spring is fixed between the spring supports and the corresponding one-way valve cover; the internal water circulation can be accelerated to ensure that the temperature difference of the water temperature at each location is small.

At this time, no major disturbance will be caused to the cooling water in the main cooling chamber, thereby improving the accuracy of temperature control.

[0016] 2. Due to the provision of multiple staggered water baffles, the kinetic energy of the cooling water just entering the cooling chamber is reduced, and the disturbance is reduced, so that the cooling water can flow into the main cooling chamber at a uniform and slow speed in an overflow manner, and can stay in the pre-cooling chamber for a longer period of time to cool down in advance.

[0017] 3. By setting two rotating rib plates rotatably connected to the outer wall of the H-shaped steel baffle tube, not only can a slow reciprocating swing be formed during cooling, which is beneficial to the mixing of the internal water area and the consistent water temperature at each position to prevent freezing, but also the brush plate strips can prevent the surface of the filter screen from being blocked.

[0031] Working principle: Before using the device, the cooling water to be cooled is first connected to the water inlet pipe 16. After the cooling water slowly fills the pre-cooling chamber, it will overflow from the rectangular water outlet hole 2101 until it submerges the condenser tube 7. At this time, the compression mechanism 17 is turned on to start refrigeration. When the internal temperature detection device detects that the internal water temperature has dropped to the required temperature, it can be discharged from the cold water outlet pipe 6 and then enter the cooling system of the warp knitting machine for circulation; through the inner partition 21 set inside the main water cylinder 1, before the warm water required for cooling is cooled, it is first cooled in the main water cylinder 1. The speed is reduced and the temperature is lowered in the pre-cooling chamber, and then the water overflows from the rectangular water outlet 2101 to the main cooling chamber at a constant speed and impact force for further cooling. At this time, no major disturbance is caused to the cooling water in the main cooling chamber, thereby improving the accuracy of temperature control. At the same time, the reduction motor 13 is started to allow the two rotating rib plates 28 to form a slow reciprocating swing during cooling, in conjunction with the setting of the two circulation holes 2801. This is beneficial to the mixing of the internal water areas, maintaining the water temperature at each position consistent, and preventing ice from forming. In addition, the brush strips 24 can prevent the surface of the filter screen plate 29 from being blocked.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
