Description

Technical Field

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

[0002] Warp knitting machines are widely used in the weaving of various textiles, especially in the production of 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 operation efficiency of the machine and the quality of the fabric; therefore, it is very necessary to cool the components of the relevant machinery.

[0003] With the development of warp knitting machine technology, the running speed and production efficiency of the equipment have been continuously improved, and the heat generated by the equipment has also been increasing; in this case, the traditional air cooling method can no longer effectively meet the needs of high-efficiency and high-speed production. The water cooling system has become the standard configuration of more and more warp knitting machines due to its high heat dissipation efficiency, strong cooling capacity, small occupied space and other advantages.

[0004] After retrieval, in the current water cooling system, the hot water passing through the mechanical surface is mostly directly injected into the water bucket where the condenser is located for heat exchange; due to the continuous injection of hot water, the water temperature at each position in the bucket will be different, and the temperature difference is relatively large, and the temperature measurement point will not move, resulting in a too large temperature difference between the temperature of most of the water and the water temperature at the water outlet; therefore, we propose a new water cooling device that can evenly the water temperature in the bucket to facilitate the precise control of the cooling rate. Summary of the Invention

[0005] Aiming at the technical problem in the prior art that directly injecting hot water into the condensation bucket causes large water temperature changes 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 solutions:

[0006] A water cooling device for a warp knitting machine, comprising a main water storage cylinder horizontally placed in a tubular structure. Support seats are respectively fixed on the circumferential outer wall of the main water storage cylinder near both ends. A bow-shaped frame is fixed on the side of one of the support seats near the end of the main water storage cylinder. A compression mechanism is fixed at the top of the bow-shaped frame. End covers one and two which are parallel to each other are respectively fixed at both ends of the main water storage cylinder. The same H-shaped steel partition pipe with a "work" - shaped cross - section is inserted between end cover one and end cover two. An "work" - shaped insertion hole adapted to the cross - section of the H-shaped steel partition pipe is opened on end cover two, and the other end of the H-shaped steel partition pipe is clamped with an end - head clamping part. A round hole for the end - head clamping part to pass through is opened in the middle of end cover one. The H-shaped steel partition pipe includes a middle web and arc - shaped plates symmetrically welded on both the upper and lower sides of the middle web. And on both sides of the middle web, the same condensation pipe connected to the compression mechanism is fixed. A vertical inner partition board is fixed on the circumferential inner wall of the main water storage cylinder near the condensation pipe, and the inner partition board divides the inner cavity of the main water storage cylinder into a pre - cooling cavity and a main cooling chamber. All the condensation pipes are located in the main cooling chamber. A rectangular water outlet hole is opened near the top at one end of the inner partition board close to end cover one. And a water inlet pipe is arranged at one end of the outer wall of the main water storage cylinder far from the rectangular water outlet hole.

[0007] Further, a radiator is arranged at one end of the compression mechanism far from the main water storage cylinder. An installation hole is opened in the middle position between the two support seats on the circumferential outer wall of the main water storage cylinder. A filter barrel with an upward - opening and barrel - shaped structure is embedded in the installation hole. A cold - water outlet pipe is inserted at the bottom end of the filter barrel. A filter net plate which is downward - sunken and arc - shaped is clamped at the top - opening of the filter barrel. Since a filter barrel with a filter net plate is arranged in the middle near the bottom of the main water storage cylinder, when discharging cold water, large - particle water scale inside can be prevented from entering the mechanical cooling system and causing blockage.

[0008] Further, staggered water - passing baffle plates are fixed on one side of the inner partition board far from the H-shaped steel partition pipe, and the water flow passing through all the water - passing baffle plates flows in a zigzag shape in the pre - cooling cavity.

[0009] Further, a top fixing block is fixed on the circumferential outer wall of the main water storage cylinder near the top. A control box is fixed near the top on the front of the top fixing block. And an insertion hole one communicating with the pre - cooling cavity is opened at one end of the circumferential outer wall of the main water storage cylinder near the compression mechanism. A rubber ring is embedded in the insertion hole one, and the water inlet pipe is hermetically inserted in the rubber ring. The residence time of the cooling water to be cooled in the pre - cooling cavity can be increased.

[0010] Further, an observation window is opened near the middle of end cover one, and a transparent glass is arranged in the observation window. The observation window is in a long - strip structure, and as much as possible of the internal ice - formation and water - scale conditions can be observed to make corresponding treatments in time.

[0011] Furthermore, the top nozzle 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; this can not only prevent scale from entering the cooling system with a dual effect, but also facilitate the cleaning of the scale in the main water storage cylinder.

[0012] Furthermore, two rotation rib plates distributed symmetrically about the center are rotatably connected to the circumferential outer wall of the H-shaped steel partition pipe. The cross-section of the rotation rib plate is in a T-shaped structure. The same arc-shaped toothed rod is fixedly welded between the side surfaces of the two rotation rib plates; teeth are reserved in the middle of the outer arc side of the arc-shaped toothed rod. A vertical jack two is opened above the tooth of the outer wall of the main water storage cylinder, and a sealed sliding bearing is embedded in the jack two. A reciprocating ejector rod meshing with the teeth is slidably inserted into the sealed sliding bearing; two guide rods pointing to the axis of the main water storage cylinder are slidably inserted at the bottom end of the arc-shaped toothed rod, and the same brush strip is fixed between the bottom ends of the two guide rods. A return spring is arranged between the top end of the brush strip and the outer side surface of the arc-shaped toothed rod.

[0013] Furthermore, a counter wheel frame is fixed to the circumferential inner wall of the main water storage cylinder below the sealed sliding bearing, and a grooved fixed pulley is arranged at one end of the counter wheel frame close to the reciprocating ejector rod, which can tightly press the reciprocating ejector rod against the teeth to ensure tight meshing with the teeth.

[0014] Furthermore, a reduction motor is fixed to the upper surface of the top fixed block obliquely above the reciprocating ejector rod, and a runner is fixed to the top end of the output shaft of the reduction motor; a connecting rod is rotatably connected to the side close to the circumference at the side of the runner away from the reduction motor, and the other end of the connecting rod is rotatably connected to a hinge joint; a plug tube is fixed to the lower surface of the hinge joint, and a compression spring is fixed to the bottom end of the plug tube. A sliding hole is opened at the top end of the reciprocating ejector rod, and the plug tube is slidably inserted into the sliding hole. The bottom end of the compression spring is fixed to the bottom of the sliding hole; an adjusting screw tube is inserted into the circumferential inner wall at the bottom end of the plug tube, and a pressure sensor is fixed to the bottom end of the adjusting screw tube; this can drive the arc-shaped toothed rod to rotate reciprocally, and moreover, once it freezes inside, it will not burn out the reduction motor under the action of the compression spring, playing a protective role for the motor.

[0015] Furthermore, the rotation rib plate includes a flat strip and an arc-shaped strip fixed to the end of the flat strip. The flat strip of the rotation rib plate close to the bottom is respectively provided with circulation holes near both ends; and one-way valve covers are respectively hinged to the two sides of the two circulation holes facing away from each other; Spring abutment frames extending towards the circulation holes are fixed to both sides of the rotation rib plate near the circulation holes; Tightening springs are fixed between the spring abutment frames and the corresponding one-way valve covers; this can accelerate the internal water circulation and ensure that the water temperature difference at each place is small.

[0016] The beneficial effects in the present invention are as follows:

[0017] 1. By setting the inner partition inside the main water storage cylinder, the warm water to be cooled can be decelerated and cooled in the pre-cooling cavity before cooling, and then overflow into the main cooling chamber from the rectangular water outlet holes at a constant speed and impact force for further cooling. At this time, there will be no large disturbance to the cooling water in the main cooling chamber, thus improving the accuracy of temperature control.

[0018] 2. Due to the setting of multiple staggered water passing baffles, the kinetic energy of the cooling water just entering to be cooled is reduced, and the disturbance is minimized, so that it can enter the main cooling chamber slowly and evenly in an overflow manner, and can stay in the pre-cooling cavity for a longer time to cool down in advance.

[0019] 3. By setting two rotating rib plates rotatably connected to the outer wall of the H-shaped steel partition pipe, not only can a slow reciprocating swing be formed during cooling, which is beneficial to the mixing of the internal water area and keeps the water temperature consistent at each position without freezing, but also the brush strips can prevent the surface of the filter mesh plate from being blocked.

A bow-shaped frame is fixed to the side of one of the support seats 4 near the end of the main water storage cylinder 1. A compression mechanism 17 is fixed to the top of the bow-shaped frame. End caps 1 9 and 18 which are parallel to each other are fixed to the two ends of the main water storage cylinder 1. An H-shaped steel stopper tube 23 with an I-shaped cross section is inserted between the end caps 1 9 and the end caps 18.

[0032] Specifically, by means of the inner partition plate 21 arranged inside the main water storage cylinder 1, before cooling the warm water that needs to be cooled, the speed and temperature can be reduced in the pre-cooling cavity first, and then it overflows from the rectangular water outlet hole 2101 into the main cooling chamber at a constant speed and impact force for further cooling. At this time, there will be no large disturbance to the cooling water in the main cooling chamber, thereby improving the accuracy of temperature control.

[0033] In this embodiment, a radiator 2 is arranged at one end of the compression mechanism 17 away from the main water storage cylinder 1, and an installation hole 101 is formed in the circumferential outer wall of the main water storage cylinder 1 at the middle position between the two support seats 4; a filter barrel 5 with an upward opening and a barrel-shaped structure is embedded in the installation hole 101; a cold water outlet pipe 6 is inserted at the bottom end of the filter barrel 5; a filter net plate 29 with a downward concave arc-shaped structure is clamped at the top opening of the filter barrel 5; since the filter barrel 5 with the filter net plate 29 is arranged near the middle of the bottom of the main water storage cylinder 1, when discharging cold water, large particle scale inside can be prevented from entering the mechanical cooling system and causing blockage.

[0037] Refer to Figure 6 , the top pipe orifice of the cold water outlet pipe 6 is higher than the bottom height of the filter barrel 5, and the filter barrel 5 is screwed in the installation hole 101; by setting like this, not only can double protection be achieved to prevent scale from entering the cooling system, but also it is more convenient to clean the scale in the main water storage cylinder 1.

[0038] Refer to Figure 6 、 Figures 8-9 On the circumferential outer wall of the H-shaped steel partition pipe 23, two rotation rib plates 28 distributed centrosymmetrically are rotatably connected.

The same arc-shaped toothed rod 20 is fixedly welded between the side surfaces of the two rotation rib plates 28; teeth are reserved in the middle of the outer arc side of the arc-shaped toothed rod 20. A vertical jack 103 is opened above the tooth of the outer wall of the main water storage cylinder 1, and a sealed sliding bearing 3 is embedded in the jack 103. A reciprocating ejector rod 15 meshing with the teeth is slidably inserted into the sealed sliding bearing 3; two guide rods 2401 pointing to the axis of the main water storage cylinder 1 are slidably inserted at the bottom end of the arc-shaped toothed rod 20, and the same brush strip 24 is fixed between the bottom ends of the two guide rods 2401. A return spring is arranged between the top end of the brush strip 24 and the outer side surface of the arc-shaped toothed rod 20; by arranging two rotation rib plates 28 rotatably connected to the outer wall of the H-shaped steel partition pipe 23, not only can a slow reciprocating swing be formed during cooling, which is beneficial to the mixing of the internal water area, keeping the water temperature consistent at each position and not freezing, but also the brush strip 24 can prevent the surface of the filter net plate 29 from being blocked.

[0039] Refer to Figure 6 and Figure 9 On the inner circumferential wall of the main water storage cylinder 1, a retaining wheel frame 27 is fixed below the sealed sliding bearing 3, and a grooved fixed pulley is arranged at one end of the retaining wheel frame 27 close to the reciprocating ejector rod 15, which can tightly press the reciprocating ejector rod 15 against the teeth to ensure tight meshing with the teeth.

[0040] Refer to Figures 6-7 、 Figure 9 On the upper surface of the top fixing block 12, a reduction motor 13 is fixed obliquely above the reciprocating ejector rod 15, and a runner 14 is fixed at the top end of the output shaft of the reduction motor 13; a connecting rod is rotatably connected to the side close to the circumference at the other side of the runner 14 away from the reduction motor 13, and the other end of the connecting rod is rotatably connected to a hinge joint 19; a plug tube 32 is fixed on the lower surface of the hinge joint 19, and a compression spring 33 is fixed at the bottom end of the plug tube 32.

[0042] Working principle: Before the device is used, 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 the condensation pipe 7 is submerged. At this time, the compression mechanism 17 is turned on to start refrigeration. When the internal temperature detection device detects that the water temperature inside 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 plate 21 arranged inside the main water storage cylinder 1, before cooling the warm water to be cooled, it is first decelerated and cooled in the pre-cooling chamber, and then overflows from the rectangular water outlet hole 2101 into the main cooling chamber at a constant speed and impact force for further cooling. At this time, it will not cause a large disturbance 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 make the two rotating rib plates 28 form a slow reciprocating swing during cooling, in cooperation with the setting of the two circulation holes 2801; it is beneficial to the mixing of the internal water area, keeping the water temperature consistent at each position and not freezing. Moreover, the brush strip 24 can prevent the surface of the filter mesh plate 29 from being blocked.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
