Description

Technical Field

[0001] The invention relates to the technical field of warp knitting machines, in particular to a warp knitting machine with a knitting needle bed swing amplitude adjustment function, and also to a use method of the warp knitting machine with a knitting needle bed swing amplitude adjustment function. Background Art

[0002] Warp knitting machines are important equipment in the textile industry and are mainly used to produce various warp knitted fabrics, such as knitted underwear, sportswear, decorative fabrics, etc. During the operation of the warp knitting machine, the swing amplitude of the needles and needle beds has an important influence on the quality and production efficiency of the fabric. Warp knitting machines usually run at high speeds, and the wear between the two parts that are connected and run at high speeds is relatively large.

[0003] The patent with announcement number CN114150429B discloses a high-speed warp knitting machine with a knitting needle bed swinging mechanism, which is provided with a lubrication bin, a fixing bolt and an adding cover at the connection between the output rod and the guide rod. Before the high-speed warp knitting machine is operated, the adding cover is removed and the lubricating oil is added into the lubrication bin. When the output rod and the guide rod rotate relative to each other, the lubricating oil lubricates the output rod and the guide rod, thereby reducing the wear caused by the relative rotation between the output rod and the guide rod, and facilitating quick and convenient lubrication between the output rod and the guide rod.

[0004] Although the above solution effectively alleviates the wear problem between the output rod and the guide rod, lubricating oil is an indispensable consumable.

DETAILED DESCRIPTION

[0036] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] Reference Figures 1 to 11 As shown: a warp knitting machine with a needle bed swing amplitude adjustment function, comprising a connecting shaft 12 for connecting an output rod 11 and a guide rod 13, both ends of the connecting shaft 12 are provided with oil chambers 121, the middle of the connecting shaft 12 is provided with an oil outlet 122 connected to the oil chamber 121, a fixed bracket 2 is provided on one side of the connecting shaft 12, and two oil injection mechanisms 3 and a linkage mechanism 4 are provided on the fixed bracket 2; the two oil injection mechanisms 3 are respectively provided at both ends of the fixed bracket 2, the oil injection mechanism 3 comprises an oil storage tank 31 and an oil injection structure 32, the oil storage tank 31 is transparent, and the upper and lower ends of the oil storage tank 31 are respectively provided with an oil injection port and an oil outlet, and the oil injection structure 32 is provided on the oil storage tank 31 At the lower end, the oil injection structure 32 includes an oil injection pipe 321, a liquid inlet connected to the oil outlet is opened in the middle of the oil injection pipe 321, a liquid outlet is opened at one end of the oil injection pipe 321, a push rod 322 is coaxially arranged in the oil injection pipe 321, a piston head 3221 is arranged at one end of the push rod 322, the other end of the push rod 322 extends out of the oil injection pipe 321, and a liquid guide pipe 323 connected to the oil chamber 121 is arranged at the liquid outlet; the linkage mechanism 4 is arranged between the two oil injection mechanisms 3, and the linkage mechanism 4 connects the connecting shaft 12 with the two push rods 322 in the two oil injection mechanisms 3; when the output rod 11 is swinging, the automatic injection of lubricating oil is realized through the linkage mechanism 4.

[0038] According to the requirements of the processed products, the operator can adjust the length of the guide rod 13 to directly adjust the swing amplitude of the knitting needles and the needle bed; during the swinging process, the output rod 11 drives the guide rod 13 to move through the connecting shaft 12, and the guide rod 13 will rotate around the axis of the connecting shaft 12. As the swinging frequency increases, the friction between the connecting shaft 12 and the guide rod 13 gradually increases, so the connection between the two needs to be continuously lubricated; when the output rod 11 drives the connecting shaft 12 to swing, the linkage mechanism 4 will synchronously drive the push rods 322 in the two oil injection mechanisms 3 to move back and forth, and the movement of the push rods 322 will drive the piston head 3221 to move from one end of the oil injection pipe 321 to the other end, and the lubricating oil in the oil storage tank 31 will be sucked into the oil injection pipe 321 through the negative pressure, and then the push rod 322 pushes the piston head 3221 to reset, so that the oil injection pipe 321 The lubricating oil in the oil chamber 121 of the connecting shaft 12 is injected into the oil chamber 121 of the connecting shaft 12 through the liquid guide tube 323, and the lubricating oil overflows from the oil outlet hole 122, and finally reaches the connection between the connecting shaft 12 and the guide rod 13 to achieve the lubrication effect. As the output rod 11 continues to swing, the connecting shaft 12 continuously drives the oil injection mechanism 3 to work through the linkage mechanism 4, ensuring that the lubricating oil can be continuously injected into the connection between the connecting shaft 12 and the guide rod 13, so that the friction surface between the two is always fully lubricated. In addition, the oil storage tank 31 is made of transparent material, and the operator can clearly observe the remaining lubricating oil in the tank and replenish it at any time during the operation of the warp knitting machine to ensure the continuous and stable operation of the lubrication system, thereby achieving the lubrication effect between the connecting shaft 12 and the guide rod 13 remains unchanged, reducing wear and energy loss, and ensuring the efficient operation of the warp knitting machine.

[0039] Reference Figure 3 , Figure 4 and Figure 5As shown: the linkage mechanism 4 includes a linkage transmission structure 41, two transmission arm structures 42 and a synchronous drive structure 43; the middle part of the linkage transmission structure 41 is transmission-connected to the connecting shaft 12; the two transmission arm structures 42 are respectively arranged at the two ends of the linkage transmission structure 41, and the transmission arm structure 42 includes a second vertical plate 421 and a first drive plate 422, the upper end of the second vertical plate 421 is connected to the linkage transmission structure 41, one end of the first drive plate 422 is connected to the other end of the second vertical plate 421, and there is an angle between the first drive plate 422 and the second vertical plate 421, and a second slide groove 4221 is provided on the first drive plate 422; the synchronous drive structure 43 includes a rectangular Frame 431, two second transmission rods 432 and four second drive plates 433, the rectangular frame 431 is fixed on the fixed bracket 2, the two oil filling pipes 321 are respectively arranged at the two ends of the rectangular frame 431, the two second transmission rods 432 are respectively arranged on both sides of the rectangular frame 431, one end of the second transmission rod 432 is provided with a transmission pin 4321, the transmission pin 4321 is slidably connected with the second slide groove 4221, and the other end of the transmission pin 4321 passes through the rectangular frame 431, the four second drive plates 433 are respectively arranged on both sides of the two second transmission rods 432, and the two ends of the second drive plate 433 are respectively axially connected with the second transmission rod 432 and the push rod 322.

[0040] When the connecting shaft 12 moves, its power is transmitted to the two transmission arm structures 42 via the linkage transmission structure 41 to ensure that the two realize synchronous movement. During this process, the second vertical plate 421 in the transmission arm structure 42 performs up and down movement in the vertical direction; when the second vertical plate 421 moves downward, the second vertical plate 421 drives the first driving plate 422 to move downward synchronously, and then applies a thrust to the second transmission rod 432 through the second slide groove 4221. Since the second transmission rod 432 is restricted by the rectangular frame 431, the second transmission rod 432 can only move along its own axial direction. Therefore, the cooperation mechanism of the second slide groove 4221 and the transmission pin shaft 4321 pushes the second transmission rod 432 to the rectangular frame The frame 431 moves inside, causing the two second driving plates 433 at both ends of the second transmission rod 432 to apply a thrust toward the inside of the oil filling pipe 321 to the two push rods 322 respectively, so that the push rods 322 push the hydraulic oil to move into the oil chamber 121. On the contrary, when the second vertical plate 421 moves upward, the second slide groove 4221 on the first driving plate 422 applies a pulling force to the second transmission rod 432 through the transmission pin shaft 4321, so that the second transmission rod 432 moves toward the outside of the rectangular frame 431, and the lubricating oil in the oil storage tank 31 is drawn into the oil filling pipe 321. The connecting shaft 12 can complete the injection of lubricating oil once within a complete movement cycle, thereby effectively stabilizing the supply of lubricating oil.

[0041] The present application links the supply of lubricating oil with the swing of the output rod 11. By changing the swing speed of the output rod 11, the supply speed of lubricating oil can be changed immediately, thereby avoiding the delay of indirectly controlling the supply of lubricating oil.

[0042] Reference Figure 5 and Figure 6 As shown: the transmission arm structure 42 also includes an angle adjustment structure 423, which is arranged between the second vertical plate 421 and the first driving plate 422. The angle adjustment structure 423 includes a first connecting block 4231, a second connecting block 4232 and an adjusting bolt 4233. Both ends of the first connecting block 4231 are axially connected to the second vertical plate 421, the second connecting block 4232 is axially connected to the first driving plate 422, and the adjusting bolt 4233 is spirally arranged inside the first connecting block 4231, and one end of the adjusting bolt 4233 is connected to the second connecting block 4232.

[0043] The first drive plate 422 is capable of rotating around the connection between it and the second vertical plate 421. At present, some intelligent knitting needle bed swing mechanisms are provided with a swing speed adjustment kinetic energy to meet the swing speed requirements of the knitting needle bed in different production processes. When the swing speed is faster, the frequency of transmission between the connecting shaft 12 and the guide rod 13 increases, and the heat generated by the friction between the two will also increase. Although the connecting shaft 12 can speed up the supply speed of the lubricating oil to meet the lubrication effect between the two, it is impossible to increase the amount of lubricating oil supplied at a single time, resulting in that the heat generated by the friction cannot be taken away in time. When the swing speed of the swing mechanism is accelerated, the operator rotates the adjusting bolt 4233 clockwise to move the adjusting bolt 4233 toward the first drive plate 422. This movement causes the second connecting block 4232 to be acted upon by the thrust of the adjusting bolt 4233, thereby driving the first drive plate 422 to rotate, so that the angle between the first drive plate 422 and the second vertical plate 421 gradually increases. During the descent of the second vertical plate 421, the first drive plate 422 is rotated. The second slide groove 4221 on the movable plate 422 pushes the second transmission rod 432 to move a distance that increases accordingly. This increased movement distance further causes the second transmission rod 432 to push the push rod 322 in the oil filling pipe 321 to move a distance that increases, thereby achieving a single injection of more lubricating oil into the oil chamber 121 to quickly take away the heat generated by the friction between the connecting shaft 12 and the guide rod 13. On the contrary, when the swinging speed of the swinging mechanism slows down, the operator rotates the adjusting bolt 4233 counterclockwise to gradually reduce the angle between the first driving plate 422 and the second vertical plate 421. During the descending process of the second vertical plate 421, the second slide groove 4221 on the first driving plate 422 pushes the second transmission rod 432 to move a distance that decreases accordingly. The reduced movement distance further causes the second transmission rod 432 to push the push rod 322 in the oil filling pipe 321 to move a distance that decreases, thereby reducing the amount of lubricating oil injected at a single time, thereby reducing the amount of lubricating oil used, thereby achieving control of the single lubricating oil injection amount and making reasonable use of the lubricating oil.

[0044] Reference Figure 4 and Figure 7 As shown: the linkage transmission structure 41 includes two transmission plates 411, a first transmission rod 412, a linkage plate 413 and four guide structures 414. The two transmission plates 411 are respectively fixedly arranged at the two ends of the connecting shaft 12; the two ends of the first transmission rod 412 are respectively connected to the two transmission plates 411, and the first transmission rod 412 is parallel to the connecting shaft 12; the linkage plate 413 is horizontally arranged at the lower end of the connecting shaft 12, and the linkage plate 413 is connected to the first transmission rod 412, and the two ends of the linkage plate 413 are respectively connected to the upper ends of the two second vertical plates 421; the four guide structures 414 are respectively arranged on both sides of the two ends of the linkage plate 413.

[0045] When the connecting shaft 12 starts to move, the connecting shaft 12 will directly drive the two transmission plates 411 fixedly connected thereto to move synchronously. Since the two ends of the first transmission rod 412 are respectively connected to the two transmission plates 411, the first transmission rod 412 will also move synchronously and in the same direction as the connecting shaft 12. As the first transmission rod 412 moves, the first transmission rod 412 drives the linkage plate 413 connected thereto to move. At this time, the linkage plate 413 will be constrained and guided by the four guide structures 414 to ensure that it moves back and forth in the direction defined by the guide structure 414. During the movement of the linkage plate 413, the two transmission arm structures 42 will be driven to perform corresponding reciprocating motion in the vertical direction. The movement of the connecting shaft 12 is transmitted to the two transmission arm structures 42 through the linkage transmission structure 41, thereby realizing the linkage function between the connecting shaft 12 and the two transmission arm structures 42.

[0046] Reference Figure 7 As shown, a first sliding groove 4131 is opened in the middle of the linkage plate 413 , and the first transmission rod 412 is slidably disposed in the first sliding groove 4131 .

[0047] During the movement of the connecting shaft 12, it will simultaneously generate displacements in the vertical direction and the horizontal direction, and these displacements will be directly transmitted to the first transmission rod 412 connected thereto, causing the first transmission rod 412 to move in the same direction. If the linkage plate 413 is directly and rigidly connected to the first transmission rod 412, the horizontal displacement of the first transmission rod 412 will directly drive the linkage plate 413 and the two transmission arm structures 42 connected thereto to move in the horizontal direction, which is inconsistent with the expected movement mode. By providing a first sliding groove 4131 on the linkage plate 413 and sliding the first transmission rod 412 in the first sliding groove 4131, the first transmission rod 412 can be moved in the vertical direction. The movement can be effectively transmitted to the linkage plate 413 with the cooperation of the first slide groove 4131, driving the linkage plate 413 and the two transmission arm structures 42 connected thereto to make corresponding movements in the vertical direction. The first transmission rod 412 moves in the horizontal direction, causing it to slide along the path of the first slide groove 4131. During the sliding process, not only the connection between the first transmission rod 412 and the linkage plate 413 is maintained, but also it is ensured that the linkage plate 413 itself will not produce unnecessary displacement in the horizontal direction, so that the first transmission rod 412 can effectively transmit the effective part of its movement to the linkage plate 413, thereby realizing effective linkage between the first transmission rod 412 and the linkage plate 413.

[0048] Reference Figure 7 and Figure 8As shown: the guide structure 414 includes a first vertical plate 4141, two guide columns 4142 and a slider 4143; the lower end of the first vertical plate 4141 is connected to the fixed bracket 2; the two guide columns 4142 are arranged parallel to each other, and the two ends of the guide columns 4142 are respectively connected to the two ends of the first vertical plate 4141; the two ends of the slider 4143 are respectively slidably connected to the two guide columns 4142, and the middle part of the slider 4143 is connected to the linkage plate 413.

[0049] When the first transmission rod 412 moves in the first slide groove 4131, a friction force will be generated between the first slide groove 4131 and the linkage plate 413. The friction force will cause the linkage plate 413 to have a tendency to move horizontally. In order to avoid the problem of uneven effects of the two transmission arm structures 42 on the two second transmission rods 432 caused by the offset of the linkage plate 413, guide structures 414 are provided at both ends of the linkage plate 413. When the first transmission rod 412 drives the linkage plate 413 to move, the linkage plate 413 will drive the slider 4143 to slide back and forth along the guide column 4142. During this process, the horizontal force acting on the linkage plate 413 will be vertically transmitted to the surface of the guide column 4142 through the slider 4143. The guide column 4142 effectively constrains the horizontal movement of the slider 4143, ensuring that the linkage plate 413 only moves in the vertical direction, thereby maintaining the consistency of the effects of the two transmission arm structures 42 on the two second transmission rods 432.

[0050] Reference Figure 3 and Fig. 9 As shown: the oil injection structure 32 also includes a first automatic valve 324, the two ends of the first automatic valve 324 are respectively connected to the oil outlet and the liquid inlet, the first automatic valve 324 includes a first valve body 3241, a first partition plate 3242 is arranged inside the first valve body 3241, a plurality of first flow ports are opened on the first partition plate 3242, a first movable rod 3243 slidingly connected to the first partition plate 3242 is arranged inside the first valve body 3241, first sealing plates 3244 are arranged at both ends of the first movable rod 3243, a first spring 3245 is sleeved on one end of the first movable rod 3243 facing the oil storage tank 31, and the two ends of the first spring 3245 are respectively abutted against the first sealing plate 3244 and the first partition plate 3242.

[0051] When the oil storage tank 31 is directly connected to the oil filling pipe 321, although the push rod 322 can draw the lubricating oil in the oil storage tank 31 into the oil filling pipe 321 through the action of negative pressure, during the process of the push rod 322 pushing the lubricating oil into the oil chamber 121, part of the lubricating oil will flow back to the oil storage tank 31. Therefore, a first automatic valve 324 is set between the oil storage tank 31 and the oil filling pipe 321. When the oil filling pipe 321 draws the lubricating oil in the oil storage tank 31 through the action of negative pressure, the negative pressure suction force acts on the first sealing plate 3244 close to the side of the oil filling pipe 321, making it away from the first partition plate 3242 to form a gap. At the same time, the first sealing plate 3244 on the other side compresses the first spring 3245, so that the first spring 3245 can be turned off. A spring 3245 stores elastic potential energy. At this time, the first flow port on the first partition 3242 is exposed, allowing the lubricating oil to flow to the oil filling pipe 321 through the first flow port. On the contrary, when the oil filling pipe 321 supplies oil to the oil chamber 121, the lubricating oil pressure in the oil filling pipe 321 increases, and a force is generated on both first sealing plates 3244 toward the oil storage tank 31. With the assistance of the first spring 3245 releasing the elastic potential energy, the first sealing plate 3244 close to the side of the oil filling pipe 321 is tightly attached to the first partition 3242, closing the first flow port, and effectively preventing the lubricating oil from flowing back to the oil storage tank 31, thereby realizing a one-way flow of the lubricating oil between the oil storage tank 31 and the oil filling pipe 321.

[0052] Reference Figure 3 and Fig.10 As shown: the oil injection structure 32 also includes a second automatic valve 325, the two ends of the second automatic valve 325 are respectively connected to the liquid outlet and the end of the liquid guide tube 323, the second automatic valve 325 includes a second valve body 3251, a second partition plate 3252 is arranged inside the second valve body 3251, a plurality of second flow ports are opened on the second partition plate 3252, a second movable rod 3253 slidably connected to the second partition plate 3252 is arranged inside the second valve body 3251, second sealing plates 3254 are arranged at both ends of the second movable rod 3253, a second spring 3255 is sleeved on one end of the second movable rod 3253 facing the oil injection tube 321, and the two ends of the second spring 3255 are respectively abutted against the second sealing plate 3254 and the second partition plate 3252.

[0053] If the oil chamber 121 is connected to the oil filling pipe 321 through the liquid guide pipe 323, the oil filling pipe 321 will generate suction on the lubricating oil in the oil chamber 121 when sucking the lubricating oil in the oil storage tank 31, causing the lubricating oil in the oil chamber 121 to flow back into the oil filling pipe 321. Therefore, a second automatic valve 325 is provided between the liquid guide pipe 323 and the oil filling pipe 321. When the oil filling pipe 321 supplies oil toward the oil chamber 121, the lubricating oil pressure in the oil filling pipe 321 increases, and a thrust is applied to both second sealing plates 3254 away from the oil filling pipe 321. At this time, the second sealing plate 3254 on the side away from the oil filling pipe 321 is separated from the second partition plate 3252, while the second sealing plate 3254 on the other side is The second spring 3255 is compressed, the second circulation port is opened, and the lubricating oil in the oil filling pipe 321 flows to the oil chamber 121 through the second circulation port. On the contrary, when the oil filling pipe 321 draws the lubricating oil in the oil storage tank 31, a negative pressure is generated inside the oil filling pipe 321, which produces a suction effect on the two second sealing plates 3254. With the assistance of the second spring 3255, the second sealing plate 3254 away from the side of the oil filling pipe 321 is in close contact with the second partition plate 3252, closing the second circulation port, effectively preventing the lubricating oil in the oil chamber 121 from flowing back into the oil filling pipe 321 during the suction process of the oil filling pipe 321, thereby realizing a one-way flow of the lubricating oil between the oil chamber 121 and the oil filling pipe 321.

[0054] Reference Figure 3 and Fig.11 As shown: the oil filling structure 32 also includes a sealing structure 326, which is arranged at the oil filling port of the oil storage tank 31. The sealing structure 326 includes a sealing plug 3261 and an air intake filter element 3262. An air intake channel is opened in the middle of the sealing plug 3261, one end of the sealing plug 3261 is threadedly connected to the oil filling port, and the air intake filter element 3262 is arranged at the other end of the sealing plug 3261.

[0055] As the lubricating oil in the oil tank 31 gradually decreases, the air pressure in the tank will drop accordingly. In order to maintain the stability of the air pressure, external air is introduced into the oil tank 31 through the air intake channel in the middle of the sealing plug 3261. However, the external air often contains impurities such as dust. If these impurities enter the oil tank 31 directly, they will seriously affect the purity and lubrication effect of the lubricating oil. Therefore, before the air enters the oil tank 31, it will first be filtered by the air intake filter 3262. The air intake filter 3262 can block and remove dust and other impurities in the air to ensure that only clean air enters the oil tank 31, thereby avoiding the risk of the lubricating oil becoming ineffective due to contamination by impurities.

[0058] S2, the output rod 11 drives the connecting shaft 12 to swing, the connecting shaft 12 drives the guide rod 13 to move, and at the same time the connecting shaft 12 drives the two transmission arm structures 42 to move up and down through the linkage transmission structure 41, and the two transmission arm structures 42 drive the synchronous driving structure 43 to move;

[0059] S3, the synchronous driving structure 43 drives the two oil injection structures 32 to move, and the oil injection structure 32 injects the lubricating oil in the oil storage tank 31 into the oil cavity 121 of the connecting shaft 12, and the lubricating oil enters between the connecting shaft 12 and the guide rod 13 along the oil outlet hole 122 to lubricate the connection between the two;

[0060] S4. When it is necessary to control the amount of lubricating oil entering between the connecting shaft 12 and the guide rod 13, the angle adjustment structure 423 adjusts the angle between the second vertical plate 421 and the first driving plate 422, indirectly controlling the distance that the push rod 322 moves in the oil filling pipe 321, thereby achieving control of the amount of injected lubricating oil.
