Description

Technical Field

[0001] This invention relates to the field of vibration reduction technology, specifically to a vibration reduction structure for a warp knitting machine. Background Technology

[0002] Vibration during warp knitting machine operation mainly stems from the motion characteristics of its complex mechanisms under high-speed operation. For example, the periodic impacts and inertial forces generated by components such as the main shaft of the loop forming mechanism and the guide bar traverse system during high-speed reciprocating motion become particularly prominent when the mechanism motion signals and structural vibration signals overlap. The harm caused by this vibration is multifaceted. On the one hand, it directly affects product quality, potentially causing the guide bar to rub against the yarn, resulting in uneven fabric density or disordered patterns. On the other hand, it damages the equipment itself, accelerating the wear of machine parts, reducing processing accuracy, shortening the equipment's service life, and generating noise, which can harm the physical and mental health of operators.

Detailed Implementation

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1, referring to Figures 1 to 7 This is the first embodiment of the present invention, which provides a shock-absorbing structure for a warp knitting machine, capable of achieving shock absorption and buffering protection for the warp knitting machine, including: Warp knitting machine body 1, mounting plate 11 provided on the side of warp knitting machine body 1; and, The vibration damping mechanism 2 includes a primary vibration damping component 21 disposed outside the mounting plate 11 and a secondary vibration damping component 22 disposed outside the primary vibration damping component 21; and, The primary damping assembly 21 includes a connecting plate 2101 disposed on the end face of the mounting plate 11, a mounting base 2103 disposed on the end face of the connecting plate 2101, a first limiting sleeve 2104 disposed on the end face of the mounting base 2103, a second limiting sleeve 2105 sleeved inside the first limiting sleeve 2104, a top plate 2107 disposed at the end of the second limiting sleeve 2105, and a first spring 2106 disposed between the sides of the first limiting sleeve 2104 and the second limiting sleeve 2105 that are close to each other and between the sides of the mounting base 2103 and the top plate 2107 that are close to each other; and, The secondary damping assembly 22 includes a base plate 2201 disposed on the end face of the connecting plate 2101, a support rod 2206 disposed on the end face of the base plate 2201, a sliding block 2205 sleeved on the outer wall of the support rod 2206, a second spring 2210 disposed on the side of the sliding block 2205, an externally threaded tube 2215 disposed on the outer wall of the sliding block 2205, an internally threaded tube 2216 sleeved on the outer wall of the externally threaded tube 2215, and a sleeve plate 2219 sleeved on the outer wall of the externally threaded tube 2215; wherein, The mounting plates 11 on both sides of the bottom of the warp knitting machine body 1 serve as a connection to the shock absorption mechanism 2. The shock absorption mechanism 2 is divided into two levels, which can complete two-level shock absorption and achieve better shock absorption of the warp knitting machine body 1.

[0028] Specifically, there are two support rods 2206, which are mirror-symmetrical about the vertical line of the base plate 2201. There are two sliding blocks 2205, which are sleeved on the outer walls of the two support rods 2206. One of the sliding blocks 2205 is connected to the end of the external threaded tube 2215. The second spring 2210 is located on the side of the sleeve plate 2219 and the other sliding block 2205.

[0029] Furthermore, a second support frame 2209 is provided on the side of the sliding block 2205 away from the second spring 2210, a connecting block 2208 is provided on the side of the second support frame 2209 away from the sliding block 2205, and a first support frame 2207 is provided on the other side of the connecting block 2208. The end of the first support frame 2207 is connected to the end face of the connecting plate 2101.

[0030] Furthermore, the perpendicular line of the connecting plate 2101 is the same as the perpendicular line of the base plate 2201. There are two of each of the first support frame 2207, the connecting block 2208, and the second support frame 2209, and they are mirror-symmetrical about the perpendicular line of the connecting plate 2101.

[0031] In summary, when in use, the warp knitting machine body 1 is a common knitting machine. It feeds one or more parallel warp yarns into all the knitting needles of the machine at the same time, and allows each yarn to form one or more loops along the longitudinal warp direction of the fabric during lateral movement, thereby knitting into fabric. Mounting plates 11 are fixedly connected to the bottom of both sides of the warp knitting machine body 1, and shock absorption mechanisms 2 are provided below the two mounting plates 11 for the warp knitting machine body 1 to perform shock absorption operation. The damping mechanism 2 is further divided into a primary damping component 21 and a secondary damping component 22, which together form the two-stage damping of the device. By using the connecting plate 2101 in the primary shock absorption assembly 21 as support for the two mounting bases 2103, and placing the mounting plate 11 above the primary shock absorption assembly 21, the warp knitting machine body 1 can be prevented from tilting to one side at a large angle. The mounting bases 2103 are installed on the connecting plate 2101 using bolts or similar methods. A first limiting sleeve 2104 is fixedly connected to the top of the mounting base 2103, and a second limiting sleeve 2105 is slidably connected to the inner wall of the first limiting sleeve 2104. The outer wall of the second limiting sleeve 2105 is slidably connected to the inner wall of the first limiting sleeve 2104, thereby effectively ensuring that the top plate 2107, which is fixedly connected to the upper end face of the mounting base 2103, moves straight up and down during shock absorption, avoiding the problem of tilting and swaying. Because the second limiting sleeve 2105 draws and compresses the gas inside between the second limiting sleeve 2105 and the first limiting sleeve 2104 during its up-and-down movement, a venting threaded groove 2111 is provided between the sides of the first limiting sleeve 2104 and the second limiting sleeve 2105 that are close to each other. The threaded shape of 211 facilitates the outward circulation of internal gas as the top plate 2107 moves downward. Since the primary damping component 21 is the main damping component of the device and experiences the most damping cycles, it avoids generating excessive heat during friction between the outer wall of the second limiting sleeve 2105 and the first limiting sleeve 2104, thus reducing the problem of high temperature causing significant losses. A first spring 2106 is provided between the top plate 2107 and the mounting base 2103. The elastic potential energy of the first spring 2106 effectively absorbs vibrations, and the first spring 2106 allows the top plate 2107 to move up and down during damping. Therefore, in conjunction with the exhaust threaded groove 2111, it facilitates the entry of gas into the interior of the first limiting sleeve 2104 and the second limiting sleeve 2105, thereby effectively cooling the gas flow and reducing losses. Through the arranged secondary shock-absorbing assembly 22, the bottom plate 2201 in the secondary shock-absorbing assembly 22 serves as the bottom support of the device, and the two support rods 2206 can be supported by the bottom plate 2201. The two support rods 2206 are in a "匚"-shape, and the two sliding blocks 2205 can be supported by the support rods 2206. When the two sliding blocks 2205 move, they can only approach or move away from each other, and do not perform other movements. When the two sliding blocks 2205 approach each other, they will squeeze the second spring 2210, and since the second spring 2210 has a certain elastic potential energy, shock absorption can be completed again. Through an externally threaded pipe 2215 fixedly connected to the side of one of the two sliding blocks 2205 that faces the other sliding block 2205, since the outer wall of the externally threaded pipe 2215 is threadedly connected with the inner wall of the internally threaded pipe 2216, the sleeve plate 2219 can be squeezed by rotating the internally threaded pipe 2216, and then the second spring 2210 can be squeezed through the sleeve plate 2219, so the elastic potential energy can be adjusted. The first support frames 2207 on both sides are respectively fixedly connected to both sides of the lower end face of the connecting plate 2101, and connection blocks 2208 are movably sleeved at the bottoms of the two first support frames 2207. The other ends of the two connection blocks 2208 are both movably sleeved with second support frames 2209, and the two second support frames 2209 are fixedly connected to the sides of the two sliding blocks 2205 that are away from each other, thereby serving as the support for the connecting plate 2101; Through the above arrangement, the primary shock-absorbing assembly 21 can perform primary buffering on the vibration generated by the warp knitting machine body 1 during use, and the vibration that is not completely filtered by the primary shock-absorbing assembly 21 is then subjected to secondary shock absorption through the secondary shock-absorbing assembly 22, which can achieve a better shock absorption effect with better stability, so that the service life of the warp knitting machine body 1 is also longer.

[0032] Example 2, reference Figures 1 to 7 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a structural optimization of the primary shock-absorbing assembly to solve the problem of poor buffering effect. A first rubber pad 2102 is provided on the end face of the mounting base 2103 close to the connecting plate 2101, a second rubber pad 2108 is provided on the end face of the top plate 2107 close to the mounting plate 11, a threaded rod 2109 is provided on the end face of the top plate 2107 close to the mounting plate 11, the threaded rod 2109 penetrates the inside of the mounting plate 11 and extends to the other side, and a nut 2110 is threadedly connected to the outer wall of the threaded rod.

[0033] Specifically, a first sliding rod 2112 is provided on the end face of the top plate 2107 near the mounting base 2103, and a first piston 2114 is provided at the end of the first sliding rod 2112. A first buffer tube 2113 is provided on the end face of the mounting base 2103 near the top plate 2107. The outer wall of the first piston 2114 is sealed and sleeved with the inner wall of the first buffer tube 2113. A second piston 2115 is sealed and sleeved inside the first buffer tube 2113.

[0034] Furthermore, there is a high-pressure air chamber between the second piston 2115 and the mounting base 2103 on the side that are close to each other, and a high-pressure oil chamber between the second piston 2115 and the first piston 2114 on the side that are close to each other. There are two mounting bases 2103, which are mirror-symmetrical about the vertical line of the connecting plate 2101.

[0035] In summary, during use, the first rubber pad 2102 placed on the lower end face of the mounting base 2103 provides a certain buffer between the mounting base 2103 and the connecting plate 2101, and also serves as sound insulation. At the same time, the second rubber pad 2108 is fixedly connected to the upper end face of the top plate 2107, and the second rubber pad 2108 also serves as a sound insulation buffer between the top plate 2107 and the mounting plate 11. The threaded rod 2109 is provided on the upper end face of the second rubber pad 2108, which passes through the mounting plate 11 and extends to the upper end face of the mounting plate 11. The nut 2110 is connected to the outer wall of the nut 2110 by thread, which facilitates the good fixation of the mounting plate 11 and the top plate 2107. By fixing a first sliding rod 2112 to the lower end face of the top plate 2107, and fixing a first buffer tube 2113 to the upper end face of the mounting base 2103, by passing the lower end of the first sliding rod 2112 through the first buffer tube 2113 and extending into the interior of the first buffer tube 2113, and fixing a first piston 2114 thereon, while the outer wall of the first piston 2114 slides in a sealed manner with the inner wall of the first buffer tube 2113, while a second piston 2115 slides in a sealed manner with the inner wall of the first buffer tube 2113, and damping oil is placed in the high-pressure oil chamber between the sides of the first piston 2114 and the second piston 2115 that are close to each other, and high-pressure gas is injected into the high-pressure air chamber between the sides of the second piston 2115 and the mounting base 2103 that are close to each other, the top plate 2107 can achieve a damping effect when moving up and down, and with the elastic potential energy of the first spring 2106, the shock absorption and buffering effect can be better achieved.

[0036] Example 3, referring to Figures 1 to 7This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides structural optimization of the secondary damping component, which solves the problems of poor secondary buffering and unadjustable potential energy. A third rubber pad 2202 is provided on the side of the base plate 2201 away from the support rod 2206. A first limiting arc plate 2203 is provided on the end face of the connecting plate 2101, and a second limiting arc plate 2204 is provided on the end face of the connecting plate 2101. The second limiting arc plate 2204 and the first limiting arc plate 2203 are in contact with each other on the side that are close to each other. A steel ball group 2218 is embedded in the side of the internal threaded tube 2216 near the sleeve plate 2219. A push bar 2217 is provided on the outer wall of the internal threaded tube 2216.

[0037] Specifically, a second buffer tube 2211 is provided on the side of one of the sliding blocks 2205 away from the second support frame 2209, and a third piston 2213 is sealed inside the second buffer tube 2211. A second sliding rod 2212 is provided on the side of the other sliding block 2205 away from the second support frame 2209, and the second sliding rod 2212 passes through one end of the interior of the second buffer tube 2211 and is provided with a fourth piston 2214.

[0038] Furthermore, the third piston 2213 is located between the fourth piston 2214 and one of the sliding blocks 2205 on one side. The side of the fourth piston 2214 and the third piston 2213 that are close to each other is the high-pressure oil chamber, and the side of the third piston 2213 and one of the sliding blocks 2205 that are close to each other is the high-pressure gas chamber.

[0039] In summary, during use, the third rubber pad 2202 is provided on the lower end face of the base plate 2201, so when the shock absorption mechanism 2 is placed on the ground, it can buffer and avoid noise. The first limiting arc plate 2203 is fixedly connected to both sides of the upper end face of the base plate 2201, and the second limiting arc plate 2204 is fixedly connected to both sides of the lower end face of the connecting plate 2101. The outer wall of the second limiting arc plate 2204 contacts the inside of the first limiting arc plate 2203, so that the first limiting arc plate 2203 and the second limiting arc plate 2204 can only move up and down with the connecting plate 2101 and will not swing left and right. By fixing a pusher bar 2217 to the outer wall of the internally threaded tube 2216, the pusher bar 2217 facilitates the rotation of the internally threaded tube 2216 by the operator, avoiding the problem that the outer wall of the internally threaded tube 2216 is too smooth to rotate. At the same time, a groove is opened on the side of the internally threaded tube 2216 near the sleeve plate 2219 to prevent the steel ball assembly 2218 from being placed inside the groove on the side of the internally threaded tube 2216 near the sleeve plate 2219. This reduces the friction between the sleeve plate 2219 and the internally threaded tube 2216 and also prevents the sleeve plate 2219 from rotating when the internally threaded tube 2216 is rotated, thus affecting the second spring 2210. With this design, only the second spring 2210 is compressed, and the second spring 2210 is not rotated and twisted. By fixing the second sliding rod 2212 to one side of the externally threaded tube 2215 and fitting the externally threaded tube 2215 onto the outer wall of the second sliding rod 2212, fixing one end of the second buffer tube 2211 to one side of another sliding block 2205, sealing the sliding of the fourth piston 2214 by passing one end of the second sliding rod 2212 through the second buffer tube 2211 and extending into the interior of the second buffer tube 2211 and fixing the end to the inner wall of the second buffer tube 2211, sealing the sliding of a third piston 2213 through the interior of the second buffer tube 2211, and adding damping oil to the high-pressure oil chamber between the fourth piston 2214 and the third piston 2213, while injecting high-pressure gas into the high-pressure air chamber between the third piston 2213 and the sliding block 2205, the two sliding blocks 2205 can achieve good damping during sliding, and with the second spring 2210, better secondary shock absorption can be achieved.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
