Description

Technical Field

[0001] This invention belongs to the field of textile machinery technology, specifically a pressure plate for the needle bed of a Raschel warp knitting machine to prevent cracking. Background Technology

[0002] Raschel warp knitting machines are used to knit warp-knitted fabrics with relatively complex structures, such as curtains, tablecloths, and bedspreads.

[0003] Previously, the pressure plates in Raschel warp knitting machines were prone to breakage during use. Later, the tightening torque of the bolts was reduced to 5 N*m to reduce the pressure on the pressure plates and prevent breakage. However, this caused the groove needles in the groove needle bed to be loose, resulting in skipped stitches and poor fabric quality. To solve this problem, the vulnerable parts of the pressure plates were thickened, and the design of the connection between the pressure plates and the pressure strips was changed. The original design of one pressure plate corresponding to one pressure strip was changed to one pressure strip corresponding to two pressure plates, thereby reducing replacement costs when the pressure plates are damaged.

[0004] In the current technology, although changing the design from one pressure plate to one pressure strip to one pressure strip to two pressure plates can reduce replacement costs, the lack of connection between the two pressure plates reduces the stress on the two pressure plates, making them more prone to damage and resulting in a shorter service life.

[0005] Therefore, the present invention provides a pressure plate for the needle bed of a Raschel warp knitting machine to prevent cracking. Summary of the Invention

[0016] Preferably, the pressure plate body, pressure strip, and pressure block are all injection molded parts, and the pressure plate body, pressure strip, and pressure block are all made of nylon.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The Raschel warp knitting machine anti-crack groove needle bed pressure plate of the present invention, through the insertion rod connecting the two pressure plate bodies, can increase the stress of the two pressure plate bodies, thereby protecting the two pressure plate bodies and extending their service life. When one pressure plate body is damaged, by pulling the first pull rod, the first pull rod drives the insertion rod to slide in the movable hole and disengage the insertion rod from the inside of the other pressure plate, so that the connection between the two pressure plate bodies is lost, and the damaged pressure plate body can be removed and replaced. During the movement of the insertion rod, the fourth spring is compressed, causing the fourth spring to contract and the fourth spring to exert a thrust on the insertion rod. After the damaged pressure plate body is replaced, the first pull rod is released, and under the action of the thrust of the fourth spring, the insertion rod will insert into the inside of the pressure plate body, connecting the two pressure plate bodies and thus increasing the stress of the two pressure plate bodies.

[0019] 2. The anti-crack groove needle bed pressure plate of the Raschel warp knitting machine described in this invention, during the installation of the pressure block, the end of the pressure block corresponding to the pressure strip away from the pressure plate body is moved so that the pressure strip enters the interior of the pressure block. During the movement of the pressure block, the pressure block will contact the semi-circular positioning block and squeeze the semi-circular positioning block, causing the semi-circular positioning block to slide and descend within the telescopic groove, eventually entering the telescopic groove. During the descent of the semi-circular positioning block, it will squeeze the first spring. The first spring will contract under compression and exert a thrust on the semi-circular positioning block. As the pressure block moves, the semi-circular positioning block... When the positioning block is aligned with the fixed groove, the semi-circular positioning block will be lifted and enter the fixed groove under the pushing force of the spring, thus fixing the pressure block after installation. When the pressure block is damaged and needs to be removed and replaced, press the connecting rod to move the connecting rod down. The downward movement of the connecting rod causes the sliding rod to move down, which in turn causes the pressure rod to move down. The downward movement of the pressure rod will squeeze the semi-circular positioning block, causing the semi-circular positioning block to slide down into the telescopic groove. After the semi-circular positioning block has descended into the telescopic groove, pull the pressure block to remove it. This makes the pressure block easy to install and remove.

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] like Figures 1 to 9As shown in the embodiment of the present invention, a pressure plate for a Raschel warp knitting machine with anti-crack groove includes a needle bed body 1. A pressure plate body 11 is symmetrically arranged on one side of the needle bed body 1. Positioning sleeves 12 are slidably connected to the middle portions of the two pressure plate bodies 11. The two pressure plate bodies 11 are fixed to the needle bed body 1 by screws 13. A butterfly spring 14 is provided between the pressure plate bodies 11 and the screws 13. A pressure strip 15 is hinged to the upper side of the two pressure plate bodies 11 near the needle bed body 1. A pressure block is installed on the outer side of the pressure strip 15. 16; Several evenly arranged grooved needle bodies 17 are inserted into the side of the needle bed body 1 near the pressure plate body 11; An installation assembly is provided between the pressure strip 15 and the pressure block 16, and the installation assembly includes a spring 21 and a semi-circular positioning block 22, the semi-circular positioning block 22 being fixed to the upper end of the spring 21; A vibration damping assembly is provided above the needle bed body 1 at the position corresponding to the grooved needle body 17, and the vibration damping assembly is used to dampen and protect the grooved needle body 17; A connecting assembly is provided between the two pressure plate bodies 11, and the connecting assembly includes a spring 5 1. A plug rod 52 is plugged and fixed to one end of spring 4 51. To improve the service life of the two pressure plate bodies 11, a connecting assembly is provided between the two pressure plate bodies 11. The plug rod 52 connecting the two pressure plate bodies 11 can increase the stress of the two pressure plate bodies 11, thereby protecting the two pressure plate bodies 11 and extending their service life. When one of the pressure plate bodies 11 is damaged, by pulling the pull rod 53, the pull rod 53 drives the plug rod 52 to slide in the movable hole 5, and the plug rod 52... By detaching from the other pressure plate, the connection between the two pressure plate bodies 11 is lost, allowing the damaged pressure plate body 11 to be removed and replaced. During the movement of the insertion rod 52, the spring 4 51 is compressed, causing the spring 4 51 to contract and exert a pushing force on the insertion rod 52. After replacing the damaged pressure plate body 11, the pull rod 1 53 is released. Under the pushing force of the spring 4 51, the insertion rod 52 will be inserted into the pressure plate body 11, connecting the two pressure plate bodies 11 and increasing the stress on the two pressure plate bodies 11.

[0034] like Figure 6As shown, the installation assembly includes several telescopic grooves, which are located above the pressure strip 15. A spring 21 is fixedly connected inside the telescopic groove. A semi-circular positioning block 22 is fixedly connected above the spring 21. Several evenly arranged fixing grooves 23 are provided below the pressure block 16 corresponding to the position of the semi-circular positioning block 22, and the upper end of the semi-circular positioning block 22 is located inside the fixing groove 23. When installing the pressure block 16, the middle part of the pressure block 16 is moved to the end of the pressure strip 15 away from the pressure plate body 11, so that the pressure strip 15 enters the interior of the pressure block 16. During the process, the pressure block 16 will contact the semi-circular positioning block 22 and squeeze the semi-circular positioning block 22, causing the semi-circular positioning block 22 to slide down in the telescopic groove and finally enter the telescopic groove. During the descent of the semi-circular positioning block 22, it will squeeze the spring 21. The spring 21 will contract under the compression and give the semi-circular positioning block 22 a thrust. When the pressure block 16 moves so that the semi-circular positioning block 22 is aligned with the fixed groove 23, the semi-circular positioning block 22 will be lifted up and enter the fixed groove 23 under the thrust of the spring 21, thereby completing the installation of the pressure block 16 and fixing it.

[0035] like Figure 1 , Figure 5 and Figure 6 As shown, several evenly arranged connecting holes 3 are provided above the pressure block 16 at the position corresponding to the fixing groove 23; a second spring 31 is fixedly connected inside the connecting hole 3; a first sliding rod 32 is fixedly connected above the second spring 31; a pressure rod 33 is fixedly connected below the first sliding rod 32, and the lower end of the pressure rod 33 is located in the fixing groove 23; a connecting rod 34 is fixedly connected above the first sliding rod 32; when the pressure block 16 is damaged and needs to be removed and replaced, pressing the connecting rod 34 causes the connecting rod 34 to move downward, the downward movement of the connecting rod 34 drives the first sliding rod 32 to move downward, and the downward movement of the first sliding rod 32 drives the pressure rod 33 to move downward. 3. Moving downwards, the pressure rod 33 will press against the semi-circular positioning block 22, causing it to slide down into the telescopic groove. After the semi-circular positioning block 22 has descended into the telescopic groove, the pressure block 16 can be removed by pulling it. During the downward movement of the sliding rod 32, the spring 31 will be pressed, causing it to contract and exert a pushing force on the sliding rod 32. After removing the pressure block 16, the connecting rod 34 will be slowly released. Under the pushing force of the spring 31, the connecting rod 34, the sliding rod 32, and the pressure rod 33 will return to their original positions.

[0036] like Figure 2 and Figure 8As shown, the vibration damping component includes a positioning groove 4, and several positioning grooves 4 are provided. The positioning grooves 4 are located above the needle bed body 1, corresponding to the position of the grooved needle body 17. Symmetrically arranged springs 41 are fixedly connected within the positioning grooves 4. A clamping plate 42 is fixedly connected to the other end of each spring 41, and the grooved needle body 17 is located between two clamping plates 42. A guide plate 43 is fixedly connected to the end of the clamping plate 42 away from the needle bed body 1. When the grooved needle body 17 is inserted into the needle bed body 1, the grooved needle body 17 contacts the guide plate 43 and presses against it, causing the guide plate 43 to... As the guide plate 43 moves, it drives the clamping plate 42 to move. The movement of the clamping plate 42 will compress the spring 41. The spring 41 will contract under compression and give the clamping plate 42 a thrust. After the grooved needle body 17 is inserted into the needle bed body 1, the grooved needle body 17 will be located in the middle of the two clamping plates 42. Under the action of the thrust of the spring 41, the clamping plate 42 will fix the two sides of the grooved needle body 17. When the grooved needle body 17 is working, with the cooperation of the spring 41, it can play a role in damping the grooved needle body 17 and preventing the grooved needle body 17 from breaking.

[0037] like Figure 2 and Figure 8 As shown, a limiting rod 44 is fixedly connected to one end of the clamping plate 42 near the spring 41, and the limiting rod 44 is located inside the spring 41; a limiting groove 45 is opened on the needle bed body 1 corresponding to the position of the limiting rod 44, and the limiting rod 44 is slidably connected in the limiting groove 45; through the limiting rod 44 fixed on the clamping plate 42 and the limiting groove 45 opened on the needle bed body 1, the limiting rod 44 is slidably connected in the limiting groove 45, which can limit the position of the spring 41 and the clamping plate 42 and prevent the spring 41 and the clamping plate 42 from shifting.

[0038] like Figure 1 and Figure 3As shown, a movable hole 5 is provided above one of the pressure plate bodies 11; a spring 4 51 is fixedly connected inside the movable hole 5; a plug rod 52 is fixedly connected to the other end of the spring 4 51, and the plug rod 52 is slidably connected inside the movable hole 5, with one end of the plug rod 52 away from the spring 4 51 inserted into the interior of the other pressure plate body 11; a pull rod 53 is fixedly connected to the end of the plug rod 52 near the spring 4 51 away from the pressure plate body 11; the plug rod 52 connecting the two pressure plate bodies 11 can increase the stress on the two pressure plate bodies 11, thereby protecting the two pressure plate bodies 11 and extending their service life. When the plate body 11 is damaged, by pulling the first pull rod 53, the pull rod 53 moves, causing the insertion rod 52 to slide in the movable hole 5, and causing the insertion rod 52 to disengage from the other pressure plate, so that the connection between the two pressure plate bodies 11 is lost, and the damaged pressure plate body 11 can be removed and replaced. During the movement of the insertion rod 52, the spring 4 51 will be squeezed and compressed, and the spring 4 51 will give the insertion rod 52 a pushing force. After the damaged pressure plate body 11 is replaced, the pull rod 53 is released, and under the action of the pushing force of the spring 4 51, the insertion rod 52 will be inserted into the inside of the pressure plate body 11, connecting the two pressure plate bodies 11.

[0039] like Figure 3 and Figure 9 As shown, a housing 6 is fixedly connected to the upper part of one of the pressure plate bodies 11, corresponding to the middle of the movable hole 5; a spring 61 is fixedly connected inside the housing 6; a sliding rod 62 is fixedly connected to the other end of the spring 61, and the sliding rod 62 is slidably connected inside the housing 6; a triangular block 63 is fixedly connected to the end of the sliding rod 62 away from the housing 6; a pull rod 64 is fixedly connected above the triangular block 63; during the movement of the pull rod 53, it will contact the triangular block 63 and squeeze the triangular block 63. The triangular block 63 will move under the pressure, causing the pull rod 53 to pass over the triangular block 63. The movement of the triangular block 63 will drive the sliding rod 62 to move inside the housing 6. The movement of the sliding rod 62 will squeeze the spring 61, and the spring 61 will be squeezed. The pressure will contract and exert a thrust on the slide bar 2 62. After the pull rod 1 53 passes the triangular block 63, the slide bar 2 62 and the triangular block 63 will return to their original positions under the action of the spring 5 61, thereby fixing the pull rod 1 53, the insert rod 52 and the spring 4 51. This can help when replacing the damaged pressure plate body 11. After the damaged pressure plate body 11 is replaced, pull the pull rod 2 64 to move the triangular block 63 away from the pull rod 1 53. After the triangular block 63 moves away from the pull rod 1 53, the pull rod 1 53, the insert rod 52 and the spring 4 51 lose their fixation. Under the action of the spring 4 51, the insert rod 52 will be inserted into the inside of the pressure plate body 11 to connect the two pressure plate bodies 11.

[0040] like Figure 4 As shown, the pressure strip 15 has symmetrically arranged guide surfaces 81 at the end away from the pressure plate body 11; the pressure block 16 has an arc-shaped surface 8 at the position above the pressure strip 15 in the middle, and the arc-shaped surface 8 cooperates with the semi-circular positioning block 22; the guide surface 81 on the pressure strip 15 makes it easier to install the pressure strip 15 inside the pressure block 16; the arc-shaped surface 8 on the pressure block 16 can squeeze the semi-circular positioning block 22 when it contacts the pressure block 16, so that the semi-circular positioning block 22 can slide into the telescopic groove, thereby cooperating with the semi-circular positioning block 22 to slide and telescopically extend.

[0041] like Figure 1 , Figure 4 and Figure 5 As shown, a protective pad 1 is fixedly attached to the side of the pressure block 16 away from the pressure plate body 11; a protective pad 2 is fixedly attached to the side of the needle bed body 1 above the pressure block 16, and the grooved needle body 17 is located between the protective pad 1 and the protective pad 2; the protective pad 1 and the protective pad 2 are made of high-density polyethylene material; the protective pad 1 fixed on the pressure block 16 and the protective pad 2 fixed on the needle bed body 1 can protect the grooved needle body 17. High-density polyethylene material has the advantages of good wear resistance, good electrical insulation, good toughness and cold resistance, and is non-toxic and odorless, which can improve the service life of the protective pad 1 and the protective pad 2.

[0042] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, the pressure plate body 11, pressure strip 15 and pressure block 16 are all injection molded parts, and the pressure plate body 11, pressure strip 15 and pressure block 16 are all made of nylon. Nylon material has the advantages of high strength, good toughness, high compressive strength, high tensile strength, outstanding fatigue resistance and corrosion resistance, which can improve the service life of the pressure plate body 11, pressure strip 15 and pressure block 16.

[0043] Working principle:

[0044] The insertion rod 52 connecting the two pressure plate bodies 11 increases the stress on the two pressure plate bodies 11, thereby protecting them and extending their service life. When one pressure plate body 11 is damaged, pulling the pull rod 53 causes the insertion rod 52 to slide within the movable hole 5, disengaging it from the other pressure plate and breaking the connection between the two pressure plate bodies 11. This allows the damaged pressure plate body 11 to be removed and replaced. During the movement of the insertion rod 52, [the following text is incomplete and likely refers to a separate process:] ... Spring 4 51 is compressed, causing it to contract and exert a pushing force on the insertion rod 52. After replacing the damaged pressure plate body 11, the pull rod 1 53 is released. Under the pushing force of spring 4 51, the insertion rod 52 is inserted into the pressure plate body 11, connecting the two pressure plate bodies 11 and increasing their stress. When installing the pressure block 16, the end of the pressure block 16 corresponding to the pressure strip 15 away from the pressure plate body 11 is moved to allow the pressure strip 15 to enter the interior of the pressure block 16. During the movement, the pressure block 16 contacts the semi-circular positioning block 22 and presses it, causing the semi-circular positioning block 22 to slide and descend within the telescopic groove, eventually entering the groove. As the semi-circular positioning block 22 descends, it presses the spring 21, causing the spring 21 to contract and exert a pushing force on the semi-circular positioning block 22. When the pressure block 16 moves to position the semi-circular positioning block 22 opposite the fixing groove 23, the pushing force of the spring 21 causes the semi-circular positioning block 22 to rise and enter the fixing groove 23. Within 3, the pressure block 16 is fixed after installation. When the pressure block 16 is damaged and needs to be removed and replaced, press the connecting rod 34 to move the connecting rod 34 down. The downward movement of the connecting rod 34 causes the sliding rod 32 to move down, which in turn causes the pressure rod 33 to move down. The downward movement of the pressure rod 33 will squeeze the semi-circular positioning block 22, causing the semi-circular positioning block 22 to slide down into the telescopic groove. After the semi-circular positioning block 22 has descended into the telescopic groove, pull the pressure block 16 to remove it. This makes the pressure block 16 easy to install and remove.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
