Description

Technical Field

[0001] The utility model relates to the technical field of jacquard machine cylinders, and specifically relates to an improved cylinder applied to a high-density coral fleece jacquard machine. Background Technique

[0002] As a textile tool, the jacquard machine is an important invention in ancient China. Archaeological evidence shows that from the silk fabric traces preserved on the bronze wares in the Yin Ruins tombs in Anyang, Henan, there are not only plain-weave silk fabrics but also jacquard rhombus-patterned silk fabrics. This indicates that as early as the Shang Dynasty in China, general looms could only weave plain fabrics, and fabrics with complex patterns could only be woven by jacquard machines. In the process of towel production, a jacquard machine is needed to create patterns on the towel surface.

[0003] The utility model patent application document with the publication number of "CN217839308U" discloses a jacquard machine cylinder, including a needle plate. A plurality of cylinders are clamped on the needle plate. The needle plate is provided with a plurality of fixing structures. The fixing structures include two sliding rods. A plurality of sliding rods are slidably connected to the needle plate. The sliding rods are fixedly connected with connecting blocks. A clamping block is slidably connected to the connecting block. The two clamping blocks are clamped with the cylinder. A first return spring is abutted between the connecting block and the clamping block. A rack is fixedly connected to the sliding rod. A plurality of gears are rotatably connected to the needle plate. The two sides of the gear are respectively meshed with the two racks. A second return spring is fixedly connected between one of the sliding rods and the needle plate. The needle plate is provided with a plurality of positioning structures; it is convenient for the quick installation and disassembly of the cylinder, and the cylinder can also be disassembled in the event of a power failure, avoiding dependence on electricity, and the sudden drop of the cylinder can be avoided during the disassembly process, preventing the cylinder from dropping and hitting the equipment, resulting in damage to the equipment and the cylinder.

[0004] The jacquard machine cylinder disclosed in the above document has the following defects: This technical solution cannot buffer the vertical impact force generated by the cylinder during use, resulting in the situation where the cylinder hits and damages the equipment or itself during use.

[0005] It can be seen from this that the existing jacquard machine cylinders do not have good buffer components, and it is necessary to improve the existing deficiencies by providing an improved cylinder applied to a high-density coral fleece jacquard machine. Utility Model Content

[0006] The purpose of the present utility model is to provide an improved cylinder applied to a high-density coral fleece jacquard machine to solve the problems raised in the above background technique.

[0007] To solve the above technical problems, the present utility model is realized through the following technical solutions:

[0008] The utility model relates to an improved needle cylinder applied to a high-density coral fleece jacquard machine, which comprises a needle disc body. A fixed sleeve is arranged on the lower surface of the needle disc body. A groove is arranged at the inner top of the fixed sleeve. A buffer assembly is arranged inside the groove. The buffer assembly comprises a slide rod, a limiting plate, a first spring, a resisting plate and a buffer plate. The limiting plate is fixedly installed at the inner top of the fixed sleeve. The inner wall of the limiting plate is slidably connected with the slide rod. The slide rod extends into the groove. The first spring is fixedly installed on the lower surface of the limiting plate. The end of the slide rod far away from the groove is fixedly installed with the resisting plate. The resisting plate is connected with the first spring. The buffer plate is fixedly installed on the lower surface of the resisting plate.

[0009] Furthermore, clamping blocks are fixedly installed on the inner wall of the fixed sleeve. The number of the clamping blocks is fixed at two. Arc surfaces are arranged on the outer surfaces of the clamping blocks. An arc surface clamping groove is arranged on the lower surface of the clamping blocks.

[0010] Furthermore, a needle cylinder is arranged inside the fixed sleeve. Sliding grooves are arranged on the circumferential side surface of the needle cylinder. The number of the sliding grooves is fixed at two.

[0011] Furthermore, guiding grooves are arranged on the circumferential side surface of the needle cylinder. The number of the guiding grooves is fixed at two. The guiding grooves are communicated with the sliding grooves. Installation grooves are arranged on the side surface of the needle cylinder. The number of the installation grooves is fixed at two. The installation grooves are communicated with the guiding grooves.

[0012] Furthermore, clamping assemblies are fixedly installed on the inner walls of the installation grooves. Each clamping assembly comprises a containing shell, a second spring, a supporting plate, a supporting column, an installation plate and an arc surface clamping block. The containing shell is fixedly installed on the inner wall of the installation groove. The second spring is fixedly installed at the inner bottom of the containing shell. One end of the second spring is fixedly installed with the supporting plate. The supporting plate is connected with the containing shell. The supporting column is fixedly installed on the upper surface of the supporting plate. The installation plate is fixedly installed on the upper surface of the supporting column. The arc surface clamping block is fixedly installed on the upper surface of the installation plate. The arc surface clamping block is clamped with the arc surface clamping groove.

[0013] Furthermore, a connecting plate is fixedly installed on the circumferential side surface of the fixed sleeve. A connecting bolt is threadedly connected to the inner wall of the connecting plate. The connecting bolt is threadedly connected with the needle disc body.

[0014] The utility model has the following beneficial effects:

[0015] (1) In the present utility model, the syringe is squeezed inwardly, so that the clamping block squeezes the arc-shaped block. The arc-shaped block is squeezed and moved, causing the support column to drive the support plate to squeeze the second spring. The first shock absorption is completed through the second spring. At the same time, the syringe squeezes the buffer plate inwardly. The buffer plate drives the abutting plate to move. The abutting plate drives the sliding rod to slide inside the limiting plate towards the inside of the groove, so that the abutting plate squeezes the first spring. The syringe is secondarily shock-absorbed through the elastic mechanism of the first spring, avoiding the situation that the equipment or itself is damaged by impact when the syringe is in use.

[0016] (2) In the present utility model, the two chutes on the syringe are aligned with the two clamping blocks for installation. When the clamping block is installed at the top of the chute, the syringe is rotated so that the clamping block enters the inside of the guiding groove. When the clamping block rotates to one end of the guiding groove, the arc-shaped surface contacts the arc-shaped block and squeezes the arc-shaped block downward, so that the second spring contracts, causing the support column to drive the mounting plate and the arc-shaped block to move downward. Then, the syringe is continuously rotated so that the arc-shaped block is clamped tightly inside the arc-shaped chute, and the installation can be completed. While achieving installation and fixation, the structure is simple and the production cost is reduced.

[0017] Of course, when implementing any product of the present utility model, it is not necessarily required to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

The buffer plate 305 is fixedly installed on the lower surface of the baffle plate 304.

[0030] Clamping blocks 4 are fixedly installed on the inner wall of the fixed sleeve 2. The number of the clamping blocks 4 is fixed at two. Arc-shaped surfaces 402 are provided on the outer surfaces of the clamping blocks 4. Arc-shaped card slots 401 are provided on the lower surfaces of the clamping blocks 4.

[0031] A syringe barrel 5 is provided inside the fixed sleeve 2. Slide grooves 6 are provided on the circumferential side of the syringe barrel 5. The number of the slide grooves 6 is fixed at two.

[0032] The circumferential side surface of the syringe barrel 5 is provided with guiding grooves 601. The number of the guiding grooves 601 is fixed at two. The guiding grooves 601 communicate with the sliding grooves 6. The side surface of the syringe barrel 5 is provided with mounting grooves 602. The number of the mounting grooves 602 is fixed at two. The mounting grooves 602 communicate with the guiding grooves 601.

[0033] The inner walls of the mounting grooves 602 are fixedly installed with clamping components 7. The clamping components 7 include accommodating shells 701, second springs 702, support plates 703, support columns 704, mounting plates 705 and arc-shaped clamping blocks 706. The inner walls of the mounting grooves 602 are fixedly installed with accommodating shells 701. The inner bottom of the accommodating shells 701 is fixedly installed with second springs 702. One end of each second spring 702 is fixedly installed with a support plate 703. The support plate 703 is connected with the accommodating shell 701. The upper surface of the support plate 703 is fixedly installed with a support column 704. The upper surface of the support column 704 is fixedly installed with a mounting plate 705. The upper surface of the mounting plate 705 is fixedly installed with an arc-shaped clamping block 706. The arc-shaped clamping block 706 is clamped with the arc-shaped clamping groove 401.

[0034] The circumferential side surface of the fixed sleeve 2 is fixedly installed with a connecting plate 8. The inner wall of the connecting plate 8 is threadedly connected with a connecting bolt 9. The connecting bolt 9 is threadedly connected with the needle disc body 1.

[0035] During use, first connect the connecting bolt 9 into the inside of the connecting plate 8 and the needle disc body 1, so as to fix the fixed sleeve 2 on the outer surface of the needle disc body 1. Then align the two sliding grooves 6 on the syringe barrel 5 with the two clamping blocks 4 for installation. When the clamping block 4 is installed at the top of the sliding groove 6, rotate the syringe barrel 5 so that the clamping block 4 enters the inside of the guiding groove 601. When the clamping block 4 rotates to one end of the guiding groove 601, the arc-shaped surface 402 contacts the arc-shaped clamping block 706 and presses the arc-shaped clamping block 706 downward, so that the second spring 702 contracts and the support column 704 drives the mounting plate 705 and the arc-shaped clamping block 706 to move downward. Then continuously rotate the syringe barrel 5 so that the arc-shaped clamping block 706 is clamped tightly inside the arc-shaped clamping groove 401 to complete the installation. While achieving installation and fixation, the structure is simple and the production cost is reduced. Then when the syringe barrel 5 is in use, squeeze it inward so that the clamping block 4 presses the arc-shaped clamping block 706. The arc-shaped clamping block 706 is squeezed and moved, and the support column 704 drives the support plate 703 to press the second spring 702. The first shock absorption is completed through the second spring 702. At the same time, the syringe barrel 5 squeezes the buffer plate 305 inward. The buffer plate 305 drives the abutting plate 304 to move. The abutting plate 304 drives the sliding rod 301 to slide inside the inner wall of the limiting plate 302 into the inside of the groove 201, so that the abutting plate 304 presses the first spring 303. The second shock absorption of the syringe barrel 5 is carried out through the elastic mechanism of the first spring 303, avoiding the situation that the syringe barrel 5 damages the equipment or itself during use. When disassembling, just rotate the syringe barrel 5 in the reverse direction.
