Description

Technical Field

[0001] This application relates to the field of irregular reeds for air-jet looms, and more particularly to a processing device for irregular reeds for air-jet looms. Background Technology

[0002] Air-jet looms primarily employ a weft insertion method consisting of a main nozzle, an auxiliary nozzle, and a special-shaped reed. The special-shaped reed is a specialized reed used in air-jet looms, where the auxiliary nozzle relays the weft insertion. Like a regular reed, it determines the warp yarn arrangement and drives the weft yarn into the weft hole. The special-shaped reed integrates the airflow diffuser (pipe plate) with the reed itself. The teeth of the special-shaped reed are humped, with the airflow channel (reed groove) between the two humps. During weft insertion, the main airflow and the auxiliary airflow converge with the airflow within the reed groove of the special-shaped reed, forming a combined airflow that meets the requirements of the weft insertion process. The weft yarn advances along the reed groove with the airflow.

[0003] Due to the requirements of the working environment, irregularly shaped reeds need to have a certain degree of wear resistance and strength. In the existing technology, TiAlN and DLC coatings are generally applied to the surface of irregularly shaped reeds to enhance their wear resistance and strength. Before applying the above coatings, the irregularly shaped reeds need to be surface treated. Currently, the surface treatment of irregularly shaped reeds is generally done manually, which results in low processing efficiency. Summary of the Invention

[0004] To improve the efficiency of surface treatment of irregularly shaped reeds, this application provides a processing device for irregularly shaped reeds on an air-jet loom.

[0005] The processing equipment for irregularly shaped reeds on an air-jet loom provided in this application adopts the following technical solution:

[0006] A processing device for irregularly shaped reeds on an air-jet loom includes a stamping device, a horizontal conveying device, a side grinding device, a lower surface grinding device, and an upper surface grinding device. The stamping device is used to stamp irregularly shaped reeds from a steel strip. The side grinding device includes a side grinding seat with a vertically formed hole for the irregularly shaped reed to pass through vertically. A vertical grinding layer is provided on the sidewall of the vertically formed hole, and the vertical grinding layer is used to grind the sidewall of the irregularly shaped reed. The horizontal conveying device is used to horizontally convey the stamped irregularly shaped reed to the bottom of the side grinding seat. The lower surface grinding device includes a first conveying mechanism and a lower surface grinding mechanism. The upper surface grinding device includes... The first conveying mechanism includes a lifting assembly and a rotating conveying assembly for driving the lifting assembly to rotate horizontally. The lifting assembly is used to drive the irregularly shaped reed to rise and fall vertically. When the lifting assembly drives the irregularly shaped reed to rise vertically through the vertical hole, the vertical grinding layer grinds the side of the irregularly shaped reed. The rotating conveying assembly is used to move the irregularly shaped reed from the horizontal conveying device to the second conveying mechanism, and during this process, the lower surface grinding mechanism grinds the lower surface of the irregularly shaped reed. The second conveying mechanism drives the irregularly shaped reed horizontally away from the rotating conveying assembly, and during this process, the upper surface grinding mechanism grinds the upper surface of the irregularly shaped reed.

[0007] By adopting the above technical solution, the stamping device stamps out irregularly shaped reeds from the steel strip. Then, the irregularly shaped reeds are horizontally conveyed by the horizontal conveying device to the bottom of the side grinding seat. Next, the lifting component drives the irregularly shaped reeds to rise. During this process, they pass vertically through the vertical perforation. The vertical grinding layer grinds the side of the irregularly shaped reeds. Then, the rotating conveying component brings the irregularly shaped reeds to the second conveying mechanism. During this process, the lower surface grinding mechanism grinds the lower surface of the irregularly shaped reeds. Finally, the second conveying mechanism drives the irregularly shaped reeds to move horizontally. During this process, the upper surface grinding mechanism grinds the upper surface of the irregularly shaped reeds. In this way, the surface treatment of the irregularly shaped reeds is completed during the material discharge process, without the need for manual intervention, and the surface treatment efficiency is high.

[0008] Optionally, the stamping device includes a stamping frame, a lower die fixed to the stamping frame, an upper die vertically raised and lowered above the lower die, and a driving component for driving the upper die vertically raised and lowered; the lower die has a through-hole for mates with the irregularly shaped reed; the bottom of the stamping frame has a blanking hole with openings at the top and bottom for mates with the stamping hole; the upper die includes a stamping die head for mates with the stamping hole; the horizontal conveying device includes a cylindrical annular horizontal conveying base, a cylindrical annular horizontal conveying ring coaxially rotatably connected to the top of the horizontal conveying base, and a horizontal transmission mechanism for driving the horizontal conveying ring to rotate; a pair of evenly distributed horizontal conveying placement slots for the irregularly shaped reed to enter vertically are formed on the upper surface of the horizontal conveying ring; one horizontal conveying placement slot is located directly below the blanking hole, and the other horizontal conveying placement slot is located directly below the vertical through-hole.

[0009] By adopting the above technical solution, the driving component drives the upper die to descend, so that the stamping die head cooperates with the stamping forming hole to stamp out the irregular reed. Then, the irregular reed falls along the stamping forming hole and the blanking hole until it falls into the horizontal conveying placement groove. Then, the horizontal transmission mechanism drives the horizontal conveying ring to rotate, so that the irregular reed reaches directly below the vertical through hole, which facilitates the discharge and conveying of the irregular reed.

[0010] Optionally, the horizontal conveying placement groove is an isosceles trapezoidal shape; the horizontal conveying placement groove is radially perpendicular to the horizontal conveying ring and its short side is located outside its long side; the length of the short side of the horizontal conveying placement groove is the same as the length of the irregular reed and the short side of the horizontal conveying placement groove is far away from the opening of the irregular reed; a pair of circumferentially uniform horizontal pushing components are provided on the horizontal conveying ring; the horizontal pushing components correspond one-to-one with the horizontal conveying placement groove; the horizontal pushing components are used to push the irregular reed and make the end face of the irregular reed away from the opening abut against the short side of the horizontal conveying placement groove.

[0011] By adopting the above technical solution, the horizontal conveying placement groove is larger than the size of the irregular reed, which facilitates the irregular reed entering the horizontal conveying placement groove. Then, the horizontal pushing component drives the irregular reed to move horizontally. During this process, the two inclined surfaces of the horizontal conveying placement groove guide the irregular reed. Finally, the end face of the irregular reed away from its opening abuts against the short side of the horizontal conveying placement groove, which helps the irregular reed reach the accurate position.

[0012] Optionally, a horizontal guide groove for horizontal movement of the steel strip is formed on the upper end surface of the stamping forming hole; the stamping forming hole is located on the bottom surface of the horizontal guide groove; the upper die also includes an upper die support plate and a pair of pressure blocks; the stamping die head is fixed on the lower end surface of the upper die support plate; the pair of pressure blocks are distributed along the moving direction of the steel strip and located on both sides of the stamping die head; the pressure blocks are vertically and elastically lifted and lowered on the upper die support plate.

[0013] By adopting the above technical solution, the horizontal guide groove restricts the steel strip from moving along its width direction, and a pair of pressure blocks restrict the steel strip from moving up and down. This maintains the accuracy of the steel strip's position, which is conducive to the smooth progress of subsequent stamping and improves the quality of stamping.

[0014] Optionally, the lifting assembly includes a lifting member and a lifting drive member for driving the lifting member to move vertically upwards; the lifting member includes a pair of lifting pins that cooperate with the vertical through hole; the pair of lifting pins are evenly distributed around the rotation center axis of the rotating conveying assembly; an electromagnet is provided at the bottom of the lifting pin; the electromagnet is used to attract irregularly shaped reeds.

[0015] By adopting the above technical solution, the electromagnet generates a magnetic force to hold the irregularly shaped reed, which is simple in structure and facilitates the movement of the irregularly shaped reed.

[0016] Optionally, the lower surface grinding mechanism includes a fan-shaped lower grinding seat; the rotation center axis of the lower grinding seat is collinear with the rotation center axis of the rotating conveying assembly; when the irregular reed is driven to rotate by the rotating conveying assembly, the lower grinding seat is used to grind the lower surface of the irregular reed.

[0017] By adopting the above technical solution, during the rotation of the irregularly shaped reed by the rotating conveyor assembly, the lower grinding seat grinds the lower surface of the irregularly shaped reed. This does not affect the conveying of the irregularly shaped reed and can simultaneously complete the grinding of the lower surface of the irregularly shaped reed, resulting in high grinding efficiency.

[0018] Optionally, the lower surface grinding mechanism further includes a lower surface grinding lifting assembly; the lower surface grinding lifting assembly is used to drive the lower grinding seat to move vertically up and down.

[0019] By adopting the above technical solution, the lower surface grinding lifting component drives the lower grinding seat to rise and fall vertically, which facilitates the maintenance of the lower grinding seat. At the same time, after the lower grinding seat is worn to a certain extent, it can be raised to avoid affecting the smooth progress of subsequent grinding.

[0020] Optionally, the second conveying mechanism includes a conveying support base and a conveying drive assembly for driving the conveying support base to move horizontally; the conveying support base is formed with a lower surface grinding and placement groove for vertical insertion of irregularly shaped reeds; the height of the lower surface grinding and placement groove is less than the thickness of the irregularly shaped reeds; the upper surface grinding mechanism includes an upper grinding seat located on the upper side of the conveying support base; the upper grinding seat is used to grind the upper surface of the irregularly shaped reeds.

[0021] By adopting the above technical solution, the irregularly shaped reed enters the lower surface grinding and placement groove. Since the height of the lower surface grinding and placement groove is less than the thickness of the irregularly shaped reed, the upper surface of the irregularly shaped reed is higher than the upper surface of the conveying support. Then, the conveying drive assembly drives the conveying support to move horizontally. During this process, the upper grinding seat grinds the upper surface of the irregularly shaped reed. This does not affect the conveying of the irregularly shaped reed and can simultaneously complete the grinding of the upper surface of the irregularly shaped reed, resulting in high grinding efficiency.

[0022] Optionally, the upper surface grinding mechanism further includes an upper surface grinding lifting assembly; the upper surface grinding lifting assembly is used to drive the upper grinding seat to move vertically up and down.

[0023] By adopting the above technical solution, the upper surface grinding lifting component drives the upper grinding seat to rise and fall vertically, which facilitates the maintenance of the upper grinding seat. At the same time, after the upper grinding seat is worn to a certain extent, it can be raised to avoid affecting the smooth progress of subsequent grinding.

[0024] Optionally, the middle of the conveying support is formed with a lifting drive groove that runs horizontally through it along its moving direction; the lower end of the lower surface grinding and mounting groove is opened and communicates with the lifting drive groove; a vertical discharge component is provided inside the conveying support; the vertical discharge component includes a vertically lifting top seat and a top drive component for driving the top seat to move vertically; the top seat includes a stop block that is vertically inserted into the lower surface grinding and mounting groove from bottom to top; when the stop block is at the lowest point, the distance between the upper end surface of the stop block and the upper end surface of the conveying support is less than the thickness of the irregular reed.

[0025] By adopting the above technical solution, when the irregular reed needs to be removed from the grinding and placement groove on the lower surface, the top material drive component drives the top material seat to rise, thereby causing the irregular reed on the top material seat to detach from the grinding and placement groove on the lower surface, making it convenient to remove the irregular reed.

[0026] In summary, the beneficial effects of this application are as follows:

[0027] 1. The surface treatment of irregularly shaped reeds is completed during the feeding process, without the need for manual intervention, resulting in high surface treatment efficiency.

[0028] 2. It facilitates the entry of irregularly shaped reeds into the horizontal conveyor placement slot and helps the irregularly shaped reeds reach the accurate position. Attached Figure Description

[0063] The working principle of a processing device for irregularly shaped reeds on an air-jet loom is as follows:

[0064] During operation, the stamping device 10 stamps out shaped reeds 100 from the steel strip. The shaped reeds 100 fall through the stamping forming hole 161 and the blanking hole 1110 and land in the horizontal conveying placement groove 250 directly below. Then, the radially pushing cylinder 271 drives the pushing support plate 272, a pair of pushing connecting rods 273, a pair of pushing bases 274, and a pair of pushing rods 275 to move. During this process, the pair of pushing rods 275 contact the end face where the reed teeth of the shaped reeds 100 are located. Due to the action of the pair of inclined surfaces of the horizontal conveying placement groove 250, the shaped reeds 100 finally come into contact with the horizontal conveying placement groove. When the short side of 250 is located at the end face, the position of the irregular reed 100 is fixed; then the horizontal transmission motor 22 drives the drive gear 23 to rotate, and through gear meshing, drives the horizontal transmission ring 25 to rotate 180 degrees, so that the irregular reed 100 is located directly below the vertical through hole 320. Then the vertical drive motor 46 drives the vertical drive screw 47 to rotate, so the main lifting plate 48, which is screwed to the vertical drive screw 47, descends vertically along a pair of lifting guide posts 451. Thus, the lifting pin 49 passes vertically through the vertical through hole 320 and contacts the irregular reed 100. The electromagnet at the bottom of the lifting pin 49 generates magnetism to attract the irregular reed 100. The shaped reed 100 is inserted, and then, according to the above principle, the main lifting plate 48 rises back to its original position. During this process, the shaped reed 100 passes through the vertical through hole 320, and the vertical grinding layer 321 grinds the side of the shaped reed 100. Then, the drive motor 42 rotates the rotating center column 43 and the rotating support plate 44 180 degrees so that the shaped reed 100 is directly above the lower surface grinding placement groove 640. During this process, the lower grinding layer 522 grinds the lower surface of the shaped reed 100. Then, according to the above principle, the main lifting plate 48 descends, allowing the shaped reed 100 to enter the lower surface grinding placement groove 640. Within 0, the electromagnet at the bottom of the lifting column 49 loses its magnetism, and then the main lifting plate 48 rises back to its original position. The irregular reed 100 is left in the lower surface grinding and placement groove 640. Then, the transmission drive motor 62 drives the transmission drive screw 63 to rotate, so that the transmission support seat 64 moves horizontally under the guidance of a pair of linear guide rails 611. During this process, the upper grinding layer 722 grinds the upper surface of the irregular reed 100. Finally, the top material drive component 641 drives the top material seat 642 to rise, so that the irregular reed 100 leaves the lower surface grinding and placement groove 640, which makes it easy to remove the irregular reed 100.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
