Description

Technical Field

[0001] The invention relates to the technical field of weaving equipment, in particular to an ultrasonic edge pressing device for a weaving machine. Background Art

[0002] The ultrasonic edge pressing device for a braiding machine is a device that uses ultrasonic technology to process the edge of a braided fabric. It is usually installed in the edge processing part of a braiding machine. The ultrasonic energy is used to make the fibers at the edge of the braided fabric fuse together or bond with other auxiliary materials (such as edge bands), thereby achieving the purpose of reinforcing, sealing or decorating the edge of the braided fabric.

[0003] The ultrasonic edge pressing device mainly utilizes the high-frequency vibration of ultrasound. When the device is turned on, the ultrasonic generator generates a high-frequency electrical signal, which is converted into high-frequency mechanical vibration through the transducer. This vibration is amplified by the amplitude rod and transmitted to the pressing head. When the pressing head contacts the edge of the braided fabric and the material to be pressed, the high-frequency vibration will generate friction and heat at the contact interface of the material. Under the action of local high temperature and pressure, the fiber molecules at the edge of the braided fabric rub and collide with each other, causing the molecular chains on the fiber surface to open, and then rearrange under pressure and interweave and fuse with each other.

[0004] In the process of using an ultrasonic edge pressing device to press the material after weaving by a braiding machine, some materials will be lifted up or even wrinkled on both sides during the transportation after weaving, making the appearance of the material uneven after the edge pressing treatment, affecting the edge pressing quality of the material after weaving.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example 1

[0028] See also Figure 1-Figure 7 , an ultrasonic edge pressing device for a braiding machine shown in the figure includes a carrying platform 102 arranged on the discharge port of a braiding machine body 101 for carrying and conveying a braided material 3; it also includes a U-shaped frame 2 fixed to the upper end of the carrying platform 102, the braided material 3 is between the carrying platform 102 and the U-shaped frame 2, the U-shaped frame 2 is connected with a U-shaped frame 4 through an elastic component, the U-shaped frame 4 is provided with a conveying component for conveying the braided material 3 and a driving component for driving the conveying component, connecting plates 8 are symmetrically arranged on both sides of the U-shaped frame 2, an adjusting component for adjusting the distance between the two groups of connecting plates 8 is arranged between the U-shaped frame 4 and the two groups of connecting plates 8, and an edge pressing processing component for edge pressing the braided material 3 and a pushing component for preventing the braided material 3 from wrinkling during the edge pressing process are arranged on the two groups of connecting plates 8;

[0029] It should be noted here that: in the process of ultrasonic edge pressing treatment of the woven material 3 after weaving on the braiding machine, the edge pressing treatment of the material is completed through the mutual cooperation of components such as the adjustment component, the conveying component, the edge pressing treatment component and the pushing component, and in the process of treatment, through transmission, the positions where the warping and wrinkles on the conveyed woven material 3 are squeezed and flattened, ensuring the flatness of the sides of the woven material 3 during the edge pressing treatment, and further ensuring the quality of the edge pressing treatment of the woven material 3.

[0030] Preferably, the edge pressing processing assembly includes a U-shaped mounting frame 901 fixed on the connecting plate 8, a mounting box 902 is installed on one side of the U-shaped mounting frame 901, and a pressing head 903 for abutting against the side of the woven material 3 is installed at the lower end of the mounting box 902;

[0031] It should be noted that the installation box 902 is provided with an ultrasonic generator, a transducer and a horn, wherein:

[0032] Ultrasonic generator: This is the power source of the entire edge pressing component, responsible for generating high-frequency electrical signals. It can output electrical signals of different frequencies and powers according to different woven fabric materials and edge pressing requirements;

[0033] Transducer: Its function is to convert the high-frequency electrical signal generated by the ultrasonic generator into mechanical vibration. The transducer generally uses piezoelectric ceramic materials, which will deform under the action of the electric field, thereby realizing electrical-mechanical conversion. The performance of the transducer directly affects the efficiency and stability of ultrasonic vibration. The conversion efficiency of a high-quality transducer can reach more than 90%.

[0034] Horn: used to amplify the vibration amplitude transmitted by the transducer. Because the initial vibration amplitude generated by the transducer is small and cannot meet the energy required for edge pressing, the horn can amplify the vibration amplitude several times, so that the pressure head 903 can effectively transmit the ultrasonic energy to the edge of the braid. The shape and material design of the horn will be optimized according to the specific application requirements to ensure the effective transmission and amplification of vibration;

[0035] The ultrasonic generator, transducer and amplitude transformer are conventional technical components in the ultrasonic edge pressing process and are considered as the prior art in this application, so no further elaboration is made here.

[0036] Preferably, the pushing assembly includes a rotating shaft 1001 rotatably connected to the U-shaped mounting frame 901, a first rubber wheel 1002 for pushing and extruding the woven material 3 toward both ends is rotatably connected to the rotating shaft 1001, a rotating assembly for rotating the rotating shaft 1001 is provided on the U-shaped mounting frame 901, and a transmission assembly for transmitting the rotating assembly is provided on the U-shaped frame 4; the rotating assembly includes a fixing frame 1102 fixed to the U-shaped mounting frame 901, a worm gear 1101 is fixed to the rotating shaft 1001, a connecting shaft 1103 is rotatably connected to the fixing frame 1102, a worm 1104 is fixed to the connecting shaft 1103, the worm 1104 and the worm wheel 1101 are meshed with each other, and the thread rotation directions of the worm 1104 and the worm wheel 1101 on the two sets of U-shaped mounting frames 901 are opposite;

[0037] It should be noted here that: through transmission, the two sets of connecting shafts 1103 are driven to rotate. During the rotation of the two sets of mounting shafts 1103, the two sets of worms 1104 are driven to rotate. During the rotation of the worm 1104, the two sets of rotating shafts 1001 and the first rubber wheels 1002 on the rotating shafts 1001 are driven to rotate through the mutual meshing transmission between the worm 1104 and the worm wheel 1101. Since the thread rotation directions of the worm 1104 and the worm wheel 1101 on the two sets of U-shaped mounting frames 901 are opposite, the two sets of first rubber wheels 1002 rotate in opposite directions and toward both sides of the woven material 3 after being driven.

[0038] Preferably, the conveying assembly includes a driving shaft 601 rotatably connected to the U-shaped frame 4, and two groups of second rubber wheels 602 for abutting against the upper side of the woven material 3 are fixed on the driving shaft 601; the driving assembly includes a first support frame 701 fixed to the upper end of the U-shaped frame 4, and a transmission shaft 702 is rotatably connected to the first support frame 701, and pulleys 703 are fixed on the transmission shaft 702 and the driving shaft 601, and the two groups of pulleys 703 are connected and transmitted by belts 704, and a driving motor 705 for driving the transmission shaft 702 is installed on the first support frame 701;

[0039] It should be noted here that: the transmission shaft 702 is driven to rotate by the driving motor 705. During the rotation of the transmission shaft 702, the driving shaft 601 is driven to rotate through the connection transmission between the belt 704 and the two sets of pulleys 703. During the rotation of the driving shaft 601, the second rubber wheel 602 is driven to rotate. Since the second rubber wheel 602 is against the upper surface of the woven material 3, the woven material 3 is driven to be transported on the carrier 102 through the rotation of the second rubber wheel 602 and the friction between the second rubber wheel 602 and the woven material 3.

[0040] Preferably, the transmission assembly includes a spline cylinder 1201 rotatably connected to the U-shaped frame 4, and spline shafts 1202 are slidably connected to both ends of the spline cylinder 1201, and one end of the two groups of spline shafts 1202 are respectively fixed to the two groups of connecting shafts 1103, and a linkage assembly for connecting the transmission is arranged between the spline cylinder 1201 and the drive shaft 601; the linkage assembly includes a first gear 1401 fixed to the drive shaft 601, and a second gear 1402 is fixed to the spline cylinder 1201, and the first gear 1401 and the second gear 1402 are meshed with each other;

[0041] It should be noted here that: as the drive shaft 601 rotates, the spline cylinder 1201 is driven to rotate through the mutual meshing transmission between the first gear 1401 and the second gear 1402. During the rotation of the spline cylinder 1201, the two sets of connecting shafts 1103 are driven to rotate through the connection transmission between the spline cylinder 1201 and the two sets of spline shafts 1202.

[0042] Preferably, the adjustment component includes a second support frame 1301 fixed to the upper end of the U-shaped frame 4, a double-headed threaded tube 1302 is rotatably connected to the second support frame 1301, and the threads at both ends of the double-headed threaded tube 1302 are arranged in opposite directions, and the two ends of the double-headed threaded tube 1302 are threadedly engaged with screw rods 1303, one end of the two groups of screw rods 1303 are respectively fixed to the two groups of connecting plates 8, a first sleeve 1304 is fixed to the second support frame 1301, and the two ends of the first sleeve 1304 are slidably connected to the first slide rods 1305, and one end of the two groups of first slide rods 1305 are respectively fixed to the two groups of connecting plates 8;

[0043] It should be noted here that: the double-headed threaded tube 1302 is rotated. Since the threads at both ends of the double-headed threaded tube 1302 are set in opposite directions, during the rotation of the double-headed threaded tube 1302, the two sets of screw rods 1303 are respectively engaged with the two ends of the double-headed threaded tube 1302 to drive the two sets of connecting plates 8 to move under force. During the movement of the two sets of connecting plates 8 under force, the sliding guiding effect of the first sleeve 1304 and the two sets of first sliding rods 1305 makes the two sets of connecting plates 8 after being subjected to force move closer to or away from each other, thereby adjusting the spacing between the two sets of connecting plates 8.

[0044] Preferably, the elastic component includes a plurality of groups of second sleeves 501 fixed to the upper end of the U-shaped frame 2, a second slide bar 502 is slidably connected to the second sleeve 501, one end of the second slide bar 502 is fixed to the U-shaped frame 2, a first spring 503 is sleeved on the outer side of the second sleeve 501, and both ends of the first spring 503 are respectively set against the U-shaped frame 2 and the U-shaped frame 4;

[0045] It should be noted here that: the second sleeve 501 and the second slide rod 502 are used to assist the telescopic connection of the U-shaped frame 4, and the first spring 503 is used to facilitate the squeezing and pushing of the contracted U-shaped frame 4.

[0046] In this scheme: an ultrasonic edge pressing device for a braiding machine comprises the following steps:

[0047] During the process of ultrasonic edge pressing treatment of the woven material 3 after the weaving treatment on the weaving machine, the spacing between the two groups of connecting plates 8 is adjusted according to the actual width of the woven material 3. During the adjustment process, the double-headed threaded tube 1302 is rotated. Since the threads at both ends of the double-headed threaded tube 1302 are arranged in opposite directions, during the rotation of the double-headed threaded tube 1302, the two groups of screw rods 1303 are respectively engaged with the two ends of the double-headed threaded tube 1302 to drive the two groups of connecting plates 8 to move under force. During the movement of the two groups of connecting plates 8 under force, the sliding guiding effect of the first sleeve 1304 and the two groups of first sliding rods 1305 makes the two groups of connecting plates 8 after force move closer to or away from each other, and the spacing between the two groups of connecting plates 8 is adjusted. Through the adjustment of the spacing, the edge pressing processing components on the two groups of connecting plates 8 can adapt to the width of the woven material 3 and perform ultrasonic edge pressing treatment on both sides of the woven material 3.

[0048] After the spacing adjustment of the two sets of connecting plates 8 is completed, the woven material 3 after the weaving process is passed through the U-shaped frame 2. During the passing process, the elastic force pushing action of the elastic component on the U-shaped frame 4 and the connecting action of the adjusting component on the two sets of connecting plates 8 make the second rubber wheel 602 on the U-shaped frame 4, the first rubber wheel 1002 on one side of the two sets of U-shaped mounting frames 901 and the pressure head 903 on the mounting box 902 all abut against the upper end of the woven material 3. After the woven material 3 is passed through, the drive shaft 702 is driven to rotate by the driving motor 705. During the rotation of the drive shaft 702, the connection transmission action between the belt 704 and the two sets of pulleys 703 drives the drive shaft 601 to rotate. During the rotation of the drive shaft 601, the second rubber wheel 602 is driven to rotate. 602 abuts against the upper surface of the woven material 3, and through the rotation of the second rubber wheel 602 and the friction between the second rubber wheel 602 and the woven material 3, the woven material 3 is driven to be transported on the carrier 102 under force. During the transportation of the woven material 3, because the pressure head 903 keeps against the upper side of the woven material 3, a high-frequency electrical signal is generated by the ultrasonic generator installed inside the box 902, and then the electrical signal is converted into high-frequency mechanical vibration through the transducer. This vibration is amplified by the amplitude rod and then transmitted to the pressure head 903. The high-frequency vibration will generate friction and heat at the contact interface of the material. Under the action of local high temperature and pressure, the fiber molecules at the edge of the woven fabric rub and collide with each other, so that the molecular chains on the fiber surface are opened, and then rearranged under pressure and intertwined and fused to achieve ultrasonic pressing operation;

[0049] In the process of ultrasonic pressing, as the driving shaft 601 rotates, the spline cylinder 1201 is driven to rotate through the mutual meshing transmission between the first gear 1401 and the second gear 1402. During the rotation of the spline cylinder 1201, the two sets of connecting shafts 1103 are driven to rotate through the connection transmission between the spline cylinder 1201 and the two sets of spline shafts 1202. During the rotation of the two sets of installation shafts 1103, the two sets of worms 1104 are driven to rotate. During the rotation of the worm 1104, the two sets of rotating shafts 1001 and the first rubber wheel 1101 on the rotating shaft 1001 are driven through the mutual meshing transmission between the worm 1104 and the worm wheel 1101. 002 rotates, and because the thread rotation directions of the worm 1104 and the worm wheel 1101 on the two sets of U-shaped mounting frames 901 are opposite, the two sets of first rubber wheels 1002 rotate in opposite directions and toward the two sides of the woven material 3 after being driven. In the process of rotation, because the first rubber wheels 1002 are against the upper side of the woven material 3, the rotation of the two sets of first rubber wheels 1002 generates a force pushing the conveyed woven material 3 toward both ends, and the positions where warping and wrinkles occur on the conveyed woven material 3 are squeezed and flattened, thereby ensuring the flatness of the sides of the woven material 3 during the edge pressing process, and further ensuring the edge pressing process quality of the woven material 3.
