Description

Technical Field

[0001] This invention relates to the field of garment processing machinery technology, specifically to a circle and bow forming machine. Background Technology

[0002] In the apparel industry, raw materials such as webbing, ribbons, elastic bands, leather belts, synthetic fiber belts, and fabric strips are frequently used to make circles and bows. These serve as the base for headdresses, brooches, clothing decorations, and gift decorations, or as the base for elastic bands and other garment components in casual trousers. Currently, these circles and bows used in the apparel industry are typically sewn manually using sewing machines, resulting in low production efficiency, high labor costs, and unsightly stitches. While machines using steel wire, lead wire, and steel strips to make circles are more common in industrial manufacturing (e.g., a fully automatic circle-making machine disclosed in Chinese patent application CN115338333A and a circle-making machine disclosed in Chinese patent application CN107695236A), these machines, designed for making circles from rigid materials, are not effectively applicable to making circles from soft materials in the apparel industry. Furthermore, none of the existing processing machines can produce both circles and bows without altering the hardware components. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the prior art by providing a compact structure, a small installation footprint, high production efficiency, and a circle and bow forming machine that can use raw materials to make both circles and bows.

[0004] The technical solution of the present invention is as follows: The circle and bow forming machine of the present invention includes a cabinet as the mounting base, a feeding mechanism located on one side of the cabinet for storing and conveying raw materials to be processed, and its structural features are as follows: it also includes a pulling mechanism located on the other side of the cabinet for repeatedly pulling the raw materials to be processed from the feeding mechanism, a pressing mechanism for pressing the raw materials to be processed pulled out by the pulling mechanism to a set length, a cutting mechanism for cutting the raw materials to be processed after being pressed to the set length to form a material segment to be processed, two sets of clamping and flipping mechanisms for clamping the two ends of the material segment to be processed and flipping them together in the middle, an ultrasonic welding mechanism for welding at the joint of the two ends of the material segment to be processed, an intermediate drive mechanism located in the cabinet as the mounting base for the pressing mechanism and the two sets of clamping and flipping mechanisms and driving the pressing mechanism and the two sets of clamping and flipping mechanisms to move back and forth as a whole, and an electrical control component for operation control.

[0005] A further embodiment is as follows: The ultrasonic welding mechanism includes a first mounting bracket fixedly mounted above the center of the cabinet, a welding drive cylinder mounted above the first mounting bracket, a second mounting bracket movably mounted within the first mounting bracket and connected to the welding drive cylinder, and a welding ultrasonic component and a welding mold assembly; the welding ultrasonic component includes an ultrasonic welding head and a second ultrasonic transducer fixedly mounted on the second mounting bracket, and a second ultrasonic generator mounted within the cabinet; the welding mold assembly includes a welding mold, a connecting plate, a transmission rod, and a welding mold drive cylinder fixedly mounted on the cabinet, with the welding mold fixed to the connecting plate at its rear end. The transmission rod is fixedly connected to the connecting plate at its front end and to the welding mold drive cylinder at its rear end. During operation, the actions of the welding drive cylinder, the welding mold drive cylinder, and the second ultrasonic generator are all controlled by the aforementioned electrical control components. Under the drive of the welding mold drive cylinder, the front end of the welding mold can extend forward toward the front of the cabinet and be located below the ultrasonic welding head. When making a circle, the forward extension of the welding mold occurs later than the forward movement of the aforementioned pressing mechanism and the two sets of clamping and flipping mechanisms. When making a bow, the forward extension of the welding mold occurs synchronously with the forward movement of the aforementioned pressing mechanism and the two sets of clamping and flipping mechanisms.

[0007] A further solution is as follows: the intermediate drive mechanism includes an intermediate plate located inside the cabinet, a support guide rod for supporting the movement of the intermediate plate, and an intermediate plate drive cylinder for driving the intermediate plate to move back and forth along the support guide rod; the material pressing mechanism and the two sets of clamping and flipping mechanisms are all fixedly mounted on the intermediate plate; during operation, the movement of the intermediate plate drive cylinder is controlled by the electronic control components.

[0008] A further embodiment is as follows: the aforementioned pressing mechanism includes a pressing rod drive motor fixedly mounted on the intermediate plate of the aforementioned intermediate drive mechanism, a slider guide rail transmission assembly connected to the aforementioned pressing rod drive motor, and two pressing rods mounted on the aforementioned slider guide rail transmission assembly; during operation, the two pressing rods can extend forward of the aforementioned cabinet under the drive of the intermediate drive mechanism, and the two pressing rods can move up and down under the drive of the pressing rod drive motor and the transmission of the slider guide rail transmission assembly; the operation of the aforementioned pressing rod drive motor is controlled by the aforementioned electronic control assembly.

[0009] A further solution is as follows: The aforementioned clamping and flipping mechanism includes two clamping components and a clamping component driving cylinder. The two clamping components are arranged vertically opposite each other and are both connected to the clamping component driving cylinder. The clamping component driving cylinders of the two sets of clamping and flipping mechanisms are fixedly installed on the intermediate plate of the aforementioned intermediate drive mechanism. During operation, under the drive of the intermediate drive mechanism, the two clamping components of each of the two sets of clamping and flipping mechanisms can extend forward to the front of the aforementioned cabinet and be located on both sides of the aforementioned ultrasonic welding mechanism. The clamping component driving cylinders of the two sets of clamping and flipping mechanisms respectively drive the corresponding two clamping components to clamp the material segment to be processed and then perform a flipping action. The actions of the two clamping component driving cylinders are controlled by the aforementioned electrical control components.

[0010] A further option is that the aforementioned clamping component is a bent square rod composed of a clamping section, a connecting section, and an installation section connected integrally or fixedly in sequence; or, the aforementioned clamping component is a round rod.

[0011] A further embodiment is as follows: the cutting mechanism includes a cutter mounting bracket fixed on the cabinet, a cutter drive cylinder mounted on the cutter mounting bracket, a cutter connected to the cutter drive cylinder, and a cutting ultrasonic component that cooperates with the cutter; the cutting ultrasonic component includes an ultrasonic cutter welding head fixed on the cabinet, a first ultrasonic transducer, and a first ultrasonic generator located inside the cabinet; the upper end of the ultrasonic cutter welding head is located below the cutter, and the actions of the cutter drive cylinder and the first ultrasonic generator are controlled by the aforementioned electrical control component during operation.

[0012] A further solution is: the cutting mechanism includes scissors and a scissor drive cylinder. The scissor drive cylinder is connected to the scissors drive and is fixedly mounted on the intermediate plate of the intermediate drive mechanism. During operation, the movement of the scissor drive cylinder is controlled by the electronic control components.

[0013] Further options include: the aforementioned electrical control components include a touch screen for human-machine interaction mounted on the aforementioned cabinet, a solenoid valve group consisting of several solenoid valves mounted inside the cabinet, and a programmable logic controller (PLC) for main control mounted inside the cabinet; each solenoid valve of the aforementioned touch screen and solenoid valve group is electrically connected to the PLC.

[0014] The present invention has the following positive effects: (1) The circle and bow forming machine of the present invention, through the new design of the overall structure, enables a single machine to be used to produce both circles and bows without any changes to the components, filling the gap in such processing machinery in the industry. (2) The present invention can produce both circles and bows automatically during use, with high production efficiency and significantly reduced labor costs, thus effectively solving the problem of low production efficiency and high labor costs caused by manual sewing of such circles and bows in the garment industry in the prior art. (3) The joints of the circles and bows produced by the present invention are ultrasonically welded and can be patterned or decorated at the joints, making the joints neat and beautiful, thus effectively solving the problem of poor product aesthetics caused by sewing at the joints when using a sewing machine in the prior art.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0040] (Example 1)

[0041] See Figures 1 to 9 The circle and bow forming machine of this embodiment mainly consists of a cabinet 1, a feeding mechanism 2, a pulling mechanism 3, a pressing mechanism 4, a clamping and flipping mechanism 5, an intermediate driving mechanism 6, a cutting mechanism 7, an ultrasonic welding mechanism 8, and an electrical control component 9.

[0042] The cabinet 1 serves as the mounting base for all functional components of the machine. In a specific implementation, the cabinet 1 mainly consists of a frame 11 as the skeleton, a front lower plate 12 and a rear lower plate (not marked in the figure) fixedly installed on the lower front and rear sides of the frame 11, side lower plates 13 fixedly installed on the lower left and right sides of the frame 11, a front upper plate 14 and a rear upper plate 15 fixedly installed on the upper front and rear sides of the frame 11, a left upper bent plate 16 and a right upper bent plate 17 fixedly installed on the upper left and right sides and on top of the frame 11, support feet 18 fixedly installed at the four corners below the frame 11, and connecting rods 19 fixedly installed between the front upper plate 14 and the rear upper plate 15 and fixing the front upper plate 14 and the rear upper plate 15 together. The upper front plate 14 has two vertically oriented pressure rod movable grooves 14-1 in the middle. The upper front plate 14, upper rear plate 15, upper left bending plate 16, and upper right bending plate 17 also have other functional mounting grooves or holes, which are not all marked in the figure.

[0043] The feeding mechanism 2 is used for storing and conveying the raw materials to be processed. The feeding mechanism 2 is located on the upper right side of the cabinet 1. In this embodiment, the feeding mechanism 2 mainly consists of a feeding tray 21, a feeding tray mounting rod 22, a guide frame 23, a feeding roller 24, a feeding roller mounting frame 25, and a feeding roller drive motor 26; the feeding roller 24 is a pair of rollers, including a steel driving roller 24-1 and a rubber driven roller 24-2. The feeding tray 21 is rotatably mounted on the feeding tray mounting rod 22, which is fixedly mounted on the cabinet 1. The guide frame 23 and the feeding roller mounting frame 25 are fixedly mounted on the front end face of the front upper plate 14 of the cabinet 1. The driving roller 24-1 and driven roller 24-2 of the feeding roller 24 are rotatably mounted inside the feeding roller mounting frame 25. The feeding roller drive motor 26 is fixedly mounted inside the cabinet 1 and is connected to the driving roller 24-1 for transmission, driving the driving roller 24-1 to rotate. In use, the feeding tray 21 is used to place the raw material roll, the guide frame 23 is used to limit and guide the movement of the raw material released from the feeding tray 21, and the feeding roller 24 is used to traction the raw material passing through the guide frame 23.

[0044] The material pulling mechanism 3 is used to repeatedly pull the raw material to be processed from the feeding mechanism 2 for the cutting mechanism 7 to cut into the material segments to be processed. The material pulling mechanism 3 is located on the upper left side of the cabinet 1. The material pulling mechanism 3 mainly consists of a material pulling cylinder 31, a transmission connector 32, a clamping cylinder 33, and a gripper 34. The gripper 34 consists of two openable and closable claws. The clamping cylinder 33 is connected to the gripper 34 through a transmission connection, driving the gripper 34 to clamp and release the end of the raw material. The material pulling cylinder 31 is fixed on the upper left bending plate 16 of the cabinet 1 and drives the clamping cylinder 33 and the gripper 34 to move left and right together through the transmission connector 32.

[0045] The pressing mechanism 4 is used to press down the raw material to be processed, pulled out by the pulling mechanism 3 from the feeding mechanism 2, to a set length in order to create circles or bows. See also Figure 1 and Figure 6 The pressing mechanism 4 mainly consists of pressing rods 41, a slider guide rail transmission assembly 42, and a pressing rod drive motor 43. Two pressing rods 41 are mounted on the slider guide rail transmission assembly 42. The pressing rod drive motor 43, through the transmission of the slider guide rail transmission assembly 42, enables the two pressing rods 41 to move vertically within the two pressing rod movable slots 14-1 on the front upper plate 14 of the cabinet 1. The combination of the pressing rod drive motor 43 and the slider guide rail transmission assembly 42 is a mature existing technology, and its specific structure will not be described in detail.

[0046] The clamping and flipping mechanism 5 is used to clamp both ends of the material segment to be processed and flip it towards the ultrasonic welding mechanism 8 for ultrasonic welding. Two sets of the clamping and flipping mechanism 5 with identical structures are provided, one set on each side of the ultrasonic welding mechanism 8 on the cabinet 1. The clamping and flipping mechanism 5 mainly consists of two clamping components 51 and a clamping component drive cylinder 52. The two clamping components 51 are arranged vertically and are both connected to the clamping component drive cylinder 52. In use, the clamping component drive cylinder 52 drives the two clamping components 51 to first clamp the material segment to be processed and then flip it. The clamping component drive cylinder 52 is a commercially available component, and its structure and working principle are mature existing technologies, which will not be described in detail. As a specific implementation, the clamping component 51 adopts the following... Figure 1 The circular rod 51-1 shown; as another preferred implementation, the clamping member 51 adopts the following... Figure 7 and Figure 8 The bent square rod 51-2 shown is composed of a clamping section 51-2-1, a connecting section 51-2-2, and an mounting section 51-2-3, which are integrally or fixedly connected in sequence. More preferably, the front end of the clamping section 51-2-1 of the bent square rod 51-2 has a chamfered end 51-2-1-1 to allow the clamping member 51 to extend outwards and avoid the material to be processed during use. The preferred use of the bent square rod 51-2 over the round rod 51-1 allows for a tighter clamping of the material to be processed during use. Furthermore, when the material is flipped and welded on the ultrasonic welding mechanism 8, the overlap between the two ends of the material to be processed is shorter, and the connection between the two ends is neater, improving product processing quality. Obviously, the clamping member 51 is not limited to the two structures mentioned above. Other similar structures, such as rectangular clamping plates, that can achieve the function of the clamping member 51 are not listed in this embodiment, but are clearly within the scope of protection of this invention.

[0047] The intermediate drive mechanism 6 serves as the mounting base for the pressing mechanism 4 and the clamping and flipping mechanism 5 and is used to drive the pressing mechanism 4 and the clamping and flipping mechanism 5 to move forward and backward as a whole, so that the two pressing rods 41 of the pressing mechanism 4 and the two flipping parts 51 of each of the two sets of clamping and flipping mechanisms 5 can extend forward and retract backward through the corresponding functional holes (not marked in the figure) provided on the front upper plate 14 of the cabinet 1. The intermediate drive mechanism 6 includes an intermediate plate 61, supporting guide rods 62, guide sleeves 63, and an intermediate plate drive cylinder 64. One guide sleeve 63 is fixedly installed at each of the four corners of the intermediate plate 61. The guide sleeves 63 are preferably arranged in this configuration. Each supporting guide rod 62 is fixedly connected to the front upper plate 14 and rear upper plate 15 of the cabinet 1 at both its front and rear ends and is fixedly installed inside the cabinet 1. Each of the four guide sleeves 63 is movably sleeved with one supporting guide rod 62, allowing the intermediate plate 61 to move back and forth based on the four supporting guide rods 62. The intermediate plate drive cylinder 64 is fixedly installed on the cabinet 1 and is connected to the intermediate plate 61 for transmission, driving the intermediate plate 61 to move back and forth. The aforementioned slider guide rail transmission assembly 42 and pressing rod drive motor 43 of the pressing mechanism 4, as well as the clamping component drive cylinders 52 of the two sets of clamping and flipping mechanisms 5, are all fixedly installed on the intermediate plate 61.

[0048] The cutting mechanism 7 is used to cut the raw material to be processed into segments. In this embodiment, the cutting mechanism 7 mainly consists of a cutter 71, a cutter drive cylinder 72, a cutter mounting bracket 73, and a cutting ultrasonic component 74. The cutter 71 and the cutter drive cylinder 72 are connected by transmission and are both fixed on the cutter mounting bracket 73, which is fixedly located at the upper middle part of the cabinet 1. The cutting ultrasonic component 74 is a commercially available part, which includes an ultrasonic cutting head 74-1 fixed on the front upper plate 14 of the cabinet 1, a first ultrasonic transducer 74-2, and a first ultrasonic generator 74-3 located inside the cabinet 1. The upper end of the ultrasonic cutting head 74-1 is located below the cutter 71. During operation, the cutter 71 moves up and down under the drive of the cutter drive cylinder 72. The cutter 71 and the ultrasonic cutting head 74-1 cooperate to cut the raw material to be processed into segments.

[0049] The ultrasonic welding mechanism 8 is used to weld the cut material segments into circles or bows. The ultrasonic welding mechanism 8 includes an outer casing 81, a first mounting frame 82, a welding drive cylinder 83, a second mounting frame 84, a welding ultrasonic component 85, a welding mold assembly 86, and a fan 87. The first mounting frame 82 is fixedly installed above the center of the cabinet 1 and located to the left of the cutting mechanism 7. The welding drive cylinder 83 is fixedly installed above the first mounting frame 82. The second mounting frame 84 is movably installed inside the first mounting frame 82 and is connected to the welding drive cylinder 83. The welding ultrasonic component 85 is a commercially available part. The welding ultrasonic component 85 includes an ultrasonic welding head 85-1 and a second ultrasonic transducer 85-2 fixedly installed on the second mounting frame 84, and a second ultrasonic generator 85-3 installed inside the cabinet 1. The ultrasonic welding head 85-1 extends downward from the first mounting frame 82 and can move up and down with the second mounting frame 84. The welding mold assembly 86 includes a welding mold 86-1, a connecting plate 86-2, a transmission rod 86-3, and a welding mold drive cylinder 86-4. The welding mold 86-1 is a rectangular strip structure. The rear end of the welding mold 86-1 is fixedly connected to the connecting plate 86-2. The front end of the welding mold 86-1 can extend forward from the corresponding functional hole provided on the front upper plate 14 of the cabinet 1 and is located below the ultrasonic welding head 85-1 of the ultrasonic welding assembly 85. The front end of the transmission rod 86-3 is fixedly connected to the connecting plate 86-2. The rear end of the transmission rod 86-3 can movably pass through the intermediate plate 61 and is connected to the welding mold drive cylinder 86-4 fixedly provided on the rear plate 15 of the cabinet 1. As a preferred embodiment, the upper surface of the welding mold 86-1 can be provided with corresponding patterns or designs as needed, so that the circles or bows produced form corresponding patterns or designs at the welding point, increasing the aesthetics of the product. The outer casing 81 and the fan 87 are both preferably configured. The outer casing 81 is fixedly mounted on the outer periphery of the first mounting bracket 82 and the welding drive cylinder 83. The fan 87 is fixedly mounted on the first mounting bracket 82 and extends outward from the outer casing 81. When in use, the fan 87 is used to cool the welding ultrasonic component 85.

[0050] See Figure 9The electrical control component 9 is used for the operation control of the circle and bow forming machine in this embodiment. The electrical control component 9 includes a touch screen 91 for human-machine interaction mounted on the cabinet 1, a solenoid valve group consisting of several solenoid valves 92 mounted inside the cabinet 1, and a programmable logic controller (PLC) for main control mounted inside the cabinet 1. Each cylinder is equipped with at least one solenoid valve 92, and each solenoid valve 92 is used to control the air passage of the corresponding cylinder, thereby controlling the operation of the cylinder accordingly. The touch screen 91 and each solenoid valve 92 of the solenoid valve group are electrically connected to the programmable logic controller. The operation of the feeding roller drive motor 26 of the feeding mechanism 2, the pressing rod drive motor 43 of the pressing mechanism 4, the first ultrasonic generator 74-3 of the cutting ultrasonic component 74, and the second ultrasonic generator 85-3 of the welding ultrasonic component 85 are all controlled by the programmable logic controller. The operation of each cylinder is controlled by the programmable logic controller through the corresponding solenoid valve 92.

[0051] The working principle and process of the circle and bow forming machine in this embodiment are briefly described below, depending on whether it is used to make circles or bows:

[0052] Processing and manufacturing circle 100: See Figure 1 and Figure 10 In this embodiment, when the circle and bow forming machine is used to process and make circle 100, in the initial state, the end of the raw material to be processed is conveyed to the right side of the cutting mechanism 7 by the feeding mechanism 2. The cutter 71 and the ultrasonic cutter welding head 74-1 of the ultrasonic cutting component 74 are separated. The gripper 34 of the pulling mechanism 3 is in the initial position on the left. The two clamping parts 51 of each of the two sets of clamping and flipping mechanisms 5 and the two pressing rods 41 of the pressing mechanism 4 are all in the state of being retracted into the cabinet 1 and the two pressing rods 41 are in the initial upper position.

[0053] After starting the operation, under the control of the electronic control component 9, the pulling cylinder 31 of the pulling mechanism 3 drives the clamping cylinder 33 and the gripper 34 to move to the right through the transmission connector 32 until the two open jaws of the gripper 34 hold the end of the material to be processed. Then, the clamping cylinder 33 drives the two open jaws of the gripper 34 to close and clamp the end of the material to be processed. Next, the pulling cylinder 31 drives the clamping cylinder 33 and the gripper 34 to move to the left to reset. At the same time, the gripper 34 pulls the material to be processed from the feeding mechanism 2 by a set length to become the material segment to be processed. Then, the intermediate plate drive cylinder 64 of the intermediate drive mechanism 6 drives the intermediate plate 6. 1. The forward movement drives the clamping parts 51 of the two sets of clamping and flipping mechanisms 5 and the two pressing rods 41 of the pressing mechanism 4 to extend simultaneously from the front upper plate 14 of the cabinet 1 to the front of the cabinet 1. The material to be processed passes between the two pairs of clamping parts 51 and under the two pressing rods 41. Then, the pressing rod drive motor 43 of the pressing mechanism 4 drives the two pressing rods 41 to move downward to a set distance in the two pressing rod movable slots 14-1 of the front upper plate 14 of the cabinet 1 through the transmission of the slider guide rail transmission assembly 42. Since the left end of the material to be processed is clamped by the claw 34 of the pulling mechanism 3, the downward movement of the two pressing rods 41 presses the material to be processed towards the front upper plate 14. The material is fed downwards by the feeding mechanism 2, causing the length of the material to be processed to continuously increase. When the two pressure rods 41 move downwards to their positions, the length of the material to be processed reaches the set length. At this time, the welding mold 86-1 of the welding mold assembly 86 of the ultrasonic welding mechanism 8 extends from the front upper plate 14 of the cabinet 1 to the front of the front upper plate 14 under the drive of the welding mold drive cylinder 86-4. The cutter 71 of the cutting mechanism 7 moves downwards under the drive of the cutter drive cylinder 72 and cooperates with the ultrasonic cutter welding head 74-1 of the cutting ultrasonic assembly 74 to cut off the right side of the material to be processed. At the same time, the gripper 34 of the pulling mechanism 3 releases the left end of the material to be processed. Immediately afterwards, the two pairs of clamping parts 51 of each of the two pairs of clamping and flipping mechanisms 5 clamp the material segment to be processed under the drive of the corresponding clamping part drive cylinder 52, and then flip it from the left and right sides to the middle, so that the left and right ends of the material segment to be processed overlap each other above the welding mold 86-1 of the welding mold assembly 86 of the ultrasonic welding mechanism 8; then the ultrasonic welding head 85-1 of the ultrasonic welding ultrasonic component 85 of the ultrasonic welding mechanism 8 moves downward to above the overlap of the two ends of the material segment to be processed under the drive of the welding drive cylinder 83, and cooperates with the welding mold 86-1 to perform ultrasonic welding, thereby welding the two ends of the material segment to be processed together.After welding is completed, the pressing rod 41 of the pressing mechanism 4, the clamping parts 51 of the two sets of clamping and flipping mechanisms 5, the cutter 71 of the cutting mechanism 7, the ultrasonic welding head 85-1 of the ultrasonic welding component 85 of the ultrasonic welding mechanism 8, and the welding mold 86-1 of the welding mold component 86 are simultaneously reset. The processed circle 100 automatically falls into the equipped receiving device (not shown in the figure), and then the aforementioned actions are repeated to automatically process the next circle 100.

[0054] Processing and making bow 101: In this embodiment, the circle and bow forming machine performs the same actions as the circle 100 when processing and making bow 101. The difference is that when processing and making bow 101, the welding mold 86-1 of the welding mold assembly 86 of the ultrasonic welding mechanism 8, the clamping parts 51 of the two sets of clamping and flipping mechanisms 5, and the two pressing rods 41 of the pressing mechanism 4 simultaneously extend from the front upper plate 14 of the cabinet 1 to the front of the upper plate 14. This is different from the time when the welding mold 86-1 extends after the clamping parts 51 and the pressing mechanism 4 extend from the front upper plate 14 of the cabinet 1 when processing and making circle 100. In addition to passing between the two pairs of clamping parts 51 and under the two pressing rods 41 as in the process of making circle 100, the material to be processed also passes through the welding mold 86-1 at the same time as the circle 100. Above 6-1; when the two pressing rods 41 of the pressing mechanism 4 press down the material to be processed, the material to be processed moves down simultaneously on the left and right sides of the welding mold 86-1 to form two V-shapes. The right end of the material to be processed cut by the cutting mechanism 7 and the left end of the material to be processed released by the pulling mechanism 3 are clamped and flipped by the two pairs of clamping and flipping mechanisms 5 and overlap each other above the material to be processed that is close to the upper surface of the welding mold 86-1. Then the ultrasonic welding mechanism 8 welds the two ends of the material to be processed and the material to be processed below the overlap together. After the welding is completed, the relevant mechanisms are reset as described above, and the processed bow 101 automatically falls into the equipped receiving device (not shown in the figure). Then the above actions are repeated to automatically process the next bow 101.

[0055] It should be noted that the circle and bow forming machine of this embodiment is not only applicable to the clothing industry, but also applicable to materials with appropriate hardness such as steel wire, lead wire and steel plate strip.

[0056] As can be seen from the foregoing, the circle and bow forming machine of this embodiment can be used to produce both circles and bows, filling the gap in such processing machinery in the industry. The production of both circles and bows can be fully automated, with high production efficiency and significantly reduced labor costs. Moreover, ultrasonic welding makes the weld joints neat and beautiful, thus effectively solving the problems of low production efficiency, high labor costs, and poor sewing thread appearance caused by the fact that the processing of such circles and bows in the garment industry is usually done manually using sewing machines in the prior art.

[0057] (Example 2)

[0058] See Figure 12 and Figure 13 In this embodiment, the circle and bow forming machine is the same as in embodiment 1 in other aspects, except that: in this embodiment, the feeding mechanism 2 consists only of a feeding tray 21, a feeding tray mounting rod 22, and a guide frame 23. During use, the pulling mechanism 3 directly pulls the raw material to be processed from the left end of the guide frame 23; the cutting mechanism 7 consists of scissors 75 and scissor drive cylinder 76. The scissor drive cylinder 76 is connected to the scissors 75 and enables the scissors 75 to perform automatic cutting action. The scissor drive cylinder 76 is controlled by a programmable logic controller via a correspondingly set solenoid valve 92. It should be noted that the scissor drive cylinder 76 is a commercially available part, and the transmission connection and installation method between the scissor drive cylinder 76 and the scissors 75 are mature existing technologies, which will not be described in detail. The scissor drive cylinder 76 is fixedly mounted on the intermediate plate 61 of the intermediate drive mechanism 6. During use, it moves synchronously with the pressing rod 41 of the pressing mechanism 4 and the clamping part 51 of the clamping and flipping mechanism 5 to extend out of the front upper plate 14 of the cabinet 1 or to reset.

[0059] The above embodiments are descriptions of specific implementations of the present invention, and not limitations thereof. Those skilled in the art can make various modifications and changes without departing from the spirit and scope of the present invention to obtain corresponding equivalent technical solutions. Therefore, all equivalent technical solutions should be included in the patent protection scope of the present invention.
