In this embodiment, the dividing strip assembly 3 is controlled to lift by multiple lifting cylinders 32 during processing. The drive motor drives the rotating shaft to rotate, and the rotating shaft drives the circular blades fixed on its shaft to rotate, cutting the incoming fabric into the required small strips of fabric with openings.

[0044] In some embodiments, see Figure 4-5 As shown, the weld isolation assembly 4 includes a weld isolation bracket 41, a transmission structure 42, a weld isolation tooth mold 43, a first weld isolation structure 44, and a second weld isolation structure 45. The weld isolation bracket 41 is mounted on the frame 1, the transmission structure 42 is rotatably mounted on the weld isolation bracket 41, and the weld isolation tooth mold 43 is mounted on the transmission structure 42. The first weld isolation structure 44 and the second weld isolation structure 45 are symmetrically distributed at the upper and lower ends of the weld isolation tooth mold 43, and the first weld isolation structure 44 and the second weld isolation structure 45 are respectively connected to the weld isolation bracket 41 through a lifting structure.

After the welding is completed, the opening and depth of the medium-efficiency air filter bag are basically determined.

[0046] In some embodiments, see Figure 6-7 As shown, the welding and cutting assembly 5 includes a welding and cutting bracket 51, a forward and reverse threaded screw structure 52, a first welding and cutting structure 53, and a second welding and cutting structure 54. The forward and reverse threaded screw structure 52 is mounted on the welding and cutting bracket 51. The first welding and cutting structure 53 and the second welding and cutting structure 54 are symmetrically mounted on the forward and reverse threaded screw structure 52. The first welding and cutting assembly 5 and the second welding and cutting structure 54 are respectively provided with a movable seat 55, a lifting welding part 56, a rotation drive part 57, a welding wheel 58, and a cutting wheel 59. The movable seat 55 is mounted on the forward and reverse threaded screw structure 52. The lifting welding part 56 is rotatably mounted on the welding and cutting bracket 51.

The welding wheel 58 and the cutting wheel 59 are located above the lifting welding part 56.

[0047] In this embodiment, the first welding structure 53 and the second welding structure 54 are symmetrically installed and reciprocate through the positive and negative threaded screw structure 52. The lifting welding part is specifically equipped with a lifting cylinder, a rotation drive structure and an ultrasonic welding head. The welding head is installed at the bottom of the lifting cylinder and connected to the rotation drive structure to realize rotation welding. More specifically, the rotation drive structure here can be connected to the main transmission structure 11 through the cooperation of a synchronous wheel, a hexagonal steel and a sprocket structure to realize transmission.

[0048] During the welding process, the lifting cylinder drives the ultrasonic welding head to descend. Specifically, there are two ultrasonic welding heads. The two ultrasonic welding heads press against the welding wheel and the cutting wheel respectively. Through the ultrasonic welding action, the fabric is welded and cut. Because a rotating toothed mold and a rotating ultrasonic welding head are used, the welding effect is better and stronger, without wrinkles, and the cut edges are more beautiful and burr-free.

[0049] Based on the above embodiments, as shown in 8 and 10, this embodiment further includes an auxiliary welding assembly 8. The auxiliary welding assembly 8 is provided with a fixed frame 81, a first rotating shaft 82, a welding wheel structure 83, an ultrasonic welding structure 84, a second rotating shaft 85, and an oxy-fuel cutting tool structure 86. The fixed frame 81 is installed on the frame 1. The first rotating shaft 82 and the second rotating shaft 85 are rotatably installed on the fixed frame 81, respectively. The welding wheel structure 83 is installed on the first rotating shaft 82. The ultrasonic welding structure is installed on the fixed frame 81 and located below the welding wheel structure 83 for cooperating with the welding wheel structure 83 to perform welding. The oxy-fuel cutting tool structure 86 is installed on the second rotating shaft 85 and is provided corresponding to the welding wheel structure 83 for cutting the excess fabric formed after welding by the welding wheel structure 83.

[0050] Specifically, in this embodiment, a material pulling wheel is also required. The shaft end of the material pulling wheel is connected to the main drive structure 11 for pulling the material for melting and cutting. In this embodiment, there are three sets of melting wheel structure 83, ultrasonic welding structure 84 and gas cutting blade structure 86. This process is also melting and cutting at the same time. It is mainly used when the melting and cutting component 5 cannot work at certain dimensions, or when the fabric is divided in half. During melting and cutting, the material pulling wheel pulls the fabric over, and the fabric sandwiched between the ultrasonic welding structure 84 and the melting wheel structure 83 is welded under the action of the ultrasonic welding structure 84. Then, the excess fabric is cut off under the action of the gas cutting blade structure 86.

[0051] Based on the above embodiments, in this embodiment, see... Figure 13 As shown, a waste collection component 9 is also provided. The waste collection component 9 is installed on the frame 1 and is located near the melting and cutting component 5 and the auxiliary melting component 8. The waste collection component 9 is provided with a receiving box 91, a receiving wheel 92, and a conveying rubber roller structure 93. The receiving box 91 and the receiving wheel 92 are respectively located on the frame 1. The conveying rubber roller structure 93 is rotatably located in the receiving box 91 and is used to rotate and roll up the fabric to roll up the excess fabric cut by the melting and cutting component 5 and the auxiliary melting component 8.

[0052] In this embodiment, the conveying roller structure 93 is also connected to the main drive to collect waste materials and avoid interfering with the finished product end.

[0053] In some embodiments, see Figure 8-9As shown, the end-melting assembly 6 includes an end-melting bracket 61, a roller material storage structure 62, a movable bracket 64, an end-melting cylinder 63, an end-melting welding structure 65, a strip welding die 66, and a material removal structure 67. The end-melting bracket 61 is mounted on the frame 1. The roller material storage structure 62 is mounted on the end-melting bracket 61 for storing material. The end-melting cylinder 63 is mounted on the end-melting bracket 61. The movable bracket 64 is located at the output end of the end-melting cylinder 63. The end-melting welding structure 65 is mounted on the movable bracket 64. The strip welding die 66 is mounted on the end-melting bracket 61, located below the end-melting welding structure 65, and corresponding to the end-melting welding structure 65. The material removal structure 67 is mounted on the end-melting bracket 61 and close to the strip welding die 66 for pushing and removing the fabric adhered to the strip welding die 66.

[0054] In this embodiment, the main application is end welding. First, the fabric is clamped by the end welding cylinder 63. Under the action of the end welding structure 65, the fabric clamped between the strip welding die 66 and the end welding structure 65 is welded. After welding, the material removal structure 67, which can be composed of a cylinder and a material removal plate, is used. The cylinder pushes the material removal plate to remove the fabric that may be stuck to the strip welding die 66. Through this process, the basic shape of the medium-efficiency air filter bag is formed.

[0055] In this embodiment, the roller material storage structure 62 consists of a material pulling wheel, a material pulling shaft, and a material pulling roller. The material pulling wheel can be connected to the main drive to pull the material. The material pulling roller includes a first roller roller and a second roller roller that are movably mounted on the material pulling shaft. This process is for the end-welding assembly 6 to store material. After the material is stored, the end-welding assembly 6 can more accurately find the required welding position when performing ultrasonic welding, thereby improving the welding accuracy.

[0056] In some embodiments, see Figure 11-12 As shown, the slitting assembly 7 includes a lead screw structure 71, a slitting platform 72, a pressing structure 73, a belt conveyor structure 74, and a blade structure 75. The lead screw structure 71 is mounted on the frame 1, and the slitting platform 72 is mounted on the frame 1 via the lead screw structure 71. The pressing structure 73 and the belt conveyor structure 74 are respectively mounted on the slitting platform 72. The belt conveyor structure 74 is provided with a belt seat, and the blade structure 75 is mounted on the belt seat.

[0057] In this embodiment, specifically, the lead screw structure 71 is connected to a bevel gear on the transmission shaft at the output end of the drive motor via a bevel gear at the shaft end, thereby driving the slitting platform 72 to move back and forth. To achieve stable movement, a slide rail can be installed on the frame 1, connecting the slitting platform 72 to the slide rail for more stable movement. Additionally, a material pulling wheel structure is required for material pulling. The pressing structure 73 in this embodiment can specifically consist of a cylinder, a movable guide rod, and a pressing plate for pressing material during the slitting process. The blade structure 75 specifically includes a blade holder and blades. A slide rail structure can be installed on the slitting platform 72, mounting the blade holder on the slide rail structure and connecting it to the blade holder via a belt seat on the belt conveyor structure 74, allowing the blade holder to move and thus driving the blades mounted on the blade holder to move, achieving slitting.

[0058] This process involves slitting and forming medium-efficiency air filter bags. The pre-welded medium-efficiency air filter bags are pulled in by the material pulling structure, and then the material is fixed by the material pressing structure 73. The blade structure 75 moves on the slitting platform 72 under the action of the belt conveyor structure 74. At the same time, the slitting platform 72 moves back and forth on the frame 1 through the action of the screw structure 71 to control the length of the medium-efficiency air filter bags, so that the medium-efficiency air filter bags are slitting and forming.

[0059] More specifically, in this embodiment, a stacking machine can be fixedly installed on the right side of the slitting component 7 to stack the products.

[0060] It should be noted that in the above embodiments, the welding parts all use ultrasonic welding structures. In the processing unit, ultrasonic generators and welding heads are respectively set, and multiple ultrasonic electronic boxes are placed on the placement rack to correspond to multiple ultrasonic generators, so as to realize the ultrasonic welding function.

[0061] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
