Description

Technical Field

[0001] This utility model relates to the field of ultrasonic composite device technology, specifically to an ultrasonic composite device for air filter bags. Background Technology

[0002] Air filter bags are devices used to filter impurities in the air and are widely used in air conditioning, ventilation and dust removal systems. In the production of air filter bags, ultrasonic composite technology is a highly efficient and precise processing technology, especially suitable for the manufacture of filter bags with high requirements for sealing, temperature resistance or material compatibility. Ultrasonic composite machines are usually required. In existing technologies, ultrasonic laminating machines utilize the high-frequency mechanical energy generated by ultrasonic vibrations to rapidly generate heat through friction at the filter material contact surfaces, achieving fusion at the molecular level. This replaces traditional sewing or adhesive bonding, improving the sealing, durability, and filtration stability of air filter bags. However, for multi-layer composite filter materials, high-frequency vibrations may cause fiber breakage or excessive stretching in the filter material (especially fine, fluffy meltblown fabric and microfiber filter materials), damaging the original pore structure (such as increased pore size and uneven distribution), potentially leading to substandard filter bag production. Utility Model Content

[0003] To overcome the above-mentioned defects, embodiments of this utility model provide an ultrasonic composite device for air filter bags, which solves the technical problem in the prior art that high-frequency vibration may cause fiber breakage or excessive stretching of filter material, thereby damaging the original pore structure.

[0004] According to one aspect, at least one embodiment of the present invention provides an ultrasonic composite device for air filter bags, including a composite machine body. The composite machine body includes a frame, and further includes movable seats, support rollers, guide supports, and a drive mechanism. Two movable slots are symmetrically opened in the frame, and two movable seats are longitudinally movable in the movable slots. The support rollers are rotatably disposed in the two movable seats through rotating components for supporting and conveying filter media. Two guide supports are symmetrically arranged in the frame for elastically supporting the movable seats. The drive mechanism is disposed on the frame for driving the movable seats to move longitudinally and adjusting the tension on the filter media.

[0005] Preferably, the rotating component includes a mounting shaft and a limiting plate. The two ends of the mounting shaft are respectively embedded in the two movable seats and rotate with the movable seats. The two ends of the mounting shaft are coaxially fixedly connected to the limiting plate. The movable seat has a limiting groove that cooperates with the limiting plate. The limiting plate is rotatably disposed in the limiting groove.

[0006] Furthermore, the guide support includes a guide rod and a spring. One end of the guide rod is fixedly connected to the inner top wall of the moving groove. The guide rod passes through the moving seat and slides with the moving seat. The spring is sleeved on the outer wall of the guide rod, and one end of the spring is fixedly connected to the moving seat.

[0007] Furthermore, the drive mechanism includes a mounting plate, an electric cylinder, and an abutment plate. The mounting plate is fixedly connected to the outer side wall of the frame. The electric cylinder is mounted on the mounting plate, and its output end extends through the mounting plate. One end of the abutment plate is fixedly connected to one end of the movable seat.

[0008] As a further aspect of this application, in order to enable the mounting shaft to move longitudinally during rotation, two through slots that symmetrically cooperate with the mounting shaft are provided on the frame.

[0009] As a further aspect of this application, in order to enable the pressure sensor to detect the pressure on the support roller from the filter media and to drive the electric cylinder to move the moving seat longitudinally, thereby adjusting the contact tension between the support roller and the filter media, a pressure sensor is installed on the inner bottom wall of one of the moving grooves. One end of the pressure sensor is fixedly connected to the other end of a spring, and the pressure sensor is electrically coupled with the electric cylinder.

[0010] Based on the aforementioned solution, in order to avoid the guide rod from contacting the pressure sensor and to prevent the movable seat from detaching from the guide rod, the distance between the other end of the guide rod and the inner bottom wall of the movable groove is less than the width of the movable seat.

[0011] Furthermore, in order to connect the abutment plate to the movable seat and allow it to move longitudinally along the frame, and to prevent the movable seat from dislodging from the moving groove, a sliding groove is provided on the frame to cooperate with the abutment plate. The width of the sliding groove and the through groove are both smaller than the width of the moving groove.

[0012] The beneficial effects of this utility model are as follows: In this invention, through the cooperation of a movable seat, support roller, guide support, pressure sensor, and drive mechanism, the multi-layer filter media undergoes pressing and conveying. The rotation of the support roller provides support and assists in conveying the filter media, while also tensioning it. By starting an electric cylinder, the support roller moves longitudinally, adjusting the height of the filter media on it. This allows for adjustment of the compressive force exerted by the filter media on the support roller. A spring exerts pressure on the pressure sensor. When the pressure sensor receives a suitable value, the electric cylinder stops driving, and the support roller is at a suitable height. This adjusts the tension on the filter media, preventing excessive stretching and damage. Attached Figure Description

[0022] like Figures 1-5 As shown, it illustrates an ultrasonic composite device for air filter bags according to an embodiment of the present invention, including a composite machine body 1, the composite machine body 1 including a frame 2, a winding mechanism 17 is provided on one side of the frame 2 for winding multiple layers of filter material to be composited, and a winding mechanism 18 is provided on the other side of the frame 2 for winding the composited filter material. It also includes a movable seat 3, a support roller 5, a guide support and a drive mechanism. Two movable slots 4 are symmetrically opened inside the frame 2. Two movable seats 3 are longitudinally movable inside the movable slots 4. The outer side wall of the movable seat 3 abuts against and slides with the inner wall of the movable slot 4. like Figure 4 As shown, the support roller 5 is rotatably mounted in two movable seats 3 via a rotating component, used to support and convey filter media. The rotating component includes a mounting shaft 6 and a limiting plate 7. The two ends of the mounting shaft 6 are respectively embedded in the two movable seats 3 and rotate with the movable seats 3. In order to allow the mounting shaft 6 to move longitudinally during rotation, two through slots 14 that cooperate with the mounting shaft 6 are symmetrically opened on the frame 2. The two ends of the mounting shaft 6 are coaxially fixedly connected to the limiting plate 7. The limiting plate 7 has a circular cross-section and its cross-sectional area is larger than that of the mounting shaft 6. A limiting groove 8 that cooperates with the limiting plate 7 is opened in the movable seat 3. The limiting plate 7 is rotatably mounted in the limiting groove 8, so that the support roller 5 can be rotatably mounted between the two movable seats 3. It should be added that the support roller 5 is located between the unwinding mechanism 17 and the winding mechanism 18, which can tension the filter material and also support and transport the filter material. like Figure 3 As shown, two guide supports are symmetrically arranged inside the frame 2 for elastically supporting the movable seat 3. The guide supports include a guide rod 9 and a spring 10. One end of the guide rod 9 is fixedly connected to the inner top wall of the movable groove 4. The guide rod 9 passes through the movable seat 3 and slides with the movable seat 3. The outer wall of the guide rod 9 is fitted with a spring 10. One end of the spring 10 is fixedly connected to the movable seat 3. It should be added that the damping coefficient of spring 10 is relatively high, which can "support" the moving seat 3 and the support roller 5. With the cooperation of the two guide rods 9, the frame 2 and the moving seat 3, the support roller 5 can be kept in a horizontal state and can move longitudinally. like Figure 3 As shown, in order for the pressure sensor 15 to detect the pressure from the filter media on the support roller 5 and to drive the electric cylinder 12 to move the moving seat 3 longitudinally, thereby adjusting the contact tension between the support roller 5 and the filter media, a pressure sensor 15 is installed on the inner bottom wall of a moving groove 4. One end of the pressure sensor 15 is fixedly connected to the other end of a spring 10. The pressure sensor 15 is electrically engaged with the electric cylinder 12. It should be added that the other end of another spring 10 (the spring 10 in the moving groove 4 where the pressure sensor 15 is not installed) is fixedly connected to the inner bottom wall of the moving groove 4. In order to prevent the guide rod 9 from abutting against the pressure sensor 15 and to prevent the moving seat 3 from detaching from the guide rod 9, the distance between the other end of the guide rod 9 and the inner bottom wall of the moving groove 4 is less than the width of the moving seat 3. When the bottom end of the moving seat 3 abuts against the inner bottom wall of the moving groove 4, the moving seat 3 is still "connected" to the guide rod 9 in the moving groove 4. It should be added that the maximum displacement of the movable seat 3 makes it difficult for the bottom end of the movable seat 3 to abut against the inner bottom wall of the movable groove 4, because at this time the spring 10 is almost compressed to the "limit" state, and the spring 10 will generate directional elastic force after being compressed, which can be used to support the support roller 5. The drive mechanism is mounted on the frame 2 and is used to drive the movable seat 3 to move longitudinally, adjusting the tension of the filter media. The drive mechanism includes a mounting plate 11, an electric cylinder 12, and an abutment plate 13. The mounting plate 11 is fixedly connected to the outer wall of the frame 2. The electric cylinder 12 is mounted on the mounting plate 11, and its output end extends through the mounting plate 11. One end of the abutment plate 13 is fixedly connected to one end of a movable seat 3. By activating the electric cylinder 12, its output end drives the abutment plate 13 to move longitudinally, which in turn drives the movable seat 3 to move longitudinally. The mounting shaft 6 moves longitudinally, driving another moving seat 3 to move longitudinally, which in turn drives the support roller 5 to move longitudinally. The height of the filter media on the support roller 5 can be adjusted, thus adjusting the squeezing force exerted by the filter media on the support roller 5. The moving seat 3 squeezes the spring 10, causing the spring 10 to contract and one of the springs 10 to exert pressure on the pressure sensor 15. When the pressure value received by the pressure sensor 15 is appropriate, the drive of the electric cylinder 12 is stopped. At this time, the support roller 5 is at a suitable height, and the tension force on the filter media is adjusted, preventing the filter media from being overstretched and damaged. It should be added that the electric cylinder 12 is equipped with a controller that matches the pressure sensor 15. The pressure sensor 15 is adjusted to the corresponding value before use. This value can keep the filter material under the support of the support roller 5 with appropriate tension. In order to connect the abutment plate 13 with the movable seat 3 and move longitudinally along the frame 2, and to prevent the movable seat 3 from dislodging from the moving groove 4, the frame 2 is provided with a sliding groove 16 that cooperates with the abutment plate 13. The width of the sliding groove 16 and the through groove 14 is smaller than the width of the moving groove 4. Working Principle: During the ultrasonic composite device for air filter bags, the filter material is placed on the unwinding mechanism 17 and the winding mechanism 18 for ultrasonic composite bonding of multiple layers of filter media. The composite machine body 1 operates, using ultrasonic technology to achieve the composite welding of the multiple layers of filter media. The winding mechanism 18 drives the composited filter material to be conveyed. During this process, the support roller 5 rotates, providing support and assisting in the conveying of the filter material. The support roller 5 also provides tension to the filter material. By activating the electric cylinder 12, the output end of the electric cylinder 12 drives the abutment plate 13 to move longitudinally. The abutment plate 13 then drives a moving seat 3 to move longitudinally. The movable seat 3 drives the mounting shaft 6 to move longitudinally, and the mounting shaft 6 drives another movable seat 3 to move longitudinally. This drives the support roller 5 to move longitudinally, and the height of the filter media on the support roller 5 can be adjusted. This adjusts the squeezing force of the filter media on the support roller 5. The movable seat 3 squeezes the spring 10, the spring 10 contracts, and one of the springs 10 exerts pressure on the pressure sensor 15. When the pressure value received by the pressure sensor 15 is appropriate, the drive of the electric cylinder 12 stops. At this time, the support roller 5 is at a suitable height, and the tension of the filter media is adjusted to avoid the filter media being overstretched and damaged.
