Description

Technical Field

[0001] This utility model belongs to the field of filter bag production technology, and specifically relates to a quick-access guide bracket for welding the bag opening of a filter bag. Background Technology

[0002] Filter bags possess excellent chemical stability and heat resistance, representing the highest performance in the filter media industry and the most advanced type of commonly used filter materials, achieving high levels in filtration efficiency and precision.

[0003] In the filter bag production process, the welding of the filter bag opening to the plastic ring is crucial. Filter bags are generally made of polyester, polypropylene, nylon, or similar materials. These materials are soft and easily deformed. During the ultrasonic welding process, workers need to place the plastic ring on the mounting plate of the ultrasonic welding equipment, then place the filter bag opening to be welded onto the plastic ring for fixation, and then start the ultrasonic welding device. In this process, workers need to use both hands to hold the filter bag opening and the plastic ring to ensure a tight fit, which carries the risk of being crushed or burned by the welding head. At the same time, the labor intensity and production efficiency are low because both hands are needed to fix the soft filter bag opening to the plastic ring. To address this problem, designing a quick-access guide bracket for filter bag opening welding has become a problem that we need to solve. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-access filter bag opening welding support.

[0005] To achieve the above objectives, this utility model provides a quick-access filter bag inlet welding bracket, comprising a bracket, a plastic ring fitted onto the outer wall of the bracket, a filter bag fitted onto the outer wall of the bracket and the plastic ring, a rotating rod rotatably connected inside the bracket, and a threaded end of the rotating rod near the plastic ring on its outer wall; and a pressing assembly, which assists the operator in pressing the filter bag tightly against the outer wall of the plastic ring, and is connected to the bracket and the rotating rod.

[0006] In the above technical solution, the clamping assembly further includes a sliding sleeve fixedly connected to the outer wall of the rotating rod, and two push plates are slidably connected inside the sliding sleeve.

[0007] In the above technical solution, furthermore, each of the two push plates is fixedly connected to an elastic plate at the end away from the sliding sleeve, and the elastic plate is provided with a weakening groove.

[0008] In the above technical solution, a connecting plate is sleeved on the outer wall of the rotating rod, and a sliding groove is opened inside the connecting plate.

[0009] In the above technical solution, further, the outer walls of the two push plates are fixedly connected with sliders, the sliders are inserted into the inside of the slide groove, and the inside of the slide groove is provided with multiple positioning slots in a sequentially equidistant manner.

[0010] In the above technical solution, a sleeve rod is further fixedly connected to the side of the connecting plate away from the opening of the sliding groove and the positioning slot. The sleeve rod is fixedly connected to the inner wall of the bracket and rotatably connected to the outer wall of the rotating rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects: By setting up a clamping component, the filter bag can be automatically opened when the operator rotates the plastic ring and filter bag using the bracket. This allows the filter bag opening to fit tightly against the plastic ring at the bottom of the ultrasonic welding head, eliminating the need for the operator to use their hands to fix the filter bag opening to the plastic ring. This avoids the risk of the operator's hands being crushed or burned by the ultrasonic welding head. Furthermore, the operator does not need to manually fix the plastic ring and filter bag together, which improves the welding efficiency of the plastic ring and filter bag, thereby increasing production efficiency. By using a bracket, a rotating rod, and threads, the filter bag can be quickly fitted onto the plastic ring. The bracket also supports the filter bag, preventing it from sagging and detaching from the plastic ring. This design also reduces the need for modifications to the ultrasonic welding equipment. Only a threaded hole corresponding to the thread needs to be drilled on the mounting plate of the ultrasonic welding equipment for quick installation, making actual modifications convenient.

[0014] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1 to 3 The illustrated quick-access filter bag opening welding bracket includes a bracket 1, a plastic ring 2 fitted onto the outer wall of the bracket 1, and a filter bag 3 fitted onto the outer walls of the bracket 1 and the plastic ring 2. A rotating rod 4 is rotatably connected inside the bracket 1. A thread 5 is formed on the outer wall of the rotating rod 4 near the plastic ring 2. The bracket 1 is threadedly connected to the mounting plate of an ultrasonic welding equipment via the thread 5 on the rotating rod 4. This design reduces modifications to the ultrasonic welding equipment; only a threaded hole corresponding to the thread 5 needs to be made on the mounting plate of the ultrasonic welding equipment for quick installation and convenient modification. A clamping component assists the operator in pressing the filter bag 3 tightly against the outer wall of the plastic ring 2. The clamping component is connected to the bracket 1 and the rotating rod 4.

[0016] like Figures 2 to 4 As shown, the clamping assembly includes a sliding sleeve 6 fixedly connected to the outer wall of the rotating rod 4. Two push plates 7 are slidably connected inside the sliding sleeve 6. Due to the weakening grooves on the push plates 7, when the push plates 7 drive the elastic plates 8 to rotate relative to the bracket 1, if the bracket 1 encounters either the push plate 7 or the elastic plate 8, the push plate 7 will bend from the position of the weakening groove to avoid jamming the bracket 1. This continues until the push plates 7 and elastic plates 8 return to their original position through their own elasticity after passing the bracket 1. The ends of the two push plates 7 furthest from the sliding sleeve 6 are each fixedly connected to an elastic plate 8, which has a weakening groove 9. The weakening groove 9 is designed to prevent the elastic sheet 8 from exerting too much force on the filter bag 3. The outer wall of the rotating rod 4 is fitted with a connecting plate 11. The connecting plate 11 has a sliding groove 12 inside. The outer walls of the two push plates 7 are fixedly connected with sliders 10. The sliders 10 are inserted into the sliding groove 12. The sliding groove 12 has multiple positioning slots 13 arranged in a sequential and equidistant manner inside. The side of the connecting plate 11 away from the sliding groove 12 and the positioning slots 13 is fixedly connected with a sleeve rod 14. The sleeve rod 14 is fixedly connected to the inner wall of the bracket 1 and rotatably connected to the outer wall of the rotating rod 4.

[0017] Working principle: When the operator needs to weld the plastic ring 2 to the filter bag 3, first, the plastic ring 2 is placed on the bracket 1 and pushed to slide along the outer wall of the bracket 1 until it is on the outer wall of the mounting plate of the ultrasonic welding equipment. Then, the filter bag 3 is fitted onto the bracket 1 and the outer wall of the plastic ring 2 until the opening of the filter bag 3 is fitted onto the outer wall of the plastic ring 2. This achieves the effect of quickly fitting the filter bag 3 onto the plastic ring 2. At this time, the bracket 1 can support the filter bag 3 and prevent it from falling off the plastic ring. After the filter bag 3 is disengaged, the operator can rotate the support 1 through the filter bag 3 (note that the support 1 can only rotate in one direction). This causes the support 1 to rotate synchronously with the plastic ring 2, the filter bag 3, and the sleeve rod 14. The sleeve rod 14 then rotates the connecting plate 11, causing the connecting plate 11 to rotate relative to the slider 10 via the sliding groove 12 and the positioning slot 13. The slider 10 continues to rotate until it slides into one of the positioning slots 13. During this process, the slider 10 slides along the inside of the sliding groove 12, pushing the pusher 7 to gradually disengage from the inside of the sliding sleeve 6. The pusher 7 then causes the elastic plate 8 to press against and open the filter bag 3 from the inside, allowing the portion of the filter bag 3 pressed against by the elastic plate 8 to be opened to both sides. This ensures that the opening of the filter bag 3 is tightly fitted to the plastic ring 2 at the bottom of the ultrasonic welding head, eliminating the need for the operator to use their hands to fix the opening of the filter bag 3 to the plastic ring 2, thus preventing the operator's hands from being crushed or burned by the ultrasonic welding head. The operator only needs to rotate the support 1 and control the ultrasonic welding equipment to achieve the desired result. Once welding of 102 and 103 is completed, there is no need to manually fix the plastic ring 2 and filter bag 3 together, which can improve the welding efficiency of the workers and thus improve production efficiency. It should be noted that by setting the positions of the sliding groove 12 and positioning slot 13 on the connecting plate 11, when the slider 10 on the push plate 7 slides to the position of any one of the positioning slots 13 on the sliding groove 12, the elastic piece 8 on the push plate 7 will be offset from the position of the bracket 1, so as to avoid the elastic piece 8 being blocked and jammed by the bracket 1.
